Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to an automobile air filter with an improved structure. Background Art

[0002] Air filters are mainly used in pneumatic machinery, internal combustion machinery and other fields. Their function is to provide clean air for these mechanical equipment to prevent them from inhaling air with impurities and particles during operation, which increases the probability of abrasion and damage. The main components of an air filter are the filter element and the housing. The filter element is the main filtering part, which is responsible for filtering the gas, while the housing is the external structure that provides necessary protection for the filter element.

[0003] In the prior art, in order to improve the filtering effect and reduce the frequency of filter element replacement, a honeycomb plate and a main filter plate are arranged inside the casing, and the air passes through the honeycomb plate, the main filter plate and then the filter element for filtering. The honeycomb plate and the main filter plate can be removed for cleaning, and the honeycomb plate can also ensure the air intake, and can still ensure smooth air intake after some through holes are blocked. However, too much dust accumulates inside the honeycomb plate, resulting in congestion. After the honeycomb holes are too congested, the air intake will still be affected, resulting in a high frequency of removal and cleaning. Utility Model Content

[0022] Specifically, when the air intake fan is started, the motor 21 is started, and the single-groove pulleys 24 on the front and rear sides are driven to rotate through the double-groove pulley 22 and the transmission belt 23, thereby driving the front and rear drive shafts 25 to rotate, and the eccentric wheels 26 evenly distributed on the outer periphery of the front and rear drive shafts 25 continuously strike the honeycomb panel 14, causing the honeycomb panel 14 to vibrate, and the dust remaining in the honeycomb tube 15 is knocked into the inner lower ash discharge port 12 of the primary filter bin 11, and the round cover 13 is removed regularly to discharge the dust, and a knocking mechanism 2 is provided inside the secondary filter bin 3 to knock the honeycomb panel 14 inside the primary filter bin 11, thereby preventing a large amount of dust from accumulating inside the honeycomb tube 15, resulting in poor air intake for the engine.

[0023] In this embodiment, a main filter plate 4 is fixedly installed on the inner left side of the secondary filter bin 3, a tertiary filter bin 5 is fixedly connected to the left end of the secondary filter bin 3, a filter element 6 is fixedly installed inside the tertiary filter bin 5, the right end periphery of the filter element 6 is in contact with the left periphery of the secondary filter bin 3, the primary filter mechanism 1 includes a primary filter bin 11, an ash discharge port 12 is provided in the lower end opening of the primary filter bin 11, a round cover 13 is threadedly connected to the lower end of the ash discharge port 12, a honeycomb panel 14 is fixedly connected to the inner left side of the primary filter bin 11, honeycomb tubes 15 are evenly distributed on the right end of the honeycomb panel 14, and filter screens 16 are fixedly connected to the inner left side of the honeycomb tubes 15.
