Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to a vapor generation device. Background Technology

[0002] A vapor generator is an electronic device that can atomize vapor-forming substances such as e-liquid and medicinal liquid stored in it into vapor through electric heating. A vapor generator typically includes an atomizing core and a liquid storage chamber for storing vapor-forming substances. The atomizing core draws vapor-forming substances from the liquid storage chamber and heats and atomizes the drawn vapor-forming substances to produce vapor for the user to inhale.

[0003] However, most aerosol generators on the market are currently equipped with only one atomizing core and one liquid storage chamber. One liquid storage chamber can only store one flavor of aerosol forming substance, which means that the aerosol generator can only provide one flavor of aerosol. Therefore, there is a technical problem of limited flavor, which cannot meet users' needs for inhaling aerosols of different flavors. Utility Model Content

[0029] Compared with the prior art, the beneficial effects of this application are:

[0030] 1. In the vapor generation device provided in this application, at least two liquid storage chambers are provided, and at least two atomizing cores are provided. Different liquid storage chambers can store vapor forming substances of different flavors, and different atomizing cores can draw vapor forming substances of different flavors from different liquid storage chambers for heating and atomization, thereby generating at least two different flavors of vapor, thus meeting the user's demand for vapor inhalation of different flavors.

[0031] 2. The flavor can be switched by changing the on / off state of the switch and the position of the airway switch, which is quite convenient.

[0032] 3. During vaping, the two atomizing cores operate independently. The first atomizing core produces a vapor of one flavor, which is then transported to the mouthpiece through the first airflow channel. The second atomizing core produces a vapor of another flavor, which is transported to the mouthpiece through the second airflow channel. Because the first and second airflow channels are independent of each other, and when the air intake of one airflow channel is opened by the airway switch to connect with the outside, the air intake of the other airflow channel is closed by the airway switch to isolate it from the outside, this ensures that when the user bites down on the mouthpiece to inhale a vapor of one flavor, outside air only enters the airflow channel corresponding to the atomizing core that is currently atomizing, and does not enter the other airflow channel. This prevents the vapor output from the mouthpiece to the user's mouth from being mixed with air from both airflow channels, which would reduce the concentration of the vapor inhaled by the user and thus affect the user's vaping experience. In other words, the vapor produced by each atomizing core is transported to the mouthpiece through its respective airflow channel, which helps to improve the user's vaping experience.

[0069] Please refer to Figure 1-4 as well as Figure 7-16 One embodiment of this application provides a vapor generating device, which includes a housing 1, a nozzle 21, a liquid storage cup 3, a first atomizing core 41, a second atomizing core 42, an airflow sensor 51, an electronic control assembly 6, a switching switch 7, and an airway switch 8, wherein:

[0070] like Figure 4 and Figure 9 As shown, the interior of the housing 1 is provided with a first airflow channel 10A, a second airflow channel 10B and a sensing channel 10C that are independent of each other. The first airflow channel 10A has a first air inlet end 9101 and a first air outlet end 321, and the second airflow channel 10B has a second air inlet end 9201 and a second air outlet end 322.

[0071] like Figure 4 As shown, the suction nozzle 21 is connected to the top of the housing 1 (the material of the suction nozzle can be plastic). The inside of the suction nozzle 21 has a suction channel 210, which is connected to the first air outlet 321, the second air outlet 322, and the sensing channel 10C.

[0072] like Figure 3 As shown, the liquid storage cup 3 is installed inside the housing 1. The liquid storage cup 3 has a first liquid storage chamber 311 and a second liquid storage chamber 312 that are independent of each other. In specific applications, the first liquid storage chamber 311 can store a vapor-forming substance of one flavor (such as tobacco flavored e-liquid), and the second liquid storage chamber 312 can store a vapor-forming substance of another flavor (such as mint flavored e-liquid).

[0073] like Figure 3-4 and Figure 11As shown, the first atomizing core 41 is installed inside the housing 1 and is connected to the first liquid storage chamber 311 so that the first atomizing core 41 can draw vapor-forming material from the first liquid storage chamber 311 for heating and atomization to produce vapor that can be inhaled by the user. Moreover, the first atomizing core 41 is located on the airflow path of the first airflow channel 10A so that the vapor produced by the first atomizing core 41 can be carried away by the suction airflow formed in the first airflow channel 10A and transported to the mouthpiece 21 for the user to inhale.

[0074] like Figure 3-4 and Figure 16 As shown, the second atomizing core 42 is installed inside the housing 1 and is connected to the second liquid storage chamber 312 so that the second atomizing core 42 can draw vapor-forming material from the second liquid storage chamber 312 for heating and atomization to produce vapor that can be inhaled by the user. Moreover, the second atomizing core 42 is located on the airflow path of the second airflow channel 10B so that the vapor produced by the second atomizing core 42 can be carried away by the suction airflow formed in the second airflow channel 10B and transported to the mouthpiece 21 for the user to inhale.

[0075] like Figure 4 As shown, the airflow sensor 51 is installed inside the housing 1 and is set in the corresponding sensing channel 10C (in a specific implementation, the airflow sensor 51 may be at least partially located in the sensing channel 10C) to detect changes in airflow in the sensing channel 10C, thereby generating a suction signal to indicate that the user is in the process of suction or a stop signal to indicate that the user has stopped suction.

[0076] like Figure 3 and Figure 12 As shown, the electronic control component 6 is installed inside the housing 1 and electrically connected to the airflow sensor 51. The electronic control component 6 can be used to output electrical energy to the first atomizing core 41 or the second atomizing core 42 when it receives a suction signal sent by the airflow sensor, and to stop outputting electrical energy to the first atomizing core 41 or the second atomizing core 42 when it receives a stop signal sent by the airflow sensor.

[0077] like Figure 8 and Figure 12 As shown, the switch 7 is electrically connected to the electronic control assembly 6, the first atomizing core 41, and the second atomizing core 42 respectively. The switch 7 is used to connect or disconnect the electrical connection between the first atomizing core 41 and the electronic control assembly 6, and to connect or disconnect the electrical connection between the second atomizing core 42 and the electronic control assembly 6.

[0078] like Figure 7-9 , Figure 11 , Figure 13-14 and Figure 16As shown, the airway switch 8 is movably connected to the housing 1 and can move relative to the housing 1 to a first position and a second position, wherein, as Figure 7-9 and Figure 11 As shown, when the airway switch 8 is moved to the first position, the first air inlet 9101 is connected to the outside, and the second air inlet 9201 is closed by the airway switch 8 and isolated from the outside; Figure 13-14 and Figure 16 As shown, when the airway switch 8 is moved to the second position, the second air inlet 9201 is connected to the outside, and the first air inlet 9101 is closed by the airway switch 8 and isolated from the outside.

