[0042] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0043] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0044] Figure 1 It is a structural schematic diagram of a neck-hanging fan provided in an embodiment of the present application; Figure 2 yes Figure 1 A schematic diagram of the structure of the middle part mechanism (for example, the left air outlet mechanism); Figure 3 yes Figure 2 Exploded diagram of Figure 1 , Figure 2 and Figure 3As shown, the neck-hanging fan includes a housing 1 and a fan assembly 2. The housing 1 has a containing space 116, and an air inlet 111 and an inner air outlet 112 are provided on the inner side 114 of the housing 1, and a first outer air outlet 113 is provided on the side 115 of the housing 1, wherein the inner side 114 and the side 115 are adjacent to each other; the fan assembly 2 is located in the containing space 116, and is configured to suck air from the air inlet 111 and blow air from the inner air outlet 112 and the first outer air outlet 113. The air outlet direction of the inner air outlet 112 intersects with the air outlet direction of the first outer air outlet 113, and the extending length direction of the inner air outlet 112 intersects with the extending length direction of the first outer air outlet 113.

[0045] The neck-hanging fan provided in the embodiment of the present application can blow air and dissipate heat to the user from different directions by respectively providing an inner air outlet 112 and a first outer air outlet 113 with different air outlet directions on the inner portion 114 and the side portion 115 of the shell 1, and due to the different positions at which the inner air outlet 112 and the first outer air outlet 113 are provided, the inner air outlet 112 and the first outer air outlet 113 can blow air and dissipate heat to the user from different positions. For example, the inner air outlet 112 provided on the inner portion 114 can blow air to the user's neck from the inside, and the first outer air outlet 113 provided on the side portion 115 can blow air to the user's head from the outside, thereby improving the heat dissipation efficiency.

[0046] In the embodiment of the present application, the "inside" can be understood as the side of the housing 1 that is close to the user's neck when the user uses the neck-hanging fan; the "outside" is opposite to the "inside", and the outside of the fan is farther away from the user's neck than the inside. Therefore, the inner part 114 is the part of the housing 1 that fits the user's neck, and the side part 115 can be connected to the inner part 114 and bend relative to the inner part 114 to extend in a direction away from the user's neck. The direction in which the side part 115 bends and extends relative to the inner part 114 can be understood as the thickness direction T of the fan. The width direction of the inner part 114 can be understood as the width direction W of the fan, and the direction in which the fan extends from the end to the middle can be understood as the length direction L of the fan. The air inlet 111 can be opened at the end of the fan.

[0047] In the embodiment of the present application, the length direction of the air outlet can be understood as the direction from one end (e.g., the head end) of the air outlet to the other end (e.g., the tail end). In some embodiments, the inner air outlet 112 is a straight line extending across the width direction of the inner portion 114; the first outer air outlet 113 can be an arc, and its extension length direction can be perpendicular to the width direction of the inner portion 114. For example, the first outer air outlet 113 can extend from the end of the fan to the middle along the outer contour of the fan.

[0048] like Figure 1As shown, the fan is a plane-symmetrical structure, and the air inlet 111, the inner air outlet 112 and the first outer air outlet 113 are symmetrically distributed on both sides of the fan. Exemplarily, the fan may include a left air outlet mechanism 100 and a right air outlet mechanism 200, which are symmetrically arranged and can be connected together by a connecting mechanism 300. In some embodiments, the left air outlet mechanism 100 and the right air outlet mechanism 200 can be respectively hinged to the connecting mechanism 300, so that the ends of the left air outlet mechanism 100 and the right air outlet mechanism 200 away from the connecting mechanism 300 can rotate closer to or away from each other.

[0049] For ease of understanding, the following detailed description is given by taking one of the left air outlet mechanism 100 and the right air outlet mechanism 200 (for example, the left air outlet mechanism 100 ) as an example.

