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 atomizes vapor-forming substances such as e-liquid and medicinal liquids into vapor through electric heating. A vapor generator typically includes an atomizing section for generating vapor and a power supply section for providing power to the atomizing section. Depending on whether the atomizing section is replaceable, vapor generators can be divided into disposable vapor generators and refillable vapor generators. Disposable vapor generators usually employ a closed design where the atomizing section and power supply section are integrated. When the vapor-forming substance stored in the atomizing section is depleted, the entire vapor generator must be discarded, resulting in resource waste and environmental degradation. Refillable vapor generators, on the other hand, generally employ a design where the atomizing section and power supply section are detachable. When the vapor-forming substance stored in the atomizing section is depleted, only a new atomizing section needs to be replaced for repeated use, without needing to discard the power supply section. Therefore, compared to disposable vapor generators, refillable vapor generators not only reduce user costs but are also more environmentally friendly.

[0003] However, most replaceable aerosol generators currently on the market generally suffer from the following problems:

[0004] Since the nozzle is usually integrated with the atomizing part, when the atomizing part is replaced, the nozzle, which is integrated with the atomizing part, is also discarded, resulting in waste of the nozzle. This not only increases the user's operating costs but is also detrimental to the environment. Utility Model Content

[0024] Compared with the prior art, this application has at least the following beneficial effects:

[0025] The vapor-generating device provided in this application includes three independent structures: a housing, an atomizing module for atomizing the vapor-forming substance, and a power supply module for providing electrical energy to the atomizing module. The nozzle is located at one end of the housing, while the atomizing module does not have a nozzle. The power supply module and the atomizing module are detachably connected to form an atomizing body. The atomizing body is detachably installed in the housing cavity of the housing, such that the vapor outlet of the atomizing module is connected to the nozzle, and the bottom cover of the power supply module protrudes from the opening of the housing. With this configuration, when the atomizing module needs to be replaced, the entire atomizing body can first be removed from the housing cavity by operating the bottom cover. Then, the atomizing module is detached from the power supply module. Next, the new atomizing module and the power supply module are assembled to form a new atomizing body. Finally, the new atomizing body is inserted into the housing cavity of the housing through the opening of the housing, so that the vapor outlet of the atomizing module is connected to the nozzle, and the bottom cover of the power supply module protrudes from the opening of the housing. This completes the entire atomizing module replacement process. Since the nozzle can remain on the outer casing and continue to be used during the replacement of the atomizing module, instead of being discarded with the replacement of the atomizing module, the waste of the nozzle can be avoided. This not only helps to reduce the user's operating costs, but also benefits the environment. In other words, the vapor generating device provided in this application has the advantages of low operating costs and good environmental performance. Attached Figure Description

[0057] 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

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] Please refer to Figure 1-9 An embodiment of this application provides a vapor generating device, which includes an outer shell 1 and an atomizing body 2. One end of the outer shell 1 along its height direction is provided with a nozzle 10, and the other end of the outer shell 1 away from the nozzle 10 is provided with an opening 11 opposite to the nozzle 10. The interior of the outer shell 1 is provided with a receiving cavity 12, which is located between the nozzle 10 and the opening 11 and is connected to the opening 11.

[0064] The atomizing body 2 includes an atomizing module 3 for atomizing vapor-forming substances and a power supply module 4 for providing power to the atomizing module 3. The atomizing module 3 has a mist outlet 3120 for outputting vapor at one end along its height direction. The power supply module 4 has a bottom cover 42 at one end along its height direction. The end of the power supply module 4 away from the bottom cover 42 is detachably connected to the end of the atomizing module 3 away from the mist outlet 3120.

[0065] The atomizing body 2 is detachably installed in the receiving cavity 12, wherein the atomizing module 3 is located in the receiving cavity 12 and the mist outlet 3120 is connected to the mouthpiece 10, a portion of the power supply module 4 is located in the receiving cavity 12, and the bottom cover 42 is exposed from the opening 11 of the outer shell 1 so that the user can disassemble the atomizing body 2.

[0066] In this embodiment, it should be noted that, in specific implementation, the connection between the suction nozzle 10 and the outer shell 1 can be a detachable connection (such as a threaded connection, a snap-fit ​​connection, etc.) or a non-detachable integral connection (for example, the suction nozzle 10 and the outer shell 1 are an integrally injection-molded structure). This can be determined according to actual usage needs. This embodiment does not impose specific limitations on the specific connection method between the suction nozzle 10 and the outer shell 1. Furthermore, in specific implementation, the shape of the outer shell 1 can be rod-shaped, box-shaped, etc., which can be determined according to actual usage needs. This embodiment also does not impose specific limitations on the specific shape of the outer shell 1. For example, as... Figure 1-2 as well as Figure 5-6 As shown, the outer shell 1 is a rod-shaped structure, and the outer shell 1 is integrally connected with the nozzle 10. This design is beneficial for the miniaturization of the vapor generator, making it easier for users to carry and use, and also helps to reduce the manufacturing cost of the parts of the vapor generator.

