The invention discloses an electric fan, an electric fan swing control device and a swing control method. The electric fan swing control device comprises a first motor, a second motor and a controller, wherein the first motor is used for controlling the horizontal swing of the electric fan; the second motor is used for controlling the vertical swing of the electric fan; a first end and a second end of the controller are respectively connected with the first motor and the second motor, a first control signal is output by the first end, a second control signal is output by the second end, and the conducting time of the first control signal is different from that of the second control signal. Therefore, the electric fan is driven to vertically swing and horizontally swing for different time through the outputting of the first control signal and the second control signal with different conducting time, the swing moving trajectory of the electric fan continuously varies, large-range air blowing is realized, the air blowing region does not have a dead zone, and the user experience is improved.
Description
technical field [0001] The invention relates to the technical field of electrical appliances, in particular to an electric fan swing control device, an electric fan and an electric fan swing control method. Background technique [0002] With the continuous improvement of people's living standards, electric fans have become an indispensable part of people's lives. In addition to enjoying the coolness, people also put forward higher requirements on the functions of fans. The diversification and differentiation of functions have attracted consumers' attention. For example, fans of related technologies integrate functions such as humidification and mosquito repellent. [0003] In related technologies, a motor is usually used to control the swing of the electric fan, and most of the electric fans are controlled to swing according to a fixed swing trajectory. For example, the electric fan can be controlled to only swing left and right or up and down in a certain range. For anothe...
