[Problem to be solved by the invention]

However, in the hair growth brush of the prior art, because the conductive bristles that flow current to the skin are exposed on the surface, the conductive bristles will swell and worsen due to the influence of chemicals such as hairdressing products and sweat. There will be a problem of poor conductivity. [Technical means to solve the problem]

Because, as the skin stimulation brush of the present invention for solving the above-mentioned problems, it is equipped with: a housing, which constitutes a brush handle and a pin base provided at one end of the brush handle; a circuit, which is accommodated in the aforementioned Inside the casing; and a plurality of pins for the skin stimulating brush, which are protrudingly arranged on the aforementioned pin base; and the skin stimulating brush formed is characterized by: The aforementioned needle pin for a skin stimulation brush has: a metal base member connected to the aforementioned circuit so as to be able to conduct electricity from the aforementioned circuit; Its base end portion; an electrode member, which is connected to the opening on the front end side of the aforementioned barrel member, and whose front end is exposed from the opening; and a metal shaft, which is inserted through the barrel of the aforementioned barrel member through a gap. inside, and is used to connect the aforementioned base member and the aforementioned electrode member.

According to the above-mentioned configuration, because the metal shaft system for applying current to the electrode member is inserted into the barrel of the barrel member, the metal shaft will not directly contact the skin, as well as the sebum, moisture, and shampoo attached to the body hair. , cosmetics, etc. In this way, corrosion of the metal shaft serving as a current path from the circuit to the electrode member can be suppressed, and deterioration in electrical conductivity can be suppressed over a long period of time.

Moreover, the said electrode member can also be manufactured so that it may have corrosion resistance.

In this case, by making the electrode member directly in contact with the skin to be corrosion-resistant, even if sebum, water, shampoo, cosmetics, etc. adhere to the electrode member, the electrode member will not be easily damaged. rust. In this way, corrosion of the electrode members can be suppressed, and deterioration of the conductivity of the electrode members can also be suppressed.

In addition, the aforementioned electrode member may be made of stainless steel, or may be made of copper, aluminum, silver, gold or an alloy.

In addition, the metal shaft may have flexibility capable of bending in the radial direction, and the barrel member may have elasticity capable of bending in the radial direction.

The "radial direction" here refers to the radial direction when the length direction of the pins for the skin stimulation brush is regarded as the axial direction. However, the present invention does not limit the shape of the metal shaft or barrel member to a cylindrical shape or a cylindrical shape.

In this case, both the barrel member and the metal shaft inserted inside the barrel of the barrel member can be bent radially. In this way, when the pins for the skin stimulating brush are used, the pins for the skin stimulating brush can be bent radially in response to the force fed back from the skin to the pins for the skin stimulating brush. Therefore, the pins of the skin stimulating brush can achieve a massage effect due to the elasticity of the bent state of the pins when pressed against the skin. In addition, by combining with the above-mentioned constituent elements, the pin for a skin stimulation brush can be provided with the reliable conductivity achieved by the metal shaft, and it can be used to suppress the interaction with sebum, moisture, shampoo, cosmetics, etc. The effect of the time-dependent deterioration of electrical conductivity caused by contact with other materials.

Also, the aforementioned metal shaft is preferably constituted by a spring. As for the spring, a long axis-shaped spring is preferable, and specifically, applicable examples include leaf springs, coil springs, and the like. The aforementioned metal shaft is a coil spring that pushes the aforementioned electrode member toward the front end side, and the aforementioned electrode member may also be arranged such that when a force acting toward the proximal end side is applied to the aforementioned electrode member, the aforementioned electrode member can be pushed It is urged toward the base end side against the elastic thrust of the aforementioned coil spring.

In this case, the electrode member can be pushed in toward the base end side against the biasing force of the coil spring. Therefore, when the skin stimulation brush comes into contact with the skin with the pins, the electrode member can be pushed toward the base end side by the pressure generated by the contact with the skin. Furthermore, in a state where the electrode member is urged toward the proximal end side, the coil spring also applies a spring urging force toward the distal end side to the electrode member. In this way, when the electrode member is pressed against the skin, the shock generated by the collision between the electrode member and the skin can be alleviated. In this way, the force applied by the user can be easily adjusted.

