Description

TECHNICAL FIELD

[0001] The present application relates to the field of robots, in particular to a cleaning basket and a cleaning robot. BACKGROUND

[0002] The existing garbage basket of the cleaning robot is equipped with a suction port and a suction cover plate, the suction cover plate is connected with the suction port through a rotating shaft and can rotate at the suction port. However, the existing cleaning robot may cause the rotating shaft to be stuck when the garbage falls near the rotating shaft, resulting in that the suction cover plate cannot completely close the suction port, and when the garbage basket is full of garbage, the garbage will fall from the suction port to the outside. CONTENT OF THE UTILITY MODEL

[0003] Therefore, the present application provides a cleaning basket and a cleaning robot to at least solve the technical problem that the suction cover plate of the cleaning robot is stuck and cannot be closed.

[0004] The cleaning basket provided by the first aspect of the present application comprises a bottom wall and a side wall, the side wall is connected to the bottom wall to form a collection space, the cleaning basket further comprises a protruding portion and a suction baffle provided on the bottom wall, the cleaning basket further comprises a suction port penetrating through the bottom wall and the protruding portion, one side of the suction baffle is provided with a rotating shaft, and the suction baffle is rotatably connected to the protruding portion through the rotating shaft to open or close the suction port, wherein the projection of the central axis of the rotating shaft on the bottom wall is located within the projection of the outer side wall of the protruding portion on the bottom wall.

[0005] Therefore, in the present application, when the suction baffle is in the state of opening the suction port, the pool water can enter the cleaning basket through the suction port and be discharged through the side wall of the cleaning basket, and the garbage in the pool water is blocked by the side wall and remains in the cleaning basket, achieving the purpose of cleaning the garbage in the pool. Since the projection position relationship between the rotating shaft and the outer side wall of the protruding portion is limited, the situation that the garbage falls to the position adjacent to the rotating axis of the rotating shaft to cause the rotating shaft to be stuck and the suction port to be unable to be closed can be avoided to a certain extent, so that it can be ensured that the garbage will not leak from the suction port when the cleaning basket is full. Moreover, compared with the situation that the water flow directly flows through the cleaning basket without the protruding portion, when the water flow flows through the suction passage formed by the protruding portion, the cross-sectional area of the water flow can be reduced, the flow rate of the water flow can be increased, the water flow passing capacity can be improved, and the cleaning efficiency can be improved.

[0006] In some embodiments, the protruding portion is a ring-shaped side wall;

[0007] The projection of the central axis of the rotating shaft on the bottom wall is located within the projection of the suction port on the bottom wall; or

[0008] The projection of the central axis of the rotating shaft on the bottom wall is located within the projection of the wall thickness center line of the ring-shaped side wall on the bottom wall.

[0009] Therefore, this application further defines the projected positional relationship between the rotating shaft and the protrusion, which can further prevent the shaft from getting stuck and unable to close the suction port when the garbage falls to the position of the rotation axis adjacent to the rotating shaft. Thus, it can be ensured that garbage will not leak out of the suction port when the cleaning basket is full.

[0010] In some embodiments, the extension direction of the protrusion is parallel to the height direction of the cleaning basket, and / or the protrusion is stepped.

[0011] Therefore, in this application, since the extension direction of the protrusion is approximately parallel to the height direction of the cleaning basket, that is, the extension direction of the suction channel is approximately parallel to the height direction of the cleaning basket, the resistance of water flow entering the cleaning basket from the suction channel can be reduced, the water flow capacity can be improved, and thus the cleaning efficiency can be improved. Moreover, the cross-sectional area of ​​the suction channel formed by the protrusion gradually decreases from the side near the bottom wall to the side away from the bottom wall, which can further increase the water flow velocity, improve the water flow capacity, and improve the cleaning efficiency.

[0012] In some embodiments, the end face of the protrusion facing away from the bottom wall is inclined relative to the bottom wall, and the suction baffle abuts against the end face.

