The control ends of the second motor and the ventilation fan are both electrically connected to an intelligent control display, ensuring the ventilability of the device and thus promptly discharging any leaked non-toxic gases to prevent combustion or explosion.
[0013] The control method for this conveyor cabinet:
[0014] Step 1: Place the gas cylinder body. The user opens the cabinet door using the smart lock. At this point, the intersection of the two sets of auxiliary positioning lights indicates the placement position of the gas cylinder body. After moving the gas cylinder body to the intersection, the first motor, worm gear, and worm wheel enable the transmission rod, support rod, and connecting rod to rotate. Simultaneously, the first electric push rod extends the connecting rod until the clamp at one end of the fixing head is on both sides of the gas cylinder body. By rotating the threaded fixing rod, the clamp can fix the gas cylinder body. Then, control the output end of the first motor to rotate in the opposite direction. At this point, the worm gear, worm wheel, transmission rod, support rod, connecting rod, and fixing head can lift the gas cylinder body and insert it into the cabinet.
[0015] Step 2: Fixing. The second electric actuator makes the support plate fit tightly against the bottom of the gas cylinder body, which can also fix and support the gas cylinder body.
[0016] Step 3: Sealing. The dual-axis motor drives the two sets of first threaded rods to rotate. The first threaded rods and threaded sleeves enable the movable plates to move towards each other simultaneously until the movable plates are tightly fitted to the outer wall of the gas cylinder body. At this time, the two sets of movable plates are also tightly fitted.
[0017] Step 4: If the gas cylinder contains toxic or corrosive gas, the user removes the placement box using the handle, places a suitable reaction purifier inside the box, connects the connecting pipe assembly to the gas cylinder, and then closes the cabinet door. At this point, the upper and middle parts of the cabinet are sealed. After installation, the circulating fan allows the gas inside the top of the fixed sealing plate to circulate internally. The first intelligent detection sensor monitors the gas in the upper and middle parts of the cabinet in real time, and the second intelligent detection sensor can also monitor for leaks. When a gas leak occurs, the first and second intelligent detection sensors can control the intelligent control display to issue an alarm, thereby reminding the user to close the solenoid valve at the connection between the connecting pipe assembly and the gas cylinder through the intelligent control display, cutting off the gas supply. The leaked gas is then reacted with the reaction purifier through internal circulation, thereby reducing the content of the leaked gas.
[0018] Step 5: If the gas cylinder body contains flammable gas, the movable plate does not need to be closed, thus keeping the interior of the cabinet as a whole. At the same time, the arc-shaped sealing plate is opened by the second motor and the second threaded rod, ensuring that the air inside the cabinet can flow. The ventilation fan can increase the speed of air exchange between the inside and outside of the cabinet, and the second intelligent detection sensor can also effectively detect gas leaks.
