[0016] The number of liquid inlet channels is designed according to actual needs, giving the cartridge structure two structural forms: The first method involves a liquid inlet channel on the heating element. The heating element is movably installed within the air duct along a first direction. The e-liquid (oil) in each oil reservoir can flow into the heating element through this liquid inlet channel. When the heating element operates, it atomizes the e-liquid (oil), and the resulting vapor is delivered through the air duct for the user to inhale. A drive component is connected to the heating element, providing power to move the heating element within the air duct. This allows the liquid inlet channel on the heating element to contact different locations within the air duct of the liquid reservoir, ensuring that the liquid inlet channel is either open or blocked from any oil reservoir. This configuration... When using the cartridge structure, the drive component moves the heating element up or down, so that the liquid inlet channel on the heating element comes into contact with the e-liquid (oil) in either oil tank. At this time, the e-liquid (oil) can enter the interior of the heating element through the liquid inlet channel, and the heating element works to atomize the e-liquid (oil). When the cartridge structure is not used, the drive component moves the heating element down or up, so that the liquid inlet channel on the heating element does not come into contact with the e-liquid (oil) in either oil tank. At this time, the e-liquid (oil) cannot enter the interior of the heating element through the liquid inlet channel. This avoids the risk of leakage (oil) and avoids a bad experience for the user.

[0017] The second method involves having at least two liquid inlet channels on the heating element. The heating element is movably installed within the air duct along a first direction. E-liquid (oil) in each oil reservoir can flow into the heating element through one inlet channel. When the heating element operates, it atomizes the e-liquid (oil), and the resulting vapor is delivered through the air duct for the user to inhale. A drive component is connected to the heating element, providing power to move the heating element within the air duct. This allows the liquid inlet channels on the heating element to contact different locations within the air duct of the liquid reservoir, ensuring that each liquid inlet channel is either open or blocked from each oil reservoir. This configuration... When using the cartridge structure, the drive assembly moves the heating element up or down, ensuring that each liquid inlet channel on the heating element contacts the e-liquid (or e-liquid) in the e-liquid tank. In this case, the e-liquid (or e-liquid) can enter the heating element through the inlet channels, and the heating element then atomizes the e-liquid (or e-liquid). When the cartridge structure is not used, the drive assembly moves the heating element down or up, ensuring that each liquid inlet channel on the heating element does not contact the e-liquid (or e-liquid) in the e-liquid tank. In this case, the e-liquid (or e-liquid) cannot enter the heating element through the inlet channels. This avoids the risk of leakage and prevents a negative user experience.

[0024] This utility model embodiment provides a cigarette cartridge structure, referring to... Figure 1 , Figure 2 , Figure 3 and Figure 5 The cartridge structure includes a liquid storage assembly 1, a heating assembly 2, and a driving assembly 3. The liquid storage assembly 1 has at least two oil tanks 4 arranged at intervals along a first direction, and an air passage 5 penetrating the at least two oil tanks 4 along the first direction. The heating assembly 2 is movably installed in the air passage 5 along the first direction. The heating assembly 2 has a liquid inlet channel 6. The driving assembly 3 is connected to the heating assembly 2 and is used to drive the heating assembly 2 to move within the air passage 5, so that the liquid inlet channel 6 is either unobstructed or blocked from any of the oil tanks 4. Alternatively, the heating assembly 2 has at least two liquid inlet channels 6 arranged at intervals along the first direction. The driving assembly 3 is connected to the heating assembly 2 and is used to drive the heating assembly 2 to move within the air passage 5, so that each liquid inlet channel 6 is either unobstructed or blocked from each of the oil tanks 4.

[0025] The first direction is the vertical direction of the liquid storage component 1, which is also the vertical direction of the cartridge structure.

