Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a cleaning robot and cleaning device. Background Technology

[0002] With the improvement of people's living standards and the development of technology, more and more cleaning devices capable of sweeping and mopping have appeared on the market. Cleaning devices include cleaning robots and bases. Cleaning robots usually use radar to sense the surrounding environment to determine whether they encounter obstacles, thereby achieving the effect of moving back and forth and cleaning within the target area.

[0003] The existing radar has a gap between itself and the inner wall of the mounting slot, making it easy for water to enter and accumulate. When the water level reaches a certain point, it can soak into the radar motor and circuit board inside the sensor module, causing short circuits and damage to the radar. Since the radar's mounting location is connected to the internal cavity of the cleaning robot, in severe cases, water can even enter the robot's cavity through gaps in the radar cover, corroding internal components and causing malfunctions or even failure. Summary of the Invention

[0004] Therefore, the present invention needs to provide a cleaning robot and cleaning device to avoid excessive water accumulation between the radar and the inner wall of the mounting slot, thereby ensuring the normal use of the radar and the cleaning robot.

[0005] A cleaning robot includes a shell, a detection module, a dust box mounting slot, and a flow guide channel. The top of the shell is provided with a mounting slot, which has an inclined bottom surface. The detection module is installed in the shell. The dust box mounting slot is installed outside the mounting slot. The higher end of the flow guide channel is connected to the lower side of the bottom surface, and the lower end of the flow guide channel is connected to the interior of the dust box mounting slot.

[0006] The aforementioned cleaning robot, by setting an inclined bottom surface on the mounting tank and using a guide channel to direct liquid from the mounting tank to the dust box mounting tank, allows the liquid entering the mounting tank to automatically drain out under its own weight, preventing water accumulation in the mounting tank and thus avoiding corrosion of the detection module. Furthermore, because the liquid in the mounting tank, guided by the guide channel, ultimately drains into the dust box mounting tank, it prevents corrosion of the cleaning robot's internal components, ensuring the normal operation of both the detection module and the cleaning robot.

[0007] In one embodiment, the guide channel includes a first channel and a second channel that are connected and arranged at an angle, the first channel being connected to the mounting slot and the second channel being connected to the dust box mounting slot.

[0008] In one embodiment, the angle α between the length direction of the first channel and the bottom surface is greater than the angle β between the length direction of the second channel and the bottom surface.

[0009] In one embodiment, the length direction of the first channel is approximately perpendicular to the bottom surface, and the length direction of the second channel is approximately horizontal to the bottom surface.

[0010] In one embodiment, the length direction of the first channel is perpendicular to the length direction of the second channel.

[0011] In one embodiment, the second channel has an inclined section at a point opposite to the first channel, and the lower side of the inclined section is connected to the dust box mounting groove.

[0012] In one embodiment, the mounting slot further includes a baffle, and the detection module includes a radar motor cavity disposed outside the baffle.

[0013] In one embodiment, the baffle is arranged around the bottom surface and has a first guide notch that communicates with the guide channel.

[0014] In one embodiment, the baffle further includes a second guide notch, the flow direction of which is consistent with the flow direction of the first guide notch and the flow channel.

[0015] A cleaning device includes a base and the aforementioned cleaning robot. The base has a housing space for accommodating the cleaning robot. The cleaning robot has a control unit and a cleaning unit, and the control unit controls the cleaning unit to complete the cleaning task.

[0016] The aforementioned cleaning device, by setting an inclined bottom surface on the mounting slot and using a guide channel, directs the liquid in the mounting slot to the dust box mounting slot. This allows the liquid entering the mounting slot to automatically drain out under its own weight, preventing water accumulation in the mounting slot and thus avoiding corrosion of the detection module. Furthermore, because the liquid in the mounting slot is ultimately guided to the dust box mounting slot by the guide channel, it prevents corrosion of the internal components of the cleaning robot, ensuring the normal operation of both the detection module and the cleaning robot.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] like Figures 1-3 As shown, this application provides a cleaning robot 10, including a housing 100, a detection module 200, a dustbin mounting slot 300, and a flow guide 400. The housing 100 has a mounting slot 110 on its top. The mounting slot 110 has an inclined bottom surface. The detection module 200 is installed in the housing 100. The dustbin mounting slot 300 is installed outside the mounting slot 110. The higher end of the flow guide 400 communicates with the lower side of the bottom surface. The lower end of the flow guide 400 communicates with the interior of the dustbin mounting slot 300.

