Description

Technical Field

[0001] The present invention relates to the technical field of atomizers, and in particular to an oil-core separation atomizer, an aerosol generating device and an oil-core separation control method. Background Art

[0002] Since the smoke produced by burning tobacco contains nicotine, tar, carbon monoxide and other substances that are harmful to health, smoking has become the largest preventable cause of death in the world today, and people around smokers will also suffer harm by inhaling secondhand smoke.

[0003] Therefore, with the advancement of science and technology and people's increasing attention to health, the use of electronic cigarettes is becoming more and more widespread. Electronic cigarettes are an electronic product that produces smoke for users to inhale by heating the e-liquid. They generally include two parts: an atomizer and a power supply device. The power supply device supplies power to the atomizer. By atomizing the e-liquid to produce smoke, compared with the direct combustion of tobacco, it effectively reduces the production of harmful substances and reduces the harm to smokers and people around them to a certain extent.

[0004] In traditional aerosol generating devices, the e-liquid is always immersed in the atomizer core through the liquid inlet hole. Since the liquid-conducting medium in the atomizer core is a loose porous material, the liquid storage cavity is connected or semi-connected with the external airway environment. In order to facilitate transportation and storage, traditional aerosol generating devices use silicone sealing plugs for the air inlet and outlet to seal the entire device, so that the device is in a sealed state as a whole.

[0005] However, due to the pressure difference between the liquid storage chamber and the inlet and outlet channels, as well as the loose and porous characteristics of the liquid-conducting medium, the pressure on both sides will gradually balance, causing the e-liquid to leak from the liquid storage chamber into the inlet and outlet channels, or even leak out of the device. In addition, there will be a period of time between the electronic cigarette leaving the factory and being sold. If the atomizer core is immersed in e-liquid for a long time, the e-liquid will easily deteriorate and the taste will deteriorate, thus affecting the user experience.

[0006] Therefore, the prior art needs to be developed. Summary of the invention

[0007] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to propose an oil-core separated atomizer, an aerosol generating device and an oil-core separation control method, aiming to solve the problem in the prior art that the atomizer core is immersed in the e-liquid for a long time, thereby causing the e-liquid to deteriorate, the taste to deteriorate, and the oil leakage during transportation.

[0038] Please refer to Figures 1 to 7 The present invention provides an oil-core separated atomizer 100, comprising an oil cup 10, an oil control seat 20, an atomizing core 30 and a base 40, wherein the oil cup 10 is connected to the oil control seat 20 to form an oil storage chamber 11, wherein the oil storage chamber 11 is used to store the e-liquid, and the base 40 is rotatably connected to the oil control seat 20 to form an oil supply chamber 41, and the base 40 and the oil control seat 20 can rotate around their respective centers.

[0039] The atomizer core 30 is installed in the oil supply cavity 41, the oil control seat 20 is provided with a first oil inlet hole 21, and the upper end surface of the base 40 is provided with a second oil inlet hole 42. The oil control seat 20 is rotated to make the first oil inlet hole 21 and the second oil inlet hole 42 overlap or staggered.

[0040] like Figure 3 As shown, when the atomizer 100 is not in use, the first oil inlet hole 21 of the oil control seat 20 is staggered with the second oil inlet hole 42 of the base 40 by rotating the oil control seat 20, so that the oil storage chamber 11 is isolated from the oil supply chamber 41, and the atomizer core 30 is separated from the tobacco oil. The tobacco oil is sealed in the oil storage chamber 11, so as to avoid leakage of the atomizer 100 during transportation, storage or idleness, thereby ensuring that the tobacco oil does not deteriorate, and improving the smoking taste and user experience.

[0041] like Figure 4 As shown, when the atomizer 100 needs to be used, the oil control seat 20 is rotated to make the first oil inlet hole 21 of the oil control seat 20 coincide with the second oil inlet hole 42 of the base 40, so that the oil storage chamber 11 is connected to the oil supply chamber 41. At this time, the atomizer 100 is in a usable state, and the tobacco oil in the oil storage chamber 11 can flow into the oil supply chamber 41 through the first oil inlet hole 21 and the second oil inlet hole 42, and can be heated and atomized by the atomizer core 30 to generate aerosol.

