DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] The household fire detection system of the present invention, if Figure 1 As shown, it includes a detection module 1 , a processing module 2 , a communication module 3 and a terminal device 4 , and the processing module 2 is connected to the terminal device 4 through the communication module 3 .

[0027] The detection module 1 is used to detect various environmental indicators during a fire, and specifically includes a plurality of fixed detection modules 11 and a mobile detection module 12 .

[0028] The fixed detection module 11 is fixedly installed at locations prone to fire, such as kitchens, near high-power electrical sockets, and near electrical appliances that generate high temperatures when operating (such as microwave ovens, induction cookers, and stoves). A fixed detection module 11 can be installed at each location prone to fire to detect whether a fire occurs at each location prone to fire.

[0029] Each fixed detection module 11 is provided with a first temperature sensor 111, a first smoke sensor 112 and a first camera 113. When a fire occurs, smoke with a temperature higher than normal temperature is generated. Therefore, the first temperature sensor 111 and the first smoke sensor 112 are used to detect the smoke concentration and temperature of the nearby air to determine whether a fire has occurred. The first camera 113 can capture video images of fire-prone locations, so that the homeowner can remotely observe whether a fire has occurred.

[0030] The mobile detection module 12 is a detection module that can automatically walk and patrol various locations in the house. Specifically, the mobile detection module 12 includes a mobile platform 121 that can walk according to a set route. The mobile platform 121 can adopt various existing mobile robots. The mobile platform 121 is provided with a second temperature sensor 122, a second smoke sensor 123 and a second camera 124. The second temperature sensor 122, the second smoke sensor 123 and the second camera 124 can also detect whether there is a fire nearby and shoot a video. The second temperature sensor 122, the second smoke sensor 123 and the second camera 124 can move to various locations with the mobile platform 121 to realize full-house patrol and also monitor locations that are not prone to fire.

[0031] The first temperature sensor 111, the first smoke sensor 112, the first camera 113, the mobile platform 121, the second temperature sensor 122, the second smoke sensor 123 and the second camera 124 are all connected to the processing module 2. Each detection element is connected to the processing module 2 via wifi, and transmits the detection signal to the processing module 2. The processing module 2 determines whether a fire occurs according to the detection signal. When a fire occurs, the processing module 2 sends a notification or alarm information to the terminal device 4 through the communication module 3, and transmits the video to the terminal device 4. The terminal device 4 can be a mobile phone or other device that is convenient for the homeowner to carry.

[0032] In the present invention, the fixed detection module 11 and the mobile detection module 12 can detect various positions in the house at the same time, with a wider detection range and more comprehensive detection. Regardless of whether a fire occurs in a position prone to fire or a position not prone to fire, the fire can be detected in time and the homeowner can be notified, which is conducive to timely extinguishing the fire and reducing losses.

[0033] When a fire occurs, smoke flows upward. If the second temperature sensor 122, the second smoke sensor 123, and the second camera 124 are installed at a low height, it is difficult to quickly detect the fire, and it is also difficult to detect a fire with a high ignition point. Figure 2 As shown, a detection arm 125 is provided on the mobile platform 121 of the present invention, and the second temperature sensor 122, the second smoke sensor 123 and the second camera 124 are all provided at the end of the detection arm 125. The mobile platform 121 can adopt a mobile robot with a low height, which is small in size and easy to manage. The detection arm 125 can be arranged vertically or tilted, and the second temperature sensor 122, the second smoke sensor 123 and the second camera 124 are all arranged at the upper end of the detection arm 125, which is conducive to rapid detection of fire.

[0034] In order to expand the detection range, the detection arm 125 includes a positioning sleeve 1251 and a telescopic arm 1252. The positioning sleeve 1251 is a circular sleeve. The telescopic arm 1252 can be a solid rod or a hollow rod to reduce weight. The lower end of the positioning sleeve 1251 is hinged to the mobile platform 121, and the positioning sleeve 1251 is connected to a first driving mechanism 1253 that drives the positioning sleeve 1251 to rotate up and down. The first driving mechanism 1253 can be a linear motor, a cylinder or other equipment, and its lower end is hinged on the mobile platform 121, and its upper end is hinged on the positioning sleeve 1251. A telescopic mechanism 1254 is arranged in the positioning sleeve 1251, and the telescopic mechanism 1254 can also be a linear motor, a cylinder or other equipment. The lower end of the telescopic arm 1252 extends into the upper port of the positioning sleeve 1251 and is connected to the telescopic mechanism 1254. The second temperature sensor 122, the second smoke sensor 123 and the second camera 124 are all arranged at the upper end of the telescopic arm 1252. The telescopic mechanism 1254 can push the telescopic arm 1252 to extend outward or retract inward into the positioning sleeve 1251 to adjust the total length of the detection arm 125, and the first driving mechanism 1253 can adjust the angle of the detection arm 125 to achieve detection at multiple heights and positions.

