Description

Technical Field

[0001] This invention relates to the field of aerosol generation technology, specifically to a bubble detachment from a substrate, an atomizing component, and an atomizing device. Background Technology

[0002] The atomizer coil is the core component of an atomizing device, generating inhalable vapor or aerosol by heating an aerosol matrix. Common atomizer coils typically consist of a liquid guide and a heating element. The liquid guide draws in and conducts the aerosol matrix, which is then heated and atomized by the heating element on the other side. This liquid guide serves as both a conduction channel for the aerosol matrix and an air exchange channel, making it a crucial component for the atomizer coil's heating and atomization process. However, when the liquid guide uses micro-perforations, the heating element on the liquid guide can easily block some of these perforations, turning them into blind holes. During heating and atomization, tiny bubbles are generated on the surface of the liquid guide. Due to the high viscosity of the aerosol matrix, these bubbles may adhere to the liquid guide, affecting atomization and creating localized high-temperature points on the heating element, thus impacting the lifespan of the atomizer coil. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of the prior art by providing a method for bubble detachment from the substrate, which has the advantage of enabling the attached bubbles to detach quickly.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a bubble detachment from a substrate, comprising a conductive liquid for conducting an aerosol matrix, the conductive liquid having a conductive hole, one side of the conductive liquid being a heating surface with a heating element, the other side of the conductive liquid being a conductive surface, the conductive hole penetrating between the conductive surface and the heating surface, and the conductive surface having an inclination.

[0005] The present invention further provides that the cross-sectional shape of the liquid guiding surface is symmetrical along the central axis.

[0006] In a further embodiment of the present invention, the liquid guiding surface is a conical surface.

[0007] In a further embodiment of the present invention, the liquid guiding surface is an arc surface.

[0008] In a further embodiment of the present invention, the diameter of the liquid guiding hole ranges from 20 μm to 200 μm.

[0009] The present invention further provides that the spacing between the liquid guiding holes ranges from 20 μm to 200 μm.

[0010] The present invention further provides that the resistance of the heating element is in the range of 0.2Ω to 1.5Ω.

[0011] The present invention also relates to an atomizing component, including an atomizing core support, a bottom support, an oil reservoir, a conductive sheet, and a bubble detachment substrate as described above. The atomizing core support is disposed on the bottom support, the bubble detachment substrate is disposed on the atomizing core support, the conductive sheet is respectively connected to both sides of the heating element, and the oil reservoir is disposed on the bottom support.

[0012] The present invention further provides that the atomizing core support is provided with a mating inclined surface corresponding to the inclination of the liquid guiding surface.

[0013] The present invention also relates to an atomizing device, including a housing and an atomizing component as described above, the atomizing component being assembled at the bottom of the housing, and an air outlet of the housing having an air tube and a guide fluid, the guide fluid having an inwardly inclined surface for allowing condensate to flow back.

[0014] After adopting the above technical solution, the beneficial effects of the present invention are as follows: the liquid guide adopts a layout with the heating element facing upward, the heating element is set on the top side, and the bottom liquid guide surface is a bubble guiding slope with an inclined angle. The slope design can help the aerosol matrix bubbles to quickly detach from the liquid guide, avoid too many bubbles adhering to the bottom side of the liquid guide and blocking the liquid guide hole, affecting the liquid guide atomization, and achieve a good anti-dry burning effect.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.

[0025] This embodiment relates to a bubble detachment from a substrate, mainly comprising a conductive liquid 1 for conducting aerosol matrix, such as... Figure 1 and Figure 2 As shown. The liquid guide 1 has liquid guide holes 10 for guiding the liquid, specifically capillary micropores, which can use capillary force to absorb the aerosol matrix and conduct it to the other side. One side of the liquid guide 1 is a heating surface 1B with a heating element 2, and the other side is a liquid guide surface 1A with an inclination. The direction of the liquid guide holes 10 is from the side of the liquid guide surface 1A to the side of the heating surface 1B. In this embodiment, the liquid guide 1 adopts a layout with the heating element 2 facing upward. The aerosol matrix is ​​absorbed on the bottom side of the liquid guide surface 1A and then conducted to the top side of the liquid guide 1 at the heating element 2 for heating and atomization. The liquid guide surface 1A is an inclined bubble guiding slope with a large inclination angle, which helps the aerosol matrix bubbles to quickly detach from the liquid guide 1. Bubbles cannot be adsorbed on the liquid guide surface 1A, avoiding the problem of too many bubbles adhering to the bottom side of the liquid guide 1, which would affect the atomization and service life of the liquid guide.

[0026] The liquid guiding surface 1 is covered with micropores, but the heating element 2 processed on its surface partially covers the liquid guiding holes 10, resulting in blind holes. Therefore, during heating and atomization, microbubbles are generated on the liquid guiding surface 1A of the liquid guiding surface 1. Due to the high viscosity of the aerosol matrix, the bubbles adhere to the liquid guiding surface 1A of the liquid guiding surface 1 and cannot detach in time. The adhesion of bubbles severely affects the liquid guiding surface 1, and may cause local high-temperature points to be generated in the heating element 2 due to dry burning, thus affecting the service life. Setting the liquid guiding surface 1A as an inclined bubble guiding slope helps the bubbles to detach quickly from the liquid guiding surface 1A, which can avoid excessive bubbles adhering to it and thus avoid the occurrence of local high-temperature points.

[0027] The shape of the liquid guiding surface 1A is not limited, but the cross-sectional shape of the liquid guiding surface 1A is preferably symmetrical along the central axis to avoid uneven distribution of aerosol matrix bubbles, which would increase the difficulty of bubble detachment.

