[0002] At present, products that generate hydrogen are often controlled by switching power supplies powered by AC power and use constant voltage and high current power supplies or constant current power supplies. These are not only bulky, but also have fixed voltage or current drive control, which cannot meet the stability of hydrogen generation by the electrolysis device.

[0003] In addition, the prior art usually introduces the hydrogen generated by the hydrogen generator into a hydrogen processing mechanism for processing. The hydrogen processing mechanism includes a pressure chamber, which is a sealed box with a hydrogen input port and a hydrogen output port on the top and a drain port connected to a water tank on the bottom; the hydrogen output port is controlled to open and close by a first solenoid valve; the drain port is controlled to open and close by a second solenoid valve; in the drainage state, the first solenoid valve is closed and the second solenoid valve is opened, and the hydrogen cannot be discharged after entering the pressure chamber, and will gather in the pressure chamber, and the water in the pressure chamber will be discharged into the water tank through the drain port.

[0043] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] See also Figure 1 , Figure 1 The specific structure of the control circuit of the hydrogen generation device of the present invention is shown, which includes a power supply circuit M3, a sensing circuit M2, a detection circuit M4, an electrolyzer circuit M6, a drive circuit M5 and a main controller M1. Specifically:

[0045] The power supply circuit M3 is used to supply power to the main controller M1, the sensing circuit M2, the detection circuit M4, the electrolytic cell circuit M6 and the driving circuit M5;

[0046] The sensing circuit M2 is used to obtain the control signal input by the user and display the real-time status of the hydrogen generation device;

[0047] The detection circuit M4 is used to detect the state of the water tank in the hydrogen generation device;

[0048] The electrolyzer circuit M6 is used to adjust the output of hydrogen in the hydrogen generation device;

[0049] The driving circuit M5 is used to control the state of the solenoid valve in the hydrogen generation device;

[0050] The main controller M1 is connected to the sensing circuit M2, the detection circuit M4, the electrolytic cell circuit M6 and the driving circuit M5 respectively, and is used to control the sensing circuit M2, the detection circuit M4, the electrolytic cell circuit M6 and the driving circuit M5.

[0051] It should be noted that the control circuit of the present invention is applied to a special hydrogen generating device, which includes two working modes: "hydrogen absorption mode" and "hydrogen flow mode". When the user needs to directly inhale hydrogen, the inhalation pipe can be connected to the hydrogen outlet, and the hydrogen absorption button can be touched to start the hydrogen absorption mode of the hydrogen generating device; when the user needs to add hydrogen to the liquid, the hydrogen flow button can be touched to start the hydrogen flow mode of the hydrogen generating device.

[0052] When working, the detection circuit M4 detects the state of the water in the water tank of the hydrogen generating device in real time (such as water quality, water temperature, water level, etc.), and sends the water body signal to the main controller M1, and then the main controller M1 drives the sensing circuit M2 to display the water body state. At the same time, the sensing circuit M2 can obtain the control signal (such as hydrogen absorption signal and hydrogen flow signal) input by the user by touching the hydrogen absorption button / hydrogen flow button in real time, and send the control signal to the main controller M1; when the user selects the "hydrogen absorption mode", the main controller M1 opens the solenoid valve through the driving circuit M5, and displays the working mode of the hydrogen generating device as the "hydrogen absorption mode" through the sensing circuit M2; when the user selects the "hydrogen flow mode", the main controller M1 closes the solenoid valve through the driving circuit M5, and displays the working mode of the hydrogen generating device as the "hydrogen flow mode" through the sensing circuit M2. Correspondingly, the electrolyzer circuit M6 also adjusts the output of hydrogen in the hydrogen generating device in real time by limiting the pressure and controlling the flow, so as to achieve the effect of efficient and constant output of hydrogen.

[0053] like Figure 2 As shown, the main controller M1 includes a main control chip U4 and peripheral circuits. The main control chip U4 is preferably STM32F030C8T6, but is not limited thereto.

[0054] The main controller M1 reads the signals sent by the sensing circuit M2 and the detection circuit M4 in real time (such as hydrogen absorption signal, hydrogen flow signal, water quality signal, water temperature signal, and water level signal), and displays the real-time status of the hydrogen generation device through the sensing circuit M2, thereby achieving the effect of human-computer interaction.

