Description

Technical Field

[0001] The present invention relates to the technical field of tattooing, and in particular to a tattooing device. Background Art

[0002] A tattoo device is a tool used for tattooing. Most common tattoo devices are pen-shaped and have a gripping rod, a needle sheath, and a drive assembly for extending and retracting a needle within the needle sheath. The tattoo device is moved across the skin, creating a puncture in the skin with the needle. Tattoo pigment then seeps through the puncture to form a tattoo pattern with a specific color. However, existing tattoo devices often cause a large amount of pigment to overflow from the needle tip when the needle is retracted, resulting in significant waste and requiring frequent downtime for replenishment. Furthermore, when the needle penetrates the skin, pigment coated on the needle tip is scraped off by the edge of the puncture and is difficult to penetrate into the skin with the needle. The pigment can only penetrate the superficial layers of the skin through the puncture when the needle is removed from the skin, resulting in low coloring efficiency and poor results. Multiple reciprocating movements are required to achieve the desired tattoo effect, resulting in low tattoo efficiency. Summary of the Invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a tattoo device with small colorant waste, good coloring effect and high tattoo efficiency.

[0004] In order to achieve the above-mentioned object, the present invention provides a technical solution that a tattoo device extends in the vertical direction, and the tattoo device includes:

[0005] A hollow cylindrical gripping rod with a detachable end cap provided on the top of the gripping rod;

[0006] A needle sleeve detachably connected to the bottom of the gripping rod is an integrally molded injection molded part. The needle sleeve comprises, from top to bottom, a plug cover, a storage portion, and a needle nozzle. The storage portion is provided with a feeding port for replenishing colorant, and the needle nozzle gradually retracts downward.

[0007] The guide assembly, reset sleeve and needle assembly are arranged in the needle sleeve, and the guide assembly includes a plug cover inserted and squeezed at the upper opening of the plug cover, a push rod movably arranged in the center hole of the plug cover, an annular groove is provided on the outer wall of the plug cover, the upper end of the push rod protrudes upward from the top surface of the plug cover, and the lower end of the push rod is provided with an annular flange located below the plug cover; the reset sleeve is a thin-walled telescopic sleeve that is larger at the top and smaller at the bottom, the upper end of the reset sleeve is sleeved in the annular groove, and the lower end of the reset sleeve is sleeved on the bottom of the annular flange; the needle assembly is connected to the bottom of the push rod and is located below the reset sleeve, and the needle assembly includes a plurality of steel needles, the needle tails of these steel needles are connected to the needle body, and a color material cavity for accommodating color material is formed between the needle heads of these steel needles;

[0008] A drive assembly is disposed in the gripping rod and above the push rod, the drive assembly being used to drive the push rod to move up and down, so that the push rod can drive the needle assembly to retract or extend the needle mouth portion of the needle sleeve to perform a tattoo operation;

[0009] The inner wall of the needle mouth of the needle guard is provided with a plurality of recesses for accommodating colorant. The recesses are provided near the lower opening of the needle guard. When the needle assembly is retracted into the needle guard, the colorant in the recesses blocks the flow of the colorant near the inner wall of the needle mouth through a viscosity effect, thereby increasing the energy loss of the colorant during flow, reducing its fluidity, causing the colorant to accumulate at the needle mouth, and enhancing the capillary effect at the lower opening of the needle guard, thereby reducing the amount of colorant overflowing from the lower opening and reducing colorant waste.

[0010] The outer wall of the needle head of the steel needle is provided with a plurality of grooves for accommodating colorants. When the needle assembly extends out of the needle mouth and pierces the skin, the colorants in the grooves can follow the needle head into the deep layer of the skin and diffuse into the tissue fluid in the deep layer of the skin, dyeing the deep layer of the skin, thereby enhancing the coloring effect.

[0011] Preferably, the recesses are formed by impacting sandblasting abrasives.

[0012] Further preferably, the closer to the lower opening, the higher the density of the pits.

[0013] Preferably, the groove is formed by grinding with a grinding wheel.

[0014] Further preferably, the closer to the tip of the needle head, the lower the density of the grooves.

[0015] Further preferably, the angle between the extending direction of the groove and the horizontal plane is less than or equal to 15°.

[0016] Preferably, the driving assembly includes a static iron core, a coil, and a moving magnet. The longitudinal section of the static iron core is I-shaped. The coil is wound on the static iron core. The moving magnet is arranged below the static iron core so as to be movable up and down. The bottom of the moving magnet is in conflict with the upper end face of the push rod. When alternating current is passed through the coil, the magnetic pole at the bottom of the static iron core changes continuously, repelling or attracting the moving magnet, causing the moving magnet to move up and down, thereby driving the push rod to move up and down.

[0017] Further preferably, the longitudinal section of the moving magnet is T-shaped, a reset spring is sleeved on the lower part of the moving magnet, and both ends of the reset spring are respectively pressed against the mounting steps of the moving magnet and the inner wall of the holding rod.

