However, it will be apparent to those skilled in the art that the present application can be implemented without one or more of these details. In other examples, some technical features well known in the art are not described in order to avoid confusion with the present application.

[0030] It should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0031] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0032] As shown in Figures 1 to 4, embodiments of the present application provide a sewage tank, cleaning equipment, and a cleaning system. The sewage tank can be used on the cleaning equipment, and the cleaning system includes the cleaning equipment and a base station, that is, the base station and the cleaning equipment are used in conjunction with each other.

[0033] Specifically, as shown in Figure 1, the cleaning equipment includes a main body 1, which is provided with a driving motor for driving the roller brush to rotate, a liquid spraying assembly, a sewage suction port, a sewage suction channel and a sewage tank, and the sewage suction port is connected to the sewage tank through the sewage suction channel; the cleaning equipment can drive the roller brush to clean the dirty liquid and dirt on the ground through the driving motor, and absorb the dirty liquid and dirt on the ground through the sewage suction port, and the absorbed dirty liquid and dirt enter the sewage suction channel through the sewage suction port, and then enter the sewage tank through the sewage suction channel.

[0034] As shown in Figure 4, the base station includes a base 2, and a water collecting tank 21 is provided in the base 2. When the sewage tank of the cleaning equipment is full of sewage, the user can place the cleaning equipment on the base 2, and then trigger the cover assembly 11 to open the sewage outlet 115 to discharge the sewage in the sewage tank into the water collecting tank 21. In this way, the user does not need to remove the sewage tank from the cleaning equipment to dump the sewage, thereby improving the user experience and making it easier for the user to use the cleaning equipment.

[0035] In order to prevent the user from accidentally opening the cover 111 at the sewage outlet 115 of the sewage tank when the user does not discharge the sewage liquid in the sewage tank, as shown in Figures 1 and 2, an embodiment of the present application provides a sewage tank, including a box body 10. The shape of the box body 10 can be a cylinder, a rectangular parallelepiped, etc. This embodiment does not strictly limit the shape of the box body 10.

[0036] A sewage outlet 115 is provided on the box body 10, and a cover assembly 11 and a locking assembly 12 are provided at the sewage outlet 115; the locking assembly 12 can move between a first position and a second position, wherein when the locking assembly 12 moves from the first position to the second position, the locking assembly 12 locks the cover assembly 11; when the locking assembly 12 moves from the second position to the first position, the locking assembly 12 unlocks the cover assembly 11.

[0037] In a specific application, when the user does not discharge the dirty liquid in the sewage tank, the locking assembly 12 is in the second position to lock the cover assembly 11 at the sewage outlet 115 of the box body 10, thereby preventing the cover assembly 11 of the sewage tank from being accidentally triggered, which may cause the dirty liquid and dirt in the sewage tank to accidentally flow out, which is beneficial to the user's use of the cleaning equipment and improves the user experience.

[0038] When the user needs to discharge the sewage liquid in the sewage tank, the locking assembly 12 can be moved from the second position to the first position to release the lock of the cover assembly 11, so that the user can trigger the cover assembly 11 to open the sewage outlet 115 to discharge the sewage liquid in the sewage tank.

[0039] In order to facilitate the operation of unlocking the cover assembly 11 by the locking assembly 12, as shown in Figure 4, an unlocking structure 22 is provided on the water collecting tank 21 of the base station. When the user places the cleaning equipment on the base station, the sewage tank of the cleaning equipment is also placed on the water collecting tank 21. In this way, the unlocking structure 22 on the water collecting tank 21 can move the locking assembly 12 of the sewage tank from the second position to the first position, so that the locking assembly 12 unlocks the cover assembly 11 of the sewage tank, so that the sewage in the sewage tank can be discharged into the water collecting tank 21. Therefore, the locking assembly 12 can unlock the cover assembly 11 through the unlocking structure 22 on the water collecting tank 21, without the need for the user to perform an unlocking operation, thereby improving convenience.

