Description

Technical Field

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

[0002] Electronic atomizing devices are used to heat an aerosol matrix to generate aerosols for user use. In existing technologies, electronic atomizing devices heat the aerosol matrix through an atomizing core. However, the atomizing core is usually designed as a single-electrode structure, resulting in a relatively small amount of aerosol produced during the atomization process, which cannot meet the user's needs. Utility Model Content

[0003] This application provides an atomizing core and an atomizing device, aiming to solve the technical problem of insufficient atomization volume of aerosol generated during atomization in existing electronic atomizing devices.

[0004] Some embodiments of this application provide an atomizing core, including:

[0006] A liquid-guiding assembly, installed on the outer side of the tube wall, is used to adsorb the aerosol matrix; and,

[0007] The heating element includes a plurality of heating elements, which are spaced apart on the inner side of the tube wall along the extension direction of the atomizing tube. The heating elements are used to heat and atomize the aerosol matrix.

[0008] The tube wall has multiple hollowed-out portions arranged along the extension direction of the atomizing tube, and at least one hollowed-out portion is correspondingly provided in a heating element along the length of the extension direction. At least a portion of the heating element contacts the liquid guiding element through the hollowed-out portions.

[0009] In some embodiments, the liquid guiding assembly includes multiple liquid guiding elements with different adsorption forces;

[0010] Multiple liquid guiding elements are arranged along the extension direction of the atomizing tube, with adjacent liquid guiding elements in contact with each other. Along the direction of gravity, the upper liquid guiding element has a greater adsorption force on the aerosol matrix than the lower liquid guiding element, so as to counteract at least part of the gravity of the aerosol matrix adsorbed by the upper liquid guiding element.

[0011] In some embodiments, the lower liquid guiding element has a plurality of first capillary pores, and the upper liquid guiding element has a plurality of second capillary pores;

[0012] The density of the second capillary pores is greater than the density of the first capillary pores; and / or,

[0013] The diameter of the second capillary is smaller than that of the first capillary.

[0014] In some embodiments, the upper liquid guiding element is made of non-woven fabric, porous ceramic, fiber, sponge or water-absorbing polymer, and the lower liquid guiding element is made of non-woven fabric, porous ceramic, fiber, sponge or water-absorbing polymer.

[0015] The adsorption force of the liquid guiding material located above is greater than that of the liquid guiding material located below.

[0016] In some embodiments, the heating power of the plurality of heating elements arranged at intervals along the direction of gravity gradually increases.

[0017] In some embodiments, the heating component further includes a liquid conductor;

[0018] The adsorption force of the liquid guiding the aerosol matrix is ​​greater than or equal to the adsorption force of the liquid guiding component on the aerosol matrix. The liquid guiding is disposed between the heating element and the tube wall along the extension direction of the atomizing tube. The liquid guiding contacts the liquid guiding component through the hollow part. All of the heating elements are in contact with the liquid guiding.

[0019] In some embodiments, the atomizing core further includes an atomizing cover;

[0020] The sidewall of the atomizing cover is provided with a plurality of liquid passage holes, which are disposed on the outer periphery of the liquid guiding component. The atomizing cover and the atomizing tube form a receiving cavity, the liquid guiding component is disposed in the receiving cavity, and the inner surface of the liquid guiding component is in contact with the outer wall of the atomizing tube, and the outer surface of the liquid guiding component is in contact with the inner wall of the atomizing cover.

[0021] Some embodiments of this application also provide an atomizing device, characterized in that it includes:

[0022] The atomizing core described in any of the above embodiments;

[0023] A liquid reservoir assembly for supplying the aerosol matrix to the atomizing core; and,

[0024] A power supply component is electrically connected to the atomizing core, and the power supply component is used to supply power to the atomizing core.

[0025] In some embodiments, the power supply component includes a first electrode and a plurality of second electrodes;

[0026] Each of the heating elements has two pins, one of which is electrically connected to the first electrode, and the other pin of each heating element is electrically connected to a plurality of the second electrodes.

[0027] In some embodiments, the liquid storage assembly includes a liquid storage chamber, a liquid passage chamber, and a sealing element;

[0028] The liquid storage chamber is connected to the liquid passage chamber. The sealing element is disposed between the liquid storage chamber and the liquid passage chamber to control the opening or closing of the liquid storage chamber. The liquid storage chamber is used to store the aerosol matrix, the liquid passage chamber is used to receive the aerosol matrix, and the atomizing core is used to heat the aerosol matrix from the liquid passage chamber.

