Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to a power supply device and 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, ultrasound, or other methods. A vapor generator typically includes an atomizing core and a storage chamber for storing vapor-forming substances. The atomizing core draws vapor-forming substances from the storage chamber and heats or ultrasonically atomizes the absorbed vapor-forming substances to produce vapor for the user to inhale.

[0003] However, most aerosol generators on the market are equipped with only one atomizing core and one storage chamber. One 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

[0004] The main purpose of this application is to provide a power supply device and a vapor generator, which aims to solve the technical problem of the limited flavor of existing vapor generators.

The first sealing sleeve is sealed and fitted inside one end of the first channel and sleeved on the first airflow sensor. The second sealing sleeve is sealed and fitted inside one end of the second channel and sleeved on the second airflow sensor. The first sensing channel further includes a third channel disposed within the second housing. One end of the third channel is directly connected to the first atomizing channel, and the other end is located on the bottom surface of the second housing and is sealed and connected to the end port of the first channel away from the first airflow sensor. The second sensing channel further includes a fourth channel disposed within the second housing. One end of the fourth channel is directly connected to the second atomizing channel, and the other end is located on the bottom surface of the second housing and is sealed and connected to the end port of the second channel away from the second airflow sensor.

[0024] In some embodiments, the power assembly further includes a seal installed in the receiving cavity. The seal is made of any one of silicone, rubber, or silicone rubber.

The inner diameter of the air inlet port of the first atomizing channel is 2 to 5 times the inner diameter of the third channel. The air inlet port of the second atomizing channel and the fourth channel are both located below the second atomizing core and extend along the height direction of the second housing.

[0029] Compared with the prior art, this application has at least the following beneficial effects:

[0030] In the technical solution provided in this application, the first storage chamber can store a vapor-forming substance of one flavor, and the second storage chamber can store a vapor-forming substance of another flavor. The first atomizing core can draw a vapor-forming substance of one flavor from the first storage chamber, atomize it, and produce a vapor of that flavor. The second atomizing core can draw a vapor-forming substance of another flavor from the second storage chamber, atomize it, and produce a vapor of another flavor. When a user needs to inhale a vapor of a certain flavor, they can switch the switch to the first position and the airway switch to the first position. In this case, the first airflow sensor can trigger the electronic control unit. The device supplies electrical energy to the first atomizing core, causing it to operate and produce a vapor of one flavor. This vapor is then output to the user's mouth through the first airway and inhaled. When the user wishes to inhale a different flavor, they can switch the switch to the second position and the airway switch to the second position. In this case, the second airflow sensor triggers the electronic control component to supply electrical energy to the second atomizing core, causing it to operate and produce a vapor of another flavor. This vapor is then output to the user's mouth through the second airway and inhaled. Therefore, the atomizing device provided in this embodiment can provide users with different flavors of atomized vapor, satisfying their needs for different flavors. Furthermore, during use, the flavor of the atomized vapor can be changed simply by altering the switch position and the airway switch position, making it convenient to operate.

[0056] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0058] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, top, bottom, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0059] Furthermore, in the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "setting," "installing," "connecting," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0060] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0061] Furthermore, if the terms "and / or," "and / or," or "and / or" appear throughout the text, their meaning includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Additionally, the specification of this application describes numerous technical features distributed across various technical solutions. Listing all possible combinations of technical features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described invention, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible. For example, feature A+B+C is disclosed in one example, and feature A+B+D+E is disclosed in another example. Features C and D are equivalent technical means that serve the same purpose. Technically, only one of them needs to be used, and it is impossible to use them simultaneously. Feature E can be combined with feature C technically. Therefore, the solution A+B+C+D should not be considered as having been recorded because it is technically infeasible, while the solution A+B+C+E should be considered as having been recorded.

[0062] Please refer to the reference. Figure 1-4 , Figure 6-8 , Figure 10-11 as well as Figure 14-15 One embodiment of this application provides a vapor generation device, which includes a housing assembly 3, a first atomizing core 21, a second atomizing core 22, a first airflow sensor 11, a second airflow sensor 12, an electronic control assembly 13, a switching switch 14, and an airway switch 15, wherein:

[0063] The housing assembly 3 has independent first air passage 41, second air passage 42, first sensing channel 51, second sensing channel 52, first storage cavity 2011 and second storage cavity 2021. One end of the first sensing channel 51 is connected to the first air passage 41, and one end of the second sensing channel 52 is connected to the second air passage 42. In some specific application scenarios, the first storage cavity 2011 can store a vapor-forming substance of one flavor (such as tobacco flavored e-liquid), and the second storage cavity 2021 can store a vapor-forming substance of another flavor (such as mint flavored e-liquid).

[0064] The first atomizing core 21 is installed inside the housing assembly 3. The first atomizing core 21 can be connected to the first storage cavity 2011 through the first liquid outlet hole 2014 provided on the cavity wall of the first storage cavity 2011, so that the first atomizing core 21 can draw vapor-forming substances from the first storage cavity 2011 for atomization and produce a flavored vapor. Moreover, the first atomizing core 21 is located on the airflow path of the first air passage 41, so that the vapor produced by the first atomizing core 21 can be carried away by the suction airflow formed in the first air passage 41 and output to the user's mouth for the user to inhale.

