Description

Apparatus for connecting filter in water purifier}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter of a water purifier, and more particularly, to a filter connecting device of a water purifier, which is coupled to both ends of a filter and integrally forms a flow path passing through the filter, and at the same time easy to replace the filter.

In general, a water purifier is a device for filtering natural water (hereinafter referred to as raw water) such as tap water or weak water, and the raw water is passed through various kinds of filtering means to remove foreign substances or harmful substances contained in the raw water. It is a device for providing drinking water containing only substances beneficial to the human body.

1 is a perspective view showing a mounting state of a filter of a conventional water purifier.

As shown, the supplied raw water is purified by clean water as it passes through the plurality of filters 1, and the types of the filters 1 are largely divided into a sediment filter 10 and a pre-carbon filter. carbon filter; 20), reverse osmosis membrane filter (membrane filter) 30, post-carbon filter (40).

First, the sediment filter 10 removes fine particles or debris in raw water by using a stepwise filtration method.

Next, the free carbon filter 20 effectively absorbs and removes chlorine and organic chemical components in water to effectively remove residual chlorine as well as a protective function of the reverse osmosis membrane filter 30 described later.

In addition, the reverse osmosis membrane filter 30 removes various contaminants such as bacteria and heavy metals, carcinogens, bacteria through fine pores of 0.001 microns.

Finally, the post carbon filter 40 removes odor-causing substances by using coconut shells, and adds silver ions to block microbial propagation and improve water taste.

The plurality of filters 1 are connected to each other by a plurality of tubings 50 and fittings 60, which are filter connecting devices, which connect the filters 1 to the tubing 50. The member is a fitting 60.

In addition, the fitting 60 uses the 'A'-shaped fitting 60 or'-'shaped fittings (not shown) to connect the filters 1 and the tubing 50 according to the configuration direction of the pipe. Will be connected to each other.

By the way, when each of these filters (1) is used for a predetermined time or more, in order to fulfill the function it is to be replaced according to the replacement cycle.

In particular, even if the amount of water used is small, various oxides already accumulated in the filters 1 may accumulate as the amount of water decreases, so that the particle holes of the filters 1 may be blocked and water may not come out.

Therefore, the use of a water purifier by replacing it with a normal product according to the replacement timing of the filters 1 is a way to drink clean water for a long time.

Currently, various kinds of filter connection devices have been developed to smoothly replace the filters 1.

2 is a partial perspective view illustrating a process of replacing a filter of a conventional water purifier.

As shown, this fitting 60 is fitted with tubing 50 at one end and nipples of the filters 1 at the other end. In addition, the tubing 50 and the portion where the nipple is fitted is provided with a support 61 and an O-ring (not shown) to prevent leakage.

When the nipple is fitted to one end of the fitting 60 by the filter connecting device having the above configuration, the nipple is first inserted while opening the support 61 and passed through the O-ring. The fitting of the tubing 50 at the other end is almost similar.

Accordingly, the tubing 50 and the nipple are fixed by the action of the support 61 which is elastically returned, and the watertightness can be maintained by the O-ring.

On the contrary, when the nipple of the tubing 50 or the filter 1 is to be released from the fitting 60, the end of the support 61 exposed to the outside is pressed using the filter replacement tool 70 or the finger. As the support 61 is lifted from the tubing 50 or the nipple, it becomes possible to release the nipple or the tubing 50 of the filters 1.

However, since the filter connecting device of the water purifier by the fitting is connected by using tubing to form a flow path between the filter and the filter, the internal configuration becomes complicated, which lowers the completeness of the product and the tubing or the fitting during the filter replacement. There were many problems that might be broken.

In addition, the filter must be replaced after using the filter replacement tool at the time of after-sales service. Therefore, it is inconvenient to replace the filter directly by the general consumer. In consideration of the difference in diameter, there were other problems that must be provided with a large number of parts, such as 'a' or 'ㅡ' fittings.

In addition, although not shown, in order to fix the filter inside the water purifier to install a separate holder on the inner wall of the water purifier, there is another problem that the design freedom of the product is lowered and the cost and process of the product is complicated.

The present invention has been made in view of the above, and a filter connection device for a water purifier capable of compact design of a product by simplifying a complicated flow path configuration generated by tubing or fittings installed to connect a filter and a filter. The purpose is to provide.

In addition, the present invention provides a filter connecting device of a water purifier that can be easily replaced by the general consumer without a filter replacement tool or a professional AS technician at the time of replacing the filter while using a standard filter already mass-produced and widely distributed in the market. There is another purpose.
