Description
Technical field
This utility model relates to the axial flow blower of a kind of ladder fan.
Background technology
Blower fan is being invented very early, is mainly used on the kitchen range top cooked the when of ancient times, and artificial pulls the kitchen range top
Inside blow, firewood can be blazed up faster.The use of blower fan slowly is increasing, and the most processed is more mechanical
Changing, be widely applied to every field, existing blower fan is the most essentially identical, is all by driven by motor main shaft, then
Arranging a fan on main shaft, fan rotates to produce after suction draws air into inside and discharges from air outlet.
Existing this blower fan structure, due to only one of which fan, the most relatively weak on suction, and motor also sets up
In the inside of blower fan, thus allowing inside create an obstruction, air cannot run toward air outlet after entering the most smoothly,
Reduce work efficiency and operation effectiveness.
Utility model content
This utility model mainly solves the technical problem existing for prior art, thus provide a kind of work efficiency good,
Operation effectiveness is good, suction is big, and the axial flow blower of the ladder fan of length in service life.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:
The axial flow blower of a kind of ladder fan of the present utility model, mainly by housing, motor, electric machine main shaft, transmission band, anti-
Dust hood, sheave, driven shaft, thin axle, the first fan, the second fan, three fan, filter screen, air inlet and air outlet composition；Described
Motor is positioned at the top of housing；Described first fan, the second fan, three fan are connected on thin axle side by side；Described transmission band
One end is connected on main shaft, and the other end is connected on driven shaft；Described filter screen is positioned at the front end of three fan.
As preferably, described dust cover is positioned at housing, and driven shaft is laterally positioned in dust cover.
As preferably, described sheave is set in one end of driven shaft, and is positioned at the inner side of transmission band.
As preferably, described air inlet is positioned at the front end of filter screen.
As preferably, described air outlet is positioned at the rear end of dust cover.
As preferably, described first fan, the second fan, the cause not of uniform size of three fan.
The beneficial effects of the utility model are: owing to the axial flow blower of ladder fan is provided with three fans, and size is not
One, which forms a stepped suction, the biggest suction draws air into, the most other two strands of suction, the stage
Direct air into the direction of air outlet, the most not only improve the overall suction of blower fan, accelerate outside efficiency, also allow the air can
Run toward air outlet more smoothly, improve the operation effectiveness of blower fan further；Transmission band, driven shaft and main shaft design allow
Motor can be arranged on the outside of blower fan, so greatly improves the space of blower interior, makes blower interior the most unobstructed；Filter
Impurity in air can be filtered by the design of net, prevents big impurity particle from entering into blower interior, causes blower fan
Damage, indirectly extend service life.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the structure chart of the axial flow blower of this utility model a kind of ladder fan.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent clearly
Define
As it is shown in figure 1, the axial flow blower of a kind of ladder fan, mainly by housing 1, motor 2, electric machine main shaft 3, transmission band 4,
Dust cover 5, sheave 6, driven shaft 7, thin axle the 8, first fan the 9, second fan 10, three fan 11, filter screen 12, air inlet 13 and
Air outlet 14 forms；Described motor 2 is positioned at the top of housing 1；Described first fan the 9, second fan 10, three fan 11 are side by side
It is connected on thin axle 8；Described transmission band 4 one end is connected on main shaft 3, and the other end is connected on driven shaft 7；Described filter screen 12
Front end in three fan 11.
Described dust cover 5 is positioned at housing 1, and driven shaft 7 is laterally positioned in dust cover 5.
Described sheave 6 is set in one end of driven shaft 7, and is positioned at the inner side of transmission band 4.
Described air inlet 13 is positioned at the front end of filter screen 12.
Described air outlet 14 is positioned at the rear end of dust cover 5.
Described first fan the 9, second fan 10, the cause not of uniform size of three fan 11.
The axial flow blower of this kind of ladder fan is when operation, and after motor 2 operation, main shaft 3 drives driven shaft by transmission band 4
7 start operation, thin axle 8 operation the most therewith, and air enters from air inlet 13, by filter screen 12 in entering into housing 1, and the first wind
Fan the 9, second fan 10, three fan 11 start to rotate, and produce big suction, allow air discharge from air outlet 14.
The beneficial effects of the utility model are: owing to the axial flow blower of ladder fan is provided with three fans, and size is not
One, which forms a stepped suction, the biggest suction draws air into, the most other two strands of suction, the stage
Direct air into the direction of air outlet, the most not only improve the overall suction of blower fan, accelerate outside efficiency, also allow the air can
Run toward air outlet more smoothly, improve the operation effectiveness of blower fan further；Transmission band, driven shaft and main shaft design allow
Motor can be arranged on the outside of blower fan, so greatly improves the space of blower interior, makes blower interior the most unobstructed；Filter
Impurity in air can be filtered by the design of net, prevents big impurity particle from entering into blower interior, causes blower fan
Damage, indirectly extend service life.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to
In this, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.
