Refer to FIG. 1 to FIG. 4. The vaporizer 100 in the embodiments of this application includes a vaporization cartridge 10, a mouthpiece component 30, and a connector 50. The vaporization cartridge 10 is mounted in the mouthpiece component 30, to enable aerosols generated by the vaporization cartridge 10 to flow out through the mouthpiece component 30. The vaporization cartridge 10 includes a cartridge tube 11 and a vaporization assembly 13. The cartridge tube 11 is provided with a liquid storage cavity 1101 (shown in FIG. 6). The vaporization assembly 13 is inserted in the cartridge tube 11. A part of the vaporization assembly 13 is located in the liquid storage cavity 1101. A first end 1301 of the vaporization assembly 13 is communicated with the outside. A second end 1303 of the vaporization assembly 13 is provided with a connection portion 15. The connector 50 is separately fitted to the connection portion 15 and the mouthpiece component 30, to enable the vaporization cartridge 10 to be mounted in the mouthpiece component 30.

The aerosols are multiphase fluids with a continuous phase in a gaseous state and a dispersed phase in solid and liquid states. In some embodiments, a vaporization medium may be a vaporization medium carrier carrying a mixed solution. Solutes in the mixed solution may include nicotine, nicotine salts, and plant extracts, and the solvents in the mixed solution can be common organic solutes and/or inorganic solutes such as propylene glycol, vegetable glycerin and pure water. The vaporization cartridge 10 can disperse the mixed solution into tiny droplets and the droplets are mixed with air to form aerosols. In some other embodiments, the vaporization medium is a solid vaporization medium, such as a leafy vaporization medium. The vaporization cartridge 10 can perform operations, such as heating, on the leafy vaporization medium, to enable the leafy vaporization medium to volatilize tiny solid particles, which are mixed with air to form aerosols.

In the vaporizer 100 of this application, the vaporization cartridge 10 stores the vaporization medium, and the vaporization cartridge 10 is provided with the connection portion 15 connected to other structures. After the vaporization medium in the vaporization cartridge 10 is used out, a user only needs to replace the vaporization cartridge 10 with a new vaporization cartridge, and other parts of the vaporizer 100 can continue to be used. Therefore, the user can easily add the vaporization medium into the vaporizer 100 by replacing the vaporization cartridge 10.

The following further describes the vaporizer 100 with reference to the accompanying drawings.

Refer to FIG. 5 and FIG. 6. In some embodiments, the cartridge tube 11 is a structure sleeved outside the vaporization assembly 13.

The cartridge tube 11 not only participates in forming the liquid storage cavity 1101, in another aspect, but also can protect the vaporization assembly 13 accommodated inside the cartridge tube 11.

Specifically, in some embodiments, the cartridge tube 11 includes a housing 111 and a plugging member 113. The housing 111 is roughly a cylindrical structure with two open ends. Therefore, the housing 111 has an outer wall and an inner wall facing away from each other. The cross-sectional shape of the housing 111 includes, but is not limited to, a circle, an oval, a triangle, a quadrilateral, a pentagon, a hexagon, and the like. The material of the housing 111 includes, but is not limited to, plastic, metal, acrylonitrile-butadiene-styrene copolymer (ABS resin), and the like.

More specifically, with reference to FIG. 4, in some embodiments, the housing 111 includes a first end 1111 and a second end 1113 opposite to each other. The vaporization assembly 13 passes through the housing 111, and the first end 1301 of the vaporization assembly 13 extends out of the liquid storage cavity 1101 through the first end 1111 of the housing 111. The connection portion 15 disposed at the second end 1303 of the vaporization assembly 13 extends out of the liquid storage cavity 1101 through the second end 1113 of the housing 111.

Further, in some embodiments, there is a gap between the vaporization assembly 13 and the inner wall of the housing 111 to accommodate a vaporization medium. In some other embodiments, the vaporization assembly 13 abuts against the inner wall of the housing 111 to make the structure of the vaporization cartridge 10 stable and not prone to deformation.