[0065] The second atomizing core 22 is installed inside the housing assembly 3. The second atomizing core 22 can be connected to the second storage cavity 2021 through the second liquid outlet hole 2024 provided on the cavity wall of the second storage cavity 2021, so that the second atomizing core 22 can draw vapor-forming substances from the second storage cavity 2021 for atomization and produce vapor of another flavor. Moreover, the second atomizing core 22 is located on the airflow path of the second air passage 42, so that the vapor produced by the second atomizing core 22 can be carried away by the suction airflow formed in the second air passage 42 and output to the user's mouth for the user to inhale.

[0066] The first airflow sensor 11 is located at least partially within the first sensing channel 51 to detect changes in airflow within the first sensing channel 51, thereby generating a suction signal (such as a high-level signal) to indicate that the user is in the process of suctioning or a stop signal (such as a low-level signal) to indicate that the user has stopped suctioning.

[0067] The second airflow sensor 12 is located at least partially within the second sensing channel 52 to detect changes in airflow within the second sensing channel 52, thereby generating a suction signal to indicate that the user is in the process of inhaling or a stop signal to indicate that the user has stopped inhaling.

[0068] The electronic control component 13 is installed inside the housing component 3 and is electrically connected to the first atomizing core 21 and the second atomizing core 22 respectively. The electronic control component 13 is configured to supply power to the first atomizing core 21 when it receives a suction signal sent by the first airflow sensor 11, supply power to the second atomizing core 22 when it receives a suction signal sent by the second airflow sensor 12, stop supplying power to the first atomizing core 21 when it receives a stop signal sent by the first airflow sensor 11, and stop supplying power to the second atomizing core 22 when it receives a stop signal sent by the second airflow sensor 12.

[0069] A switch 14 is electrically connected to an electronic control component 13, a first airflow sensor 11, and a second airflow sensor 12. The switch 14 has a first position and a second position, and can be operably switched between the first position and the second position. When the switch 14 is in the first position, the switch 14 connects the first airflow sensor 11 to the electronic control component 13 and disconnects the second airflow sensor 12 from the electronic control component 13. When the switch 14 is in the second position, the switch 14 connects the second airflow sensor 12 to the electronic control component 13 and disconnects the first airflow sensor 11 from the electronic control component 13.

[0070] The airway switch 15 is movably connected to the housing assembly 3, and the airway switch 15 is operable to move between a first position and a second position relative to the housing assembly 3; wherein, when the airway switch 15 is moved to the first position, the air inlet port of the first airway 41 is connected to the outside and the air inlet port of the second airway 42 is closed by the airway switch 15 and isolated from the outside; when the airway switch 15 is moved to the second position, the air inlet port of the second airway 42 is connected to the outside and the air inlet port of the first airway 41 is closed by the airway switch 15 and isolated from the outside.

[0071] In this embodiment, it should be noted that, in specific implementation, the structure of the first atomizing core 21 and the second atomizing core 22 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, or other types of atomizing core structures that are mature in the field. It can be determined according to actual usage requirements. This embodiment does not impose specific restrictions on the structure of the first atomizing core 21 and the second atomizing core 22. Optionally, both the first atomizing core 21 and the second atomizing core 22 are hollow cotton atomizing cores.

[0072] In this embodiment, it should be noted that, in specific implementations, the type of switch 14 can be a rotary switch, a button switch, a touch switch (such as a touch screen), or a toggle switch (such as a single-pole double-throw 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.

[0073] In this embodiment, it should also be noted that in some optional implementations, the connection between the airway switch 15 and the housing assembly 3 can be a rotatable connection. In this case, the structure of the airway switch 15 can be a knob or an adjusting ring with an air adjustment hole. In other optional implementations, the connection between the airway switch 15 and the housing assembly 3 can also be a sliding connection. In this case, the structure of the airway switch 15 can be a slider. 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 15 and the housing assembly 3 or on the structure of the airway switch 15.

[0074] In this embodiment, it should also be noted that, in order to facilitate the user's use of the vapor generation device provided in this embodiment for suction, a suction nozzle 25 can be provided on the housing assembly 3. The suction nozzle 25 is connected to the air outlet port of the first air channel 41 and the air outlet port of the second air channel 42 respectively.

