[0044] In this embodiment, the portable temperature control device 1 can be, for example, a neck hanging fan, a handheld fan, or a wearable fan, etc. In order to more clearly describe this embodiment, the following embodiments are all described with the portable temperature control device 1 being a neck hanging fan.

[0045] [First embodiment]

[0046] As shown in FIG. 1 to FIG. 4 , this embodiment provides a portable temperature control device 1 , which is, for example, a neck hanging fan. The portable temperature control device 1 may, for example, include: a housing 10 and a temperature conducting component 20 .

[0047] Specifically, the thermal conductive component 20 is disposed in the housing 10 , and includes a temperature regulating component 21 , a thermal conductive component 22 , and a power source 23 .

[0048] In this embodiment, the temperature regulating component 21 is arranged in the shell 10 and is thermally connected to the thermal conductive component 22. Fluid is arranged in the thermal conductive component 22. The power source 23 is arranged on the thermal conductive component 22, and the power source 23 can be used to drive the fluid in the thermal conductive component to circulate in the thermal conductive component 22. The temperature regulating component 21 is, for example, a temperature regulating plate. The temperature regulating plate is used for cooling or heating to adjust the temperature of the conductive plate. In this embodiment, the temperature regulating plate can be, for example, a semiconductor refrigeration plate, and the cold end surface of the semiconductor refrigeration plate is in contact with the thermal conductive component 22. The thermal conduction connection in this embodiment refers to the direct contact between two objects to form heat transfer, or indirect contact to form heat transfer, for example, indirect contact can be formed through an intermediate heat conducting medium such as thermal grease / silicone or graphite to form heat transfer.

[0049] The thermal conductive member 22 is, for example, a temperature-uniform film, specifically a PET film, and a fluid is provided inside the thermal conductive member 22. The fluid may be, for example, a liquid cooling medium, and the liquid cooling medium may be, for example, a fluorinated liquid or an ethanol solution. The thermal conductive member 22 drives the liquid to circulate in the thermal conductive member through the power source 23, so that the heat or cold generated by the thermostat is distributed throughout the thermal conductive member 22 through the circulation of the liquid in the thermal conductive member, thereby achieving uniform heat or cold at each position on the thermal conductive member 22, so that the heat or cold generated by the thermostat is uniformly conducted to human body parts such as the neck through the thermal conductive member 22, and thus when the user uses the neck hanging fan of this embodiment, the user's neck part will not feel the discomfort of uneven temperature, thereby improving the user's sense of use and comfort.

[0050] In this embodiment, the power source 23 can be, for example, a micro-liquid pump, such as a piezoelectric liquid pump. The piezoelectric pump utilizes the inverse piezoelectric effect of piezoelectric materials, that is, under the action of an electric field, the piezoelectric ceramic material will undergo tensile or compressive deformation, driving the metal sheet under the ceramic sheet to bulge upward or dent downward, thereby generating suction or pressure on the liquid, and forming a one-way flow of the fluid under the action of the one-way valve. Through the relevant principles of the piezoelectric liquid pump, the fluid in the thermal conductive member 22 can form a one-way flow, thereby forming a fluid flow loop. As shown in Figures 2 and 3, the power source 23 can be connected to the circuit board 30 disposed inside the housing 10 via a wire.

[0051] The embodiment of the present invention sets a heat conduction connection between the temperature conducting component 22 and the temperature regulating component 21, and drives the fluid in the temperature conducting component 22 to flow through the power source 23 to drive the heat or cold generated by the temperature regulating component 21 to flow evenly in the temperature conducting component 22, so that the heat or cold generated by the portable temperature regulating device 1 can be evenly dissipated to the human body, thereby allowing the user to feel uniform heat or cold, thereby improving the user's sense of use and experience.

[0052] In this embodiment, as shown in FIG1 , the shell 10 can define a wearing space 50, and the heat conducting component 20 is arranged on a side close to the wearing space 50. In other embodiments, the shell 10 may, for example, include a connector 101 and a first arm 102 and a second arm 103 arranged at both ends of the connector 101. The heat conducting component 20 can be arranged on a side of the first arm 102 and the second arm 103 close to the wearing space 50, or on a side of the first arm 102 and the second arm 103 and the connector 101 close to the wearing space 50. The heat conducting component 20 can also be arranged only on the first arm 102 or the second arm 103 or the connector 101, and the specific details are not limited here. The provision of the connector 101 enables the heat conducting component 20 on the shell 10 to maintain a state of fitting the human neck.

