Description

Technical Field

[0001] The present invention relates to the technical field of atomizers, and particularly to an atomization device and an electronic atomizer. Background Art

[0002] An electronic cigarette, also known as a virtual cigarette or e-cigarette, has the same appearance as a cigarette, a similar taste to a cigarette, and even many more flavors than ordinary cigarettes. It can also draw out smoke, taste, and sensations like a cigarette. It is mainly used to replace cigarettes. An electronic cigarette is also a non-combustible alternative product to cigarettes. It has some similarities with ordinary cigarettes, such as being able to refresh the mind, satisfy the pleasure of smokers, and meet the usage habits developed over the years. However, it is essentially different from ordinary cigarettes. Electronic cigarettes do not burn, do not contain tar, and do not contain more than 460 chemical substances produced during the combustion of ordinary cigarettes that can cause respiratory and cardiovascular diseases. Thus, the carcinogenic substances in ordinary cigarettes are removed, and it does not cause harm to others from "second-hand smoke" or pollute the environment. For the oil leakage problem of the atomizer of traditional electronic cigarettes, an isolation chamber is usually separately provided at the bottom of the oil cup to allow the e-liquid in the atomization chamber to flow into the isolation chamber, thereby reducing oil leakage.

[0003] However, the above anti-oil leakage structure of traditional atomizers is complex, which increases the processing difficulty of the internal components of the atomizer, thereby increasing the production cost of the atomizer. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an atomization device and an electronic atomizer that can reduce the probability of oil leakage while reducing production costs.

[0005] The purpose of the present invention is achieved by the following technical solutions:

[0017] Before use, the oil guiding hole of the atomization tube is located within the accommodation hole, such that the oil guiding hole is located inside the solid part of the oil cup, thereby separating the oil guiding hole from the oil storage space and reducing the oil leakage rate. When in use, the atomization tube is pushed into the oil cup, causing the oil guiding hole to move out of the accommodation hole, so that the e-liquid can smoothly contact the atomization heating element to form smoke. Therefore, by simply pushing the length of the atomization tube into the oil cup, the on-off state between the atomization tube and the oil storage space can be adjusted, making the anti-oil leakage structure of the atomization device simple.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] The present invention relates to an atomizing device. In one embodiment, the atomizing device includes an oil cup and an atomizing assembly. The oil cup has an air guiding pipe. The air guiding pipe is used to discharge the smoke. The atomizing assembly includes an atomizing tube and an atomizing heating element. The oil cup is provided with a receiving hole. The atomizing tube passes through the receiving hole, the atomizing tube is communicated with the air guiding pipe, a fuel storage space is formed between the atomizing tube and the oil cup, the atomizing heating element is received in the atomizing tube, and the atomizing tube is provided with an oil inlet hole. The atomizing heating element corresponds to the oil inlet hole. The oil inlet hole is located in the receiving hole. Before use, the oil guiding hole of the atomizing tube is located in the receiving hole, so that the oil guiding hole is located inside the entity of the oil cup, thereby separating the oil guiding hole from the fuel storage space and reducing the oil leakage rate. When in use, the atomizing tube is pushed into the oil cup, so that the oil guiding hole moves out of the receiving hole, thereby enabling the e-liquid to smoothly contact the atomizing heating element to form smoke. Therefore, by only pushing the length of the atomizing tube into the oil cup, the on-off state between the atomizing tube and the fuel storage space can be adjusted, so that the anti-oil leakage structure of the atomizing device is simple, while reducing the probability of e-liquid leakage of the atomizing device, the production cost of the atomizing device is reduced.

[0027] Please refer to Figure 1 , which is a schematic structural diagram of the atomizing device according to an embodiment of the present invention.

