Description

A kind of capturing device of portable air sensitization pollen

Technical field

The utility model relates to the monitoring and the analytical technology of air sensitization pollen contamination, is specifically related to a kind of capturing device of portable air sensitization pollen.

Background technology

Air sensitization pollen is the greatest factor that causes seasonal allergic airway disease, and the incidence of disease of China pollinosis patient in the crowd is about 0. 5～1%, and the highest morbidity area can reach 5%.In recent years, along with warming of global climate, the flowering of plant time shifts to an earlier date or delays, and the pollen cycle of sending out becomes unordered, and pollen sensitization patient's quantity has the trend that increases year by year, and pollinosis has become global environmental health problems.

Great mass of data shows that the incidence of disease of living in pollinosis among the crowd of air pollution area lives in incidence of disease height among the regional crowd that air do not polluted than those, and atmosphere fine grained and gaseous contaminant are (as NO _x, SO _x) be easy to be attracted on the pollen, the migration by pollen is deposited in nasal cavity and the eyes.There are some researches show that nitric acid gas exposes experiment and determines to be adsorbed with a lot of nitric acid on pollen, in the adsorbance of gas on the pollen than big many of those adsorbances on natural particle, humic acid and yellow sand; Find that simultaneously adsorbance increases along with the increase of exposed amount, so big adsorbance shows that nitric acid not only is adsorbed on the pollen surface, and is added in the pollen inside.Thereby, contain toxic pollutant such as heavy metal, acidic materials etc. just because of the pollen that disperses that is subjected to serious pollution, cause the pollinosis of metropolitan area.

At present, be that the device or the equipment of purpose also has many types, for example stand-type pollen nature gathering-device, vacuum pump type pollen gathering-device or the like to gather pollen.But all there is problem separately in they.For example stand-type pollen nature gathering-device owing to can only lean on pollen particles thing in the natural wind effect settle air, so its collection efficiency is very low and collection efficiency be subjected to the wind-force size influence and and unstable; On the other hand, can only sample by point of fixity, be inconvenient to carry.And against vacuum pump formula pollen gathering-device, because vacuum pump fair very big, and pump and capturing device separate, and will connect with pipeline during use, so be not easy to carry and very inconvenient use, usually also can only be as the pollen collection kit of fixed point sources.

The utility model content

Defective at the prior art existence, the purpose of this utility model provides a kind of capturing device of portable air sensitization pollen, avoided the heavy of common air particle gathering-device, inconvenience such as carries at shortcoming, have and to carry, be placed in the place that needs, collection efficiency advantages of higher easily.

For achieving the above object, the technical solution of the utility model is:

A kind of capturing device of portable air sensitization pollen comprises shell, pickup groove, power supply, motor, adhesive tape collection membrane, control system and flabellum, described shell is made up of two different cylindrical drum of diameter, and described pickup groove is installed in the cylindrical drum inside, rear end of described shell, and described power supply and motor are installed in the described pickup groove, described control system is positioned at the outside of the rear end cylindrical drum of described shell, control the on/off of whole device, sampling time, the flow velocity of sample frequency and air etc.; Described flabellum is installed in the nose circle column casing of described shell, is connected with described motor, and described adhesive tape collection membrane is positioned on the described shell front end cylinder inner wall.

The utility model has following outstanding advantage compared with prior art:

By the capturing device of a kind of portable air sensitization of utility model pollen, for the reaction of research air sensitization pollen and atmosphere pollution, understand influence and the mechanism of action thereof of atmosphere pollution to air sensitization pollen, important meaning is all arranged.The utility model device has been avoided the heavy of common air particle gathering-device, and inconvenience such as carries at shortcoming, follows integrated thought theory, and is small and exquisite portable, can be placed in the place that needs; Because lasting power system power supply is arranged, taking the initiative absorbs the enrichment particle, and the particle collection efficiency on the collection membrane improves greatly, and experimental data shows that collection efficiency can reach more than 90%.And the installation of collection membrane, it is simple to operate to win replacing etc.

Fig. 2 is a kind of capturing device when work gas flow synoptic diagram of portable air sensitization pollen.

Embodiment

Below in conjunction with the drawings and specific embodiments embodiment of the present utility model is described in further detail.

Referring to Fig. 1, a kind of capturing device of portable air sensitization pollen, comprise shell 4, pickup groove 1, power supply 2, motor 3, adhesive tape collection membrane 5, control system 6 and flabellum 7, described shell 4 is made up of two different cylindrical drum of diameter, described pickup groove 1 is installed in the cylindrical drum inside, rear end of described shell 4, described power supply 2 and motor 3 are installed in the described pickup groove 1, and described control system 6 is positioned at the outside of the rear end cylindrical drum of described shell 4, control the on/off of whole device, sampling time, the flow velocity of sample frequency and air etc.; Described flabellum 7 is installed in the nose circle column casing of described shell 4, is connected with described motor 3, and described adhesive tape collection membrane 5 is positioned on the described shell 4 front end cylinder inner walls.

Referring to Fig. 2, after the energized, the rotation of driven by motor flabellum will form negative pressure in device flabellum direction, the device front end air enters cylindrical drum, and air changes streamline flow to the particle collection membrane through flabellum when entering cylindrical drum, and particle is because the effect of sticking together of the adhesive tape on inertia and the inwall, particle is wherein collected by adhesive tape, after collection process finished, collection membrane was removed and is used for experimental analysis, can change new collection membrane when gathering again.
