Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
Referring to figs. 1 and 2, the air channel structure of the Biohazard Safety Equipment of the utility model is schematically showed, including
Static pressure chamber 1 and working chamber 2, the bottom end of static pressure chamber 1 are connected to the top of working chamber 2, and a side wall of static pressure chamber 1 is equipped with level
The blower 12 of setting；Side wall 11 and the air draft direction of blower 12 against the static pressure chamber of blower 12 are obliquely installed, the folder of the two
Angle is 110 °~130 °, avoids will lead in side-walls generation air flow swirl or ascending air, air flow swirl or ascending air
The down current on 2 top of working chamber is not uniform enough, so that down current can not protect the product in working chamber 2.Because of manpower
Length limitation, experimentation occur to be equipped with diffuser plate 3 between working chamber 2 and static pressure chamber 1 nearby from front window operation port, dissipate
The bottom surface 21 of flowing plate 3 and working chamber is obliquely installed, and the angle of the two is 5 °~10 °, and working chamber is partial in the bottom surface of diffuser plate 3
2 front window side 22, the air-flow that static pressure chamber 1 can be discharged in diffuser plate 3 is oriented to, and makes down current towards working chamber 2
Front window side 22 deviates, and then makes the trouble free service boundary of working chamber 2 closer to the front window operation port of Biohazard Safety Equipment, can keep away
Exempt from laboratory sample by not purified air pollution.Again because down current is deviated towards the front window side 22 of working chamber 2, lower sending down abnormally ascending
The flow path of stream than it is non deflected when it is longer, if the air turbulence being discharged in static pressure chamber 1, uneven, in working chamber 2 under
Sending down abnormally ascending stream can then aggravate this bad phenomenon, and the side wall being obliquely installed in static pressure chamber 1 with the air draft direction of blower 12 can make
The air-flow being discharged in static pressure chamber 1 is more uniform, and then inhibits the non-uniform phenomenon of down current in working chamber 2.Preferably, right
Angle between the side wall 11 of the static pressure chamber of blower 12 and the air draft direction of blower 12 be 120 °.
The C-shaped deflector 13 in cross section is equipped in static pressure chamber 1, the opening of deflector 13 and the air outlet of blower 12 are opposite
The fraction that blower 12 is discharged can be directed to the diffuser plate 3 immediately below blower 12, avoid diffusing by setting, deflector 13
The corner location of plate 3 generates air-flow dead point and causes the air-flow of the air side of diffuser plate 3 uneven.The four of the bottom surface 21 of working chamber
It is equipped with air exhausting grille 21a week, the down current in working chamber 2 is finally pumped into air exhausting grille 21a, and is passed through blower again
In 12, circulation return air.
In addition, being additionally provided with the filter device 4 of plate between static pressure chamber 1 and working chamber 2, filter device 4 is parallel with diffuser plate 3
Setting, filter device 4 can not only filter the gas of the discharge of static pressure chamber 1, additionally it is possible to carry out to the air-flow that static pressure chamber 1 is discharged equal
Stream, further decreases air turbulence.Specifically, filter device 4 is located at the inlet side of diffuser plate 3, the air-flow being discharged in static pressure chamber 1
By filter device 4 filtering and flow, then air-flow is oriented to by diffuser plate 3, so that down current in working chamber 2
It flows to more regular；Conversely, if filter device 4 be set to diffuser plate 3 air side, at diffuser plate 3 be oriented to air-flow again into
Enter filter device 4, will lead to that flowing to for the down current in working chamber 2 is unstable, will cause product by not purified air
Pollution.
In conclusion the air channel structure of the Biohazard Safety Equipment of the utility model, the side wall 11 of static pressure chamber is equipped with blower 12,
1 side wall of static pressure chamber and the air draft direction of blower 12 against blower 12 are obliquely installed, to avoid air-flow static pressure chamber side wall 11
It forms whirlpool and causes the down current of working chamber 2 uneven；Moreover, being equipped with diffuser plate 3 between working chamber 2 and static pressure chamber 1, dissipate
The bottom surface 21 of flowing plate 3 and working chamber is obliquely installed, this structure can make trouble free service boundary closer to the front window of Biohazard Safety Equipment
Operation port prevents product by not purified air pollution.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change
It also should be regarded as the protection scope of the utility model into replacement.
