Description

Technical Field

[0001] This disclosure belongs to the field of clean technology, specifically relating to a clean base station and a clean system. Background Technology

[0002] Currently, cleaning base stations used with cleaning robots are typically equipped with a container. This container is used to hold recycled dust or waste liquid, or to supply cleaning fluid, etc. The existing container is placed in a slot inside the cleaning base station, and the container and slot are often positioned by their shapes. In this way, users can easily remove the container from the cleaning base station. However, when the cleaning base station is working, if the user is unaware that the cleaning base station is in operation and suddenly removes the container from the cleaning base station, the cleaning base station will report an error. At the same time, some of the cleaning fluid, waste liquid, dust, and other substances in the container will overflow when the interface is suddenly disconnected by external force, contaminating the cleaning base station or the ground and affecting the user experience. Summary of the Invention

[0003] The purpose of this disclosure is to provide a cleaning base station and a cleaning system that can prevent the housing from detaching from the cleaning base station during operation, thereby improving the user experience.

[0004] The first aspect of this disclosure provides a clean base station, comprising:

[0005] The mounting bracket has a placement slot and interface structure;

[0006] A locking structure is movably mounted on the mounting bracket;

[0007] A receiving box having a fastener and a connecting port, the receiving box being installed in the placement slot, the connecting port being connected to the interface structure, and the fastener being opposite to the locking structure;

[0008] The working pump is connected to the interface structure and communicates with the housing through the communication port;

[0009] The controller is connected to the locking structure and the working pump. After receiving the assembly command for the housing to be installed in place and the pump to work command, the controller first controls the locking structure to move to the engagement position to engage with the buckle, and then controls the working pump to start.

[0010] In one exemplary embodiment of this disclosure, the cleaning base station further includes a location detection element connected to the controller, the location detection element being used to send the assembly in place instruction to the controller after the housing is installed in place.

[0011] In one exemplary embodiment of this disclosure, the position detection element is a Hall element, which is mounted on the mounting bracket and connected to the controller;

[0012] The housing is equipped with a magnet, which is positioned opposite the Hall element when the housing is in place.

[0013] In one exemplary embodiment of this disclosure, the cleaning base station further includes an unlock button, which is mounted on the mounting bracket and connected to the controller. The controller is used to control the working pump to stop working when it receives an unlock command from the unlock button, and also controls the locking structure to move to an unlocked position that is separated from the latch.

[0014] In one exemplary embodiment of this disclosure, the unlock button includes a button and a trigger switch, the trigger switch is connected to the controller, and the button is opposite to the trigger switch;

[0015] The trigger switch is used to generate an unlock command and send it to the controller when the button is subjected to external force and is pressed against the trigger switch.

[0016] In one exemplary embodiment of this disclosure, the locking structure includes a fixed base, an electromagnet, and a latch. The fixed base is fixedly mounted on the mounting bracket, the electromagnet is fixedly mounted on the fixed base, and the latch is movably mounted on the fixed base.

[0017] The controller is connected to the electromagnet. After receiving the assembly command and the pump operation command, the controller controls the electromagnet to be energized to generate a working magnetic field, so that the latch moves to the engagement position where it engages with the latch under the action of the working magnetic field. After receiving the unlocking command, the controller controls the electromagnet to be de-energized, so that the latch moves to the unlocking position where it is separated from the latch.

[0018] In one exemplary embodiment of this disclosure, the latch includes a latch body and a connecting shaft.

[0019] The buckle body has a buckling part, a connecting part and a mating part arranged in sequence, and the connecting part is mounted to the fixed base via a mounting shaft;

[0020] The connecting shaft is disposed opposite to the mating part and is surrounded by the electromagnet. The connecting shaft can move axially relative to the electromagnet.

[0021] The connecting shaft can move axially towards the mating part under the action of the working magnetic field, and drive the mating part to rotate the buckle body around the mounting shaft, so that the buckling part rotates to the buckling position to engage with the buckle.

[0022] In an exemplary embodiment of this disclosure, the fixing base is provided with a fixing groove, the electromagnet is located in the fixing groove, and the groove opening is covered with a fixing cover. The fixing base is also provided with a clearance opening that communicates with the fixing groove and is opposite to the mating part. The clearance opening is used for the connecting shaft to pass through so as to contact the mating part.

