[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] It should be noted that, in the description of this application, if the terms "first", "second", etc. appear, "first" and "second" are only used to facilitate the description of different components or names, and cannot be understood as indicating or implying a sequential relationship, relative importance, or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" appears in the full text, its meaning is that it includes three parallel solutions, taking "A and / or B as an example", including Solution A, or Solution B, or a solution that satisfies both A and B.

[0048] Please refer to Figures 1 to 5 The embodiment of the present application provides a physical therapy device 100. The physical therapy device 100 includes a housing 10, a massage structure 20 and a light source 30. The housing 10 has a mounting cavity 11 and an opening 12 connected to the mounting cavity 11. The massage structure 20 is arranged corresponding to the opening 12, and at least a part of the massage structure 20 protrudes from the housing 10. The light source 30 is located in the mounting cavity 11, and the light source 30 is arranged facing the opening 12.

[0049] The massage structure 20 is arranged corresponding to the opening 12, which means that at least a portion of the massage structure 20 faces the opening 12 and can be massaged in the direction of the opening 12 ( Figure 5 The S direction in the figure refers to the opening direction), and the massage structure 20 has a portion overlapping with the opening 12, that is, the massage structure 20 can at least partially cover the opening 12. Part of the massage structure 20 can extend into the opening 12; or, the massage structure 20 is completely located outside the housing 10 and does not extend into the opening 12, and the massage structure 20 only covers the opening 12 on the outer side of the housing 10.

[0050] Specifically, the massage structure 20 can relax muscles, smooth wrinkles, etc. by directly contacting the skin and applying local pressure to the skin. In some embodiments, the massage structure 20 can be a ball. When the massage structure 20 is set as a ball, a part of the ball is located in the installation cavity 11, and another part of the ball protrudes from the opening 12 outside the housing 10. The ball can roll in the opening 12, thereby achieving rolling massage on the skin.

[0051] In other embodiments, the massage structure 20 may also be a protrusion fixed to the housing 10. For example, the massage structure 20 is completely located outside the housing 10. The massage structure 20 may be hemispherical, cylindrical, or the like.

[0052] The light source 30 is arranged facing the opening 12, so that the light emitted by the light source 30 can be emitted through the opening 12. In the embodiment of the present application, the massage structure 20 is arranged as a light-transmitting member, so that the massage structure 20 can avoid blocking the light, and the light emitted by the light source can be emitted through the massage structure 20, thereby performing light therapy on the user.

[0053] The technical solution in the embodiment of the present application can achieve the dual functions of massage and phototherapy by using the massage structure 20 and the light source 30, and the two can be performed simultaneously, which can assist each other, save the time of physical therapy, and greatly improve the user experience. At the same time, since the massage structure 20 itself is made of a light-transmitting material, the light source 30 can use the light-transmitting characteristics of the massage structure 20 itself to emit light out of the shell 10, so there is no need to set other transparent areas on the shell 10 for the light source 30, which reduces the processing difficulty of the shell 10. Moreover, in this process, the part of the phototherapy basically coincides with the part of the massage, and the two can fully cooperate and promote each other to achieve better results. In addition, the massage structure 20 can play a dual role, both as a massage body and as a light-transmitting structure for phototherapy. In this way, the setting of components is reduced, the compactness between components is improved, and the size of the whole machine is reduced, so the physical therapy device 100 can be set to a smaller size, which is convenient for users to hold and improves the user experience.

[0054] Please refer to Figure 3 , Figure 5 , Figures 7 to 9 In some embodiments, a focusing portion 161 is provided near the opening 12 of the housing 10. The focusing portion 161 is arranged around the opening 12 and extends into the mounting cavity 11. The light source 30 includes a light emitting element 31, and the light emitting element 31 is located in the focusing portion 161. In this embodiment, the focusing portion 161 can be connected to the edge of the opening 12; or, the focusing portion 161 is at a small distance from the opening 12 in the direction of the opening 12. The focusing portion 161 is made of a non-light-transmitting material. By covering the light emitting element 31 inside, the light emitted by the light emitting element 31 can be prevented from diffusing to the surroundings, thereby achieving a focusing effect, guiding the light to the opening 12 and the massage structure 20, so as to better concentrate the effect on the massage area.

[0055] The light source 30 includes one or more light-emitting elements 31, and the light-emitting element 31 refers to an LED (light-emitting diode) that can emit light of a specific wavelength, such as red light, infrared light, blue light, etc. When multiple light-emitting elements 31 are provided, the multiple light-emitting elements 31 have the same color, or the multiple light-emitting elements 31 each have a different color. Taking red light as an example, red light can promote cell regeneration and collagen production, and therefore is widely used in phototherapy products.

[0056] Furthermore, the light source 30 further includes a lamp board 32, which is disposed facing the opening 12, and the light emitting element 31 is located on the side of the lamp board 32 facing the opening 12, and the end of the light focusing portion 161 abuts against the lamp board 32. On one hand, after the light focusing portion 161 abuts against the lamp board 32, the light emitting element 31 can be completely covered inside to prevent the light from radiating to the surroundings; on the other hand, the light focusing portion 161 can limit the lamp board 32 to prevent the lamp board 32 from moving toward the side where the opening 12 is located.

