[0026] Please see Figure 1-5 The present invention provides the following technical solution: a sewage treatment device for a smart toilet, comprising: a sewage treatment tank 10 and an inlet pipe 11, the inlet pipe 11 being connected to the interior of the sewage treatment tank 10, a partition 12 being installed inside the sewage treatment tank 10, and a discharge port 13 extending from left to right on the partition 12, a solid-liquid separation device being installed on the discharge port 13, the solid-liquid separation device being disposed between the inlet pipe 11 and the discharge port 13 for solid-liquid separation of sewage, the sewage treatment tank 10 being installed inside the smart toilet, and its inlet pipe 11 being connected to the sewage pipe of the smart toilet, the sewage generated by the smart toilet entering the interior of the sewage treatment tank 10 through the inlet pipe 11, and then entering the interior of the solid-liquid separation device.
[0027] The solid-liquid separation device includes a drum 25 rotatably mounted on a partition plate 12. The drum 25 is a cylindrical structure that runs through the left and right sides. Wastewater can enter the inside of the drum 25 through the inlet pipe 11. The outer wall of the drum 25 has an outlet hole 251 that communicates with the inside. A guide plate 252 is installed on the inner wall of the drum 25. The guide plate 252 is used to guide the solids from the inlet pipe 11 to the outlet 13. A transmission component is provided on the outer wall of the drum 25 to drive the drum 25 to rotate. Under the action of centrifugal force, the solids in the wastewater are guided to the outlet 13 by the guide plate 252, while the liquid is discharged to the liquid collection area 15 through the outlet hole 251, thus achieving efficient solid-liquid separation.
[0028] Please see Figure 1-5An annular limiting groove 26 is provided on the inner wall of the partition 12 and the sewage treatment tank 10. An annular limiting block 261 is rotatably provided inside the annular limiting groove 26. The annular limiting block 261 is connected to the roller 25. Through the cooperation of the annular limiting groove 26 and the annular limiting block 261, the roller 25 is ensured to run stably and avoids deviation.
[0029] The transmission components include a gear ring 27 mounted on the outer wall of the drum 25, a drive gear 28 rotatably mounted on the partition plate 12, the drive gear 28 meshing with the gear ring 27, and a drive component provided on the sewage treatment tank 10, which is connected to the drive gear 28. The drive component drives the drive gear 28 to rotate, thereby driving the gear ring 27 and the drum 25 to rotate, ensuring efficient solid-liquid separation.
[0030] The driving component includes a motor 29 mounted on the side wall of the sewage treatment tank 10. The sewage treatment tank 10 has a through hole, and the partition plate 12 has a driving hole corresponding to the through hole. A driving shaft 30 is rotatably mounted inside the through hole. The output end of the motor 29 is connected to the driving shaft 30. One end of the driving shaft 30 that rotates out of the driving hole is connected to the drive gear 28. The motor 29 drives the driving shaft 30 to rotate, and the driving shaft 30 drives the drive gear 28 to rotate.
[0031] The partition 12 divides the sewage treatment tank 10 into a solid collection area 14 and a liquid collection area 15. The liquid collection area 15 is equipped with a filter structure. The roller 25 is installed above the liquid collection area 15. After the roller 25 separates the sewage into solids and liquids, the separated liquid enters the liquid collection area 15 through the outlet hole 251 and is further purified by the filter structure. The separated solids are guided by the guide plate 252 to the discharge port 13 and fall into the solid collection area 14, completing the solid-liquid separation process.
[0032] Please see Figure 1-5 Inside the solid collection area 14, a guide plate 18 is installed. The bottom of the guide plate 18 is connected to the partition plate 12. The partition plate 12 has filter holes 141. The guide plate 18 is a rectangular plate structure with a gradually increasing height from one end near the partition plate 12 to the other end away from the partition plate 12. The guide plate 18 is used to guide the solid to the filter holes 141 to ensure that the filter holes 141 can perform secondary filtration on the solid and filter the liquid remaining on the solid to the liquid collection area 15. The diameter of the filter holes 141 is smaller than the diameter of the water outlet hole 251 to improve the purity of solid-liquid separation.
