       [0001]    The present invention relates to the field of personal and household sanitation device, and more particularly to a wheelchair-type excrement automatic cleaning apparatus without need of undressing and dressing which is designed for the mobility disabled person. 
         [0002]    Currently put into the market is an excrement and urine automatic disposal system, which is designed for the mobility disabled person and serves to automatically dispose the excrement and urine of the mobility disabled person. The excrement and urine automatic disposal system generally comprises an excrement and urine automatic disposal apparatus and a toilet cooperating with the excrement and urine automatic disposal apparatus. The excrement and urine automatic disposal apparatus is generally provided with an evacuation barrel, a negative pressure device, a hot water device, a hot air device and a control device. The evacuation barrel accommodates excrement and urine discharged from the human body, and is connected with an excrement and urine container via a valve. The excrement and urine container is used to pack and dispose excrement and urine discharged from the evacuation barrel. The toilet is generally provided with an excrement collecting area, a hot water output pipe and a hot air output pipe. The excrement collecting area is further provided with an excrement and urine discharging port which is connected with an excrement and urine excretion duct. The excrement and urine excretion duct is connected with the evacuation barrel via the negative pressure device, for drawing the excrement and urine into the evacuation barrel by negative pressure. The hot water output pipe is connected with the hot water device via a hot water pipe, for flushing the excrement and urine place of a user. The hot air output pipe is connected with the hot air device via a hot air pipe, for drying the excrement and urine place of the user. The control device comprises an interactive interface, which is provided with an ON/OFF switch. In particular, the control device may further be provided with a remote controller for switching ON/OFF. 
         [0003]    However, the existing toilets for cooperating with the excrement and urine automatic disposal apparatus have a common feature in that, when the mobility disabled person needs defecation, it is necessary for the user to have a self-care ability or a caregiver to install various toilets as mentioned above to the excrement and urine discharging place; and when the defecation is complete, it is also necessary for the caregiver to remove the toilets. It is impossible to automatically and intelligently discharge the excrement and urine without help from others. Especially due to the operation mode, material and structure of the existing toilet, it can not keep contact with the human body for a long time, and can only be removed from the excrement and urine discharging place by means of a mechanical transmission means or manually by the caregiver. It is relatively inconvenient for use. Besides, when the mobility disabled person goes out, it is impossible to use the toilet at any time and anywhere, which greatly limits the user from going out.

         [0017]    Firstly, when the user wears the self-adapting pants and trousers and is seated in the wheelchair, he can manipulate the wheelchair by himself or the wheelchair can be manipulated by others to freely move about, which largely expands the range of movement. During defecation, the excretion duct of self-adapting pants passes through the opening at the crotch of trousers to communicate with the excrement collecting device. In this way, the user may be seated in the wheelchair and start the control device, so as to complete the process of defecation and automatic cleaning up. It is not necessary to undress the self-adapting pants and trousers, so that it is not only possible to eliminate the tedious adjustment before and after use, but also to free the caregiver from the tedious cleaning up process on the human body discharging place. After excrement and urine discharged by the human body is flushed to the excrement collecting device, it is only necessary for the caregiver to dispose the excrement, urine and waste water in the excrement collecting device, which can largely improve working conditions of the caregiver and facilitate carrying out the nursing services. By using self-adapting pants made of a soft facing material as the toilet, and designing appropriately the self-adapting pants, such a toilet in the form of pants not only has various functions of the existing toilet, but also is soft and comfortable, so that it can be worn on a user for a long time, and substantially make no difference from the ordinary pants in respect of comfort, wearing process and changing time. During excrement and urine, the user does not need help from others to dress and undress the toilet, and can start the human body excrement disposal apparatus at any time by himself to defecate, so that it is very convenient for use. The moisture generated in the self-adapting pants during hot air drying is drawn into the excrement collecting device by the negative pressure device, which decreases the time for drying. In addition, the moisture is substantially not removed through the human body, and this provides the passage for discharging the moisture, thus saving energy and increasing the comfort for the human body. 
