The size of the heat insulating cap 100 of one example can be smaller than the size of the bottom surface of the support shaft member 200. The heat insulating cap 100 of one example can be configured to cover only the center portion of the bottom surface of the support shaft member 200. Therefore, the heat insulating cap 100 can block the heat from being released from the center portion of the bottom surface of the support shaft member 200 to the outside, and the inner contour portion of the support shaft member 200 can be exposed to the outside. The heat insulating cap 100 of one example can be made of a rubber material or a plastic material with low thermal conductivity, but is not limited thereto as long as it is a material that can block heat release.

[0101] The support shaft member 200 can fix the heat generating member 600. The heat generating member 600 can be inserted and fixed inside the support shaft member 200. The support shaft member 200 can transfer the heat transferred from the heat generating member 600 to the buffer member 500 through the insertion member 400 externally connected to the support shaft member 200. For example, the support shaft member 200 can be made of a metal material with high thermal conductivity.

[0102] In addition, the support shaft member 200 is exposed to the outside, and can directly transmit the heat transmitted from the heat generating member 600 to the user. The user can feel the warmth from the bottom surface of the support shaft member 200. The bottom surface of the support shaft member 200 protrudes laterally more than the side surface, thereby preventing foreign matter from flowing into the inside of the massage ball 3120.

[0103] In addition, the support shaft member 200 is capable of supporting the internal components of the massage ball 3120. The support shaft member 200 can be made into an integral structure with a flange, which includes: a first surface for inserting the internal components; a second surface, which is located in the opposite direction to the first surface and has a larger area than the first surface. The first surface of the support shaft member 200 can be a bottom surface, and the second surface can be a side surface. An example of the support shaft member 200 can have a cylindrical shape in which the bottom surface protrudes more than the side surface, but is not limited to this. At least one of the washer member 300, the insertion member 400, the buffer member 500 and the bushing member 700 can be sleeved on the side surface of the support shaft member 200. The support shaft member 200 can be combined with the unit frame 3110 through the combining member 900.

[0104] The insert member 400 can maintain the shape of the buffer member 500. The insert member 400 is located inside the buffer member 500 and can maintain the shape of the buffer member 500, which can be made of a soft material. In addition, the insert member 400 is externally connected to the support shaft member 200 and inserted, so that the buffer member 500 can be combined with the support shaft member 200. In one example, the insert member 400 can be made of a metal material with high thermal conductivity.

[0105] In addition, the insert member 400 can transfer the heat generated by the heat generating member 600 to the buffer member 500. In order to effectively transfer heat to the buffer member 500, the insert member 400 of an embodiment of the present invention may have a through insertion gap and a protruding member. Figure 7 and Figure 8 In the description.

[0106] The cushioning member 500 can provide a soft massage feeling to the user. The cushioning member 500 can directly provide massage to the user at the outermost contour of the massage ball 3120. In one example, the cushioning member 500 can be made of a soft material and a material with high thermal conductivity, but is not limited thereto.

[0107] In addition, the buffer member 500 can directly transfer the heat transferred from the heat generating component 600 to the user. The user can receive a warm feeling from the buffer member 500. The buffer member 500 of one example is configured to surround the insertion member 400, and can maintain its shape through the insertion member 400. The buffer member 500 of one example can be formed integrally with the insertion member 400 by a method such as injection molding, and the buffer member 500 is configured to surround the support shaft member 200 via the insertion member 400, so as to receive the heat of the heat generating component 600 inserted into the support shaft member 200.

[0108] The heating component 600 is capable of adjusting the temperature of the massage ball 3120. Specifically, the heating component 600 is capable of raising the temperature of the massage ball 3120 to make it warm. The heating component 600 is inserted into the support shaft member 200 disposed at the inner center, thereby being able to transfer heat to the massage ball 3120 evenly. The heating component 600 transfers heat to the support shaft member 200 as a heat source, and the support shaft member 200 is inserted into the member 400, thereby being able to transfer heat to the buffer member 500. An example of the heating component 600 may be a positive temperature coefficient (PTC) heater, but is not limited thereto. On the one hand, the temperature of an example of the heating component 600 may be adjusted by a control unit, but is not limited thereto.

[0109] The spring member 650 can fix the heat generating member 600 to the support shaft member 200. The heat generating member 600 can be inserted into the insertion groove of the first member in the support shaft member 200, but due to tolerance, it may not be closely attached to the support shaft member 200. Therefore, the massage ball 3120 of the first embodiment of the present invention can make the heat generating member 600 closely attached to the inner wall surface of the support shaft member 200 by inserting the spring member 650 between the heat generating member 600 and the support shaft member 200.

[0110] The spring member 650 of one embodiment of the present invention may include: a first spring surface 651, which contacts the lower surface of the heat generating member 600; and a second spring surface 652, which extends from the first spring surface 651 and contacts the side surface of the heat generating member 600. The end of the second spring surface 652 may be bent toward the first spring surface 651 and has elasticity. When the spring member 650 and the heat generating member 600 are inserted into the insertion groove of the first member of the support shaft member 200, the end of the second spring surface 652 pushes the heat generating member 600 toward the inner wall surface of the support shaft member 200, so that it can be closely attached.

