Description

Technical Field

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

[0002] Currently, some atomizing devices include an atomizer and a power supply component. The atomizer's atomizing core component, when powered on or receiving power, generates heat to heat the atomizing matrix, producing an inhalable aerosol for the user. The atomizing core component includes a single layer of reservoir cotton arranged along the height direction to guide the atomizing matrix. This arrangement has several problems. For example, it occupies space in the height direction, making it impossible to achieve a compact assembly of the atomizing core component and the power supply component within the same height space. Additional height space must be reserved to arrange the two types of components sequentially, resulting in wasted space. At the same time, the structural limitations of the single-layer reservoir cotton restrict the length of the reservoir, making the visible liquid level height the first consideration, affecting the user experience.

[0009] In some alternative embodiments, the first liquid reservoir and the second liquid reservoir are made of the same material, and the density of the first liquid reservoir is less than the density of the second liquid reservoir.

[0010] In some alternative embodiments, in a direction perpendicular to the height, the orthographic projection of the first liquid reservoir onto the heating element covers a portion of the heating element; and / or, in a direction perpendicular to the height, the orthographic projection of the first liquid reservoir onto the heating element completely covers the heating element.

[0011] In some optional embodiments, the overlapping area accounts for no less than 1 / 3 of the height of the first liquid storage component; and / or, in the direction perpendicular to the height, the projected area of ​​the overlapping area is no less than 1 / 3 of the projected area of ​​the corresponding part of the first liquid storage component that overlaps with the second liquid storage component.

[0012] In some optional embodiments, the first receiving cavity includes a first cavity, a second cavity, and a third cavity arranged sequentially from bottom to top along the height direction. The second cavity connects the first cavity and the third cavity. The outer diameter of the first cavity is larger than the outer diameter of the third cavity. The first liquid storage element is disposed in the first cavity and its top end extends into the second cavity. The top end of the second liquid storage element is disposed in the third cavity, and its bottom end extends into the second cavity and overlaps with the first liquid storage element.

[0013] In some optional embodiments, the support assembly includes an outer tube, an inner tube, and a base, wherein the second receiving cavity is formed inside the inner tube; the third receiving cavity is formed inside the base; the inner tube is disposed inside the outer tube, the base is inserted into the outer tube and its top end is connected to the bottom end of the inner tube, and the bottom end of the outer tube is connected to the base, so as to enclose and form the first receiving cavity.

[0014] In some alternative embodiments, the support assembly further includes a first seal and a second seal, the first seal being disposed at the bottom end of the inner tube; the second seal being disposed between the base and the outer tube, and its top end abutting against the bottom end of the first seal.

[0015] In some optional embodiments, the base is provided with a first limiting structure, and the second sealing member is provided with a second limiting structure. The first limiting structure and the second limiting structure are correspondingly arranged and are plugged into each other.

[0016] In some optional embodiments, the outer tube is provided with a first liquid inlet channel, which connects the first receiving cavity and the outside of the atomizing core assembly; the inner tube is provided with a second liquid inlet channel, which connects the first receiving cavity and the second receiving cavity.

[0017] According to a second aspect, embodiments of this application provide an atomizer, including a liquid storage chamber and an atomizing core assembly as described above, wherein the atomizing core assembly is disposed within the liquid storage chamber and surrounds it to form a liquid storage cavity, the liquid storage cavity being used to store an atomizing matrix.

[0018] In some alternative embodiments, a third seal is provided between the liquid reservoir and the top of the atomizing core assembly.

[0019] According to a third aspect, embodiments of this application provide an atomizing device, including a power supply component and the aforementioned atomizer, wherein at least a portion of the power supply component is inserted into the third receiving cavity for supplying power to the atomizer.

The double-layer design of the liquid storage element can slowly guide the liquid so that the heating element can atomize the atomizing matrix. Furthermore, the adsorption effect of the double-layer liquid storage element will not cause a large amount of flowing atomizing matrix to flow to the lead assembly between the heating elements, thus solving the technical problem of easy leakage of single-layer liquid storage elements and improving the safety of the atomizing device.

[0022] According to the atomizer in this embodiment, including the above-mentioned atomizing core assembly, since the first liquid storage element and the second liquid storage element are arranged along the height direction, the dimension of the atomizing core assembly in the height direction can be extended, thereby increasing the visible height of the liquid storage chamber.

