Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0040] Referring to FIGS. 1-3, an aspect of the present application discloses an atomization device, the atomization device is formed with a first channel 310 and a second channel 320, the atomization device comprises a tube body 100, a liquid storage bin 200, and an atomization core 300.

[0041] Specifically, the tube body 100 has an airflow channel 110, the airflow channel 110 is in communication with the first channel 310 and the second channel 320 respectively; the liquid storage bin 200 has a liquid storage cavity 210 and a lower oil channel 220, the lower oil channel 220 is disposed through the tube wall of the tube body 100 to communicate with the airflow channel 110, so that the combined medium in the liquid storage cavity 210 can flow to the oil guide body through the lower oil channel 220; the atomization core 300 is configured to atomize multi-component combined medium, the atomization core 300 comprises an oil guide body and a heating assembly assembled on the oil guide body, the oil guide body is installed in the airflow channel 110, and the outer periphery of the oil guide body matches the inner wall of the airflow channel 110 and is disposed opposite to the lower oil channel 220; the heating assembly comprises a first heating unit 341 and a second heating unit 342, the first heating unit 341 is disposed in the second channel 320, and the second heating unit 342 is disposed in the first channel 310. The first heating unit 341 forms a first heating atomization area in the second channel 320, the second heating unit 342 forms a second heating atomization area in the first channel 310, and different components of the combined medium are heated and atomized in the first heating atomization area and the second heating atomization area respectively.

[0042] In actual application, one end of the tube body 100 is connected with a suction nozzle, and the other end is in communication with an air inlet hole of the atomization device. After external airflow flows into the airflow channel 110 from the air inlet hole, it can flow through the first channel 310 and the second channel 320, and flow to the suction nozzle together with the aerosol generated in the first channel 310 and the second channel 320, so as to be inhaled by the user.

[0043] In the present embodiment, the heating temperature of the first heating unit 341 is a first temperature, the heating temperature of the second heating unit 342 is a second temperature, the first temperature is less than the second temperature; the combined medium comprises a first component and a second component, the first temperature is greater than the boiling point temperature of the first component, and the second temperature is greater than the boiling point temperature of the second component.

[0044] It should be noted that in the embodiments of the present application, the combined medium flows from the oil passage 220 to the oil guide body, and then sequentially flows through the heating and atomization areas corresponding to the first heating unit 341 and the second heating unit 342. In this way, the multi-component combined medium can pass through the first heating unit 341 and the second heating unit 342 in sequence.

[0045] In the embodiments of the present application, the first heating unit 341 and the second heating unit 342 are respectively arranged in the second passage 320 and the first passage 310. When the combined medium flows through the first heating unit 341, the first component with a low boiling point can be heated and atomized, and the non-first component can be preheated. On the premise of achieving the heating and atomization of the first component, the first heating unit 341 can also be used to preheat the non-first component to enhance the fluidity of the non-first component, thereby helping to compensate for the disadvantage of the long liquid guide path of the non-first component from the oil passage 220 to the second heating unit 342. In addition, the first component and the second component are atomized in the second passage 320 and the first passage 310, respectively, and the atomization temperatures of the two components are set at appropriate atomization temperatures of their components. In this way, the atomization effect of the first component and the second component can be improved, thereby improving the user experience. In addition, the first component and the second component are atomized in different atomization areas, which can effectively avoid the situation that the first heating unit 341 and the second heating unit 342 affect the atomization of other components due to the existence of a temperature gradient, and is beneficial to realize the maximum efficiency atomization of each component.

[0046] In some embodiments of the present application, referring to FIGS. 2 and 3, for the case that the first heating unit 341 and the second heating unit 342 are arranged on the same structure and are located on the inner wall and the outer wall of the structure, respectively, the first heating unit 341 and the second heating unit 342 are at least partially arranged in a staggered manner in the axial direction of the oil guide body. The axial direction of the oil guide body is indicated by the X direction in FIGS. 2 or 3.