[0055] like Figure 3 As shown, the power supply circuit M3 includes an adaptation circuit A1, a primary step-down circuit A2, a secondary step-down circuit A3, a tertiary step-down circuit A4 and a quaternary step-down circuit A5. Specifically:

[0056] The input end of the adapter circuit A1 is connected to the power adapter to obtain the initial input voltage. It should be noted that the adapter circuit A1 has a built-in USB-PD protocol chip U3, and the USB-PD protocol chip U3 communicates with the USB-PD power adapter to obtain an initial input voltage of 20V. The USB-PD protocol chip U3 is preferably CH224, but is not limited thereto.

[0057] The input end of the primary step-down circuit A2 is connected to the output end of the adaptation circuit A1, and the primary step-down circuit A2 adjusts the initial input voltage to a primary power supply voltage to power the electrolytic cell circuit M6. The primary step-down circuit A2 can stabilize the initial input voltage of 20V to form a stable primary power supply voltage of 20V.

[0058] The input end of the secondary step-down circuit A3 is connected to the output end of the primary step-down circuit A2, and the secondary step-down circuit A3 adjusts the primary power supply voltage to a secondary power supply voltage to power the drive circuit M5. The secondary step-down circuit A3 can step down the primary power supply voltage of 20V to form a secondary power supply voltage of 12V.

[0059] The input end of the three-stage buck circuit A4 is connected to the output end of the two-stage buck circuit A3, and the three-stage buck circuit A4 adjusts the two-stage power supply voltage to a three-stage power supply voltage to power the drive circuit M5. The three-stage buck circuit A4 can buck the 12V two-stage power supply voltage to form a 5V three-stage power supply voltage.

[0060] The input end of the four-stage buck circuit A5 is connected to the output end of the three-stage buck circuit A4, and the four-stage buck circuit A5 adjusts the three-stage power supply voltage to a four-stage power supply voltage to supply power to the main controller M1, the sensing circuit M2 and the detection circuit M4. The four-stage buck circuit A5 can buck the three-stage power supply voltage of 5V to form a four-stage power supply voltage of 3.3V.

[0061] Therefore, the power circuit M3 communicates with the USB-PD power adapter through the USB-PD protocol chip U3 to obtain an initial input voltage of 20V, and then performs multi-stage voltage reduction processing on the initial input voltage to form 12V, 5V, and 3.3V voltages for use by other circuits.

[0062] like Figure 4 and Figure 5 As shown, the sensing circuit M2 includes a touch circuit and an indication circuit.

[0063] like Figure 4 As shown, the touch circuit includes a touch chip U1, the input end of the touch chip U1 is connected to the touch button of the hydrogen generation device, and the output end of the touch chip U1 is connected to the main controller M1; the touch chip is preferably BS812A, but not limited to this.

[0064] like Figure 5 As shown, the input end of the indicating circuit is connected to the main controller M1, and the indicating circuit includes a plurality of light emitting circuits connected in parallel to each other, and the light emitting circuits are used to display the real-time status of the hydrogen generating device. Each light emitting circuit includes at least one resistor (R1-R9) and a light emitting diode (D1-D9).

[0065] For example, when the dehydrogenation generating device is timed for 1 hour, the LED D1 is lit; when the dehydrogenation generating device is timed for 2 hours, the LED D2 is lit; when the dehydrogenation generating device is timed for 3 hours, the LED D3 is lit; when the water quality in the water tank is abnormal, the LED D4 is lit; when the water level in the water tank is too high, the LED D5 is lit; when the water level in the water tank is too low, the LED D6 is lit; when the dehydrogenation generating device is in maintenance status, the LED D7 is lit; when the water temperature in the water tank is abnormal, the LED D8 is lit; when the power supply circuit M3 is abnormal, the LED D9 is lit.

[0066] Therefore, the user's action command can be sent to the main controller M1 through the sensing circuit M2, and displayed by the indicator circuit through the light-emitting diode, so that the user can timely understand the real-time status of the hydrogen generation device, thereby realizing human-computer interaction;

[0067] like Figure 6-8 As shown, the detection circuit M4 includes a water quality detection circuit, a temperature detection circuit and a water level detection circuit.

