Chemistry teaching equipment maintenance device

Abstract

The invention discloses a chemistry teaching equipment maintenance device comprising an injection pipe and liquid absorbing cotton. The injection pipe comprises a pipe wall, a pull rod and a seal block. A liquid storage cavity is formed in the pipe wall. The pull rod is embedded in the liquid storage cavity and is movably connected with the pipe wall. The seal block is arranged at the bottom of the pull rod and is nested in the bottom end of the pull rod. The inner wall of a chemistry teaching vessel is cleaned directly by the chemistry teaching equipment maintenance device, especially cleaning maintenance treatment can be conducted with different cleaning fluids for different substances, washing is not needed in the treatment process, cleaning fluid is washed away only after cleaning is completed, the water using amount is reduced greatly, water resources are saved, meanwhile the chemistry teaching equipment maintenance device can be inserted into the vessel, soaking reaction is fullyconducted for certain substances difficult to treat, the cleaning maintenance effect is improved, and the chemistry teaching equipment maintenance device has wide market prospects and application prospects.

Description

technical field [0001] The invention relates to the technical field of equipment maintenance devices, in particular to a chemistry teaching equipment maintenance device. Background technique [0002] The maintenance device of chemistry teaching equipment refers to the device for effective cleaning and maintenance of utensils such as beakers and shunts involved in chemistry teaching. Experiments are an important means to cultivate students' observation, hands-on, and thinking abilities, and are indispensable for completing teaching activities. Therefore, experiments play an important role in chemistry teaching. Chemical experiments can help students understand and master the chemical knowledge and skills they have learned, stimulate students' interest in learning chemistry, create lively teaching scenarios, inspire students' scientific thinking, improve students' scientific literacy, and cultivate students' scientific attitudes and values are all significant. The cleaning, ...

Problems solved by technology

The cleaning, maintenance and maintenance of the experimental instruments are not in place. The dirt of the instrument not only affects the performance of the instrument, shortens the service life, directly affects the experimental effect, but also affects the success or failure of the experiment. Therefore, cleaning, maintaining and maintaining the experimental instruments is the first priority before the experiment. important link

[0003] However, the analysis found that in the cleaning and maintenance process of the existing chemical teaching equipment maintenance device, the water demand is large, there is a certain waste of water resources, and the cleaning and maintenance effect on high molecular organic matter or impurities hardened in the vessel is poor. There is room for improvement
