The application of steam iron in daily life is more and more extensive. Generally, steam irons have a water tank, the principle of which is to release steam by heating for ironing.
With the work of the steam iron, the water in the water tank will become less and less. If the water is not added in time or the work is stopped in time, it will cause damage to the machinery and equipment. Therefore, there needs to be a function that is to promptly remind of lack of liquid, or to protect the power when lack of liquid.
How to realize this function?
A liquid level sensor can only detect the change of liquid level at one point. According to this situation, a photoelectric liquid level sensor can be installed at the bottom to detect low liquid level. When the steam iron is working, the water in the water tank slowly decreases, and when it drops to a low level, the liquid level sensor senses the change in the liquid level, with water output at low level and no water output at high level. After the device receives the sensor signal, it performs power-off protection or reminds.
This function can not only avoid the protection of the steam iron when there is no water, but also avoid the situation that the water tank has no water while the clothes are half ironed when ironing clothes.
Moreover, the steam iron can also perform functions such as controlling the water pump and adding water according to the different sensor signals.
