[0048] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] A mite remover is a cleaning appliance that can kill bacteria. It usually comes with an ultraviolet sterilization lamp and a beater, and can be used to remove dust and mites from fabrics.

[0050] In humid environments, mites are particularly prone to grow on fabrics. While mite removers can remove dust and sterilize fabrics, if the fabrics remain in a humid environment, mites will quickly grow back.

[0051] In some existing technologies, mite removers utilize the hot air generated by the fan itself, which is blown directly onto the fabric through the exhaust vent to achieve a dehumidifying effect. However, since the exhaust vent is located on the fan, although there is some dehumidification effect, the concentrated exhaust from the exhaust vent results in low dehumidification efficiency.

[0052] Example 1

[0053] like Figure 7 As shown, a cleaning device includes: a bottom shell 5 and a cover plate 31. The cover plate 31 and the bottom shell 5 are fastened together to form an exhaust duct 3.
