At least a portion of the releasing mechanism may extend out of the tank through a second opening located substantially opposing the first opening. The first opening may be located adjacent a channel so that upon disengagement of the removable valve disc from the valve seat, at least a portion of the contents of the tank may travel through the valve seat and first opening and into the channel portion.

(9) As shown for example in FIG. 1, the illustrated device 10 includes a tank 12, a releasing mechanism 14 including a connector portion 16 and an arm portion 18, and a channel 20. The channel 20 may include a rigid portion 22 and/or a flexible portion 24. The channel may include a terminal end 26 located adjacent the flexible portion 24. The terminal end 26 may include a protective halo 28 and may also be substantially rigid. A first opening 30 may be located in a wall 32 of the tank 12. At least a portion of the connector portion 16 may be located within the tank 12, while a portion of the connector portion 16 may be located outside the tank 12. The arm portion 18 may be attached to the connector portion 16 via a fastening mechanism 34 while the arm portion 18 is located substantially external to the tank 12. A spring 36 may be attached to the arm portion 18 and the tank 12 to assist in movement of the releasing mechanism 14. The tank 12 may include a second opening 38 through which the connector portion 16 of the releasing mechanism 14 enters the tank 12. The second opening 38 may include a cover 40 having an aperture 42 located thereon. The aperture 42 may also be located anywhere on the tank 12 at point where the releasing mechanism 14 is still functional. The connector portion 16 of the releasing mechanism 14 may enter the tank 12 through the aperture 42. The tank may include a third opening 44 which may be capable of connection to an additional hose. The device may be located onto a stand 46 so that the first opening 30 lies above any item (e.g., a toilet) that requires flushing or cleaning. The stand 46 may be located onto one or more wheels 48 to allow for simplified movement of the device between locations. In further embodiments of the invention the arm portion 18 may be any other means of opening a valve such as a handle, a button, a peddle or any other means known in the art.

(10) FIG. 2A depicts a device in accordance with the present teachings in use for purposes of toilet cleansing. The device is shown containing a liquid 50 within the tank 12, prior to the release of any liquid 50 through the first opening 30 and into the channel 20. The liquid may be provided to the tank from any water source, which may include grey water tanks present at large care facilities. The terminal end 26 of the channel 20 is placed into a toilet bowl 52 so that the protective halo 28 rests on the seat portion 54 of the toilet.

(11) FIG. 2B depicts the connector portion 16 of the releasing mechanism 14 is fastened to the removable valve disc 56. The figure further illustrates a valve body 58 that is shaped to form a friction fit with the first opening 30. A removable valve disc 56 and a valve seat 60 makes up the valve body 58. The removable valve disc 56 may be attached to the connector portion 16 of the releasing mechanism 14. The valve seat 60 may be located within the first opening 30. As shown at 2B.

(12) In another embodiment the seat portion 54 is first lifted up and terminal end 26 of the channel 20 is then placed into the toilet bowl 52, so that the protective halo 28 rests directly on the toilet rim 62 preventing any spills that would otherwise occur between the seat portion 54 and the toilet rim 62.

(13) FIGS. 3A and 3B show the device of FIGS. 2A and 2B upon release of the liquid 50 through the first opening 30 and into the channel 20. To allow the liquid 50 to move through the first opening 30, the removable valve disc 56 must be disengaged from the first opening 30. To do so, a user may exert downward pressure onto the arm portion 18 of the releasing mechanism 14. This may cause the connector portion 16 to be pulled in the respective direction of the releasing mechanism which in turns pulls upward on the removable valve disc 56 to dislodge the removable valve disc 56 from engagement with the valve seat 60. This allows the liquid 50 of the tank 12 to flow into the valve seat 60. The liquid 50 may then travel through the first opening 30, into the channel 20 and into the toilet bowl 52 so that the force of the liquid causes any contents of the toilet bowl to be flushed. The spring 36 may exert a force upon the arm portion 18 of the releasing mechanism 14 so that the connector portion 16 of the releasing mechanism 14 may be able to return to its original position within the tank after the necessary liquid exits the tank.

(14) In another embodiment of this invention the removable valve disc 56 may be hinged to the valve seat 60. Whereupon disengagement of the removable valve disc 56, the liquid 50 of the tank 12 may flow to into the valve seat 60, and then travel through the first opening 30, into the channel 20 and into the toilet bowl 52 so that the force of the liquid causes any contents of the toilet bowl to be flushed. In this embodiment the removable valve disc 56 remains only partially engaged to the valve seat 60 for the deration of time that one exerts pressure on the arm portion 18 of the releasing mechanism 14. In other embodiments of the invention, the amount of pressure required to be exerted on the arm portion 18, of the releasing mechanism 14 and the direction in which it is exerted is determined by the valve opening means used.

