A liquid storage cavity 23 is formed between an outer wall surface of the side wall 221 and an inner wall surface of the shell 1 for storing the aerosol generating substrate. A through hole 222 is provided on the side wall 221 of the connecting pipe 22 opposite to the vaporization core 21. The aerosol generating substrate located in the liquid storage cavity 23 enters the vaporization core 21 through the through hole 222. The vaporization core 21 heats and vaporizes the aerosol generating substrate to generate aerosols. Finally, the aerosols flow to the air outlet channel 120 through the vaporization channel 210 and are discharged through air outlet 121.

In addition, the liquid Date Recue/Date Received 2023-09-13 guide member 24 may store a specific amount of aerosol generating substrates to facilitate rapid supply to the vaporization core 21 for heating, thereby effectively improving vaporization efficiency.

[0043] Referring to FIG. 3, in some embodiments, the electrode component 3 includes a fixed base 31, a first electrode 32, and a second electrode 33. The fixed base 31 may be made of a hard and insulating material. The first electrode 32 and the second electrode 33 are insulated from each other by the fixed base 31. The external diameter of the fixed base 31 is less than the internal diameter of the connecting pipe 22, and the fixed base 31 is at least partially mounted in the connecting pipe 22.

[0044] The fixed base 31 is at least partially sleeved on the vaporization component 2, and the fixed base 31 is at least partially sleeved on the first electrode 32. The second electrode 33 is sleeved outside the fixed base 31. The first electrode 32 and the second electrode 33 are insulated from each other by the fixed base 31. In some embodiments, the first electrode 32 may be hollow and cylindrical, and has an intermediate airway 320 formed therein. The intermediate airway 320 is in communication with the vaporization channel 210.
The external diameter of the first electrode 32 is less than the internal diameter of the fixed base 31, so that the first electrode 32 may be mounted inside the fixed base 31.

[0045] Referring to FIG. 3 to FIG. 5, in some embodiments, a silicone ring 34 may be arranged between the first electrode 32 and the fixed base 31, and the silicone ring 34 may be hollow and cylindrical. The external diameter of the silicone ring 34 is equivalent to the external diameter of an end of the fixed base 31 close to the air outlet 121, and the end of the fixed base 31 close to the air outlet 121 abuts against the second electrode 33.

[0046] In this way, external air may enter the vaporization channel 210 inside the vaporization core 21 through the intermediate airway 320 of the first electrode 32, then flow to the air outlet channel 120 together with the aerosols generated through heating by the vaporization core 21, and finally be discharged through the air outlet 121 for inhalation by a user.

[0047] With reference to FIG. 2 and FIG. 3, an air channel 30 is formed between the first electrode 32 and the fixed base 31. The air channel 30 is in communication with the vaporization channel 210 inside the vaporization core 21. In some embodiments, an air groove is provided on an inner wall surface of the fixed base 31. The first electrode 32 is arranged in Date Recue/Date Received 2023-09-13 the fixed base 31. The air channel 30 is formed between the first electrode 32 and the air groove.
In this way, the external air may enter the vaporization channel 210 through the intermediate airway 320 of the first electrode 32, or may enter the vaporization channel 210 through the air channel 30 formed between the first electrode 32 and the fixed base 31, thereby increasing an air intake volume and improving the vaporization efficiency.

[0048] As shown in FIG. 3, in some embodiments, the second electrode 33 includes a first connection portion 331 and a second connection portion 332. The first connection portion 331 is detachably sleeved on the fitting end 11, and the second connection portion 332 is connected to the first connection portion 331 and protrudes from the shell 1. An air inlet hole 333 is arranged on the second electrode 33. The air inlet hole 333 is located in a circumferential direction of the second electrode 33, and the air inlet hole 333 is in communication with the air channel 30. Moreover, with reference to FIG. 2 and FIG. 3, parts of the second connection portion 332 and the fixed base 31 that are not inserted into the connecting pipe 22 are arranged spaced apart from each other. The air entering the air hole may arrive at an end portion of the fixed base 31 by passing through a gap between the second connection portion 332 and the fixed base 31, and then enter the air channel 30 between the fixed base 31 and the first electrode 32.

