Pick-up unit 53 can comprise one or more in output air pump 51, sample air output duct 52, pick-up unit conduit 54 and sample air circulation conduit 55.

If wish to make the sample air of self-test device 53 to be circulated back in container 10, any suitable sample air circulation conduit 55 from the output terminal of pick-up unit 53 to the input end of input air pump 49 can be set so.If there is the material from any danger of goods 26 in sample air, making so sample air be circulated back to may be favourable in container 10.On the other hand, if do not wish to make sample air to be circulated back in container 10, can remove sample air circulation conduit 55 so, and near fresh surrounding air input air pump 49 can be pumped in air input tubular frame members 21a.

If sample air does not circulate, the sample air output of pick-up unit 53 or output air pump 51 can be expelled back in atmosphere so, preferably, by one or more filtrators, this filtrator is removed may be present in any hazardous gas, steam or the particulate in sample air.

Form, can remove input air pump 49 and air input pipe 50 as an alternative, in this case, can only by output air pump 51, provide the sample air stream through container 10.In this case, if wish the sample air circulation, sample air circulation conduit 55 can be directly connected to so to the air input outside port 28 of air input tubular frame members 21a.

As another kind of alternative form, can remove output air pump 51 and sample air output duct 52 thereof, in this case, can only by input air pump 49, provide the sample air stream through container 10, and the pick-up unit conduit 54 for detection of device 53 can be directly connected in to the sample air output outside port 28 of sample air output tubular framing component 21b.

As another kind of alternative form, the output air pump 51 of Fig. 6 and Fig. 7 and the position of pick-up unit 53 can exchange, and make pick-up unit 53 be connected in sample air output outside port 28 by conduit 52, and output air pump 51 are connected in conduit 54,55.This exchange is in the situation that may expect for example, wherein: may have the unloaded particulate that disapproves material in sample air, and the structure of output air pump 51 makes unloaded particulate may clash into and be attached to the rotating part of output air pump 51, thereby undesirably unloaded particulate is removed from sample air.This exchange is in the situation that also may expect for example, wherein: any unloaded particulate that disapproves material be taken up in sample air is small (for example, when unloaded particulate is the microorganism be taken up), and the structure of output air pump 51 makes the meeting when they are output the rotating part collision of air pump 51 of small unloaded particulate destroyed.

Therefore, when pick-up unit 53 receives sample air from sample air output outside port 28, pick-up unit can directly receive sample air from sample air output outside port 28, perhaps indirectly from sample air output outside port 28, receive sample air (for example, can be connected in from its input end the output terminal reception sample air of the air pump 51 of sample air output outside port 28).

Similarly, when output air pump 51 receives sample air from sample air output outside port 28, output air pump 51 can directly receive sample air from sample air output outside port 28, perhaps indirectly from sample air output outside port 28, receive sample air (for example, can be connected in from its input end the output terminal reception sample air of the pick-up unit 53 of sample air output outside port 28).

Utilize tubular frame members 21a, a 21b to be inquired about

Referring now to Fig. 7, utilize tubular frame members 21a, a 21b to carry out the inquiry of container 10 description.Any tubular frame members 21a, 21b self can be used to container 10 is inquired about.

Example, suppose and will only with tubular frame members 21b, container 10 be inquired about.Can see, any suitable separation scraper 56 can be arranged on any suitable position in the air chamber 41 of tubular frame members 21b in any suitable manner, tubular frame members 21b is separated into to air input tubular frame members 60 and sample air output tubular framing component 61.Separation scraper 56 can have any suitable size, shape and physique, and can form gas-tight seal with the inside surface of tubular frame members 21b.

Only utilize a benefit of carrying out the inquiry of container 10 in tubular frame members 21a, 21b to be, carry out the inquiry of container 10 compares due to tubular frame members 21a, 21b with using two total lengths, therefore reduced the axia flow length of its tubular frame members 60,61, the total axial pressure drop along the length of used tubular frame members 21a, 21b can minimize.

In addition, while with the tubular frame members 21a, the 21b that use two total lengths, carrying out the inquiry of container 10, compare, for any given air pressure that inputs or outputs, the resistance to flow provided due to shorter tubular frame members 60,61 is lower, so may desirably increase through the input air of tubular frame members 60,61 or the flowing velocity of sample air, thereby undesirably shorten required time of inside 66 of rough complete querying container 10.

