Description

Technical Field

[0001] This application belongs to the technical field of aerosol generating equipment, and more specifically, relates to an aerosol generating device. Background Technology

[0002] With the continuous improvement of living standards, aerosol generators, especially portable aerosol generators, have rapidly entered thousands of households due to their convenience and practicality, gaining widespread popularity in the market and experiencing continuous expansion in usage. Existing aerosol generators typically use a liquid guiding component to deliver the atomizing liquid to the atomization area, and then convert the liquid into an aerosol through methods such as heating or ultrasound.

[0003] However, existing aerosol generating equipment has the risk of leakage under extreme conditions such as high temperature and negative pressure. Specifically, under high temperature, the viscosity of the atomizing liquid decreases and the fluidity increases, resulting in the supply of atomizing liquid per unit time far exceeding the amount required for atomization, causing leakage or insufficient atomization. Under negative pressure, the atomizing liquid flows faster due to the siphon effect, further aggravating the risk of leakage. Utility Model Content

[0004] The purpose of this application is to provide an aerosol generating device, which aims to solve the technical problem that existing aerosol generating devices have the risk of leakage under extreme conditions such as high temperature and negative pressure.

The liquid guiding elements are used to store and transport liquid to be atomized. The buffer liquid separating element is disposed between two adjacent liquid guiding elements to form a buffer space between the two adjacent liquid guiding elements. The buffer space is used to slow down the flow rate of the liquid to be atomized in the liquid guiding assembly. The liquid atomizing assembly is at least partially located inside the liquid guiding assembly and is used to atomize the liquid to be atomized in the liquid guiding assembly into an aerosol.

[0006] Optionally, the liquid guiding assembly includes a first liquid guiding element and a second liquid guiding element arranged sequentially, with the liquid atomizing assembly located at least partially within the first liquid guiding element; wherein the density of the first liquid guiding element is higher than the density of the second liquid guiding element.

[0007] Optionally, the liquid guiding assembly includes a plurality of first liquid guiding elements, which are arranged sequentially along the extending direction of the first liquid guiding elements.

[0008] Optionally, the liquid guiding assembly includes a plurality of second liquid guiding elements, which are arranged sequentially along the extending direction of the first liquid guiding element.

[0009] Optionally, multiple second liquid guiding elements may have the same density.

[0010] Optionally, in two adjacent second liquid guiding elements, the density of the second liquid guiding element closer to the first liquid guiding element is higher than the density of the second liquid guiding element farther away from the first liquid guiding element.

[0011] Optionally, the liquid guiding assembly includes a first buffer liquid barrier, which has a first contact surface and a second contact surface disposed opposite to each other.

[0015] The beneficial effects of the aerosol generator provided in this application are as follows: Compared with the prior art, the aerosol generator provided in this application, by setting a buffer liquid separator between two adjacent liquid guides, can form a buffer space between the two adjacent liquid guides. Through the fluid resistance of the buffer space, the aerosol generator can stabilize the flow rate of the liquid to be atomized in a high-temperature environment, preventing the liquid to be atomized from flowing too fast due to the decrease in viscosity. In a negative pressure environment, the buffer space balances the negative pressure suction effect, maintaining a suitable liquid supply rate to be atomized, ensuring that the liquid to be atomized can be fully atomized by the liquid atomizing component, while effectively reducing the risk of leakage of the aerosol generator and ensuring that the aerogel has a good taste.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0033] As described in the background section, with the continuous improvement of living standards, aerosol generators, especially portable aerosol generators, have rapidly entered thousands of households due to their convenience and practicality, gaining widespread popularity in the market and experiencing continuous expansion in usage. Existing aerosol generators typically use a liquid guiding component to deliver the atomizing liquid to the atomization area, converting the liquid into an aerosol through heating or ultrasonic methods. However, existing aerosol generators pose a risk of leakage under extreme operating conditions such as high temperature and negative pressure.

[0034] Understandably, in high-temperature environments, the viscosity of the atomizing liquid decreases and its fluidity increases, resulting in the supply of atomizing liquid per unit time far exceeding the amount required for atomization, leading to leakage or insufficient atomization. In negative pressure environments, the atomizing liquid flows faster due to the siphon effect, further exacerbating the risk of leakage.

