Device for detecting and sensing fire in house

Abstract

The invention relates to the technical field of fire detection equipment, and particularly discloses a house internal fire detection and induction device which comprises a fire extinguishing agent box, a spraying system is arranged at the bottom of the fire extinguishing agent box, and a plurality of fire detection and extinguishing mechanisms are arranged at the bottom of the fire extinguishing agent box. In the rotating process of the corrugated sleeve, the bottom end of the corrugated sleeve is opened into an annular shape due to the centrifugal force of the corrugated sleeve, so that an ignition point is covered in the falling process, the ignition point is prevented from igniting other objects under the action of the flame-retardant cloth on the inner surface and the outer surface of the corrugated sleeve, the ignition point is isolated from external air to a certain extent, and the safety of the device is improved. A carbon dioxide fire extinguishing agent is sprayed out through a mounting box and a horn mouth to accurately extinguish an ignition point covered in a corrugated sleeve, and the sprayed carbon dioxide fire extinguishing agent is blocked through the corrugated sleeve, so that the aim of reducing the fire behavior is fulfilled. And the sprayed carbon dioxide fire extinguishing agent is prevented from polluting other objects which are not on fire.

Description

technical field [0001] The invention relates to the technical field of fire detection equipment, in particular to a fire detection and induction device inside a house. Background technique [0002] Fire refers to a catastrophic burning phenomenon that is out of control in time or space; among various disasters, fire is one of the most frequent and common major disasters that threaten public safety and social development; humans can use and control fire , is an important symbol of the progress of civilization; therefore, the history of human use of fire and the history of fighting against fire go hand-in-hand. Hazards caused by humans; people need to escape safely and quickly in the event of a fire. [0003] With the advancement of science and technology, furniture and other items in people's houses are gradually enriched, and the items placed in their houses are gradually increasing, which has a great fire hazard. When a fire occurs, a large number of items will be quickly ...

Problems solved by technology

[0003] With the advancement of science and technology, the items such as furniture in people's houses are gradually enriched, and the items placed in their houses are gradually increasing, which has a great fire hazard. Therefore, fire detection and sensing devices are installed inside many houses, but when the existing fire detection and sensing devices are in use, when the fire is extinguished after detection and induction, the ignition point of the fire may only be in a local area, but during the fire extinguishing process It will cause a large amount of fire extinguishing materials to be contaminated in the area where the fire did not occur, resulting in dirt and damage to the items that are not on fire. Therefore, in order to solve such problems, we propose a fire detection sensor device inside the house
