Title:

AIR-RELEASING VALVE FOR USE IN SUCTION APPARATUS AND SUCTION ROBOT HAVING THE AIR-RELEASING VALVE

Document Type and Number:

WIPO Patent Application WO/2015/139614

Kind Code:

A1

Abstract:

An air-releasing valve for use in a suction apparatus and a suction robot having the air-releasing valve. The air-releasing valve comprises an activation unit and an air-releasing valve retaining base (3). An air-releasing hole (11) in communication with a negative pressure chamber (18) of the suction apparatus is provided on the air-releasing valve retaining base (3). The activation unit is arranged on the air-releasing valve retaining base (3) and can move relative to the air-releasing valve retaining base (3) to implement opening of the air-air-releasing hole (11). A switch (4) is arranged on the air-releasing valve retaining base (3). When the air-releasing hole (11) is opened by the activation unit, the activation unit triggers the switch (4) to shut off a vacuuming apparatus (14) of the suction apparatus. The air-releasing valve is capable of rapidly releasing air for the suction apparatus and of shutting off the vacuuming apparatus (14) in a timely manner.
