Description

TECHNICAL FIELD

[0002] The atomization device (for example, a cartridge of an electronic cigarette) of the electronic cigarette in the related art is usually provided with an oil storage chamber and an atomization core. The tobacco tar in the oil storage chamber enters the atomization chamber through the atomization core and is heated and atomized into smoke (aerosol) by the atomization core. The smoke then passes through the air channel and the suction port and enters the user's oral cavity and nasal cavity. Different types of tobacco tar may form smoke with different particle sizes after being heated and atomized. For example, the aerosol that makes the oral cavity feel sweet has a relatively large particle size, and the aerosol that makes the nasal cavity feel fragrant has a relatively small particle size. The aerosol with a relatively large particle size is relatively heavy in quality and may sink in the air channel and not enter the user's oral cavity completely. Even when the suction force is small, the aerosol with a relatively large particle size may not easily come out of the atomization device, which affects the smoking experience. SUMMARY

[0035] In the description of the present application, the meaning of "a plurality of" is two or more.

[0036] An atomization device 1 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0037] As Figures 1-5As shown, the atomizing device 1 according to an embodiment of the present invention includes a housing 100, a first atomizing core 200, and a second atomizing core 300.

[0038] The housing 100 is provided with an air inlet 110, an air passage 120, a first oil reservoir 130, a first atomizing chamber 140, a second oil reservoir 150, and a second atomizing chamber 160. The air inlet 110 is connected to the first atomizing chamber 140 and the second atomizing chamber 160 through the air passage 120. A first atomizing core 200 is installed in the housing 100 and separates the first oil reservoir 130 and the first atomizing chamber 140. A second atomizing core 300 is installed in the housing 100 and separates the second oil reservoir 150 and the second atomizing chamber 160. In the extending direction of the air passage 120, the first atomizing chamber 140 is closer to the air inlet 110 than the second atomizing chamber 160.

[0039] According to an embodiment of the present invention, the atomizing device 1 includes an air inlet 110, an air passage 120, a first oil storage chamber 130, a first atomizing chamber 140, a second oil storage chamber 150, and a second atomizing chamber 160, provided in the housing 100. The e-liquid in the first oil storage chamber 130 and the e-liquid in the second oil storage chamber 130 may be different. For example, the e-liquid in the first oil storage chamber 130 may include flavor substances, which may be sweet or fruity, while the e-liquid in the second oil storage chamber 130 may include olfactory substances, which may be aromas. The e-liquid in the second oil storage chamber 130 may include one or more of the following substances: esters, alcohols, aldehydes, vanillin, maltol, furanones, and acids.

[0040] Furthermore, the first atomizing core 200 is installed on the housing 100 and separates the first oil storage chamber 130 and the first atomizing chamber 140. The second atomizing core 300 is installed on the housing 100 and separates the second oil storage chamber 150 and the second atomizing chamber 160. The first oil storage chamber 130 is connected to the first atomizing chamber 140 through the first atomizing core 200, and the second oil storage chamber 150 is connected to the second atomizing chamber 160 through the second atomizing core 300. The user inhales the vapor from the atomizing device 1 through the inhalation port 110.

[0041] Specifically, the e-liquid in the first oil reservoir 130 enters the first atomizer 200 through the side facing the first oil reservoir 130, and is atomized into vapor (aerosol) at the first atomizer 200, which then diffuses throughout the first atomizer chamber 140. Similarly, the e-liquid in the second oil reservoir 150 enters the second atomizer 300 through the side facing the second oil reservoir 150, and is atomized into vapor (aerosol) at the second atomizer 300, which then diffuses throughout the second atomizer chamber 160.

[0042] By separating the first oil storage chamber 130 and the second oil storage chamber 150, the e-liquid in the first oil storage chamber 130 and the e-liquid in the second oil storage chamber 150 will not mix with each other, thus avoiding mutual influence on the flavor between the e-liquid in the first oil storage chamber 130 and the e-liquid in the second oil storage chamber 150, and ensuring the purity of the e-liquid in the first oil storage chamber 130 and the e-liquid in the second oil storage chamber 150.