[0075] Based on the above structural design, the operating principle of the vapor generation device provided in this embodiment is as follows:

[0076] When the user only needs to inhale the vapor produced by the first atomizing core 21, they can first switch the switch 14 to the first position, which will simultaneously activate the airway switch 15 to the first position. Then, they can inhale through the mouthpiece 25. Since the air inlet of the first airway 41 is connected to the outside at this time, outside air can enter the first airway 41 through the air inlet and form a suction airflow in the first airway 41. At this time, since the air inlet of the second airway 42 is closed by the airway switch 15, outside air cannot pass through the air inlet of the second airway 42. When the vapor enters the second airway 42, it cannot form a suction airflow within the second airway 42. This prevents the vapor produced by the first atomizing core 21 from being diluted by the suction airflow formed by the second airway 42 when it is output at the mouthpiece 25, thus reducing the user's vaping experience. At the same time, since one end of the first sensing channel 51 is connected to the first airway 41 and one end of the second sensing channel 52 is connected to the second airway 42, some of the air in both the first and second sensing channels 51 will be drawn away by the user, resulting in a decrease in the vaping experience of the first sensing channel 51 and the second sensing channel 52. The airflow within the second sensing channel 52 will change (specifically, a negative pressure will form). However, since the switch 14 is in the first position, only the first airflow sensor 11 is energized by the electronic control component 13, while the second airflow sensor 12 is de-energized. Therefore, only the first airflow sensor 11 will respond to the airflow changes within the first sensing channel 51 and send a suction signal to the electronic control component 13, while the second airflow sensor 12 will not respond to the airflow changes within the second sensing channel 52 and will not send a suction signal to the electronic control component 13. The control component 13 sends a suction signal, so that the electronic control component 13 only supplies power to the first atomizing core 21 and not to the second atomizing core 22. That is, at this time, only the first atomizing core 21 is powered on and produces a vapor of a certain flavor, while the second atomizing core 22 does not work and therefore does not produce vapor. When the suction airflow in the first air passage 41 flows through the first atomizing core 21, the suction airflow will carry away the vapor produced by the first atomizing core 21 and finally output it to the user's mouth through the mouthpiece 25, so that the user can inhale the vapor of a certain flavor produced by the first atomizing core 21.

[0077] Similarly, when the user only needs to inhale the different flavor of aerosol produced by the second atomizing core 22, they simply need to switch the switch 14 to the second position and the airway switch 15 to the second position, then bite down on the mouthpiece 25 and inhale. It should be noted that the relevant principles and processes involved in the user inhaling the aerosol produced by the second atomizing core 22 are similar to those involved in the user inhaling the aerosol produced by the first atomizing core 21, and will not be elaborated upon here.

[0078] As can be seen from the above analysis, in the technical solution provided in this embodiment, due to the coordinated action of the switching switch 14, the airway switch 15, the first airflow sensor 11, and the electronic control component 13, the first atomizing core 21 can perform atomization work independently, and under the coordinated action of the switching switch 14, the airway switch 15, the second airflow sensor 12, and the electronic control component 13, the second atomizing core 22 can perform atomization work independently. That is, the first atomizing core 21 and the second atomizing core 22 can perform atomization work separately, thereby providing users with two different flavors of aerosol, satisfying users' needs for inhaling aerosol with different flavors. Moreover, during the inhalation process, the flavor of the aerosol output by the aerosol generating device can be changed simply by changing the gear state of the switching switch 14 and the position state of the airway switch 15, making it relatively convenient to operate.

[0079] Furthermore, in some optional embodiments of this application, the airway switch 15 can be a sliding, push-type structure, as detailed below:

[0080] like Figure 1-2 and Figure 6-7 As shown, the airway switch 15 includes a push plate 151 and a pusher 152. The push plate 151 is slidably connected to the housing assembly 3 by means of sliding fit, etc. The pusher 152 is fixedly connected to the push plate 151 by means of snap-fit, adhesive, integral connection, etc. The push plate 151 is provided with a first air inlet 1511 and a second air inlet 1512 that are in communication with the outside. The pusher 152 is exposed outside the housing assembly 3 for user operation. When the pusher 152 is subjected to an external force (this external force can be applied by the user to the pusher 151), the pusher 152 can be activated. When the push plate 151 is slid to the first position by the thrust of the push plate 152, the air inlet port of the first air passage 41 is connected to the first air inlet hole 1511 and thus connected to the outside, and the air inlet port of the second air passage 42 is closed by the push plate 151 and isolated from the outside; when the push plate 152 is subjected to external force and the push plate 151 is slid to the second position, the air inlet port of the second air passage 42 is connected to the second air inlet hole 1512 and thus connected to the outside, and the air inlet port of the first air passage 41 is closed by the push plate 151 and isolated from the outside.

[0081] In this embodiment, based on the above structural design, the user can selectively open the air intake port of the first air passage 41 or the air intake port of the second air passage 42 by operating the pusher 152 with their finger to push the pusher 151 to slide. This is very convenient to operate and thus helps to improve the user's operating experience.

[0082] Furthermore, please refer to the following: Figure 3-4 , Figure 6-7 and Figure 13In some optional embodiments of this application, the switch 14 is a toggle switch. The switch 14 can be connected to the push plate 151 by means of snap-fit ​​or other means, so that the switch 14 can change its gear state as the push plate 151 moves. When the push plate 151 slides to the first position, the switch 14 is in the first gear position; when the push plate 151 slides to the second position, the switch 14 is in the second gear position.

