Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, the fan cleaning device includes a bracket 1, a driving member 2, and a cleaning structure 3, the bracket 1 is fixedly connected with the cleaning structure 3, the driving member 2 is slidably fitted with a spiral slideway 11 on the bracket 1, in order to calculate and control the rotation angle of the cleaning structure 3, it is recommended that the cleaning structure 3 and the driving member 2 are symmetrically arranged with respect to the rotation axis of the bracket 1, and when the fan cleaning device is used, the displacement of the bracket 1 along the rotation axis direction needs to be limited;

the fan cleaning device is characterized in that the support 1 is a solid or hollow cylindrical body, the spiral slideway 11 which is spiral along the surface of the support 1 is arranged on the support 1, the size of the spiral slideway 11 meets the requirement of the rotation angle of the support 1, the support 1 is in rotating fit with a structure which needs to be provided with the fan cleaning device, in order to reduce the friction force when the support 1 rotates, the support shafts 12 which are smaller than the support 1 in size are recommended to be arranged at the two ends of the support 1, the support shafts 12 are in rotating fit with the structure which needs to be provided with the fan cleaning device, correspondingly, the fan cleaning device is recommended to be matched with bearings which are matched with the support 1 or the support shafts 12, so that the support 1;

when the bracket 1 is a solid body, the driving part 2 comprises a driving head 21 and a driving rod 22, and the driving head 21 and the driving rod 22 are fixedly connected; as shown in fig. 3, when the support 1 is a hollow body, the driving member 2 may further include a limiting block 23 in addition to the driving head 21 and the driving rod 22, the limiting block 23 is located inside the support 1, the limiting block 23 is used to limit the displacement of the driving rod 22 along the radial direction of the support, so that the driving rod 22 is more stable and is not easy to be separated from the spiral slideway 11 when moving in the spiral slideway 11, the limiting block 23 may also be replaced by a nut, and the driving rod 22 is respectively connected to the limiting block 23 located inside the support 1 and the driving head 21 located outside the support 1; the driving rod 22 extends into the spiral slideway 11, and a rod body of the driving rod 22 is contacted with the spiral slideway 11;

when the support 1 is required to rotate, firstly, the displacement of the support 1 along the rotation axis direction is limited, so that the driving rod 22 is driven by the driving head 21 to linearly move along the rotation axis direction of the support 1 in the spiral slideway 11, the support 1 starts to rotate under the matching action of the driving rod 22 and the spiral slideway 11, and the cleaning structure 3 is driven to rotate, wherein the driving head 21 can be a handle or a slide block which is driven in a manual mode, and can also be an electric driving mechanism which can perform reciprocating linear motion, such as a linear motor, a crank connecting rod and the like;

the cleaning structure 3 can be made of flexible materials such as rubber, sponge, brushes and the like, and considering that the fan cleaning device cleans fan blades when the fan rotates, the brushes with small rotating resistance and good cleaning effect on the fan are preferably selected;

as shown in fig. 4, 5 and 6, the fan cleaning device is installed at the fan in the air purifier, the air purifier only needs to provide a structure for limiting the displacement of the support 1 along the self axial direction, the rotation of the support 1 is not limited, the position of the fan cleaning device is suitable for the maximum contact area of the cleaning structure 3 and the fan blades, the rotation range of the cleaning structure 3 is 90 degrees, namely when the fan cleaning device is used for cleaning the fan blades, the cleaning structure 3 is perpendicular to the wall surface of the protective cover of the fan and is contacted with the fan blades, and when the fan blades are not cleaned by the fan cleaning device, the cleaning structure 3 is tightly attached to the wall surface of the protective cover of the fan;

when the driving rod 22 adopts a manual driving mode, a long-strip through hole is formed in a position, corresponding to the driving piece 2, on a fan protective cover of the air purifier, the driving head 21 is located in the long-strip through hole, the length of the long-strip through hole meets the requirement of the moving stroke of the driving head 21, when the driving head 21 is located at two ends of the long-strip through hole, the cleaning structure 3 is in contact with or separated from the fan, the long-strip through hole is used for limiting and guiding the driving head 21, and correspondingly, sliding grooves in sliding fit with the wall surfaces of the through holes are required to be arranged on two surfaces, in contact with the long-strip; when the driving rod 22 adopts an electric driving mechanism, the driving head 21 is directly installed in the machine body;

when needing to clear up fan blade, only need drive actuating lever 22 to spiral slideway 11 one end for clean structure 3 and fan blade contact, then open air purifier make the fan rotatory can, the clearance back of finishing, close air purifier, treat the fan stall back, drive actuating lever 22 to spiral slideway 11's the other end, thereby make clean structure 3 and hug closely the wall of air purifier organism and break away from with the fan, finish cleaning the fan.
