In this embodiment, the housing 110 forms a mounting step 1102 inside the opening 1101, the mounting step 1102 is used for mounting the sealing sheet 112, the mounting step 1102 is perpendicular to the axial direction of the housing 110 and is continuous in the circumferential direction of the housing 110, the mounting step 1102 divides the opening 1101 into a reservoir 1103 and a mounting cavity 1104 along the axial direction of the housing 110, the reservoir 1103 is located at a side of the opening 1101 close to the mouthpiece component 50 and is bounded by the mounting step 1102, the reservoir 1103 is used for storing smoke liquid, the mounting cavity 1104 is located at a side of the opening 1101 far from the mouthpiece component 50 and is bounded by the mounting step 1102, the mounting cavity 1104 is used for matching the puncturing component 13, the periphery of the sealing sheet 112 is fixedly connected with the mounting step 1102, the sealing sheet 112 seals the reservoir 1103, and the connection mode of the sealing sheet 112 and the mounting step 1102 includes, but is not limited to, high temperature hot.

The spike assembly 13 is coupled to the housing 110, and the atomizing assembly 15 is coupled to the spike assembly 13 and positioned in the path of the smoke fluid flowing out of the reservoir 1103. Wherein, the puncturing assembly 13 is capable of moving unidirectionally relative to the housing 110 from a sealing position spaced from the sealing sheet 112 to a puncturing position for puncturing the sealing sheet 112, and the sealing sheet 112 is punctured when the puncturing assembly 13 moves to the puncturing position, so that the reservoir 1103 is communicated with the atomizing assembly 15.

Referring to fig. 4 and 5, in particular, one of the housing 110 and the puncturing assembly 13 is provided with a first fastening portion 1321, and the other is provided with a first matching portion 1105 for limiting the first fastening portion 1321 to move only in a single direction along the puncturing direction, so that the puncturing assembly 13 can puncture the sealing sheet 112 when moving from the sealing position to the puncturing position in the single direction along the puncturing direction under the action of an external force, and is fixed relative to the housing 110 through the matching of the first fastening portion 1321 and the first matching portion 1105 after puncturing, thereby satisfying the subsequent normal use of the cartridge 10.

When the sealing cylinder 135 is sleeved outside the puncturing element 132, the fourth limiting step 1328 is caught by the limiting groove 1357, so that the sealing cylinder 135 is fixed on the puncturing element 132 and moves together with the puncturing element 132 along the puncturing direction with respect to the housing 110.

The atomizing assembly 15 includes a liquid guiding member 150 and a heat generating member 152, the heat generating member 152 is disposed on one surface of the puncturing member 132 facing the base 130, the heat generating member 150 is disposed transversely at one end of the communicating chamber 1329, and two opposite ends of the heat generating member are disposed in the two electrode mounting holes 1327, where "transversely" is defined as being disposed parallel to the surface of the puncturing member 132 facing the base 130, and the liquid guiding member 150 is supported on the heat generating member 152 and is accommodated in the communicating chamber 1329. Specifically, the cartridge 10 includes a first electrode contact 17 and a second electrode contact 19, and the heating element 152 is U-shaped with an opening facing the communication cavity 1329, that is, the heating element 152 is sheet-shaped, and both ends of the heating element 152 are bent in a direction facing the electrode mounting hole 1327. When the first electrode contact 17 and the second electrode contact 19 are respectively mounted in the two electrode mounting holes 1327, one end of the heat generating member 152 is inserted and held between the first electrode contact 17 and the hole wall of the corresponding electrode mounting hole 1327, and the other end of the heat generating member 152 is inserted and held between the second electrode contact 19 and the hole wall of the corresponding electrode mounting hole 1327. So, on the one hand realize the convenience of generating heat the piece 152 assembly, on the other hand is convenient for generate heat subsequent dismouting and maintenance of piece 152.

A first limiting step 1317 is formed on the inner hole wall of each stepped hole 1307, so that each stepped hole 1307 is in a step shape with a wide bottom and a narrow top, that is, one end of each stepped hole 1307 close to the puncturing piece 132 is narrower than one end of each stepped hole 1307 far away from the puncturing piece 132. Meanwhile, a second limit step 1326 is formed on the inner hole wall of each of the electrode mounting holes 1327 such that each of the electrode mounting holes 1327 is stepped in a narrow-down and wide-up manner, i.e., one end of each of the electrode mounting holes 1327 near the base 130 is narrower than one end thereof far from the base 130. It is understood that in other embodiments not shown, the stepped bore 1307 on the base 130 may also be a straight bore, i.e., there is no step or step within the stepped bore 1307. Correspondingly, the first electrode contact 17 is fitted to the tail end of the stepped hole 1307 to form a first fitting step 170 which is fitted with the first limit step 1317, and the first electrode contact 17 is fitted to the head end of the electrode fitting hole 1327 to form a second fitting step 172 which is fitted with the second limit step 1326. Thus, when the second engaging step 172 at the head end of the first electrode contact 17 is fastened to the second limiting step 1326, the first engaging step 170 at the tail end of the first electrode contact 17 is synchronously abutted to the first limiting step 1317 and cannot move forward any more, so that the stroke of the first electrode contact 17 is limited and the first electrode contact 17 is prevented from sliding out of the corresponding electrode assembling hole 1327.

Referring to fig. 7, in the present embodiment, a third limiting step 171 is formed between the first mating step 170 and the second mating step 172 of the first electrode contact 17 and protrudes outward along the radial direction of the first electrode contact 17, and a surface of the third limiting step 171 away from the upper surface 1301 abuts against a surface of the main body 1324 facing the upper surface 1301. Thus, when the first electrode contact 17 is mounted in the electrode mounting hole 1327, the surface of the third limiting step 171 of the first electrode contact 17 away from the upper surface 1301 supports against the surface of the heat generating member 152 facing the upper surface 1301 and cannot move forward any more, so that the stroke of the first electrode contact 17 is limited, and the heat generating member 152 is prevented from sliding out of the corresponding electrode mounting hole 1327. Similarly, the second electrode contact 19 is also provided with the same structure as the first electrode contact 17, and is not described herein again. Referring to fig. 13, further, the base 130 includes a first side 1302 and a second side 1304 disposed opposite to the first side 1302, wherein a direction perpendicular to both the first side 1302 and the second side 1304 is defined as a transverse direction, a direction perpendicular to both the axial direction and the transverse direction is defined as a longitudinal direction, and an upper surface 1301 of the base 130 is recessed along the transverse direction to form a notch 1306 penetrating through the first side 1302 and the second side 1304. The first side 1302 and the second side 1304 are narrow sides.

Referring to fig. 7 and 8, further, the housing 110 has an air inlet hole 1107 corresponding to one of the first side surface 1302 and the second side surface 1304 and an air flow channel 1109 corresponding to the other of the first side surface 1302 and the second side surface 1304, that is, one side surface of the housing 110 in the transverse direction has the air inlet hole 1107, and the other side surface of the housing in the transverse direction has the air flow channel 1109. The airflow channel 1109 is separated from the reservoir 1103, and the airflow channel 1109 is connected between the inlet 1107 and the mouthpiece component 50. Referring to fig. 4 and 7, material is removed from one lateral side of the housing 110 to form a gas flow channel 1109 penetrating through the surface of the housing 110 away from the upper surface 1301 to the surface close to the upper surface 1301, and a second mounting step 1106 is formed at one end of the gas flow channel 1109 close to the upper surface 1301.
