As shown in Figures 1 to 4, ventilation blower housing described in the utility model includes the first housing 1 and is covered on described first
The second housing 2 on housing 1；Fan base 11 is provided with first housing；The inwall of second housing 2, which convexes to form, leads
Aerofoil 212, the wind deflector 212 have the wind wheel room 214 of opening 2141 around being formed.In the present embodiment, the fan base
11 back side is provided with reinforcement 13, to strengthen the intensity of the fan base 11.
The wind deflector 212 of the ventilation blower housing is convexed to form by the inwall of second housing 2, the wind deflector
212 with second housing 2 be to be integrally formed, so the fixing end of the wind deflector 212 will not produce with second housing 2
Raw gap, and the free end of the wind deflector 212 is held in first housing 1, the first housing 1 is due to being provided with fan base
11, so can typically have flat surface, the free end of the wind deflector 212 is also not easy when being compressed with first housing 1
There is gap, reduce Air Leakage, reduce noise.
Further, the wind deflector 212 is in volute, is designed using equilateral primitive method, in the wind deflector 212 and benchmark
The distance of the heart constantly becomes big along clockwise direction, so that the flow velocity of air is from fast to slow, blast is uprised by low, makes the wind of air-flow
It is pressed in outlet port and reaches maximum.
Further, the outer wall of the wind deflector 212 is provided with ribs 22, the ribs 22 and second housing
2 inwall connection, to strengthen the intensity of the wind deflector 212, prevents the wind deflector 212 from being damaged because blast is excessive.It is excellent
Choosing, the ribs 22 are integrally formed with second housing 2.
Further, it is provided with fixing hole 221 at least one ribs 22, the fixing hole 221 and described the
The fixture of one housing 1 is (not shown) to be coordinated, and first housing 1 is fixed on second housing 2 by the fixture
On.By setting the fixing hole 221 in the ribs 22, the fixation set up and coordinated with the fixture again is avoided
Post, material is saved, reduce number of molds.
Further, one end of the wind deflector 212 is connected with module extender board 211, and the other end is connected with vortex tongue plate 213, institute
The air-guiding aisle 215 for being formed between module extender board 211 and the vortex tongue plate 213 and being connected with the opening 2141 is stated, by the wind wheel
Air-flow in room 214 exports from the opening 2141.In the present embodiment, the module extender board 211 and the vortex tongue plate 213 are same
It is integrally formed with second housing 2.
Optionally, the module extender board 211 and/or vortex tongue plate 213 is at least terminally positioned ribs 22, because
Maximum for blast herein, the module extender board 211 and/or the vortex tongue plate 213 are most also easy to produce shake, are damaged.
Further, the vortex tongue plate 213 is the segmental arc or oblique line section extended to the remote module extender board 211, so as to
The junction of the vortex tongue plate 213 and the wind deflector 212 is pointed so that the internal pinch of air-guiding aisle 215, outside wide, increasing
Big blast, make air supplying distance farther.
Further, the module extender board 211 is the straightway tangent with the wind deflector 212, reduce it is distinguished and admirable go out when receive
Resistance, while control the outflow direction of wind, it is not diverged, wind-force is more concentrated.In other embodiments, the straight line
Plate 211 can also be close gently towards the vortex tongue plate 213, to reduce the cross-sectional area of air-guiding aisle 215, further concentrates wind-force.
Further, arc flow distribution plate 24 is provided with the air-guiding aisle 215, the top of the arc flow distribution plate 24 is low
In the top of the module extender board 211 and the top of the vortex tongue plate 213.The arc flow distribution plate 24 changes the air-guiding aisle
The air flow direction at 215 tops, the air flow direction without influenceing the bottom of air-guiding aisle 215, make the outflow angle of the air-flow
It is wider, avoid air-flow from excessively concentrating, limited coverage area.In the present embodiment, the arc flow distribution plate 24 and the second shell
Body 2 is integrally formed.
Further, the arc flow distribution plate 24 is connected with the inwall of the module extender board 211, to close to the vortex tongue plate
213 extensions, so as to change the flow direction of the whole air-flows in the top of air-guiding aisle 215, make the air-flow for flowing to other directions more,
The intensity of even all directions air-flow.
Further, the outer wall of arc flow distribution plate 24 is provided with supporting plate 241, and the supporting plate 241 connects the arc
The inwall of the outer wall of shape flow distribution plate 24 and second housing 2.Strengthen the intensity of the arc flow distribution plate 24, prevent the arc point
Flowing plate 24 is damaged because blast is excessive.In the present embodiment, the supporting plate 241 is vertical with second housing 2.It is optional
, the end of at least described outer wall of arc flow distribution plate 24 is provided with ribs 22, because blast is larger herein, the arc shunting
Plate 24 is most vulnerable to damage or produces shake.
Further, the outer wall of the wind deflector 21 is provided with ribs 22, and the ribs 22 connect the wind deflector
The inwall of 21 outer wall and second housing 2, strengthen the intensity of the wind deflector 21, prevent the wind deflector 21 because blast
It is excessive and damage.In the present embodiment, the ribs 22 corresponding to the module extender board 211 and the wind deflector 212, one end connect
The wind deflector 21, the side wall of one end connection second housing 2 are connect, bottom is connected with the wall face of second housing 2, described
The corresponding ribs 22 of vortex tongue plate 213, one end connect the vortex tongue plate 213, other end connection wind deflector 212, bottom
It is connected with the wall face of second housing 2.Preferably, the ribs 22 are integrally formed with second housing 2.
Ventilation blower described in the utility model, including any one above-mentioned ventilation blower housing, and fan (not shown) and wind
Take turns (not shown), the fan (not shown) is installed on the fan base 11 and is connected with drive mechanism (not shown), described
Wind wheel 12 is covered on the fan and in the wind wheel room 214, as a result of any one above-mentioned ventilation blower housing,
So as to reduce the Air Leakage of the ventilation blower, noise is reduced.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
