The structure of the housing 10 has various forms, in some embodiments, the housing 10 includes an upper shell 11 and a lower shell 12, the upper shell 11 and the lower shell 12 form a first cavity 181, the driving component 30 is located in the first cavity 181, is disposed at one end of the first cavity 181 far away from the reciprocating part 20, and is located at the rear end of the housing 10, preferably, the housing 10 has heat dissipation holes 111 at positions corresponding to the driving component 30, and the heat dissipation holes 111 are in a strip shape and are circumferentially and uniformly distributed on the rear end surface of the upper shell 11 or the lower shell 12.

In other embodiments, the housing 10 includes an upper shell 11, a lower shell 12, and a rear end cap, the upper shell 11, the lower shell 12, and the rear end cap collectively forming the first cavity 181, and the drive assembly 30 is at least partially located within the rear end cap. Preferably, the casing 10 has heat dissipation holes 111 at positions corresponding to the driving assembly 30, and the heat dissipation holes 111 are strip-shaped and circumferentially and uniformly distributed on the surface of the rear end cover.

The heat dissipation holes 111 are used to enhance the heat dissipation performance and prevent the heat accumulation from damaging the whole body, and the heat dissipation holes 111 may correspond to the positions of the driving assembly 30 and the charging assembly.

The drive assembly 30 includes a drive motor, an output shaft 31 of which is connected to the transmission assembly 40. In some embodiments, the drive motor is at least partially disposed within the rear end cap. In order to convert the rotational motion of the driving assembly 30 into the reciprocating motion of the reciprocating part 20, the driving assembly 40 is a multi-link structure, and the driving assembly 40 includes an eccentric member 41, a pull link 42, a swing link 43, a connecting bearing 46, a swing link 44, and a link 45. The lifting link 42 converts the rotation of the eccentric 41 into a linear motion, such as a horizontal motion or a vertical motion; the swinging link 43 converts the linear motion into the swinging motion, for example, converts the vertical motion into the back-and-forth swinging motion, or converts the horizontal motion into the up-and-down swinging motion, and the back connection bearing 46 connects the swinging link 43 and the swinging rod 44, and converts the swinging motion into the linear reciprocating motion to drive the massaging head 23 to reciprocate.

By way of example only, in the manner shown in the drawings, the output shaft 31 of the drive motor is parallel or collinear with the transverse axis 18, and the transmission assembly 40 is substantially collinear with the drive motor; specifically, the eccentric member 41 is disposed on the output shaft 31, rotates along with the output shaft 31, and is responsible for generating eccentric power output, and the eccentric member 41 may be an eccentric wheel; one end of the lifting connecting rod 42 is rotatably connected with the eccentric part 41, and the rotating motion of the eccentric part 41 is converted into vertical motion; one end of the swing link 43 is rotatably connected to the other end of the lifting link 42, and the other end is connected to the swing link 44 through a link bearing 46, so that the vertical movement of the lifting link 42 is converted into a back-and-forth swing movement. Preferably, a step with a certain thickness is further required at the connection between the eccentric member 41 and the pulling link 42 to prevent the swinging link 43 from rubbing against the eccentric member 41 during swinging, thereby generating noise and even being damaged.

Since the swing link 44 swings back and forth, the distance between the swing link 44 and the lifting link 42 changes back and forth along with the swing, and the lifting link 42 moves vertically up and down, and the position in the transverse direction remains unchanged, the swing link 43 functions as: when the lifting connecting rod 42 moves up and down and the swing rod 44 swings back and forth, the swing rod is rotated by a proper angle, so that the front and back displacement generated by the up and down swing of the swing rod 44 is eliminated, the stable transmission of power is ensured, and the transmission assembly 40 is prevented from being locked; meanwhile, the swing rod 44 is fixedly connected with the connecting bearing 46, when the swing rod 44 needs to drive the connecting rod 45 to move back and forth, one end, close to the motor, of the swing rod 44 needs to move up and down, the connecting bearing 46 can generate an angle change relative to the outer surface of the eccentric part 41 at the moment, the back and forth swing of the swing connecting piece 43 can just offset the influence of the angle change at the moment, and the damage to the transmission assembly 40 caused by the angle change of the connecting bearing 46 is prevented. Specifically, the connecting bearing 46 is used for rotating the eccentric member 41 around the transverse axis 18 when the eccentric member 41 rotates, the connecting end of the eccentric member 41 and the pulling connecting rod 42 is offset to the left or right relative to a vertical axis perpendicular to the transverse axis 18 and passing through the center of the output shaft 31 of the driving motor, so as to generate a transverse variation and a longitudinal variation, the pulling connecting rod 42 is inclined to the upper oblique direction and forms an angle with the vertical axis, the longitudinal variation drives the swing rod 44 to swing, and the inner ring of the connecting bearing 46 connected to the other end of the pulling connecting rod 42 rotates a certain angle relative to the outer ring, so as to offset the transverse variation of the pulling connecting rod 42, and prevent the swing rod 44 from rotating.

The swing rod 44 is arranged on the mounting rack 17 in a manner of swinging back and forth, one end of the connecting rod 45 is connected with the swing rod 44, the other end of the connecting rod 45 is connected with the reciprocating part 20, the connecting rod 45 moves back and forth under the action of the other end of the swing rod 44, meanwhile, the through hole at the front end of the shell 10 limits the reciprocating part 20, the back and forth swinging is converted into back and forth reciprocating motion, and the reciprocating part 20 drives the massage head 23 on the reciprocating part to do reciprocating motion to strike and massage muscles and fascia. Above-mentioned structure can be very big the reduction to the waste of the power of drive assembly 30 output, has improved the energy utilization of manadesma rifle, simultaneously, because drive assembly 30 and transmission assembly 40 set up in first cavity 181, kept away from the handle 13 that the user gripped, lightened user's hand burden, user's multiplicable single use time brings better result of use for the user.
