In some embodiments of the utility model, the first sub- spiral case 1 includes 11 He of the first spiral case half-shell of circumferentially extending
Be connected to the outlet section 12 of the side in the circumferential direction of the first spiral case half-shell 11,12 inside of outlet section with inside the first spiral case half-shell 11
Connection, and one end far from the first spiral case half-shell 11 of outlet section 12 limits air outlet 100b, the second sub- spiral case 2 is circumferentially
Extend 100 half-shell of the second spiral case, 100 half-shell of the second spiral case be connected with the first spiral case half-shell 11 and side limit jointly to
A few air inlet 100a, wherein the first joint surface and the second joint surface are located at the connection of the first sub- spiral case 1 and the second sub- spiral case 2
At the position of the neighbouring outlet section 12 at place.
For example, outlet section 12 can be generally formed into tubular structure, axial one end of outlet section 12 as shown in Fig. 1-Figure 10
Be connected with the circumferential side of the first spiral case half-shell 11 so that the inside of outlet section 12 be connected to inside the first spiral case half-shell 11, outlet section
The 12 axial other end can limit the air outlet 100b of spiral case 100, that is to say, that the first sub- spiral case 1 limits air outlet
100b, so that production material tissue is facilitated, when spiral case 100 is applied to centrifugal blower 200, the wind wheel of centrifugal blower 200
101, the first sub- spiral case 1 and the second sub- spiral case 2 can be supplied together, be transported, and improve the production efficiency of centrifugal blower 200；
First spiral case half-shell 11 can be fastened with 100 half-shell of the second spiral case to be connected, and the first spiral case half-shell 11 and 100 half-shell of the second spiral case can
Air inlet 100a is limited jointly at least side in 11 axial direction of the first spiral case half-shell, so that air can pass through air inlet
100a is flowed into spiral case 100 and is flowed in duct space, may finally be flowed out by air outlet 100b.Wherein, the first engagement
Face and the second joint surface are located at the position of the neighbouring outlet section 12 of the junction of the first sub- spiral case 1 and the second sub- spiral case 2, and first
Joint surface and the second joint surface can be all formed as along the axially extending of spiral case 100, so that first connecting portion 10a and first extends
Portion 10b can be both formed on outlet section 12, and first connecting portion 10a and the first extension 10b can be along spiral case 100
Axially extending, second connecting portion 20a and the second extension 20b can also be along the axially extending of spiral case 100, and then are guaranteeing snail
Under the premise of 100 air quantity of shell, facilitate first connecting portion 10a, the first extension 10b, second connecting portion 20a and the second extension
The setting of 20b simplifies the structure of spiral case 100.
Optionally, the inner wall of the inner wall protrusion first connecting portion 10a of second connecting portion 20a.For example, in Fig. 8-Figure 10
Example in, the inner wall of second connecting portion 20a can be positioned at the upstream of the inner wall of first connecting portion 10a, that is to say, that gas
It flows when being flowed in duct space, air-flow can first flow through the inner wall of second connecting portion 20a and pass through first connecting portion 10a's
Inner wall；On the thickness direction of spiral case 100, the inner wall of the inner wall of second connecting portion 20a protrusion first connecting portion 10a,
So that the inner wall of second connecting portion 20a is located at the inside of first connecting portion 10a inner wall, air-flow is flowing through the first sub- spiral case 1
And second sub- spiral case 2 junction when, avoid and hit between air-flow and first connecting portion 10a, equally further decrease
Air-flow flows the abnormal sound of generation in air duct, simultaneously because the inner wall of second connecting portion 20a and first connecting portion 10a's is interior
Wall surface and unjustified setting reduce the cooperation required precision of first connecting portion 10a and second connecting portion 20a, facilitate first
The quick-fit of sub- spiral case 1 and the second sub- spiral case 2.
Further, as shown in figure 8, on the wall thickness direction of spiral case 100, the inner wall of first connecting portion 10a and second
The distance between inner wall of interconnecting piece 20a is x, and x meets: 0mm < x≤b/2, b=min { b1, b2 }, wherein b1 is the first son
The wall thickness of spiral case 1, b2 are the wall thickness of the second sub- spiral case 2, that is to say, that on the wall thickness direction of spiral case 100, first connecting portion
The distance between the inner wall of 10a and the inner wall of second connecting portion 20a x are no more than the wall thickness and the second son of the first sub- spiral case 1
The half of the smaller value of the wall thickness of spiral case 2, wherein the first sub- spiral case 1 and the second sub- spiral case 2 can be all formed as equal wall thickness knot
Structure.As a result, by the distance between the inner wall of the inner wall of setting first connecting portion 10a and second connecting portion 20a x, x is avoided
The excessive circulation area for leading to duct space of value mutates between first connecting portion 10a and second connecting portion 20a and is made
It brings about the desired sensation raw abnormal sound of miscarrying, to ensure that the experience effect of user.
