Description

Technical Field

[0001] This invention relates to a massage ball, and more specifically, to a massage ball with improved heat transfer properties. Background Technology

[0002] In the past, spinal thermotherapy massage devices have been widely used to relieve acute or chronic pain in the muscles and nerve tissues of the spine caused by prolonged work in an improper posture or by habitual posture, to improve blood circulation, or to eliminate momentary muscle stiffness. These devices move along the body and apply warm stimulation to the painful area to improve blood flow.

[0003] This spinal warming massage device features a heated massage ball that can apply heat stimulation while applying pressure to the user. A PTC heater, which heats up when an electric current is applied, is located in the center of the massage ball.

[0004] However, for power connection, the PTC heater is fixed in the center of the massage ball in a non-rotating state. If configured in this way, a tiny gap that can rotate relative to the PTC heater, which is fixed in a non-rotating state, and the massage ball, which can be rotatably configured, will be formed, which will reduce the effect of warm massage.

[0005] At this point, the PTC heater can be configured to contact the massage ball so that heat is transferred between the PTC heater and the massage ball by conduction. However, if configured in this way, noise may be generated due to friction during the rotation of the massage ball, and the durability may be reduced due to wear between the two.

[0006] Therefore, there is a need to develop technologies that can solve this problem. Summary of the Invention

[0007] The technical problem to be solved The present invention is intended to solve the above-mentioned problems. The purpose of the present invention is to provide a massage ball with improved heat transfer performance that can fully transfer heat to the user and enable the massage ball to rotate smoothly, and a massage ball with improved heat transfer performance including the present invention.

[0008] The subject matter of this invention is not limited to the subject matter mentioned above, and those skilled in the art to which this invention pertains can clearly understand it from the following description.

[0009] Technical solutions to solve technical problems According to one aspect of the present invention, a massage ball with improved heat transfer performance provides a warm massage effect while applying pressure to the user. The massage ball includes: a heating element, a rotating element rotatably disposed on the outer surface of the heating element, and an outer cover rotatably disposed on the outer surface of the rotating element.

[0010] At this time, the heating element may include: a heater; and a heater cover configured to surround the heater and having a heat transfer surface on its outer surface.

[0011] At this time, the heater cover includes a first cover and a second cover, the first cover being disposed on one radial side, the second cover being disposed on the other radial side and being able to be combined with the first cover, and the heater being disposed between the first cover and the second cover.

[0012] At this time, the rotating component is configured to surround the outer surface of the heating component and may have a first sliding surface that can rotate relative to the heating component.

[0014] At this time, the rotating component may include: a body that extends axially and surrounds the outer surface of the heating component; and a rotating pin that is inserted axially into the body.

[0015] At this time, the main body has a groove into which the rotating pin is inserted, and may have an outer opening on the radially outer side of the groove so that a portion of the rotating pin is exposed radially.

[0016] At this time, the rotating pin may have an outer contact portion, which is exposed radially outward through the outer opening.

[0017] At this time, the main body has a groove into which the rotating pin is inserted, and may have an inner opening on the radially inner side of the groove so that a portion of the rotating pin is exposed radially.

[0018] At this time, the rotating pin may have an inner contact portion, which is exposed radially inward through the inner opening.

[0019] At this time, the groove may include a first groove that extends from one axial side to the other.

[0020] At this point, the groove may include a second groove that extends axially from the other side to one side.

[0021] At this time, the groove includes a first groove and a second groove. The first groove extends from one side of the axial direction to the other side, and the second groove extends from the other side of the axial direction to one side. The first groove and the second groove can be arranged alternately in the circumferential direction.

[0022] At this time, the groove includes a first groove and a second groove, the first groove extending from one side of the axial direction to the other side, and the second groove extending from the other side of the axial direction to one side, wherein the first groove and the second groove can be arranged along the axial direction.

[0023] At this time, a cover retaining member may be provided between the outer cover and the rotating member, which rotates together with the outer cover.

[0024] At this time, the cover retaining member may include: a first retainer disposed on one axial side; and a second retainer disposed on the other axial side and capable of engaging with the first retainer.

[0025] At this time, the outer cover may have a fixing portion that extends radially inward so as to be positioned between the first retainer and the second retainer.

[0026] At this time, the first retainer has a retaining rod that extends axially through the fixing part, and the second retainer may have a fixing groove that allows the retaining rod passing through the fixing part to be inserted.

[0046] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can readily implement the invention. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. For clarity, parts unrelated to the description have been omitted from the drawings, and the same reference numerals are used throughout the specification for the same or similar constituent elements.

