[0037] In one embodiment of the present invention, the anti-slip pedal 37 is arranged in a lifting groove 38, and the lifting groove 38 is opened on both sides of the squat toilet 1. The anti-slip pedal 37 is slidably connected to the lifting groove 38. The bottom of the anti-slip pedal 37 is fixedly connected with a trigger block 36.

[0038] In one embodiment of the present invention, one end of the feces bin 8 is connected to a feces transmission pipe 42, and the bottom of one end of the feces bin 8 is connected to a urine transmission pipe 41. The feces transmission pipe 42 and the urine transmission pipe 41 are both connected to a feces and urine collecting device 44.

[0041] Working principle: When using the feces and urine ecological treatment device for rural dry toilets in cold areas of the present invention, before use, the user pre-adds charcoal powder, straw powder or other plant powders to the powder box 6 respectively, and then before going to the toilet, the relevant personnel can manually rotate the hand-cranked wheel 15, so that the hand-cranked wheel 15 drives the first synchronous pulley 16 to rotate, and the first synchronous pulley 16 then drives the second synchronous pulley 17 to rotate through the synchronous belt, and at this time, the first gear 18 coaxially fixedly connected thereto rotates with it and meshes and rolls with the second gear 19, so that the second gear 19 drives the third synchronous pulley 20 to rotate and drives the fourth synchronous pulley 21 through the synchronous belt, at this time, the fourth synchronous pulley 21 can drive the blowing impeller 12 in the powder diversion cover 10 to rotate through the driving shaft 13, so that the powder flowing into the material conduit 14 is blown into the feces bin 8 through the blowing port 11 under negative pressure and covers the surface of the filter cover 35, thereby effectively reducing the adhesion of feces when defecating, and then the user can go to the toilet;

[0042] When the user uses the toilet, he first steps his feet on the two anti-skid pedals 37. At this time, as the anti-skid pedals 37 are pressed up and down in the lifting grooves 38, the trigger block 36 arranged at the bottom of the anti-skid pedal 37 is pressed down and rolled in contact with the rollers 31 obliquely distributed on the docking slider 30 through the oblique cross section, so that the docking slider 30 pushes the slide bar 29 laterally, and then pushes one end of the swing rod 24 outward with the trigger support rod 25 as the active support point through the supporting cross bar 28, so that the other end of the swing rod 24 pushes the telescopic filter plate 27 into the filter cover 35 through the telescopic opening 26, so that the filter holes of the telescopic filter plate 27 and the filter cover 35 correspond one to one. At this time, the user can achieve feces and urine separation when using the toilet, and the urine reaches the bottom of the feces bin 8 through the filter holes. The urine is transferred into the urine transmission pipe 41 of the toilet and finally collected into the urine collection area in the urine and feces collection device. After using the toilet, when the user's foot leaves the anti-slip pedal 37, the cooperation of the reset spring 33, the limiting protrusion 32 and the support portion 45 causes the slide bar 29 to drive the docking slide block 30 to reset, thereby lifting and resetting the anti-slip pedal 37. At the same time, the rocker bar 24 pulls the telescopic filter plate 27 outward, so that the filter holes of the telescopic filter plate 27 and the filter cover 35 are staggered and closed. At this time, the user can operate the water tank to flush the feces generated when using the toilet, and make the feces mixed with charcoal powder and straw powder follow the inclined filter cover 35 through the feces transmission pipe 42 and collect into the feces collection area in the urine and feces collection device 44, so as to realize the separate collection of urine and feces.

[0043] In summary, the feces and urine ecological treatment device for rural dry toilets in cold regions of the present invention can achieve the mixing of biomass powders such as charcoal powder and straw powder with feces through the cooperation of the driving component and the powder blowing component to reduce odor and facilitate mixed fermentation. At the same time, the feces and urine isolation component can collect feces and urine separately and merge them into the feces and urine collection device separately during use to reduce odor, prevent freezing and facilitate subsequent collection and treatment. A manual driving component is used to manually control the powder blowing component according to demand to spread the required amount of biomass powders such as charcoal powder and straw powder on the filter cover of the feces bin through the blowing component, which can be used as a bottom material to reduce the adhesion of feces and the filter cover for easy flushing and cleaning. After the squat toilet is used, the powder is used to cover the feces to reduce odor. After the feces and powder mixture is flushed into the feces and urine collection device, it helps to reduce the water content of the feces for fermentation and reduce the risk of freezing. Driven by the driving component, the blowing impeller set in the powder diversion cover rotates rapidly, which can effectively blow the powder flowing into the material conduit through the opening into the feces bin, so as to achieve the laying of biomass powder on the filter cover 35 and the covering and mixing of feces, which provides convenience for the cleaning inside the feces bin and also helps the collection and fermentation of feces. The anti-skid pedal and the feces and urine isolation component are structurally coordinated to achieve linkage, so that the feces and urine isolation component is triggered by pressing down the anti-skid pedal during use, so that the filter holes of the filter cover and the telescopic filter plate correspond one to one, so that urine is filtered to the bottom of the feces bin and transported to the feces and urine collection device through the urine transmission pipe, effectively realizing the separation of feces and urine, reducing the generation of odor and freezing, and when the anti-skid pedal is released, the reset of the feces and urine isolation component makes the filter holes of the filter cover and the telescopic filter plate staggered and closed, so as to facilitate the flushing and discharge of feces, realize the feces and urine collection, and avoid the odor and discomfort caused by the mixed accumulation of feces and urine.
