Atomizing assembly and atomizer

Abstract

The application provides an atomization assembly and an atomizer, and relates to the technical field of electronic atomization. The atomization assembly is internally formed with an atomization channel. The atomization channel comprises a first part, a second part and a third part. The first part and the third part are respectively arranged at two ends of the second part. The inner diameter of the first part and the third part is greater than the inner diameter of the second part. Due to the fact that the inner diameter of the first part and the third part of the atomization channel is greater than the inner diameter of the second part, the atomization channel is formed in a big-in-the-two-ends-and-small-in-the-middle shape. Based on the Venturi effect, when the atomization assembly is working or a user is inhaling, the gas flow rate in the second part reaches a maximum value, and the static pressure reaches a minimum value. As a result, a pressure difference is formed between the inside and the outside of the second part. Based on the pressure difference, the atomization assembly has a greater adsorption force on the atomization substrate, so that the atomization substrate is more quickly introduced, thereby ensuring the sufficiency of the atomization substrate and avoiding the occurrence of the paste core phenomenon. Meanwhile, a series of problems caused by the paste core are solved.

Description

Technical Field

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

[0002] Atomizers utilize their electronic atomization components to heat and atomize an atomizing matrix to form an aerosol, which is then used by the user for inhalation. Related technologies employ a heating element encased in a liquid-conducting component. While this combination achieves a degree of integration of heating and auxiliary functions, it suffers from problems such as insufficient liquid supply and wicking issues during actual use.

[0003] The liquid guide of an atomizer typically utilizes its own capillary action to transport liquid. However, the porosity of this guide is affected by various factors. For example, after prolonged use, impurities and deposits can gradually clog the pores of the guide, hindering normal liquid transport and leading to insufficient liquid supply. When the liquid supply is insufficient, the liquid around the heating element evaporates rapidly, exposing the heating element directly to a high-temperature environment. This causes residual aerosols to carbonize and coke, resulting not only in altered flavor but also potentially producing harmful substances that pose a potential threat to the user's health. Utility Model Content

[0004] This application provides an atomizing component and an atomizer to solve the problems of insufficient liquid supply and wicking during atomizer operation.

[0010] In some optional embodiments, the heating element includes a first extension, a second extension, and a third extension, the first extension and the third extension being respectively disposed on both sides of the second extension, the first extension, the second extension and the third extension all extending along the axial direction of the atomizing channel, and the distance from the first extension and the second extension to the axis of the atomizing channel is greater than the distance from the second extension to the axis of the atomizing channel.

[0011] In some optional embodiments, the atomizing assembly further includes an electrode portion for conductive connection between the heating element and the power supply assembly; the electrode portion includes a first conductive portion, a second conductive portion, and a third conductive portion continuously arranged along the axial direction of the atomizing channel, wherein the distance of the first conductive portion and the third conductive portion from the axis of the atomizing channel is greater than the distance of the second conductive portion from the axis of the atomizing channel.

[0014] This application also provides an atomizer, including the atomizing component as described above, the atomizer further including a liquid supply section, and the atomizing channel being in liquid communication with the liquid supply section.

[0015] According to the atomizing component and atomizer in this embodiment, since the atomizing component has an atomizing channel, the atomizing channel includes a first part, a second part and a third part. The first part and the third part are respectively located at both ends of the second part. The inner diameter of the first part and the third part is larger than the inner diameter of the second part, so that an atomizing channel with large sides and small middle is formed.

Detailed Implementation

[0025] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. 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.

[0026] 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.

[0027] The serial numbers assigned to components in this document, such as "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, the terms "connection" and "linkage" used in this application include both direct and indirect connections (linkages).

[0028] Before introducing the technical solution of this application, some terms used in this application will be explained.

[0029] "Aerosol" refers to a dispersion of solid or liquid particles in a gas. As used in this article, "aerosol" can generally refer to a substance that has been vaporized, aerosolized, sprayed or jetted, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0030] The atomizing matrix in this application is any suitable compound or mixture of compounds that facilitates aerosol formation during use, including but 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. It may also include nicotine, water, glycerol (also known as glycerol) having a higher boiling point than nicotine, propylene glycol, plant-based materials, or homogeneous plant substrates. The atomizing matrix is ​​generally a liquid with fluidity, which can be stored directly in a container or adsorbed and stored in a porous structure (e.g., absorbent cotton or porous ceramics).

