Description

Buoyancy devices and cleaning robots

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on March 25, 2024, with application number 202410342566.6, and invention name “Buoyancy device and cleaning robot”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of robots, and in particular to a buoyancy device and a cleaning robot. Background Art

[0003] With the advancement of technology, cleaning robots that can clean up garbage have emerged. Generally speaking, cleaning robots are usually able to perform land operations. At present, various dirt, garbage, etc. will float on the surface of pools, swimming pools, rivers, lakes, etc. after long-term use, which will cause serious pollution to the water quality or affect the appearance, so the water surface needs to be cleaned. However, the cleaning robots used for land operations in the related art and the robots used for water surface cleaning require a buoyancy device when cleaning the water surface. However, the buoyancy device in the related art is large and bulky, or when the buoyancy device is applied to the cleaning robot, the cleaning robot is large and bulky, which makes it inconvenient for the cleaning robot to operate on the water surface. Summary of the Invention

[0004] In a first aspect, an embodiment of the present application provides a buoyancy device for a cleaning robot, the buoyancy device comprising:

[0005] a first buoyancy member, used to correspond to the bottom side of the main body of the cleaning robot, wherein the interior of the first buoyancy member is hollow to form a first buoyancy chamber;

[0006] a second buoyancy member, used to correspond to the left side of the main body of the cleaning robot, the second buoyancy member being connected to one side of the first buoyancy member, the interior of the second buoyancy member being hollow to form a second buoyancy chamber;

[0007] a third buoyancy member, used to correspond to the right side of the main body of the cleaning robot, the third buoyancy member being connected to the other opposite side of the first buoyancy member, the interior of the third buoyancy member being hollow to form a third buoyancy chamber;

[0008] The first buoyancy member, the second buoyancy member and the third buoyancy member together form an accommodating space for accommodating the main body of the cleaning robot.

[0009] Embodiments of the present application provide a buoyancy device comprising a first buoyancy member, a second buoyancy member, and a third buoyancy member. The first, second, and third buoyancy members collectively form a housing for a cleaning robot body, and the buoyancy device is used to keep the cleaning robot body afloat. The first buoyancy member is disposed on the bottom of the cleaning robot body, while the second and third buoyancy members are disposed on the sides of the cleaning robot body. Because the buoyancy device includes the first buoyancy member, the first buoyancy member can provide buoyancy. Therefore, when the buoyancy device supports the cleaning robot body of a predetermined weight, the second and third buoyancy members do not need to be excessively large, thereby making the buoyancy device relatively compact and uncomplicated. When the buoyancy device is used in a cleaning robot, the cleaning robot is relatively compact and uncomplicated, facilitating its operation on the water surface and enabling the cleaning robot to function effectively even in confined water environments.

[0010] In a second aspect, an embodiment of the present application provides a cleaning robot, comprising: a buoyancy device as described in the first aspect or any one embodiment of the first aspect; and a body, wherein the body is accommodated in a accommodating space of the buoyancy device.

[0011] In summary, the buoyancy device provided in the embodiments of the present application includes a first buoyancy member, a second buoyancy member, and a third buoyancy member. The first buoyancy member, the second buoyancy member, and the third buoyancy member together form a storage space for accommodating the main body of the cleaning robot. The buoyancy device is used to float the main body of the cleaning robot on the water surface. In addition, because the interior of the first buoyancy member is hollow to form a first buoyancy chamber, the interior of the second buoyancy member is hollow to form a second buoyancy chamber, and the interior of the third buoyancy member is hollow to form a third buoyancy chamber, the buoyancy device has a relatively large buoyancy and can float the heavier main body of the cleaning robot. The first buoyancy member is used to correspond to the bottom side of the cleaning robot's fuselage body, the second buoyancy member is used to correspond to the left side of the cleaning robot's fuselage body, and the third buoyancy member is used to correspond to the right side of the cleaning robot's fuselage body. The first buoyancy member can provide buoyancy. Therefore, when the buoyancy device carries the cleaning robot's fuselage body of a preset weight, the volume of the second buoyancy member and the third buoyancy member of the buoyancy device does not need to be set too large, thereby making the buoyancy device relatively small and not bloated. When the buoyancy device is used in a cleaning robot, the cleaning robot is small and not bloated, which facilitates the cleaning robot to operate on the water surface. It can work well even in a relatively narrow environment on the water surface. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] The terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish between different objects, not to describe a particular order.

[0027] References herein to "embodiments" or "implementations" mean that a particular feature, structure, or characteristic described in connection with the embodiments or implementations may be included in at least one embodiment of the present application. The appearance of such phrases in various places in the specification does not necessarily refer to the same embodiment, nor do they constitute independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] An embodiment of the present application provides a buoyancy device of a cleaning robot and a cleaning robot. Next, the buoyancy device of the cleaning robot and the cleaning robot provided in the embodiment of the present application are described in detail.