[0029] According to the atomizing core in the above embodiments, by arranging multiple heating elements at intervals along the extension direction of the atomizing tube within the atomizing core, not only can the contact area between the aerosol matrix and the heating elements be increased, but the problem of localized overheating and damage to the liquid guiding assembly due to excessively close proximity of multiple heating elements can also be avoided. Simultaneously, the liquid guiding assembly is installed on the outer side of the tube wall, and multiple perforated sections are provided along the extension direction of the atomizing tube, ensuring that each heating element corresponds to at least one perforated section. This not only utilizes the atomizing tube to fix the liquid guiding assembly, but also allows the aerosol matrix adsorbed within the liquid guiding assembly to flow through the multiple perforated sections to each corresponding heating element during atomization. This ensures that each heating element can heat and atomize the aerosol matrix during operation, thereby increasing the atomization volume when the atomizing core generates aerosol, thus meeting the user's needs.

For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0042] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0043] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0044] This application provides an atomizing device, such as... Figure 1 and Figure 2 As shown, the atomizing device may include a liquid storage component 1, an atomizing core 2, and a power supply component 3. The liquid storage component 1 can be used to store the aerosol matrix and provide heating to the atomizing core 2 to generate aerosol. The power supply component 3 is electrically connected to the atomizing core 2 and is used to supply power to the atomizing core 2. The atomizing device can be a disposable product, that is, the liquid storage component 1, the atomizing core 2, and the power supply component 3 can be packaged in the same housing. Alternatively, the atomizing device can also be a replaceable product, that is, the liquid storage component 1, the atomizing core 2, and the power supply component 3 can be packaged in different housings, and the different housings can be detachably connected by screws, plugs, or magnetic attraction, so that the liquid storage component 1 and / or the atomizing core 2 can be replaced according to the user's needs. This application does not impose any special limitations on the specific structure of the atomizing device.

[0045] In some embodiments, such as Figure 2 and Figure 3 As shown, the liquid storage assembly 1 may include a housing 11, a support 12, a first seal 13, and a second seal 14. The support 12 is installed inside the housing 11, and the first seal 13 is installed between the support 12 and the housing 11, forming a liquid storage cavity 15 between the first seal 13 and the housing 11. The liquid storage cavity 15 is used to store the aerosol matrix. The second seal 14 is installed on the side of the support 12 opposite to the first seal 13, forming a liquid passage cavity 16 between the first seal 13, the support 12, and the second seal 14. The liquid passage cavity 16 is used to receive the aerosol matrix. The first seal 13 is provided with a liquid passage 17, and the liquid storage cavity 15 communicates with the liquid passage cavity 16 through the liquid passage 17, allowing the aerosol matrix stored in the liquid storage cavity 15 to flow into the liquid passage cavity 16 under gravity. In addition, the atomizing device may also include a blocking element 4 and an actuating component 5. The blocking element 4 passes through the liquid passage 16 and the liquid channel 17, so that the blocking element 4 is disposed between the liquid storage chamber 15 and the liquid passage 16. The actuating component 5 is connected to one end of the blocking element 4 and is used to drive the blocking element 4 to move axially along the liquid passage 17. The other end of the blocking element 4 is used to open or close the liquid passage 17.

[0046] The actuation component 5 may include a knob and a cam. The knob is rotatably mounted on the housing 11, and the cam is connected to the knob. When the user rotates the knob, the knob drives the cam to rotate. The cam drives the sealing member 4 to move axially along the liquid passage 17 through a protruding part, thereby opening or closing the liquid passage 17 and controlling the flow of the aerosol matrix in the liquid storage chamber 15 into the liquid passage chamber 16. In other embodiments, the actuation component 5 may also be configured as a structure including a toggle and a connecting rod. The toggle is slidably connected to the housing 11, and the two ends of the connecting rod are respectively connected to the toggle and the sealing member 4, allowing the user to toggle the toggle along a straight line on the housing 11. The toggle drives the sealing member 4 to move up and down through the connecting rod, thereby opening or closing the liquid passage 17. This application does not impose any special limitations on the specific structure of the actuation component 5.

