Lighter

The present invention relates to a kind of lighter that has an igniter and to be used to seal the cap at wick top, described igniter comprises a flint and a file wheel, more particularly, the present invention relates to a kind of structure that is used to open and close cap.

As everyone knows, existing lighter is to burn liquefied fuel gas or liquid fuel, alcohol for example, and use the cap that is hinged on the lighter to open and close lighter.

As a kind of device that opens and closes cap, driving of well-known cap and a file wheel spool is driven coaxially, Japanese patent gazette No.53 (1978)-83872 by the agency of a kind of like this device.

Yet the shortcoming of this lighter is, because cap can not be opened by wide-angle ground, the top of cap also hinders closing of cap easily by flame heat, because cap is too near flame, the cap interference lights a cigarette.

In addition, comprise the cap on whole top of the lighter of file wheel for opening and closing, open and close the cap ratio and be easier to, and for only closing the cap that comprises a burner top part on the lighter, open just difficulty of cap.

In addition, if the opening action of cap is not interlocked with the action of lighting, then lighter is lighted in two steps, and this is pretty troublesome.

In addition, in the lighter of a use liquid fuel, during storage or analogue, when cap was opened, fuel can be evaporated or waste, thereby, in the time of in off position, preferably cap is pinned.

In view of above-mentioned viewpoint, main purpose of the present invention provides a kind of lighter, and its cap can be opened to wide-angle, and simultaneously not by flame heat, not directly under the situation of contact cap, cap is opened.Down, cap is locked in off position.

According to the present invention, a kind of lighter is provided, it comprises that the holder that is used for storage of fuels, the burner that is used for combustion fuel, one comprise the file wheel with a side wheel and the igniter of flint, flint is taken turns friction to produce spark with file under the file wheel, and one is used to support the support column of file wheel rotating shaft and the cap at an opening and closing burner top.Improvement wherein comprises:

Cap is supported in the bolster that is used to rotate away from an end of file wheel, be pushed open position by a spring towards it, at its end near the file wheel, have a limiter part, described limiter partly is adapted to be meshed with the rotating shaft of filing wheel.