[0023] The atomizing device according to this embodiment includes the atomizer and power supply component described above. Due to the height difference arrangement of the two liquid storage components, the atomizing core component and the power supply component can be installed separately within the height space they occupy. This breaks through the limitation of a single liquid storage component occupying only axial space, and there is no need to reserve additional assembly space. This achieves a compact layout of the atomizer and power supply component in the atomizing device, and improves the occupancy rate of the internal space of the atomizing device.

[0034] Y, the height direction. Detailed Implementation

[0035] The present application will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. 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.

[0036] 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.

[0037] 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).

[0038] This application provides an atomizing device whose atomizing core assembly includes two liquid storage components arranged from the outside to the inside, forming a liquid storage assembly. The two liquid storage components have a height difference in the vertical direction, with the outer first liquid storage component positioned lower than the inner second liquid storage component. There is an overlapping area between the first and second liquid storage components to establish a liquid flow path between them, facilitating the guidance of the atomizing matrix from the first liquid storage component to the second liquid storage component and ensuring a smooth liquid flow path between the components. Because the first and second liquid storage components are arranged along the vertical direction, the dimension of the atomizing core assembly in the vertical direction can be extended, thereby increasing the visible height of the liquid storage chamber. Due to the layered arrangement of the two liquid storage components, the atomizing core assembly and the power supply assembly can be installed separately within their respective height spaces, overcoming the limitation of a single-layer liquid storage component occupying only axial space. No additional assembly space is required, thus achieving a compact layout of the atomizer and the power supply assembly, improving the internal space utilization rate of the atomizing device. Meanwhile, the double-layer liquid storage device can slowly guide the liquid to enable the heating element to atomize the atomizing matrix. Furthermore, the adsorption effect of the double-layer liquid storage device prevents a large amount of flowing atomizing matrix from flowing to the lead assembly between the heating elements, thus solving the technical problem of easy leakage of single-layer liquid storage devices and improving the safety of the atomizing device.

[0039] In this application, the term "aerosol" is generally used to refer to a substance that has been vaporized, atomized, sprayed or jetted, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0040] In this application, the term "atomizing matrix" refers to any suitable compound or mixture of compounds that facilitates the formation of an aerosol (e.g., a stable aerosol that is substantially resistant to thermal degradation at the system's operating temperature) during use. Suitable atomizing matrices are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono-, di-, or triacetic acid esters of glycerol; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecanoate. Aerosol-generating articles may include nicotine. Aerosol-generating articles may include water. Atomizing matrices may include glycerol (also known as glycerol) having a higher boiling point than nicotine. Atomizing matrices may include propylene glycol. Atomizing matrices may include plant-based materials. Atomizing matrices may include homogeneous plant substrates. Homogeneous plant substrates may contain volatile compounds. These compounds may be released from the atomizing matrix upon heating.

[0041] Please see Figures 1 to 8 The atomizing device includes an atomizer 1 and a power supply component 2.

[0042] For ease of description, following the usage habits of atomizing devices, a height direction Y is defined. The atomizer 1 and power supply component 2 can be arranged sequentially along the height direction Y. The user can inhale from the top of the atomizing device (the uppermost part of the height direction Y), and the generated aerosol is discharged from the top of the atomizing device from bottom to top. For example... Figure 1 As shown, the direction parallel to the Y-axis is the height direction Y, as... Figure 3 As shown, the arrows indicate the direction of aerosol flow.

[0043] The atomizer 1 includes a liquid storage chamber 11 and an atomizing core assembly 12. The atomizing core assembly 12 is disposed within the liquid storage chamber 11 and encloses it to form a liquid storage cavity 13, which is used to store the atomizing substrate. The atomizing core assembly 12 can communicate with the liquid storage cavity 13 to guide the atomizing substrate in the liquid storage cavity 13 to the atomizing core assembly 12. When energized or receiving electricity, the atomizing core assembly 12 can heat the atomizing substrate to generate an aerosol.

[0044] Please see Figure 3 The atomizing core assembly 12 includes a support assembly 121, a liquid storage assembly 122, and a heating assembly 123.

