Abstract
The utility model provides a 0-360 degrees adjustable oscillating electric fan which uses a computer parallel port to control the rotation of a stepping motor and mainly aims to solve the problem that the oscillating angle and the oscillating speed of the prior table type electric fans and floor-standing electric fans cannot be adjusted freely by users. In order to solve the technical problems, the utility model adopts the technical scheme that computer parallel interface pins 2 and 3 are connected to the CP minus end and the CW minus end of a stepping motor driver, the A plus end, the A minus end, the B plus end and the B minus end of the stepping motor driver are connected with the stepping motor respectively, a driving gear of the stepping motor is meshed with a transmission gear on a support bar, and with the rotation of the driving gear driving the transmission gear to rotate, the transmission gear drives the support bar to rotate, and a fan motor fixed on the support bar follows suit. The utility model provides the users with a humanized control method for freely adjusting the oscillating time, angle and speed of the electric fan on the screen of a computer, which to a greater extent meets different demands of different users under different circumstances.
Description
Technical field
This electric fan is the rotation that utilizes computer printer port control step motor.
Background technique
Shaking the head of table fan and pedestal fan drives with common electric machine at present, and the user was non-adjustable after the angle of shaking the head, the speed of shaking the head were dispatched from the factory.
Summary of the invention
In order to make the panning angle of table fan and pedestal fan, the speed of shaking the head is regulated arbitrarily according to different needs by the user, the utility model provides a kind of 0 ° to 360 ° adjustable electric fan of shaking the head, this model utility solves the technological scheme that its technical problem adopts: with computer parallel interface pin 2,3 respectively with the CP-of stepper motor driver, the CW-end links to each other, the A+ of stepper motor driver, A-, B+, the B-end links to each other with stepper motor respectively, the actuation gear of stepper motor and the driving gear on the supporting rod match, the rotation of the rotating band nutating gear of actuation gear, the rotation of driving gear drives supporting rod and rotates, and the fan electromotor that is fixed on the supporting rod also rotates thereupon.
The beneficial effects of the utility model are:
1, the user can set time, angle and the speed of electric fan oscillating arbitrarily on the screen of computer, and the control mode of this hommization has satisfied the different demands of different user under varying environment largely, is that other controller is difficult to accomplish.
2, that utilize to eliminate or existing computer has reduced a large amount of Peripheral Controller as the core control part of this device, has saved spending, has reduced investment, has made full use of existing equipment.
Description of drawings
Accompanying drawing is 0 ° of schematic diagram to 360 ° of adjustable electric fans of shaking the head, and is (1) computer parallel interface among the figure, (2) stepper motor driver, (3) electric fan base, (4) supporting rod, (5) driving gear, (6) fan electromotor, (7) stepper motor, (8) actuation gear.
Embodiment

2, write control program, computer parallel interface (1) pin 3 is changed to " 1 ", hold the rotation of stepper motor clockwise direction to CP-from the 2 output digital pulses of computer parallel interface (1) pin.When pin 3 was changed to " 0 ", stepper motor counterclockwise rotated.When pin 2 was changed to " 0 ", stepper motor stopped the rotation.The frequency that changes pin 2 output digital pulses has just changed the speed of stepper motor rotation.Read the real-time clock of computer, can set electric fan and when shake the head and when do not shake the head.
3, selecting step angle for use is 1.8 ° stepper motor, and several 10 as input pulse on screen, then electric fan is shaken the head in 0 ° to 18 ° scope, and maximum number of pulses is less than 200.
4, this control program is used the C language compilation under WINDOWS 98 operation systems.
Claims (4)