         [0018]    Secondly, the self-adapting pants are provided with a buttock bump at the rear inner surface of the excrement collecting area, so that when the user wears the self-adapting pants and sits down, the buttock bump is clamped in the buttock cleavage, thus pushing the left and right buttocks to both sides and preparing for defecation. The excrement collecting area is provided with a convex tube at the front outer surface, and the excrement port is provided with a quick connector, wherein the convex tube and the quick connector can be connected with respective pipe of the fully automatic disposal apparatus via a pipe, so that it is possible to complete the automatical disposal process of defecating and cleaning up, and there is no need for tedious adjustments from medical workers or caregivers before and after use, thus making it very convenient for use. In addition, the self-adapting pants have a simple and reasonable structure, and the convex tube is provided at the outer surface of the self-adapting pants, so that it will not bring discomfort to the human body, and it is also possible to form self-adapting pants as thin as the common pants, thus making it comfortable and fit to wear. 
         [0019]    Thirdly, the self-adapting pants are made as movable pants which can be opened or closed on both sides, and thus are more convenient for dressing and undressing. The excrement port of the self-adapting pants is provided with a quick connector at the outer surface, and it has a simple and reasonable structure, so that the user can wear the self-adapting pants for a long time. The quick connector is inserted into the inlet end of the excretion duct by passing through the opening at the crotch of the trousers, so that during cleaning up the defecation it is possible to not only form a sealing connection, but also avoid the tedious adjustments like dressing and undressing, which decreases the user&#39;s sense of inconvenience and is very convenient for use.

         [0037]    The excrement collecting device  21  comprises an excrement container  210  and an excretion duct  213 , and the excrement container  210  comprises a cover plate  211  and a case body  212 . The case body  212  has a hollow chamber. The hollow chamber is divided into an excrement collecting chamber  215  and a negative pressure chamber  216  by a partition plate  214 . The partition plate  214  is provided with a vent hole  217  for communicating with the excrement collecting chamber  215  and the negative pressure chamber  216 . The cover plate  211  cooperates with the case body  212  in a sealing manner. The corresponding excrement collecting chamber  215  over the cover plate  211  is provided with an excrement port  218 . The excrement port  218  forms a movable connection with the quick connector at the outlet end of the excretion duct  213  via a quick connector. The inlet end of the excretion duct  213  is provided with a quick connector  341 ′. The quick connector  341 ′ forms a movable connection with the quick connector  341  at the excrement port  34  of the self-adapting pants  3 , so that it is convenient to detach the excrement container  210  for cleaning up. At the upper portion of the left chamber wall, the negative pressure chamber  216  is provided with an opening which is provided with a quick connector  219 . The quick connector  219  has a port which is located inside the negative pressure chamber  216  and bends downward, so that the port of the quick connector  219  outside the negative pressure chamber  216  is over the port inside the negative pressure chamber  216 , and the two ports are arranged in a staggered manner. The quick connector  219  is connected with the quick connector provided at the port of the negative pressure device  22 . Of course, the quick connector  219  may also be provided at the chamber wall at the front and rear sides of the negative pressure chamber  216 , and the specific installing position can be determined by the port of the negative pressure device  22 . The excrement container  210  is connected with the wheelchair  1  in a snapping or sliding manner to form a removable connection. The excrement container  210  is connected with the self-adapting pants  3  via the excretion duct  213 , to receive excrement and urine discharged by the human body. Of course, the excrement container  210  further receives the waste water after flushing the user&#39;s excrement and urine by the hot water device  24 . After the user completes defecation, the excrement container  210  may be removed from the wheelchair  1  for cleaning up. The inner walls of the cover plate  211  and the case body  212  are coated with a layer of anti-adhesive material in order to facilitate cleaning up. 
