atomizing device

Abstract

This application discloses an atomizing device, equipped with a toggle switch for controlling the connection between a first liquid chamber and a second liquid chamber to prevent leakage, and for controlling the connection between the air inlet and the first and second air passages to adjust the air intake volume. The toggle switch has three states: When the operating part is in the first position, the toggle switch is in its initial state, sealing the outlet of the first liquid chamber and interrupting the connection between the first and second liquid chambers to prevent leakage. At this time, the toggle switch also blocks the air intake passage, preventing external airflow from entering the atomizing channel and thus eliminating the risk of coil clogging. When the toggle switch is pushed to the second or third position, the toggle switch opens the outlet, connecting the first and second liquid chambers, allowing for continuous liquid supply for the user's atomizing action. By adjusting the operating part to the second or third position, the corresponding first and / or second air passage can be selected to connect with the air inlet as the air intake channel, matching the air intake volume for different power levels.

Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, specifically to an atomization device. Background Technology

[0002] During long-distance transportation or when not in use for extended periods, electronic atomizing devices often experience leakage. Because the liquid reservoir is constantly connected to the atomization channel within the atomizing tube via the liquid inlet of the atomizing core, the reservoir contains a large amount of atomizing matrix. Under the influence of internal and external pressures, such as increased temperature leading to excessive internal pressure, or incorrect placement, the atomizing matrix can leak from the reservoir into the atomization channel through the liquid inlet on the atomizing core. Since the atomization channel is connected to the outside via the air inlet, the atomizing matrix eventually flows out through the air inlet, causing leakage and impacting the user experience. Furthermore, the matching of the atomizing device's power and airflow directly affects the aerosol's temperature, flavor, and atomization efficiency. Both need to be adjusted collaboratively to avoid issues such as clogging, overheating, or insufficient aerosol. Currently, there is no structural or technical solution that can simultaneously address leakage caused by the liquid inlet of the atomization channel and the adjustment of the airflow within the atomization channel. Summary of the Invention

[0003] This application provides an atomizing device with a toggle switch to solve the problem that the atomizing matrix will flow out through the air inlet, causing leakage of the atomizing device and affecting the user experience. At the same time, the toggle switch is also used to adjust the air intake of the atomizing device to match the corresponding power to start the atomizing core.

[0004] In some embodiments, the atomizing device includes: case; The atomizing core is installed inside the housing and has a liquid inlet and an atomizing channel; The first liquid tank is equipped with a liquid outlet; The second liquid tank is connected to the atomizing core through the liquid inlet, and the first liquid tank is connected to the second liquid tank through the liquid outlet; The first airway and the second airway are both connected to the atomizing channel; A toggle switch, the toggle switch including a connected operating part and a moving part, the moving part having an air inlet, the operating part being at least partially located on the surface of the housing, and the moving part being located inside the housing; When the operating part is in the first position of the housing, the moving part blocks the liquid outlet, and the moving part simultaneously blocks the first air passage and the second air passage; When the operating part is in the second position of the housing, the moving part releases the blockage of the liquid outlet, and the air inlet is connected to the first air passage, while the second air passage is still blocked by the moving part; When the operating part is in the third position of the housing, the moving part releases the blockage of the liquid outlet, and the air inlet connects to the second air passage.

[0005] In some embodiments, the operating part and the moving part are perpendicular, and the operating part and the moving part move in the same direction.

[0006] In some embodiments, the moving part includes a first segment and a second segment, wherein the area of ​​at least a portion of the cross-section of the first segment is the same as the area of ​​the liquid outlet, and the second segment is provided with the air inlet; When the operating unit moves to the first position in the moving space, the first segment is inserted into the liquid outlet to disconnect the connection between the first liquid tank and the second liquid tank, and the second segment simultaneously blocks the first air passage and the second air passage.

[0007] In some embodiments, when the operating part moves to the second position, the first segment moves out of the liquid outlet, and the air inlet is connected to the first air passage, while the second air passage is still blocked by the second segment.

[0008] In some embodiments, when the operating part moves to the third position, the first segment moves out of the liquid outlet, and the air inlet connects to the second air passage, with the first air passage being blocked by the second segment.

