[0035] like Figure 1-Figure 8As shown, the principle of the control system of the portable washing machine provided in this embodiment is as follows: when using the device, the protective shell 1 should be taken out first, and then the front and rear ends of the washing drum 3 are embedded with the shock-absorbing and buffering control system 2, and then the shock-absorbing and buffering control system 2 is fixed to the inner wall of the protective shell 1 by the rear bolts, and then the driving motor 17 is installed, ensuring that the belt 20 is completely embedded in the groove 21 and will not slip off, and then the first cover 22 is fixed to the rear end opening of the protective shell 1 by bolts, and at the same time, the second cover 23 is fixed to the front end opening of the protective shell 1 by bolts, and after tightening the bolts, a rubber plug can be installed at the nut to prevent the bolts from rusting in a humid environment, and then the sealing door 26 is opened to check whether the rubber sleeve 25 is extended and embedded to the inner wall of the washing drum 3, and it is necessary to ensure that the rubber sleeve 25 is sealed and fitted with the inner wall of the edge of the washing drum 3;

[0036] After installation, the sealing door 26 is opened, and the clothes to be washed are placed in the washing drum 3. The driving motor 17 drives the washing drum 3 to rotate and wash through the first pulley 18, the second pulley 19 and the belt 20; when the washing drum 13 starts to rotate or the clothes in the washing drum 3 are placed unevenly, it will shake violently. At this time, the shaking of the washing drum 13 will make centrifugal motion, and the open end of the washing drum 3 will be squeezed outward. At the same time, the hydraulic shock absorbing rod 5 in the shock absorbing and buffering control system 2 begins to play a role, and the squeezed hydraulic shock absorbing rod 5 will shrink. At this time, the pressure rod 29 in the hydraulic shock absorbing rod 5 will absorb most of the pressure, and cause the pressure rod 29 to squeeze the hydraulic oil, so that the hydraulic oil under the buffer block 10 passes through the oil inlet 16 Entering above the buffer block 10, the first sleeve 7 enters into the second sleeve 8. At this time, the shock-absorbing spring 11 between the first sleeve 7 and the hydraulic oil storage tube will rebound elastically, so that the pressure rod 29 extends, and at the same time, the hydraulic oil above the buffer block 10 enters below the buffer block 10 through the oil inlet hole 16. The first sleeve 7 will also extend from the second sleeve 8. The shaking caused by the operation of the washing drum 3 will be consumed in the process of the hydraulic shock-absorbing rod 5 being squeezed and elastically offset; several hydraulic shock-absorbing rods 5 around the washing drum 3 will offset and consume the force generated by the shaking, ensuring that the washing drum 3 will not shake during movement, so that the washing drum 3 in operation will not shake, and then the device in operation will not shake violently.
