Description

Technical Field

[0001] This utility model relates to the field of robotics, specifically to a pool cleaning robot for cleaning the inside of a pool. Background Technology

[0002] Currently, underwater robots have evolved into a power-cable era, but battery life is limited. There is a need to improve battery life, reduce power consumption, and enhance obstacle-crossing and escape capabilities. However, existing robots prioritize improving obstacle-crossing and escape capabilities and their ability to clean debris in a contradictory way. In current technology, cleaning robots for swimming pools typically have a suction port at the bottom. This port is used to clean the surface of the pool bottom and / or pool walls, drawing in water along with impurities and particles for filtration to achieve the cleaning purpose.

[0003] In the aforementioned existing technologies, the bottom suction port is typically flush with the robot's bottom surface. To maintain a certain obstacle-crossing ability, the robot's bottom surface is at a certain height from the surface to be cleaned, resulting in a certain distance between the suction port and the surface. If this distance is too large, the suction force of the suction port on the surface to be cleaned will weaken, reducing its ability to remove dirt; if the distance is too small, the robot's obstacle-crossing and escape abilities will be weakened, and it will be blocked by obstacles that are too large. Utility Model Content

[0004] To address the technical problem, the purpose of this utility model is to provide a pool cleaning robot that can ensure both suction power and obstacle-crossing and escape capabilities. The specific technical solution adopted is as follows:

[0005] A pool cleaning robot includes: a shell; a chassis; a suction port on the chassis; an extension structure disposed on the chassis and surrounding the suction port, the extension structure being made of a flexible material, the distance between the extension structure and the walking surface of the pool cleaning robot being less than the distance between the suction port and the walking surface; and a suction channel disposed within the shell, wherein the suction channel communicates with the suction port and the extension structure.

[0006] Furthermore, the aforementioned pool cleaning robot has an anti-clogging structure in its extended structure.

[0007] Furthermore, in the aforementioned pool cleaning robot, the anti-clogging structure is an inclined plane that extends towards the front end of the pool cleaning robot; the inclined plane is made of a flexible material.

[0008] Furthermore, in the aforementioned pool cleaning robot, the longitudinal section of the inclined plane is arc-shaped.

[0009] Furthermore, in the aforementioned pool cleaning robot, the anti-clogging structure is a serrated structure or a columnar protrusion structure, and the serrated structure or columnar protrusion structure is disposed near the front end of the pool cleaning robot.

[0010] Furthermore, in the aforementioned pool cleaning robot, the extended structure forms an acute angle with the front end direction of the pool cleaning robot.

[0011] Furthermore, in the aforementioned pool cleaning robot, the extended structure is snapped into the chassis.

[0012] Furthermore, in the aforementioned pool cleaning robot, the water inlet area at the connection between the extended structure and the suction port is greater than or equal to the water inlet area of ​​the suction port.

[0013] Furthermore, in the aforementioned pool cleaning robot, the longitudinal section of the extended structure is a tapered structure from the connection point of the suction port to its free end.

[0014] Furthermore, in the aforementioned pool cleaning robot, the distance between the extended structure and the walking surface of the pool cleaning robot is 5-20mm.

[0023] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the concept or scope of this invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0024] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of the pool cleaning robot proposed according to this utility model. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0026] The water tank cleaning robot provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] See Figure 1 This illustrates an embodiment of the pool cleaning robot described in this utility model, which includes: a housing 100; a chassis 200; and a suction port 201 provided on the chassis 200 (see...). Figure 2 ); Extended structure 300 (see Figure 3 An extension structure 300 is disposed on the chassis 200 and surrounding the suction port 201. The extension structure 300 is made of flexible material, and the distance between the extension structure 300 and the walking surface of the pool cleaning robot is less than the distance between the suction port 201 and the walking surface. A suction channel 202 is disposed within the housing 100, wherein the suction channel 202 communicates with the suction port 201 and the extension structure 300.

[0028] When the pool cleaning robot is working, debris such as leaves, twigs, and paper adhering to the pool bottom or wall surface enters the suction port 201 through the extended structure 300, and then enters the housing 100 along the suction channel 202 for further processing such as filtration and collection. During this process, the extended structure 300 shortens the distance to the surface to be cleaned, thus ensuring the cleaning effect of the suction port 201 on the surface to be cleaned while maintaining the same suction force. Simultaneously, the extended structure 300 is made of a flexible material, ensuring the pool cleaning robot's ability to overcome obstacles and escape during the cleaning process. Since the pool cleaning robot cleans the surface it walks on during its movement, for ease of description, the "walking surface" is also referred to as the "surface to be cleaned."

