Description

Technical Field

[0001] The present invention relates to the technical field of atomization, and particularly to an atomization structure, an atomization control method, and an electronic atomizer. Background Art

[0002] There are a wide variety of types of electronic atomization devices on the existing market, which are applied to fields such as medical devices, smoking devices, industrial machinery, etc. Taking the electronic atomizer, which is well-known to the public among atomization devices, as an example, an electronic atomizer generally consists of components such as an atomization chamber, a cartridge, and an atomization component. The atomization component of the electronic atomizer heats and atomizes the e-liquid provided by the cartridge to form a smoke for the user to inhale. During the heating process, after the e-liquid enters the atomization chamber, it is heated and atomized by the atomization component.

[0003] However, in the existing electronic atomizers, when the e-liquid is about to run out, due to insufficient e-liquid entering the atomization chamber, the ambient temperature in the entire atomization chamber rises, resulting in too high a temperature of the atomization component itself. And too high a temperature of the atomization component itself easily causes the atomization component to be damaged and reduces the atomization ability of the atomization component or directly causes the atomization component to be damaged, seriously affecting the service life of the device. In addition, the atomization efficiency of the existing electronic atomizers is low. When the user uses the electronic atomizer, the electronic atomizer cannot quickly heat and atomize the e-liquid to form a smoke, resulting in a certain waiting time required for the user at the initial use, seriously affecting the user experience.

[0004] Therefore, there is an urgent need for an atomization structure, an atomization control method, and an electronic atomizer to overcome the above defects. Summary of the Invention

[0005] The purpose of the present invention is to provide an atomization structure, an atomization control method, and an electronic atomizer. On the one hand, by monitoring the surface temperature of the first heating unit and reducing the heating power of at least one second heating unit when the surface temperature of the first heating unit reaches a first preset temperature, it effectively avoids that when the atomization liquid in the atomization chamber is about to run out, the first heating unit causes the atomization component to be damaged and reduces the atomization ability or directly causes the atomization component to be damaged due to too high a surface temperature, greatly improving the service life of the device; on the other hand, by setting multiple heating units to quickly heat and atomize the e-liquid to form a smoke, it greatly improves the atomization efficiency, thereby effectively reducing the waiting time for the user at the initial use and greatly improving the user experience.

[0027] To illustrate in detail the possible application scenarios, technical principles, specific implementable solutions, achievable objectives and effects of this application, the following will be described in detail with reference to the specific examples listed and in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of this application, and therefore are only used as examples and cannot be used to limit the protection scope of this application.

[0028] Please refer to Figure 1 , the atomization structure of the present invention can be applied to an electronic atomizer. Of course, according to actual application requirements, the atomization structure and atomization control method of the present invention can also be applied in other fields such as medical devices and industrial machinery. The present invention does not specifically limit the actual application scenarios of this atomization structure and atomization control method.

[0029] Please refer to Figure 1 and Figure 2 , the electronic atomizer of this embodiment includes an atomization structure, and this atomization structure includes an atomization part 10, an atomization component 20 and a control unit 30. The atomization part 10 is provided with an atomization chamber 11, and the atomization component 20 is placed in the atomization chamber 11. The atomization component 20 is used to heat and atomize the atomization liquid entering the atomization chamber 11. Specifically, the atomization chamber 11 of this embodiment can be arranged in a cylindrical or cubic shape, and the atomization chamber 11 has a certain internal space for the atomization component 20 to heat and atomize the atomization liquid.

[0030] Taking the electronic atomizer as an example, the atomization liquid here is specifically e-liquid. The e-liquid can be directly injected into the atomization chamber 11 through an injection hole, or can be connected to the atomization chamber 11 and the storage chamber storing the e-liquid through materials such as a cotton core. The e-liquid seeps into the cotton core, and thus the e-liquid is transferred from the storage chamber to the atomization chamber 11 through the cotton core.

