The air valve 12 communicates with the connecting part 25 through the inner hole 233 of the pressing part 23, and the connecting groove 231 communicates with the air inlet groove 251, so that the air valve 12 communicates with the connecting part 25. The pressing cover 24 covers the pressing part 23, sealing the space of the inner hole 233 of the pressing part 23 and preventing the gas in the inner hole 233 of the pressing part 23 from leaking, thereby improving the air inlet efficiency of the air valve 12.

[0055] Continue to refer to Figures 17 to 19 , Figure 17 Cross-sectional view of the liquid discharging device in the embodiment, Figure 18 Schematic diagram of the structure of the liquid discharging part and the flow foam adjusting part in the embodiment,Figure 19 It is a schematic structural diagram of the flow and foam regulator in the embodiment. Preferably, the liquid outlet device 2 further includes a flow and foam regulator 28. The flow and foam regulator 28 includes an adjusting wheel sleeve 281, a conical portion 282, and an anti-foaming column 283. A certain section of the liquid outlet member 22 is a conical hollow structure. The adjusting wheel sleeve 281 is sleeved outside the liquid outlet member 22. The conical portion 282 is adaptively arranged in the conical hollow structure of the liquid outlet member 22 and is screwed to the adjusting wheel sleeve 281. The anti-foaming column 283 is located inside the liquid outlet member 22. One end of it is connected to the conical portion 282, and the other end extends towards the liquid outlet of the liquid outlet member 22. The liquid flows through the gap between the conical portion 282 and the liquid outlet member 22, and the gap between the anti-foaming column 283 and the liquid outlet member 22.

[0056] Specifically, the second liquid outlet portion 222 of the liquid outlet member 22 has a hollow conical structure 2221, a liquid outlet pipe 2222, and a connecting pipe 2223. The hollow conical structure 2221 is located between the liquid outlet pipe 2222 and the connecting pipe 2223. The smaller end of the hollow conical structure 2221 is connected to one end of the connecting pipe 2223, and the other end of the connecting pipe 2223 is connected to the first liquid outlet portion 221. One end of the liquid outlet pipe 2222 is located inside the larger end of the hollow conical structure 2221, and the other end of the liquid outlet pipe 2222 is a bent open pipe to facilitate the outflow of liquid, that is, draft beer. The foam adjusting member 28 further includes a carrier seat 280, and the carrier seat 280 is sleeved outside the liquid outlet pipe 2222 and is close to the hollow conical structure 2221. The adjusting wheel sleeve 281 includes an adjusting wheel 2811 and an adjusting sleeve 2812. The adjusting wheel 2811 is sleeved outside the adjusting sleeve 2812 and is close to one end of the adjusting sleeve 2812. The adjusting sleeve 2812 is sleeved outside the carrier seat 280 and is movably connected thereto. The adjusting sleeve 2812 near the hollow conical structure 2221 has a limiting post 28121, and the larger end of the hollow conical structure 2221 has a limiting groove 22211. The limiting groove 22211 is arranged along the circumferential direction of the hollow conical structure 2221, and the limiting post 28121 is slidably connected in the limiting groove 22211. Through the cooperation of the limiting post 28121 and the limiting groove 22211, the rotation angle of the adjusting wheel 2811 is limited. The conical portion 282 includes a screwed pipe 2821, a conical pipe 2822, and a straight column 2823. The conical pipe 2822 is located between the screwed pipe 2821 and the straight column 2823. The larger end of the conical pipe 2822 is connected to the screwed pipe 2821, and the smaller end of the conical pipe 2822 is connected to the straight column 2823. There is a communication port 2824 between the conical pipe 2822 and the screwed pipe 2821. The connecting pipe 2223 is sleeved outside the straight column 2823, and a first gap is formed between the connecting pipe 2223 and the straight column 2823. The hollow conical structure 2221 is properly sleeved outside the conical pipe 2822, and a second gap is formed between the hollow conical structure 2221 and the conical pipe 2822. The adjusting sleeve 2812 is screwed to the screwed pipe 2821. By rotating the adjusting wheel 2811, the adjusting sleeve 2812 is rotated, and the screwed pipe 2821 screwed to the adjusting sleeve 2812 linearly moves, thereby driving the relative movement between the hollow conical structure 2221 and the conical pipe 2822, changing the interval width of the second gap, and thus realizing the adjustment of the width of the second gap, and further realizing the flow rate adjustment. One end of the defoaming column 283 is located inside the screwed pipe 2821, and the other end extends into the liquid outlet pipe 2222. A third gap is formed between the defoaming column 283 and the liquid outlet pipe 2222. The second gap and the third gap are communicated through the communication port 2824.

[0057] The draft beer that enters from the first liquid outlet part 221 will successively pass through the first gap, the second gap, and the third gap. When the draft beer passes through the first gap, the second gap, and the third gap, since the channel gaps through which it flows are relatively small, the foam of the beer will be squeezed, thus playing a role in defoaming. At the same time, the relatively small channel gaps will also change the flow rate and pressure of the beer flowing through the channels, which will also play a role in defoaming. The gap widths of the first gap and the third gap in this embodiment are fixed, thus playing a role in achieving a fixed defoaming effect, while the gap width of the second gap can be changed to achieve gap adjustment, so as to be able to perform dynamic defoaming for different beers, such as beers with different carbon dioxide contents. In this way, the adjustment of the flow rate and foaming amount of the draft beer is achieved through the setting of the flow rate foam adjustment member 28.

[0058] In summary, the high-pressure gas of the gas source part is filled into the extrusion space through the air valve. The high-pressure gas in the extrusion space squeezes the flexible container, so that the beer in the flexible container flows to the liquid outlet part through the liquid valve and finally flows to the outside from the liquid outlet part. During the whole liquid outlet process, air does not enter the flexible container, and the liquid in the flexible container is not contaminated at all, improving the shelf life and quality of the liquid in the flexible container. In addition, the whole portable beer barrel is small and portable, does not require electricity, and has a low cost.