[0111] The washer member 300 can adjust the interval between the support shaft member 200 and the insertion member 400 and / or the interval between the insertion member 400 and the bushing member 700. The washer member 300 of one example may have a circular ring shape, and may be clamped on the side of the support shaft member 200 and contact the bottom surface of the insertion member 400. One surface of the washer member 300 may contact the insertion member 400, and the other surface may contact the bushing member 700.

[0112] The washer member 300 pushes the insertion member 400 toward the bottom surface of the support shaft member 200, thereby preventing a space from being generated between the support shaft member 200 and the insertion member 400. By preventing a space from being generated between the support shaft member 200 and the insertion member 400, the washer member 300 keeps a small interval between the support shaft member 200 and the insertion member 400, and enables the heat of the support shaft member 200 to be effectively transferred to the insertion member 400. In addition, the washer member 300 can fill a hollow space that may be generated between the insertion member 400 and the bushing member 700.

[0113] In addition, the washer member 300 can play a role in buffering the pressure of the user pressing the massage ball 3120. When viewed from the side, the washer member 300 of one example may have a shape protruding upward and downward. Specifically, the washer member 300 of one example may be repeatedly bent to have a wave shape, and part of it may contact the insertion member 400, and part of it may contact the bushing member 700.

[0114] When the user's body contacts the massage ball 3120, pressure is applied to the insertion member 400, so that the insertion member 400 presses the gasket member 300. Since the gasket member 300 of one example may have elasticity, the bent portion of the gasket member 300 may be deformed by the pressure, and all parts of the gasket member 300 may be unfolded to contact the insertion member 400 and the bushing member 700 at the same time. When the user's body leaves the massage ball 3120, the gasket member 300 can be restored to the original state, and the gasket member 300 repeatedly deforms and restores, thereby being able to play a buffering role.

[0115] The bushing member 700 can insulate the heat generating member 600 from other components. In addition, the bushing member 700 can block the heat generated from the heat generating member 600 from being released to the outside in an unnecessary portion. The bushing member 700 can block the internal components of the massage ball 3120 from the outside, so that the heat can be concentrated to the buffer member 500.

[0116] The bushing member 700 of one example may be composed of a hollow cylindrical shape, but is not limited thereto. The bushing member 700 of one example may be configured to surround the support shaft member 200 and prevent the heat of the support shaft member 200 from being released to the outside. In addition, the bushing member 700 can prevent foreign matter from flowing into the inside of the massage ball 3120. One side of the bushing member 700 of one example contacts the gasket member 300, and the other side contacts the unit frame 3110, and can be fixed by the coupling member 900. The bushing member 700 of one example may be composed of a rubber material or a plastic material with low thermal conductivity, but is not limited thereto as long as it is a material that can block heat release.

[0117] The cover member 750 can cover the heat generating member 600 to prevent it from detaching. In addition, the cover member 750 can block the heat generated by the heat generating member 600 from being released to the outside of the massage ball 3120. In one example, the cover member 750 can be made of a rubber material or a plastic material with low thermal conductivity, but it is not limited to this as long as it is a material that can block heat release.

[0118] The coupling member 900 can fix the massage ball 3120 to the unit frame 3110. In addition, the coupling member 900 can couple the internal components of the massage ball 3120. The coupling member 900 in one example can couple at least one of the support shaft member 200, the bushing member 700, and the cover member 750. The coupling member 900 in one example can be composed of a screw, but is not limited thereto.

[0119] Figure 7 is a cross-sectional view of a massage ball according to a first embodiment of the present invention as viewed from above, Figure 8 This is a cross-sectional view of the massage ball according to the first embodiment of the present invention as viewed from the side.

[0120] Reference Figure 7 and Figure 8 The massage ball 3120 of the first embodiment of the present invention may include at least one of a heat insulating cap 100, a support shaft member 200, a washer member 300, an insert member 400, a buffer member 500, a heat generating member 600, a spring member 650, a bushing member 700, a cover member 750, and a coupling member 900. Figure 7 and Figure 8 , the support shaft member 200 and the insertion member 400 are described in detail, and the description overlapping with the above contents is omitted.

[0121] The support shaft member 200 may be columnar, and may include a side surface 201 into which an internal component can be inserted, and a bottom surface 202 that can function as a cover.

[0122] The side surface 201 may include a first member insertion groove 201h1 into which the heat generating member 600 can be inserted and a second member insertion groove 201h2 into which the coupling member can be inserted.

[0123] The first member insertion groove 201h1 is a groove provided for inserting the heat generating member 600 into the interior of the support shaft member 200, and can be formed to be equal to or larger than the size of the support shaft member 200. When the size of the first member insertion groove 201h1 is formed to be larger than the size of the support shaft member 200 due to manufacturing tolerance, the heat generating member 600 and the spring member 650 can be inserted into the first member insertion groove 201h1 together, so that the heat generating member 600 can be closely attached to the inner wall surface of the support shaft member 200.

[0124] The spring member 650 is used to fix the heat generating member 600 in the first member insertion groove 201 h 1 , and the central portion of the spring member 650 is bent so as to be able to push the heat generating member 600 to contact the inner wall surface of the support shaft member 200 .

[0125] The insert member 400 may have a hollow columnar shape and may include a side protrusion 401. The side protrusion 401 is a portion protruding from the side of the insert member 400. The side protrusion 401 can be inserted into the inside of the buffer member 500, and can maintain the shape of the buffer member 500 and transfer heat. The side protrusion 401 of the insert member 400 may be provided with a protrusion member 401s and an insertion gap 401h.

