Technical Field
[0001] This application relates to the field of aerosol generation technology, and in particular to an exhaust component, an atomizing assembly, and an aerosol generation device. Background Technology
[0002] An aerosol generating device is a device used to generate aerosols from an aerosol matrix. An aerosol generating device generally includes an atomizer and an exhaust device. The atomizer generates aerosols from the aerosol matrix by means of heating or other methods. The aerosols flow to the outside of the aerosol generating device through the exhaust channel on the exhaust device.
[0003] In related technologies, aerosols disperse as they flow through the exhaust duct on the exhaust device to the outside of the generating device, causing the odor of the aerosols to be easily lost. Utility Model Content
[0004] This application provides an exhaust component, an atomizing assembly, and an aerosol generating device to improve the problem in the related art where aerosols disperse during the process of flowing through the exhaust channel on the exhaust component to the outside of the aerosol generating device, resulting in easy loss of the aerosol's odor.
[0005] In a first aspect, embodiments of this application provide an exhaust component, including a body, wherein an exhaust channel is provided inside the body, the exhaust channel having an inlet end and an outlet end facing away from each other, wherein aerosol can flow from the inlet end into the interior of the exhaust channel and can flow out of the exhaust channel from the outlet end, wherein the cross-sectional area of the outlet end is smaller than the cross-sectional area of the inlet end.
[0006] The exhaust component provided in this application has at least the following beneficial effects:
[0007] Since the exhaust component includes a main body, and the main body has an exhaust channel inside, the exhaust channel has an inlet end and an outlet end facing opposite directions, and the cross-sectional area of the outlet end is smaller than that of the inlet end, during the process of aerosol flowing from the inlet end into the interior of the exhaust channel and out of the exhaust channel from the outlet end, the flow velocity of the aerosol at the outlet end will be greater than that at the inlet end. This allows the aerosol to be better concentrated at the inlet end and discharged from the outlet end, thereby avoiding the problem of aerosol dispersion and loss of aerosol odor.
[0008] In some embodiments, the exhaust passage includes a first air passage and a second air passage that are connected to each other, wherein the end of the first air passage away from the second air passage is the air inlet end, and the end of the second air passage away from the first air passage is the air outlet end.
[0009] In some embodiments, the cross-sectional area of the first air passage gradually decreases from the air inlet end to the second air passage.
[0010] In some embodiments, the cross-sectional area of the second airway remains constant from the first airway to the air outlet.
[0011] In some embodiments, the cross-sectional area of the second airway gradually decreases from the first airway to the air outlet.
[0012] In some embodiments, the distance between the air intake and the second air passage is 11.5mm-13.5mm.
[0013] In some embodiments, the cross-sectional area of the first air passage remains constant from the air inlet to the second air passage, while the cross-sectional area of the second air passage gradually decreases from the first air passage to the air outlet.
[0014] In some embodiments, the first airway and the second airway are arranged coaxially.
[0015] In some embodiments, the cross-sectional area of the outlet end is 25%-35% of the cross-sectional area of the inlet end.
[0016] In some embodiments, the cross-sectional area of the outlet end is 24.4 mm². 2 The cross-sectional area of the air intake end is 79 mm². 2 .
[0017] Secondly, embodiments of this application provide an atomizing component, the atomizing component including an atomizer and an exhaust component as described in the first aspect, the atomizer being provided with an atomizing air passage, the atomizing air passage being correspondingly provided with the air inlet end.
[0018] The atomizing component provided in this application embodiment has at least the following beneficial effects:
[0019] Since the exhaust component of the atomizing assembly includes the main body, and the main body has an exhaust channel with an inlet and an outlet, and the cross-sectional area of the outlet is smaller than that of the inlet, the flow velocity of the aerosol at the outlet is greater than that at the inlet during the process of the aerosol flowing from the inlet to the interior of the exhaust channel and out of the exhaust channel. This allows the aerosol to be better concentrated at the inlet and discharged at the outlet, thus avoiding the problem of aerosol dispersion and loss of aerosol odor.
