DETAILED DESCRIPTION

[0066] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0067] An embodiment of the present invention provides a portable fan 10, which can be a temperature control device that can be worn on different parts of the user's body, such as a temperature control device worn on the user's wrist, a temperature control device worn on the user's waist, or a temperature control device worn on the user's neck. In the embodiment of the present application, for ease of understanding, the portable wearable fan is described as a neck-worn fan as an example.

[0068] As shown in FIG. 1 and FIG. 2 , the portable fan provided by the embodiment of the present invention includes, for example, a housing 100 , a partition bracket 200 , a temperature adjustment assembly 300 , a temperature conducting member 400 and a first blowing device 500 .

[0069] Specifically, the housing 100 has, for example, a housing cavity 101, a first air outlet 104, and a heat dissipation vent 105. The housing 100 is formed with, for example, a wearing space 130, which allows the portable fan 10 to be worn on the neck of a human body. The housing 100 includes, for example, a first housing 110 and a second housing 120 arranged opposite to each other. The first housing 110 is arranged close to the wearing space 130, and the second housing 120 is connected to a side of the first housing 110 away from the wearing space 130. The first housing 110 and the second housing 120 are connected and enclosed to form the housing cavity 101. The first air outlet 104 is, for example, arranged on the first housing 110 or at the connection between the first housing 110 and the second housing 120. The heat dissipation vent 105 is, for example, arranged on the second housing 120. The specific positions of the first air outlet 104 and the heat dissipation vent 105 are not limited here.

[0070] As shown in Figure 5, the partition bracket 200 is, for example, arranged in the shell 100 and divides the accommodating chamber 101 into a first accommodating chamber 102 close to the wearing space 130 and a second accommodating chamber 103 away from the wearing space 130. The first air outlet 104 is connected to the first accommodating chamber 102, and the heat dissipation port 105 is connected to the second accommodating chamber 103. The partition bracket 200 is used to place the temperature control component 300 and other components and is used to divide the accommodating chamber 101 in the shell 100 into two parts, so that after the temperature control component 300, the temperature conducting component 400, etc. are installed on the partition bracket 200, the air flow is discharged from the first air outlet 104 and the heat dissipation port 105 respectively.

[0071] The temperature control component 300 is, for example, a TEC (Thermoelectric cooler) or other semiconductor refrigeration sheet, which generates a cooling effect through the action of electric current, and is energy-saving, environmentally friendly, small in size, and has a good cooling effect. The temperature control component 300, for example, passes through the partition bracket 200, so that the surface of the temperature control component 300 is exposed to the partition bracket 200, and preferably, in the first direction, the ratio of the positive projection area of ​​the temperature control component 300 on the partition bracket 200 to the area of ​​the partition bracket 200 is greater than or equal to 1 / 2, wherein the first direction is the thickness direction of the shell 100. In this embodiment, by lengthening the temperature control component 300, the cooling area of ​​the temperature control component 300 is increased, the cooling effect is better, and the user can have a more comfortable experience during use.

[0072] The thermal conductive member 400 is, for example, disposed within the first accommodating chamber 102 and thermally connected to the thermostat assembly 300. The thermal conductive member 400 is made of a metal material such as aluminum alloy or copper and is, for example, fin-shaped or in another shape, for transferring the cooling energy generated by the thermostat assembly 300 to the airflow, thereby enhancing the cooling effect.

[0073] Specifically, the first blowing device 500 is used to blow air. The air blown by the first blowing device 500 is, for example, connected to the first accommodating chamber 102, and is used to guide the airflow generated by the first blowing device 500 to the outside through the first air outlet 104 via the heat conducting member 400. At the same time, the air blown by the first blowing device 500 can also be connected to the second accommodating chamber 103, and the airflow is guided to the outside through the heat dissipation port 105 to remove the heat generated by the temperature regulating component 300 during operation and blown out from the heat dissipation port 105 to ensure that the heat generated by the temperature regulating component 300 during operation is dissipated in a timely manner, so that the temperature regulating component 300 maintains normal operation and ensures the cooling effect of the portable fan 10. In some embodiments, as shown in Figure 5, the first blowing device 500 includes, for example, a first fan 501 for blowing air. The air blown by the first fan 501 is, for example, connected to the first accommodating chamber 102 and the second accommodating chamber 103, and is used to guide the airflow generated by the first fan 501 to the outside through the first air outlet 104 and the heat dissipation port 105 respectively via the heat conducting member 400. Among them, as shown in Figures 1 and 2, the first air outlet 104 can be used, for example, as an outlet for blowing air toward the human body, that is, the first air outlet 104 can be used to discharge the airflow generated by the first blowing device 500 after heat exchange through the heat conducting member 400, and can be blown to the face or neck and other parts of the human body. When the user only needs the wind blown by the portable fan 10 to blow to the face or neck and other parts, the position and air outlet direction of the first air outlet 104 can meet the user's blowing needs. In other embodiments, according to the actual needs of the user, the first air outlet 104 can be set at other positions of the housing 100, which is not limited here. As shown in Figures 1 and 2, the heat dissipation port 105 is, for example, an air outlet that can be used for heat dissipation. The wind generated by the first blowing device 500 can take away the heat generated by the temperature control component 300 when it is working and discharge it through the heat dissipation port 105. In this embodiment, since the heat dissipation vent 105 is used to dissipate heat generated by the operation of the thermostat 310, the heat dissipation vent 105 cannot be positioned toward the human body. Therefore, the heat dissipation vent 105 is positioned on the outer side of the housing 100, facing away from the wearable space 130. This allows for heat dissipation away from the human body, ensuring that the heat dissipation vent 105 does not affect the cooling experience, thereby enhancing the user's cooling experience. In some embodiments, there is no need for a blower to blow air into the second accommodating chamber 103. Heat within the second accommodating chamber 103 is discharged through the heat dissipation vent via heat exchange with air.

[0074] In the embodiment of the present invention, a partition bracket 200 is provided to separate the accommodating chamber 101 in the shell 100 into a first accommodating chamber 102 and a second accommodating chamber 103, and the thermal conductive component 400 is connected to the temperature regulating component 300 by heat conduction. A portion of the airflow blown out from the first air outlet 104 by the first blowing device 500 flows through the thermal conductive component 400 in the first accommodating chamber 102, and the thermal conductive component 400 transfers the cooling capacity generated by the temperature regulating component 300 to the airflow. The airflow exchanges heat with the thermal conductive component 400, so that the airflow can be quickly cooled and blown out from the first air outlet 104. In addition, in this embodiment, the temperature regulating component 300 is lengthened, the cooling area of ​​the temperature regulating component 300 is increased, the cooling effect is better, and the user can get a more comfortable experience during use.

[0075] As shown in Figures 2, 5, and 6, the thermostat assembly 300 includes, for example, a plurality of thermostats 310, such as at least two thermostats 310. The plurality of thermostats 310 are arranged on the partition bracket 200 along the length direction of the housing 100 (i.e., the length direction of the partition bracket 200). The housing 100 is configured to fit the shape of a human neck, for example. The plurality of thermostats 310 are arranged along the length direction of the housing 100 so that the arrangement direction of the plurality of thermostats 310 on the partition bracket 200 is substantially consistent with the wind direction, effectively utilizing space. The above design allows for the arrangement of more thermostats 310, resulting in a greater cooling capacity and better cooling effect. Of course, in other embodiments, the thermostat assembly 300 may also include only one thermostat 310.

[0076] As shown in FIG2 , an angle is formed between two adjacent temperature-regulating elements 310 , that is, at least one group of two adjacent temperature-regulating elements 310 among the multiple temperature-regulating elements 310 are not arranged in a straight line, but are set at an angle, so that in the same space, the two temperature-regulating elements 310 set at an angle can be arranged in a longer area, so that the heat conducting element 400 can also be arranged in a longer area, thereby increasing the total temperature-regulating area through which the wind passes, and the cooling capacity is greater, thereby achieving a better cooling effect.

[0077] Specifically, as shown in FIG6 , the thermal conductive element 400 includes, for example, a mounting portion 401 and a thermal conductive body 402. The mounting portion 401 is provided with a bent portion 403. The mounting portion 401 is, for example, a bent thermal conductive sheet or a bent shape formed by splicing two thermal conductive sheets. The mounting portion 401 is made of, for example, a metal material such as aluminum alloy or copper. The bent portion 403 is located between the two temperature control elements 310 formed at an angle. The mounting portion 401 thermally connects the multiple temperature control elements 310, allowing the thermal conductive element 400 to be closely aligned with the multiple temperature control elements 310, thereby improving the heat conduction effect between the thermal conductive element 400 and the multiple temperature control elements 310. The thermal conductive body 402 includes a plurality of thermal conductive fins, which are spaced apart to form a channel for airflow to flow through and cool down. The thermal conductive body 402 is, for example, connected to the side of the mounting portion 401 facing away from the temperature control assembly 300 and is, for example, made of a metal material such as aluminum alloy or copper.

[0078] In some embodiments, the first blowing device 500 includes, for example, a first fan 501, and the first fan 501 is, for example, a double-layer structure. Specifically, the first fan 501 includes, for example, a first blade 510, a second blade 520, and an isolation plate 530. The first blade 510 is, for example, arranged corresponding to the first accommodating chamber 102. The first blade 510 is used to generate an airflow that flows into the first accommodating chamber 102 and flows through the heat conducting member 400 and is blown out from the first air outlet 104, so that the airflow generated by the first blade 510 is effectively cooled, thereby enhancing the cooling effect of the portable fan 10. The second blade 520 is, for example, arranged corresponding to the second accommodating chamber. The airflow generated by the second blade 520 flows into the second accommodating chamber 103 and is guided outward by the heat dissipation port 105 to dissipate the heat generated when the thermostat 310 is working. The isolation plate 530 is, for example, arranged between the first fan blade 510 and the second fan blade 520. The isolation plate 530 is, for example, in a circular shape. The isolation plate 530 is aligned with the partition bracket 200. The isolation plate 530 helps to separate the airflow, ensuring that the two airflows flowing into the first accommodating chamber 102 and the second accommodating chamber 103 respectively do not interfere with each other, while improving the stability of the internal structure of the first fan 501.

[0079] In another embodiment, the first blowing device 500 includes, for example, two independently arranged fans, the two fans corresponding to the first accommodating chamber 102 and the second accommodating chamber 103, respectively. Specifically, the first blowing device 500 includes, for example, a first fan (not shown in the figure) and a second fan (not shown in the figure) arranged opposite to each other. The first fan is, for example, arranged corresponding to the first accommodating chamber 102. The airflow generated by the first fan flows into the first accommodating chamber 102, flows through the thermal conductive member 400 for heat exchange, and is blown out from the first air outlet 104. This effectively cools the air generated by the first fan, thereby enhancing the cooling effect of the portable fan 10. The second fan is, for example, arranged corresponding to the second accommodating chamber 103. The airflow generated by the second fan flows into the second accommodating chamber 103 and is guided outward by the heat dissipation outlet 105 to dissipate the heat generated by the thermostat 310 during operation.

[0080] Specifically, the thermostat assembly 300, for example, has a cooling end and a heat dissipation end that are opposite each other. The cooling end is located on a side of the thermostat assembly 300 that is close to the first accommodating chamber 102. The thermal conductive element 400 is thermally connected to the cooling end of the thermostat assembly 300, as shown in Figures 3, 5, and 6. A heat dissipation assembly 700 is provided in the second accommodating chamber 103, and the heat dissipation assembly 700 is thermally connected to the heat dissipation end of the thermostat assembly 300, for example. Of course, in other embodiments, the thermal conductive element can also be thermally connected to the heat dissipation end of the thermostat assembly 300, so that the air blown out from the first air outlet 104 is hot air, making it convenient for users to use a portable fan for heating in winter.

[0081] In this embodiment, the heat conduction connection refers to direct contact between two objects to form heat transfer, or indirect contact to form heat transfer. In some embodiments, the portable fan 10 further includes a heat conduction structure, which is disposed, for example, between the thermostat assembly 300 and the heat dissipation assembly 700. The heat conduction structure is made of an intermediate heat conduction medium such as thermal grease, silica gel, or graphite, and is used to enable indirect contact between the thermostat assembly 300 and the heat conduction member 400, or between the thermostat assembly 300 and the heat dissipation assembly 700, to form heat transfer.

[0082] In some embodiments, the portable fan 10 further includes, for example, a second blowing device 600, which is disposed within the second accommodating chamber 103. The second blowing device 600 is configured to discharge heat generated by the thermostat assembly 300 through the heat dissipation assembly 700 and the heat dissipation vent 105. This allows the heat generated by the thermostat assembly 300 to be dissipated more promptly during operation, allowing the thermostat assembly 300 to maintain normal operation and ensure the cooling effect of the portable fan 10. The second blowing device 600 and the first blowing device 500 are, for example, respectively disposed at opposite ends of the partition bracket 200. The first blowing device 500 and the second blowing device 600 blow air to the heat dissipation assembly 700 located between the first blowing device 500 and the second blowing device 600.