[0126] The protrusion member 401s may be in the shape of a sawtooth in which the teeth are formed in a spiral shape, but the shape is not limited thereto. The protrusion member 401s, as a heat dissipation protrusion, can transfer the heat transferred from the heat generating member 600 and the support shaft member 200 to the buffer member 500. In one example, the protrusion member 401s is formed with a protrusion in a spiral shape, so that the contact area with the buffer member 500 can be increased, thereby effectively transferring heat to the buffer member 500.

[0127] In addition, the protrusion member 401s may have elasticity. When the user's body contacts the massage ball 3120, pressure is applied to the buffer member 500 and the protrusion member 401s, and the protrusion member 401s is deformed, and the protrusion member 401s can absorb the impact. When the user's body leaves the massage ball 3120, the protrusion member 401s can be restored to its original state. The protrusion member 401s can play a buffering role by repeatedly deforming and restoring.

[0128] The insertion gap 401h may be a through hole that passes through the side protrusion 401. The buffer member 500 may be inserted into the insertion gap 401h, and the bonding force between the buffer member 500 and the insertion member 400 may be increased. Specifically, when the buffer member 500 is injection molded onto the insertion member 400, the inside of the insertion gap 401h may be filled with the buffer member 500, thereby increasing the contact area between the buffer member 500 and the insertion member 400. By increasing the contact area between the buffer member 500 and the insertion member 400, the heat of the insertion member 400 may be effectively transferred to the buffer member 500. Such an insertion gap 401h may be provided at least one in the side protrusion 401 of the insertion member 400.

[0129] Fig. 9 is a perspective view showing how the massage unit of the second embodiment of the present invention is combined, Fig.10 This is an exploded perspective view showing an exploded state of a massage unit according to a second embodiment of the present invention.

[0130] Reference Fig. 9 and Fig.10 , the massage unit 3100 of the second embodiment of the present invention may include a massage ball 3130 combined with at least one of the unit frame 3110 and the unit frame 3110 .

[0131] The unit frame 3110 can fix the massage balls 3130 so that the massage balls 3130 can move along the body massage component. In one example, the massage balls 3130 can be fixed to one end and the other end of the unit frame 3110, respectively, and the middle part can be fixed to the body massage component, but it is not limited thereto. The shape of the unit frame 3110 can be changed according to the number of massage balls 3130 fixed to the unit frame 3110.

[0132] The massage ball 3130 can directly provide massage to the user's body. The massage ball 3130 of one embodiment of the present invention can provide a warm feeling while stimulating the user's body. Such a massage ball 3130 can be composed of multiple balls. In one example, only a part of the multiple massage balls 3130 can provide a heating function.

[0133] Reference Fig.10 The massage ball 3130 of the second embodiment of the present invention may include at least one of the support shaft member 200, the insertion member 400, the buffer member 500, the heat generating member 600, the spring member 650, the washer member 300, the bushing member 700, the outer heating member 810, and the coupling member 900. The massage ball 3130 of the second embodiment of the present invention is different from the massage ball of the first embodiment in that the heat insulating cap may be removed and the outer heating member 810 may be added instead of the cover member.

[0134] The support shaft member 200 can fix the heat generating member 600. The heat generating member 600 can be inserted and fixed inside the support shaft member 200. The support shaft member 200 can transfer the heat transferred from the heat generating member 600 to the buffer member 500 through the insertion member 400. For example, the support shaft member 200 can be made of a metal material with high thermal conductivity.

[0135] In addition, the support shaft member 200 can support the internal components of the massage ball 3130. The support shaft member 200 may have a cylindrical shape in which the bottom surface 202 protrudes from the side surface 201, but is not limited thereto. At least one of the washer member 300, the insert member 400, the buffer member 500, and the bushing member 700 may be inserted into the side surface 201 of the support shaft member 200. The support shaft member 200 may be combined with the unit frame 3110 through the combining member 900.

[0136] The support shaft member 200 may be columnar, and may include a side surface 201 into which an internal component can be inserted, and a bottom surface 202 that can function as a cover.

[0137] The side surface 201 may include a first member insertion groove 201h1 into which the heat generating member 600 can be inserted and a second member insertion groove 201h2 into which the coupling member can be inserted.

[0138] The first member insertion groove 201h1 is a groove provided for inserting the heat generating member 600 into the interior of the support shaft member 200, and can be formed to be equal to or larger than the size of the support shaft member 200. When the size of the first member insertion groove 201h1 is formed to be larger than the size of the support shaft member 200 due to manufacturing tolerance, the heat generating member 600 and the spring member 650 can be inserted into the first member insertion groove 201h1 together, so that the heat generating member 600 can be closely attached to the inner wall surface of the support shaft member 200.

[0139] The bottom surface 202 protrudes further than the side surface 201 to prevent foreign matter from flowing into the massage ball 3130. In addition, the bottom surface 202 is exposed to the outside, and the heat transferred from the heat generating member 600 can be directly transferred to the user. The user can feel the warmth from the bottom surface 202 of the support shaft member 200.

[0140] The insert member 400 can maintain the shape of the buffer member 500. The insert member 400 is located inside the buffer member 500 and can maintain the shape of the buffer member 500, which can be made of a soft material. In addition, the insert member 400 is sandwiched between the support shaft member 200, so that the buffer member 500 can be combined with the support shaft member 200. In one example, the insert member 400 can be made of a metal material with high thermal conductivity.

