Description
Technical Field
[0001] The present invention relates to the technical field of intelligent toilets, and in particular to a flushing system for an intelligent toilet and an intelligent toilet. Background Art
[0002] In modern home life, as a core sanitary ware, the performance of the flushing system of a toilet is directly related to user experience, hygiene conditions and resource utilization efficiency. Traditional toilets generally adopt a gravity flushing mechanism, where the water in the water tank is released by gravity to discharge sewage. This method has significant defects. On the one hand, it cannot accurately identify the type of user excretion. Whether the user urinates or defecates, the same amount of water and water flow mode are used for flushing. This results in a waste of water resources when urinating, as the excessive flushing water is unnecessary; while when defecating, sometimes the flushing water volume or water flow impact is insufficient, making it difficult to completely remove feces, and the remaining dirt from excretion is likely to remain on the inner wall of the toilet, forcing the user to flush multiple times, further increasing water consumption and also increasing the user's waiting time and operation cost. Summary of the Invention
[0003] In order to solve the above-mentioned existing technical problems, the present invention provides a flushing system for an intelligent toilet and an intelligent toilet.

[0006] The detection device includes a sound sensor and an infrared sensor, the sound sensor is arranged on the outer wall of the toilet bowl, and the infrared sensor is arranged on the inner side surface of the toilet lid;
[0007] The control panel is arranged on one side of the toilet, a controller is arranged in the control panel, and the first valve and the detection device are both electrically connected to the controller;
[0008] The controller is provided with an excretion recognition module, a user recognition module and an automatic flushing module; the excretion recognition module recognizes whether excretion has occurred and the type of excretion through the audio data collected by the sound sensor; the types of excretion include urination and defecation, and the frequencies of the sounds generated by urination and defecation are different, and the type of excretion is judged by feature recognition; the user recognition module detects the user status through the infrared sensor; the infrared sensor can detect the distance of the user to judge whether the user is standing in front of the toilet or sitting on the toilet.
[0009] When the infrared sensor provided on the toilet lid detects that a person has left, the automatic flushing module controls the first valve to open, and the water in the water tank enters the annular flushing bracket through the first pipeline and is sprayed out from the water outlet to flush the toilet bowl.
[0010] The automatic flushing module includes a flow control unit, the flow control unit changes the flushing flow by controlling the valve opening of the first valve, and the flow control unit adjusts the flushing flow according to the type of excretion recognized by the excretion recognition module. When defecation is detected, a large flow of water is used for flushing; the first valve is opened for the same duration each time.
[0011] Further, it also includes an emergency flushing pipeline, the emergency flushing pipeline connects the water tank and the annular flushing bracket, and a manual switch valve is provided on the emergency water supply pipeline. When the system is powered off and automatic flushing cannot be performed, the user can directly open the manual switch valve to perform a flushing operation.
