Detailed Description

Embodiments of the present invention will be described below with reference to fig. 1A to 8. The description is not intended to limit the embodiments of the present invention, but is one example of the present invention.

Referring to fig. 1A to 4, a mop head 100 according to an embodiment of the present invention is detachably and replaceably disposed on a mop head base fixing member 31, wherein two mop head base fixing members 31 are pivotally connected to each other and connected to a mop holding rod 32 through a rotating sleeve connecting member 30, so as to form a foldable mop which can be folded and unfolded for mopping and cleaning. The mop head 100 comprises: a mop head base 1, wherein a plurality of joining recesses 11 (shown in fig. 1B and 3B) are formed on a lower surface 102 of the mop head base 1, inner wall surfaces of the joining recesses 11 include an upper wall surface 111 and a side wall surface 112, the side wall surface 112 has a threaded concave-convex surface 12, the joining recesses 11 are blocked by the upper wall surface 111 to form a non-porous blocking member 13 (shown in fig. 4) at the tops of the joining recesses 11, and the non-porous blocking member 13 and the mop head base 1 are integrally molded; and a cleaning member 2, as shown in fig. 1B and 6, the cleaning member 2 is fixed by the screw-shaped concave-convex surface 12 of the side wall surface 112 and is fixedly accommodated in the joint concave portion 11. The cleaning member 2 may be a cotton cloth strip, but the specific implementation is not limited thereto.

Specifically, as shown in fig. 1A to 3B, the mop head base 1 of the present invention is a mop head base fixing member 31 configured to be removably coupled to a mop head, thereby facilitating a user to use a mop formed of the mop head 100 of the present invention. Specifically, a fixed slide rail 103 is formed on the upper surface 101 of the mop head base 1 and is slidably engaged with the fixed chute 311 of the mop head base fixing member 31 in a transverse moving manner; the fixing sliding slot 311 is formed at the bottom of the mop head base fixing member 31, and the top surfaces of the two mop head base fixing members 31 are connected with the mop holding rod 32 through the rotating sleeve connecting member 30 in a manner of being capable of pivoting relative to the mop holding rod 32 to form the folding mop. When the mop head base 1 is combined with the mop head base fixing member 31, the button 110 of the mop head base 1 is located at the opening 310 of the mop head base fixing member 31 for being pressed by a user (please refer to fig. 1A and fig. 2 at the same time). When a user wants to remove the mop head base 1, the button 110 (as shown in fig. 2) disposed on the upper surface 101 of the mop head base 1 is pressed to release the locking relationship between the mop head base fixing member 31 and the mop head base 1, so that the mop head base 1 can be separated from the fixing chute 311 of the mop head base fixing member 31.

Specifically, as shown in fig. 4, the screw-shaped concave-convex surface 12 of the mop head base 1 is formed spirally on the side wall surface 112 of the mop head base 1 from the lower surface 102 of the mop head base 1 toward the upper surface 101 of the mop head base 1 along a depth extending direction of the side wall surface 112 of the engagement recess 11; referring to fig. 5, the screw-shaped concave-convex surface 12 may be formed by rotating a mold T having an outer surface with a screw structure into an inner wall surface of the joining concave portion 11 to form the screw-shaped concave-convex surface 12 on the side wall surface 112 when the mop head base 1 and the joining concave portion 11 are formed by injection molding, and rotating the mold having the outer surface with a screw structure out of the joining concave portion 11 after the screw-shaped concave-convex surface 12 is formed. The cross-sectional profile of the threaded concave-convex surface 12 is in the shape of a cuspate tooth. Further, the cross-sectional shape of the threaded concave-convex surface 12 of the present invention is not limited to the shape of a cusp, but the cross-sectional shape of the threaded concave-convex surface 12 may be other shapes, such as: semicircular or square (not shown in the drawings).

