[0004] In view of the above problems, the utility model provides a sewage tank and cleaning equipment for cleaning equipment, which can reduce the frequency of the cleaning equipment returning to the base station, improve the cleaning efficiency of the cleaning equipment, and also avoid the problem of the sewage tank stinking due to the failure to discharge solid dirt from the sewage tank in time.

[0005] The utility model provides a sewage tank of cleaning equipment, comprising: a tank body, the tank body comprising a accommodating chamber, the accommodating chamber being divided into a first accommodating chamber and a second accommodating chamber; the accommodating chamber having a sewage inlet and a sewage outlet, the sewage inlet being used to suck sewage from the outside of the tank body, and the sewage outlet being used to discharge sewage from the tank body; wherein the sewage inlet is arranged on the cavity wall of the first accommodating chamber, a solid isolation component is arranged in the tank body, the solid isolation component is at least suitable for retaining solid sewage in the sewage in the first accommodating chamber, and the second accommodating chamber is at least suitable for accommodating sewage in the sewage; the first accommodating chamber and the second accommodating chamber share the sewage outlet, and the sewage outlet is at least partially arranged on the cavity wall of the first accommodating chamber.

[0006] According to the sewage tank of the utility model, after the sewage is sucked into the sewage tank, the solid sewage in the sewage can be retained in the space near the sewage outlet. When the sewage tank is discharged by the negative pressure fan on the base station, the solid sewage can be more easily sucked into the base station, which is convenient for the effective collection of the solid sewage in the sewage cavity and avoids the phenomenon of the sewage tank stinking due to the solid sewage not being discharged from the sewage tank in time.

[0007] In some embodiments, the sewage outlet is used to communicate with the sewage suction port of the base station. In this way, when the sewage tank is discharged by the negative pressure fan on the base station, solid sewage can be more easily sucked into the base station, which facilitates the effective collection of solid sewage in the sewage chamber.

[0008] In some embodiments, the solid isolation assembly includes a first partition plate arranged on the inner side of the box body and sealedly connected to the wall of the box body, and the first partition plate is provided with a connecting port; the box body is also provided with a drainage channel connecting the first accommodating chamber and the second accommodating chamber; wherein, the drainage channel is connected with the connecting port, and is suitable for discharging the sewage in the first accommodating chamber into the second accommodating chamber in one direction.

[0009] In some embodiments, the drainage channel includes a sewage pipe, a first end of which is connected to the connecting port, a second end of which extends to the bottom of the first accommodating chamber, and the connecting port is located at a height higher than the height of the second end of the sewage pipe; a suction port is provided on the wall of the second accommodating chamber, and the suction port is suitable for connecting to a suction pump of the cleaning equipment, and the suction port is used to make the second accommodating chamber in a negative pressure state, so that the sewage in the first accommodating chamber can be discharged into the second accommodating chamber through the drainage channel.

[0010] In this way, the sewage in the first accommodating chamber can enter the second accommodating chamber under negative pressure, and it can also be ensured that the sewage in the second accommodating chamber cannot flow back into the first accommodating chamber.

[0011] In some embodiments, the solid isolation assembly also includes a water filter baffle disposed in the first accommodating chamber, the water filter baffle is connected to the wall of the first accommodating chamber, a plurality of water holes are provided on the water filter baffle, and the water holes are used to separate solid dirt and sewage in the dirt; the water filter baffle, the first baffle and the wall of the first accommodating chamber jointly define an installation space, and the sewage pipe is arranged in the installation space.

[0012] By setting up a water filter baffle, it is convenient for sewage to enter the installation space and be discharged into the second containing chamber through the sewage pipe. It can also separate the sewage pipe and solid dirt to prevent solid dirt from clogging the entrance of the sewage pipe. It can also prevent solid dirt from getting stuck in the gap between the sewage pipe and the wall of the first containing chamber, so as to facilitate subsequent sewage discharge.

[0013] In some embodiments, the bottom wall of the first accommodating cavity extends downwardly in an inclined direction from away from the second accommodating cavity to close to the second accommodating cavity, and the entrance of the drainage channel is located at the lowest point of the bottom wall of the first accommodating cavity.

[0014] In this way, the sewage in the first accommodating chamber can be fully discharged to the second accommodating chamber, and the solid dirt and sewage can be separated as much as possible.

[0015] In some embodiments, a second partition is further provided in the first accommodating chamber, the second partition is connected to the side wall of the first accommodating chamber, and together with the side wall of the first accommodating chamber, encloses a sewage discharge chamber; one end of the sewage discharge chamber has a sewage discharge inlet, and the other end has the sewage discharge outlet, and the sewage discharge inlet is at least partially connected with the first accommodating chamber; the sewage discharge outlet is arranged on the upper side of the side wall of the first accommodating chamber, and the sewage discharge chamber extends in the height direction of the box body in the first accommodating chamber, and the sewage discharge inlet is formed between the second partition and the bottom wall of the first accommodating chamber, and the sewage discharge inlet is inclined toward the first accommodating chamber.

[0016] In this way, by providing the sewage discharge cavity, it is possible to facilitate sewage discharge from the sewage tank, and the sewage discharge cavity has a simple structure and is easy to implement.

[0017] In some embodiments, the bottom wall of the second accommodating chamber is provided with a sewage outlet and a connecting channel, one end of the connecting channel is connected to the sewage outlet, and the other end extends to the first accommodating chamber; a switch assembly is provided on the sewage outlet to open and close the sewage outlet; wherein, when waste recovery is not performed, the switch assembly closes the sewage outlet; when waste recovery is performed, the trigger on the base station drives the switch assembly to open the sewage outlet.

[0018] In this way, it is convenient to discharge the sewage in the second accommodating chamber through a unified sewage discharge channel, and the discharge of sewage and the discharge of solid waste will not interfere with each other.

[0019] In some embodiments, the switch assembly includes a blocking portion and a first reset structure, the blocking portion is suitable for blocking the sewage outlet, one end of the first reset structure is connected to the blocking portion, and the other end is connected to the cavity wall of the second accommodating cavity, and the first reset structure is used to drive the blocking portion to move relative to the sewage outlet to open and close the sewage outlet.

[0020] In some embodiments, the blocking portion is disposed on the outside of the box body, a sealing ring is disposed on the outside of the peripheral wall of the blocking portion, and the peripheral wall of the sewage outlet and the sealing ring are both in a conical shape that gradually decreases toward the second accommodating cavity. In this way, when the sewage outlet is blocked, it is helpful to improve the sealing performance of the sewage outlet in a closed state.

[0021] In some embodiments, the first reset structure includes a mounting bracket, an elastic member, and a connecting rod; wherein the connecting rod is movably arranged in the sewage outlet along the axial direction of the sewage outlet, and the blocking portion is arranged at one end of the connecting rod; the mounting bracket is fixed in the box body, and the mounting bracket has a bracket end close to the sewage outlet, and when the blocking portion does not block the sewage outlet, there is a gap between the bracket end and the sewage outlet; the connecting rod passes through the bracket end, and the connecting rod is provided with a limiting portion at one end away from the bracket end and the sewage outlet, and the limiting portion is fixed on the connecting rod; the elastic member is sleeved on the outer side of the connecting rod, one end of the elastic member abuts against the bracket end, and the other end abuts against the limiting portion; when waste recovery is performed, the trigger member on the base station drives the connecting rod to move downward to drive the blocking portion to move and open the sewage outlet; when waste recovery is not performed, the blocking portion moves toward the sewage outlet under the elastic reset force of the elastic member to block the sewage outlet.

[0022] In this way, when the sweeping robot performs a cleaning task, the elastic member is under pressure and pushes the blocking member, thereby causing the blocking portion to block the sewage outlet. When the sweeping robot returns to the base station and needs to discharge sewage, the blocking member moves downward under the drive of the trigger member, compresses the elastic member, and opens the sewage outlet, so that the sewage in the second accommodating chamber can be smoothly discharged to the sewage discharge inlet.

[0023] In some embodiments, a slot is provided at one end of the mounting bracket away from the first end portion, and when the blocking portion blocks the sewage outlet, the limiting portion is at least partially stuck in the slot.

[0024] In some embodiments, the box body also includes an air suction port, which is connected to the air suction fan of the cleaning equipment, and under the action of the air suction fan, the dirt enters the first containing chamber from the outside of the box body through the sewage inlet; a liquid outlet for the cleaning liquid is also provided in the box body, and the liquid outlet is adjacent to the air suction port and away from the sewage outlet; when the box body is cleaned, gas is sucked into at least the first containing chamber from the air suction port, and the sucked gas pushes the cleaning liquid to flow toward the sewage outlet at least in the first containing chamber.

[0025] Since the first accommodating chamber mainly contains solid dirt and the environment is relatively dry, it is convenient for the exhaust fan to extract the air sucked from the sewage inlet to the exhaust port through the exhaust port and the first accommodating chamber, so that the cleaning device can smoothly suck dirt. In addition, in order to prevent sewage from being sucked into the exhaust fan, the exhaust port can be set at a higher position of the box.

[0026] In some embodiments, the sewage inlet and the sewage outlet are arranged on two opposite cavity walls of the first accommodating cavity.

[0027] In some embodiments, the liquid inlet of the cleaning device is connected to the cleaning pipeline of the base station, and the cleaning liquid flows into the cleaning device through the cleaning pipeline of the base station and the liquid inlet, and flows out from the liquid outlet; under the action of the negative pressure fan of the base station, gas is sucked into at least the first containing chamber from the air suction port, and the sucked gas pushes the cleaning liquid to flow toward the sewage outlet at least in the first containing chamber; wherein a negative pressure fan is provided in the base station, and the negative pressure fan is connected to the sewage suction port.

