Description

Technical Field

[0001] The present application relates to the technical field of electronic atomization, and in particular to an electronic atomizer and an electronic atomization device with oil back-absorption leakage. Background Art

[0002] The electronic atomizer stores aerosol products, such as e-liquid, inside. Aerosol is formed by heating the aerosol products and is finally inhaled by people through the nozzle at the air outlet.

[0003] At present, aerosol products are stored in electronic atomizers through oil storage cotton, but the oil storage cotton will hide a part of the aerosol product and cannot be used, resulting in a decrease in the number of puffs. Therefore, the problem is solved by using an electronic atomizer with a pure oil tank. Since the oil storage cotton is removed, the stored aerosol product can be utilized to the maximum extent, thereby increasing the number of puffs.

[0004] However, due to the lack of oil storage cotton, the oil cannot be locked to a certain extent, resulting in serious oil leakage problems for this type of electronic atomizer. Excessive aerosol products will penetrate into the atomization core, and then flow to the air inlet to the outside. In addition, during high temperature tests, drop tests, transportation, etc., the oil will continue to leak over time, which is very inconvenient to use. This has become a huge pain point for this type of product and urgently needs to be solved by optimizing the structure. Utility Model Content

[0035] See also Figures 1 to 3 In one embodiment, the present application proposes an electronic atomizer for back-sucking oil leakage, including: a shell 10, an oil storage chamber 20, a ventilation pipe 30, an atomization component 40, an anti-leakage chamber 50, and a first oil guide body 60.

[0036] The outer surface 64 of the housing 10 is provided with an air inlet 11 and an air outlet 12; the air inlet 11 and the air outlet 12 can be circular holes or elliptical holes;

[0037] The oil storage chamber 20 is arranged in the shell 10, and the oil storage chamber 20 is used to store aerosol products; the aerosol product can be tobacco oil, and pure tobacco oil is stored in the oil storage chamber 20, and the capacity can be 2ml, 4ml, 10ml, 16ml or 20ml, etc. Further, the tobacco oil can be tobacco oil of different flavors, such as apple flavor, strawberry flavor, or blueberry flavor, etc.; the shell 10 can be made of plastic material, and further, the shell 10 can be made of transparent plastic material, so that the remaining amount of the aerosol product inside the oil storage chamber 20 can be directly observed from the outside, which is convenient for users to replace or add aerosol products even if necessary, and is more convenient to use.

[0038] The ventilation pipe 30 passes through the oil storage chamber 20, and one end is connected to the air outlet 12; an embodiment is: one end of the ventilation pipe 30 and the shell 10 are designed as an integrally formed structure, thereby reducing assembly parts and making the electronic atomizer more convenient to assemble.

[0039] One end of the atomizer assembly 40 is connected to the ventilation duct 30, and the other end is connected to the air outlet 12. An oil inlet hole 411 is provided on the side of the atomizer assembly 40; the atomizer assembly 40 is used to heat the aerosol product that penetrates through the oil inlet hole 411 to form an aerosol, which can be inhaled by people through the ventilation duct 30 and the air outlet 12.

[0040] The anti-leakage chamber 50 is disposed in the housing 10 ; the anti-leakage chamber 50 is disposed below the oil storage chamber 20 , and the anti-leakage chamber 50 can store excess aerosol products that leak into the atomization assembly 40 .

[0041] A portion of the first oil guide body 60 covers the oil inlet hole 411, and the aerosol product in the oil storage chamber 20 penetrates into the first oil guide body 60, and then passes through the oil inlet hole 411 into the atomizer assembly 40, and another portion of the first oil guide body 60 is placed in the anti-leakage chamber 50. The first oil guide body 60 can be made of a material that is easy to guide oil, such as cotton fiber.

[0042] In this way, a part of the first oil guide body 60 covers the oil inlet hole 411, thereby locking the oil, preventing the aerosol product in the oil storage chamber 20 from penetrating into the atomizer assembly 40 too quickly, and the leaked part of the aerosol product can be temporarily stored in the leak-proof chamber 50 through the leak-proof chamber 50, and it is not easy to flow out through the air outlet 12; further, another part of the first oil guide body 60 is placed in the leak-proof chamber 50, so that the aerosol product that has penetrated into the leak-proof chamber 50 can be sucked back through the first oil guide body 60, so that it can enter the atomizer assembly 40 again for use. In this way, the electronic atomizer can prevent the aerosol product from flowing out through the air inlet hole 11 through the first oil guide body 60 and the leak-proof chamber 50, and the aerosol product in the leak-proof chamber 50 can be sucked back through the first oil guide body 60, making the electronic atomizer more convenient to use.

[0043] See also Figure 3 In one embodiment, the first oil guide body 60 includes a curved portion 61 and two extension portions 62. The curved portion 61 wraps around a portion of the side surface of the atomizer assembly 40 and covers the oil inlet hole 411. The two extension portions 62 are respectively arranged at both ends of the curved portion 61, and the ends of the extension portions 62 are placed in the anti-leakage cavity 50.

