[0009] Optionally, the limiting portion comprises a baffle arranged above the connecting portion, the baffle being connected with the mounting frame and located between the two ends of the connecting portion, and wherein, based on the surface of the liquid in the water tank assembly reaching the specific position, the connecting portion abuts against the baffle.

[0010] Optionally, the float body comprises: a seat body connected with the connecting part and provided with an opening; and a cover body covering the opening and connected with the seat body, the cover body and the seat body forming a mounting cavity in which the non-contact inductive element is arranged.

[0011] Optionally, one of the seat body and the cover body is provided with a mounting portion, and the other is provided with a limiting structure matched with the mounting portion, the mounting portion being used for mounting the non-contact inductive element, and the limiting structure being used for limiting the non-contact inductive element mounted on the mounting portion.

[0012] Optionally, the mounting portion comprises a mounting groove arranged on the seat body, and the limiting structure comprises a first protruding structure arranged on the cover body, an end of the first protruding structure away from the cover body being adapted to be located in the mounting groove.

[0013] Optionally, the float body is in a solid structure or a hollow structure; and / or the seat body and the connecting part are in an integrated structure.

[0014] Optionally, at least one of the connecting part and the float body is provided with an anti-reverse mounting structure.

[0015] Optionally, the connecting part is provided with a liquid discharge hole penetrating the connecting part in the vertical direction.

[0016] Embodiments of the second aspect of the present application provide a cleaning system, comprising: a cleaning device comprising a cleaning part and / or a liquid storage tank; and the base station of any one of the first aspect, the cleaning device and the base station being communicatively connected, and the liquid contained in the water tank assembly being adapted to act on the cleaning part and / or the liquid storage tank.

[0017] According to embodiments of the present invention, a base station and a cleaning system are provided, wherein the base station includes a water tank assembly, a base station body, a float assembly, a non-contact sensing element, and a non-contact sensed element. The water tank assembly contains a float assembly, which includes a float body that floats on the surface of the liquid. One of the non-contact sensing element and the non-contact sensed element is disposed on the float body, and the other is disposed on the base station body. That is, one of the non-contact sensing element and the non-contact sensed element moves with the float body, while the other is fixed at a position on the base station body. Thus, as the float body floats up and down under the influence of the liquid, the non-contact sensing element detects different signal parameters emitted by the non-contact sensed element. Based on these different signal parameters, the location of the non-contact sensed element within the water tank assembly can be determined. The liquid level detection device can simultaneously detect both the liquid level inside the container and the current position of the container, compared to related technologies where liquid level detection devices can only detect the liquid level inside the water tank assembly and not the current position. This expands the functionality of the liquid level detection device. Furthermore, compared to related technologies that use two sets of detection devices to detect both the liquid level inside the water tank assembly and the current position of the water tank assembly, this simplifies the setup of one detection device, thus simplifying the product structure and the system software program and algorithm. This effectively saves costs and makes it suitable for widespread application. Attached Figure Description

[0051] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the technical solutions provided by the present application. However, it will be apparent to one of ordinary skill in the art that the technical solutions provided by the present application can be practiced without one or more of these specific details.

[0052] It should be noted that the terms used herein are only used to describe specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in the specification, it means that there is a presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or combinations thereof.

[0053] Now, the exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in various different forms, and should not be interpreted only as limiting the embodiments set forth herein. It should be understood that the embodiments are provided so that the disclosure of the present application is complete and complete, and the ideas of the exemplary embodiments are sufficiently conveyed to those of ordinary skill in the art.

[0054] Optional embodiments of the first aspect of the present application provide a base station, and optional embodiments of the second aspect of the present application provide a cleaning system.

[0055] The cleaning system includes a cleaning device and a base station. The cleaning device includes a sweeping robot, a mopping robot, a floor polishing robot, a sweeping and mopping integrated robot, or other devices that meet the requirements. It can be understood that the cleaning device can be a movable cleaning device, such as a self-moving cleaning device. The cleaning device and the base station are communicatively connected. The cleaning device includes a cleaning part, specifically, a wet cleaning part, which can perform wet cleaning on a surface to be cleaned. The base station includes a base station body and a water tank assembly 200, which is arranged on the base station body and is used to contain liquid, including clean water, cleaning liquid, disinfectant, etc. When the cleaning device completes wet cleaning or the cleaning part is dirty, the cleaning device moves to the base station, and the cleaning part is washed by the liquid in the water tank assembly 200. In addition, the water tank assembly 200 provided by the embodiment of the present application can also inject water into the liquid storage tank of the cleaning robot through the connecting device. In other embodiments of the present application, the base station can be configured with more than one water tank assembly 200. In addition to the above-mentioned water tank assembly 200 for containing clean water, cleaning liquid, disinfectant, etc., a water tank assembly 200 for collecting sewage after cleaning the cleaning part of the cleaning robot can also be configured.

[0056] It can be understood that the water tank assembly 200 provided by the embodiment of the present application can also be other containers that meet the requirements, and the liquid in the water tank assembly 200 can also act on other components to be cleaned. In order to facilitate description, the present embodiment takes a sweeping and mopping integrated robot as an example, and a base station communicatively connected with the sweeping and mopping integrated robot as an example to describe the technical solutions of the present disclosure.

[0057] In an optional embodiment of the present application, the cleaning device can include a device body, a sensing system, a control system, a driving system, a cleaning system, an energy system, and a human-computer interaction system, etc. The various systems cooperate with each other to enable the cleaning device to move autonomously to achieve cleaning functions. The functional elements constituting the above-mentioned systems in the cleaning device are integrally arranged in the device body. The cleaning part of the cleaning system includes a dry cleaning part and a wet cleaning part, thereby realizing sweeping and mopping functions.

