Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to a power supply component and an electronic atomization device. Background Technology

[0002] Electronic atomizing devices are electronic devices that can vaporize stored e-liquids, medicines, or other atomizing liquids into vapor through electric heating. Among them, refillable vapor generators are a relatively common type of electronic atomizing device on the market.

[0003] Replaceable atomizers typically include detachable atomizers and a power supply unit. The atomizer generally has a reservoir for storing the atomizing liquid, an atomizing core for absorbing the liquid and atomizing it into vapor, an atomization channel for expelling the vapor, and an air inlet for allowing outside air to enter the atomization channel. The power supply unit generally has a housing for the atomizer, a battery for powering the atomizing core, and a control circuit board for controlling the atomizing core's operating state. In use, the atomizer is inserted into the housing of the power supply unit, establishing an electrical connection between the atomizing core and the battery. When the user triggers the control circuit board to supply power to the atomizing core, the core heats up and atomizes the absorbed liquid into vapor for the user to inhale. When the user inhales, outside air enters the atomization channel through the air inlet, carrying the vapor produced by the atomizing core out of the atomization channel for the user to inhale.

[0004] However, the replaceable aerosol generators currently on the market generally have the following problems:

[0005] During the user's vaping process, some vapor will remain in the atomization channel and condense to form condensate. Under its own gravity, this condensate can easily leak through the air inlet at the bottom of the atomizer into the power unit's containment chamber and gradually seep into the power unit's interior. Once the condensate comes into contact with the control circuit board or battery in the power unit, it may cause the control circuit board or battery to be damaged due to short circuit or corrosion by the condensate. Utility Model Content

[0006] The main objective of this application is to provide a power supply component and an electronic atomizing device, which aims to solve the technical problem that the control circuit board or battery in the power supply component is easily damaged due to condensate leakage from the atomizer in the prior art.

[0007] To achieve the above objectives, in a first aspect, this application provides a power supply assembly for detachably assembling and using with an atomizer. The atomizer has a liquid reservoir, an atomization channel, and an atomizing core inside. An air inlet is provided on the bottom surface of the atomizer. The atomization channel communicates with the air inlet. The atomizing core is installed within the atomization channel and communicates with the liquid reservoir. The power supply assembly includes:

One end of the pipe section is connected to the air intake hole. The main housing has an installation space that is separated from the air intake.

[0009] A sealing element is fitted onto the end of the pipe section opposite to the air inlet. The side of the sealing element opposite to the air inlet has a groove.

[0024] To achieve the above objectives, in a second aspect, this application also provides an electronic atomizing device, which includes an atomizer and a power supply component as described in any of the above embodiments.

[0026] Compared with the prior art, this application has at least the following beneficial effects:

[0027] In the technical solution of this application, the main housing of the power assembly is provided with a receiving cavity for accommodating the atomizer and a pipe section with an air intake. One end of the pipe section is connected to the air intake hole located at the bottom of the main housing, and the other end of the pipe section is fitted with a sealing member. The side of the sealing member facing away from the air intake hole is provided with a groove connected to the receiving cavity. The bottom wall of the groove is provided with a vent hole connected to the other end of the pipe section. The interior of the main housing is provided with an installation space separated from the air intake. The battery is installed in the installation space, and the control circuit board is fitted on the outer wall of the pipe section. When the bottom of the atomizer is inserted into the receiving cavity of the main housing, the sealing member contacts the bottom surface of the atomizer, and the groove is connected to the air intake hole located on the bottom surface of the atomizer. In this way, when condensate leaks from the atomizer, the condensate leaking from the air inlet on the bottom of the atomizer will only fall into the groove of the seal, and will not drip onto the bottom wall of the receiving cavity. Moreover, the condensate falling into the groove can be discharged to the external environment outside the power assembly through the vent, air inlet and air outlet. The condensate is unlikely to come into contact with the battery located in the installation space and the control circuit board sleeved on the outer wall of the pipe section, thereby effectively reducing the risk of damage to the control circuit board and battery due to contact with condensate.

