Description

Technical Field

[0001] This utility model belongs to the field of tattoo / permanent makeup / hair tattooing technology, and specifically relates to a large-capacity integrated tattoo needle and tattooing device. Background Technology

[0002] When using a conventional one-piece needle to create designs on human skin, it's necessary to frequently dip the needle in specialized pigment ink before applying the design. The typical one-piece needle design features a window in the plastic shell connecting the internal space to the outside atmosphere. Ink is drawn into the shell through the repeated movement of the needle wire, and capillary action due to atmospheric pressure draws ink into the gap between the stainless steel needle wire and the plastic shell. This limits the ink capacity. Once the ink level exceeds a certain point, excess ink will be carried out of the needle due to gravity, atmospheric pressure, or the high-frequency reciprocating motion of the needle wire. This can also cause ink dripping or splattering, affecting the tattoo artist's efficiency. Taking a circular one-piece needle (with circular dotting patterns) as an example, the length of a straight line drawn by a regular one-piece needle with ink in one dip is about 20-45cm. If you are doing a large-area tattoo, it will reduce the tattooing efficiency. When the ink is about to run out during the tattooing process, the color of the lines will obviously become lighter. The next time you dip the needle in ink, you need to connect the lighter lines and draw them again. The quality of the overlapping lines is not high. Frequent dipping and drawing will reduce the overall quality of the tattoo pattern and will also cause more damage to the skin. Summary of the Invention

[0003] The purpose of this invention is to provide a large-capacity integrated tattoo needle that can pre-store a large amount of ink, reducing the frequency of ink replenishment.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a large-capacity integrated tattoo needle, comprising:

[0005] The needle shell has a pointed nozzle at its front end, an ink storage cavity in its middle and a central opening on its circumference, and an open rear end.

[0006] A rear cover is provided on the opening at the rear end of the needle housing;

[0007] A needle wire, which is installed inside the needle housing and can extend from the nozzle of the needle housing;

[0008] The transmission part has its rear end inserted through the rear cover and its front end fixedly connected to the needle wire. The drive motor drives the transmission part to reciprocate, thereby driving the needle wire to reciprocate to complete the puncture action.

[0009] The integrated needle also includes a one-way valve located on the central opening and a spring sleeve fitted onto the transmission part or needle wire and sealed against the inner wall of the needle housing. During tattooing, the drive motor is activated, and the needle wire is driven by the transmission part to extend from the nozzle. At the same time, the spring sleeve moves downward to compress the air in the ink storage chamber, causing the air to be discharged through the one-way valve, creating a negative pressure in the ink storage chamber. When the transmission rod drives the needle wire back into the ink storage chamber, the one-way valve closes, and the gap between the needle wire and the nozzle is partially sealed by ink, preventing ink from flowing out while allowing air to be replenished. When ink needs to be drawn into the ink storage chamber, the nozzle is placed into a container filled with ink. When the needle wire retracts into the ink storage chamber, the ink in the container is drawn into the ink storage chamber due to the negative pressure. The ink is drawn in after the needle wire reciprocates multiple times.

[0010] In another embodiment, the check valve is a silicone check valve.

[0011] In another embodiment, the spring sheath is made of silicone, with its rear end sealed onto the end of the rear cover located inside the needle housing and its front end sealed onto the transmission part.

[0012] In another embodiment, the transmission part includes a transmission rod, the middle section of which is a quadrangular prism. The rear cover is provided with a quadrangular prism-shaped hole that matches the middle section of the transmission rod, which can further play a guiding role.

[0013] In another embodiment, a first annular sealing ring is formed below the middle section of the transmission rod, and the front end of the spring sleeve is sealed on the first sealing ring. This not only achieves sealing, but the tensioned spring sleeve also ensures that the transmission rod always tends to move towards the rear.

[0014] In another embodiment, the first sealing ring is a frustoconical shape that is thicker at the front and thinner at the rear.

