Description

Technical Field

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

[0002] Currently, in ceramic electronic atomizer products on the market, the ceramic core in the electronic atomizer device is mostly conductive by electrodes pressing against each other to achieve a conductive connection. Among them, the electrodes in the electronic atomizer device are all arranged in a coaxial and equal-diameter contact configuration, which can achieve normal use.

[0003] However, if the contact surface of the electrode for contacting the ceramic core is too large, the electrode needs to have sufficient thickness, which will cause the circumferential surface of the electrode to become larger, thereby causing serious heat loss from the atomizing surface of the ceramic core to the electrode, affecting the atomization taste.

[0004] Furthermore, if the contact surface between the electrode and the ceramic core is too small, poor contact can occur, affecting the stability of the electronic atomization device. Furthermore, a small contact surface on the electrode can also create pressure on the atomization surface of the ceramic core, making it prone to cracks and damage, thus shortening the service life of the ceramic core. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide an electrode, an atomizer and an electronic atomization device to solve the technical problem that the conductive and heat conductive structure of the electrode in the electronic atomization device of the prior art in contact with the ceramic core cannot meet the usage requirements.

[0006] To achieve the above objectives, the technical solution adopted in this application is:

[0007] In the first aspect, an embodiment of the present application provides an electrode, comprising a contact section, a reducing section, an insulation section and an extension section connected in sequence, wherein the extension section is used to electrically connect to a circuit board of an electronic atomization device; the inner diameter of the contact section is larger than that of the insulation section, and the contact section has a contact surface for contacting a ceramic core; the inner diameter of the reducing section gradually decreases from the contact section to the insulation section.

[0008] In this way, the inner diameter of the contact section on the electrode is larger than that of the insulation section, and the contact head on the electrode used to contact the ceramic core is enlarged to ensure the contact stability between the electrode and the ceramic core; at the same time, the inner diameter of the insulation section close to the contact section on the electrode is smaller than that of the contact section, thereby reducing the circumferential surface area of ​​the insulation section, which means that the heat loss transferred from the atomization surface on the ceramic core is reduced, which is conducive to improving the atomization taste.

[0009] In one embodiment, the contact segment has a contact surface at its end, and the contact surface is flat so as to make smooth contact with the surface of the ceramic core, thereby ensuring the stability of the electrical contact.

[0010] In one embodiment, the inner diameter of the insulation section is smaller than that of the extension section. The insulation section is formed to have the smallest inner diameter on the electrode. Furthermore, the insulation section is closer to the contact section than the extension section, thereby reducing the circumferential heat conduction area of ​​the insulation section. This helps reduce the heat dissipation from the ceramic core to the electrode.

[0011] The structure on the electrode is improved, and a convex ring extending toward the periphery is provided between the heat-insulating section and the extending section. The convex ring is used to be placed on a fixed carrier to play a role in installing and positioning the electrode.

[0012] In one embodiment, the end face of the convex ring used to contact the fixed carrier and the contact surface on the end of the contact segment are parallel to each other, so that the electrode can be perpendicular to the ceramic core, effectively ensuring that the contact surface on the electrode is in flat contact with the ceramic core, thereby improving the stability of the electrical contact.

[0013] In the second aspect, the embodiment of the present application also provides an atomizer, including a liquid storage tank, a ceramic core, an upper bracket, a lower bracket and the electrode, wherein an atomization chamber is provided between the upper bracket and the lower bracket, and the ceramic core is fixed on the upper bracket; the liquid storage tank is connected to the upper bracket and is connected to the ceramic core through the internal structure of the upper bracket; the electrode is arranged on the lower bracket, and the contact section, the diameter-reducing section and the heat-insulating section on the electrode are all located in the atomization chamber, and the contact surface on the contact section abuts against the ceramic core. In this way, the ceramic core is fixed on the upper bracket and the electrode is fixed on the lower bracket, which is conducive to locking the matching position of the two, so that the ceramic core is in close contact with the contact surface on the electrode, effectively ensuring the stability of the electrical connection.