[0026] As an example, the cartridge structure applied in an electronic cigarette specifically includes a liquid storage component 1, a heating component 2, and a driving component 3; the driving component 3 can drive the heating component 2 to move. The liquid storage component 1 has at least two oil tanks 4 arranged at intervals along a first direction, and an air passage 5 passing through the at least two oil tanks 4 along the first direction. The oil tanks 4 store e-liquid (oil). The at least two oil tanks 4 can store atomized liquid of the same flavor, increasing the capacity of the cartridge structure and extending its usage time; they can also store atomized liquids of different flavors to meet users' needs for increased flavor, cooling sensation, nicotine, or other preferences, increasing the diversity of flavors in the cartridge structure, increasing usage choices, and expanding the application range of the cartridge structure.

[0027] The number of liquid inlet channels 6 is designed according to actual needs, so that the cartridge structure has two structural forms: The first method involves providing a liquid inlet channel 6 on the heating element 2. The heating element 2 is movably installed within the air passage 5 along a first direction. The e-liquid (oil) in each oil tank 4 can flow into the heating element 2 through the liquid inlet channel 6. When the heating element 2 operates, it atomizes the e-liquid (oil), and the resulting vapor is delivered through the air passage 5 for the user to inhale. A drive component 3 is connected to the heating element 2, providing power to move the heating element 2 within the air passage 5. This allows the liquid inlet channel 6 on the heating element 2 to contact different positions within the air passage 5 of the liquid storage component 1, ensuring that the liquid inlet channel 6 is either open or blocked from any oil tank 4. The configuration is as follows: When the cartridge structure is used, the drive component 3 drives the heating component 2 to move up or down, so that the liquid inlet channel 6 on the heating component 2 comes into contact with the e-liquid (oil) in any of the oil tanks 4. At this time, the e-liquid (oil) can enter the interior of the heating component 2 through the liquid inlet channel 6, and the heating component 2 works to atomize the e-liquid (oil). When the cartridge structure is not used, the drive component 3 drives the heating component 2 to move down or up, so that the liquid inlet channel 6 on the heating component 2 does not come into contact with the e-liquid (oil) in any of the oil tanks 4. At this time, the e-liquid (oil) cannot enter the interior of the heating component 2 through the liquid inlet channel 6. This avoids the risk of leakage (oil) and avoids a bad experience for the user.

[0028] The second method involves providing at least two liquid inlet channels 6 on the heating element 2. The heating element 2 is movably installed within the air duct 5 along a first direction. E-liquid (oil) in each oil tank 4 can flow into the heating element 2 through one liquid inlet channel 6. When the heating element 2 operates, it atomizes the e-liquid (oil), and the resulting vapor is delivered through the air duct 5 for the user to inhale. A drive component 3 is connected to the heating element 2, providing power to move the heating element 2 within the air duct 5. This allows the liquid inlet channels 6 on the heating element 2 to contact different positions within the air duct 5 of the liquid storage component 1, ensuring that each liquid inlet channel 6 is either open or blocked from an oil tank 4. When the cartridge structure is in use, the drive assembly 3 drives the heating assembly 2 to move up or down, so that each liquid inlet channel 6 on the heating assembly 2 comes into contact with the e-liquid (oil) in the oil tank 4. At this time, the e-liquid (oil) can enter the interior of the heating assembly 2 through the liquid inlet channel 6, and the heating assembly 2 works to atomize the e-liquid (oil). When the cartridge structure is not in use, the drive assembly 3 drives the heating assembly 2 to move down or up, so that each liquid inlet channel 6 on the heating assembly 2 does not come into contact with the e-liquid (oil) in the oil tank 4. At this time, the e-liquid (oil) cannot enter the interior of the heating assembly 2 through the liquid inlet channel 6. This avoids the risk of leakage (oil) and avoids a bad experience for the user.

[0029] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 3 The liquid storage assembly 1 includes a first liquid storage shell 11, a second liquid storage shell 12, and a liquid storage base 13; the first end of the first liquid storage shell 11 is provided with a mouthpiece 14, the first end of the second liquid storage shell 12 is installed at the second end of the first liquid storage shell 11, and the two cooperate to form an oil tank 4; the liquid storage base 13 is installed at the second end of the second liquid storage shell 12, and the two cooperate to form another oil tank 4; each oil tank 4 is provided with a liquid storage cotton; the first end of the first liquid storage shell 11 is provided with a first through groove, the first end of the second liquid storage shell 12 is provided with a second through groove, and the liquid storage base 13 is provided with a third through groove, and the first through groove, the second through groove, and the third through groove cooperate to form an air passage 5.

