The use of "vertical," "horizontal," "left," "right," and similar expressions are for illustrative purposes only and are not meant to be the only embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Fig. 1-11 illustrate a rotary mop according to a preferred embodiment of the present invention, including a mop rod 100 and a mop head 200.

Referring to fig. 3 and 4, the tow bar 100 includes a screw cylinder 110, a lifting bar 120, a swivel head 130, a stopper link 140, and a linkage support cylinder 150.

Referring to fig. 6, the screw cylinder 110 is provided with an internal screw 111 spirally extending in the axial direction of the screw cylinder 110; the rotating head 130 is accommodated in the threaded cylinder 110, and the lifting rod 120 is connected with the rotating head 130 in a linkage manner so that the rotating head 130 moves up and down relative to the threaded cylinder 110 along with the lifting rod 120; the side surface of the rotary head 130 for slidably connecting the internal thread 111 is a first side surface 131 (see fig. 7), the side surface of the internal thread 111 for slidably connecting the rotary head 130 is a second side surface 1111, and the first side surface 131 is attached to the second side surface 1111, so that the rotary head 130 and the threaded cylinder 110 are in a surface contact fit relationship. In this way, the rotary head 130 and the screw cylinder 110 can be relatively rotated and lifted. The specific working mode is that the lifting rod 120 is connected with the handle of the rotary mop, so when the handle is controlled by a hand to descend, the lifting rod 120 is linked to descend, the rotary head 130 abuts against the internal thread 111, the rotary head 130 is controlled by the lifting rod 120 to be unable to rotate, and the rotary head 130 and the internal thread 111 are in spiral fit relation, so that the threaded cylinder 110 is forced to rotate around the axis of the threaded cylinder. Thus, the threaded cylinder 110 is coupled with the mop head 200 to rotate the mop head 200. Importantly, the pressure between the rotary head 130 and the threaded cylinder 110 is greatly reduced by making surface contact between the first side 131 of the rotary head 130 and the second side 1111 of the internal thread 111 of the threaded cylinder 110 instead of the prior art line contact, so that the internal thread 111 of the threaded cylinder 110 is not easily worn.

Referring to fig. 6, the bottom cover 112 of the threaded cylinder 110 is inserted into the bottom of the threaded cylinder 110, the top of the locking connection seat 140 is abutted against the bottom cover 112, the linkage support cylinder 150 is sleeved outside the threaded cylinder 110 and is axially locked and connected with the threaded cylinder 110, and the locking connection seat 140 is also accommodated in the linkage support cylinder 150 and is axially locked and connected with the linkage support cylinder 150; the reserve area 1121 enclosed by the bottom cap 112 and the screw cylinder 110 is filled with lubricating oil. Before the bottom cover 112 is installed, the storage area 1121 is filled with lubricating oil, and then the bottom cover 112 is installed on the threaded cylinder 110, so that the matching between the rotating head 130 and the threaded cylinder 110 can be more flexible and the abrasion is smaller due to the lubricating oil. Through the axial fixation of the linkage support cylinder 150 and the threaded cylinder 110, the linkage support cylinder 150 can axially fix the stop connection seat 140, that is, the threaded cylinder 110, the linkage support cylinder 150 and the stop connection seat 140 are axially relatively static together, so that the bottom cover 112 supported by the stop connection seat 140 is also axially fixed without falling off. The arrangement is based on that the lifting rod 120 frequently generates axial impact force, so that the bottom cover 112 can be separated, and the bottom cover 112 is supported by the stop connection seat 140, so that the problem of lubricating oil loss caused by falling of the bottom cover 112 is solved, and the service life of the rotary mop is further prolonged.

Referring to fig. 6, the detent connection 140 is hinged with the mop head 200 such that the detent connection 140 can drive the mop head 200 to spin water.

It should be noted that, instead of a friction connection, the interlocking support cylinder 150 and the threaded cylinder 110 are preferably fixedly connected in a radial direction, so as to avoid slipping. And, the interlocking support cylinder 150 and the stopper link 140 are preferably also fixedly connected in a radial direction instead of the frictional connection so as to avoid the slipping phenomenon. The radial fixing mode includes bonding, riveting and the like.

