Massage ball with planetary gear

[0001] The present invention relates to a massage ball equipped with a planetary gear, and more particularly, to a massage ball equipped with a planetary gear capable of rotating a heater cover while reducing wear and noise generated inside the massage ball by providing a ring gear on the inner surface of a heater cover and a gear assembly including a planetary gear inside the heater cover.

[0002] A spinal thermal massage device is a device designed to relieve acute or chronic pain that occurs in the muscles and nerve tissues of the spinal area. Recently, various types of spinal thermal massage devices have been developed.

[0003] A spinal thermal massage device can be moved along the body to improve blood circulation or relieve temporary muscle tension. Furthermore, the heat generated by the device can be used to apply thermal stimulation to painful areas, improving blood flow and alleviating pain.

[0005] However, conventional massage balls with heaters have the following problems. Conventional massage balls with heaters are equipped with aluminum parts, SUS pins, and Teflon components, and their outer surfaces can rotate. Conventional massage balls with heaters have the problem of noise generated by wear and tear between parts as the outer surface of the massage ball rotates.

[0006] Specifically, a conventional massage ball equipped with a heater has a problem in that when the outside of the massage ball rotates, the SUS pin and Teflon parts rotate in contact with the aluminum part, which may cause wear between different materials, resulting in noise.

[0007] Additionally, a conventional massage ball equipped with a heater transfers heat generated from the heater through SUS fins, Teflon parts, etc. Specifically, heat generated from the heater can be transferred through a path such as the aluminum inner part of the massage ball - SUS fins or Teflon parts - aluminum outer part.

[0080] In addition, by forming the heater cover (110), the planetary gear (140), and the gear carrier (150) with the same material, the transfer efficiency of heat generated from the heater (111) can be improved.

[0081] Specifically, since the heater cover (110), the planetary gear (140), and the gear carrier (150) are formed of the same material and have the same thermal conductivity, it is possible to prevent the heat transfer efficiency from being reduced due to different thermal conductivities between the parts.

[0082] According to an embodiment of the present invention, the bolt (190) may also be made of the same material as the heater cover (110), the planetary gear (140), and the gear carrier (150). This makes it possible to improve the efficiency of heat transfer generated from the heater (111).

[0087] As the gear carrier (150) is fixed to the massage module plate (10), the gear carrier (150) can support the planetary gear (140) while acting as a shaft of the planetary gear (140).

[0088] The above planetary gear (140) can be engaged with the ring gear (112) of the heater cover (110) while being assembled to the gear carrier (150), and when the ring gear (112) rotates, the planetary gear (140) rotates in the same direction to support the heater cover (110).

[0089] In this way, as the ring gear (112) of the heater cover (110) engages with the planetary gear (140) of the gear carrier (150), the heater cover (110) can rotate with respect to the gear carrier (150).

[0090] According to an embodiment of the present invention, a plurality of planetary gears (140) may be mounted on the gear carrier (150). Referring to FIG. 8, one side of the gear carrier (150) is set as an XY plane, and the center of the gear carrier (150) is set as a center point (O(0,0)).

[0091] When the center points (A, B, C) of the plurality of planetary gears (140) are respectively derived, the plurality of planetary gears (140) can be arranged on the gear carrier (150) so that the sum of the X-axis coordinates formed by the center points (A, B, C) of the plurality of planetary gears (140) is O, and the sum of the Y-axis coordinates formed by the center points (A, B, C) of the plurality of planetary gears is O.

[0092] Specifically, a plurality of the planetary gears (140) can be mounted on the gear carrier (150) so that the resultant force on the X-axis becomes 0 and the resultant force on the Y-axis becomes 0 based on the center point (O(0,0)) of the gear carrier (150).

[0093] More specifically, in FIG. 8, the sum of the X-axis coordinates a1, b1, c1 formed by each of the center points (A, B, C) of the plurality of planetary gears (140) may be 0. In addition, in FIG. 8, the sum of the Y-axis coordinates a2, b2, c2 formed by each of the center points (A, B, C) of the plurality of planetary gears (140) may be 0.

[0094] In Fig. 8, it is described that three planetary gears (140) are mounted on the gear carrier (150), but this is not limited thereto. According to an embodiment of the present invention, as shown in Fig. 9, two planetary gears (140) may be mounted on the gear carrier (150), or four planetary gears (140) may be mounted on the gear carrier (150).

[0095] Even if the number of the planetary gears (140) mounted on the gear carrier (150) is changed, a plurality of the planetary gears (140) can be mounted on the gear carrier (150) so that the resultant force on the X-axis becomes 0 and the resultant force on the Y-axis becomes 0 based on the center point (O(0,0)) of the gear carrier (150).
