And interface 11 is arranged on longitudinal front end of main body 10.Interface 11 is for being connected with airduct 2.Specifically, interface 11 is connected with the connector 25 of airduct 2.Interface 11 in main body 10 has and only has one, no matter is therefore under blowing mould formula or suction mode, and airduct 2 is all connected to this interface 11.Connector 25 substantially match that of the shape of interface 11 and airduct 2.In the present embodiment, interface 11 is arranged towards longitudinal front end, and the first opening 12 is arranged towards longitudinally aft end, therefore interface 11 with the opening of the first opening 12 towards contrary.And interface 11 and the first opening 12 are positioned at the opposite sides of air flow-producing device.For main body 10, when suction and blowing device 1 is under blowing mould formula, as shown in Figure 4, air enters main body from the first opening 12, then moves generally along rectilinear direction, and leaves main body 10 from interface 11, and enters airduct 2 accordingly.And under suction mode, air enters main body 10 from interface 11, then linearly leave main body 10 from the first opening 12.Therefore, under blowing mould formula and suction mode, the air-flow that air flow-producing device produces moving direction between interface 11 with the first opening 12 is contrary.Moreover, it is noted that in the present embodiment, the fan axis 39 of fan 3 extends through interface 11.For the fan 3 of air flow-producing device and motor 4, motor 4 is between fan 3 and the first opening 12 so that the distance of motor the 4 to the first opening 12 is less than the distance of fan the 3 to the first opening 12.In the present embodiment, fan 3, motor 4 and the first opening 12 linearly spread configuration successively.Interface 11 and the first opening 12 lay respectively at the both sides of fan 3 along the bearing of trend of fan axis 39.In other words, interface 11 and the first opening 12 are positioned at the opposite sides of air flow-producing device.Interface 11 overlaps at least partly with the projection in the plane being perpendicular to fan axis 39 of first opening 12.Therefore, interface 11, fan 3, motor 4 and the first opening 12 linearly spread configuration successively.

After airduct 2 is connected to main body 10, under blowing mould formula, air flow-producing device produces the air-flow moved along a direction, air enters shell 14 from the first opening 12 of main body 10, then mobile until forming the air-flow that the mouth of pipe 21 from airduct 2 blows out in main body 10, in the moving direction of air-flow such as Fig. 4 shown in single lined arrows.And under suction mode, airduct 2 still connects main body 10, and connect the position not change of main body 10.Air flow-producing device produces the air-flow moved in another direction, and the moving direction of air-flow is different from the direction moved in blowing mould formula downstream in such a mode, and air enters airduct 2 from the mouth of pipe 21.Air-flow is mobile in main body 10 after sucking, and ultimately forms the air-flow discharged from the first opening 12, in Fig. 5 shown in single lined arrows.Certainly additionally it is emphasized that under suction mode, owing to the mouth of pipe 21 is directed at ground, the foreign body such as leaves, branch, dust together can be entered in main body 10 by the mouth of pipe 21 with air-flow.And under blowing mould formula, the first opening 12 is away from ground, therefore only air can enter main body 10.Therefore, as shown in Figure 6, inside suction and blowing device 1, forming the gas channel 55 of supplied gas flowing between the first opening 12 and the mouth of pipe 21, in other words, shell 14 and airduct 2 are collectively forming the gas channel 55 moved for air-flow.This gas channel 55 is the path that gas moves through in suction and blowing device 1.In normal circumstances, there is due to suction and blowing device 1 different mode of operation blowing mould formulas and suction mode, for the consideration each showing performance, be different at different mode of operation downstream passages.And in this utility model, gas channel 55 is the passage that air-flow is used in conjunction with under blowing mould formula and suction mode.It is to say, under blowing mould formula and suction mode, air-flow all moves in this same gas channel.Only in both modes, the direction that air-flow moves differs.Optimum, the direction that both of which downstream moves is contrary.Specifically, under blowing mould formula, air-flow moves from the first opening 12 to the mouth of pipe 21.And under suction mode, air-flow moves from the mouth of pipe 21 to the first opening 12.Moreover, it is noted that gas channel 55 extends longitudinally on the whole, certain gas channel 55 can also the bending of generating section or bending.In the present embodiment, fan 3 and motor 4 are respectively positioned in gas channel 55.When being in blowing mould formula, fan 3 is subject to the driving of motor 4 and rotates, and fan 3 is rotated in a clockwise direction around fan axis 39, and when being switched to suction mode, fan 3 is subject to the driving of motor 4 and rotates, and fan 3 rotates in the counterclockwise direction around fan axis 39.And in the embodiment shown in Figure 20, fan 3 is still located in gas channel 55, motor 4 is not in gas channel 55.

