Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of cleaning equipment, in particular to a cleaning base station, a cleaning equipment and a cleaning system. BACKGROUND

[0002] In order to realize the functional diversity of the cleaning equipment such as the mop and the scrubber and meet the individual needs of users, some existing cleaning equipment and base stations have the ability to add different additives. Taking the additive as a maintenance liquid for example, at present, the ground maintenance function of the cleaning equipment on the market mainly has the following two schemes:

[0003] Firstly, the maintenance is performed by manually spraying essential oil type maintenance liquid. Although this method can deeply maintain the floor, the brightening effect is not obvious and the durability of the maintenance effect is poor.

[0004] Secondly, the maintenance is performed by manually or mechanically applying wax emulsion type maintenance liquid. Since the wax content of the maintenance liquid applied to the cleaning part or the ground is low and the water content is high, the maintenance liquid is not easy to evaporate and condense, the durability of the maintenance effect is good, and the brightening effect is also relatively obvious. Considering the space factor, in order to ensure the maintenance frequency, that is, to ensure the endurance of the maintenance, the maintenance liquid is usually concentrated to different degrees in practical applications to be stored in the liquid storage device. When maintenance is needed, the concentrated maintenance liquid is output from the liquid storage device through the pipeline and used by being mixed with water. However, since the water content of the concentrated wax emulsion type maintenance liquid is low, once the pipeline for conveying the maintenance liquid is exposed to the air during or after use, the water in the concentrated maintenance liquid in the pipeline will evaporate and condense, which will easily cause the pipeline to be blocked.

[0005] Not only the maintenance liquid, but also other additives may cause the pipeline to be blocked and corroded due to long-term residence in the base station or the cleaning equipment pipeline, thereby causing the pipeline to fail to function. In particular, since the cleaning base station integrates various functions and is usually arranged in the user's home, its volume should not be too large. Similarly, since the cleaning equipment has many functional components, in order to facilitate obstacle crossing and cleaning in a small space, its volume should also not be too large. Therefore, the waterway system in the base station and / or the cleaning equipment in the cleaning system generally occupies a small space, and accordingly, the pipeline diameter of the waterway system used is small. Therefore, the condensation problem of the liquid pipeline in the cleaning system is particularly serious.

[0006] Therefore, it is urgent to solve the problem that the additive conveying pipeline is easily blocked due to additive condensation or the pipeline is damaged due to additive corrosion. INVENTION CONTENTS

[0129] The above maintenance types are only exemplary descriptions and are not limiting to the present disclosure.

[0130] The cleaning base station 100 provided by the embodiments of the present disclosure is described in detail below.

[0131] As Figure 1 or Figure 5As shown, the cleaning base station 100 comprises a base station body 110 and an additive liquid path system 300, which is arranged on the base station body 110. The base station body 110 is provided with a parking position for the cleaning equipment 200 to park. It should be noted that the additive described herein includes but is not limited to 84 disinfectant, alcohol, essential oil, dew, essential oil maintenance liquid, wax milk maintenance liquid and various functional liquids. For the convenience of description, the following will take the additive as the wax milk maintenance liquid as an example for description.

[0132] In addition, the additive liquid path system 300 can be installed in a modular manner. Users can choose whether to install the additive liquid path system 300 and use the additive adding function according to actual needs. Of course, the additive liquid path system 300 can also adopt other existing or newly created suitable installation methods, which are not particularly limited here.

[0133] In embodiments of the present disclosure, as shown in Figure 1 and Figure 2 , or Figure 5 and Figure 6 , the additive liquid path system 300 comprises a first liquid supply link 1, a second liquid supply link 2 and a control unit 6, wherein the first liquid supply link 1 can be used to transport clean water, the second liquid supply link 2 includes but is not limited to transporting additives, and the control unit 6 includes but is not limited to controlling the additive liquid path system 300 to transport target additives and controlling the pipeline of the additive liquid path system 300 to be cleaned by clean water.

[0134] Exemplarily, as shown in Figure 1 and Figure 2 , or Figure 5 and Figure 6 , the first liquid supply link 1 has an input end 11 and an output end 12, wherein the input end 11 is connected to the clean water source 4, and the output end 12 is used to output clean water. The clean water source 4 described herein includes but is not limited to a clean water tank, a water pipeline, clean water in a cleaning tank 120 of the cleaning base station 100, etc., which are not particularly limited here, as long as the clean water source 4 can provide clean water for the first liquid supply link 1. It should be noted that the cleaning tank 120 of the cleaning base station 100 is used for the cleaning equipment 200 to park in the cleaning base station 100, and the cleaning part of the cleaning equipment 200 is located at the cleaning tank 120, so that the sewage generated by cleaning the cleaning part of the cleaning equipment 200 can be discharged to the cleaning tank 120.

[0135] In embodiments of the present disclosure, as shown in Figure 1 and Figure 2 , or Figure 5 and Figure 6As shown in the figure, the second liquid supply link 2 comprises an additive delivery pipeline 21, which is mainly used for delivering additives, such as delivering concentrated wax emulsion maintenance liquid, so as to be mixed with the clean water delivered by the first liquid supply link 1 into the target maintenance liquid, and then delivered and sprayed onto the cleaning element such as the mop of the cleaning device 200, or into the cleaning tank 120 of the cleaning base station 100, etc.

[0136] For example Figure 1 and Figure 2 , or Figure 5 and Figure 6 As shown in the figure, the second liquid supply link 2 is also provided with an additive module 5, which is mainly used for containing additives. In order to realize that the second liquid supply link 2 not only has the function of delivering additives, but also has the function of self-cleaning, the additive module 5 has a first communication port 51 and a second communication port 52 which are in communication with each other, wherein the second communication port 52 and the output end 12 of the first liquid supply link 1 are communicated through the additive delivery pipeline 21.

[0137] It should be noted that the first communication port 51 can be used for inputting or outputting clean water, and the second communication port 52 can be used for outputting additives, and can also be used for inputting or outputting clean water, which can be determined according to the specific structure of the additive liquid system 300 and actual needs.

[0138] It should be further noted that the additive module 5 can be installed in the dust collection bin of the cleaning base station 100, or can be installed at other suitable positions of the cleaning base station 100.

[0139] For example Figure 1 and Figure 2 , or Figure 5 and Figure 6 As shown in the figure, the control unit 6 is connected to the second liquid supply link 2, and the control unit 6 has a first state and a second state. Wherein, when the control unit 6 is in the first state, the control unit 6 controls the additives in the additive module 5 to be delivered from the second communication port 52 to the output end 12 of the first liquid supply link 1 through the additive delivery pipeline 21, so that the additives output by the additive delivery pipeline 21 can be mixed with the clean water delivered by the first liquid supply link 1, so as to finally form the target additive for actual use. The user does not need to ask a professional agency to add maintenance liquid or other target additives, nor does the user need to add maintenance liquid or other target additives with both hands, that is, it is beneficial to realize the automatic addition of maintenance liquid or other target additives, so as to realize the automatic maintenance of the cleaning surface such as the ground and other additional functions.

[0140] It should be noted that in the case of additives being maintenance liquid, the additive delivery pipeline 21 is prone to condensation in the normal use process of the user due to the small pipeline and the high concentration of the delivered additives. In the case of additives being high-concentration disinfectant liquid, the additive delivery pipeline 21 is prone to corrosion by the additives.

[0141] In the second state of the control unit 6, the control unit 6 controls the clean water from the clean water source 4 to enter the second liquid supply link 2 to at least clean the additive delivery pipeline 21 by the clean water, so that at least part of the additive remaining in the additive delivery pipeline 21 after the first state is discharged, so as to realize the self-cleaning function of the additive delivery pipeline 21 after the delivery of the additive, reduce the probability of pipeline blockage, corrosion and other problems caused by the long-term residence of the additive in the pipeline of the cleaning base station 100, and further ensure the liquid flow delivery function of the pipeline, improve the use reliability of the cleaning base station 100, and improve the user's use experience.

[0142] Understandably, the first state described herein is mainly the state of the additive liquid system 300 when delivering the additive, and the second state is mainly the state of the additive delivery pipeline 21 of the second liquid supply link 2 of the additive liquid system 300 when self-cleaning, wherein the user can select the control unit 6 to be in the first state or the second state according to actual needs, or the control unit 6 controls its own state according to the current task process of the cleaning equipment 200. For example, after the cleaning equipment 200 cleans the surface to be cleaned, and receives the instruction to maintain the surface to be cleaned, the control unit 6 is started and in the first state, and the second liquid supply link outputs the additive (such as maintenance liquid). After the cleaning equipment 200 completes the maintenance task this time, and the cleaning equipment 200 returns to the cleaning base station 100, the control unit 6 is started and in the second state, and the additive delivery pipeline is cleaned.

