[0029] Example:

[0030] like Figure 1-5 As shown, in this embodiment, the electronic atomizing device includes: an oil cup 1, an atomizing component 2, and a battery rod 3; wherein, the oil cup 1 includes an integrally formed inner tube 11 and an outer tube 12, with a liquid storage chamber 13 formed between the inner tube 11 and the outer tube 12, and the inner tube 11 also forms a venting channel 14 communicating with the outside; the atomizing component 2 includes an atomizing core 22 and a sealing member 21, the sealing member 21 being sleeved on the outside of the atomizing core 22, and the sealing member 21 including an inner end portion 211 and an outer end portion connected to the inner end portion 211. 212, the inner end 211 abuts against the bottom end of the inner tube 11, the outer end 212 abuts against the bottom end of the outer tube 12, and the sealing member 21 is also provided with a liquid outlet 216 between the outer end 212 and the inner end 211, which connects the liquid storage chamber 13 and the atomizing core 22; the battery rod 3 includes a housing 31, a battery assembly 33 fixed in the housing 31 and a bracket 32; the bracket 32 ​​abuts against the side of the outer end 212 away from the outer tube 12, and the battery assembly 33 is electrically connected to the atomizing core 22 through the electrode 331.

[0031] Specifically, the sealing element 21 in this embodiment can be a silicone part. The oil cup 1 in this embodiment is an integrally formed structure of inner tube 11 and outer tube 12. The inner tube 11 and the inner end 211 of the sealing element 21 are sealed by abutment, and the outer tube 12 and the outer end 212 of the sealing element 21 are sealed by abutment. That is, the inner and outer annular end faces of the sealing element 21 are press-fitted with the inner and outer annular end faces of the oil cup 1. Inside the housing 31, the bracket 32 ​​abuts against the sealing element 21 from the bottom side upward, so that the outer end 212 of the sealing element 21 can be clamped and fixed by the outer tube 12 and the bracket 32. This simplifies the device connection structure, reduces the cost of processing and assembling parts, and shortens the oil guiding path, which is beneficial to improving atomization efficiency.

[0032] In this embodiment, an atomizing channel 23 is formed between the atomizing core 22 and the support 32, and a transition cavity 218 is formed on the sealing member 21, connecting the atomizing channel 23 to the air passage 14. Specifically, the main body of the atomizing core 22 is embedded in the sealing member 21, and the core heating component of the atomizing core can be horizontally placed on the bottom side of the sealing member 21, forming the atomizing channel 23 with the support 32, which is beneficial for absorbing the atomizing liquid (e-liquid) and thus increasing the amount of atomized vapor. The aerosol generated by the atomizing core 22 heating and atomizing the e-liquid mixes with the atmosphere in the atomizing channel 23 and can be discharged outside the electronic atomizing device along the transition cavity 218 and the air passage 14 for the user to enjoy.

[0033] In this embodiment, a diffuser 5 with air guide holes 51 on its wall is also included. The diffuser 5 is located within the atomization channel 23 and fixed to the top of the bracket 32. The bracket 32 ​​has an air inlet 321 communicating with the diffuser 5. The diffuser 5 can disperse the airflow and guide it to the heating area of ​​the atomizing core 22, thereby improving the atomization effect. Furthermore, in some specific embodiments, multiple air guide holes 51 are provided. The multiple air guide holes 51 are evenly and spaced on the outer periphery of the diffuser 5 at the end away from the bracket 32, thereby dispersing and evenly guiding the airflow to the heating area of ​​the atomizing core 22.

[0034] In this embodiment, the atomizing core 22 includes a liquid guide 221 and a heating element 222; the sealing member 21 is provided with a receiving cavity 217 on the side away from the liquid storage cavity 13 and an inner extension 215 connected to the outlet of the receiving cavity 217 and extending toward the receiving cavity 217; the liquid outlet 216 communicates with the receiving cavity 217; the liquid guide 221 is embedded in the receiving cavity 217; part of the heating element 222 is sandwiched between the liquid guide 221 and the inner extension 215; the electrode 331 is fixed to the bracket 32 ​​and connected to the side of the heating element 222 away from the liquid guide 221.