[0047] In addition, such as Figure 2 and Figure 3 As shown, the power supply component 3 may include a circuit board 31 and a battery cell 32. The atomizing core 2 passes through the first sealing member 13 and is electrically connected to the circuit board 31. The circuit board 31 is electrically connected to the battery cell 32, so that the battery cell 32 can supply power to the atomizing core 2 through the circuit board 31. To enrich the functionality of the atomizing core 2, the power supply component 3 may also include electronic components such as a controller, a charging interface, and an airflow sensor, all of which are electrically connected to the circuit board 31. The controller can be used to control the heating power of the atomizing core 2, the charging interface can be used to connect an external power source to charge the battery cell 32, and the airflow sensor can be used to sense changes in airflow when the user uses the atomizing core 2. This application does not impose any special limitations on the specific structure of the power supply component 3.

[0048] It is understood that the atomizing device of this application is not limited to having a liquid storage chamber 15 and a liquid passage chamber 16 in the liquid storage component 1. In other embodiments, the liquid storage component 1 can also be configured as an independent liquid storage tank for storing the aerosol matrix, and a portion of the atomizing core 2 can be directly disposed in the liquid storage tank, so that the aerosol matrix in the liquid storage tank can flow into the atomizing core 2 for heating and atomization. The portion of the atomizing core 2 located outside the liquid storage tank can be electrically connected to the power supply component 3, so that the power supply component 3 can supply power to the atomizing core 2. This application does not impose any special restrictions on the specific structure of the liquid storage component 1.

[0049] The above embodiments describe the overall structure of the atomizing device. To address the problem of insufficient atomization volume of the atomizing device during atomization, this application also provides an atomizing core 2, such as... Figure 4 and Figure 5As shown, the atomizing core 2 may include a liquid guiding component 21, a heating component 22, and an atomizing tube 23. The atomizing tube 23 has a tube wall. The liquid guiding component 21 is installed on the outside of the tube wall and can be used to adsorb the aerosol matrix. The heating component 22 may include a plurality of heating elements 221, which are spaced apart on the inside of the tube wall along the extension direction of the atomizing tube 23. The heating elements 221 can be used to heat and atomize the aerosol matrix. The tube wall has a plurality of hollowed-out portions 230 arranged along the extension direction of the atomizing tube 23. At least one hollowed-out portion 230 is correspondingly provided within the length range of the extension direction of a heating element 221. At least a portion of the heating component 22 is in contact with the liquid guiding component 21 through the hollowed-out portion 230.

[0050] This application, by arranging multiple heating elements 221 at intervals along the extension direction of the atomizing tube 23 within the atomizing core 2, not only increases the contact area between the aerosol matrix and the heating elements 221, but also avoids the problem of localized overheating and damage to the liquid guiding assembly 21 due to excessively close proximity of multiple heating elements 221. Simultaneously, by installing the liquid guiding assembly 21 on the outer side of the tube wall and providing multiple perforated portions 230 along the extension direction of the atomizing tube 23, ensuring that each heating element 221 corresponds to at least one perforated portion 230, the atomizing tube 23 not only serves to fix the liquid guiding assembly 21, but also allows the aerosol matrix adsorbed within the liquid guiding assembly 21 to flow through the multiple perforated portions 230 to each corresponding heating element 221 during atomization. This ensures that each heating element 221 can heat and atomize the aerosol matrix during operation, thereby increasing the atomization volume of the atomizing core 2 when generating aerosols to meet user needs.

[0051] Among them, such as Figure 5 As shown, the perforated portion 230 on the wall of the atomizing tube 23 can be configured as a through-hole structure with a rectangular, circular, or waist-shaped form. Along the extension direction of the atomizing tube 23, multiple perforated portions 230 can be configured with the same or different shapes to match the flow velocity of the aerosol matrix at different positions along the extension direction of the atomizing tube 23. Furthermore, along the circumference of the atomizing tube 23, multiple perforated portions 230 can be provided within the length range corresponding to a heating element 221, allowing the aerosol matrix to flow from different directions to the same heating element 221, thereby improving the efficiency of heating and atomizing the aerosol matrix by the heating element 221. This application does not impose any special limitations on the specific shape of the perforated portion 230 on the atomizing tube 23. Additionally, the material of the atomizing tube 23 can be a fiberglass tube; this application does not impose any special limitations on the specific material of the atomizing tube 23.

