Description

Technical Field

[0001] This application belongs to the field of electronic atomization equipment technology, and particularly relates to an electronic atomization device. Background Technology

[0002] With the technological advancements in electronic atomization devices, users' demands for a superior atomization experience are constantly increasing. As a result, electronic atomization devices on the market are gradually moving towards larger capacity and greater atmospheric atomization output. To achieve atmospheric atomization, it is typically necessary to increase the liquid reservoir capacity in the electronic atomization device and employ a dual-electrode ceramic core (a ceramic core with dual heating elements) structure to enhance the atomization volume.

[0003] However, as the reservoir capacity increases, the internal hydraulic pressure rises significantly, creating continuous pressure on the atomizer core at the bottom of the e-cigarette. Especially during inhalation, the volume vacated in the reservoir due to the outflow of the aerosol matrix requires timely air replenishment to balance the pressure. If the air replenishment rate cannot keep up with the aerosol matrix supply flow rate, a negative pressure will be generated in the reservoir. This negative pressure, combined with the external atmospheric pressure, will create a strong siphon effect on the aerosol matrix, causing an excessive and rapid influx of aerosol matrix into the atomizer core of the e-cigarette.

[0004] This imbalance in liquid intake prevents the atomizing coil, especially those using traditional dual-coil ceramic coils, from atomizing the incoming aerosol matrix in a timely manner, causing the aerosol matrix to accumulate inside the coil. When the user inhales, the airflow passes through this accumulated liquid, producing an unpleasant gurgling sound, and may even cause the aerosol matrix to be directly inhaled, severely impacting the user experience and product reliability. Utility Model Content

[0005] The purpose of this application is to provide an electronic atomizing device to solve the technical problem that existing high-capacity, high-output electronic atomizing devices cause the liquid inlet speed to far exceed the atomization speed due to the combined effect of hydraulic pressure increase and internal negative pressure during suction, thereby leading to aerosol matrix accumulation and abnormal noise.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides an electronic atomizing device, comprising: Liquid storage tank; An atomizing assembly includes a ceramic core, a heating element, an electrode, and a bracket for mounting the electrode. The ceramic core has at least two atomizing sections for gathering and atomizing an aerosol matrix, and the heating element is provided at the bottom of each atomizing section. The bracket is located below the ceramic core, and the electrode is disposed on the bracket and extends onto the ceramic core, abutting against the heating element at the bottom of each atomizing section. The liquid storage chamber is provided with a mounting base, and the atomizing component is disposed in the mounting base; the mounting base is provided with a liquid inlet and a suction air channel, the suction air channel is connected to the atomizing component and connected to the nozzle of an electronic atomizing device outside the liquid storage chamber; the liquid inlet corresponds to the position of the atomizing part on the ceramic core and is used to guide the aerosol matrix in the liquid storage chamber to each of the atomizing parts of the ceramic core.

[0007] The beneficial effects of the electronic atomizing device provided in this application are as follows: Compared with the prior art, the electronic atomizing device of this application has at least two atomizing sections on the ceramic core for gathering and atomizing the aerosol matrix, and a heating element is set at the bottom of each atomizing section. Each heating element is supported and powered by two electrodes on the support below, thus forming a four-column support structure. This allows each atomizing section on the ceramic core to be the area where excess aerosol matrix first arrives and accumulates due to gravity and siphon effect. This ensures that aerosol matrix that flows in rapidly due to hydraulic and negative pressure imbalance will preferentially contact the high-temperature heating element and be instantly atomized, which helps reduce the accumulation of aerosol matrix and effectively reduces the "gurgling" noise.

[0008] In this application, the ceramic core of the electronic atomizing device has at least two atomizing parts, and heating elements are respectively provided at the bottom of the two atomizing parts, thereby forming a ceramic core structure with dual heating elements integrated. The four electrodes at the bottom (two for each heating element) provide uniform and stable support and upward pushing force, which helps to improve the sealing between the ceramic core and the mounting base, thereby reducing the risk of leakage due to sealing failure.

