Description

Technical Field

[0001] This application relates to the field of atomization equipment technology, specifically to an atomizing core and an atomizer. Background Technology

[0002] Electronic atomizing devices (also known as vaporizers, inhalers, electronic atomizers, etc.) are essentially electronic atomizing products used to heat and atomize atomizing media (such as e-liquid) to form an aerosol that can be inhaled by the user.

[0003] In related technologies, the atomizer core of electronic atomizing devices uses porous ceramic as a liquid guide to direct the e-liquid in the reservoir to the heating element. However, this configuration reduces the liquid retention capacity of the atomizer core. Especially when the electronic atomizing device is inverted, when the porous ceramic is saturated with liquid, bubbles will form in the reservoir. When the electronic atomizing device is inverted, the bubbles will rise to the vicinity of the lower oil hole. The air exchange threshold decreases, resulting in a smaller negative pressure of the bubbles. This causes the atomizing medium in the reservoir to permeate into the aerosol channel, and may even cause blockage. Utility Model Content

[0004] In view of this, this application provides an atomizing core that effectively prevents the atomizing medium in the reservoir from permeating into the aerosol channel when the electronic atomizing device is inverted. Furthermore, this application also provides an atomizer including the aforementioned atomizing core.

[0005] To achieve the above objectives, this application provides the following technical solution: An atomizing core, comprising: The exhaust pipe includes a first pipe section and a second pipe section connected to each other; the inner diameter of the first pipe section is larger than the inner diameter of the second pipe section, and the connection position between the first pipe section and the second pipe section has a stepped surface, wherein a liquid guiding channel is formed on the stepped surface to connect the first pipe section and to guide the atomizing medium. An atomizing component is arranged in the first pipe section and covers the liquid guiding channel; the atomizing component has an air guiding channel that is coaxial with the second pipe section and passes through the atomizing component.

[0006] Optionally, the atomizing component includes: A liquid guide is provided to cover the liquid guide channel, and a gas guide channel is provided, wherein the inner diameter of the gas guide channel is less than or equal to the inner diameter of the second pipe section; The heating element is connected to the liquid and arranged on the inner wall of the air guiding channel.

[0007] Optionally, the end face of the liquid-conducting pipe that is away from the second pipe section is the first end face, and the first end face is a conical surface.

[0008] Optionally, the first end face is provided with a first groove, which extends from the inner wall of the air guiding channel toward the outer peripheral surface of the liquid guiding channel.

[0009] Optionally, the atomizing component includes: A liquid guide is provided to cover the liquid guide channel, and a gas guide channel is provided. The heating element is connected to the fluid-conducting liquid; The end face of the liquid-conducting element that is away from the second pipe section is the first end face, and the heating element is arranged on the first end face.

[0010] Optionally, the inner wall of the air guide channel has a dense coating to prevent the atomizing medium from seeping into the air guide channel.

[0011] Optionally, the inner wall surface of the second pipe section and / or the inner wall surface of the air guide channel are provided with a second groove, and the extension direction of the second groove is parallel to the axial direction of the second pipe section.

[0012] Optionally, the second pipe segment has a protrusion at one end near the first pipe segment, the protrusion being arranged around the air inlet of the second pipe segment and extending into the cavity of the first pipe segment. The fluid-conducting portion is at least partially fitted onto the protrusion.

[0013] An atomizer, comprising: The shell has an internal liquid storage chamber; The atomizing core is any one of the atomizing cores described above. The atomizing core is arranged inside the housing, and the second tube section of the atomizing core penetrates the liquid storage cavity. The stepped surface of the atomizing core is flush with or lower than the bottom wall of the liquid storage cavity.

[0014] Optionally, the housing includes a body and an oil filler cap, the oil filler cap being detachably connected to the body and used to form the top wall of the reservoir. The second pipe section has a pressure relief hole on the side away from the first pipe section; and / or, the end of the second pipe section away from the first pipe section has a notch extending toward the first pipe section.

