Description

Dual heating module atomization device and electronic cigarette

[0001] The present invention claims priority to Chinese application No. 202311219380.3, entitled “Dual heating module atomization device and electronic cigarette” filed on September 20, 2023, Chinese application No. 202323086290.X, entitled “Atomizer and atomization device” filed on November 15, 2023, and Chinese application No. 202323278474.6, entitled “Atomization device and aerosol generating device” filed on December 1, 2023, which are incorporated herein by reference. Technical Field

[0002] The present invention relates to the field of atomization technology, and in particular to a dual-heating module atomization device and an electronic cigarette. Background Art

[0003] Existing e-cigarettes typically use a single heating element and corresponding air channels to heat and atomize the e-liquid, resulting in a monotonous flavor, low vapor volume, and a poor user experience. To increase vapor volume, some e-cigarettes use two identical heating elements to simultaneously heat and atomize the e-liquid, but this still leaves the flavor monotonous and reduces the number of puffs. Therefore, it fails to meet users' demands for more puffs, a good flavor, and a diverse experience. Summary of the Invention

[0044] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0045] 1 and 2 , the electronic cigarette of the present invention includes an atomizing device and a power supply device 200 connected to each other; the power supply device 200 supplies power to the atomizing device and controls the opening and closing of the atomizing device. The atomizing device is used to heat atomizing liquid such as tobacco oil to form an aerosol.

[0046] In the present invention, the atomizer device is a dual-heating module atomizer device 100 having two sets of heating modules. The two sets of heating modules are of different types, so the aerosol formed by atomization has different tastes, making the taste of the electronic cigarette diverse, thereby improving the user's taste and experience.

[0047] As shown in FIG. 1 to FIG. 3 , in some embodiments, the dual-heating module atomization device 100 may include a first shell 10 , an end cover 20 , a base 30 , a first heating module 40 of different types, and a second heating module 50 .

[0048] The first housing 10 is a cylindrical structure, such as a circular, elliptical, flat, or polygonal cylinder. The first housing 10 has opposing first and second ends. The end cap 20 fits over the first end of the first housing 10 to close the first end, and the base 30 fits over the second end of the first housing 10 to close the second end. The first heating module 40 and the second heating module 50 are disposed within the first housing 10.

[0049] Specifically, a first air guide channel 110 , a second air guide channel 120 and a liquid storage tank 130 are provided in the first housing 10 .

[0050] The first air-guiding channel 110 and the second air-guiding channel 120 are spaced apart from each other, or in other words, arranged in parallel, within the first housing 10. The first air-guiding channel 110 and the second air-guiding channel 120 each extend along the length of the first housing 10, such that the first air-guiding channel 110 and the second air-guiding channel 120 can both be connected between the end cap 20 and the base 30. Alternatively, the first air-guiding channel 110 and the second air-guiding channel 120 can each be formed by an air-guiding tube disposed within the first housing 10.

[0051] The liquid reservoir 130 is formed between the inner wall of the first housing 10 and the outer sides of the first and second air-guiding channels 110 and 120. That is, the liquid reservoir 130 surrounds the outer sides of the first and second air-guiding channels 110 and 120. The liquid reservoir 130 can directly store atomized liquid such as e-liquid, or it can be filled with liquid-storage cotton 140 to absorb the atomized liquid.

[0052] 4 and 5 , the cross-sectional profile of the first housing 10 has a major axis x and a minor axis y. The first air-guiding channel 110 and the second air-guiding channel 120 are distributed along the major axis x and on either side of the intersection of the major axis x and the minor axis y, where 4y>x>2y; and / or the cross-sectional profile of the first housing 10 is elliptical. This structural arrangement is intended to ensure that the first air-guiding channel 110 and the second air-guiding channel 120 are relatively evenly and reasonably distributed across the cross-sectional profile of the first housing 10. This reasonable distribution of the first air-guiding channel 110 and the second air-guiding channel 120 allows for the rational utilization of the atomized liquid, such as e-liquid, stored in the liquid reservoir 130 within the first housing 10. It is understandable that the transfer of atomized liquid takes time. If the first air-guiding channel 110 and the second air-guiding channel 120 are located close together in a corner, the atomized liquid near them may be quickly depleted, or even dry-burn, while the atomized liquid further away from the first air-guiding channel 110 and the second air-guiding channel 120 remains unused.

