Description

Technical Field

[0001] The present invention relates to the field of atomization technology, and in particular to an atomization component, an atomization device and an aerosol generating equipment. Background Art

[0002] Cigarette smoke contains harmful substances such as tar, which can be very harmful to the human body if inhaled for a long time. To overcome the harmful substances produced by cigarette combustion, low-harm cigarette alternatives such as e-cigarettes with e-liquids and heat-not-burn e-cigarettes have emerged.

[0003] However, traditional electronic cigarettes have the problem that the atomizer core is easily blocked and cannot work. Summary of the Invention

[0004] Based on this, in order to address the above problems, it is necessary to provide an atomization component, an atomization device and an aerosol generating equipment.

[0005] The present application relates to an atomizing assembly, which comprises:

[0006] a substrate and a heating element at least partially in contact with the substrate;

[0007] The substrate is penetrated by an atomizing air channel and an air vent, part of the outer peripheral surface of the substrate is a feed surface, and the air vent is located on the side of the atomizing air channel away from the feed surface. The substrate contacts the atomizing medium through the feed surface and transfers the atomizing medium to the atomizing air channel and the air vent.

[0008] When the atomizer core of a traditional electronic cigarette is blocked by the e-liquid, it cannot be ventilated. When the user inhales, the microphone inside the electronic cigarette cannot detect the change in airflow, and the atomizer core cannot work. However, the atomizer assembly of the present application can transfer the atomizer medium to the atomizing airway after the feed surface of the substrate contacts the atomizing medium. The heating element can provide heat to the substrate to atomize the atomizing medium in the atomizing airway to form an aerosol that can be inhaled. In addition, the substrate is also provided with a vent hole, and the vent hole is located on the side of the atomizing airway away from the feed surface. Such a setting includes at least the following beneficial effects:

[0009] First, a vent is added outside the atomizing airway. Even if the atomizing medium in the atomizing airway is too much and blocked by the atomizing medium, the vent can maintain ventilation, ensuring that the airflow change can be detected. When the airflow change is detected, the atomizing component can start working, and the heating element generates heat to promote the atomization of the atomizing medium that is blocked and accumulated in the atomizing airway, thereby re-opening the atomizing airway.

[0010] Secondly, the vent is located on the side of the atomizing airway away from the feed surface. The feed surface will give priority to transferring the atomizing medium into the atomizing airway. On the one hand, sufficient atomizing medium can be supplied to the atomizing airway to avoid problems such as dry burning due to insufficient atomizing medium supply. On the other hand, the vent is far from the feed surface, and the atomizing medium is supplied to the atomizing airway first. Therefore, less atomizing medium is transferred to the vent, which can prevent the vent from being blocked by the atomizing medium and ensure the conduction of the vent.

[0011] Third, when the atomizing airway is blocked by the atomizing medium, when the user begins to inhale, the atomizing assembly begins to work, and the atomizing airway may not be in a conductive state, and the atomizing airway may not be able to generate aerosol immediately. However, since there is a certain amount of atomizing medium in the vent at this time, the atomizing medium in the vent can also be atomized to form a certain amount of aerosol immediately to supply the user's inhalation, ensuring a better user experience.

[0012] Fourthly, compared with methods such as adding a separate sensor airway outside the base for detecting airflow changes, the solution of the present application directly sets the vent holes on the base. On the one hand, the process and structure are simpler, which can reduce the manufacturing difficulty and cost. On the other hand, there is no need to add other additional components, which undoubtedly saves the internal space of the product, is conducive to the simplification and miniaturization of the product, and is more popular with users.

[0013] In one embodiment, the atomizing air passage and the vent are both opened along the axial direction of the base body. On the cross section of the base body, any point on the inner peripheral surface of the vent is a first reference point, and any point on the feed surface is a second reference point. The distance between the first reference point and the second reference point is a first distance. The maximum distance between the second reference point and the nearest inner peripheral surface of the atomizing air passage is a second distance. The first distance is greater than or equal to the second distance. Such a setting can be considered as the feed surface being closer to the atomizing air passage as a whole. The feed surface will preferentially supply the atomizing medium to the atomizing air passage. Then, the amount of smoke oil that the vent can receive is less than that of the atomizing air passage, which can avoid the vent being blocked due to excessive atomizing medium supply as much as possible.

