Description

Technical Field

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

[0002] Currently, in the field of atomization equipment, due to the relatively small size of the devices, the amount of atomizing liquid that can be stored is limited. To extend the service life, some atomizers are used with external liquid storage bottles, such as detachable replenishment packs, to add atomizing liquid from the replenishment pack into the atomization chamber when needed for atomization to generate aerosols. However, in existing atomization devices with replenishment functions, the operating mechanism used for replenishment is prone to leakage during use (e.g., when replenishing too quickly), affecting the user experience.

[0010] In some embodiments, as the active unit moves relative to the second housing, the sum of the volumes of the first and second volume spaces remains constant.

[0011] In some embodiments, the first volume space is used to store the atomizing matrix; the movable unit is capable of moving within the second housing in a direction close to the first liquid inlet, so that the atomizing matrix in the first volume space is supplied to the interior of the first housing through the first liquid inlet.

Detailed Implementation

[0018] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] It should also be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. When an component is referred to as being "on" or "below" another component, the component can be located "directly" or "indirectly" on the other component, or there may be one or more intermediary components. The terms "first," "second," "third," etc., are only for the convenience of describing this technical solution and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0020] Existing nebulizers with liquid replenishment functions mainly consist of an atomizer and an additional liquid replenishment mechanism, which replenishes the liquid in the atomizer. However, due to the difficulty for operators to control the replenishment speed and volume, excessively rapid replenishment can easily lead to leakage, affecting the user experience. The inventors discovered that the reason for leakage caused by excessively rapid replenishment is as follows: Typically, the atomizer has a reservoir for storing the atomized liquid. The atomized liquid in the reservoir seeps into the atomizing core and is atomized to generate an aerosol. During normal use of the atomizer, the atomized liquid in the reservoir is gradually consumed. The volume of air above the liquid surface in the reservoir increases, but the mass of the gas remains unchanged. Therefore, the air above the liquid surface in the reservoir maintains a certain negative pressure, which can lock in the atomized liquid and prevent it from leaking out of the reservoir. However, when current liquid replenishment mechanisms replenish the atomizer, the rapid increase in the amount of liquid in the atomizer's reservoir causes a rapid increase in the volume of the liquid space within the reservoir, which in turn causes a rapid decrease in the volume of the gas space within the reservoir. This leads to an increase in the gas pressure within the reservoir, disrupting the original gas-liquid pressure balance and reducing the ability to retain the atomized liquid. Consequently, the risk of atomized liquid leakage increases.

[0021] Please see Figure 1 and Figure 2 This utility model discloses an atomizer assembly, which includes an atomizer 1 and a liquid supply unit 2. In some embodiments, the atomizer 1 and the liquid supply unit 2 are two independent modules, which are detachably connected together. The atomizer 1 is used to heat and atomize an atomizing substrate to generate an aerosol. The atomizing substrate may specifically be e-liquid, medicinal liquid, or other liquids that can be atomized and inhaled. The liquid supply unit 2 is used to replenish the atomizing substrate to the atomizer 1.

[0022] Please see Figures 3 to 5 The atomizer 1 includes a first housing 13 and an atomizing core 14 (see reference). Figure 7The atomizing core 14 is disposed within the first housing 13 and is used to atomize the atomizing matrix into an aerosol. Specifically, in some embodiments, the atomizing core 14 includes an electric heating element that heats up when energized, thereby heating and atomizing the atomizing matrix into an aerosol. Alternatively, in other embodiments, the atomizing core 14 includes an electromagnetic sensor element that heats up through electromagnetic induction, thereby heating and atomizing the atomizing matrix into an aerosol. Alternatively, in other embodiments, the atomizing core 14 includes an ultrasonic generating element that uses the high-frequency vibration of ultrasound to convert the liquid atomizing matrix into tiny droplets, thereby generating an aerosol and achieving an atomization effect. Alternatively, in other embodiments, the atomizing core 14 includes a light wave generating element that generates light energy and high-temperature heat energy to heat and atomize the atomizing matrix into an aerosol. Alternatively, in some embodiments, the atomizing core 14 includes an infrared light generating element that uses infrared radiation energy to heat and atomize the atomizing matrix to generate an aerosol. Alternatively, in some embodiments, the atomizing core 14 includes a microwave generating element that heats and atomizes the atomizing matrix to generate an aerosol when the atomizing matrix is ​​exposed to a microwave field generated by the microwave generating element.

