Description

Technical Field

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

[0002] Aerosol generating devices typically include an atomizer and a power supply component electrically connected to the atomizer. Under the electric drive of the power supply component, the atomizer can atomize the aerosol generating matrix stored in the liquid storage chamber using various methods such as ultrasonic atomization, resistance atomization, electromagnetic atomization, and heating without combustion to form an aerosol for user use.

[0003] In related technologies, the amount of aerosol generating matrix entering the atomizing component during inhalation needs to be appropriate. Too much aerosol generating matrix can lead to leakage, while too little can result in insufficient aerosol concentration, both affecting the inhalation experience. Furthermore, these technologies suffer from significant differences in taste. Utility Model Content

[0004] In view of this, the present application aims to provide an atomizer and aerosol generating device that can improve leakage and also address the problem of significant differences in taste.

[0005] Therefore, a first aspect of the embodiments of this application provides an atomizer, the atomizer comprising:

[0006] The liquid storage chamber is used to store the aerosol generation matrix;

[0007] An atomizing component is used to atomize an aerosol generating matrix; the atomizing component includes an atomizing core and a liquid guiding component that can conduct the aerosol generating matrix, the liquid guiding component being in communication with the liquid storage chamber.

[0008] A ventilation channel, one end of which is connected to the liquid storage chamber, and the other end of which is connected to the outside of the atomizer;

[0009] The buffer section, the atomizer includes a first state and a second state, the ventilation pressure of the ventilation channel in the first state is less than the ventilation pressure in the second state; and when the atomizer is in the first state, at least a portion of the aerosol generating matrix flows to the buffer section via the atomizing component and / or the liquid storage chamber.

[0010] In some embodiments, in the first state, the ventilation pressure of the ventilation channel is in the range of -500 Pa to -200 Pa; and / or,

[0011] In the second state, the ventilation pressure of the ventilation channel is in the range of -1000pa to -600pa.

[0012] In some embodiments, in the first state, the ratio of the total volume of the aerosol generating matrix in the storage cavity to the volume of the storage cavity is less than 0.5; in the second state, the ratio of the total volume of the aerosol generating matrix in the storage cavity to the volume of the storage cavity is in the range of 0.5 to 1.

[0013] In some embodiments, the liquid guiding element includes a first liquid guiding element that is in liquid communication with the liquid storage chamber; the buffer includes a first liquid storage element that is at least partially in contact with the first liquid guiding element, and in the first state of the atomizer, at least a portion of the aerosol generating matrix flows through the first liquid guiding element to the first liquid storage element.

[0014] In some embodiments, the liquid guiding capacity of the first liquid guiding element is greater than that of the first liquid storage element.

[0015] In some embodiments, the liquid guiding component further includes a second liquid guiding component, which is sleeved on the periphery of the first liquid guiding component. The aerosol generating matrix in the liquid storage cavity is connected to the first liquid guiding component through the second liquid guiding component, and the liquid guiding capacity of the first liquid guiding component is greater than that of the second liquid guiding component.

[0016] In some embodiments, the atomizer further includes a mounting base, the atomizing component is disposed on the mounting base, and the buffer includes a buffer cavity formed in the mounting base.

[0017] In some embodiments, the buffer chamber includes a first buffer chamber, the mounting base includes an atomizing seat and a partition wall, the atomizing seat is provided with an installation space, the partition wall is disposed within the installation space and divides the installation space to form an installation chamber and the first buffer chamber, and the atomizing component is disposed in the installation chamber; when the atomizer is in a first state, at least a portion of the aerosol generating matrix is ​​buffered in the first buffer chamber via the liquid storage chamber.

[0018] In some embodiments, the cavity wall of the first buffer cavity forms a third capillary channel, at least one end of the third capillary channel extends toward the bottom wall of the first buffer cavity, and the other end is in liquid communication with the liquid storage cavity and / or the liquid guiding element.

[0019] A second aspect of this application provides an aerosol generating apparatus, including a power supply component and the atomizer described above, wherein the power supply component is electrically connected to the atomizing core.

[0020] This application provides an atomizer. The atomizing component of the atomizer includes an atomizing core and a liquid guiding component that can conduct aerosol generating matrix. The liquid guiding component can guide the aerosol generating matrix to the atomizing core, so that the atomizing core can generate aerosol by atomizing the aerosol generating matrix. As the aerosol generating matrix in the storage chamber gradually decreases during the inhalation process, the ventilation pressure in the ventilation channel in the first state is lower than the ventilation pressure in the second state. Thus, on the one hand, in the second state where the ventilation pressure is relatively high, the liquid guiding component itself can supply liquid to the atomizing core through its liquid locking, liquid guiding, and liquid storage capabilities. By controlling the aerosol generating matrix consumed per puff to match the inhalation time and / or inhalation power, it is beneficial to improve the consistency of flavor and thus improve the problem of large differences in flavor. On the other hand, by setting up a buffer section, in the first state where the ventilation pressure is relatively low, at least a portion of the aerosol generation matrix flows to the buffer section through the atomizing component and / or the liquid storage chamber. This reduces the difference in liquid supply to the atomizing core between the first and second states, further improving the problem of significant differences in taste. In addition, it can also improve the problem of leakage caused by the reduced ventilation pressure. In other words, the atomizer of this application embodiment can improve both leakage and taste consistency. Attached Figure Description

[0028] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0029] In the description of the embodiments in this application, it should be noted that the terms "top," "bottom," etc., indicate the orientation or positional relationship based on the appendix. Figure 2 The orientations or positional relationships shown are for the convenience of describing the embodiments of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. The application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] One aspect of this application provides an aerosol generating apparatus; please refer to [link to relevant documentation]. Figures 1 to 3 The aerosol generating device includes a power supply assembly and an atomizer 100 provided in any embodiment of this application. The power supply assembly is electrically connected to the atomizing core 13.

