NKS-3 Heating and Smoke Tester (Catalog), [0nline], September 27, 2013, NITTAN Corporation, [Search on March 25, 2016], Internet <URL: http: // www. nittan.com/download/pdf/k1105.pdf>

  Although the heating tester of the above-mentioned patent document 1 and patent document 2 can be used in a limited time, it can replace the heating tester using catalytic reaction, and the whole building which is a fire prevention object It was not intended to allow continuous testing. Furthermore, it did not generate as much heat as necessary when needed.

  The heating tester disclosed in Patent Document 3 uses a heater, but an electric wire for supplying power to the heater is exposed between the heating tester main body and its support bar. Therefore, when there is an obstacle around the fire detector to be tested or when the surrounding space is narrow, there is a possibility that the electric wire may be caught on the obstacle.

  In the heating tester of Non-Patent Document 1, the angle between the main body provided with the heating means and the support rod is connected by a hinge portion that can be fixed in six stages, and is not exposed through a power supply wire. However, if the angle between the main unit and the support bar does not match due to the surroundings of the fire detector being tested, it is necessary to lower the tester and reset the hinge angle once, and repeat trial and error several times. There is a risk that.

  In view of the above circumstances, the present invention can repeatedly perform an operation test of a fire detector at any timing without using a combustible material, and can fix the angle between the main body and the support bar. The purpose is to obtain a heating tester that can prevent an electric wire from being caught by an obstacle around a fire detector.

  The present invention includes a main body having a heating means for heating and operating a heat-sensitive fire detector, and a tester attaches the main body to a tip of a support rod that supports the fire detector toward the fire detector to perform an operation test. A heating tester, wherein the heating means includes a heating element composed of a heating wire, and a cylindrical body that houses the heating element and is open at both ends, and the main body is one end of the cylindrical body. A blower that blows air to the other end in order to blow out hot air from the battery, and a battery power supply that supplies electric power for driving the heating means and the blower. The battery power supply includes the heating means and the blower. It is a heating tester characterized by being connected to the means and the inside of the main body.

  Further, according to the present invention, the heating unit includes a thermal radiation suppressing unit, and the battery power source is provided below the main body by providing the air blowing unit near the side of the heating unit and above the main body. It is a heating tester characterized in that a storage space is formed.

  Further, according to the present invention, the main body is provided with an opening for attaching and detaching the battery power source, a cover for closing the opening, and a lock member for preventing the battery power source from falling off. It is a heating tester characterized in that a mechanism that does not close the cover unless it is in a locked state to prevent dropping is configured.

  The cylindrical body may be a cylindrical outer cylinder having both ends opened, and an inner cylinder made of a heat-resistant material having both ends opened apart from the outer cylinder. The heating element is housed in the inner cylinder, and one opening of each of the inner cylinder and the outer cylinder can be used as an air inlet and the other opening can be used as an outlet.

  According to the present invention, since the fire detector is heated by the high-temperature wind using the heating wire as a heat source, the fire detector can be repeatedly tested at an arbitrary timing without using a combustible material. Moreover, since the electric wire which supplies electric power to the heating tester main body from the outside becomes unnecessary, the angle between the main body and the support rod is not fixed, and the electric wire is not caught by an obstacle around the fire detector.

  Therefore, according to this invention, without using a combustible material, it is possible to repeatedly perform an operation test of the fire detector at an arbitrary timing, and without fixing the angle between the main body and the support bar, It is possible to obtain a heating tester that can prevent an electric wire from being caught by an obstacle around the fire detector.

  Further, according to the present invention, since the heating means includes the thermal radiation suppressing means, the blower means can be provided close to the side of the heating means. And since a ventilation means can be arranged side by side with a heating means above a main body, the space which accommodates a battery power supply can be formed under a heating means and a ventilation means, ie, the downward direction of a main body. Since a large space for storing the battery power supply in the main body can be secured, the capacity of the battery power supply can be increased.

  Further, according to the present invention, the battery power source can be attached and detached from the opening of the main body, and the cover cannot be closed unless the lock member is in a locked state that prevents the battery power source from dropping off. Since the cover cannot be closed unless the power supply is securely stored and fixed in the main body, it is possible to prevent the battery power supply from being accidentally dropped.

