Liquid metal circuit switch device

Abstract

The invention provides a liquid metal circuit switch device which comprises an atmosphere layer, a liquid metal layer, a sealed cavity, two electrodes, a warning unit and a wireless transmission unit. The liquid metal layer and the atmosphere layer are located in the sealed cavity. The atmosphere layer is located above the liquid metal layer. The two electrodes are fixed on two opposite inner side walls of the sealed cavity. The liquid level of the liquid metal layer is in contact with the two electrodes. The warning unit is serially connected with the wireless transmission unit and then parallelly connected with the two electrodes in the sealed cavity and the liquid metal layer. The liquid metal circuit switch device has the advantages that the liquid metal circuit switch device can be mounted on an electric appliance and on a medical care instrument; when the electric appliance falls, a user can arrive on the site timely to avoid accidents such as a fire; when an aged person or a child who is inconvenient in moving falls, medical staff can arrive on the site for rescuing.

Description

technical field [0001] The invention relates to a switch device, in particular to a liquid metal circuit switch device. Background technique [0002] At present, in the scientific research of microelectronic devices, liquid metals are widely used as electrode materials due to their conductivity, low melting point, high boiling point and fluidity, and more and more people pay attention to their efficacy and application. Therefore, how to utilize these characteristics of liquid metal skillfully and more effectively is particularly important. When the temperature is from room temperature to 2400 degrees Celsius, liquid metal gallium is in a liquid state, and its conductivity is excellent, so it can be used in liquid switching devices. [0003] In people's production and life, the short circuit phenomenon caused by the dumping of electrical devices (such as electric heaters, electric irons, etc.) can easily cause accidents such as fires and electric injuries, endangering the pe...
