Embodiment Construction

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when a part is said to be "fixed" to another part, it can be directly on the other part or there can be an intervening part. When a section is said to be "connected" to another section, it may be directly connected to the other section or there may be intervening sections at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to rep...

Abstract

The invention relates to a fire extinguishing apparatus. The fire extinguishing apparatus comprises a fire extinguishing container and multi-stage explosion venting structures. The fire extinguishing container is provided with a cavity, and the cavity is internally provided with an aerosol extinguishant. Each explosion venting structure comprises an explosion venting port formed in the fire extinguishing container and an explosion venting part arranged on the explosion venting port. When the pressure in the cavity reaches an explosion venting pressure, a fire extinguishing substance is sprayed out towards the cavity via the explosion venting part. The explosion venting pressures of the multi-stage explosion venting structures are increased successively. According to the fire extinguishing apparatus, under an extreme condition, when the pressure in the cavity cannot vent explosion via one or more explosion venting structures, fire extinguishing substances gathered in the cavity are increased. When the pressure in the cavity reaches the explosion venting pressures of the other explosion venting structures except the one or more explosion venting structures, the fire extinguishing substances are sprayed out towards the cavity via the explosion venting parts of the other explosion venting structures, such that the pressure in the cavity is guided effectively and released timely.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a fire extinguishing device. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's livelihood and safety awareness, fire-fighting equipment has been widely used, and fire-fighting facilities and fire-extinguishing devices are also equipped in many occasions. [0003] The fire extinguishing agent in the fire extinguishing device burns fast, which increases the instantaneous pressure inside the fire extinguishing device. The traditional fire extinguishing device cannot discharge the instantaneous pressure in time, which is prone to explosion and safety accidents. Contents of the invention [0004] Based on this, it is necessary to provide a relatively safe fire extinguishing device for the problem that traditional fire extinguishing devices are prone to safety accidents. [0005] An embodiment...
