Semi-automatic test tube washer

Abstract

The invention discloses a semi-automatic test tube washer. The semi-automatic test tube washer comprises a liquid conveying pipe, a gear transmission system, a brush rod and a water pump; the gear transmission system comprises a bearing and a tray gear which is arranged on the bearing in a sleeving mode and driven by a motor to rotate around the bearing; the brush rod is hollow to form a channel;the lower end of the brush rod is detachably fixed to the tray gear; a plurality of brush bristles are arranged on the periphery of the brush rod; a liquid outlet of the liquid conveying pipe penetrates through the bearing and then is inserted into the channel; and a liquid conveying port of the liquid conveying pipe is connected with the water pump. The semi-automatic test tube washer achieves semi-automatic washing of test tubes, the washing quality of the test tubes is ensured, and the test tubes are not prone to breaking; the water pump is adopted to control washing liquid and pure water to enter the test tubes in succession, low-efficiency complex operation of manually adding liquid in the washing process can be reduced, and energy can be saved; the brush bristles can ensure the effect that stains on the inner walls of the test tubes are effectively removed, and as the brush bristles are spiral and different in length, the resistance for liquid fed into the tops of the test tubesto flow out of the test tubes can be reduced; and the semi-automatic test tube washer can adopt to the test tubes of different types.

Description

technical field [0001] The invention relates to laboratory equipment for cleaning tube glass containers, in particular to a semi-automatic test tube washer for cleaning laboratory test tubes. Background technique [0002] All over the world, laboratories undertake too many innovative missions. There are too many attempts behind the success of every experiment, and no matter what experiment you do, you can't do without the use of test tubes or other tubular containers, including gas wash bottles, volumetric flasks, Erlenmeyer flasks and even beakers. And these containers are not disposable items. In order to save costs, each laboratory will clean and use these containers repeatedly, so cleaning test tubes has become a heavy task for scientific researchers. [0003] Although there has always been a strong demand for instruments that can effectively clean test tubes in the market, many people have carried out some exploratory research and tried to develop some automatic cleani...

And these containers are not disposable items. In order to save costs, each laboratory will repeatedly clean and use these containers, so cleaning test tubes has become a heavy task for scientific researchers.

[0003] Although there has always been a strong demand for instruments that can effectively clean test tubes in the market, many people have carried out some exploratory research and tried to develop some automatic cleaning devices that can clean test tubes conveniently, but there are more or less inconvenient factors, such as cleaning Unclean, easy to cause test tube rupture, cumbersome operation, etc.

At present, most laboratories rely on intensive manpower to clean one by one with test tube brushes, which is inefficient and wastes water resources
