AI Technical Summary

Technical Problem

Existing lighters suffer from a large number of parts and a reduced housing capacity, especially due to the sealing component being located at the bottom of the housing, which limits sealing and capacity.

Method used

The oil filling hole is located on the top of the housing, and the rotation of the ignition element is controlled by the drive wheel to achieve the sealing and opening of the oil filling hole. The sealing and ignition functions are integrated on the same side, reducing the number of parts.

Benefits of technology

It simplifies the fuel filling process, reduces the number of parts, solves the problem of reduced housing capacity, and improves sealing and ignition reliability.

Abstract

This utility model discloses a lighter, including a housing, an oil filling hole on the upper surface of the housing, and an ignition element for sealing the oil filling hole. A drive wheel is also provided on one side of the housing. Counterclockwise rotation of the drive wheel causes the ignition element to move downwards and block the oil filling hole. Clockwise rotation of the drive wheel causes the ignition element to move upwards, separating it from the oil filling hole. The ignition element includes a sealing component and a friction component rotatably mounted at one end of the sealing component. The lower end of the friction component passes through the sealing component and is linked to the drive wheel. A flint is also provided inside the sealing component, and the ignition element ignites by rubbing against the flint with the friction component. Based on this, while achieving normal ignition, the oil filling hole is located on the upper part of the housing, and the ignition element, following the rotation of the drive wheel, can block or release the oil filling hole, thus facilitating the user to add fuel into the housing.