[0047] In a possible implementation, please continue to refer to FIGS. 2 and 3, the oil guide body includes a first part 331 and a second part 332, and the first part 331 is arranged on the outer wall of the second part 332. The second part 332 has the first passage 310, and the first part 331 has a groove extending in the length direction of the oil guide body, which defines the second passage 320 together with the inner wall of the pipe body 100. The first heating unit 341 is arranged on the bottom of the groove, i.e., the outer wall of the second part 332, and the second heating unit 342 is arranged in the first passage 310. The first heating unit 341 and the second heating unit 342 are arranged in a staggered manner in the length direction of the oil guide body.

[0048] When assembled, the oil outlet passage 220 is arranged opposite the first heating unit 341, so that the distance between the oil outlet passage 220 and the first heating unit 341 is short, and the combined medium in the liquid storage bin 200 can flow through the portion of the first heating unit 341 corresponding to the oil guide body first, and then flow to the area of the second heating unit 342 corresponding to the oil guide body. In this way, the first component in the combined medium can be heated and atomized in the first heating and atomization area first; at the same time, the second component is preheated in the first heating and atomization area, and then the second component flows to the second heating and atomization area for heating and atomization.

[0049] In the above embodiments, the length of the first portion 331 along the length direction of the oil guide body can be equal to the length of the second portion 332, or can be less than the length of the second portion 332, which is not limited here.

[0050] Referring to FIGS. 2-4, the outer periphery of the oil guide body is provided with a groove, which defines one of the second passage 320 and the first passage 310 with the inner wall of the airflow passage 110, and the other of the second passage 320 and the first passage 310 is formed on the oil guide body. Specifically, the oil outlet passage 220 is opposite the non-groove position of the outer periphery of the oil guide body, i.e., the non-groove position of the outer periphery of the oil guide body is opposite the outlet of the oil outlet passage 220, and the combined medium in the liquid storage bin 200 can be guided to the corresponding heating and atomization areas of the first heating unit 341 and the second heating unit 342 under the action of the oil guide body after flowing out of the oil outlet passage 220.

[0051] In one possible implementation, referring to FIGS. 2 and 3, the groove and the inner wall of the airflow passage 110 define the second passage 320, and the first heating unit 341 is arranged in the second passage 320. Correspondingly, the first passage 310 is formed in the oil guide body, and the distance between the first passage 310 and the oil outlet passage 220 is greater than the distance between the second passage 320 and the oil outlet passage 220. In this way, it can be ensured that the combined medium can flow through the heating and atomization area of the first heating unit 341 first, so that the first component can be heated and atomized by the first heating unit 341; at the same time, the second component can be preheated by the first heating unit 341, which facilitates the second component to be guided to the second heating unit 342 through the oil guide body for heating and atomization.

[0052] In another possible implementation, as shown in FIG. 4, the recess and the airflow passage 110 define a first passage 310, and a second passage 320 is formed on the oil guide body, wherein the first passage 310 is located at the outer periphery of the second passage 320. Specifically, a first heating unit 341 is arranged in the second passage 320, and a second heating unit 342 is arranged in the first passage 310, and the first heating unit 341 and the second heating unit 342 are arranged in a staggered manner in the extension direction of the first passage 310. When the atomizing core 300 is mounted to the airflow passage 110 of the tube body 100, the oil outlet hole is opposite to the first heating unit 341, so that after the combined medium flows out of the oil outlet passage 220, the combined medium can first flow through the heating and atomizing area of the first heating unit 341, and then flow to the heating and atomizing area formed by the second heating unit 342.

[0053] In some embodiments of the present application, as shown in FIGS. 5 and 6, the oil guide body includes a first portion 331, a second portion 332, and a third portion 333 connecting the first portion 331 and the second portion 332, and the first portion 331 and the second portion 332 are both hollow tubular structures. The first portion 331 is sleeved on the outer periphery of the second portion 332, and the inner wall of the first portion 331 and the outer wall of the second portion 332 define the first passage 310, and the second portion 332 encloses the second passage 320.