[0083] Specifically, the heat dissipation assembly 700 is, for example, located within the second accommodating cavity 103 and disposed between the heat dissipation port 105 and the second blowing device 600. The heat dissipation assembly 700 is disposed corresponding to the temperature control assembly 300. The heat dissipation assembly 700 is, for example, made of a metal material such as aluminum alloy or copper, and is, for example, fin-shaped or in another shape, and is used to transfer heat generated by the temperature control assembly 300 to the airflow, thereby dissipating the heat generated by the temperature control assembly 300 more promptly.

[0084] Specifically, the heat dissipation component 700 includes, for example, multiple (at least two) heat dissipation elements 701 and a substrate 702. Each heat dissipation element is located on the substrate 702. The substrate 702 is in the form of a sheet and can be provided with one or more heat dissipation elements. When there is only one substrate 702, multiple heat dissipation elements are provided on the substrate 702. When multiple substrates 702 are provided, one heat dissipation element 701 can be provided corresponding to one substrate 702. The substrate 702 is thermally conductively connected to the temperature control component 300, so that the multiple heat dissipation elements 701 are respectively thermally conductively connected to the temperature control component 300. The heat dissipation element 701 is composed of multiple heat dissipation fins. A heat dissipation channel is formed between each two adjacent heat dissipation fins. The substrate 702 and the heat dissipation element 701 are made of, for example, a material with high thermal conductivity such as aluminum alloy or copper, wherein the space between the two adjacent heat dissipation elements 701 is large. A partition 703 is provided; the partition 703 is provided corresponding to the heat dissipation port 105. In some embodiments, as shown in Figures 4, 7 and 8, a partition 703 is provided between two adjacent heat dissipation members 701 that are arranged at an angle among the multiple heat dissipation members 701. The partition 703 is, for example, an integrally formed structure with the substrate 702. The partition 703 extends along the substrate toward the heat dissipation port 105. The partition 703 is located between the heat dissipation channels of the two adjacent heat dissipation members 701 and is used to separate the airflow in the heat dissipation channels of the two adjacent heat dissipation members 701, ensuring that the airflow blown out by the first blowing device 500 and the second blowing device 600 can be blown out from the heat dissipation port 105 in time after passing through the heat dissipation assembly 700, so that the two airflows will not collide and can be discharged more smoothly from the heat dissipation port 105. In other embodiments, at least one of the two adjacent heat sinks 701 that are angled may have a partition 703 formed at its end near the other heat sink 701, that is, the partition 703 is directly integrally formed at the end of the heat sink 701, and can also separate the airflow flowing through the two heat sinks 701 so that it can be discharged from the heat dissipation port 105 in a timely manner.

[0085] It should be noted that the number of the above-mentioned heat dissipation components 701 and thermal conductive components 400 can be set according to the number of temperature regulating components 310. The number of temperature regulating components 310 can be set according to the actual structure of the product and user needs, and is not limited here.

[0086] It should be noted that the first blowing device 500 and the second blowing device 600 may be, for example, a centrifugal turbofan, a diagonal flow fan, an axial flow fan or other fans of the prior art, which are not specifically limited here.

[0087] The partition bracket 200 includes a partition 210 and two side panels 220, and the accommodating cavity 101 is separated by the partition 210. The two side panels 220 extend along the length direction of the shell 100 and are arranged on the upper and lower sides of the partition 210, and the partition 210 is connected to the middle part of the side panels 220 (that is, not completely at the edge of the side panels). The temperature control component 300 is arranged on the partition 210, and the heat conducting component 400 and the heat dissipation component 700 are respectively arranged on the left and right sides of the partition 300, and the heat conducting component 400 and the heat dissipation component 700 are both arranged between the two side panels 220, so that the side panels 220 can wrap the heat conducting component 400 and the heat dissipation component 700 up and down on the upper and lower sides of the partition 210, which is convenient for installation and fixation.

[0088] 2 , the partition bracket 200 further includes an air guide 230 , which is fixedly connected to a side of the partition 210 close to the heat conducting member 400 , or is arranged on a side of the first shell 110 close to the heat conducting member 400 . The air guide 230 is, for example, two air guide plates 231 arranged opposite to each other as shown in FIG. 2 , and an air outlet duct is formed between the two air guide plates 231 , the partition bracket 200 and the first shell 110 . The air guide 230 extends from the position where the temperature regulating member 310 is installed on the partition bracket 200 to the position where the partition bracket 200 is close to the first air outlet 104 , that is, the air guide 230 is located at one end of the heat conducting member 400 away from the first blowing device 500 . The air guide 230 is used to guide the wind generated by the first blowing device 500 to be blown out through the air outlet duct to the first air outlet 104 , so that the cooled wind is blown out from the first air outlet 104 in the extension direction of the air guide 230 , thereby further improving the cooling effect.

[0089] In some embodiments, as shown in Figure 3, a guide member 111 is provided on the partition bracket 300, for example. The guide member 111 is provided on the side of the first blowing device 500 close to the heat dissipation assembly 700, for example. The guide member 111 is a baffle as shown in Figure 3, and the guide member 111 extends obliquely along the direction of the first blowing device 500 toward the heat dissipation assembly 700. The guide member 111 is used to guide and divert the wind blown out by the first blowing device 500 and directed to the heat dissipation assembly 700 and blow it out from the heat dissipation port 105, preventing the airflow generated by the first blowing device 500 from blowing all to one side, so that the airflow blown out by the first blowing device 500 flows evenly to the heat dissipation assembly 700, increasing the contact area between the airflow and the heat dissipation assembly 700, and further improving the heat dissipation effect.

[0090] As shown in FIG5 , the portable fan 10 further includes a power supply 900, which is used to provide power to the portable fan 10. The power supply 900 can be, for example, a battery or other type of battery. The first blowing device 500 can also be used to dissipate heat generated by the power supply 900 through the first air outlet 104, thereby preventing overheating and extending the service life of the power supply 900.

[0091] As shown in Figures 1 and 3, the housing 100 is further provided with a plurality of air inlets, which are respectively provided in correspondence with the first blowing device 500 and the second blowing device 600. The plurality of air inlets include a first air inlet 106 and a second air inlet 107 provided at the upper and lower ends of the first blowing device 500 and communicating with the first accommodating chamber 102, and a third air inlet 108 provided at the second blowing device 600 and communicating with the second accommodating chamber 103. In this embodiment, the air inlets may be provided at both ends of each blowing device or at one end of the blowing device, and the specific details are not limited here.

[0092] Referring to Figures 9 to 16 , the present application provides a portable fan 10 comprising a housing 100, a thermostat 310, a heat conducting member 400, and a second blowing device 600. The housing 100 is provided with a first air inlet 106; the thermostat 310 is disposed within the housing 100, and the heat conducting member 400 is disposed within the housing and connected to the thermostat 310; the second blowing device 600 is disposed within the housing 100, with the heat conducting member 400 located between the second blowing device 600 and the first air inlet 106. When the second blowing device 600 is in operation, air can be drawn into the housing 100 through the first air inlet 106 and contact the heat conducting member 400 to be cooled or heated. It is understood that the connection between the heat conducting member 400 and the thermostat 310 can be direct or indirect, so as to facilitate heat or cold conduction between the heat conducting member 400 and the thermostat 310.

[0093] Compared with the traditional method of blowing air at high speed to the temperature guide member 400 through a fan, in this embodiment, air is sucked into the shell 100 by suction. When the second blowing device 600 starts working, the pressure in the shell 100 decreases, and the outside air is sucked in from the first air inlet 106. Since the temperature guide member 400 in this application is arranged between the second blowing device 600 and the first air inlet 106, when the air is sucked in from the first air inlet 106, compared with the high-speed flow through the temperature guide member 400 in the traditional method, this embodiment does not provide a blowing force between the first air inlet 106 and the temperature guide member 400. Therefore, the air in this embodiment can flow to the temperature guide member 400 relatively slowly, so that it can fully contact the temperature guide member 400, further allowing the air to be cooled or heated more evenly before flowing to the second blowing device 600. At this time, it is accelerated by the second blowing device 600 and blown out of the shell 100, so that the temperature of the cooled or heated air blown out of the shell 100 is more uniform, thereby improving the user experience. It is understood that, in one embodiment, the heat conducting member 400 may be a cold distributing member. In this embodiment, when the second blowing device 600 starts working, outside air is sucked in from the first air inlet 106 and flows through the cold distributing member. After fully contacting the cold distributing member, the air is blown out of the housing 100 through the second blowing device 600. In summary, the air blown out of this embodiment is fully contacted with the cold distributing member in the housing 100 and cooled, so it can be blown out of the housing 100 more evenly. In another embodiment, the heat conducting member 400 may be a heat distributing member. In this embodiment, when the second blowing device 600 starts working, outside air is sucked in from the first air inlet 106 and flows through the heat distributing member. After fully contacting the heat distributing member, the air is blown out of the housing 100 through the second blowing device 600. In summary, the air blown out of this embodiment is fully contacted with the heat distributing member in the housing 100 and heated, so it can be blown out of the housing 100 more evenly.

[0094] In some embodiments, referring to Figures 10 and 14, the portable fan 10 further includes a partition bracket 200, which is disposed in the shell 100 to separate the cavity in the shell 100 into a first air duct 12, and the second blowing device 600 and the heat conducting member 400 are disposed in the first air duct 12. The first air inlet 106 is connected to the first air duct 12. When the second blowing device 600 is working, air can be sucked into the first air duct 12 through the first air inlet 106. In this embodiment, after the air is sucked into the first air duct 12 from the first air inlet 106, compared with the traditional method of flowing through the heat conducting member 400 at high speed, this embodiment does not provide a blowing force between the first air inlet 106 and the heat conducting member 400, so that the air in this embodiment can flow toward the heat conducting member 400 relatively slowly, so that it can fully contact the heat conducting member 400, further allowing the air to be cooled or heated more evenly before flowing to the second blowing device 600, and then accelerated by the second blowing device 600 and blown out of the first air duct 12.

[0095] In another embodiment, the temperature conducting member 400 is connected to the cold end 21 of the temperature regulating member 310, the portable fan 10 further includes a first blowing device 500, the first blowing device 500 is, for example, a centrifugal fan, the partition bracket 200 further separates the cavity in the shell into a second air duct 13, the second air duct 13 is spaced apart from the first air duct 12, the portable fan 10 further includes a first blowing device 500 and a heat dissipation assembly 700, the first blowing device 500 and the heat dissipation assembly 700 are arranged in the second air duct 13, the heat dissipation The component 700 is connected to the hot end 22 of the temperature control component 310, the shell 100 is provided with a second air inlet 107, the second air inlet 107 is connected to the second air duct 13, the hot end 22 of the temperature control component 310 faces the second air duct 13, the heat dissipation component 700 is accommodated in the second air duct 13, and the first blowing device 500 is located between the second air inlet 107 and the heat dissipation component 700. When the first blowing device 500 is working, the first blowing device 500 can blow the air coming in from the second air inlet 107 toward the heat dissipation component 700. In this embodiment, air is blown through the second air duct 13. The first blowing device 500 is disposed between the heat dissipation assembly 700 and the second air inlet 107. When air enters through the second air inlet 107, the first blowing device 500 blows the air toward the heat dissipation assembly 700, causing the air to pass through the heat dissipation assembly 700 at high speed, thereby carrying the heat within the second air duct 13 out of the housing 100. This prevents excessive heat within the second air duct 13 from affecting the temperature control effect of the thermostat 310, such as the cooling effect at the cold end 21 of the thermostat 310. In this embodiment, the heat within the second air duct 13 is quickly blown out of the housing 100, thereby improving the temperature control effect of the thermostat 310.

[0096] In some embodiments, the shell 100 includes a connecting section 14 and an extension section 15 provided at both ends of the connecting section 14, the connecting section 14 and the two extension sections 15 enclose a wearing space 130, and the connecting section 14 and / or the two extension sections 15 are provided with a temperature regulating component 1, a temperature conducting component 400 and a second blowing device 600. In combination with the foregoing, on the other hand, it can be understood that the position of the first air duct 12 can be flexibly set. For a wearable fan, such as a neck hanging fan, the first air duct 12 can be set at a position facing the neck or cheek. For example, the shell 100 may include a connecting section 14 and an extension section 15 provided at both ends of the connecting section 14, the connecting section 14 and the extension section 15 enclose a wearing space 130, and the partition bracket 200 includes a plurality of brackets, two of which are respectively provided at the extension section 15 to divide the cavity in the extension section 15 into the first air duct 12 and the second air duct. 13, the first air duct 12 is close to the wearing space 130, and the second air duct 13 is away from the wearing space 130, so that the air cooled or heated by the thermal conductive element 400 can be blown toward the wearing space 130. The wearing space 130 can be worn on the user's wrist, neck, or even leg. For a handheld fan, the first air duct 12 can be set on the side facing the user. For example, the housing 100 includes a main body and a handheld section connected to the main body, and the partition bracket 200 is set on the main body to divide the cavity of the main body into the first air duct 12 and the second air duct 13. The user can hold the handheld section and point the main body toward the place where air is needed, so that the cooling or heating of the thermal conductive element 400 can be blown to the user.