[0053] Further preferably, the first air guiding channel 110 and the second air guiding channel 120 are symmetrical about the minor axis y on the major axis x. The ratio of the distance between the first air guiding channel 110 and the second air guiding channel 120 to the length of the major axis x is in the range of 0.5-0.8.

[0054] The dual-heating module atomizer 100 may, as needed, include liquid storage cotton 140 filled in the liquid storage tank 130. Referring to FIG4 , when the liquid storage tank 130 is filled with liquid storage cotton 140, a pressure relief groove 11 may be provided between at least one side of the liquid storage cotton 140 and the inner wall surface of the first housing 10. This provides a better sealing effect, allows air to enter the first housing 10 more smoothly and without whistling, and reduces the risk of oil leakage.

[0055] Corresponding to the first air guiding channel 110 and the second air guiding channel 120 , the end cover 20 is provided with a first smoke outlet 21 and a second smoke outlet 22 spaced apart from each other. The first smoke outlet 21 is connected to the first air guiding channel 110 , and the second smoke outlet 22 is connected to the second air guiding channel 120 .

[0056] It can be understood that the end cover 20 can be integrally formed on the first end of the first shell 10, or assembled on the first end of the first shell 10 by means of tight fit or the like.

[0057] The base 30, facing away from the end cap 20, fits onto the second end of the first housing 10, closing the second end of the first housing 10 while also supporting the first and second air channels 110, 120. The base 30 is preferably made of a flexible, elastic material such as silicone. The base 30 fits snugly onto the port at the second end of the first housing 10, with the outer circumference of the base 30 sealingly engaging the inner circumference of the port at the second end.

[0058] A first positioning post 31 and a second positioning post 32 are further provided on the side of the base 30 facing the interior of the first housing 10. The first positioning post 31 can be inserted into the first air duct 110 and fixed relative to the first air duct 110; the second positioning post 32 can be inserted into the second air duct 120 and fixed relative to the second air duct 120. Furthermore, each of the first positioning post 31 and the second positioning post 32 has a channel hole extending through the outer surface of the base 30 facing away from the first housing 10. The first air duct 110 and the second air duct 120 are ventilated to the exterior of the first housing 10 through their corresponding channel holes.

[0059] The first heating module 40 is vertically disposed within the first air guide channel 110, and atomized liquid from the liquid reservoir 130 flows to the first heating module 40 for atomization. The atomized liquid in the liquid reservoir 130 is adsorbed onto the first heating module 40. When powered on and heated, the first heating module 40 heats the atomized liquid and atomizes it into an aerosol. The aerosol then flows along the first air guide channel 110 toward the end cap 20 and is discharged through the first smoke outlet 21.

[0060] In the present invention, in combination with Figures 2 and 6, the first heating module 40 includes a first liquid guide member 41 and at least one heating net 42; the first liquid guide member 41 may be a cylindrical structure, provided with a central through hole 411 running through its opposite ends, and the heating net 42 is arranged in the central through hole 411. In the central through hole 411 of the first liquid guide member 41, the heating net 42 may be attached to the inner wall surface of the central through hole 411, or may be partially embedded in the inner wall surface of the central through hole 411. When there are two or more heating nets 42, the heating nets 42 are arranged at intervals along the length direction of the central through hole 411, and the heating nets 42 may be relatively independent, with their respective conductive pins extending outward to connect to the power supply device, or the heating nets 42 may share conductive pins, with the shared conductive pins extending outward to connect to the power supply device.

[0061] In the first air guide channel 110, the first liquid guide member 41 is arranged vertically, so that the length direction of the central through hole 411 on the first liquid guide member 41 is parallel to the length direction of the first air guide channel 110, and the central through hole 411 is connected to the first air guide channel 110, and even the central axes of the two overlap. The end of the first liquid guide member 41 facing the base 30 can abut against the first positioning column 31 of the base 30, and be fixed in the first air guide channel 110 through the support of the first positioning column 31. The conductive pins of the heating network 42 can extend along the central through hole 411 of the first liquid guide member 41 and the channel hole of the first positioning column 31 to the outside of the first shell 10, or extend along the central through hole 411 of the first liquid guide member 41 into the channel hole of the first positioning column 31.

