Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, specifically to an oil-proof electronic atomizer. Background Technology

[0002] Electronic atomizers, also commonly known as e-cigarettes, are devices that use a battery to power an atomizer coil to heat e-liquid and turn it into vapor, simulating the smoking experience. The working principle of an electronic atomizer is based on the process of electrically heating a liquid to vaporize it. It typically consists of three main parts: a battery, an atomizer, and a cartridge. The battery provides power to the atomizer, and the heating element inside the atomizer heats the liquid in the cartridge to its evaporation point, forming a vaporous aerosol. Users inhale this aerosol to simulate the smoking process. However, current atomizers are not convenient for users to refill; furthermore, current atomizers lack filters, resulting in a generally mediocre flavor.

[0003] In the prior art, such as the announcement number CN214854336U, a leak-proof e-liquid electronic cigarette atomizer is proposed. This technical solution applies to the field of electronic cigarette technology and provides a leak-proof e-liquid electronic cigarette atomizer, including a body assembly, which includes an outer cylinder; an inner cylinder is provided inside the outer cylinder, and the outer cylinder and the inner cylinder are fixedly connected. The outer wall of the inner cylinder has a liquid inlet hole; a cover is provided on the top of the outer cylinder, and an insertion tube is connected to the center of the cover, extending into the inner cylinder; an atomizing core is installed on the inner wall of the insertion tube, and oil-absorbing cotton is installed at the bottom of the atomizing core; an air intake tube is provided on the top of the cover; when the user needs to refill the device, an upward pulling force is applied to the cover through the air intake tube to disengage the key on the cover from the slot, and the cover can be removed; then e-liquid is filled between the outer cylinder and the inner cylinder, and a downward pushing force is applied to the cover through the air intake tube again to make the key on the cover enter the slot, making the device easy to disassemble for adding e-liquid;

[0004] However, existing electronic cigarette technology requires disassembling the cover and the e-cigarette shell when adding e-liquid. The cover and the e-cigarette shell are only fixed by frictional resistance. Therefore, after repeated use, the connection may become loose, resulting in a limited lifespan and the possibility of leakage.

[0005] To address the aforementioned issues, this application proposes an oil-leakage-proof electronic atomizer. Utility Model Content

[0006] This utility model aims to provide a leak-proof electronic atomizer, mainly to solve the problem that when adding e-liquid to existing electronic cigarettes, the cover and the e-cigarette shell need to be disassembled. The cover and the e-cigarette shell are only fixed by frictional resistance, which may result in a loose connection, limited service life, and the possibility of leakage.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] An oil-proof electronic atomizer includes an electronic cigarette housing, a top cover detachably connected to the top of the electronic cigarette housing, a sealing ring fixedly connected to the top of the electronic cigarette housing, a limiting component for fixing the top cover on the electronic cigarette housing, an installation cylinder detachably connected to the top of the top cover, a filter tip fixedly connected to the top of the installation cylinder, and a filter layer fixedly connected to the top of the inner wall of the installation cylinder.

[0009] The working principle and beneficial effects of this utility model:

[0010] Working principle: When this electronic cigarette is in use, (the liquid in the oil reservoir flows into the inner cylinder through the inlet hole, where the absorbent cotton absorbs the smoke, thus providing it to the atomizer for atomization. A sealing ring is used to improve the device's sealing performance and prevent e-liquid leakage). (The part in parentheses refers to existing technology, which is not elaborated upon in this application.) When the user inhales smoke through the filter, the filter layer filters the smoke, ensuring it is free of impurities and improving the richness of the flavor. When e-liquid needs to be added, the top cover can be removed from the electronic cigarette housing after releasing the limiting component. E-liquid can then be added to the electronic cigarette housing. After adding the e-liquid, the top cover is fixed back onto the electronic cigarette housing by the limiting component, and the electronic cigarette can then be used normally.

[0011] Beneficial effects: The top cover is fixed to the e-cigarette housing by the limiting component, which not only makes it easier to install and remove the top cover, but also makes the connection between the top cover and the e-cigarette housing more secure, thereby further preventing oil leakage. The top cover is detachably connected to the mounting cylinder, which is equipped with a filter, so that users can easily replace the filter regularly.