[0013] Therefore, in this application, when the suction baffle is installed at an angle on the end face of the protrusion away from the bottom wall, the contact area between the suction baffle and the water flow direction is increased. Under the negative pressure generated by the water pump assembly, it is easier to suck the suction baffle open, which reduces the difficulty of the water pump assembly to open the suction baffle, and can also improve work efficiency and ensure that the cleaning robot can perform cleaning operations smoothly.

[0014] In some embodiments, the suction baffle includes a first side having a pivot and a second side opposite to the first side, the first side being at a smaller distance from the bottom wall than the second side is at a smaller distance from the bottom wall.

[0015] Therefore, in this application, the first side of the suction baffle with the rotating shaft is relatively low and the second side is relatively high, so that the negative pressure provided by the water pump assembly can more easily open the suction baffle, thereby reducing the negative pressure intensity required for the water pump assembly to open the suction baffle.

[0016] In some embodiments, the protrusion includes a first protruding wall and a second protruding wall disposed opposite to each other, as well as a third protruding wall and a fourth protruding wall disposed opposite to each other. The height of the third protruding wall is lower than the height of the fourth protruding wall. The end faces of the first and second protruding walls that are away from the bottom wall are inclined relative to the bottom wall and are adaptively connected to the end faces of the third and fourth protruding walls. The central axis of the rotating shaft is higher than the end face of the third protruding wall and lower than the end face of the fourth protruding wall.

[0017] Therefore, in this application, the first side of the suction baffle is connected to the side of the third protruding wall with a lower height, and the second side of the suction baffle is connected to the side of the fourth protruding wall with a higher height. In this way, under the negative pressure generated by the water pump assembly, it is easier to suck open the suction baffle, reducing the difficulty of the water pump assembly to open the suction baffle.

[0018] In some embodiments, the cleaning basket also includes an elastic element connected to the pivot. When the suction baffle is in the open suction port state, the elastic restoring force of the elastic element can force the suction baffle to return to the closed suction port state.

[0019] Therefore, in this application, the elastic restoring force of the elastic element can be used to automatically close the suction port, which can ensure that the suction baffle automatically restores and securely closes the suction port when it is not disturbed by external forces, effectively preventing garbage from leaking out of the suction port.

[0020] In some embodiments, the suction baffle includes a first side with a pivot and a second side opposite to the first side. The elastic element is a torsion spring, which includes a sleeve, a first arm and a second arm. The sleeve is mounted on the pivot, the first arm abuts against the surface of the suction baffle on the side opposite to the suction port, and the second arm abuts against the outer wall of the protrusion.

[0021] Therefore, the torsion spring can be installed more reliably on the rotating shaft of the suction baffle, improving the installation stability of the torsion spring, reducing the installation difficulty of the torsion spring, and making assembly easier.

[0022] In some embodiments, the suction baffle includes a first side having a pivot and a second side opposite to the first side, and a comb-shaped structure is provided on the surface of the suction baffle, the comb-shaped structure extending from the first side to the second side.

[0023] Therefore, the comb-shaped structure can guide the water flow into the cleaning basket more quickly.

[0024] The cleaning robot provided in the second aspect of this application includes the cleaning basket of the first aspect. Attached Figure Description

[0045] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the cleaning robot 100 in the embodiment of this application with the flip-top assembly 50 in the closed state. Figure 2 This is a schematic diagram of the cleaning robot 100 in the embodiment of this application with the flip-top assembly 50 in the open state. Figure 3 Examples of embodiments in this application Figure 2 A partially exploded view of the cleaning robot 100. In this embodiment, the cleaning robot 100 is a pool robot, which can be used to clean the bottom and walls of a swimming pool. In other embodiments, the cleaning robot 100 may be a sweeping robot, etc., and is not limited here.

