Description

Massage ball with sealing structure

[0001] The present invention relates to a massage ball having a sealing structure, and more particularly, to a massage ball having a sealing structure capable of improving the efficiency of heat transfer generated from a heater by applying the sealing structure to a heater cover having a heat transfer material such as graphene oil or grease applied thereon.

[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.

[0004] A spinal thermal massage device includes a heat-generating massage ball that applies heat stimulation while applying pressure to the user. The center of the massage ball may include a PTC heater that heats when current is applied.

[0005] However, massage balls equipped with conventional heaters have the following problems: Massage balls equipped with conventional heaters transfer heat generated by the heater through SUS fins, Teflon parts, air layers, etc.

[0006] 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, or the air layer - aluminum outer part. However, when heat is transferred through SUS fins, Teflon parts, air layers, etc. in this way, there is a problem in that heat transfer efficiency is reduced due to low thermal conductivity between the parts.

[0007] Specifically, although the thermal conductivity of the SUS fin (16.8) is high, there is a problem of reduced heat transfer efficiency due to the low thermal conductivity of air (0.025) and Teflon (0.20).

[0008] Meanwhile, conventional massage balls equipped with heaters are fitted with injection-molded outer covers. However, attaching an injection-molded outer cover to the outside of a massage ball can lead to discomfort for the user due to the increased massage sensation. Furthermore, attaching an injection-molded outer cover to the outside of a massage ball can lead to heat loss due to the holes required for attaching the outer cover.

[0009] The present invention is intended to solve the above-described problem, and more specifically, relates to a massage ball equipped with a sealing structure capable of improving the efficiency of heat transfer generated from a heater by applying a sealing structure to a heater cover on the inside of which a heat transfer material such as graphene oil or grease is applied.

Specifically, the heater cover (110) may be provided with a rotation shaft (116) fitted to the inside of the rotation member (20), and the heater (111) may be provided inside the rotation shaft (116).

[0072] According to an embodiment of the present invention, the heater (111) may be formed of various types of heaters that heat when current is applied, and the heater (111) may be formed of a PTC heater. However, in order to improve the heat generation specifications of the heater (111), it is preferable that the heater (111) be formed of a ceramic heater.

[0073] Referring to FIG. 7, the heater cover (110) according to an embodiment of the present invention may include a side shielding portion (113) that covers the other side of the side wall (112) so that the other side of the internal space of the heater cover (110) is shielded from the other side of the side wall (112).

[0074] The other side shielding portion (113) may be a surface covering the other side of the heater cover (110), and as shown in FIG. 7, the other side shielding portion (113) may be manufactured integrally with the side wall (112). The other side shielding portion (113) may be made of the same material as the side wall (112). By manufacturing the other side shielding portion (113) and the side wall (112) integrally, the other side of the heater cover (110) can be shielded.

[0075] According to an embodiment of the present invention, the side wall (112) of the heater cover (110) can be continuously extended along the circumference of the heater cover (110), and the other side of the side wall (112) can be shielded through the other side shielding portion (113).

[0076] In addition, by sealing and shielding one side of the heater cover (110) through the first cover (130) and the first sealing member (140), both one side and the other side of the heater cover (110) can be shielded. This prevents the heat transfer material applied to the inside of the heater cover (110) from leaking.

[0077] According to an embodiment of the present invention, the rotating shaft (116) having the heater (111) inside may be manufactured integrally with the other side shielding part (113) and made of the same material.

[0078] Referring to Fig. 3, since the rotation shaft (116) and the other side shielding part (113) are made of the same material and are manufactured as one piece, heat generated from the heater (111) provided inside the rotation shaft (116) can be efficiently transferred.

[0079] Referring to FIG. 8, the outer cover (120) according to an embodiment of the present invention may include a side wall cover (121) coupled to the outside of the side wall (112) of the heater cover (110), and a side shielding cover (122) connected to the side wall cover (121) and covering the other side of the side wall (112) so that the other side of the internal space of the heater cover (110) is shielded.

[0080] The side wall cover (121) extends along the circumferential direction of the heater cover (110), and the side wall cover (121) can cover the side wall (112) of the heater cover (110).

[0081] The other side shielding cover (122) may be a surface covering the other side of the side wall cover (121). The other side shielding cover (122) covers the other side of the side wall (112) so that the other side of the internal space of the heater cover (110) is shielded, and the other side of the internal space of the heater cover (110) can be shielded through the other side shielding cover (122).

[0082] Referring to Fig. 7, the side wall cover (121) and the other side shielding cover (122) may be manufactured as one piece. In addition, the side wall cover (121) and the other side shielding cover (122) may be made of the same material.

[0083] Referring to Fig. 8, when the other side of the internal space of the heater cover (110) is shielded through the other side shielding cover (122), the other side shielding portion (113) of the heater cover (110) may not be formed.