[0014] The structure of the ceramic core is improved. The ceramic core is provided with a heating plate. The heating plate has a connection portion for contacting the electrode. The contact surface of the electrode abuts against the connection portion of the heating plate. The area of ​​the connection portion of the heating plate is not less than the area of ​​the contact surface. On the one hand, the contact surface of the electrode is located within the range of the connection portion of the heating plate, effectively ensuring the stability of the electrical connection. On the other hand, the connection portion of the heating plate is used to cover the uneven parts on the surface of the ceramic core, so that the contact surface of the electrode can be in smooth contact with the connection portion of the heating plate, thereby improving the contact stability between the two.

[0015] The structure of the lower bracket has been improved. It also features a socket for securing the electrode. A fixing section is located between the insulation section and the extension section of the electrode. This section is designed to create an interference fit with the inner wall of the socket to improve the coaxiality between the electrode and the socket. The contact section of the electrode, which makes contact with the ceramic core, is perpendicular to the core, effectively ensuring smooth contact between the electrode and the ceramic core, thereby improving the contact stability between the electrode and the ceramic core.

[0016] In one embodiment, the inner diameter of the fixed section is larger than that of the extended section. A guide section is provided between the fixed and extended sections, and the inner diameter of the guide section gradually decreases from the fixed section toward the extended section. The opening of the socket on the lower bracket is a flared opening that matches the shape of the guide section. This allows the electrode to automatically align with the flared opening of the socket and smoothly insert into the socket and extend downward, allowing the fixed section of the electrode to be properly installed, preventing the electrode from getting stuck when inserted into the socket, and effectively improving electrode installation efficiency.

[0017] In a third aspect, embodiments of the present application further provide an electronic atomization device, comprising a power supply assembly and the atomizer, wherein the power supply assembly includes a circuit board and a battery for providing power to the atomizer; the circuit board is disposed on the lower bracket, and a sealing seat is disposed between the circuit board and the lower bracket. The extension of the electrode passes through the sealing seat and is electrically connected to the circuit board. Thus, the sealing seat is disposed between the lower bracket and the circuit board, thereby filling the space between the lower bracket and the circuit board and effectively improving the sealing performance.

[0018] The beneficial effects of the electrode, atomizer and electronic atomization device provided by the present application are: compared with the prior art, the present application improves the conductive and heat-conductive structure of the contact between the electrode and the ceramic core. On the one hand, the contact head of the electrode is made larger, that is, the inner diameter of the contact section on the electrode is larger than the insulation section, thereby increasing the contact surface area of ​​the electrode for contact with the ceramic core, avoiding the ceramic core from being easily crushed, and effectively protecting the ceramic core; and, it has better contact conductivity, thereby extending the service life of the ceramic core.

[0019] On the other hand, the area behind the contact head on the electrode is made smaller, that is, the inner diameter of the heat-insulating section on the electrode is smaller than that of the contact section, and the two are transitioned through a variable diameter section, which is beneficial to reducing the surface area of ​​the heat-conducting part of the electrode, thereby reducing the heat loss generated by the atomizing surface of the ceramic core during operation, and effectively improving the atomization taste.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0043] The electrodes in traditional electronic atomization devices all adopt a coaxial equal-diameter contact setting, which can achieve normal use, but the size setting of the contact surface on the electrode for contacting the ceramic core is particularly important. In the related art, in order to increase the contact surface, the electrode is made thicker so that the contact surface on the electrode for contacting the atomization surface of the ceramic core is increased. However, increasing the thickness of the electrode will increase the circumferential surface area of ​​the electrode, which will cause the heat of the atomization surface of the ceramic core to cool down easily, affecting the atomization taste. Specifically, when the ceramic core is atomizing, the heat will be transferred to the electrode during the process of conductive heating of the heating network on the ceramic core, and the electrode will dissipate the heat transferred from the heating network. As mentioned above, after the thickness of the electrode is increased, the circumferential surface of the electrode will become larger, which will cause the heat to be lost faster. Ultimately, the heat is reduced, resulting in a worse taste and affecting use.

