[0046] To make the objectives, features, and advantages of this application more readily apparent, the present application is further described below in conjunction with the accompanying drawings and specific embodiments. It is apparent that the embodiments described are only a portion of the embodiments of this application, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments in this application without inventive effort are also within the scope of protection of this application.

[0047] After analyzing existing technologies, the inventors discovered that existing robot vacuums require users to remove the main unit and refill the water tank, or they can install the tank internally and automatically refill the water via the base station. This approach doesn't work both ways. Furthermore, the sealing connection of the water channel adapter requires numerous and complex parts, hindering assembly and increasing manufacturing costs.

[0048] The main technical problem solved by the present invention is how to enable manual water addition and automatic water addition to coexist, and how to prevent water in the water tank from leaking during manual water addition.

[0049] To solve the above technical problems, the present invention adopts a technical solution: a water tank is used for manual and automatic water addition of the cleaning robot. The water tank consists of a tank body and a water pipe connector assembly. A water-adding silicone plug is provided at the top of the water tank. When the user manually adds water, the water is filled inside the water tank and then the plug is closed. There are three ports on the bottom of the water tank that are connected to the water pipe connector assembly. Figure 2 This is the assembled state of the water tank. The water pipe connector is fixed inside the main body of the sweeping robot and cannot be disassembled. The water tank is fixed by two movable bayonet and is a detachable separate module.

[0050] The present application can realize both manual and automatic water adding modes for the cleaning robot, and can achieve good sealing effect when the water tank is lifted out, and the residual water will not penetrate; the water in the water tank can be fully utilized with high utilization rate, and the water tank has anti-explosion function.

[0051] Reference Figure 1, shows a structural schematic diagram of the water tank of the cleaning robot of the present invention, which may specifically include the following structure: the water tank is connected to the robot body through a water pipe connector 2, and includes a box body 1; the box body 1 is communicated with the water pipe connector 2; a water filling port 11 is provided on the top of the box body 1; a first valve plug 5 is provided at the bottom of the box body 1; the water pipe connector 2 is provided with a water injection connection port 21, and the water injection connection port 21 is adapted to the first valve plug 5; the box body 1 is separated from the water pipe connector 2, the first valve plug 5 is reset, and the first valve plug 5 blocks the bottom of the box body 1; the box body 1 is connected to the water pipe connector 2, the water injection connection port 21 pushes the first valve plug 5 to move upward, and the first valve plug 5 is communicated with the water injection connection port 21.

[0052] In the embodiments of the present application, compared with the prior art in which "manual water addition and automatic water addition cannot be achieved at the same time", the present application provides a design that achieves both manual water addition and automatic water addition through the setting of a box body 1 and a water pipe connector 2. Specifically, the water tank is connected to the robot body through a water pipe connector 2 set on the robot body, including a box body 1; the box body 1 is connected to the water pipe connector 2; a water filling port 11 is provided on the top of the box body 1; a first valve plug 5 is provided at the bottom of the box body 1; the water pipe connector 2 is provided with a water injection connection port 21, and the water injection connection port 21 is adapted to the first valve plug 5; the box body 1 is separated from the water pipe connector 2, the first valve plug 5 is reset, and the first valve plug 5 blocks the bottom of the box body 1; the box body 1 is connected to the water pipe connector 2, and the water injection connection port 21 pushes the first valve plug 5 to move upward, and the first valve plug 5 is connected to the water injection connection port 21. The present application can realize both manual water adding and automatic water adding. The user can take out the water tank to add water, and the robot can also automatically replenish water after returning to the base station; and when the user takes out the water tank from the host, if there is residual water stains in the water tank, the design of the valve plug of the present application prevents the residual water stains from leaking onto the user or the ground; when the water outlet level of the water tank is lower than the bottom of the water tank, the water can be drained for sweeping and mopping the ground; when automatically filling with water, the present application has a mechanical anti-explosion function. When the water flow reaches the top of the water tank, the water flows back to avoid the hidden dangers caused by water in the circuit.

[0053] Furthermore, the water pipe connector 2 can be installed at the bottom of the water tank according to actual needs, forming an integrated design with the water tank. The water pipe connector 2 can also be used as a separate component. When automatic water addition is required through the base station, the user can assemble it at the bottom of the water tank or the robot body to achieve automatic water addition.

