Description

Technical Field

[0001] This utility model relates to the field of laboratory air monitoring technology, specifically a laboratory air environment monitoring device. Background Technology

[0002] Laboratories are places where experiments are conducted and store many items needed for these experiments, some of which are hazardous materials. During experiments, toxic and harmful gases can easily be generated; therefore, monitoring the air quality in laboratories is essential.

[0003] A gas detector is an instrument specifically designed to detect gas concentrations. It can sensitively sense the presence and concentration changes of specific gases in the environment. In laboratory settings, its core function is to accurately detect toxic gases, such as carbon monoxide, hydrogen sulfide, and ammonia.

[0004] Existing gas detectors are mostly wall-mounted or fixedly installed on laboratory benches. Although they can detect gas concentrations in specific areas, they have the following problems: (1) This physical form and installation method greatly limits their flexibility. Gas detectors can only cover the area around the installation point and cannot be carried around. Once the experimenters need to leave the fixed installation location of the detector, such as when they move between different areas of a large laboratory to conduct experiments, or when they work at a temporarily added experimental site, they cannot perceive the gas risk in the movement path in real time, which poses a safety hazard. (2) The response of fixed detectors in the existing technology is delayed. When gas leaks, fixed gas detectors cannot provide an immediate warning in the area where people are active. They need to wait for the gas leak to spread to the detection point before triggering an alarm, which makes it difficult to provide timely warnings and affects the speed of emergency response. (3) Existing gas detectors do not integrate positioning and tracking functions. Laboratory managers cannot obtain the dynamic location of experimenters in real time, making it difficult to optimize the spatial layout or quickly locate personnel in emergency situations.

[0005] Therefore, there is an urgent need to develop a laboratory air monitoring device that combines wearability, real-time monitoring, and location tracking to solve the spatial and temporal limitations of fixed monitoring and the limited functionality of portable devices. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a laboratory air environment monitoring device that is easy to carry. It solves the problem that existing gas detectors are mostly wall-mounted or fixedly installed on laboratory benches, which makes them inconvenient to carry and leads to a serious lag in the perception of potential risks during critical operations.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a laboratory air environment monitoring device, comprising a gas detection device and an elastic band, characterized in that: the gas detection device is detachably connected to the elastic band via a connector;

[0008] The connector includes a fixed shell, a back plate, and an elastic snap-fit ​​assembly; a fixed shell is fixedly installed on one side of the elastic band, and a slot is provided on one side of the fixed shell; a back plate is fixedly installed on one side of the gas detection device, and an extended rod is provided on the side of the back plate away from the gas detection device, with a locking block at the end of the rod; the elastic snap-fit ​​assembly includes a telescopic rod, a spring, and a blocking block; telescopic rods are fixedly installed on the front and rear inner walls of the slot, and the blocking blocks are fixedly connected to the ends of each telescopic rod; a spring is sleeved on the outer surface of each telescopic rod.

[0009] The locking block and the blocking block achieve unidirectional locking through a mutually compatible inclined surface structure.

[0010] Furthermore, the elastic band is made of a spandex-nylon blend material, with Velcro at both ends forming a closed loop.

[0011] Furthermore, the card block is an isosceles trapezoid, and the two blocking blocks are right-angled trapezoids, with the same angle of inclination on their inclined surfaces.

[0012] Furthermore, a control rod is fixedly installed on the top of each of the two blocking blocks.

[0013] Furthermore, the top of the fixed shell has two openings that are adapted to the control lever to enable manual unlocking.

[0014] Furthermore, the gas detection device is internally equipped with a GPS module, a main control chip, a WIFI positioning module, and a wireless communication module, which are interconnected with the main control chip through a circuit system.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The elastic band of the laboratory air environment monitoring device has Velcro at both ends that can be adjusted according to the size of the experimenter's arm, making it easy to wear on the arm. After the gas detection device is connected to the elastic band through a connector, the experimenter can carry it at any time to continuously monitor the surrounding air environment. Whether moving between different areas of a large laboratory or working at a temporarily added experimental site, it can detect changes in the concentration of toxic and harmful gases in a timely manner. This makes up for the serious lag in the detection of potential risks by traditional fixed gas detectors at critical operating times, greatly improves the timeliness of monitoring, and ensures the safety of the experimenters and the smooth progress of the experiment.

