Air purifier

Abstract

The air purifier includes: a body having an inlet formed on a circumferential surface thereof and an outlet formed on an upper surface thereof; and a booster disposed on the body and switching a flow direction of air which flows from the body through the outlet. The booster includes a booster case having a booster inlet and a booster outlet, a booster fan disposed in the booster case, and forming air flowing from the booster inlet to the booster outlet, and a fan housing in which the booster fan is rotatably disposed. The booster case includes a circumference body disposed on a circumference of the fan housing and guiding air discharged from the fan housing, and a rear body disposed at one side of the circumference body and having the booster inlet. The fan housing is coupled to the rear body by penetrating the circumference body.

What is claimed is: 
     
         1 . An air purifier comprising:
 a body having an inlet formed on a circumferential surface thereof and an outlet formed on an upper surface thereof; and   a booster disposed on the body and switching a flow direction of air which flows from the body through the outlet,   wherein the booster includes:   a booster case having a booster inlet and a booster outlet,   a booster fan disposed in the booster case, and forming air flowing from the booster inlet to the booster outlet, and   a fan housing in which the booster fan is rotatably disposed,   wherein the booster case includes:   a circumference body disposed on a circumference of the fan housing and guiding air discharged from the fan housing, and   a rear body disposed at one side of the circumference body and having the booster inlet, and   wherein the fan housing is coupled to the rear body by penetrating the circumference body.   
     
     
         2 . The air purifier of  claim 1 , wherein the circumference body is hook-coupled to the rear body. 
     
     
         3 . The air purifier of  claim 1 , wherein the circumference body includes a circumference wall disposed on the circumference of the fan housing, and a rear wall extended to an inner side in a rear of the circumference wall, and
 wherein a penetration hole penetrated by a partial configuration of the fan housing or the rear body is formed on the rear wall.   
     
     
         4 . The air purifier of  claim 3 , wherein the fan housing includes a fastening boss which protrudes to a rear on a rear surface of the fan housing, and
 wherein the fastening boss is coupled to the rear body by penetrating the penetration hole.   
     
     
         5 . The air purifier of  claim 3 , wherein the fan housing includes a locking jaw which protrudes to the rear on the rear surface of the fan housing, and is banded to an upper side, and
 wherein the locking jaw is inserted into a locking groove formed in the circumference body.   
     
     
         6 . The air purifier of  claim 5 , wherein the fan housing includes a terminal connector disposed to be spaced apart from the locking jaw and electrically connected to the body, and
 wherein a connection hole penetrated by the terminal connector is formed in the circumference body.   
     
     
         7 . The air purifier of  claim 6 , wherein the terminal connector is disposed in an opposite direction to the locking jaw. 
     
     
         8 . The air purifier of  claim 6 , wherein a direction in which the terminal connector protrudes from the fan housing is formed to be different from a direction in which the locking jaw protrudes from the fan housing. 
     
     
         9 . The air purifier of  claim 6 , wherein the locking jaw is bent in a direction opposite to the direction in which the terminal connector is disposed. 
     
     
         10 . The air purifier of  claim 1 , wherein the fan housing has a housing suction port formed in a direction of the rear body and a housing discharge port formed in a direction of the circumference body. 
     
     
         11 . The air purifier of  claim 1 , wherein a booster connector coupled to the body is disposed in the circumference body, and
 wherein the rear body has an opening formed in an area where the booster connector is disposed.   
     
     
         12 . The air purifier of  claim 1 , wherein the rear body has a shape of being convex to the rear, and
 wherein an inner surface of the rear body includes a contact rib which protrudes to the circumference body.   
     
     
         13 . The air purifier of  claim 12 , wherein the fan housing includes a locking jaw which protrudes to a rear of the circumference body through a locking groove formed in the circumference body, and
 wherein the contact rib is disposed to be in contact with one side of the locking jaw.   
     
     
         14 . The air purifier of  claim 1 , wherein the booster is separably disposed at an upper portion of the body. 
     
     
         15 . The air purifier of  claim 14 , wherein when the booster and the body are coupled to each other, the booster is electrically connected to the body.