[0097] In some embodiments, the first air duct 12 includes a first air guide channel 121, a second air guide channel 122, a third air guide channel 123, and an air outlet channel 1211. Referring to FIG. 10 , in this embodiment, the housing 100 is further provided with a first air outlet 104. The first air duct 12 connects the first air inlet 106 and the first air outlet 104. The second blowing device 600 is, for example, a centrifugal fan. A first air guide portion 41 is provided on the side of the partition bracket 200 facing the first air duct 12. The first air guide portion 41 is provided around the outside of the second blowing device 600 to form the first air guide channel 121. Air cooled or heated by the heat conducting member 400 can flow out of the first air outlet 104 through the first air guide channel 121. This arrangement can guide the cold air or hot air blowing toward the second blowing device 600, ensuring that it can flow out of the first air outlet 104. On the other hand, the presence of the first air guide portion 41 can change the direction of air flow, so that the first air outlet 104 can be set according to the needs of the user, so as to reasonably and effectively utilize the space inside the housing 100. In more detail, please refer to Figures 12 and 14. In this application, a second air guide portion 42 and a partition portion 44 are further provided on the side of the partition bracket 200 facing the first air duct 12. The partition portion 44 is connected to the first air guide portion 41, and a second air guide channel 122 is formed between the partition portion 44 and the second air guide portion 42. The partition portion 44 is also provided with a vent 441 to connect the first air guide channel 121 and the second air guide channel 122, so that the air cooled or heated by the temperature conducting member 400 can enter the first air guide channel 121 through the second air guide channel 122. With this arrangement, after being cooled or heated by the temperature conducting member 400, the outside air can directly enter the first air guiding channel 121 through the second air guiding channel 122, thus preventing overflow. This improves the structural compactness of the housing 100, greatly ensuring the effective realization of the temperature control effect and improving the space utilization rate within the housing 100. The cooled or heated air flows through the second air guiding channel 122 to the first air guiding channel 121 and then to the air inlet side of the second blowing device 600, allowing the cooled or heated air to be effectively blown out of the first air outlet 104 of the housing 100 through the air outlet side of the second blowing device 600.

[0098] Further, referring to Figures 12 and 14, the partition bracket 200 is further provided with a third air guide portion 43. One end of the third air guide portion is connected to the second air guide portion 42, and the other end extends obliquely toward the partition portion 44 and / or the first air guide portion 41 to form a third air guide channel 123. The third air guide channel 123 is connected to the second air guide channel 122, so that the air cooled or heated by the thermal conductive member 400 can enter the second air guide channel 122 through the third air guide channel 123. In this embodiment, the oblique extension of the third air guide portion 43 can guide the flow of the cooled or heated air, thereby directing the cooled or heated air to the second air guide channel 122, thereby fully utilizing the space within the housing 100.

[0099] Furthermore, referring to Figure 10 , a fourth air guide portion 17 is provided on the side of the housing 100 facing the first air duct 12. The fourth air guide portion 17 is located on the side of the heat conducting member 400 near the first air outlet 104, thereby dividing the cavity within the housing 100 into an air outlet channel 1211. The air outlet channel 1211 is respectively connected to the first air guide channel 121 and the first air outlet 104. In this embodiment, the cooled or heated air entering the first air guide channel 121 is blown out of the housing 100 through the first air outlet 104 along the air outlet channel 1211 under the action of the first air guide portion 41, the second air guide portion 42, the third air guide portion 43, and the fourth air guide portion 17. In this embodiment, the air outlet 1211 can be located at the top of the thermal conductive member 400, which not only fully utilizes the space within the housing 100, but also, because the air outlet 1211 is adjacent to the thermal conductive member 400, the thermal conductive member 400 can re-cool or re-heat the air in the air outlet 1211, thereby improving the temperature control effect. It is understood that in one embodiment, the fourth air guide portion 17 can be made of a conductive material to facilitate further temperature control.

[0100] Referring to FIG. 10 , the present application includes multiple first air outlets 104. The portable fan 10 also includes at least one diverter 7 , which is disposed in the air outlet channel 1211 to divert air from the outlet of the first air guide channel 121 to each of the first air outlets 104 via the air outlet channel 1211. Cooled or heated air can be blown out of the housing 100 through the multiple first air outlets 104. This arrangement ensures that the cool or heated air flowing out of the multiple first air outlets 104 is uniform and smooth, thereby improving user comfort.

[0101] Further, referring to Figures 15-16, the thermal conductive member 400 includes a mounting portion 401 and a plurality of energy dissipating fins 232. The plurality of energy dissipating fins 232 are disposed on a side of the mounting portion 401 facing away from the cold end 21 of the thermostat 310 and housed within the first air duct 12. The mounting portion 401 is disposed at the cold end 21 of the thermostat 310 and is at least partially exposed to at least one of the first air guide channel 121 and the air outlet channel 1211. In this embodiment, the mounting portion 401 is disposed at the cold end 21 of the thermostat 310 and is exposed to both the first air guide channel 121 and the air outlet channel 1211 to further cool the air flowing along the airflow path until the air flows out of the first air outlet 104 to form cold air.

[0102] Similarly, within the second air duct 13, the heat dissipation assembly 700 includes a substrate 702 and a heat sink 242. The heat sink 242 is disposed on a side of the substrate 702 facing away from the hot end 22 and is housed within the second air duct 13. The substrate 702 is disposed at the hot end 22 of the temperature control element 310 and may be at least partially exposed to the second air duct 13. With this arrangement, when the first blowing device 500 begins operating, air flowing through the second air duct 13 can also carry heat from the substrate 702 out of the second air duct 13, thereby improving the cooling effect of the portable fan 10.

[0103] Furthermore, a fifth air guide portion 45 is provided on the side of the partition bracket 200 facing the second air duct 13, and the fourth air guide portion 45 is located on the outside of the first blowing device 500 to form a heat dissipation channel 131 in the second air duct 13, thereby blowing the wind force of the first blowing device 500 toward the heat dissipation component 700, so that the flowing air quickly takes away the heat in the second air duct 13, and further blows out from the heat dissipation port 132 opened in the second air duct 13.

[0104] As shown in Figures 17 and 18 , an embodiment of the present invention provides a portable fan 10. The portable fan 10 is, for example, a neck hanging fan, etc. Specifically, the portable fan 10 includes, for example, a housing 100, a first blowing device 500, and a heat conducting member 400.

[0105] Specifically, as shown in Figures 17 and 18 , the housing 100 is made of, for example, metal or plastic. The housing 100 is provided with a first air outlet 104 and a first air inlet 106, as well as a first air duct cavity communicating with the first air outlet 104 and the first air inlet 106. The first blowing device 500 is, for example, a centrifugal fan. The first blowing device 500 is disposed within the first air duct cavity. The heat conducting member 400 is disposed within the first air duct cavity, between the first blowing device 500 and the first air outlet 104.

[0106] Furthermore, as shown in Figures 18 and 19, the end of the heat conducting member 400 that is close to the first blowing device 500 is the air inlet end 320, and the end of the heat conducting member 400 that is away from the first blowing device 500 is the air outlet end 330. The heat conducting member 400 is formed, for example, by a plurality of air guide fin groups arranged in sequence, for example, by two, three, four or more air guide fin groups arranged in sequence. The air outlet ends 330 of the plurality of air guide fin groups are distributed in a stepped manner from away from the first air outlet 104 to closer to the first air outlet 104. Each air guide fin group includes at least one energy dissipating fin 232, and an air flow channel is formed between each two adjacent energy dissipating fins 232. Specifically, in this embodiment, the air outlet ends 330 of the heat conducting member 400 are distributed in a stepped manner, that is, the air outlet ends 330 of the heat conducting member 400 are, for example, steps that are formed in a sequence of upward steps from away from the first air outlet 104 to closer to the first air outlet 104.

[0107] In the embodiment of the present invention, a heat conducting member 400 is provided between the first blowing device 500 and the first air outlet 104. The heat conducting member 400 is arranged in sequence by a plurality of air guide plate groups, and the air outlet end 330 of the heat conducting member 400 can be formed into a stepped shape. There is an air flow channel between each two adjacent energy dissipation plates 232. Therefore, when the portable fan 10 is used, the first blowing device 500 blows air. Because the air outlet end 330 of the heat conducting member 400 is arranged in a stepped shape, when the wind passes through the heat conducting member 400, The air is blown out from different steps of the air outlet end 330 and directly guided to the first air outlet 104. As a result, the wind generated by the first blowing member can pass through the heat conducting member 400 to form multiple uniform air volumes or multiple preset air volumes and be blown out from the first air outlet 104 at different positions. At the same time, the loss of air volume can be reduced, so that wind of uniform wind force or wind of preset wind force can be blown out from the first air outlet 104 with a larger air volume, thereby improving the working efficiency of the portable fan 10 and enhancing the user experience.

[0108] Furthermore, as shown in Figures 19 and 20, the housing 100 includes, for example, an inner surface 140 and a side surface 150, which are adjacent to each other. A first air inlet 106 is provided on the inner surface 140, and a first air outlet 104 is provided on the side surface 150. The air outlet end 330 of the energy dissipating fin 232 is tilted toward the side surface 150. For example, the first air outlet 104 is provided on the inner surface 140, and the first blowing device 500 and the first air outlet 104 are offset, such that the first air outlet 104 is located above the first blowing device 500. Therefore, when the air outlet end 330 of the energy dissipating fin 232 is tilted toward the inner surface 140, air from the heat conducting member 400 is directed toward the first air outlet 104 by the heat conducting member 400, rather than away from the first air outlet 104, thereby preventing air loss. In this embodiment, the heat conducting member 400 is provided to guide the wind more evenly toward the first air outlet 104 while reducing the loss of air volume, thereby improving the working efficiency of the portable fan 10 and thus enhancing the user experience.

[0109] Optionally, as shown in Figures 19 and 20, in this embodiment, at least a portion of the airflow channel has a larger cross-sectional area near the air outlet end 330 than near the air inlet end 320. For example, airflow channels are formed between adjacent energy dissipation fins 232, so that when air blown from the first blowing device 500 passes through the heat conducting member 400, the air volume will pass through the airflow channel. The cross-sectional area of ​​the air flow channel near the air outlet end 330 is larger than the cross-sectional area near the air inlet end 320, that is, there is a certain angle between the two adjacent energy dissipation plates 232, and the angle gradually increases from the air inlet end 320 to the air outlet end 330. Therefore, when the wind is blown out from the air outlet end 330 of the heat conducting component 400, the air volume will spread. Because the step formed by the air outlet end 330 of the heat conducting component 400 corresponds to the first air outlet 104, the wind blown out from the air outlet end 330 can be blown out from multiple positions of the first air outlet 104, thereby improving the blowing effect of the portable fan 10 and improving the user experience.

[0110] Furthermore, in one implementation of this embodiment, at least a portion of the airflow channel has a greater width dimension near the air inlet end 320 than a width dimension near the air outlet end 330. Because there is a certain angle between two adjacent energy dissipation sheets 232, forming a radial arrangement, the air inlet end 320 is closer to the center of the radial circle, which narrows the airflow channel at the air inlet end 320. To avoid affecting the air intake of the thermal conductive element 400, the width dimension of the airflow channel at the air inlet end 320 is increased. For example, the width of the thermal conductive element 400 near the air inlet end 320 is larger, making it easier for air to enter, thereby ensuring the air intake of the thermal conductive element 400.

[0111] As shown in Figures 19 and 20, in one embodiment of the present embodiment, the lengths of the plurality of air guide vane groups are, for example, different. Specifically, among the plurality of air guide vane groups, the length of the air guide vane group close to the first air outlet 104 (i.e., the side surface 150) is, for example, less than the length of the air guide vane group away from the first air outlet 104 (i.e., the side surface 150). For example, the air guide vane group includes, for example, a plurality of energy distributing pieces 232, and the plurality of energy distributing pieces 232 included in each air guide vane group are, for example, energy distributing pieces 232 of the same length. Taking five groups of air guide vane groups as an example, the plurality of energy distributing pieces 232 in each group are, for example, energy distributing pieces 232 of the same length, but the lengths of the five groups of air guide vane groups are all different in length. Of course, the plurality of energy distributing pieces 232 in each group may also be energy distributing pieces 232 of different lengths, which is not limited here. Secondly, the plurality of air guide fin groups are arranged in descending order from long to short from away from the first air outlet 104 to close to the first air outlet 104, that is, the shortest air guide fin group in the thermal conductive element 400 is closest to the first air outlet 104. There are many ways to arrange the thermal conductive element 400, which are not limited here.

