Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cleaning tools, specifically to a pool robot and a pool cleaning system. Background Technology
[0002] A pool robot is an intelligent device used for cleaning and maintaining swimming pools. It is typically driven by an electric motor, using an impeller to generate water flow, propelling the robot within the pool. It can perform comprehensive cleaning of the pool bottom, walls, and waterline, effectively removing sand, leaves, dirt, and other debris. Some high-end pool robots are also equipped with brushless motors, offering advantages such as high efficiency, low noise, and long lifespan. The pool robot draws water from the pool through its suction port, filters it through an internal filter to remove impurities, dirt, and dust, and then discharges the filtered water back into the pool, thus achieving the purpose of cleaning. Some pool robots have an automatic recharging function; when the battery is low, they can automatically return to the charging dock to recharge, and then continue cleaning tasks without human intervention. However, traditional pool robots cannot detect the space beneath them, cannot accurately determine the height of the steps, and cannot precisely navigate up and down steps, which can easily cause the robot to tip over.

[0034] This utility model provides a pool robot 100. For details, please refer to [link / reference needed]. Figures 1 to 3In this embodiment, the pool robot 100 includes a robot body 1 and a detection device 2. The detection device 2 includes at least a first detection component 21 and a second detection component 22 disposed at the bottom of the robot body 1, and a third detection component (not shown in the figures) disposed at the front end of the robot body. The robot body 1 has a central axis S1 extending in a front-rear direction. In the direction of travel of the robot body 1, the first detection component 21 is located to the left of the central axis S1, and the second detection component 22 is located to the right of the central axis S1.
[0035] In this embodiment, a first detection component 21 and a second detection component 22 are provided at the bottom of the robot body 1. These components detect the distance between the platform below and the bottom of the robot body 1. The first detection component 21 is positioned near the left side of the bottom of the robot body 1, and the second detection component 22 is positioned near the right side. This allows for the detection of the distances from objects on the left side of the bottom of the robot body 1 and around its left side, as well as from objects on the right side of the bottom of the robot body 1 and around its right side, resulting in a wider and more comprehensive detection range. Furthermore, the first detection component 21 on the left and the second detection component 22 on the right can better identify the position of the bottom step, determining whether it is on the left or right side of the robot body 1, thus enabling more precise movement of the pool robot 100 when descending steps. Finally, by placing a third detection component at the front end of the robot body 1, the height of the step can be better determined when the pool robot 100 is climbing the step. Therefore, it is easier and more efficient to go up and down stairs, which can better protect the pool robot 100 and improve the user experience.
[0036] Among them, combined Figure 1 and Figure 2As shown, the robot body 1 includes a body 11 and walking mechanisms 12 disposed on both sides of the body 11. The body 11 is generally rectangular, with its length along its direction of travel. The walking mechanism 12 includes two track structures, which are respectively disposed on both sides of the width direction of the body 11. When the pool robot 100 is moving normally, its forward direction is in front of the body 11, and its backward direction is behind the body 11. The two track structures are located on the left and right sides of the body 11, respectively. In this invention, unless otherwise specified, descriptions of orientations are based on this. The central axis S1 extending in the front-rear direction of the robot body 1 is the central axis of symmetry in the left-right direction of the projection of the body 11 onto the horizontal plane. The first detection component 21 and the second detection component 22 are respectively set on the left and right sides of the bottom of the body 11, so that all areas below the pool robot 100 can be detected by the pool robot 100, so that the pool robot 100 can better determine the distance between the bottom of the pool and the body 11, and better know the height of the steps when climbing.
[0037] In one embodiment, the first detection component 21 can be positioned close to the front end of the robot body 1. The second detection component 22 is positioned close to the rear end of the robot body 1. When the pool robot 100 climbs the steps, the first detection component 21, located at the front end of the body 11, has a detection field of view that better covers the front and bottom areas of the body 11. Therefore, when the pool robot 100 climbs the steps, the first detection component 21 can better detect the climbing height of the steps, thus enabling precise control of the pool robot 100 to lift. Similarly, when the pool robot 100 descends the steps, because the second detection component 22 is located at the front end of the body 11, the first detection component 21's detection field of view can better cover the front and bottom areas of the body 11. Therefore, when the pool robot 100 climbs the steps, the first detection component 21 can better detect the climbing height of the steps, thus enabling precise control of the pool robot 100 to lift.
[0038] In another embodiment, the third detection component can be located on the left side of the central axis S1, and the detection device 2 further includes a fourth detection component located on the right side of the robot body 1. The third detection component at the front end can detect obstacles at the front of the robot body 1 and detect the height of steps during climbing. The fourth detection component on the right side can detect objects on the right side of the robot body 1, thereby better adjusting the distance between the robot body 1 and the pool wall. Furthermore, the first detection component 21 and the second detection component 22 detect the bottom area of the robot body 1, thereby better adjusting the distance between the robot body 1 and the bottom area, making the pool robot 100 more flexible during operation.
[0039] Preferably, the first detection component 21 and the second detection component 22 are both located close to the front end of the robot body 1, and are symmetrically arranged on both sides of the central axis S1. This allows for better detection of the left and right detection areas below the bottom of the robot body 1, and improves the avoidance of the left and right sides by the pool robot 100. For example, the first detection component 21 and the second detection component 22 can both be located close to the middle area of the bottom surface 111 of the body 11, and symmetrically located on the left and right sides of the bottom of the body 11. This allows for symmetrical detection of the left and right sides below the body 11, while also ensuring uniform detection of the front and rear areas of the body 11, thus guaranteeing a uniform detection effect.
