[0037] Figures 1 to 12 The accompanying drawings are for this utility model.

[0038] This implementation provides an oil replenishment structure 20, please refer to... Figure 1 , 211 includes an oil tank shell 25 and a sealing seat 26 disposed at the lower end of the oil tank shell 25. The oil tank shell 25 is internally divided into a first inner cavity 201 and a second inner cavity 202. The sealing seat 26 is disposed at one end of the first inner cavity 201 to form an oil storage cavity 28, which is used to hold the atomizing matrix. The sealing seat 26 only seals the first inner cavity 201, so that the inner wall of the oil tank shell 25 and the sealing seat 26 form a closed cavity. At least one end of the second inner cavity 202 is an open cavity for installation with the atomizer 10. That is, part or all of the structure of the atomizer 10 is nested in the second inner cavity 202. The second inner cavity 202 serves as the space for installing the atomizer 10. The outer wall of the atomizer 10 abuts against the second inner cavity 202 (which can be understood as the atomizer 10 and the second inner cavity 202 being tightly fitted), making the connection between the atomizer 10 and the oil filling structure 20 more stable and preventing the atomizer 10 and the oil filling structure 20 from shifting to each other and causing oil leakage.

[0039] The sealing seat 26 is provided with an oil outlet 22 that communicates with the oil storage chamber 28. The oil outlet 22 is connected to the atomizer 10, and the atomizing matrix is ​​delivered to the atomizer 10 through the oil outlet 22. The lower end of the sealing seat 26 is a flat structure, and the oil outlet 22 is set on the flat structure, so that the oil outlet 22 has stable contact with the puncture part 113 of the atomizer 10 and is not easy to shift, thus preventing oil leakage at the contact point between the oil outlet 22 and the atomizer 10.

[0040] The first inner cavity 201 and the second inner cavity 202 can be arranged concentrically or eccentrically, that is, the first inner cavity 201 surrounds the outside of the second inner cavity 202. At the same end, the first inner cavity 201 is provided with a sealing seat 26, and the second inner cavity 202 is an open end, which is used to insert the atomizer 10.

[0041] In other embodiments, the first inner cavity 201 and the second inner cavity 202 may also be arranged side by side. The sealing seat 26 is also arranged at the lower end of the first inner cavity 201, so that the first inner cavity 201 forms an oil storage chamber 28. The second inner cavity 202 is an open cavity for direct insertion of the atomizer 10. The oil outlet 22 is arranged side by side with the second inner cavity 202.

[0042] A sealant 27 is provided between the sealing seat 26 and the port of the first inner cavity 201. The sealant 27 has a sealing wall that contacts the outer wall of the second inner cavity 202. The sealant 27 is first installed to the open end of the first inner cavity 201, and then the sealing seat 26 is installed, thus sealing the sealing seat 26. The sealant 27 is used to seal the first inner cavity 201. The sealant 27 has a through hole at the oil outlet 22, allowing the oil outlet 22 to communicate with the second inner cavity 202. The outer wall of the sealant 27 abuts against the inner wall of the first inner cavity 201 and the outer wall of the second inner cavity 202, thus forming a seal in the first inner cavity 201.

[0043] An extension 251 is provided inside the oil tank shell 25. The extension 251 extends from one end to the other inside the oil tank shell 25, forming a first inner cavity 201 and a second inner cavity 202 inside the oil tank shell 25. It can be understood that the cross-section of the oil tank shell 25 is an annular plane, with the middle annular cavity being the second inner cavity 202 and the outer annular cavity being the first inner cavity 201. The extension 251 extends from one end of the oil tank shell 25 along the inner cavity of the oil tank shell 25 towards the other end, and does not converge at the end of the extension 251. Therefore, one end of the oil tank shell 25 is open, meaning one end of the first inner cavity 201 and the second inner cavity 202 is designed to be open.

