Description

Technical Field

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

[0002] Atomizers can be used to store liquid aerosol generating substrates such as electronic atomizing fluids, and when powered on, heat and atomize the liquid aerosol generating substrate to produce aerosols for users to inhale. Existing atomizers have an internal atomizing channel for delivering aerosols. The outlet and inlet of this atomizing channel are connected to the outside atmosphere, allowing the aerosols generated after heating and atomization to pass through the atomizing channel and be exited through the outlet for user inhalation.

[0003] The drawback of the existing technology is that the air outlet and air inlet of the atomizing air channel are always connected to the outside atmosphere. When the device is left unused for a long time, dust, impurities, pollutants, etc. from the outside may enter the device through the air inlet and air outlet of the atomizing air channel, causing the atomizer to be contaminated. Utility Model Content

[0004] The drawback of the existing technology is that the air outlet and air inlet of the atomizing air channel are always connected to the outside atmosphere. When the device is left unused for a long time, dust, impurities, pollutants, etc. from the outside may enter the device through the air inlet and / or air outlet of the atomizing air channel, causing the atomizing liquid to be contaminated and deteriorated, thus affecting the user's inhalation experience. The liquid aerosol generating matrix stored inside the device may also evaporate to the outside through the air inlet and / or air outlet of the atomizing air channel, or even leak from the air inlet and / or air outlet to the outside under pressure changes, resulting in the loss of liquid aerosol generating matrix and contamination of the device.

[0005] One solution is to install a sealing plug that is detachably connected to the air inlet or outlet of the atomizing airway. This sealing plug can be completely removed from the air inlet or outlet. However, this sealing plug needs to be frequently disassembled and reassembled, which is inconvenient to use and easy to lose.

[0006] One solution is to install a cap at the mouthpiece end or near the air inlet of the atomizer, which can close or open the air inlet or outlet. This can be achieved by flipping, pressing, sliding, or a combination of these methods. However, the cap structure occupies a large space, hindering device miniaturization. Furthermore, a single cap can only close the air inlet or outlet individually, offering limited protection against the connection between the atomizer's interior and the outside atmosphere. If two caps are used, multiple operations are required to simultaneously close both the air inlet and outlet, making the process complex.

[0007] To address the shortcomings of the aforementioned technologies, this invention provides an improved atomizer and electronic atomizing device, which allows for convenient operation to simultaneously open and close the air inlet and outlet of the first airway. When the device is left unused for an extended period, the atomizer provided by this invention prevents external dust, impurities, and contaminants from entering the device through the air inlet and outlet of the first airway, thus preventing contamination and deterioration of the atomizing liquid and affecting the user's inhalation experience. It also prevents the liquid aerosol generating matrix stored inside the device from evaporating to the outside through the air inlet and outlet of the first airway, or even leaking to the outside through the outlet under pressure changes, thereby preventing loss of the liquid aerosol generating matrix and contamination of the device. When using the atomizer provided by this utility model, users can conveniently operate the movable outer shell assembly to open the air inlet and outlet of the first airway during inhalation, thereby inhaling aerosol. When the device is not in use, the movable outer shell assembly can close the air inlet and outlet of the first airway, preventing the first airway from connecting with the external environment and ensuring the cleanliness and stability of the device.

[0008] To achieve the above objectives, some embodiments of this utility model provide an atomizer, including a housing assembly and an atomizing assembly. The atomizing assembly has a first air passage, an outlet end, and an inlet end opposite to the outlet end. The outlet end forms an air outlet, and the inlet end forms an atomizing air inlet. The first air passage is connected to external gas through the atomizing air inlet and the outlet. The housing assembly moves relative to the atomizing assembly between an open position and a closed position to simultaneously open or close the atomizing air inlet and the outlet.

[0009] In the open position, the atomizing air inlet and outlet are connected to the outside atmosphere, and users can inhale the aerosol overflowing from the outlet.

[0010] In the closed position, the atomizing air inlet and outlet are blocked, isolating the first air passage from the outside atmosphere, thus ensuring a clean and stable internal environment. The aerosol generation matrix inside the atomizer will not leak out, and external dust, impurities, etc. will not enter the first air passage.

[0011] In some embodiments, the first airway may be an atomizing airway for receiving atomized airflow.

