[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1, as Figure 1-Figure 3 As shown, the utility model provides a HVAC valve for HVAC equipment, comprising a valve body 1, a connecting ring 2 is fixedly installed on the inner surface wall of the valve body 1, a filter screen 3 is arranged on the inner surface wall of the connecting ring 2, a connecting plate 4 is fixedly installed on the inner surface wall of the valve body 1, a fixing ring 5 is fixedly installed on the bottom of the connecting plate 4, a micro motor 6 is arranged on the inner surface wall of the fixing ring 5, a rotating rod 7 is arranged on the output end of the micro motor 6, a cleaning brush 8 is fixedly sleeved on the outer surface wall of the rotating rod 7, an ash discharge hole 9 is provided at the bottom of the inner wall of the valve body 1, a connecting block 10 is fixedly installed on the outer surface wall of the valve body 1, a square hole 11 is provided on the top of the connecting block 10, a square groove 12 is provided on one side of the outer wall of the connecting block 10, three square grooves 2 13 are provided on the inner surface wall of the square groove 12, a sealing strip 14 is provided on the inner surface wall of the three square grooves 2 13, and a collection box 15 is movably inserted into the inner surface wall of the square groove 12.

[0024] The effect achieved by the entire embodiment 1 is that, first, when the heating valve is running, the heating air will pass through the filter 3 after entering the pipe, and the filter 3 will filter the impurities contained in the heating air, and the filtered impurities will enter the collection box 15 through the ash discharge hole 9 and the square hole 11, and the collection box 15 can be pulled out in the square groove 12, which is convenient for the user to clean the dust regularly. Secondly, some impurities will remain in the filter 3, causing the filter 3 to be blocked, affecting the use. At this time, the micro motor 6 is started to rotate the rotating rod 7, and finally the cleaning brush 8 is rotated, and the cleaning brush 8 is attached to the filter 3. When the cleaning brush 8 rotates, the brush on one side can sweep off the dust and impurities blocked on the filter 3, and finally collected by the collection box 15. By timely removing the impurities on the filter 3, the erosion and wear of the filter 3 by the impurities is reduced.

[0025] Example 2, as Figure 1 、 Figure 2 and Figure 4As shown, the outer wall of the valve body 1 is provided with two holes 16, the inner walls of the two holes 16 are movably inserted with valve stems 17, a valve plate 18 is fixedly installed between the outer walls of the two valve stems 17, a servo motor 19 is fixedly installed on the top of one of the two valve stems 17, a protective shell 20 is fixedly installed on the outer wall of the valve body 1, a group of ventilation holes 21 are provided on one side of the outer wall of the protective shell 20, and a controller 22 is fixedly installed on one side of the outer wall of the protective shell 20.

[0026] The effect achieved by the entire embodiment 2 is that when the device is in normal use, since the two valve stems 17 are fixedly connected to the valve plate 18, and one of the valve stems 17 is connected to the servo motor 19, the operation of the servo motor 19 is controlled by the controller 22, which can drive the valve plate 18 to rotate and perform opening or closing operations, thereby realizing control of the heating system. By precisely controlling the temperature and time of heating, the HVAC valve helps to reduce energy waste and achieve the goal of environmental protection and energy saving. At the same time, a protective shell 20 is provided on the outside of the servo motor 19 to protect the safety of the servo motor 19 and prevent it from colliding with the servo motor 19. At the same time, the ventilation hole 21 can ensure that the heat generated by the servo motor 19 during operation will not accumulate and affect the use of the equipment.

[0027] Among them, the micro motor 6, the servo motor 19 and the controller 22 are all existing technologies, and their components and operating principles are all public technologies, so no detailed explanation is given here.

[0028] Working principle: First, when the device is in normal use, the servo motor 19 can be operated through the controller 22, and the servo motor 19 is connected to one of the valve stems 17, one of the valve stems 17 is fixedly connected to the valve plate 18, and the bottom of the valve plate 18 is fixedly connected to the other valve stem 17. When the servo motor 19 is running, it can drive the valve stem 17 to rotate, thereby controlling the rotation of the valve plate 18, and finally controlling the opening and closing of the HVAC valve. At the same time, when the HVAC valve is in the open state, the incoming warm air will first pass through the filter 3 inside the connecting ring 2, and will be blocked by the filter 3 first to prevent these particles from entering and clogging the pipe, thereby reducing system failures and maintenance costs caused by blockages, and can also prevent large particles from damaging other equipment in the system, making the entire heating system more stable and reliable. The filter 3 is prone to being blocked when blocking impurities for a long time. At this time, the micro filter 3 is controlled by the controller 22 The motor 6 runs, causing the rotating rod 7 to rotate, and finally driving the cleaning brush 8 to rotate. The bristles on one side of the cleaning brush 8 are in contact with the surface of the filter 3. The rotation of the cleaning brush 8 can sweep away the dust and impurities on the surface of the filter 3, which helps to keep the filter 3 unobstructed, thereby ensuring the stable operation of the heating system. The swept dust and impurities will enter the interior of the connecting block 10 through the ash discharge hole 9 and the square hole 11, and will eventually be caught by the collection box 15. The collection box 15 can be pulled out, which is convenient for the user to clean the dust in the collection box 15 after a period of time. At the same time, the inner wall of the square groove 12 is provided with three square grooves 2 13, and the inner walls of the three square grooves 2 13 are all provided with sealing strips 14. The three sealing strips 14 can be in contact with the outer wall of the collection box 15, which can ensure that while dust enters the collection box 15, the circulating heating air will not flow out of the collection box 15, wasting resources.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields.
