Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and particularly relates to a portable refillable electronic cigarette. Background Art

[0002] An electronic cigarette is an electronic product that imitates cigarettes and has the same appearance, smoke, taste and feeling as cigarettes. It is a product powered by a rechargeable lithium polymer battery to drive an atomizer. By heating the e-liquid in the oil tank, nicotine and the like are turned into vapor and then inhaled by users. An electronic cigarette mainly consists of four parts: e-liquid (containing nicotine, flavor, solvent propylene glycol, etc.), a heating system, a power source and a filter tip. It generates an aerosol with a specific smell through heating and atomization for smokers to use. Generally speaking, an electronic cigarette refers to an electronic nicotine delivery system, including various forms such as electronic cigarettes, hookahs, and e-hookah pens. Narrowly speaking, an electronic cigarette specifically refers to a portable electronic cigarette with a shape similar to that of a cigarette. Although there are various models or brands of electronic cigarettes, generally an electronic cigarette mainly consists of a cigarette tube containing nicotine solution, an evaporation device and a battery. The atomizer is powered by a battery rod and can turn the liquid nicotine in the cartridge into mist, so that the user has a feeling similar to smoking when inhaling and realizes "smoking clouds and puffing mists". It can even add various flavoring spices such as chocolate and mint into the cigarette tube according to personal preferences.

[0003] Most of the existing e-cigarettes use disposable cartridges. After the e-liquid inside is used up, it needs to be replaced. This method is costly, and the cartridges are not easily recyclable, resulting in waste. To address the above problems, a patent with the patent number 202122295766.5 was invented, which discloses an e-cigarette convenient for adding e-liquid, including a cigarette rod, a cartridge, a plug-in slot, an oil injection hole, an oil injection pipe, a connecting sleeve, an oil storage tank, an inhalation hole, a support piece, a leakage hole, a spring, and a rubber block. A plug-in slot is provided at the top of the cigarette rod. A cartridge is provided at the top of the pressing rod, and the bottom of the cartridge is slidably inserted into the plug-in slot. An oil storage tank is provided inside the cartridge. An oil injection hole is provided at the top of the cartridge, and the oil injection hole communicates with the oil storage tank. An inhalation hole is provided inside the cartridge. A support piece is fixedly connected to one side inside the oil storage tank. A leakage hole is provided at the top of the support piece. A rubber block is slidably inserted at the bottom of the oil injection hole. The e-cigarette convenient for adding e-liquid provided by the present utility model can be refilled when the e-liquid is used up, saving the cost of replacing the cartridge, facilitating the reuse of the cartridge, reducing waste, and being simple and labor-saving when adding e-liquid. However, the e-cigarette still has the following problems: 1. The sealing effect of the oil injection structure is poor. Since the cartridge needs to be heated at a high temperature to atomize, the rubber block may shift or age after long-term use or frequent sliding, resulting in oil leakage problems, affecting the use of the e-cigarette and having a short service life; 2. The existing e-cigarettes use a temperature sensor to monitor the temperature inside, but the temperature prompt of this method is poorly intuitive, and it needs to be powered on for monitoring, with low practicability and prompt efficiency, affecting the use safety.
