Description

Technical Field

[0001] This utility model relates to the field of calibration box technology, and in particular to a cigarette box annular calibration box. Background Technology

[0002] Fires are often accompanied by three combustion products: smoke, heat, and light. In the early stages of a fire, due to the low temperature, most materials are in a smoldering stage, resulting in a large amount of smoke. Smoke is one of the important characteristics of an early fire. Smoke detectors are developed based on this characteristic and can detect visible or invisible smoke particles. A smoke detector is a device that converts changes in the smoke concentration at the detection location into an electrical signal to achieve the purpose of alarm. Therefore, the calibration of smoke detectors and smoke alarms is particularly important. Smoke detector calibration boxes are often used for the calibration of smoke detectors.

[0003] Existing calibration chambers typically have low detection efficiency, complex testing procedures, and uneven smoke distribution within the chamber, which negatively impacts the smoke detection process. To address these shortcomings, we propose a ring-shaped smoke chamber calibration chamber. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A ring-shaped calibration box for cigarette boxes includes an upper cigarette box and a lower cigarette box below the upper cigarette box. A set of semi-circular smoke guide boxes is provided between the left and right ends of the upper and lower cigarette boxes. Two sets of mounting plates are installed on the rear outer wall of the upper cigarette box. A set of sliding components is provided at the rear end of each of the two sets of mounting plates. Each sliding component includes a movable base plate. A set of slide rails is slidably connected to both sides of the movable base plate. A tray is provided at the upper end of the movable base plate. Six sets of smoke detectors to be tested are provided at the upper end of each tray. Two sets of movable support plates are provided at the front end of each movable base plate. An inlet / outlet is provided in the middle of each of the two sets of mounting plates. An opening is provided behind each of the two sets of inlets / outlets on the rear outer wall of the upper cigarette box. The two sets of movable support plates at the front end of each of the two sets of movable base plates extend into the interior of the upper cigarette box through the middle of the inlet / outlet.

[0007] Preferably, a connecting frame is provided between the two sets of smoke guide boxes and the openings at both ends of the upper smoke box and the lower smoke box, respectively, and the two sets of smoke guide boxes are detachably connected to the upper smoke box and the lower smoke box through the connecting frame.

[0008] Preferably, each of the two sets of smoke guide boxes is provided with an exhaust fan on its front side, and a guide fan is also provided on the outer wall of one of the smoke guide boxes above the exhaust fan.

[0021] like Figures 1-4 As shown, a ring-shaped smoke box calibration box includes an upper smoke box 1 and a lower smoke box 2 below the upper smoke box 1. A set of semi-circular smoke guide boxes 3 are provided between the left and right ends of the upper smoke box 1 and the lower smoke box 2. The two sets of smoke guide boxes 3, together with the upper smoke box 1 and the lower smoke box 2, form a ring structure, allowing smoke to flow inside. A connecting frame 14 is provided between the two sets of smoke guide boxes 3 and the openings at both ends of the upper smoke box 1 and the lower smoke box 2, respectively. The connecting frame 14 is used to connect the smoke guide boxes 3 to the upper smoke box 1 and the lower smoke box 2. An exhaust fan 8 is provided on the front side of each set of smoke guide boxes 3, used to exhaust the smoke inside the calibration box outwards. Above the exhaust fan 8, a guide fan 9 is also provided on the outer wall of one side of the smoke guide box 3, used to guide the airflow exhausted by the exhaust fan 8 upwards, preventing it from spreading around the working environment. Below, a smoke generating chamber 11 is also provided, and a smoke generator 12 is installed inside the smoke generating chamber 11. The smoke generator 12 is a component used to generate smoke. The smoke generating chamber 11 is used to install the smoke generator 12. A guide fan 13 is also provided inside the lower part of the smoke guide box 3 on one side. The guide fan 13 allows the smoke to flow inside the annular calibration box and provides gas flow rate. A smoke sensor 10 is also provided on the outer wall of the smoke guide box 3 on one side. The front end of the smoke sensor 10 extends into the interior of the smoke guide box 3. The smoke sensor 10 is used to sense the smoke concentration inside the annular calibration box. Multiple sets of transverse baffles 15 are provided inside the lower smoke box 2. The baffles 15 are used to make the smoke flow and distribution inside the annular calibration box more uniform. A base 4 is provided at the lower end of the lower smoke box 2. The base 4 is used to support the annular calibration box.

[0022] like Figures 1-4As shown, two sets of mounting plates 22 are installed on the rear outer wall of the upper smoke box 1. A set of sliding components 5 are respectively provided at the rear end of each of the two sets of mounting plates 22. The mounting plates 22 are used to install the sliding components 5. The sliding components 5 include a movable base plate 17. A set of slide rails 18 are slidably connected to both sides of the movable base plate 17, allowing the movable base plate 17 to move via the slide rails 18. A tray 19 is provided at the upper end of the movable base plate 17. Six sets of smoke detectors 20 to be tested are provided at the upper end of each tray 19. The tray 19 is used to install and fix the smoke detectors 20 to be tested. The smoke detectors 20 can perform detection once they enter the interior of the upper smoke box 1. Two sets of movable support plates 21 are provided at the front end of each movable base plate 17. A set of sliding support plates 21 is provided between the two sets of mounting plates 22. The upper smoke box 1 has an opening on the rear outer wall of each of the two sets of inlets and outlets 16. The two sets of movable trays 21 at the front end of the two sets of movable base plates 17 pass through the middle of the inlets and outlets 16 and extend into the interior of the upper smoke box 1. The tray 19 can be moved into the interior of the upper smoke box 1 by the movable trays 21, and the six sets of smoke detectors 20 to be tested on the upper end of the tray 19 are transported into the interior of the upper smoke box 1. A set of display screens 6 are installed on the upper outer wall of each of the two sets of mounting plates 22. The display screens 6 are electrically connected to the smoke sensors 10. The smoke sensors 10 are also electrically connected to a computer. The display screens 6 can display the detection information. A set of support rods 7 are respectively provided below the two sets of sliding components 5. The support rods 7 are used to support the sliding components 5.

[0023] It should be noted that this utility model is a ring-shaped calibration box for smoke chambers. In use, the smoke detectors 20 to be tested are placed on the upper ends of two sets of trays 19 respectively. The upper end of one set of trays 19 can hold six sets of smoke detectors 20 to be tested. Then, the smoke detectors 20 to be tested are moved into the interior of the upper smoke chamber 1 by moving the base plate 17 and the slide rail 18. The smoke generator 12 inside the smoke generating chamber 11 is activated, generating smoke inside the smoke guide box 3 on one side. Then, the guide fan 13 is activated, blowing the smoke between the upper smoke chamber 1 and the lower smoke chamber. The smoke flows through the two sets of smoke guide boxes 3. When the smoke passes through the baffle bar 15, it is disturbed, making the smoke flow and distribution inside the annular calibration box more uniform. When the smoke passes through the surface of the smoke detector 20 under test inside the upper smoke box 1, the smoke detector 20 under test can be detected. The detection results will be displayed at the top of the two sets of display screens 6. After the detection is completed, the exhaust fan 8 on the outer wall of the two sets of smoke guide boxes 3 is started. The smoke inside the annular calibration box will be discharged outward through the exhaust fan 8 and guided upward through the guide fan 9.
