Description

Tattoo device and needle roller for tattooing {NEEDLE ROLLER AND APPARATUS FOR TATTOO}

The present disclosure relates to tattoo devices and needle rollers for tattooing.

For example, scalp tattooing involves tattooing pores on areas of the scalp where hair is lacking or has disappeared, making the hair appear abundant and giving the visual effect of having hair roots.

To tattoo the scalp, either a dedicated needle or an electric tattoo device is used to injure the skin and inject a solution to stain the skin. The user tattoos the scalp by soaking a needle in a solution, puncturing the scalp at regular intervals, and repeating the process of injecting the solution.

In addition, the electric tattoo device has a structure in which the needle continuously reciprocates and mechanically vibrates at the tip of the device under the driving force of a motor, etc., allowing the user to conveniently perform the procedure without moving the needle relative to the skin. Accordingly, the user can tattoo the scalp at regular intervals while gradually moving the reciprocating needle to a desired location on the scalp.

However, the above-mentioned conventional scalp tattoo structure has a problem in that it is difficult for non-skilled people to properly use the needle or device, and the tattoo results vary greatly depending on the skill level. In addition, even if you are a skilled person, you have to dip the solution one by one and puncture the scalp one by one, making the work inconvenient, difficult, and time-consuming.

Moreover, scalp tattooing requires more effort and time because it requires artificially designing the hair roots naturally as if there were hair roots in the empty space on the scalp.

In addition, when tattooing the scalp using a roller-type needle, the time can be reduced, but since all disk needles provided on the roller have the same structure, the spacing of the holes drilled in the scalp appears very regularly. Therefore, it is difficult to give the hair a natural look like real hair roots.

Recently, as the hair loss population increases, interest in and procedures for scalp tattooing is increasing. Accordingly, providing an improved version of the conventional needle and tattoo device to increase the scalp tattoo effect can provide many advantages to the user.

This project is to provide a tattoo device and a needle roller for tattooing that can more quickly tattoo the scalp in an irregular pattern similar to actual hair roots.

Accordingly, when the user presses the push button 150 protruding to the outside of the housing 130, the cartridge 120 provided inside the housing 130 is pressurized and the solution contained in the cartridge 120 is transferred to the head portion 110. ) and can be supplied to the needle roller 200 through the passage 111.

In addition, the push button 150 is provided on the side of the housing 130, so the user can easily press the push button 150 while holding the housing 130 with his hand to operate it.

Therefore, it is possible to easily supply the solution directly to the needle roller 200 while tattooing the scalp without moving the needle roller 200 to the solution position.

The needle roller 200 is rotatably supported on the head portion 110 and rotates along the scalp in contact with the scalp. The needle roller 200 has a needle-shaped needle (see 215 in FIG. 4) with a sharp tip on its outer peripheral surface, and punctures the skin while rotating along the scalp. A pore-shaped tattoo can be formed on the scalp by injecting a solution into a hole drilled in the scalp by the needle roller 200 and dyeing the dye. The structure of the needle roller 200 will be described again later.

The head portion 110 rotatably supports the needle roller 200 and is coupled to the housing 130 via a connector 140 to connect the cartridge 120 and the needle roller 200.

The head portion 110 has a support portion 112 formed at the outer end to rotatably support the needle roller 200, and the other end forms a mounting portion 114 to be detachably coupled to the connector 140.

The support portion 112 and the mounting portion 114 of the head portion 110 may be formed integrally to form one body. As shown in FIG. 3, a passage 111 is formed inside the head portion 110 to communicate between the support portion 112 and the mounting portion 114 to transfer the solution.

The support portion 112 of the head portion 110 has a shape that opens toward both ends of the needle roller 200, and a coupling groove into which the rotation axis of the needle roller 200 (see 232 in FIG. 4) is inserted and rotatably coupled. (213) can be formed. The solution discharged from the support part 112 through the passage 111 may be supplied to the needle roller 200 coupled to the support part 112.

The mounting portion 114 of the head portion 110 has a cylindrical shape and is fastened to the connector 140. In this embodiment, the mounting portion 114 may be pressed into and coupled to the connector 140. The overall size of the head portion 110 or the shape of the mounting portion 114 of the support portion 112 may be modified in various ways.

The connector 140 connects the housing 130 and the head portion 110. The connector 140 may be provided in various types to match the shape or size of the head portion 110. Accordingly, the head portion 110 of various sizes and shapes can be coupled to the housing 130 via the connector 140.