[0031] For the method of transferring the e-liquid from the storage chamber to the atomization chamber 11 through the cotton core, specifically, the atomization part 10 at this time is also provided with a storage chamber. The storage chamber and the atomization chamber 11 are separated by a partition wall. The partition wall between the storage chamber and the atomization chamber 11 can be provided with a communication hole only for the cotton core to pass through. The cotton core penetrates into the communication hole, and one end is immersed in the e-liquid, and the other end extends into the atomization chamber 11. The entire cotton core soaked with e-liquid has e-liquid, so as to realize the transfer of the e-liquid from the storage chamber to the atomization chamber 11.

[0032] Of course, in other embodiments, the transfer of the e-liquid from the storage chamber to the atomization chamber 11 can also be realized by setting a suction device. Specifically, the suction device quantitatively sucks the e-liquid in the storage chamber and inputs the sucked e-liquid into the atomization chamber 11 by means such as spraying and injection, so as to complete the operation of transferring the e-liquid from the storage chamber to the atomization chamber 11.

[0033] It should be noted that the transfer of e-liquid from the storage chamber to the atomization chamber 11 can be designed according to actual needs, so the specific manner and specific structure of the e-liquid entering the atomization chamber 11 are not limited herein.

[0034] In addition, the atomization structure of this embodiment can be applied to common electronic atomizers on the market. By simply modifying common electronic atomizers on the market, the atomization structure of the present invention can be satisfied, which has a broad market prospect. Moreover, the specific working manner and specific structure of the electronic atomizer are not the main creative points of the present invention, and the specific working manner and specific structure of the electronic atomizer will not be elaborated in detail herein.

[0035] Please refer to Figure 1 and Figure 2 , the atomization component 20 of this embodiment includes a first heating unit 21 and two second heating units 22. The control unit 30 is electrically connected to the atomization component 20. The control unit 30 can independently control the heating power of the first heating unit 21 and each second heating unit 22, and when the surface temperature of the first heating unit 21 reaches the first preset temperature, reduce the heating power of at least one second heating unit 22.

[0036] Specifically, the first heating unit 21 of this embodiment is a stainless steel sheet, and the second heating unit 22 is a heating wire or a heating mesh sheet. Here, the second heating unit 22 is preferably set as a heating mesh sheet. The heating mesh sheet has more effective heating parts compared with the heating wire and can obtain better heating and atomization ability. The first heating unit 21 and the two second heating units 22 are arranged at intervals from top to bottom. Since the atomization chamber 11 of this embodiment is arranged in a cylindrical or cubic shape, in order to obtain a better atomization effect, the first heating unit 21 and the two second heating units 22 are arranged along the length direction of the atomization chamber 11 to ensure that the e-liquid in each section of the length direction of the atomization chamber 11 can be effectively heated and atomized.

[0037] In addition, the sizes of the stainless steel sheet and the heating wire / heating mesh sheet need to be set according to the cross-sectional area of the atomization chamber 11 along the length direction, so as to avoid blocking the atomization chamber 11 due to the too large sizes of the stainless steel sheet and the heating wire / heating mesh sheet, or avoid being unable to fully heat and atomize the e-liquid in the atomization chamber 11 due to the too small sizes of the stainless steel sheet and the heating wire / heating mesh sheet.

[0038] It should be noted that the first preset temperature of this embodiment is between 250°C and 300°C. Of course, the specific type of e-liquid, the specific size of the stainless steel sheet, and the space size of the atomization chamber 11 are also influencing factors of the first preset temperature. Therefore, in actual operation, the first preset temperature needs to be set according to the actual environment and is not limited herein.

[0039] In fact, the stainless steel sheet needs to have a relatively thin thickness to avoid occupying too much space in the atomization chamber 11. Moreover, the relatively thin stainless steel sheet is more sensitive to environmental temperature changes than the heating wire / heater mesh, and is suitable for effectively evaluating whether the e-liquid is about to run out by monitoring the surface temperature of the stainless steel sheet.

