Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomizing core technology, specifically to a leak-proof atomizing core structure based on self-exhausting negative pressure isolation. Background Technology
[0002] Atomizing coils, also known as atomizers, are devices used to convert liquids into mist particles. They are widely used in pharmaceuticals, cigarettes, cosmetics, and many other fields. By heating or other methods, they break down liquids into fine mist particles, thereby increasing the surface area of the liquid and making it easier to inhale or absorb. However, existing atomizing coils are prone to leakage during use.
[0003] To overcome the above-mentioned defects, Chinese patent (publication number: CN220360103U) discloses a leak-proof atomizing core structure for an atomizing device, including an electrode ring, an insulating ring fixedly installed at the bottom of the electrode ring, an insulating threaded sleeve fixedly installed at the bottom of the insulating ring, an oil-controlling small hole shell fixedly installed at the bottom of the insulating threaded sleeve, an leak-proof oil filter element fixedly installed near the center inside the oil-controlling small hole shell, a fixing buckle fixedly installed at the bottom of the oil-controlling small hole shell, a fixing ceramic seat fixedly installed near the center at the bottom of the fixing buckle, a corrosion-resistant foamed nickel fixedly installed at the bottom of the fixing ceramic seat, a silicone sealing ring fixedly installed at the bottom of the corrosion-resistant foamed nickel, and a smoke guiding component fixedly installed near the center at the bottom of the silicone sealing ring. The placement of the smoke guiding component can guide the direction of the mist flow, thus achieving the best atomization effect and facilitating the use of the equipment.
[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: when the atomizing core atomizes the oil, it needs to heat the oil through its internal heating mesh to form a mist. In actual use, the atomization rate of the oil by the heating mesh is limited, and too fast an input of oil can easily cause the atomizing core to leak. Utility Model Content
[0005] The purpose of this invention is to provide a leak-proof atomizing core structure based on self-venting negative pressure isolation, so as to solve the problem in the above-mentioned background technology that the heating mesh has a limited atomization rate of oil, and that too fast input of oil can easily lead to oil leakage of the atomizing core.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof atomizing core structure based on self-exhausting negative pressure isolation, including an outer cover, a bottom cover fixedly connected to the bottom of the outer cover, and a sealing ring fixedly connected to the middle of the outer cover;
[0007] The top of the bottom cover is fixedly connected to an oil storage cotton, and the outer side of the oil storage cotton and the inner side of the sealing ring are fitted together to form a sealing structure. The outer cover has a temporary storage cavity inside, and an isolation tube is provided between the temporary storage cavity and the oil storage cotton. An oil guide core is installed inside the isolation tube, and the two ends of the oil guide core are respectively connected to the inside of the temporary storage cavity and the inside of the oil storage cotton.
[0008] The outer casing is equipped with a heating structure for heating and atomizing e-liquid.
[0009] Preferably, the temporary storage cavity is formed by the outer wall of the oil storage body, the bottom surface of the sealing ring, the inner wall of the outer cover, and the top surface of the bottom cover, and the outer side of the oil storage cotton and the inner side of the isolation tube are in close contact with each other.
[0010] Preferably, the upper end of the isolation tube is provided with annularly distributed rectangular grooves, and the oil guide core passes through the rectangular grooves and connects the inside of the oil storage cotton with the temporary storage cavity. The bottom outer side of the outer cover is provided with equally distributed oil inlet holes, and the oil inlet holes are connected to the inside of the temporary storage cavity.
[0011] Preferably, a support tube is fixedly connected to the inner side of the upper end of the outer cover, and the outer sides of the oil-absorbing cotton and the oil-storing cotton are in close contact with each other, and the lower bottom of the support tube is designed with a hollow structure.
[0012] Preferably, the sealing ring has two symmetrically distributed air guide tubes inside, and the two ends of the air guide tubes are respectively connected to the interior of the temporary storage cavity and the oil-absorbing cotton.
[0013] Preferably, the heating structure includes a clip fixedly connected to the middle of the bottom cover, and a cotton-filled swab is fixedly connected inside the clip, with the cotton-filled swab extending to the top of the outer cover.
[0014] Preferably, an oil-guiding cotton is fixedly connected to the outside of the cotton-wrapping rod, and the oil-guiding cotton is located between the outside and inside of the support tube. The outer side of the oil-guiding cotton is fitted with the hollowed-out part at the bottom of the support tube and the temporary storage cavity. A heating mesh is installed between the outside of the support tube and the oil-guiding cotton.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This is a leak-proof atomizing core structure based on self-venting negative pressure isolation. By setting a temporary storage chamber between the oil storage tank and the oil storage cotton, and configuring an air guide pipe on the sealing ring, the temporary storage chamber can be connected to the outside atmosphere. This ensures that the air pressure inside the temporary storage chamber remains stable and avoids the phenomenon of increased negative pressure due to reduced oil. It can effectively prevent excessive oil intake and oil leakage caused by negative pressure.
