The beneficial effects of the utility model embody a concentrated reflection of, can quickly, intuitively detect concentration of formaldehyde, and it is at low cost,
It is easy to use.Specifically, the utility model in use, is first removed the lid on blast pipe and discharge pipe, so
After open air inlet fan, air inlet fan pumps outside air acceleration to shell, and the formaldehyde in air is absorbed by active carbon particle；Clearly
Clean air is discharged from discharge pipe.After continuing for some time, air inlet fan is closed, the lid on blast pipe and discharge pipe is installed
It is good, and detection liquid is poured into detection plate, the liquid level for detecting liquid need to not cross the outlet end of bend pipe；Then electric heating tube is opened
Active carbon particle is heated, the formaldehyde adsorbed in active carbon particle during heating quickly volatilizees, and is discharged into through bend pipe
It is reacted in detection liquid with detection liquid.User detects the color of liquid by observation, it can be learnt that active carbon in certain time
The formaldehyde amount that particle absorbs, and then intuitively find out the concentration of formaldehyde.The utility model structure is simple, at low cost, easy to carry.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of aeration plate.
Specific embodiment
A kind of portable Formaldehyde device in conjunction with shown in Fig. 1-2, including shell 1 in a rectangular parallelepiped shape, the shell 1
