[0027] Please refer to Figures 1 to 3 , an embodiment of the present application provides a box device for hydrogen production by electrolyzing water. The box device includes a first box body 10 and a second box body 20. A first chamber for placing an electrolytic cell is defined inside the first box body 10. A first air outlet communicating with the first chamber is provided at the top of the first box body 10. A first exhaust assembly 30 is provided at the first air outlet, and a first air inlet 10a communicating with the first chamber is provided at the lower part of the first box body 10; the second box body 20 is detachably connected to the first box body 10.

Among them, under the action of the first exhaust assembly 30, the air intake volume of the first air inlet 10a is less than the air outlet volume of the first air outlet, so that a slightly negative pressure state is maintained in the first chamber; under the action of the second exhaust assembly 40, the air intake volume of the second air inlet 20a is less than the air outlet volume of the second air outlet, so that a slightly negative pressure state is maintained in the second chamber.

[0028] Exemplarily, the detachable connection structure between the first box body 10 and the second box body 20 can adopt a snap-fit method, that is: a card slot is provided on one side of the first box body 10, and a protruding card block is provided on the side of the second box body 20 relative to the first box body 10. The detachable connection between the first box body 10 and the second box body 20 is realized by the mutual cooperation of the card block and the card slot. The structure is simple and can be quickly assembled according to different needs. The above is only an example, but not limited thereto. Other detachable connection methods in the prior art can also be adopted.

[0029] Exemplarily, the above-mentioned "slightly negative pressure state" means that the air outlet volume is slightly larger than the air intake volume, so that the air pressure in the first chamber and the second chamber is lower than the external atmospheric pressure, thereby forming a slightly negative pressure state in the first chamber and the second chamber.

[0030] Exemplarily, the first exhaust assembly 30 is used to discharge the gas in the first chamber from the first air outlet, and the second exhaust assembly 40 is used to discharge the gas in the second chamber from the second outlet.

[0032] In one embodiment, the structure of the second exhaust assembly 40 is the same as that of the first exhaust assembly 30.

[0033] Since the structures of the first exhaust assembly 30 and the second exhaust assembly 40 are the same, for the convenience of description, the following takes the first exhaust assembly 30 as an example for specific description. The structure of the second exhaust assembly 40 can refer to the following first exhaust assembly 30, specifically:

One end of the cylinder is embedded in the first air outlet and communicated with the first chamber, and the fan is arranged inside the cylinder for accelerating the air flow in the first chamber to flow out from the first air outlet, so as to maintain a micro-negative pressure state in the first chamber.

[0035] It should be noted that the structure in which the fan is rotatably arranged inside the cylinder is a conventional choice for those skilled in the art, and can specifically refer to the prior art, which will not be elaborated here.

[0036] Exemplarily, the fan is rotatably arranged inside the cylinder, and one end of the cylinder is embedded in the first air outlet and communicated with the first chamber, so that under the drive of the fan, the air flow in the first chamber can be accelerated to flow out from the first air outlet, and the air volume flowing out from the first air outlet is greater than the air volume of the first air inlet 10a, thereby ensuring that a micro-negative pressure state can be maintained in the first chamber.

[0038] In one embodiment, at least two limiting strips 100 extend outward from the surface of the fixing frame 50 facing the cylinder body. The two limiting strips 100 are symmetrically distributed along the radial direction of the cylinder body, and a clamping space 110 for clamping the cylinder body is formed between the two limiting strips 100.

[0039] In one embodiment, moving wheels 60 are connected to the bottoms of the first box body 10 and the second box body 20. In this way, the first box body 10 and the second box body 20 can be moved by using the moving wheels 60, which is convenient for subsequent assembly or disassembly.

The first cover plate 70 is used to cover the first chamber, and a first air inlet 10a is provided at the lower part of the first cover plate 70; and / or, a second cover plate 80 is openably provided on the front surface of the second box body 20. The second cover plate 80 is used to cover the second chamber, and a second air inlet 20a is provided at the lower part of the second cover plate 80. In this way, the first chamber and the second chamber can be covered in an openable manner by using the first cover plate 70 and the second cover plate 80. When the electrolytic cell needs to be replaced, only the first cover plate 70 needs to be pulled open so that the first chamber is exposed, and then the electrolytic cell placed in the first chamber can be quickly replaced.

[0042] In one embodiment, holding blocks 90 are provided on the first cover plate 70 and / or the second cover plate 80. In this way, it is convenient for the operator to hold the holding blocks 90 to open the first cover plate 70 or the second cover plate 80.
