Abstract
The utility model relates to a self-controlled air curtain door which mainly solves the problem that mosquitoes enter along with the frequent opening and closing of the door and disturb people. A pneumatic pipe is arranged on the opening edge of a door frame. An air-jetting hole is arranged on the door frame at one side which is toward a door plate. A travel switch is arranged on the door frame above the pneumatic pipe and is connected with a control device above the pneumatic pipe. The control device is connected with an air compressor through the pneumatic pipe. When the door is opened and closed by people requiring to enter and go out of a room, the travel switch can close. A relay is closed through a control circuit, and an electromagnetic air valve is switched on. Thus, compressed air in the air compressor is ejected through the air-jetting hole on the pneumatic pipe. A large air curtain can be generated instantly, and an effect on preventing mosquitoes from entering can be achieved.
Description
Technical field
The utility model relates to door and window, particularly a kind of automatic control air curtain door that mosquito avails oneself of the opportunity to get in when preventing to open the door.
