On the contrary, when the moving cylinder 122 is lifted or lowered, the engagement between the second projecting end 124 and the second inner end 106 is slidably separated, so that the raw water, which has flowed into the inlet 102, The flow path that can flow into the cartridge 200 is opened.

That is, a method of allowing or blocking the flow of raw water introduced into the inlet 102 into the filter cartridge 200 in accordance with the driving of the moving cylinder 122 is applied.

It is preferable that at least one of the second projecting end portion 124 and the second inner end portion 106 has a seal-use material that can be elastically compressed and restored, and can have a watertight function. The reason for this is the same as the first protruding end portion 104 and the first inside end portion 210 described above, and thus will not be described here.

Further, the opening / closing control means 120 includes a ram 128 for opening / closing in addition to the moving cylinder 122.

The opening / closing control ram 128 is vertically installed at the inner center of the moving cylinder 122 and penetrates to the inner center of the outflow barrel 110.

The opening and closing control ram 128 has a rod shape having a uniform diameter in the longitudinal direction similar to the rod of the piston from the upper end to the body and the lower end portion 129 thereof is extended Sectional shape having a cross section. Due to the specific shape of the lower opening 129 of the opening / closing ram, the opening / closing adjusting ram 128 can more effectively open / close the lower opening 115 of the outflow barrel 110.

A damper 126 is interposed between the moving cylinder 122 and the opening / closing regulating ram 128.

Here, the damper 126 functions as the opening / closing control ram 128 when the opening / closing control ram 128 moves downward due to the downward movement of the moving cylinder 122, An instantaneous impact that is seated in the lower opening 115 may occur, which acts to attenuate such an impact. That is, the durability of the present embodiment can be improved by the damper 126.

In this embodiment, a coil spring having a metal or synthetic resin material is used as the damper 126, but this is merely an example, and the present invention is not necessarily limited thereto. That is, any elastic member capable of providing an impact damping effect to the opening / closing control ram 128 may be used in accordance with various embodiments.

Next, the plunger means 130 adjusts the upward and downward driving of the moving cylinder 122 among the above-mentioned opening and closing adjusting means 120. [

A plunger is a mechanical part formed to push and drive a mechanical device such as a piston. In the present embodiment, the flow of raw water into the filter cartridge 200 and the flow of purified water from the filter cartridge 200 are opened / The means for adjusting the upward and downward driving of the moving cylinder 122 through the pressing operation and the releasing operation is referred to as the plunger means 130 in order to adjust the temperature.

The plunger head 132 is a disc-shaped plate-shaped member and serves to receive a pressing operation from the top to the bottom in the plunger means 130 of the present embodiment.

The plunger elastic member 136 is a spring type member that is formed in contact with the lower portion of the plunger head 132 and is compressed or restored according to the pressing operation and the release of the plunger head 132.

This is because the plunger head 132 needs to have an elastic supporting force or an elastic restoring force of the plunger elastic body 136 in order to enable the pressing operation and the releasing by the button switch method. In this embodiment, a coil spring can be used as the plunger elastic member 136. Since the internal operation structure of the button switch system using the coil spring is the same as that of the conventional technology, the description thereof will be omitted.

The plunger pad 138 is a member that is formed in contact with the lower portion of the plunger elastic member 136 to form a bottom portion.

When the plunger head 132 is pushed and released, the plunger elastic body 136 is compressed and restored, and the plunger pad 138 is downwardly biased or released by a predetermined elastic force. As a result, the plunger pad 138 presses or releases the moving cylinder 122, so that the moving cylinder 122 moves up and down.

A first seal 113 having a watertight function is provided between the outfeed barrel 110 and the moving cylinder 122. The first seal 113 is provided between the outfeed barrel 110 and the moving cylinder 122, Another second seal 114 may be provided. In this embodiment, as shown in FIGS. 1 and 2, only one first seal 113 and one second seal 114 are used. However, the present invention is not limited thereto. Therefore, a larger number of seals may be additionally provided so as to enhance the watertight function.

Hereinafter, with reference to FIGS. 3 to 5, the process of separating the expired filter cartridge using the present embodiment will be briefly described as dividing into three operating states.

 [First operating state: intermediate stage of removing filter cartridge]

Fig. 3 is a first operating state view showing the operating state of the intermediate stage in which the filter cartridge is detached in this embodiment. Fig.

When the plunger means 130 is depressed to remove the expired filter cartridge 200, the moving cylinder 122 of the opening / closing control means 120 starts to descend. This state can be confirmed through FIG.

Since the filter cartridge 200 is not completely separated in the first operating state, the raw water introduced through the inlet 102 flows into the filter cartridge 200 and is purified, and the purified water flows out through the outlet 112 .

[2nd operating state: Completion of removal of the filter cartridge]

4 is a second operational state diagram illustrating the operational state of the step in which the filter cartridge is removed from the embodiment shown in Fig.

The moving cylinder 122 is driven to descend to the end by the pushing operation of the plunger means 130. [ As a result, the lower end 129 of the opening / closing control ram 128 closes the lower opening 115 of the outflow barrel 110, thereby completely interrupting the flow of purified water. This state can be confirmed through FIG.

In the second operation state, the moving cylinder 122 is engaged with the main body housing 110 to completely interrupt the flow of the raw water flowing from the inlet 102. This can prevent leakage.

On the other hand, the coupling between the main housing 100 and the filter cartridge 200 is separated, and at the same time, the coupling between the outflow barrel 110 and the filter cartridge 200 is separated. Thereby, preparation for coupling the new filter cartridge 200 is completed through the present embodiment.

[Separation of water in the third operating state filter cartridge]

Fig. 5 is a third operational state diagram illustrating the operating state of separately collecting water in the filter cartridge completely separated from the embodiment shown in Fig. 1. Fig.

The filter cartridge 200 separated from this embodiment can be recycled or discarded after separately collecting the water remaining therein. Thereafter, the new filter cartridge 200 can be combined using this embodiment to constantly receive the purified water from the raw water.

Up to this point, the operation states relating to the separation of the filter cartridges using this embodiment, which have been described with reference to Figs. 3 to 5, are the same as those in which the filter cartridges are assembled. Therefore, unnecessary repetitive description of the same contents will be omitted.

The preferred embodiments of the pressure-operated filter cartridge coupling device according to the present invention have been described above.

It is to be understood that the above-described embodiments are illustrative in all aspects and should not be construed as limiting, the scope of the invention being indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
