Detailed ways

Below in conjunction with accompanying drawing, the technical scheme of the utility model is described further.

As shown in Figure 1, it includes a power torch module (1), a conversion circuit device box (2), an inflator outer cylinder (3), an inflator rod (4), an inflator handle (5) and an electric energy output interface (6) . Pushing and pulling the inflator rod will vibrate the circular fan-shaped piezoelectric ceramic sheet in the generator module connected to the top of the pump outer cylinder to generate unstable electric energy, and then convert the generated unstable electric energy through the conversion circuit in the conversion circuit device box Stable electric energy is used for lithium battery energy storage, and the stored energy can be output through the electric energy output interface.

As shown in Fig. 2, the torch module includes an outer cylinder body (7) of the torch module, insulating holes (8), multiple sets of piezoelectric generating units (9), and a torch module base (10). Multiple sets of piezoelectric generating units are placed inside the outer cylinder of the generator module, and interact with the inflator rod to generate electric energy. The insulating hole runs through the outer cylinder wall of the flashlight module, and its function is to lead out the electrode wires, and can avoid the problem of short circuit caused by the contact of the positive and negative poles of the connected ring fan-shaped piezoelectric ceramic sheet. Threads are processed on the base of the flashlight module to facilitate the installation and removal of the flashlight module.

As shown in Fig. 3, a group of piezoelectric generating units includes an insulating ring (11), a copper ring (12), a ring sector piezoelectric ceramic sheet (13) and a copper base (14). According to the principle of piezoelectric cantilever beam power generation, the inside of the copper base is processed into a sector with the same angular width as the ring sector piezoelectric ceramic sheet, but the radial length of the copper base is longer than that of the ring sector piezoelectric ceramic sheet. In this way, damage to the ring-sector piezoelectric ceramic sheet due to the direct contact between the ring-shaped protrusion on the inflator rod and the ring-sector piezoelectric ceramic sheet is avoided. Ring fan-shaped piezoelectric ceramic sheets are pasted on the upper and lower sides of the copper base. The radius of the insulating ring is slightly larger than that of the copper ring to prevent the copper ring from contacting the inner wall of the outer barrel of the flashlight module. The wires connecting the positive and negative poles of the ring fan-shaped piezoelectric ceramic sheet are connected with the conversion circuit through the insulating hole.

As shown in Figure 4, several ring-shaped protrusions (15) of moderate size are provided on the inflating rod. When the inflator rod is pushed up and down, the ring-shaped protrusion will stir the copper base, causing the copper base to vibrate, so that the ring fan-shaped piezoelectric ceramic sheet on the copper base vibrates to generate electricity.