As shown in Figure 7 and Figure 8, suction and blowing device 1 also includes duct 5.The effect of duct 5 guides the air-flow that fan 3 produces to move to airduct 2, so that the direction that air-flow moves is more consistent, improves the effect of whole air-flow.In the present embodiment, duct 5 is similarly positioned in gas channel 55, and between interface 11 and fan 3.Duct 5 is arranged near the interface 11 of main body 10, and duct 5 compared to fan 3 closer to longitudinal front end, duct 5 is positioned at the fan 3 side away from the first opening 12 in other words.When fan 3 produces the air-flow that moves to interface 11, air-flow can first pass through duct 5 and arrive interface 11 again.In other words, air-flow can first pass through the water conservancy diversion of duct 5 before reaching interface 11.Duct 5 includes and is positioned at baffle 51 within shell 14, the fixing stator blade 52 connecting baffle 51 and for receiving the kuppe 53 of baffle 51 and stator blade 52.Kuppe 53 is positioned at the inside of shell 14, and forms space between kuppe 53 and shell 14.In the present embodiment, kuppe 53 is the cylindrical shell of inner hollow, cylindrical shell inner containment baffle 51 and stator blade 52.The air-flow that fan 3 produces passes through from the inside of kuppe 53.Kuppe 53 is preferably additionally provided with the retaining element 54 of projection.Retaining element 54 arranges the outside being positioned at kuppe 53, and can fixing with the inner side of shell 14 connect, thus playing the effect of fixing kuppe 53 position.In the present embodiment, retaining element 54 can be the rib on prominent surface, and setting in the form of a ring.In another embodiment as shown in figure 17, being additionally provided with damper mechanism 56 between kuppe 53 and shell 14, damper mechanism 56 is for reducing the vibration passing to shell 14 from kuppe 53.Being provided with locating slot 57 on kuppe 53, namely damper mechanism 56 is accommodated in this locating slot 57.And the positioning step 58 coordinating locating slot 57 it is provided with in the inwall corresponding position of shell 14.In the present embodiment, damper mechanism 56 is the annular elastic ring around kuppe 53.Certainly, damper mechanism 56 can also be block elastomer block.Additionally arrange it is noted that damper mechanism 56 is preferably located in longitudinal front end of kuppe 53.Kuppe 53 also has the auxiliary section 59 being arranged on longitudinally aft end.Auxiliary section 59 extends longitudinally equally.Auxiliary section 59 has the pyramidal structure of radius gradual change, the similar horn mouth towards open rearward end of pyramidal structure, and its effect is for the motor cover 44 of part laminating parcel motor 4.Motor cover 44 can partly coordinate fixing with auxiliary section 59.Kuppe 53 extends longitudinally, and its longitudinal two ends are not all closed.Certainly in other embodiments, shell 14 can also as kuppe 53.

Baffle 51 is arranged in kuppe 53.Baffle 51 entirety extends approximately along axis 41 direction, and tapered structure, and its one end is towards interface 11；And other end interface 11 dorsad, this end of interface 11 has opening dorsad.The bearing of trend of baffle 51 is consistent with the bearing of trend of kuppe 53.Baffle 51 has the inside of hollow, and other elements can enter into the inside of baffle 51 by this opening.The air-flow that fan 3 produces passes through from the outside of baffle 51.Therefore, baffle 51 coordinates the air-flow produced so that fan 3 to pass through between baffle 51 and kuppe 53 with kuppe 53.