[0012] Preferably, the limiting component includes multiple sliding cavities inside the electronic cigarette housing, arranged in a circumferential array at equal intervals within the housing. Each cavity has a sliding plate slidably connected to it. A spring is fixedly connected to the bottom of one side of each sliding plate, and the other end of the spring is fixedly connected to the inner wall of the cavity. A limiting block is fixedly connected to the top of the sliding plate away from the spring, and a wedge block is fixedly connected to the bottom of the sliding plate away from the spring. Both the limiting block and the wedge block extend out of the electronic cigarette housing and are slidably connected to it. The inner wall of the top cover has a limiting groove that matches the limiting block. When e-liquid needs to be added... Simultaneously press the multiple wedge-shaped blocks on the e-cigarette housing to cause the limiting blocks to slide into the sliding cavity via the moving plate. Once the limiting blocks are all disengaged from the limiting groove inside the top cover, the top cover can be removed from the e-cigarette housing. Then, e-liquid can be added into the e-cigarette housing. After the e-liquid is added, install the top cover onto the e-cigarette housing, release the wedge-shaped blocks, and the moving plate will move the limiting blocks outward under the action of the spring inside the sliding cavity, causing them to engage with the limiting groove. This will fix the top cover onto the e-cigarette housing, making the installation and removal of the top cover more convenient and the connection between the top cover and the e-cigarette housing more secure.

[0013] Preferably, a fixing cylinder that matches the inner wall of the mounting cylinder is fixedly connected to the top of the top cover, and a rubber pad is fixedly connected to the bottom of the inner wall of the mounting cylinder. When the filter becomes contaminated or damaged after prolonged use of the electronic cigarette, the mounting cylinder can be pulled upwards to remove it from the top cover. Then, the mounting cylinder with the new filter can be taken out and its bottom can be placed on the fixing cylinder. The rubber pad on the inner wall of the mounting cylinder ensures high sealing and stability after installation, thereby effectively guaranteeing the normal use of the electronic cigarette.

[0014] Preferably, the outer wall of the electronic cigarette casing is threaded with a threaded sleeve. The corner at the top of the inner wall of the threaded sleeve is chamfered. When e-liquid needs to be added, the threaded sleeve is rotated to move it upward. As the threaded sleeve moves upward, the top of the inner wall of the threaded sleeve will press the inclined surface of the wedge block, causing it to slide into the sliding cavity through the moving plate. This eliminates the need for manual pressing of the wedge block to move it, making the disassembly and assembly of the top cover more convenient.

[0015] Preferably, the inclined surfaces of the wedge-shaped block extending from the bottom of the electronic cigarette housing are rotatably connected with ball bearings. When the threaded sleeve is rotated to move it upward, the top of the inner wall of the threaded sleeve will contact the inclined surface of the wedge-shaped block and push the wedge-shaped block to move. The ball bearings on the wedge-shaped block can effectively reduce the friction between the inner wall of the threaded sleeve and the wedge-shaped block, making it easier and less strenuous for the user to disassemble and assemble the top cover.

[0016] Preferably, the corner at the top of the outer wall of the fixed cylinder is chamfered. By setting the corner at the top of the outer wall of the fixed cylinder as chamfered, the installation of the mounting cylinder can be made more convenient.

[0017] Preferably, the outer wall of the threaded sleeve is fitted with a rubber sleeve, and the outer wall of the rubber sleeve has anti-slip texture. The rubber sleeve on the outer wall of the threaded sleeve makes it more comfortable for the user to hold and rotate the threaded sleeve. The anti-slip texture on the outer wall of the rubber sleeve can effectively increase the friction between the user's hand and the threaded sleeve, thereby effectively preventing the user's hand from slipping when rotating the threaded sleeve.

[0023] 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.

[0024] Please see Figure 1-4An oil-proof electronic atomizer includes an electronic cigarette housing 1, a top cover 2 detachably connected to the top of the electronic cigarette housing 1, and a sealing ring 5 fixedly connected to the top of the electronic cigarette housing 1. The sealing ring 5 improves the sealing performance of the top cover 2 after installation. A limiting component for fixing the top cover 2 is provided on the electronic cigarette housing 1. The top cover 2 is fixed to the electronic cigarette housing 1 by the limiting component, which not only makes the installation and removal of the top cover 2 more convenient but also makes the connection between the top cover 2 and the electronic cigarette housing 1 more secure. A mounting cylinder 3 is detachably connected to the top of the top cover 2, and a filter 17 is fixedly connected to the top of the mounting cylinder 3. A fixing cylinder 12, which matches the inner wall of the mounting cylinder 3, is fixedly connected to the top of the top cover 2. The corner of the top of the outer wall of the fixing cylinder 12... The installation tube 3 is chamfered, which makes the installation easier. A rubber pad 13 is fixedly connected to the bottom of the inner wall of the installation tube 3. When the filter 17 becomes contaminated or damaged after long-term use of the e-cigarette, the installation tube 3 can be pulled upward to remove it from the top cover 2. Then, the installation tube 3 with the new filter 17 is taken out and its bottom is put on the fixing tube 12. The rubber pad 13 on the inner wall of the installation tube 3 ensures high sealing and stability after installation, thus effectively ensuring the normal use of the e-cigarette. A filter layer 4 is fixedly connected to the top of the inner wall of the installation tube 3. When the user inhales smoke through the filter 17, the filter layer 4 filters the smoke to ensure that there are no foreign objects in the smoke and improves the mellowness of the taste.

