Specific embodiment
A kind of air outlet flow guiding structure 13 is provided in one embodiment, as shown in Figures 1 to 4, including shell 131,
As shown in fig. 6, the shell 131 is located at 11 periphery of centrifugation blade, wind-guiding runner 132 is formed, is set in the wind-guiding runner 132
There is conducting element 133, the conducting element 133 is located at centrifugation blade 11 close to the side of 132 air outlet of wind-guiding runner, the conducting element
133 along the longitudinally disposed of wind-guiding runner 132.
Above scheme provides a kind of air outlet flow guiding structure 13, and under the action of centrifugation blade 11, air is from wind-guiding stream
It is passed through in road 132, as shown in figure 5, it is mobile in the shape of a spiral to air outlet in shell 131 by the air of centrifugation blade 11, and
As shown in fig. 6, being then oriented to the air moved in the shape of a spiral along the longitudinally disposed conducting element 133 of wind-guiding runner 132, make it
Longitudinal direction along wind-guiding runner 132 flows to air outlet, and air-flow is avoided to spin in wind-guiding runner 132, reduces wind loss, improves empty
Gas purification efficiency.
Specifically, conducting element 133 described herein refers under state as shown in Figure 6 along the longitudinally disposed of wind-guiding runner 132
Longitudinal direction, spiralling air is stopped by the conducting element 133, to be flowed up along conducting element 133, is kept away
Exempt to spin in inner casing 134, reduces wind loss.For example, shown in as shown in Figure 1, Figure 3 and Figure 4, in the front view of each embodiment
The visual part of the conducting element 133 is its end face.When the setting angle of clarifier 10 has offset, the conducting element 133
Setting direction also do respective offsets.But the relative position between the conducting element 133 and the shell 131 is constant, i.e. institute
Spiralling air-flow in the wind-guiding runner 132 can be oriented to by stating conducting element 133, make it substantially along shell 131
Axial movement.Specifically, the conducting element can be plate structure.Moreover, the number of the conducting element 133 can be set to it is more
It is a, to improve the barrier effect to spiral air, reduce wind loss.
And as shown in Figures 1 to 4, in one embodiment, the conducting element 133 is deflector, and the deflector is
Multiple, circumferentially uniform intervals are arranged multiple deflectors in the wind-guiding runner 132.So that sky spiralling in the axial direction
Gas can be guided by more uniform to air outlet, further increase air output.
As shown in figure 5, in one embodiment, the air outlet flow guiding structure 13 further includes being used to support motor 12
Inner casing 134, the inner casing 134 are located at centrifugation blade 11 close to the side of 132 air outlet of wind-guiding runner, the inner casing 134 with it is outer
The wind-guiding runner 132 is formd between shell 131, the conducting element 133 is between the inner casing 134 and shell 131.
When using the inner casing 134 support motor 12, the wind-guiding stream is formed between the inner casing 134 and shell 131
Road 132, then the conducting element 133 is arranged between the inner casing 134 and shell 131, rises to 132 inside spin of wind-guiding runner
Air is oriented to.
Specifically, the conducting element 133 can be connect with the shell 131, can also be connect with the inner casing 134.Or
Person is supported between shell 131 and inner casing 134, can play a supporting role to inner casing 134 and shell 131, improves air outlet and leads
The whole intensity of flow structure 13.For example, in one embodiment, as shown in Figures 1 to 4, the conducting element 133 is arranged described
On inner casing 134, and extend to the direction close to the shell 131, is connect with the shell 131.
Moreover, the presence based on the conducting element 133, when conducting element 133 is supported between inner casing 134 and shell 131,
Can set the structure with one fixed width for the conducting element 133, as shown in figure 4, then in conducting element 133 be arranged with
For the channel of cabling, to reduce the setting in special line channel between inner casing 134 and shell 131, it is further simplified structure.
As shown in figure 4, in one embodiment, the conducting element 133 is equipped with threading channel, and the threading channel is from described
The end face connecting on conducting element 133 with the shell 131 is through to the end face connecting with the inner casing 134.With the inner casing 134
The route that middle motor 12 connects then is connect by the threading channel with external circuitry, and route is avoided to be exposed to wind-guiding runner 132
It is interior, influence air output.
Further, in one embodiment, far from centrifugation blade 11 direction on the inner casing 134 outer diameter gradually
Reduce, and the slope of 134 outer wall of the inner casing is gradually reduced.So that the outer wall of the inner casing 134, which is formed, is similar to back-off
The shape of bowl, avoids the air-flow in wind-guiding runner 132 from spinning in the surface aggregation of inner casing 134, further increases air output.
Further, in one embodiment, the conducting element 133 can be straight panel or arc panel, as long as described lead
Part 133 is flowed along the longitudinally disposed of wind-guiding runner 132, spiralling air-flow can be guided to flowing up.
Moreover, further, in one embodiment, as shown in Figures 1 to 4, when the conducting element 133 is arc panel
When, the air helically risen is transported out through centrifugation blade 11 and is stopped by the concave surface of the arc panel, and along wind-guiding runner 132
Longitudinal flow.It can be flowed along the concave surface of conducting element 133 when just having contacted conducting element 133 by the air that conducting element 133 is oriented to, so
It is flowed up under the blocking of conducting element 133 afterwards, is further reduced energy loss of the air when contacting with conducting element 133.
Further, in one embodiment, as shown in Figures 1 to 8, the shell 131 is cylindrical housings, the circle
The radius of cylindrical shell is R, and when the conducting element 133 is arc panel, the arc radius of the arc panel isIt is protecting
When hindering guiding role of the conducting element 133 to air, but also whole air quantity is larger.And preferably, the arc of the arc panel
Radius is
