Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0038] Example 1

[0039] A household smart safety fireproof gas meter, such as Figures 1-11 As shown, it includes a housing 1, a movable plate 2, a gas display meter 3, a gas pipe 4, a water pipe 6, a closing assembly 7, a fire extinguishing assembly 8, and a pushing assembly 9. The movable plate 2 is rotatably mounted on the upper front side of the housing 1. The gas display meter 3 is installed on the lower side of the housing 1. The gas pipe 4 is symmetrically arranged between the gas display meter 3 and the housing 1. The water pipe 6 is located on the upper side of the inside of the housing 1 and passes through the housing 1. The closing assembly 7 is located between the upper side of the inside of the housing 1 and the inner side of the gas pipe 4. The fire extinguishing assembly 8 is located between the lower side of the gas display meter 3 and the water pipe 6. The pushing assembly 9 is located in the middle of the upper side of the inside of the housing 1.

[0040] The closing assembly 7 includes a gas sensor 701, a first support block 702, a first electric push rod 703, a pressing rod 704, a valve block 705, and a rotating rod 706. The gas sensor 701 is located in the middle of the top of the gas display meter 3. The gas sensor 701 is located on the lower side inside the housing 1. The first support block 702 is located on the upper side inside the housing 1. The first electric push rod 703 is located inside the first support block 702. The telescopic rod of the first electric push rod 703 is connected to the pressing rod 704. The valve blocks 705 are rotatably located inside the gas pipes 4. The rotating rod 706 is located between the inner sides of the valve blocks 705. The rotating rod 706 is rotatably connected to the pressing rod 704.

[0041] People install this gas meter on the wall, connecting the left gas pipe 4 to the gas supply, the right gas pipe 4 to the gas cylinder, and the water pipe 6 to the water source. Then, they press the main power switch to supply power to the gas meter. During the gas supply process through gas pipe 4, if a gas leak occurs, the gas sensor 701 detects the leak and sends a signal. Upon receiving the signal, the control module controls the first electric push rod 703 to extend for one second and then close. The extension of the first electric push rod 703 causes the pressing rod 704 to move downwards, which in turn causes the rotating rod 706 and the valve block 705 to rotate clockwise, causing the valve block 705 to close the gas pipe 4. At this point, the gas pipe 4 stops supplying gas, achieving the effect of closing the gas pipe 4. Then people... To address gas leaks, manually rotate the movable plate 2 to open it. Gas usage can be observed through the gas display meter 3. Once the gas leak stops and dissipates, manually rotate the movable plate 2 to close it. At this point, the gas sensor 701, which no longer detects gas, sends a signal. Upon receiving the signal, the control module controls the first electric push rod 703 to shorten its extension rod by one second before closing it. The shortening of the first electric push rod 703 causes the pressing rod 704 to move upwards, which in turn causes the rotating rod 706 and valve block 705 to rotate in opposite directions. This prevents the valve block 705 from blocking the gas pipe 4, allowing the gas pipe 4 to continue supplying gas. When the gas meter is no longer needed, simply press the main power switch to disconnect the power.

[0042] The fire extinguishing assembly 8 includes a temperature sensor 801, a solenoid valve 802, a telescopic pipe 803, and a nozzle 804. The temperature sensor 801 is located in the middle of the bottom of the gas display meter 3. The solenoid valve 802 is located on the lower side of the water pipe 6. The telescopic pipes 803 are symmetrically arranged on the upper side inside the outer casing 1. The inner sides of the telescopic pipes 803 are connected to the water pipe 6 through pipes. Each telescopic pipe 803 has a nozzle 804 on its front side. The nozzle 804 cooperates with the movable plate 2.

[0043] The launching component 9 includes a second support block 901, a second electric push rod 902, a third electric push rod 903, a first support rod 904, a guide rod 905, and a first push rod 906. The second support block 901 is located on the upper side inside the outer casing 1. The second electric push rod 902 is located on the left side of the second support block 901, and the third electric push rod 903 is located on the right side of the second support block 901. The first support rod 904 is symmetrically arranged on the left and right sides of the upper front side inside the outer casing 1. The guide rod 905 is slidably provided on the lower inner side of the first support rod 904. The first push rod 906 is located between the front sides of the guide rod 905. The first push rod 906 is connected to the nozzle 804 and is connected to the telescopic rods of the second electric push rod 902 and the third electric push rod 903.

