[0019] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model; obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments; based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] The utility model provides a technical scheme:

[0021] Embodiment 1:

[0022] A kind of inflation and deflation device, including air bag 1, air bag 1 is equipped with inflation port 2 and deflation port 3, still include:

[0023] air control one, is installed on inflation port 2, for controlling gas can only be discharged from inflation port 2 air bag 1 outside;

[0024] air control two, is installed on deflation port 3, for controlling gas can only be entered into air bag 1 by deflation port 3;

[0025] When implementing, the device can be used to the product needing inflation and deflation, including air bag product but not only limited to air bag product.

[0026] When deflating, the deflation port 3 is connected with the product air core, because the gas control device two in the air bag 1 can only control the gas to enter from the deflation port 3, and the gas control device one in the air bag 1 can only control the gas to exit from the inflation port 2, at this time, the air bag 1 is squeezed, the gas in the air bag 1 is discharged from the inflation port 2, and then the air bag 1 recovers the deformation to suck out the gas in the product, and the air bag 1 is repeatedly squeezed several times to discharge all the gas in the product, so that the product is conveniently stored.

[0027] When inflating, the inflation port 2 is connected with the product air core, and the inflation process is opposite, so that the product can be filled with gas, and the problem that bacteria is easily bred and odor is generated when inflating by the mouth in the prior art can be solved.

[0028] The gas control device one and the gas control device two can be set as one-way valves 8, and the installation directions of the two one-way valves 8 are opposite.

[0029] Embodiment 2:

[0030] Different from embodiment 1 is that the air bag 1 is designed as a split type, the air bag 1 includes an air bag body 4 and an end cover 5, and the air bag body 4 and the end cover 5 are sealingly connected through a connecting part. When the air bag body 4 and the end cover 5 are sealingly connected through the connecting part, the inflation and deflation functions in embodiment 1 can be performed; when the air bag body 4 and the end cover 5 are separated, the inside of the air bag body can be used as a container to store the air bag product after deflation, which is convenient and not easy to cause the air bag product to be lost.

[0031] As a further technical solution of embodiment 2, the connecting part includes a connecting port 6 and a limiting part 7, the connecting port 6 is arranged on the air bag body 4, and the limiting part 7 is arranged on the end cover 5, and the end cover 5 extends into the connecting port 6 to enable the air bag body 4 and the end cover 5 to be sealingly squeezed;

[0032] Specifically, the connecting part is composed of the connecting port 6 and the limiting part 7, which has a simple structure, low processing difficulty and low production cost; when assembling, only the limiting part 7 needs to be put into the connecting port 6, and the limiting part 7 can be sealingly squeezed with the connecting port 6 through the elasticity of the limiting part 7; when disassembling, only the end cover 5 needs to be pulled to pull out the limiting part 7 from the connecting port 6, and the assembly and disassembly are very convenient.

[0033] Further, a friction part is arranged on the surface of the air bag 1, the friction part is used to enhance the friction force when contacting the surface of the air bag 1, and the friction part is set as vertical lines 9 but is not limited to the vertical lines 9. The friction part is mainly arranged to improve the friction force between the hand and the air bag 1 during use, so that the air bag 1 is not easy to slip when being grabbed.