[0035] See Figures 1 to 6As shown, to solve the above problems, according to one aspect of this application, an embodiment of this application provides an aerosol generating device. The aerosol generating device includes: an atomizing unit 10, which includes a liquid guiding component 11 and a liquid atomizing component 12. The liquid guiding component 11 includes a plurality of sequentially arranged liquid guiding elements and at least one buffer liquid separating element. The liquid guiding elements are used to store and transport the liquid to be atomized. The buffer liquid separating element is disposed between two adjacent liquid guiding elements to form a buffer space between the two adjacent liquid guiding elements. The buffer space is used to slow down the flow rate of the liquid to be atomized in the liquid guiding component 11. The liquid atomizing component 12 is at least partially located within the liquid guiding component 11 and is used to atomize the liquid to be atomized in the liquid guiding component 11 into an aerosol. It should be noted that the liquid atomizing component 12 in this embodiment refers to a device that can convert the liquid to be atomized into an aerosol form through a specific method such as heating or ultrasound. The aerosol generator provided in this embodiment creates a buffer space between two adjacent liquid guiding components by setting a buffer liquid separating component. Through the fluid resistance of the buffer space, the aerosol generator can stabilize the flow rate of the liquid to be atomized in a high-temperature environment, preventing the liquid to be atomized from flowing too fast due to the decrease in viscosity. In a negative pressure environment, the buffer space balances the negative pressure suction effect, maintaining a suitable supply rate of the liquid to be atomized, ensuring that the liquid to be atomized can be fully atomized by the liquid atomizing component 12, while effectively reducing the risk of leakage of the aerosol generator and ensuring that the aerogel has a good taste.

[0036] In some embodiments, the buffer liquid separator in this embodiment is made of polycarbonate. Of course, in other embodiments, the buffer liquid separator in this embodiment can also be made of other materials capable of isolating the liquid to be atomized.

[0037] In some embodiments, the liquid guiding component in this embodiment is made of absorbent cotton, for example, absorbent cotton with a porous structure made of high-purity cellulose fiber, polyester fiber, ceramic fiber, glass fiber-based composite material, etc.

[0038] In one specific embodiment, the liquid guiding component 11 includes a first liquid guiding element 111 and a second liquid guiding element 112 arranged sequentially, with the liquid atomizing component 12 at least partially located within the first liquid guiding element 111; wherein the density of the first liquid guiding element 111 is higher than the density of the second liquid guiding element 112. By setting the density of the first liquid guiding element 111 to be higher than that of the second liquid guiding element 112, the aerosol generating device in this embodiment can provide stronger capillary force through the higher-density first liquid guiding element 111 to stably deliver the liquid to be atomized, while the lower-density second liquid guiding element 112 forms a buffer zone in the liquid guiding component 11, effectively suppressing the flow rate fluctuation of the liquid to be atomized under high temperature and negative pressure environments. While ensuring the atomization efficiency of the liquid to be atomized, the leakage risk of the aerosol generating device in this embodiment is significantly reduced, ensuring that the aerogel has a good taste.

[0039] It is understandable that in this embodiment, when the aerogel generating device encounters a high-temperature or negative-pressure environment, the flow of the liquid to be atomized will accelerate. At this time, the liquid to be atomized needs to form a new equilibrium point in the liquid guiding component 11. When the first liquid guiding component 111 and the second liquid guiding component 112 are arranged sequentially from bottom to top, the liquid to be atomized will flow upward from the bottom end of the first liquid guiding component 111. When the first liquid guiding component 111 is filled with the liquid to be atomized, the buffer liquid separating component set between the first liquid guiding component 111 and the second liquid guiding component 112 can, on the one hand, physically isolate the first liquid guiding component 111 and the second liquid guiding component 112 to prevent the liquid to be atomized from continuing to flow upward to the second liquid guiding component 112. On the other hand, the buffer liquid separating component set between the first liquid guiding component 111 and the second liquid guiding component 112 will result in a certain gap between the first liquid guiding component 111 and the second liquid guiding component 112, that is, the first liquid guiding component... A buffer space is formed between the first liquid guide 111 and the second liquid guide 112. In this embodiment, when the aerogel generating device encounters a high-temperature environment or a negative pressure environment, causing the first liquid guide 111 to fail (i.e., when the first liquid guide 111 is full but the liquid to be atomized continues to enter the first liquid guide 111), the liquid to be atomized on the first liquid guide 111 can first enter the buffer space for buffering, reducing the flow rate of the liquid to be atomized, and then enter the second liquid guide 112. This avoids the second liquid guide 112 from failing and leaking oil due to the excessive flow rate of the liquid to be atomized. At the same time, after the external high-temperature environment or negative pressure environment disappears, since the first liquid guide 111 and the second liquid guide 112 are arranged sequentially from bottom to top, the liquid to be atomized in the second liquid guide 112 can flow back to the first liquid guide 111 under the action of gravity, improving the utilization rate of the liquid to be atomized in the aerogel generating device in this embodiment.

