Description

A kind of blower and air purifier

Technical field

The utility model belongs to air cleaning facility technical field, more particularly to a kind of novel blower and air cleaning Device.

Background technique

Air pollution is serious at present, may cause a variety of diseases, air purifier become people purify air selection it One.Air purifier is mainly used for the purification filtering of room air, drives wind wheel rotation by motor, indoor gas is sucked empty Gas purifier, by the processing of strainer and anion generator, air purifier is discharged in clean air.

The blower of existing air purifier is typically all that wind wheel is mounted in the shaft of motor, then will by nut Wind wheel is fixed.When air purifier work, blower high speed rotation is easy to cause nut loosening, so that the loosening of wind wheel is caused, So that it is uneven when wind wheel rotates, there is the problems such as noise increases, clarifier shakes.If nut loosens completely, may lead The destruction that falls off of wind wheel is caused, machine is unable to run.

And wind wheel is fixed by nut, nut, motor shaft influence air-flow flowing, air-flow by these structures when Hou Huiliu must have some setbacks, and influence efficiency and noise increases.And user can be by seeing the inside wind wheel at air inlet of air duct Nut and motor shaft influence the experience of client.

Utility model content

To solve the above-mentioned problems, the utility model proposes a kind of blower and air purifiers, in the nut of fixed wind wheel Lower section increase a wind wheeling cover, good guiding can be carried out to air-flow, reduce windage and noise, and be capable of fixing nut, Prevent nut loosening.

One of the purpose of this utility model is to provide a kind of blower, including motor and wind wheel, and the wind wheel is solid by nut It is scheduled in the shaft of the motor, further includes wind wheeling cover；The wind wheeling cover is shell structure, and top is opening, and inside is cavity； The diameter of the wind wheel cover outer wall and inner wall is gradually reduced from top to bottom；The prominent of annular is equipped at the center of the cavity bottom It rises；The wind wheeling cover is fixedly mounted on the wind wheel, covers the shaft of the motor, the protrusion of the annular and the nut Contact.

In above-mentioned blower, the section of the shell of the wind wheeling cover is arc.

As the preferred scheme of the utility model, the section of the shell of the wind wheeling cover is taper.

As the preferred scheme of the utility model, the opening of the wind wheeling cover extends upward multiple claws, the wind Wheel is equipped with the plane cooperated with the claw, and the wind wheeling cover is engaged by claw with the wind wheel.

Further, multiple claws are uniformly distributed along the circumference of the wind wheeling cover.Further, the claw Quantity is four.

As the preferred scheme of the utility model, the height of the wind wheeling cover is the 1/2~2/3 of the wind wheel height.

The another object of the utility model is to provide a kind of air purifier, including shell and fixed wind inside the shell Machine, the blower are any above-mentioned blower.

The blower and air purifier of the utility model, the nut of fastening is blocked by wind wheeling cover, avoids nut loosening de- Falling causes wind wheel to operate not normal phenomenon, while can play the role of protection；The shape of wind wheeling cover is arc or taper, to passing through Air-flow have good guiding role, have the function of that noise reduction is shockproof.

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, the present embodiment provides a kind of blowers 100, including motor 1,2 and of wind wheel Wind wheeling cover 3.The shaft 11 of motor extends downwardly out the shell of motor, and wind wheel 2 is mounted on the shaft 11 of motor, later in motor Nut 12 is installed to fasten wind wheel 2 in shaft 11.The rotation of the shaft 11 of motor drives the rotation of wind wheel 2, the rotation band of wind wheel 2 Dynamic air forms air-flow.Wind wheeling cover 3 is fixedly mounted on wind wheel 2, the shaft 11 of motor is covered, so that personnel can't see from outside The shaft 11 and nut 12 of motor.

As shown in Figures 2 and 3, wind wheeling cover 3 is shell structure, and top is opening 31, and inside is cavity 32.Wind wheeling cover 3 Shape is similar to bowl-shape, and up big and down small, the diameter of outer wall and inner wall is gradually reduced from top to bottom.It is set at the center of 32 bottom of cavity There is the protrusion 34 of annular, the diameter of annular protrusion 34 is close with the diameter of nut 12, and wind wheeling cover 3 is mounted on wind wheel 2 When, annular protrusion 34 is contacted with nut 12.The protrusion 34 of annular resists nut 12, can prevent 12 loose or dislocation of nut.

As shown in figure 4, as a preferred option, the section of the shell of wind wheeling cover is arc, it can also be taper, such shape Shape facilitates the guidance to air-flow, can reduce windage, reduces noise.Arrow in Fig. 4 represents the trend of air-flow.

Fig. 5 is the perspective view of blower, and visual angle is to look up, as shown in Figure 4 and Figure 5, it is preferred that the opening of wind wheeling cover is upward Extend multiple claws 33, wind wheel is equipped with the plane cooperated with claw, and wind wheeling cover is engaged by claw 33 with wind wheel.Wind wheeling cover 3 are buckled on wind wheel 2, fit closely with wind wheel 2, and other mounting means also may be selected in wind wheeling cover 3 and wind wheel 2.

Multiple claws 33 are uniformly distributed along the circumference of wind wheeling cover 3, and further, the quantity of claw 33 is four.

As a preferred option, the height of wind wheeling cover 3 is the 1/2~2/3 of 2 height of wind wheel.If wind wheeling cover 3 is excessive, can The flowing of air-flow can be will affect, if wind wheeling cover 3 is too small, reduce wind wheeling cover 3 to the guiding function of air-flow, wind wheeling cover 3 Effect substantially reduces.

As shown in fig. 6, the present embodiment provides a kind of air purifier, including shell 200 and fixed blower inside the shell 100, blower 100 is any above-mentioned blower.The lower section of blower 100 is strainer 300, after air enters clarifier, first passes through filter Net 300 is filtered, and is discharged after blower 100 later.Blower 100 and strainer 300 can be fixed by the bracket in shell 200 It is interior.
