Detailed Description

The utility model is further elucidated with reference to the drawing.

Referring to fig. 1 and 2, an embodiment of the present invention is a fan blade structure for an evaporative humidifier, including a rotating shaft 1, and a plurality of blades 2 are provided in a radial direction of the rotating shaft 1, and more importantly, the plurality of blades 2 are all centered on the rotating shaft 1, and as shown in the figure, are in an arc-shaped divergence shape along the radial direction of the rotating shaft 1, as shown in fig. 3 and 4, the plurality of blades 2 are also all inclined along an axial direction of the rotating shaft 1, and gaps between two adjacent blades 2 are equal, so as to ensure that when the rotating shaft 1 drives the plurality of blades 2 to rotate, the entire fan has stability, and reduce vibration. And based on the technical purpose of reducing the vibration, the radians of each fan blade 2 can be set to be equal, and the inclinations of each fan blade 2 can also be set to be equal. For the specific radial radian and axial inclination of the fan blade 2, those skilled in the art can design the fan blade arbitrarily according to the actual air intake requirement, and details are not described in this embodiment.

In the embodiment, the fan blade 2 of the fan is designed to be curved along the radial direction of the rotating shaft in an arc shape and inclined along the axial direction of the rotating shaft, so that the air intake of the fan at a unit rotating speed can be effectively increased, and the fan can obtain a larger air intake at a low rotating speed when the humidifier is used, so that the noise of the humidifier during use can be reduced while the humidification amount is increased, and the use experience of the evaporative humidifier can be further improved.

Still referring to fig. 1, according to another embodiment of the present invention, the fan blade structure is integrated into a fan, the fan can be designed into an integral structure, so that when the fan blade structure is integrated, firstly, the rotating shaft 1 is movably arranged in the middle of the fan bracket body 3, the middle part of the fan bracket body 3 is provided with an annular space, the fan blade 2 is arranged in the environment space, and the upper part and the lower part of the fan blade 2 respectively keep a clearance with the upper part and the lower part of the fan bracket body 3 so as to avoid the interference of the fan bracket body 3 to the fan blade 2, through the integrated structure, the rotating shaft 1 can drive the fan blades 2 to rotate in the annular space in the middle of the fan bracket body 3, when the fan blade 2 rotates, the air flow enters from the hollow part at the lower part of the fan bracket body 3 and is blown out from the annular space, and when the fan blade 2 rotates continuously, continuous air flow can be formed. In the embodiment, in order to facilitate the power connection between the fan and the motor, based on the general structure of the vertically-arranged humidifier, a power connection end 11 may be designed at the upper part of the rotating shaft 1, and the power connection end 11 is used for power connection with the output end of the motor; and the power connection end 11 is arranged at the upper part of the fan bracket body 3 so as to be conveniently matched with a motor arranged in the longitudinally-arranged humidifier.

The fan blades of the fan are designed to be in a structure of combining an arc shape and an inclined plane, so that the air inlet volume of the fan is larger in the same unit time and the same unit rotating speed, the rotating speed of the fan can be reduced under the condition of ensuring large air volume, the noise is further reduced, the silent operation of the evaporative humidifier is facilitated, the fan blade can be used as an airflow fan in another patent (publication No. CN 111912069A) of the applicant, and the user experience of longitudinal humidifier products is effectively improved.
