[0038] Currently, for the percussion massagers on the market, whether the massage head is pulled out or inserted into the piston, the motor can usually start normally. When the massage head is pulled out from the piston and not turned off, the movement of the movement mechanism drives the piston to make high-frequency reciprocating movements. Most pistons are metal parts, and the high-frequency reciprocating movement of the piston without the massage head may cause great impact damage to the human body. Especially when children come into contact with it, it can be started casually, and serious accidents may even cause physical disability. Due to the risk of accidental start-up to the consumer group, how to improve the safety of the percussion massager has become an urgent problem to be solved.

[0039] The present utility model proposes a percussion massager.

[0040] Please refer to Figures 1 to 7, in an embodiment of the present utility model, the fascia gun 100 includes a housing 110, a movement assembly 120, a massage head 130, and a conduction assembly 140. An accommodation cavity 110a is formed in the housing 110, and an opening 110b communicating with the accommodation cavity 110a is provided on the surface of the housing 110. The movement assembly 120 includes a driver 121 and a main control board 123 that are arranged in the accommodation cavity 110a and electrically connected to each other. A piston 122 is movably arranged at the opening 110b and is drivingly connected to the driver 121. The massage head 130 is detachably connected to the piston 122 and has a connected state and a separated state relative to the piston 122. The conduction assembly 140 includes a trigger and a switch controller. The trigger is arranged on the massage head 130, and the switch controller is correspondingly arranged on the piston 122 and is connected to the anti-misoperation circuit of the main control board 123.

[0041] When the massage head 130 and the piston 122 are in the separated state, the trigger and the switch controller are disconnected, and the switch controller disconnects the anti-misoperation circuit on the main control board 123, that is, the main control board 123 is powered off and thus cannot control and start the driver 121. At this time, even if the switch button of the fascia gun 100 is accidentally touched, the piston 122 will not move; when the massage head 130 and the piston 122 are in the connected state, the trigger triggers the switch controller, and the switch controller conducts the anti-misoperation circuit of the main control board 123, that is, the main control board 123 is powered on. At this time, pressing the switch button of the fascia gun 100 can normally start the driver 121, and the piston 122 drives the massage head 130 to move. As can be seen from the above, by setting the conduction assembly 140, when the massage head 130 is pulled out of the fascia gun 100, even if the switch button is accidentally touched, the driver 121 cannot be started, and the piston 122 cannot cause harm to the human body, effectively improving the safety of the fascia gun 100 and eliminating potential risks.

[0042] In an embodiment, the trigger is a conduction plate 141, and the switch controller is an elastic needle plate 142. The elastic needle plate 142 includes a circuit board 1421 and at least two elastic needles 1422. The elastic needles 1422 are spaced on the circuit board 1421. At least two contact sections 1411 are provided on the conduction plate 141. In the connected state, the contact sections 1411 are in one-to-one abutting connection with the elastic needles 1422 to conduct the anti-misoperation circuit.

[0043] As Figures 3 to 5As shown, in an embodiment of the present utility model, the trigger member is a conduction plate 141, and the switch controller is an elastic needle plate 142. Specifically, the elastic needle plate 142 includes a circuit board 1421 and at least two elastic needles 1422. The multiple elastic needles 1422 are arranged at intervals on the circuit board 1421. Contact segments 1411 are provided on the conduction plate 141 corresponding to each elastic needle 1422. The multiple elastic needles 1422 are respectively in abutting connection with the multiple contact segments 1411 to form a loop, so as to conduct the anti-mis-touch circuit of the main control board 123. In this solution, the number of elastic needles 1422 is set to 3. The 3 contact segments 1411 are in a central annular structure on the conduction plate 141 and are respectively in corresponding abutting connection with the elastic needles 1422. The elastic needle 1422 located at the center of the circuit board 1421 and the other two elastic needles 1422 can be respectively connected through the conduction plate 141 to form a loop. The purpose is to prevent the disconnection between the elastic needle 1422 and the contact segment 1411 when the massage head 130 is skewed. Setting multiple elastic needles 1422 can ensure the connection stability and avoid the shutdown of the fascia gun 100 during use.

[0044] In an embodiment, the trigger member is a magnetic member 143, and the switch controller is a Hall element 144. In the connected state, the magnetic member 143 is arranged close to the Hall element 144, and the Hall element 144 senses the magnetic field of the magnetic member 143 to conduct the anti-mis-touch circuit with the main control board 123.

