Description

Technical Field

[0001] The utility model relates to a water scraping device of a floor washing robot, in particular to a water scraping device and a floor washing robot, belonging to the technical field of floor washing robot equipment. Background Technique

[0002] A floor washing robot, that is, a household intelligent cleaning robot, is a kind of intelligent home service robot. It can automatically complete the cleaning work of the ground, windows, etc. by virtue of certain artificial intelligence, including a sweeping robot, a window cleaning robot, etc. It is mainly to reduce the manual cleaning work and bring convenience to family life.

[0003] After the existing floor washing robot is used for a long time, the outer diameter of the roller becomes smaller (mainly due to the change of the outer diameter of the roller cloth), resulting in insufficient interference or a gap between the fixed water scraping strip and the roller cloth. As a result, the water in the roller cloth cannot be scraped off by the water scraping strip, leading to more water stains on the ground, and the hair cannot be scraped off either, and the hair is wound around the roller, bringing potential safety hazards to the use of the floor washing robot and the risk of needing maintenance. Summary of the Invention

[0024] The following describes the preferred embodiments of the utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the utility model, and are not used to limit the utility model.

[0025] Embodiment 1

[0026] As Figure 1 shown, this embodiment provides a wiper device, which includes a pressing mechanism 1, a wiper strip 2 and a water spraying plate 6. Among them, the pressing mechanism 1 is connected to or abuts against the wiper strip 2; the wiper strip 2 is in interference fit with the roller cloth 7 on the roller 8; the pressing mechanism 1 includes a torsion spring or a compression spring, and both the pressing mechanism 1 and the wiper strip 2 are installed on the floor washing robot.

[0027] In this embodiment, the pressing mechanism 1 is a torsion spring. Herein, the pressing mechanism 1 is connected to the wiper strip bracket 5 through the pressing mechanism mounting member 4;

[0028] A wiper strip support column 3 for supporting the wiper strip 2 is arranged in the wiper strip bracket 5. The water spraying plate 6 is connected to the wiper strip bracket 5.

[0029] Specifically, when the roller rotates, the roller cloth 7 is in floating fit with the wiper strip. The wiper strip 2 is always in close fit with the rotating roller 8 under the pressure of the pressing mechanism 1 (torsion spring), so as to ensure that even when the outer diameter of the roller becomes smaller after long-term use, it can still be in close fit with the roller cloth, ensuring the cleaning effect. In addition, the horizontally placed wiper strip can match a larger dirt suction port, and the horizontal wiper strip can act on the roller rotating clockwise or the roller rotating counterclockwise.

[0030] Embodiment 2

[0031] As Figure 2 shown, this embodiment provides a wiper device. The difference from Embodiment 1 is that the pressing mechanism 1 is a compression spring. Herein, the end of the pressing mechanism 1 abuts against the wiper strip 2; the water spraying plate 6 is installed on the housing to which the pressing mechanism 1 is connected.

[0032] Specifically, the housing of this embodiment is connected with a dirt suction channel 01. Herein, a second wiper strip 02 is installed at the end of the dirt suction channel 01.

[0033] Specifically, in this embodiment, the metal wiper strip 2 is provided with three rivet posts for cooperation with the upper part of the main housing of the dirt suction channel (housing), and a compression spring is arranged in the middle to elastically move the wiper strip. Two columns are arranged above the main housing of the dirt suction channel for sliding guiding and limiting cooperation with the wiper strip.

[0034] The metal wiper strip is always pushed forward by the compression spring until it reaches the preset maximum limit value. The new roller flannelette has a large density and a large outer diameter of the flannelette. When it cooperates with the wiper strip 2, it will squeeze the wiper strip to retreat until it reaches the preset value of the compression spring. Thus, excessive current will not be generated during the rotation of the roller brush, and it is also in close fit with the roller. When the roller is used for a long time, the density of the flannelette will decrease and the outer diameter of the flannelette will become smaller. At this time, the elastic wiper strip will move forward and fit tightly with the roller cloth again. It can not only ensure the cleaning effect of new and old rollers, but also effectively prevent hair entanglement, and fit tightly with the roller. When the hair is taken away by the roller and rotates to the wiper strip, it is squeezed by the wiper strip and then sucked into the dirt suction channel.

[0035] Embodiment 3

[0036] This embodiment provides a floor washing robot, which has the wiper device in Embodiments 1-2. The wiper device is connected to the floor washing robot through the wiper strip bracket 5 or the housing.

[0037] Through the arrangement of the pressing mechanism, the wiper device of the present utility model can continuously press the wiper strip against the drum cloth, enabling effective water scraping. Moreover, it avoids the problem that hair cannot be scraped off, as well as potential safety hazards and maintenance risks.

[0038] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and without departing from the spirit and scope of the present utility model, various changes and improvements will occur to the present utility model, and all these changes and improvements fall within the scope of protection required by the present utility model. The scope of protection required by the present utility model is defined by the appended claims and their equivalents.
