DETAILED DESCRIPTION

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0026] The present utility model embodiment provides a wearable fan 100, such as Figure 1 , Figure 2 and Figure 3 As shown, the wearable fan 100 includes two shells 110 connected to each other, each shell 110 is respectively provided with a turbofan 120 and an air duct 130 corresponding to the turbofan 120, the shell 110 is provided with an air outlet 112 connected to the air duct 130, the shell 110 is also provided with an air inlet 113 corresponding to the turbofan 120, and a semiconductor refrigerator 140 corresponding to the turbofan 120, the semiconductor refrigerator 140 is located outside the shell 110, and a gap is formed between the semiconductor refrigerator 140 and the air inlet 113, and the cooling surface of the semiconductor refrigerator 140 is arranged away from the shell 110.

[0027] Specifically, through the two mutually connected shells 110 and the turbofan 120 arranged in each shell 110, when the turbofan 120 rotates, the gas flows perpendicular to the rotating shaft and enters the air duct 130 corresponding to the fan, and finally blows out from the air outlet 112. In addition, by providing an air inlet 113 corresponding to the turbofan 120 and a semiconductor refrigerator 140 corresponding to the turbofan 120 on the shell 110, the semiconductor refrigerator 140 is located outside the shell 110, and when the wearable fan 100 is worn on the corresponding part of the human body, the semiconductor refrigerator 140 is located between the human body and the shell 110, so as to avoid the shell 110 directly attached to the skin of the human body, which is conducive to reducing the contact area with the skin and ensuring the normal circulation of air on the skin surface. At the same time, the cooling surface of the semiconductor refrigerator 140 is arranged away from the shell 110, so that the cooling surface of the semiconductor refrigerator 140 can be in contact with the skin, so as to achieve the purpose of cooling the skin and improve the comfort when wearing.

[0028] It can be understood that by forming a gap between the semiconductor refrigerator 140 and the air inlet 113, when the turbofan 120 rotates, the heat generated by the heat dissipation surface of the semiconductor refrigerator 140 can be absorbed into the air inlet 113. While dissipating the heat from the heat dissipation surface of the semiconductor refrigerator 140, the heat can also be absorbed into the turbofan 120 and flow along the air duct 130. In the process of flowing along the air duct 130, the heat in the air flow is exchanged and dissipated with the outside world, thereby preventing the wind finally blown out from the air outlet 112 from being hot air, which is beneficial to ensuring the coolness of the blown air.

[0029] It should be noted that the embodiment of the present application does not impose any specific restrictions on the structure of the shell 110. For example, the shell 110 can adopt a straight plate structure to be applied to a handheld fan, and the shell 110 can also adopt a curved structure to be applied to a neck fan or a waist fan. In actual applications, it can be flexibly set according to actual needs.

[0030] The wearable fan 100 provided in the embodiment of the present application is conducive to adapting to more usage scenarios through two interconnected shells 110 to ensure wearing comfort. By arranging a turbofan 120 and an air duct 130 corresponding to the turbofan 120 in each shell 110, when the turbofan 120 is running, each shell 110 can blow air outward through the air outlet 112 to ensure the coverage area of ​​the wind force. In addition, by arranging a semiconductor refrigerator 140 corresponding to the turbofan 120 outside the shell 110, and forming a gap between the semiconductor refrigerator 140 and the air inlet 113, when the turbofan 120 is running, the airflow can enter the air inlet 113 along the above gap. Since the cooling surface of the semiconductor refrigerator 140 is arranged away from the shell 110, the heating surface of the semiconductor refrigerator 140 faces the air inlet 113. In this way, the airflow entering the air inlet 113 along the gap can take away the heat generated by the heating surface to ensure the stable operation of the semiconductor refrigerator 140. In the process of the airflow flowing along the air duct 130, heat exchange occurs with the outside world, and the heat taken away by the airflow is dissipated, and finally cool wind is blown out from the air outlet 112, thereby avoiding hot wind blowing to the user. At the same time, the semiconductor cooler 140 is located outside the shell 110. When wearing the wearable fan 100, the semiconductor cooler 140 can not only cool the skin, but also isolate the direct contact between the skin and the shell 110, reduce the contact area between the shell 110 and the skin, and reduce the stuffiness of the skin in the contact area (wearing area), which is conducive to improving the user experience.