Although separation scraper 56 is depicted as, tubular frame members 21b is divided into to isometric tubular frame members 60,61, separation scraper can be arranged on the position that makes tubular frame members 60,61 not isometric in tubular frame members 21b.

As shown in Figure 7, air input tubular frame members 61 has an air input outside port 28 arranged placed in the middle and four air input internal ports 47.Sample air output tubular framing component 61 has four sample air output internal ports 47 and a sample air output outside port 28 arranged placed in the middle.

Form as an alternative, each outside port 28 can not be to be arranged between two parties in its corresponding tubular frame members 60,61, and can have the outside port 28 more than for one or two in tubular frame members 60,61.As another kind of alternative form, one or two in tubular frame members 60,61 can have still less or more internal port 47, described internal port 47 can along they respective tubular framing component 60,61 length each other equidistantly or equidistantly not spaced apart.Although only show a kind of outside port 28 and internal port 47 of form in Fig. 7, outside port 28 and internal port 47 can comprise any embodiment of outside port 28 described herein and internal port 47.

Any suitable input air pump 49 all can be connected to by any suitable input pipe 50 the input outside port 28 of input tubular frame members 60, at its input outside port 28 places, to provide positive input air pressure.Any suitable output air pump 51 all can be connected to by any suitable output duct 52 the output outside port 28 of output tubular framing component 61, at its sample air output outside port 28 places, to provide negative output pressure.Any suitable pick-up unit 53 for the sample air from container 10 all can be connected in by any suitable sampling catheter 54 output terminal of output air pump 51.Air-flow in container 10 is meaned by air-flow pattern 58.

If wish to make the sample air of self-test device 53 to be circulated back in container 10, any suitable circulation conduit 55 from the output terminal of pick-up unit 53 to the input end of input air pump 49 can be set so.If there is the material from any danger of goods 26 in sample air, making so sample air be circulated back to may be favourable in container.On the other hand, if do not wish to make sample air to be circulated back in container 10, can remove circulation conduit 55 so, and near fresh surrounding air input air pump 49 can be pumped in input tubular frame members 61.

If sample air does not circulate, pick-up unit 53 or output air pump 51 can be expelled back into sample air in atmosphere so, and preferably by one or more filtrators, described filtrator is removed may be present in any hazardous gas, steam or the particulate in sample air.

Form, can remove input air pump 49 and input pipe 50 as an alternative, in this case, can only by output air pump 51, provide the sample air stream through container 10.In this case, if wish the sample air circulation, circulation conduit 55 can be directly connected to so to the input outside port 28 of input tubular frame members 60.

As another kind of alternative form, can remove output air pump 51 and output duct 52 thereof, in this case, can only by input air pump 49, provide the sample air stream through container 10, and the sampling catheter 54 for detection of device 53 can be directly connected in to the outside port 28 of output tubular framing component 61.

The shape of the exhaust openings 68 of air input internal port 47 and air input nozzle 48

To discuss now the shape of the exhaust openings 68 in the air input internal port 47 that there is no nozzle 48 and the shape of the exhaust openings 68 in air input nozzle 48.Exemplarily, by below the shape of the exhaust openings 68 in the air input internal port 47 that there is no nozzle 48 being discussed, should be appreciated that identical discussion can be applicable to the shape of the exhaust openings 68 in air input nozzle 48 equally.

The exhaust openings 68 of air input internal port 47 can have any suitable size and dimension.For example, have been found that what may expect is that the input air jet is transferred to the inside 66 of container 10 from exhaust openings 68, make the input air jet advance to the longest as far as possible distance in inner 66.This may expect, because the quantity of the air input internal port 47 that this inside 66 that can make to inquire about fully any given container 10 may be required minimizes.In addition, this can also increase the area that the inner 66 interior input air jets that can be transmitted by any given air input internal port 47 fully stir, thus query set vanning 10 better.

The quality of usually, the sample air of the inside 66 from container 10 being inquired about and speed will be as the functions of the thorough degree of input air jet covering internal 66 and are increased; Wherein, when the thorough degree of input air jet covering internal 66 increases, the quality of inquiry and speed increase.This be because, if the input air jet is any part of covering internal 66 up hill and dale not, sample air from inside 66 can all possibilities of picking up any gas or any unloaded particulate that disapprove in material from container 10 will reduce so, and vice versa.

