The physiotherapy device includes a shell 1, a circuit board 2, a battery 3, a ball 4 and a micro-current electrode 41. Optionally, the shell 1 has an interior containing a cavity, and the cavity can accommodate the circuit board 2, the battery 3 and the ball 4 to achieve covering protection. The battery 3 is installed in the cavity, and the battery 3 is electrically connected to the circuit board 2. The battery 3 can provide working power for the micro-current electrode 41. The ball 4 is rotatably installed in the cavity, and a through hole is provided on the shell 1. Part of the ball 4 extends out of the through hole, and the part of the ball 4 extending out of the through hole can contact the skin of the human body. The micro-current electrode 41 is installed on the ball 4, and the micro-current electrode 41 is electrically connected to the circuit board 2. The micro-current electrode 41 can perform electrotherapy on the skin.

Each microcurrent electrode 41 is arranged in a long strip shape, and the two ends of each microcurrent electrode 41 are respectively connected to the two ends of the ball 4; the width of each microcurrent electrode 41 gradually decreases from the middle position to the left and right ends.

During the rotation of the ball 4, the microcurrent electrode 41 located thereon can perform electrotherapy on the skin, which helps to improve the uniformity of the treatment effect of the microcurrent electrode 41 on the skin at different positions.

If the detected skin quality is poor, the treatment time can be adjusted according to the skin quality.

[0059] See also Figure 7 Another embodiment of the present application further provides a physiotherapy device. The difference between the physiotherapy device provided by this embodiment and the physiotherapy device provided by the above embodiment is that: the physiotherapy device also includes a massage ball 6 that is rollingly mounted on the shell 1, and the massage ball 6 is spaced apart from the ball 4. This structure can massage the skin by setting the massage ball 6. Among them, the number of massage balls 6 and the ball 4 can both be multiple, and can be adjusted accordingly according to actual needs, and is not the only limitation here. The massage ball 6 is a universal ball. When the physiotherapy device moves in any direction, the massage ball 6 can roll on the skin, which is conducive to reducing the resistance of the physiotherapy device when it moves on the skin.

[0060] In one embodiment, the massage ball 6 is mounted on the housing 1 through a floating structure, specifically, the massage ball 6 is connected to the middle housing 12 through a spring. When the massage ball 6 is subjected to an external force, it can float through the elastic expansion and contraction of the spring, thereby improving the contact degree between the massage ball 6 and the skin, so that it can be adapted to different concave positions of the head, such as the face, the lower jaw, the neck, etc.

[0061] In one embodiment, the ball 4 can also be installed on the housing 1 through a floating structure, specifically, the ball 4 is connected to the middle housing 12 through a spring, the spring is made of a conductive material, and the spring can be electrically connected to the circuit board 2, so that the micro-current electrode 41 on the ball 4 can be electrically connected to the circuit board 2. When the ball 4 is subjected to an external force, it can float through the elastic expansion and contraction of the spring, and the contact degree between the ball 4 and the skin is increased, so that it can be adapted to different concave positions of the head, such as the face, the lower jaw, the neck, etc.

[0062] In one embodiment, see Figure 7 , the multiple massage balls 6 and the multiple rolling balls 4 are divided into two groups, and the two groups of massage balls 6 and the two groups of rolling balls 4 are respectively installed on the left and right sides of the housing 1, that is, arranged on both sides of the control switch 21. Among them, the massage balls 6 and the rolling balls 4 on the left side are of the same size, the massage balls 6 and the rolling balls 4 on the right side are of the same size, and the massage balls 6 on the left side are of the same size as the massage balls 6 on the right side; or, the size of the massage balls 6 on the left side is larger than the size of the massage balls 6 on the right side.

[0063] In one embodiment, the sizes of the massage sphere 6 and the rolling ball 4 on the left side are different, and / or the sizes of the massage sphere 6 and the rolling ball 4 on the right side are different. With this structure, the massage spheres 6 and the rolling balls 4 of different sizes can achieve adaptive fit with the skin through the spring, thus improving the physical therapy effect on the skin.

[0064] In one embodiment, the housing 1 is made of a flexible material, and the housing 1 can be bent under the action of an external force, that is, the massage ball 6 on the left and the massage ball 6 on the right, and the ball 4 on the left and the ball 4 on the right can be moved closer to or farther from each other under the bending action of the housing 1. In this structure, the bending angle of the housing 1 can be changed by bending the housing 1, and then the position of each massage ball 6 and each ball 4 can be adjusted, so that it can be adapted to skin positions with different degrees of concavity.

[0065] In one embodiment, the multiple massage balls 6 and the multiple balls 4 on the left are arranged at intervals, and the interval positions between the multiple massage balls 6 and the multiple balls 4 are light-transmitting positions. The multiple light sources 51 on the left are arranged at intervals, and the multiple light sources 51 on the left are respectively arranged in alignment with the multiple light-transmitting positions on the left. Similarly, the multiple massage balls 6 and the multiple balls 4 on the right are arranged at intervals, and the interval positions between the multiple massage balls 6 and the multiple balls 4 are light-transmitting positions. The multiple light sources 51 on the right are arranged at intervals, and the multiple light sources 51 on the right are respectively arranged in alignment with the multiple light-transmitting positions on the right. This structure aligns the multiple light sources 51 with the multiple light-transmitting positions, avoids the multiple massage balls 6 and the multiple balls 4 from blocking the multiple light sources 51, thereby improving the light output intensity of the multiple light sources 51, and thereby improving the phototherapy effect.

[0066] In one embodiment, the physiotherapeutic device may further include a detection probe mounted on the housing 1, and the detection probe may be electrically connected to the circuit board 2. The detection probe may detect the skin, and the detection probe may issue instructions to the micro-current electrode 41 and / or the light source 51 according to the detected skin condition, and may adjust the current strength of the micro-current electrode 41 and / or the light intensity of the light source 51 according to different skin conditions, thereby improving the intelligent physiotherapy effect of the physiotherapeutic device.

[0067] The physiotherapy apparatus provided in another embodiment of the present application has the same other corresponding structures as the physiotherapy apparatus provided in the above embodiment, which will not be repeated here.

[0068] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