It is. FIG. 5 is a side view showing an example of an embodiment of the present invention, showing a side surface of a hood and a side wall of the main body long side of the main body, and (a) shows a side where an outside air inlet is provided on the side wall. (B) shows the side where the indicator lamp etc. which show an operation state are provided in the side wall. An example of embodiment of this invention is shown, (a) in a hood and a main-body part is a top view, (b) is a bottom view. It is an enlarged view of Fig.4 (a). (A) is an AA arrow directional cross-sectional view of Fig.4 (a), (b) is the principal part enlarged view of the cross-sectional view. FIG. 5 is a cross-sectional view taken along line B-B in FIG.

  First, referring to FIG. 1, the outline of the configuration of the heating tester 1 according to the present invention and the manner in which the operation test of the fire detector D is performed by the heating tester 1 attached to the tip of the support bar 5 will be briefly described. explain. Note that the fire detector D to be tested by the heating tester 1 is a thermal spot type fire detector, for example, a constant temperature spot type detector, a differential type spot type sensor, a compensation type spot type sensor. Etc.

  The heating tester 1 includes a main body 2, a hood 3 provided on the top thereof, and a bracket 4 that pivotally supports the main body 2 so as to support the main body 2 toward the fire detector D. Attached to the tip of the support bar 5 is used. For example, when performing an operation test of the fire detector D installed on the ceiling surface C, the tester H supports the main body 2 toward the fire detector D with the support bar 5, and the fire detector with the hood 3. While covering D, the upper end is brought into contact with the ceiling surface C, and the operation test is performed in this state (see FIG. 1). The hood 3 may cover the periphery of the detection unit of the fire detector D instead of covering the entire fire detector D. According to the heating tester 1, details will be described later. However, even when the operation test is performed immediately below the fire detector D as shown in FIG. It is possible to visually recognize L directly.

  Next, the configuration of the main body 2 and the hood 3 in the configuration of the heating tester 1 will be described in detail.

  The main body 2 has a substantially rectangular parallelepiped shape, and an operating means for operating the fire detector D is accommodated therein. Both side walls 2a and 2b on the long side are provided with shaft mounting portions 4c and 4d above the center of gravity of the heating tester 1, and both arm portions 4a and 4b of the substantially U-shaped bracket 4 are shaft mounting portions 4c. , 4d. The main body 2 is pivotally supported by the bracket 4 so as to be rotatable around an axis along the short side direction. In addition, in bracket 4, 4e is a connection part with support bar 5, The front-end | tip of support bar 5 is connected to the connection part 4e so that attachment or detachment is possible (refer FIG.1 and FIG.2).

  The hood 3 has a bottomed, generally cylindrical shape with an open upper end, and is provided on the top of the main body 2 as described above. The fire detector D is positioned inside the substantially cylindrical tubular portion 3a having the bottom portion 3b so as to cover the periphery thereof (see FIGS. 1 and 2). Here, in the case of this embodiment, the cylindrical part 3a and the bottom part 3b are separately formed, and both are joined. Specifically, the lower opening edge of the cylindrical portion 3a is inserted into a groove provided on the outer peripheral edge of the bottom portion 3b, thereby joining the two (see FIGS. 6 and 7). In addition, formation of the food | hood 3 is not restricted to this, For example, it is good also as what formed both by integral molding. 3c is a hood cover covering the entire circumference of the upper opening edge of the cylindrical portion 3a. Specifically, like the bottom part 3b, it is molded separately from the cylindrical part 3a, and the upper opening edge of the cylindrical part 3a is inserted into a recessed groove provided on the outer peripheral edge, thereby being joined to the cylindrical part 3a. (See FIG. 6 and FIG. 7). The formation of the hood cover 3c is not limited to this, and the hood cover 3c may be formed by integral molding with the cylindrical portion 3a, similarly to the bottom portion 3b.

  In the present embodiment, the heating tester 1 is such that the bottom 3b of the hood 3 is formed of a translucent member (transparent or translucent member). Specifically, all of the bottom 3b is formed as a translucent member. Further, a non-projecting portion that does not project directly below the bottom 3b of the hood 3 is provided on the side of the main body 2, and the side of the non-projecting portion is positioned directly below the translucent member 3b. It is assumed that a space S that does not block the line of sight to the operation confirmation lamp L provided with the light emitting region at the peripheral portion of the fire detector D to be tested is formed through the translucent member 3b. Specifically, the main body 2 has a substantially rectangular parallelepiped shape as described above, and flat side portions parallel to the direction immediately below the side walls 2a and 2b on the long side are the non-projecting portions, A space S that is located immediately below the translucent member 3b and that does not block the line of sight from the tester H directly below to the operation confirmation lamp L through the translucent member 3b is formed (FIGS. 1 and 2). reference).

