FIELD: personal use articles. ^ SUBSTANCE: invention relates to nozzle for cleaning device, in particular, vacuum cleaner. Nozzle (10; 100) for cleaning device comprises head (12; 112) with suction hole (20a, 20b; 112b) and journal (11; 111), comprising middle section (14; 114) and end section (16; 116) for connection with output end of rigid adapter or hose. End section comprises longitudinal axis (X-X). Besides, nozzle comprises the first rotary joint (18; 118), having the first axis of rotation (X'-X'; X"-X") and arranged between end section and middle section (14; 114), and the second rotary connection (26; 126), having the second axis of rotation (Y'-Y'; Y"-Y") and arranged between head (12; 112) and middle section (14; 114). Each rotary joint (18, 26; 118, 126) allows for mutual displacement of end section and head (12; 112). Axis (X'-X'; X"-X") of rotation of the first rotary joint (18; 118) is arranged at the angle to longitudinal axis (X-X) of end section. Due to the first rotary joint (18; 118), having axis (X'-X'; X"-X") of rotation, arranged at the angle to longitudinal axis (X-X) of end section, head (12; 112) of nozzle (10; 100) may be displaced into multiple convenient positions to facilitate cleaning of walls and horizontal surfaces located at large height. ^ EFFECT: development of nozzle for cleaning device, which allows for more flexible alignment of suction hole relative to rigid adapter or hose compared to available nozzles. ^ 16 cl, 9 dwg |
