Description

Solar Torch Device

technical field

The utility model relates to a solar flashlight device, which belongs to the field of lighting equipment.

Background technique

With the improvement of people's life taste, household appliances tend to be more and more green energy and green life. Facing the shortage of resources, more attention is paid to saving resources. Traditional flashlights have disposable dry batteries, which cannot be recycled and cause waste of resources. If they are not handled properly, they will cause serious environmental pollution. One dry battery can pollute 1 ton of water. With the development of science and technology, modern rechargeable flashlights have been widely used, but the charging of the flashlight can only be connected to the household AC power supply, which is heavily dependent on the household power supply. The use is restricted by the power supply, the power load is heavy, and resources are tight. A kind of clean energy has attracted more and more people's attention. It has the advantages of being universal, harmless, huge and long-lasting. It can effectively relieve the pressure on electricity and save energy.

Utility model content

The technical problem to be solved by the utility model is to provide a new type of solar flashlight device, which is mainly composed of a solar panel, a cylinder, a battery, a lampshade, a lamp bead, a switch, a hinge, and a diode.

When the utility model is in use: the positive pole of the lamp bead installed in the lampshade is connected with the switch at the front end of the cylinder body through a wire, the switch at the front end of the cylinder body is connected with the positive pole of the battery through a wire, and the negative pole of the lamp bead in the lampshade is directly connected with the battery through a wire The solar panels are connected by hinges, the positive pole of the solar panel is connected to the anode of the diode through a wire, the cathode of the diode is connected to the positive pole of the battery, and the negative pole of the solar panel can be directly connected to the negative pole of the battery through a wire; When the solar flashlight is not charging, the solar panel can be folded on the barrel through the hinge; when charging, the solar panel can be unfolded as needed, and the external solar panel can also be extended through the hinge to enhance the charging of the battery by the solar panel.

The lamp bead is a high-performance light bulb capable of long-distance lighting.

The switch is a toggle switch, which is convenient for the flashlight to be turned on and off.

The hinge can connect and expand the solar battery panel, and an interface is provided inside the hinge to connect the positive and negative poles of the solar battery panel respectively.

Each of the solar panels is connected in parallel, and a DC-DC control circuit is not needed when expanding the solar panels; the parallel connection of the solar panels will increase the current, so a current-limiting resistor is needed between the battery and the solar panels.

The beneficial effects of the utility model are: the solar flashlight device of the utility model includes a square cylinder, lamp beads in the lampshade, a storage battery built in the square cylinder, and a switch is installed at the front end of the cylinder, which is convenient for controlling the communication of the battery when holding the flashlight. cut off, so that the battery forms a loop with the lamp beads in the lampshade through the switch. The shell of the cylinder is wrapped with solar panels. During the day, the solar panels can be unfolded according to needs. The solar panels are connected by hinges, which not only facilitates the folding of the solar panels, but also enables the expansion of the external solar panels and enhances the The solar panels charge the battery. The novel solar panel has the advantages of simple structure, energy saving, high reliability, low cost and the like.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.
