[0029] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0030] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0031] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0032] refer to Figures 1 to 7 A preferred embodiment of the heated massage arm assembly according to this application will be described in detail below, wherein the heated massage arm assembly includes a drive arm 10, at least one massage rotating member 20 and at least one heating member 30.

[0033] Specifically, the drive arm 10 has at least one fixing hole 101. The fixing hole 101 is located at the end of the drive arm 10.

[0034] The massage rotating component 20 includes a massage element 21, a plug-in rotating element 22, a fixing element 23, and a nested rotating element 24. The massage element 21 has a nesting groove 2101 formed along its axis. The plug-in rotating element 22 includes a plug-in rotating portion 221 and a fixing portion 222. The plug-in rotating portion 221 and the fixing portion 222 are coaxial and interconnected. The fixing portion 222 remains through the fixing hole 101. The plug-in rotating element 22 also includes an arm-fitting limiting portion 223. The plug-in rotating portion 221 and the fixing portion 222 extend radially to form the arm-fitting limiting portion 223. The arm-fitting limiting portion 223 remains attached to the driving arm 10.

[0035] The fixing member 23 is disposed on the side of the drive arm 10 away from the arm-attaching limiting part 223 in such a way that it is attached to the drive arm 10 and threadedly connected to the fixing part 222, so that the insert 22 is fixed to the end of the drive arm 10 by the combined action of the arm-attaching limiting part 223 and the fixing member 23.

[0036] The nested rotating member 24 has an insertion hole 2401 along its axis. The insertion and rotating part 221 passes through the insertion hole 2401 so that the nested rotating member 24 can rotate around the insertion and rotating part 221 as an axis. The nested rotating member 24 is partially inserted into the nesting groove 2101 of the massage member 21 in a manner that maintains an interference fit with the side wall of the nesting groove 2101, so that the massage member 21 can rotate synchronously with the nested rotating member 24.

[0037] The heating component 30 includes a heating unit 31 and a power supply component 32. The heating unit 31 includes a heating element 311 and a protective heat-conducting element 312. The heating element 311 is covered by the protective heat-conducting element 312, and the heating element 311 has two conductive ends 3111. The protective heat-conducting element 312 is disposed in the nesting groove 2101 in such a way that it is held against the side wall of the nesting groove 2101, so that when the heating element 311 heats up and heats the protective heat-conducting element 312, the massage component 21 is heated by heat conduction through the contact between the protective heat-conducting element 312 and the side wall of the nesting groove 2101. The power supply component 32 is disposed at the end of the driving arm 10, and the power supply component 32 is located on the side of the driving arm 10 closer to the nesting rotating component 24. The power supply component 32 has a through hole 3201 adapted to the arm-fitting limiting part 223, and the arm-fitting limiting part 223 is held in the through hole 3201. The power supply component 32 has two power supply rails 321 corresponding to the two conductive ends 3111. The two conductive ends 3111 are configured to maintain contact with the power supply rails 321, and the two power supply rails 321 of the power supply component 32 supply power to the heating element 311 through the two conductive ends 3111, so that the heating element 311 maintains heat generation.

[0038] Understandably, with the two conductive ends 3111 in contact with the two power supply rails 321, ensuring the heating element 311 remains energized, the heating element 311 generates heat and, through the protective heat-conducting element 312, heats the massage element 21, causing its temperature to rise and maintain heating. When using the heated massage element 21 to massage a user's body, it provides heat therapy to the massaged area, promoting blood circulation and relieving muscle fatigue, thereby enhancing comfort.

[0039] Since the massage element 21 can rotate synchronously with the nested rotating element 24 around the insertion rotating part 221, when the massage element 21 massages the user's body, the massage element 21 rolls on the massaged area of ​​the user's body surface, thereby reducing the friction between the massage element 21 and the user's body and improving the comfort of the massaged area of ​​the user's body.

[0040] Furthermore, since the massage element 21 remains heated, and the massage element 21 can rotate synchronously with the nested rotating element 24 around the insertion rotating part 221, the heat from the surface of the massage element 21 in contact with the user's body is transferred to the user's body and locally cooled. Through the rotation of the massage element 21 around the insertion rotating part 221, the uncooled part of the massage element 21 continuously contacts the surface of the user's body, thereby continuously transferring heat to the massaged area of ​​the user's body to maintain the thermotherapy massage for the user.

