Removable cartridge filter {REMOVABLE CARTRIDGE TYPE FILTER}

The present invention relates to a detachable cartridge type filter, and more particularly, it is composed of a plurality of filter bodies so that incoming raw water can be filtered and purified, and each of the plurality of filter bodies is configured independently, and these filter bodies Can be easily fastened and separated by screwing each other, so that only the filter body that has reached the end of its life can be removed and replaced. The present invention relates to a detachable cartridge type filter which enables the filter life of the filter to be easily identified so that the filter replacement time can be easily known, and the filter can be selectively installed according to the needs of a plurality of filter bodies.

In general, although the water quality of treated tap water in the water treatment plant is quite good, it is not safe to drink tap water due to contamination such as bacteria caused by the change in water quality or the presence of deterioration factors in the process of supplying each household. A water purifier with a filter that cleans the raw water, which is supplied to the tap water, is installed or a filter body is installed in the raw water supply line.

These water purifiers are composed of a filter body for filtering the raw water therein, the conventional filter body has been developed and used to purify the water using a stone, such as carbide or gravel, or purifying by using an osmotic method.

However, the conventional water purifier filter using carbides or stones not only has a simple filtration effect, but also has a poor purification effect, so that the purified water cannot be relied on and drinkable. The purification filter using an osmotic method has a purification effect. Excellent, but also to clean the various various beneficial minerals contained in the water had a problem that can adversely affect the human body.

In addition, the filter body of the conventional water purifier is a pre-treatment filter for filtering particles in the water through the micro membranes such as nonwoven cells when the raw water is supplied to the inlet of the water purifier, and to remove volatile organic substances in the water through activated carbon Raw water is purified through an adsorption filter, an ion resin and sterilization or reverse osmosis.

The filter body of a water purifier which has been commonly used comprises a filter cartridge and a filter head to which the filter cartridge is mounted as one unit, and a sedimentation filter, a sun carbon filter, a membrane filter and a fu carbon filter are interpolated inside the filter body. As such, since several types of filters are interpolated in one filter cartridge, the lifespans of the filters located at the portion where raw water is drawn in and the portion where raw water is purified are drawn out differently.

In other words, the filter of the part where the raw water is drawn in has a long life because it continuously catches various foreign substances, bacteria, etc. contained in the raw water, and in the case of the filter where the raw water is purified and located in the part where the purified water is drawn out, it is included in the raw water. Life is slower because raw water passes through when foreign substances or bacteria are caught in several times.

However, since several filters are all interpolated inside a single cartridge, the replacement of the filter requires replacing the entire filter cartridge in which multiple filters have been inserted. There is a problem of bringing, even by replacing the filter can still be used is not a small replacement cost of the filter cartridge has a problem that adds to the cost of the consumer.

Accordingly, a plurality of filter cartridges have been constructed, in which a plurality of filter bodies are independently configured, and several independently configured filter bodies are fastened to each other.

For example, a water purifier cartridge filter has been devised, registered Utility Model No. 20-0301614, which combines an upper unit having a coupling screw portion at the top and a plurality of lower units stacked thereunder, each unit having granular activated carbon, In a cartridge filter that purifies water as it passes through the unit by incorporating a purifying material such as sand, the upper unit and the lower unit are inclined downward toward the outside so that the defective upper surface flows down without accumulating particles of the purifying material. It is configured to form an inclined recess to form, and to form an inclined protrusion forming an inclination corresponding to the inclined recess toward the outside of the lower end surface to be bonded to each other by bonding each unit in a state in which the inclined protrusion is in contact with the inclined recess.

As another example, a beauty water generator, which is registered utility model No. 20-0330418, has been conceived, which has a space for embedding raw water and a body equipped with a push button for discharging beauty water, and inside the body. It is inserted, and is formed of a plurality of filter cases are formed in the through hole through which the raw water is moved and separated / combined in multiple stages by the coupling means, and the filler is filled in the filter case to convert the raw water into functional beauty water.

These prior arts are composed of several types of filters that perform different functions, each independently, so that the various types of filters configured independently are fastened in multiple stages to filter raw water.

However, in the prior art, a separate main body for accommodating the stacked filters therein is further configured in a state in which a plurality of independently configured filters are laminated, and raw water is introduced through the main body and is also provided through the main body. Since the filtered water or soft water is configured to be drawn out, the main body wraps around the outside of a plurality of stacked filters, so that consumers cannot grasp the life of the filter with the naked eye.

In addition, even if the filter is selected and replaced at the end of its life, first, the main body must be removed to remove the filter contained in the main body, and after replacement, the main assembly must be assembled again to accommodate the filter inside the main body, thereby making the replacement difficult. However, there is a problem in that the management cost of the administrator is additionally generated because the managers who manage the filters professionally, rather than the general soba, must visit and replace the filters.

Moreover, since the life of the filters stacked inside the main body cannot be grasped by the naked eye at all, the administrator should visit and replace the filters periodically by setting a date. have.

The present invention has been made to solve the problem of the filter is composed of a number of independently configured, they are combined with each other. It is possible to be purified, but further comprises a raw water supply to each side of the filter body that is independently configured to be supplied with a water supply, and a purified water extracting body from which the filtered purified water is drawn can be installed without the main body and the filter body is external Exposed to the filter body, the filter body formed of a transparent body so that consumers can easily determine the filter life inside the filter body from the outside, so that it is easy to determine the replacement time of the filter, as well as screwing the filter body with each other It is easy to fasten and detach by using It is an object of the present invention to provide a removable cartridge type filter which can be replaced by a consumer, thereby making it possible to significantly reduce maintenance costs.
