Abstract:
A toilet sanitizing device is provided, wherein the toilet seat can be pre-heated before use and cleaned with liquid cleaner after use to avoid disease infection. The seat is raised by a servomotor into a position for cleaning responsive to signals from a pedal switch and an infrared detector.

Description:
BACKGROUND OF THE INVENTION 
     The toilet is a household necessity to everyone, and therefore, every family, hotel, and public place have toilets for people to use. Toilets located in the home normally are used only by family members, and will not pose any disease infection problem. Those in public places are exposed to the unknown potential infections by hundreds of users. 
     Toilet seat covers have not been accepted into individual family houses and have not proved cost effective in hotels and public facility use. Thus, there is a need for a cost effective toilet sanitizing device which minimizes the possibilities of getting infection. 
     SUMMARY OF THE INVENTION 
     It is the primary object of the present invention to provide a toilet sanitizing device which can clean the seat after each use. 
     It is another object of the present invention to provide a toilet sanitizing device which preheats the seat cover. 
     It is still another object of the present invention to provide a toilet sanitizing device which minimizes the possibilty of disease infection. 
     It is a further object of the present invention to provide a toilet sanitizing device which is easy to operate. 
     It is another further object of the present invention to provide a toilet sanitizing device which is inexpensive to produce.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to the drawings, and in particular to FIG. 1, the device comprises a cover 1, a toilet seat 2 and a pedal switch 3. The cover 1 is shaped like an ordinary toilet cover and has a bulge portion 11 having several hot air outlets 111 and water ejection holes 112. The bulge portion 11 is connected with a circuit box 12 and a cleaner box 13. 
     The toilet seat 2, as shown in FIG. 2, has two support fixtures 21, an axle 22 pivotally coupled to the support fixtures 21, and a gear 221 connected at one end of the axle 22. The pedal switch 3 has a pedal 31, a spring 32 having one end connected with the pedal 31 and the other end connected with a switch 33. A detector 4 disposed on cover 1 has a sensor 42 which uses infrared rays to determine if the seat 2 is occupied, and is covered in a case 41. A water pump 5 is installed in the bottom of the cleaner box 13 and has a blade 51 at its front end connected with both the water inlet pipe 52 and the outlet pipe 54 to pump water for cleaning the seat 2. The water inlet pipe 52 goes into a water barrel 53 which is located in the toilet tank and is lower than the water line of the tank for supplying water to be mixed with a cleaning solution. The water outlet pipe 54 has a universal joint at its front end that is connected to the cleaning liquid outlet pipe 55. The cleaning liquid is provided in bag 58 disposed above the cleaner box 13, having an outlet coupled to the outlet pipe 55, and has a cover 131 to contain it. The other end of the universal joint is connected to a loop pipe 56. Loop pipe 56 has a plurality of nozzles 57 facing the water ejection holes 112 of cover 1. 
     A blower 6 has a motor 61 to drive a blade 62 for blowing air out through an electric heater 63, which changes the air from cool to hot. The hot air flows through a loop pipe 64 to the outlet holes 641. The servomotor 7 has a gear 71 at one end which is engaged with the gear 221 at the end of axle 22, to drive the seat 2 up or down (shown in FIGS. 3 and 6). The seat 2 being raised to a position adjacent the cover 1 for the cleaning and heating operations, as shown in the flow diagram of FIG. 5. operations, as shown in the flow diagram of FIG. 5. 
     Referring additionally to FIG. 4, the auto-flusher 8 is a relay coupled to an output of microprocessor 91. The circuit box 9 includes microprocessor 91 and a timer 911. Each block shown controls one subassembly. The block 3 represents the pedal switch 3, the block 4 is the detector 4, the block 5 is the circuit for the water pump 5, the block 6 is the circuit for the blower 6, the block 7 is the circuit for the servomotor 7 and the block 8 is the circuit for the auto-flusher 8.