[0143] In summary, compared with the prior art, the cleaning base station 100 at least has the following beneficial effects:

[0144] The cleaning base station 100 sets the additive liquid system 300 including the first liquid supply link 1, the second liquid supply link 2, and the control unit 6, wherein the second liquid supply link 2 includes the additive delivery pipeline and is further provided with the additive module 5 having the first communication port 51 and the second communication port 52. When the user needs to use the target additive to achieve the maintenance of the surface to be cleaned and other additional functions, the control unit 6 can control the additive in the additive module 5 to be delivered to the output end 12 of the first liquid supply link 1 through the additive delivery pipeline 21 from the second communication port 52, so as to be mixed with the clean water delivered by the first liquid supply link 1 to obtain the target additive such as maintenance liquid. Without the need for professional agencies or the user to manually add the target additive such as maintenance liquid. After adding the target additive, the control unit 6 can also control the clean water of the clean water source 4 to enter the second liquid supply link 2, so as to at least automatically clean the additive delivery pipeline 21 by the clean water, thereby reducing the probability of pipeline blockage, corrosion and other problems caused by the long-term residence of the additive in the pipeline of the cleaning base station 100, so as to ensure the liquid flow delivery function of the pipeline, improve the use reliability of the cleaning base station 100, and improve the user's use experience.

[0145] The inventor further found through creative labor that long-term retention of the above-mentioned additive in the additive delivery pipeline 21 can cause pipeline blockage, corrosion and other problems, thereby causing the waterway function to fail. When the cleaning base station 100 is equipped with a manual water-adding clean water tank, by taking the clean water tank of the cleaning base station 100 as the clean water source 4, the additive delivery pipeline 21 can be cleaned when the water in the clean water tank is sufficient, but the user may forget to add clean water to the clean water tank due to various reasons, so that the additive delivery pipeline 21 cannot be cleaned, thereby causing the additive delivery pipeline 21 to be not cleaned in time, causing part of the pipeline in the cleaning base station 100 to be damaged or blocked. Alternatively, the cleaning base station 100 is connected to a tap water pipe, and the clean water source is a municipal water source, but when the user's home is in a water outage situation, the additive delivery pipeline 21 cannot be cleaned, thereby also causing part of the pipeline in the cleaning base station 100 to be damaged or blocked.

[0146] To solve the above-mentioned specific technical problems, the embodiments of the present disclosure are further improved based on the above-mentioned embodiments to improve the reliability of cleaning the additive delivery pipeline.

[0147] In some embodiments of the present disclosure, as shown in Figure 1 The first liquid supply link 1 is provided with a standby container 13 and a first driving member 14. The standby container 13 is arranged in the first liquid supply link 1 and is used to contain standby clean water and supply clean water to flow. The standby container 13 is connected between the clean water source 4 and the output end 12 of the first liquid supply link 1. In this embodiment, by adding the standby container 13, at least the additive delivery pipeline 21 of the second liquid supply link 2 can still be cleaned when there is no water in the clean water source 4, reducing the damage of the additive in the pipeline to the pipeline due to the long-term lack of water in the clean water source 4, such as blockage, corrosion and the like, thereby improving the service life and stability of the cleaning base station 100. The first driving member 14 is used to drive the clean water to be delivered to the output end 12 of the first liquid supply link 1 through the first liquid supply link 1.

[0148] For example, to realize the function of the standby container 13 containing standby clean water, in a specific embodiment, to improve the water pumping and draining efficiency and ensure the lowest cost, the standby container 13 can be a flexible bag body. For example, the flexible bag body includes a bag body (not shown), a water inlet connector (not shown), and a water outlet connector (not shown). The bag body can be made of a composite film material of PE and nylon. The water inlet connector and the water outlet connector are respectively connected to the first liquid supply link 1 along the water outlet direction of the first liquid supply link 1. Since the standby container 13 is a flexible bag body, the flexible bag body can be deformed to balance the air pressure inside and outside the standby container 13.

[0149] Alternatively, in another specific embodiment, the spare container 13 may be a box body with a vent (not shown) for communicating the interior of the spare container 13 with the atmosphere. A one-way valve (not shown) is provided at the vent, which allows air to enter the spare container 13 from the outside and prevents air from entering the atmosphere from the vent, so as to ensure that the air pressure inside and outside the box is kept balanced and to reduce the probability of the box body being sucked and deformed.

[0150] For example Figure 2 As shown, the first driving component 14 is connected between the clean water source 4 and the output end 12 of the first liquid supply link 1. When the clean water source 4 has water and the control unit 6 is in the first state, the first driving component 14 is used to draw clean water from the clean water source 4 so that the clean water is transported through the first liquid supply link 1 to the output end 12 of the first liquid supply link 1 for mixing with the additive transported by the additive transport pipeline 21.

[0151] In some embodiments, when there is water in the clean water source 4 and the control unit 6 is in the second state, the first driving member 14 is at least used to drive the clean water in the spare container 13 to be transported to the additive delivery pipeline 21 to clean the additive delivery pipeline 21, thereby reducing the probability of the additive in the additive delivery pipeline 21 being blocked or corroded due to the additive remaining in the pipeline of the cleaning base station 100 for a long time, ensuring the normal liquid delivery function of the liquid pipeline, and improving the user experience.

[0152] When the clean water source 4 is dry and the control unit 6 is in the first state, the first driving component 14 can be used to drive the clean water in the spare container 13 to be transported through the first liquid supply link 1 to the output end 12 of the first liquid supply link 1, so as to mix with the additive transported by the additive transport pipeline 21.

[0153] In some embodiments, when the water source 4 is empty and the control unit 6 is in the second state, the first driving member 14 is configured to drive the clean water in the backup container 13 to at least the additive delivery pipeline 21 to clean the additive delivery pipeline 21, thereby reducing the probability of pipeline blockage, corrosion and other problems caused by long-term residence of additives in the pipeline of the cleaning base station 100, ensuring the normal liquid delivery function of the liquid pipeline, and improving the user experience. In some embodiments, when the backup container 13 is a flexible bag, the first driving member 14 can be arranged between the water source 4 and the backup container 13, that is, the first driving member 14 is arranged upstream of the backup container 13. When the water source 4 has water, whether the control unit 6 is in the first state or the second state, when the first driving member 14 pumps the clean water from the water source 4, it can ensure that the backup container 13 is first filled with clean water as backup clean water, and then the clean water is delivered downstream of the backup container 13. If the backup container 13 is arranged upstream of the first driving member 14, the first driving member 14 will first suck the air in the backup container 13 (flexible bag), which will cause the backup container 13 (flexible bag) to be sucked flat, and thus the clean water from the water source 4 will be difficult to enter the backup container 13. Therefore, when the backup container 13 is a flexible bag, arranging the first driving member 14 upstream of the backup container 13 can effectively prevent the backup container 13 from being first pumped by the first driving member 14. The internal air, causing the clean water from the water source 4 to be difficult to enter the backup container 13. After the backup container 13 is filled with clean water, the backup container 13 can be equivalent to a passage for clean water, that is, at this time, when the control unit 6 is in the first state, the clean water pumped from the water source 4 by the first driving member 14 can be delivered to the output end 12 of the first liquid supply link 1 through the backup container 13. When the control unit 6 is in the second state, the clean water pumped from the water source 4 by the first driving member 14 can be delivered to the additive delivery pipeline 21 of the second liquid supply link 2 through the backup container 13.

[0154] In other embodiments, when the backup container 13 is a box, the box is provided with an air vent (not shown) for communicating the inside of the backup container 13 with the atmosphere, and a one-way valve is arranged at the air vent to allow air to enter the backup container 13 from the outside of the backup container 13 and prevent air in the backup container 13 from entering the atmosphere through the air vent. Since the air pressure inside and outside the box is balanced through the air vent and the one-way valve, the problem of the box being sucked flat can be basically avoided. In this embodiment, the relative position relationship between the first driving member 14 and the backup container 13 can not be particularly limited, for example, the first driving member 14 can be arranged upstream of the backup container 13, or it can also be arranged downstream of the backup container 13.

[0155] When the first driving member 14 is arranged upstream of the standby container 13, in the case that the clean water source 4 is out of water and the control unit 6 is in the first state, the first driving member 14 is used to suck air at the clean water source 4 to apply positive pressure to the standby container 13 to squeeze clean water in the standby container 13, so that the clean water is delivered to the output end 12 of the first liquid supply link 1. In the case that the clean water source 4 is out of water and the control unit 6 is in the second state, the first driving member 14 is used to suck air at the clean water source 4 to apply positive pressure to the standby container 13 to squeeze clean water in the standby container 13, so that the clean water is delivered to at least the additive delivery pipeline 21.

[0156] When the first driving member 14 is arranged downstream of the standby container 13, in the case that the clean water source 4 is out of water and the control unit 6 is in the first state, the first driving member 14 is used to suck clean water in the standby container 13, so that the clean water is delivered to the output end 12 of the first liquid supply link 1. In the case that the clean water source 4 is out of water and the control unit 6 is in the second state, the first driving member 14 is used to suck clean water in the standby container 13, so that the clean water is delivered to at least the additive delivery pipeline 21.

[0157] Exemplarily, the cleaning base station 100 of the embodiments of the present disclosure can also be reversely powered by the cleaning device 200, for example, the bidirectional flow control of current can be realized by back-to-back mos tubes. In normal cases, the cleaning base station 100 is connected to a household power supply, and when the cleaning device 200 is docked at the cleaning base station 100, the cleaning base station 100 can power the cleaning device 200, and when the cleaning base station 100 is powered off, the cleaning device 200 can also reversely power the cleaning base station 100. In this way, even in the case that the cleaning base station 100 is powered off, the control unit 6 and the first driving member 14 of the cleaning base station 100 can be normally powered by the cleaning device 200, thereby not affecting the functions of the output additive and flushing additive delivery pipelines.

[0158] In some embodiments of the present disclosure, as shown in Figure 5 To simplify the liquid path structure of the additive liquid path system 300 and the smoothness and orderliness of the liquid flow, the additive liquid path system 300 further comprises a multi-way joint 7. The multi-way joint 7 is provided with at least a first interface 71, a second interface 72 and a third interface 73, wherein the first interface 71 (see Figure 6 or Figure 1 to Figure 6 ) is connected with the output end 12 of the first liquid supply link 1, the second interface 72 (see Figure 1 to Figure 6 or Figure 3 to Figure 6 ) is connected with the additive delivery pipeline 21 to communicate the second communication port 52 with the output end 12 of the first liquid supply link 1, and the third interface 73 (see Figure 3 or Figure 4The additive delivery pipeline 21 is connected to the total liquid outlet pipeline 3, and the total liquid outlet pipeline 3 is connected to the cleaning tank 120 of the cleaning base station 100 or the cleaning device 200. Understandably, the additive delivered by the additive delivery pipeline 21 and the clean water delivered by the first liquid supply link 1 can be mixed into the target additive directly in the total liquid outlet pipeline 3.

[0159] Similarly, the additive liquid path system 300 can also include a liquid collection container 8 (see Figure 3 ), wherein the liquid collection container 8 is used to collect the target additive output by the total liquid outlet pipeline 3, for example, the liquid collection container 8 can be the cleaning tank 120 of the cleaning base station 100, etc. In addition, the liquid collection container 8 can be connected to a sewage tank or a sewer or outside the cleaning base station 100.

[0160] In some embodiments of the present disclosure, as Figure 4 shown, the first driving member 14 is connected between the standby container 13 and the clean water source 4, and the first liquid supply link 1 is provided with a first one-way valve 15 located between the first driving member 14 and the standby container 13 to ensure one-way conduction of the first liquid supply link 1. The first one-way valve 15 is configured to be one-way conducted in the direction from the first driving member 14 to the standby container 13, so as to prevent the clean water in the standby container 13 from flowing back to the first driving member 14. That is, the first one-way valve 15 can be conducted in the direction from the first driving member 14 to the standby container 13, but cannot be conducted in the direction from the standby container 13 to the first driving member 14.

[0161] In addition, the first one-way valve 15 has a first preset pressure limit value, and when the fluid pressure between the clean water source 4 and the first one-way valve 15 is greater than the first preset pressure limit value, the first one-way valve 15 is opened to make the first liquid supply link 1 conductive. It should be noted that the fluid between the clean water source 4 and the first one-way valve 15 can be air flow or water flow.

[0162] For example, when the clean water source 4 has clean water, the pressure of the clean water extracted by the first driving member 14 into the first one-way valve 15 is usually greater than the first preset pressure limit value of the first one-way valve 15, so that the first one-way valve 15 can be conducted in the direction from the first driving member 14 to the standby container 13, thereby making the clean water enter the standby container 13. After the standby container 13 is filled with clean water, the clean water is delivered out of the standby container 13.

[0163] In addition, when the clean water source 4 is dry, after the control unit 6 has finished extracting the clean water from the backup container 13, the control unit 6 can delay its operation for a while to extract the air from the backup container 13. This prevents the backup container 13 from having too much air, which would make it difficult to supply water to the backup container 13 when the clean water source 4 becomes available later. This reduces the difficulty of filling the backup container 13 with clean water when the clean water source 4 becomes available later. In this embodiment, the first driving component 14 mainly provides power for transporting clean water. For the cleaning base station 100, the clean water can at least be used to clean the cleaning components of the cleaning equipment 200. Therefore, the required amount of clean water is usually large, and thus the flow rate of the first driving component 14 usually needs to be large. Based on this, the first driving component 14 in this embodiment can be a water pump or a water-air dual-purpose pump. Because of the inherent nature of water pumps or water-air dual-purpose pumps, they lack a shut-off function. Instead, a first one-way valve 15 is installed between the first drive unit 14 and the backup container 13. This first one-way valve 15 has a certain first preset pressure limit value, and it only opens when the externally applied unidirectional pressure exceeds this first preset value. Those skilled in the art can select a first one-way valve 15 with a larger opening pressure as needed. Thus, during the delayed operation of the control unit 6, the airflow pressure between the clean water source 4 and the first one-way valve 15 is usually less than the first preset pressure limit value of the first one-way valve 15, preventing the first one-way valve 15 from conducting in the direction from the first drive unit 14 to the backup container 13. This shut-off function of the first one-way valve 15 prevents air from entering the backup container 13 and affecting its effective volume.

[0164] In some embodiments of this disclosure, such as Figure 3 As shown, to ensure unidirectional flow of the main outlet line 3, a second check valve 31 is provided in the main outlet line 3. The second check valve 31 is configured to unidirectionally flow from the third interface 73 to the outlet of the main outlet line 3, so as to prevent liquid in the clean water box of the cleaning equipment 200 or the cleaning tank 120 of the cleaning base station 100 from flowing back towards the multi-way connector 7. In addition, the second check valve 31 has a second preset pressure limit value, which opens to allow the main outlet line 3 to flow when the fluid pressure between the third interface 73 and the second check valve 31 is greater than the second preset pressure limit value.

[0165] For example, when the clean water source 4 has clean water and the control unit 6 is in the first state, the clean water and additives delivered by the first liquid supply link 1 and the additives delivered by the additive delivery pipeline 21 can converge at the third interface 73 and deliver the target additive through the main liquid outlet pipeline 3. The pressure of the target additive between the third interface 73 and the second one-way valve 31 will be greater than the second preset pressure limit value of the second one-way valve 31, thereby realizing the delivery of the target additive.

[0166] In addition, when the clean water source 4 is empty and the control unit 6 is in the second state, the first driving member 14 can first work for a first preset time length, for example, the first driving member 14 can first briefly inflate the standby container 13, so that the standby clean water in the standby container 13 is discharged to the total liquid outlet pipeline 3 through the first liquid supply link 1. In this case, the pressure of the target additive between the third interface 73 of the multi-way joint 7 and the second one-way valve 31 is greater than the second preset pressure limit value of the second one-way valve 31, so that part of the standby clean water is discharged from the total liquid outlet pipeline 3, so as to ensure that the target additive remaining in the total liquid outlet pipeline 3 is also cleaned, thereby reducing the probability of damage such as blockage and corrosion of the total liquid outlet pipeline 3.