[0017] The improved structure effectively solves the problem of continuous oil leakage caused by increased negative pressure when the oil level in the traditional oil storage tank decreases. The oil is introduced into the temporary storage chamber through the oil inlet and then transferred to the oil storage cotton through the oil guide rope. Compared with the traditional structure, the amount of oil introduced can be controlled more precisely, thereby significantly reducing the possibility of excessive oil intake and leakage, and improving the safety and reliability of the atomizing device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1: Please refer to Figure 1 - Figure 6This utility model provides the following technical solution: a leak-proof atomizing core structure based on self-exhausting negative pressure isolation, including an outer cover 1, a bottom cover 2 fixedly connected to the bottom of the outer cover 1, and a sealing ring 3 fixedly connected to the middle of the outer cover 1; an oil storage cotton 4 fixedly connected to the top of the bottom cover 2, and the outer side of the oil storage cotton 4 and the inner side of the sealing ring 3 are fitted together to form a sealing structure; a temporary storage cavity 5 is provided inside the outer cover 1, and an isolation tube 6 is provided between the temporary storage cavity 5 and the oil storage cotton 4; an oil guide core 8 is installed inside the isolation tube 6, and the two ends of the oil guide core 8 are respectively connected to the inside of the temporary storage cavity 5 and the inside of the oil storage cotton 4; a heating structure for heating and atomizing e-liquid is installed inside the outer cover 1; the temporary storage cavity 5 consists of the outer wall of the oil storage body 4 and the bottom surface of the sealing ring 3. The outer cover 1 is formed by the inner wall and the top surface of the bottom cover 2, and the outer side of the oil storage cotton 4 and the inner side of the isolation tube 6 are in contact with each other; the upper end of the isolation tube 6 is provided with annularly distributed rectangular grooves 7, and the oil guide core 8 passes through the rectangular grooves 7 and connects the inside of the oil storage cotton 4 and the temporary storage cavity 5. The outer bottom of the outer cover 1 is provided with equidistantly distributed oil inlet holes 9, and the oil inlet holes 9 and the inside of the temporary storage cavity 5 are in communication; the upper inner side of the outer cover 1 is fixedly connected with a support tube 12, and the oil absorbent cotton 10 and the outer side of the oil storage cotton 4 are in contact with each other, and the lower bottom of the support tube 12 is provided with a hollow structure; the sealing ring 3 is provided with two symmetrically distributed air guide tubes 11, and the two ends of the air guide tubes 11 are respectively connected to the inside of the temporary storage cavity 5 and the oil absorbent cotton 10.
[0027] During the use of the atomizing core, the outer cover 1 is installed inside the oil tank. The oil inside the oil tank will enter the temporary storage chamber 5 through the oil inlet 9. When the oil enters the temporary storage chamber 5, the air inside the temporary storage chamber will be discharged through the air guide tube 11, thereby ensuring that the air pressure inside the temporary storage chamber 5 does not change, and avoiding excessive oil intake or oil leakage.
[0028] The oil is temporarily stored in the temporary storage chamber 5. The two ends of the oil guide core 8 are connected to the oil storage cotton 4 and the inside of the temporary storage chamber 5, respectively. Thus, the oil guide core 8 guides the oil inside the temporary storage chamber 5 into the oil storage cotton 4. During this process, the oil storage cotton 4 will effectively store the oil. And because the oil storage cotton and the oil guide cotton 15 are in contact with each other, the oil guide cotton 15 will absorb the oil inside the oil storage cotton 4. At this time, when the heating structure is energized, it will heat the oil and generate smoke.
[0029] When there is too much oil in the oil tank and it is higher than the rectangular groove 7, in addition to the oil guide core 8 guiding the oil into the oil storage cotton 4, the oil can also directly enter the oil storage cotton 4 through the rectangular groove 7. However, when there is too little oil in the oil tank and it is lower than the rectangular groove 7, the oil level in the temporary storage cavity 5 will be lower than the rectangular groove, and negative pressure will be generated inside the oil tank, causing the oil to be guided into the oil storage cotton 4 only through the oil guide core 8.
[0030] Since the oil guide core 8 and the heating mesh are at the same height, when the temperature of the heating mesh rises, it will heat the oil guide core 8, thereby increasing the oil guiding speed of the oil guide core 8 and making the atomization process more efficient.
[0031] Example 2: Based on Example 1, a heating structure is also disclosed, the specific structure of which is as follows: The heating structure includes a clip 13 fixedly connected to the middle of the bottom cover 2, and a cotton-wrapping rod 14 is fixedly connected inside the clip 13, and the cotton-wrapping rod 14 extends to the top of the outer cover 1; an oil-guiding cotton 15 is fixedly connected to the outside of the cotton-wrapping rod 14, and the oil-guiding cotton 15 is located between the outside of the support tube 12 and the inside of the support tube 12. The outside of the oil-guiding cotton 15 fits against the hollow part at the bottom of the support tube 12 and the temporary storage cavity 5, and a heating mesh is installed between the outside of the support tube 12 and the oil-guiding cotton 15.
[0032] During the use of the atomizing core, the heating mesh in the heating structure is powered on and begins to heat up. At this time, the oil-guiding cotton 15 will absorb the oil inside the oil-collecting cotton 4, so that the oil stored in the oil-collecting cotton 4 is transferred to the area where the heating mesh is located through the oil-guiding cotton 15. During the heating process, the heating mesh can heat the adjacent oil-guiding cotton 15, thereby increasing the internal temperature of the oil-guiding cotton 15, causing the oil inside to evaporate and form smoke.
[0033] Once the smoke is formed, it will move upward along the internal structure of the support tube 12 and eventually be discharged through the top of the outer cover 1, forming a clear atomization effect. In this process, the oil-guiding cotton 15, as a heat conduction material, ensures that the oil can be heated quickly, while its wide contact area provides good conditions for the evaporation of the oil.
