[0050] The present utility model provides a heating device 10.

[0051] In the embodiments of the present utility model, as Figures 1 to 11 shown, the heating device 10 includes;

[0052] At least two heating units, including a first heating unit 40 and a second heating unit 50 detachably connected to the first heating unit 40;

[0053] The two heating units have a connection surface. A first clamping member 41 is convexly provided on the connection surface of the first heating unit 40, and an assembly groove 51 is formed on the connection surface of the second heating unit 50. A second clamping member 52 that cooperates with the first clamping member 41 is provided in the assembly groove 51;

[0054] The first clamping member 41 includes a first fixing column 411 and first clamping blocks 412 provided on opposite sides of the first fixing column 411;

[0055] The second clamping member 52 includes second clamping blocks 523 provided in the assembly groove 51 and cooperating with the first clamping blocks 412.

[0056] In this embodiment, the heating unit is used for generating heat and provides heating for the user by fitting with the user's body part. Among them, this embodiment includes at least two heating units, and the two heating units are detachably connected to each other. When a larger body part of the user needs heating, the first heating unit 40 and the second heating unit 50 are fixedly connected to increase the heating area; when different body parts of the user need heating, the first heating unit 40 and the second heating unit 50 are disassembled and separated, and then the first heating unit 40 and the second heating unit 50 are respectively applied to different body parts of the user to achieve heating of different body parts of the user.

[0057] The heating unit includes a housing 11 with an opening on one side and a connecting plate 12, and the connecting plate 12 covers the housing 11. The housing 11 is used to provide an installation space for other components of the heating unit and protect other components from external forces. The connecting plate 12 is used to provide an installation position for the connection structure of the heating unit. Among them, the connection surface is the surface where the two heating units face each other. A first clamping member 41 is convexly provided on the connection surface of the first heating unit 40, and an assembly groove 51 is provided on the connection surface of the second heating unit 50, and a second clamping member 52 that cooperates with the first clamping member 41 is provided in the assembly groove 51. Specifically, the first clamping member 41 includes a first fixing column 411 fixed to the connection surface of the first heating unit 40, and first clamping blocks 412 are respectively provided on opposite sides of the first fixing column 411. Among them, there is no limitation to only one set of the first clamping blocks 412, and specific details are not limited here. The second clamping member 52 includes a second clamping block 523, and the second clamping block 523 is fixed to the inner wall of the assembly groove 51 corresponding to the first clamping block 412. When the first clamping member 41 needs to be installed in the assembly groove 51, the first clamping blocks 412 of the first clamping member 41 are misaligned and docked with the second clamping blocks 523, so that the first clamping member 41 can extend into the assembly groove 51, and then the heating unit is rotated to make the first clamping blocks 412 and the second clamping blocks 523 located in the same vertical direction and abut against each other, so that the first heating unit 40 and the second heating unit 50 are fixed to each other. On the contrary, the first heating unit 40 and the second heating unit 50 are rotated in the opposite direction, and then the mutual disassembly between the first heating unit 40 and the second heating unit 50 is realized, so that the first heating unit 40 and the second heating unit 50 are separated.

[0058] In the technical solution of the present utility model, two heating units are detachably connected to each other. Among them, a first clamping member 41 is provided on the connecting surface of the first heating unit 40, an assembly groove 51 matching with the first clamping member 41 is formed on the connecting surface of the second heating unit 50, and a second clamping member 52 is arranged in the assembly groove 51. At the same time, the first clamping member 41 includes a first fixing column 411 and a first clamping block 412 arranged on the first fixing column 411. The second clamping member 52 includes a second clamping block 523 arranged in the assembly groove 51 and matching with the first clamping block 412. By inserting the first clamping member 41 of the first heating unit 40 into the assembly groove 51 of the second heating unit 50, and then rotating the first heating unit 40 relative to the second heating unit 50, the first clamping block 412 and the second clamping block 523 are abutted, so as to realize the mutual fixation between the first heating unit 40 and the second heating unit 50. On the contrary, the first heating unit 40 and the second heating unit 50 are rotated in the reverse direction, so as to realize the mutual disassembly between the first heating unit 40 and the second heating unit 50, so that the first heating unit 40 and the second heating unit 50 are separated, and then can act on the heating of different parts of the user's body respectively. Therefore, the practicability of the heating device 10 is effectively improved.

