Description

Technical Field

[0001] This utility model relates to the field of air volume valve technology, specifically an air volume valve that can prevent dust and disinfect. Background Technology

[0002] In industrial ventilation and building air conditioning systems, air volume valves are key components for controlling airflow, and their performance directly affects the system's operating efficiency and stability. Traditional air volume valves typically employ vane or butterfly valve structures, controlling airflow by adjusting the angle of the vanes or valve discs.

[0003] Because existing air volume valves generally lack adequate dust prevention measures, a large amount of dust can easily enter the room directly through the gaps between the valve body and the blades or valve discs, seriously affecting the indoor environmental hygiene. At the same time, although some air volume valves equipped with filters can intercept some dust, the filters need to be replaced frequently, and the filters are difficult to disassemble. Maintenance and cleaning require complex disassembly of the air volume valve, which is not only time-consuming and laborious, but also easily damages the valve body's sealing performance. Utility Model Content

[0004] The purpose of this utility model is to provide a dustproof and disinfecting airflow valve. By setting an electrostatic adsorption plate inside the valve body, the electrostatic adsorption plate generates static electricity to adsorb dust after being energized, and the dust is blocked by the filter plate. In addition, the air is disinfected by ultraviolet lamp tube, thus achieving the function of dustproofing and disinfection.

[0005] To address the problems of existing technologies, this utility model provides a dustproof and disinfecting airflow valve, comprising: a valve body that can be installed on a wall; an electrostatic adsorption plate that can be detachably installed at the air inlet inside the valve body and can adsorb dust in the air; a filter plate that can be detachably installed inside the valve body to block dust; and detachable ultraviolet lamps that disinfect the air are vertically installed on the two side walls and the center of the valve body. When air enters the valve body, the electrostatic adsorption plate can adsorb dust in the air.

[0006] Preferably, the inner wall of the air inlet end of the valve body is provided with a groove along its length that can cooperate with the ultraviolet lamp tube, and the ultraviolet lamp tube can move back and forth in the groove.

[0007] Preferably, the electrostatic adsorption plate has a plurality of fins extending to both sides along its length.

[0008] Preferably, the filter plate has a limiting groove on the side near the electrostatic adsorption plate that cooperates with the electrostatic adsorption plate, and the electrostatic adsorption plate and the limiting groove are slidably engaged.

[0009] Preferably, the valve body has a stop block for limiting the position of the filter plate. The stop block has a rotatable limiting element. The filter plate has a through groove around its perimeter that cooperates with the limiting element. When the limiting element is parallel to the through groove, the limiting element can pass through the through groove. When the limiting element is perpendicular to the through groove, the filter plate can be fixed in the valve body.

[0010] Preferably, the surface of the filter plate is further provided with a silver ion coating.

[0011] Preferably, the valve body has a plurality of valve plates rotatably arranged inside, which can control the opening or closing of the valve body. The valve plates are arranged in front of the filter plate, and the valve body is also provided with a drive mechanism for driving the valve plates to rotate synchronously.

[0012] Preferably, the drive mechanism further includes a transmission rod fixedly mounted on the valve plate, and the drive mechanism further includes a connecting rod that can be rotatably connected to the transmission rod and is used to drive the valve plate to rotate synchronously. The drive mechanism also includes a rotary drive component fixed at the center position on the side of the valve body, and the output end of the rotary drive component is connected to a rotary shaft on one of the valve plates.

[0013] The advantages of this utility model compared to the prior art are:

[0014] This application proposes an airflow valve that achieves a comprehensive effect of dust filtration, electrostatic adsorption, and air disinfection. Specifically, a filter plate is installed in the internal airflow channel of the valve body. This filter plate intercepts airborne particles through physical barrier, effectively reducing the amount of dust passing through. Simultaneously, an electrostatic adsorption plate is installed within the valve body. When powered on, this plate generates an electrostatic field, capturing charged particles in the air using electrostatic adsorption, significantly reducing the dust load on the filter plate and extending its service life. Furthermore, an ultraviolet lamp is installed inside the valve body. This lamp emits ultraviolet light of a specific wavelength to radiate and disinfect the air flowing through the valve body, effectively killing bacteria and viruses in the air. In addition, the filter plate surface is coated with an antibacterial coating, which inhibits the adhesion and reproduction of microorganisms on the filter plate surface, further enhancing the purification effect. The surface of the electrostatic adsorption plate has multiple fin structures. These fins significantly improve electrostatic adsorption efficiency by increasing the adsorption area. For ease of maintenance, both the filter plate and the electrostatic adsorption plate are designed to be detachable. When the limiting component rotates to be parallel to the through groove, the filter plate can be pulled out along the through groove; similarly, the electrostatic adsorption plate can also be pulled out, which facilitates regular cleaning of accumulated dust and ensures long-term stable operation of the equipment.