[0044] Furthermore, if the contact surface between the electrode and the ceramic core is too small, poor contact will result, affecting the normal operation of the electronic atomization device. Furthermore, if the contact surface between the electrode and the ceramic core is too small, the atomizing surface of the ceramic core will be pressed against the contact surface of the electrode, making the ceramic core easily crushed by the electrode, thus shortening the service life of the ceramic core.

[0045] Here, the embodiments of the present application provide a new type of electrode, atomizer and electronic atomization device, which improves the conductive and heat-conductive structure of the electrode in contact with the ceramic core, has better contact conductivity, increases the contact area, and makes the ceramic core less likely to be broken; at the same time, the surface area of ​​the heat-conducting part of the electrode is reduced, so that the heat loss generated by the atomizing surface on the ceramic core during operation is reduced, which is beneficial to improving the atomization taste, and effectively solves the technical problem that the conductive and heat-conductive structure of the electrode in contact with the ceramic core set in the traditional electronic atomization device cannot meet the usage requirements. It is now described in detail.

[0046] See also Figure 1 In an atomizer, at least a ceramic core 1 and an electrode 2 of the present application are included. The electrode 2 of the present application includes a contact section 21, a diameter-reducing section 22, a heat-insulating section 23 and an extension section 24 connected in sequence, wherein the contact section 21, the diameter-reducing section 22 and the heat-insulating section 23 are close to one end of the electrode 2; the extension section 24 extends toward the other end of the electrode 2, and the extension section 24 is used to electrically connect to the circuit board on the electronic atomization device.

[0047] Please also refer to Figure 1 and Figure 2The contact segment 21 of the electrode 2 has a contact surface 211 for contacting the ceramic core 1. The contact surface 211 is preferably provided at the end of the contact segment 21 so that the contact surface 211 is sufficiently large to contact the ceramic core 1. This ensures stable contact between the contact surface 211 on the electrode 2 and the ceramic core 1, effectively ensuring the operational stability of the electronic atomization device. Furthermore, this prevents the contact surface 211 on the electrode 2 from being too small, which could cause the electrode 2 to easily break the ceramic core 1, thereby extending the service life of the ceramic core 1.

[0048] The inner diameter of the contact section 21 is larger than that of the heat preservation section 23, and the inner diameter of the diameter-reducing section 22 gradually decreases from the contact section 21 to the heat preservation section 23. Figure 2 As shown, the heat preservation section 23 is smaller than the contact section 21, so that the circumferential surface area of ​​the heat preservation section 23 becomes smaller, which means that the heat loss transferred from the atomization surface on the ceramic core 1 is reduced, which is conducive to improving the atomization taste.

[0049] Compared with the prior art, the electrode 2 provided in the embodiment of the present application improves the conductive and heat-conductive structure of the contact between the electrode 2 and the ceramic core 1. On the one hand, the contact head of the electrode 2 is enlarged, that is, the inner diameter of the contact section 21 on the electrode 2 is larger than the insulation section 23, thereby increasing the area of ​​the contact surface 211 on the electrode 2 for contacting the ceramic core 1, preventing the ceramic core 1 from being easily crushed, and effectively protecting the ceramic core 1; and, ensuring the contact stability between the electrode 2 and the ceramic core 1, having better contact conductivity, thereby extending the service life of the ceramic core 1.

[0050] On the other hand, the portion of the electrode 2 beyond the contact head is made smaller, meaning the inner diameter of the insulation section 23 is smaller than that of the contact section 21. A transition occurs between the insulation section and the contact section 21 via the reducing section 22, whose inner diameter gradually decreases from the contact section 21 toward the insulation section 23. The reduced heat conduction area of ​​the insulation section 23 helps reduce the surface area of ​​the electrode capable of conducting heat, thereby reducing heat dissipation from the atomizing surface of the ceramic core 1 during operation and effectively improving the atomized flavor.

