[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4As shown, an air filter for a DC dehumidifier and heat exchanger includes a mounting frame 1, which is fixed to the outer wall of the filter body 2. A placement groove 3 is provided on the front side of the mounting frame 1, and two strip grooves 4 are provided on the front side of the mounting frame 1, communicating with the placement groove 3. L-shaped grooves 5 are provided on both the top and bottom surfaces of the inner wall of the placement groove 3, extending into the strip grooves 4. A mounting bracket 6 is slidably mounted on the inner wall of the placement groove 3, and limiting hemispheres 7 are fixed to the top and bottom surfaces of the mounting bracket 6. The limiting hemisphere 7 is slidably connected in the L-shaped groove 5. The mounting bracket 6 is slidably connected to the strip groove 4. A cleaning strip 8 is slidably provided on the inner wall of the mounting bracket 6. The cleaning strip 8 has an inclined surface. The cleaning strip 8 is in contact with the filter body 2. Two connecting posts 9 are fixed on the cleaning strip 8. A spring body 10 is fixed to one end of the connecting post 9. Two fixing grooves 11 are provided on the inner wall of the mounting bracket 6. The connecting post 9 is slidably inserted into the fixing groove 11. The other end of the spring body 10 is fixed to the inner wall of the fixing groove 11.

[0022] During use, when cleaning the filter body 2, the operator should first pull the mounting bracket 6 outward. The limiting hemisphere 7 will slide on the inner wall of the L-shaped groove 5 and continue to slide to the turning point of the L-shaped groove 5. Then, move the mounting bracket 6 to the right. Due to the existence of the inclined surface, the cleaning strip 8 will drive the connecting column 9 and the spring body 10 to retract into the fixing groove 11 under its action. As the mounting bracket 6 continues to move, the cleaning strip 8, with the help of the elastic potential energy of the spring body 10, makes its cleaning surface fit tightly against the filter body 2. The tight fit ensures the cleaning effect, thereby achieving efficient cleaning of the filter body 2.

[0023] It should be noted that the mounting bracket 6 and the mounting frame 1 are on the same plane and are hidden in the placement groove 3, which can effectively save installation space;

[0024] With the cooperation of the mounting bracket 6 and the cleaning strip 8, staff can easily clean the surface of the filter body 2, keeping the surface of the filter body 2 clean and effectively preventing dust, floating objects and other substances in the air from clogging the filter body 2, thus ensuring the working efficiency of the filter body 2.

[0025] like Figures 1-4 As shown, a spring plate 12 is fixed to the inner wall of the placement groove 3. The spring plate 12 is in contact with the mounting frame 6. A groove 13 is provided on the inner wall of the placement groove 3. Two fixing seats 14 are fixed on the top and bottom surfaces of the mounting frame 1. Fixing bolts 15 are threadedly connected to the inner wall of the fixing seat 14. An activated carbon adsorption layer is provided inside the filter screen body 2.

[0026] During use, the spring plate 12 uses elastic pressure to limit and fix the mounting bracket 6 within the placement groove 3, effectively preventing the mounting bracket 6 from falling out of the groove 3 and ensuring the stability of the mounting bracket 6 when placed. The groove 13 allows workers to easily remove the mounting bracket 6, making it convenient to move and improving its usability. The cooperation between the fixing seat 14 and the fixing bolt 15 allows workers to easily and stably fix the mounting frame 1 and the filter body 2 to the mounting surface, thus improving the stability of the filter body 2. The activated carbon adsorption layer purifies the air entering the equipment, reducing the accumulation of pollutants on the heat exchanger and dehumidification components, ensuring efficient equipment operation.