[0028] The atomizing device 10 according to an embodiment includes an oil cup 100 and an atomizing assembly 200. The oil cup 100 has an air guiding pipe 110. The air guiding pipe 110 is used to discharge the smoke. The atomizing assembly 200 includes an atomizing tube 210 and an atomizing heating element 220. The oil cup 100 is provided with a receiving hole 120. The atomizing tube 210 passes through the receiving hole 120, the atomizing tube 210 is communicated with the air guiding pipe 110, a fuel storage space 300 is formed between the atomizing tube 210 and the oil cup 100, the atomizing heating element 220 is received in the atomizing tube 210, please refer to Figure 2 together, the atomizing tube 210 is provided with an oil inlet hole 212. The atomizing heating element 220 corresponds to the oil inlet hole 212. The oil inlet hole 212 is located in the receiving hole 120.

[0029] In this embodiment, before use, the oil guiding hole of the atomizing tube 210 is located within the accommodating hole 120, such that the oil guiding hole is inside the solid part of the oil cup 100, thereby separating the oil guiding hole from the oil storage space 300 and reducing the oil leakage rate. When in use, the atomizing tube 210 is pushed into the oil cup 100, causing the oil guiding hole to move out of the accommodating hole 120, enabling the e-liquid to smoothly contact the atomizing heating element 220 to form a mist. Therefore, by simply adjusting the length of the atomizing tube 210 inserted into the oil cup 100, the on-off state between the atomizing tube 210 and the oil storage space 300 can be adjusted. This makes the anti-oil-leakage structure of the atomizing device simple, reducing the probability of e-liquid leakage from the atomizing device while lowering the production cost of the atomizing device.

[0030] In one of the embodiments, please refer to Figure 1 , the oil cup 100 includes a cup body 130 and an oil cup base 140. The oil cup base 140 is detachably connected to the cup body 130. The accommodating hole 120 is formed in the oil cup base 140, and the atomizing tube 210 is slidably connected to the oil cup base 140. In this embodiment, the cup body 130, the oil cup base 140, and the atomizing tube 210 form the oil storage space 300, and e-liquid is stored in the oil storage space 300. At this time, the oil inlet hole 212 is located within the accommodating hole 120, and the accommodating hole 120 is formed in the oil cup base 140, causing the oil inlet hole 212 to be embedded within the oil cup base 140, that is, the oil cup base 140 seals the oil inlet hole 212, preventing the e-liquid in the oil storage space 300 from entering the atomizing tube 210 through the oil inlet hole 212. The detachable connection between the oil cup base 140 and the cup body 130 facilitates the removal of the oil cup base 140 from the cup body 130, thereby facilitating the cleaning of the interior of the oil cup 100. In another embodiment, a clamping groove is formed on the inner wall of the cup body 130, and the oil cup base 140 is clamped within the clamping groove, such that the side walls of the clamping groove clamp the oil cup base 140, facilitating the clamping of the oil cup base 140 to the cup body 130.

[0031] Further, please refer to Figure 3, the oil cup 100 further includes a first clamping protrusion 150. The first clamping protrusion 150 is located within the accommodation hole 120. The first clamping protrusion 150 is connected to the oil cup base 140 and also abuts against the atomization tube 210. In this embodiment, the first clamping protrusion 150 is located within the oil cup base 140, and the first clamping protrusion 150 is connected to the inner wall of the accommodation hole 120. The first clamping protrusion 150 forms an uneven structure on the inner wall of the accommodation hole 120, increasing the frictional force of the inner wall of the accommodation hole 120. When the atomization tube 210 is inserted into the accommodation hole 120, the first clamping protrusion 150 abuts against the outer wall of the atomization tube 210, increasing the frictional force between the inner wall of the accommodation hole 120 and the atomization tube 210, facilitating the clamping of the atomization tube 210 within the accommodation hole 120. In another embodiment, the number of the first clamping protrusions 150 is multiple, and the multiple first clamping protrusions 150 are evenly distributed on the inner wall of the accommodation hole 120 in sequence, making the inner wall of the accommodation hole 120 present multiple uneven structures, further increasing the static friction coefficient of the inner wall of the accommodation hole 120, further increasing the frictional force between the inner wall of the accommodation hole 120 and the atomization tube 210, and further facilitating the stable clamping of the atomization tube 210 within the accommodation hole 120.

