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.

A vacuum-sealed storage cabinet includes an outer shell, an inner liner housed within the outer shell, and a sliding door that opens and closes on the front side of the inner liner. A vacuum device is located on the rear side of the outer shell for creating a vacuum inside the inner liner. The air inlet of the vacuum device is connected to the interior of the inner liner, and the air outlet is connected to the outside. A vent valve is located on the door; when the vent valve is open, the interior of the inner liner is connected to the outside. This storage cabinet, by using a vacuum device on the rear side of the outer shell with its air inlet connected to the interior of the inner liner and its air outlet connected to the outside, extracts air from the interior of the inner liner and discharges it outside the cabinet, creating a vacuum environment inside the inner liner. This inhibits oxidation, mold, or moisture absorption of items, allowing for long-term storage. Furthermore, the vent valve on the door, when opened, connects the interior of the inner liner to the outside, balancing the internal and external air pressures and allowing the door to be opened without resistance.

This invention discloses a method and system for digital human hosting programs using AI technology, relating to the field of artificial intelligence technology. The method includes: firstly, parsing the program schedule to extract key semantics, and dynamically calculating semantic temperature by combining the attention weight gradient change rate and action information entropy density; subsequently, in the action expression stage, using semantic temperature to inversely adjust the Brownian diffusion coefficient; and strictly limiting the random differential increment within redundant degrees of freedom using the Jacobi null space projection operator to ensure the accuracy of core action intentions while endowing posture with agility. A latent space similarity drift evolution mechanism controlled by semantic temperature is established, and the high-frequency action probability space after elimination and alignment is jointly superimposed and normalized for expansion; finally, using an accelerometer integral cost function to filter out mechanical twitches and perform interpolation stitching. This completely overcomes the technical pain point of monotonous digital human expression, generating humanoid actions that balance physical accuracy and extremely high diversity.