Still further, in some embodiments, the inner contour dimension of the cross-section of the housing 111 gradually decreases in the direction from the second end 1113 of the housing 111 to the first end 1111 of the housing 111. Therefore, the inner wall of the housing 111 forms an inward inclined arc, so that more liquid is stored in the part of the liquid storage cavity 1101 close to the second end 1113 of the housing 111, thereby facilitating vaporization of the vaporization medium by the vaporization assembly 13. In some other embodiments, the inner contour dimension of the cross-section of the housing 111 remains unchanged in the direction from the second end 1113 of the housing 111 to the first end 1111 of the housing 111. Compared with the solution in which the inner contour dimension of the cross-section of the housing 111 gradually decreases, the liquid storage cavity 1101 formed in the housing 111 in the embodiments has a larger volume, and can store more vaporization medium, so that the quantity of times the vaporization cartridge 10 can be used is increased.

Furthermore, an anti-slip portion 115 is provided at a position on the outer wall of the housing 111 close to the second end 1113 of the housing 111. The anti-slip portion 115 can increase roughness of a contact surface between a user and the outer wall of the housing 111, so that the user can mount or remove the vaporization cartridge 10 with less effort. In some embodiments, the anti-slip portion 115 and the housing 111 are integrally formed. The anti-slip portion 115 is a pattern formed on the outer wall of the housing 111. The shape of the pattern includes, but is not limited to, protrusions, grooves, recesses, and the like. In some other embodiments, the anti-slip portion 115 and the housing 111 are separately formed. The anti-slip portion 115 is sleeved on the outer wall of the housing 111. In one example, the anti-slip portion 115 is detachably mounted on the outer wall of the housing 111. The mounting manner includes, but is not limited to, snap-fit connection, threaded connection, and the like. In another example, the anti-slip portion 115 is non-detachably fixed to the outer wall of the housing 111. The fixation manner includes, but is not limited to, fixation by welding, fixation by interference-fit, fixation by gluing, and the like.

Refer to FIG. 5 and FIG. 6. In some embodiments, the plugging member 113 is a structure that participates in forming the liquid storage cavity 1101.

The first end 1301 of the vaporization assembly 13 (shown in FIG. 4) passes through the plugging member 113 and extends out of the liquid storage cavity 1101. The plugging member 113, the inner wall of the housing 111, and the outer wall of the part of the vaporization assembly 13 located in the housing 111 together form the liquid storage cavity 1101.

The plugging member 113 may be fitted to the first end 1111 of the housing 111 to seal the first end 1111 of the housing 111. The outer contour shape of the cross-section of the plugging member 113 matches the inner contour shape of the cross-section of the first end 1111 of the housing 111, to enable the vaporization medium to be completely sealed in the liquid storage cavity 1101. The cross-sectional shape of the plugging member 113 includes, but is not limited to, a circle, an oval, a triangle, a quadrilateral, a pentagon, a hexagon, and the like. The material of the plugging member 113 includes, but is not limited to, rubber, silicone, plastic, and the like.

Specifically, in some embodiments, the outer contour dimension of the cross-section of the plugging member 113 is adapted to the inner contour dimension of the cross-section of the first end 1111 of the housing 111, and at least part of the structure of the plugging member 113 is located inside the housing 111.

In some other embodiments, the plugging member 113 is located at the outside of the housing 111. A mounting groove is provided at the side of the plugging member 113 close to the first end 1111 of the housing 111, and the inner contour dimension of the cross-section of the mounting groove is adapted to the outer contour dimension of the cross-section of the first end 1111 of the housing 111, to enable the plugging member 113 to be sleeved on the first end 1111 of the housing 111, and the end face of the first end 1111 of the housing 111 to abut against with the bottom wall of the mounting groove.

