Description

Technical Field

[0001] The present invention relates to the field of electronic cigarettes. Background Art

[0002] E-cigarettes are electronic products that mimic cigarettes. Like traditional cigarettes, they produce gases containing nicotine, tar, and other substances, allowing users to experience a sensation very similar to that of traditional cigarettes. The smoke produced by e-cigarettes is generated by atomizing a liquid containing tobacco-like substances. The atomizer inside the e-cigarette, through heating and other methods, converts the nicotine-containing liquid into a vapor that is then inhaled by the user. E-cigarettes are often used as a cigarette substitute or as a transitional product for users trying to quit smoking. Compared to cigarettes, e-cigarettes offer the advantages of controllable smoke composition, less smoke, and greater safety, as they are less likely to cause fires due to littering of cigarette butts. By controlling the composition and volume of smoke, they minimize the harmful effects of smoking and reduce the amount of secondhand smoke smoked by smokers, making them highly popular with consumers.

[0003] However, the atomization core components of traditional electronic cigarettes usually have an air flow channel running through the axis of the core body, and a heating component is installed in the air flow channel. The air path causes the oil to easily flow out of the air flow channel to the outside, causing contamination of external objects. At the same time, the leaked smoke liquid can easily cover the power supply device of the electronic cigarette, causing it to gradually penetrate into the power supply device and cause a safety hazard of short circuit of the power supply device.

[0046] Reference Figures 1 to 10 The present invention provides an electronic cigarette 1000, which includes an atomization device 100 and a power supply device 200. The atomization device 100 includes a base 30, a shell 50 and an atomization core component 10. The base 30 is provided with an installation cavity 31 for installing the atomization core component 10; the shell 50 is detachably mounted on the base 30, and is formed together with the base 30 to form an air guide cavity 40, and the shell 50 is provided with a suction port 51 connected to the air guide cavity 40 for the user to inhale. The atomization core component 10 includes: a core seat 11 and a heating component 12. The core seat 11 is provided with an atomization groove 111 and an air flow channel 112, and one end of the air flow channel 112 forms an air inlet 113 connected to the outside world on the surface of the core seat 11, and the other end forms an air hole 114 on the side groove wall of the atomization groove 111. The heating component 12 is mounted on the core seat 11 and is partially located in the atomization groove 111. The external air flow passes through the air inlet 113, the air flow channel 112, the air hole 114, and the atomization groove 111 in sequence and then flows out through the notch of the atomization groove 111.

[0047] The present invention provides an atomization groove 111 on the core seat 11, and then mounts a heating component 12 on the core seat 11 and partially locates it in the atomization groove 111, so that the heating component 12 is located in a larger air cavity. This prevents the atomization core part 10 of the traditional electronic cigarette 1000 from wrapping the heating component 12, resulting in more concentrated heat and easy heating of the atomization device 100 of the electronic cigarette 1000. At the same time, an air flow passage 112 is provided in the core seat 11, and the air flow passage 112 is opened on the side wall of the atomization groove 111 to form an air hole 114. When the user inhales, the external air flow passes through the air inlet 113, the air flow passage 112, and the air hole 114 and flows into the atomization groove 111, and mixes with the smoke generated by the heating component 12 heating and atomizing the smoke liquid, and then flows out from the notch of the atomization groove 111, ensuring the provision of a stable working airflow. At the same time, the air flow passage 112 is provided in the core seat 11. Compared with the traditional atomization device 100 that only has an air inlet at the bottom, this solution effectively reduces heat conduction and further prevents heat concentration. At the same time, the air outlet is provided on the side wall of the core seat 11, which effectively prevents the smoke liquid from flowing out of the air outlet.

