The cover 24 is installed on the mounting part 221, and the heating element 23 is installed on the mounting part 221 and is covered by the cover 24. When the heating element 23 is in operation, it outputs heat toward the cover 24. When the cover 24 contacts the user's waist, it heats the user's waist, so that the lumbar support 21 integrates the heating effect, thereby realizing heating and massage of the user's waist and improving the user comfort of the heating component 100.

[0050] Please refer to the attached document. Figures 1-4 In this embodiment, the heating element 23 is provided with a first connecting part and a heating body. The first connecting part is connected to the heating body, and the heating body faces the cover body 24. The first connecting part is connected to the surface of the mounting part 221 so that the heating element 23 can be connected to the connecting part 22 through the cooperation of the first connecting part and the mounting part 221. The heating body is integrated into the first connecting part and outputs heat towards the cover body 24 in the working state so that the heat output by the heating body can be conducted to the user's waist through the cover body 24, thereby realizing the heating massage of the user's waist and improving the comfort of using the heating component 100.

[0051] In this embodiment, when the heating element 23 is a flexible circuit board module, the first connecting part serves as the base of the flexible circuit board module and is attached to the surface of the mounting part 221; the heating body is integrated into the first connecting part and serves as the heating part of the flexible circuit board module; to form an integrated heating structure, the heating element 23 of the flexible circuit board module is relatively thin, which facilitates the use of the narrow space between the connecting element 22 and the cover body 24, and reduces the space occupied between the connecting element 22 and the cover body 24.

[0052] Alternatively, when the heating element 23 is a heating plate, the first connecting part serves as the bottom of the heating plate and is attached to the surface of the mounting part 221; the heating body is integrated into the first connecting part and serves as the heating part of the heating plate; so that the first connecting part only undertakes the bottom support and attachment functions and does not directly participate in the circuit or signal transmission, thereby facilitating the heating body to be an independent heating layer.

[0053] Alternatively, when the heating element 23 is a heating wire, the first connecting part serves as the connecting part 22 to which the heating wire is connected and is attached to the surface of the mounting part 221; the heating body is integrated into the first connecting part and serves as the main body of the heating wire. The first connecting part is equivalent to a small adhesive pad, which is only responsible for sticking, welding and conducting heat to both ends of the heating wire; the heating body is equivalent to the heating wire itself, and the structure of the heating wire is extremely simple, the positioning is extremely accurate and the space occupied is extremely small.

[0054] Please refer to the attached document. Figures 1-4 In this embodiment, a heating element 23 is connected to the surface of the mounting part 221, and a vibrating element 25 is connected to the inner space of the mounting part 221. The vibrating element 25 and the heating element 23 are located at different positions in the mounting part 221 and are stacked along the direction of the mounting part 221 toward the cover body 24. This allows the vibrating element 25 to make full use of the inner space of the mounting part 221. The mounting part 221 integrates the heating element 23 and the vibrating element 25. Under the vibration of the vibrating element 25, the mounting part 221 drives the cover body 24 to vibrate, so as to provide heating massage and vibration massage to the user's waist. This allows the user to receive heating massage and vibration massage to the waist at the same time during use, further improving the comfort of using the heating component 100.

[0055] Please refer to the attached document. Figures 1-5 In this embodiment of the application, the lumbar support 21 is provided with a through hole 21a, and the mounting part 221 passes through the through hole 21a so that the mounting part 221 can enter the inner side of the lumbar support 21 through the space of the through hole 21a, thereby making it easier for the mounting part 221 to be located inside the lumbar support 21 and avoiding the mounting part 221 from protruding from the outer surface of the lumbar support 21.

[0056] The connector 22 is also provided with a second connecting part 222, which is integrally connected to the mounting part 221, thereby improving the connection strength between the second connecting part 222 and the mounting part 221 and ensuring the connection stability between the second connecting part 222 and the mounting part 221. The second connecting part 222 is accommodated in the receiving groove 21b of the lumbar support 21 and connected to the lumbar support 21, so that the connector 22 is connected to the lumbar support 21, so that the connector 22 can be fixed to the inner side of the lumbar support 21 through the second connecting part 222, thereby making full use of the space of the receiving groove 21b of the lumbar support 21 and reducing the space occupied between the connector 22 and the lumbar support 21.

