1, ultrasonic humidifier had better use pure water for humidification, because the water quality in many areas is hard, that is to say, the content of calcium and magnesium ions is high, and some water purification agents such as bleaching powder are used in water treatment in water plants, which is very unfavorable for humidifier humidification. A part of calcium and magnesium ions are sprayed out together with the water mist, dispersed on the surface of objects and the ground, dried to form "white powder" scale, and the other part is deposited on the surfaces of energy conversion plates and water tanks. The formation of solid scale is caused by impure water quality. Moreover, the scaling on the surface of the transducer will affect the humidification effect, even if it is not cleaned in time, it will lead to the overload of the transducer and burn the transducer and electronic components.
2. Replace the old water in the water tank regularly. Because water is stored for too long, the water quality will change. So don't put water in the water tank or sink when you don't use it for a long time.
3. When the humidifier is put away, please clean the wet part and dry it, preferably in a ventilated place and put it in the box.
4. Three points should be paid attention to when cleaning the transducer: First, disconnect the power supply and operate. Secondly, it should be cleaned with a special cleaning agent from Du Ya. When cleaning, drop 5- 10 drops of cleaning liquid on the sensor surface. Of course, it should be increased or decreased according to the scale degree until the scale is removed. Be careful not to use hard tools to forcibly remove the scale, so as not to scratch the sensor. Finally: after cleaning, rinse the water tank with clean water. When cleaning, do not pour or splash water into the base to avoid short circuit and damage to electronic components.
5, water level float switch, also should pay attention to check in the process of use, if the float scaling, weight increase, will also lose the function of waterless self-stop, affect the normal work of the machine.
7. The air duct is clean. All humidifiers have pneumatic devices. With this device, there is an air inlet and an air outlet. Long-term use of the air inlet will also lead to dust blockage, which will lead to poor air intake and directly affect the diffusion of water mist. The air inlet and air outlet of the machine should be cleaned regularly. Humidifier should not be overused. Many people use humidifiers all night in dry spaces or seasons. Health experts say that high indoor humidity can easily lead to diseases such as influenza, asthma and bronchitis in the elderly.
Generally, when the humidity is 40% RH-60% RH, people feel most comfortable and do not affect their health. When the air humidity is 55%RH, it is difficult for bacteria to spread, but if the air humidity is higher than 65%RH, it will make human respiratory system and mucosa uncomfortable and reduce immunity. On the other hand, if the air humidity is lower than 20%RH, the indoor inhalable particles will increase, and people will easily catch a cold. Therefore, using a humidifier with automatic constant humidity function can effectively avoid the problem of excessive or insufficient humidity. Families who use humidifiers for a long time should be equipped with hygrometers to keep the indoor humidity between 45-55%.
In order to maintain the most suitable humidification amount of humidifier, it is necessary to consider the specific situation of the room. A room of 20 square meters is suitable for using a humidifier with a humidification amount of more than 270ML/H, and a room of 40 to 50 square meters should choose a product with a humidification amount of 540 ml/h.
Humidifier should also be changed every day, preferably once a week, to prevent microorganisms in water from spreading into the air. Among them, it is best to use special humidifier cleaning solution or white vinegar to clean the ultrasonic humidifier regularly, and the water used should be below 40℃, and other kinds of chemicals should not be added.
As for the pure humidifier, only the evaporator and filter screen need to be replaced once every one or two years.
A misunderstanding of humidifiers is that many consumers think that it is good to have "white fog" when humidifying. In fact, the "white fog" produced by humidifier is the result of spraying minerals in water with the fog. These droplets containing minerals have strong adsorption capacity. If the white fog of the humidifier is too heavy, these droplets sprayed indoors will absorb indoor bacteria, viruses or toxic substances left indoors during decoration. If the user inhales too many droplets of this complex composition, it is easy to cause respiratory discomfort, and in severe cases, it will suffer from related diseases. Therefore, "fog-free" humidifier is a wise choice.
The placement of humidifiers is also particular. In order to ensure its normal use, it is best to put it on a stable plane with a height of 0.5- 1.5 meters, away from heat sources, corrosive substances and furniture, and avoid direct sunlight. Some experts reminded that it is best to keep the humidifier at a distance of about 1 m from all household appliances and furniture.
At the same time, the humidifier should keep a distance of about 1 m from all household appliances and furniture. In particular, TV sets and air conditioners should be far away from the location of humidifiers to prevent household appliances from being affected by moisture.
Dryness is the enemy of health. Drying will not only make the human body lose a lot of water, but also cause skin tension, dry mouth, cleft lip and excessive internal heat, and also cause respiratory diseases such as influenza and pharyngitis. Indoor air drying will also do harm to furniture, floors, household appliances and other utensils, shortening the service life. Even in the south, the indoor air humidity is only lower than 40%RH in autumn and winter without rain or after using air conditioning, which is obviously lower than the normal indoor humidity of 40%~70%RH. Add a humidifier to free the family and all kinds of things at home from dryness and enjoy the "warm and humid" autumn and winter.
Ultrasonic humidifier: Based on the principle of ultrasonic high-frequency oscillation, water is atomized into ultrafine particles of 1~5μm, and the water mist is diffused into the air by pneumatic device to achieve the purpose of humidifying the air evenly. Ultrasonic humidifier has the advantages of high humidification intensity, uniform humidification, high humidification efficiency, power saving, long service life and so on, and has been very popular. But the disadvantage of ultrasonic humidifier is also obvious, that is, it has certain requirements for water quality. This humidifier can not only humidify the air daily, but also beautify the bath surface.
Electric heating humidifier: water is heated to the boiling point by heating elements, and the generated steam is released into the air. There is no requirement for water quality, and the disadvantages are high energy consumption, inability to dry burn, low safety factor and easy scaling on the heater.
Pure humidifier: By molecular sieve evaporation technology, calcium and magnesium ions in water are removed, and the problem of "white powder" caused by poor water quality is completely solved. The air is washed by the water curtain, humidified and purified at the same time, and then the wet and clean air is sent into the room by the pneumatic device, thus improving the environmental humidity. The new generation pure humidifier adopts fuzzy control, automatically adjusts the humidification amount with the change of temperature and humidity, and uses the principle of dynamic balance to control the relative humidity of the environment between 45% and 65% RH, which is most suitable for human body. When the indoor relative humidity is higher than 50%RH, the humidifier will automatically reduce the amount of humidification, so that the environment is always in a constant humidity state and is not limited by water quality. This humidifier can also filter air and kill bacteria, which not only makes the humidification more pure, but also washes the air with pure water, effectively eliminating air pollution, promoting indoor air circulation, ensuring human health to a greater extent and reducing the probability of respiratory tract infection.