[0079] In this embodiment, it should be noted that, in specific implementation, the structure of the first atomizing core 41 and the second atomizing core 42 can be a cotton atomizing core with liquid-guiding cotton as the liquid-guiding medium, or a ceramic atomizing core with porous ceramic as the liquid-guiding medium. Of course, it can also be other types of atomizing core structures that are mature in the field. It can be determined according to the actual use requirements. This embodiment does not impose specific restrictions on the structure type of the first atomizing core 41 and the structure type of the second atomizing core 42. Optionally, both the first atomizing core 41 and the second atomizing core 42 are ceramic atomizing cores.

[0080] In this embodiment, it should be noted that, in specific implementation, the type of switch 7 can be a rotary switch, a button switch, a touch switch (such as a touch screen), or a toggle switch, as long as it meets the usage requirements. This embodiment does not impose specific limitations on this. It should be added that the structure and switching principle of rotary switches, button switches, touch switches, and toggle switches are well known in the art and will not be described in detail here.

[0081] In this embodiment, it should also be noted that in some optional implementations, the connection between the airway switch 8 and the housing 1 can be a rotatable connection. In this case, the structure of the airway switch 8 can be a knob or an adjusting ring with an air adjustment hole. In other optional implementations, the connection between the airway switch 8 and the housing 1 can also be a sliding connection. In this case, the structure of the airway switch 8 can be a sliding plate. As long as the usage requirements are met, it is acceptable. This embodiment does not impose specific restrictions on the connection method between the airway switch 8 and the housing 1 or the structure of the airway switch.

[0082] The operating principle of the vapor generation device provided in this embodiment is as follows:

[0083] Please refer to Figure 3-4 and Figure 7-12When a user needs to inhale the vapor produced by the first atomizing core 41, they can first operate the switch 7 to connect the electrical connection between the first atomizing core 41 and the electronic control component 6 and disconnect the electrical connection between the second atomizing core 42 and the electronic control component 6. Simultaneously, the airway switch 8 can be moved to the first position. Then, the user bites down on the mouthpiece 21 and inhales. Since the first air inlet 9101 of the first airflow channel 10A is connected to the outside at this time, outside air can enter the first airflow channel 10A through the first air inlet 9101 and form a suction airflow in the first airflow channel 10A. However, since the second air inlet 9201 of the second airflow channel 10B is closed by the airway switch 8, outside air cannot enter the second airflow channel 10B through the second air inlet 9201, and therefore cannot form a suction airflow in the second airflow channel 10B. This prevents the vapor produced by the first atomizing core 41 from being diluted by the suction airflow formed in the second airflow channel 10B when output from the mouthpiece 21, thus reducing the user's inhalation rate. Simultaneously, since the sensing channel 10C is connected to the suction channel 210 of the mouthpiece 21, some air in the sensing channel 10C will be drawn away by the user, which will cause the airflow in the sensing channel 10C to change. This will trigger the airflow sensor 51 to send a suction signal to the electronic control component 6 to indicate that the user is inhaling. When the electronic control component 6 receives the suction signal, it outputs electrical energy. Since the electronic control component 6 is in a connected state with the first atomizing core 41 and in a disconnected state with the second atomizing core 42, the first atomizing core 41 can obtain electrical energy and perform atomization, while the second atomizing core 42 cannot obtain electrical energy and will not perform atomization. When the suction airflow in the first airflow channel 10A flows through the first atomizing core 41, the suction airflow will carry away the vapor produced by the first atomizing core 41 and finally output it to the user's mouth through the mouthpiece 21, so that the user can inhale a vapor of a certain flavor produced by the first atomizing core 41.

[0084] Please refer to Figure 3-4 and Figure 12-16When a user needs to inhale the vapor produced by the second atomizing core 42, they can first operate the switch 7 to connect the electrical connection between the second atomizing core 42 and the electronic control component 6 and disconnect the electrical connection between the first atomizing core 41 and the electronic control component 6. Simultaneously, the airway switch 8 can be moved to the second position. Then, the user can bite down on the mouthpiece 21 and inhale. Since the second air inlet 9201 of the second airflow channel 10B is connected to the outside at this time, outside air can enter the second airflow channel 10B through the second air inlet 9201 and form a suction airflow in the second airflow channel 10B. However, since the first air inlet 9101 of the first airflow channel 10A is closed by the airway switch 8, outside air cannot enter the first airflow channel 10A through the first air inlet 9101, and therefore cannot form a suction airflow in the first airflow channel 10A. This prevents the vapor produced by the second atomizing core 42 from being diluted by the suction airflow formed in the first airflow channel 10A when output from the mouthpiece 21, thus reducing its effectiveness. The user can enjoy the inhaled taste. At the same time, since the sensing channel 10C is connected to the suction channel 210 of the mouthpiece 21, some air in the sensing channel 10C will also be drawn away by the user, which will cause the airflow in the sensing channel 10C to change. This will trigger the airflow sensor 51 to activate and send a suction signal to the electronic control component 6. When the electronic control component 6 receives the suction signal, it outputs electrical energy. Since the electronic control component 6 is connected to the second atomizing core 42 at this time, while the electronic control component 6 is disconnected from the first atomizing core 41, the second atomizing core 42 can obtain electrical energy and perform atomization, while the first atomizing core 41 will not perform atomization because it cannot obtain electrical energy. When the suction airflow in the second airflow channel 10B flows through the second atomizing core 42, the suction airflow will carry away the vapor produced by the second atomizing core 42 and finally output it to the user's mouth through the mouthpiece 21, so that the user can enjoy a different flavor of vapor produced by the second atomizing core 42.

[0085] As can be seen from the above analysis, the vapor generation device provided in this embodiment has at least the following technical effects:

[0086] 1. The first atomizing core 41 can draw a vapor-forming substance of one flavor from the first liquid storage chamber 311, heat and atomize it to produce vapor of one flavor. The second atomizing core 42 can draw a vapor-forming substance of another flavor from the second liquid storage chamber 312, heat and atomize it to produce vapor of another flavor. Moreover, under the coordinated action of the switching switch 7, the airway switch 8, the airflow sensor 51 and the electronic control component 6, the first atomizing core 41 and the second atomizing core 42 can perform atomization work separately, thereby providing users with two different flavors of vapor and meeting users' needs for inhaling vapor of different flavors.

