The present application may also be implemented in other ways. Furthermore, it should be understood that the expressions and terms used herein are for illustrative purposes only and should not be constrained.

[0023] As shown in Figures 1-5, a first embodiment of the present invention provides a neck-worn temperature control device 10 which may be worn around the neck of a person to regulate the temperature of the neck, for example, to achieve cooling. The neck-worn temperature control device 10 comprises a bracket 12, a temperature control assembly, a battery, and a circuit board installed within the bracket 12, the temperature control assembly and the battery being electrically connected to the circuit board to supply power to the operation of the temperature control assembly.

[0024] The bracket 12 comprises a first body 14 and at least one second body 16, the first body 14 and the second body 16 being rotatably connected to each other by a rotatable connection structure, allowing the second body 16 to rotate left and right relative to the first body 14, making it easy for the user to adjust the distance between the first body 14 and the second body 16 when wearing it. In other embodiments, the first body 14 and the second body 16 may be connected by other foldable structures, and the user can easily wear it by adjusting the distance between the two by moving the second body 16 relative to the first body 14. In this embodiment, two second bodies 16 are installed, and each of the two second bodies 16 is rotatably connected to both ends of the first body 14 by a rotatable connection structure, making the bracket 12 symmetrical and enhancing the aesthetic appearance of the product. Of course, in other embodiments, only one second body 16 may be installed, and the second body 16 is rotatably connected to one end of the first body 14 by a rotatable connection structure.

[0025] In the embodiment shown in the figure, the temperature control senburi comprises a cooling device installed in the first body 14 and a fan 18 provided in the second body 16, with one fan 18 installed in each second body 16. The neck-worn temperature control device 10 of the present invention can be cooled not only by the cooling device in the first body 14 but also by airflow cooling by the fan 18 in the second body 16, making it convenient for the user to use.

[0026] The cooling device comprises a heat dissipation member 20 provided within a bracket 12, a heat conduction member 22 provided on the inner wall of the bracket 12, a temperature control sheet attached between the heat dissipation member 20 and the heat conduction member 22, and a heat dissipation fan 26 provided at one end of the heat dissipation member 20. In other words, the heat conduction member 22 is connected to the temperature control sheet in a way that conducts heat, while the heat dissipation member 20 is located on the opposite side of the temperature control sheet from the heat conduction member 22 and is connected to the temperature control sheet in a way that conducts heat. More specifically, a semiconductor cooling sheet 24 is used as the temperature control sheet, an opening 28 is provided on the inner wall of the first main body 14 to correspond to the heat dissipation member 20, a mounting case 30 is connected to the opening 28, and the mounting case 30 can be fixed to the inner wall of the first main body 14 by means of a buckle or the like. The mounting case 30 is provided with a mounting position 32 for housing the semiconductor cooling sheet 24. The heat conduction member 22 has an arc shape that conforms to the neck of the human body and can be connected to the side of the mounting case 30 away from the heat dissipation member 20 by a buckle or the like. The heat dissipation member 20 comprises a bottom plate and a plurality of heat dissipation sheets formed extending from the bottom plate away from the semiconductor cooling sheet 24. The plurality of heat dissipation sheets are installed spaced apart, and a heat dissipation groove is formed between two adjacent heat dissipation sheets. In the longitudinal direction of the bracket 12, one end of the bottom plate extends from the heat dissipation sheet, and the heat dissipation fan 26 is positioned at least partially on the bottom plate so that the exhaust port of the heat dissipation fan 26 faces the heat dissipation groove, thereby dissipating heat from the heat dissipation sheet. After installation, the low-temperature end face of the semiconductor cooling sheet 24 is attached to the heat conduction member 22, and the high-temperature end face of the semiconductor cooling sheet 24 is attached to the bottom plate of the heat dissipation member 20. The outer surface of the first main body 14 is provided with heat dissipation holes 34 and air intake holes 36, respectively, corresponding to the heat dissipation member 20 and the heat dissipation fan 26. Heat generated by the heat dissipation member 20 is dissipated through the heat dissipation holes 34, and the heat dissipation fan 26 draws in air through the air intake holes 36.

[0027] To further stabilize the precise positioning of the cooling device and its various assemblies, positioning holes 38 are provided in the bottom plate, screw holes are provided in the inner wall of the first body 14 and the mounting case 30, respectively, and the heat dissipation member 20 is locked to the mounting case 30 by being fixed to the mounting case 30 through the screw holes and positioning holes 38 with screws. A positioning sheet 31 is further provided on the inner wall of the first body 14 to mount and position the heat dissipation fan 26 and to stabilize the mounting of the heat dissipation fan 26.

[0028] Preferably, when the decorative ring 40 is installed on the outer wall of the opening 28 and the mounting case 30 is connected to the first main body 14, the decorative ring 40 can serve a decorative purpose and enhance the overall aesthetic appearance of the product.

[0029] Furthermore, a partition sheet 42 is provided between the heat dissipation holes 34 and the air intake holes 36. The partition sheet 42 is positioned between the heat dissipation member 20 and the heat dissipation fan 26. The partition sheet 42 acts as a barrier, preventing heat generated by the heat dissipation member 20 from returning to the air intake of the heat dissipation fan 26 and affecting heat dissipation. It also works in cooperation with the positioning sheet 31 to position the heat dissipation fan 26.

[0030] As an option, the first main body 14 comprises a first outer case 14a and a first inner case 14b that are assembled and connected to each other, and the first outer case 14a and the first inner case 14b may be detachably fixed and connected by means of buckles, screws, etc., which is convenient for the user to remove.

[0031] In the embodiment shown in the figure, the fan 18 is installed at one end of the second body 16, away from the first body 14. An air intake port 43 is provided at the position of the second body 16 corresponding to the fan 18. The fan 18 is a centrifugal fan, meaning that the air inlet side and air outlet side of the fan 18 are perpendicular to each other, and the air inlet side of the fan 18 is positioned in the axial direction of the fan 18 and faces the air intake port 43. An air duct 44 is formed inside the second body 16 to correspond to the fan 18, with the air outlet side of the fan 18 facing the air duct 44. An exhaust port 46 is provided on the side wall of the air duct 44, arranged along the length of the second body 16. The exhaust port 46 may be installed inside the top and bottom walls of the second body 16. In this embodiment, the exhaust port 46 has a plurality of air outlet holes arranged at intervals along the length of the second body 16, and the air generated by the fan 18 is blown out from the exhaust port 46 via the air duct 44. In other embodiments, the exhaust port 46 may be implemented as a strip-shaped air outlet hole arranged along the length of the second body 16. Specifically, an isolation plate 48 is provided within the second body 16, and the surface of the isolation plate 48 extends along the length and width of the second body 16. The isolation plate 48 divides the empty cavity within the second body 16 into an air duct 44 and a storage space 50, thereby reducing the volume of the air duct 44, concentrating the airflow more effectively, and increasing the blown-out airflow force.

