Technical Field
[0001] The utility model relates to a tattoo pen, in particular to a tattoo pen with a direct-drive motor. Background Art
[0002] There are numerous motor-driven tattoo pens on the market, but none offer adjustable needle hardness to suit the artist's needs. This is similar to the rebound force generated by a coil tattoo machine's needle when it encounters resistance. However, coil tattoo machines are heavier and less convenient to use than motor tattoo pens. Because coil tattoo machines operate differently from motor tattoo pens, motor tattoo pens produce a more direct and stiff needle. Therefore, tattoo artists desire a motor tattoo pen with the same resilience as a coil tattoo machine. After a period of experimentation, we have finally developed this direct-drive motor tattoo pen, which allows for adjustable needle hardness. Utility Model Content

DETAILED DESCRIPTION
[0024] The present invention will be further described below in conjunction with the accompanying drawings.
[0025] Example 1:
[0026] like Figures 1 to 5 As shown, a direct-drive motor tattoo pen comprises a sleeve 1, within which is housed a power unit that slides up and down. Atop the power unit is an elastic component for adjusting the hardness of the needle ejection. The elastic component comprises an adjustment ring 2, a limit slider 3, and an elastic member. The adjustment ring 2 abuts the top of the inner side of the sleeve 1, while the limit slider 3 is located below the adjustment ring 2. The adjustment ring 2 and the limit slider 3 are connected with an adjustable spacing, and the elastic member is located between the power unit and the limit slider 3. The resistance of the tattoo needle contacting the skin causes the power unit to slide upward along the sleeve 1. As the power unit slides upward, the elastic member limits its sliding distance within the sleeve 1, allowing the tattoo artist to freely adjust the hardness of the needle ejection during the tattooing process. The adjustable spacing between the adjustment ring 2 and the limit slider 3 allows the adjustment ring 2 to control the spacing between the limit slider 3 and the power unit, thereby controlling the distance the power unit moves within the sleeve 1 during use, thereby achieving different hardnesses of the needle ejection.
[0027] The power component includes a motor compartment 4, in which a motor 5 is provided, and slide rails 15 integrally provided with the motor compartment 4 are provided on both sides of the outer side surface of the motor compartment 4, and a slide groove 14 adapted to the slide rail 15 is provided on the inner side wall of the sleeve 1. The arrangement of the slide rail 15 and the slide groove 14 facilitates the motor compartment 4 to move up and down without circumferential rotation. The outer side surface of the limit slider 3 is provided with two slide rails 16 adapted to the slide groove 14, which facilitates the position of the limit slider 3 up and down in the sleeve 1. The bottom of the slide groove 14 is connected with the bottom of the sleeve 1, which facilitates the installation of the limit slider 3 and the motor compartment 4 into the sleeve 1. The slide groove 14 effectively prevents the limit slider 3 and the motor compartment 4 from circumferential rotation in the sleeve 1; the top of the slide groove 14 is located in the sleeve 1, that is, the top of the slide groove 14 is not connected with the top of the sleeve 1, so that the top of the slide groove 14 has a limiting effect.
[0028] An eccentric wheel 6 and a balance wheel 7 are provided on the output shaft of the motor 5 . The balance wheel 7 is fixed to the output shaft by fastening bolts. A connecting ring 8 is provided on the outside of the eccentric wheel 6 , and a guide rod 9 is provided below the connecting ring 8 .
[0029] The bottom of the sleeve 1 is equipped with a handle 10, and the top of the sleeve 1 is equipped with an adjustment sleeve 11 and a plug-in wireless power supply 12. The plug-in wireless power supply 12 is a power supply composed of a housing and a rechargeable battery. The adjustment sleeve 11 plugs into the top of the sleeve 1 and has a power port inside. The plug-in wireless power supply 12 plugs into the top of the adjustment sleeve 11. The outer side of the guide rod 9 is equipped with a transmission compartment 13. The upper side of the transmission compartment 13 is threadedly connected to the inner side of the sleeve 1, and the lower side of the transmission compartment 13 is threadedly connected to the inner side of the handle 10.
