Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Accompanying drawing in type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model part of the embodiment, rather than whole embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to
The scope of the utility model protection.
As shown in figure 1, it is the front-view schematic diagram of Biohazard Safety Equipment of the prior art, in the workspace 200 of safety cabinet
Top be provided with bellows structure area 100, offer air inlet in the one end in bellows structure area 100, the air inlet set
The air in the external world is blown into bellows structure area 100 by blower fan 10, blower fan 10 by air inlet, and a part of wind passes through air intake filter
Workspace 200 is dropped to after 20 filterings, the air intake filter 20 mainly plays filter bacteria and dust granule, is blown with purification
Enter the air in workspace 200.Biohazard Safety Equipment front window is both provided with inflow entrance, and human users' mouth.In Biohazard Safety Equipment
Standard in, it is necessary to which the inflow wind speed into inflow entrance is more than or equal to 0.5m/s, for protecting operating personnel.According to inflow wind
Speed is equal to the relation of discharge wind speed, and the utility model reaches the purpose that adjustment flows into wind speed by adjusting air draft wind speed.
As shown in Figures 2 and 3, the present embodiment is related to a kind of Biohazard Safety Equipment, including bellows structure area 100 and is arranged on wind
The workspace 200 of the lower section of box structure area 100, bellows structure area 100 include blower fan 10, exhaust-air filter 30, air draft sensor 50,
Air draft governor motion and controller（It is not shown）；Air draft governor motion includes adjustable row aerofoil 40 and for driving adjustable row
The motor 60 of the aperture of aerofoil 40, adjustable row aerofoil 40 are arranged on the top of exhaust-air filter 30；The row of being arranged on of air draft sensor 50
Between wind filter 30 and adjustable row aerofoil 40 and for gathering discharge wind speed；Blower fan 10, motor 60 and air draft sensor 50
It is electrically connected with the controller.
Specifically, as shown in Fig. 2 air draft sensor 50 is used for when opening adjustable row aerofoil 40, detect from bellows knot
The air draft wind speed of discharge in structure area 100, when beginning to use Biohazard Safety Equipment, controller controlled motor 60 is gradually opened adjustable
The aperture of air draft plate 40, while control blower fan 10 to start working, blower fan 10 will be blown into the wind speed one in bellows structure area 100 from the external world
Part enters workspace 200 by air intake filter 20, and a part discharges the external world by exhaust-air filter 30, now air draft sensing
Device 50 detects air draft wind speed, and when air draft wind speed reaches 0.5m/s or more, motor 60 is stopped, and now keeps adjustable row
The aperture of aerofoil 40, Biohazard Safety Equipment is set to be in steady operational status.When there is operating personnel to enter in cabinet, personnel can block stream
Entrance, cause to flow into wind speed reduction, the wind speed that blower fan 10 is blown out（Including declining wind speed and discharge wind speed）It is obstructed, so as to cause to arrange
Wind wind speed reduce, now when air draft sensor 50 detects that air draft wind speed is less than 0.5m/s, controller receive the signal with
Control blower fan 10 increases speed and motor 60 rotates the aperture for increasing adjustable row aerofoil 40, so as to increase air draft wind speed, until
Air draft sensor 50 detects that air draft wind speed reaches 0.5m/s or more, and motor 60 is stopped, and now keeps adjustable air draft
The aperture of plate 40, Biohazard Safety Equipment is set to be in steady operational status.The Biohazard Safety Equipment is realized indirect by detecting air draft wind speed
Detection stream enters the purpose of wind speed so that air draft wind speed is reliably controllable, and in the case where not influenceing to decline wind speed, increases blower fan 1
Rotating speed, the increase of air draft wind speed is realized, and then increase and flow into wind speed, realize the safeguard protection to operating personnel.When air draft sensor
50 detect that discharge wind speed when being zero, shows that blower fan 10 does not work, now in order to avoid the top laying dust of exhaust-air filter 30, resistance
Hinder the air draft of exhaust-air filter 30, influence its performance, controller is receiving the discharge wind speed that air draft sensor 50 detects
During zero signal, controlled motor 60 drives adjustable row aerofoil 40 to close.