[0043] In other words, the e-liquid in the first reservoir 130 and the e-liquid in the second reservoir 150 will not be heated in the same location. This avoids chemical reactions when the e-liquid in the first reservoir 130 and the e-liquid in the second reservoir 150 are heated and atomized. Different types of e-liquid are atomized separately in different locations, which ensures that the resulting substances are purer and safer. It also prevents the production of toxic and harmful substances when different types of e-liquid are mixed and heated together. As a result, there is a wider selection of e-liquid types in the first reservoir 130 and the second reservoir 150. The atomizing device 1 can selectively use e-liquids with different flavor and aroma combinations to meet the needs of users with different habits. It is highly adaptable and helps to optimize the user experience.

[0044] Furthermore, in the extension direction of the airway 120, the first atomizing chamber 140 is closer to the inhalation port 110 than the second atomizing chamber 160. The vapor in the first atomizing chamber 140 may include large aerosol particles, while the vapor in the second atomizing chamber 160 may include small aerosol particles. Therefore, the large aerosol particles in the first atomizing chamber 140 have a short travel distance and are less likely to sink. Even when the user's inhalation airflow is weak, they can be easily inhaled simultaneously with the small aerosol particles, ensuring the taste quality of the vapor in the atomizing device 1. Moreover, there is a time difference between the vapor in the first atomizing chamber 140 and the vapor in the second atomizing chamber 160 entering the oral cavity, allowing the user to experience a more pronounced sense of layering, thus improving user satisfaction and overall experience.

[0045] Thus, the atomizing device 1 according to the embodiments of the present invention has advantages such as low probability of smoke sinking, obvious layering, and strong applicability.

[0046] In some embodiments of the present invention, such as Figures 1-5 As shown, in the extending direction of the air passage 120, the air inlet 110, the first oil reservoir 130, the first atomizing chamber 140, the second oil reservoir 150, and the second atomizing chamber 160 are arranged in sequence. In other words, the air inlet 110 and the second atomizing chamber 160 are located at both ends of the air passage 120, and the first atomizing chamber 140 is located between the air inlet 110 and the second atomizing chamber 160.

[0047] This design ensures a closer distance between the first atomizing chamber 140 and the inhalation port 110, allowing large aerosol particles in the first atomizing chamber 140 to enter the mouth through the inhalation port 110 with a shorter travel distance, reducing the likelihood of these particles sinking. Furthermore, when the user places the inhalation port 110 into their mouth, it is typically positioned at the top of the housing 100, with the first e-liquid reservoir 130 above the first atomizing chamber 140. E-liquid in the first e-liquid reservoir 130 can enter the first atomizing chamber 140 through the first atomizing coil 200. The second e-liquid reservoir 150 is positioned above the second atomizing chamber 160, allowing e-liquid in the second e-liquid reservoir 150 to enter the second atomizing chamber 160 under its own weight through the second atomizing coil 300.

[0048] Therefore, by arranging the air inlet 110, the first oil storage chamber 130, the first atomizing chamber 140, the second oil storage chamber 150, and the second atomizing chamber 160 sequentially along the extension direction of the airway 120, it is possible to satisfy the requirement that when the user puts the air inlet 110 into their mouth, the e-liquid in the first oil storage chamber 130 can flow into the first atomizing chamber 140 under its own gravity, and the e-liquid in the second oil storage chamber 150 can flow into the second atomizing chamber 160 under its own gravity.

[0049] In some embodiments of the present invention, such as Figure 1 and Figure 5 As shown, the first oil storage chamber 130 has a first oil outlet 131 on the side facing the first atomizing chamber 140, and the first atomizing core 200 is clamped and blocked by the chamber wall of the first oil storage chamber 130. The second oil storage chamber 150 has a second oil outlet 151 on the side facing the second atomizing chamber 160, and the second atomizing core 300 is clamped and blocked by the chamber wall of the second oil storage chamber 150.