[0020] In some embodiments, two atomizing air channels are provided, and both atomizing air channels are provided corresponding to the air inlet end.
[0021] In some embodiments, the cross-section of the air inlet is elliptical, and the arrangement direction of the two atomizing air channels is parallel to the major axis of the ellipse.
[0022] In some embodiments, the atomizing component further includes a liquid-absorbing element disposed at the air inlet end, and the inner wall surface of the air inlet end is correspondingly disposed with at least a portion of the liquid-absorbing element.
[0023] Thirdly, embodiments of this application provide an aerosol generating device, which includes the atomizing component as described in the second aspect.
[0024] The aerosol generating apparatus provided in this application has at least the following beneficial effects:
[0025] Because its atomizing component's exhaust system includes the main body, which has an exhaust channel inside, and the exhaust channel has an inlet end and an outlet end facing opposite directions, and the cross-sectional area of the outlet end is smaller than that of the inlet end, during the process of the aerosol flowing from the inlet end into the interior of the exhaust channel and out of the exhaust channel from the outlet end, the flow velocity of the aerosol at the outlet end will be greater than that at the inlet end. This allows the aerosol to be better concentrated at the inlet end and discharged from the outlet end, thereby avoiding the problem of aerosol dispersion and loss of aerosol odor.

[0045] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.
[0046] An aerosol generating device is a device used to generate aerosols from an aerosol matrix. An aerosol generating device generally includes an atomizer and an exhaust device. The atomizer generates aerosols from the aerosol matrix by means of heating or other methods. The aerosols flow to the outside of the aerosol generating device through the exhaust channel on the exhaust device.
[0047] In related technologies, aerosols disperse as they flow through the exhaust duct on the exhaust device to the outside of the generating device, causing the odor of the aerosols to be easily lost.
[0048] In view of this, this application provides an exhaust component, an atomizing assembly, and an aerosol generating device. Since the exhaust component includes a body, and the body has an exhaust channel inside, the exhaust channel has an inlet end and an outlet end facing away from each other, and the cross-sectional area of the outlet end is smaller than that of the inlet end, during the process of the aerosol flowing from the inlet end into the interior of the exhaust channel and flowing out of the exhaust channel from the outlet end, the flow velocity of the aerosol at the outlet end will be greater than that at the inlet end. The aerosol can be better gathered together by the inlet end and discharged from the outlet end, thereby avoiding the problem of aerosol dispersion and loss of aerosol odor.
[0049] Please refer to Figures 1 to 6 , Figure 1 This is a schematic diagram of the structure of the aerosol generating device 100 in one embodiment of this application. Figure 2 yes Figure 1 The diagram shows a top view of the aerosol generating device 100. Figure 3 yes Figure 2 The aerosol generating apparatus 100 shown is a cross-sectional view along the MM direction. Figure 4 yes Figure 3 A magnified view of a portion of point A in the middle. Figure 5 yes Figure 1 The diagram shows the structure of the exhaust component 10 in the aerosol generating device 100. Figure 6 yes Figure 5 A structural schematic diagram of the exhaust component 10 from another perspective.
[0050] In a first aspect, embodiments of this application provide an exhaust component 10, including a body 101, an exhaust duct 102 disposed inside the body 101, the exhaust duct 102 having an inlet end 1021 and an outlet end 1022 facing away from each other, aerosol can flow from the inlet end 1021 into the interior of the exhaust duct 102 and can flow out of the exhaust duct 102 from the outlet end 1022, wherein the cross-sectional area of the outlet end 1022 is smaller than the cross-sectional area of the inlet end 1021.
[0051] The exhaust component 10 can be used in the atomization assembly of the aerosol generating device 100. The atomization assembly includes an atomizer for generating aerosol from the aerosol matrix 40. The aerosol can flow from the inlet end 1021 to the interior of the exhaust duct 102 and can flow out of the exhaust duct 102 from the outlet end 1022 to be discharged to the outside of the aerosol generating device 100.
