For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0035] In order to solve the problem that the massage device in the prior art has relatively simple movements, and the massage head is subject to resistance from the massaged part of the human body during the movement, making it difficult to achieve a good massage effect, the present application provides a massage device that can perform a good massage and improve the massage experience.

[0036] Reference Figure 1 and Figure 2 , shows a massage device according to a first embodiment of the present application, which comprises a housing 10 , a driving member 20 installed in the housing 10 , and a massage member 30 transmission-connected to the driving member 20 .

[0037] An activity space 12 is provided on the housing 10 , and the activity space 12 at least penetrates through a side wall of one side of the housing 10 , so as to communicate with the external environment.

[0038] The massage component 30 is located in the activity space 12 and is rotatably connected to the housing 10 via the first pivot 54. The massage component 30 can rotate relative to the housing 10 under the drive of the driving component 20. During the rotation of the massage component 30, the massage portion 32 of the massage component 30 can extend out of the activity space 12 of the housing 10 to reach the external environment to massage the part of the human body close to the housing 10.

[0039] In the massage device of this embodiment, the movable space 12 in the housing 10 provides sufficient space for the rotation of the massage component 30, so that a greater force can be exerted on the massaged part, thereby achieving a good massage effect.

[0040] The outer contour of the housing 10 can be designed according to its application scenario, for example, it can be cylindrical, block-shaped, disc-shaped, tree-branch-shaped, etc.

[0041] In this embodiment, if Figure 2 As shown, the housing 10 is a double-layer structure, including an inner housing 10a and an outer housing 10b covering the entire inner housing 10a. The inner housing 10a is made of a hard material such as plastic, metal, wood, etc.; the outer housing 10b is made of a soft material such as silicone, rubber, etc. The inner housing 10a not only provides support for the outer housing 10b, but also provides a receiving space for installing the driving member 20. The outer housing 10b is used to directly contact the massaged part, and preferably has a smooth outer surface, so that the massage device as a whole has high strength and a comfortable use experience.

[0042] Preferably, the inner shell 10a is formed into two parts by injection molding, and then assembled together by buckles, screws, etc., which facilitates the assembly of the components inside the inner shell 10a, such as the driving member 20. After the inner shell 10a and the components inside the inner shell 10a are assembled together, the outer shell 10b is integrally covered with the inner shell 10a by secondary injection molding, and the integral outer shell 10b is conducive to the waterproof and dustproof of the massage device.

[0043] In other embodiments, the inner shell 10a may be molded as one piece; in this case, components mounted inside the inner shell 10a are arranged in a mold, and then the inner shell 10a is injection molded.

[0044] Alternatively, the housing 10b may be molded into two or more parts and then assembled together; in this case, the housing 10 is detachable so as to be used for replacing the parts inside thereof, which is beneficial to the maintenance of the massage device.

[0045] The structural shape of the inner shell 10a can be the same as that of the outer shell 10b, so the shell 10 has two different layers at any position. Alternatively, the inner shell 10a can be different from the outer shell 10b in a local area, so the local area of ​​the shell 10 can be a single layer, that is, there is no hard inner shell 10a.

[0046] Preferably, the portion of the housing 10 surrounding the activity space 12 is a double-layer structure, which has sufficient strength to support the swing of the massage component 30 .

[0047] A gap is reserved between the outer surface of the massage component 30 and the inner surface of the housing 10 surrounding the activity space 12 ; the gap enables the massage component 30 to rotate in the activity space 12 without interfering with the housing 10 .

[0048] In this embodiment, the housing is longitudinally long, the activity space 12 is located in the middle portion of the housing 10, and the activity space 12 is closed at both ends in the longitudinal direction of the housing 10. The activity space 12 extends through opposite sides of the housing 10, thereby forming openings at two opposite sides (e.g., the top side and the bottom side) of the housing 10, respectively, so that the activity space 12 communicates with the external environment.

[0049] The housing 10 forms two support arms on opposite sides (eg, left and right sides) of the activity space, and both ends of the first pivot 54 are respectively connected to the two support arms.

[0050] In other embodiments, the activity space 12 may be a blind hole extending through only one side of the housing 10, for example, only through the top side of the housing 10. In this case, the depth of the activity space 12 is less than the thickness of the housing 10. The massage device with a blind hole is more suitable for massaging the surface of the human body, such as the waist, neck, etc.

[0051] Specifically, the outer periphery of the massage component 30 is provided with a plurality of radially extending massage parts 32, at least one of which extends out of the activity space 12. In this embodiment, some of the plurality of massage parts 32 extend out of two opposite sides of the activity space 12, such as the top side and the bottom side.

