Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the following embodiments and drawings.
As shown in fig. 1 to 3, the magnetic powder writing pen includes a hollow pen tube 10, a front cap 20, a pen cap 30, magnetic powder 40 and a magnetic plate 50; the bottom of the hollow pen tube 10 is provided with a magnetic powder outlet 12, and the top is provided with a magnetic powder inlet 14; the front cover 20 is detachably mounted at the magnetic powder outlet 12; the pen cap 30 is detachably mounted at the magnetic powder inlet 14; the pen cap 30 comprises an electromagnet 32, a battery 34 and a control switch 36; the electromagnet 32 and the battery 34 are installed inside the pen cap 30, the control switch 36 is installed outside the pen cap 30, and the control switch 36 is located between the electric connection loops of the electromagnet 32 and the battery 34, so that the connection and disconnection between the electromagnet 32 and the battery 34 can be controlled; the magnetic powder 40 is filled in the hollow pen tube 10 and can be written on the magnetic plate 50 through the magnetic powder outlet 12.
As shown in fig. 1 to 3, the magnetic force generated by the electromagnet 32 is greater than the magnetic force generated by the magnetic plate 50.
As shown in fig. 1 to 3, the aperture of the magnetic powder outlet 12 is smaller than that of the magnetic powder inlet 14.
As shown in fig. 1 to 3, the magnetic powder outlet 12 of the environment-friendly magnetic powder writing pen has an inverted cone shape.
