The invention discloses a knowledge question-answering method and system based on a large language model and a semantic abstract. The system comprises a tree structure abstract generation subsystem which comprises a knowledge base configuration module, a file management module, a document analysis module and a knowledge block management module and is used for automatically generating tree structure hierarchical knowledge blocks for large manual documents or multi-chapter manual documents; the dual-channel retrieval engine subsystem comprises a question rewriting module, a semantic abstract retrieval module, a detail knowledge block retrieval module, a father-son retrieval module and a prompt word construction module, and all the modules work cooperatively to ensure that semantic abstract knowledge blocks and detail knowledge blocks related to the question of the user are retrieved. According to the method, by introducing the semantic abstract based on the tree structure and the two-channel retrieval, perception of global knowledge and accurate extraction of local fine-grained knowledge can be achieved at the same time, and then the ability of a knowledge base question-answering system in processing the general and inductive problems is improved.

The utility model relates to a bottle cap assembly and a container, the bottle cap assembly comprises an inner plug piece, an inner cap piece, an inner sleeve piece and an outer piece, the inner plug piece is arranged on a first liquid flow opening of the inner sleeve piece, the inner cap piece is plugged on a second liquid flow opening of the inner sleeve piece, the inner sleeve piece comprises a first inner sleeve and a second inner sleeve which are made of different materials, and the outer piece is arranged in the first inner sleeve; the second inner sleeve is arranged on the peripheral face of the first inner sleeve in a surrounding mode, and the outer part is arranged on the inner cover part and the second inner sleeve in a sleeving mode and attached to the peripheral face of the second inner sleeve. According to the bottle cap assembly and the container, the first inner sleeve and the second inner sleeve are made of different materials, so that the first inner sleeve connected with the inner plug piece and the inner cap piece can be made of materials which do not affect contact with liquid, and the safety requirement is met; and the second inner sleeve connected with the outer part can be made of a material which is excellent in temperature resistance and impact resistance and is prohibited from being in contact with liquid, so that the inner sleeve part is not easy to pull out, and the bottle body or the outer part can be damaged when the inner sleeve part is forcibly pulled out, and the aim of preventing counterfeiting is fulfilled.

According to the bent pipe rotating structure of the shaver, a shaver head comprises a shell and a cutter head assembly, the bent pipe rotating structure comprises a bent pipe, a spring, a first connector and a second connector, the spring, the first connector and the second connector are arranged in the bent pipe, the front end of the bent pipe is connected with the rear end of the shell, and the rear end of the bent pipe is connected with a shaver body through a base. The spring is a spiral spring made of a special high-performance steel wire, one end of the first connector is connected with the rear end of the spring, the other end of the first connector is connected with the steel shaft, the steel shaft is connected with the shaft core in the base, one end of the second connector is connected with the front end of the spring, and the other end of the second connector is connected with the rotating shaft. The rotating shaft is in transmission connection with a cutter head of the cutter head assembly through a gear. The shaver is simple and reasonable in structure and convenient to assemble, motor power is transmitted to the head structure of the bent pipe through a spring structure by adopting spring connection to drive the shaver head to move, the problem that the head appearance of a traditional shaver is limited by a transmission mechanism is solved, transmission is stable and reliable, and meanwhile the head appearance is diversified.

This application relates to the field of pipe fitting inspection technology, and in particular to an automated visual inspection device for pipe fitting production lines. The device includes a frame with a base plate on one side. A sliding plate is slidably mounted on the base plate, and a clamping component is mounted on the sliding plate on one side. Multiple evenly distributed uprights are arranged on the frame, with one upright on one side mounted on the sliding plate. Clamping components are mounted on each of the uprights. Each clamping component includes a support plate mounted on an upright, with a V-shaped groove on the support plate. A connecting frame, L-shaped in shape, is mounted on one side of the support plate, and a guide rod passes through the connecting frame. The guide rod is located on a pressure plate directly above the support plate. The device uses a downward-pressing cylinder to push the pressure plate downward, forming an annular clamping space between the V-shaped pressure groove and the V-shaped support groove. The self-centering effect of the V-shaped surface ensures the position of the pipe fitting axis. The coordinated force from multiple clamping points evenly distributes the weight of the pipe fitting to each support point, effectively suppressing bending deformation of long pipe fittings.

This invention provides a high-pressure heating device for water purifiers, comprising a sealed tank, an inlet pipe, an outlet pipe, a heating element, a baffle plate, a temperature sensor, a level switch, and a vent pipe. By combining a sealed high-pressure heating method with a buffer cavity design, it solves the problem of insufficient boiling point in traditional water purifiers due to altitude and pressure limitations, raising the boiling point of water to 100℃ or higher, achieving true boiling at high temperatures. The cavity above the tank absorbs the volume of liquid expansion, reducing long-term pressure and improving sealing reliability. Multi-point monitoring and intelligent control ensure precise regulation of water temperature, level, and pressure, providing users with instant boiling water and enhancing the user experience. This invention has a reasonable structure, is safe and reliable, and is suitable for various water purifier products.

The application provides a height-adjustable ceiling structure, which comprises a support, a rotating rod, a keel and a clamping column, the support is provided with a rotating hole, the rotating rod is rotationally connected with the rotating hole, a plurality of clamping holes are formed in the rotating rod and are arranged around the rotating shaft of the rotating rod. The keel is provided with a lifting rope, one end of the lifting rope is arranged on the rotating rod, the other end of the lifting rope is arranged on the keel, and the lifting rope is wound on the rotating rod. The height-adjustable ceiling structure provided above is wound on the rotating rod through the rotation of the rotating rod, the lifting rope drives the keel to ascend or descend, the clamping column is clamped into the clamping hole to limit the rotation of the rotating rod, the keel is fixed at a specified height, the height of the ceiling structure is adjusted, and the inconvenience and limitation caused by the existing fixed-height ceiling structure can be effectively solved.
