Description
Technical field
The utility model concretely relates to a kind of Novel sound-silencing draught fan impeller.
Background technology
Wind turbine is the source of supply air system, its big air quantity, efficient, low noise, long lifespan are required to wind turbine.At present mostly
The wind turbines such as number domestic air conditioning, air purifier are centrifugal fan, and draught fan impeller has conclusive influence to performance of ventilating.It is past
Higher toward rotating speed of air conditioner fan, this results in the design of draught fan impeller that can not take into account the requirement of air quantity and noise simultaneously, existing
Impeller is directly assembled with motor shaft, and impeller material is plastics, and assembly precision and lifetime stability are all very poor, this is resulted in
Impeller high speed rotation gets up vibration greatly, generates noise.
In addition, blower motor, which works long hours, also will produce a large amount of heat, if dispersed not in time, motor can be caused to damage
It is bad.
Invention content
The purpose of this utility model is to provide a kind of Novel sound-silencing draught fan impeller, and smooth running is with small vibration, and noise is small,
In addition the setting of convection holes improves the dissipating-heat environment of blower motor, extends motor service life.
In order to solve the above technical problems, what the purpose of this utility model was realized in：
A kind of Novel sound-silencing draught fan impeller, including blade, it is characterised in that：The faces Xia Kou of the blade are fixed on motor drum
It puts on, face suitable for reading is fixed together by upper fixed ring, and the thickness of blade successively decreases along middle part to both ends, is in wing-shaped structure, institute
The blade stated is installed using the mode of leaning forward；The centrifugal blower fan blade wheel is equipped with and the matched mounting shaft hole of motor, the axis hole
It is inside fixed with axle sleeve, is installed by axle sleeve and machine shaft cooperation；The motor drum set is by the lower motor drum set of tubular and half
Spherical upper motor drum set composition, lower motor drum set and upper motor drum set side wall are respectively arranged with several convection holes, the motor
The drum set back side is provided with reinforcing rib support.
Preferred embodiment on the basis of said program and as said program：The impeller is molded for integral type.
Preferred embodiment on the basis of said program and as said program：The axle sleeve is copper.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：It uses axle sleeve made of copper, assembly essence
Degree is high, and smooth running is with small vibration, and noise is small, and the in addition setting of convection holes improves the dissipating-heat environment of blower motor, and extending motor makes
Use the service life.

Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is motor drum nested structure schematic diagram.
Fig. 3 is blade construction and distribution schematic diagram.
Specific implementation mode
To keep the purpose, technical scheme and advantage of the application clearer, below in conjunction with the attached drawing in embodiment, to reality
The technical solution applied in example is clearly and completely described, it is clear that described embodiment is only that the application part is implemented
Example, rather than whole embodiments.Based on the embodiment provided, those of ordinary skill in the art are not before making creative work
The every other embodiment obtained is put, shall fall in the protection scope of this application.
In the description of the present application, it is to be understood that the orientation or positional relationship of the instructions such as term "upper", "lower" is base
In orientation or positional relationship shown in the drawings, it is merely for convenience of description the application and simplifies to describe, rather than indicate or imply
Signified device or element must have a particular orientation, with specific azimuth configuration and operation, therefore should not be understood as to this
The limitation of application.
In the description of the present application, term " first ", " second " etc. are used for description purposes only, and should not be understood as instruction or
It implies relative importance or implicitly indicates the quantity of indicated technical characteristic.
The faces Xia Kou of a kind of Novel sound-silencing draught fan impeller, including blade 1, blade 1 are fixed on motor drum set 3, face suitable for reading
It is fixed together by upper fixed ring 5, the thickness of blade 1 successively decreases along middle part to both ends, is in wing-shaped structure, before blade 1 uses
Mode of inclining is installed.
Further, centrifugal blower fan blade wheel be equipped with the matched mounting shaft hole 2 of motor, be fixed with axle sleeve 21 in axis hole 2, lead to
Axle sleeve 21 is crossed to install with machine shaft cooperation.
Further, motor drum set 3 is made of the lower motor drum set 31 and hemispheric upper motor drum set 32 of tubular, lower electricity
Machine drum 31 side walls of set are evenly equipped with the first convection holes 7, and upper motor drum 32 side walls of set are evenly equipped with the second convection holes 6 respectively.
The setting of first convection holes 7 and the second convection holes 6 can obviously improve the dissipating-heat environment of motor, and can mitigate leaf
The weight of wheel saves the use of material.
Further, 3 back sides of motor drum set are provided with the support of reinforcing rib 4.
Preferably, impeller is molded for integral type.
Preferably, axle sleeve 21 is copper.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model
Within the scope of.