[0009] The structure of the ceramic core is improved by incorporating recessed liquid collection grooves on each atomizing section. The shape of the groove opening of each liquid collection groove is adapted to and corresponds to the position of each liquid inlet. Thus, the liquid collection grooves act as liquid reservoirs, capable of accommodating the aerosol matrix that suddenly accelerates due to suction negative pressure, buffering and temporarily storing unstable liquid inflow. This helps to buffer hydraulic fluctuations that directly impact the atomizing section, providing a stable liquid supply environment for the heating element located at the bottom of the atomizing section, and effectively preventing abnormal noises caused by excessive instantaneous liquid supply.

[0010] In one embodiment, the heating element includes an insertion portion extending into the ceramic core, the insertion portion being disposed around the outer periphery of the liquid collecting tank. This allows the heat emitted by the heating element to be transferred not only upwards from the bottom of the ceramic core but also simultaneously from the outer periphery of the liquid collecting tank to the center of the tank, thereby creating a three-dimensional heating effect on the aerosol matrix in the tank, effectively increasing the heating contact area and improving atomization efficiency.

[0011] In one embodiment, each of the liquid inlet holes of the mounting base is provided with a sealing ring, which is respectively arranged around the outer periphery of the opening of each liquid collection tank. The sealing ring is clamped between the inner wall of the mounting base and the ceramic core. In this way, the sealing ring precisely seals the connection between the liquid collection tank and the liquid inlet hole, effectively preventing the aerosol matrix from leaking directly from the assembly gap between the ceramic core and the mounting base under high pressure.

[0012] The structure of the support is improved by incorporating an upright liquid-gathering plate. The surface of the liquid-gathering plate is covered with multiple raised ribs, spaced apart to form liquid-gathering gaps. This utilizes the dense ribs and gaps on the liquid-gathering plate to actively adsorb and lock in the seeping liquid through capillary action. Dispersing and fixing the liquid within the gaps of the liquid-gathering plate helps reduce noise generated by airflow passing through the liquid.

[0013] In one embodiment, the support is further provided with a first liquid-absorbing element, and the liquid-collecting plate has a groove for mounting the first liquid-absorbing element, with at least a portion of the first liquid-absorbing element protruding from the opening of the groove. Thus, adding an embedded first liquid-absorbing element to the liquid-collecting plate helps to increase the liquid-absorbing area and liquid storage capacity of the liquid-collecting plate.

[0014] In one embodiment, the mounting base includes a first chamber for housing the ceramic core and a second chamber communicating with the first chamber, with the liquid-collecting plate on the support placed in the second chamber. This partitions the internal structure of the mounting base, preventing the disorderly spread of seepage dripping from the ceramic core within the open cavity at its bottom. The first chamber limits seepage to any corner, and the seepage is directed to the second chamber, where the liquid-collecting plate absorbs it, effectively reducing liquid accumulation and eliminating the possibility of abnormal noise.

[0015] In one embodiment, the mounting base further includes a third chamber adjacent to the second chamber, the third chamber being filled with a second liquid-absorbing element. In this way, any liquid that may leak from the second chamber is confined to the third chamber, where the leak is further absorbed by the third chamber and the second liquid-absorbing element disposed therein.

[0016] In one embodiment, the support also has a perforation communicating with the third chamber and a third liquid-absorbing element located below the support. Excess liquid absorbed by the second liquid-absorbing element seeps into the third liquid-absorbing element through the perforation. Thus, by utilizing the perforation on the support, the second and third liquid-absorbing elements located in the third chamber are interconnected and share the liquid absorption, effectively improving the liquid absorption effect.

[0017] The structure of the support is further improved by adding a frame and multiple electrode holes within the frame for mounting the electrodes. Each electrode passes through its respective electrode hole. The upper end of each electrode abuts against the heating element at the bottom of the ceramic core, and the lower end extends from below the support and is electrically connected to the power supply component of the electronic atomization device. Thus, the electrode holes within the frame of the support help prevent lateral displacement or wobbling of the electrodes, ensuring that the four electrodes can push upwards vertically and evenly, effectively improving the stability of the ceramic core support.

[0018] In one embodiment, the electronic atomizing device further includes a microphone airflow channel located below the support and communicating with the microphone of the electronic atomizing device. The support has a pair of guide channels that communicate with the microphone airflow channel respectively. The pair of guide channels are symmetrically arranged within the frame, and one end port of each of the pair of guide channels corresponds one-to-one with the position of each atomizing part on the ceramic core. In this way, by aligning the ports of the guide channels with each atomizing part, the microphone can accurately detect changes in negative pressure, effectively ensuring trigger sensitivity.