[0023] The linkage shaft is connected to the electromagnet via a first elastic reset member, and the buckle body is connected to the fixed cover via a second elastic reset member.

[0024] In one exemplary embodiment of this disclosure, the opening of the placement slot faces upward, and the depth of the placement slot is less than the height of the receiving box; wherein,

[0025] An installation platform protrudes from one side of the placement slot, and the interface structure protrudes from the top of the installation platform;

[0026] The side of the container has an overlapping protrusion, and the communication port is located at the bottom of the overlapping protrusion. When the container is vertically inserted into the placement slot, the overlapping protrusion is supported on the top of the installation platform, and the communication port is connected to the interface structure.

[0027] In one exemplary embodiment of this disclosure, one of the top of the mounting platform and the bottom of the overlapping boss is provided with a positioning protrusion, and the other is provided with a positioning groove. The positioning protrusion is inserted into the positioning groove when the receiving box is vertically inserted into the placement slot.

[0028] In one exemplary embodiment of this disclosure, the top of the installation platform is provided with the positioning protrusion, and the bottom of the overlapping protrusion is provided with the positioning groove, wherein the height of the positioning protrusion is greater than the height of the interface structure.

[0029] A second aspect of this disclosure provides a cleaning system comprising: a cleaning robot and a cleaning base station as described in any of the preceding claims, wherein the mounting bracket further comprises a docking base, and a docking space for the cleaning robot to dock is formed between the docking base and the bottom of the placement slot.

[0030] The disclosed solution has the following beneficial effects:

[0031] After receiving the assembly command for the housing and the pump start command, the controller first controls the locking structure to engage with the latch, locking the housing onto the mounting frame. Then, it starts the pump. In other words, after the housing is installed but before the pump starts, the housing and mounting frame are locked together by the locking structure, preventing the housing from being removed from the placement slot. This prevents the housing from detaching from the cleaning base station when the pump is started, thus avoiding any spillage of cleaning fluid, dirt, or dust from contaminating the cleaning base station or the ground if the interface is suddenly disconnected by external force, improving the user experience.

[0032] Other features and advantages of this disclosure will become apparent from the following detailed description, or may be learned in part from practice of this disclosure.

[0033] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0057] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be more thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art.

[0058] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this disclosure. However, those skilled in the art will recognize that the technical solutions of this disclosure can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this disclosure.

[0059] In this disclosure, unless otherwise expressly specified and limited, the term "connection" and other such terms should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0060] like Figure 1 As shown, this embodiment of the present disclosure provides a cleaning base station 1, which can be used in a cleaning system and is used in conjunction with a cleaning robot.

[0061] Combination Figure 1 and Figure 2As shown, the cleaning base station 1 may include a mounting frame 10, a housing 11, and a working pump (not shown in the figure). Combined with... Figure 2 and Figure 3 As shown, the mounting bracket 10 may have a placement slot 101 and an interface structure 102, see reference. Figure 4 As shown, the container 11 has a communication port 110. The container 11 can be installed in the placement slot 101. When the container 11 is installed in the placement slot 101, the communication port 110 of the container 11 can be connected to the interface structure 102. The working pump can be connected to the interface structure 102 and communicate with the inside of the container 11 through the communication port 110. When the working pump is started, the working pump can pump external substances into the inside of the container 11 or pump the substances inside the container 11 to the outside of the container 11.

[0062] For example, when the container 11 is a clean water tank, that is, when the container 11 is used to hold clean water, this working pump can be a water pump. When the water pump is started, the clean water in the container 11 can be pumped to a designated location through the connecting port 110 and the interface structure 102 in sequence under the action of the water pump. For example, it can be pumped to the cleaning robot's mop waiting to be cleaned through the pipeline, and / or pumped to the cleaning robot's liquid storage tank through the pipeline. When the container 11 is a sewage tank or a dust collection tank, that is, when the container 11 is used to contain sewage or dust, the working pump can be an air pump. At this time, the container 11 can be provided with two connection ports, one is an air outlet and the other is an inlet. The air outlet can be connected to the air pump through the interface structure 102 of the mounting bracket 10. The inlet can be connected to a designated position through a pipe or other structure, for example, opposite to the sewage collection tank or dust collection tank of the cleaning base station 1. When the air pump is started, the gas in the sewage tank or dust collection tank can be pumped to the outside of the tank through the air outlet and the interface structure 102 in sequence under the action of the air pump. At this time, a negative pressure is formed inside the tank. Under the action of the negative pressure, the sewage in the sewage collection tank or the dust in the dust collection tank can enter the tank through the inlet.

