Description

Technical Field

[0001] The present invention relates to an electrolysis tube, and more specifically, to an electrolysis tube for progressively electrolyzing water to generate microbubbles. Background Technology

[0002] Currently, nano- and microbubble water is expected to be used in various fields such as food (sterilization) and beverages, cosmetics, liquid crystal manufacturing, medical applications (sterilization, cell storage, antibacterial effects), aquatic plant cultivation (dissolved oxygen production facilities, growth promotion), electronic device substrate cleaning, and reducing frictional resistance of marine vessels. Typically, microbubbles are generated by applying voltage to induce discharge between the cathode and anode.

[0003] Various nanobubble manufacturing devices with different configurations are being proposed. Japanese Patent Application Publication No. 2013-34958 discloses a method for manufacturing nanobubbles by splitting a liquid, mixing it with gas on one side of the split to generate microbubbles, then converging the liquid and supplying it to a plate with holes and a collision plate placed close to it.

[0004] This invention discloses a device for skin cleansing by miniaturizing an electrolytic tube that generates microbubbles and applying it to skin beauty. Skin cleansing or washing the face is important in skin management because, compared to the past, skin is exposed to various pollutants more frequently. Although invisible to the human eye, various pollutants exist in the atmosphere, including fine and ultrafine particles that may not be easily removed by water through simple methods such as hand washing.

[0005] The various beneficial substances applied to the skin daily to treat, protect, and improve its condition can only achieve their best results if removed at the appropriate time after being applied through various methods. Proper cleansing is essential to avoid adverse effects on the skin. Substances left on the skin for extended periods without proper cleansing can combine with environmental pollutants, causing adverse effects and making cleansing difficult.

[0006] In particular, face washing, as a process of cleansing the face, needs to be done more carefully due to the characteristics of facial skin. In order to clean effectively and safely, a variety of electrical, chemical and physical methods have been developed so far, but in the long run, there are not many methods that can clean safely and effectively without damaging the skin.

[0007] The utility model disclosed in Korean Patent No. 10-0787874, "Skin Management Device," discloses a form of beauty massage instrument equipped with such multiple functions. It can selectively generate ultrasound, infrared rays, ultraviolet rays, etc., to achieve beauty effects through sterilization, treatment, stimulation of endocrine glands, and improvement of blood circulation. However, its actual efficacy and theoretical basis are still insufficient.

[0008] The process of forming microbubbles is complex, and the miniaturization of the devices is difficult. This aligns with consumers' desire to receive beauty treatments or procedures at home at a reasonable price and at the desired time, which would otherwise require a significant investment of time and money. Self-administered beauty techniques and cutting-edge beauty instruments are constantly being developed, but so far, the technological sophistication of these products has not yet met the expectations of users accustomed to the effects of traditional professional massage.

[0014] Technical issues

[0015] The purpose of this invention is to provide an electrolysis tube that gradually electrolyzes water to generate microbubbles.

[0016] Another object of the present invention is to provide an electrolytic tube in which, as water flows in from one end of an electrode and flows out from the other end of the electrode to the outside, the inflowing water is gradually electrolyzed between a pair of electrodes, thereby generating microbubbles.

[0017] Technical solution

[0018] To achieve the above objectives, the present invention provides an electrolysis tube, comprising: an inlet 46 for supplying water; a moving tube 41 for moving the water supplied through the inlet 46 a predetermined distance; an outlet 48 for discharging the water moving through the moving tube 41; and a pair of electrodes 42, each consisting of a first electrode 43 and a second electrode 44, the first electrode 43 and the second electrode 44 being positioned opposite each other on both sides of the path of the water moving through the moving tube 41, and applying a voltage to the moving water to gradually electrolyze the water moving through the moving tube 41 to generate microbubbles.

[0030] The present invention will now be described in detail with reference to the accompanying drawings. In the drawings, for ease of explanation, some constituent elements may be shown enlarged or reduced compared to their actual dimensions. Furthermore, in the description of the present invention, specific descriptions of well-known general functions or configurations will be omitted.

[0031] Figure 1 This is a diagram illustrating an electrolytic tube according to an embodiment of the present invention. Figure 2 This is a diagram illustrating the structure of an electrolytic tube including electrodes according to an embodiment of the present invention; as shown. Figure 1 and Figure 2As shown, the electrolysis tube 40 includes: an inlet 46 for supplying water; a moving tube 41 for moving the water supplied through the inlet 46 a predetermined distance; an outlet 48 for discharging the water moving through the moving tube 41; and a pair of electrodes 42, each consisting of a first electrode 43 and a second electrode 44, which are positioned opposite each other at a predetermined interval on both sides of the path of the water moving through the moving tube 41. A voltage is applied to the moving water to progressively electrolyze it and generate microbubbles. The electrolysis tube 40 is cuboid in shape and is a microbubble generator capable of electrolyzing a portion of the water supplied from the inlet 46 to generate microbubbles.

[0032] Water supplied from the inlet 46 of the electrolysis tube 40 flows along the moving tube 41. At this time, a portion of the water is electrolyzed to generate microbubbles through a pair of electrodes 42 located inside the moving tube 41, thereby forming water including the microbubbles.

[0033] Specifically, water supplied from the inlet 46 flows along the moving pipe 41, and a portion of the water moving through the moving pipe 41 of the electrolysis tube 40 moves between the first electrode 43 and the second electrode 44. When a voltage is applied to the first electrode 43 and the second electrode 44, a portion of the water moving between them undergoes electrolysis. Thus, the water moving through the moving pipe 41 is gradually electrolyzed to generate microbubbles. Therefore, water supplied from the inlet 46 of the electrolysis tube is electrolyzed until it is discharged through the outlet 48, thereby gradually generating microbubbles, and water including the microbubbles is discharged through the outlet 48 of the electrolysis tube 40.

[0034] The pair of electrodes 42 can be accessed via module cap 47 (see...) Figure 3 The first electrode 43 and the second electrode 44 are fixed and connected to the moving tube 41. Specifically, the moving tube 41 has a module cap 47 inserted and connected to its lower part. When the first electrode 43 and the second electrode 44 are placed inside the moving tube 41, the module cap 47 is connected to the lower part of the moving tube 41, and the first electrode 43 and the second electrode 44 are fixed inside the moving tube 41.

[0035] The pair of electrodes 42 are guided by an inner fixed guide 45 (see...). Figure 1 (This could be a fixed guide rail, etc.) to make it easy for the electrode 42 fixed inside the moving tube 41 to be connected to the power supply, and the fixed guide 45 can be structurally modified in various ways.

[0036] Figure 3 This is a diagram illustrating the moving tube of an electrolytic tube according to an embodiment of the present invention; as shown. Figure 3As shown, during the process of water supplied from the inlet 46 being discharged through the outlet 48, the distance the water moves through the moving tube 41 is affected by the length t of the first electrode 43 and the second electrode 44 located inside the moving tube 41, so that the water can be gradually electrolyzed to generate microbubbles.

[0037] Water moving through the moving tube 41 moves along the length of the electrode 42. That is, water supplied from the inlet 46 flows into one end of the electrode 42 (the lower end of the electrode 42), is gradually electrolyzed between the pair of electrodes 42, and flows out (discharges) from the other end of the electrode 42 (the upper end of the electrode 42). One end (the lower end) of the first electrode 43 and the second electrode 44 is located near the inlet 46, allowing water supplied from the inlet 46 to flow in; the other end (the upper end) of the first electrode 43 and the second electrode 44 is located near the outlet 48, allowing microbubbles generated by the electrolysis to flow out from the outlet 48.

[0038] Therefore, the distance the water moves through the moving pipe 41 is substantially the same as the length t of the first electrode 43 and the second electrode 44 to which a voltage is applied. "Substantially the same" means that the length t of the first electrode 43 and the second electrode 44 to which a voltage is applied can be 90% or more, preferably 95% or more, and more preferably 100% of the distance the water moves through the moving pipe 41. Therefore, the length t of the first electrode 43 and the second electrode 44 located within the moving pipe 41 can be 90% or more, preferably 95% or more, and more preferably substantially the same as the length from the inlet 46 to the outlet 48 of the moving pipe 41.

[0039] The length of the moving tube 41 of the electrolysis tube 40, that is, the length t of the first electrode 43 and the second electrode 44 that apply voltage to the water moving through the moving tube 41, can be adjusted. In other words, the length of the moving tube 41 can be manufactured to a desired length. Thus, the size of the electrolysis tube 40 can be adjusted, allowing it to be manufactured not only as an ultra-miniature electrolysis tube but also as a larger one, suitable for various applications, such as household cleaning equipment, water purifiers, and water softeners.

