Technical Field

[0001] This application relates to the field of electronic atomization equipment technology, and in particular to an atomization device. Background Technology

[0002] Nebulizing fluids are typically composed of a mixture of multiple components, each with different temperature requirements for atomization or evaporation. Traditional atomizing devices use a single, integrated heating method for heating and atomization, and the resulting aerosol is then delivered through a single, integrated air channel. However, this method is not conducive to the efficient atomization and delivery of specific components, resulting in current atomizing devices being unable to meet the specific user's need for efficient absorption of particular components. Summary of the Invention

[0006] The liquid storage tank has an oil discharge channel that penetrates the pipe wall of the pipe body and communicates with the airflow channel;

[0007] An atomizing core is used to atomize a multi-component combination medium. The atomizing core includes an oil guide body and a heating component mounted on the oil guide body. The oil guide body is installed in the airflow channel, and the outer periphery of the oil guide body matches the inner wall of the airflow channel and is disposed opposite to the oil supply channel. The heating component includes a first heating unit and a second heating unit. The first heating unit is disposed in the second channel, and the second heating unit is disposed in the first channel.

[0008] Wherein, the heating temperature of the first heating unit is a first temperature, the heating temperature of the second heating unit is a second temperature, the first temperature is lower than the second temperature, and the combined medium flows from the oil channel to the oil guide body and then flows sequentially through the heating areas corresponding to the first heating unit and the second heating unit.

[0009] Furthermore, the porosity of the oil guide body at the position corresponding to the first heating unit is a first porosity, and the porosity of the oil guide body at the position corresponding to the second heating unit is a second porosity, wherein the first porosity and the second porosity are different.

[0010] Furthermore, the first heating unit and the second heating unit are at least partially misaligned along the axial direction of the oil guide body.

[0011] Furthermore, the outer periphery of the oil guide body is provided with a groove, and the groove and the inner wall of the airflow channel define one of the first channel and the second channel, the other of the first channel and the second channel being formed on the oil guide body.

[0012] Furthermore, the oil guide body includes a first part, a second part, and a third part connecting the first part and the second part. The first part and the second part are both hollow tubular structures. The first part is located on the outer periphery of the second part. One of the first channel and the second channel is defined between the inner wall of the first part and the outer wall of the second part. The inner wall of the second part encloses the other of the first channel and the second channel.

[0013] Furthermore, along the extension direction of the first channel, the length by which the third part overlaps with the first heating unit is equal to the length by which the third part overlaps with the second heating unit, and the third part is directly opposite the oil drain channel.

[0014] Furthermore, the oil guide body includes a first part and a second part, the first part surrounds the outer periphery of the second part, the lengths of the first part and the second part are not equal, the inner wall of the second part encloses to form the second channel, the outer wall of the second part defines the first channel between the inner wall of the second part and the airflow channel, and the first part is provided with a flow hole, the flow hole being used to connect the first channel with the airflow channel.

[0015] Furthermore, the heating times of the first heating unit and the second heating unit may be the same or different; and / or, the heating powers of the first heating unit and the second heating unit may be the same or different.

[0016] Furthermore, the absolute value of the difference between the first temperature and the second temperature is greater than 10°C.

[0017] Furthermore, the first channel and the second channel are independent of each other in the oil guide body, and the aerosol generated in the first channel and the aerosol generated in the second channel are mixed in the airflow channel.

The combined medium includes at least a first component and a second component. When the combined medium flows through the first heating unit, the first heating unit can heat and atomize the low-boiling-point first component, while preheating the non-first component (such as the second component). While achieving atomization of the first component, it can also enhance the fluidity of the non-first component, compensating for the disadvantage of the excessively long liquid guiding path of the non-first component as it flows from the lower oil channel to the second heating unit, thus facilitating the accelerated atomization and smoke emission of the non-first component. Furthermore, the first component and the second component are atomized in different channels, and the atomization temperature of both components can be set to a suitable atomization temperature for each component. This improves the atomization effect of the first component and the second component, thereby enhancing the user experience.

[0040] In the description of this application, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0041] See Figures 1 to 3 As shown, one embodiment of this application discloses an atomizing device, which has a first channel 310 and a second channel 320. The atomizing device includes a tube body 100, a liquid storage chamber 200 and an atomizing core 300.

