Description

Technical Field

[0001] This invention relates to a tattooing device. Background Technology

[0002] Existing tattooing devices typically consist of a housing with a hollow space at both ends (one end of which is called the needle tip). A needle is guided within the housing to move between an extended position and a retracted position. In the extended position, the needle tip is outside the needle tip; in the retracted position, the needle tip is inside the housing. By repeatedly moving the needle forward and backward between the extended and retracted positions, the needle repeatedly penetrates and then withdraws from the skin, thus allowing a medium for application in liquid form to be introduced into the skin.

[0003] The outer shell has a certain length, and the needle body has a certain length. The opening width at one end of the outer shell is greater than the diameter of the needle body. When the needle body moves along the axial direction of the outer shell, it will deviate, causing the needle to fail to land accurately on the skin, which poses a safety hazard. Summary of the Invention

[0004] The purpose of this invention is to provide a tattooing device to solve the problem of the needle deviating when it moves along the axial direction of the housing.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A tattoo device, characterized in that it comprises:

[0007] The housing has a cavity, with openings at opposite ends of the cavity that are interconnected, and an opening in the housing that is interconnected with the cavity.

[0008] A plug is provided at one end of the cavity, the plug portion is located inside the cavity, and a through hole is provided in the middle of the plug, the through hole being concentrically arranged with the shell.

[0009] The needle assembly includes a needle body, a push rod, and an elastic sleeve. One end of the needle body is connected to one end of the push rod, and the other end of the needle body extends to the other end of the cavity. The other end of the push rod passes through the through hole. One end of the elastic sleeve is sleeved on the push rod, and the other end of the elastic sleeve is sleeved on the plug.

[0010] The positioning element is made of plastic and is fixedly installed in the cavity. The positioning element is closer to the other end of the cavity than the elastic sleeve. The center of the positioning element has a central hole for the push rod to pass through, and the central hole is concentric with the housing.

[0011] When the push rod moves axially along the housing, it can drive the other end of the needle body to extend out or retract into the cavity through the central hole from the other end opening of the cavity.

[0012] According to some embodiments of the present invention, the positioning member includes a plane and an annular side perpendicular to the plane, the annular side being connected to the plane and surrounding to form a storage space with an opening on one side, the plane being closer to the other end of the cavity than the annular side, the opening of the storage space facing one end of the cavity, the plane having the central hole, and the plane being perpendicular to the centerline of the housing.

[0013] According to some embodiments of the invention, the positioning element is detachably connected to the housing, such that the annular side of the positioning element engages with the inner wall of the housing.

[0014] According to some embodiments of the present invention, the annular side surface is provided with a groove recessed toward the center line of the housing, and the inner wall of the housing is provided with a protrusion that mates with the groove.

[0015] According to some embodiments of the present invention, the cross-section of the protrusion is arc-shaped.

[0016] According to some embodiments of the invention, the diameter of the central hole gradually decreases from one end of the housing to the other end.

[0017] According to some embodiments of the present invention, the positioning member has a protrusion on the side of its plane away from the annular side surface that protrudes toward the other end of the housing, and the protrusion has an opening that communicates with the central hole.

[0018] According to some embodiments of the present invention, the annular side surface includes a first segment and a second segment connected along its axial direction, the first segment and the second segment being distributed along the axial direction of the positioning member, the first segment being connected to the plane, and the wall thickness of the first segment being greater than the wall thickness of the second segment.

[0019] According to some embodiments of the invention, the positioning element portion is exposed from an opening in the housing.

[0020] According to some embodiments of the present invention, the positioning element has a circular cross-section.

[0021] Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art:

[0022] The tattoo device provided by this invention, by setting a positioning component, restricts the needle body and the push rod from deviating when they move in a straight line when the push rod moves along the axial direction of the housing, ensuring that the needle body extends out from the other end of the cavity and lands on the skin at the accurate position, thus ensuring high safety in use.

[0034] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] See Figures 1 to 7 The tattoo device shown is used to pierce the skin, particularly for applying permanent makeup or tattoos, or for applying active substances. The user holds the device and applies it to the human skin.

