Detailed Description

The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The gist of the present invention will be further explained below with reference to the accompanying drawings and examples.

Example 1:

in order to obtain efficient and accurate coloring on skin, particularly when quick and accurate prick or line marking coloring is needed, the conventional tattooing device generally uses a single sharpened metal needle wire as an operation end, then welds the single needle wire to a needle handle, and fixes the single needle wire to an electric tattooing pen holder through a fixed end on the needle handle to form a single needle device; or marking and coloring, namely drawing and scratching the skin to carry pigment after the skin is broken at a single point.

The single needle device of the existing tattooing tool is that under the condition that an electric tattooing pen is started (namely, a power source is started), an operator observes a smear formed by a needle point moving at a high speed through naked eyes, the length of the smear protruding out of a needle protecting cap is observed by eyes, and then the thread pitch of the tattooing pen is adjusted manually, so that the length of a needle is adjusted; the length preset in the movement can also generate certain looseness and change along with mechanical vibration, so that the needle discharge is unstable, and the coloring and safety problems are easily generated during the operation, namely, when the needle point moves in a reciprocating manner in the radial direction in the needle protection cap at a high speed, the needle point is easy to penetrate deeply or shake left and right, so that the coloring material is colored to the outside of a target coloring area.

The inaccurate length of the needle can lead to the following problems: 1. the color materials are diffused to the outside of the target coloring area under the skin when the tattooing is too deep, so that the color materials can not be completely metabolized for years, namely, the so-called 'faint' accident in the tattooing industry; 2. the needle point is easy to bend, skin damage is increased, the coloring is slow, the operation is long, the repair period is prolonged, and the infection rate and the color retention rate are increased; 3. when the single needle moves in a high-speed radial reciprocating manner, the left and right shaking can occur, so that the coloring is not accurate, the pattern of the embroidered work is run, and the customer complaint is further caused.

The following describes the deficiencies of the conventional tattooing tool (single-needle device) with reference to fig. 1-6:

as shown in fig. 1, a single needle device 1000 of a conventional tattooing tool includes a single metal needle 1001 with one end sharpened, a needle protection cap 1002, and an electric tattooing pen holder 1003; as shown in fig. 2, the needle point portion, i.e., the portion of the sharpened end of the single wire 1001 protruding from the needle protection cap 1002 is the needle withdrawing length of the wire 1001, and the needle withdrawing length is recorded as L1001.

As shown in fig. 3, the skin section is marked as h, the subcutaneous blood vessel is marked as g, when using the single needle device 1000 of the existing tattooing tool, the operator holds the electric tattooing pen shaft 1003, when stabbing skin along the arrow a direction for coloring, the needle points are stabbed to the subcutaneous positions with different depths as the points c, d and e shown in fig. 3, which easily pierces the blood vessel network reaching the subcutaneous deeper part, thus easily causing the 'faint' accident.

As shown in fig. 4, when the operator holds the electric tattooing pen shaft 1003 and repeatedly marks and colors along the direction of arrow B, the needle tip penetrates deeper under the skin, and bends under the resistance of the skin to form a barb S.

As shown in fig. 5, after the electric tattooing pen shaft 1003 is started, i.e., when the power source is started, the single needle wire 1001 with one sharpened end reciprocates axially along the needle protection cap 1002 of the conventional single needle device 1000, and due to the lack of a radial limiting device, the single needle wire 1001 may swing left and right outside the needle protection cap 1002 as shown by an arrow J, which affects the exact position of coloring. As shown in fig. 6, the single wire 1001 may swing left and right in the needle protection cap 1002 as indicated by arrow T, and hit the inner wall of the needle protection cap 1002 to damage the needle tip.

Due to the characteristics of the structure and the metal material of the single-needle device of the existing tattooing tool, the single-needle device is easy to accidentally injure operators in the process of disassembling after use, is not easy to damage, is easier to accidentally injure others in the abandoning process, generates contact pollution, and is even repeatedly used, and generates blood disease propagation risk.