[0019] In one embodiment, the support is further provided with a fourth liquid-absorbing element on one side of the microphone airway. The fourth liquid-absorbing element fills the space between the frame and each of the electrodes, and is respectively arranged around the other end ports of the pair of flow channels. In this way, the fourth liquid-absorbing element can quickly absorb the liquid flowing out from the other end ports of the pair of flow channels, effectively preventing liquid from entering the microphone airway.

Detailed Implementation

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0025] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0026] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0027] To increase the aerosol output of electronic atomizers, it's typically necessary to increase the reservoir capacity and employ a dual-heating ceramic core to enhance atomization efficiency. However, increasing the reservoir capacity directly leads to an increase in internal liquid pressure, which continuously acts on the bottom of the atomizer core. Furthermore, during inhalation, as the aerosol matrix flows out, the reservoir needs to be replenished with air to maintain pressure balance. If the air compensation rate is lower than the aerosol matrix flow rate, it means the aerosol matrix is ​​flowing too fast, creating a negative pressure environment within the reservoir. This negative pressure, combined with the external atmospheric pressure, triggers a strong siphon effect, causing an excessive and rapid influx of aerosol matrix into the atomizer core. This imbalance between liquid supply and atomization makes it difficult for traditional dual-heating ceramic cores to effectively and promptly atomize the incoming aerosol matrix, resulting in aerosol matrix accumulation within the atomizer core. When the user inhales again, the airflow will produce a noticeable "gurgling" sound as it passes through the aerosol matrix accumulation area. In severe cases, the un-atomized aerosol matrix may be directly inhaled into the user's mouth, seriously affecting the user's comfort and reducing the overall reliability of the product.

[0028] Therefore, this application provides a novel electronic atomizing device, which improves the dual-electrode ceramic core and electrode connection structure in the atomizing component. This effectively solves the problem that traditional high-capacity, high-output electronic atomizing devices suffer from a liquid inlet speed that far exceeds the atomization speed due to the combined effect of increased hydraulic pressure and internal negative pressure during suction, which leads to aerosol matrix accumulation, "gurgling" noise, and leakage. The details are described below.

[0029] Please see Figure 1 The electronic atomizing device includes an atomizing part and a power supply part. The atomizing part includes an atomizing component 100 and a liquid storage tank 200. The power supply part has a power supply component 300, which is electrically connected to the atomizing component 100 through electrodes in the atomizing component 100.

[0030] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The atomizing assembly 100 includes a ceramic core 1, a heating element 2, an electrode 3, and a bracket 4 for mounting the electrode 3. The ceramic core 1 has at least two atomizing sections 11 for gathering and atomizing the aerosol matrix, and a heating element 2 is provided on the bottom of each atomizing section 11. In this embodiment, the ceramic core 1 has two atomizing sections 11, and a heating element 2 is provided on the bottom of each of the two atomizing sections 11, thereby forming a ceramic core 1 with a dual heating element integrated into one piece. The heating element 2 can preferably be a heating wire, and the shape of the heating wire matches the atomizing section 11 and is arranged on the bottom of the atomizing section 11, thereby atomizing the aerosol matrix gathered on the atomizing section 11 and producing aerosol.

[0031] like Figure 3 and Figure 4As shown, the support 4 is located below the ceramic core 1, and the electrodes 3 are disposed on the support 4 and extend towards the ceramic core 1, contacting the heating elements 2 at the bottom of each atomizing section 11. The number of electrodes 3 corresponds to the number of heating elements 2, and each heating element 2 is electrically in contact with two electrodes 3. In this embodiment, the support 4 has two sets of electrodes 3, each set having two electrodes 3, and each pair of electrodes 3 is supported by one heating element 2, thus forming a "four-column support structure" at the bottom of the ceramic core 1, which helps improve the stability of the support for the dual-electrode ceramic core 1.

[0032] Please refer to the following: Figure 2 , Figure 3 and Figure 4 The liquid storage tank 200 is provided with a mounting base 5, and the atomizing component 100 is installed in the mounting base 5. The mounting base 5 is provided with a liquid inlet 51 and a suction air passage 52. The suction air passage 52 is connected to the atomizing component 100 and is connected to the nozzle of the electronic atomizing device outside the liquid storage tank 200.