[0028] Therefore, the cleaning robot 10 described above, by setting an inclined bottom surface on the mounting slot 110 and using the guide channel 400 to guide the liquid in the mounting slot 110 to the dust box mounting slot 300, allows the liquid entering the mounting slot 110 to automatically pass through the guide channel 400 and be discharged under its own gravity. This helps to prevent water accumulation in the mounting slot 110, thereby avoiding corrosion of the detection module 200. Furthermore, since the liquid in the mounting slot 110, guided by the guide channel 400, will eventually drain into the dust box mounting slot 300, it can prevent the liquid from corroding the internal components of the cleaning robot 10, thus ensuring the normal operation of both the detection module 200 and the cleaning robot 10.

[0029] It should be noted that the sensing module in the radar component of this application is a lidar. In other embodiments, the sensing module may also be a camera module or other sensor modules.

[0030] In addition, the detection module 200 is also provided with a protective shell (not shown in the figure) to protect the electronic components in the detection module 200. The protective shell can be integrally molded with the housing 100 using an injection molding process, or they can be molded separately and then assembled into a single unit. Specifically, in this embodiment, the protective shell and the housing 100 are configured to be molded separately and then assembled into a single unit.

[0031] It should also be noted that the dust box mounting groove 300 in this application should be a waterproof dust box mounting groove 300, that is, capable of collecting and storing the introduced liquid to prevent the liquid from corroding the electronic components inside the cleaning robot 10.

[0032] Understandably, the detection module 200 can be a radar device, or a camera, acoustic detector, or other device capable of detecting the surrounding environment and requiring protection against water corrosion of circuit boards. Specifically, in this application, the detection module 200 is a radar detection device.

[0033] like Figures 4-5 As shown, in one embodiment, the flow guide trough 400 includes a first channel 410 and a second channel 420 that are connected and arranged at an angle. One end of the first channel 410 opposite to the second channel 420 is connected to the mounting groove 110. The other end of the second channel 420 opposite to the first channel 410 is connected to the dust box mounting groove 300. Therefore, liquid inside the mounting groove 110 can flow sequentially through the first channel 410 and the second channel 420, thereby entering the dust box mounting groove 300.

[0034] It should be noted that the first channel 410 and the second channel 420 are set at an angle, which can be understood as the length direction of the first channel 410 forming an angle with the length direction of the second channel 420. Therefore, when liquid flows through the first channel 410 into the second channel 420, the inner wall of the second channel 420 will create a certain obstruction for the liquid, reducing the flow velocity of the liquid when it enters the dust box mounting slot 300. This prevents the liquid from flowing too fast into the dust box mounting slot 300, which would cause excessively violent impacts on the liquid already collected in the dust box mounting slot 300, resulting in liquid splashing, abnormal noises, etc. This helps to improve the stability of the flow in the liquid guide channel 400 during the process of guiding the liquid to the dust box mounting slot 300.

[0035] Furthermore, in one embodiment, the angle α between the length direction of the first channel 410 and the bottom surface is greater than the angle β between the length direction of the second channel 420 and the bottom surface. It should be noted that although the bottom surface is inclined, the angle of inclination is relatively small. Therefore, when comparing angles α and β, it can be considered that the angle between the length direction of the first channel 410 and the horizontal plane is approximately equal to angle α; similarly, the angle between the length direction of the second channel 420 and the horizontal plane is also approximately equal to angle α.

[0036] Therefore, the liquid in the mounting tank 110 can flow quickly to the bottom surface of the mounting tank 110 in the steeper first channel 410, reducing the time it takes for the liquid to leave the mounting tank 110 and preventing water accumulation. Furthermore, compared to a gentler surface, the steeper first channel 410 prevents liquid from being guided out of the mounting tank 110 during the movement of the cleaning robot 10. During movement, the liquid flows back into the mounting tank 110 through the first channel 410, further enhancing the guiding effect of the guide channel 400 on the liquid in the mounting tank 110, preventing corrosion of the detection module 200, and ensuring the normal operation of the detection module 200.

