The bottom wall of the inner cavity of the frame body 201 is fixed with not less than two constant temperature heating wires 202. A stainless steel filter screen 203 is fixed inside the frame body 201. A sealing cover 204 is fixed on the upper surface of the frame body 201 by bolts. An air inlet pipe 205 is communicated with the upper side of the left side of the frame body 201. A blower 206 is fixed on the upper surface of the sewage tank body 1. A connecting pipe 207 is communicated with the right side of the frame body 201. The right side of the connecting pipe 207 is fixedly connected with the air inlet end of the blower 206.

[0026] In this embodiment, the drying mechanism 2 further includes an input pipe 208 fixed to the air outlet end of the fan 206. The outer side of the right side of the input pipe 208 is connected to a first electromagnetic valve 209. A docking pipe 210 is connected to the inside of the first electromagnetic valve 209. An air outlet arc plate 211 is fixed to the back wall of the inner cavity of the sewage tank body 1. After cleaning, by opening the third electromagnetic valve, the water for cleaning inside the sewage tank body 1 is discharged through the first drain pipe and the second drain pipe. Then, turn on no less than two constant temperature heating wires 202, the fan 206 and the first electromagnetic valve 209. The outside air flows into the inside of the frame body 201 through the air inlet pipe 205. Then, the stainless steel filter screen 203 filters the dust in the incoming air. The bottom end of the docking pipe 210 penetrates through the sewage tank body 1 and is connected to the upper surface of the air outlet arc plate 211. The stainless steel filter screen 203 is located above no less than two constant temperature heating wires 202. The air inlet pipe 205 is located above the stainless steel filter screen 203. The connecting pipe 207 is located below the stainless steel filter screen 203.

[0027] It should be noted that the incoming air is filtered and then heated to a constant temperature by no less than two constant temperature heating wires 202. Then, it flows into the inside of the air outlet arc plate 211 through the input pipe 208 and the docking pipe 210. The air outlet arc plate 211 discharges air evenly and dries the water stains inside the sewage tank body 1. When the inside of the sewage tank body 1 is dried, the circulating air is discharged through the first drain pipe and the second drain pipe. Thus, after cleaning the inside of the sewage tank, it is convenient to dry the inside of the sewage tank. The front of the air outlet arc plate 211 is provided with no less than two air outlet holes.

[0028] Please refer to Figure 4 , in order to clean the inside of the sewage tank body 1, in this embodiment, the cleaning mechanism 3 includes a water pump 301 fixed to the left side of the upper surface of the sewage tank body 1. A fixed pipe 302 is fixed to the input end of the water pump 301. The outer side of the left side of the fixed pipe 302 is connected to a second electromagnetic valve 303. A water inlet pipe 304 is connected to the inside of the second electromagnetic valve 303. When it is necessary to clean the inside of the sewage tank body 1, the left side of the water inlet pipe 304 can be connected to an external water source pipe. Then, turn on the second electromagnetic valve 303, the water pump 301 and the fourth electromagnetic valve.

[0029] In this embodiment, the cleaning mechanism 3 includes a connecting pipe 305 fixed to the output end of the water pump 301. A delivery pipe 306 is fixed to the top wall of the inner cavity of the sewage tank body 1 through a mounting bracket. The lower surface of the delivery pipe 306 is rotatably connected through bearings to no less than two rotating nozzles 307. The outer sides of the rotating nozzles 307 are connected to no less than two water outlet heads 308. The bottom end of the connecting pipe 305 penetrates through the sewage tank body 1 and is connected to the upper surface of the delivery pipe 306.

[0030] It should be noted that the water in the outer water source pipe flows into the inside of the delivery pipe 306 through the water inlet pipe 304, the fixed pipe 302 and the connecting pipe 305, then flows into the inside of no less than two rotating nozzles 307, and then is ejected from no less than two water outlets 308 to clean the inside of the sewage tank body 1. The rotating nozzle 307 can rotate while spraying water, enabling automatic cleaning. The air pressure inside the sewage tank body 1 is discharged through the U-shaped pipe.

[0031] The working principle of the above embodiment is as follows:

[0032] (1) When it is necessary to clean the inside of the sewage tank body 1, the left side of the water inlet pipe 304 can be connected to the outer water source pipe, and then the second electromagnetic valve 303, the water pump 301 and the fourth electromagnetic valve are opened. The water in the outer water source pipe flows into the inside of the delivery pipe 306 through the water inlet pipe 304, the fixed pipe 302 and the connecting pipe 305, then flows into the inside of no less than two rotating nozzles 307, and then is ejected from no less than two water outlets 308 to clean the inside of the sewage tank body 1. The rotating nozzle 307 can rotate while spraying water, enabling automatic cleaning. The air pressure inside the sewage tank body 1 is discharged through the U-shaped pipe.

[0033] (2) After cleaning, by opening the third electromagnetic valve, the water for cleaning inside the sewage tank body 1 is discharged through the first drain pipe and the second drain pipe. Then, no less than two constant temperature heating wires 202, the fan 206 and the first electromagnetic valve 209 are opened. The outside air flows into the inside of the frame body 201 through the air inlet pipe 205. Then, the stainless steel filter screen 203 filters the dust in the inflowing air. After the inflowing air is filtered, it is heated to a constant temperature by no less than two constant temperature heating wires 202, and then flows into the inside of the air outlet arc plate 211 through the input pipe 208 and the docking pipe 210. The air outlet arc plate 211 blows out air evenly to dry the water stains inside the sewage tank body 1. When the inside of the sewage tank body 1 is dried, the flowing air is discharged through the first drain pipe and the second drain pipe. Thus, after cleaning the inside of the sewage tank, it is convenient to dry the inside of the sewage tank.