[0112] As shown in Figures 19 and 20, the distance between the air inlet end 320 and the air outlet end 330 of the thermal conductive element 400 is less than the length of the first air outlet 104, that is, the length of the thermal conductive element 400 is less than the length of the first air outlet 104. For example, the distance between the air inlet end 320 and the air outlet end 330 is equal to the entire length of the thermal conductive element 400, that is, the entire thermal conductive element 400 is located below the first air outlet 104. In other words, the air blown out from the air outlet end 330 of the thermal conductive element 400 can all be blown out from the first air outlet 104. Therefore, when the thermal conductive element 400 directs air toward the first air outlet 104, the air can be easily discharged from the first air outlet 104 and will not be retained within the device. Of course, the distance between the air inlet end 320 and the air outlet end 330 of the thermal conductive element 400 can also be equal to the length of the first air outlet 104, and this is not a limitation here. In this embodiment, the heat conducting member 400 is provided to evenly blow the air out of the device while avoiding air loss, thereby improving the working efficiency of the portable fan 10 and enhancing the user experience.

[0113] As shown in Figures 17 and 18, the housing 100, for example, encloses a wearing space 130. The portable fan 10, for example, further includes a refrigeration component 400. The refrigeration component 400 is located on a side of the heat conducting member 400 away from the wearing space 130. Specifically, the refrigeration component 400, for example, includes a thermostat 310 and a heat dissipation component 700. The thermostat 310 is thermally connected to the heat conducting member 400. The thermostat 310 is, for example, a semiconductor refrigeration component; the heat dissipation component 700 is, for example, a fin-type heat dissipation component. Specifically, the thermostat 310 is located on a side of the heat conducting member 400 away from the heat conducting member 400. The heat dissipation component 700 is located on a side of the heat conducting member 400 away from the heat conducting member 400 and is thermally connected to the thermostat 310.

[0114] As shown in Figures 18 and 21, for example, the thermostat 310 has a cold end and a hot end. The cold end is located on the side of the thermostat 310 close to the wearable space 130, that is, the cold end is close to the heat conducting member 400. The hot end is located on the side of the thermostat 310 away from the heat conducting member 400, that is, the hot end is close to the heat dissipation assembly 700. The housing 100 is also provided with a heat dissipation vent 105, which is in communication with the heat dissipation assembly 700. As a result, the cold energy generated by the cold end of the thermostat 310 can be transferred to the heat conducting member 400 and then blown out by the first blowing device 500. The air is guided by the heat conducting member 400 and blown out from the first air outlet 104 into the wearable space. As a result, the air temperature of the air blown to the user from the first air outlet 104 is lower, thereby improving the cooling effect of the portable fan 10 and enhancing the user experience. Secondly, the heat generated by the hot end of the temperature regulating element 310 can be conducted to the heat dissipation component 700, and then evacuated from the device through the heat dissipation port 105 by the heat dissipation component 700, thereby making the air volume and temperature in the device lower, thereby improving the cooling effect of the portable fan 10 and enhancing the user experience.

[0115] Furthermore, as shown in Figures 17 and 21, the housing 100 is further provided with a third air inlet 108, and a second air duct cavity communicating with the heat dissipation port 105 and the third air inlet 108. The heat dissipation component 700 is located in the second air duct cavity. The portable fan 10 further includes a second blowing device 600, for example. The second blowing device 600 is, for example, a centrifugal fan. The second blowing device 600 is provided in the second air duct cavity, and the heat dissipation component 700 is located between the second blowing device 600 and the heat dissipation port 105. In this embodiment, by arranging the second blowing device 600 close to the heat dissipation component 700, the heat at the heat dissipation component 700 can be quickly blown out from the heat dissipation port 105, thereby improving the heat dissipation efficiency of the heat dissipation component 700, thereby improving the cooling effect of the portable fan 10 and enhancing the user experience.

[0116] As shown in Figures 18 and 21 , the portable fan 10 further includes a partition bracket 200. The partition bracket 200 is located within the housing 100 and divides the housing 100 into a first air duct cavity and a second air duct cavity. A thermostat 310 is disposed on the partition bracket 200, with the cold end of the thermostat 310 located, for example, on the side of the partition bracket 200 that is closest to the first air duct cavity.

[0117] As shown in Figures 21 and 22, for example, the partition bracket 200 is provided with a receiving groove 610, and the thermostat 310 is embedded in the receiving groove 610. As a result, the partition bracket 200 can separate the interior of the shell 100 into two independent chambers, namely the first air duct chamber and the second air duct chamber. The cold end of the thermostat 310 is close to the first air duct chamber, that is, the cold energy generated by the cold end enters the first air duct chamber. Secondly, the hot end of the thermostat 310 is close to the second air duct chamber, that is, the heat generated by the hot end enters the second air duct chamber. In this embodiment, by providing the partition bracket 200, the interior of the shell 100 is divided into two independent chambers, thereby avoiding the mixing and interference of cold and heat. That is, when the portable fan 10 blows out cold air from the first air outlet 104, it will not be affected by the heat generated by the hot end of the thermostat 310, thereby improving the cooling effect of the portable fan 10 and improving the user experience of the portable fan 10.

[0118] Optionally, as shown in Figures 18 and 21, the first blowing device 500 and the second blowing device 600 are, for example, staggered relative to the partition bracket 200. For example, the first blowing device 500 and the second blowing device 600 are, for example, respectively disposed on opposite sides of the partition bracket 200. By staggering the first blowing device 500 and the second blowing device 600, the volume of the same end of the partition bracket 200 can be reduced, thereby reducing the volume of the entire device, thereby improving the aesthetics of the device.

[0119] As shown in Figures 17 and 18, the housing 100 includes, for example, a first housing 110 and a second housing 120, which are connected to form an accommodating space. The partition bracket 200, the temperature regulating member 310, the first blowing device 500, the heat conducting member 400, the second blowing device 600, and the heat dissipation assembly 700 are, for example, all disposed within the accommodating space.

[0120] Alternatively, as shown in Figures 17 and 18, in this embodiment, the inner surface 140 and the side surface 150 are, for example, both provided on the first housing 110, that is, the first air outlet 104 and the first air inlet 106 are provided on the first housing 110, thereby forming a first air duct cavity enclosed by the first housing 110 and the partition bracket 200. The heat dissipation vent 105 and the third air inlet 108 are, for example, provided on the second housing 120, thereby forming a second air duct cavity enclosed by the second housing 120 and the partition bracket 200.

[0121] As shown in Figures 22 and 23, in one embodiment of this embodiment, a first air shield 113 is provided on the first housing 110. The heat conducting member 400 is located between the first air shield 113 and the first blowing device 500. An air duct is formed between the first air shield 113 and the air outlet 330, and the air duct communicates with the air outlet 330 and the first air outlet 104.

[0122] As shown in Figures 22 and 23, for example, the air duct has an inlet end and an outlet end. The inlet end is connected to the air outlet end 330 of the heat conducting member 400, and the outlet end is connected to the first air outlet 104. Thus, when the wind is blown out from the air outlet end 330 through the heat conducting member 400, it will be directly guided to the first air outlet 104 by the air duct, so that the wind is quickly blown out from the first air outlet 104 and the loss of air volume is avoided, thereby improving the working efficiency of the portable fan 10 and improving the user experience. Of course, in other embodiments, the first wind shield 113 can also be arranged on the partition bracket 200, or partially arranged on the first shell 110 and partially arranged on the partition bracket 200. When the first shell 110 and the partition bracket 200 are buckled together, they form a complete first wind shield 113.

[0123] Optionally, as shown in Figures 22 and 23, in another embodiment of the present embodiment, a first wind shield 113 and a second wind shield 114 are provided on the first shell 110, for example. The first wind shield 113 and the second wind shield 114 are adjacent and spaced apart. The heat conducting member 400 is located between the first wind shield 113 and the first blowing device 500. The second wind shield 114 is located between the first wind shield 113 and the heat conducting member 400, and a first air duct 1131 is formed between the first wind shield 113 and the second wind shield 114. A second air duct 1132 is formed between the second wind shield 114 and the air outlet end 330. The first air duct 1131 and the second air duct 1132 are respectively connected to the air outlet end 330 and the first air outlet 104. One or more wind shields may be provided on the first shell 110, and there is no limitation here. Similarly, the first wind shield 113 and the second wind shield 114 can also be set on the partition bracket 200, or partially set on the first shell 110 and partially set on the partition bracket 200. When the first shell 110 and the partition bracket 200 are buckled together, they together form a complete first wind shield 113 and second wind shield 114.

[0124] Furthermore, as shown in Figures 22 and 23, an air duct can also be formed between the heat conducting member 400 and the first blowing device 500. The air duct is connected to the air inlet end 320 and the air outlet of the first blowing device 500. Therefore, when the first blowing device 500 blows air, the blown air is directly guided to the air inlet end 320 by the air duct, thereby allowing the air to be conducted to the heat conducting member 400 more quickly, thereby improving the working efficiency of the portable fan 10 and enhancing the user experience. The portable fan 10 of this embodiment also includes commonly used components such as a power supply, which are not described in detail here.

[0125] The embodiment of the present invention sets a heat conducting member 400 between the first blowing device 500 and the first air outlet 104. The heat conducting member 400 is arranged in sequence by a plurality of air guide plate groups, and the air outlet end 330 of the heat conducting member 400 can be formed into a stepped shape. There is an air flow channel between each two adjacent energy dissipation plates 232. Therefore, when the portable fan 10 is used, the first blowing device 500 blows air. Because the air outlet end 330 of the heat conducting member 400 is arranged in a stepped shape, when the wind passes through the heat conducting member 400, it can be blown out from different steps of the air outlet end 330. This arrangement makes the outlet surface of the outlet end 330 opposite to the first air outlet 104, so the wind blown out from different steps will be directly directed to the first air outlet 104, thereby allowing the wind generated by the first blowing member to pass through the temperature conducting member 400 to form multiple uniform air volumes or multiple preset air volumes and blow out from the first air outlet 104 at different positions, while reducing the loss of air volume, so that wind of uniform wind force or wind of preset wind force and a larger air volume can be blown out from the first air outlet 104, thereby improving the working efficiency of the portable fan 10 and enhancing the user experience. Secondly, by providing the temperature regulating member 310, the heat dissipation assembly 700 and the second blowing device 600, the temperature of the wind blown out from the first air outlet 104 can be lowered, thereby improving the cooling effect of the portable fan 10 and enhancing the user experience.

[0126] 24 to 26 , the present invention provides a wearable hair dryer, including a housing 100 , wherein a cavity is formed in the housing 100 ; a partition bracket 200 , a temperature regulating assembly 300 and a first hair dryer 500 are provided in the cavity.

[0127] The partition bracket 200 separates the cavity into the second accommodating chamber 103 and the first accommodating chamber 102. The first blowing device 500 cooperates to generate two streams of air within the cavity, blowing them toward the second accommodating chamber 103 and the first accommodating chamber 102 respectively. The thermostat assembly 300 includes a thermostat 310, a thermal conductive element 400, and a heat sink 701. The thermostat 310 is used to generate cooling through the thermal conductive element 400, and the heat sink 701 is used to conduct heat generated by the thermostat 310.

[0128] The thermostat 310 is fixed to the partition bracket 200. The thermal conductive element 400 is thermally connected to the cold end of the thermostat 310 and is located within the second accommodating chamber 103, allowing air within the second accommodating chamber 103 to pass through the thermal conductive element 400. The heat sink 701 is thermally connected to the hot end of the thermostat 310 and is located within the first accommodating chamber 102, allowing air within the first accommodating chamber 102 to pass through the heat sink 701.

[0129] The first blowing device 500 is provided with a first fan blade 510 and a second fan blade 520. The first fan blade 510 is arranged corresponding to the air flow inlet of the second accommodating chamber 103, and the air flow generated by the first fan blade 510 blows toward the second accommodating chamber 103; the second fan blade 520 is arranged corresponding to the air flow inlet of the first accommodating chamber 102, and the air flow generated by the second fan blade 520 blows toward the first accommodating chamber 102.

[0130] Similarly, the first fan blade 510 can also be set corresponding to the air flow inlet of the first accommodating chamber 102, and the air flow generated by the first fan blade 510 blows toward the first accommodating chamber 102; the second fan blade 520 is set corresponding to the air flow inlet of the second accommodating chamber 103, and the air flow generated by the second fan blade 520 blows toward the second accommodating chamber 103.

[0131] The cavity is divided into a second accommodating chamber 103 and a first accommodating chamber 102, on which the heat conducting component 400 and the heat dissipating component 701 are installed respectively. The first fan blade 510 and the second fan blade 520 on the first blowing device 500 respectively generate two airflows that blow towards two spaces. Heat dissipation and cooling are achieved simultaneously through one first blowing device 500. There is no need to set up two first blowing devices 500, which saves equipment costs and installation space.

