The invention discloses an aluminum alloy door and window achieving hidden type trace water drainage and belongs to the field of aluminum alloy doors and windows. The aluminum alloy door and window achieving hidden type trace water drainage comprises an aluminum alloy door and window outer frame with a glass plate installed on the inner side. A hidden type water drainage groove is formed in the front end of the aluminum alloy door and window in a digging manner. A water absorbing frame is arranged in the hidden type water drainage groove. A sealing cover frame is connected to a groove openingof the hidden type water drainage groove. Multiple water guide holes are uniformly formed in the lower end of the aluminum alloy door and window outer frame in a digging manner. Embedded type water absorbing bars are fixedly connected into the water guide holes. Multiple side air drying holes are formed in the left inner side end and the right inner side end of the aluminum alloy door and window in a digging manner correspondingly. Upper air drying holes distributed uniformly are formed in the upper inner side end of the aluminum alloy door and window outer frame in a digging manner. Accordingto the aluminum alloy door and window, the multiple embedded type water absorbing bars are utilized for absorbing trace water spots on the surface of a sliding rail of the aluminum alloy door and window, the absorbed water is transferred and dried through the water absorbing frame, the surface of the sliding rail is effectively prevented from rusting, and flexibility of the door and window opening and closing is ensured.

The invention relates to an automated water quality cleaning and filtering technology for swimming pools, and discloses an omnibearing cleaning and filtering robot for a swimming pool. The cleaning and filtering efficiency of the robot is improved, and the energy consumption of the robot is lowered by optimizing the structure. According to the technical scheme, the omnibearing cleaning and filtering robot for the swimming pool comprises a shell, an electric water pump, a control module, a battery, a filterer, a multi-channel rotating switch, a water storage bin, an air storage tank, a solenoid valve, a water outlet, a steering blade, a steering engine, a water channel, a water surface water inlet and a water bottom water inlet. According to the omnibearing cleaning and filtering robot, the water volume of the water storage bin is controlled through compressed air in the air storage tank, and the robot can float on the water surface of the swimming pool or submerged into water to conduct water quality cleaning and filtering; the battery is adopted to supply power to the robot, cable connection is omitted, and the robot moves flexibly and freely; when the robot is on the water surface, the robot can conduct operation through a remote command or conduct operation according to internal programming.

The invention discloses a novel antibacterial and aromatic quilt and a manufacturing method thereof. In the preparation process, the blended yarn of polyester high-fiber, bamboo fiber and cupro ammonia fiber is used to weave the fabric, so that the fabric has good deodorizing and antibacterial, antibacterial and antibacterial properties. Thermal insulation performance, antistatic performance; microcapsule fragrance finishing agent is used to evenly distribute fragrance microcapsules on the surface of fabric fibers, and the fragrance coated in polymer capsules will be released slowly, thus greatly prolonging the fragrance retention time of fibers.

The invention discloses an underwater net washing disk, comprising an annular outer protective frame (14), a flange plate (4), a water slip ring (1), and a high-pressure conduit shaft (3). The bottom of the water slip ring (1) is rotatably provided radial manifold branches (10). The tail ends of the manifold branches (10) are provided with high-pressure nozzles (12) arranged in an inclined manner. The back surfaces of the manifold branches (10) are also provided with radial turn-out blades (9). The internal of the water slip ring (1) is provided with an axial center hole (2), and the hole is communicated with the high-pressure conduit shaft (3) and the manifold branches (10). Through rotation of the plurality of manifold branches and the blades, cleaning of a netting is realized, so as to reduce structural weight and increase simplicity of manufacturing and installation. Components are modularized, and component changing and maintenance are easy. In addition, the turn-out blades are arranged along the radial direction of the manifold branches, and the turn-out blades have large water absorption area, so as to reduce pressure loss and improve cleaning capability.

The invention relates to the technical field of leather, which discloses a preparation process of a high-physical cowhide leather base cloth, including a batching process, a chemical fiber netting process, a kraft fiber netting process, a chemical fiber net and a kraft fiber net. Web process; in the batching process, chemical fiber and kraft fiber are batched according to the weight ratio of 1:0.8 to 1:1.2; the chemical fiber web forming process includes opening, carding, web laying, pre-wetting, pre-wetting The process of thorning: in the kraft fiber net forming process, the kraft fiber raw material is made into a kraft fiber net by air-laid or water-flow-laid net; The process of spunlace, vacuum drying, and drying; wherein, the chemical fiber is a mixed fiber of polyester fiber and nylon fiber, and the nylon fiber in the mixed fiber accounts for more than 80% of the total weight of the mixed fiber. The invention improves the physical performance of the cow fiber leather base cloth and reduces the production cost.