[0040] If the overall area, including the lengths of the first and second electrodes, is large, and the distance between the opposing first and second electrodes is narrow, the electrolysis efficiency is high, and more microbubbles can be generated. However, the current consumption applied to the first and second electrodes increases dramatically, and in order to improve electrolysis efficiency through the generated microbubbles, the metal electroplated on the first and second electrodes is finely abraded. Over time, electrode oxidation may occur rapidly through the damaged areas. This phenomenon leads to a decrease in electrolysis performance, ultimately resulting in a significant reduction in electrode durability. Therefore, to ensure high electrolysis efficiency and prevent a significant decrease in electrode durability, appropriate specifications are required, such as the length and area of ​​the first and second electrodes, and the distance between them.

[0041] While various methods for generating microbubbles are known, the electrolytic tube of this invention generates microbubbles by utilizing water discharge through electrode plates. This water discharge utilizes a powerful discharge effect to electrolyze water molecules into hydrogen and oxygen ions, and this process can be continuously generated for skin cleansing. During the smooth discharge of bubbles generated during water discharge through the space between the anode and cathode electrodes, water discharge occurs throughout the entire region between the two electrodes. This water electrolysis, which enables the active electrolysis of water molecules, generates microbubbles.

[0042] Electrolysis is the process of forcibly separating substances that do not naturally separate into anions and cations in an aqueous solution into anions and cations using electricity. In particular, the electrolysis of water can produce Brown's gas, a mixture of oxygen and hydrogen in a 1:2 ratio.

[0043] These microbubbles typically have a size of less than 50 μm, resulting in very low buoyancy and a slow rising speed of approximately 3 mm / min, allowing them to remain submerged in water for extended periods. Consequently, water with a large number of microbubbles exhibits a high dissolved oxygen content. Surface tension acts on the surface of the microbubbles generated in the water, leading to an increase in internal pressure (self-pressurization effect) within the shrinking bubbles. This effect allows the increased internal pressure to persist for a longer period, and the gas, due to the increased pressure from microbubbling, can efficiently enter the water, resulting in a high gas dissolution rate. Based on these effects, the high gas dissolution rate, the electrostatic attraction of organic matter, and the energy generated upon disappearing all contribute to a bactericidal and cleansing effect, making microbubbles ideal for skin cleansing.

[0044] Although the microbubbles remain in water for a longer time than conventional bubbles, the design should minimize the interval between the time of generation by the microbubble generator and the time of application to the skin, as the effect of microbubbles should be fully applied to the skin and effectively contribute to cleansing. To improve conductivity, electrolytes such as NaCl may need to be added during electrolysis, but with the design and electrodes of this invention, pure water can be electrolyzed.

[0045] Figure 4 This is a photograph illustrating an example of an electrode that can be used in an electrolytic tube according to an embodiment of the present invention. Figure 5 This is a diagram illustrating the electroplated layer of an electrode that can be used in an electrolytic tube according to an embodiment of the present invention. Figure 4 and Figure 5 As shown, the first electrode 43 and the second electrode 44 refer to the anode and the cathode, respectively. The first electrode 43 and the second electrode 44 have a plate-like shape extending in one direction. If necessary, they can have a mesh structure with multiple openings formed on the plate-like shape.

[0046] The first electrode 43 and the second electrode 44 can be electrode plates on titanium metal 42a plated with platinum group metal 42b, which has high electrolytic catalytic efficiency. For efficient microbubble generation, the electrode 42 is preferably plated with platinum group metal 42b, which has high electrolytic catalytic effect, on titanium metal 42a, which has strong corrosion resistance.

[0047] For the pair of electrodes 42 used in the electrolytic tube 40, taking into account factors such as electrolytic catalytic efficiency, short electrode life caused by the separation of metal ions during discharge, and the possibility of harmful chemical changes during oxidation, an electrode with platinum group metal 42b electroplated on a titanium electrode 42a is adopted. Furthermore, a mesh structure with multiple openings formed on a plate shape can be adopted to further maximize efficiency.

[0048] like Figure 5 As shown, to improve the durability of the electrode 42, two or more electroplating processes can be performed. A second electroplating process using titanium metal 42a can be performed on the electrode where platinum group metal 42b is plated on the titanium metal 42a. The titanium metal 42a and platinum group metal 42b can be plated at the same thickness, and preferably, the thickness C of the plating of the titanium metal 42a and platinum group metal 42b is between 0.1 μm and 10 μm. Exceeding this plating thickness range will reduce the economic efficiency of the product.

