Description NOBLEMETAL NANO COLLOID MAKER

Technical Field

[1] The present invention relates to a common-type noble metal nano colloid maker, which includes a consumable cartridge where noble metal wire is bonded; a cartridge holder part that enables attaching or detaching the cartridge and allows it to be connected to the high- voltage energy electrode part; a cartridge-moving part that moves the cartridge up and down; a disconnection- sensing part that detects whether the noble metal wire attached to the consumable cartridge electrode is disconnected; a high- voltage charging and discharging part that controls the charging and discharging of electric energy through a 2-step method relay switch and a surge killer designed to protect the circuit from the resulting surge and noise when underwater plasma oxurs; and a water cup weight-sensing part that detects whether the water cup contains a fixed amount of water, thereby allowing the simple production of noble metal nano colloids at home. Background Art

[2] In general, the liquid where matter is uniformly dispersed in molecular or ionic state is called a solvent. The state wherein corpuscles larger than regular molecules or ions and with diameter of about 1 nm to 100 nm are dispersed in gas or liquid without condensing or precipitating is called a colloid state. An entire body in colloid state is called a colloid.

[3] Recently, colloids started to be used widely as materials for various industrial and life applications. In particular, producing and applying the nano-sized colloid solvent of noble metals such as silver (Ag), gold (Au), or platinum (Pt) make up a method of improving health by increasing the absorbability of the corresponding component.

[4] Note, however, that the common techniques that are currently used to produce such noble metal nano colloid at home are the precipitating type electrolysis method and underwater plasma method due to resistive heat generation. First, silver (Ag) nano colloid-producing equipment using the predpitating-type electrolysis method are arranged into a simple shapes, e.g., two silver rods with positive and negative charges separated by a fixed distance and housed in a container or two facing plate-type silver electrodes that are separated and housed in a container. While silver nano colloid can be produced by depositing said electrodes in pure water such as distilled water and performing electrolysis, producing silver nano colloid takes 30 to 60 minutes using 250 to 500CC of water. Since distilled water must be used because materials with other components that are present in the water will react and produce impurities or precipitates, separate distilled water-producing equipment should be prepared, or distilled water must be purchased each time; thus reducing economic and operational efficiency.

[5] In addition, if such electrolysis method is applied to equipment to produce gold (Au) or platinum (Pt) nano colloids, the consumable electrode for each material will be very expensive. Moreover, if they are used for a fixed amount of time, part of the electrodes will be locally consumed and detached because of the characteristic of electrolysis. Such problems have prevented the commercialization of the technology.

[6] The underwater plasma method is a technique of producing nano colloid by applying charged high-density energy to wire metal inserted inside the solvent and inducing underwater plasma due to resistive heat generation during a short period (1 ~ 50μs). For nano colloid-producing equipment that has been developed to date using this method, the metal wire must be directly connected to each high- voltage electrode part where high-density energy is applied manually by the user. Since the strength of fixing the metal wire on the high- voltage electrode is not uniform, the characteristic of resistive heat generation will change as contact resistance changes. For the produced nano colloid, density reproducibility will deteriorate significantly. Worse, there were cases wherein nano colloids were not even produced because the contact characteristic was not good and high-density current leaked into the water.

[7] In addition, if a metal wire with diameter of 0.1 mm or less is used, problems such as difficulty in handling by the consumer, fragility, and difficulty in fixing to an electrode may oxur. If diameter of 0.1 to 0.15 mm is used, high-charging voltage will be required to trigger underwater plasma. As a result, the prices of the high- voltage part and other electronic parts will increase, and breakdowns, damage, and faulty operation of the charging and discharging circuits may oxur as a result of surge (surge: a high- impact pulse in an electric circuit that instantaneously increases the current or voltage) of several KA or greater and noise. Since loud noise is generated by the increasing metal vapor that oxurs during nano colloid production, it is not suitable for home use. This is why the technology has yet to be commercialized.

