[0031] Please refer to Figures 1 to 3 As shown, it shows the specific structure of a preferred embodiment of the utility model, which includes a main body 10 and a fan assembly 20.

[0032] The body 10 includes a first body 11 and a second body 12 connected together. An air passage 101 for air circulation is provided in the body 10, and the air passage 101 connects the interior of the first body 11 and the interior of the second body 12. The second body 12 is located outside the first body 11 and a hanging groove 102 is formed between the second body 11 and the first body 11, so that it can be hung on the collar of the user's back. An air outlet 103 connected to the air passage 101 is provided at the lower end of the first body 11, and an air inlet 104 connected to the air passage 101 is provided at the outer side of the second body 12. The extending direction of the first body 11 and the second body 12 is the up-down direction, one end of the first body 11 connected to the second body 12 is the upper end, and the other end is the lower end, and the opening direction of the hanging groove 102 in the up-down direction is downward. In this embodiment, the hanging groove 102 is in an inverted U shape, and in other embodiments, it can also be in an inverted V shape or other shapes.

[0033] In this embodiment, the first body 11 and the second body 12 are connected by an elastic part 13, and the elastic part 13 is used to facilitate the clamping between the first body 11 and the second body 12. The setting of the elastic part 13 makes it more convenient to hang and remove the body 10 on the collar. The elastic part 13 is made of silicone material, which makes it deformable so that it is convenient for users to hang on or remove clothes. Similarly, a rotating shaft can also be set in the silicone so that the first body 11 and the second body 12 can be rotated and adjusted.

[0034] Furthermore, the air inlet 104 includes a first air inlet 104a and a second air inlet 104b, and the first air inlet 104a is opened on the outer wall of the second main body 12 away from the hanging groove 102; the first air inlet 104a is extended laterally, and a plurality of the first air inlet 104a are arranged at intervals along the extension direction of the second main body 12; the direction perpendicular to the extension direction of the first main body 11 and the second main body 12 is the transverse direction, and the first air inlet 104a can also be extended longitudinally or in other extension methods. Similarly, the first air inlet 104a can be rectangular, circular or other suitable shapes, without limitation. A second air inlet 104b is provided on the side wall of the second main body 12 adjacent to the hanging groove 102, and the second air inlet 104b is arranged on the adjacent side wall of the side wall where the first air inlet 104a is located. The arrangement of the first air inlet 104a and the second air inlet 104b allows air to be taken in from the outer side wall of the second main body 12 and other adjacent side walls at the same time, thereby ensuring a sufficient amount of air entering the air intake duct 101; the first air inlet 104a arranged on the outer side wall and the second air inlet 104b arranged on the adjacent side wall can prevent the first air inlet 104a and the second air inlet 104b from being blocked by clothes during use. The side wall of the first main body 11 away from the hanging groove 102 is recessed inward (i.e. recessed toward the inside of the main body) to have a first arc portion 111. The first arc portion 111 is used to prevent the fan from being clamped at the collar of the back, thereby preventing the first main body 11 from failing to fit the back and causing discomfort. The first arc portion 111 is recessed toward the inside of the first main body 11 and has a certain curvature, so that it can fit the user's back.

[0035] In one embodiment, a metal plate 14 is disposed on the outer surface of the side wall of the first body 11 away from the hanging groove 102, and the metal plate 14 is recessed with a second arc portion 141 toward the first body 11, and the second arc portion 141 is consistent with the first arc portion 111, and is used to fit the human body. The metal plate 14 is used to provide contact cooling and cooling for the user through the low temperature characteristic of the metal plate 14 itself, further improving its cooling effect, and at the same time, the second arc portion 141 is provided so that it can fit the back of the user, preventing the metal plate 14 from not being able to completely fit the back of the user and causing discomfort.

[0036] Further, the air channel 101 is a double-layer structure, for example, including a first layer close to the hanging groove 102 and a second layer away from the hanging groove 102, the first layer is connected to the air inlet 104, the second layer is connected to the air outlet 103, and the fan assembly 20 is a centrifugal fan assembly and is arranged in the second layer, so that when the fan assembly rotates, airflow is generated and blown out from the air outlet 103 to the user. By dividing the air channel 101 into two layers, the airflow enters the fan assembly 20 of the second layer through the first layer, which facilitates the fan assembly 20 to take in air axially and then discharge air radially.

[0037] More specifically, a partition 105 is provided in the body 10, and the partition 105 separates the air passage 101 into the first layer and the second layer. A communication port 106 is provided on the partition 105 at a position corresponding to the air inlet side of the fan assembly 20. The fan assembly 20 is located in the second layer and communicates with the first layer through the communication port 106, thereby communicating with the air inlet 104, and the fan assembly 20 takes in air through the communication port. A volute 15 is also provided in the body 10, and the fan assembly 20 is located in the volute 15. The volute 15 is arranged around the fan assembly 20, and the volute 15 has an air outlet side that communicates with the air outlet 103, so as to guide the fan assembly 20 to rotate to generate airflow that is blown out from the air outlet side to the air outlet and blown out of the body 10.

[0038] Furthermore, one end of the first body 11 is connected to the second body 12. When the body 10 is hung on the collar, the other end of the first body 11 extends into the inside of the clothes, and an air outlet 103 is provided at the end to ensure that the air outlet direction is inside the clothes and blow the air flow into the clothes.

[0039] The fan assembly 20 is arranged on the main body 10 and located in the air passage 101. A battery (not shown) electrically connected to the fan assembly 20 is also provided in the main body 10. The fan assembly 20 is used to suck air from the air inlet 104 into the air passage 101 and send it out from the air outlet 103. In conjunction with the setting of the hanging groove 102, the fan assembly 20 can allow external air to enter from the air inlet 104, enter the first main body 11 along the air passage 101, and finally send it out from the air outlet 103, thereby realizing the blowing and heat dissipation process inside the clothes; in this embodiment, the fan assembly is arranged in the volute 15, and the fan assembly 20 includes a centrifugal fan blade 21 and a motor (not shown in the figure) for driving the centrifugal fan blade 21 to rotate, and the centrifugal fan 21 is located beside the air outlet 103.

[0040] The working principle of this embodiment is described in detail as follows:

[0041] Taking the use of the fan hung on the collar of the user's back as an example, when using it, first open the first body 11 and the second body 12 on the main body 10, then hang it on the collar of the user's back, and clamp the first body 11 and the second body 12 through the elastic part 13, then turn on the power switch to make the fan assembly 20 work. At this time, the fan assembly 20 will suck the external air from the first air inlet 104a and the second air inlet 104b into the air duct 101, and blow the air out through the air outlet 103, thereby realizing the blowing and cooling process inside the clothes.

[0042] The design focus of the utility model is that: the main body includes a first main body and a second main body connected together, the second main body is located on the outside of the first main body and is surrounded by the first main body to form a hanging groove, so that the main body can be hung on the collar of the user's back through the hanging groove, and an air outlet connected to the airway is opened at the lower end of the first main body, an air inlet connected to the airway is opened on the outside of the second main body, and a fan assembly is used to suck air from the air inlet into the airway and send it out from the air outlet, so that after the external air is sucked into the main body through the fan assembly, the air is blown into the inside of the clothes through the air outlet, thereby achieving blowing and cooling of the inside of the clothes. Compared with the blowing method to the neck and head, the cooling effect is better, can meet the user's cooling needs for the parts covered by the clothes, and the user's experience is also better.
