Sucking water purification filter core and purifying direct drinking bottle provided thereon

Abstract

This invention discloses a sucking water purification filter core and a purifying direct drinking bottle provided thereon, wherein the sucking water purification filter core comprises a hollow fibre membrane component and a sealing connector, while the hollow fibre membrane component consists of a connector and a hollow fibre membrane, two ends of the hollow fibre membrane form a U shape with the connector, one end of the sealing connector is connected with the connector, the other end thereof is provided with a water outlet nozzle, and the inner part of the sealing connector is provided with active carbon or the combination of active carbon and copper-zinc alloy filter. Water taken by the sucking water purification filter core in the invention from the polluted water source can be drunk by mouth directly without using electricity and fossil energy as the motive power, and the water sucked into human body is in accordance with the national health standard for drinking water quality, in particular, the invention can solve the drinking water problems in all types of disasters such as earthquake, flood, debris flows, nuclear, biological and chemical (NBC) contaminations leaking happened in factories and the like.

Description

technical field [0001] The invention belongs to the field of water treatment, and in particular relates to a mouth-suction water purifying filter element and a purified direct-drinking water bottle provided with the mouth-suction water purifying filter element. Background technique [0002] At present, the pollution of surface water sources is quite common and serious. Even in remote areas, water sources are often polluted by pesticides, fertilizers, livestock and poultry manure, industrial wastewater, residential areas and hospital sewage. In addition, in the event of various sudden disasters such as earthquakes, floods, mudslides, and leakage of nuclear, biological and chemical pollutants from factories, water source pollution is even more inevitable. When individuals are working in the field, if they drink unqualified polluted water, they will be injured, and it is very inconvenient to carry a sufficient amount of drinking water once. Therefore, it is very necessary to p...

AI Technical Summary

Problems solved by technology

[0003] In the past, the water purification filter element of personal water purifier technology mostly used activated carbon or ceramics as the water purification material. The filter material of these technologies is to pack activated carbon and disinfectant (such as iodine resin or silver-loaded activated carbon) in a certain order in a cylindrical container. , and some process the filter material into a cylindrical filter element with micropores by sintering or bonding, and then the water passes through the filter cartridge to achieve the effect of water purification under the action of a specially designed external pressure system, which is easy to block and difficult to regenerate In addition, because the filtration accuracy is usually above 1 μm (often requiring a large external pressure), bacteria cannot be completely filtered out, and it is often necessary to add chemical bactericides as a means of auxiliary sterilization, and the added chemical bactericides often lead to The effluent is smelly, and the short-term contact between microorganisms and chemical bactericides is often difficult to achieve sufficient bactericidal effect