More specifically, in some embodiments, the height of the side surface of the plugging member 113 facing toward the outside of the liquid storage cavity 1101 is the same as that of the end face of the first end 1111 of the housing 111, to facilitate mounting of the vaporization cartridge 10 to other structures. In some other embodiments, the height of the side surface of the plugging member 113 facing toward the outside of the liquid storage cavity 1101 is different from that of the end face of the first end 1111 of the housing 111. In one example, the plugging member 113 is completely accommodated inside the housing 111, and compared with the end face of the first end 1111 of the housing 111, the side surface of the plugging member 113 facing toward the outside of the liquid storage cavity 1101 is closer to the second end 1113 of the housing 111. The part of the structure of the vaporization assembly 13 extending out of the liquid storage cavity 1101 through the plugging member 113 is located in the housing 111, so that the vaporization assembly 13 is not easy to bend. In another example, compared with the end face of the first end 1111 of the housing 111, the side surface of the plugging member 113 facing toward the outside of the liquid storage cavity 1101 is further away from the second end 1113 of the housing 111. The structure of the vaporization assembly 13 extending out of the liquid storage cavity 1101 through the plugging member 113 completely extends outside the housing 111, to enable the vaporization assembly 13 to be closer to other structures for interacting with the user, reducing loss caused during flowing of the aerosols.

Refer to FIG. 5 and FIG. 6. In some embodiments, the connection portion 15 is a structure that can connect the vaporization cartridge 10 with other components. In some embodiments, the connection portion 15 and the vaporization assembly 13 are integrally formed, and the connection portion 15 is a threaded structure or a snap structure formed after the second end 1303 of the vaporization assembly 13 deforms. In some other embodiments, the connection portion 15 and the vaporization assembly 13 are separately formed, and the connection portion 15 is sleeved on the second end 1303 of the vaporization assembly 13. The outer wall of the connection portion 15 is provided with a thread or a fastener, to enable the connection portion 15 to be connected to other components. In one example, the connection portion 15 is detachably mounted on the second end 1303 of the vaporization assembly 13. The mounting manner includes, but is not limited to, snap-fit connection, threaded connection, and the like. In another example, the connection portion 15 is non-detachably fixed to the second end 1303 of the vaporization assembly 13. The fixation manner includes, but is not limited to, fixation by welding, fixation by interference-fit, fixation by gluing, and the like.

Specifically, with reference to FIG. 4, in some embodiments, the outer contour dimension of the cross-section of the connection portion 15 is greater than the inner contour dimension of the cross-section of the housing 111. Therefore, the end face of the connection portion 15 close to the first end 1301 of the vaporization assembly 13 abuts against the end face of the second end 1113 of the housing 111, to seal the second end 1113 of the housing 111, so as to prevent overflow of the vaporization medium. In some other embodiments, the outer contour dimension of the cross-section of the connection portion 15 is smaller than or equal to the inner contour dimension of the cross-section of the housing 111. Therefore, the outer wall of the vaporization assembly 13 disposed in the liquid storage cavity 1101 abuts against the inner wall of the housing 111, to seal the second end 1113 of the housing 111.

More specifically, in some embodiments, the vaporization cartridge 10 further includes a seal member. The seal member is roughly a flexible structure with relatively stable physical and chemical properties, and the seal member can seal a gap between the vaporization assembly 13 and the housing 111, to prevent overflow of the vaporization medium. The material of the seal member includes, but is not limited to, rubber, silicone, plastic, and the like.

In some embodiments, the seal member is disposed outside the liquid storage cavity 1101. In an example, the outer contour dimension of the cross-section of the connection portion 15 is greater than the inner contour dimension of the cross-section of the housing 111, and the connection portion 15 is spaced apart from the second end 1113 of the housing 111. The seal member is disposed between the end face of the connection portion 15 close to the first end 1301 of the vaporization assembly 13 and the end face of the second end 1113 of the housing 111, to seal the second end 1113 of the housing 111, so as to prevent overflow of the vaporization medium in the liquid storage cavity 1101. In another example, the outer contour dimension of the cross-section of the connection portion 15 is smaller than or equal to the inner contour dimension of the cross-section of the housing 111. The seal member is sleeved on the connection portion 15, and one side of the seal member abuts against the end face of the second end 1113 of the housing 111.

