Description

Technical Field

[0001] The present application belongs to the field of atomization technology, and more specifically, relates to a nozzle assembly, an atomization device, and an electronic atomizer. Background Art

[0002] An electronic atomizer is a device that heats an atomizing liquid to atomize it into an aerosol. The aerosol formed by the atomization of the atomizing liquid can be used for inhalation by the user.

[0003] An electronic atomizer may generally include an atomizing device and a power supply device. The power supply device is used to supply power to the atomizing device, and the atomizing device is used to heat the atomizing liquid and atomize it to form an aerosol.

[0004] The power supply device may include a housing, a circuit board disposed in the housing, a battery disposed in the housing and electrically connected to the circuit board, and an air pressure sensing element disposed on the circuit board. The atomizing device is provided with a starting airway, which is connected to the air pressure sensing element. During use, the airway is activated by suction, and the air pressure around the air pressure sensing element will change. The air pressure sensing element can sense the air pressure change and feed back the air pressure change signal to the circuit board. Based on the air pressure change signal, the circuit board can control the battery to power the atomizing device, so that the atomizing device achieves a suction start effect, thereby performing an atomization operation and atomizing the atomized liquid to form an aerosol.

[0005] In some cases, the priming airway has an opening exposed to the outside environment so that the user can inhale through the opening. However, this makes condensation more likely to form at the opening of the priming airway. The condensed liquid formed by condensation can easily flow through the priming airway to the air pressure sensing element, thereby affecting the use of the air pressure sensing element and thus affecting the puff-priming effect of the atomizer device.

This arrangement can alleviate the problem of the air pressure sensing element being easily affected by condensed liquid, resulting in a loss of suction-priming effect.

[0054] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0055] Please also refer to Figures 1 to 3 , and combined with other drawings. Figure 1 This is a three-dimensional structural diagram of the atomization device 100 provided in some embodiments of the present application. Figure 2 for Figure 1 Section view along AA, Figure 3 for Figure 2Enlarged view of point B in the figure. The nozzle assembly 10 provided in the embodiment of the present application is provided with a mist outlet duct 102 and a starting air duct 101. One end of the mist outlet duct 102 is used to be arranged opposite to the atomizing core 20 along the first direction Y, and the end of the mist outlet duct 102 away from the atomizing core 20 is used to connect to the outside of the nozzle assembly 10. The air inlet end of the starting air duct 101 is used to connect to the outside of the nozzle assembly 10. The starting air duct 101 and the mist outlet duct 102 are spaced apart along the second direction X, and the starting air duct 101 and the mist outlet duct 102 are connected. The first direction Y and the second direction X intersect.

[0056] The mist outlet air channel 102 and the starting air channel 101 are both air channels and flow channels in the nozzle assembly 10.

[0057] The mist outlet duct 102 has an air inlet end and an air outlet end.

[0058] The air inlet end of the mist outlet duct 102 refers to the end of the mist outlet duct 102 for gas to flow into the mist outlet duct 102. It is the portion of the mist outlet duct 102 at this end, not the endpoint or end surface. One end of the mist outlet duct 102 is the air inlet end of the mist outlet duct 102, which is arranged opposite the atomizer core 20 along the first direction Y. Specifically, the air inlet end of the mist outlet duct 102 can be used to at least allow the aerosol formed by atomization at the atomizer core 20 to flow into the mist outlet duct 102.

[0059] The air outlet end of the mist outlet duct 102 refers to the end of the mist outlet duct 102 for supplying the gas in the mist outlet duct 102 to flow out of the suction nozzle assembly 10. It is a part of this end of the mist outlet duct 102, not an end point or end face. The end of the mist outlet duct 102 away from the atomizing core 20 is the air outlet end of the mist outlet duct 102, which is used to connect to the outside of the suction nozzle assembly 10. That is, the air outlet end of the mist outlet duct 102 is connected to the space outside the suction nozzle assembly 10. Specifically, the air outlet end of the mist outlet duct 102 can be used at least to supply the gas in the mist outlet duct 102 to flow outside the suction nozzle assembly 10. Among them, the space outside the suction nozzle assembly 10 connected to the air outlet end of the mist outlet duct 102 can be, but is not limited to, the external environment.

[0060] The starting air passage 101 has an air inlet end and an air outlet end.

