Description

Technical field:

[0001] The invention belongs to the field of massage equipment, and in particular relates to a fascia therapy gun, which adopts a modular design, is easy to install and repair, and can reduce noise. Background technology:

[0002] There are many public information and finished products of existing physiotherapy guns, also known as massage guns, tendon guns, etc., which can be roughly divided into two categories: one is electromagnetic drive, which has the characteristics of long stroke and high noise; the other is motor drive, which has a relatively short stroke, low noise, and obvious vibration during operation. Both have their own advantages and disadvantages, which is also the reason why the industry cannot choose between the two solutions. As disclosed in patent application No. 201520043026.4, a new manual massager is disclosed, including a shell composed of a gun body and a gun handle, and also including an eccentric shaft, wherein an eccentric shaft mounting seat is arranged in the gun body, a massage connection hole is opened at one end of the gun body, the eccentric shaft is mounted on the eccentric shaft mounting seat and extends from the massage connection hole, a massage head is installed at the extended end of the eccentric shaft, a motor is installed in the gun handle, an eccentric bearing is installed at the output end of the motor, the eccentric bearing is movably connected to the eccentric shaft, a plastic upper cover is installed on the upper part of the motor, the eccentric bearing is installed on the plastic upper cover, and a plastic lower cover is installed at the lower part of the motor as a means of reducing noise.

[0042] like Figure 6 The movement module 2 includes a motor 21, an eccentric block 22, a connecting rod 23, an impact shaft 24, a movement frame 25, a guide sleeve 26, a pressure cover 27 and a bearing 28; the movement frame 25 has an upward and open installation cavity 251, and a muzzle 252 is formed at one end; the motor 21 is locked on the bolt seat of the installation cavity 251 through an end cover or a motor frame 211, and a shock-absorbing pad 29 is arranged between the bolt seat to reduce the vibration of the motor 21 when it is working and transmitted to the movement frame 25.

[0043] The eccentric block 22 is formed of heavy metal, and has a main shaft hole 221, an eccentric sector block 222 and an eccentric shaft 223. The eccentric sector block 222 and the eccentric shaft 223 are separated on both sides of the main shaft hole 221, and the center of gravity overlaps with the center of the main shaft hole to maintain the center of gravity balance and reduce the vibration caused by eccentric rotation; and the weight of the eccentric sector block 222 and the eccentric shaft 223 constitutes a flywheel effect with a higher moment of inertia, thereby increasing the driving force of the eccentric shaft 223.

[0044] The eccentric block is locked on the output shaft of the motor 21 by means of the main shaft hole 221, and the connecting rod 23 is driven by the eccentric shaft 223.

[0045] The middle section of the impact shaft 24 is slidably constrained at the muzzle end by the guide sleeve 26, and the guide sleeve 26 is locked at the outer end of the muzzle 252 by means of the pressure cover 27; when the movement module 2 is nested in the main body shell 11 with the help of the movement frame 25, the guide sleeve 26 at its front end can be embedded in the muzzle sleeve 121 of the front cover to form a support for the outer end of the guide sleeve 26, so that the concentricity of the reciprocating operation of the impact shaft 24 can be guaranteed; the massage head 4 is inserted at the end of the impact shaft 24 to act on the human body.

[0046] Furthermore, a rubber sleeve 261 is provided on the outer cover of the guide sleeve 26, and the rubber sleeve 261 isolates the guide sleeve 26 from the muzzle 252 and the pressure cover 27, as well as the guide sleeve 26 and the muzzle sleeve 121 of the front cover. The rubber sleeve 261 is used to eliminate the assembly gap and reduce the impact force and reaction force of the impact shaft 24 transmitted to other components.

[0047] The power module 3 is arranged in the handle 15, and the handle 15 and the support handle cover 14 form a detachable plug-in; and the bolt seat of the support handle cover 14 passes through the main body shell 11, and is locked with the movement frame in the movement module 2 by screws, forming an assembly locking structure among the three.

[0048] Furthermore, the assembly structure between modules is solved. Among them:

[0049] like Figure 5 , assembly slots 111 are correspondingly provided on both sides of the inner wall of the main body shell 11, and convex rails 253 are correspondingly formed on the edges of both sides of the movement frame 25.

The handle cover 14 is embedded upward from the belly of the main body shell 11 and locked with the movement frame 25 to form an assembly positioning structure among the three, and finally the closed back cover 13 is installed.

[0050] The movement frame 25 is formed with a battery embedding seat 254 at the bottom of the installation cavity 251, corresponding to the motor projection area, and two to three electrode sheets 255 are arranged on the edge of the battery embedding seat 254, and the electrode sheets 255 are electrically connected to the motor 21; the main body shell 11 is formed with a through hole corresponding to the battery embedding seat, and the support handle cover 14 is formed with a nest 141 corresponding to provide support for the power module 3; the power module 3 is locked into one with the handle 15, and can be inserted and locked by the lock tongue 142 on the support handle cover. The handle 15 and the power module 3 can be removed by unlocking the lock tongue 142, and the lock tongue 142 adopts a conventional push-type sliding pin structure.

[0051] More specifically, the handle 15 includes a handle tube 151 and a bottom cover 152. The power module 3 is embedded in the handle tube 151 with the help of an external packaging shell 31, and the bottom cover 152 is directly locked on the packaging shell 31. In the space between the packaging shell 31 and the bottom cover 152, a circuit board 32 for battery management is arranged, and a charging port 33 and a switch 34 are correspondingly arranged on the bottom cover 152. At the edge joint of the packaging shell 31 and the bottom cover 152, an indicator light ring 35 is arranged to indicate the charging state or the power usage state. The upper part of the packaging shell 31 protrudes out of the handle tube 151 to form an exposed section, and an electrode 36 is arranged on the top of the exposed section. With the help of the exposed section, after passing through the nesting 141 of the handle cover and the through hole of the main shell 11 in sequence, it is docked with the battery embedding seat 254 in the movement module, and forms an electrical connection with the electrode sheet 255 on the edge of the battery embedding seat to supply power to the motor and the control circuit board.