[0062] In order to realize the liquid-conducting connection between the first heating module 40 and the liquid storage tank 130, at least one first liquid-conducting hole 111 is opened on the first air-conducting channel 110 corresponding to the position of the first liquid-conducting component 41. The first liquid-conducting hole 111 connects the first liquid-conducting component 41 and the liquid storage tank 130, so that the atomized liquid in the liquid storage tank 130 (or the atomized liquid adsorbed by the liquid storage cotton 140 in the liquid storage tank 130) can be adsorbed by the first liquid-conducting component 41.

[0063] The first liquid-conducting member 41 can be a liquid-conducting cotton made of cotton material, or a porous ceramic liquid-conducting member made of ceramic material.

[0064] 2 and 7 , in one embodiment, the second heating module 50 is disposed transversely within the second air-guiding channel 120 and is connected to the liquid storage tank 130. Atomized liquid within the liquid storage tank 130 is adsorbed onto the second heating module 50. When the second heating module 50 is powered on and heated, the atomized liquid is heated and atomized into an aerosol. The aerosol flows along the second air-guiding channel 120 toward the end cap 20 and is output from the second smoke outlet 22.

[0065] The second heating module 50 is different from the first heating module 40 . The second heating module 50 includes a second liquid guiding member 51 and a spiral heating wire 52 sleeved on the second liquid guiding member 51 . The second liquid guiding member 51 may be, but is not limited to, liquid guiding cotton.

[0066] The second liquid-guiding member 51 is disposed transversely within the second air-guiding channel 120. At least one end of the second liquid-guiding member 51 passes through the second air-guiding channel 120 into the liquid storage tank 130. Atomized liquid within the liquid storage tank 130 can be adsorbed onto the second liquid-guiding member 51. Specifically, a second liquid-guiding hole 121 communicating with the liquid storage tank 130 is provided on the second air-guiding channel 120 at a location corresponding to one or both ends of the second liquid-guiding member 51. One or both ends of the second liquid-guiding member 51 can pass through the second liquid-guiding hole 121, thereby allowing the atomized liquid within the liquid storage tank 130 (or the atomized liquid adsorbed by the liquid-storage cotton 140 within the liquid storage tank 130) to be adsorbed by the second liquid-guiding member 51.

[0067] The conductive pin of the heating wire 52 can extend to the outside of the first shell 10 along the second air guide channel 120 and the channel hole of the second positioning column 32, or extend into the channel hole of the second positioning column 32 along the second air guide channel 120, or along the second air guide channel 120 and through the wiring through hole set on the base 30. The wiring through hole can be set on the outside of the second positioning column 32.

[0068] As shown in FIG8 , in another embodiment, the second heating module 50 is vertically disposed in the second air guide channel 120 and is connected to the liquid storage tank 130 for liquid conduction. Unlike FIG7 , the second heating module 50 of this embodiment is a double-wire parallel-wound heating module, which may specifically include a double-wire parallel-wound heating wire 501 and a second liquid guide member 502 wrapped around the outside of the heating wire 501. The second liquid guide member 502 may be a cylindrical structure, vertically disposed in the second air guide channel 120. The second liquid guide hole 121 on the second air guide channel 120 connects the second liquid guide member 502 with the liquid storage tank 130, so that the atomized liquid in the liquid storage tank 130 (or the atomized liquid adsorbed by the liquid storage cotton 140 in the liquid storage tank 130) can be adsorbed by the second liquid guide member 502.

[0069] The second liquid-conducting member 502 may be a liquid-conducting cotton made of cotton material, or may be formed by winding non-woven fabric, or may be a porous ceramic liquid-conducting member made of ceramic material.

[0070] Furthermore, as shown in FIG. 1 and FIG. 2 , the dual-heating module atomizing device 100 of the present invention may also selectively include a mouthpiece 60 , a first switch 71 and a second switch 72 .