[0032] Preferably, guide portions 52 extending into the air duct 44 are provided on both side edges of one end of the isolation plate 48 that is close to the fan 18, and the surface of the guide portion 52 facing the air duct 44 is an arcuate surface, and the two guide portions 52 are located on the upper and lower sides of the air outlet side of the fan 18, respectively, to introduce the air generated by the fan 18 into the air duct 44, prevent the air generated by the fan 18 from swirling at the inlet of the air duct 44, and make the airflow smoother. Of course, in other embodiments, the guide portion 52 may be installed only on one side edge of the end of the isolation plate 48 that is close to the fan 18.

[0033] Furthermore, air guide grooves 54 are recessed at positions corresponding to the exhaust ports 46 on both sides of the side of the isolation plate 48 facing the air duct 44. The air guide grooves 54 extend along the length of the isolation plate 48, and each of the two air guide grooves 54 communicates with two guide sections 52, allowing the air generated by the fan 18 to be blown out of the exhaust ports 46 by the guiding action of the guide sections 52 and the air guide grooves 54, thereby making the airflow smoother. Naturally, in other embodiments, if the exhaust port 46 is provided on only one side of the air duct 44, an air guide groove 54 may be recessed at a position corresponding to the exhaust port 46 on one side edge of the isolation plate 48, and a guide section 52 is provided corresponding to the side edge where the air guide groove 54 is located.

[0034] In the embodiment shown in the figure, an air guide 56 and a windbreak sheet 58 are further provided inside the air duct 44. The air guide 56 extends along the length of the bracket 12, dividing the air duct 44 into two sub-air ducts 442, with exhaust ports 46 provided on the side walls of each of the two sub-air ducts 442. Specifically, the air guide 56 is V-shaped, its plate surface extends along the length and thickness of the second body 16, and may be formed integrally from the inner wall of the second body 16 or assembled and fixed to the inner wall of the second body 16. It may be a complete unit or formed by assembling multiple parts, and may be specifically adjusted during manufacturing depending on the product. In this embodiment, the air guide 56 extends integrally from the inner wall of the second body 16 to form a single whole. The tip of the air guide 56 is positioned close to the fan 18, facing the fan 18, so as to introduce the airflow generated by the fan 18 into the two sub-air ducts 442, and is positioned even closer to the top wall of the second body 16, thereby dividing the intake port of the air duct 44 into two parts of different sizes. The separated ends of the air guide 56 form two air guide sections, which extend to the top and bottom walls of the second body 16, respectively. The air generated by the fan 18 splits into two branches after passing through the air guide 56; one flows toward one side of the exhaust port 46 on the top wall, and the other flows toward one side of the exhaust port 46 on the bottom wall. The windbreak sheet 58 is installed at an angle inside the air duct 44, with one end facing the tip of the air guide 56 and the other end forming a curved section, which is connected between the two air outlet holes. The airflow directed toward one side of the bottom wall is again divided by the windbreak sheet 58, and the divided air is blown out from the exhaust ports 46 on both sides of the windbreak sheet 58. The installation of the air guide 56 and the windbreak sheet 58 allows the air generated by the fan 18 to be divided, thereby balancing the amount of air coming out at different positions in the corresponding air ducts 44 of the exhaust ports 46 and making the airflow at each point of the exhaust ports 46 more uniform.

[0035] In the embodiment shown in the figure, a battery 60 and a circuit board 62 are provided on the side of the isolation plate 48 located in the housing space 50. The battery 60, fan 18, and semiconductor cooling sheet 24 are electrically connected to the circuit board 62, and a switch 64, a charging port 66, and an LED light 68 are further provided on the circuit board 62. A control button 70, a socket 72, and a light-transmitting hole 74 are provided on the outer surface of the second main body 16 to correspond to the switch 64, charging port 66, and LED light 68, respectively. The control button 70 is connected to the switch 64, allowing the switch 64 to be turned on and off, and further controlling the switch and adjustment of the fan 18 and cooling device. The user can insert a data cable from the socket 72 into the charging port 66 to charge the battery 60. The light emitted by the LED light 68 can be emitted to the outside through the light-transmitting hole 74, making it easy for the user to check the remaining charge of the battery 60. Preferably, an LED light mounting chamber 69 is provided in the inner wall of the second body 16 at a position corresponding to the light-transmitting hole 74 and the LED light 68, and the light emitted can be more concentrated by mounting the LED light 68 inside the LED light mounting chamber 69.

[0036] Preferably, one side of the outer wall of the isolation plate 48 facing the second main body 16 at one end away from the guide portion 52 is bent and extended to form a positioning portion, and a lead wire passage hole 76 is provided in the positioning portion, and the lead wire passage hole 76 is for positioning the lead wire passing through the housing space 50, and prevents the wire body inside the bracket 12 from getting tangled.

[0037] Openings 78 are provided in both the inner and outer walls of the second body 16 corresponding to the fan 18, and a protective sheet 80 is installed in the openings 78. The protective sheet 80 is provided with a plurality of mesh holes 82 for the fan 18 to draw in air from the outside, and because the size of each mesh hole 82 is relatively small, the probability of the user's hair getting caught in the fan can be effectively reduced, thereby increasing the safety of using the product. In the embodiment shown in the figure, the plurality of mesh holes 82 are distributed in an annular shape on the protective sheet 80, and the plurality of mesh holes 82 are arranged in an annular shape multiple times, including an outer annular hole, an inner annular hole, and at least one circular intermediate hole located between the outer annular hole and the inner annular hole, in this embodiment, one circular intermediate hole is provided between the outer annular hole and the inner annular hole. Preferably, the diameter of the intermediate hole is smaller than the diameter of the outer annular hole, and the diameter of the inner annular hole is smaller than the diameter of the intermediate hole. Designing it this way makes it even more effective to prevent the user's hair from getting caught inside fan 18.

[0038] Furthermore, the protective sheet 80 is a metal sheet with a fold edge 84 provided on its periphery. The fold edge 84 is formed by folding the protective sheet 80 inward into the opening 78. A retaining portion 86 is provided on the periphery of the opening 78. The retaining portion 86 extends inward from the inner edge of the opening 78 to hold the fold edge 84 in place, preventing the protective sheet 80 from being excessively incorporated into the opening 78. A locking portion 88 further extends from the fold edge 84, and a notch 90 is provided in the retaining portion 86. The locking portion 88 engages with the notch 90, thereby ensuring that the protective sheet 80 is stably connected to the second body 16. The installation of the metal protective sheet 80 effectively increases the structural strength of the portion of the side wall of the second body 16 corresponding to the fan 18, and the structural arrangement of the multiple mesh holes 82 effectively prevents the user's hair from getting caught in the fan 18. In other embodiments, the protective sheet 180 may also be manufactured from other materials.