[0029] Please refer to Figures 1 and 2. Figure 1 is a schematic diagram of the three-dimensional structure of a cleaning robot provided in one embodiment of the present application; Figure 2 is a schematic diagram of the cleaning robot shown in Figure 1 from another angle. The cleaning robot 1 includes a buoyancy device 10 and a main body 30. The buoyancy device 10 is capable of floating on the water surface. The main body 30 is supported by the buoyancy device 10, and the main body 30 floats on the water surface under the action of the buoyancy device 10. In other words, the buoyancy device 10 is used to float the main body 30 on the water surface. The main body 30 is the main body of the cleaning robot 1 that performs the garbage cleaning function. The main body 30 of the cleaning robot 1 can be used to clean garbage from water surfaces such as pools, swimming pools, rivers, and lakes. It can be understood that the main body 30 of the cleaning robot 1 can be used to clean garbage from water surfaces (referred to as water surface cleaning) is one function of the main body 30 of the cleaning robot 1 and should not be understood as the only function of the main body 30 of the cleaning robot 1. In other embodiments, the main body 30 of the cleaning robot 1 can be used for not only water surface cleaning but also one or more of underwater cleaning, water surface cleaning, and land cleaning. The present application does not limit the function of the main body 30 of the cleaning robot 1, as long as it can perform water surface cleaning.

[0030] Next, the buoyancy device 10 in the cleaning robot 1 shown in FIG. 1 will be described in detail.

[0031] Please refer to Figures 2 and 3 together. Figure 3 is a schematic diagram of the three-dimensional structure of the buoyancy device in the cleaning robot provided in Figure 1. The buoyancy device 10 includes a first buoyancy member 110, a second buoyancy member 120 and a third buoyancy member 130. The first buoyancy member 110 is used to be arranged corresponding to the bottom side (also called the bottom) of the fuselage main body 30 of the cleaning robot 1. The interior of the first buoyancy member 110 is hollow to form a first buoyancy chamber. The second buoyancy member 120 is used to correspond to the left side of the fuselage main body 30 of the cleaning robot 1. The second buoyancy member 120 is connected to one side of the first buoyancy member 110, and the interior of the second buoyancy member 120 is hollow to form a second buoyancy chamber. The third buoyancy member 130 is used to correspond to the right side of the fuselage main body 30 of the cleaning robot 1, and the third buoyancy member 130 is connected to the other opposite side of the first buoyancy member 110, and the interior of the third buoyancy member 130 is hollow to form a third buoyancy chamber. The first buoyancy member 110 , the second buoyancy member 120 and the third buoyancy member 130 together form an accommodating space 10 a for accommodating the main body 30 of the cleaning robot 1 .

[0032] Because the first buoyancy member 110 is disposed on the bottom side of the main body 30 of the cleaning robot 1, the first buoyancy member 110 is also referred to as the bottom plate. Compared to first buoyancy members without a first buoyancy chamber, the first buoyancy member 110 having a first buoyancy chamber can increase the buoyancy of the first buoyancy member 110. In other words, the first buoyancy member 110 in the buoyancy device 10 provided in the embodiments of the present application has a first buoyancy chamber, resulting in greater buoyancy.

[0033] The second buoyancy member 120 is used to correspond to the left side of the main body 30 of the cleaning robot 1, and the third buoyancy member 130 is used to correspond to the right side of the main body 30 of the cleaning robot 1. Therefore, the first buoyancy member 110 and the second buoyancy member 130 are also called the two side panels of the buoyancy device 10.

[0034] The second buoyancy member 120 has a second buoyancy cavity, thereby enabling the second buoyancy member 120 to have a larger buoyancy. Correspondingly, the third buoyancy member 130 has a third buoyancy cavity, thereby enabling the third buoyancy member 130 to have a larger buoyancy.

[0035] It should be noted that the so-called left side and right side of the main body 30 of the cleaning robot 1 are the left side and right side of the main body 30 determined with the front as the moving direction of the cleaning robot 1. It should be noted that the left side and right side of the main body 30 of the cleaning robot 1 described here are to illustrate that the second buoyancy member 120 and the third buoyancy member 130 are respectively located on opposite sides of the main body 30 of the cleaning robot 1.

[0036] The first buoyancy member 110 , the second buoyancy member 120 and the third buoyancy member 130 together form an accommodating space 10 a , which is used to accommodate the body 30 of the cleaning robot 1 . The buoyancy device 10 is used to float the body 30 of the cleaning robot 1 on the water surface.

[0037] The buoyancy device 10 can float on the water surface. When used with the cleaning robot 1, the buoyancy device 10 can float the main body 30 of the cleaning robot 1 on the water surface. In one embodiment, the density of the first buoyancy member 110, the second buoyancy member 120, and the third buoyancy member 130 is less than the density of water, so that the buoyancy device 10 can float on the water surface. The present embodiment does not impose any restrictions on the material of the buoyancy device 10, as long as the buoyancy device 10 can float on the water surface.

[0038] When the buoyancy device 10 is applied to the cleaning robot 1 , the first buoyancy member 110 is arranged corresponding to the bottom of the main body 30 of the cleaning robot 1 , and the first buoyancy member 110 contacts the water surface to provide buoyancy for the main body 30 of the cleaning robot 1 .

