Description

Technical Field

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

[0002] An electronic atomizing device is an electronic device that can vaporize stored e-liquid, medicinal liquid, or other atomizing liquid into vapor through electric heating. An electronic atomizing device typically includes an atomizer and a power supply component. The atomizer generally includes a reservoir for storing the atomizing liquid, an atomizing core for absorbing the atomizing liquid and vaporizing it into vapor, and an air passage for expelling the vapor produced by the atomizing core to the outside. The power supply component supplies power to the atomizing core, which then heats up and vaporizes the absorbed atomizing liquid into vapor that the user can inhale.

[0003] In related technologies, during the process of users using electronic atomizing devices for inhalation, some vapor will remain in the airway and condense to form condensate. Under the influence of its own gravity, this condensate can easily leak along the inner wall of the airway to the outside of the atomizer and flow into the inside of the power supply component. Once the condensate comes into contact with the electronic components in the power supply component (such as the control circuit board, battery, microphone sensor, etc.), it can easily cause damage to the electronic components in the power supply component.

[0021] Compared with the prior art, this application has at least the following beneficial effects:

[0022] In the technical solution of this application, the bottom of the first housing of the atomizer is provided with a base located below the liquid storage chamber. The base is provided with a first receiving groove and an air inlet channel connected to the first air passage. The first receiving groove is located below the first air passage of the atomizer. The bottom wall of the first receiving groove is provided with a hollow first protrusion. The air inlet port of the air inlet channel is located on the bottom end face of the base. The air outlet port of the air inlet channel is the upper port of the first protrusion. The upper end of the first protrusion is offset from the air inlet port of the first air passage, and the vertical height between the upper end face of the first protrusion and the bottom wall of the first receiving groove is 1mm to 5mm. With this design, when the vapor produced by the atomizer core condenses in the first air passage to form condensate, on the one hand, because the air outlet of the air intake channel is offset from the air intake port of the first air passage, and the bottom wall of the first receiving groove is spaced apart from the air intake port of the first air passage, the condensate in the first air passage will not drip directly into the air intake channel and leak, but will drip onto the bottom wall of the first receiving groove and accumulate. On the other hand, because there is a height difference of 1 to 5 mm between the upper surface of the first protrusion and the bottom wall of the first receiving groove, the condensate dripping onto the bottom wall of the first receiving groove will be blocked by the first protrusion and will not easily flow into the air intake channel and leak. In both aspects, the risk of condensate leakage from the atomizer can be effectively reduced, thereby reducing the risk of condensate leakage from the atomizer into the power supply assembly and damaging the electronic components in the power supply assembly.

[0046] Please refer to Figure 1-6 One embodiment of this application provides an atomizer 1, which is used in combination with a power supply component 2 to form a complete electronic atomization device (e.g., Figure 7-9 As shown), the atomizer 1 includes a first housing 11, an atomizing core 12, and a base 13 (the base 13 can be made of plastic), wherein:

[0047] The interior of the first housing 11 is provided with a first air passage 101 and a liquid storage chamber 102 for storing atomizing liquid. The top of the first housing 11 is provided with a suction nozzle 14 (the material of the suction nozzle 14 can be plastic). The suction nozzle 14 is connected to the air outlet port of the first air passage 101 (i.e. the upper port of the first air passage 101).

[0048] The atomizing core 12 is installed inside the first housing 11 and communicates with the liquid storage chamber 102, so that the atomizing core 12 can draw atomizing liquid from the liquid storage chamber 102, heat and atomize it to produce a vapor that can be inhaled by the user; moreover, the atomizing core 12 is located in the first air passage 101 so that the vapor produced by the atomizing core 12 can be carried away by the suction airflow formed in the first air passage 101 and discharged to the mouthpiece 14 for the user to inhale;

