Description

Technical Field

[0001] This invention belongs to the technical field of gas alarm equipment, specifically an intelligent gas alarm switch. Background Technology

[0002] A gas alarm device is a detector that detects the concentration of gas. Its core component is a gas-sensitive sensor, which is installed in places where gas leaks may occur. When the concentration of gas in the air exceeds the set value, the detector will be triggered to sound an alarm and send out an audible and visual alarm signal. At the same time, it will shut off the gas shut-off solenoid valve, thus preventing accidents even in unoccupied environments.

[0003] In order to intuitively observe the gas concentration and flexibly control the opening and closing of the gas valve, a gas alarm switch is usually used to control the solenoid valve. This alarm switch can remotely control and provide feedback on the status of the gas pipeline, which can effectively improve the safety of daily gas use.

[0004] However, currently, when installing alarm switch control panels, double-sided tape or other adhesive materials are usually used to stick the control panel to the wall. Although this installation method is simple, some adhesive material will remain on the wall after the control panel is removed. In places where gas is used, there will be a lot of oil fumes. At this time, the oil fumes will stick to the adhesive material, causing the material to accumulate on the wall. If bolts are used for fixing, the dust generated when drilling will pollute the indoor environment and damage the wall. Therefore, this method needs to be improved and optimized. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent gas alarm switch to solve the problems mentioned in the background art.

[0008] Sealing grooves are fixedly installed on both the left and right sides of the rear wall of the mounting housing. One end of the moving rod passes through the interior of the sealing groove and is fixedly connected to the piston. A sealing lip is fixedly installed on the rear side of the sealing groove, and the sealing lip fits tightly against the wall surface.

[0009] Preferably, there are two sets of combustible gas sensors, both of which are fixedly installed inside the fixed housing, and one end of each set of fixed housings is fixedly provided with a connecting wire. The two sets of combustible gas sensors, the intelligent control panel, and the intelligent solenoid valve are connected to each other through the connecting wire.

[0010] A top plate is movably installed inside the fixed shell. The top plate and the inner wall of the fixed shell are elastically connected by a spring. A filter screen is detachably installed inside the fixed shell. The filter screen is located outside the combustible gas sensor. Two sets of fixing plates are fixedly installed at the rear end of the filter screen. The fixing plates are located between the top plate and the inner wall of the fixed shell. A positioning groove is fixedly opened on one side of the fixed shell.

[0011] Preferably, the left and right outer walls of the mounting housing are fixedly provided with sliding grooves, and a pressure rod is movably installed inside the sliding groove. The top of the pressure rod and the inner wall of the sliding groove are elastically connected by a spring. The top of the control rod is provided with a slot for the pressure rod to be inserted.

[0012] Preferably, a power supply is fixedly installed inside the mounting housing, and a power interface is provided at the bottom of the mounting housing. The power supply provides power for the operation of the intelligent control panel, and the movable compartment is located on the left and right sides of the power supply.

[0013] Preferably, a groove is provided on the right side wall of the mounting housing, and a connecting wire is fixedly connected to the back of the intelligent control panel. One end of the connecting wire passes through the groove and the mounting housing and is fixedly connected to the combustible gas sensor.

[0014] Preferably, each of the two sets of slides has a vertical groove on one side, and a control plate is movably installed inside the vertical groove. One end of the control plate is fixedly connected to the pressure rod.

[0015] Preferably, two sets of fixing rods are fixedly installed on the inner wall of the front side of the fixing shell, and the fixing plate has holes for the fixing rods to move inside. One end of the fixing rod passes through the interior of the fixing plate to fix the filter screen.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This invention uses the pulling of control rods on both sides to rotate the transmission wheel. The transmission wheel, through the teeth on the surface of the moving rod, drives the moving rod to move linearly forward along the movable chamber. Further, the piston extracts the air from the sealing lip, making the sealing lip and the wall tightly fit together. Compared with traditional devices, this device achieves non-destructive installation of the intelligent control panel by making the sealing lip fit with the wall and extracting the air from the sealing lip, avoiding the residue of sticky substances. Furthermore, the installation of the housing and the wall is convenient and flexible, improving user satisfaction with the product.

