[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 4 In this embodiment, an exhaust gas purification device that is easy to install is provided, including a box body 1, a fan 2 is installed on one side of the box body 1, and a connecting mechanism 3 is installed on the other side of the box body 1. The connecting mechanism 3 includes an air intake pipe 31, and a connecting cover 32 is fixedly connected to one end of the air intake pipe 31. A fastening ring 35 for fastening the exhaust pipe is slidably connected to one end of the air intake pipe 31, and clamping blocks 38 for clamping the exhaust pipe are installed on both sides of the fastening ring 35.

[0022] When in use, the connecting cover 32 is covered on one end of the exhaust pipe, and the fastening ring 35 is put on the outside of the exhaust pipe, and the fastening ring 35 is slid to the farthest end from the connecting cover 32, and the purification device is fixed to one side of the exhaust pipe by the clamping block 38, so that the exhaust pipe and the connecting cover 32 cannot be separated, and the fan 2 is started. The fan 2 sucks the exhaust gas discharged from the exhaust pipe into the box body 1. The exhaust gas is purified inside the box body 1 and then discharged from the box body 1 through the fan 2, and is discharged after being treated to meet the standards.

[0023] In further embodiments, see Figures 2-3 The fastening ring 35 is rotatably connected with a connecting screw 36, and a lifting rod 37 is threadedly connected to the outer side of the connecting screw 36. A connecting rod 39 is connected between the two ends of the lifting rod 37 and the pressing blocks 38 on both sides. The lifting rod 37 is lifted by rotating the connecting screw 36. The two ends of the lifting rod 37 need to be located inside the two ends of the outer side of the pressing block 38. When the lifting rod 37 is lifted, the two ends pull the upper end of the connecting rod 39 upward, and the lower end of the connecting rod 39 approaches the fastening ring 35. The lower end of the connecting rod 39 pushes the pressing block 38 to approach the inside of the fastening ring 35, and the pressing block 38 clamps the exhaust pipe.

[0024] In further embodiments, see Figure 3 The pressing block 38 includes a connecting block 381, one end of which is slidably connected to a sliding block 382, ​​and a spring 383 is connected between the sliding block 382 and the connecting block 381. The connecting rod 39 pushes the connecting block 381 to approach the middle of the fastening ring 35, and the connecting block 381 compresses the spring 383, and the spring 383 drives the sliding block 382 to approach the exhaust pipe in the middle of the fastening ring 35 through elastic force, so that one end of the sliding block 382 clamps the exhaust pipe.

[0025] In further embodiments, see Figures 2-3The lower end of the air intake pipe 31 is fixedly connected with a connecting piece 33, and the lower end of the connecting piece 33 is slidably connected with a sliding frame 34. The upper end of the sliding frame 34 is fixedly connected with a fastening ring 35, and the two sides of one end of the sliding frame 34 are rotatably connected with fixed pulleys 310. The two ends of the connecting piece 33 are fixedly connected with steel cables 311, and one end of the steel cables 311 is connected to the lifting rod 37 by passing through the fixed pulley 310. The lifting rod 37 also pulls one end of the steel cable 311 to rise during the rising process, and the other end of the steel cable 311 thereby pulls the connecting piece 33 to move, so that the air intake pipe 31 and the connecting cover 32 on the connecting piece 33 are closer to the exhaust pipe and fit the exhaust pipe more closely.

[0026] In further embodiments, see Figures 2-3 The lifting rod 37 is provided with a plug hole 371, one end of the steel cable 311 is fixedly connected with a plug, and one end of the plug is inserted into the plug hole 371. The connection state between the steel cable 311 and the lifting rod 37 can be changed by the plug, so that when the diameter of the exhaust pipe is relatively small, the connecting bolt 36 can be screwed alone to raise the lifting rod 37, and the pressing block 38 can be driven by the lifting rod 37 to press the exhaust pipe, so that one end of the steel cable 311 is inserted into the lifting rod 37, and the steel cable 311 is driven to rise by the lifting rod 37.

[0027] It should be noted that the deformation length inside the pressing block 38 needs to be greater than the distance that one end of the steel cable 311 can rise, so as to ensure that the tensioning action is completed within the deformation range of the pressing block 38.

[0028] In a further embodiment, the air inlet pipe 31 and the fan 2 are both connected to the interior of the box 1, and a purification mechanism is installed inside the box 1. The purification mechanism includes a filter layer, an activated carbon layer and other filtering structures. It is ensured that the exhaust gas can enter the interior of the box 1 through the air inlet pipe 31, and is purified by the purification mechanism inside the box 1 and then discharged from the box 1 through the fan 2.

[0029] In further embodiments, see Figure 4 A sealing plug 321 is fixedly installed inside the connection cover 32. The sealing plug 321 is annular, and an inner end of the sealing plug 321 forms a slope. The slope formed by the sealing plug 321 can cope with exhaust pipes of different diameters.

[0030] The shapes of the connection cover 32 and the sealing plug 321 are similar to the shapes of the exhaust pipe port, thereby ensuring that the end wall of the exhaust pipe can be tightly against the sealing plug 321 .

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