[0012] In some embodiments, the housing assembly moves linearly between an open and closed position relative to the atomizing assembly. Users can easily open or close both the air inlet and outlet simultaneously, further enhancing ease of use.

[0013] In some embodiments, the housing assembly includes a mouthpiece with a first seal; the atomizing assembly includes an atomizing tube having an outlet end; in the closed position, the first seal abuts against the outlet end to close the air outlet. In some embodiments, the outer wall of the atomizing tube further includes a second seal abutting against the inner wall of the mouthpiece. As the housing assembly moves relative to the atomizing assembly between an open position and a closed position, the second seal remains abutting against the inner wall of the mouthpiece while moving relative to the mouthpiece, sealing the gap between the mouthpiece and the atomizing tube.

[0014] In some embodiments, the housing assembly includes a housing, and the atomizing assembly includes a bottom cover assembly. The outer wall of the bottom cover assembly has a third seal and a fourth seal. An air inlet is axially located between the third and fourth seals. In the closed position, the third and fourth seals abut against the housing to close the atomizing air inlet, isolating the atomizing air passage from the external environment. In the open position, the fourth seal moves axially away from the housing to open the atomizing air inlet, connecting the atomizing air passage to the outside atmosphere. Whether the third seal contacts the housing in the open position is not limited, as long as the atomizing air inlet can connect to the outside atmosphere.

[0015] In some embodiments, the first seal, second seal, third seal, and fourth seal may be made of an elastic material to enhance the sealing effect.

[0016] In some embodiments, the first, second, third, and fourth seals can be press-fitted to enhance the sealing effect. Specifically, the first seal can be press-fitted with the outlet end of the atomizing tube and the inner wall of the nozzle. Specifically, the second seal can be press-fitted with the inner wall of the nozzle. Specifically, in the closed position, the third and fourth seals can be press-fitted with the inner wall of the housing.

[0017] In some embodiments, the inner wall of the mouthpiece includes a protruding limiting portion, which has a first end axially close to the air outlet and a second end away from the air outlet. The outer wall of the atomizing tube includes a protruding limiting fitting portion, which has an upper edge axially close to the air outlet and a lower edge away from the air outlet. In the closed position, the lower edge of the limiting fitting portion abuts against the first end of the limiting portion; in the open position, the upper edge of the limiting fitting portion abuts against the second end of the limiting portion. This limiting structure ensures the stability of the atomizer during use, and provides a sensory cues to the user when the outer shell assembly reaches the open and closed positions.

[0018] In some embodiments, the inner wall of the mouthpiece also includes a raised latching portion, and the outer wall of the atomizing tube also includes a raised latching engagement portion. In the open position, the axial end of the latching engagement portion away from the first seal and the axial end of the latching portion close to the first seal abut against each other. With this structure, the latching engagement portion is difficult to disengage from its latching position, thus acting as a limiting element. This restricts the movement of the outer casing assembly between the closed and open positions, ensuring the stability of the atomizer during use.

[0019] In some embodiments, the atomizing assembly further includes a central tube forming a second air passage, which is independently configured with respect to the first air passage; preferably, the second air passage is disposed inside the first air passage. Since the second and first air passages are independent of each other, the normally open bottom of the second air passage does not affect the sealing of the first air passage, thus preventing leakage of atomizing liquid or condensate formed by atomization from clogging the second air passage when the second and first air passages are integrated.

[0020] In some embodiments, the second airway can be a starting airway, used to sense the suction airflow and thus activate the atomizer circuit. Therefore, the starting airway and the suction airway are independent of each other, avoiding situations where the starting airway cannot sense the suction airflow and cannot trigger the circuit. The starting airway is located inside the atomizing airway, saving space and facilitating the miniaturization of the atomizer.

[0021] In some embodiments, the bottom cover assembly includes a bottom cover and a screw that mates with the bottom cover, with an atomizing air inlet radially opened on the bottom cover. During liquid injection, the bottom cover can be removed, aerosol matrix can be added, and then the bottom cover can be pressed between the screw and the outer shell to seal the liquid storage chamber.