[0041] Preferably, the thickness of the arm-mounted limiting portion 223 along the axial direction is greater than the thickness of the power supply component 32.

[0042] It is understood that when the nested rotating member 24 swings along the axial direction in such a way that the insertion rotating part 221 passes through the insertion hole 2401, since the thickness of the arm-fitting limiting part 223 along the axial direction is greater than the thickness of the power supply member 32, the nested rotating member 24 can be prevented from damaging the power supply member 32 by the blocking of the arm-fitting limiting part 223, thereby preventing damage to the power supply member 32.

[0043] Specifically, the heating element 311 is implemented by including a PTC heater and a temperature control element, so as to control the temperature of the PTC heater in real time through the temperature control element, thereby preventing the massage element 21 from overheating and scalding the user. The power supply element 32 is implemented by including a PCB board.

[0044] The protective heat-conducting component 312 is made of aluminum alloy to improve the heat conductivity of the power supply rail 321.

[0045] It should be noted that when the massage member 21 rotates synchronously with the nested rotating member 24 around the insertion rotating part 221, since the heating member 311 is covered by the protective heat-conducting member 312, and the protective heat-conducting member 312 is arranged and accommodated in the nested groove 2101 in a manner that keeps it attached to the side wall of the nested groove 2101, the heating member 311 and the protective heat-conducting member 312 will rotate synchronously with the massage member 21 around the insertion rotating part 221, so that the two conductive ends 3111 rotate around the insertion rotating part 221 respectively.

[0046] In this embodiment, the heating member 30 further includes two elastic pressing members 33 corresponding to the two conductive ends 3111. One end of each of the two elastic pressing members 33 is connected to the two conductive ends 3111. The other ends of each of the two elastic pressing members 33 are respectively held in contact with the two power supply rails 321. The two power supply rails 321 are implemented as annular tracks. The insertion and rotation part 221 is coaxial with the two power supply rails 321, so that when the two conductive ends 3111 drive the two elastic pressing members 33 to rotate about the insertion and rotation part 221 as an axis, the two elastic pressing members 33 are respectively held in contact with the two power supply rails 321.

[0047] As an example, both of the elastic pressure members 33 are implemented with elastic contacts. When the two conductive ends 3111 drive the two elastic pressure members 33 to rotate about the insertion and rotating part 221, the two elastic pressure members 33 will respectively hold against the two power supply rails 321. At this time, the two power supply rails 321 of the power supply member 32 will continue to supply power to the heating element 311 through the two elastic pressure members 33 and the two conductive ends 3111, so that the heating element 311 can maintain heat generation.

[0048] Specifically, the massage element 21 is made of rubber to prevent injury to the user's body due to excessive hardness when massaging the user's body, thereby improving the user's massage comfort. At the same time, because the massage element 21 is made of rubber, it can easily mimic the action of a human hand when massaging the user's body, thus enhancing the user's massage experience.

[0049] As an example, the fastener 23 is implemented to include a nut.

[0050] Preferably, the fixing part 222 has a missing space 22201 formed along the axial direction. Correspondingly, the inner wall of the fixing hole 101 has a protrusion adapted to the missing space 22201, so as to fill the missing space 22201 through the protrusion.

[0051] It is understood that since the protrusion can restrict the rotation of the fixing part 222 in the fixing hole 101, it can prevent the fixing part 23 from slipping and falling off due to the rotation of the fixing part 222 of the insert-rotator 22, thereby improving the stability of fixing the insert-rotator 22 as a whole to the end of the drive arm 10.

[0052] Preferably, at least one oil groove 2402 is formed on the inner wall of the insertion hole 2401 along the axial direction. The oil groove 2402 is in communication with the insertion hole 2401. The oil groove 2402 is used to be filled with lubricating oil to reduce the friction between the inner wall of the insertion hole 2401 and the insertion part 221 when the nested rotating member 24 rotates about the insertion part 221, thereby improving the smoothness of the rotation of the nested rotating member 24 about the insertion part 221.

