As long as the humidifier can spray, it means that the oscillator has been working. ② Listen to the noise method. When the oscillation of the humidifier is very weak, the "spring" produced by the energy exchange plate is not obvious. If it is unable to determine whether it vibrates, you can find half of the conductor radio in the no station position, turn on the volume close to the humidifier (within 30cm apart), and then turn on the power switch of the humidifier. If noise interference can be received at this time (the noise is affected by the fog volume control potentiometer, that is, when the fog is large, the oscillation is strong and the noise is large; when the fog is small, the oscillation is weak and the noise is small). On the contrary, if the noise is not received, the humidifier does not oscillate. < / span > < span style = "font family: Microsoft YaHei; color: rgb (51, 51, 51); letter spacing: 0pt; font size: 12pt;" > < o: P > < / O: P > < / span > and

After the humidifier is used for a period of time, it is easy to have small or no fog (for example, only the spray column does not fog in the form of fountain), which is mainly caused by scaling, low efficiency or depolarization failure of the energy exchange plate. < / span > < span style = "font family: Microsoft YaHei; color: rgb (51, 51, 51); letter spacing: 0pt; font size: 12pt;" > < o: P > < / O: P > < / span > and
The method of judging the quality of the transducer is as follows: first of all, see whether the transducer is broken or defective, whether the silver layer on the surface is smooth or not, whether there is peeling or bubbling. If bubbling occurs and the thin silver layer partially falls off and the brown crystal (piezoelectric ceramic) inside is exposed, it means that the energy exchange plate is extremely inefficient or ineffective. Use a megohmmeter or a multimeter at R & times; 10K to test for leakage or breakdown. Its leakage is mostly due to the aging and leakage of waterproof gasket, which makes the reverse side of the energy exchange piece affected by damp or dirt. Can use anhydrous alcohol cotton to wipe the dirt on the front and back sides and dry it with electric hair dryer, which can generally return to normal. < / span > < span style = "font family: Microsoft YaHei; color: rgb (51, 51, 51); letter spacing: 0pt; font size: 12pt;" > < o: P > < / O: P > < / span > and
In addition, in order to ensure the normal operation of the humidifier and prolong the service life of the energy exchange plate, it is necessary to ensure that the humidifier can work normally. It is necessary to clean and descale the energy exchange plate frequently. You can buy the cleaning agent recommended by the manufacturer to clean the surface of the transducer once a week. You can also use a degreasing cotton or a soft brush dipped in vinegar (white vinegar is recommended) to gently wipe the surface of the transducer, and then rinse it with water. < / span > < span style = "font family: Microsoft YaHei; color: rgb (51, 51, 51); letter spacing: 0pt; font size: 12pt;" > < o: P > < / O: P > < / span > and
