Device for effectively cleaning test tubes with different calibers

Abstract

The invention relates to the technical field of biology, and discloses a device for effectively cleaning test tubes with different calibers. The device comprises a base, wherein the inner bottom wall of the base is rotatably connected with a brush rod, the top of the brush rod is sleeved with a test tube, the outer side of the brush rod is movably connected with bristles, the two sides of the bottom of the brush rod are movably connected with limiting pieces, rubber is fixedly connected to the positions, close to the two sides of the brush rod, of the inner bottom wall of the base, and evenly-distributed contacts are fixedly connected to the bottoms of the rubber. According to the device for effectively cleaning the test tubes with different calibers, through cooperative use of a magnetostrictive material and a telescopic piece, when the calibers inserted into the test tubes are larger, the circuit resistance after the contacts are in contact with a winding coil is smaller, the circuit voltage is larger, and the electrified magnetism of a second electromagnet is larger; and therefore, the effect of driving the magnetostrictive material to move farther is achieved, the purpose of pushing the bristles to move farther outwards is effectively achieved, the cleaning diameter of the brush rod is increased, and the effect of cleaning the test tubes with different calibers is achieved.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a cleaning device for effectively realizing test tubes with different calibers. Background technique [0002] Test tubes, commonly used in biological research and chemical laboratory instruments, are mainly used for reaction containers of a small amount of reagents and some research liquids, and test tubes are usually used at room temperature or when heated. Test tubes can be divided into ordinary test tubes, test tubes with branches, centrifuge There are many kinds of test tubes, etc. The cleaning equipment used for cleaning the used test tubes cannot meet the cleaning requirements for test tubes of different calibers. [0003] After each test tube is used, the test tube needs to be cleaned frequently to ensure that the reaction substances are not affected. However, the existing test tube cleaning equipment has a cumbersome structure and cannot clean test tubes of different calibers...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a cleaning device for effectively realizing test tubes of different calibers, which has the advantages of realizing the cleaning of test tubes of different calibers, and avoiding the shaking of the test tubes during cleaning, so as to achieve a good cleaning effect on the test tubes and solve the problem of The existing test tube cleaning equipment can only clean one size, resulting in most of the test tubes not being cleaned effectively, thus affecting the work efficiency
