Abstract

A hand pump cleaning brush is provided. In an implementation, a cleaning brush converts liquid cleaner in a reservoir to a lather of cleaning foam through mechanical action provided by the user. An example cleaning brush may include a handle connected to a removable bristle block. A liquid reservoir is contained within the handle and stores the liquid cleaner. The reservoir is connected to a piston driven pump and/or valve that produces foam, for example, by aeration with ambient air through a mesh. A finger trigger provides pumping force. In an implementation, the foaming pump or valve draws air and liquid cleaner into a chamber and dispenses these to the brush head through a fine mesh screen, which aerate the liquid cleaner into a foam at the brush head. A rotary locking device with a push button can allow the head to swivel on the handle.

Claims

1. An apparatus, comprising:

a brush head with cleaning bristles, the brush head rotatably attached to a longitudinal handle member;

the cleaning bristles mounted on the brush head in a plane non-perpendicular to a longitudinal axis of the longitudinal handle member;

the brush head rotatable about an end of the longitudinal handle member for disposing the cleaning bristles in various non-perpendicular planes with respect to the longitudinal axis of the longitudinal handle member;

a reservoir in the handle for containing a liquid cleaner;

a pump for drawing ambient air and for drawing the liquid cleaner from the reservoir;

the pump comprising

a first piston for pumping the liquid cleaner,

a second piston for pumping the ambient air, and

an outer casing;

the first piston and the second piston fixed along the longitudinal axis with respect to the longitudinal handle member and fixed to a mixing chamber;

a discharge tube having a first end rotatably attached to the mixing chamber and a second end in rotatable fluid communication with the cleaning bristles;

a trigger hinged to the longitudinal handle member and coupled to the outer casing of the pump to move the outer casing of the pump along the longitudinal axis of the longitudinal handle over the fixed first piston and the fixed second piston through mechanical force provided by a user;

a mesh at the second end of the discharge tube for aerating the liquid cleaner with the ambient air into a foam at the cleaning bristles through the mechanical force provided by the user; and

wherein the reservoir is fixed to the outer casing of the pump and moves in unison with the outer casing of the pump with respect to the fixed first piston and the fixed second piston and with respect to the longitudinal handle member to actuate the pump, the reservoir and the outer casing of the pump moving under the mechanical force provided by the user through the trigger.

2. The apparatus of claim 1, further comprising a coiled tube to maintain the outer casing of the pump in fluid communication with the reservoir when the outer casing of the pump is moving with respect to the reservoir.

3. The apparatus of claim 1, wherein the cleaning bristles are removable.

4. The apparatus of claim 1, wherein the brush head can swivel to different angles with respect to the handle.

5. The apparatus of claim 1, wherein the reservoir has a clear viewing window.

6. A waterless foaming cleaning brush with adjustable brush head, comprising:

a tubular member comprising a handle having a longitudinal axis;

a reservoir in the tubular member for containing a cleaning liquid;

a pump in the tubular member having an axial stroke displacement along the longitudinal axis of the tubular member;

a first piston of the pump for pumping a gas and having a radial diameter comparable to an inner diameter of the tubular member;

a second piston of the pump within the first piston and concentric with the first piston for pumping the cleaning liquid;

a trigger attached to an exterior of the tubular member to actuate an outer casing of the pump over the first piston and the second piston along the longitudinal axis, retracting the first piston and the second piston into the outer casing to displace a volume of the gas and the liquid cleaner within the outer casing;

a mixing chamber attached to the pump for mixing the gas with the cleaning liquid;

a discharge tube rotatably attached to the mixing chamber;

a foaming screen attached to the discharge tube;

a brush head rotatably connected to the tubular member; and

cleaning bristles rotatably disposed on the brush head at a non-perpendicular angle with respect to the longitudinal axis, the cleaning bristles in foam communication with the discharge tube.

7. The waterless foaming cleaning brush of claim 6, wherein the trigger actuates a stroke displacement of the pump along the longitudinal axis of the tubular member to produce a metered amount of a foam at the cleaning bristles.

8. The waterless foaming cleaning brush of claim 6, further comprising a spring to return the trigger and the outer casing of the pump to an initial position, wherein the first piston and the second piston are extended from the displacement within the outer casing of the pump.

9. The waterless foaming cleaning brush of claim 6 wherein at least one of the first piston and the second piston are fixed with respect to the tubular member and the trigger actuates an outer casing of the pump along the longitudinal axis to slide over the first piston and the second piston.

10. The waterless foaming cleaning brush of claim 9, wherein the reservoir is fixed with respect to the tubular member and the fixed reservoir is in liquid communication with the sliding outer casing of the pump via a coiled tube.

11. The waterless foaming cleaning brush of claim 9 wherein the reservoir is attached to the outer casing of the pump and the reservoir moves along the longitudinal axis in unison with the outer casing.

12. The waterless foaming cleaning brush of claim 6 wherein the cleaning bristles are removable and replaceable.