[0052] In some embodiments, such as Figure 4 and Figure 5As shown, the liquid guiding assembly 21 may include multiple liquid guiding elements with different adsorption forces; the multiple liquid guiding elements are arranged along the extension direction of the atomizing tube 23, and two adjacent liquid guiding elements are in contact with each other. Along the direction of gravity, the adsorption force of the upper liquid guiding element on the aerosol matrix is ​​greater than that of the lower liquid guiding element on the aerosol matrix, so as to counteract at least part of the gravity of the aerosol matrix adsorbed by the upper liquid guiding element.

[0053] For example, the liquid guiding assembly 21 may include a first liquid guiding element 211 and a second liquid guiding element 212. The first liquid guiding element 211 is disposed below the second liquid guiding element 212 along the direction of gravity (the downward direction shown by the arrow in the figure), and the second liquid guiding element 212 is in contact with the first liquid guiding element 211. The adsorption force of the second liquid guiding element 212 on the aerosol matrix is ​​greater than the adsorption force of the first liquid guiding element 211 on the aerosol matrix, thereby counteracting at least a portion of the gravity of the aerosol matrix adsorbed by the second liquid guiding element 212. Therefore, when the liquid guiding component 21 adsorbs the aerosol matrix, the second liquid guiding component 212, located at a higher position, can counteract at least part of the gravity of the aerosol matrix within the second liquid guiding component 212 through stronger adsorption force. This slows down the rate at which the aerosol matrix within the second liquid guiding component 212 flows towards the first liquid guiding component 211, so that the aerosol matrix within the first liquid guiding component 211 and the second liquid guiding component 212 is as evenly distributed as possible. This reduces the problem of insufficient local liquid supply caused by the aerosol matrix within the second liquid guiding component 212 flowing towards the first liquid guiding component 211 under the action of gravity.

[0054] Furthermore, the perforated portion 230 on the wall of the atomizing tube 23 allows for a more even flow of the aerosol matrix from the liquid guiding component 21 to the heating component 22. For example, the opening area of ​​the perforated portion 230 near the second liquid guiding component 212 can be set to be larger than the opening area of ​​the perforated portion 230 near the first liquid guiding component 211. This means the opening area of ​​the perforated portion 230 on the wall of the atomizing tube 23 gradually decreases from top to bottom. This makes the liquid supply rate of the first liquid guiding component 211 to the lower heating component 221 more consistent with the liquid supply rate of the second liquid guiding component 212 to the upper heating component 221, thus ensuring the stability of the heating component 22 during atomization. This application does not impose any special limitations on the opening area of ​​the perforated portion 230 on the wall of the atomizing tube 23.

[0055] It should be noted that the number of liquid guiding elements in the liquid guiding assembly 21 is not limited to the first liquid guiding element 211 and the second liquid guiding element 212. For example, the liquid guiding assembly 21 may also include a third liquid guiding element, a fourth liquid guiding element, or more liquid guiding elements, with different liquid guiding elements having different adsorption forces. Along the direction of gravity, liquid guiding elements with greater adsorption forces are placed at higher positions, and liquid guiding elements with less adsorption forces are placed at lower positions. When the liquid guiding assembly 21 adsorbs the aerosol matrix, the aerosol matrix can continuously rise from the liquid guiding element with less adsorption force to the liquid guiding element with greater adsorption force within the liquid guiding assembly 21, so that the aerosol matrix is ​​more evenly distributed within the liquid guiding assembly 21, avoiding the problem of insufficient local liquid supply in the liquid guiding assembly 21. This application does not impose any special limitation on the specific number of liquid guiding elements in the liquid guiding assembly 21.

[0056] It is understood that the liquid guiding component 21 provided in this application is not limited to use in liquid storage components 1 with a liquid storage chamber 15 and a liquid passage chamber 16, but is also applicable to liquid storage components 1 with independent liquid storage chambers. When the liquid guiding component 21 adsorbs the aerosol matrix, the second liquid guiding element 212, located at a higher position, can counteract at least part of the gravity of the aerosol matrix within the second liquid guiding element 212 through stronger adsorption force, thus keeping the aerosol matrix within the liquid guiding component 21 in a state of vertical equilibrium. However, the flow of the aerosol matrix from the second liquid guiding element 212 into the first liquid guiding element 211 depends not only on the gravity of the aerosol matrix, but also on the adsorption force of the first liquid guiding element 211. For example, when the aerosol matrix in the first liquid guiding element 211 is consumed, the aerosol matrix in the second liquid guiding element 212 can still flow to the first liquid guiding element 211 under the adsorption force of the first liquid guiding element 211, thereby maintaining the aerosol matrix within the liquid guiding component 21 in a state of vertical equilibrium.