The quality of in addition, the sample air from inner 66 being inquired about and speed will increase at the function of the thorough degree of inner 66 interior agitation air as the input air jet.This stirring may be favourable, because the outside surface that the inside surface that this stirring makes the input air jet to expose with container 13 and goods 26 expose interacts, and make the input air jet to remove and to take up at least some from them may to be present in any corpuscle that disapproves on them.Therefore, the quality of inquiry and speed can increase and increase along with the thorough degree of input air jet in inner 66 interior agitation air, and vice versa.

May think that from the input air jet of the turbulence form of air input internal port 47 transmission with circular exhaust openings 68 will be best in this respect.Yet, have been found that in most cases, with the input air jet of the turbulence form of being transmitted by circular exhaust openings 68, compare, the input air jet of the turbulence form of being carried by rectangle exhaust openings 69 can advance in the inside 66 of container 10 more, and stir more fully the air in inner 66.

This be because, as is known, from the sink middle linear velocity V of (submerged) turbulent air jet of the circular cross section of circular exhaust openings 68 _c1can by following equation, come given approx:

${\mathrm{<figure-callout\; id="1"\; label="V\; c"\; filenames="HSA00000075987200071.png"\; state="\{\{state\}\}">V</figure-callout>}}_c=\frac{{0.96Q}_a}{0.071\left(\frac{X}{R}\right)+.29},$ Wherein $\frac{X}{R}>9.4$

In superincumbent equation, Q _athat R is the radius of exhaust openings 68, and X is the distance apart from exhaust openings 68 for the average external volume air mass flow of the per unit area of the exhaust openings 68 of air input internal port 47.

Similarly, be well known that the middle linear velocity V from the rectangular cross section sinking turbulent air jet of rectangle exhaust openings 68 _c1can by following equation, come given approx:

${\mathrm{<figure-callout\; id="1"\; label="V\; c"\; filenames="HSA00000075987200071.png"\; state="\{\{state\}\}">V</figure-callout>}}_c=\frac{{1.2Q}_a}{\sqrt{0.11\left(\frac{X}{B}\right)+0.41}},$ Wherein $\frac{X}{B}>9.4$

In superincumbent equation, B equals half of height of rectangle exhaust openings 68.The ratio of width to height (that is, the ratio of its width and its height) of supposing rectangle exhaust openings 68 is at least 3: 1, makes the end effect of rectangle exhaust openings 68 relatively can ignore.

Referring now to Fig. 8, curve 70,71 shows respectively for the circle with same cross-sectional area and rectangle exhaust openings 68, the phase center line speed (V of the circle of sinking and rectangular cross section turbulent air jet _c1) with the funtcional relationship of nondimensional distance X/R or X/B, wherein rectangle exhaust openings 68 has the ratio of width to height of 10: 1.

Although Fig. 8 shows the circular cross section air-spray, than rectangular cross section air-spray, keep the time of its initial velocity longer, the speed of circular cross section air-spray is along with the distance of distance exhaust openings 68 more promptly reduces than the speed of rectangular cross section air-spray.Therefore, the rectangular cross section air-spray can provide than circular cross section air-spray from the advance advantage of longer total distance of exhaust openings 68.This is that the surrounding air viscous ground with three-dimensional mode and stagnation interacts because of the circular cross section air-spray, thereby with the interactional rectangular cross section air-spray in surrounding air viscous ground of stagnation, compares with two-dimensional approach with main, and it is faster that speed is fallen.

Have been found that, if air input internal port 47 has near and the roof 13 that at least is in substantially parallel relationship to container 10 is discharged the rectangular cross section air-sprays to the rectangle exhaust openings 68 in inner 66, this benefit of rectangular cross section air-spray can strengthen (that is, air-spray can be even farther than the inside 66 that advances to container 10 in other situation) so.Preferably, in order to obtain significantly the benefit of this enhancing, the top of rectangle exhaust openings 68 can be positioned at roof 13 with container 10 at a distance of a vertical distance, vertically distance is not more than 10 times of height of about rectangle exhaust openings 68, and exhaust openings can have the ratio of width to height that is at least 3: 1.

In theory, can obtain the benefit of this enhancing, because the viscous loss near the top side of the air-spray roof 13 that is positioned at container 10 can reduce, this be because the amount of the top side of air-spray and the dacker between roof 13 can be less than air-spray be submerged in unlimited airborne situation (that is, if the distance of air-spray and roof 13 than the height of rectangle exhaust openings 68 approximately 10 times also far).