(15) FIG. 4 shows another embodiment of the releasing mechanism. In this embodiment the function of the releasing mechanism may further be modified by moving the arm portion to the wall 32 of the tank 12 above the first opening 30 and having the connector portion pass through the valve body 58 and attach to the removable valve disc 56. FIG. 4 further illustrates that in some embodiments the arm portion 18 may not require the application of constant pressure while the liquid 50 is released from the tank 12, for example the connector portion 16 may be a helical thread 64 which requires one to turn the arm portion 18 to disengage the removable valve disc 56 from the valve seat 60. valve the constant may not be required while in others

(16) The function of the releasing mechanism may further be modified by use of a solenoid valve (not shown) with a power source. The solenoid valve may eliminate the need for the releasing mechanism as disclosed above such that the removable valve disc can be automatically actuated without need for manual force, such as that required to utilized the releasing mechanism.

(17) FIG. 5 shows an exploded view including illustrative examples of elements that may be present in the device in accordance with the present teachings. The tank 12 may include one or more openings including but not limited to a first opening 30, a second opening 38, and a third opening 44. The third opening 44 may be adapted for attachment to a hose (not shown) so that any liquid (not shown) in the tank 12 may be accessed via the hose. A releasing mechanism 14 may be located into and/or adjacent to the tank 12. The releasing mechanism may include a connector portion 16 for connecting the releasing mechanism to a removable valve disc 56, and an arm portion 18. A first end 66 of the connector portion 16 may be attached to a first end 68 of the arm portion. A user may contact a second end 70 of the arm portion 18 to exert a downward force on the arm portion 18 so that the contents of the tank may be released through the first opening 30. A second end 72 of the connector portion 16 may have an attachment means (not shown) for connecting the connector portion 16 to the removable valve disc 56.

(18) The second opening 38 of the tank may be at least partially contacted by a cover 40. The cover 40 may include an aperture 42 through which the connector portion 16 of the releasing mechanism 14 may be located within the tank 12. The cover 40 may also include one or more additional openings (not visible) which may include one or more caps 74 for covering any additional openings.

(19) The valve seat 60 may be placed in the bottom of the tank 12 so that the first opening 30 and the bottom of the valve seat 76 form a continuous opening for any liquid (not shown) to exit the tank 12 into the channel 20 when the removable valve disc 56 is disengaged from the valve seat. The first opening 30 of the tank may be connected to a channel 20. The channel may include a first rigid portion 78 which may be in direct contact with the first opening 30 of the tank. The channel may include at least one flexible portion 24 which may be located in between the first rigid portion 78 and a second rigid portion 80. The second rigid portion 80 may include a protective halo 28 for minimizing unwanted splashing during use. The second rigid portion may also include an attachment means such as a loop 82 so that the channel 20 may be attached to the tank 12 when not in use or while moving the device from one location to a second location. As such, the tank may include an external attachment means such as a hook 84 for receiving the loop 82 of the channel 20.

(20) The device may be located onto a stand 46 so that the tank 12 is positioned at a height wherein the first opening 30 of the tank lies above the height of any item being cleansed. The stand 46 may include a platform 86 which may be adapted with a means for moving the device from one location to another, such as one or more wheels 48. The platform may include a drawer 88 or any storage structure for holding additional cleaning materials or additional components of the device. As an example, the drawer may be adapted to hold a power source for powering the device or a portion of the device if desired. The power source may provide a means for forcing tank contents into and from a hose that may be attached to one or more of the tank openings.

(21) In another embodiment of the invention the channel may be lowered and raised electronically, removing the need for someone to contact the second rigid end. The invention may further be modified so that the tank may be placed directly over the toilet, the terminal end with or without the protective halo may be placed into the toilet allowing flushing of toilets in narrow areas. The channel may be modified so that it can expand for use and then be contracted again for storage. The stand may be modified to be height adjustable so allow it to be raised in lowered over toilets. The stand and/or platform may be modified to include one or more feet. The stand and/or platform may further be modified to add a motor and becoming motorized.

(22) The terminal end may be modified to include a sensor. The sensor in the terminal end may be connected to a light and/or a buzzer that can alert the user that the toilet is not flushing and is likely to overflow. The sensor could also lead to the stoppage of the flow of water. In one embodiment the terminal end is equipped with a closing means which stops the flow of water at the terminal end. The sensor could cause the water flow to stop by either closing the valve or by activating the closing means.

(23) The device may include a spray device that is capable of receiving and expelling water from within the tank. The spray device may include a pump for moving water from the tank through and out of the spray device. The spray device may be used for cleaning and/or rinsing any portion of a toilet during the flush process.