[0031] One aspect of this application provides an atomizer 100; please refer to... Figures 1 to 5 The atomizer 100 includes a liquid storage chamber 50, an atomizing component 10, a ventilation channel, and a buffer section 20. The liquid storage chamber 50 stores the aerosol generation matrix. The atomizing component 10 atomizes the aerosol generation matrix. The atomizing component 10 includes an atomizing core 13 and a liquid guide that conducts the aerosol generation matrix; the liquid guide is in liquid communication with the liquid storage chamber 50. One end of the ventilation channel is connected to the liquid storage chamber 50, and the other end is connected to the outside of the atomizer 100. The atomizer 100 includes a first state and a second state, wherein the ventilation pressure in the ventilation channel in the first state is lower than the ventilation pressure in the second state. When the atomizer 100 is in the first state, at least a portion of the aerosol generation matrix flows through the atomizing component 10 and / or the liquid storage chamber 50 to the buffer section 20.

[0032] In some embodiments, the atomizer 100 and the power supply assembly can be mechanically and electrically connected together axially. Further, the atomizer 100 and the power supply assembly can be connected together in a detachable manner using magnetic connections, threaded connections, snap-fit ​​connections, or other similar methods. Both the atomizer 100 and the power supply assembly can be replaced or upgraded individually, reducing replacement costs and saving user expenses. Of course, in other embodiments, the atomizer 100 and the power supply assembly can also be connected together in a non-detachable manner.

[0033] Furthermore, the atomizer 100 and / or power supply assembly are not limited to being cylindrical; they can also be other shapes such as elliptical cylinders, square boxes, or polygonal cylinders. For example, in this embodiment, the cross-section at the lower end of the atomizer 100 is approximately elliptical, while the cross-section at the upper part of the atomizer 100 is approximately flat.

[0034] It should be noted that the specific type of aerosol generating device provided in the embodiments of this application is not limited. For example, the aerosol generating device can be a medical atomizing device, an air humidifier, or an atomizing device such as an electronic cigarette.

[0035] For example, please refer to Figures 1 to 3 The atomizer 100 also includes an air outlet channel 40, which is used to discharge the aerosol generated by the atomization of the atomization component 10.

[0036] Here, the liquid guiding component is in liquid communication with the liquid storage chamber 50. The aerosol generating matrix in the liquid storage chamber 50 can be guided to the liquid guiding component, that is, the liquid guiding component is used to absorb the aerosol generating matrix. The atomizing core 13 atomizes the aerosol generating matrix and generates aerosol.

[0037] For example, please refer to Figures 2 to 3 The atomizer 100 also includes a liquid inlet channel 60, one end of which is connected to the liquid storage chamber 50, and the other end is connected to the liquid guide component. In other words, the aerosol generating matrix in the liquid storage chamber 50 can be guided to the liquid guide component through the liquid inlet channel 60.

[0038] For example, the liquid guide has a channel inside, and the atomizing core 13 is disposed in the channel so that the atomizing core 13 can heat and atomize the aerosol generation matrix on the inner wall of the channel. The channel is connected to the air outlet channel 40. The generated aerosol mixes with the air entering the channel and then enters the air outlet channel 40 for user use.

[0039] For example, the centerline of the channel is approximately or completely coincident with the centerline of the air outlet channel 40, and the channel and the air outlet channel 40 are directly connected. The aerosol generated by atomization does not need to go through bends to finally reach the user. As a result, aerosol loss can be reduced and the flavor explosion can be improved.

[0040] For example, the atomizing core 13 includes a heating element that generates heat to heat and atomize the aerosol generating matrix.

[0041] It should be noted that the specific structure of the heating element is not limited here. The heating element includes, but is not limited to, heating elements such as heating plates, heating films, and heating meshes.

[0042] The specific shape of the heating element is not limited here. The heating element may be flat, cylindrical, or bowl-shaped.

[0043] For example, the atomizing core 13 includes a finished core.

[0044] The aerosol generating matrix in the liquid storage chamber 50 is guided to the atomizing component 10 for atomization to generate aerosol. After the aerosol generating matrix in the liquid storage chamber 50 is consumed, external gas enters the liquid storage chamber 50 through the ventilation channel to balance the pressure in the liquid storage chamber 50.

[0045] The ventilation pressure of the ventilation channel refers to the ventilation resistance that the gas needs to overcome to enter the liquid storage chamber 50. The higher the ventilation pressure of the ventilation channel, the greater the corresponding suction resistance, and correspondingly, the amount of liquid flowing out of the liquid storage chamber 50 is relatively reduced, that is, the amount of aerosol-generating matrix flowing out of the liquid storage chamber 50 is also relatively reduced. The lower the ventilation pressure of the ventilation channel, the lower the corresponding suction resistance, and correspondingly, the amount of liquid flowing out of the liquid storage chamber 50 is relatively increased, that is, the amount of aerosol-generating matrix flowing out of the liquid storage chamber 50 is also relatively increased.

[0046] Here, there are many factors that affect the ventilation pressure of the ventilation channel, such as the content of the aerosol generating matrix in the liquid storage chamber 50, the type of aerosol generating matrix, and the usage scenario of the aerosol generating device, all of which may affect the ventilation pressure of the ventilation channel.

[0047] The phrase "at least a portion of the aerosol generating matrix is ​​buffered in the buffer section 20 via the atomizing component 10 and / or the storage chamber 50" means that at least a portion of the aerosol generating matrix is ​​buffered in the buffer section 20 via the atomizing component 10, at least a portion of the aerosol generating matrix is ​​buffered in the buffer section 20 via the storage chamber 50, or at least a portion of the aerosol generating matrix is ​​buffered in the buffer section 20 via both the atomizing component 10 and the storage chamber 50.

[0048] In other words, under the first state where the ventilation pressure is relatively low, the buffer section 20 buffers excess aerosol generation matrix, which helps to improve the leakage of aerosol generation matrix.

[0049] In related technologies, as the aerosol generation matrix in the storage chamber gradually decreases during the suction process, a relative increase in the amount of liquid flowing into the storage chamber may lead to leakage. Conversely, a relative decrease in the amount of liquid flowing into the storage chamber helps to improve the leakage problem, but at the same time, it may result in a drier smoke and poorer consistency in taste.

