[0002] With technological advancements, cleaning equipment has emerged for cleaning surfaces and other objects. This equipment utilizes an internal water tank to support its cleaning function. However, current technologies typically only detect water shortages in the clean water tank (whether it's below the minimum water level) and fullness in the wastewater tank (whether it's above the maximum water level). But when performing a cleaning task, the required water level may exceed the minimum level, preventing the task from being completed and impacting efficiency. Utility Model Content

[0003] Therefore, the present invention aims to solve the technical problem of the inability to obtain the remaining water volume of the cleaning base station of the cleaning equipment in real time, which affects the working efficiency of the cleaning equipment.

[0004] To solve the above-mentioned technical problems, this utility model provides a clean base station, comprising:

[0005] A water tank assembly is detachably installed on the cleaning base station;

[0006] A first liquid level detection component is disposed inside the water tank assembly. The first liquid level detection component includes a floating component and a magnetic component. The floating component floats as the liquid level in the water tank assembly rises or falls. The magnetic component rotates as the floating component floats.

[0007] The second liquid level detection component is installed on the cleaning base station and is used to detect the magnetic information of the magnetic component when the water tank component is installed in the cleaning base station.

[0008] A processing component is used to determine the liquid level change within the water tank assembly based on the magnetic information transmitted by the second liquid level detection component.

[0009] Optionally, the floating assembly includes a floating part, a magnetic component part, and a rotating shaft structure; one end of the floating part floats with the rise and fall of the liquid level in the water tank assembly; the other end of the floating part is connected to the magnetic component part and the rotating shaft structure; a magnetic component is provided inside the magnetic component part.

[0010] Optionally, the floating part includes a connecting rod and a floating component. The floating component is disposed at one end of the connecting rod and floats as the liquid level in the water tank assembly rises and falls. The other end of the connecting rod is connected to the magnetic component and the rotating shaft structure.

[0011] Optionally, the second liquid level detection component is a magnetic sensor, which is used to detect the magnetic information generated by the magnetic component.

[0012] Optionally, the second liquid level detection component is installed on the same axis as the magnetic component inside the water tank assembly.

[0013] Optionally, the magnetic assembly has a mounting position configured to allow the magnetic assembly to be mounted in at least two orientations.

[0014] Optionally, the magnetic assembly is installed in a positive orientation or a negative orientation.

[0015] Optionally, the processing unit is configured to determine the magnet movement angle based on the magnetic information to determine the liquid level change; the installation angle difference between the magnetic assembly installed in the positive orientation and the negative orientation is 180 degrees, and when the magnetic assembly is installed in the negative orientation, the processing unit is configured to output the same magnet movement angle as when the magnetic assembly is installed in the positive orientation.

[0017] This utility model also provides a cleaning system, including a cleaning robot and the aforementioned cleaning base station.

[0018] The technical solution provided by this utility model has the following advantages:

[0019] In the cleaning base station provided by this utility model, the water tank assembly is detachably installed in the cleaning base station, and a first liquid level detection assembly is set in the water tank assembly. The first liquid level detection assembly includes a floating assembly and a magnetic assembly. The floating assembly can float with the rise and fall of the liquid level in the water tank assembly, and the magnetic assembly can rotate with the floating assembly, causing the magnetic field in the water tank assembly to change. When the water tank assembly is installed in the cleaning base station, the second liquid level detection component installed on the cleaning base station can detect changes in the magnetic field and obtain magnetic information. It can also transmit the detected magnetic field information to the processing unit in a timely manner. The processing unit confirms the foolproof signal based on the magnetic field information, thereby determining a relatively accurate real-time liquid level height of the water tank assembly. The cleaning base station can determine whether the liquid level in the water tank assembly meets the minimum liquid level requirement of the cleaning task based on the liquid level required for the current cleaning task. If it is determined that the real-time liquid level of the water tank assembly meets the cleaning task but is close to the minimum liquid level requirement, it will output a prompt to add cleaning liquid in a timely manner to achieve an early warning effect of liquid level. If it is determined that the current real-time liquid level does not meet the minimum liquid level requirement, it will switch to water-saving mode in a timely manner, or adjust the cleaning task based on the real-time liquid level, thereby improving the execution efficiency of the cleaning task.

