The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0036] The device assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0037] like Figures 1 to 7 As shown, according to an embodiment of the utility model, the equipment component 100 includes a first device 10 and a second device 20. The first device 10 includes a pipeline component and a control valve 12. The control valve 12 is arranged on the pipeline component for controlling the pipeline component. For example, the connection, cutoff, etc. of the pipeline component can be controlled by the control valve 12. The first device 10 and the second device 20 can be detachably matched. The second device 20 includes a trigger member 21. When the first device 10 and the second device 20 are matched, the trigger member 21 triggers the control valve 12 to switch to a first state. When the first device 10 and the second device 20 are disengaged, the control valve 12 is in a second state, which is different from the first state.

[0038] That is to say, the trigger 21 is used to control the control valve 12 to switch from the second state to the first state. The control valve 12 is often in the second state when it is not matched with the trigger 21. When the control valve 12 is matched with the first device 10 and the second device 20, the trigger 21 can automatically match with the control valve 12 to switch the control valve 12 from the second state to the first state; after the first device 10 and the second device 20 are disengaged, the matching of the trigger 21 and the control valve 12 is released at the same time, and the control valve 12 switches from the first state to the second state after losing the trigger of the trigger 21. That is, the control valve 12 can automatically switch between the first state and the second state by matching and separating the first device 10 and the second device 20. As a result, the step of operating the control valve 12 to switch between the first state and the second state can be omitted, which is conducive to improving the efficiency of switching the control valve 12 between the first state and the second state.

[0039] According to the equipment component 100 of the embodiment of the utility model, the second device 20 includes a trigger member 21. When the first device 10 and the second device 20 cooperate, the trigger member 21 triggers the control valve 12 to switch to the first state. When the first device 10 and the second device 20 are disengaged, the control valve 12 is in the second state. The step of separately operating the control valve 12 to switch between the first state and the second state can be omitted, which is beneficial to improving the efficiency of switching the control valve 12 between the first state and the second state.

[0040] According to some embodiments of the present invention, when the first device 10 and the second device 20 are matched, the trigger 21 and the control valve 12 are arranged relative to each other. Thus, the difficulty of matching the trigger 21 and the control valve 12 can be reduced, which is conducive to improving the stability of the trigger 21 triggering the control valve 12. In a specific example, the trigger 21 and the control valve 12 are arranged relative to each other along the matching direction of the first device 10 and the second device 20.

[0041] According to some embodiments of the utility model, one of the first state and the second state is the on state and the other is the off state. Thus, the control valve 12 can be switched between the on state and the off state by the cooperation and separation of the first device 10 and the second device 20. When the control valve 12 is in the on state, the channels on both sides can be connected so that the material in the channel on one side of the control valve 12 can enter the channel on the other side of the control valve 12 through the control valve 12. When the control valve 12 is in the off state, the communication between the channels connected to the two sides of the control valve 12 is cut off to prevent the material in the channel on one side of the control valve 12 from entering the channel on the other side of the control valve 12 through the control valve 12.

[0042] According to some embodiments of the utility model, the first device 10 includes a storage box 13 and a delivery pump 14, the pipeline assembly includes a first pipeline assembly, the first pipeline assembly is connected to both the storage box 13 and the delivery pump 14, the control valve 12 is arranged on the first pipeline assembly for controlling the first pipeline assembly, the second device 20 includes a supply box 22, the first state is a conduction state, and the second state is a cut-off state. When the first device 10 and the second device 20 cooperate, the delivery pump 14 is used to transport the material in the supply box 22 to the storage box 13 through the first pipeline assembly.

[0043] That is to say, when the first device 10 and the second device 20 cooperate, the supply box 22 can be connected to the storage box 13 through the first pipeline assembly, and the control valve 12 is in a conducting state after being triggered by the trigger member 21, so that the delivery pump 14 can be connected to the supply box 22 through the first pipeline assembly. Therefore, when the delivery pump 14 is running, such as during the suction action, a pressure driving force can be applied to the material in the supply box 22, so that the material in the supply box 22 can enter the storage box 13 along the first pipeline assembly to realize the operation of replenishing the storage box 13; after the first device 10 and the second device 20 are separated, the first pipeline assembly is disconnected from the supply box 22, and the control valve 12 is disconnected from the trigger member 21 and switched to the cut-off state.

[0044] According to some embodiments of the utility model, the control valve 12 includes a valve core 121, and the valve core 121 is movable between a conduction position and a cut-off position. When the first device 10 cooperates with the second device 20, there is a force between the trigger member 21 and the valve core 121 to drive the valve core 121 to move to the conduction position; in the conduction position, the control valve 12 is in a conduction state, and in the cut-off position, the control valve 12 is in a cut-off state. In other words, the control valve 12 is switched between the conduction state and the cut-off state by controlling the movement of the valve core 121 between the conduction position and the cut-off position. The trigger member 21 drives the valve core 121 to move by directly cooperating with the valve core 121, which can reduce the difficulty of the trigger member 21 triggering the control valve 12 to switch to the conduction state, and can simplify the structure of the control valve 21.

[0045] According to some embodiments of the utility model, the control valve 12 includes an elastic reset member 122, one end of the elastic reset member 122 is connected to the first pipeline assembly and the other end is connected to the valve core 121, and the elastic reset member 122 is used to drive the valve core 121 to move to the cut-off position. In other words, the elastic reset member 122 has a tendency to drive the valve core 121 to move toward the cut-off position. Therefore, when the first device 10 is separated from the second device 20, the valve core 121 is often in the cut-off position under the action of the elastic reset member 122. When the first device 10 is matched with the second device 20, the action force between the trigger member 21 and the valve core 121 drives the valve core 121 to overcome the elastic force of the elastic reset member 122, so that the valve core 121 moves from the cut-off position to the conducting position, so as to switch the control valve 12 to the conducting state. When the first device 10 and the second device 20 are disengaged, the force between the trigger 21 and the valve core 121 disappears, that is, the force acting on the valve core 121 to squeeze the elastic reset member 122 disappears, and the elastic reset member 122 recovers its elastic deformation to drive the valve core 121 to move from the conduction position to the cut-off position, so as to switch the control valve 12 to the cut-off state. Therefore, through the cooperation of the valve core 121, the elastic reset member 122 and the trigger 21, the control valve 12 can be better switched to the conduction state when the first device 10 and the second device 20 are matched, and automatically switched to the cut-off state after the first device 10 and the second device 20 are separated, that is, the stability of the control valve 12 switching between the conduction state and the cut-off state can be ensured.

