During operation, the liquid guiding element 142 can conduct the smoke liquid in the liquid guiding hole 1421 to the atomizing surface 1423 of the liquid guiding element 142 to contact the heating element 141, and the smoke is atomized under the heating action of the heating element 141. When a user performs a suction operation, the external air flowing through the inner cavity of the electrode column 13 flows out from the air gaps on both sides of the liquid guiding element 142, and the smoke generated on the corresponding side is taken out after passing through the heating element 141, where the direction indicated by the arrow in fig. 9 is the air flowing direction. Compared with the first embodiment, the atomizing head 10 of the second embodiment changes the position of the heating element 141 from the lower end of the liquid guiding element 142 to the side wall of the liquid guiding element 142, and changes the arrangement of the heating element 141 on one end surface into the arrangement of the heating elements 141 on two end surfaces, so that the contact area between the heating element 141 and the liquid guiding element 142 is increased, the atomizing effect is improved, meanwhile, the uniformity of smoke generated on two sides of the liquid guiding element 142 is ensured, and the smoking taste of a user is improved. It should be noted that the structures of the heating element 14 in the second embodiment and the first embodiment may be replaced with each other.

In a specific embodiment, the two atomizing surfaces 1423 are symmetrically disposed about the liquid guiding hole 1421, so that the shortest conducting distance d2 from the hole wall of the liquid guiding hole 1421 to the atomizing surface 1423 for the smoke liquid entering the liquid guiding hole 1421 is the same, which ensures the uniformity of the smoke liquid conducted to the two atomizing surfaces 1423, and makes the atomization more uniform.

In the present embodiment, the liquid guide surface 1422 of the liquid guide element 142 is spaced apart from the inner wall of the atomizing sleeve 11, the sealing member 15 is interposed between the liquid guide surface 1422 and the inner wall of the atomizing sleeve 11, the communication hole 153 is formed in the sealing member 15, and both ends of the communication hole 153 communicate with the liquid guide hole 1421 and the liquid inlet hole 111, respectively, so that the smoke liquid in the liquid storage chamber 201 sequentially enters the liquid guide hole 1421 through the liquid inlet hole 111 and the communication hole 153.

Referring to fig. 10 again, in one embodiment, the sealing member 15 has mounting grooves 155 formed on two opposite sidewalls thereof, which are offset from the communication holes 153, and the user mounts the heating element 141 in the sealing member 15 through the mounting grooves 155. It should be noted that, after the heating element 141 is mounted in place, one end of the pin of the heating element 141 extends out of the sealing member 15, and then two pins of the heating element 141 are bent to facilitate pin connection.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