In addition, the barrel member may be made flexible in the longitudinal direction, and the barrel member may be compressed in the longitudinal direction when the electrode member is pushed toward the base end side.

In this case, when the electrode member is urged toward the base end side, the barrel member is compressed in the length direction. Furthermore, the barrel member is flexible, so when the electrode member is pushed toward the base end, in addition to the elastic thrust of the coil spring, there is also the restoring force of the barrel member itself after being compressed. front side. Therefore, even if the user of the pin for a skin stimulation brush strongly presses the electrode member against the skin, the skin will not be accidentally injured. Furthermore, by using the aforementioned elastic thrust and restoring force, it is possible to ensure the reliable contact between the electrode member and the skin, and to give the user a comfortable and stimulating pressing feeling.

In addition, the above-mentioned barrel member can also be made to have water resistance.

In this case, by making the barrel member water-resistant, penetration of moisture into the barrel interior of the barrel member can be suppressed. Therefore, it is possible to suppress moisture from coming into contact with the metal shaft inserted inside the cartridge. Thereby, the corrosion of the metal shaft can be suppressed, and further, the deterioration of the conductivity of the metal shaft can be suppressed.

Also, the above-mentioned barrel member may be formed of silicon rubber.

In this case, silicone rubber is safe for the human body in addition to being water resistant. Therefore, you can use pin pins for skin irritation brushes with peace of mind.

In addition, the aforementioned circuit may be fabricated so that a low-frequency current can be applied from the aforementioned base member to the aforementioned electrode member via the aforementioned metal shaft.

In this case, the low-frequency current applied to the base member will flow through the metal shaft to make the electrode member conductive. Therefore, when the conductive electrode member comes into contact with the skin, a low-frequency current can be applied to the skin. Also, the low-frequency current has the property of being able to act near the surface of the skin. Therefore, electrical stimulation can be given by targeting the vicinity of the surface of the skin. [Effect of Invention]

According to the present invention, since the metal shaft does not come into direct contact with sebum, moisture, shampoo, cosmetics, etc. adhering to the skin or body hair, corrosion of the metal shaft can be suppressed. Therefore, deterioration of the conductivity of the metal shaft can be suppressed. Therefore, it is possible to provide a skin-irritating brush capable of suppressing deterioration of conductivity. Furthermore, it can meet the needs of users who want to maintain the intensity of electrical stimulation.

Also, when the barrel member is made as a barrel having elasticity in the radial direction and flexibility in the longitudinal direction, for the user of the skin stimulation brush, even if the electrode member is strongly pressed against the skin, , and will not allow the skin to be accidentally damaged. Furthermore, by using the aforementioned elastic thrust and restoring force, it is possible to ensure the reliable contact between the electrode member and the skin, and to give the user a comfortable and stimulating pressing feeling.

Furthermore, according to the present invention, the low-frequency current applied to the skin from the electrode member can increase the blood flow of the skin to activate the metabolism of cells. Stimulating the skin of the part where the hair grows in this way can suppress hair loss. In addition, as long as the facial skin is stimulated, an immediate skin lift-up effect can be exerted, which can improve the skin condition before makeup and make it easier to apply makeup.

In addition, the above-mentioned lifting effect of the skin can also exert a skin tightening effect on the skin other than the face, and can suppress the sagging of the skin.

Hereinafter, the action and effect of the skin stimulation brush 1 will be described in accordance with the usage procedure of an example of the skin stimulation brush 1 according to this embodiment.

First, the user of the skin stimulating brush 1 must turn on the power supply (not shown) of the skin stimulating brush 1 disposed in the casing 2 .

In the skin stimulation brush 1 shown in the example of this embodiment, a current flows through the circuit 6 when the power is turned on. In addition, the base member 20 can be electrically connected to the circuit 6 to the circuit 6 . More specifically, the base pin 21 of the base member 20 abuts on the through hole 7 and is inserted into the through hole 7 . In this way, the current flowing through the circuit 6 can be used to make the base member 20 conduct electricity. Second, the metal shaft 40 also abuts against the already conductive base member 20 . In this way, current flows from the base member 20 to the metal shaft 40 . Furthermore, the metal shaft 40 abuts against the electrode member 50 . In this way, the current flowing through the metal shaft 40 will flow to the electrode member 50 . Accordingly, current flows to the electrode member 50 .

