What is a computer humidifier

　　The computer humidifier, also known as USB humidifier, uses the principle of ultrasonic high-frequency oscillation to atomize water into 1-5 μ m ultra-fine particles and diffuse the water mist into the air, so as to achieve the purpose of uniformly humidifying the air. Humidifier is divided into ultrasonic humidifier, pure humidifier and electric humidifier.

　　In fact, the principle of computer humidifiers is basically the same as that of ordinary humidifiers. Both of them use the principle of ultrasonic high-frequency oscillation. Because the power supply voltage of computers is generally DC5V, 800mA, the power of the transducer (also known as the oscillating plate, which converts electrical energy into mechanical energy), a key component of computer humidifiers, is very small, so the efficiency of atomization is extremely low. Because there are very few manufacturers of transducers in the market, but Japan has done a good job, However, it is expensive. In order to save costs, most manufacturers use transducers made in China. The quality is very unstable. It often happens that the machine cannot atomize after working for a period of time, or there is no atomization at all, which will not play a role in humidification. This is a conceptual product, which is generally not practical, and it is also very inconvenient to change water. Some products can be compatible with purified water bottles. You can directly buy bottled purified water and connect it to the corresponding water inlet of the product. It is relatively convenient. At present, the retail price of this product in China is generally about 50~100 yuan, but the production cost is less than 30 yuan. And the humidification effect can not be achieved. If you want to achieve the ideal humidification effect, it is recommended that you go to the supermarket and directly buy some well-known domestic brands. This type of humidifier can be directly connected to the wall socket. It has high atomization efficiency, and it is convenient to add water. The quality is guaranteed, because the domestic energy exchanger of the humidifier connected to the mains power (AC220) has been very good. And the technology is quite perfect.

　　The main function of humidifier is to maintain indoor air humidity. If the indoor ambient humidity is above 50%, the survival rate of cold virus is extremely low. The humidifier atomizes water in a variety of ways to keep the room relatively high humidity and produce a certain amount of natural negative oxygen ions, which can treat and relieve influenza, hypertension, tracheitis and other diseases, and play a protective role in the nervous system, cardiovascular system and human metabolism. USB humidifier can not meet the humidity requirements of indoor environment due to its low power, but creates a better environment for bacterial reproduction.
