Seat cushion type pressure switch

Abstract

The invention discloses a seat cushion type pressure switch which comprises an inflatable cushion, and a clapboard arranged in the inflatable cushion, wherein the clapboard is made of an insulating material; an arc-shaped hole is formed in the clapboard; the clapboard partitions off the inflatable cushion into an upper-layer space and a lower-layer space; upper-layer conductive tin foil paper is arranged on the wall of the upper-layer space; the lower-layer space is provided with lower-layer conductive tin foil paper; the upper-layer conductive tin foil paper and the lower-layer conductive tin foil paper are electrically and respectively connected with a relay; the upper-layer conductive tin foil paper and the lower-layer conductive tin foil paper are contacted with the relay and the power source through the arc-shaped hole of the clapboard to form a loop; the upper-layer conductive tin foil paper and the lower-layer conductive tin foil paper has no contact with the relay and are disconnected with the power source. The seat cushion type pressure switch has the advantages of being simple in structure, and being controlled by a user per se, so that the seat cushion pressure switch is switched on when a person sits thereon and switched off when the person leaves away.

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
