[0057] In this embodiment, the lamp bead part 42 is provided with a corresponding lens. The lens is located inside the first light emission hole 31b and does not extend beyond the first light emission hole 31b, so that the lens is in a non-contact state with the user's waist, avoiding hard contact between the lens and the user's waist. At the same time, the light output by the lamp bead part 42 is transmitted to the user's waist through the lens, ensuring that the light output by the lamp bead part 42 is focused or dispersed on the user's waist by the lens.

[0058] Circuit board 41 is a first flexible circuit board, which is detachably connected to the inner wall of the first receiving groove 31a; this allows the first flexible circuit board to be connected to or detached from the first receiving groove 31a, improving the ease of replacement of the first flexible circuit board. The first flexible circuit board has the effect of being soft and deformable.

[0059] The circuit board 41 is provided with a first through hole 41a, which is used for the vibration module 30 to pass through. The vibration module 30 is used to massage the user's waist, so that the circuit board 41 can avoid the vibration module 30 through the space of the first through hole 41a, thereby facilitating the vibration module 30 to pass through the first through hole 41a and extend to the outer surface of the waist support 31. The vibration module 30 is a vibration massage module, a heating module or an EMS massage module, so as to realize vibration massage, heating massage or EMS massage for the user's waist.

[0060] In this embodiment of the application, the multi-ring LED combination distributes multiple LED bead sections 42. The multiple LED bead sections 42 are arranged in a dense manner, so that the multiple LED bead sections 42 work together to act on the user's waist in the working state and output sufficient heat, making full use of the photothermal effect and ensuring the heating effect of the user's waist during use. In this embodiment, when the LED module 40 is distributed left and right along the vibration module 30, and when the multiple LED parts 42 are arranged in the vertical direction, the multiple LED parts 42 form multiple sets of LED combinations, and the multiple sets of LED combinations are arranged sequentially; so that the multiple sets of LED combinations can extend along the direction of the user's spine.

[0061] Multiple LED beads 42 generate corresponding heat when emitting light, and this heat acts on the user's waist to heat and massage the user's waist, so that the user's waist can achieve a heating and massage effect during use; the multiple LED beads 42 surround each other to form a heating area, which is arranged in a rectangular or trapezoidal shape along the vertical direction, so as to heat and massage the user's waist in the vertical direction.

[0062] In this embodiment, there are multiple vibration modules 30, all of which are connected to the lumbar support 31 and are arranged on both sides of the LED module 40, so that the multiple vibration modules 30 can respectively provide a vibration massage effect on the two outer sides of the user's spine. Optionally, there are two vibration modules 30.

[0063] Please refer to the attached document. Figures 1-8 In this embodiment, the lumbar support 31 is provided with a first through hole 31c, and the mounting part 321 passes through the first through hole 31c; so that the mounting part 321 can enter the inner side of the lumbar support 31 through the space of the first through hole 31c, thereby making it easier for the mounting part 321 to be located inside the lumbar support 31 and avoiding the mounting part 321 from protruding from the outer surface of the lumbar support 31. The connector 32 is also provided with a connecting part 322, which is integrally connected to the mounting part 321, thereby improving the connection strength between the connecting part 322 and the mounting part 321 and ensuring the connection stability between the connecting part 322 and the mounting part 321. The connecting part 322 is accommodated in the second receiving groove 31d of the lumbar support 31 and is connected to the lumbar support 31, so that the connector 32 is connected to the lumbar support 31, so that the connector 32 can be fixed to the inner side of the lumbar support 31 through the connecting part 322, thereby making full use of the space of the second receiving groove 31d of the lumbar support 31 and reducing the space occupied between the connector 32 and the lumbar support 31.

