Description

Technical Field

[0001] This utility model relates to the technical field of electronic atomization devices, specifically a pre-filled oil fume cartridge and an electronic atomization device that prevents oil leakage. Background Technology

[0002] Electronic vaporizers are electronic products that mimic cigarettes, producing smoke, taste, and sensations similar to cigarettes. They generate vapor by heating and vaporizing e-liquid made from chemicals and various flavorings. By controlling the composition of the e-liquid, the nicotine content can be controlled. Therefore, e-cigarettes, primarily used for smoking cessation and as a substitute for cigarettes, have been rapidly promoted and used.

[0003] In related technologies, electronic atomizing devices include cartridges and main units. However, during the production process of electronic atomizing devices, the oil reservoir in the cartridge is first filled with oil. However, the atomizer in the cartridge is usually in direct contact with the atomized liquid in the oil reservoir. Due to bumps or vibrations during transportation, the atomized liquid in the oil reservoir may leak out of the cartridge and flow into the main unit, causing damage to the microphone.

[0004] Therefore, existing technologies need to be improved. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application proposes a pre-filled oil fume cartridge and an electronic atomizing device to prevent oil leakage.

[0006] Firstly, the pre-filled fume extractor for preventing oil leakage provided in this application adopts the following technical solution: A leak-proof pre-filled e-cigarette cartridge includes an oil storage tank and a base. The oil storage tank includes a hollow shell, a mounting base, and an oil filling activation tube. The shell has an opening at its lower side, and a limiting tube is provided on the side of the shell away from the opening. The mounting base is sealed to the opening of the shell and has a mounting hole. The two end walls of the oil filling activation tube are respectively sealed to the mounting hole and the inner wall of the limiting tube. A top ring is provided on the inner wall of the end of the oil filling activation tube near the limiting tube. The limiting tube provides space at the upper end of the oil filling activation tube for the tube to move. When the oil filling activation tube moves to its uppermost position, it disengages from the mounting base. An atomizer is provided on the base and is inserted into the oil filling activation tube to move it.

[0007] Preferably, the oil injection activation tube has sealing grooves on the outer walls at both ends, and sealing rings are provided in the sealing grooves. The two sealing rings abut against the inner wall of the limiting tube and the inner wall of the mounting hole, respectively.

[0008] Preferably, a limiting ring is provided on the inner wall of the mounting hole, and the side of the limiting ring near the limiting tube is used to abut against the oil injection activation tube.

[0009] Preferably, the base is provided with an installation ring, the inner wall of which is abutted against a steel pipe, and a sealing ring is also provided inside the installation ring. The sealing ring is in close contact with the inner wall of the steel pipe so that the steel pipe is installed in the installation ring. The atomizer is disposed in the steel pipe, and the outer side of the atomizer is wrapped with oil storage cotton. The outer wall of the oil storage cotton is in contact with the inside of the steel pipe. The steel pipe is provided with an oil inlet hole for introducing the atomized liquid in the oil storage tank into the atomizer.

[0010] Preferably, the inner wall of the mounting ring is provided with a placement ring, and the side of the placement ring near the oil injection activation pipe is used for placing the steel pipe and the sealing ring.

[0011] Preferably, the housing has an extension at its opening, the extension has a slot, and the base has a locking block on its side, the locking block being used to engage with the slot.

[0012] Preferably, the card block has a guide surface on the side near the atomizer.

[0013] Preferably, a sealing ring is provided at the opening on the side of the steel pipe away from the base, and the sealing ring is used to seal the space between the atomizer and the steel pipe.

[0014] Preferably, the base has a receiving cavity, the bottom of the receiving cavity has an air inlet communicating with the atomizer, and a baffle cylinder is provided in the receiving cavity, the baffle cylinder communicating with the air inlet.

[0015] Secondly, this application provides an electronic atomizing device using the following technical solution: An electronic atomizing device includes a cartridge and a main unit.