[0067] In this embodiment, it should also be noted that, in specific implementation, the detachable connection between the atomizing module 3 and the power supply module 4 can be a magnetic connection, a threaded connection, a snap-fit ​​connection, a plug-in connection, etc., as long as the detachable connection between the atomizing module 3 and the power supply module 4 can be achieved. This embodiment does not impose any specific restrictions on this.

[0068] In this embodiment, it should also be noted that, in specific implementation, the detachable connection between the atomizing body 2 and the outer shell 1 can be a magnetic connection, a threaded connection, a snap-fit ​​connection, a plug-in connection, etc., as long as a detachable connection between the atomizing body 2 and the outer shell 1 can be achieved. This embodiment does not impose specific limitations on this. It should be further noted that the detachable connection between the outer shell 1 and the atomizing body 2 can specifically be a detachable connection between the atomizing module 3 and the outer shell 1, or a detachable connection between the power supply module 4 and the outer shell 1, or both a detachable connection between the atomizing module 3 and the outer shell 1 and between the power supply module 4 and the outer shell 1. As long as a detachable connection between the outer shell 1 and the entire atomizing body 2 can be achieved, this embodiment does not impose specific limitations on this.

[0069] In this embodiment, based on the above structural design, when the atomizing module 3 needs to be replaced, the entire atomizing body 2 can be removed from the receiving cavity 12 of the outer shell 1 by operating the bottom cover 42. Then, the atomizing module 3 is detached from the power supply module 4. Next, the new atomizing module 3 is assembled with the power supply module 4 to form a new atomizing body 2. Finally, the new atomizing body 2 is inserted into the receiving cavity 12 of the outer shell 1 through the opening 11, so that the mist outlet 3120 of the atomizing module 3 is connected to the mouthpiece 10 and the bottom cover 42 of the power supply module 4 is exposed through the opening 11 of the outer shell 1. In this way, the entire replacement process of the atomizing module 3 can be completed. Since the mouthpiece 10 can be retained on the outer shell 1 for continued use during the replacement of the atomizing module 3 and is not discarded with the replacement of the atomizing module 3, the waste of the mouthpiece 10 can be avoided. This not only helps to reduce the user's operating costs, but also benefits the environment. That is, the vapor generating device provided in this embodiment has the advantages of low operating costs and good environmental performance.

[0070] Further, please refer to Figure 2 , Figure 5 , Figure 7 as well as Figure 23-24 In some optional embodiments of this application, a first connecting structure 1A is provided on the wall of the outer shell 1, and a second connecting structure 4A is provided on the outer wall of the power supply module 4. The first connecting structure 1A and the second connecting structure 4A are detachably connected, thereby realizing a detachable connection between the outer shell 1 and the atomizing body 2. In this embodiment, considering that the weight of the power supply module 4 is usually greater than the weight of the atomizing module 3, causing the center of gravity of the atomizing body 2 to be located on the power supply module 4, this embodiment provides a detachable connecting structure between the outer shell 1 and the power supply module 4. Compared to providing the first connecting structure 1A on the inner wall of the outer shell 1 and the second connecting structure 4A on the outer wall of the atomizing module 3, this is beneficial to improving the connection stability between the atomizing body 2 and the outer shell 1. In this embodiment, it can be understood that when the detachable connection between the outer shell 1 and the atomizing body 2 is a threaded connection, the specific structural form of the first connecting structure 1A is an internal thread, and the specific structural form of the second connecting structure 4A is an external thread.

[0071] Furthermore, in some optional embodiments of this application, when the detachable connection between the outer shell 1 and the atomizing body 2 is a snap-fit ​​connection, the structural forms of the first connection structure 1A and the second connection structure 4A can be as follows:

[0072] Specifically, please refer to the following: Figure 1-2 , Figure 5 and Figure 7The first connecting structure 1A includes a slot 13 disposed on the inner peripheral wall of the outer shell 1, and the second connecting structure 4A includes an elastic protrusion 4210 disposed on the outer peripheral wall of the power supply module 4. The elastic protrusion 4210 engages with the slot 13, thereby realizing a detachable connection between the outer shell 1 and the atomizing body 2.