[0049] As shown in FIG. 2, in some embodiments, the second electrode 33 is sleeved between the connecting pipe 22 and an inner wall of the fitting end 11, and the first electrode 32 and the second electrode 33 are both connected to an electrode of the vaporization core 21.
Referring to FIG. 3 to FIG. 6, in some embodiments, the vaporization core 21 has a first electrode pin 321 and a second electrode pin 322. The first electrode pin 321 is electrically connected to the first electrode 32, and the second electrode pin 322 is electrically connected to the second electrode 33. The first electrode pin 321 and the second electrode pin 322 respectively abut against an inner wall and an outer wall of the fixed base 31, to sleeve and space apart the first electrode pin 321 and the second electrode pin 322 on the fixed base 31.
Moreover, the first electrode pin 321 abuts against the inner wall of the fixed base 31 and contacts the first electrode 32 sleeved inside the fixed base 31, thus implementing electrical connection between the first electrode pin 321 and the first electrode 32. The second electrode pin 322 abuts against the outer wall of the fixed base 31. When the fixed base 31 is inserted into the connecting pipe 22, the second electrode pin 322 may contact the connecting pipe 22.
Then the second electrode 33 is sleeved between the connecting pipe 22 and the fitting end 11 Date Recue/Date Received 2023-09-13 of the shell 1. In this way, through electrical connection of the connecting pipe 22 to the second electrode pin 322 and the second electrode 33, connection between the second electrode 33 and the second electrode pin 322 is achieved. In some embodiments, the connecting pipe 22 is a conductive member.

[0050] As shown in FIG. 4, FIG. 6, and FIG. 8, in some embodiments, a plurality of protrusions 4 are arranged on the fixed base 31, and a groove 40 is formed between two adjacent protrusions 4. Therefore, a plurality of grooves 40 are formed among the plurality of protrusions 4. The groove 40 may be configured for the first electrode pin 321 and the second electrode pin 322 of the vaporization core 21 to be mounted therein. During fitting of the vaporization core 21 to the fixed base 31, the first electrode pin 321 is guidable and mountable in one of the plurality of grooves 40, and the second electrode pin 322 is guidable and mountable in another of the plurality of grooves 40. It may be understood that the first electrode pin 321 and the second electrode pin 322 are respectively guided and mounted in two independent grooves of the plurality of grooves 40, and other grooves 40 having no electrode pins accommodated therein may be configured to increase the air intake amount.

[0051] In some embodiments, the plurality of protrusions 4 may be arranged on the outer wall surface of the fixed base 31. In some embodiments, the plurality of protrusions 4 may be arranged parallel to an axis of the fixed base 31, so that the formed grooves 40 are parallel to the axis of the fixed base 31, thereby facilitating mounting of the first electrode pin 321 and the second electrode pin 322. In some embodiments, each of the plurality of protrusions 4 is arranged to extend from an end thereof close to the air outlet 121 toward an other end thereof away from the air outlet 121, to facilitate guidance for the mounting of the first electrode pin 321 and the second electrode pin 322 from the ends thereof close to the air outlet 121 to the ends thereof away from the air outlet 121.

[0052] As shown in FIG. 6, in some embodiments, the diameter of an end of each of the plurality of protrusions 4 close to the air outlet 121 is less than the diameter of an end thereof away from the air outlet 121. In some embodiments, the plurality of protrusions 4 are substantially V-shaped. The diameter of each of the plurality of protrusions 4 gradually increases from an end thereof close to the air outlet 121 toward an other end thereof away from the air outlet 121. In this way, an end of the formed groove 40 close to the air outlet 121 has a larger diameter, facilitating guidance for the mounting. In addition, the diameter of the groove 40 gradually decreases from the end thereof close to the air outlet 121 to the end thereof away Date Recue/Date Received 2023-09-13 from the air outlet 121. In this way, during the fitting, the first electrode pin 321 and the second electrode pin 322 can be guided into the groove 40, and the first electrode pin 321 and the second electrode pin 322 can be squeezed when mounted to the ends of the grooves away from the air outlet 121, thereby causing the second electrode pin 322 to be attached and electrically connected to the connecting pipe 22.

[0053] As shown in FIG. 6 and FIG. 7, in some embodiments, the fixed base 31 is cylindrical. The fixed base 31 includes a first cylinder segment 311 close to an end of the air outlet 121 and a second cylinder segment 312 extending away from the end of the air outlet 121 along the first cylinder segment 311. The second cylinder segment 312 is connected to the first cylinder segment 311. Each of the plurality of protrusions 4 is distributed on the first cylinder segment 311 and the second cylinder segment 312. In some embodiments, each of the plurality of protrusions 4 extends from an end of the first cylinder segment 311 close to the air outlet 121 toward an other end thereof away from the air outlet 121, and each of the plurality of protrusions 4 extend from an end of the second cylinder segment 312 close to the air outlet 121 toward an other end thereof away from the air outlet 121.