[0039] Furthermore, an enlarged portion is provided at the end of the locking portion 88, and after the locking portion 88 is engaged in the notch 90, the enlarged portion can be bent and hooked onto the side edge of the notch 90 to position it, further improving the connection stability of the protective sheet 80.

[0040] In the embodiment shown in the figure, a mounting bracket 92 is provided in the opening 78, and the mounting bracket 92 comprises a central part 94 and a plurality of connecting strips 96 connected around the central part 94, the ends of the connecting strips 96 are connected to the side wall of the opening 78, an air intake 43 is provided between two adjacent connecting strips 96, and the connecting strips 96 are provided with through holes 98 corresponding to the mesh holes 82 so as to prevent them from affecting the air inlet by the fan 18. The installation of the mounting bracket 92 further enhances the mounting stability of the protective sheet 80 in the opening 78, and when the mounting bracket 92 is provided in the opening 78, the mounting bracket 92 abuts against the protective sheet 80, preventing the protective sheet 80 from being excessively incorporated into the opening 78, and when the mounting bracket 92 is not provided in the opening 78, the engagement of the retaining part 86 and the folded edge 84 can prevent the protective sheet 80 from being excessively incorporated into the opening 78.

[0041] Since the rotational connection structure between the two second bodies 16 and the first body 14 is similar, the following explanation will only describe the rotational connection structure between one second body 16 and the first body 14 as an example.

[0042] The rotating connection structure comprises a first connecting member 100 and a second connecting member 102. The first connecting member 100 and the second connecting member 102 are engaged at one end by a swivel structure of a rotating shaft and a swivel hole to achieve a rotating connection, and their other ends are fixedly connected to the first body 14 and the second body 16, respectively, for example, by screws or buckles, thereby allowing the second body 16 to rotate left and right relative to the first body 14. Specifically, the first connecting member 100 comprises a first fixed part and two first swivel parts connected to one end of the first fixed part and installed at intervals, with swivel holes provided in the first swivel parts. The second connecting member 102 comprises a second fixed part and a second swivel part connected to one end of the second fixed part, with swivel holes provided in the second swivel parts. When installed, the first fixing part extends and is fixed to the end of the first body 14, the second fixing part extends and is fixed to the end of the second body 16, the second swivel part extends between the two first swivel parts, and the rotating shaft is inserted into the shaft hole, thereby achieving rotational connection.

[0043] Preferably, a limiting member is provided on the first connecting member 100 or the second connecting member 102, and the limiting member is for preventing the second body 16 from rotating too far relative to the first body 14. In the embodiment shown in the figure, the limiting member is a protruding block 104 installed on the outer circumferential wall of the first pivot section, and when the second body 16 rotates to a predetermined angle relative to the first body 14, the protruding block 104 comes into contact with the second fixed section and stops rotating, thereby limiting the rotation of the second body 16. Of course, in other embodiments, the limiting member may also be a protruding block 104 installed on the outer circumferential wall of the second pivot section, and when the second body 16 rotates to a predetermined angle relative to the first body 14, the protruding block 104 comes into contact with the first fixed section and stops rotating, thereby limiting the rotation of the second body 16.

[0044] Preferably, the rotating connection structure further includes a vibration damping member, which increases the frictional resistance of the second body 16 rotating relative to the first body 14, so that the second body 16 can be stably held at any rotational position relative to the first body 14, and prevents the second body 16 from rotating relative to the first body 14 due to the action of forces other than external forces. In the embodiment shown in the figure, the vibration damping member is a vibration damping ring 106, and two vibration damping rings 106 are installed, with the two vibration damping rings 106 sandwiched between the second rotating part and the two first rotating parts, respectively.

[0045] Since the connection portion between the first connecting member 100 and the second connecting member 102 is exposed outside the first body 14 and the second body 16, in order to avoid affecting the aesthetic appearance of the product, in the embodiment shown in the figure, a silica gel cover 108 is fitted outside the rotating connection structure, and fixing segments are provided at both ends of the silica gel cover 108, and the fixing segments at both ends and the intermediate portion of the silica gel cover 108 may be formed as an integral extension or connected by secondary injection molding, screw holes are provided in the fixing segments, and the two fixing segments are each covered on the outside of the fixing portions of the first connecting member 100 and the second connecting member 102 and fixed inside the first body 14 and the second body 16 with screws, and the intermediate portion of the silica gel cover 108 is fitted outside the connection portion between the first connecting member 100 and the second connecting member 102. Since the silica gel cover 108 is made of a soft material, it will elastically deform as the rotating connection structure rotates, and therefore will not affect the rotation of the rotating connection structure. The outer surfaces at both ends of the silica gel cover 108 may be positioned so that the outer surfaces of the first body 14 and the second body 16 transition smoothly, thereby enhancing the aesthetic appearance of the product.

[0046] As an option, the second body 16 comprises a second outer case 16a and a second inner case 16b that are assembled and connected to each other, and the second outer case 16a and the second inner case 16b may be detachably fixedly connected by a buckle, screw connection, or the like for the convenience of the user to remove them. An air duct 44 is formed between the second outer case 16a and the second inner case 16b, and an air guide 56 is provided on the inner wall of one of the second outer case 16a and the second inner case 16b. In this embodiment, the air guide 56 extends integrally from the second inner case 16b to form a single whole.

[0047] Figures 6-7 are schematic diagrams of a second embodiment of the present invention, the difference from the above embodiment being that in this embodiment, the air guide 56 is assembled and fixed to the inner wall of the second body 16. Referring to Figure 7, the air guide 56 consists of two parts: one part is integrally connected to the inner wall of the second inner case 16b, that is, the part away from the fan 18 is integrally connected to the inner wall of the second inner case 16b, and the other part is assembled and fixed to the inner wall of the second inner case 16b. Specifically, a positioning column 161 is provided on the inner wall of the second inner case 16b, and a positioning hole 561 is provided in the other part of the air guide 56. The engagement of the positioning column 161 and the positioning hole 561 fixes the other part of the air guide 56 to the inner wall of the second inner case 16b. Two L-shaped locking grooves 562 are provided at one end of the air guide 56 that is adjacent to the fan 18 and is integrally connected to the inner wall of the second inner case 16b. Two corresponding L-shaped locking parts 563 are provided at the end of the other part of the air guide 56 that is assembled and fixed to the inner wall of the second inner case 16b. The assembly stability of the air guide 56 is further enhanced by locking the two L-shaped locking parts 563 into the two L-shaped locking grooves 562. In addition, in this embodiment, the connecting strip 96 is curved in an arc shape according to the rotation direction of the fan 18, which further contributes to reducing air inlet resistance and reduces product noise. In order to more easily fold the silica gel cover 108 in accordance with the rotation of the rotary connection structure, this embodiment further provides corresponding folds, such as grooves, in the middle portion of the silica gel cover, thereby making it easier to fold and deform the silica gel cover 108 in accordance with the rotation of the rotary connection structure so as not to affect the rotation of the rotary connection structure. In this embodiment, the structure of the first main body 14 and other parts such as the cooling device are the same as in the above embodiment, so a detailed explanation is omitted here.