[0048] Specifically, if Figure 1 As shown, in an embodiment of the present invention, the two side walls of the atomizing groove 111 are provided with the air holes 114, and the air holes 114 are located below the heating component 12 in the direction of gravity, so that the air flow out of the air holes 114 passes through the heating component 12 and then flows out through the notch of the atomizing groove 111. Here, in this embodiment, the air holes 114 are located below the heating component 12 in the direction of gravity, so there is a certain height difference between the air holes 114 and the heating component 12. When the user inhales, the air flows from the air holes 114 into the atomizing groove 111, mixes and atomizes to produce smoke, and then flows out from the notch. The taste is relatively mellow. It effectively avoids the situation where the air holes 114 are flush with the heating component 12. When the user inhales, part of the air flow out of the air holes 114 does not mix with the smoke atomized by the heating component 12 and is directly drawn into the mouth, resulting in a poor taste.

[0049] Specifically, if Figure 1As shown, in order to better mix the airflow with the smoke generated by the atomization of the heating component 12, in an embodiment of the present invention, the hole wall of the air hole 114 is designed to be inclined to form a guide surface 1141, and the extension line 1141' of the guide surface 1141 from the side exposed from the atomization groove 111 intersects with the heating component 12. So as to guide the airflow to the heating component 12. Here, the air hole 114 is located below the heating component 12, so that the hole wall of the lower end of the air hole 114 gradually decreases from the side adjacent to the atomization groove 111 to the side away from the atomization groove 111, and the extension line 1141' of the hole wall of the lower end of the air hole 114 extending from the atomization groove 111 is directly facing the heating component 12. By guiding the airflow, it is further ensured that the airflow flows from the air hole 114 into the atomization groove 111, mixes and atomizes to produce smoke, and then flows out from the groove. At the same time, by designing the air holes 114 to be inclined, it is effectively prevented that smoke liquid is deposited in the air holes 114, which would make cleaning inconvenient.

[0050] Specifically, if Figure 1 Combined with Figure 8 and Figure 9 In the embodiment of the present invention, the heating assembly 12 includes a heating element 121 and an oil-absorbing element 122. The heating element 121 partially wraps around the outer circumference of the oil-absorbing element 122. When the heating assembly 12 is mounted on the core base 11, an extension line 1141' of the guide surface 1141 exposed on one side of the atomizer slot 111 intersects with the heating element 121 to direct airflow toward the heating element 121. During operation, the heating element 121 generates heat driven by an electric current, instantly vaporizing the tobacco liquid absorbed by the oil-absorbing element 122 to produce aerosol. When a user inhales, ambient air flows through the air inlet 113 into the airflow passage 112, then passes through the air holes 114 and the guide surface 1141 and is directed to the surface of the heating element 121, where it mixes with the generated aerosol for the user to inhale. Simultaneously, the heating element 121 is cooled, preventing damage to the aerosol guide element caused by slow cooling of the heating element 121 and continuous inhalation over a short period of time.

[0051] Specifically, if Figure 1 , and combined with Figure 8 or Figure 8As shown, in this embodiment of the present invention, the heating element 121 is hollow, and the oil-absorbing element 122 includes an oil-absorbing portion and a heat-receiving portion 1221. When the heating assembly 12 is installed in the core base 11, the extension line 1141' of the guide surface 1141 exposed on one side of the atomizer tank 111 intersects with the outer peripheral surface of the heating element 121. The heat-receiving portion 1221 fills the hollow portion of the heating element 121, and the oil-absorbing portion extends from the end surface of the heating element 121 to absorb the e-liquid. In this embodiment, the oil-absorbing element 122 is made of cotton material with oil-storage properties. The cotton material of the heat-receiving portion 1221 is densely packed to prevent significant deformation after absorbing the e-liquid. The oil-absorbing portion is relatively loose, thereby facilitating the absorption of more e-liquid and improving e-liquid conductivity. Furthermore, by intersecting the extension line 1141' of the guide surface 1141 with the outer peripheral surface of the heating element 121, the heat-receiving portion 1221 of the oil-absorbing element 122 is enclosed by the heating element 121. The oil-absorbing portion extends from the end surface of the heating element 121 to the outside and is accommodated in the atomization tank 111, thereby absorbing the smoke liquid and transferring the smoke liquid to the heat-receiving portion 1221. At this time, when the user inhales, the airflow flowing out of the air hole 114 is guided by the guide surface 1141 to the outer peripheral surface of the heating element 121, thereby preventing the airflow from impacting the oil-absorbing portion extending from the end surface of the heating element 121. This would cause the smoke liquid absorbed by the cotton wool in the oil-absorbing portion to be separated from the oil-absorbing portion by the airflow and directly inhaled into the user's mouth.

