[0027] The sliding assembly includes a sliding block 8, the outer wall of the air permeable plate 7 is slidably connected to the sliding block 8, the bottom end of the sliding block 8 is fixedly connected to a second spring 9, one end of the sealing shell 5 is fixedly connected to a connecting pipe 10, and the outer wall of the connecting pipe 10 is spirally connected to a gas storage tank 11.

[0028] Among them, Figure 3 As shown, the sealing shell 5 is provided with a sliding groove that matches the push plate 4. The push plate 4 forms a sliding structure with the sealing shell 5 through the first spring 3, which is conducive to releasing hydrogen through the gas outlet 2. The push plate 4 is pushed to slide in the groove of the sealing shell 5 by pressure.

[0029] Among them, Figure 3 As shown, the air permeable plate 7 is provided with a sliding groove that matches the sliding block 8. The sliding block 8 forms a sliding structure with the air permeable plate 7 through the second spring 9, which is conducive to the sliding block 8 being pressed by the push plate 4, so that hydrogen can be transported to the connecting pipe 10 through the holes of the air permeable plate 7 and the sliding block 8, and the pressure in the sealing shell 5 can be adjusted.

[0030] Among them, Figure 2 As shown, two groups of sliding blocks 8 are provided, and the positional relationship of the two groups of sliding blocks 8 is symmetrically distributed about the center of the hydrogen storage tank 1, which is conducive to adjusting the hydrogen delivery state through the contraction of the sliding blocks 8.
