Description

technical field [0001] The invention relates to the technical field of air humidifiers, in particular to an atomization and evaporation dual-mode humidifier. Background technique [0002] Among the household air humidifiers, the more common humidifiers are divided into two types: ultrasonic atomization humidifiers and evaporative humidifiers according to the different humidification principles. [0003] The ultrasonic atomizing humidifier mainly uses ultrasonic vibration to break up water masses to form mist to increase the humidity of the air. It has the advantages of good local humidification effect, no need for heating, no consumables, and energy saving. However, the volume and mass of water molecules produced by the ultrasonic atomization humidification method are relatively large, and cannot exist in the air for a long time, and the transportation distance is not far , the humidification space is not large, and it is easy to form condensation around the humidifier. ...

AI Technical Summary

Problems solved by technology

[0005]1) In order to improve the evaporation efficiency, the larger the specific surface area of ​​the evaporation filter is, the better it can absorb more water; The flux of the airflow passing through the evaporative filter element is also as large as possible, so that the airflow can convert more moisture in the evaporative filter element into water vapor; however, it is difficult to meet the above requirements in the limited internal space of the household humidifier, because the same volume of evaporation For the filter element, the larger the specific surface area, the poorer the air permeability, and if the fan power is increased in order to increase the air flow through the evaporative filter element, it will generate greater noise and power consumption

[0006]2) Due to the need to ensure the adsorption and replenishment of water during the use of the evaporation filter element, it is generally soaked in water in a large area in the prior art. The airflow cannot be passed through, which greatly reduces the effective evaporation area of ​​the evaporation filter element, and due to the large specific surface of the evaporation filter element, the fixed part soaked in water for a long time also provides a breeding ground for bacteria, which is very easy to breed bacteria and cause the discharged water vapor to generate smell

In the prior art, there is also a solution of spraying the water in the water tank onto the evaporation filter element through a multi-hole diversion method. This solution has the problems of uneven water distribution and the spraying process affects the air permeability of the evaporation filter element and reduces the evaporation efficiency.
