Summary of the invention
The purpose of this utility model is to provide a kind of pressurized air for windshield except rain device, and this device can provide different removing pressure and the supply that can guarantee to remove pressure in different rainfall situations.
The utility model solves the technical scheme that its technical matters adopts:
A kind of pressurized air for windshield is except rain device, comprise and be located at removing rain air receiver and being located at one group of compressed-air atomizer of windshield surrounding in automobile, the described rain device that removes also comprises solenoid regulated valve, is arranged at the automobile combined switch of automobile cab and is positioned at the direct supply of automobile; The described admission port except rain air receiver is connected with the air extractor duct of wet air receiver in automobile, describedly removes the air extractor duct of rain air receiver and the entrance of solenoid regulated valve is connected, and the outlet of solenoid regulated valve is connected with compressed-air atomizer; The magnet coil loop in series of locking press button, adjusting knob and the solenoid regulated valve in described direct supply and automobile combined switch.
Further, the described rain device that removes also comprises the micro-air compressor of being located in automobile, and the air extractor duct of micro-air compressor is connected with the admission port except rain air receiver; The described barrel except rain air receiver is provided with pressure switch, the open contact of described pressure switch is connected with the motor of micro-air compressor, and the series arm that in the adjusting knob in its series arm and automobile combined switch and solenoid regulated valve, magnet coil forms is in parallel.
In such scheme, except rain air receiver is for storing the pressurized air of wet air receiver and micro-air compressor transmission, as the power of removing raindrop; Solenoid regulated valve is realized the different aperture of valve according to size of current different in circuit; Pressure switch can be responded to except the pressure in rain air receiver, and when pressure is during lower than setting value, open contact i.e. the closed circuit of connecting; Automobile combined switch is arranged at operator's compartment, utilizes locking press button and adjusting knob composition control circuit wherein, facilitates navigating mate to controlling to adjust except rain device.
The beneficial effects of the utility model are except rain air receiver and the original compressed air system of solenoid regulated valve access automobile, to realize different removing pressure is provided in different rainfall situations; Operation pressure by pressure switch perception except rain air receiver, controls the start and stop of micro-air compressor then, realizes the removing pressure feed in the time of insufficient pressure, has guaranteed the normal operation except rain device.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is circuit diagram of the present utility model;
1. except rain air receiver; 2. solenoid regulated valve; 3. compressed-air atomizer; 4. wet air receiver; 5. pressure switch; 6. micro-air compressor; 7. motor; 8. automobile combined switch; 9. locking press button; 10. adjusting knob; 11. direct supplys; 12. first connection pipes; 13. second connection pipes; 14. the 3rd connection pipes; 15. the 4th connection pipes.
The specific embodiment
Shown in Fig. 1 and Fig. 2, the admission port except rain air receiver 1 of being located in automobile is connected by the first connection pipe 12 with the air extractor duct of wet air receiver 4 in original compressed air system in automobile, remove the air extractor duct of rain air receiver 1 and the entrance of solenoid regulated valve 2 and be connected by the 3rd connection pipe 14, the outlet of solenoid regulated valve 2 is connected by the 4th connection pipe 15 with the one group of compressed-air atomizer 3 that is arranged at windshield surrounding; It is indoor that automobile combined switch 8 is located at vehicle drive, the magnet coil loop in series of locking press button 9, adjusting knob 10 and solenoid regulated valve 2 in direct supply 11 and automobile combined switch 8 in automobile; Except the barrel of rain air receiver 1 is also provided with pressure switch 5, micro-air compressor 6 is located in automobile, and the air extractor duct of micro-air compressor 6 is connected by the second connection pipe 13 with the admission port except rain air receiver 1; The motor 7 of the open contact of pressure switch 5 and micro-air compressor 6 is in series, and the series arm that in the adjusting knob 8 in its series arm and automobile combined switch 8 and solenoid regulated valve 2, magnet coil forms is in parallel; Except rain air receiver 1, solenoid regulated valve 2 and micro-air compressor 6 volumes are little, can be arranged on the position of the former rain brush transmission device of automobile.
