Title:
AIR PRESSURE ADJUSTMENT DEVICE, AIR PRESSURE MASSAGE INSTRUMENT, AND CONTROL METHOD FOR AIR PRESSURE MASSAGE INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2024/045906
Kind Code:
A1
Abstract:
An air pressure adjustment device, an air pressure massage instrument, and a control method for the air pressure massage instrument. The air pressure adjustment device comprises a base body (100); a gas inlet channel and a plurality of gas cavities are formed in the base body (100); each gas cavity is communicated with a gas inlet cavity capable of being opened and closed; the gas inlet cavities are communicated with air bag connecting pipes (400); the positions of the gas cavities not communicated with the gas inlet cavities are communicated with the gas inlet channel; a one-way valve (321, 322, 323, 324, 325) is arranged at the joint of each gas cavity and the gas inlet channel; each one-way valve (321, 322, 323, 324, 325) is opened in the direction from the gas cavity to the gas inlet channel; and the gas inlet channel is further communicated with a gas inlet channel gas inlet capable of being opened and closed and a first gas discharging channel (220) capable of being opened and closed. Air bags connected to the air bag connecting pipes (400) on the air pressure adjustment device are subjected to pressure maintaining by means of the air pressure adjustment device, and gas can be inflated into the gas inlet channel of the air pressure adjustment device to enable the inner side and the outer side of each one-way valve (321, 322, 323, 324, 325) to have a pressure difference, such that the gas inlet cavities communicated with the air bag connecting pipes (400) are closed, and the gas in the air bags cannot flow and thus does not flow back, thereby implementing the pressure maintaining of the air bags.
