However, due to its high viscosity and low fluidity, the e-liquid in the oil chamber has difficulty in ventilation, especially when the e-liquid in the oil chamber gradually decreases, the negative pressure in the oil chamber increases, which makes it difficult for the e-liquid in the oil chamber to flow and the oil supply is slow. At present, adding ventilation channels is often used to improve the problem of difficult ventilation of the e-liquid. However, high-viscosity e-liquid has poor fluidity. When ventilation is carried out through the ventilation channel, the ventilation channel may be blocked by the e-liquid, which eventually leads to ventilation difficulties, causing the heating element to burn and dry burn due to insufficient oil supply, affecting the user's smoking experience.

DETAILED DESCRIPTION
[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0038] For high-viscosity e-liquid, the problem of difficult e-liquid ventilation is usually solved by adding ventilation channels. However, high-viscosity e-liquid has poor fluidity. When ventilation is carried out through the ventilation channels, there is a situation where the ventilation channels are blocked by the e-liquid, which eventually leads to ventilation difficulties, causing the heating element to burn and dry burn due to insufficient oil supply, affecting the user's smoking experience.
[0039] Based on this problem, the inventor of the present application invented an aerosol generating device and specially designed the structure of the atomization structure. An additional ventilation oil chamber is added to cooperate with the ventilation channel for ventilation. Low-viscosity tobacco oil is added to the ventilation oil chamber to achieve ventilation and reduce the blockage of the ventilation channel. The ventilation oil chamber then provides air pressure to the main oil chamber to promote the fluidity of the tobacco oil in the main oil chamber.
[0040] See also Figure 1 and Figure 2 The embodiment of the present application provides an aerosol generating device, including an atomizing structure 1000, a battery structure 2000 and a nozzle 3000; the battery structure 2000 is electrically connected to the atomizing structure 1000, and the battery structure 2000 is used to power the atomizing structure 1000; the atomizing structure 1000 is used to atomize the tobacco oil into aerosol particles; the nozzle 3000 is connected to the atomizing structure 1000 and is used to transport the aerosol particles generated by the atomizing structure 1000 to the oral cavity of the smoker.
[0041] See also Figures 3 to 7 In one embodiment, the atomization structure 1000 is formed with a main oil chamber 160 and a ventilation oil chamber 190; one end of the ventilation oil chamber 190 is connected to the main oil chamber 160; the other end of the ventilation oil chamber 190 is connected to the external atmosphere; a ventilation element 150 is provided between the ventilation oil chamber 190 and the main oil chamber 160; the ventilation element 150 can prevent the liquid in the main oil chamber 160 from entering the ventilation oil chamber 190; the ventilation element 150 can allow the gas in the ventilation oil chamber 190 to enter the main oil chamber 160; the main oil chamber 160 stores an atomizing medium; the ventilation oil chamber 190 stores a ventilation medium; the viscosity of the ventilation medium is less than or equal to the viscosity of the atomizing medium.
[0042] The atomization structure 1000 provided in the embodiment of the present application is formed with a ventilation oil chamber 190, which is connected to the external atmosphere and contains a ventilation medium. When the user draws suction from the suction nozzle 3000, a portion of the external airflow will enter the ventilation oil chamber 190 to achieve ventilation in the ventilation oil chamber 190, so that the air pressure in the ventilation oil chamber 190 is balanced with the external air pressure. Since the gas in the ventilation oil chamber 190 can enter the main oil chamber 160, the air flow in the ventilation oil chamber 190 can be transported to the main oil chamber 160 to improve the fluidity of the atomization medium in the main oil chamber 160. At the same time, since the liquid in the main oil chamber 160 cannot enter the ventilation oil chamber 190, the atomized medium in the main oil chamber 160 will not flow into the ventilation oil chamber 190 and block the ventilation channel 180; in addition, the viscosity of the ventilation medium is less than or equal to the viscosity of the atomized medium, thereby reducing the situation where the ventilation channel 180 is blocked by the ventilation medium, thereby making the ventilation of the main oil chamber 160 smooth.
