Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an air cleaner element for a two-cycle engine mounted on a brush cutter and other air cleaner elements applied to a carburetor of various internal combustion engines. is there.

(Prior Art) A conventional example of the air cleaner element will be described with reference to FIGS. 5 and 6. As shown in FIG. 5, a polyurethane sheet (open-celled material) (10) is punched into a ring shape by press working and directly It has a ring-shaped cylindrical air cleaner element (11) inside the cleaner body (15) attached to the carburetor (13) with screws (14) etc. as shown in FIG. The air cleaner element (11) is placed on the cleaner cover (16), and the air cleaner element (11) is sandwiched between the cleaner body (15) and the cleaner cover (16) and the pin ( The inner peripheral side is supported by the group (17), and the air (a) passes through the cleaner body (1
It flows in from the lower hole (15a) of 5), permeates the air cleaner element (11) and is cleaned, and as shown by the arrow, the carburetor (13)
Be introduced to.

(Problems to be Solved by the Invention) Since the conventional air cleaner element is directly punched and formed in a ring shape from a polyurethane sheet as shown in FIG. 5, a large amount of waste parts (10a) (10b) is formed on the polyurethane sheet. ) Is made, and the cost is significantly high, and it is formed in a ring shape and is large and bulky, and the whole surface comes into contact with the outside air, dust and the like are easily attached before use and are easily scratched, which is a cause of performance and quality deterioration. However, there are problems such as the need to pay attention to packaging and storage.

The present invention was developed to address the above-mentioned problems, and the purpose of the present invention is to significantly reduce the size and cost of the material and to reduce the size and size of the packaging. The purpose of the present invention is to provide an air cleaner element which has improved storage and handling performance, prevents adhesion and damage of dust and the like, and has improved cleaning performance and reliability by being inverted.

(Means for Solving the Problem) The present invention is an air cleaner element made of a continuous foam material applied to a vaporizer or the like of an internal combustion engine, in which semicircular portions are provided at both ends to form a substantially rectangular shape. The element main body is characterized in that it has a structure in which a slit that is inverted at the center of the element main body and expands in a ring shape is installed vertically while leaving both the semicircular shaped portions, and the element main body has a substantially rectangular shape. By forming a slit vertically in the center, the shape can be significantly downsized and compacted to facilitate packaging, storage and handling, to prevent dust from adhering and damaging, and to reverse the slit for slitting. The surface is formed in the air inflow part to obtain cleanliness and reliability.

(Function) The element main body is formed in a substantially rectangular shape by providing semicircular portions at both ends, and the slit that is inverted to the center of the element main portion and expands in a ring shape is left on both semicircular portions. Since it is installed vertically, the shape is significantly smaller and compact, the material is greatly saved, the packaging, storage and handling are easy, and there is almost no contact with the outside air and no damage occurs. The slit surface is effectively prevented and expanded in a ring shape by reversing, and the slit surface is newly brought into contact with the outside air to serve as an inflow surface of air, and air permeation and cleaning are improved.

(Embodiment) One embodiment of the present invention is shown in FIG. 1 to FIG.
(1) is an element main body made of an open-celled material such as polyurethane, (2) is a semicircular portion provided at both ends of the element main body (1), (3) is the center of the element main body (1) A slit vertically installed in the section, in an air cleaner element made of a continuous foam material applied to a carburetor of an internal combustion engine,
It has an element main body (1) formed in a substantially rectangular shape by providing semicircular portions (2) (2) at both ends, and the element main body (1)
An air cleaner element is formed by vertically arranging a slit (3) which is inverted to the center of the and expands in a ring shape, leaving both semicircular portions (2) and (2).

As shown in FIG. 2, the air cleaner element is formed by punching from a polyurethane sheet (a continuous cell sheet) (10) by press working, and a slit (3).
Element main part formed by punching
(1) is a semi-circular part (2) (2) at both ends as shown in FIG.
Since it is formed into a substantially rectangular shape by providing the above, the wasteful portion of the polyurethane sheet (10) as shown in the figure is significantly reduced, and the polyurethane sheet (10) is efficiently formed to significantly reduce the cost.

As shown in FIG. 1, the air cleaner element of the embodiment is substantially rectangular in size and compact, and the inside of the slit (3) is not in contact with the outside air. Since they are packaged in contact with each other, the upper and lower surfaces and the left and right surfaces are stored without being exposed to the outside air before use, the adhesion and damage of dust etc. are significantly reduced, the quality is significantly improved, and the packaging cost is reduced. It is easy to store and handle.

When applied to an air cleaner, if the slit (3) part is enlarged a little and inverted in the direction of the arrow as shown in Fig. 3, both semi-circular shaped parts provided at both ends as shown in the right figure. (2) (2) becomes the inner protrusion (2 ') (2'), and the element main body (1) is expanded due to the expandability of both inner protrusions (2 ') (2') due to the outward biasing force. A ring-shaped slit surface (3a) (3a) formed by the slit (3) becomes a new outer peripheral surface, and the outer surface of the element main body (1) is the inner peripheral surface (1a) (1a).
Becomes

The air cleaner element expanded in a ring shape by reversing the slit (3) part has no protrusion on the outer peripheral side and is easily arranged in the cleaner body (15) as shown in FIG. Covered by
The inner peripheral side is supported and stabilized by the group of pins (17), and the air (a) flows into the cleaner body (16) through the lower hole (15a) and permeates through the air cleaner element through the slit surface (3a). It is cleaned and supplied to the internal combustion engine.

When the air cleaner element is applied to the cleaner, the air cleaner element is turned over to become a penetration surface for air (a).
Since a) and (3a) are exposed to the outside air for the first time, damage is effectively prevented, and excellent cleaning performance and reliability can be obtained even in a narrow air passage with no protrusions on the outer peripheral side.

(Effects of the Invention) The present invention has the above-described structure, has an element main body formed in a substantially rectangular shape with semicircular portions at both ends, and is inverted to the central portion of the element main body. Since the slit that expands in a ring shape is installed vertically with both semi-circular parts left, the material is greatly saved and the cost is reduced, and the size and size are greatly reduced.
It is easy to handle, and dust and dirt are prevented from adhering to the outer surface, damage is prevented, and the slit surface that comes into contact with the outside air during reversal use becomes the air inflow surface, significantly improving cleaning performance and reliability. Has been done.
