Description

Technical Field

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

[0002] A tattoo device is a specialized device that creates specific colors and patterns on the skin by puncturing the skin to allow pigment to penetrate. The needle sleeve structure is the core component of the tattoo device, typically comprising a housing with a needle channel, a needle retractably disposed within the needle channel, a pigment chamber for storing pigment and communicating with the needle channel, and a telescopic positioning assembly for retracting and positioning the needle. To facilitate the outflow of pigment, the inner wall of the housing, especially the inner wall of the needle channel, is mostly smooth. When the needle is retracted, some pigment will flow out along the needle channel under its own weight, resulting in waste. 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 needle sleeve structure that can reduce the waste of pigment.

[0004] In order to achieve the above-mentioned object, the present invention provides a technical solution, which is a tattoo device needle sleeve structure, comprising:

[0005] A tubular shell, the shell comprising an end cover portion, a storage portion, and a needle mouth portion from top to bottom, the storage portion being provided with a feed hole, and the needle mouth portion being gradually retracted from top to bottom;

[0006] A plug cover, wherein the middle portion of the plug cover is inserted into the upper opening of the end cover and squeezed tightly, a through hole extending downward is provided in the center of the top surface of the plug cover, and an annular groove is provided on the outer wall of the lower end portion of the plug cover;

[0007] a push rod, the push rod being movably disposed in the through hole, the upper end of the push rod protruding upward from the plug cover, and the outer wall of the lower end of the push rod being provided with an annular flange;

[0008] A reset sleeve, which is a thin-walled telescopic sleeve with a larger upper portion and a smaller lower portion, wherein the upper end of the reset sleeve is clamped in the annular groove, and the lower end of the reset sleeve is sleeved on the bottom of the annular flange;

[0009] A needle, the needle being connected to the bottom of the push rod and being able to drive the needle to retract into the lower opening of the needle mouth or to extend from the lower opening when the push rod moves up and down;

[0010] The inner wall of the needle mouth is a frosted surface with several small pits. When the pigment flows through the frosted surface, a part of the pigment enters the pits, and the flow of the pigment close to the frosted surface is blocked by the viscosity effect, 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 mouth, reducing the amount of pigment flowing out of the lower opening, and reducing the waste of the pigment.

[0011] Preferably, the pit is an impact pit generated when abrasive hits the inner wall of the needle mouth during sandblasting.

[0012] Preferably, the density of the pits in a certain area on the frosted surface is negatively correlated with the distance between the area and the lower opening.

[0013] Preferably, the needle head is composed of a plurality of steel needles that are fully welded together at the needle body and the needle handle, and a material cavity for accommodating the colorant is formed between the needle tips of the plurality of steel needles.

[0014] Preferably, the cross section of the through hole is polygonal, and the cross section of the middle portion of the push rod matches the through hole to prevent the push rod from rotating around its own axis relative to the through hole when moving up and down.

[0015] Further preferably, the upper opening of the through hole is inwardly contracted and matches the cross section of the upper end portion of the push rod, so as to prevent the push rod from detaching upward from the plug cover.

[0016] Preferably, the middle outer wall of the plug cover is provided with a longitudinal ridge protruding outward, and the end cover is provided with a positioning groove matching the longitudinal ridge. When the longitudinal ridge is inserted into the positioning groove, the relative angle between the plug cover and the end cover in the circumferential direction remains locked.

[0017] Preferably, a metal plug-in column for connecting with the needle is inserted in the center of the bottom surface of the push rod, and the outer wall of the lower end of the plug-in column is welded to the upper end of the needle.

[0018] Further preferably, the plug post, the push rod, the end cover portion, and the storage portion are coaxially arranged, and the needle mouth portion is eccentrically arranged relative to the end cover portion and the storage portion to match the retraction and extension of the needle.

[0019] Further preferably, the housing is an integrally formed injection molded part.

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

[0021] By making the inner wall of the needle mouth a frosted surface with several small pits, when the pigment flows through the frosted surface, a part of the pigment can enter the pits, thereby utilizing the viscosity effect to block the flow of the pigment close to the frosted surface, increasing the energy loss of the pigment during flow, reducing its fluidity, causing most of the pigment to accumulate in the needle mouth, enhancing the capillary effect at the lower opening of the needle mouth, reducing the amount of pigment flowing out of the lower opening, and thus reducing pigment waste.

[0026] 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.

[0027] The up and down directions described in the present invention refer to Figure 1 The up and down directions in .

