Description

TECHNICAL FIELDThe present application relates to the technical field of intelligent cleaning, in particular to a base station for a robot wiper and a robot wiper system.PRIOR ARTWith the continuous development of automation and smart technology, smart cleaners are becoming more and more popular. Among other things, wiping robots can take over the automatic wiping of door and window surfaces, in particular glass surfaces, without requiring manual operation in real time, and they can also do some difficult outdoor work at the height, which considerably improves the comfort of the cleaning work. And in order to meet the requirements of outdoor work on the level, more and more attention is paid to the safety performance of the robot wiper system as well.Known robot wiper systems generally consist of a robot wiper and a base station. The robot wiper is provided with an adsorption mechanism. The adsorption mechanism is used to adsorb on a cleaning surface while the wiping robot operates, so that the wiping robot can clean the cleaning surface. The base station is provided with an adsorbing mechanism which adsorbs on a solid surface while the robot wiper operates. The base station is connected to the wiping robot via a safety cable.Normally, the robot wiper can be used for cleaning surfaces in the open air. Outdoor weather is an important factor affecting whether the robot wiper can safely operate outdoors. The wind is divided into 12 stages according to the up-site wind scale. The bed wind scale 4 has a wind speed of 5.5-7.9 m / s.The ability of the robot wiper to not fall to the ground and pose a risk with this level 4 wind is an important operating parameter for the robot wiper. In order to make the robot wiper resistant to wind force 4, one possibility is to increase the suction force of the adsorption mechanism. However, the higher the suction force of the adsorption mechanism, the higher the required output of the fan and the higher the weight of the fan. The higher the weight of the fan, the more there is a risk that the robot wiper falls down, so that the weight of the fan cannot be increased indefinitely. Another way to protect the robot wiper from the level 4 wind is to increase the base station traction force on the robot wiper so that in the event of the robot wiper falling the base station can immediately raise the robot wiper and pull it through the safety rope to prevent the robot wiper from falling on the ground, which could pose a risk. An increase in the pulling force of the base station on the robot wiper can be achieved by increasing the force of gravity of the base station. The greater the gravity of the base station, the greater the base station and the higher the cost, so that the gravity of the base station cannot be increased indefinitely. Another possibility for increasing the pulling force of the base station on the robot wiper is to increase the adsorption force of the adsorption device of the base station. The adsorption area of the adsorber is an important factor that influences the adsorption force of the adsorber. The larger the adsorption area of the adsorption device, the larger the adsorption force. Therefore, the adsorption surface of the adsorption device must not be too small, since otherwise it impairs the pulling force of the base station on the robot wiper.In the existing technology, it is usually necessary to operate a button on the base station to control the adsorption device to generate the adsorption force or release the adsorption force. The user causes the adsorption device to generate or release the adsorption force by pressing the button. According to the prior art, control of the adsorber via a key on the base station not only increases the cost of the base station, but also increases the size of the base station and makes the overall structure of the base station complex.In the prior art, the base station typically uses a motor to control the generation of negative pressure between the adsorption mechanism and the fixed surface, and the motor is turned on or off via the above-mentioned button to adsorb the base station on the fixed surface. When the robot wiper is subjected to an uncontrollable force such as wind or human pulling force on the surface to be cleaned, the adsorbing force between the adsorbing mechanism and the surface to be cleaned decreases. When this adsorption force is less than the gravity force of the robot wiper, the robot wiper drops down. Since the robot wiper and the base station are connected by a safety cable, the base station can lift the robot wiper in good time on the safety cable in the event of a fall, in order to prevent the robot wiper from falling to the ground and presenting a risk. However, this type of control of the motor via a key and the control of the adsorption device via the motor is complicated and very expensive.When an abnormal situation occurs in the operation of the robot wiper (e.g., when the robot wiper is stuck and cannot move, etc.) that cannot be handled safely, the risk of the robot wiper crashing and the safety of the robot wiper system being lowered increases.Note that the information disclosed in the above related art section is only for enhancing understanding of the background of the present disclosure, and therefore may include information not belonging to the related art known to those skilled in the art.DISCLOSURE OF THE INVENTIONAn aspect of the present application aims to solve the technical problem of how to improve safety of a robot wiper system, and how to realize adsorption and detachment between a base station for a robot wiper and a fixed surface, the structure of the base station for a robot wiper can be made simple, easy for the user to operate, with a small footprint, and stable and reliable accommodation between the base station and the fixed surface.Moreover, other aspects of the present application are also directed to solving or mitigating other technical problems of the prior art.The present application provides a base station for a robot wiper and a robot wiper system, in particular according to one aspect of the present application, to provide the following technical solutions:A robot wiper system, the robot wiper system comprising a base station for a robot wiper and a robot wiper, the base station for a robot wiper comprising: a base station body; an adsorber provided on the base station body, the adsorber comprising an adsorber, the adsorber comprising at least an adsorption state and a desorption state; a steering member provided on the base station body and capable of moving relative to the base station body, whereby the adsorber is switched between the adsorption state and the desorption state.

wherein the sweeping range of the first sweeping operation and the sweeping range of the second sweeping operation are continuous.According to another aspect of the present application, there is provided a base station for a robot wiper, comprising: a base station body; an adsorber provided on the base station body, the adsorber comprising an adsorber, the adsorber comprising at least an adsorption state and a desorption state; a steering member provided on the base station body and capable of moving relative to the base station body, whereby the adsorber is switched between the adsorption state and the desorption state, and wherein the adsorber has an area projected on the solid surface of not less than 156.9 square centimeters when in the adsorption state;The present application has the following advantageous effects: 1. the base station for a robot wiper of the present application comprises an adsorber and a steering member, and when the steering member is operated, the adsorber can be switched to the adsorption state and the desorption state to fix and release the base station relative to the solid surface; in this way, a purely mechanical coupling control is realized without requiring a complex structure with a motor or a solenoid valve, the control method is stable and reliable, and the structure of the base station is simple; Moreover, in the present application, the adsorption device is mechanically operated by means of the steering member, so that no additional button for controlling the switching device is required at the base station, so that on the one hand the costs due to the need for such a button are saved and on the other hand no additional space in the base station for the arrangement of the button needs to be taken up; since the steering member (handle) is already present in the base station, the structure of the base station is simpler and smaller. 2. the base station of the present application includes a switching device, an adsorbing device, and a steering member, and when the steering member is operated, it is possible to mechanically operate the switching device, close and open by the switching device, and then switch the adsorbing and desorbing state of the adsorbing device, and realize the attachment and detachment of the base station relative to the solid surface. In this way, a purely mechanical linkage control is realized without requiring a complex structure with a motor or an electromagnetic valve, the control method is stable and reliable, the structure of the base station is simple, and the present application mechanically operates the switching device by means of the steering member, so that it is not necessary to additionally set a switch control button at the base station, thus saving the cost resulting from the need for such a button. 