[0050] This application provides an atomizer 100. The atomizing component 10 of the atomizer 100 includes an atomizing core 13 and a liquid guide that can conduct aerosol generating matrix. The liquid guide can guide the aerosol generating matrix to the atomizing core 13, so that the atomizing core 13 can generate aerosol through atomizing the aerosol generating matrix. As the aerosol generating matrix in the storage chamber 50 gradually decreases during the inhalation process, the ventilation pressure in the ventilation channel in the first state is lower than the ventilation pressure in the second state. Thus, on the one hand, in the second state where the ventilation pressure is relatively high, the liquid guide can supply liquid to the atomizing core 13 through its own liquid locking, liquid guiding, and liquid storage capabilities. By controlling the aerosol generating matrix consumed per inhalation to match the inhalation time and / or inhalation power, it is beneficial to improve the consistency of taste, thereby improving the problem of large taste differences. On the other hand, by providing a buffer section 20, in the first state where the ventilation pressure is relatively low, at least a portion of the aerosol generation matrix flows through the atomizing component 10 and / or the liquid storage chamber 50 to the buffer section 20. This reduces the difference in liquid supply to the atomizing core between the first and second states, further improving the problem of significant differences in taste. Furthermore, it also improves the problem of leakage caused by reduced ventilation pressure. In other words, the atomizer 100 of this embodiment can improve both leakage and taste consistency. Additionally, the atomizer 100 has a simple structure and low cost.

[0051] In some embodiments, in the second state, the ventilation pressure of the ventilation passage is in the range of -1000pa to -600pa.

[0052] The ventilation pressure of the ventilation channel can be any one of -1000pa, -990pa, -970pa, -950pa, -900pa, -880pa, -850pa, -830pa, -800pa, -780pa, -750pa, -700pa, -680pa, -650pa, -630pa, or -600pa, or any value between two of them.

[0053] In this embodiment, by setting the air exchange pressure of the air exchange channel of the atomizer 100 in the second state to be in the range of -1000pa to -600pa, the liquid can be supplied to the atomizing core 13 through the liquid locking, liquid guiding and liquid storage capacity of the liquid guiding component itself. By controlling the aerosol generation matrix consumed for each puff to match the puffing time and / or puffing power, it is beneficial to improve the consistency of taste, thereby improving the problem of large taste differences.

[0054] In some embodiments, in the first state, the ventilation pressure of the ventilation passage is in the range of -500 Pa to -200 Pa.

[0055] The ventilation pressure of the ventilation channel can be any one of -500pa, -480pa, -460pa, -450pa, -410pa, -400pa, -380pa, -370pa, -350pa, -320pa, -300pa, -290pa, -270pa, -260pa, -250pa, -200pa, or any value between two of them.

[0056] In this embodiment, by setting the ventilation pressure of the ventilation channel of the atomizer 100 in the first state to be in the range of -500pa to -200pa, and by cooperating with the buffer unit 20, at least a portion of the aerosol generation matrix is ​​buffered in the buffer unit 20 via the atomizing component 10 and / or the liquid storage chamber 50, so as to reduce the difference in liquid supply between the first state and the second state of the liquid guide, which is more conducive to improving the problem of large differences in taste. In addition, it can also improve the problem of leakage caused by the reduction of ventilation pressure.

[0057] In some embodiments, in a first state, the ratio of the total volume of the aerosol-generating matrix in the reservoir 50 to the volume of the reservoir 50 is less than 0.5. In a second state, the ratio of the total volume of the aerosol-generating matrix in the reservoir 50 to the volume of the reservoir 50 is in the range of 0.5 to 1.

[0058] In other words, the first and second states can be determined by the amount of aerosol generating matrix in the storage chamber. At a high liquid level, that is, when the ratio of the total volume of the aerosol generating matrix in the storage chamber 50 to the volume of the storage chamber 50 is in the range of 0.5 to 1, the ventilation pressure is relatively high, and the amount of aerosol generating matrix drawn out of the storage chamber 50 is just enough for one suction. At a low liquid level, that is, when the ratio of the total volume of the aerosol generating matrix in the storage chamber 50 to the volume of the storage chamber 50 is less than 0.5, the ventilation pressure is relatively low, and the amount of aerosol generating matrix drawn out of the storage chamber 50 is greater than the amount drawn in one suction. At this time, the excess aerosol generating matrix flows to the buffer section through the atomizing component and / or the storage chamber.

[0059] It can be understood that the greater the content of aerosol generating matrix in the storage chamber 50, the greater the gas exchange resistance that the gas needs to overcome to enter the storage chamber 50. For example, the ratio of the total volume of aerosol generating matrix in the storage chamber 50 to the volume of the storage chamber 50 is in the range of 0.5 to 1. Conversely, the less the content of aerosol generating matrix in the storage chamber 50, the smaller the gas exchange resistance that the gas needs to overcome to enter the storage chamber 50. For example, the ratio of the total volume of aerosol generating matrix in the storage chamber 50 to the volume of the storage chamber 50 is in the range of 0.5 to 1.

[0060] For example, when the ratio of the total volume of the aerosol generation matrix in the liquid storage chamber 50 to the volume of the liquid storage chamber 50 is less than 0.5, the corresponding air exchange pressure of the air exchange channel is in the range of -500pa to -200pa. At this time, the atomizer 100 is in the first state.

[0061] For example, when the ratio of the total volume of the aerosol generation matrix in the storage chamber 50 to the volume of the storage chamber 50 is in the range of 0.5 to 1, the corresponding ventilation pressure of the ventilation channel is in the range of -1000pa to -600pa, and at this time, the atomizer 100 is in the second state.

[0062] In this embodiment, by considering the ratio of the total volume of the aerosol-generating matrix in the storage chamber 50 to the volume of the storage chamber 50, that is, by considering the change in the content of the aerosol-generating matrix in the storage chamber 50 with use, the liquid-locking, liquid-guiding, and liquid-storing capabilities of the liquid guide component are correspondingly set to supply liquid to the atomizing core 13. Furthermore, by controlling the aerosol-generating matrix consumed per puff to match the puffing time and / or puffing power, it is beneficial to further improve the consistency of flavor, thereby mitigating the problem of significant flavor differences. In addition, by combining this with the use of the buffer unit 20, the atomizer 100 can further improve flavor consistency while simultaneously reducing leakage.

