Desk type simple water dispenser

Abstract

The invention relates to a desk type simple water dispenser which comprises an electrolysis unit and a membrane filter unit. The electrolysis unit comprises at least a pair of positive electrode and negative electrode, an electrolysis power supply and a water tank. The electrolysis power supply supplies power for the positive electrode and the negative electrode. A water-permeable diaphragm made of a non-conductive material is arranged between each pair of negative electrode and positive electrode; the water tank is provided with a first water inlet and a first water outlet, the positive electrode is separated from the water tank by the water-permeable diaphragm, and the negative electrode is disposed in the water tank. The membrane unit is provided with a second water inlet and a second water outlet which are communicated with each other. During use of the desk type simple water dispenser, each negative electrode is in direct contact with water stored in the water tank, each positive electrode is in contact with the water tank via water permeated from the water-permeable diaphragms only, and thus a water film is sandwiched between the positive electrode and the water-permeable diaphragm. The water dispenser has the advantages that contaminant in source water can be removed effectively, bacteria in source water can be inactivated completely, toxic and side products are avoided, and the water dispenser is reliable in operation and long in service life.

Description

technical field [0001] The invention relates to a simple desktop water dispenser, which belongs to the technical field of drinking water terminal water quality treatment. Background technique [0002] At present, the water environment is deteriorating, and drinking water quality and safety accidents occur frequently, which has seriously endangered human survival. Water pollution is mainly caused by pollutants produced by human activities, including industrial pollution sources, agricultural pollution sources and domestic pollution sources. Increasing water pollution has posed a major threat to human survival and has become a major obstacle to human health, economic and social sustainable development. According to the investigation of the authoritative organization in the world, at least 20 million people in the world die every year due to drinking unsanitary water. Therefore, water pollution is called "the number one killer in the world". [0003] Most waterworks at home a...

Problems solved by technology

The common deficiencies of these technologies are that firstly, the overall design of the system is not considered, and only local single measures often make the overall work of the system unbalanced; secondly, they do not consider starting from improving the water inlet conditions of the membrane elements to reduce the workload of the membrane elements , can be said to be "a temporary solution but not a permanent cure", so no real practical and commercial products have come out so far

[0005] In contrast, although the chemical water treatment process has many advantages such as cheap, simple and efficient, it is an excellent advanced oxidation process, but there are a series of problems in the electrochemical treatment itself, and it is not suitable to be used alone in the treatment of drinking water in civilian terminals. It has not been widely used in daily water treatment occasions

The reason is that the chemical water treatment process needs sufficient reaction time, but in the daily water situation, the water purifier is only a few seconds from the start-up to the water discharge, and the residence time of the pollutants in the water purifier is too short to complete the relevant process. Chemical reaction treatment; secondly, the chemical water treatment process may be accompanied by certain toxic and side effects

For example, although the chemical oxidation reaction process can effectively inactivate bacteria, deeply degrade organic matter, and remove various harmful substances in water, the various strong oxidation factors generated by chemical oxidation are basically non-selective and uncontrollable. Improper use is very likely to produce new substances that are not in the source water, which will endanger the safety of drinking water; because of this, the application of chemical water treatment processes can be said to be cautious in the daily drinking water purification treatment of the public
