The utility model is for overcoming at least one defect described in above-mentioned prior art, a kind of Mini-generator for gas of improvement is provided, comprise single ball U-shaped pipe and inner sleeve, described single ball U-shaped pipe is made up of thick straight length and thin straight length, side branch is provided with below the upper port of described thick straight length, a ball bubble is also provided with at the lower end of described side branch, the external diameter of described inner sleeve is less than the straight tube internal diameter of described thick straight length, and described inner sleeve can be placed in described thick straight length, the top being encased in the described inner sleeve in described thick straight length will be arranged on the lower end of described side branch.The ball that the Mini-generator for gas of this improvement uses steeps the locational space increase that inner sleeve is placed, rise and prevent from having owing to reacting violent liquid and go out a mouth of pipe or liquid reagent that participation is reacted and promptly can flow and exchange, long period can keep the concentration of liquid reagent, and be unlikely to phenomenon that reaction speed is slowed down gradually, the Mini-generator for gas of this improvement is simultaneously keeping under the feature prerequisite that miniature instrument volume is little, by changing instrument shape structure, reach instrument and there is multifunctionality, overcome the characteristic of miniature instrument due to instrument small volume, and the utility model can prevent the phenomenons such as the ejection liquid carrying out often occurring in heating liquid reagent experimental implementation process in miniature instrument device, the Mini-generator for gas of this improvement both can serve as the container for reaction, can also possess as test tube, gas bottle, drying tube, the functions such as Drexel bottle, have reasonable in design, cheap for manufacturing cost, volume is little, function is many, safe and reliable, easy to use, the advantages such as Optimal Experimental scheme.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of Mini-generator for gas of improvement is provided, comprise single ball U-shaped pipe and inner sleeve, described single ball U-shaped pipe is made up of thick straight length and thin straight length, side branch is provided with below the upper port of described thick straight length, a ball bubble is also provided with at the lower end of described side branch, the external diameter of described inner sleeve is less than the straight tube internal diameter of described thick straight length, and described inner sleeve can be placed in described thick straight length, the top being encased in the described inner sleeve in described thick straight length will be arranged on the lower end of described side branch.
In order to ensure the versatility of laboratory apparatus, solid and liquid substance also can be contacted with each other with this laboratory apparatus, the bottom of described inner sleeve is provided with aperture, this aperture just can allow liquid flow in inner sleeve, thus allows liquid and the solid be placed in inner sleeve chemical reaction can occur.
In order to effectively increase the reaction compartment of the thick straight length of single ball U-shaped pipe, the diameter range being therefore arranged on described side branch lower end ball bubble is Φ 25 ~ Φ 35 mm.
Compared with prior art, the beneficial effects of the utility model are:
The ball that the Mini-generator for gas of this improvement uses steeps the locational space increase that inner sleeve is placed, rise and prevent from having owing to reacting violent liquid and go out a mouth of pipe or liquid reagent that participation is reacted and promptly can flow and exchange, long period can keep the concentration of liquid reagent, and be unlikely to phenomenon that reaction speed is slowed down gradually, the Mini-generator for gas of this improvement is simultaneously keeping under the feature prerequisite that miniature instrument volume is little, by changing instrument shape structure, reach instrument and there is multifunctionality, overcome the characteristic of miniature instrument due to instrument small volume, and the utility model can prevent the phenomenons such as the ejection liquid carrying out often occurring in heating liquid reagent experimental implementation process in miniature instrument device, the Mini-generator for gas of this improvement both can serve as the container for reaction, can also possess as test tube, gas bottle, drying tube, the functions such as Drexel bottle, have reasonable in design, cheap for manufacturing cost, volume is little, function is many, safe and reliable, easy to use, the advantages such as Optimal Experimental scheme.