[0033] The number of liquid inlet holes 51 is the same as the number of atomizing parts 11 on the ceramic core 1, and corresponds to the position of each atomizing part 11 on the ceramic core 1. In this embodiment, the liquid inlet holes 51 are arranged around the suction air passage 52 to improve the layout compactness. Each liquid inlet hole 51 is used to guide the aerosol matrix in the liquid storage tank 200 to each atomizing part 11 of the ceramic core 1.

[0034] It can be seen that, as Figure 5 As shown, the bracket 4 abuts against the two electrodes 3 on the bottom of the ceramic core 1 through two sets of electrodes 3 respectively, thereby forming a "four-column support structure" on the bottom of the ceramic core 1. This "four-column support structure" can stably push the large-area dual-electrode ceramic core 1 onto the inner top wall of the mounting base 5, making it less prone to tilting and effectively improving the support effect on the dual-electrode ceramic core 1.

[0035] Compared with the prior art, the electronic atomizing device provided in this application embodiment has at least two atomizing sections 11 on the ceramic core 1 for gathering and atomizing the aerosol matrix, and a heating element 2 is provided at the bottom of each atomizing section 11. Each heating element 2 is supported and powered by two electrodes 3 on the lower support 4, thereby forming a four-column support structure. This allows each atomizing section 11 on the ceramic core 1 to be the area where excess aerosol matrix first arrives and accumulates due to gravity and siphon effect. This ensures that aerosol matrix that flows in rapidly due to hydraulic and negative pressure imbalance will preferentially contact the high-temperature heating element 2 and be instantly atomized, which helps reduce the accumulation of aerosol matrix and effectively reduces the "gurgling" noise.

[0036] Traditional methods using two independent ceramic cores 1 have two separate mounting and sealing points, resulting in a loose structure that is prone to problems such as poor sealing or poor contact due to vibration or assembly errors. In the electronic atomizing device provided in this application embodiment, the ceramic core 1 has at least two atomizing sections 11, and heating elements 2 are respectively disposed at the bottom of the two atomizing sections 11, thus forming a dual-heating integrated ceramic core 1 structure. The four electrodes 3 at the bottom (two for each heating element 2) provide uniform and stable support and upward pushing force, which helps improve the sealing between the ceramic core 1 and the mounting base 5. Under any circumstances (such as oil pressure changes, temperature changes, slight vibrations, etc.), it can maintain tight contact, effectively reducing the risk of leakage due to sealing failure.

[0037] Among them, the four electrodes 3 in the above-mentioned four-column support structure provide redundant and stable current paths, effectively preventing situations such as tripping or power failure caused by vibration during transportation or use, thereby ensuring that the dual heating elements 2 can work continuously and stably.

[0038] The ceramic core 1 provided in this embodiment has at least two independent atomizing sections 11, and each atomizing section 11 is provided with a corresponding number of liquid inlet holes 51 on the mounting base 5 to independently supply liquid, effectively ensuring that the oil supply environment and airflow environment of each atomizing section 11 are highly consistent. Simultaneously, the heating elements 2 provided at the bottom of each atomizing section 11 provide synchronous heating, effectively ensuring that the two heating elements 2 atomize an equal amount of aerosol matrix with the same efficiency, avoiding the imbalance problem that may occur with traditional independent dual-electrode ceramic cores 1, where one core is dry-burning and the other is flooded. Therefore, the electronic atomizing device of this embodiment can output a consistent flavor and a balanced amount of aerosol during use, thereby improving the user experience.

[0039] Furthermore, the dual-heating integrated ceramic core 1 provided in this application embodiment integrates the complex dual-electrode system into a single component. The bottom is supported and electrically connected via a bracket 4 and four electrodes 3, effectively simplifying the assembly process and improving production efficiency and product consistency. Simultaneously, the compact layout provides more usable space for the liquid storage tank 200 and the suction airway 52, which is beneficial for optimizing the internal layout of the high-capacity, high-output electronic atomizing device provided in this application embodiment.

[0040] For the specific structure of the ceramic core 1, please refer to one embodiment of this application. Figure 5 and Figure 6 The ceramic core 1 has a liquid collection groove 12 recessed on each atomizing part 11, and the shape of the groove of each liquid collection groove 12 is adapted to each liquid inlet 51 and the position corresponds to it.