[0087] 2. By changing the on / off state of the switch 7 and the position state of the airway switch 8, the flavor of the aerosol output by the mouthpiece 21 can be changed, which is quite convenient to operate.

[0088] 3. Since the first airflow channel 10A and the second airflow channel 10B are independent of each other, and when the air inlet of one airflow channel is opened by the airway switch 8 and connected to the external environment, the air inlet of the other airflow channel is closed by the airway switch 8 and isolated from the external environment, when the user bites the mouthpiece 21 to inhale a certain flavor of aerosol, the outside air will only enter the airflow channel corresponding to the atomizing core that is atomizing, and will not enter the other airflow channel. This can prevent the aerosol output from the mouthpiece 21 to the user's mouth from being mixed with the suction airflow from the two airflow channels, which would reduce the concentration of the aerosol inhaled by the user and thus affect the user's inhalation taste. That is, the aerosol produced by the corresponding atomizing core is transmitted to the mouthpiece 21 separately by the corresponding airflow channel, which is conducive to improving the user's inhalation taste.

[0089] Furthermore, in some optional embodiments of this application, the airway switch 8 may have the following structural form:

[0090] Please refer to Figure 4 , Figure 9-11 as well as Figure 14-16 The airway switch 8 includes an adjusting plate 81 slidably connected to the housing 1. The adjusting plate 81 has an air inlet 810 that maintains communication with the outside.

[0091] like Figure 4 and Figure 9-11 As shown, when the adjusting plate 81 slides to the first position, the first air inlet 9101 is connected to the air inlet 810 and the adjusting plate 81 closes the second air inlet 9201. Thus, when the user bites the suction nozzle 21 to suck, the air from the outside environment can enter the first airflow channel 10A through the air inlet 810 on the adjusting plate 81 and form a suction airflow in the first airflow channel 10A. At this time, since the second air inlet 9201 of the second airflow channel 10B is closed by the adjusting plate 81, the air from the outside environment cannot enter the second airflow channel 10B through the second air inlet 9201, and therefore cannot form a suction airflow in the second airflow channel 10B.

[0092] like Figure 4 and Figure 14-16As shown, when the adjusting plate 81 slides to the second position, the second air inlet 9201 is connected to the air inlet 810 and the adjusting plate 81 closes the first air inlet 9101. Thus, when the user bites the mouthpiece 21 to suck, the air from the outside environment can enter the second airflow channel 10B through the air inlet 810 on the adjusting plate 81 and form a suction airflow in the second airflow channel 10B. At this time, since the second air inlet 9201 of the first airflow channel 10A is closed by the adjusting plate 81, the air from the outside environment cannot enter the first airflow channel 10A through the first air inlet 9101, and therefore cannot form a suction airflow in the first airflow channel 10A.

[0093] In this embodiment, based on the above structural design, the user can selectively open the first airflow channel 10A or the second airflow channel 10B by sliding the adjustment plate 81, which is more convenient to operate.

[0094] Further, please refer to Figure 7 , Figure 9 , Figure 11 , Figure 13-14 and Figure 16 In some optional embodiments of this application, the airway switch 8 further includes a push plate 82 fixedly connected to the adjusting plate 81 (specifically, the push plate 82 can be fixedly connected to the adjusting plate 81 by snap-fit, adhesive, or other means). The push plate 82 has an exposed first operating part 821 protruding from the side facing away from the adjusting plate 81. The air inlet 810 includes a first air inlet 8101 and a second air inlet 8102 spaced apart. When the first operating part 821 is subjected to an external force (which can be a pushing force applied by the user to the first operating part 821), the adjusting plate 81 is driven to slide to the first position. When the first air intake end 9101 is connected to the first air intake port 8101 and the adjusting plate 81 closes the second air intake end 9201, the first air intake end 9101 is connected to the external environment and the second air intake end 9201 is isolated from the external environment. When the first operating part 821 is subjected to external force and drives the adjusting plate 81 to slide to the second position, the second air intake end 9201 is connected to the second air intake port 8102 and the adjusting plate 81 closes the first air intake end 9101. At this time, the second air intake end 9201 is connected to the external environment and the first air intake end 9101 is isolated from the external environment.

[0095] In this embodiment, based on the above structural design, on the one hand, by adding a push plate 82 with a second operating part 521, the user can more conveniently and effortlessly push the adjusting plate 81 to slide; on the other hand, by setting the number of air inlets 810 on the adjusting plate 81 to two (i.e., the first air inlet 8101 and the second air inlet 8102), compared to setting a single air inlet 810, it is beneficial to reduce the sliding stroke of the adjusting plate 81 when the user selectively opens the first airflow channel 10A or the second airflow channel 10B. These two aspects improve the user's operating experience.

[0096] Further, please refer to Figure 7-16 In some optional embodiments of this application, the switch 7 is a slide switch, and the electronic control component 6 includes a battery 61 and a control circuit board 62. The control circuit board 62 is electrically connected to the battery 61, the airflow sensor 51, and the switch 7, respectively. The switch 7 is connected to the regulating plate 81 and can change its switching state by following the movement of the regulating plate 81; wherein:

[0097] like Figure 7-12 As shown, when the adjustment plate 81 slides to the first position, the switch 7 connects the first atomizing core 41 to the control circuit board 62 and disconnects the second atomizing core 42 from the control circuit board 62. Thus, when the user bites the mouthpiece 21 to inhale, ambient air enters the first airflow channel 10A through the first air inlet 8101, forming a suction airflow within the channel. Simultaneously, the airflow within the sensing channel 10C changes, triggering the airflow sensor 51 to send a suction signal to the control circuit board 62. When the control circuit board 62 receives this suction signal, it... The control circuit board 62 controls the battery 61 to output electrical energy. Since the control circuit board 62 is in a connected state with the first atomizing core 41 and in a disconnected state with the second atomizing core 42, the first atomizing core 41 can obtain electrical energy through the control circuit board 62 and perform atomization, while the second atomizing core 42 cannot obtain electrical energy and will not perform atomization. When the suction airflow in the first airflow channel 10A flows through the first atomizing core 41, the suction airflow will carry away the vapor produced by the first atomizing core 41 and finally output it to the user's mouth through the mouthpiece 21, so that the user can inhale a vapor of a certain flavor produced by the first atomizing core 41.