[0031] like Figure 4 As shown, the semiconductor cooler 140 includes a connecting seat 142 and a cooler body 144 arranged in the connecting seat 142, a heat conductive sheet 146 is arranged on the side of the cooler body 144 facing away from the shell 110, a heat sink 148 is arranged on the side of the cooler body 144 facing the shell 110, and the semiconductor cooler 140 is connected to the shell 110 via the heat sink 148.

[0032] Specifically, the connecting seat 142 and the refrigerator body 144 arranged in the connecting seat 142 are conducive to protecting the refrigerator body 144 and preventing the refrigerator body 144 from being damaged by external influences. In addition, the heat conducting sheet 146 arranged on the side of the refrigerator body 144 away from the shell 110 is conducive to heat exchange between the cooling surface of the refrigerator body 144 and the skin, so as to ensure the cool touch at the position where the semiconductor refrigerator 140 contacts the skin. At the same time, the heat sink 148 arranged on the side of the refrigerator body 144 facing the shell 110 is conducive to ensuring that the heat generated by the heat dissipation surface of the refrigerator body 144 is dissipated through the heat sink 148 in time. When the semiconductor refrigerator 140 is connected to the shell 110, it is connected to the shell 110 through the heat sink 148, which is conducive to simplifying the connection form. It can be understood that the heat conducting sheet 146 and the heat sink 148 are respectively connected to the connecting seat 142 to ensure the reliability of the structure of the semiconductor refrigerator 140 itself.

[0033] Please continue to refer to Figure 4 The heat sink 148 includes a heat dissipation portion 1481 attached to the refrigerator body 144, a connecting portion 1482 connected to the heat dissipation portion 1481, and a guide portion 1484 arranged on the heat dissipation portion 1481, and a plurality of guide plates 1486 are arranged on the outer circle of the guide portion 1484, wherein the connecting portion 1482 is connected to the connecting seat 142, and a heat dissipation protrusion 1483 is arranged on the side of the heat dissipation portion 1481 facing the shell 110.

[0034] Specifically, when the heat sink 148 is connected to the connection seat 142, it is connected to the connection seat 142 through the connection part 1482, and the connection part 1482 is arranged at the edge of the heat sink 1481. The connection part 1482 and the connection seat 142 can be connected in the form of snap-fit ​​connection or in the form of bonding, as long as the reliability of the connection is guaranteed. The guide part 1484 arranged on the heat sink 1481 and the guide piece 1486 arranged on the outer ring of the guide part 1484 cooperate to facilitate the airflow generated at the gap to smoothly enter the air inlet 113. In addition, the heat dissipation protrusion 1483 arranged on the side of the heat sink 1481 facing the housing 110 is conducive to increasing the heat dissipation area of ​​the heat sink 1481 and improving the heat dissipation capacity.

[0035] like Figure 4As shown, the guide portion 1484 is a hollow structure, and a connecting column 1487 is further provided on the heat dissipation portion 1481, and the connecting column 1487 is located in the guide portion 1484. A connecting hole 114 corresponding to the connecting column 1487 is provided on the shell 110, and a limiting column 1488 is also provided on the guide portion 1484. A limiting hole 115 corresponding to the limiting column 1488 is provided on the shell 110, and the connecting column 1487 and the connecting hole 114 are connected by fasteners, and the limiting column 1488 and the limiting hole 115 are snap-connected, and a plurality of air inlets 113 are provided, which correspond to the outer ring of the guide portion 1484.

[0036] Specifically, by setting the connecting column 1487 in the guide part 1484, it is only necessary to make the connecting column 1487 correspond to the connecting hole 114 on the shell 110, so that the fastener can pass through the connecting hole 114 and connect with the connecting column 1487, thereby realizing the connection between the semiconductor refrigerator 140 and the shell 110. Among them, the fastener can be a screw. When the semiconductor refrigerator 140 is connected to the shell 110, in order to ensure the accuracy of the relative position, by setting a limiting column 1488 on the guide part 1484, and setting a limiting hole 115 corresponding to the limiting column 1488 on the shell 110, the relative position of the semiconductor refrigerator 140 and the shell 110 is limited in the form of the engagement connection between the limiting column 1488 and the limiting hole 115. In addition, the air inlet 113 is set in multiple numbers, and corresponds to the outer ring of the guide part 1484, which is conducive to ensuring that the airflow smoothly enters the air inlet 113, so as to ensure the air intake through the turbofan 120.

