[0029] A fixing ring 3 is arranged on the inner side of the connecting ring 21, a filter screen 32 is fixedly installed on one end of the fixing ring 3, a mounting frame 34 is fixedly installed on the other end of the fixing ring 3, a plurality of top plates 35 are arranged on the top of the mounting frame 34, a metal mesh cover 37 is fixedly installed on the bottom of the plurality of top plates 35, and activated carbon 38 is arranged on the inner side of the metal mesh cover 37.

[0030] Connecting rods 11 are fixedly mounted on the top and bottom of the first air intake frame 1 and the second air intake frame 12 .

[0031] A sealing ring 31 is fixedly mounted on the outer side of the fixing ring 3 , and the outer side of the sealing ring 31 is in contact with the inner side of the connecting ring 21 .

[0032] A support rod 33 is fixedly mounted on the top and bottom of the other end of the fixing ring 3 , and the support rod 33 is fixedly mounted on the inner side surface of the mounting ring 13 .

[0033] A handle 36 is fixedly mounted on the top of the top plate 35 .

[0034] The two support rods 33 can limit the fixing ring 3 when in use to prevent the fixing ring 3 from moving, and a sealing ring 31 is sleeved on the outer side of the fixing ring 3 to increase the sealing between the connecting ring 21 and the fixing ring 3;

[0035] The bellows 2 can be contracted when in use;

[0036] By installing the connecting rod 11 between the first air intake frame 1 and the second air intake frame 12, the first air intake frame 1 and the second air intake frame 12 can be fixed in position when in use;

[0037] When in use, the metal mesh cover 37 is arranged on the inner side of the mounting frame 34, and the top plate 35 is pressed on the top of the mounting frame 34, thereby playing a sealing role;

[0038] The filter screen 32 is mounted on one side of the fixing ring 3 by means of bolts.

[0039] The working principle of the magnetic core exhaust gas treatment device provided by the utility model, which is easy to replace the filter element, is as follows:

[0040] When the filter 32 and the activated carbon 38 need to be replaced after long-term use, the user can rotate the thread ring 22 to rotate the thread ring 22 on the outer side of the connecting ring 21, and make the thread ring 22 threadedly connected to the inner side of the thread groove 23 until the thread ring 22 is threaded out of the inner side of the thread groove 23, and then the user pushes the connecting ring 21 toward one end of the mounting ring 13, at which time the connecting ring 21 is separated from the outer side of the sealing ring 31, and at the same time the mounting frame 34 is exposed from the inner side of the corrugated pipe 2;

[0041] Then the user lifts the handle 36 upward, thereby driving the bottom of the top plate 35 away from the top of the installation frame 34, and moving the metal mesh cover 37 out from the inner side of the installation frame 34. At this time, the user can replace the metal mesh cover 37 and the activated carbon 38 inside. Then the user removes the filter screen 32 from one side of the fixing ring 3 for replacement.

[0042] After the replacement is completed, the user moves the threaded ring 22 to one end of the threaded groove 23, so that the threaded ring 22 is threadedly connected to the inner side of the threaded groove 23, and one end of the connecting ring 21 is against one side of the first air intake frame 2, and the connecting ring 21 is located on the outer side of the sealing ring 31 to play a sealing role. When used subsequently, the magnetic core exhaust gas enters through the first air intake frame 1, and then passes through the filter 32 to enter the inner side of the installation frame 34, and then enters the inner side of the second air intake frame 12 after being filtered through the activated carbon 38.

[0043] Compared with the related art, the magnetic core exhaust gas treatment device provided by the utility model, which is easy to replace the filter element, has the following beneficial effects:
