Description

Technical Field

[0001] This utility model relates to the field of air shower technology, specifically to an air shower with a concealed magnetic lock. Background Technology

[0002] An air shower is a versatile local purification device installed between clean and non-clean rooms. When people and goods need to enter the clean area, they need to pass through the air shower. The clean air blown out can remove dust carried by people and goods, effectively blocking or reducing dust sources from entering the clean area. The front and rear doors of the air shower / cargo shower are electronically interlocked, which can also act as an airlock to prevent unpurified air from entering the clean area.

[0003] In the existing technology, magnetic locks for air showers are usually installed on the upper side of the door frame and on the inner side of the air shower top cover. However, since the door support force point is at the top, when the air shower is in an interlocked state, the door cannot be opened by force, but it is easy to be deformed by pulling. Moreover, the lock body protrudes and is installed on the inner side of the air shower top cover, which not only occupies the internal passage, but also affects the appearance. Utility Model Content

[0004] The purpose of this invention is to provide an air shower with a concealed magnetic lock to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concealed magnetic lock air shower, comprising an air shower body, door stops provided at the openings on both sides of the air shower body, and a magnetic lock body installed in the middle of the door stops, a door bow installed at the top of the door body, and the door body is rotatably installed outside the door bow with the help of a hinge, and a metal adsorption plate installed on the inner side of the door handle, and the metal adsorption plate is magnetically attracted and fixed to the magnetic lock body in the power-on state.

[0006] Furthermore, a voice control panel is installed at the top of the side wall of the air shower body, and an emergency stop button is provided on the side of the voice control panel.

[0007] Furthermore, three sets of nine nozzles are installed side by side on the middle of the side wall of the air shower body, and the nozzles are connected to the air outlet duct of the fan through a high-efficiency filter. The fan is installed on the side of the air shower body, and a primary filter is installed at the air inlet of the fan.

[0008] Furthermore, the upper row of nozzles is installed vertically upward at a 15-degree angle, the middle row of nozzles is installed horizontally, and the lower row of nozzles is installed vertically downward at a 15-degree angle.

[0009] Furthermore, a sensor is installed at the bottom of the side wall of the air shower body, and the sensor consists of an infrared transmitter and an infrared receiver arranged opposite to each other.

[0010] Furthermore, a red and green indicator light is installed on the side of the air shower body, and an emergency stop button is installed below the red and green indicator light. A fluorescent light is installed at the top inside the air shower body.

[0011] Furthermore, a grid mesh is installed at the bottom of the air shower body, and a Venturi duct is installed through the bottom of the air shower body from front to back. The venturi duct's throat and rear end are connected to the internal cavity of the air shower body through the grid mesh.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In use, this utility model has the magnetic lock body installed in the middle of the door stop, and the metal adsorption plate corresponding to it is installed on the inside of the door handle. This design makes the support force point in the middle of the door. When the air shower is in an interlocked state, the door cannot be opened by force and will not be deformed.