[0023] The first liquid inlet 11 and the first air inlet 12 are formed on the first housing 13. The atomizing core 14 is disposed inside the first housing 13. Specifically, in some embodiments, the atomizer 1 further includes a liquid storage chamber 10, which is formed inside the first housing 13. The liquid storage chamber 10 is used to store the atomizing matrix. The first liquid inlet 11 and the first air inlet 12 are respectively connected to the liquid storage chamber 10. The atomizing core 14 is in liquid-conducting communication with the liquid storage chamber 10. The atomizing core 14 can absorb the atomizing matrix from the liquid storage chamber 10 and atomize the atomizing matrix to generate an aerosol for the user to inhale. In some embodiments, the liquid storage chamber 10 can also be omitted, only requiring that the liquid supply unit 2 and the atomizing core 14 form a fluid connection to ensure that the liquid supply unit 2 can supply liquid to the atomizing core 14.

[0024] The atomizing core 14, as the core component of an electronic atomizing device, generally includes a heating element and a liquid guiding element. The heating element heats the atomizing matrix flowing into the liquid guiding element to form an aerosol. The heating element can be formed from any material with suitable electrical properties. In some specific embodiments, suitable materials include, but are not limited to: semiconductors (such as doped ceramics), “conductive” ceramics (such as molybdenum disilicide), carbon, graphite, metals, metal alloys, and / or composite materials made of ceramic and metallic materials. Such composite materials may include doped or undoped ceramics. Examples of suitable doped ceramics include doped silicon carbide. Examples of suitable metals include titanium, zirconium, tantalum, and platinum group metals. Examples of suitable metal alloys include stainless steel; constantan; nickel-containing alloys, cobalt-containing alloys, chromium-containing alloys, aluminum-containing alloys, titanium-containing alloys, zirconium-containing alloys, hafnium-containing alloys, niobium-containing alloys, molybdenum-containing alloys, tantalum-containing alloys, tungsten-containing alloys, tin-containing alloys, gallium-containing alloys, manganese-containing alloys, and iron-containing alloys; as well as nickel-, iron-, and cobalt-based superalloys, stainless steel, iron-aluminum-based alloys, and iron-manganese-aluminum-based alloys. The liquid guiding element refers to the structure that transmits the atomizing matrix to the heating element. It can be achieved through capillary action or other forces, including but not limited to ceramics, glass, quartz, or fibers. Of course, in some specific embodiments, the atomizing core 14 is not limited to an electric heating assembly, but can also be an ultrasonic atomizing assembly, an electromagnetic sensor, an infrared heating assembly, a light wave element, an infrared element, or any combination thereof. However, it should be understood that these variations do not depart from the concept of this utility model.

[0025] Please see Figures 3 to 6 The liquid supply unit 2 includes a second housing 23, a movable unit 221, a first volume space 20, and a second volume space 21. The first volume space 20 is used to store the atomizing matrix. The movable unit 221, the first volume space 20, and the second volume space 21 are disposed within the second housing 23, and the first volume space 20 and the second volume space 21 are separated on both sides by the movable unit 221. The first volume space 20 is in fluid communication with the first liquid guide port 11. The first air guide port 12 connects the interior of the first housing 13 and the second volume space 21. Specifically, in some embodiments, the first air guide port 12 connects the liquid storage chamber 10 and the second volume space 21.

[0026] The movable unit 221 is movable relative to the second housing 23 within the second housing 23, allowing the first volume space 20 to supply the atomizing matrix to the interior of the first housing 13 through the first liquid guide port 11, and allowing airflow exchange between the interior of the first housing 13 and the second volume space 21. Specifically, in some embodiments, the first volume space 20 supplies the atomizing matrix to the liquid storage chamber 10 through the first liquid guide port 11, and allows airflow exchange between the liquid storage chamber 10 and the second volume space 21. Specifically, the first volume space 20 and the second volume space 21 are two independent and isolated (i.e., not connected) cavities. From the perspective of the atomizer 1, during the movement of the movable unit 221 within the second housing 23, the atomizing matrix in the first volume space 20 flows to the liquid storage chamber 10 through the first liquid guide port 11, increasing the liquid volume and decreasing the air volume inside the first housing 13; simultaneously, the air inside the first housing 13 exchanges airflow with the second volume space 21, allowing the reduced air in the first housing 13 to enter the second volume space 21. From the perspective of the liquid supply unit 2, as the moving unit 221 moves within the second housing 23, the volume of the first volume space 20 decreases, causing the liquid within it to be squeezed and flow into the liquid storage chamber 10 inside the first housing 13; the volume of the second volume space 21 increases, creating a negative pressure that draws air from the liquid storage chamber 10 inside the first housing 13 into the second volume space 21. In this way, during the process of the liquid supply unit replenishing the atomizer, the amount of liquid inside the first housing of the atomizer increases while the amount of gas decreases, thus preventing an increase in internal air pressure during replenishment and reducing the risk of leakage due to increased air pressure.

