The window cleaner in this embodiment has two scraper strips of different hardness, the harder scraper strip can remove stubborn stains, and the softer scraper strip can remove liquids, and the combination of the two scraper strips is conducive to removing different stains, and the decontamination effect is better than that of a single scraper strip.
[0023] As a preferred embodiment, the first scraper 2 and the second scraper 3 are movably connected to the housing 1 respectively, and the first scraper 2 and the second scraper 3 can move in the direction of approaching and moving away from wiping the glass respectively; it also includes a control mechanism for selecting to use the first scraper 2 or the second scraper 3 to clean the glass, the control mechanism includes an operating member 4, the operating member 4 is slidably connected to the housing 1, and the operating member 4 includes a push rod 41, the first scraper 2 has a first slide groove 20, and the first slide groove 20 is inclined from top to bottom; the first The second scraper 3 has a second slide groove 30, and the second slide groove 30 is inclined from top to bottom. The first slide groove 20 is inclined in the opposite direction to the second slide groove 30. In this embodiment, the first slide groove 20 and the second slide groove 30 overlap in some areas, and the push rod 41 is simultaneously arranged in the first slide groove 20 and the second slide groove 30; the sliding operation member 4, the push rod 41 pushes the first scraper 2 close to the glass direction, and the second scraper 3 moves away from the glass direction, or the push rod 41 pushes the first scraper 2 away from the glass direction, and the second scraper 3 moves close to the glass direction. When wiping windows daily, stubborn stains (such as mortar, bird droppings, etc.) are usually removed first. At this time, a harder scraper is more suitable. After removing the stubborn stains, a softer scraper is selected to remove the water. In this embodiment, the first scraper 2 and the second scraper 3 in this embodiment are integrated on a window cleaning device. By controlling the operation member 4, the first scraper 2 and the second scraper 3 can be used selectively. The problem of large resistance when using at the same time but general effect is solved. The number of the first slide groove 20, the second slide groove 30, and the push rod 41 is 2, 3, or 4 respectively. A number of more than 2 can achieve more stable operation.
