The bottom of the chassis 21 is recessed to form a receiving groove 241 for receiving the second limiting member 25. The cover unit 3 closes the opening 13 of the tubular body 1 and includes a cover body 31 that closes the opening 13 and has a concave bowl shape. A plurality of holes 32 formed in the cover body 31 are disposed on the cover body. A spacer 33 that covers the holes 32 at the top and a plurality of engaging elements 34 that are disposed on the outer wall surface of the cover 31 and that are engaged with the convex portion 14 of the cylindrical body 1 are provided. The cover body 31 is formed with a centrally located positioning hole. The spacer 33 has an engaging portion 331 formed at the bottom and inserted into the positioning hole. In the present embodiment, the elastic member 4 is a compression spring disposed in the accommodating space 11 of the cylinder 1, and the two ends of the elastic member 4 abut against the top of the cylinder 1 and the chassis 24, respectively.

When the washing machine performs laundry washing, the washing tank 200 will oscillate up and down to apply pressure to the buffer device 100 of the washing tank. When the barrel 1 is forced to move downward, the elastic member 4 applies a reaction force to the The cylinder 1 is further transferred to the washing tank 200 to reduce the amplitude of the vibration of the washing tank 200. In addition, the air outside the cylinder 1 flows into the accommodating space 11 of the cylinder 1 through the holes 32 of the cover 31, but the gasket 33 blocks the inflow of outside air. Therefore, the upper air pressure is offset by the reaction force of the gasket 33, that is, the upper air pressure needs to be large enough to overcome the reaction force of the gasket 33 and flow into the cylinder 1 The accommodation space 11 is accommodated therein, whereby the resistance of the cylinder 1 when moving downward can be increased to reduce the vibration amplitude of the washing tank 200.

Similarly, when the cylinder 1 is moved upward by the force, the gasket 33 blocks the internal air of the cylinder 1 from flowing out of the holes 32 of the cover 31, so that the cylinder 1 can be moved upward when the cylinder 1 is moved upward. The resistance reduces the amplitude of the vibration of the washing tank 200. It should be noted that, in this embodiment, the buffer device 100 of the washing tub includes the elastic member 4 and the chassis 24 for carrying the elastic member 4. However, in other embodiments, the buffer device 100 of the washing tub is also The elastic member 4 and the chassis 24 need not be provided, and the air in the cylinder 1 can provide resistance to reduce the vibration amplitude of the washing tank 200.

In summary, the buffer device 100 of the washing tank of the present invention can block the air outside the cylinder 1 from flowing into the accommodating space 11 or block the inside of the cylinder 1 by the gasket 33 of the capping unit 3. The air flows out of the accommodating space 11, whereby the resistance when the cylinder 1 is moved up or down can be increased to reduce the vibration amplitude of the washing tank 200, so that the object of the present invention can be achieved.
