Description

Technical Field

[0001] The present application relates to the field of low-voltage electrical equipment and is a tattoo needle sleeve. Background Art

[0002] Tattooing is to pierce the human skin to allow the pigment to penetrate and dye, thereby forming a specific color and specific lines on the skin. The tattoo device used for tattooing often includes a motor drive device and a needle cover at the front, and the needle cover is detachably mounted on the motor drive device. The needle cover is a disposable item. After the tattoo is completed, it is basically removed from the motor drive device and discarded. In addition, the quality of the tattoo is closely related to whether the needle cover structure is reasonable.

[0003] Existing tattoo needle sleeves, such as a tattoo device needle sleeve structure disclosed in CN115120865A, include: a shell, a plug cover, a push rod, a reset sleeve, a plug column, and a needle. The shell is a tubular structure, the head of the shell forms a needle mouth, the rear of the shell has a through hole, and the plug cover is plugged into the rear of the shell. One end of the push rod penetrates the sega and is exposed at the rear of the shell, and this part is used to connect with the output part of the motor drive part. The other end of the push rod extends into the shell. The plug column is a metal rod, which is located inside the shell and one end is connected to the push rod. The needle is connected to the other end of the plug column, and the tip of the needle is located near the needle mouth of the shell. The reset sleeve connects the push rod to the plug cover. When the push rod is driven by the output part of the motor drive part to extend toward the inside of the shell, the reset sleeve will be stretched to generate a reset force. When the push rod is driven by the output part of the motor drive part to extend toward the outside of the shell again, the reset force of the reset sleeve can accelerate the movement of the push rod.

[0004] When this needle sleeve is used, the output part of the external motor driving part acts on the push rod, causing the push rod to reciprocate, thereby causing the needle to frequently extend and retract the needle mouth. When the needle is extended, it pierces the skin to perform tattooing.

[0005] The plug-in column in this structure is a straight rod. The inventor found that this rod has little elasticity when piercing the skin, while the skin has a certain elasticity. When the needle pierces the skin, the force of the skin will cause the needle to be bounced back a small distance. Although this distance is very small, it will directly affect the piercing of the skin and the flow of pigment into the skin.

[0006] Therefore, how to design a novel tattoo needle sleeve has become a direction worthy of research. Summary of the invention

[0007] In view of this, the purpose of the present application is to overcome the deficiencies in the prior art and to provide a tattoo needle sleeve that can reduce the effect of skin elasticity on the needle as much as possible.

[0008] The present application provides: a tattoo needle sleeve, which comprises a needle tube, a plug cover, a reset member, a push rod, a metal rod and a needle; the needle tube is a hollow structure, the size of the front part of the needle tube is gradually reduced to form a needle mouth, and the rear part of the needle tube has an opening; the plug cover is located at the rear part of the needle tube, and is used to block the opening; the push rod penetrates the plug cover and is slidably arranged, the first end of the push rod is located in the needle tube, and the second end of the push rod is located outside the needle tube; the third end of the metal rod is connected to the first end of the push rod; the head of the needle is located near the needle mouth, and the tail of the needle is connected to the fourth end of the metal rod; the push rod exhibits reciprocating motion under external force driving, so that the head of the needle retracts and extends out of the needle mouth; the reset member is connected between the push rod and the plug cover, and accelerates the movement of the push rod when the needle moves in the direction of retracting the needle mouth; wherein the third end and the fourth end of the metal rod are both straight rod-shaped structures, and the metal rod also includes a first bending structure connected between the third end and the fourth end.

[0009] With this structure, due to the design of the first bending structure, the metal rod has better elasticity than a straight rod. In this way, when the needle pierces the skin, even if the elasticity of the skin causes the metal rod to rebound slightly, the elasticity of the first bending structure can also generate a certain reaction force to make the needle act toward the skin. The contact force and distance between the needle and the skin in this structure will be better than the existing technology. At the same time, since the needle is in direct contact with the skin, the metal rod here is connected to the needle and is also very close to the skin, so the elastic force generated by this metal rod will be extremely obvious.

[0010] In some embodiments of the present application, the total length of the first bending structure is greater than the length of the third end, and greater than the length of the fourth end.

[0011] By adopting this structure and ensuring the length of the first bending structure, it will be beneficial to ensure that the first bending structure has sufficient elasticity.

[0012] In some embodiments of the present application, the first bending structure is V-shaped, and the angle of the V-shape is an obtuse angle; or, the first bending structure is arc-shaped, and the angle between the tangent of the arc near the third end and the third end is an obtuse angle, and the angle between the tangent of the arc near the fourth end and the fourth end is an obtuse angle.

[0013] The design of the above-mentioned obtuse-angle structures will be beneficial to the processing of the first bending structure.

[0014] In some embodiments of the present application, a second bending structure is further included, the second bending structure forms a continuous bend with the first bend, and the bending direction of the second bending structure is opposite to that of the first bending structure.

