Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, specifically to a positive and negative electrode connection structure for electronic cigarettes. Background Technology

[0002] An electronic cigarette is an electronic device that mimics the function of a traditional cigarette. It vaporizes a liquid containing nicotine using an atomizer, allowing the user to inhale the vapor. Electronic cigarettes typically consist of a cartridge and a device. The cartridge contains a vaporizer, which is powered by a battery within the device. This vaporizer transforms the liquid nicotine in the cartridge into a vapor, giving the user a sensation similar to smoking, allowing them to "exhale clouds of smoke."

[0003] The current connection method between the e-cigarette device and the cartridge generally uses a one-to-one contact between the positive and negative electrodes and their corresponding pin positions to achieve electrical connection. However, this structure lacks a foolproof design, making it easy for the positive and negative electrodes to be reversed with their corresponding pins. This can lead to malfunctions or product damage, resulting in a poor user experience. Furthermore, the requirement for precise positioning of the positive and negative electrodes during production places high demands on manufacturers, potentially leading to a certain number of defective products and failing to meet their production needs.

[0008] This utility model is further improved by providing an oil storage cavity inside the cartridge body and an oil filling cylinder on the cartridge base. The upper end of the oil filling cylinder is connected to the oil storage cavity, and the lower end of the oil filling cylinder is provided with an oil filling metal plug. The cartridge base is provided with a second pin hole on the side of the oil filling cylinder, and the second pin is set in the second pin hole. The lower end face of the cartridge base is provided with a second wiring groove that cooperates with the second pin.

The second pin is electrically connected to the oil filling metal plug, and the oil filling metal plug is electrically connected to the electrode metal sleeve.

[0009] The present invention is further improved in that the end of the second pin is disposed in the oil filling cylinder, and the oil filling metal plug can press the second pin against the inner wall of the oil filling cylinder.

[0010] This utility model is further improved by having two oil injection cylinders and two oil injection metal plugs, with each of the two oil injection metal plugs matching one of the two oil injection cylinders.

[0011] This utility model is further improved by fitting a lower sealing silicone sleeve onto the cartridge base, which is located inside the cartridge body. A limiting boss is provided on the lower periphery of the cartridge base, which can cooperate with the bottom surface of the cartridge body to position the cartridge base.

[0012] This utility model is further improved by providing a connecting buckle on the outer side of the lower end of the cartridge body, and a snap-fit ​​hole on the electrode metal sleeve that cooperates with the connecting buckle, so that the electrode metal sleeve is snapped together with the cartridge body.