[0047] The words and terms used in this specification and claims should not be limited to their ordinary or dictionary meanings, but should be interpreted in accordance with the principle that the inventors are able to define terms and concepts, to best describe the invention.

[0048] Therefore, the embodiments and structures shown in the accompanying drawings described in this specification are equivalent to a preferred embodiment of the present invention and do not represent all the technical ideas of the present invention. Therefore, at the time of application of the present invention, the structures may be replaced by various equivalents and modifications.

[0049] In this specification, terms such as “comprising” or “having” should be understood as the presence of the features, figures, steps, actions, constituent elements, components or combinations thereof described in the specification, and do not preclude the existence or additional possibilities of one or more other features, figures, steps, actions, components or combinations thereof.

[0050] Figure 1 A perspective view showing the assembled state of a massage ball with improved heat transfer performance according to an embodiment of the present invention. Figure 2 This is a perspective view showing a massage ball with improved heat transfer performance according to an embodiment of the present invention in a state where the outer cover has been removed. In this view, direction a represents the axial direction, direction b represents the radial direction, and direction c represents the circumferential direction.

[0051] like Figure 1 and Figure 2 As shown, the massage ball 100 with improved heat transfer performance according to an embodiment of the present invention provides a warm massage effect while pressurizing the user. The massage ball 100 also includes: a heating element 120, a rotating element 130 rotatably disposed on the outer surface of the heating element 120, and an outer cover 140 rotatably disposed on the outer surface of the rotating element 130.

[0052] That is, because it has a rotating component 130 rotatably disposed on the outer surface of the heating component 120, and an outer cover 140 rotatably disposed on the outer surface of the rotating component 130, it can not only transfer heat through the rotating component 130 in a conductive manner, thereby improving the warm massage effect, but also allow the outer cover 140 to rotate smoothly through the rotating component 130. Therefore, no noise is generated during use, and there is no problem of reduced durability due to wear.

[0053] At this time, the massage ball 100 can be fixedly connected to the first side plate 110 fixedly connected to the support arm 21. This support arm 21 is configured on the support part 20 of the heated massage device described later, and can be rotated at a certain angle during the heated massage process. The first side plate 110 is fixedly attached to the support arm 21, and the heating element 120 is fixedly attached to the first side plate 110. Therefore, during the user's application of pressure, the massage ball 100 can not only stably support the user's body, but also stably supply current to the heating element 120.

[0054] That is, with the first side plate 110 and the heating element 120 fixedly attached to the support arm 21, the rotating element 130 is rotatably disposed on the outer surface of the heating element 120, and the outer cover 140 is rotatably disposed on the outer surface of the rotating element 130.

[0055] Figure 3 A front view of a heating element according to an embodiment of the present invention is shown.

[0056] like Figure 3 As shown, the heating element 120 may include a heater 121 and a heater cover 122 configured to surround the heater 121 and having a heat transfer surface hs on its outer surface.

[0057] That is, as current is supplied to heater 121, if heater 121 heats up, the heat is transferred through heater cover 122 and then through heat transfer surface hs to rotating component 130, thereby transferring heat through this conduction method to improve the warm massage effect. At this time, heater 121 can be a PTC heater, but it is not necessarily limited to this. If it is a structure capable of generating heat, it can be a heating wire or other structures.

[0058] This heater cover 122 can be fixed to the aforementioned first side plate 110. like Figure 3 As shown, the heater cover 122 may include a first cover 122a and a second cover 122b, the first cover being disposed on one side of radial b, the second cover 122b being disposed on the other side of radial b and being able to be combined with the first cover 122a, and the heater 121 being disposed between the first cover 122a and the second cover 122b.

[0059] That is, since the first cover 122a and the second cover 122b are configured to be combinable, the heater 121 and the heater cover 122 can be easily combined, thereby improving manufacturability. In this case, the first cover 122a has a connecting protrusion protruding into the second cover 122b, and the second cover 122b may have a connecting groove into which the connecting protrusion is inserted, and the connecting protrusion and the connecting groove may be configured to be coupled in an interference fit manner. Alternatively, the second cover 122b has a connecting protrusion, the first cover 122a is configured to have a connecting groove, and the connecting protrusion and the connecting groove may be configured to be coupled in an interference fit manner.

[0060] Figure 4 A perspective view illustrating the configuration of the heating element and the rotating element according to an embodiment of the present invention. Figure 5 To illustrate a perspective view of a rotating component according to an embodiment of the present invention, Figure 6 A front view of a rotating component according to an embodiment of the present invention is shown.

