The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

In conjunction with Fig. 1-shown in Figure 4, the utility model hand-held type automobile washer mainly is to be made of assemblings such as motor 11, oblique wave wheel, plunger cylinder, the pump housing 7, nozzle 1 and handles 12, wherein:

Motor 11 adopts concatenation type electric tool motors, can adopt to exchange 220 volts or 12 volts of two kinds of power supply power supply modes of direct current, so this cleaning machine possesses domestic power supply and all spendable characteristics of power supply on vehicle, and is easy to use.

The oblique wave wheel is fixed on the motor transmission shaft 30, and motor 11 is after deceleration device slows down, and motor transmission shaft 30 drives the oblique wave wheel and rotates.This oblique wave wheel is made of a bearing block 29, a bearing 28 and a bearing gasket 27 assemblings, and its bottom bracket 29 is fixed with electronic power transmission shaft 30 usefulness keys, and it has a working surface that cooperates with the power transmission shaft transmission, and this working surface is processed into the arcwall face that roughly is oblique shape.Bearing 28 adopts thrust roller bearing, is assembled on the bearing block 29 with bearing gasket 27.

Plunger cylinder includes the assembly for plunger of being made up of three groups of plungers 24, plunger spring 25, plunger back-up ring 26, and assembly for plunger is contained in by plunger mat 8, oil cylinder 9 and oil cylinder seat 10 in conjunction with in the fixed cylinder body.Wherein oil cylinder seat 10 usefulness screws are anchored on motor 11, and oil cylinder 9 usefulness screws are anchored on oil cylinder seat 10.Described motor transmission shaft 30 passes oil cylinder seat 10 backs and puts in the oil cylinder 9 by bearing 31 supportings, and by oil sealing 32 sealings.Plunger mat 8 is anchored on oil cylinder 9 with the pump housing 7 shared screws, and is provided with O-ring seals 23 between plunger mat 8 and the oil cylinder 9.Described plunger mat 8 is provided with three by the uniform plunger hole 33 of periphery, three plungers 24 that plunger spring 25 and plunger back-up ring 26 are housed are located in the oil cylinder 9, and the rearward end of each plunger 24 contacts with the transmission of oblique wave wheel end face, leading section puts in each corresponding water stream channel 15 of the pump housing 7 after passing corresponding plunger hole 33, and, make oil cylinder 9 constitute the cavity of a sealing with one-way sealing Y shape circle 20, oil sealing frame 21 and the sealing of oil sealing 22 assemblies.

Be provided with three water stream channels 15 that communicate with the plunger cavity in the pump housing 7, a pair of check valve is housed in each passage, each check valve is by valve body 18, spring 19, valve 15 and O-ring seals 16 formation of assembling.Two check valves are arranged on by valve seat 5 front and back in the water stream channel 15 of the pump housing, constitute the anterior water inlet check valve 6 that goes out water one-way valve 4 and rear portion.
