Technical Field
[0001] This application relates to the field of intelligent cleaning technology, and in particular to a cleaning robot. Background Technology
[0002] In the field of intelligent cleaning technology, cleaning robots include a clean water tank and a wastewater tank. The clean water tank stores clean water used for cleaning the floor, while the wastewater tank collects the wastewater generated during the floor cleaning process.
[0003] In existing technologies, the arrangement of clean water tanks and wastewater tanks is usually either vertical, with the wastewater tank on top and the clean water tank below, or front-to-back, with the wastewater tank in front and the clean water tank behind. These two arrangements cannot effectively utilize stacking space, resulting in relatively small volumes for both the clean water and wastewater tanks. Furthermore, as the cleaning robot operates, the clean water in the tank gradually decreases, while the wastewater in the tank gradually increases, which can easily cause a shift in the center of gravity, making the cleaning robot unstable during operation.
[0004] In addition, cleaning robots typically lay silicone pads flat at the openings above the clean water tank and waste water tank, which is not very effective at preventing leaks and cannot prevent water from the clean water tank and waste water tank from flowing into the electrical components below the tank. Utility Model Content
[0005] The purpose of this application is to provide a cleaning robot that increases the water tank volume while maintaining the same overall size, making the robot more stable during operation and improving the leak-proof performance of the water tank assembly. The specific technical solution is as follows:

[0039] 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, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.
[0040] As mentioned in the background section, in existing technologies, the arrangement of clean water tanks and wastewater tanks is typically either top-to-bottom, with the wastewater tank on top and the clean water tank below, or front-to-back, with the wastewater tank in front and the clean water tank behind. These two arrangements fail to effectively utilize stacking space, resulting in small volumes for the clean water and wastewater tanks. Furthermore, as the cleaning robot operates, the clean water in the tank gradually decreases, while the wastewater in the tank gradually increases, easily causing a shift in the center of gravity and making the cleaning robot unstable during operation. In addition, the cleaning robot usually places silicone pads flat at the openings above the clean water and wastewater tanks, which provides poor leak prevention and cannot prevent water from the clean water and wastewater tanks from flowing into the electrical components below the tanks.
[0041] In view of this, the present application provides a cleaning robot that increases the water tank volume without changing the overall size of the robot, makes the cleaning robot run more stably during operation, and improves the water tank assembly's leak-proof effect.
[0042] like Figures 1 to 4 As shown, the cleaning robot includes: a vehicle body 10, a water tank assembly 20, and a cleaning assembly 30. The water tank assembly 20 is fixed to the top of the vehicle body 10; the cleaning assembly 30 is located at the bottom of the vehicle body 10. The water tank assembly 20 includes: a clean water tank 100, a wastewater tank 200, and a water collection box 300. The clean water tank 100, the wastewater tank 200, and the water collection box 300 can all be fixed to the mounting bracket 11 on the top of the vehicle body 10 by threaded fasteners.
[0043] The clean water tank 100 is an annular tank. A through-walled receiving space 120 is formed within the inner ring wall 110 of the clean water tank 100. The wastewater tank 200 is disposed within the receiving space 120. A water receiving box 300 is disposed at the bottom of both the clean water tank 100 and the wastewater tank 200, with its opening facing upwards, to collect water overflowing from the wastewater tank 200 and / or the clean water tank 100.
[0044] The cleaning robot provided in this application embodiment places the wastewater tank 200 within the accommodating space 120 of the inner ring wall 110 of the clean water tank 100, which saves stacking space and increases the tank volume without changing the overall size of the robot. For example, when the clean water tank and wastewater tank are arranged vertically without changing the overall size of the robot, the clean water tank volume is 35L and the wastewater tank volume is 25L; while in this application embodiment, the clean water tank 100 and wastewater tank 200 are arranged in the above-mentioned nested configuration, resulting in a clean water tank volume of 45L and a wastewater tank volume of 35L.
