本申请实施例提供的电子雾化装置100包括外部主体(或称壳体)内的数个部件。外部主体的总体设计可变化，且可以限定电子雾化装置100的总体尺寸和形状的外部主体的型式或配置可变化。通常，外部主体可由单个一体式壳体形成，或可由两个或更多个可分离的壳体形成；其中，一体式壳体包括由多个部件固定连接而成的结构，其不可拆卸，从而成为一体式壳体。可选地，外部主体可由诸如不锈钢、铝之类的金属或合金形成，其它适合的材料可包括各种塑料(例如，聚碳酸酯)、金属电镀塑料(metal-plating over plastic)、陶瓷等等。The electronic atomization device 100 provided in the embodiment of the present application includes several components within an external body (or shell). The overall design of the external body may vary, and the type or configuration of the external body that can define the overall size and shape of the electronic atomization device 100 may vary. Typically, the external body may be formed by a single integral shell, or may be formed by two or more separable shells; wherein the integral shell includes a structure formed by a plurality of components fixedly connected, which is not removable, thereby becoming an integral shell. Optionally, the external body may be formed of a metal or alloy such as stainless steel or aluminum, and other suitable materials may include various plastics (e.g., polycarbonate), metal-plating over plastic, ceramics, and the like.

在图1所示的具体实施例中，电子雾化装置100包括壳体10，壳体10基本限定电子雾化装置100的外表面。电子雾化装置100限定有纵向方向Y并具有沿纵向方向Y相对的近端110和远端120。在使用中，近端110是靠近用户抽吸的一端，远端120是远离用户的一端。In the specific embodiment shown in FIG1 , the electronic atomization device 100 includes a housing 10 that generally defines an outer surface of the electronic atomization device 100. The electronic atomization device 100 defines a longitudinal direction Y and has a proximal end 110 and a distal end 120 that are opposed along the longitudinal direction Y. In use, the proximal end 110 is the end closer to the user for inhalation, and the distal end 120 is the end away from the user.

在一些实施方式中，电子雾化装置100的壳体10可以进一步包括第一壳体、第二壳体和第三壳体。第一壳体沿纵向方向Y靠近近端110布置，并界定外壳的近端110；第三壳体沿纵向方向Y靠近远端120布置，并界定外壳的远端120。第一壳体、第二壳体和第三壳体基本是同轴布置的，使得第一壳体和第三壳体的至少部分可以伸入或嵌入至第二壳体内固定。具体地，第一壳体内是存储液体基质、并加热雾化的加热空间；第二壳体和第三壳体内为电子空间，其中，第二壳体内安装和存储有用于为电子雾化装置100供电的电子器件，第三壳体内安装和存储有用于控制电子雾化装置100供电的电子器件。为了易于描述，以下将电子雾化装置100的外部主体视为由单个一体式的壳体10形成，然而其并非构成对本申请的限制。In some embodiments, the shell 10 of the electronic atomization device 100 may further include a first shell, a second shell, and a third shell. The first shell is arranged near the proximal end 110 along the longitudinal direction Y and defines the proximal end 110 of the shell; the third shell is arranged near the distal end 120 along the longitudinal direction Y and defines the distal end 120 of the shell. The first shell, the second shell, and the third shell are basically coaxially arranged so that at least part of the first shell and the third shell can be extended into or embedded in the second shell for fixation. Specifically, the first shell contains a heating space for storing the liquid matrix and heating the atomization; the second shell and the third shell contain electronic spaces, wherein the second shell is equipped with and stores electronic devices for powering the electronic atomization device 100, and the third shell is equipped with and stores electronic devices for controlling the power supply of the electronic atomization device 100. For ease of description, the outer body of the electronic atomization device 100 is regarded as being formed by a single integral shell 10 below, but it does not constitute a limitation to the present application.

The shell 10 defines a liquid storage chamber 101 for storing a liquid matrix. Specifically, the shell 10 accommodates the sealing bracket 20, the atomization assembly 30 and the base 40. The sealing bracket 20 is at least partially used to seal the liquid storage chamber 101 and define at least part of the boundary of the liquid storage chamber 101. The atomization assembly 30 is used to receive the liquid matrix in the liquid storage chamber 101 and atomize it to generate an aerosol. The sealing bracket 20 is surrounded or defined by an atomization chamber 211, and the atomization assembly 30 is accommodated and retained in the atomization chamber 211. The conductive electrode 60 is arranged on the base 40 and is electrically connected to the atomization assembly 30.

在一些具体实施方式中，电子雾化装置100进一步包括电芯51、控制电路板(未标示)、电连接端子(未标示)和气流传感器52，电连接端子可与导电电极60电连接。当用户使用电子雾化装置100抽吸时，气流传感器感应到内部的气压变化，向控制电路板发送感应信号，使得控制电路板根据感应信号控制电芯51通过电连接端子对导电电极60提供电能。电子雾化装置100还可以包括电池支架(未标示)等其它元件，本申请对此不做限制。In some specific embodiments, the electronic atomization device 100 further includes a battery cell 51, a control circuit board (not shown), an electrical connection terminal (not shown), and an airflow sensor 52, which can be electrically connected to the conductive electrode 60. When a user uses the electronic atomization device 100 to inhale, the airflow sensor senses the internal air pressure change and sends a sensing signal to the control circuit board, which controls the battery cell 51 to provide electrical energy to the conductive electrode 60 through the electrical connection terminal based on the sensing signal. The electronic atomization device 100 may also include other components such as a battery holder (not shown), which are not limited in this application.

图4是如图1所示的电子雾化装置100去掉壳体10、电芯51和气流传感器52后的结构示意图。图5是如图4所示的电子雾化装置100部分沿C-C方向的截面结构示意图，该C-C方向可与图1中的A-A方向一致。图6是如图4所示的电子雾化装置100部分沿D-D方向的截面结构示意图，该D-D方向可与图1中的B-B方向一致。Figure 4 is a schematic diagram of the structure of the electronic atomization device 100 shown in Figure 1, excluding the housing 10, battery cell 51, and airflow sensor 52. Figure 5 is a schematic diagram of the cross-sectional structure of the electronic atomization device 100 shown in Figure 4, taken along the C-C direction, which may be consistent with the A-A direction in Figure 1. Figure 6 is a schematic diagram of the cross-sectional structure of the electronic atomization device 100 shown in Figure 4, taken along the D-D direction, which may be consistent with the B-B direction in Figure 1.

如图4所示，密封支架20包括相互连接的顶壁和环壁，密封支架20外表面上设有从顶壁延伸至环壁的下液槽27。下液槽27位于顶壁的部分与储液腔101连通，且密封支架20在下液槽27的底部开设有进液口201，使得储液腔101内的液体基质可以通过下液槽27流向进液口201，箭头L1示出液体基质从储液腔101流入进液口201的路径。在一些实施例中，密封支架20由柔性的软胶材料制成，例如硅胶、橡胶或热塑性弹性体，使得雾化组件30可以通过过盈配合的方式固定在进液口201处。As shown in FIG4 , the sealing bracket 20 includes a top wall and an annular wall connected to each other. A lower liquid groove 27 extending from the top wall to the annular wall is provided on the outer surface of the sealing bracket 20. The portion of the lower liquid groove 27 located on the top wall communicates with the liquid storage chamber 101, and the sealing bracket 20 has a liquid inlet 201 at the bottom of the lower liquid groove 27, allowing the liquid matrix in the liquid storage chamber 101 to flow through the lower liquid groove 27 to the liquid inlet 201. Arrow L1 shows the path of the liquid matrix flowing from the liquid storage chamber 101 into the liquid inlet 201. In some embodiments, the sealing bracket 20 is made of a flexible soft rubber material, such as silicone, rubber, or a thermoplastic elastomer, so that the atomizer assembly 30 can be fixed to the liquid inlet 201 by an interference fit.

根据使用的情形，如图12所示，雾化组件30包括多孔体31和结合于所述多孔体31上的加热元件32。多孔体31平行于电子雾化装置100的纵向方向Y布置，并具有相背的第一侧表面311和第二侧表面312。第一侧表面311用于接收来自于储液腔101的液体基质，加热元件32结合在第二侧表面312上用于加热雾化所述液体基质。雾化组件30按照第二侧表面312位于或裸露于雾化腔室211的取向安装在密封支架20内。第一侧表面311朝向进液口201并流体连通储液腔101，使得储液腔101中的液体基质可以如图4和图5中的L1所示经过进液口201流向第一侧表面311，并通过多孔体31的内部微孔结构流向第二侧表面312。当结合在第二侧表面312上的加热元件32完成对多孔体31内的至少部分液体基质的加热雾化后，产生的气溶胶将从第二侧表面312上释放并存储在雾化腔室211内。如上设计可以实现侧面进液，从而提高对多孔体31供液的均匀性。According to the usage scenario, as shown in Figure 12, the atomization assembly 30 includes a porous body 31 and a heating element 32 coupled to the porous body 31. The porous body 31 is arranged parallel to the longitudinal direction Y of the electronic atomization device 100, and has a first side surface 311 and a second side surface 312 opposite to each other. The first side surface 311 is used to receive the liquid matrix from the liquid storage chamber 101, and the heating element 32 is coupled to the second side surface 312 for heating and atomizing the liquid matrix. The atomization assembly 30 is installed in the sealing bracket 20 in an orientation in which the second side surface 312 is located or exposed in the atomization chamber 211. The first side surface 311 faces the liquid inlet 201 and is fluidically connected to the liquid storage chamber 101, so that the liquid matrix in the liquid storage chamber 101 can flow through the liquid inlet 201 to the first side surface 311 as shown in L1 in Figures 4 and 5, and flow to the second side surface 312 through the internal microporous structure of the porous body 31. After the heating element 32 coupled to the second side surface 312 completes heating and atomizing at least a portion of the liquid matrix within the porous body 31, the generated aerosol is released from the second side surface 312 and stored within the atomization chamber 211. This design allows for side liquid inlet, thereby improving the uniformity of liquid supply to the porous body 31.

