It is connected.Wherein inside air duct 16 is internally provided with the wind wheel of blower 1, and wind wheel in interior 16 internal rotating of crosswind road and can generate stream
Dynamic air-flow, and air-flow is made to export blower 1 from outside air duct 15.In the present embodiment, inside air duct 16 is roughly annular, outside
Crosswind road 15 is tangential on inside air duct 16 and draws, and what the internal perisporium in outside air duct 15 surrounded is generally shaped like cylinder, wherein by
The direction of 15 inside of outside air duct towards the opening extension of outside air duct 15 is first direction, and first direction is parallel to outer crosswind
The axis in road 15.
Spiral case lid volute tongue 4 is convexly equipped on spiral case lid 2, that is, spiral case lid volute tongue 4 protrudes the inner circumferential for being set to outside air duct 15
Wall, in order to carry out guide functions to air-flow by spiral case lid volute tongue 4, and spiral case lid volute tongue 4 is set to outside air duct 15
Inside, as side of the outside air duct 15 close to inside air duct 16.Spiral case seat volute tongue 5 is convexly equipped on spiral case seat 3, that is, spiral case seat
Volute tongue 5 protrudes the internal perisporium for being set to outside air duct 15, in order to carry out guide functions to air-flow by spiral case lid volute tongue 4, and
And spiral case seat volute tongue 5 is set to the inside in outside air duct 15.In addition, when spiral case lid 2 is connected with spiral case seat 3, spiral case lid snail
Tongue 4 and spiral case seat volute tongue 5 connect, i.e., spiral case lid volute tongue 4 is mutually spliced with spiral case seat volute tongue 5, so that can be by carrying out to air-flow
Guiding, and realize the purpose for improving snail wind phenomenon and noise reduction.
Fig. 2, Fig. 3, Fig. 4 and Fig. 5 are please referred to, in the present embodiment, spiral case lid volute tongue 4 includes 6 He of the first volute tongue section
Second volute tongue section 7, the first volute tongue section 6 is set to the inside in outside air duct 15, and the first volute tongue section 6 is from the interior of outside air duct 15
Side extends in a first direction, that is, the first volute tongue section 6 extends from the axis in air duct 15 on the outside of the interior lateral edge in outside air duct 15.Second
Axis of the volute tongue section 7 from the first volute tongue section 6 along the end of first direction along outside air duct 15 extends, i.e., the second volute tongue section 7 is set
It is placed in first one end of volute tongue section 6 far from inside air duct 16.And in the present embodiment, the first volute tongue section 6 is higher than the second volute tongue
Section 7, when the axis in crosswind road 15 is as reference in addition, the distance between the first volute tongue section 6 and 15 axis of outside air duct are less than the
The distance between two volute tongue sections 7 and 15 axis of outside air duct can make spiral case lid volute tongue 4 form two sections of volute tongues.When spiral case lid 2
When being connected with each other with spiral case seat 3, spiral case seat volute tongue 5 is spliced with 6 phase of the first volute tongue section.Wherein, by the way that spiral case lid volute tongue 4 to be arranged
It just can guarantee the phenomenon that can smoothly be guided to air-flow by two sections of volute tongues, 1 snail wind of blower can be improved for two sections of volute tongues
Air-flow it is smooth, and then realize the purpose of noise reduction simultaneously.
In the present embodiment, the development length of the first volute tongue section 6 is equal to the development length of spiral case seat volute tongue 5.Wherein, first
The development length of volute tongue section 6 refers to, the length that the first volute tongue section 6 extends in a first direction, in other words as the first volute tongue section 6
The length that axis along outside air duct 15 extends, i.e. the first volute tongue section 6 on the outside the axis in air duct 15 projection on straight line
Length；The development length of spiral case seat volute tongue 5 refers to, the length that spiral case seat volute tongue 5 extends in a first direction, in other words as snail
The length that axis of the shell block volute tongue 5 along outside air duct 15 extends, i.e., straight line where the axis in the air duct 15 on the outside of spiral case seat volute tongue 5
On projected length.
Specifically, the development length of the first volute tongue section 6 is 8mm~20mm.Similarly, the development length of spiral case seat volute tongue 5 is
8mm~20mm.Wherein, the development length of the first volute tongue section 6 can be 10mm, 12mm or 15mm etc.；Similarly, spiral case seat volute tongue
5 development length can be 10mm, 12mm or 15mm etc..
By setting equal for the development length of the development length of the first volute tongue section 6 and spiral case seat volute tongue 5, when the first snail
It when tongue section 6 is mutually spliced with spiral case seat volute tongue 5, is avoided that gap occur, and guarantees the first volute tongue section 6 and 5 phase of spiral case seat volute tongue
Planarization after splicing, and then guarantee to play smoothly guide functions to air-flow.

From for 10mm~25mm.In other words, the length and the second volute tongue section 7 for being also considered as the second volute tongue section 7 are along the end of first direction
The sum of length that portion to outside air duct 15 is open is 10mm~25mm.Wherein, the first volute tongue section 6 is along the end of first direction to outer
The distance of the opening in crosswind road 15 can be 10mm, 15mm, 18mm or 20mm etc..
The distance of the opening in end to the outside air duct 15 in 5 outside of spiral case seat volute tongue is 10mm~25mm, i.e. spiral case seat snail
Tongue 5 is 10mm~25mm along the distance of the opening of the end of first direction to outside air duct 15.In the present embodiment, spiral case seat snail
The distance of the opening in the end of tongue 5 to outside air duct 15 can be 10mm, 15mm, 18mm or 20mm etc..
Second volute tongue section 7 includes the second extended segment 10 and the second linkage section 11.Second extended segment 10 is from the first volute tongue section 6
The end of first linkage section 9 is straight to extend, i.e. the axis in the parallel outside air duct 15 of the extending direction of the second extended segment 10.The
The end of two linkage sections 11 from the second extended segment 10 is obliquely extended, and is connected with the internal perisporium in outside air duct 15.Due to
Two linkage sections 11 are obliquely extended so that the distance between the second linkage section 11 and 15 axis of outside air duct extend along direction by
It is cumulative big.Also, it is obliquely extended by second linkage section 11, enables the internal perisporium of the second volute tongue section 7 and outside air duct 15
Between be smoothly connected, be conducive to the second volute tongue section 7 for air-flow stablize be oriented to.
It should be noted that wherein, since the second linkage section 11 is substantially in plate shaped, and the internal perisporium in outside air duct 15