[0064] In this embodiment, the second receiving groove 31d is located behind the first through hole 31c and communicates with the first through hole 31c, so that the connector 32 can enter the second receiving groove 31d through the first through hole 31c, thereby facilitating the connection of the connector 32 to the inner wall of the second receiving groove 31d. A stepped space is formed between the second receiving groove 31d and the first through hole 31c, so that the diameter of the first through hole 31c is larger than the groove diameter of the second receiving groove 31d, improving the installation convenience of the connector 32 relative to the second receiving groove 31d. At the same time, the stepped space adapts to the contour between the connector 32 and the vibrating member 33.

[0065] The connecting portion 322 is disposed on the rear side of the mounting portion 321. The connecting portion 322 is located within the second receiving groove 31d and is connected to the inner sidewall of the second receiving groove 31d along the annular direction. The connecting portion 322 is glued to the inner sidewall of the second receiving groove 31d; or, the connecting portion 322 is hot-pressed to the inner sidewall of the second receiving groove 31d; or, the connecting portion 322 is fixedly connected to the inner sidewall of the second receiving groove 31d. When the connecting portion 322 is glued to the inner sidewall of the second receiving groove 31d, the connecting portion 322 is connected to the inner sidewall of the second receiving groove 31d by means of glue, so that the outer contour of the connecting portion 322 fits the inner sidewall of the second receiving groove 31d, ensuring the connection stability between the connecting portion 322 and the second receiving groove 31d. When the connecting part 322 is hot-pressed onto the inner wall of the second receiving groove 31d, the connecting part 322 is connected to the inner wall of the second receiving groove 31d through hot pressing, so that the outer contour of the connecting part 322 fits against the inner wall of the second receiving groove 31d, ensuring the connection stability between the connecting part 322 and the second receiving groove 31d. When the connecting part 322 is fixedly connected to the inner wall of the second receiving groove 31d, the outer contour of the connecting part 322 is interference-fitted with the inner wall of the second receiving groove 31d, so that the outer contour of the connecting part 322 fits against the inner wall of the second receiving groove 31d, ensuring the connection stability between the connecting part 322 and the second receiving groove 31d.

[0066] In this embodiment, the connector 32 is a soft rubber body, so that the vibrating element 33 can be connected to the connector 32 by snapping, and the connector 32 supports the vibrating element 33; thus ensuring the position of the vibrating element 33 relative to the waist support 31.

[0067] The connector 32 is also provided with a transition portion 323, which is located between the connector 322 and the mounting portion 321 and connects the connector 322 and the mounting portion 321, so that the mounting portion 321 can be connected to the connector 322 through the transition portion 323; the transition portion 323 extends from the connector 322 to the mounting portion 321 and is arranged in a pleated shape; when pressure is applied to the user's waist, the mounting portion 321 is subjected to the pressure of the user's waist and moves elastically relative to the connector 322 under the action of the transition portion 323, so that the user's waist can compress the mounting portion 321, thereby making it easier for the vibrator 33 to adapt to the waist position of different users and avoiding the vibrator 33 being fixed and pressing against the user's waist.

[0068] In this embodiment, the mounting part 321 is provided with a receiving groove 321a and an opening 321b, with the receiving groove 321a communicating with the opening 321b. The vibrating member 33 enters the receiving groove 321a through the opening 321b, so that the vibrating member 33 can be fixed inside the receiving groove 321a. This facilitates the fixation of the vibrating member 33 to the inside of the mounting part 321 through the receiving groove 321a, reducing the space occupied by the vibrating member 33 and the connecting member 32. When the vibrating member 33 is in the receiving groove 321a, the inner wall of the receiving groove 321a elastically fits against the outer wall of the vibrating member 33. The mounting part 321 positions and connects the vibrating member 33, so that the mounting part 321 restricts the range of motion of the vibrating member 33, ensuring the positional accuracy of the vibrating member 33 relative to the mounting part 321, avoiding the displacement of the vibrating member 33 relative to the user's waist, and ensuring the vibration output capability of the vibrating member 33 to the user's waist.

