Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, specifically to a dual-filler electronic cigarette. Background Technology

[0002] Electronic cigarettes, as a substitute for traditional cigarettes, are products that use atomization and other methods to turn e-liquid into vapor for users to inhale.

[0003] The prior art provides a dual-tank electronic cigarette (announcement number CN220192196U). This utility model includes a shell with a cavity inside. The cavity is divided into a first tank and a second tank by a partition. The first tank is located above the second tank and has a larger volume than the second tank. The partition is provided with a one-way valve that allows liquid to flow only from the first tank to the second tank. The shell is provided with a mouthpiece. The first tank has a sleeve communicating with the mouthpiece, and the second tank has an atomizing core communicating with the sleeve.

[0004] The aforementioned dual-tank e-cigarettes have a poor sealing effect on the tanks using only a sealing seat during actual use. When the e-cigarette is dropped or bumped, the e-liquid is prone to leaking from the sealing seat, affecting its use and potentially damaging the device. Therefore, we need to propose a dual-tank e-cigarette. Utility Model Content

[0005] The purpose of this invention is to provide a dual-tank electronic cigarette that improves the sealing effect of the tank by sealing the outer shell and the base multiple times, effectively reducing the risk of e-liquid leakage when the electronic cigarette is dropped or bumped, significantly improving the sealing between the base and the outer shell, enhancing the user experience, and reducing leakage problems, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention utilizes a design incorporating a push ring, sealing gasket, sealing ring, and inflation ring. The push ring and sealing gasket on the base allow the push ring to engage with the fixing ring to press against the sealing gasket when the base is installed inside the outer shell, providing an initial seal between the base and the outer shell. Multiple sealing rings on the base surface further seal the area, enhancing the overall sealing effect. Additionally, the inflation ring inflates to seal the area between the base and the outer shell. This multiple sealing process improves the sealing of the e-liquid tank, effectively reducing the risk of e-liquid leakage when the e-cigarette is dropped or bumped. This significantly enhances the seal between the base and the outer shell, improving the user experience and reducing e-liquid leakage. Attached Figure Description

[0032] It should be noted that by setting the second one-way valve 17, the inflation device is used to inflate the connecting channel 16 through the second one-way valve 17, so that the gas can be delivered to the inflation ring 15 through the connecting channel 16, so that the inflation ring 15 can be inflated and sealed between the base 2 and the outer shell 1. The first one-way valve 10 and the second one-way valve 17 are both existing mature technologies, and will not be described in detail in this application.

[0033] In an optional embodiment: an air inlet pipe 3 is fixedly installed inside the base 2, a positioning seat 4 is fixedly installed on the top of the air inlet pipe 3, an atomizing core 5 is provided on the top of the positioning seat 4, and a delivery pipe 6 is connected to the inside of the outer shell 1, with the delivery pipe 6 positioned above the atomizing core 5.

[0034] It should be noted that the atomizing core 5 atomizes the e-liquid, allowing the vapor to be transported through the delivery tube 6.

[0035] In an optional embodiment: the atomizing core 5 includes an oil-guiding cotton 501, an oil-absorbing cotton 502, and a heating wire 503. The oil-guiding cotton 501 and the oil-absorbing cotton 502 are both sleeved on the top of the positioning seat 4. The surface of the oil-absorbing cotton 502 is in contact with the inner wall of the oil-guiding cotton 501. The heating wire 503 is disposed on the top of the positioning seat 4, and the positioning seat 4 is in contact with the inner wall of the oil-absorbing cotton 502.

[0039] In an optional embodiment: a protective sleeve 20 is provided on the suction nozzle 18, and an extension tube 21 is fixedly connected to the protective sleeve 20 and inserted into the suction nozzle 18.

[0040] It should be noted that the protective cover 20 forms a physical barrier on the mouthpiece 18, which can effectively prevent residues (such as saliva) from directly contacting the mouthpiece after use. This is especially important for e-cigarettes shared by multiple people, as it can greatly reduce the risk of cross-infection and keep the mouthpiece clean and hygienic. In addition, it can also play a certain protective role in preventing the mouthpiece from being accidentally bumped or contaminated.

[0041] In an optional embodiment: a partition 7 is fixedly connected to the surface of the conveying pipe 6, the side of the partition 7 is fixedly connected to the inner wall of the outer shell 1, the interior of the outer shell 1 is divided into a first oil tank 8 and a second oil tank 9 by the partition 7, and a first one-way valve 10 is provided on the partition 7.

[0042] It should be noted that the first one-way valve 10 prevents the e-liquid in the second oil tank 9 from flowing back into the first oil tank 8.

[0043] In an optional embodiment, the cigarette holder 23 has multiple sets of air inlets 19 for air intake.

[0044] It should be noted that when using an electronic cigarette, air enters the air intake pipe 3 through the air intake 19.

[0045] In actual use, during the smoking process, the e-liquid in the second oil tank 9 enters the oil-guiding cotton 501 and oil-absorbing cotton 502. When the heating wire 503 works and heats up, it can atomize the e-liquid absorbed by the oil-absorbing cotton 502. The atomized smoke is transported through the delivery pipe 6 and the mouthpiece 18. The e-liquid in the first oil tank 8 can enter the second oil tank 9 through the first one-way valve 10, supplying oil to the second oil tank 9 so that the e-liquid in the second oil tank 9 can be in a full oil state.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
