One side of the HVAC main body is fixedly connected to an air inlet duct, and one end of the air inlet duct is fixedly installed with a filter device. A heat dissipation device is fixedly installed on the side of the HVAC main body. The filter device includes a filter housing and a dust collection plate, and the heat dissipation device includes a heat dissipation shell. This invention introduces fresh air through an air inlet duct, filters dust from the air using a dust extraction plate, disinfects the air through a disinfection pipe, eliminates bacteria in the air using a sterilization chamber and sterilization nozzles, adsorbs activated carbon from the air using an activated carbon filter plate, and finally adsorbs tiny particles inside the device body using fine microparticle adsorption balls, thereby improving the efficiency and practicality of HVAC systems.

[0003] However, it still has some drawbacks, such as: it can only filter large dust particles in the air, the filtration effect is poor, which shortens the service life of HVAC systems. After long-term use, its filter will absorb dust from the air, which will cause odors during use. It is also difficult to disinfect and sterilize the air, resulting in poor cleaning effect and failing to meet the needs of users. Summary of the Invention

[0020] like Figures 1-4 As shown, this embodiment provides a self-cleaning device for HVAC engineering, including a main body 1, a dust filter 2, a self-cleaning unit, and a quick-release mechanism. The dust filter 2 is detachably installed on the main body 1. The main body 1 and the dust filter 2 are the same as those in the prior art, and will not be described in detail here.

[0021] In this embodiment, as Figure 2 As shown, the self-cleaning unit includes a cleaning roller 12, a displacement mechanism that drives the cleaning roller 12 to reciprocate along the surface of the dust filter 2, and a dust collection box 7 located below the cleaning roller 12. The dust collection box 7 is removably mounted in the fixing groove 6 of the main body base 5 and is located directly below the movement trajectory of the cleaning roller 12. Dust is collected through the dust collection box 7, making it convenient for users or staff to clean the dust, saving time and effort.

[0022] In this embodiment, as Figure 2 As shown, the shifting mechanism includes: a fixed baffle 8 fixed to the main body 1 of the equipment, a shifting block rotatably mounted on the fixed baffle 8, a supporting horizontal plate 10 connecting the shifting block and the cleaning roller 12, and a motor driving the shifting block to rotate. The motor and its related driving method are existing technologies and will not be described in detail here. A limiting groove 11 is fixedly connected to the front outer surface of the fixed baffle 8. The supporting horizontal plate 10 is movably connected to the fixed baffle 8 through the limiting groove 11. A cleaning roller 12 is fixedly connected to one outer surface of the supporting horizontal plate 10. The cleaning roller 12 cleans dust, preventing small dust particles from being inhaled and improving user comfort. The shifting block includes two shifting blocks 9. One end of one shifting block is rotatably connected to the fixed baffle 8, and the other end is rotatably connected to the other shifting block through a fixed round rod 13 and a round rod base 14. The other end of the other shifting block is rotatably connected to the supporting horizontal plate 10.

[0023] In this embodiment, as Figure 3As shown, the quick disassembly mechanism includes a protrusion 20 on the dust filter 2 and a limiting handle 3 movably connected to the main body 1 of the equipment. The limiting handle 3 is linked to the limiting block 19 through an elastic reset component, and the limiting block 19 can engage / disengage from the protrusion 20.

[0024] Specifically, the elastic reset assembly includes: a telescopic rod 16 fixedly connected to the limiting handle 3, a telescopic spring 17 sleeved on the telescopic rod 16, and a fixing plate 18 connecting the telescopic rod 16 and the limiting block 19. The dust filter 2 is horizontally inserted into the main body 1 of the device through the filter slot 15, and its end is provided with a filter handle 21. The dust filter 2 isolates most of the dust, and the filter handle 21 allows users or staff to easily remove the dust filter 2 for cleaning. Through the cooperation of the telescopic rod 16 and the telescopic spring 17, the fixing plate 18 and the limiting block 19 can fix the dust filter 2, preventing it from falling off and affecting the normal use of the device.

[0025] In this embodiment, as Figure 4 As shown, the main body 1 of the device is also equipped with an air disinfection module, a detachable filter screen 22, and an elastic clamping assembly for fixing the filter screen 22.

[0026] The air disinfection module includes: a disinfection lamp 23 located within the airflow channel of the main body 1, and a threaded disinfection base 24 for mounting the disinfection lamp 23. The disinfection lamp 23 and the filter screen 22 disinfect and sterilize the air, ensuring user health and improving user comfort. The elastic clamping assembly includes: a fixed horizontal plate 25 and a clamping horizontal plate 27 movably connected to it, a limiting screw 26 passing through the clamping horizontal plate 27, and a limiting spring 28 sleeved on the limiting screw 26 and providing clamping force. The elastic clamping assembly is integrated into the side of the limiting baffle 4, enabling tool-free installation and removal of the filter screen 22. The front end of the main body 1 has an operation interface for controlling the start and stop of the self-cleaning unit.

[0027] The working process of the HVAC self-cleaning device used in this HVAC project is as follows: like Figures 1-4As shown, when using this device, first fix the filter screen 22 in the groove opened in the main body 1 of the device, and install the disinfection lamp 23 in the disinfection base 24. Press down on the clamping plate 27. At this time, under the action of the limiting screw 26 and the limiting spring 28, the filter screen 22 can be fixed and is not easy to fall off. Then pull the limiting handle 3 to place the dust filter screen 2 in the filter screen slot 15. After releasing, under the action of the telescopic spring 17 and the telescopic round rod 16, the limiting block 19 will engage with the protrusion 20, thereby preventing the dust filter screen 2 from falling off. At the same time, the shifting block 9 is connected by the fixing round rod 13 and the round rod base 14. With the cooperation of the shifting block 9 and the supporting plate 10, the cleaning roller 12 can be placed on the dust filter screen. The surface of the dust filter 2 moves back and forth, collecting dust in the dust collection box 7, making it convenient for users to clean the dust and improving user comfort. The support plate 10 can be fixed to the surface of the fixed baffle 8 through the set limit groove 11. The shifting block 9 is connected to the fixed round rod 13 and the round rod base 14. Driven by the motor, the shifting block 9 will rotate and drive the cleaning roller 12 to move back and forth on the surface of the dust filter 2. The dust will fall into the dust collection box 7, making it convenient for users to clean the dust at once. At the same time, by pulling the limit handle 3, the limit block 19 will disengage from the protrusion 20 under the action of the telescopic round rod 16 and the telescopic spring 17. At this time, the filter handle 21 can be pulled to take out the dust filter 2 and clean it.

[0028] Based on the above structural design, the filter screen 22 can be fixed to one side of the limiting baffle 4 under the action of the limiting screw 26, the clamping horizontal plate 27 and the limiting spring 28, so that the staff does not need to carry tools to replace the filter screen 22. Under the action of the filter screen 22 and the disinfection lamp 23, the air can be disinfected and sterilized, improving the comfort of the user.