[0061] The air inlet end of the starting air duct 101 refers to the end of the starting air duct 101 for supplying gas from outside the nozzle assembly 10 to enter the starting air duct 101. It is a part of this end of the starting air duct 101, not an end point or end face. The air inlet end of the starting air duct 101 is used to connect to the outside of the nozzle assembly 10, which means that the air inlet end of the starting air duct 101 can connect to the space outside the nozzle assembly 10. When the nozzle assembly 10 and the power supply device 200 of the electronic atomizer 1000 are assembled, the air inlet end of the starting air duct 101 can be connected to the through hole 2201 on the circuit board 220 in the power supply device 200, that is, the space outside the nozzle assembly 10 connected to the air inlet end of the starting air duct 101 can be, but is not limited to, the through hole 2201 on the circuit board 220. In this way, the gas at the through hole 2201 can flow into the starting air channel 101 through the air inlet end of the starting air channel 101 under the action of suction, thereby causing the air pressure around the air pressure sensing element 240 at the through hole 2201 of the circuit board 220 to change. The specific structures of the power supply device 200, circuit board 220, through hole 2201, and air pressure sensing element 240 will be explained in detail below and will not be repeated here.

[0062] The gas outlet end of the starting gas channel 101 refers to an end of the starting gas channel 101 for allowing the gas in the starting gas channel 101 to flow out, and is a part of the end of the starting gas channel 101, rather than an end point or end surface.

[0063] The startup air channel 101 and the mist outlet channel 102 are connected, which means that the air outlet end of the startup air channel 101 is connected to the air inlet end of the mist outlet channel 102. In this way, the gas in the startup air channel 101 can flow into the mist outlet channel 102 through the air outlet end of the startup air channel 101 and the air inlet end of the mist outlet channel 102. The mist outlet channel 102 may have one or more air inlet ends, and the air inlet end of the mist outlet channel 102 that is arranged opposite to the atomizing core 20 and the air inlet end of the mist outlet channel 102 that is connected to the startup air channel 101 may be the same air inlet end or different air inlet ends.

[0064] The first direction Y is the approximate distribution direction of the mist passage 102 and the atomizing core 20 , and the second direction X is the approximate distribution direction of the mist passage 102 and the starting air passage 101 .

[0065] The intersection of the first direction Y and the second direction X means that the first direction Y and the second direction X can form an angle greater than 0° and less than 180°, that is, the first direction Y and the second direction X are not parallel. The first direction Y and the second direction X can be perpendicular to each other, or they can be non-perpendicular. The first direction Y and the second direction X can be directions intersecting on the same plane, or they can be directions on planes that are opposite to each other, and the projection of the second direction X on the plane where the first direction Y is located can intersect with the first direction Y. As an example, the first direction Y and the second direction X are perpendicular. The first direction Y can be the height direction of the atomizing device 100, and the second direction X can be the width direction of the atomizing device 100.

[0066] The nozzle assembly 10 provided in the embodiment of the present application is configured to connect the air inlet end of the starting air channel 101 to the outside of the nozzle assembly 10, connect the starting air channel 101 to the mist outlet channel 102, and connect the end of the mist outlet channel 102 away from the atomizing core 20 to the outside of the nozzle assembly 10, so that the air outlet end of the starting air channel 101 does not need to be directly connected to the outside of the nozzle assembly 10, but is indirectly connected to the outside of the nozzle assembly 10 through the mist outlet channel 102, thereby improving the problem that the air outlet end of the starting air channel 101 is prone to condensation, causing the air pressure sensing element 240 to be damaged by moisture and affecting the suction start effect. In this way, the user can inhale the end of the mist outlet channel 102 away from the nozzle assembly 10, so that the gas around the air pressure sensing element 240 can enter the starting air channel 101 through the air inlet end of the starting air channel 101, and then flow to the mist outlet channel 102, and flow out from the end of the mist outlet channel 102 away from the atomizing core 20, thereby achieving the suction start effect. Based on this, the atomizer core 20 can heat the atomizing liquid to atomize it to form an aerosol, and the aerosol can flow into the mist outlet channel 102 and then flow out of the nozzle assembly 10.