[0049] The electrolysis tube 40 combines a moving tube 41, which serves as the moving path for water supplied from the inlet 46, and a pair of electrodes 42 that apply voltage to the moving water and gradually electrolyze the water moving through the moving tube 41 to generate microbubbles. This allows the water supplied from the water tank to be gradually electrolyzed until it is finally discharged through the outlet 48, thereby continuously generating microbubbles.

[0050] The electrolytic tube of the present invention can be applied to a microbubble cleanser for cleaning a user's skin, as needed. The following is a description of a microbubble cleanser using the electrolytic tube. Figure 6 and Figure 7 These are, respectively, a perspective view of the external shape and a sectional view along the length of a microbubble cleaner according to an embodiment of the present invention. Figure 6 and 7 As shown, a microbubble cleaner with an ultra-miniature electrolytic tube according to the present invention includes: a water tank 20, which is attached to one end of a housing 10, containing pure water as a medium for generating and supplying microbubbles; a pump 30, located above the water tank 20, which draws water contained in the water tank 20 and delivers the drawn water at a predetermined pressure by spraying the drawn water through the electrolytic tube 40 onto the user's skin; and an electrolytic tube 40, located at one end of the pump 30, which electrolyzes the water supplied from the pump 30 to generate microbubbles and supplies the water with generated microbubbles to the user's skin; and further includes a vibration drive unit 50, a control unit 60, and a vibration cleaning unit 70.

[0051] The outer casing 10 can be configured as a generally cylindrical shape so that the user can hold it by hand or attach a handle to use the microbubble cleaner, and the water tank 20, pump 30, electrolysis tube 40, vibration drive unit 50, control unit 60, vibration cleaning unit 70, etc., can be accommodated inside the outer casing 10 or installed at one end of the outer casing 10. For example, Figure 8 This is an exploded view of a microbubble cleaner according to an embodiment of the present invention. Figure 8 As shown, the vibrating cleaning unit 70 is attached to the upper end of the housing 10, the water tank 20 is attached to the lower end, and the pump 30, electrolysis tube 40, vibration drive unit 50, and control unit 60 can be installed inside. The upper end of the housing 10 further includes a through hole 14, which exposes the outlet 48 of the electrolysis tube 40, through which water containing microbubbles generated in the electrolysis tube 40 is discharged to the user's skin. The button located in the middle of the housing 10 is for driving the microbubble cleaner. The housing 10 can be made of a rigid synthetic resin such as plastic, a synthetic resin with predetermined elasticity such as silicone or rubber, or a common material such as metal.

[0052] The water tank 20, which holds water as a medium for generating and supplying microbubbles, is attached to one end of the outer casing 10, for example, detachably attached to the lower end. The water used as the medium is preferably pure water, rather than a specially manufactured solution.

[0053] The upper part of the water tank 20 is provided with a water cup nozzle. The water cup nozzle and the water tank 20 can be combined by conventional methods, such as forming multiple grooves and engaging them by rotation, or by fitting. The upper part of the water cup nozzle may further include a joint for connection with the pump 30, and a nozzle tube connected to the first flow path tube 31 via the tube 34 of the pump 30 (described later). That is, water contained in the water tank 20 under a specified pressure of the pump 30 rises and moves to the pump 30 through the nozzle tube.

[0054] The pump 30 draws water from the water tank 20 and delivers the drawn water at a predetermined pressure by spraying it through the electrolysis tube 40 onto the user's skin, thereby pushing the water towards the user's skin. That is, water contained in the water tank 20 is supplied from the water tank 20 to the electrolysis tube 40 by the metering pump 30. However, Figure 2 The exploded view along the length direction does not specifically illustrate the connection method of the water tank 20, pump 30, and electrolysis tube 40, but the connection structure will be described in the accompanying drawings later. The pump 30 can be fixed inside the outer casing 10 by means of a predetermined bracket.

[0055] Figure 9 This is a cross-sectional view illustrating a pump structure usable in a microbubble cleaner according to an embodiment of the present invention. Figure 9 As shown, the central part of the device is equipped with a pipe-connected metering pump (hereinafter also referred to as a tubular pump), as illustrated in the example below. The pump 30 includes a first flow path pipe 31 connected to the water tank 20 and a second flow path pipe 32 connected to the electrolysis tube 40. In this case, when air is supplied from the pump 30 to the water tank 20 through the first flow path pipe 31 at a predetermined pressure, water drawn from the water tank 20 through the first flow path pipe 31 is transported to the electrolysis tube 40 through the second flow path pipe 32 at a predetermined pressure. Figure 4 The arrow pointing from (A) to (B) indicates the direction of water flow.

