Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a robot. Background Art

[0002] With the continuous advancement of science and technology, the use of cleaning robots is becoming increasingly common, freeing hands and reducing labor costs for cleaning small, functional water areas such as swimming pools. Currently, cleaning robots can clean the pool bottom, walls, and surface, collecting dirt without draining the pool water. In other words, cleaning robots can sink to the bottom of the pool or float on the surface to clean.

[0003] To clean underwater, existing cleaning robots typically have interconnected suction and drainage ports on their housings. Specifically, when the robot is suspended on the water surface or sinks to the bottom of a pool to move through the water for cleaning, the robot can use the suction port to collect wastewater carrying dirt into a collection chamber within the housing for filtration and collection, and then discharge the clean water formed after decontamination into the pool through the drainage port, thereby cleaning the pool water, pool walls, and pool bottom. In addition, when the cleaning robot is taken out of the water, the water in the housing must be drained for maintenance.

[0004] However, the drainage efficiency of the shell of the existing cleaning robot is low, resulting in low replacement efficiency of sewage and clean water, and low cleaning and maintenance efficiency after water discharge, which affects the user experience. Utility Model Content

[0048] In the specification and claims of this utility model and the above-mentioned description of the drawings, when an element is referred to as being “fixed to”, “mounted on”, “disposed on” or “connected to” another element, it may be directly or indirectly located on the other element. For example, when an element is referred to as being “connected to” another element, it may be directly or indirectly connected to the other element.

[0049] Furthermore, references to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is 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.

[0050] The present invention provides a robot 100, which can be an aquatic cleaning robot capable of cleaning underwater and / or on the surface of water. Of course, the robot 100 can also be another suitable robot for other functions, such as a river inspection robot, and is not limited to operating only on water, as long as it can operate underwater and / or on the surface of a liquid.

[0051] It should be noted that the "liquid" mentioned herein may include water, other single liquids or mixed liquids, and is not particularly limited here. For ease of explanation, this article mainly describes the robot 100 that can clean on water.

[0052] like Figure 1 and Figure 2 As shown, the robot 100 includes an outer shell 1 and a functional component 2. The outer shell 1 is surrounded by an inner cavity 11, and a drain port 12 is provided on the outer wall of the outer shell 1. The inner cavity 11 is connected to the outside at multiple locations, and the drain port 12 is connected to both the outside and the inner cavity 11, so that the robot 100 as a whole can sink quickly underwater, and the water in the inner cavity 11 can be discharged as soon as possible after the robot 100 emerges from the water.

[0053] For example, Figure 1 and Figure 2 As shown, the housing 1 includes a bottom shell 14 and a cover shell 15. The cover shell 15 is mounted on the bottom shell 14 and together with the bottom shell 14, defines the aforementioned inner cavity 11. In this example, a drain port 12 is provided at the rear of the bottom shell 14 to facilitate faster drainage when the robot 100 is lifted out of the water. Of course, in other examples, the drain port 12 can be located elsewhere on the bottom shell 14 and / or cover shell 15, and this is not particularly limited here.

[0054] By way of further example, Figure 3 and Figure 5 As shown, the rear portion of the bottom shell 14 is provided with a plurality of drainage holes 121 communicating with the inner cavity 11, wherein the plurality of drainage holes 121 arranged side by side together form the aforementioned drainage port 12. Of course, in other examples, the drainage port 12 may also have other structures, such as a grid hole structure, a long strip hole structure, etc.

[0055] In addition, in this example, Figure 4 As shown, the bottom shell 14 of the housing 1 is further provided with a water baffle 144 at a position corresponding to the drain hole 121 to open or close the drain port 12. Optionally, within the inner cavity 11, one end of the water baffle 144 is rotatably connected to the shell wall of the bottom shell 14, and the other end is free. This allows the water baffle 144 to open the drain port 12 under the action of gravity when the robot 100 enters the water in the forward direction, or when the user lifts the robot 100 out of the water from the front end, and to close the drain port 12 under the action of gravity when the robot 100 enters the water in the reverse direction.

