Description

[Detailed description of the invention] The present invention is an air cleaner that includes a main body case that is connected to the inlet of a vaporizer and houses a filter therein, and a lid case that covers and engages the opening of the main body case. This is related to.

Conventionally, in this type of air cleaner, the filter is pressed and sandwiched between the lid case and the main body case, but the outer periphery of the filter engages with the inner wall of the main body case. Since a gap is formed between the filter and the outer periphery, and the intake air passes through this gap, there is a drawback that the intake air cannot be completely filtered by the filter.

In this invention, the inner wall of the main body case with which the outer periphery of the filter engages is inclined inward in the direction in which the lid case presses, so that when the filter is pressed with the lid case, the outer periphery of the filter is The purpose of the filter is to bring it into close contact with the inner wall of the case to ensure complete filtration.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

In the figure, 1 is an air cleaner, which is constructed as follows. That is, 2 is connected to the suction port 4 of the vaporizer 3, and there is a spongy filter 5 inside.
7 is a lid case that engages with the main case 2 and covers the opening 9 of the main case 2. 11 is a communication hole provided in the main body case 2;
It communicates with the suction port 4. Reference numeral 13 denotes an intake chamber communicating with the communication hole 11 and partitioned by support plates 15, 15, 15. A partition plate 17 faces the communication hole 11 at an appropriate distance, and is fixed to the inner ends of the support plates 15, 15, . . . . Reference numeral 19 denotes a support post projecting from the inner surface of the lid case 7, which presses and holds the filter 5 between the support plate 15 and the partition plate 17. 2
1 is a main body case 2 with which the outer periphery of the filter 5 engages.
The lid case 7 is provided on the inner wall thereof so as to be inclined inward in the direction in which the filter 5 is pressed. 2
3 is the inner wall 2 of the main body case 2 on the inside of the lid case 7.
1 and a supporting wall that protrudes at an appropriate interval.
25 is an intake hole opened on the outer surface of the lid case 7; 27
is a bolt for fixing the lid case 7 and the main body case 2 to the suction port 4 of the carburetor 3.

In the above embodiment, the atmosphere is taken in through the intake holes 25, 25, . . .
It passes through the air intake chamber 13 and is sucked into the intake port 4 of the vaporizer 3 from the communication hole 11. When assembling this air cleaner 1, insert the filter 5 into the main body case 2, engage the lid case 7, and tighten both bolts 27, 27 to the intake port 4 of the carburetor 3. is the partition plate 1 by the pillars 19, 19,...
7. The filter 5 is pressed and held between the support plates 15, 15, . . . and the outer periphery is pressed against the inclined inner wall 21 by the support wall 23, so that no gap is formed on the outer periphery of the filter 5.

Since the present invention has the configuration as described in the claims, there is no gap between the outer periphery of the filter and the inner wall of the main body case, so that air does not pass through from the outer periphery of the filter. The filter can perform complete filtration.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be implemented in other embodiments as well. Further, the symbols shown in the claims do not limit the technical scope of the present invention.
