AI Technical Summary

Technical Problem

Existing air pressure massagers suffer from air leakage between airbags, resulting in longer airbag inflation time and lower control precision, which affects user experience and power consumption.

Method used

An air pressure adjustment device is introduced into the air pressure massager, including a pressure-holding channel, multiple three-way chambers and a one-way valve. The pressure holding and independent control of the airbag are achieved through the cooperation of the one-way valve and the solenoid valve to avoid air leakage. Energy saving and safe exhaust are achieved through the design of the air chamber solenoid valve and the exhaust channel.

Benefits of technology

It effectively solves the problem of air leakage between airbags, shortens inflation time, improves control accuracy, reduces power consumption, enhances user experience and safety, and simplifies the structure and reduces production costs.

Abstract

The application discloses a pneumatic massager and a control method thereof. The pneumatic massager further comprises a gas pressure adjusting device, a pressure maintaining channel and a three-way cavity corresponding to a plurality of air bags are arranged in the gas pressure adjusting device, each three-way cavity is communicated with the pressure maintaining channel, a first exhaust channel capable of being opened and closed is arranged on the pressure maintaining channel, a one-way valve is arranged between each three-way cavity and the pressure maintaining channel, and the one-way valve is opened from the three-way cavity to the pressure maintaining channel. The gas pressure adjusting device further comprises a plurality of air cavity electromagnetic valves arranged between each three-way cavity and the corresponding air bag. The one-way valve between the pressure maintaining channel and the air cavity can be opened by the high-pressure gas in the air bag, then the pressure difference between the inside and outside of the one-way valve is generated to close the one-way valve, so that the gas pressure in the pressure maintaining channel is kept constant, the pressure maintaining of the air bag is realized, the air leakage between the inflated air bag and the uninflated air bag in the air bag inflation process is solved, and the smooth inflation of the air bag is ensured.
