[0031] Embodiment one

[0032] Reference Figures 1 to 10The neck-hung fan comprises a neck-hung main body 1, a first air guide cavity 2 in a straight cylinder shape is protruded at the lower end of the neck-hung main body 1, the first air guide cavity 2 comprises a first air inlet 22 arranged at the lower end of the neck-hung main body 1 and a first air outlet 23 arranged opposite to the first air inlet 22, the neck-hung main body 1 comprises an inner end 11 in contact with the user's neck, and the first air outlet 23 is arranged towards the inner end 11; a first fan assembly 3 is arranged in the first air guide cavity 2, and the first fan assembly 3 is used to drive airflow to blow from the first air inlet 22 to the inner end 11 through the first air outlet 23. Through the above structure, since the first air guide cavity 2 is in a straight cylinder shape, the neck-hung fan forms a straight blowing fan in the vertical direction, the first fan assembly 3 can drive airflow to blow from the first air inlet 22 to the inner end 11 through the first air outlet 23, greatly improving the blowing efficiency, and the user can directly feel the cool wind blowing directly to the neck when using the neck-hung fan, improving the overall performance of the fan. Moreover, since the first air guide cavity 2 is a straight cylinder cavity protruded from the neck-hung main body 1 in one piece, the design enhances the overall aesthetics and design sense of the product, and helps to improve the wearing comfort of the neck-hung fan, improving the overall quality and user experience of the product.

[0033] In the embodiment, the neck-hung fan is provided with a first air guide path 12 concave, the first air guide path 12 extends from the first air outlet 23 to the inner end 11, and the first fan assembly 3 drives airflow to blow out from the first air outlet 23 and blow to the inner end 11 along the first air guide path 12. Further, the inner end 11 is connected with a flexible first neck support part 111, the first neck support part 111 and the inner end 11 form a first air inlet gap 121, and the first fan assembly 3 drives airflow to blow out from the first air outlet 23 and blow to the first air inlet gap 121 along the first air guide path 12. Wherein, the first neck support part 111 can be a silica gel neck support part, a plastic neck support part, a rubber neck support part, etc. Through the above structure, when the airflow blows out from the first air outlet 23, under the guidance of the concave first air guide path 12, the airflow will blow to the inner end 11 along the first air guide path 12, and due to the first air inlet gap 121, the airflow can be blocked in the gap, so that the user wearing the neck-hung fan can more strongly feel the airflow of the inner end 11, enhancing the heat dissipation effect, and the flexible neck support part provides more comfortable support effect for the user, improving the user experience.

[0034] In the embodiment, the width of the first air guide path gradually decreases from the first air outlet towards the inner end; the width of the first air guide path ranges from 1-5cm; the length of the first air guide path ranges from 8-16cm; and the depth of the first air guide path ranges from 0-3cm.

[0035] In this embodiment, the neck hanging main body 1 is a U-shaped neck hanging main body 1, which comprises a first support 101, a second support 102 and a support connecting piece 103. The first support 101 and the second support 102 are detachably connected through the support connecting piece 103. The support connecting piece is a flexible support connecting piece 103. Specifically, the support connecting piece 103 can be a silica gel connecting piece, a plastic connecting piece, a rubber connecting piece or the like.

[0036] In this embodiment, the first support 101 comprises a first outer shell 1011 and a first inner shell 1012. The first air guide path 12 is arranged in the first inner shell 1012. The first inner shell 1012 is detachably connected with the first outer shell 1011 through buckles.

The second fan assembly 5 is used to drive the airflow from the second air inlet 42 to the second air outlet 43 and blow towards the inner end 11. Through the above structure, since the second air guide cavity 4 is a straight cylindrical shape, the neck hanging fan forms a straight blowing fan in the vertical direction, so that the second fan assembly 5 can drive the airflow from the second air inlet 42 to the second air outlet 43 and blow towards the inner end 11. This greatly improves the blowing efficiency, and the user can directly feel the cool wind when using the neck hanging fan, thereby improving the overall performance of the fan. Moreover, since the second air guide cavity 4 is a straight cylindrical cavity protruding from the neck hanging main body 1, this design enhances the overall aesthetics and design of the product, and helps to improve the wearing comfort of the neck hanging fan, thereby improving the overall quality and user experience of the product.