[0073] In this embodiment, it is understood that when it is necessary to remove the entire atomizing body 2 from the receiving cavity 12 of the outer shell 1, the user only needs to hold the outer shell 1 with one hand and pinch the bottom cover 42 with the other hand and apply a pulling force in the direction away from the mouthpiece 10, so that the elastic protrusion 4210 disengages from the slot 13, and the entire atomizing body 2 can be pulled out from the receiving cavity 12 of the outer shell 1; and when it is necessary to assemble the atomizing body 2 and the outer shell 1 to form a complete atomizing device for use, Simply insert the atomizing body 2 into the receiving cavity 12 of the outer shell 1 through the opening 11 of the outer shell 1, so that the mist outlet 3120 of the atomizing module 3 is connected to the mouthpiece 10, the elastic protrusion 4210 is inserted into the slot 13 of the outer shell 1, and the bottom cover 42 of the power supply module 4 is exposed from the opening 11 of the outer shell 1. In other words, the user only needs to pinch the bottom cover 42 to insert and remove the atomizing body 2 to realize the mutual assembly and disassembly between the atomizing body 2 and the outer shell 1, which is very convenient to operate.

[0074] In this embodiment, it should be noted that, in specific implementation, to ensure the elastic protrusion 4210 is elastic so that it can undergo elastic deformation when compressed by the inner wall of the outer shell 1, the elastic protrusion 4210 can be made of elastic plastic, such as acrylonitrile-butadiene-styrene copolymer (ABS), nylon, polystyrene, polypropylene, etc. Furthermore, in specific implementation, to make it easier for the user to insert and remove the atomizing body 2, the surface of the elastic protrusion 4210 that contacts the outer shell 1 can be set as a rounded surface.

[0075] In this embodiment, it should also be noted that, in some optional implementations, the elastic protrusion 4210 can be configured to surround the power supply module 4 circumferentially (i.e., the elastic protrusion 4210 is an annular protrusion), and correspondingly, the slot 13 is an annular groove. In other optional implementations, the elastic protrusion 4210 can also be configured as multiple strip-shaped protrusions extending circumferentially along the power supply module 4 and spaced apart from each other, and correspondingly, the slot 13 can be configured as multiple strip-shaped grooves extending circumferentially along the outer shell 1 and spaced apart from each other. Compared to configuring the slot 13 as an annular groove, configuring the slot 13 as multiple strip-shaped grooves extending circumferentially along the outer shell 1 and spaced apart from each other helps to reduce the risk of the inner wall of the outer shell 1 being scratched by the mold during demolding when the outer shell 1 is molded by injection molding.

[0076] Furthermore, please refer to the following: Figure 2 , Figure 5 and Figure 7 In some optional embodiments of this application, when the elastic protrusion 4210 is a plurality of mutually spaced strip protrusions, and the slot 13 is a plurality of mutually spaced strip grooves, the outer peripheral wall of the power supply module 4 is also provided with a positioning protrusion 4211 located between two of the elastic protrusions 4210. The positioning protrusion 4211 extends along the height direction of the power supply module 4, and the inner peripheral wall of the outer shell 1 is also provided with a positioning groove 14 located between two of the slots 13. The positioning groove 14 extends from the end of the outer shell 1 away from the nozzle 10 toward the direction close to the nozzle 10, and the positioning protrusion 4211 slides into the positioning groove 14. With this configuration, during the process of inserting the atomizing body 2 into the receiving cavity 12 of the outer shell 1, the positioning protrusion 4211 can be aligned with the positioning groove 14 first, and then the atomizing body 2 can be inserted into the receiving cavity 12 of the outer shell 1. This facilitates ensuring that each elastic protrusion 4210 can be engaged with each slot 13 one by one.

[0077] Furthermore, in some other optional embodiments of this application, when the detachable connection between the outer shell 1 and the atomizing body 2 is a snap-fit ​​connection, the structural forms of the first connection structure 1A and the second connection structure 4A can also be as follows:

[0078] Specifically, please refer to the following: Figure 10 as well as Figure 18-22 The first connecting structure 1A includes a first annular groove 15 disposed on the inner peripheral wall of the outer shell 1, and the second connecting structure 4A includes an elastic metal coil 48 with a notch 480 and a second annular groove 4212 disposed on the outer peripheral wall of the power supply module 4. The elastic metal coil 48 is loosely installed in the second annular groove 4212 and engages with the first annular groove 15, thereby realizing a detachable connection between the outer shell 1 and the atomizing body 2. In specific implementations, the material of the elastic metal coil 48 can be iron, copper, stainless steel, spring steel, beryllium bronze, etc., as long as it meets the usage requirements. This embodiment does not impose specific limitations on this.

