[0024] Embodiment 1

[0025] As Figures 1 to 2 shown, in this embodiment, an activated carbon cartridge is provided, which includes an inner cylinder 2, an outer cylinder 1, activated carbon 3 and an end sealing assembly. The inner cylinder 2 is sleeved inside the outer cylinder 1. Mesh holes are provided on the surfaces of the inner cylinder 2 and the outer cylinder 1. The mesh holes of the inner cylinder 2 and the outer cylinder 1 are processed by a metal stamping and stretching forming process. The two ends of the inner cylinder 2 and the outer cylinder 1 are respectively sealed and connected by an end sealing assembly to form an annular ventilation cavity. Activated carbon 3 is filled in the annular ventilation cavity. One of the end sealing assemblies is detachably connected to the mounting seat 9. Among them, the mesh holes of the inner cylinder 2 and the outer cylinder 1 are processed by a metal stamping and stretching forming process, preferably by stamping and stretching a steel plate, which saves more materials, has a smaller wind resistance and a lower cost.

[0026] As an alternative solution, in this embodiment, the end sealing assembly includes an upper sealing assembly and a lower sealing assembly. The upper sealing assembly is arranged at the upper end of the outer cylinder 1, and the lower sealing assembly is arranged at the lower end of the outer cylinder 1 to seal the annular ventilation cavity and the activated carbon 3.

[0027] As an alternative solution, in this embodiment, the upper sealing assembly includes a connecting ring 4 and a sealing cover 5. The connecting ring 4 is welded to the end of the outer cylinder 1. The sealing cover 5 is embedded in the connecting ring 4 and the side wall is connected to the connecting ring 4 by bolts 8 to form an integral cartridge.

[0028] As an alternative solution, in this embodiment, a circular groove is provided at the lower end of the sealing cover 5. The groove of the sealing cover 5 is inserted into the upper opening of the annular ventilation cavity and connected to the outer cylinder 1 by bolts 8 to form an integral cartridge. The height of the sealing cover 5 is 5 mm - 20 mm, preferably 16 mm. In this embodiment, there are two ways to make the sealing cover 5, a circular sealing plug-in cover, which seals the outer end of the cartridge and the air flow is discharged from the outer cylinder 1.

[0029] As an alternative, in this embodiment, the sealing cover 5 is made of stainless steel or galvanized iron sheet.

[0030] As an alternative, in this embodiment, the lower sealing assembly includes a base 6 and a gasket 7. An outer cylinder 1 is welded to the outer circle of the base 6, and an inner cylinder 2 is welded to the inner circle. The gasket 7 is connected to the bottom surface of the base 6 by bolts 8 and locked with the base 6 to form the overall carbon cylinder. The bolt head of the bolt 8 protrudes from the bottom surface of the base 6, and the bolt head of the bolt 8 is movably clamped in the card slot 10 of the mounting seat 9. By rotation, the bolt head can be stuck in the gourd-shaped card slot 10 to complete the assembly of the entire carbon cylinder filled with activated carbon 3 and the mounting seat 9.

[0031] As an alternative, in this embodiment, the gasket 7 is made of ethylene-vinyl acetate copolymer foamed sponge, which can prevent gas and activated carbon 3 from leaking.

[0032] As an alternative, in this embodiment, at least one ventilation hole is provided on the mounting seat 9, and a card slot 10 is provided on the ventilation hole for connecting the bolt head of the bolt 8 to facilitate disassembly and assembly.

The mesh ratio is large and the air permeability effect is good. Among them, the mesh is preferably a diamond hole, and the width dimension of the diamond hole is between 1.5 - 3 mm, and the length dimension is between 4 - 8 mm, ensuring the maximum ventilation efficiency while preventing the leakage of activated carbon 3.

[0034] As an alternative, in this embodiment, the activated carbon 3 is a carbon rod with a diameter of 2 mm - 6 mm and a length greater than 3 mm. The diameter is larger than the mesh width to prevent material leakage, thus playing a role in purifying the air.

[0035] In this embodiment of the activated carbon cylinder, the air flow enters the inner cylinder 2 from the ventilation hole on the mounting seat 9, and is discharged from the outer cylinder 1 after being filtered by the activated carbon, thus playing a role in purifying the air.