[0068] like Figure 6 As shown, the water quality detection circuit includes a water quality detection probe P7, and the water quality detection probe P7 is used to detect the impurity content of the water in the water tank; it should be noted that during the water quality detection process, the resistance value of the water quality detection probe P7 (i.e., the conductivity of the water) can be detected in real time through an alternating electrical signal, thereby achieving the function of detecting water quality.

[0069] like Figure 7 As shown, the temperature detection circuit includes a thermistor P14, and the thermistor P14 is used to detect the temperature of water in the water tank.

[0070] like Figure 8 As shown, the water level detection circuit includes a water level switch P8, and the water level switch P8 is used to detect the water level height in the water tank.

[0071] Therefore, the water quality detection circuit, the temperature detection circuit and the water level detection circuit can respectively perform real-time detection of the water state in the water tank with high accuracy.

[0072] like Fig. 9 As shown, the electrolytic cell circuit M6 includes a voltage limiting and current control chip U4, a voltage regulating circuit B2 and a sampling circuit B1. The voltage limiting and current control chip U4 is preferably MP2918, but is not limited thereto.

[0073] The sampling circuit B1 is used to collect the output current of the voltage regulating circuit B2, and feed the output current back to the voltage limiting and current controlling chip U4;

[0074] The voltage limiting and current controlling chip U4 is used to adjust the output current of the voltage regulating circuit B2 to adjust the output amount of hydrogen in the hydrogen generating device.

[0075] Therefore, the electrolyzer circuit M6 achieves high efficiency and constant hydrogen output by limiting voltage and controlling current.

[0076] like Fig.10 As shown, the driving circuit M5 includes a solenoid valve circuit, an input end of the solenoid valve circuit is connected to the main controller M1, and an output end is connected to the solenoid valve P5 of the hydrogen generation device.

[0077] Furthermore, the driving circuit M5 also includes a lighting circuit, a buzzer circuit, a fan circuit and a reserved circuit connected to the main controller M1;

[0078] like Fig.11 As shown, the lighting circuit includes a lighting lamp P3, and the lighting lamp P3 is arranged in the water tank to realize water tank lighting;

[0079] like Fig.12 As shown, the buzzer circuit includes a buzzer P2. When the hydrogen generation device is abnormal, the buzzer P2 can be used to warn the user, so that the user can handle it in time;

[0080] like Fig.13 As shown, the fan circuit includes a heat dissipation fan P4, and the heat dissipation fan P4 is used to dissipate heat for the control circuit.

[0081] like Fig.14 As shown, the reserved circuit can reserve port P6 for the cooling fan or the solenoid valve for subsequent function expansion.

[0082] It should be noted that the drive circuit M5 can convert the control signal output by the main controller M1 into a control signal with a larger power to drive the solenoid valve P5, the lighting lamp P3, the buzzer P2, and the cooling fan P4 to work.

[0083] In summary, the control circuit of the hydrogen generation device of the present invention adopts a unique circuit structure, which realizes effective control of the hydrogen generation device with strong flexibility and high precision.

[0084] See also Figure 15-21 , Figure 15-21 The specific structure of the hydrogen generation device of the present invention is shown, which includes a hydrogen generator, a gas-water separator and a control circuit; the hydrogen generator is used to generate hydrogen, and the gas-water separator is used to humidify the generated hydrogen and treat the moisture brought out during the hydrogen generation process.

[0085] The specific structures of the hydrogen generator and the gas-water separator are further explained below.

[0086] Hydrogen Generator:

[0087] See also Fig.15 The hydrogen generator comprises an electrolytic cell 2 and a water tank 1 connected to each other. Fig.16 The electrolytic cell 2 includes a first fixed plate 21, a first insulating plate 22, an anode electrolytic plate 23, a first titanium fiber plate 24, an ion membrane 25, a second titanium fiber plate 26, a cathode electrolytic plate 27, a second insulating plate 28 and a second fixed plate 29 which are arranged in sequence. The anode electrolytic plate 23 is provided with a water flow groove 231, which runs through the anode electrolytic plate 23. The water flow groove 231 is curved from bottom to top, and the lower part of the water flow groove 231 is connected to the water inlet 232, and the upper part is connected to the water outlet 233; the cathode electrolytic plate 27 is provided with an air outlet 271, and the air outlet 271 is connected to the first titanium fiber plate 24. The first fixing plate 21 and the second fixing plate 29 can be made of aluminum alloy, the first insulating plate 22 and the second insulating plate 28 can be silicone plates, rubber plates or plastic plates, the anode electrolytic plate 23 needs to be a titanium substrate, the cathode electrolytic plate 27 can be a general conductive metal plate, and the surface of the ion membrane 25 can be coated or electroplated with a precious metal catalyst, such as a platinum catalyst. The water tank 1 is connected to the water inlet 232 and the water outlet 233 through a conduit, and the connection position of the conduit connecting the water inlet 232 and the water tank 1 is lower than the connection position of the conduit connecting the water outlet 233 and the water tank 1.

[0088] During operation, the cathode electrolytic plate 27 is connected to the negative electrode of the DC power supply, and the anode electrolytic plate 23 is connected to the positive electrode of the DC power supply. The cathode electrolytic plate 27 transmits the electric field to the second titanium fiber plate 26, and the anode electrolytic plate 23 transmits the electric field to the first titanium fiber plate 24, so that a potential difference is formed on both sides of the ion membrane 25. The hydrogen ions and cations in the water move in a directional manner under the action of the potential difference, and hydrogen is generated on one side of the ion membrane 25 and oxygen is generated on the other side. The generated hydrogen is transmitted back to the cathode electrolytic plate 27 through the second titanium fiber plate 26, and the generated oxygen is transmitted back to the anode electrolytic plate 23 through the first titanium fiber plate 24.

[0089] The water tank 1 may be provided with a water level switch and a water quality detection probe. The water level switch is connected to the water level detection circuit in the control circuit and is used to detect the water level of the water tank 1. Since the ion membrane is a component of the electrolytic cell, if there are too many mineral ions in the water during the catalytic electrolysis process, the gaps in the ion membrane will be blocked, causing the ion membrane to affect the catalytic efficiency and shorten its life. The water quality detection probe is connected to the water quality detection circuit in the control circuit and is used to monitor the TDS of the water in the water filling tank in real time. If the TDS is too large, it stops working and the indicator light alarms; the water quality detection probe uses a pure titanium screw needle.

[0090] In the present invention, a row of bolts 3 are arranged at the edges of the first fixing plate 21 and the second fixing plate 29 , so that uniform pressure is applied to the various plates between the first fixing plate 21 and the second fixing plate 29 . Under the support of the above pressure, a sealed chamber is formed between the anode electrolytic plate 23 and the ion membrane 25, and between the cathode electrolytic plate 27 and the ion membrane 25 through the rubber sealing frame 20; a first titanium fiber plate 24 and a second titanium fiber plate 26 with a flat surface are arranged in the sealed chamber, and the hydrophobicity and air permeability of the first titanium fiber plate 24 and the second titanium fiber plate 26 are used to ensure that the surface of the ion membrane 25 is continuously covered with water, and the generated gas can be discharged from the first titanium fiber plate 24 and the second titanium fiber plate 26 in time; the conductivity of the first titanium fiber plate 24 and the second titanium fiber plate 26 is used to form a uniform electric field on both sides of the ion membrane 25 to ensure the stable progress of the electrolysis reaction; the physical properties of the first titanium fiber plate 24 and the second titanium fiber plate 26, which are high in strength, dense in pores, and flat and smooth in surface, are used to clamp various parts of the ion membrane 25 to prevent the ion membrane 25 from being repeatedly expanded and contracted by periodic force during the electrolysis process, thereby extending the service life of the ion membrane 25.

[0091] At the anode reaction end, it is necessary to ensure that the water and the ion membrane 25 are in full contact, and the generated oxygen can be discharged in time. The existing anode electrolytic plate needs to be milled to form a water flow channel. Since the material of the anode electrolytic plate is titanium, the tool is easy to wear during the cutting of the titanium substrate, and the tool cost is relatively high, resulting in excessively high milling cost and low production efficiency. In addition, there is also a punched titanium mesh pad between the anode electrolytic plate and the first titanium fiber plate. Since the four sides of the titanium mesh are uneven, water can flow through the gap formed with the contact surface of the anode electrolytic plate, but the waterway is narrow and the water flow is not particularly ideal. See Fig.18 The present invention adopts a through-hole water flow groove 231, that is, the anode electrolytic plate 23 is punched to form a through-hole water flow groove 231, so that the water flow and the air flow are unobstructed.

