Problems solved by technology
[0002] At present, many biological experiments and medical experiments need to be carried out in a dust-free and sterile environment. Many scientific research institutes, schools, and hospitals have built dust-free laboratories for this purpose. Expensive dust removal and sterilization equipment, high construction and operation costs
Many small-scale verification experiments cannot be carried out due to the high cost of experiments. This problem is particularly prominent in the biology and medical experiment courses of colleges and technical secondary schools, which is very unfavorable for the education of biology and medicine.

Embodiment Construction
[0008] The invention will be further described below in conjunction with the accompanying drawings and specific implementation examples.
[0009] As shown in the figure, 1 is a dust-free experimental box, including a box body (1), a box door, an observation window, and an exhaust pipe (6), and it is characterized in that it also includes: rubber gloves (5), used for experimental operations, and the end It is tightly connected with the circular mouth of the box. During the experiment, the experimenter puts his hands into the rubber gloves to operate the experimental equipment; the fan (2) is used to supply air to the box (1) for blowing and removing the air in the box Suspended impurities; the precision filter (3) is used to filter the dust and impurities in the air to ensure that the air entering the box is clean and dust-free; the exhaust valve (4) is used to control the air flow in the box. The air valve (4) is also closed to prevent outside air from entering the casing. Am...

The invention discloses a dust-free experimental box which is composed of a box body (1), a box door, an observation window, a draught fan (2), a precise filter (3), rubber gloves (5), an exhaust duct (6) and a vent valve (4). In the work process, a tested object and tools are placed in the box, the box door is closed, then the draught fan (2) is started, the vent valve (4) is opened, the inner portion of the box body is blown, after blowing is completed, the vent valve (4) and the draught fan (2) are closed, and then a tester stretches the hands into the rubber gloves (5) to carry out the test operation. The dust-free experimental box can achieve the function of a dust-free laboratory, and is lower in cost and especially suitable for being used in places of some small dust-free tests.
Description
technical field [0001] The invention relates to a dust-free experimental box, in particular to a dust-free and aseptic experimental box for biological experiments. Background technique [0002] At present, many biological experiments and medical experiments need to be carried out in a dust-free and sterile environment. Many scientific research institutes, schools, and hospitals have built dust-free laboratories for this purpose. Expensive dust removal and sterilization equipment, high construction and operation costs. Many small-scale verification experiments cannot be carried out due to the high cost of experiments. This problem is particularly prominent in the biology and medical experiment courses of colleges and technical secondary schools, which is very unfavorable for the education of biology and medicine. Contents of the invention [0003] The object of the present invention is to provide a cheap and practical dust-free experiment box capable of realizing a dust-fr...