[0041] In this embodiment, the ceramic core 1 is preferably a cuboid structure, and two symmetrically arranged liquid collection grooves 12 are formed on the upper surface of the ceramic core 1. The two liquid collection grooves 12 are preferably rectangular grooves to maximize the utilization of the cross-sectional area on the ceramic core 1. Correspondingly, the mounting base 5 has two liquid inlet holes 51 that match the positions of the liquid collection grooves 12. The shape and orifice size of the liquid inlet holes 51 are adapted to the liquid collection grooves 12.

[0042] Therefore, the liquid collection tank 12, as a miniature liquid storage pool, can instantly receive the aerosol matrix that suddenly accelerates down due to the negative pressure of suction, playing a role in buffering and temporarily storing unstable liquid. This helps to buffer the hydraulic fluctuations that directly impact the atomizing section 11, providing a stable liquid supply environment for the heating element 2 located at the bottom of the atomizing section 11, and effectively preventing the "gurgling" noise caused by excessive instantaneous liquid supply.

[0043] Regarding the structure of the heating element 2 on the ceramic core 1, please refer to one embodiment of this application. Figure 7 and Figure 8 The heating element 2 includes an insertion portion 21 extending into the ceramic core 1 from the bottom, the insertion portion 21 being disposed around the outer periphery of the liquid collection tank 12.

[0044] In this embodiment, as Figure 8 As shown, two heating elements 2 are provided at the bottom of the ceramic core 1, corresponding to the positions of the liquid collection tanks 12 of the two atomizing parts 11. The heating elements 2 can preferably be heating elements with a U-shaped cross-section. At least two sides of the heating elements 2 have bent insertion parts 21 for insertion into the ceramic core 1, so that the insertion parts 21 are located on the symmetrical sides of the liquid collection tanks 12.

[0045] The body of the heating element 2 is located at the bottom of the ceramic core 1, and has two contact plates 22 for contacting the electrode 3. A mesh-like connecting wire 23 is located between the two contact plates 22. Figure 7 As shown, the contact plates 22 on the two heating elements 2 are arranged in a rectangular pattern on the lower surface of the ceramic core 1, forming a four-column support structure after contacting the four electrodes 3. This allows the electrodes 3 to stably and with a large area against the contact plates 22, effectively ensuring the stability of the electrical connection and helping to solve problems such as resistance skipping or arcing that easily occur when there is point contact between the heating wire and the electrodes 3 in traditional heating elements. The four electrodes 3 push upwards against the four contact plates 22 on the two heating elements 2. This pushing force is evenly transmitted to the entire heating element 2 and the ceramic core 1 it is embedded in, thus forming a stable support structure. This helps to improve the fixing effect of the ceramic core 1 and effectively ensures the stability of the installation of the ceramic core 1.

[0046] In this way, the heat emitted by the heating element 2 is not only transferred upwards from the bottom of the ceramic core 1, but also simultaneously conducted from the outer periphery of the liquid collection tank 12 to the center of the liquid collection tank 12, thereby forming a three-dimensional heating of the aerosol matrix in the liquid collection tank 12, effectively increasing the heating contact area and improving atomization efficiency. Especially in the case of excessively rapid liquid inflow, it can atomize in time, which helps to eliminate the "gurgling" noise caused by liquid accumulation.

[0047] Preferably, such as Figure 9 As shown, the mounting base 5 is also provided with a sealing sleeve 53, which is used to seal the surface of the mounting base 5 (located on one side of the liquid storage tank 200) and the gap between the mounting base 5 and the outer shell, effectively improving the sealing effect. The sealing sleeve 53 has an opening 531 that matches the position of the liquid inlet 51, so as to ensure that the aerosol matrix in the liquid storage tank 200 can reach the atomizing part 11 of the ceramic core 1 through the liquid inlet 51.

[0048] Regarding the mounting position between the liquid inlet 51 on the mounting base 5 and the atomizing part 11 on the ceramic core 1, please refer to the embodiments of this application. Figure 9 , Figure 10 and Figure 11 The mounting base 5 is provided with sealing rings 54 located on each liquid inlet hole 51. The sealing rings 54 are respectively arranged around the outer periphery of the groove opening of each liquid collection tank 12. The sealing rings 54 are clamped between the inner wall of the mounting base 5 and the ceramic core 1.