[0050] As described above, the inner air outlet 112 and the first outer air outlet 113 blow air to the neck and head of the user from different positions and directions, so as to further expand the blowing area of ​​the fan. Figure 1 and Figure 2 As shown, the side portion 115 of the housing 1 is further provided with a second outer air outlet 1212, and the second outer air outlet 1212 is located on a side of the first outer air outlet 113 away from the inner portion 114. Figure 1 and Figure 2 It can be seen that the inner air outlet 112, the first outer air outlet 113 and the second outer air outlet 1212 are arranged in sequence from the inside to the outside along the width direction of the fan (left air outlet mechanism 100), so that when the fan is hung on the user's neck for use, the blowing area of ​​the fan in the width direction (left and right sides of the user) is expanded, thereby improving the heat dissipation efficiency of the fan.

[0051] In addition, if Figure 1 and Figure 2 As shown, the inner air outlet 112, the first outer air outlet 113 and the second outer air outlet 1212 are arranged in sequence from the end of the fan to the middle, so that when the fan is hung on the user's neck for use, the blowing area of ​​the fan in the length direction (front and back sides of the user) is expanded, thereby improving the heat dissipation efficiency of the fan.

[0052] In some embodiments, the housing 1 may be an integrally formed component, and the air inlet 111, the inner air outlet 112, the first outer air outlet 113, and the second outer air outlet 1212 may be through holes respectively opened on the housing 1 and connected to the accommodation space 116. In other embodiments, the housing 1 may include an inner housing 11 and an outer housing 13, wherein the air inlet 111, the inner air outlet 112, and the first outer air outlet 113 are opened in the inner housing 11; the outer housing 13 is connected to a side of the side portion 115 of the inner housing 11 away from the inner portion 114, and cooperates with the inner housing 11 to form the accommodation space 116; there is a gap between the inner housing 11 and the outer housing 13 to form the second outer air outlet 1212.

[0053] In other embodiments, the housing 1 includes an inner housing 11, a middle piece 12 and an outer housing 13, the middle piece 12 is connected between the inner housing 11 and the outer housing 13, and the middle piece 12 has a notch 1211, and two second outer air outlets 1212 are formed at opposite ends of the notch 1211. In other words, the fan may include two second outer air outlets 1212 that are arranged oppositely and connected.

[0054] For example, Figure 2 As shown, the inner part 114 and the side part 115 can both be used as a part of the inner shell 11, so that the air inlet 111, the inner air outlet 112 and the first outer air outlet 113 are opened in the inner shell 11. The middle piece 12 can be connected (for example, snap-fitted) with the inner shell 11 to form a receiving space 116. The outer shell 13 can be attached to the side of the middle piece 12 away from the inner shell 11 as a decorative piece, and the outer edge of the middle piece 12 is exposed, wherein the outer shell 13 (or the middle piece 12) can be used as the outer side of the shell 1 opposite to the inner part 114, and connected to one end of the side part 115 away from the inner part 114. The notch 1211 on the middle piece 12 can be covered by the inner shell 11 and the outer shell 13, so that only the two ports of the notch 1211 along the width direction of the fan can be used as the second outer air outlet 1212 to blow air outward.

[0055] like Figure 2 and Figure 3 As shown, the fan may further include a refrigeration element 3 and a heat conducting element 4. The refrigeration element 3 is located in the accommodation space 116, and the cold end of the refrigeration element 3 is at least partially exposed to the inner portion 114; the heat conducting element 4 is connected to the inner portion 114 and contacts the portion of the refrigeration element 3 exposed to the inner portion 114.

[0056] In some embodiments, the refrigeration element 3 may be a semiconductor refrigeration element. The semiconductor refrigeration element is usually a sheet-like element and can be energized. When current passes through, heat transfer occurs between the two ends, so that the semiconductor refrigeration element may include a cold end for cooling the surrounding environment and a hot end for heat dissipation, and the cold end is opposite to the hot end.

[0057] The inner side 114 of the housing 1 may be provided with an escape opening 117, and after the refrigeration component 3 is accommodated in the accommodation space 116, the cold end of the refrigeration component 3 may be exposed from the escape opening 117. The size of the escape opening 117 may be substantially the same as that of the refrigeration component 3, or may be slightly larger or smaller than that of the refrigeration component 3.

