Description

Technical Field

[0001] This disclosure relates to the field of electronic cigarette technology, and more particularly to an electronic cigarette with a built-in oil reservoir and an oil inlet that can be opened by pressing up and down. Background Technology

[0002] Electronic cigarettes are electronic products that use an electrically heated element to atomize e-liquid into vapor aerosol particles at high temperatures. Currently, there are many types of electronic cigarettes on the market, including pod-based and all-in-one models. Pod-based e-cigarettes use disposable or refillable cartridges, while all-in-one models also include disposable or refillable all-in-one models. Existing refillable models use a cartridge or reservoir with a filling port to draw e-liquid from an external reservoir for filling. Since a refillable reservoir is not always readily available, this solution is not flexible or convenient. For example, patent publication number CN222486210U discloses a dual-refill electronic cigarette device where the bottom of the reservoir is exposed. To refill, the bottom of the reservoir is pressed, pushing it towards the opening, thus connecting the opening to the main reservoir and allowing e-liquid from the reservoir to be added to the main reservoir. The bottom of the oil storage bottle in this design is exposed, and the entire bottle is moved by applying pressure to the bottom. Therefore, the bottle body needs to be made of a rigid material; if it is made of borosilicate glass, it may break upon impact when dropped. To address this, this technical solution optimizes and improves the design by embedding the oil storage bottle inside the main unit housing. The oil inlet is opened by pressing down from the top. This design is simpler, and the oil storage bottle can be made of either soft or hard food-grade materials. Utility Model Content

[0003] To achieve the above objectives, this disclosure proposes an electronic cigarette with a built-in oil reservoir and an oil inlet that can be opened by pressing up and down. The oil inlet is opened by pressing up and down the top of the oil reservoir, which hides the oil reservoir inside the main unit housing. This makes the appearance simpler and more beautiful, and also helps to protect the oil reservoir from breakage in the event of a drop.