[0046] like Figure 1 , Figure 2 and Figure 3As shown, the cleaning robot 100 includes a lower shell assembly 20, a walking assembly 30, an upper shell assembly 40, a flip-top assembly 50, a cleaning basket 10, a water pump assembly 60, and a cleaning brush assembly 70. The walking assembly 30 is mounted on opposite sides of the lower shell assembly 20. In some embodiments, the walking assembly 30 may be a track wheel assembly or a wheel assembly, which is not limited here. In this embodiment, the walking assembly 30 is a track wheel assembly. The upper shell assembly 40 is mounted on the lower shell assembly 20. The upper shell assembly 40 is recessed to form a mounting chamber 41, and a water pump chamber 42 is also formed between the upper shell assembly 40 and the lower shell assembly 20. The mounting chamber 41 and the water pump chamber 42 are arranged side-by-side with a gap. The cleaning basket 10 is detachably mounted inside the mounting chamber 41. The flip-top assembly 50 is rotatably connected to the upper shell assembly 40, and the flip-top assembly 50 can close onto the mounting chamber 41, or it can be opened relative to the mounting chamber 41. The water pump assembly 60 is mounted inside the water pump chamber 42. The cleaning brush assembly 70 is mounted on the front and / or rear side of the lower housing assembly 20.

[0047] Please refer to Figure 4 , Figure 5 and Figure 6 , Figure 4 for Figure 3 A three-dimensional structural diagram of the cleaning robot 100 after removing the flip-top assembly 50 and the cleaning basket 10. Figure 5 Examples of embodiments in this application Figure 1 A three-dimensional sectional view of the cleaning robot 100 at point AA. Figure 6 Examples of embodiments in this application Figure 1 The interface of the cleaning robot 100 at BB.

[0048] like Figure 4 As shown, the lower shell assembly 20 and the upper shell assembly 40 are provided with through openings 43 corresponding to the cleaning basket 10. The through openings 43 are connected to the suction port 103 at the bottom of the cleaning basket 10 (as shown in the image). Figure 5 (As shown) The cleaning brush assembly 70 is used to brush away dust, leaves, and other debris adhering to the bottom or walls of the pool, causing this debris to mix into the pool water. The water pump assembly 60 then uses negative pressure to pump the pool water mixed with debris into the cleaning basket 10 through the through-hole 43 and the suction port 103 at the bottom of the cleaning basket 10. Under the negative pressure of the water pump assembly 60, the pool water flows out from the side wall 102 of the cleaning basket 10 and is discharged through the outlet. Figure 5 and Figure 6 The arrows indicate the direction of water flow. Since the trash in the pool water cannot pass through the side wall 102 of the cleaning basket 10, it remains in the cleaning basket 10, thus achieving the cleaning of trash in the pool.

[0049] Please refer to Figure 7 , Figure 8 , Figure 9 and Figure 10, Figure 7 This is a three-dimensional structural diagram of the cleaning basket 10 in the embodiments of this application. Figure 8 Examples of embodiments in this application Figure 7 A three-dimensional cross-sectional view of the cleaning basket 10 at point CC. Figure 9 This is a three-dimensional cross-sectional view of the cleaning basket 10 in this embodiment of the application, excluding the suction baffle 104. Figure 10 This is a three-dimensional structural diagram of the suction baffle 104 in the embodiments of this application.

[0050] like Figures 7 to 10 As shown, the cleaning basket 10 includes a bottom wall 101 and a side wall 102. The side wall 102 is connected to the bottom wall 101 to form a collection space for collecting garbage. The cleaning basket 10 also includes a protrusion 105 and a suction baffle 104 provided on the bottom wall 101. The cleaning basket 10 also includes a suction port 103 that passes through both the bottom wall 101 and the protrusion 105. The suction baffle 104 is provided with a rotating shaft 1041. The suction baffle 104 is rotatably connected to the protrusion 105 via the rotating shaft 1041 to open or close the suction port 103. The projection of the central axis of the rotating shaft 1041 onto the bottom wall 101 is located within the projection of the outer side wall of the protrusion 105 onto the bottom wall 101.

