After the water tank is reset for the first time, after the circuits and the pipelines of the water tank assembly and the main control box are connected, the control button of the main control box is firstly opened, the first electromagnetic valve of the main control box is opened for a period of time and then closed, for example, the first electromagnetic valve and the second electromagnetic valve are both closed, a water channel between the first electromagnetic valve and the second electromagnetic valve is filled with clear water, at the moment, the water channel is in a high-pressure state, the high-pressure switch is in a continuous trigger state, and the first electromagnetic valve is also in a response high-pressure switch state and closed. When the external water pipe causes liquid to slowly leak due to damage, the water pressure in the external water pipe is slowly reduced, the continuous trigger state of the high-pressure switch is stopped, at the moment, the liquid in the pressure maintaining air bag box is supplemented into the water channel due to the contraction of the air bag, the reduction speed of the water pressure in the water channel is slowed down, when the liquid in the pressure maintaining air bag box cannot supplement the liquid in the water channel, the water pressure in the water channel continuously reduces along with the leakage of the water pipe until the trigger threshold value of the low-pressure switch is reached, and the main controller records the first time difference t between the change of the trigger state of the high-pressure switch and the change of the trigger state of the low-pressure switch ₁ The first time difference t ₁ And in a first preset range, the water pipe is considered to be leaked, and a water pipe leakage alarm signal is sent out, wherein the first preset range can be set according to experimental data, for example, more than 10 seconds, and when t is up to ₁ And when the time is more than 10 seconds, the water pipe is considered to be leaked, and a water pipe leakage alarm signal is sent out, for example, a water pipe leakage signal lamp is turned on and/or a buzzer alarm is sent out.

In some implementationsIn the embodiment, when the external water pipe causes liquid leakage due to rupture, if the rupture is not large enough but not in a micro-leakage state, the water pressure in the external water pipe can also be rapidly reduced, the continuous triggering state of the high-pressure switch is stopped, at the moment, the liquid in the pressure maintaining air bag box is supplemented into the water channel due to the contraction of the air bag, the pressure maintaining air bag box only slows down the reduction speed of the water pressure in the water channel in a short time due to the rapid leakage of the water in the external water pipe, when the liquid in the pressure maintaining air bag box cannot be supplemented into the water channel, the water pressure in the water channel is rapidly reduced along with the rupture of the water pipe and reaches the triggering threshold value of the low-pressure switch in a short time, and the main controller records a second time difference t when the high-pressure switch and the low-pressure switch are triggered ₂ The second time difference t ₂ And in a second preset range, the water pipe is judged to be broken, and a water pipe breakage alarm signal is sent. For example, the second predetermined range may be set based on experimental data, such as 3-10 seconds, when t ₂ And when the water pipe is broken for 3-10 seconds, the water pipe is judged to be broken, and a water pipe breakage alarm signal is sent, for example, a water pipe breakage signal lamp is turned on and/or a buzzer alarm is sent.

In some embodiments, when the second solenoid valve of the clean water tank is opened for normal water supplement, the water pressure in the external water pipe is extremely reduced, the continuous trigger state of the high-pressure switch is stopped, at the moment, the liquid in the pressure maintaining air bag box is supplemented into the waterway due to the shrinkage of the air bag, the water flow in the external water pipe is extremely high, the pressure maintaining air bag box can only instantaneously slow down the reduction speed of the water pressure in the waterway, when the liquid in the pressure maintaining air bag box cannot supplement the liquid into the waterway, the water pressure in the waterway reaches the trigger threshold value of the low-pressure switch in an extremely short time, and the main controller records a third time difference t when the high-pressure switch and the low-pressure switch are triggered ₃ The third time difference t ₃ And in a third preset range, normal water supplement is considered, no alarm signal is sent, and a normal water supplement signal can be sent. Wherein the third predetermined range can be set according to experimental data, such as 0-3 seconds, when t ₃ And when the water is supplemented for 0-3 seconds, the water is considered to be normally supplemented, a normal water supplementing signal is sent, for example, a normal water supplementing signal lamp is turned on, and the normal water supplementing signal lamp is turned off after the water is supplemented.

In some embodiments, when the external water pipe causes rapid liquid leakage due to breakage, at this time, the water pipe breakage causes serious water leakage, and the trigger interval to the high-low pressure trigger switch is close to that when the second electromagnetic valve is opened during normal water replenishing, for example, also within a third preset range, the main controller cannot judge whether normal water replenishing or water pipe breakage occurs, and at this time, the control may be performed through the following control logic. The master control box is further configured to: the second electromagnetic valve is closed within a first preset time period, and the first electromagnetic valve is closed within a second preset time period, wherein the second preset time period is at least partially overlapped with the first preset time period; and in a time period overlapping the second preset time period and 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 fraction of the second preset time period being the first preset time period.

As shown in fig. 12, the detection of the presence or absence of a water pipe breakage can be described by a timing chart. When the water level of the clean water tank reaches a detection position of a water-free detection sensor (such as a water-free Hall sensor), a second electromagnetic valve of the clean water tank is opened, which is recorded as 0 second at this time, water in the pipeline is released, the pressure in the pipeline is reduced, a low-pressure switch is triggered, a first electromagnetic valve is opened, which is recorded as 1 second at this time, for example, water in a faucet is replenished into the pipeline, a second electromagnetic valve is closed, which is recorded as 1.5 seconds at this time, after a preset time, the first electromagnetic valve is closed, which is recorded as 3 seconds at this time, namely, after the second electromagnetic valve is closed, water is continuously supplied for 1.5 seconds, the first electromagnetic valve is closed, the high pressure is kept in the pipeline in the time period, namely, the water is filled for a period of time, for example, 2 seconds before water is replenished every time, whether the high-pressure state in the pipeline can be detected, the first electromagnetic valve is closed for 1 second, which is recorded as 4 seconds at this time, the high-pressure in the pipeline cannot be maintained if the pipeline is broken, and therefore, the high-pressure pipeline can be judged in the no-break state, and the water-free condition can be determined. Then the second electromagnetic valve is opened for example at 5 seconds to start normal water replenishing, and the second electromagnetic valve is closed until the clean water tank is full. Therefore, the problem that the water leakage phenomenon is more and more serious due to continuous water supplement under the condition that the water pipe is broken can be avoided.
