The atomizing core and the oil storage device can be directly separated when not in use, so that the heating core is prevented from being soaked in the tobacco tar for a long time and corroded.

Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an atomization device with a replaceable coil when fully filled with oil. Background Technology

[0002] Currently, existing atomizing devices, in order to make the atomizer coil replaceable, all have a plug-in channel at the bottom of the e-liquid reservoir that communicates with the e-liquid chamber. The atomizer coil is inserted into the e-liquid chamber through the plug-in channel to atomize e-liquid. When there is no e-liquid in the e-liquid chamber, the atomizer coil can be plugged in and out of the e-liquid chamber through the plug-in channel to replace it. However, with this coil replacement structure, if the atomizer coil malfunctions and needs to be replaced while there is e-liquid in the e-liquid chamber, directly pulling the atomizer coil out of the plug-in channel will cause e-liquid to flow out of the plug-in channel, resulting in waste. Furthermore, if the device is not used for a long time after use, and there is e-liquid in the e-liquid chamber, the atomizer coil cannot be directly pulled out and separated from the e-liquid chamber. E-liquid in the e-liquid chamber will enter the heating element through the e-liquid inlet and be immersed in it for a long time, which will accelerate the corrosion of the heating element and thus affect the lifespan of the heating element and the flavor of the e-liquid. Utility Model Content

[0003] The purpose of this application is to provide an atomizing device with a replaceable coil when the coil is full of e-liquid, which solves the problems in the prior art where the coil cannot be directly removed and replaced when it malfunctions while the e-liquid is in the e-liquid chamber, and the coil cannot be directly pulled out and separated from the e-liquid chamber after being used for a long time without being used. Furthermore, the heating coil will corrode faster due to long-term immersion in e-liquid, thus affecting the service life of the heating coil and the flavor of the e-liquid.

[0004] The technical solution adopted by this application to solve the above-mentioned technical problems is: a fully filled and replaceable coil atomizing device, including an oil reservoir and an atomizing coil. The oil reservoir has an oil chamber for storing e-liquid and an insertion / removal channel communicating with the oil chamber. An air tube is provided in the oil chamber, and a movable member with its upper end extending into the air tube and its lower end blocking the insertion / removal channel is provided. The air tube has a step corresponding to the movable member and a spring abutting against the movable member. The atomizing coil has a heating element and an oil inlet corresponding to the heating element. When the atomizing coil is inserted into the insertion / removal channel and the movable member is pushed to abut against the step, the oil inlet can move into the oil chamber. When the atomizing coil is pulled out from the insertion / removal channel, the movable member can be reset under the elastic force of the spring to block the insertion / removal channel.

[0005] In one embodiment, the trachea, the movable component, and the insertion / removal channel are located on the same vertical line from top to bottom.

[0006] In one embodiment, the step is formed by expanding the inner wall of the lower end of the trachea, the upper end of the movable member extends into the lower end of the trachea, and the upper end of the movable member is fitted with a first sealing ring that abuts against the inner wall of the lower end of the trachea.

[0007] In one embodiment, the lower end of the movable component extends into the upper end of the insertion / removal channel, and the lower end of the movable component is fitted with a sealing ring that abuts against the upper end of the insertion / removal channel. The lower end of the movable component blocks the upper end of the insertion / removal channel through the sealing ring. After the atomizing core is inserted into the insertion / removal channel, the top end of the atomizing core abuts against the bottom end of the sealing ring.

[0008] In one embodiment, the oil reservoir includes an oil tank, the air pipe and the movable component are located inside the oil tank, a connector is provided at the upper end of the inner wall of the oil tank, the upper end of the air pipe is sleeved on the connector, the space between the outer wall of the air pipe and the outer wall of the movable component and the inner wall of the oil tank serves as the oil cavity, the top end of the spring abuts against the bottom end of the connector, and the bottom end of the spring abuts against the top end of the movable component.

[0009] In one embodiment, the top of the oil tank is provided with a suction nozzle, the top of the suction nozzle is provided with a smoking channel extending to the bottom of the connector, the air pipe is provided with a smoke exhaust channel corresponding to and communicating with the smoking channel, and the movable part is provided with a receiving channel corresponding to and communicating with the smoke exhaust channel.

