Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and particularly relates to an electronic cigarette oil syringe. Background Art

[0002] An electronic cigarette, also known as an e-cigarette, is mainly used for quitting smoking and replacing cigarettes.

[0003] Currently, electronic cigarettes generally use e-liquid as the atomized substance to generate smoke by heating. To improve the service life of electronic cigarettes, manufacturers have added a refueling hole and a refueling plug to the e-liquid container (such as a cartridge) of the electronic cigarette. When refueling is needed, the refueling plug is pulled out of the refueling hole to refuel, and after refueling, the refueling hole is blocked by the refueling plug.

[0004] However, when injecting e-liquid into a matching electronic cigarette cartridge, a conventional disposable syringe is generally used for injection, that is, the e-liquid inside the disposable syringe is injected into the matching electronic cigarette cartridge. After each use of the disposable syringe, the disposable syringe will be discarded, and it cannot be reused, resulting in waste and environmental pollution, and failing to achieve the effect of environmental protection and energy conservation.