[0016] In summary, this application includes the following beneficial technical effects: When using the e-cigarette, first assemble the e-liquid tank and the base. Insert the atomizer from the base into the e-liquid activation tube through the mounting hole on the mounting base. As the atomizer is inserted, it will contact the top ring of the activation tube. Continue pushing the base until it is installed on the e-liquid tank. The activation tube will then be pushed upwards to its highest point, disengaging its bottom edge from the inner wall of the mounting hole. At this point, the e-liquid in the tank will flow into the atomizer through the gap between the activation tube and the mounting base, activating the cartridge. This design isolates the e-liquid in the tank during production and transportation, allowing the tank and base to be transported separately. This reduces leakage of e-liquid from the cartridge due to bumps or vibrations, preventing microphone damage and significantly improving the user experience. Attached Figure Description

Detailed Implementation

[0020] 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 scope of protection of the present utility model.

[0021] This application discloses a pre-filled fume cartridge that prevents oil leakage.

[0022] Reference Figures 1 to 6 A leak-proof pre-filled fume cartridge includes an oil storage tank 2 and a base 3. Specifically, the oil storage tank 2 includes a shell 21, a mounting base 22, and an oil filling activation tube 23. The shell 21 is hollow inside, with an opening on its lower side. A limiting tube 211 is provided on the side of the shell 21 away from its opening, and the limiting tube 211 is connected to the mouthpiece on the shell 21. The side of the mounting base 22 is tightly abutted against the side wall of the opening of the shell 21. The mounting base 22 is provided with a mounting hole 221, through which the mounting hole 221... The cross-section of the oil injection activation tube 23 is circular when viewed from one side of the orifice. The mounting hole 221 and the limiting tube 211 are coaxially aligned. The outer plates at both ends of the oil injection activation tube 23 are tightly sealed against the inner walls of the limiting tube 211 and the mounting hole 221, respectively. A space is provided on the upper side of the limiting tube 211 for the oil injection activation tube 23 to move upwards along the limiting tube 211. When the oil injection activation tube 23 moves to its highest point, its lower end separates from the mounting base 22 to allow the atomizing liquid to flow out. A top ring 231 is provided on the inner wall of the e-liquid activation tube 23. The top ring 231 is coaxially arranged with the e-liquid activation tube 23 and is located at the opening of the e-liquid activation tube 23 near the limiting tube 211. The top ring 231 is used to abut against the smoke outlet channel of the e-liquid cartridge 1. The base 3 is used to connect to the lower opening of the housing 21. An atomizer 4 is provided on the side of the base 3 near the mounting base 22. The atomizer 4 is used to extend into the e-liquid activation tube 23. After the atomizer 4 extends into the e-liquid activation tube 23, it will abut against the e-liquid activation tube 23. The top ring 231 of the base 3 abuts against each other. When the base 3 is installed on the oil storage tank 2, the atomizer 4 will push the oil filling activation tube 23 upward to the highest point. At this time, the atomized liquid in the oil storage tank 2 will flow into the atomizer 4 through the gap between the bottom of the oil filling activation tube 23 and the mounting base 22 to complete the activation of the cartridge 1. This design divides the cartridge 1 into two parts: the oil storage tank 2 and the base 3. The atomized liquid is isolated by the oil filling activation tube 23. When in use, it is activated by inserting the atomizer 4, which can reduce the leakage of atomized liquid.

[0023] In some embodiments, a sealing groove 232 is provided on the outer wall of the oil injection activation tube 23. Two sets of sealing grooves 232 are provided, and the two sets of sealing grooves 232 are respectively provided at both ends of the oil injection activation tube 23. A sealing ring 233 is provided in the sealing groove 232. The outer side of the sealing ring 233 extends out from the groove opening of the sealing groove 232. The two sealing rings 233 abut against the inner wall of the limiting tube 211 and the inner wall of the mounting hole 221, respectively, so that when the e-cigarette cartridge 1 is not activated, the oil injection activation component can stably block the atomizing liquid in the oil storage tank 2.

[0024] In addition, a limiting ring 222 is provided in the mounting hole 221. The limiting ring 222 is coaxially arranged with the mounting hole 221. The upper side of the limiting ring 222 is used to abut against the lower end face of the oil injection activation tube 23 to support the oil injection activation tube 23 and prevent the oil injection activation tube 23 from falling out of the mounting hole 221.