[0030] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0031] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0032] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0033] Please see Figures 1 to 3This embodiment provides a cleaning base station 100 and a cleaning system including the cleaning base station 100 and a cleaning robot. Specifically, the cleaning robot and the cleaning base station 100 in the cleaning system work together to handle cleaning tasks, such as cleaning an area to be cleaned. The cleaning robot may be equipped with a wet cleaning component, which cleans the surface of the area to be cleaned. The cleaning base station can clean the wet cleaning component on the cleaning robot and replenish the cleaning robot with cleaning liquid through a water tank assembly within the cleaning base station. Optionally, the wet cleaning component may be a disc-shaped wiping assembly, a tracked wiping assembly, etc. The water tank assembly 1 within the cleaning base station 100 can provide cleaning liquid for cleaning. During the cleaning process, the liquid level in the water tank assembly 1 changes continuously, and the floating component 21 of the first liquid level detection component 2 within the water tank assembly 1 also floats with the change in the liquid level. The floating of the floating component 21 will drive the rotation of the magnetic component 22 connected to the floating component 21. Thus, the rotation of the magnetic component 22 will cause a change in the magnetic field within the water tank assembly 1. Correspondingly, the second liquid level detection component 3 on the cleaning base station 100 can detect changes in the magnetic field information in the water tank component 1 in real time, that is, acquire the magnetic information and transmit the magnetic information to the processing component (not shown in the figure) in a timely manner. Based on this, the processing component can process the magnetic information, determine the real-time liquid level change of the cleaning liquid in the water tank component 1, ensure the timeliness of liquid level detection, and also adjust the cleaning task in a timely manner based on the liquid level change to improve the execution efficiency of the cleaning task.

[0034] See Figures 1 to 2 This embodiment provides a cleaning base station 100 (partial structure), which includes a water tank assembly 1, a first liquid level detection assembly 2, a second liquid level detection assembly 3, and a processing component.

[0035] The water tank assembly 1 is detachably installed in the cleaning base station 100; the first liquid level detection assembly 2 is disposed inside the water tank assembly 1, and the first liquid level detection assembly 2 includes a floating assembly 21 and a magnetic assembly 22. The floating assembly 21 floats with the rise and fall of the liquid level in the water tank assembly 1; the magnetic assembly 22 rotates with the floating assembly 21; the second liquid level detection assembly 3 is disposed on the cleaning base station 100, and is used to detect the magnetic information of the magnetic assembly 22 when the water tank assembly 1 is installed in the cleaning base station 100; the processing unit is used to determine the liquid level change in the water tank assembly 1 based on the magnetic information transmitted by the second liquid level detection assembly 3.

[0036] Specifically, the water tank assembly 1 is used to store cleaning liquid, which can be clean water or other cleaning solutions used to perform cleaning tasks. When the water tank assembly 1 is installed in the cleaning base station 100 and contains cleaning liquid, the cleaning base station 100 and the cleaning robot can work together to perform cleaning tasks. In other words, the water tank assembly 1 and the cleaning base station 100 are detachable, and the installation of the water tank assembly 1 in the cleaning base station 100 can be adjusted based on the actual needs of the cleaning task.

[0037] Please continue reading. Figures 1 to 2 The water tank assembly 1 can be equipped with a first liquid level detection assembly 2, which includes a floating assembly 21 and a magnetic assembly 22. The floating assembly 21 will synchronously drive the magnetic assembly 22 to rotate inside the water tank assembly 1 as the liquid level inside the water tank assembly 1 changes. Since the rotation of the magnetic assembly 22 causes a change in the magnetic field, the second liquid level detection assembly 3 on the cleaning base station 100 can detect the magnetic information characterizing the change in the magnetic field. Through the transmission of magnetic information between the second liquid level detection assembly 3 and the processing unit, the processing unit can convert the magnetic information into the corresponding liquid level value, so that the cleaning base station 100 can realize real-time detection of liquid level changes. Specifically, the floating component 21 is connected to the magnetic component 22, enabling the detection of liquid level changes through magnetic information detection. The first liquid level detection component 2 is located in the water tank component 1 and is separate from the second liquid level detection component 3 located on the outer surface of the cleaning base station 100. Information transmission can be achieved between the two liquid level detection components without physical connection, facilitating the disassembly of the water tank component 1. The processing unit can achieve relatively accurate liquid level detection with a lower configuration cost through magnetic information transmission between the second liquid level detection components 3, avoiding interruption of cleaning tasks due to insufficient water level, further improving the processing efficiency of cleaning tasks, simplifying the structural design of the cleaning base station, further reducing the complexity of the cleaning base station 100, improving the dimensionality of the cleaning base station 100, and thus ensuring the user experience.

