Detailed Description Of The Invention

Although do not plan to limit the utilization of cleaning device as herein described and burnisher, it is believed that its purposes of summary will help to illustrate the present invention.

Drag in the operation in conventional wet so far, the mop user requires a detergent source, is administered on the surface to be cleaned by mophead.Early stage practice is that mophead is immersed in the outer liquid body source, for example in bucket, randomly twists out excess liquid, with enough power mophead is affacted the surface then and goes up the dirt of removal on it.Unfortunately, after using repeatedly, mophead self becomes dirty, unhygienic, ugly and has to and is removed and washs.In addition, hold soon in the bucket of dirty solution because the mop user is immersed mophead, traditional mop is easy to dirt and bacterium are deposited on the floor surface once more, and therefore the viewpoint from health is not to be best.

Modern times drag the instrument of washing to use disposable wipe or absorption pad, and it is fixed on the head that drags the instrument of washing separatably, and it can abandon and change after dirty easily.Even more modern instrument carries their detergent reservoir, thereby greatly strengthened their practicality and convenience.In use, liquid thereby helps a liquid delivery apparatus and is assigned on the surface to be cleaned.

That these instruments especially are convenient to remove the surface from floor surface and/or " gently " dirt self is not enough to from the obstinate dirt of floor surface removal yet expose.

As will understanding, a shampooing and/or scraping tool must be fixed on such instrument to promote the removal of obstinate dirt to a certain extent at once.In addition, washing and rubbing utensil must be pulled down sometimes so that its shampooing surface of rinsing or to its processing.In addition, it would be desirable that having a washing and rubbing utensil that can remove from moving tool up uses this washing and rubbing utensil so that the user can be independent of instrument, limit between user's hand and the dirty shampooing/scraped surface contacting simultaneously.As will be from the disclosure of this paper being seen, this mode with convenient and health be fixed-is used-dismantle-change order and causes several problems, and its solution is marvellous.

First problem that the producer faced is a shampooing/scraping tool need be detachably connected on the cleaning device.Also needing to design washing and rubbing utensil makes it allow the user to be independent of instrument use washing and rubbing utensil (for example cleaning unapproachable zone when scrubbing member is connected on the instrument).

In addition, when the user wishes to be connected to one a washing and rubbing utensil on the mophead that can be pivotally connected to a handle when removing obstinate dirt, he or she needs the rotary mop head to make the shampooing surface contact with dirt, props up dirt friction shampooing surface then.Promote rotation or the inclination that work can cause mophead shampooing operating period user drawing on handle.This rotation of mophead or inclination are made troubles for the shampooing operation and have been reduced the shampooing performance.

As following will from detailed disclosure know understand, the invention solves aforementioned misgivings.
