Description

Instrument for providing microcurrent and vibration

The present invention relates to a microcurrent and vibration providing mechanism, and more preferably to a microcurrent and vibration providing mechanism for supplying microcurrent and vibrating a vibrating element while worn in close contact with the skin.

The massager or vibration stimulator is classified into a full body massage device for massaging the whole body and a local massage device for massaging a part of the body according to the massage area. The local massage device is manufactured to be suitable for various and local body parts. For example, the local massage device for a body part having a shape that can be worn with a belt, such as the waist, neck, limbs, etc., is mainly manufactured in a belt type. do.

On the other hand, in the case of the face, a local massage must be used, and unlike the massager described above, it is necessary to stimulate sensitive skin tissue, so it should be operated as light and smooth as possible due to its characteristics. In particular, in the case of the face, it is not possible to wear a belt, and massage parts such as the temple, chin, nose and cheekbones are scattered in various ways, so it is not suitable for the use of a belt or rod type massage device. As a result, side effects of the facial skeleton and skin side effects occur.

In order to solve this problem, roughly two types of facial massage devices have been proposed. One of these methods is a technology (Patent Document 1) in which a mask shape is manufactured from an injection material of a hard material resembling the shape of a face, a vibration motor is installed inside the mask shape, and the vibration of the vibration motor is transmitted to the face through a pressing protrusion (Patent Document 1). However, in this method, the facial contour shape differs from person to person, so masks of various sizes and shapes must be prepared. there was ham In addition, a vibrating element must be installed at a plurality of positions of a mask made of an injection material made of a hard material resembling the shape of a face and electrically connected thereto, but most of them have to be done manually, so there is a problem in that the manufacturing cost increases.

Another method is to form a two-dimensional flat mask as disclosed in Patent Document 2 below, fix it to the face contour using a fastener such as Velcro, and apply vibration. This method has an advantage in that it is easier to arrange a circuit element including a vibrating element than the first method, but it has a problem in that it is difficult to manufacture to adhere to various face sizes and shapes. In particular, in order to be worn appropriately for various face sizes and shapes, a two-dimensional mask shape should be formed of a resilient material and configured to be stretched when worn, but there was a problem in that a circuit element was disconnected when worn.

The inventor of the present invention has been developing a vibration providing device including a mask that provides a vibration function to the skin since early 2018. The vibration providing device is provided with a plurality of vibrating elements, and while stably connecting wires for supplying power to each vibrating element and configured to be closely coupled to the skin, it has been difficult to manufacture suitable for mass production. In order to solve this manufacturing problem, the inventor of the present application has applied for a patent as presented in Patent Document 3 and has been registered. The technology presented in Patent Document 3 relates to a manufacturing technology for facilitating production by forming a coupling groove in a power line for supplying power to a vibrating device and inserting conductive silicon into the coupling groove. However, as a result of the inventor of the present application trying to produce according to Patent Document 3, it was found that manual labor is required to install the vibrating element, so the production cost is increased and thus it is difficult to apply the technology.

Patent Document 1: Korean Patent Publication No. 10-2009-0121643 (published on November 26, 2009) Patent Document 2: Korean Patent Application Laid-Open No. 10-1998-087763 (published on Aug. 2, 1998) Patent Document 3: Korean Patent No. 10-1967679 (Registered on April 4, 2019)

An object of the present invention is to provide a micro-current and vibration providing mechanism that can be manufactured simply and at low cost without manual work.

The above object of the present invention is a sealing cap having an accommodating space therein, having a tetrahedral shape from which the bottom is removed, and mounted in a soldering manner with the first top-surface pattern electrode on the top surface along the edge of the tetrahedral bottom surface; A vibrating element mounted to be electrically connected to the third lower surface pattern electrode and the fourth lower surface pattern electrode, the first elastic contact electrode mounted in a soldering manner with the first lower surface pattern electrode on the lower surface, and the second lower surface pattern electrode on the lower surface; A flexible PCB having a second elastic contact electrode mounted by a soldering method, and at least a portion of the first elastic contact electrode and the second elastic contact electrode are exposed to the outside of the elastic molded body. It can be achieved by a microcurrent and vibration providing mechanism that includes.

The sealing cap may further increase the closeness by being soldered to the first upper surface pattern electrode and the second upper surface pattern electrode respectively on the upper surface of the flexible PCB along the inner periphery bottom edge and the outer periphery bottom edge.