可选地，加热元件32采用不锈钢、镍铬合金、铁铬铝合金或金属钛等材质，优选采用通过具有导电性的原材料粉末与印刷助剂混合成浆料后，按照适合的图案印刷后烧结的方式形成在第二侧表面312上，从而使其全部或绝大部分表面都与第二侧表面312紧密结合，具有雾化效率高、热量损失少、防干烧或大大的减少干烧等效果。加热元件32可以采用多种结构形式，可以是结合于第二侧表面312上的形成有特定图案的片状发热体，或者是发热网、发热丝螺旋形成的盘状发热体、发热膜等其它形式；例如该特定图案可以是蛇形蜿蜒形状。Optionally, the heating element 32 is made of stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy or titanium, and is preferably formed on the second side surface 312 by mixing conductive raw material powder with a printing aid into a slurry, printing it according to a suitable pattern, and then sintering it, so that all or most of its surface is tightly bonded to the second side surface 312, with the effects of high atomization efficiency, low heat loss, and preventing dry burning or greatly reducing dry burning. The heating element 32 can adopt a variety of structural forms, and can be a sheet-like heating element with a specific pattern formed on the second side surface 312, or a heating mesh, a disc-shaped heating element formed by a heating wire spiral, a heating film, or other forms; for example, the specific pattern can be a serpentine shape.

在一些具体实施方式中，密封支架20的顶壁设有出气口202。如图2和图3所示，壳体10内设置用于限定导雾通道的中空管102。出气口202的一端连接于中空管102，另一端连接于雾化腔室211。同时，中空管102远离出气口202的一端具有吸食口103，所述吸食口103与导雾通道连通。中空管102用于将雾化腔室211内储存的气溶胶经导雾通道从吸食口103导出供用户抽吸。In some embodiments, the top wall of the sealing bracket 20 is provided with an air outlet 202. As shown in Figures 2 and 3, a hollow tube 102 is provided within the housing 10 to define a mist guide channel. One end of the air outlet 202 is connected to the hollow tube 102, and the other end is connected to the atomization chamber 211. Furthermore, the end of the hollow tube 102, away from the air outlet 202, has an inhalation port 103, which is connected to the mist guide channel. The hollow tube 102 is used to guide the aerosol stored in the atomization chamber 211 through the mist guide channel and out of the inhalation port 103 for inhalation by the user.

如图5和图6所示，基座40上设有进气口45，进气口45一端连通雾化腔室211，另一端连通外部空气。外部空气的至少部分可以从进气口45进入到雾化腔室211内，携带由多孔体31加热雾化产生的气溶胶通过出气口202流出雾化腔室211，并经中空管102所限定的导雾通道流向吸食口103供用户吸食。As shown in Figures 5 and 6, the base 40 is provided with an air inlet 45, one end of which is connected to the atomization chamber 211 and the other end is connected to the outside air. At least a portion of the outside air can enter the atomization chamber 211 through the air inlet 45, carrying the aerosol generated by the heating and atomization of the porous body 31, out of the atomization chamber 211 through the air outlet 202, and then flowing through the aerosol guide channel defined by the hollow tube 102 to the inhalation port 103 for inhalation by the user.

在一些实施例中，由于软胶材料的支撑力不足，密封支架20与多孔体31之间的密封性能较差，液体基质可能通过多孔体31与密封支架20之间的间隙渗入雾化腔室211造成漏液。如图2所示，针对于此处的漏液问题，电子雾化装置100可以进一步包括支撑部111，密封支架20的至少部分位于中空管102与支撑部111之间。支撑部111具体为硬性件，用于与软性的密封支架20配合提供朝向多孔体31方向上的支撑，以将密封支架20的一部分按压在多孔体31的第一侧表面311上，进而在第一侧表面311一侧实现密封硬支撑，提升多孔体31处密封可靠性。具体而言，支撑部111定位于密封支架20背离多孔体31的一侧。可选地，支撑部111自中空管102朝向密封支架20延伸，且支撑部111与壳体10的内壁之间保持间距。支撑部111还可以设置在壳体10的其它位置，例如壳体10的内壁或中空管102上，本申请对此不做限制。In some embodiments, due to insufficient supporting force of the soft rubber material, the sealing performance between the sealing bracket 20 and the porous body 31 is poor, and the liquid matrix may penetrate into the atomization chamber 211 through the gap between the porous body 31 and the sealing bracket 20, causing leakage. As shown in Figure 2, in response to the leakage problem here, the electronic atomization device 100 may further include a support portion 111, and at least part of the sealing bracket 20 is located between the hollow tube 102 and the support portion 111. The support portion 111 is specifically a hard part, which is used to cooperate with the soft sealing bracket 20 to provide support in the direction toward the porous body 31, so as to press a part of the sealing bracket 20 on the first side surface 311 of the porous body 31, thereby realizing sealing hard support on the side of the first side surface 311, and improving the sealing reliability at the porous body 31. Specifically, the support portion 111 is positioned on the side of the sealing bracket 20 away from the porous body 31. Optionally, the support portion 111 extends from the hollow tube 102 toward the sealing bracket 20, and a distance is maintained between the support portion 111 and the inner wall of the housing 10. The support portion 111 can also be provided at other locations of the housing 10, such as the inner wall of the housing 10 or the hollow tube 102, and this application does not limit this.

Fig. 8 is a schematic diagram of the exploded structure of the electronic atomization device 100 shown in Fig. 4 from another perspective.

如图7和图8所示，密封支架20在与第二侧表面312相对且间隔的侧壁上开设有容置槽203，用于安装多孔吸液元件2030。可选地，多孔吸液元件2030采用棉等材料，用于吸附从出气口202附近的槽孔2021渗入雾化腔室211的冷凝液，从而避免漏液。As shown in Figures 7 and 8, the sealing bracket 20 has a receiving groove 203 on a side wall opposite and spaced from the second side surface 312 for mounting a porous liquid-absorbing element 2030. Optionally, the porous liquid-absorbing element 2030 is made of a material such as cotton and is used to absorb condensed liquid that seeps into the atomization chamber 211 through the slots 2021 near the air outlet 202, thereby preventing liquid leakage.

