[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0027] In this article, terms such as "upper, lower, inner, outer" are established based on the positional relationship shown in the drawings. Depending on the different drawings, the corresponding positional relationship may also change accordingly. Therefore, it cannot be understood as an absolute limitation of the protection scope; moreover, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0028] As Figures 1 to 2 shown, this embodiment provides a neck-mounted fan, which includes a housing 1 and a fan assembly 2. The housing 1 is mounted on the human neck. The housing 1 is formed with an air inlet 11, a receiving cavity 12, an air duct 13, and an air outlet 14 that are connected in sequence; the fan assembly 2 is received in the receiving cavity 12 and is used to blow air from the air inlet 11 through the air duct 13 and out of the air outlet 14; wherein, at least a part of the housing of the housing 1 at or near the air inlet 11 protrudes in a direction away from the fan assembly 2 to increase the distance between its inner wall surface and the fan assembly 2. The housing at the air inlet 11 protrudes relative to its adjacent housing, increasing the distance between the housing at the air inlet 11 and the fan assembly 2, thereby increasing the air-receiving space at the air inlet 11, that is, increasing the receiving cavity 12, so as to increase the air volume, improve the air outlet efficiency, improve the air outlet effect, and enhance the user's cooling experience. The outward protrusion means that the arc of the protruding housing has a greater curvature than that of its adjacent housing, and the housing at the protruding part of the housing 1 is smoothly transitioned with the adjacent housing, preferably formed by integral stamping.

[0029] Generally, the air inlet 11 is arranged adjacent to the accommodation cavity 12 and the fan assembly 2. The air outlet 14 penetrates 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 accommodation cavity 12 is narrower, which is more conducive to wind gathering, so that the air outlet of each part of the air outlet 14 is more uniform. The fan assembly 2 is located at the neck. The fan assembly 2 is located at the ends of the two clamping arms 15. The two clamping arms 15 can be rotatably connected through a rotating connector for easy storage; or the two clamping arms 15 can be telescopically connected to adapt to multiple user groups.

[0030] In one implementation scenario, as Figures 1 to 4 shown, the housing 1 includes a first housing 16 facing the human neck and a second housing 17 facing away from the human neck. The second housing 17 includes a main housing 171, a sub-housing 172 and a connecting housing 173 arranged in a stepped manner. The connecting housing 173 is connected to the main housing 171 and the sub-housing 172 on both sides respectively, and the connecting housing 173 is provided with the air inlet 11. The main housing 171 protrudes at least partially away from the fan assembly 2 at or near the air inlet 11, increasing the distance between the main housing 171 and the fan assembly 2 to increase the air volume and improve the air outlet efficiency. Preferably, the main housing 171 starts to protrude away from the fan assembly 2 from the edge closest to the air inlet 11. Referring to Figure 2 shown, that is, the main housing 171 corresponding to the fan assembly 2 protrudes at least partially vertically upward.

[0031] Furthermore, as Figure 2 shown, the maximum vertical distance of the air inlet 11 is greater than the vertical height of the connecting housing 173. Preferably, the edge of the air inlet 11 is the edge of the main housing 171 to increase the air inlet 11 and thus increase the air intake volume.

[0032] Furthermore, as Figure 3 shown, the air inlet 11 occupies more than one-half of the connecting housing 173 in the horizontal direction. Preferably, the maximum horizontal width of the air inlet 11 is greater than or equal to the horizontal width of the fan assembly 2 to increase the air inlet 11 and thus increase the air intake volume.

[0033] Furthermore, as Figure 3 shown, the connecting housing 173 is in an inclined shape or an arc shape, and the main housing 171 and the sub-housing 172 have a preset distance in the longitudinal direction, so that the air inlet 11 can be set larger.

[0034] Furthermore, at or near the air inlet 11, the auxiliary housing 172 protrudes at least partially away from the fan assembly 2, further increasing the air storage space. Preferably, the protruding positions of the main housing 171 and the auxiliary housing 172 are arranged in a staggered manner to prevent the auxiliary housing 172 from interfering with the air intake of the air inlet 11.

[0035] In another implementation scenario, as Figure 4 shown, the neck fan further includes a neck support 5 mounted on the first housing 16. The neck support 5 is made of silica gel material. The neck support 5 is provided corresponding to the accommodation cavity 12. The first housing 16 is provided with the air inlet 11 at the position where the neck support 5 is mounted, and there is a gap between at least a part of the neck support 5 and the air inlet 11. By providing the neck support 5 to support the back of the human neck area, it will not be uncomfortable and can better adhere to the human neck; and the neck support 5 can form a gap between the housing and the back of the human neck, thereby reducing the contact area between the housing and the human neck and improving the cooling effect of the neck fan. Preferably, the air inlet 11 correspondingly provided at the neck support 5 also protrudes away from the fan assembly 2.

[0036] In other implementation scenarios, as Figure 1 shown, more than one air inlet 11 is provided at the connection between the first housing 16 and the second housing 17 to reduce noise to a certain extent, and preferably the air inlet 11 also protrudes away from the fan assembly 2.

[0037] In one implementation scenario, 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 to achieve the effect of wind gathering, thereby enhancing the air outlet effect. As Figure 6 shown, the air duct 13 can be trapezoidal or can also be the shape in Figure 7 to increase the space of the air duct 13. Of course, it is preferably not limited to a specific shape to make the air duct 13 fit the housing 1 to the greatest extent.

[0038] Furthermore, as Figure 5As shown, a baffle for adjusting the air outlet angle is provided in the air duct 13; the baffle includes: more than one first baffle 31 with one end extending to the air outlet 14, and more than one second baffle 32 at a predetermined distance from the air outlet 14, and the bending directions of the first baffle 31 and the second baffle 32 are different. The second baffle 32 is at a predetermined distance from the air outlet 14, so that the air outlet range of the adjacent air outlet 14 is larger and the air outlet effect can be improved. The first baffle 31 and the second baffle 32 are arranged at intervals, that is, a more concentrated inverted V-shaped air outlet is formed between the first baffle 31 and the second baffle 32 above it, and a more diffused V-shaped air outlet is formed between the first baffle 31 and the second baffle 32 below it. The second baffle 32 can be set at a predetermined position to enhance the air outlet effect, so that more air blows towards the user's face or head.

[0039] In other implementation scenarios, such as Figure 5 As shown, at least a part of the vertical projection of at least one first baffle 31 is located on the second baffle 32, that is, in the longitudinal direction, the second baffle 32 protrudes longitudinally from at least one first baffle 31, further changing the wind direction and wind speed in the air duct 13.

[0040] In other implementation scenarios, such as Figure 5 As shown, the neck fan further includes a partition 4. The partition 4 separates the connected accommodation cavity 12 and the air duct 13 from other spaces in the housing 1. The width of the air duct 13 at the end far from the accommodation cavity 12 is smaller than the width of the air duct 13 at the end close to the accommodation cavity 12 to reserve space for accommodating the battery 6. In this embodiment, the battery 6 is 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 bent portion 41, and the second baffle 32 is arranged between the bent portion 41 and the first baffle 31, that is, a more concentrated inverted V-shaped air outlet is formed between the bent portion 41 and the second baffle 32 to enhance the air outlet effect.

[0041] The above is only the preferred implementation manner of the present invention. The protection scope of the present invention is subject to the scope defined by the claims. Several improvements and refinements made by those skilled in the art without departing from the spirit and scope of the present invention should also be regarded as the protection scope of the present invention.