The connector 140 has a cylindrical shape with both ends open, and may include a thread portion 142 screwed to the tip of the housing 130 and a socket portion 144 into which the head portion 110 is inserted. The socket portion 144 is formed with an inner diameter corresponding to the outer diameter of the mounting portion 114 of the head portion 110, so that the mounting portion 114 of the head portion 110 can be forcibly fitted and coupled to the socket portion 144. The connector 140 may be provided with a socket portion 144 of various sizes or shapes. Accordingly, it can be used for general purposes by combining various types of head parts with the housing.

In this embodiment, the connector 140 may be made of silicon or rubber.

A thread is formed on the outer peripheral surface of the thread portion 142 and the inner peripheral surface of the tip of the housing 130 to engage with each other. Accordingly, the thread portion 142 of the connector 140 can be installed in the housing 130 by screwing it.

In addition to the screw fastening structure, the mounting portion 114 of the head portion 110 and the housing 130 are formed with concavo-convex grooves and convex portions on the contact surfaces, so that the concave portions and convex portions can be engaged or pressed together. .

The housing 130 may be a cylindrical structure with both ends open and elongated. The housing 130 is made of a rigid material such as steel, and surrounds and protects the cartridge 120 provided therein. The diameter or length of the housing 130 may be modified in various ways.

The cartridge 120 forms a space inside which can accommodate a solution, and has a structure in which a neck 122 is formed to extend long at one end, and an outlet 124 for discharging the solution is formed at the end of the neck 122. there is. The cartridge 120 may be formed to have a diameter that allows insertion into the housing 130. The size of the cartridge 120 may be modified in various ways.

The cartridge 120 is pressed and deformed by an external force, thereby applying pressure to the inside. Accordingly, the solution contained therein is discharged through the outlet 124 formed in the neck 122.

The neck portion 122 of the cartridge 120 may be detachably coupled to the inner passage 111 of the head portion 110. Accordingly, the cartridge 120 can be removed and replaced from the head unit 110 when necessary. Therefore, after all the solution in the cartridge 110 has been used, the cartridge 110 can be separated from the head unit 110, injected with a new solution therein, and then re-installed on the head unit to be reused.

Alternatively, the cartridge 110 may be a disposable structure. Accordingly, after using the cartridge, it can be separated from the head, discarded, and replaced with a new cartridge.

In order to mount the cartridge 120, threads that mesh with each other are formed between the neck portion 122 of the cartridge 120 and the passage 111 of the head portion 110, and may have a structure in which they are screwed together and coupled to each other. For example, a male thread portion 116 communicating with the passage 111 is protruding from the mounting portion 114 of the head portion 110, and a female thread is formed on the inner peripheral surface of the neck portion 122 of the cartridge 120 to form a male thread portion ( 116) can be connected by screwing.

In addition to the above structure, the neck portion 122 of the cartridge 120 may have a structure in which the diameter becomes smaller as it approaches the outlet 124 and is press-fitted and coupled to the inside of the passage 111 of the head portion 110. Accordingly, the cartridge can be simply mounted on the head and used.

As the neck portion 122 of the cartridge 120 is connected to the head portion 110, the outlet 124 of the cartridge 120 communicates with the passage 111. Therefore, when pressure is applied by pressing the cartridge 120, the solution contained within the cartridge 120 is discharged through the outlet 124 and can be supplied to the needle roller 200 along the passage 111.

In this embodiment, the cartridge 120 may be formed of a material that has elasticity itself. Accordingly, when external force is removed from the cartridge 120, the push button 150 that presses the cartridge 120 can be returned to its original state. For example, the cartridge 120 may be made of rubber, silicone, or a resin material with an appropriate elastic recovery force capable of pushing the push button 150.

The cartridge 120 is pressed by the push button 150 installed on the housing 130 to discharge the solution.

The push button 150 is installed through the hole 132 formed on the side of the housing 130 and has a structure to press the cartridge 120 from the outside of the housing 130.

In this embodiment, two push buttons 150 may be arranged on the outer peripheral surface of the housing 130 at an angle of 180 degrees. Accordingly, push buttons 150 protrude on both sides of the housing 130, allowing the user to more comfortably hold the housing 130 by hand using the two push buttons 150. In addition, the amount of solution discharged from the cartridge 120 can be more precisely controlled by pressing the two push buttons 150 together or selectively pressing one button.

The structure of each push button 150 is the same, and the structure of one side push button 150 will be described below.

