         2 . The suction device of  claim 1 , wherein the closure element is movably mounted on the suction device housing for adjustment between the supply receptacle and the suction inlet by means of a bearing. 
     
     
         3 . The suction device of  claim 2 , wherein the bearing is or comprises a swivel bearing for pivotally supporting the closure element about a swivel axis. 
     
     
         4 . The suction device of  claim 2 , wherein the closure body and a bearing projection or a bearing receptacle of the bearing are arranged on an arm body of the closure element. 
     
     
         5 . The suction device of  claim 4 , wherein the arm body has a plate-like or wall-like shape. 
     
     
         6 . The suction device of  claim 4 , wherein the closure body and the bearing are arranged on opposite longitudinal end regions of the arm body. 
     
     
         7 . The suction device of  claim 4 , wherein the closure body and a bearing projection of the bearing project to the same side of the arm body in the direction of the suction device housing. 
     
     
         8 . The suction device of  claim 4 , wherein the arm body is flexible transversely to its longitudinal axis extending between the bearing and the closure body in such a way that it is deformable transversely to the longitudinal axis out of the supply receptacle or into the supply receptacle or out of the suction inlet and into the suction inlet. 
     
     
         9 . The suction device of  claim 1 , wherein the supply receptacle and/or the suction inlet are configured as plug-in receptacles. 
     
     
         10 . The suction device of  claim 1 , wherein the closure body has on its outer circumference at least one seal for sealing abutment against a circumferential wall of the suction inlet and/or for clamping abutment against a circumferential wall of the supply receptacle. 
     
     
         11 . The suction device of  claim 1 , wherein the closure element has a grip handle for actuating the closure body into the supply receptacle or out of the supply receptacle. 
     
     
         12 . The suction device of  claim 11 , wherein the grip handle is arranged in an inner space of the closure body. 
     
     
         13 . The suction device of  claim 11 , wherein the grip handle has mutually opposite side walls, which can be gripped in the manner of a clamping grip or a pincer grip and/or are actuatable towards each other by means of a clamping actuation, in order to reduce or eliminate a clamping seat of the closure body in the supply receptacle or the suction inlet. 
     
     
         14 . The suction device of  claim 1 , further comprising a dust collecting container, which is arranged in the dust collecting chamber or which provides the dust collecting chamber, which can be removed from the suction device housing. 
     
     
         15 . The suction device of  claim 1 , wherein the closure element is arranged on an outer wall of the suction device housing. 
     
     
         16 . The suction device of  claim 1 , further comprising a closure element receptacle for receiving the closure element. 
     
     
         17 . The suction device of  claim 16 , wherein a depth of the closure element receptacle of the suction device is at least equal to a height of the part of the closure element which is received in the closure element receptacle, such that the closure element does not protrude in front of a surface of the outer wall, when it is received in the closure element receptacle. 
     
     
         18 . The suction device of  claim 1 , wherein the suction device housing is configured as a stack housing, which is designed in order to form a housing stack which extends in the direction of the stacking axis, underneath of which at least one stacking container or atop of which at least one stacking container can be stacked. 
     
     
         19 . The suction device of  claim 18 , further comprising coupling means for coupling the suction device housing to a stacking container, which is stacked atop or underneath along the stacking axis, wherein the coupling means of the suction device are configured to interact with coupling means of the stacking container, so that the suction device housing is firmly connected with the stacking container by means of the coupling means transversely to the stacking axis and parallel to the stacking axis. 
     
     
         20 .