[0046] According to some embodiments of the utility model, there is a magnetic force between the trigger 21 and the valve core 121, which is used to drive the valve core 121 to move to the conduction position. That is to say, after the first device 10 and the second device 20 are matched, a magnetic force of attraction is formed between the trigger 21 and the valve core 121, so that the trigger 21 and the valve core 121 have a tendency to move toward each other. Since the trigger 21 is arranged on the second device 20, the valve core 121 squeezes the elastic reset member 122 under the action of the magnetic force and moves toward the direction close to the trigger 21 until it is in the conduction position; when the first device 10 and the second device 20 are disengaged, the magnetic force between the trigger 21 and the valve core 121 disappears, that is, the thrust of the valve core 121 squeezing the elastic reset member 122 disappears, and the elastic reset member 122 recovers its elastic deformation to drive the valve core 121 to move from the conduction position to the cut-off position. Therefore, by magnetically cooperating with the trigger member 21 and the valve core 121, the movement of the valve core 121 from the on position to the off position can be achieved, which can reduce the difficulty of positioning between the trigger member 21 and the valve core 121. At the same time, the cooperating structure between the trigger member 21 and the valve core 121 can be simplified, which is conducive to reducing the difficulty of the trigger member 21 triggering the control valve 12.

[0047] According to some embodiments of the utility model, at least part of the trigger 21 is composed of a magnet, and at least part of the valve core 121 is made of ferromagnetic material. Among them, the magnet can attract the ferromagnetic material, that is, by the part of the trigger 21 composed of the magnet attracting the part of the valve core 121 composed of the ferromagnetic material, a magnetic force can be formed between the trigger 21 and the valve core 121 to ensure that the trigger 21 can attract the valve core 121 towards the direction close to the trigger 21 when the first device 10 and the second device 20 cooperate to move the control valve 12 to the conducting state. Among them, it should be noted that the trigger 21 can be partially composed of a magnet, or the trigger 21 can be completely composed of a magnet; the valve core 121 can be partially made of a ferromagnetic material, or the valve core 121 can be completely made of a ferromagnetic material, and no specific restrictions are made here.

[0048] According to some embodiments of the utility model, the trigger 21 is a magnet, and the valve core 121 is a steel part. In this way, the cost of the trigger 21 and the valve core 121 can be reduced. At the same time, the durability of the steel part is good, so the service life of the valve core 121 can be improved. It should be noted that here is only an example of a specific material of one of the triggers 21 and the valve core 121 to facilitate understanding of the matching mode of the trigger 21 and the valve core 121, and it is not a limitation on the materials of the trigger 21 and the valve core 121. The materials of the trigger 21 and the valve core 121 can satisfy the requirement that there is a force between the two to move toward each other.

[0049] According to some embodiments of the present invention, the valve core 121 is formed into a spherical shape. Therefore, by setting the valve core 121 into a spherical shape, the valve core 121 is easy to roll in the first pipeline assembly, and the positional deviation of the valve core 121 in the first pipeline assembly can be better avoided, which is conducive to improving the stability and reliability of the control valve 12.

[0050] According to some embodiments of the utility model, the second device 20 includes a supply pipe 23, one end of the supply pipe 23 is connected to the supply box 22 and the other end has a docking joint 2333, the first pipeline assembly has a docking port 1111, and when the first device 10 and the second device 20 are matched, the docking joint 2333 is suitable for being inserted into the docking port 1111. In other words, the supply pipe 23 is suitable for plugging and matching with the first pipeline assembly, and the matching method is simple, which is convenient for connection and separation. Among them, when the first device 10 and the second device 20 are matched, the supply pipe 23 is connected to the first pipeline assembly through the plugging and matching of the docking joint 2333 and the docking port 1111, so that a connected material supply channel is formed between the supply box 22 and the storage box 13 through the connection between the supply pipe 23 and the first pipeline assembly, so that the material in the supply box 22 can enter the storage box 13 through the supply pipe 23 and the part of the first pipeline assembly connecting the supply pipe 23 and the storage box 13 under the drive of the delivery pump 14.

[0051] According to some embodiments of the utility model, the trigger 21 is located above the docking joint 2333. That is, when the first device 10 and the second device 20 are matched, the matching position of the trigger 21 and the control valve 12 is located above the plugging position of the docking joint 2333 and the docking port 1111. As a result, when leakage occurs at the connection position of the docking joint 2333 and the docking port 1111, the leaked material can be prevented from affecting the matching of the trigger 21 and the control valve 12, that is, it is ensured that the trigger 21 can stably trigger the control valve 12 to be in the first state when the first device 10 and the second device 20 are matched, which is conducive to improving the stability of the matching between the trigger 21 and the control valve 12.

[0052] According to some embodiments of the utility model, the other end of the supply pipe 23 has a docking joint 2333 suitable for corresponding to the first device 10, and the docking joint 2333 is located at a height lower than the bottom surface of the supply box 22. In other words, the supply box 22 is located above the docking joint 2333, so that sufficient matching space can be reserved below the supply box 22 for the first device 10 to enter the second device 20, so as to facilitate operations such as cleaning the first device 10 in the second device 20, and the docking joint 2333 is located below the bottom surface of the supply box 22, which is convenient for the docking joint 2333 to dock with the first device 10. For example, the docking joint 2333 can be at approximately the same height as the first device 10, which is conducive to reducing the difficulty of matching and connecting the first device 10 with the docking joint 2333.

[0053] According to some embodiments of the present invention, the control valve 12 and the docking port 1111 are located on the same side of the first device 10. Thus, the difficulty of matching the docking port 1111 and the control valve 12 with the second device 20 can be reduced.

[0054] According to some embodiments of the utility model, the first pipeline assembly includes a feed pipeline 111, an air extraction pipeline 112 and an exhaust pipeline 113, one end of the feed pipeline 111 is connected to the storage box 13 and the other end is formed with a docking port 1111 for docking with the second device 20, one end of the air extraction pipeline 112 is connected to the storage box 13 and the other end is connected to the inlet of the delivery pump 14, the exhaust pipeline 113 is connected to the outlet of the delivery pump 14, and the control valve 12 is provided on the air extraction pipeline 112. That is, when the first device 10 cooperates with the second device 20, the feed pipeline 111 is docked with the second device 20 through the docking port 1111 to communicate with the supply box 22, so that a connected material delivery channel can be formed between the supply box 22 and the storage box 13 through the feed pipeline 111. The delivery pump 14 is connected to the storage box 13 through the air extraction pipeline 112 and is connected between the air extraction pipeline 112 and the exhaust pipeline 113. Therefore, the delivery pump 14 can extract the gas in the storage box 13 through the air extraction pipeline 112 and discharge it through the exhaust pipeline 113. The control valve 12 is arranged in the air extraction pipeline 112 to control the on-off of the air extraction pipeline 112, thereby controlling the connection or cutoff of the delivery pump 14 with the storage box 13 through the air extraction pipeline 112. Therefore, the delivery pump 14 can drive the material in the supply box 22 to enter the storage box 13 through the cooperation of the feed pipeline 111, the air extraction pipeline 112, the exhaust pipeline 113 and the control valve 12.

