[0024] 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.

[0025] Please see Figures 1-7This utility model provides a technical solution: an oil collection device for a fume hood exhaust port, comprising a fume hood body 1 and an exhaust port 2. The exhaust port 2 is provided at the top of the fume hood body 1, and an oil collection mechanism 3 is provided below the exhaust port 2. The oil collection mechanism 3 includes an extension seat 301, a positioning pin 302, an additional receiving plate 303, an oil receiving groove 304, a threaded pin 305, a guide pipe 306, a collection box 307, an oil outlet 308, a drain pipe 309, and a fixing seat 310. The system includes an iron fixing plate 311, a guide frame 312, a sealing plate 313, a first magnet 314, and a second magnet 315. Extension seats 301 are welded to both sides of the top inner wall of the smoke hood body 1. A positioning pin 302 is connected to the inside of the extension seat 301 through a limiting hole. An additional receiving plate 303 is connected to the bottom of the positioning pin 302. An oil receiving groove 304 is opened at the top of the additional receiving plate 303, and threaded pins 305 are threaded to both sides inside the additional receiving plate 303. A guide pipe 306 is connected to both sides of the bottom end of 303; a collection box 307 is connected to the bottom end of the guide pipe 306 via an extension strip, and an oil outlet hole 308 is opened in the middle of the bottom end of the collection box 307; a drain pipe 309 is connected to the side of the collection box 307 near the oil outlet hole 308, and a fixing seat 310 is welded to the middle of the outer wall of the collection box 307; an iron fixing plate 311 is slidably connected inside the fixing seat 310, and a guide frame 312 is welded to the top of the iron fixing plate 311; the guide frame The bottom of 312 is connected to a sealing plate 313, and the side of the collection box 307 near the fixed seat 310 is connected to a first magnet 314; the top of the outer wall of the fixed seat 310 is connected to a second magnet 315, and the guide frame 312 is L-shaped; the iron fixing plate 311 is magnetically connected to the first magnet 314, and the iron fixing plate 311 is magnetically connected to the second magnet 315; the extension seat 301 has a limit hole inside, and the guide tubes 306 are distributed in a figure-eight shape.

[0026] In practical implementation, during the use of the oil fume collection device at the exhaust port of the fume hood, in order to prevent the oil fumes from turning into oil droplets on the fume duct and falling into the fryer, the mounting plate 303 is moved in advance so that the positioning pin 302 at the top of the mounting plate 303 is connected to the extension seat 301. At this time, the positioning pin 302 and the extension seat 301 are engaged, thereby preventing the mounting plate 303 from rotating at will. Then, the threaded pin 305 is rotated to connect with the wall, thereby fixing the mounting plate 303 to prevent it from moving down. After that, when the oil fumes turn into oil droplets, they are first guided to the guide pipe 306 through the oil collection groove 304, and then the oil is guided to the collection box 307 through the guide pipe 306. Since the bottom of the collection box 307 is connected to the drain pipe 309, the oil can also be discharged to the sewer through the drain pipe 309.

[0027] When the user finds the drain tube 309 obstructing arm movement, they can manually push the iron fixing plate 311 to disengage from the second magnet 315, causing the iron fixing plate 311 to move the guide frame 312. Since the guide frame 312 is connected to the sealing plate 313, the movement of the guide frame 312 causes the sealing plate 313 to move together until the sealing plate 313 covers the oil outlet 308. At this time, the iron fixing plate 311 and the first magnet 314 are magnetically attracted to each other, thus preventing oil from flowing out of the oil outlet 308. After that, the drain tube 309 can be removed, so that the dripping oil will only be stored in the collection box 307. Then, it can be used flexibly according to the kitchen situation, thereby preventing oil drips into the oil pan and causing oil pollution. It can also prevent the hot oil from splashing onto people. Finally, when used in the oil collection device of the fume hood exhaust port, it plays a role in preventing oil drips and splashes.

[0028] See Figures 1-3 , Figure 5 and Figure 6 It is known that a limiting mechanism 4 is provided on the outside of the collection box 307, and the limiting mechanism 4 includes a support base 401, a limiting strip 402, a fixing pin 403, a limiting frame 404 and a fixing post 405. The bottom end of the collection box 307 is connected to the limiting strip 402 through a sliding groove; the bottom end of the limiting strip 402 is connected to the support base 401, and the top end of the support base 401 is welded to the main body 1 of the smoke collection hood; a fixing post 405 is welded to the middle of the outer wall of the support base 401, and the limiting frame 404 is slidably connected to the outer wall of the fixing post 405; a fixing pin 403 is welded to the bottom end of the limiting frame 404, and the support base 401 is in the shape of a "C"; the support base 401 and the limiting strip 402 form an integral structure, and a fixing hole is opened on the side of the collection box 307 near the limiting frame 404, and the fixing pin 403 is slidably connected to the support base 401.

[0029] In practical implementation, during the use of the oil fume collection device at the exhaust port of the fume hood, as the usage time increases, the collection box 307 becomes covered with dirt and needs cleaning. First, manually move the limiting bracket 404. Because the limiting bracket 404 is connected to the fixing pin 403, the movement of the limiting bracket 404 causes the fixing pin 403 to move as well. Furthermore, since the limiting bracket 404 and the fixing post 405 are slidably connected, the fixing post 405 guides the movement of the limiting bracket 404, thereby controlling the movement of the limiting bracket 404. The guide allows the limiting frame 404 to move smoothly until the fixing pin 403 disengages from the collection box 307, thereby releasing the limiting effect on the collection box 307. At this point, the collection box 307 can be moved along the limiting strip 402 and then removed from the support base 401 for cleaning. This eliminates the need to repeatedly turn multiple sets of bolts to remove the collection box 307 for cleaning, saving time and effort. This facilitates the cleaning of the collection box 307 when the oil fume collection device at the exhaust port of the fume hood is used.

[0030] After the collection box 307 is cleaned, first move the collection box 307 into the support base 401 along the limiting strip 402. At this time, the collection box 307 and the limiting strip 402 are engaged, thus limiting the collection box 307. Then push the limiting bracket 404 so that the fixing pin 403 engages with the collection box 307, thereby fixing the collection box 307 and installing it back into its original position.

[0031] In summary, when using this type of fume hood oil fume collection device, the fume hood body 1 is first installed in a designated position. Then, the fan is started to generate negative pressure, which draws the fumes from the cooking area into the fume hood body 1. After the fumes pass through the filtration system to remove oil mist and odors, they are discharged outdoors through the exhaust port 2 and the exhaust pipe. This is existing technology and will not be elaborated on here. The oil receiving mechanism 3 guides the oil to the collection box 307 or drains it into the sewer, thereby preventing oil drips into the oil pan and causing contamination of the frying oil. It also prevents the hot oil from splashing onto people. The limiting mechanism 4 releases the limit on the collection box 307, at which point the collection box 307 can be removed for cleaning. The collection box 307 can be removed for cleaning without repeatedly turning multiple sets of bolts. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