The push button 150 is formed integrally with the pressing part 152 and the pressing part 152 protruding to the outside of the housing 130, and has a shaft part 154 penetrating the hole 132 and an inner end of the shaft part 154. It may include a pressing portion 156 that contacts the cartridge 120 and presses the cartridge 120.

The pressing portion 152, the shaft portion 154, and the pressing portion 156 may be formed integrally to form one body.

The shaft portion 154 is formed to be approximately smaller than the diameter of the hole 132 and can smoothly flow in and out through the hole 132.

The shaft portion 154 may be divided into a plurality of ribs 153 having elastic force, and a hook 155 formed at the tip of the rib 153 to be caught in the hole 132. The hook 155 has a roughly triangular cross-sectional shape so that it can be easily inserted into the hole 132 to the outside. The outer tip of the hook 155 forms the pressing portion 156.

Accordingly, the ribs 153 of the shaft portion 154 are elastically gathered and the hook 155 is inserted through the hole 132, and when the shaft portion 154 is completely inserted into the hole 132, the ribs 153 are elastic. As it is restored, it opens outward and the hook 155 is caught in the hole 132 and fixed. Therefore, the push button 150 can be simply mounted in the hole 132 of the housing 130.

As the ribs 153 spread and the hook 155 is caught in the hole 132, the push button 150 does not easily fall out of the hole 132.

In this embodiment, the hole 132 may have a structure in which a stepped 134 is formed so that the pressing portion 152 is inserted. The step 134 is formed with a diameter relatively larger than the diameter of the hole 132 and may be formed with a diameter approximately larger than the size of the pressing portion 152.

Accordingly, the push button 150 can be pressed as deeply into the housing 130 as possible. That is, the pressing part 152 is further pressed by the depth of the step on the outer surface of the housing 130, so that the pressing part 156 can be moved further toward the center of the housing 130. Accordingly, the cartridge 120 is further pressed and deformed by the pressurizing portion 156, allowing a large amount of solution to be discharged.

In this way, the user simply presses the pressing portion 152 of the push button 150 protruding to the outside of the housing 130, thereby pressurizing the cartridge 120 provided inside the housing 130 and transferring the solution to the needle roller. It can be supplied as (200).

When the user presses the pressing part 152, the pressing part 156 connected to the shaft part 154 presses the cartridge 120 inside the housing 130 to apply pressure. The cartridge 120 is deformed by being pressed by the pressurizing portion 156, and the solution contained therein is discharged through the outlet 124.

Accordingly, the solution in the cartridge 120 is discharged into the passage 111 of the head portion 110 connected to the outlet 124, and is transported along the passage 111 to the needle coupled to the tip of the head portion 110. It is supplied to the roller 200. Accordingly, the user can continuously receive the solution from the cartridge 120 without having to separately apply the solution to the needle roller 200. The user can finely adjust the amount of solution discharged from the cartridge 120, that is, the amount of solution supplied to the needle roller 200, by adjusting the force with which the push button 150 is pressed.

In this embodiment, the push button 150 may be pushed by the elastic restoring force of the cartridge 120 and returned to its original state. When the external force on the push button 150 is removed, the cartridge 120 is deformed to its original state by its own elastic restoring force. In this process, since outside air flows into the cartridge 120 through the passage 111 and the outlet 124, the cartridge 120 can be easily returned to its original state.

Accordingly, the pressing portion 156 that was pressing the cartridge 120 is pushed outward by the cartridge 120 being restored to its original state. Accordingly, the push button 150 that was pressed inside the housing 130 may be pushed outward and returned to the state before being pressed.

In addition to the above structure, an elastic member for applying elastic force may be further installed between the push button and the housing.

Additionally, the tattoo device 100 of this embodiment may further include an auxiliary needle portion 160 that is detachably provided at the other end of the housing 130.

The auxiliary needle portion 160 may include a connector 140 coupled to the housing 130, and a head portion 110 coupled to the connector 140 and to which a needle roller 200 is coupled to the distal end. The connector 140 and the head portion 110 of the auxiliary needle portion 160 may have the same structure as the structure mentioned above.

By additionally providing the auxiliary needle unit 160, the needle roller 200 coupled to the housing 130 can be separated and replaced with the auxiliary needle unit 160, when necessary, to quickly perform the desired work.

In addition to the needle roller 200, the auxiliary needle unit 160 may be provided with a needle roller 200 or needle of a different structure. For example, the auxiliary needle unit 160 may have a structure including a single needle disk 164 in the shape of a disk.

