Title: Activation system for electronic urinal

Description:
FIELD OF THE INVENTION 
     The present invention relates to a urinal, and more particularly to an activation system for electronic urinal capable for saving water and power. 
     BACKGROUND OF THE INVENTION 
     Water resources are more and more important for developing environments and nations. The rainfall is not regular due to weather changes. Every country is focusing on how to effectively saving water. The conventional urinal is mainly controlled by the push switch. Although it needs no power to control, its drawback is that the hand of the user must press and touch the push switch to result in polluting the push switch or making germs remain on it. Therefore, it makes some user be not willing to press the push switch so as to make the toilet dirty. In order to improve the drawback of the conventional urinal, the sensing urinals are provided to the public facilities. The sensing urinals are applied by the infrared inflection principle to sense the human body. When the user is closing the front side of the urinal, an emitting tube of the sensor emits the infrared to the user&#39;s body and then reflects from the user&#39;s body to a receiving tube. The reflection signal is processed to control the solenoid valve to provide water to wash the urinal. When the user left from the sensor of the urinal, there is no infrared reflection and the solenoid valve still provides water to wash the urinal and shuts down. It may effectively save water resources and prevent the user from touching the germs remained on the urinal. 
     However, the above mentioned sensor and solenoid valve of the sensing urinal must operate all day long so that the batteries of the sensing urinal must be replaced frequently. It may increase the cost and make the operation inconvenient. The replaced batteries are not environment friendly.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to the drawings where like characteristics and features among the various figures are denoted by like reference characters. 
     Please refer to  FIGS. 1 to 3 , the activation system for electronic urinal may comprise a urinal  1  and a control unit  2 . 
     The urinal  1  may be fluidly communicated with an inlet pipe. 
     The control unit  2  may be arranged between the urinal  1  and the inlet pipe for controlling the inlet pipe to be shut down or opened. The control unit includes a solenoid valve  21 , a sensor  22 , and a power supply  23 . The solenoid valve  21  is used for controlling to water or seal. The sensor  22  is electrically connected to the solenoid valve  21  and used for sensing human body. The power supply  23  provides power to the solenoid valve  21  and the sensor  22 . 
     The control unit  2  has an activation switch  24  which is electrically connected to the solenoid valve  21 . The activation switch  24  has a wireless transmission module  241  and a timing controller  242  for turning off the wireless transmission module  241 . The activation switch  24  is pressed so that the wireless transmission module  241  is activated to set water discharge and a turn-off time of the solenoid valve  21  and is turned off after a preset time counted by the time controller  242  to save power. 
     The effects of the activation system for electronic urinal of the present invention may be achieved and described as follows. 
     Firstly, please refer to  FIGS. 1 to 3 , when a user wants to set the functions of the urinal  1 , the user may press the activation switch  24  to activate the wireless transmission module  241  to transmit, receive, or process a setting command from a mobile device, such as setting the water discharge and the turn-off time of the solenoid valve  21 . The power may be saved because the wireless transmission module  241  is turned off after a preset time counted by the time controller  242 . 
     Secondly, please refer to  FIGS. 1 to 3 , the wireless transmission module  241  is electrically connected to the solenoid valve  21  so that the user may set an open diameter of the solenoid valve  21  to control water discharge by a mobile device. 
     Thirdly, please refer to  FIGS. 1 to 3 , the wireless transmission module  241  is electrically connected to the sensor  22 . The transmission module  241  has a storage unit  243  which may record user&#39;s customs, such as wash time and quantity of water for each wash. The above mentioned information may be transmitted to the mobile device  30  to provide the user to interpret and further to adjust the relative parameters of the elements.