  Therefore, according to the heating tester 1, the tester H himself / herself performs the test through the space S on the side of the non-projecting portion of the main body 2 and the translucent member 3b even from just below the fire detector D. The operation confirmation lamp L of the fire detector D is visible. That is, the tester H himself / herself can recognize the operation of the fire detector D being tested, and one person can perform the operation test of the fire detector D (see FIGS. 1 and 2). Even if the operation confirmation lamp L is not located at the peripheral edge of the fire detector D, the light emission area of the operation confirmation lamp L is the peripheral edge of the fire detector D and the position corresponding to the translucent member 3b. If the tester H is directly under the fire detector, the light emitted from the operation confirmation lamp L can be visually recognized.

  In addition, the heating tester 1 has a shape in which the main body 2 is projected directly below, and has a substantially rectangular shape, and its short side is located inside the periphery of the bottom 3 b of the hood 3. Specifically, the main body 2 has a substantially rectangular parallelepiped shape, and all of the top four sides are located inside the periphery of the bottom 3b of the hood 3 (see FIG. 4b). According to this heating tester 1, the line of sight from the examiner H directly below the translucent member is not obstructed in the space S formed on the side of the side walls 2a and 2b, which are the non-projecting portions of the main body 2. The volume of the main body 2 can be secured with a sufficient size while securing a sufficient size.

  Furthermore, in the case of the present embodiment, a plurality of protrusions 3d made of an elastic body (for example, an elastomer) are provided on the outer periphery of the bottom 3b of the hood 3 and project outward (see FIGS. 4 and 5). These protrusions 3d can prevent the heating tester 1 from rolling. Further, these protrusions 3d can absorb the impact and prevent the impact from being applied to the inside of the heating tester 1.

  Specifically, the plurality of protrusions 3d protrude outwardly in a shape that forms a corner at the tip, but the tip of the protrusion 3d may be rounded. Further, it is assumed to be continuous in the circumferential direction so as to form a polygonal shape in plan view, and to have a shape in which the corners of the four corners of the quadrangle are cut out in a substantially V shape in plan view (see FIG. 4 and FIG. 4). (See FIG. 5). In the present embodiment, the plurality of protrusions 3d have a thinned portion, and have a shape that is easily crushed against external force and easily absorbs an impact.

  Further, in the heating tester 1, the main body 2 is also provided with an impact absorbing member 2c made of an elastic body. The shock absorbing member 2c has a frame shape along the outer shape of the main body 2, and is provided at the bottom of the main body 2 (see FIG. 4b). The impact absorbing member 2c can also prevent an impact from being applied to the inside of the heating tester 1, and in particular, can prevent an impact from being applied to the inside of the main body 2.

  In addition, although the hood cover 3c is provided in the upper opening edge of the hood 3, the hood cover 3c can also be made of an elastic body, and the hood cover 3c may absorb the impact.

  Here, as for the material of the hood 3, at least a part of the bottom 3b forming the space S immediately below may be made of a translucent member, but the entire bottom 3b is made of a translucent member. It is good. Further, the entire hood 3 including the cylindrical portion 3a, the hood cover 3c, and the protruding portion 3d may be made of a translucent member, and this makes it possible to visually recognize the operation confirmation lamp from a wide direction. It is preferable in that it can be done. Moreover, you may form the bottom part 3b as a translucent member and an elastic body with the projection part 3d. In that case, for example, it can be made of transparent or translucent silicone rubber. Similarly, the hood cover 3c can be made of, for example, transparent or translucent silicone rubber. The cylindrical portion 3a can be made of, for example, a transparent or translucent plastic without being an elastic member.

  Next, in the configuration of the heating tester 1, the configuration of the heating means 6 and the blowing means 7 will be described in detail.

  The heating tester 1 includes a heating unit 6 and an air blowing unit 7 inside the main body 2 as an operation unit of the heat detector type fire detector D.