[0055] Specifically, when the first device 10 and the second device 20 cooperate, the feed pipeline 111 is connected to the second device 20 through the docking port 1111 to communicate with the supply box 22. At this time, the supply box 22 is connected to the storage box 13 through the feed pipeline 111. The trigger 21 triggers the control valve 12 to be in a conducting state, so that the exhaust pipeline 112 is in a conducting state. The inlet of the delivery pump 14 is connected to the storage box 13 through the exhaust pipeline 112. Therefore, the delivery pump 14 can pump the gas in the storage box 13 through the exhaust pipeline 112. The gas is extracted and discharged through the exhaust pipe 113. As the gas in the storage box 13 is continuously discharged, the air pressure value in the storage box 13 also decreases, that is, the storage box 13 can be evacuated with negative pressure through the delivery pump 14. Since a connected material delivery channel is formed between the supply box 22 and the storage box 13, a pressure difference can be formed between the supply box 22 and the storage box 13. Therefore, the material in the supply box 22 can enter the storage box 13 through the feed pipe 111 under the action of the pressure difference, so as to realize the operation of replenishing the material in the storage box 13.

[0056] According to some embodiments of the utility model, an air extraction channel 1121 is formed in the air extraction pipeline 112, part of the outer peripheral wall of the air extraction pipeline 112 protrudes outward to form a convex 1122, and a receiving chamber 1123 connected to the air extraction channel 1121 is formed in the convex 1122, and the control valve 12 includes a valve core 121, and the valve core 121 is movable between a conducting position and a cut-off position, and the trigger member 21 is suitable for driving the valve core 121 to move to the conducting position by applying a force to the valve core 121. In the conducting position, the valve core 121 is located in the receiving chamber 1123 and conducts the air extraction channel 1121, and the control valve 12 is in the conducting state; in the cut-off position, at least part of the valve core 121 is located in the air extraction channel 1121 and blocks the air extraction channel 1121, and the control valve 12 is in the cut-off state. Therefore, the valve core 121 in the conducting position can be better accommodated by the storage chamber 1123, so as to avoid the valve core 121 in the exhaust channel 1121 to generate resistance to the flow of gas, which is beneficial to improving the efficiency of the delivery pump 14 to discharge the gas in the storage box 13.

[0057] According to some embodiments of the utility model, the control valve 12 includes an elastic reset member 122, the elastic reset member 122 is located in the storage chamber 1123, one end of the elastic reset member 122 is connected to the convex bulge 1122 and the other end is connected to the valve core 121, and the elastic reset member 122 is used to drive the valve core 121 to move to the cut-off position. Therefore, by arranging the elastic reset member 122 in the storage chamber 1123, it is possible to better avoid the elastic reset member 122 from blocking the air flow in the air extraction channel 1121, thereby reducing the gas flow resistance in the air extraction pipeline 112, which is conducive to improving the efficiency of the delivery pump 14 in discharging the gas in the storage box 13.

[0058] According to some embodiments of the present invention, the first device 10 is a cleaning device, the second device 20 is a cleaning base station, and the supply tank 22 is used to supply cleaning liquid to the storage tank 13. That is, the first device 10 stores the cleaning liquid through the storage tank 13, and the second device 20 stores the cleaning liquid through the supply tank 22, wherein the first device 10 can clean the floor and the like with the cleaning liquid in the storage tank 13 to improve the cleaning effect of the first device 10. When the cleaning liquid in the storage tank 13 is exhausted, the supply tank 22 can be connected to the storage tank 13 by cooperating with the second device 20, and the cleaning liquid in the supply tank 22 can be driven into the storage tank 13 by the delivery pump 14 to perform the liquid replenishment operation of the storage tank.

[0059] According to some embodiments of the utility model, both the supply tank 22 and the storage tank 13 are used to store cleaning liquid. The second device 20 includes a supply pipe 23 and a functional component 24. The functional component 24 is configured to control the supply tank 22 to stop supplying liquid to the supply pipe 23 and control the cleaning liquid in the supply pipe 23 to flow into at least one of the supply tank 22 and the storage tank 13 when the liquid level in the storage tank 13 reaches a preset liquid level. At this time, the supply tank 22 is connected to the storage tank 13 through the supply pipe 23. Under the drive of the delivery pump 14, the cleaning liquid in the supply tank 22 enters the storage tank 13 through the supply pipe 23, thereby realizing the operation of replenishing the storage tank 13. In the residual liquid discharge mode, the first device 10 cooperates with the second device 20, and the functional component 24 works. At this time, the supply pipe 23 is still connected to the storage tank 13, but the cleaning liquid in the supply tank 22 stops flowing into the storage tank 13 through the supply pipe 23. The functional component 24 works to control the cleaning liquid in the supply pipe 23 to flow into at least one of the storage tank 13 and the supply tank 22, thereby preventing the residual cleaning liquid in the supply pipe 23 from flowing out or causing waste due to the siphon effect.

[0060] According to some embodiments of the utility model, the first device 10 includes a liquid level sensor, which is arranged in the storage box 13. When the first device 10 cooperates with the second device 20, the functional component 24 is electrically connected to the liquid level sensor. The liquid level of the cleaning liquid in the storage box 13 can be accurately obtained through the liquid level sensor. Therefore, in the process of conveying the cleaning liquid to the storage box 13 through the supply pipe 23 through the supply box 22, when the liquid level in the storage box 13 reaches the preset liquid level, since the functional component 24 is electrically connected to the liquid level sensor, the liquid level sensor can transmit the signal that the liquid level in the storage box 13 has reached the preset liquid level to the functional component 24. After receiving the signal, the functional component 24 switches to the working state and cleans the cleaning liquid in the supply pipe 23. Therefore, through the cooperation of the liquid level sensor and the functional component 24, the control signal can be transmitted to the functional component 24 in time after the cleaning liquid in the storage box 13 reaches the preset liquid level, which is conducive to improving the automation level of the device component 100.