[0083] In this embodiment, a toggle switch is used as the switching switch 14 and connected to the push plate 151. When the user pushes the push plate 151 to slide, the switching switch 14 can slide relative to the housing assembly 3. This allows the electrical connection between the first airflow sensor 11 and the electronic control assembly 13 to be connected simultaneously when the air inlet port of the first airway 41 is opened (or the electrical connection between the second airflow sensor 12 and the electronic control assembly 13 to be connected simultaneously when the air inlet port of the second airway 42 is opened). In other words, the opening and closing state of the corresponding airway is associated with the on / off state of the corresponding airflow sensor. This allows the user to select the desired flavor of aerosol by operating only the airway switch 15, without having to operate the switching switch 14 and the airway switch 15 separately. This simplifies the user's operation and improves the user experience.

[0084] Furthermore, please refer to the following: Figure 3 and Figure 6-7 In some optional embodiments of this application, the push plate 151 is made of a rigid material (such as plastic or metal). The vapor generation device also includes a flexible member 16 fixed on the housing assembly 3. The flexible member 16 can be made of a flexible material with certain sealing performance, such as silicone, rubber, or silicone rubber. The flexible member 16 is provided with a first air inlet 161 and a second air inlet 162 spaced apart. The part of the flexible member 16 with the first air inlet 161 and the part with the second air inlet 162 are in elastic contact with the push plate 151. The first air inlet 161 is the air inlet port of the first air passage 41, and the second air inlet 162 is the air inlet port of the second air passage 42.

[0085] In this embodiment, the flexible element 16 can improve the airtightness between the airway switch 15 and the air inlet port of the first airway 41, as well as between the airway switch 15 and the air inlet port of the second airway 42. This allows the airway switch 15 to more tightly seal the air inlet port of the first airway 41 or the air inlet port of the second airway 42, thereby ensuring that only one airway can form a suction airflow when the user chooses to inhale one flavor of aerosol, thus improving the user's inhalation experience.

[0086] Furthermore, please refer to the following: Figure 3-4 and Figure 6-11 In some optional embodiments of this application, the push plate 151 can also slide relative to the housing assembly 3 to a third position. The push plate 151 is also provided with a third air inlet 1513 and a fourth air inlet 1514 that maintain communication with the outside. The first air inlet 1511 and the second air inlet 1512 are both located between the third air inlet 1513 and the fourth air inlet 1514. The switch 14 also has a third position. When the switch 14 is in the third position, the switch 14 simultaneously connects the first airflow sensor 11 and... Electrical connections between the electronic control components 13 and between the second airflow sensor 12 and the electronic control components 13; wherein, when the push plate 151 slides to the third position, the first air inlet 1511 is offset from the air inlet port of the first air passage 41, the second air inlet 1512 is offset from the air inlet port of the second air passage 42, the third air inlet 1513 is connected to the air inlet port of the first air passage 41, the fourth air inlet 1514 is connected to the air inlet port of the second air passage 42, and the switching switch 14 is in the third position.

[0087] In this embodiment, it should be noted that in order for the switch 14 to have three positions, in specific implementation, the switch 14 can be a toggle switch of model LS-1400M-03. Of course, the switch 14 can also be a toggle switch of other models, as long as it can meet the usage requirements. This embodiment does not impose any specific restrictions on this.

[0088] In this embodiment, based on the above structural design, users can choose to inhale one flavor of aerosol alone, or simultaneously inhale two different flavors of aerosol, thus providing users with a richer flavor experience. For example, as... Figure 3 and Figure 6-7As shown, when a user wants to inhale only one flavor of aerosol produced by the first atomizing core 21, they can push the push plate 151 to the left until the first air inlet 1511 and the first air intake 161 are connected. When a user wants to inhale only another flavor of aerosol produced by the second atomizing core 22, they can push the push plate 151 to the right until the second air inlet 1512 and the second air intake 162 are connected. When a user wants to inhale both the aerosol produced by the first atomizing core 21 and the aerosol produced by the second atomizing core 22, the push plate 151 is kept stationary, so that the push plate 151 is positioned at the third air inlet 151. The third position is where the first air inlet 161 is connected and the fourth air inlet 1514 is connected to the second air inlet 162. In this case, when the user bites the mouthpiece 25 to inhale, both the first airway 41 and the second airway 42 will form a suction airflow. At the same time, both the first airflow sensor 11 and the second airflow sensor 12 will send a suction signal to the electronic control component 13, so that the electronic control component 13 supplies power to both the first atomizing core 21 and the second atomizing core 22, so that both the first atomizing core 21 and the second atomizing core 22 perform atomization work due to power supply, thereby allowing the user to inhale two different flavors of aerosol at the same time.

[0089] Furthermore, in some optional embodiments of this application, the specific structural composition of the electronic control component 13 may be as follows:

[0090] Specifically, such as Figure 3-4 and Figure 12-13 As shown, the electronic control component 13 includes a battery 133, a microcontroller unit 134 (MCU), a first switching transistor 131, and a second switching transistor 132. The microcontroller 134 is electrically connected to the battery 133, the first switching transistor 131, the second switching transistor 132, and the switch 14. The first atomizing core 21 is electrically connected to the first switching transistor 131, and the second atomizing core 22 is electrically connected to the second switching transistor 132.

