[0019] In the following description, for purposes of explanation and not limitation, specific details are provided, such as particular system structures and techniques, to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be practiced in other embodiments without these specific details. In other circumstances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0020] 1 to 6, a portable temperature adjusting device according to a first embodiment of the present application defines a wearing space 10. The portable temperature adjusting device includes a main body 11, a protruding portion 12 provided on the main body 11, and a temperature conducting member 2 provided at least partially on the protruding portion 12 for contacting the human body. The main body 11 includes a first side 111, and the protruding portion 12 is provided on the first side 111 and extends and protrudes in a direction away from the first side 111.

[0021] Specifically, the portable temperature control device is a neck-worn temperature control device, and the main body 11 has a U-shaped structure with a free end or a closed circular structure without a free end. The main body 11 may define the wearing space 10 by itself, or the main body 11 may define the wearing space 10 together with the protruding portion 12. The wearing space 10 can be worn on a part of the human body, such as the neck. The temperature conducting member 2 is provided on the surface of the protruding portion 12 and faces the wearing space 10. The temperature conducting member 2 is preferably made of a material with high thermal conductivity, such as a metal material such as aluminum. When the portable temperature control device is worn on the neck of a human body via the wearing space 10, the first side 111 of the main body 11 contacts the shoulder of the human body as a support surface. The protruding portion 12 is provided on the first side 111 and protrudes away from the first side 111. In this case, the protruding portion 12 can extend into the collar, and the temperature conducting member 2 contacts the back region of the human body.

[0022] This portable temperature adjustment device can extend toward the collar covering the back of the human body by the protrusion 12, and can even extend into the collar and contact the back of the human body through the temperature conduction member 2 provided on the protrusion 12. Therefore, by conducting cold or hot air to the back of the human body through the temperature conduction member 2, it can also adjust the temperature of the back area covered by the collar, meeting the adjustment needs of cooling the back of the human body with a cold compress or massaging it with a hot compress, and improving the user's usage experience.

[0023] The temperature conduction member 2 includes a first portion 21 provided on the surface of the protrusion 12 facing the mounting space 10, and the first portion 21 extends to the side of the protrusion 12 away from the main body 11, thereby enabling temperature conduction even when the side of the protrusion 12 away from the main body 11 comes into contact with the human body.

[0024] A rear exhaust port 122 is provided on the side of the protrusion 12 away from the main body 11, and the first part 21 is positioned to avoid the rear exhaust port 122, or a through hole corresponding to the rear exhaust port 122 is provided in the first part 21.

[0025] In this embodiment, when the temperature conducting member 2 is used to conduct cool air to the back of the human body, in order to enhance the cooling effect on the back of the human body, the back exhaust port 122 may be provided on the side of the protruding portion 12 away from the main body portion 11, and the first portion 21 may be positioned to avoid the back exhaust port 122, or a through-hole corresponding to the back exhaust port 122 may be provided in the first portion 21. The first portion 21 and the back exhaust port 122 operate independently, and the first portion 21 can blow air toward the back of the human body through the back exhaust port 122 without interfering with each other or obstructing the exhaust from the back exhaust port 122, thereby achieving a cooling effect.

[0026] The temperature conduction member 2 includes a second portion 22 provided on the surface of the main body 11 facing the mounting space 10, and the first portion 21 and the second portion 22 are either separate or integral. Specifically, when the first portion 21 and the second portion 22 are separate, they are two separate components, whereas when the first portion 21 and the second portion 22 are integral, they are one component. This allows heat to be conducted to the neck via the second portion 22 of the temperature conduction member 2, and the protrusion 12 extends to the collar, allowing heat to be conducted to the back of the human body via the first portion 21 of the temperature conduction member 2. This increases the area over which temperature is conducted to the human body, allowing for temperature regulation over a wider range.

[0027] When the first part 21 and the second part 22 are integrated, the first part 21 smoothly transitions into the second part 22, specifically, the surface of the first part 21 is flush with the surface of the second part 22, making the portable temperature regulating device more ergonomic. When the back of the human body contacts the first part 21 and the neck of the human body contacts the second part 22, the contact feeling of the human body temperature conducting member 2 becomes more comfortable.

[0028] The main body 11 includes a second side 112 opposite the first side 111 , and the second portion 22 extends to the second side 112 .

[0029] The main body 11 includes a base 110 and arm portions 13 provided at both ends of the base 110. The base 110 and the two arm portions 13 together define the mounting space 10. The temperature conduction member 2 includes a third portion 23 provided on the surface of the arm portion 13 facing the mounting space 10. In this embodiment, there are two third portions 23, each disposed on one of the two arm portions 13. The second portion 22 contacts the back side of the neck of the human body, and the two third portions 23 contact the left and right sides of the neck of the human body, respectively. The second portion 22 and the third portion 23 may be separate or integral. Specifically, when the second portion 22 and the third portion 23 are separate, they are two separate parts. When the second portion 22 and the third portion 23 are integral, they are one integrally molded part. This allows the temperature to be conducted by contacting the side of the neck of the human body through the third part 23 of the temperature conducting member 2, and furthermore, the area over which the temperature is conducted to the human body is widened, thereby realizing a wider range of temperature adjustment.

[0030] The base 110 includes a second side 112 opposite the first side 111, and the arm 13 includes a third side 131 and a fourth side 132. The third side 131 is on the same side as the first side 111, the fourth side 132 is on the same side as the second side 112, and the third portion 23 extends to the third side 131 and / or the fourth side 132.

[0031] In this embodiment, by positioning the third part 23 so that it extends to the third side 131 and / or the fourth side 132, on the one hand, the contact area with the neck of the human body can be significantly increased, and on the other hand, after the human body wears the portable temperature adjustment device of the present application, when the human body moves its head, for example, by turning its head angle, the third part 23 can always maintain contact with the neck of the human body, thereby improving the experience of temperature conduction from the temperature conduction member 2 to the human body.

[0032] The outer contour of the protrusion 12 away from the main body 11 has an arc-shaped structure. In this way, the shape of the protrusion 12 is ergonomic, and by having a smooth, rounded outer shape, even if the protrusion 12 comes into contact with or collides with the human body when worn, it is comfortable and less likely to cause scratches or punctures. Furthermore, compared to a linear structure, the arc-shaped structure can reduce the contact area when the user comes into contact with the side of the protrusion 12 away from the main body 11, further improving wearing comfort.

[0033] The arc-shaped structure has an inclined surface 123 that is inclined from the side away from the mounting space 10 to the side closer to the mounting space 10. The role of the inclined surface 123 is to prevent the end of the protrusion 12 from hitting the back of the human body when the user raises their head, causing discomfort to the user. Therefore, by providing the inclined surface 123, the shape of the protrusion 12 is more ergonomic, the outer shape is smoother and more rounded, and the wearing comfort can be improved.

[0034] The portable temperature regulating device includes a temperature regulating member 4 provided on the main body 11, arm 13, and / or protrusion 12 and used for cooling and / or heating. The temperature conducting member 2 is in thermally conductive contact with the temperature regulating member 4 and conducts the temperature of the temperature regulating member 4 to the human body. Specifically, the temperature regulating member 4 may be a semiconductor cooling sheet, and when current is applied, its opposing sides form a cold end and a hot end, respectively, and the cold end and the hot end can be switched alternately by switching the direction of the current, and the temperature conducting member 2 conducts cold or heat to the human body.

[0035] The portable temperature adjusting device includes a blower 3 provided in the main body 11 or the protruding portion 12, and a heat dissipation member 5 provided in the main body 11 or the protruding portion 12. One end of the temperature adjusting member 4 is in thermal conductive contact with the heat dissipation member 5, and the other end of the temperature adjusting member 4 is in thermal conductive contact with the temperature conducting member 2. A heat dissipation port 14 is provided on the side of the main body 11 or the protruding portion 12 opposite the mounting space 10. The air from the blower 3 exchanges heat through the heat dissipation member 5 and then blows out through the heat dissipation port 14, thereby achieving heat dissipation. In the embodiment of FIG. 4 , the blower 3 and the temperature adjusting member 4 are provided in the main body 11, and a heat dissipation port 14 is provided on the side of the main body 11 away from the mounting space 10, at a position corresponding to the heat dissipation member 5. The air from the blower exchanges heat through the heat dissipation member 5 and then blows out through the heat dissipation port 14, thereby achieving heat dissipation. It should be emphasized that the heat dissipation member 5 and the blower 3 must cooperate to dissipate heat to the hot end of the temperature adjustment member 4 only when the temperature conduction member 2 conducts cold air.

[0036] Referring to FIGS. 7 to 12, the portable temperature regulator of the second embodiment of the present application is basically the same as the portable temperature regulator of the first embodiment. In this embodiment, the extension distance of the protrusion 12 (see D in FIG. 7) exceeds 15 mm, so that the air can be blown out from the first exhaust port 122 on the opposite side of the second side 112 of the protrusion toward the back of the human body, meeting the cooling regulation needs of the back of the human body and improving the cooling experience of the user.

[0037] Furthermore, the extension distance of the protrusion 12 is 20 mm to 50 mm, for example, 20 mm, 30 mm, 40 mm, or 50 mm. This extension distance allows the protrusion 12 to extend more effectively into the collar, allowing air to be blown onto the back to cool it, without affecting the activity of the user wearing the portable temperature control device. For example, after the user wears the portable temperature control device around their neck via the wearing space 10, the protrusion 12 does not prevent the user from tilting their head back.

[0038] More preferably, the extension distance of the protrusion 12 is 30 mm to 40 mm, for example, 30 mm, 33 mm, 36 mm, or 40 mm. This extension distance allows the protrusion 12 to extend more effectively into the collar, allowing air to be blown onto the back to cool it, and the extension distance becomes more appropriate, resulting in a more comfortable fit for the user.

[0039] The outer contour opposite the second side 112 of the protrusion 12 is an arc-shaped structure.

[0040] In this embodiment, since the opposite side of the second side 112 of the protrusion 12 comes into contact with the user's back during use of the portable temperature adjusting device, the opposite side of the second side 112 of the protrusion 12 is configured in an arc-shaped structure, making the outer shape smoother and more rounded, and conforming to ergonomic design. On the one hand, when the user touches the opposite side of the second side 112 of the protrusion 12, the tactile sensation is more comfortable, and no scratching or pricking sensation occurs, improving wearing comfort. On the other hand, compared to a linear structure, the arc-shaped structure reduces the contact area when the user touches the opposite side of the second side 112 of the protrusion 12, further improving wearing comfort.

[0041] Furthermore, the arc-shaped structure includes a first inclined wall 121 and a second inclined wall 125. The first inclined wall 121 and the second inclined wall 125 are connected to each other, and the distance between them gradually decreases in a direction away from the second side.

[0042] In this embodiment, one end of the first inclined wall 121 is connected to the first side 111, the other end of the first inclined wall 121 is connected to one end of the second inclined wall 125, and the other end of the second inclined wall 125 is also connected to the first side 111. At the same time, the first inclined wall 121 and the second inclined wall 125 are connected to each other, and the distance between them gradually decreases in a direction away from the second side 112, so that the first inclined wall 121 and the second inclined wall 125 together form a "V"-shaped structure. Compared to a linear structure, this arrangement can reduce the contact area when a user touches the side opposite the second side 112 of the protrusion 12, further improving wearing comfort.

[0043] Furthermore, a first exhaust port 122 is disposed in the first inclined wall 121 and the second inclined wall 125 .

[0044] In this embodiment, the first inclined wall 121 and the second inclined wall 125 are both provided with first exhaust ports 122. One end of the first exhaust port 122 is located on the first inclined wall 121, and the other end is located on the second inclined wall 125, so the first exhaust port 122 also has a "V" shape. This arrangement allows the exhaust from the first exhaust port 122 to exhibit diffused exhaust, increasing the exhaust area of ​​the first exhaust port 122 and increasing the exhaust area relative to the back of the human body. Of course, the number of first exhaust ports 122 may be two. One first exhaust port 122 is located on the first inclined wall 121, and the other first exhaust port 122 is located on the second inclined wall 125.

[0045] Furthermore, the arc-shaped structure has an inclined surface 123, and the first exhaust port 122 is provided on the inclined surface 123, which is inclined from the side away from the wearing space 10 to the side closer to the wearing space 10. By providing the first exhaust port 122 on the inclined surface 123, when the user touches the side opposite the second side 112 of the protrusion 12, it is possible to prevent the skin on the user's back from blocking the first exhaust port 122 and hindering exhaust from the first exhaust port 122, thereby improving the reliability of exhaust. The role of the inclined surface 123 is to prevent the end of the protrusion 12 from hitting the back of the human body when the user raises their head, causing discomfort to the user. Therefore, by providing the inclined surface 123, the shape of the protrusion 12 is more ergonomic, with a smoother and more rounded outer shape, which improves wearing comfort.

[0046] Furthermore, the first air outlet 122 is disposed on the side of the inclined surface 123 that is closer to the mounting space 10. By locating the first air outlet 122 in this position, the air blown out from the first air outlet 122 can be conducted along the back surface of the human body, thereby further improving the cooling effect of the present application.

[0047] The main body 11 includes a base 110 and two arms 13 provided at both ends of the base 110. The base 110 and the two arms 13 together define the mounting space 10, and the base 110 and the protrusion 12 are integrally molded.

[0048] In this embodiment, the base 110 and the protrusion 12 may be an integrally molded structure. The integrally molded structure can reduce the assembly and positioning steps between the base 110 and the protrusion 12, which helps to improve the manufacturing yield and reduce the manufacturing cost of the portable temperature adjustment device of the present application.

[0049] Furthermore, the main body 11 includes a main body outer wall 116 facing away from the mounting space 10 in the thickness direction, and the protrusion 12 includes a protrusion outer wall 124 facing away from the mounting space 10 in the thickness direction, with the main body outer wall 116 smoothly transitioning into the protrusion outer wall 124. During use of this neck-worn temperature control device, the protrusion 12 extends into the collar to blow air onto the back of the body, thereby achieving temperature control on the back. Because the main body outer wall 116 smoothly transitions into the protrusion outer wall 124, the protrusion 12 easily and smoothly extends into the collar to blow air onto the back of the body without being obstructed by the shapes of the main body outer wall 116 and the protrusion outer wall 124. At the same time, the collar rises less, is not too noticeable, and provides good concealment. Since the main body outer wall 116 and the protrusion outer wall 124 are flush with each other, the protrusion 12 can extend into the collar as easily and smoothly as possible, and at the same time, the rise of the collar is as small as possible, is not noticeable, and has good concealment properties.

[0050] The main body 11 includes a main body inner wall 117 that faces the mounting space 10 in the thickness direction, and the protruding portion 12 includes a protruding portion inner wall 126 that faces the mounting space 10 in the thickness direction, with the main body inner wall 117 smoothly transitioning to the protruding portion inner wall 126. As a result, when the neck-worn temperature regulator is worn around the neck, the sensation of the neck coming into contact with the main body inner wall 117 and the protruding portion inner wall 126 is comfortable.

[0051] An air inlet 15 is provided on the opposite side of the mounting space 10 of the main body 11 or the protruding portion 12 for air to enter the portable temperature control device. A fan is further provided on the main body 11 or the protruding portion 12. The fan is disposed corresponding to the air inlet 15 and the first exhaust port 122. The fan is used to accelerate the airflow at the air inlet 15, guide it to the first exhaust port 122, and guide it to the outside from the first exhaust port 122.

[0052] Furthermore, a second exhaust port 113 for blowing out air is provided on the second side 112 of the main body 11.

[0053] In this embodiment, the second side 112 of the main body 11 is provided with a second exhaust port 113 for blowing out air. The second exhaust port 113 can blow out air toward the neck or head. When the portable temperature adjusting device is worn around the neck, the protrusion 12 extends to the back of the human body, so that the first exhaust port 122 can accurately blow out air toward the back of the user for cooling, and at the same time, the second exhaust port 113 can blow out air toward the user's neck for cooling. That is, the portable temperature adjusting device can effectively blow out air toward the back of the human body and also toward the neck of the human body. This improves the practicality of the portable temperature adjusting device and also provides a better user experience.

[0054] As shown in FIGS. 13 to 18 , the central portion of the main body 11 and the protruding portion 12 together form the middle portion of the portable temperature adjusting device. A first air duct 210 and a second air duct 310 are provided inside the middle portion, with the first air duct 210 communicating with the first exhaust port 122 and the second air duct 310 communicating with the second exhaust port 113. The first air duct 210 can independently blow air to the first exhaust port 122, and the second air duct 310 can independently blow air to the second exhaust port 113, thereby optimizing the internal air-blowing structure of the portable temperature adjusting device. The independent air-blowing structure of the first air duct 210 and the second air duct 310 ensures that the airflow that forms the wind is rectified and then smoothly blows out to the outside through the first exhaust port 122 and the second exhaust port 113.

[0055] The portable temperature control device further includes a first air guide member 41. The first air guide member 41 is disposed inside the middle section, and the first air guide member 41 and the inner wall of the middle section form a first air duct 210. In order to reduce the difficulty of manufacturing the first air duct 210 during the manufacturing process, the first air guide member 41 can be fixed to the inside of the middle section by a mounting method. In another embodiment, the first air guide member 41 and the inner wall of the middle section are integrally formed, and the first air guide member 41 and the inner wall of the middle section form the air duct, and then perform a guiding function on the airflow.

[0056] Furthermore, the first air guide member 41 includes an air guide plate 411 and a protective plate 412 arranged to form an included angle with each other. The air guide plate 411 is connected to the protective plate 412, and the air guide plate 411 is hermetically connected to a wall of the protrusion 12 opposite the second exhaust port 113, and the protective plate 412 is hermetically connected to a side wall of the protrusion 12 facing the installation space 10, thereby preventing air leakage between both ends of the first air duct 210 and effectively guiding the airflow to the first exhaust port 122. Specifically, one end of the air guide plate 411 remote from the first exhaust port 122 flares outward to form a trumpet-shaped inlet, so that the airflow entering through the inlet is compressed by the first air duct 210 at the end remote from the inlet, and the airflow is further concentrated as it flows toward the first exhaust port 122, thereby making the airflow flowing out of the first exhaust port 122 stronger.

[0057] Furthermore, the opposite side of the air guide plate 411 to the first air duct 210 and the opposite side of the protective plate 412 to the first air duct 210, together with the side walls of the middle part, form an accommodating cavity for mounting a circuit board, thereby preventing the circuit board from interfering with the air flow through the first air duct.

[0058] In this embodiment, an air intake port 15 is provided in the middle portion, and a partition member 33 is provided inside the first air duct 210. The partition member 33 divides the first air duct 210 into a first sub-air duct and a second sub-air duct, with one end of the first sub-air duct and one end of the second sub-air duct both communicating with the air intake port 15, and the other end of the first sub-air duct and the other end of the second sub-air duct both communicating with the first exhaust port 122. The first exhaust port 122 has a flat and elongated shape, and in order to make the overall exhaust from the first exhaust port 122 relatively uniform, the partition member 33 correspondingly divides the first air duct 210 into the first sub-air duct and the second sub-air duct, so that when the airflow is finally blown out from the first exhaust port 122, the volume of the blown air at each position of the first exhaust port 122 is relatively uniform.

[0059] In this embodiment, the portable temperature control device includes a second air guide member 42. The second air guide member 42 is disposed within the middle section. The second air guide member 42 includes a bottom plate 43, a first side plate 44, and a second side plate 45. The first side plate 44 and the second side plate 45 are respectively connected to both sides of the bottom plate 43, and the first side plate 44 and the second side plate 45 are disposed in a "V" shape. The bottom plate 43, the first side plate 44, and the second side plate 45 form the second air duct 310 together with the inner wall of the middle section. To reduce the difficulty of manufacturing the second air duct 310 during the manufacturing process, this can be achieved by fixing the second air guide member 42 to the inside of the middle section using a mounting method. In another embodiment, the second air guide member 42 is integrally formed with the inner wall of the middle section, and the second air guide member 42 and the inner wall of the middle section function to guide the airflow after forming the air duct.

[0060] As shown in FIGS. 13 to 17 , the third embodiment of the present application differs from the second embodiment in that, in this embodiment, an air intake 15 is provided in the intermediate portion, and the air intake 15 includes a first air intake 151 and a second air intake 152. A first volute casing 51, a second volute casing 52, a first blower 53, and a second blower 54 are provided inside the intermediate portion. The first volute casing 51 is surrounded by a first mounting cavity 25 that communicates with the first air intake 151. The first volute casing 51 is provided with a first opening 26 that communicates with the first mounting cavity 25, and the first opening 26 communicates with a first air duct 210. The first blower 53 is disposed within the first mounting cavity 25. The second volute casing 52 is surrounded by a second mounting cavity 27 that communicates with the second air intake 152. The second volute casing 52 has a second opening 28 that communicates with the second mounting cavity 27, and the second opening 28 communicates with the second air duct 310. The second blower 54 is disposed in the second mounting cavity 27. The first volute casing 51 and the second volute casing 52 separate the first blower 53 and the second blower 54, thereby preventing the first blower 53 and the second blower 54 from interfering with each other during operation.

[0061] When the first fan 53 is operated, the first fan 53 draws in air through the first air intake port 151 and converts it into an airflow within the first mounting cavity 25. The airflow passes through the first air duct 210 and is blown out through the first air outlet 122, allowing the user to feel cool. Similarly, when the second fan 54 is operated, the second fan 54 draws in air through the second air intake port 152 and converts it into an airflow within the second mounting cavity 27. The airflow passes through the second air duct 310 and is blown out through the second air outlet 113, allowing the user to feel cool. Even if the first air intake port 151 is blocked by a foreign object, the second air intake port 152 can normally supply air to the second mounting cavity 27, and the portable temperature control device can blow air out through the second air outlet 113. Similarly, even if second air inlet 152 is blocked by a foreign object, first air inlet 151 can still normally supply air to first mounting cavity 25, and the portable temperature regulator can blow air out through first air outlet 122. That is, first mounting cavity 25 uses first air inlet 151 alone to take in air, and second mounting cavity 27 uses second air inlet 152 alone to take in air, thereby ensuring that at least one of first air outlet 122 and second air outlet 113 of the portable temperature regulator operates normally.

[0062] As shown in FIGS. 14 to 18 , the portable temperature adjusting device further includes a heat dissipation member 5, a temperature conduction member 2, and a temperature adjusting member 4. A heat dissipation air duct 71 is provided inside the middle section, and the heat dissipation air duct 71 is located between the first air duct 210 and the second air duct 310. The heat dissipation member 5 is disposed inside the heat dissipation air duct 71. A heat dissipation port 14 is provided on the opposite side of the middle section from the mounting space 10, communicating with the heat dissipation air duct 71. The temperature conduction member 2 is fixed to the side of the middle section facing the mounting space 10. The temperature adjusting member 4 is thermally connected to the heat dissipation member 5 and the temperature conduction member 2. The temperature adjusting member 4 is a semiconductor cooling sheet. When the temperature adjusting member 4 cools the temperature conduction member 2, the temperature adjusting member 4 generates a large amount of hot air. This hot air is transferred to the heat dissipation member 5, which then dissipates the hot air to the outside of the portable temperature adjusting device through the heat dissipation port 14. When the portable temperature control device is worn around the neck, it can not only blow air onto the human body for cooling through the first exhaust port 122 and the second exhaust port 113, but also adhere to the neck through the temperature conduction member 2 and transmit cool air to the neck for cooling, so that the portable temperature control device has multiple functions for cooling the human body and further improves the practicality of the portable temperature control device.