[0032] Furthermore, please refer to Figure 3 and Figure 4, the oil cup 100 further includes a second clamping protrusion 160, which is located between the cup body 130 and the oil cup base 140, and the second clamping protrusion 160 is connected to the oil cup base 140. In this embodiment, the second clamping protrusion 160 is located inside the cup body 130, and moreover, the second clamping protrusion 160 abuts against the inner wall of the cup body 130, so that the second clamping protrusion 160 is provided between the inner wall of the cup body 130 and the oil cup base 140. The second clamping protrusion 160 is formed on the oil cup base 140, so that the surface of the oil cup base 140 close to the inner wall of the cup body 130 forms an uneven surface structure, thereby increasing the friction coefficient of the surface of the oil cup base 140 close to the inner wall of the cup body 130, and further increasing the frictional force between the oil cup base 140 and the cup body 130. When the oil cup base 140 is installed inside the cup body 130, the oil cup base 140 contacts the inner wall of the cup body 130 through the second clamping protrusion 160, so that the frictional force between the oil cup base 140 and the cup body 130 is increased, so as to reduce the tendency of the oil cup base 140 to separate from the cup body 130 under the influence of gravity, and facilitate the stable clamping of the oil cup base 140 inside the cup body 130. In another embodiment, the number of the second clamping protrusions 160 is multiple, and the multiple second clamping protrusions 160 are sequentially and evenly distributed on the side of the oil cup base 140 facing away from the atomizing tube 210, so that the outer wall of the oil cup base 140 presents a plurality of uneven structures, further increasing the static friction coefficient of the outer wall of the oil cup base 140, further increasing the frictional force between the oil cup base 140 and the cup body 130, and further facilitating the stable clamping of the oil cup base 140 inside the cup body 130, thereby facilitating the stable connection between the oil cup base 140 and the cup body 130.

[0033] Furthermore, please refer to Figure 3 and Figure 4, the oil cup base 140 is provided with a first through hole 142 which communicates with the oil storage space 300, and the first through hole 142 is used for injecting e-liquid into the oil storage space 300. In this embodiment, the first through hole 142 is spaced from the accommodation hole 120, and the first through hole 142 communicates with the oil storage space 300, that is, the first through hole 142 is used to connect the oil storage space 300 with the external environment, and the oil storage space 300 is used to store e-liquid, facilitating timely replenishment of e-liquid into the oil storage space 300 before use. Thus, during transportation and before use, there is no e-liquid in the oil storage space 300, reducing the probability of oil leakage of the atomization device. Just inject e-liquid into the oil storage space 300 through the first through hole 142 before use. Moreover, after the e-liquid in the oil storage space 300 is used up, e-liquid can be replenished into the oil storage space 300 again through the first through hole 142, enabling the atomization device to be reused.

[0034] Further, please refer to Figure 3 , the oil cup base 140 is provided with a second through hole 144 which communicates with the oil storage space 300, and the second through hole 144 is used for discharging the gas in the oil storage space 300. In this embodiment, the injection tube of an external oil injection device extends into the first through hole 142, and e-liquid is injected into the oil storage space 300 through the first through hole 142. As the volume of e-liquid in the oil storage space 300 gradually increases, the pressure in the oil storage space 300 increases, making it difficult for the external oil injection device to continue injecting e-liquid. If the injection pressure is increased, it is easy to cause the internal pressure of the oil cup 100 to be too high and burst. To reduce the damage of the oil cup 100 due to excessive internal pressure, the oil storage space 300 is connected to the external atmosphere through the second through hole 144, so that the pressure in the oil storage space 300 is always maintained at the same atmospheric pressure, facilitating the continuous injection of e-liquid into the oil storage space 300 by the external oil injection device, reducing the probability of excessive pressure in the oil storage space 300, and thus reducing the probability of damage to the oil cup 100 due to excessive internal pressure. Moreover, during the process of injecting e-liquid into the oil storage space 300 by the external oil injection device, the e-liquid squeezes out the air in the oil storage space 300 through the second through hole 144, reducing the volume of air in the oil storage space 300, thereby increasing the volume of e-liquid stored in the oil storage space 300 and improving the proportion of the e-liquid space in the oil storage space 300, facilitating the storage of more e-liquid in the oil storage space 300.

