Abstract
Description
technical field
[0001] The invention relates to a 360-degree steering double-frequency conversion speed-regulating electric fan, which can remarkably circulate indoor air, and is a new type of household electrical appliance. Background technique
[0002] Air-conditioning heating and cooling equipment can effectively improve the indoor temperature, but people often find that after turning on the air-conditioning heating and cooling equipment indoors, the temperature difference between the ground and the roof is often very large, which makes people feel uncomfortable, especially those who suffer from air-conditioning syndrome The crowd is not suitable for blowing air conditioners. On the other hand, due to poor indoor air circulation, if clothes are dried in the room, mold or peculiar smell will also be produced in the closed room. How to effectively promote the alternation of indoor airflow, solve the problem of indoor air stagnation, and realize the balance of indoor temper...

Embodiment Construction
[0086] The present invention as Figure 1 to Figure 15 shown. The specific embodiment of the present invention is illustrated below in conjunction with accompanying drawing:
[0087] A 360-degree steering double frequency conversion speed regulating electric fan, consisting of fan cover 1, fan seat 2, base shell 3, base cover plate 4, power cord 5, fan blade 6, hand screw 7, permanent magnet brushless DC motor 8. Composed of PCB board 9, high-torque permanent magnet DC motor 10, rotating ball column 11, and bearing 12, it is characterized in that:
[0088] The 360-degree turning dual-frequency conversion speed-regulating electric fan is a double-motor drive structure, the air supply part is driven by a permanent magnet DC brushless motor 8, and the 360-degree turning part of the fan seat is driven by a high-torque permanent magnet DC motor 10. The control is realized by the circuit on the PCB board 9, and the dual-core single-chip computer 91 can control the permanent magnet...
