Description

Technical Field

[0001] This utility model relates to the technical field of cleaning devices, specifically to a device for cleaning fan ducts. Background Technology

[0002] The existing air supply ducts of fans are relatively difficult to clean. Over time, the dust accumulated inside can lead to air pollution, easily breed bacteria, and affect the air volume. Therefore, it is necessary to use a duct cleaning device to clean the dust and impurities accumulated inside.

[0003] However, existing fan duct cleaning devices are difficult to adjust according to the inner diameter of the duct during use, and only have a simple cleaning function. During the cleaning process, dust inside the duct is prone to floating and filling, so multiple cleaning operations are required. The practicality and operability need to be improved.

[0004] Therefore, this utility model proposes a device for cleaning fan ducts. Utility Model Content

Multiple sets of the cleaning fan are arranged horizontally along the surface of the expansion plate and the side connection layer, and the cleaning fan is distributed in a clockwise spiral.

The connecting supports are movably connected to the inner end of the first connecting arm via a shaft, while the outer end of the first connecting arm is movably connected to the top surface of the inner side of the expansion plate via a shaft.

[0013] Furthermore, the second connecting arms are arranged in pairs, with a total of three sets corresponding to the expansion plate. Both ends of the second connecting arms are movably connected to the inner bottom of the expansion plate and the surface of the mounting cylinder via shafts.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0026] See Figure 1-3 As shown, a device for cleaning fan ducts includes an operating lever 1. A dust collection component 2 and a mounting cylinder 3 are sequentially fixedly connected to the top of the operating lever 1. An internal drive mechanism 8 is embedded inside the mounting cylinder 3. A drive rod 9 is connected to the top of the internal drive mechanism 8. A connector 10 is fixedly connected to the top of the drive rod 9. A first connecting arm 11 is movably connected to the outer end of the connector 10. An expansion plate 4 is movably connected to the outer end of the first connecting arm 11. A second connecting arm 12 is movably connected to the inner side of the expansion plate 4. The inner end of the second connecting arm 12 is also movably connected to the mounting cylinder 3. A side connecting layer 5 and an upper connecting layer 7 are fixedly connected to the side and top of the expansion plate 4, respectively. A cleaning fan 6 is fixedly connected to the surface of both the expansion plate 4 and the side connecting layer 5. A dust collection pipe 13 is connected to the top of the dust collection component 2. The dust collection pipe 13 is also connected to the cleaning fan 6.

[0027] In this embodiment of the utility model, the dust collection component 2 includes a set of cylindrical shells and a built-in adsorption mechanism. The cylindrical shells are connected to the operating rod 1, and the adsorption mechanism is connected to the dust collection pipe 13. The expansion plate 4 is an arc-shaped plate with three sets evenly distributed. It is hollow inside and has multiple sets of strip-shaped dust collection ports on its surface. The cleaning fan 6 is a hard rubber fan, which is rectangular and vertically arranged. Multiple sets of cleaning fans are arranged horizontally along the surface of the expansion plate 4 and the side connecting layer 5. The cleaning fan 6 is distributed in a clockwise spiral. The dust collection component 2 and the dust collection pipe 13 achieve the effect of adsorbing dust particles in the external pipe. The expansion plate 4, in conjunction with the dust collection ports on its surface, achieves the effect of embedding into the external pipe to complete the dust collection and cleaning. The cleaning fan 6 achieves the effect of cleaning the inner wall of the external pipe.

[0028] When cleaning the inner wall of the external pipe, the expanded expansion plate 4, together with the cleaning fan 6 on its surface, comes into contact with the inner wall of the external pipe. Then, the operator rotates the device, causing the cleaning fan 6 to scrape and clean the dust and impurities on the inner wall of the external pipe. During the cleaning process, the dust collection component 2 is activated, generating negative pressure adsorption inside the external pipe. Fly dust and impurities are adsorbed and collected into the operating rod 1 through the dust collection port on the surface of the expansion plate 4 under the action of the dust collection pipe 13. This completes both the cleaning of the inner wall of the pipe and the dust collection cleaning.

[0029] The outer end of the connector 10 is provided with three sets of protruding connecting supports at equal intervals. The connecting supports are movably connected to the inner end of the first connecting arm 11 via a shaft. The outer end of the first connecting arm 11 is movably connected to the inner top surface of the expansion plate 4 via a shaft. The second connecting arms 12 are arranged in pairs, with a total of three sets corresponding to the expansion plate 4. Both ends of the second connecting arms 12 are movably connected to the inner bottom of the expansion plate 4 and the surface of the mounting cylinder 3 via shafts. The connector 10 achieves the effect of driving the first connecting arm 11 to move and adjust. The first connecting arm 11 achieves the effect of driving the expansion plate 4 to expand inward and outward. The second connecting arms 12 achieve the effect of assisting the expansion plate 4 to expand inward and outward.

[0030] When cleaning the inner wall of the external pipe, the user can adjust the expansion range of the expansion plate 4 according to the inner diameter of the pipe. The inner drive mechanism 8 is activated, and under the lifting action of the drive rod 9, it drives the first connecting arm 11 in conjunction with the connector 10. The first connecting arm 11 drives the expansion plate 4 to adjust inward and outward outside the mounting cylinder 3. The second connecting arm 12 adaptively adjusts the angle as the expansion plate 4 expands inward and outward. After adjustment, the expansion plate 4 can ensure that the cleaning fan 6 connected to its surface is in contact with the inner wall of the pipe, thereby ensuring the cleaning effect.

[0031] Both the upper connecting layer 7 and the side connecting layer 5 are rubber corrugated layers. The upper connecting layer 7 is a circular corrugated layer, and the side connecting layer 5 is a rectangular corrugated layer. There are three sets of side connecting layers 5, located between the expansion plates 4. The upper connecting layer 7 and the side connecting layer 5 achieve the effect of sealing the top and side positions of the expansion plate 4, and can also adaptively extend and adjust according to the internal and external expansion adjustment of the expansion plate 4.

[0032] In this device, the operating lever 1 is a hollow lever body. A filter-type air intake window for the dust collection component 2 can be opened on its bottom side, and a plug-type cleaning window can also be opened to facilitate cleaning the inside of the operating lever 1. Dust and impurities adsorbed and cleaned by the dust collection component 2 can be cleaned through the cleaning window.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