[0019] Compared with the prior art, the beneficial effects of the present invention are:
[0020] When using this device, the user opens the cabinet door via the smart lock. The intersection of the two sets of auxiliary positioning lights indicates the placement position of the gas cylinder body. After moving the gas cylinder body to this intersection, the first motor, worm gear, and worm wheel cause the transmission rod, support rod, and connecting rod to rotate. Simultaneously, the first electric actuator extends the connecting rod until the clamp at one end of the fixing head is positioned on both sides of the gas cylinder body. The limiting groove limits the rotation trajectory of the support rod. When the support rod moves and engages with the inner wall of the limiting groove, the user rotates the threaded fixing rod to secure the gas cylinder body with the clamp. Then, the user controls the output end of the first motor to rotate in the reverse direction. At this point, the worm gear, worm wheel, transmission rod, support rod, connecting rod, and fixing head secure the gas cylinder... The main body is lifted, and because the clamps hold the top of the gas cylinder body, while the connecting rod and the fixing head are connected by a pivot, the gas cylinder body remains in a vertical position. When the support rod drives the connecting rod, fixing head, and gas cylinder body to reset and enter the cabinet, the first electric actuator allows one end of the connecting rod to retract into the support rod. After the support rod resets, the central axis of the gas cylinder body is also at the center of the weighted base. The user then controls the second electric actuator to ensure a tight fit between the support plate and the bottom of the gas cylinder body, simultaneously fixing and supporting the gas cylinder body. Because the worm gear and worm wheel are self-locking, they prevent the support rod, connecting rod, and gas cylinder body from shaking. Then, a dual-axis motor drives two sets of... The rotation of the first threaded rod, through the first threaded rod and the threaded sleeve, allows the movable plates to move simultaneously towards each other until the movable plates are tightly fitted against the outer wall of the gas cylinder body. At this point, both sets of movable plates are also tightly fitted. The user needs to select the appropriate program according to the characteristics of the gas inside the gas cylinder body. If the gas inside the gas cylinder body contains toxic or corrosive gas, the user can pull down one end of the handle to disengage the fixing block from the slot. At this point, the placement box can be removed, and a suitable reaction purifier can be placed inside the placement box. Then, after connecting the connecting pipe assembly to the gas cylinder body, the cabinet door is closed. At this point, the upper and middle parts of the cabinet are sealed. After installation, the circulating fan allows the internal gas at the top of the fixed sealing plate to circulate internally, thereby... The system can monitor the gas in the upper part of the cabinet in real time through a first intelligent detection sensor, and can also monitor for leaks through a second intelligent detection sensor. When a gas leak occurs, the first and second intelligent detection sensors can control the intelligent control display to issue an alarm, thereby alerting the user. At the same time, the intelligent control display closes the solenoid valve at the connection between the connecting pipe assembly and the gas cylinder body, cutting off the gas supply. Simultaneously, the leaked gas is circulated internally to react with the reaction purifier, thereby reducing the content of the leaked gas and improving user safety by preventing the leaked gas from being released into the room. If the gas cylinder body contains flammable gas, the movable plate does not need to be closed, thus keeping the interior of the cabinet as a whole.Simultaneously, the second motor and second threaded rod open the arc-shaped sealing plate, ensuring airflow within the cabinet. A ventilation fan further enhances the exchange rate between the internal and external air, improving safety. A second intelligent detection sensor effectively detects gas leaks, further enhancing safety. In the event of a power outage, a backup battery provides continued power, preventing malfunction. The device automatically moves the gas cylinder into the cabinet, reducing user workload and simplifying operation. It also selects appropriate programs for different gases, increasing usability and versatility, and offering diverse usage options. Attached Figure Description

[0031] 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.
[0032] Please see Figures 1-9 One embodiment provided by the present invention:
[0033] A special gas intelligent safety delivery cabinet and its control method are disclosed. The delivery cabinet includes a cabinet body 1, a cabinet door 2 connected to one side of the cabinet body 1 via a pivot, an intelligent control display 4 installed at the top of the cabinet body 1, first ventilation openings 5 at the bottom of both sides of the cabinet body 1, a second ventilation opening 6 at the back of the cabinet body 1, a weighted base 9 fixedly connected to the bottom of the cabinet body 1, a gas cylinder body 8 located at the top of the weighted base 9 inside the cabinet body 1, a connecting pipe assembly 7 connected to the gas cylinder body 8 connected to the upper middle part of the cabinet body 1, a spare battery 10 installed on one side of the weighted base 9, an auxiliary mechanism for moving the gas cylinder body 8 installed in the lower middle part of the cabinet body 1, and an intelligent control mechanism for circulation purification, detection, and ventilation installed in the upper middle part of the cabinet body 1.
