Abstract
The utility model discloses a sound fire extinguishing demonstrator, which is characterized by comprising a base with one end provided with a candlestick. The other end of the base is provided with a sound box cover with the side face provided with an air hole; the sound box cover is internally provided with a sound-producing horn connected with a power amplifier; the sound box cover is provided with a funnel-shaped concentrator corresponding to the sound-producing horn; the tip of the concentrator is provided with an air flow outlet; the sound-producing horn is connected with a plug via a power line; and the sound-producing horn and the air flow outlet are in linear correspondence. According to the sound fire extinguishing demonstrator, the structure is reasonably designed, the air flow, generated inside the sound box cover, of the sound-producing horn is finally exhausted via the air flow outlet through the tip of the concentrator, the candle can thus be extinguished, special persons or places are not needed, the demonstration process is simple, convenient, and vivid, the vision of students is broadened, knowledge is enhanced, and the students can intuitively know different fire extinguishing principles, and the technical problems that use is limited, the process is tedious and the demonstration mode is boring can be solved.
Description
Technical field the utility model belongs to demonstration device technical field, is specifically related to the sound demonstration device of putting out a fire for a kind of demonstration lesson.
In background technology prior art, when student is carried out to the scientific popularization of safe fire extinction, often can instruct student to put out a fire in the mode of professional flame snuffer, although this instruction mode can play the effect of education, but operation needs professional to instruct often and in specific spacious place use, demonstration mode is single; This fire-fighting mode is not unique method yet, while particularly carrying out science popularization in school, often need to be simple in structure with some, understandable, and the mode of energy mobilizing students enthusiasm and learning interest guides formula teaching, can not only teach security knowledge like this, can also remove the principles of science about fray-out of flame of decorrelation by guiding student, like this could be real play teaching function, and the form of teaching that the professional fire extinguishing appliance of traditional use is demonstrated obviously can not meet current demand.
Summary of the invention the purpose of this utility model is that solution prior art existence use is limited, process is loaded down with trivial details and the single uninteresting technical matters of demonstration mode, provides a kind of sound fire extinguishing demonstration device, to overcome the deficiencies in the prior art.
To achieve these goals, a kind of sound fire extinguishing of the utility model demonstration device, its main points are that it comprises that one end is provided with the base of candlestick; The other end of described base is provided with the audio amplifier cover of side band bleeder vent; In described audio amplifier cover, be provided with the pronunciation loudspeaker that are connected with power amplifier; Described audio amplifier cover is provided with the be funnelform amplitude transformer mutual corresponding with the loudspeaker that pronounce; The place, tip of described amplitude transformer is provided with air stream outlet; Described pronunciation loudspeaker are connected with plug by power lead; Described pronunciation loudspeaker and air stream outlet are linearly corresponding.
Described power amplifier is arranged on panel, and power amplifier is connected with USB socket with the volume adjusting button being arranged on audio amplifier outside by wire.
The utility model reasonable in design, easy to use, because pronunciation loudspeaker finally can be discharged by the air stream outlet at amplitude transformer tip at the inner air-flow producing of audio amplifier cover, thereby candle is extinguished, without specific personnel and place, presentation process is easy, vivid, widened student's outlook, allowed student vividly get information about different fire-fighting principles.The utility model solved prior art use limited, process is loaded down with trivial details and the single uninteresting technical matters of demonstration mode.
Appended drawings is structural representation of the present utility model.
In figure 1, audio amplifier cover 2, pronunciation loudspeaker 3, amplitude transformer 4, base 5, candlestick 6, USB socket 7, volume adjusting button 8, candle 9, power amplifier 10, air stream outlet
Embodiment is with reference to accompanying drawing, and it comprises that one end is provided with the base 4 of candlestick 5 the utility model; The other end of described base 4 is provided with the audio amplifier cover 1 of side band bleeder vent; In described audio amplifier cover 1, be provided with the pronunciation loudspeaker 2 that are connected with power amplifier 9; Described audio amplifier cover 1 is provided with the be funnelform amplitude transformer 3 mutual corresponding with the loudspeaker 2 that pronounce; The place, tip of described amplitude transformer 3 is provided with air stream outlet 10; Described pronunciation loudspeaker 2 are connected with plug by power lead; Described pronunciation loudspeaker 2 and air stream outlet 10 are linearly corresponding; Described power amplifier 9 is arranged on panel, and power amplifier is connected with USB socket 6 with the volume adjusting button 7 being arranged on audio amplifier outside by wire.
The utility model is comprised of base and vertical audio amplifier cover, in audio amplifier cover, there are power amplifier and pronunciation loudspeaker, audio amplifier cover one side has the faceplate part of power amplifier, there are volume adjusting button and USB socket above, opposite side is the amplitude transformer covering on pronunciation loudspeaker, at the bottom of pronunciation loudspeaker and amplitude transformer, mouth is corresponding, and the candle that amplitude transformer air stream outlet is stood with certain distance is corresponding.
Principle of work: the utility model utilizes the air-flow of sound film generation of vibration, under the effect of amplitude transformer, from its most advanced and sophisticated air flow outlet ejection, candle is extinguished, during use, need bass, can regulate by volume adjusting button the size of volume, thereby regulate the size of air-flow, the flame of pronunciation loudspeaker, air stream outlet and candle must be arranged on same straight line; The mode of this knock down the flame and existing professional fire-fighting mode difference are obviously, without professional, use, without particular place, presentation process is vivid, widened student's outlook, the principle of having demonstrated intuitively the generation of wind and having utilized wind to put out a fire, has given full play to learning interest and enthusiasm, is deeply subject to liking of student.