[0057] The receiving groove 21b is located behind the through hole 21a and is connected to the through hole 21a, so that the connector 22 can enter the receiving groove 21b through the hole 21a, thereby facilitating the connection of the connector 22 to the inner wall of the receiving groove 21b; a stepped space is formed between the receiving groove 21b and the through hole 21a, so that the diameter of the through hole 21a is larger than the groove diameter of the receiving groove 21b, which improves the installation convenience of the connector 22 relative to the receiving groove 21b. At the same time, the stepped space adapts to the contour between the connector 22 and the vibrating member 25.

[0058] The second connecting part 222 is disposed on the rear side of the mounting part 221. The second connecting part 222 is located inside the receiving groove 21b and is connected to the inner sidewall of the receiving groove 21b along the annular direction. The second connecting part 222 is glued to the inner sidewall of the receiving groove 21b; or, the second connecting part 222 is hot-pressed to the inner sidewall of the receiving groove 21b; or, the second connecting part 222 is fixedly connected to the inner sidewall of the receiving groove 21b. When the second connecting part 222 is glued to the inner sidewall of the receiving groove 21b, the second connecting part 222 is connected to the inner sidewall of the receiving groove 21b by means of glue, so that the outer contour of the second connecting part 222 fits with the inner sidewall of the receiving groove 21b, ensuring the connection stability between the second connecting part 222 and the receiving groove 21b. When the second connecting part 222 is hot-pressed onto the inner wall of the receiving groove 21b, the second connecting part 222 is connected to the inner wall of the receiving groove 21b by hot pressing, so that the outer contour of the second connecting part 222 fits against the inner wall of the receiving groove 21b, ensuring the connection stability between the second connecting part 222 and the receiving groove 21b. When the second connecting part 222 is fixedly connected to the inner wall of the receiving groove 21b, the outer contour of the second connecting part 222 is interference-fitted with the inner wall of the receiving groove 21b, so that the outer contour of the second connecting part 222 fits against the inner wall of the receiving groove 21b, ensuring the connection stability between the second connecting part 222 and the receiving groove 21b.

[0059] Please refer to the attached document. Figures 1-5In this embodiment, the connector 22 is a soft rubber material, so that the vibrating element 25 can be connected to the connector 22 by a snap-fit ​​mechanism, and the connector 22 supports the vibrating element 25, ensuring the position of the vibrating element 25 relative to the connector 22. The connector 22 is also provided with a transition portion 223, which is located between the second connecting portion 222 and the mounting portion 221, and is connected to the second connecting portion 222 and the mounting portion 221, so that the mounting portion 221 can be connected to the second connecting portion 222 through the transition portion 223; the transition portion 223 extends from the second connecting portion 222 to the mounting portion 221 and is arranged in a pleated shape; when pressure is applied to the user's waist, the mounting portion 221 is subjected to the pressure of the waist and moves elastically relative to the second connecting portion 222 under the action of the transition portion 223, so that the user's waist can compress the mounting portion 221, thereby making it easier for the vibrating element 25 to adapt to the waist position of different users and avoiding the vibrating element 25 being fixed and pressing against the user's waist.

[0060] Please refer to the attached document. Figures 1-4 In this embodiment, the vibrating element 25 is detachably connected to and housed within the mounting portion 221; this facilitates the connection or disconnection of the vibrating element 25 from the mounting portion 221, improving the ease of disassembly. The mounting portion 221 is provided with a receiving groove 221a and an opening 221b, with the receiving groove 221a communicating with the opening 221b; the vibrating element 25 enters the receiving groove 221a through the opening 221b; this allows the vibrating element 25 to be fixed inside the receiving groove 221a, thereby facilitating the fixation of the vibrating element 25 to the inside of the mounting portion 221 via the receiving groove 221a, reducing the space occupied by the vibrating element 25 and the connecting member 22. When the vibrating element 25 is in the receiving groove 221a, the inner sidewall of the receiving groove 221a elastically fits against the outer sidewall of the vibrating element 25, and the mounting part 221 positions and connects the vibrating element 25; so that the mounting part 221 restricts the range of motion of the vibrating element 25, ensuring the positional accuracy of the vibrating element 25 relative to the mounting part 221, avoiding the displacement of the vibrating element 25 relative to the user's waist, and ensuring the vibration output capability of the vibrating element 25 to the user's waist.