[0028] By providing a cleaning device, the first accommodating chamber can be thoroughly cleaned to remove dirt, kill bacteria, prevent the generation of odor, and achieve self-cleaning of the sewage tank.

[0029] In some embodiments, the box body also includes an air suction chamber, which is arranged on a side close to the first accommodating chamber, and the air suction chamber has an air inlet and an air suction port, the air suction port is arranged at the upper end of the side wall of the box body, and the air inlet is arranged close to the bottom wall of the box body; the air suction chamber is connected with the first accommodating chamber through the air inlet, and the air suction port is connected to the air suction fan of the cleaning equipment; the liquid outlet of the cleaning device is arranged in the air suction chamber, and the liquid outlet direction of the cleaning device is the airflow direction from the air suction port to the air inlet.

[0030] Since the first accommodating chamber mainly contains solid dirt and the environment is relatively dry, it is convenient for the exhaust fan to extract the air sucked into the exhaust chamber from the sewage inlet through the exhaust chamber and the first accommodating chamber, without the need to set up a complex gas-liquid separation structure.

[0031] In some embodiments, a filter is provided at the air outlet, and the filter is used to separate solid dirt and airflow; the filter is inclined toward the first accommodating cavity, and the filter covers the air outlet and part of the area around the air outlet in the projection area projected onto the plane where the air outlet is located. In this way, on the one hand, dry garbage can be prevented from being sucked into the air extraction cavity, thus preventing the air outlet from being blocked by dirt, and on the other hand, ensuring that the air extraction cavity has sufficient air intake, thereby ensuring the air extraction efficiency.

[0032] In some embodiments, a valve plate is also provided in the air suction chamber, and the valve plate is movably provided at the air outlet to adjust the flow area of ​​the air outlet; the valve plate is constructed to move away from the bottom wall of the box body when the exhaust fan draws air from the air suction chamber to increase the flow area of ​​the air outlet, and to move toward the bottom wall of the box body to reduce the flow area of ​​the air outlet when the cleaning device supplies cleaning liquid into the air suction chamber.

[0033] In this way, the valve plate can be used to adjust the flow area of ​​the air port to adjust the exhaust state of the first receiving chamber. It can ensure that the air outlet has sufficient gas flow area, and also ensure that the first receiving chamber has sufficient negative pressure to suck in garbage. The bottom edge of the valve plate after being lowered is only a small distance away from the bottom surface of the sewage tank, so that the air flow flows along the bottom wall of the sewage tank. On the one hand, it can push the dry garbage to flow toward the sewage outlet, and on the other hand, it will also push the cleaning liquid to flow toward the first receiving chamber. The water flow also further carries the solid dirt to flow toward the sewage outlet, thereby effectively improving the cleaning effect of the bottom wall of the receiving chamber.

[0034] In some embodiments, the solid isolation component includes a water-gas separation structure, which is suitable for separating water and gas from the dirt and for retaining solid dirt in the dirt in the first containing cavity.

The wet cleaning part may be a mop to perform wet cleaning on the work surface. The cleaning device may also go to the base station to clean the mop. Since the mop itself has a limited ability to carry dirt, the cleaning device needs to return to the base station more frequently, thereby affecting the cleaning efficiency of the cleaning device.

[0104] refer to Figure 1-Figure 31 In the embodiment of the utility model, a sewage tank 1 can be provided in the cleaning device 100. During the cleaning process, the cleaning device 100 can at least suck the dirt on the mop into the sewage tank 1. After the sewage tank 1 is full, the cleaning device 100 goes to the base station again, so that the base station can recycle the dirt in the sewage tank 1. This reduces the frequency of the cleaning device returning to the base station, thereby improving the cleaning efficiency of the cleaning device.

[0105] Combination Figure 1 , Figure 8 and Fig.21 The sewage tank 1 may include a housing 10. The housing 10 may be square, circular, semicircular, or any other shape. The sewage tank 1 may contain not only liquid sewage but also solid sewage. Since the solid sewage is in a humid environment, the solid sewage is easily adsorbed on the inner wall of the housing 10, so that when the base station recycles the sewage tank, the solid sewage adsorbed on the inner wall of the housing 10 is difficult to be recycled.

[0106] The housing 10 has a accommodating chamber 103, which can be divided into a second accommodating chamber 103b and a first accommodating chamber 103a. The first accommodating chamber 103a is at least suitable for retaining solid waste in the waste in the first accommodating chamber 103a, and the second accommodating chamber 103b is at least suitable for accommodating sewage in the waste.

[0107] The accommodating chamber 103 has a sewage inlet 104 and a sewage outlet 105, wherein the sewage inlet 104 is used to suck in dirt from the outside of the housing 10, and the sewage outlet 105 is used to discharge the dirt from the housing 10. For example, the sewage inlet 104 can be connected to the wiper component of the mop, so that after the wiper component scrapes the dirt on the mop, it is sucked into the sewage tank through the sewage inlet 104. After the cleaning device is docked with the base station, the sewage outlet 105 can be connected to the sewage suction port on the base station, and the negative pressure fan on the base station can be used to suck the dirt in the sewage tank from the housing 10 to the sewage collection box of the base station through the sewage outlet 105 and the sewage suction port on the base station to complete the sewage collection.

[0108] The sewage inlet 104 can be arranged on the wall of the first accommodating chamber 103a. The sewage first enters the first accommodating chamber 103a from the outside of the housing 10 through the sewage inlet 104, the solid sewage is retained in the first accommodating chamber 103a, and the sewage can flow into the second accommodating chamber 103b in whole or in part.

[0109] In some embodiments, solid dirt is retained in the first accommodating chamber 103a, and specifically, all solid dirt in the dirt is retained in the first accommodating chamber 103a. Of course, in view of solid dirt such as fine sand and soil, a higher configuration of solid-liquid separation devices (such as the solid isolation assembly 20 described below) is required to achieve a higher filtration rate. Therefore, in other embodiments, solid dirt is retained in the first accommodating chamber 103a, and specifically, part of the solid dirt in the dirt is retained in the first accommodating chamber 103a.

[0110] The first accommodating chamber 103a and the second accommodating chamber 103b share a sewage outlet 105, and the sewage in the first accommodating chamber 103a and the second accommodating chamber 103b can be discharged from the box body 10 through the sewage outlet 105. The sewage outlet 105 is at least partially arranged on the wall of the first accommodating chamber 103a, which can ensure that the solid sewage in the first accommodating chamber 103a is closer to the sewage outlet 105. Accordingly, when the negative pressure fan on the base station is used to discharge sewage from the sewage tank 1, the solid sewage can be more easily sucked into the base station, which is convenient for the effective collection of the solid sewage in the sewage chamber.

[0111] The solution provided by the above embodiment can retain solid waste in the waste in a space near the sewage outlet 105 after the waste is sucked into the sewage tank 1. When the sewage tank 1 is discharged by the negative pressure fan on the base station, the solid waste is more easily sucked into the base station, which facilitates the effective recovery of the solid waste in the sewage cavity and reduces the phenomenon of stinking of the sewage tank 1 caused by the failure to discharge the solid waste from the sewage tank 1 in time.

[0112] In some embodiments, reference Fig.13 The sewage tank 1 may further include a solid isolation component 20, which is disposed in the tank body 10 and is suitable for retaining solid waste in the first accommodating chamber 103a.

[0113] It can be understood that, depending on the structure of the solid isolation component 20, the first containing chamber 103a may also accommodate some sewage. For example, when the solid isolation component 20 has a hole structure, the hole structure can make the first containing chamber 103a and the second containing chamber 103b connected. At this time, the solid isolation component 20 can ensure that the solid dirt is only in the first containing chamber 103a, and the first containing chamber 103a and the second containing chamber 103b can respectively accommodate part of the sewage to increase the capacity for sewage.

[0114] In some embodiments, reference Fig.13 The solid isolation assembly 20 may include a first partition 201, which is disposed inside the box 10 and is sealed and connected to the wall of the box 10. In this case, the first partition 201 may separate the accommodating chamber 103 into a first accommodating chamber 103a and a second accommodating chamber 103b. For example, the first partition 201 may be connected to the side walls of the box 10 on opposite sides along the width direction. In this case, the first accommodating chamber 103a and the second accommodating chamber 103b are arranged along the length direction of the box 10. Of course, the present invention does not limit this. The specific arrangement of the first accommodating chamber 103a and the second accommodating chamber 103b may be reasonably set according to actual needs.

[0115] A connecting port 202 is provided on the first partition plate 201. Correspondingly, a drainage channel 206 connecting the first accommodating chamber 103a and the second accommodating chamber 103b is also provided in the box body 10. The drainage channel 206 and the connecting port 202 are connected to each other, so as to be suitable for unidirectionally discharging the sewage in the first accommodating chamber 103a into the second accommodating chamber 103b, while the sewage in the second accommodating chamber 103b will not enter the first accommodating chamber 103a.

[0116] Thus, by providing the first partition plate 201 with a relatively simple structure, solid dirt can be prevented from entering the second accommodating chamber 103b. At the same time, it is also beneficial for the first accommodating chamber 103a to be in a relatively dry state, which is beneficial for increasing the garbage carrying capacity of the first accommodating chamber 103a and facilitating the flow of air. The second accommodating chamber 103b can be used for other processes required to complete the cleaning task, such as discharging sewage or extracting air to generate negative pressure.

[0117] Optionally, the sewage inlet 104 may be provided with a dirt blocking piece to prevent the dirt entering the first accommodating chamber 103 a from overflowing from the sewage inlet 104 in the reverse direction.

