Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of gas detection, and more specifically, to a household combustible gas detector. Background Art

[0002] With the acceleration of the urbanization process, the number of buildings is increasing day by day, and the attention to fire safety is also increasing day by day, which has promoted the development of monitoring alarm technology. The intelligent trend is that traditional fire alarm systems are gradually transformed into intelligent and automated ones. By using advanced sensor technology, data analysis, and Internet of Things technology, the response speed and accuracy of the alarm system have been improved. The application of digital signal processing technology has significantly enhanced the sensitivity and reliability of the alarm, and at the same time, it is also convenient for data storage and transmission.

[0003] The patent with the patent announcement number CN220231658U relates to a household combustible gas detector, belonging to the technical field of combustible gas detectors, and solves the problem that users of existing household combustible gas detectors cannot confirm by themselves whether their detection function and alarm function are fault-free. A household combustible gas detector includes a detection housing. An induction cavity is provided on the left side inside the detection housing, and a group of smoke sensors are installed on the rear side of the inner end of the induction cavity. Through the interference induction of the perfume in the storage cavity on the smoke sensors, users can determine whether the current detection function and alarm function of the household combustible gas detector are operating normally, so as to avoid the situation where the combustible gas cannot be alarmed when there is a leakage due to a fault in the combustible gas detection function or alarm function. However, the installation of this device is very inconvenient, and when it needs to be repaired due to damage, the disassembly and maintenance are very inconvenient. Therefore, a household combustible gas detector is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] To overcome the above defects, embodiments of the present disclosure provide a household combustible gas detector, which solves the technical problem of very inconvenient disassembly and maintenance in the prior art.

[0005] According to one aspect, at least one embodiment of the present disclosure provides a household combustible gas detector, including a groove plate, an I-shaped plate is installed on the inner wall of the groove plate, a water inlet pipe is fixedly connected to the inner wall of the groove plate, an annular plate is fixedly connected to the bottom of the I-shaped plate, and a screw plate is fixedly connected to the left side of the groove plate; a fixing device is arranged on the inner wall of the groove plate, a collecting device is arranged at the bottom of the annular plate, and a spraying device is arranged at the bottom of the collecting device; the fixing device includes a first fixing plate, a first spring, a C-shaped plate, a second spring, and a blocking block. The first fixing plate is fixedly connected to the inner wall of the groove plate, and the first spring is fixedly connected to the right side of the first fixing plate. During installation, the screw plate is fixed to the wall, and the water inlet pipe is connected to ensure the water inlet of the water inlet pipe. At this time, the I-shaped plate is inserted into the groove plate, which can facilitate subsequent disassembly, repair or replacement, and improve the convenience and speed of device use. The C-shaped plate is fixedly connected to the right side of the first spring, the second spring is fixedly connected to the bottom of the inner wall of the groove plate, and the blocking block is fixedly connected to the top of the second spring. The surface of the C-shaped plate is in contact with the inner wall of the groove plate, and the surface of the C-shaped plate is in contact with the surface of the I-shaped plate. The inner wall of the groove plate is slidably connected to the surface of the blocking block. When the I-shaped plate is inserted into the inner wall of the groove plate, the C-shaped plate is stuck in the inner wall of the I-shaped plate to ensure the stable clamping of the I-shaped plate and avoid the loosening and dropping of the device caused by unstable connection. At the same time, after the I-shaped plate enters the groove plate, the blocking block drives the blocking block to move by the restoring force of the second spring, which can thus play a limiting role on the I-shaped plate.

