As shown in fig. 1 to 8, the present embodiment illustrates a compact mini fascia gun, which mainly includes a housing, a fixing sleeve 300 and a massage head 500 provided on the housing, a motor 700 provided in the housing, a crank link mechanism 600, a battery assembly 800, and an elastic sleeve 400 provided outside the housing.

The whole shell is in a round table shape, and a containing cavity with an opening is formed in the shell. The shell is big in one end and small in one end, and the opening is located at the smaller end. In use, a user may hold the larger end. In this embodiment, the housing includes a left half shell 100 and a right half shell 200, where the left half shell 100 and the right half shell 200 are combined to form the accommodating cavity with an opening.

Specifically, hollow connection posts 110 are provided in the left half case 100 and the right half case 200, respectively. When the left half shell 100 is combined with the right half shell 200, the connecting posts 110 between the two are butted. A screw for fixing is provided in the connection post 110.

The massage head 500 is movably disposed in the opening. One end of the massage head 500 extends out of the opening, and the other end of the massage head 500 is positioned in the opening and connected with the crank-link mechanism 600. In this embodiment, the fixing sleeve 300 is annular and is fixed at the opening to fix the left half shell 100 and the right half shell 200 together, and one end of the massage head 500 extends out from a hole in the middle of the fixing sleeve 300, and the hole in the middle of the fixing sleeve 300 has a certain depth, so that the massage head 500 is slidably connected with the hole wall, and the massage head 500 can stably reciprocate therein.

In this embodiment, the motor 700 is disposed in the accommodating chamber. Specifically, the motor 700 is fixed within the left half-shell 100. More specifically, a fixing plate 130 for fixing the motor 700 and at least three columns 120 for fixing the fixing plate 130 are provided in the left half shell 100, the fixing plate 130 is fixed on a mounting surface formed by the columns 120, one end of the motor 700 is fixed on the fixing plate 130, the motor 700 comprises a motor 700 shell and a motor shaft 710, the motor 700 shell and the fixing plate 130 are fastened by bolts, and the motor shaft 710 is arranged on the fixing plate 130 in a penetrating manner.

In this embodiment, four columns 120 are disposed in the left half shell 100, and four mounting holes are formed at four corners of the rectangular fixing plate 130 to mount the columns 120. Since the motor 700 drives the fixing plate 130 to vibrate together when rotating, in this embodiment, a rubber sleeve capable of elastically buffering is disposed in the mounting hole, and the ports on both sides of the rubber sleeve are provided with edges to attach to both sides of the fixing plate 130. The rubber sleeve and the upright 120 are adhered and fixed by glue.

In this embodiment, the crank mechanism 600 is configured to receive the torque of the motor 700 and drive the massage head 500 to reciprocate in the fixed housing 300.

Specifically, the crank-link mechanism 600 includes a crank 610 having one end connected to the motor 700, and a link 620 connected to the other end of the crank 610. The distal end of the link 620 is connected to the massage head 500. One end of the crank 610 is further provided with an integrally formed balancing weight 611, and the balancing weight 611 is arranged opposite to the connecting rod 620 at the other end of the crank 610.

More specifically, the connecting rod 620 is integrally formed by a first connecting arm 621 and a second connecting arm 622, one end of the first connecting arm 621 is rotatably connected with the other end of the crank 610 through a bearing, the other end of the first connecting arm 621 is connected with one end of the second connecting arm 622 in a staggered manner, and the other end of the second connecting arm 622 is rotatably connected with the massage head 500 through another bearing. The connecting rod 620 compensates for the deviation of the distance between the crank 610 and the massage head 500 in the axial direction by the misalignment structure between the first connecting arm 621 and the second connecting arm 622.

It should be noted that the length of the first connecting arm 621 is greater than the length of the crank 610 to avoid the crank 610 during movement, so as to avoid the second connecting arm 622 from touching the crank 610.

Since the motor 700 in the housing needs to be horizontally arranged and perpendicular to the phase massage head 500. The motor 700 has a certain length, and the motor shaft 710 passes through the fixing plate 130 and then is connected to the crank 610, and the crank 610 is connected to the connecting rod 620, which occupies space in the transverse direction (i.e. the axial direction of the motor shaft 710), so that the other end of the connecting rod 620 cannot be vertically connected to the massage head 500 when the housing with a smaller diameter is used. Here, the massage head 500 is located at the center of the circle, and the connecting rod 620 is not located at the center of the circle, so that the offset of the distance between the crank 610 and the massage head 500 in the axial direction is compensated by the offset structure of the two connecting arms in the axial direction, so that a housing with a smaller diameter can be used.

In this embodiment, the battery assembly 800 is disposed in the housing chamber and opposite to the motor 700. The crank mechanism 600 is located between the battery assembly 800 and the motor 700. Specifically, the battery assembly 800 includes two battery cells 820, and a battery holder 810 for fixing the battery cells 820. The two battery units 820 are respectively disposed at two ends of the battery support 810, and a space is provided between the two battery units 820 to allow a movable space for the connecting rod 620.

In an embodiment, the battery assembly 800 is fixed in the right half case 200, and the battery unit 820 is a cylindrical battery, and the length direction of the cylindrical battery is directed to the opening side such that the movable space extends toward the opening. Both ends of the battery support 810 are respectively provided with a fixing groove adapted to the outer contour of the columnar battery. An internal screw column 210 is provided in the right half case 200, and the battery holder 810 is fastened to the internal screw column 210 by a screw.

In order to improve the comfort of the user's hand, the fascia gun in this embodiment further includes an elastic sleeve 400 sleeved outside the left half shell 100 and the right half shell 200, so that the elastic sleeve 400 can not only buffer vibration and improve comfort, but also decorate the outer shell by the elastic sleeve 400 to cover the connecting gap between the left half shell 100 and the right half shell 200.

In addition, a plurality of reinforcing ribs are disposed on the outer side walls of the left half shell 100 and the right half shell 200, the reinforcing ribs are distributed along the circumference of the peripheral wall of the outer shell, and fixing grooves adapted to the reinforcing ribs are disposed on the inner wall of the elastic sleeve 400. The stiffening ribs may increase the strength of the housing on the one hand and may place circumferential displacement between the elastic sleeve 400 and the housing on the other hand.
