The utility model discloses a set up first cavity, second cavity, an one kind ventilation fan and the 2nd one kind ventilation fan, when using like this, an one kind ventilation fan and the 2nd one kind ventilation fan start simultaneously for gaseous exchange speed has been accelerated with indoor air suction, second cavity with outdoor air suction like this to first cavity, has improved exchange efficiency, and is effectual.
Description
Technical field
The utility model relates to technical field of electric appliances, particularly relates to a kind of ventilation fan.
Background technique
Ventilation fan drives fan blade rotary actuation air-flow by motor, the class air adjustment electricity-saving appliance that indoor and outdoor air is exchanged.Also known as ventilation fan.The object of ventilation is exactly to remove indoor vitiated air, regulates temperature, humidity and sensory effect.Ventilation fan is widely used in family and public place.
The scavenging way of ventilation fan has discharge formula, inhalation type by formula three kinds.Discharge formula enters air from natural inflow mouth, discharges vitiated air by ventilation fan; Inhalation type, by ventilation fan inhale fresh air, discharges vitiated air from natural relief opening; And be that air-breathing has been come by ventilation fan with exhaust by formula.Fan blade rotary actuation air-flow is driven, the class air adjustment electricity-saving appliance that indoor and outdoor air is exchanged by motor.Also known as ventilation fan.The object of ventilation is exactly to remove indoor vitiated air, regulates temperature, humidity and sensory effect.Ventilation fan is widely used in family and public place.
Existing ventilation fan generally only has one to fan head, can only realize entering air or discharging air, causes the efficiency of gas exchanges low like this, weak effect.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of ventilation fan.
The utility model is achieved through the following technical solutions:
A kind of ventilation fan, comprise ventilation fan body, dividing plate is provided with in the middle part of described ventilation fan body, described ventilation fan body forms the first cavity, the second cavity under the effect of dividing plate, described first cavity inside is provided with air intake pipe and the first ventilation fan, described second cavity inside is provided with air outlet tube and the second ventilation fan, and described ventilation fan body air intake is provided with fixed cover, on described fixed cover and be positioned at the first cavity, the second cavity wind inlet place is provided with air inlet grid.
As optimal technical scheme of the present utility model, the flabellum sense of rotation of described first ventilation fan, the second ventilation fan is contrary.
As optimal technical scheme of the present utility model, be welded to connect between described dividing plate and ventilation fan body.
As optimal technical scheme of the present utility model, described air inlet grid is embedded on fixed cover.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model by arranging the first cavity, the second cavity, the first ventilation fan and the second ventilation fan, when using like this, first ventilation fan and the second ventilation fan start simultaneously, indoor air is sucked by the first cavity, and outdoor air sucks by the second cavity, accelerates the exchange velocity of gas like this, improve exchange efficiency, effective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. ventilation fan body; 101. first cavitys; 102. second cavitys; 2. suction tude; 3. air outlet tube; 4. the first ventilation fan; 5. the second ventilation fan; 6. fixed cover; 7. air inlet grid.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of ventilation fan, comprise ventilation fan body 1, be provided with dividing plate 103 in the middle part of described ventilation fan body 1, described ventilation fan body 1 forms the first cavity 101, second cavity 102 under the effect of dividing plate 103, is welded to connect between wherein said dividing plate 103 and ventilation fan body 1.Described first cavity 101 inside is provided with air intake pipe 2 and the first ventilation fan 4, described second cavity 102 inside is provided with air outlet tube 3 and the second ventilation fan 5, the flabellum sense of rotation of wherein said first ventilation fan 4, second ventilation fan 5 is contrary, side air inlet can be realized like this, side is vented, and improves the exchange velocity of air.
Described ventilation fan body 1 air intake is provided with fixed cover 6, and described fixed cover 6 is positioned at the first cavity 101, second cavity 102 wind inlet place and is provided with air inlet grid 7, and wherein said air inlet grid 7 is embedded on fixed cover 6.During such use, the first ventilation fan 4 and the second ventilation fan 5 start simultaneously, and indoor air is sucked by the first cavity 101, and outdoor air sucks by the second cavity 102, accelerates the exchange velocity of gas like this, improves exchange efficiency, effective.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