[0058] In some possible implemented embodiments provided by the present application, as Figure 1 , Figure 2 and Figure 3As shown, the base station further comprises a float assembly 110, a non-contact induction element 130 and a non-contact inducted element 140, wherein the float assembly 110 is arranged inside the water tank assembly 200 and comprises a float body 111 capable of floating under the action of liquid, i.e. the float body 111 floats up and down with the rising or falling of the liquid surface, and the float body 111 is capable of floating on the liquid surface under the action of liquid. The non-contact induction element 130 is used for detecting the non-contact inducted element 140, such as detecting the signal parameters emitted by the non-contact inducted element 140, one of the non-contact induction element 130 and the non-contact inducted element 140 is arranged on the float body 111, and the other is arranged separately from the water tank assembly and on the base station body, i.e. one of the non-contact induction element 130 and the non-contact inducted element 140 moves with the float body 111, and the other is arranged at a fixed position outside the water tank assembly 200, such as arranged on the base station body at the installation position of the water tank assembly 200. In this way, during the up and down floating of the float body 111 under the action of liquid, the signal parameters emitted by the non-contact inducted element 140 detected by the non-contact induction element 130 are different, and then the liquid level range in the water tank assembly 200 can be determined according to the different signal parameters, and the current position of the water tank assembly 200 can be determined. For example, when the water tank assembly 200 is arranged on the base station body and the liquid surface in the water tank assembly 200 is at a specific position, the non-contact induction element 130 can sense the signal parameters emitted by the non-contact inducted element 140, indicating that the water tank assembly 200 is correctly installed on the base station body, and the liquid surface in the water tank assembly 200 reaches a specific position, i.e. a set of detection devices including the float assembly 110, the non-contact induction element 130 and the non-contact inducted element 140 can simultaneously detect the liquid level in the water tank assembly 200 and the current position of the water tank assembly 200. Compared with the liquid level detection device in the related art which can only detect the liquid level in the water tank assembly 200 and cannot detect the current position of the water tank assembly 200, the function of the float assembly 110 is expanded, and compared with the related art which uses two sets of detection devices to realize the liquid level detection in the water tank assembly 200 and the current position detection of the water tank assembly 200, the setting of one set of detection devices is simplified, i.e. the structure of the product is simplified, and the system software program and algorithm are simplified, which can effectively save costs and is suitable for popularization and application.

[0059] Further, in one aspect, the non-contact inductive element 140 is arranged on the float body 111, and the non-contact inductive element 130 is arranged on the base body; in another aspect, the non-contact inductive element 130 is arranged on the float body 111, and the non-contact inductive element 140 is arranged on the base body. The different arrangement positions of the non-contact inductive element 140 and the non-contact inductive element 130 can meet the requirements of different structures and different performances of the non-contact inductive element 140 and the non-contact inductive element 130, and expand the use range of the product. It can be understood that the non-contact inductive element 140 can include a magnetic element, a light emitting element or other components meeting the requirements, and the non-contact inductive element 130 can include a magnetic inductive element, a light inductive element or other components meeting the requirements. The non-contact inductive element 140 or the non-contact inductive element 130 arranged on the float body 111 can be located inside or outside the float body 111 or other positions meeting the requirements, which is not limited in the present application.

[0060] Further, the water tank assembly 200 can be a clean water tank for containing cleaning liquid, or a dirty water tank for containing dirty liquid. Due to the different functions of the water tank assembly, the arrangement positions of the float body 111, the non-contact inductive element 130 and the non-contact inductive element 140 are also different. For example, the liquid in the clean water tank is mainly used for cleaning the cleaning part or supplying liquid to the liquid storage tank, that is, the liquid in the clean water tank will become less and less during the working process, therefore, it is necessary to ensure that a certain amount of liquid in the clean water tank can act on the cleaning part and / or the liquid storage tank, that is, it is necessary to detect when the clean water tank is out of liquid. Therefore, the float body 111 can be arranged on the bottom wall or the side wall of the clean water tank, and one of the non-contact inductive element 130 and the non-contact inductive element 140 is arranged on the base body and close to the position of the bottom wall of the water tank. In this way, when the clean water tank assembly 200 is installed on the base body, and the liquid level in the clean water tank reaches a certain position, the non-contact inductive element 130 can induct the non-contact inductive element 140, which indicates that the clean water tank assembly 200 is correctly installed on the base body, and the liquid in the water tank assembly is less and needs to be replenished in time.

[0061] For example, the sewage tank is mainly used for collecting the liquid in the cleaning process, that is, the liquid in the sewage tank will be more and more during the working process of the cleaning equipment. In order to avoid the liquid in the sewage tank overflowing and affecting the reliability or cleaning effect of the cleaning equipment, it is necessary to detect when the sewage tank is full of liquid. Therefore, the float body 111 can be arranged on the top wall or side wall of the clean water tank, one of the non-contact sensing element 130 and the non-contact sensed element 140 is arranged on the base station body and close to the position of the top wall of the water tank. In this way, when the clean water tank assembly 200 is installed on the base station body, and the liquid level in the clean water tank reaches a certain position, the non-contact sensing element 130 can sense the non-contact sensed element 140, which indicates that the clean water tank assembly 200 is correctly installed on the base station body, and the liquid in the water tank assembly 200 is full, and the liquid in the sewage tank needs to be poured out in time.

[0062] In some possible implementation embodiments provided by the present application, the non-contact sensed element 140 includes a magnetic element, and the non-contact sensing element 130 includes a Hall sensor, such as a magnetic sensing element. The magnetic element is arranged on the float body 111, and the Hall sensor is arranged on the base station body. Specifically, the magnetic element can be arranged inside the float body 111. Such arrangement can avoid the problem that the magnetic element arranged outside the float body 111 is wetted by the liquid, corroded, caused failure, and interfered with signal transmission strength, thereby facilitating to improve the service life of the magnetic element and the stability and reliability of the transmitted signal.

[0063] That is, the base station provided by the embodiment of the present application is that the float assembly 110 is arranged inside the water tank assembly 200, the magnetic element is arranged inside the float body 111 arranged inside the water tank assembly 200, and the Hall sensor is arranged on the base station body. Under the action of the liquid, when the magnetic element floats to the detection range of the Hall sensor, it indicates that the liquid level in the water tank assembly 200 reaches a certain height, and the water tank assembly 200 is correctly installed on the base station body. The specified height can be 10 mm, 20 mm, 30 mm, 50 mm or other values or ranges meeting the requirements, and the correct installation of the water tank assembly 200 on the base station body can be reliable and accurate connection between the water tank assembly 200 and the base station body.

[0064] It can be understood that the base station provided by the embodiment of the present application sets the float assembly 110 in the inside of the water tank assembly 200, sets the magnetic member in the inside of the float body 111, and sets the Hall sensor on the base station body. Since the position of the magnetic member is fixed during the floating process of the float body 111, the Hall sensor can detect the signals of different parameters emitted by the magnetic member. Therefore, by reasonably setting the detection range of the Hall sensor, for example, the detection range can be a preset threshold of the signal emitted by the magnetic member received by the Hall sensor, when the signal parameter emitted by the magnetic member received by the Hall sensor reaches the preset threshold, the liquid level in the water tank assembly 200 reaches the specified height, and the water tank assembly 200 is correctly installed on the base station body, that is, the magnetic member can float with the float body 111 into the detection range of the Hall sensor. Therefore, by reasonably setting the positions of the magnetic member and the Hall sensor, the detection range of the Hall sensor, and cooperating with the float assembly 110, the liquid level in the water tank assembly 200 and whether the water tank assembly 200 is in place can be detected, which is simple in structure, easy to implement, low in cost, and suitable for popularization and application. The detection range of the magnetic induction member is indicated by P in Figure 2 and Figure 3 .

