The tube 10 further includes an outer tube 70, a sealing part 30, a sealing part 80, a filter part 50, and a packing part 60. Wherein the sealing part 30 is used for sealing one end of the outer tube 70. The tobacco unit 20 is received in one end of the outer tube 70 near the seal 30. The tube 10 is received in the outer tube 70 and is disposed adjacent to the tobacco unit 20. The sealing part 80 is arranged at least at one end of the two ends of the tube body 10, which are arranged oppositely, and the sealing part 80 is at least arranged at one end of the tube body 10, which is close to the tobacco unit 20. The filter portion 50 is received in the outer tube 70 and is disposed adjacent to the tube 10 and away from the tobacco unit 20 relative to the tube 10. The wrapping portion 60 is disposed around the outer tube 70 to wrap the outer tube 70.

Although embodiments of the present application have been shown and described, it is understood that the above embodiments are illustrative and not restrictive, and that those skilled in the art may make changes, modifications, substitutions and alterations to the above embodiments without departing from the scope of the present application, and that such changes and modifications are also to be considered as within the scope of the present application.