[0044] An air outlet 24 is provided at one end of the oil tank shell 25 where the extension portion 251 begins to extend; that is, the air outlet 24 is provided at the end of the oil tank shell 25 away from the sealing seat 26. The air outlet 24 communicates with the second inner cavity 202, allowing the aerosol of the atomizer 10 installed in the second inner cavity 202 to be discharged from the air outlet 24. After the oil replenishment structure 20 is installed with the atomizer 10, part or all of the outer side of the atomizer 10 is nested in the second inner cavity 202 of the oil replenishment structure 20. The mouthpiece 114 of the atomizer 10 is connected to the air outlet 24 of the oil replenishment structure 20, thus forming two outlets. The air outlet 24 has a conduit portion 241 extending within the second inner cavity 202. The conduit portion 241 is inserted into the mouthpiece 114, which not only guides the airflow but also serves a positioning function when the atomizer 10 is installed with the oil replenishment structure 20.

[0045] Preferably, the oil tank shell 25 and the vent nozzle 24 are an integral structure. The vent nozzle 24 is part of the oil tank shell 25 and is formed in one piece by injection molding.

[0046] In other embodiments, please refer to Figure 3 , 12 The oil tank shell 25 does not have an outlet 24. The mouthpiece 114 of the atomizer 10 extends from one end of the oil tank shell 25, and inhalation is performed directly using the mouthpiece 114. Therefore, the oil tank shell 25 has a cylindrical structure and is directly nested on the outside of the atomizer 10. After the oil tank shell 25 is installed in the atomizer 10, the mouthpiece 114 of the atomizer 10 protrudes from one end of the second inner cavity 202 and protrudes from the end of the oil tank shell 25. Specifically, the extension 251 extends from one end of the oil tank shell 25 to the other end, forming a first inner cavity 201 and a second inner cavity 202. The first inner cavity 201 is open at one end, and the second inner cavity 202 is open at both ends. If the first inner cavity 201 and the second inner cavity 202 are designed concentrically, the cross-section of the oil tank shell 25 is also an annular structure; if the first inner cavity 201 and the second inner cavity 202 are designed side by side, the first inner cavity 201 and the second inner cavity 202 are parallel cavities.

[0047] Please see Figures 1 to 210 to 11, a protective membrane 23 is provided on the sealing seat 26 at the oil outlet 22. When the refill structure 20 leaves the factory, a protective membrane 23 is installed at the oil outlet end of the oil outlet 22 to prevent the atomizing matrix in the oil storage chamber 28 from flowing out. The protective membrane 23 is a thin film structure. When the refill structure 20 is connected to the atomizer 10, the puncture protrusion 113 of the atomizer 10 punctures the protective membrane 23, allowing the atomizing matrix in the refill structure 20 to flow to the oil storage chamber 13 by its own gravity through the refill channel 112. Puncture of the protective membrane 23 during use not only ensures the freshness of the atomizing matrix but also ensures the sealing of the refill structure 20. The protective membrane 23 is made of soft adhesive, allowing the puncture protrusion 113 to be effectively punctured.

[0048] A diaphragm seat 29 is located near the oil outlet 22 on the sealing seat 26. A protective membrane 23 is mounted on the diaphragm seat 29. The diaphragm seat 29 is specifically designed for installation, making it convenient to mount the protective membrane 23 onto the sealing seat 26. If the protective membrane 23 were designed separately, it would be difficult to install onto the sealing seat 26, and the protective membrane 23 would also be more difficult to process. Therefore, mounting the protective membrane 23 on the diaphragm seat 29 and then mounting it onto the sealing seat 26 via the diaphragm seat 29 not only facilitates the installation of the protective membrane 23 onto the sealing seat 26 but also makes the protective membrane 23 easier to process.

[0049] Preferably, the protective membrane 23 and the membrane seat 29 are an integral structure, meaning the protective membrane 23 is part of the membrane seat 29. After the membrane seat 29 is installed onto the sealing seat 26, the protective membrane 23 is located on the oil outlet 22. Therefore, the integral structure of the protective membrane 23 and the membrane seat 29 facilitates the installation of the protective membrane 23 onto the oil outlet 22. Simultaneously, the integral structure of the protective membrane 23 and the membrane seat 29 facilitates the processing of the protective membrane 23.

[0050] Specifically, the sealing seat 26 has an installation cavity 261 located at the oil outlet 22. A membrane seat 29 is disposed within the installation cavity 261. The membrane seat 29 is embedded into the installation cavity 261 from the lower end of the sealing seat 26, and the protective membrane 23 is located at the oil outlet 22. The sealing seat 26 has an installation cavity 261 for installing the membrane seat 29, which serves to position the protective membrane 23 at the oil outlet 22. The installation cavity 261 is located on the outward-facing side of the sealing seat 26, allowing the membrane seat 29 to be installed from the outside of the sealing seat 26 into the installation cavity, facilitating installation. Furthermore, the puncture protrusion 113 punctures the protective membrane 23 from the outside; when the protective membrane 23 is subjected to puncture force, the membrane seat 29 will not shift due to the puncture force, preventing oil leakage caused by displacement of the membrane seat 29.