[0040] It can be understood that the control unit 30 can independently control the heating power of the first heating unit 21 and each second heating unit 22. It should be understood that the control unit 30 can linearly adjust or segmentally adjust the heating power of each heating unit independently. The control unit 30 can adjust the heating power of any heating unit to a certain value, such as a value higher or lower than a preset value. Of course, the control unit 30 can also adjust the heating power of any heating unit to zero. At this time, the heating unit with the heating power adjusted to zero is in a state of stopping heating. Generally, the control unit 30 is placed outside the atomization chamber 11 to avoid the influence of high temperature on the control unit 30.

[0041] In actual use, generally when the electronic atomizer is initially started, the control unit 30 will simultaneously adjust the heating power of all heating units to the corresponding preset values to quickly heat and atomize the e-liquid for the user to use. That is, when the electronic atomizer is initially started, the electronic atomizer of this embodiment has three heating sources. When the e-liquid is about to run out, the environmental temperature in the atomization chamber 11 will rise. Since the heating power of all heating units remains unchanged at this time, the surface temperature of each heating unit will rise. Since the relatively thin stainless steel sheet is more sensitive to environmental temperature changes than the heating wire / heater mesh, in this embodiment, it is determined whether the e-liquid is about to run out by monitoring the surface temperature of the first heating unit 21 to determine whether the environmental temperature in the atomization chamber 11 has risen, so as to determine whether the e-liquid is about to run out. Specifically, when the surface temperature of the first heating unit 21 reaches the first preset temperature, the control unit 30 reduces the heating power of at least one second heating unit 22, thereby reducing the environmental temperature in the atomization chamber 11 by reducing the heating source.

[0042] The setting of the first preset temperature needs to be set according to the actual situation. Specifically, it can be based on the temperature that the surface of the first heating unit 21 will reach when all heating units are working simultaneously at the preset values when the e-liquid is about to run out in the atomization chamber 11 as the first preset temperature.

[0043] Preferably, the atomization assembly 20 of this embodiment further includes a temperature acquisition unit 23. The temperature acquisition unit 23 is used to monitor the surface temperature of the first heating unit 21 in real time and feedback the surface temperature of the first heating unit 21 to the control unit 30. Specifically, the temperature acquisition unit 23 of this embodiment is specifically a temperature sensor, and its temperature acquisition probe contacts the surface of the first heating unit 21 to acquire the surface temperature of the first heating unit 21 in real time and feedback it to the control unit 30 through a circuit. The control unit 30 processes and judges the feedback value to determine whether the surface temperature of the first heating unit 21 reaches the first preset temperature, and when the surface temperature of the first heating unit 21 reaches the first preset temperature, the following operations are performed.

[0044] Specifically, in a specific atomization control method of this embodiment, when the surface temperature of the first heating unit 21 reaches the first preset temperature, the control unit 30 controls the heating power of one of the two second heating units 22 to be reduced to zero. For example, the heating power of the second heating unit 22 closer to the first heating unit 21 is reduced to zero, that is, the second heating unit 22 closer to the first heating unit 21 stops heating. At this time, in the atomization chamber 11, the original simultaneous heating by the first heating unit 21 and the two second heating units 22 becomes simultaneous heating by only the first heating unit 21 and one second heating unit 22. At this time, the number of heating sources in the atomization chamber 11 becomes two, and the ambient temperature in the atomization chamber 11 decreases, thereby reducing the surface temperature of the first heating unit 21 and avoiding dry burning of the atomization assembly 20 due to exhaustion of the e-liquid.

[0045] Of course, the control unit 30 can also control the other second heating unit 22 to stop heating. Specifically, the heating power of the second heating unit 22 far from the first heating unit 21 is reduced to zero, that is, the second heating unit 22 far from the first heating unit 21 stops heating. At this time, in the atomization chamber 11, the original simultaneous heating by the first heating unit 21 and the two second heating units 22 becomes simultaneous heating by only the first heating unit 21 and one second heating unit 22. At this time, the number of heating sources in the atomization chamber 11 becomes two, and the ambient temperature in the atomization chamber 11 decreases, thereby reducing the surface temperature of the first heating unit 21 and avoiding dry burning of the atomization assembly 20 due to exhaustion of the e-liquid.

