Description

Technical Field

[0001] The present application relates to the technical field of muscle physiotherapy, and in particular to an electric physiotherapy device for relieving muscle pain. Background Art

[0002] In the field of modern sports rehabilitation and physical therapy, electric physiotherapy devices, especially fascia gun-type physiotherapy devices, have become important tools for relieving muscle pain and promoting blood circulation. Traditional fascia guns act on muscle tissue through high-frequency vibrations to help relieve lactic acid accumulation, muscle soreness and pain after exercise. There are also various types of fascia guns on the market, which play a better therapeutic role in relieving muscle pain by pressing the skin with a vibrating massage head.

[0003] During vibration therapy, if the operator applies too much force, the combination of high-frequency vibration and mechanical pressure can easily lead to tearing of muscle fibers and rupture of capillaries. Especially during high-intensity use or operation by non-professional users, the risk of such injuries increases significantly, and in severe cases, it may cause subcutaneous congestion or deep tissue inflammation.

[0004] In order to solve this problem, there are many technical solutions for controlling the output of fascia guns in the prior art, such as the Chinese patent document CN115006229A, which records a method for controlling the output of fascia guns. By setting multiple pressure sensors, the pressure change rate of the massage head is determined according to the pressure collected by the massage head, thereby controlling the output of the massage head. When the pressure change at the massage head is too large, the output intensity is reduced or the output is stopped to ensure the safety of the fascia gun. However, this solution can only control the change in the output intensity of the fascia gun itself, and does not provide a protection mechanism when the operator uses too much force.

[0005] On the other hand, most existing equipment uses fixed massage heads, which are prone to breeding bacteria when in contact with different skin areas when used by multiple people. Frequent manual disinfection is inefficient and relies on the operator's consciousness, which poses a prominent risk of cross-infection in gyms, physical therapy clinics and other scenarios. For this reason, a variety of disinfection schemes have been proposed in the prior art. For example, Chinese patent document CN218458316U records a massage head component of a fascia gun, which disinfects the surface of the massage head when it is quickly removed from the inner cavity of the massage head by setting a disinfection lamp. However, in physical application scenarios such as our Weimei Experience Store, it is more necessary to disinfect the massage head of the fascia gun before turning the table.

[0006] However, there is an urgent need in the prior art for an electric physiotherapy device for relieving muscle pain that can minimize damage caused by excessive pressure during operation of a vibration therapy device and can be disinfected in a timely manner to avoid the risk of cross infection when used by multiple people.

[0032] Figure 6 A schematic diagram of the structural position relationship of the pressure lock unit 308 of the overpressure prevention structure 3; Figure 7 for Figure 6 The schematic diagram of the local enlarged structure at A shown in FIG. As a preferred embodiment, Figure 6 , 7As shown, the pressure lock unit 308 includes a slider A3081, a round head column 3082, a control spring 3083, a slider B3084, a fixed column 3085, a threaded rod 3086 and an adjusting knob 3087. The interior of the limit slider 305 is provided with an inner cavity, and the side wall of the guide rail 304 is provided with a circular groove. The slider A3081 is slidably connected in the inner cavity of the limit slider 305, and the side wall of the slider A3081 is fixedly connected with a round head column 3082. The round head end of the round head column 3082 extends into the circular groove of the guide rail 304. The limit slider 305 A slider B3084 is slidably connected in the inner cavity, a control spring 3083 is fixedly connected between the slider B3084 and the slider A3081, a fixing column 3085 is fixedly connected to the side wall of the limit slider 305, one end of the fixing column 3085 passes through the guide rail 304 and slides with the guide rail 304, a threaded rod 3086 is connected to the internal thread of the fixing column 3085, one end of the threaded rod 3086 extends to the side wall of the slider B3084 and is rotatably connected to the slider B3084, and an adjusting knob 3086 is fixedly connected to the other end of the threaded rod 3086 087, the control spring 3083 is in a compressed state. Through the present technical solution, the control spring 3083 in the compressed state can make the round head end of the round head column 3082 press against the circular groove of the guide rail 304, so as to realize the damping locking function. When the downward pressing vibration therapy is performed, as the downward pressing force of the grip gradually increases, the buffer spring 306 is continuously compressed. When the downward pressing force is greater than the friction force of the round head column 3082 pressing against the circular groove, the round head column 3082 will be squeezed and retracted, thereby separating from the circular groove, so that the limit slider 305 is unlocked and slid, and the pressure is reduced by sliding. As can be seen from the above description, by setting the anti-overpressure structure 3, the function of controlling the downward pressure can be realized when pressing down, and when the downward pressure exceeds a certain threshold, the function of automatically unlocking and sliding decompression can be realized. At the same time, the adjusting knob 3087 can be manually rotated to drive the threaded rod 3086 to rotate and move, thereby driving the slider B3084 to move. The movement of the slider B3084 can control the compression amount of the control spring 3083, thereby realizing the function of adjusting the resistance threshold, and the threshold of unlocking and decompression can be flexibly adjusted according to different usage scenarios.

Since the sponge column 207 is in contact with the surface of the spherical massage head 202, the alcohol disinfectant can be automatically applied to the surface of the spherical massage head 202 during the rolling of the spherical massage head 202, thereby achieving the effect of automatic sterilization and disinfection. No additional power source is required, and the massage head is particularly suitable for muscle therapy for multiple people, effectively avoiding the breeding of bacteria and cross-infection caused by the contact of the massage head with the skin of different people. At the same time, the heat conduction effect can be achieved through the setting of the heat dissipation fins 1021, thereby assisting the heat dissipation of the power motor 107 and avoiding overheating due to long-term use. During the flow of the alcohol disinfectant in the inner cavity of the copper tube 1022, it can further absorb heat and assist in heat dissipation.
