[0002] A humidifier is a commonly used device in medical equipment, which is used to humidify the air-oxygen mixture supplied to patients. Under normal circumstances, the respiratory tract provides the humidification and heating functions required during breathing by moistening and warming the nasal and upper respiratory tract mucosa. However, in some cases, such as humidifier-assisted ventilation, artificial airway intubation, and patients losing their ability to breathe independently, the loss of this natural humidification and heating function can lead to problems such as dryness and damage to the respiratory mucosa.

[0003] When the gas temperature provided by the humidifier is low, it may cause irritation and discomfort to the patient's respiratory tract, and may lead to respiratory spasm or irritation reaction. Especially for patients who rely on humidifiers for a long time, hypothermia may have a negative impact on their health and recovery. In order to improve the patient's comfort and treatment effect, it is often necessary to meet the patient's needs by heating the respiratory airflow, and heating can also increase the humidity of the gas to a certain extent. However, in the process of heating the airflow, accurate control and stability of the temperature are very important.

[0004] At present, it is common to set a temperature controller in the gas pipeline to monitor and adjust the temperature of the heating wire. However, in the prior art, the fixing problem of the temperature controller has always been a challenge. During operation, the temperature controller may be displaced or loose, resulting in unstable or even uncontrolled temperature of the heating wire, thus affecting the normal operation of the humidifier heating tube.
