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.

[0025] This utility model provides, for example Figures 1-5 The novel air shower shown includes a main chamber 1 and an auxiliary chamber 2 symmetrically distributed. A base plate 3 is fixedly connected between the lower ends of the main chamber 1 and the auxiliary chamber 2, and a top plate 4 is fixedly connected between the upper ends of the main chamber 1 and the auxiliary chamber 2. The main chamber 1, the auxiliary chamber 2, the base plate 3, and the top plate 4 constitute the main body of the air shower. Doors 6 are rotatably mounted on the front and rear sides of the main body of the air shower via magnetic door switches 5. Inner plates 7 are provided on the sides of the main chamber 1 and the auxiliary chamber 2 that are close to each other. Several evenly arranged nozzles 8 are provided on the inner plates 7. The lower end of the inner plate 7 on the main chamber 1... A primary filter plate 11 is bolted on. A fan 12 is installed at the bottom of the main housing 1. A first air duct 13 is installed above the fan 12. A high-efficiency filter 14 is installed inside the first air duct 13. An air supply chamber is formed between the first air duct 13 and the corresponding inner plate 7. A second air duct 15 is installed at the top of the air supply chamber. A ventilation slot is installed inside the top plate 4. The auxiliary housing 2, the ventilation slot and the second air duct 15 are interconnected. An infrared sensor 9 is installed on the side of the inner plate 7. A controller 10 is installed on the side of the top of the inner plate 7 on the main housing 1.

[0026] When using this utility model, first open the front door 6 and enter the main body of the air shower. The infrared sensor 9 senses the human body and sends a signal to the controller 10 to start the fan 12. The air enters the first air duct 13, is filtered by the high-efficiency filter 14, and then enters the air supply chamber. Through the setting of the second air duct 15 and the ventilation slot, the air is simultaneously sprayed out through the nozzles 8 on both sides to give the personnel a comprehensive air bath and improve the blowing effect.

[0027] The air containing impurities after purging is filtered by the primary filter plate 11 to intercept large particles before entering the main chamber 1 for recirculation. Considering that the existing primary filter plate 11 of the air shower lacks a cleaning structure during use, requiring manual cleaning of surface impurities, which is inefficient and increases the workload of workers, a convenient component is provided on the primary filter plate 11. The convenient component includes a mounting hole, which is fixedly opened inside the primary filter plate 11. A cylinder 16 is fixedly installed inside the mounting hole, and a motor 17 is fixedly installed inside the cylinder 16. The output end of the motor 17 is fixed... Two first bevel gears 18 are provided. Upper horizontal plates 19 are fixedly provided on both sides of the primary filter plate 11. The upper horizontal plate 19 has a sliding groove inside. A reciprocating screw 20 is rotatably provided inside the sliding groove. A second bevel gear 21 is fixedly provided at one end of the reciprocating screw 20 that extends into the machine barrel 16. The second bevel gear 21 and the first bevel gear 18 mesh with each other. A movable plate 23 is threadedly connected to the outer ring of the reciprocating screw 20. The movable plate 23 is adapted to the sliding groove. A wiping plate 26 is provided on the side of the movable plate 23 through a fixing component. The wiping plate 26 and the primary filter plate 11 are in contact with each other.

[0028] Specifically, when the primary filter plate 11 needs cleaning, the motor 17 is started, which drives the two first bevel gears 18 to rotate, which in turn drives the two reciprocating screws 20 to rotate, causing the movable plates 23 on both sides of the primary filter plate 11 to move back and forth. This allows the two wiping plates 26 to wipe the two sides of the primary filter plate 11, thereby ensuring the ventilation effect of the primary filter plate 11 and avoiding the trouble of manual cleaning. This solves the problem that the primary filter plate 11 in the existing air shower lacks a cleaning structure during use, requiring manual cleaning of surface impurities, which is inefficient and increases the workload of workers.

[0029] Furthermore, both sides of the primary filter plate 11 are fixedly provided with a lower horizontal plate 22, and a limiting groove is opened inside the lower horizontal plate 22. The lower end of the movable plate 23 extends into the limiting groove. This arrangement ensures the stable displacement of the movable plate 23.

[0030] Furthermore, the fixing component includes a fixing groove 24, which is formed inside the movable plate 23. The fixing groove 24 is movably engaged with the mounting plate 25 inside the fixing groove 24. The horizontal cross-section of the mounting plate 25 is T-shaped. The wiping plate 26 is fixedly disposed on the side of the mounting plate 25. The side of the movable plate 23 is provided with two sets of symmetrically distributed locking parts. Each set of locking parts includes a rotating rod 27 and a fixing rod 28. The rotating rod 27 is rotatably disposed on the side of the movable plate 23, and the fixing rod 28 is fixedly disposed on the other side of the movable plate 23. The fixing rod 28 has a locking groove inside that is adapted to the rotating rod 27. The rotating rod 27 and the mounting plate 25 fit together.

[0031] When the wiping plate 26 needs to be cleaned or replaced, rotate the rotating rod 27 to disengage it from the locking groove. At this time, the mounting plate 25 can be removed from the inside of the fixing groove 24, and the wiping plate 26 can be cleaned or replaced. After cleaning or replacement, it can be installed in reverse. The operation is simple and quick, improving the practicality of the device.

[0032] Furthermore, nozzle 8 is designed with a round hole, which can increase the airflow rate and thus enhance the air shower effect.

[0033] Working Principle: When using this invention, first open the front door 6 and enter the main body of the air shower. The infrared sensor 9 detects the human body and sends a signal to the controller 10, activating the fan 12. Air enters the first air duct 13, is filtered by the high-efficiency filter 14, and then enters the air supply chamber. Through the second air duct 15 and the ventilation slots, the air is simultaneously sprayed out through nozzles 8 on both sides, providing a comprehensive air shower for the personnel. The air, after being blown out, is filtered by the primary filter plate 11 to intercept large particles of impurities before recirculating inside the main chamber 1. When the primary filter plate 11 needs cleaning, the motor 17 is started, carrying... The two first bevel gears 18 rotate, which in turn drives the two reciprocating screws 20 to rotate, causing the movable plates 23 on both sides of the primary filter plate 11 to move back and forth. This allows the two wiping plates 26 to wipe the two sides of the primary filter plate 11, thus ensuring the ventilation effect of the primary filter plate 11 and avoiding the trouble of manual cleaning. When the wiping plate 26 needs to be cleaned or replaced, the rotating rod 27 is rotated to disengage it from the locking groove. At this time, the mounting plate 25 can be removed from the inside of the fixing groove 24, and the wiping plate 26 can be cleaned or replaced. After cleaning or replacement, it can be installed in reverse. The operation is simple and quick.
