M246370 V. Creation Instructions U) I. [Creation belongs to this creation is to use the time to control the bonnet of the water outlet and the flat water-saving toilet. 2. [Prior art Taiwan is a problem of lack of water without rainfall. However, for example, a litre of water is saved in a toilet seat of water resources. In addition, the SARS epidemic source should be switched on and off to prevent the possibility of SARS. Technical Field] A kind of infrared-driven time driven by a sharp wheel can greatly reduce the consumption of water. It can be used to infect diseases from outside lines ~ an infrared water-saving toilet structure, especially the three-stage water supply and the use of stepping motors. In countries where tooth movement and the use of inductive switches to set the flushing volume are not easy to store water, often due to a short period plus summer is coming, it is very likely to face. If the toilet is daily, J rf- ^ -T- * The amount of water in the name of the ten masters will be a considerable amount. It will cause panic among the people, how to reduce the sense of a very heavy | *, so use red A new type of infrared water-saving toilet patent "Smart flushing toilet", which is used to increase the sense of touching the virus by touching the hands. For example, the Republic of China No. 8722 2 1 4 'bucket, which includes: a water tank; Smart flush shoulder for storing water for flushing of this toilet · Above the bucket, including water inlet and outlet

The water tank inlet is used to control the water tank, 隹: the water tank inlet control device, the water outlet and the toilet are used to control the water 1, a solenoid valve is installed in the water tank device; an electronic control system is used to: 2: water action ; -The switch action of the water inlet finger, the electronic control system first packs eight '" k number to control the electrical and infrared receiver, infrared emission cry Z; complex array infrared service X 耵 is used to emit infrared radiation to For a while
