Description
Technical field
The utility model is related to ventilation device field, air purification field, more particularly to a kind of forms ventilation valve and new
Wind system, which is equipped with solar cell, and can realize automatic shutter.
Background technology
With the development of society, requirement of the people to quality of life is continuously improved.Wherein, air quality is that people are closed very much
One of an important factor for cutting.However, the air quality of living environment is mainly threatened by three aspects at present：
First, with the continuous propulsion of industrialization and urbanization, haze weather gradually increases, under causing air quality serious
Drop, the especially increase of PM2.5 solid contents, these solid particles cause respiratory disease, disease of cardiovascular system,
The diseases such as hematological system, reproductive system, the inflammation such as sphagitis pulmonary emphysema, asthma, rhinitis, bronchitis；
The second, various house fitting-ups can also distribute a large amount of volatile organic matter, such as formaldehyde, these pollutants may draw
Play allergic dermatitis, color spot, necrosis, even bronchial asthma etc.；
(as lacked room with good ventilation) in third, enclosed environment, the expiration of people can lead to the carbon dioxide in air
Content increases over time and constantly, thus stimulates the respiratory center of people, causes to be short of breath, and flue gas soakage increases
Add, or even the symptoms such as headache, unconsciousness can be caused.
In order to improve above-mentioned three aspects air quality problems, the air quality of raising people's living environment was more next in recent years
More families starts to install fresh air system.Fresh air system basic principle passes through efficient filter from outdoor sucking air
(HEPA) filtering will be discharged to interior in clean clean air.Simultaneously by second-rate air from the other side in room
Discharge.
Therefore, fresh air system has following both sides effect：
The first, the solid particle in air is reduced；
The second, the carbon dioxide in air is reduced.
It should be pointed out that according to the basic principle of fresh air system, need the other side in room that air bleeding valve is installed, it will
Second-rate air discharge is outdoor.In order to reduce the destruction to room, ventilation valve is mostly installed on forms, referred to as forms
Ventilation valve.Existing logical forms air-valve has many forms, but is usually present two apparent disadvantages：
The first, it is unable to automatic shutter, thus causes fresh air system usually to occur outdoor air when small air quantity is run and pours in down a chimney
To interior, and then room air is caused to be contaminated；
The second, the discharge directions of gas outlet are that horizontal direction rainwater entrance usually occurs thus in rainy weather
Interior, and then indoor object may be caused moist.
Based on above-mentioned two disadvantage, need to be proposed a kind of novel forms ventilation valve, it is above-mentioned in the prior art to solve
Problem.
