Description
Technical Field
The invention relates to the field of ventilation devices and air purification, in particular to a window ventilation valve and a fresh air system, wherein a solar cell is arranged on the window ventilation valve, and the window ventilation valve can be automatically opened and closed.
Background
With the development of society, people's requirements for quality of life are continuously increasing. Among them, air quality is one of the important factors that people are very concerned with. However, the air quality of the current living environment is mainly threatened by three aspects:
first, with the continuous advancement of industrialization and urbanization, the haze weather increases, which results in serious degradation of air quality, especially increase of PM2.5 solid particle content, and these solid particles cause diseases of respiratory system, cardiovascular system, blood system, reproductive system, etc., such as inflammation of pharyngolaryngitis emphysema, asthma, rhinitis, bronchitis, etc.;
secondly, various home decorations can emit a large amount of volatile organic matters, such as formaldehyde and the like, and the pollutants can cause allergic dermatitis, color spots, necrosis, even bronchial asthma and the like;
third, in a closed environment (e.g., a room lacking ventilation), exhalation by a person can cause the carbon dioxide content of the air to increase over time, thereby stimulating the respiratory center of the person, causing shortness of breath, increased smoke inhalation, and even causing symptoms such as headache, mental confusion, etc.
In order to improve the three air quality problems and improve the air quality of the living environment of people, more and more families in recent years start to install a fresh air system. The basic principle of the fresh air system is to suck air from the outside and discharge clean air into the room through the filtration of a high efficiency filter screen (HEPA). While air of poor quality is exhausted from the other side of the room.
Therefore, the fresh air system has the following two functions:
firstly, reducing solid particles in air;
second, carbon dioxide in the air is reduced.
It should be noted that, according to the basic principle of the fresh air system, an exhaust valve needs to be installed at the other side of the room to exhaust the air with poor quality out of the room. In order to reduce damage to the room, the vent valve is primarily mounted on the window, referred to as a window vent valve. The existing through-window air valve has a plurality of forms, but generally has two obvious defects:
firstly, the fresh air system cannot be automatically opened and closed, so that outdoor air is often filled back into a room when the fresh air system runs at a small air quantity, and the indoor air is polluted;
the exhaust direction of the second air outlet is horizontal, so that rainwater often enters a room in rainy days, and the indoor objects can be wet.
Based on the two disadvantages, a novel window ventilation valve is to be proposed to solve the problems in the prior art.
