Background

With the development of society, the working pressure of people is continuously increased, the bodies of people are carried in overload every day, and the sub-health state of the bodies can be caused by high-strength working strength. If the massage is not performed, the whole health of the human body is affected by the problems of long-term muscle pain strain, qi and blood obstruction, meridian obstruction and the like. Thus, massage chairs have become very popular conditioning leisure equipment in homes, parts of offices and even malls. Many massage chairs are currently available on the market, but most of them are directly mounted on the back. In order to ensure the massage effect, the rotary massage heads of the massager are often arranged to be more prominent, which also causes the user to feel a sense of being in touch with the backrest when not in massage, and reduces the user experience.

On the basis, the applicant previously submits a part of application number as follows: 2022219530315 the utility model provides a patent application with the name of an intelligent induction type lifting massage chair and a massage chair back thereof, which provides that a massage module rotates along a hinged end and enables a working end of the massage module to swing back and forth relative to the chair back. So that the massage head can automatically extend out for massage when the massage function is started; when the massage function is closed, the massage head can be automatically retracted, and more comfortable seat experience is provided for the user.