[0091] In this embodiment, it should be noted that, in specific implementations, the first switching transistor 131 and the second switching transistor 132 can be diodes, transistors, metal-oxide-semiconductor field-effect transistors, etc., as long as they meet the usage requirements. This embodiment does not impose specific restrictions on the types of the first switching transistor 131 and the second switching transistor 132. Furthermore, in specific implementations, to facilitate the installation and use of the electronic control component 13, the electronic control component 13 also includes a first circuit board 137, on which the microcontroller 134, the first switching transistor 131, the second switching transistor 132, the switch 14, the first airflow sensor 11, and the second airflow sensor 12 are all integrated.

[0092] In this embodiment, based on the above structural design, when the microcontroller 134 receives a suction signal from the first airflow sensor 11, the microcontroller 134 controls the first switch 131 to turn on, thereby enabling the first atomizing core 21 to connect to the battery 133 and perform atomization. When the microcontroller 134 receives a suction signal from the second airflow sensor 12, the microcontroller 134 controls the second switch 132 to turn on, thereby enabling the second atomizing core 22 to connect to the battery 133 and perform atomization. That is, the first atomizing core 21 and the second atomizing core 22 can each perform atomization independently.

[0093] Furthermore, in some optional embodiments of this application, in order to enable the electronic components such as the electronic control component 13, the first airflow sensor 11, the second airflow sensor 12, and the switching switch 14 to be reused, and to avoid the entire mist generation device being discarded because it can no longer be used for suction after the mist-forming material in the first storage chamber 2011 and the second storage chamber 2021 has been consumed, the mist generation device can be designed with a detachable modular structure, as follows:

[0094] Please refer to the reference. Figure 1-15 The vapor generation device includes a power supply assembly 1 and an atomizing assembly 2; the housing assembly 3 includes a first housing 10 and a second housing 20; the first air passage 41 includes a first atomizing channel 2012 and a first air intake channel 101; the second air passage 42 includes a second atomizing channel 2022 and a first air intake channel 102; the first sensing channel 51 includes a first channel 103; and the second sensing channel 52 includes a second channel 104, wherein:

[0095] Power supply assembly 1 includes a first housing 10, a first airflow sensor 11, a second airflow sensor 12, a switch 14, an airway switch 15, and an electronic control assembly 13 installed inside the first housing 10. The airway switch 15 is movably connected to the first housing 10. The first housing 10 has independent first air intake channels 101, 102, 103, and 104. The air intake port of the first air intake channel 101 is the air intake port of the first airway 41, and the air intake port of the first air intake channel 102 is the air intake port of the second airway 42. The first airflow sensor 11 is sealed and installed in one end of the first channel 103. One end of channel 103 away from the first airflow sensor 11 is connected to the first air intake channel 101 or the first atomizing channel 2012. The second airflow sensor 12 is sealed and installed in one end of the second channel 104. The other end of the second channel 104 away from the second airflow sensor 12 is connected to the first air intake channel 102 or the second atomizing channel 2022. The top of the first housing 10 is provided with a receiving cavity 105 for accommodating at least part of the atomizing component 2. The bottom wall of the receiving cavity 105 is provided with a first electrode assembly 135 and a second electrode assembly 136 spaced apart. The first electrode assembly 135 and the second electrode assembly 136 are both electrically connected to the electronic control component 13.

[0096] The atomizing assembly 2 includes a first atomizing core 21, a second atomizing core 22, and a second housing 20. The second housing 20 contains independent first atomizing channels 2012 and 2022, a first storage chamber 2011, and a second storage chamber 2021. A mouthpiece 25 is located at the top of the second housing 20, and the bottom of the second housing 20 is detachably installed within the receiving cavity 105 of the first housing 10. The first atomizing core 21 is installed within the first atomizing channel 2012 and is electrically connected to the first electrode assembly 135. The second atomizing core... 22 is installed in the second atomizing channel 2022 and electrically connected to the second electrode assembly 136. The air outlet port of the first atomizing channel 2012 is connected to the mouthpiece 25. The air inlet port of the first atomizing channel 2012 is located on the bottom surface of the second housing 20 and is sealed and connected to the air outlet port of the first air inlet channel 101. The air outlet port of the second atomizing channel 2022 is connected to the mouthpiece 25. The air inlet port of the second atomizing channel 2022 is located on the bottom surface of the second housing 20 and is sealed and connected to the air outlet port of the first air inlet channel 102.

[0097] In this embodiment, it should be noted that the detachable connection between the first housing 10 and the second housing 20 can be a magnetic connection, a plug-in connection, a snap-fit ​​connection, etc., as long as the bottom of the second housing 20 can be detachably installed in the receiving cavity 105 of the first housing 10. This embodiment does not impose any specific restrictions on this.