[0063] In this embodiment, the heat dissipation vent 14 includes a first heat dissipation vent 141 and a second heat dissipation vent 142. The heat dissipation member 5 divides the heat dissipation air duct 71 into a first heat dissipation air duct and a second heat dissipation air duct. One end of the first heat dissipation air duct communicates with the first opening 26, and the other end of the first heat dissipation air duct communicates with the first heat dissipation vent 141. One end of the second heat dissipation air duct communicates with the second opening 28, and the other end of the second heat dissipation air duct communicates with the second heat dissipation vent 142. The direction in which the airflow flows through the first heat dissipation air duct is opposite to the direction in which the airflow flows through the second heat dissipation air duct. Specifically, the first heat dissipation air duct and the first air duct 210 separate the airflow blown out from the first opening 26 into two flows. One airflow passes through the first air duct 210 and is blown out to the first exhaust port 122, where it is used to blow air onto the back of the human body and dissipate heat. The other airflow passes through the first heat dissipation air duct and is blown out to the first heat dissipation port 141. The airflow flows through the first heat dissipation air duct, carrying the hot air released from the heat dissipation member 5 and being blown out to the first heat dissipation port 141, thereby dissipating heat from and cooling the heat dissipation member 5. The second heat dissipation air duct and the second air duct 310 separate the airflow blown out from the second opening 28 into two flows. One airflow passes through the second air duct 310 and is blown out to the second exhaust port 113, where it is used to blow air onto the neck of the human body and dissipate heat. The other airflow passes through the second heat dissipation air duct and is blown out to the second heat dissipation port 142. The airflow flows through the second heat dissipation air duct, carries the hot air released from the heat dissipation member 5, and is blown out through the second heat dissipation port 142, so that the heat dissipation member 5 can be cooled by dissipating heat therefrom.

[0064] In this embodiment, the heat dissipation member 5 includes a first heat dissipation fin 511 and a second heat dissipation fin 512. There are multiple first heat dissipation fins 511 and multiple second heat dissipation fins 512. A first heat dissipation gap 73 is formed between two adjacent first heat dissipation fins 511, and one end of the first heat dissipation gap 73 remote from the first opening 26 communicates with the first heat dissipation outlet 141. A second heat dissipation gap 74 is formed between adjacent second heat dissipation fins 512, and one end of the second heat dissipation gap 74 remote from the second opening 28 communicates with the second heat dissipation outlet 142. The portion of the first heat dissipation gap 73 through which air enters and the portion of the second heat dissipation gap 74 through which air enter are arranged opposite each other. The first heat dissipation gap 73 guides the airflow blown out from the first opening 26 to the first heat dissipation port 141 and blows it out, and the second heat dissipation gap 74 guides the airflow blown out from the second opening 28 to the second heat dissipation port 142 and blows it out. The direction in which the airflow blown out from the first opening 26 flows through the first heat dissipation gap 73 is opposite to the direction in which the airflow blown out from the second opening 28 flows through the second heat dissipation gap 74. The multiple first heat dissipation fins 511 and the multiple first heat dissipation gaps 73, the multiple second heat dissipation fins 512 and the multiple second heat dissipation gaps 74 increase the overall area of ​​the heat dissipation member 5 that comes into contact with the heat dissipation airflow, improving the heat dissipation capacity of the heat dissipation member 5.

[0065] 19 and 20 show a fourth embodiment of the present application. Compared with the second embodiment, in this embodiment, the second air outlet 113 includes a first sub-air outlet 1131 and a second sub-air outlet 1132 arranged side by side, with the first sub-air outlet 1131 being closer to the installation space than the second sub-air outlet 1132. The portable temperature control device includes a second air guide member 42, which is arranged inside the middle portion. The air guide member 42 includes a first partition plate 46 and a second partition plate 47 connected to each other, and the first partition plate 46 and the second partition plate 47 are integrally formed. The second partition plate 47 is installed at an angle to the first partition plate 46, is connected between both sides of the first partition plate 46, and is arranged across both ends of the first partition plate 46. The first partition plate 46 and the inner wall of the middle portion form the second air duct 310. The second partition plate 47 is located within the second air duct 310 and divides the second air duct 310 into a third sub-air duct and a fourth sub-air duct. The third sub-air duct communicates with the first sub-exhaust port 1131, and the fourth sub-air duct communicates with the second sub-exhaust port 1132. Since the third sub-air duct and the fourth sub-air duct do not interfere with each other when directing air, it is possible to ensure that the volume of air blown out from the first sub-exhaust port 1131 and the second sub-exhaust port 1132 is uniform. The structure of other parts of this embodiment is the same as that of the second embodiment described above.

[0066] 21 to 28, a fifth embodiment of the present application provides a portable temperature adjusting device. Compared to the first embodiment, in this embodiment, the portable temperature adjusting device includes a main body 11. The main body 11 includes two casings 107 connected to each other, each of which includes a first fan 200 and a second fan 300. The casing 107 is provided with a first exhaust port 101, a bypass 102, and a second exhaust port 103, arranged in this order along its length. The first fan 200 and the second fan 300 are located between the first exhaust port 101 and the second exhaust port 103, and are located within the bypass 102. The first fan 200 is used to blow air to the first exhaust port 101, and the second fan 300 is used to blow air to the second exhaust port 103.

[0067] In this embodiment, both ends of the main body 11 are curved to surround the mounting space 10 for mounting, and an opening communicating with the mounting space 10 is formed between the two ends of the main body 11. The main body 11 may be formed by joining two casings 107 together, or may be artificially divided into two casings 107.

[0068] Furthermore, the main body 11 has a first end 105 and a second end 106. The length from the avoidance portion 102 to the first end 105 is shorter than the length from the avoidance portion 102 to the second end 106, and the length from the avoidance portion 102 to the first end 105 is longer than the length from the avoidance portion 102 to the center of the main body 11.

[0069] In this embodiment, the avoidance portion 102 is positioned corresponding to one of the user's ears, the first end 105 is located on one casing 107, the second end 106 is located on the other casing 107, and the second exhaust port 103 is located in the center of the main body 11. Because the avoidance portion 102 is located on one casing 107, the length from the avoidance portion 102 to the first end 105 is shorter than the length from the avoidance portion 102 to the second end 106. Furthermore, because the position of the user's ear is closer to the back of the head than to the face, the length from the avoidance portion 102 to the first end 105 is longer than the length from the avoidance portion 102 to the center of the main body 11, and therefore the avoidance portion 102 can be positioned directly below the ear when the user wears this portable temperature adjustment device.

[0070] In one embodiment, a first exhaust path 104 and a second exhaust path 108 are provided within the casing 107. The first exhaust path 104 is located on a side of the first fan 200 away from the center of the avoidance portion 102. One end of the first exhaust path 104 is connected to the inlet of the first fan 200, and the first fan 200 blows out air through the inlet. The other end extends in a direction away from the first fan 200 and is connected to the first exhaust port 101. The second exhaust path 108 is located on a side of the second fan 300 away from the center of the avoidance portion 102. One end of the second exhaust path 108 is connected to the inlet of the second fan 300, and the other end extends in a direction away from the second fan 300 and is connected to the second exhaust port 103.

[0071] In the present application, the central portion of the avoidance portion 102 refers to the portion of the avoidance portion 102 located between the first fan 200 and the second fan 300.

[0072] The cross-sectional area of ​​the first exhaust passage 104 gradually decreases from one end closer to the first fan 200 to the other end farther from the first fan 200. Because the volume of air in the first exhaust passage 104 gradually decreases as it is blown out from the first exhaust port 101, the exhaust speed at the end closer to the first fan 200 of the first exhaust port 101 is faster than the exhaust speed at the end farther from the first fan 200. By narrowing the first exhaust passage 104, the exhaust speed at the end farther from the first fan 200 of the first exhaust port 101 can be increased, making the overall exhaust from the first exhaust port 101 more uniform.

[0073] Furthermore, the first exhaust path 104 includes a first sub-air duct 1041. A third exhaust port 109 communicating with the first exhaust port 101 is provided at one end of the first sub-air duct 1041 close to the first exhaust port 101. The length direction of the third exhaust port 109 is the same as the length direction of the first exhaust port 101.

[0074] Further, a flow guide member 140 is provided within the casing 107. The flow guide member 140 is located on a side away from the center of the avoidance portion 102 of the first fan 200. At least a portion of the first exhaust path 104 is disposed within the flow guide member 140. The flow guide member 140 includes a flow guide plate 143, which is partially bent to surround and form a first sub-air duct 1041.

[0075] Furthermore, flow guide member 140 includes a base 144 and a flow guide plate 143 provided at one end of base 144. Flow guide plate 143 includes a bent portion 1431, and a first flow guide portion 1432 and a second flow guide portion 1433 provided on the same side as bent portion 1431. First flow guide portion 1432 and second flow guide portion 1433 extend along the length of base 144.

[0076] Furthermore, the first exhaust path 104 includes a second sub-air duct 1042 and a third sub-air duct 1043. The first sub-air duct 1041 and the second sub-air duct 1042 are arranged side by side at the same end of the third sub-air duct 1043, and the second sub-air duct 1042 is connected to the third sub-air duct 1043.

[0077] Specifically, the extension direction of the first sub-air duct 1041 is approximately the same as the extension direction of the second sub-air duct 1042 and the extension direction of the third sub-air duct 1043, and the width of the first sub-air duct 1041 and the width of the second sub-air duct 1042 are both smaller than the width of the third sub-air duct 1043.

[0078] In one embodiment, the portable temperature adjustment device further includes a temperature conducting member 2 provided in the casing 107. The temperature conducting member 2 is at least partially disposed in the avoidance portion 102. Because the first exhaust port 101 and the second exhaust port 103 cannot directly adjust the temperature of the air blown out of the avoidance portion 102, the arrangement of the temperature conducting member 2 allows for contact temperature adjustment of the user's area close to the avoidance portion 102.

[0079] Furthermore, a temperature adjustment member 4 and a heat dissipation member 5 are further provided inside the casing 107. The temperature conduction member 2 and the heat dissipation member 5 are respectively arranged on opposite sides of the temperature adjustment member 4 and are connected to the temperature adjustment member 4 via thermal conduction.

[0080] In this embodiment, the temperature adjustment member 4 is a semiconductor cooler, and the temperature conduction member 2 is made of an aluminum alloy. The temperature conduction member 2 is located on the side of the inner case 170 that is closer to the mounting space 10. The temperature conduction member 2 is used to evenly transfer the cool or hot air generated by the semiconductor cooler to the user's neck, thereby achieving a cooling or heating function. The heat dissipation member 5 includes a plurality of heat dissipation fins to increase the contact area between the airflow blown out from the first fan 200 and the heat dissipation member 5 and improve heat dissipation efficiency.

[0081] In one embodiment, the casing 107 is further provided with a heat dissipation port 118. The heat dissipation port 118 is located on a side of the first fan 200 away from the center of the avoidance portion 102. A heat dissipation air duct 119 is provided within the casing 107. The heat dissipation air duct 119 is located on a side of the first fan 200 away from the second fan 300. One end of the heat dissipation air duct 119 communicates with the air guide port of the first fan 200, and the other end extends in a direction away from the first fan 200 and communicates with the heat dissipation port 118. The heat dissipation member 5 is disposed within the heat dissipation air duct 119.

[0082] Specifically, the outer case 160 is provided with a first air intake port 114, a second air intake port 115, and a heat dissipation port 118. The first air intake port 114 is disposed corresponding to the first fan 200, the second air intake port 115 is disposed corresponding to the second fan 300, and the first exhaust port 101 is disposed at the boundary between the outer case 160 and the inner case 170. The casing 107 is provided with a storage cavity 133 communicating with the first exhaust port 101. The first fan 200 is located within the storage cavity 133. A flow guide member 140 is further provided within the storage cavity 133. The first fan 200 is located between the flow guide member 140 and the second fan 300. The air guide member 140 separates a part of the receiving cavity 133 to form a heat dissipation air duct 119 .

[0083] Further, a control circuit board 180 and a power supply 190 are provided within the receiving cavity 133, and the control circuit board 180 is electrically connected to the power supply 190, the temperature adjusting member 4, the first fan 200, and the second fan 300. The control circuit board 180 is used to control the start and stop of each fan, the operating tap position, the operating mode (cooling or heating) and operating temperature of the temperature adjusting member 4, etc., according to commands input by the user.

[0084] In one embodiment, the main body 11 includes an upper side and a lower side arranged opposite each other, and the two second exhaust ports 103 are both located on the upper side of the main body 11, or the two second exhaust ports 103 are both located on the lower side of the main body 11, or one second exhaust port 103 is located on the upper side of the main body 11 and the other second exhaust port 103 is located on the lower side of the main body 11.

[0085] In this embodiment, both first exhaust ports 101 are located on the upper side of the main body 11, one second exhaust port 103 is located on the upper side of the main body 11, and the other second exhaust port 103 is located on the lower side of the main body 11. When a user wears the portable temperature control device around their neck, the upper side of the main body 11 faces the user's head and facilitates blowing air onto the user's face and back of the neck for cooling, and the lower side of the main body 11 faces the user's body and facilitates blowing air onto the user's back for cooling. The avoidance portions 102 face the user's ears and prevent airflow from being blown directly towards the ears when air is blown out from the first exhaust port 101 and the second exhaust port 103, thereby reducing noise heard by the user.

[0086] In one embodiment, the avoidance portion 102 is provided with a flexible connecting member 1021 .

[0087] Specifically, the main body 11 includes an outer case 160 and an inner case 170 connected to each other, with the inner case 170 being closer to the mounting space 10 than the outer case 160. The outer case 160 is a long, one-piece, plate-like structure, and the inner case 170 includes a first case section 171, a second case section 172, and a third case section 173 arranged at intervals along the length of the outer case 160. A flexible connecting member 1021 is provided between the first case section 171 and the second case section 172, and another flexible connecting member 1021 is provided between the second case section 172 and the third case section 173. The flexible connecting member 1021 may be made of soft rubber. The provision of the flexible connecting member 1021 improves the deformation ability of the main body 11, making it easier to adjust the size of the mounting space 10 and adapting it to various users.

[0088] The portable temperature regulating device provided in the present application includes a main body 11. The main body 11 includes two casings 107 connected to each other, each of which is provided with a first fan 200 and a second fan 300. The casing 107 is provided with a first exhaust port 101, a bypass section 102, and a second exhaust port 103 in that order in the longitudinal direction. The first fan 200 and the second fan 300 are located between the first exhaust port 101 and the second exhaust port 103, and the first fan 200 and the second fan 300 are located within the bypass section 102. When this portable temperature control device is worn around the neck of a user, the first fan 200 moves the airflow away from the center of the avoidance portion 102 and blows it out through the first exhaust port 101, and the second fan 300 moves the airflow away from the center of the avoidance portion 102 and blows it out through the second exhaust port 103. Because the avoidance portion 102 corresponds to the position of the user's ears, on the one hand, the first exhaust port 101 and the second exhaust port 103 do not blow air directly at the user's ears, thereby reducing noise received by the ears, and on the other hand, the airflows generated by the first fan 200 and the second fan 300 are blown out in a direction away from the avoidance portion 102, making it less likely for noise to enter the user's ears, further reducing noise received by the ears and improving the user's usage experience.

[0089] In addition, as the airflow generated by the fan passes through the air duct and flows to the exhaust port, friction between the airflow and the air duct wall occurs, generating noise, and the noise overlaps along the direction of airflow movement and reaches its maximum at the exhaust port. When the portable temperature control device is worn around the user's neck, the avoidance portion 102 is the area of ​​the main body 11 closest to the user's ears. Therefore, by arranging the first fan 200 and the second fan 300 on opposite sides of the avoidance portion 102 and blowing air away from the center of the avoidance portion 102, the noise can overlap in a direction away from the user's ears, thereby reducing the noise that reaches the user's ears.

[0090] 29 to 43, a sixth embodiment of the present application provides a portable temperature adjusting device. Compared with the first embodiment, the portable temperature adjusting device in this embodiment further includes a main body 11 and a cover member 60. Assemblies that realize temperature adjusting functions such as air blowing and contact cooling are primarily located in the main body 11. For example, the main body 11 is provided with an air intake 15, an air exhaust 16, and a heat dissipation vent 14, as well as an air duct 17 that connects the air intake 15 and the heat dissipation vent 14. To realize the temperature adjusting function of the main body 11, a blower 3, a heat dissipation member 5, and a temperature adjusting member 4 are provided within the main body 11 (see FIGS. 33 and 39). The blower 3 is located within the air duct 17 and corresponds to the air intake 15. The heat dissipation member 5 is located within the air duct 17 and corresponds to the heat dissipation vent 14. The temperature adjusting member 4 is located outside the air duct 17 and is thermally conductively connected to the heat dissipation member 5. The temperature adjustment member 4 is, for example, a semiconductor cooling sheet, and can achieve contact cooling functionality by combining it with a temperature conduction member 2 connected to the opposite side of the heat dissipation member 5 of the temperature adjustment member 4 (see Figures 33 and 39). The cover member 60 is connected to the main body 11 and covers the air intake 15 and the heat dissipation port 14. The cover member 60 is provided with a first through-hole array 601 that communicates with the air intake 15 and a second through-hole array 602 that communicates with the heat dissipation port 14.

[0091] In this embodiment, the thickness of the case material of the main body 11 can be set to be thicker, providing a certain level of strength and better protecting the internal assembly. To reduce the difficulty of drilling holes in the case of the main body 11, the air intake 15 may be drilled as a large hole with a diameter close to that of the blower 3. For the same reason, the heat dissipation vent 14 may also be drilled as a larger hole. Both the first through-hole array 601 and the second through-hole array 602 include multiple small holes. The size of the small holes in the first through-hole array 601 is smaller than that of the air intake 15, and the size of the small holes in the second through-hole array 602 is smaller than that of the heat dissipation vent 14. In this way, it is easier to drill larger holes in the main body 11 than to drill multiple small holes directly in the main body 11. By drilling smaller holes in the cover member 60, the thickness of the cover member 60 can be selected to be relatively thin, which is not affected by the thickness of the material of the main body 11, and reduces the difficulty of drilling holes. At the same time, the first through-hole array 601 and the second through-hole array 602 can also prevent foreign objects such as hair from entering. Furthermore, the first through-hole array 601 and the second through-hole array 602 are separately drilled in the cover member 60. The main body 11 in this embodiment may have an arc-shaped structure. When arranging mounting structures for mounting the fan 3, the heat dissipation member 5, and the temperature adjustment member 4 inside, the process of drilling holes in the cover member 60 is not affected by the complex internal structure of the main body 11, making it easy to operate. Furthermore, the cover member 60 can be made of a different material, color, pattern, etc. from the main body 11, allowing for a more diverse design of the portable temperature adjustment device.

[0092] Specifically, the portable temperature adjusting device provided by this embodiment will be described in detail below with reference to the neck-hanging structure shown in FIG.

[0093] FIG. 29 illustrates a schematic diagram of the structure of a neck-worn portable temperature control device. As shown in FIG. 29, this portable temperature control device has an overall U-shaped structure and includes a base 110 and two arms 13 disposed on opposite ends of the base 110. Each of the two arms 13 extends toward one side of the base 110 and, together with the base 110, surrounds and forms an attachment space 10. When worn, the neck of the human body is located within the attachment space 10. Of course, this portable temperature control device may be handheld, neck-worn, belt-type, or the like, and this embodiment is not limited thereto.

[0094] In the portable temperature control device shown in FIG. 29 , the base 110 and the two arms 13 can each be provided with an assembly (i.e., a fan 3, a heat dissipation member 5, a temperature control member 4, etc.) that has an independent temperature control function. In this embodiment, part of the assembly that has the temperature control function may be considered the main body 11, or it may be understood that either the base 110 or one of the two arms 13 independently includes the structure of the main body 11. In one embodiment, the inclusion of the structure of the main body 11 in both the base 110 and the arms 13 can also be understood as meaning that the main body 11 includes the base 110 and the arms 13, and that the base 110 and the arms 13 are provided with an air intake 15 and a heat dissipation port 14 on opposite sides of the mounting space 10, respectively, and that a cover member 60 is connected to these. That is, the cover member 60 is connected to the base 110, and the cover member 60 is also connected to the arms 13.

[0095] 30 to 33 show the structure of the arm portion 13 in this portable temperature regulator.

[0096] Referring to FIG. 30 , this portion of the portable temperature control device includes an arm 13 and a cover member 60. In the orientation shown in FIG. 30 , the generally circular array of holes on the left side of the cover member 60 is a first through-hole array 601, and the generally elongated array on the right side is a second through-hole array 602. Referring to the exploded structural schematic diagram of FIG. 31 , the main body 11 has a mounting groove 134 formed therein. When the cover member 60 is placed in the mounting groove 134, the structure shown in FIG. 30 is formed. The cover member 60 may be fixed to the mounting groove 134 by adhesive bonding or other methods such as a snap-fit ​​connection. In the orientation shown in FIG. 31 , the circular opening on the left side of the main body 11 is the air intake vent 15, and the elongated opening on the right side is the heat dissipation vent 14. When the cover member 60 is attached to the main body 11, the first through-hole array 601 is aligned with the air intake 15 and the second through-hole array 602 is aligned with the heat dissipation vent 14, so that airflow outside the main body 11 can enter the inside of the main body 11 from the first through-hole array 601 via the air intake 15. Airflow from the inside of the main body 11 can be blown out from the second through-hole array 602 via the heat dissipation vent 14.

[0097] Referring to FIG. 32, the case structure of this portion of the main body 11 (i.e., the arm portion 13) can be divided into an outer case 135 and an inner case 136 facing each other. The outer case 135 and the inner case 136 are joined, for example, by screw connection. A receiving cavity 133 is formed between the outer case 135 and the inner case 136 to house the fan 3, the heat dissipation member 5, and the temperature adjustment member 4, and the air duct 17 is further formed surrounding the cavity. The outer case 135 includes an outer case plate 137, and the air intake 15 and the heat dissipation port 14 are disposed on the outer case plate 137. The thickness of the cover member 60 is thinner than the thickness of the outer case plate 137. Because the thickness of the cover member 60 is thinner, the first through-hole array 601 and the second through-hole array 602 are also deeper, which is advantageous for improving the airflow circulation effect.

[0098] In the neck-hanging structure shown in Figure 29, the outer case 135 is located on the opposite side of the inner case 136 from the mounting space 10, so the air intake 15 and heat dissipation vent 14 are located on the opposite side of the main body 11 from the mounting space 10.

[0099] As shown in FIG. 33 , the blower 3 and heat dissipation member 5 are disposed within an inner case 136. A partition member 138 is provided within the inner case 136, dividing the exhaust side of the blower 3 into an exhaust air duct 174 and a heat dissipation air duct 175. The partition member 138 is provided with an air vent 139. A portion of the airflow blown out from the blower 3 passes through the air vent 139 into the heat dissipation air duct 175, comes into contact with the heat dissipation member 5 for heat exchange, and is finally blown out from the heat dissipation port 14. Exhaust ports 16 are provided on the sides of the outer case 135 and the inner case 136 adjacent to the intake port 15. Another portion of the airflow blown out from the blower 3 passes through the exhaust air duct 174 and is blown out from the exhaust port 16, achieving a cooling effect through ventilation. The heat dissipation member 5 includes a plurality of heat dissipation sheets 55, and heat dissipation gaps are formed between adjacent heat dissipation sheets 55. As shown in Figure 33, the multiple heat dissipation sheets 55 extend in the direction from the blower 3 to the heat dissipation outlet 14 (left-right direction), and the length direction of the heat dissipation outlet 14 is perpendicular to the direction in which the multiple heat dissipation sheets 55 extend.In other words, the heat dissipation outlet 14 extends in the up-down direction, so that the multiple heat dissipation gaps can dissipate heat independently.

[0100] 32 , in one embodiment, a display module 80 is further provided in the main body 11. A display window 18 is opened in the main body 11 at a position corresponding to the display module 80. The cover member 60 has a light-transmitting region 603, which covers the display window 18 and is disposed corresponding to the display window 18. In this embodiment, the light-transmitting region 603 refers to an area of ​​the cover member 60 that allows light to pass through the display module 80. In practice, the cover member 60 may be entirely a light-transmitting plate member, or only the light-transmitting region 603 may be a light-transmitting plate member. The cover member 60 can realize a screen display function.

[0101] In some specific embodiments, referring to FIG. 34 , the cover member 60 may include a base 604 and a thin film layer 605 disposed on a side of the base 604 closer to the main body 11. The base 604 may be, for example, a transparent PC (polycarbonate) material, and the thin film layer 605 may be an MMA (polymethyl methacrylate) coating, which may be printed on the base 604 by silkscreen printing, thereby achieving a light-transmitting yet opaque effect. When the cover member 60 covers the main body 11, the portion of the cover member 60 except for the light-transmitting region 603 corresponding to the display module 80 can cover positions such as the screw holes 127 (see FIG. 32 ) on the main body 11, thereby achieving a more aesthetic effect. Because the light-transmitting region 603 is positioned corresponding to the display module 80, the display module 80, covered by the cover member 60, cannot be seen through the light-transmitting region 603 when the display module 80 is not displaying light. When the display module 80 displays light, the light can pass through the light-transmitting area 603 to achieve a display effect.