[0079] In this embodiment, based on the above structural design, when it is necessary to remove the entire atomizing body 2 from the receiving cavity 12 of the outer shell 1, the user only needs to hold the outer shell 1 with one hand and pinch the bottom cover 42 with the other hand and apply a pulling force in the direction away from the mouthpiece 10, so that the elastic metal coil 48 is dislodged from the first annular groove 15, and the entire atomizing body 2 can be pulled out from the receiving cavity 12 of the outer shell 1; and when it is necessary to assemble the atomizing body 2 and the outer shell 1 to form a complete vapor generating device for use... Simply insert the atomizing body 2 into the receiving cavity 12 of the outer shell 1 through the opening 11 of the outer shell 1, so that the mist outlet 3120 of the atomizing module 3 is connected to the mouthpiece 10, the elastic metal coil 48 is inserted into the first annular groove 15 of the outer shell 1, and the bottom cover 42 of the power supply module 4 is exposed from the opening 11 of the outer shell 1. In other words, the user only needs to pinch the bottom cover 42 to insert and remove the atomizing body 2 to realize the mutual assembly and disassembly between the atomizing body 2 and the outer shell 1, which is very convenient to operate.

[0080] In this embodiment, it is understood that, since the elastic metal coil 48 has a notch 480 and is loosely installed in the second annular groove 4212 (i.e., there is a gap between the elastic metal coil 48 and the inner wall of the second annular groove 4212, so that the elastic metal coil 48 has space to contract when it undergoes elastic deformation due to compression), during the process of inserting the atomizing body 2 into the receiving cavity 12 of the outer shell 1 from the opening 11 of the outer shell 1, when the elastic metal coil 48 is compressed by the inner wall of the outer shell 1, the elastic metal coil 48 will undergo elastic deformation and "retract" into the second annular groove 4212, so that the elastic metal coil 48 will not obstruct the insertion of the atomizing body 2 into the outer shell 1. The atomizing body 2 is inserted into the receiving cavity 12 of the outer shell 1 (so that the atomizing body 2 can be smoothly inserted into the receiving cavity 12 of the outer shell 1); when the atomizing body 2 moves to the position corresponding to the elastic metal coil 48 and the first annular groove 15, the elastic metal coil 48 is reset due to the pressure of the inner wall of the outer shell 1 and springs into the first annular groove 15 and engages with the first annular groove 15, so that the outer shell 1 and the atomizing body 2 can be reliably connected together; when the user pulls the bottom cover 42 with force with his finger, the elastic metal coil 48 will be squeezed by the inner wall of the outer shell 1 and elastically contract and dislodge from the first annular groove 15, so that the user can smoothly pull the atomizing body 2 out of the receiving cavity 12 of the outer shell 1.

[0081] Furthermore, in some optional embodiments of this application, the first connecting structure 1A and the second connecting structure 4A may also have the following structural forms:

[0082] Specifically, please refer to the following: Figure 10-17The inner peripheral wall of the outer shell 1 has a circular cross-section, and the outer peripheral wall of the atomizing body 2 located in the receiving cavity 12 has a circular cross-section. The first connecting structure 1A includes an alignment groove 16 and an arc-shaped limiting groove 17 disposed on the inner peripheral wall of the outer shell 1. The alignment groove 16 extends along the height direction of the outer shell 1, and the arc-shaped limiting groove 17 extends along the circumference of the outer shell 1. One end of the alignment groove 16 along the height direction of the outer shell 1 is connected to one end of the arc-shaped limiting groove 17, and the other end of the alignment groove 16 penetrates the end face of the outer shell 1 away from the nozzle 10. The second connecting structure 4A includes a limiting protrusion 4213 that can slide along the alignment groove 16 and the arc-shaped limiting groove 17 respectively. The limiting protrusion 4213 is disposed on the outer peripheral wall of the power supply module 4 located in the receiving cavity 12, and the limiting protrusion 4213 slides in cooperation with the arc-shaped limiting groove 17.