Further find, if the vertical distance of rectangle exhaust openings 68 and the roof 13 of container 10 is not more than 10 times of height of about rectangle exhaust openings 68, can obtain other benefit so, that is: then the rectangle air-spray may be able to advantageously be removed from the inside surface of roof 13, and takes up any particulate that disapproves material that at least a portion may self be attached to the inside surface of roof 13.This can bring the quicker and sensitiveer inquiry to container 10.

Although should be appreciated that above-mentioned discussion is that circle and rectangular cross section air-flow about turbulence form carries out, same or analogous discussion also can be made for circle and the rectangular cross section air-flow of the laminar flow form from air input internal port 47.

In addition, term " rectangle " is to use in a broad sense for the shape of exhaust openings 68 and the shape of cross section of air-spray, because their shape needs not be strict rectangle.Therefore, term " rectangle " is defined as comprising any geometric configuration or non-geometric configuration, as long as this shape comprehensive average the ratio of width to height on its width is at least 3: 1.For example, though the top surface of exhaust openings 68 and basal surface may be slightly arc, wriggle or zigzag, but not straight, exhaust openings 68 can be still " rectangle " under above-mentioned definition.

Make roof 13 vibrations of container 10

If the material that disapproves that container 10 contains solid or liquid form, when these disapprove material and are stored or transport in container 10, this particulate self that disapproves material may be attached to the inside surface of the roof 13 of container 10 so.

Therefore, before the inquiry of carrying out container 10 or in query script, make roof 13 vibration so that these disapproving of adhering to corpuscle unclamps or discharges from the inside surface of roof 13 may be useful.This then can allow input air jet from air input internal port 47 or air input nozzle 48 take up any that unclamp or discharge disapprove corpuscle; Thereby make these disapprove the part that corpuscle becomes the sample air that can receive from container 10 afterwards, for by any suitable pick-up unit 53, being collected, observe, identify, check, test or analyze.

As additional benefit, when roof 13 vibration, it can launch sound wave downwards in the inside 66 of container 10, then in inner 66, sound wave can unclamp or discharge any corpuscle that disapproves of inside surface of bottom 12, wall 14-16 or the door 17 of at least some outside surfaces that self may be attached to goods 26 or container 10.Then this can allow input air jet from air input internal port 47 or air input nozzle 48 take up any these unclamp or discharge disapprove corpuscle; Thereby make these disapprove the part that corpuscle becomes the sample air that can remove from container 10 afterwards, for by any suitable pick-up unit 53, being collected, observe, identify, check, test or analyze.

Can use one or more any suitable vibrating devices 75 that roof 13 is vibrated in any suitable manner; Described vibrating device 75 can be positioned at any suitable relevant position on roof 13, and can permanently or removedly be installed in any suitable manner roof 13.Vibrating device 75 can comprise any suitable electric, mechanical, the pneumatic or hydraulic vibrator that for example has any suitable size, shape, power source and structure.

For vibrating device 75 being made to the fully required minimum power of vibration of roof 13, make roof 13 under its fundamental resonance frequency or may be favourable with its harmonic vibration.Yet, because the length of typical container 10 is far longer than its width, and because two sidewall 14, the under(-)chassis member 19 of two sidepieces and side frame members 21a, the 21b at two tops have given significant axial stiffness to container 10, so preferably vibrating device 75 inspires its resonance or resonance that points to side direction in roof 13.In this case, the side frame members 21a at two tops, 21b can be used as microscler fixed pivot axi, and roof 13 can be used as in fact crossing over the side frame members 21a at two tops, elastic beam or the plate in the gap between 21b.For roof 13, fundamental resonance frequency can be at about 10Hz in the scope of about 100Hz, and this scope is also for inspiring the useful frequency range of its resonance or resonance in the inside 66 at container 10.

Vibrating device 75 is positioned at or vertical geometric midline 73 of at least close roof 13 may be generally preferred, the middle place of this center line 73 between two sidewalls 14 of container 10.Fig. 9 shows when vibrating device 75 applies cyclic force along center line 73, and roof 13 is for the characteristic range of the vertical motion of its fundamental resonance and its front third harmonic (N=2,3,4).

Vibrating device 75 can apply vertical power of cycle to center line 73, with the fundamental resonance that excites roof 13 with and odd harmonic (N=3,5,7 ...).This cycle vertical force can be applied to roof 13 by any suitable vibrating device 75.For example, this vibrating device 75 can comprise: the electromagnet that is installed on roof 13; Vertically be installed on the reciprocating motion type line motor of roof 13; Perhaps vertically be installed on hydraulic pressure or the electric linear-motion actuator of roof 13.