[0039] In summary, the buoyancy device 10 provided in the embodiments of the present application includes a first buoyancy member 110, a second buoyancy member 120, and a third buoyancy member 130. The first buoyancy member 110, the second buoyancy member 120, and the third buoyancy member 130 collectively form a housing space 10a. The housing space 10a is used to accommodate the main body 30 of the cleaning robot 1. The buoyancy device 10 is used to float the main body 30 of the cleaning robot 1 on the water surface. In addition, because the interior of the first buoyancy member is hollow to form a first buoyancy chamber, the interior of the second buoyancy member is hollow to form a second buoyancy chamber, and the interior of the third buoyancy member is hollow to form a third buoyancy chamber, the buoyancy device 10 has a relatively large buoyancy, capable of floating the relatively heavy main body 30 of the cleaning robot 1. The first buoyancy member 110 is used to correspond to the bottom side of the cleaning robot 1's main body 30, the second buoyancy member 120 is used to correspond to the left side of the cleaning robot 1's main body 30, and the third buoyancy member 130 is used to correspond to the right side of the cleaning robot 1's main body 30. The first buoyancy member 110 can provide buoyancy. Therefore, when the buoyancy device 10 carries the cleaning robot 1's main body 30 at a predetermined weight, the second buoyancy member 120 and the third buoyancy member 130 of the buoyancy device 10 do not need to be excessively large, thereby making the buoyancy device 10 relatively compact and unobstructed. When the buoyancy device 10 is used in the cleaning robot 1, the cleaning robot 1 is relatively compact and unobstructed, making it easier for the cleaning robot 1 to operate on the water surface. Even in relatively confined water environments, the cleaning robot 1 can function well.

[0040] Furthermore, in one embodiment, the first float chamber, the second float chamber, and the third float chamber are interconnected.

[0041] The first buoyancy chamber, the second buoyancy chamber, and the third buoyancy chamber are interconnected, so that the buoyancy device 10 has a larger buoyancy and can float the heavier body 30 of the cleaning robot 1 .

[0042] Further, please refer to Figure 4, which is a numbered schematic diagram of another dimension of the buoyancy device shown in Figure 3. In one embodiment, the first buoyancy member 110 includes a main body 111, a first connecting portion 112, and a second connecting portion 113, and the first connecting portion 112 and the second connecting portion 113 are respectively connected to the two opposite ends of the main body 111. The first connecting portion 112 is bent and connected to the second buoyancy member 120. In other words, the second buoyancy member 120 is bent and connected to the first connecting portion 112. The second connecting portion 113 is bent and connected to the third buoyancy member 130. In other words, the third buoyancy member 130 is bent and connected to the second connecting portion 113. In addition, the third buoyancy member 130 and the second buoyancy member 120 are respectively arranged at intervals on the same side of the first buoyancy member 110, and the third buoyancy member 130 and the second buoyancy member 120 are respectively used to correspond to the side arrangement of the main body 30 of the cleaning robot 1.

[0043] The first buoyancy member 110 includes a main body 111, a first connecting portion 112 and a second connecting portion 113. The first connecting portion 112 and the second connecting portion 113 are respectively connected to opposite ends of the main body 111. In other words, the first connecting portion 112, the main body 111 and the second connecting portion 113 are arranged along a first direction D1.

[0044] The main body 111 is a main portion of the first buoyancy member 110. In this embodiment, the main body 111 extends along the first direction D1 or approximately along the first direction D1. The main body 111 may be rectangular or approximately rectangular.

[0045] The first connecting portion 112 extends in a second direction D2, wherein the second direction D2 intersects the first direction D1. In this embodiment, the second direction D2 is perpendicular or approximately perpendicular to the first direction D1. The direction of the second connecting portion 113 is in the second direction D2 or approximately in the second direction D2.

[0046] In this embodiment, the first buoyancy member 110 is an integrated structure; in other embodiments, the main body 111, the first connecting portion 112 and the second connecting portion 113 of the first buoyancy member 110 may also be separate structures.

[0047] The second buoyancy member 120 is bent and connected to the first connection portion 112 . The second buoyancy member 120 is disposed on one side of the first buoyancy member 110 .

[0048] In this embodiment, the first buoyancy member 110 includes a main body 111, a first connecting portion 112, and a second connecting portion 113. The first connecting portion 112 and the second connecting portion 113 are respectively connected to opposite ends of the main body 111. The first connecting portion 112 is connected to the second buoyancy member 120 by a bend. The second connecting portion 113 is connected to the third buoyancy member 130 by a bend. As can be seen, the above structure of the first buoyancy member 110 facilitates the connection of the second buoyancy member 120 and the third buoyancy member 130 to the first buoyancy member 110.