[0063] The clean base station 1 may also have multiple housing boxes 11, for example: Figure 1 and Figure 2 The two shown can be a clean water tank 11a and a wastewater tank 11b. Correspondingly, the mounting bracket 10 can also be provided with two placement slots 101, one placement slot 101 for placing the clean water tank 11a and the other placement slot 101 for placing the wastewater tank 11b.

[0064] In this embodiment, the opening of the placement slot 101 faces upward, and the receiving box 11 can be perpendicular to the opening (i.e., along the...). Figure 2 (The direction indicated by the hollow thick arrow in the image) is placed into the placement slot 101, wherein, reference Figure 1 and Figure 2As shown, the depth of the placement slot 101 is less than the height of the housing 11, meaning that part of the housing 11 is exposed. This saves material on the mounting bracket 10, thereby reducing the cost of cleaning the base station 1. In addition, when the housing 11 is a transparent housing, it is more convenient for users to observe the usage of the housing 11 in real time.

[0065] For example, such as Figure 2 As shown, a mounting platform 103 protrudes from one side of the placement slot 101, and an interface structure 102 protrudes from the top of the mounting platform 103, and references... Figure 4 As shown, the side of the container 11 has an overlapping protrusion 111, and the connecting port 110 is located at the bottom of the overlapping protrusion 111 and communicates with the interior of the container 11. When the container 11 is vertically inserted into the placement slot 101, the overlapping protrusion 111 is supported on the top of the mounting platform 103, and the connecting port 110 is connected to the interface structure 102. By setting the interface structure 102 on the top of the mounting platform 103, the connecting port 110 of the container 11 can be set at a higher position in the container, reducing the possibility of leakage of the contents of the container through the connecting port 110.

[0066] For example, in order to ensure the airtight connection between the connection port 110 and the interface structure 102, the connection port 110 needs to be interference-fitted with the interface structure 102. Specifically, the interface structure 102 can be set as a soft rubber structure.

[0067] In addition, in order to avoid the working pump occupying the installation space of the housing 11, the working pump in this embodiment can be located on the side of the mounting platform 103 away from the placement slot 101.

[0068] Furthermore, combined Figures 2 to 4 As shown, one of the top of the mounting platform 103 and the bottom of the overlapping boss 111 may be provided with a positioning protrusion 104, and the other may be provided with a positioning groove 112. When the receiving box 11 is vertically inserted into the placement slot 101, the positioning protrusion 104 is inserted into the positioning groove 112. Through the cooperation of the positioning protrusion 104 and the positioning groove 112, the receiving box 11 can be accurately positioned, and the receiving box 11 can also be prevented from swaying left and right relative to the mounting frame 10, thus ensuring the assembly stability of the receiving box 11 and the mounting frame 10.

[0069] In one specific embodiment of this disclosure, such as Figure 2 and Figure 3 As shown, the top of the mounting platform 103 may be provided with a positioning protrusion 104, such as... Figure 4 As shown, a positioning groove 112 may be provided at the bottom of the overlapping boss 111.

[0070] Based on this, refer to Figure 3As shown, the height of the positioning protrusion 104 can be designed to be greater than the height of the interface structure 102. In this way, when the housing 11 is vertically inserted into the placement slot 101, the positioning protrusion 104 and the positioning groove 112 are first interlocked to achieve positioning between the housing 11 and the mounting bracket 10. Then, the interface structure 102 is interlocked with the communication port 110. This can play an assembly protection role for the interface structure 102 and avoid damage to the interface structure 102 during blind insertion.

[0071] For example, see reference Figure 3 As shown, the cross-sectional area of ​​the positioning protrusion 104 can gradually decrease along the direction from its top to its bottom, so that the outer side of the positioning protrusion 104 can be formed as a guide slope to play a certain guiding role, so as to facilitate the positioning groove 112 to be inserted into the placement groove 101 when the receiving box 11 is vertically inserted into the placement groove 101.

