Water absorbing structure and brush assembly using the same

Abstract

A water absorbing structure and a brush assembly using the same are provided. The water absorbing structure contains no less than 30% by weight of diatomaceous earth based on a total weight of the water absorbing structure, and includes a block body and a protruding pattern. The block body has a first surface and a second surface opposite to the first surface. The protruding pattern is formed on the first surface of the block body and configured to contact and squeeze a brush head of a brush.

What is claimed is: 
     
         1 . A water absorbing structure for use with a brush, comprising:
 a block body having a first surface and a second surface opposite to the first surface; and   a protruding pattern formed on the first surface of the block body and configured to contact and squeeze a brush head of the brush;   wherein the water absorbing structure contains no less than 30% by weight of diatomaceous earth based on a total weight of the water absorbing structure.   
     
     
         2 . The water absorbing structure according to  claim 1 , wherein the block body has a disc shape. 
     
     
         3 . The water absorbing structure according to  claim 1 , wherein the protruding pattern includes at least one first protruding portion, at least one second protruding portion, and at least one third protruding portion that are in a concentric arrangement. 
     
     
         4 . The water absorbing structure according to  claim 3 , wherein the at least one first protruding portion, the at least one second protruding portion, and the at least one third protruding portion are different in width. 
     
     
         5 . The water absorbing structure according to  claim 1 , further comprising a recessed pattern that is formed on the second surface of the block body. 
     
     
         6 . The water absorbing structure according to  claim 5 , wherein the recessed pattern includes at least one first recessed portion, at least one second recessed portion, and at least one third recessed portion that are parallel to and spaced apart from each other. 
     
     
         7 . The water absorbing structure according to  claim 6 , wherein the at least one first recessed portion, the at least one second recessed portion, and the at least one third recessed portion are different in length. 
     
     
         8 . The water absorbing structure according to  claim 6 , wherein each of the at least one first recessed portion, the at least one second recessed portion, and the at least one third recessed portion tapers in width from a central section thereof toward two opposite end sections thereof. 
     
     
         9 . A brush assembly, comprising:
 a brush including a holding portion and a brush head disposed at a front end of the holding portion; and   a water absorbing structure configured for use with the brush, the water absorbing structure including:
 a block body having a first surface and a second surface opposite to the first surface; and 
 a protruding pattern formed on the first surface of the block body and configured to contact and squeeze the brush head of the brush; 
   wherein the water absorbing structure contains no less than 30% by weight of diatomaceous earth based on a total weight of the water absorbing structure.   
     
     
         10 . The brush assembly according to  claim 9 , wherein the block body has a disc shape. 
     
     
         11 . The brush assembly according to  claim 9 , wherein the protruding pattern includes at least one first protruding portion, at least one second protruding portion, and at least one third protruding portion that are in a concentric arrangement. 
     
     
         12 . The brush assembly according to  claim 11 , wherein the at least one first protruding portion, the at least one second protruding portion, and the at least one third protruding portion are different in width. 
     
     
         13 . The brush assembly according to  claim 9 , wherein the water absorbing structure further includes a recessed pattern that is formed on the second surface of the block body. 
     
     
         14 . The brush assembly according to  claim 13 , wherein the recessed pattern includes at least one first recessed portion, at least one second recessed portion, and at least one third recessed portion that are parallel to and spaced apart from each other. 
     
     
         15 . The brush assembly according to  claim 14 , wherein the at least one first recessed portion, the at least one second recessed portion, and the at least one third recessed portion are different in length. 
     
     
         16 . The brush assembly according to  claim 14 , wherein each of the at least one first recessed portion, the at least one second recessed portion, and the at least one third recessed portion tapers in width from a central section thereof toward two opposite end sections thereof.