[0049] In this embodiment, the sealing ring 54 can preferably be a rectangular silicone ring so that the shape of the sealing ring 54 matches the shape of the inlet hole 51 and the groove of the collection tank 12, and has a soft sealing performance.

[0050] Preferably, such as Figure 10 and Figure 11 As shown, the inner top wall of the mounting base 5 has a mounting groove 55 surrounding the outer periphery of the liquid inlet hole 51, and the sealing ring 54 is embedded in the mounting groove 55. The mounting groove 55 is used to lock the installation position of the sealing ring 54, preventing it from shifting or falling off during assembly, effectively ensuring the sealing consistency of each assembly, and thus improving the product yield.

[0051] In addition, combined with the above-mentioned "four-column support structure", the uniform and stable upward pushing force provided by the four electrodes 3 ensures that the entire surface of the ceramic core 1 can flatly press the sealing ring 54, thereby forming a sealing band with uniform pressure, effectively avoiding local leakage caused by uneven force.

[0052] In this way, the connection between the liquid collection tank 12 and the liquid inlet 51 is sealed by the sealing ring 54, which effectively prevents the aerosol matrix from leaking directly from the assembly gap between the ceramic core 1 and the mounting base 5 under high pressure. In practical applications, the dual-electrode ceramic core 1, due to its large size, may experience excessive leakage in areas other than its atomizing section 11. Furthermore, the compact structure of the hollowed-out area between the bottom of the ceramic core 1 and the four electrodes 3 makes it easy for the leaked aerosol matrix to accumulate, leading to a gurgling sound.

[0053] Therefore, regarding the structure on the bracket 4, please refer to one embodiment of this application. Figure 12 The support 4 is provided with an upright liquid collection plate 41. The surface of the liquid collection plate 41 is distributed with multiple ribs 411, and the ribs 411 are spaced apart to form liquid collection gaps 412.

[0054] In this embodiment, the support 4 is provided with a pair of symmetrically arranged liquid-gathering plates 41. Each liquid-gathering plate 41 has a door frame structure, and a plurality of raised ribs 411 are distributed on the surface of the liquid-gathering plate 41. These ribs 411 can be strip-shaped or square-shaped, and are not specifically limited here. The ribs 411 are spaced apart, thereby forming liquid-gathering gaps 412 between adjacent ribs 411. Preferably, the isolation distance between the ribs 411 is the same, so that the width of each liquid-gathering gap 412 is the same, which is beneficial to improving the uniformity of liquid gathering.

[0055] In this way, by utilizing the dense ribs 411 on the liquid-collecting plate 41 and the liquid-collecting gaps 412, the seeping liquid is actively adsorbed and locked in through capillary action. The liquid is dispersed and fixed in the liquid-collecting gaps 412 of the liquid-collecting plate 41, which helps to reduce the "gurgling" noise caused by airflow passing through the liquid.

[0056] In addition, the liquid-absorbing plate 41 absorbs the seepage, effectively preventing the liquid from forming bridges among the four electrodes 3, avoiding the risk of short circuits caused by liquid conductivity, and ensuring the long-term stability and safety of the power supply to the electrodes 3 in the four-column support structure.

[0057] Please see Figure 12 The bracket 4 is also provided with a first liquid suction member 42, and the liquid collection plate 41 is provided with a groove 413 for installing the first liquid suction member 42, and at least a part of the first liquid suction member 42 is exposed at the opening of the groove 413.

[0058] In this embodiment, the first absorbent element 42 can preferably be made of absorbent cotton, and the side of the liquid collection plate 41 has a groove 413 for mounting the first absorbent element 42, allowing the first absorbent element 42 to be completely embedded in the groove 413. Figure 12 As shown, the groove 413 can preferably be a rectangular groove, and the first absorbent member 42 is fitted with it as a rectangular plate-shaped absorbent cotton. After the first absorbent member 42 is fully embedded in the groove 413, one side plate of the first absorbent member 42 is exposed on the groove opening of the groove 413.

[0059] Therefore, adding an embedded first liquid-absorbing element 42 to the liquid-collecting plate 41 is beneficial to increasing the liquid-absorbing area and liquid storage capacity on the liquid-collecting plate 41.