[0025] In some embodiments, a mounting ring 31 is provided on one side of the base 3 near the opening of the housing 21. A steel pipe 5 is provided on the inner wall of the mounting ring 31, and the outer side wall of the lower side of the steel pipe 5 abuts against the inner wall of the mounting ring 31. A sealing ring 32 is also provided inside the mounting ring 31, coaxially arranged with the mounting ring 31, and the outer side wall of the sealing ring 32 tightly abuts against the inner side wall of the steel pipe 5, so that the steel pipe 5 is tightly installed in the mounting ring 31. The atomizer 4 is installed in the steel pipe 5, and an oil inlet 51 is provided on the outer side wall of the steel pipe 5. The oil inlet 51 is distributed circumferentially. When the cartridge 1 is activated by installing it into the oil reservoir 2, the atomizing liquid in the oil reservoir 2 enters the atomizer 4 through the oil inlet 51. At the same time, in order to further prevent oil leakage during use, an oil-guiding cotton 52 is installed in the steel pipe 5. The oil-guiding cotton 52 is ring-shaped and is located between the steel pipe 5 and the atomizer 4. That is, the outer wall of the oil-guiding cotton 52 abuts against the steel pipe 5, and the inner wall abuts against the atomizer 4, so that the atomizing liquid in the oil reservoir 2 enters into the oil-guiding cotton 52 through the oil inlet 51, and then the oil-guiding cotton 52 guides the atomizing liquid into the atomizer 4, thereby realizing the control of the amount of atomizing liquid entering.

[0026] In some embodiments, a placement ring 33 is provided on the inner wall of the mounting ring 31. The placement ring 33 is located on the lower side of the mounting ring 31 and is used to support the steel pipe 5 and the sealing ring 32 to prevent the steel pipe 5 from being misaligned and causing the atomizing liquid to be unable to enter the atomizer 4.

[0027] In some embodiments, the height of the steel pipe 5 is higher than that of the atomizer 4. A sealing ring 53 is provided at the upper opening of the steel pipe 5. The sealing ring 53 is coaxially arranged with the steel pipe 5 and communicates with the outlet end of the atomizer 4. The sealing ring 53 is used to seal the annular space between the atomizer 4 and the steel pipe 5 to prevent the atomized liquid in the oil storage cotton 52 from flowing out of the mouthpiece when the cartridge 1 is inverted. At the same time, the upper side of the sealing ring 53 extends out of the steel pipe 5, and the outer wall of the part of the sealing ring 53 extending out of the steel pipe 5 abuts against the inner wall of the oil filling activation tube 23. Therefore, when the cartridge 1 is inverted, the atomized liquid in the oil storage tank may flow into the gap between the oil filling activation tube 23 and the steel pipe 5. Due to the setting of the sealing ring 53, the gap can be sealed to prevent the atomized liquid from flowing out.

[0028] In some embodiments, the base 3 has a receiving cavity 36 inside, which is connected to the mounting ring 31. An air inlet 37 connected to the atomizer 4 is provided at the bottom of the receiving cavity 36. External air enters the atomizer 4 through the air inlet 37. In order to further prevent the e-liquid cartridge 1 from leaking, a baffle cylinder 38 is provided at the bottom of the receiving cavity 36. The baffle cylinder 38 is annular and integrally provided at the bottom of the receiving cavity 36. The baffle cylinder 38 is located at the edge of the air inlet 37 and is coaxial with the air inlet 37. Through the blocking effect of the outer wall of the baffle cylinder 38, the air inlet is raised so that the atomized liquid falling at the bottom of the receiving cavity 36 cannot flow out directly through the air inlet 37. This can block the atomized liquid and prevent the atomized liquid from flowing out of the e-liquid cartridge 1 directly from the air inlet 37.

[0029] In some embodiments, in order to facilitate the installation of the base 3 and the oil storage tank 2, the housing 21 is provided with an extension 212 at its opening. The extension 212 is annular, and a slot 213 is provided on the inner wall of the extension 212. A block 34 is provided on the side of the base 3. The shape of the block 34 is adapted to the slot 213 so that the block 34 can be inserted into the slot 213, so that the base 3 and the oil storage tank 2 are kept apart as much as possible. At the same time, a guide surface 35 is provided on the side of the block 34 near the steel pipe 5. The guide surface 35 is used to guide the extension 212 to facilitate the installation of the base 3.

[0030] This application also discloses an electronic atomizing device, as shown in the reference. Figures 1 to 6 The electronic atomizing device includes the aforementioned cartridge 1 and main unit 6. The main unit 6 is connected to the cartridge 1 to control the cartridge 1. The electronic atomizing device of this embodiment also has the aforementioned beneficial effects.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
