The universal communication tube 13 is installed on the handheld operator 7 and communicated with the filler turning and sucking device 8 through the internal curved pipe 71 of the handheld operator 7. In this way, the filler sucked by the filler turning and sucking device 8 is transferred to the collection area of ​​the filler collecting box 2 under the push of the negative pressure airflow. The handheld operator 7 consists of a curved pipe 71, an operation button panel 72 and a handle 73. The operation button panel 72 is located below the curved pipe 71 and is connected to the control box 4 by a control cable 76. The handle 73 is located above the curved pipe 71 for holding during operation.

[0027] The filler turning suction device 8 is composed of a sleeve 81, a spiral lifting blade 82, a transmission shaft 83, a loosening claw connection seat 84, a loosening claw 85, a fastening bolt 86, a coupling 87, a sleeve 88 and a fixed bracket 89.

[0028] The reducer 14 is connected to the base 75 by bolts and then mounted on the mounting base 74 fixed on the elbow 71 .

[0029] When the reducer 14 is powered on, the loosening claw 85 breaks up the compacted filler by rotating and cutting, and under the impetus of the negative pressure suction airflow and the lifting movement of the spiral lifting blades, the filler is quickly lifted up and transported to the curved pipe 71, and then continues to be driven by the negative pressure suction airflow, passes through the universal connector 13, and moves along the first suction pipe 15 to the collection area of ​​the filler collection box 2. Furthermore, one end of the sleeve 81 is flush with the lower part of the loosening claw 85, and a half-edge gap is opened on one side to facilitate expanding the contact area with the filler.

[0030] The maintenance personnel, in a standing position, holds the handle 73 and presses the corresponding button on the operation button panel 72 to turn on the exhaust fan 5 and the first electric valve 9, thereby starting the stuffing turning suction device 8 to clean the stuffing in the main part of the ecological toilet. After the suction is completed, the corresponding button on the operation button panel 72 is pressed to turn off the exhaust fan 5 and the first electric valve 9.

[0031] The fixing bracket 89 is sleeved on the filler turning and conveying aspirator 8, and is used to integrate and fix the suction nozzle 11 and the flushing nozzle 12, so as to facilitate flexible switching and operation. The fixing bracket 89 is in the shape of a flat plate, and has three holes. The filler turning and conveying aspirator 8 is inserted in the middle for fixing. There are long strip holes on both sides for inserting the suction nozzle 11 and the flushing nozzle 12.

[0032] One end of the second suction pipe 16 is connected to the second electric valve 10, and the other end is connected to the suction nozzle 11. The suction nozzle 11 is located on one side of the filler turning suction device 8. It can be inserted into the fixed bracket 89 when not in use.

Finally, insert the suction nozzle 11 back into the corresponding socket of the fixed bracket 89.

[0033] A water delivery pump 6 is installed outside the water storage tank 3. The water delivery pump 6 is generally a micro diaphragm pump, with the pump head facing upward or downward, and the water inlet end is connected to the water outlet hole of the lower wall of the water storage tank 3 through the second water delivery hose 61. The water outlet end is connected to the flushing nozzle 12 through the first water delivery hose 18. The flushing nozzle 12 can be inserted into the fixed bracket 89 when not in use.

[0034] When it is necessary to clean the toilet bowl with pressure water flow, one hand holds the handle 73, and the other hand pulls out the flushing nozzle 12 from the fixed bracket 89, and presses the corresponding button on the operation button panel 72 to start the water pump 6, that is, flushing. After flushing and cleaning, press the corresponding button on the operation button panel 72 to turn off the water pump 6. Finally, the flushing nozzle 12 is inserted back into the corresponding socket of the fixed bracket 89.

[0035] The stuffing collection box 2 is composed of a lower box body 201 and an upper box body 202. The exhaust fan 5 is installed at the top center position outside the upper box body 202, and the air inlet pipe of the exhaust fan 5 extends into the upper box body 202. An air collecting cylinder 217 is set at the top center position in the upper box body 202, and is combined with the filter 216 below to form a negative pressure air collecting area A. The pipe opening of the air inlet pipe extending into the upper box body 202 is located in the negative pressure air collecting area A. The air collecting cylinder 217 is connected to the filter 216 below by threads, which is convenient for the replacement and disassembly of the filter 216.

