Abstract

(57) [Abstract] [PROBLEMS] In an air filter device for a portable engine cutter that causes a lot of dust, it easily clogs, and nobody is affected at the work site without impairing the conventional filtering performance of the air filter. However, an air filter device for a portable engine cutter is obtained in which the air filter can be easily removed, cleaning or replacement can be performed in a short time, and interruption time of cutting work due to clogging of the filter can be shortened. SOLUTION: The first stage air filter nonwoven fabric and the second stage
Separate the filter paper type filter element of the air filter of the stage, cover the upper part of the filter box that delivered the filter paper type filter element with a wire mesh, cover it with a non-woven fabric, and attach it to the filter box so that it can be opened and closed freely The non-woven fabric is fixed by covering the cover with the air intake port, and when the air filter device is clogged, the non-woven fabric of the first-stage air filter that is easy to clean or replace can be easily attached and removed to shorten the cleaning time. Made possible.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention is a mobile phone used to cut the cast iron, concrete, stone material, etc. by transmitting the rotation of the engine to the cutter by interlocking the output shaft of the engine and the main shaft equipped with the disk-shaped cutter with an arbitrary driving means. Type engine cutter air filter device.

[0002]

[Prior art]

 Conventionally, as this type of air filter device, the nonwoven fabric (a) of the first stage air filter shown in FIG. 3 is installed outside the filter paper type filter element of the second stage air filter, and the nonwoven fabric ( It is known that a) and a filter paper type filter element (b) are fixed to a filter box (e) together with an upper lid (c) with a bolt (d).

[0003]

[Problems to be solved by the device]

 Since the engine cutter generates a lot of dust during the cutting work, the air filter immediately becomes clogged, and the engine speed drops, making it impossible to cut.Therefore, you must disassemble and clean the air filter device each time. However, with the technology described in the prior art, not only is disassembly troublesome, but the air filter cannot be cleaned at the work site, and it is often taken back to the maintenance shop. There was a problem that the rate became extremely poor.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to make it easy for anyone to use an air filter device without impairing the conventional filtering performance of the air filter device. The purpose of the present invention is to provide a filter device that can be removed and can be cleaned or replaced in a short time at the work site.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the air filter device of the present invention separates the nonwoven fabric of the first stage air filter and the filter paper type filter element of the second stage air filter, and the filter paper type filter element is an air filter box. Built-in, cover the upper surface of the air filter box with a wire mesh, cover it with the non-woven fabric of the first-stage air filter, press it with the edge of the lid that can be opened and closed by the hinge, and stop the lid with a stopper plate. The non-woven fabric is fixed to the upper surface of the air filter box, and the air filter box is sealed with the non-woven fabric to facilitate the installation and removal of the non-woven fabric of the first-stage air filter that is easy to clean or replace. The time required for cleaning is shortened.

[0006]

[Embodiment of device]

 Embodiments of the invention will be described with reference to the drawings. 1 and 2, the filter paper type filter element (1) of the second stage air filter has an upper part sealed with a filter element upper cover (3) and a lower part sealed with a filter element lower cover (4). A second-stage filter unit having an air filter chamber (5) is housed in the air filter box (2) and fixed to the bottom with bolts (14). The carburetor suction port (6) is connected by a ventilation pipe (7).

A seal frame (8) is installed like a lid on the upper part of the air filter box (2), and a wire net (9) is installed in the frame of the seal frame (8). Cover the non-woven fabric (10) of the first stage air filter on top, and clamp the entire circumference of the rim of the non-woven fabric (10) on the seal frame (8) with the edge frame of the lid (11) from above. The upper opening of the box (2) is sealed and fixed with a non-woven fabric (10) through a seal frame (8).

An air inlet (15) is opened in the lid (11), and the lid (11) is attached to the air filter box (2) by a hinge (12) so that the lid (11) can be opened and closed by a stopper plate (13). The air that has entered the air inlet (15) of the lid (11) is filtered by the non-woven fabric (10) of the first stage air filter and enters the air filter box (2). Furthermore, it is filtered by the filter paper type filter element (1) of the second stage air filter, enters the air filter chamber (5), and flows into the carburetor intake port (6) of the engine through the ventilation pipe (7). Has become.

[0009]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

In the air filter device of the portable engine cutter according to claim 1, the nonwoven fabric of the first stage air filter and the filter paper type filter element of the second stage air filter are separated, and the nonwoven fabric forms the hinge. Since the lid that opens and closes easily as a rotating shaft only presses the peripheral edge to fix it, if a clogging occurs, open the lid on the spot and remove the non-woven fabric. Since the filter is completely cleaned by closing the lid on the air filter, the filtration performance of the conventional filter is not impaired, and it becomes an air filter that anyone can easily clean in the work place in a short time, often causing clogging. Even so, the work interruption time for cleaning is reduced and the cutting work efficiency by the engine cutter is improved.

In the air filter device of the portable engine cutter according to the second aspect, when a towel cloth is used for the first stage air filter, not only cleaning is easier than non-woven cloth, but also inexpensive and good in marketability. Therefore, it is not difficult to replace the towel cloth, and the air filter device can be cleaned in a shorter time.

In the air filter device of the portable engine cutter according to claim 3, when tissue paper is used for the first stage air filter, it becomes a throwaway filter, and cleaning is completed only by replacing the tissue paper. However, the air filter device can be cleaned in a shorter time.