[0038] Optionally, there are many ways to connect the first liquid level detection component 2 and the water tank component 1. This utility model does not limit the above connection methods. Those skilled in the art can determine the specific connection method based on the actual application scenario.

[0039] In some embodiments, please refer to Figure 3 The floating assembly 21 includes a floating part 211, a magnetic assembly part 212, and a rotating shaft structure 213; one end of the floating part 211 floats with the rise and fall of the liquid level in the water tank assembly 1; the other end of the floating part 211 is connected to the magnetic assembly part 212 and the rotating shaft structure 213; a magnetic assembly 22 is provided inside the magnetic assembly part 212.

[0040] Specifically, when there is no cleaning liquid inside the water tank assembly 1, the float 211 can be located at the bottom of the water tank assembly 1. As the cleaning liquid inside the water tank assembly 1 increases, the liquid level will change accordingly. One end of the float 211 will float in the cleaning liquid due to buoyancy. The other end of the float 211 is connected to the magnetic assembly 212 through the rotating shaft structure 213. The floating of the float 211 will drive the rotating shaft structure 213 to rotate, which in turn will drive the magnetic assembly 22 in the magnetic assembly 212 to rotate. The magnetic assembly 22 is an object with magnetic properties, which will affect the magnetic field inside the water tank assembly 1. The rotation of the magnetic assembly 22 will cause the angle of the magnetic field inside the water tank to change. In this way, the second liquid level detection assembly 3 can detect the analog signal of the angle of the magnetic field inside the cleaning base station 100 and transmit the detected analog signal to the processing unit.

[0041] Optionally, the magnetic component 22 can be a magnet, such as a neodymium magnet, which is a tetragonal crystal formed by neodymium, iron and boron elements, to ensure the sensitivity of the magnetic field angle as the liquid level rises and falls.

[0042] In this embodiment, since the floating part 211 in the floating component 21 can float with the change of liquid level and drive the magnetic component 22 to rotate, the magnetic information inside the water tank component 1 changes, which provides the cleaning base station 100 with the possibility of real-time and accurate detection of liquid level through magnetic information.

[0043] Furthermore, in some embodiments, the floating part 211 can be a multi-ended structure. For example, a floating element can be provided at one end of the floating part 211, and the other end of the floating part 211 can be connected to the floating element through a connecting structure such as a connecting rod. Optionally, this embodiment does not limit the specific material of the floating element; any material that can satisfy the floating performance of the floating element can be selected. Based on this, the specific structure of the floating part 211 can be found below:

[0044] The floating part 211 includes a connecting rod and a floating component. The floating component is disposed at one end of the connecting rod and floats as the liquid level in the water tank assembly 1 rises and falls. The other end of the connecting rod is connected to the magnetic assembly part 212 and the rotating shaft structure 213.

[0045] Specifically, the floating part 211 includes a floating element and a connecting rod. One end of the connecting rod is equipped with the floating element, which floats according to changes in the liquid level within the water tank assembly 1. The other end of the connecting rod is equipped with a rotating shaft structure 213 and a magnetic component 212. That is, the other end of the connecting rod is connected to the magnetic component 212 via the rotating shaft structure 213. A magnetic component 22 can be installed within the magnetic component 212. When the liquid level in the water tank assembly 1 changes up and down, the floating part 211 also floats up and down with the liquid level changes. The connecting rod itself also has buoyancy and floats relative to the water tank assembly 1 along with the floating element. Correspondingly, the magnetic component 22 on the other end of the connecting rod rotates relative to the water tank assembly 1 along with the floating of the connecting rod and the floating element. The second liquid level detection component 3 can detect changes in magnetic information caused by the rotation of the magnetic component 22.

[0046] In some embodiments, the second liquid level detection component 3 is a magnetic sensor, which is used to detect the magnetic information generated by the magnetic component 22.

[0047] Optionally, the magnetic sensor can be a TMR sensor, and the magnetic information can be an analog signal of the angle change of the magnetic field inside the cleaning base station 100. The TMR sensor is used to detect the analog signal corresponding to the angle change of the magnetic field inside the cleaning base station 100. For example, the analog signal detected by the TMR sensor can be a voltage value.