[0058] The inner side portion 114 of the housing 1 may be partially recessed outward, for example, the middle portion of the inner side portion 114 may be recessed outward, so that the two ends of the inner side portion 114 may be raised relative to the middle portion to form an installation space in the middle portion. An escape opening 117 for exposing the refrigeration component 3 may be provided in the middle portion of the inner side portion 114, so that after the heat conducting component 4 is installed in the installation space, the heat conducting component 4 may be attached to the middle portion of the inner side portion 114 and contact the portion of the refrigeration component 3 exposed in the escape opening 117. The heat conducting component 4 may be made of a metal material with good thermal conductivity and light weight, such as aluminum; and the housing 1 may be basically made of a plastic material to reduce the overall weight and cost of the fan. When the fan is hung on the user's neck for use, the heat conducting component 4 may surround and adhere to the user's neck to quickly cool the user's neck over a large area.

[0059] In addition, after the heat conducting member 4 is installed in the installation space, the heat conducting member 4 can smoothly transition with the end of the inner portion 114 away from the air inlet 111, and there is a height difference in the thickness direction between the end where the air inlet 111 is located and the heat conducting member 4. The inner air outlet 112 can be opened in the portion of the inner portion 114 corresponding to the height difference. Figure 1 and Figure 2 As shown, the heat conducting component 4 may be located at the air outlet side of the inner air outlet 112 so that the wind blown out of the inner air outlet 112 can accelerate the flow of low-temperature air near the heat conducting component 4, thereby improving the heat dissipation efficiency of the fan.

[0060] In some embodiments, the second outer air outlet 1212 may be disposed corresponding to the refrigeration component 3 to also have the function of dissipating heat from the hot end of the refrigeration component 3 .

[0061] In order to further improve the heat dissipation efficiency of the hot end of the refrigeration element 3, as Figure 3 and Figure 4 As shown, the fan further includes a heat sink 5 ; the heat sink 5 is connected to the hot end of the refrigeration element 3 , and the heat sink 5 is partially exposed from the second outer air outlet 1212 .

[0062] In some embodiments, Figure 4 As shown, the heat sink 5 may be located between the gaps 1211 forming the two second outer air outlets 1212 .

[0063] The heat sink 5 can be made of a metal material with good thermal conductivity and light weight, such as aluminum. The heat sink 5 can also be a component with a grid, including a mounting portion and a grid portion connected to each other. The grid can be used as a heat sink fin to increase the heat dissipation area of ​​the heat sink 5, thereby improving the heat dissipation efficiency. The cooling element 3 can be attached and fixed to the side of the mounting portion away from the grid portion.

[0064] It is understandable that since the power of the semiconductor refrigeration component is usually not large, the heat generated by its hot end is not high. When the wind passes through the heat sink 5 and is blown out from the two second outer air outlets 1212, the temperature change is small, that is, the air outlet temperature of the two second outer air outlets 1212 is not much different from the temperature of the inner air outlet 112 and the first outer air outlet 113, which will not affect the cooling of the user's neck and head.

[0065] In some embodiments, the notch 1211 can be set to be a trapezoid, and the shape of the heat sink 5 can match the shape of the notch 1211, so that the sizes of the two second outer outlets formed by the opposite ends of the notch 1211 are different. The second outer notch 1211 formed by the top of the trapezoid with a smaller size can be located in the direction toward the user's head (upward), and the second outer notch 1211 formed by the bottom of the trapezoid with a larger size can be located away from the user's head (downward).

[0066] In order to maximize the air output of each air outlet and ensure that the wind blown out by the fan assembly 2 is basically blown out through the inner air outlet 112, the first outer air outlet 113 and the second outer air outlet 1212, the end of the second outer air outlet 1212 farthest from the fan assembly 2 can be isolated from the accommodating space 116 to prevent the wind blown out by the fan assembly 2 from continuing to flow to the middle part of the fan where no air outlet is set (for example, the part of the left air outlet mechanism 100 close to the connecting mechanism 300) after passing through the inner air outlet 112, the first outer air outlet 113 and the second outer air outlet 1212.