[0054] In a possible implementation, as shown in FIGS. 5 and 6, the length of the third portion 333 in the axial direction is less than the length of the second portion 332, the first heating unit 341 is arranged on the inner wall surface of the second portion 332, the second heating unit 342 is arranged on the outer wall surface of the second portion 332, and the second heating unit 342 does not overlap in the radial direction of the oil guide body; the third portion 333 is opposite to the oil outlet passage 220 of the liquid storage bin 200, that is, the projection of the oil outlet passage 220 in the radial direction of the oil guide body at least partially overlaps the third portion 333. In this way, the combined medium in the liquid storage bin 200 can be directly guided to the second portion 332 through the third portion 333, and when the combined medium flows to the second portion 332, it successively passes through the heating and atomizing area of the first heating unit 341 and the heating and atomizing area of the second heating unit 342.

[0055] In some embodiments of the present application, referring to FIGS. 7-9, the oil guide body includes a first portion 331, a second portion 332, and a third portion 333 connecting the first portion 331 and the second portion 332. The first portion 331 and the second portion 332 are both hollow tubular structures, and the second portion 332 is sleeved on the outer periphery of the first portion 331. The inner wall of the second portion 332 and the outer wall of the first portion 331 define a second channel 320 therebetween, and the first portion 331 encloses a first channel 310. The third portion 333 is opposite to the lower oil channel 220 of the liquid storage tank 200, i.e., the projection of the lower oil channel 220 in the radial direction of the oil guide body at least partially overlaps the third portion 333. When heated and atomized, the combined medium in the liquid storage tank 200 can be directly guided to the first portion 331 through the third portion 333 after passing through the second portion 332 from the lower oil channel 220. In this process of flowing from the lower oil channel 220 to the first portion 331, the combined medium passes through the heating and atomization area of the first heating unit 341 and the heating and atomization area of the second heating unit 342 in sequence. In this way, the first component in the combined medium can be heated and atomized in the heating and atomization area of the first heating unit 341, and the aerosol formed after atomization can flow along the second channel 320 to the airflow channel 110; the second component in the combined medium can be preheated in the heating and atomization area of the first heating unit 341, which can accelerate the flow to the heating and atomization area of the second heating unit 342, and finally atomized into aerosol, which can flow to the airflow channel 110 through the first channel 310. The aerosol formed by atomization of the first component and the aerosol formed by atomization of the second component are mixed in the airflow channel 110 and then guided to the user's mouth through the airflow channel 110, and then inhaled by the user.

[0056] In some embodiments of the present application, referring to FIG. 9, along the extension direction of the first channel 310, the length of the third portion 333 overlapping the first heating unit 341 is equal to the length of the third portion 333 overlapping the second heating unit 342, and the third portion 333 is opposite to the lower oil channel 220 of the liquid storage tank 200 of the atomization device. In this way, the combined medium can be uniformly guided to the upper side and the lower side of the lower oil channel 220, so that the first component in the combined medium can be heated by the first heating unit 341, thereby improving the uniformity of the atomization effect of the first component. In addition, by allowing the first component to be quickly distributed on the atomization surface of the first heating unit 341, the second component in the combined medium can also be quickly guided to the heating and atomization area of the second heating unit 342 after being preheated by the first heating unit 341, so as to reduce the generation lag time of aerosols of different components, thereby improving the user experience.

[0057] Of course, the relative position of the third portion 333 and the lower oil channel 220 can also be set according to the atomization needs.

[0058] For example, the upper wall of the oil outlet channel 220 can also be flush with the side of the third portion 333 away from the second heating unit 342, so that the second component in the combined medium can be sufficiently preheated by the first heating unit 341.

