During this process, the UV light bar 16 inside the hood shell 1 emits ultraviolet rays to decompose the fumes. At the same time, the external air connected to the fresh air pipe 6 enters the hood shell 1 through the fresh air pipe 6, and then the fresh air is ejected from the air curtain nozzle 5 to achieve the purpose of internal and external air exchange.

[0032] Embodiment 2

[0033] See also Figure 2-Figure 4In order to solve the problem that the device is inconvenient to clean internally during long-term use, the present embodiment provides the following technical solutions, a flushing mechanism is provided, and a cleaning liquid is sprayed out by the flushing mechanism to achieve the purpose of automatically cleaning the inside of the device, and specifically discloses: a filter plate 8 with an inclined structure is fixedly installed inside the smoke hood shell 1, and a UV light bar 16 fixedly installed inside the smoke hood shell 1 is provided behind the filter plate 8, a collecting tank 9 installed inside the smoke hood shell 1 is provided below the filter plate 8, and a flushing mechanism is installed on the front side of the smoke hood shell 1, and the outer surface of the filter plate 8 is automatically flushed by the flushing mechanism, and the flushing mechanism includes a flushing nozzle 11 fixedly installed at the upper end of the smoke hood shell 1, and the flushing nozzle 11 is fixedly installed at the upper end of the smoke hood shell 1. The position of 11 corresponds to the position of the filter plate 8, and guide strips 10 are installed at equal intervals on the lower surface of the filter plate 8. The flushing nozzle 11 forms a connecting structure with the storage box 12 through a delivery pipe 15 fixedly installed therewith, and the storage box 12 is fixedly installed with the inner side of an internal partition 7, and the storage box 12 stores cleaning liquid inside, and a transversely arranged sealing plate 1201 is slidably installed inside the storage box 12, and a return spring 1202 is fixedly installed between the upper surface of the sealing plate 1201 and the top of the storage box 12, and the storage box 12 forms a connecting structure with the fresh air duct 6 through a diverter pipe 13 fixedly installed at its upper end, and an electric-controlled valve 14 is installed at the connection between the diverter pipe 13 and the fresh air duct 6.

[0034] After the oil smoke enters the hood shell 1, it is first preliminarily filtered by the filter plate 8. After a period of use, the electric control valve 14 is opened. At this time, part of the air in the fresh air duct 6 enters the storage box 12 through the diversion pipe 13 (the cleaning liquid is injected into the storage box 12). The added air increases the air pressure inside the storage box 12, and the sealing plate 1201 inside the storage box 12 is pushed downward by the air pressure. Under the squeezing action of the sealing plate 1201, the cleaning liquid stored in the storage box 12 is sprayed out from the flushing nozzle 11 through the delivery pipe 15, and finally the cleaning liquid is sprayed onto the lower surface of the filter plate 8, thereby achieving the purpose of automatic cleaning.