[0067] By arranging one end of the mist outlet duct 102 and the atomizer core 20 relative to each other along a first direction Y, and by spacing the priming air duct 101 and the mist outlet duct 102 along a second direction X, with the first direction Y and the second direction X intersecting, the mist outlet duct 102 and the priming air duct 101 are offset from each other. Thus, when condensation occurs at the end of the mist outlet duct 102 away from the atomizer core 20, the resulting condensed liquid has difficulty flowing from the mist outlet duct 102 to the priming air duct 101, and thus has difficulty flowing through the priming air duct 101 to the air pressure sensing element 240. For example, if the first direction Y is substantially the direction of gravity, and the atomizer core 20 is substantially located below the mist outlet duct 102 along the direction of gravity, the priming air duct 101 and the mist outlet duct 102 are offset substantially horizontally. Thus, when condensation occurs at the end of the mist outlet duct 102 away from the atomizer core 20, the resulting condensed liquid will flow to the atomizer core 20 under the action of gravity, and will have difficulty flowing to the priming air duct 101.

[0068] This configuration can improve the problem that the air pressure sensing element 240 is easily affected by condensed liquid, which may cause the suction start effect to fail.

[0069] In some embodiments, please refer to Figures 1 to 3 The end of the mist outlet 102 away from the atomizer core 20 passes through one end of the nozzle assembly 10 along the first direction Y, so that the air inlet and outlet ends of the mist outlet 102 are opposite and connected along the first direction Y.

[0070] Such arrangement makes it easier for the user to perform the suction operation.

[0071] In some embodiments, please refer to Figures 1 to 3 The air inlet end of the starting air passage 101 passes through one end of the nozzle assembly 10 along the first direction Y.

[0072] With this arrangement, after the nozzle assembly 10 and the power supply device 200 are assembled, the through hole 2201 on the circuit board 220 in the power supply device 200 is connected to the starting air channel 101, and the gas flow is facilitated.

[0073] In some embodiments, please refer to Figure 2 and Figure 3 , and in conjunction with other figures. The starting air duct 101 is provided with a first air inlet 1011 and a first air outlet 1012 spaced apart from each other. The first air inlet 1011 is connected to the outside of the nozzle assembly 10. The atomizing air duct 102 is provided with a second air inlet 1021 and a second air outlet 1022 spaced apart from each other. The second air outlet 1022 is connected to the outside of the nozzle assembly 10. The second air inlet 1021 is connected to the first air outlet 1012. In the first direction Y, the second air inlet 1021 is located between the first air outlet 1012 and the atomizing core 20.

[0074] The first air inlet 1011 and the first air outlet 1012 are arranged at opposite ends of the starting air channel 101 . The first air inlet 1011 is arranged at the air inlet end of the starting air channel 101 , and the first air outlet 1012 is arranged at the air outlet end of the starting air channel 101 .

[0075] The second air inlet 1021 is an air inlet of the mist outlet channel 102 for communicating with the starting air channel 101 and is provided at the air inlet end of the mist outlet channel 102. The second air outlet 1022 is provided at the air outlet end of the mist outlet channel 102.

[0076] It can be understood that the gas at the through hole 2201 of the circuit board 220 of the power supply device 200 can flow into the starting air channel 101 through the first air inlet 1011 of the starting air channel 101, and then enter the mist outlet channel 102 through the first air outlet 1012 of the starting air channel 101 and the second air inlet 1021 of the mist outlet channel 102 in turn, and finally flow out of the nozzle assembly 10 from the second air outlet 1022 of the mist outlet channel 102.

[0077] By locating the second air inlet 1021 between the first air outlet 1012 and the atomizer core 20 in the first direction Y, the difficulty of the condensed liquid flowing from the mist outlet channel 102 to the starting air channel 101 is increased, thereby further improving the problem that the condensed liquid condensed at the mist outlet channel 102 easily flows to the air pressure sensing element 240, causing the air pressure sensing element 240 to be damaged by moisture, thereby further improving the suction start effect of the electronic atomizer 1000.

[0078] It should be noted that, when the first direction Y is roughly the direction of gravity, and the atomizer core 20 is roughly located below the mist outlet channel 102 along the direction of gravity, the atomizer core 20 is roughly located below the second air inlet 1021 of the mist outlet channel 102 along the direction of gravity, and the first air outlet 1012 of the priming air channel 101 is located above the second air inlet 1021 along the direction of gravity. In this way, when condensation occurs at the end of the mist outlet channel 102 away from the atomizer core 20, the generated condensed liquid will flow to the atomizer core 20 under the action of gravity, and will have difficulty flowing upward to flow through the first air outlet 1012 to the priming air channel 101.