[0049] The base 13 is installed at the bottom of the first housing 11. The base 13 has a first receiving groove 131 and an air intake channel 132 extending along the height direction of the base 13. The air intake port (i.e., the lower port of the air intake channel 132) is located on the bottom surface of the base 13. The air outlet port of the air intake channel 132 is connected to the air intake port (i.e., the lower port of the first air passage 101). The first receiving groove 131 is located below the liquid storage chamber 102. The bottom wall of the first receiving groove 131 is opposite to and spaced apart from the air intake port of the first air passage 101. A first protrusion 1311 protrudes from the bottom wall of the first receiving groove 131. The upper end of the first protrusion 1311 is offset from the air inlet port of the first air passage 101 (this can be understood as follows: assuming the vertical projection of the upper end of the first protrusion 1311 onto the bottom wall of the first receiving groove 131 is a first circle, and the vertical projection of the air inlet port of the first air passage 101 onto the bottom wall of the first receiving groove 131 is a second circle, then the first circle and the second circle do not overlap). The first protrusion 1311 is hollow to form a portion of the air inlet channel 132, and the upper port of the first protrusion 1311 is the air outlet port of the air inlet channel 132. The vertical height between the upper end face of the first protrusion 1311 and the bottom wall of the first receiving groove 131 is 1mm to 5mm. Figure 4 As shown, assuming the vertical height between the upper end face of the first protrusion 1311 and the bottom wall of the first receiving groove 131 is H1, then 1mm≤H1≤5mm.

[0050] In this embodiment, it should be noted that, in specific implementation, the number of intake channels 132 can be one or more, and the number of first protrusions 1311 is the same as the number of intake channels 132. The specific number of intake channels 132 can be determined according to actual usage needs, and this embodiment does not impose specific restrictions on this.

[0051] In this embodiment, based on the above structural design, the operating principle of the atomizer 1 provided in this embodiment is as follows:

[0052] The atomizing core 12 draws atomizing liquid from the liquid storage chamber 102, heats and atomizes it to produce vapor that the user can inhale. When the user bites the mouthpiece 14 and inhales, a suction airflow is formed along the path that connects the air intake channel 132, the first air passage 101, and the mouthpiece 14. As the suction airflow passes through the atomizing core 12, it carries away the vapor produced by the atomizing core 12 and finally discharges it to the mouthpiece 14 for the user to inhale. During the user's inhalation using the atomizer 1, some vapor condenses and forms condensate on the inner wall of the mouthpiece 14 and the inner wall of the first air passage 101. Under its own gravity, the condensate flows downward along the inner wall of the mouthpiece 14 and the inner wall of the first air passage 101 and finally drips at the lower end of the first air passage 101. Because the outlet of the air intake channel 132 and the inlet of the first air passage 101 are connected... The air ports are staggered, and the bottom wall of the first receiving groove 131 is spaced apart from the air inlet port of the first air channel 101. Therefore, the condensate dripping from the lower port of the first air channel 101 will not drip directly into the air inlet channel 132 and leak to the outside of the atomizer 1. Instead, it will drip onto the bottom wall of the first receiving groove 131 and accumulate. At the same time, since there is a height difference of 1 to 5 mm between the upper end face of the first protrusion 1311 and the bottom wall of the first receiving groove 131, the condensate dripping onto the bottom wall of the first receiving groove 131 will be blocked by the first protrusion 1311 and will not easily flow into the air inlet channel 132 and leak to the outside of the atomizer 1. This can effectively reduce the risk of condensate leakage from the atomizer 1, and further reduce the risk of condensate leakage from the atomizer 1 into the power supply assembly 2 and damaging the electronic components in the power supply assembly 2.

[0053] In this embodiment, it should be further noted that by setting the protrusion height of the first protrusion 1311 (i.e., the vertical height between the upper end face of the first protrusion 1311 and the bottom wall of the first receiving groove 131) to 1-5mm, it can be avoided that the protrusion height of the first protrusion 1311 is set too small (less than 1mm), which would prevent it from effectively blocking the condensate accumulated on the bottom wall of the first receiving groove 131 in a short time. That is, by setting the protrusion height of the first protrusion 1311 to not less than 1mm, the accumulation of condensate on the bottom wall of the first receiving groove 131 can be effectively delayed. The time it takes for the condensate on the bottom wall of the tank 131 to flow into the air intake channel 132 from the upper port of the first protrusion 1311 (i.e., the condensate on the bottom wall of the first receiving tank 131 needs to accumulate to a liquid level of at least 1 mm before it can flow into the air intake channel 132); on the other hand, it can avoid the first protrusion 1311 being set too high (greater than 5 mm), which would cause a large airflow noise at the upper port of the first protrusion 1311 when the user bites the suction nozzle 14 to suck, due to the excessive vertical height of the air intake channel 132.