[0049] Further, please refer to Figures 3, 4, and 5. Figure 5 is a schematic diagram illustrating a portion of the structure of the buoyancy device shown in Figure 3. In this embodiment, the thickness of the second buoyancy member 120 at one end adjacent to the first connection portion 112 is greater than the thickness at the other end of the second buoyancy member 120 facing away from the first connection portion 112; and the thickness of the second buoyancy member 120 gradually decreases in a direction away from the first connection portion 112. In addition, the thickness of the third buoyancy member 130 at one end adjacent to the second connection portion 113 is greater than the thickness at the other end of the third buoyancy member 130 facing away from the second connection portion 113; and the thickness of the third buoyancy member 130 gradually decreases in a direction away from the second connection portion 113. The above-mentioned structure of the second buoyancy member 120 and the third buoyancy member 130, on the one hand, the other end of the second buoyancy member 120 away from the first connecting part 112 is thinner, and the other end of the third buoyancy member 130 away from the second connecting part 113 is thinner, which can make the other end of the second buoyancy member 120 away from the first connecting part 112 easier to deform, and the other end of the third buoyancy member 130 away from the second connecting part 113 easier to deform, so as to facilitate the installation of the main body 30 of the cleaning robot 1 in the accommodating space 10a or removal from the accommodating space 10a. On the other hand, the other end of the second buoyancy member 120 away from the first connection portion 112 is thinner, and the other end of the third buoyancy member 130 away from the second connection portion 113 is thinner. This also allows the second buoyancy member 120 and the third buoyancy member 130 to fit well with the main body 30 when the buoyancy device 10 is used to support the main body 30 of the cleaning robot 1. This also makes the overall appearance of the cleaning robot relatively light and thin, with a small and unpretentious size, making it easier for the cleaning robot 1 to operate on the water surface. It can also work well even in a relatively narrow water environment. On the other hand, the end of the second buoyancy member 120 adjacent to the first connection part 112 is thicker, so that the connection strength between the second buoyancy member 120 and the first connection part 112 of the first buoyancy member 110 is higher; the end of the third buoyancy member 130 adjacent to the second connection part 113 is thicker, so that the connection strength between the third buoyancy member 130 and the second connection part 113 of the first buoyancy member 110 is higher; so that the strength of the buoyancy device 10 is higher.

[0050] It is understandable that in other embodiments, the structures of the second buoyancy member 120 and the third buoyancy member 130 may not be limited thereto.

[0051] The second buoyancy member 120 and the third buoyancy member 130 are respectively arranged on the side of the main body 30 of the cleaning robot 1. On the one hand, when the cleaning robot 1 performs water surface cleaning, the second buoyancy member 120 and the third buoyancy member 130 can provide buoyancy, and the second buoyancy member 120, the third buoyancy member 130 and the first buoyancy member 110 cooperate with each other to enable the cleaning robot 1 to float on the water surface; on the other hand, the second buoyancy member 120 and the third buoyancy member 130 can protect the main body 30 of the cleaning robot 1, reducing or even avoiding the main body 30 of the cleaning robot 1 being hit by obstacles on the water surface.

[0052] In this embodiment, the height orientation of the second buoyancy member 120 is in the third direction D3, which intersects the first direction D1 and the second direction D2. The height orientation of the third buoyancy member 130 is in the third direction D3, or approximately in the third direction D3. In this embodiment, the third direction D3 is a direction away from the first buoyancy member 110.

[0053] The height direction of the second buoyancy member 120 is the third direction D3, and the third direction D3 is the direction away from the first buoyancy member 110. Therefore, when the cleaning machine used by the buoyancy device 10 is on the water surface, the second buoyancy member 120 can provide buoyancy away from the water surface, so that the body 30 of the cleaning robot 1 floats on the water surface.

[0054] Generally speaking, when the material and shape of the second buoyancy member 120 are constant, the greater the height of the second buoyancy member 120, the greater the buoyancy it can provide; and the smaller the height of the second buoyancy member 120, the smaller the buoyancy it can provide. In this embodiment, the height of the second buoyancy member 120 protruding from the first buoyancy member 110 can be, but is not limited to, one-half or approximately one-half the height of the main body 30 of the cleaning robot 1. This ensures, on the one hand, that the buoyancy device 10 has sufficient buoyancy, and on the other hand, that the cleaning robot 1 is smaller and less bulky, making it easier for the cleaning robot 1 to operate on the water surface, even in relatively confined water environments.

[0055] The height direction of the third buoyancy member 130 is the third direction D3, or is approximately the third direction D3, and the third direction D3 is the direction away from the first buoyancy member 110. Therefore, when the cleaning robot 1 using the buoyancy device 10 is on the water surface, the third buoyancy member 130 can provide buoyancy away from the water surface, so that the body 30 of the cleaning robot 1 floats on the water surface.

[0056] Generally speaking, given the material and shape of the third buoyancy member 130, the greater the height of the third buoyancy member 130, the greater the buoyancy it can provide; and the smaller the height of the third buoyancy member 130, the smaller the buoyancy it can provide. In this embodiment, the height of the third buoyancy member 130 protruding from the first buoyancy member 110 can be, but is not limited to, half or approximately half the height of the main body 30 of the cleaning robot 1. This ensures, on the one hand, sufficient buoyancy for the buoyancy device 10, and on the other hand, reduces the size of the cleaning robot 1, making it easier for the cleaning robot 1 to operate on the water surface and to function effectively even in relatively confined water environments.

[0057] In this embodiment, the material, shape and structure of the third buoyancy member 130 are the same as those of the second buoyancy member 120 , so as to provide the same buoyancy for the main body 30 of the cleaning robot 1 .

