Detailed description of the invention
Below in conjunction with the accompanying drawings and air microbe liquid cleaner is described further by specific embodiment.
With reference to Fig. 1, Fig. 2 and Fig. 3, air microbe Liquid sampler 10 includes sampling bottle 12, with
And the escape pipe 14 connected with sampling bottle 12.Sampling bottle 12 is cylindrical structural, the equal opening in two ends, gives vent to anger
Pipe 14 connects with sampling bottle 12.
Air microbe Liquid sampler 10 also include top cover 100, tail-hood 200, liquid injection pipe 300 and every
Plate 400.
Wherein, top cover 100 and tail-hood 200 two ends with sampling bottle 12 respectively are connected, escape pipe 14
On top cover 100.
Liquid injection pipe 300 is positioned at sampling bottle 12 inside and extends through top cover 100 and tail-hood 200, and fluid injection
Pipe 300 protrudes from top cover 100.
Liquid injection pipe 300 protrudes from one end of top cover 100 and is provided with screw thread.Adopt when needs inject in sampling bottle 12
During sample liquid, liquid injection pipe 300 is threadeded with the catheter (not shown) for water conservancy diversion sample solution；Work as needs
When being passed through air in sampling bottle 12, liquid injection pipe 300 and the air inlet pipe (not shown) spiral shell for importing air
Stricture of vagina connects.Namely liquid injection pipe 300 has fluid injection and two kinds of functions of air inlet, such that it is able to avoid at top cover simultaneously
Air inlet pipe is set on 100.This design simplifies the structure of air microbe Liquid sampler 10 so that produce,
Assembly and disassembly are more convenient.Being appreciated that in other embodiments, air inlet pipe and catheter also can divide
It is not arranged on top cover 100.
The liquid injection hole 310 of multiple uniform intervals distribution is offered on liquid injection pipe 300.Liquid injection hole 310 is around liquid injection pipe
300 be circumferentially arranged.
It is axially extending that dividing plate 400 is evenly distributed in the circumference of liquid injection pipe 300 and along liquid injection pipe 300.Every
Plate 400 fits tightly with the inwall of sampling bottle 12, and the inner chamber of sampling bottle 12 is divided into multiple chamber.Dividing plate
The two ends of 400 fit tightly with top cover 100 and tail-hood 200 respectively.Dividing plate 400 at top cover 100 also
Offer gas port 410, each chamber that gas port 410 is separated by dividing plate 400 for connection.And relative to
Liquid injection hole 310, gas port 410 is closer to top cover 100.In the present embodiment, dividing plate 400 is four,
The inner chamber of sampling bottle 12 is divided into four chambers by dividing plate 400, and gas port, by four chamber, enters sampling
Air in bottle 12 can be by multiple times of filtration when by each chamber, thus the microorganism in air is able to fully
Enrichment.Being appreciated that in other embodiments, the quantity of dividing plate 400 can also be 2,3,
5 or more, can the quantity of concrete decision dividing plate as the case may be.
Further, liquid injection pipe 300 is one-body molded with dividing plate 400, ease of assembly and dismounting.In each chamber
3 liquid injection holes, i.e. liquid injection hole 310 are distributed and have 12.And it is positioned at 3 liquid injection holes of same chamber
Line curved.When being passed through air in sampling bottle 12, can be driven respectively by the air of liquid injection hole 310
Sample solution in chamber rotates and forms whirlpool, thus increases the contact area of air and sample solution, improves micro-life
The collection efficiency of thing.Being appreciated that in other embodiments, the multiple liquid injection holes in each chamber also may be used
It it is a long and narrow arcuate socket.
As it is shown in figure 1, top cover 100 includes cover plate 110 and buffer body 120.Cover plate 110 is in tabular.
Cover plate 110, buffer body 120 are sequentially connected with sampling bottle 12.Cover plate 110 and buffer body 120 enclose formation
Cushion chamber 122.As in figure 2 it is shown, buffer body 120 offers gas outlet 124 away from the side of cover plate 110.
Gas outlet 124 is by cushion chamber 122 and the chamber in sampling bottle 12.
Escape pipe 14 is installed on cover plate 110 and inserts in cushion chamber 122, and passes through gas outlet 124 and adopt
Sample bottle 12 connects.In other embodiments, escape pipe 14 can also removably connect with cover plate 110.
The curved baffle 126 around trachea 14 it is provided with in buffer body 120.This baffle plate 126 and gas outlet 124
Laying respectively at the both sides of buffer body 120, position is separate.The two ends of baffle plate 126 and buffer body 120
Sidewall connects, i.e. escape pipe 14 is positioned at the containing cavity enclosed by the sidewall of baffle plate 126 with buffer body 120
In.And the height of baffle plate 126 is less than the height of buffer body 120, namely containing cavity is even with cushion chamber 122
Lead to.So, escape pipe 14 just connects with cushion chamber 122, and then connects with sampling bottle.Separately, by setting
Put baffle plate 126 and can effectively avoid the blister sucking-off from escape pipe 14 in sample solution.Meanwhile, giving vent to anger
Can be provided in pipe 14 intercepting the material-structures such as the web plate of sample solution blister, cotton-wool, can preferably avoid
Blister sucking-off from escape pipe 14.
Tail-hood 200 is cone structure.Liquid injection pipe 300 is through tail-hood 200 and in the end near tail-hood 200
Being provided with opening, this end is additionally provided with the pipe cap 210 for closing opening.After having gathered microorganism, open pipe
Cap 210, sample solution will be flowed out near the end of tail-hood 200 by liquid injection hole 310.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, the most right
The all possible combination of each technical characteristic in above-described embodiment is all described, but, if these skills
There is not contradiction in the combination of art feature, is all considered to be the scope that this specification is recorded.
Embodiment described above only have expressed several embodiments of the present utility model, its describe more concrete and
In detail, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that, it is right
