Description
Technical field
The utility model is related to the technical field of blower fan, more particularly to a kind of impeller is arranged on the air draught type wind of air inlet
Machine.
Background technology
Blower fan is very common a kind of blowing apparatus in people's daily life, and it is widely used in the daily life of people
It is living, and be widely used in all trades and professions, but the airflow effects of some blower fans of the prior art can not expire well
The daily demand of sufficient people, because impeller is usually that at air outlet, impeller and motor can also be sent especially when rotating
Big noise, is lived under noise for a long time, is had a great impact for healthy, and impeller is at air outlet
Operating efficiency is not high, and air quantity is small.
Utility model content
There is provided a kind of easy to use, simple in construction, noise is small, work in view of the existing deficiencies of the prior art for the utility model
Make the air draught type blower fan of efficiency high.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of impeller is arranged on the air draught type blower fan of air inlet, including casing, and casing internal is provided with impeller and motor,
The motor is rotated by rotating shaft impeller, and the casing has air inlet and an air outlet, the impeller be arranged on into
At air port.
Preferably, the impeller includes baffle plate and fan blade, the fan blade is located at the upper surface of baffle plate.
Preferably, the width of the air inlet is less than the diameter of impeller.
Preferably, the casing includes upper shell and lower house, upper shell and lower house are to be detachably connected.
Preferably, the fan blade be provided with it is multiple.
Preferably, being additionally provided with controlling switch on the lower house, the controlling switch is electrically connected with motor.
The utility model has the beneficial effect that：The utility model is novel in design, simple in construction, and impeller is arranged on into air inlet
Place so that air can be rapidly inhaled into, and then be excluded by air outlet, added its air draught efficiency, will be entered in addition
The width design in air port is the diameter less than impeller, and the elimination for noise serves very big effect, is the use of people
Create a quiet environment；In addition, designed by using air draught type, only air outlet, it is not necessary to set lock air port is this to set
Count noise very little, it is very pure.
For the specific purposes and work(for more clearly illustrating architectural feature of the present utility model, technological means and its being reached
Can, the utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：

Embodiment
As shown in Figure 1-2, present embodiment uses following technical scheme：A kind of impeller is arranged on the suction of air inlet
Wind formula blower fan, including casing 1, casing 1 are internally provided with impeller 2 and motor 3, and the motor 3 is connected by rotating shaft with impeller 2
Connect, impeller 2 includes baffle plate 4 and fan blade 5, the fan blade 5 is located at the upper surface of baffle plate 4.The upper end of casing 1 is provided with air inlet
6, the impeller 2 is arranged at air inlet 6, and the width of the air inlet 6 is less than the diameter of impeller 2, and the bottom of the casing 1 is set
It is equipped with air outlet 7.Designed by using air draught type, only air outlet, it is not necessary to set lock air port, this design noise very little, very
Pure, the casing 1 includes upper shell 8 and lower house 9, and upper shell 8 and lower house 9 are to be detachably connected.The fan blade 5 is provided with
It is multiple.Controlling switch 10 is additionally provided with the lower house 9, the controlling switch 10 is electrically connected with motor 3.
When in use, motor 3 is controlled by controlling switch 10, the impeller 2 of motor 3 is rotated, impeller 2 drives wind
Leaf 5 is rotated, and air is flowed by centrifugal action, is sucked by air inlet 6, is assigned to edge by impeller 2, is then flowed downward, most
Flowed out afterwards by air outlet 7.
It is described above, only it is preferred embodiment of the present utility model, not to limit the utility model, thus it is every
Any modification, equivalent substitution and improvements actually made according to technology of the present utility model to above example etc., still fall within this
In the range of utility model technical scheme.