[0015] The continuous bending structure with opposite bending directions further improves the elastic force and ensures the contact force with the skin.

[0016] In some embodiments of the present application, the total length of the second bending structure and the first bend is greater than the length of the third end, and greater than the length of the fourth end.

[0017] The use of such a length structure will help ensure that the first bending structure has sufficient elasticity.

[0018] In some embodiments of the present application, the first bend and the second bend are both V-shaped, and the angle of the V-shape is 40°-105°.

[0019] In some embodiments of the present application, the sharp corners of the first bend and the second bend are arc-shaped.

[0020] The arc-shaped design is conducive to product processing and avoids sharp corners scratching other parts.

[0021] In some embodiments of the present application, the second bending structure and the first bending structure are both U-shaped structures; the first bending structure is connected to the third end, and the connection between the third end and the first bending structure is an obtuse angle; the second bending structure is connected to the fourth end, and the connection between the fourth end and the second bending structure is an obtuse angle.

[0022] In some embodiments of the present application, the metal rod is made of spring steel or music steel; or, the reset member is a spring or an elastic sleeve; or, the cross-section of the needle mouth is circular, and the head of the needle is composed of at least two sub-needle tips, which are closely located together at the needle mouth; or, the cross-section of the needle mouth is a flat hole, and the head of the needle is composed of at least one row of sub-needle tip groups, each row of sub-needle tip groups contains at least four sub-needle tips, and all sub-needle tips are located at the needle mouth.

[0023] There are many types of materials to choose from. Spring steel and piano steel are both preferred elastic hard materials. There are also many types of reset parts to choose from. Elastic sleeves and springs are both acceptable. There are many types of needles to choose from. They can be needles that look like a needle with each needle tip close together at the needle mouth, or they can be row needles.

[0024] A tattoo device comprises a motor drive unit, wherein the tattoo needle sleeve mentioned above is included; the tattoo needle sleeve and the motor drive unit are detachably matched, and the output end of the motor drive unit is connected to a push rod for driving the push rod to realize reciprocating motion.

[0025] With the tattoo device of the above structure, the metal rod has better elasticity than a straight rod due to the design of the first bending structure. Thus, when the needle pierces the skin, even if the elasticity of the skin causes a slight rebound of the metal rod, the elasticity of the first bending structure can also generate a certain reaction force to make the needle act toward the skin. The contact force and distance between the needle and the skin of such a structure will be better than the existing technology. At the same time, since the needle is in direct contact with the skin, the metal rod here is connected to the needle and is also very close to the skin, so the elastic force generated by this metal rod will be extremely obvious.

[0039] Example

[0040] like Figure 1-Figure 6 As shown, the embodiment of the present application is a tattoo needle cover 100, which is a disposable component and is generally used to be installed in the motor drive unit 200 of a tattoo device.

[0041] The tattoo needle sleeve 100 comprises a needle tube 101 , a plug cover 102 , a push rod 103 , a metal rod 104 , a needle 105 and a resetting member 106 .

[0042] The needle tube 101 is made of plastic and has a hollow structure. Its size gradually decreases at the front of the needle tube 101 to form a needle mouth 101a. An opening 101b is provided at the rear of the needle tube 101. The opening 101b is connected to the hollow part, so that the remaining components inside the needle tube 101 can be installed through the opening 101b.

[0043] The plug cover 102 is installed at the rear part of the needle tube 101 to close the opening 101b. A through hole 102a is provided on the plug cover, and the through hole 102a is communicated with the hollow part of the needle tube 101.

[0044] The push rod 103 is made of plastic, passes through the through hole 102a, and the first end 103a of the push rod 103 is exposed outside the needle tube 101, and the second end 103b is located inside the needle tube 101. The push rod 103 here is used to connect with the motor driving unit 200, and can reciprocate due to the action of the motor driving unit 200.

[0045] The reset member 106 is an elastic sleeve, such as a rubber sleeve, in this embodiment. One end of the rubber sleeve is sleeved on the push rod 103, and the other end of the rubber sleeve is connected to the plug cover 102. In this way, when the push rod 103 moves toward the needle tube 101, the rubber sleeve will be stretched, and when the push rod 103 moves in the reverse direction, the rubber sleeve will accelerate the reverse movement of the push rod 103. Of course, the rubber sleeve here can also be replaced by a spring, which can also achieve the reset effect.

[0046] The metal rod 104 includes a third end 104a and a fourth end 104b. The third end 104a and the fourth end 104b are only used to distinguish from the first end 103a and the second end 103b above, and the metal rod 104 itself does not have four ends. The third end 104a and the fourth end 104b are both straight rod-shaped structures, which can also be understood as a straight line. The third end 104a here is used to be plugged into the first end 103a of the push rod 103, so that the metal rod 104 is connected to the push rod 103, and the fourth end 104b here is connected to the needle 105.