[8] In addition, for the cassette-type method wherein drilled film is coated with metal wire, more than 30% of the amount used were molded within the film when the film was coated with metal wire; thus rendering it unusable. When the metal wire fixed to the film was supplied to high- voltage electrodes, several problems arose. For one, only part of the high-density current was applied because of the large area of contact resistance for the metal wire that came into contact with the electrode. If the roll is loosened or unfastened due to pressure that occurred during nano colloid production, high-density current will leak into the water solvent because contact with the high- voltage electrode is hindered. As a result, nano colloid will not be produced. Disclosure of Invention Technical Problem

[9] Therefore, the present invention was conceived to solve the abovementioned problems. An underwater plasma method is applied to a common-type noble metal nano colloid maker to enable a user to produce nano colloids easily and safely by securing electric durability and safety for the high-voltage charging and discharging part during nano colloid production; in this way, the resulting surge or noise is absorbed and eliminated when underwater plasma oxurs, thereby maintaining the contact resistance between the metal wire and high- voltage electrodes uniformly to prevent the leakage of high-density current. Reproducibility is also secured, enabling the production of noble metal nano colloid with constant density. Finally, the cost of expendables and resulting noise are minimized. Technical Solution

[10] The present invention provides a common-type noble metal nano collide maker, which includes a consumable cartridge where noble metal wire is bonded; a cartridge holder part that enables attaching and detaching the cartridge and allows it to be connected to the high- voltage energy electrode part; a cartridge-moving part that moves the cartridge up and down; a disconnection- sensing part that detects whether the noble metal wire attached to the consumable cartridge electrode is disconnected; a high- voltage charging and discharging part that controls the charging and discharging of electric energy through a 2-step method relay switch and a surge killer designed to protect the circuit from the resulting surge and noise when underwater plasma oxurs; and a water cup weight-sensing part that detects whether the water cup contains a fixed amount of water, thereby enabling the simple production of noble metal nano colloids even at home.

[11] This common-type noble metal nano colloid maker can be simply described as follows. A waterspout is mounted on the lower part to support the water cup; for the upper part, a noble metal wire measuring 50/M or less is connected to the cartridge- moving part so that the cartridge holder part that attaches and detaches the bonded consumable cartridge can move to the upper part of the waterspout. If the cartridge moves inside the water cup after the water cup filled with a fixed amount of water is positioned on the upper part of the waterspout, charged high-density energy would be impressed to the noble metal wire inside the consumable cartridge. Metal vapor is created for a short period (1 to 50μs) due to the underwater plasma, since charged high-density energy is applied to the noble metal wire inside the consumable cartridge. At the same time, a critical pressure is exceeded due to the law of inertia and the pinch effect, and an explosion oxur; thus dispersing it widely in the solvent and causing it to cool rapidly and produce the noble metal nano colloid.

[12] The consumable cartridge includes an upper part and a lower part as well as positive and negative electrodes with symmetrical structure. First, the cartridge is mounted by bonding the metal wire to the positive and negative electrodes inserted into the lower part of the cartridge.

[13] The lower part of the waterspout is equipped with a pressure sensor that detects the weight, thereby enabling detecting whether the water cup is filled with a fixed amount of water. A water cup weight-sensing part that only operates if there is enough water to submerge the cartridge in water completely is also mounted for improved safety. Brief Description of the Drawings

Best Mode for Carrying Out the Invention

[39] A common-type noble metal nano colloid maker of the present invention enables the safe and simple production of noble metal nano colloids even at home. It shall be described in detail with reference to the accompanying drawings.

[40] As shown in Figure 1 and Figure 3, the noble metal nano colloid maker 1 includes a cartridge 10 where noble metal wire has been bonded; a cartridge holder part 20 that allows the cartridge 10 to be attached to and detached from the upper part and the high- voltage energy electrode part to be connected; a cartridge-moving part 30 that moves the cartridge holder part 20 up and down from the side; and a water cup weight- sensing part 40 having a waterspout 41 that places the water cup 80 on the lower part and a pressure sensor 42 that detects the weight of the water cup 80 placed inside an " τ= "-shaped case 70.

[41] Specifically, the cartridge 10 includes an upper part 11, a lower part 12 and a pair of

"E" -shaped electrodes 13 with symmetrical structure as shown in Figures 6 and 7. The production process of the cartridge 10 is as follows. After one pair of electrodes 13 are fixed so that they face each other on the side of the lower part 12 of the cartridge equipped with a grooved, round-shaped handle 15 on the front as well as multiple projections 14 on the side, metal wire is bonded to each of the centrally protruding part of the "E"-shaped electrode 13. The upper part of the cartridge 11 having the same shape is attached to the lower part 12 of the cartridge using the hook method or ultrasonic bonding method. [42] Mounting each handle 15 in front as described above makes the invention easy to use. Likewise, the many projections 14 on the side prevent the cartridge 10 inserted in the cartridge holder part 20 from moving or getting detached.