[0053] In a preferred embodiment of the present embodiment, as shown in Figures 1 to 4, the thermal conductor 22, for example, includes a thermal conductor body 221 and a flow channel loop 222. The thermal conductor body 221 may be composed of an upper sealing layer, a middle flow channel layer, and a lower sealing layer, and the flow channel loop 222 may be formed by hollowing out the middle flow channel layer. The power source 23 is arranged at a position outside the thermal conductor body 221 corresponding to the temperature regulating component 21, that is, the power source 23 may be arranged at a position where the thermal conductor 22 does not contact the temperature regulating component 21, and the position of the temperature regulating component 21 is avoided by such a staggered arrangement. In other embodiments, the power source 23 may also be a component structure on the thermal conductor 22, or may be an independent component, and may be arranged according to actual needs, which is not specifically limited here.

[0054] Wherein, the flow channel loop 222 is arranged on the thermal conductive part body 221. The power source 23 is used to drive the fluid to circulate in the flow channel loop 222. Thus, the heat or cold generated by the thermostat 21 is evenly distributed throughout the thermal conductive part 22 by the circulation of the fluid in the flow channel loop 223, thereby achieving the effect of uniform temperature at each position on the thermal conductive part 22, thereby improving the user experience. In this embodiment, the flow channel loop 222 may, for example, include a first flow channel 2221 and a second flow channel 2222 that are connected. Wherein, the first flow channel 2221 may be arranged at a position of the thermal conductive part body 221 corresponding to the thermostat 21, and the first flow channel 2221 is thermally conductively connected to the thermostat 21. The second flow channel 2222 is at a position outside the thermal conductive part body 221 corresponding to the thermostat 21. In other embodiments, the first flow channel 2221 and the second flow channel 2222 may be provided only at the location of the temperature conducting element 221 corresponding to the temperature regulating element 21 or only at a location outside the temperature regulating element 21. The locations of the first flow channel 2221 and the second flow channel 2222 may be determined based on actual needs and are not specifically limited herein. The power source 23 may be provided at a location outside the temperature regulating element 21 on the temperature conducting element 221 and connected to the second flow channel 2222.

[0055] As shown in Figures 2 and 3, the thermal conductive component further includes, for example, a conductive member 24. In this embodiment, the conductive member 24 is disposed on the housing 10 and is located on a side of the thermal conductive member 22 away from the thermostat 21; the conductive member 24 is thermally connected to the thermal conductive member 22. The conductive member 24 can be, for example, a metal conductive sheet. Through the thermal conductive connection between the conductive member 24 and the thermal conductive member 22, the heat or cold generated by the thermostat 21 is quickly and evenly distributed throughout the conductive member 24 through the circulation of the fluid within the thermal conductive member 22, thereby achieving a uniform temperature at every location on the conductive member 24, thereby improving the user experience and usage effect. In other embodiments, the conductive member 24 can be, for example, disposed between the thermostat 21 and the thermal conductive member 22, that is, the conductive member 24 is disposed on a side of the thermal conductive member 22 closer to the thermostat 21, and the thermal conductive member 22 can serve as a component that fits the human neck. The heat conduction efficiency is further improved by disposing a conductive member 24 between the temperature regulating member 21 and the heat conducting member 22. The specific position of the conductive member 24 can be set on the side of the heat conducting member 22 away from the temperature regulating member 21 or on the side of the heat conducting member 22 close to the temperature regulating member 21 according to actual needs, and the specific position is not limited here.