[0141] In addition, the insert member 400 can transfer heat generated from the heat generating member 600 to the buffer member 500. In order to effectively transfer heat to the buffer member 500, the insert member 400 according to an embodiment of the present invention may include a through insertion gap 401h and a protruding member 401s.

[0142] The insert member 400 may have a hollow columnar shape and may include a side protrusion 401. The side protrusion 401 is a portion protruding from the side of the insert member 400. The side protrusion 401 can be inserted into the inside of the buffer member 500, and can maintain the shape of the buffer member 500 and transfer heat. The side protrusion 401 of the insert member 400 may be provided with a protrusion member 401s and an insertion gap 401h.

[0143] The protrusion member 401s may be in the shape of a sawtooth in which the teeth are formed in a spiral shape, but is not limited thereto. The protrusion member 401s, as a heat dissipation protrusion, can transfer the heat transferred from the heat generating member 600 and the support shaft member 200 to the buffer member 500. The protrusion is formed in a spiral shape on the protrusion member 401s, so that the contact area with the buffer member 500 can be increased, thereby effectively transferring heat to the buffer member 500.

[0144] In addition, the protrusion member 401s may have elasticity. When the user's body contacts the massage ball 3130, pressure is applied to the buffer member 500 and the protrusion member 401s, and the protrusion member 401s is deformed, and the protrusion member 401s can absorb the impact. When the user's body leaves the massage ball 3130, the protrusion member 401s can be restored to its original state. The protrusion member 401s can play a buffering role by repeatedly deforming and restoring.

[0145] The insertion gap 401h may be a through hole that passes through the side protrusion 401. The buffer member 500 may be inserted into the insertion gap 401h, and the bonding force between the buffer member 500 and the insertion member 400 may be increased. Specifically, when the buffer member 500 is injection molded onto the insertion member 400, the inside of the insertion gap 401h may be filled with the buffer member 500, thereby increasing the contact area between the buffer member 500 and the insertion member 400. By increasing the contact area between the buffer member 500 and the insertion member 400, the heat of the insertion member 400 may be effectively transferred to the buffer member 500. Such an insertion gap 401h may be provided at least one in the side protrusion 401 of the insertion member 400.

[0146] The cushioning member 500 can provide a soft massage feeling to the user. The cushioning member 500 can directly provide massage to the user at the outermost contour of the massage ball 3130. In one example, the cushioning member 500 can be made of a soft material and a material with high thermal conductivity, but is not limited thereto.

[0147] In addition, the buffer member 500 can directly transfer the heat transferred from the heat generating member 600 to the user. The user can receive a warm feeling from the buffer member 500. The buffer member 500 of one example is configured to surround the insertion member 400, and can maintain its shape through the insertion member 400. The buffer member 500 of one example is configured to surround the support shaft member 200 with the insertion member 400 in between, so as to receive the heat of the heat generating member 600 inserted into the support shaft member 200.

[0148] The heating component 600 can adjust the temperature of the massage ball 3130. Specifically, the heating component 600 can increase the temperature of the massage ball 3130 to make it warmer. The heating component 600 is inserted into the support shaft component 200 arranged at the inner center, so that heat can be evenly transferred to the massage ball 3130. The heating component 600 transfers heat to the support shaft component 200 as a heat source, and the support shaft component 200 can transfer heat to the buffer component 500 through the insertion component 400. One example of the heating component 600 can be a positive temperature coefficient (PTC) heater, but is not limited to this. On the one hand, the temperature of the heating component 600 of one example can be adjusted by the control unit, but is not limited to this.

[0149] The spring member 650 can fix the heat generating member 600 to the support shaft member 200. The heat generating member 600 can be inserted into the first member insertion groove 201h1 in the support shaft member 200, but due to tolerance, it may not be closely attached to the support shaft member 200. Therefore, the massage ball 3130 of the second embodiment of the present invention inserts the spring member 650 between the heat generating member 600 and the support shaft member 200, so that the heat generating member 600 can be closely attached to the inner wall surface of the support shaft member 200.

[0150] The spring member 650 of one embodiment of the present invention may include: a first spring surface 651, which contacts the lower surface of the heat generating member 600; and a second spring surface 652, which extends from the first spring surface 651 and contacts the side surface of the heat generating member 600. The end of the second spring surface 652 may be bent toward the first spring surface 651 and has elasticity. When the spring member 650 and the heat generating member 600 are inserted into the first member insertion groove 201h1 of the support shaft member 200, the end of the second spring surface 652 pushes the heat generating member 600 toward the inner wall surface of the support shaft member 200, so that it can be closely attached.

[0151] The washer member 300 can adjust the interval between the support shaft member 200 and the insertion member 400 and / or the interval between the insertion member 400 and the bushing member 700. The washer member 300 of one example may have a circular ring shape, and may be clamped on the side surface 201 of the support shaft member 200 and contact the bottom surface of the insertion member 400. One surface of the washer member 300 may contact the insertion member 400, and the other surface may contact the bushing member 700.

[0152] The washer member 300 pushes the insertion member 400 toward the bottom surface 202 of the support shaft member 200, thereby preventing a space from being generated between the support shaft member 200 and the insertion member 400. The washer member 300 prevents a space from being generated between the support shaft member 200 and the insertion member 400, thereby keeping a small gap between the support shaft member 200 and the insertion member 400, and allowing the heat of the support shaft member 200 to be effectively transferred to the insertion member 400. In addition, the washer member 300 can fill the hollow space generated between the insertion member 400 and the bushing member 700.

