Description

Technical Field

[0001] The present application belongs to the technical field of electronic atomization equipment, and in particular relates to a ceramic core, an atomizer and an electronic atomization device. Background Art

[0002] The ceramic electronic atomization device products currently on the market generally have a ceramic core and an electrode. The contact end of the electrode is connected to the heating plate of the ceramic core to make the heating plate heat up when the electronic atomization device is working, thereby heating and atomizing the aerosol matrix absorbed on the ceramic core.

[0003] In actual use, the aerosol matrix absorbed by the ceramic core will permeate the entire ceramic core and reach the bottom of the ceramic core. Because the heating plate at the bottom of the ceramic core is mainly composed of heating wires with a small area, it cannot prevent the aerosol matrix from leaking out from the bottom of the ceramic core and dripping into the air inlet channel below the ceramic core, causing the electronic atomization device to leak, affecting the user's normal use. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a ceramic core, an atomizer and an electronic atomization device to solve the technical problem that the ceramic core structure in the electronic atomization device of the prior art easily causes liquid leakage in the electronic atomization device.

[0005] To achieve the above objectives, the technical solution adopted in this application is:

[0006] In a first aspect, an embodiment of the present application provides a ceramic core for use in an atomizer, the ceramic core comprising:

[0007] Ceramic core body;

[0008] The heating element includes a heating portion and a heat dissipation portion connected to each other. The heating portion is arranged on the side wall surface of the ceramic core body, and the heat dissipation portion extends from the heating portion to the bottom surface of the ceramic core body and covers at least part of the bottom surface of the ceramic core body.

[0009] The heating element on the ceramic core is now located on the side of the core body. The bottom of the core body features a heat sink with a larger heat dissipation surface. This heat sink connects to the heating element and also serves as a connection to the electrodes. The heat sink seals the bottom of the ceramic core, preventing the aerosol matrix from escaping from the bottom of the core body and reducing the risk of leakage.

[0010] In one embodiment, the heating elements are provided on opposite sides of the ceramic core body, and opposite sides of the heat dissipation element are connected to the heating elements on both sides. Thus, the heating elements are provided on both sides of the ceramic core body, uniformly heating and atomizing the aerosol matrix absorbed by the ceramic core body, thereby improving the atomization effect.

[0011] In one embodiment, a heating portion of the heating element is provided on each sidewall of the ceramic core body, and each heating portion on each sidewall is connected to the heat dissipation portion. Thus, the heating portion of the heating element is provided along the entire outer peripheral sidewall of the ceramic core body, thereby uniformly heating the aerosol matrix absorbed by the ceramic core body and effectively improving the atomization effect.

[0012] The structure of the ceramic core body has been improved. Outwardly extending extensions are provided on opposite sides of the ceramic core body. These extensions have inclined surfaces that are inclined toward the bottom of the ceramic core body. The heating element of the heating element is positioned on these inclined surfaces. This utilizes the inclined surfaces of the extensions to increase the area of contact with the gas. The heating element, positioned on these inclined surfaces, atomizes the gas flowing through it, effectively increasing the amount of atomization and enhancing the atomization effect.

[0013] Another improvement to the structure of the ceramic core body is that it also includes an outwardly extending extension portion, which is arranged around the outer periphery of the ceramic core body and has an inclined surface inclined toward the bottom of the ceramic core body. The heating portion of the heating element is arranged on the inclined surface of the extension portion. In this way, a circle of extension portions is added to the entire outer peripheral sidewall of the ceramic core body, and the heating portions of the heating element are distributed on the inclined surface of this circle of extension portions, thereby increasing the area of the entire ceramic core that can contact the gas, maximizing the amount of atomization and improving the atomization effect.

[0014] In the second aspect, an embodiment of the present application also provides an atomizer, comprising a liquid storage tank, an electrode, an upper bracket, a lower bracket and the ceramic core, wherein the upper bracket is provided with a liquid guide channel and a mounting groove for fixing the ceramic core, and the liquid guide channel is connected to the mounting groove; the liquid storage tank is connected to the upper bracket and is connected to the liquid guide channel; the electrode is arranged on the lower bracket, and the contact end of the electrode extends to the ceramic core and is against the heat dissipation part of the heating element to achieve electrical connection with the heating element.