[0052] The cross-sectional area of the exhaust duct 102 can be continuously reduced from the intake end 1021 to the exhaust end 1022, so that the cross-sectional area of the exhaust end 1022 is smaller than the cross-sectional area of the intake end 1021. Alternatively, the cross-sectional area of the exhaust duct 102 can be reduced in a stepped manner from the intake end 1021 to the exhaust end 1022, so that the cross-sectional area of the exhaust end 1022 is smaller than the cross-sectional area of the intake end 1021.
[0053] The exhaust duct 102 can be configured as a cone or an elliptical cone. Alternatively, the exhaust duct 102 can be configured as a combination of a cylinder and a cone. Or, the exhaust duct 102 can be configured as a combination of an elliptical cylinder and an elliptical cone. Other shapes are also possible. Correspondingly, the cross-sections of the exhaust end 1022 and the intake end 1021 can be configured as circular or elliptical shapes, etc. The flow direction of the aerosol can be approximately along the axial direction of the exhaust duct 102.
[0054] The cross-section of the outlet end 1022 can be a section perpendicular to the flow direction of the aerosol, and the cross-section of the inlet end 1021 can be a section perpendicular to the flow direction of the aerosol. For example, the cross-section of the outlet end 1022 can be a section perpendicular to the axis of the exhaust duct 102, and the cross-section of the inlet end 1021 can be a section perpendicular to the axis of the exhaust duct 102.
[0055] Because the cross-sectional area of the outlet end 1022 is smaller than that of the inlet end 1021, the flow rate of aerosol at the outlet end 1022 is greater than that at the inlet end 1021. The aerosol can be better concentrated at the inlet end 1021 and discharged from the outlet end 1022. The aerosol will not disperse, and the aroma and other odors of the aerosol are not easily lost.
[0056] As can be seen from the above, the exhaust device 10 provided in this application embodiment includes a body 101, and an exhaust channel 102 is provided inside the body 101. The exhaust channel 102 has an inlet end 1021 and an outlet end 1022 facing away from each other. The cross-sectional area of the outlet end 1022 is smaller than that of the inlet end 1021. Therefore, during the process of aerosol flowing from the inlet end 1021 into the interior of the exhaust channel 102 and flowing out of the exhaust channel 102 from the outlet end 1022, the flow velocity of the aerosol at the outlet end 1022 will be greater than that at the inlet end 1021. The aerosol can be better gathered together by the inlet end 1021 and discharged by the outlet end 1022, thereby avoiding the problem of aerosol dispersion and loss of aerosol odor.
[0057] Please refer to Figures 1 to 6 In this embodiment, the exhaust duct 102 includes a first air duct 11 and a second air duct 12 that are connected to each other. The end of the first air duct 11 that is away from the second air duct 12 is the air inlet 1021, and the end of the second air duct 12 that is away from the first air duct 11 is the air outlet 1022.
[0058] By adopting the above scheme, during the process of aerosol flowing from the inlet end 1021 into the interior of the first air passage 11 and continuing to flow out of the second air passage 12 from the outlet end 1022, the flow velocity of the aerosol at the outlet end 1022 will be greater than that at the inlet end 1021. This allows the aerosol to be better concentrated at the inlet end 1021 and discharged from the outlet end 1022, thereby avoiding the problem of aerosol dispersion and loss of aerosol odor.
[0059] Among them, from the air intake end 1021 to the second air passage 12, the cross-sectional area of the first air passage 11 gradually decreases.
[0060] This configuration allows aerosols to be better aggregated through the first airway 11, preventing aerosol dispersion.
[0061] Please refer to Figures 1 to 6 In this embodiment, the cross-sectional area of the second airway 12 from the first airway 11 to the air outlet 1022 remains unchanged.
[0062] This configuration allows for a more uniform flow rate and direction of aerosols in the second airway 12, thereby enabling aerosols flowing out of the second airway 12 from the outlet 1022 to be better received by other objects.