         [0038]    The negative pressure device  22  comprises a vacuum pump. The vacuum pump is connected with the excrement collecting device  21  via a pipe, and serves to form a negative pressure, so as to draw excrement and urine discharged by the human body into the excrement collecting device  21 . The pipe for communicating with the excrement collecting device  21  with the self-adapting pants  3  and the pipe for communicating with the excrement collecting device  21  and the negative pressure device  22  are arranged in a staggered manner, in order to prevent excrement and urine in the self-adapting pants  3  from being directly drawn into the negative pressure device  22 . In this embodiment, the self-adapting pants  3  communicate with the excrement collecting chamber  215  of the excrement container  210  via the excrement port  34 , the excretion duct  213 , and the excrement port  218  of the cover plate  211 , while the negative pressure device  22  communicates with the negative pressure chamber  216  via its pipe and the opening in a side of the excrement container  210 . 
         [0039]    As a specific embodiment of the negative pressure device  22 , the negative pressure device  22  comprises a vacuum pump  221  and a discharging filter, the vacuum pump  221  is connected with the excrement collecting device  21  via a pipe, and the discharging filter is arranged between the vacuum pump  221  and the excrement collecting device  21 . By means of the negative pressure action in the vacuum pump  221 , the waste in the self-adapting pants  3  is drawn into the excrement collecting device  21 . 
         [0040]    The positive pressure device  23  is connected with the self-adapting pants  3  via a pipe, and is used to form a positive pressure to expand the excrement collecting area  33  of the self-adapting pants  3 , so that the negative pressure device  22  can draw the waste into the excrement collecting device  21  more smoothly. In particular, as a preferred embodiment of the positive pressure device  23 , the positive pressure device  23  comprises an air pump, an air filter, a pressure sensor, an electronically controlled pressure relief valve and a check valve. The air pump communicates with the atmosphere via the air filter, so as to ensure cleanliness of the air. The check valve is arranged in the pipe between the air pump and the self-adapting pants  3  to maintain the air pressure in the self-adapting pants  3 . Both the electronically controlled pressure relief valve and the pressure sensor are arranged in the self-adapting pants  3 . The electronically controlled pressure relief valve is connected with and controlled by the control device  26 . Once the use of the wheelchair-type excrement automatic cleaning apparatus without need of undressing and dressing is complete, the electronically controlled pressure relief valve releases the air pressure in the self-adapting pants  3 , and the pressure sensor functions as an overpressure protection. 
         [0041]    The hot water device  24  communicates with a hot water output pipe of the self-adapting pants  3  via a pipe, and provides water flow for flushing the user&#39;s excrement and urine place. After the water flow from the hot water device  24  flushes the user&#39;s excrement and urine place, it directly flows into the excrement collecting chamber  215  of the excrement collecting device  21  via the excretion duct  213 . That is, the connection part between the hot water device  24  and the self-adapting pants  3  should be at a higher position. In this embodiment, the hot water device  24  is provided at a higher portion of the chair back  12  of the wheelchair  1 , and it specific position is adjusted according to actual requirements, which is not described herein in detail. 
         [0042]    In order to keep the excrement collecting device  21  clean, the hot water device  24  further comprises a flushing reversal valve which is provided at the pipe between the water pump and the self-adapting pants  3 . The flushing reversal valve is further connected with the excrement collecting device  21  via a pipe. In this way, by means of the flushing reversal valve, it is possible to flush the excrement collecting device  21 , so as to improve its cleanliness and avoid bacteria growth. 
         [0043]    As a specific embodiment of the hot water device  24 , the hot water device  24  comprises a water tank, a water pump, a heating device and a temperature sensor. The water pump, the heating device and the temperature sensor are all provided in the water tank. The heating device heats the water in the water tank, and keeps at a constant temperature with the aid of the temperature sensor. The water pump further communicates with the hot water output pipe of the self-adapting pants  3  via a pipe. Preferably, there are two water tanks, namely, a large water tank and a small water tank. The large water tank is used to store water added with a disinfectant. The heating device, the temperature sensor and the water pump are all arranged in the small water tank, so that the heating device only needs to thermally insulate the small water tank as desired, so that the power consumption is decreased. Of course, a liquid level sensor may further be provided in the large water tank for monitoring the water level in the large water tank. When the water level is below a lower limit, the liquid level sensor issues an alarm. 