[0030] As an example, the liquid storage assembly 1 includes a first liquid storage shell 11, a second liquid storage shell 12, and a liquid storage base 13. The first liquid storage shell 11 is an open-type shell structure, and a mouthpiece 14 is provided at the first end of the first liquid storage shell 11. The mouthpiece 14 is connected to the air passage 5 of the cartridge structure, providing convenience for the user to inhale smoke. The liquid storage assembly 1 also includes a filter ring, such as an O-ring, made of silicone material, which can filter the passing smoke. The second liquid storage shell 12 is also an open-type shell structure. The first end of the second liquid storage shell 12 is installed at the second end of the first liquid storage shell 11, and the two cooperate to form an oil reservoir 4. Specifically, a protrusion or a groove is provided at the first end of the second liquid storage shell 12, and a groove or a protrusion is provided at the second end of the first liquid storage shell 11. The groove and the protrusion engage, facilitating the assembly of the second liquid storage shell 12 and the first liquid storage shell 11 together. A liquid storage base 13 is installed at the second end of the second liquid storage shell 12, and the two cooperate to form another oil tank 4. Specifically, a protrusion or groove is provided on the second end of the second liquid storage shell 12, and a groove or protrusion is provided on the liquid storage base 13. The groove and the protrusion engage to facilitate the assembly of the second liquid storage shell 12 and the liquid storage base 13 together. Each oil tank 4 is provided with a liquid storage cotton, which is used to store e-liquid (oil). The first liquid storage shell 11 has a first through groove at its first end, the second liquid storage shell 12 has a second through groove at its first end, and the liquid storage base 13 has a third through groove. The first through groove, the second through groove, and the third through groove cooperate to form an air passage 5. With this configuration, when the cartridge structure is used, the driving component 3 drives the heating component 2 to move up or down, so that the liquid inlet channel 6 on the heating component 2 connects with the liquid storage cotton. At this time, the e-liquid (oil) in the liquid storage cotton can enter the interior of the heating component 2 through the liquid inlet channel 6, and the heating component 2 works to atomize the e-liquid (oil). When the cartridge structure is not used, the driving component 3 drives the heating component 2 to move down or up, so that the liquid inlet channel 6 on the heating component 2 does not connect with the liquid storage cotton. At this time, the e-liquid (oil) in the liquid storage cotton cannot enter the interior of the heating component 2 through the liquid inlet channel 6. This avoids the risk of leakage (oil) and avoids a bad experience for the user.

[0031] In one embodiment, reference is made to Figure 2 The liquid storage assembly 1 also includes a first seal 15, a second seal 16 and a third seal 17; the first seal 15 is disposed in the first through groove and is slidably fitted with the heating assembly 2; the second seal 16 is disposed in the second through groove and is slidably fitted with the heating assembly 2; the third seal 17 is disposed in the third through groove and is slidably fitted with the heating assembly 2.

[0032] As an example, the liquid storage assembly 1 also includes a first seal 15, a second seal 16, and a third seal 17. During installation, the first seal 15 is placed in the first through groove and slidably fitted with the heating assembly 2; the second seal 16 is placed in the second through groove and slidably fitted with the heating assembly 2; the third seal 17 is placed in the third through groove and slidably fitted with the heating assembly 2. This arrangement prevents the e-liquid (oil) in the oil tank 4 from leaking from the first through groove, the second through groove, and the third through groove when the heating assembly 2 moves, thereby improving the sealing performance of the e-liquid cartridge structure.

[0033] In one embodiment, reference is made to Figure 2 and Figure 5 The heating element 2 includes a heating tube 21 and a heating core 22. The heating tube 21 is movably installed in the air passage 5 along the first direction. One end of the heating tube 21 extends outside the air passage 5 and is connected to the driving element 3. The heating core 22 is installed inside the heating tube 21. The heating tube 21 is provided with one liquid inlet channel 6 or at least two liquid inlet channels 6, and each liquid inlet channel 6 corresponds to the heating core 22.