[0063] For example, the first air passage 11 is conical, the second air passage 12 is cylindrical, and each cross-section of the exhaust passage 102 is circular. Alternatively, the first air passage 11 is elliptical conical, the second air passage 12 is elliptical cylindrical, and each cross-section of the exhaust passage 102 is elliptical. Alternatively, the first air passage 11 is elliptical conical, the second air passage 12 is cylindrical, the cross-section of the first air passage 11 is elliptical, and the cross-section of the second air passage 12 is circular. Alternatively, the first air passage 11 is conical, the second air passage 12 is elliptical cylindrical, the cross-section of the first air passage 11 is circular, and the cross-section of the second air passage 12 is elliptical.
[0064] It should be noted that the first airway 11 and the second airway 12 can also be configured in other shapes.
[0065] Optionally, the distance H between the air intake end 1021 and the second air passage 12 is 11.5mm-13.5mm, such as 11.5mm, 12.0mm, 12.5mm, 13.0mm or 13.5mm.
[0066] This configuration allows aerosols to be better aggregated through the first airway 11, preventing aerosol dispersion.
[0067] It is understandable that the distance H between the air intake end 1021 and the second air passage 12 can be the length or height of the first air passage 11.
[0068] The first airway 11 and the second airway 12 are coaxially arranged.
[0069] This configuration allows the aerosol to flow more smoothly from the inlet 1021 into the first airway 11 and then out of the outlet 1022 into the second airway 12, preventing turbulence caused by obstruction. This also allows the aerosol flowing out of the outlet 1022 into the second airway 12 to be better received by other objects.
[0070] Optionally, the cross-sectional area of the air outlet 1022 is 25%-35% of the cross-sectional area of the air inlet 1021, such as 25%, 30% or 35%.
[0071] With this configuration, as the aerosol flows from the inlet end 1021 into the interior of the exhaust duct 102 and out of the exhaust duct 102 from the outlet end 1022, the flow velocity of the aerosol at the outlet end 1022 will be greater than that at the inlet end 1021. This allows the aerosol to be better concentrated at the inlet end 1021 and discharged from the outlet end 1022.
[0072] For example, the cross-sectional area of the air outlet 1022 is 24.4 mm². 2 The cross-sectional area of the intake end 1021 is 79 mm². 2 .
[0073] With this configuration, aerosols can be better gathered together through the air inlet 1021 and discharged through the air outlet 1022.
[0074] Among them, the flow rate of aerosol at the outlet 1022 can be increased by 2 times compared with the flow rate of aerosol at the inlet 1021. Experiments have verified that the aerosol flowing out of the second airway 12 is better received by other objects, resulting in a better user experience.
[0075] In another embodiment, the cross-sectional area of the second airway 12 gradually decreases from the first airway 11 to the air outlet 1022.
[0076] This configuration allows aerosols to be better aggregated through the second airway 12, preventing aerosol dispersion.
[0077] In another embodiment, from the air inlet 1021 to the second air passage 12, the cross-sectional area of the first air passage 11 remains unchanged, while from the first air passage 11 to the air outlet 1022, the cross-sectional area of the second air passage 12 gradually decreases.
[0078] This configuration allows aerosols to be better aggregated through the second airway 12, preventing aerosol dispersion.
[0079] Please refer to Figures 1 to 6 Secondly, embodiments of this application provide an atomizing component, which includes an atomizer and an exhaust component 10 as described in the first aspect. The atomizer is provided with an atomizing air passage 20, which is correspondingly provided with an air inlet 1021.
[0080] The atomizing component provided in this application embodiment includes a body 101 for the exhaust component 10. The body 101 has an exhaust channel 102 inside. The exhaust channel 102 has an air inlet end 1021 and an air outlet end 1022 facing away from each other. The cross-sectional area of the air outlet end 1022 is smaller than that of the air inlet end 1021. Therefore, during the process of the aerosol flowing from the air inlet end 1021 into the interior of the exhaust channel 102 and flowing out of the exhaust channel 102 from the air outlet end 1022, the flow velocity of the aerosol at the air outlet end 1022 will be greater than that at the air inlet end 1021. The aerosol can be better gathered together by the air inlet end 1021 and discharged by the air outlet end 1022, thereby avoiding the problem of aerosol dispersion and loss of aerosol odor.
