[0030] Hereinafter, exemplary embodiments of the present application will be described in more detail with reference to the accompanying drawings. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the concept or scope of the present application. Therefore, the drawings and descriptions are considered to be illustrative in nature and not restrictive. These embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present application.

[0031] Various structural schematic diagrams according to embodiments of the present application are shown in the accompanying drawings. These figures are not drawn to scale, and for the purpose of clear expression, some details are magnified and some details may be omitted. The various structures and shapes of the devices shown in the figures, as well as the relative sizes and positional relationships therebetween are merely exemplary and may deviate in practice due to manufacturing tolerances or technical limitations, and those skilled in the art may design them separately as needed. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application.

[0032] The present application provides an automatic pool cleaning device, comprising: a housing; a handle disposed at the front of the housing; and a rear drain disposed at the rear of the housing; wherein the distance between the projections of the handle and the rear drain on the side of the automatic pool cleaning device is greater than or equal to a first predetermined distance. When an external force acts on the handle to lift the automatic pool cleaning device upward, the relative positional relationship between the handle and the rear drain allows for the convenient and smooth drainage of accumulated water within the device, accelerating drainage, thereby improving pool cleaning efficiency and enhancing the user experience.

[0033] The automatic swimming pool cleaning device of the present application is described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 As shown, the present application provides an automatic swimming pool cleaning device 100. Specifically, the automatic swimming pool cleaning device 100 includes: a housing 110, a handle 120 and a drain 130.

[0035] The automatic pool cleaning device 100 may be, for example, a robot configured to perform mobile cleaning within a pool-shaped structure, such as a swimming pool, a reservoir, a water tank, or a water trough. Unless otherwise specified, the following description of the pool-shaped structure will use a swimming pool as an example, and the description of the automatic pool cleaning device will use a robot as an example.

[0036] The housing 110 can be, for example, the outer shell of the robot, which can play the role of support, stability, protection, isolation, and beauty. Figure 1 The robot moves in the direction of the arrow shown, and accordingly, the end of the robot corresponding to the moving direction is the front of the shell, and the end corresponding to the direction opposite to the moving direction is the rear of the shell.

[0037] In one embodiment, the housing 110 can be made of one or more of plastic, polymer organic materials, or metal, providing excellent resistance to compression, bending, and torsion. This provides support for the device's internal mechanical structure, circuit boards, and precision components, withstands water pressure from all directions, and ensures stable operation of the internal components under various operating conditions. Spraying, electroplating, and other techniques can be employed, along with rounded edges, to impart a glossy finish to the housing 110, enhancing both aesthetics and durability.

[0038] like Figure 1 As shown, a handle 120 is provided at the front of the housing for a user to grasp or hold the robot 100 when lifting or moving the robot.

[0039] In one embodiment, the handle 120 can be made of lightweight materials and connected to the housing 110 through various methods, such as riveting, welding, and bolting. Preferably, the handle has a cross-section that is cylindrical, elongated, or otherwise convenient for the user to grip. The above description of the handle is illustrative and is not intended to limit the scope of the handle. Those skilled in the art will be able to select a handle that can implement the technical principles of this application. The position and structure of the handle 120 will be described in detail below in conjunction with specific embodiments.

[0040] like Figure 1 As shown, the drain port 130 is provided at the rear of the housing. When the robot 100 is lifted out of the water, the drain port 130 can drain the water in the robot 100 in time.

[0041] In one embodiment, the drain outlet 130 is composed of a plurality of grille openings of the same size arranged with a certain gap. The size of the gap is related to the drainage efficiency, and the size of the gap can be selected and set on the basis of ensuring stability. The drain outlet is connected to the internal pipes and other components of the machine to coordinate drainage. The above description of the drain outlet is exemplary and is not intended to limit the scope of the drain outlet. Those skilled in the art can select the drain outlet as long as the technical principles of this application can be implemented. The position of the drain outlet 130 will be described in detail below in conjunction with specific embodiments.

[0042] like Figure 1 、 Figure 2 As shown, the distance between the projections of the handle 120 and the drain outlet 130 on the side of the robot 100 is the projection spacing, which is greater than or equal to a first predetermined distance. The first predetermined distance will be described below in conjunction with specific implementations and drawings.

