[0002] In order to improve the accuracy of water quality detection results, the water sample needs to be digested first. The role of digestion is to use acidic liquid to destroy the organic matter and reducing substances in the water sample at a certain temperature, so that it becomes a part of the measurable. However, the existing digestion device cannot mix the sample and acid liquid in the digestion tube uniformly, resulting in low digestion efficiency and inaccurate detection results.

[0004] In the above-mentioned patent, the main bevel gear rotates half a circle and engages with the first secondary bevel gear, driving the first secondary bevel gear, the rotating rod and the rotating disc to rotate synchronously. The main bevel gear rotates another half circle and engages with the second secondary bevel gear, driving the second secondary bevel gear, the rotating rod and the rotating disc to rotate in the opposite direction for half a circle. This reciprocating motion allows the rotating disc to reciprocate. The main bevel gear has teeth on only one half, so when it comes into contact with the secondary bevel gear, it will be subjected to a large impact and vibration, which may cause the teeth to deform and break after long-term use, affecting the stability of the engagement and possibly causing the rotating direction to change suddenly, resulting in gear teeth and a decrease in rotation stability.