[0057] Furthermore, the inner wall of the installation cavity 11 is provided with a first limiting structure, and the first limiting structure abuts against the side of the lamp board 32 facing the opening 12, thereby limiting the movement of the lamp board 32 toward the opening 12. In this embodiment, the first limiting structure may refer to the focusing portion 161, so that the structure of the focusing portion 161 is fully utilized to achieve limiting, and no other additional structures are required, thereby reducing the difficulty of processing and the setting of parts. Of course, in some embodiments, the first limiting structure may also be a dot-shaped protrusion or annular protrusion provided on the inner wall of the installation cavity 11.

[0058] Furthermore, in order to prevent the light board 32 from moving in a direction away from the opening 12, a second limiting structure 13 is provided on the inner wall of the mounting cavity 11, and the second limiting structure 13 abuts against the side of the light board 32 away from the opening 12. The second limiting structure 13 may specifically include a plurality of protrusions, and the plurality of protrusions are spaced around the light board 32. Alternatively, the second limiting structure 13 is an annular protrusion. In this embodiment, the first limiting structure and the second limiting structure 13 jointly clamp the light board 32 to prevent the light board 32 from moving along the axial direction of the housing 10.

[0059] When the lamp board 32 is assembled from bottom to top, in order to facilitate the lamp board 32 to cross the second limiting structure 13, the side of the second limiting structure 13 facing away from the opening 12 can be set as a guiding inclined surface or a guiding curved surface.

[0060] The edge of the lamp board 32 is basically in contact with the inner wall of the installation cavity 11 or is matched with a small gap, so the lamp board 32 is basically kept stationary in the radial direction of the housing 10. Of course, the lamp board 32 can also be fixed by the clamping effect of the first limiting structure and the second limiting structure 13. Alternatively, the lamp board 32 can also be bonded to either the first limiting structure or the second limiting structure 13.

[0061] Please refer to it again Figure 3 and Fig. 9 In addition, in order to prevent the light board 32 from rotating, the light board 32 is also installed and positioned during the installation process. Therefore, the inner wall of the installation cavity 11 is further provided with a guide groove 14, the guide groove 14 extends in the direction of the opening 12, and the edge of the light board 32 is provided with a guide protrusion 321, and the guide protrusion 321 is slidably matched with the guide groove 14. During installation, the guide protrusion 321 is inserted into the guide groove 14 and moves along the guide groove 14 until the light board 32 crosses the second limiting structure 13 and is clamped between the first limiting structure and the second limiting structure 13. At this time, the guide protrusion 321 is still located in the guide groove 14, preventing the light board 32 from rotating relative to the housing 10.

[0062] Please refer to it again Figure 3 , Figure 5 and Fig. 9Specifically, in some embodiments, the housing 10 includes a first shell 15 and a second shell 16 distributed along the direction of the opening 12. The first shell 15 is hollow with two ends penetrating through it, and one end of the first shell 15 forms the opening 12. The second shell 16 includes a light collecting portion 161 and a main shell 162 that are spaced apart from each other. The main shell 162 is spaced apart from each other on the outer periphery of the light collecting portion 161. One end of the light collecting portion 161 is connected to the main shell 162 through an annular convex edge 163. The length of the light collecting portion 161 is less than that of the main shell 162. The lamp board 32 is located in the main shell 162 and is arranged corresponding to the end of the light collecting portion 161 that is away from the annular convex edge 163. The inner wall of the main shell 162 is provided with a guide groove 14, and the guide groove 14 extends along the axial direction of the main shell 162 from the end of the main shell 162 that is away from the opening 12. During installation, the lamp board 32 is located from the end of the main shell 162 that is away from the opening 12 and slides into the main shell 162 along the guide groove 14. Since the light focusing portion 161 is spaced apart from the main housing 162 , the inner diameter of the light focusing portion 161 can be set to be smaller, thereby achieving a better light focusing effect.

[0063] In the above description, the first shell 15 and the second shell 16 are both hollow cylindrical structures, such as a circular cylinder, an elliptical cylinder, or a square cylinder.

[0064] In some embodiments, a portion of the massage structure 20 is located in the first shell 15, and a portion of the massage structure 20 is located in the light focusing portion 161. The aperture of the light focusing portion 161 is smaller than the diameter of the massage structure 20, so that the massage structure 20 can be limited from escaping from the light focusing portion 161 in a direction away from the opening 12. In this embodiment, taking the massage structure 20 as a spherical shape as an example, a small portion of the massage structure 20 is accommodated in the light focusing portion 161, and the upper end opening of the light focusing portion 161 is covered, so that all light is emitted from the massage structure 20. Optionally, the upper end opening edge of the light focusing portion 161 is a spherical surface, and the spherical surface is respectively connected to the annular protrusion and the inner wall of the light focusing portion 161. The spherical surface can better match the spherical massage structure 20.

