[0028] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0029] A water tank is installed on the base station that is equipped with cleaning equipment such as floor scrubbers. The dry and wet garbage in the cleaning equipment is transferred to the water tank on the base station through the negative pressure of the fan on the base station for storage. When the sewage capacity in the water tank reaches the limited volume, trigger protection is required to prevent the risk of excessive water causing water tank overflow, water ingress to the fan and other components to be damaged.

[0030] In related technologies, the water level detection components in the water tank mostly adopt a float structure. However, in the process of discharging and dumping the sewage in the water tank, garbage in the sewage is likely to hang on the float. On the one hand, it is not conducive to user cleaning. On the other hand, when garbage sticks to the float, it will affect the weight of the float, causing the float to be unable to float to the specified position when the preset water volume position is reached, resulting in errors in triggering protection, affecting the detection of sewage capacity and component protection functions.

[0031] Based on the above technical issues, the present application provides a tank cover assembly, a water tank, a base station, and a cleaning system, which are intended to at least partially address the technical issue of inaccurate protection triggering when the sewage volume in the water tank reaches a specified volume, thereby preventing the impact on sewage volume detection and component protection functions. The following describes specific implementations of the present application with reference to the accompanying drawings.

[0032] Figure 1 This is a schematic diagram of the water tank described in some embodiments of this application. Figure 2 for Figure 1 The exploded view of the water tank is as follows: Figure 1 as well as Figure 2 As shown, the water tank includes a lid 100 and a body 200. The lid 100 is connected to the body 200 via a pivot structure, allowing the user to open the lid 100 by flipping it upward. In another embodiment, the lid 100 can also be inserted into the drain outlet 201 of the water tank, allowing the user to open the drain outlet 201 by inserting and removing the lid 100.

[0033] Figure 3 for Figure 1 The structural diagram of the box cover assembly. Figure 2 and Figure 3 The water tank body 200 is provided with a sewage outlet 201, and the tank cover assembly 100 includes a cover body 101 and a water level detection assembly 102. The cover body 101 is at least partially detachably connected to the sewage outlet 201 of the tank body 200. The cover body 101 can be buckled into the sewage outlet 201 of the tank body 200, and the water level detection assembly 102 is arranged on the cover body 101.

[0034] The box cover assembly 100 provided in the present application has a water level detection assembly 102 for detecting the sewage capacity in the box body 200 of the water tank, which is arranged on the cover body 101. In the process of discharging the sewage in the box body 200 through the sewage outlet 201 of the box body 200, the water level detection assembly 102 is opened together with the cover body 101, and does not come into contact with the sewage, so as to avoid garbage in the sewage hanging on the water level detection assembly 102 and affecting the triggering accuracy of the water level detection assembly 102. The detection error of the water level detection assembly 102 can be avoided to a certain extent, so as to ensure the sewage capacity detection accuracy and protect components, and has good practicality.

[0035] Combine Figure 3 The water level detection component 102 can adopt a float structure to drive the float structure according to the capacity of the sewage in the water tank, so as to generate a trigger signal when the water level in the water tank reaches a limited volume. Figure 3 -Attached Figure 10 The specific structure and assembly method of the water level detection component 102 are further described in detail.

[0036] Figure 4 for Figure 3 Schematic diagram of the structure of the water level detection component in . Figure 4 The water level detection assembly 102 includes a cantilever 1021, a floating member 1022, and a trigger member 1023. The cantilever 1021 is rotatably connected to the cover 101 via a rotating shaft 104. The floating member 1022 and the trigger member 1023 are respectively disposed at both ends of the cantilever 1021. When the tank cover assembly 100 is fastened to the sewage outlet 201 of the water tank, the floating member 1022 descends into the tank body 200 due to gravity. The trigger member 1023 is located above the floating member 1022. When the sewage level in the tank body 200 rises, the floating member 1022 rises along with the sewage level it contacts due to buoyancy, thereby driving the cantilever 1021 to rotate about the rotating shaft 104, causing the trigger member 1023 to rotate as well. The trigger member 1023 is at least partially magnetic to trigger the Hall element that cooperates with the trigger member 1023, so that when the water level in the water tank reaches a preset value, the Hall element generates a water full signal to detect the water level in the water tank. The Hall element can be set outside the water tank or inside the water tank, and this application does not impose any restrictions on this.