[0056] Of course, in other examples, the water retaining plate 144 may not be provided at the drainage hole 121, or the water retaining plate 144 may be provided at the drainage hole 121 using other existing or newly created structures, which is not particularly limited here.

[0057] In the embodiment of the present invention, the functional component 2 is disposed in the inner cavity 11 to assist in completing the operation of the robot 100. It should be noted that the functional component 2 of the robot 100 is not limited to being disposed in the inner cavity 11, but may also be disposed outside the inner cavity 11. This specification primarily focuses on the functional component 2 disposed in the inner cavity 11, and does not specifically limit the functional component outside the inner cavity 11.

[0058] In addition, the functional components 2 arranged in the inner cavity 11 include but are not limited to limiting ribs for limiting, sealing cavities 22 for sealing, collection frames 21 for collecting garbage, transmission mechanisms 3 for transmission, etc., which are not listed here one by one. Generally, parts and components that are accommodated in the inner cavity 11 and have functions can be called the above-mentioned functional components 2 arranged in the inner cavity 11.

[0059] In the embodiment of the present invention, at any transverse position in the direction of travel of the robot 100, at least one drainage gap is formed between the bottom and wall of the inner cavity 11, and / or between the bottom of the inner cavity 11 and the functional component 2, to form a continuous drainage channel 13 within the inner cavity 11 that flows toward the drain outlet 12. It is understood that in the direction of travel of the robot 100, there is no complete transverse structure on the bottom of the inner cavity 11, that is, there is no water flow interception point at the bottom of the cavity. Thus, when the amount of water in the inner cavity 11 is low, the water flow can flow directly from the front side of the robot 100 to the drain outlet 12 without being intercepted midway, which would result in low drainage efficiency and difficulty in draining the water from the inner cavity 11.

[0060] For example, Figure 2 、 Figure 3 and Figure 6 As shown, when both sides of a functional component 2 do not abut against the cavity wall, and there is only the functional component 2 at the cross-sectional position, two drainage gaps can be formed between the functional component 2 and the cavity bottom and cavity wall of the inner cavity 11. Figure 7 As shown, when one side of a functional component 2 abuts against the cavity wall and the other side does not, and there is only the functional component 2 at the cross-sectional position, a drainage gap can be formed between the functional component 2 and the bottom and wall of the inner cavity 11. Figure 7 As shown, when there are two functional components 2 at a certain transverse position and there is a gap between the two functional components 2 in the middle of the inner cavity 11, a drainage gap can be formed between the two functional components 2 and the bottom of the inner cavity 11.

[0061] It is also understandable that in different situations, the drainage path, the number of drainage gaps, etc. of the drainage channel 13 may be different. The specific drainage path may be determined according to the specific arrangement of the functional components 2 in the inner cavity 11. It is only necessary to ensure that the drainage channel 13 is continuously conductive, and the drainage path is not limited.

[0062] In summary, compared with the prior art, the robot 100 has at least the following beneficial effects:

[0063] The robot 100 reasonably arranges the functional components 2 in the inner cavity 11 to form at least one drainage gap between the bottom and the wall of the inner cavity 11, and / or between the bottom of the inner cavity 11 and the functional components 2 at any cross-sectional position of the robot 100, so that the drainage gaps at various locations are connected in the direction of travel of the robot 100, and form a continuous drainage channel 13 toward the drain port 12. When the robot 100 is lifted, the water in the inner cavity 11 can quickly flow directly to the drain port 12 for discharge, which is beneficial to draining the water in the inner cavity 11, improving drainage efficiency, and enhancing the user experience.

[0064] In order to make the technical personnel in this field better understand the present invention, the following Figures 1 to 11 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0065] In some embodiments of the present invention, Figures 2 to 8 As shown, in order to enable the robot 100 to have a collection function, the functional component 2 includes a collection frame 21. Correspondingly, a replacement port 141 communicating with the inner cavity 11 is opened at the bottom of the inner cavity 11 (see Figure 4 or Figure 8 The collecting frame 21 is detachably covered at the replacement port 141 in the inner cavity 11 so as to be connected with other parts such as the outside through the replacement port 141 to collect objects such as garbage.

