Technical Field

The utility model relates to a water softening device, in particular to a faucet water softener, wherein the faucet water softener is suitable for softening raw water (or tap water). Further, the faucet water softener is provided and is suitable for being connected with a faucet to soften raw water.

Background

With the increasing improvement of living standard and the increasing emphasis on health, 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 softened water obtained by softening tap water, is milder to the skin of a user due to its low irritation, and is more suitable for use in cleansing the skin and making up and beautifying. For example, when cleaning the face.

However, the softening device, particularly a small softening device for makeup and/or cosmetology, 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 can be used continuously after being subjected to a regeneration treatment. Some existing small-sized softening devices do not consider the regeneration problem at all, and users have to discard after losing the softening function after using 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 the 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 has higher difficulty. In addition, frequent disassembly of the softener also affects the sealing effectiveness and the service life of the softener.

Referring to fig. 1 to 9 of the drawings, a faucet water softener according to an embodiment of the present invention is illustrated, wherein the faucet water softener includes a water treatment device 1 and a first hose 31, wherein one end of the first hose 31 is adapted to communicate with a source of raw water, such as a faucet, and the other end is adapted to communicate with the water treatment device 1, so that the raw water can flow from the source to the water treatment device 1 under the action of water pressure and be softened by the water treatment device 1 to generate softened water. Most of the softened water produced by the existing water softeners is used for bathing, washing clothes and the like, has large volume, is installed and moved less, and the water softeners are generally communicated with a raw water source through hard pipes such as plastic hard pipes and stainless steel pipes. However, the water treatment apparatus 1 of the faucet water softener of the present invention is connected to a raw water source, particularly a faucet, through a hose, the first hose 31, to be more convenient for a user to use in a kitchen or a dressing table or a washbasin (between a dressing room and a restroom) having a limited area. Generally, the area of an operation table and a dressing room near a kitchen sink is limited, and the operation table and the dressing room are connected by using a hard pipe, so that the operation table occupies a larger volume, and the hard pipe cannot be moved, so that inconvenience is brought to the use of the faucet water softener. In particular, many faucets, such as kitchen faucets, have a rotatable spout for ease of use. If the hard pipe connection is used, the water outlet pipe of the tap water faucet cannot rotate. The water treatment device 1 of the tap water softener of the utility model is connected with a raw water source, especially a tap, through a hose, and the first hose 31 does not influence the rotation of the tap (or a water outlet pipe thereof).