[0118] In some embodiments, reference Fig.13 and Fig.14 , a connecting port 202 is provided on the first partition 201, and the drainage channel 206 may also include a sewage pipe. Specifically, the first end of the sewage pipe (e.g., the upper end of the sewage pipe) is connected to the connecting port 202, and the second end of the sewage pipe (e.g., the bottom end of the sewage pipe) extends to the bottom of the first accommodating chamber 103a. The sewage pipe defines the drainage channel 206, and the height of the connecting port 202 is higher than the height of the second end of the sewage pipe. For example, the connecting port 202 can be provided at a position close to the top edge of the first partition 201. In this way, the sewage in the first accommodating chamber 103a can enter the second accommodating chamber 103b under negative pressure, and it can also be ensured that the sewage in the second accommodating chamber 103b cannot flow back into the first accommodating chamber 103a.

[0119] Correspondingly, a suction port 107 is provided on the cavity wall of the second accommodating cavity 103b, and the suction port 107 is suitable for communicating with the suction pump of the cleaning device 100. The suction port 107 is used to make the second accommodating cavity 103b present a negative pressure state, so that the sewage in the first accommodating cavity 103a is discharged into the second accommodating cavity 103b through the drainage channel 206. In this way, when the suction pump draws the second accommodating cavity 103b into a negative pressure through the suction port 107, the sewage in the first accommodating cavity 103a is discharged into the second accommodating cavity 103b through the drainage channel 206, and the solid dirt is trapped in the first accommodating cavity 103a. Among them, the suction port 107 can be provided on the side wall of the second accommodating cavity 103b.

[0120] In some embodiments, the solid isolation assembly 20 also includes a water filter baffle disposed in the first accommodating chamber 103a, the water filter baffle is connected to the wall of the first accommodating chamber 103a, and a plurality of water holes are provided on the water filter baffle, which are used to separate solid dirt and sewage in the dirt.

[0121] The water filter baffle, the first baffle 201 and the side wall of the first accommodating chamber 103a jointly define an installation space, and the sewage pipe included in the drainage channel 206 is arranged in the installation space. For example, as an optional specific structure, the water filter baffle extends vertically, and the water filter baffle can be arc-shaped, one end of the water filter baffle is connected to the side wall of the box body 10, and the other end is connected to the first baffle 201. In this way, the water filter baffle and the box body 10 and the first baffle 201 jointly define an installation space. In addition, the water holes arranged on the water filter baffle can allow sewage to smoothly enter the installation space and be discharged into the second accommodating chamber 103b through the sewage pipe.

[0122] By setting up a water filter baffle, it is convenient for sewage to enter the installation space and be discharged into the second accommodating chamber 103b through the sewage pipe. It can also separate the sewage pipe and solid waste to prevent solid waste from clogging the entrance of the sewage pipe. It can also prevent solid waste from getting stuck in the gap between the sewage pipe and the wall of the first accommodating chamber 103a, so as to facilitate subsequent sewage discharge.

[0123] In some embodiments, the bottom wall of the first accommodating chamber 103a extends downwardly from away from the second accommodating chamber 103b to close to the second accommodating chamber 103b, and the entrance of the drainage channel 206 is located at the lowest point of the bottom wall of the first accommodating chamber 103a. In this way, the sewage in the first accommodating chamber 103a can be fully discharged to the second accommodating chamber 103b, and the solid dirt and sewage can be separated as much as possible, so as to facilitate the later sewage tank 1 to discharge sewage.

[0124] In some embodiments, reference Fig.15A second partition 111 may also be provided in the first accommodating chamber 103a of the box body 10. The second partition 111 is connected to the side wall of the first accommodating chamber 103a, and together with the side wall of the first accommodating chamber 103a, a sewage discharge chamber 112 is enclosed. One end of the sewage discharge chamber 112 (e.g., the bottom end of the sewage discharge chamber 112) has a sewage discharge inlet 113, and the other end (e.g., the top end of the sewage discharge chamber 112) has a sewage discharge outlet 105. The sewage discharge inlet 113 is at least partially connected to the first accommodating chamber 103a. The sewage discharge outlet 105 is suitable for extracting the sewage in the sewage tank 1 through negative pressure to facilitate sewage discharge of the sewage tank 1, and the sewage discharge chamber 112 has a simple structure and is easy to implement.

[0125] Among them, the sewage outlet 105 is arranged on the upper side of the side wall of the first accommodating chamber 103a, the sewage chamber 112 extends in the first accommodating chamber 103a along the height direction of the box body 10, and a sewage inlet 113 is formed between the second partition plate 111 and the bottom wall of the first accommodating chamber 103a. The sewage inlet 113 is inclined facing the first accommodating chamber 103a, and the opening direction of the sewage inlet 113 is toward the first accommodating chamber 103a, so as to facilitate the sewage from the first accommodating chamber 103a to enter the sewage inlet 113.

[0126] In some embodiments, in combination Figure 15-18 A sewage outlet 114 and a connecting channel 115 are provided on the bottom wall of the second accommodating chamber 103b, one end of the connecting channel 115 is connected to the sewage outlet 114, and the other end extends to the sewage inlet 113; a switch assembly 50 can also be provided on the sewage outlet 114 of the sewage tank 1 to open and close the sewage outlet 114; wherein, when the sewage tank 1 does not perform waste recovery, the switch assembly 50 closes the sewage outlet 114; when the sewage tank 1 performs waste recovery, the trigger on the base station drives the switch assembly 50 to open the sewage outlet 114.

[0127] Among them, illustratively, the connecting channel 115 can be located on the lower side of the bottom wall of the second accommodating chamber 103b, and extend from the lower side of the first partition 201 to the sewage inlet 113, so as to facilitate the discharge of sewage in the second accommodating chamber 103b, and the discharge of sewage and the discharge of solid waste do not interfere with each other.

[0128] In some embodiments, a trigger is provided on the base station of the cleaning device 100. The switch assembly 50 may include a blocking portion 503 and a first reset structure, wherein the blocking portion 503 is adapted to block the sewage outlet 114, one end of the first reset structure is connected to the blocking portion 503, and the other end is connected to the cavity wall of the second accommodating cavity 103b, and the first reset structure is used to drive the blocking portion to move relative to the sewage outlet 114 to open or close the sewage outlet 114.

[0129] Specifically, the switch assembly 50 may include a blocking member 501, and the blocking portion 503 is disposed on the blocking member 501. When the cleaning device 100 moves to the base station, the trigger member drives the blocking portion 503 to move to open the sewage outlet 114; and when the trigger member and the blocking member 501 and other structures are out of contact, the first reset structure can be reset to restore the blocking portion 503 to its original position and close the sewage outlet 114. In this way, it is more convenient to realize the automatic discharge of sewage in the second accommodating chamber 103b when the cleaning device is docked with the base station.

[0130] Optional, such as Fig.16 As shown, the blocking portion 503 is disposed on the outside of the box body 10, a sealing ring is disposed on the outer side of the peripheral wall of the blocking portion 503, and the peripheral wall and the sealing ring of the sewage outlet 114 are both in a conical shape with a diameter gradually decreasing toward the second accommodating chamber 103b. In this way, when the sewage outlet 114 is blocked, it is beneficial to improve the sealing performance of the sewage outlet 114 in the closed state.

[0131] Optional, such as Fig.16 and Fig.17 As shown, the first reset structure includes a mounting bracket 504 , an elastic member 505 and a connecting rod 502 ; wherein the connecting rod 502 is movably disposed in the sewage outlet 114 along the axial direction of the sewage outlet 114 , and the blocking portion 503 is disposed at one end of the connecting rod 502 .

[0132] The mounting bracket 504 is fixed in the box body 10 . The mounting bracket 504 has a bracket end close to the sewage outlet 114 . When the blocking portion 503 does not block the sewage outlet 114 , there is a gap between the bracket end and the sewage outlet 114 .

[0133] The connecting rod 502 passes through the end of the bracket, and a limiting portion 506 is provided at one end of the connecting rod 502 away from the end of the bracket and the sewage outlet 114, and the limiting portion 506 is fixed on the connecting rod 502; and the elastic member 505 is sleeved on the outer side of the connecting rod 502, and one end of the elastic member 505 abuts against the end of the bracket, and the other end abuts against the limiting portion 506. The elastic member 505 can be a spring or other element.

[0134] When waste recovery is performed in the sewage tank 1, the trigger member on the base station drives the connecting rod 502 to move downward, thereby driving the blocking portion 503 to move and open the sewage outlet 114; when waste recovery is not performed, the blocking portion 503 moves toward the sewage outlet 114 under the elastic restoring force of the elastic member 505 to block the sewage outlet 114.

[0135] In this way, when the sweeping robot returns to the base station and needs to discharge sewage, the blocking member 501 moves downward under the drive of the trigger, compresses the elastic member 505, and opens the sewage outlet 114, so that the sewage in the second accommodating chamber 103b can be smoothly discharged to the sewage inlet 113. When the sweeping robot performs the cleaning task, the elastic restoring force of the elastic member 505 pushes the blocking member 501 to move upward, thereby causing the blocking portion 503 to block the sewage outlet 114.

[0136] Optionally, a slot 507 is provided at one end of the mounting bracket 504 away from the end of the bracket. When the blocking portion 503 blocks the sewage outlet 114, the limiting portion 506 is at least partially stuck in the slot 507. In this way, the position of the connecting rod 502 is limited, which can prevent the connecting rod from floating up and down when the sweeper is bumpy during movement, causing sewage to leak out of the sewage outlet 114.

[0137] In addition, in an optional manner, the switch assembly 50 includes a rubber part, which is coated on the outside of the connecting rod 502. The rubber part can constitute a sealing portion 503. Since the rubber part has a certain elasticity, it can improve the sealing of the sewage outlet 114 in a closed state. The rubber part and the connecting rod 502 can be integrally cast to improve the connection strength.

