Description
Technical field:
The utility model relates to a kind of wind wheel and its air blowers of application.
Background technique:
Existing wind wheel, if being connected to the dry-air blast between top panel and bottom panel including top panel, bottom panel and installation
Air inlet is arranged among bottom panel, air duct is formed between adjacent two air blade, in the top of air inlet, air blade for blade
Side forms cavity, and air outlet, the joint seat of top panel center setting and motor axis connection, the top surface are formed on the outside of fan blade
If the edge of plate is projecting inward to be had around axially uniformly distributed dry plate auxiliary fan blade, auxiliary fan blade and several air blades are distributed in top panel two
Side, an end face of the air blade and bottom panel are combined together by ultrasonic bonding, due between air blade and bottom panel
It is plane-welding, structure assembling trouble, wind wheel is more using material, and the cost is relatively high.
Summary of the invention:
The purpose of the utility model is to provide a kind of wind wheel and its air blower of application, solves structure in the prior art and assemble
The technical issues of trouble, wind wheel is more using material, and the cost is relatively high.
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, the inner end of the blade is exposed in air inlet
Place, the diameter D1 of the air inlet are greater than or equal to the diameter D2 of rear wind disk.
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 end face of 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 part 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 inner end of the blade is exposed to enter the wind
At mouthful, the diameter D1 of the air inlet is greater than or equal to the diameter D2 of rear wind disk, reduces the material of production wind wheel, cost of manufacture
It is low；
2) 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；
3) end face of the outer end passes through stretching after the boss is axially extended outside the bottom surface of wind disk equipped with boss
Boss can increase enough negative pressure values, moreover it is possible to reduce noise；
4) 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；
5) top surface of the axially extended preceding wind disk in the part 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.