[0025] like Figure 2 and Figure 4As shown, the limiting component includes multiple sliding cavities 6 inside the electronic cigarette housing 1, and the sliding cavities 6 are evenly distributed in a circular array inside the electronic cigarette housing 1. A movable plate 7 is slidably connected inside each sliding cavity 6. A spring 8 is fixedly connected to the bottom of one side of the movable plate 7, and the other end of the spring 8 is fixedly connected to the inner wall of the sliding cavity 6. A limiting block 9 is fixedly connected to the top of the movable plate 7 away from the spring 8, and a wedge block 11 is fixedly connected to the bottom of the movable plate 7 away from the spring 8. Both the limiting block 9 and the wedge block 11 extend out of the electronic cigarette housing 1, and both are slidably connected to the electronic cigarette housing 1. A ball bearing 15 is rotatably connected to the inclined surface of the bottom side of the wedge block 11 extending out of the electronic cigarette housing 1. A limiting groove 10 matching the limiting block 9 is opened on the inner wall of the top cover 2. A threaded sleeve 14 is threadedly connected to the outer wall of the electronic cigarette housing 1. The corner at the top of the inner wall of the threaded sleeve 14 is chamfered. The outer wall is fitted with a rubber sleeve 16, and the outer wall of the rubber sleeve 16 has anti-slip texture. When e-liquid needs to be added, the threaded sleeve 14 is rotated to move it upward. As the threaded sleeve 14 moves upward, the top of the inner wall of the threaded sleeve 14 will press the inclined surface of the wedge block 11, causing it to slide into the sliding cavity 6 through the moving plate 7 and the limiting block 9. When the limiting block 9 is disengaged from the limiting groove 10 inside the top cover 2, the top cover 2 can be removed from the electronic cigarette housing 1. Then, e-liquid can be added into the electronic cigarette housing 1. After the e-liquid is added, the top cover 2 is installed on the electronic cigarette housing 1. The threaded sleeve 14 is rotated in the opposite direction to move it downward. The moving plate 7 will drive the limiting block 9 to move outward under the action of the spring 8 inside the sliding cavity 6 and make it engage with the limiting groove 10, thus fixing the top cover 2 on the electronic cigarette housing 1. This not only makes the installation and removal of the top cover 2 more convenient, but also makes the connection between the top cover 2 and the electronic cigarette housing 1 more secure.

[0026] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0027] When the electronic cigarette is in use, (the liquid in the oil storage chamber flows into the inner cylinder through the liquid inlet, allowing the oil-absorbing cotton to absorb the smoke, thus providing it to the atomizer for atomization. By setting a sealing ring, the sealing performance of this device is improved, preventing e-liquid leakage). The part in parentheses refers to prior art, which is not described in detail in this application. When the user inhales smoke through the filter 17, the filter layer 4 filters the smoke to ensure that there are no foreign objects in the smoke, improving the richness of the flavor. When e-liquid needs to be added, the threaded sleeve 14 is rotated to move it upward. As the threaded sleeve 14 moves upward, the top of the inner wall of the threaded sleeve 14 will press the inclined surface of the wedge block 11, causing it to slide into the sliding cavity 6 through the moving plate 7 and the limiting block 9. When the limiting block 9 is completely disengaged from the limiting groove 10 inside the top cover 2, the top cover 2 can be removed from the electronic cigarette shell. After removing the top cover 1, e-liquid can be added to the inside of the e-cigarette housing 1. After adding the e-liquid, the top cover 2 is installed on the e-cigarette housing 1. The threaded sleeve 14 is rotated in the opposite direction to move it downward. The moving plate 7 will be driven by the spring 8 inside the sliding cavity 6 to move the limiting block 9 outward and engage with the limiting groove 10, thus fixing the top cover 2 on the e-cigarette housing 1. The e-cigarette can then be used normally. After the e-cigarette has been used for a long time, if the filter 17 becomes contaminated or damaged, the mounting cylinder 3 can be pulled upward to remove it from the top cover 2. Then, the mounting cylinder 3 with the new filter 17 is taken out and its bottom is placed on the fixing cylinder 12. The rubber gasket 13 set on the inner wall of the mounting cylinder 3 ensures that the mounting cylinder 3 has high sealing and stability after installation, thus effectively ensuring the normal use of the e-cigarette.