[0035] Even further, please refer to Figure 3, the atomization assembly 200 further includes a first seal 230 and a second seal 240. The first seal 230 is disposed through the first through hole 142, and the second seal 240 is disposed through the second through hole 144. In this embodiment, the first seal 230 corresponds to the first through hole 142, and the first seal 230 is disposed through the first through hole 142, that is, the first seal 230 is used to block the first through hole 142. When there is e-liquid in the e-liquid storage space 300, the first seal 230 seals the first through hole 142, reducing the probability of the e-liquid in the e-liquid storage space 300 leaking out. For example, after the e-liquid is injected into the e-liquid storage space 300 through the first through hole 142, the first seal 230 is embedded in the first through hole 142, so that the first seal 230 blocks the first through hole 142, reducing the probability of the e-liquid in the e-liquid storage space 300 leaking out through the first through hole 142 during use. The second seal 240 corresponds to the second through hole 144, and the second seal 240 is disposed through the second through hole 144, that is, the second seal 240 is used to block the second through hole 144. When there is e-liquid in the e-liquid storage space 300, the second seal 240 seals the second through hole 144, reducing the probability of the e-liquid in the e-liquid storage space 300 leaking out. For example, after the e-liquid completely discharges the air in the e-liquid storage space 300, the second seal 240 is embedded in the second through hole 144, so that the second seal 240 blocks the second through hole 144, reducing the probability of the e-liquid in the e-liquid storage space 300 leaking out through the second through hole 144 during use. In this way, after the e-liquid is injected into the e-liquid storage space 300 through the first through hole 142, the first seal 230 is embedded in the first through hole 142, so that the first seal 230 blocks the first through hole 142, and the second seal 240 is embedded in the second through hole 144, so that the second seal 240 blocks the second through hole 144, to reduce the probability of oil leakage of the atomization device.

[0036] Further, please refer to Figure 4, the first seal 230 has an installation inclined surface 232, and the installation inclined surface 232 is inclined in a direction away from the atomization tube 210. In this embodiment, the installation inclined surface 232 has an inclination angle, and an included angle is formed between the obtained inclined surface and the inner wall of the cup body 130. In a direction parallel to the installation direction of the first seal 230, the distance between the installation inclined surface 232 and the inner wall of the cup body 130 gradually increases, so that the diameter of the end of the first seal 230 close to the oil storage space 300 is smaller than the diameter of the end of the first seal 230 far from the oil storage space 300, that is, the diameter of the end of the first seal 230 close to the oil storage space 300 is smaller than the aperture of the first through hole 142. In this way, when the first seal 230 is embedded in the first through hole 142, it is convenient for the installation inclined surface 232 to extend into the first through hole 142. Moreover, when the inclined surface of the installation inclined surface 232 contacts the oil cup base 140, the inclination angle of the installation inclined surface 232 facilitates the sliding of the oil cup base 140 on the installation inclined surface 232, and further facilitates the installation of the first seal 230 in the first through hole 142. In another embodiment, the second seal also has an installation inclined surface, which is convenient for the second seal to be installed into the second through hole.

[0037] In one embodiment, please refer to Figure 3, the atomization assembly 200 further includes an intake push tube 250. The intake push tube 250 is connected to the atomization tube 210. A part of the intake push tube 250 is located within the accommodation hole 120, and another part of the intake push tube 250 is located outside the oil cup 100. In this embodiment, the intake push tube 250 serves as an extension part of the atomization tube 210. The part of the intake push tube 250 located outside the oil cup 100 is used to push the atomization tube 210, so that the atomization tube 210 moves towards the oil storage space 300, thereby enabling the intake push tube 250 to be completely embedded within the oil cup 100, facilitating the pushing of the oil inlet hole 212 on the atomization tube 210 to communicate with the oil storage space 300, and thus facilitating the adjustment of the position of the atomization tube 210 within the accommodation hole 120. In this way, before the atomization device is used, a part of the intake push tube 250 is located outside the oil cup 100, and when the atomization device is in use, only by pushing the intake push tube 250 towards the oil storage space 300, it is convenient to increase the length of the atomization tube 210 extending into the oil storage space 300, thereby facilitating the adjustment of the position of the oil inlet hole 212 of the atomization tube 210 within the oil cup 100, and further facilitating the communication of the oil inlet hole 212 of the atomization tube 210 with the oil storage space 300, enabling the e-liquid in the oil storage space 300 and the atomization heating element 220 in the atomization tube 210 to achieve wet-dry separation. Moreover, since only the position of the intake push tube 250 within the oil cup 100 needs to be adjusted, the communication state between the oil inlet hole 212 of the atomization tube 210 and the oil storage space 300 can be adjusted, making the anti-leakage structure of the atomization device simple. While reducing the probability of e-liquid leakage from the atomization device, the production cost of the atomization device is reduced.