[0079] In some embodiments, please refer to Figure 2 and Figure 3 The second air inlet 1021 is provided at one end of the mist outlet channel 102 along the first direction Y close to the atomizer core 20 , and is used to be disposed opposite to the atomizer core 20 along the first direction Y.

[0080] It is understandable that the second air inlet 1021 is provided at the air inlet end of the mist outlet channel 102 that is disposed opposite the atomizer core 20 along the first direction Y. That is, the air inlet end of the mist outlet channel 102 that is disposed opposite the atomizer core 20 and the air inlet end of the mist outlet channel 102 that is communicated with the starting air channel 101 can be the same air inlet end. Specifically, the mist outlet channel 102 is disposed opposite the atomizer core 20 along the first direction Y through the second air inlet 1021.

[0081] Such a configuration allows the second air inlet 1021 to not only allow the gas in the starting airway 101 to flow into the mist outlet airway 102 for inhalation start, but also allow the mist at the atomizer core 20 to flow into the mist outlet airway 102, so that the mist formed by heating and atomization at the atomizer core 20 can be discharged. In this way, in order to allow the mist at the atomizer core 20 to flow smoothly through the second air inlet 1021 to the mist outlet airway 102, and then to flow out through the second air outlet 1022 of the mist outlet airway 102, the second air inlet 1021 is generally larger. In this way, during the inhalation start process, it is also convenient for the gas in the starting airway 101 to flow into the mist outlet airway 102, so as to achieve the inhalation start effect.

[0082] In other embodiments, the mist outlet channel 102 may be provided with multiple air inlet ends, and the air inlet end of the mist outlet channel 102 for being arranged opposite to the atomizer core 20 and the air inlet end of the mist outlet channel 102 for communicating with the starting air channel 101 may be different air inlet ends. That is, the second air inlet 1021 is provided at one portion of the air inlet ends of the mist outlet channel 102, and the other portion of the air inlet ends of the mist outlet channel 102 are arranged opposite to the atomizer core 20 along the first direction Y.

[0083] In some embodiments, please refer to Figures 2 to 4 , and combined with other drawings. Among them, Figure 4 A three-dimensional structural diagram of the shell 11 of the nozzle assembly 10 provided for some embodiments of the present application. The starting air channel 101 includes a first air channel 1013. The nozzle assembly 10 includes a shell 11 and a nozzle 12. The shell 11 is provided with the above-mentioned first air channel 1013 and a through groove 103. The first air channel 1013 and the through groove 103 are spaced apart along the second direction X. The first air channel 1013 passes through the shell 11, and the through groove 103 passes through the shell 11 along the first direction Y. At least part of the nozzle 12 covers the air outlet end of the first air channel 1013, and is surrounded by the shell 11 to form a connecting air channel 104. The nozzle 12 is provided with the above-mentioned mist outlet channel 102, which is used to be arranged opposite to the atomizing core 20 through the through groove 103. The mist outlet channel 102 and the first air channel 1013 are connected through the connecting air channel 104.

[0084] The first air channel 1013 is at least a portion of the starting air channel 101 and has an air inlet end and an air outlet end.

[0085] The air inlet end of the first air channel 1013 is an end of the first air channel 1013 for allowing gas to flow into the first air channel 1013 , and is a portion of the end of the first air channel 1013 , rather than an end point or end surface.

[0086] The outlet end of the first air channel 1013 is the end of the first air channel 1013 for gas to flow out and into the mist outlet channel 102. It is the portion of the first air channel 1013 at this end, not the end point or end surface. The outlet end of the first air channel 1013 is provided with the first air outlet 1012, that is, the first air outlet 1012 is provided on the housing 11.

[0087] The first air channel 1013 extends through the housing 11, meaning that both the air inlet and outlet of the first air channel 1013 are disposed through the housing 11. The first air channel 1013 extends through the housing 11, allowing the air inlet of the first air channel 1013 to communicate with the exterior of the housing 11, thereby directly or indirectly communicating with the exterior of the nozzle assembly 10 and, in turn, with the through hole 2201 on the circuit board 220 of the power supply device 200.

[0088] The nozzle 12 is provided with a mist outlet duct 102, which means that the air inlet and air outlet of the nozzle 12 are provided through the nozzle 12. Among them, the second air inlet 1021 of the air inlet end of the mist outlet duct 102 and the second air outlet 1022 of the air outlet end of the mist outlet duct 102 are both provided on the nozzle 12.