[0056] In this embodiment, as shown in Figures 2-3, the thermal conductive assembly 20 further includes, for example, a first thermal conductive layer 25 and a second thermal conductive layer 26. The first thermal conductive layer 25 is disposed between the thermal conductive member 22 and the thermostat 21, and is thermally conductively connected to the thermal conductive member 22 and the thermostat 21, respectively. The second thermal conductive layer 26 is disposed between the thermal conductive member 22 and the conductive member 24, and is thermally conductively connected to the thermal conductive member 22 and the conductive member 24. The first thermal conductive layer 25 and the second thermal conductive layer 26 can be, for example, thermal conductive layers composed of an intermediate thermal conductive medium such as thermal grease / silicone or graphite. By disposing the first thermal conductive layer 25 and the second thermal conductive layer 26 between the conductive member 24, the thermal conductive member 22, and the thermostat 21, the gaps between the conductive member 24, the thermal conductive member 22, and the thermostat 21 can be filled, thereby improving the heat conduction efficiency between the conductive member 24, the thermal conductive member 22, and the thermostat 21. In other embodiments, when the conductive member 24 is arranged between the temperature conductive member 22 and the temperature regulating member 21, the first heat conductive layer 25 can be arranged between the conductive member 24 and the temperature regulating member 21, and the second heat conductive layer 26 can be arranged between the conductive member 24 and the temperature conductive member 22. The positions of the first heat conductive layer and the second heat conductive layer can be adjusted according to the relative position between the conductive member 24 and the temperature conductive member 21, and the specific details are not limited here.

[0057] In a preferred embodiment of the present embodiment, as shown in FIG3 , the shell 10 may include a first shell portion 104 and a second shell portion 105, wherein the first shell portion 104 is a shell close to the human body part, and the second shell portion 105 is a shell away from the human body part. The first shell portion 104 and the second shell portion 105 are interconnected to form the shell 10. The thermal conductive member 22 and the conductive member may be arranged on the side of the first shell portion 104 facing the wearing space. A heat sink 40 may be provided in the shell 10, and the heat sink 40 is arranged near the second shell portion 105. The heat sink 40 is thermally conductively connected to the temperature regulating member 21. The temperature conductive component 20 may also include, for example, a fourth heat conductive layer 28, and the fourth heat conductive layer 28 is arranged between the temperature regulating member 21 and the heat sink 40, so as to improve the heat dissipation efficiency of the temperature regulating member 21.

[0058] [Second embodiment]

[0059] The structure of the neck-hanging fan 1 provided in this embodiment is basically the same as the structure of the neck-hanging fan provided in the aforementioned first embodiment, and the main differences are: a first protrusion 223 is provided on the heat conducting member 22; a second protrusion 241 is provided on the conducting member 24, and the heat conducting component 20 further includes, for example, a third heat conducting layer 27.

[0060] Specifically, as shown in Figures 5 and 6, a first protrusion 223 is provided on the side of the thermal conductive member 22 near the thermostat 21. The first protrusion 223 is thermally connected to the thermostat 21 through the first heat conductive layer 25. The size of the first protrusion 223 is adapted to the size of the thermostat 21. The first protrusion 223 can be, for example, a bump or a ridge, and the size of the first protrusion 223 can be adaptively adjusted according to the size of the thermostat 21. The provision of the first protrusion 223 can further improve the efficiency of the thermal conduction connection between the thermal conductive member 22 and the thermostat 21.

[0061] In a preferred embodiment of this embodiment, as shown in Figures 4 and 5 , the conductive member 24 is disposed on a side of the thermal conductive member 22 away from the thermostat 21. A second protrusion 241 is disposed on the side of the conductive member 24 close to the thermostat 21. The second protrusion 241 corresponds to the first protrusion 223, i.e., the size of the second protrusion 241 is the same as that of the first protrusion 223. The thermal conductive assembly 20 further includes a third heat-conducting layer 27 disposed between the second protrusion 241 and the first protrusion 223. The second heat-conducting layer 26 is provided with a through-hole 261 corresponding to the second protrusion 241. The second protrusion 241 passes through the through-hole 261 and is connected to the first protrusion 225 via the third heat-conducting layer 27. The cooperation between the second protrusion 241 and the first protrusion 223 of the conductive member 24 can thereby improve the heat conduction efficiency of the thermal conductive member 22, thereby improving the efficiency of heat or cold transferred to the conductive member 24. The cooperation between the thermostat 21, the thermal conductive member 22, and the conductive member 24 can achieve uniform heat or cold conduction at every position on the conductive member, thereby improving the user's experience and sense of use of the neck hanging fan.

