[0036] The following detailed description is described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, specific details may be set forth in order to provide a thorough understanding of the subject innovation. It may be evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing the subject innovation. Moreover, the drawings may not be to scale.

[0037] The present invention is directed to a device for blocking a toilet trap that allows water to be retained above the toilet trap's water level. Referring to FIGS. 1 and 2 which shows an exemplary embodiment of the device according to the present invention. The device is having an inflatable member 1, a disc 2, a fluid conduit 3, a valve assembly 4, and a squeeze bulb 5. The wall of the inflatable member 1 can be made of elastic material that can expand on inflation. Moreover, the wall of the inflatable member 1 can be made of durable material. Since the toilet trap is a cylindrical channel, the inflatable member 1 can also be provided in a round shape. FIG. 3A-3C shows exemplary embodiments of the inflatable member being a spherical balloon shape, an oblong shape, or an oval shape. Although FIG. 3A-3C shows exemplary shapes of the inflatable member 1, a skilled person will appreciate that the inflatable member 1 can be provided in any other shape provided that it can block the toilet trap preventing the passage of water. The dimension of the inflatable member 1 can be such that when inflated, it can snugly fit into the toilet trap, wherein the fluid inside the inflatable member 1 can exert enough pressure on the walls of the inflatable member 1 to effectively block the toilet trap. The inflatable member 1 has an opening for the drawing and releasing the fluid. The fluid can be air.

[0038] Now referring to FIG. 5A-5B which shows an exemplary embodiment of the fluid conduit 3. The fluid conduit 3 can be an elongated conduit for conveying fluid. The fluid can be air or liquid. The fluid conduit 3 can have a proximal end and a distal end. The fluid conduit 3 at the proximal end can be coupled to the opening of the inflatable member 1. The distal end of the fluid conduit 3 can be coupled to a pump assembly for inflating the inflatable member 1. In one implementation, the length of the fluid conduit 3 can be such as when the inflatable member 1 is positioned into the toilet trap, the other end, i.e. the distal end extends above the toilet bowl, as can be seen in FIG. 8. In one implementation, the fluid conduit 3 can be made of plastic or metal. Moreover, the fluid conduit 3 can be flexible enough to allow adjusting the position of the inflatable member into the toilet trap. However, the fluid conduit 3 is rigid enough for not getting bowed.

[0039] Pump assembly coupled to the distal end of the fluid conduit 3 delivers fluid under pressure into the inflatable member 1 for inflation. In one implementation, the pump assembly can be an electric fluid pump. In an alternate implementation, the pump assembly can be a manual fluid pump. An embodiment of the electric fluid pump is shown in FIG. 7B which includes an outlet port for fluidly connecting to the distal end of the fluid conduit 3. Above the port can be seen is a release valve that can be used to release the pressure inside the inflatable member i.e. releasing the fluid from the inflatable member. The functioning of the release valve is known in the art. For example, the release valve can be a screw-type release valve than can be unfastened to release the fluid under pressure. The functioning of the electric fluid pump is also known in the art. The pump assembly can include a battery for powering the electric fluid pump.

[0040] The mechanical pump assembly can comprise a first valve, a second valve, a release valve, and a squeeze bulb 5. The first valve 4 is shown in FIG. 6 having an inlet and an outlet. The first valve can be a one-way valve that allows fluid to be transferred from inlet to outlet. The outlet can be coupled to the fluid conduit 3, while the inlet can be coupled to the squeeze bulb. Adjacent the outlet of the first valve can be configured a release valve for releasing the fluid under pressure from the inflatable member resulting in its deflation. An embodiment of the squeeze bulb is shown in FIG. 7A. The squeeze bulb is having an elongated resilient construction that is domed-shaped and provided with an opening that can be coupled to the first valve. The squeeze bulb can be collapsed under applied finger pressure, wherein the volume of fluid evacuates the fluid chamber under the applied pressure and transfers through the first valve into the inflatable member. Between the squeeze bulb and the first valve, the second valve can be configured, which is also a one-way valve. The second valve can be configured to allow drawing the fluid from the atmosphere into the squeeze bulb. When the applied finger pressure is released, the squeeze bulb starts to expand radially outward and returns to its original relaxed shape, resulting in the generation of air pressure within the squeeze bulb that is lower than the external ambient air pressure. The low air pressure, consequently, results in the opening of the second valve, and a volume of the fluid is drawn into the squeeze bulb. The walls of the squeeze bulb can be made of any resilient material known to a skilled person used in the manufacturing of resilient bulbs. For example, rubber is known to have good resilient properties and can be used in the manufacture of the squeeze bulb of the present invention. Alternatively, resilient plastic material can also be used. Optionally, the walls of the squeeze bulb can be reinforced with lateral ribs that also enhance gripping of the squeeze bulb.

[0041] FIG. 8 shows the device deployed into the toilet bowl, wherein the inflatable member is shown to be positioned into the toilet trap. The fluid pump assembly extends above the toilet bowl. The inflatable member can be inflated by pumping air till the inflatable member snugly fits into the toilet trap. Thereafter water can be filled into the toilet bowl up to desired level. FIG. 9 shows water filled into the toilet bowl up to the brim level. Once, the toilet bowl is filled up to the desired level, a cleaning or disinfecting agent can be added to the water. Alternatively, the cleaning or disinfecting agent can be added first, and then the water can be filled. The cleaning or disinfecting agent can also be added while the water is being filled into the toilet bowl. For example, bleach can be added for both cleaning and disinfecting the toilet bowl.

[0042] To drain the water, the inflatable member can be deflated by opening the release valve. As the inflatable member starts deflating, the block is removed and the water in the toilet bowl drains out. The device can be taken out and stored. The disc as shown in FIG. 4 is coupled between the opening of the inflatable member and the fluid conduit. The round shape disc decreases any splashing in the toilet bowl caused by deflation of the inflatable member and rushing for the water into the drainage pipe.

[0043] The present invention is a device and a method of use thereof, that allows users to clean toilets without needing a brush to scrub during the cleaning process. A user can add their desired cleaning solutions once the water level has covered all the dirty parts within the toilet bowl. The cleaning solution will then have a greater efficiency rate within the toilet bowl as it will be able to come in contact with everything that needs to be cleaned. The interior of the toilet bowl will have a finished clean look once the water is drained and flushed away. This device and method will save time and energy of the user since the cleaning process does not require the hassle of a brush and/or direct contact. The present method is hygienic comparing with the average cleaning process that uses a brush. The brush accumulates bits of waste from the toilet bowl as it scrubs, which is unsanitary and a hassle for the user. The components of the device including the inflatable member, the disc, and the fluid conduit can have a smooth surface avoiding sticking of any contaminants. The device can be easily cleaned by placing the device under running water.

[0044] While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above-described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