[0017] 2. The laboratory air environment monitoring device, with GPS and WIFI positioning modules, continuously collects location data. The main control chip transmits this data to remote terminal devices via wireless communication modules. Managers can track the movement of laboratory personnel within the laboratory, and statistically analyze the usage frequency and personnel flow in different areas. This provides strong data support for optimizing laboratory space layout and safety management, and also enables them to locate staff members in a timely manner in case of emergencies.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6A laboratory air environment monitoring device includes a gas detection device 1 and an elastic band 2. The gas detection device 1 is detachably connected to the elastic band 2 via a connector 3. The laboratory air environment monitoring device of this utility model is mainly composed of a gas detection device 1, an elastic band 2 and a connector 3, which overcomes the drawbacks of fixed installation of traditional gas detectors and provides laboratory personnel with a convenient air environment monitoring experience.

[0027] The connector 3 includes a fixed shell 301, a back plate 302, and an elastic snap-fit ​​assembly; the fixed shell 301 is fixedly installed on one side of the elastic band 2, and a slot 303 is opened on one side of the fixed shell 301; the back plate 302 is fixedly installed on one side of the gas detection device 1, and an extended rod 304 is provided on the side of the back plate 302 away from the gas detection device 1, and a locking block 305 is provided at the end of the rod 304; the elastic snap-fit ​​assembly includes a telescopic rod 306, a spring 307, and a blocking block 308; the telescopic rod 306 is fixedly installed on the front and rear inner walls of the slot 303, and the blocking block 308 is fixedly connected to the end of each telescopic rod 306; the spring 307 is sleeved on the outer surface of each telescopic rod 306.

[0028] The locking block 305 and the blocking block 308 achieve unidirectional locking through a mutually compatible inclined structure.

[0029] Furthermore, the elastic band 2 is made of a spandex-nylon blend material, and its two ends are provided with mutually cooperating Velcro 201 to form a closed loop.

[0030] The primary function of the elastic band 2 is to ensure the portability of the device, allowing researchers to easily wear it on their arms for on-the-go air quality monitoring. Its two ends feature Velcro straps 201, one with a textured surface and the other with an adhesive surface, allowing for easy adjustment to suit different arm sizes and ensuring comfort and stability. Made of a blend of spandex and nylon, the elastic band 2 benefits from the elasticity of spandex, which provides excellent elasticity to accommodate varying arm circumferences and flexibly expand and contract during arm movement. Nylon enhances the material's abrasion resistance and strength, ensuring durability over long-term use. This blend also offers excellent breathability, effectively reducing discomfort such as stuffiness and sweating. Compared to traditional fixed gas detectors, researchers can move freely within the laboratory, accessing air quality information at their location whether conducting experiments in different areas or working at temporary experimental sites, significantly improving the flexibility and timeliness of monitoring.

[0031] Furthermore, the card block 305 is an isosceles trapezoid, and the two blocking blocks 308 are right-angled trapezoids, with the same inclination angle on their inclined surfaces.

[0032] Furthermore, a control rod 309 is fixedly installed on the top of each of the two blocking blocks 308.

[0033] Furthermore, the top of the fixed housing 301 has two openings that are adapted to the control lever 309 to enable manual unlocking.

[0034] When the rod 304 and the locking block 305 are inserted into the slot 303, the locking block 305 is an isosceles trapezoid, and the two blocking blocks 308 are right-angled trapezoids. The locking block 305 can smoothly push the blocking blocks 308 during the insertion process. When the locking block 305 is inserted into the slot 303, it pushes the blocking block 308 to compress the spring 307 and retract the telescopic rod 306. When the locking block 305 is fully inserted, the spring 307 rebounds, pushing the blocking block 308 to lock the locking block 305 and prevent it from coming out, thus achieving a stable connection between the gas detection device 1 and the elastic band 2. The top of each of the two blocking blocks 308 is fixedly equipped with a control rod 309. The top of the fixed housing 301 has two openings that are adapted to the control rods 309. When it is necessary to disassemble the gas detection device 1, the experimenter can pull the control rod 309 outward through the opening, which will cause the blocking block 308 to compress the spring 307 and retract the telescopic rod 306, thereby causing the locking block 305 to disengage from the locking block 308, making it easy to remove the gas detection device 1. The control lever 309 is fixedly connected to the blocking block 308, and the opening is adapted to the control lever 309 to form a convenient disassembly structure. It works in conjunction with other structures of the connector 3 to realize the quick connection and disassembly of the gas detection device 1 and the elastic band 2.

