In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid the core part of the present application being overwhelmed by excessive description. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0029] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the specification and the drawings are only for clearly describing a certain embodiment, and do not mean to be the necessary composition and / or sequence.

[0030] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described, and do not have any sequential or technical meaning. And as used in this application, "connection" and "coupling", unless otherwise specified, both include direct and indirect connection (coupling).

[0031] This application provides an atomization device, which can be used to heat an atomization matrix to generate an aerosol that can be used.

[0032] It should be noted that the aerosol referred to in the terms refers to a dispersion of solid particles or liquid particles in a gas. As used herein, "aerosol" generally can be used to refer to a substance that has been vaporized, atomized, in the form of a spray or jet, or otherwise converted from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0033] As used herein, the term "atomization matrix" refers to any suitable compound or mixture of compounds that facilitates the formation of an aerosol (e.g., a stable aerosol that substantially resists thermal degradation at the operating temperature of the system) during use. Suitable atomization 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 glycerol mono-, di- or triacetate; and aliphatic esters of mono-, di- or polycarboxylic acids, such as dimethyl dodecanedioate and dimethyl tetradecanedioate.

[0034] The atomization matrix can include nicotine. The atomization matrix can include water. The atomization matrix can include glycerol (also known as glycerin) which has a boiling point higher than nicotine. The atomization matrix can include propylene glycol. The atomization matrix can include plant-based materials. The atomization matrix can include a homogeneous plant matrix material. The homogeneous plant matrix material can contain volatile compounds. These compounds can be released from the atomization matrix when heated. The atomization matrix can be contained in a container to form a columnar structure body with a preset length, etc.

[0035] Please refer to Figure 1, the atomization device includes a power supply component and an atomizer. The atomizer includes a housing 100, a mouthpiece 200, a heating component 300, a liquid storage member 400, and a mounting base 500. The housing 100 can be understood as a collection of related components that form the overall outer contour of the atomization device. For example, the housing 100 can be assembled by combining one or more components, and corresponding assembly structures are provided inside or on the wall of the housing 100 to assemble other components of the atomization device to the housing 100. With the housing 100, users can carry, move, operate, and use the atomization device.

[0036] The housing 100 has a liquid storage chamber 110 and an atomization chamber 120. An atomization matrix is provided in the liquid storage chamber 110. The mouthpiece 200 and the mounting base 500 are oppositely arranged at both ends of the housing 100. The mouthpiece 200 is communicated with the atomizer. The liquid storage member 400 is arranged in the atomization chamber 120. The heating component 300 is attached to the liquid storage member 400. The liquid storage member 400 is a liquid storage cotton or made of a porous ceramic material. The liquid storage member 400 can be communicated with the liquid storage chamber 110 to enable the atomization matrix to flow to the liquid storage member 400. The heating component 300 can heat the atomization core to form an aerosol, and the user completes the use (suction) of the aerosol through the mouthpiece 200. The power supply component includes a battery (not shown in the figure), a PCB control circuit board (not shown in the figure), and a conductive electrode 600. The conductive electrode 600 is arranged on the mounting base 500 and can be electrically connected to the heating component 300 by means of a connecting wire, plugging, or contacting. The battery provides the power required for the heating component 300 to work, and the PCB control circuit board can adjust the working power or working curve (temperature curve) of the heating component 300.

[0037] To effectively fix the liquid storage member 400, an installation bracket 700 is further included. The installation bracket 700 is arranged in the atomization chamber 120, and the liquid storage member 400 is arranged on the installation bracket 700. To ensure the sealing performance of the entire atomization device during operation, a sealing ring 800 and a bracket seal 900 are provided between the installation bracket 700 and the housing 100. The installation bracket 700 and the sealing ring 800 can jointly seal the atomization matrix in the liquid storage chamber 110, and the installation bracket 700 and the bracket seal 900 are used to seal the atomization chamber 120 and the liquid storage chamber 110. Both the sealing ring 800 and the bracket seal 900 can be made of silica gel, with good sealing effect, high temperature resistance, and controllable material cost.