  The heating means 6 includes a cylindrical outer cylinder 6a having both ends opened, an inner cylinder 6b made of a cylindrical heat-resistant material that is separated from the outer cylinder 6a and housed inside and opened at both ends, and an inner cylinder. And a heating element 6c made of a heating wire housed in 6b. In this heating means 6, the opening toward the lower side of the outer cylinder 6a is used as the inlet 6d (between the outer cylinder 6a and the inner cylinder 6b), and the opening toward the upper side is the outlet 6f (outer cylinder 6a and inner cylinder 6b). Between). In addition, an opening toward the lower side of the inner cylinder 6b is used as an inlet 6e, and an opening toward the upper side is used as an outlet 6g (see FIG. 6b). The heating means 6 is provided in the upper center part of the main body 2. Further, there is provided a top opening 2d communicating with the bottom opening 3f provided in the bottom 3b of the hood 3 attached to the top of the main body 2 and communicating with the outlets 6f and 6g of the inner cylinder and the outer cylinder of the heating means 6. It has been. As a result, the high temperature air blown from the outlets 6f and 6g of the heating means 6 (particularly the outlet 6g of the inner cylinder 6b) blows into the hood 3 through the top opening 2d of the main body 2 and the bottom opening 3f of the hood 3. It has come to be.

  The air blowing means 7 blows the air sucked from the outside air inlet 2e to the inlets 6d and 6e of the heating means 6 (see arrow A1 in FIG. 6b), and the air from the inlet 6e of the inner cylinder 6b toward the outlet 6g. The air is blown so as to pass through the inner cylinder 6 (see the arrow A2), and the air is blown so as to pass between the outer cylinder 6a and the inner cylinder 6b from the inlet 6d of the outer cylinder 6a toward the outlet 6f. (Refer to the arrow A3).

  The heating means 6 and the air blowing means 7 are provided as described above, and heat the fire detector D by applying hot air that is heated by the heating element 6c and blown out from the inner cylinder 6b into the hood 3. On the other hand, when the air blowing means 7 flows air between the inner cylinder 6b and the outer cylinder 6a, the heat of the inner cylinder 6b is prevented from being transmitted to the outer cylinder 6a, and heat radiation from the outer cylinder 6a to the inside of the main body 2 is suppressed. It comes to suppress.

  Therefore, according to this heating tester 1, since the fire detector D is heated by the high-temperature wind using a heating wire as a heat source, the operation test of the fire detector D is repeatedly performed at any timing without using combustible materials. It can be carried out. Moreover, since the heat radiation to the inside of the heating tester 1 is suppressed, the mounting density in the main body 2 can be increased, and the heating tester 1 can be miniaturized. Furthermore, even if the heating output is increased, for example, even if the heating output is increased to such an extent that the fire rate detector with an operating temperature of 150 ° C. can be operated, the heat damage in the main body 2 can be prevented, It is possible to prevent the heat tester 1 from being damaged by heat.

  In the present embodiment, the heating element 6c is wound while being separated in the blowing direction by the blowing means 7, and has a winding portion of the heating element 6c that generates a substantially annular heating region R (see FIG. 5). ing.

  Thus, the air blown from the blowing means 7 to the inlet 6e of the inner cylinder 6b passes through the inner peripheral side R ′ and the outer peripheral side R ″ of the substantially annular heating region R, and the outlet of the inner cylinder 6b. Since the fire detector D is heated by being blown into the hood 3 as a high-temperature air having an annular high-temperature distribution region from 6 g, it is possible to prevent the heating from concentrating on one point and to burn the fire detector D. Can be prevented.

  Further, in the case of the present embodiment, the air blowing means 7 is located on the side of the heating means 6 and is provided inside the main body 2 in a direction along the side wall 2a of the main body 2, and is an example of a centrifugal fan that can be formed thin. It is a turbo fan. Further, the air blowing means 7 serving as the centrifugal fan has an air outlet 7c that blows out air sucked from the air inlet 7a downward, and an air passage 8 provided below the air blown from the air outlet 7c. The air is sent to the inlets 6d and 6e of the heating means 6 (see arrow A1 in FIG. 6b).

  Thereby, the thickness of the main body 2 can be made thin by forming the thickness thin while the air blowing means 7 is positioned on the side of the heating means 6. Moreover, since the heating means 6, the air blowing means 7, etc. are concentrated on the upper part of the main body 2, a space can be secured below them, and the space can be used as a mounting space for other components and members. . For example, as will be described in detail later, it can be used as a storage space for the battery power source 12 that drives the heating means 6, the blowing means 7, and the like.