The needle disk 164 has a disk-shaped structure with needles formed on the outer peripheral surface, and can be connected to the head portion 110 through the shaft member 162. The tip of the head portion 110 has a structure in which the shaft member 162 can be inserted and coupled. The head portion 110 of the auxiliary needle portion 160 also has a passage 111 formed therethrough, and the solution discharged through the passage 111 is supplied to the needle disk 164 through the shaft member 162. You can.

In this way, by additionally providing an auxiliary needle part 160 with a needle disk 164 of a different structure installed at the tip of the housing 130 in addition to the needle roller 200, various procedures can be performed by replacing the auxiliary needle part 160. You can quickly switch between tattoo tasks.

Meanwhile, Figures 4 and 5 show the structure of the needle roller 200 according to this embodiment.

Hereinafter, the structure of the needle roller 200 will be described with reference to FIGS. 4 and 5.

The needle roller 200 of this embodiment can be mounted on the tattoo device 100 of this embodiment and used for scalp tattooing.

The needle roller 200 of this embodiment includes a plurality of needle disks (210, 212, 214) with a central hole 211 formed at the center and needles 215 at the tip at intervals in the circumferential direction, and a central hole 211 at the center. A spacer 220 is formed and inserted between the needle disks 210, 212, 214 and the needle disks 210, 212, 214 to space the needle disks 210, 212, 214, and an axis passing through the needle disks 210, 212, 214 and the center hole 211 of the space ( 240), may include a pair of side members 230 that are respectively coupled to both ends of the shaft 240 and support the needle disks 210, 212, and 214 and the spacer 220.

This embodiment has a structure equipped with three needle disks (210, 212, 214). The needle roller 200 may have a structure including two or four or more needle disks in addition to the three needle disks 210, 212, and 214.

Hereinafter, the needle roller 200 of this embodiment will be described as an example of a structure including three needle disks 210, 212, and 214.

The needle disks 210, 212, and 214 and the spacer 220 may be alternately installed on one shaft 240 and rotatably installed.

The needle disks 210, 212, and 214 may have a disk shape with a central hole 211 formed in the center so that the shaft 240 can be inserted, and a plurality of needles 215 may be formed to protrude at intervals along the outer peripheral surface.

The spacer 220 is formed in a disk shape with a relatively smaller outer diameter than the outer diameter of the needles 215 formed on the needle disks 210, 212, and 214. Accordingly, the needles 215 formed on the needle disks 210, 212, and 214 may protrude further outward from the spacer 220 to puncture the scalp.

The needle disks 210, 212, 214 and the spacer 220 can be freely rotatably installed on the shaft 240. A pair of side members 230 supporting the needle disks 210, 212, and 214 and the spacer 220 and coupled to the shaft 240 are provided at both ends of the needle roller 200. Both ends of the shaft 240 may be coupled to the inner surface of each side member 230. On the outside of the side member 230, a rotation axis 232 is formed to form the rotation center axis of the needle roller 200 and is inserted into the coupling groove 113 formed in the support portion 112 of the head portion 110. Accordingly, the needle roller 200 is rotatably mounted on the head portion 110 via the rotation shaft 232.

The needle roller 200 may be rotated while being supported on the head portion 110 and may be in contact with the scalp. The needles 215 formed on the needle disks 210, 212, and 214 rotate along the scalp to puncture the scalp.

In the needle roller 200 of this embodiment, each needle disk 210, 212, and 214 may have a different structure. That is, at least one needle disk (210, 212, 214) may have a different structure compared to other needle disks in the number of needles 215, the spacing of needles 215, the length of needles 215, or the shape of needles 215. there is. Additionally, at least one needle disk 210, 212, and 214 may have a structure in which the spacing or length of each needle 215 is not constant.

For example, among the plurality of needle disks provided in the needle roller 200, at least neighboring needle disks may have structures with different numbers of needles 215. Neighboring needle disks may refer to needle disks facing each other with the spacer 220 in between.

Alternatively, among the plurality of needle disks provided in the needle roller 200, at least neighboring needle disks may have structures in which the needles 215 have different shapes.

Alternatively, at least one needle disk provided in the needle roller 200 may have a structure in which the spacing between needles 215 along the circumferential direction is not constant. Alternatively, at least one needle disk provided in the needle roller 200 may have a structure in which the length of the needle 215 along the circumferential direction is not constant.