[0132] Referring to Figures 25, 26, 28, and 29, in the present invention, the first blades 510 are arranged corresponding to the airflow inlet of the second accommodating chamber 103, and the second blades 520 are arranged corresponding to the airflow inlet of the first accommodating chamber 102. The airflow generated by the first blades 510 blows toward the temperature conducting member 400, and the airflow generated by the second blades 520 blows toward the heat dissipating member 701. The first blades 510 include a plurality of first blades 411, and the second blades 520 include a plurality of second blades 421. The first blades 411 and the second blades 421 are arranged along the circumferential direction of the fan.

[0133] The radial width of the first blade 411 is smaller than the radial width of the second blade 421, so that the wind force from the first blade 510 toward the heat transfer element 400 is not too strong, and the wind blowing toward the heat transfer element 400 is not too strong, so that the wind can fully contact the heat transfer element 400 to conduct cooling, ensuring that the wind blowing out after the heat transfer element 400 can effectively cool the air. The wind from the second blade 520 toward the heat transfer element 701 is stronger, ensuring that the heat on the heat transfer element 701 is removed in a timely manner, thereby avoiding affecting the cooling effect of the thermostat 310.

[0134] By adjusting the blade sizes of the first fan blade 510 and the second fan blade 520, the required air volume size / ratio of the corresponding temperature conducting component 400 and the heat dissipating component 701 can be adjusted as needed, thereby achieving the effect of adjusting the required air volume of both at the same time. Compared with the existing method of using two fans for heat dissipation and cooling respectively, the control circuits of the two fans need to be adjusted separately when adjusting the air volume, which simplifies the control cost of air volume adjustment.

[0135] As another embodiment, in order to make the amount of air blown out by the first fan blade 510 and the second fan blade 520 different, the axial height dimension of the first blade 411 can also be set to be smaller than the axial height dimension of the second blade 421, or the axial height and radial width dimensions of the first blade 411 can be simultaneously smaller than the axial height and radial width dimensions of the second blade 421, so that the areas of wind formed by the first fan blade 510 and the second fan blade 520 are different, thereby achieving different air volumes.

[0136] The first blowing device 500 also includes an isolation plate 530, which can separate the two groups of fan blades of the first blowing device 500. The isolation plate 530 is arranged between the first fan blade 510 and the second fan blade 520. When the first blowing device 500 rotates, the isolation plate 530 acts as a barrier, so that the two airflows generated by the first blowing device 500 do not affect each other.

[0137] The isolation plate 530 forms the first blade 510 and the second blade 520 on both sides of the separation bracket 200 , respectively, so that the first blade 510 corresponds to the second accommodating cavity 103 and the second blade 520 corresponds to the first accommodating cavity 102 .

[0138] Furthermore, the first blades 411 and the second blades 421 are disposed on the surfaces of both sides of the isolation plate 530. The isolation plate 530 is annular, and the first blades 411 and the second blades 421 are distributed along the circumference of the isolation plate 530. The radial inner edge is located near the center of the first blowing device 500, and the radial outer edge is located near the outer edge of the first blowing device 500. The distance between the radial outer edge of the first blade 411 and the radial outer edge of the isolation plate 530 is greater than the distance between the radial outer edge of the second blade 421 and the radial outer edge of the isolation plate 530, and the radial outer edge of the second blade 421 is flush with the radial outer edge of the isolation plate 530. Furthermore, the radial inner edges of the first blade 411 and the second blade 421 are each flush with the radial inner edge of the isolation plate 530, resulting in a smaller area size of the first blade 411 than that of the second blade 421.

[0139] By making the first blade 411 and the second blade 421 different in size, two different air volumes are generated. Importantly, less air is directed toward the second accommodating chamber 103, ensuring that all air is cooled, while more air is directed toward the first accommodating chamber 102, ensuring that heat from the heat sink 701 is dissipated promptly.

[0140] The radial outer edge of the first blade 411 and the radial outer edge of the second blade 421 are staggered in the circumferential direction, so that the blade gap between the first blade 510 and the second blade 520 is staggered, reducing mutual interference and vibration between the blades.

[0141] Furthermore, a mounting housing 431 is provided in the middle of the annular isolation plate 530. Housing 431 houses a drive assembly for driving the first blowing device 500. This drive assembly is used to drive the fan to generate airflow. Mounting housing 431 is located at the center of isolation plate 530. The sidewalls of mounting housing 431 are connected to isolation plate 530 via spokes. The drive assembly drives mounting housing 431, rotating isolation plate 530 and, in turn, rotating the fan blades mounted on isolation plate 530, generating airflow.

[0142] The thickness of the first blade 411 on the side of the partition plate 42 closest to the mounting housing 431 is thinner than the thickness of the first blade on the side away from the mounting housing 431. The side away from the mounting housing 431 is the outlet side. The thicker blade on the outlet side provides stronger fanning, making the fan more stable and reliable at high speeds, allowing the wind to be more fully pushed and generating a stronger airflow. Similarly, the thickness of the second blade 421 on the side closest to the mounting housing 431 is also thinner than the thickness of the second blade 421 on the side away from the mounting housing 431, achieving the same airflow effect as the first blade 411.

[0143] Furthermore, the radial inner edge of first blade 411 is an arc-shaped surface, while the radial outer edge is a flat surface. Airflow exits from the radial outer edge, while the radial inner edge enters. The arc-shaped radial inner edge facilitates smooth airflow into the fan blade and out through the air outlet. Similarly, the radial inner edge of second blade 421 is an arc-shaped surface, while the radial outer edge is a flat surface, achieving the same airflow effect as second blade 421.

[0144] Continuing with Figures 24 to 26 , the housing 100 includes a second housing 110 and a second housing 120, which enclose a cavity. A first air inlet 106 is provided on each of the second housings 110 and 120. Both sides of the first blowing device 500 correspond to the first air inlets 106 on the second housings 110 and 120, respectively. The first air inlets 106 connect the cavity to the outside world, allowing the first blowing device 500 to take in air and generate airflow.

[0145] Furthermore, the first air inlet 106 on the second shell 110 corresponds to the first air inlet 106 on the second shell 120, and the two sides of the first blowing device 500 correspond to the positions of the first air inlets 106 of the second shell 110 and the second shell 120 respectively, so that the first fan blade 510 and the second fan blade 520 can take in air from different first air inlets 106, thereby improving the ventilation effect.

[0146] In order to facilitate a more stable installation of the first blowing device 500 in the cavity, a mounting volute 115 is provided on the side of the second housing 110 facing the cavity, and the first blowing device 500 is disposed within the mounting volute 115. In addition, an opening is provided on the side of the mounting volute 115 near the partition bracket 200, so that the space within the mounting volute 115 can communicate with the second accommodating chamber 103 and the first accommodating chamber 102, and the airflow generated by the first blowing device 500 can flow to the second accommodating chamber 103 and the first accommodating chamber 102.

[0147] A guide plate 112 is also provided on the mounting volute 115. The guide plate 112 is provided at the opening of the mounting volute 115, that is, the guide plate 112 is provided on a side of the mounting volute 115 close to the second accommodating chamber 103 and the first accommodating chamber 102. The guide plates 112 are provided in correspondence with the second accommodating chamber 103 and the first accommodating chamber 102. The guide plates 112 guide the airflow generated by the first blowing device 500 into the second accommodating chamber 103 and the first accommodating chamber 102, thereby ensuring a more concentrated flow direction of the airflow and reducing air loss and waste.

[0148] Preferably, after the first blowing device 500 generates an airflow through the first air inlet 106, it needs to be blown out from the first air outlet 104. A first air outlet 104 is provided on the shell 100. The airflow generated by the first fan blade 510 in the first blowing device 500 will pass through the heat conducting member 400 and then be blown out from the first air outlet 104, thereby achieving a cooling effect on the human body. The first air outlet 104 is provided on the second shell 110, connecting the second accommodating chamber 103 and the external space. The heat conducting member 400 is in the second accommodating chamber 103, so that the airflow after passing through the heat conducting member 400 can be discharged from the second accommodating chamber 103. Preferably, the first air outlet 104 is provided on a side of the second shell 110 that is coplanar with the second shell 120, so as to avoid the first air outlet 104 being blocked by the side worn by the human body in the wearable blowing device. As another feasible method, the first air outlet 104 can be set at the connection between the second shell 110 and the second shell 120, or on the second shell 120, and similarly set on the side of the two coplanar, to avoid the first air outlet 104 being blocked when worn by the human body.

[0149] The first air outlet 104 can discharge the airflow passing through the second accommodating chamber 103 and blow it toward the human body. The second accommodating chamber 103 is separated from the first accommodating chamber 102 by a partition bracket 200 and other components. Therefore, it is necessary to provide a heat dissipation vent 105 for exhaust on the second shell 120. The heat dissipation vent 105 is provided on the side of the second shell 120 away from the second shell 110, and the airflow after the second fan blade 520 passes through the heat dissipation element 701 is discharged from the heat dissipation vent 105 on the second shell 120. The second shell 110 faces the human body, and the heat dissipation vent 105 is provided on the side of the second shell 120 away from the second shell 110 to prevent the hot airflow from blowing toward the human body.

[0150] Please refer to Figures 26 and 27. The partition bracket 200 is arranged at the connection between the second shell 110 and the second shell 120. The second shell 110 and the partition bracket 200 enclose the second accommodating chamber 103, and the second shell 120 and the partition bracket 200 enclose the first accommodating chamber 102. The second accommodating chamber 103 is isolated from the first accommodating chamber 102 by the partition bracket 200 in cooperation with the temperature control component 300. The setting of the partition bracket 200 can make the structure of the temperature control component 300 more stable and strong, and avoid interference caused by internal airflow.

[0151] The partition bracket 200 includes a partition 210 and two side panels 220. The partition 210 divides the cavity into the second accommodating chamber 103 and the first accommodating chamber 102. The side panels 220 are perpendicular to the partition 210, located on both long sides of the partition 210, and extend along the length of the partition 210. The temperature control assembly 300 mounted on the partition bracket 200 is wrapped around the top and bottom to facilitate installation and fixation.

[0152] Preferably, a receiving groove 610 is provided on the partition 210, and the thermostat 310 is disposed in the receiving groove 610. The cold end of the thermostat 310 is exposed within the second accommodating chamber 103, and the hot end of the thermostat 310 is exposed within the first accommodating chamber 102. A thermal conductor 400 is secured to the partition 210 and connected to the cold end of the thermostat 310 via a heat transfer medium. A heat sink 701 is also secured to the partition 210 and connected to the hot end of the thermostat 310 via a heat transfer medium. Both the thermal conductor 400 and the heat sink 701 are mounted on a partition bracket 200. The partition bracket 200 helps optimize the airflow path, ensuring that airflow within the second accommodating chamber 103 and the first accommodating chamber 102 transfers temperature through the thermal conductor 400 and the heat sink 701.

[0153] Specifically, an air guide 230 is further provided on the partition 210. The air guide 230 is arranged on the side facing the second accommodating chamber 103 and is used to guide the wind in the second accommodating chamber 103 to blow toward the first air outlet 104, thereby reducing the waste of airflow during the flow process and improving the utilization rate of the airflow. The air guide 230 is provided with a first guide end 231 and a second guide end 233. The first cold guide end 231 is arranged on the side of the partition bracket 200 close to the thermal conductive member 400 and away from the first air outlet 104; the second guide end 233 is arranged on the side of the partition bracket 200 close to the first air outlet 104 and away from the thermal conductive member 400. After passing through the thermal conductive member 400, the airflow is guided to the second guide end 233 through the first cold guide end 231 of the air guide 230 and is discharged from the first air outlet 104 after approaching the first air outlet 104. By arranging the orientation of the air guide 230, the flow path of the airflow in the second accommodating chamber 103 can be optimized, ensuring that the airflow flows along the designed path to the first air outlet 104. In addition, in the embodiment of the present invention, two air guides 230 are provided, which guide the flow direction of the cooling airflow in two paths.

[0154] Please refer again to Figures 24 to 26. The wearable hair dryer of the present invention is used to be worn on the user's neck to blow air to the human body. The housing 100 includes a first wearing arm 1011 and a second wearing arm 1012. The first wearing arm 1011 and the second wearing arm 1012 are connected by a connecting section 14 and enclose a wearing space 130. The user wears the device around the neck through the wearing space 130. The connecting section 14 is a flexible member that can adjust the size of the wearing space 130 formed between the first wearing arm 1011 and the second wearing arm 1012 by deformation. Of course, in other embodiments, the housing 100 may also not include the connecting section 14, and the first wearing arm 1011 and the second wearing arm 1012 may jointly enclose the wearing space 130.

[0155] The first wearing arm 1011 and the second wearing arm 1012 are both provided with a second shell 110 and a second shell 120, and the two sets of second shells 110 and second shells 120 enclose the first wearing arm 1011 and the second wearing arm 1012. The second shells 110 on the first wearing arm 1011 and the second wearing arm 1012 are both provided on the side close to the wearing space 130, and the second shells 120 are provided on the side away from the wearing space 130. The heat dissipation vents 105 on the second shells 120 are away from the wearing space 130 to prevent hot air from blowing towards the human body.