[0027] Furthermore, although the interior of the first housing 13 (e.g., the interior of the liquid storage chamber 10) can exchange airflow with the second volume space 21, the second volume space 21 is also a sealed cavity within the second housing 23, meaning it is isolated from the external atmospheric environment. Therefore, the interior of the first housing 13 (e.g., the interior of the liquid storage chamber 10) is also isolated from the external atmospheric environment, maintaining a sealed state. In other words, airflow exchanges between the relatively sealed interior of the first housing 13 and the second volume space 21, rather than directly connecting to the external atmosphere. Consequently, the gas pressure change within the first housing 13 (e.g., the interior of the liquid storage chamber 10) is stable, minimizing the risk of leakage. As the liquid atomizing matrix within the liquid storage chamber 10 is gradually consumed, the liquid volume decreases while the air volume increases, resulting in a decrease in air pressure. The air pressure inside the liquid storage chamber 10 tends to be lower than atmospheric pressure, preventing liquid leakage from the atomizing core 14 to the outside of the liquid storage chamber 10, thus achieving a leak-proof effect. Regardless of whether the atomizer 1 is replenished with liquid, the airflow exchange between the inside of the first housing 13 and the second volume space 21 will not affect the sealed state inside the atomizer 1, and the risk of leakage is small.

[0028] Furthermore, in some embodiments, during the movement of the active unit 221, the sum of the volumes of the first volume space 20 and the second volume space 21 remains unchanged. As a result, during the process of the liquid supply unit 2 replenishing the liquid to the atomizer 1, the increase in liquid and the decrease in gas inside the atomizer 1 are approximately equal, thereby making the internal gas pressure of the atomizer 1 relatively stable during the replenishment process, thus reducing the risk of leakage of the atomizer 1.

[0029] The process of the atomizing matrix in the first volume space 20 flowing to the storage chamber 10 through the first liquid inlet 11 is the process of filling the storage chamber 10 of the atomizer 1 with liquid; the process of the air in the storage chamber 10 flowing to the second volume space 21 through the first air inlet 12 is the process of evacuating the storage chamber 10 of the atomizer 1 with air. When the movable unit 221 moves within the second housing 23, the processes of filling the storage chamber 10 of the atomizer 1 with liquid and evacuating the storage chamber 10 of the atomizer 1 are performed simultaneously. Alternatively, there may be a certain time difference between the processes of filling the storage chamber 10 of the atomizer 1 with liquid and evacuating the storage chamber 10 of the atomizer 1. In summary, during the movement of the movable unit 221, the sum of the volumes of the first volume space 20 and the second volume space 21 remains approximately constant.

[0030] In some other embodiments, the second volume space 21 may not be located within the second housing 23, but rather outside of it, independent of the second housing 23. For example, in this other embodiment, the active unit 221 may be omitted, and the atomizer assembly further includes a pressure detection component and an air extraction unit, with the air extraction unit independently located on one side of the liquid supply unit 2. The air extraction unit includes the second volume space 21, which is connected to the liquid storage chamber 10 inside the first housing 13. The pressure detection component can detect the pressure inside the first volume space 20 and the pressure inside the second volume space 21. The pressure change inside the first volume space 20 reflects the liquid consumption, and the pressure change inside the second volume space 21 reflects the increase in air volume. During each liquid replenishment process, by controlling the liquid consumption in the first volume space 20 to be equal to the increase in air volume in the second volume space 21, the internal air pressure of the atomizer 1 is kept relatively stable during liquid replenishment, thereby reducing the risk of leakage.

