Description

Technical Field

[0001] The utility model relates to the technical field of mop cleaning, in particular to a flat mop cover and a cleaning tool. Background Art

[0002] The flat mops on the market squeeze out water and remove dirt by pulling the stroking head up and down. The specific principle is: when the user pulls the stroking head, the scraper arranged in the stroking mouth moves up and down relative to the flat mop head, and under certain circumstances, they are squeezed against each other, thereby squeezing water from the flat mop head. For example, the utility model with application number 202120271627.6 is named as a patent for a hands-free mop. The stroking head structure of the self-squeezing horizontal flat mop includes a stroking head body and a water squeezer arranged in the stroking head body. The patent includes a mop rod and a mop plate movably connected to the bottom end of the mop rod, and the mop plate can move relative to the mop rod to a relative position. The mop board has a parallel water squeezing state and a relatively inclined mopping state, a wiping object is arranged on the surface of the mop board, a sleeve is arranged on the mop rod which can move up and down relative to the mop rod, the sleeve is connected to the mop rod through a connecting part, a limiting structure is arranged between the mop rod and the sleeve to prevent the circumferential movement between the mop rod and the sleeve, the sleeve is provided with a through hole for the mop board to pass through, the sleeve comprises a first part and a second part, the first part and the second part are fixedly connected, and a scraping edge for squeezing the wiping object is integrally formed on one side of the through hole on the second part, which solves the problems of unreasonable structure, unsmooth use and complicated manufacturing and assembly of the flat mop.

[0003] However, the following problems still exist: 1. The scraping edge will produce certain wear after long-term use, which affects the cleaning effect of the mop head. Moreover, the scraping edge is integrally formed with the mop head and cannot be replaced after damage, which affects user use; 2. The scraping edge cannot swing up and down with the mop head. When scraping the mop head that has been cleaned, the mop head needs to be reciprocated up and down in the water squeezing area socket. When moving downward, it is affected by gravity and does not require the user to spend a lot of effort, but when moving upward, it takes a lot of effort to lift the mop head; 3. When cleaning and scraping the mop head, different floor materials require different humidity of the mop head, but in the prior art, the distance between the scraping edge and the mop head is fixed, which cannot meet the different requirements of wooden floors and floor tiles. A mop board with high humidity may damage the wooden floor after long-term use, and a mop board with low humidity may not clean the floor tiles thoroughly, affecting use. Utility Model Content
