Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by those skilled in the art without any creative work based on the embodiments of the present invention belong to the protection scope of the present invention.

The terms "comprises" and "comprising," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps is not necessarily limited to those steps or modules expressly listed, but may include other steps or modules not expressly listed or inherent to such process, method, article, or apparatus, and the division of such modules into blocks herein is merely a logical division that may be implemented in a practical application.

Example 1

As shown in figure 1, the main body part of the invention comprises a shell 6 and a handle 1, the extending direction of the shell 6 is parallel to the extending direction of the handle 1, in particular, the shell forms a 'straight' structure, a massage head 15 is not arranged at the top end of the shell 6, but arranged at the side surface of the shell 6, and the arrangement method is more powerful than a straight holding method, for example, when back knocking is required, the massage head 15 can be knocked against the back by an opposite hand.

The invention is provided with a plurality of massage heads 15, which can carry out knocking in a large range.

In particular, the invention has a unique transmission structure. The motor 3 in the housing 6 is connected, preferably by a coupling, to a crankshaft 14. The rotation center of the crankshaft 14 is parallel to the axis of the motor 3.

As shown in fig. 2, the crankshaft 14 includes two end shafts 5, and the axial center of the end shafts 5 is the rotation center. The end shafts 5 are connected to the top ends of the motor 3 and the housing 6, respectively. The middle of the two end part shafts 5 is provided with a first eccentric shaft 7 and a second eccentric shaft 8 which are eccentric to the rotation center of a crankshaft 14, the first eccentric shaft 7 and the second eccentric shaft 8 are not on the same straight line, and the first eccentric shaft 7 and the second eccentric shaft 8 are both connected with a rocker 13. Each rocker 13 comprises a first connecting end hinged to the eccentric shaft and a second connecting end hinged to the piston 12.

A plurality of parallel holes 11 which penetrate through the side wall of the shell 6 are formed in the side edge of the shell 6, the piston 12 is limited in the holes 11, and the rocker 13 pushes the piston 12 to reciprocate once when rotating once. All pistons 12 move in a direction perpendicular to the center of rotation of the crankshaft 14. The motor shaft 4 center line is vertical to the moving direction of all the pistons 12.

It is preferred. The piston 12 is provided with a socket, the massage head 15 comprises a collodion part 10 and a connecting part 9, and the connecting part 9 is inserted in the socket of the piston 12. Different massage heads 15 are convenient to replace, and the different massage heads 15 are provided with collodion parts 10 with different shapes.

The working principle is as follows: the rotation of the crankshaft 14 drives the rocker 13 to swing, the rocker 13 drives the piston 12 and the massage heads 15 to do reciprocating motion, and each massage head 15 moves back and forth with rhythmic dislocation. The staggered back and forth movement here includes when one of the massage heads 15 is in the extended longest position, the other massage head 15 is in the retracted shortest position. Thereby forming two massages in one rotation period.

The rest parts are like the existing fascia gun, circuit board components and power supplies are arranged in the shell 6, the power supplies are the batteries 2, and a charging port and a switch button are arranged outside the shell 6 and a display screen is arranged.

The battery 2 is arranged in the handle 1, the handle 1 is connected with the shell 6 by a buckle, the handle 1 can be conveniently disassembled, and the battery 2 can be disassembled in the handle 1.

Example 2

The difference from the embodiment 1 lies in the shape of the case 6 and the grip 1, specifically, as shown in fig. 3, the main body portion includes the case 6 and the grip 1, the extending direction of the grip 1 and the extending direction of the case 6 form an included angle, which is an obtuse angle, and the massage head 15 is not provided at the top end of the case 6, but is provided at the side surface of the case 6.

The principles and embodiments of the present invention have been described herein using specific examples, which are provided only to help understand the method and the core concept of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