[0054] Next, a water tank for a cleaning robot in this exemplary embodiment will be further described.

[0055] In this embodiment of the present application, the top of the housing 1 is provided with a water inlet 11; the water inlet 11 is provided with a sealing cover 3; the sealing cover 3 is adapted to fit within the water inlet 11; and a water-adding silicone plug is provided at the connection between the sealing cover 3 and the water inlet 11. A sealing spring 31 is provided between the sealing cover 3 and the housing 1.

[0056] As an example, the sealing cover 3 is detachably connected to the tank body 1. The sealing cover 3 is preferably oval, but may also be round, square, or other shapes, without limitation. One end of the sealing cover 3 can be rotated to open, and the other end of the bottom of the sealing cover 3 can be connected to the water tank via a sealing spring 31; the sealing spring 31 acts as a reset spring. A silicone water plug is installed at the connection between the sealing cover 3 and the water inlet 11 to better prevent water leakage and ensure a tighter connection between the sealing cover 3 and the water tank. The silicone water plug has the same shape as the water inlet 11.

[0057] In one embodiment, the present invention comprises a housing 1 and a water pipe connector 2. The housing 1 has a silicone water plug at its top, which opens the water inlet 11. The user then fills the tank with water and then closes the cover. The bottom has three ports connected to the water pipe connector 2, which is fixed to the interior of the cleaning robot and cannot be removed. The housing 1 is a separate, removable module secured by two movable bayonets.

[0058] In a specific embodiment, the top of the sealing cover 3 is provided with an opening mark, and the opening mark is used to guide the user to use it. Figure 13 shown.

[0059] It should be noted that the first outer sealing component, the first inner sealing component, and the water-adding silicone plug of the present application are all made of silicone. This is because silicone is heat-resistant when cleaned with warm water, and the silicone seal can withstand high temperatures. Silicone is also corrosion-resistant and aging-resistant: the silicone seal has good aging resistance, can maintain its elasticity for a long time, and is not prone to hardening or cracking. When repeatedly added with water, the silicone seal has good waterproof properties, can prevent water penetration, and is suitable for humid environments.

[0060] As an example, the box body 1 is connected to the machine body through the movable snap assembly 4 on both sides of the top of the box body 1 to form a cleaning robot. At the same time, the snap assembly 4 is detachably connected to the box body 1. The two snaps are symmetrically designed and fixed to the top left and top right of the box body 1 respectively. The sealing cover 3 is provided between the two snaps.

[0061] In a specific embodiment, the buckle assembly 4 includes a left buckle and a right buckle. The left buckle is arranged at the intersection of the left top and the side of the box body 1, and the right buckle is arranged at the intersection of the right top and the side of the box body 1.

[0062] In a specific embodiment, the box body 1 is a rectangular parallelepiped as a whole, and can also be a cube, etc. The edges of the box body 1 are chamfered to avoid right-angle injuries to users when users manually add water, thereby improving safety. Chamfering can reduce the sharp edges of the box body 1 and reduce the risk of scratches or cuts. The box body 1 can be made of plastic.

[0063] In the embodiment of the present application, a first valve plug 5 is provided at the bottom of the box body 1; the water pipe connector 2 is provided with a water injection connection port 21, and the water injection connection port 21 is adapted to the first valve plug 5; the first valve plug 5 includes a first return spring 51, a first valve plug 5 bracket, a first valve water outlet 53 and a first sealing component 54; the first valve plug 5 bracket is provided with a first return spring 51 inside, the first valve plug 5 bracket is provided with the first valve water outlet 53 in the middle, and the first valve plug 5 bracket is wrapped around the first sealing component 54. The cross-sectional structure diagram of the first valve plug 5 is shown as follows Figure 3 and Figure 5 shown.