[0052] Specifically, if Figure 4 As shown, in the embodiment of the present invention, the width of the opening of the air hole 114 in the atomizing groove 111 is smaller than the length of the heating element 121 in the axial direction, thereby further preventing the airflow flowing out of the air hole 114 from causing airflow impact on the oil suction part.

[0053] Specifically, if Figure 1As shown, in an embodiment of the present invention, the number of the air holes 114 is two, and the two air holes 114 are symmetrically arranged on the two side walls of the atomizing tank 111 and are arranged toward the outer peripheral surface of the heating element 121. At the same time, each of the air holes 114 is correspondingly provided with an air flow passage 112, that is, the two air flow passages 112 are relatively located on both sides of the heating element 121. When the heating element 121 generates heat, the heating element 121 generates a higher temperature in the circumferential direction, while the end faces at both ends of the heating element 121 are blocked by the oil absorption portion, so the temperature is lower. Therefore, the temperature of the two side walls of the atomizing tank 111 facing the circumferential direction of the heating element 121 is higher, and in this embodiment, the two air flow passages 112 provided on both sides of the heating element 121 in the core seat 11 effectively form a temperature-isolating cavity to prevent the temperature from being conducted to the outside of the base 30, resulting in a higher temperature on the outer surface of the atomizing device 100. At the same time, by providing air holes 114 on both sides of the heating element 121, it is effectively prevented that the temperature on one side of the heating element 121 is higher due to unilateral airflow, resulting in uneven heating.

[0054] Specifically, if Figure 8 As shown, in this embodiment of the present invention, the heating element 121 is a heating tube, and a plurality of through-holes are formed in the tube wall of the heating tube to form a plurality of oil storage gaps. These oil storage gaps increase the direct contact area between the heating element 121 and the smoke liquid, thereby increasing the instantaneous smoke concentration and enhancing the inhalation sensation at the mouth 51. At the same time, the generated smoke can flow out of each oil storage gap, preventing the phenomenon of the heated portion 1221 from deforming due to the instantaneous high air pressure in the hollow part of the heating element 121.

[0055] It is understood that in actual application, the heating element 121 is not limited to the above embodiment, in which a plurality of through holes are opened in the wall of the heating tube to form the oil storage gap. For example, in other embodiments of the present invention, the heating element 121 can also be designed as a mesh structure, the heating mesh wraps the oil absorption part, and the mesh of the heating mesh forms a plurality of oil guide gaps; for example, Figure 9 As shown, the heating element 121 is a heating wire, the heating wire is wound around the oil guide portion 1222, and an oil storage gap is formed between the parallel heating wires. All of these belong to the protection scope of the present invention and will not be described in detail here.

[0056] Reference Figure 4 The present invention also provides an atomization device 100 of an electronic cigarette 1000, which includes a housing 50, a base 30 and an atomization core component 10. The specific structure of the atomization core component 10 refers to the above embodiment. Since the atomization device 100 of the electronic cigarette 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0057] Specifically, if Figure 4 As shown, in this embodiment of the present invention, the base 30 and the shell 50 enclose an air guide cavity 40; the shell 50 is provided with a suction port 51 connected to the air guide cavity 40 for the user to inhale; the suction port 51 is directly opposite to the atomization groove 111 provided on the core base 11, and the user can drip smoke liquid from the suction port 51 into the atomization groove 111 so that the smoke liquid is absorbed by the oil absorption part. The base 30 is provided with a mounting cavity 31 for mounting the atomizer core component 10. The atomizer core component 10 is interference-fitted into the mounting cavity 31. The interference-fitting method effectively facilitates the user to install. The air inlet 113 is provided on the side wall of the core seat 11. The shell 50 is correspondingly provided with a first air inlet. The core seat 11 is provided with a second air inlet 32 ​​to communicate with the air path of the air inlet 113. At the same time, in this embodiment, the shell 50 is rotatably connected to the base 30. The shell 50 can be rotated to adjust the conduction area between the first air inlet and the second air inlet 32, thereby adjusting the airflow size.