It is provided externally with stator blade 52 at baffle 51.Stator blade 52 preferably circumference is evenly distributed on baffle 51.Stator blade 52 is fixing with baffle 51 to be connected.Preferably, generally ramped certain angle is arranged the plane that stator blade 52 is formed with the direction of axis 41.Angle of inclination could be arranged between 8 degree to 15 degree.The quantity of stator blade 52 substantially 7.Duct 5 is arranged in gas channel 55.Space between kuppe 53 and baffle 51 is for air-flow traverse.And stator blade 52 is arranged between baffle 51 and kuppe 53, it is located exactly among gas channel 55, it is possible to the air-flow passed through is guided.Owing to, under blowing mould formula, duct 5 is positioned at the downstream area of fan 3, when passing through duct 5 from the air-flow of fan 3 blowout, produce rectified action, such that it is able to the rotation direction of adjustment member air-flow, reduce the generation of eddy current, make overall airflow direction more neat, promote airflow effects and the efficiency of air-flow.It should be noted that the blade 32 of stator blade 52 and fan 3 is all around axis circumferentially disposed.In order to avoid both interfering in the circumferential, it is ensured that its in the arbitrary phase of circumference will not vaned more coincidence and produce similar resonance synergistic effect so that the quantity of stator blade 52 and blade 32 arranges prime number each other.Such as, stator blade 52 could be arranged to 6, and the quantity of blade 32 should be 11 mutually.The quantity of such as stator blade 52 7 again, and the quantity of blade 32 corresponds to 12.So when fan 3 carries out rotation work, arbitrarily carving for the moment, blade 32 and stator blade 52 quantity of overlap in phase place is at most one.It is interior and one-body molded with main body 10 fixing that duct 5 may be located at main body 10, and certain duct 5 can also connect as an independent element is fixing with main body 10.And in a further embodiment, duct 5 can also be arranged in airduct 2.

As shown in Figure 4 and Figure 5, suction and blowing device 1 has at least two mode of operation: blowing mould formula and suction mode.When suction and blowing device 1 is in blowing mould formula, fan 3 operationally rotates in the first direction so that the air-flow of generation blows out from the mouth of pipe 21 of airduct 2.When suction and blowing device 1 is in suction mode, fan 3 operationally rotates in a second direction so that the air-flow of generation sucks from the mouth of pipe 21 of airduct 2.It should be noted that and no matter be in blowing mould formula or suction mode, airduct 2 is all connected with the interface 11 of main body 10.So when suction and blowing device 1 is switched to suction mode from blowing mould formula, or from suction mode be switched to blowing mould formula time, user is without to the position of airduct 2 and fixing carry out extra operation or movement.Have only to the direction of rotation of fan 3 is controlled.When being switched to blowing mould formula, control fan 3 and rotate in the first direction.When being switched to suction mode, control fan 3 and rotate in a second direction.Further, under blowing mould formula, air enters from the first opening 12 and blows out from the mouth of pipe 21.And under suction mode, air sucks from the mouth of pipe 21 and discharges from the first opening 12.No matter enter is blowing mould formula or suction mode, and the path that air passes through all is between the first opening 12 and the mouth of pipe 21, and the path being moved through is identical.Simply different with the direction that air under suction mode moves under blowing mould formula.Therefore under blowing mould formula or suction mode, suction and blowing device 1 all shares this gas channel 55.Thus simplify the structure of the gas channel of suction and blowing device 1 further, it is not necessary to need additionally to arrange the second gas channel.

