[0050] Please refer to Figures 1 to 5 , and now the electronic atomizer provided in this embodiment will be described. In this embodiment, the electronic atomizer 100 includes a cartridge 10 and a main body assembly 5. The main body assembly 5 adopts a long strip-shaped battery rod structure, and the cartridge 10 and the main body assembly 5 are preferably connected in a magnetic attraction manner.

[0051] Specifically, the main body assembly 5 includes a housing 53, a control module (not shown in the figure), a power module 52, an electrical connector 54, and a bracket 51. One end of the housing 53 has an opening, and the other end is provided with an air inlet 531. The control module and the power module 52 are fixed to the bracket 51 by a snap structure and then inserted into the housing 53. The top of the bracket 51 is a plate-shaped structure and encloses a receiving groove 55 with a part of the inner wall of the housing 53. A magnetic member 6 is attached to the bottom of the receiving groove 55. Correspondingly, a magnetic member 6 is provided at the bottom of the cartridge 10. One end of the electrical connector 54 is respectively connected to the power module 52 and the control module, and the other end is exposed to the bottom of the receiving groove 55. Of course, an electrical connector 54 is also provided at the bottom of the cartridge 10 and is connected to the atomization core 3. When the cartridge 10 is placed in the receiving groove 55, the two magnetic members 6 interact with each other, so that the cartridge 10 is firmly fixed in the housing 53, and the electrical connectors 54 are in contact with each other, so that the cartridge 10 and the main body assembly 5 are electrically connected, and the control module controls the circuit channel between the atomization core 3 in the cartridge 10 and the power module 52 according to the trigger signal. For example, the battery rod is configured with an airflow sensor, and when the airflow sensor detects a change in the airflow inside the electronic atomizer 100, it will send a trigger signal to the control module.

[0052] Furthermore, as Figure 4 shown, the top of the bracket 51 is recessed downward to form a groove 511 with a trapezoidal cross-section. A ventilation hole 512 is provided at the top of the groove 511. The groove 511 is provided with staggered baffles 513. An oil-absorbing cotton (not shown in the figure) is padded at the bottom of the groove 511. Here, the plurality of baffles 513 arrange the groove 511 in a maze shape, extending the flow path of the condensate, improving the blocking effect, reducing the flow rate of the condensate, and the oil-absorbing cotton has good adsorption ability and can absorb the condensate, effectively preventing the condensate from leaking out through the ventilation hole 512 and the air inlet 531.

[0053] In one embodiment, the cartridge 10 includes an oil storage housing 1, an atomization assembly, and an oil guiding component 4. The oil storage housing 1 is used to store e-liquid. The oil guiding component 4 is disposed between the oil storage housing 1 and the atomization assembly and serves as a fluid transmission hub between the two.

[0054] Specifically, please refer to Figures 2 to 6 , the oil storage housing 1 has a first liquid storage cavity 111 and an air outlet channel 112. The first liquid storage cavity 111 is provided with at least one liquid outlet hole 121, and a seal 13 covers the liquid outlet hole 121. The oil storage housing 1 is made of PCTG material with high transparency and gloss, and users can observe the remaining amount of e-liquid in the oil storage housing 1 at any time. The atomization assembly is disposed at the bottom of the oil storage housing 1, and its shape is substantially the same as that of the oil storage housing 1. The atomization assembly includes an atomization housing 2 and an atomization core 3. The atomization housing 2 has a second liquid storage cavity 25 and an air inlet hole 26. The atomization core 3 is installed in the second liquid storage cavity 25, and a cylindrical atomization channel 36 is formed inside the atomization core 3. When the oil storage housing 1 is assembled to the atomization assembly, the atomization channel 36, the air outlet channel 112, and the air inlet hole 26 are coaxially distributed. The oil guiding component 4 can be a transparent rigid plastic tube, a metal tube, or a top-opening valve body. One end of the oil guiding component 4 adjacent to the atomization housing 2 is configured as the bottom end, and conversely, the other end of the oil guiding component 4 is the top end. The top end of the oil guiding component 4 has a tapered unsealing portion 46, and the bottom end of the oil guiding component 4 extends into the second liquid storage cavity 25 of the atomization housing 2. Under the action of an external force, the top end of the oil guiding component 4 can open the seal 13 of the oil storage housing 1. With the oil guiding component 4 as the transmission hub, the first liquid storage cavity 111 and the second liquid storage cavity 25 are interconnected.