[0153] In addition, the washer member 300 can play a role in buffering the pressure of the user pressing the massage ball 3130. When viewed from the side, the washer member 300 of one example may have a shape protruding in the up and down direction. Specifically, the washer member 300 of one example may be repeatedly bent to be wavy, and part of it may contact the insertion member 400, and part of it may contact the bushing member 700.

[0154] When the user's body contacts the massage ball 3130, pressure is applied to the insertion member 400, so that the insertion member 400 presses the gasket member 300. Since the gasket member 300 of one example may have elasticity, the bent portion of the gasket member 300 may be deformed by the pressure, and all parts of the gasket member 300 may be unfolded to contact the insertion member 400 and the bushing member 700 at the same time. When the user's body leaves the massage ball 3130, the gasket member 300 can be restored to its original state, and the gasket member 300 can play a buffering role by repeatedly deforming and restoring.

[0155] The bushing member 700 can insulate the heat generating component 600 from other components. In addition, the bushing member 700 can block the heat generated from the heat generating component 600 from being released to the outside at an unnecessary portion.

[0156] The bushing member 700 of one example may be composed of a hollow cylindrical shape, but is not limited thereto. The bushing member 700 of one example may be configured to surround the support shaft member 200 and prevent the heat of the support shaft member 200 from being released to the outside. In addition, the bushing member 700 can prevent foreign matter from flowing into the inside of the massage ball 3130. One side of the bushing member 700 of one example contacts the washer member 300, and the other side contacts the unit frame 3110, and can be fixed by the coupling member 900. The bushing member 700 of one example may be composed of a rubber material or a plastic material with low thermal conductivity, but is not limited thereto as long as it is a material that can block heat release.

[0157] The outer heating member 810 can cover the heating member 600 to prevent it from detaching. In addition, the outer heating member 810 can directly transfer the heat transferred from the heating member 600 to the user. The user can feel the warmth from the outer heating member 810. An example of the outer heating member 810 can be arranged on the back side of the unit frame 3110. An example of the outer heating member 810 can be made of a metal material with high thermal conductivity.

[0158] The coupling member 900 can fix the massage ball 3130 to the unit frame 3110. In addition, the coupling member 900 can couple the internal components of the massage ball 3130. The coupling member 900 in one example can couple at least one of the support shaft member 200, the bushing member 700, and the outer heating member 810. The coupling member 900 in one example can be composed of a screw, but is not limited thereto.

[0159] The massage ball 3130 of the second embodiment of the present invention as described above can provide the user with a warm feeling not only through the cushioning member 500, but also through the support shaft member 200 and the outer heating member 810. Since the cushioning member 500 heats up more slowly than the support shaft member 200 and the outer heating member 810 made of metal, the massage ball 3130 of the second embodiment of the present invention can provide the user with a warm feeling by using the support shaft member 200 and the outer heating member 810.

[0160] Fig.11 is a perspective view showing how the massage unit of the third embodiment of the present invention is combined, Fig.12 This is an exploded perspective view showing an exploded state of a massage unit according to a third embodiment of the present invention.

[0161] Reference Fig.11 and Fig.12 , the massage unit 3100 of the third embodiment of the present invention may include a massage ball 3140 combined with at least one of the unit frame 3110 and the unit frame 3110 .

[0162] The unit frame 3110 can fix the massage balls 3140 so that the massage balls 3140 can move along the body massage component. In one example, the massage balls 3140 can be fixed to one end and the other end of the unit frame 3110, respectively, and the middle part can be fixed to the body massage component, but it is not limited thereto. The shape of the unit frame 3110 can be changed according to the number of massage balls 3140 fixed to the unit frame 3110.

[0163] The massage ball 3140 can directly provide massage to the user's body. The massage ball 3140 of one embodiment of the present invention can provide a warm feeling while stimulating the user's body. Such a massage ball 3140 can be composed of multiple balls. In one example, only a part of the multiple massage balls 3140 can provide a heating function.

[0164] Reference Fig.12 The massage ball 3140 of the third embodiment of the present invention may include at least one of the support shaft member 200, the insertion member 400, the buffer member 500, the heat generating member 600, the spring member 650, the washer member 300, the bushing member 700, the inner heating member 820, the cover member 750, and the coupling member 900. The massage ball 3140 of the third embodiment of the present invention is different from the massage ball of the second embodiment in that the inner heating member 820 may be added instead of the outer heating member, and the cover member 750 may be added.

[0165] The support shaft member 200 can fix the heat generating member 600. The heat generating member 600 can be inserted and fixed inside the support shaft member 200. The support shaft member 200 can transfer the heat transferred from the heat generating member 600 to the buffer member 500 through the insertion member 400. For example, the support shaft member 200 can be made of a metal material with high thermal conductivity.

[0166] In addition, the support shaft member 200 can support the internal components of the massage ball 3140. The support shaft member 200 may have a cylindrical shape in which the bottom surface 202 protrudes from the side surface 201, but is not limited thereto. At least one of the washer member 300, the insert member 400, the buffer member 500, the bushing member 700, and the inner heating member 820 may be inserted into the side surface 201 of the support shaft member 200. The support shaft member 200 may be combined with the unit frame 3110 by the combining member 900.