[0043] It should be understood that in the accompanying drawings, in order to schematically illustrate the design principles of the present application, the projection of the handle 120 on the side of the robot 100 is drawn as a line segment, and the projection of the drain outlet 130 on the side of the robot 100 is drawn as a curve. However, the projection of the handle 120 on the side of the robot 100 is not limited to a line segment, and the projection varies with the shape and structure of the handle 120. Similarly, the projection of the drain outlet 130 on the side of the robot 100 is not limited to a curve, and the projection varies with the shape and structure of the drain outlet 130.

[0044] In one embodiment, if Figure 2 As shown, the distance between the projections of the handle 120 and the drain outlet 130 on the side of the robot, i.e., the projection spacing, can be the average of the distances between the two end points of the projection of the handle 120 and the two end points of the projection of the drain outlet 130, or the distance between the midpoint of the projection of the handle 120 and the midpoint of the projection of the drain outlet 130. The projection spacing should be greater than or equal to the first predetermined distance to increase the distance between the handle and the drain outlet. Since the drain outlet 130 is provided at the rear of the shell 110, when the user lifts the robot 100, the handle 120 usually rotates with the rear of the shell 110 as a fulcrum (roughly equivalent to the position of the drain outlet 130). Accordingly, according to the torque formula, the larger the projection distance between the handle 120 and the drain outlet 130, the larger the force arm between the handle 120 and the drain outlet 130. Therefore, when the user needs to lift the robot to drain water, the user only needs to apply a small force to the handle to rotate the robot around the rear of the shell 110, and adjust it from a horizontal posture to a nearly vertical posture, thereby achieving the effect of accelerating drainage. The above description of calculating the projection distance is exemplary and is not intended to limit the calculation method. Those skilled in the art can choose the calculation method as long as the technical principles of this application can be implemented. In practice, the more lines connecting the projections, the closer the calculated projection distance is to the true value.

[0045] To illustrate the first predetermined distance, the concept of sampling points is introduced here. Sampling points are points distributed at predetermined positions on the surface of the housing 110 .

[0046] In one embodiment, two sampling points are preset, one sampling point located at the front of the housing 110, and the other sampling point located at the rear of the housing 110. The first predetermined distance is the distance between the projection points of the two sampling points on the side of the robot, or the projection length of the line connecting the two sampling points on the side of the robot 100.

[0047] In one embodiment, the number of sampling points may be greater than two (e.g., an even number greater than two), and the sampling points may be divided into two groups, front and rear. The sampling points on the front of the housing 110 constitute the first group, and the sampling points on the rear of the housing 110 constitute the second group. The first predetermined distance is equal to the arithmetic mean, variance, or median of the projection lengths of a line connecting the front and rear sampling points in a predetermined manner on the side of the automatic pool cleaning device, or is equal to the distance between the projections of the front and rear sampling points on the side of the robot in a predetermined manner.

[0048] In one embodiment, if Figure 1 、 Figure 3 As shown, the sampling points are divided into two groups, with a predetermined number of 3, totaling six sampling points. The front of the housing 110 is distributed with housing front sampling points 210, 220, 230, and the rear of the housing is distributed with housing rear sampling points 240, 250, 260.

[0049] The predetermined connection pattern can be a "one-to-many" connection between two groups of sampling points. For example, the first predetermined distance is equal to the arithmetic mean of the projected lengths of the lines between sampling points 210, 220, and 230 and sampling points 240, 250, and 260, respectively, on the side of the robot, that is, the arithmetic mean of the projected lengths of the following nine lines on the side of the robot: (210, 240), (210, 250), (210, 260), (220, 240), (220, 250), (220, 260), (230, 240), (230, 250), (230, 260). Specifically, the distance L1 between the front sampling point 210 and the rear sampling point 240 is measured, the distance L2 between the front sampling point 210 and the rear sampling point 250 is measured, and the distance L3 between the front sampling point 210 and the rear sampling point 260 is measured; the distance L4 between the front sampling point 220 and the rear sampling point 240 is measured, the distance L5 between the front sampling point 220 and the rear sampling point 250 is measured, and the distance L6 between the front sampling point 220 and the rear sampling point 250 is measured. and the rear sampling point 260; measuring the distance L7 between the front sampling point 230 and the rear sampling point 240, measuring the distance L8 between the front sampling point 230 and the rear sampling point 250, and measuring the distance L9 between the front sampling point 230 and the rear sampling point 260; calculating the arithmetic mean of the above sampling distances L1, L2, L3, L4, L5, L6, L7, L8, and L9, and the obtained value is the first predetermined distance.