[0010] In one embodiment, the oil reservoir further includes a base and a sealing sleeve. The sealing sleeve is fitted onto the outer wall of the base, and the base is inserted into the bottom opening of the oil tank. The sealing sleeve abuts against the inner wall of the oil tank. The insertion / removal channel extends from the bottom of the base to the top of the base. The insertion / removal channel corresponds to the movable member. Under the elastic force of the spring, the lower end of the movable member can extend into the insertion / removal channel and abut against the upper end of the insertion / removal channel through the sealing oil ring, thereby isolating the oil cavity from the insertion / removal channel. The atomizing core has an atomizing channel, and the atomizing core is inserted into the insertion / removal channel. The atomizing channel corresponds to and communicates with the receiving channel.

[0011] In one embodiment, the atomizing core includes an atomizing tube, the atomizing channel is formed inside the atomizing tube, the heating core is disposed inside the atomizing tube, the oil inlet is opened on the outer wall of the atomizing tube, the top end of the atomizing tube abuts against the bottom end of the sealing ring, the bottom end of the atomizing tube is exposed at the bottom end of the base, and the bottom end of the atomizing tube is provided with an air inlet communicating with the atomizing channel.

[0012] In one embodiment, the outer wall of the base is provided with a buckle, and the outer wall of the oil tank is provided with a buckle hole corresponding to the buckle. The base is fixed in the bottom opening of the oil tank by the buckle being engaged with the buckle hole.

[0013] In one embodiment, the upper end of the atomizing tube is fitted with a second sealing ring that abuts against the upper end of the insertion / removal channel, the lower end of the atomizing tube is fitted with a third sealing ring located above the oil inlet hole, and a fourth sealing ring located below the oil inlet hole, and the bottom end of the atomizing tube is provided with a conductive electrode that is electrically connected to the heating element.

[0014] The atomizer with a replaceable coil when fully filled with e-liquid, as described in this application, has the following beneficial effects: In this atomizer, the spring force causes the moving part to move downwards and block the insertion / removal channel when the atomizer coil is inserted or removed from the insertion / removal channel. Therefore, when there is e-liquid in the e-liquid chamber, if the atomizer coil malfunctions, it can be directly removed and replaced from the insertion / removal channel without the e-liquid flowing out and being wasted. Furthermore, if the atomizer coil is not used for an extended period after activation, it can be directly separated from the e-liquid chamber when there is e-liquid present. This prevents the heating element from being soaked in e-liquid for extended periods, thus avoiding accelerated corrosion and impacting the lifespan of the heating element and the flavor of the e-liquid.

It should be noted that, as long as there is no conflict, the various embodiments and features in each embodiment of this application can be combined with each other, and the resulting technical solutions are all within the protection scope of this application.

[0017] It should be noted that the specification of this application contains a large number of technical features distributed across various technical solutions. Listing all possible combinations of technical features (i.e., technical solutions) would make the specification overly lengthy. To avoid this problem, the various technical features claimed in the above-described utility model content, the various technical features claimed in the following embodiments and examples, and the various technical features claimed in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible. For example, in one example, feature A+B+C is claimed, and in another example, feature A+B+D+E is claimed. Features C and D are equivalent technical means that serve the same function, and technically only one needs to be used; they cannot be used simultaneously. Feature E can be technically combined with feature C. Therefore, the solution A+B+C+D should not be considered as having been described because it is technically infeasible, while the solution A+B+C+E should be considered as having been described.

