Description
Technical field:
The utility model relates to a kind of blower.
Background technique:
As shown in Figure 1, in existing blower, in order to prevent from wind wheel A1 from beating causing the mechanical friction brought between wind wheel A1 and cover plate A2, between wind wheel A1 and cover plate A2, usually can there is certain gap surplus.But because gas itself has viscosity, air-flow can flow along the outer wall of wind wheel A1.Air-flow can flow to the intake grill A3 region in the middle of cover plate A2 along the gap between wind wheel A1 and cover plate A2, cause gas leakage.Air pressure loss can be brought in gap thus between wind wheel A1 and cover plate A2, reduces the efficiency of blower.
Summary of the invention:
The purpose of this utility model is to provide a kind of blower, effectively reduces the gas leakage between wind wheel and cover plate, improves the aspect of blowing efficiency of blower.
The purpose of this utility model is achieved by following technical proposals.
A kind of blower, comprise motor, spiral case, cover plate and wind wheel, spiral case and cover plate are installed together and form a cavity, wind wheel is positioned at inside cavity, motor is arranged on spiral case and the axle stretch end of motor extend into inside cavity and links together with wind wheel, offers intake grill, the side of spiral case is provided with exhaust outlet in the centre of cover plate, intake grill, exhaust outlet are all communicated with cavity, centered by intake grill, in the interior sidewall surface of cover plate, be provided with multiple annular relief.
The center from cover plate described above is toward the outer ledge of cover plate, and the height of annular relief reduces gradually.
The shape of cross section of annular relief described above is triangular in shape.
The shape of cross section of annular relief described above is trapezoidal.
Described above is provided with ring baffle on the outer ledge of cover plate interior sidewall surface, and the bottom of wind wheel extend in the middle of ring baffle.
The top of ring baffle described above is provided with rounding.
The utility model compared with prior art, has following effect:
1) centered by intake grill, in the interior sidewall surface of cover plate, be provided with multiple annular relief, effectively reduce the gas leakage between wind wheel and cover plate, improve the aspect of blowing efficiency of blower;
2) from the center of cover plate toward the outer ledge of cover plate, the height of annular relief reduces gradually, and the closer to the outer rim of wind wheel, beating of wind wheel is larger, beat for preventing wind wheel the mechanical friction caused between wind wheel and cover plate, the annular relief height the closer to wind wheel outer rim is lower;
3) on the outer ledge of cover plate interior sidewall surface, ring baffle is provided with, the bottom of wind wheel extend in the middle of ring baffle, effectively prevent air-flow from entering gap between spiral case and wind wheel, reduce the gas leakage between wind wheel and cover plate further, improve the aspect of blowing efficiency of blower;
4) top of ring baffle is provided with rounding, prevents noise from producing.

Fig. 2 is the stereogram of blower in embodiment;
Fig. 3 is the exploded view of blower in embodiment;
Fig. 4 is the plan view of blower in embodiment;
Fig. 5 is A-A sectional view in Fig. 4;
Fig. 6 is B-B partial enlarged drawing in Fig. 5;
Fig. 7 is the stereogram of embodiment's cover plate.
Embodiment:
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Embodiment one: as shown in Figures 2 to 7, the present embodiment is a kind of blower, comprise motor 1, spiral case 2, cover plate 3 and wind wheel 4, spiral case 2 and cover plate 3 are installed together and form a cavity 21, wind wheel 4 is positioned at inside cavity 21, motor 1 is arranged on spiral case 2 and the axle stretch end 11 of motor 1 extend into inside cavity 21 and links together with wind wheel 4, intake grill 31 is offered in the centre of cover plate 3, the side of spiral case 2 is provided with exhaust outlet 22, intake grill 31, exhaust outlet 22 is all communicated with cavity 21, centered by intake grill 31, the interior sidewall surface of cover plate 3 is provided with multiple annular relief 32.From the center of cover plate 3 toward the outer ledge of cover plate 3, the height of annular relief 32 reduces gradually.The shape of cross section of described annular relief 32 is triangular in shape.The shape of cross section of described annular relief 32 is trapezoidal.The outer ledge of cover plate 3 interior sidewall surface is provided with ring baffle 33, and the bottom of wind wheel 4 extend in the middle of ring baffle 33.The top of ring baffle 33 is provided with rounding 331.
Above embodiment is better embodiment of the present invention; but embodiments of the present invention are not limited thereto; other are any do not deviate from Spirit Essence of the present invention and principle under do change, modification, substitute, combine, simplify; be the substitute mode of equivalence, be included within protection scope of the present invention.
