Please refer to FIG. 2, which is a functional block diagram of a preferred embodiment of a liquid detection device developed in this application, which can be applied to liquid level detection and composition monitoring of a liquid storage container 20. The liquid detection device 21 in this case mainly includes a detector 211 and a controller 212. The detector 211 can be attached to the outside of the liquid storage container 20 and can be used to sense the liquid 200 inside the liquid storage container 20. The volume changes. In this example, the detector 211 mainly includes a capacitive sensor 2110, and the capacitive sensor 2110 generates the sensing signal in response to the proximity of the liquid 200 in its vicinity. Of course, the capacitive sensor 2110 can also be implemented by other types of sensors, such as pressure, piezoelectric/inductive sensors, or optical sensors.

As for the controller 212, it is signally connected to the detector 211, which can be controlled to switch between a first state and a second state, so that the controller 212 can increase to a maximum according to the liquid volume in the first state. A first warning signal is issued under a first specific condition. In addition, when the controller 212 is in the second state, a second warning signal is issued according to the liquid volume decreasing to a second specific condition.

For example, the liquid storage container 20 in this case can be a urine storage bag or a drip bag, and the controller 212 can be controlled by a switch 2120 to switch between a first state and a second state, and then be used respectively Monitoring of urine storage bags and drip bags. The capacitive sensor 2110 attached to the liquid storage container 20 can generate a sensing signal in response to the proximity of liquid in its adjacent area. The first specific condition is that the sensing signal is received and reaches a first specific time (for example, 3 Second, in order to avoid malfunction caused by shaking), the controller in the first state at this time determines that the urine is full, and then sends a first warning signal representing that the urine is full. And the second feature The predetermined condition may be that the sensing signal is not received and a second specific time (for example, 3 seconds, to avoid malfunction due to shaking) is reached, and the controller in the second state determines that the drip is about to be used up, and Send out the first warning signal that the drip is about to run out.