[0015] This utility model also provides a tattooing device, which includes a gripping part, a driving part installed in the gripping part, and an integrated tattoo needle. The gripping part is cylindrical. The driving part includes a driving motor installed in the gripping part, an eccentric wheel fixed on the driving motor, a follower wheel sleeved on the eccentric wheel and rotatably connected to the eccentric wheel, a flexible transmission steel wire connected at its rear end between the follower wheel and the integrated tattoo needle, and a power rod connected to the front end of the transmission steel wire. The integrated tattoo needle is any of the aforementioned large-capacity integrated tattoo needles. The front end of the power rod presses against the rear end face of the integrated tattoo needle. When the driving motor rotates, the eccentric wheel drives the follower wheel to reciprocate, which in turn drives the transmission steel wire to reciprocate, and finally drives the integrated tattoo needle to reciprocate.

[0016] In another embodiment, the front end of the grip is provided with a front mounting hole, and a middle mounting hole communicating with the front mounting hole is provided inside the grip and located behind the front mounting hole. The drive motor is installed inside the grip and located behind the middle mounting hole. The rear end of the integrated tattoo needle and the power rod pass through the middle mounting hole. The power rod has a spherical guide head. The center of the rear end face of the transmission rod is provided with a recessed and arc-shaped guide surface. The guide head presses against the guide surface. The rear cover is fixedly installed in the front mounting hole. The guide head is located in the central mounting hole and is clearance-fitted with the central mounting hole, so that when the guide head pushes the guide surface at any angle, it is pressed against the center position of the guide surface. The drive motor drives the power rod to reciprocate. When the power rod moves forward, it pushes the transmission rod forward, which in turn drives the needle wire to extend out of the nozzle of the needle shell. At the same time, the spring sleeve is stretched. When the power rod moves backward, the spring sleeve retracts. Since the front end of the spring sleeve is tightly fitted on the first sealing ring of the transmission rod, the retraction of the spring sleeve will pull the transmission rod back, that is, pull the needle wire back into the needle shell.

[0017] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This integrated tattoo needle provides more ink storage capacity, reduces the frequency of dipping ink for drawing, improves work efficiency, and allows more energy to be focused on drawing; at the same time, it reduces the damage caused by secondary drawing on the skin, such as when the ink runs out and the lines fade.

[0025] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings. Example

[0026] like Figure 1-4 As shown, the large-capacity tattoo needle includes: needle housing 1, back cover 6, needle wire 3, transmission part, one-way valve 2, and spring sleeve 5.

[0027] The needle housing 1 has a pointed nozzle 12 at its front end, an ink storage cavity 13 in its middle, and a central opening 11 on its circumferential surface. Its rear end is open. A rear cover 6 is fitted over the open rear end of the needle housing 1. The needle wire 3 is installed inside the needle housing 1 and extends from the nozzle 12. The rear end of the transmission unit passes through the rear cover 6, and its front end is fixedly connected to the needle wire 3. A drive motor drives the transmission unit to reciprocate, thereby driving the needle wire 3 to reciprocate to complete the puncture action. A one-way valve 2 is located on the central opening 11; it is a silicone one-way valve. A spring sleeve 5 is fitted onto the transmission unit or... The needle wire 3 is sealed and fitted to the inner wall of the needle housing 1. The spring sleeve 5 is made of silicone, with its upper end sealed on the end of the rear cover 6 located inside the needle housing 1 and its lower end sealed on the transmission part. The transmission part includes a transmission rod 4, the middle section of which is a quadrangular prism. The rear cover 6 is provided with a quadrangular prism-shaped square hole 15 that matches the middle section of the transmission rod 4. A first sealing ring 16 is formed below the middle section of the transmission rod 4. The first sealing ring 16 is a frustum-shaped cone with a thicker front side and a thinner rear side. The lower end of the spring sleeve 5 is sealed on the first sealing ring 16.

[0028] During tattooing, the drive motor is activated, and the needle 3 is driven by the transmission unit to extend from the mouthpiece 12. At the same time, the spring sleeve 5 descends and squeezes the air in the ink storage chamber 13, causing the air to be discharged through the one-way valve 2, creating a negative pressure in the ink storage chamber 13. When the transmission rod 4 drives the needle 3 back into the ink storage chamber 13, the one-way valve 2 closes, and the gap between the needle 3 and the mouthpiece 12 is partially sealed by ink, keeping the ink from flowing out while allowing air to be replenished. When ink needs to be drawn into the ink storage chamber 13, the mouthpiece 12 is placed into the ink container 7. When the needle 3 retracts into the ink storage chamber 13, the ink 8 in the container 7 is drawn into the ink storage chamber 13 due to the negative pressure. The needle 3 completes the ink drawing process after reciprocating multiple times.

