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
Blower fan 10, the air in the external world is blown into bellows 30 by blower fan 10 by air inlet, it can be seen from the air outlet direction of blower fan 10, wind
The wind speed of the bottom of machine 10 is small and wind speed that face air outlet is turned back by the right side wall 31 of bellows 30 is big, causes by under filter 20
The wind speed for being down to workspace 200 is uneven.Typically, filter 20 need to be set in Biohazard Safety Equipment, primarily serve filter bacteria
With the effect of dust granule, the air of workspace is blown into purification.
As shown in Fig. 2 the present embodiment is related to a kind of Biohazard Safety Equipment, including bellows structure area 100 and it is arranged on bellows knot
The workspace 200 of the lower section of structure area 100, bellows structure area 100 include blower fan 10, bellows 30, the wind-guiding dress being arranged in bellows 30
Put；Air ducting includes flat board 40 and arc-shaped guide plate 50；Flat board 40 is horizontally disposed with the air outlet of blower fan 10；Arc-shaped guide plate
50 are set close to one end of the remote air outlet of flat board 40, and its arc opening opens up towards air outlet on arc-shaped guide plate 50
There are multiple ventilating openings.
Specifically, as shown in Fig. 2 in the present embodiment, being divided in a part of wind blown out from air outlet by flat board 40
Stream guiding on the arcwall face of arc-shaped guide plate 50, and after the arcwall face is turned back through flat board 40 and arc-shaped guide plate 50 it
Between gap guide to the bottom of blower fan 10, increase the bottom of blower fan 10 decline wind speed；Another part wind directly blows to face air-out
On the right side wall 31 of the bellows 30 of mouth, and guide and decline after the right side wall 31 is turned back, due to the effect of air ducting, reduce
The decline wind speed of face air outlet, so as to by the wind in bellows 30 via filter 20 uniformly guiding to workspace 200.
In the present embodiment, the length of flat board 40 and the length of arc-shaped guide plate 50 are equal to the width W of bellows 30, so as to
Flat board 40 and arc-shaped guide plate 50 are fixed on the front-rear side walls of bellows 30 by modes such as welding or screws.In order to preferably
Guide distinguished and admirable to as shown in Fig. 2 one end 41 of the remote air outlet of flat board 40 is located on the directions of L along its length of bellows 30
Centre position, the bottom that its other end 42 can be close to the air outlet of blower fan 10 set or set apart from air outlet bottom certain distance
Put, in the present embodiment, the other end 42 of flat board 40 is close to the setting of air outlet bottom.In this example, it is assumed that blower fan 10
Air outlet is L1 apart from the distance of the left side wall 32 of bellows 20, then the width for setting flat board 40 is 0.5L-L1.Accordingly, at this
In embodiment, as shown in Fig. 2 the straight line where the center of circle of arc-shaped guide plate 50 is the edge of one end 41 of flat board 40, ensure logical
The wind energy for crossing the guiding of flat board 40 is enough preferably blown on the arcwall face of arc-shaped guide plate 50.
In order to avoid air ducting guides most of wind and causes to blow to the air quantity on the right side wall 31 of bellows 30 and reduces, such as scheme
Shown in 3, in the present embodiment, the arc length of the arc opening of arc wind waveguide plate 50 is equal to the air-out open height h of blower fan.
Further, for balanced air quantity so that also have air quantity in the bottom of arc wind waveguide plate 50, as shown in figure 3, along arc
The arcuate directions of shape guide plate 50, which are spaced apart, is provided with three rows ventilation circular hole 51；It is of course also possible to offer in other embodiments
Other shapes（For example, elongate holes, elliptical aperture etc.）, arrangement or quantity ventilating opening.In the present embodiment, such as Fig. 3 institutes
The plane outspread drawing of the arc-shaped guide plate 50 shown, its length are equal to the width W of bellows 30, width（That is the arc length of arc opening）
For h, three rows ventilation circular hole 51 is uniformly offered along its width so that adjacent row corresponds to the distance between circular hole 51 and is
0.25h, the distance between adjacent circular holes are 0.15h in that, in each row, wherein all ventilation circular holes 51 are in the same size and diameter is
0.04h.Certainly, the setting value on circular hole 51 of divulging information can also be other numerical value, not be limited herein.
The Biohazard Safety Equipment of the present embodiment, flat board 40 and arc-shaped guide plate 50 are set in bellows 30, will by flat board 40
The wind part shunting guiding that blower fan 10 is blown out reaches to arc-shaped guide plate 50 after being turned back by the arcwall face of arc-shaped guide plate 50
The bottom of blower fan 10 simultaneously and then drops to workspace 200；A part of wind is guided to arc by the ventilating opening of arc-shaped guide plate 50 and led
To the bottom of plate 50, into dropping to workspace 200；A part of wind drops to workspace after the right side wall 31 of bellows 30 is turned back
200 so that the bottom wind speed of blower fan 10 becomes big and the wind speed of face air outlet diminishes, and realizes that decline wind speed is uniform, ensures workspace
Air Uniform Flow in 200, reduce the cross-infection rate between sample.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：
It can still modify to the technical scheme described in foregoing embodiments, or which part technical characteristic is carried out etc.
With replacement；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the utility model technology
The spirit and scope of scheme.
