Rotary mop device

Abstract

A rotary mop device comprises a mop tube, a push-to-rotation means, a thread strip and a mop frame body. The mop tube is consist of a first mop tube and a second mop tube, the push-to-rotation has a case body with a driving element and an engaging corresponding element being provided in the case body, the case body being provided on the inner surface of the second mop tube, the driving element has a plural bump engaging parts and the engaging corresponding element has a plural bump engaging parts, the thread strip is fixed on inner surface of the mop tube, the mop frame body is provided below the second mop tube.

1 . A rotary mop device, comprising:
 means of mop tube, having a first mop tube and a second mop tube, the first mop tube bonding with the upper portion of the second mop tube, the outer diameter of the second mop tube being smaller than the outer diameter of the first mop tube;   a thread strip, having thread structure on the surface thereof, the upper portion of the thread strip being fixed on inside surface of the means of mop tube;   means of push-to-rotation, having a case body with a driving element and an engaging corresponding element provided in the case body from up to down, the case body being provided on the inner surface of the second mop tube, wherein a convex structure is provided on the lower surface of the driving element, a plural bump engaging parts being provided on the convex structure, a concave structure being provided on inner upper surface of the engaging corresponding element, engaging corresponding parts being provided on the outer surface of the concave structure to correspond to the plural bump engaging parts, a gap provided between outer diameter of the driving element and inner diameter of the case body, the engaging corresponding parts being fixed on the inner surface of the case body;   a mop frame body, having a mop frame and a mop cotton, the mop frame being provided below the means of mop tube;   wherein when the first mop tube is being pushed downward, the driving means is pushed downward by the applied force from the thread structure of the thread strip, so that the plural bump engaging parts are engaged with the engaging corresponding parts, and while the first mop tube is being pushed downward, the case body of the means of push-to-rotation is rotated by the applied force from the thread structure so that the second mop tube is thus rotated,   wherein when the first mop tube is being pulled upward, the driving element is pulled upward by the applied force from the thread structure of the thread strip, so that the plural bump engaging parts are separated from the engaging corresponding parts to pull the first mop tube,   wherein a central hole of the engaging corresponding parts is always not applied by the force from the thread body of the thread strip.   
     
     
         2 . The rotary mop device as claimed in  claim 1 , wherein the upper portion of the thread strip is fixed on the inner surface of the first mop tube. 
     
     
         3 . The rotary mop device as claimed in  claim 1 , wherein the concave structure in the lower portion of the driving element is a cone shape body, and the bump engaging parts are bump structure being lengthwise provided. 
     
     
         4 . The rotary mop device as claimed in  claim 1 , wherein upper portion of the engaging corresponding parts of the engaging corresponding element is a concave structure with cone shape. 
     
     
         5 . The rotary mop device as claimed in  claim 1 , wherein the means of push-to-rotation is provided on the inner surface of the upper portion of the second mop tube. 
     
     
         6 . The rotary mop device as claimed in  claim 1 , wherein the means of mop tube is able to be lengthened, and the second mop tube is able to move upward or downward in the inner surface of the first mop tube. 
     
     
         7 . The rotary mop device as claimed in  claim 1 , wherein a balancing element is provided in the case body and is under the engaging corresponding element. 
     
     
         8 . The rotary mop device as claimed in  claim 1 , wherein the second mop tube is able to move up and down in the inner diameter of the first mop tube.