[0066] Exemplarily, taking the robot 100 as a cleaning robot 100, the collection frame 21 can be used to collect garbage underwater or on the water surface as an example. The replacement port 141 is a water inlet opened at the bottom of the bottom shell 14, and the water inlet is connected to the outside and the inner cavity 11, wherein sewage can enter the inner cavity 11 from the water inlet. After the sewage is collected by the collection frame 21 to collect garbage, it is discharged into the inner cavity 11 through the collection frame 21 to become clean water. It can be understood that the continuously flowing drainage channel 13 formed in the inner cavity 11 of the robot 100 can help reduce the water resistance in the inner cavity 11, increase the water flow rate when the sewage and clean water are replaced, and thus help improve the cleaning efficiency.

[0067] In order to form a continuous drainage channel 13 at a corresponding transverse position, the collecting frame 21 forms at least one drainage gap in the inner cavity 11 and between the collecting frame 21 and the cavity wall or cavity bottom of the inner cavity 11 .

[0068] For example, in order to increase the size of the cavity of the collection frame 21 and improve the cleaning ability of the robot 100, the collection frame 21 generally has only one functional component 2 at its transverse position. Figure 2 、 Figure 3 、 Figure 6 and Figure 8 As shown, the collection frame 21 is disposed in the middle of the inner cavity 11 and forms a drainage gap with each of the two side walls of the inner cavity 11, namely two drainage gaps (referred to as first drainage gaps 131, corresponding to the water flows indicated by the red arrows in the figure). It is understood that when the robot 100 is lifted from the front, some of the water in the inner cavity 11 in front of the collection frame 21 can flow directly to the back of the collection frame 21 through the collection frame 21 or out of the water inlet, and some of the water can flow to the drain outlet 12 through the first drainage gaps 131 on both sides of the collection frame 21.

[0069] In some embodiments of the present invention, Figures 2 to 4 As shown, in order to enable the robot 100 to have the self-movement function and improve the waterproof function of the robot 100, the functional component 2 includes a first driving part 23. Correspondingly, at least one sealed cavity 22 is provided in the inner cavity 11, wherein the first driving part 23 can be used to drive the robot 100 to move by itself, and the first driving part 23 is built into the sealed cavity 22.

[0070] It should be noted that, in order to ensure the normal operation of the robot 100 on water, other functional components 2 are also built into the sealed cavity 22, not limited to the first drive unit 23. In addition, usually, when the robot 100 is working underwater or on the surface of the water, the sealed cavity 22 is immersed in water.

[0071] In order to form a continuous drainage channel 13 at the corresponding transverse position, at least one drainage gap is formed between each sealed cavity 22 and the cavity wall or cavity bottom of the inner cavity 11.

[0072] For example, Figures 2 to 4 、 Figure 9 As shown, a sealed cavity 22 is provided at the rear side of the collecting frame 21, wherein the sealed cavity 22 is provided in the middle of the inner cavity 11 and forms a drainage gap with each of the two side walls of the inner cavity 11, i.e., two drainage gaps (called second drainage gaps 132, corresponding to the water flow indicated by the green arrow in the figure). Figure 2 and Figure 3 As shown, when the robot 100 is lifted from the front, the water flowing out of the collecting frame 21 in the inner cavity 11 and the water flowing to the drain port 12 through the first drainage gap 131 can flow to the drain port 12 through the second drainage gap 132 .

[0073] In other examples, a plurality of sealed cavities 22 are provided at the rear side of the collecting frame 21, wherein when at least two sealed cavities 22 are arranged at intervals, a second drainage gap 132 can also be formed between two adjacent sealed cavities 22 and the bottom of the inner cavity 11. For example, Figure 7As shown, two sealing cavities 22 are provided, and the two sealing cavities 22 are arranged at intervals, and one of the sealing cavities 22 is in contact with the cavity wall of the inner cavity 11, and the other sealing cavity 22 is spaced apart from the cavity wall of the inner cavity 11. Then, a second drainage gap 132 is formed between the two adjacent sealing cavities 22 and the cavity bottom of the inner cavity 11, and a second drainage gap 132 is formed between the other sealing cavity 22 and the cavity wall of the inner cavity 11, that is, two drainage gaps are formed.