[0046] In another specific implementation manner of this embodiment, when the surface temperature of the first heating unit 21 reaches the first preset temperature, the control unit 30 controls the heating power of both second heating units 22 to be reduced to zero, that is, both second heating units 22 in the atomization chamber 11 stop heating. At this time, the atomization chamber 11 is heated by the original first heating unit 21 and both second heating units 22 simultaneously, and it becomes heated only by the first heating unit 21. At this time, the number of heat sources in the atomization chamber 11 becomes one, and the ambient temperature in the atomization chamber 11 drops faster, so that the surface temperature of the first heating unit 21 drops faster, avoiding dry burning of the atomization assembly 20 due to exhaustion of the e-liquid.

[0047] Further, for the above two specific implementation manners, when the surface temperature of the first heating unit 21 reaches the first preset temperature and the duration exceeds the first preset time (such as 5 seconds, 10 seconds, 15 seconds, 1 minute, etc.), the control unit 30 reduces the heating power of the first heating unit 21. It can be understood that since the method of turning off one or both second heating units 22 through the above two specific implementation manners still cannot effectively reduce the surface temperature of the first heating unit 21, it can be considered at this time that the e-liquid is about to burn out or has already burned out. At this time, the control unit 30 can gradually reduce the heating power of the first heating unit 21 until the first heating unit 21 stops heating, avoiding damage to the atomization assembly 20 caused by long-term dry burning. The logic of gradually reducing the heating power of the first heating unit 21 needs to be set according to actual requirements and will not be elaborated here. After the first heating unit 21 stops heating, the second heating unit 22 that is still heating should also stop heating, which will not be elaborated here.

[0048] It should be noted that this embodiment is described by taking two second heating units 22 as an example. In fact, the number of second heating units 22 in this embodiment can also be one, three, four, etc. The specific atomization control method can be adaptively adjusted according to the above description and will not be elaborated here. In fact, in order to obtain a better atomization effect, the first heating unit 21 is generally close to the smoke outlet. Of course, the position setting manner of the first heating unit 21 and all second heating units 22 can be adjusted according to actual situations. For example, the first heating unit 21 is located between two adjacent second heating units 22. The position setting manner of the first heating unit 21 and all second heating units 22 will not be limited here.

[0049] Please refer to Figure 3 , the present invention of this embodiment also provides an atomization control method, which is applied to the atomization structure as above. The atomization control method includes the following steps:

[0050] S1. Start the atomization assembly 20, and the first heating unit 21 and all second heating units 22 of the atomization assembly 20 jointly heat and atomize the atomization liquid entering the atomization chamber 11;

[0051] S2. When the surface temperature of the first heating unit 21 reaches the first preset temperature, the control unit 30 reduces the heating power of at least one second heating unit 22.

[0052] Combined with Figure 1 - Figure 3 , on the one hand, the present invention monitors the surface temperature of the first heating unit 21, and when the surface temperature of the first heating unit 21 reaches the first preset temperature, reduces the heating power of at least one second heating unit 22, effectively avoiding that when the atomizing liquid in the atomizing chamber 11 is about to be exhausted, the atomizing ability of the atomizing component 20 is reduced or the atomizing component 20 is directly damaged due to the too high surface temperature of the first heating unit 21, greatly improving the service life of the device; on the other hand, the present invention sets a plurality of heating units, and the control unit 30 independently controls the heating power of each heating unit, so that the plurality of heating units of the present invention work simultaneously, can quickly heat and atomize the e-liquid to form smoke, greatly improving the atomizing efficiency, thereby effectively reducing the waiting time when the user uses it for the first time and greatly improving the user experience.

[0053] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
