Description

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 can be used to easily understand the filter replacement time, so that the filter life of the filter life can be easily understood, and can be selectively replaced according to the need 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 to purify 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 provided with a filter body for filtering 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 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 water purifier used in the prior art is a pre-treatment filter that filters particles in the water through micro membranes such as nonwoven cells when raw water, which is tap water, is supplied to the inlet of the water purifier, and removes volatile organic substances in 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 precipitate filter, a pre-carbon filter, a membrane filter, and a post carbon filter are interpolated inside the filter body. As described above, since several types of filters are interpolated in one filter cartridge, the lifetimes of the filters located at the portion where raw water is drawn in and the portion where raw water is purified and drawn out are different.

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. Life is slower because raw water passes through when foreign substances and bacteria are filtered out several times.

However, as several filters are all interpolated inside a cartridge, the replacement of the filter requires replacing the entire filter cartridge in which several filters have been inserted. There is a problem, and even the filter that is still available can be replaced, so that the replacement cost of the filter cartridge is not small, which increases 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 to form a slope corresponding to the inclined recess toward the outside of the lower end to be bonded to each other by bonding each unit in the state in which the inclined protrusion is in contact with the inclined recess.

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 where a plurality of independently configured filters are stacked, and raw water is introduced through the main body and through the main body. Since the filtered water or soft water is configured to be withdrawn, there is a problem in that the body wraps 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. In addition, there is a problem that the management cost of the administrator is additionally generated because the managers who manage the filters professionally instead of the general consumers must visit and replace the filters.

Moreover, since the life of the filters stacked inside the body cannot be grasped by the naked eye at all, the administrator should visit and replace the filter periodically by setting a date, so that the filters that have not reached the end of their life are replaced as they are. There is this.

The present invention has been made to solve the problem of a filter that is composed of a plurality of components independently are combined with each other, the object of the present invention is to independently filter the filter body interpolated filters that perform different functions, respectively The raw water to be introduced can be filtered and purified, but the raw water supply body to which the win water is supplied to both sides of the filter body, which is independently configured, and the purified water extracting body through which the filtered purified water is drawn out, without a main body. The filter body can be installed and exposed to the outside, but the filter body is formed in a transparent body so that consumers can easily understand the filter life inside the filter body from the outside, so that the filter replacement time can be easily identified. Life of the filter body can be easily tightened and detached by screwing together. It is to provide a removable cartridge type filter that can be replaced by the customer only by separating the filter body can be replaced directly by the consumer can greatly reduce the maintenance cost.

The present invention is made in order to achieve the above object, the removable cartridge type filter of the present invention is a fastening piece formed in the inner bottom of the raw water supply fastening groove which is fastened to the front end of the raw water supply to which the raw water is supplied is formed on the inner bottom center and the upper outer peripheral surface Raw water inlet is formed in the first fastening projections; A pretreatment filter body having a first fastening groove which is screwed to the first fastening protrusion of the raw water inlet body and formed on a lower inner circumferential surface thereof, a second fastening protrusion on an upper outer circumferential surface thereof, and having a pretreatment filter interpolated therein and formed of a transparent material; A second fastening groove screwed into the second fastening protrusion of the pretreatment filter body is formed on the lower inner circumferential surface, and a third fastening protrusion is formed on the upper outer circumferential surface, and the calcium arsenite filter is interpolated therein and is formed of a transparent material.