[0048] Specifically, the magnetic component 22 inside the cleaning base station 100 rotates, causing a change in the magnetic field within the cleaning base station 100. The TMR sensor installed on the outer wall of the cleaning base station 100 can detect the change in the angle of the magnetic field in the cleaning base station 100 in real time, obtain an analog signal of the change in the magnetic field angle, and transmit it to the processing unit of the cleaning base station 100. The processing unit can receive the real-time analog signal representing the change in the magnetic field angle and process the analog signal in a timely manner to obtain the real-time liquid level change in the water tank component 1, improving the timeliness of liquid level detection. The cleaning robot can adjust the cleaning task in a timely manner based on the real-time liquid level change. For example, it can prioritize the cleaning task that is more matched to the real-time liquid level. The cleaning robot can also switch to a water-saving mode when the real-time liquid level is low, or output a prompt message to remind the user to fill the water tank component 1 with cleaning liquid, etc., further improving the overall cleaning effect of the cleaning system and the processing efficiency of the cleaning task.

[0049] In some embodiments, please refer to Figures 4 to 5 , Figure 4 This is a side view of the clean base station 100. Figure 5 for Figure 4A cross-sectional view of the AA side. The installation position of the second liquid level detection component 3 is on the same axis as the magnetic component 22 inside the water tank component 1. The second liquid level detection component 3 can better detect the magnetic field changes caused by the rotation of the magnetic component 22, thereby improving the detection accuracy of magnetic information.

[0050] In some embodiments, the magnetic assembly 212 has a mounting position configured to allow the magnetic assembly 22 to be installed in at least two orientations. By providing a mounting position at the mounting location, the installation of the magnetic assembly is facilitated, improving the installation efficiency and flexibility. The processing component can determine the magnet's movement angle, allowing the mounting position to perform foolproof processing without the need for a dedicated foolproof structure.

[0051] Optionally, the magnetic assembly 22 can be installed in a positive orientation or a negative orientation.

[0052] Specifically, the magnetic component 22 is installed in a positive orientation, with an installation angle of 0-180 degrees; the magnetic component 22 is installed in a negative orientation, with an installation angle of 180-360 degrees. In other words, the positive and negative orientations refer to the direction in which the magnetic component 22 is mounted on the mounting position of the magnetic component section 212. The installation orientation is related to the direction in which the magnetic field passes through the second liquid level detection component 3. The magnetic field refers to the magnetic field generated by the magnetic component 22 inside the cleaning base station 100. When the magnetic component 22 is installed in a positive orientation, the direction in which the magnetic field passes through the second liquid level detection component 3 can be from the N pole to the S pole; when the magnetic component 22 is installed in a negative orientation, the direction in which the magnetic field passes through the second liquid level detection component 3 can be from the S pole to the N pole.

[0053] Optionally, the specific process of the processing component performing the error prevention process may include: the processing component being configured to determine the magnet's motion range value based on magnetic information, the magnet's motion range value being 0-360 degrees; and determining the magnet's motion angle based on the magnet's motion range value and the attitude of the magnetic component 22, the motion angle being 0-180 degrees.

[0054] Here, magnetic information refers to the analog signal corresponding to the change in magnetic field angle. The attitude of magnetic component 22 refers to the mounting attitude of magnetic component 22 on the mounting position on magnetic component section 212, including either positive or negative mounting. Optionally, the magnetic information output by the second liquid level detection component can be the voltage value corresponding to the magnetic field angle.

[0055] Specifically, the second liquid level detection component 3 includes a communication component, and the processing component is wirelessly and / or wiredly connected to the second liquid level detection component 3 via the communication component. When the processing component and the second liquid level detection component are wirelessly connected, magnetic information can be transmitted from the second liquid level detection component to the processing component. In this way, the processing component can read the analog signal output by the second liquid level detection component and, according to a preset correlation between the analog signal and the angle, calculate the initial angle corresponding to the current analog signal output by the second liquid level detection component, i.e., the magnet's movement range value. Since the magnetic component 22 can be installed in a forward or reverse orientation, different installation orientations correspond to different processes for determining the magnet's movement angle. This embodiment does not limit the connection method between the processing component and the second liquid level detection component 3; those skilled in the art can determine the specific connection method based on the actual application scenario.