[0015] In one embodiment, liquid-absorbing cotton is further provided on the ceramic core, and the liquid-absorbing cotton is located in the installation groove, thereby improving the liquid-absorbing effect on the ceramic core.

[0016] The upper bracket structure has been improved to include an air outlet and an atomization channel connected to the air outlet. The atomization channels extend to the mounting slots. The ceramic core is mounted in the mounting slots, and the heating element of the heating element is located in the atomization channel. The ceramic core absorbs the aerosol matrix in the mounting slots, and the heating element on the sidewall of the ceramic core is also located in the atomization channel. The heating element atomizes the aerosol matrix absorbed by the ceramic core, and the generated aerosol is output from the atomization channel to the air outlet, improving the output effect.

[0017] The lower bracket structure has been improved to include an air inlet channel positioned below the ceramic core. The channel's opening is located within the projection of the heat dissipation portion of the heating element. This prevents aerosol substrate absorbed by the ceramic core from dripping into the air inlet channel from within the heat dissipation portion, effectively reducing the risk of aerosol substrate dripping into the air inlet channel.

[0018] In one embodiment, a liquid drainage surface inclined outward is provided on the outer periphery of the channel opening of the air inlet channel, so that the aerosol matrix present on the channel opening of the air inlet channel can be discharged along the liquid drainage surface, further reducing the risk of the aerosol matrix falling into the air inlet channel.

[0019] Thirdly, embodiments of the present application further provide an electronic atomization device comprising a power supply assembly and the aforementioned atomizer. The power supply assembly includes a circuit board and a battery that provides power to the atomizer. This provides power to the heating element on the ceramic core, heating and atomizing the aerosol matrix absorbed by the ceramic core, thereby enabling the electronic atomization device to operate normally.

[0020] The beneficial effects of the ceramic core, atomizer and electronic atomization device provided in the present application are: compared with the prior art, the ceramic core structure used in the electronic atomization device is improved, a heating element is provided on the main body of the ceramic core, the heating element includes a heating part and a heat dissipation part, and the heating part is arranged on the side of the ceramic core body, thereby improving the bottom heating on the traditional ceramic core to side heating.

[0021] The heat dissipation portion of the heating element is connected to the heating element and extends to the bottom surface of the ceramic core body, covering at least a portion of the bottom surface of the ceramic core body, thereby forming a cover structure on the bottom surface of the ceramic core. The heat dissipation portion seals the bottom surface of the ceramic core, preventing aerosol matrix absorbed by the ceramic core from escaping from the bottom of the ceramic core, effectively reducing the risk of aerosol matrix dripping into the air inlet channel located below the ceramic core. This solves the problem of ceramic core structures commonly used in traditional electronic atomization devices, which can easily lead to liquid leakage in electronic atomization devices, and improves the user experience.

[0041] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0042] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0043] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this 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 cannot be understood as a limitation on this application.

[0044] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature specified 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.

[0045] In traditional electronic atomization devices, a ceramic core is used to heat and atomize the aerosol matrix. The ceramic core has micropores that allow it to fully absorb the aerosol matrix. The aerosol matrix easily passes through the micropores on the ceramic core, permeating the entire ceramic core and reaching the bottom of the ceramic core. The heating plate on the ceramic core is set at the bottom of the ceramic core to heat the ceramic core and atomize the aerosol matrix. The heating plate is generally composed of a heating wire. Because the area of the heating wire is too small, the heating wire cannot prevent the aerosol matrix from leaking out of the bottom of the ceramic core.

[0046] It can be seen that the aerosol matrix gathered at the bottom of the ceramic core and not atomized in time will leak out from the bottom of the ceramic core and directly drip into the air inlet channel located below the ceramic core, and flow out of the electronic atomization device, causing the electronic atomization device to leak and affect its use.

[0047] Here, the embodiments of the present application provide a new type of ceramic core, atomizer and electronic atomization device, improve the structure of the ceramic core, and change the heating element on the ceramic core to heat the side of the ceramic core. The bottom of the ceramic core has a heat dissipation part with an increased heat dissipation surface. The heat dissipation part is used to seal the bottom of the ceramic core, thereby preventing the aerosol matrix from leaking from the bottom of the ceramic core, reducing the risk of the leaked aerosol matrix dripping into the air inlet channel and flowing out of the outside of the atomizer, and effectively solving the problem that the ceramic core structure commonly used in traditional electronic atomization devices easily causes liquid leakage in the electronic atomization device. It is now described in detail.