[0038] Please refer to Figures 2 to 8, the heating component 300 includes a heating element 310 and an electrode part 320. The heating element 310 has an extended length. Along its length direction, the electrode part 320 is electrically connected to both ends of the heating element 310 respectively. The electrode part 320 is electrically connected to the conductive electrode 600 of the power supply component through a connecting wire. The heating element 310 is disposed in a fitting manner on the liquid storage member 400. After being powered on, the heating element 310 can generate heat to heat the atomization matrix.

[0039] In one embodiment, there are two electrode parts 320, which are the positive electrode and the negative electrode in the circuit connection, that is, it includes a first electrode part 321 and a second electrode part 322, which are respectively arranged at both ends of the heating element 310 in the length direction and are electrically connected to the conductive electrode 600 through two connecting wires respectively.

[0040] Of course, in other embodiments, when there are multiple heating elements 310 and it is necessary to control the operation of the heating element 310 separately, the number of electrode parts 320 can be determined according to requirements. For example, two electrode parts 320 are provided corresponding to each heating element 310, or multiple heating elements 310 share the same positive or negative electrode part 320, or multiple heating elements 310 can share the positive and negative electrode parts 320 at the same time. There can be multiple combination methods according to requirements, which will not be elaborated here.

[0041] Please refer to Figure 3 , the heating element 310 is in a waveform structure (or mountain peak structure), including a plurality of wave crest segments 311 and a plurality of wave trough segments 312 arranged along its length direction. The peak values of at least two wave crest segments 311 among the plurality of wave crest segments 311 are different, and / or the valley values of at least two wave trough segments 312 among the plurality of wave trough segments 312 are different; the wave crest segments 311 and the wave trough segments 312 are arranged in sequence along the length direction (direction A in the figure), and a wave trough segment 312 is provided between every two adjacent wave crest segments 311.

[0042] It should be further noted that in a waveform structure (or mountain peak structure), the highest point of the protrusion is called the wave crest, and the lowest point of the depression is called the wave trough. The wave crest segment 311 refers to the protruding part, and the wave trough segment 312 refers to the depressed part. Define a 0 scale in the waveform structure (or mountain peak structure) and establish a coordinate system as shown in Figure 3 As shown, with the 0 scale as the reference in a waveform structure (or mountain peak structure), as shown in Figure 3 As shown, the peak value refers to the straight-line distance H1 from the wave crest to this reference, and the valley value refers to the straight-line distance H2 from the wave trough to this reference. In a waveform structure (or mountain peak structure), define the dimension of each wave crest segment 311 and each wave trough segment 312 along the length direction of the waveform structure (or mountain peak structure) as the wave width.

[0043] It should be further noted that the "multiple" mentioned in this article includes two or more.

[0044] Since the heating element 310 has a waveform structure (or mountain peak structure) composed of a plurality of wave crest segments 311 and a plurality of wave trough segments 312, in the direction perpendicular to its length direction, the heating range and area of the heating element 310 can be increased, a good heating effect can be achieved, and the heating area can be prevented from being too concentrated in the direction perpendicular to the length direction of the heating element 310, thereby avoiding insufficient atomization caused by insufficient heating or carbonization of the wick due to concentrated heating, effectively improving the user experience, and also improving the service life of the heating element 310.

[0045] In one embodiment, the length direction of the heating element 310 and the axial direction of the liquid storage member 400 are perpendicular to each other, which can increase the heating range in the length direction of the liquid storage member 400 and make the atomization matrix on the axis of the liquid storage member 400 heated evenly. Of course, in order to effectively ensure uniform heating on the circumference of the liquid storage member 400, the waveform structure (or mountain peak structure) can be arranged around the liquid storage member 400.

[0046] In one embodiment, the heating element 310 includes a plurality of wave crest segments 311 and a plurality of wave trough segments 312 arranged along its length direction. At least two of the plurality of wave crest segments 311 have different peak values, and the trough values of the plurality of wave trough segments 312 are the same. The arrangement of the wave crest segments 311 with different peak values can achieve the setting of heating regions in different regions in the direction perpendicular to the length direction (such as Figure 3 shown by Y in the figure), thereby increasing the heating range.

