  • Publication number: 20230110094
    Abstract: Described herein is a method of using hollow fiber filter cartridge. The method includes: providing a hollow fiber filter cartridge inside or outside an environmental cleaning equipment; allowing a wastewater to enter the hollow fiber filter cartridge from an outside of the hollow fiber filter under no water pressure or low water pressure (such as under 30 gw/cm2); allowing the wastewater to cross a plurality of nanopores of the hollow fiber filter cartridge under no water pressure or low water pressure (such as under 30 gw/cm2) to produce a clean water; and allowing the environmental cleaning equipment to filter wastewater to produce clean water continuously, thereby improving cleaning efficiency and reducing water consumption.

  • Publication number: 20190300223
    Abstract: The present invention provides a telescopic storage can structure, which comprises a can, a hood and a cover. The can is disposed with an airtight member at an opening, and the hood is covered on the can and formed with an upper opening. The cover is disposed on the upper opening and formed with an air outlet and disposed with an air outlet valve assembly. The hood can be upwardly and downwardly displaced on the can according to a holding capacity, and when the hood is displaced downwardly, the cover will squeeze the internal air thereof and the internal air is sent out through the air outlet. Thereby achieving an effect of being able to adjust a size according to a holding capacity and facilitate an airtight purpose, and further, relative positions of the can and the hood can be telescopically adjusted according to a storage capacity.

  • Publication number: 20170217126
    Abstract: A foam structure is provided. The foam structure includes a plurality of resilient elements and a plurality of flexible connecting elements connected between the resilient elements. The resilient element comprises an upper material layer, a lower foam material layer, and an intermediate material layer. Two adjoining intermediate material layer are connected with each other through at least one connecting element provided therebetween, but an interspace is also provided therebetween. The resilient elements and flexible connecting elements may be integrally formed by integral molding with a foam material as a one-piece foam structure.

  • Publication number: 20140186577
    Abstract: A breathable elastic buffer material structure includes two breathable fabrics, a plurality of spaced elastic pillars between the two breathable fabrics and an elastic plate between the two breathable fabrics. The elastic plate has a plurality of spaced through holes and ribs between the through holes. The elastic pillars are inserted through the through holes, respectively. The ribs of the elastic plate are located between the elastic pillars. When the elastic pillars are applied with an impact force, the ribs not only provide an elastic buffer effect itself but also bear the impact force so the elastic pillars won't slant to enhance the buffer effect. In case a rod-like object penetrates between the elastic pillars, the ribs can block the rod-like object. The present invention provides better buffer and protection effects and is very practical.
