Technical Field

[0001] This invention relates to the field of experimental apparatus technology, and in particular to an experimental apparatus for early childhood education. Background Technology

[0002] As living standards improve, people are paying more and more attention to children's education, and many parents are focusing on cultivating their children's interests from the early childhood stage.

[0003] In the early childhood education stage, in order to stimulate children's interest in science, cultivate scientific thinking, and acquire scientific knowledge, more and more educational institutions have introduced early childhood experimental classes, which use experimental teaching to present scientific phenomena in an intuitive and interesting way.

[0004] During experiments for young children, experiments are usually conducted on a laboratory table in transparent experimental cups, such as experiments on the diffusion and mixing of pigments. After each use and before the next experiment, the experimental cups need to be cleaned. The traditional cleaning method requires manually washing the experimental cups at the sink, which is inefficient and the back-and-forth movement of the teaching staff often interrupts the teaching and affects their concentration.

The lever 31 is installed on the first water pipe 7 by a fixing member, and one end of the lever 31 is located on the movement path of the ball head rod 22. In early childhood education experiments, transparent experimental cups (4) are often used for experimental demonstrations; By setting up a cup cleaning mechanism, after use, the experimental cup 4 can be installed in the fixing clamp 32. Based on the operation of the drive box 3, the conveyor chain assembly 21 moves, thereby moving the experimental cup 4 to the cleaning position. The cleaning tube 5 then operates to clean the experimental cup 4. During the movement, the lever 31 can intermittently actuate the ball head lever 22, which, in conjunction with the spring 27, drives the rotating rod 29 to reciprocate, thus improving the rinsing effect.
