particularly to a rotary mop having simple structure and good
stability without improper shaking happened in operation.
[0003] 2. Brief Description of the Prior Art
[0004] Mop is a prevalent means to clean hard surface areas such as
floor. People firstly clean floors with a broom, then use a mop
adsorbed with water to cohere dust, detritus and greasy dirt by the
adhesion action of water contained in the mop strings. In turn, the
mop strings is dipped in the water bucket or the dirt adhered
thereon is washed by water and the water contained in the mop
strings is then wrung out. The wiping action of mop is repeatedly
conducted for a couple of times such that the floor becomes more
and more clean.
[0005] However, as the water contained in ordinary mop strings is
usually wrung out by hands, it is disadvantageous for users both on
hygiene and safety that users might easily suffer from damage if
the mop is adhered with sharp stuff like splinters of glass or iron
filings, and from contamination of dirt and bacteria which is
present on floors and is indirectly transferred from the mop to
users' hands or nail seams. If users do not clean their hands after
wringing out of mop, there is a risk of getting illness.
[0006] In view of the abovementioned disadvantages, the inventor of
the present invention has proposed the novel rotary mop of the
present invention according to the research and improvement
conducted on conventional structure and based on profound
experience in R&D and manufacturing in relevant field.
SUMMARY OF INVENTION
[0007] The present invention relates to a rotary mop, the main
object of this invention is to provide a rotary mop having simple
structure and good stability without improper shaking happened in
operation.
[0008] In order to achieve the above object, the rotary mop of the
present invention comprising:
[0009] an outer rod body;
[0010] an inner rod body arranged to be coaxial with the outer rod
body;
[0011] a transmission stem assembled in the outer rod body, the
upper end of which is attached to the outer rod body, a ratchet
block being provided on the transmission stem and one-way ratchet
teeth being formed on the bottom surface of the ratchet block;
[0012] a sleeve assembled in the inner rod body, at least two
helical grooves being formed on the inner wall surface of the
sleeve;
[0013] a drive block, having a through bore at the center for
insert-connection with the transmission stem, one-way ratchet teeth
being formed on the upper surface of the drive block for engaging

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
[0025] The objects, the technical contents and the expected effect
of the present invention will become more apparent from the
detailed description of the preferred embodiments in conjunction
with the accompanying drawings.
[0026] Referring to FIGS. 1 and 2, the rotary mop of the present
invention is formed by an outer rod body (1), an inner rod body
(2), a transmission stem (3), a sleeve (4), a drive block (5), a
lock member (6) and a mop section (7).
[0027] The outer rod body (1) is a hollow rod body, a stationary
block (12) being assembled on the upper end of the hollow portion
(11) of outer rod body (1).
[0028] The inner rod body (2) is a hollow rod body which is
inserted within the hollow portion (11) of the outer rod body (1)
to be coaxial therewith, a plug block (22) being assembled in the
hollow portion (21) of inner rod body (2) and a through bore (221)
being provided at the center of the plug block (22) for traversing
of the transmission stem (3).
[0029] The transmission stem (3) is assembled within the hollow
portion (11) of the outer rod body (1), the upper end of the
transmission stem (3) being attached to the stationary block (12)
of the outer rod body (1). A ratchet block (31) is further provided
on the transmission stem (3) and one-way ratchet teeth (32) are
formed on the bottom surface of the ratchet block (31).
[0030] The sleeve (4) is disposed within the hollow portion (41) of
the inner rod body (2), at least two helical grooves (42) being
formed on the inner peripheral wall surface thereof.
[0031] As shown in FIG. 3, the drive block (5) has a through bore
(53) provided at the center for insert-connection with the
transmission stem (3), one-way ratchet teeth (51) being formed on
the upper surface of the drive block (5) for engaging with the
one-way ratchet teeth (32) on the bottom surface of the ratchet
block (31) of the transmission stem (3). At least two guiding posts
(52) are further provided on the peripheral wall of the drive block
(5) for engaging with the two helical grooves (42) formed on the
inner wall surface of the sleeve (4). A baffle piece (33) is
attached to the bottom end of the transmission stem (3) for
limiting the drive block (5).
[0032] The lock member (6) as shown in FIG. 4 has a retaining bush
(61) inserted in the bottom edge of the outer rod body (1). A
groove (611) provided on the side of the retaining bush (61) is in
coincidence with a groove (13) provided on the side of the outer
rod body (1). Further, a press lever (62) is pivotally coupled in
the groove (611) of the retaining bush (61), and the press lever
(62) is formed with an abutment portion (621) located at the end
portion of the groove (611) for abutting firmly on the wall surface
of the inner rod body (2).
[0033] The mop section (7) as shown in FIG. 5 comprises: a coupling
rod (71) mounted on the bottom end of the sleeve (4), a disk body
(72) pivotally connected to the bottom side of the coupling rod
(71) and a mop strings (73) mounted on the bottom of the disk body
(72).