[0051] Therefore, in this application, when the suction baffle 104 is in the open suction port 103 state, pool water can enter the cleaning basket 10 through the suction port 103 and be discharged through the side wall 102 of the cleaning basket 10. Meanwhile, the garbage in the pool water remains in the cleaning basket 10 due to being blocked by the side wall 102, thus achieving the purpose of cleaning the garbage in the pool. Furthermore, by defining the projected positional relationship between the rotating shaft 1041 and the outer side wall of the protrusion 105, the situation where garbage falls to a position adjacent to the rotation axis of the rotating shaft 1041, causing the rotating shaft 1041 to jam and preventing the suction port 103 from closing, can be avoided to a certain extent. Therefore, it can be ensured that when the cleaning basket 10 is full, garbage will not leak out from the suction port 103. Furthermore, since the protrusion 105 itself has a certain height, when the outer ring around the protrusion 105 is the storage space of the cleaning basket 10, since there is already a lot of storage space around the protrusion 105, the situation of garbage piling up on the suction baffle 104 can be reduced. In addition, compared with the case where water flows directly through the cleaning basket 10 without the protrusion, the protrusion 105 is provided on the bottom wall 101 of the cleaning basket 10. When the water flows through the suction channel formed by the protrusion 105, the cross-sectional area of ​​the water flow can be reduced, the flow velocity of the water flow can be increased, and the water flow capacity can be improved, thereby improving the cleaning efficiency.

[0052] In some embodiments, the protrusion 105 is an annular sidewall, and the projection of the central axis of the rotating shaft 1041 onto the bottom wall 101 lies within the projection of the outer sidewall of the protrusion 105 onto the bottom wall 101, including at least one of the following cases:

[0053] 1) The projection of the central axis of the rotating shaft 1041 onto the bottom wall 101 is located within the projection of the suction port 103 onto the bottom wall 101;

[0054] 2) The projection of the central axis of the rotating shaft 1041 onto the bottom wall 101 lies within the projection of the wall thickness midline of the annular sidewall onto the bottom wall 101.

[0055] Among them, the projection of the central axis of the rotating shaft 1041 on the bottom wall 101 is located within the projection of the suction port 103 on the bottom wall 101, including the case where the projection of the central axis of the rotating shaft 1041 on the bottom wall 101 coincides with the projection of the inner sidewall of the suction port 103 on the bottom wall 101, and the case where the projection of the central axis of the rotating shaft 1041 on the bottom wall 101 is located inside the projection of the inner sidewall of the suction port 103 on the bottom wall 101.

[0056] The projection of the central axis of the rotating shaft 1041 onto the bottom wall 101 is located within the projection of the wall thickness midline of the annular sidewall onto the bottom wall 101. This includes the case where the projection of the central axis of the rotating shaft 1041 onto the bottom wall 101 coincides with the projection of the wall thickness midline of the annular sidewall onto the bottom wall 101, and the case where the projection of the central axis of the rotating shaft 1041 onto the bottom wall 101 is located inside the projection of the wall thickness midline of the annular sidewall onto the bottom wall 101.