[0138] In some embodiments, the triggering member is a magnetic member, and the connecting rod 502 is a magnetic member. In this way, the triggering member has a simple structure, low cost, and is easy to implement.

[0139] As an alternative embodiment, refer to Fig.18 The elastic reset member 505 can be replaced by a magnetic ring, which is fixed on the bottom wall of the box body 10 and located at the periphery of the sewage outlet 114. The magnetic ring has a magnetic force on the blocking portion 503, and the magnetic force of the magnetic ring on the connecting rod 502 is smaller than the magnetic force of the trigger member on the base station on the connecting rod 502. In this way, it can be ensured that when the cleaning device 100 is working outside the base station, the sewage outlet 114 can be closed normally, and when the cleaning device 100 is in the base station, the trigger member can smoothly trigger the blocking member 501 to open the sewage outlet 114.

[0140] In some embodiments, reference Figure 1 , Figure 2 , Fig.10 and Fig.21 The box body also includes an air suction port, which is connected to the air suction fan of the cleaning equipment. Under the action of the air suction fan, dirt enters the first accommodating chamber 103a from the outside of the box body 10 through the sewage inlet 104.

[0141] Correspondingly, a cleaning device 40 is also provided in the box body 10, and the cleaning device 40 has a liquid outlet 404 for cleaning liquid, and the liquid outlet 404 is arranged near the air suction port and away from the sewage outlet; when the box body 10 is cleaned, gas is sucked from the air suction port into at least the first accommodating chamber 103a, and the sucked gas pushes the cleaning liquid to flow toward the sewage outlet at least in the first accommodating chamber 103a.

[0142] In some embodiments, the air suction port can be arranged on a side away from the sewage outlet. If the air suction port is arranged near the first accommodating chamber, and the sewage outlet is arranged between the two accommodating chambers, the air suction port can be arranged on the side wall of the box body away from the sewage outlet. If the air suction port is arranged on a side near the second accommodating chamber, and the sewage outlet is arranged in the first accommodating chamber, the air suction port and the sewage outlet are arranged at both ends of the box body respectively. Correspondingly, the liquid outlet is close to the air suction port and far away from the sewage outlet, then the liquid outlet and the sewage outlet are arranged at opposite ends of the first accommodating chamber, or the liquid outlet and the sewage outlet are arranged at opposite ends of the box body, so that the cleaning liquid can flow from one end of the first accommodating chamber to the other end, thereby improving the cleaning coverage rate of the first accommodating chamber; or, flow from one end of the box body to the other end, thereby improving the coverage rate; and the direction of the water flow can also flow from one end of the first accommodating chamber to one end of the first accommodating chamber, and then be discharged from the sewage outlet, so that the solid waste in the first accommodating chamber is completely taken away by the water flow.

[0143] The first accommodating chamber 103a and other structures can be cleaned by cleaning liquid to remove dirt, kill bacteria, prevent odor, and realize self-cleaning of the sewage tank 1; and the gas can be blown into the air outlet to drive the cleaning liquid to flow in the first accommodating chamber 103a. In this way, the diffusion efficiency of the cleaning liquid is improved, so as to improve the cleaning efficiency.

[0144] Specifically, in some optional embodiments, the liquid inlet of the cleaning device is connected to the cleaning pipeline of the base station, and the cleaning liquid flows into the cleaning device through the cleaning pipeline of the base station and the liquid inlet, and flows out from the liquid outlet 404.

[0145] Under the action of the negative pressure fan of the base station, gas is sucked from the air suction port into at least the first accommodating chamber 103a, and the sucked gas pushes the clean liquid to flow toward the sewage outlet 114 at least in the first accommodating chamber 103a; wherein, a negative pressure fan is provided in the base station, and the negative pressure fan is connected to the sewage suction port of the base station. At this time, the negative pressure fan of the base station can provide a suction airflow, and the gas sucked by the sewage tank 1 pushes the clean liquid to flow.

[0146] Alternatively, the exhaust fan of the above-mentioned cleaning equipment 100 can also be controlled to reverse and blow air into the exhaust chamber 108 to drive the cleaning liquid to flow from one side of the exhaust chamber 108 to the side of the first accommodating chamber 103a. In this way, a separate device for blowing air into the exhaust chamber 108 is omitted, which is conducive to simplifying the overall structure and reducing costs.

[0147] In some embodiments, the sewage inlet 104 and the sewage outlet are arranged on two opposite walls of the first accommodating chamber 103a. When the sweeper is docked with the base station, airflow will flow into the box from the sewage inlet 104, so that the airflow path formed between the sewage inlet 104 and the sewage outlet can be utilized, and the airflow further drives the water flow to drive the solid waste from the sewage inlet outlet to the sewage outlet, further improving the effect of solid waste cleaning.

[0148] Continue to refer Figure 1 , Figure 2 as well as Fig.10 In some embodiments, the box body 10 may further include an air extraction cavity 108 , which has an air inlet and an air extraction port. The air extraction port is arranged at the upper end of the side wall of the box body 10 , and the air inlet is arranged close to the bottom wall of the box body 10 .

[0149] refer to Fig.10 The air extraction chamber 108 is arranged on a side close to the first accommodating chamber 103a and communicates with the first accommodating chamber 103a through the air port. In the scheme where the air extraction chamber 108 is arranged on a side close to the first accommodating chamber 103a and communicates with the first accommodating chamber 103a through the air port, since the first accommodating chamber 103a mainly contains solid dirt and the environment is relatively dry, it is convenient for the air extraction fan to extract the air sucked into the air extraction chamber 108 from the sewage inlet 104 through the air extraction chamber 108 and the first accommodating chamber 103a, without the need to arrange a complex gas-liquid separation device, thereby improving the simplicity of the structure.

[0150] The air suction port is suitable for connecting to the air suction fan of the cleaning device 100. Under the action of the air suction fan, the dirt enters the first accommodating chamber from the outside of the box through the dirt inlet port.

[0151] The liquid outlet 404 of the cleaning device 40 is disposed in the air extraction chamber 108 , and the liquid outlet direction of the cleaning device 40 is the air flow direction from the air extraction port to the air outlet.

[0152] The air suction port is arranged at a higher position in the air suction chamber 108 to prevent sewage from being sucked into the air suction fan. The air inlet is arranged near the bottom wall of the box body 10, and the liquid outlet 404 of the cleaning device 40 is arranged in the air suction chamber 108, and the liquid outlet direction of the cleaning device 40 is the air flow direction from the air suction port to the air inlet, so that the liquid can follow the air flow from the air inlet to flow into the bottom of the first accommodating chamber or the second accommodating chamber, and the solid waste is taken away by the water flow, so that the solid waste can be cleaned more cleanly.

[0153] In some embodiments, reference Figure 1 , Fig.15 and Fig. 20 At least part of the structure of the cleaning device 40 in the sewage tank 1 is arranged in the air suction chamber 108 to pass a cleaning liquid into the air suction chamber 108. The cleaning liquid can be clean water or a cleaning solution containing a detergent. The cleaning liquid is suitable for flowing from the air suction chamber 108 to the first accommodating chamber 103a to clean the first accommodating chamber 103a and is discharged from the sewage outlet 105. By providing the cleaning device 40, the first accommodating chamber 103a can be thoroughly cleaned to remove dirt, kill bacteria, prevent odor, and realize self-cleaning of the sewage tank 1.

[0154] In some embodiments, reference Fig.15 The cleaning device 40 may include a first liquid supply channel 401, which is disposed on the side wall of the vacuum chamber 108. The first liquid supply channel 401 has a plurality of liquid outlets 404, and the plurality of liquid outlets 404 are distributed at intervals. By providing a plurality of liquid outlets 404, liquid can be discharged from a plurality of positions at the same time to expand the coverage and diffusion efficiency of the cleaning liquid.

[0155] Optionally, the first liquid supply channel 401 may include a plurality of liquid outlet branches, and each liquid outlet 404 is located on a corresponding liquid outlet branch.

[0156] Optionally, the portion of each liquid outlet branch adjacent to the liquid outlet 404 extends in the vertical direction. In this case, the opening of the liquid outlet 404 faces downward so that the cleaning liquid flows toward the bottom wall of the suction chamber 108 and flows along the bottom wall into the first accommodating chamber 103a.

[0157] In some embodiments, the sewage outlet 105 is located on a side of the first accommodating chamber 103a away from the cleaning device 40, so that after the cleaning liquid enters the first accommodating chamber 103a, it can cover most of the area of ​​the first accommodating chamber 103a as much as possible to improve the cleaning effect.

[0158] In some embodiments, in combination Fig.13 and Fig.15 The sewage tank 1 of the cleaning device 100 may also include a filter element 109, which is arranged at the air outlet and is used to separate solid dirt and airflow; the filter element 109 is inclined toward the first accommodating cavity 103a, and the filter element 109 covers the air outlet and part of the area around the air outlet in the projection area projected onto the plane where the air outlet is located.

[0159] Specifically, the filter element 109 can be a filter plate, and a plurality of filter holes are arranged on the filter plate. The filter element 109 is arranged obliquely at the air outlet, and the projection of the filter element 109 at least covers the air outlet, and can be effectively placed in front of the air outlet to filter solids. In this way, on the one hand, dry garbage can be prevented from being sucked into the air extraction chamber 108, so as to avoid the inability to clean it up during self-cleaning, and on the other hand, the air outlet position can be prevented from being blocked by dirt, so as to ensure that the air extraction chamber 108 has sufficient air intake, thereby ensuring the air extraction efficiency.

[0160] The filter element 109 can also be configured as a water-gas separation structure to prevent sewage from entering the suction chamber 108 and being sucked into the suction fan to damage electrical components, thereby improving reliability.