[0065] Specifically, the magnetic member can be a magnetic strip, a magnetic ring or other magnetic structure meeting the requirements, and the Hall sensor can be a magnetic induction sensor or other structure meeting the requirements. Specifically, the magnetic induction sensor can be a ring structure or a sheet structure or other structure meeting the requirements.

[0066] Further, the number of Hall sensors can be one, two or more. Two or more Hall sensors are arranged at different positions of the base station body, which can sense that the liquid surface at different heights in the water tank assembly 200 reaches different specific positions, that is, the liquid surface at different heights in the water tank assembly 200 can be detected, which expands the use range of the product.

[0067] In some possible implementation embodiments provided by the present application, the base station further comprises a controller, and the non-contact sensing element 130 is electrically connected to the controller of the base station to output the sensing result to the controller. It can be understood that the controller of the base station can also interact with information of the cleaning robot or a remote control terminal (APP) and the like. In this way, the controller can conveniently control other components of the cleaning system according to the sensing result of the non-contact sensing element 130, such as adjusting the position of the water tank assembly 200 to correctly install the water tank assembly 200 on the base station body according to the sensing result, supplementing the water tank assembly 200 in a timely manner according to the sensing result to ensure that the liquid in the water tank assembly 200 can reliably and sufficiently act on the cleaning part and / or the liquid storage tank, and controlling the cleaning equipment to stop working according to the sensing result to avoid the sewage in the water tank assembly 200 from overflowing, thereby greatly improving the reliability of the working of the cleaning system.

[0068] In some embodiments described above, as shown in Figure 6 、 Figure 7 and Figure 8 , the float assembly 110 further comprises a mounting frame 112 and a connecting part 113, the mounting frame 112 is arranged in the interior of the water tank assembly 200 and detachably connected with the water tank assembly 200, one end of the connecting part 113 is rotatably connected with the mounting frame 112, and the other end is connected with the float body 111, that is, the float body 111 is capable of swinging in the substantially up-down direction relative to the mounting frame 112 under the action of the liquid, that is, the connecting part 113 is capable of swinging relative to the mounting frame 112 in the direction close to the bottom wall of the water tank assembly 200 and in the direction away from the bottom wall of the water tank assembly 200, thereby driving the magnetic part to swing up and down relative to the bottom wall of the water tank assembly 200.

[0069] Since the mounting frame 112 is detachably connected with the water tank assembly 200, that is, the float assembly 110 can be assembled into different water tank assemblies 200 through the mounting frame 112, and the non-contact sensing element is detachably arranged on the base station body, so that the non-contact sensing element 130 can detect the liquid level and the current position in different water tank assemblies 200, that is, the float assembly, the non-contact sensing element 130 and the non-contact sensing element 140 can be regarded as a liquid level detection device as a whole and can be configured as a standardized module in corresponding products or scenes, thereby expanding the use range of the liquid level detection device. Meanwhile, the arrangement of the mounting frame 112 facilitates the user to detach the float assembly 110 from the water tank assembly 200 for maintenance and cleaning, thereby greatly improving the user experience.

[0070] Specifically, the mounting frame 112 is provided with a through hole, the connecting part 113 is provided with a mounting hole, the connecting part 113 and the mounting frame 112 are rotationally connected by the connecting piece 150 penetrating the mounting hole and the through hole. Specifically, the connecting piece 150 is a rotating shaft, a hinge pin, or other connecting piece 150 meeting the requirements, and the axis of rotation of the connecting part 113 relative to the mounting frame 112 is parallel to the plane in which the bottom wall of the water tank assembly 200 lies, such as the axis of the rotating shaft being parallel to the plane in which the bottom wall of the water tank assembly 200 lies. In this way, the connecting part 113 can only swing in the vertical direction relative to the mounting frame 112.

[0071] Since the float body 111 floats under the action of the liquid and drives the connecting part 113 to rotate relative to the mounting frame 112, while driving the magnetic part to swing in the vertical direction relative to the bottom wall of the water tank assembly 200, by providing a limiting part 114 on at least one of the mounting frame 112 and the connecting part 113, the limiting part 114 is used to limit the rotation range of the connecting part 113 relative to the mounting frame 112, thereby limiting the swing of the magnetic part in the up-down direction relative to the bottom wall of the water tank assembly 200. When the liquid level in the water tank assembly 200 reaches a specified height, and when the water tank assembly 200 is installed on the base body, the magnetic part can accurately and reliably float into the detection range of the Hall sensor under the driving of the float body 111. That is, the limiting part 114 is provided so that when the liquid level in the water tank assembly 200 reaches a predetermined height and the water tank assembly 200 is installed on the base body, the magnetic part can float into the detection range of the Hall sensor, so that a set of Hall sensors and magnetic parts cooperate with the float assembly to detect the liquid level in the water tank assembly 200 and whether the water tank assembly 200 is in place, and ensure the accuracy and reliability of the detection results. The structure is simple, the cost is low, and it is suitable for popularization and application.

[0072] It can be understood that the limiting part 114 can be provided on one of the mounting frame 112 or the connecting part 113, or can be provided on both the mounting frame 112 and the connecting part 113. Different positions of the limiting part 114 can meet the requirements of different structures of the limiting part 114.

[0073] Further, the limiting part 114 comprises a baffle plate arranged on the mounting rack 112, the baffle plate is located above the connecting part 113 and between the two ends of the connecting part 113, that is, the baffle plate is located between the end where the connecting part 113 is connected with the mounting rack 112 and the end where the connecting part 113 is connected with the float body 111, such arrangement makes the connecting part 113 capable of abutting against the baffle plate during the process that the float body 111 is floated upward under the action of the liquid and drives the connecting part 113 to swing relative to the mounting rack 112 in the direction away from the bottom wall of the water tank assembly 200, that is, the float body 111 will not float upward with the increase of the liquid level after abutting against the baffle plate, but will only sink with the decrease of the liquid level. Since the magnetic member is arranged inside the float body 111, the position of the magnetic member relative to the float body 111 is fixed during the floating process of the float body 111, therefore, the position of the magnetic member relative to the water tank assembly 200 is fixed when the connecting part 113 abuts against the baffle plate, so the height of the liquid surface when the connecting part 113 abuts against the baffle plate is defined as the specified height, in this state, the detection range of the Hall sensor is reasonably limited, so that after the water tank assembly 200 is correctly installed to the structure to be installed, the magnetic member is located in the detection range of the Hall sensor, and then through the Hall sensor, the liquid level in the water tank assembly 200 can be detected, and whether the water tank assembly 200 is correctly installed to the structure to be installed can also be detected, which is simple in structure and low in manufacturing cost.