[0069] In this embodiment, the diameter of the receiving groove 321a is larger than the diameter of the opening 321b; the width of the vibrating element 33 is larger than the diameter of the opening 321b; the opening 321b is arranged in a long strip shape; the vibrating element 33 enters the opening 321b along an inclined direction and enters the receiving groove 321a through the opening 321b, so that the vibrating element 33 cannot be directly pulled out in a direction perpendicular to the opening 321b, ensuring that the vibrating element 33 is not easy to loosen or accidentally move out after installation. The vibrating element 33 is placed flat in the receiving groove 321a and is subjected to the positioning force of the mounting part 321; the positional accuracy of the vibrating element 33 is guaranteed, and the vibrating element 33 is prevented from shaking or shifting. The portion forming the receiving groove 321a in the mounting part 321 extends from the outer surface of the mounting part 321 toward the connecting part 322 and is located between the outer surface of the mounting part 321 and the connecting part 322. By utilizing the structural depth, the support for the vibrating member 33 is enhanced, improving reliability and achieving reliable installation and anti-loosening of the vibrating member 33, while also providing both ease of assembly and safety of use.

[0070] In this embodiment, the vibration module 30 further includes a metal housing 34, which is fitted onto the mounting portion 321 and can cover the opening 321b. The metal housing 34 is a metal component, so that the metal housing 34 can block the vibrating element 33 and further prevent the vibrating element 33 from detaching from the mounting portion 321.

[0071] The metal housing 34 is provided with a mounting arm 341, which is mounted on the mounting part 321 so that the metal housing 34 can be connected to the mounting part 321 through the mounting arm 341. The metal housing 34 and the mounting part 321 are in a relatively static state so that the vibrating element 33 can be clamped between the metal housing 34 and the mounting part 321. This allows the metal housing 34 and the mounting part 321 to restrict different positions of the vibrating element 33, ensuring the stability and accuracy of the vibrating element 33. The metal housing 34 can receive the vibration force output by the vibrating element 33 so that the vibration force output by the vibrating element 33 can be transmitted to the user's waist through the metal housing 34 to achieve a vibration massage effect on the user's waist.

[0072] Please refer to the attached document. Figures 1-8 In this embodiment of the application, the lumbar support chair also includes a heating element 50; a metal housing 34 is installed on the mounting part 321, and the heating element 50 is installed on the mounting part 321 and covered by the metal housing 34; the heating element 50 outputs heat toward the metal housing 34 in the working state, and the metal housing 34 heats the user's waist when it comes into contact with the user's waist, so as to achieve a heating effect through the heating element 50, thereby facilitating the heating and massage of the user's waist.

[0073] In this embodiment, the heating element 50 is provided with a second connecting part 51 and a heating body 52. ​​The second connecting part 51 is connected to the heating body 52, and the heating body 52 faces the metal housing 34. The second connecting part 51 is connected to the surface of the mounting part 321 so that the heating element 50 can be connected to the connecting part 32 through the cooperation of the second connecting part 51 and the mounting part 321. The heating body 52 is integrated into the second connecting part 51 and outputs heat towards the metal housing 34 in the working state so that the heat output by the heating body 52 can be conducted to the user's waist through the sealed metal housing 34, thereby realizing the heating and massage of the user's waist.

[0074] In this embodiment, when the heating element 50 is a flexible circuit board module, the second connecting part 51 serves as the base of the flexible circuit board module and is attached to the surface of the mounting part 321; the heating body 52 is integrated into the second connecting part 51 and serves as the heating part of the flexible circuit board module; to form an integrated heating structure, the heating element 50 of the flexible circuit board module is relatively thin, which facilitates the use of the narrow space between the connecting part 32 and the encapsulated metal housing 34, and reduces the space occupied between the connecting part 32 and the encapsulated metal housing 34.

[0075] Alternatively, when the heating element 50 is a heating plate, the second connecting part 51 serves as the bottom of the heating plate and is attached to the surface of the mounting part 321; the heating body 52 is integrated into the second connecting part 51 and serves as the heating part of the heating plate; so that the second connecting part 51 only undertakes the functions of bottom support and attachment, and does not directly participate in circuit or signal transmission, thereby facilitating the heating body 52 to be an independent heating layer.

