The features such as, while also there are fire fighters to reach the scene of a fire and in many cases external fire-fighting equipment in Best Times
The problems such as being difficult to meet extinguishing operation task.
China at present《Code for fire protection design of buildings》(GB50016-2014), only it is regulation building height living more than 100m
Residence building should set automatic sprinkler system.In existing residential housing there are two types of fire-fighting fire extinguishing facilities, one hydrant system
House fire escape both sides are arranged on, there is cost is high, difficult in maintenance, normal function rate is low, water consumption is big, can not put out
The problems such as charging fire.
Secondly ammonium phosphate dry-powder fire extinguisher, on the one hand since it is desired that portable use, causes child's old man palm top to be stranded
On the other hand difficulty is influenced by factors such as intensity of a fire scene situation complexity, in fact it could happen that be difficult to approach the situation of fixed setting point, cause
Make not playing a role.
Obviously, existing residential housing fire-fighting fire extinguishing facility fails to control China's home fire that number and fire has occurred very well
Calamity death toll, therefore itself extinguishing ability of residential housing Nei Ge resident families primary scene how is relied on, it effectively controls and puts out a fire to save life and property
House initial fire disaster has become the subject there is an urgent need for research, is of great significance.
Invention content
In view of the deficienciess of the prior art, the object of the present invention is to provide a kind of simple water spray extinguishings of Household independent
Device and application method, for the type and feature of home fire, it is intended to realization is easily installed, low cost, response time are early,
The requirements such as the fiery rate height of initial stage control to improve residential housing from the anti-ability saved oneself, are effectively put out residential housing initial fire disaster, are subtracted
Few casualties and property loss.
To realize the above-mentioned technical purpose, used technical solution is the present invention：A kind of simple water spray of Household independent