[0015] This application provides an atomizing core including an exhaust pipe and an atomizing component. The exhaust pipe is a variable-diameter pipe with a stepped surface and includes a first pipe section and a second pipe section. The liquid guiding channel of the atomizing core is opened on the stepped surface of the exhaust pipe, and the atomizing component is arranged in the first pipe section with a larger inner diameter. In this arrangement, the liquid guiding channel and the atomizing component are arranged vertically, so that the end face of the liquid inlet of the liquid guiding channel is flush with or lower than the bottom wall of the liquid storage chamber. That is, the stepped surface is flush with or lower than the bottom wall of the liquid storage chamber. In this way, when the electronic cigarette equipped with the atomizing core of this embodiment is inverted, the atomizing medium in the liquid storage chamber will be separated from the liquid guiding channel of the atomizing core, so that the atomizing medium in the liquid storage chamber cannot enter the atomizing component through the liquid guiding channel. Thus, it can effectively prevent the atomizing medium from permeating into the aerosol channel through the liquid guiding channel and the atomizing component when the electronic cigarette is inverted, thereby avoiding blockage caused by this.

[0016] Furthermore, continuing as described above, in this embodiment, the atomizing component is located inside the first tube segment and has an air guide channel coaxial with the second tube segment and penetrating the atomizing component. Under this arrangement, when the electronic cigarette equipped with the atomizing core of this embodiment is in use, the aerosol is formed inside the air guide channel and / or at the end of the air guide channel. In this way, the path for the aerosol to enter the inner cavity of the second tube segment after formation is relatively simple. Compared with the technical solution where the output path of the aerosol is tortuous, the atomizing core in this embodiment is more likely to carry the aerosol out during use and can reduce contact with the cold wall surface (the cold wall surface refers to the wall surface used to form the output path and which has a low temperature), thereby helping to reduce the generation of condensate.

Detailed Implementation

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Electronic cigarettes (also known as vaporizers, inhalers, electronic atomizers, etc.) are a substitute for traditional tobacco products. They are essentially electronic atomization products used to heat and atomize an atomizing medium (such as e-liquid) to form an aerosol that can be inhaled by the user.

[0037] In related technologies, electronic cigarettes include a power supply unit and an atomizer.

[0038] The power supply unit is electrically connected to the atomizer and is used to provide power to the atomizer.

[0039] The atomizer includes a housing and an atomizing core. The housing contains a reservoir for storing the atomizing medium, and the atomizing core is disposed within the housing and communicates with the reservoir via a liquid guiding channel. More specifically, the atomizing core includes a liquid guide and a heating element. The liquid guide communicates with the reservoir via the liquid guiding channel and directs the atomizing medium from the channel to the heating element, allowing the medium to atomize into an aerosol under the heating of the heating element.

[0040] Furthermore, in related technologies, the atomizer core of an electronic cigarette uses porous ceramic as a liquid guide to direct the e-liquid in the reservoir to the heating element. However, this design reduces the liquid retention capacity of the atomizer core, especially when the electronic cigarette is inverted. When the porous ceramic is saturated with liquid, bubbles will form in the reservoir. When the electronic cigarette is inverted, the bubbles will rise to the vicinity of the lower oil hole. The air exchange threshold decreases, resulting in a smaller negative pressure from the bubbles. In addition, about half of the liquid guide is below the liquid surface, and the liquid retention capacity of the porous ceramic material is insufficient. This leads to the atomizing medium in the reservoir penetrating into the aerosol channel, and even causing leakage and blockage of the hole.

[0041] Based on the above issues, such as Figures 1-16 As shown in the figure, this application provides an atomizing core.

[0042] The atomizer core includes an exhaust pipe 1 and an atomizing assembly.

[0043] The exhaust pipe 1 is used to form an aerosol channel, which is specifically a channel for guiding the aerosol out of the air.