[0051] Preferably, the film base 29 is made of silicone, and the protective film 23 and the film base 29 are integrally injection molded. The protective film 23 is a relatively thin part, and the integral molding process ensures the quality of the protective film 23.

[0052] The membrane seat 29 is provided with a membrane hole 291, and a protective membrane 23 is disposed within the membrane hole 291. When the atomizer 10 is assembled with the oil replenishment structure 20, the piercing protrusion 113 penetrates through the membrane hole 291 and punctures the protective membrane 23, allowing the atomizing matrix to flow into the oil storage tank 13 from the oil inlet 116 and the oil replenishment channel 112. The inner diameter of the membrane hole 291 is slightly smaller than the outer diameter of the piercing protrusion 113, so that a sealing structure is formed between the piercing protrusion 113 and the membrane hole 291 to prevent leakage.

[0053] Please see Figures 1 to 2 A bottom cover 252 is provided on the outside of the sealing seat 26. The bottom cover 252 is fixedly connected to the oil tank shell 25 so that the sealant 27 and the sealing seat 26 are fixed to the lower end of the oil tank shell 25.

[0054] For preferred options, please refer to [link / reference]. Figures 1 to 2 The sealing seat 26 is provided with a buckle 262 at the end where it connects to the atomizer 10, and the atomizer 10 is provided with a buckle hole, making the connection between the atomizer 10 and the filler structure 20 more convenient and reliable. The buckle 262 extends out of the bottom cover 252 and protrudes from the lower end of the filler structure 20.

[0055] In other embodiments, the sidewall of the oil replenishment structure 20 is provided with capillary pores, which can ventilate the inner cavity of the oil replenishment structure 20 when the atomized matrix flows out of the oil replenishment structure 20, preventing the atomized matrix from failing to flow out of the oil outlet 22 due to pressure imbalance in the oil replenishment structure 20.

[0056] An atomizer 10, please refer to Figures 4 to 7 The atomizing shell 11 includes an atomizing housing 11 and an atomizing core 12 disposed within the atomizing housing 11. The atomizing core 12 is used to atomize the atomizing matrix into an aerosol. The atomizing housing 11 has an oil reservoir 13 for holding the atomizing matrix. The oil reservoir 13 has an atomizing channel 14 extending through both ends of the oil reservoir 11. The atomizing core 12 is disposed within the atomizing channel 14, and the oil inlet end of the atomizing core 12 is connected to the oil reservoir 13. Air enters from one end of the atomizing channel 14, and the atomizing matrix atomized into an aerosol by the atomizing core 12 is discharged from the other end of the atomizing channel 14. The atomizing housing 11 is provided with a mounting platform 111, which is located near the lower end of the atomizing housing 11 to facilitate installation with the oil replenishment structure 20. The mounting platform 111 is located on the outside of the atomizing housing 11 so that the oil replenishment structure 20 can be fitted onto the outside of the atomizing housing 11.

[0057] The atomizer 10 is equipped with a refill channel 112 for replenishing the atomizing matrix, meaning the refill structure 20 can refill the oil reservoir 13 through the refill channel 112. The inlet end of the refill channel 112 is located on the mounting platform 111. The refill channel 112 communicates with the oil reservoir 13, allowing the atomizing matrix entering from the outside to reach the atomizer core 12 for atomization. The mounting platform 111 is located at the lower end of the atomizer shell 11 for easy installation with the refill structure 20, and the atomizing matrix of the refill structure 20 can be replenished through the refill channel 112. When the atomizing matrix in the oil reservoir 13 is depleted, the refill structure 20 can replenish the oil reservoir 13 from the outside, effectively extending the atomizer's lifespan and increasing its usability. Furthermore, due to the split design of the refill structure 20, it also maintains the freshness of the atomizing matrix and prevents atomizer leakage.