[0051] For the structure on the electrode 2, in one embodiment of the present application, please refer to Figure 2 and Figure 3 The contact segment 21 may preferably have a contact surface 211 at the end thereof, and the contact surface 211 is preferably flat so as to make smooth contact with the surface of the ceramic core 1 , thereby ensuring the stability of the electrical contact.

[0052] like Figure 3As shown, the ceramic core 1 is also provided with a heating plate, which has a connecting portion 11 for contacting the electrode 2. The contact surface 211 on the electrode 2 abuts against the connecting portion 11 of the heating plate. In this embodiment, the heating plate can preferably be integrally provided on the ceramic core 1 during its manufacture. The contact surface 211 on the electrode 2 is in smooth contact with the connecting portion 11 of the heating plate to ensure stable electrical contact.

[0053] The area of ​​the heating element's connection portion 11 is not less than the area of ​​the contact surface 211 on the electrode 2. This ensures that the contact surface 211 of the electrode 2 is within the area of ​​the heating element's connection portion 11, effectively ensuring the stability of the electrical connection. Furthermore, the heating element's connection portion 11 covers any uneven areas on the surface of the ceramic core 1, allowing the contact surface 211 on the electrode 2 to make smooth contact with the heating element's connection portion 11, thereby improving the stability of the contact between the two.

[0054] For the structure on the electrode 2, please refer to another embodiment of the present application. Figure 1 and Figure 2 , the inner diameter of the heat preservation section 23 is smaller than that of the extension section 24.

[0055] In this way, the heat preservation section 23 is the portion with the smallest inner diameter on the electrode 2. At the same time, the heat preservation section 23 is closer to the contact section 21 than the extension section 24, so that the heat conduction area of ​​the circumferential surface of the heat preservation section 23 becomes smaller, which is beneficial to reduce the heat generated by the ceramic core 1 from being dissipated on the electrode 2, and effectively improve the atomization taste.

[0056] In actual applications, the extension section 24 on the electrode 2 is connected to the circuit board on the electronic atomization device. If there is heat on the extension section 24, it will directly affect the circuit board, causing the circuit board to easily heat up and affect the normal operation of the circuit board.

[0057] Here, the above-mentioned small inner diameter insulation section 23 before the extension section 24 also plays a role in preventing heat from reaching the extension section 24, avoiding the extension section 24 from easily heating up and affecting the circuit board on the electronic atomization device, thereby effectively improving the working stability of the electronic atomization device.

[0058] For the structure on the electrode 2, please refer to another embodiment of the present application. Figure 2 and Figure 4 A convex ring 25 extending toward the periphery is provided between the heat preservation section 23 and the extension section 24 . The convex ring 25 is used to be placed on a fixed carrier to play a role in installing and positioning the electrode 2 .

[0059] Please also refer to Figure 2 、 Figure 3 and Figure 4The atomizer provided in the embodiment of the present application includes a ceramic core 1, an upper bracket 3, a lower bracket 4, a liquid storage tank 5 and the electrode 2 of the present application. There is an atomization chamber between the upper bracket 3 and the lower bracket 4. The upper bracket 3 is provided with a mounting groove 31, and the ceramic core 1 is fixed in the mounting groove 31 of the upper bracket 3.

[0060] The liquid storage tank 5 is connected to the upper bracket 3 and communicates with the ceramic core 1 through the internal structure of the upper bracket 3.

[0061] The electrode 2 is arranged on the lower bracket 4 , and the contact section 21 , the diameter-reducing section 22 and the heat-insulating section 23 on the electrode 2 are all located in the atomizing chamber M. The contact surface 211 on the contact section 21 abuts against the ceramic core 1 .

[0062] like Figure 3 and Figure 5 As shown, the central axis of the lower bracket 4 has an air intake channel 40, and the electrodes 2 of the present application are respectively provided on both sides of the channel opening of the air intake channel 40. The ceramic core 1 has a heating plate corresponding to the position of the electrode 2, and respectively contacts the contact surfaces 211 on the two electrodes 2.

