Cleaning device for chemical experiment test tube

Abstract

The invention discloses a cleaning device for a chemical experiment test tube, and relates to the technical field of chemical experimental equipment. The cleaning device comprises a power mechanism, an inner cleaning mechanism and an outer cleaning mechanism; the power mechanism comprises a hand-held shell; a driving motor is arranged in the middle of the inside of the hand-held shell; a driving gear is in transmission connection with a drive gear through a transmission gear; the inner cleaning mechanism comprises an upper cleaning shaft fixedly connected with the lower end of a connecting shaft; the lower end of the upper cleaning shaft is connected with a crankshaft; the other end of a butting seat is fixedly connected with a supporting cleaning shaft; the lower end of the crankshaft isconnected with a lower cleaning shaft; the lower end of a rotating plate is fixedly provided with a hemispherical cleaning shell; the outer cleaning mechanism comprises a base, a side barrel and a topbarrel; and the lower end of a positioning rod is fixedly connected with an arc-shaped brush plate which is vertically arranged. The cleaning device has the advantages that a separate supporting clamping structure is not needed, the test tube can be conveniently cleaned, dead spots can be effectively avoided, and the cleaning effect is good.

Description

technical field [0001] The invention relates to the technical field of chemical experiment equipment. Background technique [0002] In chemical experiments, various test tubes need to be used for processing, and the test tubes need to be cleaned. General experiments have a greater impact on the inner wall of the test tube. In particular, high-quality cleaning of the inner wall is required. At the same time, it is necessary to clean the outer wall. Clean up. Among the test tubes, there is a branched test tube with side branch tubes. The general cleaning brush tool cannot efficiently clean the inside and outside of the test tube. Especially when it is necessary to clean the main tube and branch tubes step by step, it is easy to contaminate the cleaned part. Now Among the tools, there is no tool that can achieve efficient cleaning for test tubes with supports; most of the existing cleaning tools need a fixed support and clamping mechanism to clamp the outer wall of the test tu...

Problems solved by technology

Among the test tubes, there is a test tube with branches, which has a side branch tube. The general cleaning brush tool cannot clean the inside and outside of it efficiently, especially when it is necessary to clean the main tube and branch tubes step by step, it is easy to contaminate the cleaned part. Now Among the tools, there is no tool that can achieve efficient cleaning for test tubes with supports; most of the existing cleaning tools need a fixed support and clamping mechanism to clamp the outer wall of the test tube, or need to be fixed by hand, which is inconvenient to use and affects the cleaning effect ;The traditional cleaning method of rotating around the axis is prone to cleaning dead spots at the position corresponding to the axis at the lowest end. First, the bristles at the bottom corresponding to the axis direction rotate weakly, and the relative friction with the surface of the test tube is less, especially the closest to the center. The point where the brushes participate in friction cleaning is the least, and it is easy to form a fixed rotation track pattern, resulting in dead spots caused by cleaning omissions, and the most central bristles have never changed, even if they move up and down in traditional operations, there is no guarantee of corresponding The bristles at the center point are exchanged and covered, that is, the cleaning effect on the corresponding position of the axis cannot be guaranteed, leaving dead spots