[0019] 2. This invention utilizes the elastic potential energy of spring one to push the top plate against the filter screen, causing the fixing rod to be inserted into the fixing plate for fixation. By pressing and rotating the filter screen, it can be pulled out from the fixing shell. Compared with traditional devices, this device uses pressing and rotating the filter screen to complete the disassembly and installation, effectively improving the efficiency of filter screen cleaning and replacement, further protecting the combustible gas sensor from oil fume pollution, and extending the service life of the combustible gas sensor.

[0020] 3. After the outer casing is installed, the elastic potential energy of the second spring pushes the rod downward and inserts it into the slot, thereby fixing the control rod. Compared with traditional devices, this device uses the second spring to fix the control rod, effectively ensuring the stability of the outer casing and preventing the outer casing and intelligent control panel from falling off.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, this embodiment of the invention provides an intelligent gas alarm switch, including a mounting housing 1, an intelligent control panel 2, an intelligent solenoid valve 3, a gas valve 4, and a combustible gas sensor 5. The intelligent control panel 2 is rotatably mounted on the front end of the mounting housing 1. The gas outlet pipes of the intelligent solenoid valve 3 and the gas valve 4 are interconnected. One end of the intelligent control panel 2 and the intelligent solenoid valve 3 are both connected to the combustible gas sensor 5.

[0032] Control slots 7 are provided on both the left and right sides of the mounting housing 1. A rotating rod 9 is rotatably installed inside the control slot 7. A drive ring 11 is fixedly sleeved in the middle of the rotating rod 9. A control rod 10 is fixedly installed on the outer wall of the rotating rod 9. Movable chambers 8 are fixedly installed on the inner walls of both the left and right sides of the mounting housing 1. A moving rod 13 is movably installed inside the movable chamber 8. A transmission wheel 12 is rotatably installed on one side of the moving rod 13. One end of the transmission wheel 12 is connected to the drive ring 11, and the other end of the transmission wheel 12 is connected to the moving rod 13 through teeth 14.

[0033] Sealing grooves 15 are fixedly installed on both the left and right sides of the rear wall of the housing 1. One end of the moving rod 13 passes through the interior of the sealing groove 15 and is fixedly connected to the piston 16. A sealing lip 17 is fixedly installed on the rear side of the sealing groove 15, and the sealing lip 17 fits tightly against the wall.

[0034] When gas leak detection or intelligent control of gas on / off is required, the user needs to install the device first. First, the user connects the outlets of the intelligent solenoid valve 3 and the gas valve 4. After connection, the user connects the intelligent solenoid valve 3 to the power supply. Then, the user determines the installation location of the intelligent control panel 2 and wipes the installation location smooth. Next, the user attaches the back of the mounting housing 1 to the wall, ensuring the sealing lip 17 contacts the wall. Then, the user holds and pulls the control levers 10 on both sides, causing the rotating rod 9 to rotate. The rotating rod 9 drives the drive ring 11 to rotate, further rotating the transmission wheel 12. Through the teeth 14 on the surface of the moving rod 13, the moving rod 13 is driven to move linearly forward along the movable chamber 8. As the moving rod 13 moves, the piston 16 moves forward along the sealing groove 15, drawing air out between the sealing lip 17 and the wall, thus sealing the gas. The lip 17 fits tightly against the wall, securing the smart control panel 2. The user then lifts the control plate 31 upwards with their thumb, causing the pressure rod 28 to retract into the groove 29 and compressing the spring 30. When the control rod 10 reaches its foremost position, the user releases the control plate 31. The elastic potential energy of the spring 30 drives the pressure rod 28 downwards, inserting it into the slot 27, thus securing the control rod 10 and ensuring the mounting housing 1 is firmly fixed. The user then flips the smart control panel 2 upwards and connects the connecting wire 19 to it, passing one end of the connecting wire 19 through the groove 18 and positioning it on the outer wall of the mounting housing 1. The user then fixes the mounting housing 20 1.5 meters away from the gas stove and connects the power supply 6, enabling the combustible gas sensor 5 to begin detection. The smart control panel 2 and the smart solenoid valve 3 are interconnected and work together via a Wi-Fi wireless communication module, enabling real-time detection and display of gas concentration, one-button gas switching, timed cyclic control, and remote control via an app.