[0058] In another embodiment, the atomizer 10 does not have an oil reservoir 13. During atomization, the atomizing matrix is ​​supplied to the atomizer 10 by the oil replenishment structure 20. After the oil replenishment structure 20 is installed in the atomizer 10, the atomizing matrix within the oil replenishment structure 20 flows through the oil replenishment channel 112 to the atomizer coil 12 of the atomizer 10 for atomization. That is, the atomizer 10 does not have a separate oil reservoir and cannot work independently. The atomizing matrix can only enter the atomizer 10 after the oil replenishment structure 20 is installed, thus forming a working atomizer. The atomizer 10 and the oil replenishment structure 20 are designed separately. The oil replenishment structure 20 is sealed before it is installed in the atomizer 10, thus maintaining the freshness of the atomizing matrix in the oil replenishment structure 20.

[0059] Mounting platform 111 is formed by a radially extending shoulder of atomizer shell 11. The oil replenishment structure 20 is fitted onto the outside of atomizer shell 11, with its lower end assembling with the shoulder. The oil replenishment structure 20 is installed from the upper end of atomizer shell 11 downwards, thereby bringing its lower end into contact with the surface of mounting platform 111. The surface of mounting platform 111 is planar, and one end of oil replenishment channel 112 is positioned on this planar structure.

[0060] Please see Figure 6 , 7A mounting base 18 is provided at the lower end of the atomizing shell 11. The mounting base 18 is used to seal the lower end of the atomizing shell 11, forming an oil reservoir 13 inside the atomizing shell 11. At the same time, the mounting base 18 serves as a base plate for fixing components such as conductive components and the atomizing coil 12. The mounting base 18 and the atomizing shell 11 form the oil reservoir 13. The lower end of the atomizing shell 11 is designed to be open, and the mounting base 18 is installed at the open end. Inside the atomizing shell 11, there is a mounting tube 15 for installing the atomizing coil 12. One end of the mounting tube 15 is connected to one end of the atomizing shell 11, and the other end is connected to the mounting base 18. Therefore, the inner cavity of the mounting tube 15 forms an atomization channel 14. One end of the mounting tube 15 located at the mounting base 18 is the air inlet end, and the other end is the air outlet end. The atomizing coil 12 is located between the air outlet end and the air inlet end inside the mounting tube 15, that is, the atomizing coil 12 is located inside the atomization channel 14. The mounting base 18, the atomizing shell 14, and the mounting tube 15 form an oil storage chamber 13. The mounting tube 15 is provided with an oil passage window at the installation position of the atomizing core 12, so that the atomizing matrix of the oil storage chamber 13 can flow to the atomizing core 12 through the oil passage window.

[0061] In another configuration, the mounting tube 15 is connected to the air outlet end of the atomizing core 12, meaning the mounting tube 15 is attached to the end of the atomizing core 12 near the mouthpiece 114. In this configuration, one end of the atomizing core 12 is connected to the mounting base 18, and the other end is connected to the mounting tube 15, allowing the other end of the mounting tube 15 to connect to the atomizing shell 11. Therefore, the inner cavities of the atomizing core 12 and the mounting tube 15 form an atomization channel 14.

[0062] Please see Figure 6 , 7 11. The oil storage tank 13 is equipped with an oil storage cotton 16 for storing the atomizing matrix. The oil storage cotton 16 in the oil storage tank 13 can suppress the flow of the atomizing matrix and reduce the risk of leakage. The atomizing channel 14 runs through the oil storage cotton 16, and the atomizing core 12 is located in the atomizing channel 14. Therefore, the atomizing matrix in the oil storage cotton 16 can flow to the atomizing core 12 through permeation. The oil replenishment channel 112 is located at one end of the oil storage tank 13 and is connected to the oil storage cotton 16. That is, one end of the oil replenishment channel 112 is connected to the oil storage tank 13. When the oil replenishment structure 20 replenishes the atomizing matrix to the oil storage tank 13, the atomizing matrix can flow to the oil storage cotton 16 through the oil replenishment channel 112.