[0038] It can be understood that the intake push tube 250 serves as a position adjustment component of the atomization tube 210. The intake push tube 250 is used to adjust the position of the atomization tube 210 within the accommodation hole 120, facilitating the adjustment of the position of the oil inlet hole 212 of the atomization tube 210. However, when the part of the intake push tube 250 located outside the oil cup 100 is completely embedded within the accommodation hole 120, it is easy for the end of the intake push tube 250 away from the atomization tube 210 to be flush with the oil cup base 140. Even if the intake push tube 250 extends excessively into the accommodation hole 120, it will cause the inability to grasp the intake push tube 250, resulting in the inability to extract the intake push tube 250 from the oil cup 100, causing the oil storage space 300 to be in long-term communication with the external space through the atomization tube 210 and the intake push tube 250. Thus, when the atomization device is not in use and there is still e-liquid in the oil storage space 300, the e-liquid leaks through the atomization tube 210 and the intake push tube 250.

[0039] For the convenience of grasping the intake push tube 250, please refer to Figure 3 , the intake push tube 250 includes a first push tube 252 and a second push tube 254. The first push tube 252 communicates with the second push tube 254. The first push tube 252 is connected to the atomizing tube 210. At least a part of the first push tube 252 is located in the accommodating hole 120. The second push tube 254 is located outside the oil cup 100, and the diameter of the second push tube 254 is smaller than that of the first push tube 252. In this embodiment, the first push tube 252 is connected to the second push tube 254, and the internal space of the first push tube 252 is connected to the internal space of the second push tube 254, which is convenient for air to be introduced into the accommodating hole 120, so as to guide the smoke generated by the atomizing heating element 220 of the atomizing tube 210 to the air guiding pipe 110. The second push tube 254 is located outside the oil cup 100, that is, the second push tube 254 is located outside the accommodating hole 120, and the second push tube 254 is located at one end of the first push tube 252 away from the oil storage space 300, so that the second push tube 254 extends out of the oil cup 100, which is convenient for pushing the atomizing tube 210. Moreover, the diameter of the second push tube 254 is smaller than that of the first push tube 252. When the intake push tube 250 is completely or even overly embedded in the accommodating hole 120, the diameter of the second push tube 254 is smaller than the diameter of the accommodating hole 120, so that a gap is formed between the second push tube 254 and the inner wall of the accommodating hole 120, which is convenient for grasping the second push tube 254 that is completely or even overly embedded in the accommodating hole 120, so as to facilitate the extraction of the intake push tube 250 from the accommodating hole 120, and further facilitate the grasping of the intake push tube 250, so that by pushing and pulling the intake push tube 250, the length of the atomizing tube 210 extending into the oil storage space 300 can be adjusted, thereby realizing the adjustment of the on-off state between the oil inlet hole 212 of the atomizing tube 210 and the oil storage space 300.