[0035] Specifically, in this embodiment, the battery assembly 33 can supply power to the heating element 222 via the electrode 331. The liquid guide 221 in this embodiment can be a ceramic body; the heating element 222 in this embodiment can be a metal sheet or a heating trace formed on the surface of the liquid guide 221 by coating or printing conductive paste. One side of the heating element 222 is fixedly connected to and supported by the electrode 331, and the other side abuts against the liquid guide 221 at the outlet of the receiving groove. The atomizing liquid stored in the liquid storage chamber 13 can enter the liquid guide 221 along the lower liquid hole 216, and then reach the heating element 222. After the electrode 331 and the heating element 222 are energized, the heating element 222 can be heated, thereby causing the atomizing liquid to atomize and form an aerosol. This arrangement, with the atomizing core 22 embedded and the heating element 222 horizontally positioned, absorbs more e-liquid, has a larger heating area, and produces a larger amount of atomized vapor.

[0036] In this embodiment, the sealing member 21 includes a first enclosing wall 213 connected to the inner end 211 on the side opposite to the oil cup 1 and a second enclosing wall 214 connected to the outer end 212 on the side opposite to the oil cup 1. The first enclosing wall 213 and the second enclosing wall 214 are spaced apart from each other, and the inner side of the first enclosing wall 213 encloses to form a transition cavity 218. The bottom side of the inner end 211 of the sealing member 21, the outer side of the first enclosing wall 213, the inner side of the second enclosing wall 214, and the inner extension 215 together enclose to form a receiving cavity 217. The bracket 32 ​​abuts against the outer side of the second enclosing wall 214 and the bottom side of the outer end 212, respectively. With the sealing member 21 arranged in this way, the liquid guide 221 and the heating element 222 can be stably embedded in the receiving groove. At the same time, the upper end of the bracket 32 ​​abuts against the outer periphery and the bottom side of the sealing member 21, thereby providing a stable support for the sealing member 21.

[0037] Furthermore, in this embodiment, the wall of the accommodating cavity 217 is also provided with a return air groove 2171. That is, the inner side wall of the second enclosing wall 214 is provided with a return air groove 2171. The liquid guide 221 and the return air groove 2171 enclose each other to form an auxiliary liquid-feeding channel. The auxiliary liquid-feeding channel can achieve air exchange with the outside through the pores in the ceramic body. One or more return air grooves 2171 can be provided. The auxiliary liquid-feeding channel formed by the return air grooves 2171 can assist in the oil feeding, realize a dual oil supply path, and effectively improve the atomization volume. In this embodiment, multiple liquid-feeding holes 216 are provided. The multiple liquid-feeding holes 216 are spaced apart and distributed around the bottom side of the liquid storage cavity 13; thereby increasing the oil feeding volume and improving the atomization effect. For example, four liquid-feeding holes 216 can be provided.

[0038] In this embodiment, a fastening member 4 is also included, which is fixed to the inner wall of the housing 31 near the oil cup 1. A limiting groove 121 is also provided on the outer periphery of the bottom end of the outer tube 12. The side of the fastening member 4 away from the housing 31 abuts against the limiting groove 121. The end of the fastening member 4 away from the limiting groove 121 also has a first fastening part 41 extending inward. The outer periphery of the bracket 32 ​​has a second fastening part 322 corresponding to the first fastening part 41. The first fastening part 41 and the second fastening part 322 are fastened and fixed together.

[0039] Specifically, the fastener 4 and the housing 31 can be fixed by riveting, which provides a good fixing effect. The fastener 4 includes a connecting wall and an extension portion connected to the top of the connecting wall and extending outward; the connecting wall is clamped between the longitudinal wall surface of the limiting groove 121 and the housing 31, and is riveted to the housing 31; the extension portion abuts between the top of the housing 31 and the transverse wall surface of the limiting groove 121. The first fastening part 41 is connected to the end of the connecting wall away from the extension portion. Through the mutual cooperation between the first fastening part 41 and the second fastening part 322, the assembly stability of the bracket 32 ​​can be fully ensured. In this embodiment, the fastener 4 is set in this way to fix the oil cup 1, the housing 31, and the bracket 32, which provides a good fixing effect and is easy to assemble. For example, during the assembly process, after the fastening part 4 is fixed to the housing 31, the oil cup 1 with the atomizing component 2 and the bracket 32 ​​installed is inserted along the opening end of the housing 31. When the device moves to the point where the second fastening part 322 and the first fastening part 41 fasten each other, a stable assembly between the housing 31 and the bracket 32 ​​can be achieved.

[0040] In this embodiment, the oil cup 1 is a transparent component. For example, the oil cup 1 can be a glass component, or at least the outer tube 12 of the oil cup 1 can be a glass component, thereby facilitating direct observation of the remaining amount of atomized liquid in the storage chamber 13 from the outside of the electronic atomizing device.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
