The purpose of this utility model is achieved by following technical proposals.

A kind of wind wheel is connected to several blades between preceding wind disk and rear wind disk including preceding wind disk, rear wind disk and installation, Air inlet is set among the preceding wind disk, forms air duct between adjacent two blade, blade is equipped with arrival end, institute towards air inlet The entrance end side surface for stating blade is oblique line, i.e. arrival end and preceding wind disk out of plumb；The height H2 of wind disk is from rear wind disk after described The edge of center wind disk backward is gradually lower by height, make the height in the air duct by rear wind disk center backward wind disk edge by Gradually change from small to big.

The distance H1 of the top of the blade to the bottom surface of rear wind disk be variation, distance H1 from the center of rear wind disk backward The edge of wind disk is gradually lower by height.

The section of the preceding wind disk is convex structure.

The inner end of the blade is exposed in air inlet, and the diameter D1 of the air inlet is greater than or equal to the straight of rear wind disk Diameter D2.

Several outer blade diameter D3 are less than or equal to the outer diameter D 4 of preceding wind disk, after the outer end radially protruding of the blade Except the edge of wind disk.

The outer end is equipped with boss, after the boss is axially extended outside the bottom surface of wind disk.

The preceding wind disk, rear wind disk, blade and boss are integrated injection moldings.

The top surface of the axially extended preceding wind disk in the top of the arrival end of the blade.

A kind of air blower, including spiral case, cover board, motor, motor shaft and wind wheel, spiral case and cover board install the shape that links together At cavity, wind wheel is mounted on inside cavity, and air outlet is arranged on spiral case, and air inlet is arranged in cover board, and the wind wheel is above-mentioned institute The wind wheel for any one stated.

The utility model compared with prior art, has the effect that

1) if the utility model includes the cured leaf that preceding wind disk, rear wind disk and installation are connected between preceding wind disk and rear wind disk Piece, the preceding wind disk centre are arranged air inlet, form air duct between adjacent two blade, the entrance end side surface of the blade is oblique Line, i.e. arrival end and preceding wind disk out of plumb, it is described after wind disk height H2 be from Hou Feng disk center backward wind disk edge gradually It is lower by height, so that the height in the air duct is gradually changed from small to big by the edge of the center wind disk backward of rear wind disk, determined by Bernoulli Jacob Rule, the wind wheel static pressure of the structure is big, and vortex is small, impact of the air-flow to wind wheel can be effectively reduced, to reduce making an uproar for complete machine Sound and vibration；

2) the distance H1 of the top of the blade to the bottom surface of rear wind disk is variation, and the center of distance H1 from rear wind disk is past The edge of wind disk is gradually lower by height afterwards, and by Bernoulli's theorem, the wind wheel static pressure of the structure is big, and vortex is small, can be effectively reduced Impact of the air-flow to wind wheel, to reduce noise and the vibration of complete machine；

3) section of wind disk is convex structure before, increases the structural strength of wind wheel；

4) inner end of the blade is exposed in air inlet, and the diameter D1 of the air inlet is greater than or equal to rear wind disk Diameter D2 reduces the material of production wind wheel, reduces cost of manufacture；

5) several outer blade diameter D3 are less than or equal to the outer diameter D 4 of preceding wind disk, the outer end radially protruding of the blade Afterwards except the edge of wind disk, increase the air-out area of wind wheel, the vibration of complete machine can be lowered, to reduce the noise of complete machine；

6) outer end passes through the boss of stretching after the boss is axially extended outside the bottom surface of wind disk equipped with boss Enough negative pressure values can be increased, moreover it is possible to reduce noise；

7) the preceding wind disk, rear wind disk, blade and boss are integrated injection moldings, and manufacturing process is simple, and wind wheel is whole Stability is good；

8) top surface of the axially extended preceding wind disk in the top of the arrival end of the blade passes through protrusion when wind wheel operation Partial blade rolls up air-flow in inspiration wind wheel, improves wind wheel operational effect.
