Description
Technical field
This utility model relates to field of engineering technology, particularly relates to a kind of blower fan.
Background technology
Blower fan is dependent on the mechanical energy of input, improves gas pressure and supplies gas side by side the machinery of body, and it is a kind of driven stream
Body machinery.
Blower fan is that the custom of gas compression and gas conveying machinery is called for short by China, and usually said blower fan includes: ventilate
Machine, aerator, wind-driven generator.Gas compression and gas conveying machinery be rotate mechanical energy be converted to gas pressure can and
Kinetic energy, and the machinery that gas is transferred out.The main structural components of blower fan is impeller, casing, air inlet, support, motor, skin
Belt wheel, shaft coupling, deafener, driving member (bearing) etc..
Unpowered ventilation machine is the air thermal convection current utilizing natural wind and indoor and outdoor temperature difference to cause, and promotes turbine to rotate
Thus utilize centrifugal force and underbalance effect to be discharged by indoor stale hot-air.Blower fan is related to the transmission & distribution energy consumption of system, is
The part that building energy conservation is the most crucial.A lot of wind is shown according to air-conditioning equipment Quality Supervision and Inspection Center of country aerator supervision for many years
Machine is problematic in that under declared working condition, it is therefore desirable to require to produce and manufacture blower fan in strict accordance with product standard.
Existing blower fan noise in running is big, and cannot filter the dust in air, does not have purification
Function.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of blower fan.
This utility model is to be achieved through the following technical solutions:
A kind of blower fan, including body fuselage, cylindrically, described body fuselage side is provided with described body fuselage entirety
Air inlet, opposite side is provided with steam vent, and described body fuselage inner hub location is provided with driving motor, described driving motor
Outfan is connected with impeller, and described driving motor is connected with body fuselage by fixed support, sets inside described body fuselage
It is equipped with wind scooper, the medial wall of described body fuselage is provided with puigging, described body fuselage medial wall is provided with two groups
Spacing block set, described spacing block set is connected with the first drainage screen, the second drainage screen respectively.
As optimal technical scheme of the present utility model, described puigging covers on the medial wall of body fuselage, and thick
Degree is 3mm～5mm.
As optimal technical scheme of the present utility model, described first drainage screen, the second drainage screen are V-shaped, and wedge angle
Direction is towards air intake direction.
As optimal technical scheme of the present utility model, described first drainage screen, the second drainage screen filtering accuracy gradually
Improve.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, by arrange every
Sound-absorbing layer, the first drainage screen and the second drainage screen, the most operationally, puigging can effectively absorb blower fan in running
Partial noise, effectively reduce the operation noise of blower fan, and can be effectively to air at the first drainage screen and the second drainage screen
In dust filter, it is simple to the purification in air, environment protecting is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
Referring to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of blower fan, including body fuselage 1, cylindrically, described body fuselage 1 side sets described body fuselage 1 entirety
Being equipped with air inlet 101, opposite side is provided with steam vent 102, and described body fuselage 1 inner hub location is provided with driving motor 2,
Described driving motor 2 outfan is connected with impeller 3, and described driving motor 2 is connected with body fuselage 1 by fixed support 4, institute
State body fuselage 1 and be internally provided with wind scooper 5, the medial wall of described body fuselage 1 is provided with puigging 6, wherein said every
Sound-absorbing layer 6 covers on the medial wall of body fuselage 1, and thickness is 3mm～5mm, and such puigging 6 can realize reducing noise.
Being provided with two groups of spacing block sets 103 on described body fuselage 1 medial wall, described spacing block set 103 is respectively with first
Drainage screen the 7, second drainage screen 8 is connected, and wherein said first drainage screen the 7, second drainage screen 8 is V-shaped, and wedge angle direction court
To air intake direction, and the filtering accuracy of described first drainage screen the 7, second drainage screen 8 gradually steps up.The most operationally, sound insulation
Layer 6 can effectively absorb blower fan partial noise in running, effectively reduces the operation noise of blower fan, and first
Dust in air can effectively be filtered by drainage screen 7 with the second drainage screen 8, it is simple to the purification in air, environment protecting
Good.
In description of the present utility model, unless otherwise clearly defined and limited, term " install ", " being connected ", " even
Connect ", " fixing " should be interpreted broadly, connect for example, it may be fixing, it is also possible to be to removably connect, or integral；Permissible
