The design of the coffee machine is becoming more and more convenient for people to use. Usually, the coffee machine has a water tank for storing water. The coffee machine can realize the water level detection of the water tank. The water level detection function of the coffee machine is realized by installing the water level sensor. Generally speaking, coffee machines require these two kinds of water level detection functions: low water level alarm. High liquid level reminder. Low liquid level reminder is to remind users to add water in time, but also to design a water filling device to avoid damage to the coffee machine due to lack of water and dry burning. The low level indication is the need to install the water level sensor at a set low level. When the water level is below the low liquid level, the sensor does not detect the water and sends a prompt. When the device receives a sensor signal, a power-off prompt or an alarm prompt will be given.
If the coffee machine wants to realize the automatic water filling function and needs to stop adding water when the water reaches a certain water level, the water level sensor can be installed at the set high level. When the liquid level reaches a high level, automatically stop adding water, so that the water does not overflow, the low liquid level, water shortage in advance, automatic water replenishment. Can choose photoelectric water level sensor, small volume, high precision, long service life.
