The present invention relates to metal pipe cleaning. More particularly, the present invention provides a hand-held device that will clean metal piping.
There are many different jobs that will require individuals to have to clean metal piping. Metal piping traditionally needs cleaned before it is fastened together. In particular copper piping needs cleaned before it is soldered together.
Copper piping is currently cleaned by hand. This involved taking a wire brush or sandpaper and brushing the entire exterior of the pipe. This requires that the pipe be constantly rotated in order to ensure every surface is cleaned. This process can be extremely time consuming. Further, after cleaning piping for an extended period of time one may experience hand cramps of other physical pain such as carpal tunnel may result.
Consequently, there is a need for an improvement in the art of cleaning metal piping. The present invention substantially diverges in design elements from the known art while at the same time solves a problem many people face when having to clean a large number of linear feet of metal piping. In this regard the present invention substantially fulfills these needs.
The present invention provides a pipe cleaning device wherein the same can be utilized for providing convenience for the user when having to clean the exterior of metal piping. The pipe cleaning device comprises a handle member having an interior volume. The handle member is attached to a head member. The head member has an aperture located through a middle thereof, wherein the aperture is lined with a movable wire brush. The head member further contains a brush motor, wherein the brush motor circulates the brush around the interior of the aperture.
Another object of the pipe cleaning device is to provide a power source located within the handle member.
Another object of the pipe cleaning device is to provide a switch located on the handle member, wherein the switch operably couple to the brush motor.
Another object of the pipe cleaning device is to provide a handle member with an ergonomic grip.
Another object of the pipe cleaning device is to provide multiple rows of wire brushes located within the aperture of the head member.
Another object of the pipe cleaning device is to provide a head member containing a movable lever, wherein the movable lever contracts and expands the wire brush.
Another object of the pipe cleaning device is to provide a brush that expands to have a two-inch diameter.
Another object of the pipe cleaning device is to provide a brush that contracts to have a diameter of one-half inch.
Another object of the pipe cleaning device is to provide a removably attached removable head member instead of a fixed member.
Another object of the pipe cleaning device is to provide electrical contacts located on a base of the removable head member.
Another object of the pipe cleaning device is to provide electrical contacts located on a top side of the handle member.
Another object of the pipe cleaning device is to provide a collar located about the top of the handle member, wherein the collar secures to the removable head member.
Other objects, features and advantages of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.
Although the characteristic features of this invention will be particularly pointed out in the claims, the invention itself and manner in which it may be made and used may be better understood after a review of the following description, taken in connection with the accompanying drawings wherein like numeral annotations are provided throughout.
With regard to the reference numerals used, the following numbering is used throughout the drawings.
Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the pipe cleaning device. For the purposes of presenting a brief and clear description of the present invention, a preferred embodiment will be discussed as used for the pipe cleaning device.

The pipe cleaning device is further comprised of a head member 102. The head member 102 is proportioned to fit around piping. In one embodiment the head member 102 is rounded. The head member 102 has an aperture 103 located through a middle thereof. The aperture 103 has at least one brush element 104 located around the interior perimeter of the aperture 103. In one embodiment there are four rows of brush elements 104. The at least one brush element 104 has an interior gap 105 that is configured to have a pipe placed therein. The brush element 104 is connected to a brush motor as described in the description of
In the shown embodiment the at least one brush element 104 is expandable and contractable. This means that the brush element 104 will have an interior gap 105 of changeable sizes. In one embodiment the at least one brush element 104 will expand to have a maximum two-inch diameter interior gap 105. In another embodiment the at least one brush element 104 will contract to a minimum one-half inch diameter interior gap 105. In alternate embodiments other maximum and minimum diameters are used.
In the shown embodiment the head member 102 has an adjustment lever 106 located on the exterior of the head member 102. The adjustment lever 106 will rotate the at least one brush element 104 expanding or contracting the interior gap 105.
In the shown embodiment the head member 102 is permanently affixed to the handle member 101. In other embodiments the interior gap 105 has a fixed diameter. In other embodiments as described below the head member 102 is removable. In one embodiment there will be different devices having different diameter interior gaps 105.

Further, in different embodiments the handle member 101 includes a handle grip 201. In one embodiment the handle grip 201 is made from a rubber material. In another embodiment the handle grip 201 is made from a plastic material. In one embodiment the handle grip 201 has an ergonomic grip feature. This will allow the handle grip to be comfortable for the user. In the shown embodiment the ergonomic grip feature includes finger ridges 201a.
Referring now to
The removable head member 301 has a lower protrusion 302. The lower protrusion 302 is proportioned to fit within a collar member 303 of the handle member 101. The collar member 303 is attached to a top end of the handle member 101. The collar member 303 and the lower protrusion 302 will create a connection between the removable head member 301 and the handle member 101.
The lower protrusion member 302 further has electrical contacts 304 positioned thereon. The electrical contacts 304 will contact electrical contacts 305 located on the top end of the handle member 101. In one embodiment the electrical contacts 304 located on the lower protrusion member 302 are male contacts. The electrical contacts 305 on the top end of the handle member 101 are female contacts.
In the shown embodiment there are three different removable heads 301 shown. In one of the shown heads the interior gap 105z has a diameter of one-half inch. In one of the shown heads the interior gap 105y has a diameter of one inch. In one of the shown heads the interior gap 105x has a diameter of two inches.
