Document Type and Number:
WIPO Patent Application WO/2012/152163
Kind Code:
A1
Abstract:
Disclosed in the present invention is a washing device provided with pressure relief function comprises a box body (10), a water inlet and outlet mechanism and a pressure mechanism having a piston assembly (26), an elastic component (14) and a water injection switch (18). The box body (10) is sealed and divided into an upper chamber (18) and a lower chamber (19) by the piston assembly (26) which is provided with a pressure relief chamber (20) and a pressure relief switch for controlling the communication and closure of the upper chamber (18) and the lower chamber (19). With the design of the piston assembly (26) provided with pressure the relief chamber (20) and the pressure relief switch, water is introduced into the upper chamber (18) through the pressure relief chamber (20), not only the pressure in the lower chamber (19) is alleviated, but also the pressure balance between the upper chamber (18) and the lower chamber (19) is effectively caused to be achieved, thereby preventing the danger of the bursting of the box body (10).