[0056] Figure 10 It is shown Figure 9 The diagram shows the internal structure of the pump; as shown. Figure 10As shown, the pump 30 is a pipe-driven quantitative pump, which may include: a motor 33 that drives the pump 30; a plurality of rotating gears located at one end of the motor 33 and driven to rotate when driven by the motor 33; and a pump drive unit including a pipe 35 surrounding the outer peripheral surface of the plurality of rotating gears for moving water drawn from the water tank 20. The pipe 35 is a hollow tube shape, and water moves inside the pipe 35. The material of the pipe 35 can be used without restriction.

[0057] The pump 30 is driven, for example, by a motor 33 within the pump 30. When the motor 33 is driven, its rotating shaft causes the rotating gear 34 to rotate, generating a predetermined pressure inside the pipe 35. Water contained in the water tank 20 is then drawn towards the pump 30 via a first flow path pipe 31 connected to the nozzle pipe of the water tank 20. Depending on the rotation direction of the rotating gear 34, the water drawn into the water tank 20 moves within the pipe 35, allowing it to be delivered to the electrolysis tube 40 via a second flow path pipe 32 connected to the inlet 46 of the electrolysis tube 40 (described later).

[0058] The metering pump used as the pump 30 can precisely control the amount of fluid flowing in and can move liquids (e.g., water) using pipes 35 located inside the pump 30 without concerns about contamination. Based on this principle, during the supply (transport) of water, the water flowing through the pipes 35 inside the pump 30 is not contaminated by the drive device, and clean water suitable for facial cleansing can be supplied, thus enabling a clean facial cleansing.

[0059] The electrolytic tube 40 is the same as previously disclosed. Figures 1 to 5 As shown above, and referring to the same description again, the electrolysis tube 40 used in the microbubble cleaner of the present invention is the same as the electrolysis tube 40 disclosed above.

[0060] The electrolysis tube 40 is in the shape of a long cuboid and is an ultra-miniature microbubble generator capable of electrolyzing a portion of the water supplied from the pump 30 to generate microbubbles. It is connected to the pump 30 and includes: an inlet 46 for supplying water contained in the water tank 20 through the pump 30; a moving tube 41 for moving the water supplied through the inlet 46 a predetermined distance; an outlet 48 for discharging the water moving through the moving tube 41; and a pair of electrodes 42, which are composed of a first electrode 43 and a second electrode 44, which are positioned opposite each other at a predetermined interval on both sides of the movement path of the water moving through the moving tube 41. A voltage is applied to the moving water to gradually electrolyze the water moving through the moving tube 41 to generate microbubbles.

[0061] The water inlet 46 is connected to the pump 30, specifically to one end of the pipe 35 (first flow path pipe 31) located inside the pump 30, so that water contained in the water tank 20 is supplied (drawn) to the electrolysis tube 40 under a predetermined pressure. The water outlet 48 is located at the same position as the through hole 14 of the outer casing and the through hole 74 of the vibrating cleaning part described later, and can discharge (spray) water that generates microbubbles onto the user's skin.

[0062] As the electrode 42, a titanium electrode plated with a platinum group metal with high electrolytic catalytic efficiency is preferably used. The electrode 42 is electroplated with a metal with high electrolytic catalytic effect; for the durability of the electrode 42, a titanium electrode with strong corrosion resistance is used, and it can be electroplated with a platinum group metal with high electrolytic catalytic efficiency for two or more layers.

[0063] The first electrode 43 and the second electrode 44 are positioned opposite each other at a predetermined interval on both sides of the moving path of the water moving through the moving tube 41; when a voltage is applied to the moving water, electrolysis gradually occurs in the interval between the first electrode 43 and the second electrode 44, generating microbubbles.

[0064] Although the microbubbles remain in water for a longer time than ordinary bubbles, the distance the water moves through the moving tube 41 is substantially the same as the length t of the first electrode 43 and the second electrode 44 to which the voltage is applied, so as to minimize the interval between the time of generation from the microbubble generator and the time of application to the skin.

[0065] Specifically, the first electrode 43 is electrically connected to an external power source, such as a battery 52, and the second electrode 44 is also electrically connected to an external power source. More specifically, when current is supplied from the external power source to the first electrode 43 and the second electrode 44, water discharge occurs in the entire region between the two electrodes at a predetermined interval, resulting in active electrolysis of water molecules and the generation of microbubbles. Furthermore, a portion of the water electrolyzed in the electrolysis tube 40 is heated, enabling the application of warm water rich in microbubbles to the user's skin.