[0167] Subsequently, since the control unit 6 controls the second liquid supply link 2 to be turned on and provides driving power for the clean water to enter the second liquid supply link 2, and the third interface 73 to the second one-way valve 31 has a large resistance due to the presence of the second one-way valve 31, the pressure of the gas and / or clean water and / or other fluids between the third interface 73 of the multi-way joint 7 and the second one-way valve 31 is less than the second preset pressure limit value of the second one-way valve 31, so that most of the clean water or air cannot enter the total liquid outlet pipeline 3 through the third interface 73, and the second one-way valve 31 cannot be turned on in the direction from the third interface 73 to the outlet of the total liquid outlet pipeline 3. In this way, most of the clean water in the standby container 13 can enter the second liquid supply link 2 from the first liquid supply link 1, so as to clean the second liquid supply link 2.

[0168] In some embodiments of the present disclosure, in order to realize the functions of the control unit 6, the control unit 6 at least has the following two specific implementations, which are as follows:

[0169] In the first specific implementation of the control unit 6, as shown in Figure 4 the control unit 6 includes a second driving member 61, which is arranged in the additive delivery pipeline 21 and located between the second communication port 52 of the additive module 5 and the output end 12 of the first liquid supply link 1. In this first specific implementation, the first state is that the second driving member 61 is in a forward rotation state, and the second state is that the second driving member 61 is in a reverse rotation state. For example, the second driving member 61 can be a peristaltic pump, which generally has a small flow rate and has a self-locking function, i.e., in the state where the peristaltic pump is not turned on, fluid cannot pass through the peristaltic pump.

[0170] The second driving member 61 can be used to drive the additives in the additive module 5 to be transported from the second communication port 52 to the output end 12 of the first liquid supply link 1 through the additive delivery pipeline 21 in the forward rotation state, so as to control the automatic delivery of the additives. The second driving member 61 can also be used to drive the clean water to be transported from the output end 12 of the first liquid supply link 1 to the second liquid supply link 2 in the reverse rotation state, so as to control the cleaning of the second liquid supply link 2. Understandably, the automatic delivery of the additives and the cleaning of the second liquid supply link 2 by the clean water can be realized by the forward and reverse rotation of the first driving member 14, without the need to set other control valves for switching the passages, so that the overall structure is simple and reliable, the cost is low, and the system structure is changed little.

[0171] It should be noted that, when the second driving member 61 is in the forward rotation state, the flow direction of the additives in the second liquid supply link 2 is a first flow direction (as shown by the flow direction). Figure 7 to Figure 12 When the second driving member 61 is in the reverse rotation state, the flow direction of the clean water in the second liquid supply link 2 is a second flow direction (as shown by the flow direction). Figure 1 to Figure 6 The first flow direction is opposite to the second flow direction.

[0172] It can be understood that the first driving member 14 and the second driving member 61 of the foregoing embodiment can be connected to a main control board, and the main control board (not shown in the figure) is at least used to control the opening and closing of the first driving member 14 and the second driving member 61.

[0173] Exemplarily, taking the additives as the wax emulsion curing liquid, when the cleaning equipment 200 is parked in the cleaning base station 100, the main control board can control the second driving member 61 to automatically rotate forward, so that the second driving member 61 drives the concentrated curing liquid in the additive module 5 to be transported from the second communication port 52 to the second interface 72 of the multi-way joint 7 through the additive delivery pipeline 21. At the same time, the first driving member 14 can control the clean water of the clean water source 4 to be transported to the first interface 71 of the multi-way joint 7 through the first one-way valve 15 and the standby container 13, and through the first liquid supply link 1, so as to be mixed with the concentrated curing liquid transported from the second interface 72 of the multi-way joint 7 in the multi-way joint 7, and then be output to the total liquid outlet pipeline 3 through the third interface 73 of the multi-way joint 7, and then the mixed target curing liquid is output to the cleaning tank of the cleaning base station 100 to supply the cleaning member of the cleaning equipment 200, or output to the clean water box of the cleaning equipment 200 to supply the cleaning member of the cleaning equipment 200 when the cleaning equipment 200 performs ground curing. After the ground curing is completed, the main control board can control the second driving member 61 to automatically rotate reversely, so that the clean water of the first liquid supply link 1 enters the second liquid supply link 2 through the second driving member 61, so as to clean the second liquid supply link 2.

[0174] In the first embodiment of the control unit 6, as shown in Figure 1 to Figure 6 the second liquid supply link 2 further comprises a drain line 22, wherein the input end 11 of the drain line 22 is connected to the first communication port 51 of the additive module 5, and the output end of the drain line 22 is used to communicate with the clean water box of the cleaning device 200, or the output end 12 of the drain line 22 is used to communicate with the cleaning tank 120 of the cleaning base station 100. Understandably, in the present embodiment, the second liquid supply link 2 at least comprises the additive delivery line 21 and the drain line 22. When the output end of the drain line 22 communicates with the clean water box of the cleaning device 200, the target additive diluted by clean water can be input into the line of the cleaning device 200 to the clean water box of the cleaning device 200 when the control unit 6 is in the first state, so that the target additive in the clean water box can be delivered to the cleaning member of the cleaning device 200 while the cleaning device 200 travels on the surface to be cleaned. When the control unit 6 is in the second state, clean water can be driven to the line of the cleaning device 200 connected to the clean water box through the drain line 22, and the line of the cleaning device 200 with residual additive can be cleaned, so that the line flowing through the additive in the cleaning base station 100 and the cleaning device 200 can be cleaned.

[0175] Further exemplarily, in some embodiments, the additive liquid path system 300 can further comprise a multi-way drain connector 9 (see Figure 1 to Figure 4 or Figure 3 , wherein one interface of the multi-way drain connector 9 is used to communicate with the output end of the total liquid outlet line 3, one interface is used to communicate with the clean water output end of the second liquid supply link 2, and one interface is used to communicate with the cleaning tank 120 of the cleaning base station 100 or the clean water box of the cleaning device 200, etc. By providing the multi-way drain connector 9, the line connector can also be simplified, so that the connection of the cleaning base station 100 or the cleaning device 200 is simpler.

[0176] Exemplarily, in the present embodiment, when there is clean water in the clean water source 4 and / or the standby container 13 before the second driving member 61 enters the reverse state, the clean water can be first driven into the total liquid outlet line 3 by the first driving member 14 to flush the total liquid outlet line 3. After the total liquid outlet line 3 is flushed, the second driving member 61 is controlled to enter the reverse state, so that the clean water of the first liquid supply link 1 enters the additive delivery line 21 from the output end 12 thereof, and is discharged along the drain line 22, thereby realizing the flushing of the additive delivery line 21.

[0177] In the first embodiment of the control unit 6, as shown in Figure 4As shown, the drain pipeline 22 is further provided with a third one-way valve 221. The third one-way valve 221 is configured to be one-way conductive in the direction from the first communication port 51 of the additive module 5 to the cleaning tank 120 of the cleaning base station 100 or the cleaning water box of the cleaning device 200, so as to prevent the liquid in the cleaning tank 120 of the cleaning base station 100 or the cleaning water box of the cleaning device 200 from flowing back to the additive module 5, and the third one-way valve 221 has a third preset pressure limit value, and when the fluid pressure between the first communication port 51 of the additive module 5 and the third one-way valve 221 is greater than the third preset pressure limit value, the third one-way valve 221 is opened to make the drain pipeline 22 conductive.

[0178] As shown in Figure 1 to Figure 4 and Figure 3 , one interface of the multi-way discharge joint 9 of the additive liquid pipeline system 300 is used to communicate with the output end of the total liquid outlet pipeline 3, one interface is used to communicate with the output end of the drain pipeline 22, and one interface is used to communicate with the cleaning tank 120 of the cleaning base station 100 or the cleaning water box of the cleaning device 200, etc. As shown in Figure 4 , when the second driving member 61 is in the forward rotation state to extract the additive, the mixed target additive is output from the total liquid outlet pipeline 3 (specifically, the double-dot dashed arrow in Figure 1 to Figure 4 ) to the multi-way discharge joint 9 for discharge, and since the third one-way valve 221 cannot be conductive in the direction from the multi-way discharge joint 9 to the first communication port 51 of the additive module 5, it is obvious that the target additive such as the mixed maintenance liquid at the multi-way discharge joint 9 can be prevented from entering the additive module 5 through the third one-way valve 221 along the drain pipeline 22 and the first communication port 51, and then being discharged from the second communication port 52 to the additive delivery pipeline 21, thereby affecting the configuration of the dilution ratio of the target additive.

