Abstract

A vacuum cleaner includes a cleaner body, a connection pipe including a first catching groove, and a suction nozzle. The suction nozzle includes a connection neck, a nozzle housing rotatably coupled to the connection neck, a first catching body rotatably coupled to the connection neck, and a first elastic body. The first catching body includes a first catching protrusion portion which is caught by the first catching groove. The suction nozzle includes a pressing portion and a first lever. The first lever includes a first end portion in contact with the pressing portion, and a second end portion configured to press the first catching body. According to the disclosed vacuum cleaner, the fastening between the suction nozzle and the connection pipe may be maintained or released according to the relative angle between the suction nozzle and the connection pipe.

A vacuum cleaner comprising:

a cleaner body including a body suction port;
a connection pipe coupled to the body suction port;
and
a suction nozzle configured to be selectively coupled to or separated from an end of the connection pipe,
wherein:
the connection pipe includes a catching groove,
the suction nozzle includes:
a connection neck that is selectively coupled to or separated from the end of the connection pipe;
and
a first latch coupled to the connection neck and including a catching protrusion which engages the catching groove when the connection neck is coupled to the end of the connection pipe, and
