This invention discloses a special consumable for a double-layer cat litter box and its preparation and usage method, relating to the field of pet cleaning products technology. The invention's upper layer of cat litter and lower layer of absorbent and deodorizing granules, through synergistic design of formula and process, form a complete pet excrement treatment system. The upper layer of cat litter is responsible for trapping and encapsulating feces and draining urine, while the lower layer of absorbent and deodorizing granules is responsible for absorbing and treating odors generated by urine and feces. The combined use of these two layers achieves a highly efficient usage mode with automatic urine seepage, direct feces removal, no need for stirring the upper layer, and regular replacement of the lower layer. This significantly simplifies daily maintenance procedures, reduces the labor intensity of pet ownership, and significantly improves the user experience for family pet cat owners.

This utility model discloses an anti-oxidation device for copper wire transmission. A fixed box is placed at the initial connection end of the traction mechanism, and the copper wire is then passed through the sealing colloid of the first and second openings. Antioxidant is poured into the solid box through a first liquid inlet pipe, continuously submerging the copper wire. The sealing colloid prevents significant liquid leakage during copper wire transmission. Once the antioxidant reaches a preset standard, the traction mechanism is activated, guiding the copper wire through the antioxidant in the solid box. The fixed box possesses high mechanical properties and rigidity, ensuring long-term use. This device solves the technical problem of existing plastic bottles being too soft, having poor mechanical properties, and easily damaged, leading to antioxidant leakage and affecting the anti-oxidation process of the copper wire.

This invention discloses an antibacterial smart sofa fabric with integrated temperature sensing and its control method, belonging to the field of temperature measurement technology. The invention includes the following: an antibacterial fabric base layer loaded with antibacterial particles, forming a double-layer structure and bonded together; a temperature sensing integrated module with a temperature sensor integrated between the fabric base layers; an intelligent control module with a microcontroller as its core, receiving data and outputting control commands; a power supply module including a battery and a wireless charging coil, featuring protection functions and low battery warnings; a human-machine interaction module with a display screen and physical buttons displaying core information; a data storage module using a storage chip to store relevant operational data; and an antibacterial enhancement and control module including atomization and airflow circulation units, automatically activating when antibacterial activity is insufficient. This invention provides stable and long-lasting antibacterial performance, maintaining a long-term antibacterial effect through a dynamic enhancement mechanism. Distributed sensing and environmental compensation design improve measurement reliability, and multimodal interaction is convenient, adapting to different usage scenarios.

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.