[0061] According to some embodiments of the present invention, the functional component 24 includes: a first pump body 241, the first pump body 241 is connected to the supply pipe 23, and the first pump body 241 is configured to deliver gas to the supply pipe 23 when the liquid level in the storage tank 13 reaches a preset liquid level, so that the supply tank 22 stops supplying liquid to the supply pipe 23 and the cleaning liquid in the supply pipe 23 flows into at least one of the storage tank 13 and the supply tank 22. That is, when the liquid level in the storage tank 13 reaches the preset liquid level, the gas delivered to the supply pipe 23 by the first pump body 241 can cut off the flow of the cleaning liquid in the supply pipe 23 to the storage tank 13, and at the same time can push the cleaning liquid in the supply pipe 23 to flow toward the storage tank 13 and / or the supply tank 22 to empty the cleaning liquid in the supply pipe 23. Thus, the cleaning liquid in the supply pipe 23 is emptied by using gas to push the liquid flow, which is low-cost and can better avoid introducing other types of liquids into the supply pipe 23, which is beneficial to improving the reliability of the first pump body 241 in cleaning the cleaning liquid in the supply pipe 23.

[0062] According to some embodiments of the utility model, the supply pipe 23 includes a first pipe section 231, a second pipe section 232 and a third pipe section 233 connected in sequence, the first pipe section 231 extends in the up-down direction, at least a portion of the third pipe section 233 extends in the up-down direction, the second pipe section 232 has an angle with the first pipe section 231 and the third pipe section 233, the lower end of the first pipe section 231 is connected to the supply box 22, the lower end of the third pipe section 233 has a docking joint 2333 suitable for corresponding to the first device 10, the second pipe section 232 is connected to the upper end of the first pipe section 231 and the upper end of the third pipe section 233, and the first pump body 241 is connected to the second pipe section 232.

[0063] That is, the first pipe section 231 and the third pipe section 233 are connected through the second pipe section 232. The end of the first pipe section 231 away from the second pipe section 232 is connected to the supply box 22. The end of the third pipe section 233 away from the second pipe section 232 has a docking joint 2333. The docking joint 2333 is matched with the first device 10 to achieve the connection between the third pipe section 233 and the storage box 13. Therefore, in the residual liquid discharge mode, since the first pump body 241 is connected to the second pipe section 232, the first pump body 241 can transport gas into the second pipe section 232. The gas entering the second pipe section 232 is divided into two parts. One part of the gas flows in the direction close to the first pipe section 231, thereby pushing the cleaning liquid located at the upstream side of the connection position between the first pump body 241 and the second pipe section 232 in the supply pipe 23 to flow into the upper end of the first pipe section 231. The first pipe section 231 extends in the up-down direction, so that the liquid in the first pipe section 231 can be pushed by the gas and gravity. The gas flows downward into the supply box 22 to avoid the cleaning liquid remaining in the first pipe section 231; the other part of the gas flows toward the direction close to the third pipe section 233, thereby pushing the cleaning liquid in the supply pipe 23 located at the downstream side of the connection position between the first pump body 241 and the second pipe section 232 to flow into the upper end of the third pipe section 233. At least the part of the third pipe section 233 connected to the second pipe section 232 extends in the up-down direction, so that the cleaning liquid in the third pipe section 233 can flow downward into the storage box 13 under the push of the gas and the action of gravity, so as to avoid the cleaning liquid remaining in the third pipe section 233. In this way, the cleaning effect of the residual cleaning liquid in the supply pipe 23 can be improved.

[0064] According to some embodiments of the utility model, the second pipe segment 232 extends in a straight line or is formed into an arc that bends upward. Thus, it is possible to better avoid the second pipe segment 232 bending downward, resulting in the cleaning liquid remaining in the second pipe segment 232. In addition, when the second pipe segment 232 is formed into an arc that bends upward, that is, the second pipe segment 232 is low at both ends and high in the middle in the extension direction, the cleaning liquid remaining in the second pipe segment 232 can flow toward the two ends of the second pipe segment 232 under the action of gravity, and further flow into the supply box 22 and the storage box 13 through the first pipe segment 231 and the third pipe segment 233, respectively, to ensure that the cleaning liquid in the second pipe segment 232 can be drained.

[0065] According to some embodiments of the present utility model, the third pipe section 233 includes a vertical section 2331 and a docking section 2332, the vertical section 2331 extends in the up-down direction and the upper end of the vertical section 2331 is connected to the second pipe section 232, there is an angle between the docking section 2332 and the vertical section 2331, and the docking section 2332 has a docking joint 2333. That is, one end of the docking section 2332 is connected to one end of the vertical section 2331 away from the second pipe section 232, and the other end of the docking section 2332 has a docking joint 2333 to facilitate docking of the first device 10. Among them, the first device 10 is usually moved into the second device 20 in the horizontal direction to cooperate with the second device 20. Therefore, the docking section 2332 set at an angle with the vertical section 2331 is convenient for the first device 10 to move into the second device 20 in the horizontal direction and cooperate with the docking joint 2333 on the docking section 2332, that is, it is conducive to reducing the difficulty of docking the docking joint 2333 with the first device 10. In a specific example, the docking section 2332 and the vertical section 2331 are vertically arranged, which helps to further reduce the difficulty of docking the docking head 2333 with the first device 10.

[0066] According to some embodiments of the present invention, the functional component 24 is located below the second pipe segment 232 and between the supply box 22 and the third pipe segment 233. Thus, the functional component 24 can make full use of the space below the second pipe segment 232 and between the supply box 22 and the third pipe segment 233, thereby reducing the installation space occupied by the functional component 24 and the supply pipe 23 in the extension direction of the second pipe segment 232, with a compact structure and a reasonable layout.

[0067] According to some embodiments of the utility model, the functional component 24 includes a first connecting pipeline 243 and a second connecting pipeline 244, the first connecting pipeline 243 connects the first pump body 24 and the supply pipe 23, the second connecting pipeline 244 is connected to the first pump body 24, the first connecting pipeline 243 is connected to the upper side of the first pump body 24, and the second connecting pipeline 244 is connected to the lower side of the first pump body 24. That is, the first pump body 241 is connected to the supply pipe 23 through the first connecting pipeline 243, and in the up and down direction, the first pump body 241 is connected between the first connecting pipeline 243 and the second connecting pipeline 244. Therefore, in the residual liquid discharge mode, the first pump body 241 can inhale gas through the second connecting pipeline 244, and transport the gas to the supply pipe 23 through the first connecting pipeline 243 to discharge the cleaning liquid in the supply pipe 23. In addition, in the cleaning mode, the first pump body 241 is connected to the supply tank 22 through the first connecting pipe 243 and the supply pipe 23, so that under the drive of the first pump body 241, the liquid in the supply tank 22 can flow into the cleaning tank 25 of the second device 20 through the supply pipe 23 and the first connecting pipe 243, the first pump body 241 and the second connecting pipe 244, so that the mopping member 16 of the first device 10 can be cleaned by the cleaning liquid in the cleaning tank 25. In a specific example, the lower end of the second connecting pipe 244 is located directly above the cleaning tank 25 to ensure the reliability of conveying the cleaning liquid into the cleaning tank 25.