[0034] Please see Figures 2-5In this embodiment, the auxiliary mechanism includes a limiting groove 11. Limiting grooves 11 are provided at both ends of the weighted base 9. Two sets of support rods 12 are provided at the top of the weighted base 9. A connecting rod 13 is slidably connected to the top of each support rod 12. A fixing head 14 is connected to the top of each connecting rod 13 via a rotating shaft. A clamp 15 is slidably connected to the ends of the fixing heads 14 that are close to each other. A threaded fixing rod 16 is threadedly connected to the middle of each fixing head 14, and one end of each threaded fixing rod 16 is threadedly connected to one end of the clamp 15. A first electric push rod 17, which is fixedly connected to the connecting rod 13, is provided inside each support rod 12. An auxiliary positioning light 18 is symmetrically arranged on one side of the weighted base 9. A transmission line is provided on one side of the middle of the weighted base 9. The center of the weighted base 9 is rotatably connected to a transmission rod 20, which is fixedly connected to the bottom end of the support rod 12. A worm gear 21 is fixedly connected to the center of the transmission rod 20, and the worm gear 21 is located inside the transmission groove 19. A first motor 22 is installed inside the transmission groove 19. The output end of the first motor 22 is fixedly connected to a worm 23 that meshes with the worm gear 21. One end of the worm 23 is fixedly connected to the inner wall of the transmission groove 19 through a bearing, which facilitates the user to move the gas cylinder body 8 into the cabinet 1 and improves the user's safety. A groove 24 is opened in the center of the weighted base 9. A second electric push rod 25 is installed inside the bottom end of the groove 24. A support plate 26 is slidably connected to the center of the weighted base 9, and the bottom end of the support plate 26 is connected to the second electric push rod. The output end of motor 25 is fixedly connected. The user opens cabinet door 2 through smart lock 3. At this time, the intersection of the two sets of auxiliary positioning lights 18 is the placement position of the gas cylinder body 8. After the user moves the gas cylinder body 8 to the intersection, the output end of the first motor 22 drives the worm gear 23 to rotate. The worm gear 23 drives the worm wheel 21 and the transmission rod 20 to rotate. The transmission rod 20 drives the support rod 12 and the connecting rod 13 to rotate. At the same time, the first electric push rod 17 can extend the connecting rod 13 until the clamp 15 at one end of the fixed head 14 is on both sides of the gas cylinder body 8. The rotation trajectory of the support rod 12 can be limited by the limiting groove 11. When the support rod 12 moves and fits against the inner wall of the limiting groove 11, the support rod 12 and the connecting rod 13 move to the maximum position. When the user rotates the threaded fixing rod 16, the clamp 15 moves closer to the gas cylinder body 8 until the gas cylinder body 8 is fixed. Then, the output end of the first motor 22 is controlled to rotate in the reverse direction. At this time, the transmission rod 20 is rotated through the worm gear 23 and worm wheel 21. The transmission rod 20 drives the support rod 12, connecting rod 13 and fixing head 14 to reset. At this time, the gas cylinder body 8 is lifted by the support rod 12 and connecting rod 13. Since the clamp 15 clamps the top of the gas cylinder body 8, and the connecting rod 13 and fixing head 14 are connected by a rotating shaft, the gas cylinder body 8 is always in a vertical state. The support rod 12 drives the connecting rod 13, fixing head 14 and gas cylinder body 8 to reset and enter the interior of the cabinet 1. At the same time, the output end of the first electric push rod 17 shortens.This allows one end of the connecting rod 13 to retract into the support rod 12. After the support rod 12 is reset, the central axis of the gas cylinder body 8 is also at the center of the weighted base 9. The user then controls the second electric actuator 25 to operate, extending its output end. This allows the support plate 26 to fit tightly against the bottom of the gas cylinder body 8, simultaneously fixing and supporting the gas cylinder body 8. Because the worm gear 23 and worm wheel 21 are self-locking, they prevent the support rod 12, connecting rod 13, and gas cylinder body 8 from shaking, thus providing support and fixation for the gas cylinder body 8.
