Description

Technical Field

[0001] The utility model relates to the technical field of test teaching material cleaning, in particular to a test teaching material cleaning device. Background Art

[0002] Beaker is the most commonly used reaction container for simple chemical reactions. When there are scales on the outer wall of the beaker, the volume of the solution inside can be estimated. Some beakers also have a small white or roughened area on the outer wall, in which you can write in pencil the name of the contents. When the reactants need to be stirred, they are usually stirred with a glass rod. When the solution needs to be moved to another container, the mouth of the cup can be tilted toward the side with the protruding notch, and the solution can be poured out smoothly. To prevent the solution from flowing down the outside of the cup wall, you can touch the mouth of the cup with a glass rod, and the solution attached to the mouth of the cup can flow down (drainage) smoothly along the glass rod.

[0003] The Chinese patent with patent application number 202020507992.8 proposes a beaker cleaning device for chemical experiments, including a cleaning chamber, an upper cover, a cleaning component that performs a rotational motion and is used to clean the inner wall of the beaker, and an elastic snap-fit ​​component that is arranged at the bottom of the upper cover and is used to install the beaker; the top of the cleaning chamber is an open structure, and the upper cover is detachably covered at the opening at the top of the cleaning chamber; a first drive device that is drive-connected to the cleaning component is installed at the bottom of the cleaning chamber; the elastic snap-fit ​​component is elastically snap-fitted to the outer wall of the beaker, and the elastic snap-fit ​​component is connected to a second drive device installed on the top of the upper cover, and the second drive device drives the elastic snap-fit ​​component to move in the vertical direction in the cleaning chamber to cooperate with the cleaning component. The utility model of the beaker cleaning device for chemical experiments realizes the automated cleaning operation of the beaker, and the entire cleaning operation is convenient, which reduces the labor of personnel while ensuring the safety of the operation.

[0004] However, after the improvement, the above patent still has water in the cleaning chamber for cleaning the beaker. During the cleaning process, the water does not flow, so it needs to be frequently replaced, which is troublesome to clean and is prone to chemical residues. In addition, the clamp cannot be adjusted according to the size of the beaker and is not fixed in place, which easily causes the beaker to move during the cleaning process, affecting the cleaning effect.
