Retaining structure for brush of vapor cleaner

Abstract

A retaining structure for brush of vapor cleaner comprises a sheath pipe, a coupling means, a duct, a rotation means, a plurality of connection units, an upper cover and a bottom plate. The sheath pipe is connected to the duct; one end of the sheath pipe is connected to the rotation means. The rotation means is assembled with the upper cover. The connection units are arranged on the upper cover. The upper cover is assembled with the bottom plate. The vapor cleaner generates high-temperature vapor, and the vapor is sent to the bottom plate for emission through the duct. The connection units can be assembled with de-dirt paper or wipe for cleaning.

I claim:  
     
         1 . A retaining structure for brush of vapor cleaner, comprising 
 a sheath pipe of hollow shape and having a clamping board therein;    a coupling means arranged within the sheath pipe and being of hollow shape, the coupling means having a conic part and a guiding groove; the conic part piercing the clamping board in the sheath pipe and the guiding groove clamping the clamping board;    a duct having one end connected to the coupling means;    a rotation means composed of two semi-bodies, which enclose an outer wall of the duct, the rotation means having a top end pivotally connected to a bottom end of the sheath pipe;    an upper cover having two lugs on topside thereof and pivotally connected to the rotation means; and    a bottom plate assembled with the upper cover.    
     
     
         2 . The retaining structure for brush of vapor cleaner as in  claim 1 , wherein the sheath pipe has an opening at top end thereof and connected to a connection tube and a conveying tube of the vapor cleaner to convey vapor from the vapor cleaner.  
     
     
         3 . The retaining structure for brush of vapor cleaner as in  claim 1 , wherein the coupling means has one end invaginated with an annulus loop to enhance the coupling force between the coupling means and the conveying tube and prevent detach of the coupling means from the conveying tube.  
     
     
         4 . The retaining structure for brush of vapor cleaner as in  claim 1 , wherein the coupling means has a ring abutting an inner wall of the sheath pipe, thus preventing the coupling means from being inclined in the sheath pipe.  
     
     
         5 . The retaining structure for brush of vapor cleaner as in  claim 1 , wherein one end of the coupling means is invaginated with a first tightening ring, the first tightening ring enhancing the coupling force between the coupling means and the duct and preventing detach of the coupling means from the duct.  
     
     
         6 . The retaining structure for brush of vapor cleaner as in  claim 1 , wherein another end of the duct is invaginated with a second tightening ring and a nozzle, the second tightening ring enhancing the coupling force between the nozzle and the duct and preventing detach of the nozzle from the duct.  
     
     
         7 . The retaining structure for brush of vapor cleaner as in  claim 1 , wherein the upper cover has a plurality of recesses in which the connection units are fixed, and the connection unit has a slit on topside thereof, the slit used to clamp de-dirt paper or wipe for cleaning dirt.  
     
     
         8 . The retaining structure for brush of vapor cleaner as in  claim 1 , wherein the bottom plate has a rounded hole to lock the nozzle through vapor is emitted.  
     
     
         9 . The retaining structure for brush of vapor cleaner as in  claim 1 , wherein the bottom plate has a concave room used to accommodate the nozzle and prevent the jam of the nozzle.  
     
     
         10 . The retaining structure for brush of vapor cleaner as in  claim 1 , wherein the bottom plate has a plurality of orifices on one side thereof to increase the spraying area of high-temperature vapor and make uniform vapor emission.