[0029] The flexible material described in this invention can be formed from a polymer, such as rubber, or plastics like PE and PVC. When the pool cleaning robot needs to move and pass over obstacles on the surface to be cleaned, if the obstacle's size matches a preset size, the extended structure 300 of the flexible material will deform to allow it to pass over the obstacle instead of being stuck, thus ensuring the pool cleaning robot's passability. When the pool robot encounters larger debris (e.g., pebbles, branches, etc.) on the surface to be cleaned, the extended structure 300 made of the flexible material can also deform so that the debris can smoothly reach the vicinity of the suction port 201, and then be sucked into the suction channel 202 for subsequent filtration, collection, and other processing.

[0030] like Figure 3 As shown in the figure, in one embodiment of the present invention, a pool cleaning robot has an extension structure 300 equipped with an anti-clogging structure 301. This anti-clogging structure 301 prevents debris from accumulating in the corner formed by the extension structure 300 and the chassis 200, thereby further improving the cleaning effect of the pool cleaning robot. Furthermore, if too much debris accumulates in this corner, it will affect the robot's passability, potentially causing excessive resistance and increased power consumption; in severe cases, it may even prevent the robot from moving forward.

[0031] The anti-clogging structure 301 is an inclined surface extending towards the front end of the pool cleaning robot; the inclined surface is made of a flexible material; and its longitudinal section is arc-shaped. Thus, the anti-clogging structure 301 forms a shovel-like shape, further guiding impurities into the suction channel 202, preventing their accumulation there. Based on a similar concept, in specific implementations of this invention, the inclined surface can also be replaced by a serrated structure or a columnar protrusion structure, which is positioned close to the front end of the pool cleaning robot.

[0032] Figure 3In the illustrated embodiment, the extension structure 300 forms an acute angle with the front end direction of the pool cleaning robot. This acute angle ranges from 30 to 80 degrees. When the pool cleaning robot is placed on a horizontal surface, the front end direction refers to the direction of travel of the pool cleaning robot on that horizontal surface. In this case, "the extension structure 300 forms an acute angle with the front end direction of the pool cleaning robot" means that the extension structure 300 forms an acute angle with the direction of travel; in other words, the extension structure 300 is tilted towards the direction of travel of the pool cleaning robot. When the pool cleaning robot is performing cleaning operations, due to the suction effect of the pool cleaning robot, the water flow is opposite to the direction of travel of the pool cleaning robot. Since the extension structure 300 is tilted towards the direction of travel, the water flow and the extension structure 300 form an angled opposing force. Therefore, the opening of the extension structure 300 receives a larger flow rate, thereby enhancing its cleaning efficiency.

[0033] For ease of disassembly and assembly, such as Figure 4 As shown, in this embodiment, the extension structure 300 is installed to the chassis 200 by a snap-fit ​​connection. However, for different reasons, the extension structure 300 can also be installed using other methods.

[0034] Generally, the relationship between the cross-sectional area of ​​the extension structure 300 and the water inlet area of ​​the suction port 201 is not limited; that is, the cross-sectional area of ​​the extension structure 300 can be greater than, less than, or equal to the water inlet area of ​​the suction port 201. However, to further improve suction efficiency and fully utilize the suction port 201, this invention is more preferably such that the water inlet area at the connection between the extension structure 300 and the suction port is greater than or equal to the water inlet area of ​​the suction port.

[0035] To achieve better obstacle-crossing performance, the longitudinal section of the extension structure 300 is tapered from the connection point of the suction port to its free end. During the robot's movement, the closer it is to the free end of the extension structure 300, the more numerous and larger the obstacles it encounters. Since the elasticity of flexible materials is related to their thickness, the more elastic the tapered extension structure 300 is near its free end, the easier it is for the free end to deform upon contact with obstacles. Conversely, the portion near the suction port, due to its thicker material, is less prone to deformation, thus ensuring a secure connection between the two.

[0036] Typically, in a specific implementation of this utility model, the distance between the extension structure 300 and the walking surface of the pool cleaning robot is 5-20mm, preferably 10mm.

[0037] It should be noted that the order of the above embodiments is merely for descriptive purposes and does not represent the superiority or inferiority of the embodiments. The processes depicted in the accompanying drawings do not necessarily require a specific or sequential order to achieve the desired result. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

[0038] The above description is merely an exemplary embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope described in this application, and these should all be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
