Abstract

The invention discloses an air filter for an internal combustion engine. The housing cover is provided with a mounting hole, wherein a handle shaft is rotatably installed; The handle of the mounting hole and the fixing block; the air filter seat is provided with fixing holes, and the fixing holes are adapted to the cross-sectional shape of the fixing block and are all eccentric shapes. On the one hand, the relative position of the air filter seat and the housing cover can be locked, so that the housing cover and the air filter seat can be combined stably and reliably to avoid vibration; on the other hand, in the During the whole process of dismounting and assembling the casing cover and the air filter seat, the handle will not be separated from the casing cover, which can reliably prevent the handle from being lost. The product structure is simple, the operation is convenient, and the cost is relatively low. The invention also discloses an internal combustion engine and a generator comprising the above-mentioned air filter, and has corresponding technical effects.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to an air filter. The invention also relates to an internal combustion engine and an internal combustion engine driven generator. Background technique [0002] The housing cover and the seat body of the small internal combustion engine air filter can be connected by bolts or steel wire buckles. The air filter connected by bolts requires a long operation time when the housing cover needs to be removed, and the operation is inconvenient. After disassembly, the bolts are also easy. Shedding lost. The structure of the air filter connected by buckle is relatively complicated, and the cost is also relatively high. [0003] Therefore, it is necessary to design an air filter connection method that is simple in structure, easy to disassemble, prevents detachment, and has high cost performance. Contents of the invention [0004] The object of the present invention is ...
