Description

Technical Field

[0001] The invention relates to the technical field of smoke alarms, in particular to a kitchen smoke alarm. Background Art

[0002] Kitchens are places where open flames are often used. The fuels used are generally liquefied petroleum gas, coal gas, natural gas, etc. If they are not handled properly, they can easily cause leakage, combustion, and explosion. Smoke alarms achieve fire prevention by monitoring the concentration of smoke. They use ion smoke sensors inside. Ion smoke sensors are technologically advanced, stable and reliable sensors that are widely used in various fire alarm systems. Their performance is far superior to gas-sensitive resistor fire alarms.

[0003] The smoke alarm currently used achieves the warning function through the cooperation of smoke sensor and buzzer. The kitchen environment is relatively humid all year round, and oil smoke can easily accumulate and adhere to the surface of walls, flues and range hoods. If it is not cleaned in time, a fire may be caused when a chef's frying pan catches fire when cooking at high heat. Since the alarm in the prior art has no self-protection function inside, the alarm is baked by the continuous high temperature of the flame, and the connecting wires and electrical components inside the alarm are melted, and the alarm stops the alarm function.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figure 1-Figure 9 As shown, a kitchen smoke alarm according to the present invention comprises an alarm body 1, a connecting mechanism 2, a mounting seat 3 and a protection mechanism 4. A plurality of connecting mechanisms 2 are fixedly mounted on the top of the alarm body 1, a mounting seat 3 is arranged above the connecting mechanism 2, and a protection mechanism 4 is arranged inside the alarm body 1;

[0033] The protection mechanism 4 includes a protective cover 41, a support rod 42, a fixing block 43 and a second spring 44. A plurality of support rods 42 are evenly fixedly installed at the bottom end of the protective cover 41, and the ends of the plurality of support rods 42 away from the protective cover 41 are all movable through the bottom end of the alarm body 1 and extend to the outside of the alarm body 1. The end of the support rod 42 away from the protective cover 41 is fixedly connected with a fixing block 43. A second spring 44 is arranged on the outside of the support rod 42. One end of the second spring 44 is fixedly connected to the bottom end of the protective cover 41 and the other end is fixedly connected to the inside of the alarm body 1. The bottom end of the alarm body 1 is fixedly connected to the wall, and a water spray mechanism 6 is provided inside the alarm body 1. In case of fire, if the fire source cannot be dealt with in time, when the fire is too large, the smoke sensor and the buzzer inside the alarm body 1 are protected by the protective cover 41 to prevent the flame from burning the wires of the smoke sensor and the buzzer inside the alarm body 1, causing the alarm body 1 to directly lose the alarm function, so that the alarm body 1 continues to alarm, which greatly enhances the possibility of people discovering abnormalities in the alarm body 1 and improves people's safety.

[0034] like Figure 2 As shown, the material of the fixing block 43 is a low melting point alloy material.

[0035] It should be noted that when a fire occurs in a house and is not discovered in time, the flames and the temperature in the house melt the fixing block 43, and the fixing block 43 loses its fixing effect on the support rod 42, so that the protective cover 41 quickly protects the smoke sensor and the buzzer, reducing the possibility of the flame quickly burning the smoke sensor and the buzzer.

[0036] In this embodiment, the water spray mechanism 6 includes a first connecting pipe 61, a second connecting pipe 62, a connecting rope 63 and an impact plate 64. The first connecting pipe 61 is installed through the top of the alarm body 1, and the second connecting pipe 62 is installed through the bottom of the protective cover 41. The outer diameter of the first connecting pipe 61 is equal to the inner diameter of the second connecting pipe 62. An impact plate 64 is provided below the alarm body 1. A plurality of connecting ropes 63 are fixedly installed at the bottom of the alarm body 1, and the material of the connecting ropes 63 is steel wire. One end of the connecting rope 63 away from the alarm body 1 is fixedly connected to the top of the impact plate 64, and one end of the second connecting pipe 62 away from the first connecting pipe 61 is connected to the top of the impact plate 64. Fitting, a first fixing rod 611 is fixedly installed on the inner wall of the first connecting tube 61; a movable rod 612 is movably installed at the top and bottom of the first fixing rod 611, a water baffle 613 is fixedly installed at one end of the movable rod 612 away from the first fixing rod 611, a positioning groove 615 is opened at the bottom end of the water baffle 613, a first limiting block 614 is provided below the water baffle 613, and the outer side of the first limiting block 614 is fixedly connected to the inner wall of the first connecting tube 61, a second fixing rod 621 is fixedly installed on the inner wall of the second connecting tube 62, a push rod 622 is fixedly installed at the top of the second fixing rod 621, and the outer diameter of the push rod 622 is equal to the size of the positioning groove 615;

[0037] In the embodiment of the present invention, during the upward movement of the protective cover 41, the second connecting tube 62 also moves upward. At this time, the bottom end of the second connecting tube 62 is separated from the top end of the impact plate 64. At this time, the impact plate 64 is suspended on the bottom end of the alarm body 1 by the connecting rope 63. As the protective cover 41 rises, the second connecting tube 62 inserts the first connecting tube 61 into the inside. When the top end of the push rod 622 hits the positioning groove 615, it continues to push upward. At this time, the water baffle 613 will be pushed upward, and the movable rod 612 slides upward inside the first fixed rod 611. At this time, water begins to flow into the second connecting tube 62 through the first connecting tube 61, and sprays out from the bottom end of the second connecting tube 62, controlling the surrounding flames to a certain extent, and buying more time for rescue personnel to reduce the spread of the fire.

