Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, specifically to a child-locking oil cup structure for electronic cigarettes. 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, e-cigarette structures that separate the e-liquid tank from the atomizer core have emerged. These structures allow for quick refilling of e-cigarettes by replacing the e-liquid tank. Existing e-liquid tanks have an e-liquid outlet, which is sealed with a cap before use. However, the lack of a child lock makes it easy for children to open the cap and accidentally ingest the e-liquid, posing a safety hazard. This fails to meet user experience requirements and is detrimental to product competitiveness. Utility Model Content
