At present, the water tanks of sweeping robots are divided into inner and outer water tanks, and the connection method is generally that the inner water tank is directly installed in the outer water tank.

[0003] This design has some shortcomings in actual use. First, when the sweeping robot works for a long time, due to the continuous action of water and the pressure changes between the inner and outer water tanks, the side walls of the inner and outer water tanks are prone to deformation. Secondly, if the amount of water is large, the overall weight of the water tank increases, which will also increase the pressure on the side wall, making the side wall more prone to deformation. The deformation of the side wall of the water tank will not only affect the appearance of the sweeping robot, but may also cause the sealing of the water tank to deteriorate, resulting in water leakage and other problems, thereby affecting the normal use and cleaning effect of the sweeping robot. In addition, the deformed water tank may affect the operating stability of the sweeping robot and reduce its working efficiency. Utility Model Content

[0036] Reference Figure 1-Figure 5 , this embodiment provides a water tank structure, including an inner water tank 1 and an outer water tank 2;

[0037] The outer water tank 2 is provided with a receiving chamber, the inner water tank 1 is provided in the receiving chamber and connected to the outer water tank 2, and a designated interval 3 is formed between the inner water tank 1 and the outer water tank 2;

[0038] A plurality of abutting members 4 protruding toward the inner water tank 1 are provided on one side of the outer water tank 2 . The abutting members 4 are located in the designated interval 3 and connected to the inner water tank 1 .

[0039] In the above embodiment, the water tank structure includes an inner water tank 1 and an outer water tank 2, wherein the inner water tank 1 is located inside the outer water tank 2, and the outer water tank 2 has a accommodating chamber, which provides a placement space for the inner water tank 1 and protects and supports the overall water tank structure. The accommodating chamber is the space inside the outer water tank 2, which is specifically used to place the inner water tank 1. A plurality of push-up members 4 are arranged on one side of the outer water tank 2 and protrude toward the inner water tank 1. They are located in a designated interval 3 formed between the inner water tank 1 and the outer water tank 2 and are connected to the inner water tank 1. These push-up members 4 are a reinforcing structure for sharing the pressure between the inner and outer water tanks 2. The inner water tank 1 is placed in the accommodating chamber and connected to the outer water tank 2 with a designated interval 3 between the two. The push-up members 4 on one side of the outer water tank 2 are connected to the inner water tank 1 in the interval. This connection method makes the entire water tank structure more stable. When assembling the water tank structure, first place the inner water tank 1 in the accommodating chamber of the outer water tank 2 so that the two maintain a certain designated interval 3. Then, the push piece 4 on one side of the outer water tank 2 is connected to the inner water tank 1. The connection process needs to ensure that the push piece 4 is positioned accurately so that it can effectively share the pressure. During use, when water is added to the inner water tank 1, as the amount of water increases, the pressure between the inner and outer water tanks 2 changes, but due to the presence of the push piece 4, the pressure is reasonably shared and will not cause deformation of the side wall. When the sweeping robot starts working and moves, the water tank structure remains stable, providing a stable water supply for cleaning work and ensuring the cleaning effect. By setting the push piece 4, the pressure between the inner and outer water tanks 2 due to the pressure of water and the weight of the water tank is effectively shared. When the sweeping robot works for a long time or the amount of water is large, the risk of deformation of the side walls of the inner and outer water tanks 2 can be reduced, the stability and durability of the water tanks can be improved, the sealing between the inner and outer water tanks 1 and 2 is ensured, and the possibility of water leakage is reduced, thereby ensuring the safety and cleaning effect of the sweeping robot at work, and ultimately improving the working efficiency of the sweeping robot.

[0040] Reference Figure 1-Figure 2 In one embodiment, the push member 4 is a top opening structure, the top opening of the push member 4 is connected to the outer wall of the outer water tank 2 to form a transition portion 5, and the push member 4 and the outer water tank 2 are an integral part.

[0041] In the above embodiment, the supporting member 4 is a top opening structure, wherein the top opening refers to the opening part of the top of the supporting member 4, the supporting member 4 is located on one side of the outer water tank 2 and protrudes toward the inner water tank 1, and its top opening is connected to the outer wall of the outer water tank 2, and an arc-shaped transition portion 5 is formed at the connection, and the supporting member 4 and the outer water tank 2 are an integral part. The top opening structure of the supporting member 4 and the transition portion 5 at the connection with the outer wall of the outer water tank 2 are designed so that when under pressure, the force can be more evenly distributed at the connection part between the supporting member 4 and the outer water tank 2, avoiding damage caused by stress concentration. Since the supporting member 4 and the outer water tank 2 are an integral part, this one-piece structure greatly enhances the overall strength of the water tank structure. During the operation of the sweeping robot, whether it is running for a long time or there is a lot of water in the water tank, it can effectively prevent the side walls of the inner and outer water tanks 2 from deforming, which not only ensures the sealing of the water tank and reduces the risk of water leakage, but also ensures the normal operation and cleaning effect of the sweeping robot, thereby improving its working efficiency and service life.