[0081] It should be noted that the atomizer may include an atomizing core 30, which is configured in correspondence with the atomization channel. The atomizing core 30 is used to generate an aerosol from the aerosol matrix 40.
[0082] In this embodiment, two atomizing air channels 20 are provided, and both atomizing air channels 20 are corresponding to the air inlet 1021.
[0083] By adopting the above scheme, not only can the aerosol be better gathered together at the air inlet 1021 and discharged from the air outlet 1022, but the aerosol in the two atomizing air channels 20 can also be fully mixed through the exhaust channel 102.
[0084] Understandably, when two atomizing air channels 20 are provided, two atomizing cores 30 and two liquid storage chambers for storing aerosol matrix 40 can also be provided, with the atomizing core 30, liquid storage chamber, and atomizing air channel 20 being provided in a one-to-one correspondence. The two liquid storage chambers are completely independent. After the two aerosols generated by the aerosol generating matrix in the two liquid storage chambers are generated, they reach the air inlet 1021 of the exhaust device 10 from the atomizing air channel 20 respectively. Then, the two aerosols are fully mixed together in the exhaust channel 102 and then discharged together through the air outlet 1022.
[0085] The cross-section of the air inlet 1021 is elliptical, and the arrangement of the two atomizing air passages 20 is parallel to the major axis of the ellipse.
[0086] This arrangement facilitates the placement of the two atomizing channels 20, as well as the placement of the two atomizing cores 30 and the two aerosol matrices 40 corresponding to the two atomizing channels 20.
[0087] Optionally, the atomizing assembly also includes a liquid suction element 50, which is disposed at the air inlet 1021, and the inner wall surface of the air inlet 1021 corresponds to at least a portion of the liquid suction element 50.
[0088] This design allows the condensate formed in the exhaust duct 102 to flow back more effectively and be absorbed by the suction element 50, preventing the condensate from flowing out.
[0089] It should be noted that the liquid-absorbing component 50 can be configured as liquid-absorbing cotton, etc. The liquid-absorbing component 50 can be provided with a clearance hole 51 corresponding to the atomizing air channel 20, and the aerosol in the atomizing air channel 20 can reach the air inlet end 1021 of the exhaust component 10 through the clearance hole 51.
[0090] For example, the first air passage 11 is configured as an elliptical cone, the second air passage 12 is configured as an elliptical cylinder, and each cross-section of the exhaust passage 102 is elliptical.
[0091] This design allows for smooth airflow guidance of the aerosols through the first air duct 11, reducing turbulence and enabling the aerosols exiting the second air duct 12 to be more easily received by other objects, resulting in a better and more enhanced user experience. Furthermore, it improves the delivery of aerosol fragrance, as the aerosols become more concentrated, improving flavor transmission. Simultaneously, the first air duct 11 facilitates better condensate return, preventing condensate from flowing into the second air duct 12 and further enhancing the user experience.
[0092] Thirdly, embodiments of this application provide an aerosol generating device 100, which includes an atomizing component as described in the second aspect.
[0093] The aerosol generating device 100 provided in this application embodiment has an exhaust component 10 including a body 101. The body 101 has an exhaust channel 102 inside. The exhaust channel 102 has an inlet end 1021 and an outlet end 1022 facing away from each other. The cross-sectional area of the outlet end 1022 is smaller than that of the inlet end 1021. Therefore, during the process of aerosol flowing from the inlet end 1021 into the interior of the exhaust channel 102 and flowing out of the exhaust channel 102 from the outlet end 1022, the flow velocity of the aerosol at the outlet end 1022 will be greater than that at the inlet end 1021. The aerosol can be better gathered together through the inlet end 1021 and discharged through the outlet end 1022, thereby avoiding the problem of aerosol dispersion and loss of aerosol odor.
[0094] It should be noted that the aerosol generating device 100 provided in this application embodiment may also include a housing 60, a circuit board, a power supply, and a sealing element, etc., which will not be described in detail here.
[0095] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