[0037] Figure 5 for Figure 3 The structural diagram of the cover 101 is shown. Figure 4 as well as Figure 5 The side of the cover 101 facing the box body 200 is defined as the inner side of the cover 101. Two opposing brackets 103 are provided on the inner side of the cover 101. The cantilever 1021 is rotatably connected between the two brackets 103 via a rotating shaft 104. In one embodiment, the two brackets 103 can be triangular, trapezoidal, or other shapes, and are connected to the inner side of the cover 101 by integral molding or snap-fitting. Figure 4 The rotating shaft 104 shown is connected to the bottom end of each of the two brackets 103. Figure 4 The trigger member 1023 shown provides sufficient rotation space. In another embodiment, if the rotation space of the trigger member 1023 is sufficient, the rotating shaft 104 can also be connected to the middle of each of the two brackets 103, and this application does not limit this.

[0038] Combine Figure 4 as well as Figure 5In one embodiment, the cantilever 1021 may be a plate-like structure, and the cantilever 1021 is provided with a through hole 1024, and the rotating shaft 104 is movably provided in the through hole 1024. At least one end of the rotating shaft 104 may be connected to at least one of the two brackets 103. In one embodiment, the rotating shaft 104 may be fixedly connected to at least one of the two brackets 103 by means of threads or the like, or may rotate between the two brackets 103. A gap is provided between the cantilever 1021 and the two brackets 103 so that the cantilever 1021 can rotate around the rotating shaft 104. The gap setting means that the cantilever 1021 has a certain distance from the two brackets 103 to avoid contact between the cantilever 1021 and the two brackets 103 during rotation, so that the cantilever 1021 rotates smoothly.

[0039] Figure 6 for Figure 4 The exploded diagram of the water level detection assembly. Figure 4 and Figure 6 The cantilever 1021 includes a trigger end 1025 and a driving end 1026. The trigger member 1023 is set on the trigger end 1025 of the cantilever 1021. The floating member 1022 is set to be connected to the driving end 1026 of the cantilever 1021. The weight of the floating member 1022 is greater than the weight of the trigger member 1023. When there is no sewage in the water tank body 200, the floating member 1022 can be used to hang in the water tank body 200 by utilizing its own weight.

[0040] Specifically, if Figure 6 As shown, the floating member 1022 includes a float 1022a and a configuration block 1022b. The float 1022a is connected to the driving end 1026 of the cantilever 1021. The configuration block 1022b is disposed within the float 1022a. The configuration block 1022b is heavier than the trigger 1023, thereby balancing the weight of the floating member 1022 and the weight of the trigger 1023. This balances the weight of the trigger 1023 and the suction force of the fan (not shown). In a specific implementation, the float 1022a can be configured as a columnar structure with a positioning cavity 1022c formed therein that matches the shape of the configuration block 1022b. The configuration block 1022b is assembled within the positioning cavity 1022c. An openable cover 1022d is provided at one axial end of the float 1022a. The cover 1022d can be threaded, fitted, or snap-fitted onto the end of the float 1022a to facilitate assembly of the configuration block 1022b within the float 1022a. In one embodiment, the cover 1022d is integrally formed using an ultrasonic process to ensure a good seal and waterproofing when the cover 1022d seals against the float 1022a. In other embodiments, the float 1022a may also have a spherical or other structural form, which is not limited in this application.

[0041] Combine Figure 4 and Figure 6 The trigger end 1025 of the cantilever 1021 is provided with a mounting cavity 1027. The mounting cavity 1027 includes an assembly opening 1027a, which accommodates the trigger element 1023, which is made of a magnet, with an interference fit. In one embodiment, the assembly opening 1027a of the mounting cavity 1027 is located at the top of the mounting cavity 1027 to prevent wastewater in the water tank from entering the mounting cavity 1027. Furthermore, the provision of the assembly opening 1027a reduces signal transmission obstacles between the trigger element 1023 and the Hall element, thereby improving the sensitivity of the triggering between the trigger element 1023 and the Hall element.