[0037] The tattoo device includes a housing 1, a plug 6, a needle assembly, and a positioning element 2. The housing 1 includes an annular circumferential surface, and the cross-section of the housing 1 is circular. The housing 1 has a hollow cavity, and the cavity has two opposite ends along its axial direction (e.g., Figure 2-3 Both ends (a refers to one end and b refers to the other end) have openings, and these openings at both ends are connected to the cavity. An opening 11 is provided on the annular circumferential surface of the shell 1, and the opening 11 is connected to the cavity.

[0038] A plug 6 is disposed at one end of the cavity, with a portion inside the cavity and the remainder outside. The plug 6 is fixed in position within the cavity, and a through hole is formed in the center of the plug 6, concentrically aligned with the housing 1. The plug 6 is detachably connected to the housing 1, meaning the plug 6 can be removed from the housing 1. In some embodiments, the plug 6 includes a first portion 61 and a second portion 62 connected to each other, distributed sequentially along the axial direction of the plug 6. The diameter of the first portion 61 is smaller than the diameter of the second portion 62. When the plug 6 is disposed at one end of the cavity, the first portion 61 is inside the cavity, and the second portion 62 is outside the cavity. The plug 6 also includes an extension 63, one end of which is connected to the second portion 62, and the other end of which extends onto the first portion 61. One end of the cavity is provided with a groove recessed towards the other end. When the plug 6 is installed at one end of the cavity, the outer periphery of the first portion 61 abuts against the inner wall of the cavity, and the extension 63 engages with the groove of the cavity.

[0039] The needle assembly includes a needle body 3, a push rod 4, and an elastic sleeve 5. One end of the needle body 3 is connected to one end of the push rod 4, and the needle body 3 extends to the other end of the cavity. The other end of the push rod 4 passes through the through hole of the plug cap 6 and extends out of the cavity. One end of the elastic sleeve 5 is fitted onto the push rod 4, and the other end of the elastic sleeve 5 is fitted onto the plug cap 6. The diameter of one end of the elastic sleeve 5 is smaller than the diameter of the other end. The elastic sleeve 5 is elastic. When the plug cap is fixed in the position of the housing, it pushes the push rod 4, and the push rod 4 can move relative to the plug cap 6.

[0040] The positioning element 2 is made of plastic and is fixedly installed in the cavity. The outer diameter of the positioning element 2 is smaller than the inner wall diameter of the cavity. The positioning element 2 is closer to the other end of the cavity than the elastic sleeve 5. A central hole is opened in the middle of the positioning element 2 for the push rod 4 to pass through. The central hole is concentric with the housing 1. When the push rod 4 moves along the axial direction of the housing 1, it can drive the other end of the needle body 3 to extend or retract into the cavity through the central hole from the other end opening of the cavity. The positioning element 2 restricts the deviation of the needle body 3 and the push rod 4 when they move in a straight line, which can ensure that the needle body 3 moves in a straight line and ensure that the needle tip of the needle body lands in the accurate position on the skin, thus ensuring high safety in use.

[0041] See Figure 2-3 The positioning component 2 includes a plane 21 and an annular side 22 perpendicular to the plane 21. The annular side 22 is connected to the plane 21 and surrounds it to form a storage space. The storage space is in communication with the cavity. The plane 21 is closer to the other end of the cavity than the annular side 22. The opening of the storage space faces one end of the cavity. A central hole is provided on the plane 21 and is in communication with the storage space. The plane 21 is perpendicular to the center line of the housing 1.

[0042] The positioning element 2 protrudes from the opening 11 of the housing 1, that is, both the flat part and the annular side 22 of the positioning element 2 protrude from the opening 11 of the housing 1. The advantage of this arrangement is that the flat part of the positioning element 2 and the other end of the cavity of the housing 1 form an accommodating space, and the beauty liquid can flow into the accommodating space from the opening 11 of the housing 1. When the push rod 4 moves along the axial direction of the housing 1, the beauty liquid will flow to the needle tip of the needle body. In addition, the positioning element 2 is provided, and the space between the positioning element 2 and the needle outlet at the other end of the housing 1 is formed for the beauty liquid to flow, preventing the beauty liquid from flowing to the elastic sleeve 5. This will not corrode the elastic sleeve 5 and improve the service life of the device.