[0098] like Figure 8 as well as Figure 12-16As shown, when the adjustment plate 81 slides to the second position, the switch 7 connects the second atomizing core 42 to the control circuit board 62 and disconnects the first atomizing core 41 from the control circuit board 62. Thus, when the user bites the mouthpiece 21 to inhale, ambient air enters the second airflow channel 10B through the second air inlet 8102, forming a suction airflow within the channel. Simultaneously, the airflow within the sensing channel 10C changes, triggering the airflow sensor 51 to send a suction signal to the control circuit board 62. When the control circuit board 62 receives this suction signal, it... The control circuit board 62 controls the battery 61 to output electrical energy. Since the control circuit board 62 is in a connected state with the second atomizing core 42 and in a disconnected state with the first atomizing core 41, the second atomizing core 42 can obtain electrical energy through the control circuit board 62 and perform atomization, while the first atomizing core 41 cannot obtain electrical energy and will not perform atomization. When the suction airflow in the second airflow channel 10B flows through the second atomizing core 42, the suction airflow will carry away the vapor produced by the second atomizing core 42 and finally output it to the user's mouth through the mouthpiece 21, so that the user can inhale a different flavor of vapor produced by the second atomizing core 42.

[0099] In this embodiment, a sliding switch is used as the switching switch 7 and connected to the adjustment plate 81. When the user pushes the adjustment plate 81 to slide, the sliding switch slides relative to the housing 1. This allows the electrical connection between the first atomizing core 41 and the control circuit board 62 to be connected simultaneously with the first airflow channel 10A (or, the electrical connection between the second atomizing core 42 and the control circuit board 62 to be connected simultaneously with the second airflow channel 10B). In other words, the opening and closing state of the airflow channel is associated with the on / off state of the atomizing core. This allows the user to select the desired flavor of aerosol by operating only the airway switch 8, without having to operate the switching switch 7 and the airway switch 8 separately. This simplifies the user's operation and improves the user experience.

[0100] Furthermore, in some optional embodiments of this application, when the switching switch 7 is a slide switch, the specific structural form of the switching switch 7 can be as follows:

[0101] Please refer to Figure 4 , Figure 8 and Figure 12The control circuit board 62 includes a microcontroller unit 621 and a switching transistor 622. The microcontroller unit 621 is electrically connected to the battery 61, the switching transistor 622, and the airflow sensor 51. The switching transistor 622 is electrically connected to the battery 61 and the switch 7. The switch 7 includes a first fixed contact S1, a second fixed contact S2, a movable contact K, and a slider 74. The first fixed contact S1 is electrically connected to the first atomizing core 41, the second fixed contact S2 is electrically connected to the second atomizing core 42, the movable contact K is connected to the slider 74 and electrically connected to the switching transistor 622, and the slider 74 is connected to the adjustment plate 81 and can move with the adjustment plate 81.

[0102] When the adjustment plate 81 slides to the first position, the slider 74 causes the movable contact K to contact the first fixed contact S1 and isolate it from the second fixed contact S2. This connects the switching tube 622 and the first atomizing core 41 and disconnects the electrical connection between the switching tube 622 and the second atomizing core 42. Thus, when the user bites the mouthpiece 21 to inhale, the airflow sensor 51 sends an inhalation signal to the microcontroller unit 621. When the microcontroller unit 621 receives this inhalation signal... The microcontroller unit 621 controls the battery 61 to output electrical energy and controls the switch tube 622 to conduct. Since the switch tube 622 is in a connected state with the first atomizing core 41 and in a disconnected state with the second atomizing core 42, when the switch tube 622 is conducted, the electrical energy output by the battery 61 can be transmitted to the first atomizing core 41 through the switch tube 622, so that the first atomizing core 41 can perform atomization work, while the second atomizing core 42 will not perform atomization work because it cannot obtain electrical energy.

[0103] When the adjustment plate 81 slides to the second position, the slider 74 causes the movable contact K to contact the second fixed contact S2 and isolate it from the first fixed contact S1. This connects the switching tube 622 and the second atomizing core 42 and disconnects the electrical connection between the switching tube 622 and the first atomizing core 41. Thus, when the user bites the mouthpiece 21 to inhale, the airflow sensor 51 sends a suction signal to the microcontroller unit 621. When the microcontroller unit 621 receives this suction signal... The microcontroller unit 621 controls the battery 61 to output electrical energy and controls the switch tube 622 to conduct. Since the switch tube 622 is in a connected state with the second atomizing core 42 and in a disconnected state with the first atomizing core 41, when the switch tube 622 is conducted, the electrical energy output by the battery 61 can be transmitted to the second atomizing core 42 through the switch tube 622, so that the second atomizing core 42 can perform atomization work, while the first atomizing core 41 will not perform atomization work because it cannot obtain electrical energy.

[0104] In this embodiment, based on the above structural design, the user can easily select the desired flavor of aerosol by simply sliding the adjustment plate 81 to the corresponding position. It should be noted that, in specific implementations, the connection between the slider 74 and the adjustment plate 81 can be a snap-fit, adhesive, or other method, as long as it meets the usage requirements. This embodiment does not impose specific limitations on this. Furthermore, in specific implementations, the switching transistor 622 can be a diode, transistor, metal-oxide-semiconductor field-effect transistor, etc., as long as it meets the usage requirements. This embodiment does not impose specific limitations on the type of switching transistor 622.

[0105] Further, please refer to Figure 3-6 In some optional embodiments of this application, the airflow sensor 51 is sealed and installed in one end of the sensing channel 10C, and one side of the airflow sensor 51 is connected to the outside and the other side is connected to the sensing channel 10C. The end of the sensing channel 10C away from the airflow sensor 51 is the airflow sensing end 10C1. The first air outlet 321, the second air outlet 322, and the airflow sensing end 10C1 are all located on the top of the liquid storage cup 3 and are spaced apart from each other. The air inlet of the suction channel 210 is spaced apart from the top of the liquid storage cup 3 and is staggered from the first air outlet 321 and the second air outlet 322. The port of the airflow sensing end 10C1 is closed and at least one vent hole 3134 is opened on the side wall of the airflow sensing end 10C1. The sensing channel 10C is connected to at least one of the first air outlet 321 and the second air outlet 322 through at least one vent hole 3134, thereby realizing the connection between the sensing channel 10C and the suction channel 210.

