Adjustable power supply based on button cell

Abstract

The invention discloses an adjustable power supply based on a button cell. The adjustable power supply comprises a box body. The adjustable power supply is advantageous in that: the box body is a cylindrical box body of which the bottom is provided with an internal threaded hole and the upper part is provided with a limiting hole; a convex copper head, a copper spring, a copper baffle plate, a button battery and a copper bolt are arranged in the box body; the top end of the copper spring is welded with the bottom end of the convex copper head; the top end of the copper baffle is welded with the bottom end of the copper spring; and the diameter of the screw rod of the copper bolt is matched with the aperture of the inner threaded hole in the bottom of the box body, and the screw rod of the copper bolt can be fixed to the bottom of the box body by twisting the screw head of the copper bolt. By adjusting the length of the copper spring and changing the number of the button cells, six different types of power supplies I5, I7, II5, II7, III5 and III7 can be adjusted.

Description

technical field [0001] The invention relates to the field of application expansion of button batteries, in particular to an adjustable power supply based on button batteries. Background technique [0002] In the daily life of the family, the 5th and 7th batteries are often used as the power supply of flashlights, electronic clocks, children's toys, remote controls and other equipment, but the conventional 5th and 7th batteries have the following disadvantages in the process of use: [0003] 1. Ordinary alkaline zinc-manganese batteries are not rechargeable, so they must be discarded after use, resulting in waste of resources; [0004] 2. Rechargeable nickel-cadmium (Ni-Cd) batteries contain heavy metal cadmium, which pollutes the environment; [0005] 3. The heights of the 5th and 7th batteries are different, and they cannot be used universally. Different types of batteries need to be purchased for different electrical equipment, which is inconvenient to use. [0006] Butt...

Problems solved by technology

[0003] 1. Ordinary alkaline zinc-manganese batteries are not rechargeable, so they must be discarded after use, resulting in waste of resources;

[0004] 2. Rechargeable nickel-cadmium (Ni-Cd) batteries contain heavy metal cadmium, which pollutes the environment;

[0005] 3. The heights of the 5th and 7th batteries are different and cannot be used universally. Different types of batteries need to be purchased for different electrical equipment, which is inconvenient to use

However, the size of the button battery is too small to be applied to the working scene of the 5th and 7th batteries
