A FOG FIRE EXTINGUISHER FOR FIRE PREVENTION EDUCATION

摘要

Provided by the present invention is a smoke fire extinguisher for fire prevention education. The present invention comprises: a fire extinguishing head which is connected with an end of a spray tube and has an operation handle for opening and closing an internal flow path; an upper tank which is combined with the lower end of the fire extinguishing head and is supplied with vaporizing liquid and external air sequentially by a first check valve; a lower tank which is filled with the predetermined quantity of vaporizing liquid selectively supplied through the first check valve by being connected with the upper tank through a connection tube of a predetermined length and maintains internal pressure to be relatively higher than atmospheric pressure by external air supplied selectively through the first check valve; a vaporization discharge tube which has an open lower end dipped in the vaporizing liquid filling the lower tank, penetrates at least one air hole so that air in the lower tank flows in, and has an upper end penetrating the upper tank to be connected with an internal hole of the fire extinguishing head; a heater which has the vaporization discharge tube whose middle part is wound on the outer surface in a spiral form and generates electrical resistance heat when electrical power is applied by being connected with external power in order to perform vaporization by heating the vaporizing liquid discharged to the fire extinguishing head through the vaporization discharge tube; and a hollow cylindrical body which is connected with the upper tank at an upper end and protects the vaporization discharge tube and the heater from external environment by being connected with the lower tank at a lower end.