[0014] In one embodiment, the atomizing air duct is provided in plurality, and the inner peripheral surface of the atomizing air duct closest to the second reference point has a third reference point that is farthest from the second reference point, and the distance between the third reference point and the second reference point is the second distance. The reason for emphasizing that the atomizing air duct must be the one closest to the second reference point is that other atomizing air ducts may be farther away from the second reference point, or even farther away than the distance from the second reference point to the first reference point of the vent, but the second reference point of the feed surface will preferentially transfer the atomizing medium to the atomizing air duct closest to it, and the second reference point of the feed surface contributes very little to the transport of the atomizing medium in other atomizing air ducts. The reason for emphasizing that the third reference point must be the point farthest from the inner peripheral surface of the closest atomizing channel to the second reference point is that the atomizing medium from the second reference point of the feed surface needs to be transmitted to the third reference point, which is the farthest away from the atomizing air duct, from the periphery of the atomizing air duct, so the actual transmission distance of the atomizing medium is greater than the straight-line distance between the second reference point and the third reference point.

[0015] In one embodiment, the vent holes are provided in plurality, and any point on the inner peripheral surface of one of the vent holes closest to the feed surface is the first reference point.

[0016] In one embodiment, the feed surface is provided in plurality, and the plurality of feed surfaces are distributed at intervals along the circumference of the substrate on the outer peripheral surface of the substrate, and any point on any feed surface is the second reference point.

[0017] In one embodiment, the atomizing air channel is provided in plurality, and the atomizing air channel corresponds to the feed surface in number and position.

[0018] In one embodiment, the vent hole is formed by solely enclosing the base.

[0019] In one embodiment, the atomizer assembly further comprises an atomizer sleeve, which is sleeved on the outer circumferential surface of the base. The outer circumferential surface of the base is provided with a groove, which extends axially through the base. The inner wall of the atomizer sleeve and the groove wall enclose the vent. Because the inner circumferential surface of the vent is divided into the wall of the atomizer sleeve, and a small gap objectively exists at the junction of the wall and the groove wall, the atomizer sleeve can effectively prevent the atomized medium such as smoke oil from accumulating in a certain place due to surface tension, thereby clogging the vent.

[0020] In one embodiment, the atomizing assembly further includes an atomizing sleeve, which is sleeved on the outer circumferential surface of the base body. A feed port is provided through the side circumferential surface of the atomizing sleeve, and the feed surface is at least partially exposed through the feed port to contact the atomizing medium.

[0021] In one embodiment, the substrate is made of a porous material with a certain porosity. The substrate is porous at the microscopic level, and the atomizing medium is transported within the substrate through capillary action and then to the inner wall of the atomizing airway to be atomized to form an aerosol.

[0022] In one embodiment, the cross-sectional area of the vent hole is smaller than or equal to the cross-sectional area of the atomizing airway.

[0023] In one embodiment, the heat emitted by the heating element can be radiated from the inner peripheral surface of the atomizing air channel into the atomizing air channel; and / or the heating element is only provided in the atomizing air channel. This can be considered as the heating element being provided only in the atomizing air channel, or only in the vicinity of the atomizing air channel; and other air channels outside the atomizing air channel, such as the vents, are not provided with a heating element.

[0024] In one embodiment, the heating element covers the entire inner circumference of the atomizing air duct.

[0025] In one embodiment, the heating element is laid on the inner circumference of the atomizing air duct.

[0026] In one embodiment, the heating element is embedded in the inner peripheral surface of the atomizing air duct.

[0027] In one embodiment, the heating element is buried under the inner peripheral surface of the atomizing air duct.

[0028] In one embodiment, the heating element includes at least one of a spiral heating wire, a metal heating sheet, a metal heating mesh, and a resistance paste film.

[0029] The present application also relates to an atomization device, which includes a main body, a storage chamber and an atomization assembly as described in any of the above embodiments, wherein the storage chamber is arranged in the main body and is used to store the atomization medium, and the storage chamber is connected to the feed surface to transport the atomization medium to the feed surface.

[0030] In one embodiment, the atomizing device further includes a sensor element disposed within the main body, the main body being formed with an air inlet and an air outlet; one end of the atomizing air duct is connected to the air inlet, the other end of the atomizing air duct is connected to the air outlet, one end of the air vent is connected to the air inlet, the other end of the air vent is connected to the air outlet, and the sensor element is used to detect airflow changes in the airflow path between the air inlet and the air outlet. The sensor element may be a microphone, etc., which can detect airflow changes. If at least one of the atomizing air duct and the air vent is in a conducting state, when the user inhales from the air outlet, negative pressure will appear on the side of the sensor element close to the air outlet, and the sensor element can send a signal to start the atomizing device to start working.

[0031] The present application also relates to an aerosol generating device, which includes a power supply device and an atomization device as described in any of the above embodiments, wherein the power supply device is used to be electrically connected to the heating element to enable the heating element to generate heat.

[0032] The above-mentioned atomizing device and aerosol generating apparatus may be provided with the atomizing components described in the above-mentioned embodiments, and thus also have at least the following beneficial effects:

[0033] First, a vent is added outside the atomizing airway. Even if the atomizing medium in the atomizing airway is too much and blocked by the atomizing medium, the vent can maintain ventilation, ensuring that the airflow change can be detected. When the airflow change is detected, the atomizing component can start working, and the heating element generates heat to promote the atomization of the atomizing medium that is blocked and accumulated in the atomizing airway, thereby re-opening the atomizing airway.

[0034] Secondly, the vent is located on the side of the atomizing airway away from the feed surface. The feed surface will give priority to transferring the atomizing medium into the atomizing airway. On the one hand, sufficient atomizing medium can be supplied to the atomizing airway to avoid problems such as dry burning due to insufficient atomizing medium supply. On the other hand, the vent is far from the feed surface, and the atomizing medium is supplied to the atomizing airway first. Therefore, less atomizing medium is transferred to the vent, which can prevent the vent from being blocked by the atomizing medium and ensure the conduction of the vent.

[0035] Third, when the atomizing airway is blocked by the atomizing medium, when the user begins to inhale, the atomizing assembly begins to work, and the atomizing airway may not be in a conductive state, and the atomizing airway may not be able to generate aerosol immediately. However, since there is a certain amount of atomizing medium in the vent at this time, the atomizing medium in the vent can also be atomized to form a certain amount of aerosol immediately to supply the user's inhalation, ensuring a better user experience;

[0036] Fourthly, compared with methods such as adding a separate sensor airway outside the base for detecting airflow changes, the solution of the present application directly sets the vent holes on the base. On the one hand, the process and structure are simpler, which can reduce the manufacturing difficulty and cost. On the other hand, there is no need to add other additional components, which undoubtedly saves the internal space of the product, is conducive to the simplification and miniaturization of the product, and is more popular with users.

[0050] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0051] See also Figure 1 and Figure 2 , the present application provides an atomizing assembly 11, which includes a base 100 and a heating element 200. The heating element 200 is at least partially in contact with the base 100. Specifically, the base 100 is roughly columnar, and can be a cylindrical, cubic column, or the like. The shape of the base 100 described here is intended to clearly present the scheme, and is not intended to limit the shape of the base 100. More specifically, the base 100 is provided with mutually independent atomizing air channels 110 and air vents 120 along the axial direction, which can be considered as mutually unconnected atomizing air channels 110 and air vents 120. Part of the outer peripheral surface of the base 100 is a feed surface 130, and the air vents 120 are located on the side of the atomizing air channel 110 away from the feed surface 130. The base 100 contacts the atomizing medium through the feed surface 130 and transfers the atomizing medium to the atomizing air channel 110 and the air vents 120.

[0052] Among them, the atomizing medium may refer to a material that can be transferred through the substrate 100 and provide volatile components, such as tobacco oil. The substrate 100 can be made of a porous material with a certain porosity, such as ceramic or glass, that is, the substrate 100 presents a "porous" form at the microscopic level, and the atomizing medium is transferred inside the substrate 100 through capillary action, and the atomizing medium is transferred to the inner wall of the atomizing airway 110 to be atomized to form an aerosol. In the actual working process, the atomizing medium such as tobacco oil can be transferred to the inner wall of the atomizing airway 110 through the feed surface 130 of the substrate 100, and flow out to form multiple droplets over time and under the influence of gravity. The droplets will continue to gather under the action of surface tension without dripping, and the atomizing airway 110 may be blocked. In addition, the porosity range of the porous material used to manufacture the substrate 100 can be 20%-80%. Preferably, the porosity of the porous material can be 40%-80%. The porosity of the porous material can be adjusted according to the composition of the smoke liquid. For example, when the viscosity of the atomized medium such as smoke liquid is relatively high, a porous material with a relatively high porosity can be selected to form the base 100 to ensure the liquid guiding effect.

[0053] When the atomizing core of a traditional electronic cigarette is blocked by the e-liquid, it cannot be ventilated. Then, when the user inhales, the microphone inside the electronic cigarette cannot detect the change in airflow, and the atomizing core cannot work. However, the atomizing assembly 11 of the present application can transfer the atomizing medium to the atomizing airway 110 after the feed surface 130 of the base 100 contacts the atomizing medium, and the heating element 200 can provide heat to the base 100 to atomize the atomizing medium in the atomizing airway 110 to form an aerosol that can be inhaled. In addition, the base 100 is also provided with a vent 120, and the vent 120 is located on the side of the atomizing airway 110 away from the feed surface 130. Such a setting includes at least the following beneficial effects:

[0054] First, a vent hole 120 is provided outside the atomizing air passage 110. Even if the atomizing medium in the atomizing air passage 110 is excessive and blocked by the atomizing medium, the vent hole 120 can maintain ventilation, ensuring that airflow changes can be detected. When the airflow change is detected, the atomizing assembly 11 can start working, and the heating element 200 generates heat to atomize the atomizing medium that is blocked and accumulated in the atomizing air passage 110, thereby re-opening the atomizing air passage 110.

[0055] Secondly, the vent 120 is located on the side of the atomizing air channel 110 away from the feed surface 130, so the feed surface 130 will give priority to transferring the atomized medium into the atomizing air channel 110. On the one hand, sufficient atomized medium can be supplied to the atomizing air channel 110 to avoid problems such as dry burning of the atomizing air channel 110 due to insufficient supply of atomized medium. On the other hand, the vent 120 is farther away from the feed surface 130, and the atomized medium is preferentially supplied to the atomizing air channel 110. Therefore, less atomized medium is transferred into the vent 120, which can prevent the vent 120 from being blocked by the atomized medium, thereby ensuring the conduction of the vent 120.

[0056] Third, when the atomizing airway 110 is blocked by the atomizing medium, when the user begins to inhale, the atomizing assembly 11 begins to work, and the atomizing airway 110 may not be in a conductive state, and the atomizing airway 110 may not be able to generate aerosol immediately. However, since there is a certain amount of atomizing medium in the vent hole 120 at this time, the atomizing medium in the vent hole 120 can also be atomized to form a certain amount of aerosol immediately to supply the user with inhalation, ensuring a better user experience;

[0057] Fourthly, compared with methods such as separately adding a sensor airway outside the base 100 for detecting airflow changes, the solution of the present application directly sets the vent 120 on the base 100. On the one hand, the process and structure are simpler, which can reduce the manufacturing difficulty and manufacturing cost. On the other hand, there is no need to add other additional components, which undoubtedly saves the internal space of the product, is conducive to the simplification and miniaturization of the product, and is more popular with users.

[0058] Specifically, if Figure 3 In some embodiments, on a cross section of the substrate 100, any point on the inner circumferential surface of the vent hole 120 is a first reference point A, and any point on the feed surface 130 is a second reference point B. The distance between the first reference point A and the second reference point B is a first distance L1. The maximum distance between the second reference point B and the inner circumferential surface of the nearest atomizing air channel 110 is a second distance L2, and the first distance L1 is greater than or equal to the second distance L2.

[0059] For example, Figure 3 As shown, in some embodiments, the atomizing air duct 110 and the vent 120 are both set as one, then the point on the inner circumference of the atomizing air duct 110 that is farthest from the second reference point B is the third reference point C, and the distance between the third reference point C and the second reference point B is the second distance L2.

[0060] For example, Figure 4 As shown, in other embodiments, the atomizing airway 110 may be provided in multiple forms, such as Figure 2There are at least two atomizing air passages 110. The inner circumferential surface of the atomizing air passage 110 closest to the second reference point B has a third reference point C that is farthest from the second reference point B. This means that the point on the inner circumferential surface of the atomizing air passage 110 closest to the second reference point B is farthest from the second reference point B. The distance between the third reference point C and the second reference point B is a second distance L2. This arrangement can be considered to place the feed surface 130 closer to the atomizing air passage 110 as a whole. The feed surface 130 will preferentially supply the atomizing medium to the atomizing air passage 110. As a result, the amount of e-liquid that can be received by the vent 120 is less than that of the atomizing air passage 110, minimizing the risk of clogging the vent 120 due to an excessive supply of atomizing medium.

[0061] The reason why it is important to select the atomizing air channel 110 closest to the second reference point B is that the other atomizing air channels 110 may be farther away from the second reference point B, or even farther away than the distance from the second reference point B to the first reference point A of the vent 120. However, the second reference point B of the feed surface 130 will preferentially transfer the atomizing medium to the atomizing air channel 110 closest to it, and the second reference point B of the feed surface 130 will make little contribution to the transfer of the atomizing medium to the other atomizing air channels 110. For example, Figure 4 As shown, the atomizing air channel 110 is set to two, including a first atomizing air channel 111 and a second atomizing air channel 112 which are spaced apart from each other. The second atomizing air channel 112 is farther away from the second reference point B of the feed surface 130. The second atomizing air channel 112 and the second reference point B are almost separated by the first atomizing air channel 111. It is not difficult to see that the second reference point B of the feed surface 130 contributes very little to the transportation of the atomizing medium in the second atomizing air channel 112.

[0062] The reason why the third reference point C must be the point closest to the inner peripheral surface of the atomizing channel and the point farthest from the second reference point B is that the atomized medium at the second reference point B of the feed surface 130 needs to be transmitted to the third reference point C, which is the farthest distance from the atomizing air channel 110, by bypassing the periphery of the atomizing air channel 110. Therefore, the actual transmission distance of the atomized medium is greater than the straight-line distance between the second reference point B and the third reference point C. For example, Figure 3 and Figure 4 As shown, the atomized medium at the second reference point B of the feed surface 130 needs to be transferred to the third reference point C, that is, to the side of the atomizing air channel 110 facing away from the second reference point B. The atomized medium needs to be transferred from both sides of the atomizing air channel 110 along the periphery.

[0063] More specifically, if Figure 3 and Figure 4As shown, in some embodiments, the cross-sectional profile of the atomizing air duct 110 is circular, and the line connecting the second reference point B and the third reference point C passes through the center of the circular cross-sectional profile of the atomizing air duct 110. In other embodiments, the cross-sectional profile of the atomizing air duct 110 may also be rectangular, triangular, diamond-shaped, or a regular or irregular polygon. In other words, this application does not limit the cross-sectional profile of the atomizing air duct 110. Similarly, this application does not limit the shape of the cross-sectional profile of the vent hole 120 in each embodiment, and will not be elaborated here.

[0064] More specifically, if Figure 5 As shown, in some embodiments, a plurality of vent holes 120 may be provided, and any point on the inner peripheral surface of a vent hole 120 closest to the feed surface 130 is the first reference point A.

[0065] More specifically, if Figure 5 As shown, in some embodiments, the feed surface 130 is provided in plurality, and the plurality of feed surfaces 130 are distributed along the circumference of the substrate 100 at intervals on the outer peripheral surface of the substrate 100, and any point on any feed surface 130 is the second reference point B. For example, in Figure 5 As shown, in some embodiments, a plurality of atomizing air channels 110 are provided, and the atomizing air channels 110 correspond one-to-one in number and position to the feed surfaces 130. For example, in other embodiments, only one atomizing channel may be provided, while multiple feed surfaces 130 are provided. The multiple feed surfaces 130 are distributed along the circumference of the substrate 100 at intervals on the outer peripheral surface of the substrate 100, and the multiple feed surfaces 130 correspond to one atomizing channel at a time.

[0066] More specifically, in some embodiments, the cross-sectional area of the vent 120 is less than or equal to the cross-sectional area of the atomizing airway 110. Figures 1 to 6 As shown, the cross-sectional area of the vent holes 120 is smaller than the cross-sectional area of the atomizing air channel 110 .

[0067] More specifically, if Figure 6 and Figure 7 As shown, in some embodiments, the atomizing assembly 11 further includes an atomizing sleeve 300, which is sleeved on the outer peripheral surface of the substrate 100, and a feed port 310 is provided on the side peripheral surface of the atomizing sleeve 300, and the feed surface 130 is at least partially exposed through the feed port 310 to contact the atomizing medium. For example, in some embodiments, the feed surface 130 may refer to that only a part of the outer peripheral surface of the substrate 100 itself is a feed surface, which can absorb atomizing media such as smoke oil, and the rest of the outer peripheral surface can be a non-porous material or a low-porosity material, which does not absorb the atomizing medium. For another example, Figure 7 and Figure 9As shown, in other embodiments, the substrate 100 can be considered to be made of a porous material as a whole, and the entire outer peripheral surface can absorb atomized media such as smoke oil. Then, the outer peripheral surface of the substrate 100 that is only exposed at the feed port 310 can be considered as the feed surface 130.

[0068] There are many ways to form the vent hole 120 of the present application, for example, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, in some embodiments, the vent hole 120 is formed by the base 100 alone.

[0069] For example, Figure 8 and Figure 9 As shown, in other embodiments, the atomizer assembly 11 further includes an atomizer sleeve 300, which is sleeved on the outer circumferential surface of the base 100. The outer circumferential surface of the base 100 is provided with a groove, which penetrates the base 100 along the axial direction of the base 100. The inner tube wall of the atomizer sleeve 300 and the groove wall of the groove enclose a vent 120. Since the inner circumferential surface of the vent 120 is divided into the tube wall of the atomizer sleeve 300, and there is objectively a small gap at the junction of the tube wall and the groove wall, it can effectively prevent the atomized medium such as smoke oil from gathering in a certain place due to the effect of surface tension, thereby causing clogging of the vent 120.

[0070] See also Figure 2 In some embodiments, the heat emitted by the heating element 200 can be radiated from the inner peripheral surface of the atomizing air channel 110 into the atomizing air channel 110. This can be considered as the heating element 200 being only arranged in the atomizing air channel 110, or only arranged near the atomizing air channel 110; while other air channels outside the atomizing air channel 110, such as the vent 120, are not provided with the heating element 200. It can be considered that only the atomizing air channel 110 is provided with the heating element 200, while the vent 120 is not provided with a heat source. The atomizing medium in the atomizing air channel 110 can be quickly atomized under the heating of the heating element 200, and the atomizing medium content in the substrate 100 near the atomizing air channel 110 may be reduced, and the atomizing medium in the substrate 100 will be preferentially supplied to the atomizing air channel 110. Among them, the heating element 200 can be at least one of a spiral heating wire, a metal heating sheet, a metal heating mesh, and a resistor paste film.

[0071] Specifically, in some embodiments, the heating element 200 is embedded in the inner circumference of the atomizing air duct 110, that is, the heating element 200 is partially located below the inner circumference of the atomizing air duct 110, and partially located above the inner circumference of the atomizing air duct 110, that is, partially exposed in the atomizing air duct 110.

[0072] Specifically, in some other embodiments, the heating element 200 is buried under the inner peripheral surface of the atomizing air duct 110 , that is, the heating element 200 is not exposed in the atomizing air duct 110 .

[0073] Specifically, in other embodiments, the heating element 200 is laid on the inner circumference of the atomizing air duct 110 , that is, the heating element 200 is only arranged on the surface of the inner circumference and is not embedded in the inner circumference of the atomizing air duct 110 .

[0074] More specifically, for example, Figure 2 As shown, in some embodiments, the heating element 200 covers the entire inner circumference of the atomizing air channel 110. For example, in other embodiments, the heating element 200 can be distributed at a certain interval on the inner circumference of the atomizing air channel 110, or the heating element 200 can be hollow.

[0075] More specifically, in some embodiments, when a plurality of atomizing air ducts 110 are provided, a plurality of heating elements 200 may also be provided, and correspond one to one with the atomizing air ducts 110 .