[0053] In this embodiment, multiple oil grooves 2402 are provided, and the multiple oil grooves 2402 are evenly distributed along the extension direction and located on the circumferential inner wall of the insertion hole 2401.

[0054] Preferably, the nested rotating member 24 extends into the nested groove 2101 to form a pressing portion 241 against the protective heat-conducting member 312. The protective heat-conducting member 312 remains attached to the sidewalls and bottom wall of the nested groove 2101 to increase the contact area between the protective heat-conducting member 312 and the massage member 21, making it easier for the heat from the heating member 311 to be conducted to the massage member 21 through the protective heat-conducting member 312, thereby improving the heat conduction efficiency. The top pressing part 241 is used to keep the protective heat-conducting element 312 attached to the bottom wall of the nesting groove 2101, so as to prevent the protective heat-conducting element 312 from shaking in the nesting groove 2101 when the protective heat-conducting element 312 rotates synchronously with the massage element 21 around the insertion and rotating part 221. This keeps the protective heat-conducting element 312 attached to both the side wall and the bottom wall of the nesting groove 2101, thereby maintaining a high heat conduction efficiency and ensuring that the heat from the heating element 311 is quickly conducted to the massage element 21 through the protective heat-conducting element 312.

[0055] Preferably, the nested rotating member 24 extends radially at the end away from the massage member 21 to form a nested limiting portion 242. The nested limiting portion 242 remains attached to the end of the massage member 21 in the axial direction to limit the depth of the pressing portion 241 inserted into the nesting groove 2101, preventing damage to the protective heat-conducting member 312 and / or the heating member 311 due to excessive insertion of the pressing portion 241 into the nesting groove 2101.

[0056] In this embodiment, the nested rotating member 24 further forms a plurality of insertion portions 243. The nested rotating member 24 extends at the nested limiting portion 242 in a direction parallel to the axis to form the plurality of insertion portions 243. The plurality of insertion portions 243 are retained inserted into the massage member 21.

[0057] It is understood that when the nested rotating member 24 is partially inserted into the nested groove 2101 of the massage member 21 in a manner that maintains an interference fit with the side wall of the nested groove 2101, a plurality of the insertion portions 243 will be simultaneously inserted into the massage member 21 to prevent relative displacement between the massage member 21 and the nested rotating member 24 during the synchronous rotation of the massage member 21 with the nested rotating member 24, thereby improving the stability of the massage member 21 when it rotates synchronously with the nested rotating member 24.

[0058] Preferably, the massage rotating member 20 further includes an axial limiting ring 25. The axial limiting ring 25 is disposed at the end of the insert rotating part 221 away from the fixing part 222, and the axial limiting ring 25 is kept close to the nested rotating member 24.

[0059] The axial limiting ring 25 prevents the nested rotating member 24 from disengaging from the insert rotating part 221 along the axial direction when the nested rotating member 24 rotates about the insert rotating part 221.

[0060] In this embodiment, the end of the insert-rotating part 221 that is away from the fixing part 222 is riveted to fix the axial limiting ring 25 to the end of the insert-rotating part 221 that is away from the fixing part 222.

[0061] In another variant embodiment, the axial limiting ring 25 is threaded to the end of the insert portion 221 that is away from the fixing portion 222.

[0062] Preferably, the insertion and rotation part 221, the fixing part 222 and the wall-adhering limiting part 223 are integrally formed.

[0063] Preferably, the massage rotating component 20 further includes a stabilizing unit 26. The stabilizing unit 26 includes a stabilizing protective cover 261 and a plurality of stabilizing connecting members 262. The stabilizing protective cover 261 is located at the end of the massage component 21 away from the nested rotating component 24 along the axial direction. The plurality of stabilizing connecting members 262 pass sequentially through the nested rotating component 24, the protective heat-conducting component 312, and the massage component 21 and are threadedly connected to the stabilizing protective cover 261, so as to improve the stability of the connection between the nested rotating component 24, the protective heat-conducting component 312, and the massage component 21 through the stabilizing protective cover 261 and the plurality of stabilizing connecting members 262, thereby improving the stability when the massage component 21, the nested rotating component 24, the heating component 311, and the protective heat-conducting component 312 rotate synchronously.