[0036] A support tube 214 is provided in the middle of the lower box 201. The surroundings and bottom of the support tube 214 are mesh-shaped, and there is a gap between the support tube 214 and the inner wall of the lower box 201. The support ring 210 is welded and fixed to the middle of the lower box 201. Thus, the support ring 210, the support tube 214 and the lower box 201 form another negative pressure area B. The negative pressure area B is connected to the negative pressure gas collection area A through the lower connecting pipe 204, the connecting sleeve 205 and the upper connecting pipe 206.

[0037] The filter bag 211 is placed in the support tube 214 and supported by the support tube 214, intercepting solid fillers from the inside to the outside and filtering out gas and moisture. The edge of the filter bag 211 is placed on the support ring 210 and is compressed, fixed and sealed by a pressure ring 212 and a set of second fastening bolts 213.

[0038] The lower connecting pipe 204 , the connecting sleeve 205 , the upper connecting pipe 206 , the first pipeline 910 and the second pipeline 101 connected to the negative pressure gas collecting area A are arranged on both sides of the filler collecting box 2 .

[0039] A baffle 215 is provided outside the negative pressure gas collecting area A at the top of the upper box 202, extending from top to bottom to the upper part of the lower box 201, close to the side area where the first pipeline 910 and the second pipeline 101 are arranged, for changing the airflow direction of the first pipeline 910 and the second pipeline 101, changing the airflow movement from horizontal to downward, facilitating the sedimentation of the solid filler entrained in the airflow, and realizing gas-solid separation, so as to prevent the airflow from carrying the filler and directly impacting the filter 216.

[0040] In the stuffing collection box 2, except for the negative pressure gas collection area A and the negative pressure area B, the other areas are the collection area C. When the stuffing collection box 2 is operating normally, the exhaust fan 5 extracts air from the negative pressure gas collection area A, so that negative pressure is formed in the negative pressure gas collection area A and the negative pressure area B, driving the airflow from the first pipe 910 or the second pipe 101 into the collection area C. The airflow entrained with the stuffing first hits the baffle 215, and the running direction is changed from horizontal to downward movement. The solid stuffing entrained in the airflow sinks into the filter bag 211 under the action of gravity. After being filtered by the filter bag 211, part of the gas enters the negative pressure area B, and finally enters the negative pressure gas collection area A through the lower connecting pipe 204, the connecting sleeve 205, and the upper connecting pipe 206. Another part of the gas returns and moves upward, and enters the negative pressure gas collection area A after being filtered by the filter 216. All gases entering the negative pressure gas collection area A are discharged from the outside of the stuffing collection box 2 through the exhaust fan 5.

[0041] The lower box 201 and the upper box 202 are connected by 3-4 lock buckles 203 evenly distributed, and the seal is achieved by pressing the sealing ring 207. When it is necessary to take out the stuffing collected in the stuffing collection box 2 and replace the filter bag, open the lock buckle 203, and remove the upper connecting pipe 206 from the connecting sleeve 205, and the upper box 202 can be opened. Then loosen the second fastening bolt 213, remove the pressure ring, and take out the filter bag 211 filled with stuffing. At the same time, if the filter 216 needs to be replaced, the filter 216 can also be screwed off from the air collecting cylinder 217 and replaced with a new filter. After the replacement is completed, the upper box 202 is reinstalled in reverse order, the lock buckle 203 is locked, and the upper connecting pipe 206 is installed in the connecting sleeve 205, that is, the lower box 201 and the upper box 202 are closed and the sealing ring 207 is pressed to achieve sealing.