[0054] In some embodiments, the external diameter of the first cylinder segment 311 is less than or equal to the external diameter of the second cylinder segment 312.
When the external diameter of the first cylinder segment 311 is less than the external diameter of the second cylinder segment 312, the first cylinder segment 311 serves as a pre-mounted segment for the fixed base 31, which facilitates mounting of the fixed base 31 to the connecting pipe 22. Due to the smaller external diameter of the first cylinder segment 311, when the first cylinder segment 311 enters the connecting pipe 22, the external diameter of the first cylinder segment 311 does not press against the second electrode pin 322 located on the outer wall surface of the fixed base 31, thereby facilitating fitting. At this time, the first electrode pin 321 and the second electrode pin 322 are already located in groove position of the grooves 40, which achieves preliminary fitting of the fixed base 31. After the preliminary fitting of the fixed base 31 is completed, the second cylinder segment 312 can be conveniently fitted to the connecting pipe 22 to rivet the fixed base 31 into the connecting pipe 22.

[0055] In some embodiments, a first limiting portion 41 is arranged on an end of each of the plurality of protrusions 4 away from the air outlet 121. The first limiting portion 41 extends outward in a direction perpendicular to an axis of the fixed base 31, and is configured to be fitted to the connecting pipe 22 for position limitation.

[0056] As shown in FIG. 5, in some embodiments, a plurality of longitudinal positioning ribs 313 are arranged on the inner wall surface of the fixed base 31, and are configured to be fitted to the first electrode 32. The positioning ribs 313 are arranged on the inner wall surface of the fixed base 31 in a direction parallel to an axis of the fixed base 31 fit with the first electrode 32. In some embodiments, the positioning ribs 313 may be uniformly distributed on the inner wall surface of the fixed base 31 at intervals. In some embodiments, the positioning ribs 313 located on the inner wall surface of the fixed base 31 may not be unifolinly distributed, and the air groove is partially arranged on the inner wall surface of the fixed base 31 to form the air channel 30 with the groove 40.

[0057] In some embodiments, a second limiting portion 3131 is arranged on each of the positioning ribs 313, and is configured to be fitted to the first electrode 32 for position limitation. The second limiting portion 3131 is arranged on an end of the positioning rib 313 close to the air outlet 121. The second limiting portion 3131 extends inward in the direction perpendicular to the axis of the fixed base 31. The first electrode 32 is mounted into the fixed base 31 from an end of the fixed base 31 away from the air outlet 121, and the second limiting portion 3131 can prevent the first electrode 32 from moving upward and extending out of the fixed base 31 in an axial direction.

[0058] In some embodiments, the positioning rib 313 includes a first segment 3132 close to the air outlet 121 and a second segment 3133 connected to the first segment 3132. The inner diameter of the second segment 3133 is greater than the inner diameter of the first segment 3132, so that the second segment 3133 serves as a pre-mounted segment for the first electrode 32. In this case, since the inner diameter of the second segment 3133 is greater than the inner diameter of the first segment 3132, the first electrode 32 may be pre-mounted into the second segment 3133 and subsequently mounted into the first segment 3132.

[0059] In some embodiments, the plurality of protrusions 4 may be arranged on the inner wall surface of the fixed base 31. Preferably, the plurality of protrusions 4 may be arranged on both the inner wall surface and the outer wall surface of the fixed base 31.
The first electrode pin 321 may be guided and mounted into the groove 40 located on the inner wall surface of the fixed base 31, and the second electrode pin 322 may be guided and mounted into the groove 40 located on the outer wall surface of the fixed base 31. Since a large number of protrusions 4 are arranged and the plurality of protrusions 4 surround the fixed base 31, accurate alignment is not required, and the first electrode pin 321 and/or the second electrode pin 322 can be Date Recue/Date Received 2023-09-13 conveniently guided into the groove 40. Therefore, the mounting is convenient.
At least two protrusions 4 are arranged, to ensure that at least two grooves 40 may be formed for the electrode pins to be mounted. The number of protrusions may be adjusted according to an actual condition, and is not specifically limited herein.

[0060] As shown in FIG. 8, in some embodiments, the plurality of protrusions 4 are symmetrically distributed on an upper end and a lower end of the fixed base 31 in an axial direction. Upper and lower positions of the fixed base 31 do not need to be defined, which simplifies the fitting process.