[0067] like Figure 4 and Figure 5As shown, the middle piece 12 includes a main body 121 and a circumferential baffle 122 with a avoidance opening 1221, and a notch 1211 is opened in the main body 121; the circumferential baffle 122 is connected to the main body 121 and extends in a direction close to the inner shell 11 to connect with the inner shell 11; the avoidance opening 1221 faces the fan assembly 2, and the circumferential baffle 122 is arranged around the first side, the second side and the third side of the notch 1211, wherein the first side is a side of the notch 1211 away from the fan assembly 2, the second side and the third side are respectively adjacent to the first side, and the second side and the third side are opposite; the heat sink 5 is limited in the space enclosed by the circumferential baffle 122.

[0068] In some embodiments, Figure 5 As shown, the circumferential baffle 122 can be a three-sided structure, including a first baffle 1222, a second baffle 1223 and a third baffle 1224, wherein the first baffle 1222 is used to isolate the first side of the gap 1211 away from the fan assembly 2; the second baffle 1223 and the third baffle 1224 are respectively connected to the opposite ends of the first baffle 1222, respectively used to isolate the second side and the third side of the gap 1211. The heat sink 5 can be embedded in the circumferential baffle 122, and the avoidance opening 1221 is located on the side opposite to the first baffle 1222 to expose the heat sink 5.

[0069] like Figure 6 and Figure 7 As shown, the fan assembly 2 includes a fan 21 and a shroud 22, wherein the fan 21 is located inside the shroud 22; the shroud 22 is provided with a first opening 221, a second opening 222, a third opening 223, and a fourth opening 224, wherein the opening direction of the first opening 221 is toward the air inlet 111 and is connected to the air inlet 111, the opening direction of the second opening 222 is toward the inner air outlet 112 and is connected to the inner air outlet 112, the opening direction of the third opening 223 is toward the first outer air outlet 113 and is connected to the first outer air outlet 113, and the opening direction of the fourth opening 224 is toward the avoidance opening 1221 and is connected to the avoidance opening 1221. In the fan provided in the embodiment of the present application, the shroud 22 can be used to limit the flow path of the airflow blown out by the fan 21 to avoid the airflow from diffusing to the surroundings and causing losses, thereby affecting the air volume of each air outlet.

[0070] In some embodiments, the air deflector 22 may include an upper shell and a lower shell that cooperate with each other, and a circular fan space and a long strip of air duct may be formed between the upper shell and the lower shell. The fan 21 may be located in the fan space, and the fan 21 may draw air from the external environment through the first opening 221 and the air inlet 111 that are connected, and blow air into the air duct, so as to blow out through the second opening 222 opened on the air duct wall and the inner air outlet 112 connected thereto, and blow out through the third opening 223 opened on the air duct wall and the first outer air outlet 113 connected thereto, and also blow to the heat sink 5 through the fourth opening 224 and the avoidance port 1221 connected thereto, so as to take away the heat on the heat sink 5 and blow it out from the two second outer air outlets 1212. Since the circumferential baffle 122 is connected between the main body 121 of the middle piece 12 and the inner shell 11, the circumferential baffle 122 can prevent the airflow from continuing to flow along the length direction of the fan after passing through the notch 1211, so that the airflow can only be blown out from the second outer air outlet 1212, thereby increasing the air output of the second outer air outlet 1212.

[0071] In some embodiments, the inner air outlet 112 and the first outer air outlet 113 can be arranged adjacent to the fan 21 so as to be located between the fan 21 and the heat sink 5, thereby reducing the air outlet stroke corresponding to the inner air outlet 112 and the first outer air outlet 113 (i.e., the distance from the fan assembly 2 to each air outlet), thereby increasing the air outlet volume of the inner air outlet 112 and the first outer air outlet 113.

[0072] In some embodiments, the fan assembly 2 may further include a circuit board 23, which is electrically connected to the fan 21 and is used to control the opening or closing of the fan 21. The middle piece 12 may be used to install and support the circuit board 23.