In some other embodiments, the seal member is disposed inside the liquid storage cavity 1101 and located between the inner wall of the housing 111 and the outer wall of the vaporization assembly 13, to seal a gap between the inner wall of the housing 111 and the outer wall of the vaporization assembly 13, so as to prevent overflow of the vaporization medium. Refer to FIG. 5 and FIG. 6. In some embodiments, the vaporization assembly 13 includes a vent tube 131 and a heating component 133 disposed in the vent tube 131. The vent tube 131 is a structure allowing for entry of the vaporization medium and passage of generated aerosols. The vent tube 131 is roughly a columnar structure with an opening. The cross-sectional shape of the vent tube 131 includes, but is not limited to, a circle, an oval, a triangle, a quadrilateral, a pentagon, a hexagon, and the like. The material of the vent tube 131 includes, but is not limited to, plastic, metal, acrylonitrile-butadiene-styrene copolymer (ABS resin), and the like.

Specifically, in some embodiments, the vent tube 131 includes a first end 13101 and a second end 13103 opposite to each other. The first end 13101 of the vent tube 131 passes through the plugging member 113 through the first end 1111 of the housing 111 and is provided with an opening. The second end 13103 of the vent tube 131 extends out of the housing 111 through the second end 1113 of the housing 111. The connection portion 15 is formed at the second end 13103 of the vent tube 131 and is located outside the housing 111. The vaporization medium in the liquid storage cavity 1101 enters the vent tube 131 and can be vaporized into aerosols in the vent tube 131. The aerosols can flow out of the vaporization cartridge 10 through the opening of the first end 13101 of the vent tube 131. In some embodiments, the second end 13103 of the vent tube 131 is a plugging structure, to enable the vaporization medium to be partially stored in the vent tube 131. In some other embodiments, the second end 13103 of the vent tube 131 is also provided with an opening, and the interior structure of the vent tube 131 can be connected to other components through the second end 13103 of the vent tube 131. For example, the heating component 133 in the vent tube 131 is electrically connected to a power supply assembly through the second end 13103 of the vent tube 131.

More specifically, in some embodiments, the vent tube 131 includes a first tube section 1311 and a second tube section 1313 connected to each other. The first tube section 1311 passes through the plugging member 113. A part of the structure of the second tube section 1313 extends out of the housing 111 through the second end 1113 of the housing 111. The connection portion 15 is formed at the part of the second tube section 1313 extending out of the housing 111. Compared with the second tube section 1313, the first tube section 1311 is closer to the mouthpiece component 30 (shown in FIG. 4). The first end 13101 of the vent tube 131 is located at the end of the first tube section 1311 away from the second tube section 1313, and the second end 13103 of the vent tube 131 is located at the end of the second tube section 1313 away from the first tube section 1311. The connection portion 15 is located at the second tube section 1313 and is located outside the housing 111.

The first tube section 1311 is configured to allow for passage of the aerosols, and the second tube section 1313 is configured to accommodate a structure that generates the aerosols and stores part of the vaporization medium. In some embodiments, the inner contour dimension of the cross-section of the first tube section 1311 is the same as the inner contour dimension of the cross- section of the second tube section 1313, to prevent an impact on the outflow of aerosols due to accumulation of the aerosols at a junction between the first tube section 1311 and the second tube section 1313 after the aerosols are condensed. In some other embodiments, the inner contour dimension of the cross-section of the first tube section 1311 is smaller than the inner contour dimension of the cross-section of the second tube section 1313, so that the concentration of the generated aerosols is higher, and the taste of the aerosols is better.

More specifically, in some embodiments, the side wall of the second tube section 1313 located in the liquid storage cavity 1101 is provided with a through hole 1315 communicated with the liquid storage cavity 1101. The quantity of the through hole 1315 may be more than one. In some embodiments, a plurality of through holes 1315 are evenly distributed around the second tube section 1313.

