Description

Technical Field

[0001] The present application relates to the field of electronic atomization technology, and in particular to an electronic atomization device. Background Art

[0002] An electronic atomization device is a device that can atomize an aerosol matrix into an aerosol for users to use. It has been widely used in the electronic cigarette, medical, beauty and other industries.

[0003] In the related art, the electronic atomization device takes in air through the air inlet, and atomizes the aerosol matrix into an aerosol through the atomization component, and then discharges the aerosol through the air outlet of the mouthpiece through the atomization channel inside the atomization component to the outside for the user to inhale. In this process, part of the airflow entering the air inlet channel from the air inlet will enter the atomization channel to participate in the aerosol generation process, and the other part will pass through the air flow sensor located at the air inlet channel for detection. Since a small part of the aerosol will be cooled and liquefied in the atomization channel to form condensate, the residual condensate will easily flow into the air inlet channel and affect the detection accuracy of the air flow sensor, so the air inlet channel and the atomization channel will be staggered.

[0004] However, although this staggered arrangement can improve the impact of condensate on the airflow sensor, it will cause the flow path of the airflow entering the atomization channel to be longer, making the process of users inhaling aerosol more laborious and affecting the user experience.

DETAILED DESCRIPTION

[0037] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0038] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0040] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

[0041] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0042] In the related art, the electronic atomization device takes in air through the air inlet, and atomizes the aerosol matrix into an aerosol through the atomization component, and then discharges the aerosol through the air outlet of the nozzle through the atomization channel in the atomization component to the outside for the user to inhale.

[0043] During this process, part of the airflow entering the intake channel from the air inlet enters the atomization channel to participate in the aerosol generation process, while the remaining part is detected by the airflow sensor located in the intake channel. Because a small amount of aerosol cools and liquefies in the atomization channel to form condensate, the residual condensate can easily flow into the intake channel and affect the detection accuracy of the airflow sensor. Therefore, the intake channel and atomization channel are staggered.

[0044] However, although this staggered arrangement can improve the impact of condensate on the airflow sensor, it will cause the flow path of the airflow entering the atomization channel to be longer, making the process of users inhaling aerosol more laborious, affecting the user experience. In addition, the electronic atomization device in the related art also has the problem that the air intake at the air inlet is constant and cannot be adjusted, resulting in the inability to adjust the taste of the aerosol. There is also a problem that the sealing effect between the nozzle and the inner shell of the atomization assembly is poor, resulting in the aerosol matrix easily leaking from the assembly gap between the nozzle and the inner shell.

[0045] like Figures 1 to 3 As shown, in order to solve the above technical problems, an embodiment of the present application provides an electronic atomization device 100, which relates to the field of electronic atomization technology and is mainly used to atomize an aerosol matrix to form an aerosol for use by users.

[0046] Combine Figures 4 to 6 As shown, the electronic atomization device 100 provided in this embodiment includes: an outer shell 110 , a nozzle 120 , an airflow sensor 140 , an atomization assembly 150 and an air inlet 160 .

[0047] Among them, the outer shell 110 is provided with a accommodating cavity 113. The outer shell 110 is provided with a first air inlet 111 and a second air inlet 112 that are not connected to each other. The suction nozzle 120 is provided through the outer shell 110, and the suction nozzle 120 is provided with a first air outlet 1211 and a second air outlet 1212 that are not connected to each other, that is, the first air outlet 1211 and the second air outlet 1212 are located at different positions of the suction nozzle 120 to achieve mutual non-communication. The suction nozzle 120 and the accommodating cavity 113 define a detection channel 193 connected to the outside, that is, a detection channel 193 is formed between the second air inlet 112 and the second air outlet 1212, that is, the detection channel 193 is connected between the second air inlet 112 and the second air outlet 1212. The inner shell 151 is accommodated in the outer shell 110, one end of the inner shell 151 is connected to the suction nozzle 120, and the other end of the inner shell 151 has an opening 1512. The airflow sensor 140 is disposed within the outer housing 110 and is located within the detection channel 193 and near the nozzle 120. The atomizer assembly 150 is disposed within the outer housing 110, specifically within the inner housing 151, and has an atomizer channel 1541 that communicates with the first air outlet 1211 and the opening 1512. The air inlet member 160 is disposed between the outer housing 110 and the inner housing 151 and is located at the opening 1512, and is configured to communicate with the opening 1512 and the outside.