[0048] See also Figure 1 The ceramic core provided in the embodiment of the present application includes a ceramic core body 1 and a heating element 2.

[0049] In this embodiment, the ceramic core body 1 may preferably be a rectangular body, and micropores may be opened on the ceramic core according to usage requirements to improve the liquid absorption effect.

[0050] The heating element 2 includes a heating portion 21 and a heat dissipation portion 22 connected to each other. The heating portion 21 and the heat dissipation portion 22 can be integrally formed during the production of the heating element 2 to ensure the connection strength between the heating portion 21 and the heat dissipation portion 22 .

[0051] The heating portion 21 of the heating element 2 is arranged on the side wall surface of the ceramic core body 1. Specifically, it can be understood that Figure 1 As shown, the ceramic core body 1 has at least upper and lower end surfaces, and the side walls other than the upper and lower end surfaces are all the side walls of the ceramic core body 1. The heating portion 21 can preferably be evenly arranged on the side walls of the ceramic core body 1 to ensure uniform heating of the ceramic core body 1, thereby improving the atomization saturation.

[0052] The heat dissipation portion 22 extends from the heating portion 21 to the bottom surface of the ceramic core body 1 and covers at least a portion of the bottom surface of the ceramic core body 1. The heat dissipation portion 22 of the heating element 2 is used to seal the bottom surface of the ceramic core, thereby preventing the aerosol matrix absorbed by the ceramic core body 1 from leaking out from the bottom of the ceramic core body 1.

[0053] The heat dissipation portion 22 can also serve as a connection portion electrically connected to an external electrode. The electrode contact end of the electronic atomization device can abut against the heat dissipation portion 22 to achieve electrical connection with the heating element 2.

[0054] Compared with the prior art, the embodiment of the present application improves the ceramic core structure on the electronic atomization device. A heating body 2 is provided on the main body 1 of the ceramic core. The heating body 2 includes a heating part 21 and a heat dissipation part 22. The heating part 21 is arranged on the side of the ceramic core main body 1, and the bottom heating on the traditional ceramic core is improved to side heating.

[0055] Heat dissipation portion 22 of heating element 2 is connected to heating portion 21 and extends to the bottom surface of ceramic core body 1, covering at least a portion of the bottom surface of ceramic core body 1, thereby forming a cover structure on the bottom surface of the ceramic core. Heat dissipation portion 22 seals the bottom surface of the ceramic core, effectively preventing aerosol matrix absorbed by the ceramic core from escaping from the bottom of the ceramic core.

[0056] In addition, the heat on the heat dissipation part 22 can be used to heat and atomize the aerosol matrix gathered at the bottom of the ceramic core body 1, thereby increasing the atomization saturation of the aerosol matrix on the ceramic core, further eliminating the aerosol matrix gathered at the bottom of the ceramic core body 1, and effectively reducing the risk of the aerosol matrix dripping into the air inlet channel located below the ceramic core, thereby solving the leakage problem of the electronic atomization device and improving the user experience.

[0057] Regarding the structure of the heat dissipation portion 22, in one embodiment of the present application, please refer to Figure 1 The heat dissipation portion 22 of the heating element 2 is a heat dissipation baffle disposed on the bottom surface of the ceramic core body 1. The heat dissipation baffle covers at least a portion of the bottom surface of the ceramic core body 1. Preferably, the heat dissipation baffle can also cover the entire bottom surface of the ceramic core body 1. In this way, the bottom surface of the ceramic core body 1 is sealed, effectively improving the sealing effect.

[0058] Regarding the arrangement of the heating portion 21 of the heating element 2 on the ceramic core body 1, in one embodiment of the present application, please refer to Figure 1 The heating parts 21 of the heating element 2 are respectively provided on two opposite sides of the ceramic core body 1, and the two opposite sides of the heat dissipation part 22 are respectively connected to the heating parts 21 on both sides.

[0059] Thus, the heating parts 21 are provided on both sides of the ceramic core body 1 to evenly heat and atomize the aerosol matrix absorbed on the ceramic core body 1 , thereby improving the atomization effect.

