Drain valve controller

Abstract

The present invention discloses a drain valve controller, which comprises a body, a driving wheel, a driven wheel, a bracket, a motor, a rack, a rotary damper, a reset member, and a reset spring. The motor is fixedly arranged on the body to output power for the driving wheel. The first rotating part of the rotary damper is coaxially fixedly arranged with the driving wheel, and the second rotating part is fixedly arranged with one end of the bracket. The driven wheel is rotatably arranged on the other end of the bracket and meshes with the driving wheel, and the rack is slidably arranged on the body.

[0005] The present invention has a simple structure and realizes: when the motor is working, the rack can move downward, thereby pushing the drain valve below, triggering the drain valve to drain water; when the motor is powered off and not working, the rack can automatically reset and will not continue to press the drain valve, thereby causing water waste.

[0006] Optionally, two racks are provided, respectively located on both sides of the driving wheel; when the motor rotates forward, the bracket swings to the left, and the driven wheel engages with the rack on the left; when the motor rotates reversely, the bracket swings to the right, and the driven wheel engages with the rack on the right.

[0007] By setting two racks, which are used to control the large and small drain buttons of the drain valve respectively, the functions of full drain and half drain can be easily achieved.

[0008] Optionally, a movable bin is provided on the bracket, the rack is slidably provided in the movable bin, a sliding bar is provided in the movable bin along the reverse direction of movement, and a sliding groove cooperating with the sliding bar is provided at a corresponding position of the rack.

[0009] The setting of the movable bin can effectively protect the running smoothness of the rack, and it is not easy for debris to fall in and cause jamming.

[0010] Optionally, a baffle is provided on the side of the rack facing away from the teeth, a fixing column is provided below the baffle, and the return spring is fixed on the fixing column, with the upper end against the baffle and the lower end against the bottom surface of the movable bin.
