[0003] At present, the existing spray axial flow fans adopt the principle of secondary division for water supply atomization. However, the water in the fan hub has a significant impact on the dynamic balance of the fan. This kind of fan not only has a small total water supply, but also The water also increases the additional load of the motor, making the service life lower
[0004] Most of the current spray axial flow fans use a separate impeller for spraying, which makes the water mist diffuse slowly and the water mist spread unevenly

Embodiment Construction
[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0041] see Figure 1-Figure 13 The present invention provides a technical solution: a spray axial flow fan with water-saving and energy-saving functions. The front wind wheel and the rear wind wheel are respectively arranged on the sides, and the water mist fan wheel 2 forms water mist through vibration, and the rear wind wheel impacts the moisture on the water mist fan wheel through the air flow.
[0042] A support plate 101 and a power part are installed in...

The invention discloses a spraying axial flow fan with water-saving and energy-saving functions, and belongs to the technical field of ventilation. The spraying axial flow fan comprises a ventilation cylinder, wherein a water mist fan wheel is arranged in the ventilation cylinder; a front wind wheel and a rear wind wheel are arranged on the two sides of the water mist fan wheel respectively; the water mist fan wheel forms water mist through vibration; and the rear wind wheel impacts water on the water mist fan wheel through airflow. The rear wind wheel rotates at a high speed behind the upper water mist fan wheel, the rotating speed of the rear wind wheel is larger than the rotating speed of the front wind wheel, a high-pressure area is formed behind the water mist fan wheel, high-pressure airflow impacts water on the water mist fan wheel, meanwhile, water can be vibrated by components in the water mist fan wheel through vibration, water mist is formed when the water leaves the water mist fan wheel through vibration, the humidity of high-pressure airflow is increased after the high-pressure airflow penetrates through the water mist fan wheel, water leaves the water mist fan wheel under the action of vibration energy and wind energy, and water mist is combined with the high-pressure airflow so as to participate in the ventilation link under the action of the front wind wheel.
Description
technical field [0001] The invention relates to the technical field of ventilation, in particular to a spray axial flow fan with water-saving and energy-saving functions. Background technique [0002] Axial flow fans, because the gas flows parallel to the fan shaft, are called "axial flow", and their uses are very wide, such as electric fans, air conditioner fans, etc., are fans that operate in axial flow. [0003] At present, the existing spray axial flow fans adopt the principle of secondary division for water supply atomization. However, the water in the fan hub has a significant impact on the dynamic balance of the fan. This kind of fan not only has a small total water supply, but also The water also increases the additional load of the motor, making the service life lower. [0004] Most of the current spraying axial flow fans use a separate impeller for spraying, which makes the water mist diffuse slowly and the water mist spread unevenly. Contents of the invention ...
