Assembly structure of filter for water purifier {ASSEMBLY STRUCTURE OF A WATER PURIFIER FILTER}

The present invention relates to a filter for a water purifier, and more particularly, to a simple structure of the head coupled to the body of the water purifier and an assembly structure of the filter for water purifiers that can completely block the leakage of the connection portion.

Typically, the water purifiers are connected to each other in parallel in the water purifier while having a structure of several stages such as activated carbon, ceramics, and zeolites. Therefore, the water injected into the water purifier passes through each filter to filter foreign substances and heavy metals contained in the water and to obtain clean purified water.

On the other hand, the filter loses its function as foreign matter accumulates, and needs to be replaced regularly. For this purpose, the filter has a head that is separated from the top of the body. Such a conventional filter structure has a drain passage 14 in the center of the body 10 into which the filter 50 is inserted, as shown in FIG. 1, and has a predetermined inlet hole 16 along its circumference. In addition, the head 20 'assembled on the upper portion of the body 10 has an inflow passage 22 formed therein while an inflow pipe 22' is formed at the center thereof, and a drain passage 42 is formed at the center thereof. An excitation insert 40 is inserted, and a cap 46 for fixing the insert is assembled thereon. Thereafter, tap water is supplied to the inlet hose 28 connected to the inlet passage 44 and is injected into the filter 50 through the inlet hole 16 of the body. In addition, the filtered water is discharged to the drain hose 29 connected to the outside through the drain passage 14 of the body 10 and the drain passage 42 of the insert.

However, such a conventional filter assembly is not only complicated in structure, but also increases the manufacturing cost due to the increase in the number of parts to be assembled. In addition, although the packing ring 36 is fitted in the contact portion between the head and the body, in particular, the contact portion between the inflow pipe 22 'and the upper surface of the body, the sealing force is weak, so that the leakage may occur. In addition, a plurality of o-rings 48 and 49 are inevitably provided. This also increases the manufacturing cost due to the increase in the number of parts and the assembly process.

The present invention is to overcome the above-mentioned problems in the prior art, the object of the present invention is to reduce the manufacturing cost as the head is assembled with the body of the water purifier integrally, it can have a perfect leakage blocking effect by a minimum sealing means An assembly structure of a filter for a water purifier is provided.

In order to achieve the above object, the present invention provides a filter for a water purifier having a body into which a filter is inserted and a head assembled with the body, wherein the head comprises a first inlet pipe having a drain passage 23 formed at the center thereof. 22, the second inlet pipe 24 to form an inlet passage 25 to the outside of the inlet pipe, and the screw coupling portion 26 is formed integrally with the body while being formed outside the second inlet pipe. The packing ring 30 is provided between the second inlet pipe 24 and the upper surface of the body 10.

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

First, in describing the present invention, if a detailed description of a related known function or configuration may obscure the subject matter of the present invention, the detailed description thereof will be omitted.

2 and 3 show the configuration of the assembly structure of the water filter according to a preferred embodiment of the present invention.

According to the drawings, the assembly structure of the filter for the water purifier of the present invention is a head having a body (10) into which the filter is inserted therein, and a means for assembling and supplying water and discharging the purified water to an upper portion of the body ( 20).

The above is described in more detail as follows.

First, the induction part 12 protruding from the center is formed on the upper portion of the body 10 into which the conventional filter 18 is inserted. In addition, a drain passage 14 is formed at the center of the induction part 12 to the inside of the filter 18, and predetermined inlet holes 16 are disposed at regular intervals outside the drain passage 14. have. And the packing ring 30 is fitted to the outside of the guide portion 12, the screw coupling portion 18 is formed on the outside.

Meanwhile, the head 20 coupled to the upper portion of the body 10 may include a first inflow pipe 22 having a drain passage 23 formed at the center thereof, and a second inflow path 25 formed outside the inflow pipe. The inlet pipe 24 and the screw coupling part 26 which is formed outside the second inlet pipe and coupled to the body 10 are integrally formed. That is, while the lower end of the first inlet pipe 22 is in close contact with the upper surface of the guide portion 12 of the body 10, the drain passage 23 is connected to the drain passage 14 of the body, the inflow passage (outside) 25 is passed through the inlet 16 of the body. And the outer screw coupling portion 26 is coupled to the screw coupling portion 18 formed on the lower body 10 to be disassembled and assembled. The upper portion of the inflow passage 25 communicates with the inlet hose 28 connected to the outside while forming a predetermined space portion, and the external drainage hose 23 forms a predetermined space portion thereon in the central drain passage 23. 29). Therefore, the water flowing through the inlet hose 28 is introduced into the filter 50 through the inlet passage 25 and the inlet hole 26, and the water purified by the filter is the drain passage 14, 23 of the center. To the drain hose.

At this time, the packing ring between the lower portion of the second inlet tube 24 and the upper surface of the body 10 in order to prevent the water flowing into the inflow passage 25 from leaking through the lower portion of the second inlet tube 24 on the outside. 30 is fitted.

Meanwhile, at the lower end of the second inflow pipe 24, a protruding frame 32 is formed to press the upper surface of the packing ring 30, and protrudes downward along the outer edge to fix the packing ring 34. It is provided. The protruding frame 32 protrudes downward as a circle formed along the second inflow pipe 24, and preferably has a lower portion of the cross section pointed like an inverted triangle.

Referring to the operation of the assembly structure of the present invention water filter configured as described above are as follows.

First, when the head 20 is coupled onto the body 10, as the protruding frame 32 formed below the second inlet pipe 24 presses the upper surface of the packing ring 30 sandwiched between the bodies, the above Pointed projecting frame 32 is penetrated into the packing ring 30 and the flexible packing ring 30 is raised close to the projecting frame while being strongly adhered to the outside of the projecting frame. This maintains perfect airtightness between the second inlet pipe 24 and the body.

Then, the filter assembly is continuously connected to the filter assembly through the inlet hose and the drain hose is mounted into the case of the water purifier, the water injected into the inlet hose 28 is the inlet passage 25 and the inlet hole 16 Through the filter 50 is introduced into the purified water. Thereafter, the purified water is discharged to the drain hose through the central drain passages 14 and 23, and then filtered again by another filter assembly or used as drinking water through the discharge port.

As described above, the assembly structure of the filter for water purifiers according to the present invention can be produced integrally without the parts to be assembled inside the structure of the head coupled to the body can reduce the production cost, the labor cost of the reduction of the assembly process There is an economic effect to prevent consumption. In particular, the filter inlet 34, which is secured so as not to be pushed outwardly while being in close contact with the packing ring while being tightly in contact with the packing ring fitted to prevent leakage, is completely blocked. It does not require multiple o-rings.