[0061] like Figures 4 to 6 As shown, the rotating component 130 may have a first sliding surface ss1, which is configured to surround the outer surface of the heating component 120 and can rotate relative to the heating component 120.

[0062] That is, the rotating component 130 has a first sliding surface ss1, so that the rotating component 130 can rotate relative to the heating component 120 even if the heating component 120 is fixed. In addition, during the rotation of the rotating component 130, heat can be transferred by conduction through the first sliding surface ss1, thereby improving the warm massage effect.

[0063] like Figures 4 to 6 As shown, the rotating component 130 may have a second sliding surface ss2, which is configured to support the inner surface of the outer cover 140 and can rotate relative to the outer cover 140.

[0064] That is, the rotating component 130 has a first sliding surface SS1 on its radially inner side (b), allowing it to rotate relative to the heating component 120, and a second sliding surface SS2 on its radially outer side (b), allowing it to rotate relative to the outer cover 140. With this configuration, based on the heating component 120, not only can it rotate relative to the rotating component 130, but the outer cover 140 can also rotate relative to the rotating component 130, thus enabling smoother rotation of the outer cover 140. Furthermore, during the rotation of the outer cover 140, heat can be transferred through the second sliding surface SS2 via conduction, thereby improving the warm massage effect.

[0065] At this time, the rotating component 130 and the outer cover 140 can have the same rotational speed, but are not limited to this; the rotating component 130 and the outer cover 140 can also have different rotational speeds.

[0066] like Figure 5 and Figure 6 As shown, the rotating component 130 may include: a body 131 extending axially a and surrounding the outer surface of the heating component 120, and a rotating pin 132 inserted into the body 131 axially a.

[0067] At this time, the rotating pin 132 inserted into the main body 131 can be configured to rotate relative to the main body 131. That is, since the rotating pin 132 is configured to rotate relative to the main body 131 when inserted into the main body 131, the rotating pin 132 can also rotate freely relative to the main body 131 during the rotation of the main body 131 relative to the heating element 120, thus enabling the rotation of the main body 131 to proceed more smoothly.

[0068] The main body 131 has a first sliding surface ss1 on the inner side of the radial b, and a second sliding surface ss2 on the outer side of the radial b, but it is not necessarily limited to this. Even without the first sliding surface ss1 and the second sliding surface ss2, it can be configured to have a rotating pin 132 to allow the main body 131 to rotate smoothly.

[0069] In addition, during the rotation of the main body 131, heat can be transferred by conduction through the rotating pin 132, thereby improving the warm massage effect.

[0070] Figure 7 An enlarged front view is provided to show the grooves of a rotating component according to an embodiment of the present invention.

[0071] like Figure 7 As shown, the main body 131 has a groove 131a into which a rotating pin 132 is inserted, and an outer opening 131b may be provided on the radially b outer side of the groove 131a so that a portion of the rotating pin 132 is exposed radially b.

[0072] That is, the rotating pin 132 can be exposed from the groove 131a to the radially outward side through the outer opening 131b, and the portion exposed to the radially outward side contacts the outer cover 140, thereby transferring heat by conduction.

[0073] At this time, if the rotating pin 132 is exposed outside the groove 131a only through the outer opening 131b, it is preferable to have a first sliding surface ss1 on the radial b inner side of the main body 131. If it is configured in this way, the main body 131 can rotate smoothly relative to the heating element 120.

[0074] Figure 8 An enlarged front view showing the state in which a rotating pin is inserted into a slot in a rotating component according to an embodiment of the present invention.

[0075] like Figure 8As shown, the rotating pin 132 may have an outer contact portion 132a, which protrudes radially outward through an outer opening portion 131b.

[0076] That is, the outer contact portion 132a exposed radially outward contacts the outer cover 140, thereby transferring heat by conduction.

[0077] At this time, if only the outer contact portion 132a is exposed, it is preferable to have a first sliding surface ss1 on the radial inner side of the main body 131. If it is configured in this way, not only can the main body 131 and the heating element 120 rotate smoothly relative to each other, but the outer cover 140 can also rotate smoothly relative to the main body 131.

[0078] like Figure 7 As shown, the main body 131 has a groove 131a into which a rotating pin 132 is inserted, and an inner opening 131c may be provided on the radial b side of the groove 131a so that a portion of the rotating pin 132 is exposed radially b.

