Description

Technical Field

[0001] The utility model belongs to the technical field of chemical experimental equipment, in particular to a beaker cleaning device for a laboratory. Background Art

[0002] A beaker is a common laboratory glassware, usually made of glass, plastic or heat-resistant glass. Most beakers are cylindrical with a notch on one side of the top for easy pouring of liquids. It is mainly used for laboratory chemical experiments such as heating, dissolving, mixing, boiling, melting, evaporation and concentration. After the laboratory experiment is completed, the beaker is usually cleaned with a cleaning device. In real life, when cleaning a beaker with a cleaning device, since most cleaning devices are fixed in shape and size, it is not convenient to adjust them, so that they can only clean beakers of fixed calibers, which limits the scope of use of the cleaning device and reduces its practicality.

[0003] A Chinese patent document (application publication number CN220387398U) discloses a laboratory beaker cleaning device, which includes a cleaning box, a solution box, a beaker fixing frame, a cleaning component, a hydraulic telescopic rod and an ultrasonic generator. The solution box is arranged on the top of the cleaning box, the cleaning component is arranged on the upper end of the cleaning box, the hydraulic telescopic rod is symmetrically arranged on the upper ends of both sides of the cleaning box, and a bracket is provided on the output shaft of the hydraulic telescopic rod.

[0004] It can be seen that the patent document cited above also has the same problem. Although it has a good cleaning effect and can clean laboratory beakers in batches, the cleaning brush in the cleaning device has a fixed shape and size and is not convenient to adjust, so that it can only clean beakers with a fixed caliber size. This limits the scope of use of the cleaning device, thereby reducing its practicality. Utility Model Content

[0032] How it works

[0033] Turn on the electric push rod switch, the electric push rod 3 drives the horizontal plate 4 to move up, then fix the beaker on the placement plate 15, and inject the cleaning liquid into the beaker. Secondly, according to the caliber of the beaker, open the fixing assembly, move the second cleaning strip 10 outward to the appropriate length, and then lock the fixing assembly. In this way, it is convenient to adjust the overall shape and size of the cleaning strip so that it can clean beakers of different calibers, thereby increasing the use range of the cleaning device and improving its practicality. Then turn off the electric push rod switch and turn on the motor switch in turn. The motor 5 drives the connecting sleeve 7 to rotate through the rotating shaft 6, and then drives the first cleaning strip 9 and the second cleaning strip 10 to rotate through the connecting plate 8. The electric push rod 3 is closed to drive the horizontal plate 4 to move downward and reset, so that the cleaning strip moves downward while rotating, and then the inner wall of the beaker is cleaned. When the cleaning strip needs to be replaced, the screw cover 12 is rotated to separate it from the connecting sleeve 7, and then the elastic block 11 is pressed inward, and the horizontal plate is moved downward at the same time until the connecting sleeve 7 is separated from the rotating shaft 6. This facilitates the disassembly and replacement of the cleaning strip, thereby ensuring the cleaning effect of the cleaning strip.
