Description

Filter structure for removing impurities {Impurities removing filter structure}

The present invention relates to a filter structure for removing impurities, and more particularly, to a filter structure for removing impurities that can be inserted into a water faucet such as a shower, washbasin, and sink to remove and purify impurities such as residual chlorine or rust in tap water. will be.

In general, toxic chemicals such as chlorine used as a disinfectant in tap water are absorbed into the body when showering, bathing, or washing dishes, and 2 to 3 times more penetrate into the body than when purifying tap water. do.

Here, chlorine that has penetrated into the body adversely affects health conditions in the human body, such as heart disease, arteriosclerosis, weakening of the circulatory system, pulmonary edema, damage to the gastrointestinal tract, genital or urinary organs, and chronic asthma.

In addition, when chlorine comes into contact with the skin during showering, washing face, or washing dishes, it accelerates the aging process of the skin, such as when exposed to ultraviolet rays, making the skin sensitive, drying and cracking, discoloring white, and worsening spots and freckles. There is a problem that eventually causes skin diseases.

For this reason, conventionally, a filter structure for removing impurities such as residual chlorine from tap water has been installed before the tap, such as a shower, a washbasin, or a sink.

However, most conventional filter structures have a structure in which a cylindrical nonwoven filter is inserted into the faucet and impurities are removed while tap water is simply transmitted from the outside of the cylindrical filter to the inside.

Accordingly, in the conventional filter structure, the water introduced between the installation space such as the cylindrical filter and the water faucet handle is concentrated into the inside of the filter in a state that almost reaches the upper end of the cylindrical filter by water pressure, and then fills the hollow at the top of the filter. Since it is discharged through the water, impurities are intensively collected only at the upper end of the filter through which water is discharged, so that there is a problem in that the impurity removal efficiency is greatly reduced.

In addition, in order to solve the above problems, a chlorine removal ball for separately removing residual chlorine is further filled in the injection nozzle part such as the head of the water faucet, but the cross-sectional area of the head part of the chlorine removal ball is Since the cross-sectional area of the flow passage through which the tap water is moved is larger, there is a problem in that the chlorine removal efficiency cannot be maximized because the amount of water injected to the outside without contacting the chlorine removal ball is large.

The discharge cap 300 is located in close contact with the inside of the handle 10 of the tap water sprayer, the upper end of the filter 200 is fitted, and the filter 200 is communicated with the inside of the filter 200 from the outside of the filter 200. As a means for allowing tap water from which impurities have been removed while penetrating into the interior to be discharged to the head of the faucet, the fitting cap 310 fitted to the outer peripheral surface of the upper end of the filter 200 and the fitting cap 310 are formed through the upper surface It includes a plurality of discharge holes 320 and the like so that the tap water that has passed through the filter 200 is discharged to the head of the water faucet.

Here, in the discharge cap 300 , an installation groove (unsigned) in which a contact ring (not shown) is mounted so as to be positioned in close contact with the handle 10 of the tap water sprayer may be formed on the outer circumferential surface of the fitting cap 310 . .

Therefore, according to the discharge cap 300, by fitting the upper end of the filter 200 coupled to the upper end of the chlorine removal housing 100, it is possible to facilitate replacement and installation of the filter 200.

Hereinafter, the operation of the filter structure for removing impurities according to a preferred embodiment of the present invention will be described.

First, a plurality of chlorine removal balls (B) are filled inside the housing body 110 of the chlorine removal housing 100 .

Here, the chlorine removal housing 100, when the housing body 110 has a hollow 111 on the center, the chlorine removal ball (B) is filled in the hollow 111, the housing body 110 is a space at the edge In the case of having (112), the chlorine removal ball (B) can be filled in the edge space (112).

In addition, in the chlorine removal housing 100, when the housing body 110 has a hollow 111 on the center, the tap water inlet hole 121 of the tap water inlet cap 120 communicates with the hollow 111, and the housing body When 110 has an edge space 112 , the tap water inlet hole 121 of the tap water inlet cap 120 communicates with the edge space 112 .

Thereafter, the tap water discharge cap 130 is coupled to the upper end of the housing body 110 .

Here, in the tap water discharge cap 130, when the housing body 110 has a hollow 111 on the center, the tap water discharge hole 132 communicates with the hollow 111, and the housing body 110 is connected to the edge space ( 112) has a structure in which the tap water discharge hole 132 communicates with the edge space 112.

Thereafter, the hollow at the lower end of the filter 200 is fixed to the tap water discharge cap 130 of the chlorine removal housing 100 .

Thereafter, the outer peripheral surface of the upper end of the filter 200 is fitted and fixed to the fitting cap 310 of the discharge cap 300 .

Thereafter, the filter structure assembled as described above is inserted into the handle 10 such as a shower, and at this time, the tap water inlet cap 120 of the chlorine removal housing 100 is fitted and coupled to the tap water inlet pipe 20 to tap water. The inlet hole 121 and the tap water inlet pipe 20 communicate with each other, and the discharge cap 300 is closely positioned on the inner circumferential surface of the inside of the handle 10 .

Accordingly, in the state as described above, when tap water flows into the inside of the handle 10 such as the shower through the tap water inlet pipe 20, the tap water is the tap water inlet hole of the chlorine removal housing 100 and the tap water inlet cap 120. Through 121, the chlorine removal ball (B) flows into the inside of the housing body 110 filled in the straight pipe and comes into contact with the chlorine removal ball (B), and residual chlorine is primarily removed.

Thereafter, the tap water in contact with the chlorine removal ball (B) is discharged into the space between the chlorine removal housing 100 and the handle 10 through the tap water discharge hole 132 of the chlorine removal housing 100 and the tap water discharge cap 130 . do.