[0009] In some embodiments, the first airway and the second airway have different diameters.

[0010] In some embodiments, when the operating part moves to the third position, the first segment moves out of the liquid outlet, and the air inlet is simultaneously connected to the first air passage and the second air passage.

[0011] In some embodiments, at least a portion of the first segment is a transition segment, and the cross-sectional radius of the first segment increases from the end face toward the second segment.

[0012] In some embodiments, the length of the first segment is greater than the travel distance of the operating part.

[0013] In some embodiments, a sealing ring is fitted onto the outer surface of the first segment.

[0014] In some embodiments, the atomizing device further includes a main airway, one end of which is connected to the atomizing channel, and the other end of which is connected to both the first airway and the second airway.

[0016] In some embodiments, a liquid channel is provided between the first liquid tank and the second liquid tank, and a liquid blocking plate is provided in the liquid channel.

[0017] The atomizing device provided in this embodiment is equipped with a toggle switch, which has at least two functions: controlling the connection between the first and second liquid chambers to prevent leakage, and controlling the connection between the air inlet and the first and second air passages to adjust the air intake. Specifically, the toggle switch has three states, corresponding to three positions of the operating part on the outer surface of the housing: a first position, a second position, and a third position. When the operating part is in the first position, the toggle switch is in its initial state, which seals the outlet of the first liquid chamber, interrupting the connection between the first and second liquid chambers, thereby achieving a leak-proof effect. At this time, the toggle switch also blocks the air intake passage, preventing external airflow from entering the atomizing channel, thus preventing the user from inhaling and eliminating the risk of coil clogging. When the toggle switch is pushed to the second or third position, the toggle switch opens the outlet, connecting the first and second liquid chambers, allowing for a continuous supply of liquid for the user's inhalation. Simultaneously, by adjusting the position of the operating unit relative to the second and third positions, the corresponding first and / or second air passages can be selected to connect with the air inlet as air intake channels to match the air intake volume of different power levels.

[0021] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0022] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0023] Please refer to Figures 1 to 8In some embodiments, an atomizing device 100 is provided. The atomizing device 100 may include a housing 10 and a mouthpiece 70. The housing 10 contains an atomizing core 50, a first liquid tank 30, and a second liquid tank 40. The first liquid tank 30 and the second liquid tank 40 store atomizing matrix. The second liquid tank 40 is connected to the atomizing core 50, providing the atomizing matrix to the atomizing core 50 to generate an aerosol, which is then inhaled by the user through the mouthpiece 70. When the atomizing matrix in the second liquid tank 40 is consumed, the first liquid tank 30 replenishes the atomizing matrix to the second liquid tank 40.

[0024] It should be noted that the atomizing matrix is ​​a matrix capable of releasing volatile compounds that can form aerosols, and can be in solid, liquid, or semi-solid form, for example, fine particles of gaseous substances that are typically liquid or solid at room temperature. According to the atomizing device 100 of this application, the aerosol generated by the atomizing matrix can be visible or invisible vapor or gas. This application's embodiments are described using a liquid atomizing matrix, which will be referred to as "liquid" below.

[0025] Please see Figures 2-3 The atomizing device 100 includes a housing 10; an atomizing core 50 installed inside the housing 10, having a liquid inlet 510 and an atomizing channel 520; a first liquid chamber 30 having a liquid outlet 31; a second liquid chamber 40 connected to the atomizing core 50 via the liquid inlet 510, and the first liquid chamber 30 connected to the second liquid chamber 40 via the liquid outlet 31; a first air passage 61 and a second air passage 62, both of which are connected to the atomizing channel 520; and a toggle switch 20, which includes an operating part 22 and a moving part 21 connected together. The moving part 21 has an air inlet 2121, and the operating part 22 has at least one air inlet 2121. Part of the moving part 21 is located on the surface of the housing 10, and the moving part 22 is located inside the housing 10. When the operating part 22 is in the first position of the housing 10, the moving part 21 blocks the liquid outlet 31 and simultaneously blocks the first air passage 61 and the second air passage 62. When the operating part 22 is in the second position of the housing 10, the moving part 21 releases the blockage of the liquid outlet 31, and the air inlet 2121 connects to the first air passage 61, while the second air passage 62 is still blocked by the moving part 21. When the operating part 22 is in the third position of the housing 10, the moving part 21 releases the blockage of the liquid outlet 31, and the air inlet 2121 connects to the second air passage 62.

