Description

Technical Field

[0001] The utility model relates to the technical field of instruments and meters, in particular to a combustion performance detector for floor paving materials. Background Art

[0002] The flooring material combustion performance tester is an instrument specially used to test the combustion performance-related indicators of various flooring materials (wooden floors, carpets, and floor tiles). It mainly includes a combustion test chamber: this is the core space for conducting flooring material combustion tests, and an ignition system: responsible for providing a stable and adjustable fire source to ignite flooring material samples.

[0003] When using existing combustion performance testers for floor coverings, operators need to spend time walking to the instrument, manually opening the door to remove the sample, inserting a new sample, and then closing the door to restart the test program. This process is relatively cumbersome and increases the time of each test cycle.

[0004] A search of existing patents revealed a combustion performance tester for floor covering materials (publication number: CN211955358U). The tester comprises a frame, a combustion chamber, and a top cover. The bottom of the combustion chamber is fixedly connected to the frame, and the top of the combustion chamber is fixedly connected to the top cover. The frame includes three legs: one, two, three, and four. A calibration plate with several through-holes is located within the combustion chamber. A calorimeter is located within the combustion chamber, below the calibration plate. The calorimeter is fixedly connected to a moving block. A movable device for moving the moving block is provided on leg one, and a lifting device for raising and lowering the moving block is also provided on leg one. By providing the movable and lifting devices, the calorimeter can be automatically raised and lowered, allowing for better assessment of the stability of thermal radiation, improving safety, efficiency, and automation.

[0005] Although the above patent has achieved the goal of automatically raising and lowering and moving the heat flux meter by setting up a moving device and a lifting device, thereby better judging the stability of thermal radiation, making work safer, increasing work efficiency, and making the instrument more automated, if there is no ventilation component, the temperature in the test chamber will continue to rise, which will greatly affect the temperature sensor's accurate measurement of related indicators such as the heat release rate of material combustion.

[0006] Therefore, it is necessary to invent a combustion performance detector for paving materials to solve the above problems. Utility Model Content

The fan blades can rotate inside the frame through the rack and slider. During the rotation of the fan blades, the heat inside the box can be discharged. During the combustion test, the combustion of floor covering materials will release a large amount of heat, smoke and produce various changes in gas composition. The ventilation system can timely adjust the temperature, humidity, airflow and other environmental parameters in the test chamber to keep them within a relatively stable range, ensuring more accurate detection.
