Controllable silicon trigger circuit of continuous mouse trapping boxes

Abstract

A SCR trigger circuit of continuous mousetrap belongs to the electric control technology field. At present, the deficiencies are widely existed in the mousetrap control circuits of the market, such as the lack of self recovery after the false triggering, the lack of self-stopping of the alarm sound, the low sensitivity, the large standby power and so on. The SCR trigger circuit is in the utilization of a SCR control motor to work. When a mouse touches the mechanical sensor, the triggering voltage is in conduction through the triggering of the occlusive mechanical sensor to the SCR, and the pulling tray is driven through the rotation of the motor to open. When the pulling tray is completely open, the closing contact of the normally closed switch in series connection in the power supply circuit is daffed, so that the SCR can be in cut-off due to the loss of power. The pulling tray is driven through a compression spring to be in self-closing, thus the SCR trigger circuit gets back to the standby status for the next mouse capture. The utility model has the advantages of self recovery after the false triggering, alarm sound self-stopping, high sensitivity, very low standby power, which can work with AC or DC power supply.

Description

technical field [0001] The invention relates to a thyristor trigger circuit of a continuous mouse trap, which belongs to the technical field of electronic automatic control. Background technique [0002] At present, the mousetrap control circuit on the market generally has various deficiencies: it cannot automatically recover after being triggered by mistake; the alarm sound cannot stop by itself; the sensitivity is not high; the delay circuit of the mousetrap has a large error; Poor safety performance; large current during standby; working voltage cannot be freely switched to AC or DC. Contents of the invention [0003] The technical problem to be solved by the invention is to introduce a thyristor trigger circuit for a continuous mouse trap. This circuit does not have the common shortcomings of the current mousetrap control circuit. It will automatically resume the standby state after being triggered by mistake. The trigger sensitivity is high, and the standby power con...
