Shock absorber and laundry treatment apparatus including shock absorber

Abstract

The invention relates to the technical field of washing machines, in particular to a shock absorber and a laundry treatment apparatus including the shock absorber. The invention aims to solve the problems that the damping force of the shock absorber in the prior art cannot be changed, the damping effect is poor due to the failure of the shock absorber, and the like. To this end, the shock absorberof the invention comprises a sleeve having a first chamber; a plunger having a second chamber is slidably inserted into the first chamber; one end of the second chamber, which is inserted into the first chamber, is fixedly connected or integrally provided with a baffle plate, a throttling piece which penetrates through the baffle plate and partially extends into the second chamber is also arranged in the first chamber, the throttling piece is provided with a plurality of first damping holes, one part of the first damping holes is in an 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 first damping holes in the open state. Through the arrangement of the throttling piece and the baffle plate, the damping force generated by the shock absorber can be changed at any time, the stability is high, and the shock absorber can be popularized and used on a large scale.

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 people's high requirements for living comfort, the washing machine has become an indispensable household appliance in people's daily life. However, the washing machine can make a lot of 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 and clothes dryer". Wherein, the shock absorber includes a sleeve with an open end and a first plunger. One e...
