Abstract

The invention relates to the technical field of washing machines, in particular to a shock absorber and a washing machine comprising the shock absorber. The invention aims to solve the problems of invariable damping force, poor damping effect and the like of the shock absorber in the prior art. To this end, the shock absorber of the invention comprises a sleeve having a first chamber; a plunger having a second chamber is slidably inserted into the first chamber; the shock absorber also comprises a throttling piece arranged in the first chamber, the throttling piece comprises a pipe structure partially inserted into the second chamber and a sliding block freely sliding in the pipe structure, the pipe structure is provided with a plurality of damping holes, a part of the damping holes is inan open / closed state with the sliding of the plunger, and the first chamber and the second chamber communicate with each other by means of the damping holes in the open state. The damping force generated by the shock absorber can be changed at any time, and the stability is high.

Description

technical field [0001] The invention relates to the technical field of clothes treatment, in particular to a shock absorber and a clothes treatment device including the shock absorber. Background technique [0002] The washing machine is a clean electrical appliance that uses electric energy to wash clothes. With the acceleration of the pace of life and the improvement of people's requirements for living comfort, the washing machine has become an indispensable household appliance in people's daily life. However, the washing machine can produce obvious vibration and noise during washing, rinsing and dehydration, which brings some inconvenience to people's normal life. [0003] On solving the problem of excessive vibration and noise when the washing machine works, the invention patent application with the publication number CN105986407A discloses a "shock absorber and washing machine, clothes dryer". Wherein, the shock absorber includes a sleeve with an open end and a first p...