[0179] In the second specific embodiment of the control unit 6, as shown in Figure 3 , the control unit 6 includes a control valve 62 and a second driving member 61, and the control valve 62 is connected between the water source 4 and the first communication port 51 of the additive module 5. It should be noted that in the embodiment without the spare container 13, the control valve 62 can be directly connected to the water source 4 (see Figure 4 and Figure 3 ), or indirectly connected to the water source 4 through the first liquid supply link 1, etc. In addition, the water source 4 described herein can be a water tank (see Figure 3 ), or a tap water source connected to the cleaning base station 100, etc., which can be determined according to actual conditions.

[0180] Further as shown in Figure 5 to Figure 12As shown, the second drive unit 61 is disposed in the additive delivery pipeline 21, and the second drive unit 61 is located between the second connection port 52 of the additive module 5 and the output end 12 of the first liquid supply link 1. In this second specific embodiment, the first state is that the control valve 62 is in the closed state and the second drive unit 61 is in the forward rotation state. The second state is that the control valve 62 is in the open state and the second drive unit 61 is in the forward rotation state.

[0181] In the first state, the control valve 62 is closed to prevent water from the clean water source 4 or the clean water from the first liquid supply link 1 from entering the second liquid supply link 2. The second drive unit 61 is in a forward rotation state to drive the additive in the additive module 5 to be discharged from the second connection port 52 through the additive delivery pipeline 21 to the output end 12 of the first liquid supply link 1, so as to control and realize the automatic delivery of the additive.

[0182] In the second state, the flow channel from the additive in the additive module 5 to the second connection port 52 is closed, and the control valve 62 is open to allow clean water from the clean water source 4 or the first liquid supply link 1 to enter the additive delivery pipeline 21 from the first connection port 51 and the second connection port 52 of the additive module 5. The second drive unit 61 is in a forward rotation state to drive the clean water in the clean water source 4 to enter the additive delivery pipeline 21 from the first connection port 51 and the second connection port 52 of the additive module 5, so as to clean the additive delivery pipeline 21 at least by means of clean water.

[0183] like Figure 7 or Figure 8 As shown, in some embodiments, when the first liquid supply link 1 is equipped with a backup container 13, the backup container 13 is connected between the clean water source 4 and the output end 12 of the first liquid supply link 1. The backup container 13 is used to contain backup clean water and to supply clean water flow; the input end of the control valve 62 is connected between the backup container 13 and the output end 12 of the first liquid supply link 1. In this way, when the clean water source 4 is dry, the clean water in the backup container 13 can be input to the second liquid supply link 2 through the control valve 62.

[0184] When the first liquid supply link 1 does not have a spare container 13, in the first example, as Figure 5 to Figure 10 and Figure 5 to Figure 12 As shown, the clean water source 4 can be a clean water tank, and the second liquid supply link 2 can also include a drain pipe 22. One end of the drain pipe 22 is directly connected to the clean water source 4 at the input end 11 of the first liquid supply link 1, and the other end of the drain pipe 22 is connected to the first communication port 51 of the additive module 5. A control valve 62 is located on the drain pipe 22. In the first state, as shown... Figure 5As shown, control valve 62 is closed to prevent clean water from the clean water tank from entering the additive module 5 from the drain pipe 22 through the first connection port 51; the second drive unit 61 rotates forward to drive the concentrated additive in the additive module 5 from the second connection port 52 through the additive delivery pipe 21 (see...). Figure 6 (Dashed arrow) discharges to connect with the first fluid supply link 1 (see...) Figure 7 (Solid arrow in the middle) The delivered clean water is mixed into the target additive.

[0185] In the second state, such as Figure 8 As shown, the control valve 62 is opened to allow the clean water in the clean water tank to enter the additive delivery pipeline 21 from the drain pipe 22, the first connection port 51, and the second connection port 52 and be discharged. The second drive unit 61 rotates forward to drive the delivery of clean water in the second liquid supply link 2, so that the clean water flushes the entire second liquid supply link 2, thereby reducing the probability of blockage, corrosion and other problems in the second liquid supply link 2 due to residual additives.

[0186] It should be noted that, specifically in this example, the second liquid supply link 2 can be connected to the liquid collection container 8, which in turn is connected to the wastewater tank. This allows the wastewater generated after rinsing the second liquid supply link 2 with clean water to be directly pumped into the wastewater tank and discharged. Alternatively, it can be directly connected to a sewer or discharged externally. Alternatively, it can be connected to the clean water box of the cleaning device 200 to further rinse the pipelines in the cleaning device 200 that replenish the target additive.

[0187] In the second example, such as Figure 7 and Figure 7 As shown, the clean water source 4 can be a clean water tank. The first liquid supply link 1 is also equipped with a heating element 16. The second liquid supply link 2 may also include a drain pipe 22. One end of the drain pipe 22 is connected to the first liquid supply link 1 after the heating element 16, and the other end is connected to the first communication port 51 of the additive module 5. The control valve 62 is located in the drain pipe 22. In the first state, as shown... Figure 7 As shown, control valve 62 is closed to prevent clean water from the first liquid supply link 1 from entering the additive module 5 from the drain pipe 22 through the first connection port 51; the second drive unit 61 rotates forward to drive the concentrated additive in the additive module 5 from the second connection port 52 through the additive delivery pipe 21 (see... Figure 8 (Dashed arrow) discharges to connect with the first fluid supply link 1 (see...) Figure 9 (Solid arrow in the middle) The delivered clean water is mixed into the target additive.

[0188] In the second state, such as Figure 10As shown, the control valve 62 is opened to allow the clean water in the first liquid supply link 1 to be discharged from the drain line 22, the first communication port 51, the second communication port 52 into the additive delivery line 21, and the second driving member 61 is rotated in the forward direction to drive the delivery of the clean water in the second liquid supply link 2, so that the clean water flushes the entire second liquid supply link 2, thereby reducing the probability of the second liquid supply link 2 being blocked, corroded, etc. due to the residual additive.

[0189] It should be noted that, in the third example, the second liquid supply link 2 is connected to the sump container 8, and the sump container 8 is connected to the sewage tank, so that the sewage formed by the clean water flushing the second liquid supply link 2 can be directly pumped into the sewage tank for discharge, or can be directly connected to the sewer or externally discharged. Alternatively, the second liquid supply link 2 can also be connected to the clean water tank of the cleaning device 200 to further flush the pipeline of the cleaning device 200 for replenishing the target additive.

[0190] In the third example, as shown in Figure 9 and Figure 9 , the source of the clean water for flushing the second liquid supply link 2 can include the clean water in the cleaning tank 120 (corresponding to the sump container 8) of the cleaning base station 100, and the second liquid supply link 2 can further include the drain line 22, one end of which is connected to the cleaning tank 120 and the other end of which is connected to the first communication port 51 of the additive module 5. The control valve 62 is arranged in the drain line 22. In the first state, as shown in Figure 9 , the control valve 62 is closed to prevent the clean water or other liquid in the cleaning tank 120 from passing through the first communication port 51 from the drain line 22 into the additive module 5, and the second driving member 61 is rotated in the forward direction to drive the concentrated additive in the additive module 5 to be discharged from the second communication port 52 through the additive delivery line 21 (see the dashed arrow in Figure 10 ) to be mixed with the clean water delivered from the first liquid supply link 1 (see the solid arrow in Figure 11 ) to form the target additive.

[0191] In the second state, as shown in Figure 12 , the control valve 62 is opened to allow the clean water in the cleaning tank 120 of the cleaning base station 100 to be discharged from the drain line 22, the first communication port 51, the second communication port 52 into the additive delivery line 21, and the second driving member 61 is rotated in the forward direction to drive the delivery of the clean water in the second liquid supply link 2, so that the clean water flushes the entire second liquid supply link 2, thereby reducing the probability of the second liquid supply link 2 being blocked, corroded, etc. due to the residual additive.

[0192] It should be noted that, in the third example, the second liquid supply link 2 is connected to the sump container 8, and the sump container 8 is connected to the sewage tank, so that the sewage formed by the clean water flushing the second liquid supply link 2 can be directly pumped into the sewage tank for discharge, or can be directly connected to the sewer or externally discharged. Alternatively, the second liquid supply link 2 can also be connected to the clean water tank of the cleaning device 200 to further flush the pipeline of the cleaning device 200 for replenishing the target additive. Figure 11 Figure 11 ​As shown, the clean water source 4 connected to the first liquid supply link 1 and the clean water source for flushing the second liquid supply link 2 can be different sources, for example, the clean water source 4 connected to the first liquid supply link 1 can be a clean water tank of the cleaning base station or a tap water source or a clean water box of the cleaning device, and the clean water source for flushing the second liquid supply link 2 can be the cleaning tank 120 of the cleaning base station 100, corresponding to the clean water in the liquid collection container 8.

