Shock absorber and laundry treating device including same

Abstract

The invention relates to the technical field of washing machines, in particular to a shock absorber and a washing machine including the shock absorber. The invention aims to solve the problems of invariable damping force and poor damping effect of the shock absorber in the prior art. For this purpose, the shock absorber of the present invention comprises: a sleeve having a first chamber; a plunger having a second chamber slidably inserted into the In the first chamber; the shock absorber also includes a throttling member disposed in the first chamber, the throttling member includes a pipe structure partially inserted into the second chamber, and the pipe structure Several first damping holes are provided on the pipe wall, and a recessed structure is provided on the outer wall of the pipe structure, and a part of the several first damping holes is opened / closed with the sliding of the plunger, so that The first chamber and the second chamber are communicated with each other via the first orifice in an open state. The damping force produced by the shock absorber of the invention is variable at any time and has high stability.

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 one of the indispensable household appliances in people's daily life. However, the washing machine will produce obvious vibration and noise during the washing and dehydration process, which affects the user experience to a certain extent. [0003] In order to solve the problem that the washing machine produces obvious vibration and noise during the washing and dehydration process, the invention patent application with the publication number CN105986407A discloses a "shock absorber, washing machine, and clothes dryer". Wherein, the sho...