[0072] In this embodiment, as Figure 5 As shown, the cleaning base station 1 may also include a locking structure 12 and a controller 13. The locking structure 12 can be movably mounted on the mounting frame 10, such as... Figure 4 As shown, the housing 11 also has a latch 113. When the housing 11 is installed in the placement slot 101, the latch 113 of the housing 11 can be opposite to the locking structure 12. The controller 13 can be connected to the locking structure 12 and the working pump. After receiving the assembly positioning command of the housing 11 and the pump working command, the controller 13 can first control the locking structure 12 to move to the latching position that is engaged with the latch 113, and then control the working pump to start.

[0073] In other words, after the housing 11 is installed in place and before the working pump is started, the housing 11 and the mounting bracket 10 are locked together by the locking structure 12 and the latch 113, and the housing 11 cannot be taken out of the placement slot 101. In this way, when the working pump is started to put the cleaning base station 1 into working state, the housing 11 can be prevented from falling out of the placement slot 101 of the cleaning base station 1. This can prevent the cleaning liquid, dirt, dust and other substances in the housing 11 from overflowing and contaminating the cleaning base station 1 or the ground when the interface is suddenly disconnected by external force, thus improving the user experience.

[0074] For example, the locking structure 12 can be an electromagnetic lock to facilitate control by the controller 13. Specifically, refer to... Figure 6 and Figure 7 As shown, the locking structure 12 may include a fixing base 120, an electromagnet 121, and a locking latch 122. The fixing base 120 is fixedly mounted on the mounting bracket 10, for example, referring to... Figure 5As shown, the fixed base 120 can be fixedly connected to the mounting bracket 10 by fasteners such as screws, the electromagnet 121 is fixedly installed on the fixed base 120, and the latch 122 is movably installed on the fixed base 120.

[0075] The controller 13 can be connected to the electromagnet 121, specifically to the coil of the electromagnet 121. After receiving the assembly command and the pump operation command, the controller 13 controls the electromagnet 121 to be energized, that is, to energize the coil of the electromagnet 121, thereby causing the electromagnet 121 to generate a working magnetic field, which in turn causes the latch 122 to move to the latching position that engages with the latch 113 under the action of the working magnetic field generated by the electromagnet 121.

[0076] In addition, the controller 13 is used to control the electromagnet 121 to be de-energized after receiving the unlocking command. At this time, the working magnetic field disappears, so that the latch 122 can move to the unlocked position separated from the latch 113, so that the user can take the housing 11 out of the placement slot 101.

[0077] Among them, reference Figure 6 and Figure 7 As shown, the latch 122 may include a latch body 1221 and a connecting shaft 1222. The latch body 1221 has a latching part 12210, a connecting part 12211 and a mating part 12212 arranged in sequence. The connecting part 12211 can be mounted on the fixed base 120 via the mounting shaft 123. It should be understood that the latch 122 can rotate around the mounting shaft 123 within a certain angle range. The connecting shaft 1222 is arranged opposite to the mating part 12212 and is surrounded by the electromagnet 121. That is, the electromagnet 121 is arranged around the connecting shaft 1222, and the connecting shaft 1222 can move axially relative to the electromagnet 121.

[0078] Specifically, controller 13 controls the coil of electromagnet 121 to be energized (see reference). Figure 8 In the state shown, the linkage shaft 1222 can move axially towards the mating part 12212 under the action of the working magnetic field generated by the electromagnet 121, and by pushing the mating part 12212, it drives the buckle body 1221 to rotate around the mounting shaft 123, thereby causing the buckling part 12210 to rotate to the buckling position that engages with the buckle 113. (Refer to...) Figure 9 As shown. Controller 13 controls the coil of electromagnet 121 to be de-energized (see reference). Figure 10 When the state shown is reached, the working magnetic field disappears, the linkage shaft 1222 can move axially away from the mating part 12212, and the locking part 12210 rotates to the unlocked position separated from the locking position 113. (Refer to...) Figure 11 As shown.

[0079] It should be understood that when the coil of electromagnet 121 is de-energized, the connecting shaft 1222 and the mating part 12212 can be in a clearance fit, as shown in the reference. Figure 10 As shown, this means that the two are not in contact, or even if they are in contact, the contact force is not strong.