[0060] The internal structure of the mounting base 5 has been optimized. Please refer to one embodiment of this application for further details. Figure 11 , Figure 12 and Figure 13 The mounting base 5 includes a first chamber 56 for accommodating the ceramic core 1 and a second chamber 57 communicating with the first chamber 56. The liquid collection plate 41 on the bracket 4 is placed in the second chamber 57.

[0061] In this embodiment, as Figure 13 As shown, the second chambers 57 are located on both sides of the first chamber 56, and a partition is provided between the second chambers 57 and the first chamber 56. A grid-like liquid-guiding structure 58 is formed on the partition to allow communication between the first chamber 56 and the two second chambers 57. Preferably, the liquid-collecting plate 41 on the support 4 is housed within the second chamber 57 and is located within the coverage area of ​​the liquid-guiding structure 58, so that the exudate present in the first chamber 56 can quickly reach the liquid-collecting plate 41 in the second chamber 57 through the liquid-guiding structure 58.

[0062] In this way, the internal structure of the mounting base 5 is divided to prevent the seepage dripping from the ceramic core 1 from spreading disorderly in an open cavity at its bottom. The first chamber 56 is used to limit the seepage to any corner and guide the seepage to the second chamber 57 connected to the first chamber 56. The liquid collection plate 41 in the second chamber 57 absorbs the seepage, effectively reducing the liquid volume and eliminating the possibility of abnormal noise.

[0063] In actual assembly, such as Figure 14 As shown, the partition structure inside the mounting base 5 that connects to the bracket 4 may have microscopic gaps M at the interface due to the manufacturing tolerances and assembly clearances of the plastic parts. These gaps can become unintended leakage paths during use, thus posing a risk of seal failure.

[0064] In view of the above, please refer to one embodiment of this application. Figure 13 and Figure 14 The mounting base 5 also includes a third chamber 59 adjacent to the second chamber 57, and the third chamber 59 is filled with a second liquid suction element 591.

[0065] In this embodiment, a second chamber 57 communicating with the first chamber 56 is provided on both sides of the first chamber 56. A third chamber 59 is formed on the outer side of the second chamber 57 away from the first chamber 56 by a partition structure. A second liquid absorbent 591 is provided in the third chamber 59. The second liquid absorbent 591 can preferably be a liquid absorbent cotton, and the second liquid absorbent 591 is preferably arranged to fill the inner cavity of the third chamber 59.

[0066] In this way, any liquid that may leak from the second chamber 57 is restricted to the third chamber 59, where the leak is further absorbed by the third chamber 59 and the second liquid-absorbing element 591 installed inside it.

[0067] Based on the above, in one embodiment of this application, please refer to Figure 14 The support 4 is also provided with a perforation 44 communicating with the third chamber 59 and a third liquid suction member 43 located below the support 4. Excess liquid absorbed by the second liquid suction member 591 in the third chamber 59 can seep into the third liquid suction member 43 through the perforation 44.

[0068] In this embodiment, the third absorbent element 43 below the support 4 can preferably be made of absorbent cotton. The support 4 is also provided with a perforation 44, and at least a portion of the third absorbent element 43 is located on the perforation 44, so that the second absorbent element 591 and the third absorbent element 43 in the third chamber 59 can communicate with each other through the perforation 44.

[0069] In this way, by utilizing the perforation 44 on the support 4, the second liquid suction member 591 located in the third chamber 59 and the third liquid suction member 43 located below the support 4 can communicate with each other and share the liquid suction volume, thereby effectively improving the liquid suction effect.

[0070] For the structure on bracket 4, please refer to another embodiment of this application. Figure 1 and Figure 15 The bracket 4 is also provided with a frame 45 and a plurality of electrode holes 46 located within the frame 45 for mounting electrodes 3 respectively. Each electrode 3 is connected to the respective electrode hole 46. The upper end of the electrode 3 abuts against the heating element 2 on the bottom of the ceramic core 1, and the lower end of the electrode 3 extends from the bottom of the bracket 4 and is used for electrical connection with the power supply component 300.

[0071] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 15 As shown, the bracket 4 is located between the ceramic core 1 and the power supply component 300. Within the surrounding area of ​​the bracket 45, four electrode holes 46, the same number as the electrodes 3, are provided. The four electrodes 3 are respectively inserted into each electrode hole 46. The positions of the four electrode holes 46 correspond one-to-one with the positions of the four contact plates 22 on the heating element 2 at the bottom of the ceramic core 1. This facilitates the rapid and precise guidance of the electrodes 3 to the target position during assembly, effectively improving production efficiency and product consistency.

