[0009] Preferably, the pushing mechanism includes a first operating cylinder, a first support ring fixedly connected to the inner wall of the first operating cylinder, a reciprocating threaded cylinder slidably connected to the inner side wall of the first support ring, a second support ring fixedly connected to the inner wall of the first operating cylinder, a motor fixedly connected to the inner wall of the second support ring, a threaded column fixedly connected to the movable end of the motor, the side wall of the threaded column being threadedly connected to the inner wall of the reciprocating threaded cylinder, and the side wall of the drug delivery cylinder away from the shell cover being threadedly connected to the inner wall of the first operating cylinder.

[0010] Preferably, a storage battery is fixedly connected to the inner wall of the first operating cylinder, a circuit board is installed inside the first operating cylinder, and a button is provided on the circuit board. The motor, storage battery, circuit board and button are electrically connected.

[0011] Preferably, a switch button is installed on the side wall of the first operating cylinder facing the button, and the side wall of the switch button is in contact with the side wall of the button. A charging port is installed at the bottom of the first operating cylinder, and the charging port is electrically connected to the battery.

[0012] Preferably, the pushing mechanism includes a second operating cylinder, a push rod is slidably connected to the inner wall of the second operating cylinder, a handle is fixedly connected to the side wall of the push rod away from the second operating cylinder, and the side wall of the drug delivery cylinder away from the shell cover is threadedly connected to the inner wall of the second operating cylinder.

[0013] This utility model has the following beneficial effects:

[0014] 1. A first operating cylinder and a motor are set up. When needed, the motor is driven to rotate clockwise, which drives the threaded column to rotate clockwise and moves the reciprocating threaded cylinder upward. At this time, the liquid medicine can be squeezed out to complete the application to the patient's nasal passages or some natural passages. The speed and time of the motor can control the speed and amount of liquid medicine applied. The operation is simple and avoids the use of syringes in existing technologies, which do not require the patient to operate themselves and are not easy to control the amount of medicine used.

[0015] 2. The addition of a drug delivery cartridge allows for the storage of liquid drugs, making them readily available for use later.

[0016] 3. The addition of a push rod and a second operating cylinder allows users to administer medication manually without the need for electric dispensing, thus increasing the applicator's usability. Attached Figure Description
