The present invention relates to an automatic locking structure of a water softener filter, and more particularly, a filter for a water softener filter is automatically locked in conjunction with a tank stopper only by locking a stopper of an ion resin tank without separately locking the water softener filter. It relates to a self-locking structure.

In general, tap water and groundwater contain various kinds of impurities, and representative impurities include ionic substances such as potassium, magnesium, sodium, bicarbonate, sulfuric acid, chlorine, silicon dioxide, iron, and manganese. Containing water is called hard water.

Ionic substances contained in hard water are beneficial to the body, but most of them have adverse effects such as promoting aging of the skin.

In particular, tap water contains a large amount of chlorine components used in the purification process, and contaminated surface water flows into the household through the aged pipes, which causes harmful effects on iron, lead, zinc, Various heavy metals, such as mercury, are included.

The ionic materials and heavy metals cause various skin diseases or promote skin aging. To prevent this, tap water is passed through a Na (+)-type strong acid cation exchange resin, and Ca (+2), which is a hardness component contained in water, ) And Mg (+2) ions are developed for soft water by exchanging Na (+) ions in ionic resin to soft water.

1 is a view showing the structure of a conventional water softener, FIG. 2 is an exploded perspective view showing a filter and a tank cap inserted into an ion resin tank inlet of a conventional water softener, and FIG. 3 is a view illustrating a locking structure of a conventional water softener filter. This is a state diagram.

First, referring to Figures 1 and 2 briefly describe the conventional process of tap water and the locking structure of the conventional water softener filter as follows.

Tap water supplied to each home through a water pipe (hereinafter referred to as “raw water”) is introduced into the ion resin tank 2 in which the ion resin is stored through the raw water supply pipe 3, and the raw water is supplied to the ion resin tank ( While passing through 2) is converted into soft water through the ion exchange process as described above, the soft water is discharged back to the faucet 5 installed in each home through the soft water pipe (4).

The ion resin tank 2 is filled with an ion resin 6 for converting raw water into soft water, and an inlet 1 provided at an upper portion of the ion resin tank 2 to filter impurities contained in raw water. 10 is installed.

The filter 10 is inserted through the inlet part 1 and mounted inside the inlet part 1 to filter impurities or suspended matter contained in the raw water introduced through the raw water supply pipe 3 to the primary. When the filter 10 is used for a certain period of time, the performance deteriorates and the filter 10 needs to be replaced with another filter. When the filter 10 is replaced with a new one, the filter 10 is taken out again through the inlet 1 and replaced with a new one.

In this way, the raw water passes through the filter 10 in the upper portion of the ion resin tank 2 and flows back to the lower ion resin 6 in a state where impurities are filtered, so that the raw water and the ion resin are in the ion resin tank 2. The raw water is converted into soft water through an ion exchange process as it is mixed together within.

On the other hand, the inlet portion 1 provided in the upper portion of the ion resin tank (2) is normally closed the ion resin tank (2) when the ion resin tank (2) needs to be opened, that is, to replace the filter 10 or The tank stopper 20 is detachably installed at the inlet 1 in case of filling the ion resin 6.

Since the ion resin tank 2 is filled with ion resin and raw water, a very high internal pressure is formed in the ion resin tank 2 in a sealed state. The tank stopper 20 and the filter 10 are completely closed. If it is not locked, the filter 20 may suddenly rise upward through the inlet 1 due to the internal pressure of the tank, which may cause an accident.

Therefore, as shown in FIG. 2, the filter 10 and the tank stopper 20 should have a structure that can be locked to the inlet 1 of the ion resin tank 2, where the conventional filter 10 A filtration unit 11 for filtering impurities contained in raw water is provided, and a head unit 12 is provided at an upper portion of the filtration unit 12, and the inlet unit 1 is formed on the circumference of the head unit 12. The locking protrusion 12a is formed to protrude.

In addition, the upper surface of the head 12, the filter 10 is inserted into the inlet 1, the hand to turn the hand or to easily pull out from the inlet 1 when replacing the filter 10 The catching part 13 is provided.

