Description

Technical Field

[0001] The utility model relates to the technical field of air shower equipment, in particular to a channel type negative pressure air shower room. Background Art

[0002] The channel type negative pressure air shower room is a supporting equipment for clean workshops and supporting clean rooms. It is mainly used to blow away the dust attached to the surface of the human body and the objects carried by people entering the clean area, and acts as an airlock to prevent unpurified air from entering the clean area. It is an effective equipment for purifying human bodies and materials and preventing outdoor air from polluting the clean area.

[0003] During the use of the channel type negative pressure air shower room, the fan is mainly used to send air into the channel type negative pressure air shower room, and then the air is ejected at high speed through the nozzle to effectively blow away the dust and impurities attached to the surface of the human body or the objects carried. The air containing dust and impurities will be recycled into the interior of the filter equipment, filtered by the filter net, and then discharged from the channel type negative pressure air shower room through the exhaust fan, thus forming a cycle, thereby achieving the purpose of air showering;

[0004] After a long period of operation, dust will clog the filter screen in the existing channel-type negative pressure air shower room, thereby affecting the exhaust effect of the channel-type negative pressure air shower room. Although the exhaust effect of the channel-type negative pressure air shower room can be guaranteed by manually regularly clearing the filter screen, the operation is relatively cumbersome. Some channel-type negative pressure air shower rooms use multiple driving devices to drive the cleaning brush to move. Although this method can clear and clean the filter screen, it also makes the internal structure of the channel-type negative pressure air shower room more complicated and the cost is relatively high. For this reason, we propose a channel-type negative pressure air shower room. Utility Model Content
