DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] An embodiment of the utility model 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-mounted fan.

[0030] like Figure 1 and Figure 2 As shown, the portable fan provided by the embodiment of the utility model includes, for example, a housing 100 , a partition bracket 200 , a temperature adjustment component 300 , a temperature conducting member 400 and a first blowing device 500 .

[0031] Specifically, the housing 100 has, for example, a housing cavity 101, a first air outlet 104, and a heat dissipation port 105. The housing 100, for example, is formed with a neck-wearing space 130, and the neck-wearing space 130 allows the portable fan 10 to be worn on the neck of a human body. The housing 100, for example, includes a first housing 110 and a second housing 120 that are arranged opposite to each other, the first housing 110 is arranged close to the neck-wearing space 130, the second housing 120 is connected to a side of the first housing 110 away from the neck-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, and the heat dissipation port 105 is, for example, arranged on the second housing 120, and the specific positions of the first air outlet 104 and the heat dissipation port 105 are not limited here.

[0032] like Figure 5 As shown, 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 neck-wearing space 130 and a second accommodating chamber 103 away from the neck-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, wherein the partition bracket 200 is used to place the temperature control component 300 and other components and to divide the accommodating chamber 101 in the shell 100 into two parts, so that after the temperature control component 300, the heat 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.

[0033] The temperature control component 300 is, for example, a TEC (Thermoelectric cooler) or other semiconductor cooling 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 orthographic 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.

[0034] The heat conducting member 400 is, for example, disposed in the first accommodating cavity 102, and is thermally connected to the temperature regulating assembly 300. The heat conducting member 400 is, for example, made of a metal material such as aluminum alloy or copper, and is, for example, in the shape of a fin or other shapes, for transferring the cold energy generated by the temperature regulating assembly 300 to the airflow, thereby enhancing the cooling effect.

[0035] Specifically, the first blowing device 500 is used to blow out wind. The wind blown out 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 temperature conducting member 400. At the same time, the wind blown out by the first blowing device 500 can also be connected to the second accommodating chamber 103, and the airflow is guided out through the heat dissipation port 105 to take away the heat generated by the temperature regulating component 300 when it is working, and blow it out from the heat dissipation port 105 to ensure that the heat generated by the temperature regulating component 300 when it is working is dissipated in time, so that the temperature regulating component 300 can maintain normal operation to ensure the cooling effect of the portable fan 10. In some embodiments, Figure 3 As shown, the first blowing device 500 includes, for example, a first fan 501 for blowing air, and the air blown by the first fan 501 is 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 through the temperature conducting member 400. Figure 1 and Figure 2 As shown, 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 through the heat conducting member 400 after heat exchange, 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 be blown 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. Figure 1 and Figure 2 As shown, 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 adjustment component 300 when it is working and discharge it through the heat dissipation port 105. In this embodiment, since the heat dissipation port 105 is used to discharge the heat generated by the temperature adjustment component 310 when it is working, the position of the heat dissipation port 105 cannot be discharged toward the human body, so the position of the heat dissipation port 105 is set on the outer side of the shell 100 away from the neck wearing space 130, that is, away from the outer side of the human body for exhaust and heat dissipation, so that the heat dissipation port 105 will not affect the human body's cooling experience, and enhance the user's cooling experience. In some embodiments, there may be no blowing device blowing air to the second accommodating chamber 103, and the heat in the second accommodating chamber 103 is discharged from the heat dissipation port by air heat exchange.

[0036] In the embodiment of the utility model, 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 temperature conductive component 400 is connected to the temperature regulating component 300 by heat conduction. A part of the airflow blown out from the first air outlet 104 by the first blowing device 500 flows through the temperature conductive component 400 in the first accommodating chamber 102. The temperature conductive component 400 transfers the cooling capacity generated by the temperature regulating component 300 to the airflow. The airflow exchanges heat with the temperature conductive component 400, so that the airflow can be quickly cooled and blown out from the first air outlet 104. 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 have a more comfortable experience during use.

[0037] like Figure 2 , Figure 5 and Figure 6 As shown, the thermostat assembly 300 includes, for example, a plurality of thermostats 310, for example, at least two thermostats 310, and 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, for example, configured to fit the shape of a human neck, and 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 the space. The above design allows for the arrangement of more thermostats 310, resulting in a greater cooling capacity and a better cooling effect. Of course, in other embodiments, the thermostat assembly 300 may also include only one thermostat 310.

[0038] like Figure 2 As shown, an angle is formed between two adjacent temperature-regulating components 310, that is, at least one group of two adjacent temperature-regulating components 310 among the multiple temperature-regulating components 310 are not arranged in a straight line, but are set at an angle, so that in the same space, the two temperature-regulating components 310 set at an angle can be arranged in a longer area, so that the heat conducting component 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.

[0039] Specifically, Figure 6As shown, the thermal conductive component 400 includes, for example, a mounting portion 401 and a thermal conductive body 402. The mounting portion 401 is provided with a bending portion 403. The mounting portion 401 is, for example, a thermal conductive sheet that is bent, or a bent shape formed by splicing two thermal conductive sheets. The mounting portion 401 is, for example, made of metal materials such as aluminum alloy or copper. The bending portion 403 is located between the two temperature regulating components 310 that form an angle. The mounting portion 401 connects the plurality of temperature regulating components 310 by thermal conduction, so that the thermal conductive component 400 is arranged in close contact with the plurality of temperature regulating components 310, so that the thermal conduction effect between the thermal conductive component 400 and the plurality of temperature regulating components 310 is better. The thermal conductive body 402 includes a plurality of thermal conductive fins, and the plurality of thermal conductive fins are arranged at intervals from each other 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 that is away from the temperature regulating component 300, and is, for example, made of metal materials such as aluminum alloy or copper.

