Around 410, it is 38 that the quantity of 416 upper end air blade 412 of support ring is identical as the quantity of lower end air blade 412, cyclic annular muscle
413 settings are in 412 upper end of upper layer air blade, and cyclic annular muscle 413 and axle sleeve 410 are coaxial；It is set alternatively up and down by air blade 412
It is placed in the structure of the periphery of 416 upper and lower end face of support ring, so that the position of air outlet is made to be staggered, different air outlet outflows
Air interact and reduce, turbulent flow phenomenon is reduced, and reduces the vibration that wind wheel generates during the work time, reduces noise point
412 quantity of air blade of shellfish, upper and lower ends is identical, and circumference array is arranged around axle sleeve 410, keeps the stress of upper and lower ends equal
It is even, it is few to the percussion of the structure of wind wheel 41, improve the service life of wind wheel 41.The setting of cyclic annular muscle 413, secures
The upper end of layer air blade 412, and the center of gravity of wind wheel is moved up, cooperate the axle sleeve 410 and support base 411 of coaxial arrangement, makes wind
Wheel 41 is more firm during the work time, and improves the air-tightness of top air outlet.Axle sleeve 410, support base 411, fan blade
Piece 412, cyclic annular muscle 413 are made up of integrated injection molding, so that 41 lighter in weight of wind wheel, sound construction.As an improvement, fan blade
Piece 412 is arc-shaped structure, and the interior thickness of air blade 412 is greater than two-end thickness, and wind effect is good and resistance to deformation is strong
Degree is high, meets the path of air flowing, keeps air flowing more smoothly.And the inner hole of axle sleeve 410 can be D-shaped hole, cooperation electricity
The output shaft of machine 40 is installed, and avoids skidding.The specific work process of blowing device 4 are as follows: by the D-shaped inner hole of axle sleeve 410,
Match to merge with the output shaft of motor 40 and be installed on motor 40, start motor 40, wind wheel 41 rotates, the upper and lower ends in wind wheel 41
Air be discharged by air blade 412 from the side of wind wheel 41, lower air adds in wind wheel 41, and 41 both under air of wind wheel is logical
The interstitial flow to upper end between adjutage 415 is crossed, is so repeated, realizes exhausting function.In addition, air interchanger 5 and blowing dress
Set 4 structure it is identical, the structure of details are not described herein air interchanger 5 can refer to the specific structure of blowing device 4.
As shown in Fig. 2 to Fig. 8, the coaming plate 10 is equipped with several location holes 13 for being used for assembling shell 3, location hole 13
Length direction along coaming plate 10 is evenly distributed, and the lateral edge of the shell 3 is equipped with the installation for being adapted to corresponding location hole 13
Hole 30, the location hole 13 and mounting hole 30 distinguish the first spiral case 11 and the second spiral case 12
Installation is bonded with the sealing bottom surface of shell 3.Specifically, the connector is screw, the first spiral case 11 and the second spiral case 12 divide
Installation is not bonded with the sealing bottom surface of shell 3 and refers to that the upper surface 15 of the first spiral case 11 and the second spiral case 12 respectively corresponds and shell
Body 3 is close to towards 32 flush seal of the bottom surface of panel 1, to achieve the effect that sealing, sealing mentioned here is not absolute
Sealing, in other words, be exactly bottom surface 32 palette of the upper surface 15 with shell 3 of the first spiral case 11, the second spiral case 12 it is upper
32 palette of bottom of end face 15 and shell 3, the case where preventing blowing device 4 and air interchanger 5 from leaking out in exhausting.
As an improvement, the shell 3 is equipped with upper surface 15 and the second snail for sealing the first spiral case 1 towards the bottom surface of panel 1 32
The PE heat-preservation cotton 33 of the upper surface 15 of shell 12, specifically, after being fixed panel 1 and shell 3 by connector, first snail
The corresponding PE heat-preservation cotton 33 compressed on bottom surface 32 in the upper surface 15 of shell 11；Similarly, the upper surface 15 of second spiral case 12 is corresponding
The PE heat-preservation cotton 33 on bottom surface 32 is compressed, such purpose of design is to be adapted to first spiral case 11 and the second spiral case 12 to compress
In PE heat-preservation cotton 33,33 one side of PE heat-preservation cotton can prevent the temperature in heat gas of heating device 6 from dissipating by shell 3
It loses, avoids 3 temperature of shell excessively high and the accident scalded, the first spiral case 11 and the second spiral case 12 on the other hand can be enhanced
Leakproofness further prevents leaking out.
As shown in Figure 1, Figure 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 7 show the present embodiment two, and basic structure is similar to embodiment one,
Except that respectively corresponding for being embedded in the first spiral case 11 and in the shell 3 towards offering on the bottom surface of panel 1 32
The seal groove 34 of two spiral cases 12 replaces PE heat-preservation cotton 33, and preferably the depth of seal groove 34 is 1 millimeter.The seal groove 34
Shape matches the projection of shape of the first spiral case 11 and the second spiral case 12, i.e. 15 He of upper surface of the first spiral case 11 of the corresponding installation of adaptation
The groove of the upper surface 15 of second spiral case 12, it is described to make the first spiral case 11 and the second spiral case 12 be easy to install with seal groove 34
The width H of seal groove 34 is greater than the thickness h of the first spiral case 11 and the second spiral case 12, for the present embodiment two, the width H
It is 1mm with thickness h difference.After first spiral case 11 and the second spiral case 12 are assembled with the seal groove 34 on panel 3, so that first
The upper surface 15 of spiral case 11, the second spiral case 12 upper surface 15 respectively correspond and accomplish zero clearance between seal groove 34, guarantee not
It can leak out.
In conclusion the utility model is integrated with panel 1 by the first spiral case 11, the second spiral case 12, after disassembly panel 1 just
It is repaired or replaced in blowing device 4 or air interchanger 5, improves the efficiency of dismounting.In addition, and the first spiral case 11,
The upper surfaces 15 of two spiral cases 12 and shell 3 are tightly connected by PE heat-preservation cotton 33 or seal groove 34, ensure that the first spiral case 11, the
Two spiral cases 12 can be fully sealed agent with shell 3 respectively and be bonded assembly, between the first spiral case 11, the second spiral case 12 and shell 3 not
There are any gaps, prevent the case where leaking out.