[0063] Of course, the application scenario of the aerosol generation device may also affect the pressure of the storage chamber. For example, when the ambient temperature rises, the air expands due to heat, increasing the pressure in the storage chamber 50. At least a portion of the aerosol generation matrix is ​​buffered in the buffer section 20 via the atomizing component 10 and / or the storage chamber 50. When the ambient temperature decreases, the air contracts due to cold, reducing the pressure in the storage chamber 50. This allows the aerosol generation matrix on the buffer section 20 to be drawn back into the storage chamber 50, thus maintaining the pressure balance in the storage chamber 50 and ensuring that the liquid guide adsorbs sufficient aerosol generation matrix. Furthermore, the system can still operate stably when the external air pressure changes, especially when the external air pressure is lower than atmospheric pressure, such as in high-altitude or high-altitude environments. In such cases, the external air pressure is lower than the air pressure inside the storage chamber 50, causing the aerosol generation matrix inside the storage chamber 50 to flow out under the pressure difference. The outflowing aerosol generation matrix is ​​then buffered in the buffer section 20, thus maintaining the pressure balance in the storage chamber 50.

[0064] In some embodiments, please refer to Figures 2 to 3 The liquid guiding component includes a first liquid guiding component 11, which is in liquid communication with the liquid storage chamber 50. The buffer unit 20 includes a first liquid storage component 21, which is at least partially in contact with the first liquid guiding component 11. When the atomizer 100 is in a first state, at least a portion of the aerosol generation matrix flows through the first liquid guiding component 11 to the first liquid storage component 21.

[0065] In other words, the first liquid guiding component 11 has a channel inside, and the atomizing core 13 is disposed in the channel of the first liquid guiding component 11.

[0066] There are multiple ways for the first liquid storage component 21 and the first liquid guiding component 11 to contact each other. For example, the first liquid storage component 21 and the first liquid guiding component 11 can contact each other at the end face, at the side (inner side or outer side), or at both the end face and the side (inner side or outer side).

[0067] The first liquid storage component 21 is at least partially in contact with the first liquid guiding component 11. When there is too much aerosol generating matrix on the first liquid guiding component 11, that is, when the supply of aerosol generating matrix increases under the same usage conditions, the excess aerosol generating matrix will be guided to the first liquid storage component 21 through the first liquid guiding component 11. In this way, the aerosol generating matrix flowing to the atomizing component 10 can be matched with the aerosol generating matrix that needs to be consumed, thereby helping to improve the situation of suction leakage.

[0068] For example, when the atomizer 100 is in the second state, at the start of inhalation, the first liquid guide 11 is in a relatively saturated state (e.g., saturation of about 80%), and the first liquid reservoir 21 is not wetted by aerosol generating matrix, or there is a small amount of aerosol generating matrix and the relative saturation is low. At this time, the aerosol generating matrix flowing through the first liquid guide 11 to the atomizing component 10 matches the aerosol generating matrix that needs to be consumed, thereby helping to improve the consistency of taste. As suction is applied, the content of aerosol generating matrix in the storage chamber 50 decreases, or other reasons cause the ventilation pressure in the ventilation channel to drop to the range of the first state. At this time, the aerosol generating matrix flowing to the atomizing component 10 through the first liquid guide 11 is more than the aerosol generating matrix that needs to be consumed. By setting the first liquid storage component 21 at one end of the first liquid guide 11, the excess aerosol generating matrix will be guided to the first liquid storage component 21 through the first liquid guide 11, so that the aerosol generating matrix flowing to the atomizing component 10 matches the aerosol generating matrix that needs to be consumed, thereby helping to improve the situation of suction leakage. Furthermore, when the aerosol generating matrix in the storage chamber 50 is depleted, or when the amount of aerosol generating matrix flowing from the first liquid guide 11 to the atomizing component 10 is less than the amount of aerosol generating matrix that needs to be consumed due to the reduction of the aerosol generating matrix in the storage chamber 50, the aerosol generating matrix stored in the first liquid storage 21 will also be guided to the first liquid guide 11 under capillary action and / or gravity to achieve the reuse of the aerosol generating matrix, thereby improving the utilization rate of the aerosol generating matrix and improving the problem of waste of leaked aerosol generating matrix.

[0069] In other embodiments, at least a portion of the aerosol generating matrix may flow through the storage chamber 50 to the first storage element 21.

[0070] In some embodiments, please refer to Figures 2 to 3 The first liquid guiding component 11 has a greater liquid guiding capacity than the first liquid storage component 21.

[0071] For example, the density of the first liquid guiding element 11 is greater than the density of the first liquid storage element 21.

[0072] In this way, the liquid storage capacity of the first liquid guiding component 11 is weaker than that of the first liquid storage component 21.

[0073] In this embodiment, by making the liquid guiding capacity of the first liquid guiding component 11 greater than that of the first liquid storage component 21, on the one hand, it is beneficial to improve the liquid supply efficiency of the first liquid guiding component 11, and it can also improve the situation where the first liquid storage component 21 adsorbs the aerosol in the first liquid guiding component 11 to form a matrix when the atomizer 100 is in the second state, thereby improving the liquid supply reliability of the first liquid guiding component 11. On the other hand, it can also make the liquid storage capacity of the first liquid storage component 21 stronger than that of the first liquid guiding component 11, thus improving the situation where the atomizer 100 draws liquid leakage when in the first state.

[0074] In some embodiments, please refer to Figures 2 to 3 The first liquid storage component 21 is disposed above the first liquid guiding component 11.

[0075] In other words, the first liquid storage component 21 abuts against the top of the first liquid guiding component 11.

[0076] In this embodiment, by placing the first liquid storage component 21 above the first liquid guiding component 11, the atomizer 100 in the first state is further facilitated by the aerosol generating matrix stored in the first liquid storage component 21 being guided to the first liquid guiding component 11 under capillary action and gravity, so as to realize the reuse of the aerosol generating matrix.

[0077] In some embodiments, please refer to Figures 2 to 3 The liquid guiding component also includes a second liquid guiding component 12, which is sleeved on the periphery of the first liquid guiding component 11. The aerosol generating matrix in the liquid storage cavity 50 is connected to the first liquid guiding component 11 through the second liquid guiding component 12. The liquid guiding capacity of the first liquid guiding component 11 is greater than that of the second liquid guiding component 12.

[0078] For example, the density of the first liquid guiding element 11 is greater than the density of the second liquid guiding element 12.