[0044] Furthermore, such as Figures 1-16As shown, the exhaust pipe 1 in this embodiment includes a first pipe section 101 and a second pipe section 102; the inner diameter of the first pipe section 101 is larger than the inner diameter of the second pipe section 102, and the connection position of the first pipe section 101 and the second pipe section 102 has a stepped surface; that is, the axial cross section of the exhaust pipe 1 in this application is stepped, and the interior of the exhaust pipe 1 has a stepped hole.

[0045] Furthermore, such as Figure 1 As shown, a liquid guiding channel 103 for guiding the atomizing medium is provided on the stepped surface. The liquid guiding channel 103 is connected to the first pipe section 101 and is used to guide the atomizing medium. That is, the liquid guiding channel 103 penetrates the pipe wall of the exhaust pipe 1 and is connected to the inner cavity of the first pipe section 101, so that the atomizing medium can enter the inner cavity of the first pipe section 101 through the liquid guiding channel 103.

[0046] For example, in some implementations, such as Figure 1 As shown, multiple liquid guiding channels 103 are provided, and the multiple liquid guiding channels 103 are arranged around the outer peripheral surface of the second pipe section 102.

[0047] The number, shape, and size of the liquid guiding channels 103 can be adaptively designed according to the viscosity of the atomizing medium, etc., and this application does not impose specific limitations on them; in the exemplary embodiment, the following continues... Figure 1 As shown, the number of liquid guiding channels 103 can be four. All four liquid guiding channels 103 are arc-shaped holes, and the four liquid guiding channels 103 are evenly arranged around the outer circumference of the second pipe section 102.

[0048] The atomizing component is used to atomize the atomizing medium into an aerosol. In this embodiment, such as... Figure 2 As shown, the atomizing component is arranged in the first pipe section 101 and covers the liquid guiding channel 103. Furthermore, the atomizing component has an air guiding channel that is coaxial with the second pipe section 102 and passes through the atomizing component.

[0049] As described above, in this embodiment, the exhaust pipe 1 is a variable diameter pipe with a stepped surface, and includes a first pipe section 101 and a second pipe section 102; furthermore, the liquid guiding channel 103 of the atomizing core is opened on the stepped surface of the exhaust pipe 1, and the atomizing component is arranged in the first pipe section 101 with a larger inner diameter; in this arrangement, the liquid guiding channel 103 and the atomizing component are arranged vertically, thereby enabling the end face of the liquid inlet of the liquid guiding channel 103 to be flush with or lower than the bottom wall of the liquid storage chamber 6, that is, the upper... The stepped surface is flush with or lower than the bottom wall of the liquid storage chamber 6; in this way, when the electronic cigarette equipped with the atomizing core in this embodiment is inverted, the atomizing medium in the liquid storage chamber 6 will be separated from the liquid guiding channel 103 of the atomizing core, thereby preventing the atomizing medium in the liquid storage chamber 6 from entering the atomizing component through the liquid guiding channel 103. In this way, it can effectively prevent the atomizing medium from penetrating into the aerosol channel through the liquid guiding channel 103 and the atomizing component when the electronic cigarette is inverted, thereby avoiding the blockage caused by this.

[0050] Furthermore, continuing as described above, in this embodiment, the atomizing component is located inside the first tube segment 101 and has an air guide channel coaxial with the second tube segment 102 and penetrating the atomizing component. Under this arrangement, when the electronic cigarette equipped with the atomizing core of this embodiment is in use, the aerosol is formed inside the air guide channel and / or at the end of the air guide channel. In this way, the path for the aerosol to enter the inner cavity of the second tube segment 102 after it is formed is relatively simple. Compared with the technical solution where the output path of the aerosol is tortuous, the atomizing core in this embodiment is more likely to carry the aerosol out during use and can reduce contact with the cold wall surface (the cold wall surface refers to the wall surface used to form the output path and which has a low temperature), thereby helping to reduce the generation of condensate.