[0102] The display module 80 may be an LCD display screen or a combination of multiple indicator lights. In some embodiments, the display module 80 includes a light-emitting element 801 and a light-guiding structure 802 disposed on the side of the light-emitting element 801 closest to the cover member 60. The light-guiding structure 802 abuts the light-transmitting region 603 of the cover member 60. The light-emitting element 801 may be, for example, LED lamp beads of the same color or different colors. The light-guiding structure 802 may be, for example, a transparent PC material, and may guide the light emitted from the lamp beads to the cover member 60. A specific light-guiding structure 802 may include multiple light-guiding columns, one for each of the multiple lamp beads, to prevent the light emitted from each lamp bead from interfering with each other. In this embodiment, for example, referring to FIG. 33 , a control circuit board 180 may be further provided within the inner case 136. The light-emitting element 801 is fixed to the control circuit board 180 and electrically connected to the control circuit board 180. The inner case 136 is further provided with a push button switch 40 electrically connected to the control circuit board 180. The control circuit board 180 is electrically connected to the fan 3 and the temperature adjustment member 4, and during use, the push button switch 40 can be used to turn the portable temperature adjustment device on / off, select and adjust functions, and control the fan 3 and the temperature adjustment member 4. Furthermore, when different functions are selected and adjusted, the control circuit board 180 controls the emission of different light emitting elements 801 to achieve display effects.

[0103] In some embodiments, the portable temperature control device further includes a light diffusion sheet 90. The light diffusion sheet 90 covers the display window 18 and is located between the light-transmitting area 603 and the main body 11. The light diffusion sheet 90 has a pattern marking. The light diffusion sheet 90 may be made of PET (polyethylene terephthalate) and light-diffusing powder. For example, referring to FIG. 35, which illustrates an embodiment of the light diffusion sheet 90, the black areas in FIG. 35 represent the material of the light diffusion sheet 90, and the white areas represent the openwork areas of the light diffusion sheet 90. When the light-emitting element 801 located at a position corresponding to the display module 80 emits light, the light passes through the corresponding openwork areas to achieve a display effect. The openwork areas that are not illuminated by light are not displayed due to the principle that the cover member 60 is light-transmitting but not transparent, thereby achieving a display effect while maintaining an aesthetic appearance. The pattern marking on the light diffusion sheet 90 may be letters or graphics, and is not limited to this embodiment.

[0104] 36 to 39 show the structure of the base 110 of this portable temperature control device. As shown in FIG. 36, this portion of the portable temperature control device includes the base 110 and a cover member 60. The exploded structural diagram shown in FIG. 37 shows the internal structure of the side of the main body 11 closest to the cover member 60 and the structure of the side of the cover member 60 closest to the main body 11. The main body 11 is provided with two air intakes 15 and two heat dissipation vents 14, and the two heat dissipation vents 14 are located between the two air intakes 15. Continuing to refer to the exploded structural diagram shown in FIG. 38, one fan 3 is provided at a position corresponding to each of the two air intakes 15, and the heat dissipation member 5 is located between the two fans 3. Referring to the orientation shown in FIG. 38, the heat dissipation member 5 includes two heat dissipation gaps, each of which has multiple heat dissipation sheets, and the inlets of the two heat dissipation gaps are arranged back-to-back. The heat dissipation gap located at the top communicates with the exhaust side of the fan 3 on the right side, and the heat dissipation gap located at the bottom communicates with the exhaust side of the fan 3 on the left side. Accordingly, the number of first through-hole arrays 601 in the cover member 60 is two, and they are arranged corresponding to the two air intake ports 15, respectively. The second through-hole array 602 is arranged between the two first through-hole arrays 601 corresponding to the heat dissipation port 14. Note that a plurality of small holes are provided on the outer surface (opposite the main body portion 11) of the cover member 10 shown in Figures 36 and 37, and the portions thereof other than the first through-hole array 601 and the second through-hole array 202 are blind holes.

[0105] 38 , for example, a relay circuit board 181 is further provided inside the inner case 136 of the base 110, and the two fans 3 and the temperature adjustment member 4 inside the base 110 can be electrically connected to the relay circuit board 181 via conductors. The relay circuit board 181 is electrically connected to the control circuit board 180 via conductors, and can control the operation of the fans 3 and the temperature adjustment member 4 inside the base 110 and the arm 13, respectively, via the push button switch 40 on the arm 13.

[0106] In some embodiments, both the inner case 136 and the outer case 135 are curved in a direction from the outer case 135 to the inner case 136. Referring to FIG. 40 , taking the orientation of the base 110 as an example, both the inner case 136 and the outer case 135 are curved downward, and a positioning groove 1361 is provided at the end of the inner case 136. Referring to both FIG. 38 and FIG. 40 , the positioning grooves 1361 are located at both the left and right ends of the inner case 136, two on each end, for a total of four positioning grooves 1361. For more details, see the partially enlarged schematic diagram of region A in FIG. 41 . An inclined groove surface 1362 is formed on the side of the positioning groove 1361 closer to the center of the inner case 136, and the inclined groove surface 1362 is inclined in a direction from the end to the center of the inner case 136. 43, a positioning member 1351 is provided on the outer case 135 near the inner case 136, and the positioning member 1351 is coupled to the positioning groove 1361. More specifically, the positioning member 1351 is provided with a positioning inclined surface 1352 that matches the inclined groove surface 1362. The inner case 136 is further provided with a fixing post 1363. After passing through the positioning groove 1361, the positioning member 1351 is fixed to the fixing post 1363 with a screw, thereby fixing the inner case 136 and the outer case 135 together and forming the joined structure shown in FIG. 42. According to the orientation shown in FIG. 40, if the outer case 135 needs to be attached to the inner case 136 facing downward, the curvature is relatively large, and therefore the arrangement of the inclined groove surface 1362 can prevent the outer case 135 and the inner case 136 from interfering with each other when joined. Specifically, also referring to the exploded structural schematic diagram of the inner case 136 side in FIG. 39 , the inner case 136 is further provided with, for example, a connecting member 1364. The connecting member 1364 may be a nylon member for realizing the connection between the base 110 and the arm portion 13. Specifically, the positioning groove 1361 may be provided in the connecting member 1364. Similarly, the inner case 136 of the arm portion 13 may also be provided with a connecting member 1364. Furthermore, for example, a flexible connecting member 1021 is further provided between the base 110 and the arm portion 13.The flexible connecting member 1021 may be made of silicone rubber and fitted onto the connecting member 1364 of the base 110 and the connecting member 1364 of the arm portion 13, thereby realizing the connection between the arm portion 13 and the base 110, and adjusting the angle between the base 110 and the arm portion 13 to facilitate attachment.

[0107] As described above in the case where the arm portion 13 is the main body portion 11, when the base portion 110 is the main body portion 11, structures such as an attachment groove 134 and a display module 80 can also be provided, but this embodiment is not limited to this.

[0108] 44 to 48, a portable temperature control device provided by a seventh embodiment of the present application is worn on the human body, for example, around the neck, and is used to control the temperature of the human body, for example, by blowing air, cooling, or heating. Compared to the sixth embodiment, the portable temperature control device of this embodiment includes a main body 11, a temperature control assembly provided within the main body 11, and a color-changing body provided on the main body 11. After being exposed to sunlight, the color-changing body changes color depending on the intensity of ultraviolet light in the sunlight. This color change detects and identifies the intensity of ultraviolet light in the sunlight, and the color-changing effect of the color-changing body can be used to identify the intensity of ultraviolet light in the sunlight, which helps the user determine whether protective measures are necessary. Furthermore, the portable temperature control device can generate a color change in the color-changing body in a sunlight-exposed environment, creating an eye-catching effect and enhancing fashion, fun, and a sense of technology, thereby improving the user's experience.

[0109] The color change of the color-changing body may be in various ways. For example, the stronger the ultraviolet light, the darker the color of the color-changing body, i.e., the color may change to different shades of orange, such as from light orange to dark orange. Alternatively, the stronger the ultraviolet light, the different colors may change, such as from gray to red. Alternatively, when the ultraviolet light reaches a certain intensity, for example, when the ultraviolet light intensity reaches 75 mW / m 2 When the temperature reaches 100° C., the color change body undergoes a color change, such as changing from black to red.

[0110] In the illustrated embodiment, the color-changing body is implemented as an ultraviolet-color-changing layer 100 provided on the surface of the main body 11. The ultraviolet-color-changing layer 100 can change color depending on the intensity of ultraviolet light after being irradiated with sunlight. Preferably, the ultraviolet-color-changing layer 100 is disposed on the upper surface of the main body 11. For example, the ultraviolet-color-changing layer 100 is designed to conform to the shape of the main body 11 so as to cover the entire upper surface. For example, the upper surface of the main body 11 may have an uneven, undulating structure, and the ultraviolet-color-changing layer 100 may be designed to have an uneven structure that fits snugly thereto. The ultraviolet-color-changing layer 100 may be ultraviolet-color-changing ink applied to the surface of the main body 11, for example, by silkscreen printing. The ultraviolet-color-changing layer 100 may be a hard or soft cover member made of an ultraviolet-sensitive material. The UV-chromic layer 100 can be detachably fixed to the top surface of the main body 11 by adhesive, snap fastening, or other methods, allowing the user to easily replace the UV-chromic layer 100 if it malfunctions or becomes damaged. Furthermore, since the top surface of the main body 11 is easily visible to the user, the UV-chromic layer 100 is provided on the top surface, allowing the user to quickly detect any discoloration of the UV-chromic layer 100 and easily determine whether or not protective measures are necessary.

[0111] In some embodiments, the main body 11 may be made of, for example, a plastic material, and the color-changing substance may be implemented as an ultraviolet-induced color-changing powder. That is, when the ultraviolet-induced color-changing powder is irradiated with sunlight, the ultraviolet-induced color-changing powder undergoes different color changes depending on the intensity of the ultraviolet rays in the sunlight. When manufacturing the main body 11, the plastic raw material of the main body 11 and the ultraviolet-induced color-changing powder are mixed and molded into a plastic part (the color-changing main body 11) using an injection molding method. That is, the color-changing substance and the main body 11 are integrated, and the color-changing substance is dispersed in the case material to create a color-changing case. When the ultraviolet intensity changes, the entire main body 11 undergoes a corresponding color change. In other embodiments, the ultraviolet-induced color-changing powder and at least a portion of the main body 11 may be manufactured using the above-mentioned mixing and injection molding method, so that localized portions of the main body 11 can be color-changed. When the ultraviolet intensity changes, localized portions of the main body 11 undergo a corresponding color change.

[0112] In the illustrated embodiment, a color comparator is provided on the main body 11 to enable a user to quickly and accurately identify the UV intensity corresponding to the color of the color variable. The color comparator can be used to compare the color with the color variable. Based on the comparison result, the user can quickly determine whether protective measures need to be taken. In some embodiments, the color comparator may be set to only one fixed color. If the color variable changes to this color, it indicates that the UV intensity exceeds a preset standard and protective measures need to be taken. If the color variable does not change color, it indicates that the UV intensity does not exceed the preset standard and no protective measures need to be taken.

[0113] In this embodiment, the colorimetric body includes several colorimetric regions 102 with different fixed colors. That is, the colorimetric body has multiple fixed colors, each color of which is different from the other colorimetric regions 102, and each color corresponds to a different UV intensity. By comparing the color of the colorimetric body with the color of the colorimetric regions 102, the current UV intensity can be determined, and whether protective measures need to be taken can be determined. The several colorimetric regions 102 may be arranged adjacent to each other in sequence, for example, along the width, thickness, or length of the main body 11. In the illustrated embodiment, three colorimetric regions 102 are provided, and the three colorimetric regions are arranged adjacent to each other in sequence along the width direction of the main body 11.

[0114] Optionally, the color comparator may be disposed on the main body 11, for example, on the outer surface of the main body 11, or may be disposed on the ultraviolet color-changing layer 100 of the main body 11 to facilitate comparison and visual identification by the user.

[0115] In some embodiments, the color-changing body may include several color-changing regions with different UV-sensing intensities. A user can determine the UV intensity based on the color change of each color-changing region and determine whether protective measures are necessary. For example, three color-changing regions may be provided, each corresponding to a first, second, and third color-changing region, each corresponding to a different UV intensity. If only the first color-changing region changes color, this indicates that the UV intensity is relatively weak and will not have a significant impact on the human body. If only the first and second color-changing regions change color, this indicates that the UV intensity is moderate, and protective measures are necessary. If all three color-changing regions change color, this indicates that the UV intensity is relatively strong, and better protective measures are necessary, or the user should avoid staying outdoors.

[0116] In the illustrated embodiment, the main body 11 includes a case 120 and a cover member 60. A temperature adjustment assembly that realizes temperature adjustment functions such as air blowing and contact cooling is mainly disposed in the case 120. For example, the case 120 is provided with an air intake 15, an exhaust 16, and a heat dissipation vent 14, as well as an air duct that connects the air intake 15 and the heat dissipation vent 14. The main body 11 surrounds the mounting space 10, and the exhaust vent 16 is disposed, for example, on the top wall of the main body 11. The color-changing body may be disposed on the top wall of the main body 11 or on a side wall of the main body 11 that is distant from the mounting space 10.

[0117] The color-changing body may be arranged in the case 120 and / or the cover member 60 in the various design manners described above. In this embodiment, the color-changing body is implemented as an ultraviolet color-changing layer 100 and is arranged on the upper wall of the case 120. The color-changing body is arranged at the outer edge of the photosensitive layer 14 to facilitate the user's visual recognition and comparison of colors. The ultraviolet color-changing layer 100 is provided with an exhaust hole 104 corresponding to the exhaust port 16 of the case 120 so as not to affect the airflow.

[0118] In some embodiments, the color-changing element is disposed on the cover member 60, for example, on the cover member 60 corresponding to the base 110 or on the cover member 60 corresponding to the arm 13. The color-changing element may be provided as letters or graphics to display product information, such as the product brand name or product name. Specifically, when there is no sunlight or the UV intensity in the sunlight is relatively low, the product information can be set not to be displayed. When the UV intensity in the sunlight becomes sufficient, the product information turns orange and is displayed. Preferably, the color-changing element is disposed on the outer surface of the bottom-protruding portion of the cover member 60 corresponding to the base 110 by silkscreen printing to facilitate external display.

[0119] 49 to 54, an eighth embodiment of the present application provides a portable temperature adjusting device. Compared with the sixth embodiment, the portable temperature adjusting device in this embodiment further includes, for example, a first case 153, a first inner sheet 154, and a first fan 200.

[0120] In this embodiment, the portable temperature regulating device may be a handheld fan, a neck fan, a head-mounted fan, a waist-mounted fan, etc. For convenience of explanation, the following embodiments will be described taking the portable temperature regulating device as a neck fan as an example.

[0121] Specifically, the portable temperature regulator further includes a connection structure 400 and a second case 155. There are two first cases 153. The two first cases 153 are connected to both ends of the second case 155, respectively, and both are connected via the connection structure 400. That is, both ends of the second case 155 are provided with the connection structure 400, and are connected to the first case 153 via the connection structure 400. The first case 153 and the second case 155 are suitable for being worn around the neck of a human body.

[0122] The first case 153 is provided with a first air intake port 151 and a first air exhaust port 161. The first air intake port 151 is disposed, for example, on a side wall of the first case 153 that is away from the neck of the human body, and the first air exhaust port 161 is disposed, for example, on an upper wall of the first case 153. The first inner sheet 154 is attached to the inside of the first case 153. The first inner sheet 154 is provided with a housing cavity 1541, and the first air intake port 151 communicates with the housing cavity 1541. The first inner sheet 154 is provided with an air guide passage 1542, and the housing cavity 1541 communicates with the first air exhaust port 161 via the air guide passage 1542. The first fan 200 is disposed within the housing cavity 1541. Here, the air guide passage 1542 may have a groove structure or a duct structure. Specifically, the air guide passage 1542 in this embodiment has a groove structure. The first inner sheet 154 is disposed inside the first case 153. The first inner sheet 154 has a accommodating cavity 1541 and an air guide passage 1542 that communicate with each other. The first fan 200 is disposed within the accommodating cavity 1541 and forms an exhaust module together with the first inner sheet 154. This allows the air generated by the first fan 200 to quickly pass through the air guide passage 1542 and be discharged through the first exhaust port 161, ensuring smooth air discharge. This solves the problem of noise generation due to gaps created when the accommodating case and the wind-driven fan are installed separately in the prior art. Furthermore, the first fan 200 is attached to the first inner sheet 154 to form an independent exhaust module. This eliminates the need to adjust the size compatibility between the first fan 200 and the first case 153 during production, compared to the prior art. This modular design simplifies product production and manufacturing.

[0123] In a more preferred embodiment of this embodiment, the first inner sheet 154 includes a first portion and a second portion connected to each other. The first portion forms a receiving cavity 1541. The second portion includes a first air guide portion 1543 and a second air guide portion 1544, and the first air guide portion 1543 is connected to one side of the second air guide portion 1544. The first air guide portion 1543 and the second air guide portion 1544 are both plate-shaped and are installed at an angle to each other, thereby forming an air guide passage 1542 with a groove structure.

[0124] In another embodiment, first air guide section 1543 and second air guide section 1544 both have a frame structure that opens laterally, and are connected to each other by snap-fitting, thereby forming air guide passage 1542 with a duct structure. Also, first inner sheet 154 needs to be provided with a ventilation hole at a position corresponding to first exhaust port 161. The ventilation hole may be disposed, for example, at the connection point between first air guide section 1543 and second air guide section 1544, so that air that has entered air guide passage 1542 can be blown out from first exhaust port 161 via the ventilation hole.

[0125] In a more preferred embodiment of this embodiment, the first portion includes a side wall 1545 and a bottom wall 1546 connected to each other. The side wall 1545 surrounds the bottom wall 1546 to form an accommodating cavity 1541. A mounting post 1547 is provided on the bottom wall 1546, and the mounting post 1547 is located within the accommodating cavity 1541. The first fan 200 is, for example, a centrifugal fan. Correspondingly, a volute tongue 1548 is provided on the side wall 1545, and the volute tongue 1548 is located adjacent to the upper wall of the first case 153. A motor (not shown) of the first fan 200 is fixed to the mounting post 1547. The fan blades of the first fan 200 rotate when driven by the motor (not shown) to generate airflow. By fixing the motor of the first fan 200 to the mounting post 1547, the first fan 200 and the first inner sheet 154 can form a module. If the first fan 200 is damaged after long-term use, the module formed by the first inner sheet 154 and the first fan 200 can be quickly removed from the first case 153 and replaced, solving the problem in the prior art that it is difficult to remove or replace the fan because the fan is attached and fixed to the mounting post of the case.

[0126] Furthermore, the side wall 1545 is provided with a first avoidance notch 1549 and a second avoidance notch 1540 arranged opposite to each other, and the communication point between the air guide passage 1542 and the accommodating cavity 1541 is located between the first avoidance notch 1549 and the second avoidance notch 1540. Specifically, the first avoidance notch 1549 is arranged close to the top wall of the first case 153, and the second avoidance notch 1540 is arranged close to the bottom wall of the first case 153. Compared to a first inner sheet in which the side wall 1545 does not have the first avoidance notch 1549 and the second avoidance notch 1540, if the diameter of the fan blades of the first blower 200 does not change, by providing the side wall 1545 with the first avoidance notch 1549 and the second avoidance notch 154, the thickness between the top wall and the bottom wall of the first case 153 can be reduced, and at the same time the top wall and the bottom wall of the first case 153 will no longer interfere with the fan blades of the first blower 200, allowing the first blower 200 to be installed more compactly inside the first case 153.

[0127] In a more preferred embodiment of this embodiment, the first air outlet 161 includes a first sub-air outlet 1611 and a second sub-air outlet 1612, and the air guide passage 1542 includes a first sub-air outlet 15421 and a second sub-air outlet 15422. The first sub-air outlet 15421 and the second sub-air outlet 15422 are located on opposite sides of the first air guide section 1543. The first sub-air outlet 1611 communicates with the accommodating cavity 1541 via the first sub-air outlet 15421, and the second sub-air outlet 1612 communicates with the accommodating cavity 1541 via the second sub-air outlet 15422. By providing the first sub-air outlet 1611 and the second sub-air outlet 1612 side by side on one side of the first case 153, the air exhaust range of the portable temperature controller is expanded, improving the user experience. At the same time, the first sub-exhaust port 1611 is independently connected to the accommodating cavity 1541 through the first sub-passage 15421, and the second sub-exhaust port 1612 is independently connected to the accommodating cavity 1541 through the second sub-passage 15422, thereby ensuring that the wind passing through the first sub-passage 15421 and the second sub-passage 15422 does not interfere with each other.

[0128] Furthermore, first air guide section 1543 includes two sub-air guide sections 15431 at one end closer to first fan 200 and two extension sections 15432 respectively connected to the two sub-air guide sections 15431. The two sub-air guide sections 15431 are connected to each other at one end closer to first fan 200 to form a V-shaped air guide end, which is advantageous for dividing the airflow generated by first fan 200 into two parts flowing toward first sub-passage 15421 and second sub-passage 15422, respectively, and reducing wind resistance. The V-shaped air guide end is also connected to the side of volute tongue 1548 away from first fan 200, thereby allowing air to enter first sub-passage 15421 and second sub-passage 15422 more smoothly. The distance between the two sub-air guidance sections 15431 gradually increases in width direction from one end of the first case 153 close to the first fan 200 toward the direction away from the first fan 200, i.e., gradually increases along the flow direction of the airflow, and the two extension sections 15432 extend along the length direction of the first case 153, are spaced apart from each other, and are parallel to each other.

[0129] Furthermore, the first inner sheet 154 further includes a first air guide sheet 162, a first blocking portion 163, a second air guide sheet 164, and a second blocking portion 165. One side of the first blocking portion 163 is connected to one side of one of the extension portions 15432. The first blocking portion 163 extends at an angle along the thickness direction of the first case 153. One end of the first blocking portion 163 remote from the first fan 200 is positioned closer to the top wall of the first case 153 than the other end of the first blocking portion 163 closer to the first fan 200. The other end of the first blocking portion 163 close to the first fan 200 is connected to one end of the second air guide portion 1544 remote from the first fan 200. After the airflow generated by first fan 200 is blown into first sub-passage 15421, it is blocked and guided by first blocking portion 163 and blown out through first sub-exhaust port 1611. This prevents the airflow from passing through first blocking portion 163 and blowing toward a location further away from first fan 200. Two first air guide sheets 162 may be provided. The two first air guide sheets 162 are spaced apart in first sub-passage 15421 and are located between accommodating cavity 1541 and first blocking portion 163. One side of each first air guide sheet 162 is connected to one side of one sub-air guide portion 15431. The first air guide sheet 162 extends at an angle along the thickness direction of first case 153. One end of first air guide sheet 162 remote from first fan 200 is positioned closer to the upper wall of first case 153 than the other end of first air guide sheet 162 closer to first fan 200. A ventilation gap is provided between the other end of first air guide sheet 162 close to first fan 200 and second air guide section 1544. By providing first air guide sheet 162 in first sub-passage 15421, air can be blown out uniformly from first sub-exhaust port 1611.

