Humidifier is a household appliance to increase indoor humidity. Humidifier can humidify the designated room, or connect the boiler or central air conditioning system to humidify the whole building.
Common types:
ultrasonic humidifier
It has been widely used in various fields. The ultrasonic humidifier atomizes water into ultrafine particles and negative oxygen ions of 1 micron to 5 microns by using high-frequency ultrasonic vibration of 2 million times per second, thus realizing uniform humidification, refreshing air, improving health, changing the dryness and heat of heating in winter and creating a comfortable living environment.
Pure humidifier
Direct evaporative humidifier is also commonly known as pure humidifier. Pure humidification technology is a new technology just adopted in the field of humidification. Through molecular sieve evaporation technology, calcium and magnesium ions in water are removed, and the problem of "white powder" is completely solved. Washing air through water curtain can filter and purify germs, dust and particles in the air at the same time of humidification, and then send humid and clean air into the room through pneumatic device, thus improving environmental humidity and cleanliness. Therefore, it is very suitable for families with old people and children, and can also prevent winter flu germs.
Ultrasonic humidifier and pure humidifier are the first choice products recommended to children, with high safety factor, strong air purification, sterilization and humidification ability, promoting health and giving children a comfortable environment.
Electric heating humidifier
Thermal evaporation humidifier is also called electric humidifier. Its working principle is to heat water to 100℃ in a heater to generate steam, which is emitted by a motor. Electric heating humidifier is the simplest way to humidify.
Immersed electrode humidifier
Immersed electrode humidifier uses a large area electrode immersed in water as the terminal and water as the heating medium. When electric current transfers electric energy through water, it generates heat, which makes water boil and produces steam. Its characteristics are low cost, convenient installation and use, but low precision, which needs regular replacement and maintenance.
Cold fog humidifier
This humidifier uses a fan to force the air to contact and exchange with water when passing through the water-absorbing medium, so as to increase the relative humidity of the air. The characteristic of this humidifier is that it can automatically adjust with the relative humidity of air, that is, the humidification amount is large when the relative humidity of air is low and small when the relative humidity of air is high; The disadvantage is that the humidification amount is low (about 1/5 of that of ultrasonic humidifier) and the noise is higher than that of ultrasonic humidifier, but this humidifier consumes less energy and has low noise.
Commercial humidifier
Commercial humidifier is a kind of humidifying equipment with moderate spray quantity between civil and industrial use.
Humidification hazard
Indoor air humidification can be carried out by sprinkling water, putting pots, etc., but the most convenient way is to use a humidifier. Many families have bought humidifiers, which are on 24 hours a day. However, experts point out that humidifiers will increase the possibility of respiratory diseases.
When the humidifier is in use, it must be cleaned regularly, otherwise microorganisms such as mold in the humidifier will enter the air with steam mist, and then enter the human respiratory tract, which is easy to get humidifier pneumonia. In addition, the higher the humidity of the air, the better. In winter, the comfortable humidity is around 50%. If the air humidity is too high, people will feel chest tightness and difficulty breathing, so moderate humidification is better.
In order to improve the indoor dry environment, many families use humidifiers. While people enjoy humid air, indoor bacteria also grow and multiply in this environment, which is the chief culprit of pneumonia and respiratory diseases.
This disease is called "humidifier pneumonia" by doctors, which is similar to the common "air conditioning disease" in summer. It is that harmful microorganisms enter the human respiratory tract through the air and cause inflammation.
Once the temperature and humidity are appropriate, all kinds of microorganisms floating in the air and scattered in dust and articles will grow and multiply rapidly, and people with relatively weak resistance, such as the elderly and children, are prone to infection after inhaling bacteria. In addition to bacteria, common indoor microorganisms in winter include molds and actinomycetes, which can cause pneumonia or respiratory diseases. Phlegm cough caused by such diseases will also accelerate the spread of bacteria.
Put a wet towel on the heater. Personally, I think that heating will evaporate the moisture on the wet towel and give the room a certain humidification effect.
There are several pots of green plants in the house. Don't think that green plants are just ornamental. They are the best humidifiers, which are safe and energy-saving. It is recommended to raise rich and precious bamboo and the like.
If you want to eat more fruits, you can drink more rock sugar and Sydney juice, which can alleviate the physical discomfort caused by dryness.
Often open the window for ventilation, and the natural air is better.