[0047] In one embodiment, the plurality of wave crest segments 311 include a first wave crest segment 3111 and a second wave crest segment 3112, and the peak value of the first wave crest segment 3111 is greater than the peak value of the second wave crest segment 3112; the plurality of first wave crest segments 3111 are arranged at intervals along the length direction; the plurality of second wave crest segments 3112 are arranged at intervals along the length direction; the wave trough segment 312 is connected between two adjacent first wave crest segments 3111, two adjacent second wave crest segments 3112, and / or between an adjacent first wave crest segment 3111 and a second wave crest segment 3112. By arranging the wave trough segment 312 between two first wave crest segments 3111, two second wave crest segments 3112, or between a first wave crest segment 3111 and a second wave crest segment 3112, that is, no matter how the wave crest segments 311 are arranged, a wave trough segment 312 is provided between two wave crest segments 311, the entire heating region can be made uniform.

[0048] Please refer to Figure 3 , in one embodiment, the plurality of first wave crest segments 3111, wave trough segments 312, and second wave crest segments 3112 are alternately arranged in sequence along the length direction, and both ends of the wave trough segment 312 are respectively connected to the first wave crest segment 3111 and the second wave crest segment 3112, that is, the first wave crest segment 3111 and the second wave crest segment 3112 are arranged in a "one high and one low" manner.

[0049] Please refer to Figure 4 In one embodiment, a plurality of first peak segments 3111 are arranged at intervals along the length direction, and a plurality of second peak segments 3112 are arranged at intervals along the length direction. The first peak segments 3111 and the second peak segments 3112 are arranged in a "two-high-one-low" manner, that is, two first peak segments 3111 and one second peak segment 3112 are arranged in a cyclic and alternating manner in sequence. Adjacent two first peak segments 3111 and between the first peak segment 3111 and the second peak segment 3112 are all connected by a trough segment 312.

[0050] Of course, in other embodiments, it can also be arranged in a free combination manner such as "two-high-two-low" (as shown in Figure 5 ), "one-high-two-low", "two-high-three-low" or "three-high-two-low", etc., which will not be listed one by one here.

[0051] In one embodiment, similar to the setting of the peak segments 311 with different peaks, the heating element 310 further includes a plurality of peak segments 311 and a plurality of trough segments 312 arranged along its length direction. The peaks of the plurality of peak segments 311 are the same, and the trough values of at least two of the plurality of trough segments 312 are different.

[0052] In one embodiment, the widths of the peak segments 311 and the trough segments 312 are exactly the same to facilitate processing and installation.

[0053] Since there are different components in the atomization matrix and the fully atomized temperature of each component is different, at the same temperature, there is a situation where some components are already fully atomized and some components are partially atomized. These different components are mixed at the mouthpiece 200 used by the user for the user to use. When the components are uneven, it will affect the taste of the aerosol. In order to effectively ensure that each component in the atomization matrix can be fully atomized, it is necessary to divide different temperature zones for the entire heating element 310, that is, divide into multiple temperature intervals at the atomization temperature of the atomization matrix, such as divided into a high temperature zone, a medium temperature zone and a low temperature zone. These three temperature intervals correspond to the fully atomized temperatures of different components, so as to ensure the uniform composition of the aerosol obtained by the user during use.

[0054] In the same circuit, as a conductor, the resistance of the heating element 310 is related to the cross-sectional area, that is, related to its diameter. The larger the diameter, the greater the resistance, the more heat is generated, and the higher the heating temperature of the area where it is located. Therefore, different diameters can be set for different parts of the heating element 310 to achieve different temperature zoning.

[0055] In one embodiment, the peak section 311 includes a first peak section 3111 and a second peak section 3112. The trough values of the multiple trough sections 312 are the same, that is, there is only one type of trough section 312. At least two of the first peak section 3111, the second peak section 3112, and the trough section 312 have different diameters, so that temperature zoning can be achieved at the first peak section 3111, the second peak section 3112, and the trough section 312.