[0044] 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

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] Please refer to the reference. Figure 1-5 and Figure 8-11 This application provides a power supply assembly 1, which is used to detachably assemble with an atomizer 2 to form an electronic atomizing device. The atomizer 2 has a liquid storage chamber 202, an atomization channel 201, and an atomizing core 22 inside. The bottom surface of the atomizer 2 has an air inlet 2410, and the atomization channel 201 communicates with the air inlet 2410. The atomizing core 22 is installed in the atomization channel 201 and communicates with the liquid storage chamber 202. The power supply assembly 1 includes a main housing 11, a sealing member 12, a first electrode assembly 13, a control circuit board 14, and a battery 15, wherein:

[0051] The main housing 11 has a receiving cavity 110 for accommodating at least part of the atomizer 2 and a pipe section 111 with an air inlet 1110. An air inlet 112 is provided at the bottom of the main housing 11. One end port of the pipe section 111 (specifically, the lower port of the pipe section 111) is correspondingly connected to the air inlet 112. The main housing 11 also has an installation space 113 separated from the air inlet 1110. It should be noted that, in specific implementations, the lower port of the pipe section 111 can be directly or indirectly connected to the air inlet 112, as long as the condensate flowing from the lower port of the pipe section 111 can be discharged through the air inlet 112 to the external environment outside the power supply assembly 1. This embodiment does not impose specific limitations on the specific connection method between the lower port of the pipe section 111 and the air inlet 112. For example, as... Figure 3 As shown, in some optional embodiments, the lower end of the pipe section 111 extends into the air inlet 112, thereby allowing the lower port of the pipe section 111 to directly communicate with the air inlet 112; for example, as... Figure 7 As shown, in some alternative embodiments, a hollow, through-hole second sealing sleeve 18 is fitted onto the lower end of the pipe section 111. The lower end of the second sealing sleeve 18 abuts against the part of the main housing 11 where the air inlet 112 is provided, and the lower port of the second sealing sleeve 18 is positioned directly opposite the air inlet 112, so that the lower port of the pipe section 111 can be indirectly connected to the air inlet 112.

[0052] The sealing element 12 is fitted onto the end of the pipe section 111 opposite to the air inlet 112 (i.e., the sealing element 12 is fitted onto the upper end of the pipe section 111). A groove 120 is provided on the side of the sealing element 12 opposite to the air inlet 112. The portion of the sealing element 12 with the groove 120 is exposed on the bottom wall of the receiving cavity 110, and the groove 120 of the sealing element 12 communicates with the receiving cavity 110 of the main housing 11. A vent hole 1210 is provided on the bottom wall of the groove 120, and this vent hole 1210 is correspondingly connected to the end of the pipe section 111 opposite to the air inlet 112. It should be noted that, in specific implementations, the sealing element 12 can be made of materials with good sealing performance, such as silicone, rubber, or silicone rubber.

[0053] The first electrode assembly 13 is exposed on the bottom wall of the receiving cavity 110.

[0054] The control circuit board 14 is sleeved on the outer wall of the pipe section 111, and is electrically connected to the first electrode assembly 13. It should be noted that, in specific implementations, the control circuit board 14 can be directly sleeved on the outer wall of the pipe section 111, or indirectly sleeved on the outer wall of the pipe section 111, as long as it ensures that the condensate flowing from the lower port of the pipe section 111 does not drip onto the control circuit board 14. This embodiment does not impose specific limitations in this regard. For example, as... Figure 3 , Figure 5 and Figure 7 As shown, the control circuit board 14 is indirectly fitted onto the outer wall of the pipe section 111 through the second sealing sleeve 18. That is, the outer wall of the pipe section 111 is fitted with the second sealing sleeve 18, which can be made of silicone, and the control circuit board 14 is fitted onto the outer wall of the second sealing sleeve 18.

[0055] The battery 15 is installed in the mounting space 113 of the main unit housing 11, and the battery 15 is electrically connected to the control circuit board 14.

[0056] like Figure 3 and Figure 8-12As shown, when the bottom of the atomizer 2 is inserted into the receiving cavity 110 of the main housing 11, the first electrode assembly 13 is electrically connected to the atomizing core 22, the sealing member 12 is in contact with the bottom surface of the atomizer 2, and the groove 120 is connected to the air inlet 2410.