[0057] Therefore, in this application, the main factor affecting the closure of the suction baffle 104 is the debris deposited on the end face of the side wall (i.e., the third protruding wall 1055) adjacent to the rotating shaft 1041 of the annular sidewall. Therefore, in order not to affect the closure of the suction baffle 104, it is necessary to ensure that the end face of the side wall adjacent to the rotating shaft 1041 of the annular sidewall is free of debris or has minimal debris. Thus, when the projection of the central axis of the rotating shaft 1041 onto the bottom wall 101 is within the projection of the wall thickness midline of the annular sidewall onto the bottom wall 101, and the suction baffle 104 is opened at approximately the same level as the side wall adjacent to the rotating shaft 1041 of the annular sidewall, it can cover at least most of the side wall adjacent to the rotating shaft 1041 of the annular sidewall. Therefore, it can be ensured that the end face of the side wall adjacent to the rotating shaft 1041 of the annular sidewall is free of debris or has minimal debris, thereby ensuring that the suction baffle 104 can rotate and close normally to close the suction port 103. Of course, the rotating shaft 1041 can also be offset from the sidewall of the annular sidewall adjacent to the rotating shaft 1041, that is, the projection of the central axis of the rotating shaft 1041 on the bottom wall 101 is located within the projection of the suction port 103 on the bottom wall 101. In this way, even if some garbage is left at the edge of the end face of the sidewall of the annular sidewall adjacent to the rotating shaft 1041, it is ensured that the suction baffle 104 can rotate normally and close to close the suction port 103.

[0058] In some embodiments, the rotating shaft 1041 can be directly connected to the wall surface inside the suction port 103, or the rotating shaft 1041 can be connected to the wall surface inside the suction port 103 through an intermediate element. In this embodiment, the rotating shaft 1041 is directly connected to the wall surface inside the suction port 103.

[0059] In some embodiments, the storage space of the cleaning basket 10 refers to the area inside the cleaning basket 10 with the suction baffle 104 as the boundary when the suction baffle 104 is closed over the suction port 103.

[0060] In some embodiments, such as Figure 7 As shown, the sidewall 102 includes a frame 1021 and a filter screen 1022. The frame 1021 is connected to the bottom wall 101, and the filter screen 1022 is disposed on the frame 1021.

[0061] Thus, the frame 1021 provides the structural strength required for the sidewalls 102 of the cleaning basket 10, while the filter screen 1022 is fixed to the frame 1021 to form a water passage area, but can filter out garbage in the pool water.

[0062] In some embodiments, such as Figure 8 and Figure 9 As shown, the bottom wall 101 has a through hole 1011, and the protruding part 105 is hollow to form a through hole 1051, which communicates with the through hole 1011. The suction port 103 includes a suction channel formed by the through hole 1011 and the through hole 1051. The outer ring around the protruding part 105 is the storage space for the cleaning basket 10.

[0063] In some embodiments, the extension direction of the protrusion 105 is generally parallel to the height direction of the cleaning basket 10. The height direction refers to the direction represented by the Z-axis in the figure. The positive direction of the Z-axis is high, and the negative direction is low.

[0064] Therefore, since the extension direction of the protrusion 105 is approximately parallel to the height direction of the cleaning basket 10, that is, the extension direction of the suction channel is approximately parallel to the height direction of the cleaning basket 10, the resistance of water flow from the suction channel into the cleaning basket 10 can be reduced, the water flow capacity can be improved, and thus the cleaning efficiency can be improved.

[0065] In some embodiments, the height of the protrusion 105 is approximately 1 / 4 to 1 / 2 of the height of the cleaning basket 10.

[0066] Therefore, by limiting the height ratio of the protrusion 105 to the cleaning basket 10, it can be ensured that the water flow is sufficiently accelerated in the suction channel, thereby improving the water flow capacity and cleaning efficiency.

[0067] In some embodiments, the protrusion 105 is stepped to form a stepped structure, and the outer ring size of the protrusion 105 on the side closer to the bottom wall 101 is larger than the outer ring size of the protrusion 105 on the side farther from the bottom wall 101.

[0068] Therefore, the cross-sectional area of ​​the suction channel formed by the protrusion 105 gradually decreases from the side near the bottom wall 101 to the side away from the bottom wall 101, which can further increase the water flow velocity, improve the water flow capacity, and improve the cleaning efficiency.

[0069] In some embodiments, the stepped structure of the protrusion 105 engages precisely with the edge protrusion of the through opening 43 within the mounting chamber 41 (e.g., Figure 5 As shown, it can be used to position the cleaning basket 10 during installation.

