Accurate control of anesthetic concentration is a major trend in the development of electronic evaporators. The traditional anesthetic vaporizer, whether a mechanical vaporizer or an electronic vaporizer, is used for vaporizing anesthetic in an evaporating pot. The method for controlling the concentration of the anesthetic is to divide fresh gas into two paths, wherein the two paths of gas are provided with control valves, and the distribution ratio of the gas flow is controlled by adjusting the opening of the two valves. The gas entering the bypass evaporator takes away the anesthetic, so as to realize the control of the concentration of the anesthetic. This way of controlling the concentration is less accurate and not easily controllable.

The valve seat 7 is provided with an electromagnetic coil 10 for controlling the movement of the valve core. The outer circular contour of the porous sleeve 2 is cylindrical and is cut off into a chord-shaped area, and the inner cavity of the evaporation seat 5 is matched with the outer contour of the porous sleeve 2. The return elastic member 8 is a return spring.
In this embodiment, an electronic evaporation device includes: a heating module, an evaporation assembly, and a valve assembly. The heating module comprises a heating core 4 and a heat insulation plate 3; the evaporation assembly comprises a porous sleeve 2, an evaporation seat 5, a ventilation joint 6, a valve seat 7 and the like, so that the diversion and volatilization of anesthetic liquid are realized; the valve assembly comprises a liquid inlet connector 1, a porous sleeve 2, a valve seat 7, a spring 8, a valve core 9 and an electromagnetic coil 10, and can be used for opening and closing anesthetic liquid.
In this embodiment, the porous sleeve 2 has an axial hole in the middle, and a strip-shaped groove is formed at one end of the axial hole, and the valve core 9 slides near the strip-shaped groove in the axial hole, so that the opening and cutting of the anesthetic liquid can be realized. A plurality of small holes are distributed in the radial direction of the axis hole of the porous sleeve 2, and the small holes penetrate through the outer circle and the axis hole. The anesthetic liquid enters from the axle center hole and flows out from the small hole. The distribution of the small holes on the outer circle of the porous sleeve 2 is provided with a strip-shaped groove.
The outer circle outline of the evaporation seat 5 is cylindrical and is cut into a chord-shaped area, a through hole is formed in the axis of the evaporation seat, a cylindrical groove is formed in one end face of the evaporation seat, convex strips are distributed on the edge of the cylindrical groove, and the convex strips correspond to the strip-shaped grooves of the porous sleeve 2 one by one.
The specific assembly relation of the components of the embodiment is as follows:
the step shaft on one side of the porous sleeve 2 penetrates through the central hole of the evaporation seat 5, the strip-shaped grooves of the porous sleeve 2 are in one-to-one correspondence with the convex strips of the evaporation seat 5, and a wave gap is formed between the strip-shaped grooves of the porous sleeve 2 and the convex strips to serve as a wave-shaped gas channel for fresh gas to pass through. The valve seat 7 is connected with the heat insulation plate 3 through a screw to compress the porous sleeve 2.
After the evaporation seat 5, the porous sleeve 2 and the valve seat 7 are assembled, the valve core 9 penetrates through and compresses the reset elastic piece 8 to enter the axis of the porous sleeve 2, the electromagnetic coil 10 is connected with the valve seat 7 through a screw, the position of the valve core 9 is controlled by controlling the power-on and power-off of the electromagnetic coil 10, the valve core 9 can control the on-off of an anesthetic liquid opening at different positions, the anesthetic is timely opened or sealed, and the liquid inlet connector 1 is connected with the porous sleeve 2 through threads.

The specific working principle is as follows:
when a certain anesthetic concentration is required to be output, only the flow rate of the liquid anesthetic entering the liquid inlet connector 1 is required to be controlled. At this time, the electromagnetic coil 10 is electrified to push the valve core 9 to move leftwards, the cylindrical sealing surface of the valve core 9 is communicated with the valve core groove through the end surface strip-shaped groove of the porous sleeve 2, the anesthetic liquid inlet is opened, and the anesthetic enters into the small hole of the porous sleeve 2 under the pushing of the plunger pump and flows into the wave flow channel formed by the porous sleeve 7 and the evaporation seat 5 through the small hole. Because the porous sleeve 2 has more distributed small holes, the anesthetic entering the wave flow passage is relatively dispersed, the surface area is greatly increased, and the evaporation of the anesthetic is quickened. Meanwhile, because the flow channel is a wave flow channel, fresh gas can have opposite front impact on the anesthetic flowing out of the small hole, so that the air flow speed on the surface of the anesthetic is increased, and the evaporation of the anesthetic is accelerated.
When anesthesia does not need to be input, the electromagnetic coil 10 is powered off, and the valve core 9 is restored to the original position under the action of the reset elastic piece 8. At this time, the sealing end face of the valve core 9 is separated from the strip-shaped groove on the end face of the porous sleeve 2, and the liquid inlet of the anesthetic is sealed, so that the input of the anesthetic is stopped, fresh gas continues to flow in from the air inlet pipe of the ventilation joint 6 and flows out from the air outlet pipe, and normal breathing of a patient is maintained.
According to the embodiment, the anesthetic flows in from the axis of the porous sleeve and flows out from the small holes distributed on the periphery, so that the surface area of the anesthetic is greatly increased, and the residual anesthetic dosage in the small holes is greatly reduced.
