Noise reducing apparatus, for floating humidifier, using cap

Abstract

Provided is an apparatus for reducing noise of a floating-type humidifier by using a cap. The apparatus for reducing the noise of the floating-type humidifier by using the cap includes a water tank lid coupled to an upper portion of a water tank in which the floating-type humidifier is floated and having an opening, through which a portion of the floating-type humidifier is exposed, in an upper portion thereof and a cap having a predetermined height along a circumference of the opening to reduce an amount of air introduced into the floating-type humidifier. The cap is provided with a through-part, through which a portion of the exposed floating-type humidifier passes, in an upper portion thereof.

1 . An apparatus for reducing noise of a floating-type humidifier by using a cap, the apparatus comprising:
 a water tank lid coupled to an upper portion of a water tank in which the floating-type humidifier is floated and having an opening, through which a portion of the floating-type humidifier is exposed, in an upper portion thereof; and   a cap having a predetermined height along a circumference of the opening to reduce an amount of air introduced into the floating-type humidifier,   wherein the cap is provided with a through-part, through which a portion of the exposed floating-type humidifier passes, in an upper portion thereof.   
     
     
         2 . The apparatus of  claim 1 , wherein the water tank lid includes an inclined part of which a top surface is inclined downward toward the opening. 
     
     
         3 . The apparatus of  claim 1 , wherein the through-part has a diameter greater than that of a discharge part of the floating-type humidifier to provide a spaced space between the cap and a circumference of the floating-type humidifier passing through the cap. 
     
     
         4 . The apparatus of  claim 3 , wherein the cap further includes a plurality of protrusions, each of which protrudes by a predetermined size through the spaced space along a circumference of the through-part. 
     
     
         5 . The apparatus of  claim 4 , wherein the plurality of protrusions horizontally protrudes toward the opening along the circumference of the through-part. 
     
     
         6 . The apparatus of  claim 4 , wherein the plurality of protrusions protrudes to be inclined toward the opening along the circumference of the through-part. 
     
     
         7 . The apparatus of  claim 4 , wherein the plurality of protrusions is spaced a uniform interval from each other along the circumference of the through-part, and
 the interval is an interval at which the plurality of protrusions is spaced an angle of about n/360 degrees (where n is the number of plurality of protrusions) from each other with respect to a center of the through-part.   
     
     
         8 . The apparatus of  claim 3 , wherein the opening has at least one recessed groove that is recessed by a predetermined size along the circumference thereof so that humidified particles discharged from the floating-type humidifier and sunken on the top surface of the water tank lid are reintroduced into the water tank. 
     
     
         9 . The apparatus of  claim 3 , wherein the cap is detachably coupled to the opening. 
     
     
         10 . The apparatus of  claim 9 , wherein the cap further includes a seating part extending upward from a lower circumference of the cap and inclined to the outside of a central axis of the through-part so that the cap is seated on a circumferential portion of the opening. 
     
     
         11 . The apparatus of  claim 10 , wherein the cap further includes at least one discharge hole defined in the lower circumference of the cap so that the humidified particles discharged from the floating-type humidifier and sunken on the top surface of the water tank lid are reintroduced into the water tank.