[0034] As an example, the heating component 2 includes a heating tube 21 and a heating core 22; the heating tube 21 is movably installed in the air passage 5 along a first direction, one end of the heating tube 21 extends outside the air passage 5 and is connected to the driving component 3, and the heating core 22 is installed in the heating tube 21; the heating tube 21 is provided with a liquid inlet channel 6 or at least two liquid inlet channels 6, each liquid inlet channel 6 corresponding to the heating core 22.

[0035] The heating element 2 includes a heating tube 21 and a heating core 22. During installation, the heating tube 21 is movably installed in the air passage 5 along a first direction. One end of the heating tube 21 extends outside the air passage 5 and is connected to the drive component 3. Specifically, the heating tube 21 is a long tube, and one end of the heating tube 21 is connected to the connecting part of the drive component 3. The drive component 3 can drive the heating tube 21 to move within the air passage 5. The heating core 22 is installed inside the heating tube 21. The heating tube 21 is provided with one or at least two liquid inlet channels 6, each corresponding to the heating core 22. Specifically, the heating tube 21 is provided with one or multiple sets of through holes arranged at intervals along the first direction. Each set of through holes includes a section along the heating tube 21. Multiple through holes are arranged at intervals along the circumference of the heating element. This arrangement ensures that when the driving component 3 moves the heating element 21 up or down, the liquid inlet channel 6 on the heating element 21 connects with the liquid storage cotton. At this time, the e-liquid (oil) in the liquid storage cotton can enter the interior of the heating element 21 through the liquid inlet channel 6 and contact the heating core 22, causing the heating core 22 to work and atomize the e-liquid (oil). When the driving component 3 moves the heating element 21 down or up, the liquid inlet channel 6 on the heating element 21 does not connect with the liquid storage cotton. At this time, the e-liquid (oil) in the liquid storage cotton cannot enter the interior of the heating element 21 through the liquid inlet channel 6. This avoids the risk of leakage (oil) and prevents a poor user experience.

[0036] In one embodiment, reference is made to Figure 2 , Figure 4 and Figure 5 The drive assembly 3 includes a drive bracket 31, a slider 32, a motor 33, and a drive member 34. The slider 32 is movably mounted on the drive bracket 31 along a first direction, and one end of the slider 32 is connected to the heating element 2. The motor 33 is mounted on the drive bracket 31, and the output end of the motor 33 is connected to one end of the drive member 34. The drive member 34 is connected to the slider 32, and under the action of the motor 33, the drive member 34 drives the slider 32 to move. Alternatively, the drive assembly 3 includes a drive bracket 31, a slider 32, a cylinder, and a telescopic column. The slider 32 is movably mounted on the drive bracket 31 along a first direction, and one end of the slider 32 is connected to the heating element 2. The cylinder is mounted on the drive bracket 31, one end of the telescopic column is connected to the cylinder, and the other end of the telescopic column is connected to the slider 32.

[0037] As an example, two structural forms of driver component 3 are introduced: The first type is a motor-driven assembly. The drive assembly 3 includes a drive bracket 31, a slider 32, a motor 33, and a drive element 34. The drive bracket 31 serves as a reference. During installation, the slider 32 is movably mounted on the drive bracket 31 along a first direction. Specifically, the drive bracket 31 has a sliding groove arranged along the first direction, and the slider 32 is slidably mounted in the sliding groove. One end of the slider 32 is connected to the heating element 2, which can drive the heating element 2 to move along the first direction. The motor 33 is mounted on the drive bracket 31, and the output end of the motor 33 is connected to one end of the drive element 34. The drive element 34 is connected to the slider 32. Specifically, the other end of the drive element 34 has a threaded section, and the slider 32 has a threaded groove, with the threaded section threaded into the threaded groove. With this configuration, when the motor 33 rotates forward or reverse, it can drive the slider 32 to move along the first direction via the drive element 34, thereby driving the heating element 2 to move along the first direction within the air passage 5. When the heating element 2 is moved upward or downward, the liquid inlet channel on the heating tube 21 of the heating element 2... 6. When the heating element 2 is connected to the liquid storage cotton, the e-liquid (oil) in the liquid storage cotton can enter the heating tube 21 through the liquid inlet channel 6 and contact the heating core 22. The heating core 22 then works to atomize the e-liquid (oil). When the heating element 2 is moved down or up, the liquid inlet channel 6 on the heating tube 21 of the heating element 2 is not connected to the liquid storage cotton. At this time, the e-liquid (oil) in the liquid storage cotton cannot enter the heating tube 21 through the liquid inlet channel 6, and atomization cannot be achieved. This avoids the risk of leakage (oil) and prevents a bad user experience. The motor 33 can be a stepper motor, the drive component 34 is a threaded rod, and the other end of the sliding component 32 is threadedly connected to the drive component 34. The stepper motor has high precision, and its forward and reverse rotation can drive the threaded rod to rotate forward and reverse, thereby driving the sliding component 32 to move along the axial direction of the threaded rod, thus realizing the up and down displacement of the heating element 2.

