[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0023] Referring to Figures 1-4 , an embodiment provided by the present utility model: a fully sealed high-temperature-resistant wireless temperature measurement transmitting device, including a protective bottom shell 1, a protective top cover 2 is threadedly connected to the left end of the protective bottom shell 1, a battery 6 for power supply is fixedly connected to the inner wall of the protective bottom shell 1, a reinforcing rib 3 for dividing the space of the protective bottom shell 1 is fixedly connected to the top of the battery 6, a smart control board 4 is fixedly connected to the top of the reinforcing rib 3, an antenna 5 is fixedly connected to the left end of the smart control board 4, and the upper and lower ends of the antenna 5 are fixedly connected to the inner wall of the protective bottom shell 1 for transmitting temperature signals. A first connector 7 is threadedly connected to the bottom end of the protective bottom shell 1, an armored wire 8 is fixedly connected to the bottom end of the first connector 7, the other end of the armored wire 8 is fixedly connected to a second connector 9, and the top end of a metal shell 10 is fixedly connected to the bottom end of the second connector 9 for transmitting temperature signals. A sensor chip 12 is fixedly connected to the inner wall of the metal shell 10, a thermal conductive silicone grease 13 is provided on the inner wall of the protective bottom shell 1 relative to the bottom end of the sensor chip 12, and a magnesium oxide powder 11 is provided on the inner wall of the protective bottom shell 1 relative to the top end of the sensor chip 12 for measuring the external temperature. A cable 14 is fixedly connected to the inner wall of the armored wire 8, and the bottom end of the reinforcing rib 3 is connected to the top end of the sensor chip 12 through the cable 14. The cable 14 and the first connector 7 are filled with resin glue, and the second connector 9 and the metal shell 10 are connected through welding treatment;

[0024] Specifically, the sensor chip 12 located on the inner wall of the metal shell 10 serves as the core temperature measurement element, and its sensitive element senses the temperature of the external environment. Since the sensor chip 12 is installed inside the metal shell 10, the thermal conductive silicone grease 13 and the magnesium oxide powder 11 are filled between the protective bottom shell 1 and the sensor chip 12. As a thermal interface material, the thermal conductive silicone grease 13 can effectively improve the efficiency of heat transfer from the metal shell 10 to the sensor chip 12. When the sensor chip 12 detects the temperature, the temperature signal will be transmitted to the smart control board 4 through the cable 14. The cable 14 and the first connector 7 are filled with resin glue. This filling method not only enhances the fixing of the cable 14 but also improves the sealing and waterproof performance of the entire device, ensuring stable operation in harsh environments such as high temperature and humidity. The smart control board 4 processes the temperature signal from the sensor chip 12 and transmits it wirelessly through the antenna 5.

[0025] Working principle: First, the sensor chip 12 located on the inner wall of the metal housing 10 serves as the core temperature measuring element, and its sensitive element senses the temperature of the external environment. Since the sensor chip 12 is installed inside the metal housing 10, thermal conductive grease 13 and magnesium oxide powder 11 are filled between the protective bottom shell 1 and the sensor chip 12. As a thermal interface material, the thermal conductive grease 13 can effectively improve the efficiency of heat transfer from the metal housing 10 to the sensor chip 12. When the sensor chip 12 detects the temperature, the temperature signal will be transmitted to the intelligent control board 4 through the cable 14. The cable 14 and the first connector 7 are filled with resin glue. This filling method not only enhances the fixation of the cable 14, but also improves the sealing and waterproof performance of the whole device, ensuring stable operation in harsh environments such as high temperature and humidity. The intelligent control board 4 processes the temperature signal from the sensor chip 12 and emits it wirelessly through the antenna 5. This wireless transmission method not only avoids problems such as complex wiring and easy damage in the traditional wired temperature measurement method, but also improves the flexibility and convenience of temperature measurement. In addition, this device also adopts a fully sealed design. Through the close cooperation of the protective bottom shell 1, the protective top cover 2, the first connector 7, the armored cable 8, the second connector 9 and the metal housing 10, the effects of dust prevention, waterproofing and electromagnetic shielding are achieved. At the same time, these components are all made of high-temperature resistant and corrosion-resistant materials, ensuring the long-term stable operation of the device in harsh environments. The armored cable 8 serves as the transmission channel for signals and power. Its internal multi-layer structure can effectively resist external mechanical shocks and electromagnetic interference, improving the reliability and security of data transmission.