[0031] Please see Figures 1 to 8 This application provides an atomizing device that can heat an atomizing substrate to generate an aerosol. The atomizing device includes a power supply component 100 and an atomizer 200. The power supply component 100 supplies power to the atomizer 200, which, when powered, heats the atomizing substrate.

[0032] In some embodiments, the power supply assembly 100 and the atomizer 200 are integrally formed. The power supply assembly 100 and the atomizer 200 are configured as a single integrated housing. This housing design facilitates the holding, operation, and carrying of the atomizing device.

[0033] In other embodiments, the power supply assembly 100 and the atomizer 200 are detachably connected, and the power supply assembly 100 and the atomizer 200 have separate housings to accommodate other related structures, which facilitates individual maintenance and replacement of the power supply assembly 100 or the atomizer 200, helps reduce user operating costs, and allows the use of atomizers 200 with different atomizing substrates on the same power supply assembly 100 to provide users with aerosols with different flavors.

[0034] The different atomizing substrates mentioned in this application can be atomizing substrates with different flavors, such as atomizing substrates with different fruit flavors like strawberry or blueberry, atomizing substrates with a minty flavor that can bring a cooling sensation, or the original atomizing substrate without added flavor.

[0035] The detachable connections mentioned in this application include, but are not limited to, threaded connections, snap-fit ​​connections, and magnetic connections.

[0036] The atomizer 200 includes a liquid supply section and an atomizing component 230. The liquid supply section is connected to the atomizing component 230 to supply the atomizing matrix required for the operation of the atomizing component 230. Specifically, the liquid supply section has a liquid storage chamber 220 for storing the atomizing matrix. A liquid passage is provided between the atomizing component 230 and the liquid storage chamber 220. When the atomizer 200 is working, the atomizing matrix in the liquid storage chamber 220 flows into the atomizing component 230, and the atomizing component 230 is energized to heat the atomizing matrix.

[0037] In addition, the atomizer 200 also includes a housing 210, which can be understood as an assembly of multiple components, with a liquid storage chamber 220 and a cavity for housing the atomizing component 230 formed inside. When the atomizer 200 and the power supply component 100 are integrally formed, the housing 210 here is different from the outer housing mentioned above. Specifically, multiple components belonging to the atomizer 200, including the atomizing component 230, are first housed in the housing 210, and then they are placed together with the power supply component 100 in the outer shell. When the atomizer 200 and the power supply component 100 are detachably connected, the housing 210 is equivalent to the outer shell of the atomizer 200 mentioned above.

[0038] In some embodiments, the atomizing assembly 230 may also have a separate atomizing tube on its exterior. The atomizing tube is disposed inside the housing 210, dividing the internal space of the housing 210 into two parts. A liquid storage chamber 220 is formed between the outer wall of the atomizing tube and the inner wall of the housing 210. The liquid storage chamber 220 can directly store the atomized matrix. Of course, a porous structure can also be provided inside the liquid storage chamber 220 to store the atomized matrix.

[0039] Please see Figure 2 An atomizing channel 231 is formed within the atomizing component 230. The atomizing channel 231 includes a first part 2311, a second part 2312, and a third part 2313. The first part 2311 and the third part 2313 are respectively disposed at both ends of the second part 2312. The inner diameters of the first part 2311 and the third part 2313 are larger than the inner diameter of the second part 2312.

[0040] In this application, the atomizing channel 231 serves as a channel for aerosol flow, and it maintains liquid-path communication with the liquid storage chamber 220. When the atomizer 200 starts operating or the user performs a suction action, based on the Bernoulli negative pressure principle, the airflow rapidly passes through the atomizing channel 231, causing a decrease in pressure within the atomizing channel 231 and creating a pressure difference with the liquid storage chamber 220. Under the influence of this pressure difference, the atomizing matrix in the liquid storage chamber 220 enters the atomizing channel 231 and is heated and atomized within it.

