Abstract:
A cleaning device for cleaning pet excrement comprising:a supporting member; a conical tray that is mounted on said supporting member so as to be adapted to receive pet excrement falling from a pet cage, and that is formed with a central opening; a hollow connecting member extending through said central opening in an axial direction relative to said central opening, said hollow connecting member being connected to said conical tray, confining an axial channel that extends in said axial direction, and being formed with a plurality of angularly spaced apart through-holes that are in fluid communication with said axial channel, said hollow connecting member being adapted to be connected to a water supply for supplying water into said axial channel; and a cleaning unit including a central sleeve that is rotatably sleeved on said hollow connecting member, that is disposed to surround said through-holes, and that is formed with a plurality of spaced apart passages which are in fluid communication with said through-holes, said cleaning unit further including a plurality of angularly spaced apart elongated tubular members, each of which is disposed above said conical tray, each of which extends upwardly and inclinedly from said central sleeve in a radial direction relative to said conical tray, each of which is formed with an ejection open end opposite to said central sleeve, and each of which confines an ejection channel that extends from said central sleeve to said ejection open end and that is in fluid communication with a respective one of said passages in said central sleeve, said ejection open end opening in an ejection direction transverse to said radial direction so as to permit rotation of said cleaning unit about said hollow connecting member by virtue of a counteracting force resulting from ejection of water from said ejection open ends of said tubular members when water is supplied into said tubular members via said axial channel, said through-holes, and said passages, thereby permitting cleaning of said conical tray.
