Description

Technical Field

[0001] The present application relates to the technical field of hydrogen production, and more specifically, to a hydrogen generator and a working method thereof. Background Art

[0002] The hydrogen generator produces high-purity oxygen and hydrogen through electrolysis of direct current. Hydrogen can be used in fuel cells, fuel gas, reaction gas and gas chromatograph. In addition, literature shows that hydrogen molecules have positive effects on cell apoptosis and abnormal vascular proliferation due to their anti-free radical and selective antioxidant effects. Therefore, in order to facilitate the use of hydrogen for disease prevention and post-disease rehabilitation, hydrogen respirators came into being. As an inhalation medical device, one type of hydrogen respirator uses proton exchange membrane water electrolysis (PEME) to produce hydrogen, that is, purified water that meets the requirements is sent to the electrolyzer. Under the action of direct current, pure water produces hydrogen on the cathode side of the electrolyzer and oxygen on the anode side of the electrolyzer. The pure hydrogen machine only collects hydrogen, and the hydrogen-oxygen machine collects it together with oxygen. The pure hydrogen machine generally releases oxygen into the atmosphere, and the hydrogen is inhaled into the body through a nasal cannula.

The term "plurality" shall mean two or more.

[0067] Before introducing the technical solution of the present application, the application scenario of the technical solution of the embodiment of the present application is first introduced: during the electrolysis reaction, the water in the oxygen generating tank will move to the hydrogen generating tank, causing the water level of the oxygen generating tank to gradually become lower than the water level of the hydrogen generating tank. For example, in the disclosed technologies such as CN108179435A, there is a lack of linkage between the two water storage devices of the hydrogen generator, and there is room for improvement to further improve the utilization efficiency of pure water.

[0068] Based on the above considerations, according to the first aspect of the present application, there is provided a Figure 1-Figure 5 The hydrogen generator 100 shown comprises:

[0069] The electrolyzer 30 includes a hydrogen generator 31 and an oxygen generator 32. The hydrogen generator 31 is provided with a hydrogen output port 311 for outputting hydrogen. The oxygen generator 32 is provided with a gas output port for outputting oxygen and water vapor. The oxygen generator 32 is provided with an oxygen generator water inlet. In some embodiments, the structure of the electrolyzer 30 may also include: an anode plate, a proton exchange membrane, and a cathode plate. The proton exchange membrane divides the electrolyzer 30 into a hydrogen generator 31 and an oxygen generator 32 longitudinally. The anode plate is arranged in the oxygen generator 32, and the cathode plate is arranged in the hydrogen generator 31. For example, in some embodiments: the gas output port can be arranged at the upper part of the oxygen generator 32, and oxygen and water vapor are output to the oxygen generator 32 through the gas output port. The oxygen generator water inlet is arranged at the lower part of the oxygen generator 32, and the purification water tower 80 supplies water to the oxygen generator 32 through the oxygen generator water inlet.

[0070] A water supply member 10 , wherein a water storage area of ​​the water supply member 10 is connected to the hydrogen output port 311 through a pipeline.

[0071] A purification water tower 80 is provided with a gas input port 81, which is connected to the gas output port of the oxygen generating tank 32 and is used to receive oxygen and water vapor generated by the oxygen generating tank 32, wherein oxygen is discharged from an oxygen outlet 84 provided in the purification water tower 80, wherein water vapor is condensed to supplement the water of the purification water tower 80; the purification water tower 80 is provided with a purification water tower outlet 82, which is connected to the oxygen generating tank water inlet of the oxygen generating tank 32 through a pipeline, and a water purification element is provided inside the purification water tower 80, and the water purification element purifies the water inside the purification water tower 80 and supplies water to the oxygen generating tank 32 through the purification water tower outlet 82 and the oxygen generating tank water inlet. For example, in a specific embodiment, the water purification element is a water purification resin provided inside the purification water tower 80, and the water purification resin can reduce the total amount of dissolved solids in the water contained inside the purification water tower 80, thereby increasing the service life of the electrolytic cell 30. For example, in some embodiments: the gas input port 81 is disposed at the upper portion of the purification water tower 80, the gas input port 81 at the upper portion of the purification water tower 80 is connected to the upper gas output port at the oxygen generating tank 32 to receive the oxygen and water vapor generated by the oxygen generating tank 32, and the oxygen outlet 84 disposed at the upper portion of the purification water tower 80 discharges the oxygen therein. The purification water tower water outlet 82 is disposed at the lower portion of the purification water tower 80 to facilitate the water supply to the oxygen generating tank 32 under the action of gravity.

