Abstract

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

A dust-free experimental box

technical field

The invention relates to a dust-free experimental box, in particular to a dust-free and aseptic experimental box for biological experiments.

Background technique

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

The object of the present invention is to provide a cheap and practical dust-free experiment box capable of realizing a dust-free and sterile environment. The technical solution adopted in the present invention is: a dust-free experimental box, including a box body (1), a box door, and an exhaust pipe (6), which is characterized in that it also includes: rubber gloves (5), used for experimenters to carry out Operation; fan (2), used to purge the test box and drive the air circulation in the box; precision filter (3), used to filter the air entering the box; exhaust valve (4), used to control the box Exhaust air to prevent gas from entering the box through the exhaust pipe (6); among them: rubber gloves (5) are connected with the box (1), and the air outlet of the fan (2) is connected with the inlet of the precision filter (3) , the outlet of the precision filter (3) is connected to the box body (1), and the exhaust valve (4) is installed on the pipe of the exhaust pipe. Before the test box works, put the samples and tools required for the experiment in the test box, then open the exhaust valve (4), start the fan (2), and purge the box. Due to the existence of the precision filter (3), , to ensure that the air entering the box is dust-free and sterile. At the same time, due to the forced flow of air, the dust and suspended bacteria in the box are discharged from the exhaust pipe with the air. After a certain period of purging, the inside of the box is finally dust-free. bacteria environment. After the purging is completed, the exhaust valve (4) is closed, and the fan (2) is stopped. At this time, the operator can put his hand into the rubber glove (5) to carry out the experimental operation.

As an improvement of the present invention, the above-mentioned dust-free experiment box is characterized in that the rubber gloves (5) are detachable, so that different rubber gloves can be selected and installed according to the size of the experimenter's hand, which is convenient Different people operate.

As another improvement of the present invention, the dust-free test box described above is characterized in that there are two or more rubber gloves (5), so that the test box can support simultaneous experiments by multiple people.

To sum up, the dust-free experiment box provided by the above scheme is cheap, simple and practical, and can well simulate the environment of a dust-free laboratory, and is especially suitable for popularization and use in the fields of education and scientific research.

Description of drawings

Fig. 1 is a structural schematic diagram of the present invention.

Detailed ways

The invention will be further described below in conjunction with the accompanying drawings and specific implementation examples.

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. Among them: the rubber gloves (5) are connected with the box body (1), the air outlet of the fan (2) is connected with the inlet of the precision filter (3), and the outlet of the precision filter (3) is connected with the box body (1) , the exhaust valve (4) is installed on the pipe of the exhaust pipe.

As a preferred solution, the above-mentioned dust-free experiment box is characterized in that the rubber gloves (5) are detachable, so that rubber gloves of different sizes can be installed according to the size of the hands of the experimenter, which is convenient for different people. operate.

As another preferred solution, the above-mentioned dust-free experimental box is characterized in that there are two or more rubber gloves (5), so that the experimental box can support multiple people to conduct experimental operations together.

Claims (3)
