Self-powered PPT pen

Abstract

The invention discloses a self-powered PPT pen, which comprises a PZT piezoelectric ceramic piece piezoelectric conversion module, a piezoelectric power generation electric energy rectification and collection module, a SkyclorPPT pen circuit module and a USB receiving module, and is characterized in that the signal output end of the PZT piezoelectric ceramic piece piezoelectric conversion module is in electric signal connection with the signal input end of the piezoelectric power generation electric energy rectification and collection module; the signal output end of the piezoelectric power generation electric energy rectification and collection module is in electric signal connection with the signal input end of the SkylotorPPT pen circuit module, and the signal output end of the SkylotorPPT pen circuit module is in electric signal connection with the signal input end of the USB receiving module. The PZT piezoelectric ceramic piece piezoelectric conversion module is used for converting input mechanical energy into electric energy to be output, generated irregular electric energy can be converted into stable direct current through the piezoelectric power generation electric energy rectifying and collecting module, the stable direct current is well matched with a PPT office pen, and therefore power supply for the page turning pen is achieved.

Description

technical field [0001] The invention relates to the technical field of PPT pens, in particular to a self-powered PPT pen. Background technique [0002] In recent years, with the popularization of intelligent classrooms and conferences, the number of users of page presenters has become wider and wider, and the sales of page presenters have shown explosive growth. As an accessory product of the page presenter, the consumption of dry batteries is also huge. If the dry batteries are not properly disposed of, they will pollute the environment. After a certain storage period, the self-discharge of ordinary dry batteries will increase, and the performance of the batteries will decrease. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, an object of the present invention is to propose a self-powered PPT pen, realize self-power supply, and get rid of the dependence ...

Problems solved by technology

As an accessory product of the page presenter, the consumption of dry batteries is also huge. If the dry batteries are discarded, they will pollute the environment if they are not disposed of properly. Moreover, after a certain storage period, the self-discharge of ordinary dry batteries will increase, and the performance of the batteries will decrease.
