For a person skilled in the art, they may understand the specific meanings of the above-mentioned terms in the present disclosure according to specific circumstances.

The embodiments of the present disclosure will be described in details below in conjunction with the accompanying drawings. In the case of no conflict, the following embodiments and the features in the following embodiments can be combined with each other.

The present embodiment provides an internal and external dual-purpose air pump, as shown in FIGS. 1 and 2, the internal and external dual-purpose air pump comprises a machine core, and the machine core comprises a housing 100 with an accommodating chamber and an inflating device provided within the accommodating chamber; the housing 100 is provided with an air outlet 121 and an air suction inlet 111 respectively in the bottom end and the top end, and the air outlet 121 and the air suction inlet 111 are both in communication with the accommodating chamber. The inflating device works to send the air flow out through the air outlet 121 and/or suction the air flow through the air suction inlet 111.

The air pump provided by the embodiment of the present disclosure can inflate or deflate a product to be inflated. In an exemplary embodiment, the product to be inflated can comprise a product capsule body, wherein the product capsule body can be provided with a first inflation/deflation port (not shown) which is used to communicate with the air outlet 121 or the air suction inlet 111 of the air pump. According to the exemplary embodiment, the air pump can be an internal and external dual-purpose air pump; on the one hand, the air pump can be used in an external purpose with respect to the product capsule body of the product to be inflated; on the other hand, the air pump can be used by being provided inside the airbag body of the product capsule body. It should be understood that in the present text the term “internal” comprises not only the case that the machine core is completely accommodated within the airbag body, but also the case that only a portion of the machine core is accommodated in the airbag body. In other words, the term “internal” should be understood that at least a portion of the air pump is accommodated in the airbag body of the product capsule body.

Firstly, the external use of the air pump provided by the embodiment of the present disclosure is described as follows.

According to the exemplary embodiment, when used externally, the air pump ca be used individually as an external air pump for inflation and suction. In an implementation method, the air pump can be used directly. For example, in an exemplary embodiment, in the case that the air pump is located outside the product capsule body of the product to be inflated, the air outlet 121 of the air pump can be directly connected to the first inflation/deflation port (not shown) of the product capsule body. In this case, the inflating device of the machine core can be activated, and the inflating device works so that the air flow is sent out through the air outlet 121 of the air pump and enters the product to be inflated via the first inflation/deflation port of the product capsule body, thereby achieving the inflating operation of the air pump (i.e., realizing the inflation for the product to be inflated by the air pump).

In addition, in another exemplary embodiment, in the case that the air pump is provided outside the product capsule body of the product to be inflated, the air suction inlet 111 of the air pump is directly connected to the first inflation/deflation port of the product capsule body of the product to be inflated. In this case, the inflating device of the machine core can be activated, and the inflating device works so that the air flow is suctioned from the product to be inflated via the first inflation/deflation port through the air suction inlet 111, so as to achieve the suctioning operation of the air pump (i.e., realizing the deflation operation for the product to be inflated).

According to the embodiment of the present disclosure, as shown in FIG. 2, in the external state, the first inflation/deflation port of the product capsule body communicates with the air outlet 121, which can achieve the inflation; or the first inflation/deflation port of the product capsule body communicates with the air suction inlet 111, which can achieve the air suction. According to the exemplary embodiment, the first inflation/deflation port of the product capsule body can be communicated with the air outlet 121 or the air suction inlet 111 through an air nozzle, to achieve the inflation and suction.

According to the exemplary embodiment of the present disclosure, an inflatable product is provided, and the inflatable product comprises a product capsule body and the above-mentioned air pump. In the exemplary embodiment, the air pump can be provided externally with respect to the product capsule body of the product to be inflated, and the first inflation/deflation port of the product capsule body can be communicated with the air outlet 121 of the air pump to achieve the inflating operation; or the first inflation/deflation port of the product capsule body can be communicated with the air suction inlet 111 of the air pump to achieve the suctioning operation.

Although the external use of the air pump provided by the embodiments of the present disclosure is described in details in the above, it can be understood that a person skilled in the art can make appropriate modification and change to the above embodiments without departing from the scope of the present disclosure. For example, the size, the material, the shape and the like of the air outlet 121 and the air suction inlet 111 of the air pump can be changed appropriately, and the connection method between the air pump and the first inflation/deflation port can also be modified appropriately.

For example, although the case is described above that the air outlet 121 or the air suction inlet 111 of the air pump is directly connected to the first inflation/deflation port of the product capsule body of the product to be inflated so as to inflate or deflate the product to be inflated, it can be understood that the protection scope of the present disclosure is not limited to this. For example, in another form of realization, any other component, for example, a flexible hose and the like, can be provided to lead the air flow from the air outlet 121 of the air pump to the first inflation/deflation port of the product capsule body of the product to be inflated so as to inflate the product to be inflated, or to lead the air flow from the first inflation/deflation port of the product capsule body of the product to be inflated to the air suction inlet 111 of the air pump so as to deflate the product to the inflated.

In addition, it can be understood that according to the embodiment of the present disclosure, the air outlet 121 or air suction inlet 111 of the air pump can be provided thereon with a component which is appropriate to associate with the first inflation/deflation port or any other component (for example, the flexible hose) for leading the air flow, for example, a buckling member and the like. Through the above method, accidental disengagement of the air pump can be prevented during work.

In addition, it can be understood that in the case of the external use, the specific material, shape and configuration of the product capsule body of the product to be inflated will not be restricted in any way, as long as the product capsule body is provided with the first inflation/deflation port which can be connected with the air outlet 121 and the air suction inlet 111 of the air pump according to the present disclosure.

It should be understood that the above described embodiment and its variations, and any other modification without departing from the spirit of the present disclosure shall be deemed falling into the protection scope of the present disclosure.

