Description
Technical field
The utility model is related to ventilation fan field, more particularly to a kind of snail road ventilation fan.
Background technology
Ventilation fan is to drive fan blade rotation driving air-flow by motor, a kind of air adjustment electricity for exchanging indoor and outdoor air
Device.The purpose of ventilation is to remove indoor foul atmosphere, adjusts temperature, humidity and sensory effect.Ventilation fan is widely used in
Family and public place.
Existing ventilation fan would generally set a sealing plate at ventilation opening, and sealing plate can play the sealing function to air passage,
But then, the air-flow in air passage can directly collide sealing plate in circulation, make to form vortex and noise in air passage, influence to take a breath
The using effect of fan.
Therefore, have increasing need for that a kind of airflow effect is good, ventilation fan of low noise in the market.
Utility model content
Based on this, the purpose of this utility model is that, a kind of snail road ventilation fan is provided, with it is simple in structure, mixed flow is few,
The advantages of low noise.
A kind of snail road ventilation fan, including housing, wind wheel and pedestal, the housing is fixed on the pedestal；The pedestal
Middle part offer ventilation opening, the wind wheel is rotatably arranged at the ventilation opening of the pedestal；The one side of the housing is provided with
Air outlet forms a ventilation snail road between the wind wheel and the housing；Snail road is additionally provided on the inside of the air outlet of the housing
Sealing plate, snail road sealing plate are fixed on the pedestal, and the upper surface of snail road sealing plate is arc-shaped.
The snail road ventilation fan of the utility model, not only can be to ventilation by the way that the upper surface of snail road sealing plate is arranged to arc
Snail road is sealed, and can also be that the gas in ventilation snail road is oriented to, and is made gas flowing more smooth, is reduced gas and snail road is sealed
The collision of plate and housing air outlet, surface form mixed flow and noise in ventilation snail road, in the ventilation fan for solving the prior art
Gas easily collides the problem of housing forms mixed flow and noise.
Further, installing plate is further included, the installing plate is fixed on the side of the pedestal, is set on the installing plate
It is equipped with mounting hole.
Further, ventilator is further included, the ventilator is fixed on the air outlet of the housing.
Further, the housing be located on the pedestal.
Further, the housing is in scroll casing shape.
Compared with the prior art, the snail road ventilation fan of the utility model by the upper surface of snail road sealing plate by being arranged to arc
Shape can not only be sealed ventilation snail road, can also be that the gas in ventilation snail road is oriented to, and make gas flowing more suitable
Freely, collision of the gas to snail road sealing plate and housing air outlet is reduced, surface forms mixed flow and noise in ventilation snail road, solves
Gas easily collides the problem of housing forms mixed flow and noise in the ventilation fan of the prior art.The snail road ventilation fan tool of the utility model
Have the advantages that simple in structure, mixed flow is few, low noise.
In order to better understand and implement, the utility model is described in detail below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the structure diagram of the snail road ventilation fan of the utility model.

Fig. 3 is the structure diagram of pedestal.
Specific embodiment
- Fig. 3 is please referred to Fig.1, Fig. 1 is the structure diagram of the snail road ventilation fan of the utility model, and Fig. 2 is the utility model
Snail road ventilation fan partial structural diagram, Fig. 3 is the structure diagram of pedestal.The snail road ventilation fan of the utility model, bag
Housing 10, wind wheel 20 and pedestal 30 are included, the housing 10 is fixed on the pedestal 30；The middle part of the pedestal 30 offers logical
Air port 31, the wind wheel 20 are rotatably arranged at the ventilation opening 31 of the pedestal 30；The one side of the housing 10 is provided with outlet air
Mouthful, a ventilation snail road is formed between the wind wheel 20 and the housing 10；Snail is additionally provided on the inside of the air outlet of the housing 10
Road sealing plate 40, snail road sealing plate 40 are fixed on the pedestal 30, and the upper surface of snail road sealing plate 40 is arc-shaped.
Sealing plate 40 upper surface in the snail road is arranged to arc, ventilation snail road can be not only sealed, can also be
The gas divulged information in snail road is oriented to, and is made gas flowing more smooth, is reduced gas to 10 air outlet of snail road sealing plate 40 and housing
It collides, surface forms mixed flow and noise in ventilation snail road.
For the ease of installation, the snail road ventilation fan of the present embodiment is preferably provided with installing plate 50, the installing plate 50
It is fixed on the side of the pedestal 30, mounting hole is provided on the installing plate 50.
The present embodiment is preferably provided with a ventilator 60 on the air outlet of the housing 10.The shell of the present embodiment
Body 10 is in scroll casing shape, and the housing 10 preferably be located on the pedestal 30.
Compared with the prior art, the snail road ventilation fan of the utility model by the upper surface of snail road sealing plate by being arranged to arc
Shape can not only be sealed ventilation snail road, can also be that the gas in ventilation snail road is oriented to, and make gas flowing more suitable
Freely, collision of the gas to snail road sealing plate and housing air outlet is reduced, surface forms mixed flow and noise in ventilation snail road, solves
Gas easily collides the problem of housing forms mixed flow and noise in the ventilation fan of the prior art.The snail road ventilation fan tool of the utility model
