[0002] In the prior art, an integrated tattoo needle is composed of components such as a syringe barrel, a needle tip, a guide sleeve, an elastic membrane, a guide rod, and a tail cap. The internal structure of most tattoo needles (round needles) basically adopts the form of embedding the guide sleeve. This structure of the embedded guide sleeve is a split structure. During the production and processing process, it is necessary to manually embed the guide sleeves into the syringe barrel one by one, resulting in low production efficiency. Or during the assembly process, the guide sleeve is not embedded in place, resulting in poor stability. During use, there will be phenomena such as the guide sleeve loosening, falling off, or shifting, causing the guide rod to get stuck or jam when passing through the guide sleeve or the guide sleeve moving together with the guide rod, resulting in the inability to use the tattoo needle.

[0003] Therefore, how to improve the stability of the guide rod is a technical problem that those skilled in the art need to solve at present. Summary of the Utility Model

[0034] In order to enable those skilled in the art in this technical field to better understand the solution of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "outer" and "inner" etc. are based on the orientation or positional relationships shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present utility model.

[0036] The purpose of the present utility model is to provide an integrated tattoo needle that can improve the stability of the guide rod.

[0037] To achieve the above purpose, the present utility model provides the following technical solutions:

[0038] Please refer to Figures 1 to 2, this embodiment provides an integrated tattoo needle, including: a syringe barrel 100, a needle tip 200, a catheter 300, and a needle guiding assembly; an air hole 110 is formed on the side wall of the syringe barrel 100; the needle tip 200 is arranged at the bottom of the syringe barrel 100; the catheter 300 is a cylindrical structure and is nested inside the syringe barrel 100, and the catheter 300 is coaxially arranged at the connection between the syringe barrel 100 and the needle tip 200; the needle guiding assembly is sleeved inside the syringe barrel 100, and the needle guiding assembly passes through the catheter 300 and extends out from the needle tip 200, and an elastic film 130 for resetting it is arranged on the outer periphery of the needle guiding assembly; the syringe barrel 100, the needle tip 200, and the catheter 300 are of an integrated structure.

[0039] Specifically, as Figure 2 shown, the syringe barrel 100 is a cylindrical structure with a hollow interior, which can hold pigments and install a needle guiding assembly for tattooing. The needle guiding assembly moves up and down inside the syringe barrel 100. A needle tip 200 with a conical structure is arranged at the lower end of the syringe barrel 100. The needle tip 200 is also a hollow structure. The needle guiding assembly will extend out of the needle tip 200 during tattooing. The elastic film 130 is arranged on the needle guiding assembly and has a certain elasticity. After each extension of the needle guiding assembly, it can be reset and retracted; it should be noted that in order to enable the needle guiding assembly to move up and down stably and eliminate the swing of the needle guiding assembly to the greatest extent, a catheter 300 is arranged at the connection between the syringe barrel 100 and the needle tip 200. The catheter 300 has a certain length, and the needle guiding assembly moves up and down inside it. In this way, the operation of the needle guiding assembly is smoother and more stable.

[0040] In addition, in order to enable the needle guiding assembly to smoothly bring out the pigments in the syringe barrel 100 when extending out from the needle tip 200, air holes 110 with a smaller diameter are arranged on the side wall of the syringe barrel 100, and air can enter the interior of the syringe barrel 100 through the air holes 110.

[0041] In addition, the syringe barrel 100, the needle tip 200, and the catheter 300 in the above structure are of an integrated structure. The syringe barrel 100, the needle tip 200, and the catheter 300 do not need to be manually connected, that is, there is no need to manually embed the catheter 300 into the syringe barrel 100 one by one, which has a low production efficiency. Moreover, it can avoid mistakes during the assembly process, resulting in the catheter 300 not being embedded in place and having poor stability. There will be no phenomenon of the catheter 300 loosening, falling off, or shifting during use, and there will be no situation where the needle guiding assembly gets stuck or jammed when passing through the catheter 300 or the catheter 300 moves along with the needle guiding assembly. With such a setting, the operation of the needle guiding assembly can be more fluent when the tattoo needle is in use.

[0042] That is to say, the syringe barrel 100, the needle tip 200 and the catheter 300 of the tattoo needle provided by the present utility model are of an integral structure, and the catheter 300 is also placed in front, that is, the catheter 300 is installed at the connection between the syringe barrel 100 and the needle tip 200, and the catheter 300 is connected to the needle outlet channel of the needle tip 200. During use, the needle guiding assembly can operate more stably and smoothly under the guidance of the catheter 300. At the same time, it effectively reduces the manufacturing difficulty of the tattoo needle, reduces the production cost and improves the production efficiency.

[0043] Preferably, the needle guiding assembly includes a guide rod 410 and a needle wire 420; the guide rod 410 is inserted through the middle of the end cap 120 at the top of the syringe barrel 100, and the guide rod 410 is coaxially arranged with the syringe barrel 100 and the catheter 300; the needle wire 420 is detachably installed at one end of the guide rod 410 away from the needle tip 200, and the needle wire 420 passes through the needle tip 200.

[0044] As Figure 1 As shown in the figure, the needle guiding assembly includes a guide rod 410 and a needle wire 420. The needle wire 420 is coaxially installed at the lower end of the guide rod 410 and can move up and down with the guide rod 410. The lower end of the guide rod 410 moves in the catheter 300, and the needle wire 420 can extend through the needle tip 200. The upper end of the guide rod 410 is guided and limited by the end cap 120. The upper end of the syringe barrel 100 is provided with an end cap 120, and a through hole is opened in the center of the end cap 120 for supporting the guide rod 410 in cooperation with the catheter 300.

