Abstract

A self inflatable inflation product comprises at least an inflation air chamber and at least a sponge body part, wherein the sponge body part comprises a sponge body, a sealing jacket which braces on the outer surface of the sponge body and an air valve equipped on the sealing jacket, the sealing jacket is separated with the inflation air chamber, and a one-way valve which makes the air can only flow from the sealing jacket to the inflation air chamber between both.

Description

Can self-aerated aerated product

Technical field

The utility model relates to a kind of inflatable objects, particularly a kind of do not need to rely on extra inflation pump and only rely on that inflatable objects itself can charge and discharge pneumatic work can self-aerated aerated product.

Background technology

Employed aerated product is varied in people's work at present, the life, as balloon, airbed, water wing or the like.Various aerated product biggest advantage are that all after exitting when aerated product does not use, volume can contract lessly, conveniently preserve and carry, and when using, and the air chamber of aerated product is put on the air to be expanded to set shape and can to finish set function.

But existing aerated product all needs to rely on beyond the product or the inflation pump that is inlaid in the product charges and discharge gas, just must rely on extra inflation pump to put on the air.

Summary of the invention

The purpose of this utility model provides and does not a kind ofly need to rely on inflation pump and can self-aerated aerated product.

To achieve the above object, the technical solution of the utility model is as follows:

A kind of can self-aerated aerated product, comprise at least one inflatable air chamber, at least one cavernous body part; Described pars cavernosa urethrea virilis branch comprises the sponge body, be coated on the sealing shroud of this external surface of sponge and be installed in air valve on the sealing shroud; Described sealing shroud and described inflatable air chamber are isolated, but are equiped with a check valve that makes gas can only be flowed to inflatable air chamber by sealing shroud between the two.

Some extension of the sealing shroud of described cavernous body is installed in the inflatable air chamber, and described Non-return air valve also is installed between this a part of cavernous body and air chamber.

Some extension of described inflatable air chamber is installed in the sealing shroud of cavernous body, and described Non-return air valve also is installed between this a part of cavernous body and air chamber.

Also be equiped with an air valve that communicates with the external world on the described plenum chamber.

Described check valve comprises housing, seal strip and spring; Housing is installed between described sealing shroud and the air chamber, and housing is provided with the air extractor vent that leads to sealing shroud and air chamber respectively; Spring one end is installed on the inside face of housing, and the other end is equiped with seal strip and seal strip withstood and makes it cover the air extractor vent that leads to sealing shroud.

Described air valve adopts existing various air valve all can.

Owing to adopt above-mentioned structure, open the air valve on the cavernous body sealing shroud partly, extraneous gas enters sealing shroud, and sponge body inflation is closed the air valve on the sealing shroud again, at this moment, the air valve of other inflatable air chamber is closed always, rolls the cavernous body part, and gas wherein washes that check valve enters other air chamber between sealing shroud and other air chamber open, repeat said process, can realize inflation air chamber; After other inflatable air chamber inflation enough is shaped, open the air valve on the sealing shroud again, allow cavernous body part inflation, promptly whole aerated product finish inflation, to be shaped, that is to say, realized the inflation certainly of aerated product.

The realization of deflation course also is easy to, open the air valve of air chamber earlier, roll the cavernous body part, at this moment, air valve on the sealing shroud is closed, and gas wherein washes that check valve enters other air chamber between sealing shroud and other air chamber open, emits gas wherein, be that gas in the gentle chamber of cavernous body part is all emitted, whole aerated product has been realized venting.

The specific embodiment

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

Shown in Fig. 1 to 4, a kind of can self-aerated airbed, the pillow and the armrest portion 2 that comprise the bed body portion 1 that constitutes by sponge, constitute by inflatable air chamber;

Be equiped with an air valve 21 that communicates with the external world on the inflatable air chamber 2;

Bed body portion 1 comprises sponge body (not drawing among the figure), is coated on the sealing shroud 11 of this external surface of sponge and is installed in air valve 12 on the sealing shroud; Sealing shroud 11 is isolated with described inflatable air chamber 2, but be equiped with a check valve 3 that makes gas can only flow to inflatable air chamber 2 between the two by sealing shroud 11, sealing shroud 11 some extension of described cavernous body are installed in (also can be set to inflatable air chamber 2 some extension is installed in the sealing shroud 11 of cavernous body) in the inflatable air chamber 2, described Non-return air valve also is installed between this a part of cavernous body and air chamber, that is to say, check valve is adopted concealed structure design, be not exposed on the external, the collision people cause discomfort in preventing to use; Check valve 3 comprises housing 31, seal strip 32 and spring 33; Between the sealing shroud 11 and air chamber 2 that housing 31 is installed in, housing 31 is provided with the

air extractor vent

111,21 that leads to sealing shroud 11 and air chamber 2 respectively; Spring 33 1 ends are installed on the inside face of housing 11, and the other end is equiped with seal strip 32 and seal strip 32 withstood and makes it cover the air extractor vent 111 that leads to sealing shroud 11.

Open the air valve 12 on the sealing shroud 11 of a body portion 1, extraneous gas enters sealing shroud 11, sponge body inflation, close the air valve 12 on the sealing shroud 11 again, at this moment, the air valve 21 of pillow and handrail inflatable air chamber 2 is closed always, roll sponge bed body 1, gas wherein washes that check valve 3 enters air chamber 2 between sealing shroud 11 and the air chamber 2 open, repeats said process, can realize the inflation to air chamber 2, after air pillow and handrail 2 inflations enough are shaped, open air valve 12 again, allow the sponge inflation of a body portion 1, promptly whole mattress is finished inflation, be shaped.

The realization of deflation course also is easy to, close gas check valve 12, roll sponge bed body portion 1, gas wherein washes that check valve 3 enters air chamber 2 between sealing shroud 11 and the air chamber 2 open, open the air valve 21 of air chamber 2 again, emit gas wherein, promptly the gas in sponge bed body 1 and the air chamber 2 is all emitted, and whole airbed has been realized venting.

Fig. 5 to Fig. 8 is that existing check valve 4 is installed in the situation on airbed, but its principle is identical, and no longer good horse is stated herein.

As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all is a casehistory, is not only.All in the utility model scope or the change that is being equal in the scope of the present utility model all be included in the utility model.
