Description

Filter device for water purifier {Filter device for water purifier}

The present invention relates to a filter device for a water purifier, and more particularly, to a filter device for a water purifier configured so that water does not leak to the outside when replacing the main body of the filter device periodically or arbitrarily.

In general, some homes and businesses drink and drink fresh water to drink clean water and maintain health. However, most households boil or purify tap water or groundwater for economic or other reasons. In order to purify tap water or raw water, a home or a workplace is connected to a tap or a lake for supplying water before purification to a water pipe or raw water pipe, and then supplied with tap water to purify the purified water. Various types of water purifiers are installed, which are configured to be supplied to users.

As shown in FIG. 1, such a water purifier or water purifier basically purifies the inlet port 1 for receiving raw water by a hose not shown and the raw water supplied to the inlet port 1. And a discharge port 3 for supplying purified water from the main body 2 to the outside. In addition, the discharge port 3 is detachably inserted at the end of the discharge hose to provide purified water to the operator or the user. According to such a configuration, after tap water or raw water is supplied through the inlet port 1 through a hose, and purified by the filter member in the main body 2, the purified water passes through the discharge port 3 to discharge the discharge hose. It is supplied to the drinker or the user.

However, it has been shown that such conventional water purifier filter devices have caused some problems. First, when removing the end of the discharge hose from the discharge port to replace the filter body during long-term use of the water purifier or during regular filter change, water remaining in the discharge hose is ejected or leaked to the outside to wet or contaminate the surroundings. There is a problem. This problem has been found to be due to the fact that no discharge means is provided at the discharge hose or at the end thereof to prevent water from being discharged to the outside.

In addition, in order to temporarily solve the problems described above, after removing the end of the discharging hose from the discharge port, the filter is replaced after closing the discharging hose by using temporary means such as wood chips, rubber packing, etc. This can not prevent the complete leakage of water, there is a problem of long working time and inadequate hygiene.

The present invention has been made to solve the above problems, the object of the present invention is to provide a filter device for a water purifier that can completely prevent the ejection or leakage of water when the filter body is replaced.

Another object of the present invention is to provide a filter device for a water purifier having an upper manifold that can automatically close the end of the discharge hose when the filter is separated when the filter body is replaced.
