Description

Technical Field

[0001] The utility model belongs to the technical field of mops and relates to a water squeezing structure of a cleaning head of a collodion mop. Background Art

[0002] The cleaning head of the cotton mop is a common tool for daily mopping and washing. It needs to squeeze water when in use. In order to avoid direct contact with hands, a matching squeezing bucket is currently used to squeeze water. There are generally two ways to squeeze water. One is to squeeze water by pressing the whole body.

[0003] For example, a water squeezing device for a cotton working head disclosed in a Chinese patent document [Application No. 201910892217.0], etc., this method can only be used for a cotton mop, and the water is squeezed out by flattening the cotton head as a whole after absorbing water. In order to flatten the cotton head as a whole, a lot of pressure is required, which cannot be completed by manpower alone. Therefore, an auxiliary clamping structure needs to be provided in the above methods, which makes the overall structure complicated and the cost higher; the other method is to scrape water vertically, such as a manual scrubbing and squeezing mop bucket disclosed in a Chinese patent document [Application No. 202010908216.3], a cotton mop cleaning device [Application No. 201920863797 .6], etc. This method requires first rotating the mop cleaning head to a vertical state, then vertically inserting the mop cleaning head and squeezing water through a squeezing roller. In this process, the part in contact with the squeezing roller can squeeze water, but the squeezed water will flow downward, and the part of the vertically arranged mop cleaning head located below the squeezing roller is the part where water has been squeezed, and its water absorption capacity is better. Therefore, the water squeezed out at the squeezing roller will be reabsorbed by the part of the mop cleaning head located below the squeezing roller, resulting in low squeezing efficiency. It takes multiple operations to complete the squeezing of water. At the same time, when moving up and down during use, the squeezing roller is pressed against the mop cleaning head, that is, it takes a lot of force to pull the mop up and down, which is more laborious and inconvenient to operate. Utility Model Content

[0004] The utility model aims at the above problems existing in the prior art and proposes a water squeezing structure for a cleaning head of a collodion mop. The technical problem solved by the utility model is that the cleaning head of a collodion mop can be squeezed dry and the operation is more labor-saving.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A water squeezing structure for a cotton mop cleaning head comprises a water squeezing bin, in which a movable seat capable of moving up and down is arranged, and the character is that a water squeezing rod is arranged on the movable seat, and the water squeezing rod is arranged along the transverse direction or the longitudinal direction of the movable seat, and guide grooves are obliquely arranged on the inner walls opposite to the two ends of the water squeezing bin and the water squeezing rod, and the two ends of the water squeezing rod respectively extend into the corresponding guide grooves, and when the movable seat moves up and down, the water squeezing rod can move back and forth along the longitudinal direction or the transverse direction of the movable seat under the guidance of the guide grooves, and a spring is arranged between the movable seat and the water squeezing bin to provide resistance when the movable seat moves downward.

When in use, the cleaning head of the rubber cotton mop is placed on the moving seat and pressed downward with force. The spring provides resistance, so that the cleaning head of the rubber cotton mop is in a compressed state. At the same time, the moving seat moves downward, and the squeezing rod on the moving seat moves horizontally under the guidance of the guide groove. The cleaning head of the rubber cotton mop is pressed against the squeezing rod. The movement of the squeezing rod squeezes the water inside the cleaning head of the rubber cotton mop from one side to the other. When the water in the cleaning head of the rubber cotton mop on the squeezed side exceeds the water absorption saturation, the water is squeezed out, thereby realizing the squeezing of water from the cleaning head of the rubber cotton mop. When the squeezing rod is arranged along the transverse direction of the moving seat, the guide groove can The water squeezing rod is guided to move back and forth along the longitudinal direction of the moving seat, and when the water squeezing rod is arranged along the longitudinal direction of the moving seat, the guiding groove can guide the water squeezing rod to move back and forth along the transverse direction of the moving seat; the water squeezing rod can move up and down with the moving seat and move back and forth along the transverse direction or the longitudinal direction of the moving seat under the limitation of the guiding groove, and can squeeze out water on the rubber cotton mop cleaning head when the rubber cotton mop cleaning head presses the moving seat downward, which is convenient and labor-saving to operate, and the spring provides a reaction to the pressed rubber cotton mop cleaning head, so that the water squeezing rod can move relative to the rubber cotton mop cleaning head when it is embedded in the rubber cotton mop cleaning head, so that the rubber cotton mop cleaning head can be squeezed dry to the utmost extent, thereby improving the water squeezing effect.