[0048] As shown in Figures 8-11, a third embodiment of the present invention provides a neck-worn temperature control device 10 which may be worn around the neck of a person to regulate the temperature of the neck, for example, to cool it. The neck-worn temperature control device 10 comprises a bracket, a temperature control assembly, a battery, and a circuit board installed within the bracket, the temperature control assembly and the battery being electrically connected to the circuit board to supply power to the operation of the temperature control assembly.

[0049] The bracket comprises a first body 12 and at least one second body 14, the first body 12 and the second body 14 being rotatably connected by a rotatable connection structure, allowing the second body 14 to rotate left and right relative to the first body 12, making it convenient for the user to wear. In this embodiment, two second bodies 14 are installed, and each of the two second bodies 14 is connected to both ends of the first body 12 by a rotatable connection structure, giving the bracket a symmetrical structure and enhancing the aesthetic appearance of the product. Of course, in other embodiments, only one second body 14 may be installed, and this second body 14 is rotatably connected to one end of the first body 12 by a rotatable connection structure.

[0050] In the embodiment shown in the figure, the temperature control basin is equipped with a fan 16 and a cooling device. Two fans 16 are installed, each of which is located in one of two second bodies 14. The cooling device is located in the first body 12. This allows the neck-worn temperature control device 10 of the present invention to be cooled not only by the cooling device in the first body 12, but also by airflow provided by the fan 16 in the second body 14, making it convenient for the user.

[0051] The cooling device comprises a heat dissipation member 18 provided inside the first main body 12, a heat conduction member 20 provided on the inner wall of the first main body 12, a temperature control sheet attached between the heat dissipation member 18 and the heat conduction member 20, and a heat dissipation fan 24 provided at one end of the heat dissipation member 18 for dissipating heat from the high-temperature end of the temperature control sheet. In other words, the heat conduction member 20 is connected to the temperature control sheet in a way that conducts heat, while the heat dissipation member 18 is located on the opposite side of the temperature control sheet from the heat conduction member 20 and is connected to the temperature control sheet in a way that conducts heat. More specifically, the temperature control sheet is a semiconductor cooling sheet 22, an opening is provided in the inner wall of the first main body 12 to correspond to the heat dissipation member 18, a mounting case is connected to the opening, and a mounting position for housing the semiconductor cooling sheet 22 is provided in the mounting case, the heat conduction member 20 is connected to the semiconductor cooling sheet 22 in a way that conducts heat, has an arc shape that fits the neck of the human body, and is connected to the side of the mounting case away from the heat dissipation member 18 by a buckle or the like. The heat dissipation member 18 comprises a base plate and a plurality of heat dissipation sheets formed extending from the base plate toward the side away from the semiconductor cooling sheet 22. The plurality of heat dissipation sheets are installed spaced apart, and a heat dissipation groove is formed between two adjacent heat dissipation sheets. In the longitudinal direction of the bracket, one end of the base plate extends from the heat dissipation sheet, and the heat dissipation fan 24 is positioned at least partially on the base plate so that the exhaust port of the heat dissipation fan 24 faces the heat dissipation groove, thereby dissipating heat from the heat dissipation sheet. After installation, the low-temperature end face of the semiconductor cooling sheet 22 is attached to the heat conduction member 20, and the high-temperature end face of the semiconductor cooling sheet 22 is attached to the base plate of the heat dissipation member 18. The outer surface of the first main body 12 is provided with heat dissipation holes 26 and air intake holes 28, respectively, corresponding to the heat dissipation member 18 and the heat dissipation fan 24. Heat generated by the heat dissipation member 18 is dissipated through the heat dissipation holes 26, and the heat dissipation fan 24 draws in air through the air intake holes 28.

[0052] As an option, the first main body 12 comprises a first outer case 12a and a first inner case 12b that are assembled and connected to each other, and the first outer case 12a and the first inner case 12b may be detachably fixed and connected by a method such as a buckle or screw connection, which is convenient for the user to remove.

[0053] In the embodiment shown in the figure, the fan 16 is installed at one end of the second body 14 away from the first body 12, and intake ports 31 for the fan 16 to draw in air are provided on the inner and outer walls of the second body 14 corresponding to the position of the fan 16. An air duct 30 is formed inside the second body 14 to correspond to the fan 16, and exhaust ports 32 are provided on the side walls of the air duct 30, arranged along the length of the second body 14. The exhaust ports 32 may be installed inside the top and bottom walls of the second body 14, and in this embodiment, the exhaust ports 32 have a plurality of air outlet holes arranged at intervals along the length of the second body 14, and the air generated by the fan 16 is blown out from the exhaust ports 32 through the air duct 30. In other embodiments, the exhaust ports 32 may be implemented as strip-shaped air outlet holes arranged along the length of the second body 14.

[0054] Furthermore, a partition member 34 is provided within the second body 14, and the plate surface of the partition member 34 extends along the length and width directions of the second body 14. The partition member 34 divides the empty cavity within the second body 14 into an air duct 30 and a housing space, which are spaced apart along the thickness direction of the second body 14, and the air duct 30 is located on the inside of the second body 14. This reduces the volume of the air duct 30, allowing for greater concentration of airflow and a larger airflow force. Batteries and circuit boards may be installed within the housing space, avoiding any interference with the airflow.

[0055] Furthermore, an air guide 36 is provided within the air duct 30, and an air guide 56 extends along the length of the bracket. Specifically, the air guide 36 is V-shaped, its plate surface extends along the length and thickness of the second body 14, and may be formed integrally from the inner wall of the second body 14, or assembled and fixed to the inner wall of the second body 14, and may be formed as a complete whole or by assembling multiple parts, and specifically can be adjusted to suit the product during manufacturing. In this embodiment, the air guide 36 is fixed to the inner wall of the second body 14 with screws. Specifically, the tip of the air guide 36 is positioned close to the fan 16, facing the fan 16, and is also positioned closer to the top or bottom wall of the second body 14, thereby dividing the air intake of the air duct 30 into two parts of different sizes, with the separated ends of the air guide 36 extending to the top and bottom walls of the second body 14, respectively. The air generated by the fan 16 passes through the air guide 36 and then splits into two branches: one flows toward one side of the exhaust port 32 on the top wall, and the other flows toward one side of the exhaust port 32 on the bottom wall before being blown out of the exhaust port 32.