[0058] In summary, the buoyancy device 10 provided in the embodiments of the present application includes a first buoyancy member 110, a second buoyancy member 120, and a third buoyancy member 130. The first buoyancy member 110, the second buoyancy member 120, and the third buoyancy member 130 collectively form a housing space 10a. The housing space 10a is used to accommodate the main body 30 of the cleaning robot 1. The buoyancy device 10 is used to float the main body 30 of the cleaning robot 1 on the water surface. The first buoyancy member 110 is configured to correspond to the bottom of the main body 30 of the cleaning robot 1, and the second buoyancy member 120 and the third buoyancy member 130 are configured to correspond to the sides of the main body 30 of the cleaning robot 1. Because the buoyancy device 10 includes the first buoyancy member 110, which provides buoyancy, when the buoyancy device 10 carries the cleaning robot 1's body 30 at a predetermined weight, the second buoyancy member 120 and the third buoyancy member 130 of the buoyancy device 10 do not need to be excessively large, thereby making the buoyancy device 10 relatively compact and unobstructed. When the buoyancy device 10 is used in the cleaning robot 1, the cleaning robot 1 is compact and unobstructed, making it easier for the cleaning robot 1 to operate on the water surface. Even in relatively confined water environments, the cleaning robot 1 can function effectively.

[0059] In addition, the first buoyancy member 110 includes a main body 111, a first connecting portion 112 and a second connecting portion 113. The first connecting portion 112 and the second connecting portion 113 are respectively connected to the two opposite ends of the main body 111. The second buoyancy member 120 is bent and connected to the first connecting portion 112. The third buoyancy member 130 is bent and connected to the second connecting portion 113. The third buoyancy member 130 and the second buoyancy member 120 are respectively arranged at intervals on the same side of the first buoyancy member 110. The specific structure of the first buoyancy member 110 can facilitate the connection between the first buoyancy member 110 and the second buoyancy member 120, and facilitate the connection between the first buoyancy member 110 and the third buoyancy member 130.

[0060] Please refer to Figure 6, which is a schematic diagram illustrating a portion of the structure of the buoyancy device shown in Figure 3. The main body 111 has a first side wall 1111 and a second side wall 1112 disposed opposite each other. In the schematic diagram of this embodiment, the first side wall 1111 is the side wall at the front of the main body 111, and the second side wall 1112 is the side wall at the rear of the main body 111. The two ends of the second buoyancy member 120 protrude from the first side wall 1111 and the second side wall 1112, respectively. The two ends of the third buoyancy member 130 protrude from the first side wall 1111 and the second side wall 1112, respectively. A first hollow 131 is formed between one end of the second buoyancy member 120 protruding from the first side wall 1111 and one end of the third buoyancy member 130 protruding from the first side wall 1111, and a second hollow 132 is formed between one end of the second buoyancy member 120 protruding from the second side wall 1112 and one end of the third buoyancy member 130 protruding from the second side wall 1112.

[0061] In other words, one end of the second buoyancy member 120 protrudes from the first sidewall 1111, and one end of the third buoyancy member 130 protrudes from the first sidewall 1111. Therefore, a hollow area is formed between one end (front end in the figure) of the second buoyancy member 120, one end (front end in the figure) of the third buoyancy member 130, and the main body 111, and is named a first hollow area 131. The other end of the second buoyancy member 120 protrudes from the second sidewall 1112, and the other end of the third buoyancy member 130 protrudes from the second sidewall 1112. Therefore, a hollow area is formed between the other end (rear end in the figure) of the second buoyancy member 120, the other end (rear end in the figure) of the third buoyancy member 130, and the main body 111, and is named a second hollow area 132.

[0062] In this embodiment, a first hollow 131 is formed between one end of the second buoyancy member 120, one end of the third buoyancy member 130, and the main body 111. A second hollow 132 is formed between the other end of the second buoyancy member 120, the other end of the third buoyancy member 130, and the main body 111. When the buoyancy device 10 is applied to the cleaning robot 1, when the cleaning robot 1 is placed on the water surface, the cleaning robot 1 will displace water in the area where it is located on the water surface to other locations through the first hollow 131 and the second hollow 132, thereby making the cleaning robot 1 more stable when placed on the water surface, reducing or even preventing the water displaced by the cleaning robot 1 from interfering with the stability of the cleaning robot 1 when placed on the water surface. It can be seen that the above design can make the cleaning robot 1 more stable in the water when placed on the water surface.

[0063] Furthermore, because the first sidewall 1111 and the second sidewall 1112 are opposite sides, the first hollow 131 and the second hollow 132 are arranged opposite each other. Therefore, when the buoyancy device 10 is applied to the cleaning robot 1 and the cleaning robot 1 is placed on the water surface, part of the water displaced by the cleaning robot 1 flows out of the first hollow 131, and the remaining part flows out of the second hollow 132. This allows for faster drainage, and the displaced water has little or no impact on the stability of the cleaning robot 1. This design ensures that the cleaning robot 1 maintains a relatively stable position in the water when placed on the water surface.

[0064] Further, referring to Figure 7, which is a rear view of the buoyancy device shown in Figure 6, in one embodiment, the length of the second buoyancy member 120 protruding from the first sidewall 1111 is less than the length of the second buoyancy member 120 protruding from the second sidewall 1112. The length of the third buoyancy member 130 protruding from the first sidewall 1111 is less than the length of the third buoyancy member 130 protruding from the second sidewall 1112.

[0065] Specifically, one end of the second buoyancy member 120 protrudes from the first sidewall 1111 by a first dimension d1, and the other end of the second buoyancy member 120 protrudes from the second sidewall 1112 by a second dimension d2, where d2>d1. One end of the third buoyancy member 130 protrudes from the first sidewall 1111 by a third dimension d3, and the other end of the third buoyancy member 130 protrudes from the second sidewall 1112 by a fourth dimension d4, where d4>d3.

