Referring to FIGS. 1-4, an adapter 100 according to an embodiment of the present invention is a one-touch assembly adapter 100, which allows a filter assembly formed with a cylindrical channel with an annular flange at one end to be detachably connected to the adapter. Connector 100 fits.

The one-touch assembled adapter 100 of the present invention includes: an adapter body 10, which is formed with an inlet 10in on both sides of its upper part, a source water inlet hole 10c, a purified water outlet hole 10d, and a purified water outlet 10out, and a central channel communicating with the above-mentioned inlet, outlet, inlet and outlet is formed in its center; a one-way valve 20 is installed in the central channel so as to regulate the inflow or the source water flowing through the inlet 10in Cut off; the upper cover 10a for covering the upper part of the central channel; the lower cover 10b, which is installed on the lower part of the adapter body 10, so that the lower cover 10b communicates with the central channel; side plates 50A and 50B, which are installed On the lower cover 10b and can move relative to each other, so as to detachably assemble the filter assembly on the adapter 100; and the separation knob unit 40, which is used to release the assembled state between the side plates 50A and 50B and the filter assembly, So separate them.

The one-way valve 20 includes: a valve body having an inclined seat surface 20f and communicating with the inlet 10in; a fluid channel 20a extending from the valve body to the lower part of the central passage; The plunger head in the fluid channel 20a makes when the filter assembly is assembled with the adapter or the filter assembly is removed from the adapter, the valve plunger 20c can be placed in the fluid channel 20a by the pressure applied from the filter assembly. middle movement, while the valve plunger 20c can open/close the fluid passage 20a; and the valve spring 20d, which is supported by the upper cover 10a, and which elastically biases the plunger head mounted on the inclined seat surface 20f of the valve body.

The plunger head of the valve plunger 20c is provided with an O-ring 20e to seal the gap between the plunger head and the inclined seat surface 20f.

A source water channel 20b is formed in the fluid channel 20a so that source water is supplied from an inlet 20in through the source water channel 20b. The valve plunger 20c includes a plunger head provided with an O-ring 20e, and it is subjected to the elastic biasing force of the valve spring 20d supported by the upper cover 10a, so as long as no external force is applied to the plunger head of the valve plunger 20c, the valve The plunger head of the plunger 20c is in close contact with the inclined seat surface of the valve body.

According to one embodiment of the present invention, a reverse flow preventing valve 30 (ie, a one-way valve) is installed in the purified water outlet 10out of the converter main body 1, so as to prevent the residual purified water remaining in the rear of the purified water outlet 10out from flowing from the purified water to the purified water outlet 10out. Outlet 10out reverse flow or drop.

The side plates 50A and 50B have oblique elongated holes 50a and 50b facing each other; and opposite arcuate portions 51a and 51b for detachably making the ring provided at the inlet portion of the filter assembly The shaped flange (215, see FIG. 5) is connected with the adapter 100. The side plates 50A and 50B are biased against each other by springs mounted on the spring mounting protrusions 50s. The ends of the arcuate portions 51a and 51b in the side plates 50A and 50B are formed with inclined portions (see 51b' in FIG. 4 ) to allow the filter assembly to easily fit with the arcuate portions 51a and 51b while being able to move along the inclined portions.

Therefore, when the filter assembly 200 is assembled with the adapter 100, while the side plates 50A and 50B are moved horizontally in the left-right direction, the annular flange 215 provided at the inlet portion of the filter assembly is moved along the side plate 50A. The inclined portions 51b' of the arcuate portions 51a and 51b in the and 50B move upward. When the annular flange 215 moves upward beyond the inclined portion 51b' of the arc portion 51a and 51b in the side plates 50A and 50B, the side plates 50A and 50B can return to their original positions by the biasing force of the spring S, so that the filter assembly Mates with side panels 50A and 50B.

The separation knob unit 40 includes two parallel rods formed with protrusions 40a inserted into inclined elongated holes 50a and 50b, and a horizontal push rod connecting ends of the parallel rods to each other. When the filter assembly 200 needs to be detached from the adapter 100 , the user pushes the separation knob unit 40 so that the separation knob unit 40 moves forward. At this time, the protrusion 40a inserted into the inclined long holes 50a and 50b of the side plates 50A and 50B moves forward along the inclined long holes 50a and 50b while contacting the side walls of the inclined long holes 50a and 50b, so that the side The plates 50A and 50B move horizontally in the left-right direction perpendicular to the moving direction of the projection 40 a of the separation knob unit 40 . As a result, side plates 50A and 50B move away from each other, enabling removal of filter assembly 200 from adapter 100 .