[0045] Because the clean water tank 100 and the wastewater tank 200 are nested as described above, as the cleaning robot operates, the center of gravity of the entire clean water tank 100 and wastewater tank 200 shifts from... Figure 5As shown, O1 gradually moves to O2 and then O3. The overall center of gravity does not shift left or right due to the continuous decrease of clean water in the clean water tank 100 and the continuous increase of sewage in the sewage tank 200, making the cleaning robot operate more stably. The aforementioned left or right shift refers to... Figure 4 The offset in the x-direction is shown. The x-direction is the horizontal direction perpendicular to the forward direction y of the vehicle body 10. O1 is the overall center of gravity position when the clean water tank 100 is full, O2 is the overall center of gravity position when the clean water tank 100 is half full of clean water and the wastewater tank 200 is half full of wastewater, and O3 is the overall center of gravity position when the wastewater tank 200 is full.
[0046] A water receiving box 300 is installed at the bottom of the clean water tank 100 and the wastewater tank 200 to collect water overflowing from the clean water tank 100 and / or the wastewater tank 200. This prevents the overflowing water from flowing into the electrical components 40 below the tank, thus improving the leak-proof effect.
[0047] Specifically, such as Figure 1 As shown, the aforementioned electrical component 40 is installed inside the vehicle body 10. The electrical component 40 includes: a controller, and a water pump, an air extraction device, a travel drive motor, and a cleaning component drive motor electrically connected to the controller. Under the control of the controller, the water pump delivers clean water from the clean water tank 100 to the cleaning component 30 through pressure; the air extraction device can extract air from the sewage tank 200 to the outside of the sewage tank 200, allowing sewage on the ground to enter the sewage tank 200 through the suction pipe 250 for sewage collection; the travel drive motor can drive the vehicle body 10 to move; and the cleaning component drive motor can drive the cleaning component 30 to clean the ground.
[0048] like Figure 2 As shown, the body of the clean water tank 100 serves as the exterior surface of the water tank assembly 20, eliminating the need for additional exterior coverings. This saves costs and simplifies the structure of the water tank assembly 20. In the limited installation space of the water tank assembly, the space occupied by the exterior coverings is saved, allowing the clean water tank 100 and / or the wastewater tank 200 to be set larger, thereby further increasing the water tank volume.
[0049] A handle 190 is provided on the outer ring wall 150 of the clean water tank 100 to facilitate the user to take out and put in the water tank assembly 20.
[0050] like Figure 3 As shown, a water inlet 160 is provided on the outer ring wall 150 of the clean water tank 100. An automatic drain outlet 171 and a manual drain outlet 172 are provided at the bottom of the clean water tank 100. The automatic drain outlet 171 is connected to the cleaning assembly 30 to provide the cleaning assembly 30 with the clean water required for floor cleaning.
[0051] like Figure 1As shown, a drain pipe 180 is inserted into the manual drain port 172, with the bottom end of the drain pipe 180 extending to the bottom of the vehicle body 10. In actual use, the user can place the bottom end of the drain pipe 180 in the discharge area and drain the remaining clean water in the clean water tank 100 through the manual drain port 172. When manual drainage is not required, the drain pipe 180 can be attached to the vehicle body 10 using a fixing clip.
[0052] In this embodiment of the application, the water inlet 160 is positioned on the outer ring wall 150 of the clean water tank 100, preventing interference with the wastewater tank 200 and the vehicle body 10, thus facilitating the addition of water to the clean water tank 100. The two drain outlets on the clean water tank 100 allow for both automatic and manual drainage, making it more flexible and convenient to use. Positioning the two drain outlets at the bottom of the clean water tank 100, closer to the bottom of the vehicle body 10, shortens the pipe length between the automatic drain outlet 171 and the cleaning assembly 30, as well as the length of the drain pipe 180, resulting in a more rational pipe layout and a more compact internal structure within the vehicle body 10.
[0053] The clean water tank 100 can be configured with a detachable connection between the clean water tank body and the clean water tank lid, or it can be configured as follows: Figure 3 The integrated structure shown creates a sealed space inside the clean water tank 100 when the water inlet 160, automatic drain outlet 171, and manual drain outlet 172 are all closed. This eliminates the need for a separate tank cover, simplifying the structure of the clean water tank 100 and reducing areas prone to leakage, thus improving safety. This application will be further elaborated upon below. Figure 3 The structure of the clear water tank 100 shown is used as an example for explanation.