[0061] The heating element 23 is located outside the mounting part 221 and avoids the opening 221b, so that the vibrating element 25 can be disassembled relative to the receiving groove 221a through the opening 221b, avoiding the need to remove the heating element 23 first to disassemble the vibrating element 25.

[0062] Please refer to the attached document. Figures 1-4In this embodiment, the diameter of the receiving groove 221a is larger than the diameter of the opening 221b to form an inverted structure with a larger inner diameter and a smaller outer diameter, preventing the vibrating element 25 from being directly pulled out from the opening 221b; the width of the vibrating element 25 is larger than the diameter of the opening 221b; the opening 221b is arranged in a long strip shape; the vibrating element 25 enters the opening 221b along an inclined direction and enters the receiving groove 221a through the opening 221b, so that the vibrating element 25 cannot be directly pulled out in a direction perpendicular to the opening 221b, ensuring that the vibrating element 25 is not easy to loosen or accidentally move out after installation; the vibrating element 25 is placed flat in the receiving groove 221a and is subjected to the positioning force of the mounting part 221; ensuring the positional accuracy of the vibrating element 25 and preventing the vibrating element 25 from shaking or shifting.

[0063] The portion forming the receiving groove 221a in the mounting part 221 extends from the outer surface of the mounting part 221 toward the second connecting part 222 and is located between the outer surface of the mounting part 221 and the second connecting part 222. By utilizing the structural depth to enhance the support for the vibrating member 25, reliability is improved, and reliable installation and anti-loosening of the vibrating member 25 are achieved, which combines assembly convenience and usage safety.

[0064] Please refer to the attached document. Figures 1-4 In this embodiment, the cover 24 is fitted onto the mounting portion 221 and can cover the opening 221b; the cover 24 is a metal part; so that the cover 24 can block the vibrating element 25 and the heating element 23, and further prevent the vibrating element 25 and the heating element 23 from detaching from the mounting portion 221.

[0065] The cover body 24 is provided with a mounting arm 241, which is mounted on the mounting part 221 so that the cover body 24 can be connected to the mounting part 221 through the mounting arm 241. The cover body 24 and the mounting part 221 are in a relatively static state so that the cover body 24 and the mounting part 221 can clamp the vibrating element 25 and the heating element 23. This allows the cover body 24 and the mounting part 221 to limit the different positions of the vibrating element 25 and the heating element 23 respectively, ensuring the stability and accuracy of the vibrating element 25 and the heating element 23. The cover body 24 can receive the vibration force output by the vibrating element 25 so that the vibration force output by the vibrating element 25 can be transmitted to the user's waist through the cover body 24 to achieve a massage effect on the user's waist.

[0066] In the second embodiment, a lumbar support chair includes a heating assembly 100; the lumbar support member 21 of the heating assembly 100 is detachably connected to the second support portion 12 of the heating assembly 100, so that the lumbar support member 21 of the heating assembly 100 can be connected to or detached from the second support portion 12, and the lumbar support member 21 of the heating assembly 100 is detachably connected to the second support portion 12 by an elastic band; the sidewall of the lumbar support member 21 facing the second support portion 12 is fitted to the surface of the second support portion 12, ensuring the fit between the lumbar support member 21 and the second support portion 12.

[0067] The lumbar support 21 comprises a sponge layer and a leather layer. The leather layer is located outside the sponge layer and serves as the surface layer of the sponge layer, allowing the leather layer to wrap around the sponge layer and prevent it from being lost. The leather layer has through holes, allowing the mounting part 221 to pass through and insert into the leather layer. A second connecting part 222 connects to the leather layer or a sponge layer, allowing the second connecting part 222 to connect to the lumbar support 21 via the sponge layer or the leather layer. The leather layer is harder than the sponge layer, achieving a functional layered structure of hard outside and soft inside, thus balancing protection, support, comfort, and durability. The leather layer prevents wear and tear during daily use. The relatively stiff leather layer is not easily deformed, maintaining the shape and providing a crisp appearance, preventing sagging. While the sponge is soft and comfortable, it lacks self-supporting ability and requires the leather layer for shaping and support.