The horizontal push rod of the separation knob unit 40 is formed with a mounting hole 45 for a safety pin for preventing the push rod from being pushed to prevent accidental separation of the filter assembly 200 from the adapter 100 .

According to another aspect of the present invention, the filter assembly 200 is detachably mated with the one-touch assembly adapter 100 shown in FIG. 1 .

Figure 5 shows a filter assembly 200 according to one embodiment of the present invention.

As shown in FIG. 5 , the filter assembly 200 includes: a housing 210 formed with a cylindrical fluid passage at its inlet portion, wherein the cylindrical fluid passage has an annular flange; separated from the inner wall of the housing 210 and installed in the housing and a water guide 220, which is installed between the upper end of the filter 240 and the cylindrical fluid channel 200a of the housing 210 to guide the water through the one-way valve of the one-touch assembled adapter 100 When introduced there, water can be guided to the filter element 240 , and it can guide the water purified by the filter element 240 into the purified water outlet 10out of the one-touch assembled adapter 100 . The water guide 220 includes: an annular partition wall 220a, which forms an inflow passage of the source water through the one-way valve and is used to prevent the source water from mixing with the purified water; Guided into the flow space formed between the side wall of the filter element and the inner wall of the housing; the purified water outflow channel 220c installed on the upper side of the filter element, which is used to introduce water from the inflow space and purified by the filter element through the partition and a push rod 220d installed in the inner central portion of the annular partition wall 220a so as to open the check valve while in contact with the valve plunger 20c of the check valve. As a result, the source water is guided from the one-way valve to the flow space through the inflow channel of the partition wall, and while flowing from the lower part of the filter member to its upper part, the filter member filters the source water and passes through the purified water outflow channel 220c, Drain it to the outside (ie water flows in the direction of the arrow as shown in Figure 8).

The filter element 240 includes at least one filter selected from hollow fiber filters, non-woven filters, activated carbon filters, reverse osmosis membrane filters and functional ceramic filters. One of the above-mentioned filter elements or at least two of the above-mentioned filter elements may form a filter assembly.

6-9 illustrate a method for installing or removing the filter assembly 200 into or from the one-touch fit adapter 100 .

FIG. 6 shows the adapter shown in FIG. 1 and the filter assembly shown in FIG. 5 separated from each other according to one embodiment of the present invention.

In a state where the adapter and the filter assembly are separated from each other as shown in FIG. 6 , the side plates 50A and 50B of the adapter 100 are biased so that they are brought into contact with each other by the spring. In addition, the protrusion 40a of the separation knob unit 40 inserted into the inclined long holes 50a and 50b is located at the starting point of the inclined long holes 50a and 50b (ie, the lower part in plan view shown in FIG. 8 ).

In addition, since the check valve 20 mounted in the central passage of the adapter is biased downward by the valve spring 20d, the O-ring 20e closely contacts the inclined seat surface 20f formed in the valve body 20a, so that the valve body 20a passes The O-ring 20e closes the source water passage, thereby cutting off the inflow of the source water.

Figure 7 shows the adapter shown in Figure 1 and the filter assembly shown in Figure 5 just before the filter assembly is loaded into the adapter according to an embodiment of the present invention; Figure 8 shows a filter assembly according to the present invention Embodiment The adapter shown in FIG. 1 and the filter assembly shown in FIG. 5 when assembled with each other.

The filter assembly 200 is loaded into the adapter 100 through the following process.

First, if the user pushes the filter assembly 200 upward into the central passage hole formed at the lower portion of the adapter 100, the annular flange 215 provided at the upper side inlet portion of the casing 210 of the filter assembly 200 moves upward, At the same time, it is in contact with the inclined portions 51a' and 51b' of the arcuate portions 51a and 51b in the side plates 50A and 50B.

Therefore, the side plates 50A and 50B move away from each other. At the same time, the protrusion 40a inserted into the inclined long holes 50a and 50b moves along the inclined long holes 50a and 50b. At this time, as shown in FIG. 7, the protrusion 40a inserted into the inclined long holes 50a and 50b is located in the middle of the inclined long holes 50a and 50b.