[0076] Alternatively, when the heating element 50 is a heating wire, the second connecting part 51 serves as a connector to which the heating wire is connected and is attached to the surface of the mounting part 321; the heating body 52 is integrated into the second connecting part 51 and serves as the main body of the heating wire. The second connecting part 51 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 52 is equivalent to the heating wire itself. The structure of the heating wire is extremely simple, the positioning is extremely accurate and the space occupied is extremely small.

[0077] In this embodiment, a heating element 50 is connected to the surface of the mounting part 321, and a vibrating element 33 is connected to the inner space of the mounting part 321. The vibrating element 33 and the heating element 50 are located at different positions in the mounting part 321 and are stacked along the direction of the mounting part 321 toward the metal housing 34, so that the vibrating element 33 can make full use of the inner space of the mounting part 321.

[0078] The mounting section 321 integrates a heating element 50 and a vibrating element 33. Under the vibration of the vibrating element 33, the mounting section 321 drives the metal housing 34 to vibrate, so as to provide heating and vibration massage to the user's waist, so that the user can receive heating and vibration massage to the waist at the same time during use.

[0079] The lumbar support 31 is detachably connected to the second support 12 so that the lumbar support 31 can be connected to or detached from the second support 12. The lumbar support 31 is detachably connected to the second support 12 by an elastic band. The side wall of the lumbar support 31 facing the second support 12 is in contact with the surface of the second support 12, thus ensuring the fit between the lumbar support 31 and the second support 12.

[0080] The lumbar support 31 comprises a sponge layer 311 and a leather layer 312. The leather layer 312 is located outside the sponge layer 311 and serves as the surface layer of the sponge layer 311, allowing the leather layer 312 to wrap around the sponge layer 311 and prevent the sponge layer 311 from being lost. The leather layer 312 is harder than the sponge layer 311, achieving a functional layering of a hard outer layer and a soft inner layer, thus balancing protection, support, comfort, and durability. The leather layer 312 prevents wear and tear during daily use. The relatively stiff leather layer 312 is not easily deformed, maintaining the shape and contour of the lumbar support 31, providing a crisp appearance and preventing sagging. While the sponge is soft and comfortable, it lacks the ability to maintain its shape and requires the support and shaping of the leather layer 312.

[0081] The rear side wall of the second support part 12 is connected to a control module 121, which is equipped with a third flexible circuit board. The vibrating element 33 is connected to a conductive element, which passes through the second support part 12 and is electrically connected to the third flexible circuit board. This allows the vibrating module 30, the LED module 40, and the heating element 50 to conduct electricity with the third flexible circuit board through the conductive element. This facilitates the circuit board to output signals to the vibrating module 30, the LED module 40, and the heating element 50, so that the control module 121 can control the vibrating module 30, the LED module 40, and the heating element 50 to turn on or off.

[0082] The lumbar support 31 also has a connecting layer 313, which is located between the sponge layer 211 and the second support portion 12, and closes the first opening of the first receiving groove 31a facing the second support portion 12, preventing the circuit board 41 from being exposed to the outside; the sponge layer 211 is connected to the second support portion 12 through the connecting layer 313; the connecting layer 313 is detachably connected to the second support portion 12, so that the connecting layer 313 can be connected to or detached from the second support portion 12, thereby facilitating the detachable connection of the lumbar support 31 to the second support portion 12 through the connecting layer 313, improving the ease of installation and removal of the lumbar support 31, and making it convenient to remove the lumbar support 31 for maintenance or replacement. Optionally, the connecting layer 313 can be an adhesive layer, Velcro, or a magnet. Please refer to the attached document.