[0022] In some embodiments, the screw has a radially formed inner through hole at the position corresponding to the air inlet, and an alignment groove is formed at the end of the inner through hole near the air inlet. The diameter of the alignment groove is larger than the diameter of the air inlet. Through the alignment groove at the air inlet position of the screw, the bottom cover does not need to be aligned radially with the screw after liquid injection, and the air inlet can still smoothly connect to the outside atmosphere and the atomizing air passage. This makes the liquid filling and capping process more convenient, and also facilitates industrial production; the component can be used normally even if high precision is not required during production.

[0023] Some embodiments of this invention also provide an electronic atomizing device, including the atomizer provided in any embodiment of this invention. The atomizer is electrically connected to a screw and a power supply assembly, so that the aerosol generating matrix contained inside the atomizer is atomized into an aerosol for the user to inhale.

[0024] This invention offers at least the following advantages: the air inlet and outlet of the atomizing airway can be opened or closed simultaneously. When the air inlet and outlet are closed, the atomizing airway of the atomizer is completely isolated from the outside atmosphere, preventing dust, impurities, and pollutants from entering the device through the air inlet and outlet, or preventing the liquid aerosol generating matrix stored inside the device from evaporating to the outside through the air inlet and outlet, or even leaking to the outside through the outlet under conditions of temperature or pressure changes. The cleanliness of the atomizer and electronic atomization device is improved, the aerosol generating matrix is ​​less prone to deterioration, and user health is guaranteed. Furthermore, users can easily switch between the open and closed states of the atomizing airway, resulting in a better user experience. Attached Figure Description

[0050] Figure 1 , Figure 2 and Figure 3The diagram illustrates an atomizer according to some embodiments of the present invention, including a housing assembly 1 and an atomizing assembly 2. The atomizing assembly 2 has an atomizing airway 21, and further includes an atomizing tube 22, a central tube 24, and a heating base tube 26. The atomizing airway 21 is formed by the inner walls of the atomizing tube 22, the heating base tube 26, and the central tube 24. The atomizing tube 22 has an outlet end 221, which forms a sensing air outlet 2201. The atomizing assembly 2 also includes a bottom cover assembly 23, which includes a bottom cover 233 and a screw 234. The side wall of the bottom cover 233 has an external through hole, which forms an air inlet 2301 and an air intake channel. The housing assembly 1 includes a mouthpiece 11, which forms an air outlet 1101. The activation airway 25 is connected to external gas through the sensing air inlet 2342 and the air outlet 1101. The atomizing air duct 21 is connected to the external gas through the atomizing air inlet 2301 and the air outlet 1101. The inner wall of the atomizing tube 22 and the outer wall of the heating base tube 26 form a liquid storage chamber, which can store liquid aerosol generation matrix. The aerosol generation matrix is ​​used to be atomized to form an aerosol for the user to inhale.

[0051] Combination Figure 2 and Figure 3 The outer shell assembly 1 can move relative to the atomizing assembly 2 between an open position and a closed position to simultaneously open or close the air inlet 2301 and the air outlet 1101. Preferably, the outer shell assembly 1 moves relative to the atomizing assembly 2 between an open position and a closed position, simultaneously opening or closing the air inlet 2301, the air outlet 1101, and the sensor-activated air outlet 2201. The user moves the outer shell assembly 1 to the open position relative to the atomizing assembly 2 to inhale. During inhalation, external gas enters the atomizer from the air inlet 2301 along the air inlet channel. The aerosol generating matrix inside the liquid storage chamber is atomized into an aerosol through methods including but not limited to resistance atomization, electromagnetic atomization, infrared atomization, microwave atomization, ultrasonic atomization, laser atomization, and two-phase flow atomization. The aerosol passes through the atomizing air channel and flows out from the air outlet 1101. The user inhales the aerosol through the mouthpiece 11 and obtains a sense of satisfaction. When not in use for a long time or when vaping is stopped, the user moves the outer shell assembly 1 linearly relative to the atomizing assembly 2 to the closed position, so that the air inlet 2301 and the air outlet 1101 are closed at the same time, and the atomizing airway is isolated from the outside atmosphere, thereby ensuring a clean and stable internal environment. The aerosol generation matrix inside the atomizer will not leak out or deteriorate easily, and external dust, impurities, etc. will not enter the atomizing airway.

[0052] In some embodiments, the housing assembly moves linearly between an open and closed position relative to the atomizing assembly. Users can easily open or close both the air inlet and outlet simultaneously, further enhancing ease of use.

