The front and rear impellers are both disc-shaped, mainly to prevent the dripping or direct throwing of the medicine adhered to the surface of the impeller, which may cause drug damage.
Impeller is one of the most important parts in spray, which directly affects the quality of spray The impeller consists of a front impeller and a rear impeller, which are connected by eight fixing pins. On the rear impeller, there are 1 on both sides of each pin hole 5mm thick shoulder to ensure a certain distance between the front and rear impellers after assembly. After installing the front and rear impellers, press one end of the micro motor shaft to allow the impellers to rotate and move.
The front and rear impellers are both disc-shaped, mainly to prevent the dripping or direct throwing of the medicine adhered to the surface of the impeller, which may cause drug damage. To make the atomized mist more uniform, 36 is engraved on the outer edge of the two impellers. A semi angular cone-shaped small tooth is used to reduce the adhesion of the thin film attached to the impeller surface and become the starting point of the mist point when throwing away, allowing the liquid to be thrown out in a regular manner along it.
One end of the anti liquid sleeve is a hole with a diameter of 7 millimeters, which is tightly fitted onto the front impeller shaft; The other end extends into the groove at the end of the motor casing to prevent the motor shaft from coming into contact with the liquid and rusting The anti liquid sleeve rotates at high speed together with the impeller, which can throw out the splashed liquid on it to prevent the liquid from seeping into the interior of the motor and causing corrosion. Lubricating grease can also be applied inside the anti liquid sleeve to increase bearing lubrication and improve the service life of the motor.
The nozzle bracket is shaped like a national column and fits inside the handle tube. Insert the medicine bottle holder into the upper fork. There are two circular holes with a diameter of 4 millimeters on the lower side of the fork, which are matched with five semi-circular grooves on the ear shoulder of the medicine bottle support, allowing the nozzle body to have five different rotation angles, which can be adjusted according to the operation requirements. There is a circular hole with a diameter of 3.2 millimeters inside the fork for threading wires.
