[0025] There are two groups of collecting pipes 3, which are fixedly connected to the top of the hydrogen collecting tank 2 and the oxygen collecting tank 13 respectively. The collecting pipes 3 are embedded in the heat dissipation frame 5, and the front and rear ends of the heat dissipation frame 5 are both equipped with protective nets.

[0026] Specifically, Figure 1 and Figure 2 As shown, after hydrolysis, hydrogen is discharged from the hydrogen outlet 6 and oxygen is discharged from the oxygen outlet 11. The discharged hydrogen and oxygen both pass through the collecting tube 3. During the process of hydrogen and oxygen passing through the collecting tube 3, the heat dissipation frame 5 outside the collecting tube 3 can dissipate heat for the collected gas. During heat dissipation, the heat dissipation fan 15 inside the heat dissipation frame 5 is started, and the cooling component inside the heat dissipation frame 5 is in contact with the tube wall of the collecting tube 3.

[0027] Embodiment 2: The bottom end of the sealing cover 8 is fixedly connected with a sealing ring 10, and the sealing ring 10 is embedded in the inside of the electrolytic cell device 1. The two sides of the sealing cover 8 are fixedly connected with mounting blocks 17, and the two sides of the electrolytic cell device 1 are fixedly connected with mounting slots 18. One end of the mounting slot 18 is provided with a positioning hole 20, and the inside of the positioning hole 20 is provided with a positioning rod 19. The mounting block 17 is embedded in the inside of the mounting slot 18, and the positioning rod 19 runs through the inside of the mounting block 17;

[0028] Specifically, Figure 1 and Figure 3 As shown, when the inside of the electrolytic cell device 1 needs to be cleaned, the sealing cover 8 needs to be removed from the electrolytic cell device 1 first. During disassembly, the positioning rod 19 is first moved out from the inside of the mounting slot 18, and then the sealing cover 8 is lifted upwards. The mounting blocks 17 on both sides of the sealing cover 8 can be moved out from the inside of the mounting slot 18.

[0029] Embodiment 3: The top of the proton separation membrane 4 is embedded in the inside of the mounting seat 9, and fixing bolts 21 are installed on both sides of the mounting seat 9.

The first water level sensor 12 inside the electrolyzer device 1 can detect the water level. When the water level passes through the first water level sensor 12, the transportation can be stopped. Then the electrolyzer device 1 electrolyzes the water, and hydrogen is discharged from the hydrogen outlet 6, and oxygen is discharged from the oxygen outlet 11. The discharged hydrogen and oxygen pass through the collecting tube 3. During the process of hydrogen and oxygen passing through the collecting tube 3, the heat dissipation frame 5 outside the collecting tube 3 can dissipate the heat of the collected gas. When dissipating heat, the heat dissipation fan 15 inside the heat dissipation frame 5 is started, and the cooling component inside the heat dissipation frame 5 fits with the tube wall of the collecting tube 3 to improve the heat dissipation effect, and the proton separation The membrane 4 can accelerate the separation efficiency of hydrogen atoms and oxygen atoms in electrolyzed water. During the process of electrolyzing oxygen and hydrogen, the first water level sensor 12 and the second water level sensor 14 can monitor the water level inside the electrolyzer device 1. Once the water level is lower than the second water level sensor 14, the extraction pump 7 can pump water into the raw water tank to the inside of the electrolyzer device 1. When the inside of the electrolyzer device 1 needs to be cleaned, the sealing cover 8 needs to be removed from the electrolyzer device 1 first. When disassembling, first move the positioning rod 19 out of the mounting slot 18, and then lift the sealing cover 8 upwards. The mounting blocks 17 on both sides of the sealing cover 8 can be moved out of the mounting slot 18. This structure realizes the function of easy disassembly and cleaning.
