ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention is related to a cleaning brush, comprising a brush embodiment, a telescopic tube, a valve assembly, a rotary connector, and a retaining sleeve wherein said brush embodiment having a threaded coupling hole disposed at the center thereof to be engaged with said telescopic tube is provided with a through groove for a scraper strip to be adapted thereto. Said valve assembly made up of a valve body, a valve sleeve and a switch sleeve is sleeve joined to one end said telescopic tube. Said rotary connector, pivotally joined to said retaining sleeve which in turn is securely fixed to a water inlet hole of said valve body thereof, can rotate freely thereon to adjust the position of a duct attached thereto, refraining said duct from twisting and winding up when said brush embodiment is moved into different angles for cleaning, and effectively saving a lot of time and efforts in cleaning thereof.
Please refer to
FIG. 1. A
conventional cleaning brush
6
is mainly made up of hollow tube
61
having a brush head
62
or sprinkler attached at the upper end and an enlarged ring flange
611
disposed at the bottom end thereof A coupling sleeve
63
equipped with an inner threaded hole
631
is sleeve joined to the bottom of said enlarged ring flange
611
for a sealing washer
64
and a switch sleeve
65
to be adapted thereto. Said switch sleeve
65
is provided with an outer threaded section
651
disposed at the upper end thereof, an inner threaded coupling hole
652
disposed at the lower section thereof, and a switch handle
653
disposed at one side thereof for controlling the discharge of water.
Please refer to FIG.
2
. In assembly, said sealing washer
64
is first located at said inner threaded hole
631
thereof and abutted against said enlarged ring flange
611
thereof. The outer threaded section
651
of said switch sleeve
65
is then screw joined to the inner threaded hole
631
of said coupling sleeve
63
, abutting tight said sealing washer
64
and said coupling sleeve
63
respectively against said enlarged ring flange
611
thereof. A sealing ring
66
is then located at the inner threaded coupling hole
652
of said switch sleeve
65
, and a coupling end of a duct
7
is screw joined to the inner threaded coupling hole
652
of said switch sleeve
65
to complete the assembly thereof.
There are some drawbacks to such conventional cleaning brush. First, although sleeve joined to said hollow tube
61
, said coupling sleeve
63
along with said sealing washer
64
is fixedly located by said switch sleeve
65
at said hollow tube
61
thereof When said brush head
62
is moved into different angles for cleaning, said coupling sleeve
63
will go therewith, unable to adjust the position of the duct
7
attached at said switch sleeve
65
thereto. Accordingly, said duct
7
is easily twisted and wound up therewith. Second, the twisted and wound-up duct
7
can uneconomically increase the efforts in cleaning due to the torsion produced therewith and inconveniently cause the interruption in cleaning for straightening out the twisted duct
7
thereof.
SUMMARY OF THE PRESENT INVENTION
It is, therefore, the primary purpose of the present invention to provide a cleaning brush, comprising a brush embodiment, a telescopic tube, a valve assembly, a rotary connector, and a retaining sleeve wherein said rotary connector, pivotally joined to said retaining sleeve which in turn is securely fixed to a water inlet hole of a valve body, can rotate freely thereon via a pivot rod of said retaining sleeve to adjust the position of a duct attached thereto, refraining said duct from twisting and winding up when said brush embodiment is moved into different angles for cleaning.
It is, therefore, the secondary purpose of the present invention to provide a cleaning brush wherein said rotary connector can straighten out the twisted duct, effectively reducing the torsion and saving a lot of time and efforts in cleaning thereof.
