High-voltage retractable electric spark igniter

Abstract

The invention discloses a high-voltage retractable electric spark igniter. The high-voltage retractable electric spark igniter comprises a rack, a fuel tank is arranged on the rack, a fuel opening isformed in the top of the fuel tank, a first fixing hole and a second fixing hole are formed in the rack, an igniter frame, a clamping sleeve and an ignition rod are arranged in the first fixing hole,and a through hole is formed in the igniter frame; an open hole is formed in the end, facing the fuel opening, of the igniter frame, the ignition rod is located in the through hole and comprises a rodbody and a piston body, and one end of the rod body is fixed to the piston body; and an electrode frame is arranged in the second fixing hole, the electrode frame comprises a spark plug and a flexible electrode, and the other end of the flexible electrode is fixed to the other end, extending out of an opening, of the rod body. The high-voltage retractable electric spark igniter has the beneficialeffects that the end of the flexible electrode is driven to move front and back through front-back movement of the ignition rod and reaches an ignition point in the moving process, and after flames are ignited, the flexible electrode can be driven by the ignition rod to return without interfering combustion of the flames.

Description

technical field [0001] The invention relates to the technical field of igniters, in particular to a retractable electric spark igniter under high pressure. Background technique [0002] The burner is a general term for devices that make fuel and air spray out and combust in a certain way. Burners are divided into industrial burners, burners, civil burners, and special burners according to types and application fields. [0003] The igniter is a very critical step in the burner. The traditional ignition method is a fixed igniter, which uses a low-pressure operation igniter. Although this igniter can also ignite the fuel in the fuel port, but due to its ignition power setting Next to the fuel port, there will be interference when the flame burns, and the flame stability is poor, and the traditional low-pressure igniter cannot be used in a high-pressure environment, and the effect is not ideal.