Further, since suction and blowing device 1 has the mode of operation that at least two is different, it is therefore necessary to consider how easy to operate switching working mode.Therefore suction and blowing device 1 has pressure-vaccum mode conversion switch, and user operation pressure-vaccum mode conversion switch can carry out pattern switching, for instance is switched to the second mode of operation from the first mode of operation, or is switched to the first mode of operation from the second mode of operation.In this utility model, airduct 2 need not move when switch mode or change position, and therefore pressure-vaccum mode conversion switch can be control switch 91.When operation-control switch 91 switches to the position making fan 3 rotate in the first direction, namely suction and blowing device 1 is in blowing mould formula.When operation-control switch 91 switches to the position making fan 3 rotate in a second direction, namely suction and blowing device 1 is in suction mode.User operation extremely convenient when some advantages that arise therefrom is switching working mode, and airduct 2 or mobile airduct 2 need not be changed.When suction and blowing device 1 need not use, airduct 2 can disassemble with main body 10, it is simple to storage.When suction and blowing device 1 needs to use, no matter it is blowing mould formula or suction mode, it is only necessary to airduct 2 is installed in main body 10, then operation-control switch 91 so that motor 4 starts and rotates along corresponding direction.Specifically, when suction and blowing device 1 is in blowing mould formula, operation-control switch 91 moves to the first operating position, and when suction and blowing device 1 is in suction mode, operation-control switch 91 moves to the second operating position.Even if needing to carry out pattern switching, airduct 2 is without dismounting frequently.The fan 3 being additionally, since suction and blowing device 1 contains aerofoil fan, and owing to aerofoil fan can produce higher wind speed, compared to traditional centrifugal fan, under the premise not increasing size, aspect of blowing efficiency is greatly improved.Owing to motor 4 connects fan 3, when motor 4 is rotated in a clockwise direction, motor 4 will drive fan 3 to be rotated in a clockwise direction；And when motor 4 rotates in the counterclockwise direction, motor 4 will drive fan 3 to rotate in the counterclockwise direction.Therefore in the present embodiment, control switch 91 forms to control motor 4 direction of rotation and indirectly realize the control to fan 3.As shown in Figure 29 to Figure 31, motor 4 includes stator 40 and can the rotor 49 that rotates of relative stator 40.Stator 40 and rotor 49 are wound around coil respectively and access circuit, utilize the electric current that the principle of electromagnetic induction produces after circuit turn-on can realize stator 40 and rotor 49 rotates against.And control switch 91 namely for the break-make of control circuit.Control switch 91 and there is multiple gear, there is multiple operating position in other words.Can operatively move between each gear or operating position.In embodiment as shown in figure 29, control switch 91 and there is pin 102 and pin 105, when controlling switch 91 and operatively being moved to the first operating position, pin 104 and guiding 105 conducting while pin 102 and pin 103 conducting, the now circuit according to conducting, the sense of current of stator 40 place circuit and the sense of current of rotor 49 place circuit are identical, under the effect of electromagnetic induction principle, rotor 49 relative stator 40 is rotated in a clockwise direction, then motor 4 general performance is for being rotated clockwise, corresponding fan 3 is also rotated clockwise accordingly, now suction and blowing device 1 is in blowing mould formula.When needing the pattern of switching suction and blowing device 1, have only to operation-control switch 91 move to the second operating position, as shown in figure 30, pin 2 and pin 1 conducting pin 6 and pin 5 simultaneously turn on, now the sense of current of stator 40 place circuit creates change, and the sense of current of rotor 49 place circuit does not change, thus rotor 49 relative stator 40 rotates in the counterclockwise direction, motor 4 and fan 3 rotate all accordingly in the counterclockwise direction, and now suction and blowing device 1 is in suction mode.Certainly, for those skilled in the art it is contemplated that move to when different operating positions, making the electric current through stator 40 constant, and make the sense of current of rotor 49 change controlling switch 91.In a word, when controlling switch 91 and moving to diverse location, make to produce to change through one of them the sense of current of rotor 49 and stator 40.Therefore the method controlling suction and blowing device switching pressure-vaccum pattern is that operation-control switch 91 moves to the second operating position making aerofoil fan rotate in a second direction from the first operating position making aerofoil fan first direction rotate.And in handoff procedure, airduct 2 connects the position of main body 10 and remains unchanged.In a preferred embodiment, control switch 91 and can also have the 3rd operating position being different from first, second operating position.At this operating position, as shown in figure 31, pin 102 and pin 105 are not connected with other pins, therefore the not conducting of the circuit of connecting stator 40 and rotor 49, say, that motor 4 can't rotate, and is in the state of shutdown.Therefore control switch 91 to control motor 4 and switch between three kinds of states, be rotating forward state, stopped status and inverted status respectively.It addition, as shown in Figure 29 to Figure 31, at stator 40 or/and the circuit at rotor 49 place can also arrange the safety switch 84 of linkage release mechanism 8.When safety switch 84 is not triggered, no matter controlling which operating position switch 91 is in, whole circuit is at off state, and motor 4 will not start all the time.Only when safety switch 84 is triggered, control the effect of switch 91 competence exertion control circuits.