[0051] Furthermore, in some preferred embodiments, the liquid guiding channel 103 is located at the center of the stepped surface in the radial direction of the exhaust pipe 1. That is, the liquid guiding channel 103 is neither adjacent to the wall of the first pipe section 101 nor the wall of the second pipe section 102. In this way, air bubbles entering the storage chamber 6 through the atomizing component (specifically, the liquid guiding 2 of the atomizing component) can be prevented from adhering to the wall of the first pipe section 101, ensuring that the atomizing medium in the storage chamber 6 can flow into the atomizing component through the liquid guiding channel 103. Of course, this is not a limitation of this application. In some other embodiments, the liquid guiding channel 103 can be filled with porous ceramic material to ensure that gas can enter the storage chamber 6; or, the shape of the liquid guiding channel 103 can be set to a shape that makes it difficult for air bubbles to be adsorbed, to ensure that gas can enter the storage chamber 6.

[0052] Furthermore, in some preferred embodiments, the exhaust pipe 1 and the atomizing component are integrated as one piece. This simplifies the structure and makes it easier to assemble the atomizing core. In addition, there is no gap between the atomizing component and the exhaust pipe 1, which avoids leakage.

[0053] It should be noted that the statement that the exhaust pipe 1 and the atomizing component are a single unit means that the exhaust pipe 1 and the atomizing component are connected in a non-detachable manner, and there is no gap at the connection point. This does not mean that the exhaust pipe 1 and the atomizing component are made of the same material.

[0054] In an exemplary embodiment, the exhaust pipe 1 is a dense ceramic material component, the atomizing component includes a liquid guide 2 made of porous ceramic material, the exhaust pipe 1 is connected to the liquid guide 2, and the bonding surface between the exhaust pipe 1 and the liquid guide 2 is formed by adhesive bonding.

[0055] In an exemplary embodiment, the exhaust pipe 1 is a dense ceramic material component. During the preparation process of the atomizing core, the exhaust pipe 1 is first prepared by sintering, and then the exhaust pipe 1 is used as a mold to inject (i.e. inject porous ceramic material) and sinter to form the atomizing component.

[0056] In an exemplary embodiment, the exhaust pipe 1 is a dense ceramic material component, and the atomizing component includes a liquid guide 2 made of porous ceramic material. During the preparation process of the atomizing core, the atomizing component and the exhaust pipe 1 are first prepared by sintering process, and then the atomizing component is placed into the exhaust pipe 1 and sintered again to make the atomizing component and the exhaust pipe 1 an integral structure.

[0057] In some embodiments, the atomizing component includes a liquid guide 2 and a heating element 3.

[0058] The liquid guide 2 is used to guide the atomizing medium and direct it to the heating element 3. Specifically, for example... Figure 2 As shown, in this embodiment, the liquid guide 2 is arranged in the first pipe section 101 and covers the liquid guide channel 103 so that the atomizing medium in the liquid storage chamber 6 can flow into the liquid guide 2 through the liquid guide channel 103 and be guided to the heating element 3 under the action of the liquid guide 2.

[0059] Furthermore, in this embodiment, the liquid guide 2 is a porous ceramic material.

[0060] The heating element 3 is used to atomize the atomizing medium to form an aerosol. In some exemplary embodiments, such as Figures 2-4 , Figure 6 as well as Figure 8 As shown, the atomizing core is arranged on the inner wall of the air guide channel.

[0061] In this embodiment, after the heating element 3 of the atomizing component is powered on, its temperature rises rapidly. The atomizing medium in the liquid storage chamber 6 is guided to the area around the heating element 3 under the action of the liquid guide 2, and is instantly atomized to form an aerosol. At the same time, external gas enters the air guide channel and mixes with the aerosol in the air guide channel. After mixing, the mixture enters the user's oral cavity under the action of the second pipe section 102 of the exhaust pipe 1 and other pipe structures.

[0062] Furthermore, in some preferred embodiments, the inner diameter of the gas guide channel is less than or equal to the inner diameter of the second pipe section. This avoids increasing the resistance to aerosol discharge, thus facilitating aerosol discharge and ensuring smooth exhaust. At the same time, this arrangement also helps reduce the contact between aerosol and the pipe wall of the second pipe section 102, thereby helping to avoid the generation of condensate.