[0055] Compared with other e-cigarettes, the present invention adopts a split chamber design. When not in use, the first liquid storage cavity 111 stores e-liquid in a sealed manner, and the second liquid storage cavity is not completely sealed and may not store e-liquid or store a small amount of liquid. When the second liquid storage cavity 25 stores e-liquid, absorbent cotton is filled on the outer peripheral side of the atomization core 3 in the second liquid storage cavity 25. The absorbent cotton adsorbs e-liquid through capillary action, thereby significantly reducing the flow rate of e-liquid and preventing e-liquid from gushing out from the atomization channel 36, fundamentally eliminating the risk of liquid leakage caused by temperature, air pressure, and vibration during transportation and storage, and completely solving the problem of liquid leakage of existing e-cigarettes. After being opened for use, the penetration rate of e-liquid is limited by the oil guiding component 4, effectively avoiding oil leakage from the atomization core 3 and backflow of condensate, ensuring stable atomization effect, and improving the user experience. The split structure, while ensuring large-capacity oil storage, optimizes the cavity layout and the design of the oil guiding component 4, makes full use of the internal space, extends the product's battery life, reduces the trouble of users frequently refilling e-liquid, meets the long-term use requirements, and at the same time avoids the potential threat of spilled e-liquid to the surrounding ecological environment, combining economic benefits and environmental protection value.

[0056] In one embodiment, the atomizing housing 2 includes an upper housing 21 and a base 22. The inner top wall of the upper housing 21 extends downward to form an annular side wall 23. The base 22 is sealingly connected to the bottom opening of the upper housing 21. The inner wall of the annular side wall 23 and the base 22 jointly define a second liquid storage cavity 25. An air outlet hole 212 is provided at the middle position of the top of the upper housing 21. The atomizing core 3 is vertically fixed in the middle of the second liquid storage cavity 25. The atomizing core 3 has an atomizing channel 36 distributed longitudinally. The atomizing channel 36 is coaxially distributed with the air outlet hole 212. Two mounting holes 211 penetrating the top are symmetrically distributed on the top of the upper housing 21. The two mounting holes 211 are respectively located outside the air outlet hole 212. Correspondingly, two liquid outlet holes 121 are provided at the bottom of the oil storage housing 1. Each liquid outlet hole 121 is covered with a seal 13. The atomizing assembly further includes two tubular oil guiding members 4. Each oil guiding member 4 is fixedly installed in the mounting hole 211 by interference fit. As Figure 1 shown, the atomizing core 3 is arranged at the middle position of the second liquid storage cavity 25. Oil guiding members 4 are respectively arranged on both sides of the atomizing core 3, that is, "oil enters from both sides and is atomized in the middle". The e-liquid flowing into the second liquid storage cavity through the two oil guiding members 4 can quickly diffuse around, so as to ensure that the periphery of the atomizing core 3 is soaked with e-liquid to avoid heating and caking of the core. Of course, in some embodiments, a plurality of oil inlet channels can be distributed at intervals around the periphery of the atomizing core 3, which is not limited here.

[0057] In addition, in some embodiments, the liquid outlet holes 121 and the mounting holes 211 are respectively arranged on the sides of the oil storage housing 1 and the atomizing housing 2. By arranging the liquid outlet holes 121 on the side of the oil storage housing 1, the oil storage housing 1 is blow-molded, and its bottom and top can be sealed, and the side wall is open, so as to ensure the sealing performance of the oil storage housing 1 and reduce the risk of liquid leakage. This structural design not only ensures the sealing performance of the oil storage housing 1 and effectively reduces the risk of liquid leakage, but also makes a relatively independent and stable liquid storage space formed inside the oil storage housing 1, providing a reliable guarantee for e-liquid storage. At the same time, the mounting holes 211 are arranged on the side of the atomizing housing 2. This layout is more convenient in the assembly process, improves production efficiency, and can better cooperate with components such as liquid guiding members during use to ensure the smooth transmission of e-liquid, further improving the overall performance and user experience of the product.

[0058] In one embodiment, please refer to Figure 2 and Figure 3, the oil tank housing 1 includes an outer shell 11, a sealing seat 12 and a sealing member 13. The outer shell 11 is formed by molding transparent or translucent plastic or glass. A longitudinally extending cylindrical side wall is formed in the middle of the outer shell 11, and the cylindrical side wall is the air outlet channel 112. The sealing seat 12 is embedded in the bottom opening of the outer shell 11. A liquid outlet hole 121 is provided at the bottom of the sealing seat 12, and the sealing member 13 is fixedly sealed at the liquid outlet hole 121. The sealing member 13 is in the shape of a thin film, which can not only seal the e-liquid, but also be easily pierced during use. The sealing member 13 and the sealing seat 12 can be provided independently. For example, the sealing seat 12 is connected to the sealing seat 12 by gluing. Of course, the sealing member 13 can also be integrally processed with the sealing seat 12, which can reduce the assembly process of the sealing member 13 and ensure the sealing performance. When the sealing seat 12 and the sealing member 13 are integrally formed, a pre-breaking part or a thinning design can be provided in the area of the sealing seat 12 corresponding to the liquid outlet hole 121, so that the oil guiding component 4 can pierce the sealing member 13.