[0063] Please refer to Figures 4 to 711. One end of the oil replenishment channel 112 is located on the surface of the mounting platform 111, and the other end is connected to the oil storage tank 13. The oil replenishment channel 112 is a channel for externally replenishing the atomizing matrix to the oil storage tank 13. Therefore, one end is located on the surface of the mounting platform 111 for easy connection with the oil replenishment structure 20, and the other end is connected to the oil storage tank 13 to directly replenish the atomizing matrix to the oil storage tank 13. The oil inlet direction of the oil replenishment channel 112 is perpendicular to the surface of the mounting platform 11. After the oil replenishment structure 20 is installed on the mounting surface 111, the atomizing matrix in the oil replenishment structure 20 can flow into the oil storage tank 13 through its own oil replenishment channel 112.

[0064] In one embodiment, a gap is formed between the inner wall of the mounting platform 111 and the mounting base 18, and this gap forms part of the oil replenishment channel 112. An oil inlet 116 communicating with the gap is provided on the surface of the mounting platform 111, and the oil reservoir 13 communicates with the gap, thus forming the oil replenishment channel 112. The oil replenishment channel 112 is formed through the gap between the inner wall of the mounting platform 111 and the mounting base 18, resulting in a simple and compact structure and convenient installation.

[0065] In other embodiments, the oil inlet 116 and the oil storage tank 13 are connected by an oil guide pipe. The separate design of the oil guide pipe effectively prevents oil seepage or leakage from the oil replenishment channel 112.

[0066] When the atomizer 10 is used alone or at the factory, the oil inlet 116 is equipped with a plug to prevent the atomizing matrix in the oil reservoir 13 from overflowing. When the atomizer 10 is assembled with the oil replenishment structure 20, the plug is removed.

[0067] Please see Figure 6 , 7 A first sealing element 17 is provided between the mounting base 18 and the oil storage tank 13. The first sealing element 17 is located at the lower end of the oil storage tank 13 and between the atomizing shell 11 and the mounting base 18, serving to seal the oil storage tank 13. This can be understood as follows: the first sealing element 17 is located at the lower end of the atomizing shell 11, sealing the inner cavity of the oil storage tank 13. Then, the mounting base 18 is located at the lower end of the atomizing shell 11, outside the first sealing element 17. The mounting base 18 is fixed to the atomizing shell 11, and simultaneously, the mounting base 18 also fixes the first sealing element 17. In terms of installation sequence, the first sealing element 17 is first installed into the open end at the lower end of the atomizing shell 11, and then the mounting base 18 is fixed to the atomizing shell 11.

[0068] Please see Figure 7A gap is formed between the first seal 17 and the atomizing shell 11, forming part of the aforementioned oil replenishment channel 112. The gap between the first seal 17 and the atomizing shell 11 effectively improves the sealing performance of the oil replenishment channel 112. After the first seal 17 is installed at the lower end of the atomizing shell 11, a gap or cavity is formed between the inward-facing side of the first seal 17 and the inner wall of the atomizing shell 11. One side of this gap or cavity communicates with the oil inlet 116, and the other side communicates with the oil storage tank 13. Another part of the oil replenishment channel 112 is located on the atomizing shell 11, specifically the oil inlet 116. The oil replenishment channel 112 is formed through the gap between the first seal 17 and the atomizing shell 11 and the oil inlet 116 on the atomizing shell 11.

[0069] Please refer to Figure 6 , 7 11. A buffer cotton 115 is installed in the oil replenishment channel 112 to prevent the atomized matrix in the oil replenishment structure 20 from flowing too quickly into the oil storage tank. The buffer cotton 115 is installed in the gap or cavity formed between the first seal 17 and the inner wall of the atomizing shell 11. The buffer cotton 115 fills the gap or cavity. After the atomized matrix flows out of the oil replenishment structure 20, it is permeated by the buffer cotton 115 and then flows into the oil storage tank 13. The buffer cotton 115 has the function of reducing the flow rate of the atomized matrix, preventing excessive pressure of the atomized matrix in the oil replenishment structure 20 from flowing into the oil storage tank 13 and causing oil leakage.

