Sensors such as expiratory flow, pressure and carbon dioxide are commonly arranged in an expiratory valve component of the respirator and used for monitoring the respiratory physiological state of a patient, and the sensors are required to be prevented from contacting liquid water and the accuracy of acquired data is prevented from being influenced or even damaged. During the operation of the respirator, the warm and humid air exhaled by the patient is easy to form condensed water when the respirator exhalation valve assembly is cooled, and the condensed water is in contact with the sensor, especially for infants, the phenomenon of the condensed water of the exhalation valve is more serious.
Among the prior art approaches, a common method for preventing condensed water from contacting the exhalation valve sensor is to use a heater directly to heat the exhalation valve assembly as a whole, so that warm and humid gas exhaled by the patient is no longer condensed when cooled. Generally, the electric power consumption of the heater is usually high, and in order to avoid too high electric power consumption, the respirator cannot supply power to the heater for a long time or even cannot supply power in a battery-powered state.
The existing breathing machine usually comprises a power module, a turbo fan and other high-power components, which inevitably generate high heat in the operation process and need a fan, a radiator and the like to actively dissipate heat, otherwise, the working performance is negatively affected.

As shown in fig. 1, the heat source assembly 1 includes a power module, a turbo fan and other heating assemblies arranged in the respirator, and the power module, the turbo fan and other elements have higher power in the operation process, so that the generated heat is higher.
As shown in fig. 2, the first heater 5 is disposed around the exhalation valve assembly 9, the end of the heat conducting pipe 4 connected to the first heater 5 extends into the first heater 5 and is disposed along the length direction of the first heater 5, and the length of the end of the heat conducting pipe 4 extending into the first heater 5 is shorter than the length of the first heater 5. One end of the heat conducting pipe 4 extends into the first heater 5, so that heat emitted by the heat source assembly 1 can be well conducted to the first heater 5, and the first heater 5 is arranged to surround the exhalation valve assembly 9, so that basic heating can be better provided for the exhalation valve assembly 9.
As shown in fig. 2, the heat conductor includes a heat collector 3 and a third heat conduction layer 2 with one side attached to the heat collector, the other side of the third heat conduction layer 2 is closely attached to the heat source assembly 1, the heat collector 3 is connected to the heat conduction pipe 4, and the heat conduction layer can conduct heat better.
As shown in fig. 2, the first heater 5 is provided with a first heat conducting layer 7, and the first heat conducting layer 7 is closely attached to the exhalation valve assembly 9, so that the heat conducting layer can conduct heat better.
