Dust collecting equipment

Abstract

A cleaner includes a dust separation unit which separates dust from sucked air; a dust container which stores the dust separated by the dust separation unit; a first suction port through which an external air is sucked into the dust separation unit; a second suction port through which the external air is sucked into the dust separation unit; a discharge port through which air inside the dust separation unit is discharged; and a flow path blocking member which selectively covers the first suction port and the second suction port.

What is claimed is: 
     
         1 . A cleaner comprising:
 a dust separation unit which separates dust from sucked air;   a dust container which stores the dust separated by the dust separation unit;   a first suction port through which an external air is sucked into the dust separation unit;   a second suction port through which the external air is sucked into the dust separation unit;   a discharge port through which air inside the dust separation unit is discharged; and   a flow path blocking member which selectively covers the first suction port and the second suction port.   
     
     
         2 . The cleaner of  claim 1 , wherein the flow path blocking member reciprocates between a first position for covering the first suction port and a second position for covering the second suction port. 
     
     
         3 . The cleaner of  claim 1 , further comprising a lever which is connected to the flow path blocking member and at least a part of the lever is exposed to the outside of the dust container. 
     
     
         4 . The cleaner of  claim 1 , wherein the first suction port and the second suction port are formed on a lateral surface of the dust container. 
     
     
         5 . The cleaner of  claim 2 , further comprising:
 a movement guide which guides movement of the flow path blocking member; and   an elastic member which provides an elastic force to return the flow path blocking member to the second position.   
     
     
         6 . The cleaner of  claim 1 , wherein the flow path blocking member restricts a coupling of a cleaning nozzle for manual cleaning coupled to the second suction port, when the flow path blocking member is located in a second position. 
     
     
         7 . The cleaner of  claim 1 , wherein the flow path blocking member allows a coupling of a cleaning nozzle for manual cleaning coupled to the second suction port, when the flow path blocking member is located in a first position. 
     
     
         8 . The cleaner of  claim 1 , wherein a coupling unit for coupling a cleaning nozzle for manual cleaning is formed around the second suction port,
 wherein the flow path blocking member covers at least a part of the coupling unit when the flow path blocking member is located in a second position.   
     
     
         9 . The cleaner of  claim 8 , wherein the flow path blocking member exposes the coupling unit when the flow path blocking member is positioned in a first position. 
     
     
         10 . The cleaner of  claim 5 , wherein an elastic return of the flow path blocking member to the second position is restricted by a cleaning nozzle for manual cleaning coupled to the second suction port. 
     
     
         11 . The cleaner of  claim 5 , wherein the flow path blocking member returns to the second position due to the elastic force of the elastic member, when the coupling of the cleaning nozzle for manual cleaning coupled to the second suction port is released. 
     
     
         12 . The cleaner of  claim 5 , further comprising an actuator which moves the flow path blocking member to the first position. 
     
     
         3 . The cleaner of  claim 12 , further comprising a coupling sensor which detects that a cleaning nozzle for manual cleaning is coupled to the second suction port,
 wherein the actuator moves the flow path blocking member to the first position when the cleaning nozzle for manual cleaning is coupled to the second suction port.   
     
     
         14 . The cleaner of  claim 12 , further comprising a coupling sensor which detects that a cleaning nozzle for manual cleaning is coupled to the second suction port,
 wherein the actuator moves the flow blocking member to the second position when the cleaning nozzle for manual cleaning is disconnected from the second suction port.   
     
     
         15 . The cleaner of  claim 1 , wherein the flow path blocking member has the same curvature, within a certain error range, as a curvature of an inner surface or an outer surface of a lateral surface of the dust container.