[0130] One side of the second blocking portion 165 is connected to one side of the other sub-airflow guide portion 15431. The second blocking portion 165 extends at an angle along the thickness direction of the first case 153. One end of the second blocking portion 165 remote from the first fan 200 is positioned closer to the top wall of the first case 153 than the other end of the second blocking portion 165 closer to the first fan 200. The other end of the second blocking portion 165 remote from the first fan 200 is connected to one end of the second airflow guide portion 1544 remote from the first fan 200. After the air generated by the first fan 200 is blown into the second sub-passage 15422, the air is blocked and guided by the second blocking portion 165 and blown out from the second sub-exhaust port 1612. Therefore, the air cannot pass through the second blocking portion 165 and be blown toward a location farther away from the first fan 200. For example, there may be only one second air guide sheet 164. The second air guide sheet 164 is disposed in the first sub-passage 15421 and is located between the accommodation cavity 1541 and the second blocking section 165. One side of the second air guide sheet 164 is connected to one side of the other sub-air guide section 15431. The second air guide sheet 164 extends at an angle along the thickness direction of the first case 153. One end of the second air guide sheet 164 remote from the first fan 200 is disposed closer to the upper wall of the first case 153 than the other end of the second air guide sheet 164 closer to the first fan 200. A ventilation gap is provided between the other end of the second air guide sheet 164 close to the first fan 200 and the second air guide section 1544. By providing the second air guide sheet 164 in the second sub-passage 15422, air can be uniformly blown out from the second sub-exhaust port 1612. Because the amount of air entering the first sub-passage 15421 is greater than the amount of air entering the second sub-passage 15422, the length of the first sub-passage 15421 can be set longer than the length of the second sub-passage 15422, thereby allowing the air to be blown out from the first sub-exhaust port 1611 over a wider area.

[0131] In a more preferred embodiment of this embodiment, the side of the second airflow guide section 1544 away from the first airflow guide section 1543 forms a heat dissipation cavity 166 together with the first case 153. The first inner sheet 154 is provided with a ventilation hole 139 that connects the heat dissipation cavity 166 to the accommodation cavity 1541. The ventilation hole 139 may be located in the first section, the second section, or the connection between the first section and the second section. The first case 153 is further provided with a heat dissipation hole 14 that connects to the heat dissipation cavity 166. The heat dissipation hole 14 is located on a side wall of the first case 153 that is away from the neck of the human body. Specifically, heat-generating devices such as the battery 510, the circuit board 180, and the heat dissipation member 5 of the portable temperature adjusting device may all be accommodated in the heat dissipation cavity 166. A portion of the airflow generated by the first fan 200 is blown into the heat dissipation cavity 166 through the ventilation opening 139, and the airflow then blows the hot air emitted from the heat-generating device out through the heat dissipation opening 14, thereby dissipating the heat from the heat-generating device and preventing problems such as the heat-generating device becoming too hot and being easily damaged or affecting the temperature regulation performance of the portable temperature control device. A cover member 60 may be further attached to a side wall of the first case 153 away from the neck. A first through-hole array 601 is formed in the cover member 60 at a position corresponding to the first air intake opening 151. A second through-hole array 602 is formed in the cover member 60 at a position corresponding to the heat dissipation opening 14. The first through-hole array 601 in the cover member 60 prevents hair or clothing from getting caught in the first fan 200, and the second through-hole array 602 in the cover member 60 prevents a person from accidentally touching the heat-generating device and getting burned.

[0132] In a more preferred embodiment of this embodiment, the portable temperature regulating device further includes a heat dissipation member 5, a temperature adjustment member 4, and a temperature conduction member 2. The heat dissipation member 5 is disposed within the heat dissipation cavity 166. The temperature conduction member 2 is fixedly connected to the first case 153 and exposed to the outside of the first case 153. The temperature conduction member 2 is disposed, for example, on a side wall of the first case 153 close to the neck of the human body. The heat dissipation member 5 and the temperature conduction member 2 are each thermally connected to the temperature adjustment member 4. The temperature adjustment member 4 is specifically a semiconductor cooling sheet. The temperature conduction member 2 is an aluminum alloy temperature conduction member. When activated, the temperature adjustment member 4 transfers cool air to the temperature conduction member 2, which then transfers the cool air to the human body, thereby cooling the human body. At the same time, the heat generated by the temperature adjustment member 4 is transferred to the heat dissipation member 5, which dissipates the hot air into the heat dissipation cavity 166. The first fan 200 generates wind, some of which is blown toward the heat dissipation cavity 166, carrying the hot air dissipated by the heat dissipation member 5, and then blown out through the heat dissipation port 14. Naturally, the temperature adjustment member 4 can also transfer the hot air to the temperature conduction member 2, which then transfers the hot air to the human body to warm it.

[0133] The first inner sheet 154 further includes a mounting portion 167 and a barrier portion 168. The mounting portion 167 is connected to one end of the second air guide portion 1544 remote from the first portion, and the mounting portion 167 and the first air guide portion 1543 are located on opposite sides of the second air guide portion 1544. The barrier portion 168 is connected to the mounting portion 167 and the second air guide portion 1544, respectively. The barrier portion 168, the mounting portion 167, the second air guide portion 1544, and the first case 153 together form a heat insulating cavity 169 for accommodating a power source. The barrier portion 168 is located between the heat insulating cavity 169 and the heat dissipation cavity 166. The power source is a battery 510, which is used to supply power to power consumption units, such as the first fan 200 and the temperature adjustment member 4. Since the internal space of the first case 153 is limited, in order to prevent the heat from the heat dissipation cavity 166 from being transferred to the power supply, a barrier 168 is used to separate the power supply from the heat dissipation cavity 166, so that the power supply is not affected by the heat from the heat dissipation cavity 166.

[0134] In a more preferred embodiment of this embodiment, the heat dissipation member 5 includes a substrate 56, an extension 57, and a heat dissipation sheet 55. The heat dissipation sheet 55 is connected to one side of the substrate 56 and is located within the heat dissipation cavity 166. The extension 57 is connected to one end of the substrate 56 and is located between the temperature conduction member 2 and the second portion. Both the extension 57 and the substrate 56 are thermally conductively connected to the temperature adjustment member 4. Specifically, there are multiple heat dissipation sheets 55, and multiple heat fins are spaced apart on one side of the substrate 56. Connecting the extension 57 to one end of the substrate 56 and connecting both the extension 57 and the substrate 56 to the temperature adjustment member 4 increases the size of the temperature adjustment member 4, thereby improving the temperature adjustment effect. Furthermore, the arrangement of the extension 57 and the substrate 56 increases the thermal conduction area between the heat dissipation member 5 and the temperature adjustment member 4, thereby improving the heat dissipation ability of the heat dissipation member 5 to the temperature adjustment member 4.

[0135] Furthermore, an escape opening 176 is further provided in the first inner sheet 154. The escape opening 176 is located directly below the second sub-passage 15422 that is closer to the first fan 200, and the escape opening 176 communicates with the heat dissipation cavity 166. The extension portion 57 is disposed within the escape opening 176 to prevent interference between the heat dissipation member 5 and the first inner sheet 154. Furthermore, because the entire heat dissipation sheet 55 is disposed within the heat dissipation cavity 166, the heat dissipation member 5 and the first inner sheet 154 can be mounted compactly inside the first case 153.

[0136] In a more preferred embodiment of this embodiment, the temperature conducting member 2 is provided with a pearlescent paint layer or is mixed with pearlescent powder. The pearlescent paint layer is mainly formed of pearlescent paint. Pearlescent paint (also known as mica paint) is a reflective top coat in which mica is used instead of aluminum particles, and mica pigment coated with titanium dioxide and iron oxide is added to the paint base. When light hits the mica particles, it is refracted, thereby providing the temperature conducting member 2 with a more eye-catching visual effect. The pearlescent powder can be pearlescent white (i.e., white pearlescent powder). When light hits the pearlescent powder, it is refracted, thereby providing the temperature conducting member 2 with a more eye-catching visual effect.

[0137] In a more preferred embodiment of this embodiment, a temperature-sensitive layer is provided on the surface of the temperature conducting member 2. The temperature-sensitive layer may be a temperature-sensitive ink, which can exhibit different colors according to the temperature change of the temperature conducting member 2, making it easier for users to recognize the temperature status of the temperature conducting member 2 and providing a more eye-catching visual effect. For example, when the temperature of the temperature conducting member 2 does not exceed 31°C, the temperature-sensitive layer exhibits blue; when the temperature of the temperature conducting member 2 exceeds 31°C, the temperature-sensitive layer exhibits orange. Naturally, the temperature-sensitive layer can be configured to exhibit other color changes according to user needs.

[0138] As shown in Figures 55 and 56, a ninth embodiment of the present application provides a miniature centrifugal impeller 30 that can be applied to, for example, the portable temperature adjustment device described in any of the first to eighth embodiments above. Specifically, the miniature centrifugal impeller 30 includes, for example, a hub 31 and a plurality of fan blades 32. To explain it here, the miniature centrifugal impeller 30 is a miniature windmill that takes in wind in the axial direction, expels wind in the radial direction, and uses centrifugal force to do work and increase the pressure of the air.

[0139] Specifically, the hub 31 is used, for example, to provide support for a plurality of fan blades 32, and is also used, for example, to house a rotor and a stator of a fan assembly. As shown in Fig. 57, the hub 31 includes, for example, a first end face 311, a second end face 312, and an outer surface 313. The first end face 311 and the second end face 312 are arranged opposite each other, and the outer surface 313 is connected between the first end face 311 and the second end face 312.

[0140] As described above, the multiple fan blades 32 are connected to the outer surface 313 and are arranged around the hub 31, more specifically, the multiple fan blades 32 are arranged at intervals in sequence along the circumferential direction of the outer surface 313. The multiple fan blades 32 extend along a first direction facing from the first end surface 311 to the second end surface 312 and extend beyond the second end surface 312 to surround the intake space SP1, i.e., the intake space SP1 is located on the side of the second end surface 312 away from the first end surface 311.

[0141] In this way, in the embodiment of the present application, by connecting a plurality of fan blades 32 to the outer surface 313 of the hub 31, the arrangement of the plurality of fan blades 32 and the intake space SP1 ensures the exhaust intake effect of the miniature centrifugal impeller 30, and the arrangement of the hub 31 ensures that a miniature motor for a miniature centrifugal fan can still be attached to the miniature centrifugal impeller 30. By eliminating the partition plate structure used in the prior art, the weight of the miniature centrifugal impeller 30 is reduced, the torque of the miniature motor is reduced, heat generation of the miniature motor is reduced, and the rotation speed of the miniature motor is stabilized, thereby ensuring the service life and stable exhaust of the miniature centrifugal fan.

[0142] 57, the outline size D2 of one end of the plurality of fan blades 32 adjacent to the second end surface 312 is larger than the outline size D1 of one end of the plurality of fan blades 32 adjacent to the first end surface 311. With this arrangement, there can be sufficient space to provide a larger intake space SP1 at one end of the plurality of fan blades 32 adjacent to the second end surface 312. Furthermore, because the outline size of the plurality of fan blades 32 gradually increases along the first direction, a draft angle can be formed on the outer periphery of the plurality of fan blades 32, which is advantageous for demolding the miniature centrifugal impeller 30.

[0143] 57, each fan blade 32 includes, for example, a blade portion 321 and a connecting portion 322. The blade portion 321 extends in the first direction, past the second end surface 312, and surrounds the intake space SP1. The connecting portion 322 is connected between the blade portion 321 and the outer surface 313, and the connecting portion 322 is connected to one end of the outer surface 313 that is close to the first end surface 311. Since the size W1 of the connecting portion 322 is smaller than the size W2 of the blade portion 321 in the first direction, an intake gap SP4 is formed between the blade portion 321 and the outer surface 313, and the intake gap SP4 communicates with the intake space SP1. In this way, more airflow can enter the interior of the blade portion 321, increasing the intake airflow, which is advantageous for improving the blowing effect of the small centrifugal impeller 30. 56, a ventilation gap SP5 is formed between the connection portions 322 of two adjacent fan blades 32, and the ventilation gap SP5 communicates with the intake gap SP4. In this way, the multiple connection portions 322 can also do work on the airflow, which is advantageous for improving the air-blowing effect of the small centrifugal impeller 30.

[0144] In another embodiment of the present application, as shown in Figure 56, the small centrifugal impeller 30 further includes a reinforcing rib 33, which is connected to the plurality of blades 321. In this way, the overall rigidity and strength of the plurality of blades 321 can be improved.

[0145] As described above, as shown in FIGS. 56 and 57 , the reinforcing rib 33 includes, for example, a first reinforcing rib 331. The first reinforcing rib 331 is connected to one end of each of the blades 321 that is adjacent to the second end faces 312. The reinforcing rib 33 further includes, for example, a second reinforcing rib 332. The second reinforcing rib 332 is connected to one end of each of the blades 321 that is adjacent to the first end faces 311. The first projection region T331 of the first reinforcing rib 331 on a projection plane perpendicular to the first direction is offset from the second projection region T332 of the second reinforcing rib 332 on the projection plane. In other words, the first projection region T331 and the second projection region T332 do not overlap. This is advantageous in improving the ease of molding the first reinforcing rib 331 and the second reinforcing rib 332.

[0146] 57, the fan blades 32 extend in the direction opposite to the first direction beyond the first end face 311 to surround an avoidance space SP2, i.e., the avoidance space SP2 is located on the side of the first end face 311 away from the second end face 312. The avoidance space SP2 is used to accommodate the circuit board of the fan assembly, and effectively prevents contact or friction between the circuit board and the mini centrifugal impeller 30, not only avoiding damage to the product but also reducing the overall height of the mini centrifugal blower.

[0147] The hub 31 also has a housing cavity SP3, the opening of which is located on the first end surface 311. The housing cavity SP3 is used to mount a small motor for a small centrifugal fan. Furthermore, as shown in FIG. 57 , a rotating shaft mounting portion 34 is provided at a middle position on the first end surface 311. The rotating shaft mounting portion 34 extends along the first direction into the air intake space SP1. This allows the rotating shaft mounting portion 34 to have a sufficient height for mounting the rotating shaft, thereby reducing the space occupied by the rotating shaft in the housing cavity SP3 and facilitating mounting the small motor for a small centrifugal fan in the housing cavity SP3. The rotating shaft mounting portion 34 has a rotating shaft insertion hole 341. The rotating shaft insertion hole 341 is used to mount the rotating shaft to reduce radial vibration between the rotor and the stator.

[0148] As shown in Figures 59 and 60, a tenth embodiment of the present application provides a portable temperature control device. The portable temperature control device may be, for example, a neck-mounted fan or a fan such as a handheld portable fan. Specifically, the portable temperature control device includes, for example, a main body 11 and a miniature centrifugal impeller 30. A volute casing 19 is provided inside the main body 11. The miniature centrifugal impeller 30 is mounted within the volute casing 19. The miniature centrifugal impeller 30 is, for example, the miniature centrifugal impeller provided by the ninth embodiment described above.

[0149] Typically, the portable temperature control device further includes a small motor. The small motor is, for example, a stepping motor, and is used to drive the rotation of the small centrifugal impeller 30. The small motor includes, for example, a rotor and a stator. The stator is fixed to the inner wall of the main body 11, and the rotor is fitted onto the outside of the stator and is rotatable relative to the stator. The rotor is connected to the hub 31 of the small centrifugal impeller 30.

[0150] 60, the portable temperature control device may be, for example, a neck-mounted fan. Therefore, the main body 11 is curved to form the mounting space 10, and an air intake 15 is provided on one side of the main body 11, away from the mounting space 10. The air intake 15 communicates with the volute casing 19 and corresponds to the air intake space SP1 of the small centrifugal impeller 30. When the small centrifugal impeller 30 rotates, the air intake space SP1 can be formed into a space with low resistance and high negative pressure, and the airflow entering through the air intake 15 can be drawn into the air intake space SP1. In this embodiment, the small centrifugal impeller 30 receives air only from one side; that is, the airflow entering through the air intake 15 enters the air intake space SP1 only from the direction opposite to the first direction. Therefore, the corresponding main body 11 may be provided with only one air intake 15 on one side. Specifically, by providing the air intakes 15 only on the side of the main body 11 away from the mounting space 10, it is possible to reduce the possibility of the user's hair being sucked into the air intakes 15 or the volute casing 19, reduce the possibility of hair getting tangled in the small centrifugal impeller 30, and improve product safety. Furthermore, as shown in Figure 61, there may be multiple air intakes 15. All of the multiple air intakes 15 are located on the side of the main body 11 away from the mounting space 10, i.e., no air intakes 15 are provided on the side of the main body 11 close to the mounting space 10.

[0151] In one embodiment of the present application, as shown in Figure 62, the blade portion 321 of each fan blade 32 has an outer edge 323 and an inner edge 324. In some embodiments, the curved direction of each blade portion 321 extending from the inner edge 324 to the outer edge 323 is aligned with the rotation direction of the miniature centrifugal impeller 30. Correspondingly, the miniature centrifugal impeller 30 is a forward-inclined centrifugal impeller. A forward-inclined centrifugal impeller is advantageous for designing a miniature centrifugal impeller, since the wind pressure of the air blown from the blades is large at low rotational speeds and a small motor with a relatively small output can be selected. Furthermore, as can be seen from the structure of the volute casing 19 and the small centrifugal impeller 30 after assembly in Figure 63, the distance from the volute tongue to the outer circle having the diameter D of the small centrifugal impeller 30 from the inner wall of the volute casing 19 gradually increases along the rotation direction of the small centrifugal impeller 30 (for example, clockwise), for example, gradually increasing from L1 to L2. When the small centrifugal impeller 30 is a forward-inclined centrifugal impeller, the curvature direction of each blade portion 321 is along the rotation direction of the small centrifugal impeller 30, so the airflow that enters the inside of the small centrifugal impeller 30 continues to be strengthened in the rotation direction of the small centrifugal impeller 30 in the space where the distance between the small centrifugal impeller 30 and the inner wall of the volute casing 19 gradually increases under the action of each blade portion 321, thereby further improving the wind pressure of the air blown out from the small centrifugal impeller 30 and improving the exhaust effect of the small centrifugal impeller 30.

[0152] In some embodiments, referring to Figures 61, 62, and 63, a volute casing 19 is formed within the main body 11, and the miniature centrifugal impeller 30 is positioned within the volute casing 19. The ratio of the distance L1 between the outer circle (having a diameter D) formed by the outer edges 323 of each blade 321 and the volute tongue of the volute casing 19 and the diameter D of the outer circle is L1 / D. When L1 is small, the airflow is large but the noise level is relatively high (airflow impact is significant). Conversely, when L1 is large, the noise level is low but there is circulatory reflow, and the airflow level is also low. Therefore, the value of L1 / D is preferably in the range of 0.05 to 0.1, i.e., the value of the distance L1 is in the range of 0.05D to 0.1D. Meanwhile, the ratio of the outlet size L3 of the volute casing 19 to the diameter D of the outer circle is L3 / D, where the outlet size L3 is the distance from the side wall facing the volute tongue at the outlet of the volute casing 19 to the volute tongue. If L3 is small, the air outlet area will be small. Conversely, if L3 is large, the profile of the volute casing will be short, resulting in insufficient accumulation of pressure boost. Therefore, the value of L3 / D is preferably in the range of 0.8 to 1.2; that is, the value of the distance L3 will be in the range of 0.8D to 1.2D.

[0153] In some embodiments, referring to FIG. 64 , the air intake 15 has a mesh structure, for example, and the outer diameter D1 of the projected area on a plane perpendicular to the first direction is larger than the diameter d of the inner circle of the miniature centrifugal impeller 30 and smaller than the diameter D of the outer circle. In other words, the outer edge of the projected area of ​​the air intake 15 on a plane perpendicular to the first direction is located between the inner edge 324 and the outer edge 323 of each blade 321. In this way, the air intake area of ​​the miniature centrifugal impeller 30 can be effectively increased. Specifically, the normal design size of the air intake 15 of the miniature centrifugal impeller 30 is D1≦d. However, because the size of the miniature centrifugal impeller 30 is small, the air intake 15 needs to be enlarged to ensure sufficient air intake. However, the air intake 15 cannot be enlarged to D1≧D. This causes pressure to escape, preventing the wind pressure of the air blown out of the miniature centrifugal impeller 30 from increasing.

[0154] 65 to 70, an eleventh embodiment of the present application provides a miniature centrifugal impeller 30 that can be used in, for example, any one of the portable temperature control devices described in the first to eighth embodiments. Specifically, the miniature centrifugal impeller 30 includes a hub 31 and a plurality of fan blades 32 arranged to surround the hub 31. Metaphorically speaking, the miniature centrifugal impeller 30 is provided with a connecting disk 35 that surrounds and connects to the hub 31. The plurality of fan blades 32 are arranged on the connecting disk 35 at intervals along the circumferential direction of the connecting disk 35, thereby surrounding and fixedly connecting the plurality of fan blades 32 to the hub 31. In other embodiments, the plurality of fan blades 32 may be directly connected and fixed to the circumferential side of the hub 31. For clarity, the miniature centrifugal impeller 30 of this embodiment typically refers to a miniature windmill that takes in air in the axial direction, expels air in the radial direction, and uses centrifugal force to perform work and increase the pressure of the air.

[0155] As shown in Figure 67, the diameter of the inner circle enclosed by the inner edges 324 of the multiple fan blades 32 is d, and the diameter of the outer circle enclosed by the outer edges 323 of the multiple fan blades 32 is D. The ratio d / D of the inner circle diameter d to the outer circle diameter D is called the wheel diameter ratio (i.e., the ratio of the inner circle diameter to the outer circle diameter). After repeatedly optimizing the design and manufacturing samples for a miniature centrifugal impeller with an outer circle diameter D of less than 50 mm, the applicant of the present application found that by controlling the wheel diameter ratio d / D of the miniature centrifugal impeller 30 to a value range of 0.5 to 0.85 and controlling the chord length L of each fan blade 32 to a value range of 3.75 mm to 10.75 mm, it is possible to ensure the effective working area of ​​each fan blade 32, improve the wind pressure of the blown air when the miniature centrifugal impeller is operating, and effectively solve the problem of poor exhaust efficiency of miniature centrifugal fans. Here, the chord length L is defined as the linear distance between the inner edge 324 and the outer edge 323 of the fan blade 32 (i.e., the linear distance between the inner and outer edges). In some embodiments, each fan blade 32 has the same chord length L. The range of values ​​for the diameter D of the outer circle of the miniature centrifugal impeller 30 is, for example, 28 mm to 47 mm. More specifically, reducing the diameter ratio d / D increases the effective working area of ​​each fan blade 32. However, if the diameter ratio d / D is set too small—for example, less than 0.5—the inner space of the inner edge 324 of each fan blade 32 becomes too small. This results in an excessively small intake space for the miniature centrifugal impeller, resulting in insufficient intake air volume and adversely affecting the exhaust efficiency. On the other hand, the hub arrangement space becomes insufficient, complicating the hub structural design. Therefore, in the embodiments of the present application, the lower limit of the diameter ratio is set to 0.5, and the upper limit of the chord length is set to 10.75 mm. Conversely, increasing the diameter ratio d / D increases the internal space of the inner edge 324 of each fan blade 32, thereby increasing the air intake space of the mini-centrifugal impeller and achieving a larger intake volume. However, if the diameter ratio d / D is set too large, for example, greater than 0.85, the chord length of each fan blade becomes too short (for example, less than 3.75 mm), reducing the effective working area of ​​each fan blade. This reduces the wind pressure of the air blown out of the mini-centrifugal impeller and impacts the exhaust effect. Therefore, in the examples of this application, the upper limit of the diameter ratio is set to 0.85 and the lower limit of the chord length is set to 3.75 mm.

[0156] In some embodiments, the diameter ratio d / D of the miniature centrifugal impeller 30 is in the range of 0.6 to 0.8, which ensures the effective working area size of each fan blade 32, thereby improving the wind pressure of the air blown out of the miniature centrifugal impeller 30 and improving the exhaust effect of the miniature centrifugal impeller 30. In one preferred embodiment, the diameter ratio d / D of the miniature centrifugal impeller 30 is 0.7.

[0157] 70, in some embodiments, each fan blade 32 has the same height h in the axial direction of the hub 31, and the value of the ratio h / D of the height h to the diameter D of the outer circle is, for example, in the range of 0.2 to 0.5, i.e., the value of the height h is in the range of 0.2D to 0.5D. This value range is advantageous for designing a slim miniature centrifugal impeller 30, making it easy to apply to portable electronic devices. Furthermore, the value of the ratio h / D of the height h to the diameter D of the outer circle is in the range of 0.25 to 0.4, i.e., the value of the height h is in the range of 0.25D to 0.4D, preferably 0.3D.

