In one embodiment, referring to fig. 1 to 3, a toilet tank malfunction detection alarm 100 includes: the controller 110, the said controller 110 is used for installing on water tank; a detection component 120, one end of the detection component 120 is electrically connected to the controller 110, and the other end of the detection component 120 is used for extending into the water tank, the detection component 120 is used for detecting water level data in the water tank and sending the water level data to the controller 110, and the controller 110 determines what water leakage condition the water tank is in according to the received water level data; and the alarm 130, wherein the alarm 130 is electrically connected with the controller 110, and when the controller 110 determines that the water tank is in water leakage, the alarm 130 is triggered to work.

The toilet tank fault detection alarm 100 described above operates by mounting the controller 110 to the tank and extending one end of the probe assembly 120 into the tank. The water level data in the water tank is monitored in real time through the detection component 120, so that the controller 110 can accurately judge the water leakage condition according to the acquired water level data; and correspondingly starting the warning indicator 130 and the indicating lamp 140 according to the water leakage condition to remind the user in time, so that the toilet can be maintained as soon as possible, and the water cost burden is reduced. The alarm 100 has a simple structure and is easy to realize; simultaneously the calibration is simple, convenient operation does not need more setting of user or participation, and the operation precision just is difficult for receiving water pressure, temperature, impurity or the influence of polluting.

In practical application, the water leakage can be divided into overflow, large water leakage and small water leakage.

The overflow is caused by the quality problem of the water inlet valve or the improper installation, so that the water level is abnormally increased, and then the water flows out from the overflow pipe at the top, and the water resource waste is caused.

Small water leakage: according to the urban water supply quality standard of China, optimistic estimation is carried out, and the water used by a toilet is assumed to be drinking water with the calcium and magnesium concentration of 180 mg/L. If every toilet is new, sediments and dirt are bred every year, so that the drainage valve at the bottom of the wharf cannot be meshed with the drainage pipe at the bottom of the wharf, and a gap is formed. This is inevitable no matter how well the toilet is designed and functioning.

The occurrence of large water leakage is different from small water leakage, and is often caused by that when the toilet is used each time, the water valve does not fall down and then covers the water discharge pipe, so that continuous large-dose water loss is caused. The next time the user uses the toilet, the correction will not be made. This possibility exists every time each toilet is used.

To facilitate understanding of the working principle of the alarm 100, the conditions of large water leakage and small water leakage are taken as examples for explanation. If the full water level is continuously exceeded for 3 minutes, the water inlet valve is judged to be closed. If the water tank does not reach the full water state within 10 minutes, the alarm is given, and the water tank is judged to have large water leakage or no water inflow. If the water tank is changed from full water state to not full water state and the water tank is not in short water state within 20 seconds, the abnormal state of small water leakage is considered. The alarm 130 may be a buzzer.

Further, an indicator lamp 140 is also included. The indicator lamp 140 is electrically connected to the controller 110, and when the controller 110 determines that the water tank is leaking, the indicator lamp 140 is turned on. Therefore, the present embodiment employs both the alarm 130 and the indicator 140. When the controller 110 determines that the water tank is leaking, the indicator lamp 140 is turned on; meanwhile, the alarm 130 gives an alarm when working, so that double reminding of light and sound is realized, and a user can find out a water tank fault in time and maintain the water tank.

Specifically, the indicator light 140 is an LED.

In one embodiment, the probing assembly 120 includes a hub 121 and a probing wire 122. The number of the detection wires 122 is two or three, one end of each of the two or three detection wires 122 is electrically connected to the controller 110, the other end of each of the two or three detection wires 122 is used for extending into the water tank, and all the detection wires 122 are fixed together through the hub 121. In this way, all the detection wires 122 are fixed together by the hub 121, and the situation that all the detection wires are too scattered in the water tank to be managed is avoided. Meanwhile, the influence of loose detection wires 122 on the detection result is avoided.

Specifically, the hub 121 may be a plastic member, which is sleeved on all the detecting wires 122 respectively to be fixed together.

It should be noted that the detection wires 122 are positive and negative wires of a capacitor, and have a sensing function.

In one embodiment, referring to fig. 3, the controller 110 includes a single chip and a circuit board 111 having at least an oscillating circuit built therein. The detection component 120 and the single chip microcomputer are electrically connected with the circuit board 111. The oscillation circuit in the circuit board 111 is used for correspondingly changing oscillation frequency according to the water level data, and the single chip microcomputer is used for calculating the water level height according to the change of the oscillation frequency and judging the water leakage condition. Therefore, when the water leakage condition is determined, the circuit board 111 acquires the water level data in the detection assembly 120, and changes the oscillation frequency according to the water level data. When the single chip microcomputer detects the frequency change in the oscillating circuit, the water capacity can be calculated, and then the height of water in the water outlet tank is calculated.

It should be noted that the Single-Chip Microcomputer (Single-Chip Microcomputer) is an integrated circuit Chip, and is a small and perfect Microcomputer system formed by integrating functions (possibly including circuits such as a display driving circuit, a pulse width modulation circuit, an analog multiplexer, an a/D converter, etc.) of a central processing unit CPU, a random access memory RAM, a read only memory ROM, various I/O ports, an interrupt system, a timer/counter, etc. with data processing capability onto a silicon Chip by using a very large scale integrated circuit technology.