[0042] Specifically, the tube body 100 has an airflow channel 110, which is connected to the first channel 310 and the second channel 320 respectively; the liquid storage chamber 200 has a liquid storage cavity 210 and an oil discharge channel 220, which 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 oil discharge channel 220; the atomizing core 300 is used to atomize the multi-component combined medium, and the atomizing core 300 includes an oil guide body and a heating component mounted 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 oil discharge channel 220; the heating component includes 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 region in the second channel 320, and the second heating unit 342 forms a second heating atomization region in the first channel 310. Different components of the combined medium are heated and atomized in the first heating atomization region and the second heating atomization region, respectively.

[0043] In practical applications, one end of the tube 100 is connected to the mouthpiece, and the other end is connected to the air inlet of the atomizing device. After the external airflow enters the airflow channel 110 through the air inlet, it can flow through the first channel 310 and the second channel 320, and flow together with the aerosol generated in the first channel 310 and the second channel 320 to the mouthpiece for the user to inhale.

[0044] In this embodiment, the heating temperature of the first heating unit 341 is a first temperature, and the heating temperature of the second heating unit 342 is a second temperature. The first temperature is lower than the second temperature. The combined medium includes a first component and a second component. The first temperature is higher than the boiling point temperature of the first component, and the second temperature is higher than the boiling point temperature of the second component.

[0045] It should be noted that in the embodiments of this application, after the combined medium flows from the lower oil channel 220 to the oil guide body, it flows sequentially 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.

[0046] In this embodiment, the first heating unit 341 and the second heating unit 342 are respectively disposed in the second channel 320 and the first channel 310. When the combined medium flows through the first heating unit 341, it can heat and atomize the low-boiling-point first component, while preheating the atomized medium of non-first components. While achieving heating and atomization of the first component, the first heating unit 341 can also be used to preheat the non-first components to enhance their flowability, thereby helping to compensate for the disadvantage of an excessively long liquid guiding path for the non-first components as they flow from the oil outlet channel 220 to the second heating unit 342. Furthermore, the first and second components are atomized in the second channel 320 and the first channel 310 respectively, and the atomization temperatures of both components are set at their appropriate atomization temperatures. This improves the atomization effect of both components, thereby enhancing the user experience. In addition, the first component and the second component are atomized in different atomization areas, which can effectively avoid the situation where the temperature gradient between the first heating unit 341 and the second heating unit 342 affects the atomization of other components, thus facilitating the maximum efficient atomization of each component.

[0047] In some embodiments of this application, see Figure 2 and Figure 3 As shown, when the first heating unit 341 and the second heating unit 342 are simultaneously disposed on the same structure and located on the inner and outer walls of the structure respectively, the first heating unit 341 and the second heating unit 342 are at least partially misaligned along the axial direction of the oil guide body. The axial direction of the oil guide body is as follows: Figure 2 or Figure 3 The X direction is shown in the diagram.

[0048] In one possible implementation, please continue to see Figure 2 and Figure 3As shown, the oil guide body includes a first part 331 and a second part 332, with the first part 331 disposed on the outer wall of the second part 332. The second part 332 has a first channel 310; the first part 331 has a groove extending along the length of the oil guide body, which, together with the inner wall of the tube body 100, defines a second channel 320. A first heating unit 341 is disposed at the bottom of the groove, i.e., on the outer wall of the second part 332, and a second heating unit 342 is disposed within the first channel 310. The first heating unit 341 and the second heating unit 342 are spaced apart or staggered along the length of the oil guide body.

[0049] During assembly, the oil drain channel 220 is positioned directly opposite the first heating unit 341. This minimizes the distance between the oil drain channel 220 and the first heating unit 341, allowing the combined medium in the reservoir 200 to flow from the oil drain channel 220 to the oil guide body. This ensures that the medium first flows through the portion of the first heating unit 341 corresponding to the oil guide body, and then flows 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 is first heated and atomized in the first heating and atomization area; simultaneously, the second component is preheated in the first heating and atomization area, and then flows to the second heating and atomization area for further heating and atomization.

[0050] In the above embodiments, the length of the first part 331 along the length direction of the oil guide body can be equal to or less than the length of the second part 332, and is not limited here.

[0051] See Figures 2 to 4 As shown, a groove is provided on the outer periphery of the oil guide body. This groove defines one of the second channel 320 and the first channel 310 between itself and the inner wall of the airflow channel 110. The other of the second channel 320 and the first channel 310 is formed on the oil guide body. Specifically, the lower oil channel 220 is opposite to the non-grooved position on the outer periphery of the oil guide body, that is, the non-grooved position on the outer periphery of the oil guide body abuts against the outlet of the lower oil channel 220. After the combined medium in the liquid storage tank 200 flows out of the lower oil channel 220, it can be guided by the oil guide body to the corresponding heating and atomization areas of the first heating unit 341 and the second heating unit 342.