[0028] like Figure 1 and Figure 2As shown, the tattoo device needle sleeve structure provided by the present invention includes: a shell 10, a plug cover 20, a push rod 30, a reset sleeve 40, and a needle 50. The shell 10 is tubular and is an integrally formed injection molded part. The shell 10 is composed of an end cover 11, a storage part 12, and a needle mouth 13 from top to bottom. The end cover 11 is used to connect to the plug cover 20. The storage part 12 is used to store a certain amount of tattoo colorant. The storage part 12 is provided with a feed hole 121 for replenishing the colorant. The needle mouth 13 gradually retracts from top to bottom. The middle part of the plug cover 20 is inserted into the upper opening of the end cover 11 and squeezed tightly. The center of the top surface of the plug cover 20 is provided with a through hole 21 extending downward. The outer wall of the lower end of the plug cover 20 is provided with an annular groove 22; the push rod 30 is movably arranged in the through hole 21, the upper end of the push rod 30 protrudes upward from the plug cover 20, and the outer wall of the lower end of the push rod 30 is provided with an annular flange 31; 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 clamped in the annular groove 22, and the lower end of the reset sleeve 40 is sleeved on the bottom of the annular flange 31; the needle 50 is connected to the bottom of the push rod 30 and is located below the reset sleeve 40. When the push rod 30 moves up and down, it can drive the needle 50 to retract the lower opening 131 of the needle mouth part 13 or extend downward from the lower opening 131 to realize the tattoo function.

[0029] In this embodiment, the inner wall of the needle mouth portion 13 is a frosted surface 133 having a plurality of small dimples 132. This arrangement has the advantage that, when the pigment flows downward from the storage portion 12 and passes through the frosted surface 133, a portion of the pigment can enter the dimples 132, thereby utilizing the viscosity effect to block the flow of the pigment near the frosted surface 132, thereby increasing the energy loss of the pigment when flowing within the needle mouth portion 13, reducing its fluidity, causing most of the pigment to accumulate in the needle mouth portion 13, and enhancing the capillary effect at the lower opening 131 of the needle mouth portion 13, thereby reducing the amount of pigment flowing out of the lower opening 131, thereby reducing pigment waste and improving pigment utilization. Compared with a tattoo device needle sleeve structure without a frosted surface 132, the use time after each addition of pigment can be extended by 10%-30%.

[0030] In order to facilitate the processing of the frosted surface 133 and improve the uniformity of the distribution of the pits 132, in this embodiment, the pits 132 are impact pits produced by the abrasive hitting the inner wall of the needle nozzle 13 during sandblasting. During sandblasting, the abrasive flows in from the feed hole and flows out from the lower opening 131 of the needle nozzle 13. Since the needle nozzle 13 gradually shrinks from top to bottom, its inner diameter gradually decreases. The closer to the lower opening 131, the higher the impact frequency of the abrasive, the higher the density of the pits, and the more obvious the blocking effect on the colorant.

[0031] During use, since most of the colorant accumulates in the needle mouth 13, although it can soak into the needle 50, it is difficult to move downward with the needle 50. In order to ensure that the needle 50 can carry enough colorant to extend out during use and avoid the phenomenon of light color or color interruption caused by insufficient amount of colorant, in this embodiment, the needle 50 is composed of a plurality of steel needles 51 fully welded together at the needle body and needle handle, and a material cavity 521 for accommodating colorant is formed between the needle tips 52 of the plurality of steel needles 51. When the needle 50 moves downward and extends out of the lower opening 131, the colorant in the material cavity 521 can be forced to move with it. The arrangement of the plurality of steel needles 51 depends on actual needs, and the cross-sectional shape of the needle mouth 13 matches the needle 50.

[0032] In order to enhance the stability of the push rod 30 during its up and down reciprocating motion, in this embodiment, the cross-sectional shape of the through hole 21 is rectangular, and the cross-sectional shape of the middle part of the push rod 30 is also rectangular, and its size matches the cross-sectional shape of the through hole 21 to avoid the push rod 30 from shaking relative to the through hole 21 or rotating around its own axis when moving up and down. Furthermore, the upper orifice of the through hole 21 is retracted and matches the cross-sectional shape of the upper end of the push rod 30 to prevent the push rod 30 from upwardly separating from the plug cover 20. The advantage of such a setting is that the plug cover 20, the push rod 30, and the reset sleeve 40 can be connected into a whole to avoid the scattering of small components. After the needle 50 is connected to the bottom of the push rod 30, it can be inserted into the housing 10 together to complete the assembly, which is convenient to operate and efficient. It should be noted that the above-mentioned section is a cross section.

[0033] In this embodiment, the middle outer wall of the plug cover 20 is provided with a longitudinal ridge 23 protruding outward, and the end cover portion 11 is provided with a positioning groove 111 matching the longitudinal ridge 23. When the longitudinal ridge 23 is inserted into the positioning groove 111, the relative angle between the plug cover 20 and the end cover portion 11 in the circumferential direction remains locked.

[0034] To facilitate the connection between the needle 50 and the push rod 30, in this embodiment, a metal plug-in column 32 for connecting the needle 50 is inserted in the center of the bottom surface of the push rod 30, and the outer wall of the lower end of the plug-in column 32 is welded to the upper end of the needle 50. The plug-in column 32, the push rod 30, the end cover portion 11, and the storage portion 12 are coaxially arranged, and the needle mouth portion 13 is eccentrically arranged relative to the end cover portion 11 and the storage portion 12 to match the retraction and extension of the needle 50.

[0035] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
