[0023] Specifically, refer to Figures 1 to 3The filtering mechanism includes a filter box 10, which is fixedly mounted on the bottom inner wall of the bottom frame 2, a negative pressure fan 9 is arranged on one side of the filter box 10, and a plurality of air pipes 12 are connected to the other side of the filter box 10, and a valve 4 is arranged inside the air pipe 12. The side wall of the filter box 10 is connected to a placement box 11, and an opening is provided on the side wall of the filter box 10 away from the placement box 11, and a mounting frame 13 is movably arranged in the opening, and two activated carbons 14 are arranged inside the mounting frame 13, one of which is located inside the placement box 11, and the other is located inside the filter box 10. An extraction mechanism is arranged on the side wall of the mounting frame 13, and the extraction mechanism includes a baffle 15, and two sealing gaskets are arranged on the outer wall of the mounting frame 13, and the two sealing gaskets are respectively located between the two activated carbons 14 and between the baffle 15 and one of the activated carbons 14, the side wall of the baffle 15 is fixedly connected to the side wall of the mounting frame 13, and a handle is fixedly installed on the side wall of the baffle 15 away from the mounting frame 13, and the side wall of the bottom frame 2 A rectangular groove 16 is provided on the wall, and the baffle 15 is adapted to the rectangular groove 16. After the quartz tube is melted, the valve 4 is opened, and under the action of the negative pressure fan 9, the harmful gas inside the electric furnace box 3 is driven to enter the interior of the filter box 10 through the air pipe 12, and then under the action of the activated carbon 14, the flue gas and harmful gas are adsorbed and filtered to avoid the harmful gas and flue gas remaining in the electric furnace box 3 being directly discharged into the environment, which has certain harm to the environment and the staff. When one of the activated carbons 14 has been used for a period of time, the handle can be pulled quickly to drive the baffle 15 to move, and the activated carbon 14 in the placement box 11 can be moved to the filter box 10. Then the staff replaces the used activated carbon 14. After the replacement is completed, the handle is pushed again to reset it, which is convenient for replacing the activated carbon 14; when two activated carbons 14 need to be replaced, the baffle 15 and the mounting frame 13 are pulled out of the rectangular groove 16, and the activated carbon 14 in the entire mounting frame 13 is replaced.

[0024] Further, refer to Figure 4 The lifting mechanism includes a gear 17. A mounting groove 6 is provided inside the box body 1. The gear 17 is rotatably installed inside the mounting groove 6. A handle 7 is provided on the side wall of the box body 1. One end of the handle 7 movably penetrates the bottom frame 2 and the side wall of the box body 1 and is fixedly connected to the side wall of the gear 17. A moving frame 18 is slidably installed inside the mounting groove 6. A plurality of gear teeth 19 are provided on the inner wall of one side of the moving frame 18. The plurality of gear teeth 19 are all meshed with the gear 17. The top of the moving frame 18 is hinged with a hinge column 5.

Under the action of the meshing transmission of the gear 17 and the plurality of gear teeth 19, the moving frame 18 is driven to move up. Because the electric furnace box 3 is hinged to the moving frame 18 through the hinge column 5, the electric furnace box 3 is adjusted to a desired angle.

[0028] The working principle of the utility model is as follows:

[0029] Before melting the quartz tube, the handle 7 is rotated to drive the gear 17 to rotate. Under the action of the meshing transmission between the gear 17 and the plurality of gear teeth 19, the moving frame 18 is driven to move upward. Since the electric furnace box 3 is hinged to the moving frame 18 through the hinge column 5, the electric furnace box 3 is adjusted to the required angle. After the melting is completed, the valve 4 is opened, and under the action of the negative pressure fan 9, the harmful gas inside the electric furnace box 3 is driven to enter the inside of the filter box 10 through the air pipe 12, and then under the action of the activated carbon 14, the smoke and harmful gas are adsorbed and filtered to avoid the residual harmful gas and smoke in the electric furnace box 3. The gas is directly discharged into the environment, which has certain hazards to the environment and the staff. When one of the activated carbons 14 has been used for a period of time, the handle can be pulled quickly to drive the baffle 15 to move, and the activated carbon 14 in the placement box 11 can be moved to the filter box 10. Then the staff can replace the used activated carbon 14. After the replacement is completed, the handle is pushed again to reset it, which is convenient for replacing the activated carbon 14. When two activated carbons 14 need to be replaced, the baffle 15 and the mounting frame 13 are pulled out of the rectangular groove 16 to replace the activated carbon 14 in the entire mounting frame 13.