[0043] In one embodiment, the atomization structure 1000 is further formed with a ventilation channel 180 and an atomization chamber 170; the air inlet end of the ventilation channel 180 is connected to the atomization chamber 170; the air outlet end of the ventilation channel 180 is connected to the ventilation oil chamber 190. The external atmosphere enters the ventilation channel 180 through the atomization chamber 170, and then enters the ventilation oil chamber 190 from the ventilation channel 180 to achieve ventilation. It can be understood that in other embodiments of the present application, the air inlet end of the ventilation channel 180 can also be directly connected to the external atmosphere.
[0044] In one embodiment, one end of the atomizing chamber 170 is connected to the mouthpiece 3000, and the other end of the atomizing chamber 170 is connected to the external airflow. The tobacco oil in the main oil chamber 160 is atomized in the atomizing chamber 170 to form aerosol particles, and is guided to the mouthpiece 3000 through the atomizing chamber 170.
[0045] In one embodiment, the atomizing medium may be high-viscosity smoke oil, medium-viscosity smoke oil, and low-viscosity smoke oil. It should be noted that, according to the different solubility of the smoke oil, the smoke oil can be divided into high-viscosity smoke oil, medium-viscosity smoke oil, and low-viscosity smoke oil. Among them, high-viscosity smoke oil refers to smoke oil with a viscosity greater than 20,000 Pa·S; low-viscosity smoke oil refers to smoke oil with a viscosity lower than 10,000 Pa·S; medium-viscosity smoke oil is between high-viscosity smoke oil and low-viscosity smoke oil. In this embodiment, the atomizing medium in the main oil chamber 160 may be high-viscosity smoke oil, medium-viscosity smoke oil, or low-viscosity smoke oil, which has a wide range of applications. There is no need to design a ventilation structure separately for smoke oils of different viscosities, and there is no need to repeatedly adjust the structure and verify the feasibility, which reduces the research and development cycle and cost. Of course, in the present application, the atomizing structure 1000 is mainly suitable for the case where the atomizing medium is high-viscosity smoke oil, so that the value of the ventilation oil chamber 190 can be better reflected.
[0046] In one embodiment, the ventilation medium may be low-viscosity tobacco oil or other low-viscosity medium. In some special cases, the ventilation medium may also be medium-viscosity tobacco oil. Since the occurrence of the phenomenon of the ventilation medium blocking the ventilation channel 180 is related to the viscosity of the ventilation medium and the inner diameter of the ventilation channel 180, when the viscosity of the ventilation medium is selected, when the inner diameter of the ventilation channel 180 is large, the ventilation medium will flow into the ventilation channel 180 and cause oil leakage and blockage; when the inner diameter of the ventilation channel 180 is small, ventilation cannot be achieved. When designing, the inner diameter of the ventilation channel 180 can be designed according to the viscosity of the ventilation medium to minimize the situation where the ventilation medium blocks the ventilation channel 180. Since low-viscosity tobacco oil can be stored in the ventilation oil chamber 190, the low-viscosity tobacco oil rarely blocks the ventilation channel 180, thereby making the ventilation of the main oil chamber 160 smooth.
[0047] In one embodiment, the ventilation component 150 can allow gas to pass through and can prevent liquid from passing through. When ventilation is performed, the external airflow in the ventilation oil chamber 190 can enter the main oil chamber 160 to ensure smooth ventilation of the main oil chamber 160. The high-viscosity tobacco oil in the main oil chamber 160 cannot be carried by the gas to flow into the ventilation oil chamber 190, so that the high-viscosity tobacco oil in the main oil chamber 160 will not flow into the ventilation oil chamber 190 and block the ventilation channel 180. In addition, the low-viscosity tobacco oil in the ventilation oil chamber 190 can be prevented from being carried by the airflow to flow into the main oil chamber 160, thereby preventing the low-viscosity tobacco oil from entering the main oil chamber 160, causing the high-viscosity tobacco oil in the main oil chamber 160 to be impure and affecting the smoking taste.
