[0027] The first sealing component 47 includes a first cylinder 471 fixedly connected to the upper edge of the housing 1. A connecting strip 472 is installed on the extended top end of the first cylinder 471. A sealing cylinder 473 is installed on the lower side of the connecting strip 472. The top of the rotating seat 43 is provided with first sealing grooves that match the bottom of the sealing cylinder 473, near the outer side of the array of water suction cylinders 45 and activated carbon mesh cylinders 46.

[0028] The main difference between the second implementation method and the first implementation method is that:

[0029] The second sealing component 5 includes a slide rod 52 that is vertically slidably connected to the middle of the bottom of the housing 1. A traction frame 53 that is slidably connected to the inside of the housing 1 is installed on the top of the slide rod 52. Two sets of sealing rings 54 that are slidably connected to the housing 1 are provided on the upper ends of both sides of the traction frame 53. A set of second sealing grooves is provided on the lower side of the rotating seat 43 near the upper side of the two sets of sealing rings 54. A mounting frame is provided at the bottom of the housing 1. A second cylinder 51 that is connected to the mounting frame is connected to the bottom of the slide rod 52. The two sets of sealing rings 54 are located on the upper side of the intake pipe 2 and the exhaust pipe 3, respectively.

[0030] The extended end of the second cylinder 51 is fixedly connected to the traction frame 53.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0032] In use, the user fixes and connects the front air inlet pipe 2 of the housing 1 to the exhaust end of the hydrogen generator, and connects the rear exhaust pipe 3 of the housing 1 to the external hydrogen recovery end. After the hydrogen generator produces hydrogen, the hydrogen is discharged to the recovery end through the air inlet pipe 2, air inlet groove, water suction cylinder 45, air pipe 44, activated carbon mesh cylinder 46, exhaust groove, and exhaust pipe 3. During this process, the water suction cylinder 45 absorbs moisture from the hydrogen, and the activated carbon mesh cylinder 46 adsorbs odors from the gas, thus achieving purification. When it is necessary to replace the activated carbon mesh cylinder 46 and the water suction cylinder 45, the hydrogen generator and its exhaust valve on the exhaust side are temporarily closed, and the air inlet valve of the hydrogen recovery end is closed. The two sets of first cylinders 471 are used to adjust the two... The height of the connecting strip 472 and the sealing tube 473 is adjusted to separate the sealing tube 473 from the rotating seat 43. The height of the slide rod 52, the traction frame 53, and the two sets of sealing rings 54 are adjusted by the second cylinder 51 to separate the two sets of sealing rings 54 from the lower side of the rotating seat 43. The angle of the rotating seat 43 is adjusted by the motor 42, so that the water suction tube 45 and the activated carbon mesh tube 46 that have not been dried and purified are moved to the upper end of the air inlet and exhaust grooves, respectively. The two sets of sealing tubes 473 and the two sets of sealing rings 54 seal the upper and lower sides of the replaced water suction tube 45 and activated carbon mesh tube 46. Hydrogen is reintroduced into the device for drying and purification, and the previously used water suction tube 45 and activated carbon mesh tube 46 are replaced.