[0158] In some embodiments, as shown in Figures 65, 66, and 68, the mini-centrifugal impeller 30 further includes a reinforcing rib 33, which is arranged at one end (also called the fan blade leading end) of the multiple fan blades 32 that is closest to the intake side of the mini-centrifugal impeller 30. The outermost edge 333 of the reinforcing rib 33 is flush with the outer edges 323 of the multiple fan blades 32 in the radial direction of the hub 31, or protrudes from the outer edges 323 of the multiple fan blades 32. In this way, the reinforcing rib 33 connects the leading ends of the fan blades 32 to prevent deformation of each fan blade 32, and by not covering the leading end surfaces of each fan blade 32, the area directly above each fan blade 32 also functions as an intake area, thereby increasing the intake area of ​​the entire mini-centrifugal impeller 30. 66, the inner surface of the reinforcing rib 33 is fixedly connected to the outer edges 323 of the plurality of fan blades 32, and the outermost edges 333 of the reinforcing rib 33 are located outside the outer edges 323 in the radial direction of the hub 31, i.e., the reinforcing rib 33 extends outward a non-zero distance from the outer edges 323 in the radial direction of the hub 31, so that the leading end surfaces of the fan blades 32 are not completely covered by the reinforcing rib 33. Also, in one embodiment, it can be seen from FIG. 70 that the upper surface of the reinforcing rib 33 (i.e., the surface adjacent to the intake side of the centrifugal blower 10) is flush with the leading end surfaces of the fan blades 32.

[0159] In some embodiments, as shown in Figures 65 and 67, the number of fan blades 32 on the same side of the connecting disk 35 is 25 or more and 35 or less, preferably 30 or 32. This design allows for rational control of the wind resistance and blown-out wind pressure of the mini-centrifugal impeller. A large number of fan blades 32 not only increases the weight of the mini-centrifugal impeller, but also increases wind resistance. A small number of fan blades 32 reduces wind resistance, but also reduces the effective working area of ​​the mini-centrifugal impeller as a whole, resulting in insufficient blown-out wind pressure.

[0160] In some embodiments, as shown in Figures 65 to 67, the curvature direction of each fan blade 32 extending from the inner edge 324 to the outer edge 323 is aligned with the rotation direction of the miniature centrifugal impeller 30. Correspondingly, the miniature centrifugal impeller 30 is a forward-inclined centrifugal impeller. A forward-inclined centrifugal impeller is advantageous for designing a compact centrifugal impeller, since the wind pressure of the air blown from the fan blades is large at low rotation speeds and a motor with a relatively small output can be selected.

[0161] In some embodiments, as shown in Figure 68, a cone-shaped structure is provided on the side of the hub 31 that is closest to the intake side of the miniature centrifugal impeller 30 (also called the front side of the hub). This cone-shaped structure functions as a guide structure to prevent the airflow from forming vortices at the intake port of the miniature centrifugal impeller 30, allowing the airflow to enter the interior of the miniature centrifugal impeller 30 more uniformly and reducing noise at the intake port.

[0162] In one embodiment, the miniature centrifugal impeller 30 is a one-piece molded structure, and the material used may be plastic, although the embodiment of the present application is not limited thereto.

[0163] To summarize the above, the small centrifugal impeller of this embodiment rationally controls the range of the diameter ratio d / D and the range of the chord length L of each fan blade, and specifies the parameters of the small centrifugal impeller so that the diameter is 0.5 to 0.85 and the chord length of the fan blade is 3.75 mm to 10.75 mm, thereby ensuring the effective working area size of each fan blade, thereby ensuring the wind pressure of the air blown out by the small centrifugal impeller and allowing the small centrifugal blower to have a high-quality exhaust effect.

[0164] 71, the centrifugal fan 3 provided in the twelfth embodiment of the present application includes a motor 36 and a small centrifugal impeller 30, and the motor 36 is mechanically coupled to the small centrifugal impeller 30. The specific structure of the small centrifugal impeller 30 of the centrifugal fan 3 in this embodiment can be referenced from the eleventh embodiment described above, for example, the related structures shown in FIGS. 65 to 70, and will not be repeated here.

[0165] As mentioned above, the motor 36 may be a single-phase two-wire motor or a three-phase three-wire motor, preferably a three-phase three-wire motor. A three-phase three-wire motor has lower power consumption, lower noise, and higher energy efficiency than a single-phase two-wire motor. The magnetic ring 361 (i.e., rotor) of the motor 36 is suitable for being housed within the hub 31 (see FIG. 66) of the miniature centrifugal impeller 30 and may be a rubber magnetic ring or a neodymium-iron-boron magnetic ring, preferably a neodymium-iron-boron magnetic ring. The neodymium-iron-boron magnetic ring is thinner than a rubber magnetic ring for the same magnetic flux, providing more space for the motor. This allows the motor to be configured as a three-phase three-wire motor and reduce power consumption. For example, a rubber magnetic ring typically has a thickness of more than 1 mm, while a neodymium-iron-boron magnetic ring can be less than 0.8 mm thick. More specifically, a single-phase two-wire motor generally refers to a low-power single-phase asynchronous motor powered by a single-phase AC power source. Such motors typically have two-phase windings on the stator, and the distribution and power supply conditions of the two-phase windings on the stator can differ, resulting in different starting and operating characteristics. A three-phase, three-wire motor has symmetrical three-phase windings on the stator, and the rotor is configured with fixed-polarity magnetic poles with the same number of poles as the stator windings. The fixed-polarity magnetic poles are generated by DC current connected to the magnetic pole excitation windings. When the symmetrical three-phase windings on the motor stator are connected to a symmetrical three-phase power supply and symmetrical three-phase current is applied, a rotating magnetic field with the same number of poles as the rotor is generated in the motor's air gap. The magnetic poles of the rotating field attract the rotor's magnetic poles according to the principle of opposite poles attracting each other, causing the motor to rotate at the same synchronous rotational speed.

[0166] Furthermore, an embodiment of the present application further provides a portable electronic device including, for example, a case and a centrifugal fan housed in the case. The centrifugal fan here can be the centrifugal fan 3 shown in FIG. 71, and its specific structure will not be repeated here. Portable electronic devices generally have a limited internal storage space in their housings, and therefore it is inevitable that they will adopt a centrifugal fan with a small centrifugal impeller to achieve functions such as blowing air and dissipating heat.

[0167] As shown in FIG. 72, a thirteenth embodiment of the present application provides a fan speed adjustment circuit that can be used in, for example, any one of the first to eighth embodiments of the portable temperature adjustment device to achieve a fan speed adjustment function. The fan speed adjustment circuit includes a power supply module 500, a pulse width modulation module 600, and a fan motor 36. The power supply module 500 includes a first output terminal. The power supply module 500 is used to output a fixed voltage through the first output terminal. The pulse width modulation module 600 is electrically connected to the power supply module 500. The pulse width modulation module 600 includes a second output terminal. The pulse width modulation module 600 is used to output a pulse width modulation signal through the second output terminal. The fan motor 36 includes a motor negative terminal, a motor positive terminal, and a motor control terminal. The motor negative terminal is grounded, the motor positive terminal is electrically connected to the first output terminal, and the motor control terminal is electrically connected to the second output terminal. The pulse width modulation signal is a PWM (Pulse Width Modulation) signal. The power supply module 500 is connected to the motor's positive pole and supplies a fixed voltage to the fan motor 36, eliminating the need for a separate boost circuit, simplifying circuit design and reducing circuit manufacturing costs. The pulse-width modulation module 600 outputs PWM signals with different duty cycles to achieve different rotation speeds for the fan motor 36. The voltage output from the power supply module 500 to the motor's positive pole remains constant (e.g., 5V), allowing for more accurate adjustment of the rotation speed, achieving stepless speed adjustment, and improving durability. The number of fan motors 36 in this embodiment may be one, two, or any other number, and is not limited to this embodiment. Multiple fan motors 36 may also be connected in parallel.

[0168] Referring to FIG. 73, the power supply module 500 may include, for example, a battery 510, a battery charge management chip 520, and a charge / discharge unit 530. The battery 510 includes a battery positive electrode and a battery negative electrode, and the battery negative electrode is grounded. The charge / discharge unit 530 is connected to the battery positive electrode and includes the first output terminal described above. The charge / discharge unit 530 is used to charge or discharge the battery 510. The battery charge management chip 520 is electrically connected between the battery positive electrode and the charge / discharge unit 530 and is used to step down the input current when charging the battery 510 and output it to the battery positive electrode, or to step up the input current when discharging the battery 510 and output it to the charge / discharge unit 530. More specifically, referring to FIG. 74, the charge / discharge unit 530 includes a charging socket USB1, a first field-effect transistor Q1, and a second field-effect transistor Q2. The charging socket USB1 is used to connect to an external power source. The source of the first field-effect transistor Q1 is electrically connected to the charging socket USB1, and the drain of the first field-effect transistor Q1 is electrically connected to the battery charging management chip 520. The drain of the second field-effect transistor Q2 is electrically connected to the drain of the first field-effect transistor Q1, and the source of the second field-effect transistor Q2 is electrically connected to the first output terminal. The battery charging management chip 520 may be, for example, an SW6206 type management chip. When charging the battery 510, current is input from the external power source via the charging socket USB1, passes through the first field-effect transistor Q1, and is input to the battery charging management chip 520. The current is stepped down by the battery charging management chip 520 and then input to the battery positive terminal B+. When discharging the battery 510, current is output from the battery positive terminal B+, is boosted by the battery charging management chip 520, and a constant voltage is output to the first output terminal via the source of the second field-effect transistor Q2, providing a constant voltage to the fan motor 36. 74, for example, a resistor R1 is connected between the charging / discharging unit 530 and the battery charging management chip 520. For example, an inductor L1 is connected between the battery charging management chip 520 and the battery 510.In this embodiment, the specific elements in the battery charging management chip 520 and the charging / discharging unit 530 are not described one by one. The design of the power supply module 500 can be set with reference to the specific circuit diagram shown in FIG. 74 or with reference to other power supplies that can provide a fixed voltage, and this embodiment is not limited thereto.

[0169] 73, in one embodiment, the pulse width modulation module 600 includes, for example, a pulse width modulation chip 610. The pulse width modulation chip 610 includes the second output terminal for outputting a pulse width modulation signal. For example, referring to FIG. 75, the pulse width modulation chip 610 is, for example, a PB-03 type chip, and pin 19 is the second output terminal, which can output a pulse width modulation signal to the motor control terminal of the fan motor 36.

[0170] Furthermore, the pulse width modulation chip 610 further includes a first input terminal, and the pulse width modulation module 600 further includes a voltage stabilization unit 620 electrically connected between the power supply module 500 and the first input terminal for providing a stable input voltage to the pulse width modulation chip 610. Specifically, as shown in FIG. 75, the third pin of the pulse width modulation chip 610 is the first input terminal.

[0171] For example, the circuit structure of the voltage stabilization unit 620, as shown in FIG. 76, specifically includes a first Schottky diode D3, a second Schottky diode D4, a voltage stabilization chip U4, a first capacitor C26, a second capacitor C25, and a third capacitor C24. The positive electrode of the first Schottky diode D3 is electrically connected to the positive electrode of the battery. The positive electrode of the second Schottky diode D4 is electrically connected between the charging / discharging unit 530 and the battery charging management chip 520. The negative electrode of the second Schottky diode D4 is electrically connected to the negative electrode of the first Schottky diode D3. The voltage stabilization chip U4 includes an input pin, an output pin, and a ground pin. The input pin of the voltage stabilization chip U4 is connected to the negative electrode of the first Schottky diode D3, the output pin of the voltage stabilization chip U4 is connected to the first input terminal of the pulse width modulation chip 610 (i.e., the third pin of the pulse width modulation chip 610 in FIG. 75), and the ground pin of the voltage stabilization chip U4 is grounded. One end of the first capacitor C26 is electrically connected to the input pin of the voltage stabilizing chip U4, and the other end is grounded. One end of the second capacitor C25 is electrically connected to the output pin of the voltage stabilizing chip U4, and the other end is grounded. The third capacitor C24 and the second capacitor C25 are connected in parallel. The first Schottky diode D3 and the second Schottky diode D4 may be, for example, 1N5819 type diodes, and the voltage stabilizing chip U4 may be, for example, an HT7533 type chip. The positive electrode of the second Schottky diode D4 is connected to the VOUTC pin, specifically between the resistor R1 and the charge / discharge unit 530 in FIG. 74.

[0172] More specifically, the pulse width modulation module 600 further includes a switch unit 630 for adjusting the pulse width modulation signal output from the pulse width modulation chip 610. The switch unit 630 has a first connection end and a second connection end, with the first connection end electrically connected to the pulse width modulation chip 610 and the second connection end grounded. Specifically, referring to FIG. 77, the first connection end of the switch unit 630 includes a first switch pin and a second switch pin, and the corresponding pulse width modulation chip 610 includes a first control pin and a second control pin. The first switch pin is connected to the first control pin, and the second switch pin is connected to the second control pin. The switch unit 630 further includes a first switch SW1 and a second switch SW2. The first switch is electrically connected between the first switch pin and the second connection end, and the second switch is electrically connected between the second switch pin and the second connection end. The pulse width modulation chip 610 is used to control the start and stop of the fan motor 36 according to the operation of the first switch. The pulse width modulation chip 610 is used to control the duty cycle of the pulse width modulation signal according to the operation of the second switch. Referring to FIGS. 75 and 77, pin 16 of the pulse width modulation chip 610 is connected to the first switch pin, and the first switch SW1 and the second switch SW2 are, for example, SW-PB2 type pushbutton switches. One end of the first switch SW1 is connected to pin 16 of the pulse width modulation chip 610 and the other end is grounded. Pin 31 of the pulse width modulation chip 610 is connected to the second switch pin, and one end of the second switch SW2 is connected to pin 31 of the pulse width modulation chip 610 and the other end is grounded. As shown in FIG. 77, the switch unit 630 further includes, for example, a resistor R26 disposed between the first switch pin and the first switch SW1, and a resistor R40 disposed between the second switch pin and the second switch SW2. In actual use, when it is necessary to start or stop the fan motor 36, the first switch SW1 is operated, and when it is necessary to adjust the rotation speed of the fan motor 36, the second switch SW2 is operated, so operation is easy.

[0173] 78, in one embodiment, the fan speed adjustment circuit further includes a motor protection unit connected in parallel between the motor positive pole and the motor negative pole of the fan motor 36. The motor protection unit includes a diode D2 and a protection capacitor C18, where the positive pole of the diode D2 is electrically connected to the motor negative pole and the negative pole of the diode D2 is electrically connected to the motor positive pole. The protection capacitor C18 and the diode D2 are connected in parallel between the motor positive pole and the motor negative pole. The motor protection unit consumes and recovers electrical energy generated when the fan motor 36 stops operating, thereby preventing damage to the fan motor 36.

[0174] Another embodiment of the present application provides a portable speed-adjustable fan including the fan speed adjustment circuit described in any of the above embodiments. This portable speed-adjustable fan further includes, for example, a casing for accommodating the fan speed adjustment circuit and fan blades fixed to the fan motor 36. Conventional methods for assembling portable fans can be referenced, and this embodiment is not limited thereto. By adopting the above fan speed adjustment circuit, the speed-adjustable fan's wind speed adjustment stepping can reach 1%, achieving a stepless speed adjustment effect, making speed adjustment more flexible and easier to use. Furthermore, there is no need for an additional boost circuit, significantly reducing costs.

[0175] 79 and 80, a fan assembly provided by a fourteenth embodiment of the present application may be, for example, the centrifugal blower of any one of the first to eighth embodiments. Specifically, the fan assembly includes an impeller 30, a motor 36, and a control chip 37. The motor 36 includes, for example, a stator 362 and a rotor 361. The rotor 361 is rotatable relative to the stator. The stator 362 includes at least two pairs of windings. The rotor 361 is disposed around the at least two pairs of windings and is connected to the impeller 30. The control chip 37 is electrically connected to the at least two pairs of windings. The control chip 37 is used to control the rotor 361 to rotate the impeller 30 by controlling changes in the magnetic fields in the at least two pairs of windings. The impeller 30 may include, for example, a hub 31 and fan blades 32 provided on the hub 31. The impeller 30 may further include, for example, a rotating shaft 38. The motor 36 may further include, for example, a rotating shaft mounting portion 34. A first end of the rotating shaft 38 is connected to the impeller 30, and a second end of the rotating shaft 38 is inserted into the rotating shaft mounting portion 34, and the second end of the rotating shaft 38 is rotatable relative to the rotating shaft mounting portion 34 within the rotating shaft mounting portion 34. The fan assembly may further include, for example, a fixed shaft. The fixed shaft may have, for example, a shaft hole. The rotating shaft mounting portion 34 is mounted within the shaft hole. The second end of the rotating shaft 38 rotates relative to the fixed shaft within the rotating shaft mounting portion 34.

[0176] The rotor 361 may be housed within the hub 31 of the impeller 30. The rotor 361 may be, for example, a rubber magnetic ring or a neodymium-iron-boron magnetic ring. Preferably, the rotor 361 is a neodymium-iron-boron magnetic ring. The neodymium-iron-boron magnetic ring is thinner than a rubber magnetic ring for the same magnetic flux, providing more space for the stator 362. This allows the stator 362 to be configured as a three-phase, three-wire motor, reducing power consumption. The thickness of the rubber magnetic ring is typically greater than 1 mm, while the thickness of the neodymium-iron-boron magnetic ring may be less than 0.8 mm. Preferably, the thickness of the rotor 361 provided in this embodiment is less than 0.8 mm.

[0177] 81 and 82, the stator 362 may further include, for example, a motor bracket 363. At least two pairs of windings are arranged on the motor bracket 363. The at least two pairs of windings may include, for example, two pairs of windings, each pair including a first winding 364 and a second winding 365. For example, the two pairs of windings may include, for example, one pair of main windings and one pair of secondary windings, where the one pair of main windings includes the first winding 364 and the second winding 365, and the one pair of secondary windings also includes the first winding 364 and the second winding 365. As shown in FIG. 81, the one pair of main windings and the one pair of secondary windings are arranged perpendicular to each other on the motor bracket 363, i.e., the two first windings 364 of the main winding and the secondary winding are arranged adjacent to each other, and the two second windings 365 of the main winding and the secondary winding are arranged adjacent to each other. The stator 362 may include, for example, a first winding wire 366 and a silicon steel plate 367. The motor bracket 363 may be provided with, for example, four winding portions 368. The first winding wire 366 may be, for example, an enameled wire. Enameled wire is one of the main types of winding wire and consists of two parts: a conductor and an insulating layer. It is made by annealing a bare wire to soften it, then painting it multiple times and baking it. The silicon steel plate 367, also known as an electrical steel plate or silicon steel plate (silicon steel billet), refers to a silicon-iron soft magnetic alloy with an extremely low carbon content (after annealing, the carbon content is 0.005% or less), generally with a silicon content of 0.5% to 4.5%. Adding silicon to iron can improve its electrical resistivity and maximum magnetic permeability. The silicon steel plate 367 may have, for example, multiple layers and be connected to the motor bracket 363. Portions of the silicon steel plate 367 may be wound around, for example, four winding portions 368 of the motor bracket 363. The outer side of the silicon steel plate 367 protrudes outside the motor bracket 363, and the inner side of the silicon steel plate 367 protrudes into an intermediate hole of the motor bracket 363. The rotating shaft mounting portion 34 is housed in the intermediate hole of the motor bracket 363 and is disposed spaced apart from the inner side of the silicon steel plate 367. The fixed shaft is clamped and fixed between the rotating shaft mounting portion 34 and the inner side of the silicon steel plate 367.The first winding wire 366 is wound around four winding portions 368 in order to form one pair of main windings and one pair of sub windings. That is, the four windings in the two pairs of windings are formed by winding one first winding wire 366, which corresponds to four windings connected in series. The winding directions of the first winding 364 and the second winding 365 are opposite to each other. The motor bracket 363 may be provided with, for example, at least two legs 369. Both ends of the first winding wire 366 are connected to the two legs 369, respectively.

[0178] Taking FIG. 83 as an example, the pair of main windings may include, for example, a first winding 364 and a second winding 365, and the pair of secondary windings may include, for example, a first winding 364 and a second winding 365. Position 1 is the first winding 364 of the pair of secondary windings, position 2 is the first winding 364 of the pair of main windings, position 3 is the second winding 365 of the pair of secondary windings, and position 4 is the second winding 365 of the pair of main windings. The winding direction of the first winding 364 of the pair of secondary windings may be, for example, counterclockwise, in which case the winding direction of the second winding 365 of the pair of secondary windings is clockwise, the winding direction of the first winding 364 of the pair of main windings is clockwise, and the winding direction of the second winding 365 of the pair of main windings is counterclockwise. Alternatively, for example, the winding direction of the first winding 364 of the pair of secondary windings may be clockwise, the winding direction of the second winding 365 of the pair of secondary windings may be counterclockwise, the winding direction of the first winding 364 of the pair of main windings may be counterclockwise, and the winding direction of the second winding 365 of the pair of main windings may be clockwise. Naturally, the winding directions of the first winding 364 and the second winding 365 can be adjusted according to the different positions at which the stator 362 is installed. When the motor 36 is connected to a power source, the input current is, for example, a single-phase sinusoidal current, and the pair of main windings generates an alternating pulsating magnetic field. The strength of the alternating pulsating magnetic field changes as the sinusoidal current changes over time. Taking the first winding 364 of the pair of main windings at Position 2 as an example, the magnetic field direction is, for example, from Position 1 to Position 3. The control chip 37 phase-shifts the injected single-phase sinusoidal current and then applies the phase-shifted current to a pair of secondary windings. Taking the first winding 364 of the pair of secondary windings at position 1 as an example, the magnetic field direction is, for example, from position 4 to position 2. After the motor 36 is connected to a power source, part of the single-phase sinusoidal current acts on the pair of main windings to supply power, and the other part is phase-shifted under the control of the control chip 37, and then the phase-shifted current acts on the pair of secondary windings to supply power. Because the phases of the single-phase sinusoidal current and the phase-shifted current are out of phase with each other, the magnetic field forces generated by the corresponding pair of main windings and pair of secondary windings are also out of phase with each other. In this way, the pair of main windings and pair of secondary windings sequentially generate thrust, rotating the rotor 361 and thus the impeller 30.By controlling the change in the magnetic field in the two pairs of windings with the control chip 37, the rotor 361 is controlled to rotate the impeller 30, so that the fan assembly has a higher and more stable rotation speed, further improving the performance of the fan assembly.

[0180] The circuit board 39 may be provided with, for example, a mounting groove 394, and the control chip 37 is disposed in the mounting groove 394. In this way, the thickness of the circuit board can be reduced, the assembly can be more compact, and the volume of the fan assembly can be further reduced. In addition, the distance between the control chip 37 and the two pairs of windings can be increased, thereby reducing the influence of the control chip 37 on the magnetic fields of the two pairs of windings. As can be understood, the circuit board 39 may further be provided with other elements, such as capacitors, resistors, and diodes, which will not be described one by one in this embodiment.

[0181] 85, 86, and 87, a specific embodiment of the fifteenth embodiment of the present application differs from the above-described fourteenth embodiment in that in this embodiment, at least two pairs of windings may be included, for example, three pairs of windings, and each pair of windings includes a first winding 364 and a second winding 365, and the first winding 364 and the second winding 365 are arranged opposite each other on the motor bracket 363. The stator 362 may include, for example, three second winding wires 370. The motor bracket 363 is provided with six winding portions 368. The second winding wire 370 may be, for example, an enameled wire. A silicon steel plate 367 is connected to the motor bracket 363, and a portion of the silicon steel plate 367 may be wound around the six winding portions 368 of the motor bracket 363, for example. Each second winding wire 370 is wound around two opposing winding portions 368 to form a pair of windings. The winding directions of the first winding 364 and the second winding 365 in each pair are opposite to each other, while the winding directions of three adjacent first windings 364 and three adjacent second windings 365 are the same. The motor bracket 363 may be provided with, for example, four legs 369. One ends of the three second winding wires 370 may be connected together, for example, by connecting one end of each of the three second winding wires 370 to the same leg 369. The other ends of the three second winding wires 370 are respectively connected to the other three legs 369. In this embodiment, the corresponding rotor 361 is provided with two pairs of magnetic poles. Naturally, the rotor 361 may be provided with one pair of magnetic poles or three pairs of magnetic poles, and the optimal solution is to provide two pairs of magnetic poles on the rotor 361. When the rotor 361 is provided with two pairs of magnetic poles, the stator 362 and the rotor 361 can cooperate better, making the rotation of the rotor 361 more stable and preventing the rotor 361 from being jammed due to the large number of magnetic poles on the rotor 361.

