[0030] As described in the background section, existing HVAC valves still have many problems. These will be explained in detail below with reference to the accompanying drawings.

[0031] The core function of HVAC valves is to precisely control the flow rate and direction of fluid media, and their sealing performance directly affects the stability and efficiency of the system. However, a large amount of dust and impurities carried in the air can easily accumulate on the valve's sealing surface, valve core, valve seat, and other critical parts when flowing through HVAC valves. These tiny particles not only increase frictional resistance but may also cause wear and scratches on the sealing surface, thereby reducing the valve's sealing effect.

[0032] Based on this, the present invention provides a heating, ventilation, and air conditioning (HVAC) valve. By adding the filter screen, dust or impurities flowing through the valve cavity can be filtered to prevent their accumulation and potential damage to the valve body or reduced sealing. When dust or impurities adhere to the surface of the filter screen, the vibration component drives the filter screen to vibrate, thereby shaking off the dust or impurities and increasing the service life of the filter screen, as well as ensuring the normal operation of the valve body.

[0033] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0036] Please refer to Figures 1 to 3 A heating, ventilation, and air conditioning (HVAC) valve includes: a valve body 100 having a valve cavity 101; an adjusting baffle 102 disposed within the valve cavity 101; an adjusting handle 103 connected to the adjusting baffle 102 and located outside the valve body 100; a filter screen 104 disposed within the valve cavity 101; and a vibration assembly 105 connected to the filter screen 104 for driving the filter screen 104 to vibrate.

[0037] By adding the filter screen 104, dust or impurities flowing through the valve cavity 101 can be filtered to prevent their accumulation and potential damage to the valve body 100 or reduced sealing. When dust or impurities adhere to the surface of the filter screen 104, the vibration component 105 drives the filter screen 104 to vibrate, thereby shaking off the dust or impurities and increasing the service life of the filter screen 104, as well as ensuring the normal operation of the valve body 100.

[0038] Please continue to refer to this. Figures 1 to 3 In this embodiment, the HVAC valve further includes a port portion 106, which is connected to both opposite sides of the valve body 100 and communicates with the valve cavity 101. The port portion 106 facilitates communication between the HVAC valve and external pipelines. The filter screen 104 is disposed at the interface between the port portion 106 and the valve body 100.

[0039] In this embodiment, by operating the rotation of the adjusting handle 103, the blocking angle of the adjusting baffle 102 is controlled, thereby realizing the adjustment of the flow rate of the HVAC valve.

[0040] Please continue to refer to this. Figure 3 and in conjunction with references Figure 4 and Figure 5In this embodiment, the vibration assembly 105 includes: a drive motor 1051; a rotating shaft 1052 connected to the drive motor 1051; a rotating cylinder 1053 mounted on the rotating shaft 1052, with a drive groove 1054 formed on the side wall of the rotating cylinder 1053; a reciprocating rod 1055 separately disposed from the rotating shaft 1052, with the filter screen 104 connected to the reciprocating rod 1055; a transition block 1056 fixedly connected to the reciprocating rod 1055; and a sliding ball 1057 fixedly connected to the transition block 1056 and assembled within the drive groove 1054.

[0041] The vibration component 105 drives the filter screen 104 to vibrate as follows: the drive motor 1051 drives the rotation of the rotating shaft 1052, which in turn drives the rotation of the rotating cylinder 1053 mounted on the rotating shaft 1052. Since the rotating cylinder 1053 has a drive groove 1054, and the sliding ball 1057 is assembled within the drive groove 1054, the rotating cylinder 1053 will not rotate laterally. During the rotation of the rotating cylinder 1053, by setting the drive groove 1054 to a specific curved shape, the sliding ball 1057 can be driven to reciprocate. The sliding ball 1057 is connected to the reciprocating rod 1055 through the transition block 1056, thereby driving the reciprocating movement of the reciprocating rod 1055. The reciprocating rod 1055 is connected to the filter screen 104, thereby driving the filter screen 104 to oscillate back and forth, thus achieving the vibration effect of the filter screen 104.

