Just.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing of Fig. 1；
Fig. 3 is the partial structurtes schematic diagram of outer cylinder body.
Detailed description of the invention:
Embodiment: as shown in Fig. 1 is to 3, a kind of modified model powerroof ventilator, including motor 1,
Impeller 2 and frame 3, described frame 3 structure is that the bottom surface of base plate 31 is fixed with base 32,
There is on base 32 air intake duct 321, base plate 31 forms air inlet 311, air inlet 311
Communicating with air intake duct 321, bellows 33 are fixed on base plate 31, bellows 33 are fixed with dynamic
Power case 34, motor 1 is fixed on the top board of bellows 33, motor 1 in headstock 34,
Being fixed with impeller 2 on the output shaft of motor 1, impeller 2 is in bellows 33, annular sidewall
35 are fixed on base plate 31, and annular sidewall 35 cross section is the arc-shaped of middle part outwardly convex,
Bellows 33 are in annular sidewall 35；
There is on the sidewall of bellows 33 multiple through hole 331, through hole 331 and air inlet 311 phase
Logical, the top board of bellows 33 has multiple vertical through hole 332, vertical through hole 332 and power
Case 34 communicates, and the sidewall of headstock 34 has multiple horizontal vent 341, headstock 34
Top board on be fixed with top cover 36, the edge of top cover 36 has the rib 361 downwardly extended；
Bellows 33 upper sleeve has outer cylinder body 4, the sidewall of outer cylinder body 4 has multiple cross section and is