[0029] With the sheath retracted, the internal volume of the housing is V1, and the internal pressure is P1. With the sheath extended, the internal volume of the housing is V2, and the internal pressure is P2. The increased internal pressure of the housing when the sheath is extended is ΔP, the compressed volume is ΔV, the volume discharged at the valve is ΔV1, the volume discharged at the needle nozzle gap A is ΔV2, the standard atmospheric pressure is P0, and the valve opening pressure is P. k The frequency of the reciprocating motion of the needle is f. Based on the above method of using a large-capacity tattoo needle: make 3 HZ≤f≤250HZ, P0≤Pk≤2 / 3△P or 0<△V2≤0.05△V.

[0030] According to the law of state in physics, when the ambient temperature remains constant, the pressure of a gas is inversely proportional to its volume change, i.e., P1V1 = P2V2. Therefore, ΔP = P2 - P1 = P2 - P2 × V2 / V1. Based on the above method of using a large-capacity tattoo needle: ensure P0 ≤ P k ≤1 / 2(P2-P2×V2 / V1), and 3 Hz≤f≤250Hz.

[0031] The following needle types were tested using the above method. The test indicators included the following two points: 1. When dipped in ink, water was drawn into the housing, and the liquid was continuously drawn in until the liquid level rose to the position of the one-way valve 2 on the needle housing; 2. After the ink reservoir needle was removed from the ink, there was no ink droplet, ink spraying, or ink beading at the needle tip. When both of the above indicators were met, the integrated needle was deemed qualified. The test results are shown in Table 1 below, where ○ indicates qualified and × indicates unqualified.

[0032]

[0033] Table 1

[0034] Taking the 1203R ink reservoir needle as an example, assuming the internal pressure increases instantaneously, i.e., without considering pressure loss at the nozzle or air valve. With the sheath retracted, the internal volume of the shell is V1 (1.371 cm³), and the internal pressure is P1; with the sheath extended, the internal volume of the shell is V2 (1.268 cm³), and the internal pressure is P2. According to the law of state in physics, when the ambient temperature remains constant, the pressure of a gas is inversely proportional to its volume change, i.e., P1V1 = P2V2. Based on the formula, P2 = 120.6 kPa, meaning the internal pressure increase ΔP = 8.2 kPa. Considering other factors and ensuring product reliability, the air valve opening pressure should not exceed 2 / 3 of ΔP, i.e., the air valve opening pressure is Pk ≤ 106.7 kPa.

[0035] When the air valve opening pressure Pk=106Kpa and f=80Hz (this frequency is commonly used in tattooing), the relationship between the size of the needle tip gap area and the above phenomenon is tested. When the needle tip gap area AA exceeds 7.2mm... 2 At this time, the liquid intake speed inside the cavity is slow, and ink dripping occurs at the needle tip after the needle tip is separated from the liquid.

[0036] When the air valve opens at a pressure Pk = 106 kPa and the needle nozzle gap area A is 4.12 mm², 2 When (1223F), the relationship between the test frequency f≤2Hz and the above phenomenon is as follows: when f=2Hz, the ink absorption phenomenon becomes slow, and a water droplet slowly forms at the nozzle and drips down; when f=1Hz, the ink absorption phenomenon is extremely slow and cannot achieve the effect of ink storage. Example

[0037] like Figure 5 As shown, the tattoo device includes a grip 17, a drive unit installed in the grip, and an integrated tattoo needle. The grip 17 is cylindrical. The drive unit includes a drive motor 18 installed in the grip, an eccentric wheel 19 fixed on the drive motor, a follower wheel 20 sleeved on the eccentric wheel 19 and rotatably connected to the eccentric wheel 19, a flexible transmission steel wire 21 connected between the follower wheel 20 and the integrated tattoo needle, a power rod 9 connected to the front end of the transmission steel wire 21, and a counterweight wheel 23 coaxially arranged with the eccentric wheel 19 and used for balancing. When the drive motor 18 rotates, the eccentric wheel 19 drives the follower wheel 20 to reciprocate, which in turn drives the transmission steel wire 21 to reciprocate, and finally drives the integrated tattoo needle to reciprocate.