[0018] In this application, the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., are based on the orientation or positional relationship shown in the accompanying drawings and are only for the purpose of describing and understanding the technology of this application, and are not intended to limit the device or component to have a specific orientation or to be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0019] like Figs. 1-6As shown, this application provides an atomizing device with a replaceable coil when fully filled with e-liquid, including an e-liquid reservoir 9 and an atomizing coil 16. The e-liquid reservoir 9 has an e-liquid chamber 101 for storing e-liquid, and an insertion / removal channel 802 communicating with the e-liquid chamber 101. An air tube 2 is provided in the e-liquid chamber 101, and a movable member 5 with its upper end extending into the air tube 2 and its lower end blocking the insertion / removal channel 802 is provided. The air tube 2 has a step 202 corresponding to the movable member 5, and a step that abuts against the movable member 5. The spring 3, the atomizing core 16 has a heating core 13 inside, and the atomizing core 16 has an oil inlet hole 1402 corresponding to the heating core 13. When the atomizing core 16 is inserted into the insertion channel 802 and the movable part 5 is pushed to abut against the step 202, the oil inlet hole 1402 can move into the oil chamber 101. When the atomizing core 16 is pulled out from the insertion channel 802, the movable part 5 can be reset under the elastic force of the spring 3 to block the insertion channel 802. It should be noted that when the atomizing core 16 is inserted or removed from the insertion / removal channel 802 by the elastic force of the spring 3, the movable part 5 will move downward to block the insertion / removal channel 802. Thus, when there is e-liquid in the e-liquid chamber 101, if the atomizing core 16 malfunctions, it can be directly pulled out from the insertion / removal channel 802 for replacement. The e-liquid in the e-liquid chamber 101 will not flow out from the insertion / removal channel 802 and be wasted. After being used for a long time without being used, the atomizing core 16 can be directly separated from the e-liquid chamber 101 when there is e-liquid. The heating core 13 will not be soaked in the e-liquid in the e-liquid in the e-liquid for a long time, which will accelerate corrosion and affect the service life of the heating core 13 and the flavor of the e-liquid.

[0020] In some embodiments, the air tube 2, the movable component 5, and the insertion / removal channel 802 are located on the same vertical line from top to bottom. It should be noted that, based on the positional relationship between the air tube 2, the movable component 5, and the insertion / removal channel 802, when the atomizing core 16 is inserted into the insertion / removal channel 802 and pushes the movable component 5, the movable component 5 will not shift or get stuck, and can easily move to abut against the step 202, thereby allowing the oil inlet 1402 to move completely into the oil chamber 101.

[0021] In some embodiments, the step 202 is formed by expanding the inner wall of the lower end of the air pipe 2, and the upper end of the movable member 5 extends into the lower end of the air pipe 2. A first sealing ring 4 is fitted on the upper end of the movable member 5 to abut against the inner wall of the lower end of the air pipe 2. The step 202 is used to limit the upward movement of the movable member 5, thereby controlling the depth of the atomizing core 16 into the oil cavity 101. The first sealing ring 4 is used to seal the gap between the upper end of the movable member 5 and the inner wall of the lower end of the air pipe 2, preventing e-liquid in the oil cavity 101 from entering the air pipe 2 through the gap between the two and causing oil leakage.

[0022] In some embodiments, the lower end of the movable member 5 extends into the upper end of the insertion / removal channel 802. A sealing ring 6, which abuts against the upper end of the insertion / removal channel 802, is fitted onto the lower end of the movable member 5. The sealing ring 6 blocks the upper end of the insertion / removal channel 802. After the atomizing core 16 is inserted into the insertion / removal channel 802, the top end of the atomizing core 16 abuts against the bottom end of the sealing ring 6. The sealing ring 6 seals the gap between the lower end of the movable member 5 and the upper end of the insertion / removal channel 802, preventing e-liquid in the oil cavity 101 from entering the insertion / removal channel 802 through the gap, thus preventing leakage. The abutment between the top end of the atomizing core 16 and the bottom end of the sealing ring 6 prevents e-liquid in the oil cavity 101 from entering the interior of the atomizing core 16 from the top end during the process of the atomizing core 16 pushing the sliding member into the oil cavity 101, thus preventing leakage.

[0023] In some embodiments, the oil reservoir 9 includes an oil tank 1, an air pipe 2, and a movable component 5 located inside the oil tank 1. A connector 102 is provided at the upper end of the inner wall of the oil tank 1. The upper end of the air pipe 2 is sleeved on the connector 102. The space between the outer wall of the air pipe 2, the outer wall of the movable component 5, and the inner wall of the oil tank 1 serves as an oil cavity 101. The top end of the spring 3 abuts against the bottom end of the connector 102, and the bottom end of the spring 3 abuts against the top end of the movable component 5. The connector 102 is used to connect and position the air pipe 2. When the atomizing core 16 pushes the movable component 5 to move to the upper end inside the air pipe 2, the spring 3 can deform under pressure and generate elastic force. When the atomizing core 16 is pulled out from the insertion / removal channel 802, the lower end of the movable component 5 will be ejected into the upper end of the insertion / removal channel 802 under the elastic force of the spring 3, and the insertion / removal channel 802 will be sealed by the sealing oil ring 6.