  The air blowing means 7 sucks the air inside the main body 2 in addition to the first air inlet 7a that sucks outside air through the outside air inlet 2e provided on the side wall 2a of the main body 2 as an air inlet. The second air inlet 7b may be provided.

  Thereby, the air inside the main body 2 can be discharged to the outside through the heating means 6, preventing heat from accumulating inside the main body 2, and thereby preventing heat damage inside the main body 2. it can. As a result, the air blowing means 7 attached to the side wall 2a of the main body 2 can be provided close to the case where the air blowing means 7 is positioned on the side of the heating means 6, and the thickness of the main body 2 can be reduced.

  Here, in this embodiment, specifically, the air blowing means 7 is configured by housing a fin for blowing air in a centrifugal direction in a box-shaped fan case 7d having a small thickness, and one side surface of the main body 2 is It is provided in an arrangement close to or in contact with the side wall 2a. Furthermore, when the first intake port 7a is provided on one side surface of the fan case 7d so as to open toward the outside air introduction port 2e, and the second intake port 7b is provided, The other side surface is provided open toward the heating means 6 side, and the exhaust port 7c is provided on the bottom surface toward the inlet 8a side which is one end opening of the ventilation path 8. It has been. As described above, in this embodiment, a turbo fan is used as a centrifugal fan that can be formed thin. However, the present invention is not limited to this, and other centrifugal fans such as a sirocco fan blow air in various centrifugal directions. A blower can be used.

  Further, the air passage 8 is specifically provided such that the inlet 8a which is one end opening thereof opens toward the exhaust port 7c side of the air blowing means 7. In addition, the inlet 8a of the ventilation path 8 may be provided so as to contact and communicate with the exhaust port 7c of the blowing means 7. In addition, an outlet 8 b that is the other end opening of the ventilation path 8 is provided so as to open toward both the inlets 6 d and 6 e of the heating means 6. Further, the ventilation path 8 is provided so as to form a substantially U-shaped flow path as a whole, and a first deflection section that changes the air direction from the lower side to the side in the flow path. 8c and a second deflecting portion 8d that changes from the side toward the upper side. The deflection portions 8c and 8d are both formed as curved surfaces so as to reduce air resistance. The outlet 8b may be provided with a rectifying means such as a net so that the air sent to the heating means 6 is equalized.

  As described above, the heating means 6 includes the inner cylinder 6b made of a heat-resistant material. Specifically, the inner cylinder 6b can be made of, for example, ceramics or ceramics. Further, as described above, it has an outer cylinder 6a in which the inner cylinder 6b is accommodated, and by flowing air between the outer cylinder 6a and the inner cylinder 6b, the inner cylinder 6b and the outer cylinder 6a are interposed. An air flow for heat insulation is generated, and heat radiation from the outer cylinder 6a to the inside of the main body 2 is suppressed. The outer cylinder 6a can be made of a metal material such as stainless steel, but can be made of a resin material having high heat resistance or a heat insulating material. By forming the outer cylinder 6a from a heat insulating material, heat radiation from the inner cylinder 6b can be further blocked by the outer cylinder 6a, and heat radiation from the outer cylinder 6a to the inside of the main body 2 can be further suppressed.

  In the heating means 6, the heating element 6c has a winding portion that generates a substantially annular heating region R as described above. In the case of the present embodiment, the winding portion is disposed away from the inner wall of the inner cylinder 6b and wound in a coil shape. Although it is good also as what was wound in other modes, it is easy to process by having been wound in the shape of a coil, and the winding part which generates the above-mentioned approximately annular heating zone R is provided. Can be easily obtained.

  Further, the heating tester 1 includes a printed circuit board 9 for controlling the heating means 6 and the air blowing means 7 in the main body 2. As described above, by blowing air between the outer cylinder 6a and the inner cylinder 6b, heat radiation from the outer cylinder 6a can be suppressed, and furthermore, air inside the main body 2 is sucked by the blowing means 7. Therefore, heat can be prevented from accumulating inside the main body 2. Therefore, even if the heating means 6 is provided inside the main body 2 as in the heating tester 1, heat damage to the printed circuit board 9 provided inside the main body 2 can be prevented.