[0034] In this manner, when mop strings (73) has to be cleaned by
water and wrung out water after use, as shown in FIG. 4, the press
lever (62) of the lock member (6) is to be released from locking
firstly so that the abutment portion (621) of the press lever (62)
releases the abutment-locking on the wall surface of the inner rod
body (2). Hence, the inner rod body (2) can conduct up-down sliding
within the outer rod body (1).
[0035] Then referring to FIGS. 2 and 6, user grips the outer rod
body (1) with their hands and put the mop strings (73) into the
draining tank (81) of bucket (8) and presses the outer rod body (1)
downward, then the transmission stem (3) mounted thereon is
displaced downwardly such that the one-way ratchet teeth (32) on
the bottom surface of the ratchet block (31) of the transmission
stem (3) engage with the one-way ratchet teeth (51) on the upper
end surface of the drive block (5).
[0036] Accompanying with the downward movement of the transmission
stem (3) and the outer rod body (1), the drive block (5) engaged
with the ratchet block (31) of the transmission stem (3) also moves
downwardly. As the guiding posts (52) provided on the peripheral
wall of the drive block (5) engage in the helical groove (42)
provided on the sleeve (4), the drive block (5) will naturally move
along the helical groove (42) of the sleeve (4). At this moment,
since the drive block (5) is braked by the ratchet block (31) and
thus is unable to rotate, the sleeve (4) is rotated relative to the
drive block (5) so that the mop section assembled with the sleeve
(4) is rotated simultaneously, and the draining tank (81) is
accordingly rotated therewith. In this manner, the water contained
in the mop strings (73) can be wrung out by the centrifugal action
produced by the rotation.
[0037] In turn, as shown in FIG. 7, when user pulls the outer rod
body (1) upward, the transmission stem (3) mounted thereon is also
displaced upward such that the ratchet block (31) is disengaged
from the drive block (5). Additionally, the baffle piece (33)
provided on the bottom end of the transmission stem (3) will bring
the drive block (5) upward when the transmission stem (3) is pulled
upward. Under the state of disengagement from the ratchet block
(31), the drive block (5) is rotated in compliance with the helical
groove (42) of the sleeve (4) accompanying with upward movement. As
the sleeve (4) is immobile at this moment, the drive block (5) can
be moved to the upper end position of the sleeve (4) smoothly.
[0038] After user pulls the outer rod body (1), the transmission
stem (3) and the drive block (5) upward back to their original
positions, the outer rod body (1) is pressed down, the ratchet
block (31) of the transmission stem (3) again engages with the
drive block (5) and thus are moved downward with the outer rod body
(1) and the transmission stem (3). The drive block (5) moves in
compliance with the helical groove (42) on the sleeve (4) and thus
rotates the sleeve (4) such that the mop section (7) mounted on the
bottom end of the sleeve (4) is again rotated to wring out the
water contained in the mop strings (73) by the centrifugal action
produced by the rotation.
[0039] In this manner, by repeating the pressing downward and
pulling upward actions of the outer rod body (1), draining effect
of the water adhered in the mop strings (73) can be achieved.
Moreover, as the guiding posts (52) of the drive block (5) maintain
its engagement in the helical groove (42) provided on the
peripheral wall of the sleeve (4) throughout the process, the
rotation of the sleeve (4) can be kept in good stability so as to
avoid improper shaking happened in operation.
[0040] When a force is applied to pull the press lever (62) of the
lock member (6) into lock position, the abutment portion (621) on
the end portion of the press lever (62) will abut firmly on the
wall surface of the inner rod body (2) so as to become immovable
state between the inner rod body (2) and the outer rod body (1), as
shown in FIG. 8. In this manner, user can utilize the mop to clean
floor.
[0041] Referring to FIG. 9, an alternative embodiment of the
present invention is shown, in which the helical grooves (42) of
the sleeve (4) are formed to be projected from the inner peripheral
wall surface to the outer peripheral wall surface thereof.
[0042] Based on the foregoing element constitution and embodiment
description, the rotary mop of the present invention has the
advantages set forth below when comparing with prior art.
[0043] 1. In the present invention, the sleeve for actuating the
mop section to rotate is formed with helical grooves on its
peripheral wall and guiding posts provided on a drive block is
engaged in the helical groove. In this manner, when the
transmission stem moves the sleeve to rotate through the drive
block, the drive block is maintained to be in constant engagement
with the peripheral wall of the sleeve throughout the process,
hence the rotation action of the sleeve can be kept in good
stability so as to avoid improper shaking happened in
operation.
[0044] 2. This invention simply is an assembly comprising an inner
and an outer rod bodies, a transmission stem, a sleeve and a drive
block such that the effect of rotating the mop section to draining
out water content can be achieved. Its structure is simple and its
assembly is easy and labor-saving so that the manufacturing cost
can be reduced effectively.
[0045] Summing up above, the embodiment of the present invention
can reach anticipated effect, and the specific configurations
disclosed herein have yet not found in the prior art of the same
category of product, even has not been opened to the public before
application.
