Description

Dual-purpose electromagnetic pen

Technical Field

The utility model relates to the technical field of electromagnetic pens, in particular to a dual-purpose electromagnetic pen.

Background

With the advent of the digital age, stylus technology has played an important role in the digital painting industry. In this field, electromagnetic pens (EMR handwriting pens) and active capacitance pens are two common technologies.

The electromagnetic pen (EMR handwriting pen) has higher technical threshold, adopts the electromagnetic induction principle, and an electromagnetic field emitted by an electromagnetic induction module (high-precision antenna board, MCU and the like) integrated in a digital board and a digital screen can be communicated with the pen by a signal with clearest and no interference, and has better stability (the interference of magnetic field environments such as a magnet and the like is avoided). The problems that the battery of the active capacitance pen fails or electrostatic interference causes drift, touch break and ink leakage to influence the use of the pen are avoided. The active capacitance pen has a lower technical threshold, is based on the pen technology of a touch screen, is used for finger touch control with low accuracy requirement, has a lower starting point, is difficult to stack grid density, has low accuracy and linear performance, and is simple to write and draw.

The active capacitance pen needs to be internally provided with a battery, the service life is limited, the active capacitance pen cannot be used when the power of an outgoing painting is off, and the service life is also longer than that of an electromagnetic pen due to the limitation of cyclic charging; and the capacitance pen is communicated with the panel through Bluetooth, the panel is fast in power consumption by continuous drawing, and the panel full power can be continuously drawn for about 3 hours. The electromagnetic pen is not provided with a built-in battery, does not need to be charged, can be used for drawing, is convenient to draw when going out, and has no problem for several years. In addition, when the capacitance pen writes, foreign matters, water stains and sweat on the screen, static electricity is generated by charging equipment, handwriting precision is disturbed by static electricity on hands and bodies of clothes, and abnormal phenomena such as ink leakage, shaking and drifting are generated. The electromagnetic pen (EMR handwriting pen) only has interference when being close to the magnet, and other aspects can write normally.

In some conferences and classrooms, electronic equipment with a large touch screen is used, files such as PPT are displayed through the electronic equipment, and some whiteboards, blackboards and the like are used for writing and displaying sometimes. Therefore, the user needs to use both the chalk and the electromagnetic pen. When a user actually uses, carrying 2 pens is inconvenient, and one pen cannot meet 2 writing requirements of the user.

In order to solve the technical problems, the embodiment of the utility model provides a dual-purpose electromagnetic pen, which comprises a pen container, wherein the front end of the pen container is provided with a magnetic ring assembly, the electromagnetic pen further comprises a pressing cylinder and a pen core, the pen container is sleeved outside the pressing cylinder, the pen core is inserted in the pressing cylinder, the front end of the pressing cylinder is provided with a clamping part, the tail end of the pen container is internally provided with a rear limiting part, the periphery of the pressing cylinder is provided with a limiting buckle correspondingly matched with the rear limiting part, the pen container is internally provided with a return spring, and the return spring applies backward return force to the pressing cylinder.

Further, the clamping part consists of a plurality of claw sheets, and the outer sides of the front ends of the claw sheets are convexly provided with extrusion parts.

Further, a front limiting part for limiting the front limit of the limiting buckle is arranged in the pen container.

Further, one end of the return spring acts on the front limiting part, and the other end acts on the limiting buckle.

Further, the pen refill is a chalk refill.

Further, the rear limit part and/or the limit buckle are/is annular.

Further, the magnetic ring assembly consists of a magnetic ring and a coil sleeved outside the magnetic ring.

The beneficial effects of the utility model are as follows: the pen refill is simple in structure, convenient to replace and convenient to carry, and can realize the conventional writing and electromagnetic pen writing functions.