[0044] The bent portion 61 can be adapted to the portion of the atomizer assembly 40 where the oil inlet hole 411 is provided. The bent portion 61 allows the portion of the first oil guide body 60 in contact with the atomizer assembly 40 to fit more closely, thereby preventing a large gap from being formed between the first oil guide body 60 and the side of the atomizer assembly 40, making it easier for the aerosol product to penetrate into the oil inlet hole 411 through the first oil guide body 60 and reach the interior of the atomizer assembly 40.

[0045] The extension portion 62 and the bending portion 61 are designed as an integrally formed structure, and the end of the extension portion 62 can be flat or serrated, so as to facilitate the rapid reabsorption of the aerosol product leaked into the anti-leakage cavity 50.

[0046] See also Figure 3 and Figure 4In one embodiment, the bent portion 61 and the two extension portions 62 form a U-shaped sheet structure, and the first oil guide body 60 is arranged vertically. The atomizer assembly 40 is arranged vertically, and the first oil guide body 60 is formed in the form of outer cotton wrapping, half-wrapping the atomizer assembly 40, so that the assembly between the first oil guide body 60 and the atomizer assembly 40 is more convenient, and the vertical arrangement of the first oil guide body 60 and the sheet structure design can save the horizontal space of the electronic atomizer, and the structural design is more reasonable.

[0047] See also Figures 2 to 5 In one embodiment, the electronic atomizer further includes a bracket 70, which is located in the shell 10. The bracket 70 is provided with a lower oil channel 71. One end of the lower oil channel 71 is connected to the oil storage chamber 20, and the other end is provided with a through hole 72. The through hole 72 is arranged at a relative interval with the oil inlet hole 411, and the bent portion 61 covers the through hole 72 and the oil inlet hole 411 at the same time.

[0048] The bracket 70 can be made of plastic material and is located below the oil storage chamber 20. The aerosol product in the oil storage chamber 20 can flow into the through hole 72 through the lower oil channel 71 under the action of gravity, and then into the curved portion 61. The curved portion 61 partially locks the oil, so that the aerosol product slowly passes through the oil inlet hole 411 from the through hole 72, penetrates into the interior of the atomizer assembly 40, is heated to form an aerosol, and the aerosol finally passes through the ventilation pipe 30 and the air outlet 12, so that the user can inhale.

[0049] See also Figure 2 and Figure 3 In one embodiment, the electronic atomizer further includes a first seal 90, which is disposed inside the shell 10. The first seal 90 and a portion of the inner wall of the shell 10 form an oil storage chamber 20. The first seal 90 is provided with a lower oil hole 91 and a mounting hole 92. The lower oil channel 71 is connected to the lower oil hole 91, and one end of the ventilation pipe 30 is placed in the mounting hole 92 and connected to the atomization assembly 40.

The bracket 70 and the two pressing portions 73 form a receiving groove 74, and the first oil guide body 60 is located in the receiving groove 74. The inner wall of the receiving groove 74 abuts against the curved portion 61 and at least part of the extending portion 62, and the end of the pressing portion 73 is placed in the anti-leakage cavity 50.

[0052] The pressing portion 73 can facilitate the installation and positioning of the first oil guide body 60, and the abutment of the first oil guide body 60 and the atomizer assembly 40 can be pressed to make the connection between the first oil guide body 60 and the atomizer assembly 40 more tightly abutted, preventing the first oil guide body 60 from being located at the outer edge of the oil inlet hole 411 and the through hole 72 to form a gap, and the inner wall of the accommodating groove 74 forms a certain pressure on the abutment of the first oil guide body 60, so that the first oil guide body 60 is located between the oil inlet hole 411 and the through hole 72. The porosity is greater than the porosity of the first oil-conducting body 60 at the point where it is pressed, so that the aerosol product in the oil storage chamber 20 mainly penetrates into the interior of the atomizing assembly 40 through the through hole 72, the first oil-conducting body 60, and the oil inlet hole 411 in sequence, forming an effective oil lock. Excess aerosol product will penetrate into the anti-leakage chamber 50 for storage, and will also be sucked back through the first oil-conducting body 60 located in the receiving groove 74 for use. While preventing oil leakage, the number of puffs can be guaranteed to a greater extent, making the electronic atomizer more convenient to use.

[0053] See also Figure 4 and Figure 5 In one embodiment, the receiving groove 74 is an arc-shaped structure, and the inner wall of the receiving groove 74 is matched with the outer side surface of the first oil guide body 60. In turn, the bracket 70 and the first oil guide body 60 can be connected more closely, and the pressure distribution of the inner wall of the receiving groove 74 on the abutted part of the first oil guide body 60 can be more reasonable, preventing the formation of a large gap, so that the aerosol product in the oil storage cavity 20 mainly penetrates into the interior of the atomization assembly 40 through the through hole 72, the first oil guide body 60, and the oil inlet hole 411 in turn, thereby enhancing the oil locking effect.