[0057] To achieve different adsorption capacities for different liquid guiding components, such as... Figures 6 to 8 As shown, the lower liquid guiding element (e.g., the first liquid guiding element 211) has a plurality of first capillary pores 213, and the upper liquid guiding element (e.g., the second liquid guiding element 212) has a plurality of second capillary pores 214; the density of the second capillary pores 214 may be greater than the density of the first capillary pores 213; and / or, the pore diameter of the second capillary pores 214 may be smaller than the pore diameter of the first capillary pores 213.

[0058] For example, such as Figure 6As shown, the pore size of the first capillary 213 in the first liquid guiding component 211 can be the same as the pore size of the second capillary 214 in the second liquid guiding component 212. However, the density of the second capillary 214 in the second liquid guiding component 212 is greater than the density of the first capillary 213 in the first liquid guiding component 211. This makes the porosity of the second liquid guiding component 212 greater than that of the first liquid guiding component 211. As a result, the second liquid guiding component 212 can adsorb a larger amount of aerosol matrix more quickly than the first liquid guiding component 211, thereby increasing the adsorption force of the second liquid guiding component 212.

[0059] For example, such as Figure 7 As shown, the density of the first capillary pore 213 in the first liquid guiding element 211 can be the same as the density of the second capillary pore 214 in the second liquid guiding element 212, but the pore diameter of the second capillary pore 214 is smaller than that of the first capillary pore 213. According to the capillary principle, the smaller the pore diameter of the capillary, the greater the adsorption force generated by the capillary under the action of liquid tension, which can draw the liquid into the capillary more quickly and effectively, thus making the adsorption force of the second liquid guiding element 212 greater than that of the first liquid guiding element 211.

[0060] For example, such as Figure 8 As shown, the density of the second capillary pores 214 in the second liquid guiding element 212 is greater than the density of the first capillary pores 213 in the first liquid guiding element 211, and the pore diameter of the second capillary pores 214 is smaller than the pore diameter of the first capillary pores 213. In this way, a large number of capillaries have smaller pore diameters, allowing the adsorption forces of the capillaries to be superimposed and work together to increase the total adsorption force of the second liquid guiding element 212, thereby improving the adsorption force of the second liquid guiding element 212.

[0061] In other embodiments, the material of the upper liquid guiding element (e.g., the second liquid guiding element 212) can be nonwoven fabric, porous ceramic, fiber, sponge or water-absorbing polymer, and the material of the lower liquid guiding element (e.g., the first liquid guiding element 211) can be nonwoven fabric, porous ceramic, fiber, sponge or water-absorbing polymer; wherein, the adsorption force of the material of the upper liquid guiding element is greater than that of the material of the lower liquid guiding element.

[0062] For example, the first liquid guiding component 211 can be made of a non-woven fabric material with absorbent properties, and the second liquid guiding component 212 can be made of a water-absorbing polymer material with stronger absorbent properties than the first liquid guiding component 211, thereby making the absorbent properties of the second liquid guiding component 212 greater than those of the first liquid guiding component 211. The materials of the first liquid guiding component 211 and the second liquid guiding component 212 include, but are not limited to, polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), polyurethane (PA), etc. This application does not impose any special restrictions on the specific materials of the first liquid guiding component 211 and the second liquid guiding component 212.

[0063] Furthermore, the materials of the first liquid guiding element 211 and the second liquid guiding element 212 can be combined with the capillary density and / or pore size of the first liquid guiding element 211 and the second liquid guiding element 212 to increase the adsorption force of the second liquid guiding element 212. For example, the first liquid guiding element 211 is made of non-woven fabric, and the second liquid guiding element 212 is made of a water-absorbing polymer material with stronger adsorption force than the first liquid guiding element 211. At the same time, the density of the second capillary pores 214 in the second liquid guiding element 212 is greater than the density of the first capillary pores 213 in the first liquid guiding element 211. As another example, the first liquid guiding element 211 is made of non-woven fabric, and the second liquid guiding element 212 is made of a water-absorbing polymer material with stronger adsorption force than the first liquid guiding element 211. At the same time, the pore size of the second capillary pores 214 in the second liquid guiding element 212 is smaller than the pore size of the first capillary pores 213 in the first liquid guiding element 211. For example, the first liquid guiding component 211 is made of non-woven fabric, and the second liquid guiding component 212 is made of a water-absorbing polymer material with stronger adsorption force than the first liquid guiding component 211. At the same time, the density of the second capillary 214 in the second liquid guiding component 212 is greater than the density of the first capillary 213 in the first liquid guiding component 211, and the pore size of the second capillary 214 is smaller than the pore size of the first capillary 213.

