TECHNICAL FIELD

[0001] The present application belongs to the technical field of mop cleaning, and relates to a water-saving mop cleaning device. BACKGROUND

[0002] In order to facilitate the cleaning of the flat mop, Chinese Invention Patent Application 201711119340.6 discloses a kind of extrusion flat mop cleaning tool. Including mop bucket and flat mop, flat mop includes mop rod and hard flat mop head movably connected to mop rod, mop head is provided with wiping material;Mop bucket is provided with extrusion frame, opening is formed in extrusion frame, extrusion frame on one side of opening is provided with extrusion device, extrusion device and the other side of opening form extrusion opening;Mop bucket includes extrusion area and water area located at different positions, extrusion frame is located above extrusion area, the extrusion frame or extrusion device has water outlet channel for guiding water extruded from wiping material;Extrusion device is movably connected to extrusion frame, wiping material drives extrusion device to move to narrow position when flat mop head is pressed down, so that extrusion opening is smaller;When flat mop head is pulled up, wiping material drives extrusion device to move away from the narrow position, so that the extrusion opening becomes larger.

[0003] The above-mentioned patent designs extrusion area and water area in the mop bucket, and the extrusion frame or extrusion device has a water outlet channel for guiding water extruded from the wiping material. Therefore, when cleaning and squeezing the wiping material on the flat mop head, the cleaning operation and the squeezing operation can be completed in the same area, i.e. the extrusion area: when cleaning, there is water in the extrusion area, then through the reciprocating movement of the flat mop, the water on the wiping material is extruded and flows to the water area, the wiping material is dehydrated after extruding water, and the above process is repeated to transfer most of the water in the extrusion area to the water area. In this process, the cleaning operation and the squeezing operation are completed at the same time. When in use, in order to save water, the dirty water on the wiping material will flow back to the water area, which will affect the cleanliness of subsequent cleaning, and the water in the water area needs to be replaced after several times of use, causing water waste.

[0004] In order to further save water, Chinese Invention Patent Application 201810621367.3 discloses a kind of flat mop cleaning tool, including mop and mop bucket cooperating with the mop, the mop includes mop rod;Mop head;Wiping material;The mop bucket includes bucket body;Extrusion opening, for mop head insertion;Extrusion member, for extruding mop head after mop head is inserted into extrusion opening;Extrusion cavity, provided in the bucket body, mop head can move up and down in the extrusion cavity;Water spraying device, for driving water in the extrusion cavity to spray on the wiping material during the movement of the mop from high position to low position.

[0005] Because the mop is in vertical state when spraying water, the water sprayed on the mop flows downward, in order to make the cleaning water evenly distributed on the mop head wiping object, the spraying time on the upper end of the mop head wiping object is greater than that on the lower end. The water spraying device in the above patent sprays on the mop head wiping object in real time and equally with the movement of the mop, which inevitably causes the cleaning water to be unevenly distributed on the mop head wiping object.
