Abstract
Description
[Technical Field]
[0001] This utility model mainly relates to a fan blade structure that can filter air. [Background Technology]
[0002] With increasing environmental pollution, indoor air quality has become a major concern. Traditional air purifying fans typically employ a separate design of "filtration system + air delivery system," where air is first purified by a filter module before being propelled out by the fan blades. This air purification function is usually added as a separate module to the bottom or rear of these fans, creating a complex internal structure. Therefore, to simplify the product structure and reduce energy consumption and noise, we propose a new structural design. [Utility Model Content]
[0003] To solve at least one of the above problems, this utility model proposes a new structural solution. The air-filtering fan blade structure adopts the following technical solution:
[0004] An air-filtering fan blade structure includes a fan motor, a fan blade mounted on the fan motor, and filter cotton; the inner end of the fan blade is connected to the fan motor, and the fan blade gradually tilts and bends from its inner end to its outer end, so that a height difference is formed on both sides of the fan blade.
[0005] The outer end of the fan blade has a cavity, and one side of the fan blade has a slot. The filter cotton is inserted into the cavity through the slot. Both the upper and lower ends of the cavity are equipped with mesh rails, and the filter cotton is located between the mesh rails.
[0006] Preferably, the mesh fence is composed of several metal strips that are connected to each other in a crisscross pattern, and the ends of the metal strips are fixed to the cavity wall.
[0007] Preferably, the thickness of the filter cotton is the same as the height of the cavity.
[0008] The beneficial effects of this utility model compared with the prior art are:
[0009] To simplify the product structure and reduce energy consumption and noise, this design directly hollows out the front end of the fan blade to form a cavity. Metal mesh railings are welded to both the top and bottom of the cavity, and only one side of the cavity has a slot for inserting filter cotton. The filter cotton and fan blade are detachable, allowing for frequent replacement, and the hollow design facilitates easy replacement. It boasts advantages such as simple structure, compact fit, and rational design; therefore, it is a product with superior technical and economic performance. [Attached Image Description]

Detailed Implementation Methods
[0012] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.
[0013] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0014] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0015] The preferred embodiment provided by this utility model is as follows: Figures 1-2 As shown, an air-filtering fan blade structure includes a fan motor 1, a fan blade 2 mounted on the fan motor 1, and a filter cotton 3; the inner end of the fan blade 2 is connected to the fan motor 1, and the fan blade 2 gradually tilts and bends from its inner end to its outer end, so that a height difference is formed on both sides of the fan blade 2, and the inner end of the fan blade is the end connected to the fan motor.
[0016] The outer end of the fan blade 2 has a cavity 21, and one side of the fan blade 2 has a slot 22. The filter cotton 3 is inserted into the cavity 21 through the slot 22. Both the upper and lower ends of the cavity 21 are provided with mesh bars 23, and the filter cotton 3 is located between the mesh bars 23. The fan blade 2 is driven by the fan motor 1. The rotating fan blade 2 drives the filter cotton 3 to rotate, so that the filter cotton 3 can adsorb air impurities and purify the air.
[0017] The mesh grille 23 is composed of several intersecting metal strips, the ends of which are welded and fixed to the wall of the cavity 21. Conventional iron strips are acceptable. The filter cotton 3 is a flexible material, better adaptable to the curved fan blades 2. The filter cotton 3 is fitted into the cavity 21 using an interlocking method. The thickness of the filter cotton 3 matches the height of the cavity 21 for a tight fit. To further improve the connection strength of the filter cotton, it can be fixed with adhesive or secured to the fan blades with screws.
[0018] To simplify the product structure and reduce energy consumption and noise, this design directly hollows out the front end of the fan blade 2 to form a cavity 21. Metal mesh railings 23 are welded to both the upper and lower ends of the cavity 21. The cavity 21 has a slot 22 on only one side for inserting the filter cotton 3. The filter cotton 3 and fan blade 2 are detachable, allowing for frequent replacement. The hollow design also facilitates replacement; the filter cotton can be pried out through the hollowed-out area. As the fan blade 2 rotates, the filter cotton 3 increases its adsorption range, effectively purifying the air by adsorbing and reducing impurities. In this structure, the filter cotton 3 is directly installed on the fan blade 2 and does not need to be added as a separate module to the bottom or rear of these fans, thus simplifying the overall structure, eliminating energy consumption and noise, and facilitating maintenance.