[0106] In this embodiment, based on the above structural design, regardless of whether the first airflow channel 10A or the second airflow channel 10B is in a conducting state, when the user bites the mouthpiece 21 to inhale, some of the air in the sensing channel 10C will be drawn away by the user, causing the air pressure on the side of the airflow sensor 51 connected to the sensing channel 10C to decrease. This creates a pressure difference between the two sides of the airflow sensor 51, triggering the airflow sensor 51 to send a suction signal to the electronic control component 6 indicating that the user is inhaling. The electronic control component 6 then outputs electrical energy to the first atomizing core 41 or the second atomizing core 42 based on this suction signal. When the user stops inhaling, the airflow in the sensing channel 10C no longer changes, so that no pressure difference is generated between the two sides of the airflow sensor 51. Consequently, the airflow sensor 51 sends a stop signal to the electronic control component 6 indicating that the user has stopped inhaling, so that the electronic control component 6 stops outputting electrical energy to the first atomizing core 41 or the second atomizing core 42 based on this stop signal.

[0107] During user suction, the vapor may condense on the inner wall of the suction channel 210 as it flows through it, producing condensate. Since the end of the sensing channel 10C furthest from the airflow sensor 51 is closed, the condensate on the inner wall of the suction channel 210 is unlikely to flow directly into the sensing channel 10C. This effectively reduces the risk of the airflow sensor 51 becoming wetted by the condensate, leading to decreased sensitivity or even damage. Furthermore, because the first outlet 321 of the first airflow channel 10A and the second outlet 322 of the second airflow channel 10B are staggered from the inlet of the suction channel 210, the condensate formed on the inner wall of the suction channel 210... The condensate on the inner wall of the 0 is less likely to flow directly into the first airflow channel 10A and the second airflow channel 10B and accumulate there, which helps to reduce the risk of condensate leakage from the first air inlet 9101 or the second air inlet 9201, thus affecting the cleanliness and hygiene of the mist generating device. In addition, since the airflow sensing end 10C1 of the sensing channel 10C is located close to the suction channel 210, the air pressure in the sensing channel 10C can change more easily with the user's suction, which can more easily trigger the airflow sensor 51 to act. That is, it helps to improve the detection sensitivity of the airflow sensor 51, so that the airflow sensor 51 can detect the user's suction action more sensitively.

[0108] Further, please refer to Figure 3-4 In some optional embodiments of this application, the vapor generation device further includes a liquid absorber 22 made of a porous material (the porous material can be sponge, fiber cotton, porous ceramic, etc.). The liquid absorber 22 is disposed on the top surface of the liquid storage cup 3 and spaced apart from the air inlet end of the suction channel 210. The liquid absorber 22 has a first through hole 221 and a second through hole 222 spaced apart. The first through hole 221 is connected to the first air outlet end 321, and the second through hole 222 is connected to the second air outlet end 322. With this configuration, the liquid absorber 22 can absorb the condensate dripping from the inner wall of the suction channel 210, thereby further reducing the risk of condensate flowing into the first airflow channel 10A, the second airflow channel 10B, and the sensing channel 10C.

[0109] Further, please refer to Figure 1 , Figure 4 as well as Figure 11-12In some optional embodiments of this application, the vapor generation device further includes a display component 55 for displaying visual information. The display component 55 is disposed on the peripheral surface of the housing 1 and electrically connected to the electronic control component 6. It is understood here that the peripheral surface of the housing 1 includes the front surface, rear surface, left surface, and right surface of the housing 1. For example, the display component 55 is disposed on the front surface of the housing 1. In specific implementations, the structure of the display component 55 can be a liquid crystal display screen, a light-emitting diode display screen, an organic light-emitting diode display screen, etc., which can be determined according to actual usage needs. This embodiment does not impose specific limitations on this. For example, such as... Figure 4 and Figure 11 As shown, the display component 55 includes a digital tube 551 and a transparent cover plate 552. The transparent cover plate 552 is fixed to the front surface of the housing 1. The digital tube 551 is electrically connected to the control circuit board 62 of the electronic control component 6 and is disposed opposite to the transparent cover plate 552.

[0110] In this embodiment, the visual information displayed by the display component 55 includes at least one of the following: the remaining power of the battery 61, the remaining amount of vapor-forming material in the first liquid storage chamber 311, the remaining amount of vapor-forming material in the second liquid storage chamber 312, the output voltage of the battery 61, light alarm information, and preset pattern information. In this embodiment, the display component 55 allows users to intuitively obtain relevant parameter information of the vapor-generating device (such as the remaining power of the battery 61), thereby improving the user experience. In some optional embodiments, the control circuit board 62 of the electronic control component 6 can be configured to, when receiving a suction signal from the airflow sensor 51, control the display component 55 to display visual information so that the user can observe the visual information displayed by the display component 55 during suction; and, when receiving a stop signal from the airflow sensor 51, control the display component 55 to stop displaying visual information after a preset time (the preset time can be 2 seconds, 3 seconds, 5 seconds, 6 seconds, etc.) so that the user can observe the visual information displayed by the display component 55 after suction is completed.

[0111] Further, please refer to Figure 4-6 , Figure 9-11 as well as Figure 14-16In some optional embodiments of this application, the display component 55 is disposed on one side of the housing 1 along its width direction. The first air outlet 321, the airflow sensing end 10C1, and the second air outlet 322 are sequentially spaced along the width direction of the housing 1. Along the width direction of the housing 1, the first air outlet 321 is positioned closer to the display component 55 than the second air outlet 322. The vent 3134 penetrates the sidewall of the airflow sensing end 10C1 along the width direction of the housing 1 and connects to the second air outlet 322 (that is, the sensing channel 10C is connected to the suction channel 210 through the vent 3134 and the second air outlet 322). It should be noted that, exemplarily, the width direction of the housing 1 is... Figure 4 The front and back directions in the middle.

[0112] In this embodiment, considering that the vapor generator is tilted when the user uses it for suction, and to facilitate the user's observation of the visual information displayed on the display component 55 (such as a light alarm indicating low battery or insufficient remaining vapor-forming material), the user typically holds the vapor generator with the display component 55 facing upwards. Figure 5 As shown in the figure, based on this consideration, this embodiment sets the vent 3134, which connects the suction channel 210 and the sensing channel 10C, away from the display component 55. This allows the user to hold the vapor generator in a way that allows the display component 55 to face upwards for suction use. The end of the vent 3134 connected to the second air outlet 322 will tilt downwards. Thus, during the user's suction use, even if condensate slides down from the top surface of the liquid storage cup 3 along the inner wall of the second air outlet 322 (it should be noted that when the top surface of the liquid storage cup 3 is provided with liquid 22, when the liquid 22 reaches saturation, condensate will overflow), the condensate is unlikely to flow into the sensing channel 10C through the vent 3134. This further reduces the risk of the airflow sensor 51 being wetted by condensate, resulting in decreased sensitivity or even damage.