[0050] By using the first atomizing core 200 to block the first oil outlet 131, it can be seen that the e-liquid in the first oil storage chamber 130 needs to be atomized into vapor (aerosol) by the first atomizing core 200 before it can diffuse into the first atomizing chamber 140. This prevents the e-liquid in the first oil storage chamber 130 from leaking directly into the first atomizing chamber 140 without being heated and atomized by the first atomizing core 200. Furthermore, since the first atomizing core 200 is clamped by the chamber wall of the first oil storage chamber 130, there is no need to set up a separate fixing structure for the first atomizing core 200, which simplifies the structure of the atomizing device 1 and makes disassembly and assembly more convenient.

[0051] Furthermore, by using the second atomizing core 300 to block the second oil outlet 151, it is known that the e-liquid in the second oil reservoir 150 needs to be atomized into vapor (aerosol) by the second atomizing core 300 before it can diffuse into the second atomizing chamber 160. This prevents the e-liquid in the second oil reservoir 150 from leaking directly into the second atomizing chamber 160 without being heated and atomized by the second atomizing core 300. Moreover, since the second atomizing core 300 is clamped by the wall of the second oil reservoir 150, there is no need to set up a separate fixing structure for the second atomizing core 300, which simplifies the structure of the atomizing device 1 and makes disassembly and assembly more convenient.

[0052] According to some specific embodiments of the present invention, such as Figure 3 As shown, the first atomizing chamber 140 has a first sidewall separating the first atomizing chamber 140 and the airway 120. The first sidewall has a first gap 141 for communicating with the first atomizing chamber 140 and the airway 120. By adjusting the size of the first gap 141, the amount of vapor (large aerosol particles) flowing from the first atomizing chamber 140 into the airway 120 can be controlled. On the one hand, this controls the amount of vapor entering the user's mouth from the airway 120, avoiding choking due to excessive vapor volume and ensuring comfort. On the other hand, it controls the ratio of large aerosol particles to small aerosol particles in the vapor entering the user's mouth, optimizing the user experience and improving comfort. In addition, the airflow within the airway 120 is more concentrated and flows more smoothly.

[0053] According to some specific embodiments of the present invention, such as Figure 4 As shown, the second atomizing chamber 160 has a second sidewall separating the second atomizing chamber 160 and the airway 120. The second sidewall has a second gap 161 for communicating with the second atomizing chamber 160 and the airway 120. By adjusting the size of the second gap 161, the amount of vapor (small aerosol particles) flowing from the second atomizing chamber 160 into the airway 120 can be controlled. On the one hand, this controls the amount of vapor entering the user's mouth from the airway 120, preventing choking due to excessive vapor volume and ensuring comfort. On the other hand, it controls the ratio of large aerosol particles to small aerosol particles in the vapor entering the user's mouth, optimizing the user experience and improving comfort. In addition, the airflow within the airway 120 is more concentrated and flows more smoothly.

[0054] In some embodiments of the present invention, such as Figure 2 As shown, the air inlet 110 includes a first air inlet 111 and a second air inlet 112, and the air passage 120 includes a first air passage 121 and a second air passage 122 that are not connected. The first air passage 121 is connected to the first atomizing chamber 140 and the first air inlet 111, respectively, and the second air passage 122 is connected to the second atomizing chamber 160 and the second air inlet 112, respectively. The first air passage 121 is shorter than the second air passage 122.

[0055] It should be noted that the type of e-liquid in the first e-liquid reservoir 130 is different from that in the second e-liquid reservoir 150. Therefore, the flavor of the vapor in the first atomizing chamber 140 is different from that in the second atomizing chamber 160. The vapor in the first atomizing chamber 140 enters the mouth through the shorter first airway 121, while the vapor in the second atomizing chamber 160 enters the mouth through the longer second airway 122. There is a time difference between the vapor in the first atomizing chamber 140 and the vapor in the second atomizing chamber 160 entering the mouth, so that when the user inhales the vapor from the atomizing device 1, they can more clearly feel the flavor layers, resulting in a better user experience.

[0056] Furthermore, before entering the user's mouth, the smoke in the first atomizing chamber 140 and the smoke in the second atomizing chamber 160 will never mix, preventing the smoke in the first atomizing chamber 140 and the smoke in the second atomizing chamber 160 from mixing prematurely. This ensures that the smoke in the first atomizing chamber 140 and the smoke in the second atomizing chamber 160 each have their own distinct flavor, further enhancing the sense of layering.