[0054] Further, please refer to Figure 3-6 In some optional embodiments of this application, the atomizer 1 further includes a liquid absorber 15 made of a porous material (which may be fiber cotton, sponge, porous ceramic, etc.). The liquid absorber 15 is disposed in the first receiving groove 131, and at least part of the liquid absorber 15 is positioned directly opposite the air inlet port of the first air passage 101 (that is, at least part of the liquid absorber 15 is positioned directly below the air inlet port of the first air passage 101). With this configuration, the liquid absorber 15 can absorb the condensate dripping from the air inlet port of the first air passage 101, thereby making it difficult for the condensate to accumulate on the bottom wall of the first receiving groove 131 and overflow the upper port of the first protrusion 1311 into the air inlet channel 132. In other words, it helps to further reduce the risk of condensate leakage from the atomizer 1.

[0055] Further, please refer to Figure 3-4 and Figure 6 In some optional embodiments of this application, the protrusion height of the first protrusion 1311 can be set to be greater than the thickness of the liquid absorbing 15. Specifically, the vertical height H2 between the upper end face of the liquid absorbing 15 and the bottom wall of the first receiving groove 131 is less than the vertical height H1 between the upper end face of the first protrusion 1311 and the bottom wall of the first receiving groove 131. With this setting, even if the liquid absorbing 15 reaches saturation due to continuous absorption of condensate, the condensate overflowing from the surface of the liquid absorbing 15 is less likely to overflow the upper port of the first protrusion 1311 and enter the air intake channel 132, thereby further reducing the risk of condensate leakage in the atomizer 1. In specific implementations, the height difference between the upper end face of the liquid absorbing 15 and the upper end face of the first protrusion 1311 can be set to 0.5 to 2 mm.

[0056] Further, please refer to Figure 5-6In some alternative embodiments of this application, the protrusion height of the first protrusion 1311 can be set to be less than the thickness of the liquid absorber 15. Specifically, the liquid absorber 15 is made of fiber cotton or sponge. The vertical height between the upper end face of the first protrusion 1311 and the bottom wall of the first receiving groove 131 is 2mm to 4mm. The liquid absorber 15 is provided with a through hole 151 extending along the height direction of the liquid absorber 15. The first protrusion 1311 is located in the through hole 151 (that is, the protrusion height of the first protrusion 1311 is not greater than the hole depth of the through hole 151). There is a height difference between the upper end face of the liquid absorber 15 and the upper end face of the first protrusion 1311, which is 1mm to 3mm. This design not only prevents condensate from accumulating on the bottom wall of the first receiving tank 131, but also allows the absorbent material 15, made of fiber cotton or sponge, to absorb airflow noise at the upper end of the first protrusion 1311 to a certain extent, thus achieving a certain noise reduction effect (the absorbent material 15 can act as "noise-absorbing cotton" at this time). This further reduces the risk of the atomizer 1 generating significant airflow noise during the user's inhalation process by biting the mouthpiece 14.

[0057] Furthermore, in some optional embodiments of this application, the specific structural composition of the atomizer 1 can be as follows:

[0058] Please refer to Figure 1 and Figure 3-6 The first housing 11 includes an outer shell 111 (the material of the outer shell 111 can be plastic), a sealing seat 112 (the material of the sealing seat 112 can be silicone, rubber, or silicone rubber), and an airway tube 113 with an atomization channel 1131 (the material of the airway tube 113 can be stainless steel or hard plastic). A nozzle 14 is connected to the top of the outer shell 111, and the sealing seat 112 is sealed within the bottom of the outer shell 111. A first mounting through hole 1111 is provided in the top of the outer shell 111, and the sealing seat 112 is provided with a connection to the first mounting through hole 1111. The second mounting through holes 1122 are arranged at intervals relative to the mounting through holes 1111. The upper end of the airway tube 113 is sealed and fitted into the first mounting through hole 1111 by means of a sealing ring or the like. The other end of the airway tube 113 is sealed and fitted into the second mounting through hole 1122. The outer shell 111, the sealing seat 112, and the airway tube 113 together define the liquid storage chamber 102. The second mounting through hole 1122, the atomizing channel 1131, and the first mounting through hole 1111 are sequentially connected to form at least a portion of the first airway 101 (illustratively, as shown in the figure). Figure 3As shown, the lower port of the second mounting through hole 1122 can be regarded as the air inlet port of the first air passage 101, and the upper port of the first mounting through hole 1111 can be regarded as the air outlet port of the first air passage 101. The side wall of the air passage tube 113 is provided with a liquid outlet hole 1130 that communicates with the liquid storage chamber 102. The atomizing core 12 is installed in the air passage tube 113 and covers the liquid outlet hole 1130 (that is, the atomizing core 12 is connected to the liquid storage chamber 102 through the liquid outlet hole 1130). The base 1 3. The base 13 is fixedly fitted to the bottom end of the outer casing 111 (specifically, the fit between the base 13 and the bottom end of the outer casing 111 can be an interference fit or a transition fit), and the first receiving groove 131 of the base 13 is located below the sealing seat 112. A ventilation space 130 is formed between the bottom wall of the first receiving groove 131 and the sealing seat 112. The air outlet of the air inlet channel 132 is connected to the air inlet port of the first air passage 101 through the ventilation space 130 (exemplary, such as...). Figure 3 As shown, the lower side of the sealing seat 112 is recessed with an air passage 1121 that is correspondingly connected to the lower port of the second mounting through hole 1122. The diameter of the air passage 1121 is larger than the diameter of the lower port of the second mounting through hole 1122. There is a gap 1301 between the lower surface of the sealing seat 112 and the upper surface of the liquid absorbing 15. The gap 1301 is connected to the air passage 1121 to form a ventilation space 130. A portion of the upper end face of the first protrusion 1311 abuts against the lower surface of the sealing seat 112, and the upper port of the first protrusion 1311 is correspondingly connected to the air passage 1121. That is, the upper port of the first protrusion 1311 is not covered by the lower surface of the sealing seat 112. The atomizer 1 also includes a first electrode assembly 16 that is electrically connected to the atomizing core 12. The first electrode assembly 16 is fixed in the base 13 and the lower end face of the first electrode assembly 16 is exposed on the bottom end face of the base 13.

[0059] In this embodiment, the above structural design helps to improve the ease of assembly of the atomizer 1. Specifically, when manufacturing the atomizer 1 of this embodiment, the atomizing core 12 is first installed into the airway tube 113, and the outer wall of the atomizing core 12 covers the liquid outlet 1130 of the airway tube 113. Then, the lower end of the airway tube 113 containing the atomizing core 12 is inserted into the second mounting through hole 1122 of the sealing seat 112. Next, the liquid 15 and the first electrode assembly 16 are respectively installed in the base 13, and the electrode pins of the atomizing core 12 are electrically connected to the first electrode assembly 16 by means of crimping or the like. Then, the base 13 is installed on the lower side of the sealing seat 112 by means of insertion or the like. Then, the sealing seat 112 containing the airway tube 113 and the base 13 is installed into the bottom of the outer shell 111, and the upper end of the airway tube 113 is inserted into the first mounting through hole 1111 of the outer shell 111, and the base 13 is engaged with the bottom end of the outer shell 111. Finally, the mouthpiece 14 is installed on the top of the outer shell 111. This completes the assembly process of the atomizer 1, which is relatively convenient. The first electrode assembly 16 is designed to facilitate the electrical connection of the atomizer core 12 to the control circuit board 23 of the power supply assembly 2 when the atomizer 1 and the power supply assembly 2 are combined into a complete electronic atomization device.