At this time, the adapter 100 and the filter assembly 200 remain sealed. In detail, FIG. 7 shows just before the filter assembly 200 is assembled with the adapter 100 (that is, just installed at the inner central portion of the annular partition wall 220a formed at the front end of the water guide 220). The push rod 220d pushes the filter assembly 200 installed in the fluid channel 20a of the check valve (in front of the lower end of the valve plunger 20c). Therefore, the O-ring 20e of the valve plunger 20c is still in contact with the inclined seat surface 20f of the valve body, so that the source water passage 20b is kept in a closed state by the O-ring 20e of the valve plunger 20c. At the same time, the O-ring 20g installed at the lower end of the water flow channel 20a to prevent source water from leaking is in contact with the inner surface of the ring-shaped partition wall 220a installed in the filter assembly 200 to prevent the source water from mixing with the purified water, thereby connecting the water flow channel 20a with the ring. Sealing is achieved between the partition walls 220a. In addition, at least one O-ring 230 is installed around the cylindrical channel provided at the front end of the filter assembly to prevent the purified water from leaking. The O-ring 230 contacts the inner surface of the central channel of the adapter 100 to achieve a seal between the filter assembly and the adapter. Therefore, the source water channel is provided independently of the purified water channel. In addition, purified water is kept in fluid passages formed in the filter assembly and the adapter so as not to leak outward.

Once the annular flange 215 moves upward beyond the sloped portions 51a' and 51b' of the side plates 50A and 50B, the springs S bias the side plates 50A and 50B in opposite directions to each other so that the side plates 50A and 50B move relative to each other, The annular flange is thus bounded by side panels 50A and 50B. As a result, the filter assembly 200 is assembled with the adapter 100 .

At this time, since the protrusions 40 a inserted into the inclined long holes 50 a and 50 b of the side plates 50A and 50B slide forward, the separation knob unit 40 pops out right in front of the adapter 100 . At this time, as shown in FIG. 8, the protrusions 40a inserted into the inclined long holes 50a and 50b of the side plates 50A and 50B are slightly separated from the lower ends of the inclined long holes 50a and 50b.

When the filter assembly 200 is assembled with the adapter 100, the push rod 220d of the filter assembly 200 can push up the valve plunger 20c of the one-way valve 20 installed in the adapter 100, so that the valve plunger 20c that is in contact with the inclined seat surface 20f The O-ring 20e is separated from the inclined seating surface 20f so that the source water passage 20b is opened. Since the one-way valve 20 communicates with the inlet 10in of the adapter body 10, if the one-way valve 20 is opened, the source water flowing through the inlet 10in of the adapter body 10 can pass through the hole formed in the center of the one-way valve. The source water channel 20b of the fluid channel 20a flows into the annular partition wall 220a of the water guide 220 .

As shown in FIG. 8 , an annular partition wall 220a and an O-ring 20g installed at the front end of the water guide 220 between the filter and the inlet can prevent the source water and purified water introduced into the filter assembly from mixing. In addition, the source water flows through the flow space between the inner wall of the housing 210 and the side wall of the filter member 240 while passing through the source water passage switching channel 220b. Then, the source water is filtered while flowing through the filter member 240, and flows upward. Therefore, the source water filtered by the filter element 240 can flow into the space defined by the outer surface of the annular partition wall 220a, the outer surface of the fluid channel 20a of the one-way valve and the inner surface of the neck formed at the front end of the filter assembly. Then, the purified water is discharged to the outside through the purified water space 10e, the purified water outlet hole 10d, and the purified water outlet 10out. As a result, the water flows along the paths shown according to the directions of the arrows in the drawings.

When the filter assembly and the adapter have been installed together, the safety pin is inserted into the safety pin installation hole 45 of the separation knob unit 40 so that the separation knob unit 40 cannot move, thereby preventing the filter assembly from being separated from the adapter accidentally.

FIG. 9 shows a method for disassembling the filter assembly shown in FIG. 5 from the adapter shown in FIG. 1 in the assembled state shown in FIG. 8 according to an embodiment of the present invention.

If the filter assembly 200 must be replaced from the adapter, the user should remove the safety pin from the detachment knob unit 40 and push the detachment knob unit 40 .

If the user pushes the separation knob unit 40 , the separation knob unit 40 moves forward together with the protrusion 40 a fixed on the separation knob unit 40 . Since the protrusion 40a is inserted into the inclined slots 50a and 50b of the side plates 50A and 50B, forward movement of the protrusion moves the side plates 50A and 50B away from each other. Therefore, the side plates 50A and 50B holding the annular flange 215 of the filter assembly can move in the left and right directions opposite to each other, so that the filter assembly can be separated from the adapter. At this time, the pressure applied to the push rod 220d on the valve plunger 20c is released, so that the valve plunger 20c is moved downward by the biasing force of the valve spring 20d. Therefore, the O-ring 20e of the valve plunger comes into close contact with the inclined seat surface 20f of the valve body, thereby cutting off the inflow of source water.

