Description

Technical Field

[0001] The utility model relates to the technical field of gas detection equipment, in particular to a combined VOC detection device. Background Art

[0002] The working principle of a handheld VOC detector is similar to that of a traditional VOC detector, but it is portable and has the characteristics of simplified operation. A handheld VOC detector usually uses technologies such as semiconductor sensors, PID sensors or electrochemical sensors to detect the concentration of volatile organic compounds (VOCs). The user brings the handheld VOC detector close to the area to be tested, allowing the VOCs in the air to enter the sampling port of the detector. The sampled air passes through the sensor, which generates a corresponding electrical signal based on the VOC concentration. The processing chip inside the handheld VOC detector converts the electrical signal into a VOC concentration value and displays the result to the user through a display screen or indicator light.

[0003] Most of the existing VOC detectors are of an integrated structure, which means that when the equipment is damaged, it needs to be returned to the factory for repair. The operation is very cumbersome and the maintenance cost is high. In particular, the battery of the equipment is an integrated structure. When the equipment runs out of power after continuous work, it needs to be stopped and charged. It can only be used again after the equipment is fully charged. The battery life of the equipment is short, which affects the detection efficiency. Therefore, a combined VOC detection device is needed to solve the above problems. Utility Model Content

When a single module is damaged, only the damaged module needs to be replaced, which reduces the maintenance difficulty and maintenance cost of the equipment. The power module can be disassembled and charged separately. When the equipment is out of power, the power module can be replaced and used again, which improves the battery life of the equipment. The magnetic sliding connection installation method greatly improves the equipment assembly efficiency.

[0015] 2. The utility model sets a protective cover on the outside of the detector body, which covers the side wall of the detector body, thereby preventing the surface module from falling off or being damaged due to bumps during the use of the detector. At the same time, it blocks the upper end surface of the display module and the control module to prevent the display module and the control module from loosening or falling off during use, thereby further improving the stability of the equipment.