[0064] As an example, several of the aforementioned stabilizing connectors 262 are implemented including screws.

[0065] The protective cover 261 prevents external forces from impacting the end of the massage member 21 away from the nested rotating member 24 along the axial direction, thus providing local protection for the massage member 21.

[0066] Preferably, the heatable massage arm assembly further includes at least one protective member 40. The protective member 40 includes a cover 41 and a retaining member 42. The cover 41 includes a protective body 411. The protective body 411 is disposed at the end of the drive arm 10, and the protective body 411 is located on the side of the drive arm 10 away from the power supply member 32. That is, the drive arm 10 is located between the protective body 411 and the power supply member 32. The protective body 411 partially extends towards the power supply member 32 to be defined as a protective side 412. The protective body 411 and the protective side 412 together form a protective space 4101. The power supply member 32 is accommodated in the protective space 4101. The protective side 412 is located at the outer periphery of the power supply member 32. The protective side 412 extends partially into the protective space 4101 to form a plurality of hook-holding limiting portions 413 opposite to the protective body 411. The fixing retainer 42 is provided on the protective cover 41 in such a way that it can hold the protective cover 41 at the end of the drive arm 10 and hold the power supply member 32 in the protective space 4101.

[0067] Since the protective side 412 is located on the outer periphery of the power supply component 32, it protects the power supply component 32 from damage caused by external impact. Because several hook-holding limiting parts 413 extend partially from the protective side 412 into the protective space 4101, and these hook-holding limiting parts 413 are positioned opposite the protective body 411, they can restrict the movement of the power supply component 32 within the protective space 4101, preventing the power supply component 32 from detaching from the protective space 4101 and ensuring protection for the power supply component 32.

[0068] As an example, the retaining element 42 is implemented by including screws.

[0069] In one embodiment, the fixing retainer 42 passes through the protective body 411 of the cover 41 along the axial direction of the fixing part 222 and is threaded to the fixing part 222, so as to fix the cover 41 as a whole to the end of the drive arm 10 by means of the fixing retainer 42.

[0070] As deformable, the retaining member 42 penetrates the protective body 411 of the cover 41 and is threaded to the drive arm 10, so as to fix the cover 41 as a whole to the end of the drive arm 10 by means of the retaining member 42.

[0071] To enable those skilled in the art to understand this application, in at least one embodiment of this application, the example is that the fixing retainer 42 passes through the protective body 411 of the cover 41 along the axial direction of the fixing part 222 and is threadedly connected to the fixing part 222.

[0072] Preferably, the protective body 411 extends partially toward the location of the drive arm 10 to form a cover positioning part 4111. The drive arm 10 has a cover positioning hole 102 corresponding to the cover positioning part 4111. The cover positioning hole 102 allows the cover positioning part 4111 to pass through.

[0073] It is understandable that, since the cover positioning part 4111 of the protective body 411 passes through the cover positioning hole 102 of the driving arm 10, and the fixing retainer 42 passes through the protective body 411 of the cover 41 along the axial direction of the fixing part 222 and is threaded to the fixing part 222, the stability of the entire cover 41 being fixed to the end of the driving arm 10 is improved under the combined action of the cover positioning part 4111 and the fixing retainer 42. Compared to relying solely on the fixing retainer 42 passing through the protective body 411 of the cover 41 along the axial direction of the fixing part 222 and being threaded to the fixing part 222, this method prevents the entire cover 41 from rotating about the fixing retainer 42, thereby preventing the power supply component 32 from impacting the protective side 412, keeping the power supply component 32 within the protective space 4101, and preventing damage to the power supply component 32.

[0074] In this embodiment, the massage rotating component 20, the heating component 30, and the protective component 40 are all implemented in pairs. Two fixing holes 101 and two protective cover positioning holes 102 are respectively provided at both ends of the driving arm 10, so that the two massage rotating components 20, the two heating components 30, and the two protective components 40 are respectively disposed at both ends of the driving arm 10, allowing the heated massage arm to simultaneously massage two parts of the user's body.

[0075] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