[0071] The mouthpiece 60 is mounted on the end cap 20. A mouthpiece opening 61 is provided on the mouthpiece 60, which communicates with the first and second smoke outlets 21, 22, respectively, on the end cap 20. In some embodiments, the first and second smoke outlets 21, 22 are centrally symmetrically arranged on the end cap 20. The mouthpiece opening 61 is offset from the mouthpiece 60, i.e., located to one side (not at the center) of the mouthpiece 61. This allows the mouthpiece 61 to be rotated on the end cap 20 to adjust its position so that it faces the first or second smoke outlet 21, 22.

[0072] A liquid-absorbing sponge 62 can also be provided between the mouthpiece 60 and the end cap 20 to absorb condensed liquid, preventing it from being sucked out by the user and affecting the user experience. The liquid-absorbing sponge 62 has two through-holes: one connecting the first smoke outlet 21 and the first air duct 110, and the other connecting the second smoke outlet 22 and the second air duct 120.

[0073] To achieve the rotation of the mouthpiece 60 on the end cap 20, in one embodiment, the mouthpiece 60 is detachably mounted on the end cap 20. When the mouthpiece opening 61 is selected to be aligned with the first smoke outlet 21 or aligned with the second smoke outlet 22, the mouthpiece 60 can be removed, rotated 180°, and then reattached to the end cap 20. In another embodiment, the mouthpiece 60 can rotate around the outer circumference of the end cap 20. In this way, when the mouthpiece opening 61 is selected to be aligned with the first smoke outlet 21 or aligned with the second smoke outlet 22, the mouthpiece 60 does not need to be removed and can be simply rotated 180°.

[0074] When the mouthpiece 60 is connected to the first smoke outlet 21, the mouthpiece 60, the first smoke outlet 21, and the first air guide channel 110 are connected in sequence to form an atomization channel. When the atomizer is in use, the first heating module 40 in the first air guide channel 110 is powered on to generate heat, atomizing the atomized liquid into an aerosol that is then inhaled by the user. When the mouthpiece 60 is connected to the second smoke outlet 22, the mouthpiece 60, the second smoke outlet 22, and the second air guide channel 120 are connected in sequence to form another atomization channel. When the atomizer is in use, the second heating module 50 in the second air guide channel 120 is powered on to generate heat, atomizing the atomized liquid into an aerosol that is then inhaled by the user.

[0075] The two aforementioned connection states can be alternated, or one can be selected based on user needs. When the mouthpiece 60 is connected to the first smoke outlet 21, the first heating module 40 is powered on to generate heat and atomize the atomized liquid. At this time, the mouthpiece 60 is disconnected from the second smoke outlet 22, and the second heating module 50 is not powered, and vice versa.

[0076] The first heating module 40 and the second heating module 50 can operate interchangeably. Furthermore, in one embodiment, the first heating module 40 and the second heating module 50 share a common liquid reservoir 130. When the liquid reservoir 130 is filled with liquid-storing sponges 140, the first heating module 40 and the second heating module 50 are connected to the same liquid-storing sponge 140 for liquid conduction. Even if only one heating module (the first heating module 40 or the second heating module 50) is operating to consume atomized liquid from its peripheral liquid-storing sponge 140, the capillary force of the oil-storing sponge 140 causes atomized liquid, such as tobacco oil, to naturally flow from areas with low capillary force to areas with high capillary force. This means that atomized tobacco oil is quickly replenished. In other words, atomized liquid in other areas of the liquid-storing sponge 140 is replenished to the consumption area, ensuring full utilization of the liquid-storing sponge 140, improving the utilization rate of the atomized liquid, and avoiding waste of atomized liquid due to its inability to be absorbed and heated.

[0077] In another embodiment, the liquid storage tank 130 may include a first liquid storage tank and a second liquid storage tank separated from each other; the first liquid storage tank supplies liquid to the first heating module, and the second liquid storage tank supplies liquid to the second heating module. When the liquid storage tank 130 is filled with liquid storage cotton, the liquid storage cotton also correspondingly includes a first liquid storage cotton and a second liquid storage cotton. The first liquid storage cotton is filled in the first liquid storage tank, and the second liquid storage cotton is filled in the second liquid storage tank. The first liquid storage tank and the second liquid storage tank can store the same atomized liquid, or different atomized liquids. For different atomized liquids, they are heated and atomized by the first heating module 40 and the second heating module 50 respectively to form aerosols with different smells, which can meet the user's needs to experience a variety of smells and enhance the experience.

