Length-changeable electric massager

Abstract

The invention discloses a length-changeable electric massager. The length-changeable electric massager comprises an upper cover, a lower cover, a movable base, a massage head, a massage head transmission device and a movable base transmission mechanism, wherein the movable base moves under the traction of the movable base transmission mechanism, and the movable base transmission mechanism comprises a motor, a worm, a transmission gear, a nut and a screw. Since the movable base transmission mechanism is mainly composed of the motor, the screw and the nut, the structure is simple, the occupied space is small, and the coordination is good; the nut and the screw are meshed spirally, meshing is precise, and positioning is good; the massage head and the movable base are driven by independent power to move respectively, both movable massage and positioned massage can be realized, and a good hand-imitating massage effect can be brought to the human body.

Description

technical field [0001] The invention relates to a massager, in particular to a length-changable electric massager capable of moving massage and positioning massage. Background technique [0002] With the continuous improvement of people's living standards, the corresponding social rhythm and work pressure are also increasing. People need to relax themselves to relieve work pressure and physical and mental exhaustion. Therefore, various human health care devices have entered the public family.

AI Technical Summary

Problems solved by technology

[0004] At present, there are mainly artificial massage and mechanical massage for human back massage. Artificial massage is manual labor, which is greatly affected by human factors, and it is difficult to guarantee the quality of massage. Professionals can do it, and they can't massage anytime and anywhere; for mechanical massage, the massage method of existing massagers is too monotonous, and most of them realize the movement of the massage seat through rack transmission, so that it can achieve the effect of reciprocating massage. This masseur that realizes reciprocating massage with rack drive has the following disadvantages:

[0005] 1. The complex structure, large space occupation and poor coordination make the mobile massage lack of rhythm, which is not conducive to the massage and relaxation effect on the human body

[0006] 2. The rack and the meshing gears are exposed, and there is no corresponding device to protect them. On the one hand, impurities such as dust are easily attached to the teeth, increasing the load of the transmission and disturbing the normal speed; With the increase of use time and the long-term extrusion of human body weight, the exposed rack and the gears meshing with it are easy to deform, resulting in uncoordinated transmission speed; making the massage too mechanized, it is difficult to achieve a good relaxing effect

[0007] 3. The meshing between the rack and the gear depends on other devices for positioning to mesh with each other, which increases the cost and makes the transmission effect limited by the degree of mutual meshing, which affects the coordination of the transmission and is not conducive to imitating the effect of manual massage

[0008] 4. Only one motor is used to drive the rotation of the massage head and the movement of the moving seat at the same time. It cannot achieve positioning massage, but can only achieve the effect of massaging while moving. The massage method is too monotonous, and it cannot effectively massage the key massage areas deeply.
