The present invention relates to a connector for a water filter and a locking structure of the filter housing such that the filter housing detachably coupled to the water filter connector is not easily separated from the connector.

More specifically, the filter housing and the filter housing of the filter housing which can prevent the filter housing detachably coupled to the connector from being easily separated from the connector due to the water pressure generated inside the filter cartridge. It relates to a locking structure.

In general, water filters built in filter housings, such as water purifiers, accumulate various pollutants (e.g., suspended solids, etc.) over time, and are used with periodic replacement of water filters or filter housings with built-in water filters. . At this time, at least one sealing seal (referred to as an O-ring) is mounted on the outer surface of the discharge port of the filter housing so as to maintain airtightness at the contact surface with the connector. In other words, the sealing seal prevents leakage at the contact surface between the connector and the filter housing.

As shown in FIG. 1, the locking structure of the connector for a water filter and the filter housing according to the prior art includes a pair of locking jaws 2 symmetrically formed on an inner surface of a coupling groove of the connector 1,

It is formed on the outer surface of the discharge port 4 of the filter housing 3 to correspond to the above-described locking jaw (2), when the filter housing 3 is rotated in one direction with respect to the connector 1, it is seated on the locking jaw (2) And a wing-shaped protrusion 5 to detachably lock the filter housing 3.

In the figure, reference numeral 6 denotes a raw water inlet through which raw water, such as tap water, flows from the outside into the connector 1, and 7 denotes a purified water treated by the filtration function of the filter housing 3 coupled to the connector 1. Water purification outlet discharged to the outside.

On the other hand, when various contaminants such as suspended solids contained in the raw water are accumulated by using the above-described water filter in the filter housing 3 for a long time, the water filter or the filter housing 3 in which the water filter is built is periodically Replace with and use. That is, the user separates the filter housing (3) from the connector (1) to replace the water filter.

The locking structure of the connector and the filter housing of the prior art is that when the filter housing 3 is rotated in the forward direction (clockwise) with respect to the connector 1 described above, the bottom surface of the protrusion 5 is caught. Since it slides along the upper surface of the), the protrusion 5 is locked to the locking jaw (2). This prevents the filter housing 3 from being arbitrarily separated from the connector 1.

On the other hand, in the state in which the filter housing 3 is coupled to the connector 1 described above, when the filter housing is rotated in the reverse direction (referring to the counterclockwise direction), the bottom surface of the protrusion 5 is caught by the locking jaw 2. Since the sliding along the upper surface of the locking projections (5) for the locking step (2) is released. This separates the filter housing 3 from the connector 1.

On the other hand, when a hydraulic pressure or a shock applied to the rotational force applied to the inside of the filter cartridge is applied, the protrusions 5 each formed in the horizontal structure can be easily slipped along the locking jaw (2) can be unlocked. Therefore, there is a problem that the filter housing 3 can be separated from the connector 1.

Embodiments of the present invention, the filter housing detachably coupled to the connector and the water filter or connector for the water filter so that the reliability is not easily separated from the connector due to the hydraulic pressure generated in the filter cartridge, or the impact applied to the rotational force, etc. It relates to the locking structure of the filter housing.
