[0051] Specifically, in this embodiment, the first pipeline 501 is connected to the water tank 51 and the water pump 52, the second pipeline 502 is connected to the water tank 51 and the circulating water pump 53, the third pipeline 503 is connected to the circulating water pump 53 and the hydrogen production unit (specifically, the electrolyzer group 61), and the three-way valve 55 is connected to the third pipeline 503, the resin purification tank 54, and the drain pipeline 506.

[0052] In this invention, a conductivity sensor 56 and a resin purification tank 54 are equipped in the water circulation unit to monitor water quality parameters in real time and treat the electrolyzed water to ensure the stable operation of the hydrogen production system.

[0053] like Figures 2 to 6 As shown, in this embodiment, the hydrogen production unit includes an electrolyzer group 61, a condenser 63, a gas-water separator 64, and a water collection tank 66.

[0054] Electrolyzer assembly 61 consists of two electrolyzers used to decompose water into oxygen and hydrogen. Electrolyzer assembly 61 is equipped with a first water outlet 601 and a second water outlet 602. The first water outlet 601 delivers the generated hydrogen and hydrogen-mixed vapor to the condenser 63 via a fifth pipe 603. A first pressure sensor 65 and a pressure relief valve 62 are also installed on the fifth pipe 603 leading to the condenser 63. The second water outlet 602 delivers the generated oxygen and oxygen-mixed vapor to the oxygen circuit unit via a ninth pipe 607.

[0055] Condenser 63 is used to condense the generated hydrogen gas and the vapor mixed with hydrogen gas. In condenser 63, water vapor is condensed into condensate. Condenser 63 delivers the generated hydrogen gas and the condensate mixed with hydrogen gas to steam-water separator 64 through sixth pipeline 604.

[0056] The vapor separator 64 is used to separate hydrogen and the condensate mixed with hydrogen and to transport the hydrogen to the purification unit through the seventh pipeline 605; at the same time, the vapor separator 64 transports the condensate to the water collection tank 66 through the eighth pipeline 606, and the water collection tank 66 then returns the condensate to the water tank 51.

[0057] Specifically, in this embodiment, the fifth pipe 603 is connected to the first water outlet 601 of the electrolytic cell group 61 and the condenser 63, the sixth pipe 604 is connected to the condenser 63 and the steam-water separator 64, the seventh pipe 605 is connected to the steam-water separator 64 and the purification unit (specifically, the purification pipe group 71), the eighth pipe 606 is connected to the steam-water separator 64 and the water collection tank 66, and the ninth pipe 607 is connected to the second water outlet 602 of the electrolytic cell group 61 and the oxygen circuit unit (specifically, the heat exchanger 81).

The hydrogen production unit and purification unit of this utility model integrate detection and protection components such as pressure sensors and pressure relief valves. The pressure sensor is used to determine the pressure of the pipeline and whether the hydrogen cylinder is full. When charging hydrogen, when the second pressure sensor reaches a certain value, hydrogen production stops for a period of time. If the pressure drops, it is determined that the hydrogen cylinder is not full, and hydrogen production is automatically restarted. This process is repeated until the pressure no longer drops, at which point it is determined that the hydrogen cylinder is full, and hydrogen production stops, realizing intelligent automatic hydrogen production. In addition, when hydrogen needs to be filled, simply connect the hydrogen cylinder to the hydrogen outlet port with a quick-connect fitting and press the start button, which greatly simplifies the hydrogen filling process.

The water tank 51 is also equipped with an oxygen venting pipe 507, which is connected to the oxygen venting port 104. Oxygen in the water tank 51 is discharged through the oxygen venting pipe 507.

[0061] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
