Description
Technical Field
The invention relates to the field of water treatment, in particular to a water filtering filter element.
Background
About 100 ten thousand plastic bottles were statistically sold worldwide per minute. This number will continue to increase as the market demand for bottled water, beverages, and the like increases. After the bottled water and bottled beverage are drunk, most of plastic bottles of the bottled water and the bottled beverage can be discarded, so that the resource waste is caused.
In addition, bottled water and bottled beverages have a shelf life, and the quality of the bottled water and bottled beverages is reduced with the increase of the selling time or the storing time.
Disclosure of Invention
The invention aims to provide a universal filter element for a plastic bottle, so as to solve the technical problems.
The technical problems solved by the invention can be realized by adopting the following technical scheme:
the plastic bottle universal filter element comprises a cover main body for closing the bottle mouth of a plastic bottle, wherein the cover main body comprises a cover top and a cover wall connected below the periphery of the cover top, and is characterized by further comprising a tubular insertion tube, wherein the upper port of the insertion tube is connected to the lower end face of the cover top, the lower port of the insertion tube is not closed, and the lower port of the insertion tube is used as a water inlet of the insertion tube; the cover top is provided with a first through hole penetrating up and down, the first through hole is communicated with the inner cavity of the cannula, and the first through hole is used as a water outlet of the cannula; a filtering module for filtering water is arranged between the water inlet and the water outlet.
The filter module of the present invention is constructed on a cap body for closing the mouth of a plastic bottle, and has the following advantages: on the one hand, the plastic bottle can be matched with a plastic bottle of bottled water or bottled beverage after drinking, and the plastic bottle is used as a filtering container of the filtering device, so that the filtering container is not needed to be purchased additionally, and the cost of the filtering device is reduced while the waste utilization of the plastic bottle is realized. On the other hand, can assemble to bottled water fast, carry out secondary filtering to bottled water to improve and sell time or the problem that the holding time overlength caused the quality to decline.
As a preferred solution, a distance exists between the upper end face of the filter module and the lower end face of the cover top, so that a containing cavity is formed at the upper part of the cannula, and nothing is placed in the containing cavity. Under this scheme, when drinking, empty the body of plastic bottle, water passes filtration module and reachs and hold the chamber, then passes and hold the chamber and flow from first through-hole, after stopping drinking, stand up the body, hold the water in the chamber and slowly pass filtration module back in the plastic bottle. The containing cavity can increase the amount of the water flowing back, so that the time that the filter module is wet with water is prolonged, the problem of long water outlet waiting time caused by the fact that drinking water needs to wet the filter module first and then outlet water is solved, and the filter material aging condition caused by the fact that the filter material in the filter module is dry and wet state is frequently switched is solved.
As another preferable scheme, when the plastic bottle universal filter element is used for filtering water, a distance exists between the upper end face of the filtering module and the lower end face of the cover top, so that a containing cavity is formed at the upper part of the insertion tube, and functional materials are contained in the containing cavity. Functional materials are contained in the containing cavity, and the functional materials are cold-brewing tea leaves. Compared with bottled tea, the scheme is cleaner when water for making tea is filtered by the filtering module; the tea provided by the invention is drunk along with brewing, can effectively avoid the problems of low effective components and increased harmful components of the night tea and is healthier.
