Description

Aspirator

The utility model relates to a kind of aspirator, especially for the refueling operation of automobile, motor bike and various fuel oil machineries, also can standby family carry out various suction operations (for example changing water to fish jar).

The automobile of prior art, motor bike and various fuel oil machinery are often provided petrol storage tank for oneself at work, in order to fuel oil has consumed under near the situation that does not have a petrol service station, to refuel to car voluntarily.Usually the driver is when refueling to car, all be that hose one end is inserted petrol storage tank, use a firmly suction of the other end of mouth alignment tube then, to hold the operating oil tank that inserts car more rapidly, like this, oil in the petrol storage tank flows into operating oil tank through hose under the effect of suction, refuel to operating oil tank.In addition, when family changes water to fish jar, change water particularly for big fish jar, because big big, the heavy not Easy Move of fish jar volume, therefore also the method for above-mentioned mouthful of suction pipe commonly used is discharged the sewage in the fish jar, renews into clear water.Above-mentioned mouthful method of inhaling be so so also can solve the drain problem, and is still firmly excessive owing to be difficult to grasp with the strength of mouth imbibition, fuel oil and soiling solution promptly can suction nozzle in, even in can choke stomach, the lung, directly influence the healthy of people; Suction is little, and liquid can not be inhaled again; And refueling each time or changing in the water process, often to inhale repeatedly with mouth, bring a lot of inconvenience to work virtually, increased very big added burden.In order to address the above problem, the inventor designs a kind of aspirator finally and mends the deficiencies in the prior art with the fan through long term studies and test.

The purpose of this utility model provides a kind of aspirator, and it is to utilize to connect the liquid inlet and outlet pipe on a kind of rubber bladder of hollow, realizes the drain effect by people with hand extruding rubber bladder.Avoided having guaranteed the healthy of people in the soiling solution inflow entrance, reduced the burden in people's work.

The purpose of this utility model realizes by the following technical solutions, this aspirator is made up of liquid sucking bag, feed tube, drain pipe, connection pipe, import non-return flap, outlet non-return flap, filter screen, described liquid sucking bag is the leak free elastic sack body of a hollow, connect feed tube and drain pipe on it, and communicate with the liquid inlet and outlet pipe; Have outside thread on the described connection pipe, described liquid inlet and outlet Guan Yiduan has negative thread, and described liquid inlet and outlet pipe is with after each connection pipe is threaded, again by connection pipe and liquid sucking bag bonded assembly.One end of described each connection pipe is provided with integrated X-shape rack, and there are import non-return flap and outlet non-return flap to be attached at described each X-shape rack side respectively and to block this rack hole, described non-return flap is the thin type sheet material, the center of described non-return flap be fixed in the X-shape rack in the heart.

Described filter screen is arranged in the drain pipe.

The utility model has replaced mouth of the prior art to inhale operation owing to adopted the elasticity liquid sucking bag to carry out drain, has not only brought convenience to routine, has alleviated burden, and has guaranteed people's health, has increased safety for people's routine.

To further set forth the utility model to closing drawings and Examples below.

Fig. 1 is a three-dimensional exploded view of the present utility model.

Fig. 2 is an axial section scheme drawing of the present utility model.

Fig. 3 is that A of the present utility model is to view.

Referring to Fig. 1, Fig. 2, the utility model aspirator by liquid sucking bag 4, feed tube 1, drain pipe 7, connection pipe 2, import non-return flap 3, outlet non-return flap 8, and filter screen 5 form.Liquid sucking bag 4 is the leak free elastic sack body of a hollow, connects connection pipe 2, feed tube 1 and drain pipe 7 on it, and communicates with liquid inlet and outlet pipe 1,7; Have outside thread on the described connection pipe 2, described liquid inlet and outlet pipe 1,7 one ends have negative thread, and described liquid inlet and outlet pipe the 1, the 7th is after each connection pipe 2 is threaded, again by each connection pipe 2 and liquid sucking bag 4 bonded assemblys.One end of described each connection pipe 2 is provided with integrated X-shape rack 6 (seeing shown in Figure 3), and there are import non-return flap 3 and outlet non-return flap 8 to be attached at described each X-shape rack 6 side respectively and to block this rack hole, described non-return flap is the thin type sheet material, the center of described non-return flap be fixed in the X-shape rack in the heart.Described filter screen 5 is arranged in the drain pipe 7.

Connection pipe 2 can be bonding with the connection mode of liquid sucking bag 4 or be threaded; Filter screen 5 can adopt copper mesh, stainless (steel) wire, and all the other each parts adopt oil proof rubber.

During use, oil inlet 1 is inserted petrol storage tank, oil outlet pipe 7 inserts operating oil tank, firmly pushes liquid sucking bag 4 then, and capsule 4 produces distortion under pressure, its inner air pressure increases, import non-return flap 3 is subjected to the air pressure effect will produce distortion, but can't be out of shape under the stopping of intersection rack 6, can only be attached to tightly and block inlet on the rack, export non-return flap 8 deformation in compressions and do not have rack again and stop that the air in the capsule 4 is discharged by drain pipe 7 rapidly so open; At this moment unclamp liquid sucking bag 4 rapidly, capsule 4 is owing to the elastic restoring force effect of self restores to the original state, and in moment capsula interna 4, be vacuum state, exporting non-return flap 8 simultaneously closes, so the fluid in the petrol storage tank is under pressure, push import non-return flap 3 open and flow into oil inlets 1, pass capsule 4, push outlet non-return flap 8 open once more, inflow oil outlet pipe 7 filters impurity through filter screens 5 and enters operating oil tank at last, finishes the oil transportation operation.

In addition, non-return flap is owing to adopted very thin rubber pad, and intersect in the rack 6 in the heart because its centre is fixed in, therefore push down, distortion is the umbrella that narrows at pressure, the rack hole is exposed, form (or going out) hydraulic fluid port open mode, do the time spent or do not have pressure and do the time spent, can restore to the original state rapidly again at reversing sense pressure, block the rack hole, close hydraulic fluid port.

In addition, liquid sucking bag 4 can be made rugby shape, spheroidal, cylindrical or other arbitrary shape.