[0161] In some embodiments, reference Fig.13 The sewage tank 1 may further include a valve plate 110, which is movably disposed at the air outlet to adjust the flow area of ​​the air outlet; the valve plate 110 is constructed to move in a direction away from the bottom wall of the box body 10 when the exhaust fan exhausts air from the exhaust chamber 108 to increase the flow area of ​​the air outlet, and to move in a direction close to the bottom wall of the box body 10 when the cleaning device 40 supplies cleaning liquid into the exhaust chamber 108 to reduce the flow area of ​​the air outlet.

[0162] In this way, when the exhaust fan extracts air from the exhaust chamber 108, the valve plate 110 moves away from the bottom wall of the exhaust chamber 108, which can ensure that the exhaust port has sufficient gas flow area and that the first accommodating chamber 103a has sufficient negative pressure to suck in garbage.

[0163] When the cleaning device 40 supplies cleaning liquid into the air extraction chamber 108, the valve plate 110 moves toward the bottom wall of the air extraction chamber 108. The bottom edge of the valve plate 110 after being lowered is only a small distance away from the bottom surface of the sewage tank 1, so that the airflow flows along the bottom wall of the sewage tank 1, which can push the dry garbage to flow toward the sewage outlet 105 on the one hand, and push the cleaning liquid to flow toward the first accommodating chamber 103a on the other hand, and the water flow also further carries the solid dirt to flow toward the sewage outlet 105, thereby effectively improving the cleaning effect of the bottom wall of the accommodating chamber 103.

[0164] Specifically, the valve plate 110 is disposed in the air extraction cavity 108, and the area of ​​the valve plate 110 is suitable for covering the air port. Thus, the valve plate 110 can be used to adjust the flow area of ​​the air port to adjust the exhaust state of the first accommodating cavity 103a.

[0165] In some embodiments, reference Fig.13The cleaning device 40 may further include a second liquid supply channel 402, which is disposed on the side wall of the second accommodating chamber 103b. The outlet of the second liquid supply channel 402 is connected to the second accommodating chamber 103b to introduce cleaning liquid into the second accommodating chamber 103b. In this way, the second accommodating chamber 103b can be cleaned to prevent bacteria from growing in the second accommodating chamber 103b and generating odor.

[0166] Optionally, the portion of the second liquid supply channel 402 adjacent to its own outlet extends in the vertical direction, with the outlet facing the bottom wall of the second accommodating chamber 103b. In this way, the bottom wall of the second accommodating chamber 103b can be flushed with clean liquid to prevent dirt deposition and bacterial growth, thereby ensuring the cleanliness of the second accommodating chamber 103b.

[0167] Optionally, the bottom wall of the second accommodating chamber 103b may also be an inclined surface, and the sewage outlet 114 is located at the lowest point of the bottom wall to ensure that the sewage is fully drained and avoid sewage residue.

[0168] In some embodiments, reference Fig.10 , the cleaning device 40 may include a liquid inlet pipe 403. Specifically, the inlet end of the liquid inlet pipe 403 is arranged on the side wall of the second accommodating chamber 103b to be connected with the external liquid supply device, and the liquid inlet pipe 403 is respectively connected with the first liquid supply channel 401 and the second liquid supply channel 402. For example, the liquid inlet pipe 403 may include a first pipeline and a second pipeline. The first pipeline may sequentially pass through the second accommodating chamber 103b, the first accommodating chamber 103a and the air extraction chamber 108 to reach the side wall of the air extraction chamber 108 to be connected with the first liquid supply channel 401, and the second pipeline may extend along the side wall of the second accommodating chamber 103b to be connected with the second liquid supply channel 402. By providing the liquid inlet pipe 403, the cleaning liquid can be conveniently sent to the first liquid supply channel 401 and the second liquid supply channel 402.

[0169] In some embodiments, reference Fig.10 The air extraction chamber 108 and the second accommodating chamber 103b are respectively located on opposite sides of the first accommodating chamber 103a. For example, the air extraction chamber 108 is located on the right side of the first accommodating chamber 103a, and the second accommodating chamber 103b is located on the left side of the first accommodating chamber 103a. In this way, when the air extraction chamber 108 is evacuated, the sewage discharged from the second accommodating chamber 103b to the sewage discharge chamber 112 can be prevented from being drawn into the air extraction chamber 108, thereby avoiding damage to the electrical appliance.

[0170] In addition to the above embodiments, considering that cleaning equipment 100 such as a sweeping robot may need to overcome obstacles or be manually flipped over when performing cleaning tasks, in order to avoid the problem of dirt overflowing in the above process, this embodiment provides a sewage inlet valve 116 at the sewage inlet 104 of the sewage tank 1, and the sewage inlet valve 116 is used to open and close the sewage inlet 104, and an air intake valve 117 is provided at the air suction port, and the air intake valve 117 is used to open and close the air suction port, thereby improving the overall sealing of the sewage tank 1, thereby ensuring that the sewage tank 1 does not leak during the obstacle surmounting or flipping process of the cleaning equipment 100.

[0171] In some embodiments, in combination Figure 1-Figure 5 , one end of the sewage inlet valve 116 is pivotally connected to one side edge of the sewage inlet 104, and one end of the air inlet valve 117 is pivotally connected to one side edge of the air extraction port. For example, the sewage inlet 104 and the air extraction port can be square, circular or any other shape, one side edge of the sewage inlet 104 is provided with a first pivot hole, one end of the sewage inlet valve 116 is provided with a first pivot shaft, and the sewage inlet valve 116 is assembled by passing the first pivot shaft through the first pivot hole; correspondingly, one side edge of the air extraction port is provided with a second pivot hole, one end of the air inlet valve 117 is provided with a second pivot shaft, and the air inlet valve 117 is assembled by passing the second pivot shaft through the second pivot hole. In this way, the installation method of the sewage inlet valve 116 and the air inlet valve 117 is relatively simple and easy to implement.

[0172] Of course, the air inlet valve 117 and the sewage inlet valve 116 may also be closed by other means on the sewage inlet and the air exhaust port, and the air inlet valve 117 and the sewage inlet valve 116 may not be directly covered on the sewage inlet or the air exhaust port, as long as the waste cannot flow in or out of the box body, and the air flow cannot flow in or out of the box body driven by the fan.

[0173] Furthermore, in order to ensure that the sewage inlet valve 116 and the air inlet valve 117 are in a normally closed state when there is no external force (for example, when the cleaning device 100 stops cleaning), a second reset structure is provided between the sewage inlet valve 116 and the air inlet valve 117 and the housing 10, respectively, and the second reset structure enables the sewage inlet valve 116 and the air inlet valve 117 to seal the sewage inlet 104 and the air extraction port, respectively. The second reset structure can be an elastic member, a magnetic member, etc. For example, the elastic force of the elastic member is used to make the sewage inlet valve 116 and the air inlet valve 117 closed, respectively. In this way, the overall sealing of the sewage tank 1 can be ensured, thereby ensuring that the sewage tank 1 does not leak out of the sewage tank 1 during the obstacle crossing or flipping process of the cleaning device 100.

[0174] In some embodiments, in combination Figure 3-Figure 5, the cleaning device may further include a linkage mechanism. Specifically, the linkage mechanism is respectively connected to the sewage inlet valve 116, the air inlet valve 117 and the cleaning element 25 of the cleaning device 100, and the linkage mechanism is suitable for controlling the synchronous movement of the sewage inlet valve 116, the air inlet valve 117 and the cleaning element 25 of the cleaning device 100. In this way, when the cleaning element 25 is lifted and lowered, the sewage inlet valve 116 and the air inlet valve 117 are driven to move through the linkage mechanism to open or close the sewage inlet port 104 and the air extraction port respectively.

[0175] The cleaning element 25 may include a cleaning bracket and a cleaning piece, wherein the cleaning piece is mounted on the cleaning bracket and may include a roller brush, a mop, a side brush, and the like.

[0176] The cleaning device 100 may include a device body 2 and a driving mechanism 21, and the driving mechanism 21 may include a driving member 22. Specifically, the driving member 22 is fixedly arranged on the device body 2, and the driving member 22 may be a driving motor or other driving devices. The device body 2 may be provided with a working chamber, and the cleaning element 25 may be arranged in the working chamber in a lifting manner. The driving member 22 is connected to the cleaning element 25, and the driving member 22 is suitable for driving the cleaning element 25 to perform lifting movement in the working chamber. For example, the driving mechanism is connected to the cleaning bracket to drive the cleaning element to perform lifting movement.

[0177] refer to Figure 4 and Figure 5 The driving mechanism 2 may include a second rope assembly 27, one end of which is connected to the driving member 22, and the other end of the second rope assembly 27 is connected to the cleaning element 25. The driving member 22 is suitable for driving the second rope assembly 27 to retract and extend to drive the cleaning element 25 to move up and down.

[0178] In this way, when performing a cleaning task, the cleaning element 25 can be lowered to the cleaning position to clean the surface to be cleaned, and when performing operations such as overcoming obstacles or carpets, the cleaning element 25 can be raised to facilitate overcoming obstacles or working on carpets.

[0179] Alternatively, the cleaning element 25 may be passively raised and lowered. For example, when the cleaning device 100 is moving, the cleaning element 25 may be passively raised by being squeezed by an obstacle.

[0180] Based on the linkage mechanism, when the cleaning element 25 rises, the sewage inlet valve 116 and the air inlet valve 117 are synchronously driven to move, and the sewage inlet port 104 and the air extraction port are closed, so that the sewage in the sewage tank 1 is more effectively prevented from leaking out of the sewage tank 1 during the obstacle crossing process of the cleaning device 100. When the cleaning element 25 descends, the sewage inlet valve 116 and the air inlet valve 117 can be synchronously driven to move, and the sewage inlet port 104 and the air extraction port can be opened to perform cleaning.

