Description

Technical Field

[0001] This disclosure relates to the field of atomization technology, and more specifically, to a non-contact heating component and atomization device for an atomization apparatus. Background Technology

[0002] Cigarette smoking devices are electronic delivery systems used to generate an aerosol from an atomizing matrix for a user to inhale. The atomizing matrix can be a liquid (e.g., e-liquid) or a solid or gel (e.g., tobacco paste). However, existing cigarette smoking devices suffer from problems such as scorching, uneven heating, and difficulty in controlling the heating temperature when heating the atomizing matrix. Therefore, there is an urgent need in the art for an improved heating component or system.

[0003] The methods described in this section are not necessarily methods that had been previously conceived or adopted. Unless otherwise specified, no method described in this section should be assumed to be prior art simply because it is included in this section. Similarly, unless otherwise specified, the issues mentioned in this section should not be considered to be accepted in any prior art. Summary of the Invention

[0004] According to a first aspect of this disclosure, a non-contact heating assembly for an atomizing device is provided. The non-contact heating assembly is used to atomize an atomizing matrix in the atomizing device to form an aerosol. The non-contact heating assembly includes: a body having a top wall, a bottom wall, and a side wall, the top wall, bottom wall, and side wall together defining a heating cavity inside the body; and a heating element disposed inside the heating cavity. The non-contact heating assembly is configured to heat air inside the heating cavity through the heating element, and the heated air is output from the non-contact heating assembly to heat the atomizing matrix.

[0005] According to a second aspect of this disclosure, an atomizing device is provided, comprising: an atomizing matrix storage component for storing an atomizing matrix; and a non-contact heating component according to a first aspect of this disclosure, the non-contact heating component for outputting heated air to atomize the atomizing matrix into an aerosol.

[0006] According to one or more embodiments of this disclosure, a non-contact heating method is achieved by heating the air inside the heating chamber and using the heated air to heat and atomize the atomizing matrix. This helps the atomizing matrix to gradually vaporize at a suitable temperature, thereby forming an aerosol with more uniform particle size and higher stability, improving the user experience of the atomizing device. Since the heating element is located in the internal heating chamber defined by the main body and does not directly contact the atomizing matrix, the non-contact heating assembly described in this disclosure can avoid the atomizing matrix from easily scorching due to localized high temperatures and also helps to avoid atomizing matrix residue on the surface of the heating element, thereby maintaining good thermal efficiency and service life of the heating element. At the same time, the heating method of this disclosure reduces the dependence on the shape and loading method of the atomizing matrix, improving the versatility of the non-contact heating assembly.

Detailed Implementation

[0010] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0011] Within the scope of this disclosure, "atomizing matrix" refers to a mixture or auxiliary substance that can be wholly or partially atomized into an aerosol by an electronic atomizing device or similar device. The atomizing matrix can be a liquid, paste, or solid form of e-cigarette material, medical drugs, skincare products, etc. By atomizing these media, an aerosol that can be inhaled or absorbed can be delivered to the user; "aerosol" refers to a colloidal dispersion system formed by the dispersion and suspension of solid or liquid particles in a gaseous medium; "atomizing device" refers to a device that forms an aerosol from a stored atomizable matrix, i.e., the atomizing matrix, through heating or ultrasound; "electronic cigarette" refers to an electronic atomizing device that generates an aerosol (i.e., smoke) from tobacco material, such as e-liquid or e-cream, as an atomizing matrix, through atomization for inhalation, sucking, chewing, or nasal inhalation.

[0012] Existing cigarette smoking devices suffer from problems such as scorching, uneven heating, and difficulty in controlling the heating temperature when heating the atomizing substrate. For example, hookah products typically rely on traditional charcoal combustion as a heat source. The high-temperature heat generated by charcoal combustion is conducted through the device's internal air passages to the atomizing substrate (such as tobacco paste, tobacco leaves, or a special tobacco blend), thereby achieving the atomization process. However, the temperature of charcoal combustion is highly dependent on external environmental variables (such as ambient humidity, ventilation intensity, charcoal density, and combustion stage), resulting in highly unstable heat output and difficulty in precise control. This not only affects atomization efficiency and flavor consistency but also easily produces harmful byproducts from incomplete atomization. In contrast, products such as e-cigarettes and heated tobacco products often use electric heating elements (such as nickel-chromium alloy coils, ceramic heating elements, or metal mesh) to directly heat the atomizing substrate (including e-liquid, compressed tobacco leaves, or tobacco paste) through physical contact. This direct-contact atomization matrix heating method is prone to forming hot spots in local areas, resulting in uneven matrix heating and easy scorching. In areas where there is no direct physical contact, insufficient heat conduction may lead to insufficient heating, resulting in problems such as incomplete atomization and large fluctuations in smoke volume.

