Abstract

The invention relates to a fire extinguisher. A fire extinguisher output pipe capable of reducing pressure comprises a pipe body, the outlet end of the pipe body is provided with a pressure reducing head and a pressure reducing cover, the pressure reducing head is internally provided with a fire extinguishing agent discharge channel, one end of the fire extinguishing agent discharge channel is provided with an inlet hole abutting with an outlet of the pipe body, the other end of the fire extinguishing agent discharge channel is provided with an outlet hole, the sum of the opening area of the inlet hole is greater than the sum of the opening area of the outlet hole, the outlet hole is located in one end of the pressure reducing cover, and one end face of the other end of the pressure reducing cover is provided with a grid hole. The fire extinguisher output pipe capable of reducing pressure can reduce pressure of an out-spared fire extinguishing agent, has the advantages of simple structure, and solves the problem that fire extinguisher output pipes in the prior art cannot prevent ignition point spattering by a simple structure.

Description

technical field [0001] The invention relates to a fire extinguisher, in particular to a depressurizable fire extinguisher output pipe. Background technique [0002] A fire extinguisher is a portable fire extinguishing tool. A fire extinguisher is placed in the fire extinguisher to put out the fire. Fire extinguishers are one of the common fire prevention facilities. They are stored in public places or places where fires may occur. Different types of fire extinguishers contain different ingredients and are specially designed for different fire alarms. A fire extinguisher is disclosed in a patent document whose Chinese patent number is 2014101161301, the publication date is June 18, 2014, and the name is "multifunctional analog fire extinguisher and its use method". The basic structure of the fire extinguisher is as disclosed in this patent document, including a fire extinguisher cylinder and a fire extinguisher output pipe connected to the fire extinguisher cylinder. During...