[0040] 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, and the first blade 510 is used to generate an airflow that flows into the first accommodating chamber 102, and flows through the thermal conductive 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, and 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, disposed 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.

[0041] In another embodiment, the first blowing device 500 includes, for example, two independently arranged fans, and the two fans correspond 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 heat conducting member 400 for heat exchange, and is blown out from the first air outlet 104, so that the airflow generated by the first fan is effectively cooled, 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 port 105 to dissipate the heat generated when the thermostat 310 is working.

[0042] Specifically, the temperature regulating component 300 has a cooling end and a heat dissipation end opposite to each other, the cooling end is located on one side of the temperature regulating component 300 close to the first accommodating cavity 102, and the temperature conducting member 400 is thermally connected to the cooling end of the temperature regulating component 300. Figure 3 , Figure 5 and Figure 6 As shown, a heat dissipation component 700 is provided in the second accommodation cavity 103, and the heat dissipation component 700 is, for example, thermally connected to the heat dissipation end of the temperature regulating component 300. Of course, in other embodiments, the heat conducting member may be thermally connected to the heat dissipation end of the temperature regulating component 300, so that the wind blown out from the first air outlet 104 is hot wind, which is convenient for users to use portable fans for heating in winter.

[0043] The heat conduction connection in this embodiment refers to the 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 provided between the temperature adjustment component 300 and the heat dissipation component 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 make the temperature adjustment component 300 and the temperature conduction member 400 or the temperature adjustment component 300 and the heat dissipation component 700 indirectly contact to form heat transfer.

[0044] In some embodiments, the portable fan 10 further includes, for example, a second blowing device 600, which is, for example, disposed in the second accommodating chamber 103. The second blowing device 600 is used to discharge the heat generated by the temperature adjustment component 300 from the heat dissipation port 105 through the heat dissipation component 700, so as to dissipate the heat generated by the temperature adjustment component 300 when working more promptly, so that the temperature adjustment component 300 maintains normal operation to 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 both ends of the partition bracket 200, and the first blowing device 500 and the second blowing device 600 blow air to the heat dissipation component 700 located between the first blowing device 500 and the second blowing device 600.

[0045] Specifically, the heat dissipation component 700 is, for example, located in the second accommodating cavity 103 and disposed between the heat dissipation port 105 and the second blowing device 600, and the heat dissipation component 700 is disposed corresponding to the temperature adjustment component 300. The heat dissipation component 700 is, for example, made of a metal material such as aluminum alloy or copper, and is, for example, in the shape of a fin or other shape, and is used to transfer the heat generated by the temperature adjustment component 300 to the airflow, so as to dissipate the heat generated by the temperature adjustment component 300 when it is working more promptly.

[0046] 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 shape of a sheet, and one or more heat dissipation elements can be provided. When there is only one substrate 702, multiple heat dissipation elements are provided on the substrate 702, and when multiple substrates 702 are provided, one heat dissipation element 701 can be provided corresponding to one substrate 702, and the substrate 702 is thermally connected to the temperature control component 300 by thermal conduction, so that the multiple heat dissipation elements 701 are respectively thermally connected to the temperature control component 300 by thermal conduction, and the heat dissipation element 701 is composed of multiple heat dissipation fins, and a heat dissipation channel is formed between each adjacent two heat dissipation fins. The substrate 702 and the heat dissipation element 701 are made of materials with high thermal conductivity, such as aluminum alloy or copper, and a partition 703 is provided between two adjacent heat dissipation elements 701; the partition 703 is provided corresponding to the heat dissipation port 105. In some embodiments, Figure 4 , Figure 7 and Figure 8As shown, a partition 703 is provided between two adjacent heat sinks 701 that are angled among the multiple heat sinks 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 sinks 701, and is used to separate the airflow in the heat dissipation channels of the two adjacent heat sinks 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 flowing 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 the 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 passing through the two heat sinks 701 so that it can be discharged from the heat dissipation port 105 in a timely manner.

[0047] It should be noted that the number of the heat sinks 701 and the temperature conducting members 400 can be set according to the number of the temperature regulating members 310 . The number of the temperature regulating members 310 can be set according to the actual structure of the product and user requirements, and is not limited here.

[0048] 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.

[0049] The partition bracket 200 includes a partition 210 and two side panels 220, and the accommodating cavity 101 is divided 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 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 temperature conductive component 400 and the heat dissipation component 700 are respectively arranged on the left and right sides of the partition 210, and the temperature conductive 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 temperature conductive 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.

[0050] Refer to Figure 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 disposed on a side of the first housing 110 close to the heat conducting member 400. The air guide 230 is, for example, Figure 2As shown, two relatively arranged air guide plates are provided, and an air outlet duct is formed between the two air guide plates, the partition bracket 200 and the first shell body 110. The air guide member 230 extends from the position where the temperature regulating member 310 is installed on the partition bracket 200 to the position of the partition bracket 200 close to the first air outlet 104, that is, the air guide member 230 is located at the end of the temperature guiding member 400 away from the first blowing device 500. The air guide member 230 is used to guide the wind generated by the first blowing device 500 to be blown out from the first air outlet 104 through the air outlet duct, so that the cooled wind is blown out from the first air outlet 104 in the extension direction of the air guide member 230, thereby further improving the cooling effect.

[0051] In some embodiments, Figure 3 As shown, the partition bracket 200 is provided with a guide member 111, for example, which is provided on a side of the first blowing device 500 close to the heat dissipation assembly 700.