[0056] One possible implementation is that after determining the magnet's motion range value, the processing component can determine the installation posture of the magnetic component 22. If the magnetic component 22 is determined to be installed in a positive posture, the magnet's motion range value can be determined as the magnet's motion angle. If the magnetic component 22 is determined to be installed in a negative posture, the difference between the magnet's motion range value and the target angle can be calculated, and the absolute value of the difference can be determined as the magnet's motion angle.

[0057] Optionally, if the processing unit determines that the magnet's range of motion is within a first angle range, it can determine that the magnetic component 22 is in a positive orientation; correspondingly, if the processing unit determines that the magnet's range of motion is within a second angle range, it can determine that the magnetic component 22 is in a negative orientation.

[0058] Another possible implementation is that, after determining the magnet's range of motion value, the processing unit can determine the angular range to which that range of motion value belongs, and based on that angular range and the magnet's range of motion value, obtain the magnet's motion angle. For example, if the processing unit determines that the magnet's range of motion value belongs to a first angular range, then the magnet's range of motion value can be determined as the magnet's motion angle; if the processing unit determines that the magnet's range of motion value belongs to a second angular range, then the difference between the magnet's range of motion value and the target angle is calculated, and the absolute value of the difference is determined as the magnet's motion angle.

[0059] The target angle can be 180 degrees, the first angle range can be 0-180 degrees, and the second angle range can be 180 degrees-360 degrees.

[0060] Another possible implementation is as follows: For example, when there is no water in the water tank assembly 1, the floating assembly 21 is at the bottom of the water tank assembly 1, and the magnetic field angle of the cleaning base station 100 can be 0 degrees, and the corresponding liquid level can be 0. As the volume of cleaning liquid in the water tank assembly 1 increases, the floating component in the floating assembly 21 gradually rises under the action of the cleaning liquid, thereby driving the magnetic component 22 in the magnetic component part 212 to rotate through the connecting rod, causing the angle of the magnetic field inside the cleaning base station 100 to change. The magnetic component 22 cooperates with the second liquid level detection assembly 3, which can detect the analog signal of the angle change of the magnetic field inside the cleaning base station 100, and the second liquid level detection assembly 3 outputs a voltage value. The processing unit can read the voltage value and calculate the current magnet angle, i.e., the magnet movement range value, based on the correspondence between the voltage value and the magnet angle. In this way, the processing unit can further determine the installation posture of the magnetic component 22 based on the magnet movement range value, determine the magnet movement angle based on the installation posture and the magnet movement range value, and determine the real-time liquid level corresponding to the magnet movement angle based on the correlation between the angle and the liquid level.

[0061] Optionally, the cleaning base station 100 can communicate with a mobile device to transmit the detected real-time liquid level to the mobile device and display the real-time liquid level on the terminal interface of the mobile terminal, thereby improving the effectiveness of information display. Users can adjust the cleaning liquid in the water tank assembly 1 in a timely manner, further improving the cleaning efficiency of the cleaning equipment.

[0062] Optionally, after determining the current real-time liquid level, the cleaning base station 100 can automatically compare it with the liquid level required for the cleaning task to be performed. If the real-time liquid level is lower than the liquid level required for the cleaning task, it can automatically trigger a replenishment operation of the cleaning liquid, increasing the cleaning liquid in the water tank assembly 1 until the liquid level requirement of the cleaning task is met. Alternatively, the cleaning base station 100 can also generate a replenishment prompt message for the cleaning liquid, transmit the replenishment prompt message to the mobile device, and display the replenishment prompt message on the terminal interface of the mobile terminal, improving the effectiveness of the information display so that the cleaning liquid in the water tank assembly 1 can be replenished in a timely manner, further improving the cleaning efficiency of the cleaning equipment.

[0063] The cleaning base station 100 in this invention can be directly connected to a mobile terminal, or it can be connected to a mobile terminal through a server. This invention does not limit the conversion relationship between voltage value and magnet angle, but can limit the correlation between base angle and liquid level. Those skilled in the art can determine the detailed correlation between voltage value, magnet angle, and liquid level based on the specific capacity of the magnetic components and water tank components in the actual application scenario.

[0064] Based on this, the cleaning base station 100 can automatically calibrate the magnetic component 22 in both directions, confirm the foolproof signal, and realize real-time and accurate detection of the liquid level in the water tank component 1.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