[0041] Due to the unique structure of the atomizing channel 231, which includes a second section 2312 with a smaller inner diameter located in the middle, and a first section 2311 and a third section 2313 with larger inner diameters located at both ends, the overall structure presents a special configuration with a smaller middle and larger sides. Regardless of whether the airflow flows from the first section 2311 to the second section 2312 or from the third section 2313 to the second section 2312, the flow velocity increases significantly when the airflow passes through the smaller inner diameter second section 2312. Based on the Venturi effect, the pressure in the second section 2312 decreases accordingly, which further increases the pressure difference between the second section 2312 and the liquid storage chamber 220. This greatly enhances the adsorption capacity of the atomizing matrix, accelerates the inflow of the atomizing matrix, and effectively ensures a sufficient supply of the atomizing matrix, avoiding the wicking phenomenon caused by insufficient liquid supply. This not only improves the taste of the aerosol but also extends the service life of the atomizer 200.

[0042] The Venturi effect, also known as the Venturi effect, refers to the phenomenon that a confined fluid experiences an increase in velocity when passing through a narrowed flow cross-section. According to Bernoulli's law, this increase in velocity is accompanied by a decrease in fluid pressure; that is, a low pressure is generated near a high-speed flowing fluid, thus producing an adsorption effect.

[0043] In some embodiments, the inner diameters of both the first portion 2311 and the third portion 2313 gradually decrease from the end furthest from the second portion 2312 to the end closest to the second portion 2312. Specifically, both the first portion 2311 and the third portion 2313 converge towards the second portion 2312, forming a funnel shape. The gradual decrease in the inner diameter of the first portion 2311 and the third portion 2313 can avoid liquid accumulation caused by abrupt changes in size, thereby ensuring a uniform distribution of the atomizing matrix within the atomizing channel 231.

[0044] In actual operation, when a user inhales, external air enters the atomization channel 231 from the first part 2311 with a larger inner diameter. This allows the initial airflow and the resulting aerosol to pass smoothly, reducing resistance. As the inner diameter of the atomization channel 231 gradually decreases into the second part 2312, the airflow speed increases instantaneously. Based on the Venturi effect, the pressure in the second part 2312 drops rapidly, creating a larger pressure difference with the liquid storage chamber 220. This allows the atomizing matrix in the liquid storage chamber 220 to be adsorbed into the atomization channel 231 at a faster rate, where it is rapidly heated and atomized by the atomization component 230, generating a large amount of aerosol. Subsequently, the aerosol is stably delivered to the user's mouth through the third part 2313, whose inner diameter increases again.

[0045] In some embodiments, the atomizing channel 231 has a smooth curved surface. The smooth curved surface guides the atomizing matrix to flow more evenly within the atomizing channel 231, avoiding liquid concentration or localized drying, allowing the atomizing matrix to be heated more fully during atomization, thereby improving the uniformity and consistency of the aerosol. Of course, the smooth curved surface also reduces the flow resistance of the aerosol, lowering the suction resistance during user inhalation, making inhalation easier and smoother. In some specific embodiments, the first portion 2311, the second portion 2312, and the third portion 2313 of the atomizing channel 231 are all curved surfaces. In other specific embodiments, the second portion 2312 is a straight line, and the first portion 2311 and the third portion 2313 gradually taper towards the second portion 2312 with curved surfaces.

[0046] Please see Figure 3 The atomizing component 230 includes a heating element 232 and an adsorption substrate 233. The heating element 232 is wound around a preset axis (also known as axis A) to define an atomizing channel 231. The adsorption substrate 233 has a receiving cavity 234. The outer side of the heating element 232 is attached to the cavity wall of the receiving cavity 234. The adsorption substrate 233 is used to adsorb and store the atomizing matrix, and the heating element 232 is used to heat the atomizing matrix to generate an aerosol. The heating element 232 unfolds into a planar structure. During the winding process, its middle part is stamped and bent to form a structure that is large on both sides and small in the middle, and an atomizing channel 231 with a small middle and large sides is defined inside it. The adsorption substrate 233 is made of a porous material, such as porous fiber or porous ceramic, which has an adsorption and storage function. The heating element 232 is attached to the cavity wall of its receiving cavity 234. After being energized, the heating element 232 can heat the atomizing matrix to generate an aerosol.

