[0028] Working principle: At the start of operation, the operator uses a small liquid pump 11 on the water storage tank 10 to pump water stored in the tank through pipes to the electrolysis tank 2 and the water cooling pipes 9 in the water cooling chamber 8. Simultaneously, alkaline liquid from the alkaline liquid tank 7 is pumped into the electrolysis tank 2 in a specific ratio through pipes. Then, the power supply 3 before the electrolysis tank 2 is activated, powering the electrolysis tank 2... The cathode 4 and anode 5 inside the electrolysis tank 2 are energized. After that, the electrolyte formed by the mixture of water and alkaline liquid undergoes an electrolytic reaction in the electrolysis tank 2. Hydrogen is generated at the cathode and oxygen is generated at the anode. The generated hydrogen is pumped into the water-cooled chamber 8 by the air pump 12. In the water-cooled chamber 8, it is cooled by the water-cooled pipe 9. Then, it is pumped by the air pump 12 through the pipe to the gas-water separator 13, which separates the hydrogen from the residual water vapor droplets in the pipe. After passing through the gas-water separator 13, the worker can know the hydrogen content in the pipe through the air pressure sensor 13. The worker can open the valve 15 to deliver the hydrogen to the hydrogen tank 16. At the same time, the oxygen is also driven to the oxygen tank 18 by the small air pump 17 through the pipe. When the acidity and alkalinity of the electrolyte in the electrolysis tank 2 is low, the worker can observe the internal acidity and alkalinity through the pH meter 19. The alkaline liquid in the alkaline liquid tank 7 can be delivered to the electrolysis tank 2 in a certain amount. This cycle is repeated to produce hydrogen by electrolysis of water.
