According to the data from the Tianyancha App, Jiangsu Baoli Jie Environmental Technology Co., Ltd. (920802) recently obtained a new utility model patent authorization. The patent is titled "Wet Film-forming Structure and a Wet Fireproof Smoke Hood Integrated Machine with the Same", with the patent application number being CN202520438365.6, and the authorization date being January 13, 2026.

The patent abstract indicates that this utility model discloses a wet film-forming structure and a wet fireproof smoke hood integrated machine equipped with it. It comprises a perforated plate assembly and a water circulation device for delivering water to the perforated plate assembly. The perforated plate assembly includes a lower perforated plate and an upper perforated plate. The cooking fumes pass through the lower perforated plate and the upper perforated plate in sequence. The water circulation device continuously delivers water to the lower perforated plate and forms a water film on it. The thickness of the water film is set at 8 to 12 millimeters, and the flow velocity of the cooking fumes passing through the lower perforated plate is 8 to 12 meters per second. This technology enables the cooking fumes to come into contact with the water film on the lower perforated plate for cooling, filtering, and saturation. Then, the saturated cooking fumes gas comes into contact with the upper perforated plate for cooling and water removal. By setting the upper and lower perforated plates, the smoke purification effect is improved. At the same time, the water circulation device continuously delivers water to form a water film, ensuring that the cooking fumes are always in contact with water, achieving efficient cleaning and cooling.

As a company deeply engaged in the field of oil fume purification, Baoli Jie has continuously invested in technological research and development. Based on the company's financial data from the 2025 mid-year report, in the first half of 2025, the company spent 505.15 million yuan on research and development. As of now, Baoli Jie has made external investments in 20 enterprises, participated in 65 bidding projects, and possesses 60 trademark information, 271 patent information, and 60 copyright information.

Industry insiders point out that as the standards for restaurant cooking fume emissions become increasingly strict, integrated smoke hoods with high purification capabilities are becoming a must-have in the market. The wet-type fire-resistant integrated smoke hood patent obtained by Baoli Jie this time not only enhances the purification efficiency but also takes into account fire safety, and is expected to provide a new technical solution for the management of cooking fumes in commercial kitchens.