It addition, as shown in Fig. 2, Fig. 6 and Fig. 7, suction and blowing device 1 also includes disintegrating mechanism 6.Due to fan 3 or/and motor 4 is respectively positioned in gas channel 55, under suction mode, the object that tree branches and leaves equal-volume is bigger can enter into main body 10 in company with air from the mouth of pipe 21, therefore to fan 3 or/and motor 4 causes damage, can affect the service life of suction and blowing device 1.Therefore the purpose arranging disintegrating mechanism 6 is that the inhalation (inhalatio) that volume is bigger is pulverized, change into small volume, lighter in weight object through passing through fan 3, reduce the damage that the bigger objects at high speed of weight is clashed into fan 3 and caused fan 3.Therefore disintegrating mechanism 6 is arranged on the position between fan 3 and the mouth of pipe 21, in the present embodiment, disintegrating mechanism 6 is arranged on the position in main body 10 near interface 11 so that after thing to be comminuted enters main body 10 from the mouth of pipe 21 under suction mode, first pass through disintegrating mechanism 6 again through fan 3.In the present embodiment, duct 5 is between disintegrating mechanism 6 and fan 3, and fan 3 lays respectively at relative each side of duct 5 with disintegrating mechanism 6, say, that disintegrating mechanism 6 than duct 5 closer to the mouth of pipe 21.Disintegrating mechanism 6, duct 5 and fan 3 linearly spread configuration successively.Duct 5 is positioned at the side away from the first opening 12 of fan 3.Disintegrating mechanism 6 powered can produce crushing effect around a rotation axis rotation.In the present embodiment, disintegrating mechanism 6 can be driven by motor 4 and rotate.Suction and blowing device 1 includes the drive mechanism 7 connecting fan 3 and disintegrating mechanism 6.Drive mechanism 7 makes disintegrating mechanism 6 rotate.In the present embodiment, the rotation axis of disintegrating mechanism 6 overlaps with the pivot center of fan 3 setting.Certainly, the rotation axis of disintegrating mechanism 6 can also be arranged in parallel with the pivot center of fan 3 or become certain acute angle to arrange.Due to the fan 3 in the present embodiment also by the driving of motor 4, therefore motor 4 can simultaneously drive fan 3 and rotates together with disintegrating mechanism 6.In a preferred embodiment, fan 3 and disintegrating mechanism 6 can synchronous axial system.When fan 3 rotates in the first direction, disintegrating mechanism 6 rotates equally in the first direction；When fan 3 rotates in a second direction, disintegrating mechanism 6 rotates accordingly in a second direction.When disintegrating mechanism 6 rotates, disintegrating mechanism 6 high speed rotating forms the cutting planes of substantially vertical axis 41, can't affect air circulation under blowing mould formula；And under suction mode, air and thing to be comminuted all can pass through this cutting planes, wherein; air can be loss-free by this cutting planes, and can be cut into small objects when thing to be comminuted passes through this cutting planes, then again through fan 3; thus reaching the purpose of protection fan 3, and it is beneficial to collection.As shown in Figure 2 and Figure 8, drive mechanism 7 is the power transmission shaft 71 extended longitudinally.Power transmission shaft 71 can rotate around axis 41, certainly rotates axle 71 and power transmission shaft 71 can also be made to be not about axis 41 by some eccentric structures to rotate.One end of power transmission shaft 71 connects fan 3, and the other end then connects disintegrating mechanism 6, so that fan 3 is synchronized with the movement together with disintegrating mechanism 6.Power transmission shaft 71 is connected one end of fan 3 and is connected the connecting hole 33 of fan 3 by the structure such as flat or spline.Owing to motor drive shaft 42 and power transmission shaft 71 lay respectively at the both sides of fan 3, therefore the motor drive shaft 42 of motor 4 connects fan 3 from the side of connecting hole 33, and the power transmission shaft 71 connecting disintegrating mechanism 6 connects fan 3 from the opposite side of connecting hole 33.In the present embodiment, power transmission shaft 71 and motor drive shaft 42 indirect connection, but both linkages are realized by the transmission of fan 3.And after disintegrating mechanism 6 is installed on power transmission shaft 71, this end of power transmission shaft 71 is additionally provided with anti-skid structure 74, the effect of anti-skid structure 74 is to prevent the relative power transmission shaft 71 of disintegrating mechanism 6 from moving axially.In the present embodiment, anti-skid structure 74 is the latch that can be inserted into the jack on power transmission shaft 71.It addition, anti-skid structure 74 also includes pad etc..Owing to motor 4 and disintegrating mechanism 6 are positioned at the opposite sides of duct 5, therefore power transmission shaft 71 meeting is through duct 5, thus motor 4 and disintegrating mechanism 6 are coupled together.In the present embodiment, power transmission shaft 71 passes axially through the inside of baffle 51 hollow of duct 5.As shown in Figure 6, between power transmission shaft 71 and baffle 51, it is additionally provided with the spring bearing 72 for supporting power transmission shaft 71.Power transmission shaft 71 can the rotatable support of relative support bearing 72.The quantity of spring bearing 72 can be one or more.In the present embodiment, the quantity of spring bearing 72 is two, and keeps at a certain distance away setting along the bearing of trend of power transmission shaft 71.And in other embodiments, pass to the transmission of disintegrating mechanism 6 owing to drive mechanism 7 shuts off fan 3, so when fan 3 rotates, disintegrating mechanism 6 can not rotate.In this embodiment, drive mechanism 7 includes and the clutch of motor drive shaft 42 clutch.When clutch is selectively connected with motor drive shaft 42 power, fan 3 rotates together with disintegrating mechanism 6, when clutch selectively disengage with motor drive shaft 42 power be connected time, fan 3 still can rotate, and disintegrating mechanism 6 does not then rotate.