[0045] As Figures 6 to 7 As shown, in an embodiment of the present utility model, the trigger member is a magnetic member 143, and the switch controller is a Hall element 144. Specifically, the trigger member can adopt a common magnet block. The Hall element 144 is arranged on the piston 122. When the massage head 130 is connected to the piston 122, the trigger member is arranged close to the Hall element 144. When the Hall element 144 senses the magnetic field of the magnetic member 143, it conducts the anti-mis-touch circuit of the main control board 123. At this time, the massage head 130 and the piston 122 of the fascia gun 100 are in a connected state, and the main control board 123 is powered on. Pressing the switch button of the fascia gun 100 can start the driver 121. When the massage head 130 is pulled out of the piston 122, the switch controller cannot sense the magnetic field of the magnetic member 143, and thus disconnects the anti-mis-touch circuit of the main control board 123, avoiding the user accidentally touching the switch button to start the driver 121. The elastic needle 1422 is prone to disconnection when the massage head 130 is skewed. Setting the magnetic member 143 and the Hall element 144 is more stable than the elastic needle 1422. Both methods can achieve the anti-mis-touch function, and the actual product can be set and selected according to specific requirements.

[0046] In one embodiment, a slot 122a is provided on one side of the piston 122 facing the massage head 130. The switch controller is disposed in the slot 122a. The massage head 130 includes a massage portion 131 and a connecting portion 132. The triggering member is disposed on the side of the connecting portion 132 away from the massage portion 131. The connecting portion 132 is inserted into the slot 122a so that the triggering member triggers the switch controller.

[0047] As Figures 1 to 8 shown, in one embodiment of the present utility model, a slot 122a is provided at one end of the piston 122 facing the massage head 130. Specifically, the massage head 130 includes a massage portion 131 and a connecting portion 132. The massage portion 131 is used for contacting and massaging the human body. One end of the connecting portion 132 is connected to the massage portion 131. The triggering member is disposed on the side of the connecting portion 132 away from the massage head 130. The switch controller is disposed in the slot 122a of the piston 122. When the connecting portion 132 is inserted into the slot 122a of the piston 122, the triggering member can trigger the switch controller to conduct the anti-mis-touch circuit of the main control board 123. By providing the slot 122a on the piston 122, the installation of the switch controller and the insertion of the massage head 130 can be facilitated at the same time. The slot 122a can restrict the insertion direction of the connecting portion 132 so that the triggering member is accurately docked with the switch controller.

[0048] In one embodiment, the conduction assembly 140 further includes a first bracket 145 and a connecting wire 146. The first bracket 145 is disposed on the bottom wall of the slot 122a. The switch controller is disposed on the side of the first bracket 145 away from the bottom wall of the slot 122a. One end of the connecting wire 146 is connected to the switch controller, and the other end of the connecting wire 146 passes through the bottom wall of the slot 122a and is connected to the main control board 123.

[0049] As Figure 3 、 Figure 4 、 Figure 6 and Figure 7 shown, in one embodiment of the present utility model, the conduction assembly 140 further includes a first bracket 145 and a connecting wire 146. Specifically, the first bracket 145 is attached to the bottom wall of the slot 122a. The switch controller is disposed on the side of the first bracket 145 away from the bottom wall of the slot 122a. When the connecting portion 132 of the massage head 130 is inserted into the slot 122a, the triggering member can trigger the switch controller on the first bracket 145. One end of the connecting wire 146 is connected to the switch controller. A through hole is provided through the bottom wall of the slot 122a. The other end of the connecting wire 146 passes through the through hole and is connected to the main control board 123 in the accommodation cavity 110a. The connecting wire 146 can be made of an anti-bending cable and the length is reserved with a margin so that the connecting wire 146 can be repeatedly bent and extended when the piston 122 moves at high frequency, ensuring the stability of the connection.

[0050] In one embodiment, an installation groove 132a is provided on the side of the connecting portion 132 away from the massage portion 131, and the triggering member is disposed in the installation groove 132a;

[0051] And / or, the massage head 130 further includes a second bracket 133. The second bracket 133 is disposed in the installation groove 132a, and the triggering member is disposed on the second bracket 133 and faces the switch controller.

[0052] As Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown in

[0053] In one embodiment of the present utility model, an installation groove 132a is provided on the side of the connecting portion 132 of the massage head 130 away from the massage portion 131. The installation groove 132a is used for installing the triggering member. Disposing the triggering member in the installation groove 132a can reduce the occupation of the piston 122 slot 122a by the connecting portion 132, so as to reduce the overall length of the piston 122 and further reduce the overall volume of the fascia gun 100. And disposing the triggering member in the installation groove 132a can improve the tightness of the internal components of the fascia gun 100, improve space utilization and reduce the difficulty of assembling the components of the fascia gun 100.

[0053] Furthermore, the massage head 130 further includes a second bracket 133. Please refer to Figure 6 and Figure 7 . A buckle is provided on the second bracket 133, and a card slot is provided on the connecting portion 132. The magnetic member 143 is fixed on the second bracket 133, and the buckle of the second bracket 133 is snapped into the card slot of the connecting portion 132. The second bracket 133 is fixed to one end of the connecting portion 132 away from the massage head 130, so that the Hall element 144 is exactly within the magnetic field of the magnetic member 143. Of course, when the conduction plate 141 is adopted, a bracket with a corresponding shape can also be provided to fix the conduction plate 141 on the connecting portion 132, which is not specifically limited herein.