[0078] Comparing the performance of the first heating module 40 and the second heating module 50: The first heating module 40 offers a better flavor than the second heating module 50; the second heating module 50's TPM value (measured in milligrams per puff of the e-cigarette, representing the volume of smoke per puff) is lower than that of the first heating module 40. Given the same amount of atomized liquid, the second heating module 50 delivers more puffs than the first heating module 40. Due to the different performance characteristics of the first and second heating modules 40, 50, a single atomizer or e-cigarette can offer at least two flavors and experiences, achieving a diverse taste and experience. Users can choose the flavor and experience that best suits their preferences and needs.

[0079] The first switch 71 is provided in correspondence with the first heating module 40 and controls the power on and off of the first heating module 40 via the power supply device 200. The second switch 72 is provided in correspondence with the second heating module 50 and controls the power on and off of the second heating module 50 via the power supply device 200. The first switch 71 and the second switch 72 can be positioned on the surface of the base 30 facing away from the first housing 10, or can be positioned on the power supply device 200.

[0080] Preferably, the first switch 71 is a pneumatic switch (microphone), and the second switch 72 is a pneumatic switch (microphone). When the user selects the first heating module 40, the user draws, and the atomization channel formed by the connection between the mouthpiece 60, the first smoke outlet 21, and the first air guide channel 110 generates negative pressure. The first switch 71 responds, and the power supply device 200 controls the first heating module 40 to be powered. Similarly, when the user selects the second heating module 50, the user draws, and the atomization channel formed by the connection between the mouthpiece 60, the second smoke outlet 22, and the second air guide channel 120 generates negative pressure. The second switch 72 responds, and the power supply device controls the first heating module 40 to be powered.

[0081] It is understood that the first switch 71 and the second switch 72 may each be a mechanical switch such as, but not limited to, a push button switch, and the mechanical switch is electrically connected to the power supply. When the first switch 71 is activated, the first switch 71 controls the power supply to energize the first heating module 40; when the second switch 72 is activated, the first switch 71 controls the power supply to energize the second heating module 50.

[0082] 2 , the power supply device 200 is connected to one end of the dual-heating module atomization device 100 having the base 30 . The power supply device 200 may further include a second housing 210 , a battery cell 220 installed in the second housing 210 , and a control assembly 230 .

[0083] The control component 230 is electrically connected to the battery cell 220 and the dual heating module atomization device 100 respectively, and a signal connection is formed at the same time. The battery cell 220 supplies power to the first heating module 40 and the second heating module 50 through the control component 230. After the first switch 71 and the second switch 72 respond under negative pressure, they output a signal to the control component 230. The control component 230 controls the battery cell 220 to supply power to the corresponding heating module (the first heating module 40 or the second heating module 50) according to the received signal.

[0084] The second shell 210 is used to mate with the first shell 10, forming the entire outer shell of the electronic cigarette. Alternatively, the second shell 210 extends and covers the outside of the first shell 10, with the second shell 210 serving as the outer shell of the electronic cigarette. The outer structure of the second shell 210 determines the outer structure of the electronic cigarette. Alternatively, the electronic cigarette further includes a shell 240, which is sleeved outside the first shell 10 and the second shell 210. The outer structure of the shell 240 determines the outer structure of the electronic cigarette, also improving the overall appearance of the electronic cigarette.

[0085] 2 and 3 , the second shell 210 extends and covers the outside of the first shell 10 . The second shell 210 also covers the end cover 20 inside. A positioning recess 211 may be provided at the end of the second shell 210 corresponding to the outside of the end cover 20 . The mouthpiece 60 is at least partially embedded in the positioning recess 211 . The inner circumferential surface of the positioning recess 211 abuts against part of the outer circumferential side surface of the mouthpiece 60 , thereby limiting the radial movement of the mouthpiece 60 on the second shell 210 .

[0086] Corresponding to the first smoke outlet 21 and the second smoke outlet 22 on the end cap 20, the bottom surface of the positioning recess 211 is also provided with a first opening 212 that is directly connected to the first smoke outlet 21, and a second opening 213 that is directly connected to the second smoke outlet 22. The mouthpiece 61 on the cigarette holder 60 can be connected to the first smoke outlet 21 through the first opening 212, or connected to the second smoke outlet 22 through the second opening 213. The cooperation between the positioning recess 211 on the second housing 210 and the cigarette holder 60 can improve the connection reliability of the cigarette holder 60 in the atomizer device and prevent the mouthpiece 61 of the cigarette holder 60 from being misaligned with the smoke outlet 21 or the second smoke outlet 22 to which it is currently connected.