[0040] In one specific embodiment, the liquid guiding component 11 includes a plurality of first liquid guiding elements 111, which are arranged sequentially along the extending direction of the first liquid guiding elements 111. By setting the plurality of first liquid guiding elements 111 arranged sequentially, a multi-level buffer structure can be formed within the liquid guiding component 11, enabling the aerosol generator in this embodiment to adjust the flow rate of the liquid to be atomized step by step. Specifically, in a high-temperature environment, the arrangement of the plurality of first liquid guiding elements 111 can extend the flow path of the liquid to be atomized and increase the flow resistance of the liquid to be atomized, thereby ensuring that the liquid to be atomized in the liquid guiding component 11 has a relatively stable flow rate. In a negative pressure environment, the arrangement of the plurality of first liquid guiding elements 111 can form a graded pressure reduction within the liquid guiding component 11, thereby effectively suppressing the siphon effect caused by negative pressure, and thus significantly improving the working stability and leakage prevention performance of the aerosol generator under extreme conditions.

[0041] In one specific embodiment, the liquid guiding component 11 includes a plurality of second liquid guiding elements 112, which are arranged sequentially along the extending direction of the first liquid guiding element 111. By setting the plurality of sequentially arranged second liquid guiding elements 112, a multi-level buffer structure can be formed within the liquid guiding component 11, enabling the aerosol generator in this embodiment to adjust the flow rate of the liquid to be atomized step by step. Specifically, in a high-temperature environment, the arrangement of the plurality of second liquid guiding elements 112 can extend the flow path of the liquid to be atomized and increase the flow resistance of the liquid to be atomized, thereby ensuring that the liquid to be atomized in the liquid guiding component 11 has a relatively stable flow rate. In a negative pressure environment, the arrangement of the plurality of second liquid guiding elements 112 can form a graded pressure reduction within the liquid guiding component 11, thereby effectively suppressing the siphon effect caused by negative pressure, and thus significantly improving the working stability and leakage prevention performance of the aerosol generator under extreme conditions.

[0042] In some embodiments, the plurality of second liquid guiding elements 112 in this embodiment are arranged sequentially in the vertical direction and are all located above the first liquid guiding element 111. Arranging the plurality of second liquid guiding elements 112 sequentially in the vertical direction and all located above the first liquid guiding element 111 allows the liquid to be atomized in the second liquid guiding elements 112 to flow back to the first liquid guiding element 111 under the action of gravity, effectively improving the utilization rate of the aerogel generating device for the liquid to be atomized in this embodiment.

[0043] See Figure 2 and Figure 3As shown, in some embodiments, the first liquid guiding member 111, the buffer liquid separating member, and the second liquid guiding member 112 all extend in the vertical direction. The projection of the buffer liquid separating member in the extending direction of the first liquid guiding member 111 coincides with the projections of the first liquid guiding member 111 and the second liquid guiding member 112 in their respective extending directions. By setting the projection of the buffer liquid separating member in the extending direction of the first liquid guiding member 111 to coincide with the projections of the first liquid guiding member 111 and the second liquid guiding member 112 in their respective extending directions, a buffer space can be formed between the first liquid guiding member 111 and the second liquid guiding member 112.

[0044] In some embodiments, a buffer liquid-separating element is provided between two adjacent second liquid guiding elements 112 in this embodiment. Both the second liquid guiding element 112 and the buffer liquid-separating element extend in the vertical direction, and the projection of the buffer liquid-separating element in the extension direction of the second liquid guiding element 112 coincides with the projection portions of the two adjacent second liquid guiding elements 112 in their extension direction. By setting the projection of the buffer liquid-separating element in the extension direction of the second liquid guiding element 112 to coincide with the projection portions of the two adjacent second liquid guiding elements 112 in their extension direction, a buffer space can be formed between the two adjacent second liquid guiding elements 112.