Preferably, the first side 131 and the second side 1111 are both planar structures; alternatively, the first side 131 and the second side 1111 are both arc structures, and one of the first side 131 and the second side 1111 wraps the other. Obviously, the planar structure is easier to process, and the requirements on the processing precision and the matching precision of the cambered surface structure are higher, so that the cambered surface structure is relatively difficult to manufacture. Alternatively, a third side surface and a fourth side surface may be respectively designed on the rotary head 130 and the thread cylinder 110, and the third side surface and the fourth side surface may be both planar structures or both cambered structures, that is, by a mode of mixing and grouping the planar structures and the cambered structures, so as to further reduce the pressure intensity of the contact surface. More preferably, in order to improve the stability of the movement of the spin head 130, the internal thread 111 is provided in plurality, and the plurality of internal threads 111 are independent from each other and are provided at intervals along the circumferential direction of the thread cylinder 110; the spin head 130 is provided with a plurality of first side surfaces 131, and the plurality of first side surfaces 131 are bonded to the plurality of second side surfaces 1111 in a one-to-one correspondence.

Referring to fig. 6, the rotator head 130 preferably has a central aperture 132 (see fig. 7); the lifting rod 120 is provided with a matching part 121 and a limiting part 122 at intervals along the length direction of the lifting rod 120, and the lifting rod 120 movably penetrates through the central hole 132; the mating part 121 is provided with a stop tooth surface 1211, the swivel head 130 is provided with a stopped tooth surface 133, and the stop tooth surface 1211 is adapted to the stopped tooth surface 133. The rotary head 130 is located between the limit part 122 and the mating part 121, and is capable of axial play between the mating part 121 and the limit part 122 with respect to the lifter 120 to engage or disengage the stop tooth surface 1211 with the stopped tooth surface 133. The best working mode is as follows: when the lifting rod 120 descends, the stop tooth surface 1211 and the stopped tooth surface 133 are engaged, so that the lifting rod 120 and the rotating head 130 are temporarily locked together, and the thread cylinder 110 is forced to rotate by the descending of the rotating head 130; when the lifting rod 120 is lifted, the rotating head 130 is separated from the matching part 121 under the driving of gravity and is supported by the limiting part 122, so that the lifting rod is lifted along the internal thread 111 in a spiral rotation manner. In this way, the lifting rod 120 does not need to rotate around the axis in the lifting process, so that the handle does not need to rotate in the process of pulling up the handle by a human hand, and the convenience of use is improved. That is, as an alternative arrangement: the lifting rod 120 may be directly fixed to the rotary head 130, but in this way, the lifting rod 120 needs to rotate around its own axis during lifting. More preferably, the elevating bar 120 is recessed from the outside to the inside in the radial direction thereof to form a recess portion in order to prevent the loosening thereof based on the necessity of frequently pressing the rotating head 130 by the fitting portion 121, and the fitting portion 121 is welded to the outer periphery of the elevating bar 120 by injection molding and fills the recess portion. In the present embodiment, the limiting portion 122 is a wire and is disposed through the transverse through hole 134 of the lifting rod 120.

Preferably, referring to fig. 4 and 3, the top of the lifting rod 120 is movably penetrated through the top cover of the screw cylinder 110, the lifting rod 120 is connected with an elastic deformation buffer 160, and the elastic deformation buffer 160 is located right above the top cover of the screw cylinder 110. When the elastically deforming buffer 160 is just abutted against the top cover of the screw cylinder 110, the bottom of the elevating rod 120 is located above the reserve area 1121 (see fig. 6). So configured, when the reserve area 1121 is filled with the spare lubricant and the lifter 120 descends itself, the bottom of the lifter 120 cannot access the lubricant in the reserve area 1121, and if the lifter 120 is forcibly pushed down by a human hand to rotate the screw cylinder 110, the elastically deforming buffer 160 is pressed by the top of the lifter 120 so that the lifter 120 breaks through the lower limit height, thereby accessing the lubricant. Among them, the lubricating oil is preferably butter.

Preferably, referring to fig. 4, a screw head 170 is fixedly connected to the top of the lifting rod 120, and the screw head 170 is used for being screwed with a handle of the rotary mop; the bottom of the screw head 170 is fixedly sleeved with a protection cylinder 180, and the linkage support cylinder 150 is movably sleeved in the protection cylinder 180, so that when the screw head 170 drives the lifting rod 120 to descend, the protection cylinder 180 is in a non-rotating state, and the screw head 170 is in a rotating state.

Preferably, referring to fig. 1, the rotary mop further comprises a locking mechanism 300, wherein the locking mechanism 300 comprises an inner sleeve 310 and an outer sleeve 320, and the outer sleeve 320 is sleeved outside the inner sleeve 310 and is in threaded connection with the inner sleeve 310; the inner sleeve 310 is fixedly connected to the shield cylinder 180 and the outer sleeve 320 is capable of clamping the interlocking support cylinder 150. Thus, the locking mode is a rotary sleeve 320, and the locking mode is reliable and convenient. Obviously, the locking mode can also imitate the adjusting mode of the telescopic rod of the standing fan.