[0030] When the limit slider 3 abuts against the top of the slide groove 14, the distance between the limit slider 3 and the motor compartment 4 is the largest, the extrusion force on the elastic member is small, and the elastic force is small. When the tattoo pen is working, the tattoo needle encounters the resistance of the skin and drives the guide rod 9 and the motor compartment 4 to slide into the sleeve 1, and the sliding distance is long.
[0031] The elastic member includes a first magnet 17 and a second magnet 18. The first magnet 17 is embedded in the upper side of the motor housing 4, and the second magnet 18 is embedded in the lower side of the limit slider 3. The first and second magnets 17, 18 have the same poles facing each other. During operation, when the guide rod 9 drives the tattoo needle into contact with the skin and the tattoo needle encounters skin resistance, the guide rod 9 and the motor housing 4 slide together along the slide groove 14 via the slide rail 15 into the sleeve 1. Utilizing the principle that magnets with the same poles repel, the first magnet 17 at the top of the motor housing 4 and the second magnet 18 at the bottom of the limit slider 3 generate a repulsive force. By rotating the adjustment ring 2 to adjust the upper and lower positions of the limit slider 3, the distance between the first magnet 17 at the top of the motor housing 4 and the second magnet 18 at the bottom of the limit slider 3 changes, thereby varying the hardness of the tattoo pen during needle removal. The greater the distance between the first magnet 17 and the second magnet 18, the smaller the repulsive force, resulting in a softer needle removal. The smaller the distance between the first magnet 17 and the second magnet 18, the greater the repulsive force, resulting in a harder needle removal.
[0032] The connecting hole in the center of the adjusting ring 2 is provided with an internal thread, the top of the limiting slider 3 is provided with a connecting column, the outside of the connecting column is provided with an external thread, the connecting column and the connecting hole are connected by threads, and the threaded connection length between the connecting column and the connecting hole is adjusted by rotating the adjusting ring 2, thereby adjusting the distance between the adjusting ring 2 and the limiting slider 3, and adjusting the distance between the limiting slider 3 and the motor compartment 4, limiting the sliding distance of the motor compartment 4 in the sleeve 1, and obtaining different hardness of the needle.
[0033] Usage process:
[0034] 1. When the tattoo pen with direct drive motor 5 is performing tattooing, the guide rod 9 drives the tattoo needle to contact the skin. When the tattoo needle encounters resistance from the skin, the guide rod 9 and the motor compartment 4 will slide together into the sleeve 1 along the slide groove 14 through the slide rail 15.
[0035] 2. Using the principle that like poles of magnets repel each other, the No. 1 magnet 17 on the top of the motor compartment 4 and the No. 2 magnet 18 at the bottom of the limit slider 3 generate a repulsive force. By rotating the adjustment ring 2, you can adjust the distance between the No. 1 magnet 17 on the top of the motor compartment 4 and the No. 2 magnet 18 at the bottom of the limit slider 3 to change the hardness of the tattoo pen needle. The greater the distance between the No. 1 magnet 17 and the No. 2 magnet 18, the smaller the repulsive force and the softer the needle. The smaller the distance between the No. 1 magnet 17 and the No. 2 magnet 18, the greater the repulsive force and the harder the needle.
[0036] Example 2:
[0037] The second embodiment is basically the same as the first embodiment, the difference is that the elastic member, such as Figure 6-7 As shown, the elastic member includes a spring 19 or a spring 20, which is located between the motor housing 4 and the limit slider 3. The two ends of the spring 19 or spring 20 respectively abut the top of the motor housing 4 and the bottom of the limit slider 3. When the motor housing 4 moves into the sleeve 1, the spring 19 or spring 20 exerts an outward force on the motor housing 4, facilitating the adjustment of the needle ejection hardness.
[0038] The above is a preferred embodiment of the present invention. Those skilled in the art may make several modifications and improvements without departing from the principles of the present invention, and these modifications and improvements should also be considered as within the scope of protection of the present invention.