3. the adsorbent body of the present application has an area of not less than 156.9 square centimeters projected onto a solid surface in the adsorption state, so that when the adsorbent body is adsorbed onto a solid surface having a gloss level of not less than 55°, the directing member is unable to switch the adsorber from the adsorption state to the desorption state with a vertical upward force of not more than 633.7N. Thereby, the base station can withstand the pulling force of the safety rope generated by the oscillation of the robot wiper in a wind of the step 4 while utilizing a small installation area. In addition, the area of the adsorbent is prevented from being increased to increase the adsorbing force between the base station and the fixed surface, which in turn increases the size of the base station; or to prevent the adsorbing force between the base station and the fixed surface from being insufficient to reduce the volume of the base station and to reduce the area of the adsorbent, which ensures stable and reliable adsorption between the base station and the fixed surface; and further reduces the risk of misoperation of the steering member by the user to cause the adsorbent to loosen the adsorption and further improves the stability of the attachment of the base station; 4. the switching of the adsorption and desorption state of the adsorption device may be controlled by the gravity of the handle, and when the user places the handle, the handle is automatically rotated from the second position to the first position by the gravity thereof, whereby the adsorption device is switched from the desorption state to the adsorption state. In this way, the adsorption device is switched from the desorption state to the adsorption state without the user having to put hand on his own, i.e. the operation by the user is reduced and the user is relieved, and when the user lifts the handle, the adsorption device is switched from the adsorption state to the desorption state, whereby the connection between the attachment of the base station and the use of the handle by the user is established. When the base station needs to be moved, it is not necessary for the user to perform further control of the base station in addition to raising the grip. When the robot wiper is stored in the base station and the user has to move the base station, the user has to perform two operations, one of which is to lift the lifting handle to a second position and the other of which is a desorption operation, such as manually pressing a desorption operation button of the suction cup, before the user can move the base station by lifting and pulling the lifting handle. The handle of the present application is configured such that, while the user raises and pulls the handle, the through hole of the adsorption cavity can be opened by the switching device, which in turn enables the adsorption device to be changed from the adsorption state to the desorption state. In other words, the user needs only one lifting operation to complete the two operations of desorption of the adsorber and lifting and pulling of the handle to hold the base station, which facilitates the operation for the user; moreover, the state of the adsorber can also be easily judged from the state of the handle, thereby more strongly associating the fixed state of the base station with its use. 5. the robot wiper system of the present application includes a base station for a robot wiper and a robot wiper, the robot wiper including a robot body and a vacuum source. The robot wiper system of the present application, when the adsorption device of the base station for a robot wiper is in an adsorption state, when the robot wiper moves on the surface to be wiped and an abnormal state occurs, performs an action to resolve the abnormal state, and the vacuum source continues to operate during the execution of the action so that the robot wiper does not leave the surface to be wiped. This improves the safety performance of the robot wiper system of the present application. In particular, when the robot wiper is cleaning the surface to be wiped, the adsorption device of the base station for robot wiper is normally in an adsorption state, so that the base station for robot wiper can be pulled by the safety rope on the robot wiper when the robot wiper falls in the event of a fall accident to prevent the robot wiper from falling further downward. However, when the robot wiper moves on the surface to be wiped to perform cleaning operations while the adsorption device of the base station for robot wiper is in the adsorption state, an abnormal state may occur. In particular, when there is no obstacle around the safety line connecting the robot wiper and the base station, so that the safety line can be freely drawn out or moved without being blocked or entangled by the obstacle, the robot wiper at a position away from the base station is liable to the above abnormality. For example, when the wiping robot is cleaning a large area of the surface to be wiped, the length of the safety rope connecting the wiping robot to the base station is pulled by the wiping robot more and more as the wiping robot moves more and more away from the base station; when the length of the safety rope protruding from the base station body reaches a maximum value of the length of the safety rope that can protrude from the base station body because the adsorber of the base station is in an adsorption state, when the wiping robot is then moved in the direction of pulling the safety rope, the pulling force of the safety rope tends to reach the abnormal state of the first threshold value, which in turn causes the safety rope to be in a tension state. On the other hand, when there are obstacles around the safety line connecting the robot wiper and the base station, the safety line is blocked or entangled by the obstacles and cannot freely extend or move. Specifically, when the length of the safety rope protruding from the base station body reaches a maximum value of the length of the safety rope that can protrude from the base station body, the safety rope is blocked or entangled by the obstacle and tends to be in a state of being tautly tensioned, so that the tensile force of the safety rope reaches a first threshold value. And when this abnormal state occurs, there is no safety accident, indicating the high safety performance of the robot wiper system. In the present application, the robot wiper performs an action to resolve the abnormality, and the vacuum source continues to operate during the execution of the action so that the robot wiper does not leave the surface to be wiped. In other words, the robot wiper is capable of completing the detachment of the abnormality on the wiping surface, so that the robot wiper does not drop when the abnormality is released. In other words, the present application improves the safety of the robot wiper system by preventing the robot wiper from dropping when the abnormality is resolved, by not leaving the surface to be wiped during the execution of the abnormality resolution action. Moreover, the window wiping robot is generally located at a higher position when an abnormality occurs. When the window wiping robot actively or passively leaves the surface to be wiped during execution of the abnormality-resolving action, the window wiping robot is very liable to fall from a higher position, resulting in damage to the window wiping robot and injury to the user or the object. 6.The robot wiper system of the present application has high safety performance. Specifically, as described above, the adsorption body of the base station of the robot wiper system of the present application has an area of at least 156.9 square centimeters projected onto a solid surface in the adsorption state; in this way, the base station of the robot wiper system of the present application is capable of withstanding the pulling force of the safety rope generated by the swing of the robot wiper at a step 4 storm to prevent the robot wiper from dropping to the ground and presenting a risk. On the other hand, when the robot wiper is in the adsorption state at the adsorption device of the base station for a robot wiper, when the robot wiper moves on the surface to be wiped and an abnormal state occurs, the robot wiper performs an action to release the abnormal state, and the vacuum source continues to operate during the execution of the action so that the robot wiper does not leave the surface to be wiped. In this way, fall during the resolution of the abnormality can be avoided. This improves the safety performance of the robot wiper system of the present application. 7. the robot wiper system of the present application has high cleaning performance. Specifically, the robot wiper has at least one continuation cleaning mode after interruption, and when the robot wiper performs the continuation cleaning mode, the robot wiper performs at least a first sweeping operation and a second sweeping operation on the surface to be wiped, and the sweeping range of the first sweeping operation and the sweeping range of the second sweeping operation are continuous, so that the robot wiper can clean the surface to be wiped in separate areas. In this way, if the performance of the robot wiper is insufficient, the area to be wiped can be cleaned zone by zone, thereby preventing the robot wiper from falling due to the insufficient performance, and after the performance is sufficient, the robot wiper can continue the operation before the insufficient performance to prevent repetition of wiping the area before the insufficient performance and improve the operation efficiency. And, when the surface to be wiped is soiled to improve the wiping effect, the surface in the cleaning sub-region may be wiped, and then the cleaning components may be replaced so that each region is clean cleaning components to improve the quality of the cleaning.ILLUSTRATION OF UTILITY MODELThese and other features of the present application will become apparent with reference to the accompanying drawings, which, as those skilled in the art will readily appreciate, are intended to be illustrative only and not to limit the scope of the present application.

