Description

Technical Field

[0001] This utility model relates to the field of intelligent cleaning equipment technology, especially swimming pool cleaning technology, and more specifically, to a garbage collection device and a dual-roller brush swimming pool robot. Background Technology

[0002] Against the backdrop of booming technological innovation and high-end manufacturing, the robotics industry has undoubtedly become a global focus. Many major economies are committed to maintaining and enhancing their manufacturing competitiveness through development in this field. Particularly in the smart home sector, robots are increasingly integrated into daily life, with various types gradually replacing human labor to perform complex household chores.

[0003] In the specific field of pool cleaning technology, the dual-roller brush pool robot, as a professional cleaning device, is becoming increasingly important. These robots are specifically designed for cleaning private or public pools, significantly reducing labor costs and providing a more thorough and efficient cleaning experience compared to traditional manual methods. With continuous technological advancements and decreasing costs, using dual-roller brush pool robots for pool cleaning is gradually becoming a trend.

[0004] In existing dual-roller brush pool cleaning robots, after finishing their work, the robot typically remains at the last cleaning position, waiting for the user to retrieve it. Therefore, dual-roller brush pool cleaning robots must be sold with a long pole for users to use for retrieval. This process is complex, cumbersome, and inconvenient. Furthermore, using a pole can easily scratch the robot, and the retrieval process can also cause debris inside the robot to fall out, resulting in a very unsatisfactory effect. In addition, ordinary pool cleaning equipment has a rather monotonous color scheme and lacks aesthetic appeal.

[0005] For example, Chinese invention patent CN118933412A, published on November 12, 2024, includes a pool cleaning robot body and a first controller, a first wireless communication module, and a water quality detection module disposed within the pool cleaning robot body. The first controller is connected to the first wireless communication module and the water quality detection module respectively. The water quality detection module is used to detect water quality data, which is received by the first controller and transmitted via radio signals through the first wireless communication module to wirelessly transmit the water quality data to an external device. Its main purpose is to transmit the water quality information detected in the underwater dual-brush pool robot to a wireless communication device on land (the second wireless communication module 23, the second controller 22, etc., referred to in the text and figures). The communication method involves direct transmission from the underwater surface (or the deepest part of the pool) to a wireless communication device on land. As is well known, underwater wireless signal transmission is much slower than airborne transmission, easily causing propagation delays, especially noticeable in long-distance communication. Underwater wireless signal transmission is also easily affected by factors such as water temperature, salinity, turbidity, and pressure. Furthermore, water is a good conductor, limiting the penetration depth of signals during transmission, making data or signal loss easy. Therefore, in practical operation, this solution is not very effective, especially when the dual-roller brush pool robot moves to a corner or is obstructed by other objects, causing frequent signal interruptions and affecting cleaning and communication performance.

[0006] Therefore, ensuring stable signal transmission and ease of use when the dual-brush pool robot achieves wireless communication with the shore are technical problems that the industry urgently needs to solve. Utility Model Content

Detailed Implementation

[0031] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Example 1

[0032] like Figures 1-7As shown, this embodiment provides a dual-roller brush swimming pool robot, including a body, which is the shell of the swimming pool robot. The body has an inner cavity, and a walking mechanism is provided on the lower or side part of the body. The walking mechanism is a walking wheel or a walking track, which is driven by a drive motor to move forward, backward, and turn, which is the same as the walking method of existing swimming pool robots. In this embodiment, the transmission structure of the walking mechanism will not be described in detail.

[0033] The waste collection device is located within the inner cavity of the main body. A collection port is located at the bottom of the waste collection device, and a filter screen is located on the side and / or top. This waste collection device, as described in this embodiment, is also known as a "trash can" or "trash bin" in existing pool robots. Its principle is that water from the pool enters through the collection port and then flows out through the filter screen to the drain. Trash or coarse particles mixed in the water are blocked by the filter screen and remain inside the waste collection device, thus achieving the effect of collecting waste.

[0034] A drain outlet is provided at the top and / or side of the main body, and the drain outlet communicates with the inner cavity. Because a waste collection device is provided in the inner cavity, the drain outlet also communicates with the waste collection device.

[0035] The water inlet is connected to the collection port and is located at the bottom, front, or side of the main body. In specific implementations, the water inlet and the collection port may overlap or share a single inlet.