[0060] Correspondingly, please refer to Figure 7-9 This application also provides an electronic atomizing device, which includes a power supply component 2 (such as...). Figure 11-12 (as shown) and the atomizer 1 in any of the above embodiments (such as Figure 1-6 As shown, the power assembly 2 includes a second housing 21, a battery 22, and a control circuit board 23. The second housing 21 has a receiving groove 210 for receiving the bottom end of the first housing 11. The bottom end of the first housing 11 is inserted into the receiving groove 210, and the top of the first housing 11 is detachably connected to the top of the second housing 21. The battery 22 and the control circuit board 23 are both installed inside the second housing 21. The control circuit board 23 is electrically connected to the battery 22 and the atomizing core 12, respectively. The control circuit board 23 can control the battery 22 to supply power to the atomizing core 12, so that... The atomizing core 12 can be powered to perform atomization; the second housing 21 is also provided with a second air passage 212. The air inlet of the second air passage 212 is connected to the outside, and the air outlet of the second air passage 212 is connected to the air inlet of the first air passage 101. When the user bites the mouthpiece 14 to inhale, outside air can flow into the second air passage 212 through the air inlet of the second air passage 212, and form a suction airflow in the airflow path that connects the second air passage 212, the air inlet passage 132, the first air passage 101, and the mouthpiece 14 in sequence.

[0061] In this embodiment, it should be noted that the second shell 21 can be an integral structure or a split structure assembled from different shell structures. Its specific structural form can be determined according to actual use needs, and this embodiment does not impose specific restrictions on it.

[0062] In this embodiment, it should also be noted that, in specific implementation, the detachable connection between the first housing 11 and the second housing 21 can be a magnetic connection (in which case the bottom wall of the receiving groove 210 and the bottom end face of the base 13 are respectively provided with magnets that can attract each other), a snap-fit ​​connection, etc., and this embodiment does not impose specific limitations on this. Exemplarily, in some optional embodiments, the detachable connection between the first housing 11 and the second housing 21 can be a snap-fit ​​connection, specifically, such as... Figure 1 , Figure 3 , Figure 8-9 and Figure 11 As shown, the top sidewall of the second housing 21 is provided with a locking hole 218, and the sidewall of the first housing 11 along its circumference is provided with a buckle 1112 that matches the locking hole 218. The bottom of the first housing 11 is inserted into the receiving groove 210, and the buckle 1112 is engaged with the locking hole 218, so that the first housing 11 and the second housing 21 can be stably connected together. When the atomizer 1 needs to be replaced because the atomizing liquid in the liquid storage chamber 102 is consumed by the atomizing coil 12, simply pull the atomizer 1 upward to disengage the buckle 1112 from the locking hole 218, thus removing the atomizer 1 from the second housing 21 of the power assembly 2. When a new atomizer 1 needs to be assembled onto the power assembly 2, simply insert the bottom of the atomizer 1 into the receiving groove 210 of the second housing 21, and let the buckle 1112 engage with the locking hole 218, thus completing the installation process of the atomizer 1. In other words, the installation and removal of atomizer 1 can be completed simply by plugging and unplugging it, which is quite convenient.

[0063] In this embodiment, thanks to the improvement of the atomizer 1, the electronic atomizing device provided in this embodiment has the same technical effect as the atomizer 1, which will not be described again here.

[0064] Furthermore, to facilitate the electrical connection between the atomizer coil 12 and the control circuit board 23 after inserting the bottom of the atomizer 1 into the receiving slot 210 of the second housing 21, please refer to the following... Figure 1 and Figure 9-10In some optional embodiments of this application, the power supply assembly 2 further includes a second electrode assembly 26. The second electrode assembly 26 is electrically connected to the control circuit board 23 via wires or the like. The upper end of the second electrode assembly 26 is exposed within the receiving groove 210, and the upper end of the second electrode assembly 26 is in electrical contact with the lower end of the first electrode assembly 16 of the atomizer 1. In specific implementations, the first electrode assembly 16 can be in the form of a conductive pin, and the second electrode assembly 26 can be in the form of a conductive spring pin.

[0065] Further, please refer to Figure 8 and Figure 11 In some optional embodiments of this application, the interior of the second housing 21 is further provided with an installation space 219 that is offset from the receiving groove 210 (exemplarily, such as...). Figure 11 As shown, the mounting space 219 is separated from the receiving slot 210 along the left-right direction of the electronic atomizing device. The battery 22 and the control circuit board 23 are both installed in the mounting space 219. With this arrangement, since the battery 22 and the control circuit board 23 are not located below the atomizer 1, even if the atomizer 1 experiences leakage of atomizing liquid or condensate, the atomizing liquid or condensate is unlikely to penetrate into the battery 22 and the control circuit board 23. This further reduces the risk of condensate or atomizing liquid leaking from the atomizer 1 into the power assembly 2 and damaging the battery 22 and the control circuit board 23 in the power assembly 2.