[0156] A battery assembly is provided inside both the first wearing arm 1011 and the second wearing arm 1012, located at the end away from the connector. Furthermore, a mounting vortex housing 115 for the first blowing device 500 is provided in the second housing 110 at one end near the connecting section 14, so that the airflow generated by the first blowing device 500 is directed toward the side away from the connecting section 14, thereby preventing the airflow in the two wearing arms from crossing through the connecting section 14.

[0157] As shown in Figure 31, the present invention provides a thermal conductor 2, which can be a radiator or a heat dissipation or cooling device installed on other equipment that requires temperature transfer. The thermal conductor 2 transfers temperature through fins 3. The thermal conductor 2 in this embodiment of the present invention includes at least two fins 3. Each fin 3 is provided with at least one through-slot 4, forming an airflow channel between two adjacent fins 3. At least one spoiler 6 is provided in the airflow channel. The spoiler 6 is provided in the airflow channel to continuously disrupt the formation of the airflow boundary layer.

[0158] The through slots 4 are through-hole structures that run through both sides of the fins 3. Their shapes can be circular, square, triangular, etc., and the present invention does not impose any specific restrictions. In a specific implementation, the through slots 4 can be square through-holes. The provision of the through slots 4 allows gas to flow between two adjacent airflow channels. Multiple through slots 4 can be distributed along the length of a fin 3.

[0159] Among them, the through slots 4 on the same fin 3 include multiple ones, and their arrangement direction is arranged along the length direction (X direction). The spoiler 6 on each fin 3 can be set on the inner side of the through slot 4, and the position and number of the through slots 4 on each fin 3 are the same. The spoiler 6 is fixedly mounted on the fin 3. In this embodiment, the temperature conductor 2 is used in conjunction with a power unit that can generate wind power, and the heat or cold on the fin 3 is taken away by the wind power. In this process, the wind power forms an airflow channel between the fins 3. The spoiler 6 in the airflow channel will change the direction of part of the airflow, disrupt the airflow in the channel, continuously destroy the formation of the airflow boundary layer, and enhance the heat exchange efficiency of the airflow. In a specific implementation, the number of through slots 4 on each fin 3 can be different, and the size is not specifically limited. The spoiler 6 is fixedly connected to the fin 3. Since the number of through slots 4 on different fins 3 is different, the heat dissipation performance of each fin 3 is different, and the air flow channel pressure between the fins 3 is different. The wind force between adjacent air flow channels can interact through the through slots 4, thereby disrupting the air flow in the channel, continuously destroying the formation of the air flow boundary layer, and enhancing the heat exchange efficiency of the air flow. In this embodiment, the through slots 4 and the spoiler 6 together achieve the effect of destroying the formation of the air flow boundary. In another specific implementation, the position of the through slots 4 on each fin 3 is different, and the spoiler 6 is fixedly connected to the fin 3. Similarly, when the position of the through slots 4 on each fin 3 is different, the air flow pressure in a section of the air flow channel is different from that of the adjacent air flow channel. The two adjacent air flow channels usually exchange gas to destroy the formation of the air flow boundary and enhance the heat exchange efficiency of the air flow.

[0160] Wherein, the number of spoilers 6 can be multiple, and they can be arranged on at least one side of the fin 3 and / or on the substrate, and their arrangement direction is arranged along the length direction (X direction). Wherein, the spoiler 6 is arranged on the fin 3, which will change part of the airflow in the airflow channel to flow along the extension direction of the spoiler 6. The spoiler 6 can be arranged on the same side of the same fin 3, or on two sides. Wherein, the substrate is a component at the bottom of the heat conductor 2 for supporting the fin 3. In a specific implementation, when multiple spoilers 6 are arranged on the same side of the fin 3, the intervals between them are not fixed, and the multiple spoilers 6 are not on the same straight line. In another specific implementation, when multiple spoilers 6 are arranged on two sides of the fin 3, the spoilers 6 on the two sides can be symmetrically arranged or asymmetrically arranged, and the embodiment of the utility model does not make specific restrictions. In another specific implementation, the angle between the spoiler 6 and the fins 3 is 20°-30°. When the spacing between the fins 3 is constant, as the angle of the spoiler 6 increases, the amount of air flowing between the fins 3 decreases, while the amount of air flowing along the spoiler 6 increases, resulting in enhanced heat exchange. However, at the same time, the area affected by the thermal wake behind the spoiler 6 also changes, resulting in weakened heat exchange. When the angle between the spoiler 6 and the fins 3 is 20°-30°, the thermal wake can be effectively disrupted, reducing its impact on heat exchange.

[0161] Wherein, the spoilers 6 in an airflow channel can be the same or different in position and number, and the setting directions can also be the same or different. Wherein, in a specific implementation, the extension directions of the spoilers 6 in the same airflow channel can be sequentially ordered, such as when the extension direction of the spoilers 6 is along the X direction, multiple spoilers 6 are arranged in sequence along the positive X direction and the reverse X direction. In another specific implementation, the extension direction of some spoilers 6 distributed along the direction of the fin 3 in an airflow channel is opposite to the direction of the remaining spoilers 6; wherein the spoilers 6 can be divided into two groups, one group of spoilers 6 extending in the positive X direction, and the other group of spoilers 6 extending in the reverse X direction, and the two groups of spoilers 6 are respectively set at both ends of the fin 3 or the substrate. In another specific implementation, the spoilers 6 can be set on the fin 3 or the substrate, and the setting directions of the spoilers 6 in the same airflow channel can be disordered, for example, first set a spoiler 6 extending in the positive X direction, then set two spoilers 6 extending in the reverse X direction, and so on.

[0162] As shown in Figures 31 and 32, the spoiler 6 is a sheet-like structure that forms a preset angle with the side surface. The spoiler 6 can be a sheet-like structure such as a wave, rectangle, triangle, or diamond. It needs to meet the airflow to achieve the diversion effect, and the material of the spoiler 6 is not required, as long as it can maintain a stable shape. One side of the sheet-like structure is set on the side of the fin 3, wherein the spoiler 6 of the sheet-like structure can be set near the through groove 4 or set separately from the through groove 4. As shown in Figures 33 and 34, in a specific implementation, the spoiler 6 is a rectangular structure, and one side of the spoiler 6 is set at the inner edge of the through groove 4, forming a window structure with the through groove 4. The spoiler 6 is located within the projection range of the through groove 4 and forms a window structure with the through groove 4. In other words, the spoiler 6 is torn from the body of the fin 3, making it more convenient to process the spoiler 6 on the fin 3. Since the pressure of the airflow in the airflow channel located at the spoiler 6 is uneven with that of the adjacent airflow channel, and the through groove 4 is located at the spoiler 6, the airflow in the airflow channel flows to the adjacent airflow channel, thereby destroying the formation of the airflow boundary layer.

[0163] As shown in Figures 31 and 32, in one embodiment of the present invention, the shape of the spoiler 6 can also be an irregular shape. In this embodiment, the spoiler 6 includes a connecting piece 602 and a spoiler 601 that is not in the same plane as the connecting piece 602; one end of the connecting piece 602 is connected to the spoiler 601; the other end of the connecting piece 602 is fixedly connected to the side of the fin 3 so that; the connecting piece 602 is inclined relative to the side of the fin 3, and the spoiler 601 is parallel to the side of the fin 3 or inclined outward relative to the side of the fin 3.

[0164] Among them, the connecting piece 602 and the spoiler 601 are both rectangular, and the first side of the spoiler 601 is connected to the second side of the connecting piece 602, so that the angle between the connecting piece 602 and the spoiler 601 is an obtuse angle. In addition, the arrangement direction between the connecting piece 602 and the spoiler 601 is perpendicular to the length direction of the airflow channel, that is, the connecting piece 602 and the spoiler 601 are arranged along the width direction of the fin 3. In one implementation, one end of the connecting piece 602 is fixedly connected to the side of the fin 3, and the angle between the connecting piece 602 and the fin 3 can be 20°-30°, and the spoiler 601 is parallel to the side of the fin 3. After the airflow meets the spoiler 6, part of the airflow flows along the shape of the spoiler 6, thereby disrupting the airflow in the channel, continuously destroying the formation of the airflow boundary layer, and enhancing the heat exchange efficiency of the airflow. In another implementation, one end of the connecting piece 602 is fixedly connected to the side of the fin 3. At this time, a certain inclination angle or direct verticality is provided between the spoiler 601 and the side of the fin 3, which can also achieve the effect of destroying the formation of the airflow boundary layer.

[0165] As shown in Figures 35 to 37, the present invention also provides a neck-hanging air conditioner, including the above-mentioned thermoconductor. The neck-hanging air conditioner also includes a first shell 110, a second shell 120, and a partition bracket 200. The partition bracket 200 is located between the second shell 120 and the first shell 110. The partition bracket 200 is provided with a mounting groove for accommodating the thermostat 310, so that the heating end of the thermostat 310 faces the first accommodating cavity formed by the partition bracket 200 and the second shell 120, and the cooling end of the thermostat 310 faces the second accommodating cavity formed by the partition bracket 200 and the first shell 110; the first shell 110 is provided with a first air outlet 104 and a first air inlet 106, and the second shell 120 is provided with a heat dissipation port 105 and a second air inlet 107.

[0166] Among them, the thermoconductor 2 is thermally connected to the heating end and the cooling end of the thermostat 310, and the external air is guided to flow in the cold / hot air outlet and the cold / hot air inlet through the centrifugal fan. The thermostat 310 is arranged in the installation groove on the partition bracket 200, so that the cooling end and the heating end of the thermostat 310 are respectively located on the two sides of the partition bracket 200, and the structure of the partition bracket 200 matches the first shell 110 and the second shell 120, thereby separating the first accommodating cavity from the second accommodating cavity. Therefore, the heat dissipation duct and the cooling duct formed on the two sides of the centrifugal fan and the thermostat 310 are completely isolated, thereby improving the efficiency of cooling and heat dissipation.

[0167] The second shell 120 and the first shell 110 are both non-enclosed annular structures, and the structural shape of the temperature conductor 2 matches the shapes of the first shell 110 and the second shell 120. The first shell 110 is set on the side close to the human skin, and the second shell 120 is set on the side away from the human skin. The first air outlet 104 and the first air inlet 106 are set on the first shell 110. In this embodiment, the first air outlet 104 is set at the upper part of the first shell 110, so that the cold air blows towards the head of the human body, while the first air inlet 106 is set in the middle of the first shell 110. During the inhalation process, the outside air can help reduce the temperature of the neck. The heat dissipation vent 105 and the second air inlet 107 are set on the second shell 120, so that the hot air blown out is away from the human skin.

[0168] Please refer to Figures 38 to 46. A portable fan 10 provided in one embodiment of the present invention is used to be worn around the neck of a user to blow air toward the neck or head of the user to create a cooling effect for the user.

[0169] The portable fan 10 includes a wearing bracket 12, a temperature control component 300 and a fan component 16. The wearing bracket 12 forms a wearing space 130. The portable fan 10 can be worn on the neck through the wearing space 130. The temperature control component 300 and the fan component 16 are respectively arranged inside the wearing bracket 12. The temperature control component 300 can cool, and the fan component 16 drives the outside air into the wearing bracket 12 and flows through the temperature control component 300. After the temperature control component 300 cools the passing air, the fan component 16 drives the airflow to blow toward the user, forming the effect of blowing cold air, reducing the influence of the external ambient temperature on the cooling effect of the portable fan 10, and improving the cooling effect of the portable fan 10.

[0170] The wearing bracket 12 is preferably made of a material with a certain degree of flexibility, such as silicone, to ensure wearing comfort. At the same time, the wearing bracket 12 can produce a certain degree of deformation to adjust the size of the wearing space 130, so that the portable fan 10 can better adapt to different users.

[0171] The wearing bracket 12 includes a neck hanging portion 20 and handle portions 23 connected to both ends of the neck hanging portion 20. The two handle portions 23 and the neck hanging portion 20 together enclose a wearing space 130. The temperature control component 300 is located in the neck hanging portion 20, and the fan component 16 is located in the neck hanging portion 20 and / or the handle portions 23. During use, the user can grasp the handle portions 23 with both hands and then wear the portable fan 10 around the neck. After the portable fan 10 is worn around the neck, the neck hanging portion 20 is located on the back of the neck, and the two handle portions 23 are located on opposite sides of the neck.

[0172] It is understandable that the neck portion 20 and the two handle portions 23 can be integrally formed or assembled separately.