[0074] For example, the water tank assembly 200 in the embodiment of the present application is a clean water tank, the water tank assembly 200 is applied to a base station of a cleaning system, and the water tank assembly 200 is detachably installed on a base station body, wherein the Hall sensor is arranged on the base station body, the mounting rack 112 of the float assembly 110 is fixed to the bottom wall of the water tank assembly 200, one end of the connecting part 113 is rotationally connected with the mounting rack 112 through a rotating shaft, the other end of the mounting rack 112 is connected with the float body 111, and the magnetic member is arranged in the float body 111, the float body 111 is a low-density material member, and when the float body 111 is immersed in the liquid and subjected to the buoyancy, the float body 111 will rotate around the rotating shaft and drive the magnetic member to swing relative to the mounting rack 112, the position of the float body 111 changes, thereby causing the change of the surrounding magnetic field intensity, and the Hall sensor receives the change information to determine the change of the liquid level in the water tank assembly 200 and / or the current position of the water tank assembly 200. By arranging the limiting part 114 on the mounting rack 112, the limiting part 114 limits the rotation of the connecting part 113, and when the liquid level in the water tank assembly 200 reaches the specified height, the connecting part 113 abuts against the limiting part 114. Therefore, as Figure 2 and Figure 4As shown, if the magnetic piece floats into the detection range of the Hall sensor, i.e. the Hall sensor detects that the magnetic piece floats into the detection range P, it indicates that the liquid level in the water tank assembly 200 reaches the preset height, and the water tank assembly 200 is installed in place. It can be understood that the Hall sensor can send a corresponding signal to the cleaning system through the electrical connection between the controller of the base station and the Hall sensor, which tells the cleaning device, and / or the base station body, and / or the water tank assembly 200 that there is liquid in the water tank assembly 200, the liquid reaches the specified liquid level, and the water tank assembly 200 is accurately installed on the base station body.

[0075] When there is no liquid or less liquid in the water tank assembly 200, and the liquid level does not reach the specified height, the connecting portion 113 and the limiting portion 114 will not abut, and the float body 111 will sink or will not reach the specified position. At this time, the magnetic piece will not float into the detection range of the Hall sensor, as shown in Figure 3 and Figure 5 , i.e. the Hall sensor will not detect that the magnetic piece floats into the detection range, which indicates that the liquid level in the water tank assembly 200 does not reach the specified height at this time, and / or the water tank assembly 200 is not installed in place. It can be understood that since the Hall sensor is electrically connected with the controller, the Hall sensor can send a corresponding signal to the cleaning system at this time, which tells the cleaning device, and / or the base station body, and / or the water tank assembly 200 that the water tank assembly 200 is short of liquid and / or the water tank assembly 200 is not installed in place, reminding the user to replenish the liquid in time and check whether the connection between the water tank assembly 200 and the base station body is reliable and accurate.

[0076] In some possible implemented embodiments provided by the present application, as shown in Figure 6 , Figure 7 and Figure 8 , the float body 111 comprises a seat body 115 and a cover body 116, the seat body 115 is connected with the connecting portion 113 and is provided with an opening, the cover body 116 is covered on the opening and is connected with the seat body 115, an installation cavity is formed between the cover body 116 and the seat body 115, and the non-contact inductive element 140 is arranged in the installation cavity. In this way, the seat body 115 and the cover body 116 can well protect the non-contact inductive element 140, so as to avoid that the liquid in the water tank assembly 200 wets and corrodes the non-contact inductive element 140 or causes a fault, thereby being conducive to prolonging the service life of the non-contact inductive element 140 and improving the reliability of the float assembly 110. The seat body 115 and the connecting portion 113 can be an integral structure, which is conducive to improving the reliability of the connection between the float body 111 and the connecting portion 113, and is conducive to batch production, reducing manufacturing cost and installation cost.

[0077] Further, one of the seat body 115 and the cover body 116 is provided with a mounting portion 117, and the other is provided with a limiting structure matched with the mounting portion 117. The non-contact inductive element 140 is mounted on one of the seat body 115 and the cover body 116 through the mounting portion 117, and the non-contact inductive element 140 mounted on the mounting portion 117 is limited by the limiting structure, so as to ensure that the non-contact inductive element 140 can be reliably and stably mounted on the float body 111. That is, the non-contact inductive element 140 on the float body 111 is stationary relative to the float body 111 during the floating process of the float body 111 under the action of the liquid, so as to ensure the accuracy of the liquid level detection device in detecting the liquid level and the current position of the water tank assembly 200.

[0078] In the mounting portion 117 is arranged on the seat body 115, and the limiting structure is arranged on the cover body 116, or the mounting portion 117 is arranged on the cover body 116, and the limiting structure is arranged on the seat body 115. Different arrangement positions of the mounting portion 117 and the limiting structure can meet the demand of different structures of the mounting portion 117 and the limiting structure, and expand the use range of the product.

[0079] Specifically, as shown in Figure 7 and Figure 8 , the mounting portion 117 includes a mounting groove arranged on the seat body 115, and the limiting structure includes a first protruding structure 118 arranged on the cover body 116. An end of the first protruding structure 118 away from the cover body 116 is adapted to be located in the mounting groove. When the non-contact inductive element 140 is mounted in the mounting groove, the first protruding structure 118 is located in the mounting groove and abuts against the non-contact inductive element 140 during the process of connecting the cover body 116 and the seat body 115. The non-contact inductive element 140 can be reliably and firmly fixed between the mounting groove and the first protruding structure 118, so that the non-contact inductive element 140 is stationary relative to the float body 111 during the floating process of the float body 111.

[0080] In some possible implementation embodiments of the present application, the float body 111 can be a solid structure or a hollow structure. Different structures of the float body 111 can meet the demand of different structures of the float assembly 110, and expand the use range of the product.

[0081] Specifically, when the float body 111 is a solid structure, if the float assembly 110 is not provided with one of the non-contact sensing element 130 and the non-contact sensed element 140, the seat body 115 and the cover body 116 can be an integrated structure and are provided as a solid structure, or the seat body 115 and the cover body 116 are a split structure, and after the cover body 116 covers the seat body 115, there is no gap between the two, forming a solid structure; when the float body 111 is a solid structure, and the float assembly 110 is provided with one of the non-contact sensing element 130 and the non-contact sensed element 140, the space of the mounting cavity matches the outer dimensions of the non-contact sensing element 130 or the non-contact sensed element 140, that is, the non-contact sensing element 130 or the non-contact sensed element 140 is installed in the mounting cavity, and after the cover body 116 covers the seat body 115, there is no gap between the cover body 116, the seat body 115, the non-contact sensing element 130 or the non-contact sensed element 140, and the cover body 116 and the seat body 115, and the float body 111 is a solid structure.

