Water outlet device

A water outlet device, comprising:

• a body provided with a water passing chamber and a water outlet, wherein the water passing chamber is provided with a water passing port connected to the water outlet, an inner wall of the water passing chamber is provided with a plurality of inner gear teeth, and each of the inner gear teeth is disposed around a first axle line extending along a first direction;
• an impeller disposed in the water passing chamber, rotatably connected to the body around the first axle line and adapted to rotate when water enters the water passing chamber, and provided with an eccentric shaft extending along the first direction and along a second axle line parallel to the first axle line;
• a speed reducing member disposed in the water passing chamber, rotatably connected to the eccentric shaft, and provided with a plurality of outer gear teeth adapted to be engaged with the inner gear teeth, wherein each of the outer gear teeth is disposed around the second axle line, a number of teeth of the outer gear teeth is less than a number of teeth of the inner gear teeth, and the speed reducing member is further provided with a driving shaft extending along the first direction;
• and
• a switching member disposed in the water passing chamber and sliding and cooperating with the body along a second direction perpendicular to the first axle line, and provided with a blocking portion, wherein the blocking portion is attached to a surface where the water passing port is located, the switching member is provided with a driving groove extending in a direction perpendicular to the second direction and the first axle line, and the driving shaft is adapted to extend into the driving groove and abut against a groove wall of the driving groove, so that the blocking portion slides repeatedly relative to the body along the second direction to change a water passing area of the water passing port.