[0045] In one specific embodiment, the multiple second liquid guiding elements 112 have the same density. By setting the density of the multiple second liquid guiding elements 112 to be the same, the multiple second liquid guiding elements 112 can provide a uniformly distributed buffer resistance to the liquid to be atomized in the liquid guiding assembly 11, ensuring that the liquid to be atomized can maintain a stable laminar flow state in the multi-stage buffer structure composed of multiple second liquid guiding elements 112. That is, it enables the liquid guiding assembly 11 to ensure that the liquid to be atomized inside it can maintain a uniform deceleration flow in a high-temperature environment and provide a consistent decompression gradient in a negative pressure environment. While simplifying the structural design of the liquid guiding assembly 11, it maintains the atomization stability and leakage prevention performance of the aerosol generator.

[0046] In one specific embodiment, among two adjacent second liquid guiding elements 112, the density of the second liquid guiding element 112 closer to the first liquid guiding element 111 is higher than the density of the second liquid guiding element 112 farther from the first liquid guiding element 111. By setting the density of the second liquid guiding element 112 closer to the first liquid guiding element 111 to be higher than the density of the second liquid guiding element 112 farther from the first liquid guiding element 111, a progressive flow resistance structure can be formed in the liquid guiding assembly 11. Specifically, the high-density second liquid guiding element 112 closer to the first liquid guiding element 111 ensures stable delivery of the liquid to be atomized, while the low-density second liquid guiding element 112 farther from the first liquid guiding element 111 enhances the negative pressure absorption capacity. This allows the liquid guiding assembly 11 to achieve automatic stepwise adjustment of the flow rate of the liquid to be atomized under high temperature and negative pressure conditions, significantly improving the atomization uniformity and leak-proof reliability of the aerosol generator in this embodiment.

[0047] In one specific embodiment, the liquid guiding component 11 includes a first buffer liquid barrier 113. The first buffer liquid barrier 113 has a first contact surface and a second contact surface disposed opposite to each other. The first buffer liquid barrier 113 contacts and engages with the first liquid guiding component 111 through the first contact surface, and contacts and engages with the second liquid guiding component 112 through the second contact surface. By providing the first buffer liquid barrier 113 with the first contact surface and the second contact surface, a stable transition connection structure can be formed between the first liquid guiding component 111 and the second liquid guiding component 112 through the contact engagement of the first contact surface with the first liquid guiding component 111 and the contact engagement of the second contact surface with the second liquid guiding component 112, ensuring that the aerosol generating device in this embodiment has good operational reliability.

[0048] In one specific embodiment, the first contact surface includes at least one of a plane, an inclined plane, a conical surface, an arc-shaped surface, and a wavy surface. By configuring the first contact surface as at least one of a plane, an inclined plane, a conical surface, an arc-shaped surface, or a wavy surface, the first buffer liquid separator 113 can select the optimal contact form according to the fluid characteristics. It can achieve stable flow guidance through a planar structure, and generate controllable turbulence to adjust the flow rate of the liquid to be atomized through a non-planar structure, thereby optimizing the atomization efficiency and flow control accuracy of the aerosol generator. It is understood that the contact between the first contact surface and the first liquid guide 111 in this embodiment is at least one of point contact, line contact, surface contact, multi-point contact, multi-line contact, and multi-surface contact, and the size of the first buffer space can decrease to a certain extent as the contact area between the first contact surface and the first liquid guide 111 increases.

[0049] In one specific embodiment, the second contact surface includes at least one of a plane, an inclined plane, a conical surface, an arc-shaped surface, and a wavy surface. By configuring the second contact surface as at least one of a plane, an inclined plane, a conical surface, an arc-shaped surface, or a wavy surface, the first buffer liquid separator 113 can select the optimal contact form according to the fluid characteristics. It can achieve stable flow guidance through a planar structure, and generate controllable turbulence to adjust the flow rate of the liquid to be atomized through a non-planar structure, thereby optimizing the atomization efficiency and flow control accuracy of the aerosol generator. It is understood that the contact between the second contact surface and the second liquid guide 112 in this embodiment is at least one of point contact, line contact, surface contact, multi-point contact, multi-line contact, and multi-surface contact, and the size of the first buffer space can decrease to a certain extent as the contact area between the second contact surface and the second liquid guide 112 increases.