[0060] In this embodiment, if Figure 2 As shown, both sides of the ceramic core body 1 can also cooperate with the structure on the mounting carrier of the ceramic core, and the interior of these mounting carriers can be provided with atomization channels 44 located on both sides of the ceramic core body 1, so that the aerosol produced by heating and atomization on both sides of the ceramic core body 1 is just located in the atomization channel 44 and output along the atomization channel 44.

[0061] In another embodiment of the present application (not shown), a heating portion 21 of the heating element 2 is provided on each side wall of the ceramic core body 1 , and the heating portion 21 on each side wall is respectively connected to the heat dissipation portion 22 .

[0062] In this way, the heating portion 21 of the heating element 2 is provided on the entire peripheral side wall of the ceramic core body 1, so as to uniformly heat the aerosol matrix absorbed on the ceramic core body 1, thereby effectively improving the atomization effect and increasing the atomization amount.

[0063] In practical applications, such as Figure 3 As shown, the gas enters from the air inlet channel 51 located below the ceramic core body 1, first reaches the bottom of the ceramic core body 1, and then rises and is output through the atomization channels 44 on both sides of the ceramic core body 1. Since the ceramic core of this application changes the heating part 21 of the heating element 2 from the bottom of the ceramic core to the side of the ceramic core, if the side of the ceramic core body 1 is a vertical surface, the area on the ceramic core that can contact the gas will become smaller, resulting in a significant reduction in the amount of atomization, affecting the atomization effect.

[0064] Here, in order to solve the above problems, the structure of the ceramic core body 1 is further improved. In one embodiment of the present application, please refer to Figure 2 、 Figure 3 and Figure 4 An outwardly extending extension portion 11 is provided on opposite sides of the ceramic core body 1. The extension portion 11 has an inclined surface 12 inclined toward the bottom of the ceramic core body 1. The heating portion 21 on the heating element 2 is provided on the inclined surface 12 of the extension portion 11.

[0065] In this way, an extension portion 11 is added to the side of the ceramic core body 1, and the inclined surface 12 on the extension portion 11 can be used to increase the area in contact with the gas. The heating portion 21 of the heating element 2 is arranged on the inclined surface 12 of the extension portion 11 to atomize the gas flowing through, effectively increasing the atomization amount and improving the atomization effect.

[0066] It can be seen that the above embodiment is arranged for the carrier in which the atomization channel 44 is located on opposite sides of the ceramic core, but for the carrier structure in which the atomization channel 44 is respectively on the entire outer peripheral side wall of the ceramic core, in another embodiment of the present application (not shown in the figure), the ceramic core body 1 also includes an outwardly extending extension portion 11, and the extension portion 11 is arranged around the outer periphery of the ceramic core body 1. The extension portion 11 has an inclined surface 12 inclined toward the bottom of the ceramic core body 1, and the heating portion 21 on the heating element 2 is evenly arranged on the inclined surface 12 of the above-mentioned fully surrounded extension portion 11.

[0067] In this way, a circle of extension part 11 is added to the entire outer peripheral side wall of the ceramic core body 1, which is equivalent to adding a convex ring on the outer periphery of the ceramic core body 1. This circle of extension part 11 has a circle of inclined surface 12 inclined toward the bottom surface of the ceramic core body 1. The heating part 21 on the heating element 2 can be preferably evenly distributed on the inclined surface 12 of the circle of extension part 11, thereby increasing the area of the entire ceramic core that can contact the gas, maximizing the atomization amount, and improving the atomization effect.

[0068] Regarding the structure of the heating portion 21 on the heating element 2, in one embodiment of the present application, please refer to Figure 5 and Figure 2 The heating portion 21 includes a heating wire 211 and connecting portions 212 connected to both sides of the heating wire 211 .

[0069] The shape of the heating wire 211 can be a mesh shape, a snake shape, a spiral shape, etc., which is not specifically limited here.

[0070] Connecting portions 212 are connected to opposite sides of the heating wire 211. These connecting portions 212 are used to connect to the heat dissipation portion 22, thereby integrally connecting the heating portion 21 and the heat dissipation portion 22. Heat generated by the heating wire 211 is transferred to the heat dissipation portion 22 via the connecting portions 212, where it gradually dissipates. The residual heat from the heat dissipation portion 22 also atomizes the aerosol matrix that accumulates at the bottom of the ceramic core, effectively preventing the aerosol matrix absorbed by the ceramic core from escaping from the bottom of the ceramic core body 1.