Yet, the even-order harmonic of the fundamental resonance of roof 13 (N=2 wherein, 4,6 ...) the cycle vertical force that can not apply along center line 73 in response to vibrating device 75 well, because in theory, 73 pairs of even-order harmonics of center line are static.Yet, have been found that roof 13 applied to the even-order harmonic that can cause well the fundamental resonance of roof 13 with respect to the vibrating device 75 of the periodicity rolling of its center line 73.

Periodicity with respect to its center line 73 rolling of roof 13 is following motions, wherein: the part that is positioned near the sidepiece of its center line 73 of roof 13 also relative to each other periodically moves up and down with respect to center line 73,, when the part of the sidepiece that is positioned at center line 73 1 sides of roof 13 moves upward by vibrating device, the appropriate section of the sidepiece that is positioned at center line 73 opposite sides of roof 13 moves downward by vibrating device so; Vice versa, and roof 13 does not significantly move along the part of center line 73.

In addition, the harmonic wave of knowing very much even has experienced along the maximum of the slope of any point of resonance profile and has changed, as seen in Fig. 9.

Any suitable vibrating device 75 can produce the periodicity rolling of roof 13 about its center line 73.For example, as shown in figure 10, vibrating device 75 can comprise: motor 76, and it has the eccentric rotary weight 77 that is installed on its output shaft 78; And any suitable installation frame 79 of strengthening feature that has, the roof 13 that it can contribute to any power that eccentric rotary weight 77 is produced gradually or moment to be delivered to faithfully container 10.Installation frame 79 can have any suitable size, shape and structure, and can comprise rectangular substrate 80 for example, for a pair of stiffening rib 81, optional footing 82 and a pair of motor bracket 83 of the end of substrate 80, described a pair of motor bracket 83 is for attaching to motor substrate 80 and end 81.The all parts of motor and framework 79 can tighten together in any suitable manner, for example, by welding, use bonding agent or securing member.Should be appreciated that can be suitable with any other vibrating device 75 make roof 13 there is the periodicity rolling about its center line 73.

In order to use vibrating device 75, can in any suitable position, it permanently or removedly be installed on to the roof 13 of container 10 by any suitable mode, for example, by using electromagnet, welding, bonding agent or securing member.For example, when framework 79 is installed on to roof 13, the output shaft 78 of motor 76 can be at least substantially vertically directed with respect to the plane of roof 13, and the longitudinal midline of substrate 80 can be arranged at least substantially be positioned at center line 73 tops of roof 13 and at least substantially parallel with center line 73.

When the output shaft 78 of motor 76 rotates, by the eccentric weight 77 of rotating, produced sinusoidal periodicity rolling.This shakes power and then by framework 79, is passed to roof 13, thereby causes the periodicity rolling of roof 13.Framework 79 and the roof 13 large axial stiffness on the longitudinal direction of container 10 makes any cyclical movement upwards be caused the party in roof 13 minimize.The cyclic force produced due to the eccentric weight 77 of rotation mainly is parallel to the plane of roof 13, so vibrating device 75 can inspire even-order harmonic at least substantially with on the rectangular direction of center line 73 in roof 13, but can not in roof 13, inspire significant odd harmonic, this is because odd harmonic need to apply the cyclic force perpendicular to the plane of roof 13.

An advantage of the vibrating device 75 of the rolling of the periodicity about its center line 73 of generation roof 13 is the following fact: this vibrating device 75 can fully directly be installed on roof 13.On the contrary, the vibrating device 75 that produces the periodicity vertical motion of center line 73 may need to be installed on the hard benchmark architecture in mechanical properties separated with container 10.In addition, with the vibrating device 75 of the periodicity vertical motion that produces center line 73, compare, the vibrating device 75 of the rolling of the periodicity about its center line 73 that produces roof 13 may be without undergoing same large internal force in operating process, and can have longer serviceable life.Finally, produce the vibration that the vibrating device 75 shaken is particularly suitable for inspiring even-mode in the roof 13 of container 10.

No matter one or more framing components 18 of container 10 whether as air conduit with the inside 66 that input air is transferred to container 10 or 66 to receive sample air internally, disclosed hereinly all about vibrating device 75 and with the content of the use of container 10, all can be applicable to any container 10.

