The application provides a sample flow cell for nanoparticle detection in liquid medium, and belongs to the technical field of particle detection. The technical problems of unstable flow field, serious stray light interference, inability to monitor the internal flow state in situ, and difficult processing of complex structure of the existing sample flow cell are solved. The pool body is provided with a main flow channel, a detection section located in the middle, and a flow focusing structure composed of a tapered section and an expanding section, which improves the detection efficiency while maintaining the stability of the flow state; the side wall of the detection section is provided with a bonded light window and a light diaphragm, and the outside of the light diaphragm is provided with an auxiliary flow channel; the pool body is also provided with a detection interface for connecting a pressure difference sensor. The flow field of the detection area is optimized through the flow focusing structure, the stray light is effectively absorbed by the black glass diaphragm, and the in-situ monitoring of the internal flow and the flow health state is realized through the pressure difference detection. The overall structure is suitable for injection molding, and has the advantages of high detection performance, strong reliability and low manufacturing cost.

This application relates to the field of surface mount inductor processing technology, and discloses a surface mount inductor winding machine welding device, including: a welding device body, a shielding and protection component, a rotating disassembly component, and a transparent glass. The welding device body includes a welding box and a placement platform disposed in the center of the welding box. The shielding and protection component is disposed on both sides of the outside of the welding box. This utility model, by incorporating the shielding and protection component, the rotating disassembly component, and the transparent glass, allows the transparent glass to weaken the generated strong light, thereby enabling personnel to observe the welding status inside the equipment from the outside. Because laser welding generates high temperatures that degrade the quality of the transparent glass, the rotating disassembly component allows for rapid replacement of the transparent glass without the aid of external tools. Furthermore, the shielding and protection component can block the observation hole, allowing the operation inside the welding box to be completed without shutting down during the replacement of the transparent glass.

This invention discloses a method for preparing a cobalt-free black glaze for heat-resistant cookware and its decorative product. The method includes the following steps: First, raw materials are weighed according to the following mass percentages: cuprous oxide 21-39%, alumina 13-29%, silicon dioxide 32-65%, iron oxide 0.6-3.0%, and manganese oxide 0.3-2.0%. After being mixed evenly, the mixture is placed in a crucible and melted at high temperature. The melt is then water-quenched to obtain a black glass frit. Next, the black glass frit is dried, pulverized, and sieved to obtain black glass powder. Then, the black glass powder is mixed with water at a mass percentage of 100%:50-65%, and kaolin and a suspending agent or dispersant are added. The mixture is ball-milled evenly to prepare the glaze. The glaze obtained in step three is applied to the surface of a bisque-fired spodumene-based heat-resistant cookware blank. After drying, it is fired at 1210-1260℃ for 0.5-3 hours to obtain a black glaze layer. This invention has a simple process, low cost, and can be mass-produced, with broad application prospects.