[0092] Since the water flow trough 231 of the present invention is a through-hole structure, the anode electrolysis plate of the present invention can be directly processed by a sheet metal punching and blanking die, which has high processing efficiency and low cost. Since the anode electrolysis plate 23 does not use a blind hole water flow trough, the thickness of the anode electrolysis plate 23 can be less than or equal to 1 mm, effectively reducing the weight and volume of the overall hydrogen generator. Since the cost of the titanium substrate is very high, the thickness of the anode electrolysis plate 23 of the present invention is reduced from the existing 2 mm to less than 1 mm, effectively reducing the cost. The shape of the water flow trough 231 of the present invention is not limited to a curved shape, and other water flow troughs 231 of different shapes all fall within the protection scope of the present invention.

[0093] Preferably, the anode electrolytic plate 23 of this embodiment is provided with two groups of symmetrically arranged water flow grooves 231, and the two groups of water flow grooves 231 are independent of each other. The water entering from the lower water inlet 232 is divided into two paths and flows in the water flow grooves 231. The two paths of water flow can quickly replenish water for the first titanium fiber plate 24; in addition, the generated oxygen bubbles are respectively discharged from the water flow in the two groups of water flow grooves 231 to the water outlet 233, which can ensure the continuous discharge of oxygen and thus ensure the smoothness of the hydrogen production process. Since the water flow groove 231 of the invention runs through the anode electrolytic plate 23, the generated oxygen bubbles will not gather too quickly in the water flow groove 231, become large bubbles, and hinder the flow of water. The small bubbles in the water flow groove 231 move upward, and at the same time bring the power of upward flow to the water flow, so that only the water inlet 232 and the water outlet 233 need to be directly connected to the water tank 1, and there is no need to set an active power device such as a water pump, and the water flow can spontaneously enter from the water inlet 232 and flow out from the water outlet 233.

[0094] Preferably, the width of the position where the water flow groove 231 is connected to the water inlet 232 and the water outlet 233 is greater than the width of the remaining parts to prevent the water flow in the entire water flow groove from being unable to flow or the gas pressure from increasing abnormally due to blockage of the water inlet or outlet channel.

[0095] As mentioned above, in order to make the electrolysis reaction of water in the first titanium fiber plate 24, the ion membrane 25 and the second titanium fiber plate 26 rapid and stable, it is necessary to ensure that the first titanium fiber plate 24 and the second titanium fiber plate 26 are evenly pressed against the surface of the ion membrane 25, and at the same time provide them with a watertight and airtight environment. To this end, the first titanium fiber plate 24, the ion membrane 25 and the second titanium fiber plate 26 are provided with a silicone sealing frame 20 on the periphery. When the first fixed plate 21 and the second fixed plate 29 apply pressure to the anode electrolytic plate 23 and the cathode electrolytic plate 27, the anode electrolytic plate 23 and the cathode electrolytic plate 27 press the silicone sealing frame 20 to form a sealed space between the anode electrolytic plate 23 and the cathode electrolytic plate 27; the anode electrolytic plate 23 abuts against the first titanium fiber plate 24, the cathode electrolytic plate 27 abuts against the second titanium fiber plate 26, and the first titanium fiber plate 24 and the second titanium fiber plate 26 evenly clamp the ion membrane 25. The ion membrane 25 extends from the four edges of the first titanium fiber plate 24 and the second titanium fiber plate 26 and is clamped by the silicone sealing frame 20; a sealed water flow chamber is formed between the anode electrolytic plate 23, the silicone sealing frame 20 and the ion membrane 25, and a sealed hydrogen chamber is formed between the cathode electrolytic plate 27, the rubber sealing frame 20 and the ion membrane 25. Through the above structure, the close contact between the first titanium fiber plate 24, the ion membrane 25 and the second titanium fiber plate 26 is not affected by the assembly accuracy, and the peripheral sealing is completed by the elastic silicone sealing frame 20, which reduces the tolerance accuracy requirements of each component and is more conducive to assembly.