Scientific data shows that the average thickness of the epidermis of the face of a human is 0.2-1.0mm, the average thickness of the epidermis of the eyebrow is 0.5mm, the average thickness of the epidermis of the eyelid is 0.33mm, and the thickness of a piece of conventional 80g A4 paper is 0.11mm, namely the thickness of the thinner epidermis of the face of the human is about the thickness of 2-3 pieces of conventional A4 paper. Penetration through such thicknesses by existing single needle devices is difficult to control based on subjective experience. The inventor analyzes a large number of cases and finds that the 'faint' accidents in the tattooing industry occur frequently, namely, the single needle device of the existing tattooing tool is lack of the pricking depth limitation, and the operator generates larger personal errors only by subjective judgment. Therefore, the depth of the tattoo should be controlled according to the thickness of the epidermis layer at different operation sites, so as to reduce bleeding rate and prevent the occurrence of 'halation'.

According to industrial data accumulation and experimental analysis, the average color retention time of 0.05-1.0mm of eyebrow skin penetration of a human is 3 months to 10 years, the color retention time is longer the deeper the eyebrow penetration is, the penetration depth is more than 1.0mm, the average color retention period is more than 10 years, the mainstream requirement of the eyebrow tattooing market at present is semipermanent tattooing, the semipermanent tattooing refers to the color retention period of 1-2 years, and the skin penetration depth is controlled within the range of 0.3-0.6mm, namely the thickness of about 2-4 conventional 80gA4 paper.

In order to verify the relationship between the penetration depth and the color retention period of a single-needle device in the existing tattooing tool, the inventor carried out the following verification experiment:

the common model (namely the single needle device with the needle thread diameter of 0.30mm and the needle point length of 3 mm) in the single needle device of the existing tattooing tool is selected to carry out the prick test on the simulated human silica gel skin with the same specification, the average height of the needle point leaving the silica gel skin is 5mm, the average speed is 2 times per second, the average prick depth of 0.7mm needs about 0.06 kg-gram-force, the average prick depth of 0.3mm needs about 0.04 kg-gram-force, namely, the error of 0.4mm can occur when the difference between the penetration depths of 0.02 kg-f is 0.02 kg-f, which is equivalent to the difference between the weights of about 4-5 conventional A4 papers, the precision is hard to control subjectively by the manual experience, taking the eyebrow part as an example, the eyebrow part can be punctured to a depth of 0.3-0.6mm for a period of 1-2 years, and the eyebrow part can be punctured too deeply to cause an overlong eyebrow period only by a force error of 0.02 kgf, which is not in line with the mainstream requirement of eyebrow tattooing market for 1-2 years and is easy to cause customer complaints.

From the above, the penetration depth of the single needle device in the existing tattooing tool cannot be precisely controlled, so that the 'halation' accident is easily caused, the penetration depth is closely related to the color retention period of the pigment, and the tattooing effect is influenced by the inconsistent penetration depth and uncontrollable depth.

In order to overcome the defects of the existing tattooing tool, the utility model aims to provide the efficiently and accurately colored tattooing needle which can accurately limit the depth of penetration in advance. Compared with the prior art, the embroidery needle provided by the utility model at least has one or more of the following beneficial effects: 1. the depth of penetration and the left-right swing are limited in both axial and radial directions, so that the coloring accuracy is improved; 2. the overlong needle withdrawing can be reduced, the needle tip bending caused by too deep puncture is avoided, the skin injury is reduced, and the effective coloring rate is increased, so that the tattooing efficiency and the excellent rate of the works are improved; 3. meanwhile, the design that the tattooing tool is easy to damage after being used is added, so that the repeated use and the pollution abandoning are prevented, and the sanitary and safety risk is further reduced.

The detailed structure of the embroidery needle of the present invention will be described in detail with reference to the accompanying drawings:

referring to fig. 7(a), the embroidery needle of the present invention includes an embroidery protrusion 141, a guide body 110, a sleeve 150, and a stopper 160.

One side of the substrate 1411 is fixed to the first end 1111 of the guide pillar 111 (the substrate may be fixed to the first end), the second end 1112 of the guide pillar 111 is fixedly connected or detachably connected to a connecting rod 112, and the connecting rod 112 may be a column or other shape, and is mainly used for connecting the guide pillar 111 and a driving member.