[0035] Please see Figure 6 and Figure 7 In this embodiment, the intelligent control mechanism includes a sealing mechanism, a circulation purification mechanism, and a ventilation mechanism. The sealing mechanism includes a fixed sealing plate 27, which is fixedly connected to the middle of the cabinet 1. Movable plates 28 are provided at both ends of the fixed sealing plate 27, and the ends of the movable plates 28 that are close to each other are arc-shaped. The arcs at one end of each movable plate 28 fit against the gas cylinder body 8. Three sets of sliders 29 are symmetrically slidably connected to the bottom of the fixed sealing plate 27, and each slider 29 is fixedly connected to the movable plate 28. A dual-axis motor 30 is provided in the middle of the fixed sealing plate 27, and the output end of the dual-axis motor 30 is fixedly connected to the inner wall of the cabinet 1 via a bearing. The first threaded rod 31 is connected to the first threaded rod 31. The ends of the first threaded rod 31 that are close to each other are connected to the threaded sleeves 32 that are fixedly connected to the movable plate 28. The control end of the dual-axis motor 30 is electrically connected to the intelligent control display 4. The output end of the dual-axis motor 30 drives the two sets of first threaded rods 31 to rotate. The rotation of the first threaded rod 31 can drive the threaded sleeves 32 to move. The threaded sleeves 32 can make the movable plate 28 move towards the ends that are close to each other at the same time until the movable plate 28 is tightly fitted with the outer wall of the gas cylinder body 8. At this time, the two sets of movable plates 28 are also tightly fitted, which makes it convenient for users to change the appropriate program according to different gases and improves the applicability of this device.
[0036] Please see Figures 6-8In this embodiment, the circulating purification mechanism includes a circulator 33. The circulator 33 is fixedly connected to the upper middle part of the cabinet 1, and the bottom end of the circulator 33 is fixedly connected to the fixed sealing plate 27. Circulating air vents 34 are provided at both ends of the circulator 33. Circulating fans 35 are provided at the top of both sides of the circulator 33. A first intelligent detection sensor 36 is provided at the bottom of each circulating fan 35 and is fixedly connected to the inner wall of the circulator 33. A second intelligent detection sensor 37 is provided on the inner wall of the top of the circulator 33, and the second intelligent detection sensor 37 is located directly above the gas cylinder body 8. A placement box 38 is slidably connected to the top of the circulator 33. A reaction purifier 39 is provided inside the placement box 38. One end of the circulator 33 is symmetrically fixed with a handle 40, and one side of the handle 40 is located at the bottom of the circulator 33. Two sets of latching slots 41 are provided on the surface of the middle part of the circulator 33. Each latching slot 41 contains a fixing block 42 fixedly connected to the handle 40, and one end of each fixing block 42 is beveled. The control terminals of the circulating fan 35, the first intelligent detection sensor 36, and the second intelligent detection sensor 37 are all electrically connected to the intelligent control display 4. If the gas cylinder body 8 contains toxic or corrosive gas, the upper part of the cabinet 1 needs to be sealed to allow internal air circulation for purification. The user can disengage the fixing block 42 from the latching slot 41 by pulling down one end of the handle 40. Then, the placement box 38 can be removed, and a suitable reaction purifier 39 can be placed inside the placement box 38. This is then placed inside the circulator 33. After connecting the connecting pipe assembly 7 to the gas cylinder body 8, the cabinet door 2 is closed. At this point, the upper and middle parts of the cabinet 1 are sealed. After installation, the circulation fan 35 starts, and the air at the top of the fixed sealing plate 27 enters the circulator 33 through the circulation vent 34 at one end. The circulation fan 35 provides the power for air circulation, passing through the reaction purifier 39 inside the placement box 38, and finally exiting through the circulation vent 34 at the other end of the circulator 33, thus forming an internal air circulation. The first intelligent detection sensor 36 monitors the air in the upper and middle parts of the cabinet 1. The system performs real-time monitoring of the gas cylinder, and can also monitor for leaks via the second intelligent detection sensor 37. When a gas leak occurs, the first intelligent detection sensor 36 and the second intelligent detection sensor 37 can control the intelligent control display 4 to issue an alarm, thereby alerting the user. At the same time, the intelligent control display 4 closes the solenoid valve at the connection between the connecting pipe assembly 7 and the gas cylinder body 8, cutting off the gas supply. Simultaneously, the leaked gas is circulated internally to react with the reaction purifier 39, thereby reducing the content of the leaked gas and improving the safety of the user. This prevents a large amount of leaked gas from being released into the room. The system can automatically circulate and purify the gas, and can also automatically issue a leak alarm to promptly remind the user.