[0084] Specifically, even if the other side shielding portion (113) of the heater cover (110) is not formed as shown in FIG. 8, if the other side shielding cover (122) is provided on the outer cover (120), the other side of the heater cover (110) is shielded through the other side shielding cover (122), thereby preventing leakage of the heat transfer material applied to the inside of the heater cover (110).

[0085] However, in order to shield the other side of the heater cover (110) more firmly, it is preferable to cover the other side of the heater cover (110) through the other side shielding cover (122) of the outer cover (120) while the other side shielding portion (113) is formed on the heater cover (110).

[0086] According to an embodiment of the present invention, the user's massage sensation can be improved by providing the other side shielding cover (122) to the outer cover (120). If the other side of the heater cover (110) is made of an injection-molded material, the user may feel uncomfortable as the massage sensation becomes stronger due to the injection-molded material.

[0087] However, if the other side of the heater cover (110) is covered with the other side shielding cover (122) made of a soft material on the outer cover (120), the user's massage sensation can be improved through the other side shielding cover (122) of the outer cover (120).

[0088] Although the other side shielding portion (113) of the heater cover (110) is described as being manufactured integrally with the side wall (112), it is not limited thereto. Referring to FIG. 9, the other side shielding portion (113) according to an embodiment of the present invention may be made of the same material as the side wall (112) and may be coupled to the side wall (112). Specifically, the other side shielding portion (113) may be made of a separate member from the side wall (112) and may be coupled to the side wall (112).

[0089] In addition, although the other side shielding cover (122) of the outer cover (120) has been described as being manufactured integrally with the side wall cover (121), it is not limited thereto. Referring to FIG. 9, the other side shielding cover (122) according to an embodiment of the present invention may be made of the same material as the side wall cover (121) and may be coupled to the side wall cover (121). Specifically, the other side shielding cover (122) may be made of a separate member from the side wall cover (121) and may be coupled to the side wall cover (121).

[0090] Referring to Fig. 10, the other side shielding portion (113) according to an embodiment of the present invention may be formed in a convex shape in the other direction of the side wall (112). In addition, the other side shielding cover (122) according to an embodiment of the present invention may be formed in a convex shape in the other direction of the side wall (112).

[0091] Specifically, the other side shielding portion (113) and the other side shielding cover (122) may be formed in a convex shape while forming a curvature (R), and the other side shielding portion (113) and the other side shielding cover (122) may be formed in a convex shape while protruding in the other direction of the side wall (112).

[0092] In this way, when the other side shielding part (113) and the other side shielding cover (122) are formed in a convex shape in the other direction of the side wall (112), the user can be more effectively pressed through the massage ball (100).

[0093] In the above description, it has been described that the other side shielding portion (113) and the other side shielding cover (122) are formed in a convex shape in the other direction of the side wall (112), but it is not limited thereto.

[0094] According to an embodiment of the present invention, only the other side shielding cover (122) may be formed in a convex shape in the other direction of the side wall (112), and the other side shielding portion (113) may be formed in a flat surface shape.

[0095] In this way, if the other side shielding cover (122) is formed in a convex shape toward the other side of the side wall (112) and the other side shielding portion (113) is formed in a flat surface shape, a space can be created between the other side shielding cover (122) and the other side shielding portion (113).

[0096] When a space is created between the other side shielding cover (122) and the other side shielding part (113), the user's massage sensation can be improved by minimizing the user's contact with the other side shielding part (113) made of an injection molded material.

[0097] In the above description, it has been described that the other side shielding portion (113) is provided on the other side of the heater cover (110), but it is not limited thereto. A massage ball equipped with a sealing structure according to an embodiment of the present invention may include a second cover (160) and a second sealing member (170).

[0098] A massage ball equipped with a sealing structure according to an embodiment of the present invention can be sealed by shielding the other side of the heater cover (110) while combining the second cover (160) and the second sealing member (170) to the other side of the heater cover (110).

[0099] Referring to Fig. 11, the second cover (160) is coupled to the other side of the heater cover (110) and covers the other side of the heater cover (110) so as to shield the other side of the internal space of the heater cover (110).

[0100] Referring to FIG. 11, the second sealing member (170) is positioned between the heater cover (110) and the second cover (160), and the second sealing member (170) can seal between the heater cover (110) and the second cover (160).

[0101] By shielding the other side of the heater cover (110) through the second cover (160) and sealing between the heater cover (110) and the second cover (160) through the second sealing member (170), it is possible to prevent leakage of the heat transfer material applied to the internal space of the heater cover (110).

[0102] The second sealing member (170) may be formed of an O-ring, and the second sealing member (170) may be formed of a rubber material to seal between the heater cover (110) and the second cover (160). However, the present invention is not limited thereto, and the second sealing member (170) may be formed of various materials as long as it can seal between the heater cover (110) and the second cover (160).
