In the drawings:
The invention relates generally to invention liquid dispenser with interchangeable head and operating mechanism for remotely applying a liquid to a surface utilizing a dispenser with a dispenser head at the distal end. The dispenser device has an elongated handle and liquid is delivered to the dispenser head utilizing a remote operating mechanism to activate pump.
The dispensing head may be a mop pad head, a liquid dispensing unit, a liquid dispensing squeegee, a liquid dispensing mop unit, a paint roller unit, a paint pad unit, a brush unit, or combinations thereof. The dispensing head includes a liquid dispensing manifold.
The device includes an elongated handle in which the handle may be one piece, telescoping, or separate sections that are removable. When there are separate removable sections, the sections have a male connection at a top end and a female connection at a bottom end of each section.
The pumping mechanism operates under at least one pump which is under processor control. There is a mechanism for activating the pump including on/off, forward liquid movement into the dispensing head and reverse liquid movement into the liquid reservoir. A transmitter and receiver control movement of the pump motor.
Referring now in detail to the drawings wherein like reference numerals designate corresponding parts throughout the several views, various embodiments of the present invention are shown.
The liquid dispenser with an interchangeable head and remote operating mechanism 1 includes an elongated handle member 3, a liquid reservoir 11, fluid conduit 15, a universal head connector 13, a pump 21, at least one remote control means 45,47 and at least one interchangeable head 37, in this case a mop head. The elongated handle member 3 has a proximal end 5 with a handle 43 for a user to hold, and an opposing distal end 7. The distal end 7 includes a storage compartment 9.
The elongated handle member 3 may be a telescopic handle member, separate sections, or one piece. The elongated handle member 3 may be six inches to one foot, but is preferably at least three feet. However, it may be eight or ten feet. The liquid reservoir 11 is contained within the storage compartment 9.
The fluid conduit 15 is connected at a first end 17 to the liquid reservoir 11 and connected at a second end 19 to a universal head connector 13. The universal head connector 13 is located at the second end 19 of the fluid conduit 15 and has external exposure at the distal end for connection to at least one interchangeable head 37. The at least one interchangeable head 37 is connectable to the universal head connector 13. In this case the interchangeable head is a mop pad head, but it may be a liquid dispensing unit, a liquid dispensing squeegee, a liquid dispensing mop unit, a paint roller unit, a paint pad unit, a brush unit, or combinations thereof. The mop pad head includes a liquid dispensing manifold 41 and a rigid head tube 35 connected to the mop head member at one end and connected to the universal head connector at the other end. The connections are made through threading. The mop rigid head tube 35 includes a fluid conduit inside the rigid head tube. The liquid dispensing manifold 41 includes at least one aperture for dispensing the liquid.
The pump 21 is located in the storage compartment 9 and is functionally connected to the fluid conduit 15. The pump 21 includes a motor, power source and controller, collectively shown as unit 23. In addition, a remote control wireless receiver 25 is functionally connected to the motor, power source and controller, collectively shown as unit 23. The motor may be a battery operated electric motor, in which case, the storage compartment includes battery holding means and connection means to at least one of the electric motor 23, and the remote control means 45, 47. The remote control means 45, 47 may be connected by wire connection or by wireless connection to the electric motor 23 through a motor, power source transmitter and power source, collectively shown as unit 49.
The remote control means 45,47 is located near the proximal end 5 of the elongated handle member 3. Remote control means 45 is a directional switch for forward and reverse pumping for operating the pump in a first direction to pump liquid into the liquid reservoir 11 and in a second direction for subsequently pumping out of the liquid reservoir 11.
There are optional manual overrides for a forward pump button 27, a reverse pump button 29, and an on/off button 31. When the elongated handle member 3 is eight feet long, for example, it would be easier to use the manual override buttons.
There is an inlet valve 50 including a one-way valve for refilling the liquid reservoir 11. The inlet valve 50 extends into the fluid conduit 15 which exits into the liquid reservoir 11. The inlet valve 50 is located within the storage compartment 9 and is connected at one end to one of the fluid conduit 15 and the liquid reservoir 11. The inlet valve 50 is connected at an opposite end to an external area of the storage compartment 9. Furthermore, the inlet one-way valve permits liquid to flow into the reservoir 11 and prevents liquid from flowing out of the inlet valve 50 to provide a fill inlet separate from the universal head connector 13.
In operation, the liquid reservoir 11 is first filled with liquid and the handle member is extended or shortened, if it is not a single segment. The power button 47 is turned on and the directional switch 45 for dispensing is held down to remotely operate the pump in a forward direction. Forward pumping out of the liquid reservoir is selected. The transmitter 49 sends signals to the remote control wireless receiver 25 to operate the pump 21 via unit 23. The pump 21 pumps liquid out of the liquid reservoir 11 through the fluid conduit 15 which flows into the fluid conduit 39 and out through the liquid dispensing manifold 41. The liquid being dispensed may be a cleaner, water, paint or any other liquid and mop pad head 37 could be any of the appropriate interchangeable heads described above and below.
When a user needs to stop the flow of liquid out of the liquid reservoir, the power button 47 is moved to off. Through the transmitter and the receiver, the flow of the liquid is stopped. When a user needs to move liquid into the liquid reservoir 11, the directional switch (not shown because it is behind forward directional switch 45 show in the Figure) is pressed to reverse flow of liquid into the liquid reservoir 11. Of course, the optional manual override buttons may also be employed to perform the operational functions.
There are many ways for filling the liquid reservoir 11. A hose and gravity feed may be employed by using inlet valve 50. Other means for filling the liquid reservoir include the use of an external pump, prefilled liquid resevoirs that are inserted through an opening in the storage compartment having fastening means, inserting a universal stopper into the liquid reservoir connected to a liquid source and activating reverse flow of liquid, filling a camelback bag unit or any other means for moving liquid from one source to another or collecting liquid in a liquid reservoir.
With reference to box 63, the remote control means is located near the proximal end of the handle member for turning the pump on and off. Furthermore, the remote control means is and for operating the pump in a first direction to pump liquid into the liquid supply container and in a second direction for subsequently pumping out of the liquid supply container.
