Problems solved by technology

[0006] Some inventions try to solve the safety problem not by preventing the trigger from being depressed, but by preventing the gas release mechanism from working
Of course, in a multi-purpose igniter including such a mechanism, no flame can be created in the locked position since the gas cannot be released until the locking mechanism is released.
However, such multipurpose igniters cannot prevent sparks
Therefore, these types of igniters only partially solve the safety problem, because children still have the potential to start a fire when they are played with the igniter in close proximity to a gas source, or near carpet, paper, or other combustible objects

Embodiment Construction

[0040] Before detailing the improvements constituting the safety feature of the present invention, the piezoelectric multi-purpose igniter (1) (FIG. 1) will be generally described.

[0041] The parts of multi-purpose igniter (1) generally include: a igniter housing (10); a support ring (110) is contained in the ignition rod on the front end of the igniter housing, and the support ring is slipped on the igniter housing On the overlapping part with the ignition rod (120); a fuel tank (30) (Fig. 3); a piezoelectric device (40) and a trigger (100).

[0042] The igniter housing (10) consists of two shell parts separated along the longitudinal axis of the igniter (1). The igniter housing (10) has a rear end (10a) (FIG. 1) and a front end (10b) with a support ring (110) that engages the ignition rod (120). The firing rod, which is generally cylindrical, includes a free end constituting the top end of the igniter (1) and an engaging end connected to the front end of the igniter housi...

Abstract

A safety mechanism of a utility lighter. In a first preferred embodiment, the safety mechanism includes a safety button and a cam mechanism having a fuel release lever, a cam lever, and a return spring. When the cam mechanism is in the locked position, the cam lever engages the stopper tab of the trigger to impede depression of the trigger, and the fuel release lever closes the fuel release valve. The cam mechanism is actuated by depressing the safety button. As the safety button is depressed, the cam lever is disengaged out of alignment with the stopper tab to permit depression of the trigger, the hub rotates, and the fuel release lever is actuated to open the fuel-release valve. As the safety button is released, the return spring urges the cam mechanism into the locked position.

Description

[0001] This application is a divisional application, the application number of its original application is 01109184.3, the application date is March 19, 2001, and the title of the invention is "multi-purpose igniter for child protection with sliding safety button". technical field [0002] The invention relates to a multi-purpose igniter comprising a safety part, and the safety part includes a safety button, wherein, when the safety button slides forward, the gas release valve is opened and the trigger is released. Background technique [0003] Multi-purpose igniters are very useful and are widely used today. Multi-use lighters of the type described herein generally include a handle and an elongated firing rod. The shape and operation of the multi-purpose igniter has several advantages over conventional ignition methods. Most importantly, since the ignition rod is elongated, the operator can stand at a safe distance from the object to be ignited to ignite, thereby preventin...