[0042] The present invention can switch the connection or blocking state of the oil storage chamber 11 and the oil supply chamber 41 by rotating the oil control seat 20, thereby solving the problem in the prior art that the atomizer core 30 is immersed in the e-liquid for a long time, thereby causing the e-liquid to deteriorate, the taste to deteriorate, and the oil leakage during transportation. The oil control seat 20 can be rotated repeatedly, the operation is simple and fast, and the user experience is effectively improved.

[0043] Preferably, the edges of the first oil inlet hole 21 and the second oil inlet hole 42 are arranged as arc surfaces, which can accelerate the speed at which the smoke oil flows into the oil supply cavity 41 .

[0044] Please refer to Figure 2 and Figure 4The oil cup 10 is provided with an air outlet pipe 12 , and the oil control seat 20 is provided with a hollow ventilation column 22 connected with the air outlet pipe 12 .

[0045] The base 40 includes a bracket 43 and a mounting platform 44 embedded in the bottom of the bracket 43. The upper end of the bracket 43 is provided with a through hole 431. The lower end of the air outlet pipe 12 is inserted into the through hole 431, and forms the oil supply chamber 41 together with the inner wall of the bracket 43 and the upper end surface of the mounting platform 44. The upper end of the atomizer core 30 is fixed in the ventilation column 22, and the lower end is fixed on the mounting platform 44. The oil control seat 20 and the air outlet pipe 12 separate the oil storage chamber 11 and the oil supply chamber 41, and the installation is convenient and quick.

[0046] Specifically, a clamping ring 23 is provided in the ventilation column 22, the lower end of the air outlet pipe 12 abuts against the clamping ring 23, and the upper end of the atomizer core 30 abuts against the clamping ring 23, thereby achieving position limiting, facilitating structural installation, and improving assembly efficiency.

[0047] Preferably, a sealing ring 36 is sleeved on the upper end of the atomizer core 30 to abut against the inner wall of the outlet pipe 12 to improve the sealing performance and ensure that the oil control seat 20 and the atomizer core 30 rotate around the center.

[0048] Please refer to Figure 5 The mounting platform 44 is axially provided with a groove 45 and a protruding column 46 provided at the bottom of the groove 45. The protruding column 46 is penetrated by an air inlet 461, and the air inlet 461 is connected to the inside of the atomizer core 30. The bottom of the atomizer core 30 is accommodated in the groove 45 and sleeved on the protruding column 46, so as to stably fix the atomizer core 30.

[0049] When the oil control seat 20 is rotated, the first oil inlet hole 21 of the oil control seat 20 overlaps with the second oil inlet hole 42 of the base 40, so that the oil storage chamber 11 is connected to the oil supply chamber 41. At this time, the atomizer 100 is in a usable state, and the tobacco oil in the oil storage chamber 11 can flow into the oil supply chamber 41 through the first oil inlet hole 21 and the second oil inlet hole 42, and can be heated and atomized by the atomization core 30 to generate aerosol. At the same time, external gas enters through the air inlet hole 461 and drives the aerosol generated by the heating of the atomization core 30, which is discharged through the air outlet pipe 12 for the user to inhale.

[0050] Preferably, an air inlet groove 441 connected to the air inlet hole 461 is provided at the bottom of the mounting platform 44, and the air inlet groove extends from the edge of the mounting platform 44 to the air inlet hole 461, which can prevent the air inlet hole 461 from being blocked and ensure the normal circulation of gas.

[0051] Please refer to Figure 2 and Figure 6 As an embodiment, a protrusion 24 is provided on the inner wall of the oil control seat 20, and a slide groove 432 is provided on the outer wall of the bracket 43. The protrusion 24 slides in the slide groove 432. The starting position of the oil control seat 20 is the abutting end surface of the protrusion 24 and the slide groove 432, which is convenient for the user to confirm that the oil control seat 20 is rotated into place so that the first oil inlet hole 21 can be completely staggered or overlapped with the second oil inlet hole 42.

