Control circuit and control method of self-suction electromagnetic valve

Abstract

The invention discloses a control circuit and a control method of a self-suction electromagnetic valve. The control circuit comprises: a self-suction electromagnetic valve; a battery module, which is connected with the self-suction electromagnetic valve; a boosting energy storage module, which is connected with the self-absorption electromagnetic valve and is used for charging and storing energy and discharging the self-absorption electromagnetic valve; a battery sampling module, which is connected with the battery module and is used for collecting real-time voltage Vbat output by the battery module; and a control module, which is electrically connected with the self-absorption electromagnetic valve, the battery module, the battery sampling module and the boosting energy storage module. According to the control circuit, power is supplied to the self-suction electric valve magnet through the two power sources, the charging duration needed by the boosting energy storage module is automatically calculated and adjusted, the constant suction force of the self-suction electric valve magnet is achieved, and the valve opening capacity is improved.

Description

technical field [0001] The invention relates to the technical field of cooker, in particular to a control circuit and a control method of a self-priming electromagnetic valve. Background technique [0002] At present, self-priming solenoid valves for cookers rely entirely on electric power to drive the valve body to pull in and do not need to rely on manual external force to complete the pull-in, and the valve control is relatively simple. However, in practical applications, due to the influence of the environment, the valve sticks, or the influence of the over-tolerance of the valve body's suction stroke causes the pull-in voltage to increase. When the power supply voltage remains unchanged, the pull-in ability becomes poor, or even does not pull in. As a result, the stove does not ignite, which affects the user experience. [0003] When the battery drives the self-priming solenoid valve, due to the internal resistance of the battery itself, the output voltage decreases wi...

However, in practical applications, due to the influence of the environment, the valve sticks, or the influence of the over-tolerance of the valve body's suction stroke causes the pull-in voltage to increase. When the power supply voltage remains unchanged, the pull-in ability becomes poor, or even does not pull in. As a result, the cooker does not ignite and affects the user experience

[0003] When the battery drives the self-priming solenoid valve, due to the internal resistance of the battery itself, the output voltage decreases with the increase of the internal resistance, and the suction force is weaker, which affects the ignition performance of the stove.