[0035] Pulling the control levers 10 on both sides causes the transmission wheel 12 to rotate. The transmission wheel 12 drives the moving rod 13 to move linearly forward along the movable chamber 8 through the teeth 14 on the surface of the moving rod 13. The piston 16 further extracts the air from the sealing lip 17, making the sealing lip 17 fit tightly against the wall. Compared with the traditional device, this device completes the non-destructive installation of the intelligent control panel 2 by fitting the sealing lip 17 against the wall and extracting the air from the sealing lip 17, avoiding the residue of sticky substances. In addition, the installation of the housing 1 and the wall is convenient and flexible, improving user satisfaction with the product.

[0036] There are two sets of combustible gas sensors 5, both of which are fixedly installed inside the fixed housing 20. One end of each of the two fixed housings 20 is fixedly provided with a connecting line 19. The two sets of combustible gas sensors 5, the intelligent control panel 2, and the intelligent solenoid valve 3 are connected to each other through the connecting line 19.

[0037] A top plate 22 is movably installed inside the fixed housing 20. The top plate 22 and the inner wall of the fixed housing 20 are elastically connected by a spring 21. A filter screen 25 is detachably installed inside the fixed housing 20. The filter screen 25 is located outside the combustible gas sensor 5. Two sets of fixing plates 26 are fixedly installed at the rear end of the filter screen 25. The fixing plates 26 are located between the top plate 22 and the inner wall of the fixed housing 20.

[0038] During prolonged testing, the filter 25 filters out oil fumes from the air to ensure the lifespan of the combustible gas sensor 5. However, due to the presence of oil fumes in the testing environment, the filtration efficiency of the filter 25 may decrease. In this case, the user presses down on the filter 25, causing the top plate 22 to be compressed and the fixing rod 23 to disengage from the interior of the fixing plate 26. The user can then rotate the filter 25. When the fixing plate 26 is observed to be at the bottom of the positioning groove 24, the user can remove the filter 25 for replacement or cleaning. After cleaning, the user aligns the fixing plate 26 with the positioning groove 24 and presses it down. Then, the user rotates the fixing plate 26 so that it is positioned below the fixing rod 23. Subsequently, the user releases the filter 25. Through the elastic potential energy of the spring 21, the top plate 22 pushes the filter 25, causing the fixing rod 23 to insert into the interior of the fixing plate 26, completing the installation.

[0039] Using the elastic potential energy of spring 21, top plate 22 pushes filter screen 25, causing fixing rod 23 to be inserted into fixing plate 26 for fixation. By pressing and rotating filter screen 25, filter screen 25 is pulled out from fixing shell 20. Compared with traditional devices, this device uses pressing and rotating filter screen 25 to complete the disassembly and installation of filter screen 25, effectively improving the efficiency of cleaning and replacing filter screen 25, further protecting combustible gas sensor 5 from oil fume pollution, and improving the service life of combustible gas sensor 5.

[0040] The outer walls of the housing 1 are fixedly provided with grooves 29. A pressure rod 28 is movably installed inside the groove 29. The top of the pressure rod 28 and the inner wall of the groove 29 are elastically connected by a spring 30. The top of the control rod 10 is provided with a slot 27 for the pressure rod 28 to be inserted.

[0041] The user lifts the control panel 31 upwards with their thumb. At this time, the pressure rod 28 is retracted into the slide groove 29, and the spring 30 is compressed. When the control rod 10 moves to the front end, the user releases the control panel 31. At this time, the elastic potential energy of the spring 30 will drive the pressure rod 28 downwards and insert it into the groove 27, thereby fixing the control rod 10 and ensuring that the housing 1 is firmly fixed.

[0042] After the housing 1 is installed, the elastic potential energy of the second spring 30 pushes the rod 28 downward and inserts it into the slot 27, thereby fixing the control rod 10. Compared with the traditional device, this device uses the second spring 30 to fix the rod 28 to fix the control rod 10, which effectively ensures the stability of the housing 1 and prevents the housing 1 and the intelligent control panel 2 from falling off.

[0043] The power supply 6 is fixedly installed inside the mounting shell 1, and a power interface is provided at the bottom of the mounting shell 1. The power supply 6 provides power for the operation of the intelligent control panel 2, and the movable compartment 8 is located on the left and right sides of the power supply 6.