[0059] In some embodiments of the present application, referring to FIGS. 10 and 11, the oil guide body includes a first portion 331 and a second portion 332 surrounding the first portion 331, the first portion 331 is arranged at the outer periphery of the second portion 332, the second portion 332 is provided with a second channel 320, and the outer periphery of the second portion 332 and the inner wall of the pipe body 100 enclose a first channel 310. The first portion 331 is provided with a flow hole communicating with the first channel 310, the flow hole penetrates through both ends of the first portion 331, so that the upper end of the first channel 310 can communicate with the airflow channel 110 at the upper end through the flow hole.

[0060] In some embodiments of the present application, the oil guide body is made of porous ceramic. The interior of the porous ceramic has tiny pores that can be used to transport the combined medium. Specifically, the oil guide body has a liquid supply surface and an atomization surface, the liquid supply surface abuts the liquid outlet end of the oil outlet channel 220, and after the combined medium flows out of the oil outlet channel 220, it can come into contact with the liquid supply surface. After the combined medium comes into contact with the liquid supply surface, it can be transported to the atomization surface through the tiny pores in the interior of the oil guide body and be heated and atomized by the heating assembly at the atomization surface.

[0061] In some embodiments of the present application, the porosity of the oil guide body at the position corresponding to the first heating unit 341 is a first porosity, the porosity of the oil guide body at the position corresponding to the second heating unit 342 is a second porosity, and the first porosity is different from the second porosity. Generally, the porosity of the part of the oil guide body close to the first heating unit 341 is greater than the porosity of the part of the oil guide body close to the second heating unit 342, so that the demand for the amount of combined medium transported by the oil guide body can be met, and the supply speed of the combined medium can be ensured.

[0062] In some embodiments of the present application, the pore diameter of the oil guide body at the position corresponding to the first heating unit 341 is a first pore diameter, and the pore diameter of the oil guide body at the position corresponding to the second heating unit 342 is a second pore diameter, and the first pore diameter is greater than the second pore diameter. In this way, the oil guide body can conveniently transport the combined medium.

[0063] In some embodiments of the present application, the heating time of the first heating unit 341 and the second heating unit 342 is the same or different. In actual application, the heating time of the first heating unit 341 and the second heating unit 342 can be set according to the atomization needs of the combined medium to achieve different heating effects.

[0064] In a possible implementation, the heating time of the first heating unit 341 and the second heating unit 342 is the same. Specifically, the first heating unit 341 starts heating earlier than the second heating unit 342, and the first heating unit 341 ends heating earlier than the second heating unit 342. In this way, the insufficient heating and atomization of the second component due to the conduction path process can be effectively avoided.

[0065] It should be understood that the heating power of the first heating unit 341 and the second heating unit 342 is specifically set according to actual atomization requirements. In some possible implementations, the heating power of the first heating unit 341 and the second heating unit 342 is the same. Of course, in some other implementations, the heating power of the first heating unit 341 and the second heating unit 342 can also be different.

[0066] In some embodiments of the present application, the absolute value of the difference between the first temperature and the second temperature is greater than 10°C. In this way, the simultaneous atomization of components with different boiling points in the same region can be reduced, that is, the different components in the combined medium can be atomized in different heating and atomization regions, which is beneficial to optimizing the atomization effect of the combined medium.

[0067] In some embodiments of the present application, the first channel 310 and the second channel 320 are independent of each other in the oil guide body, and the aerosol generated in the first channel 310 and the aerosol generated in the second channel 320 are mixed in the airflow channel 110. That is, different components of the combined medium are heated and atomized in different regions, and the different components do not mix with each other during atomization. The aerosols corresponding to the different components generated after atomization can flow to the airflow channel 110 along the first channel 310 and the second channel 320, and are mixed in the airflow channel 110, and finally flow to the user's mouth and be smoked.

[0068] It should be pointed out that in some other embodiments of the present application, the combined medium includes a first component, a second component and a third component, and the heating assembly corresponds to a first heating unit 341, a second heating unit 342 and a third heating unit. Each heating unit forms an independent heating and atomization region, and the temperature of each heating and atomization region is set according to the boiling point of each component to heat and atomize each component.

[0069] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