[0079] In other words, the liquid guiding component includes a first liquid guiding component 11 and a second liquid guiding component 12. The aerosol generating matrix in the liquid storage chamber 50 flows sequentially through the second liquid guiding component 12 and the first liquid guiding component 11, and then provides the aerosol generating matrix to the heating component through the first liquid guiding component 11.

[0080] Here, the second liquid guiding element 12 is sleeved on the periphery of the first liquid guiding element 11, that is, the second liquid guiding element 12 is arranged radially along the first liquid guiding element 11.

[0081] The density of the first liquid guiding component 11 is greater than that of the second liquid guiding component 12, so that the liquid guiding capacity of the first liquid guiding component 11 is stronger than that of the second liquid guiding component 12.

[0082] In this embodiment, by setting the liquid guiding component to include a first liquid guiding component 11 and a second liquid guiding component 12, i.e. by graded liquid guiding, the flow resistance of the aerosol generation matrix is ​​increased, which is beneficial to improving the situation of liquid leakage during suction.

[0083] In some embodiments, the first liquid guiding member 11 and the second liquid guiding member 12 are separate structures. In other embodiments, the first liquid guiding member 11 and the second liquid guiding member 12 are an integral structure.

[0084] In some embodiments, please refer to Figures 2 to 3 The first liquid guiding element 11 has a first capillary channel, and the second liquid guiding element 12 has a second capillary channel. The first capillary channel extends along the height direction of the atomizer 100, and the extension direction of the second capillary channel is perpendicular to the height direction of the atomizer 100.

[0085] For example, the first capillary channel extends axially along the first liquid guiding element 11, and the second capillary channel extends radially along the first liquid guiding element 11.

[0086] For example, the second liquid guiding element 12 adopts a transverse fiber structure so that the second capillary channel extends radially along the first liquid guiding element 11, which is beneficial to increasing the flow rate of the aerosol generating matrix in the second liquid guiding element 12 along the radial direction of the first liquid guiding element 11.

[0087] For example, the first liquid guiding element 11 adopts a vertical fiber structure so that the first capillary channel extends along the axial direction of the first liquid guiding element 11, which is beneficial to increasing the flow rate of the aerosol generating matrix along the axial direction of the first liquid guiding element 11, thereby improving the liquid supply range of the liquid guiding element.

[0088] For example, the first liquid storage component 21 adopts a vertical fiber structure so that the capillary channel of the first liquid storage component 21 extends along the axial direction of the first liquid storage component 21, which is beneficial to improve the flow of the aerosol generation matrix between the first liquid storage component 21 and the first liquid guiding component 11, thereby improving the liquid storage capacity of the first liquid storage component 21.

[0089] In some embodiments, the density of the first liquid guiding element 11 is 0.1 g / cm³. 3 Up to 0.12 g / cm 3 The range.

[0090] The density of the first liquid guiding element 11 can be 0.1 g / cm³. 3 0.105g / cm 3 0.11 g / cm 3 0.115g / cm 3 0.12g / cm 3 The point value of any one of them or the point value between any two.

[0091] In this embodiment, the density of the first liquid guiding element 11 is set to 0.1 g / cm³. 3 Up to 0.12 g / cm 3 The density within this range is appropriate so that the first liquid guiding component 11 has a certain liquid locking ability, liquid guiding ability and liquid storage ability, and can make the aerosol generating matrix flowing from the first liquid guiding component 11 to the atomizing component 10 match the aerosol generating matrix consumed per suction, the suction time and the suction power.

[0092] In some embodiments, the density of the second liquid guiding element 12 is 0.07 g / cm³. 3 Up to 0.09 g / cm 3 The range.

[0093] The density of the second liquid guiding element 12 can be 0.07 g / cm³. 3 0.075g / cm 3 0.08g / cm 3 0.085g / cm 3 0.09g / cm 3 The point value of any one of them or the point value between any two.

[0094] In this embodiment, the density of the second liquid guiding element 12 is set to 0.07 g / cm³. 3 Up to 0.09 g / cm 3 The appropriate density within this range is beneficial for achieving graded liquid guidance, increasing the flow resistance of the aerosol generation matrix, and also for increasing the radial flow velocity of the aerosol generation matrix in the second liquid guiding component 12 along the first liquid guiding component 11.

[0095] In some embodiments, the density of the first liquid reservoir 21 is 0.06 g / cm³. 3 Up to 0.07 g / cm 3 The range.

[0096] The density of the first liquid storage component 21 can be 0.06 g / cm³. 3 0.065g / cm 3 0.07g / cm 3 The point value of any one of them or the point value between any two.

[0097] In this embodiment, the density of the first liquid storage element 21 is set to 0.06 g / cm³. 3 Up to 0.07 g / cm 3 The appropriate density within this range is beneficial for achieving graded liquid guidance, increasing the flow resistance of the aerosol generation matrix, and also for increasing the radial flow velocity of the aerosol generation matrix in the second liquid guiding component 12 along the first liquid guiding component 11.

[0098] In some embodiments, please refer to Figures 2 to 5 The atomizer 100 also includes a mounting base 30, the atomizing component 10 is disposed on the mounting base 30, and the buffer section 20 includes a buffer cavity formed in the mounting base 30.

[0099] For example, the atomizer 100 includes a housing 70, the interior of which has a receiving area.

[0100] For example, at least a portion of the mounting base 30 is disposed in the receiving area, and the mounting base 30 together with the housing 70 defines the liquid storage chamber 50.

[0101] Of course, in other embodiments, the housing 70 may form the liquid storage cavity 50.

[0102] For example, the air outlet channel 40 may be formed in the housing 70, or the mounting base 30 and the housing 70 may jointly form the air outlet channel 40.

[0103] In this embodiment, the buffer unit 20 is provided with a buffer cavity so that at least part of the aerosol generating matrix is ​​buffered into the buffer cavity via the atomizing component 10 and / or the liquid storage cavity 50. The provision of the buffer cavity is beneficial to increasing the buffering capacity of the aerosol generating matrix, thereby further improving the leakage problem.

