Idling flameout switch of general gasoline engine

Abstract

The invention relates to an idling flameout switch of general gasoline engine. A box body of a flameout switch seat is arranged on a base; a first elastic sheet in the box body is provided with an upper end surface and a lower end surface provided with clamping slots; the end surface is provided with a bending surface; a second elastic sheet is provided with an opening from the middle part to the end surface of one end to form a 'U' shape; the opening end of the second elastic sheet after being bent is embedded in the clamping slot and the other end is provided with a contact point; one end of a third elastic sheet after being bent extends the bending surface of the first elastic sheet and is fixedly connected with the first elastic sheet and the other end is fixed on the base of a throttle control combination; one end of a return spring is fixed at the bending end of the third elastic sheet and the other end is fixed in a hole beside the opening in the middle part of the second elastic sheet; a contact button penetrates the box body and is in contact with the first elastic sheet; the inside of the box body is provided with a fourth elastic sheet; and one end of the fourth elastic sheet is provided with a contact point which opposites to the second elastic sheet and the other end extends out of the box body and is connected with a ground circuit. The idling flameout switch has good safety and stability, is not easy to lose effect, and can better control the flameout of the engine.

Description

technical field [0001] The invention relates to a general gasoline engine, in particular to an idle stop switch of a general gasoline engine. Background technique [0002] At present, the existing domestic engine flameout method is carried out through the flameout switch, and there are few flameouts through the accelerator control combination. The flameout device of the existing structure achieves the purpose of flameout by directly contacting the shrapnel of the flameout switch by rotating the throttle handle left and right. When the handle is controlled, the shrapnel of the flameout line is easily deformed, and the stability is not easy to control. When the deformation exceeds the limit of the rotation angle of the handle, the flameout cannot be achieved. Purpose. [0003] The applicant applied for an idle stop switch for a general-purpose gasoline engine on November 26, 2008. The throttle control combination is fixed on the top of the starter, the handle is fixed on the ...

AI Technical Summary

Problems solved by technology

The contact end of the flameout switch is a V-shaped shrapnel. Long-term extrusion will easily deform the contact piece, and the gap between the contact piece and the throttle handle will become larger, causing the throttle handle to fail to contact with the contact piece, making the flameout switch invalid.