[0059] Furthermore, the oil guiding component 4 can be formed by molding a metal pipe fitting. Since metal has a greater hardness than plastic, the oil guiding component 4 is more likely to pierce the sealing member 13. The unsealing part 46 at the top of the oil guiding component 4 is in the shape of a conical tip. When an external force acts, most of the pressure will concentrate on the unsealing part 46, so the sealing member 13 can be easily pierced.

[0060] In one embodiment, a receiving cavity 213 is formed by extending upward from the top of the upper housing 21 for accommodating the oil tank housing 1. The oil tank housing 1 is detachably installed in the receiving cavity 213 by means of threaded connection, snap fit, magnetic attraction, etc. A sealing ring 28 is provided at the port of the receiving cavity 213. The sealing ring 28 is made of fluororubber material and has strong deformation ability, which can fill the gap at the connection between the upper oil tank shell and the upper housing 21 to avoid air leakage.

[0061] Furthermore, at least two elastic buckles 14 are symmetrically provided at the bottom of the oil tank housing 1, and the top end thereof has a 45° barb. At least two card slots 214 are provided at the corresponding positions at the bottom of the upper housing 21, and a 15°-30° conical flow guiding surface is provided at the port of the card slot 214. The elastic buckles 14 and the card slots 214 form a snap fit, significantly enhancing the connection stability between the oil tank housing 1 and the atomization assembly. Each card slot 214 penetrates the top wall of the upper housing 21, and the card slot 214 is located outside the annular side wall 23. At least two radially extending partition walls 27 are provided between the inner wall of the upper housing 21 and the outer wall of the annular side wall 23. The partition walls 27, the inner wall of the upper housing 21 and the outer wall of the annular side wall 23 jointly enclose at least two independent liquid storage tanks 24. This design ensures a firm connection between the oil tank housing 1 and the atomization assembly, preventing loosening or falling off, and at the same time realizing the recovery of condensate through the independent liquid storage tanks 24, improving the product performance and user experience.

[0062] Specifically, please refer to Figure 2 andFigure 5 , four elastic buckles 14 are provided at the bottom of the oil tank shell 1, and four card slots 214 are provided at the top of the atomizing shell 2 to match it. The interior of the atomizing shell 2 is enclosed by an annular side wall 23 and four partition walls 27 to form two independent liquid storage tanks 24 distributed symmetrically on the left and right. When the oil tank shell 1 is assembled to the atomizing shell 2, the elastic buckle 14 passes through the corresponding card slots 214 in turn, and its end extends vertically into the corresponding liquid storage tank 24. Since there is a certain gap at the connection between the oil tank shell 1 and the atomizing shell 2, there is a fault of the atomizing channel 36 between the oil tank shell 1 and the atomizing shell 2. During use, the condensate formed in the air outlet channel 112 slides along the gap to the bottom of the oil tank shell 1, and then gathers at the top of the receiving chamber 213. Both sides of the accommodating cavity 213 are provided with card slots 214 penetrating the top wall, and a liquid storage tank 24 is correspondingly provided below each card slot 214. There is a gap between the elastic buckle 14 and the card slot 214, and the conical guide surface of the card slot 214 has a good drainage effect. Therefore, the condensate or smoke oil leaked at the bottom of the oil tank shell 1 is gathered into the liquid storage tank 24 through the card slot 214, avoiding the leakage of liquid, thereby improving the reliability of the product and the user experience.

[0063] Furthermore, a liquid flow channel (not shown) is provided between the liquid storage tank 24 and the second liquid storage chamber 25. The smoke oil in the liquid storage tank 24 can smoothly flow back to the second liquid storage chamber 25, realizing liquid recycling, which not only reduces the waste of smoke oil, but also reduces the risk of environmental pollution caused by smoke oil leakage.

[0064] Furthermore, the oil tank housing 1 further includes a metal shell 15, which is mounted on the bottom of the oil tank housing 1, and a permanent magnet (not shown) is embedded on the top of the partition wall 27. When the oil tank housing 1 is assembled into the receiving cavity 213, an axial pressing force is generated between the permanent magnet and the metal shell 15, which increases the contact pressure between the oil tank housing 1 and the atomizing component, thereby reducing the gap at the connection between the two components and preventing air leakage from affecting the suction experience.

