Description

[0001] This invention patent application is a divisional application of the invention patent application with application number CN201810350370.6, application date April 18, 2018, and invention title "A Double-Layer Heating Structure Atomizing Generator". Technical Field

[0002] This invention relates to an atomizing device with a double-layer heating structure. Background Technology

[0003] A currently used electronic cigarette atomizer includes an atomizing component, an e-liquid storage component, a battery component, and a control component. The atomizing component has an air intake. The control component is connected to the atomizing component. The e-liquid storage component is connected to the atomizer of the atomizing component via wicking cotton, facilitating the entry of e-liquid from the storage component into the atomizer. The battery component provides power to the control and atomizing components. The atomizing component contains a heating wire wound around the wicking cotton. During use, the atomizer operates at a constant power to atomize the e-liquid. The wicking cotton absorbs a fixed amount of e-liquid each time. If a large volume of vapor is inhaled at once, more e-liquid needs to be atomized, but the wicking cotton cannot absorb enough, potentially causing the heating wire in the atomizer to burn out. This is not ideal for people with large inhalations. Summary of the Invention

[0030] A connector 5 is provided on the base 1. The connector 5 has a first oil passage 51 and a second oil passage 52. The first oil passage 51 is located above and connected to the first oil hole 3613. The second oil passage 52 is located above and connected to the oil inlet 13. A connecting channel 53 is provided in the connector 5, located above the atomizing channel 32. A top cover 6 is provided on the upper part of the connector 5. A transparent ring 7 is also provided between the top cover 6 and the connector 5. An air outlet channel 61 is provided in the top cover 6, located above the connecting channel 53.

An air regulating ring 8 is provided around the base 1, and an air regulating hole 81 is provided on the air regulating ring 8, which corresponds to the air inlet 14.

[0031] The airflow design is as follows: Rotate the air regulating ring 8 to align the air regulating hole 81 with the air inlet hole 14. The overlap area between the air regulating hole 81 and the air inlet hole 14 can adjust the amount of air entering. The gas passes sequentially through the air regulating hole 81, the air inlet hole 14, the atomizing outer hole 3631, the atomizing inner hole 33, the atomizing channel 32, the connecting channel 53, and the air outlet channel 61, and finally flows out from the mouthpiece for inhalation. After the outside air enters the atomizing outer hole 3631, it begins to move in three directions: upward, downward, and horizontally. It enters the first heating mesh 34 upward, the second heating mesh 35 downward, and the atomizing inner hole 33 horizontally. After gathering in the atomizing inner hole 33, it flows upward and enters the atomizing channel 32.

[0032] The oil channel design is as follows: E-liquid in the oil storage tank 4 is injected through the oil injection hole 62. The sliding cover 63 is pushed horizontally, and the sliding cover 63 exposes the oil injection hole 62 in the upper cover 6. At this time, e-liquid can be injected into the oil storage tank 4. After it is full, the sliding cover 63 is pushed in the opposite direction, and the sliding cover 63 seals the oil injection hole 62 to prevent e-liquid from leaking out. The e-liquid in the oil storage tank 4 flows directly downwards to the first heating mesh 34 via the first oil passage 51 and the first oil hole 3613, where it is atomized. Alternatively, it flows downwards through the second oil passage 52, the oil inlet 13, the gap 21, and the second oil hole 3624 to the second heating mesh 35, where it is atomized. In this case, the e-liquid first flows downwards through the second oil passage 52 and the oil inlet 13, then horizontally through the gap 21, and finally upwards into the second oil hole 3624, flowing upwards to the second heating mesh 35. These two paths coexist, operate independently, and do not interfere with each other, providing e-liquid to both the first and second heating meshes 34 for atomization.

[0033] The circuit design is as follows: the positive terminal of the power supply is connected to the negative electrode 25, and the current flows through the fourth shaft 314, the third shaft 313, and the second shaft 312. It is isolated on the first shaft 311 because the first shaft 311 is insulating and non-conductive. The current on the fourth shaft 314, the third shaft 313, and the second shaft 312 enters the inner side of the first heating mesh 34 and the inner side of the second heating mesh 35. The current flows through the inner side of the first heating mesh 34 and the inner side of the second heating mesh 35 to the outer side of the first heating mesh 34 and the outer side of the second heating mesh 35, respectively. The outer side of the first heating mesh 34 and the outer side of the second heating mesh 35 are connected to the outer shell 36. The outer shell 36 is connected to the base 1. The base 1 is connected to the lower cover 2. The current flows to the outer shell 36 and the base 1 and returns to the negative terminal of the power supply, or the current on the outer shell 36 flows to the second shell 362 and the lower cover 2, forming a loop.

[0034] During use, the e-liquid is atomized on the outside of the first heating mesh 34 and the second heating mesh 35. The atomized e-liquid flows out of the mouthpiece through the atomization inner hole 33, the atomization channel 32, the connecting channel 53, and the air outlet channel 61, and is then inhaled. The atomized e-liquid is carried out by the air. This design can meet the needs of large lung capacity. The first heating mesh 34 and the second heating mesh 35, which are set up at the top and bottom, work at the same time. The structure is novel. The first heating mesh 34 and the second heating mesh 35 are set in a mesh shape, which also facilitates the entry of e-liquid and the evaporation of the atomized e-liquid.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