[0031] Please see Figure 7 , Figure 7A diagram illustrating the principle of negative pressure balance replenishment is shown, where solid arrows represent the flow direction of the liquid atomizing matrix and dashed arrows represent the flow direction of air. When the atomizing matrix in the storage chamber 10 of the atomizer 1 is consumed to a predetermined amount, replenishment is required from the first volume space 20 of the supply unit 2. At this time, the movable unit 221 moves within the second housing 23, causing the atomizing matrix in the first volume space 20 to enter the storage chamber 10, with a volume of V1. Simultaneously, a negative pressure is generated in the second volume space 21, drawing air out of the storage chamber 10, with a volume of V2 escaping from the storage chamber 10 into the second volume space 21. During the replenishment and air extraction processes described above, V1 = V2. Therefore, the volume of liquid entering the storage chamber 10 and the volume of air drawn out of the storage chamber 10 remain consistent, thus not affecting the original negative pressure of the air in the storage chamber 10.

[0032] Further, please refer to Figures 3 to 8 In some embodiments, the movable unit 221 includes a first seal 2211. The first seal 2211 is movable within the second housing 23 to supply the atomizing matrix to the interior of the first housing 13 through the first liquid inlet 11. The first volume space 20 and the second volume space 21 are separated on both sides by the first seal 2211. Specifically, in some embodiments, the atomizer 1 is longitudinally elongated, and the liquid supply unit 2 used in conjunction with the atomizer 1 is also longitudinally elongated. The atomizer assembly is typically in an upright or slightly tilted vertical position during use. Figure 8 The diagram illustrates the U and D directions, where U represents the upward direction when the atomizer assembly is upright, and D represents the downward direction. The first volume space 20 and the second volume space 21 are located on the upper and lower sides of the first seal 2211, respectively. When the movable unit 221 or the first seal 2211 moves upward a certain distance, the volume of the first volume space 20 decreases, and the atomizing matrix is ​​pushed into the liquid storage chamber 10 through the first liquid guide port 11. At the same time, the volume of the second volume space 21 increases, the air pressure inside decreases, and a negative pressure is generated, causing air in the liquid storage chamber 10 to be drawn into the second volume space 21.

[0033] Further, please refer to Figures 3 to 8In some embodiments, the liquid supply unit 2 further includes a second housing 23 and a second seal 24. The first seal 2211 is movable relative to the second seal 24 within the second housing 23, allowing the first volume space 20 to supply the atomizing matrix to the interior of the first housing 13 through the first liquid inlet 11. Initially, before the first seal 2211 begins to move within the second housing 23, the first seal 2211 and the second seal 24 may be in contact with each other; alternatively, a gap may exist between them. After the first seal 2211 moves within the second housing 23 in a direction away from the second seal 24, i.e., after the liquid injection mode is activated, the first seal 2211 and the second seal 24 are spaced apart vertically. The first seal 2211 and the second seal 24 respectively seal against the inner wall surface of the second housing 23. The first seal 2211 and the second housing 23 together define the first volume space 20. The first seal 2211, the second seal 24, and the second housing 23 together define the second volume space 21. Specifically, there is a gap between the top walls of the first seal 2211 and the second housing 23. The gap between the top walls of the first seal 2211 and the second housing 23, and the circumferential inner wall surface of the second housing 23 together enclose the first volume space 20. The gap between the first seal 2211 and the second seal 24, and the circumferential inner wall surface of the second housing 23 together enclose the second volume space 21. During the movement of the first seal 2211 within the second housing 23, the inner wall surfaces of the first seal 2211 and the second housing 23 always maintain a sealed connection.

[0034] Since the first volume space 20 and the second volume space 21 are located on the upper and lower sides of the first seal 2211 respectively, when the first seal 2211 moves upward, the first seal 2211 gradually moves away from the second seal 24, thereby increasing the gap between the first seal 2211 and the second seal 24, and thus the volume of the second volume space 21 gradually increases. Similarly, when the first seal 2211 moves upward, the first seal 2211 gradually moves closer to the top wall of the second housing 23, thereby decreasing the gap between the first seal 2211 and the top wall of the second housing 23, and thus the volume of the first volume space 20 gradually decreases.