请参阅图2至图6，R1示出了外部空气进入电子雾化装置100后的一条气流路径，即外部空气将存储在雾化腔室211中的气溶胶通过中空管102导出的气流路径。如图2和图3所示，电子雾化装置100在远端120开设有进气通道121，进气通道121与进气口45保持连通，使得用户抽吸时外部空气可以从进气通道121进入电子雾化装置100，并沿电子雾化装置100的纵向方向Y通过电芯51和壳体10之间的缝隙流通至进气口45处。具体地，进气口45、雾化腔室211和出气口202沿R1依次排列，且多孔吸液元件2030、雾化腔室211和多孔体31沿与R1垂直的方向并排布置，使得R1自进气口45至出气口202的部分从多孔吸液元件2030与多孔体31之间穿过，且第二侧表面312基本平行于R1。即，在本申请的实施例中，雾化模式为侧向雾化。值得注意的是，R1进入进气口45后呈直通道且穿过雾化腔室211，上述各部分的排布逻辑可以避免多孔体31对R1形成阻挡，从而减少气流流动死角区，有效缩短气溶胶到达吸食口103的路径，保证气溶胶能够以更好的口感进入用户口中，显著提升用户体验。Referring to Figures 2 to 6 , R1 illustrates an airflow path after external air enters the electronic atomization device 100, i.e., the airflow path by which the external air guides the aerosol stored in the atomization chamber 211 through the hollow tube 102. As shown in Figures 2 and 3 , the electronic atomization device 100 has an air inlet channel 121 at the distal end 120. The air inlet channel 121 is connected to the air inlet 45 , allowing external air to enter the electronic atomization device 100 through the air inlet channel 121 when a user inhales, and then flow along the longitudinal direction Y of the electronic atomization device 100 through the gap between the battery cell 51 and the housing 10 to the air inlet 45 . Specifically, the air inlet 45, the atomizing chamber 211, and the air outlet 202 are arranged in sequence along R1, and the porous liquid-absorbing element 2030, the atomizing chamber 211, and the porous body 31 are arranged side by side in a direction perpendicular to R1, so that the portion of R1 from the air inlet 45 to the air outlet 202 passes between the porous liquid-absorbing element 2030 and the porous body 31, and the second side surface 312 is substantially parallel to R1. That is, in the embodiment of the present application, the atomization mode is lateral atomization. It is worth noting that after entering the air inlet 45, R1 presents a straight channel and passes through the atomizing chamber 211. The arrangement logic of the above-mentioned parts can avoid the porous body 31 from blocking R1, thereby reducing the dead angle area of airflow flow, effectively shortening the path of the aerosol to the inhalation port 103, ensuring that the aerosol can enter the user's mouth with a better taste, and significantly improving the user experience.

图9是如图1所示的电子雾化装置100中基座40的结构示意图。图10是如图1所示的电子雾化装置100中密封支架20的结构示意图。Fig. 9 is a schematic structural diagram of the base 40 in the electronic atomization device 100 shown in Fig. 1. Fig. 10 is a schematic structural diagram of the sealing bracket 20 in the electronic atomization device 100 shown in Fig. 1.

如图9所示，基座40包括导气部41。导气部41被构造成纵长的柱状或针状或杆状，其可设置在基座40上或属于基座40的一部分。如图10所示，密封支架20内布置有用于收容导气部41的至少一部分的孔22。通过将导气部41插设在孔22中，密封支架20与基座40可以实现固定连接。参考图4，导气部41的至少一部分穿过密封支架20的顶壁至储液腔101，并具有裸露于储液腔101的裸露区段。As shown in Figure 9, the base 40 includes an air guide portion 41. The air guide portion 41 is configured to be elongated in the shape of a column, needle, or rod, and may be provided on the base 40 or be a part of the base 40. As shown in Figure 10, a hole 22 for accommodating at least a portion of the air guide portion 41 is provided in the sealing bracket 20. By inserting the air guide portion 41 into the hole 22, the sealing bracket 20 and the base 40 can be fixedly connected. Referring to Figure 4, at least a portion of the air guide portion 41 passes through the top wall of the sealing bracket 20 to the liquid storage chamber 101, and has an exposed section exposed to the liquid storage chamber 101.

在一些具体实施方式中，密封支架20采用柔性材质，使得密封支架20的至少一部分可以在壳体10和基座40之间提供周向密封连接，从而防止储液腔101内的液体基质泄露。如图4所示，密封支架20的侧壁环设有密封筋23，密封筋23可以弹性压持于壳体10的内壁，以实现密封支架20与壳体10间的密封贴合。在可选的示例中，密封支架20的侧壁还可以环设有密封面24，所述密封面24与壳体10的内壁保持密封接合。In some embodiments, the sealing bracket 20 is made of a flexible material, so that at least a portion of the sealing bracket 20 can provide a circumferentially sealed connection between the housing 10 and the base 40, thereby preventing leakage of the liquid matrix within the liquid storage chamber 101. As shown in FIG4 , the sidewall of the sealing bracket 20 is provided with a sealing rib 23, which can be elastically pressed against the inner wall of the housing 10 to achieve a sealed fit between the sealing bracket 20 and the housing 10. In an optional example, the sidewall of the sealing bracket 20 can also be provided with a sealing surface 24, which maintains a sealing engagement with the inner wall of the housing 10.

