Abstract
The utility model discloses a kind of air intake covers for blower, the air intake cover is located at the air inlet of the blower, the intermediate surface of the air intake cover is provided with multiple intermediate air inlet holes, the at least partially circumferentially side edge of the air intake cover is provided with multiple side air inlet holes, and the outer circumferential of the air intake cover has a divergent segment along air inlet direction.At least partially circumferentially side edge is provided with multiple side air inlet holes to the air intake cover, in this way when the intermediate air inlet hole of air intake cover is blocked, side air inlet hole equally may be implemented to enter the wind, substantially reduce blower caused by due to intermediate air inlet hole is blocked have some setbacks even failure；And the circumferential direction of air intake cover has a divergent segment along air inlet direction, since such a divergent segment exists, it is easy to slip under the action of suction along inclined-plane when the shelters such as paper or leaf are attached to air inlet cover outer wall, be realized to a certain extent from the function of removing obstacles.
Description
Technical field
The utility model relates to blower technical field more particularly to a kind of air intake covers for blower.
Background technique
Blower is to improve gas pressure by the mechanical energy of input and supply gas side by side the machinery of body, it is a kind of driven stream
Body is mechanical.Blower is to the habit abbreviation of gas compression and gas conveying machinery, and usually said blower includes ventilation blower, air blast
Machine, wind-driven generator etc..Blower is widely used in the ventilation of factory, mine, tunnel, cooling tower, vehicle, ship and building, row
The ventilation of dirt and cooling, boiler and industrial furnace and air inducing；Cooling and ventilation in the apparatus of air conditioning and domestic electric appliance；
It the drying of cereal and selects and recommends, inflation and propulsion of wind-tunnel wind regime and aircushion vehicle etc..
Existing blower is provided with an air intake cover in air inlet, is provided with air inlet hole on air intake cover, wind from air inlet hole into
Enter blower, such structure has the following problems: when there is shelter such as paper leaf etc. to block air inlet hole, will lead to air inlet
Being obstructed influences blower normal work, and shelter is not easy to fall.
Utility model content
Technical problem to be solved in the utility model is in view of the above drawbacks of the prior art, to propose a kind of for heat
The air intake cover of blower.
Realize the technical solution of the utility model aim are as follows: a kind of air intake cover for blower, the air intake cover position
In the air inlet of the blower, the intermediate surface of the air intake cover is provided with multiple intermediate air inlet holes, and the air intake cover is extremely
Small part circumferential direction side edge is provided with multiple side air inlet holes, and the outer circumferential of the air intake cover has an edge air inlet direction gradually
Expand section.
Further, the multiple side air inlet hole is located at the lower half circumferential direction side of the air intake cover.
Further, the multiple side air inlet hole includes being located at the medianly zygomorphic two groups of air inlet holes of air intake cover.
Further, the air intake cover is the cone to blower outer projection.
Further, the blower is air-heater.
The utility model has the following beneficial effects:
Compared with the existing technology, the utility model is innovatively using the air intake cover specially designed, the air intake cover at least portion
Circumferential side edge is divided to be provided with multiple side air inlet holes, in this way when the intermediate air inlet hole of air intake cover is blocked, side air inlet hole
Equally may be implemented to enter the wind, substantially reduce blower caused by due to intermediate air inlet hole is blocked have some setbacks even failure；And
The circumferential direction of air intake cover has a divergent segment along air inlet direction, and (limiting case is that air intake cover is circular cone to blower outer projection
Shape), since such a divergent segment exists, it is easy when the shelters such as paper or leaf are attached to air inlet cover outer wall in suction
Under the action of slip along inclined-plane, realized to a certain extent from the function removed obstacles.
Other than objects, features and advantages described above, there are also other purposes, feature and excellent for the utility model
Point.Below with reference to accompanying drawings, the utility model is described in further detail.
Detailed description of the invention
Fig. 1 is that the utility model air intake cover is installed on the schematic diagram on blower.
Fig. 2 is perspective view of the utility model for the air intake cover of blower.
Fig. 3 is side view of the utility model for the air intake cover of blower.
Fig. 4 is main view of the utility model for the air intake cover of blower.
Specific embodiment
With reference to the accompanying drawings of the specification, the utility model is further described.
In conjunction with Fig. 1-4, a kind of air intake cover 2 for blower 1, the air intake cover 2 is located at the air inlet of the blower 1,
The intermediate surface of the air intake cover 2 is provided with multiple intermediate air inlet holes 4, and at least partially circumferentially side edge of the air intake cover 2 is set
Multiple side air inlet holes 3 are equipped with, the circumferential direction of the air intake cover 2 has a divergent segment 5 along air inlet direction.
Further, the multiple side air inlet hole 3 is located at the lower half circumferential direction side of the air intake cover 2.
Further, the multiple side air inlet hole 3 includes being located at 2 medianly zygomorphic two groups of air inlet holes 3 of air intake cover.
Further, the air intake cover 2 is the cone to blower outer projection, this is the limiting case of divergent segment 5, i.e.,
Entire air intake cover is the circular cone of an evagination.
Further, the blower 1 is air-heater.
At least partially circumferentially side edge is provided with multiple side air inlet holes to the utility model air intake cover, in this way when air intake cover
When intermediate air inlet hole is blocked, side air inlet hole equally may be implemented to enter the wind, and substantially reduce due to intermediate air inlet hole is blocked
Caused by blower have some setbacks even failure；And the circumferential direction of air intake cover has a divergent segment along air inlet direction, and (limiting case is
Air intake cover is the cone to blower outer projection), since such a divergent segment exists, when the shelters such as paper or leaf
It is easy to slip under the action of suction along inclined-plane when being attached to air inlet cover outer wall, be realized to a certain extent from the function removed obstacles
Energy.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