[0048] In some other embodiments, the first air inlet 111 and the second air inlet 112 may also share a common air inlet.

[0049] On this basis, the air inlet member 160 is arranged at the first air inlet port 111, and the air inlet member 160 is arranged at the end of the atomizer assembly 150 away from the suction nozzle 120. The air inlet member 160 and the inner wall of the outer shell 110 jointly define a first air inlet cavity 1611, and the first air inlet cavity 1611 is connected to the first air inlet port 111. The air inlet member 160 and the atomizer assembly 150 jointly define a second air inlet cavity 1621, and the second air inlet cavity 1621 is connected to the atomization channel 1541, and a through hole 1631 is opened on the air inlet member 160, and the through hole 1631 connects the first air inlet cavity 1611 and the second air inlet cavity 1621. The projections of the through hole 1631 and the atomization channel 1541 in the axial direction of the electronic atomizer device 100 at least partially do not overlap.

[0050] For example, the airflow sensor 140 may be a microphone, a pressure difference sensor, a flow sensor, or other element capable of detecting airflow parameters.

[0051] It is understood that when a user uses the electronic atomization device 100 and inhales the aerosol through the first air outlet 1211 of the mouthpiece 120, the airflow entering from the first air inlet 111 first enters the first air inlet cavity 1611 of the air inlet member 160 for a first buffering process, then passes through the through hole 1631 to enter the second air inlet cavity 1621 for a second buffering process, and finally enters the atomization channel 1541 of the atomization assembly 150 to participate in the aerosol generation process. In addition, the through hole 1631 can correct the direction of the airflow, facilitating the airflow from the first air inlet cavity 1611 through the through hole 1631 into the second air inlet cavity 1621 and finally into the atomization channel 1541.

[0052] In this embodiment, since the outer shell 110 is provided with a second air inlet 112 and the suction nozzle 120 is provided with a second air outlet 1212, a detection channel 193 is formed between the second air inlet 112 and the second air outlet 1212, and the airflow sensor 140 is arranged inside the outer shell 110 near the suction nozzle 120, and is located at the detection channel 193. In this way, when the user inhales the aerosol through the suction nozzle 120, the side of the airflow sensor 140 facing the second air inlet 112 is connected to the outside atmosphere through the second air inlet 112, and the gas on the side of the airflow sensor 140 close to the suction nozzle 120 is sucked out from the second air outlet 1212 to form a negative pressure. At this time, the airflow sensor 140 can detect the user's suction action by detecting the air pressure difference on both sides thereof. As described above, since the airflow sensor 140 is disposed near the suction nozzle 120 and the first air outlet 1211 and the second air outlet 1212 are located at different positions of the suction nozzle 120 and are not connected to each other, the influence of condensation on the airflow sensor 140 can be effectively reduced.

[0053] On this basis, the air inlet member 160 is arranged at the end of the atomizer assembly 150 away from the mouthpiece 120. The air inlet member 160 and the inner wall of the outer shell 110 jointly define a first air inlet cavity 1611 connected to the first air inlet port 111, and jointly define a second air inlet cavity 1621 connected to the atomization channel 1541 with the atomizer assembly 150, and a through hole 1631 is opened on the air inlet member 160 to connect the first air inlet cavity 1611 and the second air inlet cavity 1621. The through hole 1631 is connected to the atomization channel 1541 through the second air inlet cavity 1621, and the air inlet path is further optimized through the first air inlet cavity 1611. This makes up for the defects caused by the phase staggered setting mentioned in the relevant technology, that is, shortens the flow path of the airflow, so that the airflow at the first air inlet port 111 can directly pass through the atomization channel 1541, thereby making it easier and more labor-saving for the user to inhale the aerosol, thereby improving the user's user experience. At the same time, the first air inlet 111 does not need to be aligned with the atomization channel 1541 , thereby reducing the possibility of condensation liquid flowing out of the first air inlet 111 and affecting the user experience.

