Abstract
The utility model relates to a structure of a program-controlled electric fan with a touching induction chip, wherein, a program-controlled circuit board of the touching induction chip is arranged in an electric fan; after a touching signal of the electrostatic induction of the human body is input into the touching induction chip for information process by a touching induction end via a feedback circuit of a touching induction signal, a command is emitted to control the electric fan to realize various functions of breeze, light wind, strong wind and rotation stop. The utility model has the advantages of convenient operation, cost reduction, safe operation but no spark generation, reducing mechanical failures.
Description
The utility model relates to electric fan, particularly a kind of touch sensible chip program control type electric fan.
The switch of general electric fan, no matter piano keys type, push button all belong to mechanical type control, and shortcoming is that mechanical power switch equipment is complicated, volume is big, is out of order easily, the cost height, and in use can produce spark.
The purpose of this utility model provides a kind of touch sensible chip program control type electric fan, and not only volume is little, and cost is low, and is easy to operate, and in use can not produce spark, and rate of breakdown is low.
The purpose of this utility model is achieved in that
Inside at the electric fan mounting, touch sensible chip programme-controlled circuit plate is installed, and touch sensible chip programme-controlled circuit plate is made up of touch sensible end, step-down, rectification, eliminator, program control chip, touch sensible signal feedback circuit, SCR control motor circuit, motor, ac power supply live wire end, zero line side.
Working principle of the present utility model and circuit connecting relation are as follows:
After external AC power supply flows to live wire end, process step-down, rectification, eliminator to the 220V Ac, become the direct current of 6.2V, flow to program control chip, simultaneously, the 220V Ac also directly flows to touch sensible signal feedback circuit and motor, and forms the loop with zero line side.
When the insulation crust of human body touch electric fan mounting, input end (1), (2), (3), (4) of program control chip are imported touch signal in the electrostatic induction of human body through the touch sensible signal feedback circuit by the inner touch sensible end of mounting, through after the information processing, send instruction from output terminal (5), (6), (7), (8), make the SCR control motor circuit according to instruction, the size of the electric current of control motor or disconnection realize gentle breeze, light breeze, high wind and the various functions that stop operating thereby reach the control electric fan.
Owing to adopt the utility model, replace the various functions of mechanical switch control electric fan with touch sensible chip programme-controlled circuit, not only easy to use, reduce cost, and also handling safety, can not produce spark, reduce mechanical failure.
With the enforcement side, further describe structure of the present utility model in conjunction with the accompanying drawings.
Accompanying drawing 1 is the utility model circuit theory diagrams.
Accompanying drawing 2 is that the utility model uses reference drawing.
Among the figure: the 1, the 2,3, the 4th, the input end of program control chip; 5, the 6,7, the 8th, the output terminal of program control chip; 10, touch sensible chip journey connection circuit plate; 11, touch sensible end; 12, ac power supply live wire end; 13, zero line side; 14, motor; 15, SCR control motor circuit; 16, step-down, rectification, eliminator, 18, program control chip; 19, touch sensible signal feedback circuit.
Embodiment:
Inside in electric fan mounting (9), touch sensible chip programme-controlled circuit plate (10) is installed, and touch sensible chip programme-controlled circuit plate (10) is made up of touch sensible end (11), step-down, rectification, eliminator (16), program control chip (18), touch sensible signal feedback circuit (19), SCR control motor circuit (15), motor (14), ac power supply live wire end (12), zero line side (13).
Working principle of the present utility model and circuit connecting relation be as shown in Figure 1:
After external AC power supply flows to live wire end (12), process step-down, rectification, eliminator (16) to the 220V Ac, the direct current that becomes 6.2V flows to program control chip (18), simultaneously, the 220V Ac also directly flows to touch sensible signal feedback circuit (19) and motor (14), and difference forms the loop with zero line side (13).
When the insulation crust of human body touch electric fan mounting (9), the electrostatic induction of the human body induction end (11) that is touched is imported input end (1), (2), (3), (4) of program control chip (18) to touch signal through touch sensible signal feedback circuit (19), through after the information processing, send instruction from output terminal (5), (6), (7), (8), make the size and the disconnection of the electric current of SCR control motor circuit (15) control motor (14), realize gentle breeze, light breeze, high wind and the various functions that stop operating thereby reach the control electric fan.
Claims (2)