[0036] A roller brush, comprising a roller brush shaft and roller brush blades disposed on the outer periphery of the roller brush shaft, is located at the front or lower part of the main body. The roller brush is driven to rotate by a drive motor or by a traveling mechanism. In this embodiment, the drive motor first drives the traveling mechanism to rotate, and then the traveling mechanism drives the roller brush to rotate. The roller brush blades are used for collecting garbage, and can also scrape the bottom wall, side wall, and water level of the pool, making garbage collection easier and cleaning more thorough.

[0037] The auxiliary brush is located at the water inlet, and the roller brush and the auxiliary brush are respectively located on two sides of the water inlet, and the roller brush and the auxiliary brush are arranged parallel to each other; during operation, the auxiliary brush and the roller brush rotate in opposite directions.

[0038] In one embodiment, the auxiliary brush includes a base and a brush body. The base is fixedly connected to the main body or integrally formed. The brush body is rotatably disposed in the base. The brush body includes a rotating shaft and a plurality of rows of scraping blades disposed on the rotating shaft. The base is provided with concave teeth, which correspond to the scraping blades. When the brush body rotates, the scraping blades move within the concave teeth.

[0039] In one embodiment, the scraper blade and the roller brush blade at least partially overlap. When partially overlapping, the roller brush blade, when rotating, can drive the scraper blade to move a certain distance, thereby driving the auxiliary brush to rotate.

[0040] In one embodiment, one side of the substrate has a working surface, the working surface is fan-shaped, and the working surface is one of the sides of the water inlet, and the concave teeth are disposed on the working surface.

[0041] In one embodiment, the central angle of the sector is 170° ≤ 110°. Preferably, it is 160°, which allows water and waste to enter more effectively.

[0042] In one embodiment, the fan-shaped working surface has an upper working surface and a lower working surface. When the concave teeth are positioned on the working surface, they have upper and lower concave teeth. When the scraper blades rotate, two rows of scraper blades are simultaneously positioned at the upper and lower concave teeth on both the upper and lower working surfaces. When both rows of scraper blades are simultaneously positioned at the upper and lower concave teeth on both the upper and lower working surfaces, the scraper blades precisely block the concave teeth positions on the upper and lower working surfaces, forming a unified plane, which facilitates the passage of water.

[0043] In one embodiment, a secondary brush gear is provided at one end of the rotating shaft, and a shaft gear is provided on the traveling mechanism. The secondary brush gear meshes with the shaft gear. As described above, the traveling mechanism is driven by a drive motor. Therefore, while the drive motor drives the traveling mechanism, the shaft gear drives the secondary brush gear to rotate, thereby driving the secondary brush to rotate.

[0044] At this time, during rotation, the scraper blades on the secondary brush and the roller brush may not contact each other, or a gap may form. This can still achieve the effect of garbage collection.

[0045] In one embodiment, the lower part of the base is provided with a perforation; or, the lower part of the base is provided with a through hole; or, the lower part of the base is provided with a drainage groove. The perforation, through hole, or drainage groove mainly serve to allow water, particles, etc., inside the pool robot to be discharged directly from the perforation, through hole, or drainage groove when the robot is lifted.

[0046] In one embodiment, the auxiliary brush has at least two sections, at least one of which is rotated by a walking mechanism.

[0047] In this embodiment, the scraper blades on the secondary brush can also be set in a trapezoidal or wedge shape, which can achieve the effect of garbage collection, and reduce the impact of water flow because its working surface is narrowed.

[0048] In this embodiment, the scraper blades on the secondary brush are arranged according to concave teeth, which are arranged in a row on the base. Therefore, the scraper blades also need to be arranged in rows. In this embodiment, at least one row of scraper blades can achieve the desired effect, but a single row of scraper blades only works once per revolution, greatly reducing efficiency. Therefore, 6-12 rows of scraper blades can be used. When there are more than 12 rows of scraper blades, the blades are too densely arranged, making it difficult to pick up stones or large leaves, branches, etc., thus reducing the effect. The figure in this embodiment shows 12 rows of scraper blades.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the technical solution of this utility model, and are not intended to limit the specific implementation of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of this utility model should be included within the protection scope of the claims of this utility model.