[0058] Specifically, if Figure 1 、 Figure 2 or Figure 4 As shown, in this embodiment of the present invention, to further prevent the smoke liquid from flowing out of the first air inlet of the housing 50, when the core seat 11 is installed on the base 30, a gap is formed between the bottom surface of the core seat 11 and the bottom cavity wall of the installation cavity 31 to form an oil collection chamber 20. The bottom surface of the atomizer seat is also provided with an oil drain hole 115 connected to the air flow passage 112, and the oil drain hole 115 is provided between the air path of the air inlet hole 113 and the air passage 114. If the water and oil content of the smoke liquid adsorbed by the oil guide is unbalanced, resulting in oil explosion during heating, or if a large amount of smoke liquid flows into the atomizer tank 111 in a short period of time, causing the smoke liquid to flow into the air flow passage 112 from the air passage 114, the smoke liquid can flow out through the oil drain hole 115, effectively preventing the smoke liquid from flowing to the air inlet hole 113 and then out through the first air inlet. At the same time, the oil leakage hole 115 is opened on the inner wall of the air path below the gravity direction, and the width of the oil leakage hole 115 is consistent with the width of the corresponding surface of the air path. When the smoke liquid in the air passage 112 flows under the action of gravity, it will inevitably pass through the oil leakage hole 115, and then flow out from the oil leakage hole 115 into the oil collecting chamber 20, thereby effectively preventing the smoke liquid from flowing out of the air inlet hole 113 and the first air inlet.

[0059] At the same time, because the core seat 11 is inserted into the base 30 by interference, in this embodiment, the atomizer seat is connected to the oil collecting chamber 20 and the air flow channel 112 by providing an oil drain hole 115. When the core seat 11 is pressed into the installation cavity 31 by interference, the air flow in the installation cavity 31 can pass through the oil drain hole 115 and the air flow channel 112 and then be discharged to the outside through the air hole 114, effectively preventing the phenomenon of holding the air during installation and disassembly, which makes it difficult to press in.

[0060] Specifically, if Figure 1 As shown, in this embodiment, the core seat 11 is provided with an air flow passage 112 extending in the direction of gravity, and the air hole 114 is provided on the inner wall of the upper end of the air flow passage 112 in the direction of gravity, adjacent to the atomizing groove 111. The air inlet 113 is provided on the side of the lower end of the air flow passage 112 in the direction of gravity, away from the atomizing groove 111. The oil drain hole 115 is provided on the end surface of the lower end of the air flow passage 112 in the direction of gravity. Here, in the embodiment of the present invention, for ease of description, with reference to the figure, a cross-sectional view of the air flow passage 112 is described. The air flow passage 112 is vertically arranged without a bend section, and the lower end of the air flow passage 112 is arranged in a through opening shape to form the oil drain hole 115. At the same time, the air hole 114 is provided at the upper right side of the air flow passage 112, and the air inlet 113 is provided at the lower left side of the air flow passage 112. When the smoke liquid enters the air passage 112 from the air hole 114 , it slides along the inner wall of the right side of the air passage 112 to the oil drain hole 115 under the action of gravity and is difficult to leak out from the air inlet hole 113 on the left side.