Therefore, the following specific embodiments and the appended drawings are merely exemplary illustrations of the technical solutions of the present application, and should not be regarded as the entirety of the present application or as a limitation or limitation of the technical solutions of the present application.The orientation terms mentioned or possibly mentioned in the present specification, such as upper, lower, left, right, front, rear, front, rear, top, bottom, etc., are defined with reference to the constructions illustrated in the respective appended drawings which are relative terms and may therefore vary accordingly depending on the various positions in which they are located and the various states in which they are used. Therefore, these and other orientation terms should not be interpreted as limiting terms. Moreover, the terms "first", "second", "third", etc. or similar terms are used for descriptive and distinctive purposes only and are not to be understood as indicating or implying the relative meaning of the respective components or the order of assembly of the components.In a known robot wiper 900, the base station has, for example, a steering mechanism with a stepping motor and a push rod, the stepping motor controlling the push rod to open and close a valve opening of a valve body that controls the negative pressure of the suction cup of the base station, thus enabling the adsorption and detachment of the adsorption device. However, there is a risk that the push rod may be stuck during operation, and a switch is required to detect whether or not the push rod is in position. The structure of such a steering mechanism is relatively complex and requires the setting of an electronic program which cooperates in controlling the action of the stepping motor, and the stepping motor must be continuously supplied with power.In another known wiping robot 900, the switch of the valve opening is controlled, for example, by an electromagnetic valve which is directly connected to the suction device opening. In this solution, the solenoid valve must be energized for a long period of time (normally open solenoid valve) when the suction cup is sucked. If the solenoid valve is replaced with a normally closed solenoid valve, the suction cup remains sucked when the solenoid valve is not energized, and it is not possible to flexibly control the adsorption and detachment of the suction cup, which may result in a deteriorated user experience.The base station of the present application realizes a purely mechanical connection between the adsorber and the steering mechanism, which not only enables the adsorber to be immediately switched between the adsorption and desorption states, but also offers a simple and convenient control method; and due to the adsorption cavity in the present application in the adsorption state, the area projected on the solid surface is not less than 156.9 square centimeters. At the same time, the steering member cannot switch the adsorption device from the adsorption state to the desorption state under a vertical upward force of not more than 633.7N, so that the base station can take over the centrifugal force of a robot wiper 900 in the wind of the stage 4. At the same time, the adsorption cavity of the adsorption device does not require an excessively large installation area; moreover, the risk of the adsorption device being desorbed by the user's incorrect operation of the steering element is reduced.The robot wiper system of the present application includes: a base station for a robot wiper 10 and a robot wiper 900, the base station being used to be connected to the robot wiper 900 via a safety cable 800.As illustrated in FIG. 12, the base station body of the base station for a robot wiper 10 of the present application is connected to the robot wiper 900 via the safety cable 800. As illustrated in FIG. 13, the wiping robot 900 includes: a robot body; a cleaning component 901 provided in the robot body to clean the surface 2000 to be wiped; a driving component 902 provided in the robot body to drive the wiping robot to move on the surface 2000 to be wiped; a vacuum source provided in the robot body to adsorb the wiping robot 900 on the surface 2000 to be wiped.In an embodiment of the present application, a winding device is provided on the base station body, on which a safety rope 800 for connection to the host computer of the robot wiper 900 is wound. The safety line 800 is capable of applying a pulling force to the host computer when it is dropped from the work surface, so that the host computer does not drop directly to the ground, but floats in the air through the safety line 800 attached to the base station 10.In addition, the vacuum source includes a fan. A cavity is located on the underside of the robot body. The fan serves to suck air into the cavity when the robot wiper 900 is on the surface 2000 to be wiped, whereby the robot wiper 900 adsorbs to the surface 2000 to be wiped.The wiping robot 900 has at least one operating state in which the drive component 902 moves the wiping robot on the surface 2000 to be wiped, in order that the cleaning component 901 can perform cleaning tasks on the surface 2000 to be wiped. Of course, the wiping robot 900 is not limited to a working state, but may also assume other states, such as a non-working state in which the wiping robot 900 is adsorbed on the surface 2000 to be wiped and is stationary.As shown in FIG. 1, which shows a schematic diagram of the base station 10 according to an embodiment of the present application after the base station body has been removed. In Fig. 1, to better illustrate the devices for securing the base station 10, the base station body that could obscure the view of these devices is removed without touching the following description of the relative position of these devices with respect to the base station 10 or the base station body thereof.A person skilled in the art will be able to determine the corresponding positions of the other devices with respect to the base station body and the manner in which they are connected, on the basis of the following descriptions and how they are typically constructed.The base station 10 of the present application for a robot wiper 900 comprises:a base station body, a switching device 100, an adsorbing device 200, anda steering member 300. Herein, the base station body refers to a main body part other than the switching device 100, the adsorber 200, and the steering member 300 which are devices for fixing the base station body, as described below. The switching device 100, the adsorption device 200, and the routing member 300 are mounted on the base station body.The adsorption device 200 is located, for example, on the underside of the base station body in order to adsorb to a solid surface 1, which can be, for example, a floor, a window sill, a glass surface or the like. The adsorption device 200 is configured as, for example, a vacuum adsorption member such as a suction cup, a suction nozzle, etc., having at least an adsorption state and a desorption state. The adsorption state is adsorbed on the solid surface 1 by negative pressure in the adsorption state, so that an adsorption cavity not connected to the outside world is formed between the adsorber 200 and the solid surface 1; and the adsorption cavity is connected to the outside world in the desorption state to desorb the adsorption. Further, in an embodiment, as illustrated in FIG. 1, the adsorption device 200 includes an adsorption body 210 and a through hole 211 disposed on the adsorption body 210. In another embodiment, the adsorption device 200 comprises an adsorption body 210. The adsorbent body 210 is not disposed with the through hole 211. In the adsorption state, the adsorbent 210 is adsorbed to the solid surface 1 by negative pressure, and an adsorption cavity not connected to the outside world is formed between the adsorbent 210 and the solid surface 1; in the desorption state, the adsorption cavity is connected to the outside world to desorb.In the embodiment of FIG. 1, the adsorption device 200 is configured as, for example, a vacuum adsorption member such as a suction cup or a suction nozzle, and the adsorption device 200 includes an adsorption body 210 and a through hole 211 disposed on the adsorption body 210 and connected to the adsorption cavity of the adsorption body 210. When the base station 10 is placed on the solid surface 1, the base station 10 first presses the adsorbent body 210 against the solid surface 1 due to its own gravity, whereby the adsorption cavity of the adsorbent body 210 forms a vacuum adsorption cavity. At this time, in the adsorption state, the switching device 100 closes the through hole 211 so that an adsorption cavity not connected to the outside world is formed between the adsorption body 210 and the solid surface 1, and the adsorption device 200 is adsorbed on the solid surface 1. When the switching device 100 opens the through hole 211 in the desorption state, the adsorption cavity is connected to the outside through the through hole 211, and the adsorption device 200 is not adsorbed on the solid surface 1.It will be understood that the "adsorption cavity" described in the present application comprises a vacuum, near vacuum or space having at least a negative pressure lower than