[0054] like Figure 8 As shown, the bottom of the sewage tank 200 is equipped with an air intake 230 and a sewage suction port 240. The air intake 230 is connected to an air extraction device installed inside the vehicle body 10. Figure 1 As shown, a suction pipe 250 is inserted into the suction port 240, and the bottom end of the suction pipe 250 extends to the bottom of the vehicle body 10.
[0055] like Figure 6 As shown, the water tank assembly 20 includes a cover 600. The cover 600 covers the top of the clean water tank 100 and the wastewater tank 200, and abuts against the edge of the top opening of the wastewater tank 200, so that the interior of the wastewater tank 200 forms a sealed space, so that the vacuum device can evacuate the wastewater tank 200, and the ground wastewater can be transported to the wastewater tank 200 along the suction pipe 250.
[0056] To prevent sewage from entering the suction pipe of the sewage tank 200 when the suction device is working, the suction pipe can be extended into the sewage tank 200 from the suction port 230, and the top of the suction pipe can be extended upward to a position close to the cover 600, which improves safety.
[0057] like Figure 7 As shown, a foam mounting platform 270 is provided on the inner side of the sewage tank 200 near the cover 600. The foam mounting platform 270 is used to fix foam. A through hole 271 is provided on the foam mounting platform 270, and the top of the suction pipe extends to the through hole 271. The foam covers the top of the suction pipe, which on the one hand seals the opening at the top of the suction pipe to prevent air leakage and improve the working efficiency of the suction device, allowing for more efficient suction of sewage into the sewage tank 200; on the other hand, it intercepts foreign objects and impurities, preventing them from entering the suction pipe and further improving safety.
[0058] In some embodiments of this application, such as Figure 8 As shown, a drain outlet 260 is provided at the bottom of the sewage tank 200. A drain pipe is inserted into the drain outlet 260, and the bottom end of the drain pipe extends to the bottom of the vehicle body 10.
[0059] Electrical component 40 includes a liquid level detection device. When the liquid level detection device detects that the sewage in the sewage tank 200 has reached a certain height, the controller can control the valve on the drain pipe to open, allowing the sewage to be discharged along the drain pipe. In other embodiments of this application, the drain pipe can also be a manual drain type, allowing the user to manually discharge the sewage.
[0060] like Figure 9 As shown, the air intake 230, the sewage intake 240, and the sewage discharge 260 are all located at the bottom of the sewage tank 200, and the pipes connected to them can extend directly downwards, which can avoid interference with the clean water tank 100, making the structure of the water tank assembly 20 more compact and the layout of the pipes connected to the water tank assembly 20 more reasonable.
[0061] In some embodiments of this application, such as Figure 6 As shown, there is a gap 130 between the wall of the wastewater tank 200 and the inner wall 110 of the clean water tank 100. The projection of the opening of the water receiving box 300 onto the bottom of the clean water tank 100 and the wastewater tank 200 at least covers the bottom of the gap 130. Water overflowing from the clean water tank 100 and / or the wastewater tank 200 will flow down the side walls of the gap 130 and fall into the water receiving box 300.
[0062] The specific structure of the water box 300 in this application is not limited, as long as its projection can cover the bottom of the gap 130. In one embodiment, such as Figure 10 As shown, the water receiving box 300 is ring-shaped. While ensuring its water receiving capacity, the volume of the water receiving box 300 is reduced, allowing more space at the bottom of the clean water tank 100 and the sewage tank 200 to arrange pipes, thus improving space utilization.
[0063] In some embodiments of this application, such as Figure 3As shown, the bottom of the clean water tank 100 is provided with a first receiving groove 140 with its opening facing downwards, and the first receiving groove 140 surrounds the inner ring wall 110 of the clean water tank 100. Figure 8 As shown, the bottom of the sewage tank 200 is provided with a second receiving groove 210 with its opening facing downwards, and the second receiving groove 210 surrounds the bottom of the sewage tank 200.
