Definitions

  • the automatic flushing device for a flush toilet in the present invention comprising a water tank, a case for fixing a coil in the water tank and under a tank lid, a round iron block set inside the coil, and a shaft tube connected at its upper end with a round block and at the lower end with a rhonboidal ball, an infrared sensor, and an electronic circuit as the main components.
  • the water tank has a rubber gasket placed on its upper edge and then a tank lid covers the tank.
  • Four hangers having a threaded hole hang inwardly on the upper edge of the tank for supporting the case for fixing a coil in the tank.
  • the case for fixing the coil is shaped rectangular, having two threaded holes in both length-with opposite side walls for two pairs of threaded rods to screw through to screw with a female-threaded tube placed between each pair of the opposite holes in the side walls.
  • the two female-threaded tubes respectively have an opposite-direction thread at the right and the left section such that rotation of the female-threaded tubes can make two pairs of the two threaded rods screw in or out.
  • those threaded rods have their outer end screw with holes in the four hangers so that the case can be supported firmly in its place by the four threaded rods and the four hangers.
  • the case is also provided with a cylindrical base in its interior for fixing the coil therein, a spring and the round iron block inside the coil.
  • the round block placed under the spring has a threaded rod extending through a hole in the bottom wall of the case, possible to move up magnetically when the coil is energized by the electronic circuit.
  • the spring urges the bottom surface of a cap covering the case and thus can be shrink up when the round block is pulled up by the coil while energized and can push elastically down the round block when coil is de-energized.
  • the shaft tube has at the upper end a female thread to screw with the bottom end of the threaded rod of the round block and at the bottom end a male thread to screw with a rhonboidal ball normally blocking an outlet of the tank. Therefore, the rhonboidal ball can be moved up together with the round block, leaving the outlet, through which the water in the tank can be flushed in the toilet, when the coil is energized.
  • the infrared sensor can sense if a person uses the toilet and the electronic circuit can count the period of time it is used and judging according to three periods of time, less than 10 seconds, 10-120 seconds, and more than 120 seconds, to energize the coil 24 respectively for 1 - 2 seconds or 3 - 5 seconds or 5 - 10 seconds to pull up the rhonboidal ball, and thus to flush water for the same length of time.
  • Figure 1 is an exploded perspective view of the automatic flushing device for a flush toilet in the present invention.
  • Figure 2 is an elevational view of the automatic flushing device for a flush toilet in the present invention.
  • Figure 3 is a diagram of the electronic circuit for controlling the automatic flushing device in the present invention.
  • Figure 4 is a first actional view of the automatic flushing device in the present invention.
  • Figure 5 is a second actional view of the automatic flushing device in the present invention.
  • a tank 1 combined with this automatic flushing device has the same structure as a conventional tank for storing water and a float in controlling the level of the water therein.
  • the automatic flushing device in accordance with the present invention is to be described as follows.
  • the automatic flushing device comprises a rubber gasket 12 on the circumferential edge of the tank 1 to enable a tank lid 11 to cover tightly the tank 1.
  • Four hangers 16 are hooked on the upper edge of the tank 1, having a threaded hole 161 for a threaded rod 23 to horizontally screw with so that a case 2 can be supported at its place firmly by the four rods 23 in the upper interior of the tank 1 under the tank lid 11.
  • the case 2 has two opposite threaded holes 21 in both the lengthwise side walls and two female-threaded tubes 22 having an opposite-direction female thread at the right and the left section are respectively placed between the two opposite threaded holes 21 and screwed with the four threaded rods 23 at the same time by rotating the two tubes 22, and the four rods 23 can screwingly advance in or retreat out of the said tubes 22 by the rotation of said tubes 22.
  • a rectangular rubber gasket 26 is fixed on the upper circumferential edge of the case 2 to tighten connection of the case 2 with the bottom surface of the tank lid 11.
  • the case 2 is provided with a cylindrical base 27 in its interior, and the cylindrical base 27 has a round hole 28 in its bottom wall and a cap 29 covering its top by screwing.
  • a coil 24, a spring 25 and a round iron block 31 are placed in the cylindrical base 27, and the spring 25 is confined inside the coil 24 under the cap and on the round block elastically urging the cap 29.
  • the round block 31 has its bottom welded with a threaded rod 32 passing through the round hole 28 downward and screwing with a shaft tube 3 having its bottom end screwed with a rhonboidal ball 35, which conforms to an outlet 4 and thereby functions to stop or let out the water in the tank 1.
  • the shaft tube 3 can move up and down with the round block 31, limited by a position round hole 41 it passes through, having a hollow interior and sidewise holes 34 at its upper section, through which the water in the tank 1 can flow down to the outlet 4 when the tank 1 is full of water too much. Thus the water can never overflow the upper edge of the tank 1.
  • the shaft tube 3 is also provided with at its lower section an ear hole 36 tied with one end of a string having its other end tied with a lever 14 connected with a push handle 13 fixed at the outside wall fo the tank 1 so that the push handle 13 can be manually operated to flush the water, as shown in Figs. 4 and 5.
  • An electronic circuit for controlling the automatic flushing device is shown in a diagram in Fig. 3, kept in a control box 5 and connected with the coil 4 so as to control the length of time for pulling up the round block 31 together with the shaft tube 3 and thus adjusting the volume of the water to be flushed in three stages.
  • the function of the electronic circuit is to be described as follows:
  • the coil 24 cannot be energized unless a person comes near the toilet more than 10 seconds.
  • the water is to be flushed 1 - 2 seconds in case of using the toilet more than 10 seconds, to be flushed for 3 - 5 seconds in case of 11 - 120 seconds of using the toilet, and to be flushed for 5 - 10 seconds in case of more than 120 seconds.