[0089] The mist outlet channel 102 is used to be arranged relative to the atomizer core 20 through the through groove 103, which means that in the first direction Y, at least a portion of the through groove 103 is arranged between the air inlet end of the mist outlet channel 102 and the atomizer core 20, and is respectively arranged relative to the air inlet end of the mist outlet channel 102 and the atomizer core 20, so that the mist outlet channel 102 can be arranged relative to the atomizer core 20 through the through groove 103, so that the aerosol at the atomizer core 20 can flow to the mist outlet channel 102 through the through groove 103.

[0090] The connecting air channel 104 refers to the air channel formed by the nozzle 12 and the housing 11, and is used to achieve communication between the first air channel 1013 of the starting air channel 101 and the mist outlet air channel 102. The first air channel 1013 and the mist outlet air channel 102 are connected through the connecting air channel 104, which means that the air outlet end of the first air channel 1013 is connected to the connecting air channel 104, and the connecting air channel 104 is connected to the air inlet end of the mist outlet air channel 102, that is, the first air outlet 1012 is connected to the connecting air channel 104, and the connecting air channel 104 is connected to the second air inlet 1021.

[0091] The nozzle assembly 10 includes a housing 11 and a nozzle 12 , which facilitates the setting of the starting air channel 101 and the mist outlet channel 102 .

[0092] In some embodiments, please refer to Figures 2 to 4, and in combination with other drawings. The nozzle 12 includes a mouth portion 121 and a connecting portion 122. The mouth portion 121 is provided with the above-mentioned mist outlet channel 102. At least part of the mouth portion 121 is inserted into the through groove 103, and is separated from the inner side wall of the through groove 103 to form a first gap 1041. The connecting air channel 104 includes the above-mentioned first gap 1041, and the first gap 1041 is connected between one end of the mist outlet channel 102 close to the atomizing core 20 along the first direction Y and the first air channel 1013. The connecting portion 122 is connected to the mouth portion 121, and at least part of the connecting portion 122 covers the outlet end of the first air channel 1013.

[0093] The nozzle 121 is provided with a mist outlet duct 102 , which means that the air inlet end and the air outlet end of the mist outlet duct 102 are provided through the nozzle 121 .

[0094] At least a portion of the nozzle 121 is inserted into the through slot 103 along the first direction Y. A portion of the through slot 103 is located between the atomizer core 20 and the nozzle 121 , so that the air inlet end of the mist outlet channel 102 and the atomizer core 20 are disposed opposite each other through the through slot 103 .

[0095] The end of the mist outlet channel 102 close to the atomizer core 20 along the first direction Y is the end of the nozzle 121 close to the atomizer core 20 along the first direction Y, which is the air inlet end of the mist outlet channel 102. The second air inlet 1021 of the air inlet end of the mist outlet channel 102 and the second air outlet 1022 of the air outlet end of the mist outlet channel 102 are both provided on the nozzle 121.

[0096] By adopting the above technical solution, the second air inlet 1021 at the air inlet end of the mist outlet duct 102 can not only be used to allow the gas in the starting air duct 101 to flow into the mist outlet duct 102 for inhalation start, but can also be used to allow the aerosol at the atomizer core 20 to flow into the mist outlet duct 102, so that the aerosol formed by heating and atomization at the atomizer core 20 can be discharged. In this way, during the inhalation start process, it is also convenient for the gas in the starting air duct 101 to flow into the mist outlet duct 102 to achieve the inhalation start effect. Moreover, in the first direction Y, the second air inlet 1021 is located between the first air outlet 1012 and the atomizer core 20, which increases the difficulty of condensed liquid flowing from the mist outlet duct 102 to the starting air duct 101, thereby further improving the problem that the condensed liquid formed by condensation at the mist outlet duct 102 easily flows to the air pressure sensing element 240, causing the air pressure sensing element 240 to be damaged by moisture, thereby further improving the inhalation start effect of the electronic atomizer 1000.

[0097] In some embodiments, as Figures 2 to 4 The first air channel 1013 can be arranged to pass through the housing 11 along the first direction Y, so that the air inlet and the air outlet of the first air channel 1013 are respectively arranged at opposite ends of the first air channel 1013 along the first direction Y.

[0098] In some embodiments, as Figures 2 to 4 As shown in the figure, and in combination with other figures, the mist outlet channel 102 can be arranged to pass through the nozzle 12 along the first direction Y. Specifically, the mist outlet channel 102 passes through the nozzle 121 along the first direction Y, so that the air inlet end and the air outlet end of the mist outlet channel 102 are respectively arranged at opposite ends of the mist outlet channel 102 along the first direction Y.

[0099] In this arrangement, the shell 11 and the suction nozzle 12 are roughly arranged in a sleeve manner along the first direction Y, so that at least part of the shell 11 can cover the air outlet end of the first air channel 1013, specifically, the connecting portion 122 can at least cover the air outlet end of the first air channel 1013.

[0100] In some embodiments, please refer to Figures 2 to 4 At least a portion of the connecting portion 122 is disposed at one end of the housing 11 along the first direction Y. The nozzle assembly 10 further includes a base assembly 13. At least a portion of the base assembly 13 is connected to the other end of the housing 11 along the first direction Y.

The connecting post 131 is sealedly connected to the through-slot 103. The connecting post 131 and the mouthpiece 121 are spaced apart along the first direction Y to form a second gap 1042. The communicating airway 104 also includes the aforementioned second gap 1042, and the mist outlet passage 102 and the atomizing chamber 105 are connected via the second gap 1042.

[0103] It can be understood that the atomizing chamber 105 passes through the end of the connecting column 131 close to the mouth 121 along the first direction Y, so that the atomizing chamber 105 and the mist outlet channel 102 can be connected through the second gap 1042.

[0104] The connecting post 131 is sealedly connected to the through groove 103, so that the connection position between the connecting post 131 and the through groove 103 is sealed, thereby achieving mutual isolation between the liquid storage chamber 106 and the atomization chamber 105, and between the liquid storage chamber 106 and the mist outlet passage 102. It can be understood that the atomized liquid in the liquid storage chamber 106 can penetrate into the atomization chamber 105 through the specific position of the connecting post 131, so that this part of the atomized liquid can be atomized to form an aerosol under the heating and atomization action of the atomization core 20, and flow through the second gap 1042 to the mist outlet passage 102.

[0105] The base assembly 13 is provided with a second air passage 1014 therethrough, and the second air passage 1014 is spaced apart from the connecting column 131. The starting air passage 101 further includes the second air passage 1014, which is connected to the first air passage 1013.

[0115] Specifically, the seal 15 abuts between the housing 11 and the suction nozzle 12. More specifically, when the first air passage 1013 passes through the housing 11 along the first direction Y, the seal 15 abuts between the housing 11 and the suction nozzle 12 along the first direction Y.

[0116] By adopting the above technical solution, the sealing member 15 can seal the air outlet end of the first air channel 1013, so that the gas in the first air channel 1013 can flow directionally to the connecting air channel 104 through the above opening of the air outlet end, and then flow to the mist outlet channel 102, and will not leak through other positions of the air outlet end of the first air channel 1013 as much as possible, thereby improving the suction start effect.

[0117] In some embodiments, please refer to Figures 2 to 4 , and in conjunction with other figures. The nozzle 12 is provided with a sealing groove 107, which is arranged opposite to the air outlet end of the first air duct 1013.

[0118] It can be understood that the air outlet end of the first air channel 1013 is provided on the mounting portion 111 .

[0119] Through the plug-in fit of the mounting portion 111 and the sealing groove 107, the seal 15 is limited in the sealing groove 107, and along the plug-in direction of the mounting portion 111 and the sealing groove 107, the seal 15 is abutted between the mounting portion 111 and the shell 11, so that the seal 15 can stably achieve the sealing effect on the air inlet end of the first air duct 1013.

[0124] The atomizing device 100 provided in the embodiment of the present application can improve the problem that the air pressure sensing element 240 is easily affected by condensed liquid by adopting the suction nozzle assembly 10 involved in the above embodiments, thereby improving the problem of failure of the suction start effect.

[0125] Please also refer to Figures 5 to 7 , and combined with other drawings. Among them, Figure 5 This is a three-dimensional structural diagram of the electronic atomizer 1000 provided in some embodiments of the present application. Figure 6 for Figure 5 Cross-sectional view along CC, Figure 7 for Figure 5 An enlarged view of point D in the figure. The electronic atomizer 1000 provided in this embodiment includes an atomizing device 100 and a power supply device 200.