[0054] like Figure 2 、 Figure 7 and Figure 8 As shown, in one embodiment, the electronic atomization device 100 further includes an air regulating component 170, and the air regulating component 170 includes a sealing member 171 and a moving member 172. The sealing member 171 blocks one end of the first air inlet cavity 1611 close to the first air inlet port 111, and the sealing member 171 is respectively provided with a first air vent 1711 and a second air vent 1712 passing through it, and the first air vent 1711 and the second air vent 1712 are respectively connected to the first air inlet cavity 1611. The moving member 172 is located at the first air inlet port 111 and can move relative to the outer shell 110 along a preset direction Y, and the preset direction Y is perpendicular to the air inlet direction X of the atomization channel 1541, and the moving member 172 is respectively provided with a first air regulating hole 1721 and a second air regulating hole 1722 passing through it.

[0055] For example, the sealing member 171 may be an elastic component such as sealing silica gel, sealing rubber, etc. It should be noted that the air intake direction X and the axial direction of the electronic atomization device 100 are parallel to each other.

[0056] It can be understood that when the moving part 172 moves to the first preset position along the preset direction Y, the first air regulating hole 1721 is respectively connected to the first air inlet 111 and the first air vent 1711, and the second air regulating hole 1722 is respectively connected to the first air inlet 111 and the second air vent 1712. At this time, the electronic atomization device 100 enters the first working mode, and the air intake at the first air inlet 111 reaches the maximum. When the moving part 172 moves to the second preset position along the preset direction Y, the first air regulating hole 1721 is respectively connected to the first air inlet 111 and the first air vent 1711, and the second air regulating hole 1722 is connected to the first air inlet 111, and is not connected to the second air vent 1712. At this time, the electronic atomization device 100 enters the second working mode, and the air intake at the first air inlet 111 is inferior to that of the first working mode. When the moving part 172 moves to the third preset position along the preset direction Y, the first air regulating hole 1721 is not connected with the first air inlet 111 and the first air vent 1711 respectively, and the second air regulating hole 1722 is not connected with the first air inlet 111 and the second air vent 1712 respectively. At this time, the electronic atomization device 100 enters the shutdown mode, and the air intake at the first air inlet 111 is zero.

[0057] In this embodiment, the user can adjust the air intake volume at the first air inlet 111 by turning the movable member 172, so that the mouth feel of the aerosol can be adjusted, thereby improving the user experience.

[0058] like Figure 2 、 Figure 7 and Figure 8As shown, further, a plurality of first vent holes 1711 are provided, with two adjacent first vent holes 1711 spaced apart, and a second vent hole 1712 is distributed between each two adjacent first vent holes 1711. Each first vent hole 1711 is staggered with the atomization channel 1541, that is, each first vent hole 1711 does not at least partially overlap with the projection of the atomization channel 1541 in the axial direction of the electronic atomization device 100, and each second vent hole 1712 is staggered with the atomization channel 1541, that is, each second vent hole 1712 does not at least partially overlap with the projection of the atomization channel 1541 in the axial direction of the electronic atomization device 100. In this way, the condensed liquid in the atomization channel 1541 will be blocked by the sealing member 171 and is not likely to flow out of the first air inlet 111 along the first vent hole 1711 and the second vent hole 1712, thereby reducing the situation where the condensed liquid flows out of the outer shell 110 and affects the user experience.

[0059] Of course, for the above embodiment, the number of the first air vent 1711, the second air vent 1712, the first air adjustment hole 1721 and the second air adjustment hole 1722 can be one, two, three, four, etc., and no specific limitation is made to the number of the air vents and air adjustment holes.

[0060] like Figures 7 to 9 As shown, in one embodiment, the air inlet part 160 includes a first air inlet part 161, a second air inlet part 162 and a third air inlet part 163, the second air inlet part 162 is connected to the end of the atomizer assembly 150 away from the suction nozzle 120, and the second air inlet part 162 and the atomizer assembly 150 jointly define a second air inlet cavity 1621, the first air inlet part 161 is connected to the side of the second air inlet part 162 away from the atomizer assembly 150, the first air inlet part 161 and the inner wall of the outer shell 110 jointly define a first air inlet cavity 1611, the third air inlet part 163 is arranged between the first air inlet cavity 1611 and the second air inlet cavity 1621, and a plurality of through holes 1631 are opened, and two adjacent through holes 1631 are arranged at intervals.

