Hourglass timing circuit switch device

Abstract

The invention provides an opening and closing device for an hourglass timing circuit, which includes a transparent shell, a base, a middle passage, and an electrical connection seat; the transparent shell is filled with metal fine sand; the middle of the base is designed with a metal block, and the base A metal layer is wrapped in the circumferential direction, and the metal layer is connected to the middle channel through the middle line; the base is placed above the electrical connection seat, and the electrical connection seat includes an intermediate connection block and an annular connection block made of metal materials, The intermediate connection block is located in the middle above the electrical connection seat, and the size of the annular connection block matches the metal layer; the intermediate connection block is in close contact with the metal block, and the annular connection block is in close contact with the metal layer. The metal layers are in tight contact. The device can not only be used as an hourglass alone, but also can directly visualize the time through the hourglass structure, and can switch circuits at regular intervals.

Description

[0001] Technical field [0002] The invention belongs to the technical field of timing electrical equipment, and in particular relates to an opening and closing device for an hourglass timing circuit. Background technique [0003] An hourglass, also called a sand clock, is a device for measuring time. The hourglass consists of two transparent chambers and a narrow connecting pipe. The two transparent chambers are filled with fine sand, and the time required for the fine sand to flow from the upper transparent chamber through the narrow pipe into the bottom chamber is one cycle. Every time when the fine sand is all in the bottom cavity, the single fine sand will go through the same cycle every time the single fine sand is completely dropped. So the hourglass is often used to measure time. With the development of science and technology, there are more and more time judging tools. The traditional hourglass structure itself is difficult to connect with electronic devices. The t...
