The outer circle profile of the porous sleeve 2 is cylindrical and a chord-shaped area is cut off, and the inner cavity of the evaporation seat 5 is matched with the profile of the porous sleeve 2. The reset elastic piece 8 is a reset spring.
In this embodiment, an electronic evaporation apparatus includes: a heating module, a vaporization assembly, and a valve assembly. The heating module comprises a heating core 4 and a heat insulation plate 3; the evaporation component comprises a porous sleeve 2, an evaporation seat 5, a ventilation joint 6, a valve seat 7 and the like, so that the anesthetic liquid is shunted and volatilized; the valve component 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 the opening and closing of the anesthetic liquid are realized.
In this embodiment, the porous sleeve 2 has a central axis hole in the middle, a strip groove is formed at one end of the central axis hole, and the valve element 9 slides near the strip groove in the central axis hole, so that the opening and the cutting of the anesthetic liquid can be realized. A plurality of small holes are distributed in the radial direction of the axial center hole of the porous sleeve 2, and the small holes penetrate through the excircle and the axial center hole. The anesthetic liquid enters from the axial hole and flows out from the small hole. The distribution of the small holes on the excircle of the porous sleeve 2 is provided with a strip-shaped groove.

The valve seat 7 is connected with the heat insulation plate 3 through a screw to press the porous sleeve 2 tightly.
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 and off of the opening of the anesthetic liquid medicine body at different positions, the anesthetic is opened or sealed in time, and the liquid inlet joint 1 is connected with the porous sleeve 2 through threads.

At the moment, the electromagnetic coil 10 is electrified to push the valve core 9 to move leftwards, the cylindrical sealing surface of the valve core 9 passes through the end face strip-shaped groove of the porous sleeve 2, so that the strip-shaped groove is communicated with the valve core groove, the anesthetic liquid inlet is opened, and the anesthetic enters 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 narcotic entering the wave flow passage is relatively dispersed, the surface area is greatly increased, and the evaporation of the narcotic is accelerated. Meanwhile, because the wave flow channel is adopted, the fresh gas can have positive impact relative to the anesthetic flowing out of the small hole, the air velocity on the surface of the anesthetic is increased, and the evaporation of the anesthetic is accelerated.
When anesthesia is not needed to be input, the electromagnetic coil 10 is powered off, and the valve core 9 is restored under the action of the reset elastic piece 8. At the moment, the sealing end face of the valve core 9 is separated from the end face strip-shaped groove 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 continuously flows in from the air inlet pipe of the ventilation joint 6 and flows out from the air outlet pipe, and the normal breathing of a patient is maintained.
The embodiment enables the anesthetic to flow in from the axis of the porous sleeve and then flow out from the small holes distributed on the periphery, so that the surface area of the anesthetic is greatly increased, and the residual anesthetic amount in the small holes is greatly reduced.