[0006] For example, in a household combustible gas detector provided by at least one embodiment of the present disclosure, the collection device includes a filter barrel, a transmission rod, a transmission wheel 1, a rotating rod, a gas detector, and a fixed frame. The filter barrel is rotatably connected to the inner wall of the annular plate, the transmission rod is rotatably connected to the bottom of the I-shaped plate, the transmission wheel 1 is fixedly connected to the bottom of the transmission rod, and the rotating rod is rotatably connected to the top of the transmission wheel 1. After the I-shaped plate enters the interior of the groove plate, the water inlet pipe will be sealed and docked with the pipeline. At this time, the motor is started, and the motor drives the transmission wheel 2 to rotate, so that the dust on the surface of the filter barrel can be cleaned to prevent the dust from clogging the filter hole and affecting the detection function of the device. After the cleaning plate comes into contact with the filter barrel, it will swing and drive the rotating rod to rotate, so as to prevent the cleaning plate from damaging the filter barrel. The gas detector is fixedly connected At the bottom of the I-shaped plate, the fixed frame is fixedly connected to the inner wall of the filter barrel, and the collecting device also includes a fan assembly, a cleaning plate, a pipeline, a motor, and a second transmission wheel. The fan assembly is fixedly connected to the surface of the fixed frame, the cleaning plate is fixedly connected to the circumferential surface of the rotating rod, the pipeline is fixedly connected to the inner wall of the I-shaped plate, the motor is fixedly connected to the bottom of the I-shaped plate, and the second transmission wheel is fixedly connected to the output end of the motor. The circumferential surface of the filter barrel contacts the circumferential surface of the first transmission wheel, the circumferential surface of the filter barrel contacts the surface of the cleaning plate, and the inner wall of the filter barrel contacts the circumferential surface of the second transmission wheel. At the same time, the rotation of the fan assembly will suck the smoke in the air into the surface of the gas detector, thereby enhancing the detection efficiency of the gas detector and the smoke in the air, thereby improving the detection efficiency of the gas detector.

[0007] For example, in a household combustible gas detector provided by at least one embodiment of the present disclosure, the spray device also includes a sleeve, a spray head, a bump one, and a bump two. The sleeve is fixedly connected to the surface of the connecting plate, the spray head is fixedly connected to the bottom of the sleeve, the bump one is fixedly connected to the top of the L-shaped plate, and the bump two is fixedly connected to the rear of the sliding block. The bottom of the L-shaped plate is in contact with the top of the filter plate, the circumferential surface of the pipe is in contact with the inner wall of the sleeve, and the surface of the bump one is in contact with the surface of the bump two. When the filter barrel rotates, the spray head is driven to rotate by the rotation of the sleeve, so that when a combustible gas leak is detected, the spray head can spray water, which can not only avoid fire in advance, but also have a good warning effect, reminding people to pay attention to the leakage of combustible gas. At the same time, the filter plate can move up and down while rotating, thereby increasing the spraying effect of the spray head, thereby enhancing the water spraying range of the spray head.

[0008] The beneficial effects of the embodiments of the present disclosure are: In the present disclosure, through the cooperative operation among the groove plate, I-beam plate, water inlet pipe, fixing device, fixing plate, spring one, C-shaped plate, spring two, blocking block, annular plate, and screw plate, during installation, the screw plate is fixed on the wall, and the water inlet pipe is docked to ensure the water inlet of the water inlet pipe. At this time, the I-beam plate is inserted into the inside of the groove plate, which can facilitate subsequent disassembly, repair, or replacement, improving the convenience and speed of device use. When the I-beam plate is inserted into the inner wall of the groove plate, the C-shaped plate is stuck on the inner wall of the I-beam plate, ensuring the stable clamping of the I-beam plate and avoiding the looseness and dropping of the device caused by unstable connection. At the same time, after the I-beam plate enters the inside of the groove plate, the blocking block is driven to move by the restoring force of spring two, which can thus limit the I-beam plate.

[0009] In the present disclosure, through the cooperative operation among the filter barrel, transmission rod, first transmission wheel, rotating rod, gas detector, fixing bracket, fan assembly, cleaning plate, pipeline, motor, and second transmission wheel, after the I-beam plate enters the inside of the groove plate, the water inlet pipe will be hermetically docked with the pipeline. At this time, the motor is started, and the motor drives the second transmission wheel to rotate, which can thus clean the dust on the surface of the filter barrel to avoid dust clogging the filter holes and further affecting the detection function of the device. After the cleaning plate comes into contact with the filter barrel, it will swing to drive the rotating rod to rotate automatically, avoiding damage to the filter barrel by the cleaning plate. At the same time, when the fan assembly rotates, it will inhale the smoke in the air onto the surface of the gas detector, enhancing the detection efficiency of the gas detector with the smoke in the air, thereby improving the detection efficiency of the gas detector.

