Abstract (en)
[origin: EP4218432A1] The present invention discloses a particle-type cigarette wherein downstream of a particle section is magnetically sealed, the cigarette comprises a paper tube (5), a sealing film (1) that blocks the distal lip end of the paper tube (5), a particle filling section located immediately downstream of the sealing film (1), the particle filling section accommodates uniformly mixed tobacco particles (2) and susceptor particles (3), a magnet chip bridging layer (9) is located immediately downstream of the particle filling section, the magnet chip bridging layer (9) is circumferentially magnetically fixed to the wall-attached iron foil ring (4) on the inner surface of or inside the side wall of the paper tube (5) , the downstream of the magnet chip bridging layer (9) is successively the cavity section (7) and the filter section (8). The present invention also discloses a manufacturing method of the particle-type cigarette wherein downstream of a particle section is magnetically sealed.