[43] By drilling many holes in the surface of the upper part 11 and the lower part 12 of the cartridge, the nano colloid is dispersed well in the water due to the resulting pressure when underwater plasma is created.

[44] At this point, the bonded metal wire should have a diameter of 10 to 50 μm and a length of 20 to 60 mm. Silver (Ag) or brass coated with gold (Au) or platinum (Pt) should be used as the material for the electrodes 13. To make sure the present invention is harmless to the human body, poljcarbonate material — which is nontoxic at room temperature — is used for the upper part 11 and the lower part 12 of the cartridge.

[45] By using a ball-bonder or a wedge-bonder that make up the semiconductor process equipment during the bonding of the noble metal wire, metal wire can be handled rapidly and easily. By controlling the temperature, pressure, and ultrasound when bonding the metal wire with the electrodes 13, two contact planes are combined by enabling movement between metals. This will prevent metal wire loss, since the contact resistance is uniform; thus preventing in advance the penetration of foreign substance and impurities and having the entire bonded metal wire converted into nano colloid due to the underwater plasma.

[46] The part that protrudes on both sides of the "E"-shaped electrode 13 secures reproducibility so that noble metal nano colloid with constant density is always produced by maintaining identical contact resistance. This is done by having a contact-type structure wherein each comes into contact simultaneously with the electrodes in the high- voltage part when the cartridge 10 is mounted on the cartridge holder part 20.

[47] As a preferred embodiment of the present invention, the contact area between the cartridge electrode and the metal wire is widened while bonding noble metal wire. To maximize energy efficiency, noble metal wire with diameter of 10 to 50 μm and length of 40 mm can be bonded to the negative and positive electrodes 13 of the cartridge 10 at intervals of at least 10 mm by dividing the task into 4.

[48] As illustrated in Figure 2 or Figure 3, the cartridge holder part 20 is fixed by inserting the cartridge 10; a high-voltage electrode part (not illustrated) is mounted so that high-voltage electrode that applies high-density current comes into contact with each electrode 13 for the inserted cartridge 10. The cartridge holder part 20 is mounted so that movement in the up and down direction is possible through the cartridge- moving part 30 mounted as one body in the upper part.

[49] The outside of the case 70 is additionally equipped with an exchange switch 21 that moves the cartridge holder part 20 to the lower part, separates and exchanges the cartridge 10 fixed inside, and moves the cartridge holder part 20 to the upper part again as illustrated in Figure 4.

[50] The moving part 30 of the cartridge is mounted so that it can move the cartridge holder part 20 up and down while simultaneously supporting a soundproofing function to minimize the resulting noise when a nano colloid is created as illustrated in Figure 2 or Figure 3. The motor 31 mounted on the upper part is connected to a deceleration gear 32. Since the deceleration gear 32 rotates due to the control of the motor 31, the connected worm gear 33 rotates at the same time. As a moving guide 34 connected to the worm gear 33 follows the worm gear 33 by moving up or down, the cartridge holder part 20 connected as a single body to the lower part of the moving guide 34 moves in unison.

[51] Another factor that makes the present invention even more appropriate for use at home is the minimized noise during operation. To minimize the driving noise due to the deceleration gear 32, the composition can be changed so that the worm gear 33 is operated using a V belt (not illustrated) instead of the deceleration gear 32.

[52] At this point, to prevent the eccentricity or drooping of the cartridge holder part 20, multiple guide holes can be formed in the side of a support 37 where the moving guide 34 moves. Mounting a linear bushing (not illustrated) that is symmetrical with the worm gear 33 is also recommended.

[53] In addition, the resulting noise when nano colloid is created can be minimized by having the moving guide 34 move with the worm gear 33 as the main axis and pressing the cup cover 35 that has been mounted so that it can move up and down along the side of the cartridge holder part 20 as shown in Figure 3. Noise can be prevented by the packing 36 mounted along the lower part of the cup cover 35 covering the upper part of the water cup 80 as the cup cover 35 moves toward the lower part.

