In this embodiment, the edge of the opening of the air bag 220 is wound around the first gasket 216, so that the edge of the opening is pressed and fixed by the end cap 213 and the first gasket 216, and the air bag 220 isolates the storage chamber in the barrel 210 from the external space, thereby achieving the purpose of preventing pollution. Meanwhile, when the balloon 220 is expanded, since the inside of the balloon 220 can be communicated with the outside through the breathing port 214, the pressure can be balanced with the outside, so that the balloon 220 can be easily expanded synchronously when the medium in the storage chamber is reduced, the pressure in the storage chamber can be balanced with the outside, and the medium can be conveniently discharged, and vice versa.

In this embodiment, the receiving means includes an airbag cup 230, a confinement ring 232, and a connecting portion 233. The airbag cup 230 is cup-shaped with an opening at one end, and the edge of the opening of the airbag cup 230 is detachably secured under the end cap 213, and the retracting device is accommodated in the airbag cup 230 when in the retracted state. Further, the edge of the opening of the airbag cup 230 is interference fit with the clamping groove of the first gasket 216 to be engaged with the first gasket 216, so that the airbag cup 230 and the airbag 220 can be taken out together when the end cap 213 is opened and the first gasket 216 is taken out.

In this embodiment, the bottom of the air bag 220 is connected to the bottom surface inside the air bag cup 230, and when the air bag 220 needs to be deployed, the opening edge of the air bag cup 230 is separated from the clamping groove of the first gasket 216, floats on the medium inside the barrel 210 together with the air bag 220, and floats upwards or downwards synchronously with the increase or decrease of the medium.

Referring to fig. 2 to 4, in the present embodiment, the bottom of the air bag cup 230 is an arc surface, and the opening of the air bag cup 230 is smaller than the bottom. In order to prevent the air bag cup 230 from blocking the discharge port 212 when it is placed at the position of the discharge port 212, a groove 234 is provided on the outer side of the bottom portion thereof, so that the discharge port 212 is not blocked even when the air bag cup 230 is abutted against the discharge port 212, and the medium can still flow.

It should be appreciated that in other embodiments of the present invention, the shape of the bladder cup 230 may be varied according to actual needs; the recess 234 on the outside of the bottom of the airbag cup 230 may also be omitted from shape changes, for example to a plate-like structure protruding, i.e. to ensure that the discharge opening 212 is not blocked.

Further, the bottom of the inner side of the airbag cup 230 is provided with a mounting seat 231, and the mounting seat 231 is a cylinder with external threads. The membrane of the air bag 220 is sleeved on the mounting seat 231. The connection part 233 is formed in a bar shape, has an internal thread at one end thereof, and is screw-coupled with the mounting seat 231 of the air bag cup 230, and the film at the bottom of the air bag 220 is clamped between the internal and external threads. The other end of the connecting portion 233 extends toward the end cap 213 and protrudes beyond the breathing opening 214 in the end cap 213. In this embodiment, the end of the connecting portion 233 extending out of the breathing port 214 is interference fit with the breathing port 214, thereby fixing the connecting portion 233 and the airbag cup 230 to the end cap 213. It should be understood that in other embodiments of the present invention, the connection portion 233 and the end cover 213 may be engaged by a snap fit, and the connection portion 233 may be rotated by a certain angle to unlock the snap fit, so as to move relative to the end cover 213; the connection portion 233 and the mounting seat 231 may be engaged by other means such as interference fit.

When it is desired to deploy the airbag 220, the airbag 220 can be deployed by pressing the connection portion 233 to disengage it from the end cap 213 and simultaneously disengaging the airbag cup 230 from the first gasket 216.

In this embodiment, the air bag cup 230 is provided with a constraint ring 232, and the constraint ring 232 is a cylinder with two open ends, one end of which is larger and the other end of which is smaller. The smaller one-end opening edge has a radially extending pressing portion that is pressed between the connecting portion 233 and the bottom of the airbag cup 230, and thus is fixed. The outer peripheral side of the restriction ring 232 and the inner side of the airbag cup 230 form a housing space in which the airbag 220 in the contracted state can be housed. The larger end of the confinement ring 232 forms an annular opening with the airbag cup 230 from which the airbag 220 deploys in an orderly fashion.

Further, in order that the pressing portion of the restriction ring 232 does not crush the airbag 220 when pressing the bottom of the airbag cup 230 at the time of assembly, a second gasket 235 is provided between the smaller end of the restriction ring 232 and the airbag 220 film to protect the airbag 220 film.

The usage method and beneficial effects of the storage tub 200 of the present embodiment are as follows:

when the storage chamber is filled with the medium to be stored or the storage tub 200 is empty, the connection part 233 is fixed to the end cap 213 together with the storage device. When the medium is required to be discharged, the connection part 233 can be pressed down, the connection part 233 falls down along with the storage device, the air bag 220 can be expanded or contracted according to the amount of the medium in the barrel, and the inside of the air bag 220 is communicated with the outside through the breathing port 214, so that the air pressure is balanced. Because the air bag 220 expands or contracts with the medium, the medium can still be discharged well under the condition that the inlet 211 is closed, and the medium in the barrel is isolated from the outside air in the whole process, so that the medium cannot be polluted by the outside. The airbag 220 or the receiving means can be replaced or repaired by opening the end cap 213.