[0056] As an option, the second main body 14 comprises a second outer case 14a and a second inner case 14b that are assembled and connected to each other, and the second outer case 14a and the second inner case 14b may be detachably fixed and connected by means of buckles, screws, or the like, which is convenient for the user to remove.

[0057] In the embodiment shown in the figure, the partition member 34 is fixed to the inner wall of the second outer case 14a with screws, and the air guide 36 is fixed to the inner wall of the second inner case 14b with screws. For example, screw holes are provided in the air guide 36, and corresponding studs are installed on the inner wall of the second inner case 14b, and the air guide 36 is screwed to the studs through the screw holes with screws.

[0058] In some embodiments, the temperature control assemblies further include control buttons for simultaneously controlling the fan 16 and the cooling device. The control buttons are electrically connected to a circuit board and may be mounted on the outer surface of the first body 12 or the second body 14 for user convenience. The control buttons can control the fan 16 and the cooling device in multiple control modes. For example, a short press of the control button can switch the control fan 16 between on, different stages, and off operating modes, while a long press of the control button can switch the cooling device between on and off operating modes. Figure 12 is a schematic diagram showing the circuit principle of the temperature control assembly. In an optional embodiment, a main control chip U6 is provided on the circuit board, and the circuit corresponding to the control button includes a touch chip U3. The reference voltage terminal VREF of the main control chip U6 is connected to the control terminal LX of the touch chip U3 by a booster circuit 81. The booster circuit 81 includes a first capacitor C16 and a second capacitor C15 connected in parallel, a first resistor R30 and a second resistor R31 connected in series and then connected in parallel to the second capacitor C15, and the node between the first resistor R30 and the second resistor R31 is connected to the feedback terminal FB of the touch chip U3. The main control chip U6 includes a first fan control terminal FANA-EN and a second fan control terminal FANB-EN, which are connected to the fans respectively, and a temperature control terminal COLD-EN, which is connected to the cooling device. The first fan control terminal FANA-EN is connected to the motor of one fan by the first switch tube Q1, the second fan control terminal FANB-EN is connected to the motor of the other fan by the second switch tube Q2, and the temperature control terminal COLD-EN is connected to the cooling device by the third switch tube Q13. The touch chip U3 detects the user's button time data and transmits it to the main control chip U6. After the main control chip U6 identifies the current button operation, it transmits the corresponding control command via the first fan control terminal FANA-EN, the second fan control terminal FANB-EN, or the temperature control terminal COLD-EN, thereby switching the operating modes of the control fan 16 and the cooling device. As an option, the first switch tube Q1, the second switch tube Q2, and the third switch tube Q13 may each be field-effect transistors.

[0059] Furthermore, the temperature control assemblies may also be equipped with a buzzer, which is electrically connected to the circuit board and emits a sound when the control button is pressed, thereby making it easier for the user to perceive that the button has been activated. For example, if the control button is pressed for a long time, the buzzer will emit a sound for a long time, and if the control button is pressed for a short time, the buzzer will emit a sound for a short time.

[0060] Furthermore, the temperature control assembly is further equipped with a temperature sensor, which may be installed inside the first main body 12 and electrically connected to a circuit board, for sensing the operating temperature of the semiconductor cooling sheet 22. If the temperature sensor detects that the temperature of the semiconductor cooling sheet 22 is too high, it can control the cooling device to stop its operation, thereby preventing the outer casing of the product from melting and creating a hazard when the temperature is too high. Referring to Figure 13, in an optional embodiment, the temperature sensor is equipped with a thermistor RNTC connected to the temperature-sensitive control terminal NTC-DATE of the main control chip U6. The resistance value of the thermistor RNTC changes in accordance with the change in the temperature of the semiconductor cooling sheet 22, and the main control chip U6 can determine whether the current temperature is too high in accordance with the change in the resistance value of the thermistor RNTC, thereby avoiding failure or danger caused by the semiconductor cooling sheet 22 being too high.

[0061] Furthermore, when the cooling device is controlled and turned off by operating a control button, the heat dissipation fan 24 may continue to operate for a predetermined time after the semiconductor cooling sheet 22 stops operating, for example, after 5 to 10 seconds before stopping, thereby thoroughly dissipating heat from the heat dissipation member 18 and improving product quality. The implementation method for controlling the semiconductor cooling sheet 22 to stop its operation and then controlling the heat dissipation fan 24 to stop its operation after a predetermined time may be such that, after the main control chip U6 receives the operation to control and turn off the cooling device, the temperature control terminal COLD-EN controls the semiconductor cooling sheet 22 to stop its operation, and at the same time starts timing, and after timing until a predetermined time is reached, the first fan control terminal FANA-EN and the second fan control terminal FANB-EN control the fans to stop their operation.

[0062] In some other embodiments, the temperature control assemblies may consist only of a fan 16, or only of a cooling device. When the temperature control assemblies consist of a fan 16 and a cooling device, multiple control buttons may be provided to control the fan 16 and the cooling device separately. Alternatively, when multiple control buttons are provided, there may be multiple control methods in which one control button controls startup and shutdown, and the other control buttons control the stages. The control buttons may also have multiple trigger control methods.

[0063] In the embodiment shown in the figure, the rotary connection structure comprises a first connecting member 38 and a second connecting member 40. One end of the first connecting member 38 and the second connecting member 40 that is close to each other is rotatably connected to each other, and the other ends of the first connecting member 38 and the second connecting member 40 that are far apart from each other are fixedly connected to the first body 12 and the second body 14, respectively. Furthermore, the end faces of the one end of the first connecting member 38 and the second connecting member 40 that is close to each other are provided with teeth 42 and projections 44 that engage with each other. When the second body 14 rotates relative to the first body 12, the projections 44 are engaged in the tooth grooves of the teeth 42 to enable positioning, thereby dividing and fixing it into multiple parts. This makes it easy to adjust the wearing width for fixing the two second bodies 14 and prevents abnormal rotation. Preferably, the first connecting member 38 and the second connecting member 40 are each made of metal material, which has high strength and wear resistance.

[0064] More specifically, the first connecting member 38 comprises a first connecting portion 46 and two pivot portions 48 connected to one end of the first connecting portion 46 adjacent to the second connecting member 40 and installed at intervals, with the teeth portion 42 installed on the end face of one end of the pivot portion 48 adjacent to the second connecting member 40. Preferably, the end face of one end of the pivot portion 48 adjacent to the second connecting member 40 is installed as a protruding arc-shaped surface, and the teeth portion 42 comprises a plurality of racks arranged at intervals according to the rotational direction, with tooth grooves formed between two adjacent racks. A pivot groove is formed between the two pivot portions 48, and a first shaft hole 50 is provided in the pivot portion 48. The second connecting member 40 comprises a second connecting portion 52 and a rotating portion 54 connected to one end of the second connecting portion 52 adjacent to the first connecting member 38, with a second shaft hole 58 provided in the rotating portion 54. Preferably, rotating shafts 56 are provided on both sides of the rotating part 54, for example, the rotating shafts 56 are installed to pass through the rotating part 54, and the second shaft hole 58 is installed to pass through the rotating shafts 56. The projection 44 is installed on the end face of one end of the second connecting part 52 that is close to the first connecting member 38, and preferably the projection 44 is a convex ridge that extends along the axial direction of the rotating connection structure.