the normal atmospheric pressure prevailing between the adsorbent body 210 and the solid surface 1. Since the space has a negative pressure lower than the normal atmospheric pressure, when the space is not connected to the outside world, the atmospheric pressure presses the adsorbent body 210 onto the solid surface 1 to achieve the effect of adsorption and fixation.Further, in the adsorption state of the adsorption device 200, when the robot wiper 900 moves on the surface to be wiped 2000 and an abnormal state occurs, the robot wiper 900 performs an action to release the abnormal state, and the vacuum source continues to operate during the execution of the action so that the robot wiper 900 does not leave the surface to be wiped 2000.Further, in the operating state of the robot wiper 900, the adsorption device 200 is normally in the adsorption state. While the robot wiper 900 is in the working state, the robot wiper 900 is liable to be in an abnormal state. The abnormal state includes a state in which the robot wiper 900 is stuck and remains on the surface 2000 to be wiped when the cleaning task is not completed. The dead reckoning includes a situation where the safety line 800 pulls on the wiping robot 900 when the safety line 800 is in a tensioned state, thereby preventing the wiping robot 900 from moving further. The tension state includes a situation in which the length of the safety rope 800 protruding from the base station body reaches a maximum value of the length of the safety rope 800 that can protrude from the base station body, and the tension reaches a first threshold value. In particular, the safety rope 800 is in the tensioned state when the tensile force of the safety rope 800 reaches the first threshold value. For example, as illustrated in FIG. 12, when there is no obstacle around the safety cable 800 connecting the robot wiper 900 and the base station 10, so that the safety cable 800 can be freely drawn out or moved without being blocked or entangled by the obstacle, the robot wiper 900 is vulnerable to the above abnormality at a position away from the base station. For example, when the wiping robot 900 is cleaning a large area of the surface 2000 to be wiped, due to the fact that it moves farther and farther away from the base station 10, the wiping robot 900 moves farther and farther away from the base station 10 as the wiping robot 900 moves away from the base station 10 toward the surface 2000 to be wiped side (e.g., as shown in FIG. 12, where the wiping robot 900 moves rightward from the point B); thus, the length of the safety rope 800 connecting the wiping robot 900 to the base station 10 is pulled longer and longer by the wiping robot 900, i.e., the safety rope 800 is detached from the winder and extends outward. When the length of the safety rope 800 protruding from the base station body reaches the maximum value of the length of the safety rope 800 that can protrude from the base station body (e.g., as shown in FIG. 12, where the wiping robot 900 moves from point B to point A to the right), the adsorption device of the base station 10 is in an adsorption state due to the adsorption device of the base station 10; when the wiping robot 900 then moves in the direction in which it pulls on the safety rope 800 (e.g., to the right as shown in FIG. 12 ), the pulling force of the safety rope 800 tends to reach an abnormal state of the first threshold value, which in turn causes the safety rope 800 to be in a tensioned state. The first threshold may be a value of the tensile force that places the safety rope in a tensioned state.The robot wiper 900 performs the action of resolving the abnormal state and does not leave the surface 2000 to be wiped during the execution of the action. In this way, the present application improves the safety of the robot wiper system by not leaving the surface to be wiped during the execution of the abnormal condition release action, so that the robot wiper is not subjected to a crash upon cancelling the abnormal condition. Specifically, the rotation speed of the fan is kept constant or increased during execution of the abnormal condition releasing action by the robot wiper 900, so that the robot wiper 900 does not leave the surface 2000 to be wiped.Further, the wiping robot 900 performs the abnormal state release action by receiving a remote control signal and then performing a moving action to cancel the abnormality. Specifically, the robot wiper 900 may be caused to move by operating a remote control button of an application installed on a mobile device (e.g., a mobile phone). The application may be, for example, an app communicatively connected to the robot wiper 900. Of course, the robot wiper 900 may also be actuated by the operation of a remote control communicatively connected to the robot wiper. For example, as illustrated in FIG. 12, when the robot wiper 900 is located at point A, the robot wiper 900 may be moved by remotely controlling the robot wiper 900 such that the robot wiper 900 moves toward point B on the surface 200 to be wiped, thereby releasing the tension of the safety rope 800, which also means that the safety rope is in a naturally slack state and greatly reducing the pulling force of the safety rope.Further, the wiping robot 900 performs an action to release the abnormal state, for example, by raising and pulling the steering member so that the adsorption body is in the non-attached state, thereby releasing the tensioned state of the safety rope 800.Further, the robot wiper 900 is in an operating state in which the robot wiper 900 is in at least a stop renewal cleaning mode. When the wiping robot 900 executes the continuation cleaning mode after interruption, the wiping robot 900 performs at least a first sweeping operation and a second sweeping operation on the surface 2000 to be wiped, the sweeping range of the first sweeping operation and the sweeping range of the second sweeping operation being continuous.In particular, the sweeping range of the first sweeping operation and the sweeping range of the second sweeping operation are continuously defined, since the first sweeping operation and the second sweeping operation follow one another in the working range and the sweeping range of the first sweeping operation and the sweeping range of the second sweeping operation partially overlap. For example, the cleaning region of the first cleaning operation is an upper part of the surface 2000 to be wiped. The sweeping range of the second sweeping operation is a lower part of the surface 2000 to be swept. The end of the sweeping range of the first sweeping action and the head of the sweeping range of the second sweeping action overlap. In particular, the working range of the first sweeping operation and / or of the second sweeping operation can be determined on the basis of the operating time of the wiping robot. As illustrated in FIG. 12, the region to be cleaned of the surface 2000 to be wiped is divided into, for example, a first sweeping region between B→A→D in which the travel time of the robot wiper is 5 minutes and a second sweeping region between D→C→E remaining on the surface to be wiped; in this working region, the operation time of the robot wiper is 6 minutes. These at least two working areas facing one another include the working area between B→A→D and the working area between D→C→E. Of course, the area to be cleaned of the surface 2000 to be wiped is not limited to the two working areas described above, but can also be divided in another manner. For example, the region to be cleaned of the surface 2000 to be wiped is divided into a working region in which the operating time of the robot wiper is 4 minutes and a working region in which the operating time is 7 minutes. Alternatively, the region to be cleaned of the surface to be wiped is divided into a working region in which the operation time of the robot wiper is 8 minutes, a working region in which it operates for 1 minute, and a working region in which it operates for 2 minutes. This is not intended in the present application. The sweeping range of the first sweeping operation and the sweeping range of the second sweeping operation partially overlap. That is, there is an overlap between the working range between B→A→D and the working range between D→C→E. For example, the working range between B→A→D and the working range between D→C→E may overlap around the point D to prevent a leak of wiping between the working range between B→A→D and the working range between D→C→E.Further, the robot wiper 900 has other cleaning modes such as a rim cleaning mode, an overall cleaning mode, and the like, and no details are given in the present application. The cleaning mode along the edge may be that the wiping robot 900 moves along an edge of the surface 2000 to be wiped to clean the edge of the surface 2000 to be wiped. The overall cleaning mode may consist in the wiping robot 900 traversing the surface 2000 to be wiped in order to clean all regions of the surface 2000 to be wiped.In an embodiment of the present application, the adsorbent body 210 in the adsorption state projects onto the solid surface 1 with a projected area of at least 156.9 square centimeters, so that when the adsorbent body 210 is adsorbed on the solid surface 1 with a gloss level of at least 55°, the steering member 300 is unable to bring the adsorber 200 from the adsorption state to the desorption state with a vertically upward force of not more than 633.7N.The base station 10 of the robot wiper 900 is used for the adsorption on the solid surface 1. The solid surface may be a floor in a house. Of course, the solid surface is not limited to being a floor inside the house, but may be