Another type is installed on a handbarrow, carried by two or more persons, lay aside in a fixed position such as a fire fighting truck or working site easily to get fire accident. This type cannot move easily to the place an accident take place.
[0003] FIG. 1 is a block diagram of the structure of a fog extinguisher of the prior art. The water tank 102 stores a definite amount of water, for example, a 100-liter large tank. There is an inlet pipe 104 in the top or in one side of the tank. Pump 106 is driven by a small engine or a motor 108 to produce high pressure of water, water is ejected from nozzle 110 via water pipe 112.This type of fog-generator is used for extinguishing only. The drawback is too expensive, and the nozzle structure is so delicate that it would be blocked by particles and become inactive, especially not in use for a long time (always so, because fire accident do not occur frequently), it is easily to become rusty or blocking, and cannot be used in emergency. Other washing apparatus such as car washer or floor washer are very different from the extinguisher in nozzle and overall structure of the apparatus. The car washer mainly uses a strong water column or water drops to wash a car, do not use a special nozzle to form droplet. The simple structure and the nozzle are not suitable for extinguishing. Examples such as the Kränle product of a Germany company, the product in a catalogue of Interpump group of an Italian company and other commercial available car washer.
[0004] Besides, the foam extinguisher uses corrosiveness chemical to form a large quantity of foam for fire extinguishing, it hurts persons, delicate instruments, computers or electric equipments. Although it can put out of a fire, but cleaning after firing, hurting human and animals become its defects.
[0005] A fog-generator, which is moveable easily and has multi-function, is not available in the prior art. What is needed is an improved apparatus, which is moveable easily and multi-functional. In peacetime, there is no fire accident to be put out, the apparatus could be used for car washing, floor washing, wall of a building washing, swimming pool washing, sprinkling, insecticide spraying and cooling with fog to decrease temperature, etc. Through operating of the apparatus every day, the operation became accustom to the user, thus prevent the miss-operation or loss efficiency of the apparatus in emergency.