[0070] Please see Figures 6 to 8 The first sealing element 17 is provided with an air inlet 171 communicating with the atomizing channel 14. The lower end of the mounting tube 15 or the atomizing core 12 is positioned close to the air inlet 171, which can be considered as one end of the atomizing channel 14. The first sealing element 17 is also provided with a mounting hole 172 for mounting the mounting tube 15 or the atomizing core 12. The lower end of the mounting tube 15 or the atomizing core 12 is fixed in the mounting hole 172 to secure the atomizing core 12. In addition, the mounting hole 172 provided in the first sealing element 17 improves the sealing performance between the mounting tube 15 or the atomizing core 12 and the first sealing element 17 after the mounting tube 15 or the atomizing core 12 is installed in the first sealing element 17, thereby improving the sealing performance of the oil reservoir 13. The air inlet 171 and the mounting hole 172 are interconnected and can also be concentrically arranged, allowing air to enter the atomizing core 12 from the air inlet 171 after the atomizing core 12 is installed. Preferably, the diameter of the air inlet 171 is smaller than the diameter of the mounting hole 172, so that a step is formed between the air inlet 171 and the mounting hole 172. Therefore, the end of the mounting tube 15 or the atomizing core 12 stops on the step, so that the mounting tube 15 or the atomizing core 12 can be firmly installed on the first seal 17 to avoid oil leakage.

[0071] For preferred options, please refer to [link / reference]. Figures 6 to 8 The first sealing element 17 has a groove 173 on the side facing the atomizing shell 11. When the first sealing element 17 and the atomizing shell 11 are installed together, the lower end of the atomizing shell 11 has a protrusion that is inserted into the groove 173. This not only increases the rigidity of the first sealing element 17, but also facilitates the positioning of the first sealing element 17 during installation, and also improves the sealing performance between the atomizing shell 11 and the first sealing element 17.

[0072] For preferred options, please refer to [link / reference]. Figures 6 to 9 The first sealing element 17 has a recess 174 on the side facing the mounting base 18, so that the first sealing element 17 and the mounting base 18 form a cavity, which is called the first cavity 19. The first cavity 19 communicates with the air inlet 171 of the first sealing element 17, and air is supplied to the atomizing core 12 through the first cavity 19 and the air inlet 171. The cross-sectional area of ​​the first cavity 19 is larger than that of the air inlet 171, and the air inlet 171 is located above the first cavity 19, which facilitates the collection of oil leakage or condensate in the first cavity 19. The mounting base 15 is provided with an air inlet 151 communicating with the first cavity 19, and the air inlet 151 is located on the inner wall of the first cavity 19. In the working state, air enters the first cavity 19 through the air inlet 151, and then enters the atomizing channel 14 through the air inlet 171.

[0073] Preferably, the first cavity 19 is provided with oil-absorbing cotton 191 to absorb condensate flowing out of the atomization channel 14, as well as leaked or un-atomized atomized matrix. The oil-absorbing cotton 191 is located in the first cavity 19 directly below the air inlet 171.

[0074] Please see Figure 4 , 6 7. The atomizing shell 11 has a piercing protrusion 113 at the oil inlet end of the oil replenishment channel 112. The piercing protrusion 113 is oriented in the same direction as the oil replenishment structure 20. The piercing protrusion 113 is a tubular structure, with one end of the tube communicating with the oil replenishment channel 112, and the outer end of the tube being the oil inlet end of the oil replenishment channel 112. The end of the piercing protrusion 113 has a piercing part for piercing the protective film 23 at the oil outlet end of the oil replenishment structure 20. The piercing protrusion 113 protrudes from the surface of the mounting platform 111 and is perpendicular to the surface of the mounting platform 111. Preferably, there are two piercing protrusions 113 to ensure that the atomizing matrix of the oil replenishment structure 20 can flow sufficiently into the oil storage tank 13.

[0075] Preferably, the mounting platform 111 divides the atomizing shell 11 into two sections. The lower section is the installation space for components such as the mounting base 18 and the first sealing element 17, and the upper end is the oil storage tank 13. The cross-sectional area of ​​the lower section is larger than that of the upper section, so the mounting platform 111 forms a shoulder structure.

[0076] Please see Figures 4 to 7A nozzle 114 is provided at the other end of the mounting platform 111, where the atomizing shell 11 is located. The nozzle 114 is connected to the atomizing channel 14. Preferably, the nozzle 114 and the atomizing shell 11 are an integral structure.

[0077] For preferred options, please refer to [link / reference]. Figure 5 , 6 An electrical connection block 181 is provided on the outer side of the mounting base 18, and the atomizing core 12 is electrically connected to the electrical connection block 181 to provide power to the atomizing core 12. The electrical connection block 181 is embedded in the outer side of the mounting base 18 and exposed on the surface of the mounting base 18, so that the atomizer is electrically connected to the power output terminal of the power supply device.