[0074] In some embodiments of the present invention, Figure 2 、 Figure 3 and Figure 9 As shown, in order to realize the cleaning function of the robot 100, the functional component 2 also includes a water pump 24 and a second drive unit 25, wherein the second drive unit 25 is built into the sealed cavity 22, the water pump 24 is in the inner cavity 11 and connected to the second drive unit 25, and the water pump 24 is connected to the outside through the top of the outer shell 1.

[0075] For example, a top drain hole 151 is formed on the top of the cover shell 15, communicating with the inner cavity 11 and the outside. The second driving unit 25 is built into the sealed cavity 22, and the output shaft of the second driving unit 25 is exposed outside the sealed cavity 22 and can be connected to a water pump 24 outside the sealed cavity 22. Optionally, the water pump 24 is typically provided at a position corresponding to the top drain hole 151.

[0076] It is understandable that when the inner cavity 11 is full or contains a large amount of water, for example, if the robot 100 is lifted from the front side, a portion of the water in the inner cavity 11 can be directly discharged from the robot 100 through the top drainage hole 151 of the cover shell 15, while a portion can be discharged through other holes and from the drain port 12 through the drainage channel 13. When the water in the inner cavity 11 is relatively small, the water in the inner cavity 11 can be discharged from the other holes of the outer shell 1 and from the drain port 12 through the drainage channel 13; when the water in the inner cavity 11 is very small, all the water in the inner cavity 11 can be directly discharged from the drain port 12 through the drainage channel 13. It can be seen that the water in the inner cavity 11 of the robot 100 has multiple ways to drain, ensuring that the water in the inner cavity 11 is completely drained more quickly, facilitating the subsequent maintenance and upkeep of the robot 100 and improving the user experience.

[0077] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, in order to enable the robot 100 to have the function of self-movement, the robot 100 also includes a driving paddle 4 and a transmission mechanism 3, wherein the driving paddle 4 can be used to drive the robot 100 to move on the water, and the transmission mechanism 3 is connected to the output end of the first driving part 23 in the sealed cavity 22, and is connected to the input end of the driving paddle 4, so as to drive the driving paddle 4 to rotate under the drive of the first driving part 23, thereby making the robot 100 move on the water as a whole.

[0078] In order to form a continuous drainage channel 13 at the corresponding transverse position, the transmission mechanism 3 forms at least one drainage gap between part of the inner cavity 11 and the sealing cavity 22, the cavity bottom and / or cavity wall of the inner cavity 11.

[0079] For example, Figure 2 、 Figure 10 and Figure 11 As shown, the transmission mechanism 3 includes a transmission gear 31. In the first drainage gap 131, the transmission gear 31 is sleeved on the output end of the first driving part 23 extending out of the sealed cavity 22, and is connected to the input end of the driving paddle 4 through other components. Among them, there is a gap between the side of the transmission gear 31 close to the bottom of the inner cavity 11 and the bottom of the inner cavity 11 to avoid interference with the bottom of the inner cavity 11; there is also a gap between the side of the transmission gear 31 close to the sealed cavity 22 and the sealed cavity 22 to avoid interference with the sealed cavity 22. Similarly, there is also a gap between the side of the transmission gear 31 close to the cavity wall of the inner cavity 11 and the cavity wall of the inner cavity 11 to avoid interference with the cavity wall of the inner cavity 11. In short, the transmission gear 31 and other components of the transmission mechanism 3 located in the inner cavity 11, the gaps formed in various places can together form a third drainage gap 133 (corresponding to the water flow indicated by the blue arrow in the figure).

[0080] It should be noted that the transmission gear 31 can adopt an existing structure or a novel structure to connect to the input end of the drive paddle 4, and this is not particularly limited here. Furthermore, the portion of the transmission mechanism 3 within the inner cavity 11 includes the transmission gear 31, but is not limited to the transmission gear 31 alone. Since the principle of forming the third drainage gap 133 is substantially the same, it will not be further described here.