In addition, the vibrating element is soldered to the third upper surface pattern electrode and the fourth upper surface pattern electrode on the upper surface of the flexible PCB, and the third upper surface pattern electrode is floated with the third lower surface pattern electrode and the fourth upper surface pattern electrode and the fourth lower surface pattern electrode, respectively. It is preferable to connect to the conductive material through a through hole.

It is preferable that the flexible PCB be further mounted with a control unit that independently applies power for on/off operation to each vibrating element, and a microcurrent generator that alternately supplies a minute current to the first and second elastic contact electrodes.

The inventor of the present application proposes a method of mounting the vibrating element unit on a flexible substrate by soldering in order to overcome the difficulties in manufacturing the mask according to Patent Document 3, and patent registration No. 10-2025131 (September 2019) .19. Registration, hereinafter referred to as 'first developed technology').

In Patent Registration No. 10-2025131, the vibrating element part mounted on a flexible substrate was marketed under the name of 'coin-type vibrating element'. 1 is an exterior photograph related to a coin-type vibrating element sold in the market, and FIG. 2 is an exploded photograph. The coin-type vibrating element 30 has an appearance as shown in FIG. As shown in FIG. 2 , the coin-type vibration element has a FPCB 32 for the vibration element placed in a lower case 31 having a fitting rod 33 formed in the center, and a magnetic steel 34 is installed thereon. The eccentric rotor 35 shown in FIG. 2 (b) is placed on the magnetic steel 34, and finally, when the upper case 36 shown in FIG. 2 (c) is turned over and combined, as shown in FIG. 1 (b) The manufacture of the sealed coin-type vibration element to the naked eye is completed.

After soldering a plurality of coin-type vibrating elements on a flexible substrate as shown in FIG. 3, the present inventor puts the flexible substrate to which the vibrating element part is soldered into a mold at high temperature and high pressure on the outer surface of an elastic body (e.g., silicon ) was used as a mask by injection molding. However, several tons of pressure is applied during the silicone molding process. Silicon penetrates into the microscopic gap where the combination of the upper case and the lower case of the coin-type vibrating element is not completely sealed, resulting in manufacturing defects in which the rotor does not operate. It was impossible to mass-produce the product.

Since then, the inventor of the present application has produced and sold a mask in which only the contact electrode is formed on the flexible substrate, the contact electrode is exposed to the outside, and the remaining flexible substrate is formed to be depressed inside the silicon molded body. 10-2019-0108622 (applied on September 3, 2019, hereinafter referred to as 'second development technology').

The second development technology has the advantage of not having to throw away the mask itself since only the broken vibrating element part needs to be replaced with a new one if some vibrating element parts are broken. Nevertheless, the second development technology could not solve the problem of increasing manufacturing cost because the vibrating element part had to be separately manufactured and a separate case for only the vibrating element part had to be used.

In addition, in the first development technology and the second development technology, an electric signal is supplied to the vibration element part, the LED and the first elastic contact electrode, and the control element part having a communication module that communicates with the outside is inserted and installed later like the vibration element part has been proposed. In order to insert the control element unit later in this way, a third printed circuit board (not shown in FIG. 3 ) provided in the control element unit formed by a separate process and a second printed circuit board (FIG. After the reference symbol 40 of 3 is manufactured, a process of soldering with the flexible substrate (reference symbol 50 of FIG. 3 ) is required. Therefore, in manufacturing a mask by applying the first and second development technologies, the vibration element part and the control element part have to be separately manufactured, and many processes such as combining a plurality of printed circuit boards are required, so the manufacturing cost is increased. There was a problem that it was difficult to popularize.

Accordingly, the inventor of the present application mounts all circuit elements constituting the vibration element, the elastic contact electrode and the control element part on one flexible printed circuit board in a factory using the SMT (Surface Mounting Technology) method, and it can be molded with silicon at high temperature and high pressure. An object of the present invention is to provide a microcurrent and vibration providing mechanism. Most of the description is described as being implemented in a mask shape according to the shape of the face, but the microcurrent and vibration providing mechanism according to the present invention can be manufactured in various shapes that are comfortable to wear on the neck, wrist, shoulder, etc., of course.