[0167] The support shaft member 200 may be columnar, and may include a side surface 201 into which an internal component can be inserted, and a bottom surface 202 that can function as a cover.

[0168] The side surface 201 may include a first member insertion groove 201h1 into which the heat generating member 600 can be inserted and a second member insertion groove 201h2 into which the coupling member can be inserted.

[0169] The first member insertion groove 201h1 is a groove provided for inserting the heat generating member 600 into the interior of the support shaft member 200, and can be formed to be equal to or larger than the size of the support shaft member 200. When the size of the first member insertion groove 201h1 is formed to be larger than the size of the support shaft member 200 due to manufacturing tolerance, the heat generating member 600 and the spring member 650 can be inserted into the first member insertion groove 201h1 together, so that the heat generating member 600 can be closely attached to the inner wall surface of the support shaft member 200.

[0170] The bottom surface 202 protrudes further than the side surface 201 to prevent foreign matter from flowing into the massage ball 3140. In addition, the bottom surface 202 is exposed to the outside, and the heat transferred from the heat generating member 600 can be directly transferred to the user. The user can feel the warmth from the bottom surface 202 of the support shaft member 200.

[0171] The insert member 400 can maintain the shape of the buffer member 500. The insert member 400 is located inside the buffer member 500 and can maintain the shape of the buffer member 500, which can be made of a soft material. In addition, the insert member 400 is sandwiched between the support shaft member 200, so that the buffer member 500 can be combined with the support shaft member 200. In one example, the insert member 400 can be made of a metal material with high thermal conductivity.

[0172] In addition, the insert member 400 can transfer heat generated from the heat generating member 600 to the buffer member 500. In order to effectively transfer heat to the buffer member 500, the insert member 400 according to an embodiment of the present invention may include a through insertion gap 401h and a protruding member 401s.

[0173] The insert member 400 may have a hollow columnar shape and may include a side protrusion 401. The side protrusion 401 is a portion protruding from the side of the insert member 400. The side protrusion 401 can be inserted into the inside of the buffer member 500, and can maintain the shape of the buffer member 500 and transfer heat. The side protrusion 401 of the insert member 400 may be provided with a protrusion member 401s and an insertion gap 401h.

[0174] The protrusion member 401s may be in the shape of a sawtooth in which the teeth are formed in a spiral shape, but is not limited thereto. The protrusion member 401s, as a heat dissipation protrusion, can transfer the heat transferred from the heat generating member 600 and the support shaft member 200 to the buffer member 500. The protrusion is formed in a spiral shape on the protrusion member 401s, so that the contact area with the buffer member 500 can be increased, thereby effectively transferring heat to the buffer member 500.

[0175] In addition, the protrusion member 401s may have elasticity. When the user's body contacts the massage ball 3140, pressure is applied to the buffer member 500 and the protrusion member 401s, and the protrusion member 401s is deformed, and the protrusion member 401s can absorb the impact. When the user's body leaves the massage ball 3140, the protrusion member 401s can be restored to its original state. The protrusion member 401s can play a buffering role by repeatedly deforming and restoring.

[0176] The insertion gap 401h may be a through hole that passes through the side protrusion 401. The buffer member 500 may be inserted into the insertion gap 401h, and the bonding force between the buffer member 500 and the insertion member 400 may be increased. Specifically, when the buffer member 500 is injection molded onto the insertion member 400, the inside of the insertion gap 401h may be filled with the buffer member 500, thereby increasing the contact area between the buffer member 500 and the insertion member 400. By increasing the contact area between the buffer member 500 and the insertion member 400, the heat of the insertion member 400 may be effectively transferred to the buffer member 500. Such an insertion gap 401h may be provided at least one in the side protrusion 401 of the insertion member 400.

[0177] The cushioning member 500 can provide a soft massage feeling to the user. The cushioning member 500 can directly provide massage to the user at the outermost contour of the massage ball 3130. In one example, the cushioning member 500 can be made of a soft material and a material with high thermal conductivity, but is not limited thereto.

[0178] In addition, the buffer member 500 can directly transfer the heat transferred from the heat generating member 600 to the user. The user can receive a warm feeling from the buffer member 500. The buffer member 500 of one example is configured to surround the insertion member 400, and can maintain its shape through the insertion member 400. The buffer member 500 of one example is configured to surround the support shaft member 200 with the insertion member 400 in between, so as to receive the heat of the heat generating member 600 inserted into the support shaft member 200.

[0179] The heating component 600 can adjust the temperature of the massage ball 3140. Specifically, the heating component 600 can increase the temperature of the massage ball 3140 to warm it. The heating component 600 is inserted into the support shaft component 200 arranged at the inner center, so that heat can be evenly transferred to the massage ball 3140. The heating component 600 transfers heat to the support shaft component 200 as a heat source, and the support shaft component 200 can transfer heat to the buffer component 500 through the insertion component 400. One example of the heating component 600 can be a positive temperature coefficient (PTC) heater, but is not limited to this. On the one hand, the temperature of the heating component 600 of one example can be adjusted by the control unit, but is not limited to this.

[0180] The spring member 650 can fix the heat generating member 600 to the support shaft member 200. The heat generating member 600 can be inserted into the first member insertion groove 201h1 in the support shaft member 200, but due to tolerance, it may not be closely attached to the support shaft member 200. Therefore, the massage ball 3140 of the third embodiment of the present invention inserts the spring member 650 between the heat generating member 600 and the support shaft member 200, so that the heat generating member 600 can be closely attached to the inner wall surface of the support shaft member 200.