In addition, according to another embodiment of the present invention, an improved structure of the adapter 100 and the filter assembly 200 matched with the adapter 100 is provided.

The improved structure of the present invention achieves the above-mentioned effects of the above embodiments without using a side plate for connecting the filter assembly with the adapter and a separate knob unit for separating the filter assembly from the adapter.

As shown in Figures 10-12, although the adapter 100' of one embodiment of the present invention does not have side plates and separate knob units, it is provided with part of the peripheral edge 15a, and these edges are arranged opposite to the outer peripheral portion of the central hole 15 of the lower cover. .

In addition, according to an embodiment of the present invention, as shown in FIGS. 13 and 14 , a filter assembly 200' is provided having an opposite partially arc-shaped annular flange 215', wherein the annular flange is disposed on the filter assembly formed on The exterior of the cylindrical fluid channel at the inlet portion of the filter assembly 200' can be matched with the adapter 100'.

Therefore, when the filter assembly 200' is mated with the adapter 100', the cylindrical fluid channel of the filter assembly 200' is inserted into the central hole 15 of the lower cover. At this time, in the state where the adapter 100' is separated from the filter assembly 200' as shown in FIG. The flange 215' matches the central hole 15 of the lower cover. Afterwards, as shown in FIG. 12 , the adapter body and the filter assembly are relatively rotated so that a part of the arc-shaped annular flange 215' is formed along a part of the circumferential edge 15a at the central hole 15 of the lower cover of the adapter 100'. movement, so that the filter assembly 200' is connected to the adapter 100' through the partial screw fit between them.

Therefore, when the filter assembly 200' is rotated relative to the adapter 100', the peripheral edge 15a formed in the central hole 15 of the lower cover contacts the inclined portion 215a' of the partially arc-shaped annular flange 215'. Therefore, due to the action of the inclined portion 215a', the upward bias is applied to the horizontal rotational force on the inclined portion 215a' of the partially arc-shaped annular flange 215', so that the filter assembly 200' is easy to move while moving along the inclined portion. upward movement. At the same time, the partially arc-shaped annular flange 215' can move smoothly along the peripheral edge 15a so as to connect the filter assembly 200' with the adapter 100'.

In addition, the inclined portions 215a' formed at the partially arc-shaped annular flange 215' arranged opposite to each other have the same orientation. The circumferential edge is preferably provided on its other end with a stop projection 15b so that when the partially arcuate annular flange has reached the connected position by moving along the circumferential edge 15a, the partially arcuate annular flange cannot move further.

The other features and connection functions of the adapter 100' and the filter assembly 200' are basically the same as those of the above adapter and filter assembly, so their detailed description will be omitted below.

According to another aspect of the present invention, a multi-adapter for mating with a plurality of filter assemblies 200a, 200b, 200c, 200d, and 200e is provided. Figure 15 shows this duplex adapter.

In products incorporating multiple filter components (such as water purifiers or water ionizers), each filter component has its own function and life, so when the life of the filter component is exhausted, the filter component can be replaced selectively . At this time, during the replacement work of the filter assembly, the source water must be cut off and no longer flow in.

However, since the check valve 20 is included in the multi adapter of the present invention, no additional work of cutting off the inflow of source water is required during the replacement work of the filter assembly. That is, according to the present invention, the user can easily replace the old filter assembly with the new filter assembly by separating the old filter assembly from the adapter and connecting the new filter assembly to the adapter when pushing the separation knob unit. filter components. Additionally, the old filter assembly is detached from the adapter by rotating the old filter assembly relative to the adapter and the new filter assembly is connected to the adapter by rotating the new filter assembly relative to the adapter , can easily replace the filter unit.

Preferably, the gap formed between the outer peripheral surface of the plug connector 150 and the inner peripheral surfaces of the inlet and outlet is sealed by an O-ring. In addition, each single adapter of the multi-type adapter can be rotated around the plug connector, so that the lower cover 10b installed at the lower part of the adapter body 10 can be rotated toward the user, so the user can easily and conveniently Carry out filter replacement work.

Furthermore, the present invention relates not only to a one-touch assembly single or multiple adapter, but also to a water purification system equipped with at least one filter assembly. That is, the one-touch fit single or multiple adapters and filter assemblies that removably mate with the one-touch fit single or multiple adapters can be used as part of various water purification systems. Accordingly, the present invention includes these water purification systems.