         [0044]    The hot air device  25  is connected with the self-adapting pants  3  via a pipe, and produces an air flow for drying the user&#39;s excrement and urine place. In particular, after drying the user&#39;s excrement and urine place, the air flow produced by the hot air device  25  is discharged via the negative pressure device  22 . 
         [0045]    As a specific embodiment of the hot air device  25 , the hot air device  25  comprises a heat exchanger and an air pump. The air pump is connected with a hot air output pipe of the self-adapting pants  3  via a pipe. The heat exchanger is arranged in the pipe between the air pump and the self-adapting pants  3 . 
         [0046]    The control device  26  is connected with the negative pressure device  22 , the positive pressure device  23 , the hot water device  24  and the hot air device  25 , and controls the cooperation among them, i.e., controls the operating order of these devices. Of course, the control device  26  may be further provided with a remote control unit as necessary, in order to switch on and off the whole wheelchair-type excrement automatic cleaning apparatus without need of undressing and dressing in a wireless manner. In order to avoid interference from the neighboring apparatus, a dual coding is applied in the remote control signal. Of course, in order to enable the control device  26  to read from each device, an A/D or D/A converting unit is further built in the control device  26  for analog to digital conversion and digital to analog conversion. An interactive unit  261  may be further provided at the armrest of the wheelchair  1  as required, as shown in  FIG. 2 , which may enable to set and modify the apparatus control parameters, set the operation mode, display the current operation status, and provide manual control buttons or the like. In particular, the interactive unit  261  uses a LCD display with a touch screen, so that the user can manipulate manually. It is noted that the pipe in the present invention can be formed by silicone, latex or the like, and a quick connector may be further arranged between the pipe and the self-adapting pants  3  to improve convenience during assembly and disassembly. 
         [0047]    In this way, the wheelchair-type excrement automatic cleaning apparatus without need of undressing and dressing of the present invention performs the following procedures in a sequential and cycling manner under control of the control device  26 . Firstly, the positive pressure device  23  expands the excrement collecting area  33  of the self-adapting pants  3  so that the user can defecate. The negative pressure device  22  draws excrement and urine discharged by the user into the excrement collecting chamber  215  of the excrement collecting device  21 , then the user&#39;s excrement and urine place is flushed with the water flow blown from the hot water device  24 , the user&#39;s excrement and urine place is dried by the air flow produced by the hot air device  25 , and then the excrement container  210  of the excrement collecting device  21  is removed. The caregiver only needs to clean up the excrement container  210 . As a result, the present invention can largely improve working conditions in which the caregiver cleans up the excrement collecting device  21 , and facilitate carrying out the nursing services. In addition, the moisture generated in the self-adapting pants  3  during hot air drying is drawn into the excrement collecting device  21  by the negative pressure device  22 , which decreases the time for drying. In addition, the moisture is substantially not removed through the human body, and this provides the passage for discharging the moisture, thus saving energy and increasing the comfort for the human body. 
         [0048]    The main part of the self-adapting pants  3  is a pant body  30 , as shown in  FIG. 6 . The facing material of the pant body may be made of an ordinary facing material, like cotton, Terylene, nylon, spandex, Lycra, silk, Modal or the like. In this embodiment, the pant body  30  is movable pants which have a structure similar with diaper. A front piece  31  and a rear piece  32  are provided with respective sticking parts  38 ,  38 ′ on both sides. The front piece  31  and the rear piece  32  may be stuck to form a triangular or straight angle pant body  30 . In a preferred embodiment, the pant body  30  is made of a cotton facing material, which may be treated naturally and is waterproof and air permeable. 