[0063] In this way, the ceramic core 1 is fixed on the upper bracket 3 and the electrode 2 is fixed on the lower bracket 4, which is conducive to locking the matching position of the two, so that the ceramic core 1 and the contact surface 211 on the electrode 2 are in close contact, effectively ensuring the stability of the electrical connection.

[0064] like Figure 5 、 Figure 6 and Figure 7 As shown, the internal structure of the upper bracket 3 includes two groups of channels, one of which directly passes through the upper and lower end surfaces of the upper bracket 3 , and the group of channels is the atomization channel 30 .

[0065] The air inlet passage 40 on the bracket 4 is as follows: Figure 5 As shown, a through groove is provided on the central axis of the lower bracket 4, and a circuitous channel is provided inside the lower bracket 4 to communicate with the through groove and to communicate with the outside of the electronic atomization device.

[0066] The atomizing chamber M is a cavity formed between the upper support 3 and the lower support 4 . The atomizing channel 30 and the air inlet channel 40 are both connected to the atomizing chamber M.

[0067] like Figure 4 、 Figure 5 and Figure 7 As shown, another set of channels on the upper bracket 3 is centrally connected from the upper end surface of the upper bracket 3 to the mounting groove 31 for mounting the ceramic core 1. This set of channels is the liquid guide channel 32. It allows the aerosol matrix stored in the liquid storage tank 5 to flow into the upper bracket 3 and reach the ceramic core 1.

[0068] Among them, Figure 4As shown, liquid absorbing cotton 12 is provided on the ceramic core 1 to improve the liquid absorbing effect.

[0069] For the structure on the lower bracket 4, in one embodiment of the present application, please refer to Figure 5 and Figure 8 The lower bracket 4 is also provided with a socket 41 for fixing the electrode 2. In combination with the structure of the atomizer of the present application, the lower bracket 4 is provided with sockets 41 located on both sides of the air inlet channel 40 of the central axis of the lower bracket 4. The number of electrodes 2 is the same as that of sockets 41, and they are respectively plugged into each socket 41 of the lower bracket 4.

[0070] The outer periphery of the socket 41 of the lower bracket 4 serves as a fixed carrier for placing the protruding ring 25 on the electrode 2. When the electrode 2 is inserted into the socket 41, the protruding ring 25 on the electrode 2 rests on the outer periphery of the socket 41, so that the electrode 2 can be installed in place.

[0071] In this way, the contact section 21, the reducing section 22 and the heat preservation section 23 on the electrode 2 are all located in the atomization chamber M separated by the upper bracket 3 and the lower bracket 4. The extension section 24 of the electrode 2 is located in the lower bracket 4 and extends to the bottom of the lower bracket 4 so as to be electrically connected to the circuit board on the electronic atomization device.

[0072] In one embodiment of this application, please refer to Figure 2 、 Figure 5 and Figure 8 A fixed section 26 is provided between the heat preservation section 23 and the extension section 24 on the electrode 2 , and the fixed section 26 is used for interference fit with the inner wall of the insertion hole 41 .

[0073] In this embodiment, if Figure 2 As shown, the fixed section 26 on the electrode 2 is located below the convex ring 25 and between the convex ring 25 and the extension section 24. When the electrode 2 is plugged into the socket 41 of the lower bracket 4, as shown in FIG. Figure 4 and Figure 7 As shown, the convex ring 25 rests on the outer periphery of the insertion hole 41, and the fixing section 26 on the electrode 2 is located in the insertion hole 41. At this time, the outer periphery of the fixing section 26 and the inner wall of the insertion hole 41 are interference fit.

[0074] In this way, the fixing section 26 on the electrode 2 is interference-fitted with the inner wall of the socket 41 of the lower bracket 4, thereby improving the coaxiality of the electrode 2 and the socket 41. The contact section 21 on the electrode 2 for contacting the ceramic core 1 is perpendicular to the ceramic core 1, effectively ensuring that the contact surface 211 on the electrode 2 is in smooth contact with the ceramic core 1, thereby improving the contact stability between the electrode 2 and the ceramic core 1 and enhancing the fixing effect of the electrode 2.

