Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1 shown in -3, a kind of centrifugal blower freely adjusting air-out direction described in the utility model, including pedestal 1,
Fan casing 2 and the impeller 3 in Fan casing 2, wherein impeller 3 mainly includes the fixed ring 301 and fixed plate for being divided into both ends
302, with several blades 303 of annular array between fixed ring 301 and fixed plate 302, wherein impeller 3 is connected with motor
4；Fan casing 2 is horizontally disposed cylindrical shape；The left end of Fan casing 2 has air inlet 201；Have on the arc surface of Fan casing 2
One air outlet 202；Two bearings 5 are also symmetrically arranged in the arc-shaped surface of Fan casing 2；It is solid that 5 lower end of bearing passes through fixed plate 6
It is scheduled on pedestal 1；It is additionally provided with the snap-gauge 7 of one section of arc-shaped in the arc-shaped surface of the centre of Fan casing 2, wherein has on snap-gauge 7
Several through-holes 8；A sliding rail 9 axial along Fan casing 2 is fixedly connected among 1 upper surface of pedestal；It is slidably connected on sliding rail 9
Sliding block 10；Wherein sliding rail 9 is arranged to isosceles trapezoidal structure wide at the top and narrow at the bottom, and sliding block 10 is adapted with the sliding rail 9, so as to prevent