[0024] In some embodiments, the top of the oil tank 1 is provided with a suction nozzle 103, and the top of the suction nozzle 103 has a smoke-smoking channel 104 extending to the bottom of the connector 102. A smoke-exhausting channel 201 corresponding to and communicating with the smoke-smoking channel 104 is formed in the air pipe 2, and a receiving channel 501 corresponding to and communicating with the smoke-exhausting channel 201 is formed in the movable part 5. The suction nozzle 103, the connector 102, and the smoke-smoking channel 104 are integrally formed with the oil tank 1 by in-mold injection molding. The suction nozzle 103 is used to hold the smoke in the mouth, the smoke-exhausting channel 201 and the receiving channel 501 are both used to exhaust smoke, and the smoke-smoking channel 104 is used to draw smoke into the mouth.

[0025] In some embodiments, the oil reservoir 9 further includes a base 8 and a sealing sleeve 7. The sealing sleeve 7 is fitted onto the outer wall of the base 8. The base 8 is inserted into the bottom opening of the oil tank 1. The sealing sleeve 7 abuts against the inner wall of the oil tank 1. The insertion / removal channel 802 extends from the bottom end of the base 8 to the top end of the base 8. The insertion / removal channel 802 corresponds to the movable member 5. Under the elastic force of the spring 3, the lower end of the movable member 5 can extend into the insertion / removal channel 802 and abut against the upper end of the insertion / removal channel 802 through the sealing oil ring 6, so that the oil cavity 101 is isolated from the insertion / removal channel 802. The atomizing core 16 has an atomizing channel 1401. The atomizing core 16 is inserted into the insertion / removal channel 802. The atomizing channel 1401 corresponds to and communicates with the receiving channel 501. Among them, the base 8 is used to seal the oil cavity 101, the sealing sleeve 7 is used to seal the gap between the inner wall of the oil tank 1 and the outer wall of the base 8, the insertion channel 802 and the base 8 are also integrally formed by in-mold injection molding, and the atomizing channel 1401 is used to accommodate the heating core 13 and the airflow.

[0026] In some embodiments, the atomizing core 16 includes an atomizing tube 14, an atomizing channel 1401 formed inside the atomizing tube 14, a heating core 13 disposed inside the atomizing tube 14, an oil inlet 1402 formed on the outer wall of the atomizing tube 14, the top end of the atomizing tube 14 abutting against the bottom end of the sealing ring 6, the bottom end of the atomizing tube 14 exposed at the bottom end of the base 8, and an air inlet 1403 communicating with the atomizing channel 1401 at the bottom end of the atomizing tube 14. The atomizing tube 14 is made of stainless steel, which will not be corroded by e-liquid, and will not deform due to the heating core 13. E-liquid in the oil chamber 101 can enter the heating core 13 through the oil inlet 1402 and be heated to produce vapor. The bottom end of the atomizing tube 14 exposed at the bottom end of the base 8 facilitates the removal of the atomizing core 16 from the oil chamber 101 and the insertion / removal channel 802. The air inlet 1403 is used to introduce air into the atomizing channel 1401 to drive the vapor flow.

[0027] In some embodiments, the outer wall of the base 8 is provided with a buckle 801, and the outer wall of the oil tank 1 is provided with a buckle hole 105 corresponding to the buckle 801. The base 8 is fixed in the bottom opening of the oil tank 1 by the buckle 801 being engaged in the buckle hole 105. Wherein, by the buckle 801 being engaged in the buckle hole 105, when the atomizing core 16 is inserted into the insertion / removal channel 802, the base 8 will not move upward, and when the atomizing core 16 is removed from the insertion / removal channel 802, the base 8 will not be pulled out from the bottom opening of the oil tank 1.