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figures 1-6 As shown, this utility model provides a dustproof and disinfecting airflow valve, including: a valve body 1, which can be installed on a wall; an electrostatic adsorption plate 2, which can be detachably installed inside the valve body 1 at the air inlet and can adsorb dust in the air; a filter plate 6 that can be detachably installed inside the valve body 1 to block dust; and detachable ultraviolet lamps 8 that disinfect the air are vertically installed on the two side walls and the center position inside the valve body 1. When air enters the valve body 1, the electrostatic adsorption plate 2 can adsorb dust in the air.

[0024] When air enters valve body 1, it first passes through electrostatic adsorption plate 2 located at the air inlet. Electrostatic adsorption plate 2 uses electrostatic adsorption to attract dust particles from the air onto its surface, achieving preliminary filtration and reducing the dust content. The air, after preliminary filtration by electrostatic adsorption plate 2, continues to flow within valve body 1 and then encounters filter plate 6. Filter plate 6 further blocks dust. During the airflow through valve body 1, ultraviolet lamps 8, vertically positioned on both sides and at the center of valve body 1, continuously operate, emitting ultraviolet light. This ultraviolet light irradiates the passing air, destroying the structure of bacteria, viruses, and other microorganisms in the air, killing them, and achieving air disinfection. Through the preliminary dust prevention of electrostatic adsorption plate 2, the further dust prevention of filter plate 6, and the disinfection effect of ultraviolet lamps 8, the entire dustproof and disinfecting airflow valve effectively purifies and disinfects the air entering valve body 1, providing cleaner and more hygienic air for the ventilation system.

[0025] The inner wall of the air inlet end of the valve body 1 is provided with a groove 11 along its length that can cooperate with the ultraviolet lamp 8, allowing the ultraviolet lamp 8 to move back and forth within the groove 11. The design of the groove 11 facilitates the installation and removal of the ultraviolet lamp 8. During installation, the ultraviolet lamp 8 can be easily inserted along the groove 11; during removal, the ultraviolet lamp 8 can also be easily removed from the groove 11.

[0026] The electrostatic adsorption plate 2 has several fins extending to both sides along its length, increasing the contact area between the electrostatic adsorption plate 2 and the air. A larger contact area means it can adsorb more dust particles, further improving dustproof efficiency.

[0027] A limiting groove 3 is provided on the side of the filter plate 6 near the electrostatic adsorption plate 2, which cooperates with the electrostatic adsorption plate 2. The electrostatic adsorption plate 2 and the limiting groove 3 are in sliding fit. When a lot of dust is adsorbed on the surface of the electrostatic adsorption plate 2, affecting the adsorption effect, it can be disassembled for cleaning or replacement to ensure continuous and effective dust prevention function.

[0028] A stop 7 is provided on the inner wall of the valve body 1 to limit the filter plate 6. A limiting element 71 is rotatably provided on the stop 7. A through groove 61 that cooperates with the limiting element 71 is opened around the filter plate 6. When the limiting element 71 is parallel to the through groove 61, the limiting element 71 can pass through the through groove 61. When the limiting element 71 is perpendicular to the through groove 61, the filter plate 6 can be fixed in the valve body 1. The surface of the filter plate 6 is also provided with a silver ion coating.

[0029] When the limiting member 71 is parallel to the through groove 61, the limiting member 71 can pass through the through groove 61, facilitating the installation and removal of the filter plate 6; when the limiting member 71 is perpendicular to the through groove 61, the filter plate 6 can be fixed in the valve body 1, ensuring its stability during operation. Silver ions can destroy the cell walls and cell membranes of bacteria, viruses, and other microorganisms, interfering with their normal physiological metabolic processes, thereby achieving the purpose of inhibiting and killing microorganisms. This prevents pathogens from multiplying on the filter plate 6.

[0030] The valve body 1 has several valve plates 4 rotatably mounted inside, which can control the opening and closing of the valve body 1. The valve plates 4 are located in front of the filter plate 6. The valve body 1 is also equipped with a drive mechanism 5 for driving the valve plates 4 to rotate synchronously. The drive mechanism 5 also includes a transmission rod 52 fixedly mounted on the valve plate 4, and a connecting rod 53 rotatably connected to the transmission rod 52 for driving the valve plates 4 to rotate synchronously. The drive mechanism 5 also includes a rotary drive component 51 fixed at the center position on the side of the valve body 1. The output end of the rotary drive component 51 is connected to a rotating shaft on one of the valve plates 4.

[0031] When valve body 1 needs to be opened, the rotary drive component 51 of the drive mechanism 5 is activated. The output end of the rotary drive component 51 drives the rotary shaft on a valve plate 4 connected to it to rotate, and the transmission rod 52 on the rotary shaft rotates accordingly. Since the connecting rod 53 is rotatably connected to the transmission rod 52, the connecting rod 53 will transmit power to the transmission rods 52 on other valve plates 4, so that all valve plates 4 rotate synchronously, gradually opening the air passage, opening valve body 1, and allowing air to smoothly enter valve body 1.

[0032] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