[0038] Specifically:

[0039] One-piece tattoo needle is like Figure 1-4 The large-capacity tattoo needle shown includes: a needle housing 1, a back cover 6, a needle wire 3, a transmission unit, a one-way valve 2, and a spring sleeve 5.

[0040] The needle housing 1 has a pointed nozzle 12 at its front end, with an ink storage cavity 13 formed in its middle and a central opening 11 on its circumferential surface. Its rear end is open. A rear cover 6 is placed over the open rear end of the needle housing 1. The needle wire 3 is installed inside the needle housing 1 and can extend from the nozzle 12. The rear end of the transmission unit passes through the rear cover 6, and its front end is fixedly connected to the needle wire 3. The drive motor 18 drives the transmission unit to reciprocate, thereby driving the needle wire 3 to reciprocate to complete the puncture action. A one-way valve 2 is located on the central opening 11; it is a silicone one-way valve. A spring sleeve 5 is fitted onto the transmission unit or the needle wire 3 and is sealed against the inner wall of the needle housing 1. The sleeve 5 is made of silicone. Its upper end is sealed on the end of the rear cover 6 located inside the needle shell 1, and its lower end is sealed on the transmission part. The transmission part includes a transmission rod 4 connected between the drive motor 18 and the needle wire 3. The front end of the transmission steel wire 21 is fixedly connected to the rear end of the transmission rod 4. The middle section of the transmission rod 4 is in the shape of a quadrangular prism. The rear cover 6 is provided with a quadrangular prism-shaped square hole 15 that matches the middle section of the transmission rod 4. A first sealing ring 16 is formed below the middle section of the transmission rod 4. The first sealing ring 16 is in the shape of a frustum with a thicker front side and a thinner rear side. The lower end of the spring sleeve 5 is sealed on the first sealing ring 16.

[0041] During tattooing, the drive motor 18 is activated, and the needle 3 is driven by the transmission unit to extend from the nozzle 12. At the same time, the spring sleeve 5 descends and squeezes the air in the ink storage chamber 13, causing the air to be discharged through the one-way valve 2, creating a negative pressure in the ink storage chamber 13. When the transmission rod 4 drives the needle 3 back into the ink storage chamber 13, the one-way valve 2 closes, and the gap between the needle 3 and the nozzle 12 is partially sealed by ink, keeping the ink from flowing out while allowing air to be replenished. When ink needs to be drawn into the ink storage chamber 13, the nozzle 12 is placed into the ink container 7. When the needle 3 retracts into the ink storage chamber 13, the ink 8 in the container 7 is drawn into the ink storage chamber 13 due to the negative pressure. The needle 3 completes the ink drawing process after reciprocating multiple times.

[0042] The middle section of the transmission rod 4 is prism-shaped, and the rear cover 6 has a square hole 15 in the shape of a prism matching the middle section of the transmission rod 4; the front end has a front mounting hole 24, and the grip 17 has a middle mounting hole 22 communicating with the front mounting hole 24, located behind the front mounting hole 24. The drive motor is installed in the grip 17 and behind the middle mounting hole 22. The rear end of the tattoo needle and the power rod 9 pass through the middle mounting hole 22. The power rod 9 has a spherical guide head 14. The center of the rear end face of the transmission rod 4 has a recessed and arc-shaped guide surface. The guide head 14 presses against the guide surface. The rear cover is fixedly installed in the front mounting hole 24. The head 14 is located inside the central mounting hole 22 and is clearance-fitted with the central mounting hole 22, so that when the guide head 14 pushes the guide surface at any angle, it is pressed on the center position of the guide surface, that is, on the axis of the transmission rod 4. The drive motor drives the power rod 9 to reciprocate. When the power rod 9 moves forward and pushes the transmission rod 4 forward, it drives the needle wire 3 to extend out of the mouth of the needle shell 1. At the same time, the spring sleeve 5 is stretched. When the power rod 9 moves backward, the spring sleeve 5 retracts. Since the front end of the spring sleeve 5 is tightly fitted on the first sealing ring 16 of the transmission rod 4, the retraction of the spring sleeve 5 will pull the transmission rod 3 back, that is, pull the needle wire 3 back into the needle shell 1. This cycle repeats.