[0083] In this embodiment, based on the above structural design, when it is necessary to remove the entire atomizing body 2 from the receiving cavity 12 of the outer shell 1, the user can hold the outer shell 1 with one hand and pinch the bottom cover 42 with the other hand, and first apply a circumferential rotational force to the bottom cover 42, so that the limiting protrusion 4213 rotates along the arc-shaped limiting groove 17 to a position aligned with the alignment groove 16 (equivalent to releasing the locking effect between the limiting protrusion 4213 and the arc-shaped limiting groove 17; when the user can clearly feel that he can no longer rotate the bottom cover 42 in the same direction, it indicates that the limiting protrusion 4213 has rotated to a position aligned with the alignment groove 16). Then, a pulling force is applied to the bottom cover 42 in a direction away from the mouthpiece 10, thus removing the entire atomizing body 2. The main body 2 is pulled out from the receiving cavity 12 of the outer shell 1. When it is necessary to assemble the atomizing main body 2 and the outer shell 1 to form a complete atomizing device for use, the limiting protrusion 4213 can be aligned with the alignment groove 16 first, and then the atomizing main body 2 can be inserted into the receiving cavity 12 of the outer shell 1. When the user can clearly feel that he can no longer push the atomizing main body 2, a rotational force along the circumference of the atomizing main body 2 is applied to the bottom cover 42, so that the limiting protrusion 4213 slides into the arc-shaped limiting groove 17 to lock the atomizing main body 2 and the outer shell 1 together. When the user can clearly feel that he can no longer rotate the bottom cover 42 in the same direction, it indicates that the atomizing main body 2 has been installed in place, and at this time the atomizing main body 2 cannot be pulled out from the receiving cavity 12 of the outer shell 1. That is, in the technical solution provided in this embodiment, the user only needs to pinch the bottom cover 42 to rotate and insert the atomizing body 2 to achieve mutual disassembly and assembly between the atomizing body 2 and the outer shell 1, which is relatively convenient to operate.

[0084] Furthermore, in some optional embodiments of this application, when the detachable connection between the outer shell 1 and the atomizing body 2 is a magnetic connection, the structural forms of the first connection structure 1A and the second connection structure 4A can be as follows:

[0085] Specifically, please refer to the following: Figure 10 as well as Figure 23-24 The first connecting structure 1A includes at least two spaced-apart first magnetic elements 5, and the second connecting structure 4A includes at least two spaced-apart second magnetic elements 49. The at least two first magnetic elements 5 and the at least two second magnetic elements 49 attract each other, thereby achieving a detachable connection between the outer shell 1 and the atomizing body 2. In specific implementations, at least one of the first magnetic elements 5 and the second magnetic elements 49 is a magnet. For example, both the first magnetic element 5 and the second magnetic element 49 are magnets. Alternatively, one of the first magnetic elements 5 and the second magnetic element 49 is a magnet, and the other is a magnetic conductor made of a magnetically conductive material (e.g., iron, nickel-chromium-iron alloy, silicon steel, etc.). As long as the usage requirements are met, it is acceptable. This embodiment does not impose specific limitations on the specific structural forms of the first magnetic elements 5 and the second magnetic elements 49.

[0086] In this embodiment, it is understood that the user only needs to pinch the bottom cover 42 to insert and remove the atomizing body 2 to achieve mutual assembly and disassembly between the atomizing body 2 and the outer shell 1, which is very convenient. Specifically, in some optional embodiments, the first magnetic component 5 can be embedded in the inner peripheral wall of the outer shell 1, and correspondingly, the second magnetic component 49 can be embedded in the outer peripheral wall of the power supply module 4; in other optional embodiments, the first magnetic component 5 can also be embedded in the end face of the outer shell 1 away from the nozzle 10, and correspondingly, the second magnetic component 49 can be embedded in the outer wall of the power supply module 4 that contacts the end face of the outer shell 1 away from the nozzle 10. As long as a magnetic connection between the outer shell 1 and the atomizing body 2 can be achieved, this embodiment does not impose specific limitations on the specific placement of the first magnetic component 5 and the second magnetic component 49.

[0087] Furthermore, in some optional embodiments of this application, the atomizing module 3 and the power supply module 4 may be structurally configured as follows:

[0088] Specifically, please refer to Figure 2-3 , Figure 5-6 as well as Figure 8-9 The atomizing module 3 includes a housing assembly 31 and an atomizing core 32. The housing assembly 31 has a first air passage 301 and a storage cavity 302 for storing vapor-forming substances inside. The top of the housing assembly 31 has a mist outlet 3120 that communicates with the first air passage 301. The atomizing core 32 is installed on the airflow path of the first air passage 301 and is connected to the storage cavity 302 so that the atomizing core 32 can draw vapor-forming substances from the storage cavity 302 for heating and atomization to generate vapor. It should be noted that the specific structure and working principle of the atomizing core 32 are well known to those skilled in the art and will not be described in detail here.