[0053] Specifically, the movement of the outer shell assembly 1 relative to the atomizing assembly 2 between the open and closed positions can be axial. Understandably, the atomizer can be generally cylindrical or cuboid in shape, and "axial" can be interpreted as the axial direction of the cylinder or the length direction of the cuboid. Understandably, "axial" can be interpreted as the length direction of the atomizer in normal use, or the axial direction of the center tube 24, or the axial direction of the heating element 26, or the axial direction of the atomizing tube 22.

[0054] Specifically, in some embodiments, the outer casing assembly 1 includes a nozzle 11, which includes a first seal 111; the atomizing assembly 2 includes an atomizing tube 22, which has an outlet end 221, and the outlet end 221 and the atomizing tube 22 are integrally formed; in the closed position, the first seal 111 and the outlet end 221 abut against each other to close the air outlet 1101. Here, the specific structure and material of the first seal 111 are not limited, as long as it can close the air outlet 1101. For example, the first seal 111 may include a generally annular structure that seals the outer wall of the outlet end 221 in the closed position. The central portion of the first seal 111 has a sealing structure that corresponds to the central portion of the outlet end 221 in the closed position, closing the air outlet 1101 and simultaneously sealing the sensing air outlet 2201 to prevent dust from entering or accidental activation of the electronic atomizing device. For example, the first seal 111 may be made of elastic materials such as silicone or plastic to enhance the sealing effect. For example, the first seal 111 can be interference-fitted with the nozzle 11 and the outlet end 221 of the atomizing tube 22 to enhance the sealing effect.

[0055] In some embodiments, the outer wall of the atomizing tube 22 further includes a second seal 222, which abuts against the inner wall of the nozzle 11, isolating the liquid storage chamber from the gap between the atomizing tube 22 and the nozzle 11, preventing leakage of the aerosol generation matrix in the liquid storage chamber, contamination, or corrosion of the gap between the atomizing tube 22 and the nozzle 11. When the outer shell assembly 1 moves axially relative to the atomizing assembly 2 between the open and closed positions, the second seal 222 always remains abutting against the inner wall of the nozzle 11 and moves axially relative to the outer shell assembly 1 along the inner wall of the nozzle 11. For example, the second seal 222 can be an annular structure and can be made of elastic materials such as silicone or plastic to enhance the sealing effect. For example, the second seal 222 can be interference-fitted with the nozzle 11 to enhance the sealing effect.

[0056] In some embodiments, the housing assembly 1 includes a housing 12, and the atomizing assembly 2 includes a bottom cover assembly 23. The outer wall of the bottom cover assembly 23 has a third seal 231 and a fourth seal 232. The air inlet 2301 is axially located between the third seal 231 and the fourth seal 232. When the housing assembly 1 is in the closed position, the third seal 231 and the fourth seal 232 abut against the housing 12 to close the air inlet 2301, thus isolating the atomizing air passage 21 from the external environment. For example, the third seal 231 and the fourth seal 232 may be press-fitted with the housing 12 to enhance the sealing effect. When the housing assembly 1 is in the open position, the fourth seal 232 and the air inlet 2301 are axially moved away from the housing 12 to open the air inlet 2301, thus connecting the atomizing air passage 21 to the outside atmosphere. In the open position, it is not limited whether the third seal 231 is in contact with the housing 12, as long as the air inlet 2301 can be connected to the outside atmosphere. For example, the third seal 231 and the fourth seal 232 may be annular structures, and may be made of elastic materials such as silicone or plastic to enhance the sealing effect. For example, the outer walls of the third seal 231 and the fourth seal 232 may have flanges to enhance the sealing effect.

[0057] In some embodiments, the atomizing assembly 2 further includes a central tube 24 for forming an activation airway 25. The activation airway 25 is equipped with a sensor that detects the suction action during inhalation, thereby activating the atomizer circuit and causing the aerosol generation matrix to be atomized into an aerosol. Understandably, the sensor may be, but is not limited to, a flow sensor, a pressure sensor, etc.

[0058] In some embodiments, the central tube 24 is disposed inside the atomizing airway 21, forming the activation airway 25. The activation airway 25 and the atomizing airway 21 are independent of each other, and the bottom of the activation airway 25 is normally open without affecting the sealing of the atomizing airway 21. The independent arrangement of the activation airway 25 and the atomizing airway 21 can avoid situations where the atomizing liquid or the condensate formed by atomization leaks out and blocks the activation airway, or the activation airway cannot sense the suction airflow and cannot be triggered when the activation airway and the atomizing airway are integrated. The activation airway 25 is disposed inside the atomizing airway 21, which can save space and is conducive to the miniaturization of the atomizer.

