Abstract
The invention discloses an air sampling head. The air sampling head comprises an air inlet head and an air outlet head, wherein the air inlet head comprises a tapered air inlet pipe and a spinning ring; the air outlet head comprises a round tube connection section, a tapered air outlet tube section and a threaded connection section; a limiting and fixing platform is arranged at the connecting part of the round tube connection section and the tapered air outlet tube section, and consists of a limiting part at the periphery and a fixing part connected with the limiting part; the fixing part is located below the limiting part and is a reticular ventilate fixing part. Owing to the unique integrated limiting and fixing part, a filter membrane can be not only better fixed, but also protected against damage; the air inlet head and the air outlet head are in threaded fit through the spinning ring and the round tube connection section, so that compared with the snap joint mode, the combination is tighter; as a rubber washer is arranged at the root of threads of the round tube connection section, the leak tightness is further enhanced.
Description
Technical field
The present invention relates to a kind of environmental monitoring apparatus, be specifically related to a kind of air sampling head.
Background technology
When detecting air quality, often utilize air sampler to wear air sampling head and carry out operation, with air sampler be driving source by air intake sampling head, the materials such as the filter paper of sampling head inside filter air, then the foreign material on filter paper are carried out separation detect.The common version of sampling head is one end is air intake opening, and the other end is the gas outlet be connected with sampling thief, and filter paper is placed on sampling head inside, therefore requires that sampling head middle part is the detachable structure be separated, is convenient to place the filtrate such as filter paper, filter membrane.
But, sampling head of the prior art is primarily of following shortcoming: 1. long-term sampling or the excessive wrinkle of filter paper or filter membrane that easily cause of sampling flow even damaged, 2. in prior art so the air inlet head that connects of buckle-type and give vent to anger that not only impermeability is bad for head, easily damage after repeatedly using, serviceable life is short.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of air sampling head, effectively can either avoid the damage of filter paper or filter membrane, can improve again the serviceable life of sampling head.
For solving the problem, the technical solution used in the present invention is:
A kind of air sampling head, comprise air inlet head and head of giving vent to anger, described air inlet head comprises tapered snorkel and spinning ring, described head of giving vent to anger comprises pipe linkage section, pipeline section and the section of being threaded are given vent to anger in taper, the give vent to anger junction of pipeline section of described pipe linkage section and taper is provided with spacing stationary platform, described spacing stationary platform is made up of the limiting section of periphery and the fixed part that is connected with described limiting section, and described fixed position is below described limiting section, and described fixed part is netted ventilative fixed part.
Preferably, the bottom margin of described tapered snorkel largest diameter stretches out formation one flanging, and described flanging width is equal with described limiting section width.
Preferably, described spinning ring inner surface is provided with internal thread, and the outside surface of described pipe linkage section is provided with the external thread adapted with spinning ring inner surface.
Preferably, the external thread root of described pipe linkage section is provided with a rubber washer.
Preferably, described tapered snorkel and described in an inside surface of giving vent to anger be slippery inner surface.
Preferably, described flanging lower surface is provided with some small embossments.
The beneficial effect that the present invention reaches:
Give vent to anger in head and be provided with spacing stationary platform to place filter paper or filter membrane, spacing stationary platform is made up of limiting section and fixed part, tapered snorkel wherein in limiting section and air inlet head coordinates to be pushed down filter paper or filter membrane edge, prevent filter membrane from moving, the Reticular breathable fixed part be positioned at below limiting section can play further protective effect to the filter paper of sampling or filter membrane, even if long-time sampling or air mass flow strengthen wrinkle, the disrepair phenomenon that also can reduce filter membrane or filter paper due to the protection of fixed part;
Air inlet head and give vent to anger head respectively by spinning ring and pipe linkage section threaded engagement, compare snap and combine more tight, the thread root of pipe linkage section is provided with rubber washer and further enhances sealing.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
As Figure 1-4, a kind of air sampling head, comprise air inlet head 1 and give vent to anger 3, air inlet head 1 comprises tapered snorkel 11 and spinning ring 2, giving vent to anger, 3 comprise pipe linkage section 4, pipeline section 5 is given vent to anger in taper and the section of being threaded 6, and the give vent to anger junction of pipeline section 5 of pipe linkage section 4 and taper is provided with spacing stationary platform 7, and spacing stationary platform 7 is made up of the limiting section 71 of periphery and the fixed part 72 that is connected with limiting section 71, fixed part 72 is positioned at below limiting section 71, and 72 fixed parts are netted ventilative fixed part.
Preferably, the bottom margin of tapered snorkel 11 largest diameter stretches out formation one flanging 12, and flanging 12 width is equal with limiting section 71 width.As further preferably, flanging 12 lower surface is provided with some small embossments, plays the effect of increasing friction force, is convenient to the fixing of filter paper or filter membrane.
Preferably, spinning ring 2 inside surface is provided with internal thread, and the outside surface of pipe linkage section 4 is provided with the external thread adapted with spinning ring 2 inside surface.The external thread root of pipe linkage section 4 is provided with a rubber washer, and rubber washer is the impermeability in order to improve when both screw.
Preferably, tapered snorkel 11 and 3 inside surface of giving vent to anger are slippery inner surface, and slippery inner surface is accumulation dust not easily, and permanent use is convenient to cleaning.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