[0104] In some embodiments, please refer to Figures 2 to 3 The buffer chamber includes a first buffer chamber 23, and the mounting base 30 includes an atomizing seat 31 and a partition wall 32. The atomizing seat 31 is provided with an installation space, and the partition wall 32 is disposed within the installation space, dividing the installation space into an installation chamber 313 and the first buffer chamber 23. The atomizing component 10 is disposed in the installation chamber 313. When the atomizer 100 is in a first state, at least a portion of the aerosol generation matrix is ​​buffered in the first buffer chamber 23 via the liquid storage chamber 50.

[0105] For example, the atomizing base 31 includes an upper atomizing base 311 and a lower atomizing base 312, with an installation space defined between the upper atomizing base 311 and the lower atomizing base 312.

[0106] Here, the upper atomizer 311 and the lower atomizer 312 can be either separate or integrated.

[0107] Here, the materials of the atomizing upper base 311 and the atomizing lower base 312 can be the same or different.

[0108] In some embodiments, the atomizing base 312 may be made of injection molded material or rubber material.

[0109] In some embodiments, the atomizing seat 31 is provided with a liquid inlet channel 60, which is connected to the liquid storage chamber 50.

[0110] Specifically, the atomizing seat 31 is provided with a liquid inlet column, and the inside of the liquid inlet column has a liquid inlet channel 60. The liquid inlet column extends into the liquid storage chamber 50 to realize the connection between the liquid inlet channel 60 and the liquid storage chamber 50.

[0111] In other embodiments, the housing 70 and the atomizing seat 31 may together form the liquid inlet channel 60.

[0112] For example, a first buffer cavity 23 is defined between the partition wall 32 and the side wall of the installation space.

[0113] Here, the number of first buffer cavities 23 can be one or more.

[0114] In the embodiments of this application, "multiple" refers to two or more items.

[0115] For example, the first buffer cavity 23 may be in liquid communication with the liquid storage cavity 50, or in liquid communication with the liquid inlet channel 60, or in liquid communication with the liquid guide, or in liquid communication with at least two of the liquid storage cavity 50, the liquid inlet channel 60, and the liquid guide simultaneously.

[0116] For example, the sidewall of the installation space is formed with capillary channels, and the first buffer cavity 23 is connected to the liquid inlet channel 60 through the capillary channels.

[0117] In this embodiment, by setting a partition wall 32, the installation space is divided into an installation cavity 313 and a first buffer cavity 23. As suction is performed, the content of aerosol generating matrix in the liquid storage cavity 50 decreases, or other reasons cause the ventilation pressure of the ventilation channel to drop to the range of the first state. At this time, the aerosol generating matrix in the liquid storage cavity 50 will be buffered in the first buffer cavity 23, which helps to improve the situation of suction leakage.

[0118] Furthermore, in the embodiment with the first liquid storage component 21, as suction occurs, the content of aerosol generating matrix in the liquid storage chamber 50 decreases, or the ventilation pressure of the ventilation channel decreases to the range of the first state due to other reasons. At this time, the aerosol generating matrix flowing to the atomizing component 10 through the first liquid guide component 11 is more than the aerosol generating matrix that needs to be consumed. By setting the first liquid storage component 21 at one end of the first liquid guide component 11, the excess aerosol generating matrix will be guided to the first liquid storage component 21 through the first liquid guide component 11. After storing a certain amount of aerosol generating matrix in the first liquid storage component 21, the excess aerosol generating matrix can be further buffered in the first buffer chamber 23, which is beneficial to increasing the buffer capacity of aerosol generating matrix.

[0119] In some embodiments, please refer to Figures 1 to 3 The cavity wall of the first buffer cavity 23 forms a third capillary channel 25. At least one end of the third capillary channel 25 extends toward the bottom wall of the first buffer cavity 23, and the other end is in liquid communication with the liquid storage cavity 50 and / or the liquid guiding element.

[0120] Here, the third capillary channel 25 can be in liquid communication with the liquid storage chamber 50, or in liquid communication with the liquid guiding component, or both the liquid storage chamber 50 and the liquid guiding component can be in liquid communication.

[0121] In this embodiment, when the aerosol generating matrix in the storage chamber 50 is consumed, or when the aerosol generating matrix in the storage chamber 50 decreases, resulting in less aerosol generating matrix flowing from the first liquid guide 11 to the atomizing component 10 than the required aerosol generating matrix, the cavity wall of the first buffer chamber 23 is provided with a third capillary channel 25. The aerosol generating matrix stored in the first buffer chamber 23 can be guided to the storage chamber 50 and / or the liquid guide under the capillary action of the third capillary channel 25, so as to realize the reuse of the aerosol generating matrix, thereby improving the utilization rate of the aerosol generating matrix and improving the problem of waste of leaked aerosol generating matrix.

[0122] It should be noted that the specific structure of the ventilation channel is not limited here.

[0123] For example, the gap between the first liquid guide 11 and the atomizing seat 31 and / or the gap inside the first liquid guide 11 form an air exchange channel.

[0124] For example, the gap between the second liquid guide 12 and the atomizing seat 31 and / or the gap inside the second liquid guide 12 form a ventilation channel.

[0125] For example, the gap between the first liquid guide 11 and the atomizing seat 31 and / or the gap inside the first liquid guide 11, the gap between the second liquid guide 12 and the atomizing seat 31 and / or the gap inside the second liquid guide 12 form an air exchange channel.

[0126] For example, the gap between the first liquid guide 11 and the atomizing seat 31 and / or the gap inside the first liquid guide 11, the gap between the first liquid storage component 21 and the atomizing seat 31 and / or the gap inside the first liquid storage component 21 form a ventilation channel.

[0127] For example, the gap between the first liquid guide 11 and the atomizing seat 31 and / or the gap inside the first liquid guide 11, the gap between the second liquid guide 12 and the atomizing seat 31 and / or the gap inside the second liquid guide 12, the gap between the first liquid storage component 21 and the atomizing seat 31 and / or the gap inside the first liquid storage component 21 form a ventilation channel.

[0128] In some embodiments, please refer to Figures 1 to 3 The mounting base 30 includes an atomizing base 31, which has a mounting cavity 313. The atomizing component 10 is disposed in the mounting cavity 313. A portion of the cavity wall of the mounting cavity 313 is recessed to form a ventilation groove 314, which defines at least a portion of the ventilation channel between the ventilation groove 314 and the liquid guiding component.