[0066] According to the electrolysis tube 40 of the present invention, water drawn from the water tank 20 is immediately (instantly) electrolyzed inside the moving tube (flow path tube) 41 that moves to the skin of the practitioner by means of the pump 30, continuously and abundantly generating microbubbles, thereby eliminating the need for an additional bubble generation chamber.

[0067] Furthermore, two electrodes are arranged face-to-face at a close interval in the narrow moving tube 41 (flow path tube) of the electrolysis tube 40 to generate microbubbles. At the same time, the bubbles formed by the vaporization of water through partial discharge heat will also cause discharge under a weak electric field, thereby inducing a synergistic effect of microbubble generation.

[0068] The microbubble cleaner with the ultra-miniature electrolytic tube of the present invention can have a system capable of sensing the amount of liquid passing through the electrolytic tube 40 by various methods, thereby preventing overcurrent or overheating in advance. For example, a capacitance sensor or an IV converter can be used to measure the amount of water or determine the presence or absence of water.

[0069] The vibration drive unit 50 can drive the vibration cleaning unit 70 (described later) by conventional methods such as motor drive or ultrasonic drive. The vibration drive unit 50 includes a built-in battery 52 located inside the housing 10 and a vibration motor 54 connected to the upper part of the built-in battery 52. ​​The vibration drive unit 50 can be fixed inside the housing 10 by a predetermined bracket.

[0070] Driven by the battery 52, the vibration motor 54 generates vibration as it rotates. The vibration motor 54 is preferably capable of rotating 180°. The intensity of the vibration can be adjusted according to the rotational speed of the vibration motor 54. Thus, the vibration cleaner of the present invention operates using a built-in battery 52 and can provide a vibration effect, thereby improving cleaning performance and user satisfaction.

[0071] The control unit 60 is electrically connected to the battery 52 and controls components (e.g., pump 30, electrolysis tube 40, vibration drive unit 50, vibration cleaning unit 70, etc.) according to a set program. In particular, the control unit 60 can prevent overcurrent or overheating in advance by setting voltage, current, running time, etc., and can control (adjust) the generation of microbubbles.

[0072] The vibrating cleaning part 70 is located at one end of the housing 10, and may have a cross-sectional shape substantially similar to that of the housing 10 to cover the open side of the housing 10. The vibrating cleaning part 70 is the part that comes into contact with the user's skin and cleans the skin by friction, and may have a substantially flat surface morphology to allow it to contact the user's skin over a wide area.

[0073] Specifically, although the vibrating cleaning section 70 is not shown in the figure, it also includes a vibrating plate capable of vibrating in the up and down directions, and a cleaning pad 72 formed on the upper part of the vibrating plate.

[0074] The vibrating plate is not particularly limited in its shape or material and can be made of flexible materials such as rubber and silicone.

[0075] The cleansing pad 72 contacts and rubs against the skin during its up-and-down vibration to perform a skin cleansing function. The cleansing pad 72 may include a brush, protrusions, a sponge, a towel, or other similar device for contacting and rubbing the skin to clean it.

[0076] The cleaning pad 72 may be integrally formed with the vibrating plate, or bonded by an adhesive, or combined by conventional bonding methods such as physical fitting. The cleaning pad 72 and the vibrating plate of the vibrating cleaning unit 70 include a through hole that exposes the outlet 44 of the electrolysis tube 40 to the outside.

[0077] According to the electrolytic tube of the present invention, since a pair of electrodes 42 can be disposed close to each other, it is easy to miniaturize and suitable for use in small-sized skin beauty instruments. Furthermore, the microbubble cleanser according to the present invention, utilizing the ultra-miniature electrolytic tube 40 and the metering pump 30, electrolyzes water applied to the user's skin along a water path to the end, thereby generating abundant microbubbles, and can be used for cleansing by supplying the user's skin with water rich in said microbubbles.

[0078] Although the present invention has been described above with reference to the accompanying drawings and exemplary embodiments, the present invention is not limited to the contents shown in the drawings and the above embodiments. For ease of understanding, reference numerals are used in the following claims, but the scope of the following claims is not limited to the reference numerals and contents shown in the drawings, and should be interpreted as covering all variations, equivalent configurations and functions of the exemplary embodiments.
