In addition, the main machine of the mite-killing dust collector can further comprise a water vapor component, and the water vapor component is used for spraying water vapor to the surface to be cleaned so as to sterilize and remove mites on the surface to be cleaned.

However, such a dust collector capable of spraying water vapor is liable to generate water stains on the surface to be cleaned when in use. This is because the steam component comprises a steam generator, the steam generator has low steam efficiency, so that water is not completely heated and vaporized to form steam, and incomplete vaporization easily causes the steam to condense to form water drops to stay on the surface to be cleaned, thereby easily causing water stains to remain on the surface to be cleaned.

In addition, the steam component still includes the steam shower nozzle, communicate through the pipeline between steam generator and the steam shower nozzle, after the water is heated to form steam in steam generator, the steam flows to the steam shower nozzle along the pipeline, then spout to the face of waiting to clean through the steam shower nozzle, because the pipeline has certain length, there is the heat loss when the steam flows along the pipeline, the steam can reduce when reaching the steam shower nozzle temperature, the easy condensation liquefaction becomes the water droplet and remains on waiting to clean the face, thereby it has the water stain to cause waiting to clean the face easily.
