Background technology
At laboratory operation liquid or semifluid, for example shake, pour into, stir or be added to fluid drips on the surface of solids or in the another kind of liquid time, may produce aerosol.And to the agar plate streak inoculation, with suction pipe inoculating cell blake bottle, carry out centrifugal and when carrying out the animal operation, these laboratory operation all may produce aerosol to infecting liquid.The diameter that can't see for these naked eyes is the small liquid of 5～100 μ m less than 5 microns aerosol and diameter, and laboratory worker can not be recognized their existence usually, and may suck or the other materials of cross pollution work top.
Biohazard Safety Equipment is when having infective experiment material for operation primary culture, bacterium strain and diagnostic sample etc.; be used for protecting operator, laboratory environment and experiment material, make it avoid being exposed to issuable infectious aerosol and spatters in the aforesaid operations process and design.
Its principle be by filter with the harmful substance filtering after; air after will filtering by exhaust system is discharged to outside the laboratory or part turns back to work top; reduce because aerosol exposes laboratory infection and the culture cross pollution that is caused; and the protection environment prevents the pollution of the environment.
The structure of Biohazard Safety Equipment comprises support 20, cabinet 10 as shown in Figure 1, and cabinet 10 tops set out air port 11, and the bottom surface is provided with workbench 12, observation window 13 and air inlet 14, is provided with filter material and exhaust system in cabinet 10 inside.
Traditional Biohazard Safety Equipment top outlet inlet is received outside ventilating system, air inlet and lab space UNICOM, and therefore the gas that pollutes constantly enters the workbench operating space of Biohazard Safety Equipment, causes doublely doing super clean bench; And the conventional operation deck plate has only former and later two edges to design for mesh, causes circulation not smooth.
The utility model content
At above-mentioned defective, the purpose of this utility model provides the multipurpose Biohazard Safety Equipment of a kind of high speed circulation, with can only be in the Biohazard Safety Equipment that solves prior art as Biohazard Safety Equipment, and function singleness, and gas can not the circulating filtration utilization, and not smooth technical problem circulates.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of multipurpose Biohazard Safety Equipment of high speed circulation, comprise support and cabinet, be provided with workbench in the described cabinet, the top is provided with air outlet, it is characterized in that, operating space around workbench in the described cabinet is provided with circulation air path, the operating space of described workbench, and two sides and back all cut off with circulation air path; Described cabinet top is provided with a baffle plate, and described air outlet is blocked; All be provided with filter material between described air outlet and the baffle plate and between bench-top and the air channel; Gas flows in described circulation air path when flowing to the air outlet place, is stopped that by described baffle plate the back flows to the workbench operating space of bottom, gets back to circulation air path by workbench again, and described workbench is the structure in the whole network hole.
According to the described multipurpose Biohazard Safety Equipment of the utility model preferred embodiment, described circulation air path comprises the main air duct between cabinet top and the bench-top, the back air channel at workbench back and the lower air duct of workbench bottom, described lower air duct, main air duct and back air channel UNICOM.
According to the described multipurpose Biohazard Safety Equipment of the utility model preferred embodiment, described workbench the place ahead is provided with observation window, and observation window comprises the glass door that can slide up and down the air inlet sealing of cabinet.
According to the described multipurpose Biohazard Safety Equipment of the utility model preferred embodiment, described deep bead can freely be dismantled.
Owing to adopted above technical characterictic, make the utility model than prior art, have following advantage and good effect:
The utility model adopts circulation air path, and top outlet inlet is blocked, and makes gas continue filtration cycle in cabinet, and anterior air inlet do not have the inflow air-flow substantially, reduces external contamination gas and enters, and can doublely do super clean bench; The utility model can reduce the pollution to filter, improves the service life of filter, and gas circulates in cabinet, and multiple times of filtration has improved the cleanliness factor of workbench operating space; And adopt the worktable panel in the whole network hole, make that circulation is more unimpeded.
Certainly, implement any one specific embodiment of the utility model content, might not realize above whole technique effect simultaneously.

The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model done being described in further detail.
Embodiment one
Please refer to Fig. 2 and Fig. 3, the utility model provides a kind of multiduty Biohazard Safety Equipment, comprises support 20 and cabinet 10, is provided with workbench 12 in the cabinet 10, and the top is provided with air outlet, but air outlet is hidden by baffle plate 15, and baffle plate 15 can freely be dismantled.
Operating spaces around workbench 12 in the cabinet 10 are provided with circulation air path, the operating space of workbench 12, and two sides and back all cut off with circulation air path.
Circulation air path comprises the main air duct 21 between cabinet 10 tops and workbench 12 tops, the back air channel 22 at workbench 12 backs and the lower air duct 23 of workbench 12 bottoms, described lower air duct 23, main air duct 21 and back air channel 22 UNICOMs.