[0038] like Figure 2As shown, the material of the impact plate 64 is iron, and a magnet is fixedly installed at the joint between the second connecting pipe 62 and the impact plate 64. A conical block 10 is fixedly installed on the top of the impact plate 64. A stabilizing mechanism 5 is provided inside the alarm body 1. In normal times, the impact plate 64 can play a dustproof role to prevent mosquitoes and dust from entering the interior of the alarm body 1 and affecting the functionality of the alarm body 1. When the second connecting pipe 62 moves upward, the impact plate 64 can be quickly separated from the second connecting pipe 62, and the water flow is sprayed outward from the bottom end of the second connecting pipe 62, and when it impacts the conical block 10, it is evenly moved along the impact plate 64. The plate 64 splashes in all directions, which can increase the coverage area of ​​the flame by the water flow and increase the suppression effect on the fire. A third spring 9 is provided on the outer side of the movable rod 612, and one end of the third spring 9 is fixedly connected to the bottom end of the first fixed rod 611, and the other end of the third spring 9 is fixedly connected to the top of the water baffle 613. In the absence of a fire, the third spring 9 squeezes the water baffle 613, thereby increasing the tightness of the fit between the water baffle 613 and the first limit block 614, preventing water leakage caused by loosening of the fit between the water baffle 613 and the first limit block 614 due to wall vibration, thereby ensuring the stability of the device.

[0039] Specifically, the stabilizing mechanism 5 includes a stabilizing member 51 and a roller 52. A plurality of stabilizing members 51 are fixedly installed on the inner wall of the alarm body 1. A roller 52 is movably installed on one end of the stabilizing member 51 close to the protective cover 41. The outer side of the roller 52 fits with the outer wall of the protective cover 41. When the protective cover 41 moves upward, the outer side of the protective cover 41 moves upward along the rolling of the roller 52 under the limiting action of the stabilizing member 51, thereby preventing the protective cover 41 from shifting in position during the upward movement, thereby ensuring the accuracy of the docking between the first connecting tube 61 and the second connecting tube 62.

[0040] Specifically, the connecting mechanism 2 includes a first slot 21, a second slot 22, a sliding plate 23, a first spring 24, a triangular block 25, a third slot 26 and a triangular slot 27. The connecting mechanism 2 is provided with a first slot 21 inside, and second slots 22 are provided on both sides of the first slot 21. A first spring 24 is provided inside the first slot 21. Two sliding plates 23 are slidably installed inside the first slot 21. The sides of the two sliding plates 23 that are close to each other are respectively fixedly connected to the two ends of the first spring 24. The sides of the two sliding plates 23 that are away from each other are both fixedly installed with triangular blocks 25, and the triangular blocks 25 extend to the outside of the connecting mechanism 2 through the second slot 22. The bottom end of the mounting seat 3 is provided with a third slot 26 equal in number to the connecting mechanism 2, and two triangular slots 27 are provided on both sides of the third slot 26.

[0041] In the embodiment of the present invention, people can hold the alarm body 1 with their hands and pull the alarm body 1 downward with force. At this time, the triangular block 25 will be subjected to the squeezing force, causing the sliding plates 23 to move closer to each other. When the connecting mechanism 2 is pulled out from the inside of the third slot 26, the water supply pipe 32 is also separated from the first connecting pipe 61. Since the water supply pipe 32 is connected to the water source, the water supply pipe 32 starts to spray water outward at this time. The plug-in structure is simple to install. In effective or seconds, the alarm body 1 can be directly unplugged, and the water supply pipe 32 sprays water outward, which increases the timeliness of fire extinguishing.

[0042] Specifically, a fourth slot 31 is provided inside the mounting seat 3, a water pipe slot 33 is provided at the bottom end of the fourth slot 31, and the water pipe slot 33 penetrates the bottom end of the mounting seat 3, a water supply pipe 32 is provided inside the fourth slot 31, and the outer diameter of the water supply pipe 32 is equal to the inner diameter of the first connecting pipe 61, one end of the water supply pipe 32 penetrates the top end of the mounting seat 3, and the other end extends to the outside of the bottom end of the mounting seat 3 through the water pipe slot 33;

[0043] In the embodiment of the present invention, the water supply pipe 32 is pulled downward by hand to completely pull out the water supply pipe 32 inside the fourth slot 31. At this time, water can be accurately sprayed on the source of the fire to achieve the effect of rapid fire extinguishing, avoid further spread of the fire, and accurately spray the fire source to increase the rate of fire extinguishing.