[0035] Based on the above structure, since the first volume space 20 and the second volume space 21 are located on opposite sides of the first seal 2211, when the first seal 2211 moves away from the second seal 24, the volume change trend of the first volume space 20 and the volume change trend of the second volume space 21 are opposite. Therefore, it is possible to simultaneously replenish the liquid and pump out the air in the liquid storage chamber 10. As the first seal 2211 moves away from the second seal 24, the gas squeezed out of the liquid storage chamber 10 enters the second volume space 21, increasing the volume of the second volume space 21. Therefore, the gas inside the second volume space 21 also provides a force to push the first seal 2211 away from the second seal 24. The movement of the first seal 2211 away from the second seal 24 again causes the volume of the first volume space 20 to decrease, increasing the amount of liquid in the liquid storage chamber 10. Some gas is drawn into the second volume space 21, thus forming a positive cycle. This replenishes the liquid in the atomizer 1 without causing an increase in the gas pressure inside the atomizer 1, thereby reducing the risk of leakage.

[0036] like Figure 4 , Figure 9 and Figure 15 As shown, in some embodiments, the atomizer assembly further includes an airflow channel 231, the two ends of which are respectively connected to the first air inlet 12 and the second volume space 21. Specifically, as... Figure 5 As shown, the liquid supply unit 2 also includes a second air inlet 232, which is formed on the second housing 23. One end of the airflow channel 231 is connected to the second air inlet 232, and the other end of the airflow channel 231 is connected to the second volume space 21. The second air inlet 232 is connected to the first air inlet 12. Air in the liquid storage chamber 10 passes sequentially through the first air inlet 12, the second air inlet 232, and the airflow channel 231 before entering the second volume space 21.

[0037] like Figure 4 , Figure 9 and Figure 15 As shown, in some embodiments, the airflow channel 231 is located within the second housing 23. Alternatively, the airflow channel 231 is at least partially formed by the second housing 23. Still others, the airflow channel 231 is located within the second housing 23 and is at least partially formed by the second housing 23. Specifically, as... Figure 15 As shown, in some embodiments, the liquid supply unit 2 further includes an air guide column 25, which is formed on the inner wall surface of the second housing 23. A first seal 2211 and the outer peripheral surface of the air guide column 25 are sealed together. A second seal 24 is located below the air guide column 25. The hollow interior of the air guide column 25 forms an airflow channel 231.

[0038] Alternatively, in some other embodiments, the airflow channel 231 may not be located inside the second housing 23, but rather on the outside of the second housing 23. For example, an independent airflow channel 231 may be provided on the outside of the atomizer 1 and the liquid supply unit 2, with one end of the airflow channel 231 connected to the first air inlet 12 and the other end connected to the second volume space 21.

[0039] In some embodiments, the moving direction of the active unit 221 is parallel to the extending direction of the airflow channel 231. Alternatively, see [link to relevant documentation]. Figure 9 The moving direction of the movable unit 221 is parallel to the central axis Y of the second housing 23. The end of the airflow channel 231 away from the first air inlet 12 is located between the surface of the movable unit 221 facing the first volume space 20 and the edge of the second volume space 21 in a direction away from the first volume space 20. Specifically, the end of the airflow channel 231 away from the first air inlet 12 is also the outlet end of the airflow channel 231. The surface of the movable unit 221 facing the first volume space 20 is also the surface of the first seal 2211 facing the first volume space 20; in other words, the surface of the movable unit 221 facing the first volume space 20 is also the edge of the first volume space 20 in a direction close to the second volume space 21. The edge of the second volume space 21 in a direction away from the first volume space 20 can be the surface of the second seal 24 facing the first seal 2211; or, in the absence of the second seal 24, the edge of the second volume space 21 in a direction away from the first volume space 20 can also be the inner wall surface of the second housing 23. For example... Figure 4 As shown, in some embodiments, the end of the airflow channel 231 away from the first air inlet 12 may be located between the first seal 2211 and the second seal 24. Alternatively, in other embodiments, the end of the airflow channel 231 away from the first air inlet 12 may be disposed on the first seal 2211. For example, a portion of the airflow channel 231 penetrates the first seal 2211 and extends inside the first seal 2211. The outlet end of the airflow channel 231 may be located on the surface of the first seal 2211 facing the second volume space 21; or, as... Figure 16 As shown, the outlet end of the airflow channel 231 can be located on the outer peripheral surface of the first seal 2211. Specifically, as... Figure 16 In the illustrated embodiment, the first seal 2211 includes a first part and a second part with different radial dimensions. The first part with a larger radial dimension seals against the inner wall of the second housing 23, while the outer peripheral surface of the second part with a smaller radial dimension is spaced apart from the inner wall of the second housing 23. The outlet of the airflow channel 231 is located on the outer peripheral surface of the second part with a smaller radial dimension, and the outlet of the airflow channel 231 is connected to the second volume space 21 through the aforementioned gap.

