[0025] See Figure 3-5 and Figure 7Furthermore, the limiting mechanism includes a pressure plate assembly 6 and four plate slideways 5 fixedly connected to one end of the outer shell 1, and the four plate slideways 5 are symmetrical in pairs. The pressure plate assembly 6 includes a support plate 61, the top of the support plate 61 is fixedly connected to a transmission slide bar 64, both sides of the bottom end of the support plate 61 are fixedly connected to a pressure plate slider 62, one side of the support plate 61 is fixedly connected to a filter pressure plate 63, the surface of the pressure plate slider 62 is slidably connected to the inside of the plate slideway 5, the surface of the transmission slide bar 64 is slidably connected to the transmission mechanism, the surface of the transmission mechanism is provided with a slide groove assembly 9, the transmission mechanism includes a transmission column 7, one end of the transmission column 7 is provided with a transmission groove 8, the transmission column 7 The other end is fixedly connected to the transmission gear, the slide assembly 9 includes a slide block 91, a limiting hole 92 is provided in the middle of the slide block 91, and a support rod 93 is fixedly connected to the bottom of the slide block 91. One end of the support rod 93 is fixedly connected to the limiting swivel 94, and the interior of the limiting swivel 94 is rotatably connected to the surface of the transmission column 7. A spring latch 10 is fixedly installed on one side of the slide block 91, and the interior of the slide block 91 is slidably connected to the transmission tooth plate 11. Both sides of the top of the transmission tooth plate 11 are fixedly connected to the latch seat 12. The spring latch 10 passes through the limiting hole 92 and is plugged and fixed to the latch seat 12. One side of the transmission tooth plate 11 is meshed with one side of the transmission gear;

[0026] When in use, the pre-filter 2 is placed inside the filter slot 4, and then the spring latch 10 is pulled out. The spring latch 10 is a prior art. When the spring latch 10 is pulled out, the plug-in limit of the latch seat 12 and the limit hole 92 is released, and then the transmission tooth plate 11 can slide inside the slide block 91. When the transmission tooth plate 11 moves, it drives the transmission gear engaged with it to rotate. The transmission gear is installed at one end of the transmission column 7, and the transmission column 7 is installed inside the slide assembly 9.

Figure 6One end of each activated carbon plate 14 is fixedly connected to a guide baffle 15. The guide baffle 15 close to the oil fume inlet end allows the oil fume to enter the adsorption mechanism from the right side of the opening, and then the oil fume will present an S shape to the outlet. The other guide baffle 15 allows the oil fume to only be discharged from the outlet formed by the guide baffle 15 and the inner wall of the outer shell 1. The exhaust fan is installed on one side of the exhaust slot 16, which plays the function of drawing and discharging the oil fume.

Two activated carbon plates 14 are installed on the top of the adsorption bottom plate 13. The specific installation of the activated carbon plate 14 is shown in FIG. Figure 6 One end of each activated carbon plate 14 is fixedly connected to a guide baffle 15. The guide baffle 15 close to the oil smoke inlet end allows the oil smoke to enter the adsorption mechanism from the right side of the opening, and then the oil smoke will present an S shape to the outlet. The other guide baffle 15 allows the oil smoke to only be discharged from the outlet formed by the guide baffle 15 and the inner wall of the outer shell 1, increasing the contact area and contact time between the oil smoke and the activated carbon plate 14, and achieving better treatment effect.
