Emergency lamp based on smoke alarm

Abstract

The invention discloses an emergency lamp based on a smoke alarm. The emergency lamp comprises a cylinder arranged on the wall top. The cylinder is in a hollow structure. A motor installed in the walltop is arranged above the cylinder. An output shaft of the motor is clamped to the upper portion of the cylinder. A rotating shaft is arranged on the output shaft. The lower end of the rotating shaftis in a curved shape. The rotating shaft extends out of the cylinder. A bulb is arranged on the end portion of the rotating shaft. The bulb is provided with a second smoke sensor. A control switch used for controlling the bulb to be turned on or off is arranged on the lower end portion of the rotating shaft. Two air cylinders arranged symmetrically along the rotating shaft are arranged in the cylinder. A baffle capable of telescoping is fixed to a piston rod of each air cylinder. A first electromagnetic valve in a normal open state is arranged on the portion located on a pipe opening. A firstsmoke sensor attached to the surface of the cylinder closely is arranged on the portion located in a smoke collecting pipe. The first smoke sensor and a second smoke sensor are electrically connectedwith a microprocessor. The microprocessor is electrically connected with the control switch, the first electromagnetic valve, the second electromagnetic valve and the motor. The safety road can be guided and illuminated.

Description

technical field [0001] The invention belongs to the technical field of household appliances, in particular to an emergency light based on a smoke alarm. Background technique [0002] Smoke alarm, also known as the first smoke sensor. Powered by the bus, there can be more than one connected to the bus, which can be networked and communicated with the fire alarm controller to form an alarm system. The alarm system is generally used in public places such as shopping malls. Therefore, smoke alarms will also be used in public places such as shopping malls. Smoke alarms are mainly used to detect fires. In order to prevent the smoke from the fire from hindering people's way of survival, emergency lights used in conjunction with smoke alarms are also installed in public places such as shopping malls.

Problems solved by technology

In order to prevent the smoke from the fire from hindering people's way of survival, emergency lights used in conjunction with smoke alarms are also installed in public places such as shopping malls. However, the general emergency lights are installed below the wall, and an arrow direction is used to guide the safety exit. And when breaking out of fire, often appear smoke can permeate the whole shopping mall, make people's both eyes can't see the route of advancing clearly, and the light of emergency light can only let people see the arrow, but can't shine the way of people's progress, especially in the At the crossroads, people cannot judge that there are other intersections, so they can only crawl forward by the light of emergency lights, move slowly, and it is not easy to escape from the fire scene
