ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a sponge mop having a cleaning tank attached thereto so as to let the detergent in the tank flow to the sponge to enhance cleaning feature of the sponge mop.
BACKGROUND OF THE INVENTION
A conventional sponge mop is shown in FIG.
9
and generally includes a post
70
having a handle
71
connected to top section of the post
70
and an operation frame connected to a lower section of the post
70
. The operation frame includes a lever member
77
with two arms
78
connected to the post
70
, and two links
76
pivotably connected to the two arms
78
. A squeezing assembly
72
includes three pairs of rollers
74
and a sponge
75
has its a ridge
73
on a top of the sponge
75
so that the ridge
73
is located between the three pairs of rollers
74
. The two links
76
extend through the squeezing assembly
72
and are fixedly connected to the ridge
73
. When pulling the lever member
77
upward, the two links
76
will lift the sponge
75
to be squeezed between the rollers
74
so that the contaminated water absorbed in the sponge
75
is squeezed out from the sponge
75
. Nevertheless, the user always uses detergent to remove the dirty portion on the ground or the floor before using the sponge mop. In other words, most of the dirty portion cannot be removed by simply using water so that the users have to take two separate actions and use different tools to deal with the dirty portions.
The present invention intends to provide a sponge mop that has a cleaning tank connected thereto and the detergent in the tank is easily operated to flow into the sponge by operating a lever handle on the tank to enhance cleaning feature.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a sponge mop and comprising a post having a first end extending through a top of a frame. The frame has two extensions and each extension has a roller connected thereto. A ridge extends from a top of the sponge and is movably located between the two extensions of the frame. A hole is defined through a top of the frame. A lever handle is pivotally connected to the post and a link is fixedly connected between the lever handle and the ridge. A tank is connected to the post and has an outlet extending from a lower end of the tank. The outlet is engaged with the hole in the frame and a seal member is removably engaged with the outlet. A top hole is defined in a top of the tank and a control assembly is received in the tank. A lower end of the control assembly is connected to the seal member and an operation handle is on a top of the control assembly which is engaged with the top hole.
The object of the present invention is to provide a sponge mop with a detergent tank connected to the post of the sponge mop so that the detergent in the tank flows to the sponge.
