The invention provides a breathing machine, and belongs to the field of breathing machines. The breathing machine in the invention comprises a heat source assembly, a heat conduction device, an exhalation valve assembly, a first heater, a second heater, a temperature sensor and a controller; the heat source assembly is connected with the first heater through the heat conduction device; the first heater, the second heater and the temperature sensor are tightly attached to the exhalation valve assembly respectively; and the controller is connected with the temperature sensor and the second heater respectively. The breathing machine in the invention has the beneficial effects that: heat generated in the operation process of heat source assemblies, such as a power module and a turbofan, is conducted to the exhalation valve assembly; basic heat energy is provided for the exhalation valve assembly; the second heater of an exhalation valve can keep the exhalation valve assembly above the needed temperature only with relatively small heating power, so that exhalation condensate water is prevented from being generated; electric energy of the breathing machine is saved; the service life of the breathing machine is prolonged; and the breathing machine is more energy-saving and environment-friendly.
Description
technical field [0001] The invention relates to the field of ventilators, in particular to a ventilator. Background technique [0002] The exhalation valve assembly of the ventilator generally has sensors such as exhalation flow, pressure, and carbon dioxide, which are used to monitor the patient's respiratory physiological state. Such sensors are required to avoid contact with liquid water to prevent the accuracy of data collection from being affected or even the sensor being damaged. . During the working process of the ventilator, the warm and humid gas exhaled by the patient is likely to form condensation water when it is cooled by the exhalation valve assembly of the ventilator, and come into contact with the above sensors, especially for infants, the phenomenon of condensation water in the exhalation valve is more serious. [0003] Among the existing technical means, a common method to prevent condensed water from contacting the exhalation valve sensor is to directly u...