[0038] The second type is a cylinder-type drive assembly. The drive assembly 3 includes a drive bracket 31, a sliding member 32, a cylinder, and a telescopic column. The sliding member 32 is movably mounted on the drive bracket 31 along a first direction, and one end of the sliding member 32 is connected to the heating element 2. The cylinder is mounted on the drive bracket 31, one end of the telescopic column is connected to the cylinder, and the other end of the telescopic column is connected to the sliding member 32. With this configuration, the cylinder can drive the telescopic column to move along the first direction, thereby driving the sliding member 32 to move, thus realizing the movement of the heating element 2, and also achieving the above-mentioned function.

[0039] In one embodiment, reference is made to Figure 2 and Figure 4 The drive assembly 3 also includes a guide member 35; a guide sleeve 36 is provided on the drive bracket 31; one end of the guide member 35 is connected to the sliding member 32, and the other end of the guide member 35 passes through the guide sleeve 36.

[0040] As an example, the drive assembly 3 also includes a guide 35; a guide sleeve 36 is provided on the drive bracket 31. During installation, one end of the guide 35 is connected to the slider 32, and the other end of the guide 35 is inserted into the guide sleeve 36. With this configuration, the guide 35 can provide guidance and limit for the movement of the slider 32, avoid misalignment of the slider 32, and ensure smooth movement of the heating assembly 2.

[0041] In one embodiment, reference is made to Figure 2 and Figure 4 The sliding member 32 includes a sliding seat 321 and a sliding shell 322. The sliding seat 321 is connected to the driving member 34, and the sliding shell 322 is connected to the heating component 2. The sliding seat 321 is installed at the open end of the sliding shell 322, and the two cooperate to form an air regulating chamber 7. An air regulating component 8 is provided on the driving bracket 31. The sliding shell 322 is provided with a through hole connecting the air regulating chamber 7 and the air passage 5, and an air exchange hole connecting the air regulating chamber 7 and the outside. The guide member 35 is provided with an airflow channel connecting the air regulating chamber 7 and the air regulating component 8.

[0042] As an example, the sliding element 32 includes a sliding seat 321 and a sliding shell 322. During installation, the sliding seat 321 is connected to the driving element 34, and the sliding shell 322 is connected to the heating element 2. The sliding seat 321 is installed at the open end of the sliding shell 322. With this configuration, the driving element 34 drives the sliding seat 321 to move, which in turn drives the heating element 2 to move through the sliding shell 322, so that the liquid inlet channel 6 on the heating tube 21 of the heating element 2 can be connected to or not connected to the liquid storage cotton. The air regulating chamber 7 formed by the sliding seat 321 and the sliding shell 322 serves as an independent airflow buffer chamber, which can stabilize airflow pressure fluctuations. For example, when the user draws air quickly, the air regulating chamber 7 absorbs the instantaneous airflow impact through volume changes, preventing leakage or dry burning caused by a sudden drop in pressure in the airway 5. The air regulating element 8 (such as a rotary valve or a slider valve) achieves multi-stage adjustment of airflow by changing the communication area between the air regulating chamber 7 and the airway 5. The vent on the sliding housing 322 connects the air regulating chamber 7 to the outside, forming an auxiliary airflow path to prevent liquid from the oil tank 4 from being drawn into the air passage 5 due to excessive negative pressure. When the negative pressure in the air passage 5 increases, the vent automatically replenishes outside air to prevent the air flow rate in the air regulating chamber 7 from decreasing due to the vacuum effect. The airflow channel in the guide 35 precisely aligns the air regulating chamber 7 with the air regulating component 8, reducing airflow bends and turbulence.

