When the anti-splash plate 8 moves to the cup mouth of the stirring cup 3, the anti-splash plate 8 blocks the cup mouth of the stirring cup 3 through the moving part to prevent the juice from splashing. At the same time, the position of the stirring cup 3 can be pressed down and fixed, thereby improving the stability of the stirring cup 3 and reducing the noise generated during the stirring process. The anti-splash plate 8 is moved downward to the cup mouth of the stirring cup 3, and the anti-splash plate 8 is fixed by the fixing sleeve 9. The splash plate 8 is fixed at this position to cover the mouth of the mixing cup 3, and then the motor 2 is started to rotate, so that the motor 2 drives the crushing blades on the surface of the stirring rod 1 to crush the vegetable samples in the mixing cup 3 until the vegetable samples are processed. The processed samples in the mixing cup 3 are taken out, and then the detergent is added to the mixing cup 3, and the above stirring action is repeated to clean the residues of the vegetable samples on the surfaces of the mixing cup 3 and the stirring rod 1.

After the trigger block 18 contacts the bottom of the stirring cup 3, it can drive the trigger block 18 to overcome the elastic force of the support spring 19 and drive the electric contact 20 to contact the conductive point 17.

[0034] Furthermore, the positions of the electrical contacts 20 and the conductive points 17 correspond to each other, and the electrical contacts 20 and the conductive points 17 are made of copper alloy.

[0037] In addition, when the stirring rod 1 moves downward to the inside of the stirring cup 3, the anti-splash plate 8 will also move to the cup mouth of the stirring cup 3. At this time, the anti-splash plate 8 overcomes the elastic force of the traction spring 15 to block the cup mouth of the stirring cup 3 to prevent juice from splashing. At the same time, the elastic force of the traction spring 15 can press the position of the stirring cup 3 downward to improve the stability of the stirring cup 3 and reduce the noise generated during the stirring process. The anti-splash plate 8 is fixed at this position by the fixing sleeve 9 to cover the cup mouth of the stirring cup 3, and then the motor 2 is started to rotate, so that the motor 2 drives the crushing blade on the surface of the stirring rod 1 The vegetable samples in the mixing cup 3 are crushed until the processing of the vegetable samples is completed. The processed samples in the mixing cup 3 are taken out, and then a detergent is added to the mixing cup 3, and the above-mentioned stirring action is repeated to clean the residues of the vegetable samples on the surfaces of the mixing cup 3 and the stirring rod 1. This method can facilitate the processing of the vegetable samples, and the anti-splash plate 8 can be adjusted in height to adapt to mixing cups 3 of different heights. It can not only better prevent water splashing during the crushing process of the vegetables, but also isolate the odor generated by the vegetables during the crushing process to a certain extent.

[0038] It is worth mentioning that, considering that some vegetable samples far away from the crushing blades during the crushing process are easy to splash freely on the upper inner wall of the mixing cup 3, a stopper 22 and a slide groove 23 are provided for use together. During the rotation of the mixing rod 1, the ball 24 on the stopper 22 can be driven to reciprocate along the direction of the slide groove 23, driving the extrusion plate 10 to push downward the vegetable samples that are not evenly crushed on the upper layer of the inner wall of the mixing cup 3. In this way, the vegetable samples that are not evenly crushed and splashed on the upper layer of the inner wall of the mixing cup 3 can be pushed downward to contact the blades on the mixing rod 1, so that the whole can be crushed more evenly.