[0040] When the oil inlet hole 212 of the atomizing tube 210 communicates with the oil storage space 300 in the state where the second push tube 254 communicates with the first push tube 252, the e-liquid enters the atomizing tube 210 through the oil inlet hole 212, and it is easy for the e-liquid to enter the second push tube 254 through the first push tube 252 under the action of gravity, and then leak out to the outside, resulting in a reduction in the anti-oil leakage performance of the atomizing device. In order to further reduce the oil leakage probability of the atomizing device, please refer to Figure 3, the first push tube 252 has a first air inlet hole 2522, the second push tube 254 has a second air inlet hole 2542, both the first air inlet hole 2522 and the second air inlet hole 2542 communicate with the internal space of the atomizing tube 210, an included angle is formed between the central axis of the first air inlet hole 2522 and the central axis of the second air inlet hole 2542, and the second push tube 254 is further provided with an isolation groove 2544 communicating with the second air inlet hole 2542, and the opening of the isolation groove 2544 faces the first push tube 252. In this embodiment, the central axis of the first air inlet hole 2522 and the central axis of the second air inlet hole 2542 are in a crossed state, so that the first air inlet hole 2522 and the second air inlet hole 2542 are in a staggered state, thereby making the air inlet flow path a tortuous path rather than a straight-through air inlet flow path, and further making the bottom of the second push tube 254 correspond to the first air inlet hole 2522, that is, at least part of the projection of the bottom of the second push tube 254 on the first push tube 252 is located in the first air inlet hole 2522. Moreover, the isolation groove 2544 is located at the bottom of the second push tube 254, so that an isolation space is formed at the bottom of the second push tube 254, and the opening of the isolation groove 2544 faces the first push tube 252, thereby making the isolation groove 2544 correspond to the first air inlet hole 2522, facilitating the collection of the e-liquid leaking through the atomizing tube 210 and the first push tube 252 in the isolation groove 2544, and further reducing the e-liquid leakage probability of the atomizing device.

[0041] Moreover, the second push tube 254 is a semi-closed conduit, that is, one end of the second push tube 254 is closed, the other end of the second push tube 254 communicates with the first push tube 252, and the closed end of the second push tube 254 serves as the bottom of the second push tube 254 to facilitate the formation of the isolation groove 2544, and the second air inlet hole 2542 is opened on the side wall of the second push tube 254. Due to the simple structures of the first push tube 252 and the second push tube 254, the e-liquid leakage prevention structure of the atomizing device is simple, while reducing the e-liquid leakage probability of the atomizing device, the production cost of the atomizing device is further reduced.

[0042] In another embodiment, the central axis of the first air inlet hole 2522 is parallel to the central axis of the accommodation hole 120, and the central axis of the first air inlet hole 2522 is perpendicular to the central axis of the second air inlet hole 2542, so that the air inlet channel formed by the first air inlet hole 2522 and the second air inlet hole 2542 is increased, facilitating the sealing of more e-liquid in the isolation groove 2544, and further reducing the e-liquid leakage probability of the atomizing device.

[0043] In addition, the opening of the second air inlet hole 2542 faces the inner wall of the accommodating hole 120. When the second push tube 254 is fully or even excessively embedded in the accommodating hole 120, the second air inlet hole 2542 can serve as a grasping position, facilitating the grasping device to extend into the second air inlet hole 2542 through the gap between the second push tube 254 and the inner wall of the accommodating hole 120, thereby facilitating the extraction of the second push tube 254 from the accommodating hole 120.