[0066] Generally speaking, the weight of the main body 30 of the cleaning robot 1 may not be balanced at both ends. Generally speaking, one end of the main body 30 of the cleaning robot 1 is heavier and the other end of the main body 30 is lighter. For example, the electronic components (such as batteries, motors, etc.) of the main body 30 of the cleaning robot 1 are arranged at one end of the main body 30. Therefore, the end of the main body 30 where the electronic components are arranged is heavier, while the other end is lighter.

[0067] In this embodiment, in order to adapt to the weight conditions of each end of the body main body 30 of the cleaning robot 1 when the buoyancy device 10 is applied to the cleaning robot 1, d2>d1 and d4>d3. In this way, when the buoyancy device 10 is applied to the cleaning robot 1, it can provide greater buoyancy for the heavier end of the body main body 30, thereby ensuring that the cleaning robot 1 has a stable posture in the water.

[0068] Furthermore, in this embodiment, the shape of the first connecting portion 112 is compatible with the shape of the second buoyancy member 120, so that the first connecting portion 112 and the second buoyancy member 120 are more securely connected. Accordingly, the shape of the second connecting portion 113 is compatible with the shape of the third buoyancy member 130, so that the second connecting portion 113 and the third buoyancy member 130 are more securely connected. Specifically, one end of the first connecting portion 112 protrudes from the first sidewall 1111 by a dimension d1', and the other end of the first connecting portion 112 protrudes from the second sidewall 1112 by a dimension d2', where d2'>d1'. One end of the second connecting portion 113 protrudes from the first sidewall 1111 by a dimension d3', and the other end of the second connecting portion 113 protrudes from the second sidewall 1112 by a dimension d4', where d4'>d3'.

[0069] In one embodiment, d1 is equal to or approximately equal to d1', d2 is equal to or approximately equal to d2', d3 is equal to or approximately equal to d3', and d4 is equal to or approximately equal to d4'.

[0070] 2 , 4 , and 5 , in one embodiment, the buoyancy device 10 further includes a fitting portion 140 . The fitting portion 140 is protruding from the main body 111 and is located within the accommodating space 10 a . The fitting portion 140 is configured to support and fit the main body 30 of the cleaning robot 1 .

[0071] The fitting portion 140 is used to carry and fit the main body 30 of the cleaning robot 1. The shape of the fitting portion 140 can be, but is not limited to, a boss or a convex cone. The boss is provided on the main body 111 in a protruding manner, and the fitting portion 140 is located in the accommodating space 10a. On the one hand, when the main body 30 of the cleaning robot 1 is provided in the accommodating space 10a, the fitting portion 140 can better fit the main body 30 of the cleaning robot 1, thereby ensuring the stability of the buoyancy device 10 when carrying the main body 30; on the other hand, the fitting portion 140 can be regarded as a reinforcing rib of the main body, so that the buoyancy device 10 has better structural strength.

[0072] Furthermore, the buoyancy device 10 includes two spaced-apart fitting portions 140 , and a water channel 140 c is enclosed between the two fitting portions 140 and the main body 111 .

[0073] In this embodiment, the two fitting portions 140 are spaced apart along the first direction D1 , and the two fitting portions 140 and the main body 111 are enclosed to form the water guide groove 140 c .

[0074] The buoyancy device 10 includes two spaced-apart fitting portions 140 , and a water guide groove 140 c is enclosed between the two fitting portions 140 and the main body 111 , thereby guiding the water flow in a preset direction to speed up the water flow and improve the garbage cleaning efficiency of the cleaning robot 1 to which the buoyancy device 10 is applied.

[0075] In addition, when the buoyancy device 10 is applied to the cleaning robot 1, and when the cleaning robot 1 is placed on the water surface, the cleaning robot 1 will displace the position of the cleaning robot 1 on the water surface to other positions. The water guide groove 140c can ensure that the displaced water flows through, thereby reducing the resistance of the water flow, making the posture of the buoyancy device 10 more stable, and thus making the posture of the cleaning robot 1 to which the buoyancy device 10 is applied more stable.

[0076] Furthermore, referring to Figure 5 , one of the two fitting portions 140 is located near the second buoyancy member 120 and defines a first gap 140a between the fitting portion and the second buoyancy member 120. The other of the two fitting portions 140 is located near the third buoyancy member 130 and defines a second gap 140b between the fitting portion and the third buoyancy member 130. The first gap 140a and the second gap 140b are used to accommodate a portion of the structure of the main body 30.

[0077] One of the two fitting portions 140 is disposed adjacent to the second buoyancy member 120, and the other of the two fitting portions 140 is disposed adjacent to the third buoyancy member 130. A first gap 140a is formed between the fitting portion 140 adjacent to the second buoyancy member 120 and the second buoyancy member 120. A second gap 140b is formed between the fitting portion 140 adjacent to the third buoyancy member 130 and the third buoyancy member 130. For example, the first gap 140a and the second gap 140b are used to accommodate wheels of the main body 30.