[0061] Exemplarily, there are two through holes 1631, which are spaced apart from each other. Of course, the number of through holes 1631 can also be three, four, five, etc., which is not specifically limited here.

[0062] In this embodiment, when a user inhales an aerosol through the mouthpiece 120, airflow at the first air inlet 111 sequentially passes through the first air inlet cavity 1611, the through hole 1631, and the second air inlet cavity 1621 of the air inlet member 160 before entering the atomization channel 1541. Simultaneously, the side of the airflow sensor 140 facing the second air inlet 112 is connected to the outside atmosphere through the second air inlet 112. Air near the side of the airflow sensor 140 near the mouthpiece 120 is drawn out through the second air outlet 1212, creating a negative pressure. At this point, the airflow sensor 140 can detect the user's puffing action by detecting the pressure difference between the two sides.

[0063] like Figure 6 and Figure 8 As shown, further, each through hole 1631 is staggered with respect to the atomizing channel 1541. In this way, the condensed liquid formed by cooling in the atomizing channel 1541 will be blocked by the third air inlet portion 163 and will not easily flow out of the first air inlet 111 along the through hole 1631, thereby reducing the possibility of the condensed liquid flowing out of the outer shell 110 and affecting the user experience.

[0064] like Figure 9 As shown, further, a wire threading hole 1622 communicating with the second air inlet cavity 1621 is formed on the second air inlet portion 162 , and the wire threading hole 1622 is used to pass the wire harness 1542 of the atomizing assembly 150 .

[0065] In this embodiment, when assembling the atomizer assembly 150 and the air inlet 160, the wiring harness 1542 of the atomizer assembly 150 can be passed through the wire hole 1622, and then the wire hole 1622 can be sealed with glue to facilitate electrical connection between the atomizer assembly 150 and the control motherboard in the electronic atomizer device 100.

[0066] like Figure 8 、 Figure 9 and Figure 14 As shown, further, the air inlet part 160 also includes a sliding portion 164 and a clamping portion 165, which are respectively connected to the second air inlet portion 162, and the inner shell 151 has an end with an opening 1512, on which a guide portion 1515 and a limiting portion 1516 are respectively provided, and the sliding portion 164 is used to be slidably connected to the guide portion 1515.

[0067] Exemplarily, the engaging portion 165 is a buckle, and the limiting portion 1516 is a limiting groove. Of course, the engaging portion 165 can also be a slot, and the limiting portion 1516 can be a limiting buckle. In addition, the sliding portion 164 is a sliding groove, and the guide portion 1515 is a guide plate. Of course, the sliding portion 164 can also be a sliding plate, and the guide portion 1515 can be a guide groove.

[0068] In this embodiment, when the sliding portion 164 slides to a preset position along the guide portion 1515 , the engaging portion 165 engages with the limiting portion 1516 to limit the relative movement of the air inlet member 160 and the inner shell 151 , thereby facilitating the assembly of the inner shell 151 and the air inlet member 160 .

[0069] Of course, for the above embodiment, the air intake part 160 can also cancel the third air intake part 163, that is, the air intake part 160 includes a first air intake part 161 and a second air intake part 162, the second air intake part 162 is connected to the atomization component 150 and jointly defines a second air intake cavity 1621, the first air intake part 161 and the inner wall of the outer shell 110 jointly define a first air intake cavity 1611, and the first air intake cavity 1611 and the second air intake cavity 1621 are directly connected. No specific restrictions are made on the structure of the air intake part 160 here.

[0070] like Figures 2 to 4 As shown, in one embodiment, the detection channel 193 includes a gap 181 and a accommodating cavity 113, the electronic atomization device 100 also includes a charging interface part 180, the second air inlet 112 is a charging hole, the charging interface part 180 is arranged at the charging hole, and the above-mentioned gap 181 is formed between the charging interface part 180 and the edge of the charging hole, the outer shell 110 has the above-mentioned accommodating cavity 113, the accommodating cavity 113 is used to respectively accommodate the air inlet part 160 and the atomization assembly 150, and the accommodating cavity 113 is respectively connected to the gap 181 and the second air outlet 1212.

