    Car windshield washer nozzle
    The present invention relates to a windshield washer nozzle of an automobile.
    As is well known, the windshield washer device for automobiles includes a washer fluid tank fixed to a fender apron panel of an engine compartment, a pump installed in the washer fluid tank, a hose connected to the pump, fixed to a hood panel, and fixed to a cowl panel. Consists of a nozzle and a wiper blade, the wiper switch is turned on to drive the pump to spray washer fluid from the nozzle to the windshield glass, and the wiper blade rotates to wipe the windshield glass.
    However, when the wiper switch is turned off, the nozzle is fixed to the hood panel, and the washer fluid falls on the hood panel, contaminating the hood panel, causing damage to the coating film. Since the nozzle is protruding, noise is generated while driving and the appearance is bad. Is there.
    SUMMARY OF THE INVENTION An object of the present invention is to provide a windshield washer nozzle for an automobile, which has corrected the above problems to prevent contamination of the hood panel, to prevent the occurrence of noise, and to enhance the appearance.
    The present invention comprises a cover hinged to the hood panel and the washer nozzle is fixed to the bottom surface, an actuator connected to the cover and the link, a transducer connected to the actuator and a pneumatic supply means connected to the transducer to achieve the above object. will be.

    1 and 2 in FIG. 1 is a cover, the cover (1) is hinged to one side to cover the hole (3) drilled in the hood panel (2) and at the same time the bracket installed on the inner surface of the cover ( 4) washer nozzle (5) is fixed to the washer liquid tank (not shown) and the hose (6), and the washer liquid receiver (7) for drilling the drain hole (7 ') is installed in the lower portion of the hole (3).
    8 is an actuator, in which the actuator 8 incorporates a piston 10 in the cylinder 9 together with the coil spring 11 to connect the rod 12 of the piston 10 to the bracket 4 and the link 13. To be connected.
    14 is a transducer. The transducer 14 installs an electromagnet 16 at one end of the case 15 and inserts the slider 18 together with the coil spring 17. The slider 18 has a through hole. (19) (19 ') (19) are formed in communication, and communication holes (20) (20') are formed in the case (15) so that the slider (18) is sucked by the excitation of the electromagnet (16). It is connected to the through-hole (19 ') 19, the communication hole (20, 20') is connected to the pneumatic supply means 27 and the cylinder (9) to be described later by the hose 22 (22 ') When the magnetism of the electromagnet 16 is lost and the slider 18 is retracted by the elasticity of the coil spring 17, the through hole 19 and the communication hole 20 are connected, and the through hole 19 is exhausted through the case 15. It is to be connected to the ball (21).
    In addition, the wiper switch 24 and the power supply 25 are connected to the electromagnet 16 via the relay 23, and the pump 26 is connected to the relay 23 by a conductor.
    27 denotes a pneumatic supply means, and the pneumatic supply means 27 connects the surge tank 28 to the tip of the hose 22 and vibrates by installing a switching valve 29 on the outlet side of the surge tank 28. The tank 30 is connected, and the switching valve 29 is connected to the start switch so as to open to the surge tank 28 side when the engine is driven and to the vacuum tank 30 side when the engine is stopped.
    According to the present invention as described above, when the wiper switch 24 is turned off, the electromagnet 1 of the transducer 14 is in a state in which the magnetism is lost, and thus the slider 18 is connected to the electromagnet 16 by the elasticity of the coil spring 17. Since the through hole 19 of the slider 18 is kept in communication with the exhaust hole 21, the pressure fluid of the surge tank 28 or the vacuum tank 30 is kept in communication with the atmosphere.
    If the pneumatic supply means 27 is maintained in communication with the air as described above, the piston 10 is also reversed by the elastic restoring force of the coil spring 11 and the link 13 connected to the rod 11 of the piston 10. By pulling the cover 1, the cover 1 is in a closed state.
    When the wiper switch 24 is turned on in the above state, the electromagnet 1 of the transducer 14 is excited to communicate with the hoses 22, 22 ′ and the through holes 19 ′ 19 of the slider 18. The pressure fluid of the pneumatic supply means 27 is supplied to the cylinder 9 to advance the piston 10 so that the link 13 connected to the rod 12 opens the cover 1, so that the washer nozzle 5 It is directed to the shield glass side, and the pump 26 is driven to spray the washer liquid to the washer nozzle 5.
    As described above, when the cover 1 is opened and the pump 26 is driven to be delayed by the relay 23 for a predetermined time, the washer nozzle 5 is completely directed toward the windshield glass and sprayed by the wiper blade rotation. Wiping the windshield glass.
    When the wiper switch 24 is turned off after wiping the windshield glass, the magnetism of the electromagnet 16 is lost and the pressure fluid communicates with the atmosphere, so that the piston 10 of the actuator 8 moves backward and the cover 1 is closed.
    In addition, the washer liquid falling from the washer nozzle after the end of the washer liquid is collected in the washer liquid receiver 7 can be discharged to the outside through the drain hole (7 ').
    As described above, the present invention hinges the cover to the hood panel to install the washer nozzle, and the hood panel is made by the washer liquid by directing the washer nozzle installed on the cover to the windshield glass side by the actuator, the transducer and the pneumatic supply means. Not only is it prevented from being contaminated, there is no damage to the coating film, the resistance element is removed during driving, there is no noise, and the appearance is beautiful.
