Description

Technical Field

[0001] The utility model relates to the technical field of fascia guns, in particular to a piston damping structure and a fascia gun. Background Art

[0002] A fascia gun, also known as a deep muscle fascia impactor, is a soft tissue rehabilitation tool that relaxes the soft tissues of the body through high-frequency impacts.

[0003] Currently, when the motor in the fascia gun drives the piston in the piston cylinder to reciprocate and drives the massage head to reciprocate, a damping sleeve is usually arranged in the piston cylinder to buffer the vibration force of the piston. Thus, the damping sleeve isolates the vibration force of the piston from the piston cylinder. Although this method can reduce the transmission of the vibration force of the piston to the piston cylinder, a small part of the piston vibration force will still be transmitted to the piston cylinder. Since no further components are provided between the piston cylinder and the housing of the fascia gun to buffer the vibration force, the small part of the piston vibration force received by the piston cylinder will be transmitted to the housing of the fascia gun, resulting in the vibration of the housing of the fascia gun and affecting the stable grip of the user. Therefore, the piston damping efficiency of the fascia gun is not high. Summary of the Utility Model

[0004] The utility model aims to provide a piston damping structure and a fascia gun to solve the problem of low piston damping efficiency of the fascia gun mentioned in the above background art.

[0005] The technical solution adopted by the utility model to solve the technical problem is as follows:

[0006] A piston damping structure includes a housing. The housing includes an upper housing part and a handle housing part which are integrally connected up and down. A fixed bracket is installed in the upper housing part. One end of the fixed bracket is provided with a piston cylinder, and the other end of the fixed bracket is provided with a mounting groove. A damping sleeve is sleeved in the piston cylinder. One end of the damping sleeve is set as an outward-turned lip edge. The front end face of the upper housing part is covered with a front cover. The front end face of the upper housing part and the front cover enclose a receiving cavity. The outward-turned lip edge at one end of the damping sleeve abuts against and wraps the end of the piston cylinder away from the mounting groove located in the receiving cavity. A shaft sleeve is sleeved in the damping sleeve, and a piston is sleeved in the shaft sleeve. A motor is installed in the mounting groove, and an output shaft of the motor is connected with a connecting rod which is connected with the piston.

[0007] In some embodiments, a plurality of adjacent long grooves are axially formed on the outer wall of the damping sleeve.

[0008] In some embodiments, the output shaft of the motor is connected with the connecting rod through an eccentric wheel.

[0009] In some embodiments, a battery and a circuit board are disposed inside the handle housing, the battery is electrically connected to the circuit board, and the circuit board is electrically connected to the motor.

[0010] In some embodiments, the fixed bracket is integrally formed with the piston cylinder and the mounting groove.

[0011] In some embodiments, the shock-absorbing sleeve is made of an elastic material.

[0012] In some embodiments, the front cover is provided with an opening corresponding to the piston.

[0013] The present utility model further provides a fascia gun, which includes the above-mentioned piston shock-absorbing structure and further includes a massage head; the massage head is inserted into the piston of the piston shock-absorbing structure.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In the present utility model, when the piston reciprocates in the shaft sleeve, corresponding vibration forces will be generated. The shock-absorbing sleeve in the piston cylinder isolates the piston from the piston cylinder, so the vibration forces generated by the piston are buffered by the shock-absorbing sleeve in the piston cylinder, thereby reducing the vibration forces transmitted from the piston to the piston cylinder. The front end face of the upper housing and the front cover enclose to form a receiving cavity, and the outwardly turned lip at one end of the shock-absorbing sleeve abuts against and wraps the end of the piston cylinder away from the mounting groove in the receiving cavity. Thus, the outwardly turned lip at one end of the shock-absorbing sleeve isolates the piston cylinder from the cavity wall of the receiving cavity. When the piston cylinder receives part of the vibration forces from the piston, the outwardly turned lip at one end of the shock-absorbing sleeve can buffer the vibration forces received by the piston cylinder, thereby reducing the transmission of the vibration forces of the piston cylinder to the upper housing and the front cover. The present utility model buffers and dampens the piston through the shock-absorbing sleeve inside the piston cylinder, and also buffers and dampens outside the piston cylinder through the outwardly turned lip of the shock-absorbing sleeve, so as to reduce the vibration forces received by the overall housing. Then, when the user holds the handle housing for use, the vibration feeling is low, effectively improving the smoothness of the user when using the fascia gun. BRIEF DESCRIPTION OF THE DRAWINGS

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0027] Please refer to Figures 1 to 7 As shown, the technical solutions adopted by the present utility model to solve the technical problems are as follows:

[0028] A piston damping structure 100 includes a housing 10. The housing 10 includes an upper housing part 101 and a handle housing part 102 which are integrally connected up and down. A fixed bracket 20 is installed in the upper housing part 101. One end of the fixed bracket 20 is provided with a piston cylinder 201, and the other end of the fixed bracket 20 is provided with an installation groove 202. A damping sleeve 40 is sleeved in the piston cylinder 201. One end of the damping sleeve 40 is provided with an outward-turned lip 401. The front end face of the upper housing part 101 is covered with a front cover 1011. The front end face of the upper housing part 101 and the front cover 1011 enclose a receiving cavity 1012. The outward-turned lip 401 at one end of the damping sleeve 40 abuts against and wraps the end of the piston cylinder 201 away from the installation groove 202 located in the receiving cavity 1012. A shaft sleeve 50 is sleeved in the damping sleeve 40, and a piston 60 is sleeved in the shaft sleeve 50. A motor 30 is installed in the installation groove 202. The output shaft of the motor 30 is connected with a connecting rod 302 which is connected with the piston 60.