[0072] Furthermore, the upper ends of each electrode 3 extend to the bottom of the ceramic core 1 and contact the heating element 2, while the lower ends of the electrodes 3 extend to the area where the power supply component 300 of the electronic atomizing device is located. For example... Figure 1As shown, the power supply assembly 300 may include a main control board 301 and a battery 302 that supplies power to the atomizing assembly 100. The main control board 301 and the battery 302 are electrically connected. The lower ends of each electrode 3 can be electrically connected to the main control board 301 via cables.

[0073] Therefore, electrode holes 46 for installing electrodes 3 are provided inside the frame 45 of the bracket 4, which helps to prevent the electrodes 3 from shifting or shaking laterally, and ensures that the four electrodes 3 can be pushed upward vertically and evenly, effectively improving the stability of the support for the ceramic core 1.

[0074] Based on the above, please refer to the embodiments in this application as well. Figure 16 and Figure 17 The electronic atomizing device provided in this application embodiment also includes a microphone airway 61 located below the bracket 4 and used to communicate with the microphone 6 in the electronic atomizing device. The microphone 6 in the electronic atomizing device can be understood as an airflow sensor used to sense the user's inhalation action.

[0075] The bracket 4 has a pair of flow channels 47 that are connected to the microphone airway 61. The pair of flow channels 47 are symmetrically arranged within the frame 45. One end of the pair of flow channels 47 corresponds to the position of each atomizing part 11 on the ceramic core 1.

[0076] In this way, on the one hand, the port of the airflow channel 47 is aligned with each atomizing part 11 so that the microphone 6 can collect the air pressure signal of the area where the airflow is most active and the negative pressure is most significant at the moment of atomization. This ensures that no matter how the user holds the microphone or inhales, the microphone 6 can accurately capture the change in negative pressure, effectively ensuring the triggering speed and triggering sensitivity.

[0077] On the other hand, slight airflow differences may exist on the dual-heating ceramic core 1, causing one area to be detected by the microphone 6 before the other. Therefore, in this embodiment, a pair of symmetrically arranged guide channels 47 are provided within the frame 45 of the bracket 4, corresponding to the two independent atomizing sections 11 and heating elements 2 on the ceramic core 1, respectively. This ensures that the air pressure signals from the two heating elements 2 can be transmitted synchronously and accurately to the microphone 6, effectively improving the uniformity of the atomizing assembly 100 using the dual-heating ceramic core 1 in terms of operational perception, thereby improving atomization uniformity.

[0078] In practical applications, since the inlets of the aforementioned pair of guide channels 47 are positioned directly opposite the atomizing unit 11, although the most accurate air pressure signal can be collected, it also exposes it to risks. In extreme cases, incompletely atomized droplets or a large amount of condensate may be drawn into the guide channels 47.

[0079] Therefore, in one embodiment of this application, please refer to [the relevant documentation / reference]. Figure 17 and Figure 18 The bracket 4 is located on one side of the microphone airway 61 and is also provided with a fourth liquid suction element 48. The fourth liquid suction element 48 fills the space between the frame 45 and each electrode 3, and is respectively arranged around the other end port of a pair of guide channels 47.

[0080] In this embodiment, as Figure 18 As shown, a fourth liquid-absorbing element 48 is provided on the side of the support 4 away from the ceramic core 1 (i.e., the side located in the microphone airway 61). The fourth liquid-absorbing element 48 can preferably be a liquid-absorbing cotton. The fourth liquid-absorbing element 48 has a through hole 481 around the port on the other end of a pair of guide channels 47 and is filled in the frame 45 and between the four electrodes 3 to effectively absorb the liquid that may flow out from the guide channels 47.

[0081] In this way, the fourth liquid suction element 48 can quickly absorb the liquid flowing out from the other end of the pair of guide channels 47, effectively preventing the liquid from entering the microphone airway 61.

[0082] In addition, the fourth liquid-absorbing element 48 is filled within the frame 45 and between the four electrodes 3, serving as an insulator. This helps increase the creepage distance between the electrodes 3 and occupies space that could potentially form liquid conductive paths, preventing the formation of liquid bridges between the electrodes 3 and effectively ensuring the electrical safety of the four-column support structure.

[0083] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