[0037] Please see Figure 2 and Figure 9In this embodiment, the ventilation mechanism includes a sealing block 43. The sealing block 43 is fixedly connected inside the cabinet 1 and is located at the connection between the connecting pipe assembly 7 and the gas cylinder body 8. A receiving groove 44 is formed inside the sealing block 43, and an arc-shaped sealing plate 45 is symmetrically slidably connected inside the receiving groove 44. A second threaded rod 46 is connected to the inner wall of the receiving groove 44 via a bearing, and the second threaded rod 46 is connected to the arc-shaped sealing plate 45 via threads. A second motor 47 is provided at one end of the sealing block 43, and the output end of the second motor 47 is fixedly connected to the second threaded rod 46. A ventilation fan 48 is provided in the middle of the sealing block 43. The control terminals of both the second motor 47 and the ventilation fan 48 are electrically connected to the intelligent control display 4. If the gas cylinder body 8 contains combustible gas... At this time, the movable plate 28 does not need to be closed, so that the interior of the cabinet 1 is in a whole. The output end of the second motor 47 drives the second threaded rod 46 to rotate. The rotating second threaded rod 46 can separate the two sets of arc sealing plates 45, so that the arc sealing plates 45 can be opened by the second motor 47 and the second threaded rod 46, ensuring that the air inside the cabinet 1 can flow. At the same time, the ventilation fan 48 can increase the speed of air exchange between the air inside the cabinet 1 and the outside air, thereby improving the safety of the device. At the same time, the second intelligent detection sensor 37 can also effectively detect gas leaks, further improving the safety of the device and ensuring the breathability of the device, so as to discharge the leaked non-toxic gases in time and avoid combustion or explosion.
[0038] It should be noted that a smart lock 3 is installed in the middle of the cabinet door 2, and one end of the smart lock 3 is fixedly connected to the cabinet body 1. A solenoid valve is installed at the connection between the connecting pipe assembly 7 and the gas cylinder body 8. The control terminal of the smart control display 4 is electrically connected to the external power supply and the backup battery 10. The control terminals of the smart lock 3 and the solenoid valve are both electrically connected to the smart control display 4 to facilitate automatic control of the device. The bottom ends of the support rods 12 are located inside the limiting grooves 11. The ends of the clamps 15 that are close to each other are all arc-shaped, and one end of the clamps 15 is in contact with the surface of the gas cylinder body 8. The control terminals of the first electric push rod 17, the auxiliary positioning light 18, the first motor 22 and the second electric push rod 25 are all electrically connected to the smart control display 4 to facilitate the operation of the device and also improve the sealing performance.
[0039] The control method for this conveyor cabinet:
[0040] Step 1: Place the gas cylinder body 8. The user opens the cabinet door 2 using the smart lock 3. At this time, the intersection of the two sets of auxiliary positioning lights 18 is the placement position of the gas cylinder body 8. After moving the gas cylinder body 8 to the intersection, the transmission rod 20, support rod 12, and connecting rod 13 can be rotated by the first motor 22, worm gear 23, and worm wheel 21. At the same time, the connecting rod 13 is extended by the first electric push rod 17 until the clamp 15 at one end of the fixing head 14 is on both sides of the gas cylinder body 8. By rotating the threaded fixing rod 16, the clamp 15 can fix the gas cylinder body 8. Then, control the output end of the first motor 22 to rotate in the opposite direction. At this time, the gas cylinder body 8 can be lifted and inserted into the cabinet 1 by the worm gear 23, worm wheel 21, transmission rod 20, support rod 12, connecting rod 13, and fixing head 14.
