Description

Technical Field

[0001] The utility model belongs to the technical field of toilets, in particular to a cutting and anti-clogging intelligent toilet. Background Art

[0002] The connection between the water inlet and the drain outlet of the toilet forms a curved structure with a small diameter and a large depth. It is easy for debris to fall and cause the toilet to be blocked. When the pipe is blocked, three methods are often used to solve it. The first is to use chemicals to corrode the debris, but it cannot be guaranteed to have a beneficial effect on all debris. The second is to use a rubber suction cup to suck up the debris. The suction force generated by the rubber suction cup is relatively small. If it touches the pipe wall during the process of sucking up the debris, the debris will be separated from the suction cup, and repeated suction is required, affecting the use of the toilet. The third is to use hard objects such as wire to hook it, but because it is a curved structure, it is easy to push the debris inward, increasing the difficulty of unblocking. After the debris is blocked, the excrement cannot be flushed away, causing odor and affecting the surrounding environment. Utility Model Content

[0029] The top of the pump head 8 is provided with a cutting mechanism mounting groove 12, and the bottom of the pump head 8 is provided with a motor mounting groove 13. The cutter head 10 is fixed to the bottom of the cutting mechanism mounting groove 12, and the motor mounting groove 13 is sleeved on the top of the motor 7. The pump head 8, the cutting mechanism mounting groove 12 and the motor mounting groove 13 are integrally formed.

[0030] The sewage holding chamber 2 is arranged at the top front end of the toilet seat 1 and the opening is arranged upward. The bottom of the sewage holding chamber 2 is provided with an extension tube 14 extending toward the rear side of the toilet seat 1. The corner of the extension tube 14 is a smooth arc surface, which facilitates the smooth flow of excrement to the sewage pipe 5.

[0031] The drain pipe 5 is N-shaped, and the exhaust valve 6 is located at the highest point of the drain pipe 5. Gas can gather at the top of the N-shaped drain pipe 5 and then be smoothly discharged through the exhaust valve 6. A first mounting groove 15 is provided at one end of the drain pipe 5, which cooperates with the extension pipe 14. The first mounting groove 15 is mounted outside the extension pipe 14 and is fixedly connected thereto. The other end of the drain pipe 5 is provided with a second mounting groove 16 that cooperates with the cutting mechanism mounting groove 12. The second mounting groove 16 is mounted outside the cutting mechanism mounting groove 12 and is fixedly connected thereto. The first mounting groove 15 is sealed to the extension pipe 14, and the second mounting groove 16 is sealed to the cutting mechanism mounting groove 12.

[0032] To accommodate rear-drain toilets, a drainage port 3 can be positioned on the rear sidewall of the toilet seat 1. This port 3 comprises a detachably connected inner port 17 and an outer port 18. The inner port 17 connects to the outlet of the cutting pump 4, while the outer port 18 is threadedly attached to the outer portion of the inner port 17. This detachable port 3 facilitates disassembly, inspection, and maintenance. The port 3 features a flared structure, with a diameter larger than that of the cutting pump 4 outlet, which expedites the discharge of waste.

[0033] When the device is in operation, an extension tube 14 from the toilet's sewage chamber 2 is directly connected to the cutting pump 4 via the sewage pipe 5. Air in the pipe is evacuated via the exhaust valve 6, allowing water to easily flow into the cutting mechanism 9 at the inlet of the cutting pump 4. When foreign matter, such as towels or wet wipes, is encountered, it is carried along by the water flow into the cutting mechanism 9. A powerful cutting blade 11 and a cutter disc 10 are mounted within the cutting mechanism's mounting slot 12. The cutter disc 10 is stationary, while the blade 11 rotates with the output shaft of the motor 7. The blade 11 and cutter disc 10 cooperate to crush the foreign matter.

[0034] During use, the smart toilet controls the flushing process through the toilet controller 21. The controller 21 sends a signal to the main board that controls the cutting pump 4. After receiving this signal, the main board that controls the cutting pump 4 delays the start-up based on the default time for water to flow to the water inlet of the pump head 8, and discharges the water and foreign matter. The working time of the cutting pump 4 each time is determined by the flushing volume. In the event of a power outage, the cutting pump 4 does not work, but when the toilet is in use, the water can also flow naturally along the sewage pipe and pump head. Example 2:
