[0002] In industrial production, warehousing management, environmental monitoring and other scenarios, monitoring a single parameter is no longer sufficient to meet the needs of comprehensive control over complex environments. The detection device that integrates temperature, humidity and VOC concentration is an environmental sensing terminal that integrates multiple sensing units. It integrates temperature and humidity sensors (collecting ambient temperature and humidity parameters) and VOC sensors (detecting the concentration of volatile organic compounds such as formaldehyde and benzene) in a small protective housing, and with signal processing and communication modules, it can realize the synchronous acquisition, processing and output of multi-dimensional environmental data.

[0003] Currently, in some warehousing and other environments, detection devices that integrate temperature and VOC concentration detection are used. These devices typically consist of two housings, a chip, and an interface. However, the common method for installing the detection chip is to fix the two housings together with screws. When performing disassembly and maintenance, tools are required to complete the disassembly and maintenance work, which affects the efficiency of maintenance and installation. Utility Model Content

[0015] 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.

[0016] Please see Figures 1-4 As shown, a device for detecting temperature, humidity, and VOC concentration includes a base shell 1, and further includes: The cover plate 2 is located inside the bottom shell 1. The circuit board body 3 is located inside the bottom shell 1. Positioning shells 4 are fixedly connected to both sides of the bottom shell 1. The mounting component 5 is located inside the positioning shell 4. The mounting component 5 includes a first toothed plate 501, which is located inside the positioning shell 4. A heat dissipation groove 6 is provided on one side of the bottom shell 1, and a connecting groove 7 is provided inside the cover plate 2. The bottom shell 1 and the cover plate 2 are used to facilitate the installation and positioning of the circuit board body 3. The positioning shell 4 and the mounting part 5 are used to facilitate the quick positioning and installation of the cover plate 2 and facilitate subsequent maintenance. It should be noted that the circuit board body 3 integrates a temperature and humidity sensor and a VOC sensor to detect the concentration of volatile organic compounds. It also includes signal processing and communication circuits. This is existing technology and can be clearly understood by those skilled in the art. It will not be described in detail here.

[0017] Mounting component 5 also includes a spring assembly 502 fixed to one side of the interior of the positioning housing 4. A second toothed plate 503 is fixedly connected to one side of the spring assembly 502, and a push rod 504 is fixedly connected to one side of the second toothed plate 503. The surface of the push rod 504 is slidably connected to the interior of the positioning housing 4. Mounting component 5 also includes a sliding groove 505 formed inside the positioning housing 4. Sliding blocks 506 that are slidably connected to the inside of the sliding groove 505 are fixedly connected to both sides of the second toothed plate 503. A positioning ring 507 is sleeved on the surface of the push rod 504, and one side of the positioning ring 507 is connected to the positioning housing. 4. Fixing: A mounting plate 508 is fixedly connected to the top of the first toothed plate 501. One side of the mounting plate 508 is fixed to the cover plate 2. When the user needs to disassemble the first toothed plate 501, he / she presses the push rod 504. As the push rod 504 moves, it will drive the second toothed plate 503 to compress the spring assembly 502. As the second toothed plate 503 moves, it will drive the slider 506 to slide within the slide groove 505. At this time, the second toothed plate 503 will detach from the surface of the first toothed plate 501, thereby completing the disassembly work. Then the cover plate 2 can be removed.

[0018] Interfaces 8 are fixed on both sides of the top of the circuit board body 3. A positioning hole 9 is opened on one side of the bottom shell 1. A fixing hole 10 is opened inside the cover plate 2. A positioning pin 11 is inserted into the fixing hole 10. The interface 8 on the top of the circuit board body 3 is used for power supply and data transmission. The fixing hole 10 on the cover plate 2, together with the positioning pin 11, facilitates the auxiliary limiting of the cover plate 2 at the top of the cover plate 2.

[0019] Working principle: The device forms a protective cavity through the bottom shell 1 and the cover plate 2. The internal circuit board 3 integrates temperature and humidity sensors, VOC sensors, signal processing, and communication circuits to achieve synchronous acquisition and data output of multiple environmental parameters. During assembly, the cover plate 2 drives the first toothed plate 501 to insert into the positioning shell 4 through the side mounting plate 508. The spring assembly 502 pushes the second toothed plate 503 to engage with the first toothed plate 501. With the help of the positioning pin 11, the fixing hole 10 and the positioning hole 9 are inserted to complete the quick positioning and fixing of the cover plate 2. During disassembly and maintenance, pressing the push rod 504 drives the second toothed plate 503 to compress the spring assembly 502 and disengage from the first toothed plate 501, so that the cover plate 2 can be removed. The heat dissipation groove 6 of the bottom shell 1 ensures stable heat dissipation of the circuit board 3. The interface 8 is used for power supply and data transmission, and the whole device realizes convenient assembly, maintenance and stable testing functions.
