A sink 2 is disposed between the inner side panel 1 and the outer side panel. The inner side panel 1 has a first mounting hole 11, and mounting protrusions 12 are provided on both sides of the first mounting hole 11. The front of the sink 2 has a first flange 21 that mates with the first mounting hole 11. The first flange 21 presses against the first mounting hole 11, preventing the sink 2 from falling between the inner side panel 1 and the outer side panel. Six limiting posts 25 are provided on both sides of the back of the first flange 21. The six limiting posts 25 are symmetrically distributed from left to right. Each limiting post 25 includes a connecting part and a limiting part. One end of the connecting part is connected to the back of the first flange 21. The other end of the connecting part is connected to the limiting part. The limiting post 25 and the first flange 21 form a mounting groove 251. The mounting groove 251 is downward and funnel-shaped. The mounting protrusion 12 is inserted into the mounting groove 251 from bottom to top, thereby restricting the lateral movement of the basin 2 and preventing the basin 2 from moving downward. The top of the basin 2 is provided with a top post 24 fixedly connected to it. The upper part of the first flange 21 is provided with a fixing hole 241.

During the experiment, the user can clean the side panel of the fume hood at any time. The back of the basin 2 is provided with a protrusion caused by the cleaning groove 22. The water basin 2 has four equidistantly arranged air nozzles 231 on its front side, which are located on the upper part of the cleaning tank 22. The water basin 2 has a connecting groove 23 on its back side, and a second connecting pipe 232 is provided in the connecting groove 23. One end of the second connecting pipe 232 is connected to the air nozzle 231, and the other end of the second connecting pipe 232 is connected to an external air source. The four air nozzles 231 correspond to the four second connecting pipes 232. Users can choose whether to install the air nozzles 231 according to the actual situation, or they can add the air nozzles 231 later, which is convenient for installing the air nozzles 231 in the fume hood where air is needed.

[0028] Example 2: Figures 7 to 11As shown, a fume hood water basin installation structure includes a baffle plate 3 and a back plate 4 on the fume hood. A water basin 2 is disposed between the baffle plate 3 and the back plate 4. The baffle plate 3 has a second mounting hole. The front of the water basin 2 has a first flange 21, which engages with and presses against the second mounting hole to prevent the water basin 2 from falling between the baffle plate 3 and the back plate 4. The water basin 2 has a second flange 26, which is located behind the first flange 21. The second flange 26 is fixedly connected to the back plate 4 by screws, ensuring a secure connection. The upper part of the first flange 21 has a fixing hole 241. The water basin 2 has a top post 24, which is fixedly connected to the water basin 2 by bolts. The fixing hole 241 is elongated.
