Description

Technical Field

[0001] This utility model relates to the technical field of air duct valves, specifically a multi-channel variable air volume distribution valve for medical cleanrooms. Background Technology

[0002] In the ventilation system of medical cleanrooms, ducts are needed to introduce fresh air into the cleanroom. However, the existing methods mostly use exhaust fans and ducts to simply inject fresh air into the cleanroom. The required fresh air volume varies depending on the size of the cleanroom. Currently, tee or multi-way ductwork is usually installed, but it is impossible to adjust the inflow and outflow of air in each duct, resulting in uneven distribution. In addition, the fresh air injected into the cleanroom cannot contain too much dust. Therefore, the existing technology needs to be improved. Utility Model Content

[0003] The purpose of this invention is to provide a multi-channel variable air volume distribution valve for medical cleanrooms to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-channel medical cleanroom variable air volume distribution valve, comprising a distribution box, a main air duct on the top of the distribution box, a secondary air duct on the side wall of the distribution box, an air volume distribution mechanism inside the main air duct, a cleaning box on the main air duct, a filter plate inside the cleaning box, and a cleaning component connected to the cleaning box for cleaning the filter plate.

[0005] Preferably, the number of auxiliary air ducts is not less than two.

[0006] Preferably, the air volume distribution mechanism includes an inner valve body disposed at the bottom of the main air duct, and several vertically penetrating ventilation holes are provided on the inner valve body. The bottom of the ventilation holes is connected to an air passage pipe, which is connected to the secondary air duct.

[0007] The ventilation opening is equipped with a spherical cavity, and a sphere is rotatably mounted in the cavity. The sphere has an outlet hole. Several regulating motors are installed on the upper surface of the distribution box. The output end of the regulating motor passes through the main air duct and the inner valve body and is fixedly connected to the side wall of the sphere. When it is necessary to adjust the air volume distribution, the regulating motor is started to drive the sphere to rotate, thereby changing the ventilation area aligned with the outlet hole and the ventilation opening, thus adjusting the air volume of each ventilation opening, thereby adjusting the air intake of the air duct. Each air duct can be adjusted individually and is not limited by the number of air ducts, making adjustment more convenient.

[0008] Preferably, the number of ventilation holes is the same as that of the secondary air ducts and they correspond one-to-one.

[0009] Preferably, the cleaning box is provided with a sliding groove, the opening of which is located on the side wall of the cleaning box. A cleaning plate is movably arranged in the sliding groove and is attached to the filter screen. A dust suction port is provided at the bottom of the cleaning plate. An installation block is provided on one side of the cleaning box. A telescopic rod is connected between the installation block and the cleaning plate. A dust suction hose is provided on the side wall of the cleaning plate and is connected to the dust suction port.

[0010] Preferably, one end of the suction hose is connected to a dust collection device.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model proposes a multi-channel variable air volume distribution valve for pharmaceutical cleanrooms. When injecting fresh air into the cleanroom, the valve features an air volume distribution mechanism. When air volume distribution needs adjustment, the regulating motor is activated to rotate the ball, thereby changing the ventilation area aligned with the flow orifice and the ventilation hole. This adjusts the airflow through each ventilation hole, thus regulating the airflow into the duct. Each duct can be adjusted individually without being limited by the number of ducts, making adjustment more convenient. Simultaneously, a filter plate is installed in the cleaning chamber to filter the injected fresh air, preventing excessive dust from entering the cleanroom. A cleaning component allows for cleaning of the filter plate, preventing excessive dust accumulation that could affect normal use. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1 to 5 This utility model provides a technical solution: a multi-channel medical cleanroom variable air volume distribution valve, including a distribution box 1. The shape of the distribution box 1 is not limited and can be square, hexagonal, circular, etc. A main air duct 2 is provided on the top of the distribution box 1, and a secondary air duct 3 is provided on the side wall of the distribution box 1. The number of secondary air ducts 3 is not less than two and can be increased according to needs. An air volume distribution mechanism is provided inside the main air duct 2.

[0021] The airflow distribution mechanism includes an inner valve body 4 located at the bottom of the main air duct 2. Several vertically penetrating ventilation holes 5 are provided on the inner valve body 4. The number of ventilation holes 5 is the same as that of the secondary air duct 3, and each ventilation hole 5 corresponds to a ventilation duct 6 connected to its bottom. The ventilation duct 6 is connected to the secondary air duct 3. A spherical cavity is provided within each ventilation hole 5, and a sphere 7 is rotatably mounted within the cavity. An overflow hole 701 is provided on the sphere 7. Several regulating motors 8 are installed on the upper surface of the distribution box 1. The output end of the regulating motor 8 passes through the main air duct 2 and the inner valve body 4 and is fixedly connected to the side wall of the sphere 7. When airflow distribution needs to be adjusted, the regulating motor 8 is started to rotate the sphere 7, thereby changing the ventilation area aligned with the overflow hole 701 and the ventilation hole 5, thus adjusting the airflow through each ventilation hole 5, and consequently adjusting the airflow into the ventilation duct 6. Each ventilation duct 6 can be adjusted individually and is not limited by the number of ventilation ducts 6, making adjustment more convenient.

[0022] A cleaning box 9 is installed on the main air duct 2. A filter plate is installed inside the cleaning box 9. A cleaning component is connected to the cleaning box 9 and is used to clean the filter plate. A sliding groove is provided inside the cleaning box 9. The opening of the sliding groove is located on the side wall of the cleaning box 9. A cleaning plate 10 is movably installed in the sliding groove and is attached to the filter screen. A dust suction port is provided at the bottom of the cleaning plate 10. An installation block 11 is provided on one side of the cleaning box 9. A telescopic rod 12 is connected between the installation block 11 and the cleaning plate 10. A dust suction hose 13 is provided on the side wall of the cleaning plate 10. The dust suction hose 13 is connected to the dust suction port, and the other end of the dust suction hose 13 is connected to a dust collection device.

[0023] After the equipment has been used for a period of time, a lot of dust will accumulate on the top of the filter screen. This dust will block the entry of fresh air, so the cleaning component needs to clean it. The vacuuming device is activated, and at the same time the telescopic rod 12 extends to push the cleaning plate 10 forward, so that it moves on the filter screen. The dust on the filter screen can be sucked away from the vacuum port, thereby ensuring that the filter screen is clean.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