[0065] The setting of the annular convex edge 163 enables the second shell 16 to have a larger end surface. When the end of the first shell 15 abuts against the annular convex edge 163, the second shell 16 can provide a larger support area, making the support more stable. Fig. 9 and Fig.10 Optionally, the annular convex edge 163 is provided with an annular positioning groove 172, and the first shell 15 is provided with a positioning rib 173 to be plugged into the annular positioning groove 172. Further, the first shell 15 and the second shell 16 are bonded, and the annular positioning groove 172 and the positioning rib 173 are bonded.

[0066] In some embodiments, the housing 10 includes a plurality of shells distributed in sequence along the direction of the opening 12, each of which is hollow and together forms the installation cavity 11, and two adjacent shells are bonded by an adhesive. The bonding method does not require punching, thereby avoiding damage to the appearance of the entire device. In addition, in other embodiments, two adjacent shells can also be fixed by ultrasonic welding.

[0067] Please refer to Figure 6 Optionally, a glue-containing gap 171 is formed on the end faces of the two adjacent shells that are connected. The glue-containing gap 171 can accommodate more glue and improve the connection stability of the two adjacent shells. The glue-containing gap 171 is an annular gap extending circumferentially around the shell. In order to form the glue-containing gap 171, the end of the shell can be arranged in a stepped surface, some of the step surfaces of the two adjacent shells are in contact, and other step surfaces are spaced apart to form the glue-containing gap 171. Of course, a groove can also be directly opened on the end face of one of the shells to form the glue-containing gap 171.

[0068] Please refer to it again Figure 5 Specifically, the housing 10 includes four shells distributed in sequence along the direction of the opening 12, and the four shells are respectively a first shell 15, a second shell 16, a third shell 18 and a fourth shell 19. The first shell 15, the second shell 16 and the third shell 18 are all hollow structures with both ends penetrated, and the fourth shell 19 is a hollow structure with one end open and the other end closed, and the third shell 18 is connected to the open end of the fourth shell 19. In this way, the hollow areas of the first shell 15, the second shell 16, the third shell 18 and the fourth shell 19 jointly form the installation cavity 11. By splitting the housing 10 into a plurality of separately arranged shells, the processing difficulty of a single shell is simplified, and each shell can be designed into a different shape.

[0069] The aperture of the opening 12 on the first shell 15 is smaller than the diameter of the massage structure 20, thereby preventing the massage structure 20 from detaching from the opening 12. A light source 30 is arranged in the second shell 16 so that the light source 30 can be emitted close to the opening 12 of the first shell 15. The third shell 18 is used as a decorative piece and can adopt different colors, such as red, to enhance the overall appearance. At the same time, the setting of the third shell 18 also makes the overall structure have a relatively large length, which is convenient for holding. The fourth shell 19 can have a larger lateral dimension and serve as a handle for holding. The lateral direction refers to the direction perpendicular to the direction of the opening 12. In addition, please refer to Figure 1 and Fig.11 The fourth shell 19 is provided with a main control board 50, a button 40 and a battery 70. The main control board 50 and the battery 70 are located inside the fourth shell 19. The main control board 50 is electrically connected to the light board 32. When the button 40 is pressed, it can trigger the main control board 50 to control the conduction and disconnection of the light-emitting element 31.

[0070] In some embodiments, in two adjacent shells, the end of one shell is inserted into the other shell to form an inner-outer shell structure, which can facilitate lateral positioning and installation.

[0071] In some embodiments, one of the two adjacent shells is provided with an annular positioning groove 172, and the end of the other shell is plugged into the annular positioning groove 172. In this way, positioning and installation can be facilitated. Specifically, a positioning rib 173 is provided at the end of the other shell to be plugged into the annular positioning groove 172, or the entire end of the other shell is inserted into the annular positioning groove 172. For the specific structure, please refer to the connection between the first shell 15 and the second shell 16 mentioned above. Of course, the second shell 16 and the third shell 18, as well as the third shell 18 and the fourth shell 19 can also be plugged in respectively by means of the positioning rib 173 and the annular positioning groove 172.

[0072] In some embodiments, the housing 10 is in the shape of a hollow strip with one end closed and the other end having an opening 12. The opening 12 is centrally disposed and provided with a massage structure 20. The massage structure 20 is a ball and is movably connected to the housing 10 so as to be able to roll in the opening 12. The long strip-shaped housing 10 is convenient to hold, and the other end of the housing 10 is closed to prevent dust and water vapor from entering the interior. The massage structure 20 is centrally disposed at the end of the housing 10, which is in line with the user's usage habits and is ergonomically designed.

[0073] Furthermore, the physiotherapy device 100 also includes a vibrator 80 disposed on the main control board 50. The vibrator 80 can generate vibrations after being powered on, driving the housing 10 to vibrate, thereby achieving vibration massage and stimulation on the skin.

[0074] Furthermore, the physiotherapy device 100 further includes a top cover 60, which covers the end of the housing 10 having the massage structure 20, and the top cover 60 and the housing 10 can be connected by a convex snap connection or a magnetic connection.
