[0051] The membrane filament 601 in the embodiment is made of polytetrafluoroethylene (PTFE), and the polytetrafluoroethylene has the characteristics of air permeability and water impermeability. The polytetrafluoroethylene is a high polymer material, the fluorine atoms in the molecular structure of the polytetrafluoroethylene are closely arranged to form micropores, the diameters of the micropores are smaller than those of water droplets but larger than those of air molecules, and therefore the polytetrafluoroethylene can allow air to pass through but prevent liquid water from passing through.

[0055] The liquid inlets 306 of the plurality of membrane filaments 601 extend into the bottom space 105 and communicate with the bottom space 105. After the fluid enters the liquid-filling space 104, the fluid flows from top to bottom along the liquid-filling space 104, is collected to the bottom space 105 in the circumferential direction of the bottom space 105, and enters the flow channel through the liquid inlets 306 of the plurality of membrane filaments 601.

[0056] Fluids enter the bottom space 105 from the outer periphery of the bottom space 105, ensuring that the fluids can fully fill the bottom space 105 during flow. In addition, the liquid inlets 306 of the plurality of membrane filaments 601 extend into the bottom space 105, and the injection of fluids into the bottom space 105 and the liquid inlets 306 ensures that each membrane filament 601 is uniformly injected with fluids and that the flow of fluids is smooth.

[0057] In this embodiment, the bottom space 105 is provided with a plurality of ribs 1052, which are circumferentially spaced around the bottom space 105, and a flow guide space is formed between adjacent ribs 1052.

[0068] Hydrogen enters the gas filling interval 201 through the gas filling port 102, and the hydrogen is in a high-pressure state in the gas filling interval 201. The hydrogen in the high-pressure state penetrates into the permeation gap, contacts the outer periphery of the plurality of membrane filaments 601, and permeates into the flow channel of the membrane filament 601 to flow and mix with the fluid flowing in the flow channel to form the hydrogen-containing beverage described above.

[0081] The limiting piece 600 has a plurality of limiting holes, and a plurality of membrane filaments 601 pass through the plurality of limiting holes, so that the adjacent membrane filaments 601 have the permeation gap; the inner side wall of the limiting hole has an abutting section 604 abutting on the membrane filament 601, and the inner side wall of the limiting hole is recessed outward away from the membrane filament 601, forming a plurality of recessed notches 603, which are arranged at intervals along the circumference of the limiting hole, and the abutting section 604 is formed between adjacent recessed notches 603.

[0082] After the hydrogen enters the outer ring interval through the inflation port 102, it enters the inner ring interval through a plurality of gas permeable holes 403, fills the entire permeation section 302, and penetrates into the flow channel of the membrane filament 601; the hydrogen in the high-pressure state drives the middle part of the permeation section 302 to reciprocate during flow, the upper adhesive 401 limits the upper end of the permeation section 302 to be fixed, the lower adhesive 402 limits the lower end of the permeation section 302 to be fixed, and the plurality of limiting pieces 600 fluctuate with the permeation section 302, and limit the permeation gap between adjacent membrane filaments 601.

[0087] The hydrogen in high pressure state penetrates into the multiple axial segments in the middle part of the permeation section 302 through the penetration gap, and the process of hydrogen penetrating into the membrane filaments 601 drives the up-and-down reciprocating deformation of the elastic membrane. The deformation of the elastic membrane drives the pressure change of the hydrogen in the axial segments, so as to make the hydrogen flow reciprocally inside and outside the permeation section 302.

[0088] The reciprocating elastic deformation of the middle piece 602 driven by hydrogen drives the pressure change of the hydrogen in the axial segments, and the hydrogen penetrating into the permeation section 302 realizes the phenomena such as hedging, so that the hydrogen penetrating into the inside of the permeation section 302 is in a reciprocating high pressure flow state, and in the flow process, the hydrogen pressure reciprocally fluctuates, so that the hydrogen can better penetrate into the flow channel of the membrane filaments 601.

Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
