When the cleaning belt 32 needs to be cleaned, the supporting frame 31 is separated from the housing 10, at this time, the first transmission shaft 33 rotates around the housing 10, the supporting frame 31 rotates around the first transmission shaft 33, so that the second transmission shaft 33 in the cleaning assembly 30 extends out of the housing 10, and the second transmission shaft 33 drives a part of the cleaning belt 32 to extend out of the housing 10, thereby cleaning the cleaning belt 32. The cleaning belt 32 of the cleaner can be at least partially separated from the casing 10 of the cleaner, so that the cleaning belt 32 is convenient to clean, and the use experience of a user is improved.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