[0080] In this embodiment, by converting the axial movement of the connecting shaft 1222 into the rotation of the buckle body 1221, the axial movement distance of the connecting shaft 1222 can be shortened while controlling the buckling part 12210 of the buckle body 1221 to switch between the unlocked and buckled positions. This reduces the working space occupied by the connecting shaft 1222. In addition, this design can also prevent the electromagnet 121 and the connecting shaft 1222 from occupying the installation space of the housing 11.

[0081] For example, refer to Figure 4 As shown, the outer wall of the receiving box 11 may be provided with a fastener 113, which may be located below the overlapping boss 111, while the locking structure 12 may be provided on the side of the mounting platform 103 away from the placement groove 101, as shown in the reference. Figure 3 As shown, the mounting platform 103 may also be provided with a mating through hole 1031 that is opposite to the buckle 113 when the housing 11 is installed in the placement slot 101. When the electromagnet 121 is energized, the fastening part 12210 can rotate to the mating through hole 1031 and pass through the mating through hole 1031 to fasten with the buckle 113. When the electromagnet 121 is de-energized, the fastening part 12210 rotates out from the mating through hole 1031 or rotates out into the interior of the mating through hole 1031 to separate from the buckle 113.

[0082] In addition, such as Figure 5 As shown, the controller 13 can also be located on the side of the mounting platform 103 away from the placement slot 101, so as to avoid the controller 13 occupying the installation space of the housing 11.

[0083] For example, see reference Figure 3 As shown, the top area of ​​the mounting platform 103 is provided with a positioning notch 1032. The side wall of the positioning notch 1032 is provided with the aforementioned mating through hole 1031. When the receiving box 11 is inserted into the placement slot 101, the buckle 113 can be inserted into the positioning notch 1032. This can further prevent the receiving box 11 from shaking on the mounting frame 10, and also facilitate the positioning and engagement of the buckling part 12210 of the buckle body 1221 with the buckle 113.

[0084] In this embodiment, as Figure 7As shown, the mounting base 120 may be provided with a mounting groove 1201, and the electromagnet 121 is located in the mounting groove 1201. For example, the mounting groove 1201 can be positioned with the electromagnet 121 by its shape. A mounting cover 124 is provided at the opening of the mounting groove 1201. For example, after the electromagnet 121 is positioned in the mounting groove 1201 through the opening, the mounting cover 124 can be fixed to the mounting base 120 by fasteners such as screws 125. This mounting cover 124 covers the opening of the mounting groove 1201. The mounting cover 124 and the mounting groove 1201 of the mounting base 120 work together to fix the electromagnet 121.

[0085] It should be understood that, such as Figure 7 As shown, the fixed base 120 is also provided with a clearance opening 1202 that communicates with the fixed groove 1201 and is opposite to the mating part 12212. The clearance opening 1202 is used for the connecting shaft 1222 to pass through so that it can contact the mating part 12212. Furthermore, the side of the fixed groove 1201 away from the mating part 12212 may also be provided with a clearance opening 1202 that communicates with the fixed groove 1201, so as to ensure that the connecting shaft 1222 has a large range of movement in the axial direction.

[0086] Among them, reference Figure 6 and Figure 7 As shown, the linkage shaft 1222 can be connected to the electromagnet 121 via the first elastic reset member 126. Specifically, the first elastic reset member 126 can be a spring, which is located inside the electromagnet 121 and sleeved on the linkage shaft 1222. The buckle body 1221 is connected to the fixing cover 124 via the second elastic reset member 127. The second elastic reset member 127 can be a tension spring. Specifically, the buckle body 1221 has a groove with coaxial through holes on both sides of the groove. A first tension spring shaft 128 is installed in the coaxial through holes. One end of the tension spring is installed on the first tension spring shaft 128 of the buckle body 1221. A second tension spring shaft 129 is set on the fixing cover 124 in the same way, and the other end of the tension spring is installed on the second tension spring shaft 129 of the fixing cover 124, thereby realizing the connection between the tension spring and the buckle body 1221 and the fixing cover 124.