[0057] In this embodiment, based on the above structural design, when the atomizer 2 leaks condensate, the condensate leaking from the air inlet 2410 located on the bottom surface of the atomizer 2 will only fall into the groove 120 of the seal 12, and will not drip onto the bottom wall of the receiving cavity 110. Moreover, the condensate falling into the groove 120 can be discharged to the external environment outside the power assembly 1 through the vent 1210, the air inlet 1110 and the air inlet 112 in sequence. The condensate is unlikely to come into contact with the battery 15 located in the installation space 113 and the control circuit board 14 sleeved on the outer wall of the pipe section 111, thereby effectively reducing the risk of damage to the control circuit board 14 and the battery 15 due to contact with condensate.

[0058] Further, please refer to Figure 2-4 and Figure 10-11 In some optional embodiments of this application, a first protrusion 121 protrudes from the bottom wall of the groove 120. The first protrusion 121 is hollow and has a through-hole vent 1210. Along the height direction of the main housing 11, the protrusion height of the first protrusion 121 is less than the depth of the groove 120. Figure 4As shown, assuming the protrusion height of the first protrusion 121 is H1 and the depth of the groove 120 is H0, then H1 < H0. When the bottom of the atomizer 2 is inserted into the receiving cavity 110, the first protrusion 121 and the air inlet 2410 are offset from each other. This can be understood as follows: assuming the vertical projection of the air inlet 2410 onto the bottom wall of the groove 120 is a first circle, and the vertical projection of the upper end of the first protrusion 121 onto the bottom wall of the groove 120 is a second circle, then the first circle and the second circle do not overlap. This design ensures that, when condensate leaks from the atomizer 2, the condensate leaking from the air inlet 2410 on the bottom surface of the atomizer 2, after falling into the groove 120 of the seal 12, will not immediately flow into the air inlet 1110 of the pipe section 111 through the vent 1210. Instead, it will first drip onto the bottom wall of the groove 120 and accumulate until the condensate accumulates to the point of overflowing the first protrusion 121 before flowing into the air inlet 1110 of the pipe section 111 through the vent 1210. This delays the discharge of condensate from the air inlet 112. To minimize the time required for condensation to reach the external environment, the condensate should be prevented from being quickly discharged from the exhaust port into the external environment, thus affecting the user experience. On the other hand, since the atomizer 2 can be disassembled relative to the power assembly 1, even if condensate accumulates in the groove 120, the user can clean the condensate in the groove 120 after removing the atomizer 2 from the receiving chamber 110 of the power assembly 1 (for example, by absorbing the condensate in the groove 120 with a tissue or cotton swab), so as to ensure the cleanliness of the power assembly 1 and prevent excessive discharge of condensate into the external environment, which would cause pollution to the external environment.

[0059] In this embodiment, it should be noted that, in specific implementation, in order to ensure that after the bottom of the atomizer 2 is inserted into the receiving cavity 110 of the main housing 11, a sufficient air gap can be formed between the bottom surface of the atomizer 2 and the upper end surface of the first protrusion 121, so as to ensure that a smooth suction airflow can be formed on the path that connects the air inlet 112, the air inlet channel 1110, the air vent 1210, the groove 120, the air inlet 2410, and the atomization channel 201 in sequence, during the user's use of the electronic atomizing device for inhalation, the difference between the depth of the groove 120 and the protrusion height of the first protrusion 121 can be set to 0.5 to 3 mm, that is, 0.5 mm ≤ H0 - H1 ≤ 3 mm.

[0060] Furthermore, in some optional embodiments of this application, in order to improve the "liquid storage" capacity of the groove 120 and better delay the time for condensate to be discharged from the air inlet 112 to the external environment, the dimensions of the groove 120 and the height of the first protrusion 121 can be set as follows:

[0061] Specifically, such as Figure 2 and Figure 4As shown, along the first direction of the main unit housing 11 (exemplarily, the first direction of the main unit housing 11 is...) Figure 2 The length L of the groove 120 is 4-10 mm (in the left-right direction); along the second direction of the main housing 11 (exemplarily, the second direction of the main housing 11 is...). Figure 2 In the front-to-back direction), the width W of the groove 120 is 4 to 10 mm; along the height direction of the main housing 11, the depth H0 of the groove 120 is 1 to 4 mm, the protrusion height H1 of the first protrusion 121 is 0.5 to 3 mm, and the first direction, the second direction, and the height direction of the main housing 11 are perpendicular to each other.

