[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 5This utility model provides a technical solution: an anesthetic spray device, including a base 1, an electric push rod 2 mounted on the top of the base 1, a medicine box 3 connected to the output end of the electric push rod 2, a medicine storage container 4 rotatably connected inside the medicine box 3, a plurality of placement slots 5 inside the medicine storage container 4, and a dispensing port 6 at the bottom of each of the placement slots 5 inside the medicine storage container 4, with medicine bottles 7 placed inside each of the placement slots 5. When the electric push rod 2 pushes the medicine box 3 and the medicine storage container 4 to repeatedly rise and fall, the medicine bottles 7 shake accordingly, which helps to evenly distribute their internal components. An inlet / outlet 8 is located at the bottom of one of the dispensing ports 6 inside the medicine box 3. A water pump 9 is mounted on one side of the medicine box 3, and a drain pipe 10 is connected to the output end of the water pump 9. One end of the 10 is connected to an atomizing nozzle 11. The input end of the water pump 9 is connected to a guide tube 12. One end of the guide tube 12 is connected to an inlet tube 13. One end of the inlet tube 13 is connected to a needle 14. A positioning cover 15 is installed on the top of the base 1 and at the bottom of the inlet / outlet 8. The positioning cover 15 has a positioning groove 16 that mates with the needle 14. By operating the electric push rod 2, the medicine box 3 and the medicine reservoir 4 are raised and lowered, which facilitates the adjustment of the height of the medicine bottle 7. This allows the needle 14, located inside the positioning cover 15, to pass through the medicine dispensing port 6 and pierce into the medicine bottle 7. With the operation of the water pump 9, the anesthetic is extracted and then sprayed out by the atomizing nozzle 11. A flow meter 21 is installed on one side of the guide tube 12. The sensing end of the flow meter 21 is located inside the guide tube 12. Measuring the flow rate and volume of the anesthetic helps to accurately control the dosage. A locking bolt 17 is threaded onto one side of the positioning cover 15, with one end extending into the positioning groove 16. Rotating the locking bolt 17 allows one end to press or release the needle 14, facilitating its fixation and disassembly. A sealing cap 22 is threaded onto the inside of the medicine box 3 and at the top of the medicine reservoir 4. The bottom of the sealing cap 22 fits against the medicine bottle 7. Opening or closing the medicine box 3 presses against the sealing cap 22, preventing the medicine bottle 7 from being pushed out by the needle 14. A self-locking motor 18 is fixedly installed inside the medicine box 3. The output of the self-locking motor 18 is connected to the medicine reservoir 4, driving the reservoir 4 to rotate, facilitating the alignment of different medicine bottles 7 with the inlet / outlet 8 and the needle 14. The medicine tank 3 replaces manual labor for loading medicine bottles 7. A control panel 23 is installed on the outer wall of the medicine tank 3. A shelf 19 is installed on one side of the medicine tank 3, above the water pump 9. The shelf 19 has an internal limiting groove 27 that mates with the drain pipe 10. The shelf 19 has an L-shaped structure, which supports the atomizing nozzle 11 and helps prevent it from falling off. A winding rod 20 is installed on one side of the base 1, between the water pump 9 and the shelf 19, to facilitate winding and organizing longer sections of the drain pipe 10. Two first supports 24 are installed on the top of the base 1, on both sides corresponding to the electric push rod 2. A second support 25 is slidably connected inside each of the two first supports 24, and one end of the second support 25 is connected to the medicine tank 3.Both first supports 24 have internally installed telescopic springs 26. One end of the telescopic spring 26 is connected to the second support 25. The connection between the second support 25 and the medicine box 3, along with the deformation of the first supports 24, facilitates support for the medicine box 3, making it more stable. The height of the medicine container 4 is less than the height of the medicine bottle 7. This height difference between the medicine bottle 7 and the medicine container 4 facilitates the removal of the medicine bottle 7.

[0024] In summary, during use, the electric push rod 2 pushes the medicine box 3 and its internal medicine reservoir 4 to repeatedly rise and fall, causing the dispensing ports 6 in the multiple placement slots 5 inside the medicine reservoir 4 to shake. The electric push rod 2 then lowers the medicine box 3. Since the bottom inlet / outlet 8 of the medicine box 3 aligns with the dispensing port 6 at the bottom of one of the placement slots 5 inside the medicine reservoir 4, the needle 14 located in the positioning cover 15 below the inlet / outlet 8 aligns with the medicine bottle 7. As the medicine reservoir 4 descends, one end of the needle 14 passes through the dispensing port 6 and the aluminum foil at one end of the medicine bottle 7, and pierces into the medicine bottle 7. The water pump 9 operates, guiding the anesthetic in the medicine bottle 7 through the needle 14 from the inlet pipe 13 and the guide pipe 12 to the outlet pipe 10, and then to the atomizing nozzle. 11 is sprayed onto the location requiring anesthesia. At the same time, the flow meter 21 on the guide tube 12 measures the flow rate and flow of the anesthetic. Similarly, after the anesthetic in the medicine bottle 7 is used up, the electric push rod 2 pushes the medicine box 3 upward again, so that the needle 14 is pulled out from the medicine bottle 7 above. The self-locking motor 18 drives the medicine reservoir 4 to rotate, moving the remaining medicine bottle 7 above the inlet and outlet 8. The operation is repeated. The electric push rod 2 drives the medicine box 3 and the medicine reservoir 4 to descend, and the needle 14 is inserted into the new medicine bottle 7 again for use. As needed, make sure to pass the drain tube 10 through the limiting groove 27 in the shelf 19 so that the atomizing nozzle 11 is placed on the shelf 19, and wrap the longer part of the drain tube 10 around the winding rod 20.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
