After the infiltration is completed, ozone water is prepared immediately, and a user flushes water with the ozone water after using the toilet 100. Ozone water is prepared in real time for flushing, and the situations of ozone escape and ozone water concentration attenuation are reduced.

In one embodiment, the toilet bowl 100 further comprises a tap water port 111, a first water inlet valve 112 and a second water inlet valve 113, the ozonated water preparation device 130 and the brush ring water storage tank 103 are both communicated with the tap water port 111, the tap water port 111 can be used for connecting an external water pipe to input tap water, the first water inlet valve 112 is arranged on a waterway between the ozonated water preparation device 130 and the tap water port 111, and the second water inlet valve 113 is arranged on a waterway between the brush ring water storage tank 103 and the tap water port 111; the first water inlet valve 112 is opened in response to the preparation signal to communicate the ozonated water preparation device 130 and the tap water inlet 111; the second water inlet valve 113 is closed in response to the wetting signal to disconnect the brush ring storage tank 103 from the tap water port 111.

As an example, when the sensor 120 senses that a user sits on the seat ring 110 for more than 30S, the controller 140 outputs an immersion signal, the brush ring opening and closing valve 109 responds to the immersion signal and communicates a water path between the brush ring water storage 103 and the brush ring water outlet 101, the second water inlet valve 113 closes in response to the immersion signal to disconnect the brush ring water storage 103 and the tap water outlet 111, and the controller 140 sends a preparation signal, and the first water inlet valve 112 opens in response to the preparation signal to communicate the ozonated water preparation device 130 and the tap water outlet 111 until a stop condition is met, so as to stop preparing ozonated water. For example, the ozone water preparation is stopped until the brush ring water storage tank 103 is filled with ozone water. Specifically, the toilet bowl 100 may further include a water level sensor installed in the brush ring water storage tank 103, and the controller 140 determines whether the brush ring water storage tank 103 is filled with ozone water according to a sensing signal output from the water level sensor.

In the present embodiment, the ozonated water may be produced by an electrolytic method, in which tap water passing through the first water inlet valve 112 is produced into ozonated water by passing through the cathode and the anode of the ozonated water producing device 130. Meanwhile, the second water inlet valve 113 is closed, so that the ozone water in the brush ring water storage tank 103 is prevented from being diluted.

In one embodiment, the toilet 100 further includes a flush switch 108, the flush switch 108 is in signal connection with the controller 140, the flush switch 108 is configured to generate a flush signal according to a user operation, and the controller 140 is configured to control the brush ring switch valve 109 to be opened after receiving the flush signal, so as to flush water through ozone water stored in the brush ring storage 103. For the specific structure of the flush switch 108, reference may be made to the related descriptions of the above embodiments, and details are not repeated herein.

At this time, after the user operates the water flush, the toilet 100 senses that the user sits on the seat 110. If the user is seated on the seat 110 after the flush, the user may not finish using the toilet 100 and continue using the same, while keeping the first inlet valve 112 open, to prepare the ozone water for the next flush.

In one embodiment, the controller 140 is further configured to output a closing signal of the first water inlet valve 112 when the flush signal is issued and the sensing signal of the sensor 120 is not received, and the first water inlet valve 112 is closed in response to the closing signal of the first water inlet valve 112. At this time, after the user operates to flush, the user no longer sits on the seat ring 110, the user finishes using the toilet 100, at this time, the first water inlet valve 112 is closed and the second water inlet valve 113 is opened, and the tap water enters the brush ring water storage tank 103 through the second water inlet valve 113 to prepare for the next use of the user.

The toilet bowl 100 provided by the present application can instantly prepare ozone water for flushing according to the time length of a user sitting on the seat 110. Before the bath, if the user sits on the seat ring 110 for a long time longer than preset time, the inner wall of the toilet 100 is soaked by tap water in the brush ring water storage tank 103, the condition that excrement is adhered to the inner wall of the toilet 100 is reduced, and the user can clean the toilet 100 conveniently. The inner wall of the toilet 100 is washed by the ozone water through the brush ring water outlet 101, so that the toilet 100 can be effectively sterilized, and meanwhile, the ozone water can play a role in deodorization, and the toilet environment of a user is improved.
