A flush tank includes an outlet pipe attached to a receptacle for discharging water, a float disposed close to the outlet pipe to selectively block the outlet pipe, and to control an outward flowing of the water through the outlet pipe. A magnetically forcing device may magnetically force the float to block the outlet pipe, and a detecting device may be used to detect users and to actuate the magnetically forcing device to release the float. The magnetically forcing device includes an electromagnetic device supported by a frame to act with the float. A stop may be attached to the frame to limit a movement of the float relative to the outlet pipe.

I claim: 1. A flush tank comprising: a receptacle for receiving water therein, an outlet pipe attached to said receptacle for discharging the water, a float disposed close to said outlet pipe to selectively block said outlet pipe, and to control an outward flowing of the water through said outlet pipe, and magnetically forcing means for magnetically forcing said float to block said outlet pipe, said magnetically forcing means including an electromagnetic device disposed in said receptacle for acting with said float, and said float including at least one projection extended therefrom for acting with said electromagnetic device. 2. The flush tank as claimed in claim 1 further comprising a knob attached to said receptacle, and a chain coupled between said knob and said float. 3. The flush tank as claimed in claim 1 further comprising a detecting device to detect users and to actuate said magnetically forcing means to release said float. 4. The flush tank as claimed in claim 1, wherein said magnetically forcing means includes a frame disposed in said receptacle to support said electromagnetic device, and for acting with said float. 5. The flush tank as claimed in claim 4, wherein said frame includes a casing provided therein to receive said electromagnetic device. 6. The flush tank as claimed in claim 4, wherein said frame includes at least one block provided thereon and made of magnetically attractable material, said float includes at least one extension extended therefrom and made of magnetically attractable material for acting with said at least one block. 7. The flush tank as claimed in claim 4 further comprising a stop attached to said frame, for engaging with said float and for limiting a movement of said float relative to said frame. 8. The flush tank as claimed in claim 7, wherein said frame includes at least one post extended therefrom, said stop includes at least one leg extended therefrom and adjustably secured to said at least one post. 9. The flush tank as claimed in claim 8, wherein said stop includes a loop attached to said at least one leg and to slidably receive said at least one post. 10. The flush tank as claimed in claim 8, wherein said at least one post includes a plurality of apertures formed therein, said stop includes a catch provided on said at least one leg to selectively engage into either of said apertures of said at least one post, to adjustably secure said at least one leg of said stop to said at least one post. 11. The flush tank as claimed in claim 10, wherein said at least one leg includes a spring blade provided thereon to support said catch. 12. The flush tank as claimed in claim 11, wherein said at least one leg includes a hand grip provided on said spring blade to move said spring blade to disengage said catch from said at least one leg. 13. The flush tank as claimed in claim 1, wherein said electromagnetic device includes a core for acting with said float, and a coil disposed around said core, to move said core relative to said coil. 14. The flush tank as claimed in claim 13, wherein said electromagnetic device includes a housing to receive said core and said coil. 15. The flush tank as claimed in claim 13, wherein said electromagnetic device includes a duct to receive said core. 16. The flush tank as claimed in claim 13, wherein said electromagnetic device includes a container having a cavity formed therein to slidably receive said core. 17. A flush tank comprising: a receptacle for receiving water therein, an outlet pipe attached to said receptacle for discharging the water, a float disposed close to said outlet pipe to selectively block said outlet pipe, and to control an outward flowing of the water through said outlet pipe, and magnetically forcing means for magnetically forcing said float to block said outlet pipe, said magnetically forcing means including an electromagnetic device disposed in said receptacle for acting with said float, and said electromagnetic device including a core for acting with said float, and a coil disposed around said core, to move said core relative to said coil, and said electromagnetic device including a duct to receive said core, said duct including a cushioning member disposed therein to engage with and to cushion said core. 18. A flush tank comprising: a receptacle for receiving water therein, an outlet pipe attached to said receptacle for discharging the water, a float disposed close to said outlet pipe to selectively block said outlet pipe, and to control an outward flowing of the water through said outlet pipe, and magnetically forcing means for magnetically forcing said float to block said outlet pipe, said magnetically forcing means including an electromagnetic device disposed in said receptacle for acting with said float, and said float including a magnet engaged therein for acting with said electromagnetic device.