[0052] In one possible implementation, see Figure 2 and Figure 3As shown, the groove and the inner wall of the airflow channel 110 define a second channel 320, in which the first heating unit 341 is disposed. Correspondingly, the first channel 310 is formed in the oil guide body, and the distance between the first channel 310 and the lower oil channel 220 is greater than the distance between the second channel 320 and the lower oil channel 220. In this way, it can be ensured that the combined medium can first flow through the heating and atomization area of ​​the first heating unit 341, 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 is conducive to the second component being guided through the oil guide body to the second heating unit 342 for heating and atomization in the second heating unit 342.

[0053] In another possible implementation, see Figure 4 As shown, the groove and airflow channel 110 define a first channel 310, and a second channel 320 is formed on the oil guide body, wherein the first channel 310 is located on the outer periphery of the second channel 320. Specifically, a first heating unit 341 is disposed within the second channel 320, and a second heating unit 342 is disposed within the first channel 310, with the first heating unit 341 and the second heating unit 342 being staggered in the extending direction of the first channel 310. When the atomizing core 300 is installed into the airflow channel 110 of the tube body 100, the oil outlet is aligned with the first heating unit 341. In this way, after the combined medium flows out of the lower oil channel 220, it can first flow through the heating atomization area of ​​the first heating unit 341, and then flow to the heating atomization area formed by the second heating unit 342.

[0054] In some embodiments of this application, see Figure 5 and Figure 6 As shown, the oil guide body includes a first part 331, a second part 332, and a third part 333 connecting the first part 331 and the second part 332. The first part 331 and the second part 332 are both hollow tubular structures. The first part 331 is sleeved on the outer periphery of the second part 332. The inner wall of the first part 331 and the outer wall of the second part 332 define a first channel 310. The second part 332 encloses a second channel 320.

[0055] In one possible implementation, please continue to see Figure 5 and Figure 6As shown, the length of the third part 333 along the axial direction is less than the length of the second part 332. The first heating unit 341 is disposed on the inner wall surface of the second part 332, and the second heating unit 342 is disposed on the outer wall surface of the second part 332. The second heating units 342 do not overlap in the radial direction of the oil guide body. The third part 333 is directly opposite the oil drain channel 220 of the liquid storage tank 200, meaning that the projection of the oil drain channel 220 along the radial direction of the oil guide body at least partially overlaps with the third part 333. Thus, the combined medium in the liquid storage tank 200 can be directly guided to the second part 332 through the third part 333. When the combined medium flows to the second part 332, it passes through the heating atomization area of ​​the first heating unit 341 and the heating atomization area of ​​the second heating unit 342.

[0056] In some embodiments of this application, see Figures 7 to 9 As shown, the oil guide body includes a first part 331, a second part 332, and a third part 333 connecting the first part 331 and the second part 332. Both the first part 331 and the second part 332 are hollow tubular structures. The second part 332 is fitted around the outer periphery of the first part 331. A second channel 320 is defined between the inner wall of the second part 332 and the outer wall of the first part 331. The first part 331 encloses the first channel 310. The third part 333 is directly opposite the oil discharge channel 220 of the liquid storage tank 200, that is, the projection of the oil discharge channel 220 in the radial direction along the oil guide body at least partially overlaps with the third part 333. During heating and atomization, the combined medium in the storage tank 200, after passing through the second part 332 via the oil outlet channel 220, can be directly guided to the first part 331 via the third part 333. During this process, the combined medium flows from the oil outlet channel 220 to the first part 331, passing successively through the heating and atomization areas of the first heating unit 341 and the second heating unit 342. Thus, the first component in the combined medium can be heated and atomized within the heating and atomization area of ​​the first heating unit 341, and the resulting aerosol can flow along the second channel 320 to the airflow channel 110. The second component in the combined medium is preheated within the heating and atomization area of ​​the first heating unit 341, accelerating its flow to the heating and atomization area of ​​the second heating unit 342, and ultimately atomized into an aerosol. The generated aerosol can then flow through the first channel 310 to the airflow channel 110. The aerosols formed by the atomization of the first component and the aerosols formed by the atomization of the second component are mixed in the airflow channel 110 and then guided into the user's mouth through the airflow channel 110, where they are inhaled by the user.

