[0037] Please refer to again Figure 2-4, the main body 1 of the range hood includes a range hood housing 11. On the left and right sides of the inner wall of the range hood housing 11, air gathering ports 12 are respectively fixedly connected. At the top of the inner walls of the two air gathering ports 12, air extraction ports 13 are fixedly connected. Each of the two air extraction ports 13 includes an air extraction port main body 131. At the right side of the bottom of each of the two air extraction port main bodies 131, a motor placement bin 132 is fixedly connected. Inside the inner wall of the motor placement bin 132, a dual-axis motor 133 is fixedly connected. At the front and rear output ends of the dual-axis motor 133, conical gears 134 are respectively fixedly connected. On the side of each of the two conical gears 134 away from the dual-axis motor 133, a second conical gear 135 is meshed.

The left ends of the two wind direction plate lead screws 136 both extend into the inner wall of the air extraction port main body 131 and are movably connected to the left side of the inner wall of the air extraction port main body 131. On the outer walls of the two wind direction plate lead screws 136, a number of transmission blocks 137 are threadedly connected.

[0038] When the present utility model is in use: First, through the air extraction cover 2 and the air extraction pipe 3 on the main body 1 of the range hood, oil fumes can be inhaled into the main body 1 of the range hood. When the oil fumes enter the main body 1 of the range hood, through the two air gathering ports 12 inside the main body 1 of the range hood, the oil fumes can be preliminarily gathered and sent into the air extraction port 13. Through the dual-axis motor 133 inside the air extraction port 13, the conical gear 134 can be driven to rotate, and then the second conical gear 135 and the wind direction plate lead screw 136 can be driven to rotate.

When it is necessary to increase the smoke gathering area, the wind direction plate 1311 is driven by the dual-axis motor 133 to flip open, so as to increase the smoke gathering area and improve the adsorption efficiency of the oil fumes. When the oil fumes are less, the smoke gathering area can be reduced, the diffusion of the oil fumes can be reduced, and the filtering effect of the oil fumes can be improved.

Swing rods 3314 are respectively rotatably connected to left and right sides of the inner wall of the storage box housing 3311. Swing rod elliptical chutes 3316 are formed in inner walls of the two swing rods 3314. Bottom rods 3317 are fixedly connected to bottoms of the two swing rods 3314. Bottom sides of one sides of bottoms of the two bottom rods 3317 are aligned with the storage box chutes 3312. A spring 3322 is fixedly connected to a rear side of the inner wall of the storage box housing 3311. Slide rods 3324 are slidably connected to inner walls of the two vertical chutes 3313. A baffle 3323 is fixedly connected to an outer wall of the slide rod 3324. Baffle transmission blocks 3325 are respectively fixedly connected to bottom portions of left and right sides of the baffle 3323. Outer walls of the two baffle transmission blocks 3325 are slidably connected to inner walls of the storage box chutes 3312. Opposite surfaces of the two baffle transmission blocks 3325 extend to outer walls of the storage box housing 3311 through the storage box chutes 3312. Transmission plates 3318 are respectively fixedly connected to left and right sides of the storage box housing 3311. Motor placement blocks 3319 are respectively fixedly connected to rear sides of the two transmission plates 3318. Motors 3320 are respectively fixedly connected to inner walls of the two motor placement blocks 3319. Output ends of the two motors 3320 extend to inner walls of the transmission plates 3318 and are respectively fixedly connected to lead screws 3321. Front ends of the two lead screws 3321 are movably connected to front sides of inner walls of the transmission plates 3318. Outer walls of the two lead screws 3321 are respectively threadedly connected to inner walls of one sides of the two baffle transmission blocks 3325 extending to outer walls of the storage box housing 3311. The storage bin 333 includes a storage bin housing 3331. Two storage bin slide rods 3332 are respectively fixedly connected to rear sides of left and right sides of the two storage bin housings 3331. A rear side of the storage bin housing 3331 is fixedly connected to a front end of the spring 3322. Outer walls of two groups of the storage bin slide rods 3332 are slidably connected to inner walls of the second chutes 3315. Outer walls of two of the storage bin slide rods 3332 are slidably connected to inner walls of the swing rod elliptical chutes 3316 formed in the swing rods 3314.

[0040] When the utility model is in use: First of all, the fume enters the interior of the range hood through the outer shell 31 of the exhaust pipe. During the process of the fume entering the outer shell 31 of the exhaust pipe, the oil residue separation pipe 32 conducts preliminary oil residue separation on the fume, separating some oil droplets, and these separated oil droplets then fall into the oil collection box 33 located at the bottom of the outer shell 31 of the exhaust pipe;

[0041] The design of the oil collection box 33 makes clever use of the mechanical transmission principle. When the oil droplets accumulate to a certain extent, the motor 3320 starts to work, driving the baffle transmission block 3325 to move along the storage box chute 3312 through the lead screw 3321. As the baffle transmission block 3325 moves, the baffle 3323 and the slide rod 3324 slide in the vertical chute 3313, causing the baffle 3323 to gradually approach the storage bin 333. During this process, the spring 3322 is gradually compressed, providing power for subsequent reset;

[0042] When the baffle 3323 moves to a certain position, it will push the storage bin 333 forward. Due to the cooperation of the storage bin slide rod 3332 with the second chute 3315 and the swing rod elliptical chute 3316, while the storage bin 333 moves forward, it will also be guided by the swing rod 3314 to achieve a certain angle of swing. In this way, the storage bin 333 can smoothly slide out of the storage box main body 331, facilitating the user to clean the accumulated oil droplets.

[0043] After the cleaning is completed, the motor 3320 rotates in reverse, and the lead screw 3321 drives the baffle transmission block 3325 and the baffle 3323 back to the initial position. Under the elastic force of the spring 3322, the storage bin 333 also automatically resets, preparing for the next oil droplet collection;

[0044] Such a design not only improves the filtering effect of the range hood but also facilitates the user to clean the oil droplets. At the same time, the automatic entry and exit of the storage bin are realized through mechanical transmission, improving the intelligence level of the range hood and enhancing the user experience.

[0045] The above shows and describes the basic principles, main features, and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the utility model.
