[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 A smoke exhaust valve that is easy to clean includes a connecting component 1 for guiding the flow of smoke, a smoke exhaust component 2 for extracting smoke is provided in front of the connecting component 1, and a filter component 3 for adsorbing soot and being easy to disassemble and clean is provided in the middle of the connecting component 1.

[0017] In this embodiment: the connecting component 1 includes a base 101, a flue 103 is provided on the top of the base 101, an air inlet pipe 102 is connected to the top of the flue 103, a side plate 104 is bolted to one side of the flue 103, two limiting plates 105 are symmetrically arranged in the middle of the flue 103, and two fixing bolts 106 are slidably installed on the limiting plates 105. The flue 103 is vortex-shaped, and the air inlet pipe 102 is integrally formed with the flue 103. When it is necessary to discharge harmful smoke, the mounting bracket 203 supports the operation of the exhaust fan 202, and the smoke is drawn from the air inlet pipe 102 into the flue 103. The treated smoke is discharged from the middle of the flue 103 through the exhaust pipe 201. When it is necessary to thoroughly clean, the side plate 104 can be removed relatively easily to expose the flue 103 for cleaning. After maintenance, it can be reinstalled, which greatly reduces the difficulty of cleaning work.

[0018] In this embodiment: the smoke exhaust assembly 2 includes an exhaust pipe 201, an exhaust fan 202 is installed at the front end of the exhaust pipe 201, a mounting bracket 203 is provided in the middle of the exhaust fan 202, a connecting flange 204 is provided at the front end of the exhaust fan 202, the mounting bracket 203 is fixedly connected to the side plate 104, and the exhaust fan 202 is bolted to the mounting bracket 203.

[0019] In this embodiment: the filter assembly 3 includes a sliding frame 301, with adsorption nets 302 on both the upper and lower surfaces of the sliding frame 301. A filter media box 303 is slidably disposed in the middle of the sliding frame 301. Several air grids 304 are disposed on the bottom surface of the filter media box 303. Two partitions 305 are evenly disposed inside the filter media box 303. A handle 306 is disposed on one side of the filter media box 303. Two through holes 307 are opened on the side of the filter media box 303 and the sliding frame 301 near the handle 306. The sliding frame 301 is slidably connected to the flue 103. The sliding frame 301 and the filter media box 303 are fixedly connected to the limiting plate 105 by fixing bolts 106 passing through the through holes 307. Each time the flue gas flows through the flue 103, it passes through the adsorption net 302 once. The deeper the adsorption net 302 is, the finer it is. Through the graded filtration, it is prevented that the soot will accumulate too thickly and affect the flow. The activated carbon particles in the filter media box 303 adsorb sulfur dioxide and fine dust in the flue gas, avoiding corrosion of the internal components of the exhaust fan 202 and pollution caused by emissions into the atmosphere. After the flue gas is exhausted, the fixing bolts 106 are removed to separate the sliding frame 301 from the limiting plate 105. Then, the handle 306 is pulled to move the filter media box 303 out of the sliding frame 301. The adsorption net 302 is scraped and cleaned, and the activated carbon in the filter media box 303 is replaced to ensure the adsorption effect and extend the maintenance cycle of the flue 103 and the exhaust fan 202.

[0020] Working principle: When harmful fumes need to be discharged, the mounting bracket 203 supports the operation of the exhaust fan 202, drawing the fumes into the flue 103 through the inlet pipe 102. The sliding frame 301 supports the adsorption net 302 to block large particles of impurities. Each time the fumes flow through the flue 103, they pass through the adsorption net 302. The deeper the adsorption net 302, the finer it is. Through this graded filtration, excessive buildup of soot is prevented from affecting flow. The partition 305 isolates the filter media box 303 from the connection between it and adjacent flues 103, preventing the fumes from shifting. The activated carbon particles in the filter media box 303 adsorb sulfur dioxide and fine dust in the fumes, preventing corrosion of the exhaust fan 202. The internal components and emissions into the atmosphere cause pollution. The treated flue gas is discharged from the middle of the flue 103 through the exhaust pipe 201. After the flue gas is discharged, the fixing bolts 106 are removed to separate the sliding frame 301 from the limiting plate 105. Then, the handle 306 is pulled to move the filter media box 303 out of the sliding frame 301. The adsorption net 302 is scraped and cleaned. The activated carbon in the filter media box 303 is replaced to ensure the adsorption effect. This extends the maintenance cycle of the flue 103 and the exhaust fan 202. When a thorough cleaning is required, the side plate 104 can be removed relatively easily to expose the flue 103 for cleaning. After maintenance, it is reinstalled, which greatly reduces the difficulty of cleaning work.

[0021] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