[0028] In some embodiments, the upper end of the atomizing tube 14 is fitted with a second sealing ring 10 that abuts against the upper end of the insertion / removal channel 802, the lower end of the atomizing tube 14 is fitted with a third sealing ring 11 located above the oil inlet 1402, and a fourth sealing ring 12 located below the oil inlet 1402, and the bottom end of the atomizing tube 14 is provided with a conductive electrode 15 electrically connected to the heating core 13. It should be noted that when the atomizing tube 14 of the atomizing core 16 pushes the movable member 5 to move towards the upper end of the air tube 2, the upper end of the atomizing tube 14 also moves towards the lower end of the air tube 2. At this time, the second sealing ring 10 can seal the gap between the upper end of the atomizing tube 14 and the inner wall of the lower end of the air tube 2, preventing e-liquid in the oil chamber 101 from entering the gap between them. When the atomizing tube 14 pushes the movable member 5 to abut against the step 202, the oil inlet 1402 is just completely moved into the oil chamber 101. At this time, the third sealing ring 11... The gap between the lower end of the atomizing tube 14 and the inner wall of the lower end of the air tube 2 can be sealed to prevent the e-liquid in the oil chamber 101 from entering the gap between the two. The fourth sealing ring 12 can seal the gap between the lower end of the atomizing tube 14 and the upper end of the plug-in channel 802 to prevent the e-liquid in the oil chamber 101 from entering the plug-in channel 802 and then flowing out, causing oil leakage. The conductive electrode 15 is used to electrically connect the heating core 13. When the atomizing device is electrically connected to the power supply equipment, the heating core 13 is energized through the conductive electrode 15 to make it heat up.

[0029] The following detailed description uses preferred embodiments.

[0030] like Figs. 1-6As shown, the atomizing device of this application includes: an oil reservoir 9 and an atomizing core 16. The oil reservoir 9 includes: an oil tank 1, an air tube 2, a spring 3, a first sealing ring 4, a movable part 5, an oil sealing ring 6, a sealing sleeve 7, and a base 8. The first sealing ring 4 is sleeved on the upper end of the movable part 5, and the upper end of the movable part 5 extends into the lower end of the air tube 2 for connection. The first sealing ring 4 abuts against the inner wall of the lower end of the air tube 2 to seal the gap between the upper end of the movable part 5 and the inner wall of the lower end of the air tube 2. The spring 3 is installed inside the air tube 2. The air tube 2 and the movable part 5 are installed inside the oil tank 1. A connector 102 is provided on the upper end of the inner wall of the oil tank 1 for connecting and... The air tube 2 is positioned, and its upper end is fitted onto the connector 102. The top end of the spring 3 abuts against the bottom end of the connector 102, and the bottom end of the spring 3 abuts against the top end of the movable part 5 to provide elasticity to the movable part 5, allowing it to move up and down within the air tube 2. The space between the outer wall of the air tube 2, the outer wall of the movable part 5, and the inner wall of the oil tank 1 forms an oil cavity 101 for storing e-liquid. The top of the oil tank 1 is equipped with a mouthpiece 103 for inhaling smoke. The top of the mouthpiece 103 has a smoking channel 104 extending to the bottom end of the connector 102 to draw smoke into the mouth. The air tube 2 forms a connection with the smoking channel 104. 4. A corresponding and interconnected smoke exhaust channel 201 is used for smoke exhaust. A receiving channel 501 corresponding and interconnected with the smoke exhaust channel 201 is also used for smoke exhaust. A sealing sleeve 7 is fitted onto the outer wall of the base 8. The base 8 is inserted into the bottom opening of the oil tank 1 to seal the oil cavity 101. The sealing sleeve 7 abuts against the inner wall of the oil tank 1 to seal the gap between the inner wall of the oil tank 1 and the outer wall of the base 8. A buckle hole 105 is provided on the outer wall of the oil tank 1. A buckle 801 is provided on the outer wall of the base 8 and is engaged in the buckle hole 105. The base 8 is fixed to the bottom opening of the oil tank 1 by the buckle 801 engaged in the buckle hole 105. Inside, the bottom of the base 8 has a plug-in channel 802 extending to the top of the base 8 for inserting the atomizing core 16 into the oil chamber 101. The lower end of the movable part 5 is fitted with an oil sealing ring 6. The plug-in channel 802 corresponds to the movable part 5. Under the elastic force of the spring 3, the lower end of the movable part 5 can extend into the plug-in channel 802 and abut against the upper end of the plug-in channel 802 through the oil sealing ring 6, so that the oil chamber 101 is isolated from the plug-in channel 802 to prevent e-liquid from flowing out, and the receiving channel 501 corresponds to and communicates with the plug-in channel 802. All the components are combined together to form the oil reservoir 9.

