Swimming Pool Cleaning Robot with Waterline Cleaning Function

This application claims priority to Chinese Patent Application No. 202420751663.6, filed on Apr. 12, 2024, which is hereby incorporated by reference in its entirety.

The present disclosure relates to a cleaning robot, particularly to a swimming pool cleaning robot with a waterline cleaning function.

With the rapid development of automation technology, water surface-cleaning robots are playing an increasingly important role in the maintenance and cleaning of public and private swimming pools, reservoirs, and other venues. Traditional water surface-cleaning robots are primarily designed to address the issue of cleaning floating debris on the water surface. Their basic working principle involves using internal or external driving devices to propel the robot across the water surface, where roller brushes, suction mechanisms, or other devices located at the bottom or front of the robot collect floating debris into a debris collection box. While these robots are highly effective in removing floating debris from the water surface, they still have certain limitations in terms of the comprehensiveness and thoroughness of pool cleaning.

Especially concerning the issue of waterline stains along the edges of pools and adjacent walls, these stains are formed due to prolonged contact and soaking of water against the walls. They not only detract from the aesthetic appeal of the pool but can also gradually harden over time without timely cleaning, forming stubborn stains that are difficult to remove. Currently, the water surface-cleaning robots on the market do not provide effective cleaning solutions for waterline stains, and cleaning these stains typically requires manual labor, which is not only time-consuming and labor-intensive but also particularly arduous for large or commercial pools.

Moreover, since the existing water surface-cleaning robot mainly realizes cleaning work by floating on water, when faced with tasks that require cleaning close to the edges of the pool, such as waterlines, they lack sufficient counter thrust to counteract the influence of water currents and can easily deviate from the cleaning area, leading to unsatisfactory cleaning results. The existence of this problem further exacerbates the difficulty of cleaning waterline stains.

In summary, although advancements have been made in the current water surface-cleaning robot technology in some aspects, there is still significant room for improvement in areas such as waterline stain cleaning, water quality monitoring, and energy self-sufficiency. Therefore, there is an urgent need for a new type of pool cleaning robot that can comprehensively enhance pool cleaning efficiency and effectiveness while achieving intelligent and automated cleaning and maintenance.

In order to solve the above problems, the present disclosure provides a swimming pool cleaning robot with a waterline cleaning function, which can effectively solve many shortcomings in the prior art.

The present disclosure is implemented by the following technical solution: a swimming pool cleaning robot with a waterline cleaning function includes:

Preferably, the waterline cleaning device includes a waterline roller brush and a waterline propeller, the waterline roller brush is arranged at the side of the apparatus main body, the waterline roller brush is used for making contact with a wall to clean the waterline; and

All of the features disclosed in this specification, or the steps of all methods or processes disclosed, may be combined in any manner, except those features and/or steps that are mutually exclusive.

Any feature disclosed in this specification (including any accompanying claims, abstract and drawings) may be replaced by other equivalent or alternative features serving a similar purpose, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only one example of a generic series of equivalent or similar features.

As shown in, a swimming pool cleaning robot with a waterline cleaning function of the present disclosure includes an apparatus main bodyserving as a structural foundation of a water surface cleaning robot, wherein a control mainboard, a power supply, and a driving system are built in the apparatus main body;

Wherein, as shown in, the waterline cleaning device includes a waterline roller brushand a waterline propeller, the waterline roller brushis arranged at the side of the apparatus main body, the waterline roller brushis used for making contact with a wall to clean the waterline. During the waterline cleaning process, the waterline propelleris opened to apply a tail thrust, ensuring that the waterline roller brushremains in constant contact with the waterline position on the pool surface to achieve the purpose of cleaning the waterline. In this embodiment, the waterline roller brush is made of soft rubber and has a circular shape. The brush is composed of flakes and dots, and performs circular rolling to scrub and clean the wall surface; and

As shown in, the debris collection device includes a main roller brushand a debris collection box, the debris collection boxis installed at the bottom of the apparatus main body, with one side open to form a debris inlet, the main roller brushis installed on one side of the debris inlet, the main roller brushis controlled to rotate by a driving system, debris on the water surface is collected into the debris collection boxby the main roller brush, and the debris collection boxis provided with small holes for water inflow and outflow. The small holes for water inflow and outflow help maintain balance inside the debris collection box. During cleaning, the main roller brushrotates to collect the floating debris on the water surface into the debris collection box, the debris passes through the debris inlet and is collected inside the debris collection box, making the process simple and convenient.

In order to equip the entire robot with the ability to move forward, in the present embodiment, there is also included a thrust system, wherein the thrust system includes a plurality of self-powered main motion propellersinstalled on a tail end of the apparatus main body, the thrust system is controlled by the control mainboard and powered by the power supply, and the apparatus main bodyis propelled forward by the thrust system.