[0050] The predetermined connection can be a one-to-one connection between the front and rear sampling points. For example, the first predetermined distance is equal to the arithmetic mean of the projected lengths of the following three lines on the side of the robot: (210, 260), (220, 250), and (230, 240). Specifically, the distance S1 between the front sampling point 210 and the rear sampling point 260 is measured, the distance S2 between the front sampling point 220 and the rear sampling point 250 is measured, and the distance S3 between the front sampling point 230 and the rear sampling point 240 is measured. The arithmetic mean of the above sampling distances S1, S2, and S3 is calculated, and the resulting value is the first predetermined distance.

[0051] The above description of the average value of the sampling distance is exemplary. Those skilled in the art can set the sampling points according to the specific parameters of the robot (such as shape, size, weight distribution, etc.) as long as the technical principles of this application can be implemented.

[0052] It can be understood that the more sampling points there are and the wider the distribution of the sampling points, the better the drainage efficiency of the robot 100 when it is lifted by the user when the distance between the handle 120 and the drain outlet 130 is greater than or equal to the first predetermined distance calculated in this way.

[0053] like Figure 1 、 Figure 4 As shown, when an external force acts on the handle to lift the robot 100 upward, a line connecting the projections (or the center points of the projections) of the handle 120 and the drain outlet 130 on the side of the automatic pool cleaning device forms a certain angle α with the horizontal plane. In one embodiment, the angle α is greater than 80 degrees and less than or equal to 90 degrees.

[0054] Preferably, the line connecting the center points of the projections of the handle 120 and the drain outlet 130 on the side of the robot 100 is perpendicular to the horizontal, that is, the angle between the line and the horizontal plane is 90 degrees. In this case, the relative position of the handle and the drain outlet is exactly perpendicular or substantially perpendicular to the horizontal plane, allowing water to flow downward through the drain outlet in a relatively short path and at a relatively fast speed. Given the variability and uncertainty in actual operation, this ideal situation is generally not guaranteed. However, an angle between 80 and 90 degrees can achieve a balance between drainage efficiency and operational convenience.

[0055] like Figure 5A As shown, under external force ( Figure 5AWhen the handle 120, the drain outlet 130, and the center of gravity of the robot 100 are projected onto the side of the robot 100 by acting on the handle 120 (in the direction indicated by the arrow in the middle). Due to the complexity of the internal structure of the robot 100, the diversity of the material properties used, and the change in the amount of water remaining in the robot 100, the position of the center of gravity of the robot 100 may change during the process of the robot 100 being lifted out of the water and draining through the drain outlet 130. Therefore, in actual application, the center of gravity may shift. Figure 5A 、 Figure 5B As shown, such an offset may be that the center of gravity of the robot 100 is offset toward the bottom surface 111 of the robot 100, for example, Figure 5B The center of gravity position (center of gravity G1) shown is Figure 5A The illustrated center of gravity position (center of gravity G) is closer to the bottom surface 111 of the robot 100 .

[0056] In one embodiment, the projections of the handle 120, the drain outlet 130, and the center of gravity of the robot 110 on the side of the robot are located on the same straight line. Figure 5A As shown, on the side of the robot 100, the center point of the projection of the handle 120 on the side of the robot 100, the center point of the projection of the drain outlet 130 on the side of the robot 100, and the center of gravity G of the robot 100 are all located on the same straight line. At this time, the relative position of the handle and the drain outlet is exactly perpendicular to the horizontal plane, so water can flow through the drain outlet in a relatively short path and at a relatively fast speed.

[0057] In another embodiment, the projection of the center of gravity of the robot 110 on the side of the robot is located near the line connecting the projections of the handle 120 and the drain outlet 130 on the side of the robot. In other words, the projection of the center of gravity of the robot 110 on the side of the robot is located near the line connecting the projection of the handle 120 on the side of the robot and the projection of the drain outlet 130 on the side of the robot. Figure 5B As shown, the center of gravity G1 of the robot 100 is relative to Figure 5A The center of gravity G shown in FIG is offset, but due to the effect of gravity, the line connecting the projection of the handle 120 on the side of the robot 100 and the projection of the center of gravity G1 on the side of the robot 100 ( Figure 5B Alternatively, the line between the center point of the projection of the handle 120 on the side of the robot 100 and the projection of the center of gravity G1 of the robot 100 on the side of the robot 100 is perpendicular to the horizontal plane. In this embodiment, the center of gravity G1 is located on the line between the projection of the handle 120 on the side of the robot 100 and the projection of the drain outlet 130 on the side of the robot 100 ( Figure 5B The left side of the dashed line L2 in FIG, and the vertical distance between the projection point of the center of gravity G1 and the connecting line is less than or equal to a predetermined length. Preferably, the predetermined length is 10 mm. More preferably, the predetermined length is 5 mm.

