It is to limit the present invention.Term as used herein " and/or " including the arbitrary of one or more related Listed Items
Combination.
With reference to Fig. 1, the decomposing schematic representation of this utility model one embodiment, including base 100, seal closure 200 are shown
With air knife component 300.
The rectangle mount structure that 100 preferably several section bar of base is spliced, its center is provided with a through hole 101, the through hole
For supply by pending product be exposed to that air knife component 300 formed it is distinguished and admirable among, it is preferred that through hole 101 is rectangle
Hole.
Seal closure 200 is tightly connected with base 100, and to form a cavity between, product is placed in the cavity
Row dust removal operation, on the one hand can strengthen distinguished and admirable purging effect, on the other hand can also constrain in distinguished and admirable in seal closure
Portion, it is to avoid dust loss.Specifically, the bottom of seal closure 200 is provided with the installation side 210 of a circle level, and the installation side is connected to
The upper surface of base 100, and pass through screw lock.The top of seal closure 200 is additionally provided with an exhaust outlet 220, and the exhaust outlet can be with
Exhaust duct (not shown) is connected, so as to dust and other impurities are sent to corresponding storage device, it is to avoid cross-contamination occurs.When
So, exhaust outlet 220 can also on demand located at the other positions of seal closure.
Air knife component 300 is located within the cavity formed with base 100 by seal closure 200, side of the gas outlet towards through hole 101
To setting.The air knife component can be formed it is distinguished and admirable product is purged, it is distinguished and admirable except table directly to product just to gas outlet
Outside face is purged, other surfaces (such as side wall etc.) is purged after can also being reflected by the inwall of seal closure,
So as to realize thoroughly removing comprehensively.
With reference to Fig. 2, the decomposing schematic representation of this utility model air knife component and its mounting structure is shown, in this utility model
Air knife component can be rotated with respect thereto, so as to adjust the direction of gas outlet, specifically, as illustrated, including located at base
Hinged seat 110 on 100, hinged seat 110 are provided with arcuate groove 111 and the shaft hole 112 located at the arcuate groove circle centre position, wind
The two ends of knife assembly 300 are provided with hinged ear 310, pass through one turn between hinged ear 310 and the shaft hole 112 of corresponding hinged seat 110
Axle (not shown) connects, and is connected by threaded fastener (not shown), thus, air knife component 300 can between arcuate groove 111
The direction of gas outlet is adjusted to rotate relative to hinged seat around the shaft, regulation then carries out solid by threaded fastener after finishing
Fixed, air knife component can also adopt other conventional rotation connection structures.
Air knife component 300 includes main body 320 and upper lid 330, and the upper surface of main body 320 is provided with air flow channel 321, the air
Runner 321 forms air inlet 322 in main body.Upper lid 330 is fixed by screws in the top of main body 320 and covers air flow channel
321, and upper lid 330 forms a slit for connecting air flow channel with the junction of main body 320, the slit is used as above-mentioned outlet
Mouthful, the air injected by air inlet 322 just can form the air-flow of high speed after slit.
With reference to Fig. 3, use schematic diagram of the present utility model is shown, biopsy cavity marker devices process has been carried out to seal closure in figure,
