What is the working principle of an electric heater

At present, the products in the household humidifier market are mainly divided into three categories: ultrasonic humidifiers, direct steam humidifiers, and hot steam humidifiers. Ultrasonic technology is a relatively mature technology in the world and has been widely applied in various fields. The ultrasonic humidifier uses high-frequency ultrasonic oscillation to atomize water into 1-5 microns of ultrafine particles. Through a pneumatic device, the water mist is diffused into the air, making the air moist and accompanied by rich negative oxygen ions. It can freshen the air, improve health, change the dry and hot winter heating, and create a comfortable living environment. According to experts, the advantages of ultrasonic humidifiers are high humidification intensity, uniform humidification, and high humidification efficiency; Energy saving and power saving, with only 1/10 to 1/15 of the power consumption of electric heaters; Long service life, automatic humidity balance, and automatic protection without water; It also has functions such as medical atomization, cold compress bath surface, and jewelry cleaning. The disadvantage is that there are certain requirements for water quality. Direct steam humidifiers are also commonly referred to as pure humidifiers. Pure humidification technology is a new technology that has just been adopted in the field of humidification. Pure humidifiers use molecular sieve evaporation technology to remove calcium and magnesium ions from water, completely solving the problem of "white powder". Wash the air through a water curtain, humidify the air while purifying it, and then send the moist and clean air indoors through a pneumatic device, thereby increasing environmental humidity. At the same time, the new humidifier is not limited by water quality; The filter evaporator is made of imported single fiber, which can filter air and kill bacteria, making humidification more pure; Equipped with an air circulation system, while humidifying, the air is washed with clean water, effectively eliminating pollution in the air, purifying the air, promoting indoor air circulation, and ensuring human health to a greater extent. A hot steam type humidifier is also known as an electric heating tube humidifier. Its working principle is to heat water in a heating body to 100 degrees, generate steam, and use an electric motor to send the steam out. So electric heating humidifier is the simplest humidification method in technology, but its disadvantages are high energy consumption, inability to dry burn, low safety factor, and easy scaling on the heater. The market outlook is not optimistic. Compared to the above three types of double ended electric heating pipes, the humidifier electric heater has no "white powder" phenomenon in use, low noise, but high power consumption, and is prone to scaling on the humidifier; The pure humidifier has no "white powder" phenomenon or scaling, low power, and has an air circulation system that can filter air and kill bacteria; Ultrasonic humidifiers have high and uniform humidification intensity, low power consumption, and long service life. They also have functions such as medical atomization, cold compress on bath surfaces, and jewelry cleaning. However, they have certain requirements for water quality, and there may be slight "white powder" phenomenon during use. Therefore, ultrasonic humidifiers and pure humidifiers are still recommended as the preferred products