[0042] Reference Figure 1-Figure 5 In one embodiment, the end of the resisting member 4 away from the top opening forms an arc-shaped connecting end 6, the inner diameter of the resisting member 4 gradually decreases from the top opening toward the arc-shaped connecting end 6, and the diameter of the arc-shaped connecting end 6 is less than or equal to half the diameter of the top opening.

[0043] In the above embodiment, the arc-shaped connecting end 6 is the end of the supporting member 4 away from the top opening, which is in an arc shape and is used to connect with the inner water tank 1 or a related supporting structure. One end of the supporting member 4 is the top opening connected to the outer wall of the outer water tank 2, and there is a transition portion 5 at the connection, and the other end is the arc-shaped connecting end 6, which is located gradually extending from the top opening toward the inner water tank 1, and the inner diameter gradually decreases. This gradual inner diameter design makes the supporting member 4 structurally conical, and the diameter of the arc-shaped connecting end 6 is less than or equal to half the diameter of the top opening, so that the supporting member 4 can better adapt to the space and pressure distribution between the inner and outer water tanks 2, and is effectively connected to the inner water tank 1 or other supporting structures through the arc-shaped connecting end 6, so that the pressure borne by the outer water tank 2 is reasonably transmitted and shared, and the inner diameter of the supporting member 4 is gradually reduced from The design of the top opening gradually decreasing toward the arc-shaped connecting end 6 allows the push piece 4 to better disperse the force when under pressure. When there is pressure between the inner and outer water tanks 2, this structure can make the pressure evenly distributed along the gradual inner diameter of the push piece 4, avoiding damage caused by excessive local pressure. The limitation of the diameter of the arc-shaped connecting end 6 (less than or equal to half the diameter of the top opening) makes the push piece 4 more stable when connected to the inner water tank 1 or related supporting structure, and can fit more closely to the surface of the inner water tank 1, providing more effective support and pressure sharing. During the operation of the sweeping robot, this structure can effectively prevent the side walls of the inner and outer water tanks 2 from deforming, ensure the sealing and stability of the water tank, and thereby ensure the cleaning effect and working efficiency of the sweeping robot, and extend the service life of the water tank and the entire robot.

[0044] Reference Figure 1-Figure 5 In one embodiment, a support pad 7 is provided at one end of the abutting member 4 close to the outer wall of the inner water tank 1, and the arc-shaped connecting end 6 of the abutting member 4 is connected to the outer wall of the inner water tank 1 through the support pad 7, and the diameter of the support pad 7 is greater than or equal to the diameter of the arc-shaped connecting end 6.

[0045] In the above embodiment, the support pad 7 is a component provided at one end of the abutting member 4 close to the outer wall of the inner water tank 1, which plays a role of buffering and better connection. The arc-shaped connecting end 6 of the abutting member 4 is close to the outer wall of the inner water tank 1, and a support pad 7 is provided between the two. The diameter of the support pad 7 is greater than or equal to the diameter of the arc-shaped connecting end 6, which enables the support pad 7 to completely cover the area where the arc-shaped connecting end 6 contacts the inner water tank 1. The abutting member 4 is connected to the outer wall of the inner water tank 1 through the support pad 7. This connection method can better transmit pressure while avoiding direct hard contact between the abutting member 4 and the outer wall of the inner water tank 1. When there is a pressure between the inner and outer water tanks 2, the pressure When the pressure changes, the support pad 7 can buffer the pressure and prevent damage such as scratches or deformation to the outer wall of the inner water tank 1 due to excessive or uneven pressure, thereby protecting the structural integrity of the inner water tank 1. Since the diameter of the support pad 7 is greater than or equal to the diameter of the arc-shaped connecting end 6, it can cover the contact area more comprehensively, making the pressure more uniform during the transmission process, which helps to improve the stability of the entire water tank structure and further reduce the risk of deformation of the side walls of the inner and outer water tanks 2. During the operation of the sweeping robot, this structure can ensure the sealing of the water tank, ensure the cleaning effect and work efficiency, and extend the service life of the water tank and the entire robot.

[0046] Reference Figure 1-Figure 5 In one embodiment, a plurality of the push members 4 are arranged in an array on the outer water tank 2, and a plurality of first reinforcing ribs 8 are arranged at longitudinal or transverse intervals between adjacent push members 4. The first reinforcing ribs 8 are recessed toward the inner water tank 1, and the first reinforcing ribs 8 extend along the length or width direction of the outer water tank 2.

[0047] In the above embodiment, the first reinforcing rib 8 is a structural component provided on the outer water tank 2 and located between adjacent resisting members 4. Its main function is to enhance the strength of the outer water tank 2. A plurality of resisting members 4 are arranged in an array on the outer water tank 2. This array arrangement enables the resisting members 4 to be evenly distributed on one side of the outer water tank 2, thereby more effectively sharing the pressure between the inner and outer water tanks 2. A plurality of first reinforcing ribs 8 are provided between adjacent resisting members 4. These first reinforcing ribs 8 are arranged at intervals in the longitudinal or transverse direction. They are concave toward the inner water tank 1 and extend along the length or width of the outer water tank 2. The outer water tank 2 is provided with a plurality of reinforcing ribs 8, and the outer water tank 2 is provided with a plurality of reinforcing ribs 8. The reinforcing ribs 8 extend in the degree direction, so that the first reinforcing ribs 8 and the push-up members 4 cooperate with each other to jointly enhance the structural strength of the outer water tank 2. The first reinforcing ribs 8 form an additional supporting structure between adjacent push-up members 4, further improving the ability of the outer water tank 2 to resist pressure deformation. The array arrangement of multiple push-up members 4 and the setting of the first reinforcing ribs 8 greatly improve the structural strength of the outer water tank 2. When the sweeping robot is working, no matter it is running for a long time or there is a large amount of water in the water tank, the outer water tank 2 can better withstand the pressure between the inner and outer water tanks 2, reducing the risk of side wall deformation.

[0048] Reference Figures 1-10In one embodiment, a plurality of second reinforcing ribs 9 and third reinforcing ribs 10 recessed toward the inner water tank 1 are further provided on the outer wall of the outer water tank 2, and the second reinforcing ribs 9 and the third reinforcing ribs 10 are arranged opposite to each other, and the second reinforcing ribs 9 and the third reinforcing ribs 10 are respectively arranged adjacent to the first reinforcing ribs 8, and the second reinforcing ribs 9 and the third reinforcing ribs 10 respectively extend along the length or width direction of the outer water tank 2.

[0049] In the above embodiment, the second reinforcing ribs 9 and the third reinforcing ribs 10 are structural components arranged on the outer wall of the outer water tank 2, and are used to enhance the strength of the outer water tank 2. The second reinforcing ribs 9 and the third reinforcing ribs 10 are located on the outer wall of the outer water tank 2. They are arranged relative to each other, which means that the second reinforcing ribs 9 and the third reinforcing ribs 10 are symmetrical in position and are respectively located on both sides of the outer water tank 2 (in terms of relative directions). In addition, the second reinforcing ribs 9 and the third reinforcing ribs 10 are respectively arranged adjacent to the first reinforcing ribs 8. For example, the second reinforcing ribs 9 are adjacent to the first reinforcing ribs 8 on one side, and the third reinforcing ribs 10 are adjacent to the first reinforcing ribs 8 on the other side. At the same time, the second reinforcing ribs 9 and the third reinforcing ribs The ribs 10 extend along the length or width direction of the outer water tank 2 respectively. This extension direction may be the same as the extension direction of the first rib 8 (depending on the structural design of the outer water tank 2), so that these ribs form an interconnected network structure to jointly enhance the overall strength of the outer water tank 2. The second ribs 9 and the third ribs 10 work together with the first ribs 8 to greatly enhance the structural strength of the outer water tank 2. This multi-layer rib design enables the outer water tank 2 to better resist deformation when it is under pressure between the inner and outer water tanks 2. Regardless of whether the sweeping robot is working for a long time or there is a large amount of water in the water tank, the outer water tank 2 can maintain its stable shape.

[0050] Reference Figures 1-11 In one embodiment, an inlet and outlet water pipe 11 is provided inside the outer water tank 2 on a side away from the push member 4, and a avoidance platform 12 is provided on a side of the inner water tank 1 adjacent to the inlet and outlet water pipe 11, and the inner water tank 1 is connected to the inlet and outlet water pipe 11 through the avoidance platform 12.

[0051] In the above embodiment, the inlet and outlet pipes 11 are pipes for water to enter and exit the water tank, and are arranged inside the outer water tank 2 on the side away from the top member 4. They are channels for the water tank to exchange water with an external water source or cleaning components. The avoidance platform 12 is a structural part on the inner water tank 1, and is arranged on the side adjacent to the inlet and outlet pipes 11. Its function is to provide space for the inlet and outlet pipes 11 to avoid interference. The inlet and outlet pipes 11 are located at a specific position inside the outer water tank 2, away from the side of the top member 4. The inner water tank 1 is placed in the accommodating chamber of the outer water tank 2. When the two are combined, the avoidance platform 12 of the inner water tank 1 corresponds to the inlet and outlet pipes 11 of the outer water tank 2. Through the design of the avoidance platform 12, the inner water tank 1 and the inlet and outlet pipes 11 are connected. This connection The method ensures that water can smoothly enter the inner water tank 1 from the inlet and outlet pipes 11, or flow out from the inner water tank 1 through the inlet and outlet pipes 11, and at the same time will not affect the flow of water or the normal use of the water tank due to structural interference. The design of the inlet and outlet pipes 11 and the avoidance platform 12 makes the filling and drainage process of the water tank smoother, and water can enter and exit the water tank efficiently, ensuring that the sweeping robot has sufficient water supply during the cleaning process. At the same time, it can also discharge waste water in time to maintain the cleaning effect, avoiding damage that may be caused by interference between the inlet and outlet pipes 11 and the inner water tank 1, and the avoidance platform 12 provides a suitable space for the inlet and outlet pipes 11, reduces the friction and collision risk between components, and improves the stability and durability of the water tank structure.

[0052] Reference Figures 1-9 In one embodiment, a first extension platform 13 is provided on the side of the inner water tank 1 opposite to the push member 4, and a second extension platform 14 and a third extension platform 15 are respectively provided on both sides of the inner water tank 1 adjacent to the first extension platform 13, which are symmetrical to each other, and the height of the first extension platform 13 from the bottom of the inner water tank 1 is less than the height of the second extension platform 14 and the third extension platform 15 from the bottom of the inner water tank 1.

[0053] In the above embodiment, the first extension platform 13 is a platform structure provided on the side of the inner water tank 1 opposite to the top member 4, the second extension platform 14 and the third extension platform 15 are respectively provided on both sides of the inner water tank 1 adjacent to the first extension platform 13, and are symmetrical to each other. The first extension platform 13 is located on one side of the inner water tank 1, opposite to the top member 4, and the second extension platform 14 and the third extension platform 15 are adjacent to each other on both sides of the first extension platform 13. From the height point of view, the height of the first extension platform 13 from the bottom of the inner water tank 1 is less than the height of the second extension platform 14 and the third extension platform 15 from the bottom of the inner water tank 1. This height difference makes the inner water tank 1 present a special shape in structure. The extension platform 14 and the third extension platform 15 make the upper space of the entire inner water tank 1 larger than the lower space, effectively increasing the accommodation space of the entire inner water tank 1. The setting of the extension platform enhances the structural stability of the inner water tank 1. The extension platforms of different heights enable the inner water tank 1 to better disperse the pressure when subjected to external force. For example, when the sweeping robot shakes or collides during movement, the extension platform can disperse the external force to different parts, reducing the situation of local excessive force, thereby protecting the structural integrity of the inner water tank 1. In addition, when the inner water tank 1 is filled with water or drained, the symmetrical platform structure can guide the water to flow more evenly, avoiding local water accumulation or poor water flow, thereby improving the use efficiency and cleaning effect of the water tank.

[0054] The present utility model also provides a sweeping robot, comprising the water tank structure described in any one of the above embodiments.

[0055] In the above embodiment, the sweeping robot includes a water tank structure. The push-up member 4 in the water tank structure serves as a reinforcing structure to share the pressure between the inner and outer water tanks 2. Regardless of whether the sweeping robot works for a long time or there is a large amount of water in the water tank, the possibility of deformation of the side walls of the inner and outer water tanks 2 can be effectively reduced. For example, when the robot cleans continuously for several hours, the water tank continues to bear the weight of the water and the pressure generated by the shaking. The push-up member 4 can prevent the side wall from being deformed due to excessive pressure, thereby effectively improving the safety and work efficiency of the entire sweeping robot.
