Electronic cigarettes can also be called aerosol generating devices. The atomizer in an electronic cigarette is a device that atomizes the test liquid.

[0003] In current atomizers, the path for the smoke oil to reach the heating element overlaps with the path for gas exchange. The mixing of the oil path and the gas path makes it easy for bubbles to form when the heating element heats the oil, which can easily lead to insufficient oil supply, causing local overheating of the heating element and burning of the core, shortening the life of the atomizer. Summary of the invention

[0008] Furthermore, the oil-gas path separation atomizer also includes an adjustment ring, which is arranged at the bottom of the ventilation component to change the position of the ventilation component in the ventilation hole, thereby adjusting the height difference between the top surface of the ventilation component and the interface.

[0009] Furthermore, an atomizer is sleeved on the heating element, and the atomizer is used to seal the gap between the heating element and the atomizer bin.

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention 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 invention and are not intended to limit the present invention.

[0028] Please also read Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6, the oil-gas separation atomizer provided by the embodiment of the present invention is now described. The oil-gas separation atomizer includes a shell 22 and an atomizer assembly, the atomizer assembly is arranged in the shell 2, and the atomizer assembly and the shell 2 form an oil bin 19, wherein the shell 2 is hollow and a suction nozzle 15 is opened on the top, and the passage of the suction nozzle 15 is connected to the atomizer assembly through a connecting pipe 5, and the two ends of the connecting pipe 5 are respectively connected to the suction nozzle 15 and the atomizer assembly. Among them, the atomizer assembly includes an oil seal 4, an atomizer bin 9 and a heating element 3, the oil seal 4 is used to seal the smoke oil in the oil bin 19, the atomizer bin 9 is used to provide a space for forming smoke, the oil seal 4 and the inner wall of the shell 2 are abutted, the atomizer bin 9 is arranged below the oil seal 4, and the heating element 3 is arranged inside the atomizer bin 9, and the heating element 3 is used to heat the smoke oil so that the smoke oil forms an aerosol smoke. The oil seal 4 is provided with an oil hole 10 and a vent 11. As the names imply, the oil hole 10 is used to circulate the smoke oil, and the vent 11 is used to circulate ventilation. The vent 11 is provided with a ventilator 6 (here, the vent 6 is a component with many tiny micropores), and the airflow is ventilated with the oil bin 19 through the vent 6. After the smoke oil flows out of the oil bin 19, it flows to the heating element 3 to supply oil to the heating element 3. The vent 6 introduces the airflow into the oil bin 19, so that the smoke oil in the oil bin 19 flows out, and the airflow continuously flows into the oil bin 19, so that the smoke oil and gas in the oil bin 19 are balanced, and the smoke oil in the oil bin 19 enters the atomization bin 9 through an interface 21, and a smoke transition cavity is formed in the atomization bin 9. The aforementioned interface 21 refers to the interface between the oil bin 19 and the smoke transition cavity. The smoke oil enters the atomization chamber 9, is heated by the heating element 3 to generate smoke, and the smoke enters the smoke transition chamber and flows out from the connecting pipe 5 and the mouthpiece 15. The heating element 3 heats the smoke oil to generate aerosol smoke. Among them, the top surface of the ventilation element 6 needs to be higher than the interface 21 between the oil tank 19 and the smoke transition chamber, and the interface 21 is the interface between the oil tank 19 and the atomization chamber 9. The smoke oil in the oil hole 10 and the smoke oil in the vent 11 form a height difference, and the height difference of the smoke oil in the oil hole 10 is greater than the height of the smoke oil in the vent 11. Since the density of oil is greater than the density of air, the air needs to overcome the gravity of the oil to float up, and the gravity of the oil in the heating element 3 is greater than the gravity of the oil in the ventilation element 6, so it is easier for the gas to pass through the ventilation element 6, then the smoke oil is easier to flow from the oil hole 10 to the heating element 3, and the airflow is easier to enter the oil bin 19 from the ventilation hole 11 and the ventilation element 6, so that the oil and ventilation are synchronized and separated. While the smoke oil flows out of the oil hole 10, the airflow continuously enters the oil bin 19 from the ventilation hole 11. However, the smoke oil is only continuously conducted to the heating element 3 through the oil hole 10, and the airflow continuously enters the oil bin 19 from the ventilation hole 11.