[0048] In one embodiment, see Figure 8The ventilation element 150 is a waterproof breathable membrane 150a disposed between the ventilation oil chamber 190 and the main oil chamber 160. The waterproof breathable membrane 150a is a new type of polymer waterproof material. In the state of water vapor, the water particles are very small. According to the principle of capillary motion, they can smoothly penetrate into the capillary to the other side, thus causing the phenomenon of vapor permeability. When the water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (the water molecules "pull and counteract" each other), the water molecules cannot smoothly break away from the water droplets and penetrate to the other side, that is, water penetration is prevented, so that the breathable membrane has a waterproof function.
[0049] In the embodiment of the present application, a waterproof breathable membrane 150a is provided at the outlet of the ventilation oil chamber 190, so that during ventilation, gas exchange can be performed between the ventilation oil chamber 190 and the main oil chamber 160, and the external airflow in the ventilation oil chamber 190 can enter the main oil chamber 160 to ensure smooth ventilation of the main oil chamber 160. The high-viscosity tobacco oil in the main oil chamber 160 cannot be carried by the gas to flow into the ventilation oil chamber 190, so that the high-viscosity tobacco oil in the main oil chamber 160 will not flow into the ventilation oil chamber 190 and block the ventilation channel 180. In addition, the low-viscosity tobacco oil in the ventilation oil chamber 190 can be prevented from being carried by the airflow to flow into the main oil chamber 160, thereby preventing the low-viscosity tobacco oil from entering the main oil chamber 160, causing the high-viscosity tobacco oil in the main oil chamber 160 to be impure and affecting the smoking taste. It can be understood that in other embodiments of the present application, the above-mentioned ventilation component 150 can also be other structures that can allow gas to flow but cannot allow liquid to flow, and this is not the only limitation here.
[0050] In another embodiment of the present application, see Fig. 9 and Fig.10 The ventilation member 150 is a one-way valve 150b disposed between the ventilation oil chamber 190 and the main oil chamber 160; the one-way valve 150b can allow the gas in the ventilation oil chamber 190 to enter the main oil chamber 160; the one-way valve 150b can prevent the gas in the main oil chamber 160 from entering the ventilation oil chamber 190. When used for the suction nozzle 3000, the ventilation oil chamber 190 is ventilated through the ventilation channel 180. The gas in the ventilation oil chamber 190 can enter the main oil chamber 160 to improve the fluidity of the smoke oil in the main oil chamber 160 and reduce the occurrence of dry burning of the heating element 200. The gas in the main oil chamber 160 cannot enter the ventilation oil chamber 190, that is, ventilation cannot be achieved between the main oil chamber 160 and the ventilation oil chamber 190, and the high-viscosity smoke oil in the main oil chamber 160 will not be carried by the gas into the ventilation oil chamber 190 due to ventilation, thereby preventing the high-viscosity smoke oil in the main oil chamber 160 from entering the ventilation channel 180 through the ventilation oil chamber 190 and blocking the ventilation channel 180.
[0051] In another embodiment of the present application, see Fig. 9 and Fig.10When the ventilation member 150 is a one-way valve 150b, the one-way valve 150b allows the gas in the ventilation oil chamber 190 to enter the main oil chamber 160 when the air pressure difference between the main oil chamber 160 and the ventilation oil chamber 190 reaches a preset value. That is, the one-way valve 150b is in a closed state under normal conditions, and the main oil chamber 160 and the ventilation oil chamber 190 are not connected. When the user sucks the nozzle 3000, the ventilation oil chamber 190 is ventilated through the ventilation channel 180, so that the air pressure in the ventilation channel 180 is balanced with the external atmospheric pressure. When the high-viscosity smoke oil in the main oil chamber 160 gradually decreases, the negative pressure in the main oil chamber 160 gradually increases, and the air pressure value between the main oil chamber 160 and the ventilation oil chamber 190 reaches a preset value, the one-way valve 150b opens, and the one-way valve 150b allows the gas in the ventilation oil chamber 190 to enter the main oil chamber 160, so as to improve the fluidity of the smoke oil in the main oil chamber 160 and reduce the occurrence of dry burning of the heating element 200; and the gas in the main oil chamber 160 cannot enter the ventilation oil chamber 190, and ventilation cannot be achieved between the main oil chamber 160 and the ventilation oil chamber 190, and the smoke oil in the main oil chamber 160 will not be carried into the ventilation oil chamber 190 due to ventilation, thereby preventing the smoke oil in the main oil chamber 160 from entering the ventilation channel 180 through the ventilation oil chamber 190 and blocking the ventilation channel 180.
