         3 . The dust collection device of  claim 2 , wherein a shape of a portion of the opening/closing cover is formed to correspond to a shape of the inclined portion. 
     
     
         4 . The dust collection device of  claim 2 , wherein a portion of the opening/closing cover in contact with the inclined portion is made of an elastic material. 
     
     
         5 . The dust collection device of  claim 2 , wherein a portion of the opening/closing cover in contact with the inclined portion is provided with an elastic member. 
     
     
         6 . The dust collection device of  claim 1 , wherein the opening/closing cover opens the opening of the support plate upon pressure being applied along a protruding direction of the protrusion rib. 
     
     
         7 . The dust collection device of  claim 1 , wherein the opening/closing cover closes the opening of the support plate upon pressure being applied along a direction opposite to a protruding direction of the protrusion rib. 
     
     
         8 . The dust collection device of  claim 1 , wherein the opening/closing cover is made of an elastic material. 
     
     
         9 . The dust collection device of  claim 1 , wherein the support plate comprises a transparent portion configured to allow light to pass therethrough. 
     
     
         10 . The dust collection device of  claim 1 , wherein the opening has a circular shape. 
     
     
         11 . The dust collection device of  claim 1 , wherein the dust collection device is configured to enable a dust bag to be coupleable to and decouplable from the dust collection device, and
 a direction in which the protrusion rib extends is along a direction facing the dust bag while the dust bag is coupled to the dust collection device.   
     
     
         12 . A dust collection station, comprising:
 a seating portion to receive a dust collecting container of a vacuum cleaner;   a dust collection device below the seating portion, the dust collection device being configured to allow a dust bag to be mounted; and   a suction device below the dust collection device, the suction device being configured to generate a suction airflow in a direction from the seating portion toward the dust collection device,   wherein the dust collection device comprises:
 a support plate including a protrusion rib formed to extend from one surface of the support plate, and an opening through which the dust collecting container is connectable; and 
 an opening/closing cover configured to open or close the opening of the support plate while one side of the opening/closing cover is fixed to the support plate, the opening/closing cover being configured to be spaced apart from the protrusion rib to open the opening and to be in contact with the protrusion rib to close the opening, 
   wherein the protrusion rib extends more at a first point that is further from the one side of the opening/closing cover fixed to the support plate than a second point closer to the one side of the opening/closing cover.   
     
     
         13 . The dust collection station of  claim 12 , wherein the opening/closing cover opens the opening while the suction device operates. 
     
     
         14 . The dust collection station of  claim 12 ,
 wherein the protrusion rib comprises an inclined portion formed to connect the first point and the second point, and   wherein the opening is closed while the inclined portion is in contact with one surface of the opening/closing cover.   
     
     
         15 . The dust collection station of  claim 12 , wherein the opening/closing cover is made of an elastic material. 
     
     
         16 . The dust collection station of  claim 12 , wherein the support plate comprises a transparent portion configured to allow light to pass therethrough. 
     
     
         17 . A cleaning device comprising:
 a vacuum cleaner including a dust collecting container in which a foreign substance is to be collected; and   a dust collecting station connectable to the dust collecting container of the vacuum cleaner so as to allow the foreign substance collected in the dust collecting container to be removed,   wherein the dust collection station comprises:
 a seating portion to receive the dust collecting container; 
 a dust collection device below the seating portion, the dust collection device being configured to allow a dust bag to be mounted; and 
 a suction device below the dust collection device, the suction device being configured to generate a suction airflow in a direction from the seating portion toward the dust collection device, 
   wherein the dust collection device comprises:
 a support plate including a protrusion rib formed to extend from one surface of the support plate, and an opening through which the dust collecting container is connectable; and 
 an opening/closing cover configured to open or close the opening of the support plate while one side of the opening/closing cover is fixed to the support plate, the opening/closing cover being configured to be spaced apart from the protrusion rib to open the opening and to be in contact with the protrusion rib to close the opening, 
   wherein the foreign substance collected in the dust collecting container pass through the opening to be collected into the dust bag, while the opening/closing cover operates to be open the opening in response to generation of the suction airflow.   
     
     
         18 . The cleaning device of  claim 17 , wherein the protrusion rib extends more at a first point that is further from the one side of the opening/closing cover fixed to the support plate than a second point closer to the one side of the opening/closing cover.
