[0027] The bending tube 2 and the U-shaped tube 3 can be installed through the mounting plate 1. The bending tube 2 and the U-shaped tube 3 are connected to maintain the fluidity of the oil fume. At the same time, the oil fume detection tube 4 is installed at one end of the bending tube 2. The oil fume sensor 7 inside the oil fume detection tube 4 can detect the kitchen oil fume concentration. At the same time, the constant pressure control fan 5 is installed under the action of the U-shaped tube 3. The internal pressure of the pipeline can be controlled according to different kitchen oil fume concentrations through the constant pressure control fan 5 to ensure that the internal pressure of the pipeline is constant, thereby improving the stability and efficiency of oil fume emission. Since the oil fume sensor 7 is used for a long time, oil fume garbage is easily accumulated at the probe of the oil fume sensor 7. The horizontal position of the cleaning tube 9 can be controlled by the hydraulic cylinder 8. The cleaning tube 9 is in contact with the probe of the oil fume sensor 7, which is convenient for cleaning the oil fume sensor 7. At the same time, the cleaning tube 9 is easy to disassemble and assemble, which is convenient for users to disassemble and clean it regularly, thereby ensuring the service life of the product.

[0028] like Figure 1 As shown, the U-shaped tube 3 is connected to the bent tube 2 , and a solenoid valve 10 is disposed inside the U-shaped tube 3 .

[0029] The U-shaped tube 3 is connected to the bent tube 2. When the oil fume concentration and emission amount are large, the channel inside the U-shaped tube 3 is opened by the solenoid valve 10 to ensure the oil fume emission efficiency of the device.

[0030] like Figure 3 As shown, the output end of the U-shaped tube 3 is provided with a positioning frame 11 matching the constant pressure control fan 5 , and the top thread of the positioning frame 11 is provided with a positioning screw 12 in contact with the constant pressure control fan 5 .

[0031] Under the action of the U-shaped tube 3, the positioning frame 11 is installed, and then the constant pressure control fan 5 is placed inside the positioning frame 11. Then the positioning screw 12 is rotated to make the positioning screw 12 contact with the constant pressure control fan 5, so that the user can disassemble and assemble the constant pressure control fan 5. The constant pressure control fan 5 can control the internal pressure of the pipeline according to the concentration of kitchen fume, ensuring that the internal pressure of the pipeline is constant, thereby improving the stability and efficiency of fume emission.

[0032] like Figure 3 As shown, a guide hole 13 is provided at the top of the positioning frame 11, and a screw column 14 connected to the dust removal plate 6 is slidably provided inside the guide hole 13, and a screw cap is threadedly provided at one end of the screw column 14, and a limiting slot is provided on one side of the dust removal plate 6, and a dust removal brush plate 15 is provided inside the limiting slot.

[0033] The horizontal position of the screw column 14 is adjusted through the guide hole 13 at the top of the positioning frame 11. When the screw column 14 moves, it drives the dust removal plate 6 to slide inside the positioning frame 11.

[0035] The C-type plate 17 is installed through the C-type slide groove 16 inside the oil fume detection tube 4, and the hydraulic cylinder 8 is installed through the mounting hole inside the C-type plate 17. After the hydraulic cylinder 8 is installed, the working bolt is manually rotated to make the working bolt contact with the hydraulic cylinder 8, which is convenient for users to disassemble and assemble the hydraulic cylinder 8 and adjust the height of the C-type plate 17.

The hydraulic cylinder 8 drives the push plate 18 and the annular sleeve 19 to move horizontally. When the annular sleeve 19 moves horizontally, it drives the cleaning cylinder 9 to move, so that the oil smoke sensor 7 probe can be cleaned.

[0038] like Figure 4 As shown, an external threaded ring 20 is provided on the outer side of the oil fume detection tube 4, and a tube cover 21 is provided on the top of the oil fume detection tube 4. The outer thread of the tube cover 21 is connected with an internal threaded ring 22 matching the external threaded ring 20, and the internal thread of the tube cover 21 is penetrated by a working stud in contact with the C-shaped plate 17.

[0039] Place the tube cover 21 on the top of the oil fume detection tube 4, and rotate the internal threaded ring 22 on the outside of the tube cover 21. The internal threaded ring 22 rotates and descends. When the internal threaded ring 22 descends, it engages with the external threaded ring 20 on the outside of the oil fume detection tube 4. When the internal threaded ring 22 moves to the middle position between the external threaded ring 20 and the tube cover 21, the tube cover 21 can be stably installed. Then manually rotate the working stud to make the working stud contact with the C-type plate 17, so that the C-type plate 17 can be disassembled and assembled, thereby facilitating the user to disassemble and assemble the internal components of the oil fume detection tube 4.
