DETAILED DESCRIPTION

The following is a further detailed description of the present invention or the technical solution of the present invention through specific embodiments and in conjunction with the accompanying drawings of the specification;

In the description of the present invention, it should be understood that the terms "front", "rear", "up", "down", "left", "right", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

In the description of the present utility model, it should be noted that, unless otherwise specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

Please refer to Figures 1 to 4. This embodiment provides a massager, which includes a housing 1 and two groups of massage mechanisms 2 and 3. The housing defines an installation space. Since the two groups of massage mechanisms are the same, only one of the groups of massage mechanisms is described in detail below:

Each group of massage mechanisms includes a double-headed motor 29, a first eccentric wheel 27 and a second eccentric wheel 28, a first massage head 21 and a second massage head 22. The double-headed motor 29 is installed in the installation space. The double-headed motor 29 here refers to a single motor shaft with joints at both ends. The first eccentric wheel 27 and the second eccentric wheel 28 are installed in the installation space. The first eccentric wheel 27 and the second eccentric wheel 28 are connected to the left and right ends of the double-headed motor 29 respectively. The first massage head 21 and the second massage head 22 are arranged on the outside of the shell. The first connecting member 25 and the second connecting member 26 are movably arranged on the shell. The first massage head 21 is connected to the first eccentric wheel 27 through the first connecting member 25, and the second massage head 22 is connected to the second eccentric wheel 28 through the second connecting member 26. In this way, the first eccentric wheel 27 and the second eccentric wheel 28 are driven to rotate simultaneously by the double-headed motor 29. The rotation of the first eccentric wheel 27 and the second eccentric wheel 28 drives the first connecting member 25 and the second connecting member 26 to perform reciprocating eccentric rotation around the eccentric axis of the eccentric wheel. Furthermore, due to the movable arrangement of the first connecting member 25 and the second connecting member 26 on the shell, the first massage head 21 and the second massage head 22 are driven to perform reciprocating motion.

It is understandable that the reciprocating motion trajectory of the first massage head 21 and the second massage head 22 depends on the guiding cooperation between the first connecting member 25 and the second connecting member 26 and the housing 1. In some embodiments, the housing 1 is formed with a first limiting groove and a second limiting groove extending in the vertical direction, and the first connecting member and the second limiting member are telescopically arranged in the first limiting groove and the second limiting groove. That is, the first connecting member 25 and the second connecting member 26 drive the first massage head 21 and the second massage head 22 to reciprocate along the up and down direction due to the limiting effect of the first limiting groove and the second limiting groove. Specifically, the massage mechanism also includes a first telescopic sleeve 23 and a second telescopic sleeve 24 arranged on the shell, the first telescopic sleeve and the second telescopic sleeve define a first limiting groove and a second limiting groove, the first massage head 21 and the second massage head 22 extend outward from the first telescopic sleeve 23 and the second telescopic sleeve 24 respectively, the first telescopic sleeve 23 and the second telescopic sleeve 24 limit the first connecting member 25 and the second connecting member 26, so that the end connected to the first massage head and the second massage head only reciprocates up and down.

It is understandable that the massage mechanism may have only one group or may include more than two groups. The more groups of massage mechanisms, the more massage heads the massager has. In some embodiments of the present utility model, the rotation of each double-headed motor is controlled by a control circuit, and the two motors can be controlled to move simultaneously, or one of the motors can be controlled to rotate separately. In this embodiment, the two groups of massage mechanisms are arranged in parallel, wherein the two groups of double-headed motors are arranged in parallel front to back, the first massage head and the second massage head of each group of massage mechanisms are arranged symmetrically left to right, and the two groups of first massage heads and second massage heads are arranged in parallel along the front-to-back direction. Exemplarily, a battery pack and a control circuit are installed between the first massage mechanism and the second massage mechanism, the battery pack provides power for the entire massager, and the control circuit controls the operation of the dual-axis motor and the massage head.

