It uses the latest high-end microprocessor technology and has many practical functions such as preheating and heat preservation, power setting, real-time temperature, and drainage control. It also has multiple safety protection designs. In combination with drugs, it is suitable for local fumigation treatment of human joints and soft tissue diseases. Its main body is a heating component that heats the Chinese medicine liquid and then generates liquid medicine steam. The liquid medicine steam is output through the nozzle and acts on the lesion position on the human body surface. During the continuous use of steam output, the steam temperature will fluctuate with the ambient temperature or the different usage methods. When the temperature exceeds the heat resistance temperature of the human skin, it will cause discomfort or the risk of scalding. Therefore, there will be a contact sensor in the design to detect the human skin temperature in real time so as to give timely prompts. However, the sensor will be affected by the steam output during the temperature measurement process. During the output of liquid medicine steam, there is no steam isolation protection device, which will affect the measurement accuracy of the sensor. Long-term use can easily cause damage to the sensor, affecting the service life of the built-in sensor. Therefore, it is necessary to design a nozzle protective cover for the fumigation therapy device. Utility Model Content
