Problems solved by technology
Although the working area of the operation uses the principle of negative pressure, which can better ensure leakage, for some experiments with higher protection levels, special attention needs to be paid to the addition of effective organisms. Since this type of operating work area generally has a large opening, During operation, if there are problems such as wind flow in the work area, such as people passing by, and some experimental operators are negligent during operation and do not strictly follow the operating specifications, the problem of biological leakage in the experiment is still prone to occur. , affecting the security
In addition, the current equipment cavity is not partitioned, it is difficult to clean, the design is unreasonable, and the experimental environment is poor, which brings many troubles to the experimenter

Embodiment Construction
[0028] See Figure 1~4 In the embodiment of the present invention, a biological safety laboratory cabinet for a biological safety laboratory includes a cabinet body 1, a first chamber 2, a second chamber 3, an active chamber 15 and a filter processor, wherein, The cabinet 1 is provided with a first chamber 2 and a second chamber 3 spaced apart. The filter processor and the ventilation fan make the first chamber 2 and the second chamber 3 form a working area. The working area forms negative pressure with respect to the external environment of the experiment cabinet, which is characterized by:
[0029] The first chamber or the second chamber is also provided with the movable chamber 15, and the movable chamber 15 forms a negative pressure with respect to the first chamber or the second chamber; the movable chamber can Move horizontally and vertically in the first chamber or the second chamber, so that the movable chamber can be automatically adjusted according to the position of t...

The invention discloses a bio-safety experiment cabinet used in a bio-safety laboratory and relates to the technical field of bio-safety cabinets. By adopting the bio-safety experiment cabinet, not only is protection implemented through negative pressure of a working zone, but also a moveable chamber of a high safety level is set up, the moveable chamber can be automatically adjusted according toa hand operation position of an experiment operator or the position of an operated test tube, and then the opening in the lower end of the moveable chamber is just aligned to the hand operation position of the experiment operator or the position of the operated test tube, therefore, the moveable chamber can be automatically adjusted even if the operation position of the operator is not very standard, and experiment operation can be implemented in an optimal protection safety position; and an infrared ranging probe is adopted for position detection, so that convenience in detection can be improved while accuracy is ensured, and the cabinet is simple and convenient to control.
Description
Technical field [0001] The invention relates to the technical field of biological safety cabinets, in particular to a biological safety laboratory cabinet used in a biological safety laboratory. Background technique [0002] The biological safety cabinet is a box-type air purification negative pressure safety device that can prevent certain dangerous or unknown biological particles from aerosols from escaping during the experimental operation and processing. It is widely used in scientific research, teaching, clinical testing and production in the fields of microbiology, biomedicine, genetic engineering, biological products, etc. It is the most basic safety protection equipment in the first-level protective barrier in laboratory biosafety. [0003] The current biological safety cabinets in the market generally set the working area to negative pressure and the filter area to positive pressure to prevent leakage of biological substances during the experiment, ensure safe operation, a...
