This invention relates to a multidimensional feedback-based interactive nebulizer inhalation system for children, comprising: a flow regulation component having a dosing state and an blocking state; a detection module for acquiring vital sign monitoring data; a feedback execution module including an interactive prompting unit and a drive unit; and a control module communicatively connected to the detection module and the feedback execution module. The control module is configured to execute the following processing flow: receiving vital sign monitoring data to assess airway safety risks and nebulization operation compliance respectively; when there is an abnormal airway safety risk, generating a collaborative intervention command: the command drive unit switches the flow regulation component to the blocking state and simultaneously controls the interactive prompting unit to output soothing interactive information; when there is no abnormal airway safety risk, controlling the interactive prompting unit to output interactive information for action correction or positive guidance based on the compliance assessment results.

The invention discloses a built-in fish tank filter structure. The built-in fish tank filter structure comprises a shell, a filtering module and a draining pump, the shell is provided with a filtering cavity and a dirt collecting tank, the dirt collecting tank is located on one side of the filtering cavity, one end of the dirt collecting tank penetrates through the shell and is provided with a water inlet, the other end of the dirt collecting tank is communicated with the filtering cavity, the filtering module is arranged in the filtering cavity, and the draining pump is located beside the filtering cavity and connected with the filtering cavity; thus, through the design of the sewage collecting tank, sewage of the fish tank firstly enters the sewage collecting tank and then flows into the filtering cavity from the other end of the sewage collecting tank, so that part of solid dirt in the sewage is intercepted and deposited in the sewage collecting tank, and the phenomenon that the dirt is scattered everywhere due to movement of a product when a user takes out the product subsequently is prevented; therefore, secondary pollution of water in the fish tank is avoided, the quality of water in the fish tank is guaranteed, time and labor are saved, the use requirements of users are met, and the application range is wide.

The application discloses a nickel-copper-nickel-nickel tungsten multilayer plating layer and a preparation method thereof. After pretreatment of a base material, a nickel bottom layer is obtained by first electroplating nickel, a copper layer is obtained by electroplating copper, a nickel intermediate layer is obtained by second electroplating nickel, a nickel tungsten alloy surface layer is obtained by electroplating a nickel tungsten alloy, and then heat treatment is performed to obtain the nickel-copper-nickel-nickel tungsten multilayer plating layer. When electroplating the nickel tungsten alloy, a titanium base-iridium tantalum oxide coating anode is used, and the electroplating solution for electroplating the nickel tungsten alloy is a citric acid system. In the titanium base-iridium tantalum oxide coating anode, the mass fraction of tantalum is more than 5% higher than the mass fraction of iridium. The corrosion resistance of the plating layer is greatly improved through the cooperation of the multilayer plating layer and the improvement of the quality of the outermost plating layer.
