The kneading shaft includes the eccentric section and a rod section integrally formed with the eccentric section, or the kneading shaft includes a rod body and an eccentric sleeve sleeved on the rod body, and the eccentric part where the eccentric sleeve is located constitutes the Describe the eccentric section of the kneading shaft.

In this embodiment, the body is a shell, which has an inner cavity for accommodating the kneading shaft, the knocking shaft and the power mechanism, and an accommodating hole for the massage arm to protrude; or, the The body is a base.

In this embodiment, the massage arm is an integrated massaging hand part, or the massage arm includes a connecting rod and a swing rod, the connecting rod is rotatably connected to the eccentric section of the kneading shaft, and is provided with or fixedly connected There is the second matching part; the swing rod is swingably connected to the connecting rod, and an elastic member is connected with the connecting rod, and a massage wheel is mounted on the swing rod.

In this embodiment, the massage arms are divided into two groups, the two ends of the kneading shaft respectively have eccentric sections adapted to connect the two massage arms, and the two ends of the knocking shaft respectively have eccentric sections adapted to connect the two massage arms. The first mating part of the arm.

In this embodiment, the power mechanism is adaptively connected with the kneading shaft to drive the kneading shaft to rotate. Specifically, the power mechanism includes a motor, and its drive shaft can be connected to the kneading shaft through a transmission mechanism composed of a belt and a pulley or a gear transmission mechanism.

The power mechanism can also be directly connected with the massage arm to drive the massage arm to realize the kneading action. When the power mechanism is directly connected with the massage arm, the kneading shaft and the supporting shaft can also be fixedly connected to the body.

The first matching portion of the fulcrum may or may not be eccentric to its shaft.

Please refer to Fig. 8 and Fig. 9, the difference between it and the above-mentioned embodiments is that: the first matching part is a convex part 43, and the convex part 43 is connected to the shaft and can rotate relative to the shaft, specifically The convex portion 43 is connected to the shaft by a bearing 44: the inner ring of the bearing 44 is fixedly sleeved outside the shaft, and the convex portion 43 is provided with an inner hole through which it is fixedly sleeved outside the outer ring of the bearing 44. The use of the bearing 44 can greatly reduce the frictional force of relative rotation between the convex portion 43 and the shaft, thereby improving the service life of the product. Of course, if the friction factor is not taken into consideration, the protrusion 43 can also be directly movably sleeved on the outside of the shaft.

The convex portion 43 is a spherical structure with both axial ends flattened, and the second matching portion is a receiving hole 512 , specifically, the receiving hole 512 is integrally formed in the waist-shaped hole of the connecting rod 51 .

When the shaft is rotated under the control of the power mechanism to drive the massage arm to perform a knocking action, the protrusion 43 is eccentric to the shaft. Specifically, the shaft includes a first rod body 41 and a second rod body 42 that is not on the same central axis as the first rod body 41. The first rod body 41 and the second rod body 42 are integrally formed or connected, and the protrusion 43 is connected to the second rod body. The ends of the two rods 42 and their central axis coincide with the central axis of the second rod 43 , so that the protrusion 43 is eccentric to the first rod 41 . In addition, the shaft can also be a non-eccentric component, and the eccentric portion of the protrusion 43 is rotatably connected to the shaft.

When working, under the driving of the power mechanism, the shaft rotates rapidly. Since the protrusion 43 and the shaft can rotate relative to each other, the protrusion 43 does not rotate or rotates slowly, thereby greatly reducing its connection with the connecting rod. The friction between the accommodating holes 512 of the 51 is conducive to greatly improving the service life of the product.

It differs from the above-mentioned embodiments in that: the first matching portion is a convex portion, and the second matching portion is a matching surface (in addition, the first matching portion may also be a matching surface, and the second matching portion Then it is a convex part), the convex part and the mating surface are adapted and slid together, and under the action of the spring, the convex part and the mating surface are tightly fitted together, that is, the convex part will not break away from the mating surface.

When the massage arm is driven by the knock shaft to perform the knocking action, the convex part realizes eccentric movement, thereby pushing the mating surface, so that the massage arm swings outward to form a knocking action. When the convex part pushes the mating surface, the spring is in a stretched state. When the convex part rotates toward the inner side of the body and puts down the mating surface, the spring resets, thereby pulling the massage arm to reset, and keeping the mating surface closely matched with the convex part state of being together.

The above embodiments are only used to further illustrate a compact massager of the present invention, but the present invention is not limited to the embodiments, and any simple modification or equivalent change made to the above embodiments according to the technical essence of the present invention and modification, all fall within the scope of protection of the technical solution of the utility model.