[0063] Based on the above-mentioned heating element 3 being located on the inner wall of the air guiding channel, in some embodiments, such as Figures 4-6 As shown, the end face of the liquid guide 2 away from the second pipe section 102 is the first end face 201, and the first end face 201 is a conical surface.

[0064] Understandably, the atomized medium that permeates into the air guiding channel (hereinafter referred to as the leaked liquid for ease of description) will flow along the inner wall of the air guiding channel toward the first end face 201 under the influence of factors such as gravity and surface tension. In this embodiment, the first end face 201 is set as a conical surface. This increases the angle between the first end face 201 and the inner wall of the air guiding channel, which helps to change the direction of the surface tension of the leaked liquid and guide it away from the air guiding channel. This avoids the accumulation of leaked liquid at the air inlet end of the air guiding channel, thereby reducing the probability of the air guiding channel being blocked.

[0065] Furthermore, based on the fact that the first end face 201 is a conical surface, the included angle between the first end face 201 and the inner wall surface of the air guide channel is preferably greater than or equal to 105°. In this way, after the leaking liquid flows to the air inlet end of the air guide channel, it is more easily guided to the first end face 201 and moved away from the air guide channel under the guidance of the first end face 201.

[0066] Furthermore, based on the fact that the first end face 201 is a conical surface, such as Figure 5 and Figure 6 As shown, in some embodiments, the first end face 201 is provided with a first groove 2011, and the first groove 2011 extends from the inner wall surface of the gas guiding channel toward the outer peripheral surface of the guiding liquid 2.

[0067] The first groove 2011 can serve as a guide channel for leakage and a reservoir for liquid. Thus, the leakage liquid overflowing to the air inlet end of the air guide channel flows away from the air guide channel under the action of the first groove 2011. In this configuration, the first groove 2011 can increase the contact area between the leakage liquid and the guide liquid 2, thereby increasing the surface tension of the liquid. At the same time, the first groove 2011 can also divide the leakage liquid, preventing a large amount of leakage liquid from forming a large area, which helps to reduce the probability of the leakage liquid falling directly under the action of gravity.

[0068] It should be noted that the first groove 2011 can be a U-shaped groove or a V-shaped groove, and this application does not make a specific limitation in this regard. In addition, the number of first grooves 2011 can be adapted to the needs. Preferably, multiple first grooves 2011 are provided to ensure that the leakage liquid overflowing to the first end face 201 can flow into the first grooves 2011.

[0069] As mentioned earlier, based on the atomizing component including the liquid guide 2 and the heating element 3, the heating element 3 can be disposed not only on the inner wall surface of the air guide channel but also on the first end face 201. Alternatively, the heating element 3 can be disposed on both the first end face 201 and the inner wall surface of the air guide channel. The following description further illustrates the atomizing core in this application using the example of the heating element 3 being disposed on the first end face 201.

[0070] like Figures 9-13 As shown, the end face of the liquid guide 2 away from the second pipe section 102 is the first end face 201. And the heating element 3 is disposed on the first end face 201.

[0071] Furthermore, the heating element 3 is located on the first end face 201. The heating element 3 can adopt a single-rail or double-rail annular or near-annular design, and the electrode contact adopts a lead wire or pin design. To further match the atomization object, a uniform temperature design is required. The width of the inner ring of the double rail is preferably less than or equal to 7 μm, and the width of the outer ring of the double rail is preferably greater than 7 μm. To further match the atomization object, a non-uniform temperature design is required to facilitate the atomization of atomizing media with different temperature requirements. A dual-temperature zone design is preferred to realize a single-double rail mixing scheme or a two-single rail mixing scheme. The low temperature zone is preferably ≤200℃, and the high temperature zone is >200℃.