[0075] Preferably, if Figure 2As shown, the inner diameter of the fixed section 26 on the electrode 2 is larger than that of the extending section 24 so as to better interference fit with the inner wall of the insertion hole 41 .

[0076] However, a transition structure is required between the fixed section 26 and the extending section 24 to prevent the electrode 2 from getting stuck when being inserted into the insertion hole 41 , thereby affecting the installation efficiency of the electrode 2 .

[0077] For this purpose, please refer to Figure 2 、 Figure 8 and Figure 9 The electrode 2 further comprises a guide section 27 between the fixed section 26 and the extension section 24, and the inner diameter of the guide section 27 gradually decreases from the fixed section 26 to the extension section 24. Figure 8 As shown, the opening of the insertion hole 41 on the lower bracket 4 is preferably a flared opening 411 that matches the shape of the above-mentioned guide section 27.

[0078] In this way, the electrode 2 can be automatically aligned using the flared opening 411 on the socket 41, and can be inserted into the socket 41 and extended downward, so that the fixed section 26 on the electrode 2 is installed in place, avoiding the electrode 2 from getting stuck when inserted into the socket 41, and effectively improving the installation efficiency of the electrode 2.

[0079] In the above embodiment, since the opening of the insertion hole 41 on the lower bracket 4 for mounting the electrode 2 is the expanded opening 411 , a gap is easily formed between the expanded opening 411 and the periphery of the electrode 2 inserted into the insertion hole 41 , affecting the sealing performance.

[0080] Here, if Figure 9 As shown, when the convex ring 25 on the electrode 2 is placed on the outer periphery of the insertion hole 41 of the lower bracket 4, it also plays a role in blocking the gap between the expanded opening 411 and the outer periphery of the electrode 2, effectively improving the sealing performance.

[0081] Preferably, in one embodiment of the present application, the end surface of the convex ring 25 of the electrode 2 for contacting the fixed carrier and the contact surface 211 on the end of the contact segment 21 are parallel to each other. Figure 9 As shown, L1 is a parallel line to the contact surface 211 on the end of the electrode 2, and L2 is a parallel line to the end surface of the convex ring 25 that contacts the outer periphery of the insertion hole 41. L1 and L2 are parallel to each other.

[0082] This allows the electrode 2 to be perpendicular to the ceramic core 1, effectively ensuring that the contact surface 211 on the electrode 2 is in smooth contact with the ceramic core 1, thereby improving the stability of the electrical contact. In addition, the electrode 2 is coaxially aligned with the socket 41 on the lower bracket 4, which also improves the coaxiality of the electrode 2 and the socket 41.

[0083] Please also refer to Figure 4 and Figure 10An embodiment of the present application further provides an electronic atomization device, comprising a power supply assembly and the atomizer of the present application, wherein the power supply assembly comprises a circuit board 6 and a battery (not shown) for providing power to the atomizer.

[0084] like Figure 10 As shown, the circuit board 6 is arranged on the lower bracket 4 , and a sealing seat 7 is provided between the circuit board 6 and the lower bracket 4 . The extension section 24 on the electrode 2 passes through the sealing seat 7 and is electrically connected to the circuit board 6 .

[0085] In this embodiment, the sealing seat 7 has a cavity and a conducting structure N that cooperates with the electrode 2 to pass through and connect with the air intake channel 40 on the lower bracket 4. This allows the air intake channel 40 to connect to the outside of the electronic atomization device, and allows the electrode 2 to smoothly pass through the sealing seat 7 and extend to the circuit board 6.

[0086] Thus, sealing seat 7 is disposed between lower bracket 4 and circuit board 6. On the one hand, sealing seat 7 itself fills the space between lower bracket 4 and circuit board 6, effectively improving sealing. On the other hand, the internal structure of sealing seat 7 ensures that both ends of air inlet passage 40 on lower bracket 4 are connected, allowing electrode 2 to pass smoothly through and reach circuit board 6, achieving electrical connection.

[0087] 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.