[0044] The right side wall of the mounting housing 1 has a groove 18, and the back of the intelligent control panel 2 is fixedly connected to a connecting wire 19. One end of the connecting wire 19 passes through the groove 18 and the fixed housing 20, and is fixedly connected to the combustible gas sensor 5.

[0045] The connecting line 19 can transmit the concentration of external combustible gas detected by the combustible gas sensor 5 in real time.

[0046] Each of the two sets of slide grooves 29 has a vertical groove 32 on one side, and a control plate 31 is movably installed inside the vertical groove 32. One end of the control plate 31 is fixedly connected to the pressure rod 28.

[0047] The user lifts the control panel 31 upwards with their thumb, at which point the pressure rod 28 is retracted into the slide groove 29.

[0048] Two sets of fixing rods 23 are fixedly installed on the inner front wall of the fixing shell 20. The fixing plate 26 has holes for the fixing rods 23 to move. One end of the fixing rod 23 passes through the interior of the fixing plate 26 to fix the filter screen 25.

[0049] When the user releases the filter screen 25, the elastic potential energy of the spring 21 causes the top plate 22 to push the filter screen 25, causing the fixing rod 23 to be inserted into the fixing plate 26, thus completing the installation.

[0050] Both the intelligent solenoid valve 3 and the intelligent control panel 2 are equipped with WIFI communication modules, and the intelligent solenoid valve 3 and the intelligent control panel 2 communicate with each other via WIFI.

[0051] Working principle and usage process:

[0052] When gas leak detection or intelligent control of gas on / off is required, the user needs to install the device first. First, the user connects the outlets of the intelligent solenoid valve 3 and the gas valve 4. After connection, the user connects the intelligent solenoid valve 3 to the power supply. Then, the user determines the installation location of the intelligent control panel 2 and wipes the installation location smooth. Next, the user attaches the back of the mounting housing 1 to the wall, ensuring the sealing lip 17 contacts the wall. Then, the user holds and pulls the control levers 10 on both sides, causing the rotating rod 9 to rotate. The rotating rod 9 drives the drive ring 11 to rotate, further rotating the transmission wheel 12. Through the teeth 14 on the surface of the moving rod 13, the moving rod 13 is driven to move linearly forward along the movable chamber 8. As the moving rod 13 moves, the piston 16 moves forward along the sealing groove 15, drawing air out between the sealing lip 17 and the wall, thus sealing the gas. The lip 17 fits tightly against the wall, securing the smart control panel 2. The user then lifts the control plate 31 upwards with their thumb, causing the pressure rod 28 to retract into the groove 29 and compressing the spring 30. When the control rod 10 reaches its foremost position, the user releases the control plate 31. The elastic potential energy of the spring 30 drives the pressure rod 28 downwards, inserting it into the slot 27, thus securing the control rod 10 and ensuring the mounting housing 1 is firmly fixed. The user then flips the smart control panel 2 upwards and connects the connecting wire 19 to it, passing one end of the connecting wire 19 through the groove 18 and positioning it on the outer wall of the mounting housing 1. The user then fixes the mounting housing 20 1.5 meters away from the gas stove and connects the power supply 6, enabling the combustible gas sensor 5 to begin detection. The smart control panel 2 and the smart solenoid valve 3 are interconnected and work together via a Wi-Fi wireless communication module, enabling real-time detection and display of gas concentration, one-button gas switching, timed cyclic control, and remote control via an app.

[0053] During prolonged testing, the filter 25 filters out oil fumes from the air to ensure the lifespan of the combustible gas sensor 5. However, due to the presence of oil fumes in the testing environment, the filtration efficiency of the filter 25 may decrease. In this case, the user presses down on the filter 25, causing the top plate 22 to be compressed and the fixing rod 23 to disengage from the interior of the fixing plate 26. The user can then rotate the filter 25. When the fixing plate 26 is observed to be at the bottom of the positioning groove 24, the user can remove the filter 25 for replacement or cleaning. After cleaning, the user aligns the fixing plate 26 with the positioning groove 24 and presses it down. Then, the user rotates the fixing plate 26 so that it is positioned below the fixing rod 23. Subsequently, the user releases the filter 25. Through the elastic potential energy of the spring 21, the top plate 22 pushes the filter 25, causing the fixing rod 23 to insert into the interior of the fixing plate 26, completing the installation.