[0087] When the mouthpiece 60 is separated from the second shell 210, the positioning recess 211 and the first opening 212 and the second opening 213 on its bottom surface are exposed, and the positions of the first opening 212 and the second opening 213 can be identified, which is convenient for connecting the mouthpiece mouth 61 of the mouthpiece 60 with the first opening 212 or the second opening 213 as needed, thereby achieving the purpose of connecting with the first smoke outlet 21 or the second smoke outlet 22.

[0088] As shown in FIG3 , the mouthpiece 60 may further comprise a mouthpiece body 63, a positioning protrusion 64 connected to one side of the mouthpiece body 63, and a smoke outlet pipe 65 connected to the opposite side of the mouthpiece body 63. The passage within the smoke outlet pipe 65 extends through the mouthpiece body 63 and the positioning protrusion 64 to form a mouthpiece opening 61. The mouthpiece 60 is fitted into the positioning recess 211 with the positioning protrusion 64, and the outer periphery of the mouthpiece body 63 can be flush with the outer periphery of the second housing 210.

[0089] The diameter of the mouthpiece opening 61 is larger than that of the first opening 212. This arrangement facilitates communication between the mouthpiece opening 61 and the first opening 212. It is understandable that due to manufacturing precision, component dimensions may not be as precise as expected, and during use, the mouthpiece opening 61 may not completely align with the center of the first opening 212. However, by making the mouthpiece opening 61 larger than the diameter of the first opening 212, even if the mouthpiece opening 61 of the cigarette holder 60 does not completely align with the center of the first opening 212, the mouthpiece opening 61 can still cover the entire first opening 212 and fully receive all aerosol from the first heating module 40 without affecting the aerosol transmission speed. Furthermore, the manufacturing precision requirements for related components are reduced, thereby reducing manufacturing difficulty, lowering manufacturing costs, and improving product yield.

[0090] Similarly, the diameter of the mouthpiece 61 is larger than the diameter of the second opening 213, so that even if the mouthpiece 61 of the mouthpiece 60 is not completely aligned with the center of the second opening 213, the mouthpiece 61 can still cover the entire second opening 213 and can still fully receive all the aerosol from the second heating module 50 without affecting the transmission speed of the aerosol. It also reduces the manufacturing precision requirements of related components, which is conducive to reducing manufacturing difficulty, reducing manufacturing costs and improving yield rate.

[0091] A vent hole 214 is provided on the sidewall of the second housing 210, communicating with the interior of the second housing 210. An airflow channel is formed within the second housing 210, connecting the vent hole 214 to the first switch 71 and the second switch 72 of the dual-heating module atomizer 100. When a user inhales through the mouthpiece 60 of the electronic cigarette, external air enters the interior of the second housing 210 through the vent hole 214, triggering the first switch 71 or the second switch 72.

[0092] The second housing 210 is further provided with a charging interface 250 electrically connected to the control assembly 230 , so that the battery cell 220 is charged by connecting to the mains power through the charging interface 250 .

[0093] When using the electronic cigarette of the above embodiment of the present invention, the user aligns the mouthpiece 61 of the mouthpiece 60 with the first smoke outlet 21 or the second smoke outlet 22 according to their desired taste, thereby connecting the mouthpiece 61 to the first heating module 40 or the second heating module 50. When the user draws on the mouthpiece 61, external air enters the electronic cigarette, triggering the first switch 71 or the second switch 72, which powers on and heats the corresponding first heating module 40 or second heating module 50, thereby heating and atomizing the atomized liquid, forming an aerosol that is inhaled by the user.

[0094] When the user wants to change the taste, he only needs to rotate the mouthpiece 60 and change the position of the mouthpiece opening 61 so that the mouthpiece opening 61 is connected to the heating module (the second heating module 50 or the first heating module 40). When inhaling, the corresponding heating module can be triggered to work and produce aerosols with different tastes.