[0070] In some embodiments, please refer to Figure 9 The end face 1052 of the protrusion 105 facing away from the bottom wall 101 is inclined relative to the bottom wall 101, and the suction baffle 104 is inclinedly installed on the end face 1052.

[0071] Therefore, when the suction baffle 104 is installed at an angle on the end face 1052 of the protrusion 105 that is away from the bottom wall 101, the contact area between the suction baffle 104 and the water flow direction is increased. Under the negative pressure generated by the water pump assembly 60, it is easier to suck the suction baffle 104 open, which reduces the difficulty for the water pump assembly 60 to open the suction baffle 104, and can also improve work efficiency, ensuring that the cleaning robot 100 can perform cleaning operations smoothly.

[0072] In some embodiments, please refer to Figure 9 The protruding portion 105 includes a first protruding wall 1053 and a second protruding wall 1054 disposed opposite to each other (e.g., Figure 12 As shown), a third protruding wall 1055 and a fourth protruding wall 1056 are arranged opposite to each other. The height of the third protruding wall 1055 is lower than the height of the fourth protruding wall 1056. The end faces of the first protruding wall 1053 and the second protruding wall 1054 that are away from the bottom wall 101 are inclined relative to the bottom wall 101 and are adaptively connected to the end faces of the third protruding wall 1055 and the fourth protruding wall 1056. The protruding part 105 also includes a first mounting part 1057 provided on the first protruding wall 1053 near the third protruding wall 1055, and a second mounting part 1058 provided on the second protruding wall 1054 near the third protruding wall 1055. The first mounting part 1057 is provided with a first shaft hole 1057a, and the second mounting part 1058 is provided with a second shaft hole. The two ends of the rotating shaft 1041 are respectively connected to the first shaft hole 1057a and the second shaft hole.

[0073] Thus, the rotating shaft 1041 of the suction baffle 104 is connected between the first protruding wall 1053 and the second protruding wall 1054 respectively, thereby enhancing the connection stability and structural reliability of the suction baffle 104.

[0074] In some embodiments, the first mounting portion 1057 and the second mounting portion 1058 are respectively higher than the first protruding wall 1053 and the second protruding wall 1054. The central axis of the rotating shaft 1041 is higher than the end face of the third protruding wall 1055 and lower than the end face of the fourth protruding wall 1056.

[0075] Therefore, in this application, the side of the suction baffle 104 with the pivot 1041 is connected to the side of the lower third protruding wall 1055, and the other side of the suction baffle 104 is connected to the side of the higher fourth protruding wall 1056. In this way, under the negative pressure generated by the water pump assembly 60, it is easier to suck open the suction baffle 104, reducing the difficulty for the water pump assembly 60 to open the suction baffle 104.

[0076] In some embodiments, the first mounting portion 1057 and the second mounting portion 1058 are both plate-shaped and extend to the side of the third protruding wall 1055 opposite to the fourth protruding wall 1056. Preferably, the first mounting portion 1057 and the second mounting portion 1058 may also extend to connect with the bottom wall 101.

[0077] Therefore, since the first mounting portion 1057 and the second mounting portion 1058 extend to the side of the third protruding wall 1055 away from the fourth protruding wall 1056, preferably, the first mounting portion 1057 and the second mounting portion 1058 can also extend to connect with the bottom wall 101, which can greatly improve the structural strength of the first mounting portion 1057 and the second mounting portion 1058, thereby enhancing the overall structural strength and reliability of the cleaning basket 10.

[0078] In some embodiments, such as Figure 7 and Figure 8 As shown, the cleaning basket 10 also includes a cover 108, which is connected to the side wall 102 and has an open state (opening the cleaning basket 10) and a closed state (closing the cleaning basket 10).

