Abstract: An air-permeable sponge composition and a method for preparing an air-permeable sponge by using the same belong to the field of articles for daily use. An air-permeable sponge composition includes a sponge body and an air-permeable coating, and an outer surface layer of the sponge body being coated with the air-permeable coating. A method for making the air-permeable sponge utilizes the composition of the air-permeable sponge, wherein the air-permeable sponge is made from the air-permeable sponge composition under specific process parameters. The sponge body and air-permeable coating have the same or similar contents of isocyanate, polyether polyol and polymeric polyol and a similar porous structure.

Abstract: The invention relates to a sleep support system and the control method thereof. People may come across such emergencies as insomnia for some reason when going to sleep or apnea during sleep for some reason. The invention comprises a bedding, a processor, a sleep aid mechanism, a data acquisition mechanism and a wake-up mechanism, wherein the data acquisition mechanism comprises a data converter, a vibration sensor assembly and a snore sensor which are connected to the data converter; the processor receives signals of the vibration sensor assembly through the data converter and controls the sleep aid mechanism; and the processor receives signals of the snore sensor through the data converter and controls the wake-up mechanism.

Abstract: A spiral air pressure spring designed by the invention solves the technical problems of complex structure and low compressive strength in the current gas springs. The spiral air pressure spring comprises a spring body, and is characterized in that the spring body is formed by an air column having a pressure air containing cavity, the air column is spiral, and at least one vent hole communicated with the containing cavity is arranged on the air column.

Abstract: An elasticity-adjustable air pressure spring designed by the invention solves the technical problems of complex structure and top-to-bottom air impenetrability in the current gas springs. The elasticity-adjustable air pressure spring comprises a spring body, and is characterized in that the spring body is formed by at least one hollow cavity column of a double-layer sidewall structure, a closed cavity containing pressure air is formed between the double layers of the sidewall, the cavity column is corrugated, and at least one vent hole communicated with the cavity is arranged on the sidewall of the cavity column.

Abstract: The invention relates to a diameter-variable cylindrical air pressure spring. The current air pressure spring has the shortcomings of complex structure, insufficient deformation stroke and poor ventilation effect.