[54] In particular, if the cartridge holder part 20 and the cup cover 35 exhibit identical up and down movement, the cartridge holder part 20 will always be positioned on the internal side of the cup cover 35. Since the cartridge 10 cannot be attached or detached, it should be mounted so that the cup cover 35 is pressed and it moves toward the lower part after the cartridge holder part 20 has traveled a fixed distance or more toward the lower part.

[55] To check the distance traveled by the cartridge holder part 20 as well as whether it stopped, an upper sensor 38 and a lower sensor 39 are mounted on the upper and lower parts of the moving guide 34, respectively, as shown in Figure 5 so that the moving guide 34 — which has traveled a fixed distance to the upper or lower part — stops.

[56] As shown in Figure 2 or Figure 3, the water cup weight-sensing part 40 includes the waterspout 41 whose upper part is equipped with a water cup 80 and the pressure sensor 42 that detects whether the water cup 80 is filled with a fixed amount of water. If noble metal nano colloid is produced, the water cup must be filled with water up to a level greater than the height at which the cartridge 10 moves toward the lower part. This is because the nano colloid is produced safely only if high-density current is applied through the high-voltage electrode part with the cartridge 10 equipped with noble metal wire always submerged in water and if underwater plasma occurs.

[57] If the amount of water is insufficient, or if there is no water and high-density current is applied to the cartridge 10, problems such as plasma occurring in air and disappearing as nano vapor and occurrence of loud noise could arise. To prevent this, the noble metal nano colloid maker 1 has been developed so that it is operated exclusively by the pressure sensor 42 only if a certain weight is reached.

[58] Finally, a disconnection-sensing part 50 and a high-voltage charging and discharging part 60 are mounted inside the case 70 as illustrated in Figure 8. The disconnection- sensing part 50 includes a disconnection-sensing switch, a MPU with built-in microprocessor, a power supply for disconnection sensing, and a surge killer for circuit protection. It detects whether the noble metal wire attached to the electrodes 13 inside the cartridge 10 is disconnected. The high-voltage charging and discharging part 60 has a charge switch equipped with surge killer, a condenser, a discharge switch, a high- voltage electrode part, and an AC input to protect the circuit from the resulting surge and noise when underwater plasma oxurs and controls the charging and discharging of electric energy.

[59] The control method is described as follows. During the operation of the cartridge holder part 20 where the cartridge 10 is mounted, the MPU with a built-in microprocessor detects whether the metal wire bonded to the electrode inside the cartridge 10 is disconnected using the power supply for disconnection sensing. If the metal wire is disconnected, a request to exchange the cartridge 10 is sent using voice or lights through the built-in speaker or LED in MPU. Otherwise, the voltage raised to a certain degree by rectifying it through the AC input power supply charges the condenser when the charge switch is turned ON. When a signal indicating that the cartridge 10 has been submerged completely by the cartridge-moving part 30 is received through the lower sensor 39, the charge switch is turned OFF, the discharge switch is turned ON, and a nano colloid is produced when high-density current is applied to the electrodes 13 through the high- voltage electrode in the cartridge holder part 20.

[60] In other words, to protect the circuit from the resulting surge and noise when nano colloid is created, each of the disconnection detection switch, the charge switch, and the discharge switch is turned on and turned off in order while arranging each surge Mller on the exterior of the switch in parallel.

[61] If a circular- type cartridge is mounted by inserting a positive electrode that makes the cartridge 10 available for common use at the circular center part and inserting many negative electrodes at regular intervals on the circular outside part, noble metal nano colloid may be produced repeatedly in the same number as that of the bonded metal wires. At this point, the circuit must be mounted so that the number of disconnection detection switches and surge killers in the cartridge disconnection-sensing part is increased by the same number as that in the number of metal wires. In addition, if the circuit is mounted so that the number of negative electrodes in the discharge switch and high- voltage electrode part increases by the same number, nano colloid can be produced continuously in the same number as that of the mounted noble metal wires; high-density nano colloid can also be produced by triggering the explosion of noble metal wires simultaneously and underwater for a multiple number of times.

[62] The circuit and program are arranged so that the charge switch is turned off after the production of nano colloid is completed after being turned on for the first time. Thus, only one will suffice when nano colloid is produced continuously.

[63] The noble metal nano colloid maker 1 has a control part 51 mounted on one side, allowing the production of nano colloid due to the up and down movement and application of high-density current of the cartridge 10 to be controlled and displaying whether the cartridge 10 is exchanged and whether there is a fixed amount of water inside the water cup 80 at the same time.

