[0031] Working principle of the present invention: When the present invention is working, the liquid medicine is put into the mixing chamber 101 through the first medicine delivery tube 3, and the solid medicine is put into the discharge trough 1301 through the second medicine delivery tube 4, and then the medicine outlet head 2 is sent into the patient's mouth, and the air pump 24 is turned on to draw the outside air into the air inlet chamber 19, and then enter the air bag 5. After the air bag 5 is filled, it swells and fits closely to the patient's mouth. At the same time, as the gas enters the air inlet chamber 19, the air pressure increases, pushing the fourth piston 21 to slide, driving the third piston 20 to slide, and the left side of the third piston 20 The space of the suction chamber 18 becomes larger, so that the pressure in the suction cup 6 becomes smaller, and the suction cup 6 adsorbs the patient's mouth. The suction cup 6 adsorbs the patient's mouth, and at the same time, the air bag 5 is inflated and close to the patient's mouth, so that the patient's mouth is sealed and protected to avoid the waste of liquid medicine flowing out. In addition, the air in the air inlet chamber 19 enters the blind hole 104 through the channel, pushing the first piston 7 to slide, so that the plug 8 is separated from the drug delivery channel 103, and the drug in the mixing chamber 101 enters the drug delivery chamber 102 through the drug delivery channel 103, and then is fed into the patient's mouth through the drug outlet head 2.

[0032] During the sliding process of the push plate 25 pushing the push rod 12, the sealing baffle 17 blocks the first drug delivery tube 3 to prevent the push rod 25 from being pushed too fast and causing the liquid medicine to overflow from the first drug delivery tube 3; the solid medicine enters between the second piston 13 and the grinding disc 14 from the discharge trough 1301 through the feed port 1302, and as the push rod 12 slides in the mixing chamber 101, the grinding disc 14 moves relative to the lead screw 11, and under the cooperation of the lead screw 11 and the grinding disc 14, the grinding disc 14 rotates relative to the second piston 13 to grind the solid medicine. At the same time, the ground solid medicine and liquid medicine are mixed in the mixing chamber 101, and the stirring panel 15 stirs the mixed medicine to ensure that the medicine is evenly mixed.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
