Abstract

A chemical feeding device according to the present invention is for attaching to a water tank of a toilet having a tank main body that has an opening in an upper portion and a lid body that covers the opening of the tank main body, the chemical feeding device including a chemical container storing a chemical solution, a flexible tube through which the chemical solution in the chemical container is fed to the water tank, and an attachment member that supports the tube and is configured to be attachable to an edge of the upper opening of the tank main body. The attachment member includes a receiving part in which a recessed part for receiving the chemical solution that drips from the chemical container is formed. In a bottom portion of the recessed part is formed a discharge hole to which the tube is connected.

Claims (24)

1. A chemical feeding device for attaching to a bowl of a toilet, comprising:

a chemical container storing a chemical solution;

a flexible tube through which the chemical solution in the chemical container is fed to an inside of the toilet bowl; and

an attachment member that supports the tube and is configured to be attachable to a rim of the toilet bowl,

wherein the attachment member includes a receiving part in which a recessed part for receiving the chemical solution that drips from the chemical container is formed,

in a bottom portion of the recessed part is formed a discharge hole to which the tube is connected, and

the tube is supported to be located lower than the discharge hole by the attachment member.

2. The chemical feeding device according to claim 1 ,

wherein the attachment member includes:

an abutting part capable of abutting an outer surface of the rim of the toilet bowl; and

a fixing part that, in an initial state, straddles the rim of the toilet bowl from the abutting part and extends downward along an inner wall surface of the toilet bowl.

3. The chemical feeding device according to claim 2 , wherein the fixing part is formed with a flexible material and, in the initial state, curves upward in a convex shape.

an attachment member that supports the tube and is configured to be attachable to an edge of the upper opening of the tank main body,

wherein the attachment member includes a receiving part in which a recessed part for receiving the chemical solution that drips from the chemical container is formed,

in a bottom portion of the recessed part is formed a discharge hole to which the tube is connected, and

the tube is supported to be located lower than the discharge hole by the attachment member.

5. The chemical feeding device according to claim 4 , wherein the attachment member includes:

an abutting part capable of abutting an outer surface of the tank main body; and

a fixing part that, in an initial state, straddles the edge of the tank main body from the abutting part and extends downward along an inner surface of the tank main body.

6. The chemical feeding device according to claim 5 , wherein the fixing part is formed with a flexible material and, in the initial state, curves upward in a convex shape.

7. The chemical feeding device according to claim 5 , wherein at an upper portion of the abutting part is formed an installation surface on which an edge extending downward from an outer peripheral edge of the lid body is installable.
