When the circulating pump 90 and the sampling pipe 100 are simultaneously arranged, the connection sequence is air outlet 50-sampling pipe 100-circulating pump 90-air inlet 60, air inlet valve and air outlet valve are opened, the detector 80 and the circulating pump 90 are started, and then the pollutant concentration in the pollutant collecting chamber 10 can be collected in situ, so that the pollutant components and concentration can be analyzed, the pollution source can be determined rapidly, the building material sample does not need to be sent to a laboratory for detection, and the damage of the building material sample is prevented, as shown in fig. 3.
In some embodiments, the contaminant collection chamber 10 is hemispherical; the contaminant collecting chamber 10 is configured to be erected on the building material to be detected, and the end surface of the contaminant collecting chamber 10, which is configured to contact with the building material to be detected, is provided with a sealing member 301, as shown in fig. 1 to 3.
The pollutant collecting cabin 10 is hemispherical, the hemispherical structure is regular, the processing and forming are convenient, the attractiveness of the product is improved, and meanwhile, the pollutant collecting amount is improved.
The sealing element 301 (such as a sealing gasket or a sealing ring) is arranged on the end face of the pollutant collecting cabin 10, which is in contact with the building material to be detected, so that the sealing effect is achieved, the pollutants are prevented from being leaked from the end face of the pollutant collecting cabin 10, which is in contact with the building material to be detected, and the use safety of the product is further improved.
It is worth to say that the pollutant collecting cabin 10 can be made of metal, glass or quartz and the like, the cabin volume is 100 ml-1000L, and the pollutant adsorption can be effectively reduced through passivation treatment on the inner wall.
The building material pollutant in-situ detection device provided by the invention has the advantages that the building material sample to be detected is heated through the heating element to quickly release pollutants, the pollutants emitted by the building material to be detected are collected in situ by the pollutant collecting cabin, the pollutant components and the concentration of the pollutants are quickly detected by the in-situ pollutant detector, or the building material pollutants are collected in situ through the sampling pipe and are detected and analyzed, so that the pollution source of indoor air is quickly and accurately locked, a user can conveniently and quickly treat the pollution source in a targeted manner, the indoor air quality is improved, the pollution source detection step is simplified, the pollution source detection efficiency is improved, the building material sample is not damaged, the structure is simple, the installation is easy, and the popularization and the use are suitable.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