[0056] It should be further noted that the classification of the first peak section 3111 and the second peak section 3112 is based on the peak value, which does not mean that the materials, diameters, etc. of the multiple first peak sections 3111 are the same, nor does it mean that the materials, diameters, etc. of the multiple second peak sections 3112 are the same. For example, the first peak section 3111 and the second peak section 3112 can be set to have different diameters according to needs. Multiple different diameters can also be set among the multiple first peak sections 3111. Similarly, multiple different diameters can also be set among the multiple second peak sections 3112.

[0057] In one embodiment, the diameter of the first peak section 3111 is greater than the diameter of the second peak section 3112, that is, the temperatures of the first peak section 3111 and the second peak section 3112 are different, and the temperature of the first peak section 3111 is greater than the temperature of the second peak section 3112, which can relatively make the components with a higher atomization temperature fully atomized.

[0058] In one embodiment, the diameters of both the first peak section 3111 and the second peak section 3112 are greater than the diameter of the trough section 312. The diameters of the first peak section 3111 and the second peak section 3112 can be the same or different, and the atomization temperatures of the components that can be atomized correspondingly are all higher than the components heated and atomized by the trough section 312.

[0059] In one embodiment, the trough values of the multiple trough sections 312 are the same, the diameter of the first peak section 3111 is greater than the diameter of the second peak section 3112, and the diameter of the second peak section 3112 is greater than the diameter of the trough section 312. That is, the first peak section 3111, the second peak section 3112, and the trough section 312 are successively divided into a high-temperature zone, a medium-temperature zone, and a low-temperature zone, so that different components can all achieve good atomization. Using a combination of materials with three diameters to form the heating element 310 can not only ensure the atomization effect of multiple components in the atomization matrix, but also simplify the structure and facilitate processing and production.

[0060] In one embodiment, the value range of the diameter of the first peak section 3111 can be 0.12 mm - 0.15 mm, the value range of the diameter of the second peak section 3112 can be 0.08 mm - 0.12 mm, and the value range of the diameter of the trough section 312 can be 0.06 mm - 0.08 mm. The heating effect is better within this range.

[0061] Please refer to Figure 6 In one embodiment, the heating element 310 includes a first heating unit 313 and a second heating unit 314. The first heating unit 313 and the second heating unit 314 are arranged in a direction perpendicular to their length directions, and the first heating unit 313 and the second heating unit 314 are symmetrically arranged along a straight line (such as I shown in the figure) in their length directions. The first heating unit 313 and the second heating unit 314 also each include a plurality of valley segments 312 and a plurality of peak segments 311. At least two of the plurality of peak segments 311 have different peak values, and / or at least two of the plurality of valley segments 312 have different valley values. The first heating unit 313 and the second heating unit 314 share the electrode portion 320, and together with the electrode portion 320, they form a substantially centrosymmetric structure, such as a closed ring structure.

[0062] Please refer to Figure 7 and Figure 8 In one embodiment, there are a plurality of heating elements 310. The plurality of heating elements 310 are arranged at intervals in a direction perpendicular to their length directions (such as the Y direction in Figure 7 and Figure 8 ). The plurality of heating elements 310 share the electrode portion 320 of the positive electrode and the negative electrode, which can simplify the structure and facilitate installation. Of course, in other embodiments, in order to control and adjust heating in different regions or adjust the heating power, any one or more of the heating elements 310 can be selected to be powered on for operation. Therefore, the plurality of heating elements 310 can be respectively provided with electrode portions 320 to achieve independent operation.

[0063] In one embodiment, each peak segment 311 and each valley segment 312 are formed by bending one or more heating wires to form the heating element 310; the bending path of the heating wire is a smooth curve, so that the entire structure of the heating element 310 has a smooth transition, without right angles or sharp boundaries, thus it is not easy to cause local instantaneous temperature to be too high and generate carbon deposition, and the service life of the heating element 310 can be improved.

[0064] The above uses specific examples to elaborate on the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, according to the idea of the present application, several simple deductions, deformations or substitutions can also be made.
