Abstract
Description
Technical Field
[0001] The utility model relates to the field of massagers, and more particularly to a fascia massager. Background Art
[0002] A fascia massager, 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. Specifically, a special high-speed motor inside it is used to drive the "gun head" to retract and extend back and forth, generating high-frequency vibrations that act on the deep muscles, achieving the effects of reducing local tissue tension, relieving pain, and promoting blood circulation.
[0003] Currently, in order to generate the effect of telescopic vibration in existing fascia massagers, an eccentric wheel is usually used to connect the piston. By rotating the eccentric wheel, the piston is made to generate a reciprocating telescopic stroke, thereby realizing vibration. However, since the weight of the existing eccentric wheel is uniform, when connecting the connecting rod externally, because the connecting rod itself also has a certain weight, the weight at the position where the eccentric wheel is connected to the connecting rod is actually greater than the weight at other positions of the eccentric wheel. Therefore, when the eccentric wheel drives the connecting rod to start rotating, due to the inconsistent weight of the eccentric wheel, in addition to driving the connecting rod to perform telescopic vibration, there will also be a left-right swing in other directions, resulting in a poor holding feel for the user when holding. Summary of the Utility Model
[0004] In order to solve the above problems, the utility model provides a fascia massager, including a driving component. The driving component is arranged inside the machine shell. One end of the driving component is connected with a holding part, and the other end is connected with a massage body through a piston component. The driving component includes a driving motor and an eccentric wheel. The driving motor can drive the eccentric wheel to rotate. The eccentric wheel includes a fixed part power-connected to the driving motor, an inertial expansion part formed along one side of the fixed part, and a connecting part formed along the other side of the fixed part. An eccentric shaft is arranged on the connecting part for connecting the connecting rod. The connecting rod is connected with the piston component, and a cutting part for reducing weight is also arranged on the connecting part.
[0005] Furthermore, the cutting part is a circular cut along the circumferential surface between the fixed part of the eccentric wheel and the eccentric shaft.
[0006] Furthermore, the number of the cutting parts is two, and they are symmetrically distributed with the axis between the fixed part of the eccentric wheel and the eccentric shaft as the axis.
[0007] Furthermore, the driving component further includes a bracket. The bracket is fixedly installed inside the machine shell. The driving motor is fixedly installed on one side of the bracket. The driving end of the driving motor passes through the bracket and is connected with the eccentric wheel.
[0008] Furthermore, a rotary bearing is arranged between the connecting rod and the eccentric shaft.
[0009] Furthermore, the piston assembly includes a piston rod and an annular bushing. The bushing is fixed inside the housing, and the piston rod passes through the bushing and is connected to the massage body.
[0010] Furthermore, the bushing is tightly sleeved on the outer wall of the piston rod.
[0011] Furthermore, a battery pack and a control circuit board are arranged inside the holding part. The battery pack, the control circuit board and the drive motor are electrically connected, and a button connected to the control circuit board is arranged on the holding part.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] Compared with the prior art, in this application, by partially cutting off a part of the eccentric wheel and the connecting rod to form a cutting part, the mass of the lower part of the center line of the eccentric wheel can be reduced, so as to form a vibration reduction balance when connected to the connecting rod, so that the eccentric wheel will drive the connecting rod to perform eccentric rotation. When driving the piston assembly to perform telescopic vibration, the left and right swing caused by the eccentric rotation can be minimized, which not only ensures the overall output force, but also improves the poor hand feeling of the whole machine caused by the swing during holding.