[0098] In this embodiment, it should also be noted that the electrical connection between the first atomizing core 21 and the first electrode assembly 135 can be a direct electrical connection or an indirect electrical connection. Similarly, the electrical connection between the second atomizing core 22 and the second electrode assembly 136 can be a direct electrical connection or an indirect electrical connection. This embodiment does not impose specific restrictions on the specific electrical connection between the first atomizing core 21 and the first electrode assembly 135 or the specific electrical connection between the second atomizing core 22 and the second electrode assembly 136. When the electrical connection between the first atomizing core 21 and the first electrode assembly 135 and the electrical connection between the second atomizing core 22 and the second electrode assembly 136 are both direct electrical connections, the structure of the first electrode assembly 135 and the second electrode assembly 136 can both be metal conductive pillars. When the bottom of the second housing 20 is inserted into the receiving cavity 105 of the first housing 10, the upper end of the first set of metal conductive pillars can be inserted into the bottom of the second housing 20 and contact the electrode pins of the first atomizing core 21, and the upper end of the second set of metal conductive pillars can be inserted into the bottom of the second housing 20 and contact the electrode pins of the second atomizing core 22. When the electrical connection between the first atomizing core 21 and the first electrode assembly 135, and the electrical connection between the second atomizing core 22 and the second electrode assembly 136 are both indirect electrical connections, as shown in Figures 1 and 2, the first electrode assembly 135 and the second electrode assembly 136 can both be conductive spring pins. At the same time, a third electrode assembly 23 and a fourth electrode assembly 24 can be exposed at the bottom of the second housing 20. The third electrode assembly 23 can be a conductive pin that is pressed against the electrode leads of the first atomizing core 21, and the fourth electrode assembly 24 can be a conductive pin that is pressed against the electrode leads of the second atomizing core 22. When the bottom of the second housing 20 is inserted into the receiving cavity 105 of the first housing 10, the two sets of conductive spring pins and the two sets of conductive pins make elastic contact with each other.

[0099] In this embodiment, based on the above structural design, after the vapor-forming substances in the first storage chamber 2011 and the second storage chamber 2021 are consumed, the atomizing component 2 can be detached from the power supply component 1, and then the new atomizing component 2 can be assembled with the power supply component 1 to form a new vapor-generating device for continued use without having to discard the entire vapor-generating device. That is, the power supply component 1, which includes components such as the electronic control component 13, the first airflow sensor 11, the second airflow sensor 12, and the switching switch 14, can be reused, thereby helping to reduce the user's operating costs.

[0100] Furthermore, please refer to the following: Figure 3 , Figure 7-11 and Figure 14-15In some optional embodiments of this application, the power supply assembly 1 further includes a hollow through-hole first sealing sleeve 171 and a hollow through-hole second sealing sleeve 172. The first sealing sleeve 171 is sealed and fitted inside one end of the first channel 103 and sleeved on the first airflow sensor 11. The second sealing sleeve 172 is sealed and fitted inside one end of the second channel 104 and sleeved on the second airflow sensor 12. That is, the first airflow sensor 11 is indirectly sealed and installed inside one end of the first channel 103 through the first sealing sleeve 171, and the second airflow sensor 12 is indirectly sealed and installed inside one end of the second channel 104 through the second sealing sleeve 172. The materials of the first sealing sleeve 171 and the second sealing sleeve 172 can be... Flexible sealing materials such as silicone, rubber, and silicone rubber are used; the first sensing channel 51 also includes a third channel 2013 disposed in the second housing 20, one end of the third channel 2013 is directly connected to the first atomizing channel 2012, and the other end of the third channel 2013 is located on the bottom surface of the second housing 20 and is sealed and connected to the end port of the first channel 103 away from the first airflow sensor 11; the second sensing channel 52 also includes a fourth channel 2023 disposed in the second housing 20, one end of the fourth channel 2023 is directly connected to the second atomizing channel 2022, and the other end of the fourth channel 2023 is located on the bottom surface of the second housing 20 and is sealed and connected to the end port of the second channel 104 away from the second airflow sensor 12.

[0101] In this embodiment, the first sealing sleeve 171 facilitates the sealed installation of the first airflow sensor 11 within one end of the first channel 103. Furthermore, during the process of a user biting the mouthpiece 25 to inhale the vapor produced by the first atomizing core 21, a pressure difference is more easily generated between the upper and lower sides of the first airflow sensor 11. This allows the first airflow sensor 11 to more sensitively detect the user's inhalation action (i.e., the first airflow sensor 11 can more sensitively detect changes in airflow within the first channel 103 caused by the user's inhalation). Similarly, the second sealing sleeve 172 facilitates the sealed installation of the second airflow sensor 12 within one end of the second channel 104. Moreover, during the process of a user biting the mouthpiece 25 to inhale the vapor produced by the second atomizing core 22, a pressure difference is more easily generated between the upper and lower sides of the second airflow sensor 12. This allows the second airflow sensor 12 to more sensitively detect the user's inhalation action (i.e., the second airflow sensor 12 can more sensitively detect changes in airflow within the second channel 104 caused by the user's inhalation).