[0095] As shown in FIG9 , another embodiment of a dual-heating module atomizer 100 includes a first housing 10, an end cap 20, a base 30, a mouthpiece 60, and different types of first heating modules 40 and second heating modules 50. The assembly and specific configuration of the first housing 10, end cap 20, base 30, mouthpiece 60, first heating module 40, and second heating module 50 can all be referred to the embodiments corresponding to FIG2 to FIG8 above, and will not be repeated here.

[0096] The mouthpiece 60 fits over the end cap 20. It is provided with a mouthpiece opening 61, which connects to the first and second smoke outlets 21, 22 on the end cap 20, respectively. Unlike the embodiments described in Figures 2 to 8 , in this embodiment, the mouthpiece opening 61 on the mouthpiece 60 is centrally located, enabling simultaneous communication with the first and second smoke outlets 21, 22 on the end cap 20. This allows for simultaneous communication with the first and second air ducts 110, 120 within the first housing 10. To enhance the flavor, the user can activate the first heating module 40 and the second heating module 50 simultaneously.

[0097] The mouthpiece 60 may specifically include a cylindrical structure 610. The cylindrical structure 610 defines a first air passage 611 for the user to inhale. The first air passage 611 extends along the height direction of the atomizing device to pass through opposite ends of the cylindrical structure 610 to form a mouthpiece opening 61.

[0098] The inner diameter of the cylindrical structure 610 gradually decreases from the side close to the end cap 20 to the side away from the end cap 20, and the wall of the cylindrical structure 610 forms a curved transition. This can guide the aerosol, thereby preventing the formation of vortexes in the smoke in the first airway 611 and the formation of liquid or water accumulation.

[0099] The first heating module 40 and the second heating module 50 are powered on or off by turning on and off the first switch 71 and the second switch 72 respectively.

[0100] Specifically, in conjunction with Figures 1 and 9, the dual heating module atomization device 100 further includes a microphone sensor switch (i.e., a pneumatic switch) 70, which is used to control the connection or disconnection of the first heating module 40 and the second heating module 50 with the power supply device 200.

[0101] The microphone sensor switch 70 responds to the negative pressure generated within the first airway 611, first air channel 110, and second air channel 120 when a user draws on the mouthpiece 60. When the user draws on the mouthpiece 60, the capacitor plates within the microphone sensor switch 70 deform, causing the capacitance of the switch 70 to change. When the capacitance of the switch 70 reaches a set threshold, the switch 70 switches from an off state to an on state. At this point, the power supply device 200 supplies power to the first heating module 40 and the second heating module 50.

[0102] The power supply device 200 is connected to one end of the dual-heating module atomization device 100 having the base 30. The power supply device 200 may further include a second housing 210, a battery cell 220 installed in the second housing 210, and a control component 230.

[0103] The control component 230 is electrically connected to the battery cell 220 and the dual heating module atomization device 100 respectively, and forms a signal connection at the same time. The battery cell 220 supplies power to the first heating module 40 and the second heating module 50 through the control component 230. After the microphone sensor switch 70 responds under negative pressure, it outputs a signal to the control component 230. The control component 230 controls the battery cell 220 to supply power to the first heating module 40 or the second heating module 50 according to the received signal.

[0104] The second shell 210 is used to mate with the first shell 10, forming the entire outer shell of the electronic cigarette. Alternatively, the second shell 210 extends and covers the outside of the first shell 10, with the second shell 210 serving as the outer shell of the electronic cigarette. The outer structure of the second shell 210 determines the outer structure of the electronic cigarette. Alternatively, the electronic cigarette further includes a shell 240, which is sleeved outside the first shell 10 and the second shell 210. The outer structure of the shell 240 determines the outer structure of the electronic cigarette, also improving the overall appearance of the electronic cigarette.

[0105] Regarding the second shell 210 extending and covering the outside of the first shell 10, the mouthpiece 60 is connected to the end of the second shell 210. The mouthpiece 60 can be integrally formed with the second shell 210, or can be independently provided and connected as one.

[0106] The configuration of the vent holes, charging port, etc. on the power supply device 200 can refer to the embodiment shown in FIG2 above, and will not be described in detail here.

[0107] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention's description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