Port 85-92 in the wall 13-15 of container 10

Go to now Figure 11-12, can see that container 10 can have one or more air delivery port 85-92 in its wall 13-15.One or more in described port 85-92 can have input air nozzle 94 or sample air delivery nozzle 95. Nozzle 94,95 can be used interchangeably, because nozzle 94 can be used as sample air delivery nozzle 94, and nozzle 95 can be used as input air nozzle 95.

The wall 13-15 of container 10 can not have port 85-92, has in port 85-92, or has two or more in port 85-92.Port 85-92 can be arranged in any suitable position in wall 13-15, in order to can operate with headroom 25 or side spaces 27 in the inside 66 of access set vanning 10.

The door 17 of container 10 can be provided with one or more port and the nozzles identical with port 85-92 or nozzle 94-95.

Although port 85-92 penetrates the wall 13-15 of container 10, port 85-92 might not penetrate the framework 18 of container 10.

Any specific port 85-92 can have any suitable size, structure and position; Can operate with the air as arrive the inside 66 of container 10 in order to transmit air or circulation sample air and input outside port 85-92; Perhaps can operate the sample air output outside port 85-92 that receives sample air with the inside 66 as from container 10.Any specific port 85-92 can have identical or different size and structure with any other port 85-92.

Any specific port 85-92 can have any suitable geometry or non-geometric configuration, as circle or rectangle.Any port 85-92 can have identical or different shape with any other port 85-92.If the input of the air in wall 14-15 outside port 87-92 has rectangular shape, this rectangular shape can have the ratio of width to height that is at least 3: 1 so, and can be positioned at the vertical distance of 10 times that is not more than about rectangular port 85-92 height with the roof 13 of container 10.If the air in wall 13 input outside port 85-86 is rectangle, this rectangle can have and is at least approximately the ratio of width to height of 3: 1 so.

When air input outside port 85-92 is described as having rectangular shape, means at least its exhaust openings that enters into the inside 66 of container 10 and there is rectangular shape, because what can expect is that it can have different shapes in its exhaust openings upstream.

The term " rectangle " used about the shape of the shape of the exhaust openings 96 of the shape of port 85-92, nozzle 94 and the air-spray that they produce as air input port or nozzle the time is broad sense, because their shape needs not be strict with rectangle.Therefore, about port 85-92 and exhaust openings 96, term " rectangle " is defined as and comprises any geometry or non-geometric configuration, as long as this shape comprehensive average the ratio of width to height on its width is at least approximately 3: 1.For example, even the top surface of air input outside port 85-92 or exhaust openings 96 and basal surface may be slightly arc, wriggle or zigzag, but not straight, air input outside port 85-92 or exhaust openings 96 can be still " rectangles " under above-mentioned definition.

Can be applied to equally any air input outside port 85-92 and any air input nozzle 96 about the circle of the laminar flow from air input internal port 47 and nozzle 48 and turbulence form and the disclosure of rectangular cross section air-flow above should be appreciated that.

From Figure 12, can see best, if the port 86 in the roof 13 of container 10 is air input outside ports 86, this port 86 can comprise the air input nozzle 94 of the exhaust openings 96 with the inside 66 for input air being transferred to container 10 so.Similarly, if the port 85 in the roof 13 of container 10 is sample air output outside ports 85, this port 85 can comprise having for 66 sample air delivery nozzles 95 that receive the sample air outlet opening 97 of sample air internally so.

Nozzle 94,95 can have any suitable size, shape and structure.Any specific nozzle 94,95 can have size, shape and the structure identical or different with any other nozzle 94-95; Any specific exhaust openings 96 can have the size and dimension identical or different with any other exhaust openings 96; And any specific sample air receives opening 97 can have the size and dimension identical or different with any other sample air reception opening 97.

From Figure 12, can preferably must see, sample air input nozzle 94 can the rectangular bending of tool, makes its exhaust openings 96 at least substantially meet at right angles with respect to the plane of roof 13.This makes exhaust openings 86 on the direction that at least is in substantially parallel relationship to roof 13, input air to be transferred in the headroom 25 in container 10, for query set vanning 10 better.

From Figure 12, can also see, sample air delivery nozzle 95 also can the rectangular bending of tool, makes its sample air outlet opening 97 at least substantially meet at right angles with respect to the plane of roof 13.This makes sample air outlet opening 97 to receive sample air by the headroom from container 10 25 on the direction that at least is in substantially parallel relationship to roof 13, for query set vanning 10 better.
