DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments.

[0025] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0026] like Figures 1 to 5 As shown, this embodiment provides a neck-hanging fan, comprising a housing 1, a fan assembly 2 and a baffle. The housing 1 is mounted on the neck of a human body, and the housing 1 is formed with an air inlet 11, a receiving cavity 12, an air duct 13 and an air outlet 14 which are connected in sequence; the fan assembly 2 is received in the receiving cavity 12, and is used to blow the air from the air inlet 11 through the air duct 13 and out of the air outlet 14; the baffle is provided in the air duct 13, and is used to adjust the air outlet angle; wherein the baffle comprises: one or more first baffles 31 extending to the air outlet 14 at one end, and one or more second baffles 32 at a predetermined distance from the air outlet 14.

[0027] The wind outlet angle is changed by the baffle, so that the user can feel the wind when using the neck hanging fan, thereby realizing the user's cooling experience. In addition, since the second baffle 32 is at a predetermined distance from the air outlet 14, the air outlet range of the adjacent air outlet 14 is larger, and the air outlet effect can be improved. After testing, the first baffle 31 and the second baffle 32 are arranged in the air duct 13, so that the wind can be blown more toward the user's face or head, thereby improving the user experience.

[0028] like Figures 1 to 3 As shown, the air outlet 14 usually passes through the longitudinal front side of the two clamping arms 15 of the housing 1 and is connected to the air duct 13, and is basically arranged along the air duct 13. The width of the end of the air duct 13 away from the accommodating chamber 12 is narrower, which is more conducive to gathering wind, so that the air outlet 14 can be more uniform. The fan assembly 2 is located at the neck, and the fan assembly 2 is located at the ends of the two clamping arms 15. The two clamping arms 15 can be rotatably connected by a rotating connector for easy storage; or the two clamping arms 15 can be telescopically connected to each other to adapt to multiple user groups.

[0029] Further, such as Figure 3 As shown, the first baffle 31 is bent upward at one end of the air outlet 14, and the second baffle 32 is bent downward near the air outlet 14. That is, the air outlet formed between the first baffle 31 and the second baffle 32 above it is a more concentrated inverted figure eight shape, and the air outlet formed between the first baffle 31 and the second baffle 32 below it is a more diffuse figure eight shape. The second baffle 32 can be arranged at a predetermined position to enhance the air outlet effect, so that more wind is blown to the face or head of the user.

[0030] Further, such as Figure 3 As shown, the first baffle 31 and the second baffle 32 are arranged at intervals, and a first channel is formed between the first baffle 31 and the second baffle 32 adjacent thereto below, and a second channel is formed between the first baffle 31 and the second baffle 32 adjacent thereto above. That is, the second baffle 32 is arranged between at least some of the adjacent first baffles 31, the first channel forms an eight-shaped shape, and the second channel forms an inverted eight-shaped shape, and the wind direction is further changed by the second baffle 32, thereby increasing the wind outlet range of the air outlet 14 between the adjacent first baffles 31 and enhancing the wind outlet effect.

[0031] Further, such as Figure 3 As shown, a vertical projection of at least one of the first baffles 31 is at least partially located on the second baffle 32 , that is, in the longitudinal direction, the second baffle 32 protrudes from at least one of the first baffles 31 , further changing the wind direction and wind speed in the air duct 13 .

[0032] Further, such as Figure 3As shown, the angle formed by the first baffle 31 is smaller than the angle formed by the second baffle 32, so that the air outlet range of the adjacent air outlet 14 is larger. Preferably, the angle formed by the second baffle 32 is greater than 145° and less than 175°.

[0033] Further, such as Figure 2-3 As shown, the neck-hanging fan also includes a partition 4, which separates the interconnected accommodating chamber 12 and the air duct 13 from other spaces in the housing 1, and the width of the air duct 13 away from the end of the accommodating chamber 12 is smaller than the width of the air duct 13 close to the end of the accommodating chamber 12, so as to reserve space for accommodating the battery 6. In this embodiment, batteries 6 are accommodated in both clamping arms 15, and the two fan assemblies 2 located at the neck can operate simultaneously or separately. Preferably, the partition 4 has a bending portion 41, and the second baffle 32 is provided between the bending portion 41 and the first baffle 31, that is, the air outlet formed between the bending portion 41 and the second baffle 32 is a more concentrated inverted figure eight shape, thereby enhancing the air outlet effect.

[0034] Further, such as Figure 1 As shown, the width of the air duct 13 on the side of the air outlet 14 is smaller than the width of the air duct 13 on the side away from the air outlet 14, so as to achieve the effect of gathering wind, thereby enhancing the air outlet effect.

[0035] Further, such as Figure 1 As shown, the neck hanging fan also includes a neck support 5 installed on the side of the housing 1 facing the human neck, the neck support 5 is made of silicone material, and the neck support 5 is arranged corresponding to the accommodating cavity 12, as shown in FIG. Figure 4-5 As shown, the housing 1 includes a first side wall 16 facing the human neck and a second side wall 17 facing away from the human neck, the air inlet 11 includes a first air inlet 111 located on the first side wall 16 and a second air inlet 112 located on the second side wall 17, and there is a gap between at least part of the neck support 5 and the first air inlet 111. The neck support 5 is provided to support the back neck area of ​​the human body so that it will not hurt the person and can be better attached to the human neck; and the neck support 5 can form a gap between the housing 1 and the back neck of the human body, thereby reducing the contact area between the housing 1 and the human neck, and improving the cooling effect of the neck hanging fan.

[0036] Further, such as Figure 4 and Figure 5 As shown, at least one third air inlet 113 is provided at the connection between the first side wall 16 and the second side wall 17. Providing the third air inlet 113 can reduce noise to a certain extent.

[0037] The above are only preferred embodiments of the present invention. The protection scope of the present invention shall be based on the scope defined by the claims. Several improvements and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall also be regarded as the protection scope of the present invention.