[0061] Specifically, in this embodiment, a number of support columns are provided protruding from the bottom cavity wall of the installation cavity 31. When the core seat 11 is installed in the installation cavity 31, it abuts against the support columns to form an oil collecting cavity 20 in a certain space between the bottom surface of the core seat 11 and the support of the bottom cavity wall of the installation cavity 31. The oil leaks from the oil drain hole 115 into the oil collecting cavity 20 for collection, so that no smoke liquid will remain in the entire airflow channel 112, thereby avoiding the airflow impacting the smoke liquid during the suction process to cause gurgling noises.

[0062] It is understandable that in actual application, the method is not limited to the above embodiment in which a plurality of support columns are protruding from the bottom wall of the installation cavity 31. Figure 3As shown, in an embodiment of the present invention, the mounting cavity 31 can also be designed as a stepped groove. When the core seat 11 is interference-fitted into the mounting cavity 31, the edge of the bottom surface of the core seat 11 abuts against the stepped surface 311 to form an oil collecting cavity 20. For example, two positioning protrusions 119 are provided at the top of the core seat 11. When the core seat 11 is inserted along the mounting cavity 31 until the positioning protrusions 119 contact the edges of the cavity opening of the mounting cavity 31, they abut and limit to form an oil collecting cavity 20 between the bottom surface of the core and the bottom cavity wall of the mounting cavity 31. Both of these methods fall within the protection scope of the present invention.

[0063] Specifically, if Figure 3 As shown, in an embodiment of the present invention, the base 30 is further provided with a positioning groove 35 corresponding to the positioning protrusion 119, for accommodating the positioning protrusion 119 and positioning the core seat 11, ensuring that when the core seat 11 is inserted into the base 30, the air inlet 113 is correspondingly connected with the second air inlet 32 ​​provided on the base 30.

[0064] Furthermore, if Figures 2 to 6 As shown, in this embodiment, the end surface of the positioning protrusion 119 away from the core seat 11 is also provided with a hook hole 1191 for inserting an external device. When the user needs to disassemble, the external disassembly device 300 can be inserted into the hook hole 1191 to apply force to the core seat 11 to pull the core seat 11 out of the installation cavity 31.

[0065] It is understandable that, in actual use, the method of setting the hook hole 1191 on the end surface of the positioning protrusion 119 away from the core seat 11 is not limited to the above embodiment. Figure 7 As shown, in other embodiments of the present invention, a hook hole 1191 can also be correspondingly opened on the surface of the top of the core seat 11 exposed from the cavity opening of the installation cavity 31, and then a hanging rod 21 can be provided in at least one hook hole 1191, or two hanging rods 21 can be directly provided at intervals in the atomization groove 111, so that the external disassembly device 300 can be hooked, which also falls within the scope of protection of the present invention.

[0066] Specifically, in order to prevent the residual liquid in the hook hole 1191 provided on the top of the core seat 11, in this embodiment, an opening communicating with the atomization groove 111 can be opened on one side of the hook hole 1191 to facilitate the discharge of the liquid in the hook hole 1191.

[0067] Specifically, if Figures 5 to 9As shown, in this embodiment of the present invention, the atomizer core component 10 further includes two conductive leads 123. The core base 11 is provided with two wire holes 117 on the surface where the atomizer tank 111 cavity is located. The two wire holes 117 are provided on both sides of the atomizer tank 111. One end of the two conductive leads 123 is fixedly connected to the heating component 12, and the other end passes through the wire holes 117 and emerges from the bottom surface of the core base 11 to establish an electrical connection with the electrode of the base 30, and the heating component 12 is mounted on the atomizer tank 111. Here, in this embodiment, the conductive leads 123 are integrally processed and formed with the heating element to form the conductive electrodes of the heating element. By providing two wire holes 117 on either side of the atomizer tank 111 for the two conductive leads 123 to pass through, the heating element 121 is suspended above the atomizer tank 111. The oil-absorbing portion of the oil-absorbing element 122 extends from both ends of the heating element 121 and then hangs down into the atomizer tank 111 to absorb the e-liquid. The heating element 121 does not contact the walls of the atomizer tank 111, preventing high-temperature conduction. Furthermore, the two conductive leads 123 are provided on either side of the atomizer tank 111 to support the heating element 121. This provides a more stable connection than providing two wire holes 117 on one side, effectively preventing the two conductive leads 123 from short-circuiting due to condensed water or oil.

