Abstract

The utility model relates to a sprinkler for the dust removing of the front windshield of the automobile and comprises a sprayer head, a water pipe, a micro pump, a high speed direct current motor and a water tank. Particularly, spherical shape inserts are inserted to the top end of a sprayer head rod. The hole diameter of an inner hole and the hole diameter of the water outlet of the insert are reasonable design. The micro pump is provided with the high speed direct current motor. The main devices are formed by blow molding and injection molding. The motorist just need to press at a push-button switch to start the water sprayer that the water can be ejected toward the windshield to remove the dust on the windshield. The utility model is portable and nimble, can fit for various automobiles and can be widely used for the plateau, the mountain area, the desert, the mining area, the petroleum, the survey and the capital construction worksite.

Description

Sprinkler for vehicle

The utility model relates to the preceding dedusting water injecting system of windshield.

On the automobile that China designs voluntarily and produces, also do not install this sprinkler at present, therefore long-distance running easily amasss full dust on the windshield of plateau, mountain area or desert region, influence driver vision, increase the driver fatigue sense, thereby safety traffic is brought certain danger.

The purpose of this utility model just provides a kind of automobile-used sprinkler.Automobile driver one is pressed button switch in operator's compartment, starting sprinkler can spray to water on the Windshield, draws together hydrophone and is used, and it is clean that dust on the Windshield is removed, the visual field of bright and clear chaufeur.

The utility model is finished as follows: configuration high-speed DC machine on micropump.Miniature delivery side of pump links to each other with water tank, and starter motor promptly drives the impeller in the micropump, and the impeller high-speed operation to coolant outlet pipe, ejects the hydraulic pressure in the water tank by the spherical inserts on the nozzle rod.Because automobile cab and Windshield front space are very little, so it is little that the volume of pump and motor, water tank all requires, weight requires light, can adapt to the assembling of various automobiles, therefore micropump and shower nozzle, motor housing, water tank all are plastic products, simultaneously, because water spray has certain requirement, require the water spray height about 2 meters, water flow pressure is stabilized in 0.6kg/cm ², simultaneously, require water outlet and bar endoporus aperture on the nozzle rod to have the dimensions, and be the power supply that adapts on the automobile the requirement of motor, generally adopt direct supply, and will reach 15000 rev/mins of rotating speeds.Torque 0.294NCm can have the long life-span in order to make motor, reaches every data of water spray simultaneously again, then adopts sealing arrangement between the motor and the pump housing.Spherical inserts on the shower nozzle can be regulated the water spray angle arbitrarily, makes it adapt to the angle of the Windshield of various types of automobiles.This automobile-used sprinkler is portable and smart, when making chaufeur on the plateau of travelling, mountain area, desert and mine, oil, exploration, infrastructure project building site, can remove the dust on the Windshield satisfactorily, improves drive safety.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is the utility model integral structure figure.Fig. 5 is the shower nozzle section-drawing.

Fig. 2 is that integral structure B is to view.Fig. 6 is an impeller view in the pump housing.

Fig. 3 is the micropump cutaway view.Fig. 7 is an impeller cutaway view in the pump housing.

Fig. 4 is the micropump longitudinal sectional view.Fig. 8 is a spherical inserts section-drawing on the nozzle rod.

Shower nozzle (1) with reference to Fig. 1 Fig. 2 plastics blow molding or injection mo(u)lding is received on fork type pipe mutually with plastic hose (11), be connected on the delivery port of micropump (5) by plastic hose (11) again, the shell of micropump (5) and high speed DC machine (9) also is plastics blow molding or injection molded type, and shell (10) and middle cover (7) and pump case seal the bonding integral body that becomes assembling afterwards with seccotine.The inflow point of micropump (5) and plastic cistern (3) join.After high speed DC machine (9) is activated, high-speed operation, Revolution Per Minute 15000 right side of turning left, torque is about 0.294NCm, and the impeller (6) that drives micropump (5) is high-speed operation also, the hydraulic pressure of water tank (3) lining to delivery port, enter coolant outlet pipe (11), then, water under certain pressure, i.e. 0.6kg/cm ²The time, wash away through the Windshield of spherical inserts on operator's compartment on the shower nozzle (1).Thereby dust on glass is rinsed well.2 is lids of water tank (3) among the figure, the 4th, and the joint of water tank (3) and micropump (5), the 8th, seal ring.

With reference to Fig. 3,4, the 21st, the high speed DC machine, the 22nd, the seal ring between motor and the pump, preventing that water from infiltrating motor internal and influencing electrical machinery life, the 23rd, pump case, the 24th, impeller, find out from cutaway view, should be gapped between impeller outer diameter and the pump case, according to actual tests, this gap should be between 0.15-0.20mm.For water is reached about 2 meters from the spherical inserts ejection of shower nozzle, then the pressure of water and flow velocity all will be selected a preferable numerical value, and the water ejection is highly reached about 2 meters.Seal with rubber seal between high speed DC machine 21 and the pump case 23, or, infilter motor cavity to prevent water with Graphite pad, teflon gasket sealing.

With reference to Fig. 5, Fig. 8, spherical inserts (31) on the shower nozzle links to each other with the shower nozzle endoporus, and shower nozzle endoporus aperture is chosen as and is not more than 3 millimeters, and shower nozzle inserts water outlet aperture is not more than 1 millimeter, so just can make the water outlet current be scattering shape flushing Windshield, the shower nozzle inserts forms with copper material car system.

With reference to Fig. 6,7, the impeller in the micropump is made 6 blades such as branch such as grade, also is to form with plastic injection-moulded.The right alignment of impeller outer diameter and endoporus is not more than 0.05 millimeter, if overproof, then the friction between impeller outer diameter and the pump case can influence rotating speed, and increases noise, reduces discharge pressure.
