Abstract

The utility model relates to a drinking water filtering bag, comprising a bag body, a water inlet, a water outlet, and a filtering layer. The bag body is divided into the upper part and the lower part by the filtering layer, a water inlet is positioned at the upper top part of the bag body, and a water outlet is positioned at the lower part of the bag body. The filtering layer is at least one layer that is a polypropylene fiber film or a hollow fiber film conforming to the drinking water filtering standard. The drinking water filtering bag of the utility model whose the material of the bag body and the filtering layer obtain easily and have the low cost, the designs of the water outlet and the water inlet are simple and practical. The utility model is convenient for carrying and is suitable for use in field, and the drinking water filtering bag is disposable or reusable.

Description

The tap water filter bag

Technical field

The utility model relates to a kind of tap water filter bag.

Background technology

Some urgent occasion in actual life for example runs into natural disaster or lacks in the open air under the situation at clean water source, need use water filtering device.Existing commonly used tap water strainer, complex manufacturing technology, needing instrument to install can use, higher because of cost, costs an arm and a leg and is not suitable for above-mentioned occasion and uses.

Summary of the invention

The purpose of this utility model is for a kind of low cost, application and tap water filter bag easy to carry are provided.

Tap water filter bag described in the utility model comprises bag, water-in, water outlet and filtering layer, and bag is filtered layer and is divided into two portions up and down, and water-in is positioned at the bag upper top, and water outlet is positioned at the bag bottom; Filtering layer meets the polypropylene fibre film or the hollow type fiber membrane of tap water filter criteria for one deck at least.

The standard of the filtering layer that the utility model adopted is to make the water quality after the filtration meet national Drinking Water water quality standard, is example with the bacteriology index, and total plate count is less than 100/ml, and total coli group is less than 3/L.Can select sophisticated filtering material such as polypropylene fibre film on the market, products such as hollow type fiber.Add layer of active carbon at least, can filter peculiar smell and pigment.Also can the position below filtering layer add the pore design, be convenient to discharge the tap water behind bag inner filtration.

Can be provided with the handle position on the bag of tap water filter bag, be convenient to carry; Perhaps on bag, be provided with the wire rope handling position, fasten rope band after, can be directly portable, or be fixed in knapsack.

Tap water filter bag described in the utility model, bag and filtering membrane material therefor more easily obtain and also cost low, the also simple and easy practicality of the design of water-in, water outlet is easy to carry and field usage, is generally disposable use, also can repeatedly use.
