in the embodiment of the invention, the water supply pipe 32 is pulled downwards by hand, and the water supply pipe 32 in the fourth groove 31 is pulled out completely, so that water can be sprayed to the source of fire accurately, the effect of quickly extinguishing fire is achieved, the fire is prevented from further spreading, the fire source is sprayed accurately, and the fire extinguishing speed is increased.
As an optimized technical scheme of the invention, the mounting base 3 is provided with a limiting groove 7 below the water pipe groove 33, the outer side of the water supply pipe 32 penetrating through the water pipe groove 33 is fixedly provided with a second limiting block 8, the top end of the second limiting block 8 is attached to the top end of the limiting groove 7, and the problem of water leakage caused by the fact that the water supply pipe 32 is not tightly connected with the first connecting pipe 61 when the alarm main body 1 is in butt joint with the mounting base 3 is prevented through the limiting action of the second limiting block 8 and the limiting groove 7, and meanwhile, the connection mode is simpler.
The working principle is as follows: the worker firstly fixes the mounting base 3 on the roof of the kitchen by using a tool such as a screwdriver and the like, simultaneously connects the water supply pipe 32 penetrating through the top end of the mounting base 3 with a water source, at the moment, the worker takes up the alarm main body 1 again, aligns the connecting mechanism 2 with the third open slot 26, inserts the connecting mechanism 2 into the third open slot 26 with force, at the moment, the triangular block 25 is extruded, transmits the extrusion force to the sliding plate 23, the sliding plate 23 starts to move close to each other in the first open slot 21, at the moment, the first spring 24 is compressed under force, along with the continuous penetration of the connecting mechanism 2 in the third open slot 26, when the triangular block 25 moves to the triangular slot 27, the elastic potential energy of the first spring 24 is released, the sliding plate 23 is pushed away, at the moment, the triangular block 25 is clamped into the triangular slot 27, at the moment, the second limit block 8 and the limit slot 7 are inserted for limiting, and the water supply pipe 32 at the bottom end of the mounting base 3 is also inside the first connecting pipe 61, at this time, the installation is completed when the water supply pipe 32 is continuously supplied with water;
when a fire occurs in a kitchen, the smoke begins to rise along with the fire, after the smoke is caught by a smoke sensor (the smoke sensor is the prior art) through an air inlet of the alarm main body 1, a buzzer (the buzzer is the prior art) in the alarm main body 1 starts to sound, people are reminded to avoid risks, at the moment, if the fire is not strong, people can hold the alarm main body 1 with hands to forcibly pull the alarm main body 1 downwards, at the moment, the triangular block 25 receives extrusion force to enable the sliding plates 23 to move close to each other, when the connecting mechanism 2 is pulled out from the inside of the third open groove 26, at the moment, the water supply pipe 32 is separated from the first connecting pipe 61, and as the water supply pipe 32 is connected with a water source, at the moment, the water supply pipe 32 can be pulled outwards by hands, at the moment, the water supply pipe 32 can be pulled downwards to pull out all the water supply pipe 32 in the fourth open groove 31, at the moment, the water pipe can be accurately sprayed to the source of the fire, so that the effect of quickly extinguishing the fire is achieved, and the fire is prevented from further spreading;
if people cannot timely find that the fire cannot be controlled in time when the alarm main body 1 gives an alarm, the fire becomes larger gradually, the temperature in a room rises along with the rise of the fire, when the fixing block 43 reaches a melting point, the fixing block 43 falls off from the supporting rod 42, the supporting rod 42 loses the fixing effect of the fixing block 43 on the fixing block 42, the second spring 44 is in a compressed state, the second spring 44 pushes the protective cover 41 upwards along with the release of the elastic potential energy of the second spring 44 (the smoke sensor and the buzzer are both arranged at the top end of the inner wall of the alarm main body 1, the occupied area of the smoke sensor and the buzzer is smaller than that of the protective cover 41), the smoke sensor and the buzzer are arranged inside the protective cover 41 by the protective cover 41, and the outer side of the protective cover 41 moves upwards along the rolling of the roller 52 under the limiting effect of the fixing piece 51 in the upward movement process of the protective cover 41, preventing the shield 41 from being positionally displaced during the upward movement;
meanwhile, the second connecting pipe 62 also moves upwards in the upward movement process of the protective cover 41, the bottom end of the second connecting pipe 62 is separated from the top end of the impact plate 64, the impact plate 64 is hung at the bottom end of the alarm main body 1 by abutting against the connecting rope 63, the first connecting pipe 61 is sleeved inside by the second connecting pipe 62 along with the rising of the protective cover 41, when the top end of the push rod 622 is pushed to the positioning groove 615, the water baffle 613 is pushed upwards, the movable rod 612 slides upwards in the first fixing rod 611, water begins to flow into the second connecting pipe 62 through the first connecting pipe 61, the water is sprayed outwards from the bottom end of the second connecting pipe 62, the water uniformly sprays to the periphery along the impact plate 64 when impacting to the conical block 10, peripheral flames are controlled to a certain degree, more time is won for rescue personnel, the expansion of fire is reduced, the triangular block 25 is made of plastic, when the fire is great, the temperature rises gradually, and when reaching the melting point of triangle piece 25, the triangle piece 25 appears melting and drops, and at this moment, delivery pipe 32 sprays out a large amount of water, realizes putting out a fire.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the embodiments and descriptions given above are only illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the claims.
