CN2205881Y - Hand mini oil pump - Google Patents

Abstract

The utility model relates to hand mini oil introducing pump used for the oil feeding (suction) and the washing of the oil tanks of an automobile and a motorcycle. The utility model is provided with a tubular pump body and a slider which can be slid axially in the tubular pump body, the slider is provided with an axial through hole, the caging device of a valve sheet extended for definite distance is fixed on the end surface of the delivery side of the tubular pump body, and a valve sheet which can freely float is arranged on the inner side of the caging device of the valve sheet. The valve plate can be freely opened and closed by rocking the pump body by hands. When the pump body is held and rocked axially by the hands, the valve plate is slid backwards and forwards in the hand mini oil introducing pump to make the two ends of the valve plate produce pressure difference. The valve plate is repeatedly opened and closed following the slider slid backwards and forwards until oil liquid is sucked into the hand mini oil introducing pump and exhausted from a pump outlet, and then rocking is stopped.

Description

Hand mini oil pump

The utility model relates to a kind of pump that is used to extract small amount of liquid, is applicable to that specifically motorcycle adds the required and micropump that uses when (taking out) oil plant or automobile are interim is badly in need of adding (taking out) a small amount of oil plant.

Usually under the occasion, when people add (taking out) oil to automobile or motorcycle, adopt more original operating method mostly, promptly go in the fuel tank with a plastic tube skewer, the other end is put into mouth and is pulled at, make and produce negative pressure in the pipe oily sucking-off, utilize siphon principle that oil is continuously outflowed then, because of containing toxic substance in the gasoline, so this method is easily with in the through oil hole, both uncivil, unhygienic again.

The purpose of this utility model provides and a kind ofly is easy to carry, easy to use, be fit to automobile, motorcycle adds the miniature oil pump that (taking out) oil plant is used.

For achieving the above object, the utility model is designed to a kind of manually miniature oil pump that draws, it has a tubulose pump housing and one slide block in axial sliding in the pump housing, slide block has axial hole, but be fixed with the inboard valve block of placing a free floating of this device of valve block limit stoper that stretches out certain distance on the end face of its outlet side, the valve block outer rim has fuel-displaced breach.

When the utility model uses, the entrance point of the pump housing is connected flexible pipe and inserts fuel tank, hold the pump housing and axially shake several times, oil is flowed out from pump discharge through flexible pipe, promptly stop to shake this moment, and fluid continues to flow out by siphonage.

The utility model manually miniature oil pump that draws is similar to a bit of straight tube, can be contained in the pocket or in the handbag and carry, performance sensitive, very convenient, adopt to shake to add (taking out) oil, simple to operate, effective, be particularly suitable for automobile, motorcycle uses when adding (taking out) oil, and can be used as the special tool that cleans fuel tank.

Further specify structure of the present utility model and working principle below by accompanying drawing.

Fig. 1 is this pump operated state sectional view.

Fig. 2 is valve structure figure.

As Fig. 1, the pump housing 1 is gripped by hand 10, connect flexible pipe 7 on the pump housing entrance point pipe joint, the outlet end of the pump housing is equipped with circlip for hole 5, be provided with slide block 2 in the pump housing, slide block has axial hole 8, and it is the framework made from wire to fix a valve block limit stoper 4 on the end face of its outlet side, valve block 3 can be in framework free floating.The other end is provided with insulation rubber circle 9, and flexible pipe 7 is inserted fuel tanks, when the pump housing with hand when moving, slide block slidably reciprocates in the pump housing, when slide block slided to the right, the air of suction side was compressed and valve block 3 is washed open in the pump, air through the hole 8 by pump discharge 6 discharges; When slide block slided left, suction side produced negative pressure in the pump, and valve block 3 is subjected to the outlet end air pressure and closes, and part fluid sucks by flexible pipe; After repeating to shake several times, fluid is full of the interior space of pump and flows out from exporting 6, and can stop to shake this moment, and fluid continues to discharge from fuel tank because of siphonage.

Visible valve block 3 outer rims jagged 11 among Fig. 2.

Claims (2)

1, the manual miniature oil pump that draws, it is characterized in that having the tubulose pump housing and can be at pump body inner shaft to the slide block 2 that slides, slide block has axial hole 8, but be fixed with its inboard valve block of placing a free floating of valve block limit stoper that stretches out certain distance on its outlet side end face, the valve block outer rim has fuel-displaced breach.

2, the manually miniature oil pump that draws as claimed in claim 1 is characterized in that the valve block limit stoper is a framework.