[0089] The power supply module 4 includes a main housing 41, an electrode assembly 43, a battery 44, and a control circuit board 45. The top of the main housing 41 has a receiving groove 411. The electrode assembly 43 protrudes from the bottom wall of the receiving groove 411 and can be electrically connected to the control circuit board 45 via wires or other means. The bottom of the housing assembly 31 is detachably installed in the receiving groove 411, and the electrode assembly 43 is electrically connected to the atomizing core 32. The battery 44 is installed inside the main housing 41 and is electrically connected to the control circuit board 45. A second air passage 412 is formed between the battery 44 and the inner wall of the main housing 41, and the second air passage 412 is connected to the first air passage 301; the bottom cover 42 is fixedly fitted onto the bottom outer wall of the main housing 41 (the connection between the bottom cover 42 and the main housing 41 can be a snap-fit ​​connection or an interference fit), and the bottom cover 42 abuts against the end face of the outer housing 1 away from the nozzle 10; the second connection structure 4A is disposed on the outer wall of the bottom cover 42 or the outer wall of the main housing 41 (exemplarily, such as...). Figure 2-3 As shown, the second connecting structure 4A is disposed on the outer wall of the bottom cover 42. An air inlet 4221 communicating with the second air passage 412 is provided on the bottom surface of the bottom cover 42. The control circuit board 45 is installed inside the bottom cover 42, and the control circuit board 45 is equipped with a microphone sensor 46 for detecting changes in airflow in the second air passage 412.

[0090] In this embodiment, based on the above structural design, the operating principle of the vapor generation device provided in this embodiment is as follows:

[0091] When a user bites the mouthpiece 10 and inhales, a suction airflow is formed along the path that connects the air inlet 4221, the second airway 412, the first airway 301, the mist outlet 3120, and the mouthpiece 10. This suction airflow triggers the microphone sensor 46 to send a suction signal to the control circuit board 45 to indicate that the user is inhaling. When the control circuit board 45 receives the suction signal, it connects the battery 44 and the electrode assembly 43, causing the atomizing core 32 to be energized and heated, and atomizing the vapor-forming substance it adsorbs into vapor. When the suction airflow passes through the atomizing core 32, the vapor produced by the atomizing core 32 is carried away by the suction airflow and finally discharged to the mouthpiece 10 for the user to inhale. When the user stops inhaling, the airflow disappears, triggering the microphone sensor 46 to send a stop signal to the control circuit board 45, indicating that the user has stopped inhaling. Upon receiving this stop signal, the control circuit board 45 disconnects the electrical connection between the battery 44 and the electrode assembly 43, thereby de-energizing the atomizing core 32 and stopping its operation. This enhances the intelligence of the atomizing device, thus improving the user experience.

[0092] In this embodiment, it should be noted that the electrical connection between the electrode assembly 43 and the atomizing core 32 can be direct or indirect. This embodiment does not impose specific limitations on this. When the electrical connection between the electrode assembly 43 and the atomizing core 32 is indirect, the electrode assembly 43 can be a conductive spring pin. At the same time, a conductive pin that presses against the electrode leads of the atomizing core 32 can be provided on the bottom surface of the housing assembly 31. After the bottom of the housing assembly 31 is installed in the receiving groove 411 of the main housing 41, the conductive pin and the conductive spring pin make electrical contact.

[0093] In this embodiment, it should also be noted that, in specific implementation, the control circuit board 45 can be a microcontroller, processor, controller, or other mature devices with control functions in the art. Furthermore, the detachable connection between the bottom of the housing assembly 31 and the main housing 41 can be a threaded connection, a snap-fit ​​connection, a magnetic connection, a plug-in connection, etc.

[0094] Furthermore, in some optional embodiments of this application, the specific structural composition of the atomizing module 3 and the electrical connection between the electrode assembly 43 and the atomizing core 32 can be as follows:

[0095] Specifically, please refer to the following: Figure 3 , Figure 5-6 as well as Figure 8-9 The nozzle 10 has an internal pipe section 101 with a suction channel 102. The housing assembly 31 includes a cup body 311, a top cover 312, a base 313, and an air duct 314 with an atomization channel 3140. The top cover 312 fits into the upper port of the cup body 311. The top cover 312 is hollow and has a mist outlet 3120 on its upper surface. The mist outlet 3120 is a stepped hole. The lower end of the pipe section 101 is inserted into the mist outlet 3120 and forms a plug-in connection with the top cover 312. One end of the base 313 is fixedly fitted (e.g., with an interference fit) into the lower port of the cup body 311 along its height direction, and the other end... The end of the cup body 314 is fitted into the receiving groove 411 and forms a plug-in connection with the main housing 41; one end of the air passage tube 314 is fitted with the top cover 312 and the other end is fitted with the base 313. The cup body 311, the top cover 312, the air passage tube 314 and the base 313 together enclose the storage cavity 302. At least one liquid outlet hole 3141 communicating with the storage cavity 302 is opened on the side wall of the air passage tube 314. The atomizing core 32 is hollow and through. The atomizing core 32 is installed in the air passage tube 314 and the outer peripheral wall of the atomizing core 32 covers each liquid outlet hole 3141 (that is, the atomizing core 32 is connected to the storage cavity 302 through the liquid outlet hole 3141).