[0082] When the float body 111 is a hollow structure, the space of the mounting cavity is greater than the outer dimensions of the non-contact sensing element 130 or the non-contact sensed element 140, so that after the non-contact sensing element 130 or the non-contact sensed element 140 is installed in the mounting cavity and the cover body 116 covers the seat body 115, there is a gap between the non-contact sensing element 130 or the non-contact sensed element 140 and the cover body 116 and the seat body 115, and the float body 111 is a hollow structure. It can be understood that the non-contact sensing element 130 or the non-contact sensed element 140 can also not be arranged in the mounting cavity, that is, the float body 111 is a hollow structure and the float assembly 110 is not provided with the non-contact sensing element 130 or the non-contact sensed element 140.

[0083] In some possible implementation embodiments provided by the present application, as shown in Figure 7 The anti-reverse installation structure 120 is arranged on at least one of the connecting portion 113 and the float body 111, and the arrangement of the anti-reverse installation structure 120 can avoid reverse installation of the float composed of the connecting portion 113 and the float body 111 relative to the mounting frame 112, for example, the anti-reverse installation structure 120 can avoid reverse installation of the float composed of the connecting portion 113 and the float body 111 relative to the bottom wall of the water tank assembly 200, and further can avoid change of the position of the non-contact sensing element 130 or the non-contact sensed element 140 installed on the float body 111 relative to the bottom wall of the water tank assembly 200, thereby affecting the accuracy of detection of the liquid level in the water tank assembly 200 and the in-place of the water tank assembly 200.

[0084] The anti-reverse structure 120 can be arranged on the float body 111, can be arranged on the connecting portion 113, or can be arranged on both the float body 111 and the connecting portion 113. The anti-reverse structure 120 arranged at different positions can meet the requirements of different structures of the connecting portion 113 and the float body 111. For example, when the seat body 115 of the float body 111 and the connecting portion 113 are integrated, the anti-reverse structure 120 arranged on the connecting portion 113 can prevent the float body 111 from being reversely arranged relative to the water tank assembly 200. It can be understood that the anti-reverse structure 120 can also be directly arranged on the float body 111 to prevent the float body 111 from being reversely arranged relative to the water tank assembly 200. The anti-reverse structure 120 can also be arranged on both the float body 111 and the connecting portion 113 to prevent the float body 111 from being reversely arranged relative to the water tank assembly 200.

[0085] Further, the seat body 115 and the connecting portion 113 are integrated, the anti-reverse structure 120 includes a second protruding structure arranged at the bottom of the connecting portion 113. The second protruding structure can prevent the float body 111 from being reversely arranged relative to the bottom wall of the water tank assembly 200. The second protruding structure is convenient to process, easy to implement, does not cause water accumulation, has a good reminding effect, and is suitable for popularization and application. It can be understood that the anti-reverse structure 120 can also be other structures meeting the requirements, which are not limited in the present application.

[0086] In some possible implementation examples provided by the present application, as shown in Figure 7 The connecting portion 113 is provided with a liquid discharge hole 119. The liquid discharge hole 119 penetrates the connecting portion 113 in the vertical direction, that is, the liquid discharge hole 119 penetrates the top and bottom of the connecting portion 113. In this way, water can continuously flow through the liquid discharge hole 121 during the up-and-down floating of the float body 111, and impurities in the water are not easy to adhere to the float assembly, thereby reducing the breeding of bacteria and the generation of odor.

[0087] It can be understood that the number of the liquid discharge hole 119 can be one, two or more. The liquid discharge hole 119 can be a circular hole, a square hole or other shapes meeting the requirements, which are not limited in the present application.

[0088] Further, the top of the float body 111 of the float assembly 110 is curved, for example, the float body 111 is a cylindrical structure, or a spherical structure, or other structure meeting the requirements, for example, the side wall of the cylindrical structure is the top of the float body 111, for example, any one face of the spherical structure is the top of the float body 111, which is arranged in this way so that the float body encounters smaller water resistance during floating, thereby facilitating to improve the detection sensitivity, at the same time, the curved surface can guide the liquid, thereby avoiding the situation that the top of the float body 111 is filled with water, which is beneficial to further improve the quality of the liquid in the tank body.

[0089] Wherein, the float body 111 and the connecting part 113 jointly form a float, the float is a low-density material piece, that is, the float body 111 and the connecting part 113 are both low-density material pieces, so as to ensure that the float body 111 and the connecting part 113 can float on the surface of the liquid under the action of the liquid. It can be understood that the materials of the float body 111 and the connecting part 113 can be the same or different, and the present application does not make specific limitation.

[0090] In some possible implementation embodiments provided by the present application, as shown in Figure 9 , Figure 10 and Figure 11 , the water tank assembly 200 includes a lower shell 210, an upper shell 220 and a handle 230, wherein the top end of the lower shell 210 is provided with an opening, the lower shell 210 includes a first mounting structure 211, the upper shell 220 is pivotally connected with the first mounting structure 211 and can open and close the opening. That is to say, the water tank assembly 200 provided by the present application is a combined water tank, the water tank is combined by the upper shell 220 and the lower shell 210, when the upper shell 220 closes the opening of the lower shell 210, the liquid can be contained in the closed space formed by the upper shell 220 and the lower shell 210, so as to ensure that the liquid therein is not spilled. When the upper shell 220 opens the opening of the lower shell 210, the liquid in the lower shell 210 can be poured out by overturning or tilting the lower shell 210.

[0091] Wherein, the upper shell and the lower shell form a closed space containing liquid, the float assembly 110 is arranged in the closed space, and the position of the float assembly 110 can be reasonably arranged according to whether the water tank assembly is a clean water tank or a sewage tank. Specifically, the float assembly 110 is arranged in the interior of the lower shell 210, and the float assembly is fixed in the interior of the lower shell 210 through the mounting frame 112, such as being fixed to the bottom wall or the side wall of the lower shell 210. One end of the connecting part 113 is rotationally connected with the mounting frame 112, and the other end is connected with the float body 111, so that the float body 111 can float on the surface of the liquid under the action of the liquid. The non-contact inductive element 140 is arranged on the float body 111, and the non-contact inductive element 130 is arranged on the base station body, so that when the float body 111 floats under the action of the liquid and drives the non-contact inductive element 140 to float, the signal range or the presence or absence of signal sensed by the non-contact inductive element 130 can be used to judge the liquid level condition in the lower shell 210, and whether the lower shell 210 is installed in place can be judged. It can be understood that the float assembly 110 can also be arranged on the side wall of the lower shell 210, or arranged on the side wall of the upper shell 220 or the top wall of the upper shell 220, and the present application does not make specific limitation.