[0047] The needle 105 includes a head 105a and a tail 105b, wherein the tail 105b is connected to the fourth end 104b of the metal rod 104 by welding. The head 105a is located near the needle mouth 101a, so that whenever the push rod 103 moves toward the needle tube 101, the needle 105 will pierce out from the needle mouth 101a, and whenever the push rod 103 moves in the opposite direction, the needle 105 will retract into the needle mouth 101a, so that the reciprocating movement can realize the tattoo.

[0048] Here, there are many types of needles 105, and two types of needles 105 are exemplified below:

[0049] like Figure 1-2 As shown, the needle head 105 in this embodiment is a row of needles. In this embodiment, the cross section of the needle mouth 101a is a flat hole. The head 105a of the needle head 105 is composed of two rows of sub-needle tip groups. There are 7 sub-needle tips 105a1 in one row of sub-needle tip groups, and 8 sub-needle tips 105a1 in the other row of sub-needle tip groups. All sub-needle tips 105a1 are located at the needle mouth 101a. Of course, the sub-needle tips 105a1 of this needle head 105 can also be a group, and there can be four sub-needle tips 105a1 in each row of sub-needle tip groups.

[0050] like Figure 6 As shown, the needle head 105 in this embodiment looks like "a needle" from a distance. In this embodiment, the cross section of the needle mouth 101a is circular. Here, the head 105a of the needle head 105 is composed of five sub-needle tips 105a1, which are closely connected, so the whole is relatively concentrated and looks like "a needle". These sub-needle tips 105a1 are all located at the needle mouth 101a. Of course, the number of sub-needle tips 105a1 of this needle head 105 can also be 2.

[0051] In order to increase the contact force between the needle 105 and the skin and improve the tattoo effect, a bending structure is provided on the metal rod 104 to make the metal rod 104 have a certain elasticity. The bending structures of several embodiments are introduced below. With this structure, due to the design of the first bending structure 104c, the metal rod 104 has better elasticity than a straight rod.

[0052] like Figure 3As shown, in this embodiment, there is also a first bending structure between the third end 104a and the fourth end 104b of the metal rod 104, that is, the third end 104a and the fourth end 104b are connected through the metal rod 104. In this embodiment, the first bending structure is in the shape of an arc, and the angle between the tangent line of the arc near the third end 104a and the third end 104a is an obtuse angle A, and the angle between the tangent line of the arc near the fourth end 104b and the fourth end 104b is an obtuse angle B. Here, the total length of the first bending structure 104c is greater than the length L1 of the third end 104a, and is also greater than the length L2 of the fourth end 104b. Of course, the first bending structure 104c of this structure can also be replaced by a V-shape.

[0053] like Figure 4-5 As shown, in this embodiment, the third end 104a and the fourth end 104b of the metal rod 104 have both a first bending structure 104c and a second bending structure 104d. In this embodiment, the first bending structure 104c and the second bending structure 104d form a continuous bend, and the bending directions of the two bending structures are opposite. In this way, the total length L of the second bending structure 104d and the first bend is greater than the length L1 of the third end 104a, and greater than the length L2 of the fourth end 104b.

[0054] In this embodiment, the first bend and the second bend can both be V-shaped, and the angle C of the V-shaped structure is 40°-105°. Of course, the first bend and the second bend can both be U-shaped structures, and the first bend structure 104c is connected to the third end 104a, and the third end 104a and the first bend structure 104c are connected at an obtuse angle C, and the second bend structure 104d is connected to the fourth end 104b, and the fourth end 104b and the second bend structure 104d are connected at an obtuse angle D.

[0055] Regardless of the above-mentioned method, the material of the metal rod 104 can be selected to be spring steel or music steel.

[0056] No matter which bending method is mentioned above, it can bring about an effect, that is, when the needle 105 pierces the skin, even if the elasticity of the skin causes the metal rod 104 to rebound slightly, the existence of the bend will generate a certain elasticity, and a certain reaction force will be generated to make the needle 105 act toward the skin. In this structure, the contact force and distance between the needle 105 and the skin will be better than the existing technology. At the same time, because the needle 105 is in direct contact with the skin, the metal rod 104 here is connected to the needle 105 and is also very close to the skin, so the elastic force generated by this metal rod 104 will be extremely obvious.

[0057] like Figure 7As shown, the tattoo needle cover 100 can be used in a tattoo device. The tattoo device includes a motor drive unit 200, and the tattoo needle cover 100 and the motor drive unit 200 are detachably connected. Here, this connection method and the motor drive unit 200 are prior art and are not described in detail. The motor drive unit 200 acts on the push rod 103 to achieve reciprocating motion of the needle 105, thereby completing the tattoo work.

[0058] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples described in this specification without contradiction.