Refer to FIG. 5 and FIG. 6. In some embodiments, the heating component 133 is configured to heat a vaporization medium that is in contact with the heating component 133 and that is in the liquid storage cavity 1101 to form aerosols. The heating component 133 is mounted in the second tube section 1313 and corresponds to the through hole 1315. Therefore, the vaporization medium flowing into the second tube section 1313 through the through hole 1315 can be in contact with the heating component 133, the heating component 133 can heat the vaporization medium to cause the vaporization medium to disperse into fine particles, and the generated particles are mixed with air to form aerosols. The generated aerosols enter the first tube section 1311 through the second tube section 1313, and flow out of the vaporization cartridge 10 through the opening of the first tube section 1311.

Further, in some embodiments, the heating component 133 includes an absorption member 1331 and a heating element 1333. The heating element 1333 is roughly a cylindrical structure, and the heating element 1333 is accommodated in the second tube section 1313. The absorption member 1331 is sleeved on the heating element 1333 and is located between the outer wall of the heating element 1333 and the inner wall of the second tube section 1313. The material of the absorption member 1331 includes, but is not limited to, cotton, polyester fibers, melamine foam, and the like. The vaporization medium can be in contact with the absorption member 1331 through the through hole 1315, and the absorption member 1331 can absorb the vaporization medium and make the vaporization medium be in contact with the heating element 1333.

Still further, in some embodiments, the heating component 133 may further include a ceramic core 1335. The ceramic core 1335 is roughly a cylindrical structure with two open ends, and the heating element 1333 is disposed in the ceramic core 1335. In some embodiments, the electrode of the heating element 1333 extends from an opening at any end of the ceramic core 1335 and is electrically connected to other components. In some other embodiments, a part of the structure of the heating element 1333 passes through the side wall of the ceramic core 1335 and is electrically connected to other components. The absorption member 1331 is sleeved outside the ceramic core 1335. The ceramic core 1335 can support the absorption member 1331 and assist the absorption member 1331 to store part of the vaporization medium.

Furthermore, in some embodiments, the heating element 1333 is a structure capable of generating thermal energy or capable of transferring thermal energy to other parts. The heating element 1333 can heat the vaporization medium in the absorption member 1331 to produce aerosols. The heating element 1333 can directly convert other forms of energy such as electrical energy, chemical energy, and solar energy into thermal energy, and conduct the thermal energy by thermal transfer to other parts that need to be heated. For example, the heating element 1333 is a heating resistor, which can convert electrical energy into thermal energy after being energized. The material of heating element 1333 includes, but is not limited to, ceramic, pure metal, an alloy, and the like. In operating, the heating element 1333 heats the absorption member 1331 to heat up the absorption member 1331. In this case, the vaporization medium can disperse into fine particles, which are mixed with air to form aerosols.

Refer to FIG. 5 and FIG. 6. In some embodiments, the heating element 1333 is provided with two electrodes spaced apart from each other, and the polarities of the two electrodes are opposite. The heating element 1333 can be separately connected to a power supply or a power supply assembly through the two electrodes and heat the vaporization medium absorbed by the absorption member 1331.

Specifically, the connection portion 15 is provided with a first conductive member 151. In some embodiments, the first conductive member 151 and the connection portion 15 are integrally formed. In other words, the first conductive member 151 is a part of the connection portion 15. In some embodiments, the first conductive member 151 and the connection portion 15 are separately formed. The first conductive member 151 is mounted on the connection portion 15 and is located inside the connection portion 15. The material of the first conductive member 151 includes, but is not limited to, metal, conductive plastic, conductive rubber, and the like.

More specifically, the vaporization cartridge 10 further includes a second conductive member 153. The second conductive member 153 is disposed in the connection portion 15 and spaced apart from the inner wall of the connection portion 15, to enable the second conductive member 153 to be electrically insulated from the first conductive member 151, thereby preventing damage to the heating element 1333 caused by a short circuit formed by an electrical connection between the two electrodes. The material of the second conductive member 153 includes, but is not limited to, metal, conductive plastic, conductive rubber, and the like. One of the two electrodes is electrically connected to the first conductive member 151, and the other is electrically connected to the second conductive member 153.