[0041] Step 2: Fixing. The second electric push rod 25 makes the support plate 26 fit tightly against the bottom of the gas cylinder body 8, which can also fix and support the gas cylinder body 8.
[0042] Step 3: Sealing. The dual-axis motor 30 drives the two sets of first threaded rods 31 to rotate. The first threaded rods 31 and the threaded sleeve 32 enable the movable plate 28 to move towards one end of each other at the same time until the movable plate 28 is tightly attached to the outer wall of the gas cylinder body 8. At this time, the two sets of movable plates 28 are also tightly attached.
[0043] Step 4: If the gas cylinder body 8 contains toxic or corrosive gas, the user removes the placement box 38 using handle 40, places a suitable reaction purifier 39 inside the placement box 38, connects the connecting pipe assembly 7 to the gas cylinder body 8, and then closes the cabinet door 2. At this time, the upper and middle parts of the cabinet body 1 are sealed. After installation, the circulating fan 35 enables the internal gas at the top of the fixed sealing plate 27 to circulate internally. The first intelligent detection sensor 36 monitors the gas in the upper and middle parts of the cabinet body 1 in real time, and the second intelligent detection sensor 37 can also monitor for leaks. When a gas leak occurs, the first intelligent detection sensor 36 and the second intelligent detection sensor 37 can control the intelligent control display 4 to issue an alarm, thereby reminding the user. The user then closes the solenoid valve at the connection between the connecting pipe assembly 7 and the gas cylinder body 8 through the intelligent control display 4, cutting off the gas supply. The leaked gas reacts with the reaction purifier 39 through internal circulation, thereby reducing the content of the leaked gas.
[0044] Step 5: If the gas cylinder body 8 contains flammable gas, the movable plate 28 does not need to be closed, thus keeping the interior of the cabinet 1 as a whole. At the same time, the arc sealing plate 45 is opened by the second motor 47 and the second threaded rod 46, ensuring that the air inside the cabinet 1 can flow. The ventilation fan 48 can increase the speed of air exchange between the inside of the cabinet 1 and the outside air. The second intelligent detection sensor 37 can also effectively detect gas leaks.
[0045] When the user uses this device, the user opens the cabinet door 2 via the smart lock 3. At this time, the intersection of the two sets of auxiliary positioning lights 18 is the placement position of the gas cylinder body 8. After the user moves the gas cylinder body 8 to the intersection, the output end of the first motor 22 drives the worm gear 23 to rotate. The worm gear 23 drives the worm wheel 21 and the transmission rod 20 to rotate. The transmission rod 20 drives the support rod 12 and the connecting rod 13 to rotate. At the same time, the first electric push rod 17 can extend the connecting rod 13 until the clamp 15 at one end of the fixing head 14 is on both sides of the gas cylinder body 8. The rotation trajectory of the support rod 12 can be limited by the limiting groove 11. When the support rod 12 moves and fits against the inner wall of the limiting groove 11, the support rod 12 and the connecting rod 13 move to their maximum position. Rotating the threaded fixing rod 16 allows the clamp 15 to move closer to the gas cylinder body 8 until the gas cylinder body 8 is fixed. Then, the output end of the first motor 22 is controlled to rotate in the reverse direction. At this time, the transmission rod 20 is rotated through the worm 23 and worm wheel 21. The transmission rod 20 drives the support rod 12, connecting rod 13, and fixing head 14 to reset. At this time, the gas cylinder body 8 is lifted by the support rod 12 and connecting rod 13. Since the clamp 15 clamps the top of the gas cylinder body 8, and the connecting rod 13 and fixing head 14 are connected by a rotating shaft, the gas cylinder body 8 is always in a vertical state. The support rod 12 drives the connecting rod 13, fixing head 14, and gas cylinder body 8 to reset and enter the interior of the cabinet 1. At the same time, the output end of the first electric push rod 17 shortens, thereby