Problems solved by technology

[0002] The air filter is a part that will be installed on the internal combustion engine. There is usually a filter element inside the air filter, and the filter element needs to be cleaned or replaced after a period of use. Therefore, the air filter is usually detachable, that is, the air filter cover and the air filter. The filter bases are detachably connected. At present, most of the detachable methods between the air filter cover and the air filter base are buckled, or screw fastened, or multi-turn screwed. There are problems that the disassembly and assembly are not fast enough and the operation is not convenient enough.

Embodiment 1

[0029] Such as Figure 1 to Figure 6 As shown, a quick dismountable air filter, the air filter is integrally installed on the internal combustion engine 5, the air filter includes an air filter base 1 and an air filter cover 2 installed on the air filter base 1, and the air filter also includes a lock A tightening rod 3 and a locking knob 4, the locking rod 3 is arranged on the air filter base 1, the locking rod 3 is fixedly connected with the air filter base 1, the locking knob 4 and the locking rod 3 The air filter cover 2 is clamped between the locking knob 4 and the locking rod 3 when the locking knob 4 and the locking rod 3 are fastened together.

[0030] The locking rod 3 includes a rod body 31 and a locking ring 32 formed radially extending from the rod body 31. There may be multiple locking rings 32, or one locking ring 32, preferably two in this embodiment. The knob 4 is provided with a gap 401 matching the locking knob 32 , and the locking knob 4 is provided with a ...

Embodiment 2

[0044] The difference between this embodiment and Embodiment 1 is that in this embodiment, the second guide surface is set on the transition protrusion, specifically, it is set between the top surface of the transition protrusion and the bottom surface of the positioning groove, similar to the first guide surface. The guide surface, but the second guide surface is steeper than the first guide surface. Of course, in this embodiment, the locking part can still remain a cylinder, or it can be a non-cylindrical body.

Abstract

The invention discloses an air filter capable of quick assembly and disassembly, and belongs to the field of garden tool internal-combustion engines. The air filter includes an air filter base and anair filter cover installed on the air filter base; the air filter further includes a locking rod and a locking knob, the locking rod is arranged on the air filter base, the air filter cover is clampedbetween the locking knob and the locking rod, the locking knob and the locking rod are connected through relative rotating and fastening, the locking rod includes a rod body and a locking bolt formedby radial extension of the rod body, the locking knob is provided with a gap matched with the locking bolt, and a positioning groove for positioning the locking bolt is formed in the locking knob inthe circumferential direction of the gap. The air filter has the advantage that the air filter cover can achieve quick assembly and disassembly.

Description

【Technical field】 [0001] The invention relates to a quick dismountable air filter, which belongs to the field of internal combustion engines of garden tools. 【Background technique】 [0002] The air filter is a part that will be installed on the internal combustion engine. There is usually a filter element inside the air filter, and the filter element needs to be cleaned or replaced after a period of use. Therefore, the air filter is usually detachable, that is, the air filter cover and the air filter. The filter bases are detachably connected. At present, most of the detachable methods between the air filter cover and the air filter base are in the form of buckles, or screw fastening, or multi-turn screwing. Both methods have the problems of fast disassembly and assembly and insufficient operation convenience. 【Content of invention】 [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a quick dis...
