Tightly covered lighter

Abstract

To provide a tightly covered lighter protected from entering of sand, dust or the like into an internal combustion mechanism or the like in a lighter body, and can be used even in river, sea, rain, or highland, a windshield formed on a top of the lighter body, an ignition operator formed adjacently to the windshield, and a dome-shaped cap covering tops of the ignition operator and the windshield in an openable and closable manner are provided. A cover covers a top and / or a bottom of the lighter body in a watertight or airtight manner, and a clip is protrusively arranged on the cover or the lighter body.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an internal-combustion gas lighter having wind-proof, in which ignition and combustion of mixed gas are performed in a lighter body, and more particularly relates to a tightly covered lighter further having waterproof, weatherproof and pressure-proof.[0003]2. Related Art[0004]Hitherto, as a piezoelectric ignition gas lighter (so-called piezoelectric lighter) in which a combustion cylinder and the like are incorporated in a lighter body so that ignition and combustion of gas mixed with air are performed in the lighter body, various types of wind-proof gas lighters, so-called internal-combustion gas lighters have been devised.[0005]For example, such an internal-combustion gas lighter is configured to have an intake port for drawing air by negative pressure caused by ejecting fuel gas from a gas tank with increased flow velocity; a mixing tube accelerating mixing of the fuel gas with air; a...

Benefits of technology

[0008]The invention was made in the light of such previous difficulty and request, and an object of the invention is to provide a tightly covered lighter which is protected from entering of sand, dust or the like, and has excellent water-proof, weather-proof and pressure-proof despite the internal-combustion gas lighter having excellent wind-proof.

[0012]An embodiment of the invention is configured as above, and includes the cover covering the top and / or the bottom of the lighter body in the watertight or airtight manner, and the clip protrusively arranged on the cover or the lighter body, thereby it has excellent water-proof, weather-proof and pressure-proof, consequently a gas lighter which can be easily attached to a pocket of cloths, bag, or belt without concern for river, sea, rain, or highland (altitude), that is, an optimum gas lighter for the outdoors can be provided.

[0013]Moreover, the semicylindrical windshield halved in the longitudinal direction, and the semicylindrical ignition operator halved in the same direction are opposed and cylindrically aligned with each other, resulting in a compact and novel tightly covered lighter that can be ignited in a manner of sliding the semicylindrical ignition operator.

[0015]Moreover, the windshield is formed in the semicylindrical shape to compactly cover the internal combustion mechanism, and the ignition operator has the finger putting portion formed one step lower than the top surface of the windshield and the guard portion facing the windshield side, which are integrally connected to each other, to cover the piezoelectric mechanism, thereby even in the condition that the ignition operator is pressed down, a side face of the windshield (a side opposed to the ignition operator) is not opened unlike the usual, and the guard portion is moved along a face of the windshield to overlap with the side face, resulting in an advantage that entering of sand, dust or the like into the internal combustion mechanism or the piezoelectric mechanism can be prevented, consequently the gas lighter can be used even in river, sea or highland without worrying.

[0016]In this way, an embodiment of the invention can provide a tightly covered lighter in a high-grade specification, which is protected from entering of sand, dust or the like, and excellent in waterproof, weather-proof and pressure-proof despite the internal-combustion gas lighter, in addition, since the tightly covered lighter has a simple configuration, it is suitable for mass production and can be inexpensively provided to users, consequently carrying out of an embodiment of the invention has significantly large beneficial value.

Problems solved by technology

However, in the internal-combustion gas lighter disclosed in the JP-A63-91431, since a mixed gas created by a jet flow is combusted and ignited as burner, while there is an advantage that it can be used without any difficulty even in a strong wind, there is a difficulty that sand, dust or the like enters into an internal combustion mechanism or a piezoelectric mechanism in the lighter body since a burner port of a windshield is opened comparatively large.