[0029] In the piston damping structure 100 provided in this embodiment, the piston 60 is used for the massage head 200 to be inserted. When the motor 30 runs, it drives the connecting rod 302 to drive the piston 60 to reciprocate in the shaft sleeve 50. When the piston 60 reciprocates, it drives the inserted massage head 200 to reciprocate. The shaft sleeve 50 is used to provide a linear guide for the piston 60 to reciprocate. When the piston 60 reciprocates in the shaft sleeve 50, corresponding vibration forces will be generated. The damping sleeve 40 in the piston cylinder 201 isolates the piston 60 from the piston cylinder 201. Then the vibration forces generated by the piston 60 are buffered by the damping sleeve 40 in the piston cylinder 201, so as to reduce the vibration forces transmitted from the piston 60 to the piston cylinder 201. The front end face of the upper housing part 101 and the front cover 1011 enclose a receiving cavity 1012. The outward-turned lip 401 at one end of the damping sleeve 40 abuts against and wraps the end of the piston cylinder 201 away from the installation groove 202 located in the receiving cavity 1012. Thus, the outward-turned lip 401 at one end of the damping sleeve 40 isolates the piston cylinder 201 from the cavity wall of the receiving cavity 1012. Then when the piston cylinder 201 receives part of the vibration forces from the piston 60, the outward-turned lip 401 at one end of the damping sleeve 40 can buffer the vibration forces received by the piston cylinder 201, so as to reduce the transmission of the vibration forces of the piston cylinder 201 to the upper housing part 101 and the front cover 1011. The utility model buffers and dampens the piston 60 inside the piston cylinder 201 through the damping sleeve 40, and also buffers and dampens outside the piston cylinder 201 through the outward-turned lip 401 of the damping sleeve 40, so as to reduce the overall vibration forces received by the housing 10. Then when the user holds the handle housing part 102 for use, the vibration feeling is low, effectively improving the smoothness when the user uses the fascia gun 1000.

[0030] In some specific examples, the upper housing part 101 and the front cover 1011 can be integrally formed.

[0031] In some embodiments, a plurality of adjacent long grooves 402 are axially formed in the outer wall of the shock-absorbing sleeve 40 along the axis of the shock-absorbing sleeve 40.

[0032] During specific implementation: when the shock-absorbing sleeve 40 is sleeved in the piston cylinder 201, the plurality of adjacent long grooves 402 formed in the outer wall of the shock-absorbing sleeve 40 can be mutually squeezed together or mutually expanded according to the aperture size of the piston cylinder 201, so that the shock-absorbing sleeve 40 can be sleeved in the piston cylinder 201 with different apertures. Through such a setting, the shock-absorbing sleeve 40 can be applicable to be tightly fitted in the piston cylinder 201 with different apertures.

[0033] In some embodiments, the output shaft of the motor 30 is connected to the connecting rod 302 through the eccentric wheel 301.

[0034] During specific implementation: when the output shaft of the motor 30 rotates, it drives the eccentric wheel 301 to rotate. When the eccentric wheel 301 rotates, it drives the connecting rod 302 to perform a linear reciprocating motion, so that the connecting rod 302 drives the piston 60 to perform a reciprocating motion in the bushing 50. Through such a setting, the motor 30 can effectively drive the piston 60 to perform a reciprocating motion through the connecting rod 302.

[0035] In some embodiments, a battery 70 and a circuit board 80 are arranged inside the handle housing portion 102. The battery 70 is electrically connected to the circuit board 80, and the circuit board 80 is electrically connected to the motor 30.

[0036] During specific implementation: the battery 70 is used to provide power to the circuit board 80, and the circuit board 80 delivers electric energy and controls the motor 30. Through such a setting, the motor 30 can be powered on and controlled.

[0037] In some embodiments, the fixed bracket 20, the piston cylinder 201, and the mounting groove 202 are integrally formed.

[0038] During specific implementation: the fixed bracket 20, the piston cylinder 201, and the mounting groove 202 are integrally formed, so that the fixed bracket 20 can firmly hold the motor 30 through the mounting groove 202, and the fixed bracket 20 can firmly hold the piston 60 through the mounting cylinder. Through such a setting, the firmness of the fixed bracket 20 for holding the motor 30 and the piston 60 can be improved.

[0039] In some embodiments, the shock-absorbing sleeve 40 is made of an elastic material.

[0040] During specific implementation: the shock-absorbing sleeve 40 is made of an elastic material, and the elastic material can be a material with elastic functions such as silicone or rubber. Through such a setting, the shock-absorbing sleeve 40 made of an elastic material can be in the piston cylinder 201

[0041] In some embodiments, the front cover 1011 is provided with an opening 10111 corresponding to the piston 60.

[0042] In specific implementation: an opening 10111 is formed in the front shell for the piston 60 to extend from the inside of the upper shell portion 101 to the outside of the upper shell portion 101, so that the massage head 200 can be inserted into the piston 60 from the opening 10111. Through such a setting, the massage head 200 can be inserted into the piston 60 of the upper shell portion 101.

[0043] The present utility model further provides a fascia gun 1000, which includes the above-mentioned piston damping structure 100 and also includes a massage head 200; the massage head 200 is inserted into the piston 60 of the piston damping structure 100. The motor 30 in the piston damping structure 100 drives the piston 60 to reciprocate, and when the piston 60 reciprocates, it drives the inserted massage head 200 to reciprocate, so that when the massage head 200 reciprocates, it vibrates and massages the user.
