Abstract

The utility model relates to an oscillatory type pumping device which is used for pumping liquid from a container. The utility model is provided with a pipe joint whose tail part is sheathed and connected with a rubber pipe; the front end of the pipe joint is connected with a pipe-shaped valve seat screw thread; the middle part of the inner wall of the valve seat is provided with a round of enlargement step; a sliding valve core is arranged in a hollow cavity between the valve seat enlargement step and the pipe joint. When used, the pumping device is inserted in a liquid storing container and is oscillated up and down. After the liquid overflows the rubber pipe, the oscillation is stopped; the outlet of the rubber pipe is positioned on the position lower than the liquid level of the container; the self flow of the liquid is achieved.

Description

Vibrating sucker

The utility model relates to a kind of liquid sucking device, particularly a kind of oscillating type aspirator that is used for aspirating low-viscosity (mobile) liquids such as gasoline, diesel oil, kerosene and water in container, its product can be widely used in aspects such as the interior pumping liquid of motor vehicle oil pumping, chemical industry and even ordinary family.

In the prior art liquid in the container is transported in another container, all adopts modes such as hand suction, electronic suction and the suction of tube capsule class hydrocone type usually, the equal more complicated of structure, volume is huger, the operating conditions restriction is many, and the life-span is short, and maintenance is also inconvenient.When Motor Vehicle transportation or maintenance, often can see the driver and adopt a kind of mode of quite simply pumping, an end that is about to a hose inserts in the oil storage container, with the air in the mouth draft tube, utilizing barometric pressure that oil is poured in the sebific duct pumps, but this method is very unhygienic, and as easy as rolling off a log with in the fluid suction port and cause intoxicating phenomenon.

The purpose of this utility model is the defective that overcomes prior art, so a kind of simple and reasonable, easy to use health is provided, volume is little, the life-span is long and the oscillating type aspirator that need not keep in repair.

In order to realize the foregoing invention purpose, technical solution of the present utility model is such: the theory structure of this oscillating type aspirator is the one-way valve type structure, it has the pipe joint that an afterbody is socketed with hose, the front end of pipe joint and a tubular valve seat scyewed joint, the middle part of valve base inner wall is provided with expands step a week and forms the valve port of one-way valve, is equiped with the sliding valve core that an one end can be sealed valve port in the cavity between valve port and pipe joint.During use, insert in the storage liquid container aspirator and vibration up and down.When aspirator moved downward, spool was opened automatically, and the liquid in the container enters in the aspirator through the gap of valve port along spool; When aspirator moves upward, the spool close port.After the vibration several times, liquid just is full of aspirator repeatedly.After treating that liquid overflows sebific duct, the failure of oscillations places the low position of container liquid level to the sebific duct outlet, then can realize the liquid gravity flow according to siphonage.

Below with reference to accompanying drawing a specific embodiment of the present utility model is illustrated.

Fig. 1 is the longitudinal profile diagrammatic sketch of this example structure.

With reference to accompanying drawing, the afterbody of pipe joint 3 is threaded, so that hose 4 can connect with it securely.Sliding valve core 2 is arranged at expanding in the cavity between step (valve port) and the pipe joint 3 of valve seat 1.Spool 2 by rate of specific gravity at 1.05～1.20 heat-resisting, oil resisting material such as ABS, herd polyvinyl chloride material is made, and is the tubbiness spool that a side-looking face is the T type, has through hole 21 on the sidewall of spool 2.In order to improve the functional reliability of whole device, expand the interior trailing edge of step at valve seat 1 and process a plane of inclination, simultaneously in plane of inclination that root edge periphery processing one circle of T type tubbiness spool 2 matches with the valve seat plane of inclination.When aspirator became vertical shape, spool 2 fell like this, and its plane of inclination, bottom is put and is pressed on the valve port plane of inclination, has realized the sealing that the two is good, prevents liquid return, had strengthened the pumping velocity of device.During concrete enforcement, the liquid pumping hole of valve seat 1 front portion can be processed into export-oriented horn shape.

The utility model mainly is made up of three parts, so its compact structure, volume are little, in light weight very convenient to carry.Whole aspiration procedure realizes according to siphonage and the height difference that makes full use of liquid, so saved manpower, electric power, has eliminated unnecessary waste and pollution.No matter aspirator simple to operate under any circumstance can both be finished by a people.

Claims
