Embodiment approach

[0008] figure 1 It is a schematic diagram of the overall structure of the safety electric fan of the present invention. In the figure, the panel 10 of the electric fan is provided with: a gravity sensor 11, which is connected to the internal power switch of the electric fan; a knob box 20, which is provided with a wind speed adjustment knob inside and lighting lamps; wind speed display screen 30, which receives the wind speed data of the fan motor.

[0009] like figure 1 As shown, the panel of the safety electric fan in the figure is provided with: a gravity sensor, which is connected to the internal power switch of the electric fan. When the electric fan falls down, the gravity sensor sends a shutdown signal to the power switch to cut off the electric fan The power supply improves the safety of the electric fan. At the same time, the wind speed display screen on the panel can receive and display the wind speed data of the fan motor so as to know the wind speed of the electr...

Abstract

The invention discloses an electric safety fan. The electric safety fan is characterized in that a panel of the electric fan is provided with a gravity sensor and a knob box, wherein the gravity sensor is connected with an internal power switch of the electric fan; when the electric fan falls down, the gravity sensor transmits a switching-off signal to the power switch so as to cut off the power of the electric fan, so that the safety of the electric fan is improved; the knob box is internally provided with an air speed adjusting knob and an illuminating lamp; and simultaneously an air speed display screen on the panel can receive and display air speed data of a motor of the fan so as to be convenient for a user to know the air speed condition of the electric fan at any time.

Description

technical field [0001] The invention relates to a safety electric fan, in particular to a safety electric fan which can automatically cut off the power supply. Background technique [0002] When the weather is hot, people use the electric fan for cooling. When it is running, the blades of the electric fan rotate at a high speed under the drive of the motor to create cool wind. Sometimes people accidentally knock down the floor-standing electric fan, and its motor is still in a charged working state and is thrown to the ground, which may cause a short circuit and even cause a fire. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric fan, more specifically, to provide a safety electric fan that can automatically cut off the power supply. [0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a safety electric fan, which is characterized in that ...