[0042] Figure 7 for Figure 1 The structural diagram of the box 200. Figure 6 as well as Figure 7 The water level detection assembly 102 also includes a seal 105, which is used to block the air extraction port 202 on the tank 200. When the sewage level in the water tank does not reach a preset value, or the sewage capacity does not reach a set capacity, a gap exists between the seal 105 and the air extraction port 202 of the tank 200, preventing the air extraction port 202 from being blocked. A fan (not shown) generates negative pressure in the tank 200, thereby transferring the dry and wet waste in the cleaning equipment to the water tank on the base station. When the sewage level in the water tank reaches a preset value, or the sewage capacity reaches a set capacity, the sealing member 105 rotates along with the raising trigger member 1023, blocking (sealing) the air suction port 202 of the box body 200, so that the sewage in the box body 200 cannot flow out through the air suction port 202, the fan will not affect the operation of the box body 200, and the dry and wet garbage in the cleaning equipment will not be transferred to the water tank on the base station. This avoids the phenomenon that the sewage in the water tank overflows through the opened air suction port 202 and enters the fan or other components when the water level detection fails, thereby protecting the normal operation of the fan and other components.

[0043] Figure 8 for Figure 6 The schematic structural diagram of the cantilever, Figure 9 for Figure 6 The structural diagram of the sealing member is shown in FIG. Figure 8 and Figure 9 , the seal 105 is connected to the trigger end 1025 of the cantilever 1021, Figure 4The trigger member 1023 is shown disposed at the top of the cantilever 1021, and the seal 105 is disposed at the bottom of the cantilever 1021. In a specific embodiment, a connecting block 106 is disposed at the bottom of the trigger end 1025 of the cantilever 1021. The connecting block 106 may be provided with a convex portion 1061 on its circumference. The seal 105 may be an annular structure with a concave portion 1051 disposed on its inner side, so that the seal 105 is sleeved on the circumference of the connecting block 106 with an interference fit. The convex portion 1061 on the circumference of the connecting block 106 is embedded in the concave portion 1051 of the seal 105, thereby stably and securely assembling the seal 105 to the connecting block 106.

[0044] Furthermore, if the rotation angle of the cantilever 1021 is too small, the rotation range of the trigger end 1025 of the cantilever 1021 will also be too small, which may not only cause accidental touches, but also may cause the seal 105 to be sucked to the air outlet 202 of the box 200 by the action of the fan. Based on this, the present application sets the rotation angle of the cantilever 1021 to 0-80 degrees, that is, the cantilever 1021 can rotate around the rotation axis 104 at an angle less than or equal to 80 degrees, for example, 30 degrees, 40 degrees, or 80 degrees, to ensure that the trigger end 1025 of the cantilever 1021 has sufficient rotation range to avoid accidental touches and prevent the seal 105 from being sucked to the air outlet 202 of the box 200 by the fan.

[0045] Specifically, the cantilever 1021 of the present application has a first and second extreme rotation positions. The first extreme position is the trigger position of the trigger member 1023. When the trigger member 1023 is in a horizontal position, its performance in triggering the Hall element to generate a trigger signal is optimal. The second extreme position is the maximum extreme position at which the trigger member 1023 rotates about the rotation axis 104 under the weight of the floating member 1022 when there is no sewage in the tank 200 or the sewage does not contact the floating member 1022. At this point, the distance between the trigger member 1023 and the Hall element is the farthest, and the floating member 1022 is positioned within the tank body 200.

[0046] Combine Figure 6 as well as Figure 7In order to keep the cantilever 1021 in the first extreme position, a first stopper 107 is further provided on the water tank to limit the rotation of the cantilever 1021. In one embodiment, the first stopper 107 can reuse the air inlet 202 of the box body 200. When the cantilever 1021 is in the first extreme position, the sealing member 105 on the cantilever 1021 abuts against the air inlet 202 of the box body 200, which not only seals the air inlet 202 of the box body 200 but also limits the rotation of the cantilever 1021, so that the cantilever 1021 remains in the first extreme position. In another embodiment, the first stopper 107 can also be provided on the cover body 101. When the cantilever 1021 is in the first extreme position, the first stopper 107 can be supported by the bottom of the cantilever 1021. The first stopper 107 can be a block-shaped structure connected to the bottom of the cover body 101, so that the cantilever 1021 remains in the first extreme position.

[0047] Combine Figure 5 Similarly, to keep the cantilever 1021 at the second limit position, a second stopper 108 is further provided on the cover body 101 of the cover assembly 100 to limit the rotation of the cantilever 1021. The second stopper 108 can be a block-shaped structure provided on the cover body 101 and positioned between the two brackets 103. When the cantilever 1021 is at the second limit position, the second stopper 108 can be supported on the top of the cantilever 1021 to keep the cantilever 1021 at the second limit position.