[0068] Specifically, if Figure 1 、 Figure 2 、 Figure 4 or Figure 6 As shown, in this embodiment, a connection hole 116 is opened in the middle of the bottom surface of the core seat 11, and a conductive column 33 is provided in the middle of the base 30; one of the two conductive leads 123 passes through the wire hole 117 and is bent and inserted into the connection hole 116; when the core seat 11 is installed on the base 30, the conductive column 33 is inserted into the connection hole 116 by interference fit, and the conductive lead 123 is pressed against the inner wall of the connection hole 116 to establish an electrical connection. Here, in order to facilitate the user to Installation, the conductive column 33 is installed in the middle of the bottom wall of the installation cavity 31. When the core seat 11 is installed on the base 30, the conductive column 33 is inserted into the connection hole 116 provided in the base 30 with interference, effectively enhancing the interference area between the core seat 11 and the base 30, and enhancing the stability of the connection. At the same time, the conductive column 33 presses the conductive lead 123 against the inner wall of the connection hole 116 to prevent the conductive lead 123 from shaking, so as to establish a stable electrical connection with the conductive lead 123.

[0069] Specifically, if Figure 1 、 Figure 2 、 Figure 4 or Figure 6As shown, in an embodiment of the present invention, the base 30 is made of a conductive material, and at the same time, an insulating ring 34 is sleeved on the outer peripheral surface of the conductive column 33 to insulate and separate it from the base 30. The mounting cavity 31 of the base 30 is arranged in a stepped shape, and one of the two conductive leads 123 passes through the wire hole 117 and is bent to fit the edge of the bottom surface of the core seat 11; when the core seat 11 is inserted into the mounting cavity 31, one of the two conductive leads 123 is pressed to the step surface 311 by the bottom surface of the core seat 11 to establish an electrical connection with the base 30, and at the same time, an oil collecting cavity 20 is formed between the bottom surface of the core and the bottom cavity wall of the base 30. By directly pre-installing the two conductive leads 123 of the heating element 121 on the core seat 11, and then establishing an electrical connection with the base 30 by pressing, there is no need for welding, and there is no need for the traditional atomization core component 10 to be locked with screws or equipped with an adapter, which effectively facilitates user installation and effectively saves costs.

[0070] Specifically, if Figure 6 As shown, in order to facilitate the user to pre-install the conductive lead 123 on the core seat 11, in an embodiment of the present invention, two wiring grooves 1171 are also correspondingly opened on the bottom surface of the core seat 11. One end of the wiring groove 1171 is connected to the wire hole 117, and the other end extends to the connecting hole 116. One end of the other wiring groove is connected to the wire hole 117, and the other end extends to the edge of the bottom of the core seat 11. When the user installs it, it is only necessary to press the conductive lead 123 passing through the wire hole 117 along the wiring groove 1171 to pre-install the conductive lead 123 on the core seat 11, which effectively facilitates the user's assembly and improves processing efficiency. At the same time, the positioning installation effectively improves the product accuracy. When the core seat 11 is installed on the base 30, the wiring groove 1171 also has a limit on the conductive lead 123, which effectively prevents the conductive lead 123 from shaking during installation, causing the heating element 121 to be pulled out of position.

