Abstract

A mop with the function of dewatering the yarns by twisting in a single direction via an up-and-down linear motion, comprising: a) an internal rod; b) an external rod having a bottom portion in a telescopic connection with a top portion of the internal rod; c) an engaging element positioned within the opening at the top of the internal rod; d) a driving element formed in an elongated shape and positioned within the external rod in such a way that the driving element is moved up and down synchronically with the external rod; e) an actuating element positioned within the engaging element for accommodating the driving element, the engaging element being driven in a single direction when the actuating element is rotated by the driving element; f) a disc body secured to the bottom thereof and having mop yarns; g) a locking mechanism mounted on the external rod for locking the internal rod and the external rod in place or for unlocking them in a telescopic state, wherein the actuating element is rotated by a linear motion of the driving element when the external rod is moved up-and-down; moreover, the engaging element is driven in rotation in a single direction, thereby creating a continuous rotation of the internal rod and the disc body in the same direction by the inertia force; as a result, a centrifugal force is produced to throw away the water absorbed in the mop yarns. In this way, the mop yarns may be dewatered in a more convenient and safer way.

Claims

1. A mop with the function of dewatering the yarns by twisting in a single direction via an up-and-down linear motion, comprising:

a) an internal rod;

b) an external rod having a bottom portion in a telescopic connection with a top portion of the internal rod;

c) an engaging element positioned within the opening at the top of the internal rod;

d) a driving element formed in an elongated shape and positioned within the external rod in such a way that the driving element is moved up and down synchronically with the external rod;

e) an actuating element positioned within the engaging element for accommodating the driving element, the engaging element being driven in a single direction when the actuating element is rotated by the driving element;

f) a disc body secured to the bottom thereof and having mop yarns;

g) a locking mechanism mounted on the external rod for locking the internal rod and the external rod in place or for unlocking them in a telescopic state,

wherein the actuating element is rotated by a linear motion of the driving element when the external rod is moved up-and-down;

moreover, the engaging element is driven in rotation in a single direction, thereby creating a continuous rotation of the internal rod and the disc body in the same direction by the inertia force;

as a result, a centrifugal force is produced to throw away the water absorbed in the mop yarns.

2. The mop with the function of dewatering the yarns by twisting in a single direction via an up-and-down linear motion as recited in claim 1 wherein the driving element is constructed as a worm or a threaded piece, and wherein the actuating element receiving the driving element is constructed as a threaded sleeve such that the driving element drives the actuating element in rotation when the driving element is linearly moved up-and-down.

3. The mop with the function of dewatering the yarns by twisting in a single direction via an up-and-down linear motion as recited in claim 1 wherein the engaging element is positioned at the top of the internal rod and fixed by an annular element and a fixing cap in place, and wherein the engaging element includes a plurality of upward engaging teeth at the internal rim of the bottom of thereof while the bottom of the actuating element is provided with downward engaging teeth corresponding thereto such that the rotation of the actuating element may cause a one-way rotation of the engaging element.

4. The mop with the function of dewatering the yarns by twisting in a single direction via an up-and-down linear motion as recited in claim 3 wherein the upper portion of the engaging element is externally provided with a flange while the internal rim thereof includes an annular groove, and wherein the fixing cap includes a projecting rib at the external rim thereof such that the projecting rib can fit into the annular groove of the engaging element in place.

5. The mop with the function of dewatering the yarns by twisting in a single direction via an up-and-down linear motion as recited in claim 1 wherein the locking mechanism includes:

a) a clamping sleeve fastened at the bottom of the external rod, the lower portion thereof having an indentation, an inclined groove being formed at the periphery thereof; and

b) a rotating sleeve mounted on the clamping sleeve with a projecting portion corresponding to the inclined groove of the clamping sleeve for moving up-and-down within the inclined groove,

whereby the clamping sleeve may be tightened or loosened by the rotating sleeve, and due to the action of the indentation, the locking the internal rod and the external rod may be locked by the clamping sleeve in place for cleaning the floor, or the internal rod may be driven in a rotary state for dewatering the mop yarns.

6. The mop with the function of dewatering the yarns by twisting in a single direction via an up-and-down linear motion as recited in claim 5 wherein the internal top portion of the clamping sleeve is provided with a plurality of locking hooks spaced apart from each other, and wherein the external rod includes corresponding holes into which the locking hooks fit, and wherein, when the external rod is pulled upward to a certain height, the locking hooks may be hooked on the fixing cap within the internal rod in place.

7. The mop with the function of dewatering the yarns by twisting in a single direction via an up-and-down linear motion as recited in claim 1 wherein the disc body includes a dewatering basket rotatable within a bucket body, and wherein the dewatering basket may be synchronically driven in rotation when the disc body is rotated by the internal rod;

in this way, the mop yarns of the disc body are subject to the centrifugal force for dewatering, and, the water removed may be received within the bucket body.
