However, the atomization matrix content in the atomization device is limited. When the user uses it, the atomization matrix is ​​sufficient at the beginning. As the atomization matrix is ​​consumed, its capacity gradually decreases, resulting in different atomization matrix contents at different time periods under the same heating conditions, resulting in sufficient aerosol in the early stage of use and less aerosol in the later stage, affecting the user's experience.

DETAILED DESCRIPTION

[0023] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. 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, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and 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 the general technical knowledge in the art.

[0024] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in order in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the composition and / or order are necessary.

[0025] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0026] Common atomizers use bottom heating and heat exchange methods. A heat exchange structure is set at the bottom of the atomizing matrix, and the heat exchange structure is set at the same height in its extension direction, that is, the distance from the atomizing matrix to the cross section of the entire heat exchange structure is consistent, and the heat exchange distance of the airflow on the cross section of the heat exchange structure outlet is the same, so that the airflow heat exchange efficiency is consistent, and the airflow (including the central airflow and the peripheral airflow) flowing into the atomizing matrix at the cross section of the heat exchange structure outlet is consistent in temperature, so that the atomizing matrix on the same cross section is heated and atomized by the airflow under the same conditions at the same time to form an aerosol. However, based on the limited content of the atomizing matrix in the atomizing device, as the puffing time increases, the atomizing matrix is ​​sufficient in the early stage, and the aerosol content generated is high, and the atomizing matrix content is reduced in the later stage, and the aerosol content generated is less, so that the aerosol content is inconsistent before and after the entire puffing process, affecting the customer's experience. In order to solve the above technical problems, the present application provides the following solutions.

[0027] refer to Figure 7 The present application provides an atomization device, including a host component 100 and a heat exchange structure. The host component 100 is provided with a accommodating cavity, and the accommodating cavity is used to accommodate an atomization matrix and the heat exchange structure.

[0028] The host assembly 100 is a collection of related functional components that constitute the overall outline structure of the atomizing device. The user can carry, operate and use the atomizing device by holding the host assembly 100; for example, the host assembly 100 may include a main shell, a control assembly including a battery, and various pipes and fittings. Generally, a plurality of cavities with different functions are arranged or formed in the host assembly 100, and the plurality of cavities include a receiving cavity, which is used to accommodate the atomizing matrix and the heat exchange structure. The heat exchange structure is arranged at one end of the atomizing matrix, and is used to provide a heating channel for the airflow to be flowed into the atomizing matrix. The two ends of the receiving cavity are connected to the external space, one end is used for the airflow to enter the receiving cavity, and after being heated by the heat exchange structure to form a hot airflow, it flows into the atomizing matrix, and the other end is used for the airflow (including the hot airflow and the aerosol generated by the atomizing matrix) flowing through the atomizing matrix to be discharged from the main shell.

[0029] It should be noted that the atomized matrix can be a solid medium material, a semi-solid medium material or a liquid material capable of producing volatile substances. Generally, based on the different forms of the materials, the atomized matrix can be packaged by packaging materials or can be arranged in a container.

[0030] It should be further explained that the specific structure of the host assembly 100 can refer to the prior art and will not be described in detail here. The heat exchange structure and its related structures are mainly described in detail below.

[0031] Please refer to Figure 1-6 The heat exchange structure includes a heat exchange body 200, which includes a first heat exchange part 210 and a second heat exchange part 220. The first heat exchange part 210 is provided with a plurality of first heat exchange channels 211, which are used to provide a heating channel for a part of the airflow flowing into the atomizing matrix. The second heat exchange part 220 is provided with a plurality of second heat exchange channels 221, which are used to provide a heating channel for another part of the airflow flowing into the atomizing matrix. The first heat exchange channel 211 has a first heat exchange distance H1, and the second heat exchange channel 221 has a second heat exchange distance H2. The first heat exchange distance H1 and the second heat exchange distance H2 are different, so that the temperature of the airflow flowing into the atomizing matrix through the first heat exchange channel 211 and the second heat exchange channel 221 is different. The plurality of first heat exchange channels 211 are isolated from each other, and the plurality of second heat exchange channels 221 are also isolated from each other.

[0032] The atomized substrate is generally a columnar structure with a preset length, and has a top and a bottom, the bottom of which is arranged close to the heat exchanger 200, and the heat exchanger 200 heats the atomized substrate by heating the airflow at its bottom. Generally, all areas on the entire bottom cross section of the atomized substrate are in contact with the airflow under the same conditions at the same time, and are atomized and heated synchronously.

[0033] In the present application, in terms of the overall heat exchange or heating efficiency, the entire heat exchanger 200 is divided into two areas, each area corresponding to a different area on the cross-section of the atomization matrix. By changing the temperature of the air flow flowing into different areas, step-by-step heating and atomization of different areas are achieved to ensure that the aerosol formed during the entire use process is uniform.