[0062] In this embodiment, the neck-hanging fan is configured by providing a first protrusion 223 on the side of the heat conducting member 22 proximate to the temperature regulating member 21, thereby enabling the heat conducting member 22 to further contact the temperature regulating member 21, thereby improving heat conduction efficiency and further enhancing the user's sense of use and experience. Furthermore, by providing a conductive member 24 and a second protrusion 241 on the side of the conductive member 24 proximate to the temperature regulating member 21, the conductive member 24 can contact the temperature regulating member through the cooperation of the first protrusion 223 and the second protrusion 241 extending toward the temperature regulating member 21, thereby further improving heat conduction efficiency and enhancing the user's sense of use and experience.

[0063] Please refer to Figures 7 to 11. A portable temperature control device 1 provided in one embodiment of the present invention includes a shell 10 and a temperature control mechanism 202 arranged on the shell 10. The shell 10 includes a main body 203 and a support portion 204. The main body 203 is arranged to form a wearing space 50 for wearing the portable temperature control device 1 on a wearing part such as the neck or waist. The support portion 204 is arranged on a side of the main body 203 close to the wearing space 50, that is, the support portion 204 protrudes from the surface of the main body 203 close to the wearing space 50.

[0064] An air outlet 302 is provided on a side of the main body 203 near the wearing space 50. The air outlet 302 is connected to the wearing space 50, that is, the support portion 204 does not cover or does not completely cover the air outlet 302. The support portion 204 is provided near the air outlet 302, and the temperature control mechanism 202 includes a fan 303 that cooperates with the air outlet 302. When the portable temperature control device 1 is worn at the wearing area, the support portion 204 protrudes from the surface of the main body 203 near the wearing space 50. Therefore, the support portion 204 first contacts the wearing area, thereby separating the area of ​​the main body 203 where the air outlet 302 is provided from the wearing space 50, thereby preventing the skin or clothing at the wearing area from blocking the air outlet 302. When the fan 303 is in operation, the airflow can be discharged from the air outlet 302 and blown toward the wearing area, thereby creating a cooling or warming effect on the wearing area, thereby improving the user experience.

[0065] Specifically, the fan 303 is located inside the main body 203. An air inlet 304 is provided on a side of the main body 203 away from the wearing space 50. The fan 303 is positioned close to the air inlet 304. When the fan 303 is operating, outside air can enter the main body 203 through the air inlet 304, then move toward the air outlet 302 and be blown out from the air outlet 302.

[0066] The main body 203 includes two spaced-apart side arms 161 and a connecting arm 162 connected between the two side arms 161. The two side arms 161 and the connecting arm 162 together enclose a wearing space 50. The ends of the two side arms 161 away from the connecting arm 162 can move relative to each other to adjust the size of the wearing space 50 for user convenience. The support portion 204 and the air outlet 302 are located on the side of the connecting arm 162 near the wearing space 50. When the portable thermostat 1 is worn on the neck, the two side arms 161 are located on the left and right sides of the neck, and the connecting arm 162 is located on the back of the neck. Because the support portion 204 is provided on the side of the connecting arm 162 near the wearing space 50, when assembled, the support portion 204 can separate the air outlet 302 from the back of the neck, allowing air discharged from the air outlet 302 to blow toward the back of the neck, thereby creating a cooling or warming effect on the back of the neck.

[0067] The specific number of the fans 303 is not limited. In this embodiment, two fans 303 are provided in the connecting arm 162 , and the two fans 303 are respectively located at the two ends of the connecting arm.

[0068] It is understandable that the main body 203 and the support portion 204 can be integrally formed or separately formed. In this embodiment, the main body 203 and the support portion 204 are separately formed, and the support portion 204 is made of a flexible material to provide a better wearing experience.

[0069] The support portion 204 includes a cavity 401, whose ends communicate with the air outlet 302 and the wearing space 50, respectively. The axis of the cavity 401 is perpendicular to the axis of the wearing space 50. The airflow generated by the fan 303, after exiting the air outlet 302, first enters the cavity 401, then moves toward the end of the cavity 401 away from the air outlet 302, ultimately passing through the wearer's area, thereby providing a cooling or warming effect on the wearer's area.