[0047] In some embodiments, the accommodating cavity 234 inside the adsorption substrate 233 has the same structural morphology as the wound heating element 232. For details, please refer to [link to relevant documentation]. Figure 4 The accommodating cavity 234 includes a first cavity 2341, a second cavity 2342, and a third cavity 2343. The second cavity 2342 is disposed between the first cavity 2341 and the third cavity 2343, and the inner diameter of the second cavity 2342 is smaller than the inner diameters of the first cavity 2341 and the third cavity 2343, so that the heating element 232 and the accommodating cavity 234 are fitted together. The first cavity 2341 and the first part 2311 are in corresponding positions, the second cavity 2342 and the second part 2312 are in corresponding positions, and the third cavity 2343 and the third part 2313 are in corresponding positions.

[0048] It should be further explained that the bonding arrangement in this application includes direct contact between the heating element 232 and the inner wall of the accommodating cavity 234, or indirect contact between the heating element 232 and the adsorption substrate 233 by providing a liquid guiding element between the heating element 232 and the accommodating cavity 234. The liquid guiding element has good liquid guiding performance and can also be made of porous materials, such as liquid guiding cotton made of porous cotton fibers.

[0049] In other embodiments, please refer to Figure 5 The atomizing component 230 includes an adsorption substrate 233 and multiple heating elements 232. The adsorption substrate 233 has an atomization channel 231. The multiple heating elements 232 are attached to the inner surface of the atomization channel 231 and are spaced apart along the circumference of the atomization channel 231. The adsorption substrate 233 is used to adsorb and store the atomization matrix, and the heating elements 232 are used to heat the atomization matrix to generate an aerosol. In this embodiment, the adsorption substrate 233 directly defines the atomization channel 231. That is, the first cavity 2341 inside the adsorption substrate 233 is the first part 2311 of the atomization channel 231, the second cavity 2342 is the second part 2312 of the atomization channel 231, and the third cavity 2343 is the third part 2313 of the atomization channel 231. The adsorption substrate 233 can not only adsorb and store the atomization matrix to provide the atomization matrix required for the operation of the heating element 232, but also serve as a support structure for the heating element 232. Specifically, since the multiple heating elements 232 are spaced apart from each other and there is no connection structure between them, the adsorption substrate 233 causes the multiple heating elements 232 to be arranged circumferentially according to the atomization channel 231.

[0050] In some embodiments, please refer to Figure 6 The heating element 232 includes a first extension 2321, a second extension 2322, and a third extension 2323. The first extension 2321 and the third extension 2323 are respectively disposed on both sides of the second extension 2322. The first extension 2321, the second extension 2322, and the third extension 2323 all extend along the axial direction of the atomizing channel 231. The distance from the first extension 2321 and the second extension 2322 to the axis A of the atomizing channel 231 is greater than the distance from the second extension 2322 to the axis A of the atomizing channel 231. The first extension 2321, the second extension 2322, and the third extension 2323 of the heating element 232 are arranged sequentially along the axial direction of the atomizing channel 231, forming a special structure that is smaller in the middle and larger on both sides, consistent with the structural shape of the atomizing channel 231. Thus, the heating element 232 can directly define the atomizing channel 231, or multiple heating elements 232 can be enclosed to form a structure that is interference-fitted with the atomizing channel 231.

[0051] In some embodiments, the first extension segment 2321 and the third extension segment 2323 have the same axial extension length in the atomization channel 231, which makes the airflow acceleration and deceleration uniform, providing a stable inlet and outlet channel for the airflow and providing users with a stable suction experience.