More specifically, the two electrodes are a first electrode 13331 and a second electrode 13333, respectively, and the first electrode 13331 and the second electrode 13333 are spaced apart from each other. The first electrode 13331 is electrically connected to the first conductive member 151, and the second electrode 13333 is electrically connected to the second conductive member 153.

Refer to FIG. 5 and FIG. 6. In some embodiments, the vaporization cartridge 10 further includes a first insulator 17. The first insulator 17 is sleeved on the second conductive member 153 and is located between the first conductive member 151 and the second conductive member 153, and the first insulator 17 is configured for electrical insulation of the first conductive member 151 from the second conductive member 153. The material of the first insulator 17 includes, but is not limited to, plastic, rubber, ceramic, and the like.

Specifically, the first insulator 17 includes an inner wall and an outer wall facing away from each other. The inner wall of the connection portion 15 corresponds to the outer wall of the first insulator 17, and the first conductive member 151 is disposed between the inner wall of the connection portion 15 and the outer wall of the first insulator 17. In some embodiments, the first electrode 13331 is disposed between the inner wall of the connection portion 15 and the first insulator 17. In this case, the inner wall of the connection portion 15 is electrically conductive. In some other embodiments, the first electrode 13331 is disposed between the first conductive member 151 and the outer wall of the first insulator 17. The outer wall of the second conductive member 153 corresponds to the inner wall of the first insulator 17, and the second electrode 13333 is located between the outer wall of the second conductive member 153 and the inner wall of the first insulator 17, to enable the second electrode 13333 to abut against the second conductive member 153 to achieve an electrical connection.

Refer to FIG. 1 and FIG. 2. In some embodiments, the mouthpiece component 30 is a structure allowing for passage of aerosols and capable of interaction with a user. The mouthpiece component 30 is roughly a cylindrical structure with two open ends, and the mouthpiece component 30 includes a first end 31 and a second end 33 opposite to each other. Compared with the first end 31 of the mouthpiece component 30, the second end 33 of the mouthpiece component 30 is closer to the first end 1111 of the housing 111. In some embodiments, the outer contour dimension of the cross-section of the mouthpiece component 30 gradually decreases in the direction from the second end 33 of the mouthpiece component 30 to the first end 31 of the mouthpiece component 30, to facilitate vaping by a user. In some other embodiments, the outer contour dimension of the cross-section of the mouthpiece component 30 is approximately the same in the direction from the second end 33 of the mouthpiece component 30 to the first end 31 of the mouthpiece component 30. In still some other embodiments, the outer contour dimension of the cross-section of the mouthpiece component 30 first decreases and then increases in the direction from the second end 33 of the mouthpiece component 30 to the first end 31 of the mouthpiece component 30. In this case, the appearance of the mouthpiece is ergonomically designed, to increase convenience in use while preventing excessive aerosol overflow. In one example, the outer contour dimension of the cross-section of the first end 31 of the mouthpiece component 30 is always smaller than the outer contour dimension of the cross-section of the second end 33 of the mouthpiece component 30. In another example, the outer contour dimension of the cross-section of the first end 31 of the mouthpiece component 30 is approximately the same as the outer contour dimension of the cross-section of the second end 33 of the mouthpiece component 30.

