Back massage device

Abstract

The invention relates to a back massage device which comprises slide groove tracks parallel to a bed surface, a transmission part, a motor and a slide bracket, wherein the motor and the slide bracket are connected to the two ends of the transmission part respectively; the slide bracket is connected with a massage column through an elastic assembly I; the massage column is connected with a massage wheel; a cavity is formed in the slide bracket; an elastic assembly II and a connecting column are fixed on the left side wall in the cavity; a magnet I is connected to the end part of the elastic assembly II, the S pole of the magnet is upward, and the N pole of the magnet is downward; a through hole is formed in the magnet I; the magnet I moves leftwards and rightwards on the connecting column through the elastic assembly II; a magnet II is arranged on the upper side wall in the cavity, and the S pole of the magnet II is downward; a magnet III is arranged at the upper end of the massage column, and the N pole of the magnet III is upward; the magnetic force of the magnet II is larger than that of the magnet III. According to the back massage device, the position of the massage wheel can be changed along with the height change of an action part, so that the back massage device has a good massage effect on parts at different heights.

Description

technical field [0001] The invention relates to a back massaging device. Background technique [0002] At present, in the field of back massage, there are two commonly used methods: one is manual massage and physical therapy massage. Manual massage is to rub and press the back to relax muscles, dilate blood vessels, and dredge meridians to achieve massage effect. , but there are physical strength maintenance problems such as short duration, low pressing force, uneven force, etc., and the effect is not accurate due to the operator's massage technology or clinical experience; equipment, but because the structure of this type of equipment is complex and expensive, it is not conducive to popularization and wide application. [0003] Therefore, appear as the disclosed device of CN101496766A as publication number, although it is simple in structure, easy to use, but this device does not have the structure that changes massage wheel position thereupon along with the change of acti...

[0002] At present, in the field of back massage, there are two commonly used methods: one is manual massage and physical therapy massage. Manual massage is to rub and press the back to relax muscles, dilate blood vessels, and dredge meridians to achieve massage effect. , but there are physical strength maintenance problems such as short duration, low pressing force, uneven force, etc., and the effect is not accurate due to the operator's massage technology or clinical experience; equipment, but due to the complex structure and high price of such equipment, it is not conducive to popularization and wide application

[0003] Therefore, appear as the disclosed device of CN101496766A as publication number, although it is simple in structure, easy to use, but this device does not have the structure that changes massage wheel position thereupon along with the change of action position height, only relies on the active force of spring to make The massage wheel has a small range of height difference. Since the overall shape of the back of the human body is curved, when the device moves to a lower position, such as the waist, it is often in a concave state, and its effect is not as high as it is at the height. The effect at a higher position is good, that is to say, the effect of the device on the waist is not as good as that on the back. Therefore, the device can only have a better effect on the waist by increasing the elastic force of the spring, but such a If the force on the back is too large, the effect will be low. Therefore, it is necessary to design a massage device that is applicable to all parts of the back.