In one embodiment, the shape of the flow guiding column 111 of the present invention may be any shape, and it only needs to satisfy any one of the following conditions:

condition 1: the shape and size of the first end face 1111 is the same as the shape and size of the second end face 1112;

condition 2: the shape of the first end face 1111 is the same as the shape of the second end face 1112, and the size of the first end face 1111 is smaller than the size of the second end face 1112;

condition 3: the shape of the first end surface 1111 is different from the shape of the second end surface 1112, and the size of the first end surface 1111 is smaller than the size of the second end surface 1112.

It can be seen from the above 3 conditions that the most basic feature of the flow conductor 110 is a cylindrical body, which can meet the flow guiding and guiding requirements in a vertical state, and the shape is arbitrary and can be designed and used according to the needs of users, and the shape mainly shown in the drawings is a cylindrical body and a cone-like body, which only illustrates the structure of the flow conductor and cannot be understood as a limitation on the shape of the flow conductor.

In one embodiment, the axial length of the guide post 111 of the present invention is greater than the length of the long side or the diameter of the cross-section of the first end surface 1111 of the guide post 111. That is, the flow guiding column 111 of the present invention is preferably an elongated column structure.

In one embodiment, the axial length of the guide post 111 is at least 2 times the length or diametric length of the shortest side of the first end face 1111 of the guide post 111, and the axial length of the guide post 111 is greater than the length or diametric length of the longest side of the first end face 1111. Satisfying the length-diameter ratio further specifies the shape proportion of the flow conductor 110, and the elongated flow conductor 110 in a vertical state has good flow guiding and liquid storage effects.

Example 8:

in the process of tattooing, tattooing ink 300 (or called dye) needs to be guided into the skin superficial layer through a tattooing tool, the existing tattooing tool absorbs a small amount of ink 300 after soaking the ink 300 each time, and in the high-frequency needling process, the ink amount on the tattooing tool cannot reach the ink amount in the stage needling process, so that the needle-free rate of tattooing needling is high. In order to improve the above disadvantages of the existing tattooing tool, the tattooing tool provided by the present invention is an improvement of the fluid guide 110 to satisfy the ink absorption amount during the tattooing process. The structure of current carrier 110 according to the present invention is specifically described as follows:

referring to fig. 23(a), the flow guide column 111 of the present invention is provided with a capillary liquid storage unit 120, the capillary liquid storage unit 120 can temporarily store ink 300, the flow guide body 110 is soaked in an ink bottle, the capillary liquid storage unit 120 on the flow guide body 110 adsorbs the ink and temporarily stores the adsorbed ink, the liquid stored in the capillary liquid storage unit 120 (under the action of gravity or other forces) is guided to the acupuncture part 140, the needle tooth 1412 punctures the skin surface, and the liquid is guided to the skin surface along with the needle tooth 1412. When the flow conductor 110 with the needle tooth 1412 of the acupuncture part 140 pricks the skin, the ink 300 stored in the capillary liquid storage unit 120 is gradually guided to the tip of the needle tooth 1412, and the utility model realizes the gradual ink delivery of the flow conductor 110 through the capillary liquid storage unit 120, ensures the continuous ink supply and reduces the empty needle rate.

As can be seen from the above, the tattooing needle is required to be transdermal during the tattooing process, and thus, the tattooing needle that has been used needs to be destroyed to prevent the transmission of pathogenic microorganisms after the secondary use, which has been considered in the present invention. Therefore, as shown in fig. 14, the needle teeth 1412 of the embroidery needle can be destroyed, and the needle-punching part of the embroidery needle can be destroyed directly, so that the remaining flow guiding column 111 can be further reused.

With continued reference to fig. 19(a), in one embodiment, the flow guiding column 111 of the present invention may be provided with a plurality of channels 115, where the channels 115 are disposed on an outer wall of the flow guiding body 110 and/or inside the flow guiding body 110 along an axial direction of the flow guiding body 110, and the plurality of channels 115 jointly constitute the capillary liquid storage unit 120. The capillary liquid storage unit 120 of the present invention is mainly used to continuously supply the ink 300 to the tip of the needle tooth 1412, so that at least one of the channels 115 temporarily stores the liquid, and the liquid in the channel 115 can be guided to the needle tooth 1412 of the acupuncture part 140 under the action of gravity. Channel 115 of this embodiment may be integrally formed on the outer wall of current carrier 110 by etching, cutting, engraving or injection molding.