[0071] Please also refer to Figure 6 、 Figure 7 and Figure 8 The present invention also provides an atomizer, comprising an electrode 3, an upper bracket 4, a lower bracket 5, a liquid reservoir 7, and the ceramic core 100 of the present invention. The upper bracket 4 is provided with a liquid guide channel 41 and a mounting groove 42 for fixing the ceramic core 100. The liquid guide channel 41 is connected to the mounting groove 42. The liquid reservoir 7 is used to load aerosol substrate. The liquid reservoir 7 is connected to the upper bracket 4 and is connected to the liquid guide channel 41, allowing the aerosol substrate stored in the liquid reservoir 7 to flow along the liquid guide channel 41 to the ceramic core 100.

[0072] The electrode 3 is arranged on the lower bracket 5, and one end of the electrode 3 is used to be electrically connected to the circuit board 8 of the electronic atomization device. The contact end on the other end of the electrode 3 extends to the ceramic core 100 and is against the heat dissipation part 22 of the heating element 2 to achieve electrical connection with the heating element 2.

[0073] Please also refer to Figure 6 and Figure 7 Liquid-absorbing cotton 6 is also provided on the ceramic core 100. Specifically, the liquid-absorbing cotton 6 can be provided on the other end surface of the ceramic core 100 away from the heat dissipation portion 22. The liquid-absorbing cotton 6 is fixed to the ceramic core 100 and located in the mounting groove 42. It can be preferably provided at the connection between the mounting groove 42 and the liquid guide channel 41 to centrally absorb the aerosol matrix flowing from the liquid guide channel 41 into the mounting groove 42, and then penetrate into the ceramic core 100, effectively improving the liquid absorption effect on the ceramic core 100.

[0074] In this embodiment, if Figure 7 As shown, the liquid absorbent cotton 6 can preferably be a ring body, and the shape of the ring body matches the upper end surface of the ceramic core 100. When the liquid absorbent cotton 6 is set on the upper end surface of the ceramic core 100, the center hole of the ring body forms a liquid collecting groove on the upper end surface of the ceramic core 100, further improving the liquid absorption effect.

[0075] For the specific structure of the upper bracket 4, please refer to Figure 2 and Figure 3 The upper bracket 4 is further provided with an air outlet 43 and an atomization channel 44 connected to the air outlet 43. The air outlet 43 is used to communicate with the output channel of the electronic atomization device. The atomization channel 44 extends to the mounting groove 42. The ceramic core 100 is disposed in the mounting groove 42, and the heating portion 21 of the heating element 2 is located in the atomization channel 44.

[0076] In this way, the ceramic core 100 absorbs the aerosol matrix in the installation groove 42, and the heating portion 21 on the side wall of the ceramic core 100 is simultaneously located in the atomization channel 44. The heating portion 21 atomizes the aerosol matrix absorbed on the ceramic core 100, and the generated aerosol can be directly output from the atomization channel 44 to the air outlet 43, thereby improving the output effect.

[0077] For the specific structure of the lower bracket 5, please refer to the embodiment of the present application. Figure 3 and Figure 6 The lower bracket 5 is provided with an air intake channel 51 located below the ceramic core 100 , and the channel opening of the air intake channel 51 is located within the projection range of the heat dissipation portion 22 of the heating element 2 .

[0078] In this embodiment, if Figure 6 and Figure 7As shown, the air inlet channel 51 can be preferably located on the central axis of the lower bracket 5, and the ceramic core 100 is arranged on the mounting groove 42 of the upper bracket 4 and is preferably coaxially aligned with the air inlet channel 51. The electrodes 3 are arranged on the lower bracket 5 and fixed to the slots on both sides of the air inlet channel 51. The upper ends of the electrodes 3 serve as contact ends, abutting against the heat dissipation portion 22 at the bottom of the ceramic core body 1 to achieve electrical connection with the heating element 2.

[0079] The heat dissipation portion 22 of the heating element 2 on the ceramic core 100 covers at least a portion of the bottom surface of the ceramic core body 1. The opening of the air inlet passage 51 on the lower bracket 5 is located within the vertical projection range M of the heat dissipation portion 22 onto the lower bracket 5. Therefore, aerosol substrate absorbed by the ceramic core 100 cannot drip into the air inlet passage 51 from within the blocking range of the heat dissipation portion 22, effectively reducing the risk of aerosol substrate dripping into the air inlet passage 51.

