The most common household humidifier Atomizer Plate is the ultrasonic humidifier, which keeps producing mist.
The high-frequency vibration of the Atomizer Plate breaks water into small droplets of 1 to 10 microns. The water still exists in liquid form. The water mist diffuses into the air, increasing the contact area with the air, accelerating evaporation, and increasing the humidity of the air.
Therefore, the purpose of the humidifier Atomizer Plate is to turn water from liquid to gas. This process is called vaporization.
There are two ways of vaporization, evaporation and boiling. The humidifier will definitely not choose the boiling method. Boiling consumes a lot of power. It is too expensive just for humidification.
Therefore, using water evaporation to achieve the humidification effect is the most appropriate way. In daily life, drying wet clothes can also be regarded as humidifying the air, but the evaporation rate of water in a natural state is too slow to quickly increase the humidity of the air.
We need to increase the evaporation rate of water. Take hair drying as an example. Hot air dries faster than cold air, cold air dries faster than no air drying, strong air dries faster than weak air, and constant stirring dries faster than fixed air drying.
From this, we can know that three factors will affect the evaporation rate of water, temperature, surface area of the liquid, and the speed of air flow on the liquid surface.
The mistless Humidifier Atomizer Plate uses the latter two factors to accelerate evaporation. The mistless humidifier generally consists of three parts: water tank, filter element, and fan.
It is called a filter element, but filtering is only an additional function. The essence of the mistless humidifier is water evaporation. Water evaporation does not diffuse into the air with impurities, and will naturally remain on the filter element.
Its real purpose is to increase the contact area between water and air. Under the same conditions, if a bowl of water is soaked in a honeycomb filter element, it will definitely dry faster than the original bowl of water!
The fan is naturally used to accelerate the air flow speed on the liquid surface. The wind blows outward, and a negative pressure area will be formed inside the humidifier. Air will be continuously poured into the humidifier, and the dust and hair outside will adhere to the filter element. In addition, the impurities in the water will make the filter element of the fogless humidifier particularly easy to get dirty. Infrequent cleaning will cause the filter element to mold and harden, and the humidification effect will become worse and worse.
The above is the core principle of the fogless humidifier. If you also understand temperature, surface area and air flow rate, it is very simple to make a simple humidifier yourself.
