Another embodiment is that the gas return line 5-17 is located in front of the hydrogen dissolving communication 2-12, and because the dissolving amount of hydrogen in water is relatively small, part of hydrogen is mixed with oxygen through the gas return line 5-17 before the hydrogen is mixed with drinking water, so that the utilization rate of hydrogen can be improved.

In a preferred embodiment, the oxyhydrogen gas and hydrogen-rich water supply system further comprises a water supply tank 3-1, the water supply tank 3-1 is communicated with the hydrogen production module 1-1 through a water supply pipeline 3-2, the water supply tank 3-1 is used for supplying electrolyzed water to the hydrogen production module 1-1, in addition, the hydrogen production module 1-1 also generates oxygen, and the gas flow passage further comprises an oxygen flow passage 1-12, and the oxygen can flow back to the water supply tank 3-1 through the oxygen flow passage 1-12. The electrolytic cell 10 has a requirement for a water source, which may be pure water or deionized or redistilled water. The water supply tank 3-1 is also internally provided with a water quality detection device 5-5 and a liquid level detection device 5-6. The water quality detection device 5-5 is used for detecting the water quality in the water supply tank 3-1, if the water quality of the water added by a user does not reach the standard, the water quality detection device 5-5 can transmit a signal to a corresponding control circuit, the machine is not started, and the alarm requires the replacement of a water source. The liquid level detection device 5-6 can measure the water level in the water supply tank 3-1, and the liquid level detection device 5-6 can also be connected with a corresponding control circuit to control a corresponding water replenishing pump to replenish water for the water supply tank 3-1, and certainly can also manually replenish water by arranging a water filling port. The tank 3-1 is normally maintained at a water level above 2/3.

The water supply pipeline 3-2 is provided with a filtering device 5-3 and an instant heating module 5-2, and the water supply pipeline 3-2 is also provided with a water supply pump 5-7 or a one-way valve 5-10. The water feeding pump 5-7 is used for supplementing water to the electrolytic cell, and the water feeding pump 5-7 can be automatically controlled by the control circuit to supply water to the electrolytic cell. As the cell 10 operates, less and less water is present in the tank, which in the event of a water shortage will result in the cell burning. Therefore, when the water in the water storage tank 2-1 is lower than a certain set value, such as 1/10 of the whole water tank, the liquid level detection device 5-6 inputs a signal into the control circuit, the machine stops working and gives an alarm (a flash lamp is arranged and flashes), a user is reminded to add water, and the user can check whether the corresponding water feeding pump 5-7 is in failure or whether the water feeding tank 3-1 is in water shortage and the like. In addition, the water feeding pumps 5 to 7 also play a role in pressurization, which is beneficial to increasing the circulation of water in the electrolytic cell 10 and playing a role in reducing the temperature in the electrolytic cell 10. Of course, if the vertical distance between the outlet of the water supply tank 3-1 and the water inlet of the electrolytic cell 10 is large enough to have a certain potential, the water pump 5-7 may not be added when the water in the water supply tank 3-1 can flow into the electrolytic cell with a certain pressure. If the water feeding pump 5-7 is arranged, the water feeding pump 5-7 can be set with interval starting time, the water feeding pump 5-7 is started when the machine starts to be started, and the water in the water feeding tank 3-1 is started again when the water reaches a certain temperature, such as 40 ℃, or the water is started once in half an hour. If the water feeding pump 5-7 is provided, the check valve 5-10 is not provided, and the check valve 5-10 is used for preventing oxygen in the electrolytic cell 10 from flowing back to the water inlet of the electrolytic cell 10, thereby being not beneficial to the inflow of water. If the water supply pump 5-7 is not arranged, the check valve 5-10 can be arranged or the check valve 5-10 can be omitted according to the vertical distance between the outlet of the water supply tank 3-1 and the water inlet of the electrolytic cell 10, because the oxygen in the electrolytic cell 10 does not flow out from the oxygen port but enters the water inlet of the electrolytic cell 10 from the inside of the electrolytic cell 10 when the electrolytic cell 10 starts to start, but the phenomenon that the oxygen enters the water inlet of the electrolytic cell 10 after the electrolytic cell 10 works for a few minutes basically disappears, and the electrolytic cell 10 works normally. Therefore, the feed pump 5-7 and the check valve 5-10 may be provided separately or neither depending on the design of the machine system.

The filtering means 5-3 may filter impurities in the water introduced into the electrolytic cell 10, and the filtering means 5-3 may employ ion exchange resin or the like. The temperature probe can be arranged in the water supply tank 3-1 or on the water supply pipeline 3-2 and is used for detecting the temperature of a water source, because the low temperature or the high temperature is unfavorable for the working efficiency and the service life of the electrolytic cell 10, when the water temperature is low or even freezes, the temperature probe transmits a low-temperature signal to a corresponding control circuit, the machine is not started, the instant heating module 5-2 is immediately started at the moment, ice is melted until the water temperature reaches about 20 ℃, the machine is started to work, and the instant heating module 5-2 stops heating at the moment.

In addition, an electromagnetic valve and a drain pipeline can be arranged between the outlet of the water supply tank 3-1 and the filtering device 5-3, so as to protect the electrolytic cell 10 from being polluted by unqualified water sources. The purpose of the solenoid valve is to protect the electrolytic cell 10 from contamination by the rejected water source, because the rejected water flows into the electrolytic cell 10 even though the machine is not being started up when the user adds the rejected water to the water supply tank 3-1. When the water quality detection device 5-5 detects that the added water is unqualified (such as tap water), the electromagnetic valve is closed to prevent the unqualified water from flowing into the electrolytic cell 10, the machine alarms to require water source replacement, and in order to ensure that the unqualified water in the water supply tank 3-1 can be completely removed, a water discharge pipeline is also arranged between the outlet of the water supply tank 3-1 and the filter device 5-3 and is used for completely removing the unqualified water in the water supply tank 3-1 and preventing the electrolytic cell 10 from being polluted. In order to prevent the hydrogen gas from coming out of the electrolytic cell 10 from carrying a small amount of metallic impurities, a filtering device 5-3 may also be provided at the hydrogen gas outlet.

In addition, the whole system is also provided with an intelligent AI chip and an Internet of things control module (not shown), the intelligent AI chip can realize the conversation between a person and a machine, for example, a user can inquire the machine: how much the cell 10 is at temperature? How many hours are the cell 10 in operation? How long is the cell 10 still in service? How much water is left in the water supply tank 3-1? How does the water quality in the water supply tank 3-1? How much hydrogen rich water (hydrogen rich water) is concentrated? The machine can automatically voice-broadcast the answers. The thing networking control module combines together with APP, can look over the condition of machine on APP, like 10 temperature of electrolytic cell, 10 operating time of electrolytic cell, supply tank 3-1 in have how much water, the quality of water in the supply tank 3-1, hydrogen-rich water (hydrogen-rich water) concentration isoparametric.
