Title: Sponge filter material equipped with water flow inhibitor
Inventor: SUDA KAZUTOSHI
IPC: A01K63/04
Filed: 2017-07-11
Abstract: To solve problems in a conventional filtration device generally named as a sponge filter in which the height of a main body is high and water is absorbed from all directions on the surface of a filter material, and therefore the efficiency is lowered when a large filter material is attached and it cannot be used in the low water depth.SOLUTION: A water flow inhibitor is attached on the surface where the filtration efficiency is decreased due to the occurrence of water flow of a filter material, and thereby a filtration volume can be used without any waste. As a result, the filtration efficiency is not lowered even if used in the low water depth, and can be increased while the height of the filter material is being suppressed. As a result, the design of suppressing an overall height becomes possible, and efficient filtration can be performed even in the low water depth.SELECTED DRAWING: Figure 1
