Description

Technical Field

[0001] This utility model relates to the field of monitoring technology, and in particular to a gas monitoring device based on MEMS sensors. Background Technology

[0002] By integrating gas-sensitive elements onto tiny chips using MEMS technology, MEMS sensors can react physically or chemically with target gases, causing changes in the electrical properties of the elements. These changes are converted into electrical signals, which are then amplified and filtered by signal processing circuits. After analysis and calculation by a microprocessor, information such as the type and concentration of the target gas can be obtained. By monitoring the concentration of flammable and explosive gases such as combustible gases, the occurrence of dangerous accidents such as gas explosions can be prevented.

[0003] Gas monitoring devices employing MEMS sensors mainly consist of a main housing, which houses the MEMS sensor, microcontroller, power module, communication module, alarm module, and display module. The MEMS sensor converts gas concentration information into an electrical signal through the interaction of gas and a sensitive material. This electrical signal is processed by a signal conditioning circuit and outputs a standard signal. The microcontroller determines whether the concentration exceeds the limit based on a preset algorithm and threshold, and executes corresponding actions. The power module provides power to ensure stable operation. The alarm module emits audible and visual alarms when the concentration exceeds the limit, and the display module presents real-time gas concentration information. Additionally, pipe interfaces are located on the left and right sides of the housing, connecting to external pipe joints. To prevent gas leakage at these joints, some monitoring devices incorporate clamping structures to enhance sealing. However, because these clamping structures are assembled using threaded connections, they can loosen after a period of use, leading to a decrease in sealing performance and affecting the stability of the monitoring device. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a gas monitoring device based on MEMS sensors to overcome the shortcomings of existing devices.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a gas monitoring device based on a MEMS sensor, including a main unit, a base at the bottom of the main unit, connectors fixedly provided at the left and right ends of the base, nuts sleeved on the outside of the connectors, and the nuts threadedly connected to the connectors;

[0006] Multiple rubber clamps are provided on the side of the connector away from the base. Each rubber clamp is evenly arranged in the circumferential direction of the connector axis. External threads are provided on the outer side of the rubber clamps, and the connector is threaded to the external threads.

[0007] The front of the main unit is equipped with a cover plate. One end of the cover plate is hinged to a pivot located at the bottom of the main unit, and the other end of the cover plate is engaged with the base. The left and right sides of the cover plate are equipped with baffles to restrict the movement of the nut.

[0008] A further improvement is that the main unit has a control panel on the front, which includes touch buttons and a digital screen.

[0009] A further improvement is that the cover plate is equipped with a glass plate and a rubber button, with the rubber button positioned directly above the touch button and the glass plate positioned directly above the digital screen.

[0010] A further improvement is that the bottom of the baffle has a groove that movably engages with the connector. When the cover is placed on the main unit, the cover will engage with the base, and the groove on the baffle will engage with the connector.

[0011] A further improvement is that: the inner side of the cover plate is provided with multiple spherical buckles, which are fixedly connected to the cover plate; the front of the base body is provided with multiple spherical slots, which engage with the spherical buckles.

[0012] Further improvements include: the inner side of the cover plate is provided with an elastic buckle, which is fixedly connected to the cover plate; the front of the base is provided with a slot; a hook groove is provided on the side of the base away from the main unit, which is connected to the slot; the elastic buckle is slidably connected to the slot; and a hook is provided at the end of the slot, which engages with the hook groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] After the external pipe fitting is connected to the connector via threads, turning the nut on the outside of the connector will cause each rubber clamp to converge toward its center, ensuring that the pipe fitting will not loosen. After the cover plate is placed on the front of the main unit, the baffle will be locked in the gap between the base and the nut and hold the nut in place, further improving the firmness of the connection between the monitoring device and the pipeline.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a gas monitoring device based on a MEMS sensor, including a host 1, a base 4 at the bottom of the host 1, connectors 8 fixedly provided at the left and right ends of the base 4, nuts 82 sleeved on the outside of the connectors 8, and the nuts 82 threadedly connected to the connectors 8.

[0022] Multiple rubber clamps 81 are provided on the side of the connector 8 away from the base 4. Each rubber clamp 81 is evenly arranged in the circumferential direction of the axis of the connector 8. External threads 83 are provided on the outer side of the rubber clamps 81, and the connector 8 is threadedly connected to the external threads 83.