[0064] like Figure 11 As shown, the outer ring sidewall 310 of the water receiving box 300 is inserted into the first receiving groove 140, and the inner ring sidewall 320 of the water receiving box 300 is inserted into the second receiving groove 210.
[0065] By employing the embodiments of this application, the sidewall of the water receiving box 300 is accommodated by creating grooves at the bottom of the clean water tank 100 and the wastewater tank 200. Compared to placing the water receiving box 300 directly at the bottom of the clean water tank 100 and the wastewater tank 200, this improves space utilization, shortens the longitudinal dimension of the water tank assembly 20, and makes the bottom of the water tank assembly 20 flat, facilitating its fixation to the vehicle body 10. The sidewall of the water receiving box 300 also provides lateral restraint for the clean water tank 100 and the wastewater tank 200, eliminating the need for additional lateral restraint components and simplifying the structure of the water tank assembly 20.
[0066] In some embodiments of this application, such as Figure 10 As shown, a drain hole 330 is provided at the bottom of the water receiving box 300. Figure 12 As shown, the cleaning robot includes a drain pipe 400. One end of the drain pipe 400 is connected to a drain hole 330, and the other end is connected to the cleaning assembly 30.
[0067] Using the embodiments of this application, water in the water receiving box 300 can flow along the drain pipe 400 to the cleaning component 30 for floor cleaning, which can save water and effectively reduce the risk of overflowing water dripping directly onto the electrical component 40 and causing damage to the device.
[0068] The number of drainage holes 330 is not limited in this application; there may be one or more.
[0069] In some embodiments of this application, the number of drainage holes 330 is multiple. For example... Figure 12 As shown, the drain pipe 400 includes: a branch drain pipe 410 and a main drain pipe 420.
[0070] Each drain hole 330 is connected to a branch drain pipe 410, and each branch drain pipe 410 is connected to the main drain pipe 420 through a pipe connector 430. The main drain pipe 420 is connected to the cleaning assembly 30.
[0071] Compared to directly connecting multiple branch drain pipes 410 to the cleaning assembly 30, this application uses a main drain pipe 420 to collect the water from each branch drain pipe 410 before connecting it to the cleaning assembly 30, which simplifies the connection between the water collection box 300 and the cleaning assembly 30 and also increases the water output.
[0072] The arrangement of the aforementioned multiple drainage holes 330 is not limited in this application, but is preferably evenly distributed around the circumference of the water receiving box 300, so that the water in the water receiving box 300 can flow more evenly and efficiently into each branch drainage pipe 410. For example Figure 10 As shown, there are 3 drainage holes 330, which are evenly distributed around the circumference of the water box 300.
[0073] In some embodiments of this application, such as Figure 13 As shown, the inner wall 110 of the clean water tank 100 has a first mounting boss 111 protruding towards the receiving space 120. The wall of the wastewater tank 200 has a second mounting boss 220 protruding outward. The bottom surface of the second mounting boss 220 abuts against the top surface of the first mounting boss 111.
[0074] By applying the embodiments of this application, the sewage tank 200 is installed and limited by setting the first mounting boss 111 and the second mounting boss 220, without the need for additional fasteners, which simplifies the structure of the water tank assembly 20; and the platforms of the first mounting boss 111 and the second mounting boss 220 abut against each other, with a large and flat contact surface, which reduces the relative shaking between the sewage tank 200 and the clean water tank 100, making the center of gravity of the water tank assembly 20 more stable during the movement of the vehicle body 10.
[0075] In some embodiments of this application, such as Figure 13 As shown, the water tank assembly 20 also includes a shock-absorbing pad 500. The shock-absorbing pad 500 is disposed between the first mounting boss 111 and the second mounting boss 220, which can effectively reduce the surface friction between the sewage tank 200 and the clean water tank 100 during the movement of the vehicle body 10, reduce the risk of wear and damage to the surfaces of the two mounting bosses, and reduce the amount of shaking of the sewage tank 200 during the movement of the vehicle body 10. The shock-absorbing effect is optimal when the hardness of the shock-absorbing pad 500 is 30° and the interference is 30%.
[0076] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