[0040] Please see Figure 17 In the diagram, direction L represents the left, direction R represents the right, and directions L and R together represent the horizontal direction. For example... Figure 17 As shown, in some other embodiments, with Figure 7 The difference in the illustrated embodiment is that the first volume space 20 and the second volume space 21 are located on the left and right sides of the first sealing member 2211, respectively. When the first sealing member 2211 of the movable unit 221 moves to the left, the volume of the first volume space 20 gradually decreases, driving the atomizing matrix from the first volume space 20 into the liquid storage chamber 10; simultaneously, the volume of the second volume space 21 gradually increases. To balance the air pressure, air in the liquid storage chamber 10 escapes into the second volume space 21, thereby avoiding the risk of leakage due to increased air pressure in the liquid storage chamber 10. Please refer to... Figure 6 , Figure 8 and Figure 9 In some embodiments, the movable unit 221 further includes a movable member 2212, and the liquid supply unit 2 further includes a drive mechanism 222. The movable member 2212 passes through the second seal 24 and is connected to the first seal 2211. The drive mechanism 222 is used to drive the movable member 2212 to move relative to the second seal 24, thereby causing the movable member 2212 to drive the first seal 2211 to move relative to the second seal 2 within the second housing 23. That is, the movable member 2212 serves as a power transmission medium between the drive mechanism 222 and the first seal 2211, and is used to drive the first seal 2211 and the drive mechanism 222 together after passing through the second seal 24. The movable member 2212 may be an integrally formed structure with the first seal 2211; or, the movable member 2212 may be an independent structure separately formed from the first seal 2211. The drive mechanism 222 is used to provide power to push the movable member 2212 upward, thereby causing the first seal 2211 to move upward.

[0041] Specifically, the second seal 24 has a through hole that passes through the end face (upper face) of the second seal 24 facing the first seal 2211 and the end face (lower face) of the second seal 24 away from the first seal 2211. A movable member 2212 passes through this through hole. Since the movable member 2212 needs to pass through the second seal 24 to mechanically connect the first seal 2211 and the drive mechanism 222, a sealing fit is required between the movable member 2212 and the through hole of the second seal 24 to prevent liquid leakage; specifically, a dynamic sealing fit. For example, the movable member 2212 and the through hole can be an interference fit; or, a sealing ring can be provided between the movable member 2212 and the through hole.

[0042] Please see Figure 6 , Figure 8 and Figure 9In some embodiments, the movable component 2212 includes a rod portion 2212a, a first support portion 2212b, and a second support portion 2212c. The rod portion 2212a, the first support portion 2212b, and the second support portion 2212c can be integrally formed or separately formed. The first support portion 2212b and the second support portion 2212c are respectively connected to opposite ends of the rod portion 2212a. The rod portion 2212a passes through the second seal 24. The first support portion 2212b and the second support portion 2212c are respectively located on opposite sides of the second seal 24. The first support portion 2212b is connected to the first seal 2211, and the drive mechanism 222 and the second support portion 2212c are in a transmission engagement. Specifically, refer to... Figure 8 In the orientation of the rod 2212a, the first support portion 2212b and the second support portion 2212c are respectively connected to the upper and lower ends of the rod portion 2212a. The rod portion 2212a passes through a hole in the second seal 24. The first support portion 2212b and the first seal 2211 can be fitted together, for example, the first seal 2211 is nested around the outer periphery of the first support portion 2212b. The second support portion 2212c and the drive mechanism 222 can be in direct, mechanical contact, so that the drive mechanism 222 directly contacts and pushes the second support portion 2212c to move upward, thereby causing the entire movable unit 221 to move upward together. Alternatively, the second support portion 2212c and the drive mechanism 222 can also not be in direct contact, but can be driven and engaged indirectly. Indirect methods include gas propulsion, magnetic repulsion, etc. For example, a gas-driven method will be described below.