[0182] The three pairs of windings may be connected to, for example, a three-phase AC power source. Because the three-phase AC power source has a phase difference of 120°, when the three pairs of windings are connected to the three-phase AC power source, they generate a circular rotating magnetic field, driving the rotor 361 to rotate. In this way, the fan assembly's motor 36 can be started directly, requiring a small starting current, and the impeller 30 has a stronger rotational inertia than a single-phase motor, resulting in smoother rotation of the motor 36. Second, the motor 36 has a simple structure and does not require elements such as a starting capacitor or centrifugal switch; it generates a rotating magnetic field directly through three-phase AC induction. Furthermore, the motor 36 has a large operating force, allowing the fan assembly to rotate quickly and steadily with low noise. Furthermore, the motor 36 is relatively energy-efficient, resulting in a relatively energy-efficient fan assembly and improved durability.

[0183] Referring to FIGS. 88 and 89 , a sixteenth embodiment of the present application further provides a portable temperature control device. The portable temperature control device may be a neck fan, a waist fan, a head-mounted fan, a handheld fan, or the like. Hereinafter, taking a neck fan as an example, the portable temperature control device may include, for example, a main body 11 and the fan assembly of the above-described embodiment, where the fan assembly is disposed within the main body 11. The main body 11 surrounds and forms a wearing space 10. The main body 11 may be provided with, for example, a wearing part 130, which may be worn, for example, around the user's neck. The main body 11 may further be provided with an exhaust port 16, which may, for example, direct air blown from the fan assembly toward the user's cheeks. Naturally, this is merely an example, and the present embodiment is not limited thereto.

[0184] As can be seen from the above, the above technical features of the present application can achieve one or more of the following beneficial effects: The motor 36 in the fan assembly includes a stator 362 and a rotor 361 rotatable relative to the stator 362, the stator 362 including at least two pairs of windings, the rotor 361 being disposed around the at least two pairs of windings and connected to the impeller 30, i.e., the motor 36 in the fan assembly is an external rotor motor, which provides the following advantages: a large moment of inertia, good heat dissipation, reduced winding wire, and the impeller 30 and other load members can be directly connected to the rotor 361, meeting the overall installation size requirements of small-volume equipment; the motor 36 in the fan assembly has a simple structure and is relatively small in volume and weight, making the fan assembly more applicable to portable temperature adjustment devices. Furthermore, by configuring the control chip 37 to be connected to at least two pairs of windings on the stator 362, the control chip 37 can control the change in the magnetic field on the at least two pairs of windings, thereby controlling the rotor 361 to rotate the impeller 30. The control chip 37 can better control the rotation of the control motor 36, further improving the rotation effect of the fan assembly.

[0185] 90, a novel semiconductor cooler 700 provided in a seventeenth embodiment of the present application may be, for example, the temperature adjustment member of any of the above-mentioned first to eighth embodiments. Specifically, the semiconductor cooler 700 includes, for example, a first substrate 710, a second substrate 720, a packaging member 730, a plurality of thermocouples 740, and a temperature sensing unit 750.

[0186] Here, the packaging member 730 is disposed between the first substrate 710 and the second substrate 720, and the packaging member 730, together with the first substrate 710 and the second substrate 720, surrounds and forms an accommodating space 760. The plurality of thermocouples 740 and the temperature sensing unit 750 are, for example, both disposed between the first substrate 710 and the second substrate 720 and positioned inside the accommodating space 760.

[0187] Furthermore, the semiconductor cooler 700 further includes, for example, a first terminal 770 and a second terminal 780. The first terminal 770 is electrically connected to the plurality of thermocouples 740 and extends to the outside of the accommodating space 760, and the second terminal 780 is electrically connected to the temperature sensing unit 750 and extends to the outside of the accommodating space 760. Specifically, the first terminal 770 includes, for example, a first connecting line 772 and a second connecting line 774, and the second terminal 780 includes, for example, a third connecting line 782 and a fourth connecting line 784. For example, the first connecting line 772 and the second connecting line 774 are power lines, and the third connecting line 782 and the fourth connecting line 784 are signal lines. The first connecting wire 772 and the second connecting wire 774 are electrically connected to the plurality of thermocouples 740 and extend outside the accommodating space 760 for electrical connection to an external circuit. The third connecting wire 782 and the fourth connecting wire 784 are electrically connected to the temperature sensing unit 750 and extend outside the accommodating space 760 for electrical connection to an external circuit. To easily distinguish the first terminal 770 and the second terminal 780, the first terminal 770 and the second terminal 780 may use wires of different thicknesses or colors. For example, the first connecting wire 772 and the second connecting wire 774 may use thin wires, and the third connecting wire 782 and the fourth connecting wire 784 may use thick wires. Alternatively, the first connecting line 772 and the second connecting line 774 may be white and blue, respectively, and the third connecting line 782 and the fourth connecting line 784 may be black and red, respectively. In other embodiments, the first terminal 770 and the second terminal 780 may be connected in other ways as long as the plurality of thermocouples 740 and the temperature sensing unit 750 can be connected to an external circuit, respectively.

[0188] As shown in FIG. 92, each thermocouple 740 includes, for example, a first-type semiconductor thermocouple 742 and a second-type semiconductor thermocouple 744 connected in series. The first-type semiconductor thermocouple 742 is, for example, an N-type semiconductor thermocouple, and the second-type semiconductor thermocouple 744 is, for example, a P-type semiconductor thermocouple, or vice versa. Because the carriers in an N-type semiconductor thermocouple are electrons and the carriers in a P-type semiconductor thermocouple are holes, the current directions in the different types of semiconductor thermocouples are opposite. Therefore, the electrons in the N-type semiconductor thermocouple and the holes in the P-type semiconductor thermocouple flow in the same direction. The carriers in the semiconductor thermocouple act as a medium for heat transfer, and an external DC power source provides the energy required for the electron flow. When the power is turned on, electrons start from the negative pole (-) and first pass through the P-type semiconductor thermocouple, absorbing heat and then releasing it when they reach the N-type semiconductor thermocouple. Each time it passes through a pair of N-type and P-type semiconductor thermocouples, hot air is sent from one end to the other. This active pumping of hot air creates a temperature difference, forming a cold end. When the current direction is reversed, the hot air transfer direction is also reversed. Temperature control can be performed using this principle. The temperature sensing unit 750 senses the operating temperature of the semiconductor cooler 700, obtains the sensing result, and outputs the sensing result to an external circuit.

[0189] For example, the external circuit mentioned above is an external control circuit, and the multiple thermocouples 740 are electrically connected to the external control circuit via the first connecting line 772 and the second connecting line 774 to realize cold-end cooling and hot-end heating. The temperature sensing unit 750 is electrically connected to the external control circuit via the third connecting line 782 and the fourth connecting line 784 to sense the operating temperature of the semiconductor cooler 700 and send the sensing result to the external control circuit. When the operating temperature exceeds a set value, a controller of the external control circuit can adjust the heat dissipation efficiency of the semiconductor cooler 700 or directly turn off the semiconductor cooler 700 to protect the semiconductor cooler 700 from damage.

[0190] In the embodiment of the present application, a first substrate 710, a second substrate 720, and a packaging member 730 are provided to surround and form an accommodating space 760, thereby isolating the accommodating space 760 from the external environment. The packaging member 730 serves to provide moisture protection and heat insulation. By integrating the temperature sensing unit 750 within the accommodating space 760, i.e., by having the temperature sensing unit 750 within the solid-state cooler 700, there is no need to install a separate temperature sensing unit. This not only prevents the temperature sensing unit 750 from falling off the solid-state cooler 700 due to external forces or other factors, as in the prior art, but also prevents the influence of environmental temperature on the temperature detection process, thereby enabling more accurate detection of the operating temperature of the solid-state cooler 700. Furthermore, the temperature sensing unit 750 is integrated and arranged inside the semiconductor cooler 700, and the temperature detected by the temperature sensing unit 750 is not the operating temperature of the part of the outer surface of the semiconductor cooler 700 that is in close contact with the semiconductor cooler 700, but the operating temperature inside the semiconductor cooler 700. This allows the temperature change during operation of the semiconductor cooler 700 to be more accurately reflected, thereby further improving the detection accuracy of the operating temperature of the semiconductor cooler 700.

[0191] The structure of the semiconductor cooler 700 will be further described below with reference to the accompanying FIGS.

[0192] Referring again to FIG. 90, the first substrate 710 and the second substrate 720 are disposed, for example, facing each other. For example, the first substrate 710 and the second substrate 720 are disposed, for example, parallel to each other. The first substrate 710 is, for example, a cold-end substrate, and the second substrate 720 is, for example, a hot-end substrate, or vice versa. The first substrate 710 and the second substrate 720 can be fixedly connected to each other via a packaging member 730. The packaging member 730 is, for example, filled in the peripheral portion between the first substrate 710 and the second substrate 720 to maintain the stability of the connection between them. For example, rubber can be selected and used as the packaging member 730. After hardening, the rubber becomes a milky-white elastic solid. The purpose of hardening is to isolate the plurality of thermocouples 740 and the temperature sensing unit 750 from the external environment and to provide moisture and heat insulation. Furthermore, the first substrate 710 and the second substrate 720 are ceramic substrates, such as substrates made of materials such as Al2O3 (aluminum oxide), BeO (bismuth oxide), and AlN (aluminum nitride). This provides excellent thermal conductivity and electrical insulation, simplifying the structure of the semiconductor cooler 700 while ensuring operational performance. In one specific embodiment, one or both of the first substrate 710 and the second substrate 720 may be, for example, a metal substrate, with an insulating layer formed on the inner surface of the metal substrate. For example, the metal substrate may be an aluminum substrate, a copper substrate, or another metal conductor. The positions where the inner surfaces of the first substrate 710 and the second substrate 720 contact the multiple thermocouples 740 are separated by an insulating layer. This ensures electrical isolation between the current flowing through the multiple thermocouples 740 and the first and second substrates 710 and 720, and also makes it possible to fully utilize the superior thermal conductivity of the first and second substrates 710 and 720, which are made of metal, to conduct the cold and hot air generated by the multiple thermocouples 740 to the outside.

[0193] As described above, the plurality of thermocouples 740 are, for example, fixedly sandwiched between the first substrate 710 and the second substrate 720 and sequentially connected in series between the first connecting wire 772 and the second connecting wire 774, as shown in FIG. 91 . The number of the plurality of thermocouples 740 is preferably 100 to 120, and more preferably 103 or 105. This allows the semiconductor cooler 700 to provide sufficient cool or hot air and improve the user experience when applied to a portable product. Referring to FIG. 92 , each of the thermocouples 740 includes, for example, a first type of semiconductor thermocouple 742 and a second type of semiconductor thermocouple 744 connected in series. Each of the first type of semiconductor thermocouple and the second type of semiconductor thermocouple has a height H1 of 1.0 mm to 2.0 mm in the distance direction between the first substrate and the second substrate. The height H1 is preferably 1.7 mm, which is advantageous for reducing the thickness of the semiconductor cooler 700 and is more suitable for portable products.

[0194] Furthermore, it is preferable that the length and width of the first type semiconductor thermocouple 742 and the second type semiconductor thermocouple 744 of each of the thermocouples 740 are both 1.0 mm. The distance between the first type semiconductor thermocouple 742 and the second type semiconductor thermocouple 744 of each of the thermocouples 740 is 0.5 mm to 1.2 mm. Referring to FIG. 92, there is a first distance D1 between the first type semiconductor thermocouple 742 and the second type semiconductor thermocouple 744 of a first thermocouple of two adjacently arranged thermocouples 740, and there is a second distance D2 between the first type semiconductor thermocouple 742 and the second type semiconductor thermocouple 744 of a second thermocouple of the two adjacently arranged thermocouples 740, and the second distance D2 is different from the first distance D1. For example, the first distance D1 is, for example, 0.5 mm to 0.7 mm, and the first distance D1 is preferably 0.6 mm, and the second distance D2 is, for example, 0.8 mm to 1.2 mm, and the second distance D2 is preferably 1.0 mm. Here, by setting the first distance D1 and the second distance D2 to be different and further designing the ranges of the values ​​of the first distance D1 and the second distance D2, the semiconductor cooler 700 can have a better cooling or heating effect.

[0195] 90 and 91 , the temperature sensing unit 750 is disposed in an edge region between the first substrate 710 and the second substrate 720, which is located outside the arrangement region of the plurality of thermocouples 740. The arrangement region of the plurality of thermocouples 740 may refer to an area formed by spreading outward from the center between the first substrate 710 and the second substrate 720. In this way, on the one hand, the arrangement of the plurality of thermocouples 740 is not affected even when the temperature sensing unit 750 is additionally disposed inside the semiconductor cooler 700, and on the other hand, the third connection line 782 and the fourth connection line 784 of the temperature sensing unit 750 can be easily drawn out to the outside, thereby simplifying the manufacturing process of the semiconductor cooler 700.

[0196] Furthermore, the temperature sensing unit 750 is, for example, attached to the inner surface of the first substrate 710, thereby simplifying the installation of the temperature sensing unit 750 inside the solid-state cooler 700. For example, the temperature sensing unit 750 includes, for example, a thermosensitive resistor. When the temperature sensing unit 750 detects the internal temperature of the solid-state cooler 700 as the operating temperature of the solid-state cooler 700, the external circuit can optimize the control curve for the solid-state cooler 700 according to the detection result of the temperature sensing unit 750, thereby improving the accuracy of temperature control for the solid-state cooler 700. Furthermore, when the internal operating temperature of the solid-state cooler 700 is too high, a protection control for the solid-state cooler 700 can be timely activated, thereby extending the service life of the solid-state cooler 700 and thereby avoiding safety risks caused by overheating of the solid-state cooler 700.

[0197] In summary, the novel semiconductor cooler provided in the seventeenth embodiment of the present application isolates the accommodating space from the external environment by providing a first substrate, a second substrate, and a packaging member surrounding the accommodating space. The packaging member serves to protect against moisture and heat. By integrating the temperature sensing unit within the accommodating space, i.e., by having the temperature sensing unit within the semiconductor cooler, a separate temperature sensing unit is not required. This not only avoids the problem of the temperature sensing unit falling off the semiconductor cooler due to external forces or other factors, but also avoids the influence of environmental temperature on the temperature detection process, thereby enabling more accurate detection of the operating temperature of the semiconductor cooler. Furthermore, by integrating the temperature sensing unit within the semiconductor cooler and detecting the temperature within the semiconductor cooler rather than the operating temperature at a location on the semiconductor cooler's outer surface, temperature changes during operation can be more accurately reflected, thereby further improving the accuracy of detecting the operating temperature of the semiconductor cooler. Furthermore, by setting the first distance and the second distance between the first type of semiconductor thermocouple and the second type of semiconductor thermocouple to be different, the semiconductor cooler can have a better cooling or heating effect. Furthermore, by designing the number of thermocouple pairs, sufficient cool or hot air can be provided when applied to a portable product, improving the user experience. Furthermore, by designing the height of the first type of semiconductor thermocouple and the second type of semiconductor thermocouple, it is advantageous to make the semiconductor cooler thinner, making it more suitable for portable products.

[0198] 93 and 94, a portable temperature control device provided in an eighteenth embodiment of the present application includes a main body 11, the semiconductor cooler 700 described in the seventeenth embodiment above, which is provided within the main body 11, and a temperature-conducting member 2 provided inside the main body 11. The temperature-conducting member 2 is thermally connected to the first substrate 710 of the semiconductor cooler 700. The portable temperature control device may be a temperature control product that can be worn on different parts of a user's body. Accordingly, the main body 11 may refer to a structure for stably wearing the portable temperature control device on a corresponding part of the user's body. For example, the portable temperature control device may be a temperature control device worn on a user's wrist, and the main body 11 may refer to a wristband that surrounds the user's wrist. The portable temperature control device may be a temperature control device worn on a user's waist, and the main body 11 may refer to a fastening belt that surrounds the user's waist. The portable temperature control device may be a temperature control device worn around the neck of a user, and the main body 11 may be a neck-worn frame that is placed around the user's neck. In this embodiment, for ease of understanding, a neck-worn temperature control device will be described as an example of the portable temperature control device.

[0199] In some embodiments, the main body 11 includes a first arm 13a, a second arm 13b, and a connection structure 400 that flexibly connects the first arm 13a and the second arm 13b. The semiconductor coolers 700 are provided inside the first arm 13a and the second arm 13b, respectively, and the temperature conduction members 2 are provided inside the first arm 13a and the second arm 13b, respectively.

[0200] 95, in some embodiments, a positioning structure 800 for attaching and fixing the semiconductor cooler 700 may be provided inside the first arm portion 13a and the second arm portion 13b. The inside refers to the side that is relatively close to the skin surface of the user's body when the portable temperature adjustment device is worn on the user's body.

[0201] 94, in some embodiments, the connection structure 400 includes an elastic member 410 and two connecting members 420. The two connecting members 420 are connected to be rotatable relative to each other, and the connecting members 420 are connected to the first arm portion 13a and the second arm portion 13b, respectively. Both ends of the elastic member 410 can abut against the two connecting members 420, respectively, and apply an elastic force that rotates the first arm portion 13a and the second arm portion 13b inward via the connecting members 420, thereby maintaining a state in which the temperature conducting member 2 located inside the first arm portion 13a and the second arm portion 13b is in close contact with the skin of the neck when the neck-worn temperature regulator is worn around the neck of a user.

[0202] 93 and 94 , in some embodiments, the first arm portion 13a and the second arm portion 13b are provided with an intake port 15 and an exhaust port 16, respectively, and the first arm portion 13a and the second arm portion 13b are provided with an accommodating cavity 150 communicating with the intake port 15, and an air duct 17 communicating between the accommodating cavity 150 and the exhaust port 16. The first arm portion 13a and the second arm portion 13b may further include a fan wheel 3 accommodated in the accommodating cavity 150, respectively. The air duct 17 may be formed by partitioning a plurality of sub-air ducts 177 by partition members 138, and the exhaust ports 16 in the first arm portion 13a and the second arm portion 13b may be formed as a plurality of sub-exhaust ports corresponding to different sub-air ducts 177. In some embodiments, the internal spaces of the first arm portion 13a and the second arm portion 13b may be partitioned by a partition member 138 and may further include a receiving cavity 133 separated from the air duct 17. An external control circuit for the semiconductor cooler 700 may be disposed in the receiving cavity 133. Airflow generated during operation of the fan wheel 3 mainly flows into each sub-air duct 177 and, through the branching and guiding of the sub-air duct 177, flows out of the corresponding sub-exhaust ports 16, blowing air onto different parts of the human body for heat dissipation. A small portion of the airflow flows into the receiving cavity 133 to dissipate heat from the circuit, thereby ensuring the stability of the circuit during operation.

[0203] 96, in one specific embodiment, the length L1 of the semiconductor cooler 700 is 30 mm to 45 mm, and the width W1 of the semiconductor cooler 700 is 15 mm to 25 mm, and the size of the semiconductor cooler 700 is preferably such that the length L1 is 40 mm and the width W1 is 20 mm. In this way, on the premise of ensuring the cooling / heating effect of the semiconductor cooler 700 as much as possible, the semiconductor cooler can be made smaller, and the cooling / heating efficiency of the semiconductor cooler 700 can be improved with the same volume, making it applicable to small, portable products.

[0204] Referring again to FIG. 96, in some embodiments, the ratio of the length L1 of the semiconductor cooler 700 to the length L2 of the temperature conduction member 2 is 0.25 to 0.5, preferably 0.3. The ratio of the width W1 of the semiconductor cooler to the width W2 of the temperature conduction member is 0.5 to 0.75, preferably 0.6. The temperature conduction member 2 has two edges 331 facing each other along its length. The distance D3 to either edge 331 of the semiconductor cooler 700 along the length of the temperature conduction member 2 is 15 mm to 30 mm. By rationally designing the size relationship between the semiconductor cooler 700 and the temperature conduction member 2, the conduction efficiency and conduction uniformity of the temperature conduction member 2 can be ensured.

[0205] To summarize, the portable temperature regulating device provided in the seventeenth embodiment of the present application has more accurate temperature monitoring of the semiconductor cooler, better temperature regulating performance of the product, and can ensure the conduction efficiency and conduction uniformity of the temperature conduction member by rationally designing the size relationship between the semiconductor cooler and the temperature conduction member.

[0206] 97 to 99, the portable temperature control device provided in the 19th embodiment of the present application is worn on the human body, for example, on the neck, waist, abdomen, etc., to achieve a cooling or warming effect. The following description will be given taking the case of wearing it on the neck as an example.

[0207] The portable temperature adjustment device of this embodiment will be compared with the portable temperature adjustment device of the first embodiment. In this embodiment, the portable temperature adjustment device includes a main body 11 and a plurality of temperature adjustment units. The main body 11 is used to be worn around the user's neck, and the plurality of temperature adjustment units are respectively attached to the main body 11 and used to adjust the temperature to achieve a cooling or warming effect. A cavity body 178 for accommodating the temperature adjustment units is provided inside the main body 11. As can be understood, the temperature adjustment units may be completely accommodated within the cavity body 178, or may be partially accommodated within the cavity body 178 and partially located outside the cavity body 178.

[0208] The specific manner in which the main body 11 is worn around the neck is not limited, and for example, it can be worn directly around the user's neck, from the top of the head downward. Furthermore, the main body 11 can be arranged so that the two ends thereof can move relative to each other, so that the user can adjust the distance between the two ends of the main body 11 and wear the portable temperature control device directly around the neck in a horizontal insertion manner. In this embodiment, the two ends of the main body 11 can move relative to each other and the portable temperature control device can be worn around the neck in a horizontal insertion manner, so that the portable temperature control device is not affected by the head while being worn, allowing the portable temperature control device to be made smaller, and at the same time, making it easier to wear and remove the portable temperature control device.

[0209] The specific shape of the main body 11 is not limited, and examples thereof include a U-shape, a C-shape, and a ring shape. In this embodiment, the main body 11 has a ring-shaped structure, and the ring may be an unclosed ring or a closed ring. Compared to shapes such as a U-shape or a C-shape, a ring shape has a relatively small or no distance between its two ends, making the portable temperature control device less likely to fall off after being worn around the neck, reducing the risk of the portable temperature control device falling off the user's neck during exercise.

[0210] The main body 11 includes two arm portions 13 and a connecting member 1021, and each arm portion 13 is provided with a temperature adjustment unit, and the two arm portions 13 are connected to both ends of the connecting member 1021. Each arm portion 13 is provided with a cavity body 178 for accommodating the temperature adjustment unit.

[0211] There is no specific limit to the number of temperature adjustment units attached to each arm portion 13, and it may be one or more. In this embodiment, the number of temperature adjustment units is two, and each arm portion 13 is provided with one temperature adjustment unit.

[0212] In some embodiments, the other ends of the arm portions 13 remote from the connecting member 1021 can move relative to each other, so that during the process of putting on or taking off, the user can first move the ends of the two arm portions 13 remote from the connecting member 1021 in opposite directions to make the notch between the two ends larger than the width of the neck, allowing the neck to pass through the notch between the two ends.

[0213] The specific manner in which the ends of the two arms 13 remote from the connecting member 1021 can move relative to each other is not limited. For example, the two arms 13 can be rotatably connected to the connecting member 1021, and the distance between the two ends can be adjusted by rotating the two arms 13. Alternatively, the connecting member 1021 can be made elastic and deformable, so that the two arms 13 can move relative to each other by compressing or expanding the connecting member 1021. In this embodiment, the connecting member 1021 is deformable.

[0214] The specific type of connecting member 1021 is not limited, and may be, for example, a deformable silicone rubber member or an expandable flexible tube. In this embodiment, connecting member 1021 is a silicone rubber member. Silicone rubber members are elastic and deformable. When the two arms 13 receive an outward force, the ends of the two arms 13 that are farther away from connecting member 1021 move in opposite directions, pulling the silicone rubber member.

