[0002] An air filter is a device used to purify air. An air filter consists of two parts: a filter element and a housing. The main requirements for an air filter are high filtration efficiency, low flow resistance, and the ability to operate continuously for extended periods without maintenance.

[0003] Existing air filters can generally meet normal usage needs. However, while they can be used continuously for extended periods without maintenance, this does not mean they require no maintenance at all. Currently, the housing of air filters typically consists of two parts fixed together with screws. The air inlet and outlet of the housing are also usually connected to the inlet cap and outlet pipe with bolts, making disassembly and maintenance relatively inconvenient. Therefore, this invention provides an air filter that is easier to maintain. Utility Model Content

[0004] The technical problem solved by this utility model is that the outer shell is composed of two parts that are fixed together with screws, and the air inlet and air outlet of the shell are connected to other components with bolts, which makes it relatively inconvenient to disassemble and maintain the air filter.

[0005] To solve the technical problem, the technical solution provided by this utility model is as follows: an air filter that is easy to maintain, comprising an air filter body, the air filter body including an air filter cylinder, the air filter cylinder containing a filter element; the air filter cylinder including a left large body and a right small body, the left large body having a plurality of locking fasteners around its circumference for locking the right small body; an air inlet cap detachably connected to the top air inlet of the air filter cylinder; a transition hose one detachably connected to the air outlet of the air filter cylinder, the end of the transition hose one having a connecting pipe, and the end of the connecting pipe having a transition hose two.

[0006] Furthermore, the right sidewall near the left sidewall has a locking groove that mates with the locking mechanism.

[0007] Furthermore, a support frame is provided at the bottom of the air filter housing, and the support frame is fixedly connected to the air filter housing by bolts.

[0008] Furthermore, a rubber gasket is provided between the air inlet cap and the top air inlet of the air filter body, and the air inlet cap is fixedly connected to the top air inlet of the air filter body by a stainless steel hose clamp.

[0009] Furthermore, the connecting pipe is made of stainless steel, and the first and second transition hoses are made of EPDM material.

[0010] Furthermore, the air outlet of the air filter body is fixedly connected to the first transition hose, the first transition hose to the connecting pipe, and the connecting pipe to the second transition hose by T-shaped spring clamps.

[0011] Furthermore, a blockage alarm is provided on the connecting pipe.

[0012] The beneficial effects of this utility model are:

[0013] By prying the locking fastener out of the locking slot, the right smaller body can be removed from the left larger body, making it easier to replace and clean the filter element inside the air filter housing, thus facilitating maintenance. The intake cap can be easily removed and installed by tightening and loosening the stainless steel hose clamp, and the transition hose one, connecting hose, and transition hose two can be easily removed and installed by tightening and loosening the T-type spring clamp, thus facilitating maintenance personnel to maintain the air filter.