[0010] In the present disclosure, through the cooperative operation among the circular plate, L-shaped plate, filter plate, connecting plate, sleeve, sprinkler head, first convex block, sliding block, and second convex block, when the filter barrel rotates, the sleeve rotates to drive the sprinkler head to rotate. Thus, when it is detected that combustible gas leaks, the sprinkler head can spray water, which can not only prevent a fire in advance but also have a good warning effect, reminding people to pay attention to the leakage of combustible gas. At the same time, when the filter plate rotates, it can move up and down reciprocally, which can thus increase the spraying effect of the sprinkler head and enhance the water spraying range of the sprinkler head.

[0019] Such as Figures 1 to 7As shown, it shows a household combustible gas detector in an embodiment of the present disclosure, including a groove plate 1. An I-shaped plate 2 is installed on the inner wall of the groove plate 1. A water inlet pipe 3 is fixedly connected to the inner wall of the groove plate 1. The bottom of the I-shaped plate 2 is fixedly connected to an annular plate 5. A screw plate 6 is fixedly connected to the left side of the groove plate 1. During installation, the screw plate 6 is fixed to the wall, and the water inlet pipe 3 is docked to ensure the water inlet of the water inlet pipe. At this time, the I-shaped plate 2 is inserted into the inside of the groove plate 1, which can facilitate subsequent disassembly, repair or replacement, improving the convenience and speed of the device use. A fixing device 4 is arranged on the inner wall of the groove plate 1. A collecting device 7 is arranged at the bottom of the annular plate 5. A spraying device 8 is arranged at the bottom of the collecting device 7; The fixing device 4 includes a first fixing plate 41, a first spring 42, a C-shaped plate 43, a second spring 44, and a blocking block 45. The first fixing plate 41 is fixedly connected to the inner wall of the groove plate 1. The first spring 42 is fixedly connected to the right side of the first fixing plate 41. The C-shaped plate 43 is fixedly connected to the right side of the first spring 42. The second spring 44 is fixedly connected to the bottom of the inner wall of the groove plate 1. The blocking block 45 is fixedly connected to the top of the second spring 44. The surface of the C-shaped plate 43 is in contact with the inner wall of the groove plate 1. The surface of the C-shaped plate 43 is in contact with the surface of the I-shaped plate 2. The inner wall of the groove plate 1 is slidably connected to the surface of the blocking block 45. At the same time, when the I-shaped plate 2 is inserted into the inner wall of the groove plate 1, the I-shaped plate 2 will contact the C-shaped plate 43. When contacting, the C-shaped plate 43 will be squeezed, causing the first spring 42 to be compressed, so that the C-shaped plate 43 contacts the surface of the I-shaped plate 2. After the I-shaped plate 2 completely enters the inside of the groove plate 1, the first spring 42 resets and drives the C-shaped plate 43 to move, so that the C-shaped plate 43 is stuck in the inner wall of the I-shaped plate 2, ensuring the stable clamping of the I-shaped plate 2 and avoiding the looseness and dropping of the device caused by unstable connection. At the same time, after the I-shaped plate 2 enters the inside of the groove plate 1, it will cause the blocking block 45 to press down. After the I-shaped plate 2 enters the inside of the groove plate 1, the blocking block 45 drives the blocking block 45 to move through the restoring force of the second spring 44, so as to play a limiting role on the I-shaped plate 2.

[0020] In some examples, during installation, the screw plate 6 is fixed to the wall, and the water inlet pipe 3 is connected to ensure water inlet of the water inlet pipe. At this time, the I-shaped plate 2 is inserted into the interior of the groove plate 1, so that subsequent disassembly, maintenance or replacement can be facilitated, and the convenience and speed of using the device are improved. At the same time, when the I-shaped plate 2 is inserted into the inner wall of the groove plate 1, the I-shaped plate 2 will contact with the C-shaped plate 43. When in contact, the C-shaped plate 43 will be squeezed to cause the spring 42 to be compressed, so that the C-shaped plate 43 contacts the surface of the I-shaped plate 2. After the plate 2 completely enters the interior of the groove plate 1, the spring 1 42 resets and drives the C-shaped plate 43 to move, so that the C-shaped plate 43 is stuck on the inner wall of the I-shaped plate 2, ensuring the stability of the I-shaped plate 2 and avoiding the loosening and falling of the device caused by the unstable connection. At the same time, after the I-shaped plate 2 enters the interior of the groove plate 1, the blocking block 45 will be pressed down. After the I-shaped plate 2 enters the interior of the groove plate 1, the blocking block 45 is driven to move by the reset force of the spring 2 44, thereby limiting the I-shaped plate 2.