在一些实施例中，进一步参阅图9和图10，基座40包括安装部42和自安装部42朝密封支架20延伸的环形壁43。密封支架20背离储液腔101的下端26开设有环形槽25，通过将环形壁43插设在环形槽25内，基座40至少部分从密封支架20的下端26伸入至密封支架20内，使得刚性的基座40可以从内部对柔性的密封支架20进行支撑，从而防止密封支架20变形。基座40上开设有电极插孔44，电子雾化装置100的导电电极60对应插设在电极插孔44中。其中，导电电极60的一端与电连接端子连接，另一端延伸至雾化腔室211内与多孔体31的第二侧表面312上的加热元件32抵接，实现雾化组件30与电芯51电连接，进而在通电条件下实现对液体基质进行加热雾化，以产生供用户使用的气溶胶。In some embodiments, further referring to Figures 9 and 10, the base 40 includes a mounting portion 42 and an annular wall 43 extending from the mounting portion 42 toward the sealing bracket 20. The lower end 26 of the sealing bracket 20 facing away from the liquid storage chamber 101 is provided with an annular groove 25. By inserting the annular wall 43 into the annular groove 25, the base 40 at least partially extends from the lower end 26 of the sealing bracket 20 into the sealing bracket 20, so that the rigid base 40 can support the flexible sealing bracket 20 from the inside, thereby preventing the sealing bracket 20 from deforming. The base 40 is provided with an electrode socket 44, and the conductive electrode 60 of the electronic atomization device 100 is correspondingly inserted into the electrode socket 44. Among them, one end of the conductive electrode 60 is connected to the electrical connection terminal, and the other end extends into the atomization chamber 211 and abuts against the heating element 32 on the second side surface 312 of the porous body 31, thereby realizing the electrical connection between the atomization component 30 and the battery core 51, and then heating and atomizing the liquid matrix under power-on conditions to generate an aerosol for the user.

在本申请的实施例中，电子雾化装置100进一步包括换气通道，其一端连通储液腔101，另一端连通外部空气，提供空气沿电子雾化装置的纵向方向Y穿过密封支架20进入储液腔101的通道路径，从而使得电子雾化装置100能够通过换气通道实现对储液腔101的换气功能。In an embodiment of the present application, the electronic atomization device 100 further includes a ventilation channel, one end of which is connected to the liquid storage chamber 101 and the other end is connected to the external air, providing a channel path for air to pass through the sealing bracket 20 along the longitudinal direction Y of the electronic atomization device and enter the liquid storage chamber 101, so that the electronic atomization device 100 can realize the ventilation function of the liquid storage chamber 101 through the ventilation channel.

可以理解的是，在电子雾化装置100的使用过程中，雾化组件30不断消耗储液腔101内液体基质，使得储液腔101内的气压持续降低，导致储液腔101内部与外部之间产生气压差。储液腔101内的气压失衡可能造成第一侧表面311无法正常吸收液体基质进入多孔体31内部，也可能造成雾化腔室211内的空气通过多孔体31反渗到储液腔101，在第一侧表面311发生气液接触形成气泡阻塞液体基质进入多孔体31内部。因此，为了缓解或消除储液腔101内外的气压差，所述换气通道提供空气进入储液腔101的路径，用于平衡储液腔101内外气压差，避免由于下液不畅导致多孔体31干烧的问题发生。It is understandable that during the use of the electronic atomization device 100, the atomization component 30 continuously consumes the liquid matrix in the liquid storage chamber 101, causing the air pressure in the liquid storage chamber 101 to continue to decrease, resulting in an air pressure difference between the inside and outside of the liquid storage chamber 101. The imbalance of air pressure in the liquid storage chamber 101 may cause the first side surface 311 to be unable to normally absorb the liquid matrix into the porous body 31, and may also cause the air in the atomization chamber 211 to reversely osmosis into the liquid storage chamber 101 through the porous body 31, and gas-liquid contact occurs on the first side surface 311 to form bubbles that block the liquid matrix from entering the porous body 31. Therefore, in order to alleviate or eliminate the air pressure difference between the inside and outside of the liquid storage chamber 101, the ventilation channel provides a path for air to enter the liquid storage chamber 101, which is used to balance the air pressure difference inside and outside the liquid storage chamber 101, and avoid the problem of dry burning of the porous body 31 due to poor liquid discharge.

在一些实施方式中，换气通道靠近储液腔101一侧的端口与第一侧表面311之间保持间距，以防止外部补充进入储液腔101的空气所产生的换气气泡从所述端口逸出时聚集在第一侧表面311附近阻碍吸液。In some embodiments, a distance is maintained between the port of the ventilation channel close to the liquid storage chamber 101 and the first side surface 311 to prevent ventilation bubbles generated by external air entering the liquid storage chamber 101 from escaping from the port and gathering near the first side surface 311 to hinder liquid suction.