[0071] Specifically, if Figure 4As shown, in an embodiment of the present invention, the connecting hole 116 is connected to the atomizing tank 111, and the conductive column 33 is a hollow tube, in which the hollow portion forms an oil supply passage 331, and one end of the conductive column 33 is exposed to the outside from the base 30 for communicating with the external oil circuit, and the other end protrudes from the mounting cavity 31 for being inserted into the connecting hole 116 and communicating with the oil circuit of the atomizing tank 111. Here, in this embodiment, the connecting hole 116 is connected to the atomization tank 111, and the conductive column 33 is a hollow tube. When the core seat 11 is installed in the installation cavity 31, the hollow conductive column 33 and the connecting hole 116 form an oil supply channel 331, so that external oil can supply smoke liquid into the atomization tank 111 through the oil supply channel 331, thereby being absorbed by the oil absorption part located in the atomization tank 111. At the same time, excess oil can flow back to the external oil circuit through the connecting hole 116 to avoid being deposited in the atomization tank 111.

[0072] Furthermore, if Figure 4 As shown, in an embodiment of the present invention, a cover member 13 can be installed at the bottom of the atomizing tank 111, the cover member 13 covers the connecting hole 116, and a plurality of liquid ports 131 are opened on the side wall of the cover member 13 to connect the atomizing tank 111 and the connecting hole 116. The oil suction portion is accommodated in the atomizing tank 111 and covered by the liquid ports 131. Here, by providing the cover member 13 to cover the connecting hole 116 and then opening a plurality of liquid ports 131 on the side wall of the cover member 13, it is prevented that the oil is directly ejected from the connecting hole 116, and the instantaneous large amount of ejection impacts the heating element 121, resulting in the phenomenon of oil splashing.

[0073] Specifically, the cover member 13 can be integrally formed with the core seat 11, so as to facilitate processing. At the same time, a number of smaller-aperture liquid spray holes 132 can be opened on the surface of the cover member 13 facing the connecting hole 116. The liquid spray holes 132 are arranged facing the heating element 121, so as to avoid the phenomenon that the heating element 121 is dry-burned and causes damage to the oil guide part due to slow oil supply.

[0074] To achieve the above-mentioned objectives, the present invention further provides an electronic cigarette 1000, comprising a power supply device 200 and an atomization device 100 installed on the power supply device 200. Since the above-mentioned electronic cigarette 1000 adopts all the embodiments of the above-mentioned atomization device 100, it has at least all the beneficial effects of the above-mentioned embodiments, which will not be described one by one here.

[0075] Specifically, the power supply device 200 is provided with a power supply, a control panel, an oil storage device, an oil pumping device and an output electrode. When the atomization device 100 is installed on the power supply device 200, the conductive column 33 and the base 30 establish an electrical connection with the output electrode of the power supply device 200. At the same time, the oil pumping device can extract the oil in the oil storage device under the drive of the control panel, and then supply the oil to the atomization tank 111 through the oil supply channel 331 formed in the hollow part of the conductive column 33.

[0076] The specific working principle is as follows:

[0077] First, the user can control the oil extraction device through the button. The oil extraction device can use an air pump or a liquid extraction pump to draw the oil through the conductive column 33 and the connecting hole 116 into the atomization tank 111 for adsorption by the oil suction part. The oil suction part conducts the oil to the heating part 1221. Excess oil can flow back to the oil storage device through the oil supply channel 331 to avoid oil drying and contamination.

[0078] When the user inhales, the external air flows through the first air inlet of the shell 50, the second air inlet 32 ​​of the base 30, and the air inlet of the core seat 11 in sequence into the air flow channel 112, and then flows into the atomization chamber through the air hole 114, providing working airflow for the atomization device 100.

[0079] At the same time, the user drives the power supply through the output electrode to the base 30 and the conductive column 33 through the button or airflow sensor. At this time, the conductive column 33 and the base 30 conduct the current to the two conductive leads 123, thereby supplying power to the heating element 121 to generate heat, so as to evaporate the tobacco liquid adsorbed by the heat receiving part 1221 into smoke.

[0080] Finally, the external airflow mixes with the smoke and drives the smoke to flow through the atomization chamber and finally be discharged from the suction port 51 for the user to inhale.

[0081] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
