In order to facilitate the entry of water and the extraction of hydrogen, a water inlet connector 204 and a hydrogen outlet connector 205 are installed on the top surface of the chamber body 201.

[0029] The main housing 1 also houses a water tank 4 and a water pump 11. The water tank 4 contains clean water. The water inlet of the water pump 11 is connected to the first water tank connector 23 of the water tank 4 via a pipe, and the water outlet is connected to the water inlet connector 204 via an inlet pipe.

The main shell 1 is equipped with a lighting start switch 15. The lighting start switch 15 and the positioning module 22 are electrically connected to the single-chip computer 9. The positioning module 22 adopts a GPS module.

[0036] In order to close the main shell 1 and to facilitate assembly and maintenance, a right cover plate 101 is installed on the side of the main shell 1 where the reaction chamber 2 is located, a left cover plate 102 is installed on the other side near the power management module 7, and a sub-cover plate 103 is installed on the part where the drying tube 5 is located.