On the other hand, when the filter 10 is inserted into the inlet (1) is provided with a tank stopper 20 for blocking the inlet (1) to protect the filter 10 from the outside, the tank stopper 20 Is disposed above the filter 10 mounted on the inlet part 1 is locked to the inlet part 1 to prevent the water or ion resin inside the filter 10 and the tank from flowing out by the internal pressure of the tank.

The tank stopper 20 has an insertion part 21 inserted into the inlet part 1 to protrude, and the tank stopper 20 is caught on the inlet part 1 on the outer circumference of the insertion part 21. A locking projection 21a is formed to be locked.

In addition, the inlet part 1 is provided with a guide part 7 having a locking step 7a formed to catch the filter locking protrusion 12a and the tank plug locking protrusion 21a.

Here, in order to lock the filter 10 and the tank stopper 20, as shown in FIG. 3, the user inserts the filter 10 into the inlet 1 of the ion resin tank 2 first, and then the user selects the filter ( Rotating the handle 13 in the upper portion of the 10 to be caught by the locking jaw (7a) provided in the inlet (1), and then rotating the tank stopper 20, the stopper (21a) of the tank stopper Is locked to the engaging jaw (7a) of the inlet (1) while maintaining the same state as (a).

However, in most cases, a user using a water softener forgets to lock the filter 10 after the filter 10 is inserted into the inlet 1, and only rotates the tank stopper 20 to lock it. The locking protrusion 21a of the lock is locked but the locking protrusion 12a of the filter is used in an unlocked state.

Of course, since the upper tank stopper 20 blocks the filter 10 even in the state as shown in (b), even if the internal pressure of the ion resin tank 2 is high while the tank stopper 20 is closed, the filter 10 The filter 10, which is not able to rise up, but opens the tank stopper 20 as shown in (c), rises up by internal pressure and injures the user who opened the tank stopper 20, causing injury or by sudden release of the pressure. The problem that the ion resin and water in the tank are eluted out together and outflows frequently occurs frequently.

The present invention has been proposed to solve the above problems, the object of the present invention is to provide an automatic locking structure of the water softener filter, the filter is locked only in conjunction with the tank stopper, even if the user forgets to lock the filter, only the tank stopper, This is to solve the conventional problem of suddenly eluting a filter which is not locked when opening the tank cap.

The present invention for achieving the above object, the ion resin tank having an inlet, a filter entering and exiting through the inlet and mounted on the inside of the inlet, and the upper portion of the filter while being detachable to the inlet In the water softener with a tank stopper to be installed,

The upper portion of the filter has a rod-shaped moment portion protruding toward the tank stopper, the bottom of the tank stopper with a triangular protrusion for transmitting rotational force to the moment only when the tank stopper is locked to each other based on the center of the tank stopper Characterized in that formed facing.

In addition, the protrusion is characterized in that at least one side is formed in parallel with the moment portion.

In addition, the protrusion is characterized in that the end angle toward the moment portion is a right angle.

In addition, the moment portion is characterized in that the opening is formed to be easily caught.

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated in detail based on attached drawing.

Figure 4 is a perspective view showing a filter according to the filter automatic locking structure of the present invention, Figure 5 is a perspective view showing the structure of the tank stopper according to the present invention, Figure 6 illustrates the interlocking operation of the tank stopper and the filter according to the present invention. 7 is an operational state diagram for showing an interlocking state of the filter and the tank stopper according to each operation of FIG. 6.

First, as shown in FIG. 4, the filter 30 according to the present invention is provided with a filtration part 31 for filtering impurities contained in raw water, and a head part 32 is provided at an upper side of the filtration part 31. do.

In addition, on the circumference of the head portion 32, a catching protrusion 32a is formed to protrude from the inlet portion 1 of the ion resin tank so as to lock the filter 30, and the upper portion of the filter 30, that is, the head The upper surface of the portion 32 is provided with a moment portion 33 having a predetermined height in order to provide an automatic locking structure of the filter for water softener according to the present invention.

The moment part 33 is rotated on the inlet 1 of the ion resin tank (2) by rotating the filter 30 when the external force is applied to the locking projection (32a) provided on the circumference of the filter 30 The hooking jaw (7a) provided in the inlet (1) to be caught.

At this time, the moment portion 33 is formed to protrude toward the bottom side of the tank stopper 40, the height of the tank stopper 40 should be close enough to reach the bottom.