[0035] In order to detect the surroundings of the mobile platform 121, a turntable 126 is arranged on the top of the mobile platform 121. The turntable 126 is connected to a second driving mechanism 127 that drives the turntable 126 to rotate around its own center line. The second driving mechanism 127 can be a servo motor or other equipment. The positioning sleeve 1251 and the first driving mechanism 1253 are installed on the turntable 126. When the second driving mechanism 127 drives the turntable 126 to rotate, the turntable 126 drives the telescopic arm 1252 to rotate, which can change the detection positions of the second temperature sensor 122, the second smoke sensor 123 and the second camera 124, so that the surroundings of the mobile platform 121 can be detected.

[0036] When a fire occurs, in order to prevent the fire from spreading, it is necessary to extinguish the fire as soon as possible. If no one is in the house, it is difficult to extinguish the fire in time. In order to prevent the fire from spreading, especially when no one is at home, the fire location is automatically extinguished to reduce losses. In the present invention, a flexible water pipe 5 is also included, such as Figure 3 As shown, the water inlet end of the water pipe 5 is provided with a solenoid valve 51, which is connected to a household water connector, and the water outlet end of the water pipe 5 is provided with a horizontal first connector 52, and the outer wall of the first connector 52 is fixedly provided with a first magnetic block 53, which is in a circular shape and fixed to the outer wall of the outlet end of the first connector 52. The solenoid valve 51 is connected to the processing module 2.

[0037] A water spray head 128 is fixedly provided at the upper end of the telescopic arm 1252, the water spray head 128 is connected to a flexible delivery pipe 129, the delivery pipe 129 is connected to a second joint 1210, the second joint 1210 is horizontally fixed to the side wall of the mobile platform 121; a second magnetic block 1211 is fixedly provided on the outer wall of the second joint 1210. The second joint 1210 and the first joint 52 are at the same height.

[0038] The port of the first joint 52 is provided with a guide sleeve 54, the inner diameter of which increases from the inside to the outside, and the inner wall of the guide sleeve 54 is provided with an elastic sealing sleeve 55; the port of the second joint 1210 is provided with a guide tube 1212, the shape of which matches the shape of the guide sleeve 54. Figure 4 As shown, the guide tube 1212 can extend into the elastic sealing sleeve 55 and fit with the elastic sealing sleeve 55, and the second magnetic block 1211 can be magnetically connected with the first magnetic block 53. The first magnetic block 53 and the second magnetic block 1211 can be strong magnets.

[0039] When a fire occurs, the processing module 2 controls the mobile platform 121 to move to the first joint 52, and aligns the second joint 1210 with the first joint 52, and then the mobile platform 121 continues to move toward the first joint 52 until the second joint 1210 is inserted into the first joint 52, at which time the first magnetic block 53 contacts the second magnetic block 1211, and the first magnetic block 53 and the second magnetic block 1211 are tightly fitted together under the action of magnetic attraction, ensuring the stable connection between the second joint 1210 and the first joint 52. Then the mobile platform 121 moves toward the location of the fire, and the second magnetic block 1211 drives the first magnetic block 53 and the first joint 52 to move, and the flexible water pipe 5 is gradually pulled out. When the mobile platform 121 reaches the location of the fire, the processing module 2 controls the solenoid valve 51 to open, and the household water source flows to the sprinkler head 128 through the water pipe 5, the first joint 52, the second joint 1210 and the delivery pipe 129, and then sprays out from the sprinkler head 128 to extinguish the fire and prevent the fire from spreading.

[0040] In order to stably position the first joint 52, two upper and lower elastic clips can be used to clamp and fix the first joint 52. After the first joint 52 is connected to the second joint 1210, the first joint 52 moves with the second joint 1210, and the first joint 52 slides out of the elastic clip.

[0041] In the kitchen, the fumes produced by cooking are similar to the smoke produced by fire. It is not possible to accurately detect whether a fire occurs by relying solely on the first temperature sensor 111 and the first smoke sensor 112. Therefore, in order to improve the detection accuracy of the fixed detection module 11 in the kitchen, the fixed detection module 11 includes a kitchen detection module, which is installed in the kitchen, and the remaining fixed detection modules 11 are installed in the living room, bedroom, and bathroom where fire is likely to occur. Figure 5 As shown, the kitchen detection module includes a box body 114, a first camera 113 is arranged on the outer wall of the box body 114, an air flow channel 115 is arranged in the box body 114, an air intake fan 116 is arranged at the inlet of the air flow channel 115, a gas concentration sensor 119 is arranged in the air flow channel 115, a first temperature sensor 111 and a first smoke sensor 112 are arranged in the air flow channel 115, the air flow channel 115 is connected to a first three-way valve 117, one outlet of the first three-way valve 117 is connected to the outside of the box body 114, and the other outlet of the first three-way valve 117 is connected to a hydrogen chloride concentration detection chamber 118, a hydrogen chloride concentration detection mechanism is arranged in the hydrogen chloride concentration detection chamber 118, and the hydrogen chloride concentration detection mechanism is connected to the processing module 2.

