Since the slit 53 is used to stably introduce the liquid into the shield 50 without causing the splash, the width of the slit 53 has a certain influence on the prevention of the splash of the liquid and the stable flow of the liquid. If the width of the gap 53 is too small, the liquid entering the protective cover 50 will be slow, so that the infrared sensor 40 cannot timely detect the liquid level inside the tank 10; if the width of the slit 53 is too large, the shield 50 may not be able to prevent the liquid from splashing. Therefore, the width of the slit 53 is preferably in the range of 1 mm to 3 mm. Specifically, the width of the slit 53 may be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, or the like, and in the present embodiment, the width of the slit 53 is 2 mm.