[0034] Through the structural design of the first heat exchange part 210 and the second heat exchange part 220, the first heat exchange distance H1 and the second heat exchange distance H2 corresponding to the first heat exchange channel 211 and the second heat exchange channel 221 are different, so that the heat exchange effects of the airflows flowing through the first heat exchange channel 211 and the second heat exchange channel 221 are different. Finally, the airflow temperatures coming out of the first heat exchange part 210 and the second heat exchange part 220 are different, so that the high temperature first causes the atomization matrix to be atomized to form an aerosol, and the low temperature reaches the atomization temperature condition of the atomization matrix later as the heat exchange accumulates, so that the atomization matrix corresponding to this part is atomized to form an aerosol later, so that the atomization matrix on the same cross-section is atomized in different regions to ensure that the content of the atomization matrix is ​​basically consistent during the entire use process, so as to even out the content of the aerosol during the entire use process, thereby improving the user experience.

[0035] The heat exchanger 200 can be made of a metal or alloy material with a high thermal conductivity. A heating body 300 is arranged around the heat exchanger 200 in the accommodating cavity 110. The heating body 300 is electrically connected to the control component in the host component 100. The control component is used to supply power to the heat exchanger 200 to cause the heat exchanger 200 to generate heat, thereby allowing the heat exchanger 200 to heat the airflow flowing through it.

[0036] Of course, the heat exchanger 200 can also be made of ferromagnetic materials or alloy materials containing elements such as iron, nickel, cobalt, and titanium, or can be made of inorganic non-metallic materials with ferromagnetic properties such as magnetized ceramics and carbon fibers; by arranging an electromagnetic coil around the heat exchanger 200 in the accommodating cavity 110, the electromagnetic coil is electrically connected to the control component in the main engine component 100, and the control component is used to supply power to the heat exchanger 200, the electromagnetic coil can be used to provide a changing electromagnetic field environment for the heat exchanger 200, causing the heat exchanger 200 to generate heat under the action of the alternating magnetic field, thereby heating the airflow flowing through it.

[0037] refer to Figure 1 and Figure 3 The end of the first heat exchange part 210 close to the atomizing substrate is a first end face 212, and the end of the second heat exchange part 220 close to the atomizing substrate is a second end face 222. Along the extension direction of the heat exchange body 200, the first end face 212 is protruded relative to the second end face 222. The end of the first heat exchange part 210 facing away from the atomizing substrate is aligned with the end of the second heat exchange part 220 facing away from the atomizing substrate. The first heat exchange distance H1 is greater than the second heat exchange distance H2, thereby strengthening the airflow entering the first heat exchange part 210, so that the atomizing substrate corresponding to the first heat exchange part 210 is first atomized and heated, and the atomizing substrate corresponding to the second heat exchange part 220 is later atomized and heated, so that the content of the atomized substrate that can be atomized and heated is consistent during the entire use process, thereby uniforming the aerosol content.

[0038] In this embodiment, in order to further clarify the zoned heating and atomization of the atomized substrate, the distance between the first end face 212 and the atomized substrate is smaller than the distance between the second end face 222 and the atomized substrate, that is, the outlet position of the first heat exchange part 210 is closer to the atomized substrate, and even the first end face 212 is in contact with the atomized substrate, so that the airflow does not pass through other components for conduction (such as air), and can directly heat the atomized substrate, thereby reducing heat loss during conduction and improving heat exchange and heating efficiency.

[0039] Accordingly, in order to make the atomized substrate corresponding to the second heat exchange part 220 be atomized and heated first, the atomized substrate corresponding to the first heat exchange part 210 is atomized and heated later, refer to Figure 4 and Figure 6The end of the first heat exchange part 210 close to the atomizing matrix is ​​a first end face 212, and the end of the second heat exchange part 220 close to the atomizing matrix is ​​a second end face 222. Along the extension direction of the heat exchange body 200, the first end face 212 is recessed relative to the second end face 222, and the end of the first heat exchange part 210 facing away from the atomizing matrix is ​​aligned with the end of the second heat exchange part 220 facing away from the atomizing matrix.

[0040] In this embodiment, the distance between the first end face 212 and the atomizing substrate is greater than the distance between the second end face 222 and the atomizing substrate, that is, the outlet position of the second heat exchange part 220 is closer to the atomizing substrate, and the second end face 222 even abuts against the atomizing substrate, so that the airflow does not pass through other components for conduction (such as air), and can directly heat the atomizing substrate, thereby reducing heat loss during conduction and improving heat exchange and heating efficiency.