[0079] That is, the rotating pin 132 can be exposed from the groove 131a to the radially inner side through the inner opening 131c, and the part exposed to the radially inner side contacts the heating element 120, thereby transferring heat by conduction.

[0080] At this time, if the rotating pin 132 is exposed outside the groove 131a only through the inner opening 131c, it is preferable to have a second sliding surface ss2 on the radially b outer side of the main body 131. When configured in this way, the outer cover 140 can rotate smoothly relative to the main body 131.

[0081] Figure 8 An enlarged front view showing the state in which a rotating pin is inserted into a slot in a rotating component according to an embodiment of the present invention.

[0082] like Figure 8 As shown, the rotating pin 132 may have an inner contact portion 132b, which is exposed radially inward through an inner opening 131c.

[0083] That is, the outer contact portion 132a exposed radially inward makes contact with the heating element 120, thereby transferring heat by conduction.

[0084] At this point, if only the inner contact portion 132b is exposed, it is preferable to have a second sliding surface ss2 on the radially b outer side of the main body 131. If configured in this way, not only can the main body 131 and the heating element 120 rotate smoothly relative to each other, but the outer cover 140 can also rotate smoothly relative to the main body 131.

[0085] Figures 9 to 11 A perspective view is provided to illustrate a rotating component according to various embodiments of the present invention.

[0086] like Figure 9 As shown, groove 131a may include a first groove extending from one side of axial direction a to the other. In this case, an anti-disengagement surface may be provided on the other side of groove 131a along axial direction a to prevent the rotating pin 132 from disengaging. With this configuration, the operator can easily assemble the device by inserting the rotating pin 132 from one side of axial direction a to the other, thereby improving assemblability.

[0087] like Figure 10 As shown, groove 131a may include a second groove extending from one side of axial direction a to the other. In this case, an anti-disengagement surface may be provided on the axial direction a side of groove 131a to prevent the rotating pin 132 from disengaging. With this configuration, the operator can easily assemble the device by inserting the rotating pin 132 from the other side of axial direction a to the other side, thereby improving assemblability.

[0088] Figure 11 As shown, the groove 131a may include a first groove and a second groove. The first groove extends from one side of the axial direction a to the other side, and the second groove extends from the other side of the axial direction a to one side. The first groove and the second groove may be alternately arranged along the circumferential direction c. If configured in this way, the axial direction a side of the main body 131 is supported by a rotating pin 132 inserted into the first groove, and the axial direction a side of the main body 131 is supported by a rotating pin 132 inserted into the second groove, thereby enabling smooth rotation of the main body 131.

[0089] like Figure 5 As shown, the groove 131a may include a first groove and a second groove. The first groove extends from one side of axis a to the other side, and the second groove extends from the other side of axis a to one side. The first groove and the second groove can be arranged along axis a. If configured in this way, the axis a side of the main body 131 is supported by a rotating pin 132 inserted into the first groove, and the axis a side of the main body 131 is supported by a rotating pin 132 inserted into the second groove, thereby enabling smooth rotation of the main body 131.

[0090] Figure 12 A perspective view showing the massage ball with improved heat transfer performance according to another embodiment of the present invention, with the first side plate removed. Figure 13 A perspective view showing the assembled state of the outer cover and the cover retaining component according to another embodiment of the present invention.

[0091] like Figure 12 and Figure 13 As shown, a cover retaining member 150 may be provided between the outer cover 140 and the rotating member 130, which rotates together with the outer cover 140. If the cover retaining member 150 is provided in this way, the outer cover 140 can not only be stably supported during the user's pressurization process, but the outer cover 140 can also be prevented from detaching arbitrarily.

[0092] At this point, the cover retaining member 150 can be made of a material with excellent heat transfer properties so that the heat transferred through the rotating member 130 can be smoothly transferred to the outer cover 140. As an example, the cover retaining member 150 can be made of aluminum, which has excellent heat transfer properties, but it is not necessarily limited to this. Any material can be used if it can provide stable support for the outer cover 140 and has excellent heat transfer properties.

[0093] Figure 14 To illustrate a perspective view of the outer cover and cover retaining member in an exploded state according to another embodiment of the present invention, Figure 15 This is a cross-sectional view showing the assembled state of the outer cover and the cover retaining component according to another embodiment of the present invention.

[0094] like Figure 14 and Figure 15 As shown, the cover retaining member 150 may include: a first retainer 151 disposed on one side of axial direction a, and a second retainer 152 disposed on the other side of axial direction a and capable of engaging with the first retainer 151.

