Description

Technical Field

[0001] The utility model relates to the technical field of humidifiers, and particularly relates to an upper-watering mist-free humidifier with a multi-layer filtering structure at the top. Background Art

[0002] The principle of a mist-free humidifier is to blow the moisture of a wet curtain into the external environment through air flow to achieve humidification. For this kind of mist-free humidifier, the water in the water tank is pumped to the top of the wet curtain by a water pump for watering. When the water absorption of the wet curtain or filter element is saturated, the excess water will flow back to the bottom water tank, and the wet curtain is watered cyclically by the water pump. Among them, the water tank is generally arranged at the top or bottom of the humidifier, and it is necessary to take out or draw out the bottom water tank, or open the top water tank to add water. In order to facilitate direct watering from above the humidifier into the bottom water tank without disassembling the casing or taking out the water tank, an upper-watering mist-free humidifier that can be directly watered from above has been introduced on the market. For example, a floor-standing mist-free humidifier with a hidden watering structure disclosed in the patent number CN219415058U. However, this kind of mist-free humidifier structure lacks the design consideration of water addition filtration, so further improvement is needed. Content of the Utility Model