[0072] The water supply part 10 is connected to the purified water tower 80 through a first water replenishment pipeline, and a water pump 60 is arranged on the first water replenishment pipeline. The control module is connected to the electrolyzer 30 and the water pump 60 to control the working state of the electrolyzer 30 and the water pump 60 respectively. It can be understood that the control module controls the working state of the electrolyzer 30, and also controls the working state of the hydrogen generator 31 and the oxygen generator 32. When the measured water level in the purified water tower 80 is lower than the preset water level range, the control module controls the water pump 60 to start so that the water supply part 10 supplies water to the purified water tower 80 through the first water replenishment pipeline and the purified water tower water inlet 83 of the purified water tower 80; when the measured water level in the purified water tower 80 is higher than the preset water level range, the control module controls the water pump 60 to stop so that the water supply part 10 stops supplying water to the purified water tower 80. In some embodiments, a water level sensor is disposed inside the water purification tower 80 , and the water level sensor is used to detect the water level inside the water purification tower 80 to obtain the actual measured water level.

[0073] In the present application, the control module may be a control circuit board, or a microcontroller (MCU) on the control circuit board.

[0074] The water supply component 10 is connected to a mixed gas output pipeline Q, and the mixed gas output pipeline Q is connected to an air input pipeline M for inputting air. A hydrogen absorption port 23 is provided at the end of the mixed gas output pipeline Q. The hydrogen generated by the hydrogen generating tank 31 passes through the water storage area of ​​the water supply component 10 and is mixed with the air input by the air input pipeline M to form a mixed gas. The mixed gas is output from the hydrogen absorption port 23 through the mixed gas output pipeline Q.

[0075] In the present application, the water purification tower 80 is connected to the oxygen generating tank 32, and the water supply component 10 is connected to the water purification tower 80 through a first water replenishment pipeline. With such a configuration, when the measured water level in the water purification tower 80 is lower than the preset water level range, the water pump 60 starts to make the water supply component 10 supply water to the water purification tower 80 through the first water replenishment pipeline; when the measured water level in the water purification tower 80 is higher than the preset water level range, the water pump 60 stops to make the water supply component 10 stop supplying water to the water purification tower 80. In this way, the present application provides a design in which the water supply component 10 intermittently supplies water to the water purification tower 80, and there is no need to manually add water when the water purification tower 80 is short of water, thereby reducing the difficulty of operating the hydrogen generator 100 of the present application. In addition, since the water supply component 10 intermittently supplies water to the water purification tower 80, it can be as follows. Figure 1 As shown, the water purification tower 80 is arranged inside the hydrogen generator 100 and the manual water injection port design of the water purification tower 80 in the prior art is omitted, which improves the simplicity of the hydrogen generator 100 of the present application. Figure 3 As shown, the water supply part 10 is arranged outside the hydrogen generator 100, and its upper and lower parts are detachable, so that it is convenient to manually add water to the water supply part 10. The injected water is pure water, which can prevent the electrolytic cell 30 from producing minerals harmful to the human body, and also improve the service life of the electrolytic cell 30, and also improve the purity of hydrogen in the hydrogen generating cell 31.

[0076] In the present application, the oxygen generating tank 32 is provided with an oxygen generating tank water inlet at the bottom, and the purification water tower 80 is provided with a purification water tower water outlet at the bottom, and the purification water tower water outlet is connected with the oxygen generating tank water inlet through a pipeline. With such a design, when water stops flowing between the oxygen generating tank 32 and the purification water tower 80, the water surface of the oxygen generating tank 32 and the water surface of the purification water tower 80 are on the same horizontal plane, achieving the purpose of regulating the water volume and water surface in the oxygen generating tank 32 through the purification water tower 80, without the need to set a corresponding detector in the oxygen generating tank 32, and saving space in the oxygen generating tank 32.

[0077] In this application, if Figure 5As shown, the water level sensor, the water pump 60 and the microprocessor can be directly or indirectly connected. The water level sensor transmits the measured water level in the water purification tower 80 to the microprocessor. The microprocessor compares the measured water level with the preset water level range to choose to start and stop the water pump 60, thereby realizing automatic water supply from the water supply component 10 to the water purification tower 80.