[0035] The gas detection device 1 is connected to the elastic band 2 via the connector 3, enabling the gas detection device 1 to move with the experimenter at any time. This separate fixing design allows the gas detection device 1 to be easily removed from the elastic band 2 for individual maintenance or installed in the usage position as needed when not in use, while it can be quickly and securely connected when worn.

[0036] Furthermore, the gas detection device 1 is internally equipped with a GPS module 101, a main control chip 102, a WIFI positioning module 103, and a wireless communication module 104. The GPS module 101, the WIFI positioning module 103, the wireless communication module 104, and the main control chip 102 are interconnected through a circuit system.

[0037] The GPS module 101 receives satellite signals to accurately obtain the geographical location information of the gas detection device 1, providing precise location data for experimenters in outdoor environments. The WIFI positioning module 103 searches for WIFI hotspot signals in the laboratory to achieve positioning in indoor environments. When experimenters are inside a large laboratory, the GPS signal may be weak due to factors such as building obstruction. In this case, the WIFI positioning module 103 can play a role in accurately determining the specific location of the experimenters. The main control chip 102 performs real-time analysis and processing of the location information from the GPS module 101 and the WIFI positioning module 103, automatically selecting the more precise positioning method according to different scenarios. On the one hand, it provides accurate positioning data; on the other hand, it is also responsible for receiving toxic and harmful gas concentration data from the gas sensor in the gas detection device 1. The wireless communication module 104 uses Bluetooth or 4G / 5G communication technologies to transmit the gas concentration data and location information processed by the main control chip 102 to the experimenter's mobile phone or other remote terminal device in real time. For example, if the gas detection device 1 detects that the concentration of toxic gas exceeds the safety threshold during the experiment, the main control chip 102 will quickly send the alarm information and current location to the laboratory management personnel and the experimenter's own mobile device through the wireless communication module 104 so that timely countermeasures can be taken to ensure the safety of the experimenter and the smooth progress of the experiment.

[0038] Working Principle: Before the experiment, the experimenter wraps the elastic band 2 around their arm and adjusts the tightness using the Velcro 201 at both ends to ensure a secure fit. The gas detection device 1 is quickly connected to the elastic band 2 via the connector 3. The specific steps include: aligning the rod 304 and locking block 305 on the back plate 302 with the slot 303 of the fixing shell 301 and inserting them. The inclined surface of the locking block 305 pushes the blocking block 308 to compress the spring 307. When the locking block 305 completely passes the blocking block 308, the spring 307 rebounds, pushing the blocking block 308 back to its original position, forming a mechanical lock to ensure a secure connection. During the experiment, the gas detection device 1 monitors the target gas (such as CO, H2S, NH3, etc.) in the laboratory air in real time and records the experimenter's location via the GPS module 101 and the WIFI positioning module 103. The monitoring data is processed by the main control chip 102 and transmitted to a remote terminal via the wireless communication module 104 for real-time viewing by management personnel. When the experiment is over and the device needs to be disassembled, pull the control rod 309 outward through the opening on the fixed shell 301. This will cause the blocking block 308 to compress the spring 307, releasing the limit on the locking block 305, and allowing the gas detection device to be easily removed for maintenance and storage.

[0039] In summary, this laboratory air environment monitoring device, with its elastic band 2 and Velcro 201 at both ends adjustable to fit the size of the experimenter's arm, can be easily worn on the arm. After the gas detection device 1 is connected to the elastic band 2 via connector 3, the experimenter can carry it at any time to continuously monitor the surrounding air environment. Whether moving between different areas of a large laboratory or working at a temporarily added experimental site, it can promptly detect changes in the concentration of toxic and harmful gases. This overcomes the shortcomings of traditional fixed gas detectors, which suffer from a serious lag in detecting potential risks during critical operations, greatly improving the timeliness of monitoring and ensuring the safety of experimenters and the smooth progress of experiments.

[0040] Furthermore, the GPS module 101 and the WIFI positioning module 103 continuously collect location data, and the main control chip 102 transmits this data to the remote terminal device through the wireless communication module 104. The management personnel can know the movement trajectory of the experimenters in the laboratory, count the usage frequency and personnel flow of different areas, provide strong data support for the optimization of laboratory space layout and safety management, and at the same time be able to find the staff member in time in case of emergency.