[0057] In some embodiments of this application, see Figure 9As shown, along the extension direction of the first channel 310, the length of overlap between the third part 333 and the first heating unit 341 is equal to the length of overlap between the third part 333 and the second heating unit 342. The third part 333 is directly opposite the lower oil channel 220 of the liquid storage chamber 200 of the atomizing device. This allows the combined medium to be uniformly guided to the upper and lower sides of the lower oil channel 220, enabling the first component in the combined medium to be heated by the first heating unit 341, thereby improving the uniformity of the atomization effect of the first component. Furthermore, by allowing the first component to be quickly distributed onto 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, reducing the lag time for the formation of aerosols from different components and improving the user experience.

[0058] Of course, the relative positions of the third part 333 and the oil channel 220 can also be set according to the atomization needs.

[0059] For example, the upper wall of the oil channel 220 may also be flush with the side of the third part 333 away from the second heating unit 342, so that the second component in the combined medium can be fully preheated by the first heating unit 341.

[0060] In some embodiments of this application, see Figure 10 and Figure 11 As shown, the oil guide body includes a first part 331 and a second part 332 surrounding the first part 331. The first part 331 is disposed on the outer periphery of the second part 332, and the second part 332 is provided with a second channel 320. The outer periphery of the second part 332 and the inner wall of the pipe body 100 enclose a first channel 310. The first part 331 is provided with a flow-through hole communicating with the first channel 310. This flow-through hole extends through both ends of the first part 331, allowing the upper end of the first channel 310 to communicate with the upper airflow channel 110 through the flow-through hole.

[0061] In some embodiments of this application, the oil guide body is made of porous ceramic. The porous ceramic has tiny pores inside, which can be used to transport the combined medium. Specifically, the oil guide body has a supply surface and an atomizing surface. The supply surface abuts against the outlet end of the lower oil channel 220. After the combined medium flows out of the lower oil channel 220, it can contact the supply surface. After contacting the supply surface, the combined medium can be transported to the atomizing surface through the tiny pores inside the oil guide body, and is heated and atomized by the heating component on the atomizing surface.

[0062] In some embodiments of this application, the porosity of the oil guide body corresponding to the position of the first heating unit 341 is a first porosity, and the porosity of the oil guide body corresponding to the position of the second heating unit 342 is a second porosity. The first porosity and the second porosity are different. Generally speaking, the porosity of the portion of the oil guide body closer to the first heating unit 341 is greater than the porosity of the portion of the oil guide body closer to the second heating unit 342. This can meet the conveying capacity requirements of the combined medium by the oil guide body and help ensure the supply speed of the combined medium.

[0063] In some embodiments of this application, the orifice diameter of the oil guide body at the position corresponding to the first heating unit 341 is a first orifice diameter, and the orifice diameter of the oil guide body at the position corresponding to the second heating unit 342 is a second orifice diameter, with the first orifice diameter being larger than the second orifice diameter. This facilitates the transport of the combined medium by the oil guide body.

[0064] In some embodiments of this application, the heating times of the first heating unit 341 and the second heating unit 342 may be the same or different. In practical applications, the heating times of the first heating unit 341 and the second heating unit 342 can be set according to the atomization requirements of the combined medium to achieve different heating effects.

[0065] In one 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 before the second heating unit 342, and the first heating unit 341 ends heating earlier than the second heating unit 342. In this way, insufficient heating and atomization of the second component due to the conduction path process can be effectively avoided.

[0066] 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 the actual atomization requirements. In some possible embodiments, the heating power of the first heating unit 341 and the second heating unit 342 is the same. Of course, in other embodiments, the heating power of the first heating unit 341 and the second heating unit 342 may be different.

[0067] In some embodiments of this application, the absolute value of the difference between the first temperature and the second temperature is greater than 10°C. This reduces the likelihood of components with different boiling points atomizing simultaneously in the same region, allowing different components in the combined medium to be atomized in different heating and atomization regions, thus optimizing the atomization effect of the combined medium.

[0068] In some embodiments of this application, the first channel 310 and the second channel 320 are independent of each other within the oil guide body. 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 areas. During atomization, the different components do not mix with each other. After atomization, the aerosols generated by the different components can flow along the first channel 310 and the second channel 320 to the airflow channel 110, mix in the airflow channel 110, and finally flow into the user's mouth and be inhaled.

[0069] It should be noted that in some other embodiments of this application, the combined medium includes a first component, a second component, and a third component. Correspondingly, the heating assembly includes a first heating unit 341, a second heating unit 342, and a third heating unit. Each heating unit forms an independent heating atomization area. The temperature of each heating atomization area is set according to the boiling point of each component to heat and atomize each component.

[0070] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