[0095] That is, with the outer cover 140 positioned between the first retainer 151 and the second retainer 152, the outer cover 140 and the cover retainer 150 can be assembled by engaging the first retainer 151 and the second retainer 152 in the axial direction a, thereby improving manufacturability.

[0096] like Figure 14 and Figure 15 As shown, the outer cover 140 may have a fixing portion 141 that extends radially inward to be positioned between the first retainer 151 and the second retainer 152.

[0097] That is, even if the first retainer 151 and the second retainer 152 are inserted into the radial b inner side of the outer cover 140, the outer cover 140 and the cover retainer 150 can be assembled by the fixing part 141. Therefore, not only is the structural stability improved, but also, since the first retainer 151 and the second retainer 152 are inserted into the radial b inner side of the outer cover 140, the foreign body sensation felt by the user can be minimized by the cover retainer 150 during the user pressurization process.

[0098] like Figure 14 and Figure 15 As shown, the first retainer 151 has a retaining rod 151a that extends axially a and passes through the fixing part 141, and the second retainer 152 may have a fixing groove 152a that allows the retaining rod 151a passing through the fixing part 141 to be inserted.

[0099] That is, the operator first assembles the retaining rod 151a of the first retaining member 151 to pass through the fixing part 141, and then the retaining rod 151a passing through the fixing part 141 can be inserted into the fixing groove 152a to assemble the second retaining member 152. This simplifies assembly and improves manufacturability. Furthermore, the first retaining member 151 and the second retaining member 152 can stably fix the axial position a of the outer cover 140, and during the rotation of the outer cover 140, the first retaining member 151 and the second retaining member 152 rotate together, thereby enabling the outer cover 140 to rotate stably.

[0100] Figure 16 A cross-sectional view illustrating a massage ball with improved heat transfer performance according to another embodiment of the present invention.

[0101] like Figure 16 As shown, a second side plate 160 may also be included, which is fixedly connected to the heating element 120 and is configured opposite to the first side plate 110. With the second side plate 160 in this way, it is possible to prevent the rotating element 130 and the outer cover 140 from arbitrarily disengaging in the axial direction a during the relative rotation of the rotating element 130 and the outer cover 140 with respect to the heating element 120.

[0102] At this time, the second side plate 160 can be configured to be disposed on the radially b inner side of the outer cover 140. If configured in this way, the foreign body sensation felt by the second side plate 160 can be minimized during the process of the massage ball 100 pressurizing the user.

[0103] Figure 17 This is a structural diagram illustrating a heated massage device including a massage ball with improved heat transfer performance according to an embodiment of the present invention.

[0104] like Figure 17 As shown, a warm massage device according to another embodiment of the present invention includes a massage ball 100 with improved heat transfer performance. The warm massage device includes: a conveying part 10, which moves the massage ball 100 of the user in the length direction; a support part 20, which has a support arm 21 fixedly connected to the massage ball 100; a lifting part 30, which raises or lowers the support part 20 in the height direction; and a power supply part 40, which supplies current to the massage ball 100.

[0105] This heated massage device can be inserted into a pad that supports the user's body, and while the heated massage device is inserted into the pad, it moves along its length (in the same direction as the user's spine) to apply pressure to the user's body.

[0106] This type of mat can be configured on the main body that supports the user's upper body, and an auxiliary part that supports the user's lower body can be connected to the main body. In this case, the main body can be configured to support not only the user's upper body but also the buttocks, while the auxiliary part can be configured to support only the user's legs.

[0107] At this time, the pad can also be configured on the auxiliary part that supports the user's lower body, or it can be configured such that the pad is configured on both the main body and the auxiliary part.

[0108] Individual leg components can be configured on the body portion having a pad, such that the upper surface of the pad is spaced apart from the ground, allowing the user to receive a massage in a comfortable posture.

[0109] The leg component can be manufactured in a generally rectangular strip shape. That is, it can include a side frame corresponding to the side of the main body, a lower frame supporting the ground, and a connecting frame connecting the side frame and the lower frame. The frames can be manufactured as a single piece or manufactured separately and then combined. The side frame can be made in a plate shape, and the lower frame can be made in a rod shape.

[0110] The aforementioned main body may form a guide groove, and the auxiliary part may form a guide protrusion that inserts into the guide groove, thereby enabling the auxiliary part to slide. Alternatively, a guide groove may be formed on the auxiliary part, and a guide protrusion may be formed on the main body, thereby enabling the auxiliary part to slide.