[0215] The main body 11 further includes a fixing sheet 179. The two arm portions 13 and the connecting member 1021 are all connected to the fixing sheet 179.

[0216] In some embodiments, the fixing sheet 179 has an elastic return function. When a user drives the ends of the two arms 13 away from the connecting member 1021 to move in opposite directions, the fixing sheet 179 deforms and moves together with the two arms 13. After the user releases the two arms 13, the ends of the two arms 13 away from the connecting member 1021 move toward each other under the action of the fixing sheet 179, eventually restoring the main body 11 to its original state, achieving an automatic return effect, i.e., returning to a ring shape, and preventing the portable temperature control device from falling off the user's neck.

[0217] There are no specific limitations on the material of the fixing sheet 179, and as long as it has an elastic return effect, it may be, for example, an elastic metal sheet, an elastic plastic sheet, etc. In this embodiment, the fixing sheet 179 is an elastic metal sheet.

[0218] Please refer to Figures 99 and 100. Each temperature adjustment unit includes a first fan 53, which is located in a cavity body 178. The main body 11 is provided with a first air intake 114 and a first air exhaust 101, which are both connected to the cavity body 178. When the first fan 53 is activated, it draws air from outside the portable temperature adjustment device into the cavity body 178 through the first air intake 114, and then, when activated, blows the air out of the first air exhaust 101 toward the user, thereby providing a cooling effect to the user.

[0219] The specific type of the first fan 53 is not limited, and may be, for example, an axial fan or a centrifugal fan. In this embodiment, the first fan 53 is a centrifugal fan. The first air intake port 114 is disposed on a radial side of the main body 11 (i.e., on the inside close to the user's neck or on the outside away from the user's neck), and the first air exhaust port 101 is disposed on an axial side of the main body 11. Specifically, the first air intake port 114 is provided on both the fixing sheet 179 and the side of the arm 13 away from the fixing sheet 179, and the first air exhaust port 101 is disposed on the axial side of the arm 13. By providing two first air intake ports 114, the intake volume can be increased, allowing more air to enter the cavity body 178 through the first air intake port 114, improving the air-blow cooling effect of the first fan 53.

[0220] The specific shapes of the first exhaust port 101 and the first intake port 114 are not limited, and may be, for example, through holes provided in the main body 11, or through grooves provided in the main body 11.

[0221] Each temperature adjustment unit further includes a second fan 54 and a temperature adjustment assembly 50. The second fan 54 is located within the cavity body 178. The main body 11 is provided with a second air intake 115, a second exhaust 113, and a heat dissipation vent 118, which communicate with the cavity body 178. A first exhaust path 57 is formed between the second fan 54 and the heat dissipation vent 118, and a second exhaust path 58 is formed between the second fan 54 and the second exhaust vent 113. The temperature adjustment assembly 50 includes a temperature adjustment member 4 located in the first exhaust path 57 and a temperature conduction member 2 connected to the temperature adjustment member 4. The temperature conduction member 2 is located at least partially outside the cavity body 178 so as to come into contact with the user. Specifically, the temperature conduction member 2 is located inside the arm portion 13. When the second fan 54 is activated, air from outside the portable temperature control device is drawn into the cavity body 178 through the second air intake 115. Then, as the second fan 54 is activated, some of the air enters the first exhaust path 57, flows through the temperature control member 4 of the temperature control assembly 50, and absorbs heat from the temperature control member 43 before being discharged through the heat dissipation port 118. Some of the air enters the second exhaust path 58 and is finally discharged through the second exhaust port 113, blowing toward the user, creating a cooling effect. Both the first fan 53 and the second fan 54 generate a cooling effect, increasing the cooling range of the portable temperature control device. The temperature control member 4 can generate both a cold flow and a heat flow. The temperature conduction member 2 contacts the user and transfers the cold or heat flow to the user, providing contact cooling or heating, i.e., a temperature control effect. When cooling the user, a cold flow is generated on the side of the temperature adjustment member 4 connected to the temperature conduction member 2, and is transmitted to the user via the temperature conduction member 2. A heat flow is formed on the side of the temperature adjustment member 4 away from the temperature conduction member 2. As the air in the first exhaust path 57 moves toward the heat dissipation port 118, it flows through the temperature adjustment member 4, removing the heat flow from the temperature adjustment member 4 and ensuring the cooling effect of the temperature adjustment member 4. The second blower 54 dissipates heat from the temperature adjustment member 4 and also provides a cooling effect to the user by blowing air, thereby improving the cooling effect of the multifunctional temperature adjustment device.

[0222] The fixing sheet 179 is provided with a first air intake 114, a second air intake 115, and a heat dissipation vent 118 corresponding to each temperature adjustment unit. Specifically, there are two temperature adjustment units, and the two temperature adjustment units are respectively arranged on two arm portions 13, and each temperature adjustment unit includes one first fan 53 and one second fan 54. The fixing sheet 179 is provided with a first air intake 114 corresponding to the two first fans 53, and with a second air intake 115 and a heat dissipation vent 118 corresponding to the two second fans 54.

[0223] The specific method for attaching the fixing sheet 179 is not limited, and it may be located inside or outside the main body 11. In this embodiment, the main body 11 is arranged to surround the mounting cavity, and the mounting cavity is located inside the main body 11. The main body 11 is attached to the user's neck via the mounting cavity. Mounting openings 182 that communicate with the cavity body 178 are provided on the sides of the two arms 13 and the connecting member 1021 away from the mounting cavity, and these mounting openings 182 communicate with the cavity body 178 and the outside of the main body 11. That is, the arms 13 and the connecting member 1021 are arranged to open radially outward, and the fixing sheet 179 is fitted into the mounting openings 182. By forming an attachment opening 182 on the outside of the main body 11 and fitting the fixing sheet 179 into the attachment opening 182, the fixing sheet 179 has a restoring effect and also has the effect of covering the cavity body 178 to protect the internal components, which is advantageous in reducing the volume and weight of the entire portable temperature control device. Specifically, the outer surface of the fixing sheet 179 is flush with the outer surfaces of the arm 13 and the connecting member 1021, reducing the sharpness of the fixing sheet 179.

[0224] The specific type of the second fan 54 is not limited, and may be, for example, an axial fan or a centrifugal fan. In this embodiment, the second fan 54 is a centrifugal fan, and the second air inlet 115 and the heat dissipation outlet 118 are arranged on a radial side (i.e., inside or outside) of the main body 11, and the second air outlet 113 is arranged on an axial side of the main body 11. Specifically, the second air inlet 115 and the heat dissipation outlet 118 are both arranged on the fixing sheet 179, and the second air outlet 113 is arranged on one axial side of the arm 13, on the same side of the main body 11 as the first air outlet 101. When the portable temperature control device is worn around the neck, the fixing sheet 179 is located away from the neck. Therefore, by arranging the heat dissipation outlet 118 on the fixing sheet 179, it is possible to prevent hot air discharged from the heat dissipation outlet 118 from blowing toward the user and affecting the cooling effect.

[0225] The specific shapes of the second exhaust port 113, the second intake port 115 and the heat dissipation port 118 are not limited, and may be, for example, a through hole provided in the main body portion 11 or a through groove provided in the main body portion 11.

[0226] In some embodiments, filters may be provided in the first air intake 114 and the second air intake 115 to filter the air entering the cavity body 178 and prevent dust in the outside air from entering the cavity body 178.

[0227] As shown in FIG. 100 , in this embodiment, a partition member 138 is provided in a cavity body 178 of the main body 11, and the partition member 138 separates the first exhaust path 57 and the second exhaust path 58 within the cavity body 178. Specifically, the first exhaust path 57 and the second exhaust path 58 are located on the same side of the second fan 54 and extend along the length of the arm 13. The partition member 138 separates the first exhaust path 57 and the second exhaust path 58, preventing the air in the two exhaust paths from circulating with each other. This prevents hot air generated after cooling the temperature adjustment member 4 in the first exhaust path 57 from flowing into the second exhaust path 58 and affecting the cooling effect of the second fan 54. In other embodiments, the partition member 138 may not be provided within the cavity body 178. For example, if the first exhaust path 57 and the second exhaust path 58 are not on the same side of the second blower 54, the air flows in different directions through the first exhaust path 57 and the second exhaust path 58, and the air in the two exhaust paths does not affect each other, so there is no need to provide a partition member 138 to separate them.

[0228] 99, the first fan 53 and the second fan 54 located within the same arm portion 13 are located at both ends of the arm portion 13, that is, one of the first fan 53 and the second fan 54 is located at one end of the arm portion 13 close to the connecting member 1021, and the other is located at one end of the arm portion 13 away from the connecting member 1021. The first exhaust port 101 extends from the first fan 53 toward the second fan 54 along the length direction of the arm portion 13 (in this embodiment, the circumferential direction of the main body portion 11), and the second exhaust port 113 extends from the second fan 54 toward the first fan 53 along the length direction of the arm portion 13 (in this embodiment, the circumferential direction of the main body portion 11). By placing the first fan 53 and the second fan 54 at both ends of the arm portion 13, respectively, the length of the first exhaust port 101 and the second exhaust port 113 in the longitudinal direction of the arm portion 13 can be made longer, thereby allowing the first fan 53 and the second fan 54 to provide a cooling effect by blowing air to more parts of the user's neck.

[0229] 102, compared to the aforementioned 19th embodiment, in this embodiment, the first fan 53 and the second fan 54, which are located within the same arm unit 13, are arranged in the middle region of the arm unit 13, the second fan 54 is closer to the connecting member 1021 than the first fan 53, and the exhaust directions of the first fan 53 and the second fan 54 are opposite. The first exhaust port 101 extends in a direction away from the connecting member 1021 along the length of the arm unit 13, the second exhaust port 113 extends from the second fan 54 toward the connecting member 1021 along the length of the arm unit 13, and the first exhaust path 57, the second exhaust path 58, and the partition member 138 are located between the second fan 54 and the connecting member 1021.

[0230] As shown in FIG. 100 , in this embodiment, the second fan 54 is disposed at one end of the arm 13 closest to the connecting member 1021, and the end of the arm 13 closest to the connecting member 1021 protrudes outward along the width direction of the arm 13 to form a protrusion 12 for accommodating the second fan 54. In this embodiment, the size of the second fan 54 in the width direction of the arm 13 is larger than the size of the first fan 53. When the portable temperature control device is worn around the neck, the connecting member 1021 and its surrounding area are positioned behind the user's neck, and due to the action of gravity, the inside of the connecting member 1021 and its surrounding area automatically adheres to the back of the user's neck. Therefore, it is inconvenient to provide the second air intake 115 on the inside of the end of the arm 13 closest to the connecting member 1021, and the amount of air intake by the second fan 54 is limited. By providing protrusion 12 at one end of arm portion 13 close to connecting member 1021, the volume of one end of arm portion 13 close to connecting member 1021 can be increased, and accordingly, the internal space of arm portion 13 at this location becomes larger. Therefore, by providing a larger second blower 54 and second air intake port 115 at the end of arm portion 13 close to connecting member 1021, the amount of air intake by second blower 54 can be increased, and the air blowing cooling effect and heat dissipation effect of second blower 54 can be improved.

[0231] The width direction of the arm portion 13 is a direction perpendicular to the length direction of the arm portion 13. In this embodiment, the main body portion 11 has a circular ring shape, the length direction of the arm portion 13 is the circumferential direction of the main body portion 11, and the width direction of the arm portion 13 may point in the axial direction of the main body portion 11 or in the radial direction of the main body portion 11. Specifically, the protrusion 12 protrudes outward along the axial direction of the main body portion 11, and the protrusion 12 and the second exhaust port 113 are located on opposing sides of the arm portion 13.

[0232] See Figures 99 and 101. The temperature adjustment assembly 50 further includes a heat dissipation member 5, which is located in the first exhaust path 57 and connected to the side of the temperature adjustment member 4 away from the temperature conduction member 2. When the temperature adjustment member 4 cools the user, the heat dissipation member 5 can absorb the hot air from the temperature adjustment member 4, which increases the contact area with the air and accelerates heat exchange with the air, improving the heat dissipation effect of the temperature adjustment member 4. In addition, when the air in the second exhaust path 58 moves toward the heat dissipation port 118, it flows through the heat dissipation member 5 and removes the hot air from the heat dissipation member 5, improving the heat dissipation ability of the heat dissipation member 5.

[0233] In this embodiment, the heat dissipation member 5 includes a substrate and a plurality of heat dissipation sheets arranged at intervals on the substrate. A heat dissipation passage is formed between two adjacent heat dissipation sheets. The extension direction of the heat dissipation passage is the same as the extension direction of the first exhaust path 57, i.e., the air flow direction, which is advantageous for reducing wind resistance and accelerating the air flow.

[0234] A graphene layer (not shown) is provided on the outer surface of the heat dissipation member 5. The graphene layer can improve the heat conduction efficiency, and is advantageous in further improving the heat dissipation effect of the heat dissipation member 5.

[0235] The temperature adjustment member 4 has a cold end and a hot end, and can switch between the cold end and the hot end depending on the direction of the current. When cooling is required, the cold end is connected to the temperature conduction member 2, and the cold current generated at the cold end is transferred to the user's neck using the temperature conduction member 2, thereby providing a cooling effect to the user. When heating is required, the hot end is connected to the temperature conduction member 2, and the heat current generated at the hot end is transferred to the user's neck using the temperature conduction member 2, thereby providing a heating effect to the user. At the same time, heating elements, such as resistance wires, may be provided in the cavity body 178 corresponding to the first and second fans 53 and 54. When air flows through the heating elements due to the operation of the first and second fans 53 and 54, the air is heated by the heating elements. As a result, the first and second fans 53 and 54 blow out hot air, providing a heating effect to the user.

[0236] The temperature conduction member 2 extends from one end of the arm 13 close to the connecting member 1021 in a direction away from the connecting member 1021. The connecting member 1021 and its surrounding area are both close to the back of the user's neck and can come into contact with the user due to gravity. Therefore, by having the temperature conduction member 2 extend from one end of the arm 13 close to the connecting member 1021 in a direction away from the connecting member 1021, at least a portion of the temperature conduction member 2, i.e., the portion close to the connecting member 1021, comes into contact with the user and can transmit the cold current generated by the temperature adjustment member 4 to the user. Specifically, in this embodiment, the second fan 54 is located between the connecting member 1021 and the temperature adjustment member 4, and one end of the temperature conduction member 2 is closer to the connecting member 1021 than the second fan 54. That is, at least a portion of the projection of the second fan 54 in the radial direction of the main body 11 is located on the temperature conduction member 2.

[0237] See Figure 101. Each arm portion 13 is equipped with a control assembly, which includes a circuit board 180, a battery 510, and a switch push button 40. The battery 510, the first fan 53, the second fan 54, and the temperature adjustment member 4 are all electrically connected to the circuit board 180. The battery 510 is used to supply electrical energy to the first fan 53, the second fan 54, and the temperature adjustment member 4, and the switch push button 40 is used by the user to control the start and stop of the first fan 53, the second fan 54, and the temperature adjustment member 4.

[0238] Although there is no limitation on the type of battery 510, in this embodiment, the battery 510 is a rechargeable battery. A charging port 540 for charging the battery 510 is provided on the arm portion 13.

[0239] As shown in Figures 103 to 106, the portable temperature adjusting device provided in the 21st embodiment of the present application is different from the portable temperature adjusting device of the first embodiment in that in this embodiment, the portable temperature adjusting device includes a main body 11, a temperature adjusting assembly 50, and a heat insulating member 70. The temperature adjusting assembly 50 includes a temperature adjusting member 4, a heat dissipating member 5, and a temperature conducting member 2. The temperature adjusting member 4 is specifically a semiconductor cooling sheet. The heat dissipating member 5 is disposed inside the main body 11, and the temperature conducting member 2 is fixedly connected to the main body 11, with at least a portion of the temperature conducting member 2 exposed to the outside of the main body 11. One side of the temperature adjusting member 4 is thermally conductively connected to the heat dissipating member 5, and the other side of the temperature adjusting member 4 is thermally conductively connected to the temperature conducting member 2. The heat insulating member 70 is located between the temperature conducting member 2 and the heat dissipating member 5, and is positioned to avoid the thermally conductive connection between the temperature adjusting member 4 and the temperature conducting member 2. During cooling, the temperature adjusting member 4 transfers cool air to the temperature conducting member 2 and hot air to the heat dissipating member 5. When the temperature conducting member 2 is in close contact with the skin of the human body, the temperature conducting member 2 cools the human body, and the heat dissipating member 5 dissipates the hot air to the outside of the main body 11. The heat insulating member 70 is positioned between the temperature conducting member 2 and the heat dissipating member 5 and is arranged to avoid the thermally conductive connection between the temperature adjusting member 4 and the temperature conducting member 2. This arrangement not only does not affect the thermal connection between the temperature adjusting member 4 and the temperature conducting member 2, but also prevents the hot air dissipated by the heat dissipating member 5 from being radiated to the temperature conducting member 2, which would increase the temperature of the temperature conducting member 2. This ensures that the cool air from the temperature conducting member 2 is not affected by the hot air dissipated by the heat dissipating member 5, allowing the temperature conducting member 2 to efficiently transfer cool air to the human body, improving the ability of the portable temperature adjusting device to cool the human body.

[0240] It should be noted that the term "thermal conduction connection" in this application means that two objects can be in direct contact with each other to form a hot or cold air transfer, or indirect contact with each other to form a hot or cold air transfer, for example, indirect contact via an intermediate heat conduction medium such as thermally conductive silicone grease / silica gel to form a hot or cold air transfer.

[0241] As can be seen, when the temperature adjusting member 4 heats up, it transfers hot air to the temperature conducting member 2 and cold air to the heat dissipating member 5. Therefore, when the temperature conducting member 2 is in close contact with the skin of the human body, the temperature conducting member 2 can provide heating to the human body, and the heat dissipating member 5 dissipates the cold air to the outside of the main body 11. At this time, the heat insulating member 70 can still block the energy transfer between the temperature conducting member 2 and the heat dissipating member 5.

[0242] In this embodiment, the heat insulating member 70 is provided with an escape opening 75, and the temperature adjustment member 4 is drilled through the escape opening 75 and thermally conductively connected to the temperature conduction member 2. The area of ​​the side of the temperature conduction member 2 facing the temperature adjustment member 4 is larger than the area of ​​the side of the temperature adjustment member 4 facing the temperature conduction member 2. Only a portion of the surface of the temperature conduction member 2 closest to the heat dissipation member 5 is thermally conductively connected to the temperature adjustment member 4. Therefore, the heat insulating member 70 avoids the temperature adjustment member 4 by using the escape opening 75 to prevent the other portions of the surface of the temperature conduction member 2 closest to the heat dissipation member 5 from being radiated by the hot air dissipated by the heat dissipation member 5. The heat insulating member 70 shields and covers the portion of the surface of the temperature conduction member 2 closest to the heat dissipation member 5 that is not connected to the temperature adjustment member 4, thereby blocking the influence of the heat dissipation member 5 transferring the hot air to the temperature conduction member 2 and ensuring that the temperature conduction member 2 transfers as much of the cold air transferred from the temperature adjustment member 4 to the human body as possible, thereby providing cooling and heat dissipation to the human body. In another embodiment, a retraction opening 75 is provided in the heat insulating member 70, and a boss 20 is provided to protrude from the temperature conducting member 2 on the side closer to the heat dissipation member 5. The boss 20 is drilled through the retraction opening 75 and is thermally conductively connected to the temperature adjusting member 4. The heat insulating member 70 is disposed close to the surface of the heat dissipation member 5 in correspondence with the temperature conducting member 2, and is positioned to avoid the boss 20.

[0243] As shown in Figures 105 and 106, in this embodiment, the heat insulating member 70 includes a heat insulating layer 76 and a reflective layer 77. The reflective layer 77 is disposed on the side of the heat insulating layer 76 closer to the heat dissipation member 5, and the heat insulating layer 76 can effectively block the heat dissipated by the heat dissipation member 5 from being transmitted to the temperature conducting member 2. Because the reflective layer 77 is disposed on the side of the heat insulating layer 76 closer to the heat dissipation member 5, when the heat dissipated by the heat dissipation member 5 is radiated toward the temperature conducting member 2, the reflective layer 77 can reflect the heat dissipated by the heat dissipation member 5, thereby further improving the heat insulating ability of the heat insulating member 70.

[0244] Furthermore, the reflective layer 77 is disposed on the side of the insulating layer 76 closer to the temperature conducting member 2, and the insulating layer 76 can prevent the hot air dissipated by the heat dissipation member 5 from being transmitted to the temperature conducting member 2. When the cold air generated by the temperature adjustment member 4 is transmitted to the temperature conducting member 2, part of the cold air from the temperature conducting member 2 is dissipated toward the reflective layer 77, and the reflective layer 77 can reflect part of the cold air from the temperature conducting member 2, so that the cold air dissipated from the temperature conducting member 2 is concentrated and transmitted to the human skin, and the temperature conducting member 2 can sufficiently transmit the cold air to the human body to cool the human body.

[0245] In addition, a reflective layer 77 is provided on both the side of the heat insulating layer 76 that is closer to the temperature conducting member 2 and the side of the heat insulating layer 76 that is closer to the heat dissipation member 5. This further improves the heat insulating effect of the heat insulating member 70, and ensures that the temperature conducting member 2 transfers cool air to the human skin as much as possible to cool the human body.

[0246] In this embodiment, the heat insulating layer 76 is an aerogel layer. The aerogel layer is located between the temperature conducting member 2 and the heat dissipation member 5, and is positioned to avoid the thermally conductive connection between the temperature adjusting member 4 and the temperature conducting member 2. Specifically, the aerogel layer is a nanosilica aerogel layer. The pore size of nanosilica aerogel is 20-50 nm. The nanoscale pore size is smaller than the mean free path of air molecules, and the porosity is high (95% or more), with a low density (0.03 g / ml or less). This allows for vacuum-like insulation, ensuring that the cool air from the temperature conducting member 2 is transferred to the human body as efficiently as possible.

[0247] In this embodiment, the reflective layer 77 is an aluminum foil reflective layer. The aluminum foil reflective layer is positioned between the temperature-conducting member 2 and the heat-dissipating member 5, avoiding the thermally conductive connection between the temperature-regulating member 4 and the temperature-conducting member 2. Specifically, the aluminum foil reflective layer is formed by laminating aluminum foil veneer, polyethylene film, fiber fabric, and a metal coating with a hot-melt adhesive. The aluminum foil reflective layer reflects hot or cold air radiated toward the aluminum foil reflective layer. That is, when the heat-dissipating member 5 radiates hot air toward the aluminum foil reflective layer, the aluminum foil reflective layer reflects the hot air, preventing the heat from the heat-dissipating member 5 from radiating toward the temperature-conducting member 2. Furthermore, when the temperature-conducting member 2 radiates cold air toward the aluminum foil reflective layer, the aluminum foil reflective layer reflects the cold air, allowing the cold air from the temperature-conducting member 2 to be radiated in a concentrated manner toward the human body, thereby transferring as much cold air as possible to the human body.

[0248] In this embodiment, the temperature conducting member 2 is a metal temperature conducting member mixed with graphene powder, which can further improve the thermal conductivity of the temperature conducting member 2.

[0249] As shown in FIGS. 107 and 108 , the 22nd embodiment differs from the 21st embodiment in that the portable temperature adjusting device includes a temperature uniformizing member 78, which is positioned between the heat insulating member 70 and the temperature conducting member 2. The heat insulating member 70 may include at least one of a heat insulating layer 76 and a reflective layer 77. The temperature uniformizing member 78 is specifically a graphene or graphite layer and covers the side of the temperature conducting member 2 closest to the temperature adjusting member 4. When the temperature adjusting member 4 transfers cold air to the temperature conducting member 2, the temperature uniformizing member 78 can quickly disperse the cold air near the temperature adjusting member 4 on the temperature uniformizing member 78 and transfer it to the temperature conducting member 2, thereby achieving a relatively uniform distribution of cold air at each location on the temperature conducting member 2. When the temperature conducting member 2 comes into contact with the human body, the temperature conducting member 2 can transfer cold air to the human body evenly. The temperature uniformizing member 78 is connected to the temperature conducting member 2 by adhesive. The adhesive is a thermally conductive adhesive.