[0021] For example, Figures 1 to 7As shown, the collection device 7 includes a filter barrel 71, a transmission rod 72, a first transmission wheel 73, a rotating rod 74, a gas detector 75, and a fixing bracket 76. The filter barrel 71 is rotatably connected to the inner wall of the annular plate 5. The transmission rod 72 is rotatably connected to the bottom of the I-shaped plate 2. The first transmission wheel 73 is fixedly connected to the bottom of the transmission rod 72. The rotating rod 74 is rotatably connected to the top of the first transmission wheel 73. The gas detector 75 is fixedly connected to the bottom of the I-shaped plate 2. The fixing bracket 76 is fixedly connected to the inner wall of the filter barrel 71. The collection device 7 further includes a fan assembly 77, a cleaning plate 78, a pipeline 79, a motor 710, and a second transmission wheel 711. The fan assembly 77 is fixedly connected to the surface of the fixing bracket 76. The cleaning plate 78 is fixedly connected to the circumferential surface of the rotating rod 74. After the I-shaped plate 2 enters the inside of the groove plate 1, the water inlet pipe 3 will be hermetically docked with the pipeline 79. At this time, the motor 710 is started. The motor 710 drives the second transmission wheel 711 to rotate. The rotation of the second transmission wheel 711 drives the filter barrel 71 to rotate through friction. The rotation of the filter barrel 71 drives the first transmission wheel 73 to rotate through friction. The rotation of the first transmission wheel 73 drives the transmission rod 72 to rotate. The rotation of the first transmission wheel 73 drives the rotating rod 74 to rotate. The rotation of the rotating rod 74 drives the cleaning plate 78 to rotate, so as to clean the dust on the surface of the filter barrel 71 and prevent the dust from blocking the filter holes, thereby affecting the detection function of the device. After the cleaning plate 78 comes into contact with the filter barrel 71, it will swing and drive the rotating rod 74 to rotate self, avoiding damage to the filter barrel 71 by the cleaning plate 78. The pipeline 79 is fixedly connected to the inner wall of the I-shaped plate 2. The motor 710 is fixedly connected to the bottom of the I-shaped plate 2. The second transmission wheel 711 is fixedly connected to the output end of the motor 710. The circumferential surface of the filter barrel 71 is in contact with the circumferential surface of the first transmission wheel 73. The circumferential surface of the filter barrel 71 is in contact with the surface of the cleaning plate 78. The inner wall of the filter barrel 71 is in contact with the circumferential surface of the second transmission wheel 711. At the same time, the rotation of the filter barrel 71 drives the fixing bracket 76 to rotate. The rotation of the fixing bracket 76 drives the fan assembly 77 to rotate. The rotation of the fan assembly 77 will suck the smoke in the air onto the surface of the gas detector 75, enhancing the detection efficiency of the gas detector 75 with the smoke in the air, thereby improving the detection efficiency of the gas detector 75.