[0080] Preferably, if Figure 3 As shown, a liquid discharge surface 52 tilted outward is provided on the outer periphery of the channel opening of the air inlet channel 51 so that the aerosol matrix present on the channel opening of the air inlet channel 51 can be discharged along the liquid discharge surface 52, further reducing the risk of the aerosol matrix falling into the air inlet channel 51.

[0081] Please also refer to Figure 6 and Figure 8 The present invention also provides an electronic atomization device, comprising a power supply assembly and the atomizer of the present invention. In this embodiment, the atomizer is integrally mounted on the electronic atomization device; in other embodiments, the atomizer can be used as a replacement component and can be detachably mounted on the electronic atomization device.

[0082] The power supply assembly includes a circuit board 8 and a battery (not shown) that provides power to the atomizer. The circuit board 8 is arranged on the lower bracket 5, and can be specifically fixed to the bottom of the lower bracket 5. The electrode 3 passes through the lower bracket 5 and is electrically connected to the circuit board 8.

[0083] In this way, the heating element 2 on the ceramic core 100 is powered, and the aerosol matrix absorbed on the ceramic core 100 is heated and atomized, allowing the electronic atomization device to operate normally.

[0084] Preferably, if Figure 6 and Figure 8 As shown, a sealing seat 9 is further provided between the circuit board 8 and the lower bracket 5 , and the other end of the electrode 3 away from contact with the ceramic core 100 passes through the sealing seat 9 and is electrically connected to the circuit board 8 .

[0085] In this embodiment, if Figure 6As shown, the interior of the sealing seat 9 has a cavity and a conducting structure N that can cooperate with the electrode 3 to pass through and communicate with the air intake channel 51 on the lower bracket 5. This can not only allow the air intake channel 51 to be connected to the outside of the electronic atomization device, but also enable the electrode 3 to smoothly pass through the sealing seat 9 and extend to the circuit board 8 to achieve electrical connection.

[0086] The working principle of the electronic atomization device of this application is:

[0087] like Figure 8 As shown, when the electronic atomization device is working, external air enters the electronic atomization device from the bottom air inlet of the electronic atomization device, reaches the air inlet channel 51 of the lower bracket 5 and flows upward.

[0088] The ceramic core 100 is arranged on the upper bracket 4 and is located directly above the air inlet channel 51. The upper bracket 4 is connected to the liquid storage tank 7 and has two sets of channels, such as Figure 9 and Figure 10 As shown, one group is a liquid guide channel 41 connected to the liquid storage tank 7. The aerosol matrix stored in the liquid storage tank 7 reaches the ceramic core 100 set on the upper bracket 4 through the liquid guide channel 41. The ceramic core 100 is provided with a liquid absorbent cotton 6 to improve the liquid absorption effect. The other group is an atomization channel 44. One end of the atomization channel 44 is connected to the air outlet 43 on the upper part of the upper bracket 4, and the air outlet 43 is connected to the output channel of the electronic atomization device; the other end is connected to the side of the mounting groove 42 for mounting the ceramic core 100. The ceramic core 100 is set in the mounting groove 42 of the upper bracket 4. The top of the ceramic core body 1 is located at the connection between the liquid guide channel 41 and the mounting groove 42, and the bottom and side of the ceramic core body 1 are located in the atomization channel 44.

[0089] Therefore, if Figure 8 As shown (the arrows in the figure are the flow direction of the gas), the gas flows upward and preferentially reaches the bottom of the ceramic core body 1 and is diverted to both sides. It is heated by the heating part 21 of the heating element 2 on the side of the ceramic core body 1 to be atomized, and flows upward along the atomization channel 44, and is finally output from the air outlet 43 along the output channel of the electronic atomization device.

[0090] Although the air inlet channel 51 is located directly below the ceramic core 100, the aerosol matrix absorbed on the ceramic core can easily drip directly into the air inlet channel 51. However, a heat dissipation portion 22 of the heating element 2 is provided on the bottom surface of the ceramic core body 1. The heat dissipation portion 22 at least seals the portion of the bottom surface projection of the ceramic core body 1 covering the air inlet channel 51, thereby preventing the aerosol matrix absorbed on the infiltrated ceramic core 100 from directly dripping into the air inlet channel 51, effectively reducing the risk of leakage in the electronic atomization device.

[0091] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
