[0046] like Figures 7 and 8As shown, the self-cleaning mechanism is arranged inside the dust cover 104 for cleaning the suction nozzle 1. The self-cleaning mechanism includes a liquid storage tank 201, a pressing nozzle 202, a pressing seat 203 and a wiping sleeve 209. The liquid storage tank 201 can be lifted and lowered inside the dust cover 104. The dust cover 104 is fixedly connected to a support plate 204. The liquid storage tank 201 is mounted on the support plate 204 through a return spring 205 and a telescopic rod. Physiological saline is contained in the liquid storage tank 201. The pressing nozzle 202 is mounted at the bottom of the liquid storage tank 201. The bottom end of the pressing nozzle 202 is fixedly connected to a pressing column 206. The pressing column 206 contacts the top of the upper shell 102. The bottom end of the pressing column 206 is fixedly connected to a positioning block 207. The upper shell The top of the liquid storage bin 201 and the inner bottom wall of the dust cover 104 are tightly attached to each other under the support of the return spring 205. The pressing seat 203 is at the highest position. After the patient has finished inhaling, the dust cover 104 is snapped onto the upper shell 102 to seal the suction nozzle 1 and reduce the entry of external dust and impurities. At this time, the positioning block 207 is located inside the positioning groove to support the pressing column 206, ensuring the stability of the pressing column 206 and the dust cover 104. The pressing seat 203 is pressed, and the pressing seat 203 drives the liquid storage bin 201 and the pressing nozzle 202 to descend, and the return spring 205 is pressed. 05 is compressed, and the upper shell 102 blocks the positioning block 207 and the pressing column 206, thereby squeezing the pressing nozzle 202, and the liquid in the liquid storage tank 201 is sprayed out through a small nozzle under the action of pressure. Since the diameter of the nozzle is very small, the flow rate of the liquid will increase sharply when passing through the nozzle. According to Bernoulli's principle, the pressure around the liquid will decrease at this time, while the air pressure outside the liquid storage tank 201 is relatively high. Under the action of the pressure difference, the air will be sucked into the nozzle and mixed with the liquid to form a mist, thereby spraying the physiological saline in the form of a mist at the suction nozzle 1. The inlet of the pipette connected to the pressing nozzle 202 is located at the lower position of the liquid storage tank 201, so that the physiological saline at the lower position of the liquid storage tank 201 can be sprayed out. After pressing, release the bottle. The pressing seat 203 is opened, and the liquid storage bin 201, the pressing seat 203 and the pressing nozzle 202 are raised and returned to their original positions under the action of the return spring 205. In order to observe the amount of physiological saline, an observation port 2 is provided on the dust cover 104, and a transparent observation window 208 is installed inside the observation port 2. The liquid storage bin 201 is also made of a transparent material. The liquid in the liquid storage bin 201 can be observed visually through the observation port 2. The wiping sleeve 209 can be raised and lowered and rotatably arranged inside the dust cover 104. The dust cover 104 is connected to the drive bin 210. The drive bin 210 is internally installed with an electric cylinder 211. The output end of the electric cylinder 211 is fixedly installed with a cleaning motor 212, and the wiping sleeve 209 is fixedly connected to the output end of the cleaning motor 212.The wiping sleeve 209 is located above the suction nozzle 1. A wiping pad 213 is installed inside the wiping sleeve 209. The switches of the electric cylinder 211 and the cleaning motor 212 are set below the pressing seat 203. After pressing the pressing seat 203, the electric cylinder 211 and the cleaning motor 212 are turned on. The electric cylinder 211 drives the wiping sleeve 209 to descend, and the wiping pad 213 is in close contact with the surface of the suction nozzle 1. The cleaning motor 212 drives the wiping sleeve 209 and the wiping pad 213 to rotate around the suction nozzle 1 to clean the suction nozzle 1. At the same time, the physiological saline solution has a certain degree of disinfection and sterilization effect. After rotating to a certain angle, the cleaning motor 212 stops working, and the electric cylinder 211 wipes the sleeve 209 and rises to complete the cleaning and disinfection of the suction nozzle 1.

