Description

Technical Field

[0001] This utility model relates to the field of automotive filters, specifically to a structure for an automotive air filter. Background Technology

[0002] An air filter is a type of filter, also called an air cartridge, air purifier, or filter element. It is mainly used for air filtration in engineering vehicles, automobiles, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms. For example, patent number CN212838122 U provides an automatic air filter cleaner for automobiles, which includes an air filter with an internal ventilation chamber. A partition is fixedly connected between the top of both sides of the inner wall of the ventilation chamber. A miniature vibration motor is installed on the top of the partition, and both sides of the miniature vibration motor are in contact with the inner wall of the ventilation chamber through connecting structures. A fixing component is fixedly connected to one side of the bottom of the inner wall of the ventilation chamber, and a fan plate is rotatably connected inside the fixing component via a rotating shaft. However, this patent does not specify how to quickly install and remove the air filter. Utility Model Content

[0003] The purpose of this invention is to provide an automotive air filter structure that solves the problem of how to quickly install and remove the air filter.

[0004] To achieve the above objectives, this utility model provides an automotive air filter structure, comprising a housing, a fixing plate disposed within the housing, a guide rod disposed on the fixing plate, sliders slidably disposed at both ends of the guide rod, a support plate slidably disposed on the fixing plate, one end of a hinge rod hinged to the support plate and the other end hinged to the slider, a spring disposed on the guide rod, one end of the spring connected to the fixing plate and the other end connected to the slider, a filter element disposed on the support plate, and a cover plate detachably disposed on the housing, the cover plate abutting against the filter element.

[0005] Preferably, a limit rod is slidably provided on the fixed plate, and the limit rod is connected to the support plate.

[0006] Preferably, the cover plate is provided with a locking block, the housing is provided with a locking groove, and the locking block is movably disposed in the locking groove.

[0007] Preferably, the cover plate is provided with bolts, and the bolts at least partially pass through the housing.

[0008] Preferably, the cover plate is provided with a first hole, and the housing is provided with a second hole. The bolt passes through the first hole and the second hole in sequence to fix the cover plate to the housing.

[0009] Preferably, the cover plate is provided with a throttle handle.

[0010] This utility model provides an automotive air filter structure, which includes a housing, a fixed plate inside the housing, a guide rod on the fixed plate, sliders slidably mounted at both ends of the guide rod, a support plate slidably mounted on the fixed plate, a hinge rod with one end hinged to the support plate and the other end hinged to the slider, a spring on the guide rod with one end connected to the fixed plate and the other end connected to the slider, and a filter element mounted on the support plate. A cover plate is detachably mounted on the housing, and the cover plate abuts against the filter element. When using the device, the filter element is first placed on the support plate, then the handle on the cover plate is rotated, causing the cover plate to move in a locking groove on the housing, aligning the first hole and the second hole. A bolt is then passed through the first and second holes. When replacing the filter element, the bolt is rotated, the cover plate is removed, and the filter element is displaced by the sliders on the guide rod moving the support plate upwards. This simple structure facilitates easy disassembly and installation of the filter element.

[0011] Beneficial effects: By rotating the handle on the cover plate, the cover plate moves the locking block in the locking groove on the housing, causing the first hole and the second hole to align. Then, the bolt passes through the first and second holes. When replacing the filter element, rotating the bolt removes the cover plate. The filter element is then displaced by the slider on the guide rod moving the support plate upwards, thus facilitating the removal and installation of the filter element.

[0012] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description