[0052] It should be noted that the air pressure difference between the main oil chamber 160 and the ventilation oil chamber 190 reaches a preset value, and this preset value can be set according to the fluidity of the smoke oil in the main oil chamber 160. For example, if the fluidity of the smoke oil in the main oil chamber 160 begins to deteriorate when the main oil chamber 160 has a first air pressure value, the preset air pressure value can be calculated according to the difference between the first air pressure value and the atmospheric pressure. That is, when the air pressure value in the main oil chamber 160 reaches the first air pressure value, the one-way valve 150b should be opened and the air pressure should be added to the main oil chamber 160 through the ventilation oil chamber 190 to improve the fluidity of the smoke oil.
[0053] This embodiment sets a preset value so that the ventilation oil chamber 190 does not need to provide air pressure to the main oil chamber 160 all the time, which can reduce the oil smoke smell in the ventilation oil chamber 190 entering the main oil chamber 160 and affecting the taste of the smoke oil in the main oil chamber 160, and can ensure the purity of the smoke oil in the main oil chamber 160 to a certain extent, and improve the taste. It can be understood that in other embodiments of the present application, the one-way valve 150b can also always work, that is, the gas in the ventilation oil chamber 190 can always enter the main oil chamber 160, and the gas in the main oil chamber 160 can never enter the ventilation oil chamber 190.
[0054] In another embodiment of the present application, see Fig. 9 and Fig.10, when the ventilation component 150 is a one-way valve 150b; the ventilation oil chamber 190 has a connecting port 141 connected to the main oil chamber 160; the one-way valve 150b includes a sealing sheet 1511b; a part of the sealing sheet 1511b is fixedly arranged; the sealing sheet 1511b is attached to the end face of the connecting port 141 facing the main oil chamber 160 under the action of its own gravity and / or elastic force; when the air pressure difference between the main oil chamber 160 and the ventilation oil chamber 190 reaches a preset value, the sealing sheet 1511b is squeezed by the airflow in the ventilation oil chamber 190 and is at least partially separated from the end face of the connecting port 141.
[0055] Before the pressure difference between the main oil chamber 160 and the ventilation oil chamber 190 reaches a preset value, the sealing sheet 1511b is attached to the end surface of the connecting port 141 facing the main oil chamber 160 under the action of its own gravity and / or elastic force, and the ventilation oil chamber 190 is disconnected from the main oil chamber 160, and the gas in the ventilation oil chamber 190 cannot enter the main oil chamber 160. When the pressure difference between the main oil chamber 160 and the ventilation oil chamber 190 reaches a preset value, the gas in the ventilation oil chamber 190 can overcome the gravity and / or elastic force of the sealing sheet 1511b and push the sealing sheet 1511b, so that the sealing sheet 1511b is at least partially separated from the connecting port 141, so that the gas in the ventilation oil chamber 190 can enter the main oil chamber 160. If the gas in the main oil chamber 160 acts on the sealing sheet 1511 b , it will promote the sealing sheet 1511 b to stick to the end surface of the connecting port 141 , so the gas in the main oil chamber 160 cannot enter the ventilation oil chamber 190 .
[0056] In this embodiment, the one-way valve 150b is realized by fitting and separating the sealing sheet 1511b and the end surface of the connecting port 141, and the one-way valve 150b is opened and closed by utilizing the gravity and / or elastic force of the sealing sheet 1511b, thereby making the one-way valve 150b simple in structure, easy to install and low in cost.