[0043] Please see Figure 6 , Figure 8 and Figure 9In some embodiments, the drive mechanism 222 includes an inflation unit. The inflation unit is disposed on the side of the second support portion 2212c opposite to the first support portion 2212b. The second support portion 2212c and the inner wall surface of the second housing 23 are sealed together. A gap space 30 is formed between the second support portion 2212c and the second seal 24. The second housing 23 is provided with an exhaust port 230, which connects the gap space 30 to the outside atmosphere. The inflation unit is used to provide airflow to push the second support portion 2212c, thereby driving the first seal 2211 to move within the second housing 23 in a direction away from the second seal 2. Specifically, after the inner wall surface of the second support portion 2212c and the second housing 23 are sealed together, there is also a sealed gap between the inflation unit and the second support portion 2212c. The inflation unit fills the gap with gas, thereby using the gas pressure to push the second support portion 2212c upward. As the second support 2212c moves upward, the second support 2212c, the rod 2212a, the first support 2212b, and the first seal 2211 move as a whole relative to the second seal 24. Furthermore, as the movable unit 221 moves away from the second seal 2, the second support 2212c gradually approaches the second seal 24, causing the volume of the space 30 to gradually decrease. Since the space 30 is connected to the outside atmosphere through the exhaust port 230, when the volume of the space 30 decreases, excess air within it is discharged into the atmosphere through the exhaust port 230, thus preventing the generation of positive pressure within the space 30 that could interfere with the movement of the movable unit 221.

[0044] Please see Figures 10 to 13 In some embodiments, the inflation unit includes a piston element 42, a second air chamber 40, and an air outlet channel 41. The piston element 42 is capable of reciprocating along the second air chamber 40 to generate airflow, and the air outlet channel 41 is used to discharge the airflow. Specifically, the gap between the inflation unit and the second support portion 2212c is connected to the air outlet channel 41. When the piston element 42 reciprocates along the second air chamber 40 to generate airflow, the airflow flows through the air outlet channel 41 to the gap between the inflation unit and the second support portion 2212c, thereby generating positive pressure to push the second support portion 2212c upward.

[0045] Further, please refer to Figures 10 to 13In some embodiments, the inflation unit further includes at least one of the following: a base 43, a button 44, a third seal 451, a fourth seal 452, a one-way valve 46, an air guide 47, an air blocking part 48, a first elastic member 491, and a second elastic member 492. The second air chamber 40 is formed inside the base 43. An air outlet channel 41 is at least partially formed inside the base 43. The button 44 and the piston element 42 are connected at the end away from the second air chamber 40, and are exposed for user touch and pressing. The third seal 451 is disposed between the piston element 42 and the cavity wall surface of the second air chamber 40 to seal the gap between the piston element 42 and the cavity wall surface of the second air chamber 40, ensuring the airtightness of the second air chamber 40. The fourth seal 452 is disposed between the inner wall surface of the base 43 and the inner wall surface of the second housing 23 to seal the gap between the inner wall surfaces of the base 43 and the second housing 23, ensuring the airtightness of the gap between the inflation unit and the second support part 2212c. A first air passage 420 is formed inside the piston element 42, and a one-way valve 46 is disposed in the first air passage 420 of the piston element 42. The one-way valve 46 allows air from outside the inflation unit to enter the second air chamber 40 through the first air passage 420, but does not allow air in the second air chamber 40 to escape to the outside of the inflation unit through the first air passage 420. A first elastic member 491 is disposed between the end of the piston element 42 away from the button 44 and the cavity wall of the second air chamber 40, and is used to provide elastic force to automatically reset the piston element 42. A groove 431 is recessed on the side of the base 43 facing the second support portion 2212c. An air guide portion 47 is disposed in the groove 431. A second air passage 470 is formed inside the air guide portion 47. A third air passage 430 is also formed inside the base 43. The third air passage 430 connects the second air passage 470 and the second air chamber 40. The second air passage 470 and the third air passage 430 together define the air outlet passage 41. The second elastic element 492 is disposed within the groove 431 and abuts against the air guide portion 47. The air blocking portion 48 is disposed within the groove 431. Specifically, the air blocking portion 48 may be a protrusion extending upward from the bottom surface of the groove 431. The first elastic element 491 and the second elastic element 492 may be springs.

