Description

Technical Field

[0001] The utility model relates to the technical field of atomizing fans, in particular to a double air duct structure of an atomizing fan. Background Art

[0002] The dual duct structure of industrial fans refers to the fresh air duct and the exhaust duct, which work together to achieve efficient air flow and ventilation effects. Usually, atomizing fans can only dissipate heat and cool in a single direction.

[0003] According to the “Atomizing Fan with Dual Air Duct Structure” of Chinese Patent Publication No. CN206018894U, what is described is mainly the simultaneous provision of the natural air supply channel and the forced air supply channel that can independently supply air. The natural air supply channel can further provide more conveying airflow for blowing atomized steam on the basis of the forced air supply channel. Through experiments, it is found that, while basically maintaining the original energy consumption, the amount of atomized steam blown out when the natural air supply channel and the forced air supply channel work at the same time is approximately 1.5 times the amount of atomized steam blown out when the forced air supply channel works alone. In this way, the addition of the natural air supply channel can greatly increase the amount of mist output. In this process, the atomizing fan can only cool and dissipate heat in a single direction, and the purification surface is small.

[0004] Therefore, a dual-air duct structure of an atomizing fan is proposed to solve the problem that during this process, the atomizing fan can only cool and dissipate heat in a single direction, resulting in a small purification surface. Utility Model Content

The ultrasonic atomizer 12 uses high-frequency vibration to break water molecules into tiny water mist particles, thereby achieving an atomization effect. The bottom end of the ultrasonic atomizer 12 is connected to a water pump through a hose 13. The water pump guides water through the hose 13. The water pump is fixedly connected to the air guide frame 2. A groove is provided on the fixed plate 1 and the fixed plate 1 is fixedly connected to a drive motor on one side of the groove. A bidirectional screw 6 is fixedly connected to the output end of the drive motor.
