Abstract

The invention discloses a flame cutting knife. The flame cutting knife comprises a body (1), wherein the body (1) is provided with an acetylene pipe (4). The flame cutting knife also comprises an inductor (3), wherein the inductor (3) is arranged on an inner wall of the acetylene pipe (4). An ignition device (2) is arranged at an outlet of the body (1) and is electrically connected with the inductor (3). According to the flame cutting knife, the inductor (3) is arranged in the acetylene pipe (4), and the ignition device (2) electrically connected with the inductor (3) is arranged at the outletof the body (1), so that the ignition device (2) can be triggered to work immediately once gas flow in the acetylene pipe (4) is detected, and automatic ignition is realized.

Description

technical field [0001] The invention relates to a flame cutter, which belongs to the field of cutting tool supplies. Background technique [0002] Flame cutting machine is a kind of cutting equipment that uses gas with oxygen or gasoline with oxygen to cut metal materials. Mainly used in heavy industry. The hand-held flame cutting machine is also called a flame cutter, which mainly includes a main body, which is provided with an acetylene tube and an oxygen tube, and the gas is turned on and off through the valve of the air inlet, and the outlet is connected. When the existing flame cutter is ignited, it often needs to be operated by manual ignition. One hand holds the body, and the other holds the fire source, which often causes inconvenience in actual use. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a flame cutter capable of automatic ignition. [0004] The ...