[0113] Further, please refer to Figure 9 , Figure 11 , Figure 14 , Figure 16 and Figure 18In some optional embodiments of this application, the vapor generator further includes a connector 9 installed in the housing 1. The connector 9 is made of a sealing material (such as silicone, rubber or silicone rubber). The connector 9 has a first connecting portion 91, a second connecting portion 92 and a third connecting portion 93 that are connected to each other. A first air inlet end 9101 is disposed on the surface of the first connecting portion 91, and the portion of the first connecting portion 91 with the first air inlet end 9101 is in contact with the adjusting plate 81 of the airway switch 8. A second air inlet end 9201 is disposed on the surface of the second connecting portion 92, and the portion of the second connecting portion 92 with the second air inlet end 9201 is in contact with the adjusting plate 81 of the airway switch 8. The third connecting portion 93 is sealed and fitted in one end of the sensing channel 10C. The interior of the third connecting portion 93 is provided with an installation channel 930 that communicates with the sensing channel 10C. The airflow sensor 51 is sealed and fitted in the installation channel 930.

[0114] In this embodiment, based on the above structural design, by setting a connector 9 made of sealing material, on the one hand, it is convenient to seal the airflow sensor 51 in one end of the sensing channel 10C so that when the user bites the mouthpiece 21 to suck, a pressure difference can be generated on both sides of the airflow sensor 51 so that the airflow sensor 51 can detect the user's sucking action in time; on the other hand, it can improve the airtightness between the airway switch 8 and the first air inlet 9101 and the second air inlet 9201, so that the airway switch 8 can more tightly seal the first air inlet 9101 or the second air inlet 9201, thereby better ensuring that only one airflow channel can form a sucking airflow during the user's sucking process, so as to ensure the user's sucking experience.

[0115] Further, please refer to Figure 1 , Figure 3 and Figure 11-12 In some optional embodiments of this application, the vapor generating device further includes a condition adjustment component 52 electrically connected to the electronic control component 6. The condition adjustment component 52 has an exposed second operation part 521 (exemplarily, the second operation part 521 is exposed from the bottom of the housing 1). The electronic control component 6 is configured to control the working state of the vapor generating device according to the condition adjustment signal output by the condition adjustment component 52. The control of the working state of the vapor generating device includes at least one of controlling the vapor generating device to enter the power-on state or power-off state, adjusting the atomization power of the first atomizing core 41, adjusting the atomization power of the second atomizing core 42, controlling the first atomizing core 41 to perform preheating operation, and controlling the second atomizing core 42 to perform preheating operation.

[0116] In this embodiment, by adding a condition adjustment component 52, the functionality of the mist generating device can be easily expanded, thereby improving the practicality of the mist generating device. In some optional embodiments, the condition adjustment component 52 can be a push-button control switch, in which case the second operating part 521 can be a button cap. Specifically, the condition adjustment component 52 also includes a push-button switch 522, which has a resistor R, a first conductive contact L1, a second conductive contact L2, and a button SW connected to the button cap. The first conductive contact L1 is grounded to GND through the resistor R, the second conductive contact L2 is electrically connected to the control circuit board 62 of the electronic control component 6, and the button SW is configured corresponding to the first conductive contact L1 and the second conductive contact L2. Thus, by pressing the button cap in different ways, the push-button switch 522 can be triggered to output different types of condition adjustment signals to the control circuit board 62, so that the control circuit board 62 can control the mist generating device to enter the corresponding working state.

[0117] For example, by pressing and holding the button cap for a first predetermined duration (e.g., pressing and holding for 3 seconds), the button switch 522 outputs an on / off signal to the control circuit board 62, thereby controlling the vapor generator to change from the on state to the off state or from the off state to the on state.

[0118] For example, when the device is powered on, pressing the button cap a first preset number of times within a first preset time causes the button switch 522 to output different power adjustment signals to the control circuit board 62, thereby controlling the battery 61 to output different voltages to the first atomizing core 41 or the second atomizing core 42, achieving the purpose of adjusting the atomization power of the first atomizing core 41 or the second atomizing core 42. For example, before inhaling, the output voltage of the battery 61 can be set to a first voltage (e.g., 2.6V) by pressing the button cap twice within 2 seconds, to a second voltage (e.g., 2.8V) by pressing the button cap three times within 2 seconds, and to a third voltage (e.g., 3.2V) by pressing the button cap four times within 2 seconds. Then, when the user bites the mouthpiece 21 to inhale, the airflow sensor 51 triggers the control circuit board 62 to control the battery 61 to output electrical energy to the corresponding atomizing core according to the preset voltage value, so that the corresponding atomizing core can perform atomization work with the corresponding atomization power.

[0119] For example, when the device is powered on, pressing the button cap a second preset number of times within a second preset time causes the button switch 522 to output a preheating signal to the control circuit board 62, thereby controlling the corresponding atomizing core to perform a preheating operation for a second preset duration. For instance, before inhaling, the button cap can be pressed five times within 3 seconds to trigger the button switch 522 to generate a preheating signal and output it to the control circuit board 62. When the control circuit board 62 receives the preheating signal, it controls the battery 61 to output electrical energy to the corresponding atomizing core at a default voltage value (e.g., 1.8V), so that the corresponding atomizing core performs a preheating operation for 10 seconds at the default preheating power. It can be understood that when the adjustment plate 81 of the airway switch 8 is in the first position, the first atomizing core 41 performs preheating operation, and when the adjustment plate 81 of the airway switch 8 is in the second position, the second atomizing core 42 performs preheating operation. It should be noted that the operating power of the atomizer coil during preheating is lower than that during atomization. When the atomizer coil is preheating, it does not vaporize the atomizing material it adsorbs. Instead, it preheats the atomizing material it adsorbs and the corresponding atomizing material in the reservoir to improve the fluidity of the atomizing material (especially when the viscosity of the atomizing material is high). This reduces the risk of dry burning due to insufficient liquid during subsequent atomization, which could affect the user's vaping experience.

[0120] For example, when the device is powered on, pressing the button cap a third preset number of times within a third preset time period causes the button switch 522 to output a display signal to the control circuit board 62, thereby controlling the display component 55 to display visual information for a third preset duration. For instance, before suction, the button cap can be pressed once within 0.5 seconds to trigger the button switch 522 to output a display signal to the control circuit board 62. When the control circuit board 62 receives the display signal, it controls the display component 55 to display visual information for 3 seconds.