[0059] Further, as Figures 1 to 11 shown, a positioning ring 43 matching with the assembly groove 51 is further arranged on the connecting surface of the first heating unit 40. The positioning ring 43 is located in the assembly groove 51 and sleeved outside the second clamping member 52. In this embodiment, the positioning ring 43 is used to improve the connection stability between the first heating unit 40 and the second heating unit 50. The positioning ring 43 is arranged on the connecting surface of the first heating unit 40. It can be understood that the positioning ring 43 is sleeved outside the first clamping member 41. When the first heating unit 40 and the second heating unit 50 are assembled, the positioning ring 43 is inserted into the assembly groove 51, so as to effectively prevent the first heating unit 40 and the second heating unit 50 from moving in the horizontal or vertical direction, and then affecting the assembly efficiency of the first heating unit 40 and the second heating unit 50. Therefore, the practicability of the heating device 10 is effectively improved.

[0060] Further, the second clamping member 52 includes a second fixing column 521, a first clamping groove 522 is formed in the second fixing column 521, and the second clamping block 523 is arranged in the first clamping groove 522. It can be understood that the first clamping member 41 is inserted into the first clamping groove 522, and then rotated so that the first clamping block 412 abuts against the second clamping block 523.

[0061] Further, as Figures 1 to 11As shown, a second card slot 524 is provided on the outer wall of the second card block 523, and a third card block 42 is provided on the outer wall of the first engaging member 41 and is adapted to the second card slot 524. In this embodiment, the second card slot 524 and the third card block 42 improve the connection stability between the first heating unit 40 and the second heating unit 50. Specifically, the second card block 523 has a fixed end and a free end. The fixed end of the second card block 523 is fixed to the wall of the first card slot 522, and the free end of the second card block 523 is away from the wall of the first card slot 522. The second card slot 524 is provided at the free end of the second card block 523. At the same time, a third card block 42 adapted to the second card slot 524 is provided on the outer wall of the first engaging member 41. When the first heating unit 40 and the second heating unit 50 are rotationally fixed, the third card block 42 is located in the second card slot 524, thereby effectively restricting the relative rotation between the first heating unit 40 and the second heating unit 50, and thus effectively improving the connection stability of the heating device 10.

[0062] It should be noted that the third card block 42 or the second card block 523 is made of a flexible material with certain deformation, such as plastic, rubber, etc., and is not specifically limited here. Thus, when the first heating unit 40 and the second heating unit 50 rotate relative to each other, the third card block 42 or the second card block 523 will deform, and then the third card block 42 can move into the second card slot 524.

[0063] Furthermore, as Figures 1 to 8 shown, the heating unit further includes a main control board 13 provided in the housing 11 and a heating sheet 14 electrically connected to the main control board 13. The heating sheet 14 is attached to the outer wall of the housing 11. In this embodiment, the heating sheet 14 is a heating element of the heating unit. The heating sheet 14 is attached to the outer wall of the housing 11 to reduce the distance from the user's body, thereby reducing heat energy loss and improving the heating effect.

[0064] Furthermore, as Figures 1 to 8 shown, the housing 11 is provided with a first installation groove 151, and the heating sheet 14 is provided in the first installation groove 151. In this embodiment, the outer wall of the housing 11 is provided with the first installation groove 151, and the heating sheet 14 is fixed in the first installation groove 151, thereby effectively preventing the heating sheet 14 from being moved during use, and further affecting the heating effect of the heating device 10. Therefore, the practicability of the heating device 10 is effectively improved.

[0065] Furthermore, as Figures 1 to 8As shown in the figure, the heating unit further includes a heat conducting sheet 20. The heat conducting sheet 20 is disposed in the first installation groove 151 and is attached to the outer wall of the heating sheet 14. Thereby, it accelerates the transfer of the heat generated by the heating sheet 14 to the external environment. Since the heat conducting sheet 20 usually has a high thermal conductivity, it can quickly disperse and conduct the heat on the heating sheet 14 to other parts of the heating device 10 or the external environment, thereby improving the utilization rate of heat and the heating effect, and thus effectively improving the practicability of the heating device 10.