[0050] In one specific embodiment, the liquid guiding assembly 11 includes a second buffer liquid barrier. The second buffer liquid barrier has a third contact surface and a fourth contact surface disposed opposite to each other. The second buffer liquid barrier contacts and engages with the second liquid guiding component 112 closest to the first liquid guiding component 111 among two adjacent second liquid guiding components 112 through the third contact surface, and contacts and engages with the second liquid guiding component 112 furthest from the first liquid guiding component 111 among two adjacent second liquid guiding components 112 through the fourth contact surface. By providing the second buffer liquid barrier with the third contact surface and the fourth contact surface, a stable transition connection structure can be formed between two adjacent second liquid guiding components 112 through the contact engagement of the third contact surface with the corresponding second liquid guiding component 112 and the contact engagement of the fourth contact surface with the corresponding second liquid guiding component 112, ensuring that the aerosol generating device in this embodiment has good operational reliability.

[0051] In one specific embodiment, the third contact surface includes at least one of a plane, an inclined plane, a conical surface, an arc-shaped surface, and a wavy surface. By configuring the third contact surface as at least one of a plane, an inclined plane, a conical surface, an arc-shaped surface, or a wavy surface, the second buffer liquid separator can select the optimal contact form according to the fluid characteristics. It can achieve stable flow guidance through a planar structure, and generate controllable turbulence to adjust the flow rate of the liquid to be atomized through a non-planar structure, thereby optimizing the atomization efficiency and flow control accuracy of the aerosol generator. It is understood that the contact between the third contact surface and the second liquid guide 112 in this embodiment is at least one of point contact, line contact, surface contact, multi-point contact, multi-line contact, and multi-surface contact, and the size of the second buffer space can decrease to a certain extent as the contact area between the third contact surface and the second liquid guide 112 increases.

[0052] In one specific embodiment, the fourth contact surface includes at least one of a plane, an inclined plane, a conical surface, an arc-shaped surface, and a wavy surface. By configuring the fourth contact surface as at least one of a plane, an inclined plane, a conical surface, an arc-shaped surface, or a wavy surface, the second buffer liquid separator can select the optimal contact form according to the fluid characteristics. It can achieve stable flow guidance through a planar structure, or generate controllable turbulence to adjust the flow rate of the liquid to be atomized through a non-planar structure, thereby optimizing the atomization efficiency and flow control accuracy of the aerosol generator. It is understood that the contact between the fourth contact surface and the second liquid guide 112 in this embodiment is at least one of point contact, line contact, surface contact, multi-point contact, multi-line contact, and multi-surface contact, and the size of the second buffer space can decrease to a certain extent as the contact area between the fourth contact surface and the second liquid guide 112 increases.

[0053] See Figures 2 to 6 As shown, in some embodiments, the atomizing unit 10 in this embodiment further includes an atomizing cover 13, which contains an atomizing chamber. In this embodiment, both the liquid guiding component 11 and the liquid atomizing component 12 are installed within the atomizing chamber. It should be noted that the atomizing cover 13 in this embodiment refers to the outer shell structure surrounding the liquid guiding component 11 and the liquid atomizing component 12. The atomizing chamber formed inside it is a closed or semi-closed space for fixing and installing the liquid guiding component 11 and the liquid atomizing component 12. By providing an atomizing cover 13 with an atomizing chamber, an integrated installation space and protective structure can be provided for the liquid guiding component 11 and the liquid atomizing component 12. While ensuring the precise positioning and stable cooperation of each functional component, it effectively isolates the external environment from interference with the liquid guiding component 11 and the liquid atomizing component 12, thereby improving the overall structural strength and operational reliability of the aerosol generator in this embodiment.

[0054] See Figure 2 and Figure 3 As shown, in some embodiments, the aerosol generator in this embodiment further includes a liquid supply unit 20. In this embodiment, the liquid supply unit 20's outlet is connected to the liquid inlet of the atomizing unit 10, and is used to supply the liquid to be atomized into the atomizing unit 10. It should be noted that the liquid supply unit 20 in this embodiment refers to the functional module in the aerosol generator used for storing and supplying the liquid to be atomized. By providing a liquid supply unit 20 connected to the atomizing unit 10, a complete liquid delivery system can be formed within the aerosol generator, ensuring that the liquid to be atomized can be continuously and stably supplied to the atomizing unit 10.