[0079] In some embodiments, please refer to Figure 10 The rotating shaft of the suction baffle 104 is a long shaft that can extend from the side of the first protruding wall 1053 to the side of the second protruding wall 1054, and is connected between the first protruding wall 1053 and the second protruding wall 1054 respectively. Moreover, the long shaft itself is the structure of the suction baffle 104 that is closest to the third protruding wall 1055.

[0080] Therefore, in this application, as long as the projected positional relationship between the rotating shaft 1041 and the protrusion 105 is clearly defined, it is possible to avoid the situation where the rotating shaft 1041 gets stuck and cannot close the suction port 103 when the garbage falls to the position of the rotation axis adjacent to the rotating shaft 1041. Thus, it can be ensured that garbage will not leak out of the suction port 103 when the cleaning basket 10 is full.

[0081] In some embodiments, the suction baffle 104 includes a first side 1042 having a pivot 1041 and a second side 1043 opposite to the first side 1042, wherein the distance of the first side 1042 from the bottom wall 101 is less than the distance of the second side 1043 from the bottom wall 101.

[0082] Therefore, the first side 1042 of the suction baffle 104 with the pivot 1041 is relatively low and the second side 1043 is relatively high, so that the negative pressure provided by the pump assembly 60 can more easily open the suction baffle 104, thereby reducing the negative pressure intensity required for the pump assembly 60 to open the suction baffle 104.

[0083] In other embodiments, the distance between the first side 1042 and the bottom wall 101 may be greater than or equal to the distance between the second side 1043 and the bottom wall 101, and this is not limited here.

[0084] In some embodiments, please refer to Figure 10 The suction baffle 104 has a torsion spring mounting seat 1044 on its rotating shaft 1041. In this embodiment, the diameter of the torsion spring mounting seat 1044 is equal to the diameter of the rotating shaft 1041. In other embodiments, the diameter of the torsion spring mounting seat 1044 is larger than the diameter of the rotating shaft 1041, depending on the structure of the elastic element, and is not limited here.

[0085] In some embodiments, such as Figure 10 As shown, a comb-shaped structure 1045 is provided on the surface of the suction baffle 104, which extends from the first side 1042 to the second side 1043. The comb-shaped structure 1045 gradually tapers from the first side 1042 to the second side 1043.

[0086] Thus, the comb-shaped structure 1045 can guide the water flow into the cleaning basket 10 more quickly.

[0087] In other embodiments, the protrusion 105 may be omitted, and the suction port 103 may be a through hole 1011 provided on the bottom wall 101.

[0088] This simplifies the structural design of the rotating shaft 1041 located on the wall inside the suction port 103 or inside the suction port 103.

[0089] In some embodiments, please refer to Figure 10 and Figure 11The cleaning basket 10 also includes an elastic element 107, which is connected to the rotating shaft 1041. When the suction baffle 104 is in the open suction port 103 state, the elastic restoring force of the elastic element 107 can force the suction baffle 104 to return to the closed suction port 103 state.

[0090] Therefore, the elastic restoring force of the elastic element 107 can automatically close the suction port 103, ensuring that the suction baffle 104 automatically restores and securely closes the suction port 103 when not disturbed by external forces, effectively preventing garbage from leaking out of the suction port 103.

[0091] Elastic element 107 is a torsion spring, such as Figure 11 and Figure 12 As shown, the torsion spring includes a sleeve portion 1071, a first arm 1072, and a second arm 1073. The sleeve portion 1071 is mounted on the torsion spring mounting base 1044. The first arm 1072 abuts against the surface of the suction baffle 104 on the side opposite to the suction port 103. The second arm 1073 abuts against the outer wall of the protrusion 105 (e.g., Figure 11 As shown), it can specifically abut against the outer wall of the third protruding wall 1055.

[0092] Therefore, the torsion spring can be installed more reliably on the suction baffle 104, improving the installation stability of the torsion spring, reducing the installation difficulty, and facilitating assembly.

