Description
Technical field
The present invention relates to detection field, more particularly to a kind of air acquisition syringe with slow-release function.
Background technology
With the exacerbation of global environmental pollution, soil, river and air pollution all had a strong impact on people production and
Life, various countries are all strengthening the comprehensive regulation of environment.
The comprehensive regulation of environment be unable to do without detection, and in environment measuring field, the detection of air quality is than more conventional inspection
Survey project.The collection of air can carry out scene pumping collection using glass needle tubing, be then placed on vertically in tool box and transport
Checked to laboratory, avoid extraneous air from entering syringe using the air part effusion in the self-weight press syringe of piston
It is interior, but part transport distance is oversize, and the air in syringe remains little, and have impact on normal detection.
The content of the invention
The present invention solves the technical problem of a kind of air acquisition syringe with slow-release function is provided, syringe is adjusted
The decrease speed of piston, reduces inner air loss.
In order to solve the above technical problems, one aspect of the present invention is：There is provided a kind of with slow-release function
Air acquisition syringe, including：Outside cylinder and piston barrel, the piston barrel are extended in outside cylinder from top, described
Piston barrel top is provided with push pedal, and the outside cylinder top is provided with a circle limiting plate, between the limiting plate and push pedal
The air bag of a snare tubular is provided with, the side of the air bag is provided with blast pipe, air door is provided with the blast pipe,
The outside cylinder body bottom is provided with the air intake duct connected with outside cylinder lumen, and the air-breathing pipe end is arranged with closure.
In a preferred embodiment of the present invention, the limiting plate, outside cylinder and the integrated glass structure of air intake duct.
In a preferred embodiment of the present invention, the air bag is set on piston barrel.
In a preferred embodiment of the present invention, the closure is elastic silica gel upper shield.
In a preferred embodiment of the present invention, the cylindrical upper evagination of the air intake duct is provided with a circle convex tendon.
In a preferred embodiment of the present invention, groove corresponding with convex tendon is provided with the closure.
The beneficial effects of the invention are as follows：A kind of air acquisition syringe with slow-release function that the present invention is pointed out, at the scene
Blast pipe is inflated using inflator so that air bag expands between limiting plate and push pedal, the expansion of air bag drives push pedal to rise,
Push pedal drives the pull of piston barrel and air is collected in outside cylinder, and closure is then arranged on air-breathing pipe end,
Outside cylinder is placed in tool box vertically so that the air in air bag is slowly released under the gravity compressing of push pedal and piston barrel
Put, adjust the size of air door to change deflation speed, so as to change the decrease speed of piston barrel, it is to avoid its lower reduction of speed
Fast and collection in excessive loss's outer barrel body air is spent, easy to operate, control is flexible, and the loss for gathering air is small, air
Acquisition precision be guaranteed.
Brief description of the drawings
Technical scheme in order to illustrate more clearly the embodiments of the present invention, below will be to that will make needed for embodiment description
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for
For those of ordinary skill in the art, on the premise of not paying creative work, other can also be obtained according to these accompanying drawings
Accompanying drawing, wherein：
Fig. 1 is a kind of structural representation of the preferred embodiment of air acquisition syringe one with slow-release function of the present invention.
Specific embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model of present invention protection
Enclose.
Fig. 1 is referred to, the embodiment of the present invention includes：
A kind of air acquisition syringe with slow-release function, including：Outside cylinder 1 and piston barrel 2, the piston barrel 2 from
Top is extended in outside cylinder 1, and the top of the piston barrel 2 is provided with push pedal 21, and the outside top of cylinder 1 is provided with one
Circle limiting plate 11, is provided with the air bag 4 of a snare tubular, the outside bottom of cylinder 1 between the limiting plate 11 and push pedal 21
The air intake duct 12 with the inner space of outside cylinder 1 is provided with, can be both evacuated using artificial pull push pedal 21, it is also possible to profit
The outer shift-in row pumping of push pedal 21 is caused with the inflation of air bag 4.
The side of the air bag 4 is provided with blast pipe 5, and air door 6 is provided with the blast pipe 5, changes air valve
The aperture of door 6, can adjust the exhaust velocity of blast pipe 5, that is, the speed that control push pedal 21 and piston barrel 2 decline, outward
A small amount of air effusion in portion's cylinder 1, can avoid extraneous air from entering outside cylinder 1.
The end of the air intake duct 12 is arranged with closure 3, and the closure 3 is elastic silica gel upper shield, is set in air intake duct
12 ends avoid the leakage of air, elastic silica gel upper shield it is elastic good, and air is not polluted, will not introduce to detection
Unfavorable factor.
The limiting plate 11, outside cylinder 1 and the integrated glass structure of air intake duct 12, sound construction, transparency are high, clearly
Clean convenience.
The air bag 4 is set on piston barrel 2 so that the location comparison of air bag 4 is fixed, and the expansion of air bag 4 and
Compression is limited, and can only be expanded or be compressed along the axial direction of piston barrel 2, improves the stability for using.
The cylindrical upper evagination of the air intake duct 12 is provided with a circle convex tendon 13, is provided with the closure 3 and convex tendon 13 pairs
The groove answered, the cooperation of convex tendon 13 and groove improves the air-tightness of closure 3, it is ensured that the No leakage in transport of air intake duct 12
Or air enters.
In sum, a kind of air acquisition syringe with slow-release function that the present invention is pointed out, operation is flexible, thus it is possible to vary
The decrease speed of piston barrel 2, both ensure that the precision of air acquisition, turn avoid that gathered air consumption is excessive to ask
Topic, improves the convenience of transport.
Embodiments of the invention are the foregoing is only, the scope of the claims of the invention is not thereby limited, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright description is made, or directly or indirectly it is used in other related technology necks
