Claims24
A fan module for a neck fan, comprising:
- a fan housing;
- a connecting piece, arranged inside the fan housing and provided with a fan channel;
- and
- a fan assembly, sleeved on the connecting piece and connected to the connecting piece through a rotating shaft.
A portable fan based on a high-speed three-phase motor, comprising a control module, a drive module, and a high-speed three-phase motor, wherein a working voltage of the high-speed three-phase motor is 2 to 18 volts, and a working current of the high-speed three-phase motor is 0.1 to 10 amperes;
- the control module controls a rated rotating speed of the high-speed three-phase motor through the driving module based on the working voltage and the working current, so as to reduce high-speed noise of the high-speed three-phase motor and to control a wind speed to be within a preset wind speed range.
A neck fan, comprising a fan motor, a ventilation channel, and a first air inlet and a first air outlet connected to the ventilation channel, the fan motor is installed inside the ventilation channel and operates to form an airflow through the ventilation channel between the first air inlet and the first air outlet;
- at least two silencing devices are installed in the ventilation channel, with at least one silencing device located between the first air inlet and the fan motor, and at least another silencing device located between the fan motor and the first air outlet.