[0071] Exemplarily, the charging interface 180 may be a Type-C interface. Of course, the charging interface 180 may also be a USB interface, a Lightning interface, etc.

[0072] In this embodiment, when the user inhales the aerosol, one side of the airflow sensor 140 is connected to the outside atmosphere through the gap 181 and the second air inlet 112, and the gas on the other side of the airflow sensor 140 is sucked out from the second air outlet 1212 to form a negative pressure. At this time, the airflow sensor 140 can detect the user's inhalation action by detecting the air pressure difference on both sides thereof.

[0073] It is understandable that by using the charging hole as the second air inlet 112, the electronic atomization device 100 does not need to be equipped with a separate airflow detection port, thereby reducing production costs.

[0074] like Figure 4 and Figure 11As shown, in one embodiment, the detection channel 193 includes an installation cavity 131, and the electronic atomization device 100 also includes a mounting member 130. The mounting member 130 is arranged inside the outer shell 110. The mounting member 130 is arranged inside the outer shell 110 and is arranged on the outer peripheral side of the inner shell 151, and defines the above-mentioned installation cavity 131. The installation cavity 131 is respectively connected to the second air inlet 112 and the second air outlet 1212, and the airflow sensor 140 is sealed at the installation cavity 131.

[0075] In this embodiment, the installation of mounting member 130 facilitates the installation of airflow sensor 140. It will be appreciated that when a user inhales an aerosol, mounting member 130 seals and isolates the air path, allowing airflow sensor 140 within mounting cavity 131 to detect the user's aerosol inhalation by measuring the air pressure difference across the cavity.

[0076] like Figures 12 to 14 As shown, further, the atomizer assembly 150 includes: an inner shell 151, a first sealing element 152, a liquid storage element 153, an atomizer core 154 and a liquid guide element 155. The inner shell 151 has a liquid storage chamber 1511 and an opening 1512 connected to the liquid storage chamber 1511. The end of the inner shell 151 away from the opening 1512 is integrally connected to the mouthpiece 120. The mounting member 130 is provided on the outer peripheral side of the inner shell 151. The air intake member 160 is provided at the end of the inner shell 151 having the opening 1512. The first sealing element 152 blocks the end of the liquid storage chamber 1511 close to the opening 1512. The air intake member 160 is connected to the inner shell 151 to cover the opening 1512. The air intake member 160 and the first sealing element 152 jointly define a second air intake chamber 1621. The liquid storage element 153 is disposed within the liquid storage cavity 1511 and is used to store aerosol substrate. The atomizer core 154 has an atomization channel 1541. At least a portion of the atomizer core 154 is located within the liquid storage cavity 1511, and the atomizer core 154 is respectively inserted through the first sealing element 152 and the liquid storage element 153. The liquid guide element 155 is connected between the outer periphery of the atomizer core 154 and the liquid storage element 153 to guide the aerosol substrate into the atomization channel 1541.

[0077] For example, the first sealing element 152 may be a sealing silicone, sealing rubber, or other elastic component. The liquid storage element 153 may be a liquid-absorbing component such as liquid storage cotton or liquid storage fiber. The liquid conducting element 155 may be a liquid-absorbing component such as liquid conducting cotton or liquid conducting fiber.

[0078] It is understandable that when the user inhales through the mouthpiece 120, the airflow sensor 140 detects the user's inhalation action by detecting the air pressure difference on both sides thereof, and then triggers the atomization core 154 to heat the aerosol matrix introduced by the liquid guide element 155, thereby atomizing the aerosol matrix into an aerosol. The generated aerosol is discharged from the first air outlet 1211 through the atomization channel 1541 for the user to inhale.

[0079] In this embodiment, the end of the inner shell 151 away from the opening 1512 is integrally connected to the nozzle 120 , that is, the inner shell 151 and the nozzle 120 are formed into one piece, which can effectively improve the sealing effect and thus effectively reduce the possibility of leakage of the aerosol matrix.

