In a preferred embodiment, the hydrogen breathing machine 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 can also generate oxygen, the gas flow channel further comprises an oxygen flow channel 1-12, and the oxygen can flow back to the water supply tank 3-1 through the oxygen flow channel 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, the liquid level detection device 5-6 can also be connected with a corresponding control circuit to control the corresponding water replenishing pump 5-12 to replenish water for the water supply tank 3-1, the hydrogen breathing machine also comprises the water replenishing pump 5-12 used for supplying water to the water supply tank 3-1, the water replenishing pump 5-12 can be connected with a corresponding pure water and deionized water interface, automatic water replenishing for the water supply tank 3-1 can be realized through a corresponding control system, certainly, manual water replenishing can also be realized through arranging a water filling port, and the water supply tank 3-1 is generally kept at the 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 drinking water 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 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 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 flowing out of the electrolytic cell 10 from carrying a small amount of metal impurities, a filtering device 5-3, which can be ion exchange resin or other devices capable of removing metal ions in water, such as anion and cation mixed bed resin, can also be arranged 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 temperature of the electrolytic cell 10 is, how many hours the electrolytic cell 10 works, how long the service life of the electrolytic cell 10 is, how much water is in the water supply tank 3-1, how much the water quality in the water supply tank 3-1 is, and how much the flow and pressure of hydrogen in the air suction pipeline are, the machine can automatically broadcast and answer by voice, and the machine is combined with the control module and the APP of the Internet of things to realize automatic control or manual voice control and the like. The condition of the machine can be checked on APP, such as the temperature of the electrolytic cell 10, the working time of the electrolytic cell 10, the amount of water in the water supply tank 3-1, the water quality in the water supply tank 3-1 and other parameters. The corresponding solenoid valve can also be controlled, for example, when the light is detected, the power supply is automatically closed, the electrolysis reaction is stopped, and the supply of hydrogen is cut off, so that explosion is prevented.

The phase transition temperature is the temperature at which the phase change material changes from one physical form to another, for example, when the phase change material is water, the phase transition temperature at which the phase change material changes from a liquid state to a gas state under normal atmospheric pressure is 100 ℃. Because in the heat conduction process, the first phase change chamber 2 and the second phase change chamber 3 have a temperature difference, through the phase change material that sets up different phase change temperatures therein, can guarantee that two phase change chambers can both satisfy phase change temperature. The projection area of the heat-conducting part of the first phase change cavity 2 and the heat exchange cavity on the horizontal plane is 0.01 square meter to 50 square meters, and particularly, the projection area of the heat-conducting part of the first phase change cavity 2 and the heat exchange cavity on the horizontal plane is 0.1 square meter, 0.5 square meter, 1 square meter, 5 square meters, 8 square meters or 10 square meters. The vertical height of the first phase change cavity 2 and the vertical height of the second phase change cavity 3 are 0.5-300 mm; specifically, the vertical height of the first phase change cavity 2 and the vertical height of the second phase change cavity 3 are 1mm, 5mm, 10mm, 20mm, 50mm, 70mm or 90 mm. If the projection area of the second phase change cavity 3 and the heat exchange cavity 1 on the horizontal plane is too large, the height of the phase change cavity is very low, the difference between the high-temperature part and the low-temperature part of the phase change material is not obvious, and the heat exchange effect is influenced; if the projection area of the second phase change chamber 3 and the heat exchange chamber 1 on the horizontal plane is too small, the heat conduction area is too small, the heat conduction efficiency is too low, and the heat exchange efficiency is not favorable. In another preferred embodiment, the phase change cavities include a first phase change cavity 2 and a second phase change cavity 3, the first phase change cavity 2 is located between the heat exchange cavity 1 and the second phase change cavity 3, the first phase change cavity 2 and the heat exchange cavity 1 can directly conduct heat to each other, the first phase change cavity 2 and the second phase change cavity 3 can also directly conduct heat to each other, and phase change materials with different phase change temperatures are respectively arranged in the first phase change cavity 2 and the second phase change cavity 3. The phase transition temperature is the temperature at which the phase change material changes from one physical form to another, for example, when the phase change material is water, the phase transition temperature at which the phase change material changes from a liquid state to a gas state under normal atmospheric pressure is 100 ℃. Because in the heat conduction process, the first phase change chamber 2 and the second phase change chamber 3 have a temperature difference, through the phase change material that sets up different phase change temperatures therein, can guarantee that two phase change chambers can both satisfy phase change temperature. The projection area (square meter) of the heat conducting part of the first phase change cavity 2 and the heat exchange cavity 1 on the horizontal plane is as follows: the height of the first phase change cavity 2 vertical to the horizontal plane is (mm) 0.01-100: 1, specifically, the projected area of the heat conductive part of the first phase change chamber 2 and the heat exchange chamber 1 on the horizontal plane is as follows: the height of the first phase change cavity 2 vertical to the horizontal plane is 0.1:1 or 1:1, or 10:1 or 50:1 or 90: 1. The applicant has found through experiments that the heat conduction effect of the gas-liquid phase change material is better when the proportion value is in the range of 1-10:1, and the effect is optimal particularly when the proportion value is 5: 1. If the projection area of the heat-conducting part of the first phase change cavity 3 and the heat exchange cavity 1 on the horizontal plane is too large, the height of the phase change cavity is very low, the difference between the high-temperature part and the low-temperature part of the phase change material is not obvious, and the heat exchange effect is influenced; if the projection area of the heat-conducting part of the first phase change chamber 3 and the heat exchange chamber 1 on the horizontal plane is too small, the heat-conducting area is too small, the heat-conducting efficiency is too low, and the heat exchange efficiency is not favorable.

In a preferred embodiment, a first phase change material 23 is disposed in the first phase change chamber 2, a second phase change material 33 is disposed in the second phase change chamber 3, and a phase change temperature of the first phase change material 23 is lower than a phase change temperature of the second phase change material 33. When heat is conducted from the second phase change cavity 3 to the first phase change cavity 2, the temperature of the first phase change cavity 2 is lower than that of the second phase change cavity 3, phase change can be achieved by phase change materials in the two phase change cavities, and efficient heat conduction is achieved. The ratio of the phase transition temperature of the first phase change material 23 to the phase transition temperature of the second phase change material 33 is: 1:1-5-3.5, specifically, the ratio of the phase transition temperature of the first phase change material 23 to the phase transition temperature of the second phase change material 33 is: 1:1.5 or 1:2 or 1:2.5 or 1:3 or 1: 3.5. More specifically, the method is described further. If the phase change temperature of the first phase change material 23 is too different from the phase change temperature of the second phase change material 33, the temperature transferred by the first phase change material 23 may not change the state of the second phase change material 33, the heat transferred by the second phase change material 33 to the first phase change material 23 may not change the state of the first phase change material 23, and the heat absorption and release are seriously affected without changing the state of the phase change material, resulting in low heat conduction efficiency. If the phase change temperature difference between the first phase change material 23 and the second phase change material 33 is small, the significance of arranging two phase change cavities is lost, and quick and efficient heat exchange cannot be realized. Through the utility model human experiment, the phase transition temperature of first phase change material 23 with the phase transition temperature of second phase change material 33 compares and is: the heat conduction efficiency is best when the ratio is 1: 1-5-3.5.
