Turn on the fan 5 to allow the formaldehyde-containing gas to enter the test chamber 1 and the control chamber 2 through the connecting pipe 3. After the gas enters the test chamber 1, it flows to the bottom of the test chamber 1 through the filter screen 104 under the action of the fan 5. After being absorbed by the filter screen 104, the filtered gas will drift into the transparent bucket 105 and react with the test reagent to produce a color reaction. By comparing the color of the reagent in the transparent bucket 105 with the color of the reagent in the control bucket 6, the effect of the filter screen 104 in absorbing formaldehyde can be intuitively felt, which solves the problem that the staff cannot intuitively feel the formaldehyde filtration effect when using gas sensors.

[0022] Please see Figure 1 and Figure 4 In this embodiment, the connecting tube 3 is inverted U-shaped, and the other end of the connecting tube 3 is fixedly connected to the control box 2. The bottom of the inner wall of the control box 2 is fixedly connected to the control bucket 6. The lower end of the test box 1 is fixedly connected to multiple support columns 7. The front end of the test box 1 is hinged to a sealing door 8. The front end of the sealing door 8 is fixedly connected to an observation window 9. The front edge of the sealing door 8 is fixedly connected to a first handle 10. By setting the observation window 9, the change of reagent color can be observed in real time during the test. By setting the control bucket 6, the formaldehyde concentration in the test box 1 can be determined by the change of color.

[0023] Please see Figure 2In this embodiment, a first motor 106 is fixedly connected to the lower end of the test chamber 1. The output shaft of the first motor 106 passes through the lower end of the test chamber 1 and is fixedly connected to a rotating rod 107. Multiple stirring rods 108 are fixedly connected to the outer wall of the rotating rod 107. The multiple stirring rods 108 are evenly distributed on the outer wall of the rotating rod 107.

The slider 204 is slidably arranged on the outer wall of the screw 203. The cleaning plate 205 is fixedly connected to the front end of the slider 204. The bristles at the lower end of the cleaning plate 205 are in contact with the upper surface of the filter screen 104. After filtering for a period of time, the filter screen 104 may be clogged by impurities in the gas. At this time, by starting the second motor 202, the slider 204 drives the cleaning plate 205 to move left and right to clean the impurities on the surface of the filter screen 104, thereby avoiding the problem of filter screen 104 clogging causing errors in experimental results.

[0025] Please see Figure 2 In this embodiment, the dust removal assembly also includes a first trough 206, a collection box 207, a second trough 208, a dust storage box 209, and a second handle 210.

By providing the dust storage box 209, the impurities cleaned by the cleaning plate 205 can be stored. After the test is completed, the dust in the dust storage box 209 is centrally processed.

[0026] In use, the test reagent is first poured into the transparent container 105 and the control container 6, and the sealing door 8 is closed. Then, the fan 5 is turned on, so that the gas mixed with formaldehyde enters the test chamber 1 and the control chamber 2 through the connecting pipe 3 respectively. After the gas enters the test chamber 1, under the action of the fan 5, the gas will flow to the bottom of the test chamber 1 through the filter screen 104. After being absorbed by the filter screen 104, the filtered gas will drift into the transparent container 105 and react with the test reagent in color. By starting the first motor 106, the rotating rod 107 drives the stirring rod 108 to fully mix the gas and the test reagent, thereby improving the reaction efficiency. By comparing the color of the reagent in the transparent container 105 with the color of the reagent in the control container 6, the effect of the filter screen 104 in absorbing formaldehyde can be intuitively felt, which solves the problem that the staff cannot intuitively feel the formaldehyde filtration effect when using gas sensors.

[0027] After filtering for a period of time, the filter screen 104 may become clogged by impurities in the gas. At this time, by starting the second motor 202, the slider 204 drives the cleaning plate 205 to move left and right to clean the impurities on the surface of the filter screen 104, thereby avoiding the problem of filter screen 104 clogging causing errors in the experimental results.