[0070] The specific shape of the support portion 204 is not limited. In this embodiment, the support portion 204 is annular and surrounds the outer periphery of the air outlet 302. The support portion 204 forms a cavity 401 inside the support portion to communicate with the air outlet 302. The side of the support portion 204 away from the main body 203 is a concave arc structure. When the portable thermostat 1 is worn at the wearing position, the wearing position is partially located inside the arc structure, creating a certain limiting effect and enhancing stability during use.

[0071] The support portion 204 is provided with a connecting hole 402 that communicates with the cavity 401. The connecting hole 402 is oriented in a different direction from the cavity 401. When the side of the support portion 204 away from the main body 203 is in contact with the wearer's body, the end of the cavity 401 away from the air outlet 302 is blocked by the wearer's body. After entering the cavity 401 from the air outlet 302, the airflow first moves along the direction of the cavity 401, i.e., the axial direction, toward the wearer's body. Once it reaches the wearer's body, it is blocked by the wearer's body and changes direction to be discharged through the connecting hole 402. This avoids the problem of airflow being unable to be discharged after the cavity 401 is blocked, thus affecting the cooling or heating effect.

[0072] The specific location of the communication hole 402 is not limited, as long as it can allow the airflow within the cavity 401 to be discharged. In this embodiment, the support portion 204 is provided with communication holes 402 on opposite sides of the wearing space 50 in the axial direction. After the airflow within the cavity 401 is discharged through the communication holes 402, part of it moves upward along the axial direction of the wearing space 50, and part of it moves downward along the axial direction of the wearing space 50, thereby cooling or heating the areas above and below the wearing area, thereby increasing the cooling or heating area of ​​the portable temperature control device 1.

[0073] In one embodiment, the temperature control mechanism 202 further includes a temperature control element 21 located within the main body 203. The temperature control element 21 is configured to heat or cool the airflow generated by the fan 303. Before the airflow generated by the fan 303 is discharged from the air outlet 302, the temperature control element 21 heats or cools the airflow, generating hot or cold air that is then discharged from the air outlet 302 and blown toward the user, thereby creating a heating or cooling effect.

[0074] In this embodiment, the temperature control element 21 is a semiconductor refrigeration chip. When the semiconductor refrigeration chip is in operation, it generates a cold flow on one side and heat on the opposite side, thereby cooling or heating the air flow. Furthermore, when the direction of the current flowing into the semiconductor refrigeration chip is changed, the direction of the cold flow and heat generated by the semiconductor refrigeration chip is exactly opposite to the original direction.

[0075] The temperature control mechanism 202 also includes a heat conducting member 22 thermally connected to the temperature control member 21, so that heat or cold air generated by the temperature control member 21 is transferred to the temperature conducting member 22. Specifically, when the temperature control member 21 generates cold air on the side close to the temperature conducting member 22, the temperature control member 21 transfers the cold air to the temperature conducting member 22, thereby reducing the temperature of the temperature conducting member 22. When the temperature control member 21 generates heat on the side close to the temperature conducting member 22, the temperature control member 21 transfers the heat to the temperature conducting member 22, thereby increasing the temperature of the temperature conducting member 22. The provision of the temperature conducting member 22 can increase the contact area with the airflow, thereby enhancing the cooling or heating effect on the airflow.

[0076] The temperature regulating member 21 is located on a side of the air outlet 302 away from the wearing space 50 and spaced apart from the air outlet 302. The temperature conducting member 22 is located between the temperature regulating member 21 and the air outlet 302. Before being discharged from the air outlet 302, the airflow first passes through the temperature conducting member 22, exchanging heat with the airflow, thereby heating or cooling the airflow to form hot air or cold air.

[0077] Specifically, the thermal conductive element 22 includes a base plate 501 thermally connected to the thermostat 21 and a thermal conductive plate 502 disposed on a side of the base plate 501 away from the thermostat 21. There are multiple thermal conductive plates 502, which are spaced apart from each other. A first air duct 506 is formed between two adjacent thermal conductive plates 502, and the air outlet 302 is connected to the first air duct 506. Both the base plate 501 and the thermal conductive plate 502 are made of a thermally conductive material such as copper or aluminum, allowing heat or cold air generated by the thermostat 21 to be transferred to the base plate 501 and the thermal conductive plate 502. The airflow generated by the fan 303 can enter the first air duct 506, where it comes into contact with the thermal conductive plate 502 and the base plate 501, further increasing the contact area with the airflow. After cooling or heating the airflow through the base plate 501 and the thermal conductive plate 502, the airflow is discharged from the air outlet 302.