[0081] Alternatively, as Figure 2 and Figure 3 As shown, when the sealing cavity 22 is located between the collecting frame 21 and the drain outlet 12, the drainage gap corresponding to the collecting frame 21 (specifically, the first drainage gap 131, corresponding to the water flow indicated by the red arrow in the figure), the drainage gap corresponding to the sealing cavity 22 (specifically, the second drainage gap 132, corresponding to the water flow indicated by the green arrow in the figure) and the drainage gap corresponding to the transmission mechanism 3 (specifically, the third drainage gap 133, corresponding to the water flow indicated by the blue arrow in the figure) are connected in sequence to form a drainage channel 13.

[0082] It can be understood that when the robot 100 is lifted out of the water, the water in the inner cavity 11 can flow in sequence along the first drainage gap 131, the second drainage gap 132, and the third drainage gap 133, and converge in the area between the sealed cavity 22 and the drain outlet 12 (corresponding to the water flow indicated by the pink arrow in the figure), and finally be discharged to the outside from the drain outlet 12.

[0083] It is also understandable that the sealed cavity 22 is arranged on the rear side of the robot 100. For example, by arranging the sealed cavity 22 on the rear side of the collection frame 21, the center of gravity of the robot 100 can be moved back to the center of the fuselage. In this way, the front side of the robot 100 can be tilted up to facilitate better movement of the robot 100 on the water surface and to facilitate the front side of the robot 100 to accommodate a larger collection frame 21.

[0084] Alternatively, Figure 2 and Figure 3 As shown, in the direction of travel of the robot 100, the collection frame 21 and the sealed cavity 22 are sequentially arranged in the middle part of the inner cavity 11, and a first drainage gap 131 is formed between the collection frame 21 and the side walls of the inner cavity 11, a second drainage gap 132 is formed between the sealed cavity 22 and the side walls of the inner cavity 11, and a third drainage gap 133 is formed between the transmission mechanism 3 and the side walls of the inner cavity 11 and the sealed cavity 22. The first drainage gap 131, the second drainage gap 132, and the third drainage gap 133 are connected to the drain port 12. In this way, on the one hand, the drainage path will not be too tortuous, and a shorter drainage channel 13 can be formed, which is conducive to draining the water in the inner cavity 11 more quickly. On the other hand, the reasonable layout of the functional components 2 in the inner cavity 11 facilitates the provision of a larger collection frame 21 and ensures the stability of the robot 100 as a whole when operating underwater or on the surface of the water.

[0085] In some embodiments of the present invention, Figure 1 、 Figure 4 and Figure 5 As shown, the outer shell 1 is also surrounded by an outer cavity 142, wherein the outer cavity 142 is through-connected from front to back and communicates with the outside, and the outer cavity 142 is separated from the inner cavity 11 in the upper and lower parts and communicates with each other in the outer shell 1. In addition, in order to realize that the robot 100 has a cleaning function, the robot 100 also includes a cleaning device 5, wherein the cleaning device 5 is arranged in the outer cavity 142, and is used to clean the surface to be cleaned or collect garbage when cleaning the water surface. It is understandable that because the cleaning device 5 needs to rotate and operate within the area limited by the outer cavity 142, rather than a larger area or even the entire water area, it can accelerate the flow of water in the outer cavity 142 to a certain extent, which is conducive to accelerating the replacement of sewage and clean water, thereby helping to improve cleaning efficiency.

[0086] Exemplarily, the outer cavity 142 and the inner cavity 11 are separated from each other by the bottom of the bottom shell 14, that is, the bottom of the inner cavity 11, and are connected by the displacement port 141 of the bottom shell 14. In addition, the driving paddle 4 that drives the robot 100 to move is also provided in the outer cavity 142. It is understandable that the sewage formed by the cleaning device 5 cleaning the surface to be cleaned can enter the inner cavity 11 through the displacement port 141, and the garbage in the sewage is collected by the collection frame 21, and the purified water is discharged through the collection frame 21. Obviously, compared with rotating within the range defined by the entire outer shell 1 or the entire water area, the driving paddle 4 and the cleaning device 5 located in the outer cavity 142 rotate within the area defined by the outer cavity 142, which can speed up the flow of sewage, allowing it to quickly pass through the displacement port 141 and enter the inner cavity 11, thereby accelerating the replacement of sewage and clean water, which is beneficial to improving cleaning efficiency and drainage efficiency.