a floor outside the house. In addition, the floor in the house is generally a surface of tiles, floor coverings, cement and the like. The tiles also include glossy tiles, soft tiles and matt tiles. The glossy tiles have a gloss level of more than 55° and the soft tiles have a gloss level of more than 25° and not less than 55°. The matt tile has a degree of gloss of less than 15°. In this way, the difference in material between the individual solid surfaces can be differentiated on the basis of the degree of gloss. In addition, the adsorbent body of the present application is adsorbed on the solid surface 1 with a gloss level of not less than 55°. For example, the adsorbent body of the present application is adsorbed on soft tiles having a gloss level of not less than 55°. Of course, the adsorbent body of the present application is not limited to adsorption on soft tiles having a gloss level of at least 55°, but may be adsorbed on other materials, for example, the adsorbent body of the present application is adsorbed on a floor having a gloss level of at least 55°, or the adsorbent body of the present application is adsorbed on glossy tiles having a gloss level of at least 55°.For the wiping robot 900, the narrow edge of the window to be wiped is, for example, generally not less than 20 mm, so that the outer edge length of the square wiping robot 900 is generally at most 20 mm and the weight of the wiping robot 900 is generally at most 2 kg on account of this dimension limitation.When attached to the glass, particularly outdoors, the robot wiper 900 may easily fall off the glass when exposed to uncontrollable forces such as wind outdoors. Since the robot wiper 900 is connected to the base station 10 via a safety line 800, after the robot wiper 900 has fallen off the window, the base station 10 can apply a pulling force to the robot wiper 900 in time via the safety line 800 to prevent the robot wiper 900 from falling on the ground, which might pose a risk. The greater the tensile force exerted by the base station 10 on the wiping robot 900 via the safety cable 800, the better the wiping robot 900 can operate even in the case of stronger wind. Namely, even if the robot wiper 900 falls due to wind, the base station 10 can immediately pull the robot wiper 900 on the safety rope 800 without falling to the ground.However, when the wind intensity reaches level 4 outside, the robot wiper 900 may swing outside under the force of the wind when dropping and being pulled by the safety rope 800. And, when the robot wiper 900 is pulled by the safety rope 800 and swings outward, it is subjected to the action of the centrifugal force and its own gravity. Since the robot wiper 900 is connected to the base station 10 via the safety cable 800, the centrifugal force and the gravity are finally transmitted to the base station 10 via the safety cable 800. That is, when the safety rope 800 is pulled by the centrifugal force and the gravity from the robot wiper 900, the base station 10 is pulled by the same force from the safety rope 800, and also the safety rope 800 is pulled by the same force from the base station 10.Due to the centrifugal force F=mv 2 / r, the smaller the swing radius of the robot wiper 900 that vibrates in the wind, the greater the centrifugal force F. In addition, the minimum swing radius for the robot wiper 900 oscillating under the wind force is not less than the length of a robot wiper body 900, so that, when the length of a robot wiper body 900 is the swing radius, the maximum centrifugal force at which the robot wiper 900 oscillates is 2 / 0.2=624.1 N under the wind force of a strength of Stage 4 wind strengths (a strength of four wind strengths at a wind speed of 5.5 to 7.9 m / s) 2kg* (7.9 m / s). And the gravity G=mg, i.e. the gravity G of the robot wiper 900 is 2kg*9.8m / s=19,6N, so that the sum of the centrifugal force and the gravity of the robot wiper 900 is 624.1+19.6=633.7N at the maximum in a stage 4 storm. Thus, when the robot wiper 900 falls on a step 4 storm and is pulled by the safety rope 800 and swings, the force that the robot wiper 900 applies to the base station 10 through the safety rope 800 is 633.7N at the maximum.When the force that the robot wiper 900 applies to the base station 10 via the safety line 800 reaches 633.7N in a level 4 wind, the base station 10 and the adsorber must apply a pulling force of 633.7N to the safety line 800 to ensure that the robot wiper 900 does not fall on the ground. And, when the base station 10 and the adsorber are required to exert a pulling force of 633.7 N on the safety rope 800, the suction force of the adsorber is required to reach 633.7 N when the weight of the base station 10 itself is not taken into consideration (ideally). The formula for calculating the suction force of the adsorption device is: suction force=S*P / μ. Where: S is the area of the suction cup (cm 2), P is the air pressure (kg / cm 2) and μ is a safety factor >=2.5. In the present application, S is the surface of the adsorbent body in the adsorption state projected on the solid surface 1 (cm 2), and P is 1 atmospheric pressure (1.01×10 5 N / m 2). 1 Standard atmospheric pressure=1.01×10 5 Pa=1.01×10 5 N / m 2. If the suction force of the adsorption device 633.7 must reach N, μ assumes the minimum value of 2.5, then according to the formula S= Saug force*μ / P, the minimum of S in the ideal state P is s=633.7N*2.5 / 1.01×10 5 N / m 2 ≈0.015686m 2 ≈156.9cm 2. That is, the minimum area of the adsorbent body in the state of adsorption projected on the solid surface 1 is 156.9 cm 2. in the ideal state.Therefore, the adsorption device 200 of the present application cannot switch from the adsorption state to the desorption state in the adsorption state when the projected area on the solid surface 1 is not less than 156.9 square centimeters, the adsorbent body having a gloss level of not less than 55° is adsorbed on the solid surface 1, and the steering member is subjected to a vertically upward force of not more than 633.7N. In this way, when the robot wiper 900 is subjected to the centrifugal force caused by a force under the wind of the stage 4 and thus exerts a large tensile force (633.7N) on the base station 10, the base station 10 can still be well fixed to the solid surface 1 by the adsorption of the adsorbent body 210, i.e., the base station 10 can be pulled by the safety rope 800 by the main robot wiper 900 without dropping to the ground. This is because the base station 10 can withstand a maximum tensile force of 633.7N when the adsorbent body is adsorbed on the solid surface with a gloss level of at least 55°. On the other hand, while the base station 10 can withstand the maximum pulling force of 633.7 N, the area of the adsorbent 210 can be kept small, thereby preventing inconveniences for the user due to the increase in the installation area of the adsorbent 210 for increasing the adsorbing force, and the base station 10 can also be kept small in size and weight.Moreover, since the steering member 300 is unable to transfer the adsorption device 200 from the adsorption state to the desorption state under a vertical upward force of at most 633.7 N, user's abuse of the steering member 300 is also prevented. The tensile force of an adult is generally 38 kg, which corresponds to a force of approximately 380 N. Therefore, in the state where the adsorption body 210 in the present embodiment is adsorbed on a solid surface, the pulling force of an adult cannot pull on the base station. Thereby, unnecessary detachment of the adsorption apparatus 200 by arbitrarily pulling the steering member 300 or the base station 10 itself by the user is avoided.The steering member 300 is capable of moving relative to the base station body to mechanically operate the switching device 100 that opens or closes the above-described through hole 211 via the switching device 100, whereby the adsorption apparatus 200 can switch between the adsorption state and the desorption state. For example, the steering member 300 may rotate relative to the base station body to open or close the through hole 211 through the switching device 100, thereby allowing the adsorption device 200 to switch between the adsorption state and the desorption state; or the steering member 300 is capable of sliding relative to the base station body or moving to open or close the through hole 211 through the switching device 100, thereby enabling the adsorption device 200 to switch between the adsorption state and the desorption state. In an embodiment of the present application, the base station body floats down by less than 2 mm when the adsorber 200 is switched from the desorption state to the adsorption state. Thereby, the base station body can be kept stable when the adsorber 200 is switched between the desorption state and the adsorption state, thereby preventing excessive shaking of the base station body to prevent poor current contact or changes in the pulling force of the safety wire 800 on the robot wiper 900, which in turn can result in dropping of the robot wiper 900. When the wiping robot 900 is in operation, the adsorption device 200 is in the adsorption state, and when the user, e.g., a child, repeatedly randomly reciprocates the steering member 300, this may cause the base station body to continuously switch between the desorption and adsorption states, which may cause the base station body to shake up and down. The robot wiper 900 is connected to the base station body via the safety cable. When the amplitude of the oscillation of the base station body is large, the pulling force of the safety rope 800 on the robot wiper 900 also increases, which may result in the robot wiper 900 