[0044] Temperature sensor 801 has a first preset value and a second preset value, with the first preset value being larger than the second preset value. In the event of a fire, as the temperature gradually rises, the temperature difference between the indoor temperature and the temperature sensor 801 reaches the first preset value. Upon receiving this signal, the control module energizes the solenoid valve 802. Simultaneously, the control module controls the extension rods of the second electric push rod 902 and the third electric push rod 903 to extend for one second and then close. The extension of the extension rods of the second and third electric push rods 902 and 903 drives the first push rod 906, guide rod 905, and nozzle 804 forward, stretching the telescopic tube 803. The nozzle 804 moves forward and contacts the movable plate 2, causing the movable plate 2 to rotate forward and open. At this time, the solenoid valve 802 is energized, opening the valve inside the solenoid valve 802 and allowing water to flow into the water pipe 6. The water is then delivered to the nozzle 804 via the telescopic tube 803, causing the nozzle 804 to spray water to extinguish the fire. After the fire is extinguished, the temperature gradually decreases. When the temperature value between the indoor temperature and the temperature sensor 801 reaches the second preset value of the temperature sensor 801, the temperature sensor 801 sends a signal. After receiving the signal, the control module controls the solenoid valve 802 to be de-energized and stop working. At the same time, the control module controls the telescopic rods of the second electric push rod 902 and the third electric push rod 903 to shorten for 1 second and then close. After the telescopic rods of the second electric push rod 902 and the third electric push rod 903 are shortened, they drive the first push rod 906, the guide rod 905 and the nozzle 804 to move backward and reset, causing the telescopic tube 803 to retract and the nozzle 804 to move away from the movable plate 2. People can manually rotate the movable plate 2 in the opposite direction to close it. After the solenoid valve 802 is de-energized, the valve inside the solenoid valve 802 is closed, and the nozzle 804 will no longer spray water.

[0045] Example 2

[0046] Based on Example 1, such as Figures 12-19As shown, it also includes an alarm component 10, which includes a second support rod 1001, a first slide rod 1002, a pulley 1003, a third support rod 1004, a second slide rod 1005, a first spring 1006, a steel wire rope 1007, an alarm button 1008, and a buzzer 1009. Two second support rods 1001 are symmetrically arranged on the upper side inside the housing 1. A first slide rod 1002 is slidably arranged between the two second support rods 1001 on the same side. A first push rod 906 cooperates with the first slide rod 1002. A pulley 1003 is symmetrically arranged on the upper rear side inside the housing 1. A third support rod 1004 is symmetrically arranged in the middle of the part. A second slide rod 1005 is slidably arranged between the lower sides of the third support rod 1004. A first spring 1006 is provided between the second slide rod 1005 and the third support rod 1004. The first spring 1006 is sleeved on the third support rod 1004. A steel wire rope 1007 is connected between the second slide rod 1005 and the first slide rod 1002. The steel wire rope 1007 is wound on the pulley 1003. An alarm button 1008 is provided in the middle of the rear side of the inner shell 1. The second slide rod 1005 cooperates with the alarm button 1008. A buzzer 1009 is provided on the front side of the movable plate 2.

[0047] It also includes an intake assembly 11, which includes a third support block 1101, a distance sensor 1102 and a fan 1103. The third support block 1101 is located on the lower rear side inside the housing 1, the distance sensor 1102 is located on the top of the third support block 1101, and the fan 1103 is rotatably located on the lower front side of the housing 1.

