The electrical valve control device contains a cover member and a base member joined together. A motor is joined to the cover member's outer surface, and its axle configured with an axial gear threads through the cover member. A transmission gear having a track engages the axial gear. A valve assembly has a nozzle, a plug tube, and a channel connected to the plug tube at one end. The other end of the channel is an open end and is in the same space as the nozzle. A cover piece is positioned in front of the open end of the channel, and is joined to a first end of a shaft threading through a helical spring. A second end of the shaft is connected to an end of a lever. A pin is extended from the second end of the lever and is embedded in the transmission gear's track.