[0066] Furthermore, please refer to the following: Figure 1 , Figure 3-4 as well as Figure 8-12In some optional embodiments of this application, the bottom wall of the receiving groove 210 is recessed with a second receiving groove 2101. The bottom wall of the second receiving groove 2101 is spaced apart from the air inlet port of the air inlet channel 132. The bottom wall of the second receiving groove 2101 is protruded with a second protrusion 2102 located within the second receiving groove 2101. The upper end of the second protrusion 2102 is offset from the air inlet port of the air inlet channel 132. (It can be understood here that the upper end of the second protrusion 2102 is located within the second receiving groove 2101.) The vertical projection on the bottom wall of 01 is a third circle, and the vertical projection of the air intake port of the air intake channel 132 on the bottom wall of the second receiving groove 2101 is a fourth circle (the third circle and the fourth circle do not overlap). The second protrusion 2102 is hollow to form a part of the second air passage 212. The upper port of the second protrusion 2102 is the air outlet port of the second air passage 212, and the vertical height H3 between the upper end face of the second protrusion 2102 and the bottom wall of the second receiving groove 2101 is 0.3mm to 2mm. With this design, on the one hand, even if the atomizer 1 experiences leakage of atomizing liquid or condensate, the atomizing liquid or condensate flowing out of the air intake channel 132 of the atomizer 1 is unlikely to flow directly into the interior of the second housing 21 through the upper port of the second protrusion 2102. Instead, it will drip onto the bottom wall of the second receiving groove 2101 and accumulate. On the other hand, since the atomizer 1 can be disassembled relative to the power assembly 2, when condensate or atomizing liquid accumulates in the second receiving groove 2101, the user can remove the atomizer 1 from the receiving groove 210 of the power assembly 2 and then clean the condensate or atomizing liquid in the second receiving groove 2101. Both of these aspects help to further reduce the risk of condensate or atomizing liquid in the atomizer 1 leaking into the interior of the power assembly 2 and damaging the electronic components in the power assembly 2.

[0067] Further, please refer to Figure 7-12In some optional embodiments of this application, the power supply assembly 2 further includes an air regulating assembly 24. The air regulating assembly 24 includes a pusher 241, a slider 242 slidably mounted within the second housing 21 along its height direction, and a fixing member 243 fixed within the second housing 21. An air inlet 213 is provided on the outer wall of the second housing 21 along its circumference. This air inlet 213 can be considered as the air inlet port of the second air passage 212. The air inlet 213 extends along the height direction of the second housing 21. One end of the pusher 241 is fixedly connected to the slider 242, and the other end passes through the air inlet 213 and protrudes from the second housing 21. The slider 242 is located between the air inlet 213 and the fixing member 243. The slider 242 is made of a rigid material (such as rigid plastic or metal). The second housing 21 is made of a flexible material (such as silicone, rubber or silicone rubber) and the sliding member 242 is provided with a first vent 2420 corresponding to the air inlet 213. The fixing member 243 is provided with a second vent 2430 corresponding to the first vent 2420. The second housing 21 is also provided with a first chamber 214 located below the second protrusion 2102. Along the height direction of the second housing 21, the bottom wall of the first chamber 214 is lower than the hole wall of the second vent 2430 and the minimum vertical height between the bottom wall of the first chamber 214 and the hole wall of the second vent 2430 is 2mm to 8mm. The second vent 2430, the first chamber 214 and the inner cavity of the second protrusion 2102 are connected in sequence to form a part of the second air passage 212.

