The guiding member 100 is formed in an elongated and hollow structure, wherein the guiding member 100 has an air passage 102 defined between an upper end 104 and a bottom end 106. In the presently first embodiment, the guiding member 100 is a flexible and stretchable air tube forming the air passage 102 within an interior of the guiding member 100. The guiding member 100 is made of rubber or other air-sealed flexible material.

The inflatable water stopper 200 is extended from the bottom end 106 of the guiding member 100, wherein the inflatable water stopper 200 is designed for positioning in the bottom drain 12 of the toilet bowl 10 to provide a water sealing effect thereat. In the presently first embodiment, the inflatable water stopper 200 comprises an inflatable bladder 202 integrated with the bottom end 106 of the guiding member 100. The interior of the inflatable bladder 202 communicates with the air passage 102 of the guiding member 100 to let the air pumping into the inflatable bladder 202 through the air passage 102 and to let the air releasing from the inflatable bladder 202 through the air passage 102. The wall of the inflatable bladder 202 is thinner than the wall of the guiding member 100. Therefore, only the inflatable bladder 202 is inflated.

The pump device 300 is provided at the upper end 104 of the guiding member 100. In the presently first embodiment, the pump device 300 is coupled at the upper end 104 of the guiding member 100 and the pump device 300 cannot be detached from the guiding member 100. It is preferred that the pump device 300 is affixed to the guiding member 100 by a clamp. The pump device 300 comprises a hand squeezable pump 302 coupled at the upper end 104 of the guiding member 100 and an air releasable valve 304 provided at the guiding member 100. When the hand squeezable pump 302 of the pump device 300 is actuated, air is pumped into the inflatable bladder 202 through the air passage 102 of the guiding member 100 to inflate the inflatable bladder 202. The hand squeezable pump 302 is actuated to pump the air at one single direction to the inflatable bladder 202. When inflating the inflatable bladder 202, the air releasable valve 304 is actuated at its closed position. To deflate the inflatable bladder 202, the air releasable valve 304 is actuated at its opened position.

The inflatable bladder 202 of the inflatable water stopper 200 is inflated at a predetermined size for matching with a size of the bottom drain 12 of the toilet bowl 10 to water-seal thereat and for raising water level in the toilet bowl 10 when water is added. The inflatable bladder 202 can be stopped being inflated at any time when the wall of the inflatable bladder 202 is sealed at the wall of the bottom drain 12 of the toilet bowl 10 by the air pressure within the inflatable bladder 202. The inflatable bladder 202 will not be deflated unless the air releasable valve 304 is actuated at its opened position. The inflatable bladder 202 will also be self-deformed to match the shape and size of the bottom drain 12 of the toilet bowl 10 to provide the water sealing effect thereof.

The inflatable bladder 202 can be positioned at the drain opening 14 of the toilet bowl 10 or the drain channel 16 thereof. The size of the drain opening 14 should be larger the size of drain channel 16. However, the inflatable bladder 202 can be inflated at different sizes to match with the size of the drain opening 14 or the drain channel 16. When the inflatable bladder 202 is inflated to seal at the drain opening 14 of the toilet bowl 10, the size of the inflated inflatable bladder 202 should be bigger. However, relatively less amount of water will be filled into the toilet bowl 10 to reach the upper rim thereof. When the inflatable bladder 202 is inflated to seal at the drain channel 16 of the toilet bowl 10, the size of the inflated inflatable bladder 202 should be smaller. However, relatively large amount of water will be filled into the toilet bowl 10 to reach the upper rim thereof. The position of the inflatable bladder 202 can be selected according to the preference of the user.

Since the guiding member 100 is flexible, the inflatable bladder 202 may not able to precisely position at the right location of the bottom drain 12 of the toilet bowl 10. The inflatable water stopper 200 further comprises a weighting element 204 provided at a bottom of the inflatable bladder 202 to ensure the inflatable bladder 20 being sunken to the bottom drain 12 of the toilet bowl 10. When the inflatable bladder 202 is placed in the toilet bowl 10, the weighting element 204 will apply the downward force to the inflatable bladder 202 to force the inflatable bladder 202 downwardly sliding to the bottom drain 12 of the toilet bowl 10. The user is able to pull up the guiding member 100 to adjust the position of the inflatable bladder 202 close to the drain opening 14 or to push down the guiding 100 to adjust the position of the inflatable bladder 202 toward the drain channel 16. In the presently first embodiment, the weighting element 304 is made of metal and is disposed inside the inflatable bladder 202. It should be appreciated that the weighting element 204 can be attached to the exterior bottom side of the inflatable bladder 202 to add the sinking weight of the inflatable bladder 202.

Once the inflatable bladder 202 is sealed at the bottom drain 12 of the toilet bowl 10, the water can be added, from the flushing water tank or a bucket of water, into the toilet bowl 10 to raise the water level up to the upper rim of the toilet bowl 10.

A cleanser, made of water soluble, can be added into the water for removing the stains especially the stains accumulated around the upper rim of the toilet bowl 10.

In the presently first embodiment, the toilet cleaning device further comprises a cleanser releasing container 400 provided at the guiding member 100 close to the inflatable water stopper 200 for containing the cleanser and releasing the cleanser into the water. The cleanser releasing container 400 comprises a body 402 having a cavity to receive the cleanser and a re-closable cap 404 detachably coupled with the body 402 to enclose the cavity. The body 402 has a mesh structure to release, in particularly slow release, the cleanser inside the cavity to the water. The cleanser can be in liquid form or solid form and can be refilled into the body 402 via the re-closable cap 404.

The body 402 of the cleanser releasing container 400 is made of floating material, wherein the cleanser releasing container 400 floats in the water within the toilet bowl 10 even when the cleanser is contained in the cleanser releasing container 400. Since the cleanser releasing container 400 is affixed at the guiding member 100 close to the inflatable water stopper 200, the cleanser releasing container 400 floats upward in the water toward the water level. The cleanser will float in the water to mix therewith. The floating feature of the cleanser releasing container 400 ensures the cleanser being released from the cleanser releasing container 400 and being evenly dissolved in the water. It should be appreciated that a floating element can be affixed to the body 402 to ensure the cleanser releasing container 400 floating in the water.
