Background

A large number of animal experiments and clinical researches prove that the hydrogen has definite or potential treatment value on 68 important human diseases such as cerebral ischemia, metabolic syndrome, diabetes, arteriosclerosis, senile dementia, fatty liver, liver cirrhosis, rheumatoid arthritis, asthma, uremia, noise deafness, acute pancreatitis, side effects of tumor radiotherapy and chemotherapy and the like. Interestingly, scholars of the university of agriculture in Nanjing, China found that hydrogen gas subjects improve the disease resistance of plants and put forward a new concept of 'hydrogen fertilizer'. Conventional clinical therapeutic drugs all have side effects, and long-term drug therapy itself can cause many health problems. Hydrogen therapy provides an ideal choice for some patients as a safe and long-term treatment. In addition, the hydrogen has high chemical stability and short action time, and does not react with other medicines, so the compound can be used as an ideal combined treatment mode. In general, hydrogen is used in both health and disease treatment.

The hydrogen absorption is very active and obvious for the sub-health of people and the rehabilitation of a plurality of diseases, so the hydrogen absorption becomes a new fashion for people to pursue healthy life in the future, and simultaneously, the hydrogen absorption also has the positive effect on the aspect of hydrogen medical treatment.

However, the hydrogen production by water electrolysis can generate heat in the electrolytic reaction process, and the temperature of the hydrogen production device by water electrolysis can be higher and higher along with the reaction, thus seriously affecting the efficiency of the hydrogen production reaction.

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.

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 inventors' experiments, 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: the heat conduction efficiency is best when the ratio is 1: 1-5-3.5.

When the second phase change chamber 3 is heated, the second phase change material 33 absorbs a large amount of heat, a part of the second phase change material 33 changes from a solid state to a liquid state, and when the second phase change material 33 contacts a wall body having a lower temperature, which is in contact with the first phase change chamber 2, releases the heat to change into a solid state, so that the heat is conducted to the first phase change chamber 2.

The cell 10 has its optimum operating temperature range, typically between 35 c and 85 c, beyond which efficiency, stability, and life are affected. The efficiency of the cell 10 is also reduced when the temperature is below the optimum temperature, which may cause the cell 10 to fail to start properly for a short period of time. In addition, the electrolytic cell 10 is accompanied by heat generation during operation, and the heat cannot be rapidly dissipated in a short time, so that the temperature inside the electrolytic cell 10 is increased, and the high temperature not only affects the operation efficiency, stability and reliability of the electrolytic cell 10, but also shortens the service life of the electrolytic cell 10.

The phase change cavity is internally provided with a phase change material which can change phase when being heated or cooled, and the phase change material can absorb or release heat when changing phase, so that high-efficiency heat conduction is realized. On the other hand, when the phase change cavity is heated or cooled, the phase change material is subjected to phase change, the phase change cavity can realize heating or cooling of the heat exchange cavity 1, and reverse heat conduction is realized. The heat exchange system arranged on the electrolysis device 1-1 of the hydrogen-rich water bathing system comprises the heat exchange cavity 1 and the phase change cavity, wherein the phase change cavity is internally provided with the phase change material, and heat exchange is carried out by the heat absorption and heat release principle of the phase change material during phase change, so that the heat exchange efficiency is high, the hydrogen production efficiency, the stability and the reliability of the electrolysis device 1-1 are improved, the service life of the electrolysis device 1-1 is prolonged, and the production efficiency of the hydrogen-rich water is improved.

In a preferred embodiment, the hydrogen-oxygen mixed breathing machine further comprises a first filtering device 1-2, wherein the hydrogen pipe 3-13 and the oxygen pipe 1-12 are both communicated with the first filtering device 1-2, the outlet of the first filtering device 1-2 is communicated with the water tank 3-1, and the primary filtering device 1-2 is used for filtering impurities in the hydrogen and the oxygen.

In another preferred embodiment, the oxygen pipe 1-12 is communicated with a second filtering device 1-3, the hydrogen pipe 3-13 is communicated with a third filtering device 1-4, and the air outlets of the second filtering device 1-3 and the third filtering device 1-4 are both communicated with the water tank 3-1.

In a preferred embodiment, the water tanks comprise a first water tank 3-11 and a second water tank 3-12, the first water tank 3-11 and the second water tank 3-12 are both communicated with the electrolysis device 1-1, the air outlet of the second filtering device 1-3 is communicated with the first water tank 3-11, and the air outlet of the third filtering device 1-4 is communicated with the second water tank 3-12. The water in the oxygen falls into the first water tank 3-11, the water in the hydrogen falls into the second water tank 3-12, and the water in the first water tank 3-11 and the second water tank 3-12 participates in the electrolysis reaction of the electrolysis device 1-1 again.