[0023] After the external pipe fitting is connected to the connector 8 via threads, the nut 82 on the outside of the connector 8 is rotated. After the nut 82 is rotated from the outside of the connector 8 to the outside of the rubber clamp 81, the nut 82 will squeeze each rubber clamp 81, causing each rubber clamp 81 to converge toward its center. During the convergence, the rubber clamp 81 squeezes the external pipe fitting, ensuring that the pipe fitting will not loosen.

[0024] When the rubber clamp 81 is tightened, it applies a reaction force to the nut 82 to improve the stability of the connection. A cover plate 2 is provided on the front of the main unit 1. One end of the cover plate 2 is hinged to a pivot 3 located at the bottom of the main unit 1, and the other end is engaged with the base 4. Baffles 23 are provided on the left and right sides of the cover plate 2 to restrict the movement of the nut 82. When the cover plate 2 is closed on the front of the main unit 1, the baffles 23 on both sides of the cover plate 2 will engage in the gap between the base 4 and the nut 82. By holding the nut 82 in place, the baffles 23 ensure that the nut 82 will not loosen due to the compression of the rubber clamp 81, further improving the secure connection between the monitoring device and the pipeline.

[0025] In addition to limiting the nut 82 through the baffle 23, the cover plate 2 can also protect the main unit 1. Specifically, the main unit 1 has a control panel on the front, which includes touch buttons 11 and a digital screen 12.

[0026] The cover plate 2 is provided with a glass plate 21 and a rubber button 22. The rubber button 22 is located directly above the touch button 11, and the glass plate 21 is located directly above the digital screen 12.

[0027] The cover 2 effectively blocks dust and moisture, preventing short circuits and corrosion caused by dust accumulation or moisture intrusion, thus extending the service life of the control panel. The glass plate 21 corresponds to the digital screen 12 on the control panel, allowing operators to clearly see the content on the digital screen 12, such as equipment operating status and parameter settings, without the cover 2 affecting information reading. The rubber button 22 has a certain degree of elasticity, which can buffer and absorb shock when pressed, reducing the impact on the touch buttons 11 on the control panel and helping to extend the service life of the touch buttons 11.

[0028] In a preferred embodiment, the bottom of the baffle 23 has a groove that movably engages with the connector 8. When the cover 2 is placed on the main unit 1, the cover 2 engages with the base 4, and the groove on the baffle 23 engages with the connector 8.

[0029] Regarding the connection between cover plate 2 and base 4, please refer to the following instructions:

[0030] The inner side of the cover plate 2 is provided with multiple spherical buckles 6, which are fixedly connected to the cover plate 2. The front of the base body 4 is provided with multiple spherical slots 7, which engage with the spherical buckles 6. After the cover plate 2 is lowered, the spherical buckles 6 on the inner side of the cover plate 2 will engage with the spherical slots 7 on the base body 4. The spherical slots 7, by cooperating with the spherical buckles 6, limit the cover plate 2 and ensure that the cover plate 2 will not detach from the base body 4.

[0031] Furthermore, the inner side of the cover plate 2 is provided with an elastic buckle 5, which is fixedly connected to the cover plate 2. The front of the base body 4 is provided with a slot 51, and the side of the base body 4 away from the main unit 1 is provided with a hook groove 52, which communicates with the slot 51. The elastic buckle 5 is slidably connected to the slot 51, and the end of the slot 51 is provided with a hook 53, which engages with the hook groove 52. When the cover plate 2 is lowered, the spherical buckle 6 engages in the spherical slot 7, and the elastic buckle 5 fixed on the inner side of the cover plate 2 also inserts into the slot 51. The hook 53 at the end of the slot 51 then engages in the hook groove 52, further limiting the cover plate 2. To open, use your finger to push the hook groove 52 out of the hook 53 and lift the cover plate 2 upwards.

[0032] How this application works:

[0033] After the external pipe fitting is connected to the connector 8 via threads, the nut 82 on the outside of the connector 8 is rotated. Once the nut 82 is screwed from the outside of the connector 8 to the outside of the rubber clamps 81, the nut 82 will compress each rubber clamp 81, causing them to converge towards the center. This convergence of the rubber clamps 81 compresses the external pipe fitting, ensuring it does not loosen. When the cover plate 2 is closed on the front of the main unit 1, the baffles 23 on both sides of the cover plate 2 will lock into the gap between the base 4 and the nut 82. The baffles 23 prevent the nut 82 from loosening by holding it in place, further improving the stability of the connection between the monitoring device and the pipeline.