[0042] Furthermore, considering that the eco-toilet may emit odors when the filling is cleaned and discharged from the exhaust fan outlet pipe, affecting the environment in the compartment, an exhaust pipe 17 is specially provided. One end of the exhaust pipe 17 is connected to the exhaust fan outlet pipe, and the other end can be extended out of the compartment for emptying as needed. When not in use, the exhaust pipe 17 can be coiled on the top of the upper box body 202; thereby achieving a good user experience in the cleaning and replacement operation of the eco-toilet filling.

[0043] When the packing in the ecological toilet needs to be replaced, it is often in a compacted state. Conventional cleaning methods are time-consuming and labor-intensive, and the efficiency is relatively low. The packing cleaning device for ecological toilets in the present application is designed with a loosening claw crushing structure in the packing turning and suction device. The loosening claw is driven by a reducer to rotate and crush the compacted packing. Then, under the push of negative pressure airflow, it is vertically lifted with the aid of a spiral lifter, and finally the packing is transferred to the packing collection box. The entire cleaning process is simple and efficient; and it meets the design requirements of a compact structure and flexible installation, which is very suitable for applications in train compartment toilets where the space is very limited.

[0044] There are many dead corners in the ecological toilet due to the complex stirring device installed. In order to further improve the cleaning effect, the cleaning device is also equipped with a small-caliber suction nozzle, which is specially used to clean the residual fillers in some dead corners in the toilet. The suction port of the suction nozzle is flat, which is convenient for sucking fillers from narrow dead corners. The rear end is round, which is convenient for connecting hoses and gas circulation; it realizes dual suction in one machine, with large diameter for large materials and small diameter for small materials, improving the overall cleaning efficiency.

[0045] When some fillers adhere firmly to the toilet and form stubborn stains, this cleaning device is also equipped with a pressure water nozzle for flushing with high-pressure water. By setting up a water storage tank and a micro diaphragm pump, it can automatically absorb water and automatically output water under pressure. The water volume is small and the pressure is high, so as to achieve a satisfactory flushing and cleaning effect.

[0046] Considering the convenience of operation, a handheld operator is specially designed for cleaning and operation nearby; the handheld operator consists of a bend, an operation button panel and a handle. The operation button panel is located below the bend, and is connected to the control box by a control cable. The handle is located above the bend for holding during operation. According to the needs of turning and crushing the compacted filler, cleaning the filler in the dead zone corner and cleaning the stubborn stains, directly select the corresponding button for opening and closing operations, eliminating the trouble of frequently entering and exiting the bathroom to operate the button. The handheld operator is structurally integrated based on the main pipeline, with a small size and convenient operation.

[0047] Considering the convenience of operation, the cleaning device is provided with a fixed bracket made of hard rubber, which is mounted on the filler turning and sucking device, and the suction nozzle and the flushing nozzle are integrated and fixed together, so as to facilitate flexible switching and operation. The fixed bracket is in the shape of a flat plate with three holes. The filler turning and sucking device is inserted in the middle for fixing. There are long strip holes on both sides for inserting the suction nozzle and the flushing nozzle.

[0048] According to the characteristics of the ecological toilet filler that needs to be cleaned, it is powdery, easy to settle, soft in texture, and easy to adhere. The filter bag collection is designed, and the filler collection box is divided into a lower box and an upper box. A negative pressure gas collection area is set in the center of the top of the upper box, and a filter is provided. The lower box is provided with a support cylinder, and the surrounding and bottom of the support cylinder are mesh-shaped. The filter bag is placed in the support cylinder, which intercepts solid fillers from the inside to the outside and filters out gas and moisture. The support ring, the support cylinder and the lower box form a negative pressure area that is connected to the negative pressure gas collection area; the upper box is provided with a baffle, which is used to change the direction of the inhaled airflow, and change the airflow movement from horizontal to downward, so as to facilitate the sedimentation of the solid fillers entrained in the airflow and realize gas-solid separation; the solid fillers entrained in the airflow sink into the filter bag under the action of gravity.

[0049] The cleaning device of the present application has low maintenance and operation difficulty, and has the functions of loosening by loosening claws and suction of fillers by negative pressure. It can easily clean the fillers in the ecological toilet, reduce manual contact, and improve cleaning efficiency.