[0028] In the first embodiment, the liquid guiding surface 1A is specifically an arc-shaped surface, with the center of the liquid guiding surface 1 protruding more than the sides, forming an arc-shaped convex slope, such as... Figure 1 As shown. It can also be tilted to facilitate the rapid detachment of bubbles from the bottom of the guiding liquid 1.

[0029] In the second embodiment, the liquid guiding surface 1A is specifically a conical surface, sloping from both sides of the liquid guiding surface 1 towards the center, with the center presenting an obtuse angle, such as... Figure 2 As shown. The steeply sloping conical surface helps bubbles to quickly detach from the bottom of the liquid guide 1, and it is easy to match the overall shape of the atomizing component to form a consistent taper, making the structure more compact.

[0030] Specifically, the diameter of the liquid guiding holes 10 ranges from 20μm to 200μm. A large number of liquid guiding holes 10 are distributed across the liquid guiding surface 1. These holes are fabricated on the substrate using mechanical processing techniques such as laser processing and etching, and serve to conduct the aerosol matrix. The relatively small diameter of the liquid guiding holes 10 allows them to effectively utilize capillary force to lock in oil and guide the liquid. The liquid guiding holes 10 are micro-perforations; each suction operation generates tiny air bubbles on the bottom surface of the liquid guiding surface 1. The tilt angle of the liquid guiding surface 1A is required to facilitate the rapid detachment of these tiny air bubbles. The spacing between the liquid guiding holes 10 ranges from 20μm to 200μm, resulting in a large number of liquid guiding holes 10 distributed within the limited area of ​​the liquid guiding surface 1.

[0031] The material of the liquid conductor 1 is quartz glass. Specifically, in this embodiment, the liquid conductor 1 is a porous liquid conductor 1 made of quartz as the substrate. The top side of the liquid conductor 1 is processed with a heating element 2 using different processes such as screen printing, pad printing, and coating. The resistance of the heating element 2 is preferably between 0.2Ω and 1.5Ω.

[0032] This embodiment also relates to an atomizing component, such as... Figure 3 As shown, its structure mainly includes an atomizing core support 3, a bottom support 4, an oil reservoir 5, a conductive sheet 6, and a bubble detachment substrate as described above. The atomizing core support 3 is mounted on the bottom support 4, and the bubble detachment substrate is mounted on the atomizing core support 3. The conductive sheet 6 is connected to both sides of the heating element 2, and the oil reservoir 5 is mounted on the bottom support 4. The bottom support 4 has an air inlet, and its upper part supports the atomizing core support 3. The oil reservoir 5 is located below the atomizing core support 3, and the oil reservoir 5 has clearance holes corresponding to the air inlet for airflow. The atomizing core support 3 supports the conductive liquid 1, and the conductive part is used to make conductive connections with the electrodes. The heating surface 1B of the conductive liquid 1 faces upward and the conductive surface 1A faces downward. The heating part is located at the top of the conductive liquid 1 and receives the aerosol matrix conducted from the conductive liquid 1. When the conductive parts on both sides are energized, the heating part heats up, heating and atomizing the aerosol matrix in contact with the heating part into an aerosol, thus completing atomization.

[0033] The atomizing core support 3 is provided with a mating inclined surface 31 corresponding to the inclination of the liquid guiding surface 1A. For example... Figure 4 As shown, the bottom of the atomizer core support 3 mates with the liquid guiding surface 1A of the liquid guiding 1, forming a consistent shape. This helps the bubbles to detach from the liquid guiding surface 1A more quickly and effectively, thus preventing localized high temperatures in the liquid guiding 1. When the liquid guiding 1 adopts a conical surface design, the mating slope 31 at the bottom of the atomizer core support 3 has the same taper as the liquid guiding surface 1A. When the liquid guiding 1 adopts an arc surface design, the arc of the mating slope 31 at the bottom of the atomizer core support 3 is consistent with the arc of the liquid guiding surface 1A.

[0034] This embodiment also relates to an atomizing device, such as... Figure 6 As shown, the device includes a housing 7 and an atomizing assembly as described above, with the atomizing assembly mounted at the bottom of the housing 7. The housing 7 has an oil reservoir 70 and an air outlet 71, which communicates with the air inlet of the atomizing assembly, forming an air passage structure within the housing 7. The air outlet 71 of the housing 7 contains an air pipe 72 and a guide tube 73, as shown... Figure 4 and Figure 5 As shown, the liquid guide 1 has an inwardly inclined surface, which is used to allow the condensate adhering to the air outlet pipe 72 to flow back. The heating element 2 of the liquid guide 1 is arranged upward, so that the aerosol particles generated by heating and atomization can directly reach the air outlet 71, thereby achieving a more complete release. This prevents large aerosol particles from condensing on the airway wall due to the bends in the airway structure, which would otherwise affect the taste.

[0035] The working principle of this invention is roughly as follows: The liquid guide 1 has a liquid guide hole 10 for guiding the liquid. It uses capillary force to draw in the aerosol matrix and conduct it to the other side. One side of the liquid guide 1 is a heating surface 1B with a heating element 2, and the other side is a liquid guide surface 1A with an inclined angle. The aerosol matrix is ​​drawn in on the liquid guide surface 1A side of the liquid guide 1 and then conducted to the heating element 2 on the top side of the liquid guide 1 for heating and atomization. The liquid guide surface 1A is a bubble guiding slope with an inclined angle. The larger inclined angle helps the aerosol matrix bubbles to quickly detach from the liquid guide 1, avoiding the problem of too many bubbles adhering to the bottom side of the liquid guide 1, which would affect the atomization and service life of the liquid guide.

[0036] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