[0092] Further, the handle 230 includes a holding part 232 and a transition part 231 located at both ends of the holding part 232, and the transition part 231 is rotationally connected with the lower shell 210, thereby being able to drive the holding part 232 to rotate relative to the lower shell 210. A user can hold the water tank assembly 200 through the holding part 232 to carry the water tank assembly 200, which is simple and convenient to operate. Since the handle 230 provided by the embodiment of the present application is rotationally connected with the lower shell 210, and is not rotationally connected with the upper shell 220, such arrangement can effectively prevent the problem that the lower shell 210 and the upper shell 220 are separated and the lower shell 210 is inclined to cause liquid to spill when the user lifts the water tank assembly 200 through the holding part 232 due to unreliable connection or non-locking of the lower shell 210 and the upper shell 210. The handle 230 is connected with the lower shell 210, which is conducive to improving the reliability of carrying the water tank assembly 200 and avoiding waste of liquid resources.

[0093] In the embodiment, the limiting device 213 can also be arranged on the outer sidewall of the lower shell 210, and the limiting device 213 limits the range of the transition portion 231 relative to the lower shell 210 to rotate towards the first mounting structure 211, that is, the limiting device 213 can limit the amplitude of the transition portion 231 to rotate towards the first mounting structure 211. Such arrangement can avoid that the handheld portion is located on the periphery of the lower shell 210 during the process of the transition portion 231 rotating towards the first mounting structure 211 with a large amplitude, for example, the handheld portion is located on the periphery of the lower shell 210 below the first mounting structure 211. Thus, after the opening of the upper shell 220 is opened, the upper shell 220 blocks the handheld portion on the periphery of the lower shell 210, which is not conducive to moving the handheld portion above the lower shell 210, and further hinders the user from picking up the water tank assembly 200 through the handheld portion to pour liquid, supplement liquid, carry the water tank assembly 200 and the like. That is, the embodiment of the present application limits the amplitude of the transition portion 231 to rotate towards the first mounting structure 211 through the limiting device 213, so that the maximum amplitude of the holding portion 232 to rotate towards the first mounting structure 211 is that the holding portion 232 is located above the lower shell 210. Thus, when the opening of the upper shell 220 is opened, the upper shell 220 rotates to the rear wall of the lower shell 210, and the holding portion 232 is located above the lower shell 210, which is convenient for the user to pick up the water tank assembly 200 through the holding portion 232 to pour liquid, supplement liquid, carry the water tank assembly 200 and the like, and the operation is simple and convenient to use.

[0094] In some possible implementation embodiments provided by the present application, as Figure 10As shown, the lower shell 210 is provided with a second mounting structure 212 connected with the transition portion 231, that is, the transition portion 231 of the handle 230 is rotationally connected with the second mounting structure 212, so as to realize the rotation of the handle 230 relative to the lower shell 210. The limiting structure 215 includes a limiting inclined surface located between the second mounting structure 212 and the first mounting structure 211. In this way, in the process of the transition portion 231 rotating towards the first mounting structure 211, the transition portion 231 will abut against the limiting inclined surface so as to make the holding portion 232 located above the lower shell 210, that is, the situation that the holding portion 232 rotates to the side of the lower shell 210 close to the first mounting structure 211 is avoided. It can be understood that, in the free state, the handle 230 will appear the following two situations due to the influence of gravity. The first situation: the transition portion 231 abuts against the limiting device 213. The second situation: the holding portion 232 abuts against the side wall of the lower shell 210 away from the first mounting structure 211. Among them, the first situation is convenient for the user to directly lift the water tank assembly 200 through the holding portion 232, and the second situation is small in occupied space and convenient for storage. When the user needs to rotate the upper shell 220 to open the opening of the lower shell 210, if the handle 230 is in the second situation, the user can directly rotate the upper shell 220 to open the opening of the lower shell 210, and if the handle 230 is in the first situation, the user needs to rotate the handle 230 to the second situation and then rotate the upper shell 220 to open the opening of the lower shell 210. In this way, even if the upper shell 220 opens the opening of the lower shell 210, the user can quickly, smoothly and conveniently lift the water tank assembly 200 through the holding portion 232, which is convenient to operate and greatly improves the operation experience of the user. The limiting inclined surface structure is simple and convenient to process, which is conducive to reducing the manufacturing cost of the water tank assembly 200 and is suitable for popularization and application.

[0095] By inclining the limiting inclined surface downward from the first mounting structure 211 to the second mounting structure 212, the holding portion 232 can be reliably and stably located above the lower shell 210 after the transition portion 231 abuts against the limiting inclined surface, which avoids the situation that the holding portion 232 rotates to the side of the lower shell 210 and the problem that the user is hindered from lifting the water tank assembly 200 through the holding portion 232 after the upper shell 220 opens the opening of the lower shell 210, so that the user can conveniently and quickly lift the water tank assembly 200 through the holding portion 232 located above the lower shell 210. It can be understood that, by reasonably setting the inclination angle of the limiting inclined surface, the specific position of the holding portion 232 above the lower shell 210 after the transition portion 231 abuts against the limiting inclined surface can be adjusted, so that the user's hand can quickly, accurately and conveniently hold the holding portion and lift the water tank assembly 200 through the holding portion 232.

[0096] Further, the number of the transition portions 231 can be two, and the two transition portions 231 are respectively located at two ends of the holding portion 232 and are respectively rotationally connected with two second mounting structures 212 on two sides of the lower shell 210, so that the holding portion 232 can rotate relative to the lower shell 210. The number of the limiting devices 213 can be one or two. If the number of the limiting devices 213 is one, one limiting device 213 can be located between any one of the second mounting structures 212 and the first mounting structure 211. If the number of the limiting devices 213 is two, each limiting device 213 is located between one of the second mounting structures 212 and the first mounting structure 211.

