Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Further, in the exemplary embodiments, since the same reference numerals denote the same components having the same structure or the same steps of the same method, if an embodiment is exemplarily described, only a structure or a method different from the already described embodiment is described in other exemplary embodiments.

Throughout the specification and claims, when one element is described as being "connected" to another element, the one element may be "directly connected" to the other element or "electrically connected" to the other element through a third element. Furthermore, unless explicitly described to the contrary, the term "comprising" and its corresponding terms should only be taken as including the stated features, but should not be taken as excluding any other features.

The floor mopping robot is intelligent household equipment capable of realizing automatic floor mopping, and the floor mopping robot can automatically mop the floor by setting floor mopping parameters (including the humidity of cleaning cloth, the floor mopping force, the floor mopping times and the like). The mopping robot is usually driven by a motor, and therefore, is further provided with a charger or a charging seat, and when the mopping robot finishes mopping or the power is insufficient during mopping, the mopping robot needs to be controlled to return to the charger or the charging seat for replenishing power. If the floor cleaning robot needs to return to the charging process during the floor cleaning process or needs to enter another area after cleaning of one area is completed, the floor cleaning robot is likely to pass through a clean area which is already cleaned again, and the cleaning cloth of the floor cleaning robot is usually not clean. If the cleaning cloth is directly left to wipe the clean area again, the cleaning cloth is likely to pollute the clean area for a second time due to the unclean cleaning cloth. In order to solve the problem, the application provides a mopping robot, when mopping the robot through clean region, utilize tray elevating system to rise the tray to avoid dirty rag and clean regional contact, thereby avoided clean regional secondary pollution, improved clean effect and efficiency.

As shown in fig. 1 and 2, the floor mopping robot includes: a tray mechanism 1, a rotating mechanism 3 and a tray lifting mechanism 10; the rotating mechanism 3 is connected with the tray mechanism 1 and used for driving the tray mechanism 1 to rotate, and the tray lifting mechanism 10 is arranged between the rotating mechanism 3 and the tray mechanism 1 and used for lifting or lowering the tray mechanism 1. Specifically, tray elevating system includes: the first end of the top transmission shaft is in transmission connection with a rotating mechanism which drives the tray mechanism to rotate along the rotating direction of the tray mechanism, the first end of the middle transmission shaft is in transmission connection with the second end of the top transmission shaft along the rotating direction of the tray mechanism, the first end of the bottom transmission shaft is in transmission connection with the second end of the middle transmission shaft along the rotating direction of the tray mechanism, and the second end of the bottom transmission shaft is in transmission connection with the tray mechanism along the rotating direction of the tray mechanism. The driving force of the rotating mechanism 3 is transmitted to the tray mechanism 1 through the three transmission shafts, so that the normal cleaning operation of the tray mechanism 1 is realized, and meanwhile, the lifting motion of the tray mechanism 1 is realized by utilizing the mutual motion of the three transmission shafts in the vertical direction.
