Description

Technical Field

[0001] This utility model relates to the field of tattoo equipment, and in particular to a tattoo pen with a replaceable battery. Background Technology

[0002] A tattoo pen is a tattooing tool that uses an internal motor to drive a oscillating disc. The oscillating disc then pushes a rod to extend and retract, which in turn pushes the needle inside the tattoo needle tip to extend and retract. When the tattoo pen tip extends and retracts, the ink inside the tattoo needle tip is inserted into the skin to form a permanent pattern.

[0003] In most common tattoo pens, the motor is powered by a power cord with a plug. While these pens can work for extended periods, the power cord can interfere with the tattooing process. Some tattoo pens have a built-in battery that powers the internal motor, but these pens cannot work for long periods and require regular battery charging.

[0004] Therefore, designing a tattoo pen with easily replaceable batteries is a problem that the industry urgently needs to solve. Utility Model Content

[0005] The purpose of this invention is to provide a tattoo pen with a replaceable battery. This invention has the advantage of making battery replacement convenient.

[0006] The technical solution of this utility model is as follows: A replaceable battery tattoo pen includes a cylindrical tattoo pen body; a battery compartment is detachably connected to the top of the tattoo pen body, the battery compartment being cylindrical with the same diameter as the tattoo pen body; one side of the battery compartment has an opening for battery insertion and removal, and both sides of the battery compartment corresponding to the opening have concave side edges, the bottom ends of both side edges being connected to horizontally outwardly oriented ball plungers; an upwardly extending baffle is connected to the edge of the top of the tattoo pen body, the baffle being semi-circular in shape, and both sides of the baffle covering the two side edges and fitting over the opening, the baffle having vertical grooves corresponding to the ball plungers on both sides, the bottom ends of the grooves having positioning holes; the top surface of the tattoo pen body and the bottom surface of the battery compartment are both planar; an upwardly protruding conductive metal foot is connected to the top surface of the tattoo pen body, the conductive metal foot being located inside the baffle; a conductive plug is provided on the bottom surface of the battery compartment corresponding to the conductive metal foot.

[0007] In the aforementioned tattoo pen with a replaceable battery, the top of the side is connected to a limiting block that mates with a sliding groove, and the limiting block is located directly above the ball-head plunger.

[0008] In the aforementioned replaceable battery tattoo pen, multiple horizontally arranged elastic clips are connected to the battery compartment at positions corresponding to the opening, and all the elastic clips are distributed at intervals in the vertical direction; conductive springs and conductive sheets are respectively connected to the upper and lower ends of the battery compartment corresponding to the opening.

[0009] In the aforementioned tattoo pen with a replaceable battery, the open elastic clip is detachably fixed inside the battery compartment by screws.

[0010] In the aforementioned tattoo pen with a replaceable battery, one side of the battery compartment is connected to an outwardly protruding bump, on which a display screen and control buttons are connected.

[0011] Compared with the prior art, this utility model has an opening on one side of the cylindrical battery compartment for battery insertion and removal, and concave side edges on both sides of the opening. Each side edge has a horizontally outward-facing ball-head plunger connected to its bottom end. A semi-circular, upward-extending baffle is connected to one side of the top of the cylindrical tattoo pen body. The baffle has grooves on both sides, with positioning holes at the bottom of the grooves. This allows the battery compartment to slide into the baffle, meaning the ball-head plungers at the bottom of the two side edges can slide along the grooves and engage in the positioning holes. The baffle covers the two side edges and the opening, achieving a detachable connection between the tattoo pen body and the cylindrical battery compartment. During use, the opening on one side of the battery compartment is covered, preventing electric shock and short circuits. When replacing the battery, simply slide the battery compartment upwards along the baffle and pull it out through the opening to replace the battery, making the operation convenient.

[0012] The tattoo pen body has an upward-protruding conductive metal foot connected to the top surface of the body. The conductive metal foot is protected by the guard edge and is not easily damaged by impact. The battery compartment has a conductive plug at the corresponding part of the conductive metal foot on the bottom surface of the battery compartment, which makes the conductive connection between the battery compartment and the tattoo pen body more convenient. The combination of two ball plungers and two sliding grooves allows the conductive plug to be better inserted and connected with the conductive metal foot when the battery compartment slides down.

[0013] In addition, the top of the side of this utility model is connected to a limiting block that cooperates with the slide groove. The limiting block is located directly above the ball plunger. When the battery compartment is inserted into the top of the tattoo pen body, the limiting block can be locked in the top of the slide groove. At the same time, the ball plunger cooperates with the positioning hole groove at the bottom of the slide groove, which makes the battery compartment more stably inserted into the stop.

[0014] Multiple horizontally arranged elastic clips are connected inside the opening, and all the elastic clips are distributed vertically at intervals. The multiple elastic clips can stably hold the cylindrical battery. The elastic clips are made of open-shaped spring plates. The battery can be installed by pressing it in through the opening, and removed by gripping the battery through the gap between adjacent elastic clips and pulling it outward. The installation and removal operations are relatively convenient. Conductive springs and conductive plates are connected to the upper and lower ends of the battery compartment corresponding to the opening. After the battery is installed in the battery compartment, both ends of the battery can contact the conductive springs and conductive plates respectively to provide power.

[0015] The open-end elastic clip is detachably connected to the battery compartment using screws, which facilitates the disassembly and replacement of the open-end elastic clip and improves overall durability.

[0016] The battery compartment has an outward protrusion on one side, which allows users to push the battery compartment up and down relative to the edge, making it easy to install and remove the battery compartment. The protrusion is equipped with a display screen and control buttons, which allows users to observe and control the power supply status.

[0017] Therefore, this utility model not only enables battery replacement, but also has the advantage of being relatively convenient to replace batteries. Attached Figure Description