In order to implement this technology, the vibrating element must be mounted on a flexible PCB in a completely sealed state. 4 is an example of a vibrating device mounted in the present invention, FIG. 5 is a cross-sectional view of a configuration in which the vibrating device is mounted in a completely sealed state on a flexible PCB as an embodiment of the present invention, and FIG. 6 is the flexible of FIG. This is a plan view of the PCB.

It is possible. In the case of using a coin-type vibrating element, for example, the upper and lower cases may be removed and only the FPCB, magnetic steel, and eccentric rotor, which are the minimum components for realizing the vibrating element, may be configured.

As shown in FIG. 5, the vibration element and the sealing cap are soldered to the upper surface of the flexible PCB. The flexible PCB can use a double-sided board, and the double-sided flexible PCB is provided with upper surface pattern electrodes 51b1, 51b2, 51b3, 51b4 on an upper portion of the flexible substrate 51a1, and a flexible substrate upper cover layer 51a2 is provided on the upper portion of the flexible substrate. , the lower surface pattern electrodes (51c1, 51c2, 51c3, 51c4) are provided under the flexible substrate lower cover layer (51a3) is provided under the.

The layer 51a3 is soldered using solder and the upper surface pattern electrode exposed to the removed region. The flexible substrate 51a, the flexible substrate upper cover layer 51a2, and the flexible substrate lower cover layer 51a3 are usually made of polyamide. 6 shows the upper surface pattern electrodes 51b1 and 51b2 formed on the upper surface of the flexible PCB to be soldered with the sealing cap on the left side, and the upper surface pattern electrodes 51b1 and 51b2 and the lower edge surface of the sealing cap which are soldered to the right side are shown on the right side. .

As shown in FIGS. 5(a) and 6(a), the vibrating element 30 is mounted on the upper surface of the flexible PCB, and the entire circumference of the vibrating element is along the open bottom edge of the sealing cap 70. The first upper electrode pattern Solder with (51b1). The sealing cap 70 was formed to withstand high temperature and high pressure during silicone injection molding by removing the base and forming a hollow hexahedral or cylindrical shape. The lower edge of the sealing cap 70 was formed so as to be leveled on one plane so as to be completely sealed by soldering with the first upper electrode pattern 51b1. As shown in FIGS. 5(b) and 6(b), the lower edge surface of the sealing cap 70 has an inner peripheral edge and an outer peripheral edge with a first upper electrode pattern 51b1 and a second upper electrode pattern 51b2, respectively. It can also be sealed by soldering. As shown on the right side of each of FIGS. 6(a) and 6(b), the lower edge surface of the sealing cap 70 may be formed in a flat shape or may be formed in a suitable shape to have a concave shape upward.

5 and 6, the + and - electrodes of the vibrating element are soldered to the third upper pattern electrode 51b3 and the fourth upper pattern electrode 51b4. The third upper pattern electrode 51b3 and the fourth upper pattern electrode 51b4 are respectively connected to the third lower pattern electrode 51c3 and the fourth lower pattern electrode 51c4 through a through hole.

As shown in FIG. 5 , the first elastic contact electrode 55 is soldered to the first lower pattern electrode 51c1 , and the second elastic contact electrode 55 is soldered to the second lower pattern electrode 51c2 . At least some lower surfaces of the first elastic contact electrode 55 and the second elastic contact electrode 57 are formed to be exposed so as to be in contact with the skin.

7 is an example of the upper surface of the flexible PCB for a mask manufactured according to the present invention, and FIG. 8 is an example of the rear surface. 7 and 8, the flexible PCB 50 is manufactured according to the shape of the face, and a plurality of sealing caps 70a to 70h are mounted by soldering at a position where vibration is to be applied, and the vibrating element is a sealing cap. (70a ~ 70h) It is mounted inside. The actual vibration elements 30a to 30h are not visible in the rear direction of the flexible PCB 50 of FIG. As shown in FIG. 8 , a first elastic contact electrode 55 and a second elastic contact electrode 57 are provided on the rear surface of the flexible PCB 50 in contact with the skin to apply a microcurrent. With reference to FIG. 8 , only the two on the right are the second elastic contact electrodes 57 , and the rest are configured as the first elastic contact electrodes 55 . In addition to the vibration element and the sealing cap, wiring and circuit elements for supplying electrical control signals and power signals are installed on the flexible PCB 50, but are not separately indicated. A connection terminal unit 13 (eg, 'USB terminal unit') for connecting to an external device (eg, a battery, etc.) may be installed at one end of the flexible PCB 50 .