[0121] Further, please refer to Figure 3 and Figure 12In some optional embodiments of this application, the vapor generating device further includes a first light-emitting element 53 and a second light-emitting element 54. The first light-emitting element 53 is disposed corresponding to the first liquid storage cavity 311 (exemplarily, the first light-emitting element 53 is disposed below the first liquid storage cavity 311), and the first light-emitting element 53 is electrically connected to the control circuit board 62 of the electronic control component 6. The second light-emitting element 54 is disposed corresponding to the second liquid storage cavity 312 (exemplarily, the second light-emitting element 54 is disposed below the second liquid storage cavity 312), and the second light-emitting element 54 is electrically connected to the control circuit board 62 of the electronic control component 6. In specific implementations, the first light-emitting element 53 and the second light-emitting element 54 can be in the form of RGB LED lights.

[0122] In this embodiment, based on the above structural design, by adding a first light-emitting element 53 corresponding to the first liquid storage chamber 311 and a second light-emitting element 54 corresponding to the second liquid storage chamber 312, in some specific application scenarios, users can intuitively know the current working status of the vapor generator.

[0123] For example, in some specific application scenarios, when the vapor generator goes from the off state to the on state, the control circuit board 62 controls the first light-emitting element 53 and the second light-emitting element 54 to emit green light and flash 3 times before turning off; while when the vapor generator goes from the on state to the off state, the control circuit board 62 controls the first light-emitting element 53 and the second light-emitting element 54 to emit white light and flash 3 times before turning off.

[0124] For example, in some specific application scenarios, when the adjustment plate 81 of the airway switch 8 is in the first position and the output voltage of the battery 61 is set to the first voltage by the working condition adjustment component 52, the control circuit board 62 can control the first light-emitting element 53 to emit green light and then turn off after 1 second. Moreover, when the first atomizing core 41 performs atomization work with a power corresponding to the first voltage, the first light-emitting element 53 is controlled to continuously emit green light during the user's inhalation process.

[0125] For example, in some specific application scenarios, when the adjustment plate 81 of the airway switch 8 is in the second position and the output voltage of the battery 61 is set to the second voltage by the working condition adjustment component 52, the control circuit board 62 can control the second light-emitting element 54 to emit blue light and then turn off after 1 second. Moreover, when the second atomizing core 42 performs atomization work at a power corresponding to the second voltage, the second light-emitting element 54 is controlled to continuously emit blue light during the user's inhalation process.

[0126] For example, in some specific application scenarios, when the first atomizing core 41 is preheating, the control circuit board 62 can control the first light-emitting element 53 to emit white light and flash in the manner of a breathing light. When the second atomizing core 42 is preheating, the control circuit board 62 can control the second light-emitting element 54 to emit white light and flash in the manner of a breathing light.

[0127] Further, please refer to Figure 3 In some optional embodiments of this application, the portions of the liquid storage cup 3 corresponding to the first light-emitting element 53 and the second light-emitting element 54 are both made of a light-transmitting material (such as acrylic or glass), so that the light emitted by the first light-emitting element 53 can illuminate the first liquid storage cavity 311 and the light emitted by the second light-emitting element 54 can illuminate the second liquid storage cavity 312. Thus, when the light emitted by the corresponding light-emitting element illuminates the liquid storage cavity containing the liquid vapor-forming substance, physical phenomena such as reflection, refraction, and scattering occur, allowing the user to observe the cool lighting effects produced in the liquid storage cavity through the corresponding viewing window, thereby improving the user experience.

[0128] Further, please refer to Figure 1 , Figure 3 and Figure 16 In some optional embodiments of this application, the vapor generator further includes a charging interface 56, which is located at the bottom of the housing 1 and electrically connected to the control circuit board 62 of the electronic control component 6. This configuration allows the user to conveniently charge the vapor generator when the battery 61 of the electronic control component 6 has low or depleted power.

[0129] Further, please refer to Figure 1 , Figure 7 , Figure 11 , Figure 13 and Figure 16 In some optional embodiments of this application, the housing 1 has a first window 111 and a second window 112 spaced apart. The first window 111 corresponds to the first liquid storage cavity 311, and the second window 112 corresponds to the second liquid storage cavity 312. The portions of the liquid storage cup 3 corresponding to the first window 111 and the portions corresponding to the second window 112 are both made of transparent material (such as glass or acrylic). This arrangement allows the user to not only know the remaining amount of vapor-forming substance in the first liquid storage cavity 311 and the second liquid storage cavity 312 through the display component 55, but also to directly observe the remaining amount of vapor-forming substance in the first liquid storage cavity 311 and the second liquid storage cavity 312 through the first window 111 and the second window 112, thus enabling the user to obtain information about the remaining amount of vapor-forming substance in the first liquid storage cavity 311 and the second liquid storage cavity 312 in a more diverse manner.

[0130] Further, please refer to Figure 1 , Figure 3-4 , Figure 7-11 as well as Figure 13-18 In some optional embodiments of this application, the specific structural composition of the vapor generation device may be as follows:

[0133] The liquid storage cup 3 includes a cup body 31, a bottom cover 33, and a top cover 32 (which may be made of sealing materials such as silicone or rubber) located inside the outer shell 11. The cup body 31 has a first liquid storage chamber 311, a second liquid storage chamber 312, and a partition 313 located between the first and second liquid storage chambers 311 and 312. The bottom wall of the first liquid storage chamber 311 has a first liquid outlet 3110, and the bottom wall of the second liquid storage chamber 312 has a second liquid outlet 3120. The first atomizing core 41 is sealed to the first liquid outlet 3110 via a first sealing sleeve 43 made of silicone. The second atomizing core... 42 can be sealed to the second outlet 3120 by a second sealing sleeve 44 made of silicone; the partition 313 has a first channel 3131, a second channel 3132 and a third channel 3133 arranged separately inside; the top cover 32 is sealed to the top of the cup body 31 and closes one end port of the third channel 3133 (that is, the port of the airflow sensing end 10C1); the first air outlet 321 is connected to one end port of the first channel 3131, the second air outlet 322 is connected to one end port of the second channel 3132; the inner wall of the third channel 3133 has at least one vent hole 3134; the third channel 3133 is connected to at least one A vent 3134 is connected to at least one of the first channel 3131 and the second channel 3132 (exemplarily, a vent 3134 is provided on the upper inner wall of the third channel 3133, and the third channel 3133 is connected to the upper port of the second channel 3132 through the vent 3134); the bottom cover 33 has a first atomizing chamber 331, a second atomizing chamber 332 and a connecting channel 333 arranged separately from each other. The cavity wall of the first atomizing chamber 331 has at least one first air passage 3310, and the cavity wall of the second atomizing chamber 332 has at least one second air passage 3320. The bottom cover 33 is sealed to the bottom of the cup body 31, and the first The atomizing chamber 331 is sealed and connected to the lower port of the first channel 3131, the second atomizing chamber 332 is sealed and connected to the lower port of the second channel 3132, the connecting channel 333 is sealed and connected to the lower port of the third channel 3133, the first atomizing core 41 is set corresponding to the first atomizing chamber 331, and the second atomizing core 42 is set corresponding to the second atomizing chamber 332; the bottom of the cup body 31 is sealed and fitted into the top of the bracket 12, and the first ventilation chamber 121 is connected to the first atomizing chamber 331 through the first air passage 3310, the second ventilation chamber 122 is connected to the second atomizing chamber 332 through the second air passage 3320, and the third ventilation chamber 123 is sealed and connected to the connecting channel 333;