In S2 step, assemble the second assembly.As shown in figure 35, the second assembly mainly includes motor 4 and motor cover 44.S2 step mainly includes S21 and S22 two sub-steps.Owing to motor cover 44 includes two half-shell, in S21 sub-step, motor 4 is fixedly installed in a motor cover half-shell, motor 4 and motor cover half-shell is all correspondingly provided with the rib of positioning action so that motor 4 can be fixedly mounted in motor cover half-shell.In S22 sub-step, other motor cover half-shell is docked with the double-line direction along figure of the motor cover half-shell in S21 sub-step, and is fixed by retaining element such as screw.Second assembly installation, so far S2 step completes.

In S3 step, the first assembly and the second assembly are coupled together.As shown in figure 36, specifically, the fan 3 stretched out in the second assembly in the motor drive shaft 42 of motor cover 44 and the first assembly is connected.The connecting hole 33 of fan 3 is through hole, and its side connects drive mechanism 7, and opposite side then connects with motor shaft 42.Connect concrete mode can be aforementioned mention flat connect or spline connect.After completing connection, the first assembly and the second assembly are substantially longitudinally in tandem.

In S4 step, the first assembly coupled together and the second assembly are installed in shell half-shell.As shown in figure 36, similarly, shell half-shell has the location structure coordinating the first assembly and the second assembly.Location structure can be location rib etc..What control motor 4 motion mode controls switch also by the circuit pin being wired to motor 4 simultaneously.

In S5 step, as shown in figure 36, the double-line direction along figure of the half-shell shell in another shell half-shell and S4 spliced and pass through the fixing connection of retaining element.So just complete the assembling of the main body 10 of suction and blowing device 1.