[0057] Specifically, such as Figures 1-5 As shown, the airway 120 is located at the center of the cross-section of the housing 100, and the inhalation port 110 is located at the center of the end face of the housing 100. This not only facilitates the connection between the airway 120 and the inhalation port 110, improving the smoothness of smoke flow, but also allows the smoke to diffuse more evenly when it enters the user's mouth from the inhalation port 110, fully contacting the user's mouth and nasal cavity, improving the taste and smell quality of the smoke, and satisfying the user's taste and smell needs.

[0058] According to some specific embodiments of the present invention, such as Figure 1 and Figure 5 As shown, the housing 100 includes an outer shell 410, a first inner shell 420, and a second inner shell 430. The outer shell 410, the first inner shell 420, and the second inner shell 430 can be integrally formed.

[0059] The outer shell 410 defines a receiving space 411 and an air intake 110. A first inner shell 420 is located within the receiving space 411 and connected to the outer shell 410. The first inner shell 420 and the outer shell 410 define a first oil reservoir 130. A second inner shell 430 is located within the receiving space 411 and connected to the outer shell 410. The second inner shell 430 and the outer shell 410 define a second oil reservoir 150. Both the first inner shell 420 and the second inner shell 430 are annular and spaced apart in the extending direction of the air passage 120. The inner walls of the first inner shell 420 and the second inner shell 430 respectively define a portion of the air passage 120.

[0060] For example, the first inner shell 420 and the outer shell 410 clamp the first atomizing core 200, meaning the first atomizing core 200 can be annular, with the inner wall of the first atomizing core 200 contacting the outer wall of the first inner shell 420, and the outer wall of the first atomizing core 200 contacting the inner wall of the outer shell 410. The second inner shell 430 and the outer shell 410 clamp the second atomizing core 300, meaning the second atomizing core 300 can be annular, with the inner wall of the second atomizing core 300 contacting the outer wall of the second inner shell 430, and the outer wall of the second atomizing core 300 contacting the inner wall of the outer shell 410.

[0061] This allows for convenient definition of the volume and position of the air intake 110, the first oil reservoir 130, and the second oil reservoir 150. The first atomizing chamber 140 is defined by the outer shell 410 and the first atomizing core 200 and is located between the first inner shell 420 and the second inner shell 430 in the extending direction of the air passage 120. The second atomizing chamber 160 is defined by the outer shell 410 and the second atomizing core 300 and is located on the side of the second inner shell 430 opposite to the first inner shell 420 in the extending direction of the air passage 120. Furthermore, it facilitates the air passage 120 passing through the first inner shell 420 to communicate with the first atomizing chamber 140 and passing through the second inner shell 430 to communicate with the second atomizing chamber 160, and it is advantageous to position the air passage 120 at the center of the housing 100.

[0062] Furthermore, such as Figure 3 As shown, the housing 100 also includes a third inner shell 440, which is located within the receiving space 411 and separates the first atomizing chamber 140 and the air passage 120. At least one of the first inner shell 420 and the second inner shell 430 has a first gap 141 with the third inner shell 440, and the first atomizing chamber 140 and the air passage 120 are connected through the first gap 141.

[0063] By setting the third inner shell 440, the communication area between the first atomizing chamber 140 and the airway 120 can be reduced. By adjusting the size of the first gap 141, the amount of vapor (large aerosol particles) flowing from the first atomizing chamber 140 into the airway 120 can be controlled. On the one hand, this controls the amount of vapor entering the user's mouth from the airway 120, preventing choking due to excessive vapor volume and ensuring comfort. On the other hand, it controls the ratio of large to small aerosol particles in the vapor entering the user's mouth, optimizing the user experience and improving comfort. In addition, the airflow within the airway 120 is more concentrated and flows more smoothly.