[0181] At the same time, the movement of the sewage inlet valve 116, the air intake valve 117 and the cleaning element 25 of the cleaning device 100 can be synchronously controlled through the same driving mechanism 21, and it is also possible to eliminate the need to configure corresponding driving mechanisms for the sewage inlet valve 116 and the air intake valve 117, which is conducive to simplifying the overall structure and control logic, and takes up less space.

[0182] refer to Figure 3-Figure 5 , the sewage inlet valve 116 and the air inlet valve are arranged on the inner side of the box body 10. The sewage inlet valve 116 and the air inlet valve 117 are respectively arranged on the inner side of the box body 10. In the process of opening or closing the sewage inlet port 104 or the air extraction port, the valve (including the sewage inlet valve 116 and the air inlet valve 117) moves on the inner side of the box body 10, which can avoid occupying a large space on the outer side of the box body 10 during the movement of the valve, thereby improving the compactness of the device body 2 as a whole. Accordingly, in some embodiments, the sewage inlet valve 116 and the air inlet valve 117 are respectively arranged on the inner side of the box body, and a second reset structure is respectively arranged between the sewage inlet valve 116 and the air inlet valve 117 and the box body 10, and the second reset structure enables the sewage inlet valve 116 and the air inlet valve 117 to seal the sewage inlet port 104 and the air extraction port respectively.

[0183] Combination Fig.28 and Fig.29 , an operation port 119 is provided at one side of the sewage inlet 104, and a sealing member 124 may be provided in the operation port 119, and the sealing member 124 may move toward the inside or outside of the box body 10 in the operation port 119, and the sealing member 124 maintains the sealing of the operation port 119 during the movement toward the inside or outside of the box body 10. The movement of the sealing member 124 may be that the sealing member 124 moves as a whole in the operation port 119. Alternatively, the sealing member 124 has a certain elastic deformation amount, and the movement of the sealing member 124 may refer to that the sealing member 124 generates a certain deformation displacement toward the inside or outside of the box body 10.

[0184] Combination Fig.29 The linkage mechanism may include a transmission assembly arranged outside the housing 10 and a linkage member arranged inside the housing 10, and one end of the seal 124 outside the housing 10 is connected to the transmission assembly, and one end of the seal 124 inside the housing 10 is connected to the linkage member. In the case where the valve (including the above-mentioned sewage inlet valve 116 and air inlet valve 117) is arranged inside the housing 10, by setting the operating port 119 and the seal 124, the synchronous linkage between the inside and outside of the housing 10 is indirectly realized by using the seal 124, while ensuring the synchronous linkage, it is possible to prevent dirt from entering and exiting the housing 10 through the operating port 119, and effectively prevent dirt from overflowing. At the same time, it is also possible to avoid setting the linkage mechanism through the sewage inlet 104, which causes dirt to affect the stability of the linkage mechanism.

[0185] The input end of the transmission assembly is connected to the cleaning element 25, and the output end of the transmission assembly is connected to one end of the seal 124 outside the box 10. One end of the seal 124 inside the box 10 is connected to the sewage inlet valve 116. One end of the linkage is connected to the sewage inlet valve 116, and the other end of the linkage is connected to the air inlet valve 117.

[0186] In view of the fact that the sewage inlet valve 116 needs to keep the sewage inlet 104 sealed by the reset structure, when there is no other force, the sewage inlet valve 116 has a tendency to move toward the outside of the box body 10 under the action of the reset force, and by connecting one end of the sealing member 124 to the transmission assembly disposed on the outside of the box body 10 and one end to the sewage inlet valve 116, and the sewage inlet valve 116 is further connected to the linkage member disposed on the inside of the box body 10, the reset force of the sewage inlet valve 116 can be effectively utilized. When it is necessary to open the sewage inlet 104, the transmission assembly applies a force to the sealing member 124, and the sealing member 124 applies a force to the sewage inlet valve 116, so that the sewage inlet valve 116 overcomes the reset force, moves toward the inside of the box body 10, and opens the sewage inlet 104. When the sewage inlet 104 needs to be closed, the transmission component can cancel the force applied to the sealing member 124, and the sewage inlet valve 116 can move toward the outside of the box body 10 based on the above-mentioned reset force, thereby pushing the sealing member 124 to move toward the outside of the box body 10. The linkage member arranged on the inner side of the box body 10 drives the air inlet valve 117 to move based on the movement of the sewage inlet valve 116, thereby realizing linkage. In this way, the complexity of the movement control of the transmission component can be reduced and the structure can be simplified.

[0187] In some embodiments, the transmission assembly may include a first connecting rod 23, a second connecting rod 24, and a connecting shaft 26. One end of the first connecting rod 23 is rotatably connected to the device body 2, and one end of the second connecting rod 24 is connected to the first connecting rod 23. When the first connecting rod 23 rotates, the second connecting rod 24 is driven to move between the first position and the second position.

[0188] refer to Fig.29 The first connecting rod 23 is provided with a sliding hole 231, which is in the shape of an elongated strip, and the length direction of the sliding hole 231 extends along the length direction of the first connecting rod 23. The sliding hole 231 has a transverse wall surface and a longitudinal wall surface, and the longitudinal wall surface is the two end surfaces of the sliding hole 231 in the length direction, and the extension direction of the transverse wall surface is parallel to the length direction of the sliding hole 231.

[0189] One end of the connecting shaft 26 can be inserted into the sliding hole 231 of the first connecting rod 23, and the other end can be connected to the cleaning element 25. For example, the connecting shaft 26 can be a shaft pin, one end of which can be installed on the cleaning bracket of the cleaning element 25, and the other end can be inserted into the sliding hole 231.

[0190] During the lifting and lowering movement of the cleaning element 25 in the working chamber, the connecting shaft 26 is driven to move in the sliding hole 231 of the first connecting rod 23 along the length direction of the sliding hole 231. During the movement of the connecting shaft 26, the connecting shaft 26 can also apply a force to the lateral end surface of the sliding hole 231, so that the first connecting rod 23 rotates around the rotating shaft 28 under the push of the connecting shaft 26.

[0191] refer to Fig.28 and Fig.29 The first connecting rod 23 can be in contact with the second connecting rod 24 . During the rotation of the first connecting rod 23 , the first connecting rod 23 can be driven to move toward the inside of the box body 10 or toward the outside of the box body 10 .

[0192] refer to Figure 3-Figure 5 , the sewage inlet valve 116 can keep the sewage inlet 104 closed under the action of elastic parts, magnetic parts, etc., so as to seal the sewage inlet 104. When the cleaning element 25 contacts the surface to be cleaned to clean the surface to be cleaned, under the action of the connecting shaft 26, the second connecting rod 24 drives the first connecting rod 23 to be in the first position, and the first connecting rod 23 applies a force to the sealing member 124 toward the inside of the box body 10, so that the sealing member 124 abuts against the sewage inlet valve 116, so that the sewage inlet valve 116 is in a specified position, wherein the specified position refers to the position that the sewage inlet valve 116 needs to maintain when the sewage tank 1 is working to suck sewage.

[0193] When the cleaning element 25 rises, it can drive the connecting shaft 26 to move in the sliding hole 231. While moving, the connecting shaft 26 can drive the first connecting rod 23 to rotate in the first direction. The force of the first connecting rod 23 acting on the second connecting rod 24 is reduced. The sewage inlet valve 116 can move in the direction of sealing the sewage inlet 104 under the action of elasticity, magnetism and the like, and then push the sealing member 124 to move toward the outside of the box body 10 until the cleaning element 25 rises to the predetermined position. Accordingly, the sewage inlet valve 116 closes the sewage inlet 104 to achieve sealing of the sewage inlet 104.

[0194] When the cleaning element 25 descends, it can drive the connecting shaft 26 to move in the sliding hole 231. While moving, the connecting shaft 26 can drive the first connecting rod 23 to rotate in the second direction. The second direction is opposite to the first direction. The force of the first connecting rod 23 acting on the second connecting rod 24 increases. Driven by the first connecting rod 23, the second connecting rod 24 moves toward the inner side of the box body 10, and then pushes the sealing member 124 to move toward the inner side of the box body 10. The sealing member 124 then pushes the sewage inlet valve 116 to overcome the elastic, magnetic and other forces and move in the direction of opening the sewage inlet port 104 until the cleaning element 25 descends to the cleaning position and the sewage inlet valve 116 also moves to the specified position.

[0195] In some embodiments, reference Figure 3-Figure 5 as well as Fig.30 and Fig.31 The linkage may include a first rope assembly 118. Specifically, one end of the first rope assembly 118 is connected to the sewage inlet valve 116, and the other end of the first rope assembly 118 is connected to the air inlet valve 117. The housing 10 is provided with a plurality of support columns on the extension path of the first rope assembly 118, and the first rope assembly 118 is sequentially wound around the plurality of support columns. Thus, through the cooperation between the first rope assembly 118 and the plurality of support columns, it can be ensured that the force applied to the sewage inlet valve 116 and the air inlet valve 117 by the first rope assembly 118 can make the sewage inlet valve 116 and the air inlet valve 117 open or close synchronously.

[0196] In this embodiment, there is no specific limitation on the specific arrangement of the multiple support columns and the winding method of the first rope assembly 118 on the multiple support columns, and they can be flexibly arranged according to actual needs.

[0197] To facilitate the connection between the first rope assembly 118 and the sewage inlet valve 116 and the air intake valve 117, in this embodiment, the first rope assembly 118 may include: a rope body and a connector. There are two connectors, which are respectively arranged at both ends of the rope body. The shape of the connector can be flexibly set according to the force transmission requirements. The two connectors are respectively connected to the sewage inlet valve 116 and the air intake valve 117. In this way, the first rope assembly 118 can cooperate well with the sewage inlet valve 116 and the air intake valve 117, and the overall structure is relatively simple.