[0068] According to some embodiments of the utility model, the first device 10 includes a delivery pump 14, which is used to drive the cleaning liquid in the supply box 22 to be delivered to the storage box 13 through the supply pipe 23. In the residual liquid discharge mode, the delivery pump 14 does not work. That is, when the cleaning liquid in the supply pipe 23 is cleaned by the first pump body 241, the delivery pump 14 stops driving the cleaning liquid in the supply box 22 to be delivered to the storage box 13 through the supply pipe 23. As a result, it can be better to avoid that the gas delivered to the supply pipe 23 by the first pump body 241 due to the operation of the delivery pump 14 enters the storage box 13 through the supply pipe 23, thereby avoiding that the storage box 13 is in a negative pressure state, resulting in the cleaning liquid in the supply box 22 still being able to enter the storage box 13 through the supply pipe 23, that is, it can be better to avoid that the delivery pump 14 affects the first pump body 241 to discharge the residual liquid in the supply pipe 23, which is conducive to improving the discharge effect of the functional component 24 on the cleaning liquid in the supply pipe 23.

[0069] According to some embodiments of the utility model, the first device 10 includes a delivery pump 14, which is used to drive the cleaning liquid in the supply box 22 to be delivered to the storage box 13 through the supply pipe 23. In the residual liquid discharge mode, the delivery pump 14 works and the operating power of the delivery pump 14 is less than the operating power of the first pump body 241. Here, the operating power of the delivery pump 14 is less than the operating power of the first pump body 241, which means that the amount of cleaning liquid delivered by the delivery pump 14 per unit time is less than the amount of cleaning liquid that can be delivered by the first pump body 241 per unit time. Therefore, the delivery pump 14 can only pump part of the gas delivered to the supply pipe 23 by the first pump body 241 into the storage box 13, thereby driving the cleaning liquid in the supply pipe 23 between the gas input position of the first pump body 241 and the storage box 13 to flow into the storage box 13, and the remaining part of the gas delivered to the supply pipe 23 by the first pump body 241 can drive the cleaning liquid in the supply pipe 23 between the air input position of the first pump body 241 and the supply box 22 to flow into the supply box 22, so as to clean the residual liquid in the supply pipe 23.

[0070] According to some embodiments of the utility model, the second device 20 includes a cleaning component and a cleaning tank 25, and the cleaning component includes a second pump body 242, and the second pump body 242 is connected to the supply box 22, so as to transport the cleaning liquid in the supply box 22 to the cleaning tank 25. Therefore, the first device 10 can be cleaned by the cleaning liquid transported to the cleaning tank 25 by the second pump body 242. For example, after the first device 10 cooperates with the second device 20, the mopping and wiping member 16 of the first device 10 is located in the cleaning tank 25, so the cleaning liquid in the cleaning tank 25 can better remove the mud and dirt contaminated by the mopping and wiping member 16 in the process of cleaning the surface to be cleaned, so as to restore the cleanliness of the mopping and wiping member 16, which is conducive to improving the cleaning effect of the first device 10 on the surface to be cleaned.

[0071] According to some embodiments of the utility model, the first pump body 241 and the second pump body 242 are the same pump body, and the equipment assembly 100 has a cleaning mode, wherein in the cleaning mode, the first pump body 241 rotates forward, and the first pump body 241 rotates forward to transport the cleaning liquid in the supply box 22 to the cleaning tank 25, so as to clean the mopping member 16 in the cleaning tank 25 with the cleaning liquid in the cleaning tank 25; in the residual liquid discharge mode, the first pump body 241 rotates reversely, and the first pump body 241 rotates reversely to transport gas into the supply pipe 23 to clean the cleaning liquid in the supply pipe 23. Therefore, by integrating the functions of transporting the cleaning liquid into the cleaning tank 25 and transporting the gas into the supply pipe 23 into the first pump body 241, the integration of the first pump body 241 can be improved and the second pump body 242 can be saved, so that the number of parts of the second equipment 20 can be reduced, which is conducive to simplifying the structure of the second equipment 20 and reducing the production and manufacturing cost of the second equipment 20.

[0072] In a specific example, the first pump body 241 is a peristaltic pump, so that the first pump body 241 can realize the transportation of a variety of different media, such as liquid and gas, and at the same time can better ensure the accuracy and stability of the first pump body 241, and the operation noise is small.

[0073] According to some embodiments of the present invention, the first device 10 includes a storage box 13, a mop 16 and a delivery pump 14. The mop 16 is used to clean the surface to be cleaned. The delivery pump 14 is connected to the storage box 13 and is used to deliver external cleaning liquid to the storage box 13 and to deliver the cleaning liquid in the storage box 13 to the mop 16. That is, the storage box 13 is used to store the cleaning liquid. During the process of the first device 10 cleaning the surface to be cleaned, if the mop 16 is in contact with the surface to be cleaned and is movable relative to the surface to be cleaned so as to remove dirt on the surface to be cleaned by rubbing the surface to be cleaned with the mop 16, the delivery pump 14 can deliver the cleaning liquid in the storage box 13 to the mop 16 to wet the mop 16. The mop 16 soaked with the cleaning liquid can more effectively remove dirt on the surface to be cleaned, thereby improving the cleaning effect and cleaning efficiency of the first device 10 on the surface to be cleaned. When the cleaning liquid in the storage box 13 is exhausted, the first device 10 can be moved to the liquid replenishment location, which refers to the storage location of the external cleaning liquid. The storage box 13 is connected to the storage location of the external cleaning liquid, and the external cleaning liquid is transported to the storage box 13 through the delivery pump 14, so as to ensure that the cleaning liquid in the storage box 13 can be continuously transported to the mopping member 16 to clean the surface to be cleaned. In this way, the integration of the delivery pump 14 can be improved to reduce the number of delivery pumps 14, that is, the number of parts of the first device 10 can be reduced, which is conducive to simplifying the structure of the first device 10 and reducing the production cost of the first device 10. At the same time, it is convenient to reduce the overall size of the first device 10 to improve the throughput of the first device 10, which is conducive to broadening the application scenarios of the first device 10.

[0074] The cleaning liquid may be water, a cleaning agent such as a floor cleaning agent for cleaning the surface to be cleaned, or a mixed liquid of a cleaning agent and water, etc., and the type of the cleaning liquid is not specifically limited. In addition, the external cleaning liquid may be stored in a second device 20 that is detachably matched with the first device 10, and the first device 10 may replenish the cleaning liquid by returning to the second device 20. The external cleaning liquid may also come directly from a tap, etc., and is not specifically limited here.