[0064] And, as Figure 4 As shown, the housing 100 also includes a fourth inner shell 450, which is located within the receiving space 411 and separates the second atomizing chamber 160 and the air passage 120. One of the second inner shell 430 and the outer shell 410 has a second gap 161 with the fourth inner shell 450, and the second atomizing chamber 160 and the air passage 120 are connected through the second gap 161.

[0065] By setting the fourth inner shell 450, the communication area between the second atomizing chamber 160 and the airway 120 can be reduced. By adjusting the size of the second gap 161, the amount of vapor (small aerosol particles) flowing from the second atomizing chamber 160 into the airway 120 can be controlled. On the one hand, this controls the amount of vapor entering the user's mouth from the airway 120, preventing choking due to excessive vapor volume and ensuring comfort. On the other hand, it controls the ratio of large to small aerosol particles in the vapor entering the user's mouth, optimizing the user experience and improving comfort. In addition, the airflow within the airway 120 is more concentrated and flows more smoothly.

[0066] Furthermore, such as Figure 3 As shown, the third inner shell 440 has a first gap 141 between it and the first inner shell 420, and is connected to the side of the second inner shell 430 facing the first inner shell 420. The third inner shell 440 and the second inner shell 430 can be integrally formed. In other words, the first gap 141 is located on the side of the first atomizing chamber 140 facing the air intake 110. Therefore, the distance between the first gap 141 and the air intake 110 is closer, which helps to shorten the flow path of the vapor in the first atomizing chamber 140, thus making the vapor from the first atomizing chamber 140 reach the air intake 110 faster. It also reduces the probability of the vapor from the first atomizing chamber 140 drifting along the air passage 120 towards the second atomizing chamber 160, thereby improving the effective utilization rate of the e-liquid.

[0067] And, as Figure 4 As shown, the fourth inner shell 450 has a second gap 161 with the outer shell 410 and is connected to the side of the second inner shell 430 facing away from the first inner shell 420. The fourth inner shell 450 and the second inner shell 430 can be integrally formed. In other words, the second gap 161 is located on the side of the second atomizing chamber 160 facing the air inlet 110. Therefore, the distance between the second gap 161 and the air inlet 110 is greater, which helps to extend the flow path of the vapor in the second atomizing chamber 160. This results in a longer time for the vapor from the second atomizing chamber 160 to reach the air inlet 110 compared to the time for the vapor from the first atomizing chamber 140 to reach the air inlet 110, effectively improving the flavor profile.

[0068] In some embodiments of the present invention, such as Figure 2As shown, the housing 100 also includes a fifth inner shell 460 and a sixth inner shell 470. The fifth inner shell 460 is connected to the first inner shell 420 and the second inner shell 430 respectively. The sixth inner shell 470 is connected to the second inner shell 430 and is arranged sequentially with the fifth inner shell 460 in the circumference of the airway 120. The sixth inner shell 470 extends to the air inlet 110 and divides the airway 120 into a first airway 121 and a second airway 122. The first atomizing chamber 140 is connected to the air inlet 110 through the first airway 121, and the second atomizing chamber 160 is connected to the air inlet 110 through the second airway 122.

[0069] For example, the fifth inner shell 460 extends circumferentially along the airway 120, and the fifth inner shell 460 is an open loop, that is, the fifth inner shell 460 is not connected at both ends of the airway 120 circumferentially. The sixth inner shell 470 is connected to the fifth inner shell 460 at both ends of the airway 120 circumferentially. In other words, the fifth inner shell 460 and the sixth inner shell 470 together form a closed loop in the circumferential direction of the airway 120.

[0070] The first airway 121 is directly connected to the first atomizing chamber 140, while the second airway 122 needs to pass through the second inner shell 430 to connect to the second atomizing chamber 160. This ensures that the distance between the first atomizing chamber 140 and the air inlet 110 is shorter than the distance between the second atomizing chamber 160 and the air inlet 110. As a result, the smoke in the first atomizing chamber 140 can flow into the air inlet 110 more quickly. There is a time difference between the smoke in the first atomizing chamber 140 and the smoke in the second atomizing chamber 160 entering the mouth, so that when the user inhales the smoke from the atomizing device 1, they can clearly feel the flavor layers, thus optimizing the user experience.