[0052] In this embodiment, refer to Figure 3-5As shown, the massaging member 30 is integrally constructed as an impeller, which includes a hub 31 and protrusions. The hub 31 is provided with a hole for connecting the first pivot 54 at its central portion, a plurality of protrusions extend radially outward from the hub 31, and a plurality of massaging parts 32 are formed at free ends of the plurality of protrusions.

[0053] Optionally, the protrusion can be a blade, a convex column or a convex hull. The protrusion can be distributed on the entire outer surface of the hub 31. Preferably, the protrusion is integrally formed with the hub 31, for example by injection molding. Alternatively, the protrusion can be formed separately and then assembled to the hub 31 by bonding.

[0054] like Figure 3-5 , an embodiment in which the protrusion is a blade 33 is shown, and the blade 33 and the hub 31 can be formed separately and then assembled together, or can be integrally formed as one component. The hub 31 is rotatably connected to the support arm of the housing 10 through the first pivot 54, and the blades 33 are arranged around the hub 31 and spaced apart from each other in the circumferential direction. Each blade 33 has an inner end connected to the hub 31 and a free end away from the hub 31; the free end of each blade 33 is configured as the massage part 32 of the massage member 30.

The housing 10 also has a branch 19, and the branch 19 extends from one end of the activity space 12 close to the driving member 20 to the top of the massage member 30 in a curved manner, and a second vibration member 52 is provided in the branch 19, and the second vibration member 52 and the first vibration member 50 respectively massage different parts of the human body through vibration.

[0062] Preferably, again refer to Figure 2The massage device further includes a control member 56, such as a control circuit board installed in the housing 10. The control member 56 is electrically connected to the driving member 20, the first vibration member 50 and the second vibration member 52, and is used to control their operations according to the user's instructions, such as controlling the vibration frequency of the first vibration member 50 and the second vibration member 52, and controlling the speed and direction of the driving member 20. In specific applications, both the first vibration member 50 and the second vibration member 52 can use vibration motors.

[0063] The massage device further includes a battery 58 disposed in the housing 10, the battery 58 being electrically connected to the circuit board 56; the battery 58 provides power to the driving member 20, the first vibration member 50, and the second vibration member 52 through the circuit board 56. Preferably, the battery 58 is a rechargeable battery, and a corresponding charging interface 59 may be disposed at the rear end of the housing 10 to connect an external power source to charge the battery 58.

[0064] Reference Figure 9-11 , shows a massage device according to a second embodiment of the present application, which has the same structure as the first embodiment except for the transmission unit.

[0065] In this embodiment, if Fig.10 and Fig.11 As shown, the transmission unit includes a gear unit 241 and a pulley unit 242; the gear unit 241 includes a first gear 243 and a second gear 244 meshing with each other. Preferably, the first gear 243 and the second gear 244 are bevel gears; the pulley unit 242 includes a driving wheel 245, a driven wheel 246, and a belt 247 interconnecting the driving wheel 245 and the driven wheel 246. The first gear 243 is connected to the rotating shaft 21 of the driving member 20, the second gear 244 is connected to the driving wheel 245, the driven wheel 246 is connected to the hub 31 of the massage member 30, and the hub 31 is rotatably connected to the housing 10 through the first pivot 54.

[0066] During use, the driving member 20 is started, thereby driving the massage member 30 to rotate around the first pivot 54 through the transmission unit, and the blades 33 of the massage member 30 can be rotated to be completely accommodated in the activity space 12, or can be rotated to make the massage part 32 extend out of the activity space 12 to reach the external environment. In other words, the massage part 32 of the blade 33 can extend out of the activity space 12 in turn to massage the human body part close to the outer surface of the housing 10.

[0067] In this embodiment, the driving wheel 245 and the second gear 244 are coaxial, and the driven wheel 246 and the hub 31 are coaxial; the hub 31 and the driven wheel 246 are rotatably connected to the housing 10 via the first pivot 54, and the second gear 244 and the driving wheel 245 are rotatably connected to the housing 10 via the second pivot 55. Through the transmission unit, long-distance power transmission can be achieved, so the driving member 20 and the massage member 30 can be set in different positions, for example, the massage member 30 is in the activity space 12, and the driving member 20 is in the inner cavity of the housing 10.

[0068] It should be understood that there may be other forms of transmission structures between the driving member 20 and the massage member 30, or multiple transmission structures may be combined, as long as the massage member 30 can be driven to rotate.