[0031] The atomizing core 16 includes: a second sealing ring 10, a third sealing ring 11, a fourth sealing ring 12, a heating core 13, an atomizing tube 14, and a conductive electrode 15. The atomizing tube 14 has an atomizing channel 1401 for airflow and to accommodate the heating core 13. The heating core 13 is installed inside the atomizing tube 14 to absorb and heat e-liquid. An oil inlet 1402 is provided on the outer wall of the atomizing tube 14 for introducing e-liquid into the heating core 13. An air inlet communicating with the atomizing channel 1401 is provided at the bottom end of the atomizing tube 14. 1403 is used to introduce air into the atomizing channel 1401. The second sealing ring 10 is sleeved on the upper end of the atomizing tube 14. The third sealing ring 11 and the fourth sealing ring 12 are sleeved on the lower end of the atomizing tube 14. The third sealing ring 11 is located above the oil inlet 1402, and the fourth sealing ring 12 is located below the oil inlet 1402. The conductive electrode 15 is installed at the bottom end of the atomizing tube 14 for conductive connection to the heating core 13. The heating core 13 is electrically connected to the conductive electrode 15. All components are combined together to form the atomizing core 16.

[0032] The atomizing core 16 is inserted into the lower end of the insertion / removal channel 802 through the upper end of the atomizing tube 14 and connected to the oil reservoir 9 to form an atomizing device. The top end of the atomizing tube 14 abuts against the bottom end of the sealing ring 6. When the atomizing device is in use, pressing the atomizing tube 14 causes the movable part 5 to move upward into the air tube 2. When the movable part 5 moves to abut against the step 202, the oil inlet 1402 on the atomizing tube 14 can be completely moved into the oil chamber 101. At the same time, the spring 3 is compressed and generates elastic force. The second sealing ring 10 and the third sealing ring 11 abut against the inner wall of the air tube 2, which can connect the outer wall of the atomizing tube 14 to the inner wall of the air tube 2. The gap between the lower end of the air tube 2 and the inner wall is sealed to prevent the e-liquid in the oil chamber 101 from entering the exhaust channel 201 through the gap between the two. The fourth sealing ring 12 abuts against the upper end of the plug-in channel 802, which can seal the gap between the lower end of the atomizing tube 14 and the upper end of the plug-in channel 802. The gap between the lower end of the atomizing tube 14 and the lower end of the inner wall of the air tube 2 is sealed to prevent the e-liquid in the oil chamber 101 from entering the plug-in channel 802 through the gap between the two. At the same time, the bottom end of the atomizing tube 14 is exposed at the lower end of the base 8. At this time, the e-liquid in the oil chamber 101 will enter the heating core 13 through the oil inlet 1402.

[0033] When the atomizing device is electrically connected to the power supply equipment (not shown), the power supply equipment will energize the heating core 13 through the conductive electrode 15. The heating core 13 can heat the e-liquid to produce smoke. The mouthpiece 103 allows external airflow to enter the atomizing channel 1401 through the air inlet 1403, and then carry the smoke from the receiving channel 501 into the exhaust channel 201. Finally, the smoke enters the user's mouth through the smoking channel 104 and is inhaled.

[0034] When there is still e-liquid in the oil chamber 101, if the atomizer core 16 malfunctions, pull out the bottom end of the atomizer tube 14. The atomizer core 16 can be pulled out of the oil chamber 101 through the insertion channel 802 for replacement. At this time, the movable part 5 will reset under the elastic force of the spring 3, and the gap between the lower end of the air tube 2 and the upper end of the movable part 5 will be sealed by the first sealing ring 4. The gap between the upper end of the insertion channel 802 and the lower end of the movable part 5 will be sealed by the oil sealing ring 6, which can prevent the e-liquid in the oil chamber 101 from flowing out of the insertion channel 802. Thus, the atomizer core 16 can be replaced when the atomizer is full of e-liquid.

[0035] When the atomizing device is not used for a long time, the atomizing core 16 can be pulled out from the insertion channel 802 and separated from the oil chamber 101 of the oil reservoir 9. This prevents the e-liquid in the oil chamber 101 from entering the heating core 13 through the oil inlet 1402. Long-term immersion in the heating core 13 will accelerate its corrosion, thereby affecting the service life of the heating core 13 and the flavor of the e-liquid.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this application and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