[0052] In some embodiments, the outer contour of the adsorption substrate 233 is a cylindrical structure (including a near-cylindrical structure). This facilitates the connection between the adsorption substrate 233 and other components of the atomizer 200, eliminating the need to modify other structural components in the conventional atomizer 200 and improving the installation stability of the atomization assembly 230. The adsorption substrate 233 can be a cylindrical structure with open ends and closed sides, with the open ends used for gas passage and insertion of the heating element 232. However, due to the special structure of the wound heating element 232, it is easy for the heating element 232 to be squeezed and deformed when inserted from both ends of the adsorption substrate 233, and the installation is also relatively inconvenient. Based on this, the sides of the adsorption substrate 233 do not need to be closed. Specifically, cuts are made along the axial direction at any position on the side of the adsorption substrate 233 to facilitate opening the adsorption substrate 233 to place the heating element 232. Of course, in order to better open or close the cavity inside the adsorption substrate 233, two cuts are provided on the side of the adsorption substrate 233, and one of the cuts is provided with a hinge structure, which can be a hinge, hinge, etc.

[0053] In some embodiments, the adsorption substrate 233 is made of a porous material. The porous material may be porous cotton fiber, porous ceramic, or the like. For example, the adsorption substrate 233 is adsorption cotton made of porous cotton fiber.

[0054] In some embodiments, the heating element 232 includes a heating mesh, which includes a plurality of heating lines 2324. The plurality of heating lines 2324 extend circumferentially along the atomization channel 231 and are arranged in parallel sequentially along the axis A of the atomization channel 231. The heating element 232 can be constructed in various ways. For example, please refer to... Figure 7 The heating element 232 is composed of multiple resistance wires that are interconnected to form a mesh structure. For example, the heating element 232 is a tube made of conductive material with multiple hollow structures on it. These hollow structures are connected by multiple heating lines 2324 to form a mesh structure as well.

[0055] Furthermore, the dimensions of the heating lines 2324 located at both ends in the radial direction (perpendicular to axis A) of the atomization channel 231 are greater than the dimensions of the heating line 2324 located in the middle in the radial direction of the atomization channel 231.

[0056] In some embodiments, the atomizing assembly 230 further includes an electrode portion 240, which is used to realize the electrical connection between the heating element 232 and the power supply assembly 100.

[0057] For some specific embodiments, please refer to [link / reference]. Figure 7 The heating element 232 is connected to two electrode sections 240, namely a positive electrode section and a negative electrode section. The heating element 232 is connected to the positive and negative terminals of the power supply assembly 100 through the positive electrode section and the negative electrode section.

[0058] In some embodiments, please refer to Figure 8 The electrode portion 240 includes a first conductive portion 241, a second conductive portion 242, and a third conductive portion 243 continuously arranged along the axis A of the atomization channel 231. The distances of the first conductive portion 241 and the third conductive portion 243 from the axis A of the atomization channel 231 are greater than the distances of the second conductive portion 242 from the axis of the atomization channel 231, so that the electrode portion 240 also forms a structure that tapers inward in the middle, consistent with the structural shape of the heating element 232. Specifically, the positive electrode portion and the negative electrode portion are disposed opposite each other at both ends of the heating element 232. The first conductive portion 241 and the third conductive portion 243 of the positive electrode portion and the negative electrode portion both extend inward towards the second conductive portion 242, and the positive electrode portion and the negative electrode portion cooperate to form a structure that is smaller in the middle and larger on both sides.

[0059] Furthermore, the electrode portion 240 also includes a fourth conductive portion 244, which extends to be conductively connected to the power supply component. The shape of the fourth conductive portion 244 is not limited and can be either straight or curved.

[0060] In some embodiments, when multiple heating elements 232 are provided, they are connected in parallel, allowing them to operate independently or collaboratively. Specifically, each heating element 232 has a positive electrode and a negative electrode that are independently connected to the power supply assembly 100, or they share a positive or negative electrode. This allows selection of one heating element 232 to operate independently or multiple heating elements 232 to operate together in the parallel circuit. Since each heating element 232 can be turned on or off independently, independent control of the heating elements 232 allows for the operation of a single heating element 232 or several heating elements 232 to achieve zoned heating.

[0061] In other embodiments, multiple heating elements 232 can also work synchronously, that is, multiple heating elements 232 are connected in series and electrically connected to the positive electrode and the negative electrode. The multiple heating elements 232 are arranged in a ring array to uniformly generate aerosol around the circumference of the atomization channel 231.

[0062] 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.