[0058] like Figure 1 、 Figure 6 As shown, the housing 110 includes a bottom surface 111 and a rear surface 112. The bottom surface is located at the bottom of the housing, and the rear surface is located at the rear of the housing. The intersection between the bottom surface 111 and the rear surface 112 is a first intersection. The distance between the drain port 130 and the first intersection is less than or equal to a second predetermined distance.

[0059] In one example, the second predetermined distance can be one-quarter of the height / length of the fuselage. The drain outlet 130 can be located above the first junction, for example, on the rear surface 112, and the distance between the drain outlet 130 and the first junction is less than or equal to the second predetermined distance; the drain outlet 130 can also be located below the first junction, for example, on the bottom surface 111, and the distance between the drain outlet 130 and the first junction is less than or equal to the second predetermined distance. The second predetermined distance can be, for example, one-quarter of the height / length of the fuselage. The size of the second predetermined distance can be adaptively selected according to the size, shape, weight distribution, center of gravity position, etc. of the robot 100, as long as the principles of the present application can be implemented.

[0060] like Figure 1 、 Figure 4 and Figure 6 As shown, the shell 110 includes a rear surface 112 and a bottom surface 111, the rear surface 112 is located at the rear of the shell 110, the bottom surface 111 is located at the bottom of the shell 110, and the drain outlet 130 is arranged at the first junction between the rear surface 112 and the bottom surface 111.

[0061] like Figure 1 、 Figure 7 As shown, the housing 110 includes a top surface 113 and a front surface 114 , wherein the top surface is located at the top of the housing, and the front surface is located at the front of the housing. The junction between the top surface 113 and the front surface 114 is a second junction.

[0062] In one example, the handle 120 is provided at the second junction.

[0063] In another embodiment, the handle 120 may be located above the second junction, such as on the top surface 113, with the distance between the handle and the second junction being less than or equal to a third predetermined distance. In yet another embodiment, the handle 120 may be located below the second junction, such as on the front surface 114, with the distance between the handle and the second junction being less than or equal to a third predetermined distance. The third predetermined distance may be, for example, one-quarter the height / length of the robot body. The third predetermined distance may be adaptively selected based on the size, shape, weight distribution, center of gravity location, etc. of the robot 100, as long as the principles of the present application are implemented.

[0064] like Figure 1 、 Figure 7 As shown, the handle 120 includes a main body 121 and a connecting member 122. The main body 121 is parallel to the front surface 114, and two ends of the connecting member 122 are connected to the main body 121 and the front surface 114 respectively.

[0065] In one embodiment, those skilled in the art can select the material, shape, and size of the main body 121 to improve the user's grip experience. For example, the main body 121 can be made of lightweight materials to reduce the weight and volume of the handle, thereby reducing the overall weight of the robot. For example, the cross-section of the handle can be cylindrical, elongated, or other shapes that are easy for the user to grip, making it easier for the user to move and lift the robot. Preferably, the handle surface can be treated with an anti-slip treatment to ensure a secure grip even in wet environments.

[0066] In one embodiment, those skilled in the art can select the material and connection method of the connector 122. For example, the connector 122 can be made of plastic, polymer organic material, or metal (alone or in combination) to impart high strength. The connector 122 can be made of one or more of plastic, polymer organic material, and metal to provide excellent strength. The connector 122 can be connected to the main body 121 and the front surface 114 in a variety of ways, such as riveting, welding, and bolting to achieve a stable connection.

[0067] In summary, according to the automatic pool cleaning device provided by this application, when an external force acts on the handle to lift the automatic pool cleaning device upward, the positional relationship and layout design of the handle and the drain port can conveniently and smoothly drain accumulated water inside the device, achieving an accelerated drainage effect. This improves the drainage efficiency of the automatic pool cleaning device compared to traditional designs, thereby improving the overall cleaning efficiency of the pool. As the market matures in the future, there is reason to believe that this application will bring a more convenient and efficient pool cleaning experience to users in more homes and professional settings.
