Problems solved by technology

[0003] However, the application of piezoelectric ceramics on chargers is rare in the prior art
Existing chargers generally need to be connected to a power supply to charge electrical appliances, which consumes existing natural energy, such as coal power or nuclear power, which is not only inconvenient to operate, but also not environmentally friendly
[0004] In summary, the existing charger technology obviously has inconvenience and defects in actual use, so it is necessary to improve it

Abstract

The invention relates to the technical field of piezoelectricity, in particular to a piezoelectric charger which is used for charging a to-be-charged object and comprises a shell, a piezoelectric assembly and a power source, the piezoelectric assembly is arranged in the shell and comprises at least one piezoelectric ceramic piece, a positive electrode piece and a negative electrode piece, and the positive electrode piece and the negative electrode piece are arranged at the upper end and the lower end of the piezoelectric ceramic piece respectively. The positive wire and the negative wire are respectively led out by the positive electrode plate and the negative electrode plate; the pressing assembly comprises a button cover and a pressurization force application piece, the button cover is provided with a containing space, the pressurization force application piece is in a rod shape, the tail end of the pressurization force application piece faces the upper end of the piezoelectric assembly, and the head end of the pressurization force application piece extends into the containing space; the button cover covers the head end of the shell; the button cover is pressed to apply force to the pressurizing and force applying piece, the pressurizing and force applying piece presses the piezoelectric assembly after being stressed, and the piezoelectric assembly generates current after being stressed. Therefore, the piezoelectric charger provided by the invention not only is convenient to operate, but also is environment-friendly.

Description

technical field [0001] The invention relates to the field of piezoelectric technology, in particular to a piezoelectric charger. Background technique [0002] Piezoelectric ceramics are special ceramic materials widely used in the fields of ultrasound, electroacoustics, communications, ranging, underwater acoustic detection, sensing, etc. The piezoelectric effect is that when the piezoelectric material is under pressure, the piezoelectric material will deform , thereby generating electricity across the two electrodes of the material. Conversely, when a voltage is applied to the two electrodes, the piezoelectric ceramic will deform, which is called the inverse piezoelectric effect. [0003] However, the application of piezoelectric ceramics to chargers is rare in the prior art. Existing chargers generally need to be connected to a power supply to charge electrical appliances, which consumes existing natural energy, such as coal power or nuclear power, which is not only inco...