Accordingly, the pattern of the tattoo formed by perforating the scalp with the needle roller 200 appears randomly and irregularly. Therefore, it is possible to tattoo the scalp by forming a pore pattern more naturally rather than artificially. Additionally, the color of the tattoo can be made more vivid.

Figure 5 shows an example of three needle disks 210, 212, and 214 provided on the needle roller 200 according to this embodiment.

As shown in FIG. 5, each of the needle disks 210, 212, and 214 is different from each other in the number of needles 215, the spacing, length, and shape of the needles 215. Figure 5(a) shows a needle disk 210 with single needle-shaped needles 215, and shows a structure with a total of 14 needles 215. Figure 5(b) shows a needle disk 212 with single needle-shaped needles 215, and shows a structure with a total of 16 needles 215. Figure 5(c) shows a needle disk 214 provided with a twin-needle type needle 215 in which the tip of the needle 215 is split into two.

The needle roller 200 of this embodiment is not limited to the needle disks 210, 212, and 214 shown in FIG. 5, and can be applied as long as the number, spacing, length, and shape of the needles of each needle disk are different.

The number or spacing of needles 215 may mean the total number of needles 215 formed on the needle disks 210, 212, and 214 or the distance between needles 215. As shown in FIG. 5, each of the three needle disks 210, 212, and 214 provided on the needle roller 200 has a different number or spacing of needles 215. In Figure 5, the needle disk 210 in (a) has 14 needles 215, the needle disk 212 in (b) has 16 needles 215, and the needle disk in (c) has 16 needles 215. (214) has a different structure having eight needles (215) in the form of twin needles.

In addition, the spacing between the needles 215 and the neighboring needles 215 along the circumferential direction of each needle disk 210, 212, and 214 may be irregular and not uniform overall. Not being constant may mean that the spacing between neighboring needles and the needles are not all the same. For example, as shown in the needle disk 212 of (b) in FIG. 5, the needle disk 212 may have different spacing D1 and D2 between neighboring needles 215. there is.

Even if the number of needles 215 of each needle disk 210, 212, and 214 is different, or the number of needles 215 is the same, the spacing between the needles 215 is not constant and is formed differently, so that the needle roller 200 is perforated. The pores of a scalp tattoo may be formed in an irregular pattern.

The length of the needle 215 may refer to the length from the circumferential surface of the disc-shaped needle disk to the top of the needle. Among the needle disks provided in the needle roller 200 of this embodiment, at least one needle disk 210, 212, and 214 may have a structure in which the length of the needle 215 along the circumferential direction is not constant. For example, as shown in the needle disk 210 of (a) in Figure 5, the needle disk 210 may be formed to have different lengths (L1) and lengths (L2) of neighboring needles 215. there is.

The needles 215 may be formed irregularly distributed along the circumferential direction of the needle disk with various lengths ranging from 0.10 mm to 0.30 mm. Accordingly, various pores with different perforation depths can be irregularly formed on the scalp, and the absorption rate of the solution into the scalp can be increased. Therefore, compared to tattooing the scalp by drilling the pores only to a certain depth, the color of the tattoo can be formed more vividly.

The shape of the needle 215 refers to the shape or structure of the needle 215 formed on the needle disks 210, 212, and 214. For example, the needle disks 210 and 212 of Figures 5 (a) and (b). As shown, the needle 215 may be in the form of a single needle with one attachment, or may be in the form of a twin needle with the attachment divided into two, like the needle disk 214 in (c) of FIG. 5. As the shapes of each needle disk (210, 212, and 214) are different, the pore shape of the scalp tattoo formed by the needle roller (200) can be naturally and irregularly formed.

In this way, the needle roller of this embodiment is provided with a plurality of needle disks, so that it is possible to pierce the scalp with a large number at once and tattoo the pores. Therefore, compared to the structure of drilling the scalp one by one and tattooing the pores, the time and effort required for scalp tattooing can be reduced.

In addition, the pores perforated on the scalp by each needle of the three needle disks provided in the needle roller and the spacing or density of the pores are not constant and are formed irregularly, making it possible to tattoo the scalp with a more natural pore shape.

Therefore, each time the needle roller rotates, pores are formed in a different pattern, making it possible to obtain a scalp tattoo effect like pendulum pores. In addition, the depth of perforation of the scalp by the needle varies, making it possible to obtain a tattoo with more vivid colors.

Although exemplary embodiments of the present invention have been shown and described as described above, various modifications and other embodiments will occur to those skilled in the art. These modifications and other embodiments are to be considered and included in the appended claims without departing from the true spirit and scope of the present invention.