[0075] In a specific example, the delivery pump 14 is a diaphragm pump, so that the delivery pump 14 can realize the delivery of a variety of different media, such as liquids and gases, and has good sealing performance to prevent leakage of the delivered media.

[0076] According to some embodiments of the utility model, the first device 10 has a replenishing mode and a cleaning mode. In the replenishing mode, the delivery pump 14 delivers the external cleaning liquid to the storage tank 13 and stops delivering the cleaning liquid to the mopping member 16. In the cleaning mode, the delivery pump 14 delivers the cleaning liquid in the storage tank 13 to the mopping member 16 and stops delivering the external cleaning liquid to the storage tank 13. Thus, the first device 10 can replenish the cleaning liquid in the storage tank 13 in the replenishing mode, and at the same time, it can avoid the waste caused by the delivery of the cleaning liquid to the mopping member 16. After the storage tank 13 is replenished, the first device 10 can continue to clean the surface to be cleaned. In the cleaning mode, the cleaning liquid is delivered to the mopping member 16 by the delivery pump 14, so that the mopping member 16 soaked with the cleaning liquid can more effectively remove the dirt on the surface to be cleaned, so as to better ensure the cleaning effect and cleaning efficiency of the surface to be cleaned by the first device 10 in the cleaning mode.

[0077] According to some embodiments of the present invention, the first device 10 includes: a first pipeline assembly and a second pipeline assembly, the first pipeline assembly is connected to both the storage box 13 and the delivery pump 14, and is used to deliver the external cleaning liquid to the storage box 13, and the second pipeline assembly is connected to both the storage box 13 and the delivery pump 14, and is used to deliver the cleaning liquid in the storage box 13 to the mopping member 16. That is, the first pipeline assembly can form a communicating liquid channel between the external cleaning liquid storage area and the storage box 13, and under the drive of the delivery pump 14, the external cleaning liquid can enter the storage box 13 through the part of the first pipeline assembly forming the communicating liquid channel to replenish the storage box 13 with the cleaning liquid; the second pipeline assembly can form a communicating liquid channel between the storage box 13 and the installation area of ​​the mopping member 16, and under the drive of the delivery pump 14, the cleaning liquid in the storage box 13 can be delivered to the mopping member 16 through the part of the second pipeline assembly forming the communicating liquid channel to wet the mopping member 16.

[0078] Therefore, the cleaning liquid can be added to the storage box 13 through the cooperation of the delivery pump 14 and the first pipeline assembly, and the cleaning liquid can be delivered to the mopping member 16 through the cooperation of the delivery pump 14 and the second pipeline assembly. That is, the needs of replenishing the cleaning liquid and wetting the mopping member 16 with the cleaning liquid can be met through the cooperation of the delivery pump 14 and the first pipeline assembly and the second pipeline assembly, which can better improve the integration of the delivery pump 14 and reduce the number of delivery pumps 14.

[0079] The second pipeline assembly includes a pumping pipeline 151 and a discharging pipeline 152. One end of the pumping pipeline 151 is connected to the storage box 13 and the other end is connected to the inlet of the delivery pump 14. The discharging pipeline 152 is connected to the outlet of the delivery pump 14. That is, the two ends of the pumping pipeline 151 are respectively connected to the inlet of the storage box 13 and the delivery pump 14, so that a communicating liquid channel can be formed between the storage box 13 and the inlet of the delivery pump 14 through the pumping pipeline 151. The delivery pump 14 is connected between the pumping pipeline 151 and the discharging pipeline 152. Therefore, under the drive of the delivery pump 14, the liquid in the storage box 13 can be sequentially delivered to the mopping member 16 through the pumping pipeline 151, the delivery pump 14 and the discharging pipeline 152, so as to realize the operation of delivering the cleaning liquid to the mopping member 16.

[0080] According to some embodiments of the present invention, the exhaust pipeline 113 and the discharge pipeline 152 are the same pipeline. That is, only one exhaust pipeline 113 or one discharge pipeline 152 is required, and the gas delivered by the delivery pump 14 can be discharged and the cleaning liquid delivered by the delivery pump 14 can be delivered to the wiping member 16 through the exhaust pipeline 113 or the discharge pipeline 152. In this way, the pipeline cost can be well saved, and the installation space occupied by the exhaust pipeline 113 or the discharge pipeline 152 can be saved.

[0081] According to some embodiments of the utility model, a second control valve is provided on the exhaust pipeline 113, and the second control valve is used to control the conduction and cutoff of the exhaust pipeline 113. That is, the second control valve can control the conduction of the exhaust pipeline 113, so that when the delivery pump 14 draws negative pressure to the storage box 13 through the exhaust pipeline 112, the gas extracted from the liquid storage chamber can be discharged through the exhaust pipeline 113; the second control valve can control the cutoff of the exhaust pipeline 113, so that when the delivery pump 14 draws the cleaning liquid in the storage box 13 through the extraction pipeline 151, the cleaning liquid drawn by the delivery pump 14 can only be delivered to the mopping and wiping member 16 through the discharge pipeline 152, so as to avoid the cleaning liquid flowing out through the exhaust pipeline 113 and affecting the wetting effect on the mopping and wiping member 16.

[0082] Among them, the connection position between the air extraction pipeline 112 and the storage box 13 is the first connection position, and the connection position between the material extraction pipeline 151 and the storage box 13 is the second connection position, and the first connection position is higher than the second connection position. That is to say, the position where the gas in the storage box 13 is discharged from the storage box 13 through the air extraction pipeline 112 is higher than the position where the cleaning liquid in the storage box 13 is discharged from the storage box 13 through the material extraction pipeline 151. Therefore, the position where the gas in the storage box 13 is discharged from the storage box 13 through the air extraction pipeline 112, that is, the first connection position, is set at a relatively high position, which can avoid the cleaning liquid in the storage box 13 being extracted during the process of pumping negative pressure into the storage box 13. In addition, the position where the cleaning liquid in the storage box 13 is discharged from the storage box 13 through the material extraction pipeline 151, that is, the second connection position, is set at a relatively low position, which can better ensure that the cleaning liquid in the storage box 13 can be drained and drained, so as to avoid the cleaning liquid remaining in the storage box 13 to cause waste or dirt.

[0083] In a specific example, one end of the discharge pipe 152 is connected to the outlet of the delivery pump 14 , and the other end of the discharge pipe 152 is located above the mopping member 16 and is open downward, so that the cleaning liquid can be sprayed downward from above the mopping member 16 to the mopping member 16 through the discharge pipe 152 .

