AI Technical Summary

Technical Problem

When the existing pneumatic comfort system meets the needs of diverse users, more valve bodies are needed to control the filling and deflation of the air bag, resulting in increased costs, increased volume and increased space.

Method used

A gas switching valve is designed, including a housing, a push member, a rotary member and a reset member. Through the sliding sealing connection between the push member and the inner wall of the housing, the rotary member is driven to rotate, and the air pressure switching between multiple consumption ports is realized, and the inflation and exhaust of the air bag are controlled.

Benefits of technology

The inflation and exhaust control of multiple air bags is realized, and there is no need to set up multiple valves, saving costs and space. Since there is no solenoid valve, the system is silent and heat generation is not generated.

Abstract

The embodiment of the invention relates to the technical field of valves, and discloses a gas switching valve, a pneumatic comfort system and a massage method.The gas switching valve comprises a shell, a pushing part, a rotating part and a reset part, the shell is provided with a gas inlet and a plurality of consumption ports, the pushing part is slidably arranged in the shell, and the rotating part is arranged in the shell; the pushing part and the shell jointly form a valve chamber and an air inlet cavity communicated with the air inlet, the rotating part is provided with an inflation hole communicated with the valve chamber, the pushing part can move from a first position to a second position in the shell and drives the rotating part to rotate at the same time, and a consumption port communicated with an inflation inlet in the rotating part is switched through rotation of the rotating part. Further, the inflated air bags are switched; the pushing piece is provided with a fluid channel communicating with the valve chamber and the air inlet cavity and a valve assembly used for opening or closing the fluid channel, and the fluid channel can be opened when the pushing piece is located at the second position. By means of the mode, the cost can be saved, and the occupied space of the valve set can be saved.
