The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as to restriction of the present utility model.
As shown in figure 1, the bottom surface of plenum chamber 1 is provided with air outlet 2, clean operating room plenum chamber airflow guiding device bag
Multiple deflectors 4 are included, multiple deflectors 4 are perpendicularly fixed on the bottom surface of plenum chamber 1, and multiple deflectors 4 are around the structure of air outlet 2
The passage passed through into the air-flow for plenum chamber 1, each deflector 4 is foldable mechanism.For example, four deflectors can be set
4, form a rectangular channel for supplying stream and passing through around air outlet 2.
Wherein, the underrun screw of deflector 4 and plenum chamber 1 is mutually fixed.
Further, the length of deflector 4 is 200~500mm.
As shown in Fig. 2 foldable mechanism includes the first be hinged successively connecting plate 41, the second connecting plate 42 and the 3rd connection
Plate 43, the first connecting plate 41 are perpendicularly fixed on the bottom surface of plenum chamber 1, are respectively provided with the second connecting plate 42 and the 3rd connecting plate 43
There is sucker 45.Wherein the first connecting plate 41, the second connecting plate 42 and the 3rd connecting plate 43 pass sequentially through jointed shaft 44 and are hinged.Make
Used time, the length of foldable mechanism can be adjusted according to real needs, that is, adjusts the entire length of deflector 4, is led when needing shortening
During the entire length of flowing plate 4, the 3rd connecting plate 43 can be flipped up, the sucker 45 on the 3rd connecting plate 43 is adsorbed second
On the surface of connecting plate 42, likewise, when the entire length of deflector 4 needs shorter, the second connecting plate 42 is flipped up,
The sucker 45 on the second connecting plate 42 is set to adsorb on the surface of the first connecting plate 42, now by the 3rd connecting plate 43 relative second
Connecting plate is turned over downwards.Further, it is respectively provided with the inwall of the first connecting plate 41, the second connecting plate 42 and the 3rd connecting plate 43
There is link 46, fixing device is equipped with link 46.Further, fixing device is rope band 7.
When needing to adjust the passway size for the passage that multiple deflectors 4 are formed, as shown in figure 3, can be in the 3rd connection
Rope band 7 is worn in the link 46 of the connecting plate 42 of plate 43 and second, makes 43 relative second connecting plate 42 of the 3rd connecting plate into passage
After portion rotates to an angle, knot and fasten rope band 7, so that 43 relative second connecting plate 42 of the 3rd connecting plate is fixed on set angle
Degree；The passway size for the gas channel that multiple deflectors 4 are formed can be adjusted by the process, so as to adjust the speed of air-flow
And direction.Likewise, when the 3rd connecting plate 53 outwards turns down and is adsorbed by sucker 45 on the outer surface of the second connecting plate 42
Afterwards, the angle of 42 relative first connecting plate 41 of the second connecting plate is also can adjust, angular adjustment is well connected with rope band 7 through second afterwards
Link 46 on the connecting plate 41 of fishplate bar 42 and first, then rope band 7 is knotted and fixed.
Further, deflector 4 uses acrylic board, and acrylic board has splendid transparency, it is ensured that operating room
Illumination requirement, while acrylic board is very strong to environmental suitability, it will not also be made by being subjected to illumination and wind and weather even if long-time
Performance changes, and ageing resistace is good, and acrylic board more accords with excellent combination property and with nontoxic characteristic in addition
Close operating room demand.It is to be appreciated that when deflector 4 is by the first connecting plate 41, the second connecting plate 42 and the 3rd connecting plate 43
During the fold mechanism of composition, the first connecting plate 41, the second connecting plate 42 and the 3rd connecting plate 43 use acrylic board.
Further, the surface of deflector 4 is pasted with antibacterial plate, so that deflector 4 can be protected during long-term use
Good antibiotic property is held, reduces the cleaning difficulty and maintenance cost of deflector 4.It is to be appreciated that when deflector 4 is by first
During the fold mechanism that connecting plate 41, the second connecting plate 42 and the 3rd connecting plate 43 are formed, the first connecting plate 41, the second connecting plate 42
Antibacterial plate is pasted with the surface of the 3rd connecting plate 43.
Further, mesh plate 3 is connected with air outlet 2, so that stream of bringing about the desired sensation is conveyed downwards by mesh plate 3, makes air-flow
It is gentler.
As shown in figure 1, clean operating room is highly 3 meters, the height of operation table 6 is 0.8 meter.The guiding device of the present invention exists
In use, the clean gas flow in plenum chamber 1 conveys downwards through the mesh plate 3 at air outlet 2 in clean operating room, convey downwards
The passage that clean gas flow is formed through multiple deflectors 41 continues to be delivered to the region of operation table 6 downwards, makes the region of operation table 6
Covered by clean gas flow, it is empty to return to purification by the return air inlet 5 being arranged on the both sides metope of operation table 6 for clean gas flow afterwards
Unit is adjusted, so as to form airflow circulating system.In this process, the length of deflector 4 can be adjusted according to real needs.
The design of deflector of the present utility model, make from plenum chamber come out clean gas flow along the passage that deflector is formed to
Lower conveying, reduce the diffusion and decay of clean gas flow, reach operation table region with making clean gas flow more stable and uniform so that
The air-flow of conveying is more nearly laminar flow, reduces the vortex of operation table regional gas stream, and cause clean gas flow that operation is completely covered
Bed region, has been effectively ensured the air purity of operating room；Deflector 4 is foldable mechanism, when on the one hand make it that user uses
The length of deflector 4 can be adjusted according to stop situation of the equipment such as shadowless lamp and tower crane to air-flow, avoid shadowless lamp, hang
The influence that tower or other equipment convey to air draught, on the other hand, foldable mechanism allow deflector 4 length according to
The altitudes of specific operating room and operation table are adjusted, wide adaptation range, it is ensured that preferably air-flow conveying effect；This
The guiding device of utility model is simple in construction, good appearance, easy for installation.
Embodiment described above is only the preferred embodiment to absolutely prove the utility model and being lifted, the utility model
Protection domain not limited to this.The equivalent substitute or change that those skilled in the art are made on the basis of the utility model
Change, within the scope of protection of the utility model.The scope of protection of the utility model is defined by claims.