[0013] In view of this, the present disclosure proposes a non-contact heating assembly for an atomizing device. The non-contact heating assembly is used to atomize an atomizing matrix in the atomizing device to form an aerosol. The non-contact heating assembly includes: a main body having a top wall, a bottom wall, and side walls, which together define a heating cavity inside the main body; and a heating element disposed inside the heating cavity. The non-contact heating assembly is configured to heat air within the heating cavity via the heating element, and the heated air is output from the non-contact heating assembly to heat the atomizing matrix. The heating element can be made of a resistance-heating metal or a conductive metal suitable for electromagnetic induction heating.

[0014] In some embodiments, the resistance heating metal may include at least one of the following materials: nickel-chromium alloy; iron-chromium-aluminum alloy; nickel-iron alloy; stainless steel (e.g., austenitic or ferritic stainless steel); constantan (copper-nickel alloy). These resistance heating metals typically possess high resistivity and good high-temperature resistance, making them suitable for stably generating Joule heat under energized conditions for heating air within a heating chamber. In some embodiments, the conductive metal suitable for electromagnetic induction heating may include at least one of the following materials: iron; iron-based alloy; stainless steel; nickel; nickel-based alloy. These conductive metals can generate induced current and eddy current losses under the action of an alternating electromagnetic field, thereby achieving rapid heating and making them suitable for electromagnetic induction heating.

[0015] The following reference Figures 1 to 5 The non-contact heating assembly of this disclosure is described in detail. Among them, Figure 1 A schematic diagram of a non-contact heating assembly according to an exemplary embodiment of the present disclosure is shown; Figure 2 It shows Figure 1 A cross-sectional view of the non-contact heating component in the image; Figure 3 It shows Figure 1 A cross-sectional view of the non-contact heating component from another angle; Figure 4 A schematic diagram of a U-shaped column of a non-contact heating assembly according to an exemplary embodiment of the present disclosure is shown; Figure 5 A schematic diagram of a heating element in a non-contact heating assembly according to an exemplary embodiment of the present disclosure is shown.

[0016] like Figures 1 to 3As shown, the non-contact heating assembly 10 includes a main body 11 and a heating element 12. The main body 11 has a top wall 101, a bottom wall 102, and a side wall 103, which together define a heating cavity 104 inside the main body 11. The heating element 12 is disposed inside the heating cavity 104, and the non-contact heating assembly 10 is configured to heat the air inside the heating cavity 104 via the heating element 12. The heated air is then output from the non-contact heating assembly 10 and used to heat the atomized matrix.

[0017] In the above embodiments, by heating the air inside the heating chamber 104 and using the heated air to heat and atomize the atomizing matrix, a non-contact heating method is achieved. This helps the atomizing matrix to gradually vaporize at a suitable temperature, thereby forming an aerosol with more uniform particle size and higher stability, improving the user experience of the atomizing device. Since the heating element 12 is located in the internal heating chamber 104 defined by the main body 11 and does not directly contact the atomizing matrix, the non-contact heating assembly 10 described in this disclosure can avoid the atomizing matrix from easily scorching due to local high temperatures and also helps to avoid residual atomizing matrix on the surface of the heating element 12, thereby maintaining the good thermal efficiency and service life of the heating element 12. At the same time, the heating method of this disclosure reduces the dependence on the shape and loading method of the atomizing matrix, improving the versatility of the non-contact heating assembly 10.

[0018] like Figure 1 The main body 11 of the non-contact heating assembly 10 described herein may have a generally cylindrical shape 13. However, it should be understood that the shape of the main body 11 of the non-contact heating assembly 10 described herein may also vary depending on the specific construction of the atomizing device. For example, in some examples, the main body 11 may have other suitable three-dimensional shapes such as a hexahedron.

[0019] In some embodiments, the top wall has a plurality of first air holes 1011, and the bottom wall has a plurality of second air holes 1021. It is understood that, depending on the specific structure of the atomizing device, the multiple holes on the top wall may be used as second air holes, and the multiple holes on the bottom wall as first air holes. For example... Figure 1 and Figure 2 As shown, when a user uses the non-contact heating assembly 10 for an atomizing device as described in this disclosure, external air can enter the heating chamber 104 from above the non-contact heating assembly 10, allowing the air heated by the heating element 12 to exit from below the heating chamber 104 to heat the atomizing matrix. The arrangement of the corresponding first air vents 1011 and second air vents 1021 creates a stable flow path for the air within the heating chamber 104, thereby improving the efficiency and uniformity of air heating and facilitating a stable output of hot air for non-contact atomization.

