Abstract

The invention discloses mahjong and a patch. The mahjong comprises a shell, the shell comprises a first face and a second face which are oppositely arranged, the mahjong further comprises at least one coil arranged in the shell and a diode connected with the coil in series, a first filling piece made of soft magnetic materials is arranged in the shell, a second filling piece made of soft magnetic materials is arranged in the shell, and the radial plane of the coil is parallel to the first surface. According to the mahjong and the patch, the coil and the diode connected with the coil in series are arranged, so that when the mahjong is in an alternating magnetic field, the coil can generate a directional current, a stable magnetic field is generated, the magnetic pole is fixed, the shell is made of a soft magnetic material, under the amplification effect of the soft magnetic material, the mahjong can meet the requirement of magnetic control, the mahjong can be shuffled and carried in the mahjong machine, after shuffling is finished and the mahjong leaves the alternating electromagnetic field, the current in the coil returns to zero, and the mahjong does not have magnetism any more.

Description

technical field [0001] The invention relates to the technical field of magnetic mahjong, in particular to a mahjong and a patch. Background technique [0002] The mahjong used in the traditional mahjong machine is to add a pre-magnetized permanent magnet to the mahjong tiles as a mark for the front and back of the mahjong tiles, and is also used for the grasping of the mahjong machine secondary selection mechanism. [0003] However, such mahjong tiles have strong magnetism during use, which is not conducive to use, and will also cause a series of problems such as magnetized watches. Contents of the invention [0004] In view of the problems existing in the prior art, the present invention proposes a method in which during the operation of the mahjong machine, the mahjong tiles can be generated from the magnetic characteristics of the previous permanent magnet mahjong tiles through the induced magnetic field applied by the outside, but after the induced magnetic field disap...