[0040] Of course, in another embodiment, multiple first detection components 21 may be provided, and the multiple first detection components 21 are arranged at intervals along the front-back direction of the robot body 1. Multiple second detection components 22 may also be provided, and the multiple second detection components 22 are arranged at intervals along the front-back direction of the robot body 1. The coverage area of the first detection components 21 and the second detection components 22 is wider, thereby the detection range is also wider, and the detection is more accurate.
[0041] Preferably, both the first detection component 21 and the second detection component 22 are ultrasonic sensors. The ultrasonic sensors can detect the distance between the target object (such as the bottom of the pool, the pool wall, or the steps) and the bottom of the robot body 11, making the movement of the pool robot 100 more precise and accurate.
[0042] In one embodiment, such as Figure 3 As shown, a suction port 4 and a scraper 3 surrounding the suction port 4 are provided at the bottom of the robot body 1. The scraper 3 is open in the front area corresponding to the suction port 4, and the first detection component 21 is located outside the area formed by the scraper 3. The scraper 3 is roughly U-shaped and does not obstruct the front area of the suction port 4. When the pool robot 100 is cleaning normally and moving forward, the sewage can be surrounded by the suction port 4 under the action of the scraper 3, so that the sewage can be better sucked into the pool robot 100 through the suction port 4. When the first detection component 21 is set near the front end of the robot body 1, the first detection component 21 is set outside the area formed by the scraper 3, so that less sewage can flow through the first detection component 21, thereby better avoiding the first detection component 21 being blocked by dirt and ensuring the sensitivity of the first detection component 21. Among them, the scraper 3 can be set as a rubber strip, which can make closer contact with the surface to be cleaned (such as the bottom surface 111 of the pool and the wall surface), thus achieving a better scraping effect.
[0043] Furthermore, such as Figure 3As shown, the scraper 3 has two scraping sections arranged opposite each other along the left-right direction of the robot body 1. The distance between the two scraping sections gradually decreases in the direction from front to back along the robot body 1. That is, in the direction of movement of the robot body 1, the two scraping sections can guide the sewage towards the suction port 4, so that the dirt can enter the suction port 4 more effectively.
[0044] Furthermore, the first detection component 21 is positioned close to the open side of the scraper 3 and outside the straight line between the two scraping sections. The first detection component 21 can better avoid the path through which the sewage flows and can better detect the front end and left side area of the robot body 1.
[0045] Furthermore, the second detection component 22 is also positioned near the rear end of the bottom of the robot body 11. Specifically, the robot body 1 has a bottom surface 111 and a rear end surface, as well as a transition surface 112 connecting the bottom surface 111 and the rear end surface. The transition surface 112 is arc-shaped, and the second detection component 22 is disposed on the transition surface 112. This allows the detection field of view of the second detection component 22 to face the bottom of the robot body 11, while at least partially facing the front of the robot body 11, thereby better improving the detection range of the pool robot 100.
[0046] Furthermore, the walking mechanism 12 is designed with a walking surface suitable for contacting the traveling surface. This walking surface protrudes from the bottom surface 111 of the robot body 1, preventing the body 11 of the pool robot 100 from rubbing against the traveling surface during movement, thus better protecting the body 11. Both the first detection component 21 and the second detection part protrude from the bottom surface 111 of the robot body 1, and the protrusion height of the first detection component 21 and the second detection component 22 is less than the protrusion height of the walking surface. This reduces the obstruction of the first detection component 21 and the second detection part by the body 11, thereby increasing the detection field of view of the first detection component 21 and the second detection part 22, while also preventing scratches on the first detection component 21 and the second detection part 22, thus better protecting them.
[0047] Of course, in another embodiment, the first detection component 21 and the second detection component 22 can be mounted on a telescopic frame. When bottom detection is not required, the first detection component 21 and the second detection component 22 can be retracted inside the bottom surface 111 of the fuselage 11 to prevent contamination of the first detection component 21 and the second detection component 22. When bottom detection is required, the first detection component 21 and the second detection component 22 can be protruded from the bottom surface 111 of the fuselage 11 by telescopic movement of the telescopic frame, thereby expanding the detection angle and making the detection more accurate.
[0048] Alternatively, a shield can be provided on the outside of the first detection component 21 and the second detection component 22, and the shield can be in an open and closed state. In the closed state, the first detection component 21 and the second detection component 22 are shielded by the shield, forming protection; in the open state, the first detection component 21 and the second detection component 22 are exposed to facilitate detection.
[0049] It is understood that the detection device 2 may also include multiple third detection components, which are arranged around the periphery of the robot body 11. For example, at least one third detection component may be located on the front, rear, left, and / or right side of the body 11. This allows the pool robot 100 to detect obstacles around its periphery more comprehensively and move more sensitively during operation.
[0050] In addition, such as Figure 3 As shown, a cleaning roller brush is also provided at the front end of the bottom of the robot body 1. The cleaning roller brush is rotatably mounted on the robot body 1, and its axis extends along the left and right direction of the robot body 1. The cleaning roller brush is located between the two track structures of the walking mechanism 12, and the length of the cleaning roller brush in the left and right direction is greater than the length of the scraper 3 in the left and right direction. This allows the dirt rolled up by the cleaning roller brush to enter the area enclosed by the scraper 3 more effectively, and the dirt to enter the suction port 4 more effectively, resulting in a better cleaning effect.
[0051] This utility model also provides a swimming pool cleaning system, including the aforementioned swimming pool robot 100. The swimming pool robot 100 moves more flexibly and moves up and down steps more accurately, making the swimming pool robot 100 return to its original position faster, which can effectively improve the cleaning efficiency of the swimming pool cleaning system.
[0052] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
