The atomizer 33 is arranged inside the atomizing chamber 32, and is fixed by the clamping connection between the connecting pin 331 and the recess 321, so that the atomizer 33 is prevented from moving freely in the atomizing chamber 32, the atomizer 33 is prevented from colliding with the atomizing chamber 32 in the using process, and the service life of the atomizing unit 3 is prolonged.

Furthermore, a sponge and a drying agent for absorbing the condensate are arranged in the condensation chamber 5. The function of both the sponge and the desiccant is to absorb the condensation water dripping from the containing chamber 11.

Further, the distance between the bottom end of the suction nozzle 2 and the bottom end of the accommodating cavity 11 is greater than or equal to the distance of the rotary switch 72 rotating and pressing the protrusion 23 to move downwards when the push plate 71 is pressed.

The bottom end of the suction nozzle 2 is at a distance from the bottom end of the accommodating cavity 11, the distance is required to be equal to or larger than the distance for downwards extruding the push plate 71 when the suction nozzle 2 is ejected, the rotary switch 72 is rotated to force the protrusion 23 to downwards move until the distance between the rotary switch 72 and the protrusion 23 is separated, if the distance between the suction nozzle 2 and the accommodating cavity 11 is too small, the suction nozzle 2 will impact the bottom of the accommodating cavity 11 when the rotary switch 72 extrudes the protrusion 23, and the service life of the medical evaporative type suction device is shortened. In addition, the length of the nozzle 2 ejected from the housing 1 needs to be consistent with the distance between the bottom of the bump 23 and the rotary switch 72, when the ejection distance of the nozzle 2 is too large, the nozzle 2 returns to the lap joint state of the rotary switch 72 and the bump 23 without being completely retracted into the accommodating cavity 11, the nozzle 2 is placed outside the accommodating cavity 11, the design is not attractive, and the nozzle 2 is easily polluted; when the ejection distance of the suction nozzle 2 is too small, the suction nozzle 2 needs to be pressed deep inside the housing chamber 11, and the user experience is not good.