[0045] The support assembly 121 can be understood as a collection of multiple components. The support assembly 121 provides space for the installation of the liquid storage assembly 122 and the heating assembly 123. Simultaneously, the structural design of the support assembly 121 also provides at least partial installation space for the power supply assembly 2. Please refer to... Figure 4 The bracket assembly 121 has independently arranged first receiving cavity 1216, second receiving cavity 1217 and third receiving cavity 1218; the second receiving cavity 1217 and the third receiving cavity 1218 are both arranged inside the first receiving cavity 1216 and are isolated from each other along the height direction Y; the third receiving cavity 1218 is used to accommodate at least part of the structure of the power supply assembly 2.

[0046] Please continue reading. Figure 4 A liquid storage assembly 122 is disposed within a first receiving cavity 1216. The liquid storage assembly 122 includes a first liquid storage element 1221 and a second liquid storage element 1222, which are arranged sequentially from bottom to top along the height direction Y. The first liquid storage element 1221 and the second liquid storage element 1222 have an overlapping area to guide the atomized matrix from bottom to top from the first liquid storage element 1221 to the second liquid storage element 1222. A heating element 123 is disposed within a second receiving cavity 1217 and is in contact with the second liquid storage element 1222. The heating element 123 is used to heat the atomized matrix from the second liquid storage element 1222 to generate an aerosol.

[0047] In some embodiments, the heating assembly 123 includes a liquid guiding member 1231 and a heating element 1232. The liquid guiding member 1231 is in contact with the second liquid storage member 1222, and the heating element 1232 is disposed in conform to the inner wall of the liquid guiding member 1231 to store and guide the atomized matrix through the liquid guiding member 1231 to the heating element 1232. The heating element 1232 may include a perforated tubular structure, a heating mesh, or a heating wire (spiral).

[0048] In some embodiments, the capillary driving force of the second liquid storage device 1222 is greater than that of the first liquid storage device 1221, thereby enabling the atomizing matrix in the first liquid storage device 1221 to be directed to the second liquid storage device 1222 according to the difference in capillary driving force, thus achieving the replenishment of the atomizing matrix; and the second liquid storage device 1222 can continuously and stably deliver the atomizing matrix to the heating component 123 with its stronger capillary driving force, thereby meeting the atomization liquid supply requirements of the heating component 123.

[0049] In this application, the term "capillary driving force" refers to the spontaneous liquid-phase mass transfer force generated by the solid-liquid surface tension difference in the capillary channels formed within the internal gaps of the liquid reservoir, which is the driving force for the liquid absorption and conduction of the reservoir. The capillary driving force is related to the hydrophilicity of the liquid reservoir itself (determined by the manufacturing material) and its porosity (related to density, etc.). The stronger the hydrophilicity of the liquid reservoir, the stronger its capillary driving force. The greater the density and the smaller the porosity of the liquid reservoir, the stronger its capillary driving force.

[0050] In this application, the term "density" refers to the mass per unit volume of the liquid storage component.

[0051] In this application, the term "porosity" refers to the percentage of pore volume within a liquid reservoir to its total apparent volume. The density and porosity of a liquid reservoir are negatively correlated; that is, the higher the density, the lower the porosity.

[0052] The first liquid storage component 1221 and the second liquid storage component 1222 can be porous structures made of ceramic or fibrous materials. Fiber materials include plant fibers such as cotton and wood fibers, and may also include synthetic polymer fibers. A porous structure is a part with multiple channels that can form a liquid flow path for the atomizing matrix to pass through.

[0053] In some embodiments, the first liquid storage element 1221 and the second liquid storage element 1222 are made of the same material, and the density of the first liquid storage element 1221 is less than the density of the second liquid storage element 1222. Since the same material has the same hydrophilic properties for liquids, the higher the density and the lower the internal porosity of the liquid storage element of the same material, the stronger the capillary driving force. Thus, the difference in density between the two can achieve a capillary driving force difference design, effectively ensuring that the atomizing matrix is ​​directionally transported between the first liquid storage element 1221 and the second liquid storage element 1222 under the action of the capillary driving force difference. For example, the first liquid storage component 1221 and the second liquid storage component 1222 can be liquid storage cotton made of cotton fibers. The density of the first liquid storage component 1221 is less than that of the second liquid storage component 1222. It has more pores, and the strong hydrophilicity of cotton fibers combined with high porosity can firmly lock the atomizing matrix and store more atomizing matrix through capillary adsorption. The second liquid storage component 1222 has a higher density and stronger capillary liquid locking ability, which can prevent leakage problems caused by excessively wide liquid guiding channels or insufficient liquid locking. It can also slowly transfer the atomizing matrix to the heating element 123, ensuring that the supply of atomizing matrix at the heating element 123 matches the atomization rate. This avoids liquid accumulation and leakage caused by excessively fast liquid guiding, and also avoids dry burning problems caused by delayed liquid guiding.