Also, in the skin stimulating brush 1 shown in the example of this embodiment, if the circuit 6 is made to apply a low-frequency current to the base member 20, for example: the circuit 6 has a low-frequency current generator or a low-frequency modulator. , that is, a low-frequency current is applied to the base member 20 . In this way, low-frequency current flows from the base member 20 to the electrode member 50 via the metal shaft 40 .

Next, massage the electrode member 50 against the skin with the conductive skin stimulation brush 1 . At this time, the electrode member 50 exposed from the front end of the barrel member 30 is in contact with the skin to apply electrical stimulation and pressure stimulation to the skin.

The skin to be treated, in addition to the scalp, the skin in the body can also be used as the target of treatment. The hair that grows on the scalp and the body hair that grows on the skin of the body may have sebum, moisture, shampoo, cosmetics, etc. attached to them. These fluids have degraded conventional skin irritation brushes by reducing their conductivity. That is, the conductive bristles used in conventional skin stimulation brushes are formed of metal or conductive resin. Conventionally, when skin is stimulated using such conductive bristles, the following problems have occurred. When the skin is irritated with conductive bristles made of metal, the metal used to form the conductive bristles is corroded by substances such as moisture adhering to the skin, resulting in a problem of lowered conductivity. In addition, when using conductive bristles made of conductive resin, the resin absorbs moisture or the like and deteriorates, which further causes a problem that the conductivity of the conductive resin decreases. These problems all lead to a shortened lifespan of the skin stimulating brush itself, and therefore cannot fully meet the needs of users who want to maintain the intensity of electrical stimulation for a long time.

Therefore, in the skin stimulating brush 1 shown in the example of this embodiment, the metal shaft 40 as the path of the current is inserted inside the cylinder of the cylinder body member 30, so that the metal shaft 40 does not directly contact the skin attached to it. contact with sebum, moisture, shampoo, cosmetics, etc. on the skin or body hair. Therefore, corrosion of the metal shaft 40 serving as a current path from the circuit 6 to the electrode member 50 can be suppressed, and deterioration of conductivity after long-term use can be suppressed. Furthermore, the strength of electrical stimulation to the skin can be maintained for a long time, not only the metal shaft 40, but also the life of the whole skin stimulation brush 1 can be extended.

Also, it can be prevented that only a part of the pins 10 for the skin stimulating brush 10 installed in the skin stimulating brush 1 shown in the example of this embodiment become conductive due to adhesion of cosmetics or the like. Occurrence of deterioration The deterioration of the pin 10 for the skin irritation brush is inconsistent.

Furthermore, in the case where the barrel member 30 of the skin stimulation brush 1 shown in the example of this embodiment has water resistance, it is difficult for moisture to penetrate into the barrel of the barrel member 30 through which the metal shaft 40 is inserted. The metal shaft 40 will not come into contact with the liquid, and the effect of inhibiting the metal shaft 40 from being corroded is more significant.

Furthermore, when the barrel member 30 of the skin stimulation brush 1 shown in the example of this embodiment is formed of silicon rubber, the physical properties of silicon rubber can exert excellent water resistance, and the metal shaft 40 can be prevented from being corroded. . Furthermore, in the case where the barrel member 30 is made of silicone rubber, the barrel member 30 has elasticity that can bend in the radial direction. In addition, if the barrel member 30 is formed of silicone rubber, it has flexibility in the longitudinal direction as well.

Moreover, when the electrode member 50 of the skin stimulation brush 1 shown in the example of this embodiment has corrosion resistance, it can suppress that the electrode member 50 is corroded. Therefore, it is possible to suppress deterioration of the conductivity of the electrode member 50 .

Furthermore, in the case where the electrode member 50 of the skin stimulation brush 1 shown in the example of this embodiment is made of stainless steel, since the electrode member 50 has corrosion resistance, it is possible to suppress corrosion of the electrode member 50 and to suppress the loss of electrical conductivity. worse. In addition, when the electrode member 50 is made of stainless steel, the property that the passivation film regenerates can be utilized, and corrosion of the electrode member 50 can be suppressed for a longer period of time, and a decrease in electrical conductivity can be suppressed. Furthermore, the passivation film of the stainless steel is extremely thin, so the electrical stimulation effect of the electrode member 50 on the skin will not be hindered. Furthermore, when the electrode member 50 is made of stainless steel, the workability and strength of the electrode member 50 can be easily improved.