Preferably, referring to fig. 1 and 2, the retaining connection base 140 is pivotally connected to the hinge base 230 of the mop head 200 by the swing lever 190 (wherein the retaining connection base 140 is in threaded connection with the swing lever 190). Referring to fig. 8 to 10, the hinge base 230 is inserted through the central through hole 211 of the rotating plate 210 of the mop head 200, the swing rod 190 is pivoted with the hinge base 230 through a horizontal pivot shaft, one of the swing rod 190 and the mop head 200 is provided with a radial protrusion 223, the other is provided with a radial groove 1921, and the radial protrusion 223 is engaged with the radial groove 1921, so that the swing rod 190 and the mop head 200 are radially and cooperatively connected. By the arrangement, the swinging rod 190 and the mop head 200 are in radial linkage, so that the two cannot mutually slip, and the phenomenon that the swinging rod 190 in driving connection with the handle idles (namely, the mop head 200 is stationary relative to the mop bucket) is avoided.

Preferably, referring to fig. 9, the swing lever 190 includes a lever body 191 and a radial stopper cover 192 that are independent of each other, and the lever body 191 and the radial stopper cover 192 can be locked to each other; the lever body 191 is pivoted with the hinge seat 230, and the radial stop gland 192 covers the top of the mop head 200, and the radial groove 1921 or the radial protrusion 223 is disposed on the radial stop gland 192. The device is arranged in such a way that the hinge seat 230 of the mop head 200 and the radial stop gland 192 of the swinging rod 190 are radially fixed, and the rod main body 191 and the radial stop gland 192 can relatively move, so that when the rod main body 191 and the radial stop gland 192 are mutually locked, the device is used for throwing water of the mop head 200, and when the rod main body 191 and the radial stop gland 192 are unlocked, the device is used for mopping the floor, and the function that the mop head 200 can rotate relative to the rod main body 191 is reserved, so that the mop head 200 can mop the floor cleaner. The locking manner between the lever main body 191 and the radial stopper gland 192 may be: when the lever body 191 is in a vertical manner, the two are engaged with each other, magnetically connected, and the like. As can be appreciated from the prior art, the blind hole 231 of the base of the hinge base 230 is used to match the mop bucket.

Preferably, referring to fig. 10 and 11, the rotating plate 210 of the mop head 200 is provided with an inner ring through hole group 212 and an outer ring through hole group 213; the inner ring through hole group 212 includes a plurality of first through holes 2121, the plurality of first through holes 2121 being disposed at intervals around the axis of the rotating plate 210; the outer ring through hole group 213 includes a plurality of second through holes 2131, and the plurality of second through holes 2131 are provided at intervals around the axis of the rotary plate 210; the outer ring through hole group 213 is surrounded on the outer periphery of the inner ring through hole group 212. Obviously, by adding the inner ring through hole group 212 in the outer ring through hole group 213, the inner ring through hole group 212 is closer to the axis of the rotating plate 210; thus, after the mop head 200 is soaked in water, the weight of the mop cotton rope is greatly increased after absorbing water, so that the gravity center of the mop head 200 is more inward, and when the mop head 200 and the rotating shaft of the mop bucket are matched to throw water, the gravity center of the mop head 200 is smaller in outward offset, and the relative rotation process between the mop head 200 and the mop bucket is smoother. It should be noted that, in the conventional art, only the outer ring through hole group 213 is provided, and after the mop head 200 is immersed in water, the weight of the cotton rope is greatly increased, so that the center of gravity of the mop head 200 is more outward during the rotation process, and the phenomenon that the mop head 200 is separated from the rotation axis of the mop bucket is easily caused.

Referring to fig. 10, in order to cover the cotton string to prevent the cotton string from being torn, the mop head 200 further includes a disk-shaped housing 220, an outer edge of the disk-shaped housing 220 protrudes downward to form a fixed connection ring 221, a middle portion of the disk-shaped housing 220 has a through hole 222 for avoiding, the disk-shaped housing 220 is sleeved with the rotating plate 210 from top to bottom, so that the fixed connection ring 221 of the disk-shaped housing 220 is fixedly sleeved on the periphery of the rotating plate 210, and the through hole 222 for avoiding is coaxially arranged with the central through hole 211. The disc-shaped housing 220 is also provided with an annular receiving recess 224 for receiving the radial stop gland 192.

The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