[0048] The distance sensor 1102 is equipped with a first preset value and a second preset value. The value of the first preset value is greater than the value of the second preset value. When the first push rod 906 moves forward, it contacts the first slide rod 1002, causing the slide rod 1002 to move forward and pull the wire rope 1007 in the positive direction, causing the pulley 1003 to rotate in the positive direction. Under the action of the wire rope 1007, the second slide rod 1005 moves upward, compressing the first spring 1006. The upward movement of the second slide rod 1005 presses the alarm button 1. 008. Alarm button 1008 sends a signal. After receiving the signal, the control module controls the buzzer 1009 to power on, causing the buzzer 1009 to sound an alarm, thus serving its alarm function and reminding people to take fire prevention measures. When the second slide bar 1005 moves upward away from the distance sensor 1102, the distance between the second slide bar 1005 and the distance sensor 1102 reaches the first preset value of the distance sensor 1102. The distance sensor 1102 then sends a signal, and the control module receives the signal to power on the fan 1103. The operation causes the fan 1103 to rotate, rapidly drawing gas into the housing 1, allowing the gas sensor 701 to quickly detect the gas and thus quickly shut off the gas pipe 4. When the first push rod 906 moves backward away from the first slide rod 1002, the first spring 1006 resets, causing the second slide rod 1005 to move downward, pulling the steel wire rope 1007 in the opposite direction, causing the pulley 1003 to rotate in the opposite direction, which in turn causes the first slide rod 1002 to move backward and reset, and the second slide rod 1005 to move downward away from the alarm button 1. 008, alarm button 1008 sends a signal, the control module controls the buzzer 1009 to power off and stop working, so that the buzzer 1009 does not make a sound. At the same time, the second slide bar 1005 moves down and approaches the distance sensor 1102. After the distance between the second slide bar 1005 and the distance sensor 1102 reaches the second preset value of the distance sensor 1102, the distance sensor 1102 sends a signal. After receiving the signal, the control module controls the fan 1103 to power off and stop working, so that the fan 1103 returns to its original state.

[0049] It also includes an indicator component 12, which includes a fourth support rod 1201, a top rod 1202, a second spring 1203, a fifth support rod 1204, and an indicator light 1205. The fourth support rod 1201 is provided on the upper front side of the inner shell 1. The top rod 1202 is slidably provided on the fourth support rod 1201. The rotating rod 706 cooperates with the top rod 1202. The second spring 1203 is provided between the top rod 1202 and the fourth support rod 1201. The second spring 1203 is sleeved on the fourth support rod 1201. The fifth support rod 1204 is symmetrically provided on the left and right sides of the upper middle side of the inner shell 1. The indicator light 1205 is slidably provided between the lower sides of the fifth support rod 1204. The indicator light 1205 is slidably connected to the outer shell 1.

[0050] When the rotating rod 706 rotates clockwise, it contacts the top rod 1202, causing the top rod 1202 to move upward. The second spring 1203 is compressed. Simultaneously, when the gas sensor 701 detects gas, it sends a signal. After receiving the signal, the control module controls the indicator light 1205 to power on, causing the indicator light 1205 to emit light. The top rod 1202 moves upward and contacts the indicator light 1205, causing the indicator light 1205 to move upward, placing it above the outer casing 1. This achieves the function of alerting people to gas leaks and preventing fire accidents. When the gas sensor 701 does not detect gas, it sends a signal. After receiving the signal, the control module controls the indicator light 1205 to de-energize and stop working, so that the indicator light 1205 does not emit light. When the rotating rod 706 rotates in the opposite direction away from the top rod 1202, the second spring 1203 resets, causing the top rod 1202 to move downward away from the indicator light 1205. Due to the gravity of the indicator light 1205, the indicator light 1205 will automatically move downward and reset.

[0051] It also includes a control box 5, which is located on the upper front side of the outer casing 1. The control box 5 contains a switching power supply, a power module, and a control module. The switching power supply powers the gas meter, and its output terminal is electrically connected to the power module. The power module is connected to the main power switch via a circuit. The control module and the power module are electrically connected. The control module is connected to a DS1302 clock circuit and a 24C02 circuit. The alarm button 1008, gas sensor 701, temperature sensor 801, distance sensor 1102, buzzer 1009, and indicator light 1205 are all electrically connected to the control module. The first electric push rod 703, the second electric push rod 902, the third electric push rod 903, the solenoid valve 802, and the fan 1103 are all connected to the control module via external circuits.
