[0032] Workflow: Before use, power on the device. When installing the blade plate 6, first install the connecting threaded cylinder 1 on the handle, then install the blade plate 6. Press the connecting plates 52 on both sides of the fixed frame 2. At this time, the positioning rod 51 slides inside the fixed frame 2 and the partition 4, and the retaining frame 53 moves with the positioning rod 51. The positioning spring 54 on one side of the round plate 55 is compressed. Then, insert the mounting plate 8 on the rear side of the blade plate 6 into the inside of the fixed frame 2. Release the connecting plate 52. The positioning spring 54 returns to its original position, causing the positioning rod 51 to slide inside the fixed frame 2 and the partition 4. The retaining frame 53 is inserted into the retaining groove 9 and engages with the retaining groove. The installation of the blade plate 6 is completed by snapping together 9. The positioning component 5 makes the installation of the blade plate 6 more convenient and saves installation time. The next step is to install the foaming component 11.

Then, unscrew the plug 115 from the inside of the threaded tube 114, add an appropriate amount of cleaning fluid into the inside of the foaming shell 112 through the threaded tube 114, screw the plug 115 back into the inside of the threaded tube 114, and start the motor. 111. The output shaft of motor 111 rotates, driving the agitator 113 to rotate. At this time, the cleaning solution is agitated into foam by the high-speed rotating agitator 113. The cleaning foam is discharged through the discharge hole 116 and the round hole 1184. Now, press and move the soft plate 1182 against the beard. The massage particles 1183 cooperate with the soft plate 1182 to evenly spread the foam between the beard hairs. The foaming component 11 makes foaming the cleaning solution more convenient and saves foaming time. The massage component 118 improves the comfort of beard cleaning. Next, remove the foaming component 11 and use the blade 6 to shave. The shaved beard enters the inner side of the fixing frame 2 through the gap between the blades 7 and falls out through the through groove 3. This design can prevent the beard from clogging the inside of the device and increase the convenience of use. After use, place the fixing frame 2 under the tap to rinse. The remaining beard can be discharged through the gap between the blades 7 and the through groove 3. Unscrew the plug 115 from the inside of the threaded tube 114. Water enters the inside of the foaming shell 112 through the upper threaded tube 114 and is discharged through the lower threaded tube 114.
