Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a removable filter device for air conditioning purification. Background Technology

[0002] Air purification systems in industries such as medical, electronics, and food require extremely high air cleanliness, and their filtration devices must effectively intercept pollutants such as dust, microorganisms, and insects. Traditional filtration devices mostly use fixed filter structures, which present the following technical challenges:

[0003] 1. Low maintenance efficiency: Replacing the filter requires removing bolts or clips, which is cumbersome and relies on special tools, especially in confined spaces or high-frequency maintenance scenarios, where it is time-consuming.

[0004] 2. Lack of clogging monitoring: The degree of filter clogging relies on regular manual inspection, which cannot detect changes in resistance in real time, easily leading to insufficient air supply or increased energy consumption;

[0005] 3. Insufficient reliability of quick-release structure: Some improved filters adopt simple sliding rails or magnetic quick-release designs, but the locking force is insufficient, and they are prone to air leakage or displacement under high pressure differential, affecting the sealing performance; therefore, we propose a removable filter device for air purification air conditioners to solve this problem. Utility Model Content

[0009] At least two sets of positioning mechanisms are connected to both the front and rear sides of the mounting frame.

An octagonal hole is opened on one side of the connecting plate, and the octagonal prism is movably inserted into the octagonal hole. The rotating plate is rotatably sleeved on the outside of the fixed column, and the rotating plate movably abuts against the outside of the filter housing.

[0010] Preferably, the fixed plate is movably abutted against the outside of the rotating plate, and two guide posts are fixedly installed on one side of the rotating plate, with the connecting plate slidably sleeved on the outside of the two guide posts.

[0011] Preferably, a compression spring is fixedly connected to the other end of the guide post, and the other end of the compression spring is fixedly connected to the connecting plate.

[0012] Preferably, a square frame is fixedly installed on the outer side of the insect-proof net, the square frame is slidably connected within the mounting frame, and the square frame is movably abutted against the other end of the pressure sensor.

[0013] Preferably, a connecting spring is fixedly connected to one side of the frame, and the other end of the connecting spring is fixedly connected to the inner wall of the mounting frame.

[0014] Preferably, both ends of the filter housing are integrally formed with square extensions, and one side of the square extensions is provided with multiple assembly holes.

[0015] In this utility model, the air-conditioning pull-out filter device restricts the forward and backward movement of the mounting frame by the contact between the rotating plate and the filter housing, locks the rotation of the rotating plate by the cooperation of the octagonal prism and the octagonal hole on the connecting plate, blocks insects by the insect screen during the ventilation process of the filter housing, assists in the positioning of the insect screen by the connecting spring, and monitors the filtration resistance of the insect screen by the pressure sensor.

[0016] In this utility model, a removable filter device for air conditioning purification can pull the connecting plate when the resistance reaches a preset value, so that the octagonal prism can be dislodged from the octagonal hole. Then, the connecting plate is rotated, and through cooperation with the guide column, the rotating plate is rotated, so that the rotating plate is released from the fixing of the mounting frame. Then the housing pulls the mounting frame out of the filter housing for easy cleaning.
