Document Type and Number:
WIPO Patent Application WO/2022/062972
Kind Code:
A1
Abstract:
A pump-valve integrated pneumatic control module, comprising: a pump-valve body of which the end portion is provided with a gas distribution layer (16), and a gas guide module (1) mated with the gas distribution layer (16), and an electric control module used for controlling the pump-valve body and the gas guide module (1). The gas guide module (1) is provided on the end portion of the pump-valve body, and a bidirectional elastic sealing body (5) is provided in a gas distribution chamber of the gas guide module; a memory alloy wire (10) is provided between a first electrode (11) and a second control unit (9), and the memory alloy wire (10) is electrically connected to the two; the memory alloy wire (10) is connected to the end portion of the bidirectional elastic sealing body (5) passing through a deflation port (4), so as to control gas intake or deflation of a pneumatic cavity; a gas inlet (2) receives a gas from a gas distribution layer outlet (15); the memory alloy wire (10) is powered on to operate, and pulls the bidirectional elastic sealing body (5) to open the gas inlet (2); the gas enters the gas distribution chamber through the gas inlet (2) and flows into the pneumatic cavity from a gas outlet (3). Also disclosed are a massage system and an automobile seat. The pneumatic control module inflates the pneumatic cavity by using the pump-valve body to achieve a pneumatic massage function.