[0068] In this embodiment, based on the above structural design, on the one hand, by setting the air regulating component 24 corresponding to the air inlet 213, the electronic atomizing device can have the function of adjusting the suction airflow, thereby improving the user experience. For example, as shown in the example... Figure 8 and Figure 11As shown, when the sliding member 242 is pushed upward by the pusher 241, part of the air inlet of the first vent 2420 is blocked by the inner wall of the second housing 21, and part of the air outlet of the first vent 2420 is blocked by one side surface of the fixing member 243. This reduces the cross-sectional area of ​​the airflow through the first vent 2420 (i.e., the airflow through the first vent 2420 is reduced). Consequently, when the user bites the mouthpiece 14 to inhale, the suction airflow formed along the path connecting the second airway 212, the air inlet channel 132, the first airway 101, and the mouthpiece 14 in sequence will decrease, thus increasing the concentration of aerosol that the user can inhale. When the user wants to inhale a lower concentration of aerosol, the pusher 241 pushes the sliding member 242 downward, increasing the cross-sectional area of ​​the airflow through the first vent 2420. The sliding member 242 is made of a rigid material, and the fixing member 243... Made of flexible material, this design improves the airtightness between the sliding member 242 and the fixing member 243. On the other hand, since the second housing 21 also has a first chamber 214 located below the second protrusion 2102, the bottom wall of the first chamber 214 is lower than the wall of the second vent 2430, and the minimum vertical height between the bottom wall of the first chamber 214 and the wall of the second vent 2430 is 2mm to 8mm, even if the condensate or atomized liquid in the second receiving tank 2101 overflows the upper port of the second protrusion 2102, the condensate or atomized liquid flowing in from the upper port of the second protrusion 2102 can drip into the first chamber 214 for temporary storage, and is unlikely to flow directly to the air inlet 213. This reduces the risk of the condensate or atomized liquid in the atomizer 1 leaking into the power supply assembly 2 and leaking from the air inlet 213, thus affecting the cleanliness and hygiene of the electronic atomizing device.

[0069] Furthermore, please refer to the following: Figure 1 , Figure 3-4 as well as Figure 8-12 In some optional embodiments of this application, the bottom wall of the second receiving groove 2101 is provided with a third protrusion 2103 located within the second receiving groove 2101. The upper end of the third protrusion 2103 is offset from the air inlet port of the air inlet channel 132 (it can be understood here that, assuming the vertical projection of the air inlet port of the air inlet channel 132 on the bottom wall of the second receiving groove 2101 is a fourth circle, and the vertical projection of the upper end of the third protrusion 2103 on the bottom wall of the second receiving groove 2101 is a fifth circle, then the fourth circle and the fifth circle do not overlap). The third protrusion 2103 is hollow and forms a sensing channel 21030 extending along the height direction of the third protrusion 2103. The vertical height between the upper end surface of the third protrusion 2103 and the bottom wall of the second receiving groove 2101 is 0.5mm to 3mm. The second housing 21 is also provided with a microphone mounting position 217 and a bent connecting channel 216 (exemplarily, such as...). Figure 11 As shown, a portion of the connecting channel 216 is arranged horizontally, and a portion of the connecting channel 216 is arranged vertically. A second chamber 215 is separated from the second air passage 212. The second chamber 215 is located below the third protrusion 2103 and is connected to the sensing channel 21030. The microphone mounting position 217 is connected to the second chamber 215 through the connecting channel 216. The microphone mounting position 217 is offset from the liquid storage chamber 102, and along the height direction of the second housing 21, the bottom wall of the microphone mounting position 217 is higher than the top wall of the second chamber 215. The power supply assembly 2 also includes a microphone sensor 25 sealed and installed in the microphone mounting position 217. The microphone sensor 25 is electrically connected to the control circuit board 23.

[0070] In this embodiment, based on the above structural design, when the user bites the mouthpiece 14 to inhale, the suction airflow formed along the path connecting the second airway 212, the air inlet channel 132, the first airway 101, and the mouthpiece 14 will create a negative pressure at the upper port of the third protrusion 2103 when the suction airflow flows through the second receiving groove 2101. This negative pressure will trigger the microphone sensor 25 to send a suction signal to the control circuit board 23 to indicate that the user is inhaling. When the control circuit board 23 receives the suction signal, it controls the battery 22 to supply mist. The atomizing core 12 is powered by electricity, enabling it to atomize. When the user stops inhaling, the airflow disappears, causing the negative pressure at the upper port of the third protrusion 2103 to disappear. This triggers the microphone sensor 25 to send a stop signal to the control circuit board 23, indicating that the user has stopped inhaling. When the control circuit board 23 receives this stop signal, it controls the battery 22 to stop supplying power to the atomizing core 12, thus de-energizing and stopping the atomizing core 12. This improves the intelligence of the electronic atomizing device.