[0193] In the second embodiment of the control unit 6, as shown in Figure 11 and Figure 12 The first liquid supply link 1 is provided with a standby container 13, wherein the standby container 13 is connected between the clean water source 4 and the output end 12 of the first liquid supply link 1, and the standby container 13 is used to contain standby clean water and provide a clean water flow. The input end of the control valve 62 is connected between the standby container 13 and the output end 12 of the first liquid supply link 1. When the clean water source 4 is out of water, by opening the control valve 62, under the drive of the second driving member 61, the standby clean water in the standby container 13 can enter the additive delivery pipeline 21 in sequence through the drain pipeline 22, the first communication port 51 and the second communication port 52 of the additive module 5 and be discharged, so as to realize cleaning of at least the additive delivery pipeline 21.

[0194] In some embodiments of the present disclosure, as shown in Figure 11 To realize the function that the additive module 5 can output additives in the first state and the additive module 5 does not output additives only to provide a clean water flow in the second state, the additive module 5 includes a mounting shell 53 and a liquid storage container 54, the mounting shell 53 has a first inner cavity 531 formed inside, and the mounting shell 53 is provided with a switching cavity 532, and the first communication port 51 and the second communication port 52 of the additive module 5 are in communication with the switching cavity 532. The liquid storage container 54 is detachably installed in the first inner cavity 531 and is provided with a liquid outlet 542, and the liquid storage container 54 is used to contain additives.

[0195] When the control unit 6 is in the first state, the control unit 6 controls the liquid outlet 5412 of the liquid storage container 54 to be opened and communicated with the switching cavity 532, so as to drive the additives in the liquid storage container 54 to enter the switching cavity 532, and make the additives in the switching cavity 532 discharged from the second communication port 52 through the additive delivery pipeline 21.

[0196] When the control unit 6 is in the second state, the control unit 6 controls the switching cavity 532 to be isolated from the liquid storage container 54, and the clean water enters the second liquid supply link 2 and passes through one of the first communication port 51 and the second communication port 52, the switching cavity 532, the other of the first communication port 51 and the second communication port 52 in the additive module 5 in sequence.

[0197] Exemplarily, to set the switching cavity 532, as shown in Figure 12As shown, the mounting shell 53 is provided with a switching member 536, wherein, as shown in Figure 5 As shown, the switching member 536 is concavely provided with a switching cavity 532, and is provided with a first joint 5361 and a second joint 5362, the first joint 5361 is open to a first communication port 51 in communication with the switching cavity 532, and the second joint 5362 is open to a second communication port 52 in communication with the switching cavity 532.

[0198] In the first specific embodiment of the control unit 6, as shown in Figure 6 As shown, when the second driving member 61 of the control unit 6 is in the second state, i.e. in the reverse rotation state, the second driving member 61 can control the switching cavity 532 to be isolated from the liquid storage container 54, and the clean water delivered by the first liquid supply link 1 can enter the second liquid supply link 2, and then sequentially pass through the second communication port 52, the switching cavity 532 and the first communication port 51 to be discharged through the drainage pipeline 22 in the additive module 5.

[0199] In the first example of the second specific embodiment of the control unit 6, as shown in Figure 13 As shown, when the control unit 6 is in the second state, i.e. the control valve 62 is open and the second driving member 61 is in the forward rotation state, the control valve 62 can be opened to control the switching cavity 532 to be isolated from the liquid storage container 54, and the clean water of the clean water source 4 can directly enter the second liquid supply link 2 through the control valve 62, and then sequentially pass through the first communication port 51, the switching cavity 532 and the second communication port 52 to be discharged in the additive module 5.

[0200] In some embodiments of the present disclosure, as shown in Figure 13 and Figure 15 In order to achieve the isolation or communication between the liquid storage container 54 and the switching cavity 532, the mounting shell 53 is provided with a docking port 533, the docking port 533 is in communication with the first inner cavity 531 and the switching cavity 532, and is used to dock and communicate with the liquid outlet 542 of the liquid storage container 54.

[0201] The additive module 5 further comprises a top valve assembly 56 and a valve plug assembly 55, the top valve assembly 56 is movably arranged in the switching cavity 532, and the top valve assembly 56 comprises a top pressing member 561 and a first elastic member 562, wherein the first elastic member 562 is connected between the first end of the top pressing member 561 and the cavity wall of the switching cavity 532, and the second end of the top pressing member 561 is exposed to the docking port 533. The liquid outlet 542 of the liquid storage container 54 is provided with a valve plug mounting cavity 543 for mounting the valve plug assembly 55, wherein the valve plug assembly 55 is movably arranged in the valve plug mounting cavity 543, and the valve plug assembly 55 comprises a plug sealing member 551 and a second elastic member 552, the second elastic member 552 is connected between the first end of the plug sealing member 551 and the cavity wall of the valve plug mounting cavity 543.

[0202] In the state that the liquid storage container 54 is not installed in the first inner cavity 531, the second end of the sealing plug 551 of the valve plug assembly 55 elastically abuts against the inner periphery of the liquid outlet 542 under the elastic force applied by the second elastic member 552, so as to seal the liquid outlet 542. It should be noted that the inner periphery of the liquid outlet 542 refers to the inner peripheral wall of the liquid outlet and the edge near the inner peripheral wall.

[0203] Correspondingly, in the state that the liquid storage container 54 is installed in the first inner cavity 531, the second end of the pressing plug 561 of the top valve assembly 56 presses the sealing plug 551 of the valve plug assembly 55 under the elastic force applied by the first elastic member 562, so that the sealing plug 551 is separated from the inner periphery of the liquid outlet 542 to open the liquid outlet 542. It should be noted that when the liquid storage container 54 is installed in the first inner cavity 531, the second end of the pressing plug 561 can always press the sealing plug 551 to ensure that the liquid outlet 542 of the liquid storage container 54 can be stably and reliably opened.

[0204] Exemplarily, in order to improve the sealing performance of the additive module 5, the additive module 5 further comprises a first sealing member 57 and a second sealing member 58. The first sealing member 57 is provided with a first insertion hole 571 which is in communication with the adapter cavity 532. The second sealing member 58 is provided with a second insertion hole 581 which is in communication with the liquid outlet 542 of the liquid storage container 54. The first sealing member 57 is inserted into the counter port 533, and the liquid outlet 542 can be in communication with the adapter cavity 532 through the first insertion hole 571. Correspondingly, the second sealing member 58 is installed on the liquid outlet 542 of the liquid storage container 54, and the valve plug installation cavity 543 can be in communication with the first insertion hole 571 through the second insertion hole 581, so that the liquid outlet 542 is in communication with the counter port 533.

[0205] It should be noted that in the above structure, the first end of the pressing plug 561 of the top valve assembly 56 is located in the adapter cavity 532 and is connected with the first elastic member 562. In the state that the liquid storage container 54 is installed in the first inner cavity 531, the second end of the pressing plug 561 penetrates through the first insertion hole 571 and is exposed outside the first insertion hole 571, and penetrates through the second insertion hole 581 to abut against the sealing plug 551 of the valve plug assembly 55 to separate the sealing plug 551 from the inner periphery of the liquid outlet 542 to open the liquid outlet 542. At this time, the additive in the liquid storage container 54 can enter the adapter cavity 532 through the second insertion hole 581 at the liquid outlet 542 and the first insertion hole 571 at the counter port, and then flow out of the additive module 5 through the second communication port 52.

[0206] It is also to be noted that the second end of the top pressing member 561 has a radial gap with the first insertion hole 571 and the second insertion hole 581, so that the liquid outlet 542 is always in an open state, and the interface is also in an open state when the additive is output, facilitating the additive to enter the adapter cavity 532 through the radial gap at the second insertion hole 581 and the radial gap at the first insertion hole 571 in sequence, and then be transported to the additive conveying pipeline 21 through the second communication port 52, on the one hand to realize the conveying of the additive, and on the other hand to ensure that the conveyed additive will not easily leak.

