Embodiment 1

[0027] Such as Figure 1-2 As shown, a centrifugal accelerated evaporation device includes: a volatilization seat 1, a connecting seat 2, a liquid injection joint 3, a liquid injection ball 4, a hydraulic injection spring 5, a motor 6, a first sealing ring 7, The second sealing ring 8, the third sealing ring 9, the rotating bearing 10, the fan 11, the valve core 12, the fourth sealing ring 13, the slide valve compression spring 14 and the plug 15;

[0028] Both ends of the volatilization seat 1 are provided with an air inlet and an air outlet, which are respectively connected to the air inlet and outlet pipes of the main breathing circuit. A circular cavity is opened in the middle of the volatilization seat, and a small hole is opened at the bottom of the cavity to communicate with the outside world.

[0029] The center of the fan 11 is a hollow shaft, and small holes are evenly distributed in the connection gap between the fan blade and the shaft. A groove is arranged at th...

Abstract

The invention belongs to the technical field of liquid evaporation, and particularly relates to a centrifugal accelerated evaporation device which comprises a volatilization seat, a connecting seat, a motor, a fan, a liquid injection assembly and a one-way slide valve. An open cavity is formed in the volatilization seat, and an air inlet and an air outlet are formed in the two sides of the cavity; the bottom of the cavity is provided with a slide valve hole channel communicated with the outside, and a one-way slide valve is arranged in the slide valve hole channel; the fan comprises a fan shaft and fan blades; the fan shaft is a hollow shaft, and meanwhile a plurality of small holes are formed in gaps where the fan shaft and the fan blades are connected. The connecting base covers the open cavity, the fan shaft penetrates through the connecting base to be in driving connection with the motor, and the fan blades are arranged in the open cavity. One end of the liquid injection hole channel is communicated with the internal hollow part of the fan shaft, and the other end of the liquid injection hole channel is communicated with the liquid injection assembly. The problem of rapid volatilization of anesthetic is solved, and the anesthetic delivery amount can be accurately controlled.

Description

technical field [0001] The invention belongs to the technical field of liquid evaporation, in particular to a centrifugal acceleration evaporation device. Background technique [0002] Precise control of the concentration of anesthetics is a major trend in the development of electronic vaporizers. Whether the traditional anesthesia evaporator is a mechanical evaporator or an electronic evaporator, the volatilization of the anesthetic is carried out in the evaporation tank. The way to control the concentration of the anesthetic is to divide the fresh gas into two paths, and the two paths of gas are equipped with control valves, and the distribution ratio of the air flow is controlled by adjusting the opening of the two valves. The gas entering the bypass evaporator will take away the anesthetic to realize the control of the concentration of the anesthetic. This method of controlling the concentration has poor accuracy and is not easy to control. [0003] Chinese invention ...