[0066] Furthermore, as Figures 1 to 8 shown in the figure, a second installation groove 152 is further formed in the bottom wall of the first installation groove 151, and the heating sheet 14 is disposed in the second installation groove 152. In this embodiment, the heating sheet 14 is disposed in the second installation groove 152, and the heat conducting sheet 20 is disposed in the first installation groove 151 and covers the heating sheet 14, thereby effectively isolating the influence of external factors on the heating sheet 14, such as air flow, dust accumulation, etc. Therefore, the heating sheet 14 is protected from damage and its service life is extended, and thus the practicability of the heating device 10 is effectively improved.

[0067] Furthermore, as Figures 1 to 8 shown in the figure, a circuit through hole 16 is formed in the bottom wall of the first installation groove 151, and the heating sheet 14 is electrically connected to the main control board 13 through the circuit through hole 16. In this embodiment, the circuit through hole 16 is used to provide a connection channel for the electrical connection between the heating sheet 14 and the main control board 13. The circuit through hole 16 is formed in the bottom wall of the first installation groove 151, so that when the heat conducting sheet 20 is installed in the first installation groove 151, the circuit through hole 16 will be completely covered, thereby effectively preventing external environmental media from entering the housing 11 and affecting the electrical components inside the heating device 10. Therefore, the practicability of the heating device 10 is effectively improved.

[0068] Furthermore, as Figures 1 to 8 shown in the figure, the heat conducting sheet 20 is snap-connected to the housing 11. In this embodiment, the heat conducting sheet 20 can be snap-fixed to the housing 11, can be screw-fixed, or can be glued. Preferably, the heat conducting sheet 20 is snap-connected to the housing 11. Compared with other fixing methods, snap fixing allows for a quick and stable connection between the heat conducting sheet 20 and the housing 11. And the user can easily complete the installation and disassembly of the heat conducting sheet 20 without using complex tools or performing cumbersome operations. This convenience not only improves the maintenance efficiency but also reduces the risk of component damage caused by improper operation. Therefore, the convenience of installation and disassembly of the heating device 10 and the structural stability are effectively improved.

[0069] Furthermore, the heat conducting sheet 20 is made of metal. Metal is a well-known excellent heat conducting material, and the movement of free electrons inside it enables heat to be rapidly transferred within the metal. Therefore, using a heat conducting sheet 20 made of metal can significantly improve the heat conduction efficiency of the heating device 10, enabling heat to be transferred from the heat source to the housing 11 more quickly and further dissipated into the surrounding environment, enhancing the heating effect. At the same time, metal materials usually have relatively high strength, hardness, and toughness, which makes the heat conducting sheet 20 not easily deformed or damaged when subjected to a certain amount of external force or impact. This further improves the structural stability of the heating device 10.

[0070] Furthermore, as Figures 1 to 8 shown, the heating unit further includes a temperature control probe 30 electrically connected to the main control board. The temperature control probe 30 is disposed in the first mounting groove 151. In this embodiment, the temperature control probe 30 is used to monitor the temperature of the heating sheet 14 in real time to ensure that the heating device 10 operates stably within the set temperature range. By disposing the temperature control probe 30 in the first mounting groove 151, it can more directly contact the heating sheet 14 and the surrounding heat environment, thereby achieving precise monitoring and control of the internal temperature of the heating device 10, and thus effectively improving the safety of the heating device 10.

[0071] Furthermore, as Figures 1 to 8 shown, a third mounting groove 153 is formed at the bottom of the first mounting groove 151, and the temperature control probe 30 is disposed in the third mounting groove 153. In this embodiment, the third mounting groove 153 provides an independent and protected space for the temperature control probe 30. In this space, the temperature control probe 30 can be protected from direct interference from the external environment, such as dust, moisture, or accidental collisions, thereby extending its service life and ensuring its measurement accuracy.