[0087] In some embodiments of the present invention, Figures 3 to 7 As shown, to facilitate lifting the robot 100 from the front side of the housing 1, the housing 1 is provided with a handle 143 protruding from the inner cavity 11. The handle 143 is used for inserting a hand to hook up the robot 100. For example, the bottom shell 14 is provided with a handle 143 protruding from the bottom of the inner cavity 11. The handle 143 is located on the front side of the collection frame 21. When a hand is inserted into the handle 143 to hook and apply upward force, the robot 100 can be directly lifted.

[0088] Understandably, when the robot 100 is lifted from the water surface by hooking the handle 143, as shown in FIG. Figure 3 As shown, part of the water between the handle 143 in the inner cavity 11 and the collection frame 21 can enter the collection frame 21 (corresponding to Figure 3 、 Figure 4 The yellow arrow flows between the middle handle 143 and the collecting frame 21 and is discharged to the first drainage gap 131 (corresponding to the yellow arrow between the middle handle 143 and the collecting frame 21). Figure 3 or Figure 8 The yellow arrow in FIG2 flows from the collecting frame 21 to the first drainage gap 131), and / or is discharged to the rear side of the collecting frame 21 through the collecting frame 21 (corresponding to the yellow arrow in FIG22). Figure 3 The water between the inner collection frame 21 and the sealed cavity 22 is discharged as shown by the yellow arrow. Of course, it can also be discharged directly to the outside through the replacement port 141 corresponding to the collection frame 21; part of the water between the inner handle 143 of the inner cavity 11 and the collection frame 21 can also be directly converged into the first drainage gap 131 (corresponding to Figure 3 The two yellow arrow flows that merge into the red arrow flow are discharged.

[0089] Of course, after the water between the handle 143 and the collection frame 21 is drained, if there is still water in the first drainage gap 131, part of the water in the first drainage gap 131 can directly enter the second drainage gap 132, part of it can enter the collection frame 21 from the side and be directly discharged to the outside from the replacement port 141, and / or part of it can enter the collection frame 21 from the side and then be discharged from the side of the collection frame 21 close to the sealed cavity 22, and then converge into the second drainage gap 132.

[0090] It should be noted that the "handle 143" described here may adopt an existing structure or a newly created structure, and is not particularly limited here.

[0091] In addition, taking into account the amount of water in the inner cavity 11, the arrangement of various functional components, the angle at which the user lifts the robot 100, and other parts of the outer shell 1 that are connected to the outside, the specification and drawings of the present invention are marked with yellow, red, green, blue and pink arrows, only to better show the discharge of part of the water flow in the inner cavity 11; it does not rule out the discharge of water through other parts of the inner cavity 11 that are connected to the outside. In short, how the water in the inner cavity 11 is discharged to the outside is not specifically limited here and can be determined according to actual conditions. In order to more clearly describe the improvements of the present invention, the above description of the drainage path is only an example and cannot cover all situations.

[0092] In some embodiments of the present invention, the inner cavity bottom (not shown) of the inner cavity 11 is inclined toward the drain outlet 12, and when the robot 100 is placed upright, the front side of the inner cavity bottom of the inner cavity 11 is higher than the rear side, that is, the inner cavity bottom of the inner cavity 11 is inclined downward from the front side to the rear side of the robot 100. In this way, on the one hand, it is beneficial to reduce the water resistance in the inner cavity 11, increase the water flow rate in the inner cavity 11, and thus improve the cleaning efficiency. On the other hand, when the robot 100 is lifted, it is beneficial to further accelerate the discharge of water in the inner cavity 11 from the drainage channel 13. On the other hand, it is beneficial to provide a larger space for placing functional components 2 at the rear of the fuselage, which facilitates the reasonable layout of functional components 2 in the inner cavity 11.

[0093] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
