Other structures of the wheelchair 1 are the same as those of the existing wheelchair on the market, and will not be described here again.
As shown in fig. 6, the stool detection unit 21-7 includes a signal transmission module and a signal reception module, which are disposed at both sides of the inflow port 21-6, and in this embodiment, the stool is detected by using an infrared transmitter and an infrared receiver, the infrared transmitter transmits infrared rays to the infrared receiver, and when excrement falls from the toilet bowl hole 11-1 and enters the stool accommodation chamber 22 through the inflow port 21-6, the infrared rays are blocked, and the signal transmitted to the control unit 21-1 by the infrared receiver changes, thereby indicating that the stool is detected. In other embodiments, the image sensor may be used to collect an image in real time, identify the image to determine whether the user urinates, and set a pressure sensor to increase the detection accuracy, so as to determine that the content of the urination and defecation accommodating bin 22 increases according to the pressure change.
As shown in fig. 10, the urine detecting unit includes an ammonia gas sensor 43 and a flow sensor 46, the ammonia gas sensor 43 is installed on the inner side wall of the urine cup 4, the second connection port 41 is provided at the bottom of the urine cup 4, and the flow sensor 46 is installed between the urine discharge port 45 and the second connection port 41.
The smell of urine mainly originates from ammonia gas generated by decomposition of urea in urine, and the generation of urine is preferably indicated by ammonia gas, so that the ammonia gas sensor 43 is used in this embodiment. In the design stage, the real urine can be used for multiple times to simulate the real situation, the ammonia concentration in the air is recorded by using the ammonia sensor 43 and is changed along with time, a plurality of curves are drawn, characteristic points in which the ammonia concentration is changed along with time are extracted, a characteristic curve is finally obtained, and meanwhile, the concentration of the point at which the ammonia concentration is suddenly changed at first is extracted as a threshold value. In the use phase, if the ammonia concentration detected by the ammonia sensor 43 exceeds a threshold value, the change of the ammonia concentration in the urine cup 4 with time is recorded in real time, the recorded concentration change curve is compared with the characteristic curve, and if the concentration change curve approximately coincides with the characteristic curve, the detection of urine is indicated.
Meanwhile, in order to avoid the situation that the urine output of a user is too small in a single time, the flow sensor 46 is designed, and as long as the liquid flows out of the urine cup 4 from the urine outlet 45 and enters the urine pipeline in the connecting hose 3, the liquid can be detected by the flow sensor 46.
In this embodiment, as shown in fig. 5, 7 and 8, a containing cavity and a mounting cavity are left in the containing box main body 21, the urine and feces containing bin 22 is a box body without a cover and is arranged in the containing cavity, the inflow port 21-6 is arranged at the top of the containing cavity, and the control unit 21-1, the urine pump 21-2, the warm water unit 21-3 and the warm air unit 21-4 are arranged in the mounting cavity; as shown in fig. 7, the warm water unit 21-3 includes a water pump 21-3-1, a heater 21-3-2 and a water tank 21-3-3, the warm air unit 21-4 includes a blower 21-4-1, a heating sheet 21-4-2 and a deodorizing device including activated carbon, an ultraviolet sterilizer, etc.; a battery 21-5 is also provided in the housing box body 21 for supplying power.
