[0035] When the device is in a working state, the second supporting plate 32 rotates around the first supporting plate 31 at this time, and the U-shaped connecting rod 36 is located at the bottom end of the first housing 1. When the second supporting plate 32 rotates, the clamping plate 321 can clamp the U-shaped connecting rod 36. At this time, the rotating rod 33 is inserted into the inside of the supporting hole 322, and then the second supporting plate 32 is placed on the ground. The rotating rod 33 and the second supporting plate 32 can support the weight of the whole device, so that it can be placed vertically on the ground. The clamping plate 321 clamps the U-shaped connecting rod 36, which can prevent the first housing 1 and the second housing 2 from shaking left and right, thereby improving the stability. When it is needed to be stored, only the pressing rod 14 needs to be pressed. The pressing rod 14 can release the connecting opening 211, so that the second housing 2 can be rotated at this time. When the second housing 2 is stored in the first housing 1, the U-shaped connecting rod 36 will rotate to the upper side of the first housing 1, the second supporting plate 32 will rotate to be attached to the first supporting plate 31, and the second supporting plate 32 is clamped by the motor 4. At this time, the device is stored, and the connecting opening 211 is clamped by the fixed clamping plate 13 on the other side.

[0036] When the device needs to be reopened, only need to press the fixed clamping plate 13 first release the connecting port 211, then hold the U-shaped connecting rod 36 is rotated, the U-shaped connecting rod 36 can drive the second shell 2 is rotated to the outside of the first shell 1, the connecting port 211 will be one side of the fixed clamping plate 13 clamping, at this time the arc-shaped rod 22 loses the pushing effect of the cleaning component 6, the cleaning component 6 will return to the original position under the action of the first spring 11, facilitate rework.

[0037] Working principle: when the device needs to be stored, at this time the motor 4 is closed, and the connecting plate 5 and the fan blade 51 lose power and stop rotating, under the action of gravity, the fan blade 51 will naturally droop, at this time the second shell 2 is rotated to enter the inside of the first shell 1, when the second shell 2 is rotated to enter the inside of the first shell 1, at this time the cleaning component 6 will be driven to clean the surface of the fan blade 51, prevent the influence on the next use;

[0038] When the device needs to be reopened, only need to press the fixed clamping plate 13 first release the connecting port 211, then hold the U-shaped connecting rod 36 is rotated, the U-shaped connecting rod 36 can drive the second shell 2 is rotated to the outside of the first shell 1, the connecting port 211 will be one side of the fixed clamping plate 13 clamping, at this time the arc-shaped rod 22 loses the pushing effect of the cleaning component 6, the cleaning component 6 will return to the original position under the action of the first spring 11, facilitate rework.

[0039] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
