Description

TECHNICAL FIELD

[0001] The utility model relates to an air conditioner filter screen, especially an air conditioner filter screen convenient to disassemble. BACKGROUND

[0002] In the current air conditioning system, the filter screen as one of the key components undertakes the important task of filtering dust, pollen, bacteria and other impurities in the air to ensure the freshness and health of indoor air. These filter screens are usually designed to be detachable to facilitate regular cleaning or replacement by users, thereby maintaining their filtering efficiency and prolonging the service life of the air conditioner. However, in many air conditioner models, the fixing method of the filter screen relies on a series of ingenious buckle systems. These buckles, as a bridge connecting the filter screen and the air conditioner body, not only need to securely lock the filter screen to prevent its displacement during operation, but also need to consider the principle of easy user operation to achieve quick installation and disassembly. However, this design that balances stability and convenience has brought some inconvenience in certain situations.

[0003] When users clean and maintain the filter screen and try to remove it from the air conditioner body, they often encounter the following problem: due to the long-term use and multiple disassembly and assembly of the buckle, its elasticity may become more sensitive. In the moment of unfastening the buckle and pulling out the filter screen, the elastic restoring force of the buckle may suddenly release, causing the dust, dirt, and even tiny particulate matter originally attached to the surface of the filter screen to be suddenly blown up, forming a short-lived "dust storm". If the indoor ventilation conditions are poor or the user fails to take timely measures (such as wearing a mask, closing nearby doors and windows, etc.), these accidentally raised pollutants may quickly spread throughout the room, not only polluting the air that has been purified by the filter screen, but also causing secondary pollution to the indoor environment, affecting the health and comfort of the occupants. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide an air conditioner filter screen convenient to disassemble.

[0005] The technical scheme adopted by the utility model to solve the above technical problem is as follows: an air conditioner filter screen convenient to disassemble, comprising an air conditioner filter screen, a knob, a gear, a rack, a connecting plate, and a clamping block.

The connecting plate is centrally symmetrically and slidably connected in the slot. A rack is arranged on the opposite end of the connecting plate. The rack and the gear are intermeshed. The clamping block is fixed to the end of the connecting plate away from the rack. The clamping block can block the slot. The clamping block can be embedded with the buckle of the air conditioner body.

[0006] A more excellent preferred scheme of the utility model is that the slot has a through hole at both ends, and the through hole corresponds to the buckle of the air conditioner body.

[0007] The utility model discloses more excellent one kind for a preferred scheme is also including pull rope, and pull rope is symmetrically arranged in air conditioner filter screen bottom.