[0026] It should be noted that you should refer to [link / reference]. Figures 3-4 The toggle switch 20 includes an integrally connected operating part 22 and a moving part 21. The moving part 21 has an air inlet 2121. The operating part 22 is at least partially exposed on the surface of the housing 10 for the user to toggle, while the moving part 21 is entirely housed inside the housing 10. Depending on the toggle position of the operating part 22 on the housing 10, the toggle switch 20 has three operating positions, which simultaneously control the sealing of the liquid path and the opening and closing of the air passage. First position (initial state, power off and sealed): e.g. Figures 6-7 As shown, the moving part 21 blocks the outlet 31 of the first liquid chamber 30, cutting off the liquid channel 41 between the first liquid chamber 30 and the second liquid chamber 40; at the same time, the moving part 21 completely blocks the first air passage 61 and the second air passage 62, so that the external airflow cannot enter the atomizing core 50 and the atomizing device 100 cannot draw in.

[0027] Second position (usage mode, low power, low intake): e.g. Figures 4-5 As shown, the moving part 21 detaches from the liquid outlet 31, and the liquid channel 41 between the first liquid tank 30 and the second liquid tank 40 remains open, allowing the first liquid tank 30 to continuously replenish the atomizing matrix to the second liquid tank 40. Additionally, the air inlet 2121 in the moving part 21 connects to the first air passage 61, while the second air passage 62 remains continuously blocked.

[0028] Third position (usage mode, high power, large intake): such as... Figures 2-3 As shown, the moving part 21 keeps the liquid outlet 31 open, and the liquid channel 41 between the first liquid tank 30 and the second liquid tank 40 remains open; the air inlet 2121 of the moving part 21 is connected to at least the second air channel 62.

[0029] The atomizing device 100 of this embodiment includes a housing 10, an atomizing core 50, a first liquid tank 30, a second liquid tank 40, a first air passage 61, a second air passage 62, and a toggle switch 20. The toggle switch 20 is divided into an operating part 22 and a moving part 21, and has three positions: When the toggle switch 20 is in the first position, the moving part 21 blocks the liquid outlet 31 of the liquid tank and simultaneously blocks the first air passage 61 and the second air passage 62, thereby achieving liquid tank isolation to prevent leakage and air lock to prevent core clogging. When the toggle switch 20 is in the second or third position, the liquid passage between the first liquid tank 30 and the second liquid tank 40 is opened, and it can be connected to the first air passage 61 and / or the second air passage 62 respectively, adjusting the air intake in stages to match the output power of the atomizing core 50 and achieve high or low power atomization.

[0030] In some embodiments, the operating part 22 and the moving part 21 are perpendicular, and the operating part 22 and the moving part 21 move in the same direction.

[0031] It should be noted that the toggle switch 20 is integrally injection molded from the operating part 22 and the moving part 21. The operating part 22 is perpendicular to the moving part 21, and the two slide laterally along the housing 10 synchronously.

[0032] Furthermore, the operating part 22 is exposed outside the housing 10, and the user's finger can flick the operating part 22 horizontally or vertically. Since the operating part 22 is perpendicular to the moving part 21 and the movement direction of the operating part 22 and the moving part 21 is the same, the pushing force applied by the user to the operating part 22 can be directly transmitted along the movement direction of the moving part 21. There is no force loss in the force transmission process, which can improve the smoothness of the user's flicking.

[0033] In some embodiments, the moving part 21 includes a first segment 211 and a second segment 212. The area of ​​at least a portion of the cross-section of the first segment 211 is the same as the area of ​​the liquid outlet 31, and the second segment 212 is provided with an air inlet 2121. When the operating part 22 moves to the first position in the moving space, the first segment 211 is inserted into the liquid outlet 31, disconnecting the connection between the first liquid tank 30 and the second liquid tank 40, and the second segment 212 simultaneously blocks the first air passage 61 and the second air passage 62.

