When the external water pipe is damaged to cause slow leakage of liquid, the water pressure in the external water pipe is slowly reduced, the high-voltage switch is continuously triggered to stop, at the moment, the liquid in the pressure-maintaining air bag box is supplemented into the waterway due to shrinkage of the air bag, the reducing speed of the water pressure in the waterway is slowed down, when the liquid in the pressure-maintaining air bag box cannot supplement the liquid into the waterway, the water pressure in the waterway continuously drops along with the leakage of the water pipe until reaching the triggering threshold value of the low-voltage switch, and the main controller records the first time difference t of the change of the triggering state of the high-voltage switch and the change of the triggering state of the low-voltage switch ₁ The first time difference t ₁ If the water pipe leakage is within the first preset range, the water pipe leakage is considered to be leaked, and a water pipe leakage alarm signal is sent, wherein the first preset range can be set according to experimental data, for example, the time is greater than 10 seconds, and when t ₁ If the water leakage is more than 10 seconds, the water leakage is considered to be the water leakage, and a water leakage alarm signal is sent out, for example, a water leakage signal lamp is lightened and/or a buzzer alarm is sent out.

In some embodiments, when the external water pipe leaks due to rupture, if the rupture is not large enough but is not in a tiny leakage state, the water pressure in the external water pipe is also rapidly reduced, the high-pressure switch is continuously triggered to stop, at this time, the liquid in the pressure maintaining air bag box is replenished into the waterway due to the shrinkage of the air bag, and the pressure maintaining air bag box is only reduced in a short time due to the rapid water leakage in the external water pipeThe water pressure in the water way is reduced rapidly along with the rupture of the water pipe when the liquid in the pressure maintaining air bag box cannot supplement the liquid in the water way, the water pressure in the water way reaches the trigger threshold value of the low-voltage switch in a short time, and the main controller records a second time difference t between the high-voltage switch and the low-voltage switch which is triggered ₂ The second time difference t ₂ And if the water pipe is broken within the second preset range, sending out a water pipe breakage alarm signal.

In some embodiments, when the second electromagnetic valve of the fresh water tank is opened to supplement water normally, the water pressure in the external water pipe is reduced rapidly, the high-voltage switch is continuously triggered to be stopped, at this time, the liquid in the pressure maintaining air bag box is supplemented into the waterway due to shrinkage of the air bag, the pressure maintaining air bag box only can reduce the reducing speed of the water pressure in the waterway in a transient manner due to the very fast water flow in the external water pipe, when the liquid in the pressure maintaining air bag box cannot supplement the liquid in the waterway, the water pressure in the waterway reaches the trigger threshold of the low-voltage switch in a very short time, and the main controller records the third time difference t between the high-voltage switch and the low-voltage switch which is triggered ₃ The third time difference t ₃ And if the water is in the third preset range, the water is considered to be normally replenished, no alarm signal is sent out, and a normal replenishing signal can be sent out. Wherein the third preset range can be set according to experimental data, such as 0-3 seconds, when t ₃ And when the water is in the range of 0-3 seconds, the water is considered to be normally replenished, a normal replenishing signal is sent out, for example, a normal replenishing signal lamp is turned on, and the normal replenishing signal lamp is turned off after the replenishing is finished.

In some embodiments, when the external water pipe is broken to cause rapid leakage of liquid, at this time, the water pipe is broken to cause serious water leakage, and the triggering interval of the high-low pressure trigger switch is close to that of the second electromagnetic valve when the second electromagnetic valve is opened during normal water supplementing, for example, the trigger interval is also in a third preset range, and the main controller cannot judge whether the water pipe is normal water supplementing or the water pipe is broken, at this time, the control can be controlled by the following control logic. The master box is further configured to: the second electromagnetic valve is closed in a first preset time period, and the first electromagnetic valve is closed in a second preset time period, wherein the second preset time period at least partially overlaps with the first preset time period; and in the time period of which the second preset time period is overlapped with the first preset time period, the high-voltage switch is continuously triggered, and the water pipe is judged to be not broken. The at least partial overlap may be a portion of the second preset time period being the first preset time period.

As shown in fig. 12, whether or not the water pipe is broken can be described by a timing chart. When the water level of the clean water tank reaches the detection position of the anhydrous detection sensor (such as the anhydrous Hall sensor), the second electromagnetic valve of the clean water tank is opened, the water in the pipeline is released, the pressure in the pipeline is reduced along with the release, the low-pressure switch is triggered, the first electromagnetic valve is opened, the first electromagnetic valve is 1 second for example, the water in the tap is fed into the pipeline, the second electromagnetic valve is closed, the second electromagnetic valve is 1.5 seconds for example, the first electromagnetic valve is closed after the preset time, the first electromagnetic valve is 3 seconds for example, the first electromagnetic valve is closed after the second electromagnetic valve is closed, the first electromagnetic valve is closed after the water is continuously fed for 1.5 seconds, the high pressure in the pipeline is maintained in the time period, namely, a period of water is filled before each water filling, for example, 2 seconds, whether the high pressure state can be maintained in the pipeline is detected, the first electromagnetic valve is opened after the first electromagnetic valve is closed for 1 second for example, the 4 seconds, the first electromagnetic valve is recorded as the high pressure in the pipeline is closed for 1 second if the pipeline is not broken, the pipeline is high pressure in the pipeline is not broken, the high pressure state can be judged if the pipeline is broken, the high pressure state cannot be reached if the high pressure state is not is reached in the time period. The second solenoid valve is then opened to begin normal replenishment until the fresh water tank is full, for example, at 5 seconds, and closed. Therefore, the problem that water leakage is more serious due to continuous water supplementing under the condition that a water pipe is broken can be avoided.