[0080] like Figures 10 to 13 As shown, further, the detection channel 193 includes a first air hole 132 and a second air hole 1514, and a mounting groove 1513 is provided on the outer peripheral side of the end of the inner shell 151 close to the suction nozzle 120, and at least a part of the mounting member 130 is arranged in the mounting groove 1513, and a first air hole 132 connected to the mounting cavity 131 is provided on the mounting member 130, and a second air hole 1514 is provided on the inner shell 151, and the second air hole 1514 is respectively connected to the first air hole 132 and the second air outlet 1212.

[0081] It can be understood that when the user inhales the aerosol, one side of the airflow sensor 140 is connected to the outside atmosphere through the second air inlet 112, and the gas on the other side of the airflow sensor 140 is inhaled by the user from the second air outlet 1212 through the first air hole 132 and the second air hole 1514 to form a negative pressure. At this time, the airflow sensor 140 can detect the user's suction action by detecting the air pressure difference on both sides thereof, thereby triggering the atomization core 154 to atomize the aerosol matrix to form an aerosol.

[0082] In this embodiment, since the airflow sensor 140 is located near the nozzle 120 and the first air outlet 1211 and the second air outlet 1212 are not connected to each other, the effect of condensation in the atomization channel 1541 on the airflow sensor 140 can be effectively reduced. In addition, the provision of the mounting groove 1513 facilitates the installation of the mounting member 130 on the outer periphery of the inner housing 151.

[0083] like Figures 12 to 14As shown, further, the detection channel 193 includes an inner cavity 1213 and an extension channel 1561, the atomizer assembly 150 further includes a second sealing element 156, the nozzle 120 includes a nozzle body 121 and an air outlet pipe 122, the nozzle body 121 is respectively provided with a first air outlet 1211 and a second air outlet 1212, the nozzle body 121 defines the inner cavity 1213, the second sealing element 156 is sealed at one end of the liquid storage chamber 1511 close to the inner cavity 1213, and one end of the air outlet pipe 122 is connected to the first The edge of the air outlet 1211 is connected, and the part of the air outlet pipe 122 away from the second air outlet 1212 is passed through the second sealing element 156 so that the interior of the air outlet pipe 122 is connected with the atomization channel 1541 and the first air outlet 1211 respectively. The outer peripheral side of the second sealing element 156 and the cavity wall of the liquid storage cavity 1511 jointly define an extension channel 1561, and the extension channel 1561 is connected with the second air hole 1514 and the inner cavity 1213 respectively, and the second air outlet 1212 is connected with the inner cavity 1213.

[0084] For example, the second sealing element 156 may be an elastic component such as sealing silica gel or sealing rubber.

[0085] In this embodiment, because the second sealing element 156 blocks the end of the liquid storage chamber 1511 near the inner cavity 1213, the inner cavity 1213 can communicate with the second air outlet 1212 and the extension channel 1561 respectively, but is not connected to the liquid storage chamber 1511. As a result, the condensate in the atomization channel 1541 is less likely to affect the airflow sensor 140, thereby improving the airflow detection accuracy of the airflow sensor 140.

[0086] like Figure 4 、 Figure 8 and Figure 9 As shown, further, the electronic atomization device 100 also includes a first liquid injection plug 191 and a second liquid injection plug 192, and the air inlet part 160 is respectively provided with a first liquid injection hole 1623 and a second liquid injection hole 1624 passing through it, the first liquid injection hole 1623 and the second liquid injection hole 1624 are respectively connected to the liquid storage chamber 1511, the first liquid injection plug 191 is sealed at the first liquid injection hole 1623, and the second liquid injection plug 192 is sealed at the second liquid injection hole 1624.

[0087] Exemplarily, the liquid injection plug may be an elastic component such as sealing silica gel or sealing rubber.

[0088] In this embodiment, the provision of the first injection hole 1623 and the second injection hole 1624 facilitates filling the liquid storage chamber 1511 with the aerosol matrix. After the aerosol matrix is ​​injected, the first injection hole 1623 is sealed with the first injection plug 191, and the second injection hole 1624 is sealed with the second injection plug 192.