enabling the connecting rod 12 to rotate. One end of the connecting rod 13 retracts into the support rod 12. After the support rod 12 is reset, the central axis of the gas cylinder body 8 is also at the center of the weighted base 9. The user then controls the second electric actuator 25 to work. The output end of the second electric actuator 25 extends, allowing the support plate 26 to fit tightly against the bottom of the gas cylinder body 8. This also fixes and supports the gas cylinder body 8. Since the worm gear 23 and worm wheel 21 are self-locking, they can prevent the support rod 12, connecting rod 13, and gas cylinder body 8 from shaking. The output end of the dual-axis motor 30 drives the two sets of first threaded rods 31 to rotate. The rotation of the first threaded rods 31 drives the threaded sleeve 32 to move. The threaded sleeve 32 allows the movable plate 28 to move towards one end of each other simultaneously. Move the movable plate 28 until it is tightly fitted against the outer wall of the gas cylinder body 8. At this point, both sets of movable plates 28 are also tightly fitted. The user needs to select the appropriate program according to the characteristics of the gas inside the gas cylinder body 8. If the gas inside the gas cylinder body 8 is toxic or corrosive, the upper part of the cabinet 1 needs to be sealed to allow the internal air to circulate for purification. The user can pull down one end of the handle 40 to disengage the fixing block 42 from the latch 41. At this point, the placement box 38 can be removed. Place a suitable reaction purifier 39 inside the placement box 38, and then place it inside the circulator 33. After connecting the connecting pipe assembly 7 to the gas cylinder body 8, close the cabinet door 2. At this point, the upper middle part of the cabinet 1 is sealed. After installation,When the circulating fan 35 starts, the air at the top of the fixed sealing plate 27 enters the circulator 33 through the circulating air outlet 34 at one end of the circulator 33. Powered by the circulating fan 35, the air circulates through the reaction purifier 39 inside the placement box 38 and finally exits through the circulating air outlet 34 at the other end of the circulator 33, thus forming an internal air circulation. The first intelligent detection sensor 36 monitors the gas in the upper part of the cabinet 1 in real time, while the second intelligent detection sensor 37 monitors for leaks. When a gas leak occurs, the first and second intelligent detection sensors 36 and 37 control the intelligent control display 4 to issue an alarm, alerting the user. Simultaneously, the intelligent control display 4 closes the solenoid valve at the connection between the connecting pipe assembly 7 and the gas cylinder body 8, cutting off the gas supply. The leaked gas is then reacted with the reaction purifier 39 through internal circulation, reducing the content of the leaked gas and improving user safety by preventing large amounts of leaked gas from being released into the room. If the gas cylinder body 8 contains flammable gas, the movable plate 28... Without needing to be closed, the interior of cabinet 1 remains a single unit. The output of the second motor 47 drives the second threaded rod 46 to rotate. The rotating threaded rod 46 separates the two sets of arc-shaped sealing plates 45, allowing the arc-shaped sealing plates 45 to open via the second motor 47 and the second threaded rod 46. This ensures airflow within cabinet 1. Simultaneously, the ventilation fan 48 increases the speed of air exchange between the inside and outside of cabinet 1, thereby improving the safety of the device. The second intelligent detection sensor 37 effectively detects gas leaks, further enhancing safety. In the event of a power outage, the backup battery 10 continues to provide power, preventing the device from becoming unusable due to power failure. The device automatically moves the gas cylinder body 8 into the cabinet 1, reducing user workload and simplifying operation. Furthermore, the device can select appropriate programs based on different gases, further improving user convenience and increasing its applicability, reducing limitations and providing diverse options for users.