[0207] In some embodiments of the present disclosure, when the liquid storage container 54 is installed in the first inner cavity 531, and the top valve assembly 56 and the valve plug assembly are not subjected to external force, the first end of the top pressing member 561 abuts against the inner periphery of the interface 533 under the elastic force applied by the first elastic member 562, so as to seal the interface 533 and separate the liquid outlet 542 of the liquid storage container 54 from the adapter cavity 532. The elastic force applied by the second elastic member 552 to the sealing plug 551 is smaller than the elastic force applied by the first elastic member 562 to the top pressing member 561, so that the maximum retraction distance of the top rod 561 is smaller than the retraction distance of the sealing plug 551 caused by the top pressing of the top rod 561, so as to ensure that the first end of the top rod 561 can always block the first insertion hole 571 without being driven by external force, so as to stably prevent the additive in the liquid storage container 54 from entering the adapter cavity 532 through the first insertion hole 571 (corresponding to the interface 533), so as to maintain the closed state of the liquid storage container 54.

[0208] Exemplarily, the second end of the top pressing member 561 passes through the first insertion hole 571 and is exposed outside the first insertion hole 571, and extends through the second insertion hole 581 to abut against the sealing plug 551 of the valve plug assembly 55 in the valve plug mounting cavity 543, so that the sealing plug 551 is separated from the inner periphery of the liquid outlet 542 to open the liquid outlet 542, and the first end of the top pressing member 561 abuts against the first elastic member 562 on the side of the first insertion hole 571 close to the adapter cavity 532, so as to block the first insertion hole 571 on the side of the adapter cavity, and finally separate the interface 533 from the adapter cavity 532, so as to prevent the additive from entering the adapter cavity 532 through the liquid outlet 542.

[0209] It is to be noted that when the second liquid supply link needs to be cleaned, the second driving member 61 in the first specific embodiment of the control unit 6 can be reversed, or the control valve 62 in the second specific embodiment of the control unit 6 can be opened, so that the top valve assembly 56 and the valve plug assembly are not subjected to external force.

[0210] In some embodiments of the present disclosure, in the case that the liquid storage container 54 is installed in the first inner cavity 531 and the control unit 6 is in the first state, in order to realize the output of the additive in the liquid storage container 54 to the additive delivery pipeline 21, the control unit 6 extracts the air in the adapter cavity 532 to move the top pressing piece 561 away from the outlet 542 to the first end of the top pressing piece 561 away from the inner periphery of the abutment 533 to open the abutment 533, and the sealing piece 551 moves towards the outlet 542 under the elastic restoring force of the second elastic piece 552. In the case that the top pressing piece 561 moves away from the outlet 542 to the limit position, the sealing piece 551 is in the position away from the inner periphery of the outlet 542, and the abutment 533 is in communication with the outlet 542.

[0211] In the case that the liquid storage container 54 is installed in the first inner cavity 531 and the control unit 6 is in the second state, in order to realize the isolation of the outlet 542 of the liquid storage container 54 from the adapter cavity 532, so that the additive in the liquid storage container 54 cannot enter the adapter cavity 532 from the outlet 542, the control unit 6 controls the clean water to enter the adapter cavity 532 to push the top pressing piece 561 of the top valve assembly 56 to move towards the outlet 542 to the first end of the top pressing piece 561 abutting the inner periphery of the abutment 533 to seal the abutment 533, thereby preventing the additive in the liquid storage container 54 from entering the adapter cavity 532 through the abutment 533.

[0212] It should be noted that, as shown in Figure 4 , Figure 8 and Figure 13 , the mounting shell 53 is provided with a partition 534, and the cavity in the mounting shell 53 can be divided into the first inner cavity 531 and the second inner cavity 535 by the partition 534. On the side of the second inner cavity, the mounting shell 53 is provided with the first liquid flow port 537 and the second liquid flow port 538 which are in communication with the second inner cavity 535. The first liquid flow port 537 is used for the input of the clean water from the clean water source 4, and the second liquid flow port 538 is used at least for the outflow of the additive or the clean water.

[0213] For example, in the first example of the second specific embodiment of the control unit 6, as shown in Figure 16As shown, one end of the drain pipeline 22 in the second liquid supply link 2 can be connected to the clean water source 4 through the first liquid flow port 537, and the other end can be connected to the first joint 5361 of the adapter 536 to communicate with the first communication port 51, and the middle of the drain pipeline 22 is provided with a control valve 62. One end of the additive delivery pipeline 21 in the second liquid supply link 2 can be connected to the cleaning tank 120 of the cleaning base station 100, the clean water box of the cleaning device 200, etc. through the second liquid flow port 538, and the other end can be connected to the second joint 5362 of the adapter to communicate with the second communication port 52. In order to make the overall structure more compact, and to ensure the reliability and stability of the liquid flow delivery, the additive delivery pipeline 21, the drain pipeline 22, the control valve 62 and the second driving member 61 are all built into the second inner cavity 535.

[0214] It should be further pointed out that, as shown in Figure 13 and Figure 14 , the liquid storage container 54 can further include an end cover 546 and an inner tube 547, wherein the end cover 546 is provided on the periphery of the second sealing member 544 and covers the liquid outlet 542, and the end cover 546 is axially provided with a relief hole (not shown in the figure) for the top valve assembly 56 to pass through and be inserted into the second insertion hole 5441. When the liquid storage container 54 is installed in the mounting shell 53 of the additive module 5, the top rod 561 is sequentially inserted into the first insertion hole 571, the relief hole and the second insertion hole 5441 to extend into the valve plug installation cavity 543 to press the sealing plug 551. In addition, the inner tube 547 is installed in the inner cavity of the liquid storage container 54 and communicates with the bottom of the inner cavity of the liquid storage container 54. The valve plug assembly 55 is installed in the inner tube 547, and the second sealing member 544 is encapsulated at the corresponding position of the liquid outlet 542, so that the additive in the liquid storage container 54 can be output from the liquid storage container 54 through the radial gap of the second insertion hole 5441 of the second sealing member 544 via the inner tube 547.

[0215] In some embodiments of the present disclosure, as shown in Figure 16 and Figure 7 , in order to compensate for the pressure difference between the inside and outside of the liquid storage container 54, a flexible inner container 545 is arranged in the liquid storage container 54, wherein one end of the flexible inner container 545 communicates with the outside of the liquid storage container 54 and the other end is a blind end. In this way, the probability of the additive in the liquid storage container 54 contacting the outside can be reduced, and the additive in the liquid storage container 54 can be prevented from deteriorating or condensing after contacting air.

[0216] Exemplarily, the arrangement mode of the flexible inner container 545 and the liquid storage container 54 includes but is not limited to buckle connection, screw connection, combined connection of buckle and screw, and of course, other existing or newly created structural connections can also be used.

[0217] Also exemplary, the thickness of the flexible inner container 545 is designed to be 0.1mm~1mm. The expansion volume of the flexible inner container 545 is theoretically required to be greater than or equal to the volume of the liquid storage container 54, so that when the additive is extracted from the liquid storage container 54, the flexible inner container 545 will expand to achieve the pressure balance of the liquid storage container 54 (see Figure 13 ), until the internal and external pressure of the liquid storage container 54 is balanced.

[0218] The embodiments of the present disclosure also provide a cleaning device 200 for cleaning a surface to be cleaned, such as Figure 14 As shown, the cleaning device 200 comprises a body 210 and an additive liquid path system 300 arranged in the body 210.

[0219] In the embodiments of the present disclosure, the additive liquid path system 300 comprises a first liquid supply link 1, a second liquid supply link 2 and a control unit 6, wherein the first liquid supply link 1 is used for conveying clean water, the second liquid supply link 2 comprises but is not limited to conveying additives, and the control unit 6 comprises but is not limited to controlling the additive liquid path system 300 to convey target additives, and controlling the pipeline of the additive liquid path system 300 to be cleaned by clean water. Exemplarily, as shown in Figure 17 , the first liquid supply link 1 has an input end 11 and an output end 12, wherein the input end 11 is connected to a clean water source 4, and the output end 12 is used to output clean water.

[0220] In the embodiments of the present disclosure, as shown in Figure 18 , the second liquid supply link 2 comprises an additive conveying pipeline 21, which is mainly used for conveying additives, such as conveying concentrated wax emulsion curing liquid, so as to mix with the clean water conveyed by the first liquid supply link 1 to form target curing liquid, and then conveyed to the cleaning area of the cleaning device 200 and sprayed on the cleaning element such as the mop of the cleaning device 200, or directly sprayed on the surface to be cleaned, or sprayed into the cleaning tank 120 of the cleaning base station 100, etc.