[0064] In some embodiments, such as Figure 9 As shown, the heating power of the multiple heating elements 221 arranged at intervals along the direction of gravity can gradually increase.

[0065] For example, the multiple heating elements 221 may include a first heating element 2211, a second heating element 2212, and a third heating element 2213 arranged from bottom to top. The heating power of the first heating element 2211 can be set to 12 watts, the heating power of the second heating element 2212 can be set to 11 watts, and the heating power of the third heating element 2213 can be set to 10 watts. During atomization, the aerosol matrix is ​​affected by gravity; the higher-positioned liquid guide element adsorbs less aerosol matrix than the lower-positioned liquid guide element. By setting the multiple heating elements 221 to different heating powers, the heating element 221 with lower heating power can be matched with the higher-positioned liquid guide element for heating and atomization, and the heating element 221 with higher heating power can be matched with the lower-positioned liquid guide element for heating and atomization, thereby avoiding the dry-burning problem caused by insufficient local liquid supply to the liquid guide assembly 21. In other embodiments, the multiple heating elements 221 may also be set to the same heating power. This application does not impose any special limitations on the specific heating power of the multiple heating elements 221 within the atomizing core 2.

[0066] Among them, such as Figure 4As shown, along the direction of gravity, the hollow portions 230 of each layer on the wall of the atomizing tube 23 can each face a heating element 221. During atomization, the aerosol matrix adsorbed by the liquid guiding component 21 can flow directly to the heating element 221 for heating and atomization along the direction indicated by the hollow arrow in the figure, thereby shortening the flow path of the aerosol matrix and improving the atomization efficiency of the aerosol matrix. This application does not impose any special restrictions on the specific location of the hollow portions 230 on the wall of the atomizing tube 23.

[0067] In addition, such as Figure 9 As shown, the power supply component 3 may include a first electrode (not shown) and a plurality of second electrodes (not shown); each heating element 221 has two pins, one of which is electrically connected to the first electrode, and the other pin of each heating element 221 is electrically connected to a plurality of second electrodes respectively.

[0068] For example, the power supply component 3 may include a first electrode and three second electrodes. When the multiple heating elements 221 include a first heating element 2211, a second heating element 2212, and a third heating element 2213, one pin of each heating element 221 can be soldered to form a pin and electrically connected to the first electrode, while the other pin of each heating element 221 is electrically connected to the three second electrodes respectively, thereby reducing the number of electrodes on the power supply component 3 used to connect the heating elements 221. In other embodiments, the power supply component 3 may also include three first electrodes and three second electrodes. This application does not impose any special limitation on the number of electrodes provided on the power supply component 3.

[0069] In some embodiments, such as Figure 4 and Figure 5 As shown, the heating element 22 may also include a liquid guide 222; the adsorption force of the liquid guide 222 on the aerosol matrix is ​​greater than or equal to the adsorption force of the liquid guide component 21 on the aerosol matrix, the liquid guide 222 is disposed between the heating element 221 and the tube wall along the extension direction of the atomizing tube 23, the liquid guide 222 contacts the liquid guide component 21 through the hollow part 230, and multiple heating elements 221 are in contact with the liquid guide 222.

[0070] The adsorption force of the liquid guide 222 on the aerosol matrix is ​​set to be greater than or equal to the adsorption force of the liquid guide assembly 21 on the aerosol matrix. This allows the liquid guide 222 to quickly provide the aerosol matrix adsorbed by the liquid guide assembly 21 to the heating element 221 for heating and atomization, thus avoiding problems such as dry burning of the liquid guide 222 or leakage of the aerosol matrix from the liquid guide assembly 21 due to poor liquid guide performance. Furthermore, by placing the liquid guide 222 between the heating element 221 and the liquid guide assembly 21, the high temperature of the heating element 221 during operation can be isolated by the liquid guide 222, thereby reducing the high-temperature damage to the liquid guide assembly 21 during the operation of the heating element 221 and extending the lifespan of the liquid guide assembly 21 during the use of the atomizing core 2. The heating element 221 can be a metal heating mesh or a metal heating wire structure, and the liquid guide 222 can be made of materials such as non-woven fabric, porous ceramic, fiber, sponge, or absorbent polymer. This application does not impose any special restrictions on the specific materials of the heating element 221 and the liquid guide 222.