[0078] In some embodiments, the water storage area of ​​the water supply component 10 is connected to the hydrogen generating tank 31, so that the hydrogen generated by the hydrogen generating tank 31 passes through the water storage area and is released into the gas mixing area of ​​the water supply component 10, and the gas mixing area is located above the water storage area; the water storage area of ​​the water supply component 10 is also connected to the air input pipeline M, so that the air input by the air input pipeline M passes through the water storage area and is released into the gas mixing area of ​​the water supply component 10, and the air and hydrogen are mixed in the gas mixing area and then output from the hydrogen absorption port 23 through the mixed gas output pipeline Q. The hydrogen generated by the hydrogen generating tank 31 and the air input from the air input pipeline M can be mixed more fully in the gas mixing area, and the change of hydrogen concentration in the mixed gas output pipeline Q is relatively stable. For example, when the user adjusts the pressure to inhale a higher concentration of hydrogen, the higher concentration of hydrogen is mixed with air in the gas mixing area and then enters the mixed gas output pipeline Q. As the higher concentration of hydrogen in the gas mixing area increases, the hydrogen concentration in the mixed gas transported by the mixed gas output pipeline Q gradually increases to the hydrogen concentration value set by the user, which helps to reduce the discomfort caused to the user by the sudden change of hydrogen concentration. In the present application, the hydrogen output port 311 should be located above the water surface in the hydrogen generating tank 31, and the position of the hydrogen output port can be adjusted based on the set water level. For example, in Figure 1 In the illustrated embodiment, the hydrogen output port 311 is disposed at the lower portion of the hydrogen generating tank 31 . In other embodiments, the hydrogen output port 311 may also be disposed at the upper portion of the hydrogen generating tank 31 .

[0079] In some embodiments, Figure 3-Figure 5 As shown, the hydrogen generator 100 further includes an air pump 52. Figure 4 As shown, the air pump 52 is arranged in the air input pipeline M, and the air pump 52 delivers external air into the air input pipeline M and the mixed gas output pipeline Q; the control module is connected to the air pump 52 to control the working state of the air pump 52. The air flow rate can be adjusted by the air pump 52, so that the volume ratio of hydrogen to air can be adjusted. For example, in some specific embodiments, hydrogen accounts for about 2% of the mixed gas, which is lower than the range of hydrogen combustion and explosion of 4% to 74%, ensuring the safety of inhaling hydrogen. In some embodiments of the present application, hydrogen accounts for about 2% of the mixed gas output by the hydrogen generator 100. Setting the air pump 52 in the air input pipeline M can effectively ensure the air flow rate and improve safety performance.

[0080] The working states of the electrolyzer 30, water pump 60 and air pump 52 include: start, stop and power level. For example, the hydrogen production rate of the electrolyzer 30 is changed by the current level, thereby changing the hydrogen output per unit time, thus changing the proportion of hydrogen in the mixed gas.

[0081] In some embodiments, Figure 4 As shown, the hydrogen generator 100 also includes a first air pressure sensor 51, which is arranged on the air input pipeline M and is used to detect the air pressure value of the air in the air input pipeline M. The first air pressure sensor 51 is connected to the control module, and the control module obtains the air pressure value and controls the working state of the electrolyzer 30 or / and the air pump 52 based on the preset air pressure range and the air pressure value. In one embodiment, the control module controls the working state of the electrolyzer 30 based on the preset air pressure range and the air pressure value. In another embodiment, the control module controls the working state of the air pump 52 based on the preset air pressure range and the air pressure value. In yet another embodiment, the control module controls the working state of the electrolyzer 30 and the working state of the air pump 52 based on the preset air pressure range and the air pressure value. Specifically, for example, when the air pump 52 extracts more air, resulting in a higher air pressure value in the air input pipeline M, the power of the air pump 52 to extract air can be reduced; when the air pump 52 extracts less air, resulting in a lower air pressure value in the air input pipeline M, the power of the air pump 52 to extract air can be increased; for example, when the electrolyzer 30 produces hydrogen at a faster speed, resulting in a higher air pressure value in the air input pipeline M, the power of the electrolyzer 30 can be reduced; when the electrolyzer 30 produces hydrogen at a slower speed, resulting in a lower air pressure value in the air input pipeline M, the power of the electrolyzer 30 can be increased. For example, when the nasal suction tube connected to the hydrogen inhalation port 23 is blocked, bent, etc., resulting in an excessively high air pressure value in the air input pipeline M, the control module controls the electrolyzer 30 to reduce power or stop producing hydrogen, and simultaneously controls the air pump 52 to reduce power or stop extracting air. Figure 1 and Figure 3In the illustrated embodiment, when the air pressure value exceeds the preset pressure range, the control module controls the electrolyzer 30 to stop producing hydrogen and the air pump 52 to stop extracting air. In some specific embodiments, it can also be configured as follows: when the air pressure value in the air input pipeline M reaches the first preset pressure value, the control module controls the electrolyzer 30 to reduce the hydrogen production speed and controls the air pump 52 to reduce the power of extracting air; when the air pressure value in the air input pipeline M further reaches the second preset pressure value, the control module controls the electrolyzer 30 to stop producing hydrogen and controls the air pump 52 to stop extracting air. Through such a configuration, it is possible to prevent the air pressure value from being too large to damage the air pump 52, the air input pipeline M, and the mixed gas output pipeline Q, and it is also possible to eliminate the harm caused by the accumulation of hydrogen. In addition, when the hydrogen generator 100 is used as an embodiment of a hydrogen respirator, the component ratio and air pressure of the mixed gas can be adjusted by adjusting the power of the air pump 52 and the power of the electrolyzer 30. The user can perform customizable size operations on the inhaled mixed gas as needed, so that different groups of people can increase or decrease the flow rate of the mixed gas as needed, and improve the experience of inhaling the mixed gas. For example, if the power of the air pump 52 is reduced, the air in the air input pipeline M is reduced. If the flow rate or pressure of the hydrogen output from the hydrogen output pipeline N remains unchanged, the concentration of hydrogen in the mixed gas increases. Within the scope of ensuring the safety of hydrogen, the rehabilitation or treatment effect can be improved. For example, when the power of the air pump 52 is increased, the air in the air input pipeline M increases. If the flow rate or pressure of the hydrogen output from the hydrogen output pipeline N remains unchanged, the concentration of hydrogen in the mixed gas is reduced, which is suitable for people who are new to hydrogen to adapt to inhaling hydrogen. These operations can be performed by arranging corresponding key operations on the outer shell 70 and executed by the control module.

