Technical Field

The invention relates to a wringing device for bilaterally squeezing foam cotton in a mop head, which can be used on a cleaning tool comprising a cleaning barrel and can also be used on a self-wringing foam cotton mop, wherein the foam cotton can be a collodion cotton head, a sponge head or the like. The invention also relates to a cleaning tool with the water squeezing device and a cleaning barrel, and a self-water-squeezing foam cotton mop with the water squeezing device.

Background

The invention is specially designed for a cleaning tool of a foam cotton mop or a self-squeezing foam cotton mop, and is provided with a water squeezing device, wherein the cleaning tool comprises a cleaning barrel and a mop head which is rotatably connected to the lower end of a mop rod and is provided with foam cotton, and the water squeezing device is arranged on the cleaning barrel. The self-squeezing foam cotton mop is characterized in that the squeezing device is arranged on the mop rod and can slide up and down along the mop rod. The squeezing device has similar structure, the squeezing component in the squeezing device squeezes the foam cotton on the mop head which moves up and down through the squeezing device, and the foam cotton has larger size in the thickness direction due to the characteristics of the foam cotton material, so that two squeezing modes are adopted for the squeezing structure of the foam cotton mop.

A first water squeezing mode: the squeezing component only squeezes the bottom surface of the foam cotton, and the Chinese patent application with the application number of CN201811267670.4 discloses a first water squeezing mode, namely a collodion mop squeezing barrel, and the Chinese patent application with the application number of CN201710920255.3 discloses a cleaning barrel and a collodion mop for cleaning the collodion mop.

A second water squeezing mode: the two squeezing parts can simultaneously squeeze the left and right sides of the foam cotton, and a second water squeezing mode is disclosed in the Chinese utility model patent with the patent number ZL201821624855.1, which is applied by the applicant.

The two water squeezing modes have the characteristics respectively, and compared with the first water squeezing mode, the second water squeezing mode has better water squeezing effect and relatively labor-saving water squeezing operation. However, the cleaning tool of the second prior art has the following commonalities: 1. the foaming cotton is fixed on the mounting plate in a bonding mode, the mounting plate is connected to the mop plate, or the foaming cotton is bonded on the mop plate; 2. the squeezing surfaces of the two squeezing parts, which are contacted with the foam cotton, are arranged in parallel at intervals, namely the width of a squeezing channel between the two squeezing parts along the axial direction of the squeezing parts (basically deviated to the thickness direction of the foam cotton) is basically consistent, and the bottom surface of the foam cotton has a certain radian. When the mop head passes through the extrusion opening of the extrusion device, the extrusion force of the extrusion part on the left side and the right side of the foam cotton along the thickness direction is basically the same, or the extrusion force of the extrusion part on the left side and the right side of the foam cotton close to the mop plate is slightly larger than that in the direction far away from the mop plate, water is extruded to be dry, the extrusion force needs to be larger, and the problem that the bonding surface of the foam cotton is easily torn to cause product damage is caused.