[0065] In one embodiment, the oil tank housing 1 has two independent first liquid storage chambers 111, and the atomizer assembly also has two second liquid storage chambers 25 that are independently arranged. For example, a sheet-like partition is vertically arranged in the middle of the oil tank housing 1 and the atomizer housing 2 in the atomizer assembly. The partition divides the oil tank housing 1 into the first liquid storage chamber 111, and divides the atomizer housing 2 into the second liquid storage chamber 25. The first liquid storage chamber 111 and the corresponding second liquid storage chamber 25 are distributed in mirror symmetry, and a directional fluid connection is established through the oil guide component 4. In order to meet the user's pursuit of multiple flavors, one of the first liquid storage chambers 111 can store ordinary tobacco oil, and the other first liquid storage chamber 111 can store flavorings that can stimulate the sense of smell.

[0066] In another embodiment, Figure 8As shown in the figure, the oil storage housing 1 includes a plurality of liquid storage chambers 16 stacked axially. Each liquid storage chamber 16 is provided with a liquid outlet hole 121 and a seal 13 at the bottom, and an air inlet / outlet channel 112 communicating with adjacent liquid storage chambers 16 is provided in the middle of each liquid storage chamber 16. Adjacent two liquid storage chambers 16 can be cooperated by means of snap fit, magnetic attraction or adhesion. The oil guiding component 4 is a telescopic multi-stage sleeve structure, and through holes 44 penetrating its side wall are provided at intervals along the height direction of the oil guiding component. A plurality of liquid storage chambers 16 are provided in the oil storage housing 1, and different atomization matrix flavors are stored in the liquid storage chambers 16. The oil guiding component 4 can adjust the extended height according to the number of the liquid storage chambers 16, so that the oil guiding component 4 can penetrate through each liquid storage chamber 16 to ensure the smoothness of the liquid channel. During use, the user can match different flavored liquid storage chambers 16 according to the use requirements to meet different needs. The oil storage housing 1 and the atomization component are designed separately, and a new atomization component can also be replaced according to the different liquid storage chambers 16 matched, so as to avoid flavor mixing and affecting the suction experience.

[0067] Specifically, please refer to Figure 9 , the oil guiding component 4 includes at least two coaxially sleeved metal pipe sections 41. A radially protruding limiting boss 42 is provided at the joint of adjacent two metal pipe sections 41, and the limiting part forms an axial limiting fit with the limiting ring groove 43 on the inner wall of the adjacent metal pipe section 41. Here, the combined positioning structure of the limiting boss 42 and the limiting ring groove 43 can lock the telescopic movement of the oil guiding component 4 to achieve precise cooperation with the number of the liquid storage chambers 16.

[0068] In one embodiment, please refer to Figure 7 , the atomization core 3 includes an outer tube 31, an inner tube 32, a first liquid guide 33 and a second liquid guide 34. A plurality of first oil inlet holes 311 are formed in the side wall of the outer tube 31. The inner tube 32 is coaxially sleeved inside the outer tube 31. A plurality of second oil inlet holes 321 are formed in the side wall of the inner tube 32. The first oil inlet holes 311 and the second oil inlet holes 321 are arranged circumferentially in a staggered manner.

[0069] Specifically, six equally spaced first oil inlet holes 311 with a hole diameter of 0.5 mm are provided on the side wall of the outer tube 31. Two cylindrical second oil inlet holes 321 are symmetrically distributed on the side wall of the inner tube 32. The hole diameter of the second oil inlet hole 321 is much larger than the space of the first oil inlet hole 311, and there is a circumferential misalignment angle of about 30°-60° between the second oil inlet hole 321 and the adjacent first oil inlet hole 311. An annular gap of 0.8 mm - 1.2 mm is formed between the inner side walls of the outer tube 31 and the inner tube 32. The first liquid guide 33 is filled in the annular gap, and the second liquid guide 34 is attached to the inner wall of the inner tube 32. The heating element 35 is a heating mesh with a specific pattern, and the heating mesh is wound into a C shape and attached to the inner side wall of the second liquid guide 34 away from the inner tube 32. Here, the atomization core 3 is provided with liquid guides on both the inner and outer sides of the inner tube 32. The liquid guide can be formed by stacking and winding multiple layers of different types of cotton materials. From the outside to the inside, the oil guiding rate of each layer of cotton material decreases in turn, so that the flow rate of the e-liquid decreases from the inside to the outside, effectively reducing the pressure of the e-liquid on the atomization core 3 and avoiding the risk of oil leakage from the atomization core 3.