[0033] The filtration structure includes a coarse filter plate 20 and a fine filter plate 21 installed inside the liquid collection area 15. The coarse filter plate 20 is located above the fine filter plate 21. Wastewater is first initially filtered by the coarse filter plate 20 and then finely filtered by the fine filter plate 21 to ensure that the water quality meets the standards. The diameter of the filter holes on the coarse filter plate 20 is larger than the diameter of the filter holes on the fine filter plate 21, and the diameter of the filter holes on the coarse filter plate 20 is smaller than the diameter of the filter hole 141, thereby performing multi-level filtration of the liquid.
[0034] The coarse filter plate 20 and the fine filter plate 21 are located below the filter holes 141. A sewage discharge pipe 22 is installed on the side wall of the sewage treatment tank 10. A valve is installed on the sewage discharge pipe 22. The filtered sewage can be discharged by opening the valve.
[0035] A blower 16 is installed on one side of the sewage treatment tank 10, and an air outlet 17 is opened on the other side of the sewage treatment tank 10. An odor-removing structure is provided between the blower 16 and the air outlet 17. The air inside the sewage treatment tank 10 is discharged to the outside through the odor-removing structure. An air outlet 142 is opened on the partition 12, and the air outlet 142 corresponds to the air outlet 17. When the blower 16 is started, the blower 16 discharges the air inside the liquid collection area 15 into the deodorization structure through the air outlet 142. The air outlet 142 has a small perforated structure to prevent liquid and solid particles from entering the deodorization structure.
[0036] Please see Figure 1-5 The deodorization structure includes a nano-ultraviolet (UV) lamp 23 installed inside the sewage treatment tank 10. The nano-ultraviolet (UV) lamp 23 is located below the guide plate 18. An activated carbon adsorption plate 24 is installed inside the sewage treatment tank 10. The activated carbon adsorption plate 24 is located below the guide plate 18 and is installed at the end of the nano-ultraviolet (UV) lamp 23 away from the partition plate 12. The activated carbon adsorption plate 24 can effectively adsorb odor molecules. The nano-ultraviolet (UV) lamp 23 can generate ozone, thereby removing the odor from the urine. The nano-ultraviolet (UV) lamp 23 is existing technology and will not be described in detail here.
[0037] The wastewater treatment tank 10 has a discharge port on its side wall. The discharge port is located above the guide plate 18 and is connected to the solid collection area 14. A baffle 19 is installed at the discharge port. The baffle 19 can open or close the discharge port to remove the solids inside the solid collection area 14 for use as fertilizer. The wastewater treatment tank 10 is equipped with a door. When the door can be opened, the filter structure inside the wastewater treatment tank 10 can be cleaned, and the deodorization structure can be replaced or repaired.
[0038] Please see Figure 1-5Working principle: When in use, the inlet pipe 11 is connected to the sewage source in the smart toilet. Sewage flows into the sewage treatment tank 10 and enters the drum 25. The motor 29 drives the drive shaft 30 to rotate, the drive shaft 30 drives the drive gear 28 to rotate, the drive gear 28 drives the gear ring 27 to rotate, and the gear ring 27 drives the drum 25 to rotate. The sewage rotates at high speed inside the drum 25. Under the action of centrifugal force, the solids in the sewage are guided by the guide plate 252 to the discharge port 13 and enter the solid collection area 14, while the liquid is discharged through the water outlet 251 to the liquid collection area 15, realizing efficient solid-liquid separation.
[0039] Solids inside the solids collection zone 14 are guided by the guide plate 18 to the filter holes 141 on the partition plate 12 for secondary filtration. After secondary filtration, the liquid on the solids enters the liquid collection zone 15. The liquid in the liquid collection zone 15 undergoes double filtration through the coarse filter plate 20 and the fine filter plate 21 to ensure water purity. The filtered wastewater is discharged through the sewage pipe 22.
[0040] When the fan 16 is turned on, the fan 16 exhausts the air inside the liquid collection area 15 into the deodorization structure through the air outlet 142. The nano ultraviolet UV lamp 23 deodorizes the air, and the activated carbon adsorption plate 24 can effectively adsorb odor molecules. Then the deodorized air is discharged to the outside to prevent it from polluting the air.
[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