[0064] In a specific embodiment, the first return spring 51 is arranged at the upper part of the inside of the first valve plug 5 bracket, and the first return spring 51 is a spring used to restore the device to its original position. The first return spring 51 is generally used in various mechanical and electronic equipment, such as valves. The first return spring 51 of the present application can be made of a variety of materials including metal plastic and rubber, preferably made of stainless steel. The working principle of the first return spring 51 is based on Hooke's law, which states that a spring or elastomer will deform when subjected to an external force, and when the external force is removed, it will try to return to its original unstressed state. When the first return spring 51 is compressed or stretched, it stores energy, and when the external force is removed, it releases the stored energy to restore the mechanical system or device to its original position. The first return spring 51 can be used in the valve plug to help the valve plug return to its original position and ensure reliable sealing, such as Figure 8 shown

[0065] As an example, the first valve plug 5 bracket is integrally formed and can be made of plastic or metal. A through hole is provided in the middle of the first valve plug 5 bracket, extending throughout the entire first valve plug 5 bracket. A first valve plug 5 buckle is provided on the outer ring of the top of the first valve plug 5 bracket to limit the position of the valve plug. The first valve plug 5 buckle cooperates with a limit ring provided at the bottom of the housing 1. When automatic water addition is performed, the first valve plug 5 bracket is lifted up, and the water outlet of the first valve plug 5 bracket is aligned with the water outlet of the limit ring at the bottom of the housing 1, and the valve plug is connected to the water filling connection port 21. A first valve water outlet 53 is provided in the middle of the first valve plug 5 bracket. The first valve water outlet 53 includes a left first valve water outlet 53 and a right first valve water outlet 53, which are symmetrically arranged. The first valve water outlet 53 and the water outlet of the limit ring at the bottom of the housing 1 have the same position and shape. A sealing silicone is provided at the bottom of the first valve plug 5 bracket. The sealing silicone comprises a second sealing ring, a third sealing ring, and a fourth sealing ring.

[0066] In an embodiment of the present application, a limiting ring is provided at the position where the valve plug is provided at the bottom of the box body 1, and a water tank outlet 12 is provided below the limiting ring. The water tank outlet 12 includes a left water tank outlet 12 and a right water tank outlet 12. The shape of the left water tank outlet 12 is the same as the position and shape of the left first valve outlet 53; the shape of the right water tank outlet 12 is the same as the position and shape of the right first valve outlet 53, so that the liquid can flow through the bottom of the first valve plug 5 bracket to the first valve outlet 53 and flow into the box body 1 from the water tank outlet 12.

[0067] As an example, the valve plug of the present application includes the first valve plug 5 and the second valve plug 6. The valve plug is also called valve stuffing or valve stuffing box, which is a key component of the valve. Its function is to prevent fluid leakage and maintain the sealing of the valve. The valve plug is made of metal or plastic. The main functions of the valve plug of the present application include preventing liquid leakage and liquid circulation with the outside world. To prevent liquid leakage, water is manually added when the box body 1 is lifted out of the machine body to prevent the residual liquid in the box body 1 from leaking through the valve. The valve plug fits tightly to the bottom of the box body 1 to prevent the fluid from leaking from the valve plug to the outside. During the working process of the valve plug, the valve plug can effectively prevent the leakage of the working liquid and ensure the normal operation of the system. The valve plug is an indispensable component in the valve. Its function is to ensure sealing and automatic water addition, prevent leakage and protect the normal operation of the cleaning robot.

[0068] In a specific embodiment, the function of the first valve plug 5 is to automatically add water. By connecting with the water pipe connector 2, the water pipe connector 2 is connected to the first valve plug 5. The liquid first passes through the water pipe connector 2 and then through the first valve plug 5, thereby achieving the purpose of automatic water addition.

[0069] In an embodiment of the present application, the first sealing assembly 54 includes a first outer sealing assembly and a first inner sealing assembly; the first outer sealing assembly is arranged at the connection between the first valve plug 5 bracket and the box body 1, and the first inner sealing assembly is arranged at the connection between the water injection connection port 21 and the first valve plug 5.

[0070] As an example, the first sealing assembly 54 is made of silicone. The first outer sealing assembly is used to seal the gap between the valve plug and the housing 1, thereby preventing liquid from flowing out of the outer ring of the valve plug. The first inner sealing assembly is used to seal the gap between the valve plug and the water injection connection port 21, thereby preventing liquid from flowing out of the ring around the water injection connection port 21.

[0071] In an embodiment of the present application, the first outer sealing assembly includes a first sealing ring arranged above the first valve water outlet 53 and a second sealing ring arranged below the first valve water outlet 53; the first inner sealing assembly includes a third sealing ring and a fourth sealing ring; the fourth sealing ring is arranged below the third sealing ring.