[0043] This utility model embodiment provides an electronic cigarette, see reference. Figure 1 , Figure 2 and Figure 3 It includes a power supply structure 9 and a cartridge structure; the power supply structure 9 is installed on the liquid storage component 1 and the drive component 3, and is connected to the heating component 2 and the drive component 3.

[0044] As an example, an electronic cigarette includes a power supply structure 9 and a cartridge structure. During installation, the power supply structure 9 is mounted on the liquid storage component 1 and the drive component 3, and connected to the heating component 2 and the drive component 3. With this configuration, the second liquid storage shell 12 of the liquid storage component 1 and the drive bracket 31 of the drive component 3 can provide mounting support for the power supply structure 9. The heating component 2 and the motor 33 can obtain power from the power supply structure 9 to operate. The position of the heating component 2 can be adjusted by the motor 33. When the user inhales, the liquid inlet channel 6 on the heating component 2 and the oil tank 4 of the liquid storage component 1 are kept unobstructed, providing convenience for the user to use the cartridge structure. When the user does not inhale, the liquid inlet channel 6 on the heating component 2 and the oil tank 4 of the liquid storage component 1 are blocked. At this time, the e-liquid (oil) cannot enter the interior of the heating component 2 through the liquid inlet channel 6. This avoids the risk of leakage (oil) and prevents a bad experience for the user.

[0045] In one embodiment, reference is made to Figure 2 and Figure 3 The power supply structure 9 includes a power supply bracket 91, a digital tube and PCBA assembly 92, a battery cell 93, and a lens 94. The power supply bracket 91 is mounted on the liquid storage assembly 1 and the drive assembly 3. The digital tube and PCBA assembly 92 and the battery cell 93 are mounted inside the power supply bracket 91 and connected to the heating assembly 2 and the drive assembly 3. The lens 94 is mounted on the power supply bracket 91 and is correspondingly arranged with the digital tube and PCBA assembly 92.

[0046] As an example, the power supply structure 9 includes a power supply bracket 91, a digital display and PCBA assembly 92, a battery cell 93, and a lens 94. The power supply bracket 91 is installed in a dual-component configuration, simultaneously fixed to the second liquid storage shell 12 of the liquid storage assembly 1 and the drive bracket 31 of the drive assembly 3, forming a structurally stable triangular relationship. The digital display and PCBA assembly 92 and the battery cell 93 are installed inside the power supply bracket 91 and connected to the heating assembly 2 and the drive assembly 3. With this configuration, the battery cell 93 provides electrical energy, and the digital display and PCBA assembly 92 can display information such as battery level, number of suctions, and power level in real time. The lens 94 is installed on the power supply bracket 91 and is correspondingly positioned to correspond with the digital display and PCBA assembly 92, providing convenience for users to observe information such as battery level, number of suctions, and power level.

[0047] In one embodiment, reference is made to Figure 1 and Figure 3 The electronic cigarette also includes a protective shell 10, and the power supply structure 9 and the cartridge structure are all embedded in the protective shell 10.

[0048] As an example, the electronic cigarette also includes a protective shell 10, which is a U-shaped cylindrical structure. During installation, both the power supply structure 9 and the cartridge structure are embedded within the protective shell 10. Specifically, the protective shell 10 is fitted onto the second liquid storage shell 12 of the liquid storage assembly 1, providing protection for the cartridge structure and the power supply structure 9. The protective shell 10 is a transparent shell, and one side of the protective shell 10 has an operation groove containing a lens 94, providing convenience for the user to observe information such as battery level, number of puffs, and power level.
