DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings and initially to FIGS. 1-3, a fire apparatus in accordance with the preferred embodiment of the present invention comprises a housing 1, a water tank 2 mounted in the housing 1 and containing water therein, a support unit 5 mounted on the housing 1, a spray gun 4 mounted on and supported by the support unit 5, a hose 33 having a first end connected with the water tank 2 and a second end connected with the spray gun 4, a drive motor 11 mounted in the housing 1 and electrically connected with the spray gun 4 to pressurize the spray gun 4, an electric storage unit 12 mounted in the housing 1 and electrically connected with the drive motor 11 to supply an electric power to the drive motor 11, an illuminating unit 6 mounted on the housing 1 and electrically connected with the electric storage unit 12, a substantially inverted U-shaped support rail 13 mounted on a top of the housing 1, and a plurality of castors 14 mounted on a bottom of the housing 1.
The water tank 2 is externally connected with an independent water source “W” that is located outside of the housing 1. The hose 33 is mounted in the housing 1 and is extendable outward from the housing 1. The hose 33 is made of a material (such as stainless steel) that can withstand a weight of at least sixty (60) kilograms. The hose 33 has a length of about ten to thirty (10-30) meters. The fire apparatus further comprises a bubble tank 20 mounted in the housing 1 and containing bubbles therein, and the first end of the hose 33 is selectively connected with the bubble tank 20.
The drive motor 11 is connected with the water tank 2 to pressurize the water tank 2 and the hose 33 and to deliver the water in the water tank 2 through the hose 33 into the spray gun 4. The drive motor 11 is selectively connected with the bubble tank 20 to pressurize the bubble tank 20 and the hose 33 and to deliver the water in the bubble tank 20 through the hose 33 into the spray gun 4.
The support unit 5 is located outside of the housing 1. The support unit 5 is provided with a microswitch 51 electrically connected with the drive motor 11 to control operation of the drive motor 11.
The spray gun 4 is provided with a trigger 41 and a spraying nozzle 42. The liquid contained in the spray gun 4 is pressurized by the drive motor 11 to form a high pressure liquid that is injected outward from the spraying nozzle 42 in an atomized manner. The spray gun 4 is removably mounted on the support unit 5. The spray gun 4 presses the microswitch 51 of the support unit 5 at a normal state so that the drive motor 11 stops operating at the normal state. The spray gun 4 is detached from the microswitch 51 of the support unit 5 when the spray gun 4 is removed from the support unit 5 so that the microswitch 51 of the support unit 5 is released to conduct and start the drive motor 11 which delivers the water in the water tank 2 through the hose 33 into the spray gun 4 and pressurizes the water in the spray gun 4 to form a high pressure water. In such a manner, when the trigger 41 of the spray gun 4 is pressed, the high pressure water in the spray gun 4 is injected and sprayed outward from the spraying nozzle 42 of the spray gun 4 in an atomized manner. On the contrary, when the trigger 41 of the spray gun 4 is released, the spray gun 4 stops spraying the atomized water, and when the spray gun 4 presses the microswitch 51 of the support unit 5, the drive motor 11 stops operating and releases the pressure in the hose 33.
The fire apparatus further comprises an independent power supply “P” electrically connected with the electric storage unit 12 to charge the electric storage unit 12. The independent power supply “P” is located outside of the housing 1. The electric storage unit 12 is a direct-current secondary battery that can be charged by the independent power supply “P” and can supply the electric power to the drive motor 11 during a period of time exceeding fifteen (15) minutes. The illuminating unit 6 is mounted on the top of the housing 1 and is located outside of the housing 1. The illuminating unit 6 is rotatable through three hundred and sixty degrees)(360°) to provide an illuminating effect to the user.
In operation, referring to FIGS. 4 and 5 with reference to FIGS. 1-3, the housing 1 is placed on a corner of a restaurant kitchen “R”. In such a manner, when fires happen at a determined location “F” in the restaurant kitchen “R”, the spray gun 4 is removed from the support unit 5 so that the microswitch 51 of the support unit 5 is released to conduct and start the drive motor 11 which delivers the water in the water tank 2 through the hose 33 into the spray gun 4 and pressurizes the water in the spray gun 4 to form a high pressure water. Thus, when the trigger 41 of the spray gun 4 is pressed, the high pressure water in the spray gun 4 is injected and sprayed outward from the spraying nozzle 42 of the spray gun 4 in an atomized manner so as to extinguish the fires at the determined location “F”. At this time, the atomized water injected from the spray gun 4 has smaller size. Thus, when the atomized water touches the fires, the atomized water is heated and vaporized into vapors so that the whole volume of the vapors is expanded largely to isolate the oxygen in the air from the fires so as to extinguish the fires easily and quickly. In addition, the atomized water will not conduct the electricity to prevent from causing an electric shock to the user. Further, the spray gun 4 is movable to extinguish the fires at the determined location “F” only without wetting the other place in the house to prevent from causing damage to the electric appliances in the house.
After the fires are extinguished, the trigger 41 of the spray gun 4 is released so that the spray gun 4 stops spraying the atomized water. Then, the spray gun 4 is placed on the support unit 5 and presses the microswitch 51 of the support unit 5 so that the drive motor 11 stops operating, and the pressure in the hose 33 is released to prevent the hose 33 from leaking due to an excessive pressure.
As shown in FIG. 6, the housing 1 is placed on a corner of a house kitchen “H”.
Accordingly, the spray gun 4 injects atomized water outward so as to extinguish the fires easily and quickly. In addition, the microswitch 51 of the support unit 5 can control operation of the drive motor 11 to release the pressure in the hose 33 after the fires are extinguished so as to prevent the hose 33 from leaking due to an excessive pressure. Further, the spray gun 4 is movable to extinguish the fires at the determined location “F” without wetting the other place in the house so as to prevent from causing damage to the electric appliances in the house. Further, the electric storage unit 12 is used to supply the electric power so that the spray gun 4 can be operated normally when the external power supply fails. Further, the illuminating unit 6 is rotatable freely so as to provide an illuminating effect to the user. Further, the water tank 2 is externally connected with an independent water source “W” to supply water to the spray gun 4 so that the spray gun 4 can inject atomized water successively.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