[0072] In a specific embodiment, the first outer sealing component is provided with a first sealing ring and a second sealing ring, the first sealing ring is used to seal the upper part of the water outlet of the valve plug, and the second sealing ring is used to seal the lower part of the water outlet of the valve plug, so that when automatic water addition is performed, the position of the valve plug will not leak; the first sealing ring and the second sealing ring are provided separately. Figure 9 and 10 As shown, when the box body 1 is placed in the main body of the machine, the valve plug is designed with two seals in the vertical direction and a sealing ring on the bottom, with a total of three sealing lines, which greatly increases the waterproof reliability during automatic water filling.

[0073] As an example, the first inner seal assembly is positioned inside the bracket of the first valve plug 5. The third and fourth sealing rings of the first inner seal assembly are integrally formed with the second sealing ring and arranged in a "U" shape at the bottom of the valve plug. The third and fourth sealing rings are positioned adjacent to each other and have the same shape, providing dual protection against liquid leakage from within the valve plug. After the user removes the housing 1 from the machine body, any residual water stains inside the housing 1 will not leak onto the user or the ground.

[0074] As an example, the water injection connection port 21 includes an outer ring and a column disposed in the middle. A through hole for communicating liquid is provided in the middle of the column of the water injection connection port 21. The column is used to lift the first valve plug 5 bracket. The first valve water outlet 53 is located opposite the water tank outlet 12, thereby automatically adding water through the water injection connection port 21. A space for accommodating the sealing silicone is provided between the column and the outer ring, thereby ensuring good sealing performance and preventing water leakage. The height of the column is higher than that of the outer ring, and the column is adapted to the valve plug.

[0075] In a specific embodiment, the water injection connection port 21, the mop water inlet connection port 22 and the drainage connection port 23 are all arranged on the bottom plate, and the bottom plate and the water injection connection port 21, the mop water inlet connection port 22 and the drainage connection port 23 are integrally formed, and the three are in a straight line. Figure 4 As shown. Preferably, the water injection connection port 21, the mop water inlet connection port 22 and the drainage connection port 23 can also be set separately. Figure 11 and Figure 12 As shown, the "E" port of the water pipe connector 2 is connected to the automatic water filling port, the "A" port is connected to the water inlet of the mop, and the "H" port is connected to the anti-explosion external port.

[0076] In this embodiment of the present application, a reflux assembly for preventing injection explosion is provided inside the housing 1; the water pipe connector 2 is provided with a drain connection port 23; and the reflux assembly is connected to the drain connection port 23. The reflux assembly includes a reflux channel 13, a reflux water pipe 14, and a reflux port 15; the reflux channel 13 is provided at the top inner side of the housing 1, one end of the reflux water pipe 14 is connected to the reflux channel 13, and the other end of the reflux water pipe 14 is connected to the reflux port 15; the reflux port 15 is provided at the bottom of the housing 1 and is connected to the drain connection port 23.

[0077] In a specific embodiment, if Figure 14 and Figure 15 As shown, when the cleaning robot returns to the base station for automatic water refilling, if the hardware sensor fails or misjudges the situation, the base station will continue to refill the water tank. The water tank will be under great pressure, and the water pressure may burst the tank. If this continues, the spreading water stains may cause short circuits in electronic components or corrode metal parts. Currently, a return pipe is designed at the highest point of the water tank. This pipe is directly connected to the outside of the main unit. The filled water will then flow out to the cleaning tank of the base station and then to the wastewater tank for recirculation.

[0078] As an example, a drainage connection port 23 is provided on one side of the water pipe connector 2. From left to right, the water pipe connector 2 is provided with a water injection connection port 21, a mop water inlet connection port 22, and a drainage connection port 23. The water injection connection port 21 is the same shape as the mop water inlet connection port 22, and the drainage connection port 23 is higher than the water injection connection port 21. When the water in the box body 1 is full, the water level is level with the top of the box body 1. The height of the position where the reflux channel 13 is provided on the top of the box body 1 is higher than the height of the top of the box body 1, so that water flows through the reflux channel 13 to discharge the water. One end of the reflux channel 13 is connected to the reflux pipe 14, and the reflux pipe 14 is connected to the reflux port 15. The reflux port 15 is connected to the drainage connection port 23. Liquid flows from the reflux channel 13 to the reflux pipe 14, then from the reflux pipe 14 to the reflux port 15, and then flows to the drainage connection port 23, thereby discharging excess water.