[0181] The spring member 650 of one embodiment of the present invention may include: a first spring surface 651, which contacts the lower surface of the heat generating member 600; and a second spring surface 652, which extends from the first spring surface 651 and contacts the side surface of the heat generating member 600. The end of the second spring surface 652 may be bent toward the first spring surface 651 and has elasticity. When the spring member 650 and the heat generating member 600 are inserted into the first member insertion groove 201h1 of the support shaft member 200, the end of the second spring surface 652 pushes the heat generating member 600 toward the inner wall surface of the support shaft member 200, so that it can be closely attached.

[0182] The washer member 300 can adjust the interval between the support shaft member 200 and the insertion member 400 and / or the interval between the insertion member 400 and the bushing member 700. The washer member 300 of one example may have a circular ring shape, and may be clamped on the side surface 201 of the support shaft member 200 and contact the bottom surface of the insertion member 400. One surface of the washer member 300 may contact the insertion member 400, and the other surface may contact the bushing member 700.

[0183] The washer member 300 pushes the insertion member 400 toward the bottom surface 202 of the support shaft member 200, thereby preventing a space from being generated between the support shaft member 200 and the insertion member 400. By preventing a space from being generated between the support shaft member 200 and the insertion member 400, the washer member 300 keeps a small interval between the support shaft member 200 and the insertion member 400, and effectively transfers the heat of the support shaft member 200 to the insertion member 400. In addition, the washer member 300 can fill the hollow space generated between the insertion member 400 and the bushing member 700.

[0184] In addition, the washer member 300 can play a role in buffering the pressure of the user pressing the massage ball 3140. When viewed from the side, the washer member 300 of one example may have a shape protruding in the up and down direction. Specifically, the washer member 300 of one example may be repeatedly bent to be wavy, and part of it may contact the insertion member 400, and part of it may contact the bushing member 700.

[0185] When the user's body contacts the massage ball 3140, pressure is applied to the insertion member 400, so that the insertion member 400 presses the gasket member 300. Since the gasket member 300 of one example may have elasticity, the bent portion of the gasket member 300 may be deformed by the pressure, and all parts of the gasket member 300 may be unfolded to contact the insertion member 400 and the bushing member 700 at the same time. When the user's body is separated from the massage ball 3140, the gasket member 300 can be restored to its original state, and the gasket member 300 can play a buffering role by repeatedly deforming and restoring.

[0186] The bushing member 700 can insulate the heat generating component 600 from other components. In addition, the bushing member 700 can block the heat generated from the heat generating component 600 from being released to the outside at an unnecessary portion.

[0187] The bushing member 700 of one example may be composed of a hollow cylindrical shape, but is not limited thereto. The bushing member 700 of one example may be configured to surround the support shaft member 200 and prevent the heat of the support shaft member 200 from being released to the outside. In addition, the bushing member 700 can prevent foreign matter from flowing into the inside of the massage ball 3130. One side of the bushing member 700 of one example contacts the washer member 300, and the other side contacts the inner heating member 820, and can be fixed by the coupling member 900. The bushing member 700 of one example may be composed of a rubber material or a plastic material with low thermal conductivity, but is not limited thereto as long as it is a material that can block heat release.

[0188] The inner heating member 820 can directly transfer the heat transferred from the heating member 600 to the user. The user can feel the warmth from the inner heating member 820. The inner heating member 820 of one example can be arranged on the front surface of the unit frame 3110. The inner heating member 820 of one example can be made of a metal material with high thermal conductivity.

[0189] The cover member 750 can cover the heat generating member 600 to prevent it from detaching. In addition, the cover member 750 can block the heat generated by the heat generating member 600 from being released to the outside of the massage ball 3140. In one example, the cover member 750 can be made of a rubber material or a plastic material with low thermal conductivity, but it is not limited to this as long as it is a material that can block heat release.

[0190] The coupling member 900 can fix the massage ball 3140 to the unit frame 3110. In addition, the coupling member 900 can couple the internal components of the massage ball 3140. The coupling member 900 in one example can couple at least one of the support shaft member 200, the bushing member 700, the inner heating 820, and the cover member 750. The coupling member 900 in one example can be composed of a screw, but is not limited thereto.

[0191] The massage ball 3140 of the third embodiment of the present invention as described above can provide the user with a warm feeling not only through the cushioning member 500, but also through the support shaft member 200 and the inner heating member 820. Since the cushioning member 500 heats up more slowly than the support shaft member 200 and the inner heating member 820 made of metal, the massage ball 3140 of the third embodiment of the present invention can provide the user with a warm feeling by using the support shaft member 200 and the inner heating member 820.

[0192] The massage ball 3140 of the third embodiment of the present invention includes an inner heating member 820, so that heat can be transferred to the user more effectively than the massage ball of the second embodiment including an outer heating member. Specifically, the inner heating member 820 can be closer to the heat generating member 600 than the outer heating member arranged on the back of the unit frame 3110, so that heat can be transferred more effectively.

[0193] Fig.13 It is a diagram showing an insertion member according to another embodiment of the present invention.

