A pressurizing and mixing mode: after water is filled in the closed container, hydrogen is supplied to the water through the hydrogen production device and then dissolved in the water under certain pressure for mixing. 3. Venturi tube and jet flow mixing mode: the hydrogen dissolution is performed by supplying hydrogen gas to the bypass while supplying water into the venturi. 4. And (3) combining a hollow fiber membrane hydrogen dissolving mode: and supplying water and hydrogen to the hollow fiber membrane filter element, and mixing the hydrogen and the water to dissolve the hydrogen by utilizing the small holes of the hollow fiber membrane and the formed certain pressure. The preparation method has the following defects: 1. since the saturated hydrogen-dissolved amount in water at normal pressure was 1.6ppm, the effect of supersaturation was not obtained. 2. The pressurized mixing mode can produce a super-saturation effect after pressurization, but the requirement on a mixing container is high due to the risk of overhigh pressure, and continuous water outlet cannot be realized only by taking a certain amount of water every time. 3. The venturi and the jet flow mode are low in hydrogen dissolving efficiency, a large amount of gas is wasted in the hydrogen dissolving process, and the cost is relatively high because the gas supply of the large-volume hydrogen production equipment is needed to achieve the saturation effect. 4. The hydrogen dissolving mode of the hollow fiber membrane cannot reach the hydrogen dissolving content of the technology, the cost of the gas supply equipment is relatively high, and the hollow fiber membrane belongs to consumable materials and needs to be replaced regularly.

In the traditional production and preparation process, when the pressure in the mixer is higher in the mixing process, the direct gas supply needs the gas transmission pressure of the electrolytic cell to be greater than the pressure in the mixer or avoids the water supply process for gas transmission, so that a large-gas-amount gas-generating device is needed for rapidly generating gas. This application can produce gas at the water supply in-process incessant and carry out reserve in advance through setting up the gas collector, thereby compares direct gas supply mode and can select the gas production device that the gas production is littleer and reduce cost.

The first valve body, the second valve body, the third valve body, the fourth valve body, the fifth valve body and the seventh valve body are all normally closed electromagnetic valves, and the sixth valve body is a normally open electromagnetic valve, and the working process of the invention comprises the following steps:

the first step is as follows: and opening the liquid pump to supply water, opening the third valve body and the first valve body, closing the sixth valve body, enabling water flow to enter the air cavity from the bottom of the gas collector after passing through the third valve body, and discharging the air in the gas collector from the top of the gas collector and through the first connecting pipe, the first valve body and the second connecting pipe and then from the waste discharge pipe until the gas collector is in a full water state. Because the exit of electrolysis trough is equipped with first check valve, and the export of gas collector is equipped with the second check valve, so water can only be followed the second check valve and discharged through first valve body, and above-mentioned process can be with the inside air of gas collector water evacuation, avoids hydrogen to get into the back mixed air and causes the purity not enough, improves and mixes the hydrogen effect.

After the air cavity of the gas collector is full of water, the third valve body is closed, the fifth valve body, the first valve body and the sixth valve body are opened, water supply is continued, water flow enters the mixing cavity from the bottom of the mixer through the fifth valve body, and air in the mixer is discharged from the top of the mixer, through the first valve body and the waste discharge pipe until the mixer is in a full water state.

The second step is that: and after the mixer is in a full water state, the fifth valve body and the first valve body are closed, the sixth valve body is opened, and water supply is stopped simultaneously. Then the electrolytic cell is started to work to generate hydrogen, the hydrogen is injected from the top of the gas collector, and because the sixth valve body is in an open state, water in the gas collector can be discharged from the waste discharge pipe through the sixth valve body from the bottom due to gas entering, and when the water is emptied, the gas supply is stopped, and at the moment, all the hydrogen is in the gas collector. The specific emptying time is determined by the gas production of the electrolytic cell, the gas supply time can be set according to the gas production and the size of the gas collector, a liquid level sensor and the like can be arranged in the internal capacity of the gas collector to set the gas supply time, a visual window can be arranged on the gas collector to judge the liquid level, or the gas supply time can be set after the water contained in the gas collector is discharged.

The third step: after stopping the air feed, the third valve body and the seventh valve body are opened, the sixth valve body is closed, water supply is started, and water flow enters the mixing cavity for pushing the internal hydrogen into the mixer from the top of the gas collector from the bottom of the gas collector through the third valve body. The pressure of the water in the mixing cavity is increased due to the entrance of the top gas, the constant pressure valve is automatically opened to discharge the water when the opening pressure of the constant pressure valve is reached, and the water is discharged through the seventh valve body. Then the third valve body, the seventh valve body are closed, the sixth valve body is opened, and the water supply is stopped.

Further, if the pressure of the gas in the mixer is desired to be increased, the second step and the third step can be repeated, that is, the second step is executed again after the water supply is stopped, then the electrolytic cell is opened to work and drain the water, then the gas is stopped, the third valve body, the seventh valve body are opened, the sixth valve body is closed, the water is supplied to inject the water into the mixer from the gas collector, and the gas can be compressed to form a larger gas storage amount and a certain pressure in the mixer by repeating the steps, and the mixing effect is better under the condition that the internal gas pressure is higher. The mixer can also be shaped to extend the hydrogen and water mixing time by matching the spray pattern of the atomizer. In the process of water production, more water can be generated by mixing larger gas storage amount, the frequency of gas supplement is reduced, for example, the gas amount of the gas collector is added repeatedly for three times, and gas can be added after three parts of water are produced.

Further, after the third step is completed, hydrogen can be continuously delivered through the second step to store the hydrogen in the gas collector for being replenished when needed next time.

The fourth step: hydrogen-rich water is made by mixing, the second valve body and the fourth valve body are opened, and the liquid pump is started to supply water. Rivers carry out the gas-liquid mixture from the mixing chamber of blender top entering blender through the second valve body, and when the pressure in the mixing chamber reached constant pressure valve cracking pressure, hydrogen-rich water flows through fourth valve body and discharging pipe discharge, and the end of discharging pipe sets up hydrogen-rich water collecting vessel.

Furthermore, when the hydrogen-rich water is prepared to a certain amount, the gas amount in the mixer is reduced due to consumption, the gas stored in the gas collector can be conveyed into the mixer for filling in a third step, then the electrolysis bath is started again to generate gas for supplementing the gas collector, the electrolysis bath gas generation can be started to carry out gas filling by monitoring the water making amount through a flowmeter, and the water level change can be sensed through a liquid level sensor in the mixer or a window on a container for judgment.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