[0044] As an optimized technical solution of the present invention, the mounting base 3 is provided with a limiting groove 7 below the water pipe groove 33, and a second limiting block 8 is fixedly installed on the outer side of the water supply pipe 32 passing through the water pipe groove 33, and the top of the second limiting block 8 is in contact with the top of the limiting groove 7. Through the limiting effect of the second limiting block 8 and the limiting groove 7, the water supply pipe 32 and the first connecting pipe 61 are prevented from being tightly connected when the alarm body 1 and the mounting base 3 are docked and installed, thereby preventing water leakage, and at the same time, the connection method is also made simpler.

[0045] Working principle: the staff first uses a screwdriver or other tools to fix the mounting base 3 on the roof of the kitchen, and at the same time connects the water supply pipe 32 that runs through the top of the mounting base 3 to the water source. At this time, the staff picks up the alarm body 1, aligns the connecting mechanism 2 with the third slot 26, and inserts the connecting mechanism 2 into the third slot 26 with force. At this time, the triangular block 25 is squeezed and the squeezing force is transmitted to the sliding plate 23. The sliding plate 23 begins to move closer to each other inside the first slot 21. At this time, the first spring 24 is compressed by force. As the connecting mechanism 2 continues to penetrate into the third slot 26, when the triangular block 25 moves to the triangular slot 27, the elastic potential energy of the first spring 24 is released, pushing the sliding plate 23 away. At this time, the triangular block 25 is stuck in the triangular slot 27. At this time, through the limiting action of the second limiting block 8 and the limiting slot 7, the water supply pipe 32 at the bottom of the mounting base 3 is also inserted into the first connecting pipe 61. At this time, the water supply pipe 32 is continuously supplied with water, and the installation is completed.

[0046] When the kitchen is on fire, thick smoke begins to rise along with the fire. When the smoke is captured by the smoke sensor (the smoke sensor is a prior art) through the air inlet of the alarm body 1, the buzzer (the buzzer is a prior art) inside the alarm body 1 starts to start and makes a sound to remind people to avoid risks. At this time, if the fire is not big, people can hold the alarm body 1 with their hands and pull the alarm body 1 downward with force. At this time, the triangular block 25 will be squeezed, so that the sliding plates 23 move closer to each other. When the connecting mechanism 2 is pulled out from the inside of the third slot 26, the water supply pipe 32 is also separated from the first connecting pipe 61. Since the water supply pipe 32 is connected to the water source, the water supply pipe 32 starts to spray water outward. At this time, the water supply pipe 32 can also be pulled down by hand to pull all the water supply pipes 32 inside the fourth slot 31 out. At this time, the water pipe can be accurately sprayed at the source of the fire to achieve the effect of rapid fire extinguishing and prevent the further spread of the fire.

[0047] If it is late at night when the alarm body 1 sounds an alarm, people cannot discover the fire in time and cannot control the flame in time. At this time, the fire will gradually grow larger and the temperature in the room will also rise. When the fixing block 43 reaches the melting point, the fixing block 43 will fall off from the support rod 42. At this time, the support rod 42 loses the fixing effect of the fixing block 43 on it. The second spring 44 is previously in a compressed state. With the release of the elastic potential energy of the second spring 44, the second spring 44 pushes the protective cover 41 upward (the smoke sensor and the buzzer are both installed on the top of the inner wall of the alarm body 1, and the area they occupy is smaller than the area of ​​the protective cover 41). At this time, the protective cover 41 covers the smoke sensor and the buzzer inside the protective cover 41. During the upward movement of the protective cover 41, the outer side of the protective cover 41 moves upward along the rolling of the roller 52 under the limiting effect of the stabilizing member 51, so as to prevent the protective cover 41 from shifting in position during the upward movement.

[0048] At the same time, during the upward movement of the protective cover 41, the second connecting tube 62 also moves upward. At this time, the bottom end of the second connecting tube 62 is separated from the top end of the impact plate 64. At this time, the impact plate 64 is suspended at the bottom end of the alarm body 1 by the connecting rope 63. As the protective cover 41 rises, the second connecting tube 62 inserts the first connecting tube 61 into the inside. When the top end of the push rod 622 hits the positioning groove 615, it continues to push upward. At this time, the water retaining plate 613 will be pushed upward, and the movable rod 612 slides upward inside the first fixed rod 611. At this time, The water starts to flow into the second connecting pipe 62 through the first connecting pipe 61, and is ejected outward from the bottom end of the second connecting pipe 62. When it hits the conical block 10, it is evenly splashed around along the impact plate 64, controlling the surrounding flames to a certain extent, buying more time for rescue personnel to reduce the spread of the fire. The triangular block 25 is made of plastic. When the fire is large, the temperature gradually increases. When it reaches the melting point of the triangular block 25, the triangular block 25 melts and falls off. At this time, the water supply pipe 32 sprays a large amount of water to extinguish the fire.
