In addition, the purified water is preferably formed so that the molecular structure is a hexagonal copper structure.

It is preferable that the purified water is magnetized by the magnetic field of the magnet while passing between the two magnets so that the molecular structure is formed in a hexagonal ring structure.

A process for converting purified water into hexagonal water and adding and mixing additives to prepare the lens cleaning solution and the manufacturing apparatus 10 used for this will be described as follows.

First, as shown in FIG. 1, a purified water manufacturing step of forming purified water into a hexagonal ring structure of water molecules, a step of adding an additive containing sodium chloride, sorbic acid, and sodium hyaluronate to the purified water, and mixing the purified water and the additive A lens cleaning solution is prepared through the following steps.

Purified water is subjected to a process of freezing purified water, thawing it again, and magnetizing the purified water as shown in FIG. 2 in order to make the water molecules have a hexagonal ring structure.

One of the conditions that facilitates the formation of hexagonal water is low temperature, and when water turns into ice, many water molecules are converted into hexagonal rings. It induces a hexagonal ring structure.

And by magnetizing the thawed water, the remaining water molecules that are not converted into a hexagonal ring structure are induced to become a hexagonal ring structure as much as possible.

An embodiment of the manufacturing apparatus 10 for manufacturing a lens cleaning solution through these steps is shown in FIGS. 3 to 5 .

Referring to the drawings, the manufacturing apparatus 10 includes a defrosting machine 100 , a discharge flow path 200 connected to the defrost machine 100 , a magnetization flow path 300 connected to the discharge flow path 200 , a magnetization flow path ( A plurality of magnets installed in 300) and a supply nozzle 400, a cooling unit for maintaining the temperature of the discharge path 200 and the magnetization path 300 low, and a storage unit 500 for storing purified water and additives; It is installed in the storage unit 500 and includes a stirring unit 600 for stirring so that purified water and additives are mixed.

The defroster 100 is a space for defrosting purified water in an ice state, and after putting ice grains of a predetermined size into the defrosting machine 100, they are melted through natural thawing. When purified water is melted, purified water is discharged from the defrosting machine 100 through the discharge flow path 200, and a purified water flow rate sensor for measuring the discharge amount of purified water discharged on the discharge port or discharge flow path 200 of the defrosting machine 100 ( 210) is provided.

The discharge flow path 200 is connected to the magnetization flow path 300, and the magnetization flow path 300 applies a strong magnetic field to the purified water passing through the magnetization flow path 300 by a magnet to magnetize the purified water, thereby forming a hexagonal ring-shaped molecular structure. to induce them to have

The magnetization flow path 300 includes a plurality of parallel pipes 310 extending in parallel with each other and connecting pipes 320 connecting one side and the other side of the parallel pipes 310 to each other to form a single flow path.

The parallel tubes 310 are connected by the connecting tubes 320 to form a flow path connected in a zigzag manner as shown in FIG. 3 . A magnetization electromagnet 330 for applying a magnetic field for magnetization is installed between the parallel tubes 310 .

The magnetization electromagnet 330 must form a magnetic field sufficient to magnetize purified water to become a magnetized hexagonal water. In the present invention, an electromagnet is applied to form a magnetic field by applying electricity, but unlike this, it is sufficient to generate a magnetized hexagonal water. A permanent magnet capable of forming a magnetic field may be applied.

In addition, a first cooling unit 340 is formed in the discharge passage 200 and the magnetization passage 300 to maintain the temperature of purified water passing through the passage.

As described above, the lower the temperature of water, the easier the molecular structure is to be maintained in a hexagonal ring shape. Once the molecular structure has changed, the molecular structure does not change easily even if the conditions change, but the molecular structure of a hexagonal ring may be broken as the structure of some water molecules is transformed into a molecular structure of another shape such as a pentagonal ring shape due to an increase in temperature. . Therefore, it is preferable to maintain the temperature of the purified water passing through the discharge flow path 200 and the magnetization flow path 300 at a temperature of 2° C. to 6° C. so that the molecular structure can be easily maintained. To this end, temperature sensors 350 are provided for each section on the discharge flow path 200 and the magnetization flow path 300 , and temperature information of these temperature sensors 350 is transmitted to the control unit 700 , so that the control unit 700 Controls the driving of the first cooling unit 340 . That is, the first cooling unit 340 is operated or stopped so that the temperature of the purified water is maintained within a set temperature range.