[0062] For example, the length L of the groove 120 can be set to 4mm, the width W of the groove 120 can be set to 4mm, the depth H0 of the groove 120 can be set to 1mm, and the height of the first protrusion 121 can be set to 0.5mm.

[0063] For example, the length L of the groove 120 can be set to 8mm, the width W of the groove 120 can be set to 7mm, the depth H0 of the groove 120 can be set to 2mm, and the height of the first protrusion 121 can be set to 1mm.

[0064] For example, the length L of the groove 120 can be set to 10mm, the width W of the groove 120 to 10mm, the depth H0 of the groove 120 to 4mm, and the height of the first protrusion 121 to 3mm. And so on.

[0065] Further, please refer to Figure 3-5 and Figure 10-11In some optional embodiments of this application, a microphone sensor 16 electrically connected to the control circuit board 14 is installed on the side of the control circuit board 14 facing away from the air inlet 112. The main housing 11 is also provided with a microphone air passage 114 separated from the air inlet 1110. The power supply assembly 1 also includes a first sealing sleeve 17. The material of the first sealing sleeve 17 can be silicone, rubber, silicone rubber, or other materials with good sealing performance. The first sealing sleeve 17 is sealed and fitted (specifically, it can be an interference fit) in one end of the microphone air passage 114 and encloses the microphone sensor 16. The end face of the first sealing sleeve 17 facing away from the control circuit board 14 is provided with a microphone through hole 1710, which is connected to the microphone air passage 114 and the inner cavity of the first sealing sleeve 17. A second protrusion is also provided on the bottom wall of the groove 120. Part 122, the second protrusion 122 is hollow and has a through-hole forming a sensing air hole 1220. The sensing air hole 1220 is connected to the end port of the microphone air passage 114 away from the first sealing sleeve 17. Along the height direction of the main body shell 11, the protrusion height H2 of the second protrusion 122 is greater than the protrusion height H1 of the first protrusion 121 and less than the depth H0 of the groove 120, that is, H1 < H2 < H0. When the bottom of the atomizer 2 is inserted into the receiving cavity 110, the second protrusion 122 and the air inlet 2410 are offset from each other. It can be understood that, assuming that the vertical projection of the air inlet 2410 on the bottom wall of the groove 120 is a first circle, and the vertical projection of the upper end of the second protrusion 122 on the bottom wall of the groove 120 is a third circle, then the first circle and the third circle do not overlap.

[0066] In this embodiment, based on the above structural design, the intelligence level of the electronic atomizing device can be improved while effectively reducing the risk of damage to the microphone sensor 16 due to contact with condensate. Specifically, during the user's use of the electronic atomizing device for vaping, a suction airflow is formed along the path that sequentially connects the air inlet 112, air inlet channel 1110, vent 1210, groove 120, air inlet 2410, and atomization channel 201. When the suction airflow flows through the groove 120, a negative pressure is formed at the upper port of the second protrusion 122. This negative pressure triggers the microphone sensor 16 to send a suction signal to the control circuit board 14 to indicate that the user is vaping. When the control circuit board 14 receives the suction signal, it controls the battery 1... 5 provides electrical energy to the atomizing core 22, enabling the atomizing core 22 to perform atomization. When the user stops inhaling, the inhalation airflow disappears, causing the negative pressure formed at the upper port of the second protrusion 122 to disappear. This triggers the microphone sensor 16 to send a stop signal to the control circuit board 14 to indicate that the user has stopped inhaling. When the control circuit board 14 receives the stop signal, it controls the battery 15 to stop providing electrical energy to the atomizing core 22, thereby de-energizing the atomizing core 22 and stopping its operation. This improves the intelligence of the electronic atomizing device.