[0057] In one embodiment, see Fig. 9 and Fig.10 The sealing sheet 1511b is arranged at the top of the ventilation oil chamber 190, and the sealing sheet 1511b is attached to the outer surface of the top of the connecting port 141 under the action of its own gravity and elastic force.
[0058] In another embodiment of the present application, please refer to Fig.11The one-way valve 150b includes an elastic sheet 151c; the elastic sheet 151c is arranged in the ventilation oil chamber 190; one end of the elastic sheet 151c is fixedly arranged, and the other end of the elastic sheet 151c elastically abuts against the inner wall of the ventilation oil chamber 190; the elastic sheet 151c is concavely arranged in the direction of the ventilation channel 180. In the initial state, the other end of the elastic sheet 151c abuts against the inner wall of the ventilation oil chamber 190 under the action of its own elastic force and gravity, and the ventilation oil chamber 190 is disconnected from the main oil chamber 160; when the gas pressure in the ventilation oil chamber 190 is greater than the gas pressure in the main channel, the gravity and elastic force of the elastic sheet 151c, the other end of the elastic sheet 151c is squeezed by the gas and separated from the inner wall of the ventilation oil chamber 190, and the ventilation oil chamber 190 is connected to the main oil chamber 160. However, if the gas in the main oil chamber 160 wants to enter the ventilation oil chamber 190, the gas acts on the elastic sheet 151c, which will cause the end of the elastic sheet 151c to elastically abut against the inner wall of the ventilation oil chamber 190, thereby disconnecting the ventilation oil chamber 190 from the main oil chamber 160.
[0059] In other embodiments of the present application, the one-way valve 150b may also be a one-way valve 150b structure composed of a valve core and a spring, which is not the only limitation here.
[0060] In one embodiment, see Figure 5 The ventilation oil chamber 190 is disposed in the main oil chamber 160, and the gas flowing out of the ventilation oil chamber 190 can flow directly into the main oil chamber 160 without passing through other structures in the middle, and the setting of the ventilation oil chamber 190 can be realized without changing the structure other than the main oil chamber 160. At the same time, the setting of the ventilation oil chamber 190 does not occupy the extra space of the atomization structure 1000, and does not affect the miniaturization design of the atomization structure 1000. It can be understood that in other embodiments of the present application, the above-mentioned ventilation oil chamber 190 may not be arranged in the main oil chamber 160, but the connecting port 141 of the ventilation oil chamber 190 is connected to the main oil chamber 160; for example, the ventilation oil chamber 190 can be arranged on the outer side of the main oil chamber 160, and then the ventilation oil chamber 190 and the main oil chamber 160 are connected through the ventilation component 150; or, the ventilation oil chamber 190 can also be arranged at the bottom of the main oil chamber 160, that is, the top of the ventilation oil chamber 190 is connected to the bottom of the main oil chamber 160, and then the ventilation component 150 is arranged at the top of the ventilation oil chamber 190.
[0061] In one embodiment, the axial height of the ventilation oil chamber 190 in the main oil chamber 160 is greater than half of the axial height of the main oil chamber 160. That is, the connection port 141 of the ventilation oil chamber 190 is arranged as high as possible in the main oil chamber 160, so that the airflow entering the main oil chamber 160 from the ventilation oil chamber 190 can push the smoke oil downward, which helps to push the smoke oil into the heating element 200.

The structure is simple, the manufacturing and assembly are simple, and the manufacturing cost is low.

When the sleeve 151b is sleeved on the top outer wall of the ventilation oil pipe 140, the sealing sheet 1511b is attached to the top end surface of the ventilation oil pipe 140. An arc groove 1512b is formed between the sealing sheet 1511b and the sleeve 151b.

At the same time, the airway wall of the ventilation channel 180 is at least partially located in the atomization chamber 170, so that the temperature in the atomization chamber 170 can be transferred to the high-viscosity oil in and near the ventilation channel 180 through the airway wall, which increases the fluidity of the smoke oil, thereby enabling the smoke oil to be ventilated smoothly.
