Background

In dry autumn and winter, the relative humidity of air is low, which has adverse effect on respiratory tract systems of people, and in order to humidify the air and increase the air humidity, the humidifier is produced. Most of the mainstream humidifiers in the market at present adopt an ultrasonic oscillation technology, so that water in the humidifier is changed into water mist with small water drops as a main form and is released into the air, and the water drops are difficult to directly increase the air humidity due to large water drops and easily drip onto a table top or the ground around the humidifier, so that the table top or the ground is wetted; if a user uses tap water, calcium and magnesium ions in the water are released into the air along with water drops, so that powdery mildew is easily formed on the surface of the house, and poor experience is caused for the user. The evaporative humidifier evaporates liquid water into gaseous water molecules through the air duct, and the gaseous water molecules are discharged into the air, so that the air humidity is directly and rapidly increased, the desk top or the ground cannot be wetted, and white powder is not generated. The existing evaporative humidifier on the market has the problems of low humidification efficiency, inconvenient water adding, inconvenient water tank cleaning and the like. The design of wind channel is optimized to this scheme, has effectively improved the humidification efficiency of humidifier, makes to add water, the water tank washs more conveniently, and the outward appearance is clean and tidy.