[0022] As Figures 1 to 7As shown, it shows that the spraying device 8 in another embodiment of the present disclosure includes a circular plate 81, an L-shaped plate 82, a filter plate 83, a connecting plate 84, and a sliding block 88. The circular plate 81 is fixedly connected to the circumferential surface of the pipeline 79. The L-shaped plate 82 is fixedly connected to the bottom of the circular plate 81. The sliding block 88 is slidably connected to the inner wall of the filter barrel 71. The filter plate 83 is fixedly connected to the rear of the sliding block 88. The connecting plate 84 is fixedly connected to the inner wall of the filter plate 83. The spraying device 8 further includes a sleeve 85, a spray head 86, a first convex block 87, and a second convex block 89. The sleeve 85 is fixedly connected to the surface of the connecting plate 84. The spray head 86 is fixedly connected to the bottom of the sleeve 85. When the filter barrel 71 rotates, the rotation of the filter barrel 71 drives the sliding block 88 to rotate. The rotation of the sliding block 88 drives the second convex block 89 to rotate. The rotation of the sliding block 88 drives the filter plate 83 to rotate. The rotation of the filter plate 83 drives the connecting plate 84 to rotate. The rotation of the connecting plate 84 drives the sleeve 85 to rotate. The rotation of the sleeve 85 drives the spray head 86 to rotate. Thus, when a combustible gas leak is detected, the spray head 86 can spray water, which can not only prevent a fire in advance but also have a good warning effect, reminding people to pay attention to the leakage of combustible gas. The first convex block 87 is fixedly connected to the top of the L-shaped plate 82. The second convex block 89 is fixedly connected to the rear of the sliding block 88. The bottom of the L-shaped plate 82 is in contact with the top of the filter plate 83. The circumferential surface of the pipeline 79 is in contact with the inner wall of the sleeve 85. The surface of the first convex block 87 is in contact with the surface of the second convex block 89. At the same time, when the second convex block 89 rotates, it will contact the first convex block 87, causing the second convex block 89 to move upward, thereby driving the sliding block 88 to move. The movement of the sliding block 88 drives the filter plate 83 to reciprocate up and down, so that the filter plate 83 can reciprocate up and down while rotating, thereby increasing the spraying effect of the spray head 86 and enhancing the water spraying range of the spray head 86. For example, as Figures 1 to 7As shown, after the I-shaped plate 2 enters the inside of the groove plate 1, the water inlet pipe 3 will be hermetically docked with the pipeline 79. At this time, the motor 710 starts, and the motor 710 drives the second transmission wheel 711 to rotate. The rotation of the second transmission wheel 711 drives the filter barrel 71 to rotate through friction. The rotation of the filter barrel 71 drives the first transmission wheel 73 to rotate through friction. The rotation of the first transmission wheel 73 drives the transmission rod 72 to rotate, and the rotation of the first transmission wheel 73 drives the rotating rod 74 to rotate. The rotation of the rotating rod 74 drives the cleaning plate 78 to rotate, so that the dust on the surface of the filter barrel 71 can be cleaned to avoid dust clogging the filter holes, thereby affecting the detection function of the device. After the cleaning plate 78 comes into contact with the filter barrel 71, it will swing to drive the rotating rod 74 to rotate itself, avoiding damage to the filter barrel 71 by the cleaning plate 78. At the same time, the rotation of the filter barrel 71 drives the fixed frame 76 to rotate, and the rotation of the fixed frame 76 drives the fan assembly 77 to rotate. The rotation of the fan assembly 77 will suck the smoke in the air onto the surface of the gas detector 75, enhancing the detection efficiency of the gas detector 75 and the smoke in the air, thereby improving the detection efficiency of the gas detector 75.

[0023] When the filter barrel 71 rotates, the rotation of the filter barrel 71 drives the sliding block 88 to rotate. The rotation of the sliding block 88 drives the second convex block 89 to rotate. The rotation of the sliding block 88 drives the filter plate 83 to rotate. The rotation of the filter plate 83 drives the connecting plate 84 to rotate. The rotation of the connecting plate 84 drives the sleeve 85 to rotate. The rotation of the sleeve 85 drives the spray head 86 to rotate. Thus, when a combustible gas leak is detected, the spray head 86 can spray water, which can not only prevent a fire in advance but also have a good warning effect, reminding people to pay attention to the leakage of combustible gas. At the same time, when the second convex block 89 rotates, it will contact the first convex block 87, causing the second convex block 89 to move upward, thereby driving the sliding block 88 to move. The movement of the sliding block 88 drives the filter plate 83 to move up and down reciprocally, so that the filter plate 83 can move up and down reciprocally while rotating, thereby increasing the spraying effect of the spray head 86 and enhancing the water spraying range of the spray head 86.