9 is an embodiment of a circuit configuration of a control element unit according to the present invention. The control element unit 10 is installed on the flexible PCB 50 as described above. It consists of a control unit 110 having an antenna 117 and a wireless communication module 115 , an operation mode switch 11 , a connection terminal unit 13 , a power control module 120 , and a microcurrent generator 140 . Although the term micro-current generator 140 is used in the present invention, the micro-current generator 140 may be implemented as one programmable control chip (CPU). The control element unit 110 shown in FIG. 9 is implemented to be controlled through an external device (200, for example, a smartphone equipped with a dedicated control app) connected through wireless communication. Of course, the smart phone can be connected by wire through the connection terminal unit 13 . A simple control was implemented so that the control element unit 110 could be controlled even through the operation mode switch 11 . The mask of the present invention is designed in a form that does not include a battery. Since there is a risk of explosion when the battery is subjected to high temperature and high pressure, the operating power is configured to be supplied from the battery connected through the connection terminal unit 13 in order to avoid this problem.

The microcurrent refers to a small-sized current supplied to the body while changing the polarity through two electrodes (the first elastic contact electrode and the second elastic contact electrode) that are spaced apart from each other and contact the body. Accordingly, various microcurrent patterns can be formed by using the size of the supplied microcurrent, the interval at which the microcurrent is applied, and the change in the size of the supplied microcurrent per time. The micro-current generator 140 is provided by pre-stored a plurality of micro-current patterns for generating micro-currents. When an operation signal or control data for selecting a plurality of microcurrent patterns is input from an external device (200, a smart phone equipped with a dedicated control app, etc.), one of the stored plurality of microcurrent patterns is selected and the first elastic contact electrode and the second 2 It is supplied to the elastic contact electrode. Of course, when receiving control data from an external device via wired or wireless, the microcurrent generator 140 controls the first elastic contact electrode and the second elastic contact electrode from an external device instead of selecting and using a pre-stored microcurrent pattern. Of course, it is possible to provide a microcurrent to each of the first and second elastic contact electrodes after receiving the control data and analyzing it.

The vibrating device may be implemented as a piezo, a voice coil motor (VCM), and a vibrating motor having an eccentric shaft. According to the experimental results of the inventors of the present invention, a vibration motor having an eccentric shaft was most suitable to be applied to a micro-current and vibration providing mechanism when price and performance were compared.

The antenna 117 and the wireless communication module 115 are modules for transmitting and receiving data through wireless communication with an external device. For example, Bluetooth low energy (hereinafter, BLE) may be used for wireless communication, and the wireless communication module 115 implements modulation and demodulation for BLE communication in hardware or software. The power control module 120 is a module that converts unstable power supplied from the connection terminal unit 13 into stable power. As shown in FIG. 9 , the power control module 120 is shown as a separate configuration from the control unit 110 , but when the control unit 110 is implemented using a CPU chip with good performance, the wireless communication module 115 and the power supply It goes without saying that the control module 120 function can also be provided, so that it can be integrated into one piece of hardware (chip). Control data may be transmitted from an external device through the wireless communication module 115 , and the received control data is stored in the control unit 110 and then controls each vibration element.

After receiving control data through the wireless communication module 115 or the USB terminal, the control unit 110 determines whether the control data is for controlling the vibration element or control data for generating a microcurrent, and controls the vibration element In the case of control data for , a control signal for driving the vibrating element is generated and then transmitted to each vibrating element unit. The - power lines applied to the plurality of vibrating element units are configured to be connected to each other in common, and only the + power lines are individually connected to enable each vibrating element unit to be turned on/off individually.

The control unit 110 may be operated in such a way that various vibration patterns for driving a plurality of vibration elements are stored in advance, and a manipulation signal or control data for selecting one of the stored vibration patterns from an operation mode switch or an external device is input. As the vibration pattern, for example, 1) a first vibration pattern that applies vibration only to vibration elements disposed around the eyes, 2) a second vibration pattern that vibrates all vibration elements at the same time, and 3) sequentially vibrates the vibration elements one by one There may be a third vibration pattern, etc. When receiving control data from an external device via wired or wireless, the control unit 110 receives control data for controlling each vibration element from an external device instead of using a previously stored vibration pattern, interprets it, and controls each vibration element. Of course, it can be turned on/off.
