Patent ID: 7677202

Claim:
A pet cleaning apparatus comprising: a cleaning tub; a saturated solution generator connected to the cleaning tub and configured to generate a saturated solution by saturating a pressurized fluid with air; and an air-bubble generating nozzle connected to the cleaning tub and the saturated solution generator and configured to generate a fine air-bubble in the saturated solution, wherein the air-bubble generating nozzle comprises: a nozzle main body attached to an outer side of the cleaning tub and configured to generate the fine air-bubble in the saturated solution; and a fixed body attached to an inner side of the cleaning tub and the nozzle main body and configured to discharge into the cleaning tub the saturated solution in which the fine air-bubble is contained, wherein the nozzle main body comprises: a pipe configured to generate the fine air-bubble in the saturated solution; and a cylindrical portion attached to the fixed body and having a convection chamber which opens to the pipe and is configured to further generate a fine air-bubble in the saturated solution, and wherein the pipe includes a mesh member and an orifice member, which is independent of the mesh member and has a plurality of small holes, in a flow channel thereof through which the saturated solution passes, and the saturated solution is rapidly depressurized to generate the fine air-bubble therein after having passed through the small holes, and the generated fine air-bubble is atomized with the mesh member.
