Description

TECHNICAL FIELD The present invention relates to the technical field of tattooing, in particular to a tattooing device. BACKGROUND Tattoo needle is a special tool for tattoo operation, and its design and material are very important for the effect and safety of tattoo. The working principle of tattoo needle is to evenly puncture the epidermis at a high speed, and implant ink into the dermis under the epidermis. In this way, the human body will try to devour and eliminate foreign invaders when dealing with damaged white blood cells, and the pigment particles are small and easy to be swallowed and can be permanently fixed on the epidermis, forming patterns and characters of various pigment combinations, thus completing tattoos. In the tattooing needle of the prior art, the needle tip opening of the needle mouth is usually a smooth and flat surface, and the adsorption force between the ink and the needle mouth is not strong, so that when the needle is inserted back and forth from the needle mouth, it is easy to cause ink dripping, ink leakage, ink ejection and the like, which affects the tattooing effect and efficiency; in addition, during the tattooing process of the existing tattooing needle, the needle mouth is mostly inclined downwards, so that the ink flowing out of the needle mouth tends to pollute tattoo machine, and may even cause cross infection of diseases. See, e.g., US2022143378 A1 which discloses a needle module for a tattoo device includes a housing and a needle bundle. The housing comprises a first end for coupling to the tattoo device, a second end comprising a mouth, and a channel between the first and second ends. The needle bundle is moveably mounted in the channel of the housing and is reciprocally moveable in an axial direction between a retracted position and an extended position through the mouth. The mouth comprises at least two jaws. At least one of the jaws is flexible and flareable when radially biased by the needle bundle. See further US2013226211 A1 which provides a tattoo needle tip equipped with a capillary ink reservoir, a tattoo tube having the said tattoo needle tip, and an assembly of the said tattoo needle tip and a tattoo needle. The tattoo needle tip equipped with a capillary ink reservoir comprises a needle tip body. A tattoo needle passage is provided inside the needle tip body. A needle tip opening is provided at one end of the needle tip body, and the needle tip opening and the tattoo needle passage are connected. The needle tip body is provided with at least one ink reservoir for containing and storing ink. The ink reservoir is provided with at least one ink chamber with capillary action. At least one ink guiding passage connects the capillary ink chamber with the needle tip opening. The tattoo needle tip equipped with an ink reservoir utilizes capillary action to store ink in the ink reservoir, thereby having a big capacity of ink storage and preventing ink leakage from easily occurring. See finally US2019217072 A1 which discloses a needle assembly for a liquid applicator includes a housing comprising a tubular longitudinal channel and a guide/inner surface. The channel comprises an upper open end and a lower open end. Liquid storage grooves for storing liquid by capillary action extend generally transversely in the guide/inner surface above the lower open end. A needle bundle is mounted in the housing. The needle bundle comprise one or more needles longitudinally reciprocally movable in the channel and being biased against the guide surface, or towards the inner surface, across the grooves such that, during longitudinal reciprocal movement of the needle bundle, the needle bundle maintains contact with the guide surface and the liquid stored in the grooves, or maintains a capillary gap between the needle bundle and the inner surface, for drawing the liquid out of the grooves by capillary action. Therefore, it is necessary to propose a new tattoo needle. When ink is stored in the needle mouth, the adsorption force between the ink and the needle mouth is greater, thus effectively reducing the occurrence of ink dripping, ink leakage, ink ejection and the like in the tattoo process; moreover, the novel tattooing needle can recycle the ink flowing out of the needle mouth in case of ink leakage during tattooing, so as to avoid ink pollution or cross infection of diseases.