[0198] As shown in the above embodiment, the first rope assembly 118 may include a rope body and two connectors, which are respectively arranged at both ends of the rope body. The connectors may respectively abut against the sewage inlet valve 116 and the air inlet valve 117. During the movement of the sewage inlet valve, the sewage inlet valve 116 may drive the connector abutting therewith to move, and the connector moves, thereby driving the first rope assembly 118 to move, so that the connector abutting against the air inlet valve 117 moves, thereby driving the air inlet valve 117 to move, so that the air inlet valve 117 moves with the sewage inlet valve 116. In this way, the linkage of the cleaning element 25, the sewage inlet valve 116 and the air inlet valve 117 can be realized at the same time, avoiding the complexity of the overall structure and control logic when the driving mechanism 21 is separately configured for the sewage inlet valve 116, the air inlet valve 117 and the cleaning element 25.

[0199] like Figure 1 and Figure 2As shown, in some possible embodiments, the solid isolation assembly 20 may further include a water-gas separation structure 203, which is suitable for water-gas separation of dirt, and the water-gas separation structure 203 is also suitable for retaining solid dirt in the dirt in the first receiving chamber 103a. Specifically, the water-gas separation structure 203 separates the receiving chamber 103 into a second receiving chamber 103b and a first receiving chamber 103a, and the sewage inlet 104 is arranged in the first receiving chamber 103a. In this way, it is helpful to further simplify the structure of the receiving chamber 103 and reduce the production cost.

[0200] In some embodiments, reference Figure 1 and Figure 2 The water-gas separation structure 203 includes a plurality of blocking ribs 205, each of which includes two baffles. The connecting line of the two baffles extends along the height direction of the box body 10. The angle between the two baffles facing the first accommodating cavity 103a or the second accommodating cavity 103b is greater than 0 degree and less than 180 degrees, and a fluid channel is formed between two adjacent blocking ribs 205.

[0201] The blocking ribs 205 can be arranged on the fixed bracket 204, and the fixed bracket 204 is, for example, a square frame, and the fixed bracket 204 is fixed to the inner wall of the box body. There are multiple blocking ribs 205, and they are suitable for blocking the passage of solid dirt. The multiple blocking ribs 205 are arranged at intervals in the space surrounded by the fixed bracket 204. When dirt and air flow flow to the water-gas separation structure, the solid is isolated in the first accommodation chamber by the water-gas separation structure, and the gas and liquid can collide with the baffle, so that the speed of the liquid is less than the speed of the gas. When the baffle is set as a flat plate, the speed of the liquid can even drop to zero, so that the liquid condenses on the baffle and slides off the baffle due to gravity.

[0202] The setting mode in which the angle between the two baffles of the blocking rib and the first accommodating chamber 103a or the second accommodating chamber 103b is greater than 0 degree and less than 180 degrees can further ensure that the liquid velocity drops quickly to zero. The liquid is blocked on one side of the baffle surface, so that the liquid condenses on the baffle and slides off the baffle due to gravity, thereby increasing the gas-liquid separation effect.

[0203] Furthermore, under the above structure, sewage can exist in the first accommodating chamber 103a and the second accommodating chamber 103b at the same time, so as to improve the sewage storage capacity of the sewage tank 1 for sewage.

[0204] In some embodiments, reference Figure 2The multiple blocking ribs 205 are divided into more than two blocking rib groups, and the multiple blocking rib groups are arranged at intervals along the first direction. Each blocking rib group includes more than two blocking ribs 205, and the more than two blocking rib groups are arranged along the connecting direction between the first accommodating cavity 103a and the second accommodating cavity 103b; the more than two blocking ribs 205 in the blocking rib group are arranged along a direction perpendicular to the connecting direction.

[0205] Among them, in the first possible blocking rib group structure, the projections of the blocking ribs 205 in two adjacent blocking rib groups in the connecting direction do not completely overlap, that is, the blocking ribs 205 in two adjacent blocking rib groups are staggered so that the gas-liquid fluid flowing out from the previous blocking rib along the direction of the airflow collides with the next blocking rib, performing gas-liquid separation again, thereby improving the gas-liquid separation effect.

[0206] In the second possible barrier rib group structure, the baffle angle of the barrier rib 205 facing the first accommodating cavity 103a in one barrier rib group is less than 180 degrees, and the baffle angle of the barrier rib 205 facing the first accommodating cavity 103a in another barrier rib group is greater than 180 degrees. In this way, the barrier ribs 205 of adjacent barrier rib groups can also be arranged in a staggered manner. In this way, along the direction of the airflow, the barrier rib 205 with a baffle angle less than 180 degrees facing the first accommodating cavity 103a can increase the flow velocity difference between gas and liquid, while the barrier rib 205 with a baffle angle greater than 180 degrees facing the first accommodating cavity 103a can reduce the liquid velocity while playing a guiding role to facilitate the flow of gas.

[0207] refer to Figure 2 Each blocking rib 205 is V-shaped. Since the water-gas separator is composed of multiple rows of V-shaped ribs arranged in a staggered manner, when the air is pumped, the water vapor will collide with the V-shaped ribs for many times, and the small liquid of the water-gas mixture will adhere to the blocking rib 205 and flow to the bottom of the sewage tank 1 along the blocking rib 205, while the gas will flow to the suction port at the top of the suction chamber 108 and flow to the suction fan through the HEPA 124. In addition, the multiple rows of V-shaped blocking ribs 205 of the water-gas separator are staggered, which also blocks the larger solid waste from flowing to the suction chamber 108, and the sewage outlet 105 is arranged on the side of the first accommodating chamber 103a, so that the larger solid waste is closer to the sewage outlet 105 and is easier to be sucked away from the sewage outlet 105.

[0208] Optionally, a flow gap is provided on the bottom surface of the water-gas separator and the sewage tank 1 , and the height of the flow gap ranges from 1.5 to 3 mm, so that the tiny particles entering the suction chamber 108 can re-enter the first accommodating chamber 103a and be discharged from the sewage outlet 105 .

[0209] The air extraction chamber can also be arranged on a side close to the second accommodating chamber, the air outlet is arranged on the upper side of the second accommodating chamber, and the air extraction chamber is connected with the second accommodating chamber through the air outlet. Accordingly, the liquid outlet of the cleaning device is arranged in the second accommodating chamber, the liquid outlet direction of the cleaning device is the air flow direction from the air outlet to the sewage outlet, and / or the liquid outlet direction of the cleaning device is the direction of flowing to the bottom wall of the second accommodating chamber, so that the water flow can flow through the first accommodating chamber and the second accommodating chamber, thereby improving the cleaning effect of the entire box.

[0210] refer to Fig.21 The second accommodating chamber 103b can also be located on both sides of the first accommodating chamber 103a, and the air suction chamber 108 can be arranged on both sides of the second accommodating chamber 103b. The air suction chamber 108 is arranged on a side close to the second accommodating chamber 103b, and can also be connected with the second accommodating chamber 103b through an air port. Water can also flow through the first accommodating chamber and the second accommodating chamber to improve the cleaning effect of the entire box.

[0211] In some embodiments, in combination Figure 1 and Fig. 9 The box body 10 includes a box body 101 and a box cover 102. The box body 101 and the box cover 102 are both square. The top of the box body 101 can be open. The box cover 102 covers the top of the box body 101 and defines a receiving cavity 103 together with the box body 101. In this way, the structure of the box body 10 is relatively simple and easy to manufacture and assemble.

[0212] In some embodiments, in combination Fig.10 , Fig.11 and Fig.12 One end of the box cover 102 is pivotally connected to the box body 101, and the other end of the box body 101 is snap-fitted with the box body 101. For example, one end of the box cover 102 is provided with a pivot shaft 1021, and the other end is provided with a buckle portion 1022. One side of the box body 101 is provided with a pivot hole, and the other side is provided with a buckle hole 1011. The pivot shaft 1021 can be rotatably matched in the pivot hole, and the buckle portion 1022 is snap-fitted with the buckle hole 1011. In this way, the connection and matching method of the box body 10 is relatively simple and easy to implement.

[0213] In some possible embodiments, a sealing gasket is embedded on the side of the box cover 102 facing the accommodating cavity 103, and a sealing rib is provided on the upper edge of the box body 101. The height of the sealing rib is 0.5 mm, and the sealing rib abuts against the sealing gasket, thereby effectively ensuring the sealing of the box body 10 and preventing sewage from overflowing when traversing obstacles or being manually flipped.

[0214] Optionally, refer to Fig.19A sensor bracket 123 may be provided on the inner side of the box cover 102. The sensor bracket 123 is used to install a liquid level sensor. The liquid level sensor may be used to detect the liquid level in the sewage tank 1. When the amount of waste in the sewage tank 1 reaches a set capacity, the liquid level sensor communicates with the control device of the cleaning device 100, so that the control device promptly controls the cleaning device 100 to return to the base station, remove the waste, and self-clean the sewage tank 1, so as to prevent the sewage tank 1 from being overfilled with waste and overflowing.