在本申请的实施例中，参阅图11所示，换气通道包括第一通道部分、连接通道部分和第二通道部分。其中，第一通道部分靠近并连通储液腔101，其具体实现为包括第一凹槽410，第一凹槽410远离储液腔101的一端连通于所述连接通道部分。连接通道部分沿垂直于电子雾化装置100纵向方向Y的横向方向X布置且至少部分是弧形弯曲的，其具体实现为包括开设在密封支架20上的横向槽430；第二通道部分平行于电子雾化装置100的纵向方向Y布置，自密封支架20的下端26延伸至所述连接通道部分，其具体实现为包括开设在密封支架20上的纵向孔420。In an embodiment of the present application, referring to FIG11 , the ventilation channel includes a first channel portion, a connecting channel portion, and a second channel portion. The first channel portion is close to and connected to the liquid storage chamber 101, and is specifically implemented as including a first groove 410, and one end of the first groove 410 away from the liquid storage chamber 101 is connected to the connecting channel portion. The connecting channel portion is arranged along a transverse direction X perpendicular to the longitudinal direction Y of the electronic atomization device 100 and is at least partially arc-shaped, and is specifically implemented as including a transverse groove 430 provided on the sealing bracket 20; the second channel portion is arranged parallel to the longitudinal direction Y of the electronic atomization device 100, extending from the lower end 26 of the sealing bracket 20 to the connecting channel portion, and is specifically implemented as including a longitudinal hole 420 provided on the sealing bracket 20.

在图11所示的实施例中，连接通道部分将第一通道部分和第二通道部分连通。具体地，第一凹槽410远离储液腔101的一端终止于横向槽430，横向槽430围着导气部41外周延伸且大致呈周向约90°圆弧弯曲；纵向孔420的一端连通横向槽430，另一端作为换气通道的进气端口延伸至密封支架20的下端26。在一些具体的实施方式中，所述换气端口不限于孔状，其能够可选地作为环形槽25的至少部分。在密封支架20与基座40固定连接的情况下，即当环形壁43插入环形槽25时，从进气口45流入的空气可以通过环形槽25与环形壁43之间的间隙进入换气通道的第二通道部分。In the embodiment shown in Figure 11, the connecting channel portion connects the first channel portion and the second channel portion. Specifically, the end of the first groove 410 away from the liquid storage chamber 101 ends at a transverse groove 430, which extends around the outer periphery of the air guide portion 41 and is roughly curved in a circumferential arc of about 90 degrees; one end of the longitudinal hole 420 is connected to the transverse groove 430, and the other end extends to the lower end 26 of the sealing bracket 20 as an air inlet port of the ventilation channel. In some specific embodiments, the ventilation port is not limited to a hole shape, and it can optionally serve as at least a part of the annular groove 25. When the sealing bracket 20 is fixedly connected to the base 40, that is, when the annular wall 43 is inserted into the annular groove 25, the air flowing in from the air inlet 45 can enter the second channel portion of the ventilation channel through the gap between the annular groove 25 and the annular wall 43.

在一些具体实施方式中，第一凹槽410可以开设在导气部41的外表面，即导气部41的外周的至少部分向内凹陷，与孔22的内表面之间形成间隙。其中，第一凹槽410的一端延伸至导气部41的裸露区段并连通储液腔101，使得所述间隙作为第一通道部分为储液腔101换气。In some specific embodiments, the first groove 410 can be formed on the outer surface of the air guide portion 41, that is, at least a portion of the outer periphery of the air guide portion 41 is recessed inward, forming a gap between the inner surface of the hole 22. One end of the first groove 410 extends to the exposed section of the air guide portion 41 and communicates with the liquid storage chamber 101, so that the gap serves as a first channel portion for ventilating the liquid storage chamber 101.

在另一些具体实施方式中，第一凹槽410可以形成于孔22的与导气部41接触的内表面，即第一凹槽410开设在柔性材料上。第一凹槽410的一端延伸至密封支架20的顶壁并连通储液腔101，由导气部41的外表面与孔22的内表面的第一凹槽410配合形成第一通道部分，以实现为储液腔101换气。In other embodiments, the first groove 410 can be formed on the inner surface of the hole 22 that contacts the air guide portion 41, that is, the first groove 410 is formed in the flexible material. One end of the first groove 410 extends to the top wall of the sealing bracket 20 and connects to the liquid storage chamber 101. The outer surface of the air guide portion 41 cooperates with the first groove 410 on the inner surface of the hole 22 to form a first channel portion to achieve ventilation of the liquid storage chamber 101.

如图11所示，第一通道部分平行于所述纵向方向Y且与第二通道部分相对错开布置，使得第一通道部分、第二通道部分和连接通道部分配合实现非直线的换气通道。因此，当液体基质从储液腔101经由第一凹槽410进入换气通道时，至少一部分液体基质可以保持在换气通道中，而非直接沿第一凹槽410、横向槽430和纵向孔420的顺序通过换气通道流出。可选地，横向槽430可以具有毛细结构，纵向孔420也可以具有毛细结构。As shown in Figure 11, the first channel portion is parallel to the longitudinal direction Y and is staggered relative to the second channel portion, so that the first channel portion, the second channel portion, and the connecting channel portion cooperate to form a non-linear ventilation channel. Therefore, when the liquid matrix enters the ventilation channel from the liquid storage chamber 101 via the first groove 410, at least a portion of the liquid matrix can be retained in the ventilation channel, rather than flowing directly out of the ventilation channel along the order of the first groove 410, the transverse groove 430, and the longitudinal hole 420. Optionally, the transverse groove 430 can have a capillary structure, and the longitudinal hole 420 can also have a capillary structure.