[0059] Reference Figure 11 The airflow direction in the activation airway 25 is shown by the dashed arrow. When the user inhales, the gas flows in from the induction air inlet 2342, passes through the central tube 24, flows out from the induction air outlet 2201, and finally flows out of the atomizer from the air outlet 1101. The airflow direction in the atomization airway 21 is shown by the solid arrow. The gas flows in from the atomization air inlet 2301 on the side wall of the bottom cover, passes through the heating base tube 26, flows out from the atomization air outlet 2202, merges with the airflow from the activation airway, and flows out of the atomizer from the air outlet 1101.

[0060] The aerosol generation matrix inside the liquid storage chamber of the atomizer is atomized into aerosol through methods including but not limited to resistance atomization, electromagnetic atomization, infrared atomization, microwave atomization, ultrasonic atomization, laser atomization, and two-phase flow atomization.

[0061] In some embodiments, the atomizer employs resistive atomization. The atomization component 2 further includes a heating element 27, through which the aerosol generating matrix is ​​heated and atomized into an aerosol for inhalation by the user. Specifically, the heating element 27 may include a metal heating element, a ceramic heating element, a quartz heating element, a glass heating element, etc.; the shape of the heating element 27 can be various structures such as block, sheet, mesh, cylindrical, ring, layered, etc. The heating element 27 is in communication with the liquid storage chamber to atomize the aerosol generating matrix, and the direction of communication is not limited. In some embodiments, the heating element 27 is electrically connected to the power supply component. For example, the heating element 27 is electrically connected to the screw 234 through electrode pins. When the user uses the atomizer, the screw 234 is electrically connected to the power supply component, thereby supplying power to the heating element 27.

[0062] In some embodiments, the atomizing component 2 further includes a liquid guide (not shown) for storing a portion of the aerosol generating matrix and guiding the aerosol generating matrix from the liquid storage chamber to the heating element 27 for atomization.

[0063] refer to Figure 4 In some embodiments, the inner wall of the mouthpiece 11 includes a protruding limiting portion 112, which includes a first end 1121 axially approaching the sensing air outlet 2201 and a second end 1122 away from the sensing air outlet 2201. The outer wall of the atomizing tube 22 includes a protruding limiting fitting portion 223, which includes an upper edge 2231 axially approaching the sensing air outlet 2201 and a lower edge 2232 away from the sensing air outlet 2201. When the outer shell assembly 1 is in the closed position, the lower edge 2231 of the limiting fitting portion 223 abuts against the first end 1121 of the limiting portion 112. When the outer shell assembly 1 is in the open position, the upper edge 2231 of the limiting fitting portion 223 abuts against the second end 1122 of the limiting portion 223. This limiting structure ensures the stability of the atomizer during use and provides a sensory cues to the user when the outer shell assembly 1 reaches the open or closed position.

[0064] In some embodiments of this utility model, there can be more than one limiting part 112 and limiting mating part 223; specifically, multiple limiting parts 112 are symmetrically distributed on the inner peripheral wall of the nozzle 11, and multiple limiting mating parts 223 are symmetrically distributed on the outer peripheral wall of the atomizing tube 22, which is easy for industrial production and assembly.

[0065] Reference Figure 9 and Figure 10 In some embodiments, the inner wall of the nozzle 11 further includes a protruding latching portion 113, and the outer wall of the atomizing tube 22 further includes a protruding latching engagement portion 224. When the outer shell assembly 1 is in the open position, the axial end of the latching engagement portion 224 of the atomizing tube 22 away from the first seal 111 abuts against the axial end of the latching portion 113 of the nozzle 11 near the first seal 111, thus serving as a limiting element. When the outer shell assembly 1 is in the closed position, the first seal 111 abuts against the outlet end 221 of the atomizing tube 22, thus serving as a limiting element. With the above structure, the latching engagement portion 224 is difficult to disengage from the latching portion 113, thereby limiting the movement of the outer shell assembly 1 between the closed and open positions, ensuring the stability of the atomizer in use. Understandably, there can be more than one snap-fit ​​part 113 and snap-fit ​​mating part 224; specifically, multiple snap-fit ​​parts 113 can be symmetrically arranged on the inner wall of the nozzle 11, and correspondingly, multiple snap-fit ​​mating parts 224 can be symmetrically arranged on the outer wall of the atomizing tube 22, so as to facilitate industrial production and atomizer assembly.