[0037] In addition, the gentler second channel 420 can slow down the flow rate of the liquid flowing out of the first channel 410, so that the flow rate of the liquid entering the dust box mounting slot 300 is reduced, and the liquid entering the dust box mounting slot 300 afterward will not cause too violent impact on the liquid already collected in the dust box mounting slot 300, causing liquid splashing, abnormal noise, etc. in the dust box mounting slot 300.

[0038] Specifically, in this embodiment, the angle between the length direction of the first channel 410 and the bottom surface is approximately perpendicular. The angle α between the length direction of the first channel 410 and the bottom surface ranges from 70° to 90°. The angle between the length direction of the second channel 420 and the bottom surface is approximately parallel. The angle β between the second channel 420 and the bottom surface ranges from 0°.

[0039] The angle is between ~20°. The length direction of the first channel 410 is perpendicular to the length direction of the second channel 420. This allows water in the mounting groove 110 to leave the bottom surface of the mounting groove 110 and enter the first channel 410 in a roughly "free-fall" manner. The liquid in the first channel 410 can vertically impact the inner wall of the second channel 420 and then gently enter the dust box mounting groove 300 at a relatively slow rate.

[0040] Furthermore, such as Figure 5 As shown, the second channel 420 has an inclined portion 421 at a section opposite to the first channel 410. The lower side of the inclined portion 421 is connected to the dust box mounting groove 300. Therefore, the inclined portion 421 can not only guide the liquid in the second channel 420 to flow into the dust box mounting groove 300, but also increase the size of the outlet of the second channel 420 (i.e., the connection between the second channel 420 and the dust box mounting groove 300), facilitating the flow of liquid into the interior of the dust box mounting groove 300.

[0041] like Figure 3 As shown, in one embodiment, the mounting groove 110 further includes a baffle 120. The detection module 200 includes a radar motor cavity 210. The radar motor cavity 210 is located outside the baffle 120. The baffle 120 forms a "fence" structure on the bottom surface of the mounting groove 110 to prevent liquid from entering the radar motor cavity 210. When too much liquid enters the mounting groove 110 and does not have time to flow into the dust box mounting groove 300 through the guide groove, the baffle 120 can form a small "reservoir" with the bottom surface to prevent liquid from directly entering the radar motor cavity 210 and avoid liquid corrosion of the components inside the radar motor cavity 210.

[0042] Furthermore, the baffle 120 is arranged around the bottom surface and has a first guide notch 121. The first guide notch 121 communicates with the guide channel 400. Therefore, liquid in the area of ​​the bottom surface surrounded by the baffle 120 can flow into the guide channel 400 through the first guide notch 121. It should be noted that the first guide notch 121 is located on the lower side of the bottom surface, specifically, on the lowest side of the bottom surface, thereby preventing excessive water accumulation near the baffle 120.

[0043] like Figure 3As shown, in one embodiment, the baffle 120 further includes a second guide notch 122. The flow direction of the second guide notch 122 is consistent with the flow direction of the first guide notch 121 and the flow channel 400.

[0044] It should be noted that, from a top-down view, the flow directions of the second guide notch 122, the first guide notch 121, and the guide direction of the guide channel 400 are all on the same straight line. This arrangement shortens the path of the liquid into the guide channel, increases the rate at which the liquid enters the guide channel, and prevents excessive water accumulation in the installation tank 110. When liquid enters the installation tank 110, it first passes through the second guide notch 122 into the "reservoir" formed by the baffle 120 and the bottom surface, and then, guided by the inclined bottom surface, passes through the first guide notch 121 and enters the guide channel.

[0045] This application also provides a cleaning device (not shown), including a base (not shown) and the aforementioned cleaning robot 10. The base has an accommodating space for accommodating the cleaning robot 10. The cleaning robot 10 also includes a control unit (not shown) and a cleaning unit (not shown). The control unit controls the cleaning unit to complete the cleaning task.
