Description
Technical Field
The utility model relates to a portable formaldehyde detection device belongs to formaldehyde detection technical field.
Background
A large amount of formaldehyde exists in a newly decorated house, the formaldehyde is teratogenic and carcinogenic substances, gene mutation is caused by long-term contact, therefore, the detection of the formaldehyde becomes an important detection program before the new house is put into residence, the existing detection methods are mainly divided into two types, one is to sample on site and bring the sample back to a laboratory for analysis, the method has high detection precision, but the analysis period is long, the cost is high, and the steps are complicated, the other is to adopt a formaldehyde detection box on the market, put a reagent into a container, completely absorb the formaldehyde when air flows through the surface of the reagent, then the reagent reacts with the formaldehyde to generate color change, and quickly confirm the formaldehyde pollution degree by comparing the color with a colorimetric card, but because the reagent is always exposed in the air, the air flow flowing through the surface of the reagent in unit time cannot be ensured, and the influence of humidity, air pressure and air flow rate is extremely large in the process, thereby easily causing a large error in the detection result.
Disclosure of Invention
The utility model discloses the technical problem that will solve lies in: the portable formaldehyde detection device solves the problem that a reagent is influenced by other environmental factors to cause large detection result errors.
The utility model discloses the technical problem that will solve takes following technical scheme to realize:
the utility model provides a portable formaldehyde detection device, includes one end open-ended sleeve pipe, the sleeve pipe is transparent material, the sealed sliding connection of sheathed tube inner wall has the plug, fixedly connected with head rod and second connecting rod respectively at the both ends of plug, the one end of head rod extends to the sheathed tube opening outside, and fixedly connected with end cover, second connecting rod and the sealed sliding connection of sleeve pipe, and one end extends to the sheathed tube outside, the through-hole has been seted up on the plug, the inner wall fixedly connected with seal membrane of through-hole, open-ended one side fixedly connected with thimble that is used for pricking broken seal membrane is kept away from to the sheathed tube inner wall.
As a preferred example, a color comparison card is adhered to the outer side wall of the sleeve.
As a preferred example, the end cap is provided with a flange which is arranged in a sealing manner with the end of the sleeve.
The utility model has the advantages that: the utility model discloses a sheathed tube setting, the sealed storage of some indoor air of extraction is at the cover intraductal to take place the reaction with reagent in the cover, make the air in this unit not influenced by external environment factor, thereby reduce detection error, and the device sets up to disposable article, small gas, portable.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of the present invention when closed;
fig. 3 is a sectional view taken along line a-a of fig. 2.
In the figure: end cover 1, first connecting rod 2, seal membrane 3, colour comparison card 4, sleeve pipe 5, thimble 6, second connecting rod 7, reagent 8, plug 9.
Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.
As shown in fig. 1-3, a portable formaldehyde detection device, sleeve pipe 5 including one end open-ended, sleeve pipe 5 is transparent material, the sealed sliding connection of inner wall of sleeve pipe 5 has plug 9, the both ends of plug 9 are fixedly connected with head rod 2 and second connecting rod 7 respectively, the one end of head rod 2 extends to the opening outside of sleeve pipe 5, and fixedly connected with end cover 1, second connecting rod 7 and the sealed sliding connection of sleeve pipe 5, and one end extends to the outside of sleeve pipe 5, the through-hole has been seted up on the plug 9, the inner wall fixedly connected with seal membrane 3 of through-hole, the inner wall fixedly connected with thimble 6 that open-ended one side fixedly connected with was used for pricking broken seal membrane 3 is kept away from to sleeve pipe 5.
Adopt above-mentioned scheme, sleeve pipe 5 is optional with transparent plastic or transparent glass material, extracts partly indoor air through plug 9 and seals the storage in sleeve pipe 5 to react with reagent 8 in sleeve pipe 5, make the air in this unit not influenced by external environment factor, thereby reduce detection error, and the device sets up to disposable, small gas, portable.
The outer side wall of the sleeve 5 is stuck with a color comparison card 4.
Adopt above-mentioned scheme, prevent that colour comparison card 4 from losing at the in-process of carrying, the 8 colours of reagent of being convenient for simultaneously contrast with colour comparison card 4.
The end cover 1 is provided with a flanging, the flanging is arranged in a sealing mode with the end portion of the sleeve 5, and the sealing performance between the end cover 1 and the sleeve 5 is further enhanced.
The working principle is as follows: as shown in fig. 1, indoor pulling second connecting rod 7 right of waiting to detect, second connecting rod 7 drives plug 9, head rod 2 and end cover 1 remove, the opening extraction air through sleeve 5 when plug 9 removes, when plug 9 continuously moves to the right-hand member, seal membrane 3 contacts with thimble 6, and be punctured by thimble 5, reagent 8 that is located in plug 9 right side cavity at this moment floods into plug 9 left side cavity through the through-hole under the extrusion, meanwhile as shown in fig. 2, end cover 1 thoroughly covers the tip of sleeve 5, realize sealedly, reagent 8 then reacts with the formaldehyde in the extraction air, produce the direct contrast of colorimetric card 4 on the colour chip on the colour change back and the sleeve 5, thereby confirm the formaldehyde pollution degree fast.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