[0071] In this embodiment, it should be noted that, firstly, since the microphone mounting position 217 is offset from the liquid storage chamber 102, that is, the microphone sensor 25 is not located directly below the liquid storage chamber 102, even if the atomizing liquid in the liquid storage chamber 102 leaks and flows downward, it is difficult to contact the microphone sensor 25; secondly, since the upper end of the third protrusion 2103 is offset from the air inlet port of the air inlet channel 132 and the vertical height between the upper end surface of the third protrusion 2103 and the bottom wall of the second receiving groove 2101 is 0.5mm to 3mm, even if the atomizer 1 experiences atomizing liquid leakage or condensate leakage, the atomizing liquid or condensate flowing out of the air inlet channel 132 of the atomizer 1 is difficult to flow directly to the microphone sensor 25 through the upper port of the third protrusion 2103, but will drip onto the bottom wall of the second receiving groove 2101 and accumulate. Thirdly, since a second chamber 215 is provided below the third protrusion 2103, and the bottom wall of the microphone mounting position 217 is higher than the top wall of the second chamber 215, even if the condensate or atomizing liquid in the second receiving tank 2101 overflows the upper port of the third protrusion 2103 due to excessive accumulation, the condensate or atomizing liquid flowing in from the upper port of the third protrusion 2103 can drip into the second chamber 215 for temporary storage, and is unlikely to flow directly to the microphone sensor 25; fourthly, since the connecting channel 216 is bent, even if there is condensate or atomizing liquid in the second chamber 215, the condensate or atomizing liquid in the second chamber 215 is unlikely to flow quickly along the connecting channel 216 to the microphone sensor 25; thus, these four aspects greatly reduce the risk of condensate or atomizing liquid in the atomizer 1 leaking into the power supply assembly 2 and damaging the microphone sensor 25.

[0072] Furthermore, to ensure that the atomizer 1 can be reused without replacement after the atomizing coil 12 has consumed all the atomizing liquid in the reservoir 102 of the atomizer 1, thereby reducing the user's operating costs, please refer to... Figure 7-9 and Figure 11In some optional embodiments of this application, the electronic atomizing device further includes a liquid reservoir 3, which includes a third housing 31, a liquid outlet pipe 32, and a pumping assembly 33 (the pumping assembly 33 can be a structure with liquid pumping function, such as an electric pump). The base 13 of the atomizer 1 also has a pipe portion 133 that penetrates the sealing seat 112 and extends into the liquid storage chamber 102. The second housing 21 also has a receiving cavity 211 for accommodating at least a portion of the third housing 31. The interior of the third housing 31 is provided with a storage cavity 30 for storing atomized liquid. At least a portion of the third housing 31 is detachably installed in the receiving cavity 211 of the second housing 21 by means of snap-fit ​​connection or magnetic connection. One end of the liquid outlet pipe 32 is connected to the top of the third housing 31, and the other end extends into the pipe portion 133 of the base 13. The pumping assembly 33 is at least partially disposed inside the third housing 31. With this configuration, when the atomizing liquid in the storage chamber 102 of the atomizer 1 is consumed by the atomizing core 12, the pump assembly 33 can be operated to pump the atomizing liquid in the storage chamber 30 through the outlet pipe 32 to the storage chamber 102 of the atomizer 1 for replenishment, thereby enabling the atomizer 1 to be reused.

[0073] Correspondingly, this application embodiment also provides a power supply device, which can be connected to the atomizer 1 mentioned in any of the above embodiments (such as...). Figure 1-9 (As shown) can be detachably combined and used, and the power supply device is the power supply component 2 in the electronic atomizing device of any of the above embodiments (such as... Figure 7-9 and Figure 11-12 (As shown).

[0074] In this embodiment, it should be noted that other contents of the power supply device provided in this embodiment can be referred to the description of the power supply component 2 in the above embodiment of the electronic atomization device, and will not be repeated here.

[0075] 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.