[0250] As shown in Figures 103 to 108, in the 21st and 22nd embodiments, the temperature conduction member 2 is disposed on the outer surface of the main body 11, and the heat insulating member 70 is located between the outer surface of the main body 11 and the temperature conduction member 2. The temperature conduction member 2 is fixedly connected to the main body 11. The temperature conduction member 2 sandwiches and fixes the heat insulating member 70 to the main body 11. In other embodiments, the heat insulating member 70 may be fixed to the main body 11 or the temperature conduction member 2 by a method such as adhesion or locking. When the heat insulating member 70 includes a heat insulating layer 76 and a reflective layer 77, the heat insulating layer 76 is connected to the reflective layer 77 with an adhesive, or the heat insulating layer 76 and the reflective layer 77 are arranged in a stack and sandwiched and fixed to the main body 11 by the temperature conducting member 2. Because the heat insulating member 70 is located between the main body 11 and the temperature conducting member 2, it can prevent the hot air dissipated by the heat dissipation member 5 from passing through the main body 11 and radiating to the temperature conducting member 2, and it can also prevent the temperature conducting member 2 from transferring a portion of the cold air to the main body 11, ensuring that the cold air in the temperature conducting member 2 is not consumed by the main body 11 and remains sufficiently cold. This allows the temperature conducting member 2 to transfer as much cold air as possible to the human body, solving the problem of a significant reduction in the amount of cold air transferred by the temperature conducting member 2 to the human body, and improving the cooling and heat dissipation capabilities of the portable temperature adjusting device for the human body.

[0251] In another embodiment, the temperature conduction member 2 may be disposed on the inner surface of the main body 11. That is, the temperature conduction member 2 is located inside the main body 11, and at least a portion of the temperature conduction member 2 protrudes toward the outside of the main body 11 and is exposed to the outside of the main body 11. The heat insulating member 70 may be fixed to the side of the temperature conduction member 2 closer to the heat dissipation member 5 with an adhesive, without being sandwiched and fixed to the main body 11 by the temperature conduction member 2.

[0252] Furthermore, the portable temperature regulating device may be a neck-worn air conditioner, a handheld air conditioner, a head-worn air conditioner, or a neck-worn air conditioner. Hereinafter, the portable temperature regulating device will be described as a neck-worn air conditioner. Specifically, the main body 11 is provided with a surrounding mounting space 10, and the temperature conducting member 2 is located on the side of the main body 11 closest to the mounting space 10. When a user wears the portable temperature regulating device around their neck, their neck is located within the mounting space 10, and their neck skin comes into contact with the temperature conducting member 2. That is, when the temperature regulating member 4 operates, the cool air generated by the temperature regulating member 4 is transferred to the temperature conducting member 2, which then transfers the cool air to their neck skin.

[0253] Furthermore, a recess 183 is formed on the side of the main body 11 closer to the mounting cavity 21, and the heat insulating member 70 and the temperature conducting member 2 are positioned within the recess 183, thereby reducing the overall thickness of the portable temperature adjusting device. Specifically, the temperature conducting member 2 is fixedly connected to the main body 11, and the heat insulating member 70 is sandwiched between the bottom of the recess 183 and the temperature conducting member 2.

[0254] As shown in Figures 103 to 108, specifically, a mounting cavity 184 and a storage cavity that communicate with each other are provided inside the main body 11. The portable temperature adjusting device further includes a partition member 138 and a blower 3, where the blower 3 is disposed in the mounting cavity 184 and the partition member 138 is disposed in the storage cavity, dividing the storage cavity into a heat dissipation cavity 166 and an air duct 17. Both the heat dissipation cavity 166 and the air duct 17 communicate with the mounting cavity 184. The heat dissipation member 5 is disposed in the heat dissipation cavity 166. An exhaust port 16 is provided on the side of the main body 11 adjacent to the installation space 10, and the exhaust port 16 communicates with one end of the air duct 17 that is remote from the mounting cavity 184. A heat dissipation port 118 is provided on the opposite side of the mounting space 10 of the main body 11, and the heat dissipation port 118 is connected to one end of the heat dissipation cavity 166 that is remote from the mounting cavity 184. The main body 11 is further provided with an air intake port 15 that is connected to the mounting cavity 184. That is, when the blower 3 operates in the mounting cavity 184, gas drawn in through the air intake port 15 is accelerated within the mounting cavity 184, forming an airflow that is blown toward the heat dissipation cavity 166 and the air duct 17. The airflow that passes through the heat dissipation cavity 166 carries the hot air dissipated by the heat dissipation member 5 and is blown out through the heat dissipation port 118, and the airflow that passes through the air duct 17 is blown out through the air exhaust port 16. When a user wears the portable temperature control device around their neck, the air blown out through the air exhaust port 16 can be blown toward their face or other locations to cool the human body. The temperature conducting member 2 can transmit the cool air to the skin of the neck, further enhancing the cooling ability for the human body.

[0255] 109 to 114, a 23rd embodiment of the present application provides a portable temperature control device with excellent exhaust and temperature control effects. Compared to the first embodiment, this embodiment includes an arm portion 13, a conductive member 900, a fan wheel 3, and a temperature control member 4. An air duct 17 is provided within the arm portion 13. The conductive member 900 is disposed within the air duct 17 and divides the air duct 17 into at least a first air duct 17a and a second air duct 17b. The first air duct 17a and the second air duct 17b communicate with each other. An air intake 15 is provided in the arm portion 13 at a position corresponding to the first air duct 17a, and an air exhaust 16 is provided in the arm portion 13 at a position corresponding to the second air duct 17b. The fan wheel 3 is disposed within the air duct 17. The temperature control member 4 is disposed within the arm portion 13 and is thermally conductively connected to the conductive member 900.

[0256] In this application, the term "thermal conduction connection" refers to the fact that two objects can be in direct contact with each other to form a thermal conduction, or indirect contact with each other to form a thermal conduction, for example, indirect contact via an intermediate thermal conduction medium such as thermally conductive silicone grease / silica gel or graphite to form a thermal conduction.

[0257] The portable temperature regulating device provided by the embodiments of the present application cools or heats the conductive member 900 via the temperature regulating member 4, and also divides the air duct 17 into at least the first air duct 17a and the second air duct 17b by the conductive member 900. As the airflow entering through the air intake 15 flows through the first air duct 17a and the second air duct 17b, it comes into contact with the conductive member 900 and is sufficiently cooled or heated, and finally the airflow blown out from the air outlet 16 becomes cooler or warmer. This allows the portable temperature regulating device to have a good temperature regulating effect.

[0258] The temperature adjustment member 4 is preferably a semiconductor cooling sheet. When the temperature adjustment member 4 is energized, its opposing sides constitute a cold end and a hot end, respectively, and the cold end and the hot end can be switched between them depending on the direction of the current. When cooling is required, the cold end of the temperature adjustment member 4 can be thermally conductively connected to a temperature-regulated member (e.g., conductive member 900), thereby cooling both the airflows flowing through the first air duct 17a and the second air duct 17b, and thus making the airflow blown out from the exhaust port 16 cooler. Conversely, when heat is required, the hot end of the temperature adjustment member 4 can be thermally conductively connected to a temperature-regulated member (e.g., conductive member 900), thereby heating both the airflows flowing through the first air duct 17a and the second air duct 17b, and thus making the airflow blown out from the exhaust port 16 warmer.

[0259] Optionally, the arm portion 13 includes an inner case 136 and an outer case 135 attached to each other by snap-fitting, and the air duct 17 is formed between the inner case 136 and the outer case 135. Specifically, a first air duct 17a is formed between the outer case 135 and the conductive member 900, and the first air duct 17a extends along the length direction of the arm portion 13, and the air intake port 15 is arranged on a side wall of the outer case 135. A second air duct 17b is formed between the inner case 136 and the conductive member 900, and the second air duct 17b extends along the length direction of the arm portion 13 and is located inside the first air duct 17a, and the air exhaust port 16 is arranged on the top wall of the inner case 136, and optionally the air exhaust port 16 includes a plurality of strip-shaped exhaust holes arranged side by side.

[0260] Optionally, the air duct 17 further includes a heat dissipation air duct 175 that communicates with the first air duct 17a.

Specifically, the heat dissipation port 118 is disposed on the side wall of the outer case 135, and includes a plurality of strip-shaped heat dissipation holes arranged side by side.

[0261] Optionally, a first rotating shaft 1353 and an air throttling member 1354 provided to surround the periphery of the first rotating shaft 1353 and extend toward the first air duct 17a are formed inside the outer case 135. Specifically, the air throttling member 1354 is disposed within one end of the first air duct 17a, and both opposing ends of the air throttling member 1354 each have an opening 1355. One opening 1355 faces toward the other end of the first air duct 17a, and the other opening 1355 faces toward the heat dissipation air duct 175.

[0262] Optionally, the air intake 15 includes a plurality of air intake holes arranged in an annular shape, the plurality of air intake holes being arranged around the first rotating shaft 1353 and positioned between the first rotating shaft 1353 and the air throttling member 1354.

Preferably, the first fan wheel 3a is a centrifugal fan wheel, and the first fan wheel 3a is disposed at one end of the first air duct 17a close to the heat dissipation air duct 175. The air intake side of the first fan wheel 3a faces the air intake 15, and the air exhaust side of the first fan wheel 3a faces the other end of the first air duct 17a remote from the heat dissipation air duct 175 and the heat dissipation air duct 175, respectively. The first fan wheel 3a guides a portion of the airflow to the other end of the first air duct 17a away from the heat dissipation air duct 175, and the first fan wheel 3a guides another portion of the airflow into the heat dissipation air duct 175, thereby dissipating the hot air generated in the temperature adjustment member 4 to the outside through the heat dissipation port 118.

[0264] Optionally, a battery cavity 185 is further formed inside the outer case 135. The battery cavity 185 is formed between the outer case 135 and the conductive member 900. The battery cavity 185 and the heat dissipation air duct 175 are separated by a partition plate 186. A battery 510 is provided in the battery cavity 185 and is used to supply power to the fan wheel 3.

[0265] Optionally, the conductive member 900 is made of a thermally conductive material such as a metal material. In this embodiment, the conductive member 900 is made of an aluminum material so that the cold or hot air generated in the temperature adjustment member 4 can be transferred into the first air duct 17a and the second air duct 17b, thereby improving the temperature adjustment efficiency.

[0266] Optionally, the conductive member 900 is provided with an air vent 910, and the first air duct 17a and the second air duct 17b communicate with each other through the air vent 910. Preferably, the air vent 910 includes a plurality of air holes arranged in an annular shape. The second fan wheel 3b is disposed corresponding to the position of the air vent 910. The intake side of the second fan wheel 3b is disposed facing the air vent 910, so that airflow can flow from the first air duct 17a into the second air duct 17b through the air vent 910 by driving the second fan wheel 3b.

[0267] In another embodiment, the conductive member 900 may not be provided with the ventilation opening 910. In this case, the air duct 17 further includes a ventilation air duct, which is located at one end of the conductive member 900. The first air duct 17a and the second air duct 17b are located on opposite sides of the conductive member 900, and the first air duct 17a and the second air duct 17b communicate with each other via the ventilation air duct. The fan wheel 3 is located in the ventilation air duct.

[0268] Optionally, the conductive member 900 is further provided with a through hole 920 , which is positioned facing the heat dissipation vent 118 .

[0269] Optionally, the first air duct 17a extends along the length of the arm portion 13, and the air inlet 15 and the air vent 910 are respectively located at opposite ends of the first air duct 17a, whereby the air inlet 15 and the air vent 910 are offset inward and outward along the arm portion 13, thereby increasing the length of the first air duct 17a and allowing the airflow to cool or heat more efficiently within the first air duct 17a. Of course, in other embodiments, the air inlet 15 and the air vent 910 may be located at the same end of the first air duct 17a, in which case the air inlet 15 is located facing the air vent 910, and the first fan wheel 3a is located between the air inlet 15 and the air vent 910.

[0270] Optionally, a circuit board 180 may be further provided within the first air duct 17a. The circuit board 180 is disposed facing the ventilation opening 910 and is electrically connected to the battery 510, the fan wheel 3, and the temperature adjustment member 4, respectively. Specifically, the circuit board 180 is provided with a switch 187, a display screen 188, and a charging terminal 189. A push button 40 cooperating with the switch 187 and a display window 49 for displaying the display screen 188 are provided on the side wall of the outer case 135. The push button 40 is used to control the start / stop and stage of the fan wheel 3 and the temperature adjustment member 4, respectively. The display screen 188 is used to display information on the amount of electricity in the battery 510, information on the stage of the fan wheel 3, and information on temperature adjustment of the temperature adjustment member 4. A charging port 540 is provided on the bottom wall of the outer case 135 for receiving a charging terminal 189 , which is used to connect to an external power source to charge the battery 510 .

[0271] Optionally, the temperature-adjusted member further includes a temperature-conducting member 2. In this embodiment, a first mounting hole 1365 and a temperature-conducting member 2 mounted in the first mounting hole 1365 are provided on the side wall of the inner case 136. The temperature-conducting member 2 is exposed on the side wall of the inner case 136 and is thermally conductively connected to the conductive member 900. The temperature-conducting member 2 is brought into contact with the user's area to be temperature-adjusted and is used to adjust the temperature by icing or applying a heat pack.

[0272] Optionally, the temperature conducting member 2 and the conducting member 900 are attached to each other by snap-fitting, and a second air duct 17b is formed between the temperature conducting member 2 and the conducting member 900, so that when the airflow flows through the second air duct 17b, both the temperature conducting member 2 and the conducting member 900 can temperature-regulate the airflow, thereby improving the temperature-regulating effect on the airflow.

[0273] Optionally, the temperature conduction member 2 is made of a thermally conductive material such as a metal material. In this embodiment, the temperature conduction member 2 is made of an aluminum material so that the cold or hot air generated by the temperature adjustment member 4 can be better transferred to the user's temperature-adjusted area, thereby improving the temperature adjustment efficiency.

[0274] Optionally, the inside of the temperature conducting member 2 extends toward the second air duct 17b to form a second rotation axis 220. The fan wheel 3 includes a second fan wheel 3b, which is disposed within the second air duct 17b. Specifically, the second fan wheel 3b is rotatably mounted on the second rotation axis 220. Preferably, the second fan wheel 3b is a centrifugal fan wheel.

[0275] In another embodiment, the temperature conduction member 2 may not be provided on the side wall of the inner case 136. Correspondingly, the side wall of the inner case 136 may be provided with an air intake 15. The air intake 15 includes a plurality of air intake holes arranged in an annular shape, and the plurality of air intake holes are arranged so as to surround the periphery of the second rotation shaft 220. This increases the amount of air intake by the second fan wheel 3b, improving wind power and making the airflow blown out from the exhaust port 16 stronger.

[0276] Preferably, the fan wheel 3 includes a first fan wheel 3a and a second fan wheel 3b. The first fan wheel 3a blows the airflow entering through the intake port 15 from one end of the first air duct 17a to the other end of the first air duct 17a. The airflow is then drawn in through the ventilation opening 910 via the second fan wheel 3b, and then blown out through the exhaust port 16 via the second air duct 17b. This allows the airflow to smoothly enter the intake port 15 and finally blow out through the exhaust port 16 even if the lengths of the first air duct 17a and the second air duct 17b are increased. The airflow can be cooled or heated more sufficiently in the longer first air duct 17a and second air duct 17b, ensuring that the airflow blown out through the exhaust port 16 is cooler or warmer. Naturally, in another embodiment, the fan wheel 3 may include only either the first fan wheel 3a or the second fan wheel 3b.

[0277] Optionally, the temperature-adjusted member further includes an air guide member 58, which is connected to one side of the temperature-conducting member 2. In this embodiment, the air guide member 58 is disposed within the arm portion 13 and connected to the inside of the temperature-conducting member 2, and the air guide member 58 is thermally conductively connected to the temperature adjustment member 4. Preferably, one side of the air guide member 58 is integrally connected to the temperature-conducting member 2, and the other side of the air guide member 58 contacts one side of the conduction member 900. Of course, the air guide member 58 and the temperature-conducting member 2 may be separate structures that are attached and fixedly connected to each other.

[0278] Optionally, the conductive member 900, the temperature conductive member 2, and the air guide member 58 together surround and form the second air duct 17b. When the air flows through the second air duct 17b, the conductive member 900, the temperature conductive member 2, and the air guide member 58 can all adjust the temperature of the air, thereby maximizing the temperature adjustment effect on the air.

[0279] Optionally, the air guide member 58 includes an arc-shaped air guide plate 581 and an air guide sheet 582 connected to each other. The arc-shaped air guide plate 581 is disposed to surround the periphery of the second fan wheel 3b, and the air guide sheet 582 extends from one end of the arc-shaped air guide plate 581 toward the exhaust port 16. The arc-shaped air guide plate 581 is used to compress the wind force generated by the second fan wheel 3b, allowing the airflow to flow more quickly to the air guide sheet 582 and preventing backflow of the airflow. The air guide sheet 582 is used to guide the airflow to the exhaust port 16 for discharge. Preferably, the arc-shaped air guide plate 581 and the air guide sheet 582 are connected integrally.

[0280] Optionally, a mounting cavity 230 is further formed inside the temperature conducting member 2, and the mounting cavity 230 and the second air duct 17b are separated by an air guide sheet 582. The temperature adjusting member 4 is accommodated in the mounting cavity 230. The temperature adjusting member 4 and the temperature conducting member 2 are in indirect contact with each other via thermally conductive silicone grease / silica gel to achieve heat transfer, so that the cold or hot air generated by the temperature adjusting member 4 can not only be conducted to the temperature conducting member 2, but can also be indirectly conducted to the conduction member 900 and the air guide member 58 via the temperature conducting member 2.

[0281] In another embodiment, optionally, the temperature adjustment member 4 and the conduction member 900 may be in indirect contact with each other via thermally conductive silicone grease / silica gel to form a hot air transfer, or the temperature adjustment member 4 and the air guide member 58 may be in indirect contact with each other via thermally conductive silicone grease / silica gel to form a hot air transfer, thereby similarly realizing that the cold air or hot air generated by the temperature adjustment member 4 is conducted to the temperature conduction member 2, the conduction member 900 and the air guide member 58, that is, the temperature conduction member 2, the conduction member 900 and the air guide member 58 are each thermally conductively connected to the temperature adjustment member 4.

[0282] Optionally, a heat dissipation member 5 is further provided within the arm portion 13. The temperature adjustment member 4 is sandwiched between the heat dissipation member 5 and the temperature conduction member 2. A portion of the heat dissipation member 5 is accommodated within the mounting cavity 230 and is thermally conductively connected to the temperature adjustment member 4, while another portion of the heat dissipation member 5 passes through the through-hole 920 and enters the heat dissipation air duct 175, allowing the hot air generated by the temperature adjustment member 4 to quickly diffuse into the heat dissipation air duct 175. Preferably, the heat dissipation member 5 and the temperature adjustment member 4 are in indirect contact with each other via thermally conductive silicone grease / silica gel, thereby achieving heat transfer.

[0283] Optionally, the portable temperature control device may be a neck-mounted air conditioner, a waist-mounted air conditioner, or a handheld air conditioner. In this embodiment, the portable temperature control device is a neck-mounted air conditioner. The portable temperature control device includes two arms 13 and an elastic return element 8 connecting the two arms 13. The two arms 13 can be moved away from each other by an external force, deforming the elastic return element 8, making it easy for the user to wear the portable temperature control device around the neck. After wearing the portable temperature control device around the neck, when the external force applied to the two arms 13 is removed, the elastic return element 8 automatically elastically returns, allowing the temperature conducting members 2 on the inner walls of the two arms 13 to remain in close contact with the neck, allowing the user to adjust the temperature of the neck using ice or a hot pack. When the portable temperature control device is worn around the neck of a user, the air outlets 16 of the two arms 13 may blow air toward the head of the user, or toward the back of the user.

[0284] Please also refer to Figures 115 to 120. This is a portable temperature control device provided by the 24th embodiment of the present application.

Opposite ends of the connecting member 145 are integrally connected to the top and bottom walls of the conductive member 900, respectively, and the side of the connecting member 145 away from the temperature-conducting member 2 is thermally conductively connected to one side of the temperature control member 4. Preferably, the connecting member 145 and the temperature control member 4 are in indirect contact via thermally conductive silicone grease / silica gel, allowing for heat transfer. Correspondingly, a second mounting hole 1356 is provided in the side wall of the outer case 135, through which the temperature control member 4 is drilled. The heat dissipation member 5 is attached and fixed to the side wall of the outer case 135 and thermally conductively connected to the other side of the temperature adjustment member 4. In other words, one side of the heat dissipation member 5 is thermally conductively connected to the temperature adjustment member 4, and the other side of the heat dissipation member 5 is exposed to the outside of the side wall of the outer case 135. Preferably, the heat dissipation member 5 and the temperature adjustment member 4 are in indirect contact via thermally conductive silicone grease / silica gel, thereby achieving heat transfer. The arm unit 13 further includes a cover plate 192, which covers the heat dissipation member 5 and is attached and fixed to the side wall of the outer case 135. A heat dissipation passage 193 extending along the length of the outer case 135 is formed on the side of the cover plate 192 facing the outer case 135, and the heat dissipation member 5 is accommodated within the heat dissipation passage 193. The heat dissipation member 5 quickly diffuses the heat generated by the temperature adjustment member 4 into the heat dissipation passage 193 and dissipates it to the outside from both ends of the heat dissipation passage 193. In another embodiment, an opening is provided in the side wall of the arm portion 13. The heat dissipation member 5 is disposed in the opening and exposed to the outside of the arm portion 13, or the heat dissipation member 5 is disposed inside the arm portion 13 and exposed to the outside of the arm portion 13 through the opening. Accordingly, a cover plate 192 may be provided on the arm portion 13, and similarly, hot air generated by the temperature adjustment member 4 can be quickly diffused to the outside of the arm portion 13 via the heat dissipation member 5.

[0285] Please also refer to Figures 121 to 125. This is a portable temperature adjusting device provided by the 25th embodiment of the present application.

The arm portion 13 is provided with a heat dissipation port 118 at a position corresponding to the heat dissipation air duct 175. A heat dissipation member 5 is disposed within the heat dissipation air duct 175, and the heat dissipation member 5 quickly diffuses the hot air generated by the temperature adjustment member 4 into the heat dissipation air duct 175.

[0286] Optionally, a partition member 138 may be further provided within the arm portion 13, and the partition member 138 includes a first partition portion 1382 and a second partition portion 1384 connected to one side of the first partition portion 1382. Specifically, the second partition portion 1384 is integrally connected to the outside of the first partition portion 1382.

[0287] Optionally, the first partition 1382 is positioned between the second air duct 17b and the heat dissipation air duct 175 to separate the second air duct 17b from the heat dissipation air duct 175 and prevent the airflows entering the second air duct 17b and the heat dissipation air duct 175 from affecting each other. The second partition 1384 is positioned between the conductive member 900 and the heat dissipation air duct 175 to separate the conductive member 900 from the heat dissipation air duct 175 and prevent the airflows entering the heat dissipation air duct 175 from affecting the temperature conduction effect of the conductive member 900. Specifically, the second air duct 17b and the heat dissipation air duct 175 are positioned on the upper and lower sides of the first partition 1382, respectively, and the heat dissipation air duct 175 and the conductive member 900 are positioned on the inner and outer sides of the second partition 1384.

[0289] Optionally, the conduction member 900 is formed with a plurality of first temperature-conducting portions 930 extending toward the inside of the first air duct 17a. A first air guide passage 940 is formed between two adjacent first temperature-conducting portions 930, thereby increasing the contact area between the airflow and the conduction member 900 and enabling the airflow to be cooled or heated more effectively.

This arrangement not only allows airflow to smoothly enter each first air guide passage 940 from the air intake port 15 via the first communication passage 950, but also allows airflow in a first air guide passage 940 without an air vent 910 to smoothly flow through the second communication passage 960 into a first air guide passage 940 with an air vent 910, and then enter the second air duct 17b from the air vent 910.