[0067] Since both the first protrusion 121 and the second protrusion 122 are offset from the air inlet 2410 of the atomizer 2, when condensate leaks from the atomizer 2, the condensate leaking from the air inlet 2410 located on the bottom surface of the atomizer 2 falls into the groove 120 of the seal 12 and accumulates on the bottom wall of the groove 120. Simultaneously, because the protrusion height H2 of the second protrusion 122 is greater than the protrusion height H1 of the first protrusion 121, the condensate will only accumulate to the point of overflowing the first protrusion 121, and will not accumulate further. When the condensate accumulates to the point of overflowing the second protrusion 122, and when the condensate accumulates to the point of overflowing the first protrusion 121, the condensate will flow from the vent 1210 into the air inlet 1110 of the pipe section 111 and be discharged to the external environment through the air inlet 112. This makes it difficult for the condensate accumulated in the groove 120 to pass through the upper port of the second protrusion 122, the microphone airway 114, and the microphone through hole 1710 in sequence to contact the microphone sensor 16, thereby effectively reducing the risk of damage to the microphone sensor 16 due to contact with the condensate.

[0068] In this embodiment, it should be noted that, in order to ensure that after the bottom of the atomizer 2 is inserted into the receiving cavity 110 of the main housing 11, a sufficient gap can be formed between the bottom surface of the atomizer 2 and the upper end surface of the second protrusion 122 to improve the sensitivity of the microphone sensor 16 in detecting negative pressure, the difference between the depth H0 of the groove 120 and the protrusion height H2 of the second protrusion 122 can be set to 0.3 to 2.5 mm, that is, 0.3 mm ≤ H0 - H2 ≤ 2.5 mm.

[0069] Furthermore, in order to prevent the condensate accumulated in the groove 120 from entering the microphone air passage 114 through the upper port of the second protrusion 122 when the electronic atomizing device is tilted, and to further reduce the risk of damage to the microphone sensor 16 due to contact with the condensate, the difference between the protrusion height H2 of the second protrusion 122 and the protrusion height H1 of the first protrusion 121 can be set to 0.4 to 2 mm, that is, 0.4 mm ≤ H2 - H1 ≤ 2 mm.

[0070] Further, please refer to Figure 5 In some optional embodiments of this application, a third protrusion 171 protrudes from one end face of the first sealing sleeve 17 facing away from the control circuit board 14. The third protrusion 171 is hollow and has a through-hole 1710 for forming a microphone through-hole. The third protrusion 171 is offset from the end port of the microphone air passage 114 near the sensing air hole 1220. With this configuration, even if condensate enters the microphone air passage 114 through the upper port of the second protrusion 122, the condensate cannot immediately contact the microphone sensor 16. Instead, it accumulates on the upper surface of the first sealing sleeve 17. Only when the condensate dripping onto the upper surface of the first sealing sleeve 17 accumulates to the point of overflowing the third protrusion 171 can the condensate possibly contact the microphone sensor 16. This further reduces the risk of damage to the microphone sensor 16 due to contact with condensate. In specific implementation, in order to prevent the condensate from flowing into the inner cavity of the first sealing sleeve 17 through the upper port of the third protrusion 171 and contacting the microphone sensor 16, and at the same time to ensure the detection sensitivity of the microphone sensor 16, the protrusion height of the third protrusion 171 along the height direction of the main housing 11 can be set to 0.5 to 5 mm.

[0071] Further, please refer to Figure 1 , Figure 3 and Figure 6In some optional embodiments of this application, the power supply assembly 1 further includes a pin 19, the main housing 11 includes an inner housing 11A and an outer housing 11B, the inner housing 11A has a receiving cavity 110, a pipe section 111 and an installation space 113, the top of the outer housing 11B has an opening 115, the interior of the outer housing 11B has a receiving cavity 116, the bottom of the outer housing 11B has an air inlet 112, at least a portion of the inner housing 11A is inserted into the receiving cavity 116 and the receiving cavity 110 is located at the opening 115, and a first mounting hole 117 is formed on the side wall of the inner housing 11A. The outer casing 11B has a second mounting hole 118 on its side wall, corresponding to the first mounting hole 117. One end of the pin 19 is interference-fitted with the first mounting hole 117, and the other end is fitted with the second mounting hole 118. The inner casing 11A has a detachment space 119 corresponding to the first mounting hole 117. When the end of the pin 19 fitted with the second mounting hole 118 is impacted by an external force, the pin 19 can disengage from the first mounting hole 117 and enter the detachment space 119, allowing the inner casing 11A and the outer casing 11B to be detached. This design facilitates disassembly and maintenance of the power supply assembly 1 when it malfunctions. Specifically, when the power supply assembly 1 malfunctions, the maintenance personnel can first use tools to tap the pin 19 from the outside of the outer casing 11B, causing the pin 19 to disengage from the first mounting hole 117 of the inner casing 11A and enter the detachment space 119 of the inner casing 11A. Then, force is applied to pull the entire inner casing 11A out from the opening 115 of the outer casing 11B. Subsequently, the relevant components in the inner casing 11A can be inspected and repaired. In practice, the number and installation position of the pins 19 can be flexibly set according to actual needs. For example, such as... Figure 3 and Figure 6 As shown, there are two pins 19, which are located on opposite sides of the power supply assembly 1 and have a height difference between them along the height direction of the main housing 11.