It should be noted that the mouthpiece 30 in this embodiment refers to the functional terminal component in the aerosol generator that allows the user's mouth to contact and inhale the aerosol. By providing a mouthpiece 30 connected to the air outlet of the atomizing unit 10, a complete aerosol delivery channel can be constructed on the aerosol generator, ensuring that the atomized aerosol can be directed out for the user to inhale.

[0056] In some embodiments, the nozzle portion 30 in this embodiment includes a nozzle body 31 and an air outlet chamber disposed within the nozzle body 31. The air outlet chamber forms an air outlet at the end of the nozzle body 31 away from the atomizing portion 10. It should be noted that the nozzle body 31 in this embodiment is the main structure of the nozzle portion 30, constituting the outer frame and basic support of the nozzle portion 30. Its interior forms a channel for the flow of aerosol, and the material is usually selected from food-grade silicone, plastic, and other materials that meet hygiene requirements and have a certain degree of heat resistance.

[0057] It is understood that the air outlet in this embodiment refers to the cavity structure inside the mouthpiece body 31, which is the key channel for the aerosol to be transferred from atomization to the air outlet. The air outlet is located at the end of the mouthpiece body 31 away from the atomizing part 10, and is the exit for the aerosol to leave the mouthpiece part 30 and enter the user's mouth.

[0058] See Figure 2 and Figure 3 As shown, in some embodiments, the nozzle portion 30 in this embodiment further includes a first sealing element 32. In this embodiment, the air outlet chamber forms an air inlet at the end of the nozzle body 31 near the atomizing part 10, and the air inlet of the air outlet chamber forms the air inlet end of the nozzle portion 30. An aerosol channel is formed in the liquid guiding assembly 11, and the end of the aerosol channel near the nozzle portion 30 forms the air outlet end of the atomizing part 10. The air inlet end of the nozzle portion 30 and the air outlet end of the atomizing part 10 are sealed and connected by the first sealing element 32. It should be noted that the first sealing element 32 in this embodiment refers to a sealing element disposed at the connection between the air inlet end of the nozzle portion 30 and the air outlet end of the atomizing part 10. It forms an airtight fit with the mating parts through elastic deformation, so that the aerosol channel forms a closed transmission path.

[0059] See figure to Figure 3As shown, in some embodiments, the aerosol generator in this embodiment further includes a device body 40. The atomizing section 10, the liquid supply section 20, and the nozzle section 30 in this embodiment are all installed on the device body 40. It should be noted that the device body 40 in this embodiment refers to the basic structural frame of the aerosol generator used to support and fix the atomizing section 10, the liquid supply section 20, and the nozzle section 30. It has corresponding mounting positions and connection channels inside to realize the mechanical integration and fluid communication of each functional module.

[0060] See Figure 2 As shown, in some embodiments, the liquid supply unit 20 in this embodiment includes a first liquid storage chamber 21 and a control valve 22. In this embodiment, the first liquid storage chamber 21 is disposed within the device body 40 and is used to contain the liquid to be atomized. The control valve 22 is installed on the device body 40, and the inlet end of the control valve 22 is connected to the first liquid storage chamber 21, while the outlet end of the control valve 22 is connected to the first liquid guide 111. It should be noted that in this embodiment, the first liquid storage chamber 21 refers to the sealed cavity within the device body 40 used to store the liquid to be atomized; the control valve 22 refers to the flow control element installed between the liquid storage chamber and the first liquid guide 111, which controls the delivery rate of the liquid to be atomized by adjusting the valve opening. By setting up a liquid supply section 20 including a first liquid storage chamber 21 and a liquid control valve 22, precise delivery of the liquid to be atomized can be achieved. The first liquid storage chamber 21 can provide a stable liquid source for atomization, while the liquid control valve 22 can precisely adjust the flow rate of the liquid to be atomized, ensuring that the first liquid guide 111 can obtain a continuous and balanced supply of the liquid to be atomized.