[0034] It should be noted that the cross-sectional dimensions of the first segment 211 are at least partially adapted to the liquid outlet 31. When the operating part 22 is in the first position, the first segment 211 is inserted into the liquid outlet 31 to form a seal, thereby isolating the liquid passage between the first liquid chamber 30 and the second liquid chamber 40. At this time, the second segment 212 simultaneously blocks the first air passage 61 and the second air passage 62. The atomizing core 50 cannot be connected to the outside air, and there is no airflow within the atomizing device 100, so heating cannot be performed.

[0035] In some embodiments, when the operating part 22 moves to the second position, the first segment 211 moves out of the liquid outlet 31, and the air inlet 2121 connects to the first air passage 61, while the second air passage 62 is still blocked by the second segment 212.

[0036] It should be noted that when the operating unit 22 is in the second position, the first section 211 is completely removed from the liquid outlet 31, and the liquid channel 41 between the first liquid tank 30 and the second liquid tank 40 remains open, with the first liquid tank 30 continuously supplying the atomizing matrix to the second liquid tank 40; the air inlet 2121 in the moving unit 21 connects to the first air passage 61, while the second air passage 62 remains blocked. Understandably, at this time, the atomizing core 50 is only connected to external air through the first air passage 61, resulting in a small air intake. Therefore, the atomizing core 50 heats the atomizing matrix with low power output, resulting in less aerosol gas formation.

[0037] In some embodiments, when the operating part 22 moves to the third position, the first segment 211 moves out of the liquid outlet 31, and the air inlet 2121 connects to the second air passage 62, and the first air passage 61 is blocked by the second segment 212.

[0038] It should be noted that the diameters of the first air passage 61 and the second air passage 62 are different, with the diameter of the second air passage 62 being larger than that of the first air passage 61, meaning that the air intake volume of the second air passage 62 is greater than that of the first air passage 61. Additionally, the diameter of the air inlet 2121 is smaller and can only connect to either the first air passage 61 or the second air passage 62.

[0039] When the operating unit 22 is in the third position, the first section 211 is also completely removed from the liquid outlet 31. The liquid channel 41 between the first liquid tank 30 and the second liquid tank 40 remains open, and the first liquid tank 30 continuously replenishes the atomizing matrix to the second liquid tank 40. The air inlet 2121 in the moving part 21 connects to the second air passage 62, while the first air passage 61 is continuously blocked. Understandably, at this time, the atomizing core 50 is connected to the external air only through the second air passage 62, resulting in a large air intake. At this time, the atomizing core 50 heats the atomizing matrix with high power, which can provide more aerosol and increase the aerosol concentration.

[0040] In some embodiments, when the operating part 22 moves to the third position, the first segment 211 moves out of the liquid outlet 31, and the air inlet 2121 is simultaneously connected to the first air passage 61 and the second air passage 62.

[0041] It should be noted that at this time, the diameters of the first airway 61 and the second airway 62 can be the same or different. The diameter of the air inlet 2121 is larger. When the operating part 22 moves to the third position, the air inlet 2121 can simultaneously cover the air inlet ends of the first airway 61 and the second airway 62. The first airway 61 and the second airway 62 are simultaneously connected to the outside air for synchronous air intake, and the total air intake reaches the maximum value, which is suitable for ultra-high power atomization requirements and meets the application scenarios of strong concentration aerosols.

[0042] In summary, the atomizing device 100 of this embodiment can simultaneously achieve the sealing of the liquid passage and the switching of multiple air intake levels through a single toggle switch 20, eliminating the need for separate liquid valves and air adjustment sliders, simplifying the internal structure of the atomizing core 50, and facilitating the miniaturization of the atomizing device 100. Furthermore, based on the relative position of the toggle switch 20 and the housing 10, the atomizing device 100 can achieve physical isolation between the atomizing core 50 and the liquid storage chamber when idle, fundamentally solving the leakage problems during transportation and static storage, while simultaneously locking the air intake to prevent dry burning. During use, the output power can be precisely matched through staged air intake via the first airway 61 and / or the second airway 62 to optimize the atomized flavor.