[0029] Compared with the prior art, the oil-gas path separation atomizer provided by the present invention has an oil hole 10 on the oil seal 4, an oil bin 19 is formed in the shell, the oil flows from the oil bin 19 to the bottom of the heating element 3 through the oil hole 10, the oil storage member 8 and the heating element form a cavity, and the oil flows in from the oil hole 10 to form an oil cavity 20. The oil hole 10 and the air hole 11 are respectively provided on the oil seal 4, and the top surface of the ventilation member 6 is higher than the top surface of the interface 21. The oil enters the heating element 3 from the oil hole 10, and the external gas enters the oil bin 19 from the ventilation member 6. Since the density of oil is greater than the density of air, the air needs to overcome the gravity of the oil to float up. The gravity of the oil in the heating element 3 is greater than the gravity of the oil in the ventilation member 6, so the gas is more likely to pass through the ventilation member 6, thereby achieving the separation of the oil path and the gas path. The oil tank 19 is kept in dynamic balance with the atmospheric pressure outside. Due to the separation of the oil circuit and the gas circuit, the ventilation air will not affect the speed of the oil in the oil tank 19 flowing out from the oil hole 10. The oil storage speed is stable and will not be slow or fast, so that the oil distribution on the heating element 3 is more uniform, and the atomization efficiency is higher; the phenomenon of the heating element 3 being partially overheated and the core being burnt due to insufficient oil supply is avoided, and the service life of the atomizer is extended. The oil tank 19 is formed in the shell 2. When in use, the oil enters the heating element 3 from the oil tank 19 through the oil hole 10, and the smoke generated by the heating element 3 heating the oil flows out from the connecting pipe 5. The oil tank 19 can be filled with oil at the beginning. After the oil is reduced, the external gas enters from the bottom of the atomizer, passes through the ventilation element 6, and the external gas enters the oil tank 19 from the ventilation element 6, so as to achieve the separation of the oil circuit and the gas circuit; at the same time, the pressure in the oil tank 19 and the external atmospheric pressure are kept in dynamic balance.

[0030] Preferably, please also refer to Figures 1 to 5 As one of the embodiments of the present invention, the oil bin is a cavity formed by the shell and the oil seal. From the figure, the oil bin is the part of the cavity formed above the shell and the oil seal. The smoke oil flows out of the oil bin through the oil hole. The smoke oil can be directly dripped on the top surface of the heating element, or it can be transferred to the heating element through other auxiliary components such as sponges to generate heat and smoke oil. Therefore, in order to form the aforementioned height difference and pressure difference of the oil, the definition of the interface used in this embodiment is: the top surface of the ventilation element 6 and the lowest horizontal surface in contact with the smoke oil in the oil hole 10 form a height difference. Here, it can also be understood that the interface 21 is the lowest horizontal surface of the oil hole 10.

[0031] Preferably, please also refer to Figures 1 to 5As another specific embodiment of the present invention, in this embodiment, the oil-gas separation atomizer also includes an oil storage member 8, which seals the base 1 to prevent the smoke oil from leaking downward from the base 1. The oil storage member 8 can be arranged between the heating element 3 and the base 1, and an oil cavity 20 can be formed between the oil storage member 8 and the heating element 3. The oil cavity 20 refers to the cavity formed between the oil storage member 8 and the heating element 3. Here, the oil bin 19 is no longer exactly the same as the "oil bin 19" of the previous embodiment. The oil bin 19 of this embodiment not only includes the "oil bin 19" of the previous embodiment, but also includes the aforementioned oil cavity 20. Here, the entire oil bin 19 can be referred to as including a large oil bin (the oil bin 19 in the previous embodiment) and a small oil bin (the oil cavity 20 mentioned above). At this time, the interface is the top of the heating element 3 (both embodiments of the present invention are heating at the top of the heating element 3). An oil hole 10 is provided on the oil seal 4, and the oil flows from the oil tank 19 through the oil hole 10 to the bottom of the heating element 3, and an oil cavity 20 is formed between the oil storage 8 and the heating element 3. When the user is using the atomizer, whether the atomizer is tilted at a certain angle or lying down to make it stand upside down, the heating element 3 can always be in full contact with the oil, thus avoiding the phenomenon of dry burning of the heating element 3 and extending the service life of the atomizer. The top of the heating element 3 is heated, and the condensed liquid generated in the airway is absorbed by the heating element 3 after reflux and will not enter the mouth; the residual heat after heating is absorbed by the oil cavity 20, and the heat at the bottom of the atomizer is very small, so condensation is not easy to form; ( Figure 5 The upward arrow in the figure indicates the direction of smoke and heat absorption, and the downward arrow indicates that the condensate is recovered by the heating element 3). In addition, the heating position of the heating element 3 can also be the bottom or the inside; and the heating element can be a cotton core heating element or a ceramic heating element; the top heating method mentioned above is the preferred method for ceramic heating elements. The aforementioned interface 21 can also be the bottom surface of the heating element 3.