[0096] The base 313 is provided with an air intake channel 3130. One end of the atomizing channel 3140 is connected to the suction channel 102 and the other end is connected to the air intake channel 3130. The air intake channel 3130 and the atomizing channel 3140 are connected to form at least a portion of the first air passage 301. The bottom wall of the receiving groove 411 is provided with at least one vent hole 413 connected to the second air passage 412. The second air passage 412 is connected to the air intake channel 3130 through at least one vent hole 413. Specifically, the air intake channel 3130 has at least one air intake port located on the bottom surface of the base 313. Each air intake port is connected to each vent hole 413 in a one-to-one correspondence.

[0097] The atomizing core 32 has a first electrode lead 321 and a second electrode lead 322. The base 313 also has a first electrode insertion hole 3131 and a second electrode insertion hole 3132. The electrode assembly 43 includes a first electrode post 431 and a second electrode post 432. One end of the first electrode lead 321 extends into the first electrode insertion hole 3131, and one end of the second electrode lead 322 extends into the second electrode insertion hole 3132. The first electrode post 431 is inserted into the first electrode insertion hole 3131 and forms a plug-in connection with the base 313. The second electrode post 432 is inserted into the second electrode insertion hole 3132 and forms a plug-in connection with the base 313. The first electrode post 431 is in electrical contact with the first electrode lead 321, and the second electrode post 432 is in electrical contact with the second electrode lead 322.

[0098] In the technical solution provided in this embodiment, on the one hand, the detachable connection between the atomizing module 3 and the power supply module 4 is achieved by using the plug-in connection between the two electrode posts and the base 313. Compared with the detachable connection between the atomizing module 3 and the power supply module 4 by magnetic attraction, the setting of magnetic components can be eliminated (for example, there is no need to set magnets on the bottom wall of the receiving groove 411 and the bottom surface of the base 313), which helps to reduce the production cost of the vapor generating device. On the other hand, when the electrode posts are inserted into the base 313, they will form electrical contact with the electrode pins of the atomizing core 32, thereby realizing the direct electrical connection between the electrode assembly 43 and the atomizing core 32. Compared with the electrical connection method of setting conductive pins on the bottom surface of the base 313 and setting the structure of the electrode assembly 43 as conductive spring pins, this electrical connection method saves conductive pins and the part cost of the electrode posts is lower than that of conductive spring pins, which helps to further reduce the production cost of the vapor generating device.

[0099] Furthermore, please refer to the following: Figure 2-3 , Figure 6 as well as Figure 8-9In some optional embodiments of this application, the top cover 312 is made of an elastic sealing material, the lower end of the pipe portion 101 is fitted into the mist outlet 3120 with a gap, and the lower end face of the pipe portion 101 abuts against the bottom wall of the mist outlet 3120, thereby enabling the mist outlet 3120 and the suction channel 102 of the nozzle 10 to achieve sealed communication; the base 313 includes a first seat 3133 made of elastic sealing material and a second seat 3134 made of hard plastic, the first seat 3133 and the second seat 3134 are inserted into each other to form a whole, the first seat 3133 and the second seat 3134 each have a portion of a first electrode insertion hole 3131, a portion of a second electrode insertion hole 3132 and a portion of an air inlet channel 3130, the first electrode... One end of the electrode lead 321 extends into a portion of the first electrode insertion hole 3131 located in the first base 3133, and one end of the second electrode lead 322 extends into a portion of the second electrode insertion hole 3132 located in the first base 3133. The first base 3133 is fixedly fitted into the cup body 311. The end of the second base 3134 facing away from the first base 3133 is inserted into the receiving groove 411. At least one sealing ring 34 is sleeved on the outer peripheral wall of the second base 3134. At least one sealing ring 34 is in contact with the inner peripheral wall of the receiving groove 411. The elastic sealing material can be silicone, rubber, silicone rubber, etc., and the rigid plastic can be polycarbonate, polyoxymethylene, polypropylene, polyetherimide, ABS plastic, PCTG plastic, etc.

[0100] In this embodiment, based on the above structural design, on the one hand, since the first base 3133 is made of elastic sealing material, and the electrode leads of the atomizing core 32 extend into a portion of the electrode insertion hole located in the first base 3133, when the two electrode posts are inserted into the base 313, the first base 3133 can tightly wrap around the two electrode posts and allow the two electrode posts to press against the two electrode leads of the atomizing core 32, thereby improving the connection stability between the base 313 and the main housing 41 and the reliability of the electrical connection between the electrode assembly 43 and the atomizing core 32; on the other hand, by using the second A sealing ring 34 is fitted on the outer peripheral wall of the lower end of the base 3134, which can further improve the connection stability between the base 313 and the main housing 41. At the same time, by fitting the lower end of the pipe 101 into the mist outlet 3120, it can be ensured that the connection force between the nozzle 10 and the atomizing module 3 is less than the connection force between the atomizing module 3 and the power supply module 4. This ensures that the entire atomizing body 2 can be smoothly pulled out of the housing cavity 12 of the outer housing 1 during the replacement of the atomizing module 3, avoiding the situation where the power supply module 4 is pulled out while the atomizing module 3 remains in the housing cavity 12.

