ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to mop that has a detergent tank connected to the rod of the mop and a detergent feeding mechanism is controlled by rotating a collar located close to the handle of the rod.
BACKGROUND OF THE INVENTION
A conventional mop
10
is shown in FIG.
1
and includes a rod
11
which is extends through a frame
12
and fixed to a sponge
14
. Two squeeze rollers
121
are mounted to pins extending from two sides of the frame
12
and located on a top of the sponge
14
. A pull device
13
includes two links
132
pivotally connected to two plates
133
connected to the rod
11
and a pull handle
131
. The two links
132
extend through the frame
12
and fixed to the sponge
14
so that when pulling the pull handle
131
upward, the two links
132
lift the sponge
14
which is then squeezed by the rollers
121
so as to remove liquid in the sponge
14
. The uses have to add detergent before using the mop
10
to clean the floor or the like. In other words, the users have to prepare two items, the mop
10
and the detergent to complete a cleaning work.
FIGS. 2 and 3
show a mop
20
that has a tank
25
for receiving detergent therein. A valve
26
is connected between the tank
25
and a passage
224
defined in the frame
22
so as to provide detergent to the sponge
24
via a hole
241
in the sponge
24
. The frame
22
includes an opening
223
for engagement with the valve
26
. The sponge
24
is connected to a pull device
23
which includes two links
233
fixed to the sponge
24
, a pull handle
232
which is pivotably connected to the rod
21
by two plates
231
. The sponge
24
can be squeezed by pulling the pull handle
232
to allow the rollers
221
to squeeze the sponge
24
. The users have to bow down to operate the valve
26
whenever to open the valve
26
or close the valve
26
. The tank
25
is attached to a side of the rod
21
so that the appearance of the whole assembly is bulky and dumb. Besides, the tank
25
projects out from a side of the rod
21
is easily by hit or damaged by foreign objects.
The present invention intends to provide a mop that has a tank through which the rod extends, and a detergent feeding mechanism is used to control a valve to allow the detergent to flow to the sponge, wherein a collar that controls the valve is located close to the handle of the rod so that the user can easily operate the collar.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a cleaning tool which comprises a hollow rod having an aperture defined through the wall of the rod and located close to a lower open end of the rod. The rod is connected to a cleaning member by a universal member and a passage is defined through the universal member and communicates with lower open end of the rod.
A tank has a first fitting on a top of the tank and a second fitting on a bottom of the tank. The lower open end of the rod extends through the tank via the first fitting and the second fitting. The aperture in the rod is located in the tank.
A detergent feeding mechanism includes a collar which is rotatably mounted to the rod and located close to a handle portion of the rod. A movable member is engaged with the collar and movable along the rod by rotating the collar. A guide member is received in the rod and has a head which is fixed to the movable member. A valve body is secured in the rod and the guide member movably extends through the valve body. A chamber is defined in the valve body and an end member on the guide member is movably received in the chamber. A side hole is defined through a wall of the valve body and communicates with the chamber of the valve body and the aperture in the rod. An end member is connected to the guide member and disengageably seals a lower open end of the valve body.
