It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Fig. 1 is a schematic structural diagram of an ash scraping assembly according to an embodiment of the present invention, as shown in fig. 1.

The utility model discloses an in the embodiment, provide a scrape grey subassembly, include: the connecting bracket 10, the soft glue connecting piece 20, the scraping strip 30 and the floating bracket 40.

The floating bracket 40 has a pivot end 41 and an adjusting end 42 which are oppositely arranged, the pivot end 41 is pivoted on the connecting bracket 10, and the adjusting end 42 floats up and down on the rotating shaft of the pivot end 41. One end of the soft rubber connecting piece 20 is connected with the connecting support 10, the other end of the soft rubber connecting piece is connected with the adjusting end 42, and the soft rubber connecting piece 20 seals a gap between the connecting support 10 and the adjusting end 42. One end of the scraping strip 30 is connected with the adjusting end 42, and the other end is configured to be tightly attached to a cleaning surface, and the adjusting end 42 moves relative to the moving direction of the soft rubber connecting piece 20 under the action of external force on the scraping strip 30.

The embodiment of the utility model provides a technical scheme, the both ends of flexible glue connecting piece 20 are connected with linking bridge 10 and floating support 40 respectively, scrape the strip 30 and are connected with floating support 40. The flexible glue connecting piece 20 has elasticity, and when the scraping bar 30 meets an obstacle, the flexible glue connecting piece 20 can generate elastic deformation to drive the scraping bar 30 to float and cross the obstacle by the adjusting end 42 of the floating support 40, so that the friction between the scraping bar 30 and the ground can be automatically adjusted, the abrasion is reduced, and the service life is prolonged. Meanwhile, the sound of friction between the wiper strip 30 and the ground is reduced, and the jitter frequency is effectively reduced. In addition, the soft glue connecting piece 20 seals the gap between the adjusting end 42 of the floating support 40 and the connecting support 10, so that the problem of shaking of the device when an obstacle is met and the problem of the gap easily generated when the floating support 40 floats can be solved, and the cleaning efficiency is improved.

For example, during normal operation, the scraping strip 30 can contact the ground by its own weight and the elastic property of the flexible glue connecting member 20, so as to fit the ground well, thereby gathering the garbage on the ground.

When the scraping strip 30 is jacked up under the action of external force, the scraping strip 30 drives the adjusting end 42 to extrude the soft rubber connecting piece 20, and the soft rubber connecting piece 20 is compressed to generate elastic deformation. For example, when an obstacle is encountered, the wiper strip 30 is lifted by the obstacle when crossing the obstacle, and the wiper strip 30 drives the adjusting end 42 of the floating bracket 40 to float. In the upward floating process of the scraping bar 30, the adjusting end 42 extrudes the soft rubber connecting piece 20, and the soft rubber connecting piece 20 is compressed to generate elastic deformation.

When the external force applied to the wiper strip 30 is removed, the wiper strip 30 is restored to contact with the cleaning surface, and the elastic deformation generated by the soft rubber connecting piece 20 is removed. For example, after the scraping bar 30 passes over the obstacle, when the obstacle is eliminated, the elastic deformation generated by the soft rubber connecting piece 20 is released, the adjusting end 42 drives the scraping bar 30 to contact with the ground by the self gravity and the elastic characteristic of the soft rubber connecting piece 20, and the scraping bar 30 moves back to the normal movement state.

In the process that the scraping strip 30 floats up and down, the soft rubber connecting piece 20 always seals the gap between the adjusting end 42 and the connecting support 10, so that garbage is prevented from passing through the gap, and the cleaning efficiency is improved.
