CN201575476U - Retractable gas ignition gun - Google Patents

Abstract

The utility model relates to an ignition gun, in particular to a gas ignition gun with a retractable ignition gun barrel. The ignition gun comprises a housing and the ignition gun barrel, wherein the ignition gun barrel is a retractable barrel; an impact block and a piezoelectric material block are arranged in the housing; and the vibration generated by the impact of the impact block and the piezoelectric material block is transmitted through a conductive wire and then forms eclectic sparks at an outlet of the ignition gun barrel, which ignites gas. The utility model has the advantages of simple structure, capability of retraction, safe use, portability, no need of batteries, and energy conservation.

Description

Scalable coal gas ignition rifle

Technical field

The utility model relates to a kind of igniter, is specifically related to the telescopic coal gas ignition rifle of a kind of igniting gun barrel.

Background technology

Existing many gas ranges do not have the igniter of installation and kitchen range one, also use the lighter igniting, and are very dangerous during use; Though existing burning torch has avoided using the danger of lighter, oversize because of the igniting gun barrel, take up room during placement, deposit inconvenience.

Summary of the invention

The purpose of this utility model is to provide a kind of igniting gun barrel telescopic coal gas ignition rifle, has both avoided using the dangerous of lighter, has also overcome the big shortcoming of existing burning torch volume.

Scalable coal gas ignition rifle described in the utility model, comprise housing and igniting gun barrel, the gun barrel of wherein lighting a fire is a telescoping tube, metal tube is nested forms by at least two joints, retractable during use draws back the igniting gun barrel, and the time spent is not again with its pinch in, reduce occupation space, conveniently deposit and carry; Comprise impact block, spring, block of piezoelectric material, thin wire and supporting construction thereof in the housing; Impact block is connected with shift knob on the shell, and spring is connected with shift knob and is positioned at the shift knob below; Block of piezoelectric material is connected with thin wire one end, is positioned at the impact block below.The Push switch button, impact block bump block of piezoelectric material one end, the interior molecules of block of piezoelectric material will judder, the thin wire that vibrational energy connects through the other end is delivered to igniting gun barrel exit, the air molecule judder that causes the exit forms electric Mars (arclight), and then ignited flammable gas.When stopping the Push switch button, shift knob is return-to-home position under the effect of spring.

In the said apparatus, the burning torch inside pipe wall is provided with pendant, and thin wire is from its middle passing, and a plurality of pendants can be sling thin wire, thin wire knotting when the gun barrel that prevents to light a fire is flexible.

In the said apparatus, also be provided with and be used for supporting the backing plate of block of piezoelectric material and the spring-support plate of support spring.

Igniting gun barrel described in the utility model can stretch, and has significantly reduced occupation space, and is safe in utilization, easy to carry, and without battery, energy savings.