The suction and blowing device of another embodiment as shown in Figure 17 and Figure 18, the suction and blowing device 1 in this embodiment is essentially identical with the structure of the suction and blowing device shown in Fig. 1.Difference with regard to two embodiments is made an explanation below: in the present embodiment, and the first side 681 and the second side 682 that constitute the cutting blade of disintegrating mechanism 6 are convexly curved, so that whole cutting blade is substantially S-type.Meanwhile, cutting blade also has more small cross sectional areas, in the present embodiment, has shorter spacing between the second side 682 of first side 681 and correspondence, it is preferable that maximum is smaller than 20 millimeters.The auxiliary section 59 of duct 5 has regular texture, the similar funnel structure in whole auxiliary section 59, has the radius bullet 591 being gradually increased and the columnar shirt rim body 592 being positioned at connection bullet 591 end and constitutes.Cooling import 441 ' is also offered at bullet 591.And it is additionally provided with safety guard 121 at the first opening 12 place.Safety guard 121 is positioned at the longitudinally aft end of motor cover 44.The sectional view of the suction and blowing device that Figure 18 show in Figure 17.It will be apparent from this figure that the power transmission shaft 71 connecting disintegrating mechanism 6 and fan 3 is arranged through duct 5.And power transmission shaft 71 is provided with passive spring bearing 72.Spring bearing 72 is additionally provided with damping element 73.The effect of damping element 73 is that the vibration weakening power transmission shaft 71 generation passes to duct 5.Damping element 73 can be socketed in the rubber ring on spring bearing 72 or rubber cap etc..

As shown in figure 18, fan 3 is preferably 5mm～20mm to the spacing between the stator blade 52 of duct 5.Wherein, spacing L is defined as the end of stator blade 52 and rotates to fan 3 and formed and fore-and-aft distance between the plane P at 3 centers in passing through fan.The end of stator blade 52 refers to stator blade 52 one end near fan 3.Stator blade 52 has and necessarily has certain longitudinal length, and the end of stator blade 52 refers to the end gone up along the longitudinal direction near fan 3.Fan 3 rotates and forms the rotational plane P being perpendicular to fan axis 39, and owing to fan axis 39 is longitudinally disposed, therefore the rotational plane P bearing of trend of fan 3 is with longitudinally perpendicular, and the rotational plane P of fan 3 is through the center C of passing through fan 3.It addition, the width of the free end 36 of the blade 32 of definition fan 3 is chord length d, as shown in Figure 3.In the present embodiment, the ratio of spacing L and chord length d is 0.3 to 1.5, it is ensured that the blowing performance of suction and blowing device 1 is higher.If ratio is less than 0.3, illustrate that spacing L is shorter, illustrate that fan 3 is too near to duct 5, it is impossible to give full play to the performance of fan 3, thus being unfavorable for producing higher aspect of blowing efficiency.And if ratio is more than 1.5, illustrate that spacing L is longer, illustrate that fan 3 is too remotely from duct 5, be unfavorable for equally producing high aspect of blowing efficiency.Preferably, when the ratio of spacing L and chord length d is 0.6, aspect of blowing efficiency is the highest.For the chord length d of stator blade 52 for 21mm, when spacing L is 6.3mm, when namely ratio is 0.3, the wind speed that suction and blowing device 1 produces is about 42m/s.And when spacing reaches 12.6mm, when namely ratio is 0.6, the wind speed that suction and blowing device 1 produces is about 45m/s.Accordingly, it can be seen that along with the increase of ratio, wind speed obtains a degree of raising, thus raising efficiency.And when spacing L is 18.9mm, when namely ratio is 0.9, the wind speed that suction and blowing device 1 produces is about 42m/s, it can be seen that when ratio continues to increase, wind speed begins to decline again on the contrary.When spacing L is for being about 31.5mm, when namely ratio is 1.5, the wind speed that suction and blowing device 1 produces is positioned at 36m/s, it can thus be seen that wind speed declines significantly, work efficiency is unsatisfactory.Therefore, most preferred embodiment be ratio about 0.6, when the chord length of the blade 32 of fan 3 is 21mm, spacing L is preferably 12.6mm, and now work efficiency is the highest.