In a preferred embodiment, the hydrogen-oxygen mixing respirator also comprises a water quality detection probe 5-5 and a liquid level detection probe 5-6, wherein the water quality detection probe 5-5 and the liquid level detection probe 5-6 are used for detecting the water quality and the liquid level in the water tank 3-1. The electrolyzer 1-1 has requirements for water source, which is pure water or deionized water or redistilled water. The water quality detection device 5-5 is used for detecting the water quality in the water 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 tank 3-1, 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 to the water tank 3-1, certainly, manual water replenishing can also be carried out by arranging a water filling port, and the water tank 3-1 is generally kept at the water level above 2/3. The bathing system also comprises a water supply pump 5-7, wherein the water supply pump 5-7 is used for supplementing water to the electrolysis device, and the water supply pump 5-7 can be automatically controlled by a control circuit to supply water to the electrolysis device. Along with the work of the electrolysis device 1-1, the water in the water tank is less and less, and once the water is short, the electrolysis device is burnt. Therefore, when the water in the water tank 3-1 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 tank 3-1 is in water shortage and the like. In addition, the water feeding pump 5-7 also plays a role in pressurization, is beneficial to increasing the circulation of water in the electrolysis device 1-1 and plays a role in reducing the internal temperature of the electrolysis device 1-1. Of course, if the vertical distance between the outlet of the water tank 3-1 and the water inlet of the electrolyzer 1-1 is large enough to have a certain potential, the water pump 5-7 may not be added when the water in the water tank 3-1 can flow into the electrolyzer 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, when the machine starts, the water feeding pump 5-7 is started, and the water in the water tank 3-1 is started again when reaching a certain temperature (for example, 40 ℃), or the water can be started once in half an hour. If the water feeding pump 5-7 is provided, the check valve 5-10 is not needed, and the check valve 5-10 is used for preventing oxygen in the electrolysis device 1-1 from flowing back to enter the water inlet of the electrolysis device 1-1, so that the water is not favorably flowed in. If the water feeding pump 5-7 is not arranged, the one-way valve 5-10 or the one-way valve 5-10 can be arranged according to the vertical distance between the outlet of the water tank 3-1 and the water inlet of the electrolysis device 1-1, because the situation that oxygen in the electrolysis device 1-1 does not flow out from the oxygen port but enters the water inlet of the electrolysis device 1-1 from the inside of the electrolysis device 1-1 when the electrolysis device 1-1 is started can exist at the beginning, but the phenomenon that the oxygen enters the water inlet of the electrolysis device 1-1 after the electrolysis device 1-1 works for a few minutes basically disappears, and the electrolysis device 1-1 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 electrolytic cell 10 has its optimum operating temperature range, typically between 35 c and 80 c, beyond which efficiency, stability, and life are affected. When the temperature is lower than the optimal temperature, the electrolytic cell 10 cannot be started normally in a short time, the efficiency of the electrolytic cell 10 is also reduced, and as the electrolytic cell 10 works, the water in the water tank is less and less, and once the water is short, the electrolytic cell is burnt out. Therefore, when the water in the water tank 3-1 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 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 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 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, when the machine starts to be started, the water feeding pump 5-7 is started, the water in the water tank 3-1 is started again when the water reaches a certain temperature, such as 40 ℃, or the water is started once after half an hour, generally, when the water temperature is less than 25 ℃, the instant heating module is automatically started. 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 not be arranged according to the vertical distance between the outlet of the water 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 electrolyzed water filtering device 5-3 can filter impurities in the water entering the electrolytic cell 10, and the electrolyzed water filtering device 5-3 can be ion exchange resin or other devices capable of removing anions and cations in the water, such as anion and cation mixed bed resin, so as to remove the impurities in the water and protect the purity of the water source. The temperature probe can be arranged in the water tank 3-1 or on the water supply pipeline 5-1 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 tank 3-1 and the electrolyzed water 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 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 tank 3-1 can be completely removed, a water discharge pipeline is also arranged between the outlet of the water tank 3-1 and the electrolytic water filtering device 5-3 and is used for completely removing the unqualified water in the water 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, the hydrogen gas outlet can also be provided with an electrolyzed water 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.