[0072] Furthermore, based on the first end face 201, in some embodiments, such as... Figure 12 As shown, the inner wall of the air guide channel has a dense coating 4 to prevent the atomizing medium from seeping into the air guide channel. In this way, the dense coating 4 can prevent the atomizing medium from seeping into the air guide channel, thereby helping to avoid blockage of the air guide channel.

[0073] Furthermore, the aforementioned dense coating 4 is a high thermal conductivity coating. In this way, when the flue gas formed by the mixture of external gas and aerosol flows through the gas guiding channel, the temperature of the flue gas can be transferred to the guiding liquid 2 through the dense coating 4. On the one hand, this helps to reduce the temperature of the flue gas. On the other hand, by heating the guiding liquid 2, it helps to improve the flowability of the atomizing medium in the guiding liquid 2.

[0074] As mentioned earlier, e-cigarettes can be placed upside down. When an e-cigarette is placed upside down, the leaked liquid will flow towards the second tube segment 102 under the influence of gravity and surface tension. That is, when the e-cigarette is placed upside down, the leaked liquid will overflow onto the inner wall of the second tube segment 102. Based on this, in some embodiments, the inner wall of the second tube segment 102 and / or the inner wall of the air guide channel are provided with a second groove 11, and the extension direction of the second groove 11 is parallel to the axial direction of the second tube segment 102.

[0075] The second groove 11 can serve as a guide channel for leakage and an oil reservoir. The leakage that overflows into the second pipe section 102 can be quickly discharged under the action of the second groove 11, while the leakage that remains in the second pipe section 102 will be stored in the second groove 11. In this way, the leakage can be prevented from accumulating too much and forming a blockage, which helps to prevent the aerosol channel from being blocked.

[0076] In an exemplary implementation, such as Figure 7 and Figure 8 As shown, the heating element 3 is located on the inner wall of the air guide channel, and the inner wall of the second pipe section 102 is provided with a second groove 11, and the extension direction of the second groove 11 is parallel to the axial direction of the second pipe section 102.

[0077] In an exemplary implementation, such as Figure 11 As shown, the heating element 3 is located on the first end face 201, and the inner wall of the air guide channel is provided with a second groove 11. The extension direction of the second groove 11 is parallel to the axial direction of the air guide channel.

[0078] Furthermore, it should be noted that the number of second grooves 11 can be adapted to meet specific needs; preferably, multiple second grooves 11 are provided. Moreover, when multiple second grooves 11 are provided, the outline shape of the inner hole in the radial cross-section of the second pipe section 102 can be serrated, staggered, or wavy, etc.

[0079] It should also be noted that in this application Figures 2-4 , Figure 6 , Figure 8 as well as Figures 10-13 The images shown depict the atomizer coil when the e-cigarette is placed upright. When the e-cigarette is placed upside down, the atomizer coil is the coil shown in the attached diagram after being rotated 180° clockwise.

[0080] In some embodiments, the second pipe segment 102 has a protrusion 1021 at one end near the first pipe segment 101. This protrusion 1021 surrounds the air inlet of the second pipe segment 102 and extends into the cavity of the first pipe segment 101. The liquid guide 2 is at least partially fitted onto the protrusion 1021; that is, in this embodiment, part or all of the liquid guide 2 is located between the pipe wall of the second pipe segment 102 and the protrusion 1021. This arrangement extends the shortest path of the atomizing medium from the liquid guide channel 103 to the inner wall of the air guide channel, thereby reducing the risk of leakage and blockage.

[0081] For example, in some implementations, such as Figure 3 As shown, the heating element 3 is located on the inner wall of the air guide channel, and the protrusion 1021 extends into the air guide channel and extends to the position where the heating element 3 is located in the air guide channel.

[0082] Exemplary examples, in other implementations, such as Figure 13 As shown, the heating element 3 is located on the first end face 201; the protrusion 1021 extends to the end of the air inlet of the air guide channel. With this configuration, leakage of the atomizing medium into the air guide channel can be effectively prevented.