[0096] The oxygen generated by the electrolyzer re-enters the water tank 1 through the water outlet 233, so the water tank 1 must have an exhaust function. In addition, in order to improve the portability of the device, the water tank 1 should be able to prevent water from pouring out while being able to exhaust. To this end, the top of the water tank 1 is provided with a cover 11, see Fig.19 , the cover 11 is provided with a water-stopping vent cavity 111; the water-stopping vent cavity 111 is provided with a lower vent hole 112, an upper vent hole 113 and a receiving cavity 114, and a round ball 115 is provided in the receiving cavity 114. Specifically, the diameter of the round ball 115 is larger than the diameter of the lower vent hole 112 and the upper vent hole 113 respectively; in the initial state, the round ball 115 blocks the lower vent hole 112, and the upper vent hole 113 is connected to the receiving cavity 114. When the air pressure in the water tank 1 is greater than the ambient air pressure, the gas in the water tank 1 pushes the round ball 115 to move upward, and the gas in the water tank 1 enters the receiving cavity 114 through the lower vent hole 112, and then is discharged through the upper vent hole 113. When the device is tilted, the water in the water tank 1 flows into the receiving cavity 114 through the lower vent hole 112, pushing the round ball 115 to block the upper vent hole 113 to prevent the water in the water tank 1 from flowing out. The cover structure of this solution is simple, and components such as springs are omitted, which effectively increases the service life of the device. Preferably, the ball 115 is a steel ball.

[0097] It should be noted that when the air pressure in the water tank 1 is greater than the ambient air pressure, the thrust generated by the gas in the water tank 1 on the ball 115 is not enough to push the ball to block the upper vent 113. The technicians can design it according to the size, weight and size of the ball, and the present invention does not make any specific limitation.

[0098] Preferably, a handle portion 116 is provided on the top of the cover 11, which is higher than the plane where the cover is located, and the top surface of the handle portion 116 is ridge-shaped; the upper vent 113 is provided on the top surface of the handle portion 116. In daily use, dust is not easily accumulated on the top surface of the handle portion 116 that is higher than the plane where the cover is located, and the ridge-shaped top surface is not easily completely covered by debris. Therefore, the upper vent 113 provided thereon is not easily blocked, ensuring reliable use.

[0099] Gas-water separator:

[0100] See also Fig. 20 The hydrogen generated by the hydrogen generator is introduced into the gas-water separator for gas-water separation. The gas-water separator includes a pressure chamber 4, which is a sealed box body, with a hydrogen output port 41 on the top, a hydrogen input port 42 and a water outlet 43 on the bottom; the hydrogen output port 42 is connected to the hydrogen outlet 5, and the water outlet 43 is connected to the water tank 1.

[0101] See also Fig.21, at least one baffle 44 is provided in the pressure chamber 4, and the baffle 44 is arranged between the hydrogen inlet 42 and the hydrogen outlet 41. The hydrogen entering the pressure chamber 4 from the hydrogen inlet 42 collides with the baffle 44, and the water in the hydrogen flows to the bottom of the pressure chamber 4 along the baffle 44. Specifically, the baffle 44 is connected to one side wall of the pressure chamber 4 and is not connected to the other side wall. In order to increase the moving distance of the hydrogen in the pressure chamber 4, two adjacent baffles 44 are symmetrically arranged, that is, two adjacent baffles 44 are respectively connected to the side walls on both sides of the pressure chamber 4. In order to further improve the drying effect and prevent the water separated in the pressure chamber 4 from re-wetting the hydrogen, a hydrogen inlet pipe 45 connected to the hydrogen inlet 42 is provided in the pressure chamber 4, and the gas outlet of the hydrogen inlet pipe 45 is located at the upper part of the pressure chamber 4. Preferably, a notch 441 is provided on the top of the baffle 44 , and the outlet of the hydrogen inlet pipe 45 is flush with the notch 441 , so that the hydrogen coming out of the outlet collides with the baffle 44 , wherein the notch 441 can increase the collision chance of the hydrogen and the baffle 44 .

