Joint for Integrated Coupling Pipe

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a joint-piece joint, and more particularly, to a joint-piece joint of a new structure that is coupled to a port of a water filter in a one-touch manner and is simply connected to a neighboring water filter.

Generally, a water purifier is a device for purifying or filtering natural water (hereinafter, referred to as raw water) such as tap water, bottled water, or weak water, and the raw water is included in raw water by passing through various kinds of filtering means. It is a device that provides drinking water containing only substances beneficial to the human body by removing the foreign substances or harmful substances.

Such a water purifier has a general water purifier having a simple purification function to filter raw impurities, bacteria, heavy metals, etc. included in raw water by passing raw water through several stages of water filters, and a cooling device and a heating device are added to the general water purifier. It is classified as a cold and hot water purifier that provides cooling water or hot water by simultaneously cooling or heating water.

As shown in FIG. 1, the water filter of the conventional water purifier includes a sediment filter 1, a pre-carbon filter 2, a reverse osmosis membrane filter 3, and a post. It comprises a carbon filter 4 (post-carbon filter).

The sediment filter 1 removes, by a nonwoven fabric, macro-sized foreign substances such as rust, soil, sand, and suspended solids contained in raw water introduced through a hose connected to a faucet.

The precarbon filter 2 removes chlorine components (trihalomethane, etc.), organic chemicals, etc. remaining in the water by the adsorption method of activated carbon made by burning minerals or palm trees at high temperatures.

The reverse osmosis membrane filter 3 removes various contaminants such as bacteria, inorganic substances, heavy metals, carcinogens and bacteria in the water through micropores having a size of 0.0001 micron by using a polyamide composite membrane. Here, the impurities (concentrated water) to be filtered are discharged to the designated place outside through the control valve (5).

The post carbon filter 4 uses a coconut shell or the like to purify foreign substances such as odors and gas components in the water, and adds silver ions to block the growth of microorganisms and improve the taste of water.

These multiple water filters are connected to each other by a filter cartridge connecting device.

As shown in FIG. 2, the filter cartridge connecting device for the water purifier according to the prior art has a collet 7 coupled to a port 6 of a water filter which is connected in series and is detachably coupled to one end thereof, and adjacent water An elbow-type joint 10 in which the collet 8 to which the tube tube 11 of the flexible synthetic resin material is coupled to be detachably coupled to the other end is used to connect the filters 1 and 2 to each other. Here, the collets 7 and 8 are formed in the opposite direction in which the port 6 and the tube tube 11 are coupled by hydraulic pressure or vibration by the reverse catching jaw 9 of the insert plate of the stainless steel inserted during injection molding. The outer periphery of the port 6 and the tube tube 11 is pressurized so as not to be separated.

As an example, each elbow is cut through a tube tube 11 which is cut to have a predetermined length while the elbow joint 11 is coupled to the port 6 of the sediment filter 1 and the precarbon filter 2. It is fitted to the type joint 10 in a one-touch manner. At this time, the tube tube 11 is prevented from being separated from the collet 8 by the reverse catching jaw 9 of the collet 8, and between the collector 8 by the O-ring 12 provided in the joint 10. Leakage is prevented.

In addition, when separating the tube tube 11 from the elbow-type joint 10 to check or replace the water filter, when the outer end of the collet 8 is pressed in the axial direction, the elastic piece 8a of the collet 8 This radial direction is expanded, which causes the pressing force of the reverse catching jaw 9 against the tube tube 11 to be weakened so that the tube tube 11 can be separated from the collet 8.

However, in the conventional elbow joint, the collet 7 and 8 are coupled to both ends thereof, and the structure thereof is very complicated, and the tube tube 11 is fitted to the collet 8 so as to be connected to a neighboring filter. There is a problem that the separation operation is not easy.

In addition, due to the large number of coupling parts such as O-rings 12, collets 7, 8, and tube tubes 11, the cost of the products is increased, and the completeness of the product is lowered. There is a problem that the tube is damaged.