In one embodiment, the channels 115 of the present invention can extend vertically from the guide post 111 near the second end face 1112 to the first end face 1111. In another embodiment, the channels 115 of the present invention can extend from the guide post 111 near the second end surface 1112 to the first end surface 1111 in a spiral shape. In another embodiment, the groove 115 is an annular groove formed on the outer wall of the guide post 111, and a plurality of the annular grooves are spaced on the outer wall of the guide post.

In one embodiment, the outer wall of the flow guiding column of the present invention may be provided with a plurality of channels, and the plurality of channels may constitute the capillary liquid storage unit having a capillary action. The channel can be a needle wire or a needle tube which is externally connected to the flow guide column, and the like which can form a gap.

With continuing reference to fig. 19(a) to 19(b), in an embodiment, the diversion column of the present invention may be composed of a plurality of flat-headed needle wires 113 and/or a plurality of small cylinders 114, a plurality of flat-headed needle wires 113 and a plurality of small cylinders 114 are adjacently arranged, or a plurality of flat-headed needle wires 113 are adjacently arranged, or a plurality of small cylinders 114 are adjacently arranged, an arrangement gap between two adjacent flat-headed needle wires 113 forms a channel 115 constituting the capillary liquid storage unit 120, an arrangement gap between two adjacent small cylinders 114 forms a channel 115 constituting the capillary liquid storage unit 120, and an arrangement gap between one flat-headed needle wire 113 and one small cylinder 114 forms a channel 115 constituting the capillary liquid storage unit 120. The needle thread or the small column 114 described in this embodiment may be solid or hollow, and may form a capillary action through a gap formed by splicing, or form an auxiliary capillary action through a tube of the hollow needle thread or the hollow small column 114 on the basis.

Example 9:

the tattooing needle provided by the utility model can guide the ink 300 for tattooing into the superficial layer of the skin as a tattooing tool, so a flow guide path can be formed between the ink 300 adsorbed on the flow guide body 110 and the needle teeth 1412, and the ink 300 on the flow guide body 110 can flow to the tips of the needle teeth 1412 to be guided into the skin. Therefore, in the embroidery needle of the present invention, a corner or an edge of the base 1411 having at least one of the protrusions 141 is close to (may be substantially aligned with) an outer wall edge of the current carrier 110, so that the needle teeth 1412 disposed on the base 1411 may receive liquid from the current carrier 110. The structure design can effectively form a liquid passage, and the needle dropping empty rate is reduced. Referring to fig. 11(b), it can be seen that the outer edge of the base 1411 of the spur 141 is substantially aligned with the outer edge of the guide post 111, and the aligned portion ensures that the ink on the guide post 111 can smoothly flow to the tip of the needle tooth 1412.

In one embodiment, the base 1411 having at least one protrusion 141 is disposed at a middle portion of an end surface of the current carrier 110, and a distance between one corner or one side of the base and an edge of an outer wall of the current carrier is not more than 0.18 mm. I.e. in one case the base plate may be centrally arranged on the first end surface, but in order to obtain a better flow guiding effect a corner or an edge of the base plate is at a distance of not more than 0.18 mm from the edge of the outer wall of the flow conductor.

the needle outlet 1531 may be a flat port or a tapered port.

If the needle outlet 1531 is a flat-head port, when the fluid conductor 110 freely reciprocates at the needle outlet 1531 of the needle outlet 153 of the sleeve 150, a gap between the outer wall of the fluid conductor 110 and the inner wall of the needle outlet 153 forms a combined capillary space, liquid is temporarily stored in the combined capillary space when the needle head sucks liquid, and the liquid temporarily stored in the combined capillary space is guided to the acupuncture part 140 under the action of gravity and is guided to the skin surface layer during the penetration of the needle teeth 1412 of the acupuncture part 140.

If the needle outlet 1531 is a slope-shaped port, when the fluid conductor 110 freely reciprocates at the needle outlet 1531 of the needle outlet 153 of the sleeve 150, a gap between the outer wall of the fluid conductor 110 and the inner wall of the slope-shaped port forms a combined capillary space, liquid is temporarily stored in the combined capillary space when the needle head sucks liquid, and the liquid temporarily stored in the combined capillary space is guided to the acupuncture part 140 and is guided to the skin surface layer during the puncturing process of the needle teeth 1412 of the acupuncture part 140.