[0078] One of the two fitting portions 140 is located near the second buoyancy member 120 and has a first gap 140a therebetween. The other of the two fitting portions 140 is located near the third buoyancy member 130 and has a second gap 140b therebetween. The first gap 140a and the second gap 140b are used to accommodate a portion of the main body 30, thereby fully utilizing the space within the buoyancy device 10 to accommodate the main body 30 and reducing the size of the cleaning robot 1 incorporating the buoyancy device 10.

[0079] In addition, in one embodiment, the first gap 140a between one of the two fitting parts 140 and the second buoyancy member 120 can not only accommodate part of the structure of the fuselage main body 30, but also one of the two fitting parts 140 and the second buoyancy member 120 are used to clamp and fix part of the structure of the fuselage main body 30, so that the fuselage main body 30 can be stably fixed to the buoyancy device 10.

[0080] In addition, the second gap 140b between the other of the two fitting parts 140 and the third buoyancy member 130 can not only accommodate part of the structure of the fuselage main body 30, but the other of the two fitting parts 140 and the third buoyancy member 130 are also used to clamp and fix part of the structure of the fuselage main body 30, so that the fuselage main body 30 can be stably fixed to the buoyancy device 10.

[0081] Please further refer to Figures 4 and 8. Figure 8 is a cross-sectional view of a buoyancy device provided in one embodiment of the present application. The buoyancy device 10 also includes a mounting portion 150 and a first magnetic member 160. The mounting portion 150 is disposed on the fitting portion 140. The first magnetic member 160 is supported on the mounting portion 150. The first magnetic member 160 is used to cooperate with the second magnetic member in the body 30 of the cleaning robot 1 to fix the body 30 of the cleaning robot 1.

[0082] The mounting portion 150 is used to mount the first magnetic member 160. In this embodiment, the mounting portion 150 is disposed on the fitting portion 140. In this embodiment, the mounting portion 150 is disposed on the end surface of the fitting portion 140 facing away from the main body. The mounting portion 150 may be, but is not limited to, a cylindrical protrusion or a prismatic protrusion. Accordingly, please refer to Figure 9, which is a back view of the main body of the cleaning robot in one embodiment of the present application. The main body 30 of the cleaning robot 1 has a mounting hole 311 for accommodating the mounting portion 150. When the mounting portion 150 is a cylindrical protrusion, the mounting hole 311 may be a circular hole; when the mounting hole 311 is a prismatic protrusion, the mounting hole 311 may be a prismatic hole. The mating arrangement of the mounting portion 150 of the buoyancy device 10 and the mounting hole 311 of the main body 30 allows the buoyancy device 10 to be fixed to the main body 30.

[0083] The first magnetic member 160 may be, but is not limited to, a magnet. Accordingly, the second magnetic member in the main body 30 of the cleaning robot 1 may be, but is not limited to, a magnet, or other components capable of being attracted by the first magnetic member 160 in the buoyancy device 10, or other components capable of attracting the first magnetic member 160 in the buoyancy device 10. This is not limited in this embodiment, as long as the first magnetic member 160 of the buoyancy device 10 and the second magnetic member in the main body 30 of the cleaning robot 1 cooperate to secure the main body 30 of the cleaning robot 1.

[0084] Optionally, in one embodiment, the first magnetic component 160 in the buoyancy device 10 is a magnet, and the second magnetic component of the fuselage main body 30 is a component that can be adsorbed by the first magnetic component 160 in the buoyancy device 10 (i.e., an adsorbed component); rather than the fuselage main body 30 being provided with a magnet, this can avoid adsorbing metal garbage that can be adsorbed on land, on the water surface, or underwater when a magnet is provided on the fuselage main body 30.

[0085] The first magnetic member 160 of the buoyancy device 10 is used to cooperate with the second magnetic member in the main body 30 of the cleaning robot 1 to secure the main body 30 of the cleaning robot 1, allowing the buoyancy device 10 to be detachably connected to the main body 30 of the cleaning robot 1. When the main body 30 of the cleaning robot 1 is used for surface cleaning, the first magnetic member 160 of the buoyancy device 10 is used to cooperate with the second magnetic member in the main body 30 of the cleaning robot 1 to secure the main body 30 of the cleaning robot 1. When the main body 30 of the cleaning robot 1 is used for underwater operations or land operations, the main body 30 can be removed from the buoyancy device 10 for underwater or land operations.

[0086] 8 , the mounting portion 150 is disposed on a side of the fitting portion 140 facing away from the main body 111 , and the mounting portion 150 is configured to be embedded in a mounting hole of the main body 30 of the cleaning robot 1 . The mounting portion 150 has a mounting groove 150 a , and the first magnetic member 160 is disposed in the mounting groove 150 a .

[0087] The mounting portion 150 is disposed on a side of the fitting portion 140 that is away from the main body 111. That is, from the perspective of the figure, the mounting portion 150 is disposed on the fitting portion 140. When the buoyant device 10 is used in a cleaning robot 1, the mounting portion 150 of the buoyant device 10 facilitates penetrating into the mounting hole 311 of the main body 30 of the cleaning robot 1.