[0097] In the above embodiment, as shown in Figure 10 The top end of the lower shell 210 is provided with a boss structure 214 protruding outward, the first mounting structure 211 and the second mounting structure 212 are arranged on the boss structure 214, which avoids affecting the strength of the side wall of the lower shell 210 by directly arranging the first mounting structure 211 and / or the second mounting structure 212 on the outer side wall of the lower shell 210. The arrangement of the boss structure 214 is beneficial to improve the overall strength of the lower shell 210 and improve the reliability of the connection between the lower shell 210 and the upper shell 220 and the connection between the handle 230 and the lower shell 210. The limiting device 213 includes a protruding structure arranged on the boss structure 214, and the side of the protruding structure close to the upper shell 220 is provided with a limiting inclined surface. The protruding structure is convenient to process and manufacture and easy to implement. The arrangement of the protruding structure on the boss structure 214 reduces the influence of the limiting device 213 on the strength of the side wall of the lower shell 210, which is beneficial to further improve the reliability of the lower shell 210.

[0098] In some possible implementation examples of the present application, the second mounting structure 212 includes a mounting hole, the transition portion 231 includes a transition portion, a rotating portion and a protruding portion connected in sequence, the end of the transition portion away from the rotating portion is connected with the holding portion 232, the rotating portion is arranged in the mounting hole and can rotate in the mounting hole, that is, the rotating portion can rotate relative to the lower shell 210, and then the holding portion 232 is driven to rotate relative to the lower shell 210 through the rotating portion and the transition portion. Since the protruding portion is arranged on the side of the mounting hole away from the transition portion, the limitation of the protruding portion does not make the rotating portion separate from the mounting hole in the process of driving the protruding portion to rotate synchronously by the rotating portion, that is, the arrangement of the protruding portion and the rotating portion makes the handle 230 able to rotate relative to the lower shell 210 and not separate from the mounting hole of the lower shell 210, that is, the handle 230 is locked on the lower shell 210, which improves the reliability of the connection between the handle 230 and the lower shell 210.

[0099] Further, the rotating portion and the mounting hole have a gap, so that the rotating portion can rotate and slide in the mounting hole. Such arrangement improves the flexibility of the rotation of the handle 230 relative to the lower shell 210.

[0100] In some possible implementation of the present application, as shown in Figure 11 The water tank assembly 200 further comprises a handgrip 240 arranged on the outer bottom wall of the lower shell 210 and / or the outer side wall of the lower shell 210. The handgrip 240 is arranged such that the user can hold the handgrip 240 or hold the handgrip 240 and the handle 232 to carry or operate the water tank assembly 200. For example, when the upper shell 220 is opened to expose the opening of the lower shell 210, the user can hold the handgrip 240 and the handle 232 to pour the liquid in the lower shell 210. The operation is simple and convenient to use. In one aspect, the handgrip 240 is arranged on the outer bottom wall of the lower shell 210. In another aspect, the handgrip 240 is arranged on the outer side wall of the lower shell 210. In still another aspect, the handgrip 240 comprises two handgrips arranged on the outer bottom wall and the outer side wall of the lower shell 210, respectively. The different arrangement positions and different numbers of the handgrip 240 can meet the requirements of different structures of the handgrip 240 and different users, thereby expanding the use range of the product.

[0101] Further, since the upper shell 220 and the lower shell 210 are pivotally connected by the first mounting structure 211, the opening space is large when the upper shell 220 is opened to expose the opening of the lower shell 210. Therefore, when the handgrip 240 is arranged on the outer bottom wall of the lower shell 210, the handgrip 240 is arranged close to the first mounting structure 211. When the handgrip 240 is arranged on the outer side wall of the lower shell 210, the handgrip 240 is arranged below the first mounting structure 211. In this way, when the user holds the handgrip 240 to tilt the lower shell 210, the liquid in the lower shell 210 can quickly flow out through the part of the opening away from the first mounting structure 211, that is, the liquid flows out through the part of the opening with a large opening space, which is beneficial to improve the pouring efficiency of the liquid and improve the user's satisfaction.

[0102] Further, the handgrip 240 can be in an integrated structure or a split structure with the lower shell 210. The different arrangement modes of the handgrip 240 and the lower shell 210 can meet the requirements of different structures of the handgrip 240. For example, in one aspect, the handgrip 240 comprises a groove structure formed in the lower shell 210, such as a groove structure formed in the outer bottom wall of the lower shell 210 and / or a groove structure formed in the outer side wall of the lower shell 210. The groove structure is convenient to process and has a low cost. In another aspect, the handgrip 240 comprises a handgrip insert connected with the lower shell 210, such as the handgrip insert connected with the outer bottom wall of the lower shell 210 and / or the outer side wall of the lower shell 210 by means of embedding connection, plug-in connection, clamping connection, etc. Specifically, the handgrip insert can be in a plate structure, a rod structure or other structures meeting the requirements.

[0103] In some possible implementation of the present application, as shown inFigure 10 As shown, the water tank assembly 200 also includes a first seal 250, which is disposed on at least one of the upper shell 220 and the lower shell 210. When the upper shell 220 closes the opening of the lower shell 210, the first seal 250 seals the gap between the lower shell 210 and the upper shell 220, thereby ensuring that the closed space formed by the upper shell 220 and the lower shell 210 has good sealing performance, so that the liquid in the closed space will not overflow or leak from the gap between the upper shell 220 and the lower shell 210, thus ensuring the sealing performance of the water tank assembly 200.

[0104] Furthermore, the first sealing element 250 can be an elastic element. The elastic first sealing element 250 is beneficial to improving the sealing performance of the connection between the upper shell 220 and the lower shell 210. Specifically, the first sealing element 250 can be a sealing ring, a sealing gasket, or other structures that meet the requirements. This invention does not make any specific limitations.

[0105] It is understood that the first sealing element 250 can be disposed alone in the upper shell 220 or the lower shell 210, or it can be disposed in both the upper shell 220 and the lower shell 210, as shown in some specific embodiments provided by the present invention. Figure 9 and Figure 10 As shown, the first seal 250 is disposed on the upper shell 220. Specifically, the first seal 250 is embedded in the upper shell 220.

[0106] In the above embodiments, such as Figure 9 , Figure 10 and Figure 11 As shown, one of the upper shell 220 and the lower shell 210 is provided with a fastening part 222, and the other is provided with a limiting structure 215. The fastening part 222 is rotatably connected to the upper shell 220 or the lower shell 210. By rotating the fastening part 222 to engage with the limiting structure 215, the upper shell 220 and the lower shell 210 can be locked, thereby making the upper shell 220 and the lower shell 210 tightly and reliably connected. By rotating the fastening part 222 to separate from the limiting structure 215, the upper shell 220 and the lower shell 210 can be unlocked, thereby allowing the upper shell 220 to open the opening of the lower shell 210. The operation is simple.

[0107] It is understandable that when the first sealing element 250 is provided between the upper shell 220 and the lower shell 210, the first sealing element 250 can be pressed between the upper shell 220 and the lower shell 210 when the fastening part 222 rotates to engage with the limiting structure 215, that is, when the upper shell 220 and the lower shell 210 are locked, thereby improving the sealing performance of the connection between the upper shell 220 and the lower shell 210.

