Description

Technical Field

[0001] The utility model relates to a fan blade structure on a humidifier, belonging to the technical field of humidifier equipment. Background Art

[0002] The fan blades on the existing humidifier fan cannot be disassembled. After long-term use, there is a lot of dirt on the fan blades, which is difficult to clean, resulting in poor air quality after humidification and even the appearance of odor.

[0003] In addition, when adding water to the humidifier, water may splash onto the fan blades, and the fan blades may throw the water out of the body when turning, causing water splashing; or during the humidification process, water vapor may condense on the fan blades, causing dynamic imbalance during the rotation of the fan, accelerating fan wear and reducing the service life of the humidifier.

[0004] Therefore, it is necessary to conduct in-depth research on the existing humidifier fan blade structure to solve the above problems. Utility Model Content

[0005] In order to overcome the above problems, the inventors conducted in-depth research and proposed a fan blade structure for a humidifier, wherein the fan blade 1 is detachably arranged on the fan shaft of the humidifier.

[0006] In a preferred embodiment, a fan blade cover 2 is provided at the connection position between the fan blade 1 and the humidifier fan shaft for fixing the fan blade 1.

[0007] In a preferred embodiment, a drain port 3 is provided on the fan blade 1 and the fan blade cover 2 .

[0008] In a preferred embodiment, an anti-slip groove 21 is provided on the edge of the blade cover 2 .

[0009] In a preferred embodiment, the front end of the fan blade cover 2 is an arc-shaped protrusion.

[0010] In a preferred embodiment, a protective mesh cover is provided below the fan blade 1 .

[0011] The utility model also discloses a humidifier having the fan blade structure as described in one of the above embodiments.

[0012] The beneficial effects of the utility model include:

[0013] (1) The fan blades inside the humidifier can be quickly disassembled for easy cleaning and to maintain indoor air quality;

[0014] (2) The rotation stability of the fan is improved and the service life of the fan is increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be described in further detail below through the accompanying drawings and examples, through which the features and advantages of the present invention will become more clearly understood.

[0025] The word "exemplary" is used exclusively herein to mean "serving as an example, example, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0026] According to the fan blade structure of a humidifier provided by the present invention, the fan blade 1 is detachably arranged on the fan shaft of the humidifier.

[0027] In a preferred embodiment, Figure 1 As shown, a fan blade cover 2 is provided at the connection position between the fan blade 1 and the humidifier fan shaft for fixing the fan blade 1.

[0028] During the humidification process, water vapor may condense on the fan blades, or when adding water to the humidifier, water may splash onto the fan blades, causing dynamic imbalance during the rotation of the fan, accelerating fan wear, and reducing the practical life of the humidifier.

[0029] In a preferred embodiment, a drain port 3 is provided on the fan blade 1 and the fan blade cover 2. Figure 1-3The water on the fan blades is drained through the drain port to avoid dynamic imbalance during the fan rotation.

[0030] Preferably, there are multiple drain outlets 3, which are evenly arranged around the circumference of the fan shaft.

[0031] In a preferred embodiment, an anti-slip groove 21 is provided on the edge of the blade cover 2 to facilitate the user to screw the blade cover 2 .

[0032] There are multiple anti-slip grooves 21 circumferentially arranged on the edge of the fan blade cover 2.

[0033] In a preferred embodiment, the front end of the fan blade cover 2 is an arc-shaped protrusion, which plays a guiding role and reduces the wind resistance of the fan blade cover 2.

[0034] More preferably, if Figure 4 As shown, the protruding angle α of the front end of the fan blade cover 2 is 20-40°, which can achieve the best diversion effect.

[0035] In a preferred embodiment, reinforcing ribs are provided on the inner side of the blade cover 2 to increase the strength of the blade cover 2 .

[0036] Further preferably, the reinforcing ribs are provided in plurality, and the plurality of reinforcing ribs are arranged to diverge from the center of the blade cover to the circumference of the blade cover, such as Figure 3 shown.

[0037] In a preferred embodiment, the fan blade cover 2 is connected to the fan shaft through threads. More preferably, the tightening direction of the fan blade cover 2 is opposite to the rotation direction of the fan to prevent the fan blade cover 2 from loosening due to the rotation of the fan.

[0038] In a preferred embodiment, a protective mesh is provided below the fan blades 1 to prevent the fan blades 1 from falling off the fan shaft and flying out due to the fan blade cover 2 not being tightly closed. In the present invention, the specific structure of the protective mesh is not limited, and those skilled in the art can freely configure it according to actual needs, as long as it can protect the fan blades.

[0039] According to a preferred embodiment of the present invention, the fan is an axial flow fan, which has many advantages such as simple installation and low cost.

[0040] The utility model also discloses a humidifier having the fan blade structure as described above.

[0041] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front," and "rear" and the like, indicating positions or relationships, are based on the positions or relationships in the operating state of the utility model and are intended solely to facilitate and simplify the description of the utility model.