[0088] In one embodiment, the first magnetic member 160 of the buoyancy device 10 is a magnet, and the second magnetic member of the main body 30 is a component that can be attracted by the first magnetic member 160 of the buoyancy device 10 (i.e., an attracted component). When the mounting portion 150 extends into the mounting hole 311 of the main body 30, the first magnetic member 160 of the buoyancy device 10 also enters the mounting hole 311 of the main body 30. The first magnetic member 160 of the buoyancy device 10 is enclosed in the relatively enclosed space of the mounting hole 311, thereby reducing or even preventing the first magnetic member 160 of the buoyancy device 10 from being exposed to the outside. This can further prevent the first magnetic member 160 from attracting attractable metal waste on land, on the surface of water, or underwater due to the exposure of the first magnetic member 160.

[0089] The distance from the mounting portion 150 to the second side wall 1112 is smaller than the distance from the mounting portion 150 to the first side wall 1111 .

[0090] The distance between the mounting portion 150 and the second side wall 1112 is smaller than the distance between the mounting portion 150 and the first side wall 1111 . Therefore, the mounting portion 150 is disposed at a relatively central position of the buoyancy device 10 , facilitating the cooperation between the buoyancy device 10 and the fuselage body 30 .

[0091] Continuing with FIG1 , the cleaning robot 1 provided in an embodiment of the present application includes a buoyancy device 10 and a main body 30 . The buoyancy device 10 can be described with reference to the previous description and will not be further described here. The main body 30 is accommodated within the accommodation space 10 a of the buoyancy device 10 .

[0092] The main body 30 is used for cleaning garbage. The main body 30 is housed within the accommodation space 10a of the buoyancy device 10. In one embodiment, the buoyancy device 10 is detachable from the main body 30. For example, in one embodiment, the buoyancy device 10 is detachably mounted on the bottom of the main body 30 of the cleaning machine.

[0093] When the cleaning robot 1 is used for water surface cleaning, the main body 30 is mounted on the buoyancy device 10 ; when the cleaning robot 1 is used for underwater cleaning, the buoyancy device 10 is removed from the main body 30 .

[0094] Please refer to Figure 10, which is a cross-sectional view of the fuselage main body provided in one embodiment of the present application. Furthermore, the fuselage main body 30 includes a motor box 30a, and the motor box 30a includes a shell 310 and electronic components. The electronic components are housed in the shell 310. When the fuselage main body 30 is housed in the accommodating space 10a of the buoyancy device 10, the electronic component motor box 30a is arranged corresponding to the first buoyancy member 110. In other words, the first buoyancy member 110 of the buoyancy device 10 is located at the position where the motor box 30a is located. Specifically, the orthographic projection of the electronic component motor box 30a in the fuselage main body 30 on the first buoyancy member 110 falls into the area where the first buoyancy member 110 is located. The electronic components of the motor box 30a may include, but are not limited to, a first motor 320 for driving the fuselage main body 30 to move and a second motor for driving a water pump. In other words, the motor box 30a may include, but is not limited to, a first motor 320 for driving the main body 30 and a second motor for driving a water pump. The water pump is typically mounted on the surface of the housing 310 of the motor box 30a. Furthermore, the electronic components of the motor box 30a may include components that require sealing and waterproofing, such as a printed circuit board (PCB) and a battery.

[0095] The weight of the main body 30 of the cleaning robot 1 may not be balanced at both ends. Generally speaking, one end of the main body 30 of the cleaning robot 1 is heavier, and the other end of the main body 30 is lighter. Generally speaking, the main body includes a motor box 30a, which is heavier and is arranged at one end of the main body 30. For example, the motor box 30a accounts for one-third of the weight of the entire main body 10. In one embodiment, the motor box 30a of the main body 30 of the cleaning robot 1 is arranged corresponding to the first buoyancy member 110, so that when the buoyancy device 10 is applied to the cleaning robot 1, the first buoyancy member 110 can provide greater buoyancy for the heavier motor box 30a of the main body 30, thereby ensuring that the cleaning robot 1 maintains a stable posture in the water.

[0096] In addition, in one embodiment, the cleaning robot 1 may further include a water surface cleaning trash basket 50. The water surface cleaning trash basket 50 may be disposed on the main body 30. The water surface cleaning trash basket 50 may be used to receive trash cleaned out by the main body 30.

[0097] In one embodiment, please refer to Figure 11, which is a circuit block diagram of a cleaning robot provided in one embodiment of the present application. The body body 30 of the cleaning robot 1 also includes an identification module 330. The identification module 330 is arranged near the shell 310 of the body body 30. When the water surface cleaning trash basket 50 is installed on the body body 30 (for example, the shell 310 of the body body 30), the identification module 330 outputs an installation success signal. In response to the installation success signal, the body body 30 (such as the cleaning device of the body body 30) can perform water surface cleaning.

[0098] In one embodiment, the water surface cleaning waste basket 50 includes a magnet 510, and the identification module 330 includes a Hall sensor 331. When the water surface cleaning waste basket 50 is installed on the main body 30, the Hall sensor 331 recognizes the magnet 510 and outputs an installation success signal. The cleaning robot 1 provided in this embodiment can intelligently identify whether the water surface cleaning waste basket 50 has been successfully installed. After the water surface cleaning waste basket 50 has been successfully installed, the main body 30 performs water surface cleaning, thereby reducing or even avoiding the situation where the main body 30 performs water surface cleaning without successfully installing the water surface cleaning waste basket 50, resulting in garbage not being collected in the water surface cleaning waste basket 50.

[0099] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.