[0072] Correspondingly, please refer to Figure 8-10 This application also provides an electronic atomizing device, which includes an atomizer 2 (such as...). Figure 11-12 (as shown) and the power supply component 1 mentioned in any of the above embodiments (such as Figure 1-7As shown, the top of the atomizer 2 is provided with a mouthpiece 25 for the user to inhale. The interior of the atomizer 2 is provided with a liquid storage chamber 202, an atomization channel 201 and an atomizing core 22. The bottom surface of the atomizer 2 is provided with an air inlet 2410. One end of the atomization channel 201 is connected to the mouthpiece 25 and the other end is connected to the air inlet 2410. The atomizing core 22 is installed in the atomization channel 201 and is connected to the liquid storage chamber 202. The bottom of the atomizer 2 is detachably inserted into the receiving cavity 110, and the atomizing core 22 is electrically connected to the first electrode assembly 13. The sealing member 12 is in contact with the bottom surface of the atomizer 2, and the groove 120 is correspondingly connected to the air inlet 2410.

[0073] In this embodiment, it should be noted that, in specific implementation, the detachable connection between the atomizer 2 and the main housing 11 can be a magnetic connection, a plug-in connection, a snap-fit ​​connection, etc., and this embodiment does not impose specific limitations on this. Furthermore, the electrical connection between the atomizing core 22 and the first electrode assembly 13 can be a direct electrical connection or an indirect electrical connection. This embodiment does not impose specific limitations on the specific electrical connection method between the atomizing core 22 and the first electrode assembly 13. Specifically, when the electrical connection between the atomizing core 22 and the first electrode assembly 13 is a direct electrical connection, the structure of the first electrode assembly 13 can be a metal conductive post. When the bottom of the atomizer 2 is inserted into the receiving cavity 110 of the main housing 11, the upper end of the metal conductive post can be inserted into the bottom of the atomizer 2 and contact the electrode pins of the atomizing core 22. When the electrical connection between the atomizing core 22 and the first electrode assembly 13 is an indirect electrical connection, such as... Figure 2-3 and Figure 11 As shown, the first electrode assembly 13 can be a conductive spring needle. Meanwhile, a second electrode assembly 23 can be exposed at the bottom of the atomizer 2. The second electrode assembly 23 can be a conductive pin that is pressed against the electrode leads of the atomizing core 22. When the bottom of the atomizer 2 is inserted into the receiving cavity 110 of the main housing 11, the conductive spring needle and the conductive pin make elastic contact.

[0074] In this embodiment, it should also be noted that, thanks to the improvement of the power supply component 1, the electronic atomizing device provided in this embodiment has the same technical effect as the power supply component 1, which will not be repeated here.

[0075] Further, please refer to Figure 10-12In some optional embodiments of this application, the atomizer 2 includes a housing 21, a base 24, and an atomizing core 22. The housing 21 has a separately arranged atomizing channel 201 and a liquid storage chamber 202 inside. A mouthpiece 25 is provided at the top of the housing 21 and communicates with the upper port of the atomizing channel 201. The base 24 is installed at the bottom of the housing 21. The base 24 has a receiving groove 242 and an air inlet channel 241 inside. The air inlet channel 241 extends along the height direction of the base 24 and communicates with the lower port of the atomizing channel 201. The lower end of channel 241 is an air inlet 2410, which is located on the bottom surface of base 24. The receiving groove 242 is located below the liquid storage chamber 202, and the bottom wall of the receiving groove 242 is spaced apart from the lower end of the atomizing channel 201. A fourth protrusion 243 is provided on the bottom wall of the receiving groove 242. The fourth protrusion 243 is hollow and through to form a part of the air inlet channel 241. The fourth protrusion 243 is offset from the lower end of the atomizing channel 201. The sealing member 12 is in contact with the bottom surface of base 24.