[0061] See Figure 2 As shown, in some embodiments, the liquid supply unit 20 in this embodiment includes a second liquid storage chamber 23, which is disposed within the main body 40 of the device. The outlet end of the control valve 22 is connected to the second liquid storage chamber 23, and the atomizing cover 13 is provided with a liquid supply port 131 connecting the second liquid storage chamber 23 and the first liquid guide 111. It should be noted that, in this embodiment, the second liquid storage chamber 23 refers to a secondary liquid buffer chamber disposed within the main body 40 of the device, which forms a cascaded liquid supply system with the first liquid storage chamber 21 through the control valve 22; the liquid supply port 131 in this embodiment refers to a fluid channel provided on the atomizing cover 13 that connects the second liquid storage chamber 23 and the first liquid guide 111. By setting up a linkage structure between the second liquid storage chamber 23 and the control valve 22, a two-stage liquid buffer system can be formed in the aerosol generator. This allows the aerosol generator to precisely adjust the flow rate of the liquid to be atomized through the control valve 22, balance the pressure fluctuations of the liquid to be atomized using the second liquid storage chamber 23, and stably deliver the liquid to be atomized to the first liquid guide 111 through the liquid supply port 131. This ensures that the aerosol generator in this embodiment can maintain high stability of the atomization flow rate even under complex operating conditions.

[0062] See Figure 2 As shown, in some embodiments, the end of the aerosol channel furthest from the nozzle 30 forms the air inlet of the atomizing section 10. The atomizing section 10 in this embodiment also includes a second seal 14, which is installed on the liquid guiding assembly 11 to isolate and seal the air inlet of the atomizing section 10 and the second liquid storage chamber 23. It should be noted that the second seal 14 in this embodiment refers to a sealing element disposed between the air inlet of the atomizing section 10 and the second liquid storage chamber 23, achieving independent sealing of the airflow channel and the liquid storage chamber through physical isolation. By isolating the air inlet of the atomizing section 10 and the second liquid storage chamber 23 with the second seal 14, the integrity of the airflow in the aerosol channel can be ensured.

[0063] In some embodiments, the main body 40 of the device in this embodiment is provided with an air inlet channel. The air inlet of the air inlet channel in this embodiment is connected to the external environment, and the air outlet of the air inlet channel is connected to the air inlet end of the atomizing part 10. The aerogel generating device in this embodiment also includes an air regulating plate. The air regulating plate in this embodiment is movably installed on the main body 40 of the device and can at least partially block the air inlet of the air inlet channel to adjust the communication area between the air inlet of the air inlet channel and the external environment.

[0064] See Figure 2 and Figure 3 As shown, in some embodiments, the aerosol generator in this embodiment further includes a power supply unit 50 and a control unit. In this embodiment, the control unit is connected to the power supply unit 50, and the liquid atomizing component 12 is electrically connected to the control unit. The power supply unit 50 can provide a stable power source for the liquid atomizing component 12. The control unit is electrically connected to the power supply unit 50 and the liquid atomizing component 12, enabling the control unit to precisely regulate the working state of the liquid atomizing component 12. For example, the control component can adjust the current or voltage output to the liquid atomizing component 12 according to a preset program or parameters detected in real time, thereby achieving operational control of the liquid atomizing component 12.

[0065] See Figure 2As shown, in some embodiments, the aerosol generator in this embodiment further includes a button unit, which includes a button body and a button control component electrically connected to the control unit. The button body provides the user with an intuitive, physical operating interface. The user can transmit commands to the control unit through the button control component by simple actions such as pressing, thereby controlling the functions of the device. Compared with touch or sensing methods without physical buttons, the operation feedback of physical buttons is more explicit, and the user can clearly perceive whether the operation is effective. Especially in low light or blind operation scenarios, the operation accuracy is higher, greatly improving the ease of use of the device. In terms of functional control precision, the button control component is electrically connected to the control unit, forming a stable command transmission path. When the user operates the button body, the button control component can convert the mechanical action into an electrical signal and accurately transmit it to the control unit. After processing the signal according to the preset program, the control unit regulates the working state of related components such as the liquid control valve 22 and the liquid atomizing component 12.

[0066] In summary, the aerosol generator provided in this embodiment has at least the following beneficial technical effects: The aerosol generator provided in this embodiment, by setting a buffer liquid separator between two adjacent liquid guides, can form a buffer space between the two adjacent liquid guides. Through the fluid resistance of the buffer space, the aerosol generator can stabilize the flow rate of the liquid to be atomized in a high-temperature environment, preventing the liquid to be atomized from flowing too fast due to the decrease in viscosity. In a negative pressure environment, the buffer space balances the negative pressure suction effect, maintaining a suitable supply rate of the liquid to be atomized, ensuring that the liquid to be atomized can be fully atomized by the liquid atomizing component 12, while effectively reducing the risk of leakage of the aerosol generator and ensuring that the aerogel has a good taste.

[0067] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
