Detailed Embodiment
[0019] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe the specific embodiments of the present utility model in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a thorough understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0020] Referring to Figures 1-3 , a dry - burning - proof fire alarm, comprising a base 1. On one side of the base 1, there is a sealing frame 2. On one side of the sealing frame 2, there are a flame detection port 3, an ultraviolet detection port 4, and a temperature detection port 5. On the side wall of the sealing frame 2, there is an infrared probe 6. On one side of the base 1, there is a protection mechanism for protecting the sealing frame 2. The protection mechanism includes a protection frame 7 fixedly connected to one side of the base 1. The protection frame 7 is located inside the sealing frame 2 and sleeved on one side of the sealing frame 2.
[0021] On one side of the base 1, there is a power supply slot 8. A power supply is provided in the power supply slot 8. The power supply is connected to a flame detector, an ultraviolet detector, a temperature detector, and the infrared probe 6 through wires. The connecting wire 11 passes through the sliding frame 10 to connect to the power supply.
[0022] On one side of the base 1, there is a sliding frame 10. On one side of the sliding frame 10, there is a fixedly connected connecting wire 11. On one side of the connecting wire 11, there is an installation ring 12. Inside the installation ring 12, there is a fixedly connected flow sensor 13. On one side of the installation ring 12, there is a valve switch 17. On the side wall of the installation ring 12, there is a control mechanism for controlling the opening and closing of the valve switch 17. The control mechanism includes an electric telescopic rod 14 fixedly connected to one side of the installation ring 12. The telescopic end of the electric telescopic rod 14 is provided with a connecting frame 15. The connecting frame 15 is rotatably connected to the valve switch 17. Activity slots 16 are provided on the telescopic end of the electric telescopic rod 14 and the side wall of the connecting frame 15. A plurality of activity slots 16 on both sides are installed through pin shafts.
[0023] When the utility model is in use, first place the base 1 at the gas stove. At this time, the protective frame 7 isolates the heat from the bottom of the gas stove to the sealing frame 2, avoiding damage to the sealing frame 2 and various sensors inside it. At this time, the flame detector in the flame detection port 3 detects the flame during the use of the gas stove, the ultraviolet sensor in the ultraviolet detection port 4 conducts ultraviolet detection, and the temperature sensor in the temperature detection port 5 detects and monitors the temperature during the use of the gas stove in cooperation with the infrared probe 6 to determine whether someone is watching when the values of temperature, flame, ultraviolet, etc. reach the threshold. When the infrared probe 6 does not sense that someone is watching, at this time, the signal is transmitted through the connecting wire 11 to control the electric telescopic rod 14 to drive the connecting frame 15. Under the connection of the movable slot 16 and the rotational connection with the valve switch 17, the continuous supply of gas to the gas pipeline can be cut off, thereby effectively avoiding the continuous problem of the dry-burning state. Among them, the flow sensor 13 extends into the gas pipeline to monitor the flow rate through the gas pipeline. When the flow rate value is lower than the normal flow rate value, an alarm is issued. At this time, it is necessary to detect and handle the leakage problem of the pipeline.
