Explosion prevention type ligher

Abstract

The invention relates to an explosion-proof lighter which comprises a shell, a piezoelectric device in the shell, a combustion chamber, a gas valve component and a windshield, wherein the upper end of the shell is provided with a press hand abutted against a piezoelectric cap in the piezoelectric device; the invention is characterized in that the shell is provided with a through hole on a dividing wall for dividing the combustion chamber and the space for holding the piezoelectric device, and the through hole is sealed by a sealing plug of elastic materials; compared with the prior art, when the explosion-proof lighter provided in the invention meets the sharply-increased pressure intensity in the high-temperature combustion chamber, the elastic sealing plug is propped open by the strong pressure, and the liquid gas partially flows into the space for holding the piezoelectric device in order to reduce the pressure intensity in the combustion chamber, which avoids the explosion of the lighter; as the space for holding the piezoelectric device is closed, the partial liquid gas flowing into the space for holding the piezoelectric device isn't sprayed outside the lighter body all at once, which avoids accidents and simultaneously effectively reduces the possibility of a fire; therefore, the explosion-proof structure is relatively safe and reliable.

Description

technical field [0001] The invention relates to a lighter, in particular to an explosion-proof lighter. Background technique [0002] At present, existing gas lighters generally include a housing, a piezoelectric device located in the housing, a gas chamber and its gas valve assembly, and a windshield. When in use, you only need to press the button, and the piezoelectric cap of the piezoelectric device will be compressed. When the compression stroke reaches the ignition stroke, the piezoelectric device will release high-voltage electric energy due to the impact of the hammer inside the piezoelectric crystal. And through the conductive circuit, an electric spark is sent at the gas outlet of the gas valve assembly, and the gas valve assembly releases gas at the same time under the action of pressing the hand at this time, and the gas meets the electric spark to realize ignition. [0003] The original gas lighters generally store the gas in the gas chamber. When the lighter is...

Problems solved by technology

Although the structure of the above-mentioned explosion-proof lighter can achieve the purpose of explosion-proof, because it separates the gas storage chamber from the casing, and at the same time increases the gap between the gas storage chamber and the casing, the entire lighter must be "sacrificed" under the condition of ensuring the volume of the gas storage chamber Explosion-proof purpose is achieved at the expense of the volume of the shell, which will increase the overall volume of the lighter, and the structure is bulky, which is not conducive to carrying; at the same time, rubber material is used as the air storage chamber. Because the rubber material is easy to age, the service life is not long, and the aging of the rubber air storage chamber Using a lighter under normal circumstances may cause dangerous situations such as air leakage
