The present invention relates to a filter cartridge connection structure for a water purifier, and more particularly, when a filter cartridge is replaced, a solenoid valve installed in the water supply pipe is operated by supplying water by contacting and releasing the on / off switch attached to the handle. It has a first opening and closing function to shut off, and has a second opening and closing function to lock the water by shifting the water through hole of the connector and the water through hole of the flow pipe when rotating the connector coupled to the water pipe, the filter When the cartridge is disconnected from the connector, it has a third opening and closing function that automatically closes the opening / closing valve of the connector, thereby preventing the water in the connection from leaking to the outside, making it safe, easy and simple when the public replaces the filter cartridge. The filter cartridge can be replaced.

Recently, due to serious water pollution problems, water purifiers are widely used in places where drinking water is needed, such as homes, restaurants, restaurants, department offices, schools, and construction sites.

In general, a water purifier is installed in the water purifier to go through a number of filtration steps to remove bacteria, impurities, or odor contained in tap water.

The life of the filter installed in the water purifier may vary depending on the water quality, but the filter cartridge should be replaced periodically.

However, in order to replace the filter cartridge, conventionally, a separate fitting (fitting) was connected to the water inlet pipe formed at the upper portion of the filter cartridge and used to connect to the tap water inlet pipe. Since the filter cartridge must be replaced after removing the fitting, it was too difficult and cumbersome for the general consumer to replace the filter cartridge, and the replacement cost was paid to a specialist.

In addition, in order to prevent leakage of tap water from the filter cartridge when replacing the filter cartridge, operate the on / off valve installed at the proper position of the water pipe to the closed position and then perform the replacement work. There was a troublesome problem to do.

The opening and closing valve 41 of the connector 40 is composed of an O-ring 44, a water passage pad 45, a spring 46, a valve 47, an O-ring 48 in the valve seating pipe 49. do.

A pad 75 and a cross valve 76 are formed in the water inlet / outlet pipes 71 and 72 of the filter cartridge 70, and a water passage hole 74 is formed on the ring 73. ), The spring 77 and the O-ring 78 is characterized in that installed sequentially.

The connector 50 coupled to both sides of the water pipe 40 is rotated at a predetermined angle in the forward direction so that the water through holes 52 formed on both sides of the connector 50 are formed on both sides of the water pipe 40. It is characterized in that the flow of water is blocked by shifting each other from the hole (43).

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention in more detail as follows.

1 is a front view showing the overall configuration according to the present invention, Figure 2 is a partial side cross-sectional view showing a state in which the filter cartridge is coupled according to the present invention, Figure 3 is a state for separating and combining the filter cartridge according to the present invention 4 is an enlarged cross-sectional view taken from the "a" part of FIG. 1, FIG. 5 is a cross-sectional view of the filter cartridge separated from the connector in Figure 4, Figure 6 is "b" in FIG. It is an exploded perspective view which extracts and enlarges the main part of a part, and FIG. 7 is a partially enlarged perspective view which extracts the "multi" part of FIG.

1 to 2, in order to replace the filter cartridge 70 in the water purifier main body 1, first open the door 90 installed on the front of the water purifier main body 1, and then support the lower part of the filter cartridge 70. The pressing member 23 of the supporting member 20 is pressed.

As shown in FIG. 3, when the pressing member 23 is pressed inwards, the handle 50 fixed to the rear portion of the connector 40 to which the upper portion of the filter cartridge 70 is coupled is held by hand and at a predetermined angle in the forward direction. Rotate

At this time, the solenoid valve on / off switch 60 attached to the rear of the handle 50 is separated from the switch 61 installed in the first bracket 10 and the power is turned off. By the operation of the solenoid valve 32, the water flowing to each of the flow pipes (30a) (30b) (30c) is first blocked.

In addition, as shown in FIG. 8, the water passages 30a and 43 are formed by shifting the water through-holes 33 and 43 respectively formed at both sides of the water flow pipes 30a, 30b and 30c and the both sides of the connector 40, respectively. (30b) 30c and the water through holes 33 and 43 of the connection 40 are blocked, so that water flows secondarily.

 The water inlet / outlet pipe 71 of the filter cartridge 70 inserted and coupled to the on / off valve 41 of the connector 40 in a state in which the filter cartridge 70 coupled to the connector 40 is rotated at a predetermined angle. 72) to separate the filter cartridge 70 from the connector (40).

When the water inlet / outlet pipes 71 and 72 of the filter cartridge 70 inserted into the opening / closing valve 41 of the connector 40 are separated in a coupled state, the valve seating pipe 49 is shown in FIG. 5. The inside of the valve 47 is installed downward to block the water outlet by the elastic force of the spring 46 so that the water in the connector 40 is not discharged to the outside.

In addition, the cross valve 76 installed in the water inlet pipe 71 and the outflow pipe 72 of the filter cartridge 70 is also moved upward by the elastic force of the spring 77 so that the upper surface of the cross valve 76 is closed. It is in close contact with the edge surface of the O-ring 78 is installed on the top to block the water inlet tube 71 and the outlet tube 72.

In this way, the water inlet pipe 71 and the outlet pipe 72 of the opening and closing valve 41 of the connector 40 and the filter cartridge 70 are blocked by the respective valves due to the spring force of the springs 46 and 77. Therefore, even if the filter cartridge 70 is separated from the connector 40, water is not discharged to the outside, so that the filter cartridge 70 can be easily replaced.

Meanwhile, in order to couple the filter cartridge 70 to the connector 40, the water inlet pipe 71 and the outlet pipe 72 of the filter cartridge 70 are coupled to the on / off valve 41 of the connector 40. As shown in the lower portion of the valve seating pipe 47 of the connector 40 is in close contact with the upper surface of the cross valve 76 installed in the water inlet pipe 71 and the outlet pipe 72 and pushed downward to the water inlet pipe The valve of the 71 and the outflow pipe 72 is opened.

In addition, the upper end of the cross valve 76 installed in the water inlet pipe 71 and the outlet pipe 72 of the filter cartridge 70 is in close contact with the lower surface of the valve 47 of the connector 40 to open the valve. Water passing through the connector 40 passes through the filter cartridge 70 to purify the water.

The filter cartridge 70 coupled to the connector 40 as described above is replaced with a new one, and then, as illustrated in FIG. 3, the filter cartridge 70 and the handle 50 connected to the connector 40 are held to hold the water purifier body 1. When pushed in the direction, the connector 40 coupled to the flow pipes 30a, 30b, 30c is rotated by the hinge axis.

At this time, the solenoid valve is opened while the solenoid valve on / off switch 60 provided at the rear of the handle 50 is in contact with the switch 61 fixed to the first bracket 10, and the flow pipes 30a and 30b are opened. The water supply pipe 33 formed on both sides of the 30c is positioned in line with the water supply hole 43 formed on both sides of the connector 40, and the water flowing into the water pipe is flowed into the water pipe, the connector 40, and the filter. Water is purified by repeatedly passing through the cartridge 70 and the connector 40.

The purified water is stored in the reservoir along the hose (80).

As described above, the present invention can automatically shut off the valve in three steps when replacing the filter cartridge for the water purifier to prevent leakage of tap water to the outside when replacing the filter cartridge, so that anyone can easily replace the filter cartridge. There is one effect.