[0052] Preferably, a pair of the protrusion 24 and the slide groove 432 are provided and are symmetrically arranged respectively, and the rotation range of the oil control seat 20 is 0-180 degrees.

[0053] In this embodiment, a sealing member 25 is provided between the oil control seat 20 and the bracket 43. The sealing member 25 is made of silicone material, which can prevent the oil from overflowing and improve the barrier sealing effect.

[0054] Please continue to refer to Figure 2 The atomizer core 30 includes an outer cover 31, a fixing frame 32, an oil guide member 33 and a heating member 34. The oil guide member 33 is sleeved outside the heating member 34 and accommodated in the fixing frame 32. The outer cover 31 is sleeved outside the fixing frame 32 and forms an oil control chamber 35 with the fixing frame 32. The outer cover 31 is provided with a first oil guide hole 311 communicating with the oil control chamber 35. The fixing frame 32 is provided with a second oil guide hole 321 communicating with the oil control chamber 35.

[0055] In actual use, the oil guide member 33 generally uses oil guide cotton, and the heating member 34 includes a heating net and pins. The mounting platform 44 is provided with a through hole 442 for the pins to pass through, and the pins are connected and pressed by electrodes 443.

[0056] The smoke oil in the oil supply chamber 41 enters the oil control chamber 35 through the first oil guide hole 311, forms an oil film in the oil control chamber 35, and penetrates into the oil guide member 33 through the second oil guide hole 321. Due to the water absorption, water permeability and waterproofness of the oil guide member 33, the oil guide member 33 plays the role of storing and locking oil, thereby providing the required smoke oil to the heating element 34.

[0057] The present invention also provides an aerosol generating device, comprising the above-mentioned atomizer 100 and a battery rod connected to the bottom of the atomizer 100, wherein the battery rod provides power to the atomizer 100. The use of the above-mentioned atomizer 100 can prevent the aerosol generating device from leaking or seeping during transportation or storage, and can block the oil between the oil storage chamber 11 and the oil supply chamber 41 during idleness, thereby effectively preventing the oil from being contaminated or deteriorated, ensuring the smoking taste, and improving the user experience.

[0058] The present invention also provides an oil core separation control method, using the atomizer 100 as described above, specifically comprising the following steps:

[0059] The oil cup 10 is connected to the oil control seat 20 and sleeved on the base 40 and the atomizer core 30. The upper end surface of the oil control seat 20 and the oil cup 10 form an oil storage cavity 11, and the lower end surface of the oil control seat 20 and the base 40 form an oil supply cavity 41;

[0060] The oil control seat 20 is rotated along the first direction to stagger the first oil inlet hole 21 of the oil control seat 20 and the second oil inlet hole 42 of the base 40, so that the oil storage chamber 11 is isolated from the oil supply chamber 41, and the atomizer core 30 is separated from the oil. At this time, the atomizer 100 is in an unused state, and the oil is sealed in the oil storage chamber 11, so as to avoid leakage of the atomizer 100 during transportation, storage or idleness, thereby ensuring that the oil does not deteriorate and improving the smoking taste and use experience.

[0061] The oil control seat 20 is rotated along the second direction so that the first oil inlet hole 21 of the oil control seat 20 coincides with the second oil inlet hole 42 of the base 40, so that the oil storage chamber 11 is connected with the oil supply chamber 41. At this time, the atomizer 100 is in use, and the tobacco oil in the oil storage chamber 11 can flow into the oil supply chamber 41 through the first oil inlet hole 21 and the second oil inlet hole 42, and can be heated and atomized by the atomizer core 30 to generate aerosol.

[0062] In this embodiment, the first direction and the second direction are oppositely arranged. For example, if the first direction is clockwise, the second direction is counterclockwise. The arrangement can be made according to actual conditions.

[0063] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here.