falling, which may be dangerous, or may result in poor contact with the power supply, which in turn may result in sudden power failure of the robot wiper 900, which may also result in the robot wiper 900 falling down. By limiting the vertical displacement of the base station body when the state of the adsorber 200 is changed, particularly by limiting to 2 mm, the stability of the base station body during attachment and detachment is improved and the above risk is avoided.In an embodiment of the present application, such as the embodiment of FIG. 1, the steering member 300 is provided as a handle with which a user can manipulate the adsorption state of the adsorption device 200 and also raise or support the base station 10 by means of the handle, thereby changing the position of the base station 10. In the case where the steering member 300 is formed as a grip, the grip has a first state and a second state when the adsorbent is in contact with the fixed surface 1 after the base station 10 is placed on the fixed surface 1. In the first state, the handle is in the lowest reachable position defined as the first position, and in the second state, the handle is in a position different from the first position. In an embodiment of the present application, in the second state, the handle is in a position different from the first position, the other position comprising the second position, and in the second position, the handle is in the highest accessible position.As shown in Figures 2 to 3, there is a side view and a top view, respectively, of a base station 10 with the base station body removed, as shown in Figure 1, with the handle in the second position. The second position may be described as a raised state of the handle. In this second position, the handle is directed upward so that the switching device 100 opens the through hole 211 to put the adsorption device 200 in an unfixed state. In the second position, the user can directly pull the handle with hand to cancel or drop the base station 10 and thus change the position of the base station. As shown in Figures 4 and 5, there are shown a side view and a top view, respectively, of the base station 10 with the base station body removed according to Figure 1 with the handle in the first position. The first state may also be described as a lowered state of the handle in which the handle is at the lowest accessible position, i.e., the first position, such that the switching device 100 closes the through hole 211 to put the adsorption device 200 in the adsorption state. That is, the adsorption device is in the adsorption state when the steering member naturally falls to its lowermost position. In an embodiment of the present application, the handle is automatically switched from the second position to the first position by gravity, thereby establishing the adsorption state between the adsorber 200 and the solid surface 1. With this embodiment, it is achieved that the operation of the adsorber 200 is automatically performed by the gravity of the handle when the user's hand is released from the handle, so that the operation of switching the adsorber from the desorption state to the adsorption state does not require practical operation by the user, i.e., the operation by the user is reduced and convenient for the user. In particular, the handle can consist of individual connecting sections. The individual connecting portions are connected to each other to form the handle. The individual connecting portions can be connecting rods, for example. Of course, the connecting portions are not limited to connecting rods, but may be other structures such as connecting plates, connecting straps, etc., for which the present application does not contain any regulations. In addition, the tie rods may be connected vertically, at an angle, or transversely, which is not provided in the present application. The plane in which the center lines of the respective connecting portions of the handle are located is the plane in which the handle is located. In one embodiment, the plane in which the handle is located in the second position may be a plane perpendicular to the solid surface 1. In another embodiment, the plane in which the handle is located in the second position is a plane forming an angle to the solid surface 1. In one embodiment,Figures 6 and 7 are a side view and a top view of the handle in the second position with respect to the fixed surface 1. As shown in FIG. 6, the steering member 300 is comprised of a handle having a horizontal extension portion 320, and a first vertical extension portion 310, and a second vertical extension portion 330, which are connected to the ends of the horizontal extension portion 320, respectively. As illustrated in FIG. 6, the center line L 2 of the horizontal extension portion 320, the center line L 1 of the first vertical extension portion 310, and the center line L 3 of the second vertical extension portion 330 lie in one plane, and the plane in which the center line L 2 of the horizontal extension portion 320, the center line L 1 of the first vertical extension portion 310, and the center line L 3 of the second vertical extension portion 330 lie is the plane in which the handle is located, which is perpendicular to the fixed surface 1. As illustrated in FIG. 7, the center line L 2 of the horizontal extension portion 320 is parallel to the fixed surface 1, and in plan view, the horizontal extension portion 320 shades the first vertical extension portion 310 and the second vertical extension portion 330. Comparing FIGS. 6 and 7, it will be more apparent that in one embodiment, in the second position, the horizontal extension portion 320 is disposed over the first vertical extension portion 310 and the second vertical extension portion 330 and the plane in which the entire handle is located is perpendicular to the fixed surface 1.In an embodiment of the present application, the height of the lowest point of the handle is at least half the height of the base station body when the handle is in the first position. The "lowest point of the handle" is understood to mean the lowest position of the connecting portions of the handle in the direction of gravity. This arrangement takes into account the user's ergonomy when using the handle. When the handle is in the first position, the lowest point of the handle has a certain height position (the lowest point of the handle is not lower than half the height of the base station main body) to facilitate the user's hand gripping and avoid the user having to bend or honk when raising the handle in the first position because he has to grip down to the lower part of the base station body for raising and to further facilitate the user's operation of the handle.In an embodiment of the present application, the base station body is provided with a trigger portion, and in the second state, the handle is in a position different from the first position, and the other position also includes a third position different from the second position. After the grip is switched from the third position to the first position by the operation of a user, the trigger portion triggers to notify the user that a negative pressure adsorption state has occurred between the adsorbent body 210 and the solid surface 1. The trigger portion, which is not shown in the attached drawings, may be provided on the handle or the base station body, for example, is triggered by the state of movement of the handle relative to the base station body or by the handle entering the first position, and is set to alert the user by a pattern, a color, a sound, or a feeling in hand. In this way, the user can timely recognize that the base station 10 is fixed to the fixed surface 1 by the adsorbent 210 at this time. In a merely exemplary embodiment, the trigger portion is provided, for example, on a rotational connection between the handle and the base station body, which comprises a hole worked into the handle and a display pattern, for example a red display pattern, on the base station body, which is visible through the hole in the first position. When the handle is in the third position, the display pattern is not visible through the hole, and when the handle is switched from the third position to the first position, the display pattern is visible through the hole in the handle, alerting the user that the handle is in the first position at that time, i.e., that the base station 10 has been attached by the adsorber 200.In an embodiment of the present application, for example, in the embodiment of FIG. 1, the steering member 300 is connected to the shifting device 100 via a transmission mechanism 400. The transmission mechanism 400 is a three-link mechanism in FIG. 1, including a first link 410, a second link 420, and a third link 430 that are sequentially linked along the gravity direction, the end of the first link 410 behind the second link 420 is connected to the steering member 300 and the end of the third link 430 behind the second link 420 is connected to the shifting device 100. The transmission mechanism 400 is used to transmit the rotational movement of the steering member 300 to the switching device 100 to allow the switching device 100 to close or open the above through hole 211. It is understood that the transmission mechanism 400 may also be configured as other transmission mechanisms, such as a gear transmission mechanism, a belt transmission mechanism, a chain transmission mechanism, and the like. The arrangement of the transmission mechanism 400 provides a variety of position possibilities for the arrangement of the steering member 300 on the base station body, and by means of the transmission mechanism 400, it