Further, with reference to FIG. 5, in some embodiments, the mouthpiece component 30 is provided with an air passage 301. The air passage 301 is a cavity that runs through the mouthpiece component 30 and is communicated with the outside. The cross-sectional shape of the air passage 301 includes, but is not limited to, a circle, an oval, a triangle, a quadrilateral, a pentagon, a hexagon, and the like. The air passage 301 includes a first end and a second end opposite to each other. The first end of the air passage 301 is located at the first end 31 of the mouthpiece component 30 and is communicated with the outside, and the second end of the air passage 301 is located inside the mouthpiece component 30. The vent tube 131 of the vaporization cartridge 10 can correspond to the second end of the air passage 301, to enable the aerosols generated in the vaporization cartridge 10 to enter the air passage 301 through the vent tube 131. In a case that the user inhales the aerosols from the mouthpiece component 30, the aerosols can flow from the second end of the air passage 301 to the first end of the air passage 301 for the user to inhale. In some embodiments, at least part of the vent tube 131 extends into the air passage 301 through the second end of the air passage 301, to enable the air passage 301 to be sealed from the vent tube 131, so as to prevent aerosol overflow through a junction between the vent tube 131 and the air passage 301. In some other embodiments, the inner diameter of the vent tube 131 is approximately the same as the inner diameter of the air passage 301. Therefore, in a case that the end of the vent tube 131 abuts against the second end of the air passage 301, the end of the vent tube 131 can be in close contact with the second end of the air passage 301, so that the vent tube 131 is seamlessly communicated with the air passage 301, to enable aerosols to enter the air passage 301 directly through the vent tube 131.

Refer to FIG. 2 and FIG. 3. In some embodiments, the mouthpiece component 30 may further be provided with an accommodating cavity 303 connected to and communicated with the air passage 301. Compared with the position where the air passage 301 is provided, the position where the accommodating cavity 303 is provided is closer to the vaporization cartridge 10 and the accommodating cavity 303 runs through the second end 33 of the mouthpiece component 30. The second end of the air passage 301 is communicated with the accommodating cavity 303, and at least part of the vaporization cartridge 10 extends into the air passage 301, to enable the aerosols generated in the vaporization cartridge 10 to flow into the air passage 301.

Refer to FIG. 2 and FIG. 3. In some embodiments, the vaporizer 100 further includes a connector 50. The material of the connector 50 includes, but is not limited to, metal, plastic, ceramic, and the like. The inner wall of the connector 50 is fitted to the connection portion 15 of the vaporization cartridge 10 (shown in FIG. 4), to enable the vaporization cartridge 10 to be mounted on the connector 50. For example, the outer wall of the connection portion 15 of the vaporization cartridge 10 is provided with a thread, and the inner wall of the connector 50 is provided with a thread corresponding to the outer wall of the connection portion 15 of the vaporization cartridge 10, to enable the vaporization cartridge 10 to be threadedly connected to the connector 50. The outer wall of the connector 50 is fitted to the inner wall of the second end 33 of the mouthpiece component 30, to enable the connector 50 to be mounted in the mouthpiece component 30. In a case that the vaporization cartridge 10 has been mounted to the connector 50, the vaporization cartridge 10 can be mounted in the mouthpiece component 30 through the connector 50.

Refer to FIG. 2 and FIG. 3. In some embodiments, the vaporizer 100 further includes a third conductive member 70 and a second insulator 90. The third conductive member 70 is configured to transfer electrical energy provided by the power supply or the power supply assembly to the heating element 1333 (shown in FIG. 5). The third conductive member 70 is disposed in the connector 50, and the second conductive member 153 (shown in FIG. 6) of the vaporization cartridge 10 is electrically connected to the third conductive member 70. The second insulator 90 is configured for electrical insulation of the third conductive member 70 from the connector 50. The second insulator 90 is sleeved on the third conductive member 70, the inner wall of the second insulator 90 abuts against the outer wall of the third conductive member 70, and the outer wall of the second insulator 90 abuts against the inner wall of the connector 50, so that there is a gap between the third conductive member 70 and the connector 50. The material of the second insulator 90 includes, but is not limited to, plastic, rubber, ceramic, and the like. In some other embodiments, the second conductive member 153 and the third conductive member 70 may be a same conductive member.

Refer to FIG. 7. In some embodiments, the aerosol generation device 1000 in the embodiments of this application includes the vaporizer 100 of any one of the foregoing embodiments.

In summary, in the aerosol generation device 1000 of this application, after the vaporization medium in the vaporization cartridge 10 is used out, the user only needs to replace the vaporization cartridge 10 with a new vaporization cartridge, and other parts of the aerosol generation device 1000 can continue to be used. Therefore, the user can easily add the vaporization medium into the aerosol generation device 1000 by replacing the vaporization cartridge 10.
