Abstract
Description
Technical Field
[0001] This utility model provides a portable intelligent fumigation gas detection device, belonging to the technical field of fumigation detection equipment. Background Technology
[0002] Fumigation is a widely used disinfection and pest control method in modern agriculture, warehousing and logistics, import and export trade, and public health. However, the gases produced during fumigation are highly toxic and potentially dangerous; improper handling can lead to serious consequences such as poisoning, environmental pollution, and even explosions. Therefore, fumigation gas detection devices are needed; these devices are used to detect and monitor the concentration of gases during fumigation. Their main function is to measure the concentration of specific gases in the environment in real time using sensor technology and provide data feedback to operators.
[0003] Traditional gas detection equipment is usually large in size, complex to operate, troublesome to disassemble, lacks aesthetic appeal, and is not easy to carry, especially in scenarios that require frequent movement; at the same time, existing fumigation detection devices have limited functionality and poor expandability. Utility Model Content
[0004] The technical problem this invention aims to solve is that traditional fumigation testing devices have limited functionality, poor expandability, are inconvenient to carry, and are complex to operate.
[0005] To address the aforementioned problems, the proposed technical solution is as follows: a portable intelligent fumigation gas detection device, comprising a detection box with a lifting plate rotatably connected to it; a Python programmable module is installed inside the detection box; a sampling port communicating with the interior of the detection box is opened on the side of the detection box, and a temperature interface is provided on one side of the detection box; the side wall and upper surface of the detection box are an integrated structure, and a disassembly assembly is provided on the bottom surface of the detection box; a power connection port capable of providing power to the detection box is provided on the side of the detection box.
[0006] As an improvement, the side of the detection box is provided with a return air port corresponding to the sampling port.
[0007] As an improvement, the disassembly assembly includes a sealing plate and fastening screws; the bottom of the test box has a slot, the sealing plate located in the slot blocks the bottom of the test box, and the sealing plate is fixedly connected to the test box by fastening screws.
[0008] As an improvement, a switch button is provided on the side of the testing box to control the operation of the entire testing box.
[0009] As an improvement, the power connection port is a standard Type-C interface that can connect to a power bank.
[0010] The beneficial effects of this utility model are:
[0011] 1. The structure is compact and flexible, easy to maintain. The detection device can be disassembled from the bottom, with no screws on the sides, making it aesthetically pleasing. All internal components are connectors.
[0012] 2. Flexible system architecture and strong scalability. Unlike traditional microcontroller designs, this device adopts the latest Python programmable module design, which facilitates the integration of modules such as temperature and humidity sensors, concentration sensors, pressure sensors, cameras, AI voice modules, and IoT modules. The development cycle is short, the functions are powerful, and modules can be added or removed at any time to meet new customer requirements.
[0013] 3. Charging uses a standard Type-C interface, supporting mobile phone power banks and avoiding the constraints of dedicated chargers; this greatly increases the working time. The original charging time of about 8 hours can be extended to a sufficiently long time when combined with a power bank. It can also be charged in a car, offering convenience and flexibility.