[0129] For example, please refer to Figures 4 to 5 The atomizing base 312 is equipped with an air exchange slot 314.

[0130] For example, the width of the ventilation groove 314 is greater than 1.2 mm, and the height of the ventilation groove 314 is greater than or equal to 1 mm.

[0131] Here, the material of the atomizing seat 31 is generally a non-cotton material. Therefore, by forming an air exchange groove 314 by recessing part of the cavity wall of the mounting cavity 313, it is beneficial to improve the stability of the air exchange channel and improve the dimensional changes of the air exchange channel caused by assembly errors, production errors or stress, thereby improving the air exchange stability.

[0132] In this embodiment, a ventilation groove 314 is formed by recessing part of the cavity wall of the mounting cavity 313 to form a stable ventilation channel, which is beneficial to improving ventilation stability, thereby improving the stability of liquid supply.

[0133] For example, the atomizing assembly 10 also includes a mounting member 14, a heating member disposed inside the mounting member 14, and a liquid guiding member sleeved around the periphery of the mounting member 14.

[0134] For example, mounting component 14 may be a mounting tube.

[0135] For example, the mounting component 14 forms a liquid passage. Here, the number of liquid passages can be one or more.

[0136] For example, the atomizing component 10 further includes a third liquid guiding component, which has a channel, a heating component disposed in the channel, and the third liquid guiding component is disposed in the mounting component 14. The aerosol generating matrix of the first liquid guiding component 11 is guided to the third liquid guiding component through the liquid outlet, and the heating component atomizes the aerosol generating matrix of the third liquid guiding component.

[0137] For example, the sidewall of the mounting member 14 is formed with a ventilation hole 141, which is connected to the ventilation groove 314.

[0138] For example, the diameter of the vent 141 is approximately 0.3 mm.

[0139] In some embodiments, please refer to Figures 2 to 3 The liquid guiding component has a channel, and the atomizing core 13 is disposed in the channel. The buffer chamber includes a second buffer chamber 24. The mounting base 30 includes an atomizing base 31 and a bottom cover 315. The bottom cover 315 is connected to the bottom of the atomizing base 31 and defines the second buffer chamber 24 between the bottom cover 315 and the atomizing base 31. When the atomizer 100 is in the first state, at least a portion of the aerosol generating matrix flows to the second buffer chamber 24 through the channel.

[0140] For example, when the atomizer 100 is in the first state (e.g., the ambient temperature rises), the pressure in the liquid storage chamber 50 increases, and at least a portion of the aerosol generation matrix flows through the channel to the second buffer chamber 24.

[0141] In embodiments where a first liquid storage element 21 is provided, if the first liquid storage element 21 cannot store more aerosol generating matrix, excess aerosol generating matrix may flow out from the heating element and / or the first liquid guiding element 11 and then flow to the second buffer chamber 24, which helps to improve the situation where aerosol generating matrix leaks onto the product surface.

[0142] In some embodiments, please refer to Figures 2 to 3 The atomizer 100 also includes a second liquid reservoir 22, which is disposed in the second buffer chamber 24.

[0143] For example, the second liquid storage element 22 is, for example, absorbent cotton.

[0144] In this embodiment, by providing a second liquid storage device 22, the aerosol generation matrix in the second buffer chamber 24 can be absorbed, which further helps to improve the situation where the aerosol generation matrix leaks onto the product surface.

[0145] Of course, capillary grooves can also be provided on the cavity wall of the second buffer cavity 24 to lock the aerosol generation matrix of the second buffer cavity 24, thereby helping to improve the situation of aerosol generation matrix leaking onto the product surface.

[0146] In one specific embodiment, please refer to Figure 3 To address leakage during suction, the system first ventilates through the ventilation channel. Then, the aerosol generating matrix in the storage chamber 50 is guided from the inlet channel 60 to the second guide component 12, then to the first guide component 11, and finally to the heating element for atomization. When the aerosol generating matrix in the storage chamber 50 is at a high liquid level (second state), the ventilation resistance for gas to penetrate the aerosol generating matrix is ​​relatively large. The first guide component 11 maintains a certain liquid level through its own liquid-locking, guiding, and storage capabilities. It automatically replenishes the heating element with appropriate aerosol generating matrix based on the suction time and power, ensuring that the amount of aerosol generating matrix consumed per puff matches the suction time and / or power, thus achieving consistent and stable flavor. When the aerosol generating matrix in the storage chamber 50 is at a low liquid level (first state), the gas exchange resistance of gas penetrating the aerosol generating matrix decreases, and the supply of aerosol generating matrix increases under the same suction conditions. At this time, the excess aerosol generating matrix will be guided through the first liquid guide 11 to the first liquid storage unit 21, which has a lower density but a stronger liquid storage capacity, so that the aerosol generating matrix flowing to the heating element matches the aerosol generating matrix that needs to be consumed, thereby preventing suction leakage. When the aerosol generating matrix in the storage chamber 50 is consumed, the aerosol generating matrix stored in the first liquid storage unit 21 will also be reused by the first liquid guide 11 under the action of capillary action and gravity, so as to stabilize the liquid supply and ensure the consistency of taste during the suction process, thereby improving the problems of suction leakage and poor taste consistency caused by unstable liquid supply; at the same time, it also improves the utilization rate of aerosol generating matrix and avoids the waste of squeezed-out aerosol generating matrix. At the same time, by setting a number of interconnected ventilation slots 314 on the atomizing seat 31 for auxiliary ventilation, the problem of insufficient liquid supply caused by the first liquid guide 11 and the second liquid guide 12 being soaked in the aerosol generating matrix for a long time, causing the volume expansion and blockage of the ventilation channel, is improved. This prevents the aerosol generating matrix in the liquid storage chamber 50 from being replenished to the heating element in time, thus causing the a burnt smell during extraction.

