[0002] Kitchen fumes are not uncommon in our daily lives. As long as it involves daily life, eating, and cooking, it is bound to be related to fumes. Daily frying and deep-frying will produce a lot of fumes. Although there are fume purifiers to help humans extract and purify fumes and reduce the harm caused by kitchen fumes, it is undeniable that the harm of fumes has always existed. The PM2.5 and various harmful substances contained in it have a great impact on the respiratory system in a high temperature environment and can increase the risk of cancer.

[0003] As people pay more and more attention to health, centralized oil fume emission devices have emerged. People use centralized oil fume emission devices to collect and discharge oil fume while eating.

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0027] As attached Figure 1 As shown, the oil fume centralized emission device to be protected by the utility model has an oil fume centralized emission device body 1, wherein the oil fume centralized emission device body 1 includes an oil fume collecting part 4 for collecting oil, an oil fume concentrating part 3 located on the oil fume collecting part 4 and concentrating the collected oil fume, and an oil fume emission part 2 located on the oil fume concentrating part 3 and discharging the concentrated oil fume, wherein an oil fume collecting port 41 for inhaling oil fume is provided on the lower surface of the oil fume collecting part 4, an exhaust port 13 is provided on the upper surface of the oil fume emission part 2, and an oil fume channel 8 is provided inside the oil fume concentrating part 3. After the oil fume is inhaled into the oil fume collecting port 41, it enters the oil fume duct 26 and is discharged through the exhaust port 13 after being transmitted through the exhaust port 8.

[0028] The aforementioned oil fume concentrating portion 3 is rectangular, and a fixed chamber 5 for installing an oil fume conveying structure is formed in the oil fume concentrating portion 3. The back of the oil fume concentrating portion 3 has an opening, and an internal frame 6 is coupled to the fixed chamber 5 through a protruding portion 7. The aforementioned internal frame 6 includes a lower plate, a middle plate and an upper plate. The two ends of the lower plate, the middle plate and the upper plate are connected. Except for the interconnected positions, the lower plate, the middle plate and the upper plate are separated from each other.

[0029] Circular holes are respectively arranged at each upper plate, middle plate and the connecting position of the upper plate. After the circular opening passes through the connecting position from top to bottom, a smoke exhaust channel 8 is formed. A smoke collecting and discharging structure is installed in the smoke exhaust channel 8. The separated parts of the upper plate, middle plate and lower plate form an installation chamber 10 that can accommodate the driving motor 9. A driving gear 11 is connected to the rotating shaft end of the driving motor 9. The driving gear 11 is directly engaged with the oil fume collecting and discharging structure on one side, and the driving gear 11 and the oil fume adsorption and discharging structure on the other side are indirectly engaged through a transmission gear. When the driving motor 9 drives the driving gear 11 to rotate, the driving gear 11 drives the oil fume collecting and discharging structures on both sides thereof to rotate simultaneously.

[0030] Combination Figure 3 and Figure 4The above-mentioned oil fume collection and emission structure includes a connecting column 12 vertically arranged in the smoke exhaust channel 8, which is coupled to the inner wall of the smoke exhaust channel 8 and the outer wall of a bearing. The connecting column 12 is arranged in the bearing. The connecting column 12 has two ends, wherein the end of the connecting column 12 close to the oil fume collection part 4 is the bottom end, and the end of the connecting column 12 close to the oil fume emission part 2 is the top end. A negative pressure fan is arranged at the bottom end of the connecting column 12, and the negative pressure fan and the negative pressure fan blades 123 are drivingly connected. The top shaft of the connecting column 12 is connected to the smoke exhaust fan blades 122; a driven gear 121 for directly or indirectly engaging with the driving gear 11 is arranged in the middle part of the connecting column 12 and above the bearing.

[0031] When in use, the user connects the device to an external control power supply. After the device is powered on, the shaft end of the drive motor 9 starts to rotate, and the driving gear 11 connected to the shaft end of the drive motor 9 starts to rotate. One side of the driving gear 11 directly engages with the driven gear 121 located on the connecting column 12, and the other side of the driving gear 11 engages with the driven gear 121 on the other connecting column 12 through the transmission gear. At this time, one drive motor 9 drives the two connecting columns 12 to start rotating. At this time, the rotation directions of the two connecting columns 12 are consistent, and the connecting columns 12 installed on the connecting column 12 are connected to the connecting column 12. The negative pressure fan at the bottom of the connecting column 12 starts to work, and the user determines the working intensity of the negative pressure fan through an external button, driving the negative pressure fan blades 123 to reverse, generating suction at the position of the oil fume discharge part 2 close to the oil fume collecting part 4, and the smoke outside the device is sucked into the smoke exhaust channel 8 through the oil fume collecting port 41, and the smoke moves toward the smoke exhaust fan 122 in the smoke exhaust channel 8. Driven by the connecting column 12, the smoke exhaust fan 122 rotates and generates positive pressure, sending the wind in the smoke exhaust channel 8 into the oil fume discharge part 2, and finally discharged through the smoke exhaust port 13.

[0032] Combination Figure 2 In order to improve the efficiency of oil smoke entering the oil smoke discharge part 2 through the smoke exhaust channel 8, an open concentration box 21 is arranged at the contact position between the oil smoke exhaust part 2 and the oil smoke concentration part 3. The bottom end of the open concentration box 21 is open, and the bottom end of the open concentration box 21 fits the inner wall of the oil smoke concentration part 3. An internal cavity 23 is formed in the open concentration box 21. A connecting pipe 24 is respectively arranged in the internal cavity 23 and corresponding to the position of each smoke exhaust channel 8. A rotatable adjusting plate 25 is connected to the upper axis of each connecting pipe 24, and a smoke exhaust connecting port 22 for connecting to the smoke exhaust port 13 is arranged at the top of the open concentration box 21.

[0033] During use, the oil smoke enters the connecting pipe 24 in the open central box 21 through the smoke exhaust channel 8. The adjustment plate 25 installed on the surface of the connecting pipe 24 rotates on the surface of the connecting pipe 24 due to the upward thrust of the oil smoke, forming an opening. After the oil smoke enters the smoke exhaust connecting port 22 through the opening, it is discharged through the smoke exhaust port 13.

[0034] Combination Figure 5 In order to facilitate the maintenance of the device, an inspection port is set at the rear end of the oil fume exhaust part 2, and the inspection port is connected to the rear cover plate 1a by fixing studs 1b to achieve a sealable connection with the inspection port.

[0035] The smoke exhaust port 13 can be connected to an external smoke exhaust channel to achieve directional smoke exhaust.

[0036] Combination Figure 6 In order to filter the oil in the fume and prevent the pipeline from being blocked by excessive oil components in the fume, a filter 42 is installed at the fume collection port 41 to simply intercept the oil in the fume.
