1. Fields of the Invention
The present invention relates to a fire distinguishing device, and more particularly, to a foam-type fire distinguishing device providing more foam to cover a larger area.
2. Descriptions of Related Art
The conventional foam-type fire distinguishing device generally mixes water and foam agent to generate foam-water mixture which is pressurized to be sprayed out from the spray device. The conventional foam-type fire distinguishing device comprises a pump, two mixing tanks, a pressure tank, a foam agent container and spray device. The pump sends water to the first mixing tank so as to be mixed with the foam agent delivered from the foam agent at the ratio about 1:100. When the water-foam mixture passes through the mixing tank, pressurized air is introduced into the second mixing tank from the pressure tank to create the desired water-foam mixture which is sprayed from the spray device to distinguish fire. It is known that the higher density of the foam, the less oxygen is provided to the fire, nevertheless, the pressurized air of the conventional foam-type fire distinguishing device is directly introduced into the second mixing tank which has limited space so that the water-foam mixture cannot contain sufficient foams and the foams are too large to efficiently separate the oxygen from the fire.
The present invention intends to provide a foam-type fire distinguishing device to eliminate the shortcomings mentioned above.
The present invention relates to a foam-type fire distinguishing device and comprises a water supply unit, a container, a mixing tank, an increasing pressure tank, a pressure device, a transmitting unit and a spray device. The transmitting unit delivers water from the water supply unit and the foam agent from the container to be mixed in the mixing tank to create the water-foam mixture which is then sent to the increasing pressure tank which introduces pressurized air to the water-foam mixture to create fine foams. The water-foam mixture with fine foams are sprayed from the spray device to increase the spread area to increase the efficiency of distinguishing fire.
The primary object of the present invention is to provide a foam-type fire distinguishing device that reduces the resistance in the pipes and increases the spray speed so as to cover a larger area and have more fine foams.
Another object of the present invention is to provide a foam-type fire distinguishing device that is able to be used in different types of buildings and the foam-type fire distinguishing device is cooperated with a movable base that is easily moved to desired areas to distinguish the fire.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

The transmitting unit 60 delivers the water from the water supply unit 10 and the foam agent from the first container 20 at a desired ratio to the mixing tank 30 to create water-foam mixture. The water-foam mixture is then sent to the increasing pressure tank 40. The pressure device 50 introduces pressurized air into the increasing pressure tank 40 to create fine foams to the water-foam mixture and increase the density of the fine foams in the water-foam mixture. The spray device 70 has an input end 71 and an output end 72, the input end 71 is connected with the second exit 43 of the increasing pressure tank 40. The spray device 70 has a trigger 73 to control the spray action of the spray device 70.
