Detailed ways

The present invention is described in further detail below:

The cleaning body 47 can be of various types, such as collodion blocks, sponge blocks, mops, etc., and can be made of plastic (polymer) foam, microfiber, cotton cloth and other materials. The collodion block is exemplified as the cleaning body 47 below.

A cleaning bucket of the present invention includes a bucket body 29 and a bucket cover 30. The bucket cover 30 is provided with a water squeezing port 3 for the mop head 2 to pass through and a water squeezing assembly arranged along the water squeezing route. The water squeezing assembly includes a parallel four-bar linkage Mechanism, water squeezing part, one side of the parallel four-bar linkage mechanism is used as the fixed side, the other side is the swing side, the swing side is provided with a water squeezing part, and the parallel four-bar linkage mechanism supports the up and down translation movement of the water squeezing part for realizing Squeeze and wash the cleaning body 47 of the mop head 2 .

In this example, the cleaning bucket is provided with only one squeezing port 3, and the mop head 2 shares the same squeezing port 3 and the bucket body 29 when cleaning or squeezing water. The same barrel 29 is used for the water squeezing operation.

The whole formed by the combination of the parallel four-bar linkage mechanism and the water squeezing part can be called a water squeezing assembly. A parallelogram linkage is also called a parallelogram mechanism.

The fixed side of the parallel four-bar linkage mechanism is arranged obliquely backward from top to bottom, and the two parallel pendulum rods of the parallel four-bar linkage mechanism are in a horizontal state in an initial state.

The parallel four-bar linkage mechanism is a self-resetting parallel four-bar linkage mechanism. After the self-resetting parallel four-bar linkage mechanism is reset, the cross-section of the squeezing port 3 is in a small or minimum condition. In this example, the parallel four-bar linkage mechanism The swing bar swings upward to the horizontal state, at this time, the size of the opening between the water squeezing part and the opposite side is taken as the cross-sectional size of the water squeezing port 3 after reset. Since the pressing parts on the working face of the water squeezing part are set in a gradual retreat, the cross-sectional size of the squeezing port 3 increases sequentially from top to bottom.
