Automatic rotating mop

Abstract

An automatic rotating mop includes a force applying rod and a rotating rod. The force applying rod includes an external tube and a holding element installed at an upper end of the external tube. The external tube includes a braking rod and a spiral track formed on the braking rod. The rotating rod includes an internal tube having an internal diameter smaller than the external tube for coupling the external tube, a rotating disc coupled to the internal tube, and a rotating element corresponding to the braking rod and coupled to the internal tube. When the external tube is moved vertically towards the rotating disc, the rotating element is winded along the spiral track to produce a rotation movement, and linked to the internal tube and the rotating disc to rotate jointly to remove water from the mop by a rotating force.

1 . An automatic rotating mop, comprising:
 a force applying rod, including an external tube and a holding element installed at an upper end of the external tube, and a braking rod installed at the external tube, and the braking rod having a spiral track thereon;   a rotating rod, including an internal tube having an internal diameter smaller than the external tube and coupled to the external tube, a rotating disc coupled to the internal tube, and a rotating element corresponding to the braking rod and coupled to the internal tube, such that the external tube can be moved vertically towards the rotating disc to drive the rotating element to wind along the spiral track to produce a rotating movement and to link with the internal tube and the rotating disc to rotate jointly.   
     
     
         2 . The automatic rotating mop of  claim 1 , wherein the rotating element includes a rotating base disposed at an end of the internal tube, and a driving element installed at the rotating base and moved along the spiral track. 
     
     
         3 . The automatic rotating mop of  claim 2 , wherein the rotating base includes a containing hole for containing the driving element, and a fixing element sheathed and coupled to the external side of the rotating base for fixing the driving element. 
     
     
         4 . The automatic rotating mop of  claim 3 , wherein the driving element is a steel ball. 
     
     
         5 . The automatic rotating mop of  claim 2 , wherein the rotating element further includes a limiting element installed between the internal tube and the rotating base for rotating the internal tube unidirectionally. 
     
     
         6 . The automatic rotating mop of  claim 5 , wherein the limiting element is a one-way bearing. 
     
     
         7 . The automatic rotating mop of  claim 5 , further comprising a sheathing element installed between the limiting element and the internal tube, the sheathing element being positioned at the internal tube by a positioning element. 
     
     
         8 . The automatic rotating mop of  claim 7 , wherein the sheathing element includes a rotation assisting element separately installed at both ends of the sheathing element for assisting the rotation of the rotating base. 
     
     
         9 . The automatic rotating mop of  claim 8 , wherein the rotation assisting element is a planar bearing. 
     
     
         10 . The automatic rotating mop of  claim 1 , wherein the external tube includes a fastening element installed outside the external tube for providing a fastening force to limit ascending and descending displacements of the external tube. 
     
     
         11 . The automatic rotating mop of  claim 10 , wherein the fastening element includes a clamping element and a force applying element coupled to the clamping element and having engaged/disengaged positions, such that the clamping element can produce a fastening force. 
     
     
         12 . The automatic rotating mop of  claim 1 , further comprising an auxiliary rod installed between the rotating disc and the external tube, the auxiliary rod providing for a length extension. 
     
     
         13 . The automatic rotating mop of  claim 1 , wherein the braking rod includes an abutting element for abutting against the holding element. 
     
     
         14 . The automatic rotating mop of  claim 1 , wherein the internal tube includes an elastic element for supporting the braking rod.
