Functioning

[0047] The present invention describes a device or an attachment which can be fitted to pipe for automatic flushing of the urinal-toilet. According to the disclosure and FIG. 1, 2, 3 provided, it can be described as an automatic toilet flushing device with a spring actuated platform by virtue of the weight load/pressure of the user and ensuring a regular, compulsory and un-intentional flushing of the Urinal-Toilet. In the normal condition the inlet Dual-valve 1 is in the closed position and the outlet Dual-Valve 2 is in the open position. The motion of both the valves is in synchronization with each other, i.e. when one valve closes the other opens and vice-versa.

[0048] The Mechanical Platform 10 compresses under the weight of a person when a person stands on it. This movement of the platform activates the spring mechanism. The compression spring 9 gets compressed up to the pre-decided/pre-set movement, as restricted by the Movement Restrictor 11. The downward motion of the platform 10 pulls the Cable 8 creating a tension in the Tension Spring 7 and thereby displacing the Dual-valves 1 and 2 from their normal positions. The downward motion causes the inlet Dual-Valve 1 to open and outlet Dual-Valve 2 to close simultaneously. When the inlet Dual-valve 1 opens, the water fills in the Temporary Reservoir 5 from the water pipe. After the person leaves the Platform 10, the Compression Springs 9 decompresses and the platform 10 rises back to its normal state. During the upward rise of the platform 10 the tension in the Tension Spring 7 releases due to which the inlet Dual-Valve 1 closes and outlet Dual-Valve 2 opens i.e. the valves regain their normal position. This opening of outlet Dual-Valve 2 flushes the water to the urinal-toilet.

[0049] The present invention discloses an automatic flusher with dual-valve pipe mechanism actuated by a mechanical platform which utilizes the weight or pressure of the person using the urinal-toilet for automatic flushing the urinal or toilet with the specified or measured quantity of water. The pipe consists of bulged portion acting as a temporary water reservoir with the cross section of inlet and outlet of the pipe in conformance with the shape mutually connected inlet and outlet specially designed float-valve fitted flushers system normally closed for automatically holding and releasing the specific or measured quantity of water in to the urinal after use. These floats move simultaneously to control the flow of water in to or out of the temporary water reservoir in response to the use of spring fitted platform for automatic flushing of water in urinal.

[0050] The search and analysis study revealed that both of the closest cited documents (U.S. Pat. No. 4,007,499A and DE462517A) disclose automatic float valve type toilet flusher but none of them reveal the technology used for controlling the flow and drainage of water by using dual-valve pipe mechanism as disclosed in present invention. Also, no prior art document has been retrieved which mentioned the use of a device or an attachment which can be connected in line with the pipe through which water flows into the urinal-toilet.

[0051] The flush is operated by the spring fitted mechanical platform without the use of any laser or infrared sensor or any other electrical of electronic device. The construction is simple, low cost and easy.

Advantages

[0052] The main advantages of the invention are: [0053] No need for manual knob/trigger pushing or electronic/electrical operation. [0054] Low cost and cheaper. [0055] Simple and easy to construct and can also be retrofitted to existing urinals-toilets with some modification. [0056] Easy and Low Maintenance. [0057] Maintenance cost is negligible. [0058] Operation is automatic and without any intention/efforts. [0059] No wastage of water. [0060] Leads to regular and compulsory flushing and cleaning of toilets/urinals. [0061] Assured regular flushing.