[0047] To facilitate the replacement of the wiping pad 213, an iron sheet 214 is fixedly connected to the top of the wiping pad 213, and a magnet 215 is installed on the inner top wall of the wiping sleeve 209. The top of the iron sheet 214 is fixedly connected to a limiting rod 216, and a limiting groove matching the limiting rod 216 is provided on the inner top wall of the wiping sleeve 209. Through the mutual attraction between the iron sheet 214 and the magnet 215, the wiping pad 213 can be disassembled and replaced more conveniently. At the same time, when the wiping pad 213 is installed inside the wiping sleeve 209 through the iron sheet 214, the limiting rod 216 is inserted into the inside of the limiting groove, and the wiping pad 213 can rotate synchronously with the wiping sleeve 209 to ensure the cleaning effect of the suction nozzle 1.

[0048] In order to ensure the water absorption effect of the wiping pad 213, a heater 15 is installed on the wiping sleeve 209. After wiping is completed, the wiping sleeve 209 and the wiping pad 213 rise, and the heater 15 is powered on to generate heat, thereby heating the wiping sleeve 209 and the wiping pad 213 and drying the wiping pad 213 to ensure the water absorption effect of the wiping pad 213, thereby keeping the suction nozzle 1 dry after cleaning.

[0049] It should be noted that a power supply for supplying power to the electric cylinder 211 , the cleaning motor 212 and the heater 15 is installed inside the dust cover 104 , and a power supply for supplying power to the micro stepping motor 6 is installed inside the inner cavity 101 .

[0050] The working principle or usage process of the soft mist inhalation device is as follows:

[0051] When in use, unscrew the lock cap 16 through the access port to open the medicine compartment 5, push the medicine bottle 2 into the medicine compartment 5, insert the straw into the interior of the medicine bottle 2, and tighten the lock cap 16 to fix the medicine bottle 2;

[0052] When the medicine needs to be inhaled, the dust cover 104 is removed, the patient holds the mouthpiece 1 in his mouth, and presses the up button 9 to control the micro-stepping motor 6 to drive the screw 8 to rotate, so that the medicine chamber 5 drives the medicine bottle 2 upward, and the pressure difference is used to make the medicine flow through the needle tube 4 and press into the movement 3, where it is atomized and finally sprayed out, completing the inhalation of the soft mist;

[0053] After suction, the dust cover 104 is buckled onto the upper shell 102, and then the pressing seat 203 is pressed. The pressing seat 203 drives the liquid storage tank 201 and the pressing nozzle 202 to descend, compressing the return spring 205. The upper shell 102 blocks the positioning block 207 and the pressing column 206, thereby squeezing the pressing nozzle 202 and spraying the physiological saline in the liquid storage tank 201 onto the surface of the suction nozzle 1. The electric cylinder 211 drives the wiping sleeve 209 to descend so that the wiping pad 213 and the surface of the suction nozzle 1 are in close contact. The cleaning motor 212 drives the wiping sleeve 209 and the wiping pad 213 to rotate to clean and disinfect the suction nozzle 1. Then the electric cylinder 211 drives the wiping sleeve 209 to rise, and the heater 15 heats and dries the wiping sleeve 209 and the wiping pad 213.

[0054] The pointing position of the pointer 13 and the dial 12 can be observed through the observation port 1, so as to observe the usage of the medicine. When the medicine bottle 2 needs to be replaced after the medicine is used up, the lock cover 16 is unscrewed and the down button 10 is pressed. The micro-walking motor rotates in the opposite direction, driving the screw 8 to rotate, and then the medicine chamber 5 drives the medicine bottle 2 to move downward until the lock cover 16 completely exceeds the lower surface of the inner cavity 101. The lock cover 16 is rotated, the lock cover 16 is removed, the medicine bottle 2 is taken out, and a new medicine bottle 2 is replaced.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
