Abstract
The present invention relates to a kind of formaldehyde examination devices.Including detecting body (1), being provided with one on the outside of detection body (1) will test the seal closure (2) that body (1) closes, the position of corresponding detection body (1) display screen of the seal closure (2) is transparent setting, is provided with air entry (3) on the seal closure (2).The present invention, which is provided with, will test the seal closure that body closes, when detecting formaldehyde in this way, gas can be first drawn into inside seal closure, the gas being drawn into seal closure in this way is in an opposite static state, the concentration of formaldehyde that formaldehyde examination device detects in this way will be relatively accurate, structurally reasonable, detection is accurate.
Description
Technical field
The present invention relates to a kind of formaldehyde examination device, term environmental detection set technical fields.
Background technique
Formaldehyde is especially influenced on child very big an important factor for being detrimental to health；When house decoration because it is existing very
More materials it is living more or it is few all contain some formaldehyde, therefore the content of formaldehyde in house detected before inhabitation just seem have very much
Necessity, therefore various formaldehyde examination devices just come into being, but due to the influence of the various factors such as wind, the detection of formaldehyde
Precision is a greater impact, or very big in the fluctuation of same place detection data, therefore in order to improve detection accuracy, needs PARA FORMALDEHYDE PRILLS(91,95)
Detection device makes some improvement.
Summary of the invention
The present invention is in view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of a kind of structurally reasonable, first of raising formaldehyde examination precision
Aldehyde detection device.
Thus the technical solution adopted by the present invention is that: the present invention includes detection body (1), is set in the detection body (1) outside
Being equipped with one will test the seal closure (2) that body (1) closes, and the position of corresponding detection body (1) display screen of the seal closure (2) is
Bright setting is provided with air entry (3) on the seal closure (2).
The detection body (1) is coated on interior, the seal closure (2) and detection body (1) each face by the seal closure (2) completely
Equal gap setting.
It is provided with telescopic rod (5) and realizes connection across the seal closure (2) and detection body (1).
The connecting portion of the telescopic rod (5) and seal closure (2) is provided with gasket (4).
The invention has the advantages that 1) of the invention be provided with will test the seal closure that body closes, it, can when detecting formaldehyde in this way
Gas to be first drawn into inside seal closure, the gas being drawn into seal closure in this way is in an opposite static state, this
The concentration of formaldehyde that sample formaldehyde examination device detects will be relatively accurate, structurally reasonable, and detection is accurate；
2) present invention is further provided with gasket in the connecting portion of seal closure and detection body, and the presence of gasket improves close
Sealing performance between sealing cover and detection body；
3) there are gap settings for seal closure of the present invention and detection each face of body, are keeping seal closure internal gas metastable in this way
Meanwhile also guaranteeing certain flow regime, more it is further ensured that the accuracy of formaldehyde examination；
4) present invention is additionally provided with telescopic rod, and the presence of telescopic rod facilitates operator to manage detection device, thus for detection first
Aldehyde provides bigger convenience.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
1 it is detection body in figure, 2 be seal closure, 3 be air entry, 4 be gasket, 5 is telescopic rod.
Specific embodiment
The present invention includes detection body 1, and being provided with one on the outside of the detection body 1 will test the seal closure 2 that body 1 closes,
The position of corresponding detection 1 display screen of body of the seal closure 2 is transparent setting, is provided with air entry 3 on the seal closure 2.
In the detection body 1 is coated on by the seal closure 2 completely, the seal closure 2 and the detection 1 equal gap in each face of body are set
It sets.
It is provided with telescopic rod 5 and passes through the seal closure 2 and the detection realization connection of body 1.
The connecting portion of the telescopic rod 5 and seal closure 2 is provided with gasket 4.
The course of work of the invention are as follows: a part of gas is sucked by air entry 3 first, then closes air entry 3, then
Open detection body 1 carries out the concentration of formaldehyde detection to gas, after detection, then changes one place, re-starts above-mentioned step
It is rapid.
The transparent setting in 2 surface of seal closure of the present invention, its purpose is to intuitively observe the concentration of formaldehyde.
Telescopic rod 5 is arranged in the present invention, and the presence of telescopic rod 5 then makes to operate more convenient.
Claims (4)
