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;

a handle connected to the brush head;

a reservoir in the handle for containing a liquid cleaner;

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

a trigger for actuating the mechanism through mechanical force provided by a user; and

a mesh for aerating the liquid cleaner with the ambient air into a foam at the cleaning bristles through the mechanical force provided by the user.

2. The apparatus of claim 1, wherein the mechanism is a valve.

3. The apparatus of claim 1, wherein the mechanism is a pump.

4. The apparatus of claim 1, wherein the mechanism moves with respect to the handle under the mechanical force provided by the user.

5. The apparatus of claim 1, wherein the mechanism comprises a foam pump, the foam pump moving with respect to the handle under the mechanical force provided by the user through the trigger.

6. The apparatus of claim 5, further comprising a coiled tube to maintain the foam pump in fluid communication with the reservoir when the foam pump is moving.

7. The apparatus of claim 1, wherein the reservoir moves with respect to the handle to actuate the mechanism, the reservoir moving under the mechanical force provided by the user through the trigger.

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

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

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

11. A hand pump cleaning brush, comprising:

a brush head with cleaning bristles;

a handle connected to the brush head;

a reservoir in the handle for containing a liquid cleaner;

a valve for mechanically mixing ambient air and the liquid cleaner from the reservoir into a foam; and

a trigger for powering the valve through mechanical force provided by a user.

12. The hand pump cleaning brush of claim 11, wherein the valve moves with respect to the handle under the mechanical force provided by the user.

13. The hand pump cleaning brush of claim 11, wherein the reservoir moves a part of the valve with respect to the handle under the mechanical force provided by the user.