[0048] Figure 10 for Figure 8 A side view of the cantilever. Figure 10 The trigger member 1023 has a first linear distance L1 to the rotating shaft 104, and the floating member 1022 has a second linear distance L2 to the rotating shaft 104. The first linear distance L1 is smaller than the second linear distance L2, so as to utilize the lever principle to realize the rotation of the cantilever 1021. In addition, since the second linear distance L2 is greater than the first linear distance L1, it is equivalent to lengthening the Figure 6 The torque of the driving end 1026 of the cantilever 1021 shown helps reduce the buoyancy required by the float 1022, thereby reducing its volume and preventing it from colliding with the tank 200 as the lid 101 moves. This also helps reduce the surface area of ​​the float 1022, reducing the likelihood of it becoming attached to trash. Furthermore, the lengthened swing arm of the float ball 1022a of the cantilever 1021 increases the rotational distance of the float 1022 while maintaining the same rotation angle of the cantilever 1021, thereby improving water level detection accuracy. In a specific implementation, the ratio of the first distance L1 to the second distance L2 is between 1:1.5 and 1:3, preferably between 1:2.

[0049] To sum up, the box cover assembly 100 provided in the present application, during the process of discharging the sewage in the box body 200 through the sewage outlet 201 of the box body 200, the water level detection assembly 102 is installed on the inner side of the box cover assembly 100, and the box cover assembly 100 is separated from the box body 200, so that the water level detection assembly 102 will not come into contact with the sewage, which can prevent garbage in the sewage from hanging on the water level detection assembly 102, thereby improving the triggering accuracy of the water level detection assembly 102, and when the sewage in the water tank reaches the set capacity, the seal 105 on the water level detection assembly 102 can seal the air outlet 202 of the water tank to protect components such as the fan, and has good practicality.

[0050] In the second aspect of the present application, the present application also provides a water tank, which includes a tank body 200 and the above-mentioned tank cover assembly 100, wherein the tank body 200 is provided with a sewage outlet 201, the cover body 101 of the above-mentioned tank cover assembly 100 is connected to the sewage outlet 201 of the tank body 200, and the water level detection assembly 102 is arranged on the side of the cover body 101 facing the interior of the tank body 200.

[0051] The water tank provided in the present application can avoid the triggering error of the water level detection component 102 in the water tank to a certain extent, so as to ensure the functions of sewage capacity detection and component protection, and has good practicality.

[0052] Combine Figure 7 A docking portion 204 is provided on the outside of the top of the box body 200. The docking portion 204 can be a raised structure protruding from the outside of the box body 200. A sewage inlet 203 and the above-mentioned air extraction port 202 are provided on the docking portion 204 at intervals. The sewage inlet 203 is suitable for connecting with an external cleaning device, and the air extraction port 202 is suitable for connecting with a fan. In specific implementation, after the cleaning device is docked with the docking portion 204, under the action of the fan, the air in the water tank is discharged through the air extraction port 202, so that a negative pressure is formed inside the water tank, and the dry and wet garbage in the cleaning device is transferred to the water tank on the base station through the sewage inlet 203. When the sewage capacity in the water tank reaches a limited volume, the trigger component 1023 of the water level detection component 102 triggers the Hall element to generate a water full signal, and then controls the fan to stop working, and the dry and wet garbage in the cleaning device stops being output to the water tank on the base station. At the same time, the seal 105 of the water level detection component 102 seals the air exhaust port 202 on the box body 200, preventing the sewage in the water tank from overflowing through the open air exhaust port 202 and entering into the fan, including but not limited to the fan, when the water level detection fails, to protect the fan and other components.

[0053] Combine Figure 7The air extraction port 202 in this application is arranged above the sewage inlet 203, that is, the air extraction port 202 is higher than the sewage inlet 203, so as to prevent the sewage from overflowing through the opened air extraction port 202 and entering into the fan, including but not limited to the fan, during the process of entering the box body 200 from the sewage inlet 203, so as to protect the fan and other components.

[0055] The base station provided in the present application can avoid the triggering error of the water level detection component 102 in the water tank to a certain extent, so as to ensure the detection of sewage capacity and the protection of components, and has good practicality.