The second support part 12 is connected to the first support part 11 and extends upward in a fluid manner so that the second support part 12 and the first support part 11 form an L-shape. The first support part 11 and the second support part 12 are respectively arranged relative to the user's buttocks and waist, so that the contours of the second support part 12 and the first support part 11 can be adapted to the contours of the user's buttocks and waist when in a sitting position.

[0083] The seat cushion module 20 is arranged relative to the first support part 11; the seat cushion module 20 is connected to the first support part 11; the seat cushion module 20 includes a sponge 21 and a fabric 22; the sponge 21 is covered by the fabric 22 and flexibly supports the user's buttocks; so that the user's buttocks can make flexible contact with the first support part 11 through the seat cushion module 20, thereby improving the comfort of the user's buttocks.

[0084] The vibration module 30 includes a lumbar support 31, a connector 32, a vibrator 33, and a metal housing 34. The lumbar support 31 is connected to the second support portion 12 and is used for flexible contact with the user's waist, so that the user's waist can make flexible contact with the second support portion 12 through the lumbar support 31, thereby improving the user's lumbar comfort. The connector 32 is connected to the lumbar support 31 and has a mounting portion 321, which can be arranged relative to the user's waist. The vibrator 33 is detachably connected to the mounting portion 321, so that the vibrator 33 can be connected to or detached from the mounting portion 321, thereby facilitating the detachable connection of the vibrator 33 to the connector 32 through the mounting portion 321. The vibrating element 33 is housed within the mounting portion 321 so that the vibrating element 33 can make full use of the internal space of the mounting portion 321, thereby reducing the space occupied between the vibrating element 33 and the connecting member 32. When the vibrating element 33 is in operation, it outputs a vibration force and sends the vibration force to the mounting portion 321 to provide a vibration massage to the user's waist. Thus, the waist support 31 integrates the vibrating element 33 to achieve a vibration massage effect. The waist support 31 is provided with a first receiving groove 31a and multiple first light-emitting holes 31b. The multiple first light-emitting holes 31b are connected to the first receiving groove 31a along the thickness direction of the waist support 31.

The second flexible circuit board 60 integrates a first electrical connection part 61, which is in contact with the metal housing 34, so that the metal housing 34 can perform EMS massage on the user's waist under the power of the first electrical connection part 61. This allows the lumbar support component 31 to integrate the EMS massage effect, thereby realizing EMS massage on the user's waist.

[0086] The first electrical connection part 61 is disposed on the surface of the second flexible circuit board 60 facing the metal housing 34. The first electrical connection part 61 is used to electrically connect with the metal housing 34 and conduct the electrical stimulation massage current to the metal housing 34, so that the massage current of the first electrical connection part 61 can be conducted to the user's waist through the metal housing 34, thereby facilitating EMS massage when the user's waist contacts the metal housing 34. A protective space is formed between the metal housing 34 and the mounting part 321. Part of the second flexible circuit board 60 is located in the protective space and is protected by the outside of the metal housing 34, preventing the second flexible circuit board 60 from being subjected to external physical impact and extending the service life of the second flexible circuit board 60.

[0087] In the second embodiment, the second flexible circuit board 60 includes a connector 62 and a heating element 63 connected to the connector 62; the flexible circuit board 41 is provided with a heating element, on which a first electrical connection element 61 is exposed; the connector 62 is also used to electrically connect the first electrical connection element 61 to the main control board of the control module 121, so that the first electrical connection element 61 and the heating element 63 are integrated on the same second flexible circuit board 60, which can realize the electrical connection between the first electrical connection element 61 and the main control board of the control module 121 through the second flexible circuit board 60, avoiding the problem of wires easily getting tangled between the first electrical connection element 61 and the main control board of the control module 121.

[0088] The heating element 63 serves as the heating conductor of the flexible circuit board 41 and is arranged in a bent manner. When the heating element 63 is in operation, it outputs heat and conducts heat with the metal shell 34 so that the heat output by the heating element 63 can be conducted to the user's waist through the metal shell 34, thereby facilitating the heating element 63 to heat and massage the user's waist.
