Detailed Description

Example one

As shown in fig. 1 to 4, a container with a liquid level check device includes: the container comprises a container bottom 11, a container wall 12, a laser source 21 and a scale 31, wherein the laser source 21 is positioned below the outer side of the container bottom 11 and emits laser beams 22 towards the container at an inclined angle, the scale 31 and the position which is positioned above the container and can receive the laser beams 22 are provided, and the part of the container bottom 11, which is just opposite to the laser source 21, is a light-transmitting part 111 made of light-transmitting materials.

Fig. 1 shows the situation where the laser source is off and there is no liquid in the container.

Fig. 2-4 show that when the liquid level 41 in the container is at different heights, the laser beam 22 entering the air from the liquid level is parallel to the liquid level 41 at the same angle, but the refraction occurs at different heights, and finally the laser beam 22 is refracted to different positions on the scale, i.e. corresponding to different scales. Different positions are calculated in advance and correspond to different liquid level heights, and the liquid level heights are marked on the scale, so that the height value of the liquid level 41 can be directly read through the scale.