[0041] It should be further explained that, the statement in the present application that one part of the atomized matrix is ​​atomized and heated first and the other part is atomized and heated later does not mean that the other part of the atomized matrix does not change when one part of the atomized matrix is ​​atomized and heated. Rather, when one part of the atomized matrix is ​​atomized and heated first, a small amount of the other part of the atomized matrix is ​​also atomized and heated, but relatively less, and the content of the atomized matrix changes less.

[0042] From the perspective of the structural construction of the heat exchanger 200, the central axis of the first heat exchange channel 211 and the central axis of the second heat exchange channel 221 are straight lines distributed along the extension direction of the heat exchanger 200, and the first heat exchange distance H1 and the second heat exchange distance H2 are straight line distances along the extension direction of the heat exchanger 200. Holes can be drilled directly on the first heat exchange part 210 or the second heat exchange part 220 along the length direction thereof, which is simple to process, and is conducive to reducing costs and improving processing efficiency.

[0043] In one embodiment, the second heat exchange portion 220 is arranged around the first heat exchange portion 210, the first heat exchange channels 211 are arranged in sequence along the geometric center of the first heat exchange portion 210 toward the geometric edge of the first heat exchange portion 210, and the second heat exchange channels 221 are arranged in sequence along the geometric edge of the first heat exchange portion 210 toward the geometric edge of the second heat exchange portion 220. The first heat exchange channels 211 are used to provide a heating channel for the central airflow flowing into the atomizing matrix, and the second heat exchange channels 221 are used to provide a heating channel for the peripheral airflow flowing into the atomizing matrix.

[0044] Through the above-mentioned structural construction, the airflow entering the center and the periphery of the atomized substrate passes through different heating channels and finally has different temperatures, thereby achieving distributed heating atomization of the periphery and the center of the atomized substrate.

[0045] refer to Figure 3The first heat exchange distance H1 is greater than the second heat exchange distance H2, so that the air flow temperature passing through the first heat exchange channel 211 (or the first heat exchange part 210) is greater than the air flow temperature passing through the second heat exchange channel 221 (or the second heat exchange part 220), so that the atomized matrix corresponding to the first heat exchange part 210 is atomized and heated first.

[0046] refer to Figure 2 In order to further enhance the intensity of the airflow passing through the first heat exchange channel 211 (or the first heat exchange part 210) so that more airflow can flow in from the center of the atomizing substrate to atomize and heat it, the orthographic projection area of ​​the first heat exchange channel 211 in the extension direction of the heat exchange body 200 is larger than the orthographic projection area of ​​the second heat exchange channel 221 in the extension direction of the heat exchange body 200, thereby increasing the volume of the airflow flowing through the first heat exchange part 210. Combined with the longer first heat exchange distance setting, the airflow flowing into the center of the atomizing substrate is stronger than that on the surrounding side.

[0047] The orthographic projections of the first heat exchange channel 211 and the second heat exchange channel 221 in the extension direction of the heat exchange body 200 are circular, elliptical or regular polygonal.

[0048] Furthermore, based on the structural limitations of the existing atomizer, the first heat exchange distance H1 is 2.5 times the second heat exchange distance H2, for example, the first heat exchange distance H1 is 5 mm, and the second heat exchange distance H2 is 2 mm. This ensures the suction experience during the entire use process, and because the first heat exchange portion 210 is arranged in the middle, and the second heat exchange portion 220 is arranged around the first heat exchange portion 210, under the same aperture, the number of second heat exchange channels 221 is greater than the number of first heat exchange channels 211, thereby avoiding affecting the suction experience. When the orthographic projections of the first heat exchange channel 211 and the second heat exchange channel 221 in the extension direction of the heat exchange body 200 are circular, the diameter of the first heat exchange channel 211 is greater than the diameter of the second heat exchange channel 221. The first heat exchange part 210 and the second heat exchange part 220 are both roughly columnar structures with a preset length, and are both consistent with the extension direction of the heat exchanger 200. The cross-section of the first heat exchange part 210 in the extension direction of the heat exchanger 200 is circular, and the cross-section of the second heat exchange part 220 in the extension direction of the heat exchanger 200 is an annular structure concentric with the first heat exchange part 210. The cross-sections of the two together constitute the cross-section of the heat exchanger 200 in its extension direction. In order to effectively ensure the enhancement of the central airflow, the size of the circular cross-section of the first heat exchange part 210 is half of the cross-sectional size of the entire heat exchanger 200, that is, the area is one-fourth.

[0049] refer to Figure 6In contrast, in order to enhance the airflow flowing into the periphery of the atomized substrate, the first heat exchange distance H1 is smaller than the second heat exchange distance H2. The second heat exchange distance H2 is 2.5 times the first heat exchange distance H1. For example, the first heat exchange distance H1 is 2 mm, and the second heat exchange distance H2 is 5 mm.

[0050] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