is possible to adjust the ratio of the motion transmission between the steering member 300 and the switching device 100. The transmission mechanism 400 has an input end connected to the steering member 300 and an output end connected to the shifting device 100. In an embodiment, the projection of the switching device 100 and the transmission mechanism 400 onto the front side of the base station body at least partially and / or the projection of the switching device 100 and the transmission mechanism 400 onto the side of the base station body at least partially and / or the projection of the switching device 100 and the transmission mechanism 400 onto the bottom surface of the base station body at least partially overlap.In an embodiment of the present application, the steering member 300 may also be directly connected to the shifting device 100 without a transmission mechanism interposed therebetween, so that a rotational movement of the steering member 300 is directly converted into a movement of a component in the shifting device 100. The present embodiment can be applied not only to technical solutions including a transmission mechanism 400 but also to technical solutions including no transmission mechanism 400, which will not be described in detail in the description of the present embodiment.In an embodiment of the present application, the switching device 100 comprises a first valve element connected to the adsorption body 210 and a second valve element connected to the steering element 300, wherein an opening 111 is provided in the first valve element, wherein the opening 111 is connected to the through hole 211, and wherein a rotation of the steering element 300 causes a rotation of the second valve element with respect to the first valve element to open and close the opening 111. When the opening 111 is opened, the through hole 211 is connected to the outside world through the opening 111. At this time, the adsorption cavity is also connected to the outside world, and the adsorber 200 is desorbed. When the opening 111 is closed, both the through hole 211 and the adsorption cavity are closed to the outside world, and the adsorption device 200 is adsorbed. As illustrated in FIG. 8, the schematic structure of the switching device 100 of the present embodiment is shown. In the embodiment of FIG. 8, the first valve element is a valve body 110 and the second valve element is a valve core 120 that has at least partially penetrated into the valve body 110, the valve core 120 being capable of rotating relative to the valve body 110. The valve body 110 includes, for example, a first valve body portion 101 parallel to the fixed surface 1 and a second valve body portion 102 perpendicular to the fixed surface 1, the valve core 120 is screwed into the first valve body portion 101, and the valve body 110 is connected to the adsorbent body 210 via the second valve body portion 102. In embodiments having a transmission mechanism 400 between the steering member 300 and the shifting device 100, a third connecting rod 430 of the transmission mechanism 400 is connected to the valve core 120 at an end rearward of the second connecting rod 420. In embodiments where there is no transmission mechanism 400 between the steering member 300 and the shifting device 100, the steering member 300 is directly connected to the valve core 120. In embodiments not shown, the second valve element can also be designed as a valve body and the first valve element as a valve core which is at least partially screwed into the valve body, wherein the valve core can rotate with respect to the valve body. This construction can also apply to the following embodiments accordingly.In an embodiment of the present application, the valve body 110 is provided with a first passage 112 therethrough, and the valve core 120 is provided with a second passage 122 communicating with the first passage 112, the second passage 122 having an open end 1221 at one end and a closed end 1222 at the other end. That is, the valve body 110 and the valve core 120 have, for example, the shape of a hollow column, and their hollows are connected to each other. In the embodiment of FIG. 8, the valve core 120 is inserted into the valve body 110, e.g., through the open end 1221 of the second passage 122, such that the second passage 122 communicates with the first passage 112, in particular in hermetically sealed communication with the external atmosphere.Further, in an embodiment of the present application, particularly in the embodiment of FIG. 8, the opening 111 is provided in a side wall of the valve body 110. As illustrated in FIG. 8, the first valve body portion 101 is provided, at an end opposite to the second valve body portion 102, with a port through which the valve core 120 is screwed into the first valve body portion 101. The opening 111 is located in the port. A gas outlet opening 121 is located on a side wall of the valve core 120. When the valve core 120 is rotated relative to the valve body 110, the gas outlet port 121 is connected to or displaced from the port 111 to open or close the port 111. When the gas outlet port 121 is connected to the opening 111, the through hole 211 is connected to the external atmosphere via the opening 111 and the gas outlet port 121, and when the gas outlet port 121 is not aligned with the opening 111, the through hole 211 is connected to the closed space formed by the first passage 112 and the second passage 122, but is sealed from the external atmosphere.In another embodiment of the present application, as shown in FIG. 9, there is seen a partial structure diagram of a switching device of this embodiment. In this embodiment, the valve body 110 is also configured as an internally hollow tubular body. One end thereof is connected to a through hole 211 (not shown in FIG. 9 ) that can be connected to the through hole 211 of the adsorbent body 210 via a connection pipe, for example, and the other end thereof or near the other end thereof is provided with a paired end surface 113 in the tubular body. The valve core 120 has at least one end surface 123 and a side wall 128 surrounding this end surface 123 and connected to, for example, the side wall 128 of the valve core 120 which can be connected to the steering member 300 or the transmission mechanism 400 via a connecting member 129, and a gas outlet port 121 is provided in the end surface 123 of the valve core 120. In the side wall 128 of the valve core 120, an outwardly open flow channel is formed. The flow channel is connected to the gas outlet port 121, so that the gas outlet port 121 can be connected to the outside world via the flow channel. The valve core is inserted into the valve body 110 with an end surface 123 abutting against a paired end surface 113. In the paired end surface 113 of the valve body 110, an opening 111 (not illustrated in FIG. 9 and illustrated in FIG. 10 ) is provided. When the valve core 120 is rotated relative to the valve body 110, the gas outlet port 121 communicates with or is offset from the port 111 to open or close the port 111. For example, either the opening 111 or the gas outlet opening 121 may be distributed as one or more openings radially along the end surface, as illustrated in FIG. 10, which shows a comparative view of the opening 111 of the valve body 110 and the gas outlet opening 121 of the valve core 120 of the switching device 100 illustrated in FIG. 9. In FIG. 10, both the opening 111 and the gas outlet opening 121 are shown as two holes distributed in the radial direction, which can be connected or adjusted by rotation. Of course, the opening 111 and the gas outlet opening 121 may also have other shapes or positions, etc., which can be connected or adjusted with each other upon relative rotation.In an embodiment of the present application, the switching device 100 includes a first valve element connected to the adsorption body 210 and a second valve element connected to the steering member 300, wherein the opening 111 is provided in the first valve element, the opening 111 is connected to the through hole 211, and rotation of the steering member 300 causes the second valve element along a straight line with respect to the first valve element to open and close the opening 111. It is to be understood that "the second valve element moves in a straight line relative to the first valve element" is to be understood that the second valve element has a degree of freedom to move in a straight line relative to the first valve element, and not only means that the second valve element moves only in a straight line relative to the first valve element. For example, it is also possible that the second valve element rotates relative to the first valve element while moving in a straight line relative to the first valve element.In an embodiment of the present application, the first valve element is a valve body 110 and the second valve element is a valve core 120 at least partially screwed into the valve body 110, wherein the valve core 120 can move in a straight line relative to the valve body 110. In embodiments not shown, the second valve element can also be designed as a valve body and the first valve element as a valve core which is arranged at least partially in the valve body, wherein the valve core can rotate relative to the valve body. This construction can also apply to the following embodiments accordingly.Further, in an embodiment of the present application, a first passage 112 is provided through the valve body 110, the first passage 112 having both a first end portion and a second end portion with open ends, and the valve core 120 is at least partially disposed through the first passage 112.Further, in an