[0020] like Figure 2 As shown, in some examples, the thickness of the top wall can be slightly greater than that of the bottom wall so that the heated air can leave the heating chamber 104 more quickly. Furthermore, the difference in thickness helps to maintain sufficient air within the heating chamber 104, contributing to the stability and consistency of the non-contact heating assembly 10's operation.

[0021] In some embodiments, the non-contact heating assembly 10 further includes a plurality of pillars 13 disposed inside the heating cavity 104, and the heating element 12 is disposed in multiple layers around the heating cavity 104 and passes through the plurality of pillars 13.

[0022] In the above embodiments, such as Figure 5 As shown, the arrangement of multiple pillars 13 facilitates the formation of a multi-layered arrangement of heating elements 12 suspended within the heating chamber 104. In the prior art, heating elements 12 are typically attached or embedded over a large area on a support, which results in most of the heat from the heating element 12 being absorbed by the support, leading to slow heating and affecting heating efficiency. In contrast, the heating elements 12 of this application pass through the pillars 13, not tightly attached to them, but suspended within the main body. Almost the entire surface area of ​​the heating elements 12 is suspended, facilitating rapid heating and improving the response speed and user experience of the atomizing device. Furthermore, the suspension of the heating elements 12 also allows for larger gaps between them, facilitating the flow of hot air and improving overall heating efficiency. Preferably, the heating elements 12 are made in a filament shape and pass through the pillars 13, or they can be made in a mesh shape and fitted onto the pillars 13 through individual mesh openings, with most of the other heating elements 12 suspended. Furthermore, in the above arrangement, the heating element 12 can exchange heat with the multiple columns 13 and further heat the air in the heating chamber 104 through the multiple columns 13. This helps to make the air in the heating chamber 104 obtain more sufficient and uniform heat exchange, improves the overall temperature uniformity of the air in the heating chamber 104, and enhances the stability and consistency of the hot air output, thereby improving the non-contact heating atomization performance based on hot air.

[0023] In some examples, multiple pillars 13 may be arranged along the circumferential direction of the heating element 12. In some examples, multiple pillars 13 may be arranged symmetrically with respect to the geometric center of the body 11.

[0024] In some implementations, such as Figure 3 and Figure 4 As shown, each of the plurality of columns 13 has a U-shaped cross-sectional shape and each of the plurality of columns 13 has a plurality of through holes 131 arranged at intervals along its height direction, through which the heating element 12 passes.

[0025] In some embodiments, the heating element 12 can pass sequentially through a plurality of through holes 131 spaced apart along the height direction. In other embodiments, depending on the arrangement of the plurality of columns 13 and / or the structural arrangement of the heating element 12, the heating element 12 can also pass through at least one of the plurality of through holes 131 to suspend in the heating chamber 104. As mentioned above, the heating element 12 of this application is disposed on the column 13 but is not tightly attached to the column 13, but is suspended in the main body. Almost most of the area of ​​the heating element 12 is in a suspended state, which facilitates the rapid heating of the heating element 12, thereby improving the response speed and user experience of the atomizing device. In addition, the suspension of the heating element 12 also results in a larger gap between them, which facilitates the flow of hot air and improves the overall heating efficiency.

[0026] By arranging the multiple columns 13 into a U-shaped cross-section structure, not only are the columns 13 able to form open spaces while ensuring structural strength, which facilitates airflow within the heating chamber 104, but the contact area between the column 13 and the air within the heating chamber 104 is also increased, thereby enhancing heat exchange efficiency and further improving the air heating effect. Each column 13 can also have an O-shaped, M-shaped, or B-shaped cross-section, as long as there is space within each column 13 or between them. Furthermore, the through-holes 131 along the height direction of the multiple columns 13 allow the heating element 12 to be stably positioned at different heights, effectively preventing loosening or displacement of the heating element 12 and improving the stability and consistency of the overall structure. In some embodiments, each of the multiple columns 13 is made of a porous material.

[0027] In some embodiments, the body 11 (including the top wall, bottom wall and side wall 103) is made of a porous material.

