[0002] Heating, ventilation, and air conditioning (HVAC) is an air conditioner that provides heating, ventilation, and air conditioning functions. It can regulate the ambient temperature to meet people's requirements for environmental comfort and certain process requirements. To prevent impurities or harmful gases from the outside from being transported into the room through the air outlet, an air purification structure is usually installed at the HVAC air outlet.
[0003] For example, Chinese utility model patent CN212057615U discloses an air filtration and purification structure for HVAC vents, relating to the field of air conditioning technology. This structure includes an air conditioning housing with an air inlet on one side and a cavity communicating with the air inlet inside. An air filter mechanism is inserted into the cavity, and the air filter mechanism includes a mounting bracket with an integrally formed side plate at one end. This utility model achieves sliding connection between the air filter mechanism and the air conditioning housing through the use of linear sliding grooves and linear sliding strips. Simultaneously, the cooperation of locking blocks and springs enables the air filter mechanism and the air conditioning housing to be locked and fixed, thus achieving rapid disassembly and assembly of the air filter mechanism. This effectively improves the efficiency of disassembly and assembly, facilitating regular cleaning of the air purification filter and ensuring its filtration effect.

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-6 This utility model provides a technical solution: an air purification structure for a heating, ventilation, and air conditioning (HVAC) vent with adjustable function, including an HVAC body 1, a ventilation slot 2, a frame 3, a connecting plate 4, a fixing plate 5, a fixing rod 6, a limiting plate 7, a spring 8, a movable strip 9, a limiting strip 10, a purification component 11, a first filter screen 12, a second filter screen 13, an activated carbon purification plate 14, a baffle 15, a worm gear 16, a worm 17, and a limiting block 18. The ventilation slot 2 is provided inside the HVAC body 1, and the frame 3 is provided on the outer side of the ventilation slot 2, with the purification component 11 nested and fitted inside the frame 3. The air conditioner body 1 has connection limiting structures for the frame 3 on both the left and right rear sides. The connection limiting structures include a connecting plate 4, a fixing plate 5, a fixing rod 6, a limiting plate 7, a spring 8, and a movable strip 9. The connecting plate 4 is symmetrically fixed to the left and right rear sides of the HVAC body 1. The frame 3 has an adjustable shielding structure on the rear inner side. The adjustable shielding structure includes a baffle 15, a worm gear 16, a worm 17, and a limiting block 18. The baffle 15 is rotatably connected to the rear inner side of the frame 3 at equal intervals. The purification component 11 is composed of a first filter screen 12, a second filter screen 13, and an activated carbon purification plate 14.
[0028] To address the problems in existing technologies, such as the inconvenience of installing and removing the air purification structure from the HVAC unit 1, limited air purification effect, and difficulty in adjusting and controlling the airflow, this embodiment employs the following technical solution: Figure 1 , Figure 2 , Figure 3 and Figure 4First, the air purification structure can be moved next to the HVAC body 1. Then, the movable strip 9, which engages with and passes through the fixed plate 5, on the outer side of the frame 3 can be pressed inward, causing the movable strip 9 to move the limiting plate 7, which is fixedly connected to its front side, into the fixed plate 5. Next, the air purification structure can be moved and fitted to the back of the HVAC body 1, so that the frame 3 and the fixed plate 5 are respectively fitted to the HVAC body 1 and the connecting plate 4, which is fixedly connected to the back of the HVAC body 1. Then, the movable strip 9 can be released. Since the middle inner side of the fixed plate 5 is fixedly connected to the fixing rod 6, and the outer side of the fixing rod 6 is nested with the limiting plate, which engages with the fixed plate 5. 7. A spring 8 is nested on the outer side of the middle part of the fixing rod 6, and its outer end is attached to the limiting plate 7. Therefore, by loosening the movable strip 9, the limiting plate 7 can be moved outward under the elastic force of the spring 8 until the outer end of the limiting plate 7 is attached to the connecting plate 4, so that the fixing plate 5 and the connecting plate 4 are connected and limited, thereby achieving the purpose of connecting and limiting the frame 3 and the HVAC body 1. This facilitates the installation and connection of the air purification structure to the HVAC body 1. Later, the movable strip 9 can be squeezed inward to break the snap-fit between the limiting plate 7 and the connecting plate 4, so that the air purification structure can be removed from the HVAC body 1.
[0029] like Figure 2 and Figure 5 During the use of this air purification structure, air can be introduced into the air purification structure through the internal frame 3 via the HVAC body 1. Since a limiting strip 10 is fixedly connected to the upper side of the lower middle part of the frame 3, and a purification component 11 nested and attached to the front of the limiting strip 10 is provided. The purification component 11 is composed of a first filter screen 12, a second filter screen 13, and an activated carbon purification plate 14. The activated carbon purification plate 14 is attached between the first filter screen 12 and the second filter screen 13, thus facilitating the air to be filtered and purified through the first filter screen 12, the second filter screen 13, and the activated carbon purification plate 14, resulting in a good air purification effect of this air purification structure.
[0030] like Figure 1 , Figure 3 and Figure 6 The worm gear 17 is located on the right side of the rotatable frame 3, allowing it to rotate under the engagement and limiting of the limiting block 18. Since the front side of the worm gear 17 is provided with a worm wheel 16 that meshes with it, and the left side of the worm wheel 16 is fixed with a baffle 15 that is rotatably connected to the frame 3, and the baffle 15 is evenly spaced and fitted on the inner rear end of the frame 3, the rotation of the worm gear 17 facilitates the worm wheel 16 to drive the baffle 15 to rotate within the frame 3, thereby facilitating the adjustment of the baffle 15 through rotation, controlling the airflow, and improving the performance. All the components mentioned above are existing technologies and will not be described in detail here.