[0072] Furthermore, as Figures 1 to 8 and Figure 12 shown, the heating unit further includes an atmosphere lamp assembly. The atmosphere lamp assembly includes a light source 61 electrically connected to the main control board 13 and a light guiding member 62 covering the light source 61. The housing 11 is provided with a first mounting hole 171. The light source 61 is disposed inside the housing 11 and emits light toward the first mounting hole 171, and the light guiding member 62 is disposed in the first mounting hole 171. In this embodiment, the atmosphere lamp assembly is used to set off the usage environment of the heating device 10 to enhance the user experience. The light source 61 is the light emitting component of the atmosphere lamp assembly. The light source 61 is disposed inside the housing 11 and emits light toward the first mounting hole 171. The light guiding member 62 is used to evenly disperse the light emitted by the light source 61, thereby making the light emitted by the heating device 10 softer, effectively enhancing the user experience, and further improving the practicality of the heating device 10.

[0073] Further, the light guide member 62 includes a fixing plate 621 and a light guide bar 622 fixed to the fixing plate 621. Among them, the fixing plate 621 is attached to and fixed on the inner wall of the housing 11, and the light guide bar 622 is located in the first mounting hole 171. Furthermore, a light-emitting area of the heating device 10 is formed with the light guide bar 622 as a reference. According to user preferences, the light guide bar 622 can be adjusted into different shapes, thereby forming different light-emitting patterns. Therefore, the user experience is effectively improved, and the practicability of the heating device 10 is further improved.

[0074] Further, the light source 61 includes a plurality of lamp beads, and the lamp beads are fixed on the main control board 13 and are arranged at intervals corresponding to the shape of the light guide bar 622. In this embodiment, the light source 61 can be an LED light strip or a plurality of LED lamp beads. Preferably, the light source 61 is an LED lamp bead, and the LED lamp bead is fixed on the main control board 13. It can be understood that the LED lamp bead and the main control board 13 are integrally formed. Compared with the installation of the LED light strip, the setting of the LED lamp bead effectively saves the cost of the heating device 10 and improves the installation efficiency of the heating device 10. Therefore, the practicability of the heating device 10 is effectively improved.

[0075] Further, the atmosphere lamp assembly further includes a decorative cover 63. There is an installation space between the light guide bar 622 and the inner wall of the first mounting hole 171, and the decorative cover 63 is arranged in the installation space and is adapted to the shape of the installation space. In this embodiment, since the shape of the light guide bar 622 is diversified, there is a certain interval space between the light guide bar 622 and the first mounting hole 171, and this interval space seriously affects the visual effect of the overall shape of the heating device 10. Therefore, in this embodiment, a decorative cover 63 with a corresponding shape is arranged in this interval space, thereby effectively improving the visual shape integrity of the heating device 10 and further effectively enhancing the user experience. It should be explained that this interval space is the installation space for installing the decorative cover 63.

[0076] Further, as Figures 1 to 8 shown, the heating unit further includes a control button 70, and the housing 11 is further provided with a second mounting hole, and the control button 70 is arranged in the second mounting hole. Among them, the control button 70 is used to control the heating mode and the lighting effect of the heating device 10. Specifically, a second mounting hole is provided on the housing 11, the control button 70 is arranged in the second mounting hole, and is connected to the control board to emit a control signal through the control board, thereby controlling the heating effect of the heating sheet 14 and the lighting mode of the atmosphere lamp assembly.

[0077] Further, as Figures 1 to 8 shown, the heating unit further includes a battery 80 arranged in the housing 11, and the battery 80 is electrically connected to the main control board 13 to supply power to the heating sheet 14 and the atmosphere lamp assembly.

[0078] Further, as Figures 1 to 8 shown, the heating unit is semi-circular. In this embodiment, the overall shape of the heating unit can be semi-circular, square, oval, or other irregular shapes. However, it is preferably that the overall shape of the heating unit is semi-circular. Compared with other shapes, the semi-circular shape has no sharp corners, thus effectively improving the safety of use of the heating device 10. At the same time, when two heating units are combined, a complete circular heating device 10 can be formed, thereby improving the integrity of the overall shape of the heating device 10 and further enhancing the visual aesthetic feeling of the overall shape of the heating device 10.

[0079] The above are only the optional embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