[0147] Regarding leakage during storage, leakage mainly occurs when the aerosol generating matrix in the storage chamber 50 is at a low liquid level (first state). In this state, the cavity in the storage chamber 50 increases, and the thermal expansion of air easily squeezes the aerosol generating matrix out of the heating element, resulting in leakage. When the aerosol generating matrix in the storage chamber 50 is at a low liquid level, the first storage element 21 maintains a low-saturation state, capable of absorbing and containing the aerosol generating matrix. When the ambient temperature rises, the thermal expansion of air causes the aerosol generating matrix squeezed out of the storage chamber 50 to first flow through the second liquid guide 12 to the first liquid guide 11, and finally to the first storage element 21 where it is absorbed. This multi-stage liquid guide increases the flow resistance of the aerosol generating matrix, while the strong storage capacity of the first storage element 21 absorbs the squeezed-out aerosol generating matrix, maintaining a balanced pressure in the storage chamber 50. When the ambient temperature decreases, the air contracts due to the cold, reducing the pressure in the storage chamber 50. This causes the aerosol-generating matrix on the first storage element 21 to be drawn back into the storage chamber 50 through the liquid guide, thus maintaining the pressure balance in the storage chamber 50. The first and second liquid guides 11 and 12 remain relatively saturated. If the environment remains at a high temperature, the first storage element 21 cannot store more aerosol-generating matrix, and excess matrix will flow out from the central hole of the heating element and be absorbed by the second storage element 22, thus improving the situation where aerosol-generating matrix leaks onto the product surface. Furthermore, the aerosol generating device can still operate stably when the external air pressure changes, especially when the external air pressure is lower than atmospheric pressure, such as in high-altitude or high-altitude environments. At this time, the external air pressure is less than the negative pressure of the liquid storage chamber 50. Under the action of pressure difference, the aerosol generating matrix in the aerosol generating matrix will be pulled out. The pulled-out aerosol generating matrix will first flow through the second liquid guiding component 12 to the first liquid guiding component 11, and finally flow to the first liquid storage component 21 to be absorbed, so as to keep the pressure of the liquid storage chamber 50 in a balanced state.

[0148] In one specific embodiment, please refer to Figure 2To address leakage during suction, during the suction process, air is first exchanged through the ventilation channel 314. Then, the aerosol generating matrix in the storage chamber 50 is guided from the inlet channel 60 to the first guiding component 11 via the guiding component, and then to the heating element for atomization. When the aerosol generating matrix in the storage chamber 50 is at a high liquid level, the air exchange resistance for gas to penetrate the aerosol generating matrix is ​​relatively large. Through the liquid locking, guiding, and storage capabilities of the first guiding component 11, a certain amount of liquid is maintained. The appropriate aerosol generating matrix is ​​automatically replenished to the heating element according to the suction time and suction power, so that the aerosol generating matrix consumed for each suction is matched with the suction time and / or suction power, thereby achieving consistent and stable taste. When the aerosol generating matrix in the storage chamber 50 is at a low liquid level, the gas exchange resistance of the gas penetrating the aerosol generating matrix decreases, and the supply of aerosol generating matrix increases under the same suction conditions. At this time, part of the excess aerosol generating matrix will flow to the first buffer chamber, and the other part will be guided through the first liquid guide 11 to the first liquid storage 21, which has a lower density but a stronger liquid storage capacity. This ensures that the aerosol generating matrix flowing to the heating element is always matched with the aerosol generating matrix that needs to be consumed, thereby preventing the occurrence of suction leakage. When the aerosol generating matrix in the storage chamber 50 is depleted, the aerosol generating matrix in the first buffer chamber will flow back into the first liquid guide 11 through the capillary groove under the suction negative pressure. At the same time, the aerosol generating matrix stored in the first storage chamber 21 will also be reused by the first liquid guide 11 under capillary action and gravity, thus maintaining a stable liquid supply and ensuring a stable and consistent amount of smoke during the suction process. This improves the problems of leakage and poor taste consistency caused by unstable liquid supply. It also improves the utilization rate of the aerosol generating matrix and avoids the waste of squeezed-out aerosol generating matrix. In addition, the atomizing seat 31 is equipped with a connected ventilation groove 314 and is connected to the ventilation hole 141 on the mounting part 14 for auxiliary ventilation. This improves the situation where the first liquid guide 11 expands in volume after being soaked in the aerosol generating matrix for a long time and blocks the ventilation groove 314 on the ventilation channel, which prevents the aerosol generating matrix in the storage chamber 50 from being replenished to the heating element in time, resulting in insufficient liquid supply and causing a burnt taste during suction.

[0149] To prevent leakage, the aerosol-generating matrix in the storage chamber 50 is at a low liquid level, and the first storage component 21 remains in a low-saturation state, capable of absorbing and containing the aerosol-generating matrix. When the ambient temperature rises, the air expands due to heat, causing some of the aerosol-generating matrix squeezed out of the storage chamber 50 to be stored through the first buffer chamber, while the other part is guided through the first liquid guide 11 to the first storage component 21 for absorption, thus maintaining the pressure balance in the storage chamber 50. When the ambient temperature drops, the air contracts due to cold, reducing the pressure in the storage chamber 50. Part of the aerosol-generating matrix in the first buffer chamber is reversed and drawn back into the storage chamber 50 through the first liquid guide 11, while the other part is reversed and drawn back into the storage chamber 50 from the first storage component 21, thereby maintaining the pressure balance in the storage chamber 50, while the first liquid guide 11 remains in a relatively saturated state. If continuously exposed to high temperatures, the first buffer chamber and the first liquid storage unit 21 cannot store more aerosol generation matrix. Excess aerosol generation matrix will flow out from the central hole of the heating element and be absorbed by the second liquid storage unit 22, thereby improving the situation where aerosol generation matrix leaks onto the product surface. Furthermore, when the external air pressure changes, the aerosol generation device of this embodiment can still operate stably, especially when the external air pressure is lower than atmospheric pressure, such as in high-altitude or high-altitude environments. At this time, when the external air pressure is less than the negative pressure of the liquid storage chamber 50, the aerosol generation matrix in the liquid storage chamber 50 will be pulled out under the pressure difference. Part of the pulled-out aerosol generation matrix will flow through the first liquid guide 11 to the first buffer chamber for storage, and the other part will be guided through the first liquid guide 11 to the first liquid storage unit 21 for absorption, always maintaining the pressure in the liquid storage chamber 50 in a balanced state. This achieves stable and consistent liquid supply at different liquid levels during the suction process, solving the problems of suction leakage and inconsistent taste; and utilizes the reversible back-suction capability of the buffer unit 20 to solve the problem of leakage during storage.