[0173] The temperature regulating component 300 includes a temperature regulating component 310 and a temperature conducting component 400 and a heat dissipation component 700 respectively connected to opposite sides of the temperature regulating component 310. Specifically, the temperature conducting component 400 is located on the side of the temperature regulating component 310 close to the wearing space 130, and the heat dissipation component 700 is located on the side of the temperature regulating component 310 away from the wearing space 130. When the temperature regulating component 310 works, the side close to the wearing space 130 serves as a cooling end and generates cold energy, and the side away from the wearing space 130 serves as a heat generating end and generates heat. The cooling capacity generated by the heat dissipation module 10 can be transferred to the heat conducting component 400, so that the temperature of the heat conducting component 400 is reduced, and the heat generated is transferred to the heat dissipation component 700, so that the overall temperature of the temperature regulating component 310 is reduced, while the overall temperature of the heat dissipation component 700 is increased. The contact area between the heat dissipation component 700 and the air is large, and the heat dissipation effect is better. The temperature regulating component 310 uses the heat dissipation component 700 to assist in heat dissipation, and promptly transfers the heat generated on the side of the temperature regulating component 310 away from the wearing space 130 to ensure the heat dissipation effect of the temperature regulating component 310.

[0174] In the present application, the temperature regulating element 310 is a semiconductor refrigeration sheet, which is in the shape of a sheet as a whole. The temperature conducting element 400 and the heat dissipating assembly 700 are respectively attached and fixed on opposite sides of the semiconductor refrigeration sheet.

[0175] The wearing bracket 12 is provided with a blowing duct 30, a blowing duct inlet 32 ​​and a blowing duct outlet 34 connected to the blowing duct 30, a heat dissipation duct 36, and a heat dissipation duct inlet 38 and a heat dissipation duct outlet 40 connected to the heat dissipation duct 36. The temperature conducting component 400 is located in the blowing duct 30, the heat dissipation component 700 is located in the heat dissipation duct 36, and the fan component 16 includes a blowing fan located in the blowing duct 30 and a heat dissipation fan 47 located in the heat dissipation duct 36. When the blower fan is working, it can draw outside air into the blowing duct 30 through the blowing duct inlet 32, and drive the air flow in the blowing duct 30 to flow toward the blowing duct outlet 34. During the flow of the air flow in the blowing duct 30, the air flow will pass through the temperature conducting member 400 and exchange heat with the temperature conducting member 400. Since the temperature of the temperature conducting member 400 is relatively low, the temperature of the air flow is reduced after the heat exchange with the temperature conducting member 400. The cooled air flow is then blown toward the user from the blowing duct outlet 34, forming the effect of blowing cold air, reducing the influence of the external ambient temperature on the cooling effect of the portable fan 10, and improving the cooling effect of the portable fan 10 on the user; when the heat dissipation fan 47 is working, it can draw outside air through the heat dissipation duct inlet 3 8 is sucked into the heat dissipation duct 36 and drives the air flow in the heat dissipation duct 36 toward the heat dissipation duct outlet 40. During the flow of the air flow in the heat dissipation duct 36, the air flow passes through the heat dissipation component 700 and exchanges heat with the heat dissipation component 700. Since the temperature of the heat dissipation component 700 is relatively high, the air flow can take away the heat on the heat dissipation component 700 when passing through the heat dissipation component 700, and then be discharged from the heat dissipation duct outlet 40. After the heat on the heat dissipation component 700 is taken away by the air flow, the temperature is reduced, so that the heat generated on the side of the temperature regulating component 310 away from the wearing space 130 can be quickly transferred to the heat dissipation component 700, ensuring the cooling effect of the temperature regulating component 310, so as to ensure the effect of the temperature conducting component 400 in cooling the passing air flow.

[0176] The specific positions of the blowing duct inlet 32 ​​and the blowing duct outlet 34 are not limited, and the two can be located on the same side of the wearing bracket 12, or on different sides of the wearing bracket 12. For example, the blowing duct inlet 32 ​​can be set on the side of the wearing bracket 12 close to or away from the wearing space 130, or it can be set on the side of the wearing bracket 12 in its height direction. The blowing duct outlet 34 can be set on the side of the wearing bracket 12 close to the wearing bracket 12, or it can be set on the side of the wearing bracket 12 in its height direction, as long as it can blow towards the user.

[0177] In this application, the height direction of the wearing bracket 12 refers to the height direction of the wearing bracket 12 when it is worn on the human body. Specifically, the wearing bracket 12 is an open ring structure, and the height direction of the wearing bracket 12 is also the axial direction of the wearing space 130.

[0178] Preferably, the heat dissipation duct inlet 38 and the heat dissipation duct outlet 40 are both arranged on the side of the wearing bracket 12 away from the wearing space 130 to prevent the hot air after heat exchange with the heat dissipation component 700 from blowing towards the user.

[0179] The blowing duct 30 and the heat dissipation duct 36 are respectively located on opposite sides of the temperature regulating component 310 at the temperature regulating component 300, that is, the blowing duct 30 is located on the side of the temperature regulating component 310 close to the wearing space 130 in the area of ​​the temperature regulating component 300, and the heat dissipation duct 36 is located on the side of the temperature regulating component 310 away from the wearing space 130 in the area of ​​the temperature regulating component 300. The blowing duct 30 and the heat dissipation duct 36 are separated by the temperature regulating component 310 at the temperature regulating component 300, reducing the risk of mutual interference between the cold air in the blowing duct 30 and the hot air in the heat dissipation duct 36, thereby reducing the influence of the hot air in the heat dissipation duct 36 on the cold wind cooling the user.

[0180] Specifically, a partition bracket 200 is provided inside the neck halter 20. The partition bracket 200 is annular, and the temperature regulating member 310 is fixedly mounted on the inner side of the partition bracket 200, thereby indirectly being fixed to the wearing bracket 12. The partition bracket 200 surrounds the outer periphery of the temperature regulating member 310, and can also, to a certain extent, separate the heat dissipation duct 36 from the blowing duct 30, further reducing the risk of interference between cold air and hot air.

[0181] In one embodiment, the air blowing duct 30 includes a third air duct 46 and a fourth air duct 48. The air blowing fan includes a first air blowing device 500 located in the third air duct 46 and a second air blowing device 600 located in the fourth air duct 48. The heat conducting member 400 is partially located in the third air duct 46 and partially located in the fourth air duct 48. The first air blowing device 500 can drive air flow in the third air duct 46, and the second air blowing device 600 can drive air flow in the fourth air duct 48, which helps increase the air intake and air output of the portable fan 10. In addition, the air flow in the third air duct 46 and the fourth air duct 48 can pass through the heat conducting member 400 to reduce the temperature.

[0182] It can be understood that the third air duct 46 and the fourth air duct 48 may have independent outlets and inlets respectively, or may have the same outlet or inlet.

[0183] In this embodiment, the blowing duct inlet 32 ​​includes a first inlet 54 and a second inlet 56, and the blowing duct outlet 34 includes a first outlet 58 and a second outlet 60. The first inlet 54 and the first outlet 58 are respectively connected to the two ends of the third air duct 46, and the second inlet 56 and the second outlet 60 are respectively connected to the two ends of the fourth air duct 48. The first blowing device 500 is located between the first inlet 54 and the first outlet 58, and the second blowing device 600 is located between the second inlet 56 and the second outlet 60. When the first blowing device 500 is working, the outside air enters the third air duct 46 through the first inlet 54 and flows in the third air duct 46 toward the first outlet 58. During the flow, the outside air will pass through the portion of the heat conducting component 400 located in the third air duct 46, and be discharged from the first outlet 58 and blown toward the user after the temperature is reduced. When the second blowing device 600 is working, the outside air enters the fourth air duct 48 through the second inlet 56 and flows in the fourth air duct 48 toward the second outlet 60. During the flow, the outside air will pass through the portion of the heat conducting component 400 located in the fourth air duct 48, and be discharged from the second outlet 60 and blown toward the user. This allows the portable fan 10 to take in air from different inlets and blow cold air to the user from different outlets, thereby increasing the air intake of the portable fan 10 and at the same time increasing the coverage area of ​​the cold air on the human body, that is, increasing the contact area between the cold air and the human body, thereby enhancing the cooling effect of the portable fan 10.

[0184] The first blowing device 500 and the second blowing device 600 are respectively located on opposite sides of the heat conducting member 400, that is, the heat conducting member 400 is located between the first blowing device 500 and the second blowing device 600. The direction in which the first blowing device 500 drives the airflow through the heat conducting member 400 is opposite to the direction in which the second blowing device 600 drives the airflow through the heat conducting member 400. By installing the first blowing device 500 and the second blowing device 500 and the second blowing device 600 on opposite sides of the heat conducting member 400 and driving the air through the heat conducting member 400 in opposite directions, the layout of the first blowing device 500 and the second blowing device 600 is made more reasonable while ensuring that the airflow driven by the first blowing device 500 and the second blowing device 600 can both pass through the heat conducting member 400. This improves the compactness of the internal structure of the portable fan 10 and prevents the problem of the neck portion 20 being oversized in a local area due to the first blowing device 500 and the second blowing device 600 being located on the same side of the heat conducting member 400.

[0185] Specifically, the first inlet 54 and the second inlet 56, as well as the first outlet 58 and the second outlet 60 are respectively located on opposite sides of the temperature conducting component 400, the inlets of the third air duct 46 and the fourth air duct 48 are respectively located on opposite sides of the temperature conducting component 400, and the outlets of the third air duct 46 and the fourth air duct 48 are also respectively located on opposite sides of the temperature conducting component 400, thereby increasing the distance between the first inlet 54 and the second inlet 56 and the first outlet 58 and the second outlet 60, preventing the distance between the two inlets from being too small, causing the air to interfere with each other when passing through and affecting the air intake volume, and also avoiding the distance between the two outlets from being too small, causing the cold air coverage area to overlap and affecting the cooling effect.

[0186] Preferably, the heat conducting member 400 is located between the first blowing device 500 and the second blowing device 600, and the heat conducting member 400 is located in the middle of the neck hanging portion 20. The first blowing device 500 and the second blowing device 600 are respectively arranged at the two ends of the neck hanging portion 20 close to the handle portion 23, so as to avoid the first blowing device 500, the second blowing device 600 and the heat conducting member 400 being too concentrated in the neck hanging portion 20, thereby facilitating disassembly and assembly operations, and also facilitating the design of forming the third air duct 46 and the fourth air duct 48.

[0187] The third air duct 46 and the fourth air duct 48 are staggered at the height of the wearing bracket 12 at the thermal conductive member 400. Since the direction of airflow through the thermal conductive member 400 in the third air duct 46 is opposite to the direction of airflow through the thermal conductive member 400 in the fourth air duct 48, staggering the third air duct 46 and the fourth air duct 48 at the height of the wearing bracket 12 can reduce the impact of airflow in the third air duct 46 and airflow in the fourth air duct 48 at the thermal conductive member 400, thereby reducing the air output of the portable fan 10.

[0188] In one embodiment, the first entrance 54 and the second entrance 56 are respectively arranged on the side of the neck hanging portion 20 close to the wearing space 130, the first entrance 54 is located on the side of the temperature conducting member 400 away from the first blowing device 500, and the second entrance 56 is located on the side of the temperature conducting member 400 away from the second blowing device 600, that is, the first blowing device 500, the second entrance 56, the temperature conducting member 400, the first entrance 54 and the second blowing device 600 are arranged at intervals along the circumference of the wearing bracket 12, the second entrance 56 is located between the first blowing device 500 and the temperature conducting member 400, and the first entrance 54 is located between the second blowing device 600 and the temperature conducting member 400, that is, the first entrance 54 and the second blowing device 600 are located on the same side of the temperature conducting member 400, and the second entrance 56 and the first blowing device 500 are located on the same side of the temperature conducting member 400. When the first blowing device 500 is working, the outside air enters the third air duct 46 through the first inlet 54, and moves from one side of the heat conducting member 400 to the other opposite side, and then passes through the first blowing device 500 and blows out from the first outlet 58. When the second blowing device 600 is working, the outside air enters the fourth air duct 48 through the second inlet 56, and moves from one side of the heat conducting member 400 to the other opposite side, and then passes through the second blowing device 600 and blows out from the second outlet 60, so that the airflow driven by the first blowing device 500 and the second blowing device 600 can be fully It is in contact with the heat conducting member 400, thereby enhancing the heat exchange effect between the airflow and the heat conducting member 400, and ensuring the cooling effect of the portable fan 10. In addition, the first blowing device 500 is located on the side of the heat conducting member 400 close to the first outlet 58, and the second blowing device 600 is located on the side of the heat conducting member 400 close to the second outlet 60, which reduces the distance between the first blowing device 500 and the first outlet 58 and the second blowing device 600 and the second outlet 60, so that the cold air has stronger power when blowing out from the first outlet 58 and the second outlet 60, ensuring that the cold air can reach the user after being blown out.

[0189] Preferably, the first inlet 54 and the second inlet 56 are staggered in the height direction of the wearing bracket 12, so that the two air flows entering the third air duct 46 and the fourth air duct 48 are staggered when entering, which is conducive to reducing the difficulty of setting the third air duct 46 and the fourth air duct 48.

[0190] Specifically, the first outlet 58 is located on the side of the first blowing device 500 away from the heat conducting member 400, and the second outlet 60 is located on the side of the second blowing device 600 away from the heat conducting member 400, and the first outlet 58 and the second outlet 60 are respectively located on one side of the two handle parts 23 in the height direction of the wearing bracket 12.

