Description

Piezoelectric ceramic ignition device for lighters

Technical Field

The utility model relates to a piezoelectric ceramic ignition device for a lighter.

Background Art

At present, all lighters use ceramic piezoelectric ignition devices, which use flammable gases such as butane and natural gas as fuel. By pressing the ignition button by hand, the piezoelectric material in the ignition device generates sparks and then ignites the released flammable gas to produce a flame. Its structure and working principle are as follows: under the pressure of the ignition button, the piezoelectric push rod drives the hammer downward to hit the striking body on the piezoelectric ceramic, and the piezoelectric ceramic generates high voltage electricity. One end of the piezoelectric ceramic is connected to a wire, and the wire is set to the air outlet of the lighter. When the piezoelectric push rod drives the hammer downward to hit the piezoelectric ceramic, the air outlet valve will be opened to release the flammable gas. The wire discharges instantly at the air outlet, generating an electric spark to ignite the gas.

The existing piezoelectric ceramic ignition device for lighters also has the disadvantage that after the wire is connected to the piezoelectric ceramic and passes through the shell, the wire is in a free state, so the wire is relatively messy and bent and not neat. At present, the piezoelectric ceramic ignition device is basically assembled into the lighter by automatic assembly. The randomly bent wire brings great trouble to the automatic assembly process of the piezoelectric ceramic ignition device into the lighter, and the wire needs to be manually straightened.

Summary of the invention

In order to overcome the above-mentioned shortcomings of the existing piezoelectric ceramic ignition device for lighters, the utility model provides a piezoelectric ceramic ignition device for lighters with a positioning mechanism of a wire.

The utility model solves the technical problem by providing a piezoelectric ceramic ignition device for a lighter, comprising a shell, a piezoelectric push rod capable of moving up and down is provided at the upper end of the shell, a hammer and a piezoelectric ceramic located below the hammer are provided in the shell, the hammer is connected to the lower end of the piezoelectric push rod, a striking body corresponding to the hammer is provided at the upper end of the piezoelectric ceramic, the piezoelectric ceramic is connected to a wire, and the wire passes through the shell;

A positioning mechanism for positioning the wire is provided on the wire exiting surface of the shell, and the wire is positioned on the positioning mechanism.

Furthermore, the positioning mechanism includes: a buckle is provided on the wire outlet surface of the shell, and the wire is snapped into the buckle.

Furthermore, the buckle is integrally formed with the shell.

Furthermore, a guiding slope is provided at the opening of the buckle.

Furthermore, the positioning mechanism also includes: a positioning groove is provided on the wire outlet surface of the shell, the positioning groove is located at the outlet of the wire, the tail of the wire is located in the positioning groove, and filler is also provided in the positioning groove so that the tail of the wire is buried in the filler.

Furthermore, the positioning groove is integrally formed with the shell.

The utility model has the beneficial effect that the wire is positioned on the positioning mechanism so that the wire will not be bent, and the wire is straightened before the piezoelectric ceramic ignition device is assembled into the lighter, which is beneficial to the automatic assembly of the piezoelectric ceramic ignition device.