embodiment of the present application, as illustrated in FIG. 11, a schematic diagram showing the structure of the switching device 100 according to this embodiment is provided. A helical groove 114 (shown by a broken line in FIG. 11 ) is provided on a side wall of the valve body 110, and a protrusion portion 124 that fits into the helical groove 114 is provided on a side wall of the valve core 120. When the valve core 120 is rotated by the steering member 300, the protrusion portion 124 moves along the spiral groove 114, whereby the valve core 120 is moved in a straight line relative to the valve body 110. In this embodiment, the cooperation between the spiral groove 114 and the protrusion portion 124 is similar to the transmission principle of a worm gear that achieves the conversion from a rotational movement to a linear movement, thereby converting a rotation of the valve core 120 relative to the valve body 110 to a linear movement of the valve core 120 relative to the valve body 110. In a first embodiment of the present application, the helical groove 114 may also be provided on the outer wall of the spool 120, the protruding part 124 being correspondingly provided on the inner wall of the valve body 110, and this type of construction may also be applied to the embodiment described below.In a first embodiment of the present application, the protrusion portion 124 is provided to surround the side wall and sealingly engage with the helical groove 114, which serves to be able to isolate the passage. For example, in the embodiment of FIG. 11, the opening 111 is formed by the first end portion of the first passage 112, the gas outlet opening 121 is provided on the side wall of the valve body 110, and one end of the valve core 120 is capable of closing the opening 111 in the direction of linear movement. In this embodiment, both the opening 111 and the gas outlet opening 121 are disposed above the valve body 110, the opening 111 is formed by a first end portion of the first passage 112 connected to the through hole 211, and is closed when the first end portion is closed by one end of the valve core 120, particularly when the valve core 120 is inserted into the first end portion by a linear movement, and is opened when the valve core 120 does not close the first end portion, particularly when the valve core 120 is not inserted into the first end portion. In the embodiment of FIG. 11, the gas outlet port 121 is provided on a side wall of the valve body 110, and when the port 111 is opened, the passage from the port 111 to the gas outlet port 121 is also opened.In a second embodiment of the present application, the protrusion portion 124 is provided so as to surround the side wall and sealingly engage with the spiral groove 114, the diameter of the first end portion of the first passage 112 is smaller than the diameter of the second end portion, the opening 111 is formed by the first end portion of the first passage 112, and the gas discharge opening 121 is formed by the gap between the second end portion and the valve core 120. One end of the valve core 120 is capable of closing the opening 111 in the direction of linear movement. In this embodiment, for example, the first passage 112 includes three portions, namely, a first portion 1121 having a smaller diameter, a second portion 1122 having a larger diameter, and a connecting portion 1123 connecting the first portion 1121 and the second portion 1122 to each other. The first end portion is formed at a free end of the first portion 1121, and the second end portion is formed at a free end of the second portion 1122. One end of the valve core 120 may be inserted into the first portion 1121 to close the first end portion, i.e., to close the opening 111. And due to the larger diameter of the second portion 1122, an annular gap is formed between it and the valve core 120, which then forms the gas outlet opening 121. When the valve core 120 does not close the opening 111 by a linear movement, the passage between the opening 111 and the gas outlet opening 121 is opened. The passage from the opening 111 to the gas outlet port 121 is closed when the protrusion portion 124 fits into the spiral groove 114, and the passage from the opening 111 to the gas outlet port 121 is opened when the protrusion portion 124 moves out of the spiral groove 114. In this embodiment, the protrusion portion 124 and the spiral groove 114 not only function as a transmission, but also close the communication passage between the opening 111 and the gas outlet opening 121. At this time, the opening 111 and the gas outlet opening 121 are located at both ends of the valve body 110. When the valve core 120 is connected to the valve body 110 via the protrusion portion 124 and the spiral groove 114, the passage between the opening 111 and the gas outlet opening 121 is closed by the protrusion portion 124, and when the protrusion portion 124 is turned out of the spiral groove 114, the passage between the opening 111 and the gas outlet opening 121 is opened.In a third embodiment of the present application, for example, the protrusion portion 124 is provided as a mere protrusion on the side wall of the valve core 120 having a gap to the side wall of the valve body 110, or is provided such that when the valve core 120 and the valve body 110 are assembled by the protrusion portion 124 and the spiral groove 114, a gap in the radial direction is always present between the valve body 110 and the valve core 120 at the assembly location. At this point, the projection portion 124 and the spiral groove 114 serve only for operation and not for sealing. The protrusion portion 124 may be provided as a protrusion at a radial position on the side wall of the valve core 120, for example. In this embodiment, the diameter of the first end portion of the first passage 112 is smaller than the diameter of the second end portion, the opening 111 is formed by the first end portion of the first passage 112, and the gas outlet opening 121 is formed by the gap between the second end portion and the valve core 120. One end of the valve core 120 is capable of closing the opening 111 in a linear moving direction. In this embodiment, for example as in the above embodiment, the first passage 112 also includes three portions, namely a first portion 1121 having a smaller diameter, a second portion 1122 having a larger diameter, and a connecting portion 1123 connecting the first portion 1121 and the second portion 1122. The first end portion is formed at a free end of the first portion 1121, and the second end portion is formed at a free end of the second portion 1122. One end of the valve core 120 may be inserted into the first portion 1121, thereby closing the first end portion, i.e., the opening 111. And due to the larger diameter of the second portion 1122, an annular gap is formed between it and the valve core 120, forming the gas outlet opening 121. When the valve core 120 does not close the opening 111 by a linear movement, the passage between the opening 111 and the gas outlet opening 121 is opened. At the end of the valve core 120 for closing the opening 111, for example, a closure element 125 can be provided, which comprises a first closure element 1251 and a second closure element 1252, which are arranged one behind the other in the axial direction, wherein the first closure element 1251 can be inserted into the first section 1121 and can be sealingly fastened to a side wall of the first section 1121 in order to close the opening 111. The second closure member 1252 is capable of sealing against the side wall of the connecting portion 1123 when the first closure member 1251 is inserted into the first portion 1121 to further seal the passage from the opening 111 to the gas outlet opening 121 and ensure a high degree of airtightness. In this embodiment, the gas outlet opening 121 may also be provided on a side wall of the second portion 1122 or on a side wall of the connecting portion 1123, for example. At this point, the protrusion portion 124 is still provided to surround the side wall and sealingly engage the helical groove 114.In an embodiment of the present application, the switching device 100 further includes a rotating member 130 connected to the valve core 120 and the steering member 300, respectively, and the steering member 300 drives the rotating member 130 by its own rotation, thereby further rotating the valve core 120. In alternative embodiments of the present application, the rotating element 130 may also be connected to the steering element 300 via a transmission mechanism, for example, a belt transmission mechanism, a chain transmission mechanism or a gear transmission mechanism, etc., to allow a wide range of position possibilities for the arrangement of the steering element 300 on the base station body; for example, the rotating element 130 is arranged at the lower part of the base station body and the steering element 300 is arranged at the upper side of the base station body, but of course, the above transmission mechanism may also be used to adjust the movement ratio between the steering element 300 and the rotating element 130.In an embodiment of the present application, a restricting member (not shown in the attached drawings) is provided on the rotary joint between the base station body and the handle, and the restricting member prevents the handle from further rotating after the handle is switched to the first position. The restricting member may prevent unnecessary movement of the handle under the influence of an external force or misoperation of the handle by a user in the first position, thereby preventing the adsorption device 200 from being erroneously released.