Specifically, referring to fig. 2, fig. 7 and fig. 8, each of the two mop base holders 31 includes a wing body 312, and the two mop base holders 31 are pivotally connected to a synchronization connection member 313. The rotating sleeve connection member 30 is sleeved at the shaft portion of the synchronous connection member 313 and connected to the mop handle 32, wherein the rotating sleeve connection member 30 can rotate relative to the shaft portion of the synchronous connection member 313 along with the variation of the force application angle when the user mops the floor. The wing bodies 312 are configured to be detachably and replaceably connected to the mop head base 1, and the two wing bodies 312 are pivotally connected to two wing connecting portions 314 at two ends of the synchronous connecting member 313 in a manner of synchronously closing or synchronously unfolding relative to the synchronous connecting member 313, wherein the pivoting portion 315 of the wing body 312 is pivotally connected to the wing connecting portion 314 of the synchronous connecting member 313 through the connecting pin 304. Further, the synchronization member 301 (in this embodiment, a push-pull rod) is inserted into the synchronization link 313 through a slot at the bottom of the synchronization link 313, and both ends of the synchronization member 301 are mounted to the corresponding engagement holes 303 of the flap body 312 through the corresponding engagement pins 302.

Referring to fig. 1A, fig. 7 and fig. 8, each wing plate 312 has a wing plate positioning set 316, and the wing plate positioning set 316 abuts against the folding positioning portion 331 or the unfolding positioning portion 332 of the wing plate connecting portion 314 of the synchronous connecting member 313. When the two wing plate bodies 312 are unfolded, the wing plate positioning group 316 of the wing plate body 312 is abutted against the unfolding positioning part 332 of the wing plate connecting part 314; when the two wing plates 312 are closed, the wing plate positioning set 316 of the wing plate 312 abuts against the folding positioning portion 331 of the wing plate connecting portion 314. The wing positioning set 316 is disposed on the inner side wall of the groove of the pivoting portion 315 of the wing body 312. Specifically, the wing positioning set 316 has an elastic member 317 and a positioning member 318, the positioning member 318 is disposed at an end of the elastic member 317 and is capable of protruding out of an inner sidewall surface of the groove of the pivot portion 315 to abut against the folding positioning portion 331 or the unfolding positioning portion 332 of the wing connecting portion 314, wherein the folding positioning portion 331 and the unfolding positioning portion 332 are recesses formed in the groove of the wing connecting portion 314.

In the mop head 100 of the present invention, the upper wall surface 111 of the engaging recess 11 of the mop head base 1 and the thread-like concave-convex surface 12 on the side wall surface 112 are formed, so that the upper wall surface 111 forms the nonporous stopper 13, and the frictional resistance between the cleaning member 2 and the side wall surface 112 of the engaging recess 11 is formed by the shape (e.g., pointed tooth shape, semicircular shape, square shape) of the thread-like concave-convex surface 12, thereby preventing the displacement of the cleaning member 2 relative to the engaging recess 11 of the mop head base 1. Thus, the mop head 100 of the present invention has the upper wall 111 of the joining recess 11 of the mop head base 1 closing one end of the joining recess 11 to form the non-porous blocking member 13, so that the disadvantage of dirt accumulation at the perforated part of the mop head base of the conventional rotary mop and folding mop can be improved, and the cleaning member 2 is not easily detached from the mop head base 1 of the mop head 100 due to the formation of the screw-shaped concave-convex surface 12.

The shape of the cross-sectional profile (i.e., pointed tooth, semicircular, square) of the threaded concave-convex surface 12 of the mop head base 1 of the present invention is related to the frictional resistance between the cleaning member 2 and the side wall surface 112 of the engaging concave portion 11, thereby improving the disadvantage that the cleaning member is easily detached from the mop head base of the prior art rotary mop and folding mop. In other words, the cleaning member 2 is less likely to fall off from the mop head base 1 by adjusting the magnitude of frictional resistance between the screw-shaped uneven surface 12 and the cleaning member 2 by changing the contact area between the side wall surface 112 of the engaging recess 11 and the cleaning member 2 by changing the cross-sectional shape of the screw-shaped uneven surface 12.

Furthermore, mop head base 1 is blocked in the bottom surface of mop head base mounting 31 with the mode card that slides and sets up for the user can take out mop head base 1 along with the demand, in order to carry out the old-out of mop head base 1 and trade newly. The wing plates 312 of the mop head base fixing member 31 are abutted against the folding positioning portions 331 or the unfolding positioning portions 332 of the wing plate connecting portions 314 of the synchronous connecting members 313 through the wing plate positioning sets 316, so that the positioning between the wing plates 312 and the synchronous connecting members 313 is obtained in the process of synchronously closing or unfolding the two wing plates 312.

While the foregoing description and description are of the preferred embodiment of the present invention, other modifications will become apparent to those skilled in the art from the foregoing description and it is intended that such modifications be included within the spirit and scope of the present invention.