值得注意的是，换气通道沿电子雾化装置100的纵向方向Y绕过雾化腔室211，和/或与雾化腔室211彼此隔离。在另一些可选的实施例中，换气通道布置在密封支架20的内壁上。具体地，换气通道为形成在密封支架20内的导气通孔，导气通孔远离储液腔101的一端作为换气通道的进气端口延伸至密封支架20的下端26并通过环形槽25与环形壁43之间的间隙和进气口45保持连通，提供外部空气进入储液腔101的通道路径。It is worth noting that the ventilation channel bypasses the atomization chamber 211 along the longitudinal direction Y of the electronic atomization device 100, and/or is isolated from the atomization chamber 211. In other optional embodiments, the ventilation channel is arranged on the inner wall of the sealing bracket 20. Specifically, the ventilation channel is an air-guiding through hole formed in the sealing bracket 20. The end of the air-guiding through hole away from the liquid storage chamber 101 serves as the air inlet port of the ventilation channel and extends to the lower end 26 of the sealing bracket 20 and maintains communication with the air inlet 45 through the gap between the annular groove 25 and the annular wall 43, providing a channel path for external air to enter the liquid storage chamber 101.

在另一些可选的实施例中，换气通道为界定或形成于导气部41的外表面和密封支架20之间的凹槽。凹槽远离储液腔101的一端作为换气通道的进气端口延伸至密封支架20的下端26并通过环形槽25与环形壁43之间的间隙和进气口45保持连通。根据具体的使用场景，凹槽可以开设在导气部41的外表面；或开设在孔22的与导气部41接触的内表面；或同时开设于所述导气部41的外表面和孔22的内表面，本申请在此不做限制。In other optional embodiments, the ventilation channel is a groove defined or formed between the outer surface of the air guide portion 41 and the sealing bracket 20. The end of the groove away from the liquid storage chamber 101 serves as the air inlet port of the ventilation channel and extends to the lower end 26 of the sealing bracket 20 and maintains communication with the air inlet 45 through the gap between the annular groove 25 and the annular wall 43. Depending on the specific usage scenario, the groove can be provided on the outer surface of the air guide portion 41; or on the inner surface of the hole 22 that contacts the air guide portion 41; or on both the outer surface of the air guide portion 41 and the inner surface of the hole 22, and this application is not limited thereto.

可选地，换气通道的直径或宽度介于0.2毫米～2.0毫米，其具有合适的宽度或深度尺寸从而形成毛细效应，导气部41或基座40采用例如塑胶等硬质材料能够保持换气通道的进气截面积大小是基本稳定的。当储液腔101内气压过低时，在内外压力差的驱动下，至少部分从进气口45进入的外部空气可以通过换气通道进入储液腔101内向其补气，从而降低储液腔101内部的负压，避免储液腔101内由于气压过低导致下液不畅。同时，毛细作用使得换气通道内能够保持来自储液腔101的少量液体基质，当储液腔101内由于温度升高等原因导致气压过大时，液体基质可以进入换气通道使储液腔101降压，从而避免储液腔101因内部气压过大发生漏液。Optionally, the diameter or width of the ventilation channel is between 0.2 mm and 2.0 mm, with suitable width or depth dimensions to create a capillary effect. The use of a hard material, such as plastic, for the air guide portion 41 or base 40 can maintain a substantially stable air intake cross-sectional area of the ventilation channel. When the air pressure within the liquid storage chamber 101 is too low, driven by the internal and external pressure differential, at least a portion of the external air entering through the air inlet 45 can enter the liquid storage chamber 101 through the ventilation channel to replenish the air, thereby reducing the negative pressure within the liquid storage chamber 101 and preventing poor liquid flow due to low air pressure within the liquid storage chamber 101. Simultaneously, the capillary effect allows the ventilation channel to retain a small amount of liquid matrix from the liquid storage chamber 101. When the air pressure within the liquid storage chamber 101 is excessive due to factors such as increased temperature, the liquid matrix can enter the ventilation channel to reduce the pressure in the liquid storage chamber 101, thereby preventing leakage from the liquid storage chamber 101 due to excessive internal air pressure.

R2示出了外部空气进入电子雾化装置100后的另一条气流路径，即外部空气通过上述包括第一通道部分、第二通道部分和连接通道部分的换气通道进入储液腔101的路径。可以理解的是，外界空气从进气通道121进入电子雾化装置100并通过电芯51和壳体10之间的缝隙流通至进气口45后，如R1所示，一部分可以进入雾化腔室211并携带雾化腔室211中存储的由雾化组件30加热雾化液体基质后产生气溶胶经中空管102导出供用户吸食；如R2所示，另一部分可以从密封支架20的下端26，即环形槽25与环形壁43之间的间隙，进入换气通道，并通过纵向孔420、横向槽430和第一凹槽410的顺序进入储液腔101补气以实现储液腔101内外气压差的平衡。R2 shows another airflow path after the external air enters the electronic atomization device 100, that is, the path for the external air to enter the liquid storage chamber 101 through the ventilation channel including the first channel portion, the second channel portion and the connecting channel portion. It can be understood that after the external air enters the electronic atomization device 100 from the air inlet channel 121 and flows through the gap between the battery cell 51 and the shell 10 to the air inlet 45, as shown in R1, a part of it can enter the atomization chamber 211 and carry the aerosol generated by the atomization component 30 after heating and atomizing the liquid matrix stored in the atomization chamber 211, and is guided out through the hollow tube 102 for the user to inhale; as shown in R2, another part can enter the ventilation channel from the lower end 26 of the sealing bracket 20, that is, the gap between the annular groove 25 and the annular wall 43, and enter the liquid storage chamber 101 through the longitudinal hole 420, the transverse groove 430 and the first groove 410 in sequence to replenish air to achieve a balance of the air pressure difference inside and outside the liquid storage chamber 101.

