A cushion type pressure switch

Abstract

A cushion type pressure switch includes an air cushion, and a partition arranged in the air cushion, the partition is made of insulating material, and arc-shaped holes are arranged on the partition, and the partition divides the inflatable cushion into an upper space and a lower space, The upper layer of conductive tinfoil is provided on the wall of the upper space, and the lower layer of conductive tinfoil is provided with the lower layer of conductive tinfoil. The upper layer of conductive tinfoil and the lower layer of conductive tinfoil are respectively electrically connected to the relay; The paper contacts the relay and the power supply through the arc-shaped hole of the partition to form a circuit, and the upper layer of conductive tinfoil paper does not contact the lower layer of conductive tinfoil paper, and the relay is disconnected from the power supply. The invention has the advantages of simple structure, and the switch can be turned on when a person sits and turned off when a person walks through the switch controlled by the person himself.

Description

technical field [0001] The invention relates to a cushion type pressure switch, in particular to a switch that can be turned on or off by changing pressure. Background technique [0002] At present, household appliances such as electric fans and electric heaters are becoming more and more popular, but they are accompanied by great potential safety hazards in electricity consumption. Take electric heaters as an example. For heating, its high power is unavoidable. Once it is used improperly, it will cause a fire like similar electrical appliances such as fast heating. When people leave, they fail to turn off the electric heater in time, which is an important reason for causing fires. If a switch can be designed, people can start the electric fan and electric heater when they leave, and the side of the electric fan and electric heater will be automatically closed. The above-mentioned goals can be achieved through a complex induction system, but the cost is high, which is not c...

[0002] At present, household appliances such as electric fans and electric heaters are becoming more and more popular, but they are accompanied by great potential safety hazards in electricity consumption. Take electric heaters as an example. For heating, its high power is unavoidable, once it is used improperly, it will cause a fire like similar electrical appliances that heat up quickly, etc.

When people leave, they fail to turn off the electric heater in time, which is an important reason for causing fires. If a switch can be designed, people can start the electric fan and electric heater when they leave, and the side of the electric fan and electric heater will be automatically closed. The above goals can be achieved through a complex sensing system, but the cost is high, which is not conducive to promotion
