## Abstract

The present discloses a toy duck comprising a main body shaped as a duck; a nozzle disposed on the main body for spraying water in case the main body is pressed externally; a hole at the bottom of the main body for receiving a piston assembly; and a piston assembly disposed in the hole for sealing the main body so as to prevent water from leaking from the main body, and allowing complete drainage of water in the toy duck when the toy duck is disposed on a horizontal panel to keep the duck toy clean and hygienic. The internal cavity of the main body will not contain water any more due to the piston assembly, and can be kept clean and hygienic, which is not suitable for generation and growth of bacteria therein. The new toy duck will not cause harm to health of the children.

## Claims

### Claim 1

A toy duck comprising:
a main body having a cavity for containing water, which is made of plastic and shaped as a duck;
a nozzle disposed on the main body for spraying water in case the main body is pressed externally;
a hole at the bottom of the main body for receiving a piston assembly; and
a piston assembly disposed in the hole for sealing the main body so as to prevent water from leaking from the main body, and allowing complete drainage of water from the cavity when the toy duck is disposed on a horizontal panel to keep the duck toy clean and hygienic.

### Claim 2 (depends on 1)

The toy duck according to claim 1, wherein the piston assembly comprises:
a piston composed of a circular top and a cylindrical end;
a base which is provided a central hole and a plurality of receiving grooves; and
a circular dome comprises a top and a side wall, which is provided a hole at the top and a plurality of gaps at the side wall;
and wherein the circular dome is combined with the base, and the piston is movably disposed in a space created by the circular dome and the base.

### Claim 3 (depends on 2)

The toy duck according to claim 2, wherein a top end of the piston is inserted into a bottom of the main body of the toy duck by the hole of the base.

### Claim 4 (depends on 2)

The toy duck according to claim 2, wherein the piston is made of plastic or rubber.

### Claim 5 (depends on 2)

The toy duck according to claim 2, wherein the central hole is a circular hole.

### Claim 6 (depends on 2)

The toy duck according to claim 2, wherein the piston is movable along the side wall of the circular dome.

### Claim 7 (depends on 2)

The toy duck according to claim 2, wherein three gaps are arranged on the side wall of the circular dome.

### Claim 8 (depends on 2)

The toy duck according to claim 2, wherein the piston assembly is assembled on the main body of the toy duck, water is flowed into the cavity of the main body from the hole and gaps of the circular dome and the central hole of the base.

### Claim 9 (depends on 8)

The toy duck according to claim 8, wherein the toy duck full of water is pressed externally, the piston is pushed downwardly by water pressure so that the central hole of the base is blocked by the piston to prevent water from leaking from the main body, other than the nozzle.

### Claim 10 (depends on 8)

The toy duck according to claim 8, wherein the toy duck full of water is disposed on a horizontal panel, the piston is pushed upwardly to open the hole of the base and allow water flowing from the main body by the increasing pressure of the horizontal panel because the piston is protruded from the bottom of the toy duck.

### Claim 11 (depends on 1)

The toy duck according to claim 1, wherein the hole is a circular hole.

### Claim 12 (depends on 1)

The toy duck according to claim 1, wherein the base is provided with a plurality of foot supports at the bottom thereof for supporting the piston assembly on a horizontal panel so that water can be flown smoothly from the main body quickly when there is a need to drain off water.

### Claim 13 (depends on 12)

The toy duck according to claim 12, wherein the base is provided with three foot supports.
