Abstract
The utility model relates to a centrifugal air exhauster with multiple air outlets. The utility model is characterized in that a vane wheel is arranged in a casing body; the center of one side surface of the casing body is provided with an air suction opening, the other side surface is fixedly provided with a motor, and the motor drives the vane wheel to rotate; the casing body is provided with a plurality of air outlet pipes, and the axial direction of each air outlet pipe is respectively symmetrical to the tangential direction of the vane wheel. When the motor drives the vane wheel to rotate, air can be sucked in from the air suction opening and is vented from each air outlet pipe then. The utility model has better operation and air collection efficiency.
Description
The utility model relates to a kind of induced draft fan, particularly relates to a kind of centrifugal air port induced draft fan that has more.
As shown in Figure 1, general induced draft fan is to be provided with a Vane wheel 5 housing 4 inside, on a wherein side of this housing 4, be installed with a motor 6, the axle of this motor 6 and Vane wheel 5 are affixed, and central authorities form an air sucking mouth 41 in the another side, and extend an air outlet tube 42 in these housing 4 peripheral pre-positions, the tangent direction symmetry of axial and this Vane wheel 5 of this air outlet tube 42, therefore, when starting this motor 6 and drive Vane wheel 5 rotations, air can suck these housing 4 inside by air sucking mouth 41, and is subjected to the centrifugal action that this Vane wheel 5 rotates, can be along these air outlet tube 42 outputs.But this induced draft fan because 1 of this housing is provided with an air outlet tube 42, can't reach preferable exhausting efficient in use.
The purpose of this utility model is to provide a kind of centrifugal air port induced draft fan that has more that can strengthen air-supply efficient.
Above-mentioned purpose realizes by the following technical solutions: a kind of centrifugal air port induced draft fan that has more, comprise that a housing is provided with a holding space an enclosure interior, Vane wheel of installing in this holding space, and be symmetrical in the axial housing of this Vane wheel wherein side central authorities set firmly a motor, make the axle and the Vane wheel of this motor affixed, and the another side is provided with an air sucking mouth, be formed with the air outlet tube of predetermined number at this housing periphery, the tangent direction that axially all is symmetrical in this Vane wheel of each air outlet tube, and form an exhaust outlet endways, this exhaust outlet and holding space are the perforation shape, so, this motoring Vane wheel rotates and when producing air drafting effect, air can be sucked in holding space by this air sucking mouth, and be subjected to that this Vane wheel is agitated and tangential each air outlet tube output, so compare with the general induced draft fan that has only an exhaust outlet, the centrifugal exhausting efficient that has more the air port induced draft fan of the present utility model will improve many.
Below by most preferred embodiment and accompanying drawing the centrifugal air port induced draft fan that has more of the present utility model is elaborated, in the accompanying drawing:
Fig. 1 is the schematic perspective view of induced draft fan in the past.
Fig. 2 is the schematic perspective view of the utility model one preferred embodiment.
Fig. 3 is the combination section of the above-mentioned preferred embodiment of the utility model.
Fig. 4 is the combination section of another preferred embodiment of the utility model.
Shown in Fig. 2,3, the centrifugal air port induced draft fan that has more of the present utility model comprises a housing 10, a Vane wheel 20 and a motor 30.
This housing 10 is hollow short cylindrical shape, holding space 11 of inner formation, at these holding space 11 upper and lower side symmetry places, each is straight extends an air outlet tube 12,13, the end of each air outlet tube 12,13 is formed with an exhaust outlet 121,131 that interpenetrates with this holding space 11 again, make this two exhaust outlet 121,131 be opposite direction, and wherein be provided with a circular hole 14 in a side at this housing 10, the relative position place of another side is provided with an air sucking mouth 15, and this circular hole 14 all can connect to this holding space 11 with air sucking mouth 15.
This Vane wheel 20 was with member was identical in the past, and was installed in this holding space 11 inside, and these Vane wheel 20 central authorities are provided with an axis hole 21, this axis hole 21 and circular hole 14 symmetries, and be provided with most blades 22.
This motor 30 is installed in this housing 10 wherein on the side, and this circular hole 14 is sealed, and the axle 31 of this motor 30 is to penetrate and be fixed in the axis hole 21 of this Vane wheel 20 from this circular hole 14, rotates to drive this Vane wheel 20.
As shown in Figure 3, when starting this motor 30, this Vane wheel 20 just rotates toward specific direction, and the tangent direction when this Vane wheel 20 rotates is and this air outlet tube 12,13 symmetries, so, when this Vane wheel 20 rotate and the air that will be present in these housing 10 holding spaces 11 inside originally by this air outlet tube 12,13 when bloating, at low pressure area of these holding space 11 inner formation, extraneous air can promptly be sucked in this holding space 11 inside by this air sucking mouth 15, and be subjected to the effect of agitating of these Vane wheel 20 blades 22, can be thrown away by centrifugal along the periphery tangent direction of this Vane wheel 20, and by this air outlet tube 12,13 outputs are so present embodiment has this two air outlet tube 12, the exhausting effect of 13 while exhausting.
As shown in Figure 4, it is another preferred embodiment of the utility model, be four symmetrical position places at these housing 101 peripheries, form four air outlet tubes 1011,1021,1031,1041 altogether, and each air outlet tube 1011,1021,1031,1041 axially all with the periphery tangent direction symmetry of this Vane wheel 201, and two adjacent air outlet tubes axially all be the square crossing shape, therefore, can obtain four air outlet tubes 1011,1021,1031,1041 exhausting effect of exhausting simultaneously simultaneously.