[0045] Preferably, a guiding hole 121 extending along the length direction of the guide rod 410 is provided in the center of the end cap 120, and the guiding hole 121 is used to guide the movement of the guide rod 410.

[0046] In this embodiment, in order to further increase the stability of the guide rod 410 during movement and prevent it from swinging, a through hole is provided in the middle of the end cap 120 close to the guide rod 410, and its inner wall is smooth. This through hole is the guiding hole 121, and the axis of the guiding hole 121, the catheter 300 and the needle tip 200 are all on the same straight line; there is a certain distance between the end cap 120 and the catheter 300, and the two form two-point support. Moreover, when the guiding hole 121 and the catheter 300 are in contact with the guide rod 410, they are in surface-to-surface contact, which further increases the stability of the guide rod 410 during movement.

[0047] Preferably, an elastic film 130 is arranged inside the syringe barrel 100 and sleeved on the outer periphery of the guide rod 410. A flange 411 is provided on the guide rod 410, and the elastic film 130 abuts against the flange 411. The elastic film 130 is used for the reset of the guide rod 410 after it extends out.

[0048] Based on the above specific embodiments, the elastic film 130 is a silicone conical barrel elastic film 130 with through holes. The elastic film 130 is sleeved on the guide rod 410 and is connected to the end cover 120 at the rear end. The structure is simple and the connection is convenient; it has good elasticity and flexibility, and has a good reset effect on the guide rod 410; it has a long service life. A flange 411 is provided between the end cover 120 and the through hole of the elastic film 130 on the guide rod 410. The flange 411 has an abutting surface that abuts against the elastic film 130. Such a setting can enable the elastic film 130 to drive the guide rod 410 to automatically reset when rebounding; in addition, the flange 411 also plays a sealing role and can prevent the ink in the syringe 100 from flowing out from the connection between the guide rod 410 and the elastic film 130; of course, the specific position of the flange 411 provided on the guide rod 410 can be adjusted according to the actual situation.

[0049] Preferably, a spherical portion 412 is provided at the end of the guide rod 410 where the needle wire 420 is installed. The spherical portion 412 is located inside the catheter 300, and the spherical portion 412 is used to reduce the friction generated when the guide rod 410 moves inside the catheter 300.

[0050] It can be understood that the guide rod 410 is in direct contact with the catheter 300, and when the two move relative to each other, friction will be generated, and the guide rod 410 will move up and down repeatedly. Therefore, in order to reduce the friction between the guide rod 410 and the catheter 300 and extend the service life of the catheter 300 and the guide rod 410, the diameter of the rod body of the guide rod 410 is set to be smaller than the diameter of the catheter 300, and the lower end of the guide rod 410 is provided with a spherical structure. The diameter of the spherical portion 412 is exactly adapted to the catheter 300. With such a setting, when the guide rod 410 moves up and down, only the spherical portion 412 moves up and down inside the catheter 300. Compared with the friction between the rod body and the inner wall of the catheter 300, this can reduce the wear of the catheter 300 and the guide rod 410, and thus improve their service life.

[0051] Preferably, a diversion groove 310 along its axial direction is provided on the side wall of the catheter 300, and the diversion groove 310 communicates the inside of the syringe 100 with the inside of the catheter 300.

[0052] As Figure 2 shown, a diversion groove 310 along its axial direction is provided on the side wall of the catheter 300. Such a setting can communicate the inside of the syringe 100 and the inside of the catheter 300, so that the pigment in the syringe 100 can enter the inside of the catheter 300, and then be transmitted to the needle wire 420 by the spherical portion 412 for tattooing, enabling the needle wire 420 to smoothly carry out the tattoo pigment.

[0053] Preferably, the outer diameter of the catheter 300 gradually expands in the direction close to the needle tip 200.

[0054] As Figure 1 and Figure 2As shown, the outer diameter of the catheter 300 gradually expands downward in diameter. As a result, the space formed between the outer wall of the catheter 300 and the inner wall of the syringe 100 gradually decreases downward, while the upper and lower widths of the flow guiding groove 310 formed on the side wall of the catheter 300 are the same, which will make it easier for the pigment to flow into the catheter 300 from the flow guiding groove 310 downward, further increasing the smoothness of ink output during the use of the needle wire 420.

[0055] Preferably, the spherical portion 412 is in clearance fit with the catheter 300.

[0056] It can be understood that the spherical portion 412 needs to transfer the pigment to the needle wire 420. Therefore, there should be a gap between the spherical portion 412 and the catheter 300 to allow the pigment to flow in.

[0057] Preferably, the syringe 100, the needle tip 200 and the catheter 300 are integrally formed by injection molding.

[0058] In this embodiment, the syringe 100, the needle tip 200 and the catheter 300 are preferably manufactured by injection molding. This processing method is simple and fast, and the production efficiency is relatively high.

[0059] Preferably, the materials of the syringe 100, the needle tip 200 and the catheter 300 are all PC materials.

[0060] In addition, in this embodiment, the materials of the injection molded syringe 100, the needle tip 200 and the catheter 300 are specifically PC materials. This material has good mechanical properties, can also resist heat, has good dimensional stability and impact resistance, is also very convenient for processing, has high processing accuracy during injection molding, high stability, and is not easy to deform.

[0061] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0062] The various embodiments in this specification are described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
