[0024] During the specific implementation process, it is worth noting that, with the cooperation of the air inlet plate 21, the suction fan 22 and the dehumidification box 23, after hydrogen is electrolyzed, the hydrogen will enter the dehumidification box 23 through the air inlet plate 21 under the action of the suction fan 22, and will be filtered by the dehumidification plate 24 to remove moisture from the hydrogen. The hydrogen will then enter the storage tank 14 through the connecting pipe 26, making the extracted hydrogen concentration more pure.

The cam 253 is engaged with the outer wall of the dehumidifying box 23 and is fixed to the inner wall of the dehumidifying box 23. The cam 253 is engaged with the outer wall of the dehumidifying box 23 and is fixed to the inner wall of the dehumidifying box 23. The cam 253 is engaged with the outer wall of the dehumidifying box 23 and is fixed to the inner wall of the dehumidifying box 23. The cam 253 is engaged with the inner wall of the dehumidifying box 23 and is fixed to the inner wall of the dehumidifying box 23.

The cam 253 is engaged with the outer wall of the dehumidifying box 23 and is fixed to the inner wall of the spring 254.

[0026] During the specific implementation process, it is worth noting that, under the cooperation of the pull rod 255, the spring 254 and the block 253, when installing the sealing plate 251, it is inserted into the top of the dehumidification box 23, and the block 253 is clamped on the outer wall of the sealing plate 251 under the action of the spring 254, fixing the sealing plate 251 on the top of the dehumidification box 23. When removing the sealing plate 251, the pull rod 255 is pulled to separate the block 253 from the sealing plate 251, and the sealing plate 251 is removed.

[0027] Furthermore, an alarm device 3 is installed inside the dehumidification box 23, and the alarm device 3 includes: a humidity sensor 31, fixedly connected to the bottom of the sealing plate 251; an alarm 32, electrically connected to the humidity sensor 31, and fixedly connected to the top of the sealing plate 251; wherein, through the cooperation of the humidity sensor 31 and the alarm 32, the dehumidification plate 24 is replaced when the humidity in the dehumidification box 23 becomes large, wherein the models of the alarm 32 and the humidity sensor 31 are not limited, and they can meet the actual usage conditions. A controller should be installed between the alarm 32 and the humidity sensor 31 to ensure that the humidity sensor 31 transmits the signal to the controller, and the controller issues an instruction to make the alarm 32 sound an alarm. wherein the alarm 32 can use an audible and visual alarm, and the specific model is not limited, and it can meet the technical solution recorded in this embodiment;

[0028] In the specific implementation process, it is worth noting that the dehumidification plate 24 is replaced when the humidity in the dehumidification box 23 becomes high due to the cooperation of the humidity sensor 31 and the alarm 32;

[0029] Specifically, when using the low-pressure electrolysis hydrogen production device, when hydrogen is produced in the box body 1, the generated hydrogen enters the dehumidification box 23 through the air inlet plate 21 under the action of the suction fan 22, and is filtered by the dehumidification plate 24 to remove moisture from the hydrogen, and enters the storage tank 14 through the connecting pipe 26, so that the extracted hydrogen concentration is purer. When the humidity of the dehumidification plate 24 in the dehumidification box 23 is high, the humidity sensor 31 will be triggered, and the alarm 32 will prompt to replace the dehumidification plate 24 in the dehumidification box 23. When replacing, pull the pull rod 255 to separate the block 253 and the sealing plate 251, disassemble the sealing plate 251, and replace the dehumidification plate 24.

[0030] Example 2: By Figure 1-4It can be seen that a water supply device 4 is installed inside the box body 1. The water supply device 4 includes: a water outlet pipe 41, which is fixedly connected to the inner wall of the fixing frame 18 and extends to the bottom of the fixing frame 18; a water pump 42, the output end of which is connected to the end of the water outlet pipe 41 extending to the outside of the box body 1 and is fixedly connected to the top of the box body 1; a water tank 43, which is fixedly connected to the top of the box body 1 and connected to the input end of the water pump 42; wherein, through the cooperation of the water outlet pipe 41 and the water pump 42, the water tank 43 supplies water to the box body 1, wherein the model of the water pump 42 is not limited, and can meet the actual usage conditions;

[0031] During the specific implementation process, it is worth noting that, with the cooperation of the water tank 43, the water pump 42 and the water outlet pipe 41, when the electrode hydrogen production is carried out, the water level in the box 1 will drop. At this time, the water pump 42 is used to pump the water in the water tank 43 into the box 1 through the water outlet pipe 41, so that the water level in the box 1 rises to meet the subsequent electrolytic hydrogen production.

[0032] Furthermore, the outer wall of the box body 1 is connected to a pressure relief pipe 15, and a pressure relief valve 16 is installed at one end of the pressure relief pipe 15 away from the box body 1;

[0033] In the specific implementation process, it is worth noting that, with the cooperation of the pressure relief pipe 15 and the box body 1, when the pressure in the box body 1 is too high, the pressure relief valve 16 will be pushed open, so that the air pressure in the box body 1 becomes smaller;

[0034] Specifically, based on the above embodiment, after hydrogen is produced in the box body 1, hydrogen will enter the storage tank 14 through the connecting pipe 26, and the electrolyte water level in the box body 1 will decrease. At this time, the water in the water tank 43 is pumped into the box body 1 through the outlet pipe 41 by the water pump 42. When water is added, the pressure in the box body 1 will increase, and the pressure relief valve 16 at the end of the pressure relief pipe 15 will be opened to reduce the pressure in the box body 1.
