Abstract

The invention belongs to the technical field of noise elimination of massage chairs, and particularly discloses a pressure difference self-adaptive silencer for a massage chair, which can make self-adaptive adjustment for the exhaust process of the massage chair from dynamic transition to steady state within a short time. The pressure balance control and floating change of the size of each expansion cavity of the barrel are achieved through the reset force of the spring and the pressure difference of the two sides of a perforated pipe assembly. Meanwhile, an assembly type structure and an adjusting structure are adopted, and the replacement of a perforated pipe and the pre-adjustment of the volume of the cavity are achieved respectively. The silencer is flexible in structure, the position of the internal valve element is adjusted according to the working mode of the massage chair, the pressure in the whole exhaust process is adjusted in a self-adaptive mode, and the silencer has the advantages of being convenient to disassemble and assemble, low in maintenance cost, adjustable in back pressure and gas circulation area, large in transmission loss and the like.

Description

technical field [0001] The invention relates to a massage chair, in particular to a muffler for the massage chair. Background technique [0002] In recent years, people's demand for electric massage chairs has been increasing, and the working performance and comfort of massage chairs have always been the focus of people's attention. In order to improve the massage experience, more airbags need to be arranged to realize the pressing of various body parts such as the waist, back, arms, legs and buttocks. The increase in the number and size of the airbags will increase the intake and exhaust volume of the electric air pump. In the same period of time, the increase in the exhaust volume will cause the problem of increased exhaust noise, which will affect the massage experience. At present, the common massage chairs on the market have little research content on the control of exhaust noise. They often achieve fast and sufficient exhaust by simple methods such as changing the geo...
