The invention provides a valve opening and closing control mechanism that can effectively protect the valve and motor, including: a housing (6), a motor (1), a reduction gear set (2) and a cam (3). The motor (1) The reduction gear set (2) is arranged in the housing (6); the output shaft (241) of the valve opening and closing control mechanism passes through the housing (6) and is driven by the reduction gear set. (2) Drive; the cam (3) is installed on the output shaft (241), wherein the reduction gear set (2) includes a driving gear (21), a second-stage reduction gear (22) and a third-stage reduction gear (22). Reduction gear (23), the drive gear (21) is driven by the output shaft of the motor (1), the drive gear (21) meshes with the second-stage reduction gear (22), and the second-stage reduction gear (22) The reduction gear (22) meshes with the third-stage reduction gear (23).
Description
technical field [0001] The invention relates to a valve opening and closing control mechanism. Background technique [0002] For a valve device controlled by a motor, the opening and closing control of the valve is usually realized by using a valve opening and closing control mechanism in cooperation with the motor. For example, the opening and closing of the drain valve used in the washing machine and other drainage systems is completed by the cooperation of the drain motor and the corresponding valve opening and closing device. When the washing machine needs to drain water, start the motor and open the drain valve; keep the drain valve open for a period of time to discharge the required amount of water; [0003] The existing valve opening and closing control mechanism has the following defects: the structure of the valve control device is complex, the operation is unstable, and the cost is high; the reliability of the control of the valve opening and closing action is low...
