[0028] Referring to Figure 5 , a moving groove 212 is formed in the inner cavity of the fixing plate 208. A guiding rod 213 is movably connected to the inner cavity of the moving groove 212. One side of the guiding rod 213 is fixedly connected to the inner cavity of the moving groove 210. Through the arrangement of the guiding rod 213, it plays a guiding role in the movement of the fixing plate 208, preventing the position of the fixing plate 208 from shifting during the movement.

[0029] Referring to Figure 5 , a limiting groove 211 is formed in the inner cavity of the moving groove 212. A limiting plate 215 is movably connected to the inner cavity of the limiting groove 211. One side of the limiting plate 215 is fixedly connected to the surface of the guiding rod 213. Through the arrangement of the limiting plate 215, it plays a limiting role in the movement of the fixing plate 208, preventing the fixing plate 208 from detaching from the surface of the guiding rod 213 during the movement.

[0030] Referring to Figure 5 , a spring 214 is fixedly connected to one side of the fixing plate 208. The other side of the spring 214 is fixedly connected to the inner cavity of the moving groove 210. The inner cavity of the spring 214 is sleeved on the surface of the guiding rod 213. Through the arrangement of the spring 214, it plays a supporting role for the fixing plate 208, so that when the fixing plate 208 is not blocked, it can push the fixing plate 208 to move.

[0031] Referring to Figure 3 and Figure 4 , the bottom of the positioning plate 206 is rounded. The surface of the fixing plate 208 is rounded. The bottom of the positioning plate 206 is movably connected to the surface of the fixing plate 208. Through the rounded settings of the positioning plate 206 and the fixing plate 208, during the movement of the positioning plate 206, it will push the fixing plate 208 to contract inward, preventing the fixing plate 208 from blocking the entry of the positioning plate 206 into the inner part of the positioning groove 209.

[0032] Referring to Figure 1 、 Figure 2 、 Figure 6 and Figure 7, a smoke exhaust mechanism 3 is installed in the inner cavity of the smoke exhaust pipe 203. The smoke exhaust mechanism 3 includes a support rod 302, a filter plate 303, a fixed rod 308 and a support plate 309. The bottom of the support rod 302 is fixedly connected to the top of the smoke exhaust pipe 203. The surface of the filter plate 303 is fixedly connected to the top of the inner cavity of the smoke exhaust pipe 203. The surface of the fixed rod 308 is fixedly connected to the inner cavity of the smoke exhaust pipe 203. The surface of the support plate 309 is fixedly connected to the bottom of the inner cavity of the mounting seat 201. A fixed seat 304 is fixedly connected to one side of the fixed rod 308. A motor 305 is fixedly connected to the inner cavity of the fixed seat 304. The output end of the motor 305 is fixedly connected to a fan 306. A fan blade 307 is fixedly connected to the surface of the fan 306. Through the setting of the filter plate 303, it plays a filtering role in the interior of the smoke exhaust pipe 203, preventing foreign objects from the outside from entering the interior of the smoke exhaust pipe 203. Thus, through the setting of the motor 305, the fan blade 307 can be driven to rotate to extract the smoke in the room. And through the setting of the support plate 309, it prevents the parts inside the smoke exhaust pipe 203 from aging and falling off, and falling into the room to cause personal injury.

[0033] Refer to Figure 2 , the number of the support rods 302 is four and they are distributed in a ring around the smoke exhaust pipe 203. A smoke exhaust cap 301 is fixedly connected to the top of the support rod 302. The smoke exhaust cap 301 is integrally semicircular. Through the setting of the support rod 302, the position of the smoke exhaust cap 301 is supported. Thus, through the setting of the smoke exhaust cap 301, it plays a role in shielding and diverting the rainwater at the top of the smoke exhaust pipe 203, preventing the rainwater from entering the interior of the smoke exhaust pipe 203 and affecting the normal operation of the smoke exhaust pipe 203.

[0034] Working principle: When it is necessary to remove the smoke exhaust pipe 203 from the top of the base 1, first hold the handle 205 and rotate it. The rotation of the handle 205 drives the rotation of the smoke exhaust pipe 203. The rotation of the smoke exhaust pipe 203 drives the rotation of the connecting plate 202. The rotation of the connecting plate 202 drives the rotation of the positioning plate 206. During the rotation of the positioning plate 206, it will push the fixing plate 208 to contract inward until the fixing plate 208 is taken out from the inside of the fixing groove 207. Then, hold the handle 205 and move it upward. The movement of the handle 205 drives the movement of the smoke exhaust pipe 203 until the smoke exhaust pipe 203 is removed from the top of the base 1. When it is necessary to reinstall the smoke exhaust pipe 203 later, hold the handle 205 and move it downward. The movement of the handle 205 drives the movement of the smoke exhaust pipe 203. The movement of the smoke exhaust pipe 203 drives the movement of the connecting plate 202. The movement of the connecting plate 202 drives the movement of the positioning plate 206 until the positioning plate 206 is inserted into the inside of the positioning groove 209. And during the movement of the positioning plate 206, it will contact the surface of the fixing plate 208, so as to push the fixing plate 208 to contract inward through the movement of the positioning plate 206. When the positioning plate 206 completely enters the inside of the positioning groove 209, hold the handle 205 and rotate it. The rotation of the handle 205 drives the rotation of the smoke exhaust pipe 203. The rotation of the smoke exhaust pipe 203 drives the rotation of the connecting plate 202. The rotation of the connecting plate 202 drives the rotation of the positioning plate 206 until the fixing groove 207 and the fixing plate 208 are at the same horizontal position. When the surface of the fixing plate 208 is not blocked, the fixing plate 208 will be inserted into the inside of the fixing groove 207 under the push of the spring 214. And when the fixing plate 208 moves, it will slide on the surface of the guide rod 213, so as to guide the movement of the fixing plate 208 and prevent the position of the fixing plate 208 from shifting during the movement. When the fixing plate 208 moves to the specified position, the fixing plate 208 will stop moving under the action of the limiting plate 215 to prevent the fixing plate 208 from detaching from the surface of the guide rod 213. Then, the motor 305 can drive the fan 306 to rotate. The rotation of the fan 306 drives the rotation of the fan blades 307. The rotation of the fan blades 307 discharges the smoke in the room to the outside.
