Description

Massaging chair

Technical Field

The invention relates to the technical field of furniture, in particular to a massage armchair.

Background

The chair can be divided into a massage chair and a leisure chair according to different functions.

The leisure chair is a chair which is used for people to enjoy leisure time in common; the chair is not formal like a dining chair and an office chair, has small individuality, such as a reclining chair can be formed, and a footrest can be arranged, so that comfort of a human body can be brought to the human body, and further deep relaxation of the human body is brought to the human body;

the massage chair mainly simulates manual massage, but uses mechanical rolling force and mechanical force extrusion to massage; the massage chair can perform deep massage along the spine according to the human body curve by adopting a plurality of massage techniques such as swinging, finger pressing, pinching, pushing and kneading and the like through the massage machine core; just as if someone were pounding their back and rubbing their shoulders; thereby relieving physical fatigue;

the specific structure of the massage machine core can refer to the massage machine cores related to the publication numbers of CN2922880Y, CN100382775C, CN202505713U, CN208448086U, CN109620672A, CN109846683A, CN100581523C, CN109248042A, CN109259995A, CN208448086U, TW201410230A, CN110353963A, CN110314078A, CN109172253A, CN209392344U and CN209392345U, and in general, the massage machine core realizes a plurality of massage methods such as swinging, finger pressure, pinching, pushing and kneading and the like through the massage rollers, but due to the existence of the massage rollers, the massage chair is only suitable for relieving fatigue and cannot be used as a tool for long-time rest; furthermore, the leisure chair and the massage chair become two kinds of the chair with the distinct sections on the market, and the functions of the leisure chair and the massage chair are difficult to be achieved.

The Chinese patent document with the publication number of CN109620673A discloses a massage manipulator with adjustable angle, which comprises a mounting rack and a massage head assembly, wherein the massage head assembly comprises a crank arm and a massage head, the massage head is arranged on the crank arm, the mounting rack is also provided with a kneading assembly for driving the crank arm to act with the massage head, the kneading assembly comprises a kneading shaft which is rotationally arranged on the mounting rack, the crank arm is rotationally arranged on the kneading shaft, the mounting rack is provided with an adjusting mechanism with adjustable crank arm rotation angle, the adjusting mechanism comprises a rotation seat, the rotation seat is rotationally arranged on the mounting rack, the rotation seat can drive the crank arm to rotate to realize the angle adjustment of the crank arm, and the mounting rack is provided with a driving assembly which can drive the rotation seat to rotate; through adopting above-mentioned scheme, this massage manipulator adjustable massage head's angle, be convenient for accomodate, the travelling comfort is better.

The massage mechanical arm is convenient to store, and the massage chair can be used as a leisure chair, but the cloth cover of the massage chair has good massage effect, and the cloth cover of the massage chair mainly has two methods at present: firstly, the elasticity of the cloth cover in the massage area is very big, secondly, the area of the cloth cover in the massage area is much larger than that of the massage area, so that the cloth cover in the massage area can not block the massage action of the massage rollers, but the cloth cover of the massage chair does not have the function of supporting the human body any more, and is mainly supported to be a vertical metal strip in the massage chair, so that even if the massage rollers of the massage machine core are stored back, people sit on the massage chair for rest, though the trouble of the massage rollers to the human body is avoided, people feel uncomfortable after a long time because the support is the vertical metal strip in the massage chair.