[0043] In some embodiments, at least a portion of the first segment 211 is a transition segment, and the cross-sectional radius of the first segment 211 increases from the end face toward the second segment 212.

[0044] It should be noted that the size of at least the end face of the first segment 211 is smaller than the size of the outlet 31, making it easier to insert the switch 20 into the first liquid tank 30. In addition, when the operating part 22 moves to the first position, the larger diameter end of the first segment 211 contacts the inner wall surface of the outlet 31 and forms an interference fit, completely sealing the outlet 31.

[0045] In some embodiments, the length of the first segment 211 is greater than the travel distance of the operating part 22.

[0046] It should be noted that the length of the first segment 211 is greater than the travel distance of the operating part 22. This ensures that the first segment 211 remains partially in the second liquid tank 40 or flush with the bottom surface during the switching of the toggle switch 20 at any position, thus preventing it from completely exiting the second liquid tank 40 and causing leakage.

[0047] In some embodiments, a sealing ring 213 is fitted onto the outer surface of the first segment 211.

[0048] It should be noted that the outer surface of the second liquid tank 40 is provided with a hole or groove structure, and the sealing ring 213 is sleeved on the first section 211 of the toggle switch 20. During the switching of any position of the operating part 22, the first section 211 can move in the second liquid tank 40 to completely seal. Furthermore, the sealing ring 213 can be made of fluororubber, which is corrosion resistant and ensures that the seal will not fail after long-term reciprocating sliding.

[0049] In some embodiments, the atomizing device 100 further includes a main airway 60, one end of which is connected to the atomizing channel 520, and the other end is simultaneously connected to the first airway 61 and the second airway 62.

[0050] The atomizing core 50 includes an atomizing tube 51, a liquid guide 53, and a heating element 52. The liquid guide 53 and the heating element 52 are disposed inside the atomizing tube 51. A liquid inlet 510 is provided on the tube wall of the atomizing tube 51, and the internal cavity structure forms an atomizing channel 520. The main air passage 60 is formed in the internal space of the housing 10. One end of the main air passage 60 is connected to the atomizing channel 520, and the other end is connected to both the first air passage 61 and the second air passage 62.

[0051] It should be noted that the space required for the first air passage 61 and the second air passage 62 to connect to the atomization channel 520 is relatively large. Setting a main air passage 60 inside the housing 10 to connect the first air passage 61 and the second air passage 62 can reduce the space distribution inside the housing 10.

[0052] Preferably, the two ends of the first air passage 61 and the second air passage 62 are aligned and arranged side by side. Specifically, the first air passage 61 and the second air passage 62 adopt an integrally formed groove structure with flush end faces, so that the airflow connection is not offset when switching gears, and there are no problems such as air leakage or abnormal noise.

[0053] In some embodiments, such as Figure 9 As shown, a liquid channel 41 is provided between the first liquid tank 30 and the second liquid tank 40, and a liquid blocking plate 42 is provided in the liquid channel 41.

[0054] In some embodiments, the liquid channel 41 is disposed within the internal space of the second liquid chamber 40, i.e., the liquid channel 41 and the second liquid chamber 40 are integrally formed. Liquid blocking plates 42 are spaced apart and arranged in the liquid channel 41, forming a reverse groove, which is located on the side of the second liquid chamber 40 near the outlet 31 of the first liquid chamber 30. The inlet of the second liquid chamber 40 is also the inlet of the liquid channel 41. It should be noted that the integral formation of the liquid channel 41 and the second liquid chamber 40 can reduce the volume of the atomizing device 100 and provide more installation space for other components of the atomizing device 100.

[0055] In some embodiments, the liquid blocking plate 42 forms one or more bends in the liquid channel 41, and the flow direction of the liquid through the reverse groove changes at least once, so that the actual path of the liquid from the inlet to the outlet is longer than a straight line, thereby blocking the liquid flow and reducing the risk of liquid leakage from the air inlet or outlet of the atomizing core 50, thereby achieving leak prevention.