[0087] In this embodiment, when the coil of the electromagnet 121 is de-energized, the connecting shaft 1222 does not contact the mating part 12212 of the buckle body 1221 or the contact force is small. When the coil of the electromagnet 121 is energized, the electromagnet 121 attracts, compresses the first elastic reset member 126, overcomes the spring force, and pushes the connecting shaft 1222 toward the position of the mating part 12212 of the buckle body 1221, thus driving the buckle body 1221 to rotate around the mounting shaft 123, thereby causing the buckling part 12210 to rotate to the position of the buckle body 12212. When the latch 113 is engaged, the second elastic reset member 127 is in a stretched state. When the coil of the electromagnet 121 is de-energized, the working magnetic field disappears, the first elastic reset member 126 recovers its deformation, and drives the connecting shaft 1222 to move axially away from the mating part 12212 to the initial position, that is, drives the connecting shaft 1222 to reset. At this time, the second elastic reset member 127 recovers its deformation and pulls the latching part 12210 to rotate to the unlocking position separated from the latch 113, that is, pulls the latch body 1221 to reset.

[0088] The aforementioned controller 13 is used to control the electromagnet 121 to be de-energized after receiving an unlock command. It should be understood that this unlock command can be automatically generated after the working pump completes its work, or it can be a user-triggered command. When the unlock command is user-triggered, it should be combined with… Figure 1 , Figure 2 and Figure 12 As shown, the cleaning base station 1 in this embodiment may also include an unlock button 14. The unlock button 14 can be installed on the mounting bracket 10 and connected to the controller 13. The controller 13 is used to control the working pump to stop working when it receives the unlock command issued by the unlock button 14, and also controls the locking structure 12 to move to the unlock position separated from the latch 113.

[0089] For example, when the cleaning base station 1 is in operation, that is, after the working pump is started, if there is a sudden need to remove the container 11, the user can trigger the unlock button 14. At this time, the unlock button 14 will generate an unlock command and send it to the controller 13. When the controller 13 receives the unlock command from the unlock button 14, it controls the working pump to stop working and controls the locking structure 12 to move to the unlock position separated from the latch 113. It should be understood that the controller 13 can simultaneously control the working pump to stop and control the locking structure 12 to move to the unlock position, but it is not limited to this. It can also control the working pump to stop first and then control the locking structure 12 to move to the unlock position, or control the locking structure 12 to move to the unlock position first and then control the working pump to stop.

[0090] In this embodiment, the controller 13 can preferably control the working pump to stop and control the locking structure 12 to move to the unlock position when it receives the unlock command from the unlock button 14. This allows the user to quickly remove the container 11 from the placement slot 101 in case of an emergency.

[0091] In this embodiment, it is also preferable that when the controller 13 receives the unlocking command from the unlocking button 14, it first controls the working pump to stop, and then controls the locking structure 12 to move to the unlocking position. This can prevent the housing 11 and the mounting bracket 10 from being in the unlocked state before the working pump has stopped working, which would cause the housing 11 to shake or fall off the placement slot 101 while the working pump is still working.

[0092] For example, such as Figure 12 As shown, the unlock button 14 in this embodiment may include a button 140 and a trigger switch 141. The trigger switch 141 is connected to the controller 13, and the button 140 is opposite to the trigger switch 141. The trigger switch 141 is used to generate an unlock command and send it to the controller 13 when the button 140 is subjected to external force and is pressed against the trigger switch 141. In other words, the unlock button 14 in this embodiment can be a press-type button, which is simple in structure and easy to operate.

[0093] It should be noted that, such as Figure 12 As shown, the trigger switch 141 can be mounted on the circuit board 142, which can be fixedly mounted on the mounting bracket 10. The trigger switch 141 can be connected to the controller 13 through the circuit board 142. The button 140 can be fixedly mounted on the mounting bracket 10 by screws or other fasteners. The button 140 can have a certain deformation capability. When the button 140 is subjected to external force, the button 140 deforms and is pressed against the trigger switch 141. When the external force on the button 140 is removed, the button 140 restores its deformation and can maintain a distance from the trigger switch 141.

[0094] It should be noted that the unlock button 14 is not limited to the aforementioned forms; it can also be a touch-sensitive type, a knob type, or other methods, as long as it can achieve the unlocking function.

[0095] In the case where the clean base station 1 has two housing boxes 11 and the mounting frame 10 is provided with two corresponding placement slots 101, at least two locking structures 12 can be provided, with each housing box 11 cooperating with at least one locking structure 12; Reference Figure 1 and Figure 2 As shown, an unlock button 14 can be provided. This unlock button 14 can be located in the middle of the two placement slots 101 and away from the installation platform 103, so as to facilitate user operation.