[0102] In this embodiment, it should be further explained that, compared to connecting the end port of the first channel 103 away from the first airflow sensor 11 to the first air intake channel 101 (equivalent to setting the position connecting the first air passage 41 and the first sensing channel 51 in the power supply assembly 1), this embodiment connects the end port of the first channel 103 away from the first airflow sensor 11 to the first atomizing channel 2012 through the third channel 2013. This is equivalent to extending the position connecting the first air passage 41 and the first sensing channel 51 to the atomizing assembly 2 closer to the mouthpiece 25. In this way, when the user bites the mouthpiece 25 and inhales the vapor produced by the first atomizing core 21, the first airflow sensor 11 can more sensitively detect the changes in airflow in the first channel 103 caused by the user's inhalation. Similarly, compared to connecting the end of the second channel 104 away from the second airflow sensor 12 to the first air intake channel 102 (equivalent to setting the position connecting the second air passage 42 and the second sensing channel 52 in the power supply assembly 1), this embodiment connects the end of the second channel 104 away from the second airflow sensor 12 to the second atomization channel 2022 through the fourth channel 2023. This is equivalent to extending the position connecting the second air passage 42 and the second sensing channel 52 to the atomization assembly 2 closer to the mouthpiece 25. In this way, when the user bites the mouthpiece 25 and inhales the vapor produced by the second atomization core 22, the second airflow sensor 12 can more sensitively detect the changes in airflow in the second channel 104 caused by the user's inhalation.

[0103] Furthermore, please refer to the following: Figure 3 , Figure 8 and Figure 10-11 In some optional embodiments of this application, the power supply assembly 1 further includes a seal 173 installed in the receiving cavity 105. The seal 173 is made of any one of silicone, rubber, or silicone rubber. The seal 173 is disposed opposite to the inlet of the receiving cavity 105 and elastically contacts the bottom surface of the second housing 20. The air outlet of the first air inlet channel 101, the air outlet of the first air inlet channel 102, the end port of the first channel 103 away from the first airflow sensor 11, and the end port of the second channel 104 away from the second airflow sensor 12 are all located on the side of the seal 173 that contacts the second housing 20.

[0104] In this embodiment, the sealing element 173 facilitates the sealed connection between the first air intake channel 101 and the first atomizing channel 2012, the first air intake channel 102 and the second atomizing channel 2022, the first channel 103 and the third channel 2013, and the second channel 104 and the fourth channel 2023. Specifically, by inserting the bottom of the second housing 20 into the receiving cavity 105 of the first housing 10 and pressing the bottom surface of the second housing 20 against the sealing element 173, the sealed connection between the first air intake channel 101 and the first atomizing channel 2012, the first air intake channel 102 and the second atomizing channel 2022, the first channel 103 and the third channel 2013, and the second channel 104 and the fourth channel 2023 can be achieved.

[0105] Furthermore, considering that when the user stops inhaling the vapor produced by the first atomizing core 21, some vapor will remain in the first atomizing channel 2012 and flow back downwards. If most of this vapor flows back into the first channel 103 and condenses to form condensate, the condensate may come into contact with the first airflow sensor 11 and cause damage. To reduce the risk of damage to the first airflow sensor 11 due to contact with condensate, please refer to the following... Figure 3 and Figure 14-15 In some optional embodiments of this application, the air inlet port of the first atomizing channel 2012 and the third channel 2013 are both located below the first atomizing core 21 and extend along the height direction of the second housing 20. Moreover, the inner diameter of the air inlet port of the first atomizing channel 2012 is 2 to 5 times the inner diameter of the third channel 2013. For example, assuming the inner diameter of the third channel 2013 is 1 mm, the inner diameter of the air inlet port of the first atomizing channel 2012 can be 2 mm, 3 mm, 4 mm, 5 mm, etc. With this configuration, since the inner diameter of the air inlet port of the first atomizing channel 2012 is 2 to 5 times the inner diameter of the third channel 2013, when the user stops inhaling the vapor produced by the first atomizing core 21, most of the vapor remaining in the first atomizing channel 2012 will tend to flow back into the first air intake channel 101 through the air inlet port of the first atomizing channel 2012 with a larger inner diameter, rather than flowing back into the first channel 103 through the third channel 2013 with a smaller inner diameter. This reduces the risk of condensation forming in the first channel 103, and consequently reduces the risk of damage to the first airflow sensor 11 due to contact with condensation.

[0106] Similarly, please refer to the reference. Figure 3 and Figure 14-15The air inlet of the second atomizing channel 2022 and the fourth channel 2023 are both located below the second atomizing core 22 and extend along the height direction of the second housing 20. The inner diameter of the air inlet of the second atomizing channel 2022 is 2 to 5 times the inner diameter of the fourth channel 2023. For example, assuming the inner diameter of the fourth channel 2023 is 1 mm, the inner diameter of the air inlet of the second atomizing channel 2022 can be 2 mm, 3 mm, 4 mm, 5 mm, etc. With this configuration, since the inner diameter of the air inlet port of the second atomizing channel 2022 is 2 to 5 times the inner diameter of the fourth channel 2023, when the user stops inhaling the vapor produced by the second atomizing core 22, most of the vapor remaining in the second atomizing channel 2022 will tend to flow back into the first air inlet channel 102 through the air inlet port of the second atomizing channel 2022 with a larger inner diameter, rather than flowing back into the second channel 104 through the fourth channel 2023 with a smaller inner diameter. This reduces the risk of condensation forming in the second channel 104, and consequently reduces the risk of damage to the second airflow sensor 12 due to contact with condensation.