In addition, the moment portion 33 is preferably configured so that the flat cross-section is in the shape of a rod to facilitate the rotation of the filter 30, when the filter 30 is replaced at the inlet portion (1) The opening 33a may be formed at the center so that the lifter can easily lift and lift the lifter.

On the other hand, as shown in Figure 5, the tank stopper 40 is provided with an insertion portion 41 for insertion into the inlet portion 1, the circumference of the insertion portion 41 of the inlet portion (1) A catching protrusion 41a is provided to catch the catching jaw 7a so that the tank stopper 40 is locked to the inlet 1.

In addition, the bottom of the tank stopper 40 is provided with a projection 42 for transmitting a rotational force to the moment portion 33 of the filter 30, the projection 42 is in contact with the moment portion 33 As long as the position is possible, the insertion part 41 may be provided on the bottom surface, and as shown in FIG. 5, if the insertion part 41 has a hollow shape, the insertion part 41 may be located on the bottom surface of the tank stopper 40. This can be appropriately changed according to the needs of the practitioner.

Here, the protrusion part 42 transmits a rotational force to the moment part 33 only when the tank stopper 40 is rotated in the locking direction, and when the tank stopper 40 is rotated in the opening direction, the moment part ( 33) it must not be capable of transmitting any force.

Thus, the protrusion 42 is provided at positions symmetrical with respect to the center of the tank stopper 40 as shown, the overall shape is a right triangle, the vertex portion (p) toward the moment portion 33 is It is preferable that it is comprised at right angles.

In addition, one side of the two sides forming the right angle is configured to be parallel to the moment portion 33 having a rod shape, the other side is configured to be perpendicular to the moment portion 33.

When the filter 30 and the tank stopper 40 having the moment part 33 and the protrusion part 42 are inserted into the inlet part 1 of the ion resin tank 2, the moment part 33 and the protrusion part 42 are provided. ) Are met in the state shown in FIG.

6 (a) is a state in which the tank cap 40 is positioned on the filter 30 in a state in which the filter 30 is inserted into the inlet 1 and is not locked.

This state is the same as that shown in Fig. 7A. In this state, both the locking projection 32a of the filter 30 and the locking projection 41a of the tank cap are not locked.

In this case, when the tank stopper 40 is rotated to the locked position, the protrusion 42 integrated with the tank stopper 40 contacts the moment part 33 and transmits a rotational force to FIG. Likewise, the moment part 33 is rotated in the same direction as the rotational direction of the tank stopper 40, and at this time, the filter 30 integrated with the moment part 33 is also the same as the turning angle of the moment part 33. As shown in FIG. 7B, the locking projection 32a of the filter and the locking projection 41a of the tank cap are both formed at the inlet 1 of the ion resin tank 2 as shown in FIG. 7a) is locked.

On the other hand, when the tank stopper 40 is rotated to the open position in this state, as shown in Figure 6 (c) at this time the protrusion 41a of the tank stopper 40 is the moment of the filter 30 Since it is not in contact with (33), it is unable to transmit rotational force to the moment part 33, and only the projection part 41a itself is rotated, so that the tank cap 40 is placed in the open position, but the filter 30 is still in the locked position. Will be maintained.

That is, as shown in (c) of FIG. 7, the stopper 41a of the tank stopper is in the open position and the stopper 32a of the tank stopper 40 can be opened, but the stopper 32a of the filter is still in the inlet ( Even if the pressure inside the tank is applied to the filter 30, the filter 30 is caught by the locking jaw 7a of the inlet 1 and is not separated out.

In this way, when the locking projection 32a of the filter 30 is caught and locked by the locking jaw 7a of the inlet 1, the user moves his hand out of the inlet 1 to remove the filter 30. What is necessary is just to hold up the moment part 33 provided in the upper part of the said filter 30 in (1).

According to the present invention as described above, even if the user puts the filter in the ion resin tank and does not lock the filter, once only the tank cap is locked, the filter is locked together with the tank cap so that the user does not need to lock the filter, which is very convenient for use. In addition, there is a unique effect that the conventional problem that the filter is eluted when opening the tank cap by forgetting to lock the filter is solved.