[0032] Preferably, please also refer to Figures 1 to 4 In this embodiment, the ventilation member 6 is columnar and porous. In addition, the oil-gas separation atomizer further includes an adjusting ring 12, which is arranged at the bottom of the ventilation member 6. The height difference between the heating element 3 and the top surface of the ventilation member 6, or the height difference between the lowest horizontal surface in contact with the smoke oil in the oil hole 10 and the top surface of the ventilation member 6 can be adjusted by changing the height of the adjusting ring 12. To achieve the speed control of ventilation, thereby controlling the speed of oil intake, a through hole is provided on the adjusting ring 12, and the size of ventilation can be adjusted by controlling the size of the through hole, thereby achieving the control of the oil intake amount. It should be noted that the columnar shape of the ventilation member 6 can be a cylindrical, triangular prism, quadrangular prism, polygonal prism and the like; in addition, the hole on the ventilation member 6 needs to pass through the ventilation member 6. The heating element 3 is provided with an atomizer 7, which is essentially a sealing member, and its function is to seal the gap between the atomizer bin 9 and the heating element 3.

[0033] Please also refer to Figures 1 to 4 The shell 2 is provided with a connecting ring 13, the top of the oil seal 4 is provided with a plug-in tube 14, the suction nozzle 15 is connected to the connecting ring 13, one end of the connecting tube 5 is plugged into the connecting ring 13, and the other end is plugged into the plug-in tube 14. The connecting ring 13 and the plug-in tube 14 facilitate the installation and positioning of the connecting tube 5. The size of the inlet end of the suction nozzle 15 is larger than the size of the connecting ring 13, so that the user can inhale more smoke. When in use, the user aligns his mouth with the suction nozzle 15 and inhales. The larger suction nozzle 15 makes it easier for the user to inhale the smoke. The smoke generated by the heating element 3 flows from the connecting tube 5 to the connecting ring 13 and the suction nozzle 15, and is inhaled into the mouth of the user.

[0034] Please also refer to Figures 1 to 4 In this embodiment, a buckle 16 is provided on the atomization bin 9, and a bayonet 17 is provided on the base 1. When the atomization bin 9 and the base 1 are connected, the buckle 16 is engaged with the bayonet 17. In this embodiment, the number of the buckle 16 and the bayonet 17 is set to two, the buckle 16 is provided on both sides of the bottom of the atomization bin 9, and the buckle 16 is provided on both sides of the base 1. Two electrode nails 18 are installed at the bottom of the base 1, and the electrode nails 18 are electrically connected to the heating element 3. In this embodiment, the atomizer 7, the oil storage part 8 and the oil sealing part 4 are all made of silicone. The heating element 3 has 2 electrode wires, each of which is connected to an electrode nail 18. When the atomizer is actually used, it will be inserted into the electronic cigarette host, which is provided with a battery and two electrodes. The electrodes on the host will abut against the electrode nails 18 to form an electrical connection, so that the heating element 3 can be powered on and work.

[0035] An air inlet and an air duct are also provided on the main unit; an air inlet may also be provided at the bottom of the atomizer; air enters the main unit from the air inlet on the main unit, passes through the air duct, and enters the atomization bin 9 from the air inlet at the bottom of the atomizer, driving the atomized gas generated by the heating element 3 to pass through the connecting pipe and come out from the suction nozzle 15.
