Multi-stage telescopic igniter

Abstract

The invention relates to a multistage telescoping igniter which can telescope between the inner unit and frame. The invention comprises a frame and an inner unit, while a middle sheath connected with the button exposed outside the frame is arranged between the frame and the inner unit. The middle sheath has telescope match with the inner unit and the frame, while the match between the middle sheath and the inner unit is formed by the long tooth bar fixed at the lower part of the frame of inner unit and the rolling gear fixed at the middle sheath. And the match between the middle sheath and the frame is formed by the long tooth bar fixed on the upper part the inner wall of frame and the rolling gear fixed on the middle sheath. The invention has long telescope strike and easy operation.

Description

technical field [0001] The invention relates to an igniter, in particular to a novel multi-stage retractable igniter whose internal unit and shell can be retracted. Background technique [0002] At present, the igniters that appear and report on the market and in magazines are roughly divided into two types, one is a lighter for lighting cigarettes, and the other is an ignition gun suitable for special occasions. It has its own strengths, so it is difficult for one product to have the functions of two products; as a lighter, because its structural characteristics are short, small and light, it is very suitable for carrying around, and people often take it with them for smoking; , because it is characterized by a relatively long length, it is very suitable for lighting candles, gas stoves and other places. Of course, there also exists a kind of igniter with telescopic function (also can be referred to as igniter here) as the patent No. is a kind of telescopic igniter of 0327...

AI Technical Summary

Problems solved by technology

The above-mentioned patents have the following deficiencies: 1. The ignition electronics, air box and gas inlet and outlet components of this ignition gun are installed on the gun shell, and the fire outlet component is installed on the gun head, so when the gun head stretches up and down, the inside of the gun head The air outlet pipe connected to the air box and the wire connected to the piezoelectric electronics move with the gun head, so it is easy to cause the rupture of the air outlet pipe and the disconnection of the wire, which eventually leads to the scrapping of the ignition gun; 2. This structure The telescopic stroke of the ignition gun is very small, so it is difficult to meet the needs of consumers

[0003] In addition, the applicant has also applied for a patent on the retractable igniter before this. Although this patent has solved the problems of the above-mentioned existing patents to a certain extent, because its expansion and contraction is the expansion and contraction between the internal unit and the outer shell, so Its telescopic stroke is also subject to certain restrictions, and in some occasions it cannot meet the needs of consumers.