[0043] The positioning element 2 is detachably connected to the housing 1, such that the annular side 22 of the positioning element 2 is engaged with the inner wall of the housing 1, which makes it easy to install the positioning element 2 into the cavity of the housing and remove the positioning element 2 from the cavity of the housing 1.

[0044] The annular side 22 of the positioning member 2 is provided with a groove that is recessed towards the center line of the housing 1. The groove is arranged in a circle around the outer periphery of the annular side 22. The inner wall of the housing 1 is provided with a protrusion 12 that cooperates with the groove. The protrusion 12 protrudes from the inner wall surface of the housing 1. When the positioning member 2 is installed in the cavity of the housing 1, the positioning member 2 is held in hand so that the plane of the positioning member 2 enters the cavity from one end of the cavity before the annular side. Then, the plane of the positioning member 2 is pushed by the auxiliary rod to make the positioning member 2 move along the axial direction of the housing 1 until the groove of the positioning member 2 is engaged with the protrusion 12 on the inner wall of the cavity. At this time, the positioning member 2 is fixed in position in the cavity and does not shake. When the positioning member 2 is removed, the auxiliary rod can be inserted into the cavity from the other end of the cavity to push the plane of the positioning member 2 to move it towards one end of the cavity until the positioning member 2 is removed from the cavity.

[0045] See Figure 3 The diameter of the central hole of the positioning element 2 gradually decreases from one end of the housing 1 to the other end, that is, the larger diameter part faces one end of the housing 1 and the smaller diameter part faces the other end of the housing 1. When the push rod 4 moves from the other end of the cavity to one end of the cavity, it is convenient for the push rod 4 to move along the central hole.

[0046] The annular side of this example includes a first segment 221 and a second segment 222 connected to each other. The first segment 221 and the second segment 222 are distributed along the axial direction of the positioning member 2. The first segment 221 is connected to the plane, and the second segment 222 is closer to one end of the cavity than the first segment 221. The diameter of the first segment 221 of the positioning member gradually decreases from one end of the housing 1 to the other end; the diameter of the second segment 222 is the same. This arrangement facilitates the installation of the positioning member 2. The first segment 221 enters the cavity of the housing 1 first, that is, the smaller diameter part enters the cavity of the housing 1 first, which allows for faster installation.

[0047] The wall thickness of the first segment 221 is greater than the wall thickness of the second segment 222. See [reference needed]. Figure 3 The positioning component 2 has a first surface 24 and a second surface 25 within its storage space. A connecting surface exists between the first surface 24 and the second surface 25. This connecting surface is inclined, and it slopes from one end of the connecting surface near the plane to the other end from the other end of the housing 1 towards that end. The connecting surface and the second surface 25 correspond to the first segment. Figure 2-3 In the state shown, the distance between the connecting surface and the outer peripheral wall of the annular side 22 is greater than the wall thickness of the second section. This setting helps to enhance the strength of the positioning component 2, and makes the whole device more stable when the needle body moves in a straight line without deviating, which is conducive to the user's stable operation.

[0048] In some embodiments, the side of the plane of the positioning member 2 away from the annular side is provided with a protrusion 23 that protrudes towards the other end of the housing 1. The protrusion 23 has an opening that communicates with the central hole. The diameter of the protrusion 23 is smaller than the diameter of the annular side. The protrusion serves as a guide.

[0049] In this example, the housing 1, plug 6, and push rod 4 are made of plastic, while the needle body is made of metal.

[0050] The tattoo device provided in this example, by setting a positioning component, restricts the needle and the push rod from deviating when moving in a straight line as the push rod moves along the axial direction of the housing, ensuring that the needle extends out of the other end of the cavity and lands on the skin in an accurate position, thus ensuring high safety in use.

[0051] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