[0194] Specifically, Fig.13 (a) is a perspective view of an insertion member 400 according to another embodiment. Fig.13 (b) is a cross-sectional view showing a state where an insert member 400 and a buffer member 500 according to another embodiment are combined.

[0195] Reference Fig.13 , an insert member 400 according to another embodiment of the present invention may include at least one of an inner contour protrusion 402 , an insertion groove 403 , and an outer contour protrusion 404 .

[0196] The inner profile protrusion 402 is a protrusion that can surround the support shaft member for inserting the insertion member 400. The inner profile protrusion 402 can surround the hole that passes through the insertion member 400. Such an inner profile protrusion 402 may include at least one or more inner profile protrusions 402s. In one example, the inner profile protrusion 402s may protrude from the inner profile protrusion 402 toward the insertion groove portion 403, but is not limited thereto. The inner profile protrusion 402s can increase the contact area between the insertion member 400 and the buffer member 500, thereby increasing the bonding force and enabling rapid heat transfer.

[0197] The insertion groove 403 is a groove provided to allow the buffer member 500 to be inserted into the inner side of the insertion member 400. The insertion groove 403 may be recessed between the inner contour protrusion 402 and the outer contour protrusion 404. The buffer member 500 may be provided to fill the insertion groove 403.

[0198] The insertion groove 403 may be provided with at least one insertion hole 403h1 and / or insertion gap 403h2. The insertion hole 403h1 is a hole configured to allow the buffer member 500 to be inserted into the insertion member 400. The insertion hole 403h1 can penetrate the insertion groove 403. The buffer member 500 may be configured to fill the inside of the insertion hole 403h1. The insertion hole 403h1 increases the contact area between the insertion member 400 and the buffer member 500, thereby increasing the bonding force and enabling rapid heat transfer.

[0199] The insertion gap 403h2 may be a fine through hole that passes through the insertion groove portion 403. The buffer member 500 may be inserted into the insertion gap 403h2, and the bonding force between the buffer member 500 and the insertion member 400 may be increased. Specifically, when the buffer member 500 is injection molded onto the insertion member 400, the buffer member 500 may be filled inside the insertion gap 403h2, thereby increasing the contact area between the buffer member 500 and the insertion member 400. By increasing the contact area between the buffer member 500 and the insertion member 400, the heat of the insertion member 400 may be effectively transferred to the buffer member 500. The insertion groove portion 403 may have at least one such insertion gap 403h2.

[0200] The outer contour protrusion 404 functions as a stopper to prevent the buffer member 500 inserted into the insertion groove 403 from falling off. The outer contour protrusion 404 may be surrounded by the buffer member 500, but is not limited thereto.

[0201] As described above, the insertion member 400 according to another embodiment of the present invention can be applied to the massage ball 3120 according to the first embodiment, the massage ball 3130 according to the second embodiment, and the massage ball 3140 according to the third embodiment.

[0202] Fig.14 It is a diagram for explaining a method of controlling the temperature of a massage ball according to another embodiment of the present invention.

[0203] According to an embodiment of the present invention, a temperature sensing sensor unit 822 may be provided at the outer heating member 810 or the inner heating member 820. The temperature sensing sensor unit 822 may sense the temperature of the heating members 810 and 820 and transmit the sensed temperature information to the control unit 2000.

[0204] The control part 2000 may control the current supplied to the heat generating member 600 based on the received temperature information. For example, the control part 2000 may block the current supplied to the heat generating member 600 when the temperature information obtained from the temperature sensing sensor part 822 exceeds a predetermined threshold.

[0205] According to an embodiment of the present invention, the outer heating member 810 or the inner heating member 820 may include a physical current blocking portion 824 that physically blocks the current supplied to the heating member 600 according to the temperature of the outer heating member 810 or the inner heating member 820. In this case, the physical current blocking portion 824 may be implemented as a bimetallic module. The bimetallic module is a module that reacts differently between two metals according to heat and can be used as a circuit breaker.

[0206] For example, the current supplied to the heating component 600 can be supplied to the heating component 600 after passing through the physical current blocking portion 824, and when the temperature of the outer heating component 810 or the inner heating component 820 is higher than a predetermined threshold, the physical current blocking portion 824 physically blocks the current supplied to the heating component 600, thereby preventing an accident in which the temperature of the massage ball becomes abnormally high.

[0207] According to an embodiment of the present invention, the massage device 1000 includes both a temperature sensing sensor unit 822 and a physical current blocking unit 824, so that the temperature of the massage ball can be prevented from rising abnormally. For example, the control unit 2000 uses the temperature information obtained from the temperature sensing sensor unit 822 to control the heating component 600 once so that the temperature of the massage ball does not rise abnormally. In this case, there is a risk that the temperature of the heating component 600 becomes abnormally high due to the abnormal operation of the control unit 2000, and the physical current blocking unit 824 can physically block the current supplied to the heating component 600, so that even if the control unit 2000 fails, the temperature of the massage ball will not rise abnormally.

[0208] To this end, the threshold used by the control section 2000 may be lower than the threshold applied to the physical current blocking section 824 .

[0209] Fig.15 This is a diagram for explaining an embodiment of the present invention in which a temperature sensing sensor unit 822 and a physical current blocking unit 824 are provided on an inner heating member 820 .

[0210] According to an embodiment of the present invention, a plurality of grooves may be provided in the inner heating member 820 , and a temperature sensing sensor part 822 and a physical current blocking part 824 may be provided in each groove.
