AI Technical Summary
Existing humidifying fan heaters suffer from structural issues where the air and mist outlets are separate components, leading to assembly difficulties, noise, and potential water mist inhalation by the fan, which can cause rust and health risks due to bacterial growth.
The humidifying heater integrates the air and mist outlets on a single cover body, incorporates a filter element to prevent mist inhalation, and uses an axial flow fan with a rear air inlet to ensure mist is blown into the environment rather than the fan, while a sealing sleeve maintains structural integrity.
This design enhances assembly convenience, reduces noise, prevents fan rust, and improves air quality by minimizing mist inhalation, thereby ensuring effective humidification without health hazards.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of small household appliances, in particular to a humidifying warm air machine. Background Art
[0002] With the improvement of the quality of life, people have higher and higher requirements for the comfort of indoor environment. As a household appliance that combines humidification and air supply functions, humidifying fan heaters are favored by consumers. However, there are still some problems that need to be solved in the design and use of existing humidifying fan heaters.
[0003] The humidifying heaters currently on the market are mainly composed of two parts: a fan device and a humidifying device. The fan device is responsible for generating wind flow, while the humidifying device releases water molecules into the air by spraying or evaporating, thereby achieving a humidifying effect. However, this design has many defects, such as the air outlet of the fan device and the mist outlet of the humidifying device are made of different parts, which are not convenient in the processing and product assembly of the two parts. Moreover, since they are the positions of air outlet and mist outlet, if they are not firmly fixed, the two parts will collide with each other and produce noise. For example, the water mist sprayed by the humidifying device is often directly inhaled by the fan device and blown out with the wind flow. This design method has the following problems: First, the fan device inhales water mist for a long time, which easily causes its internal parts to become damp and rusty, thereby affecting the normal use and life of the fan. Secondly, a humid environment is prone to breed bacteria and other microorganisms, posing a potential threat to the health of users. Especially in a closed indoor environment, these microorganisms may multiply and spread rapidly, having a negative impact on air quality. Utility Model Content