[0065] When installing, the rotating part 54 and the rotating shaft 56 extend into the pivot groove, bringing the projection 44 into contact with the tooth portion 42, and further engaging the projection 44 within the tooth groove of the tooth portion 42. At this time, the first shaft hole 50 is aligned with the second shaft hole 58, and the first connecting member 38 is rotated to the second connecting member 40 by a pin shaft through the first shaft hole 50 and the second shaft hole 58.

[0066] Preferably, the pivot portion 48 is provided with protruding blocks 49 at both ends of its arc-shaped surface, and the teeth portion 42 is located between the two protruding blocks 49 on the arc-shaped surface. The protruding blocks 49 are designed to contact the second connecting portion 52 when the second body 14 rotates a certain angle relative to the first body 12, so as to prevent the second body 14 from rotating too much relative to the first body 12.

[0067] Preferably, the rotary connection structure further includes a vibration damping member, for example, a vibration damping rubber ring 60, two of which are installed, the two vibration damping rubber rings 60 located on both sides of the rotating part 54, the vibration damping rubber rings 60 fitted outside the rotating shaft 56 and positioned between the rotating part 54 and the pivot part 48, for example, the vibration damping rubber rings 60 are pushed out and connected between the rotating part 54 and the pivot part 48, increasing the frictional resistance of the rotary connection structure and further improving rotational stability.

[0068] In the embodiment shown in the figure, a protective cover is provided on the outside of the rotating connection structure to prevent the user's hair from getting caught in the rotating shaft. Specifically, the protective cover comprises a soft rubber cover 62 and hard rubber members 64 fixed to both ends of the soft rubber cover 62, with the two hard rubber members 64 covering the outside of the first connecting member 38 and the second connecting member 40, respectively. By further installing hard rubber members 64 on both ends of the soft rubber cover 62 (for example, by injection molding), it is possible to more effectively prevent gaps from forming between both ends of the soft rubber cover 62 and the ends of the first body 12 or the second body 14 when the soft rubber cover 62 deforms, and to prevent detachment, and the appearance of the product is made more aesthetically pleasing.

[0069] First screw holes 66 are provided in the first connecting portion 46 and the second connecting portion 52, and second screw holes 68 are provided in the two hard rubber members 64 so as to correspond to the first screw holes 66 on the two connecting portions. Studs 70 are provided on the inner walls of the first body 12 and the second body 14, respectively. When installing, one end of the first connecting portion 46 away from the second connecting member 40 extends to the end of the first main body 12, and one end of the second connecting portion 52 away from the first connecting member 38 extends to the end of the second main body 14. By screwing the first connecting member 38 and the corresponding hard rubber member 64 to the stud 70 through the corresponding first screw holes 66 and 2 screw holes 68, the first connecting member 38 and the corresponding hard rubber member 64 are fixedly connected to the first main body 12 through the first screw holes 66, 2 screw holes 68 and stud 70, and the second connecting member 40 and the corresponding hard rubber member 64 are fixedly connected to the second main body 14 through the first screw holes 66, 2 screw holes 68 and stud 70.

[0070] Preferably, an annular groove 72 is provided in the middle of the soft rubber cover 62, and when installed, the annular groove 72 is positioned to correspond to the rotational connection position (i.e., the pin axis position) of the rotational connection structure, making the soft rubber cover 62 more easily deformable and bendable when the second body 14 rotates relative to the first body 12.

[0071] To improve the adhesive stability between the soft rubber cover 62 and the hard rubber member 64, in the embodiment shown in the figure, a positioning groove 74 is provided on the outside of the connection end between the hard rubber member 64 and the soft rubber cover 62. During injection molding, a portion of the rubber of the soft rubber cover 62 is bonded to the positioning groove 74, thereby improving the adhesive stability between the two.

[0072] As shown in Figures 14-18, a fourth embodiment of the present invention provides a neck-worn temperature control device that can be worn around the neck of a person, thereby making it easy for the user to carry it with them and regulate the temperature of their body, particularly their neck and face, anytime and anywhere. The neck-worn temperature control device of this embodiment is generally U-shaped and consists of two air blowing modules 10 and a temperature control module 30 installed between the two air blowing modules 10. When worn around the neck, the temperature control module 30 is positioned at the nape of the neck, and the two air blowing modules 10 are positioned on the left and right sides of the neck, thereby regulating the temperature of the neck, head, etc., comprehensively and improving the user's comfort. In some embodiments, the temperature control module 30 may be omitted from the neck-worn temperature control device of the present invention.

[0073] In this embodiment, the air blower module 10 and the temperature control module 30 are rotatably connected to facilitate adjustment of the angle between them, thereby adjusting the configuration of the neck-worn temperature control device when in use, and in particular facilitating the adjustment of the air outlet angle and air outlet distance of the air blower module 10, as well as facilitating the wearing and storage of the neck-worn temperature control device. More preferably, a protective cover 20 is fitted at the connection point between the air blower module 10 and the temperature control module 30 to give the overall appearance of the product a smooth and beautiful finish, and the protective cover 20 may be made of a soft rubber material, such as silicone rubber. More preferably, an annular groove 22 is formed in the protective cover 20 so that the protective cover 20 can easily deform in response when the air blower module 10 and the temperature control module 30 rotate relative to each other, making it convenient for the user to rotate. In this embodiment, the annular groove 22 is located on the outer surface of the protective cover 20, while in other embodiments, the annular groove 22 may be located on the inner surface of the protective cover 20. In other embodiments, the air blower module 10 and the temperature control module 30 may be fixedly connected, and the embodiment is not limited to a specific example.

[0074] Referring to Figures 16 and 17 simultaneously, the blower module 10 comprises a second body 12, a fan 14 installed inside the second body 12, a circuit board 16, and a battery module 18, and the fan 14, circuit board 16, and battery module 18 are electrically connected.

[0075] Along the length of the neck-worn temperature control device, the width of the device gradually decreases from its ends to the center, resulting in a narrower contact area between the center of the device (i.e., the temperature control module 30) and the neck, thereby improving wearing comfort. The ends of the device (i.e., the air blower module 10) are wider, allowing for the placement of larger fans 14 to increase the air outlet volume. Correspondingly, the second body 12 has a tapered structure, and the width of its internal space gradually decreases from its outer end (i.e., the end away from the temperature control module 30) to its inner end (i.e., the end connected to the temperature control module 30). The fan 14 is preferably a centrifugal fan and is installed at the outer end of the second body 12, i.e., at the widest point.