[0079] In one embodiment, the outer ring of the drainage connection port 23 is further provided with a sealing ring to prevent water from flowing out, providing a more airtight seal during drainage. The return water pipe 14 is a soft water pipe made of a flexible material, characterized by corrosion resistance, high temperature resistance, and pressure resistance. Soft water pipes can be made of materials such as stainless steel, copper, aluminum alloy, and polyvinyl chloride. They are rust-resistant and corrosion-resistant, making them suitable for transporting various corrosive liquids. They can withstand high temperatures and are suitable for hot water systems. They have high pressure resistance and can withstand certain pressures, making them suitable for high-pressure environments. They are also flexible and not prone to breakage or damage, making them suitable for complex and confined spaces. They are also lightweight and easy to install and maintain.

[0080] In a specific embodiment, the reflux assembly of the present application is used to prevent liquid from accumulating in the tank 1, which may cause explosion or circuit short circuit, thereby requiring the overflowing liquid to be discharged from the tank 1. In terms of automatic water filling, it has a mechanical anti-explosion function, and there is no hidden danger of failure caused by the circuit.

[0081] In the embodiment of the present application, the box body 1 is provided with a slope around the position where the second valve plug 6 is provided. Figure 6 and 7 As shown, the liquid levels of the water inlet and outlet of the valve plug are at the bottom of the box body 1 and are even lower than the bottom surface of the box body 1, so that the residual water can be pumped to the lowest point until it is drained.

[0082] In a specific embodiment, the slope is specifically provided at the location of the water tank outlet 12. The lowest liquid level at the water tank outlet 12 is lower than the bottom of the tank body 1, thereby forming a slope around the valve plug, which can improve the utilization rate of the tank body 1. The water level at the outlet of the tank body 1 is lower than the bottom of the tank, which can effectively drain the water for sweeping and mopping the floor.

[0083] In the embodiment of the present application, a second valve plug 6 is provided at the bottom of the box body 1 , and the water pipe connector 2 is provided with a mop water inlet connection port 22 ; the second valve plug 6 is adapted to the mop water inlet connection port 22 .

[0084] As an example, the mop water inlet connection port 22 is used to connect to the mop, and is used to pump out the water in the box body 1 for work. The second valve plug 6 has the same internal structure as the first valve plug 5, and the two are arranged side by side. The second valve plug 6 includes a second return spring, a second valve plug bracket, a second valve water outlet and a second sealing assembly; a second return spring is provided inside the second valve plug bracket, the second valve water outlet is provided in the middle of the second valve plug bracket, and the second sealing assembly is wrapped around the outside of the second valve plug bracket.

[0085] As an example, the second sealing assembly includes a second outer sealing assembly and a second inner sealing assembly; the second outer sealing assembly is arranged at the connection between the second valve plug bracket and the box body 1, and the second inner sealing assembly is arranged at the connection between the water injection connection port 21 and the second valve plug 6.

[0086] This application can achieve the following advantages: users can take out water to add, and the water can be automatically added after returning to the base station; it is convenient for different configuration selections of products. Figure 3 As shown, the sealing of the opening at the upper end of the box body 1 is completed by a silicone plug at the water inlet 11, and the sealing of the lower end is achieved by a first valve plug 5 and a second valve plug 6. The first valve plug 5 and the second valve plug 6 can move up and down in the box body 1.

[0087] In one embodiment, when the tank 1 is installed into the machine body, the upright post of the water injection connection of the water pipe connector 2 pushes the first valve plug 5 upward to its apex and stops. The first valve plug 5 overlaps with the water outlet of the tank 1, further connecting the water path and enabling both water injection and withdrawal. When the tank 1 is removed, the first valve plug 5, under the pressure of the first return spring 51, moves downward to the end of the buckle and stops. This creates an interlaced position between the water tank and the water inlet and outlet of the first valve plug 5, cleverly creating two sealing lines on the seal to prevent water leakage.

[0088] Next, a cleaning robot in this exemplary embodiment will be further described.
