[0018] Please see Figure 1-7 This utility model provides a technical solution: A gas monitoring device includes a sensor module 1, a control module 2, and an alarm module 3. The sensor module 1, control module 2, and alarm module 3 are all mounted on the cover of a gas cylinder storage box 4. An air inlet slot 5 is provided on one side of the gas cylinder storage box 4. An exhaust assembly 6 is installed on the top of the cover of the gas cylinder storage box 4, and a sealing assembly 7 for sealing the air inlet slot 5 is installed on the body of the gas cylinder storage box 4. The exhaust assembly 6 includes a fixed outer shell 61 fixedly connected to the top of the cover of the gas cylinder storage box 4. An exhaust pipe 62 is installed on the top of the fixed outer shell 61. A fan 63 is installed inside the fixed outer shell 61. A vertically arranged connecting shaft 64 is fixedly connected to the top of the fan 63. A fixed sector plate 65 is fixedly connected to the outside of the connecting shaft 64. A rotatable connection is provided above the fixed sector plate 65. The movable sector plate 66 has a corresponding groove 67 on the outer side of the fixed housing 61. The inner side of the groove 67 has a fixing block 68 that is fixedly connected to the movable sector plate 66. With the gas cylinder placement box 4 and the exhaust assembly 6, if there is a gas leak in the gas cylinder when the device is in use, the control module 2 can activate the alarm module 3 to start the alarm. When the operator handles the problem, first open the sealing assembly 7, then move the fixing block 68 to rotate the fixed sector plate 65, and then start the exhaust fan 63. After ventilation for a period of time, the operator can open the gas cylinder placement box 4 to inspect the leaking gas cylinder. This design can detect the gas cylinder in real time and allow the operator to easily and quickly discharge the gas in the gas cylinder placement box 4 when the gas cylinder leaks, so as to avoid the gas from affecting human health.

[0019] The sealing assembly 7 includes a fixed frame 71 fixedly connected to the outside of the gas cylinder storage box 4. A fixed plate 72 is provided on the inner side of the fixed frame 71. A sealing flexible plate 73 is fixedly connected to the side of the fixed plate 72 near the gas cylinder storage box 4. The side of the sealing flexible plate 73 near the gas cylinder storage box 4 is tightly fitted to the gas cylinder storage box 4. The design of the sealing assembly 7 makes sealing the gas cylinder storage box 4 simpler and facilitates quick operation by the user.

[0020] Multiple rubber pulleys 74 are rotatably connected inside the fixed frame 71. The outer side of the rubber pulleys 74 is tightly fitted with the fixed plate 72. The design of the rubber pulleys 74 enables the fixed plate 72 to move more smoothly and improves the efficiency of use.

[0021] The gas cylinder storage box 4 is equipped with a leak-proof component 8 to prevent gas from leaking out of the air inlet slot 5. The leak-proof component 8 can prevent gas leakage when the user opens the sealing component 7.

[0022] The leak-proof component 8 includes a connecting frame 81 fixedly connected to the inside of the gas cylinder storage box 4. An inclined elastic flexible plate 82 is fixedly connected to the inside of the connecting frame 81. The side of the elastic flexible plate 82 closest to the gas cylinder storage box 4 is tightly fitted to the gas cylinder storage box 4. Under normal circumstances, the elastic flexible plate 82 inside the connecting frame 81 can fit against the inside of the gas cylinder storage box 4, so that the gas inside the gas cylinder storage box 4 will not leak when the sealing component 7 is opened. When the exhaust fan 63 is working, due to the pressure generated by the gas, the elastic flexible plate 82 can deform upward, and the gas can flow through one side of the elastic flexible plate 82.

[0023] A support plate 83 is fixedly connected to the inner side of the connecting frame 81 below the flexible flexible plate 82, and a limiting plate 84 is fixedly connected to the inner side of the connecting frame 81 above the flexible flexible plate 82. The design of the support plate 83 and the limiting plate 84 can provide support and limit the flexible flexible plate 82, and prevent the flexible flexible plate 82 from being damaged due to excessive gas flow rate.

[0024] The gas cylinder storage box 4 has multiple adapters 9 corresponding to the gas cylinders on one side of the box cover. A label 10 is fixedly connected to the side of the box cover of the gas cylinder storage box 4 above the adapters 9. The design of the adapters 9 and the label 10 allows the operator to distinguish the gas type represented by each adapter 9 to prevent confusion. Even if a gas cylinder leaks, the gas cylinder storage box 4 can keep the gas inside and prevent it from leaking out.

[0025] Workflow: Before use, the device needs to be powered on and connected to an external controller. When using the device, multiple gas cylinders can be placed inside the gas cylinder storage box 4. Each gas cylinder is connected to the adapter 9 using a flexible hose, and the gas cylinder type is labeled on the label 10 above the adapter 9. Finally, close the gas cylinder storage box 4, and the device can be used normally. The design of the adapter 9 and label 10 allows operators to distinguish the gas type represented by each adapter 9, preventing confusion. Even if a gas cylinder leaks, the gas cylinder storage box 4 can keep the gas inside, preventing leakage. During device use, if a gas cylinder leaks, the sensor module 1 can detect the gas in time and send a signal to the control module 2. Block 2 activates the alarm module 3, alerting staff to take timely action. During this process, due to the high gas concentration inside the cylinder storage box 4, venting is necessary. The specific steps are as follows: First, place the exhaust pipe 62 outside the window or in the exhaust gas collection channel. Then, remove the fixing plate 72 from the inside of the fixing frame 71, allowing the sealing flexible plate 73 to detach from the cylinder storage box 4. During this process, the pulley slides on the surface of the fixing plate 72. After the fixing plate 72 is removed, the fixing block 68 inside the sliding groove 67 can be moved, causing the movable sector plate 66 above the fixed sector plate 65 to rotate outside the connecting shaft 64. Next, start the exhaust fan 63 inside the fixed housing 61. The exhaust fan 63 can vent the cylinder storage box 4. The air inside is extracted to create a negative pressure state. At this time, outside air can enter the gas cylinder storage box 4 through the air inlet slot 5 and be discharged through the fixed outer shell 61 and the exhaust pipe 62, thereby completing the rapid replacement of the gas inside the gas cylinder storage box 4. After a period of ventilation, the operator can open the gas cylinder storage box 4 to inspect the leaking gas cylinder. The design of the gas cylinder storage box 4, the exhaust component 6 and its connecting components can detect the gas cylinder in real time, and when the gas cylinder leaks, the operator can easily and quickly discharge the gas inside the gas cylinder storage box 4 to avoid the gas affecting human health. The design of the sealing component 7 makes the sealing of the gas cylinder storage box 4 simpler and easier for the user to operate quickly. The design of the rubber pulley 74 can make the fixed plate 72 The movement is smoother, improving efficiency. When the user opens the sealing component 7, the gas in the gas cylinder storage box 4 may be discharged through the air inlet slot 5. However, the leak-proof component 8 can prevent gas leakage at this time. Under normal circumstances, the elastic flexible plate 82 in the connecting frame 81 can fit against the inside of the gas cylinder storage box 4, so that the gas in the gas cylinder storage box 4 will not leak when the sealing component 7 is opened. When the exhaust fan 63 is working, the elastic flexible plate 82 can deform upward due to the pressure generated by the gas, and the gas can flow through one side of the elastic flexible plate 82. The design of the support plate 83 and the limiting plate 84 can provide support and limit for the elastic flexible plate 82, preventing the elastic flexible plate 82 from being damaged due to excessive gas flow rate.
