The microwave induction assembly comprises an antenna module, wherein the antenna module comprises a transmitting antenna and a receiving antenna, the transmitting antenna is used for transmitting electromagnetic waves, the receiving antenna is used for receiving reflected electromagnetic waves, the transmitting antenna is used for transmitting the electromagnetic waves forwards, the electromagnetic waves are detected by the receiving antenna after being reflected, the detection data are generated, and the detection data are sent to the controller.
The microwave induction component is positioned on the rear wall of the body, and a cavity for accommodating the microwave induction component is arranged on the rear wall. The structure of this cavity can be regarded as a sunk structure of back wall in fact, and this cavity department wall thickness is thinner, and is thinner than adjacent position promptly, can make things convenient for the installation of microwave response subassembly through setting up this cavity, and in addition, thicker wall thickness can influence the transmission distance of electromagnetic wave, but too thin can influence the bulk strength of urinal, can also avoid causing too big influence to the transmission of electromagnetic wave on the basis of guaranteeing urinal bulk strength through setting up this cavity.
As shown in fig. 2a, under normal conditions and under the condition of no water blockage, when the accumulated water in the water does not cover the microwave emission path, the electromagnetic wave emitted by the microwave sensing assembly sequentially penetrates through the air, the ceramic and the air to reach the human body, wherein the difference between the dielectric constants of the air and the ceramic is not large, but the difference between the dielectric constants of the air and the human body is large, and the human body reflects a large amount of microwaves, so that the microwave sensing assembly can normally detect the spatial position of the human body.
Under the condition of water blockage, as shown in fig. 2b, at the moment, the transmission path of the electromagnetic wave is shielded by the accumulated water at the trap of the urinal, the electromagnetic wave sequentially passes through the air, the ceramic and the water and can hardly reach the human body, wherein the difference between the dielectric constants of the air and the ceramic is not large, the microwave can penetrate through the water, but the difference between the dielectric constants of the ceramic and the water is large, and the microwave can hardly penetrate through the water, so that the human body can not be accurately detected.

And S22, controlling the flushing assembly according to the first distance.
In implementation, first, the first distance is determined, where the determination refers to comparing the first distance with a preset jam distance threshold value a. The value of the preset blocking distance threshold A is not more than the distance between the foremost end of the urinal body and the microwave induction assembly and is more than the distance between the microwave induction assembly and accumulated water of the urinal when the urinal is blocked.
When the first distance is smaller than the preset blocking distance threshold value A, the urinal is judged to be blocked, and the flushing component is controlled not to flush water at the moment so as to avoid sewage overflow.
Through the control, whether the blockage occurs can be accurately judged, the action of the flushing assembly is controlled according to the blockage condition, namely the controller stops flushing under the condition of flushing, and the corresponding flushing instruction is refused to be executed under the condition of not flushing so as to achieve the effect of avoiding the overflow of sewage.

and S23, controlling the flushing component to perform pre-flushing.
By re-determining the first distance, when the first distance is greater than the preset blockage distance threshold a and less than the first distance threshold T _ in, as shown in fig. 8, the flushing assembly is controlled to perform pre-flushing, or pre-wet the surface of the urinal. Through the operation, the surface of the urinal can be pre-wetted, urine is prevented from directly contacting the surface, and the urine can be conveniently flushed clean after subsequent flushing.
In another specific implementation manner of this embodiment, the following steps are further included, as shown in fig. 9.
And S24, controlling the flushing component to flush again.
And when the first distance is greater than a second distance threshold value T _ out, controlling the flushing component to flush again. At this time, the actual scenario generally corresponds to the stage that the user leaves after urinating, and the flushing assembly is controlled to flush again to clean the surface of the urinal. The urinal can be cleaned by flushing water again, so that the urinal keeps clean and sanitary, and dirt on the surface of the urinal is avoided.