[0056] In some embodiments, a plurality of liquid-blocking plates 42 are provided in the reverse channel, and the plurality of liquid-blocking plates 42 are staggered and arranged on the inner walls on both sides of the reverse channel. When liquid passes through the reverse channel, the liquid-blocking plates 42 form an obstacle to the liquid flow, reduce the kinetic energy of the liquid flow, and thus reduce the liquid flow velocity.

[0057] In some embodiments, the liquid blocking plate 42 is inclinedly disposed on the inner wall of the reverse channel, and the inclination direction of the liquid blocking plate 42 is opposite to the flow direction of the liquid. When the liquid approaches and bypasses the liquid blocking plate 42, the liquid flow lines turn inward towards the interior of the liquid blocking plate 42, the pressure of the liquid flow decreases, and the liquid flow velocity decreases.

[0058] In some embodiments, the liquid-blocking plate 42 forms an acute angle with the inner wall of the reverse channel, and the opening direction of this acute angle is opposite to the liquid flow direction. Specifically, the angle is no greater than 90°. When liquid passes through the liquid-blocking plate 42, the liquid first flows towards the angle, guiding the liquid to flow along a specific path, avoiding direct impact, forming a low-speed zone, and slowing down the liquid flow rate.

[0059] It should be noted that, along the direction of liquid flow, the height of the plurality of liquid blocking plates 42 decreases sequentially to prevent liquid from rushing in directly and reducing the leak-proof effect.

[0060] In some embodiments, such as Figure 10As shown, the liquid blocking plate 42 includes a first liquid blocking plate 421 and a second liquid blocking plate 422. The first liquid blocking plate 421 is disposed on the inner wall of the first side of the reverse groove, and the second liquid blocking plate 422 is disposed on the inner wall of the second side of the reverse groove. The first liquid blocking plate 421 and the second liquid blocking plate 422 are staggered.

[0061] In some embodiments, the end faces of the first liquid blocking plate 421 and the second liquid blocking plate 422 that are close to each other intersect to prevent the formation of a direct channel between the first liquid blocking plate 421 and the second liquid blocking plate 422, thereby reducing the leak-proof effect.

[0062] In some embodiments, the heights of the first liquid blocking plate 421 and the second liquid blocking plate 422 decrease sequentially in the liquid flow direction, and the liquid can only pass through the flow channel formed by the alternating first liquid blocking plate 421 and the second liquid blocking plate 422, so as to prevent the liquid from forming backflow or eddy currents to enhance the flow velocity in the first liquid blocking plate 421 and the second liquid blocking plate 422.

[0063] In some embodiments, such as Figure 4 As shown, the atomizing core 50 includes an atomizing tube 51, a heating element 52, and a liquid guide 53. The atomizing tube 51 is installed inside the housing 10 and passes through the first liquid chamber 30 and the second liquid chamber 40. The liquid guide 53 and the heating element 52 are both installed inside the atomizing tube 51, and the liquid guide 53 encloses the heating element 52.

[0064] In some embodiments, such as Figure 8 As shown, both the atomizing tube 51 and the liquid guide 53 are provided with at least two layers. The atomizing tube 51 includes a first atomizing tube 511 and a second atomizing tube 512. The liquid guide 53 includes a first liquid guide 531 and a second liquid guide 532. The first atomizing tube 511 is at least partially disposed in the first liquid tank 30 and communicates with the first liquid tank 30. The first liquid guide 531 is disposed in the first atomizing tube 511. The second atomizing tube 512 is embedded in the first liquid guide 531 at one end away from the first atomizing tube 511. The second liquid guide 532 is attached to the second atomizing tube 512. The heating element 52 is attached to the second liquid guide 532.

[0065] In one specific embodiment, the first liquid guide 531 is in close contact with the inner wall of the first atomizing tube 511, and the first liquid guide 531 and the second liquid guide 532 are separated by the second atomizing tube 512. The liquid in the first liquid guide 531 is guided into the second liquid guide 532 through the through-hole structure in the second atomizing tube 512, reducing the speed at which the liquid flows to the second liquid guide. In addition, at the beginning of the suction, the liquid in the first liquid guide 531 can be quickly guided into the second liquid guide 532 to provide the atomization matrix for the heating element 52 and prevent dry burning at the start of suction.

[0066] It should be noted that the first liquid conductor 531 has a higher liquid absorption and retention capacity than the second liquid conductor 532, meaning the first liquid conductor 531 has a higher liquid storage capacity. Liquid flowing out of the first liquid chamber 30 is first stored in the first liquid conductor 531, and then adsorbed onto the heating element 52 via the second liquid conductor 532. By having the first liquid conductor 531 absorb the liquid, excessive liquid adsorption onto the heating element 52 can be avoided, further reducing the possibility of leakage from the heating element 52.

[0067] In some embodiments, the first atomizing tube 511 is provided with a liquid inlet area, the liquid inlet 510 is provided in the liquid inlet area, the first liquid chamber 30 corresponds to the liquid inlet area of ​​the atomizing tube 51, and the first liquid chamber 30 surrounds and communicates with the liquid inlet area, and the liquid in the first liquid chamber 30 is introduced into the atomizing core 50 through the liquid inlet area.

[0068] It should be noted that, as Figure 7 As shown, the liquid inlet area is provided with multiple liquid inlets 510. When the liquid in the first liquid chamber 30 passes through the liquid inlet 510, it is resisted by the hole wall, which causes the kinetic energy of the liquid molecules to decrease but the static energy to remain unchanged. Therefore, the speed at which the liquid molecules flow to the atomizing core 50 is slowed down, thereby controlling the flow rate of the liquid in the first liquid chamber 30 into the heating element 52.

[0069] In one specific embodiment, the atomizing device has three operating positions based on the relative position of the operating part in the housing, and the working process is as follows: Power off position: When the user moves the toggle switch to the first position outwards from the housing, the first section of the moving part is fully inserted into the outlet of the first liquid tank (e.g., Figure 6 This design completely seals off the liquid channel between the first and second liquid chambers, isolating them from each other and preventing the atomizing matrix in the second chamber from flowing to the atomizing core. Simultaneously, the second section of the moving part completely blocks both the first and second air passages, preventing external air from entering and eliminating airflow within the atomizing core. This prevents the atomizing device from drawing in air, eliminating the risk of dry burning when the atomizing core is idle. This configuration is suitable for long-distance transportation and long-term storage, completely resolving leakage and core clogging issues.

[0070] Low power setting: Push the toggle switch to the second position, and the first stage will completely draw out the liquid outlet (e.g., Figure 4 The liquid channel between the first and second liquid chambers is fully open, and the liquid in the first liquid chamber continuously supplies the liquid atomizing matrix to the atomizing core through the second liquid chamber. The second section of the moving part's air inlet is laterally aligned with the air inlet end of the first air passage. The second air passage is still blocked by the second section's solid structure, and only the small-diameter first air passage is allowed to enter. The air intake of the first air passage is small, which matches the low-power output of the equipment. The aerosol gas has a moderate taste and temperature, and there is no overheating or core clogging.

[0071] High power, large air intake setting: Continue pushing the toggle switch inward to the third position, keeping the first stage disconnected from the liquid outlet (e.g. Figure 2 The end face of the first section is flush with the bottom surface of the second liquid tank. The liquid passage between the first liquid tank and the second liquid tank is continuously connected. The moving part slides to the position of the second air passage, and the air inlet connects to the second air passage. The first air passage is blocked by the second section, and only the large-diameter second air passage is used for air intake. The air intake flow rate is greatly increased. When matched with high-power heating equipment, more aerosol gas can be provided, and the aerosol taste is stronger.

[0072] The above embodiments are merely preferred implementations of the present invention. Those skilled in the art can make simple modifications or substitutions to the cross-sectional shape of the air passage, the sliding direction of the toggle switch, the arrangement of the first and second liquid tanks, and the material of the sealing element without departing from the core concept of the present invention, and all such modifications and substitutions are within the protection scope of the present invention.

[0073] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