[0221] Further as shown in Figure 18 , the second liquid supply link 2 is also provided with an additive module 5, which is mainly used for containing additives. In order to realize that the second liquid supply link 2 not only has the function of conveying additives, but also has the function of self-cleaning, the additive module 5 has a first communication port 51 and a second communication port 52 which are in communication with each other, wherein the second communication port 52 and the output end 12 of the first liquid supply link 1 are communicated through the additive conveying pipeline 21.

[0222] It should be noted that the first communication port 51 can be used for inputting or outputting clean water, and the second communication port 52 can be used for outputting additives, and can also be used for inputting or outputting clean water, which can be determined according to the specific structure of the additive liquid path system 300 and actual needs.

[0223] It should be noted that the additive module 5 can be installed in the dust collection bin of the cleaning base station 100, or can be installed in other suitable positions of the cleaning base station 100.

[0224] For example Figure 19 As shown, the control unit 6 is connected to the second liquid supply link 2, wherein the control unit 6 has a first state and a second state. When the control unit 6 is in the first state, the control unit 6 controls the additive in the additive module 5 to be transported from the second communication port 52 to the output end 12 of the first liquid supply link 1 through the additive delivery pipeline 21, so that the additive output by the additive delivery pipeline 21 can be mixed with the clean water transported by the first liquid supply link 1 to finally form the target additive for actual use, without the user needing to ask a professional agency to add the maintenance liquid or other target additive, or the user needing to add the maintenance liquid or other target additive with both hands, that is, it is beneficial to realize automatic addition of the maintenance liquid or other target additive, so as to realize the additional function of automatic maintenance of the surface to be cleaned, such as the ground.

[0225] It should be noted that when the additive is the maintenance liquid, the additive delivery pipeline 21 is prone to condensation in the normal use process of the user due to factors such as the small pipeline and the high concentration of the additive transported. When the additive is a high-concentration disinfectant or other liquid, the additive is prone to corrode the additive delivery pipeline 21.

[0226] When the control unit 6 is in the second state, the control unit 6 controls the clean water from the clean water source 4 to enter the second liquid supply link 2 to at least clean the additive delivery pipeline 21 with the clean water, so that at least part of the additive remaining in the additive delivery pipeline 21 after the first state is discharged, so as to realize the self-cleaning function of the additive delivery pipeline 21 after the additive is delivered, reduce the probability of pipeline blockage, corrosion and other problems caused by long-term retention of the additive in the pipeline of the cleaning device 200, and reduce the probability of condensation problems in the liquid pipeline of the cleaning system 1000, thereby ensuring the liquid flow delivery function of the pipeline, improving the use reliability of the cleaning device 200, and facilitating the improvement of the user's use experience.

[0227] It should be noted that the first state described herein is mainly the state of the additive liquid path system 300 when conveying additives, and the second state is mainly the state of the additive conveying pipeline 21 of the second liquid supply link 2 of the additive liquid path system 300 when self-cleaning. The user can select the control unit 6 to be in the first state or the second state according to actual needs, or the control unit 6 controls its own state according to the current task process of the cleaning device 200. For example, after the cleaning device 200 finishes cleaning the surface to be cleaned, and receives an instruction to maintain the surface to be cleaned, the control unit 6 is started and in the first state, and the second liquid supply link outputs additives (such as maintenance liquid). After the cleaning device 200 completes the current maintenance task, and the cleaning device 200 returns to the cleaning base station 100, the control unit 6 is started and in the second state, and the additive conveying pipeline is cleaned.

[0228] The embodiments of the present disclosure also provide a cleaning system 1000, as shown in Figure 19 The cleaning system 1000 includes a cleaning base station 100 and a cleaning device 200. The cleaning base station 100 is used to maintain the cleaning device 200, and the cleaning device 200 is used to clean a surface to be cleaned. The cleaning base station 100 includes a base station body 110 and an additive liquid path system 300. The additive liquid path system 300 is arranged in the base station body 110, and the base station body 110 is provided with a parking position for the cleaning device 200 to park. Alternatively, the cleaning device 200 includes a machine body 210 and an additive liquid path system 300, and the additive liquid path system 300 is arranged in the machine body 210.

[0229] In the embodiments of the present disclosure, as shown in Figure 19 and Figure 19 , or Figure 19 and Figure 20 , the additive liquid path system 300 includes a first liquid supply link 1, a second liquid supply link 2, and a control unit 6. The first liquid supply link 1 can be used to convey clean water, the second liquid supply link 2 includes but is not limited to conveying additives, and the control unit 6 includes but is not limited to controlling the additive liquid path system 300 to convey target additives and controlling the pipeline of the additive liquid path system 300 to be cleaned by clean water. Exemplarily, the first liquid supply link 1 has an input end 11 and an output end 12. The input end 11 is connected to the clean water source 4, and the output end 12 is used to output clean water.

[0230] In the embodiments of the present disclosure, as shown in Figure 1 and Figure 2 , or Figure 5 and Figure 6As shown, the second liquid supply link 2 comprises an additive delivery pipeline 21, which is mainly used for delivering additives, such as concentrated wax emulsion curing fluid, to be mixed with the clean water delivered by the first liquid supply link 1 into the target curing fluid, and then delivered by the pipeline to the cleaning area of the cleaning device 200 and sprayed onto the cleaning elements such as the mop of the cleaning device 200, or directly sprayed to the surface to be cleaned, or sprayed into the cleaning tank 120 of the cleaning base station 100, etc.

[0231] Further Figure 1 and Figure 2 or Figure 5 and Figure 6 As shown, the second liquid supply link 2 is also provided with an additive module 5, which is mainly used for containing additives. In order to realize that the second liquid supply link 2 not only has the function of delivering additives, but also has the function of self-cleaning, the additive module 5 has a first communication port 51 and a second communication port 52 which are in communication with each other, wherein the second communication port 52 and the output end 12 of the first liquid supply link 1 are communicated through the additive delivery pipeline 21.

[0232] It should be noted that the first communication port 51 can be used for inputting or outputting clean water, and the second communication port 52 can be used for outputting additives, and can also be used for inputting or outputting clean water, which can be determined according to the specific structure of the additive liquid system 300 and actual needs.

[0233] It should be further noted that the additive module 5 can be installed in the dust collection bin of the cleaning base station 100, or can be installed at other suitable positions of the cleaning base station 100.

[0234] Further Figure 1 and Figure 2 or Figure 5 and Figure 6 Figure 1 Figure 2 Figure 5 Figure 6 As shown, the control unit 6 is connected to the second liquid supply link 2, wherein the control unit 6 has a first state and a second state. Wherein, when the control unit 6 is in the first state, the control unit 6 controls the additives in the additive module 5 to be delivered from the second communication port 52 to the output end 12 of the first liquid supply link 1 through the additive delivery pipeline 21, so that the additives delivered by the additive delivery pipeline 21 can be mixed with the clean water delivered by the first liquid supply link 1 to form the target additive for actual use. The user does not need to ask professional institutions to add curing fluid and other target additives, nor does the user need to add curing fluid and other target additives with both hands, that is, it is beneficial to realize the automatic addition of curing fluid and other target additives, so as to realize the automatic curing and other additional functions of the surface to be cleaned.

[0235] It should be noted that, in the case of the additive being the curing liquid, the additive delivery pipeline 21 is prone to condensation in the normal use process of the user due to the small pipeline and the high concentration of the delivered additive. In the case of the additive being a high-concentration disinfectant liquid, the additive is prone to corrode the additive delivery pipeline 21.

[0236] In the second state of the control unit 6, the control unit 6 controls the clean water from the clean water source 4 to enter the second liquid supply link 2 to at least clean the additive delivery pipeline 21 with the clean water, so that at least part of the additive remaining in the additive delivery pipeline 21 after the first state is discharged, so as to realize the self-cleaning function of the additive delivery pipeline 21 after the delivery of the additive, reduce the probability of pipeline blockage, corrosion and other problems caused by the long-term retention of the additive in the pipeline of the cleaning base station 100 or the cleaning device 200, and reduce the probability of condensation problems in the liquid pipeline of the cleaning system 1000, thereby ensuring the liquid flow delivery function of the pipeline, improving the use reliability of the cleaning base station 100 or the cleaning device 200, and improving the user's use experience.

[0237] It should be noted that the structure of the additive liquid system 300 provided in the cleaning device 200 and the cleaning system 1000 described above can adopt the structure of the additive liquid system 300 provided in the cleaning base station 100, which will not be described in detail here.
