(37) In addition, it is worth noting that circumferential outer side walls of the urine evaporation box 8, circumferential outer side walls of the heat recovery box, side walls of the transfer box 5-11, the top plate 5-17 of the transfer box 5-11, the top plate 5-6 of the pyrolysis furnace, side walls of the pyrolysis furnace 5-5, side walls of the first storage box 5-3, side walls of the second storage box 5-10, and the feeding door 5-4 are all made of heat insulation boards. The heat insulation boards can play a role of heat insulation to avoid waste caused by heat loss.

(38) In an optional solution of the embodiment, preferably, the heat insulation boards each include two stainless steel plates and a polyurethane foam plastic layer sandwiched between the two stainless steel plates.

(39) The specific working principle of the closestool with classification, collection and treatment functions in the embodiment is as follows.

(40) When the user is sitting on the closestool, the top plate 5-17 of the transfer box is opened through the control panel, the feces excreted by the user fall onto the collection container through the opening in the top plate 5-17 of the transfer box 5-11 (as shown in FIG. 2). When the user finishes defecation, the collection container 5-9 is lowered to the bottom of the pyrolysis furnace 5-5 (referring to FIG. 3) by pressing the feces treatment start button on the control panel 2, the top plate 5-17 of the transfer box 5-11 and the top plate 5-6 of the pyrolysis furnace are both closed, and then the feeding door 5-4 is opened. The solid heat media 5-2 stored in the solid heat media storage box are pushed into the pyrolysis furnace 5-5 under the combined action of gravity and the thrust of the push rod of the solid heat media storage box (referring to FIG. 4), and then the feeding door 5-4 is closed. The push rod of the solid heat media storage box is retracted to its original position, and the heating element 5-23 placed on a bottom surface of the pyrolysis furnace 5-5 starts heating. After heating for a period of time, the feces become carbonized feces after sufficient pyrolysis (referring to FIG. 5), and then the top plate of the pyrolysis furnace 5-5 is opened. The collection container 5-9 is lifted through the sliding rods 5-25. Under gravity, the solid heat media 5-2 fall into the pyrolysis furnace 5-5 from the meshes of the collection container 5-9. When the collection container 5-9 is moved out of the pyrolysis furnace 5-5, the top plate 5-6 of the pyrolysis furnace is closed, and the feeding door 5-4 is opened. Under the action of the second electric push rod 5-22, the solid heat media 5-2 in the pyrolysis furnace 5-5 are pushed into the solid heat media storage box by the second push plate 5-8, and then the feeding door 5-4 is closed. The push rod of the pyrolysis furnace 5-5 is retracted to its original position. When the collection container 5-9 is lifted to a designated position (the designated position refers to the position where the axis of the collection container 5-9 is coaxial with the second push plate 5-12, referring to FIG. 6), under the action of the first electric push rod 5-18, the carbonized feces are pushed into the second storage box 5-10 by the first push plate 5-12 (referring to FIG. 7), and then the push rod for collecting the carbonized feces is retracted to its original position (referring to FIG. 8). The lower removable insulation layer at the bottom of the feces collection and treatment device 5 is removed, so that waste heat in the feces collection and treatment device 5 can be recovered by means of the liquid heat media in the heat recovery device 6, and the feces treatment process is completed.

(41) After the user sitting on the closestool presses the fecal treatment start button to perform a feces treatment function, the anal cleaning start button can be pressed to flush anal opening of the user. The anal cleaning water falls on a surface of an upper cover plate of the feces collection and treatment device 5, flows into the anal cleaning water collection chamber 17 of the baffle plate 15 through the second liquid inlet hole 19 under gravity, and then is discharged into the municipal pipe network through the anal cleaning water discharge pipe 12 and sent to a municipal sewage treatment plant for treatment. Furthermore, through the second check valve 14 on the anal cleaning water discharge pipe 12, the anal cleaning water is discharged in one direction under gravity, and the odor in the pipe cannot flow back into the closestool.

(42) When the user sitting on the closestool excretes urine, the urine treatment start button is pressed, and the urine flushing device 10 sprays the anal cleaning water to wash the urine. Under gravity, the mixture of the urine and the flushing water flows into the urine collection chamber 16 through the first liquid inlet holes 18, and is discharged into the urine evaporation box 8 through the urine collection pipe 11 for evaporation treatment. In addition, the first check valve 13 on the urine collection pipe 11 can prevent the odor from overflowing in the process of urine collection and evaporation.

(43) The start and stop of the evaporation process in the urine evaporation box 8 are controlled by the sensor inside the dehumidifier 7. When humidity of the gas in the urine evaporation box 8 is higher than saturated vapor pressure, the dehumidifier 7 is started to evaporate the urine and the anal cleaning water entering the urine evaporation box 8. During the evaporation process, the heat recovery device 6 heats the urine evaporation box 8 through the heat conduction between the liquid heat media and the base plate at the bottom of the heat recovery device 6. When the humidity of the gas in the urine evaporation box 8 is lower than saturated vapor pressure, the dehumidifier 7 stops working.

(44) In this embodiment, by using the technical solutions of the structure of the device and the using method of the device, feces and urine can be effectively treated on site. Furthermore, carbonized feces and urine crystals which can realize resource utilization are produced. Compared with the traditional feces and urine treatment mode of flushing in closestool, collecting by sewage pipe network, and centralized treatment in sewage treatment plants, the treatment cost is reduced, the carbon sequestration of organic waste is realized, the carbon emission is reduced, the phosphorus resources in sewage are recovered, and the water resources are saved by reducing flushing water. The economic benefits, ecological benefits and social benefits are obvious.