The terms used in this specification in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0028] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0029] The preferred embodiments of the present utility model will be further described below in conjunction with the accompanying drawings. In conjunction with Figures 1 to 4 As shown, a fascia massager includes a driving assembly 100. The driving assembly 100 is disposed within a housing 10. One end of the driving assembly 100 is connected to a holding portion 300, and the other end thereof is connected to a massage body 20 through a piston assembly 200. The driving assembly 100 can drive the piston assembly 200 and the massage body 20 to perform telescopic vibration. The driving assembly 100 includes a driving motor 110 and an eccentric wheel 120. The driving motor 110 can drive the eccentric wheel 120 to rotate. The eccentric wheel 120 includes a fixed portion 121 power-connected to the driving motor 110, an inertial expansion portion 122 formed along one side of the fixed portion 121, and a connecting portion 123 formed along the other side of the fixed portion 121. An eccentric shaft 124 is disposed on the connecting portion 123 for connecting a connecting rod 130. The connecting rod 130 is used to connect the piston assembly 200. When the driving motor 110 drives the eccentric wheel 120 to rotate, the eccentric wheel 120 will drive the connecting rod 130 to perform eccentric rotation, thereby driving the piston assembly 200 to perform telescopic vibration. A cutting portion 125 for reducing weight is further disposed on the connecting portion 123. Compared with the prior art, in the present application, by partially cutting the part of the eccentric wheel 120 and the connecting rod to form the cutting portion 125, the mass of the lower part of the center line of the eccentric wheel 120 can be reduced, so as to form a vibration damping balance when connected to the connecting rod 130, so that when the eccentric wheel 120 drives the connecting rod 130 to perform eccentric rotation, thereby driving the piston assembly 200 to perform telescopic vibration, the left and right swing caused by the eccentric rotation can be minimized, which not only ensures the overall output force but also improves the poor hand feeling of the whole machine caused by the swing.
[0030] Furthermore, on the basis of the above embodiment, in conjunction with Figures 3 to 5 As shown, the cutting portion 125 is an arc-shaped circular cut along the circumferential surface between the fixed portion 121 of the eccentric wheel 120 and the eccentric shaft 124.
[0031] Furthermore, on the basis of the above embodiment, in conjunction with Figures 3 to 5As shown, the number of the cutting parts 125 is two, symmetrically distributed with the axis between the fixing part 121 of the eccentric wheel 120 and the eccentric shaft 124. Thus, it can be ensured that after the connecting part 123 is removed by cutting, the left and right weights are consistent with the axis between the fixing part 121 of the eccentric wheel 120 and the eccentric shaft 124. In this way, the left and right swing caused by eccentric rotation can be further reduced, thereby further improving the holding feel.
[0032] Furthermore, on the basis of the above embodiments, in combination with Figure 2 and Figure 6 As shown, the drive assembly 100 further includes a bracket 140. The bracket 140 is fixedly installed inside the housing 10. The drive motor 110 is fixedly installed on one side of the bracket 140. The drive end of the drive motor 110 passes through the bracket 140 and is connected to the eccentric wheel 120. Since the bracket 140 is fixedly installed with the housing 10 and the drive motor 110 is fixed on one side of the bracket 140, when the eccentric wheel 120 drives the connecting rod 130 to perform eccentric rotation, the influence of vibration on the drive motor 110 can be reduced, ensuring the stability of the operation of the drive motor 110.
[0033] Furthermore, on the basis of the above embodiments, in combination with Figure 2 and Figure 6 As shown, a rotary bearing 150 is provided between the connecting rod 130 and the eccentric shaft 124. The rotary bearing 150 plays a role in steering. When the eccentric wheel 120 drives the connecting rod 130 to perform eccentric rotation, the connecting rod 130 can provide good telescopic vibration.
[0034] Furthermore, on the basis of the above embodiments, in combination with Figure 2 and Figure 6 As shown, the piston assembly 200 includes a piston rod 210 and an annular bushing 220. The bushing 220 is fixedly installed inside the housing 10. The piston rod 210 passes through the bushing 220 and is connected to the massage body 20. When the eccentric wheel 120 drives the connecting rod 130 to perform eccentric rotation, the piston rod 210 can perform telescopic vibration inside the bushing 220.
[0035] Furthermore, on the basis of the above embodiments, in combination with Figure 2 and Figure 6 As shown, the bushing 220 is tightly sleeved on the outer wall of the piston rod 210. In this way, when the eccentric wheel 120 drives the connecting rod 130 to perform eccentric rotation, the left and right swing of the piston rod 210 inside the bushing 220 can be further reduced.
[0036] Furthermore, on the basis of the above embodiments, as shown in Figure 2As shown, a battery pack 310 and a control circuit board 320 are disposed inside the holding portion 300. The battery pack 310, the control circuit board 320 and the drive motor 110 are electrically connected. The battery pack 310 is used to supply electrical energy to the control circuit board 320 and the drive motor 110. The control circuit board 320 is used to control the start / stop and rotation speed of the drive motor 110. A key 330 connected to the control circuit board 320 is disposed on the holding portion 300. The user can control the control circuit board 320 by operating the key 330.
[0037] Details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.
