Description

Back side-intake type is taken out and is filled three function inflators

Technical field

The utility model relates to a kind of inflator, relates in particular to a kind of vacuum collecting bag of both can having given and bleeds, and can give water wing again, and the ball back side-intake type that waits inflatable product to inflate is taken out and filled three function inflators.

Background technique

At present, people will bleed with pump bowl when using vacuum collecting bag clothing organization in daily life, and will inflate with the inflator pump of big valve when using inflatable toys such as water wing, inflate with the inflator that has air tube again when inflating for ball stingy mouth product, owing to also there be not a kind of not only can bleeding but also can give the inflator of multiple inflatable product inflation at present, so much often need in other to buy three kinds of inflators respectively, both wasted money, carry deposit also cumbersome.

The model utility content

The technical problems to be solved in the utility model provides a kind of vacuum collecting bag of both can having given and bleeds, and can also take out to the back side-intake type of ball inflation simultaneously and fill three function inflators to the inflation of inflatable toys such as water wing again.

For addressing the above problem, side-intake type is taken out and is filled three function inflators it comprises cylindrical shell behind the utility model, handle, push rod, be positioned at the breather cheek valve of cylindrical shell, be positioned at the one-way exhaust valve of barrel front end, be used for air tube to ball inflation, be used for to water wing, the valve of inflatable toys such as balloon inflation, the rear end cover of shutoff cylinder back-end is characterized in that: the circular hole around the rear end cover center is processed with the annular boss that extends internally vertically, and elastic seal ring is fixed on the inside of annular boss by card, push rod passes the center hole of elastic seal ring and card, and is tightly connected with elastic seal ring; Barrel front end is processed with the tube shape bulge of the certain-length that stretches out, and air tube is connected with the endoporus of tube shape bulge is airtight by being threaded, and the inflation muzzle is inserted in the outside of tube shape bulge and is connected with boss is airtight; Back cover sidewall is processed with the sucking pipe that stretches out with cylindrical shell 1 internal communication.

As further improvement of the utility model be, be connected with soft frenulum between valve and the tube shape bulge, an end of soft frenulum is socketed in the outside of tube shape bulge, and the other end is socketed in the outside of charging air inlet.

After adopting such structure, the bleeding point that only needs in the time of need bleeding sucking pipe to be inserted in collecting bag gets final product, only needing in the time of need inflating to inflatable toys such as water wings needs the valve of inflatable product to get final product the charging air inlet insertion, when need giving ball inflation, can use the air tube inflation of exposing fully as long as charging air inlet pulled out from tube shape bulge, inflator is realized three kinds of functions, and not only economy but also save trouble was deposited more convenient.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is that side-intake type is taken out the front view that fills three function inflators behind the utility model.

Fig. 2 is that side-intake type is taken out and filled the plan view of three function inflator charging air inlets when tube shape bulge pulls out behind the utility model.

Fig. 3 is that side-intake type is taken out and filled the longitudinal sectional view of three function inflators along sucking pipe behind Fig. 1 the utility model.

Fig. 4 is that side-intake type is taken out and filled the partial enlarged drawing of three function inflator elastic seal rings with the push rod joint behind the utility model.

Embodiment

As Fig. 1, Fig. 2, Fig. 3, back side-intake type shown in Figure 4 is taken out and is filled three function inflators, it comprises cylindrical shell 1, handle 2, push rod 3, be positioned at the breather cheek valve 4 of cylindrical shell 1, be positioned at the one-way exhaust valve 5 of cylindrical shell 1 front end, be used for air tube 6 to ball inflation, be used for charging air inlet 7 to the inflation of inflatable toys such as water wing, the rear end cover 10 of shutoff cylindrical shell 1 rear end, the circular hole that passes for push rod 3 is arranged on the rear end cover 10, be processed with the annular boss 14 that extends internally vertically at circular hole around rear end cover 10 centers, elastic seal ring 12 is fixed on the inside of annular boss 14 by card 13, and push rod 3 passes the center hole of elastic seal ring 12 and card 13, and is tightly connected with elastic seal ring 12; Cylindrical shell 1 front end is processed with the tube shape bulge 8 of the certain-length that stretches out, and air tube 6 is connected with the endoporus of tube shape bulge 8 is airtight by being threaded, charging air inlet 7 cover be inserted in the outside of tube shape bulge 8 and with 8 airtight connections of tube shape bulge; Back cover 10 sidewalls are processed with the sucking pipe 11 that stretches out with cylindrical shell 1 internal communication.

In order to prevent charging air inlet 7 losses, be connected with soft frenulum 9 between charging air inlet 7 and the tube shape bulge 8, an end of soft frenulum 9 is socketed in the outside of tube shape bulge 8, and the other end is socketed in the outside of charging air inlet 7.

The bleeding point that only needs in the time of need bleeding sucking pipe 11 to be inserted in collecting bag gets final product, owing to push rod 3 with sealing by elastic seal ring 12 between the cylindrical shell 1, air can not enter from the joint of push rod 3 with cylindrical shell 1, during following handle 2, push rod 3 drives breather cheek valve 4 and moves down, one-way exhaust valve 5 is opened, breather cheek valve 4 is closed, gas between breather cheek valve 4 and the one-way exhaust valve 5 is discharged in air tube 6, in gas is drawn into cavity between breather cheek valve 4 and the rear end cover 10 by sucking pipe 11 from collecting bag simultaneously; On pulled handle 2 o'clock, push rod 3 drives on the breather cheek valve 4 and moves, breather cheek valve 4 is opened, one-way exhaust valve 5 is closed, gas enters in the cavity between breather cheek valve 4 and the rear end cover 10 in the cavity between breather cheek valve 4 and the one-way exhaust valve 5, and the reciprocating sliding handle can be discharged gas in the collecting bag like this; Only needing in the time of need inflating to inflatable toys such as water wings needs the valve of inflatable product to get final product charging air inlet 7 insertions, and gas will suck from sucking pipe 11, charges into by charging air inlet 7; When needs are given ball inflation, can use the air tube 6 that exposes fully to inflate as long as charging air inlet 7 pulled out from tube shape bulge 8.

Mode of execution of the present utility model is not limited to said structure; can be not necessarily circular such as sucking pipe 11; it also can be square; oval; can adopt the supporting sucking pipe of any and air-breathing product; also can link to each other with cylindrical shell 1 by the mode that is flexible coupling; charging air inlet 7 also can use any and the supporting valve of inflatable product; also can be connected with cylindrical shell 1 with the mode that is flexible coupling; be appreciated that every in the structural design that possesses can bleed sucking pipe and the charging air inlet that can inflate on the inflator simultaneously all within the utility model protection domain.