[0107] Furthermore, please refer to the following: Figure 3 and Figure 7-11 In some optional embodiments of this application, the upper port of the first sealing sleeve 171 is offset from the port of the first channel 103 furthest from the first airflow sensor 11. This configuration prevents condensation from forming on the inner wall of the third channel 2013, thus reducing the risk of damage to the first airflow sensor 11 due to contact with condensation. Similarly, the upper port of the second sealing sleeve 172 is offset from the port of the second channel 104 furthest from the second airflow sensor 12.

The second circuit board 193 is electrically connected to the battery 133, and the display screen 194 is electrically connected to the microcontroller 134 on the first circuit board 137. A charging interface 191 and a push-button power adjustment switch 192 are mounted on the second circuit board 193. Both the charging interface 191 and the power adjustment switch 192 are exposed from the bottom of the first housing 10. In this embodiment, the display screen 194 can be used to display information such as the remaining charge of the battery 133, the output power of the battery 133, the remaining amount of vapor-forming material in the first storage cavity 2011, and the remaining amount of vapor-forming material in the second storage cavity 2021. The charging interface 191 allows the user to conveniently charge the battery 133 using a charger. The power adjustment switch 192 can be used to adjust the output power of the battery 133.

[0111] Furthermore, in some optional embodiments of this application, the detachable connection between the first housing 10 and the second housing 20 can be achieved in the following ways:

[0112] Specifically, please refer to the following: Figure 2 , Figure 10 and Figure 14 The second housing 20 has at least two spaced elastic protrusions 203 and at least two protrusions 204 extending along the height direction of the second housing 20 on its side wall. The receiving cavity 105 has at least two spaced slots 1051 and at least two grooves 1052 extending along the height direction of the first housing 10. The at least two elastic protrusions 203 are engaged with the at least two slots 1051 in a one-to-one correspondence, and the at least two protrusions 204 are slidably engaged with the at least two grooves 1052 in a one-to-one correspondence. This configuration allows the user to remove and install the atomizing component 2 by inserting and removing it. In specific implementation, to ensure that the elastic protrusions 203 can elastically deform when squeezed by the inner wall of the receiving cavity 105, the material of the elastic protrusions 203 can be plastic. In addition, to improve the smoothness of inserting and removing the atomizing component 2, the shape of the elastic protrusions 203 can be hemispherical.

[0113] Furthermore, please refer to the following: Figure 2-3 and Figure 14-16In some optional embodiments of this application, the second housing 20 includes a first housing portion 201 and a second housing portion 202 of the same shape and size. The first housing portion 201 and the second housing portion 202 can be joined together by means of contact, snap-fit, sliding fit, etc. The first housing portion 201 is provided with a first atomizing channel 2012 and a first storage cavity 2011. The second housing portion 202 is provided with a second atomizing channel 2022 and a second storage cavity 2021. The mouthpiece 25 includes a first mouth portion 251 and a second mouth portion 252 of the same shape and size. The first mouth portion 251 and the second mouth portion 252 can be joined together by means of contact, snap-fit, sliding fit, etc. The first mouth portion 251 is disposed on the top of the first housing portion 201 and is connected to the air outlet port of the first atomizing channel 2012. The second mouth portion 252 is disposed on the top of the second housing portion 202 and is connected to the air outlet port of the second atomizing channel 2022. Compared to designing the second housing 20 as a non-removable, one-piece structure, this embodiment uses two independent and separable housing structures for the second housing 20 (equivalent to designing the atomizing component 2 as two independent and separable atomizing modules). This allows the user to continue inhaling different flavors of atomized vapor after the vapor-forming material in either the first storage chamber 2011 or the second storage chamber 2021 is depleted. Only the portion of the housing where the vapor-forming material has been depleted needs to be replaced, without replacing the entire atomizing component 2, thus improving the user experience. In practice, to facilitate mass production and reduce the production cost of the atomizing component 2, the two modular structures used to assemble the atomizing component 2 can be designed to be identical.

[0114] Correspondingly, embodiments of this application also provide a power supply device, which is used to connect with the atomizing component 2 in the vapor generating device of any of the above embodiments (such as...). Figure 1-3 and Figure 14-16 (As shown) can be detachably assembled and used, and the power supply device is the power supply component 1 in the vapor generator of any of the above embodiments (such as...). Figure 1-13 (As shown).

[0115] In this embodiment, it should be noted that other contents of the power supply device provided in this embodiment can be found in the description of the power supply component 1 in the above-mentioned vapor generation device embodiment, and will not be repeated here.

[0116] It should be noted that other details of the power supply device and vapor generation device disclosed in this application can be found in the prior art, and will not be repeated here.

[0117] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. All equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