[0044] Furthermore, please refer to Figure 3, the atomizing heating element 220 includes an atomizing core 222 and a heating wire 224. The atomizing core 222 is disposed within the atomizing tube 210. The atomizing core 222 corresponds to the oil inlet hole 212. The heating wire 224 is connected to the atomizing core 222. The atomizing assembly 200 further includes an insulating plug 260. The insulating plug 260 is sleeved on the air intake push tube 250. Both the air intake push tube 250 and the atomizing tube 210 have electrical conductivity. The first end of the heating wire 224 is located between the air intake push tube 250 and the insulating plug 260, and the first end of the heating wire 224 is used for electrically connecting to the positive electrode of the battery rod. The second end of the heating wire 224 is located between the atomizing tube 210 and the insulating plug 260, and the second end of the heating wire 224 is used for electrically connecting to the negative electrode of the battery rod. In this embodiment, both ends of the heating wire 224 are connected to the battery rod through the air intake push tube 250 and the atomizing tube 210 respectively. The insulating plug 260 insulates the air intake push tube 250 from the atomizing tube 210, avoiding the short circuit between the positive and negative electrodes of the battery rod. Moreover, by disposing the air intake push tube 250 and the atomizing tube 210 having electrical conductivity within the accommodation hole 120, and relying on the existing structure, it is convenient to electrically conduct the heating wire 224 to the external battery rod without adding other electrode posts to achieve the electrical conduction between the heating wire 224 and the battery rod, further reducing the production cost of the atomizing device. In this embodiment, in order to facilitate connecting the second end of the heating wire 224 to the negative electrode of the external battery rod after the atomizing tube 210 is completely embedded in the accommodation hole 120, the atomizing assembly 200 further includes a conductive connection sleeve 270 and a conductive oil cup bottom cover 280. The conductive connection sleeve 270 is sleeved on the outer wall of the atomizing tube 210. The conductive oil cup bottom cover 280 is located outside the oil cup 100. The conductive oil cup bottom cover 280 is connected to the conductive connection sleeve 270. The conductive oil cup bottom cover 280 is also snap-connected to the oil cup 100. The conductive oil cup bottom cover 280 is used for electrically connecting to the negative electrode of the external battery rod. In this way, the second end of the heating wire 224 is electrically connected to the conductive connection sleeve 270 through the atomizing tube 210, and the conductive connection sleeve 270 is electrically connected to the negative electrode of the external battery rod through the conductive oil cup bottom cover 280, facilitating the connection of the second end of the heating wire 224 to the negative electrode of the external battery rod.

[0045] In another embodiment, the conductive connecting sleeve 270 is sleeved on the outer wall of the atomizing tube 210, that is, the conductive connecting sleeve 270 is located between the atomizing tube 210 and the inner wall of the accommodating hole 120. The conductive connecting sleeve 270 fills the gap between the atomizing tube 210 and the inner wall of the accommodating hole 120, improving the sealing performance of the accommodating hole 120. Moreover, the conductive connecting sleeve 270 abuts against the outer wall of the atomizing tube 210 and the inner wall of the accommodating hole 120 respectively, increasing the squeezing force of the oil cup base 140 clamping the atomizing tube 210, and further improving the installation stability of the atomizing tube 210 in the accommodating hole 120. In addition, the conductive oil cup bottom cover 280 is snap-connected to the oil cup 100. For example, the conductive oil cup bottom cover 280 is connected to the cup body 130 and the oil cup base 140 respectively. The conductive oil cup bottom cover 280 blocks the first through hole 142 and the second through hole 144, reducing the probability of the e-liquid in the oil storage space 300 leaking out through the first through hole 142 and the second through hole 144, and further reducing the probability of e-liquid leakage of the atomizing device.

[0046] The present application also provides an electronic atomizer, including the atomizing device described in any of the above embodiments. In this embodiment, the atomizing device includes an oil cup and an atomizing assembly. The oil cup has an air guiding pipeline for guiding out the smoke. The atomizing assembly includes an atomizing tube and an atomizing heating element. The oil cup is provided with an accommodating hole. The atomizing tube passes through the accommodating hole, and the atomizing tube is communicated with the air guiding pipeline. A storage space for e-liquid is formed between the atomizing tube and the oil cup. The atomizing heating element is received in the atomizing tube, and an oil inlet hole is provided in the atomizing tube. The atomizing heating element corresponds to the oil inlet hole. The oil inlet hole is located in the accommodating hole. Before use, the oil guiding hole of the atomizing tube is located in the accommodating hole, so that the oil guiding hole is located inside the solid of the oil cup, thereby separating the oil guiding hole from the oil storage space and reducing the oil leakage rate. When in use, the atomizing tube is pushed into the oil cup, so that the oil guiding hole moves out of the accommodating hole, so that the e-liquid can smoothly contact the atomizing heating element to form smoke. Therefore, by simply pushing the length of the atomizing tube extending into the oil cup, the on-off state between the atomizing tube and the oil storage space can be adjusted, making the anti-oil leakage structure of the atomizing device simple. While reducing the probability of e-liquid leakage of the atomizing device, the production cost of the atomizing device is reduced.
