The oblique triggering driving circuit comprises an oblique detecting circuit, a logic control circuit, a timedelay recovery circuit and a driving stage circuit, wherein the oblique detecting circuit is used for detecting an inclination angle of an electronic product and generating a first detecting signal or a second detecting signal. The logic control circuit is used for generating a charging signal according to the first detecting signal. The logic control circuit is used for generating a dischargingsignal according to the second detecting signal. The driving stage circuit is connected with a time delay recovery circuit and a load power supply loop of the electronic product. The time delay recovery circuit is used for generating a conduction signal according to the charging signal. The time delay recovery circuit is used for generating an off signal according to the discharging signal. The driving stage circuit is used for controlling the load power supply loop to be electrified according to the conduction signal. The driving stage circuit is further used for controlling the load power supply loop to be de-electrified according to the off signal, wherein the time delay recovery circuit generates the conduction signal and / or the off signal in a delayed manner.

The invention discloses an electronic control type thermostat, and relates to the thermostat. The thermostat comprises a sealed shell, a micro direct current motor, a slide rod mechanism and a computer control system. The micro direct current motor is fixedly arranged in the sealed shell, and the input end is connected with a motor control line and the output end is provided with an output gear. The slide rod mechanism comprises a slide rod, a combined gear and a sliding resistor. The slide rod is provided with a sliding rod tooth, and an elliptical valve body is formed at the end of the slide rod. The combined gear comprises a rack wheel and a pinion. The rack wheel is engaged with an output gear, and the pinion is engaged with the slide rod. The sliding resistor is installed below the slide rod and is connected with the slide rod. The output end of the sliding resistor is connected with a detection line and a grounding line. The detection line, the grounding line and the motor control line are respectively led out the sealed shell and are respectively connected with an input / output end of the computer control system. According to the electronic control type thermostat provided by the invention, the valve can be quickly opened and closed, overhigh and overlow temperatures of water in an engine can be avoided, and abrasion and oil consumption amount can be reduced, so that the electronic control type thermostat is wide in application range.
