Abstract:

The present invention relates to a vacuum cleaner station. A channel switching module according to the present invention comprises: a case; a connection hose which has a slot that moves along the inner circumference of the case, and which is selectively coupled to either a first vacuum cleaner channel connection part or a second vacuum cleaner channel connection part; a switching motor, which is disposed at one side of the case and generates power; a drive cam, which is coupled to the switching motor, includes a sensing unit protruding to one side and transmits power to the connection hose; and a position sensor which is disposed at one side of the sensing unit, and which includes a switch turned on or off by means of the sensing unit, so as to detect the position of the connection hose, and thus, even if a user does not directly reassemble the connection hose, the vacuum cleaner station has a first link and a second link that move the connection hose so that it can be easily determined whether the connection hose is coupled to the first vacuum cleaner channel connection part or the second vacuum cleaner channel connection part and, simultaneously, whether the connection hose is coupled to the first vacuum cleaner channel connection part or the second vacuum cleaner channel connection part.