[0215] In some embodiments, in combination Figure 6 and Figure 7 , a sewage valve is provided at the sewage outlet 105, and the box body 10 also includes a limiting device 60, which may include a handle 61 and a limiting rod 62. Specifically, the handle 61 is in a rod shape, and the first end of the handle 61 is rotatably connected to the side wall of the box cover 102, and a transmission tooth is provided on the circumference of the first end of the handle 61. The limiting rod 62 is movably provided on the box cover 102, and the limiting rod 62 is provided with a meshing tooth, and the transmission tooth meshes with the meshing tooth. When the handle 61 rotates, the limiting rod 62 is driven to move between a first position and a second position, wherein, in the first position, the limiting rod 62 abuts against the sewage valve to apply a force to the sewage valve to close the sewage outlet 105, and in the second position, the limiting rod 62 is separated from the sewage valve. In this way, when the handle 61 is flattened, the limiting rod 62 can be pushed out and the sewage valve is pressed tightly, so that the sealing at the sewage valve is better. When the handle 61 is lifted, the limiting rod 62 is pushed to retract inward, and the sewage tank 1 can be easily lifted out.

[0216] In addition to the above-mentioned arrangement, the overall shape of the sewage tank 1, the first accommodating chamber 103a, the second accommodating chamber 103b, the air extraction chamber 108 and the layout of the cleaning device 40 inside the sewage tank 1 can be adjusted according to actual needs.

[0217] like Figure 20-27 As shown, this embodiment also provides another layout of the sewage tank 1. Fig.21 The first accommodating chamber 103a is arranged in the middle of the box body 10, wherein the sewage inlet 104 is located at the top of the first accommodating chamber 103a, and there are two second accommodating chambers 103b, which are respectively located on the opposite sides of the first accommodating chamber 103a along the first direction. Each second accommodating chamber 103b is separated from the first accommodating chamber 103a by a first partition plate 201. The first partition plate 201 can be constructed as a coarse filter plate, which is convenient for intercepting larger solid dirt in the first accommodating chamber 103a, and is convenient for the later recovery of large garbage. Sewage and smaller solid dirt can flow from the coarse filter plate to the second accommodating chambers 103b on both sides, ensuring a larger garbage carrying capacity of the sewage tank 1.

[0218] There are also two air extraction chambers 108, and each air extraction chamber 108 is located on the side of the corresponding second accommodating chamber 103b away from the first accommodating chamber 103a along the first direction. The sewage chamber 112 is located in the first accommodating chamber 103a, and the part of the sewage chamber 112 located in the first accommodating chamber 103a extends in the vertical direction. The bottom end of the sewage chamber 112 is the sewage inlet 113, and the rest of the sewage chamber 112 is located at the top of the box body 10 and extends in the horizontal direction. The other end of the sewage chamber 112 in the horizontal direction is the sewage outlet 105. Each suction cavity 108 is separated from the second accommodation cavity 103b by an air baffle, and the bottom end of the air baffle is spaced from the bottom wall of the box body 10 to form a flow gap. The cleaning device 40 may include two liquid inlet pipes 403, which are respectively arranged at the corresponding suction cavity 108, and the liquid outlet 404 of the liquid inlet pipe 403 faces the bottom wall of the suction cavity 108, so as to ensure that the cleaning liquid and airflow entering the suction cavity 108 flow from both sides to the middle along the bottom wall of the sewage tank 1, and push the garbage to the vicinity of the first accommodation cavity 103a as much as possible. The bottom wall of the sewage tank 1 is a structure with a low middle and high sides, so that the sewage and garbage can flow to the middle position more easily.

[0219] Further, refer to Fig. 22 and Fig.23 , a duckbill valve 125 is provided inside the sewage outlet 105, for example, the duckbill valve 125 is provided in the sewage chamber 112. The duckbill valve 125 can be constructed to be closed when the cleaning device 100 sucks sewage through negative pressure, and to be opened when the sewage tank 1 discharges sewage. Optionally, the duckbill valve 125 can be one or more. When the cleaning device 100 performs a cleaning task, since it is necessary to absorb dirt through negative pressure, the internal pressure of the duckbill valve 125 is low and the external pressure is high, so that it is in a closed state, thereby ensuring the vacuum degree of the sewage tank 1 when the cleaning device 100 is working, and effectively ensuring the suction force. When discharging sewage, the internal pressure of the sewage tank 1 is high and the external pressure is low, and the duckbill valve 125 will open, and then the dirt in the sewage tank 1 can be smoothly discharged into the base station. Of course, the utility model is not limited to this, and the duckbill valve 125 provided in this embodiment can also be replaced by other one-way valves.

[0220] Further, refer to Figure 24-Figure 27 The box body 10 includes a box body 101 and a box cover 102. The cleaning device 40 may also include a third liquid supply channel 120. The third liquid supply channel 120 is arranged inside the box cover 102. The bottom wall of the third liquid supply channel 120 is provided with a plurality of spray ports 121, and the spray ports 121 are connected to the accommodating chamber 103.

[0221] In other words, the cleaning device 40 of the sewage tank 1 may also adopt a top spray structure. The third liquid supply channel 120 may extend along the circumference of the top cover. In this case, the spray port 121 of the cleaning liquid is arranged on the inner circumference of the tank cover 102, such as Fig.25 As shown, the size of the spray port 121 should be as small as possible so that the cleaning liquid forms a jet, increases the impact force, and improves the spray effect. Of course, the third liquid supply channel 120 may include multiple liquid separation channels, and the multiple liquid separation channels are all connected to the water inlet of the third liquid supply channel 120. The distribution of the liquid separation channels is as follows: Fig.26 As shown, the cleaning liquid is diverted from the water inlet to the liquid diversion channel on the peripheral side, and the liquid diversion channel can also be gradually narrowed to ensure the flow rate of each channel. Optionally, the liquid diversion channel can be diverted by an impeller 122, such as Fig. 27 As shown, the cleaning liquid impacts the impeller 122 to rotate, thereby driving the cleaning liquid to be quickly and evenly distributed along each liquid distribution channel, thereby ensuring the flow rate of each channel.

[0222] Of course, in other embodiments, the third liquid supply channel 120 may also directly adopt a jet structure, that is, a plurality of jet ports are distributed on the bottom and side surfaces of the third liquid supply channel 120 to spray the entire area of ​​the sewage tank 1 to achieve spray cleaning of the sewage tank 1.

[0223] Optionally, the cleaning device 40 of this embodiment can clean only the first accommodating chamber 103a, or only the second accommodating chamber 103b. The first accommodating chamber 103a and the second accommodating chamber 103b are not isolated from each other, but are isolated by an air cavity and a sewage cavity 112.

[0224] The cleaning device 100 according to the second embodiment of the present invention is described below.

[0225] The cleaning device 100 of this embodiment may be a sweeping and mopping machine, a floor scrubber, or other cleaning devices 100. The cleaning device 100 includes a device body 2 and the sewage tank 1 in the above embodiment.

[0226] Among them, the equipment body 2 is suitable for walking along the surface to be cleaned and cleaning the surface to be cleaned, and the sewage tank 1 is arranged on the equipment body 2. When the equipment body 2 cleans the surface to be cleaned, the sewage tank 1 can collect dirt, that is, the dirt can enter the containing chamber 103 through the sewage inlet 104 under the action of negative pressure, and the solid dirt can be in the first containing chamber 103a, and the sewage can be in the second containing chamber 103b.

[0227] According to the cleaning device 100 of the embodiment of the utility model, by setting the sewage tank 1 in the above embodiment, blockage can be prevented during sewage discharge, and it is beneficial to reduce odor generation and improve user experience. In addition, it can effectively prevent sewage overflow when the cleaning device 100 overcomes obstacles or is manually turned over.

[0228] The cleaning device 100 of the third embodiment of the utility model is described below. The cleaning device 100 includes a housing 10, a linkage mechanism, and a cleaning element 25; the housing 10 includes a accommodating chamber 103, and the accommodating chamber 103 is used to accommodate dirt sucked from the outside of the housing 10; the housing 10 is provided with a sewage inlet 104 and an air suction port, and the air suction port is connected to the air suction fan of the cleaning device 100, the sewage inlet 104 is used to suck dirt from the outside of the housing 10 under the negative pressure of the air suction fan, and the air suction port is used to discharge the airflow in the housing 10 out of the housing under the negative pressure of the air suction fan. 10; a sewage inlet valve 116 is provided at the sewage inlet 104, and the sewage inlet valve 116 is used to open and close the sewage inlet 104; an air intake valve 117 is provided at the air extraction port, and the air intake valve 117 is used to open and close the air intake valve 117; the linkage mechanism is respectively connected to the sewage inlet valve 116, the air intake valve 117 and the cleaning element 25, and during the lifting process of the cleaning element 25, the sewage inlet valve 116 and the air intake valve 117 are driven to move through the linkage mechanism to open or close the sewage inlet 104 and the air extraction port, respectively.

[0229] The box body 10 can be a sewage box 1 or a dust box, which is not limited here. The sewage box 1 can adopt a structure that does not involve solid isolation or a structure that involves solid isolation, which is not limited here. Of course, the sewage box 1 structure provided in the above embodiment can also be combined in this embodiment.

[0230] Based on the linkage mechanism, when the cleaning element 25 rises, the sewage inlet valve 116 and the air inlet valve 117 are synchronously driven to move, and the sewage inlet port 104 and the air extraction port are closed, so that the sewage in the sewage tank 1 is more effectively prevented from leaking out of the sewage tank 1 during the obstacle crossing process of the cleaning device 100. When the cleaning element 25 descends, the sewage inlet valve 116 and the air inlet valve 117 can be synchronously driven to move, and the sewage inlet port 104 and the air extraction port can be opened to perform cleaning.

[0231] At the same time, the movement of the sewage inlet valve 116, the air intake valve 117 and the cleaning element 25 of the cleaning device 100 can be synchronously controlled through the same driving mechanism 21, and it is also possible to eliminate the need to configure corresponding driving mechanisms 21 for the sewage inlet valve 116 and the air intake valve 117, which is conducive to simplifying the overall structure and control logic, and takes up less space.
