DETAILED DESCRIPTION

[0012] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the examples described here are only for illustrating and solidifying the utility model, and are not for limiting the utility model.

[0013] As shown in Figure 1 A simple temperature alarm device suitable for acid-base environment, comprising: temperature trigger 1, conductor 2, acoustic and light alarm component 3, power switch 4, low-boiling-point fire-retardant medium 13. Temperature trigger 1 is composed of trigger casing 5, adjusting spring 6, trigger baffle 7, baffle limiting component switch 8 and baffle limiting component 9, and acoustic and light alarm component 3 is composed of acoustic and light alarm 10, alarm power supply base casing 11 and safety battery 12.

[0014] The low-boiling-point fire-retardant medium 13 is filled in the trigger housing 5, and the trigger baffle 7 is arranged inside the trigger housing 5. One side of the trigger baffle 7 is the low-boiling-point fire-retardant medium 13, and the other side is connected with the adjusting spring 6. The adjusting spring 6 is connected with the trigger housing 5 away from one side of the trigger baffle 7. Four baffle limiting assemblies 9 are arranged on the upper and lower sides of the trigger baffle 7, which are an upper right baffle limiting 9-1, a lower right baffle limiting 9-2, an upper left baffle limiting 9-3 and a lower left baffle limiting 9-4. The baffle limiting assembly switches 8 are arranged at the same height as the upper right baffle limiting 9-1 and the upper left baffle limiting 9-3. The baffle limiting assembly switches 8 are connected with wires which are led out from the inside of the trigger housing 5. The negative pole of the external wire 2 of the baffle limiting assembly switch 8 is connected with the negative pole of the safety battery 12 through the power switch 4, and the positive pole of the external wire 2 of the baffle limiting assembly switch 8 is directly connected with the positive pole of the safety battery 12. The safety battery 12 is arranged in the alarm power supply base housing 11, and the sound-light alarm 10 is fixed on the alarm power supply base housing 11 by means of adhesion.

[0015] When the external temperature rises, the low-boiling-point fire-retardant medium in the trigger housing 5 is heated and expanded, the saturated vapor pressure is increased, the trigger baffle 7 is pushed, and the adjusting spring 6 is compressed. When the limited temperature is reached, the trigger baffle 7 is connected with the baffle limiting assembly switch 8. When the power switch 4 is closed, a circuit loop is formed, the sound-light alarm 10 is powered and alarms. The staff hears the alarm and takes corresponding emergency measures. After the temperature anomaly is eliminated, the temperature decreases, the saturated vapor pressure decreases, the low-boiling-point fire-retardant medium returns to the original state, the adjusting spring 6 deforms and pushes the trigger baffle 7 to reset, the circuit is powered off, and the sound-light alarm 10 stops alarming.

[0016] The above only describes the preferred embodiments of the present application, and it should be pointed out that, for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and deformations can be made, and these improvements and deformations should be considered as the protection scope of the present application.