[0040] Furthermore, as shown in Figures 1 to 3, the cover assembly 11 includes a cover 111, a trigger mechanism 113 and a clamping mechanism 114; the cover 111 is rotatably connected to the area near the sewage outlet 115 on the box body 10, and the trigger mechanism 113 and the clamping mechanism 114 can be movably arranged near the sewage outlet 115; the clamping mechanism 114 is at least partially clamped with the cover 111 to put the cover 111 in a locked state; the trigger mechanism 113 is at least partially abutted against the clamping mechanism 114, and the trigger mechanism 113 is used to move the clamping mechanism 114 in a direction away from the cover 111 to switch the cover 111 from a locked state to an unlocked state.

[0041] The size of the cover plate 111 is slightly larger than the size of the sewage outlet 115 , thereby improving the sealing performance of the cover plate 111 in shielding the sewage outlet 115 .

[0042] When the engaging mechanism 114 is engaged with the cover 111, the cover 111 is locked, that is, the cover 111 is closed, i.e., the cover 111 blocks the drain outlet 115. When the trigger mechanism 113 drives the engaging mechanism 114 to move away from the cover 111, the cover 111 switches from the locked state to the unlocked state, i.e., the cover 111 switches from the closed state to the open state, i.e., the cover 111 no longer blocks the drain outlet 115.

[0043] In specific applications, when the user needs to open the cover 111, the user can apply external force to the trigger mechanism 113 by pressing the trigger mechanism 113, etc., so that the trigger mechanism 113 pushes the clamping mechanism 114 to move in a direction away from the cover 111, thereby separating the clamping structure from the cover 111, so that the cover 111 can rotate downward around the connection with the sewage outlet 115, that is, the cover 111 switches from a locked state to an unlocked state, that is, the cover 111 switches from a closed state to an open state, so that the sewage in the sewage tank flows from the sewage outlet 115 into the water collecting tank 21, so that the user can open the cover 111 by applying external force to the trigger mechanism 113, thereby facilitating the user's operation and improving the user experience.

[0044] When the user needs to close the cover 111 , the user pushes the cover 111 toward the drain outlet 115 until the engaging mechanism 114 engages with the cover 111 .

[0045] Furthermore, as shown in Figures 1 to 3, the clamping mechanism 114 includes a clamping plate 1141 and a first elastic component 1143; a connecting component 1144 is provided on the outside of the box body 10; the clamping plate 1141 is connected to the connecting component 1144 through the first elastic component 1143, the top of the clamping plate 1141 is rotatably connected to the box body 10, and the bottom of the clamping plate 1141 is provided with a hook 1142 for clamping the cover plate 111.

[0046] The first elastic component 1143 may be a spring or other component, and the connecting component 1144 may be a fixed column or other structure.

[0047] When the trigger mechanism 113 is pushed by the external force applied by the user and the card plate 1141 is pushed, the card plate 1141 moves around the connection between it and the box body 10 and in the direction away from the cover plate 111, thereby separating the snap-fit ​​structure from the cover plate 111, so that the cover plate 111 can be rotated downward around the connection between it and the sewage outlet 115 (that is, in the direction of the solid arrow in Figure 1), that is, the cover plate 111 is switched from a closed state to an open state.

[0048] When the cover 111 is opened, the user no longer applies external force to the trigger mechanism 113 , and the clamping plate 1141 returns to its original position due to the contraction force of the first elastic component 1143 .

[0049] When the user pushes the cover 111 to rotate in the direction close to the sewage outlet 115 (i.e., in the direction opposite to the direction of the solid arrow in Figure 1) to the hook 1142 of the card plate 1141, the cover 111 applies a force to the hook 1142, so that the hook 1142 moves in the direction away from the cover 111. When the cover 111 rotates to above the hook 1142, the contraction force of the first elastic component 1143 causes the card plate 1141 to return to its original position again, so that the hook 1142 also returns to its original position with the card plate 1141, thereby locking the cover 111 and putting the cover 111 in a closed state, thereby achieving the purpose of sealing the sewage outlet 115.

[0050] In this embodiment, the opening and closing operations of the cover 111 can be achieved more conveniently and quickly through the cooperation between the first elastic component 1143 and the clamping plate 1141 .

[0051] Furthermore, as shown in FIG. 1 to FIG. 3 , the trigger mechanism 113 includes a support plate 1132 , one end of the support plate 1132 abuts against the clamping plate 1141 , and the other end of the support plate 1132 is provided with a pressing block 1131 .