[0076] In addition, if Figure 10 As shown, the present application also relates to an atomizing device 10, which includes a main body 12, a storage chamber (not shown), and an atomizing assembly 11 as described in any of the above embodiments. The storage chamber is provided in the main body 12 and is used to store the atomizing medium. The storage chamber is communicated with the feed surface 130 to deliver the atomizing medium to the feed surface 130.

[0077] Specifically, if Figure 10 As shown, in some embodiments, the atomizing device 10 further includes a sensor element 13 disposed within a main body 12, which is formed with an air inlet 121 and an air outlet 122. One end of the atomizing air passage 110 is in communication with the air inlet 121, and the other end of the atomizing air passage 110 is in communication with the air outlet 122. One end of the vent 120 is in communication with the air inlet 121, and the other end of the vent 120 is in communication with the air outlet 122. The sensor element 13 is used to detect changes in airflow in the atomizing air passage 110 and / or the vent 120. The sensor element 13 may be a microphone, etc. The sensor element 13 can detect airflow changes in the airflow path between the air inlet 121 and the air outlet 122. For example, when at least one of the atomizing airway 110 and the air vent 120 is in a conductive state and the user inhales from the air outlet 122, the sensor element 13 detects negative pressure on the side close to the air outlet 122, and the sensor element 13 can send a signal to start the atomizing device 10 to start working.

[0078] More specifically, if Figure 10As shown, in some embodiments, the sensor element 13 can be disposed between the air outlet 122 and the atomizer assembly 11. In other embodiments, the sensor element 13 can also be disposed between the air inlet 121 and the atomizer assembly 11. As long as the atomizer assembly 11 is not blocked, that is, at least one of the atomizing air passage 110 and the air vent 120 is in a conductive state, the sensor element 13 can function normally, thereby driving the heating element 200 of the atomizer assembly 11 to operate.

[0079] In addition, if Figure 10 As shown, the present application also relates to an aerosol generating device, which includes a power supply device 20 and an atomizing device 10 as any of the above embodiments, wherein the power supply device 20 is used to be electrically connected to the heating element 200 to enable the heating element 200 to generate heat.

[0080] The atomizing device 10 and the aerosol generating apparatus may be provided with the atomizing assembly 11 of each of the above embodiments, and thus, also have at least the following beneficial effects:

[0081] First, a vent hole 120 is provided outside the atomizing air passage 110. Even if the atomizing medium in the atomizing air passage 110 is excessive and blocked by the atomizing medium, the vent hole 120 can maintain ventilation, ensuring that airflow changes can be detected. When the airflow change is detected, the atomizing assembly 11 can start working, and the heating element 200 generates heat to atomize the atomizing medium that is blocked and accumulated in the atomizing air passage 110, thereby re-opening the atomizing air passage 110.

[0082] Secondly, the vent 120 is located on the side of the atomizing air channel 110 away from the feed surface 130, so the feed surface 130 will give priority to transferring the atomized medium into the atomizing air channel 110. On the one hand, sufficient atomized medium can be supplied to the atomizing air channel 110 to avoid problems such as dry burning of the atomizing air channel 110 due to insufficient supply of atomized medium. On the other hand, the vent 120 is farther away from the feed surface 130, and the atomized medium is preferentially supplied to the atomizing air channel 110. Therefore, less atomized medium is transferred into the vent 120, which can prevent the vent 120 from being blocked by the atomized medium, thereby ensuring the conduction of the vent 120.

[0083] Third, when the atomizing airway 110 is blocked by the atomizing medium, when the user begins to inhale, the atomizing assembly 11 begins to work, and the atomizing airway 110 may not be in a conductive state, and the atomizing airway 110 may not be able to generate aerosol immediately. However, since there is a certain amount of atomizing medium in the vent hole 120 at this time, the atomizing medium in the vent hole 120 can also be atomized to form a certain amount of aerosol immediately to supply the user with inhalation, ensuring a better user experience;

[0084] Fourthly, compared with methods such as separately adding a sensor airway outside the base 100 for detecting airflow changes, the solution of the present application directly sets the vent 120 on the base 100. On the one hand, the process and structure are simpler, which can reduce the manufacturing difficulty and manufacturing cost. On the other hand, there is no need to add other additional components, which undoubtedly saves the internal space of the product, is conducive to the simplification and miniaturization of the product, and is more popular with users.