[0102] The hydrogen outlet 5 is a microporous structure. When the rate at which hydrogen overflows from the hydrogen outlet 5 is lower than the rate at which the hydrogen generator supplies hydrogen to the pressure chamber 4, the pressure in the pressure chamber 4 increases, and the water in the pressure chamber 4 is automatically discharged into the water tank 1. The rate at which the hydrogen generator supplies hydrogen to the pressure chamber 4 is substantially constant, and the rate at which hydrogen overflows from the hydrogen outlet 5 is related to the size of the hydrogen outlet 5 and the pressure chamber 4. When the rate at which the hydrogen generator supplies hydrogen to the pressure chamber is constant and the size of the pressure chamber remains unchanged, the larger the diameter of the hydrogen outlet 5, the faster the rate at which hydrogen overflows from the hydrogen outlet 5. When the discharge rate of hydrogen is greater than the entry rate of hydrogen, the pressure in the pressure chamber 4 will not increase. Only when the diameter of the hydrogen outlet 5 is small enough can the discharge rate of hydrogen be ensured to be less than the entry rate of hydrogen. In addition, the diameter of the hydrogen input port 42 is greater than the diameter of the hydrogen output port 41. Preferably, the diameter of the hydrogen outlet 5 is 0.4-0.5 μm. If the diameter of the hydrogen outlet 5 is too small, less than 0.4 μm, since part of the hydrogen still contains a small amount of water, the hydrogen outlet 5 is easily blocked by hydrogen, and the hydrogen cannot be discharged from the hydrogen outlet 5. In a normal state, hydrogen continues to enter the pressure chamber 4, hydrogen continues to be discharged from the hydrogen outlet 5, and the pressure in the pressure chamber 4 continues to increase. When the pressure in the pressure chamber 4 increases to a preset value, the water in the pressure chamber 4 is automatically discharged into the water tank 1, thereby preventing the water in the pressure chamber 4 from overflowing.

[0103] It should be noted that the hydrogen discharged from the hydrogen outlet 5 is dry hydrogen and can be used directly. When the hydrogen outlet 5 is connected to the inhalation pipe, the hydrogen can be supplied to the user for inhalation. Fig. 22When the hydrogen port 5 is connected to the hydrogen container 6, hydrogen can be added to the liquid for drinking by the user, and the liquid can be water, juice, tea, milk, milk tea and other beverages. The output pressure of hydrogen varies with different application modes.

[0104] Specifically, when the hydrogen is supplied to the user for direct inhalation, the output pressure of the hydrogen is in a normal state; when the hydrogen needs to be introduced into the liquid by the hydrogen container 6, the hydrogen is in a pressurized state. In order to switch between the two states, the drain port 43 is controlled to open and close by a solenoid valve 46.

[0105] In the normal state, the solenoid valve 46 is open, the discharge rate of hydrogen in the pressure chamber 4 is lower than the entry rate of hydrogen, the pressure in the pressure chamber 4 increases, and the water in the pressure chamber 4 is discharged into the water tank 1 through the drain port 43. After the water in the pressure chamber 4 is drained, the pressure in the pressure chamber 4 is normal, and the hydrogen outlet 5 discharges non-pressurized hydrogen;

[0106] In the pressurized state, the solenoid valve 46 is closed, the discharge rate of hydrogen in the pressure chamber 4 is lower than the entry rate of hydrogen, the pressure in the pressure chamber 4 increases, the water in the pressure chamber 4 cannot be discharged, the pressure in the pressure chamber 4 continues to increase, and the hydrogen outlet 5 discharges pressurized hydrogen.

[0107] It should be noted that in order to ensure that hydrogen can be quickly added to the liquid, the pressure in the pressure chamber is 0.3-0.8 kpm in the pressurized state. In the normal state, the pressure in the pressure chamber is the standard atmospheric pressure.

[0108] The time for adding hydrogen into the liquid will not last very long, that is, the equipment is in a pressurized state for a very short time, generally a few seconds, and the water in the pressure chamber will not overflow within a few seconds.