[0054] Of course, in other embodiments, the first liquid storage element 1221 and the second liquid storage element 1222 are made of different materials. For example, the first liquid storage element 1221 is made of ceramic material, and the second liquid storage element 1222 is made of cotton fiber or synthetic composite fiber. Porous ceramic material itself has weak hydrophilicity, and the capillary driving force is only provided by the pores, resulting in weak driving force. Ceramic is a rigid structure, which can provide support for the second liquid storage element 1222, adapting to the extended design of the liquid storage cavity 13. Cotton fiber or composite fiber has much better hydrophilicity than ceramic, and the fiber has strong capillary driving force. When arranged in close contact with the heating element 123, it can achieve high-speed liquid conduction.

[0055] In some embodiments, in the direction perpendicular to the height Y, the orthographic projection of the first liquid storage component 1221 onto the heating component 123 covers a portion of the heating component 123 to reduce the liquid flow path and ensure smooth atomization of the matrix; and / or, in the direction perpendicular to the height Y, the orthographic projection of the first liquid storage component 1221 onto the heating component 123 completely covers the heating component 123 to increase the contact area and improve the liquid conduction efficiency.

[0056] In some embodiments, the overlapping area accounts for no less than 1 / 3 of the height of the first liquid storage component 1221; and / or, in the direction perpendicular to the height Y, the projected area of ​​the overlapping area is no less than 1 / 3 of the projected area of ​​the corresponding part of the first liquid storage component 1221 that overlaps with the second liquid storage component 1222, so as to further ensure the contact area.

[0057] It should be noted that, in this application, the term "overlapping corresponding part" refers to the area on the first liquid storage component 1221 that has spatial overlap with the second liquid storage component 1222 in the height direction Y, that is, the part of the first liquid storage component 1221 that can form contact or be arranged opposite to the second liquid storage component 1222, and its range is based on the projection coverage of the first liquid storage component 1221 on the second liquid storage component 1222.

[0058] In this application, the term "overlapping area" refers to the area where the first liquid reservoir 1221 and the second liquid reservoir 1222 actually overlap in space. For example, both the first liquid reservoir 1221 and the second liquid reservoir 1222 are hollow tubular structures, with the outer diameter of the first liquid reservoir 1221 being larger than that of the second liquid reservoir 1222. The first liquid reservoir 1221 is fitted over the second liquid reservoir 1222, and the portion of the two that overlaps is the overlapping area. When the second liquid reservoir 1222 does not completely cover the corresponding overlapping portion of the first liquid reservoir 1221, the overlapping area is the portion where the two actually overlap, and its range is less than or equal to the range of the corresponding overlapping portion. For example, the overlapping positions of the first liquid storage component 1221 and the second liquid storage component 1222 are not continuous structures, but rather multiple contact parts arranged at intervals. These multiple contact parts are evenly distributed around the central axis of the first liquid storage component 1221. Due to the intervals between them, the sum of the areas of the multiple contact parts is less than the area calculated based on the outer diameter of the first liquid storage component 1221, that is, less than the range of the corresponding overlapping parts.

[0059] Please see Figure 5 In some embodiments, the first receiving cavity 1216 includes a first cavity 1216a, a second cavity 1216b, and a third cavity 1216c arranged sequentially from bottom to top along the height direction Y. The second cavity 1216b connects the first cavity 1216a and the third cavity 1216c. The outer diameter of the first cavity 1216a is larger than the outer diameter of the third cavity 1216c. The first liquid storage member 1221 is disposed in the first cavity 1216a, and its top end extends into the second cavity 1216b. The top end of the second liquid storage member 1222 is disposed in the third cavity 1216c, and its bottom end extends into the second cavity 1216b and overlaps with the first liquid storage member 1221. The sum of the width of the first cavity 1216a (i.e., the maximum lateral dimension in the direction Y perpendicular to the height of the atomizing device, the same below) and the width of the third cavity 1216c is the width of the second cavity 1216b, so that the first receiving cavity 1216 has no redundant space wasted in the direction Y perpendicular to the height, which helps to achieve a compact layout in the atomizing device.

[0060] Please continue reading. Figure 5 The support assembly 121 includes an outer tube 1211, an inner tube 1212, and a base 1213. A second receiving cavity 1217 is formed inside the inner tube 1212; a third receiving cavity 1218 is formed inside the base 1213. The inner tube 1212 is disposed inside the outer tube 1211, and the base 1213 is inserted into the outer tube 1211, with its top end connected to the bottom end of the inner tube 1212. The bottom end of the outer tube 1211 is connected to the base 1213 to enclose and form a first receiving cavity 1216.

[0061] The shape of the inner tube 1212 is not limited; it can be cylindrical, prismatic, or square. The outer tube 1211 consists of two parts with different outer diameters: a first part at the top and a second part at the bottom. The outer diameter of the first part is smaller than that of the second part. The first part and the inner tube 1212 cooperate to form a third cavity 1216c. The length of the inner tube 1212 is less than the length of the outer tube 1211 but greater than the length of the first part. The inner tube 1212 extends from the first part into the second part, thereby cooperating with the second part to form a first cavity 1216a and a second cavity 1216b. The shapes of the first and second parts of the outer tube 1211 are also not limited; they can be cylindrical, prismatic, or square.

[0062] The base 1213 includes a portion that inserts into the outer tube 1211 and a portion that connects to the end of the outer tube 1211. These two portions can be constructed in a "U" shape, which can make full use of the space inside the outer tube 1211 without increasing the volume in the height direction Y.

[0063] Please continue reading. Figure 4 and Figure 5 The support assembly 121 also includes a first seal 1214 and a second seal 1215. The first seal 1214 is disposed at the bottom end of the inner tube 1212; the second seal 1215 is disposed between the base 1213 and the outer tube 1211, and its top end abuts against the bottom end of the first seal 1214. The arrangement of the first seal 1214 and the second seal 1215 helps to seal the first receiving cavity 1216, preventing the atomized matrix from leaking or seeping through the assembly gap between the outer tube 1211, the inner tube 1212, and the base 1213.

[0064] The first seal 1214 and the second seal 1215 are provided with a through hole extending along the height direction Y in the middle. The through hole 1219 can connect the heating element 123 and the bottom of the atomizing device. When the user inhales, the air entering from the bottom air inlet 211 can flow into the heating element 123 and carry the aerosol out from the top of the atomizing device.

[0065] In some embodiments, the base 1213 is provided with a first limiting structure 1213a, and the second sealing member 1215 is provided with a second limiting structure 1215a. The first limiting structure 1213a and the second limiting structure 1215a are correspondingly arranged and are plugged into each other. One of the first limiting structure 1213a and the second limiting structure 1215a is a limiting protrusion, and the other is a limiting groove. The limiting protrusion is plugged into the limiting groove to achieve a stable connection between the base 1213 and the second sealing member 1215, thereby ensuring the stability of the overall structure of the atomizing device and the sealing effect. Please refer to [link / reference]. Figure 4The first limiting structure 1213a is a limiting groove, and two are symmetrically arranged along its own center line. The second limiting structure 1215a is a limiting protrusion, and the number and position of the limiting protrusions correspond to the limiting grooves. During the assembly of the atomizing device, the limiting protrusions are inserted into the limiting grooves. Of course, this application does not limit the shape and number of the first limiting structure 1213a and the second limiting structure 1215a. To further ensure the stability of the connection, the first limiting structure 1213a and the second limiting structure 1215a can each have three or more. The limiting protrusions in the first limiting structure 1213a and the second limiting structure 1215a can be cylindrical, square, or prismatic, and the limiting grooves are of a matching shape.

[0066] Please see Figure 4 , Figure 5 and Figure 6 In some embodiments, the outer tube 1211 is provided with a first liquid inlet channel 1211a, which connects the first receiving cavity 1216 with the outside of the atomizing core assembly 12, i.e., the first receiving cavity 1216 is connected with the liquid storage cavity 13. The inner tube 1212 is provided with a second liquid inlet channel 1212a, which connects the first receiving cavity 1216 with the second receiving cavity 1217. It can be understood that the first liquid inlet channel 1211a, the first liquid storage component 1221, the second liquid storage component 1222, and the second liquid inlet channel 1212a constitute a liquid flow path.