[0108] Specifically, the different arrangement positions of the buckling part 222 and the limiting structure 215 can meet the requirements of different structures of the buckling part 222 and the limiting structure 215, and expand the use range of the product. For example, in some specific embodiments provided by the present application, as shown in Figure 9 and Figure 10 the buckling part 222 is arranged on the upper shell 220, the limiting structure 215 is arranged on the lower shell 210, the limiting structure 215 is a clamping groove, the buckling part 222 is provided with a clamping hook matched with the clamping groove, and the locking and unlocking of the buckling part 222 and the limiting structure 215 are realized by matching the clamping hook with the clamping groove. The structure is simple, easy to process, and conducive to reducing the manufacturing cost.

[0109] In some possible implemented embodiments provided by the present application, as shown in Figure 9 and Figure 10 the water tank assembly 200 further comprises an upper cover 260 and a second sealing member 270, the upper shell 220 is provided with a liquid injection port 221, the upper cover 260 is adapted to be connected or separated from the upper shell 220, and can cover or open the liquid injection port 221, so that after the upper cover 260 opens the liquid injection port 221, liquid can be injected or poured into the closed space formed by the upper shell 220 and the lower shell 210 through the liquid injection port 221, so as to contain the liquid in the closed space formed by the upper shell 220 and the lower shell 210. When the injection or pouring of liquid is completed, the upper cover 260 covers the liquid injection port 221. This arrangement is particularly conducive to injecting water into the water tank assembly 200. Through this arrangement, the user can complete the water injection of the water tank assembly 200 without opening the upper shell 220, which is conducive to improving the cleanliness of the liquid contained in the closed space, and further conducive to improving the quality of the liquid.

[0110] The second sealing member 270 can be arranged on at least one of the upper cover 260 and the upper shell 220, so that when the upper cover 260 covers the liquid injection port 221, the gap between the upper cover 260 and the upper shell 220 is sealed, and the sealing performance of the closed space formed by the upper shell 220 and the lower shell 210 is ensured, so that the liquid in the closed space will not overflow or leak from the gap between the upper shell 220 and the upper cover 260, and the sealing performance of the water tank assembly 200 is ensured.

[0111] Further, the second sealing member 270 can be an elastic member, and the elastic second sealing member 270 is conducive to improving the sealing performance of the connection between the upper shell 220 and the upper cover 260. Specifically, the second sealing member 270 is a sealing ring, a sealing gasket or other structure meeting the requirements, which is not limited in the present application. It can be understood that the second sealing member 270 can be arranged on the upper shell 220 or the upper cover 260, or can be arranged on both the upper shell 220 and the upper cover 260. In some specific embodiments provided by the present application, as shown in Figure 10 the second sealing member 270 is arranged on the upper cover 260, and specifically, the first sealing member 250 is embedded and connected on the upper cover 260.

[0112] In the above embodiment, as shown in Figure 10 The water tank assembly 200 further comprises a coupling device, which comprises a first coupling part 261 arranged on the upper cover 260 and a second coupling part arranged on the upper shell 220. The first coupling part 261 and the second coupling part are coupled to enable the upper cover 260 to cover the liquid injection port 221, and the first coupling part 261 and the second coupling part are decoupled to enable the upper cover 260 to open the liquid injection port 221. That is, the connection mode of the upper cover 260 and the upper shell 220 is realized by the coupling device.

[0113] Further, the coupling device is a screw mechanism or a sliding mechanism, which can ensure that the upper cover 260 and the upper shell 220 have a reasonable interference fit amount, avoiding the problems that in the related art, the upper cover is directly pressed into the upper shell, and the interference fit amount is small, which leads to poor sealing, or the interference fit amount is large, which is not convenient for taking the upper cover off the upper shell. That is, in the embodiment of the present application, the upper cover 260 and the upper shell 220 are connected by the coupling device of the screw mechanism or the sliding mechanism, which can not only ensure the sealing of the connection between the upper cover 260 and the upper shell 220, but also facilitate the removal of the upper cover 260 from the upper shell 220, and the structure is simple and easy to operate.

[0114] Specifically, for example, the first coupling part 261 comprises a screw protrusion arranged on the outer wall of the upper cover 260, and the second coupling part comprises a screw groove arranged on the inner wall of the upper shell 220. The screw mechanism formed by the screw protrusion and the screw groove enables the upper cover 260 to be connected with the upper shell 220 by screwing, or the upper cover 260 to be detached from the upper shell 220. Alternatively, the first coupling part 261 comprises a sliding block arranged on the outer wall of the upper cover 260, and the second coupling part comprises a sliding groove arranged on the inner wall of the upper shell 220. The sliding mechanism formed by the sliding groove and the sliding block enables the upper cover 260 to be connected with the upper shell 220 by screwing after the upper cover 260 is placed into the liquid injection port 221, or the upper cover 260 to be detached from the upper shell 220 by reversing the screwing of the upper cover 260 and then extracting the upper cover 260, which is simple to operate. It can be understood that the screw mechanism and the sliding mechanism can also be other structures that meet the requirements, which are not limited in the present application.

The drainage device 280 can comprise a driving part 281 and a connecting pipe 282, the connecting pipe 282 being in communication with the inside of the lower shell 210 and the external environment, for example, the cleaning device and the water injection device of the base station. The driving part 281 is arranged on the connecting pipe 282 and is used to drive the liquid in the lower shell 210 to be discharged to the external environment through the connecting pipe 282. In other embodiments of the present application, the drainage device 280 can further comprise a filtering part 293, which can be arranged on at least one of the driving part 281 and the connecting pipe 282. The filtering part 293 can filter the liquid discharged through the connecting pipe 282, effectively filter the impurities in the liquid in the water tank, and thus improve the cleanliness of the liquid discharged to the external environment, avoid damage to the external system (such as the cleaning device or the water injection device of the base station), and be beneficial to improving the reliability of the component to be cleaned.

[0116] Further, different arrangement positions of the filtering part 293 can meet the requirements of different structures of the filtering part 293. Specifically, the filtering part 293 can be arranged on the side of the water inlet end of the connecting pipe 282 away from the water outlet end, wherein the water inlet end is located in the inside of the lower shell 210 and the water outlet end is in communication with the external environment. In this way, it is beneficial to avoid the impurities from blocking the water inlet pipe. The filtering part 293 can be a filter screen, filter cotton or other filter structure meeting the requirements. It can be understood that the upper shell 220 is provided with a drainage port, and the water outlet end of the connecting pipe 282 is in communication with the drainage port.
