Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cleaning tools, especially a rubber cotton mop. BACKGROUND

[0002] The rubber cotton mop is a common ground cleaning tool, which has good water absorption performance and can be applied to various cleaning scenes, such as solid wood floor, multi-layer floor, tile and marble. The rubber cotton mop mainly comprises a mop rod, a pulling mechanism, a supporting seat and a rubber cotton head. A roller body for squeezing water from the rubber cotton head is arranged on the supporting seat. The rubber cotton head is connected to the mop rod through the pulling mechanism. The pulling mechanism moves up and down relative to the mop rod to drive the rubber cotton head to enter or exit between the roller bodies on the supporting seat, so as to squeeze and dehydrate the rubber cotton head. The roller body comprises a shaft rod and a water squeezing rod. The water squeezing rod is a hollow rod. A plurality of support ribs are arranged in the water squeezing rod in a radial direction. The support ribs form a shaft hole in the middle of the water squeezing rod. The water squeezing rod passes through the shaft hole. The water squeezing rod is fixed to the supporting seat through the shaft rod. The shaft hole formed by the support ribs is actually a polygon, which makes the coaxiality of the shaft rod and the water squeezing rod relatively poor, thereby increasing the resistance of the pulling mechanism and causing the dehydration process of the rubber cotton head to be not smooth enough. In addition, in order to facilitate demolding during processing, the support ribs inside the water squeezing rod are provided with a demolding chamfer, which gradually increases the inner diameter of the shaft hole from one end. Therefore, after the shaft rod passes through the shaft hole, the shaft rod and the water squeezing rod have a wobble gap at the large end of the shaft hole. When the rubber cotton head moves upward for squeezing and dehydration, the two ends of the water squeezing rod cannot rotate coaxially, and the shaft rod will squeeze the reinforcing ribs at the large end of the shaft hole, causing a loud noise during the squeezing and dehydration process.