[0054] In one embodiment, the massage head 130 further includes a silica gel sleeve 134. A first limiting groove 132b is provided on the connecting portion 132, and the silica gel sleeve 134 is embedded in the first limiting groove 132b. The silica gel sleeve 134 abuts against the inner wall of the slot 122a and is at least partially clamped between the side wall of the limiting groove and the end face of the piston 122.

[0055] As Figure 3 and Figure 6As shown, in an embodiment of the present utility model, the massage head 130 further includes a silica gel sleeve 134. Specifically, the connecting portion 132 of the massage head 130 is cylindrical and the outer surface is provided with a first limiting groove 132b. The slot 122a of the piston 122 is a circular groove. The silica gel sleeve 134 is embedded in the first limiting groove 132b. When the connecting portion 132 is inserted into the slot 122a, the outer surface of the silica gel sleeve 134 is in interference fit with the inner wall of the slot 122a, improving the connection tightness between the massage head 130 and the piston 122.

[0056] One end of the silica gel sleeve 134 close to the massage head 130 extends outwards in a direction away from the connecting portion 132 to form an annular step portion. One side of the step portion abuts against the side wall of the first limiting groove 132b, and the other side of the step portion abuts against the end face of the piston 122. That is, the side wall of the first limiting groove 132b and the end face of the piston 122 clamp the step portion of the silica gel sleeve 134, preventing the end face of the piston 122 from contacting the massage head 130 and causing wear, and at the same time avoiding the silica gel sleeve 134 moving along the axis of the connecting portion 132 and affecting the connection stability. Moreover, the silica gel sleeve 134 also has a certain waterproof function to protect the conduction component 140 inside the piston 122.

[0057] In an embodiment, an external thread 1321 is provided on the connecting portion 132, and an internal thread matching the external thread 1321 is provided on the inner wall of the slot 122a, so that the massage head 130 is threadedly connected to the piston 122.

[0058] As Figure 7 shown, in an embodiment of the present utility model, an external thread 1321 is provided on the outer surface of the connecting portion 132, and an internal thread (not shown) is correspondingly provided on the inner wall of the slot 122a of the piston 122. The connecting portion 132 is screwed into the slot 122a to threadedly connect the massage head 130 and the piston 122. It can be understood that using threaded connection can improve the connection tightness. In the previous solution, the structure with interference of the silica gel sleeve 134 is adopted. After long-term use or repeated plugging and unplugging, the silica gel will fatigue and lose elasticity, resulting in the loosening of the massage head 130, affecting the user experience. Threaded connection has higher stability, is not easy to loosen, and does not need to worry about the problem of silica gel fatigue.

[0059] In an embodiment, the massage head 130 further includes a silica gel ring 135. A second limiting groove 132c is provided on the connecting portion 132 at an interval from the external thread 1321. The silica gel ring 135 is embedded in the second limiting groove 132c, so that the side wall of the second limiting groove 132c and the end face of the piston 122 clamp the silica gel ring 135.

[0060] As Figure 7As shown, in an embodiment of the present utility model, in order to improve the effect of threaded connection, the massage head 130 further includes a silicone ring 135. An annular second limiting groove 132c is provided on the connecting portion 132. The silicone ring 135 is embedded in the second limiting groove 132c, and the side wall of the second limiting groove 132c abuts against one side of the silicone ring 135. When the connecting portion 132 is screwed into the slot 122a, the end face of the piston 122 abuts against the other side of the silicone ring 135 to cause elastic deformation of the silicone ring 135. The elastic force generated by the elastic deformation of the silicone ring 135 causes the external thread 1321 to bite tightly with the internal thread of the piston 122, preventing the massage head 130 from loosening, effectively improving the fastening effect of the massage head 130 and enhancing the user experience.

[0061] In an embodiment, the movement assembly 120 further includes a battery disposed in the accommodation cavity 110a. The driver 121 includes a motor 1211, an eccentric wheel 1212, and a bearing connecting rod 1213. The battery is electrically connected to the motor 1211 and the main control board 123. The output end of the motor 1211 is connected to the eccentric wheel 1212. One end of the bearing connecting rod 1213 is rotatably connected to the eccentric wheel 1212, and the other end of the bearing connecting rod 1213 is rotatably connected to the piston 122.

[0062] As Figure 1 As shown, in an embodiment of the present utility model, the movement assembly 120 further includes a battery (not shown). The driver 121 includes a motor 1211, an eccentric wheel 1212, a bearing connecting rod 1213, and a motor bracket 1214. The motor bracket 1214 is fixed in the accommodation cavity 110a.