[0071] It is understandable that by making the liquid guide 222 an integral structure along the extension direction of the atomizing tube 23, when assembling the atomizing core 2, multiple heating elements 221 can be installed inside the liquid guide 222 first to fix the relative positions between the multiple heating elements 221, and then the entire heating assembly 22 can be installed inside the atomizing tube 23, thereby reducing the difficulty of assembling the atomizing core 2. In other embodiments, the liquid guide 222 can also be configured as a segmented structure, so that one heating element 221 is installed inside one liquid guide 222. This application does not impose any special limitations on the specific structure of the liquid guide 222.

[0072] In some embodiments, such as Figure 4 and Figure 5 As shown, the atomizing core 2 may also include an atomizing cover 24; the side wall of the atomizing cover 24 is provided with a plurality of liquid passage holes 240, the plurality of liquid passage holes 240 are provided on the outer periphery of the liquid guiding component 21, the atomizing cover 24 and the atomizing tube 23 surround to form a receiving cavity 25, the liquid guiding component 21 is disposed in the receiving cavity 25, and the inner surface of the liquid guiding component 21 is in contact with the outer wall of the atomizing tube 23, and the outer surface of the liquid guiding component 21 is in contact with the inner wall of the atomizing cover 24.

[0073] When the aerosol matrix flows into the liquid passage chamber 16, the aerosol matrix in the liquid passage chamber 16 can flow into the atomizing core 2 from different directions through multiple liquid passage holes 240 for heating and atomization, thereby avoiding the dry burning problem caused by insufficient local liquid supply to the liquid guiding component 21. The liquid passage holes 240 can also be located at the bottom of the liquid passage chamber 16, allowing all the aerosol matrix in the liquid passage chamber 16 to flow into the atomizing core 2 through the liquid passage holes 240, thus improving the utilization rate of the aerosol matrix. The receiving cavity 25 formed between the atomizing cover 24 and the atomizing tube 23 allows the liquid guiding component 21 to be clamped between the atomizing cover 24 and the atomizing tube 23 after being installed in the receiving cavity 25, thereby ensuring the relatively fixed position of the liquid guiding component 21.

[0074] In addition, such as Figure 3 As shown, the atomizing device may further include a lower seal 26 and an upper seal 27. The axial length of the atomizing cover 24 may be greater than the length of the liquid guiding assembly 21, that is, the top of the atomizing cover 24 may be higher than the top of the second liquid guiding member 212, and the bottom of the atomizing cover 24 may be lower than the bottom of the first liquid guiding member 211. This allows the top of the atomizing cover 24 to accommodate the upper seal 27 to seal the top of the atomizing core 2, and the bottom of the atomizing cover 24 to accommodate the lower seal 26 to seal the bottom of the atomizing core 2. The atomizing cover 24 may be made of plastic, and this application does not impose any special restrictions on the specific structure and material of the atomizing cover 24.

[0075] In this application, the liquid storage chamber 15 can be considered as the first liquid storage mechanism, the liquid passage chamber 16 as the second liquid storage mechanism, the liquid guiding component 21 as the third liquid storage mechanism, and the liquid guiding component 222 as the fourth liquid storage mechanism. This allows the aerosol matrix within the atomizing device to be supplied to the heating element 221 in stages for heating and atomization. When the aerosol matrix in the liquid storage chamber 15 is insufficient, the liquid passage chamber 16, the liquid guiding component 21, and the liquid guiding component 222 can continue to supply liquid to the heating element 221. Similarly, when the aerosol matrix in the liquid passage chamber 16 is insufficient, the liquid guiding component 21 and the liquid guiding component 222 can continue to supply liquid to the heating element 221. Furthermore, when the aerosol matrix in the liquid guiding component 21 is insufficient, the liquid guiding component 222 can continue to supply liquid to the heating element 221. This avoids the problem of dry burning caused by insufficient localized liquid supply to the atomizing device.

[0076] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
