Rotational mop
A rotational mop includes a handle, a mop head and a plurality of cotton cloths. The mop head includes an installation disc, having a circular gutter formed on a top side of the installation disc, and a top side of two gutter walls is a serrated structure, and the cotton cloths are installed into the circular gutter and the serrated structure. The mop head further includes at least one serrated element embedded into the circular gutter, and a concave shape formed by a bottom side of the serrated element clamps the plurality of cotton cloths into the circular gutter in an M-shaped form. The installation disc can be connected directly to a bottom side of a turntable, or connected with a ring body first and then embedded into the bottom side of the turntable, so that the cotton cloth can be rotated together with the turntable in 360 degrees.
1. Field of the Invention
The present invention relates to a rotational mop, and more particularly to a mop having cotton cloths fixed at a mop head capable of rotating in 360 degrees, and engaged with the mop head in an M-shaped form for preventing the mop head from falling out.
2. Description of the Related Art
Mop is a common tool used for cleaning a floor, and a traditional mop is generally comprised of a handle and a cotton cloth fixed to the bottom of the handle, and the traditional mop is generally operated by applying forces back and forth on a tilted handle, and driving the cotton cloth to move back and forth on the floor in order to clean the floor.
However, a force is usually applied to the traditional mop to drive the cotton cloth at the bottom of the handle to be in contact with the floor, and thus the cleaning effect is limited to the area where the cotton cloth is in contact with the floor only, and the cleaning effect of the mop is very limited. After a long time of use, the contact portion of the cotton cloth becomes dirty, and users have to change the direction of the handle in order to contact the floor with another portion of the cotton cloth for a continual cleaning effect. Obviously, the traditional mop is not convenient at all. Furthermore, a joint between the handle and the cotton cloth of the traditional mop usually comes with a large size, so that the mop cannot be used for cleaning hard-to-reach spots such as wall corners, table legs or crevices under objects effectively, and the application of the traditional mop is limited. Since the handle and the cotton cloth of the traditional mop do not have any special design, therefore a dirty cotton cloth will no longer have the effective cleaning effect anymore, and users have to discard the whole mop, and thus the prior art wastes resources.
Even though the traditional mop can overcome the aforementioned problems, yet no special design for connecting the cotton cloth with the mop head is found in the common rotational mops available in the market to overcome the problem of having the cotton cloth pulled away and separated from the mop head easily. As a result, the traditional rotational mop has a short life expectancy.
SUMMARY OF THE INVENTIONA primary object of the present invention is to overcome the shortcomings of the prior art by providing a rotational mop, whose mop head and cotton cloth can be rotated in 360 degrees, and the cotton cloth is engaged securely by the mop head in a M-shaped form to prevent the cotton cloth from falling out.
In order to achieve the above-mentioned object, a rotational mop of the invention includes:
a) a handle, composed of at least one section of rod, and a pivoting head installed at an end of the handle;
b) a mop head, pivotally coupled to the pivoting head; and
c) a plurality of cotton cloths, fixed at a bottom end of the mop head; characterized in that the mop head further comprises:
i) an installation disc, having at least one insert hole and a penetrating hole formed thereon, a circular gutter disposed at the top side of the installation disc, wherein a top side of two gutter walls of the circular gutter is a serrated structure, and the cotton cloth is installed in the circular gutter and the serrated structure;
ii) at least one serrated element, provided for being embedded into the circular gutter, and the bottom side of the serrated element forming a concave shape, such that the plurality of cotton cloths are clamped and fixed into the circular gutter in a M-shaped form;
iii) a turntable, having a connecting hole disposed at the center of the turntable, and at least one protruding pillar disposed at the bottom of the turntable, and disposed at a position corresponding to the insert hole of the installation disc for coupling the protruding pillar with the insert hole; and
iv) a connecting component, for connecting the turntable with the pivoting head, such that the turntable is a structure capable of rotating 360 degrees with respect to the handle, and the cotton cloth can be driven to rotate 360 degrees together with the turntable.
According to the invention, the protruding pillar disposed at the bottom side of the turntable is integrally formed with the turntable.
Moreover, the protruding pillar disposed at bottom side of the turntable is formed independently at the bottom side of a ring body, and a penetrating hole is formed at the center of the ring body, and the ring body has a n-shaped cross-section, and a bump is formed at an external side of the ring body, and provided for being embedded and latched into an internal side of a wall of the turntable.
Besides, the connecting component includes an installing element and a latch element, and the installing element includes a pivoting base and a plurality of latch notches. The installing element has an external periphery substantially larger than the connecting hole, such that the pivoting base is protruded out from the connecting hole. The installing element is installed into the penetrating hole. The latch element includes a through hole and plurality of elastic latches, wherein after the pivoting base is protruded out from the connecting hole and the through hole, the elastic latch is latched into the latch notch, and the pivoting base and the pivoting head are engaged with each other into a pivotal connection form, such that the turntable is clamped and fixed into the installing element and the latch element.
Furthermore, the connecting component is comprised of an installing body and at least one latching body, and the installing body is pivotally coupled to the pivoting head by a lug base formed at the top side of the installing body. A concave circular gutter is formed at an external periphery of the installing body, and the latching body is comprised of two symmetric casings, and the latching body includes an embedding semicircular necking portion disposed on the internal side of the latching body and opposite to the concave circular gutter, such that when the two latching bodies are integrated with each other, the two latching bodies are covered onto the external periphery of the concave circular gutter to define a structure capable of rotating in 360 degrees with respect to the handle. The latching body includes a plurality of latch portions disposed at the external periphery of the latching body and coupled with the plurality of latch holes disposed on the periphery of the connecting hole for installing and fixing the latching body and the turntable, so that the turntable can be rotated in 360 degrees with respect to the installing body and the handle.
