Abstract

The present invention relates to a filter housing for a water purifier used in a water treatment apparatus, and an object thereof is to provide a housing that can withstand a considerable amount of water leakage.

Conventional water filter housing for water purifier has a support jaw at the bottom of the female screw of the housing to prevent leakage of water introduced into the housing, and the elastic o-ring is fitted on the support jaw and pressed to the bottom of the male screw of the head. Since the O-ring is pushed out of the rounded jaw, it did not have a leaking effect. Therefore, the present invention is designed to solve this problem by turning the ring around the lower end of the main shaft of the male screw formed on the head. It is designed to maximize the sealing effect of the O-ring by preventing it from being pushed to the weak part.

The present invention incorporates a cylindrical filter (3) in the housing (1) and attaches to the head (2) to form a female screw (4) on the inner wall of the upper end of the housing (1) and to the bottom outer edge of the female screw (4). The "L" shaped jaw (7) with the annular ring (5) formed thereon is inserted into the "O" ring (6) of the elastic body, and the head (2) has a water inlet (8), a water outlet (9), and a water outlet. (9) is provided with an inlet (10) in communication with the outer wall of the cylindrical shaft of the head (2) to form a male screw (11) and the water ring for the water purifier with the annular ring (12) in the outer edge of the lower end 11 Filter housing.

Description

Filter Housing for Water Purifier

The present invention relates to a filter housing for a water purifier used in a water treatment apparatus, and an object thereof is to provide a housing that can withstand a considerable amount of water leakage.

The conventional water treatment device using a filter housing has a cylindrical filter, which is a water purification means, is built into the housing, and the head is provided with a raw water inlet, a purified water outlet, and a purified water inlet communicating with the purified water outlet, while pressing the filter to seal and fix the water. The purified water, which enters between the housing and the filter through the water inlet formed in the head, and is filtered through the cylindrical filter wall, enters the cylindrical filter and discharges through the purified water inlet formed in the head to the purified water outlet. At this time, in order to prevent the leakage of water introduced into the housing, the support jaw was recirculated at the bottom of the female screw of the housing, and an elastic "O" ring was inserted over the support jaw and pressed to the bottom of the male screw of the head to seal it. Since it was pushed out of the ring, it did not have a leak effect, so in order to solve this problem, the ring was rounded at the outer edge of the ring to prevent the "O" ring from being pushed out. However, under the threaded valley where the tip of the thread is located at the lower end of the female thread, the width and height of the bottom of the female thread are not constant on the inner circumferential surface of the female thread because of the slanted structure. .

The present invention requires these removable water treatment devices to be completely sealed, and in particular, they are connected to other water treatment systems and can leak due to vibrations caused by incidental water. Means were required.

In order to solve this problem, the present invention is designed to solve the problem of the “O” ring by preventing the “0” ring from being pushed out to the irregular weak part under the female screw at the bottom of the female screw by turning the ring to the outside of the lower end of the main shaft of the male screw. The sealing effect is obtained to the maximum.

The present invention incorporates a cylindrical filter (3) in the housing (1) and attaches to the head (2) to form a female screw (4) on the inner wall of the upper end of the housing (1) and to the bottom outer edge of the female screw (4). The L-shaped base jaw (7) formed with the annular ring (5) in the ring is inserted to connect the "0" ring (6) of the elastic body to communicate with the water inlet (8), the water outlet (9), and the water outlet (9). It is a filter housing for a water purifier in which a male screw 11 is formed on the outer peripheral wall of the cylindrical shaft of the head 2 provided with an entry port 10, and the annular ring 12 is turned on the outer edge of the lower end of the male screw 11.

Reference numerals 13 and 14 are barking.

Since the present invention is constructed in this manner, when attaching the head 2 to the housing 1, the lower end of the lower end of the male screw 11 of the head 2 is in contact with the lower end of the female screw 4 of the housing 1. 5) The "L" type support jaw 7 is formed so that the "O" ring 6 placed therein is not likely to be pushed outward and the bottom outside of the male screw 11 of the head 2. The rounded ring 12 is formed at the edge so that the round head 5 and the rounded ring 12 on the male thread side hold the " O " ring 6, It is completely sealed because there is no fear that the "0" ring will be pushed out at the weak part where the width of the female thread at the bottom of the bottom is not uniform.

The following table shows the test results tested by the Korea Testing Institute.

Test Result (Apr. 4, 1998)

* Elution condition: 60 ℃ × 30 minutes

This design is a very useful design that can prevent leakage when used in a water treatment device with high vibration because it is completely sealed and is safe even at the water pressure of water leakage 13.

Claims (1)

The cylindrical filter (3) is built in the housing (1), and the female screw (4) is cut on the inner wall of the upper housing of the housing (1), thereby turning the ring (5) on the bottom outer edge of the female screw (4) to insert a "0" ring. The L ”type base jaw (7) is provided, and the water inlet (8), the water outlet (9), and the inlet (10) are connected to the water outlet (9).