Owing to, under blowing mould formula, duct 5 is positioned at the downstream area of fan 3, when passing through duct 5 from the air-flow of fan 3 blowout, produce rectified action, such that it is able to the rotation direction of adjustment member air-flow, reduce the generation of eddy current, make overall airflow direction more neat, promote airflow effects and the efficiency of air-flow.Specifically, owing to air needs successively to pass through the stator blade 52 of duct 5 and the blade 32 of fan 3, it is circumferentially disposed that the blade 32 of stator blade 52 and fan 3 is all around axis.In order to avoid both interfering in the circumferential, it is ensured that its in the arbitrary phase of circumference will not vaned more coincidence and produce similar resonance synergistic effect so that the quantity of stator blade 52 and blade 32 arranges prime number each other.If stator blade 52 and the quantity of blade 32 exist non-1 or itself approximate number non-, then be at a time likely to multiple phase places with blade 32 identical for stator blade 52, thus producing the flow-disturbing of similar resonance synergistic effect, affects the stability of air-flow.In the present embodiment, the quantity of stator blade 52 is preferably 5～8.If stator blade 52 if to arrange quantity very few, for instance 4,3, then have portion of air directly from space traverse between stator blade 52 between two, without by stator blade 52 water conservancy diversion, causing the generation of local eddy currents, the aspect of blowing efficiency of the overall air-flow of impact.And if stator blade 52 a fairly large number of words are set, for instance 9,10, although water conservancy diversion effect is better, but owing to stator blade 52 is excessively intensive, have impact on air and cross wind area at gas channel 55 so that gas flowing is obstructed, reduces wind speed.In the present embodiment, the quantity of stator blade 52 is preferably 6.And blade 32 quantity of the fan 3 of correspondence is 11, so can ensure that both quantity prime numbers each other.In another embodiment, the quantity of stator blade 52 7, and the quantity of blade 32 corresponds to 12.So when fan 3 carries out rotation work, arbitrarily carving for the moment, blade 32 and stator blade 52 quantity of overlap in phase place is at most one.

It is otherwise noted that in order to isolate cooling duct and gas channel 55 further, it is prevented that air-flow is being ganged up mutually, and motor cover 44 also includes sealing member 443.Sealing member 443 is arranged on transmission interface 45 place of motor cover 44.The reason arranging transmission interface 45 is to make motor drive shaft 42 outwards pass to be in transmission connection with fan 3 by this transmission interface 45.Owing to the radial dimension of transmission interface 46 is naturally larger than the radial dimension of motor drive shaft 42, therefore there is gap between transmission interface 46 and motor drive shaft 42, it is internal that the partial air in gas channel 55 outside motor cover 44 can enter into motor cover 44 by this gap, thus disturbing being independently arranged of gas channel 55 and cooling duct.As it can be seen, be provided with sealing member 443 at transmission interface 46 place, sealing member 443 can be arranged gas channel 55 with cooling duct isolation, it is prevented that the air-flow in these two passages is circulated mutually by this transmission interface 46.In the present embodiment, sealing member 443 is barrel shaped structure.The circumferential side wall of tubular construction is the bucket wall of entity.It is positioned at a two ends for arm bearing of trend and is opening setting.Therefore the sealing member 443 barrel shaped structure in through setting.Motor drive shaft 42 extends through from the inner hollow of sealing member 443.One end of sealing member 443 is installed and connected in transmission interface 46, and the other end is positioned at the inside of motor cover 44.Specifically, this end of sealing member 443 is connected to the supporting construction 46 supporting motor 4.Further, sealing member 443 is connected to the fore-stock 461 of supporting construction 46.Fore-stock 461 is provided with the spring bearing 464 supporting motor drive shaft 42, and spring bearing 464 only holds the gapless traverse of motor drive shaft 42.Therefore, spring bearing 464 can seal this end opening of sealing member 443, internal for motor cover 44 and motor cover 44 external isolation.The gearing of motor drive shaft 42 can't be affected simultaneously.It is so designed that, is arranged in the air-flow of the gas channel 55 outside motor cover 44 due to the bucket wall of sealing member 443 and the barrier effect of spring bearing 464 and cannot be introduced into the inside of motor cover 44.And the air-flow of the cooling duct within motor cover 44 is also due to the bucket wall of sealing member 443 and the barrier effect of spring bearing 464 cannot flow to the outside of motor cover 44.Therefore be can ensure that the independence of gas channel 55 and cooling duct by sealing member 443, it is prevented that it interferes, and promotes work efficiency further.And the structure that sealing member 443 connects transmission interface 45 and supporting construction 46 can be the clamping connecting structure that the shape such as boss, draw-in groove is joined.