Also, in the case where the barrel member 30 and the electrode member 50 of the skin stimulating brush 1 shown in the example of this embodiment are connected to each other without a gap, it is possible to suppress the flow of liquid and moisture from between the barrel member 30 and the electrode member 50. into the inside of the barrel of the barrel member 30 . In this way, corrosion of the metal shaft 40 can be suppressed, and a decrease in electrical conductivity can be suppressed.

Also, in the case where the pin base 4 and the barrel member 30 of the skin stimulation brush 1 shown in the example of this embodiment are connected to each other without gaps, it is possible to suppress the flow of liquid and moisture from the barrel member 30 and the pin base 4 . enters the inside of the barrel of the barrel member 30 . In this way, corrosion of the metal shaft 40 or the base member 20 can be suppressed, and a decrease in electrical conductivity can be suppressed. In addition, when the connecting portion of the barrel member 30 and the electrode member 50 and the connecting portion of the barrel member 30 and the pin base 4 are tightly joined to each other without any gap, it is possible to suppress the entry of liquid and moisture into the barrel member. The inside of 30, especially, can prevent the reduction of the conductivity of the skin irritation brush 1, and can prolong the life of the skin irritation brush 1. In addition, such a structure can be easily constructed by using an elastic body member 30 such as silicon rubber.

In addition, in the case where the tip of the electrode member 50 of the skin stimulation brush 1 shown in the example of this embodiment is formed into a curved surface, a good touch can be obtained when the electrode member 50 comes into contact with the skin.

Next, the skin stimulation brush pin 10 of the skin stimulation brush 1 is pressed against the skin from a direction inclined to the skin surface.

In this case, when the metal shaft 40 of the skin stimulating brush 1 shown in the example of this embodiment has flexibility to bend in the radial direction, and the barrel member 30 has elasticity to bend in the radial direction, the barrel member 30 and the metal shaft 40 can be integrally bent radially. In this way, the skin is also pressed by the restoring force generated by the elasticity of the barrel member 30 itself, and a good massage effect can be obtained.

Furthermore, if the metal shaft 40 of the skin stimulating brush 1 shown in the example of this embodiment is made to have the second elasticity, in addition to the restoring force generated by the elasticity of the barrel member 30 itself, it will also The second restoring force generated by the second elasticity of the metal shaft 40 acts on the skin, so that the skin can be pressed more strongly. In this way, electrical stimulation can be applied to the skin and a good massage effect can be obtained. Also, for example, if the metal shaft 40 is formed by a spring, the aforementioned second elasticity can be obtained. Selection of the spring system: a long-axis spring is preferable, and specifically, a leaf spring or a coil spring is suitable as an example. In particular, a coil spring is particularly suitable because it can be easily attached to the electrode member 50 . Specifically, if the metal shaft 40 is a coil spring, as long as the coil spring is wrapped around the shaft-shaped part of the electrode member 50 that has been inserted into the front end opening 34, that is, the shaft portion 51, the electrode member 50 and the electrode member 50 can be easily completed. Connection of the metal shaft 40 . Also, as shown in FIG. 4 , when the metal shaft 40 is installed inside the barrel member 30 , it is better to keep a gap 36 between the inner surface 35 of the barrel member 30 . By keeping this gap 36, when the barrel member 30 bends in the radial direction, the metal shaft 40 and the barrel member 30 can be bent without contacting each other.

Next, the skin stimulation brush pin 10 of the skin stimulation brush 1 is pressed against the skin from above perpendicular to the skin surface.

