5results about How to "Guaranteed suction effect" patented technology

The invention discloses a multi-source data fusion-based air volume dynamic adjustment method of a fume hood for a clean environment, particularly relates to the technical field of clean environment control, and aims at solving the problem that air volume adjustment of an existing fume hood cannot give consideration to front air suction safety, pressure difference stability and overall energy conservation. A basic operation data set is formed by collecting and filtering window opening and cabinet air speed, an air volume demand value and an initial priority parameter are calculated according to the data set and a room use state mark to form a demand data set, and a deviation memory parameter and a fluctuation influence parameter are calculated by fusing room pressure difference data and the availability of an exhaust fan. Obtaining a stable control priority adjustment coefficient through a time decay score learning model, correcting the priority, distributing the target exhaust air rate and the exhaust fan output, forming a target distribution result, comparing the target distribution result with the actual air valve opening degree and the exhaust fan output state, calculating the adjustment amount, and issuing a control instruction according to the priority; and the deviation record feedback updating coefficient and the demand value are verified in the control period to realize self-adaptive adjustment.

The embodiment of the invention discloses an aerosol generating substrate section, a preparation method thereof and an aerosol generating product, the aerosol generating substrate section comprises a flaky substrate, the aerosol generating substrate section is of a winding structure formed by winding the flaky substrate, and the flaky substrate comprises a substrate layer, a casting layer and a plurality of substrate strips; the substrate strips are arranged on one side of the substrate layer at intervals in the winding direction of the flaky substrate, the axial directions of the substrate strips intersect with the winding direction, and the substrate strips can be heated to generate aerosol; the curtain coating layer is formed by curtain coating slurry in a curtain coating mode, and the curtain coating layer wraps at least part of the outer side wall of the matrix strip. The airflow channels can be formed between the substrate strips, and the generated aerosol can be released through the airflow channels, so that the suction effect of the aerosol generating product is ensured, and the suction resistance of the aerosol generating product is reduced.