[0052] The user presses the button 1131, and then drives the support plate 1132 to apply a pushing force to the card plate 1141 through the button 1131, so that the card plate 1141 moves away from the cover plate 111, and drives the hook 1142 of the card plate 1141 to move away from the cover plate 111, so that the hook 1142 is separated from the cover plate 111, and the cover plate 111 is opened.

[0053] In this embodiment, the user can open the cover 111 by pressing the button 1131, which improves the user experience and makes it easier for the user to drain the sewage tank.

[0054] Furthermore, as shown in Figures 1 to 3, the locking assembly 12 includes a slidable slider 122, a sliding groove is provided on the side of the card plate 1141 away from the cover plate 111, the slider 122 is located in the sliding groove, and a second elastic component 121 is provided between the slider 122 and the top wall of the sliding groove.

[0055] Among them, the second elastic component 121 is used to push the slider 122 from the first position to the second position, and the first elastic component 1143 can be a spring or other components; the position where the slider 122 avoids the card plate 1141 is the first position, and the position where the slider 122 and the card plate 1141 are relative to each other is the second position.

[0056] When the user does not drain the sewage tank, that is, when the cleaning device is not placed on the base station, the second elastic component 121 is at its natural length, thereby pushing the slider 122 to slide from the first position to the second position, that is, the slider 122 slides from the position avoiding the card plate 1141 to the position opposite to the card plate 1141. In this way, even if the button 1131 is subjected to a force and applies a thrust to the card plate 1141 through the support plate 1132, the slider 122 can prevent the card plate 1141 from rotating away from the cover plate 111 due to the thrust of the support plate 1132, thereby achieving the purpose of locking.

[0057] In this embodiment, the clamping plate 1141 can be locked by the cooperation between the second elastic component 121 and the slider 122 , which has a simple structure, is easy to manufacture and easy to implement.

[0058] As shown in Figure 1, when the user places the cleaning equipment on the base station, the sewage tank of the cleaning equipment is also placed on the water collecting tank 21, so that the unlocking structure 22 on the water collecting tank 21 can enable the slider 122 to move from the second position to the first position (that is, the direction of the dotted arrow in Figure 1), that is, the slider 122 slides from the position opposite to the card plate 1141 to the position avoiding the card plate 1141. In this way, when the pressing block 1131 is subjected to the force and applies a thrust to the card plate 1141 through the support plate 1132, the slider 122 cannot prevent the card plate 1141 from rotating in the direction away from the cover plate 111 due to the thrust of the support plate 1132, thereby achieving the purpose of unlocking.

[0059] Specifically, as shown in Figure 4, the unlocking structure 22 on the water collecting tank 21 includes an unlocking rod 221 extending upward. The slider 122 is lifted by the unlocking rod 221, and the slider 122 moves from the second position to the first position, and compresses the second elastic component 121. Thus, the locking plate 1141 can be released by the cooperation between the unlocking rod 221 and the slider 122. The structure is simple, easy to manufacture and easy to implement.

[0060] In one implementation, there are two unlocking rods 221, which are spaced apart so that the two unlocking rods 221 can push both ends of the slider 122 at the same time, thereby causing both ends of the slider 122 to move simultaneously to ensure that the slider 122 can move as a whole from the second position to the first position.

[0061] Furthermore, as shown in Figures 1 to 3, a third elastic member 112 is provided at the connection between the cover plate 111 and the edge of the drain outlet 115. After the hook 1142 of the latch 1141 disengages from the cover plate 111, the torsional force of the third elastic member 112 can cause the cover plate 111 to rotate downward rapidly, thereby increasing the speed at which the cover plate 111 opens. The third elastic member 112 can be a torsion spring, and the torsion force provided by the torsion spring can cause the cover plate 111 to open rapidly.

[0062] Furthermore, as shown in FIG1 and FIG2, the sewage outlet 115 is located at the bottom of the box body 10, so that after the cover 111 is opened, the sewage can flow into the water collecting tank 21 by gravity, eliminating other pumping components and reducing costs.

[0063] The present application has been described through the above-described embodiments, but it should be understood that the above-described embodiments are for illustrative and illustrative purposes only and are not intended to limit the present application to the described embodiments. In addition, it will be understood by those skilled in the art that the present application is not limited to the above-described embodiments, and that various variations and modifications may be made based on the teachings of the present application, all of which fall within the scope of protection claimed in the present application.
