Description

Indoor air humidifier

Technical Field

The invention relates to indoor air humidity adjustment, in particular to an indoor air humidifier, and belongs to the technical field of household appliances and new materials.

Background

Air humidity has a significant impact on the health of the human body. In autumn, winter, early spring, northern China and other areas, the indoor environment is often very dry, so people living and working in the indoor environment feel uncomfortable, and therefore an air humidifier is needed to increase the humidity of indoor air. Currently, air humidifiers used indoors mainly include ultrasonic humidifiers, direct evaporation type humidifiers, and thermal evaporation type humidifiers. The ultrasonic humidifier is based on the principle that water is atomized by ultrasonic vibration, distilled water or purified water is required to be used, otherwise calcium-magnesium white powder is easily generated, the white powder can be dispersed in the air to hurt the respiratory system of a human body, and the white powder is difficult to clean when falling on objects such as furniture, a refrigerator and a television. The direct evaporation type humidifier generally uses a fan to blow an evaporation core which absorbs water and is wet, so as to accelerate the evaporation of water, tap water can be used as a water source, obvious atomized water vapor is not generated, but the direct evaporation type humidifier has the problems of large noise and low humidification amount. The working principle of the heat evaporation type humidifier, also called as an electric heating type humidifier, is that water is heated to a boiling point in a heating body to generate steam, and the steam is blown out by a fan, so that the problems of high energy consumption, no dry burning, low safety coefficient, easy scale generation on a heater and the like exist. In addition, the height of the humidifier is fixed, and when the humidifier is directly placed on the ground, the humidifier is low in height and occupies space when placed on a table, so that the height is inconvenient to adjust. Moreover, the generated mist or vapor easily makes the floor tile surface or the floor surface near the humidifier moist and dirty, and is difficult to clean. In addition, the existing humidifier products are mostly shown in the form of household appliance industrial products, and are lack of artistic interest and aesthetic feeling.