[0082] In some embodiments, the hydrogen generator 100 may further include a second air pressure sensor, which is disposed on the mixed gas output pipeline Q. The second air pressure sensor is used to detect the mixed gas pressure value of the mixed gas. The second air pressure sensor is connected to a control module, and the control module obtains the mixed gas pressure value and the air pressure value and adjusts the power of the electrolyzer 30 or / and the power of the air pump 52 based on the mixed gas pressure value and the air pressure value. In some embodiments, the control module is connected to the first air pressure sensor 51 and the second air pressure sensor. Based on the air pressure value measured by the first air pressure sensor 51 and the mixed gas pressure value measured by the second air pressure sensor, the control module adjusts the power of the electrolyzer 30 or / and the power of the air pump 52 so that the hydrogen concentration in the mixed gas reaches a preset concentration. In other embodiments, the pressure value of the inhaled gas in the nasal suction tube is directly related to the pressure value of the mixed gas. The control module can adjust the pressure value of the mixed gas by adjusting the power of the electrolyzer 30 and / or the power of the air pump 52, thereby indirectly changing the pressure value of the gas in the nasal suction tube to improve the user experience. In the present application, the first pressure sensor 51 and the second pressure sensor are far away from the hydrogen output pipeline N. The gas pressure value in the hydrogen output pipeline N can be indirectly obtained by obtaining the mixed gas pressure value and the air pressure value, thereby reducing the number of electrical components installed on the hydrogen output pipeline N. Since the hydrogen concentration in the hydrogen output pipeline N is relatively high, such a setting can avoid the potential safety hazards of the hydrogen output pipeline N caused by the burning of electrical components and load short circuit caused by the application of a voltage exceeding the voltage range, thereby improving the safety performance.

[0083] In some embodiments, Figure 4 As shown, the hydrogen generator 100 further includes an air container 53, which is disposed on the air input pipeline M and between the air pump 52 and the air inlet, and is used to store and release the air entering from the air inlet to reduce or prevent the air from causing vibrations to the air input pipeline M. The addition of the air container 53 can reduce or prevent the vibrations caused by the air input pipeline M, which can reduce the operating noise of the hydrogen generator 100 on the one hand, and reduce the pressure fluctuations of the air in the air input pipeline M on the other hand, thereby reducing the pressure fluctuations of the mixed gas and improving the user experience of the hydrogen generator 100.

[0084] In some embodiments, the hydrogen generator 100 further includes a muffler, which is disposed on the air input pipeline M. The muffler is used to reduce or prevent the noise generated by the air inlet entering the air input pipeline M. The addition of the muffler can further reduce the operating noise of the hydrogen generator 100. Figure 4In the illustrated embodiment, the muffler is farther away from the air inlet than the air container 53, that is, the air entering from the air inlet first passes through the air container 53 and then passes through the muffler. After the air passes through the air container 53, the air pressure fluctuation is small and the flow rate is stable. After passing through the muffler, the operating noise of the hydrogen generator 100 can be better reduced overall.
