Filtering core and water purification cup with filtering core

Abstract

The invention belongs to the field of outdoor articles and particularly relates to a filtering core and a water purification cup with the filtering core. The filtering core is composed of four layers of filtering layers which respectively comprise a loaded silver-containing mesoporous molecular sieve active carbon fiber filtering layer, an organic ion loaded zeolite and nano metal cluster material compound filtering layer, a chitosan medical stone compound filtering layer and a ceramic alkaline sphere filtering layer from top to bottom. The structure of the portable water purification cup with the filtering core and capable of heating comprises an upper cup body and a lower cup body; the portable water purification cup is small in volume, strong in water purification capability and convenient to use, and can meet the requirements on clean drinking water by people under the precondition of completely relieving the load of the people.

Description

technical field [0001] The invention belongs to the field of outdoor products, in particular to a filter element and a water purification cup containing the filter element. Background technique [0002] As the source of human life, water plays an irreplaceable role, but water pollution is becoming more and more serious. 70% of the rivers and lakes in our country are polluted to varying degrees, and the drinking water of more than 300 million people is unsafe. Nowadays, with the improvement of living standards, more and more people choose to go out of the house and go outdoors to experience the unique charm of nature. When people carry out outdoor activities, they often have insufficient drinking water. In the event of an extreme natural disaster emergency, due to limited conditions, people cannot completely clean the water in the field before drinking it, and cannot effectively isolate bacteria and heavy metal ions in the water. Such substances harmful to the human body c...

Problems solved by technology

When people carry out outdoor activities, they often have insufficient drinking water. In the event of an extreme natural disaster emergency, due to limited conditions, people cannot completely clean the water in the field before drinking it, and cannot effectively isolate bacteria and heavy metal ions in the water. Substances that are harmful to the human body can easily cause people to get sick after drinking water, and in serious cases endanger life safety

Among the many water purification cup products at home and abroad, the filter element material generally uses one or several active materials such as granular activated carbon, and these materials are directly combined and installed in the water purifier. Although this can remove heavy metals, pesticides, organic matter, etc. , but cannot effectively sterilize, because bacteria will enrich and multiply on this kind of adsorption material. In order to sterilize, the active material needs to be silver infiltrated or chlorinated or iodized, which will bring secondary pollution and the process is complicated ; At present, the filter element of the water purification cup uses KDF as the filter material to achieve the purpose of sterilization, but KDF is easy to form a block during use, which increases the pressure loss, thereby affecting the flow rate of water and the effect of water purification, and the water outlet The concentration of copper and zinc ions increased more

However, if the water purifier is equipped with a porous ceramic filter element or a sintered porous polymer material, a hollow fiber filter membrane, etc., although it can block some bacteria, it cannot effectively remove harmful substances such as heavy metals, pesticides, and organic substances; Level treatment, using a variety of materials to make up for the defects of the aforementioned filter element, but the structure of this filter element is complex and the price is high

Not only that, the structure of the water purification cup is relatively simple, and most of them are composed of a simple combination of a pressurizing device and a filter element. Even if some cups are designed with a flow detection method, the method is relatively rough

Generally speaking, the current water purification cup is not ideal
