Neck fan

A neck fan, configured to be worn around the neck of a user, and comprising:

• a neck fan main body, comprising two blowing main bodies respectively configured to be arranged on two sides of the neck of the user, wherein each blowing main body comprises a blowing housing;
• the blowing housing forms an accommodating cavity and is provided with at least one air inlet communicated to the accommodating cavity and at least one first air outlet communicated to the accommodating cavity;
• fan blade groups, arranged in the accommodating cavities, wherein each fan blade group comprises a boss, an annular base plate arranged on an outer side of the boss, a first centrifugal vane wheel arranged on the boss and comprising a plurality of first blades, and a second centrifugal vane wheel arranged on the base plate and comprising a plurality of second blades;
• the first centrifugal vane wheel and the second centrifugal vane wheel are arranged on a same side relative to the base plate, and the second centrifugal vane wheel is arranged around a periphery of the first centrifugal vane wheel;
• each blowing housing comprises a first side, a second side opposite to the first side, a third side adjacent to the first side and the second side, and a fourth side adjacent to the third side, the first side is an inner side for approaching the neck of a user, and the second side is an outer side arranged in a back-to-back manner with the inner side;
• the at least one air inlet is provided in the second side, and corresponds to the first centrifugal vane wheel and the second centrifugal vane wheel;
• the first side has no air inlet, so that the blowing housing is formed into a single-sided air inlet structure, thereby when the first side approaches the neck of the user, hairs of the user can be avoided from being entangled into the air inlet on the second side;
• and the first centrifugal vane wheel and the second centrifugal vane wheel are configured to guide air from the air inlet on a single side to the at least one first air outlet for blowing out;
• wherein a mounting hole is provided in one of the accommodating cavities, and a charging port component is provided at one of the blowing main bodies, the charging port component comprises a main circuit board and a charging port, the main circuit board is penetrated in the mounting hole in a direction substantially perpendicular to a surface of the one of the blowing main bodies, and the charging port is exposed at the surface of the one of the blowing main bodies;
• and
• wherein a first air duct is formed along a lengthwise direction of the one of the blowing main bodies;
• and the fan blade group is configured to suck air through the air inlet and convey the air to the first air outlet through the first air duct, and the mounting hole does not overlapped with the first air duct.
