Description

Technical Field

[0001] The invention relates to introducing a medium into skin, and in particular to a needle used for an electric eyebrow tattooing instrument. Background Art

[0002] The existing roller needle uses the spikes on the rolling disc to pierce the skin. Since the trajectory of the spikes on the disc teeth piercing the skin is a dotted line when rolling, the needle hole after rolling has only one round trip puncture. If it rolls back and forth again, it is difficult to restore to the original trajectory, resulting in the inability to achieve the function of multiple injections of colorant into the same needle hole position. In addition, the spikes on the disc are difficult to process and cause greater damage to the skin. The rolling gap is fixed and unchanged, and the effect of continuous lines cannot be formed.

[0003] At present, the wheel blade is directly sharpened, and in the production process, the wheel blade tip is not polished, resulting in burrs on the metal during cutting that damage the skin. If the wheel blade tip is polished in batches, the tip cannot rotate, resulting in the inability to polish 360 degrees. Chemical corrosion will cause the tip to become blunt, so the polishing cost is particularly high. In view of the problem that the tip on the wheel blade cannot be polished and polishing is difficult, and not polishing will cause great damage to the skin, the disc is generally cut by laser, punch, and wire cutting. The needle burrs on the disc processed by this method cannot be polished and polishing is difficult and the cost is very high. The tip of the unpolished disc is flat and non-circular, and the surface burrs cause great damage to the skin, which is not practical for skin tattooing. Summary of the invention

[0004] The present invention overcomes the shortcomings of the prior art and provides a needle for an electric eyebrow tattooing instrument, which can not only realize the function of multiple injections of colorant at the same needle hole position, but also form the effect of continuous lines.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a needle for an electric eyebrow tattoo instrument, comprising a main body and a needle, the main body is connected to the outer shell of the electric eyebrow tattoo instrument, the needle is driven to reciprocate by a power structure arranged in the inner cavity of the electric eyebrow tattoo instrument, and also includes a fixed frame and a wheel, the fixed frame is arranged at one end of the main body away from the outer shell of the electric eyebrow tattoo instrument, the wheel is movably arranged on the fixed frame, the wheel can rotate around the connection between it and the fixed frame, the needle is arranged close to the outer side of the wheel, the outer edge of the wheel is used to control the insertion depth of the needle, the needle tail of the needle penetrates the inner cavity of the fixed frame and the main body and is connected to the power structure of the inner cavity of the electric eyebrow tattoo instrument, and the number of the needle is at least one.

[0020] like Figure 1 to Figure 6 As shown, the present invention is a needle for an electric eyebrow tattoo instrument, comprising a main body 1 and a needle 2, wherein the main body 1 is connected to the housing of the electric eyebrow tattoo instrument, and the needle 2 is driven to reciprocate by a power structure arranged in the inner cavity of the electric eyebrow tattoo instrument, and the power structure pushes the needle 2 downward through the needle rod to perform a piercing action, and a thrust spring is arranged between the needle rod and the needle 2, and the needle 2 is pushed upward to reset and detach from the human skin by the thrust spring. The present invention also includes a fixing frame 3 and a wheel 4, wherein the fixing frame 3 is arranged at one end of the main body 1 away from the housing of the electric eyebrow tattoo instrument, and the wheel 4 moves It is arranged on the fixing frame 3, and the wheel 4 can rotate around the connection between it and the fixing frame 3. The needle 2 is arranged closely to the outside of the wheel 4, and the outer edge of the wheel 4 is used to control the insertion depth of the needle 2, wherein the part of the needle 2 extending out of the outer edge of the wheel 4 is adjustable in length, and the outer edge of the wheel 4 is used to prevent the needle 2 from piercing too deeply, and the wheel 4 presses an indentation on the human skin, and the needle 2 can spread color along the indentation, and the needle tail of the needle 2 passes through the inner cavity of the fixing frame 3 and the main body 1 and is connected to the power structure of the inner cavity of the electric eyebrow tattoo instrument, and the number of the needle 2 is at least one.

[0021] The needle tip is controlled to move in a gentle curve on the rolling skin, which is used for hairline tattooing. As it is difficult to draw a smooth arc trajectory with the hands, the disc rolls when the needle moves up and down, so that the pigment attached to the disc is released evenly. At the same time, the disc helps to control the depth. The exposed part of the needle tip attached to the skin is the insertion depth. The disc not only prevents the needle from being inserted too deep, but also controls the density of repeated punctures on the skin by controlling the rolling speed.

[0022] The outer edge of the wheel 4 is provided with a plurality of protrusions and / or notches. The protrusions provided on the disc can press marks on the skin for positioning, and the notches provided on the disc are used to rotate to the notches when rolling on the skin so that the needle tip is exposed to work, so that the needle can tattoo a fixed shape effect according to the length and depth of the notch. When the needle tip does not reach the notch, the needle tip is located on the inner side of the outer edge of the disc to prevent the needle tip from piercing the skin. When the disc is rolled, the notch of the disc is exposed and tattooing is carried out.

[0023] A positioning guide portion is provided on a partial or entire outer wheel rim of the wheel piece 4. The positioning guide portion is in a gradually changing arc shape, or in a wavy shape, or is a projection and / or notch arranged at intervals.

[0024] When the positioning guide part of the wheel 4 is a notch set at intervals, as the wheel 4 rotates, the needle tip can penetrate the skin only when it reaches the notch position. As the wheel 4 slowly rolls, the needle tip is always pressed in the groove. During rolling, each point at the corresponding position of the notch can be pierced multiple times, so that opposite, full and uniform color points remain on the skin. It is used for men's scalp hair loss, and visually forms a hair column.

[0025] The wheel piece 4 is fixed on the fixing frame 3 via a fixing piece 5 . A fixing shaft is normally arranged at one end of the fixing piece 5 , and the wheel piece 4 is matched and sleeved on the fixing shaft.

[0026] Two wheels 4 are arranged on the fixed shaft of the fixing member 5, and the two wheels 4 are arranged close to each other, and the needle 2 is located between the two wheels 4. The gap between the two wheels 4 is used to fill the colorant. The outer edges of the two wheels 4 can be made the same or different according to actual needs.

[0027] The side of the fixing frame 3 opposite to the fixing member 5 is provided with an arc groove, the fixing shaft of the fixing member 5 is matched and inserted into the arc groove, and the fixing shaft can move up along the arc groove when the wheel 4 rotates to broadcast the color, and an elastic rope is provided between the fixing shaft and the lower part of the fixing frame 3, and the elastic rope is used to pull the wheel 4 to the reset position of the arc groove after the color broadcasting is completed. When rolling on the skin, the wheel 4 moves up with the fixing shaft, and the needle tip is exposed to work, so that the needle can tattoo a fixed shape effect according to the direction of the outer edge of the wheel 4. The elastic rope is used for the wheel 4 to move down and return to its position. When not in operation, the needle tip is on the inner side of the disc to prevent the needle tip from piercing the skin. When the disc is rolled, the needle tip is exposed, and tattooing is in progress. By setting a notch on the outer edge of the wheel 4, the notch gradually disappears when the wheel 4 rotates to a certain angle, so that the shape of the tattoo on the skin is like the effect of a real eyebrow, which can ensure that each line is consistent and uniform.

[0028] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