[0042] The suction fan 116 can actively draw external air into the air flow channel 115 to promote air flow. When a fire occurs, smoke can flow into the air flow channel 115 more quickly and be detected.

[0043] The gas concentration sensor 119 can detect the gas concentration in the air and notify the homeowner in time when the gas leaks. The gas concentration sensor 119 is set according to the composition of the gas. For example, when natural gas is used as the gas, the gas concentration sensor 119 uses a methane sensor; when the gas provided by the gas tank is used as the gas, a carbon monoxide sensor can be used.

[0044] After detection by the first temperature sensor 111 and the first smoke sensor 112, if the temperature and smoke concentration of the gas are lower than the set value, the gas in the airflow channel 115 is discharged to the outside of the box body 114 through the first three-way valve 117. If the temperature and smoke concentration of the gas reach or exceed the set value, the gas in the airflow channel 115 is transported to the hydrogen chloride concentration detection chamber 118 through the first three-way valve 117, and the hydrogen chloride concentration in the gas is detected by the hydrogen chloride concentration detection mechanism. If the hydrogen chloride concentration is lower than the set value, it indicates that no fire has occurred. If the hydrogen chloride concentration reaches or exceeds the set value, it indicates that a fire has occurred.

[0045] The combustion of common water pipes, electrical appliance casings, plastic products, etc. in the kitchen will produce hydrogen chloride, but hydrogen chloride is not produced during the normal use of the stove. Therefore, by adding a hydrogen chloride concentration detection mechanism to detect the concentration of hydrogen chloride in the gas, it is used to assist in determining whether a fire has occurred. This can screen out misjudgments caused by increased temperature and smoke concentrations when cooking or when the stove is working normally, thereby improving the accuracy of kitchen fire detection.

[0046] In the present invention, the hydrogen chloride concentration detection mechanism includes a hydrogen chloride sensor 1110, and the hydrogen chloride sensor 1110 can be made of existing technology.

[0047] Compared with other places in the home, a large amount of oil smoke is generated in the kitchen, which is easy to adhere to the surface of the hydrogen chloride sensor 1110, the first temperature sensor 111 and the gas concentration sensor 119, which will affect the accuracy of detection after a long time. In order to clean the hydrogen chloride sensor 1110, the first temperature sensor 111 and the gas concentration sensor 119 in time, in the present invention, a nozzle 1111 is arranged in the organic gas detection chamber 118 of the hydrogen chloride sensor 1110 and the air flow channel 115, and the nozzle 1111 sprays toward the hydrogen chloride sensor 1110, the first smoke sensor 112 and the gas concentration sensor 119, and the nozzle 1111 is connected to the air pipe 1112, and the air pump 1113 is arranged on the air pipe 1112; a water washing chamber 1114 is arranged in the box body 114, and a water inlet is arranged at the top of the water washing chamber 1114, and a sealing plug 1116 is arranged in the water inlet, and a drain valve is arranged at the bottom. The washing chamber 1114 is filled with clean water, which can be an alkaline solution, to remove solid particles, acidic gas, oil smoke and other components in the gas. The side wall of the hydrogen chloride concentration detection chamber 118 is provided with a second three-way valve 1115, one outlet of the second three-way valve 1115 is connected to the outside of the box body 114, and the other outlet of the second three-way valve 1115 is connected to the bottom of the washing chamber 1114 through a pipeline, and the air pipe 1112 is connected to the top of the washing chamber 1114.

[0048] The gas inside the hydrogen chloride concentration detection chamber 118 can be discharged to the outside of the box body 114 through the second three-way valve 1115. When the hydrogen chloride sensor 1110, the first temperature sensor 111 and the gas concentration sensor 119 need to be cleaned, the gas in the air flow channel 115 is passed into the hydrogen chloride concentration detection chamber 118, and the gas in the hydrogen chloride concentration detection chamber 118 is passed into the water washing chamber 1114 through the second three-way valve 1115. After water washing, the gas pump 1113 sucks the gas in the water washing chamber 1114 into the air pipe 1112, and the gas flows along the air pipe 1112 to the nozzle 1111, and then sprays to the hydrogen chloride sensor 1110, the first temperature sensor 111 and the gas concentration sensor 119, and blows off some dust, particles and other materials on the surfaces of the hydrogen chloride sensor 1110, the first temperature sensor 111 and the gas concentration sensor 119.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