[0101] Furthermore, in some optional embodiments of this application, the bottom cover 42 may have the following structural form:

[0102] Specifically, please refer to Figure 2 , Figure 5 , Figure 7 as well as Figure 11-15 The bottom cover 42 includes a coaxially arranged cylindrical portion 421 and a lower cover portion 422. The cylindrical portion 421 and the lower cover portion 422 are connected to each other as a whole, and the outer diameter of the cylindrical portion 421 is smaller than the outer diameter of the lower cover portion 422. The cylindrical portion 421 fits into the end of the outer shell 1 away from the mouthpiece 10. A first connecting structure 1A is provided on the inner wall of the end of the outer shell 1 away from the mouthpiece 10, and a second connecting structure 4A is provided on the outer peripheral wall of the cylindrical portion 421. The upper end face of the bottom cover 42 abuts against the end face of the outer shell 1 away from the mouthpiece 10. This arrangement ensures that after the atomizing body 2 is installed into the receiving cavity 12 of the outer shell 1, the lower cover portion 422 of the bottom cover 42 can be exposed from the opening 11 of the outer shell 1, so that the user can disassemble the entire atomizing body 2 through the lower cover portion 422.

[0103] Further, please refer to Figure 10-13 In some optional embodiments of this application, both the outer shell 1 and the cup 311 are made of transparent material, such as glass, acrylic, polycarbonate, etc. This arrangement allows the user to easily observe the remaining amount of vapor-forming material in the storage cavity 302, thus visually determining whether the vapor-forming material in the storage cavity 302 has been completely consumed.

[0104] Further, please refer to Figure 5 In some optional embodiments of this application, the base 313 is provided with a liquid absorber 33 made of porous material inside, which is positioned directly opposite the lower port of the airway tube 314. The porous material can be fiber cotton, sponge, etc. With this configuration, when liquid vapor-forming material (such as e-liquid) leaks from the liquid outlet 3141 of the airway tube 314, the liquid absorber 33 can absorb the liquid vapor-forming material dripping from the lower port of the airway tube 314, thereby making it difficult for the liquid vapor-forming material to leak from the air inlet port of the air inlet channel 3130. This effectively prevents the liquid vapor-forming material from flowing onto the battery 44 or the control circuit board 45 and causing damage to the battery 44 or the control circuit board 45.

[0105] Further, please refer to Figure 1 as well as Figure 5-6In some optional embodiments of this application, the bottom surface of the bottom cover 42 is further provided with an inlet 4222 spaced apart from the air inlet 4221, and the control circuit board 45 is also equipped with a charging interface 47 corresponding to the inlet 4222. This arrangement allows the user to easily charge the battery 44 when its power is low or depleted, thereby extending the lifespan of the power supply module 4 and enabling it to be used repeatedly. In specific implementations, the charging interface 47 can be a USB interface or a Type-C interface; this embodiment does not impose specific limitations on this.

[0106] Further, please refer to Figure 6 In some optional embodiments of this application, the atomizing module 3 further includes a liquid storage 35 made of a porous material, which is disposed within the storage cavity 302. The porous material can be fiber cotton, sponge, etc. This arrangement allows the liquid storage 35 to adsorb the liquid vapor-forming substance within the storage cavity 302, making it less likely for the liquid vapor-forming substance to leak from the liquid outlet 3141.

[0107] Further, please refer to Figure 1-2 , Figure 5 as well as Figure 10-13 In some optional embodiments of this application, the outer peripheral wall of the bottom cover 42 is provided with exposed anti-slip texture 4220. The structure of the anti-slip texture 4220 can be a groove or a protrusion, as long as it meets the usage requirements. This embodiment does not impose specific limitations on the structure of the anti-slip texture 4220. With this design, the anti-slip texture 4220 can increase the friction between the user's fingers and the bottom cover 42, thereby preventing slippage between the user's fingers and the bottom cover 42 when the user pinches the bottom cover 42 and applies force to insert, remove, or rotate the atomizing body 2, thus avoiding affecting the smoothness of disassembling and assembling the atomizing body 2.

[0108] 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.

[0109] 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.
