[0002] At present, high-energy-consuming air conditioners and closed spaces make people susceptible to illness. Compared with air conditioners, low-energy and environmentally friendly electric fans allow air to circulate more easily, which is of great help to the human body. Traditional electric fans generally rotate left and right. function, but there is no up and down swing function. At the same time, the left and right swing angle cannot be adjusted, and the up and down swing angle cannot be adjusted. Sometimes the fan rotates at a large angle, and it takes a long time to blow to yourself. If only one person uses it Rotation or only a small angle of rotation is enough, so to a certain extent, it causes unnecessary waste of electric energy

The invention discloses a miniature multi-angle rotating fan. The miniature multi-angle rotating fan comprises a base. A left and right angle adjusting knob is arranged on the base, the left and right angle adjusting knob is connected with a fan left and right adjusting mechanism, the fan left and right adjusting mechanism is connected with a left and right control motor, an adjusting rod is fixed on the base, the adjusting rod is connected with a fan frame, a fan head is connected at the inner portion of the fan blade through a rotating shaft, an upper and lower swing switch is arranged on one side of the fan frame, the upper and lower swing switch is connected with an upper and lower control motor, the fan left and right adjusting mechanism is a crank slide bar structure, a slide bar of the crank slide bar structure is a threaded slide bar, the left and right adjusting knob is connected with the threaded slide bar of the crank slide bar structure, the upper and lower control motor is connected with an upper and lower swing angle adjusting rod, and an up stroke switch and a down stroke are arranged inside a circular arc formed by swinging the upper and lower swing angle adjusting rod. Circuits and machines are combined, then the miniature multi-angle rotating fan is simple in structure and easy to operate, stepless speed adjustment can be conducted on a swing angle, therefore, utilization efficiency is improved, and electric energy is saved.
Description
technical field [0001] The invention relates to a small fan, in particular to a small multi-angle rotating fan. Background technique [0002] At present, high-energy-consuming air conditioners and closed spaces make people susceptible to illness. Compared with air conditioners, low-energy and environmentally friendly electric fans allow air to circulate more easily, which is of great help to the human body. Traditional electric fans generally rotate left and right. function, but there is no up and down swing function. At the same time, the left and right swing angle cannot be adjusted, and the up and down swing angle cannot be adjusted. Sometimes the fan rotates at a large angle, and it takes a long time to blow to yourself. If only one person uses it Rotation or as long as a small angle of rotation is sufficient, thus causing unnecessary waste of electric energy to a certain extent. Contents of the invention [0003] The purpose of the present invention is to solve the a...
