Abstract:
A neck-hanging fan (30), comprising an arc-shaped shell (10) and at least four fan assemblies (20). The arc-shaped shell (10) can be worn on the neck of a human body. The arc-shaped shell (10) has a first part (11) and a second part (12). The first part (11) and the second part (12) are respectively located at two sides of the neck of the human body. The first part (11) and the second part (12) each comprise a sidewall structure enclosing an accommodating cavity (105). The first part (11) and the second part (12) each have an air inlet (106) and an air outlet (107) communicated with the accommodating cavity (105). At least one partition board (13) is further provided in the accommodating cavity (105). The accommodating cavity (105) is divided by the at least one partition board (13) into at least two accommodating portions (105a, 105b) that are sequentially arranged in the extension direction of the arc-shaped shell (10). Each accommodating portion (105a, 105b) corresponds to a part of the air inlet (106) and a part of the air outlet (107). Each fan assembly (20) is located in the corresponding accommodating portion (105a, 105b). Each fan assembly (20) is used for guiding air of the air inlet (106) corresponding to the accommodating portion (105a, 105b) to the air outlet (107) corresponding to the accommodating portion (105a, 105b) to be blown out. There is a plurality of air outlets (107), and the plurality of air outlets (107) are arranged in the extension direction of the arc-shaped shell (10). The sizes, shapes and/or the space between two adjacent air outlets (107) among the plurality of air outlets (107) gradually change in the extension direction of the arc-shaped shell (10) in a preset mode.