[0078] The main body 203 includes an air outlet plate 503 located near the wearing space 50. The air outlet 302 extends through the air outlet plate 503, and the thermal conductor 22 is thermally connected to the air outlet plate 503. The air outlet plate 503 is made of a thermally conductive material. The heat or cold air generated by the thermostat 21 can be transferred to the air outlet plate 503 through the thermal conductor 22. When the airflow is discharged from the air outlet 302, it will flow through the air outlet plate 503. Therefore, the heat or cold air generated by the thermostat 21 is transferred to the air outlet plate 503, further increasing the contact area with the airflow and improving the heat exchange effect. Specifically, the thermal conductor 22 and the air outlet plate 503 are integrally formed.

[0079] The fan 303 includes fan blades 244 and a casing 242. The fan blades 244 are rotatably installed inside the casing 242. The casing 242 is located on the outside of the heat conduction plate 502. The casing 242 is separated from the air outlet plate 503, thereby forming a second air duct 243 between the casing 242 and the air outlet plate 503. The second air duct 243 is located on one side of the first air duct 506 and is connected to the first air duct 506. A part of the air outlet 302 on the air outlet plate 503 is connected to the first air duct 506, and the other part is connected to the second air duct 243. The airflow generated by the fan 303 first enters the first air duct 506, and after flowing through the heat conduction plate 502, a part of it is discharged from the air outlet 302 connected to the first air duct 506, and the other part does not have time to be discharged and thus changes the flow direction, enters the second air duct 243, and is blown out from the air outlet 302 connected to the second air duct 243, thereby increasing the air outlet area of ​​the portable temperature control device 1 so that more parts can be cooled or heated.

[0080] In this embodiment, the air outlet plate 503 is long and curved, the thermal conductor 22 is connected to the middle region of the air outlet plate 503, and the fans 303 are located at the ends of the air outlet plate 503. Specifically, the first air duct 506 is located in the middle region of the air outlet plate 503, and the second air duct is located at the ends of the air outlet plate 503. Specifically, there are two fans 303 within the connecting arm 162, one at each end of the air outlet plate 503, thereby forming two second air ducts 243 at each end of the air outlet plate 503, with the first air duct 506 located between the two second air ducts 243.

[0081] In one embodiment, a radiator 40 is provided on the side of the thermostat 21 facing away from the thermal conductor 22. A heat dissipation vent 505 is provided on the side of the main body 203 facing away from the wearing space 50, cooperating with the fan 303. The radiator 40 is positioned proximate to the heat dissipation vent 505. The radiator 40 absorbs heat or cold air generated on the side of the thermostat 21 facing away from the thermal conductor 22, thereby improving the cooling or heating efficiency on the side of the thermostat 21 facing toward the thermal conductor 22, thereby enhancing the cooling or heating effect on the wearer's body. Furthermore, a portion of the airflow generated by the fan 303 flows through the thermal conductor 22, exchanges heat with the thermal conductor 22, and is then discharged from the air outlet 302. The remaining portion flows through the radiator 40, exchanges heat with the radiator 40, and is then discharged from the heat dissipation vent 505. Because the heat dissipation vent 505 is located away from the wearing space 20, the airflow discharged from the heat dissipation vent 505 after heat exchange with the radiator 40 does not blow toward the wearer's body, thereby preventing it from affecting the cooling or heating effect on the wearer's body.

[0082] Specifically, the radiator 40 is a fin-type radiator to increase the contact area with the air.

[0083] The main body 203 is provided with a mounting frame 601. Mounting locations 602 are located on opposite sides of the mounting frame 601. The two mounting locations 602 are spaced apart from each other, and the thermal conductive element 22 and the heat sink 40 are mounted in corresponding mounting locations 602. Specifically, the mounting frame 601 is annular in shape, with the thermostat 21 located inside the mounting frame 601 and sandwiched between the thermal conductive element 22 and the heat sink 40. Mounting the thermal conductive element 22 and the heat sink 40 on opposite sides of the mounting frame 601 prevents contact between the thermal conductive element 22 and the heat sink 40.