[0076] In this embodiment, it should be noted that, in specific implementation, the number of air intake channels 241 can be one or more, and the number of fourth protrusions 243 is the same as the number of air intake channels 241. The specific number of air intake channels 241 can be determined according to actual usage needs, and this embodiment does not impose specific restrictions on this.

[0077] In this embodiment, based on the above structural design, the operating principle of the electronic atomizing device provided in this embodiment is as follows:

[0078] The atomizing core 22 draws atomizing liquid from the liquid storage chamber 202, heats and atomizes it to produce vapor that the user can inhale. When the user bites the mouthpiece 25 and inhales, a suction airflow is formed along the path that connects the air inlet 112, air inlet channel 1110, vent 1210, groove 120, air intake channel 241, atomization channel 201, and mouthpiece 25. As the suction airflow passes through the atomizing core 22, it carries away the vapor produced by the atomizing core 22 and finally discharges it to the mouthpiece 25 for the user to inhale. During the inhalation process using the electronic atomizing device, some vapor condenses and forms condensate on the inner wall of the mouthpiece 25 and the inner wall of the atomization channel 201. Under the influence of gravity, the condensate flows along the inner wall of the mouthpiece 25 and the inner wall of the atomization channel 201. The condensate flows downwards and eventually drips at the lower port of the atomizing channel 201. Because the upper port of the fourth protrusion 243 is offset from the lower port of the atomizing channel 201, and the bottom wall of the receiving groove 242 is spaced apart from the lower port of the atomizing channel 201, the condensate dripping from the lower port of the atomizing channel 201 will not drip directly into the air inlet channel 241 and into the groove 120 of the seal 12. Instead, it will drip onto the bottom wall of the receiving groove 242 and accumulate. Only when the condensate accumulated on the bottom wall of the receiving groove 242 overflows the fourth protrusion 243 will it be able to fall into the groove 120 of the seal 12 for secondary accumulation. This further reduces the risk of damage to the control circuit board 14, battery 15, and microphone sensor 16 due to contact with the condensate. In a specific implementation, the protrusion height of the fourth protrusion 243 along the height direction of the base 24 can be set to 1–5 mm.

[0079] Further, please continue to refer to Figure 10-12 In some optional embodiments of this application, the atomizer 2 further includes an air duct 26 having at least a partial atomization channel 201. One end of the air duct 26 is sealed and connected to the mouthpiece 25, and the other end is sealed and engaged with the base 24. The housing 21, the base 24, and the air duct 26 together define a liquid storage chamber 202. At least one liquid outlet 260 communicating with the liquid storage chamber 202 is provided on the side wall of the air duct 26. A liquid storage cotton 27 is sandwiched between the outer wall of the atomizing core 22 and the inner wall of the air duct 26. The outer wall of the liquid storage cotton 27 is arranged to block each liquid outlet 260. The atomized liquid in the liquid storage chamber 202 can be conducted to the atomizing core 22 through the liquid outlet 260 and the liquid storage cotton 27 in sequence. That is, the atomizing core 22 and the liquid storage chamber 202 are connected through the liquid storage cotton 27 and the liquid outlet 260. With this configuration, the liquid storage cotton 27 can buffer the atomizing liquid, preventing the atomizing liquid flowing out of the liquid outlet 260 from being guided too quickly to the atomizing core 22, which would cause the atomizing core 22 to leak liquid. This reduces the risk of the atomizing liquid leaking from the air inlet 2410 into the power supply assembly 1.

[0080] It should be noted that other contents of the power supply component 1 and electronic atomizing device disclosed in this application can be found in the prior art, and will not be repeated here.

[0081] 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.