[0096] It should be understood that the unlock button 14 is not limited to one, but can also be multiple. Each locking structure 12 corresponding to each container 11 can correspond to one unlock button 14. That is to say, each container 11 can be controlled to unlock or lock separately.

[0097] In embodiments of this disclosure, reference is made to Figure 13 As shown, the cleaning base station 1 may also include a position detection element 15, which can be connected to the controller 13. The position detection element 15 is used to send an assembly command to the controller 13 after the housing box 11 is installed in place. By setting the position detection element 15, it is possible to more accurately monitor whether the housing box 11 is installed in place at the placement slot 101.

[0098] The position detection element 15 can be a Hall element, which can be installed on the mounting bracket 10 and connected to the controller 13; while the housing 11 can be provided with a magnet 114. When the housing 11 is installed in place, the magnet 114 is opposite to the Hall element. At this time, the Hall element can generate an assembly in place command and send it to the controller 13. This detection method is simple, low in cost, and easy to design.

[0099] For example, refer to Figure 4 As shown, the magnet 114 can be disposed at the bottom of the overlapping boss 111 of the receiving box 11, while the Hall element can be disposed at the top of the mounting platform 103 and located on the side of the mounting platform 103 away from the overlapping boss 111. When the receiving box 11 is inserted into the placement slot 101, the overlapping boss 111 is supported on the mounting platform 103, and the magnet 114 is opposite to the Hall element.

[0100] Based on the aforementioned structure, it can be combined with Figure 14The circuit diagram shown illustrates the working principle of this embodiment. When the housing 11 is inserted into the placement slot 101 and installed in place, the position detection element 15 generates an assembly in place command. Based on this assembly in place command, the controller 13 controls the switch SB1 to change from normally open to normally closed and outputs a high potential. It should be understood that this switch SB1 is the switch corresponding to the housing 11 in place detection. After the housing 11 is installed in place, before the cleaning base station 1 starts working, that is, before the working pump starts, the controller 13 will send a locking signal for the cleaning base station 1. This locking signal is at a high level. When the switch SB2 receives this locking signal, it closes. At this time, the coil KM1 of the electromagnet 121 is energized and self-locks. That is to say, after the coil KM1 of the electromagnet 121 is energized, the electromagnet 121 is attracted, driving the connecting shaft 1222 to move vertically in its axis, thereby driving the buckle body 1221 to rotate, so that the buckling part 12210 rotates to the buckling position (i.e., the locking position) that is engaged with the buckle 113 of the housing 11. After the coil KM1 of electromagnet 121 is energized, putting electromagnet 121 into the working position, controller 13 receives a working start signal (i.e., pump working command). This pump working command is high level. Based on this pump working command, controller 13 controls switch SB4 to change from normally open to normally closed, energizing the coil KM2 of the working pump to start the working pump. When the unlock button 14 of the housing 11 is pressed, controller 13 receives an unlock command and outputs an unlock signal. This unlock signal is high level, controlling switch SB3 to change from normally closed to normally open. The coil KM1 of electromagnet 121 is disconnected, and the coil KM2 of the working pump is disconnected. At this time, both electromagnet 121 and the working pump stop working. After electromagnet 121 stops working, the linkage shaft 1222 is reset under the action of the first elastic reset member 126, and the buckle 1221 is reset under the action of the second elastic reset member 127, so that the buckle part 12210 rotates to the unlock position separated from the buckle position 113 of the housing 11.

[0101] In this embodiment, reference Figure 1 and Figure 3 As shown, the mounting bracket 10 may also have a docking base 105, and a docking space for the cleaning robot to dock is formed between the docking base 105 and the bottom of the placement slot 101.

[0102] The cleaning base station 1 can also be equipped with a power supply structure (not shown in the figure). This power supply structure can connect with the structure to be charged on the cleaning robot when the cleaning robot is docked on the docking base 105, so as to charge the structure to be charged on the cleaning robot.

[0103] This disclosure also provides a cleaning system, including: a cleaning robot (not shown in the figure) and a cleaning base station 1 of any of the above. For example, the cleaning robot in this embodiment may be a mopping or washing robot. At least a portion of this cleaning robot can be axially moved to the docking base 105 of the cleaning base station 1 and located in the docking space.
