Smoke alarm

Abstract

The invention discloses a smoke alarm, which comprises a body and a launching cavity with an upward opening, wherein the launching cavity is formed in the body, a smoke bomb combustion shell body is arranged in the launching cavity, the central position of the inner wall of the smoke bomb combustion shell body is fixedly connected with an ignition block cooperatively, the smoke bomb combustion shell body is filled with smoke ammunition, and a slidable smoke bomb device is arranged in the smoke bomb combustion shell body. According to the smoke alarm, the energy generated after the combustion of the smoke ammunition sends the smoke bomb device into the air, a trigger movable assembly is designed at first, thus the smoke bomb can be launched simply and conveniently, the smoke bomb device isdesigned at the same time, an inflatable activating assembly, a balloon inflatable assembly, a piston driving assembly and an inspiration assembly are designed in the smoke bomb device, a balloon marked with an SOS distress signal can be automatically inflated, and the smoke alarm is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of emergency alarm devices, in particular to a smoke alarm. Background technique [0002] With the development of the domestic economy and the improvement of people's living standards, personal travel has become more and more popular. Whether it is cliffs or deep mountains and old forests, travelers' footprints are all over the place, but danger is always around them. Therefore, tourism safety is particularly important. Without safety, there will be no tourism. Tourism safety is the lifeline of the tourism industry and the foundation and guarantee for the development of the tourism industry. For the traditional distress alarm device, people often think of lighting a fire to get smoke, but this often leads to The fire in Chengda, for many undeveloped natural scenic spots, does not have the conditions for radio communication, and the communication equipment is often in a state of no signal or poor signal.

[0002] With the development of the domestic economy and the improvement of people's living standards, personal travel has become more and more popular. Whether it is cliffs or deep mountains and old forests, travelers' footprints are all over the place, but danger is always around them. Therefore, tourism safety is particularly important. Without safety, there will be no tourism. Tourism safety is the lifeline of the tourism industry and the foundation and guarantee for the development of the tourism industry. For the traditional distress alarm device, people often think of lighting a fire to get smoke, but this often leads to The fire in Chengda, for many undeveloped natural scenic spots, does not have the conditions for radio communication, and the communication equipment is often in a state of no signal or poor signal. Common wireless transmitting terminals are either large in size or expensive in equipment, such as Many of the above shortcomings are often criticized by people. In order to solve the above technical problems and realize the timeliness of rescue and the minimization of losses, the traditional device can no longer meet the needs of existing rescue and personal travel. Therefore, an easy-to-operate , a smoke alarm with a high degree of automation