In addition, supply nozzles 400 for adding additives are installed in the connection pipe 320 . If the first supply nozzle 410, the second supply nozzle 420, and the third supply nozzle 430 are sequentially referred to as the first supply nozzle 410, the second supply nozzle 420, and the third supply nozzle 430 along the moving direction of the purified water, sodium chloride is supplied from the first supply nozzle 410, Sorbic acid is supplied from the second supply nozzle 420 , and sodium hyaluronate is supplied from the third supply nozzle 430 .

The first supply nozzle 410, the second supply nozzle 420, and the third supply nozzle 430 control the input amount of each additive according to the supply amount of purified water measured by the flow sensor. That is, when the purified water is 100 parts by weight, the sodium chloride is 0.8 to 0.9 parts by weight, the sorbic acid is 0.08 to 0.1 parts by weight, and the sodium hyaluronate is 0.0001 to 0.0003 parts by weight. The supply amount is controlled to be added to the purified water.

Since the additive contained in purified water flows and flows in a zigzag state along the connection passage between the parallel pipe 310 and the connecting pipe 320, the purified water and the additive are primarily mixed and supplied to the storage unit 500 to be described later. .

As shown in FIG. 4 , the storage unit 500 is filled with a mixture of purified water and additives, that is, a lens cleaning solution. A second cooling unit 510 in the form of a heat exchanger through which a refrigerant flows so that the lens cleaning solution maintains a low temperature state is formed in the storage unit 500 . The second cooling unit 510 may be a tube through which the same refrigerant as the cooling unit flows.

The storage unit 500 is further provided with a stirring unit 600 for mixing purified water and additives.

The stirring unit 600 is in the shape of a rod installed inside the storage unit 500, and a rotating body 610 having N-pole or S-pole fixed electrodes at both ends, and the rotating body 610. It includes a movable electrode 620 installed in the storage unit 500 for rotational driving.

The movable electrode 620 is provided on the outside of the side of the storage unit 500 and is an electromagnet whose polarity is continuously changed under the control of the control unit 700 .

The rotating body 610 has a bar shape that is not connected to a separate rotating shaft as described above, and fixed electrodes are formed at both ends, so that the movable electrode 620 rotates while a repulsive or attractive force is applied.

The control unit 700 applies electricity so that the polarity of the movable electrode 620 is changed, and the rotating body 610 is rotated by the electrode of the movable electrode 620 , and purified water and additives introduced into the storage unit 500 . mix to create a lens cleaning solution.

Since the stirring unit 600 of the present invention does not have a structure in which a separate rotating shaft and a motor for rotating the rotating shaft are installed for mixing purified water and additives, the temperature of purified water is prevented from rising due to frictional heat generated during the rotation of the rotating shaft In addition, it is possible to fundamentally block the inflow of foreign substances through the penetrating portion through which the rotating shaft passes, making it possible to manufacture a hygienic lens cleaning solution.

The lens cleaning solution according to the present invention described above is formed by mixing sodium chloride, sorbic acid, and sodium hyaluronate in purified water having a hexagonal ring-shaped molecular structure, thereby further increasing cleaning ability and human affinity, thereby increasing the eye of the wearer who wears the lens. It is more beneficial to protect health.

In addition, when the lens cleaning solution is prepared according to the method proposed in the present invention, purified water having a hexagonal ring-shaped molecular structure can be easily formed to prepare the lens cleaning solution. The hexagonal ring-shaped water molecule structure can be easily maintained.

The description of the presented embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the scope of the invention. Thus, the present invention is not to be limited to the embodiments presented herein but should be construed in the widest scope consistent with the principles and novel features presented herein.