[0028] The porous material has a pore structure (i.e., micropores, capillaries, etc.) configured to trap air. In some embodiments, the porous material includes one or more of ceramics, quartz, glass, silicon carbide, and diatomaceous earth. Porous materials have good heat-locking (thermal insulation) properties and, due to their air-trapping microporous structure, have a low thermal conductivity. Figures 1 to 3 As shown, the main body 11, made of porous material, can effectively reduce the amount of heat or the rate of heat transfer from the interior of the heating chamber 104 to the exterior of the non-contact heating component 10, thereby achieving the function of heat preservation and heat storage.

[0029] In some examples, the body 11 and pillars 13 can be manufactured by sintering. It is understood that the body 11 described in this disclosure can also be manufactured using porous materials in other suitable ways, and this disclosure does not limit this. In some examples, the porous material of the body 11 can be the same as the porous material of the plurality of pillars 13. In some examples, the porous material of the body 11 can also be different from the porous material of the plurality of pillars 13.

[0030] In some embodiments, the top wall 101 is detachably fixed to the side wall 103, and the side wall 103 and the bottom wall 102 are integrally formed. The integrally formed side wall 103 and bottom wall 102 help reduce manufacturing costs. Figure 2 As shown, the top wall may have an extension for abutting against the side wall 103. Furthermore, within the scope of this disclosure, the top wall may be detachably fixed to the side wall 103 by any suitable means, such as threaded connection or snap-fit ​​connection, and this disclosure does not impose any particular limitation. By providing a detachable top wall, the installation, replacement, or maintenance of internal components such as the heating element 12 and the column 13 is facilitated, which improves the assembly convenience and maintenance efficiency of the non-contact heating assembly 10 and extends its service life.

[0031] In some embodiments, the outer surface of the sidewall 103 is provided with a coating (not shown in the drawings for simplicity). In some examples, the coating may also be provided on the outer surfaces of the top and bottom walls.

[0032] In the above embodiments, by providing a coating on the outer surface of the sidewall 103, the thermal and surface stability of the sidewall 103 of the main body 11 can be improved, which helps to further reduce heat loss to the outside, concentrate heat in the heating cavity 104 inside the main body 11, and improve the reliability of the non-contact heating component 10 under high temperature working conditions.

[0033] In some embodiments, the coating on the outer surface of the sidewall 103 may include silicon dioxide and a black pigment. By providing a coating with a black pigment (e.g., copper chromium black), the thermal properties of the outer surface of the outer wall 103 can be improved, and compared with a structure without a coating, the non-contact heating assembly in this embodiment has less heat loss and higher heat utilization efficiency during operation, which is beneficial to improving the stability of the non-contact air heating process.

[0034] In some embodiments, the mass ratio of silica to black pigment can be 9:1, meaning the coating comprises 9 parts silica and 1 part black pigment. At this ratio, the coating achieves superior overall performance in terms of thermal radiation and insulation while maintaining good adhesion and structural stability. In other embodiments, the ratio of silica to black pigment can be adjusted within the range of 6–12:1. Preferably, the ratio is 8–10:1. A suitable ratio can be selected to achieve a balance between the thermal stability, mechanical stability, and thermal radiation characteristics of the coating, to meet the needs of different heating powers or operating environments.

[0035] The specific selection of the black pigment is not particularly limited in this disclosure. For example, in some embodiments, the black pigment may include, but is not limited to, the following: copper chromium black, iron chromium black, manganese iron black, and ferrite black pigments (e.g., iron oxide). In some other embodiments, the black pigment may also include titanium-based composite black pigments, zirconium-based composite black pigments, or silicon-containing composite inorganic black pigments.

[0036] In some embodiments, the sidewall 103 has a first opening 1031 and a second opening 1032. The non-contact heating assembly 10 further includes a first electrode connector 14 and a second electrode connector 15, which are used to electrically connect to the heating element 12 through the first opening 1031 and the second opening 1032, respectively. In the above embodiments, the heating element 12 can be electrically connected to an external power supply assembly or controller through the first electrode connector and the second electrode connector, thereby facilitating precise control of the heating power or heating temperature of the heating element 12.

[0037] exist Figure 1 In the example shown, the first opening 1031 and the second opening 1032 are positioned opposite each other. In other examples, depending on the arrangement of the heating element within the heating chamber, the first opening 1031 and the second opening 1032 may have other arrangements, such as being 90 degrees or 120 degrees apart. In some examples, depending on the construction of the atomizing device, the first opening 1031 and the second opening 1032 may also be located on the top or bottom wall.

[0038] According to a second aspect of this disclosure, an atomizing device is provided, comprising: an atomizing matrix storage component for storing an atomizing matrix; and a non-contact heating component 10 as described in the first aspect of this disclosure, the non-contact heating component 10 for outputting heated air to atomize the atomizing matrix into an aerosol.