在其他实施方式中，电子雾化装置100也可以包括多个换气通道，其中，多个换气通道可以包括上述任意一种或多种的换气通道。举例而言，电子雾化装置100可以同时具有两个换气通道，其中一个换气通道包括开设在导气部41的外表面的第一凹槽410和形成于密封支架20上的纵向孔420和横向槽430，另一个换气通道包括形成于孔22的与导气部41接触的表面的第一凹槽410和形成于密封支架20上的纵向孔420和横向槽430。本申请对此不做限制，可以根据实际需要进行设计。能够理解的是，设置多个换气通道可以提升电子雾化装置100的换气效率，缓解由于储液腔101内外气压不平衡而导致下液不畅的问题。In other embodiments, the electronic atomization device 100 may also include a plurality of ventilation channels, wherein the plurality of ventilation channels may include any one or more of the above-mentioned ventilation channels. For example, the electronic atomization device 100 may have two ventilation channels at the same time, wherein one ventilation channel includes a first groove 410 provided on the outer surface of the air guide portion 41 and a longitudinal hole 420 and a transverse groove 430 formed on the sealing bracket 20, and the other ventilation channel includes a first groove 410 formed on the surface of the hole 22 in contact with the air guide portion 41 and a longitudinal hole 420 and a transverse groove 430 formed on the sealing bracket 20. This application does not impose any restrictions on this and can be designed according to actual needs. It can be understood that providing multiple ventilation channels can improve the ventilation efficiency of the electronic atomization device 100 and alleviate the problem of poor liquid discharge due to the imbalance of air pressure inside and outside the liquid storage chamber 101.

在一些实施方式中，如图9和图10所示，密封支架20的下端26和基座40的靠近密封支架20的表面上形成有毛细槽。所述毛细槽连通换气通道，用于吸附和保存从换气通道流出的少量液体基质，进而避免液体基质直接通过进气口45向电子雾化装置100外流出。In some embodiments, as shown in Figures 9 and 10, capillary grooves are formed on the lower end 26 of the sealing bracket 20 and on the surface of the base 40 near the sealing bracket 20. The capillary grooves are connected to the ventilation channel and are used to absorb and store a small amount of liquid matrix flowing out of the ventilation channel, thereby preventing the liquid matrix from directly flowing out of the electronic atomization device 100 through the air inlet 45.

区别于现有技术，本申请公开了一种电子雾化装置100。通过限定在电子雾化装置100中采用非直线换气，可以将从储液腔101中流入换气通道的液体基质的至少一部分保持在换气通道中，以减少自换气通道泄露的液体基质。在一些实施例中，本申请所限定的非直线换气具体指，连通储液腔101的第一通道部分和连通外部大气的第二通道部分在电子雾化装置100的纵向方向Y上相对错开布置。进一步地，针对未能保持在换气通道中的液体基质，本申请还设置毛细槽连通换气通道，毛细槽设置在基座40或密封支架20上，用于吸附从换气通道中流出液体基质，从而继续在一定程度上缓解电子雾化装置100漏液的情况。在具体的实施方式中，保持在换气通道和毛细槽中的液体基质在电子雾化装置100状态的改变下，例如电子雾化装置100倒放或储液腔101内温度升高等情况时，受到电子雾化装置100内压力变化的影响，可以重新通过导液通道流回储液腔101内，维持电子雾化装置100的正常运作。Different from the prior art, the present application discloses an electronic atomization device 100. By limiting the use of non-linear ventilation in the electronic atomization device 100, at least a portion of the liquid matrix flowing into the ventilation channel from the liquid storage chamber 101 can be retained in the ventilation channel to reduce the liquid matrix leaking from the ventilation channel. In some embodiments, the non-linear ventilation defined in the present application specifically refers to that the first channel portion connected to the liquid storage chamber 101 and the second channel portion connected to the external atmosphere are relatively staggered in the longitudinal direction Y of the electronic atomization device 100. Furthermore, for the liquid matrix that cannot be retained in the ventilation channel, the present application also provides a capillary groove to connect the ventilation channel, and the capillary groove is provided on the base 40 or the sealing bracket 20, which is used to adsorb the liquid matrix flowing out of the ventilation channel, thereby continuing to alleviate the leakage of the electronic atomization device 100 to a certain extent. In a specific embodiment, the liquid matrix maintained in the ventilation channel and the capillary groove is affected by the pressure change in the electronic atomization device 100 when the state of the electronic atomization device 100 changes, such as when the electronic atomization device 100 is turned upside down or the temperature in the liquid storage chamber 101 increases, and can flow back into the liquid storage chamber 101 through the liquid guide channel to maintain the normal operation of the electronic atomization device 100.
