Tap water purification device

Abstract

The present invention discloses a tap water purification device comprising a tubular body, the tubular body comprises a tube wall, an upper connecting portion and a lower connecting portion, the upper connecting portion and the tube wall are formed integrally, the upper connecting portion is located at the upper end of the tube wall, the lower connecting portion and the tube wall are formed integrally, the lower connecting portion is located at the lower end of the tube wall, a first filter net is arranged above the lower connecting portion, the first filter net and the tube wall are formed integrally, a first annular projection part is arranged below the upper connecting portion, the first annular projection part is arranged along the circumferential direction of the tube wall, the upper section of the first annular projection part is provided with a first annular concave which is radially outward, the first annular concave is internally is provided with a second filter net, the first filter net and the second filter net are arranged in parallel perpendicular to the axial direction of the tube wall, a cavity is formed between the first filter net and the second filter net, and a cleaning agent for tap water purification is put in the cavity. The tap water purification device is simple in structure, the filter nets are easy to wash and remove, replacement of the cleaning agent is easy, dechlorination effect is good, and after home purchase, the tap water purification device can be installed voluntarily.

Description

technical field [0001] The invention belongs to the technical field of water purification equipment, and in particular relates to a tap water purification device. Background technique [0002] More than 80% of the tap water plants in the world use chlorine as an effective means of sterilization and disinfection. In order to ensure the safety of microbial indicators in drinking water, a certain amount of residual chlorine must be maintained in tap water. The allowable range of residual chlorine in my country's tap water quality standard is 0.2-1.5ppm, generally lower than 1.0ppm. Residual chlorine not only has certain harm to human health, but also causes unpleasant smell in water. At the same time, it will produce many chlorine by-products, which are even more harmful to human body than residual chlorine itself. For example, when residual chlorine in tap water combines with organic matter in water, carbon tetrachloride, dichloroethanol, and trihalomethane are produced. Thr...

Problems solved by technology

[0003] The existing method for removing residual chlorine is mainly to dry it in the sun. However, it is impossible to dry all the water in our daily life before using it. In the existing water purification device, the filter element uses membrane filtration and adsorbent to purify tap water, which requires high investment. The filter element is inconvenient to replace, and some metal elements that are beneficial to the human body are often filtered out, and long-term drinking is not conducive to health