[0109] When the device is shut down from a pressurized state or a normal state, the solenoid valve 46 will automatically open, so that the pressure chamber 4 and the water tank 1 are connected. Since the hydrogen generated by the hydrogen generator has a certain temperature, the hydrogen discharged from the hydrogen outlet 5 has the same temperature. When the device is shut down, since the hydrogen outlet 5 is very small, the hydrogen at the hydrogen outlet 5 cools and condenses into water droplets to block the hydrogen outlet 5. At the same time, the hydrogen in the pressure chamber 4 also cools, causing the pressure in the pressure chamber 4 to be lower than the pressure in the water tank 1. The water in the water tank 1 flows back into the pressure chamber 4. When the device is restarted, the water in the pressure chamber 4 will be discharged from the hydrogen outlet 5 along with the hydrogen.

[0110] In order to solve the above problem, an air input port 47 is further provided on the top of the pressure chamber 4, and the air input port 47 is connected to a one-way valve 48. In the shutdown state, the one-way valve 48 and the solenoid valve 46 are opened, and the external air enters the pressure chamber 4 from the air input port 47 through the one-way valve 48, so that the pressure of the pressure chamber 4 and the water tank 1 is balanced, ensuring that the water level in the pressure chamber 4 is in a normal state, and when the machine is turned on again, the water in the pressure chamber 4 will not be discharged along with the hydrogen.

[0111] In order to ensure that hydrogen can be added to the liquid and prevent the hydrogen in the liquid from quickly overflowing, the hydrogen container 6 is provided with a plurality of nano-scale micropores 61. Under a certain pressure, hydrogen is discharged from the micropores 61 to form a large number of tiny bubbles that are integrated into the liquid.

[0112] In summary, the present invention combines a hydrogen generator, a gas-water separator and a control circuit to simultaneously satisfy the functions of "hydrogen absorption" and "hydrogen flow". The following is an explanation of the method of using the hydrogen generator:

[0113] 1) Add water into the water tank, connect the power circuit, and connect the cathode electrolytic plate to the negative electrode of the DC power supply and the anode electrolytic plate to the positive electrode of the DC power supply through the electrolytic cell circuit to obtain hydrogen and oxygen;

[0114] 2) The obtained oxygen enters the first titanium fiber plate, gathers in the first titanium fiber plate and rises to enter the water outlet of the anode electrolytic plate, re-enters the water tank through the connecting pipe between the water outlet and the water tank, drives the water in the water tank to enter the electrolytic cell from the water inlet and circulate out from the water outlet;

[0115] 3) The obtained hydrogen enters the gas-water separator;

[0116] 4) When the user needs to inhale hydrogen, the inhalation pipe is connected to the hydrogen outlet and the hydrogen inhalation button is touched. The induction circuit sends the hydrogen inhalation signal to the main controller, and then the main controller opens the solenoid valve through the driving circuit. The discharge rate of hydrogen in the pressure chamber is lower than the entry rate of hydrogen, and the pressure in the pressure chamber increases. The water in the pressure chamber is discharged into the water tank through the drain port. After the water in the pressure chamber is drained away, the pressure in the pressure chamber is normal, and the hydrogen outlet discharges non-pressurized hydrogen.

[0117] When the user needs to add hydrogen to the liquid, the user connects the hydrogen container to the hydrogen outlet and touches the hydrogen supply button. The sensing circuit sends the hydrogen supply signal to the main controller, and the main controller then closes the solenoid valve through the drive circuit. The discharge rate of hydrogen in the pressure chamber is lower than the entry rate of hydrogen, the pressure in the pressure chamber increases, the water in the pressure chamber cannot be discharged, the pressure in the pressure chamber continues to increase, and the pressurized hydrogen is discharged from the hydrogen outlet.

[0118] In order to ensure that hydrogen can be quickly added to the liquid, the pressure in the pressure chamber is 0.3-0.8 kpm in the pressurized state. In the normal state, the pressure in the pressure chamber is the standard atmospheric pressure.

[0119] The present invention utilizes a pressure chamber to collect water vapor brought out during the hydrogen production process, and uses the prepared hydrogen to press water back into the water tank within a certain period, without the need for additional driving elements, making the device more compact, light in weight, and easy to carry; the use cycle is long after adding water once, and no maintenance is required during the period, making it easy to use.

[0120] The gas-water separator of the present invention realizes switching between pressurized and non-pressurized states through the cooperation of the pressure chamber, the one-way valve and the solenoid valve, so that the hydrogen produced by the device of the present invention can be directly inhaled by the user or added to liquid for the user to drink.

[0121] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