         [0049]    The excrement collecting area  33  is provided at the crotch of the pant body  30  near the excrement and urine discharging port, as shown in  FIG. 6 . The four corners of the excrement collecting area  33  are rounded angles or elliptical to better fit the body. In another embodiment of the excrement collecting area  33 , as shown in  FIGS. 7-8 , the excrement collecting area  33  is elliptical corresponding to the buttocks and has an area tapering from the rear to the front, and an inner surface of the excrement collecting area  33  is a smooth curved surface fit to the human body. The excrement collecting area  33  is provided with a buttock bump  331  made of soft rubber at the rear inner surface. The buttock bump  331  is a triangular bump with smooth edges. When the user wears the self-adapting pants  3  and sits down, the buttock bump  331  is clamped in the buttock cleavage, thus pushing the left and right buttocks to both sides and preparing for defecation. The excrement collecting area  33  is provided with a concave groove  332  at the front. A convex tube  333  is provided at the groove  332  and on the outer surface of the pant body  30 . The convex tube  333  is provided with four through-holes, each of which is connected with the respective pipe for the positive pressure device, the disinfection cleaning fluid, the hot water device and the hot air device of the excrement and urine fully automatic disposal apparatus. In this way, the water flow blown from the convex tube  333  may quickly aggregate along the groove  332  after flushing to enter the excrement port  34 , instead of spreading around. The convex tube  333  has an inlet end  334  at an outer surface of the pant body  30  and an outlet end  335  at an inner surface of the pant body  30 .

The excrement port  34  is provided with a quick connector  341  compatible with the inlet end of the excretion duct  213 . The quick connector  341  passes through the excrement port  111  of the cushion  11 , and is inserted into the inlet end of the excretion duct  213 . Of course, it is possible to arrange the inlet end of the excretion duct  213  and the excrement port  111  of the cushion  11  in a movable connection. The quick connector  341  is made of a soft material like silicone, latex or the like, so that it is very soft, comfortable and less sensible when being contact with the human body. When the user leaves the wheelchair  1  to sit down or lie down, the quick connector substantially has no effect on the human body. The quick connector  341  may be formed in a shape of cone, truncated cone, circle, ellipse, polygon or the like. 
         [0051]    The excretion duct  213  is a thick hose made of a soft material like silicone, latex or the like. The thick hose may be connected with the self-adapting pants for a long time, and is soft, comfortable and less sensible when being contact with the human body. The thick hose substantially has no effect on the human body. The inlet end of the excretion duct  213  is provided with another quick connector  341 ′ corresponding to the quick connector  341 . The quick connector  341  may be quickly fastened with the quick connector  341 ′, so that the excrement collecting area  33  communicates with the excrement collecting chamber  215  of the excrement container  210  via the excrement port  34  and the excretion duct  213  in sequence. 
         [0052]    There are two embodiments for the self-adapting pants  3 . The first embodiment is shown in  FIG. 9 . The pant body  30  is further provided with an inflating pipe  35 , a hot water output pipe and a hot air output pipe. The hot water output pipe comprises a urine spray pipe  36  and an excrement spray pipe  36 ′. The hot air output pipe comprises a urine hot air pipe  37  and an excrement hot air pipe  37 ′. The inflating pipe  35 , the urine spray pipe  36 , the excrement spray pipe  36 ′, the urine hot air pipe  37  and the excrement hot air pipe  37 ′ are thin hoses made of a soft material like silicone, latex or the like. 
         [0053]    The outlet end of the inflating pipe  35  is located in the pant body  30 . The inlet end of the inflating pipe  35  is formed by extending the nozzle of the pant body  30  to the outside of the pant body  30 , and can be connected with the air outlet of the positive pressure device  23  via a pipe. 
         [0054]    The outlet ends of the urine spray pipe  36 , the excrement spray pipe  36 ′, the urine hot air pipe  37  and the excrement hot air pipe  37 ′ extend to respective positions in the pant body  30 , i.e., corresponding to the position of the excrement port or that of the urine excrement port. The inlet ends of the urine spray pipe  36 , the excrement spray pipe  36 ′, the urine hot air pipe  37  and the excrement hot air pipe  37 ′ are formed by extending from the nozzle of the pant body  30  to the outside of the pant body  30 , and can be connected with respective pipe of the hot water device  24  and the hot air device  25  of the fully automatic disposal apparatus  2 . 