[0066] Reference Figure 4 , Figure 5 and Figure 6 In some embodiments, the first seal 111 may include a generally annular structure, and the central part of the first seal 111 has a sealing structure. When the housing assembly 1 is in the closed position, the sealing structure can close the air outlet 1101, so that the atomizing air passage 21 is isolated from the outside atmosphere; when the housing assembly 1 is in the open position, the sealing structure can open the air outlet 1101, so that the atomizing air passage 21 is connected to the outside atmosphere.

[0067] Reference Figure 2 , Figure 7 and Figure 8 In some embodiments, the bottom cover assembly 23 includes a bottom cover 233 and a screw 234 assembled with the bottom cover 233. The bottom cover 233 has a radially open outer through hole, which forms the air inlet 2301. The screw 234 has a radially open inner through hole 2340 corresponding to the position of the air inlet 2301. The end of the inner through hole 2340 near the air inlet 2301 has an alignment groove 2341, the diameter of which is larger than the diameter of the air inlet 2301. During liquid injection, the bottom cover 233 can be removed from the atomizer, and aerosol can be added to generate the matrix. After the injection is completed, the bottom cover 233 is pressed between the screw 234 and the outer shell 12 to seal the liquid storage chamber, facilitating liquid injection.

[0068] Understandably, the atomizer can be roughly cylindrical in shape. "Radial" can be interpreted as the radial direction of the cylinder, or the radial direction of the center tube 24, or the radial direction of the heating base tube 26, or the radial direction of the atomizing tube 22, or the radial direction of the bottom cover assembly.

[0069] By using the alignment groove 2341 corresponding to the position of the screw 234 at the air inlet 2301, the bottom cover 233 does not need to be precisely aligned with the screw 234 in the radial position after liquid injection. The air inlet 2301 can also smoothly connect to the outside atmosphere and the atomizing air channel 21, making the liquid injection capping process more convenient and achieving a foolproof effect. It is also easy for industrial production, and can be used normally even when the component does not require very high precision during production. Specifically, when capping, the user can move the bottom cover 233 onto the screw 234 and tightly engage it by rotating or directly applying pressure.

[0070] Reference Figure 2 and Figure 12 Some embodiments of this utility model also provide an electronic atomizing device, including the atomizer of any of the above embodiments. In some embodiments of this utility model, the electronic atomizing device further includes a power supply component. The atomizer and the power supply component are electrically connected. The power supply component supplies power to the electronic atomizing device, causing the aerosol-generating matrix contained within the atomizer to be atomized into an aerosol for the user to inhale. In some embodiments of this utility model, the atomizer and the power supply component are detachably connected. Specifically, the atomizer and the power supply component can employ connection structures such as snap-fit, screw connection, plug-in, riveting, etc., to ensure a secure connection between the atomizer and the power supply component. More specifically, the atomizer can be connected to the power supply component via a screw 234. Even more specifically, the outer wall of the screw 234 can also have external threads, allowing it to be connected to the power supply component via the external threads.

[0071] This invention has at least the following beneficial effects: The air inlet 2301 and air outlet 1101 of the atomizing airway 21 can be opened or closed simultaneously. When the air inlet 2301 and air outlet 1101 are closed, the atomizing airway 21 of the atomizer is completely isolated from the outside atmosphere, preventing dust, impurities, pollutants, etc. from entering the device through the air inlet 2301 and air outlet 1101, or preventing the liquid aerosol generating matrix stored inside the device from evaporating to the outside through the air inlet 2301 and air outlet 1101, or even leaking to the outside from the air outlet under conditions of temperature and pressure changes. The cleanliness of the atomizer and electronic atomization device is improved, the aerosol generating matrix is ​​less likely to be lost or deteriorated, the user's health is guaranteed, the atomizer is miniaturized, and the user can easily switch between the open and closed states of the atomizing airway, resulting in a better user experience.