In this case, if the metal shaft 40 of the skin stimulation brush 1 shown in the example of this embodiment is constituted by a coil spring, the electrode member 50 can be urged toward the base end against the elastic thrust of the coil spring. In this way, when the electrode member 50 presses the skin, the shock generated by the collision between the electrode member 50 and the skin can be alleviated. In this way, the user can easily adjust the force applied to the skin stimulating brush 1 . Also, in a state where the electrode member 50 is urged toward the proximal end side, the biasing force of the coil spring for the electrode member 50 is transmitted to the distal end side. In this way, the electrode member 50 can press the skin, and better massage can be achieved. Moreover, the structure of the electrode member 50 is not limited to the structure that is pushed toward the base end side together with the cylindrical body member 30 , for example: it may also be made such that the electrode member 50 is placed on one side in the front end opening 34 of the cylindrical body member 30 . Push while sliding toward the proximal side.

Furthermore, the barrel member 30 of the skin stimulation brush 1 shown in the example of this embodiment has flexibility in the longitudinal direction, and when the electrode member 50 is pushed toward the base end side, the barrel member 30 is also Squeezed in the longitudinal direction, at this time, in addition to the elastic thrust force applied by the coil spring, the restoring force toward the front end side of the compressed barrel member 30 also acts on the electrode member 50 . In this way, the contact between the skin and the electrode member 50 can be achieved more reliably, and stronger pressing stimulation can be obtained. In addition, in the skin stimulating brush 1 shown in this embodiment, when the barrel member 30 is squeezed, it is squeezed and shortened while expanding the inner diameter of the barrel. Therefore, the degree of shortening of the barrel member 30 can be increased, and A stronger pressing feeling can be obtained.

In addition, the operation and effect produced by the skin stimulation brush 1 shown as an example of this embodiment will be described.

According to the skin stimulating brush 1 shown in the example of this embodiment, the low-frequency current applied to the skin from the electrode member 50 increases the blood flow of the skin to activate the metabolism of cells. In this way, hair loss can be suppressed as long as the skin at the hair growth site can be stimulated. In addition, as long as the facial skin is stimulated, an instant skin lifting effect can be exerted, the skin condition before makeup can be improved, and makeup can be applied more easily.

In addition, the above-mentioned skin lifting effect can exert a skin tightening effect on the skin other than the face, and can suppress the sagging of the skin.

In the skin stimulation brush 1 shown in the example of this embodiment, the base end portion of the barrel member 30 is fixed by the inner surface of the housing 2 and the surface of the circuit 6 facing the housing 2 . Thereby, the pin 10 for skin stimulation brushes can be suppressed from being pulled out from the pin base hole 5 and falling off, or being pushed into the pin base hole 5 from occurring.

In addition, in the skin stimulating brush 1 shown in the example of this embodiment, the electrode member 50 is engaged with the electrode member 50 with the electrode fall-off preventing portion 52 engaged with the diameter-reduced portion 33 of the barrel member 30, so that the electrode member 50 can be prevented from coming off from the barrel member 30. The front end opening 34 falls off.

In addition, in the skin stimulation brush 1 shown in the example of this embodiment, the coil spring is sandwiched between the base member 20 and the electrode member 50 to be compressed. In this way, the stretching and restoring force of the coil spring can be accumulated, and the contact of the coil spring with the base member 20 and the electrode member 50 can be made more reliable.

Moreover, in the skin stimulation brush 1 shown in the example of this embodiment, the contact part of the metal shaft 40 and the electrode member 50 is fixed by the adhesive agent 60. As shown in FIG. Furthermore, the adhesive 60 can be used: room temperature vulcanizing rubber (RTV rubber) that can be adhered to silicone rubber. In this way, in addition to making the contact between the metal shaft 40 and the electrode member 50 more reliable, it is also possible to prevent the electrode member 50 from falling off from the barrel member 30 formed of silicone rubber.

Furthermore, if the adhesive 60 of the skin stimulating brush 1 shown in the example of this embodiment is a conductive adhesive, even if the metal shaft 40 is separated from the electrode member 50, the current can still flow through the adhesive. The agent 60 is still able to make the electrode member 50 conduct electricity.

Furthermore, according to the structure in which the base convex portion 23 of the skin stimulating brush 1 shown in the example of this embodiment is embedded in the base end portion of the coil spring, the positioning position of the base end portion of the coil spring is very certain, and the base member 20 The electrical connection to the coil spring is also assured.

In addition, the operation and effect mentioned above are only the operation and effect of the skin stimulation brush 1 shown as an example of this embodiment. Therefore, the technical scope of the present invention is not limited by the actions and effects of the present embodiment.