  For this reason, the printed circuit board 9 can be provided on the side opposite to the air blowing means 7 with the heating means 6 interposed therebetween. That is, since the air blowing means 7, the heating means 6 and the printed circuit board 9 are arranged side by side in the short side direction of the main body 2 in a concentrated manner in the space on the top side, a large space is formed below the inside of the main body 2. Can be secured. The lower space can be used as a storage space for various components such as the battery power source 12.

  Further, as described above, the heating tester 1 can prevent heat damage to the components inside the main body 2, so that even if the battery power source 12 or the like is stored inside the main body 2, Can prevent harm. The printed circuit board 9 is provided on the side wall 2b opposite to the side where the air blowing means 7 is provided, with the heating means 6 preferably disposed in the center for heating the fire detector D. Alternatively, they are provided close to each other along the side wall 2b. Also by this, the thickness of the main body 2 can be reduced.

  Furthermore, the heating tester 1 includes a proximity sensor 10 at the top of the main body 2, and starts the test by energizing the heating element 6c of the heating means 6 when the distance from the fire detector D becomes a predetermined value or less. In other cases, it is also possible not to energize and not start the test.

  As a result, before the heating tester 1 approaches the fire detector D to be tested, it is possible to prevent energization more than necessary, and as a result, the battery power source can be maintained for a long time and repeatedly tested. The proximity sensor 10 is provided because, as described above, it is possible to prevent thermal damage to the components inside the main body 2. In the present embodiment, the proximity sensor 10 is provided on the side of the heating means 6 (the side on the long side of the main body 2), and the sensor opening formed at the top of the main body 2. The sensor part is exposed from the window 2j toward the center of the top of the hood 3.

  Moreover, the heating tester 1 is provided with an indicator lamp 11 that displays its operating status. The indicator lamp 11 is provided together with the main power switch 13 and the operation switch 14 on the side surface of the side wall 2b on the side where the printed circuit board 9 is provided. As a result, the printed circuit board 9 requiring connection or the like, the indicator lamp 11, the main power switch 13, the operation switch 14 and the like can be provided close to each other, and can be integrated with the printed circuit board 9.

  Further, although not shown in the figure, it may further include output variable means for making variable the output of power from the battery power source 12 that drives the heating element 6c of the heating means 6. By providing such output variable means and changing the magnitude of the output or the rate of increase in the output according to the operating temperature of the fire detector D to be tested, the fire detector D is for high temperature operation, for example, the operating temperature is 150 ° C. Even with the compensation rate type constant temperature sensor, it is possible to obtain an operable output.

  In addition, the said indicator lamp 11 is the aspect which the tester H can grasp | ascertain these according to each operation condition of the heating test device 1, including the operation condition of the proximity sensor 10, the output condition of the said output variable means, etc. It can be displayed. This makes it possible for the tester H to appropriately grasp whether or not the test is being executed, the output setting status, and the like, thereby preventing an operation error and preventing the fire detector from being damaged by burning.

  Next, in the configuration of the heating tester 1, the battery power source 12 inside the main body 2 will be described in detail.

  The heating tester 1 includes a battery power source 12 for supplying power for driving them together with a heating unit 6 and a blowing unit 7 as an operating unit of the thermal fire detector D.

  As a result, the fire detector D is heated by the high-temperature wind using the heating element 6c as a heat source as a heat source. Therefore, the operation test of the fire detector D can be repeatedly performed at any timing without using a combustible material. it can. Moreover, since the electric wire which supplies electric power between the bracket 4 which supports the main body 2 from the outside and the inside of the main body 2 is not exposed, even if there is an obstacle around the fire detector D, The electric wire is not caught.

  Therefore, according to this heating tester 1, the operation test of the fire detector D can be repeatedly performed at any timing without using a combustible material, and an electric wire is connected to an obstacle around the fire detector D. It can be prevented from being caught.

  In the case of the present embodiment, as described above, the air blowing means 7 is provided on the side of the heating means 6 inside the main body 2. A printed circuit board 9 is also provided. And the heating means 6, the ventilation means 7, and the printed circuit board 9 provided side by side, and the ventilation path which is located under the heating means 6 and the ventilation means 7, and makes the ventilation means 7 and the heating means 6 communicate. A battery power source 12 is housed below 8.

  Thereby, members other than the battery power source 12 such as the heating unit 6, the air blowing unit 7 and the printed circuit board 9 can be concentrated in the space on the top side inside the main body 2, and the battery power source 12 below is stored. A large space can be ensured, and the capacity of the battery power source 12 can be increased.