[0018] Further preferably, the drive assembly further includes a frequency regulator, which is disposed above the static iron core and is used to adjust the frequency of the alternating current entering the coil.

[0019] Further preferably, the bottom of the moving magnet is threadedly connected to an adjustment sleeve for pressing against the upper end surface of the push rod. When the adjustment sleeve rotates relative to the moving magnet, the distance between it and the moving magnet can be changed, thereby adjusting the initial position of the push rod and the needle assembly.

[0020] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0021] 1. By providing a plurality of recesses for accommodating pigment on the inner wall of the needle mouth of the needle guard, and positioning the recesses close to the lower opening of the needle guard, when the needle assembly is retracted into the needle guard, the pigment in the recesses can be used to block the flow of pigment near the inner wall of the needle mouth, thereby increasing the energy loss of the pigment during flow, reducing its fluidity, causing the pigment to accumulate in the needle mouth, enhancing the capillary effect at the lower opening of the needle guard, reducing the amount of pigment overflowing from the lower opening, and reducing pigment waste.

[0022] 2. By setting a number of grooves for accommodating colorants on the outer wall of the steel needle head, when the needle assembly extends out of the needle mouth and pierces the skin, the colorant in the groove can follow the needle head into the deep layer of the skin and diffuse into the tissue fluid in the deep layer of the skin through the diffusion effect, dyeing the deep layer of the skin, thereby enhancing the coloring effect.

[0023] 3. Due to less waste of pigment, the frequency of pigment replenishment can be reduced. When tattooing, the pigment can be transferred to the skin through the pigment cavity, ensuring that there is enough pigment at the break to penetrate and dye the shallow layer of the skin. The pigment carried by the groove can also be diffused and dyed to the deep layer of the skin. This part of the pigment does not need to penetrate through the surface of the skin, and the shallow and deep layers of the skin can be dyed at the same time, with fast coloring speed, good coloring effect and high tattoo efficiency.

[0029] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0030] The up and down directions described in the present invention refer to Figure 1 The up and down directions in .

[0031] like Figures 1 to 4As shown, the tattoo device 1 provided by the present invention extends in the up-down direction and includes: a gripping rod 10, a needle sleeve 20, a guide assembly 30, a reset sleeve 40, a needle assembly 50, and a drive assembly 60. The gripping rod 10 is hollow cylindrical and has a detachable end cap 11 on its top; the needle sleeve 20 is detachably connected to the bottom of the gripping rod 10, and the guide assembly 30, the reset sleeve 40, and the needle assembly 50 are disposed in the needle sleeve 20. Specifically, the needle sleeve 20 is an integrally molded injection molded part, and the needle sleeve 20 includes a plug cover portion 21, a storage portion 22, and a needle nozzle portion 23 from top to bottom. The upper opening of the needle sleeve 20 is opened at the top of the plug cover portion 21, and the lower opening 24 of the needle sleeve 20 is set at the bottom of the needle mouth portion 23. The storage portion 22 is provided with a feeding port 221 for replenishing the colorant, and the needle mouth portion 23 is gradually retracted downward; the guide assembly 30 includes a plug cover 31 inserted and squeezed at the upper opening of the plug cover portion 21, and a push rod 32 that is movably inserted into the central hole 311 of the plug cover 31. The outer wall of the plug cover 31 is provided with an annular groove 312. The upper end of the push rod 32 protrudes upward from the top surface of the plug cover 31, and the lower end of the push rod 32 is provided with an annular flange located below the plug cover 31. 321; the reset sleeve 40 is a thin-walled telescopic sleeve with a larger upper portion and a smaller lower portion. The upper end of the reset sleeve 40 is sleeved in the annular groove 312, and the lower end of the reset sleeve 40 is sleeved in the bottom of the annular flange 321; the needle assembly 50 is connected to the bottom of the push rod 32 and is located below the reset sleeve 40. The needle assembly 50 includes a plurality of steel needles 51, the needle tails 511 of these steel needles 51 are welded, and the needle bodies 512 of these steel needles 51 are welded, and a colorant cavity 514 for accommodating colorant is formed between the needle heads 513 of these steel needles 51; the drive assembly 60 is arranged in the gripping rod 10 and is located Above the push rod 32, a drive assembly 60 is used to drive the push rod 32 to move up and down, so that the push rod 32 can drive the needle assembly 50 to retract or extend the needle mouth portion 23 of the needle sleeve 20 to perform the tattoo operation; the inner wall of the needle mouth portion 23 of the needle sleeve 20 is provided with a plurality of pits 231 for accommodating pigment, and the pits 231 are arranged near the lower opening 24 of the needle sleeve 20. The outer wall of the needle head 513 of the steel needle 51 is provided with a plurality of grooves 515 for accommodating pigment. The size of the pits 231 and the grooves 515 is determined by the size of the large particles in the pigment, and the diameter of these particles is generally between 20-200 μm.