         [0055]    The inflating pipe  35 , the urine spray pipe  36  and the urine hot air pipe  37  are fixedly arranged in the front piece  31  of the pant body  30 . The excrement spray pipe  36 ′ and the excrement hot air pipe  37 ′ are fixedly arranged in the rear piece  32  of the pant body  30 . It is also possible to arrange interlayers in the front piece  31  and the rear piece  32  of the pant body  30 , and then arrange the inflating pipe  35 , the urine spray pipe  36 , the excrement spray pipe  36 ′, the urine hot air pipe  37  and the excrement hot air pipe  37 ′ in respective interlayers. 
         [0056]    During use, the user may start operation of the wheelchair-type excrement automatic cleaning apparatus without need of undressing and dressing manually or via a wireless remote controller. In addition, it is also possible to set a sensor automatic mode to start the wheelchair-type excrement automatic cleaning apparatus without need of undressing and dressing upon automatically detecting a defecation action. The quick connector  341  of the self-adapting pants  3  passes through the opening at crotch of the trousers and is arranged within the excretion duct  213 . The control device  26  opens the above mentioned cover of the excrement port  111  of the cushion  11 . The positive pressure device  23  produces an air pressure and inflates the pant body  30  via the inflating pipe  35 , so that the excrement collecting area  33  is expanded and falls to form a discharging space for excrement and urine. At this time, the wheelchair-type excrement automatic cleaning apparatus without need of undressing and dressing produces a negative pressure at the excrement port  34  via the negative pressure device  22  and the excretion duct  213 . When the user begins to discharge excrement or urine, the discharged excrement or urine is immediately drawn by the negative pressure to the excretion duct  213 , and finally falls into the excrement container  210 . With the control device  26 , the blown hot water is controlled at a predetermined temperature. The hot water is blown to flush the excrement and urine place of the human body via the urine spray pipe  36  and the excrement spray pipe  36 ′. After flushing, the blown hot air is controlled at a predetermined temperature with the control device  26 . The hot air is blown to the excrement place and the urine place via the urine hot air pipe  37  and the excrement hot air pipe  37 ′, so as to dry the excrement place, the urine place, and the whole excrement collecting area  33 . The hot air containing moisture is finally drawn by the negative pressure through the excretion duct  213 , so as to form a moisture circulation system, which quickly dries the human body and the self-adapting pants. 
         [0057]    The second embodiment of the self-adapting pants  3  is shown in  FIG. 10 , which differs from the first embodiment in the structure of the pant body. The pant body  30  may be a triangular pant with a conventional structure, and may also be a four-angle pant. Besides, pneumatic sealing rings  39 ,  39 ′ and  39 ″ are sewed at the waistline and nozzle of the pant body  30  as sealing parts. The pneumatic sealing rings  39 ,  39 ′ and  39 ″ have a ring structure sewed by an airtight facing material, and have a certain flexibility to fit to fat or thin human bodies. The pneumatic sealing rings  39 ,  15  and  16  are provided with inflating ports  391 ,  391 ′ and  391 ″, respectively. The inflating ports  391 ,  391 ′ and  391 ″ are connected with the inflating device via a pipe, respectively. During use, the wheelchair-type excrement automatic cleaning apparatus without need of undressing and dressing produces a positive pressure gas via the inflating device. The positive pressure gas inflates the pneumatic sealing rings  39 ,  39 ′ and  39 ″ via the inflating ports  391 ,  391 ′ and  391 ″. The pneumatic sealing rings  39 ,  39 ′ and  39 ″ are quickly inflated to expand, thus tightening the waistline and nozzle of the pant body  30  to form a sealing. As a result, when the pant body  30  is inflated by the inflating pipe  35 , and the soft and waterproof excrement collecting area  33  is expanded to form a discharging space, it is possible to improve the tightness of the pant body  30 , and thus to quickly form a discharging space. In the above-mentioned inflating device, the positive pressure device  23  or the hot air device  25 , the positive pressure device  23  or the hot air device  25  may communicate via a pipe with the pneumatic sealing rings  39 ,  39 ′ and  39 ″ respectively. 
         [0058]    The structure of other portions and the operation principle of this embodiment are identical to those of the first embodiment. 
         [0059]    In the present invention, the pants with a conventional structure that people have to wear in daily life are designed with a special structure to form self-adapting pants for the mobility disabled person.