[0076] In this embodiment, the second body 12 consists of a first inner case 12a and a first outer case 12b that are detachably connected, with the first inner case 12a facing the neck and the first outer case 12b facing away from the neck. A partition member 13 is installed between the first inner case 12a and the first outer case 12b, and the partition member 13 is thin and plate-like, extending along the length of the second body 12. In the embodiment shown in the figure, the partition member 13 is bent toward one side end of the fan 14 until it is connected to the first outer case 12b. A first chamber 120 is formed between the first inner case 12a and the partition member 13 for installing the fan 14 and forming an air duct for the fan 14, and a second chamber 122 is formed between the first outer case 12b and the partition member 13 for installing a circuit board 16 and a battery module 18.

[0077] The installation of the partition member 13 separates the air duct of the fan 14 from the battery module 18, thus preventing the battery module 18 from affecting the airflow and ensuring the electrical safety of the battery module 18. Furthermore, the installation of the partition member 13 reduces the air duct (i.e., the first chamber 120) through which the airflow actually flows within the second body 12 by approximately half relative to the internal space of the second body 12, effectively improving the airflow velocity and further increasing the amount of air at the outlet. Additionally, because the second body 12 has a tapered shape, the first chamber 120 and the second chamber 122 exhibit similar tapered structures. As a result, the size of the air duct gradually decreases along the airflow, exhibiting an accelerating reduction effect on the airflow.

[0078] The second body 12 has an intake port 124 corresponding to the fan 14 and an exhaust port 126 corresponding to the air duct. The airflow enters the second body 12 from the intake port 124 due to the action of the fan 14, flows along the first chamber 120, accelerates, and is then blown outward from the exhaust port 126. In the embodiment shown in the figure, the intake port 124 is formed on the inner and outer side walls of the second body 12, that is, on the first inner case 12a and the first outer case 12b, respectively, and the exhaust port 126 is formed on the upper and lower side walls of the second body 12, that is, on the upper and lower edges of the first inner case 12a, respectively. As a result, air is blown out simultaneously from both the upper and lower sides, with some of the airflow hitting the sides of the neck and face upwards, and some of the airflow hitting the sides of the neck and the front of the chest downwards.

[0079] More preferably, along the length of the second body 12, the exhaust port 126 covers the entire air duct, widening the air outlet range. More preferably, a metal protective cover 128 is provided over the intake port 124 of the first outer case 12b, with multiple mesh holes formed in the protective cover 128 to ensure that outside air can enter the second body 12 through the mesh holes, while also preventing impurities such as hair from falling into the second body 12 and affecting the safe operation of the fan 14, and at the same time making the overall appearance of the product more aesthetically pleasing. Note that the intake port 124 may be installed only on the inner wall or outer wall of the second body 12, or the exhaust port 126 may be installed only on the upper wall or lower wall of the second body 12.

[0080] Corresponding to the tapered structure of the second body 12, the width of the partition member 13 gradually decreases along the length of the second body 12 toward its inner end. In this embodiment, air is blown out from both the upper and lower sides of the second body 12, and air guide portions 130 extend toward the first chamber 120 from the upper and lower side edges of one end of the partition member 13 that is close to the fan 14. The air guide portions 130 have an arc-shaped structure and are intended to guide the airflow from the fan 14 toward the first chamber 120. When air is blown out from one side of the second body 12, the air guide portions 130 extend from the partition member 13 only to the edge corresponding to the air outlet side of the second body 12. Shielding plates 132 extend toward the second chamber 122 from the upper and lower side edges of one end of the partition member 13 that is close to the fan 14, and an installation chamber 134 is formed between the two shielding plates 132. The battery module 18 is fixed inside the mounting chamber 134 and is relatively close to the outer end of the second main body 12, while the circuit board 16 is fixed to the partition member 13 with screws or the like and is installed relatively close to the inner end of the second main body 12.

[0081] Along the length of the second body 12, the fan 14, battery module 18, and circuit board 16 are installed in order, with the fan 14 located at the outer end of the second body 12 and the battery module 18 installed adjacent to the fan 14. In this way, the battery module 18 is positioned as close as possible to the outer end of the second body 12, allowing for a larger mounting space, and the battery module 18 can have a larger size and capacity, ensuring sufficient range. The circuit board 16 may also use a fine-strip structure to fit into the internal space of the second body 12. By arranging the fan 14, battery module 18, circuit board 16, etc., based on the tapered structure of the second body 12, the internal space of the second body 12 is effectively utilized, making the overall structure more compact and rational.

[0082] Referring simultaneously to Figure 18, the battery module 18 comprises a battery 180 and a protective plate 182 electrically connected to the battery 180. The battery 180 has a block-like structure and is preferably a polymer rechargeable battery. Correspondingly, the circuit board 16 is provided with a charging port 160 for charging the battery 180 by connecting to an external power source. The protective plate 182 is strip-shaped and installed on the side edge of the battery 180. In this embodiment, the protective plate 182 is located on the outer edge of the battery 180, i.e., closer to the fan 14. Of course, in other embodiments, the protective plate 182 may be located on the inner edge, upper edge, or lower edge of the battery. The protective plate 182 and the positive and negative electrodes of the battery 180 are connected by two metal conductive sheets 184. A protective chip 186 is installed on the protective plate 182 to provide over-discharge protection, over-charge protection, short-circuit protection, over-current protection, etc., for the battery 180, ensuring the safe use and service life of the battery 180. Furthermore, the protective plate 182 is equipped with positive and negative lead wires 188 for connecting to the circuit board 16.

[0083] In the embodiment shown in the figure, a battery module 18 is installed in the second chamber 122 of each blower module 10 to supply power to the fan 14 of the blower module 10, that is, each fan 14 is powered independently. Alternatively, only one battery module 18 may be installed to power both fans 14 simultaneously. More preferably, one of the second bodies 12 is equipped with a control button 40 for controlling the on / off state of the fan 14, and the control button 40 is electrically connected to the circuit board 16, facing the location of the circuit board 16. Specifically, in the embodiment of this application, the two blower modules 10 are controlled by one control button 40, and therefore, a circuit board 16 connected to the switch button 40 is provided only in one of the second bodies 12. Naturally, in other embodiments, if it is to achieve independent control of the two blower modules 10, a circuit board 16 and a control button 40 electrically connected to the circuit board may be installed in each of the two second bodies 12. More preferably, an LED light 162 is further installed on the circuit board 16, and a light-transmitting hole 129 is installed in the second main body 12 at a position corresponding to the LED light 162. The LED light 162 may be used as an operating status indicator for a neck-worn temperature control device, a light for illumination in dark places, etc.