[0032] The benefits of this setting are:

[0033] 1. When the needle assembly 50 is retracted into the needle guard 20, the pigment in the recess 231 can block the flow of pigment near the inner wall of the needle mouth 23 through the viscosity effect, increasing the energy loss of the pigment during flow, reducing its fluidity, causing the pigment to accumulate in the needle mouth 23, enhancing the capillary effect at the lower opening of the needle guard 20, reducing the amount of pigment overflowing from the lower opening 24, and reducing pigment waste.

[0034] 2. When the needle assembly 50 extends from the needle mouth 23 and penetrates the skin, the colorant in the groove 515 can follow the needle head 513 into the deep layer of the skin and diffuse into the tissue fluid in the deep layer of the skin, dyeing the deep layer of the skin, thereby enhancing the coloring effect.

[0035] 3. Since there is less waste of pigment, the frequency of pigment replenishment can be reduced. When tattooing, the pigment can be transferred to the skin through the pigment cavity 514, ensuring that there is enough pigment at the skin break to penetrate and dye the superficial layer of the skin. The pigment carried by the groove 515 can also be diffused and dyed to the deep layer of the skin. This part of the pigment does not need to penetrate through the surface layer of the skin, and the superficial and deep layers of the skin can be dyed at the same time, resulting in a fast coloring speed, good coloring effect, and high tattoo efficiency.

[0036] In this embodiment, the pits 231 are formed by impacting abrasives in sandblasting. The closer to the lower opening 24, the higher the density of the pits. This arrangement can adapt to the shape of the needle sleeve 20, using the sandblasting operation that flows in from the feeding port 221 and out from the lower opening 24 of the needle mouth 23 to directly impact the pits 231, and can also improve the blocking effect on the colorant at the lower opening 24. The grooves 515 are formed by grinding with a grinding wheel. The closer to the tip of the needle head 513, the lower the density of the grooves 515. The angle between the extension direction of the grooves 515 and the horizontal plane is less than or equal to 15°. This arrangement can facilitate the grinding operation of the grinding wheel and make it difficult for the colorant in the grooves 515 to flow out under the action of its own weight.

[0037] In this embodiment, the driving assembly 60 includes a static iron core 61, a coil 62, and a moving magnet 63. The longitudinal section of the static iron core 61 is I-shaped, the coil 62 is wound on the static iron core 61, and the moving magnet 63 is arranged below the static iron core 61 so as to be movable up and down. The bottom of the moving magnet 63 is in conflict with the upper end surface of the push rod 32. When alternating current is passed through the coil, the magnetic poles at the bottom of the static iron core 61 continuously change, repelling or attracting the moving magnet 63, causing the moving magnet 63 to move up and down, thereby driving the push rod 32 to move up and down, causing the needle assembly 50 to extend or retract the needle mouth 23 to achieve the tattoo operation.

[0038] The advantage of this setting is that there is no need to change the direction of power transmission, the power transmission efficiency is higher, the structure of the drive component is simpler, the stability during use is better, and the drive component can be better miniaturized and cylindrical, so that it can be conveniently set in the grip rod.

[0039] In this embodiment, the longitudinal section of the moving magnet 63 is T-shaped, and a return spring 64 is sleeved on the lower part of the moving magnet 63. The two ends of the return spring 64 are respectively pressed against the mounting steps 12 of the moving magnet 63 and the inner wall of the holding rod 10.

[0040] Preferably, the drive assembly 60 further includes a frequency modulator 65 , which is disposed above the static iron core 61 and is used to adjust the frequency of the alternating current entering the coil 62 , thereby changing the frequency at which the needle assembly 50 extends or retracts the needle mouth portion 23 .

[0041] In order to conveniently adjust the length of the needle assembly 50 extending out of the needle mouth 23, the bottom of the moving magnet 63 is threadedly connected to an adjusting sleeve 631 for pressing against the upper end surface of the push rod 32. When the adjusting sleeve 631 rotates relative to the moving magnet 63, the distance between the adjusting sleeve 631 and the moving magnet 63 can be changed, thereby adjusting the initial position of the push rod 32 and the needle assembly 50. In order to achieve a locking effect, the bottom of the moving magnet 63 is also threadedly connected to a locking sleeve 632. The locking sleeve 632 is located above the adjusting sleeve 631, which is convenient for adjusting the sleeve 63. 1. Rotation of the locking sleeve 632 relative to the moving magnet 63. In this embodiment, adjustment holes 633 are evenly distributed on the bottom outer wall of the moving magnet 63, the outer wall of the adjustment sleeve 631, and the outer wall of the locking sleeve 632. An adjustment window 13 is opened at the gripping rod 10 corresponding to the adjustment holes 633. When adjusting, the three adjustment rods are extended from the adjustment window 13 and inserted into the adjustment holes 633 located on the moving magnet 63, the adjustment sleeve 631, and the locking sleeve 632. The adjustment sleeve 631 and the locking sleeve 632 are rotated relative to the moving magnet 63.