Next, the internal use of the air pump provided in the embodiment of the present disclosure will be described.

Here, in order to achieve convenient understanding, the configuration of the product capsule body for the internal use of the air pump will be firstly described.

It should be understood that the configuration of the product capsule body for the internal use of the air pump may be different from the abovementioned product capsule body for the external use of the air pump. For example, the product to be inflated can be provided with at least one of a first product capsule body and a second product capsule body, wherein the first product capsule body is configured to be connected with the air pump for the external purpose, while the second product capsule body is configured to be connected with the air pump for the internal purpose. As the air pump provided by the embodiment of the present disclosure is an internal and external dual-purpose air pump, the air pump of the present disclosure can be used to inflate and deflate the product to be inflated in any case.

Referring to FIGS. 3 and 4, in the case that the air pump is used internally, the product capsule body of the product to be inflated comprises an airbag (not shown) and a body 400 press-fitted on the airbag, and a second inflation/deflation port 410 is disposed in the body 400, and the body 400 is provided with grooves in the end portion away from the second inflation/deflation port 410. According to the exemplary embodiment, the body 400 can adopt a tubular structure which has an upper opening.

As shown in FIG. 5, the body 400 is provided with an upper cap 500 at the end away from the inflation/deflation port 410. According to the exemplary embodiment, a sealing structure is provided between the upper cap 500 and the body 400, which has the function of sealing and waterproofing. For example, the sealing structure can comprise a sealing groove which is provided in one of the body 400 and the upper cap 500 and a sealing ring 600 provided in the sealing groove. In this way, the sealing between the upper cap 500 and the body 400 is achieved.

In addition, as shown in FIG. 6, according to the exemplary embodiment, the body 400 can be provided with a check valve 411 for opening or closing the second inflation/deflation port 410. When the check valve 411 is opened, the second inflation/deflation port 410 opens, and at this moment, the air flow can flow through the second inflation/deflation port 410; when the check valve 411 is closed, the second inflation/deflation port 410 will be closed, at this moment, the air flow cannot flow through the second inflation/deflation port 410. In the above, the check valve 411 can be only opened when it is exerted a force along a direction that the check valve 411 is away from the internal chamber of the body 400.

It can be understood that, according to the exemplary embodiment, the body 400 may be provided with a reset member, for example, a spring, for keeping the check valve 411 in a closed state. In this way, the second inflation/deflation port 410 is usually in a closed state, so as to prevent water or pollutant from entering the body 400.

It can further be understood that the air flow flowing inside the inflating device can exert a force to the check valve 411 along the direction that the check valve 411 is away from the internal chamber of the body 400 when the inflating operation of the air pump is performed, so that the second inflation/deflation port 410 can be opened.

According to the exemplary embodiment, as shown in FIG. 6, a sealing gasket 412 can also be provided between the check valve 411 and the second inflation/deflation port 410, for example, an O-shaped ring, so as to apply sealing between the check valve and the second inflation/deflation port 410.

According to the exemplary embodiment, the body 400 can be provided with both the sealing ring 600 and the sealing gasket 412, so as to seal both the opposite sides of the body 400 at the same time, i.e., providing a double sealing.

In addition, according to the exemplary embodiment, as shown in FIG. 7, the body 400 can also be provided with a safety screen 800, and the safety screen 800 is used to seal around the check valve 411 and the second inflation/deflation port 410, so as to protect the check valve 411 and the second inflation/deflation port 410 from contamination by foreign matters such as dust.

It should be understood that the details of the product capsule body described above are not restricted, and based on the embodiments of the present disclosure, a person skilled in the art could conceive of variations, and all such variations shall be deemed falling into the protection scope of the present disclosure.

Next, the case will be described below that the air pump provided by the embodiment of the present disclosure inflates the airbag of the product capsule body when the air pump is placed inside the product capsule body of the product to be inflated.

In the present text, for the purpose of convenient description, the end of the machine core provided with the air suction inlet 111 is referred to as the top end, and the end of the machine core provided with the air outlet 121 is referred to as the bottom end. It should be understood that the terms “top end” and “bottom end” do not limit the actual orientation of the use of the machine core, and during the work, the top end (i.e., the end provided with the air suction inlet 111) of the machine core can also face downwardly, while the bottom end (the end provided with the air outlet 121) of the machine core can also face upwardly.

According to the exemplary embodiment of the present disclosure, the machine core can be inserted into the body 400 at the end away from the second inflation/deflation port 410, and the air outlet 121 can be made to communicate with the inflation/deflation port 410, thereby achieving the inflating operation. In the exemplary embodiment, the machine core can be inserted into the body 400 in a way that the air outlet 121 faces the second inflation/deflation port 410 of the body 400. In this case, according to the exemplary embodiment, the machine core of the air pump can be completely accommodated in the body 400, and the air outlet 121 communicates with the second inflation/deflation port 410 of the body 400, and thus the inflating operation of the air pump can be achieved. It can be understood that in this case, the air suction inlet 111 is located at the top end of the machine core and located back to the second inflation/deflation port 410 of the body 400.

The connection between the machine core and the body 400 in such circumstance (i.e., when the machine core is inserted into the body 400 in a way that the air outlet 121 of the air pump faces the second inflation/deflation port 410 of the body 400) will be described hereinafter in details.

In the present embodiment, as shown in FIG. 2, according to the exemplary embodiment of the present disclosure, the housing 100 of the machine core comprises an upper housing 110 and a lower housing 120. Referring to FIGS. 8-10, the upper edge of the upper housing 110 extends outwardly to form a sidewall 101 of the upper housing; the sidewall 101 of the upper housing can be disposed with a shaft hole for the penetration of the rotary shaft 220; and the body 400 is provided with a groove 401 therein for the insertion of the rotary shaft 220.
