Description

电磁感应开关
技术领域
本发明涉及一种电磁感应开关。
背景技术
一般的无线简报笔均采用电池供电，并在电池与工作电路间设计一电源开关，以通过对电源开关的操作来控制简报笔的工作，可在简报笔不被使用时关闭电源，节省电池电量。
但是采用电源开关控制简报笔的工作，在使用时会造成操作不便，例如使用时必须手动打开开关，操作不方便；且使用后如果忘记关闭电源开关将会造成电池电量浪费。
发明内容
鉴于以上内容，有必要提供一种电磁感应开关，根据简报笔的使用状态自动对电源是否开通进行调整。
一种电磁感应开关，其包括一螺线环、一悬置于所述螺线环中的磁体、一整流电路及一延时开关，所述螺线环连接于所述整流电路的两整流引脚之间，所述整流电路的两输出引脚分别与所述延时开关的继电器的两引脚对应连接，所述延时开关的开关引脚之一与一工作电路连接，所述延时开关另一开关引脚通过一电池与所述工作电路连接。
上述电磁感应开关利用磁体在螺线环中运动产生感应电动势，通过整流电路后使所述延时开关的继电器通电，从而使所述延时开关闭合，接通电池与所述工作电路，在简报笔停止使用后所述磁体停止运动，不再产生感应电动势，所述延时开关因其中的继电器断电而自动打开，将所述电池与所述工作电路断开，从而简报笔的使用更加方便，且不会因忘记关开关而浪费电池电量。
附图说明
下面结合附图及较佳实施方式对本发明作进一步详细描述：
图1是本发明电磁感应开关较佳实施方式的电路图。
具体实施方式
参考图1，一种电磁感应开关10，用于控制无线简报笔电源，其包括一螺线环L、一悬置于所述螺线环L中的磁体M、一单向桥式整流电路BD及一延时开关RS，所述螺线环L连接于所述单向桥式整流电路BD的整流引脚1和2之间，所述单向桥式整流电路BD的输出引脚3和4分别与所述延时开关RS继电器的引脚1’和2’对应连接，所述延时开关RS的开关引脚3’与一无线简报笔的工作电路20连接，所述延时开关RS的开关引脚4’通过一电池BT与所述工作电路20连接。
所述电磁感应开关10还包括一延时电容C，所述延时电容C连接于所述延时开关RS的继电器引脚1和2之间。
简报笔被使用时，其产生的晃动使所述磁体M在所述螺线环L中移动，从而切割磁感线产生一感应电动势，所述感应电动势经所述单向桥式整流电路BD整流后使所述延时开关RS的继电器通电，从而使所述延时开关RS中的开关部闭合，将所述电池BT接入所述工作电路20中。其间简报笔可能有短时间停顿，此时所述延时电容C放电，使所述延时开关RS继续维持闭合状态，维持简报笔工作。
当简报笔停止使用后，所述磁体M处于静止状态，所述感应电动势消失，在延时电容C放电完毕后所述延时开关RS的开关部断开，从而将所述电池BT与所述工作电路20断开。
所述电磁感应开关10利用简报笔使用时产生的晃动使磁体M在螺线环L中运动产生电能，从而控制所述延时开关RS闭合，接通电池BT与所述工作电路20，在简报笔停止使用后所述延时开关RS自动断开，从而将所述电池BT与所述工作电路20断开。