In some embodiments of the present invention, the double-headed motor 29 has a single motor shaft, and the eccentric axis of the first eccentric wheel 27 is offset compared to the eccentric axis of the second eccentric wheel 28, that is, the eccentric axis of the first eccentric wheel 27 and the eccentric axis of the second eccentric wheel 28 do not coincide with each other, but are staggered from each other. In this way, when the double-headed motor 29 is driven, the first eccentric wheel 27 and the second eccentric wheel 28 rotate synchronously around the motor shaft axis of the double-headed motor 29. At this time, the eccentric axes of the first eccentric wheel 27 and the second eccentric wheel 28 do not coincide, and the telescopic vibrations of the first massage head 21 and the second massage head 22 do not occur synchronously, and the first massage head 21 and the second massage head 22 distributed on the left and right produce a vibration effect one after the other. Preferably, the eccentric axis of the first eccentric wheel is offset by 180° compared to the eccentric axis of the second eccentric wheel. In this way, the first massage head and the second massage head bring continuous and counteracting massage effects, so that the massager can always produce a massage effect on the body, avoiding the problem of instantaneous cessation of the massage action when the two massage heads are coaxially connected.

In some embodiments, the first massage head 21 is connected to the first connecting member 25 via the first bearing 20, and the second massage head 22 is connected to the second connecting member 26 via the second bearing 30. In this way, the friction between the massage heads 21, 22 and the connecting members 25, 26 is reduced by the first bearing 20 and the second bearing 30, which significantly reduces the noise of the massager during massage, and the vibration action of the massage head is smoother and more stable.

In this embodiment, the first connecting member 25 and the second connecting member 26 include connecting rods for transmission, and the eccentric wheel is connected to the massage head via the connecting rods.

Specifically, the first eccentric wheel 27 has the same structure as the second eccentric wheel 28, and the first connecting member 25 and the second connecting member 26 have the same structure. The structure of the eccentric wheel is described below by taking the second eccentric wheel and the second connecting member as examples. The second eccentric wheel 28 includes a wheel body 281 and an eccentric shaft 282 eccentrically arranged with the wheel body 281. The wheel bodies of the first eccentric wheel 27 and the second eccentric wheel 28 are respectively fixedly connected to the two end joints of the double-headed motor 29. The first connecting member 25 and the second connecting member 26 include a connecting rod and a bearing seat 261 connected to the end of the connecting rod.

The first bearing 20 and the second bearing 30 are deep groove ball bearings, the eccentric shaft 282 is connected to the inner ring of the deep groove ball bearing 30 , and the bearing seat 261 is connected to the outer ring of the deep groove ball bearing 30 .

The first massage head 21 and the second massage head 22 are plugged into the top ends of the connecting rods of the first connecting member 25 and the second connecting member 26 . The top ends of the connecting rods are telescopically limited by the first telescopic sleeve 23 and the second telescopic sleeve 24 .

Exemplarily, the connecting rod includes a vertically extending straight section 263 and a bent section 262 that extends in a bent manner. The straight section 263 is arranged toward the inside compared to the bent section 262. The bent section 262 is connected to the bearing seat 261. The ends of the straight section 263 are suitable for plugging with the first massage head 21 and the second massage head 22. The "inside" here means that compared with the massager itself, the side facing the massager is the inside, and the side away from the massager is the outside. The straight section here is closer to the massager body. In this way, the first massage head and the second massage head plugged with the straight section are closer, that is, they are closer to each other, which is more suitable for the design of a small massager, avoiding the technical problem of the massager being too large in size due to the two massage heads being too far apart.

The shell 1 provided in this embodiment includes an upper shell 100 and a lower shell 101. The first telescopic sleeve and the second telescopic sleeve of the two groups of massage mechanisms are arranged through the lower shell 101, and the first massage head and the second massage head are limitedly telescopic in the first telescopic sleeve and the second telescopic sleeve; the double-headed motor 29, the first eccentric wheel 27 and the second eccentric wheel 28 are all installed inside the shell. The massager is small in size. Hand-held bracelets 11 and 12 are formed on both sides of the shell 1. When used, the massage head can be placed on the place where massage is needed by holding the bracelet with both hands, or the place to be massaged can be placed against the massage head.

In some other embodiments, the massage head also has an infrared heating function.

The massager provided by the utility model comprises a plurality of massage mechanisms, each of which comprises a double-headed motor,

The first eccentric wheel and the second eccentric wheel and the first massage head and the second massage head, the double-headed motor drives the two eccentric wheels to rotate, and then drives the first massage head and the second massage head connected to the two eccentric wheels to rotate. The massager provided by the utility model can provide multiple massage heads.

The utility model can realize an up-and-down massage effect by specifically designing the eccentric axes of the two eccentric wheels of the same massage mechanism.