[0078] For preferred options, please refer to [link / reference]. Figure 5 A magnet 182 is provided on the outer side of the mounting base 18 for connecting the atomizer and the power supply device. The atomizer and the power supply device are connected by the magnet 182, which facilitates the assembly and disassembly of the two devices and makes them convenient to use. The magnetic force of the magnet 182 tightly attracts the atomizer and the power supply device, so that the electrical connection block 181 can have a stable electrical contact with the power supply device.

[0079] A mounting platform 111 is provided near the lower end of the atomizer 10, and a refill channel 112 is provided on the mounting platform 11. This allows the refill structure 20 to be nested outside the atomizer 10, with one end of the atomizer 10 connected to the mounting platform 111. The refill structure 20 replenishes the e-liquid tank 13 through the refill channel 112. The refill structure 20 and the atomizer 10 are designed separately. When the atomizer 10's atomizing matrix is ​​about to run out, the refill structure 20 is nested outside the atomizer 10 to replenish the atomizer 10, extending the lifespan of the atomizer 10 while ensuring the freshness of the atomizing matrix in the refill structure 20.

[0080] An atomizing device, please refer to Figures 1 to 2 10 to 11 include the aforementioned atomizer 10 and a replenishment structure 20. The replenishment structure 20 is used to replenish the atomizing matrix to the atomizer 10. The second inner cavity 202 of the replenishment structure 20 is used to house the atomizer 10. The second inner cavity 202 is a cavity with one open end. The atomizer 10 is installed into the second inner cavity 202 from the open end of the replenishment structure 20, forming an atomizer 10 nested within the second inner cavity 202. The end of the replenishment structure 20 is connected to the mounting platform 111 of the atomizer 10. The replenishment channel 112 provided on the mounting platform 111 communicates with the oil outlet end of the replenishment structure 20. The mounting platform 111 not only serves as a mounting platform, allowing the end of the replenishment structure 20 to abut against the mounting platform 111, but also as a transition structure for the atomizer 10 to replenish the atomizing matrix from the replenishment structure 20.

[0081] The oil outlet 22 at the end of the oil replenishment structure 20 is connected to the oil replenishment channel 112 of the atomizer 10. The piercing protrusion 113 of the atomizer shell 11 is inserted into the oil outlet 22, replenishing the atomizing matrix to the oil storage tank 13 through the oil replenishment channel 112. The oil storage tank 13 of the atomizer 10 itself has an oil storage function and can supply the atomizing matrix to the atomizer coil 12. However, the oil storage tank 13 has a small volume, and the storage capacity of the atomizing matrix is ​​limited. If the atomizing matrix of the atomizer 10 is discarded after it is depleted, it will cause great waste. Therefore, the oil replenishment structure 20 is set up, which can not only effectively extend the service life of the atomizer 10, but also avoid waste. The oil replenishment structure 20 can be designed to be packaged separately. When the atomizing matrix of the atomizer 10 is about to be depleted, the oil replenishment structure 20 is installed on the atomizer 10, thus maintaining the freshness of the atomizing matrix.

[0082] Since the protective membrane 23 is set on the membrane base 29, it facilitates the sealing of the oil replenishment structure 20 and prevents oil leakage. Existing large-capacity oil cup structures, due to their large oil storage capacity, are prone to oil leakage in some special environments, such as high temperature and low pressure. This application solves the oil leakage problem by nesting a separately designed oil replenishment structure 20 outside the atomizer 10, which not only preserves the atomization matrix but also solves the oil leakage problem.

[0083] Compared with the prior art, this utility model provides a first inner cavity 201 and a second inner cavity 202 within the oil tank shell 25. The first inner cavity 201 and the sealing seat form an oil storage cavity 28. The second inner cavity 202 is designed to be open, used to accommodate all or part of the atomizer 10. During installation, part or all of the atomizer 10 is directly inserted into the second inner cavity 202, and the outer wall of the atomizer 10 contacts the inner wall of the second inner cavity 202, making the connection between the atomizer 10 and the oil replenishment structure 20 relatively stable. The sealing seat 26 and the first inner cavity 201 form the oil storage cavity 28, and the atomizing matrix is ​​replenished to the atomizer 10 through the oil outlet 22.

[0084] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