[0134] The first airway 910, the first ventilation chamber 121, the first atomizing chamber 331, and the first channel 3131 are sequentially connected to form at least a portion of the first airflow channel 10A; the second airway 920, the second ventilation chamber 122, the second atomizing chamber 332, and the second channel 3132 are sequentially connected to form at least a portion of the second airflow channel 10B; and the third ventilation chamber 123, the connecting channel 333, and the third channel 3133 are sequentially connected to form at least a portion of the sensing channel 10C.

[0135] In this embodiment, based on the above structural design, in the first aspect, the air inlet 810 of the regulating plate 81 can be kept in communication with the outside through the ventilation gap 140 and the mounting through hole 110. This kind of hidden structural design that hides the air inlet 810 in the outer shell 11 is beneficial to improving the overall appearance of the mist generating device.

[0136] Secondly, by assembling the connector 9, the bracket 12 and the liquid storage cup 3 together, the first airflow channel 10A, the second airflow channel 10B and the sensing channel 10C, which are independent of each other, can be cleverly formed. The structural design is very ingenious.

[0137] Thirdly, since the first atomizing core 41 is located at the bottom of the first liquid storage chamber 311 and the second atomizing core 42 is located at the bottom of the second liquid storage chamber 312, the vapor-forming material in the first liquid storage chamber 311 can be consumed to the maximum extent by the first atomizing core 41 and the vapor-forming material in the second liquid storage chamber 312 can be consumed to the maximum extent by the second atomizing core 42, thereby maximizing the utilization rate of the vapor-forming material in the two liquid storage chambers.

[0138] Fourthly, this design allows for strong assemblability of the mist generating device. Specifically, when assembling the mist generating device, the relevant components can first be assembled into multiple modular structures, and then each modular structure can be assembled one by one into a complete mist generating device. For example, such as... Figure 17-18As shown, the adjusting plate 81, inner cover plate 13, connector 9, second operating part 521, battery 61, and control circuit board 62 integrating multiple electronic components can be integrated and installed on the bracket 12 to form the first module; then the top cover 32, bottom cover 33, first atomizing core 41, and second atomizing core 42 can be integrated and installed on the cup body 31 to form the second module; then the second module and the first module are assembled together by splicing, so that the bottom of the liquid storage cup 3 is sealed and fitted into the top of the bracket 12 and the two atomizing cores are electrically connected to the switch 7 respectively, thus obtaining the assembled module; Next, the assembly module is inserted into the housing 11 from the bottom, so that the bottom of the bracket 12 is fixedly engaged with the bottom of the housing 11. Then, the transparent cover plate 552 is installed on the housing 11, so that the transparent cover plate 552 corresponds to the digital tube 551. The push plate 82 is installed at the mounting through hole 110 of the housing 11, so that the push plate 82 is engaged with the adjustment plate 81. Finally, the liquid 22 is placed on the top surface of the top cover 32, and the suction nozzle 21 is inserted into the top of the housing 11, so that the liquid 22 is sandwiched between the suction nozzle 21 and the top cover 32. In this way, the assembly of the entire vapor generation device is completed.

[0139] In this embodiment, it is understood that in some specific application scenarios, in order for users to observe the remaining amount of vapor-forming substances in the first liquid storage chamber 311 and the second liquid storage chamber 312 through the first viewing window 111 and the second viewing window 112, both the first viewing window 111 and the second viewing window 112 are opened on the outer shell 11, and the cup body 31 is made of transparent material. In addition, in other specific application scenarios, in order for the light emitted by the first light-emitting element 53 to illuminate the first liquid storage chamber 311 and the light emitted by the second light-emitting element 54 to illuminate the second liquid storage chamber 312, both the cup body 31 and the bottom cover 33 are made of light-transmitting material (for example, the cup body 31 can be made of acrylic and the bottom cover 33 can be made of transparent silicone). Moreover, the bracket 12 has light-transmitting holes covered by the bottom cover 33 at the corresponding parts of the first light-emitting element 53 and the second light-emitting element 54.

[0140] In this embodiment, it should also be noted that, in some optional embodiments, the connection between the nozzle 21 and the top of the outer shell 11 can be a non-removable fixed connection (such as an interference fit), in which case the vapor generator is a disposable product; in other optional embodiments, the connection between the nozzle 21 and the top of the outer shell 11 can also be a detachable fixed connection (such as a plug-in connection), in which case the top of the liquid storage cup 3 is also provided with two spaced-apart injection holes 320, one injection hole 320 communicating with the first liquid storage chamber 311, and the other injection hole 320 communicating with the second liquid storage chamber 312, and the inside of the nozzle 21 is also provided with two spaced-apart sealing pillars 21. 1. One sealing column 211 is sealed and fitted into one of the injection holes 320, and the other sealing column 211 is sealed and fitted into the other injection hole 320. With this configuration, when the vapor-forming material in at least one of the first liquid storage chamber 311 and the second liquid storage chamber 312 is consumed, the suction nozzle 21 can be removed from the top of the outer shell 11 to expose the two injection holes 320. Then, new vapor-forming material can be added to the corresponding liquid storage chamber through the corresponding injection hole 320. After that, the suction nozzle 21 can be reinstalled and the vapor-generating device can be used for suction again. This means that the vapor-generating device can be reused, which helps to reduce the user's operating costs.

[0141] It should be noted that other details of the vapor generation device disclosed in this application can be found in the prior art, and will not be repeated here.

[0142] The above are merely preferred embodiments of this application and do not limit the scope of the patent application.