[0084] According to some embodiments of the utility model, the first connection position is located at the upper end of the storage box 13, and the second connection position is located at the lower end of the storage box 13. Among them, the delivery pump 14 draws negative pressure to the storage box 13 through the air extraction pipeline 112 so that the external cleaning liquid can enter the storage box 13 under the action of the pressure difference. When the liquid level in the storage box 13 is higher than the first connection position, the cleaning liquid in the storage box 13 will be extracted through the air extraction pipeline 112, that is, the first connection position is the highest position where the delivery pump 14 cooperates with the first pipeline assembly to deliver the cleaning liquid into the storage box 13. Therefore, by setting the first connection position at the upper end of the storage box 13, the amount of cleaning liquid delivered to the storage box 13 by the delivery pump 14 and the first pipeline assembly can be increased, that is, the delivery pump 14 cooperates with the first pipeline assembly to make the external cleaning liquid roughly fill the storage box 13, thereby avoiding the waste of storage space in the storage box 13, and at the same time, it is beneficial to improve the endurance of the first device 10.

[0085] In addition, the second connection position is set at the lower end of the storage box 13, that is, the position where the cleaning liquid in the storage box 13 is discharged from the storage box 13 through the extraction pipeline 151 is located at the lower end of the storage box 13, so that the cleaning liquid in the storage box 13 can be drained and drained under the cooperation of the delivery pump 14 and the extraction pipeline 151 to avoid the cleaning liquid remaining in the storage box 13 to cause waste or dirt.

[0086] In a specific example, the first connection position is located at the top of the storage box 13. Therefore, when the liquid level in the storage box 13 has not reached the top of the storage box 13, the external cleaning liquid can continue to flow into the storage box 13 under the action of the negative pressure of the delivery pump 14 and the exhaust pipe 112 on the storage box 13 until the liquid level in the storage box 13 reaches the top of the storage box 13, thereby avoiding the waste of storage space in the storage box 13 and achieving high utilization rate.

[0087] According to some embodiments of the utility model, the connection position of the liquid inlet pipeline 111 and the storage box 13 is the third connection position, and the third connection position is lower than the first connection position. Among them, the connection position of the liquid inlet pipeline 111 and the storage box 13 is the position where the external cleaning liquid enters the storage box 13, that is, the position where the external cleaning liquid enters the storage box 13 through the liquid inlet pipeline 111 is lower than the position where the gas in the storage box 13 is discharged from the storage box 13 through the exhaust pipeline 112. In this way, it is possible to avoid the cleaning liquid in the storage box 13 being extracted during the process of pumping negative pressure into the storage box 13, and at the same time, it is possible to avoid wasting the storage space in the storage box 13.

[0088] In some embodiments, the first connection position and the third connection position are both higher than the highest liquid level in the storage tank 13. That is, when the cleaning liquid in the storage tank 13 reaches the highest liquid level, the position where the feed pipe 111 delivers the cleaning liquid into the storage tank 13 and the position where the delivery pump 14 sucks the air in the storage tank 13 are still located above the liquid surface. Thus, the delivery pump 14 can be prevented from pumping out the cleaning liquid in the storage tank 13, and the resistance of the feed pipe 111 delivering the cleaning liquid into the storage tank 13 can be reduced.

[0089] In some embodiments, the first connection position and the third connection position are both located at the top of the storage box 13. Thus, it can be ensured that the external cleaning liquid fills the storage box 13 under the action of the negative pressure drawn by the delivery pump 14. Since the connection position between the liquid inlet pipeline 111 and the storage box 13 is also located at the top of the storage box 13, the liquid inlet pipeline 111 does not need to overcome the resistance of the cleaning liquid in the storage box 13 when entering the storage box 13, that is, the resistance of the external cleaning liquid entering the storage box 13 through the liquid inlet pipeline 111 can be reduced, which is conducive to reducing the energy consumption of the delivery pump 14 in delivering the external cleaning liquid to the storage box 13.

[0090] According to some embodiments of the present invention, the connection position between the liquid inlet pipeline 111 and the storage box 13 is a third connection position, the third connection position is higher than the second connection position, and the third connection position is located at the upper part of the storage box 13. In other words, the position where the external cleaning liquid enters the storage box 13 through the liquid inlet pipeline 111 is higher than the position where the cleaning liquid in the storage box 13 is discharged from the storage box 13 through the extraction pipeline 151. Therefore, by setting the position where the external cleaning liquid enters the storage tank 13 through the liquid inlet pipe 111 at a relatively high position, it can be avoided that the cleaning liquid in the storage tank 13 hinders the external cleaning liquid from entering the storage tank 13 through the liquid inlet pipe 111, thereby reducing the resistance of the external cleaning liquid entering the storage tank 13 through the liquid inlet pipe 111, which is beneficial to reducing the energy consumption of the delivery pump 14 in delivering the external cleaning liquid to the storage tank 13; by setting the position where the cleaning liquid in the storage tank 13 is discharged from the storage tank 13 through the extraction pipe 151, that is, the second connection position, at a relatively low position, it can be better ensured that the cleaning liquid in the storage tank 13 can be drained, so as to avoid the cleaning liquid remaining in the storage tank 13 to cause waste or dirt.

[0091] According to some embodiments of the utility model, the connection position between the liquid inlet pipeline 111 and the storage box 13 is the third connection position, and the third connection position and the first connection position are located on the same side of the storage box 13. That is to say, the position where the gas in the storage box 13 is discharged from the storage box 13 through the air extraction pipeline 112 and the position where the external cleaning liquid enters the storage box 13 through the liquid inlet pipeline 111 are located on the same side of the storage box 13. As a result, the interval between the position where the gas in the storage box 13 is discharged from the storage box 13 through the air extraction pipeline 112 and the position where the external cleaning liquid enters the storage box 13 through the liquid inlet pipeline 111 can be shortened, that is, the position where the negative pressure is pumped to the storage box 13 is close to the position where the external cleaning liquid enters the storage box 13, so that the negative pressure value at the place where the external cleaning liquid enters the storage box 13 can be increased, and then the pressure difference between the storage position of the external cleaning liquid and the third position can be increased, which is conducive to improving the efficiency of the external cleaning liquid entering the storage box 13.

