Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, specifically to a large-capacity oil cup electronic cigarette with a leak-proof structure. Background Technology
[0002] An electronic cigarette is an electronic product that mimics the effects of a cigarette. It uses an atomizing component to vaporize a liquid containing nicotine for the user to inhale. Electronic cigarettes typically consist of a cartridge and a device. The cartridge contains a reservoir to store the nicotine, and the atomizing component, powered by a battery within the device, transforms the liquid nicotine in the cartridge into vapor, giving the user a sensation similar to smoking, allowing them to "exhale clouds of smoke."
[0003] With the development of e-cigarettes, in order to meet the needs of different users, large-capacity e-cigarette cups have emerged, thus satisfying users' requirements for products with a longer service life. However, due to the large-capacity e-cigarette cup, the amount of condensate produced also increases, leading to the possibility of leakage. This fails to meet the user experience and is detrimental to improving the product's competitiveness. Utility Model Content
[0004] To address the problems in the existing technology, this utility model provides a large-capacity e-liquid cup electronic cigarette with a leak-proof structure, which solves the problem of easy leakage in existing electronic cigarettes with large-capacity e-liquid.

[0009] This utility model is further improved by providing two atomizing chambers inside the atomizing installation tube, and also by providing two atomizing core components, two oil storage bottles, and two oil guiding channels. The number of the lower sealing silicone, the first oil suction component, the electrode adapter, the second oil suction component, and the air inlet on the bottom cover of the cartridge are also two. The two atomizing core components are respectively set in the corresponding atomizing chambers, and the atomizing core components, oil storage bottles, and oil guiding channels are matched one by one.
[0010] This utility model is further improved. The electrode adapter includes an adapter circuit board, a negative electrode, and two positive electrodes. The atomizing core assembly is provided with a positive connection pin and a negative connection pin. The adapter circuit board is provided with a positive connection hole and a negative connection hole that cooperate with the positive electrode and the negative electrode.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0018] like Figure 1-4 As shown, this utility model discloses a large-capacity e-cigarette with a leak-proof structure, comprising a cartridge 1 and a device 2.

An atomizing core assembly 5 is provided inside the atomizing mounting cylinder 31. The e-liquid in the storage bottle 4 can flow into the atomizing core assembly through the e-liquid channel 321. Component 5, the atomizing core assembly 5 is provided with an atomizing channel 50, and the lower sealing cover assembly includes, from top to bottom, a lower sealing silicone 6, a first oil-absorbing component 7, an electrode adapter, a second oil-absorbing component, and a cartridge bottom cover 13. The lower sealing silicone 6, the first oil-absorbing component 7, the electrode adapter, the second oil-absorbing component, and the cartridge bottom cover 13 are all provided with air inlets 81 that cooperate with the atomizing channel 50. The side of the air inlet 81 of the electrode adapter is provided with a first liquid-absorbing hole 82, and the first liquid-absorbing hole 82 is connected to the air inlet 81 of the electrode adapter. The liquid of the first oil-absorbing component 7 can flow directly to the second oil-absorbing component through the first liquid-absorbing hole 82.
[0019] The cooperation of the first oil suction component 7 and the second oil suction component can effectively increase the total amount of condensate collected. Furthermore, with the setting of the first liquid suction port 82, when the amount collected by the first oil suction component 7 at the air inlet exceeds the capacity range, it can be directly transferred to the second oil suction component for collection, preventing leakage from the product through the air inlet 81.

[0022] The second oil-absorbing component includes an upper oil-absorbing cotton 11 and a lower oil-absorbing cotton 12.

The lower oil-absorbing cotton 12 is provided with a clearance positioning hole 121 that cooperates with the electrode mounting groove 131 and the positioning post 132.
[0023] By combining the upper oil-absorbing cotton 11 and the lower oil-absorbing cotton 12, the internal space of the cartridge base 32 can be effectively utilized to increase the amount of condensate collected.

The third oil-absorbing vent 111 can cooperate with the first liquid-absorbing vent 82 or the second liquid-absorbing vent 83 so that the liquid of the first oil-absorbing component 7 can flow directly onto the lower oil-absorbing cotton 12.
[0025] By setting the third oil absorption vent 111, when the amount of liquid collected by the first oil absorption component 7 at the air inlet exceeds its capacity, the excess liquid is first transferred to the lower oil absorption cotton 12, and then the upper oil absorption cotton 11 works in conjunction with the lower oil absorption cotton 12 to absorb the liquid, effectively improving the utilization rate of the lower oil absorption cotton 12.
[0026] The atomizing installation tube 31 has two atomizing chambers. There are also two atomizing core components 5, two oil storage bottles 4, and two oil guiding channels 321.

The atomizing core components 5, oil storage bottles 4, and oil guiding channels 321 are matched one by one.
[0027] The integration of multiple e-liquids can be achieved through the cooperation of two atomizing core components 5.
[0028] The electrode adapter includes an adapter circuit board 8, a negative electrode 9, and two positive electrodes 10. The atomizing core assembly 5 is provided with a positive connection pin and a negative connection pin. The adapter circuit board 8 is provided with a positive connection hole 84 and a negative connection hole 85 that mate with the positive electrode 10 and the negative electrode 9.

The positive electrode 10 is electrically connected to the positive connection pin in the positive connection hole 84, and the negative electrode 9 is electrically connected to the negative connection pin in the negative connection hole 85.
[0029] The adapter circuit board 8 is only used to make electrical connections between the positive electrode 10 and the negative electrode 9 and the positive and negative pins, respectively. It does not contain any components and can ensure a certain degree of high temperature resistance.
[0030] The negative electrode 9 and two positive electrodes 10 are disposed in the negative connection hole 85 and the positive connection hole 84, which enables the positive electrode 10 and the negative electrode 9 to be electrically connected to the positive connection pin and the negative connection pin respectively during installation, thereby improving the stability of the positive connection pin and the negative connection pin.
[0031] The positive electrode 10 is provided with a limiting boss 101 that mates with the positive electrode connection hole 84. The cross-sectional area of the limiting boss 101 is larger than the area of the positive electrode connection hole 84.
[0032] The limiting boss 101 can support the adapter circuit board 8.
