The upper end of the pipe joint 32 is movably connected to a liquid inlet pipe 322, and a dynamic reflux port 323 is provided on the side of the lower end of the liquid inlet pipe 322. When the rotary cover 41 is opened, the liquid inlet pipe 322 moves relative to the pipe joint 32 so that the dynamic reflux port 323 is aligned with the fixed reflux port 321 for reflux. The liquid inlet pipe 322 is provided with a one-way liquid inlet valve 325 that allows the solution in the inner cavity of the container to enter the liquid storage chamber 3 in one direction. When the inflation membrane cavity is pressed to continuously inflate the inner cavity of the container, the material in the inner cavity of the container enters the liquid storage cavity accordingly. If the material entering the liquid storage cavity exceeds the amount required by the user, the user can act on the reflux regulating structure, that is, act on the liquid inlet pipe 322 to move relative to the pipe joint 32 so that the dynamic reflux port 323 and the fixed reflux port 321 can be aligned and connected for reflux. Excess material in the liquid storage cavity can be first refluxed into the inner cavity of the container, and then when the quantitative requirement is met, the reflux regulating structure can be closed, and finally the material in the liquid storage cavity that has undergone reflux adjustment can be poured out.

[0049] like Figure 2 As shown, in order to facilitate the adjustment of reflux, a stop key 22 is connected to the rotary cover 41, and a stop angle 324 is provided at the upper end of the liquid inlet pipe 322.

[0052] like Figure 5-10 As shown, the present invention also provides a refluxable inflating cap, comprising a connecting base 1, the connecting base 1 has upper and lower openings, a spacer 5 is provided between the upper and lower openings of the connecting base 1, and the upper part of the connecting base 1 is divided into a liquid storage chamber 3, the lower opening of the connecting base 1 is used to connect with the mouth of the container, the upper opening of the connecting base 1 is connected to a movable cover 4, a piston ring 40 is provided between the upper opening of the connecting base 1 and the movable cover 4, the upper end of the movable cover 4 is open and detachably connected to a rotary cover 41, and a spacer 5 is provided on the spacer 5 that can be connected to the container. The air inlet pipe 31 is sealed and slidable on the spacer block 5, and the upper and lower ends of the air inlet pipe 31 are respectively connected to the liquid storage chamber 3 and the inner cavity of the container. The spacer block 5 is also provided with a pipe joint 32 whose lower end is connected to the inner cavity of the container and whose upper end is placed in the liquid storage chamber 3.

A dynamic reflux port 323 is provided on the side of the air inlet pipe 31 and located in the liquid storage chamber 3, which can adjust the liquid storage amount in the liquid storage chamber 3 by adjusting the up and down sliding of the air inlet pipe 31. When the movable cover is moved up and down to continuously pump air into the inner cavity of the container, the material in the inner cavity of the container enters the liquid storage cavity accordingly. If the material entering the liquid storage cavity exceeds the amount required by the user, the user can operate the reflux regulating structure, that is, first open the screw cover, and then adjust the position of the movable reflux port 323 by adjusting the upward and downward sliding of the air inlet pipe 31, so that the excess material in the liquid storage cavity can be refluxed to the inner cavity of the container first, and then when the quantitative requirement is met, the reflux regulating structure is closed, and finally the material in the liquid storage cavity that has been adjusted and refluxed can be poured out.

[0053] In order to limit the upward and downward movement of the air intake pipe and thus avoid the air intake pipe from being separated from the spacer, a limiting protrusion 312 is provided on the air intake pipe 31 .

[0054] like Figure 5-8 As shown, the limiting protrusion 312 in this embodiment is arranged at the middle and lower ends of the air inlet pipe 31, and the upper end of the air inlet pipe 31 always extends out of the upper opening of the movable cover 4. When in use, the user opens the rotary cover and acts on the upper end of the air inlet pipe 31 to adjust the dynamic reflux port 323 to the corresponding position for reflux.

[0055] like Figure 9-10 As shown, the limiting protrusion 312 is arranged at the middle and lower end of the air inlet pipe 31, and the rotary cover 41 is connected with an adjusting column 411 which can be extended into the opening on the movable cover 4, and a matching connecting structure 412 is correspondingly provided between the upper end of the air inlet pipe 31 and the end of the adjusting column 411 so that after the rotary cover 41 is detached from the opening on the movable cover 4, the adjusting column 411 can be matched with the air inlet pipe 31 and connected, and the position of the dynamic return port 323 in the air inlet pipe 31 can be adjusted up and down. The connecting structure is a threaded structure. When the rotary cover is opened, the end of the adjusting column and the end of the air inlet pipe are connected by a thread, so that it is convenient for people to adjust the dynamic return port on the liquid inlet pipe.

[0056] To ensure reliable sealing, an inner ring sleeve 51 located in the liquid storage chamber 3 is formed by extending upward from the spacer 5 , and a sealing ring 52 is provided between the outer wall of the inner ring sleeve 51 and the inner wall of the movable cover 4 .

When the rotary cover 41 is opened, the air inlet pipe 31 moves relative to the reflux pipe sleeve 53, so that the dynamic reflux port 323 is aligned and connected with the fixed reflux port 321. During use, the movable cover is moved up and down to continuously pump air into the inner cavity of the container, and the material in the inner cavity of the container enters the liquid storage cavity accordingly. If the material entering the liquid storage cavity exceeds the amount required by the user, the user can act on the reflux regulating structure, that is, open the screw cap, and act on the air inlet pipe 31 to move relative to the reflux pipe sleeve 53 so that the dynamic reflux port 323 and the fixed reflux port 321 are aligned and connected, so that the excess material in the liquid storage cavity can be refluxed to the inner cavity of the container first, and then when the quantitative requirement is met, the reflux regulating structure is closed, and finally the material in the liquid storage cavity that has been adjusted and refluxed can be poured out.

[0058] In order to ensure that the inner cavity of the container has good sealing performance in the initial state, a one-way air intake valve 311 is provided on the air intake pipe 31 to allow the gas in the liquid storage chamber 3 to enter the inner cavity of the container in a one-way manner.

The upper end of the reflux pipe sleeve 53 is movably connected to a reflux regulating pipe 54 with upper and lower openings. A dynamic reflux port 323 is provided on the side surface of the lower end of the reflux regulating pipe 54. When the rotary cover 41 is opened, the air inlet pipe 31 moves relative to the reflux pipe sleeve 53 so that the dynamic reflux port 323 is aligned and connected with the fixed reflux port 321. A one-way liquid inlet valve 325 is provided on the reflux regulating pipe 54 and located above the dynamic reflux port 323, which allows the solution in the container cavity to enter the liquid storage chamber 3 in one direction. The spacer 5 is also provided with an air inlet pipe 31, the upper end of which extends upward and the lower end of which is connected with the container cavity.