[0092] According to some embodiments of the present invention, the spacing range L between the first connection position and the third connection position satisfies: 0<L≤100mm. That is, the spacing between the position where the gas in the storage box 13 is discharged from the storage box 13 through the exhaust pipe 112 and the position where the external cleaning liquid enters the storage box 13 through the liquid inlet pipe 111 is controlled within the range of 0 (excluding 0) to 100mm (including 100mm). For example, the spacing between the position where the gas in the storage box 13 is discharged from the storage box 13 through the exhaust pipe 112 and the position where the external cleaning liquid enters the storage box 13 through the liquid inlet pipe 111 can be: 5mm, 8mm, 10mm, 20mm, 30mm, 40mm, 60mm, 80mm, 100mm, etc., and no specific restrictions are made here. In this way, it can be avoided that the distance between the first connection position and the third connection position is too small, resulting in the external cleaning liquid entering the storage box 13 through the liquid inlet pipe 111 and then being directly sucked away by the exhaust pipe 112. At the same time, it can be avoided that the distance between the first connection position and the third connection position is too large to affect the negative pressure extraction effect of the exhaust pipe 112 on the third connection position. Therefore, it is possible to ensure the negative pressure value of the external cleaning liquid entering the storage box 13 while avoiding the cleaning liquid entering the storage box 13 through the liquid inlet pipe 111 from being sucked into the exhaust pipe 112, and the layout is reasonable.

[0093] According to some embodiments of the utility model, the first pipeline assembly includes a first pipeline and a second pipeline, one end of the first pipeline is connected to the inlet of the delivery pump 14 and the other end is formed as a docking port 1111, wherein the docking port 1111 is used to dock with an external storage location of the cleaning liquid, one end of the second pipeline is connected to the outlet of the delivery pump 14 and the other end is connected to the storage tank 13, a third control valve is provided on the first pipeline, the third control valve is used to control the conduction and cutoff of the first pipeline, a fourth control valve is provided on the second pipeline, the fourth control valve is used to control the conduction and cutoff of the second pipeline, the second pipeline assembly includes a third pipeline and a fourth pipeline, one end of the third pipeline is connected to the inlet of the delivery pump 14 and the other end is connected to the storage tank 13, the fourth pipeline is connected to the outlet of the delivery pump 14, a fifth control valve is provided on the third pipeline, the fifth control valve is used to control the conduction and cutoff of the third pipeline, a sixth control valve is provided on the fourth pipeline, the sixth control valve is used to control the conduction and cutoff of the fourth pipeline.

[0094] That is, the delivery pump 14 can be connected to the external cleaning liquid storage location through the first pipeline, the delivery pump 14 can be connected to the storage box 13 through the second pipeline and the third pipeline, and the delivery pump 14 can also deliver the cleaning liquid to the mopping and wiping member 16 through the fourth pipeline. Among them, the first pipeline, the second pipeline, the third pipeline and the fourth pipeline can be independently controlled to be connected or cut off, so that by controlling the connection or cutoff of the first pipeline, the second pipeline, the third pipeline and the fourth pipeline respectively, a single delivery pump 14 can be used to deliver the external cleaning liquid to the storage box 13 and the cleaning liquid in the storage box 13 to the mopping and wiping member 16, which is conducive to simplifying the structure of the first device 10.

[0095] Specifically, when it is necessary to replenish the storage box 13, after the docking port 1111 is connected to the storage position of the external cleaning liquid, the third control valve is controlled to connect the first pipeline, the fourth control valve is controlled to connect the second pipeline, the third pipeline is cut off by the fifth control valve, and the fourth pipeline is cut off by the sixth control valve, so that under the drive of the delivery pump 14, the external cleaning liquid can only be delivered to the storage box 13 through the first pipeline, the delivery pump 14, and the second pipeline in sequence; when it is necessary to deliver the cleaning liquid in the storage box 13 to the mopping member 16, the third control valve is controlled to cut off the first pipeline, the fourth control valve is controlled to cut off the second pipeline, the third pipeline is connected by the fifth control valve, and the fourth pipeline is connected by the sixth control valve, so that under the drive of the delivery pump 14, the cleaning liquid in the storage box 13 can only be delivered to the mopping member 16 through the third pipeline, the delivery pump 14, and the fourth pipeline in sequence.

The supply pipe 23 includes a first pipe section 231, a second pipe section 232 and a third pipe section 233. The first pipe section 231 extends in the up-down direction, the second pipe section 232 extends in the horizontal direction, and the third pipe section 233 includes a vertical section 2331 extending in the up-down direction and a docking section 2332 extending in the horizontal direction.

The functional component 24 includes a first pump body 241, a second pump body 242, a first connecting pipeline 243 and a second connecting pipeline 244. The first pump body 241 and the second pump body 242 are the same pump body and the first pump body 241 can rotate forward and reverse to achieve driving of the fluid in two directions. The upper end of the first connecting pipeline 243 is connected to the middle position of the second pipe section 232, the first pump body 241 is connected to the lower end of the first connecting pipeline 243 and the upper end of the second connecting pipeline 244, and the lower end of the second connecting pipeline 244 is located directly above the cleaning tank 25.

[0099] Specifically, the equipment component 100 has a feeding mode, a residual liquid discharge mode, a cleaning mode and a cleaning mode.

[0100] In the feeding mode, the first device 10 returns to the second device 20 and cooperates with the second device 20. At this time, the docking head 2333 is connected to the docking port 1111, the supply pipe 23 is connected to the liquid inlet pipe 111, and the trigger member 21 attracts the valve core 121 to squeeze the elastic reset member 122 and move it to the conducting position. At this time, the air extraction pipe 112 is in a conducting state, and the first pump body 241 is controlled to be closed and the delivery pump 14 is controlled to be turned on. The delivery pump 14 discharges the gas in the storage box 13 through the air extraction pipe 112 and the exhaust pipe 113, and a negative pressure is formed in the storage box 13. The cleaning liquid in the supply box 22 enters the storage box 13 along the supply pipe 23 and the liquid inlet pipe 111 under the action of the pressure difference on both sides until the cleaning liquid in the storage box 13 reaches the preset liquid level.

[0101] In the residual liquid discharge mode, when the cleaning liquid in the storage tank 13 reaches a preset liquid level, the delivery pump 14 is controlled to close and the first pump body 241 is controlled to reverse, thereby delivering the gas to the second pipe section 232 through the second connecting pipe 244 and the first connecting pipe 243. The gas entering the second pipe section 232 is divided into two streams flowing toward the supply tank 22 and the storage tank 13, thereby pushing the liquid in the supply pipe 23 to flow into the supply tank 22 and the storage tank 13 until the residual liquid in the supply pipe 23 is drained.

[0102] In the cleaning mode, the delivery pump 14 is controlled to be closed and the first pump body 241 is controlled to rotate forward. The first pump body 241 drives the cleaning liquid in the supply box 22 to be delivered to the cleaning tank 25 through the supply pipe 23 located between the supply box 22 and the first connecting pipe 243, the first connecting pipe 243 and the second connecting pipe 244, so as to clean the mopping member 16 located in the cleaning tank 25 with the cleaning liquid in the cleaning tank 25.
