Abstract
The invention relates to a sonotrode for the ultrasonic welding of plastic components of an electronic cigarette. The sonotrode comprises: a body comprising a first end which can be connected to an ultrasound generator, and a second end; a cavity that develops from the second end towards the first end, for receiving at least partially a plastic component of an electronic cigarette to be welded. The cavity defines an opening at the second end of the body, communicating with the outside of the sonotrode. In particular, at the opening, the cross section of the cavity has an outline comprising: a first portion that has the shape of a first arc of a reference circumference, which comprises a first end and a second end, opposite each other; and a second portion, that has the shape of a second arc of said reference circumference, which comprises a first end and a second end, opposite each other. The aforementioned outline further comprises: a third portion, connected to the first end of the first portion and to the first end of the second portion, which develops externally with respect to the reference circumference; and a fourth portion, connected to the second end of the first portion and to the second end of the second portion, which develops externally with respect to said reference circumference.