[0042] Please continue to refer to this. Figure 1 In this embodiment, the drive motor 1051 is located outside the valve body 100. By placing the drive motor 1051 outside the valve body 100, it is convenient for an external power source to be directly electrically connected to the drive motor 1051, thereby starting the operation of the drive motor 1051.

[0043] Please continue to refer to this. Figure 5 In this embodiment, the drive slide 1054 has a closed-loop structure. By setting the drive slide 1054 as a closed-loop structure, the drive motor 1051 can continuously rotate in the same direction to provide the source power for the vibration of the filter screen 104, thereby improving the vibration efficiency of the filter screen 104.

[0044] Please continue to refer to this. Figure 5In this embodiment, the rotating shaft 1052 and the reciprocating rod 1055 are arranged parallel to each other. The parallel arrangement of the rotating shaft 1052 and the reciprocating rod 1055 can minimize the space occupied by the vibration assembly 105, so that the vibration assembly 105 can be assembled more conveniently.

[0045] Please continue to refer to this. Figure 3 and Figure 5 In this embodiment, the vibration assembly 105 further includes a lug 1058, through which the rotating shaft 1052 and the reciprocating rod 1055 pass, and the lug 1058 is fixedly connected to the valve body 100. The lug 1058 provides fixed support for the various components of the vibration assembly 105 and also fixes the entire vibration assembly 105 to the valve body 100.

[0046] Specifically, the lug 1058 includes a first lug 1058a and a second lug 1058b. The rotating shaft 1052 and the reciprocating rod 1055 pass through the first lug 1058a and the second lug 1058b respectively. There is a gap between the first lug 1058a and the second lug 1058b. The rotating cylinder 1053 is disposed in the gap between the first lug 1058a and the second lug 1058b.

[0047] Please continue to refer to this. Figure 5 In this embodiment, a transition bearing 1059 is provided at the position where the rotating shaft 1052 passes through the lug 1058. The outer ring of the transition bearing 1059 is fixedly connected to the lug 1058, and the rotating shaft 1052 passes through the inner ring of the transition bearing 1059. By adding the transition bearing 1059, direct contact between the rotating shaft 1052 and the lug 1058 can be avoided, thereby reducing the frictional resistance of the rotating shaft 1052 during rotation and improving the vibration efficiency of the filter screen 104.

[0048] Please continue to refer to this. Figure 5 In this embodiment, the vibration assembly 105 further includes: a first stop 10510 and a second stop 10511, the first stop 10510 and the second stop 10511 being fixedly connected to the reciprocating rod 1055 respectively, a gap being provided between the first stop 10510 and the second stop 10511, and the filter screen 104 being located in the gap between the first stop 10510 and the second stop 10511 and being connected to the first stop 10510 and the second stop 10511 respectively.

[0049] Please continue to refer to this. Figures 3 to 5In this embodiment, the vibration assembly 105 further includes a vibration spring 10512, which passes through the filter screen 104, and its two opposite ends are fixedly connected to the first stop block 10510 and the second stop block 10511, respectively. By adding the vibration spring 10512, potential energy is accumulated, thereby increasing the vibration frequency of the filter screen 104 and improving its vibration efficiency.

[0050] Please continue to refer to this. Figure 1 In this embodiment, the HVAC valve further includes a dust storage assembly 106, which is detachably connected to the valve body 100. The dust storage assembly 106 is disposed below the filter screen 104 and is used to store debris shaken off by the filter screen 104. By adding the dust storage assembly 106, dust or impurities shaken off by the filter screen 104 can be collected. The detachable connection between the dust storage assembly 106 and the valve body 100 facilitates the handling of the collected dust or impurities by the operator.

[0051] Specifically, the dust storage assembly 106 includes: a guide pipe 1061, which is connected to the valve body 100 and communicates with the valve cavity 101; and a dust storage box 1062, which is detachably connected to the guide pipe 1061.

[0052] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