[0093] In some embodiments, such as Figure 12 As shown, the elastic element 107 is a single unit, which is disposed on one end of the suction baffle 104 located on the first side 1042.

[0094] Therefore, by utilizing the elastic force of the elastic element 107, sufficient tension can be provided to ensure a seal when the suction port 103 is closed. It should be noted that the opening of the suction baffle 104 relies on the negative pressure generated by the water pump assembly 60 to pull the suction baffle 104 open and maintain its open state. If elastic elements 107 are provided at both ends of the suction baffle 104 located on the first side 1042, opening the suction baffle 104 will become relatively difficult because the interaction of the elastic elements 107 on both sides will increase the negative pressure required for opening, which may affect the normal opening of the suction baffle 104. Therefore, the design of providing an elastic element 107 on only one side can better balance the opening and closing of the suction baffle 104, ensuring its flexibility and reliability under different operating conditions.

[0095] In other embodiments, there may be two elastic elements 107, which is not limited here.

[0096] In some embodiments, please refer to Figure 13The suction port 103 is rectangular, and the bottom wall 101 of the cleaning basket 10 is also adapted to be rectangular. Moreover, the length and width ratios of the suction port 103 and the bottom wall 101 of the cleaning basket 10 are roughly the same. In this way, the storage space of the cleaning basket 10 around the protrusion 105 is relatively consistent, avoiding local areas being too narrow.

[0097] It is understood that in other embodiments, the suction port 103 may also be circular, square or polygonal, etc. Correspondingly, the bottom wall 101 of the cleaning basket 10 may also be adapted to be circular, square or polygonal, etc., without limitation.

[0098] Please refer to Figure 14 In other embodiments, the end face 1052 of the third protruding wall 1055 adjacent to the pivot 1041 is set as an inclined surface, so that the contact between the suction baffle 104 and the end face 1052 of the third protruding wall 1055 is a line contact. Since the end face 1052 of the third protruding wall 1055 is set as an inclined surface, the end face 1052 of the third protruding wall 1055 is basically free of garbage, so it will not affect the closing of the suction baffle 104.

[0099] Preferably, all end faces 1052 of the top of the annular sidewall of the protrusion 105 are set as inclined surfaces, so that the suction baffle 104 and the end faces 1052 of the annular sidewall are adjusted to line contact.

[0100] In this way, the four ends of the annular sidewall of the protrusion 105 will not bear garbage. Therefore, the problem of the suction baffle 104 being unable to close due to garbage accumulation on the annular sidewall of the protrusion 105 can be better solved. It is no longer necessary to limit the positional relationship between the pivot 1041 of the suction baffle 104 and the sidewall of the annular sidewall of the protrusion 105 adjacent to the pivot 1041. The pivot 1041 of the suction baffle 104 can be located on the outside, top, or inside of the annular sidewall of the protrusion 105.

[0101] Please refer to Figure 15 In another embodiment, the end face 1052 of the third protruding wall 1055 and the rotating shaft 1041 of the suction baffle 104 are connected by a ball joint. That is, the end face 1052 of the third protruding wall 1055 is a cylindrical protruding surface, and the rotating shaft 1041 of the suction baffle 104 is a cylindrical groove surface. The two are engaged. In this way, the cylindrical groove surface is engaged with the cylindrical protruding surface, and the cylindrical protruding surface is covered by the cylindrical groove surface. The cylindrical protruding surface will not bear garbage, so there is no problem of shaft jamming caused by garbage falling on the cylindrical protruding surface. At this time, the central axis of the rotating shaft 1041 of the suction baffle 104 coincides with the center line of the wall thickness of the annular sidewall. That is, the projection of the central axis of the rotating shaft 1041 of the suction baffle 104 on the bottom wall 101 is located on the projection of the center line of the wall thickness of the annular sidewall on the bottom wall 101.

[0102] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this application, and these all fall within the protection scope of this application.
