Abstract

The invention discloses a nozzle of a bladeless fan, belonging to the technical field of fans. The nozzle comprises an annular shell and an adjusting ring; the shell is internally provided with a channel; the shell is also provided with a gap which is communicated with the channel; the top surface of the gap is at least provided with a part of cylindrical surface; the outer ring of the adjusting ring is matched with the cylindrical surface, and the inner ring of the adjusting ring decreases gradually along the direction of air exhaust; when the adjusting ring is shifted to penetrate into the gap, the width at the opening of the gap decreases gradually, namely the area of air exhaust decreases, and at the time, the intensity of air exhaust is improved gradually; when the adjusting ring is shifted to be pulled out of the gap, the width at the opening of the gap increases gradually, namely the area of air exhaust increases, and at the time, the intensity of air exhaust decreases gradually. Therefore, different air exhaust intensity can be obtained through changing the positions of the adjusting ring, and requirements of different occasions and different requirements of individuals can be met.

Description

The nozzle of on-bladed fan

Technical field

The invention belongs to the fan technical field, a kind of specifically nozzle of on-bladed fan.

Background technique

Number of patent application: 200810177844.8 disclose a kind of on-bladed fan, and the on-bladed fan comprises nozzle and is used to produce the member through the air-flow of nozzle.Referring to Fig. 1 to Fig. 3, nozzle is the housing 1 of a circle annular, and housing 1 set inside has passage 11, also is provided with the slit 3 that a circle communicates with passage 11 on the housing 1, and the opening 31 in slit 3 is exhaust outlet.During use, air-flow feeds in the housing 1, in the inlet passage 11, discharges via exhaust outlet again.

The nozzle of this form, the width of the opening in slit is fixed, and people can't regulate the intensity of air-out, therefore can't satisfy the needs and the individual different demands of different occasions.

Summary of the invention

The present invention is directed to deficiency of the prior art, a kind of nozzle of on-bladed fan is provided, can regulate the intensity of air-out.

In order to solve the problems of the technologies described above, the present invention is able to solve through following technical proposals: the nozzle of on-bladed fan comprises the annular housing of a circle; Said enclosure interior is provided with passage; Also be provided with the slit that a circle communicates with said passage on the said housing, the end face in said slit has at least a part to be the cylndrical surface, also comprises an adjustment ring; Match with said cylndrical surface in the outer ring of said adjustment ring, and the inner ring diameter of said adjustment ring diminishes along the direction of air-out gradually.When mobile adjustment hoop slit was goed deep into, the width of the opening in slit diminished gradually, i.e. the area of air-out diminishes, and the intensity of air-out at this moment just improves gradually.When outside moving adjustment hoop slit, pulling out, the width of the opening in slit becomes greatly gradually, i.e. it is big that the area of air-out becomes, and the intensity of air-out at this moment just reduces gradually.Therefore can obtain the different monsoon intensities that goes out through the position of conversion regulating ring, satisfy the needs and the individual different demands of different occasions.

In the technique scheme, preferred, be provided with the block that limits the said slit of said adjustment hoop medial movement in the said slit.Increase after the block, prevent to cause the adjustment ring to take out in the adjustment ring inlet passage.

In the technique scheme, wherein a kind ofly adjust being shaped as of ring, the shape of cross section of said adjustment ring is a triangle, and a said leg-of-mutton acute angle gos deep in the said slit.

In the technique scheme, a kind ofly in addition adjust being shaped as of ring, the shape of cross section of said adjustment ring is trapezoidal.

The invention has the beneficial effects as follows: when mobile adjustment hoop slit was goed deep into, the width of the opening in slit diminished gradually, i.e. the area of air-out diminishes, and the intensity of air-out at this moment just improves gradually.When outside moving adjustment hoop slit, pulling out, the width of the opening in slit becomes greatly gradually, i.e. it is big that the area of air-out becomes, and the intensity of air-out at this moment just reduces gradually.Therefore can obtain the different monsoon intensities that goes out through the position of conversion regulating ring, satisfy the needs and the individual different demands of different occasions.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

Embodiment 1, referring to Fig. 4 and Fig. 5, and the nozzle of on-bladed fan; The housing 1 and adjustment ring 4 that comprise a circle annular; Housing 1 set inside has passage 11, and the bottom of housing 1 forms lug boss 2, forms the intake grill 21 that communicates with passage 11 in the lug boss 2; Form the slit 3 that a circle communicates with passage 11 on housing 1 inner ring, the end face and the bottom surface that constitute slit 3 are all the cylndrical surface.Form block 5 on the end face in slit 3, the shape of cross section of adjustment ring 4 is a right-angled triangle, matches with the end face in slit 3 in the outer ring 41 of adjustment ring 4, and a less acute angle of right-angled triangle gos deep in the slit 3.These inner ring 42 diameters that just guaranteed adjustment ring 4 diminish along a side of air-out gradually.

During use, referring to Fig. 5, when being moved to the left adjustment ring 4, the width of the opening 31 in slit 3 constantly diminishes, and the intensity of air-out at this moment will raise gradually.When the adjustment that moves right encircled 4, it is big that the width of the opening 31 in slit 3 constantly becomes, and the intensity of air-out at this moment will reduce gradually.In the moving process, block 5 is used to limit the position of adjustment ring 4, prevents that adjustment from encircling 4 and falling in the passage 11.Block 5 can be arranged to arbitrary shape, also can be arranged on the bottom surface in slit 3, as long as it is just passable to prop up adjustment ring 4.

Embodiment 2, and referring to Fig. 6, the shape of cross section of adjustment ring 4 is trapezoidal, and all the other are with embodiment 1.

Embodiment 3, and referring to Fig. 7, the inner ring 42 of adjustment ring 4 is shaped as arc surface, and all the other are with embodiment 1.
