Cleaner head

Abstract

A cleaner head includes a housing part having an opening opened downwardly, a vibration generating part disposed to cover the opening, and having at least one inlet passing through an inhaling force to generate a vibration force, a brush part disposed under the vibration generating part, and receiving the vibration force to vibrate, and a vibration isolating part disposed around the housing part, and separating the vibration generated by the vibration generating part from the housing part.

What is claimed is: 
     
         1 . A cleaner head comprising:
 a housing part having an opening opened downwardly;   a vibration generating part disposed to cover the opening, having at least one inlet passing through an inhaling force and being configured to generate a vibration force;   a brush part disposed under the vibration generating part, and being configured to receive the vibration force to vibrate; and   a vibration isolation part disposed around the housing part, and being configured to vibrationally isolating the housing part from the vibration generating part.   
     
     
         2 . The cleaner head of  claim 1 , wherein the vibration isolating part is interposed between the housing part and the vibration generating part. 
     
     
         3 . The cleaner head of  claim 1 , wherein the vibration isolating part has a closed curve shape along a lower surface of the housing in a plan view. 
     
     
         4 . The cleaner head of  claim 1 , wherein the vibration isolating part comprises a rubber material or a high polymer resin material. 
     
     
         5 . The cleaner head of  claim 1 , wherein the vibration isolating part has a U-shaped vertical cross-section. 
     
     
         6 . The cleaner head of  claim 1 , wherein the vibration generating part comprises:
 a vibration plate covering the opening and having the inlet;   an oscillator disposed on the vibration plate; and   a motor connected to the oscillator on the vibration plate by a link to provide a driving force to the oscillator.   
     
     
         7 . The cleaner head of  claim 6 , wherein the vibration plate has a pair of inlets having different areas from each other. 
     
     
         8 . The cleaner head of  claim 1 , further comprising a first coupling member fixing the vibration isolating part to a lower surface of the housing part. 
     
     
         9 . The cleaner head of  claim 8 , wherein the first coupling member comprises a hook. 
     
     
         10 . The cleaner head of  claim 1 , further comprising a handle part configured to be connected to an upper portion of the housing part and having a flow path formed inside thereof. 
     
     
         11 . The cleaner head of  claim 10 , wherein the handle part comprises:
 A battery provided therein and being configured to supply an electric power to the vibration generating part; and   a controller controlling a power supply from the battery to the vibration generating part.   
     
     
         12 . The cleaner head of  claim 11 , wherein the handle part further comprises a sensor configured to sense a pressure in the flow path to provide a pressure signal to the controller. 
     
     
         13 . The cleaner head of  claim 10 , wherein the handle part further comprises a second connecting part having an end portion configured to be connected to an extension hose. 
     
     
         14 . The cleaner head of  claim 10 , wherein the housing part comprises:
 a housing body having the opening; and   a connector connecting the housing body and the handle part to each other.   
     
     
         15 . The cleaner head of  claim 14 , wherein the connector is rotatably connected to the handle part along an inclined direction with respect to an extension direction of the housing body.
