Abstract
The utility model relates to a fog brush device belongs to car fog brush field, including power, console switch K, control system, motor M and fog brush body, control system includes oscillation circuit and drive circuit again, has used the cmos pipe to replace traditional relay as drive switch among the drive circuit, has solved current fog brush system and has used the problem of noise occasionally, makes fog brush device quietly work, does not have the noise.
Description
Art
The utility model relates to automobile fog brush field, be specifically related to a kind of can the fog scraping brush device of quiet.
Background technology
During driving, due to the temperature difference inside and outside car, Windshield inwall can cover one deck water smoke, this can make chaufeur cannot distinguish the road conditions of outside, brings difficulty, even therefore traffic accident occurs to driving.Chaufeur generally all can have a piece of cloth, the fog be used for specially in wiping vehicle window, can make system for distraction of driver like this, and some safety misadventures occur.
Existing fog scraping brush system comprises power supply, control system, operating switch and fog scraping brush body mostly.But traditional fog scraping brush system has been mostly employing relay, and relay always sends the ticking sound when work, and in airtight compartment being affects concentrating of driver attention very much.Fog scraping brush is exactly interior rain brush, inside glass for vehicle window.
Summary of the invention
In order to overcome to have when existing fog scraping brush system uses the deficiency of noise, the utility model provide a kind of can the fog scraping brush device of quiet.
The technical solution of the utility model is: a kind of fog scraping brush device, and it comprises power supply, control system, motor M and fog scraping brush body; Power supply can be the original direct supply of automobile or battery supply or sun-generated electric power or other electric supply installations; Control system comprises operating switch K, oscillating circuit and driving circuit, and operating switch K is automatic reset switch; Oscillating circuit forms No. 3 mouth output signals by 555 chips; In driving circuit, the grid of cmos pipe connects No. 3 mouth received signals of oscillating circuit, be connected with operating switch K by resistance R3 simultaneously, the source electrode of cmos pipe is also connected with operating switch K, and the drain electrode of cmos pipe is connected with the anode of diode D3, and fog scraping brush body is connected with motor.
The utility model cmos pipe instead of traditional switch relay as driving switch, enables fog scraping brush device quiet, does not have noise.

Detailed description of the invention
See accompanying drawing, present embodiment is described.
Fog scraping brush device of the present utility model comprises power supply, control system, motor M and fog scraping brush body.Power supply can be the original direct supply of automobile, battery supply, sun-generated electric power or other electric supply installations, and its mouth exports as circuit is powered.Control system comprises operating switch K, oscillating circuit and driving circuit; One end of operating switch K is connected with power supply K mouth, and operating switch K is automatic reset switch, only has a stabilized conditions, and under this state, operating switch K does not contact with break back contact, only under the operation of operator, just contacts with break back contact.Oscillating circuit is formed by connecting by 555 chips, diode, resistance, electric capacity, tunable capacitor, No. 3 mouth output signals of oscillating circuit.Driving circuit is formed by connecting by resistance R3, cmos pipe and diode D3, the grid of cmos pipe connects No. 3 of oscillating circuit and goes out to hold Received signal strength, grid is connected with operating switch K by resistance R3 simultaneously, resistance R3 dividing potential drop makes to form electric potential difference between gate-source, the source electrode of cmos pipe is connected with operating switch K, and the drain electrode of cmos pipe is connected with the anode of diode D3; Motor M is connected with the negative electrode of diode D3, and another termination power cathode of motor M connects ground connection simultaneously, and fog scraping brush body connects motor.
When operating switch K stirs operation by external force, be connected with break back contact, circuit ON, cmos pipe output signal, motor movement, this body running of fog scraping brush, switch self-return.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
