Description

Downstream regeneration type tap water softener

Technical Field

The utility model relates to a water softening installation especially relates to a following current regenerative faucet water softener, wherein the utility model discloses following current regenerative faucet water softener is set up and is suitable for and is connected with tap to soften and purification treatment raw water (or running water). Further, the utility model discloses following current regeneration formula tap water softener is set up and is suitable for following current regeneration.

Background

With the increasing improvement of living standard and the increasing emphasis on health of people, the quality requirement of people on domestic water is higher and higher. However, in many countries, particularly in developing countries, many sources of tap water are relatively hard ground or surface waters that, after being purified and disinfected, are supplied to users for use. Tap water having a relatively high hardness tends to damage the protective layer of the skin, resulting in dry and astringent skin of the user and even skin allergy. In addition, tap water having a high hardness may also affect the cleansing effect of the skin cleansing article and the cosmetic effect of the cosmetics. Therefore, when the tap water having a high hardness is used to wash the face, the user experience is poor. While water having a lower hardness, such as that obtained by softening tap water, is more mild to the skin of the user due to its low irritation, and is more suitable for use in cleansing the skin and making up beauty. For example, when cleaning the face.

However, the softening device, especially a small-sized softening device for makeup and/or beauty use, has a limited content of softening resin, and loses its softening effect on raw water or water to be treated after a certain period of use, and thus, it is required to be regenerated for further use. The regeneration problem is not considered at all in some existing small-sized softening devices, and users have to discard the small-sized softening devices after losing the softening function after using the small-sized softening devices for a period of time. The other part of the existing small softening device realizes the regeneration of the softening device by taking out the softening resin in the softening device and soaking the softening resin in salt solution. The method for realizing regeneration of the softening device by taking out the softened resin in the softening device and soaking the softened resin in the salt solution needs to disassemble the softening device, and is difficult. In addition, frequent disassembly of the softener also affects the sealing effectiveness and the service life of the softener.

The chinese utility model patent of application number 201620190999.5 discloses a filter core, filter element group spare and have the water treatment ware of washing one's face and rinsing one's mouth of filter element group spare, and wherein the softening filter core of the water treatment ware of washing one's face and rinsing one's mouth that has filter element group spare that this utility model patent discloses can carry out softening treatment to water. However, this utility model does not provide any mechanism for adding a regeneration solution, such as a salt solution, to its softening cartridge. In addition, the softened material of the washing water treater with filter element group spare that this utility model patent discloses does not separate and places, leads to raw water or pending water short and lead to the treatment effect of this utility model patent discloses a washing water treater to the raw water of the route of flowing through of washing water treater not good.