[0046] like Figure 14 As shown, in the initial uninflated state, the air-blocking part 48 extends into the second air passage 470, and the air outlet passage 41 is closed. Figure 13As shown, when the user presses button 44, piston element 42 is pushed to the right into the interior of second air chamber 40, first elastic element 491 is compressed, and the volume of second air chamber 40 is compressed. Furthermore, one-way valve 46 prevents air from flowing out of first air passage 420 from the second air chamber 40, thus generating positive pressure airflow. After passing through third air passage 430, the airflow pushes upwards through air guide 47, separating second air passage 470 and air blocking part 48 on air guide 47. Gas flows sequentially through third air passage 430 and second air passage 470 into the gap between inflation unit and second support part 2212c, generating positive pressure to push second support part 2212c upwards, thereby realizing upward movement of movable unit 221. After air intake is complete, under the action of the second elastic element 492, the air guide 47 returns downward to the state where the air blocking part 48 extends into the second air passage 470, and the second air passage 470 is closed. At the same time, the first elastic element 491 drives the piston element 42 to rebound to the left. When the one-way valve 46 rebounds, there is a gap between it and the piston element 42, allowing outside air to enter the second air chamber 40 through the first air passage 420. After the first elastic element 491 and the piston element 42 rebound to their initial positions, pressing the button 44 again will generate positive pressure to push the second support part 2212c.

[0047] Alternatively, in some embodiments, the drive mechanism 222 may also include other linear motion mechanisms besides the inflation unit, such as ball screws, cylinders, etc.

[0048] Alternatively, in some embodiments, the movable component 2212 may be omitted, and the movable unit 221 may only include the first sealing component 2211. The first sealing component 2211 can cooperate with other components by magnetic attraction to realize the up-and-down movement of the first sealing component 2211. For example, the drive mechanism 222 may include a magnetic component, which may be disposed on the side of the second sealing component 24 opposite to the first sealing component 2211; the magnetic component and the first sealing component 2211 are magnets of the same polarity. When the magnetic component moves in the direction close to the first sealing component 2211 (i.e., moves upward), the first sealing component 2211 and the magnetic component are subjected to mutual repulsive force, causing the first sealing component 2211 to move in the direction away from the magnetic component (i.e., moves upward), thereby changing the volume of the first volume space 20 and the second volume space 21. Alternatively, in some other embodiments, the magnetic element may be disposed on the outer wall surface of the second housing 23 at a position corresponding to the first volume space 20. The magnetic element and the first sealing element 2211 are magnets of opposite polarities, thereby generating mutual attraction between the first sealing element 2211 and the magnetic element. When the magnetic element moves up and down along the outer wall surface of the second housing 23, it can drive the first sealing element 2211 to move up and down as well, thereby changing the volume of the first volume space 20 and the second volume space 21.

[0049] Please see Figure 5In some embodiments, the liquid supply unit 2 further includes a second liquid guide port 26. The first volume space 20 is connected to the first liquid guide port 11 through the second liquid guide port 26, and the second liquid guide port 26 is located above the movable unit 221. Specifically, both the first liquid guide port 11 and the second liquid guide port 26 are located above the movable unit 221. When the atomizer assembly is placed upright on the support surface, the suction port 15 of the atomizer 1 is facing upwards, with the side away from the support surface being the upper side and the side closer to the support surface being the lower side. That is, when the atomizer assembly is placed upright and the suction port 15 is facing upwards, the second liquid guide port 26 and the first liquid guide port 11 are located in the upper position. The liquid atomizing matrix in the first volume space 20 needs to overcome gravity to flow to the second liquid guide port 26. Therefore, the risk of leakage is relatively small, whether the atomizer assembly is in the supported state or during the replenishment process.

[0050] This utility model also provides an electronic atomizing device, which includes a power supply unit 5 and an atomizer assembly according to any of the above embodiments. The power supply unit 5 is connected to at least the atomizer 1 of the atomizer assembly and is used to provide power to the atomizing core 14 of the atomizer 1. The atomizing core 14 heats up when powered on, and the heated atomizing core 14 heats and atomizes the atomizing matrix to generate an aerosol, which escapes from the suction port 15 of the atomizer 1.

[0051] In some embodiments, the power supply unit 5 can also be connected to the drive mechanism 222 of the liquid supply unit 2 to provide power to the drive mechanism 222. The drive mechanism 222 includes a linear motion mechanism that can convert electrical energy into mechanical energy, such as a linear stepper motor, a lead screw and nut mechanism, etc.

[0052] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