[64] Finally, the noise that occurs during nano colloid production is minimized by mounting a water cup 83 whose circumference is equal to that of the cup cover 35 and completely sealing the upper part of the water cup 80 through a paddng 36. Through a volume display part 81 indicating the fixed height of the water cup 80, the user will know the appropriate amount of water that will fill the water cup 80.

[65] The operation method for this common-type noble metal nano colloid maker 1 is described as follows.

[66] First, if the water cup 80 is taken outside from the water cup weight-sensing part 40 for the case 70, and the exchange switch 21 is pressed, the deceleration gear 32 and the worm gear 33 will move consecutively due to the motor 31 in the cartridge-moving part 30. After moving toward the lower part for a fixed distance, the moving guide 34 and the cartridge holder part 20 will stop after being detected by the lower sensor 39.

[67] Therefore, if the exchange switch 21 is pressed again after inserting and fixing the cartridge 10 inside the cartridge holder part 20, the motor 31 for the cartridge-moving part 30 will operate in the opposite direction. The deceleration gear 32 and the worm gear 33 will also move consecutively again. After moving toward the upper part for a fixed distance, the moving guide 34 and the cartridge holder part 20 will stop after being detected by the upper sensor 39.

[68] Afterward, if the water cup 80 is positioned on the upper part of the waterspout 41 after the water cup 80 is filled with water up to the volume display part 81, whether the water amount inside the water cup 80 as detected by the pressure sensor 42 reaches a certain amount is displayed on the control part 51. This completes the operation preparation.

[69] After such preparation is completed, and if the control part 65 is activated for nano colloid production, the disconnection-sensing part 50 will detect whether the cartridge 10 is disconnected. If there is no problem, the charge switch will turn ON immediately. The voltage raised to a certain level by rectifying it through the AC input power supply will charge the condenser. At the same time, the cartridge 10 fixed to the cartridge holder part 20 by the cartridge-moving part 30 will move toward the lower part. If a signal indicating that movement over a certain distance has been completed is received through the lower sensor 39, the cartridge-moving part 30 will stop, the charge switch will be turned off, and the discharge switch will be turned on right away; thus causing the noble metal wire inside the cartridge 10 to produce nano colloid by passing the underwater plasma state due to the high-density current through the high- voltage part electrode in the cartridge holder part 20.

[70] At this point, if the cartridge holder part 20 moves toward the lower part, the resulting noise when underwater plasma oxurs will be eliminated completely by the cup cover 35 that moves toward the lower part simultaneously; thus causing the paddng 36 to attach completely and press the upper part of the water cup 83.

[71] After the series of operations are completed, the cartridge-moving part 30 will move toward the upper part again. If a signal indicating that a certain distance has been traveled is received through the upper sensor 38, the user will be notified that nano colloid production has been completed through the speaker or indicator lamp.

[72] According to the embodiment of the present invention, the metal wire mounted on the cartridge 10 should have a diameter of 10 to 50/M and a length of 20 to 60 mm. Although there is a difference in the type of noble metal, e.g., platinum (Pt), gold (Au), and silver (Ag), setting the voltage to 1,000 to 1,300V and condenser charging capadt y to 10 to 100//F is recommended.

[73] By developing the noble metal nano colloid maker 1 using the method described above, rapid and stable production of small noble metal nano colloids is enabled. Since noble metal nano colloids can be produced several times based on the simple method of exchanging the cartridge 10, it can be used easily even in homes.

[74] Though the present invention has been described in detail using the embodiments and drawings, the present invention is not limited thereto. Various changes and modifications can be made within the spirit and scope of the invention, defined in the appended claims, by those having ordinary skill in the art. Industrial Applicability

[75] As described above, the present invention absorbs and eliminates the resulting surge or noise when underwater plasma oxurs, blocks the leakage of high-density current while securing reproducibility so that noble metal nano colloid of constant density can be produced, reduces the cost of expendables by using bonded noble metal wire, minimizes the resulting noise when underwater plasma oxurs through a cup cover that seals the upper part of the water cup, and ensures the convenience and safety of the user at the same time by securing electric durability and safety through the disconnection-sensing part and high- voltage charging and discharging part when producing nano colloids based on an underwater plasma method.
