Description

Aerated pump

The utility model relates to a kind of air pump that can inflate inflatable toys easily.

Because it is inflations such as inflatable toys, balloon are not only required great effort, and unhygienic with outspoken connecing; Use other inflator or gas cylinder as air-inflating tools, not only cost is higher, and carries, operates equal inconvenience.Therefore the applicant has disclosed a kind of gas-filled pump in Chinese patent ZL98252200.2, and it is that air outlet mouth position at elastic material inflation body is provided with an one-way valve, offers inlet hole on the inflation body.During use, the mouth of inflating body is stretched in the valve of inflatable toys, live in pore with stick shift, body is inflated in extruding, intrinsic gas is poured in the inflatable toys get final product.Though, still have following shortcoming though this gas-filled pump has had advantage with low cost, easy to use than original inflatable tool:

1, complex structure.Because one-way valve is arranged on mouth, so the mouth member increases, the steam outlet pipe of sheathed split again on one-way valve, and mould increases, and complex process, manufacture cost still are reduction most possibly.

2, must live in pore with stick shift in the use, the intrinsic inflation body that is squeezed into could be prevented that gas is excessive, intrinsic being squeezed into could be inflated in the thing.

3, owing to open wide inlet hole is set, promptly use stick shift to live in pore, be difficult to prevent fully that gas leakage from overflowing yet, using effect is not very good.

4, one-way valve is arranged on the air outlet of body gas---mouth, when extruding is given vent to anger, must damping function be arranged to intrinsic gas.

The purpose of this utility model be exactly provide at the deficiency of prior art a kind of simple in structure, manufacture easily, use aerated pump more convenient, good charging.

The purpose of this utility model is achieved in that a kind of aerated pump, and it comprises the inflation body and be arranged on one-way valve on the body, and inflation body top is the mouth of giving vent to anger, and wherein said body is provided with hole, and one-way valve stretches into the body setting from hole.

Described hole can be arranged on the bottom or the sidepiece of body.

The described hole outside has one and fixedly uses concave station.

Put the case analysis as can be known according to above-mentioned technology, the utlity model has simple and reasonable for structurely, mould is less, and work simplification is manufactured easily, and is with low cost, easy to use, airflow smooth, advantage such as the inflation effect is good.

Fig. 1 is a cross-sectional view of the present utility model;

Fig. 2 is an one-way valve structures schematic representation of the present utility model.

Referring to Fig. 1, the utility model is a kind of aerated pump, it comprises inflation body 1 and is arranged on one-way valve 2 on the body, one-way valve be from top longitudinally cutting one joint-cutting relative cut open sheet (detailed structure of one-way valve as shown in Figure 2, can with ZLZL98252200.2 in to disclose structure consistent).Inflation body 1 top is the mouth 3 of giving vent to anger, body 1 can with mouth 3 design that is formed in one, need not establish accessories such as being conical steam outlet pipe in addition.Simplify mould structure, the convenient manufacturing.Be provided with hole 4 in the bottom of body 1 in addition, one-way valve 2 stretches in the body 1 from hole 4 and is provided with, and hole 4 outsides have one fixingly to use concave station, and one-way valve 2 can be inserted concave station, plays the effect of fixedlying connected with body 1.

In use, mouth 3 can be inserted in the inlet hole that is inflated thing, with the random extrusion body 1 of hand, because the single file conducting effect of one-way valve 2, gas can be from 2 mouthfuls of leakages of one-way valve, and gas can enter by mouth 3 unblockedly and be inflated in the thing, finishes that intrinsic gas is charged into the process that is inflated in the thing; After decontroling hand, body 1 outer gas is subjected to the effect of atmospheric pressure, washes one-way valve 2 open, and enters in the body by one-way valve 2; User's 1 pair of extrusion body once more is inflated thing and inflates; Repetitive operation is substituted the bad for the good till the gas up to being inflated thing.Whole operation is very simple and convenient, and the operator who is suitable for any age more uses.

Claims (3)

1, a kind of aerated pump, it comprises the inflation body and is arranged on one-way valve on the body, and inflation body top is the mouth of giving vent to anger, and it is characterized in that: described body is provided with hole, and one-way valve stretches into the body setting from hole.

2, aerated pump according to claim 1 is characterized in that: described hole can be arranged on the bottom or the sidepiece of body.

3, aerated pump according to claim 1 is characterized in that: the described hole outside has one and fixedly uses concave station.