The cover 2g and the battery lock member 2h cooperate with each other to constitute a mechanism in which the cover 2g cannot be closed unless the battery power supply lock member 2h is in a locked state to prevent the battery power supply 12 from dropping. Thus, the cover 2g cannot be closed unless the battery power source 12 is securely housed and fixed in the main body 2 by the battery power source lock member 2h, so that the battery power source 12 is imperfectly fixed and accidentally falls. To prevent that. That is, a foolproof mechanism is configured.

  The battery power source 12 can be, for example, a secondary battery such as a lithium ion battery, a nickel hydride storage battery, or a nickel cadmium battery, and can be a battery pack that houses an assembled battery of these secondary batteries. By using a battery pack, the battery power source 12 can be arbitrarily and easily replaced as necessary.

  For example, the heating means 6, the blowing means 7, and the battery power source 12 are housed in the main body 2, but the battery power source 12 is heated so that the electric power supply wire is not exposed to the outside from the main body 2. It is desirable that the means 6 and the blowing means 7 are connected to the inside of the main body 2. Further, the air blowing means 7 allows air to flow between the inner cylinder 6b and the outer cylinder 6a, thereby suppressing the heat of the inner cylinder 6b from being transmitted to the outer cylinder 6a, and heat radiation from the outer cylinder 6a to the inside of the main body 2 is suppressed. Although the thermal radiation suppression means to suppress is formed, it is not restricted to this, You may make it form a thermal radiation suppression means by another method. By providing such a heat radiation suppressing means, the mounting density inside the main body 2 can be increased, so that the blower means 7 can be provided above the main body 2 close to the side of the heating means 6. And by doing in this way, the space which accommodates the battery power supply 12 under the main body 2 can be formed. Moreover, although the opening 2f for attaching and detaching the battery power source 12 is provided at the bottom portion of the main body 2, it is not limited to this and may be provided at any position of the main body 2. At this time, the battery power supply lock member 2h constitutes a mechanism in which the cover 2g cannot be closed unless the battery power supply 12 is locked to prevent the battery power supply 12 from dropping off. Since the cover 2g cannot be closed unless it is securely housed and fixed, the battery power supply 12 is prevented from being incompletely fixed and accidentally falling off.

Further, the protrusion 3d provided on the outer periphery of the hood 3 may have a shape that is continuous in the circumferential direction so as to form a polygonal shape in a plan view. It is good also as what forms the shape notched in the shape. Further, the shock absorbing member 2c provided on the outer periphery of the main body 2 may be provided on the outer periphery of the bottom portion of the main body 2, or may have a frame shape along the outer periphery of the main body 2, or may be an elastomer or the like. It may be formed of an elastic body. The cylindrical portion 3a of the hood 3 may have an enlarged diameter upward, or may have a bellows structure that can contract in the vertical direction. Further, the hood 3 does not contact the mounting surface of the fire detector D to form a closed space, but is close to the fire detector D so as to cover at least the periphery of the detector of the fire detector D. May be. Further, the battery power source 12 may be a primary battery such as a dry battery instead of a secondary battery, or may be a plurality of batteries housed individually instead of an assembled battery, or a fuel cell. Good. Further, the battery power source 12 may be provided outside and connected by a cable without being stored inside the main body 2, or may be stored inside the support bar 5. Further, the heating element 6c is not limited to the coil-shaped winding, and may be wound in a plurality of layers of regular polygons, or may be a cylindrical heating element that does not use a heating wire. . Further, the blower means 7 uses a centrifugal fan having a blower outlet that deflects air sucked from the intake port at right angles and blows it out. However, the present invention is not limited to this, and an axial fan or the like that does not deflect the blowing direction. Other fans may be used. In addition, it is equipped with an indicator lamp that displays the status of the tester according to the operating status of the tester, including the status of output change by the output variable means, the output status, and the operating status of the proximity sensor. The tester may be able to easily grasp the operating status of the tester. Moreover, the indicator lamp which displays the said output condition, the operation condition of a proximity sensor, etc. is good also as what is used. Further, in order to vary the temperature or temperature rise of the high-temperature air that is blown out, the magnitude of the output to be supplied to the heating element 6c or the output increase rate is variable, but the voltage output to the heating element 6c may be variable, The rate of pulses output to the heating element 6c may be variable.