[0084] As shown in Figure 16, the temperature control module 30 comprises a first body 32, a temperature control sheet 34, a heat conduction member 36, a heat dissipation member 38, and a heat dissipation fan 39 installed inside the first body 32. The first body 32 and the second body 12 may be defined as brackets for a neck-worn temperature control device.

[0085] The temperature control sheet 34 is a semiconductor device and is electrically connected to the battery module 18 by a circuit board 16. Based on the thermoelectric effect of semiconductors, when energized, the temperature control sheet 34 forms a low-temperature end and a high-temperature end on its opposing sides, respectively. The heat conduction member 36 is attached to the low-temperature end of the temperature control sheet 34 to transmit cold and heat to the outside, and the heat dissipation member 38 is attached to the high-temperature end of the temperature control sheet 34 to conduct heat to the outside. More preferably, a protrusion 320 is formed protruding from the inner wall of the first body 32, and the heat conduction member 36 is connected to the protrusion 320 and extends from the inner wall of the first body 32. When the neck-worn temperature control device of the present invention is in use, the heat conduction member 36 contacts the neck of the human body instead of the inner wall of the first body 32, and transmits the cold and heat generated by the temperature control sheet 34 directly to the neck.

[0086] The heat dissipation member 38 and the heat dissipation fan 39 are arranged sequentially along the length of the first body 32. The heat dissipation member 38 comprises a plurality of heat dissipation sheets, which may be made of a metal material such as aluminum or copper or an alloy thereof with good thermal conductivity, and can absorb heat from the temperature control sheet 34 and dissipate it into the surrounding air. Heat dissipation grooves 380 are formed between adjacent heat dissipation sheets, and the heat dissipation grooves 380 extend along the length of the first body 32 and are installed facing the air outlet side of the heat dissipation fan 39. More preferably, heat insulating sheets 382 are installed on both the upper and lower sides of the heat dissipation member 38. The heat insulating sheets 382 separate the heat dissipation member 38 from the upper and lower side walls of the first body 32, preventing heat from the heat dissipation member 38 from being transferred to the first body 32 and affecting the wearing comfort of the neck-worn temperature control device of the present invention.

[0087] The cooling fan 39 is preferably a centrifugal fan. An air intake hole 322 is formed in the outer wall of the first body 32 to correspond to the cooling fan 39, and a cooling hole 324 is formed to correspond to the heat dissipation member 38. Cold air from outside enters the first body 32 through the air intake hole 322 due to the action of the cooling fan 39, exchanges heat with the heat dissipation member 38, and then flows out of the first body 32 through the cooling hole 324, thereby continuously and repeatedly dissipating heat from the temperature control sheet 34 to the outside. More preferably, a partition sheet 326 is formed in the outer wall of the first body 32, extending inward. The partition sheet 326 is located between the cooling hole 324 and the air intake hole 322, separating the cold air drawn into the first body 32 from the hot air after heat exchange with the heat dissipation member 38, thereby ensuring a heat dissipation effect.

[0088] More preferably, the control button 40 and the temperature control module 30 are electrically connected by a circuit board 16 to control the on / off switching of the temperature control module 30. The circuit board 16 is equipped with control circuits connected to the fan 14 of the blower module 10, the temperature control sheet 34 of the temperature control module 30, the heat dissipation fan 39, etc., and the on / off switching of the fan 14, the temperature control sheet 34, and the heat dissipation fan 39 can be controlled by controlling the pressing of the button 40. More preferably, when the temperature control module 30 is turned off, the control circuit delays the off-time of the heat dissipation fan 39 by a certain period of time, for example, 5 to 10 seconds, compared to the off-time of the temperature control sheet 34, so that after the temperature control sheet 34 stops operating, the heat dissipation fan 39 continues to operate for a certain period of time to ensure that sufficient heat is dissipated to the outside. The implementation method for controlling the temperature control sheet 34 to stop its operation, and then controlling the heat dissipation fan 39 to stop its operation after a predetermined time, may also involve a main control chip being provided on the circuit board 16. After the main control chip controls the temperature control module 30 and obtains the operation to turn it off, the control terminal of the thermoelectric sheet controls the temperature control sheet 34 to stop its operation, and at the same time starts timing. After timing until a predetermined time is reached, the control terminal of the heat dissipation fan controls the heat dissipation fan 39 to stop its operation.

[0089] In this embodiment, the first body 32 comprises a second inner case 32a and a second outer case 34a that are detachably connected, with the second inner case 32a facing the neck and the second outer case 34a facing away from the neck. The protrusion 320 is formed on the second inner case 32a, and the heat dissipation holes 324, air supply holes 322, and partition sheet 326 are formed on the second outer case 34a. The second body 12, together with the first body 32, constitutes the bracket of the neck-worn temperature control device. The end of the bracket is the outer end of the second body 12, and the center of the bracket is the inner end of the first body 32 and the second body 12. The second inner case 32a and the first inner case 12a are rotatably connected to form the inner case of the bracket, and the second outer case 34a and the first outer case 12b are rotatably connected to form the outer case of the bracket. Note that the bracket / inner case / outer case of the neck-worn temperature control device may be a non-removable integrated structure.

[0090] In this embodiment, directions such as inward / outward, up / down, front / back, left / right are defined based on the orientation in which the neck-worn temperature control device is worn around the neck of a person. Specifically, the side of the bracket / second body 12 / first body 32 facing the nape of the neck is defined as the inward side, the side facing away from the nape of the neck is defined as the outward side, the side facing the head is defined as the upper side, and the side facing away from the head is defined as the lower side. The length of the bracket / second body 12 / first body 32 refers to the length in the direction around the nape of the neck, the width of the bracket / second body 12 / first body 32 refers to the width in the vertical direction, and the thickness of the bracket / second body 12 / first body 32 refers to the thickness in the inward / outward direction.

[0091] In summary, when the neck-worn temperature control device of the present invention is used for cooling, the low-temperature end of the temperature control sheet is in close contact with the heat conduction member, and the heat conduction member transmits cold and hot air to the neck, especially to the collar, while the fan blows air onto the neck and face. The dual action of the fan's cold air and the temperature control sheet's cold and hot air provides a good heat dissipation and cooling effect. The neck-worn temperature control device of the present invention can also be used for heating. In this case, the direction of the current in the temperature control sheet is changed so that its high-temperature end is in close contact with the heat conduction member, and the heat conduction member conducts heat to the collar to warm it. When heating, the fan may be controlled to turn it off, and the temperature control sheet and heat conduction member may be used for heating. Alternatively, in other embodiments, a heat-generating element such as a resistance wire or an electric heating sheet may be installed in the airflow path of the fan, so that the final airflow is warm air. As a result, the dual action of the fan's warm air and the heat of the temperature control sheet provides a good heating effect.
