[0023] The technical solution of this utility model will now be described with reference to the accompanying drawings.
[0024] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] Please refer to Figures 1-6 ,
[0026] This invention provides a high-concentration hydrogen-rich liquid hydrogen injection machine. In the prior art, the hydrogen injection efficiency in the liquid hydrogen injection process is relatively low. In order to solve the above-mentioned technical problems, this invention optimizes the structure of the hydrogen injection machine to increase the contact area between hydrogen and liquid, reduce the generation of a large number of bubbles, and further improve the hydrogen injection efficiency.
[0027] The liquid requiring hydrogen injection is usually drinking water or beverage. The hydrogen injection machine provided in this application injects hydrogen into a bottle already containing liquid. The hydrogen injection machine provided in this application mainly includes a shell 100, a cap 200, and a hydrogen storage tank, wherein the hydrogen storage tank serves to store hydrogen gas. The shell 100 and the cap 200 are shown in the figure and are circular in shape. In addition to this shape, they can also be square, etc. The shell 100 is mainly used to hold the bottle containing liquid. In order to achieve the function of securing the bottle, an inner shell layer 130 is also provided on the inner wall of the shell 100. The height of the inner shell layer 130 is lower than the height of the shell 100, and is located near the inner shell layer 130. A fixing bracket 110 is provided near the center. In addition, an installation groove 131 is provided on the top of the inner shell layer 130, and a placement bracket 120 is also provided. An installation block 122 is provided on the side of the placement bracket 120 facing the inner shell layer 130. The installation block 122 can be inserted into the installation groove 131, so that the placement bracket 120 can be inserted into the inner shell layer 130. Through the joint action of the fixing bracket 110 and the placement bracket 120, the bottle body is stabilized. By using the cooperation of the installation block 122 and the installation groove 131, the placement bracket can be removed from the inner shell layer 130, thereby facilitating the overall replacement and improving the replacement efficiency.
[0028] In order to accommodate the bottles, insertion holes 121 are provided on the mounting frame 120 and the fixing frame 110, and a retaining ring is provided on the outer peripheral wall of the insertion hole 121, which also serves to help stabilize the bottles. As shown in the figure, in order to improve the efficiency of the hydrogen injection process, there are multiple insertion holes 121 to facilitate the placement of multiple bottles.
[0029] The cover 200 is located above the housing 100. The cover 200 is equipped with an air inlet 320. The structure of the cover 200 is described in detail below. The cover 200 includes a cover plate 210. An outer cover ring 220 and an inner cover ring 230 are provided on the edge of the cover plate 210. A gap is left between the outer cover ring 220 and the inner cover ring 230 to allow the top of the housing 100 to be placed in the gap. In order to achieve a certain sealing effect, a rubber ring layer (not shown in the figure) is also provided on the inner wall of the outer cover ring 220 and the outer wall of the inner cover ring 230. When the housing 100 can be embedded between the inner cover ring 230 and the outer cover ring 220, the rubber ring layer plays a certain sealing role and reduces the occurrence of air leakage.
[0030] The cover plate 210 is also provided with a cover hole 240, which corresponds to the insertion hole 121. A hydrogen injection tube 300 is installed on the cover hole 240. The hydrogen injection tank includes a tube body 310 and an air inlet 320. The air inlet 320 is tightly connected to the cover hole 240. The air inlet 320 includes an air inlet body 321. A pressure plate 322 extends outward from the top of the air inlet body 321, and an insert plate 323 extends outward from the middle of the air inlet body 321. Near the bottom of the air inlet body 321... The part also extends outward with a cap ring 324. A tube 310 is fitted over the bottom of the air intake body 321. To better accommodate the air inlet nozzle 320, a mounting ring groove 250 is provided at the bottom of the cover plate 210. This mounting ring groove 250 has an opening, with a pressure plate 322 positioned at the top of the cover plate 210, an insert plate 323 positioned within the mounting ring groove 250, and a cap ring 324 positioned at the bottom of the mounting ring groove 250 and engaging with the bottle opening on the mounting bracket 120. The air inlet nozzle 320 ensures a tight connection between the hydrogen injection tube 300 and the cover plate 210.
[0031] To enable efficient injection of hydrogen gas into the liquid within the bottle, reduce air bubbles during injection, and improve injection efficiency, a diffusion assembly 330 is provided on the tube body 310. Multiple diffusion assemblies 330 can be provided on the tube body 310, as shown in the figure (three are evenly distributed at intervals). Each diffusion assembly 330 includes a fixing upper ring 331 and a fixing lower ring 332 fitted around the outer periphery of the tube body 310, with mounting grooves 131 formed on the fixing upper ring 331 and the fixing lower ring. It also includes several isosceles trapezoidal mounting pieces 333. Only four are shown in the diagram, but it is recommended to set more than eight in actual production. The ends of the mounting plates 333 are respectively installed on the upper fixing ring 331 and the lower fixing ring 332. A diffuser is also provided between two adjacent mounting plates 333, and a hydrogen outlet hole 311 is opened at the corresponding position on the tube body 310. The hydrogen outlet hole 311 is located between two adjacent mounting plates 333. The diffuser is a thin membrane made of porous material. The mounting plates 333 play a role in fixing and supporting. In addition, the diffuser has a small pore size of about 1-3 μm, which allows hydrogen to be output from it towards the liquid in the bottle.
[0032] Because the mounting plate 333 has an isosceles triangular trapezoidal structure, the hydrogen gas can be discharged in multiple directions, such as upward, downward, or forward, when it is discharged outward. Furthermore, due to the support of the mounting plate 333, the hydrogen gas preferentially enters the space enclosed by the mounting plate 333 and the diffuser, reducing pressure and thus reducing the generation of bubbles. The diffuser is evenly arranged outward, which allows it to output hydrogen gas evenly, thereby achieving uniform distribution of hydrogen gas in the liquid and improving the efficiency of hydrogen injection.
[0033] The workflow of this utility model is as follows:
[0034] The liquid-filled bottle is placed inside the housing 100 via the mounting bracket 120 and the fixing bracket 110. The cap 200 with the hydrogen filling tank is then placed on the housing 100. The hydrogen storage tank is then opened to allow hydrogen gas to flow from the pipe into the tube 310 and finally be output outward through the diffuser. This structure can evenly distribute hydrogen gas, reduce the generation of bubbles, and thus improve the utilization rate and efficiency of hydrogen filling.
[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