[0083] Furthermore, embodiments of this application also disclose an atomizer, such as... Figure 16 As shown, the atomizer in this embodiment includes a housing 5 and an atomizing core. A liquid storage chamber 6 is formed inside the housing 5. The atomizing core is disposed inside the housing 5 and extends through the liquid storage chamber 6. Furthermore, the stepped surface of the atomizing core is flush with or lower than the bottom wall of the liquid storage chamber 6. It should be noted that the atomizing core in this embodiment is the same as that in any of the above embodiments. Therefore, the beneficial effects of the atomizer brought by the atomizing core are detailed above and will not be repeated here.

[0084] Furthermore, in some embodiments, the housing 5 includes a body 501 and an oil filler cap 502, the oil filler cap 502 being detachably connected to the body 501 and used to form the top wall of the liquid storage chamber 6.

[0085] Based on the above structure, during atomizer assembly, the atomizing core is first assembled onto the body 501 to form the first assembly; then, the filling plug cap 502 is assembled onto the first assembly. It should be noted that, to ensure the airtightness of the liquid reservoir 6, the filling plug cap 502 needs to be sealed to both the inner wall of the body 501 and the outer wall of the exhaust pipe 1. However, this means that during assembly, as the filling plug cap 502 moves towards the bottom wall of the liquid reservoir 6, the pressure inside the liquid reservoir 6 will gradually increase, thereby forcing the atomizing medium within the liquid reservoir 6 to seep through the atomizing core into the aerosol channel.

[0086] Based on the above issues, such as Figure 14 and Figure 15As shown, in this embodiment, a pressure relief hole 1022 is further provided on the side of the second pipe section 102 away from the first pipe section 101; and / or, a notch 1023 extending toward the first pipe section 101 is provided at the end of the second pipe section 102 away from the first pipe section 101. In this way, during the assembly process, the oil filler cap 502 can be depressurized through the aforementioned pressure relief hole 1022 and / or notch 1023, thereby preventing excessive pressure inside the liquid storage chamber 6.

[0087] Furthermore, when a pressure relief hole 1022 is provided on the second pipe section 102, the number and size of the pressure relief hole 1022 can be adaptively designed as needed, and this application does not impose specific limitations on this. In a preferred embodiment, the number of pressure relief holes 1022 is greater than or equal to 1, and the hole diameter is greater than or equal to 0.5 mm.

[0088] Furthermore, when a notch 1023 is provided on the second pipe section 102, the size and number of notches 1023 can be adaptively designed as needed, and this application does not impose specific limitations on this. In a preferred embodiment, the width of the notch 1023 is greater than or equal to 0.5 mm.

[0089] Furthermore, in some embodiments, a first liquid collecting chamber 7 is provided below the liquid storage chamber 6, and a second liquid collecting chamber 8 is provided above the liquid storage chamber 6. The bottom wall of the first liquid collecting chamber 7 is provided with an air inlet channel 9, and the top wall of the second liquid collecting chamber 8 is provided with an air outlet channel 10. The air inlet channel 9 is used to introduce external gas into the first liquid collecting chamber 7, and through the first liquid collecting chamber 7, into the air guide channel of the atomizing core. The air outlet channel 10 is used to exhaust the smoke (this smoke refers to the gas formed by the mixture of external gas and aerosol, or the gas discharged into the second liquid collecting chamber 8 through the exhaust pipe 1). With this configuration, both the first liquid collecting chamber 7 and the second liquid collecting chamber 8 can be used to collect leaked liquid, preventing leakage to the outside of the atomizer, thereby improving the user experience of the atomizer.

[0090] Furthermore, to make the suction smoother, in some embodiments, the air intake channel 9 is arranged opposite to the air guide channel, and the air outlet channel 10 is arranged opposite to the exhaust pipe 1. That is, in this embodiment, the axis of the air intake channel 9, the axis of the exhaust pipe 1, and the axis of the air outlet channel 10 coincide, so as to reduce the suction resistance.