[0191] In this embodiment, a first air guide portion 62 and a second air guide portion 64 are provided within the collar portion 20. The first air guide portion 62 and the second air guide portion 64 are located on opposite sides of the heat conducting member 400. The first air guide portion 62 extends from the first inlet 54 toward the heat conducting member 400, and the second air guide portion 64 extends from the second inlet 56 toward the heat conducting member 400. After passing through the first inlet 54, ambient air comes into contact with the first air guide portion 62 and, under the guidance of the first air guide portion 62, moves toward the heat conducting member 400, ultimately moving from one side of the heat conducting member 400 to the other opposite side. Similarly, after passing through the second inlet 56, ambient air comes into contact with the second air guide portion 64 and, under the guidance of the second air guide portion 64, moves toward the heat conducting member 400, ultimately moving from one side of the heat conducting member 400 to the other opposite side. This serves to guide airflow into the third and fourth air ducts 46 and 48, thereby increasing the amount of air entering.

[0192] Specifically, one end of the first air guide portion 62 is connected to the neck hanging portion 20 and the connection portion is located on the side of the first inlet 54 away from the thermal conductor 400, and the other end extends obliquely toward the side of the thermal conductor 400, and the first inlet 54 is located between the thermal conductor 400 and the first air guide portion 62; one end of the second air guide portion 64 is connected to the neck hanging portion 20 and the connection portion is located on the side of the second inlet 56 away from the thermal conductor 400, and the other end extends obliquely toward the other opposite side of the thermal conductor 400, and the second inlet 56 is located between the thermal conductor 400 and the second air guide portion 64, and the first guide portion 62 and the second guide portion 64 are staggered in the height direction of the wearing bracket 12.

[0193] A first escape portion 66 is provided on one side of the thermal conductive member 400, corresponding to the first air guide portion 62. The first air guide portion 62 is inserted into the first escape portion 66. A second escape portion 68 is provided on the other, opposite side of the thermal conductive member 400, corresponding to the second air guide portion 64. The second air guide portion 64 is inserted into the second escape portion 68. Both the first and second escape portions 66 and 68 are notch-shaped and are staggered in the height direction of the wearing bracket 12. After passing through the first inlet 54, outside air is guided by the first air guide portion 62 into the notch-shaped first escape portion 66 and then flows along the third air duct 46. Outside air then passes through the second inlet 56, guided by the second air guide portion 64, into the notch-shaped second escape portion 68 and then flows along the fourth air duct 48. This reduces the amount of air that diffuses outward after passing through the first and second inlets 54 and 56, thereby increasing the air volume entering the third and fourth air ducts 46 and 48.

[0194] Specifically, the outer contour of the heat conducting member 400 is formed to be roughly rectangular, and the first avoidance portion 66 and the second avoidance portion 68 are notches provided at two corners of the rectangle on a diagonal line, thereby forming a staggered effect.

[0195] In another embodiment, the first outlet 58 and the second outlet 60 are respectively arranged on the side of the neck hanging part 20 close to the wearing space 130, the first outlet 58 is located on the side of the temperature conducting member 400 away from the first blowing device 500, and the second outlet 60 is located on the side of the temperature conducting member 400 away from the second blowing device 600, that is, the first blowing device 500, the second outlet 60, the temperature conducting member 400, the first outlet 58 and the second blowing device 600 are arranged at intervals along the circumference of the wearing bracket 12, the second outlet 60 is located between the first blowing device 500 and the temperature conducting member 400, and the first outlet 58 is located between the second blowing device 600 and the temperature conducting member 400, that is, the first outlet 58 and the second blowing device 600 are located on the same side of the temperature conducting member 400, and the second outlet 60 and the first blowing device 500 are located on the same side of the temperature conducting member 400. When the first blowing device 500 and the second blowing device 600 are working, they can both move the airflow from one side of the heat conducting member 400 to the other side, so that the airflow can fully contact the heat conducting member 400 to enhance the heat exchange effect between the airflow and the heat conducting member 400. Moreover, the first blowing device 500 is located on the side of the heat conducting member 400 away from the first outlet 58, and the second blowing device 600 is located on the side of the heat conducting member 400 away from the second outlet 60, which reduces the distance between the first blowing device 500 and the first inlet 54 and the second blowing device 600 and the second inlet 56, so that the first blowing device 500 and the second blowing device 600 can form a greater suction force at the first inlet 54 and the second inlet 56 to increase the air intake.

[0196] Preferably, the first outlet 58 and the second outlet 60 are staggered in the height direction of the wearing bracket 12, so that the airflows blown out from the first outlet 58 and the second outlet 60 are staggered in the height direction to contact the user's skin at different heights, so as to increase the coverage area of ​​the cold air on the human body.

[0197] Specifically, the first entrance 54 and the second entrance 56 are both located on the side of the neck hanging part 20 away from the wearing space 130, and the first entrance 54 and the second entrance 56 are arranged at intervals along the circumference of the wearing bracket 12. The first entrance 54 is close to the first blowing device 500, and the second entrance 60 is close to the second blowing device 600.

[0198] In this embodiment, a first air guide portion 62 and a second air guide portion 64 are provided within the neck portion 20. The first air guide portion 62 and the second air guide portion 64 are located on opposite sides of the heat conducting member 400. The first air guide portion 62 extends from the first outlet 58 toward the heat conducting member 400, and the second air guide portion 64 extends from the second outlet 60 toward the heat conducting member 400. When the airflow within the third air duct 46 moves from the side of the heat conducting member 400 away from the first outlet 58 to the first air guide portion 62, the first air guide portion 62 can guide the airflow toward the first outlet 58. When the airflow within the fourth air duct 48 moves from the side of the heat conducting member 400 away from the second outlet 60 to the second air guide portion 64, the second air guide portion 64 can guide the airflow toward the second outlet 60, thereby guiding the airflow to be blown outward from the first outlet 58 and the second outlet 60 to increase the airflow volume.

[0199] Specifically, one end of the first air guide portion 62 is connected to the neck hanging portion 20 and the connection portion is located on the side of the first outlet 58 away from the thermal conductor 400, and the other end extends obliquely toward the side of the thermal conductor 400, and the first outlet 58 is located between the thermal conductor 400 and the first air guide portion 62; one end of the second air guide portion 64 is connected to the neck hanging portion 20 and the connection portion is located on the side of the second outlet 60 away from the thermal conductor 400, and the other end extends obliquely toward the other opposite side of the thermal conductor 400, and the second outlet 60 is located between the second air guide portion 64 and the thermal conductor 400, and the first guide portion 62 and the second guide portion 64 are staggered in the height direction of the wearing bracket 12.

[0200] A first avoidance portion 66 is provided on one side of the heat conducting member 400, corresponding to the first air guide portion 62. The first air guide portion 62 is inserted into the first avoidance portion 66. A second avoidance portion 68 is provided on the other opposite side of the heat conducting member 400, corresponding to the second air guide portion 64. The second air guide portion 64 is inserted into the second avoidance portion 68. Both the first avoidance portion 66 and the second avoidance portion 68 are notch-shaped, and are staggered in the height direction of the wearing bracket 12. The airflow in the third air duct 46, guided by the first air guide portion 62, first enters the notch-shaped first avoidance portion 66 before being blown out of the first outlet 58. The airflow in the fourth air duct 48, guided by the second air guide portion 64, first enters the notch-shaped second avoidance portion 68 before being blown out of the second outlet 60. This reduces the diffusion of the airflow from the first outlet 58 and the second outlet 60, thereby increasing the airflow volume of the third air duct 46 and the fourth air duct 48.

[0201] Specifically, the outer contour of the heat conducting member 400 is formed to be roughly rectangular, and the first avoidance portion 66 and the second avoidance portion 68 are notches provided at two corners of the rectangle on a diagonal line, thereby forming a staggered effect.

[0202] In one embodiment, the heat dissipation assembly 700 is located between the heat dissipation duct inlet 38 and the heat dissipation duct outlet 40, so that the airflow passing through the heat dissipation assembly 700 as it moves from the heat dissipation duct inlet 38 toward the heat dissipation duct outlet 40 will exchange heat with the heat dissipation assembly 700. The heat dissipation fan 47 is located between the heat dissipation assembly 700 and the heat dissipation duct outlet 40. The heat dissipation duct inlet 38 is located on the side of the heat dissipation assembly 700 away from the heat dissipation fan 47. This reduces the distance between the heat dissipation fan 47 and the heat dissipation duct outlet 40, giving the airflow greater momentum when it is discharged from the heat dissipation duct outlet 40, thereby increasing the airflow volume.

[0203] Specifically, there are two heat dissipation air duct outlets 40 , and the two heat dissipation air duct outlets 40 are arranged at intervals along the circumference of the wearing bracket 12 .

[0204] In another embodiment, the heat dissipation assembly 700 is located between the heat dissipation duct inlet 38 and the heat dissipation duct outlet 40, so that the airflow passing through the heat dissipation assembly 700 when moving from the heat dissipation duct inlet 38 toward the heat dissipation duct outlet 40 will exchange heat with the heat dissipation assembly 700. The heat dissipation fan 47 is located between the heat dissipation duct inlet 38 and the heat dissipation assembly 700, and the heat dissipation duct outlet 40 is located on the side of the heat dissipation assembly 700 away from the heat dissipation fan 47. This reduces the distance between the heat dissipation fan 47 and the heat dissipation duct inlet 38, allowing the heat dissipation fan 47 to generate greater suction at the heat dissipation duct inlet 38 when in operation, thereby increasing the amount of air entering.

[0205] Preferably, the neck hanging portion 20 protrudes along the height direction of the wearing bracket 12 to form a protrusion 69, and the heat dissipation fan 47 is installed in the protrusion 69. By making the neck hanging portion 22 protrude to form the protrusion 69, the overall volume of the neck hanging portion 20 is increased, thereby increasing the internal space of the neck hanging portion 20, so that the temperature control component 300, the fan component 16, the blowing air duct 30, the heat dissipation air duct 36, etc. are arranged on the neck hanging portion 20. In addition, the protrusion 69 protrudes along the height direction of the wearing bracket 12 to avoid increasing the overall thickness of the wearing bracket 12.

[0206] Specifically, the protrusion 69 protrudes downward from the middle of the neck hanging portion 20, the heat dissipation fan 47 is located on one side of the temperature adjustment component 300 along the height direction of the wearing bracket 12, and the first blowing device 500 and the second blowing device 600 are located on opposite sides of the temperature adjustment component 300 along the circumference of the wearing bracket 12, that is, the first blowing device 500, the second blowing device 600 and the heat dissipation fan 47 are respectively located on different sides of the temperature adjustment component 300.

[0207] In one embodiment, the temperature conducting member 400 includes a temperature conducting plate 70 connected to the temperature regulating member 310 and a plurality of temperature conducting fins 72 located on the side of the temperature conducting plate 70 away from the temperature regulating member 310. Specifically, the temperature conducting plate 70 is fixed to the side of the temperature regulating member 310 close to the wearing space 130, and the temperature conducting fins 72 are located on the side of the temperature conducting plate 70 close to the wearing space 130. The cold energy generated on the side of the temperature regulating member 310 close to the wearing space 130 can be transferred to the temperature conducting plate 70, and then transferred by the temperature conducting plate 70 to the plurality of temperature conducting fins 72, so as to increase the contact area between the temperature conducting member 400 and the airflow and enhance the heat exchange effect.

[0208] Multiple thermal conductive fins 72 are arranged at intervals to form a cold air flow channel 73 between two adjacent thermal conductive fins 72. The extension direction of the cold air flow channel 73 is the same as the extension direction of the blowing air duct 30, so that the air flow in the cold air flow channel 73 is smoother, thereby increasing the air output and reducing noise.

[0209] The heat dissipation assembly 700 includes a heat dissipation plate 74 connected to the temperature regulating component 310 and a plurality of heat dissipation fins 242 located on the side of the heat dissipation plate 74 away from the temperature regulating component 310. Specifically, the heat dissipation plate 74 is fixed to the side of the temperature regulating component 310 away from the wearing space 130, and the plurality of heat dissipation fins 242 are located on the side of the heat dissipation plate 74 away from the wearing space 130. The heat generated on the side of the temperature regulating component 310 away from the wearing space 130 can be transferred to the heat dissipation plate 74, and then transferred from the heat dissipation plate 74 to the plurality of heat dissipation fins 242, so as to increase the contact area between the heat dissipation assembly 700 and the airflow and enhance the heat exchange effect.

[0210] Multiple heat sinks 242 are arranged at intervals to form a heat dissipation channel 78 between two adjacent heat sinks 242. The extension direction of the heat dissipation channel 78 is the same as the extension direction of the blowing duct 30, so that the air flow flows more smoothly in the heat dissipation channel 78, thereby enhancing the heat dissipation effect of the heat dissipation component 700.
