BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a movable sanitary care auxiliary device system, particularly to a movable toilet chair, which can pump clean water from a built-in reservoir container to a water supply tank and enable user to modulate and control the temperature of the water supply tank and seat temperature. After the user evacuates, the cleaning nozzle unit is manipulated to extend, retract and clean by a control unit. The user&#39;s waste and waste water are stored by a waste storing unit provided with monitoring and warning of the level of the waste liquid to achieve the requirements of easy manipulation, hygiene and health for a movable toilet chair. 
     2. Description of the Prior Art 
     The conventional movable toilet chair is provided with a toilet cover horizontally on an exposed metal frame for hip sitting and pivoted with a liftable toilet lid on the toilet cover and installed with a collecting bucket below the toilet seat. 
     Due to the members applied in the conventional toilet chair are directly connected with the collecting bucket below the toilet cover, the user&#39;s waste are easy stained on user&#39;s hip for dropping on the collecting bucket directly. Additionally, the waste are not monitored and processed and the foul odor of the waste further affects environmental air quality. Furthermore, after the user evacuates the user cannot sit down, stand up or wipe and clean by self for handicapped reason. The user will have to rely on others&#39; support to wipe and clean. It will cause the inconvenience of others and derogate the user&#39;s self esteem. 
     Due to the toilet seat of the conventional toilet chair is not designed ergonomically but solves the problem of temporarily collecting the user&#39;s waste. The conventional toilet chair is displayed in dull and frigid. Not only it is unstable in support but also the direct contact of the cold toilet seat will cause the user to feel tremble and uncomfortable. 
     However, the conventional toilet chair is not provided with any additional function. The user not only cannot stand up by self but also the helper has to hold the user laboriously and wipe the anal part of the user while the user is in the state of standing after the user evacuates. It often causes the user to feel uncomfortable and psychological burden due to the helper does not clean thoroughly and is the user may be infected by germs accordingly. 
     Furthermore, the abovementioned conventional toilet chair is designed by the temporary need of evacuation, its function at most works to receive the waste of the user. Therefore, it can not compare with the toilet in the restroom in use. If the waste is not cleaned immediately after evacuating there will be a problem of foul odor spread and affects air quality inside the space. 
     In viewing of the abovementioned problems, the inventor of the present invention endeavors to improve and successfully invents the movable sanitary care auxiliary device system of the present invention after years of research. 
     SUMMARY OF THE INVENTION

At this moment the pivotal locations of the seat cushion  71  and the outer lid  72  are exactly at both sides of the control unit  45  of the first shell body  4 . 
     Furthermore, referring to  FIG. 8 ,  FIG. 9  they are schematic views of the movable auxiliary sanitary care apparatus of the present invention, which is not in use and in use respectively. When the movable auxiliary sanitary care apparatus of the present invention is in use the outer lid  72  of the riding unit  7  is first lifted for user to sit on the seat cushion  71  to evacuate. After the user evacuates the user can operate the control panel  61  of the third shell body  6  to drive the cleaning nozzle unit  46  to extend correspondingly to clean the anal part of the user. At this moment the cleaning nozzle unit  46  cleans and undergoes germicidal treatment of the anal part of the user directly by means of the warm water of the water supply tank  33  and the built-in germicidal light source to achieve the substantial benefits of cleaning and antisepticising without wiping. 
     Referring the following processes, they are the operation steps of the present invention that the control unit  45  supplies warm water of the water supply tank  33  when warm water is delivered to the cleaning nozzle unit  46  for the user to clean. 
     (a) The user pushes the control panel  61  to turn on the control unit  45  and send a signal to drive the water supply device. After the warm water of the water supply tank is delivered to the cleaning nozzle unit  46  it goes on performing step (b); 
     (b) The control unit  45  transmits a signal to the liquid level detection device  32  to determine if the clean water of the reservoir container  31  is higher than the predetermined lower limit value. If the clean water is higher than the lower limit value, it goes on performing step (c). If the determination result is not higher than the lower limit value, it performs step (e); 
     (c) The control unit  45  transmits a signal to drive the pumping device to drive the pumping device to pump the clean water of the reservoir container  31  to the water supply tank  33 . At the same time the control unit  45  drives the heating device to heat the clean water of the water supply tank  33  to a predetermined temperature to go on performing step (d); 
     (d) The control unit  45  transmits a signal to the liquid level detection device  32  to detect if the clean water of the reservoir container  32  is lower than a predetermined lower limit value. If the clean water has not reached the lower limit value, it goes on performing step (b). If the determination result has reached the lower than the lower limit value, it goes on performing step (e); 
     (e) If the clean water of the reservoir container  31  has reached the lower limit value, the control unit  45  transmits a warn signal and sound to the control panel  61 . At the same time the power supply for the pumping device, water supply device and heating device are turned off and then goes on performing the determination program of step (f); 
     (f) The control unit  45  monitors the liquid level detection device  32  to determine if the clean water of the reservoir container  31  is higher than a predetermined lower limit value. If the clean water is higher than the lower limit value, it goes on performing step (a). If the determination result is not higher than the lower limit value, it goes on performing step (e). 
     Accordingly, by means of the movable sanitary auxiliary care apparatus of the present invention it takes advantage of the support unit  1  that its frame not only has the chair leg section  13  to position stably and moves conveniently and the protection of the exterior shape of the shell unit but also the control panel  61  of the third shell body  6  installed on the shell unit to drive the central processing unit which connects and controls all power sources such as the lifting unit  2 , the pumping device of the reservoir container  31 , the water supply device and heating device of the water supply tank  33 , the germicidal light source of the cleaning nozzle unit  46 , ejecting water and extending/retracting movement and the convenient electronic control of the toilet chair for lifting. Furthermore, when the riding unit  7  of the present invention is not in use, the design of the outer lid  72  covered by foam rubber and soft fabric can be used as a chair for user to achieve the substantial benefits of barrier free and multi-function so as to enhance the value of the industry application and market competition. 
     Many changes and modifications in the above-described embodiment of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
