Embodiment Construction

[0043] figure 1 It is a schematic perspective view of an adjustable damping boom 10 according to an embodiment of the present invention. Such as figure 1 As shown, the adjustable damping boom 10 according to the embodiment of the present invention generally includes a long boom 1 and a cylinder 2.

[0044] The cylinder 2 defines a cavity for containing magnetorheological fluid. The cavity is provided with a piston 3 which can reciprocate along the axial direction of the cavity. The bottom end of the elongated boom 1 is inserted into the cylinder 2 from the upper end of the cylinder 2. The piston 3 and the elongated boom 1 are fixedly connected in the cavity. Further, the piston 3 can be fixedly connected to the bottom end of the elongated boom 1. The piston 3 is provided with a coil 32 capable of generating a magnetic field when energized, and a liquid flow channel 31 penetrating the piston 3 in the axial direction. That is, the magnetorheological fluid on one side of the pis...

Abstract

The invention provides a damping-adjustable lifting rod for a pulsator washing machine and the pulsator washing machine with the damping-adjustable lifting rod. The damping-adjustable lifting rod comprises a cylinder body, a cavity for containing magnetorheological fluid is defined in the cylinder body, a piston doing reciprocated movement in the axial direction of the cavity is arranged in the cavity, the piston is provided with a coil capable of generating a magnetic field during electrification and a liquid flow passage penetrating the piston in the axial direction, and the fluidity of the magnetorheological fluid in the liquid flow passage is changed by changing the size of the current in the coil. The bottom end of the long lifting rod is inserted into the cylinder body from the upper end of the cylinder body to be fixedly connected with the piston, a top installation base is arranged at the top end of the long lifting rod, and therefore the damping-adjustable lifting rod is lifted to a lifting base of a machine shell of the pulsator washing machine. A positioning part extending upwards is formed at the upper end of the cylinder body so as to be matched with a damping base of a washing outer barrel of the pulsator washing machine, and therefore the washing outer barrel is lifted on the damping-adjustable lifting rod under the effect of the gravity. The damping-adjustable lifting rod is particularly suitable for the pulsator washing machine.

Description

Technical field [0001] The present invention relates to the technical field of shock absorption, in particular to an adjustable damping suspension rod for a pulsator washing machine and a pulsator washing machine with the adjustable damping boom. Background technique [0002] As we all know, during the working process of the washing machine, due to the unbalanced load and centrifugal force of the washing items, vibration cannot be avoided. The shock absorption device generally used in the current pulsator washing machine is an adjustable damping boom that connects the casing of the washing machine and the washing outer tub. The sliding friction is formed by the up and down movement of the friction parts on the adjustable damping boom, and friction is generated. Shock absorption. The disadvantage of this structure is that the friction force obtained is almost constant regardless of the amount of laundry, and the change and adjustment of damping cannot be realized. [0003] Magneto...
