The invention belongs to the technical field of medical devices, and particularly discloses a medical care atomizer which comprises a liquid storage chamber, an atomizing chamber and a mist outlet pipe. The mist outlet pipe is communicated with the atomizing chamber, a gas conveying pipe is disposed in the liquid storage chamber, the upper end of the gas conveying pipe is communicated with the atomizing chamber, a pressure limiting valve is arranged in the gas conveying pipe, one end of the gas conveying pipe communicated with the atomizing chamber is in a horn shape expanded outwards, an atomizing net is sealed on a horn aperture, a flow limiting pipe with the pore diameter smaller than that of the gas conveying pipe is disposed between the gas conveying pipe and a horn-shaped port, the flow limiting pipe is in an arc shape expanded gradually, a plurality of flow guide plates are staggered on the left-right inner wall of a pipe between the flow limiting pipe and the horn-shaped opening, the cross section of each flow guide plate is smaller than that of the pipe, the lower end of the gas conveying pipe is connected with an air compression device, capillarity tubes communicated witheach other are disposed around the inside of the liquid storage chamber, and the capillarity tubes are communicated with the gas conveying pipe. The liquid storage chamber, the capillarity tubes andthe gas conveying pipe are elastic. According to the scheme, the atomizing effect is good, and it is easy to clean residual liquid medicines in the atomizer.