[0037] like Figure 5 Therefore, the air duct 130 includes a first half body 132 and a second half body 134 that are interlocked with each other. A docking port corresponding to the turbo fan 120 and an opening 136 corresponding to the air outlet 112 are formed between the first half body 132 and the second half body 134 .

[0038] Specifically, the first half body 132 and the second half body 134 are interlocked with each other, which is conducive to improving the convenience of assembling the air duct 130. A docking port corresponding to the turbofan 120 is formed between the first half body 132 and the second half body 134, so that the airflow perpendicular to the rotation axis generated by the turbofan 120 is introduced into the air duct 130 and flows out through the opening 136 to correspond to the air outlet 112 of the housing 110, thereby achieving the purpose of blowing air through the air outlet 112 of the housing 110.

[0039] like Figure 1 As shown, the air outlet 112 is located on one side of the housing 110 in the width direction.

[0040] Specifically, the air outlet 112 is located on one side of the housing 110 in the width direction, which is beneficial for the wind direction of the air outlet 112 to be parallel to the skin during use, and can increase the blowing area of ​​the skin. It can be understood that the air outlet 112 can be set on at least one side of the housing 110 in the width direction, and according to actual use, the air outlet 112 can also be set on both sides of the housing 110 in the width direction.

[0041] like Figure 1 As shown, a plurality of air holes 116 are disposed on the housing 110 . The air holes 116 and the air inlet 113 are located on opposite sides of the housing 110 . The air holes 116 are disposed corresponding to the turbofan 120 .

[0042] Specifically, by setting air holes 116 corresponding to the turbofan 120 on the shell 110, not only can external impurities be prevented from entering the interior of the shell 110 and protecting the turbofan 120, but the air intake at the turbofan 120 can also be increased to increase the air output at the air outlet 112, thereby improving the blowing effect.

[0043] like Figure 1 As shown, the wearable fan 100 further includes a hinge 150 , and the hinge 150 includes a first connecting piece 152 and a second connecting piece 154 that are rotatably connected, and the first connecting piece 152 and the second connecting piece 154 are respectively connected to the two housings 110 .

[0044] Specifically, by connecting the first connecting piece 152 and the second connecting piece 154 to the two shells 110 respectively, it is helpful to change the connection form between the two shells 110 to better suit people of different body shapes, thereby improving applicability during use.

[0045] In an optional embodiment of the present application, a battery is disposed in at least one housing 110, and the battery is electrically connected to the turbofan 120, such as Figure 6 As shown, the housing 110 is also provided with a charging socket 160 electrically connected to the battery.

[0046] Specifically, a battery can be provided in one of the housings 110 to power the turbo fan 120. Batteries can also be provided in both housings 110 to improve the endurance of the wearable fan 100. When batteries are provided in both housings 110, the two batteries need to be provided in series. In addition, a charging socket 160 electrically connected to the battery is also provided on the housing 110 to facilitate charging of the battery.

[0047] like Figure 6As shown, the housing 110 includes a first protective shell 117, a second protective shell 118 and a third protective shell 119. The second protective shell 118 and the third protective shell 119 are respectively connected to the first protective shell 117, and the second protective shell 118 and the third protective shell 119 are butt-jointed.

[0048] Specifically, the first protective shell 117 is located on the outside of the housing 110 to ensure the overall flatness of the housing 110. The second protective shell 118 and the third protective shell 119 are located on the inside of the housing 110. After the components in the housing 110 are assembled and aligned, the second protective shell 118 and the third protective shell 119 can be connected to the first protective shell 117 respectively, and the second protective shell 118 and the third protective shell 119 are docked to ensure that the components inside the housing 110 are protected. The above form can also reduce the difficulty of assembly and improve assembly efficiency.

[0049] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
