[0025] Auxiliary component 5 includes a limiting frame 501, which is fixed to the rear end of the return air grille 3. A filter plate 502 is vertically engaged inside the limiting frame 501, and an activated carbon plate 503 is provided behind the filter plate 502. The filter plate 502 and the activated carbon plate 503 are parallel to each other, and the tops of the filter plate 502 and the activated carbon plate 503 are on the same horizontal plane as the top of the limiting frame 501. The bottoms of the filter plate 502 and the activated carbon plate 503 are... At the bottom center of the limiting frame 501, a brush holder 504 is provided on the front side of the filter screen plate 502. Several brush clusters 505 are evenly distributed on the side surface of the brush holder 504 near the filter screen plate 502. Furthermore, the brush holder 504 is movably engaged with the inside of the return air grille 3. Several brush clusters 505 on one side of the brush holder 504 are in contact with the filter screen plate 502. A snap groove 506 is provided on the side surface of the brush holder 504 away from the brush clusters 505. In this utility model, the outward movement of the return air grille 3 can effectively bring out the auxiliary component 5 as a whole, thereby reducing the disassembly process and reducing the difficulty of disassembly. After the auxiliary component 5 is removed, the filter plate 502 and activated carbon plate 503 can be pulled upward away from the limiting frame 501, making it convenient to clean or replace the filter plate 502 and activated carbon plate 503. At the same time, the dust inside the limiting frame 501 can be cleaned. During daily use, the HVAC body 1 can effectively clean the dust on the surface of the filter plate 502 by sliding the brush holder 504 to drive several brush clusters 505, reducing the possibility of filter plate 502 clogging.

[0026] It is worth noting that the convenient component 4 includes an inner groove 401, which is opened inside one side of the return air grille 3. A locking rod 402 is engaged inside the inner groove 401, and a spring 403 is sleeved on the outside of the locking rod 402. A guide plate 404 is connected to one side of the spring 403. The locking rod 402 is L-shaped, and the end of the locking rod 402 near the spring 403 is engaged inside the HVAC body 1. The two ends of the spring 403 are fixedly connected to the return air grille 3 and the guide plate 404, respectively. The guide plate 404 and the locking rod 402 are integrally formed. A protective plate 405 is fixedly sleeved on the outer side of the front end of the locking rod 402. Furthermore, when the spring 403 is in the normal state, the protective plate 405 can completely cover the front opening of the inner groove 401, and the top and bottom of the guide plate 404 are in contact with the upper and lower groove surfaces of the inner groove 401. In this invention, a set of clamping rods 402 are simultaneously moved toward the center of the return air grille 3. At this time, the side ends of the set of clamping rods 402 are detached from the inside of the HVAC body 1, and the return air grille 3 can be moved out directly without restriction, thus facilitating the quick removal of the auxiliary component 5. After the auxiliary component 5 is cleaned and reset, the return air grille 3 and the auxiliary component 5 are installed inside the HVAC body 1 based on the simultaneous movement of the set of clamping rods 402 toward the center of the return air grille 3. Then, the clamping rods 402 are released, and the side ends of the clamping rods 402 pop out and effectively engage with the inside of the HVAC body 1 due to the rebound force of the spring 403, thereby achieving quick fixation of the return air grille 3 and the auxiliary component 5. After the return air grille 3 is fixed, the protective plate 405 can effectively completely block the front opening of the inner groove 401, preventing foreign objects and dust from entering the inner groove 401.

[0027] Working principle: A set of levers 402 are simultaneously moved towards the center of the return air grille 3. At this time, the side ends of the levers 402 detach from the inside of the HVAC body 1, allowing the return air grille 3 to be moved directly without restriction. This facilitates the quick removal of the auxiliary component 5. After the auxiliary component 5 is removed, the filter plate 502 and activated carbon plate 503 can be pulled upwards away from the limiting frame 501, facilitating cleaning or replacement of the filter plate 502 and activated carbon plate 503. Simultaneously, the dust inside the limiting frame 501 can be cleaned. After the auxiliary component 5 is cleaned and reset, the return air grille 3 is moved further outwards while the levers 402 are simultaneously moving towards the center of the return air grille 3. The auxiliary component 5 is installed inside the HVAC body 1. After releasing the lever 402, the side end of the lever 402 pops out and engages with the inside of the HVAC body 1 due to the rebound force of the spring 403, thus quickly fixing the return air grille 3 and the auxiliary component 5. After the return air grille 3 is fixed, the protective plate 405 can completely cover the front opening of the inner groove 401 to prevent foreign objects and dust from entering the inner groove 401. During daily use, the HVAC body 1 can use the sliding brush holder 504 to drive several brush clusters 505 to clean the dust on the surface of the filter plate 502, reducing the possibility of the filter plate 502 becoming clogged.
