When the machine is pushed, the wiper will bend in the opposite direction of movement to push the liquid; when the vacuum cleaner is pulled back, the wiper will also bend in the opposite direction of movement. The liquid on the surface to be cleaned at the rear of the machine cannot enter the front end of the suction port of the vacuum cleaner, resulting in a poor cleaning effect on the surface to be cleaned and a poor user experience.
基于现有技术存在的缺点，急需研究一种吸尘器刮水条及吸尘器，来解决上述问题。Based on the shortcomings of the prior art, there is an urgent need to develop a wiper strip for a vacuum cleaner and a vacuum cleaner to solve the above-mentioned problems.

所述支撑脚3的第二端面与所述刮水板2的一端位于同一平面内，且所述刮水板2与所述第二端面之间的夹角小于90°；The second end surface of the supporting foot 3 and one end of the wiper blade 2 are located in the same plane, and the included angle between the wiper blade 2 and the second end surface is less than 90°;
所述刮水板2通过所述连接件1与所述吸尘器的吸嘴连接，以使液体能够沿着所述刮水板2进入所述吸尘器的吸嘴。The wiper board 2 is connected to the suction nozzle of the vacuum cleaner through the connecting member 1 so that liquid can enter the suction nozzle of the vacuum cleaner along the wiper board 2.
需要说明的是：现有吸尘器产品中的刮水条多数是垂直放置，当吸尘器推动时刮水条会向运动相反方向弯折从而将液体推动；当吸尘器向后拉动时刮水条同样向运动相反方向弯折导致机器后端地面的液体无法进到吸尘器吸嘴前端，导致地面清洁效果较差。而本实施例的吸尘器刮水条保证吸尘器在前推时能将地面液体完整推动，且不会在吸尘器刮水条后端有液体遗留；当吸尘器向后拉动时能保证在吸尘器刮水条后端地面的液体由于所述支撑脚3的支撑，液体能够到达吸尘器刮水条的前端。由吸尘器的推拉动作将地面液体集中至吸尘器吸嘴前面，从而保证吸尘器的清洁效果。It should be noted that most of the wiper strips in existing vacuum cleaner products are placed vertically. When the vacuum cleaner is pushed, the wiper strip will bend in the opposite direction of the movement to push the liquid; when the vacuum cleaner is pulled back, the wiper strip will also move in the same direction. Bending in the opposite direction causes the liquid on the ground at the rear of the machine to not enter the front of the suction nozzle of the vacuum cleaner, resulting in poor floor cleaning. The wiper strip of the vacuum cleaner of this embodiment ensures that the vacuum cleaner can completely push the liquid on the ground when it is pushed forward, and there will be no liquid left behind at the rear end of the wiper strip of the vacuum cleaner; when the vacuum cleaner is pulled back, it can ensure that it is behind the wiper strip of the vacuum cleaner. Due to the support of the supporting feet 3, the liquid on the ground can reach the front end of the wiper strip of the vacuum cleaner. The push-pull action of the vacuum cleaner concentrates the floor liquid to the front of the suction nozzle of the vacuum cleaner, thereby ensuring the cleaning effect of the vacuum cleaner.
具体地，当吸尘器前推时由于所述支撑脚3的支点作用，会使刮水板2的前端下压到地面，从而保证地面液体在吸嘴前端集中。Specifically, when the vacuum cleaner is pushed forward, due to the fulcrum action of the supporting foot 3, the front end of the wiper 2 is pressed down to the ground, so as to ensure that the ground liquid is concentrated at the front end of the suction nozzle.
当吸尘器后拉时由于支撑脚3的支撑作用，会使刮水板2的前端翘起，从而使所述刮水板2与地面形成空隙，所述吸尘器的后端地面液体通过空隙到达所述吸尘器的吸嘴前端；重复推拉所述吸尘器使液体都集中至吸嘴的前端提高吸尘器的清洁效果。When the vacuum cleaner is pulled back, due to the supporting effect of the supporting feet 3, the front end of the wiper 2 will be tilted, so that the wiper 2 forms a gap with the ground, and the ground liquid at the rear end of the vacuum cleaner reaches the The front end of the suction nozzle of the vacuum cleaner; repeatedly pushing and pulling the vacuum cleaner to concentrate the liquid on the front end of the suction nozzle to improve the cleaning effect of the vacuum cleaner.
