[0022] The present application describes a cleaning device that can be used in daily cleaning work and can clean a surface to be cleaned, such as particles, threads, debris, strips, flakes, liquids, stains, and other garbage that affect the cleaning of the surface to be cleaned. Specifically, based on the design requirements of the cleaning device, the cleaning device can clean garbage corresponding to the design requirements.

[0023] The surface to be cleaned may be on the ground, on stairs, on the floor, on a table, or on any other structure that may contain garbage and may need to be cleaned, which will not be described in detail.

[0024] See also Figure 1 , Figure 1 Schematic diagram of the structure of the cleaning device in some embodiments of the present application. The cleaning device 100 may have a working mode. In the working mode, the cleaning device 100 can be used to clean the surface to be cleaned and remove the garbage on the surface to be cleaned. Of course, the cleaning device 100 may also have a self-cleaning mode. In the self-cleaning mode, the cleaning device 100 can clean and clean the garbage accumulated on part of its structure in the working mode.

[0025] See also Figure 1, the cleaning device 100 may be a handheld floor scrubber and may include a cleaning body 101 and a handheld portion 102. The cleaning body 101 may serve as the main body of the cleaning device 100 for cleaning the surface to be cleaned. The handheld portion 102 may be connected to the cleaning body 101. The handheld portion 102 may be held by a user. The user may control the cleaning body 101 through the handheld portion 102 to clean and / or move. In some embodiments, the cleaning body 101 and the handheld portion 102 may cooperate to accommodate liquid, batteries, processors, control panels and / or control buttons for cleaning, etc.

[0026] In other embodiments, the cleaning device 100 may also be a floor-cleaning robot, which only includes the cleaning body 101 , which is not limited here.

[0027] exist Figure 1 In the embodiment, the user can hold the handheld portion 102 to control the cleaning body 101 to move in the front-to-back direction (which can be referred to as the traveling direction), such as moving forward, moving backward, or moving back and forth. Of course, the cleaning body 101 can also be controlled to move in a turning direction.

[0028] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0029] In some embodiments, the handheld portion 102 may be omitted, and the cleaning body 101 may be cleaned and / or moved under intelligent control.

[0030] See also Figure 2 and Figure 3 , Figure 2 for Figure 1 The schematic diagram of the structure of the cleaning body 101 in some embodiments shown in the embodiment, Figure 3 for Figure 2 The cleaning device 100 may include a cleaning body 101. The cleaning body 101 may include a main frame 10, a cleaning module 20, a storage box 40 and a liquid level adjustment control 50 (see attached Figure 4 , Figure 4 for Figure 3 The storage box 40 and the liquid level control unit 50 in the embodiment shown in the figure are matched in some embodiments. The cleaning module 20, the storage box 40 and the liquid level control unit 50 can be installed on the main frame 10. The cleaning module 20 can be used to clean the garbage on the surface to be cleaned, and can transport the garbage to the storage box 40 in cooperation with the main frame 10. The storage box 40 can collect and store the garbage.

[0031] In some embodiments, the storage box 40 includes a collection chamber 402 and a storage chamber 403 that are spaced apart. The collection chamber 402 is used to receive garbage and liquid dropped from the drop opening 1004. The collection chamber 402 and the storage chamber 403 are connected through a communication port 404 (such as Figure 4 and Figure 5 The liquid level adjustment control 50 is connected to the storage chamber 403; the liquid in the collection chamber 402 can flow into the storage chamber 403 through the communication port 404, and the liquid level adjustment control 50 is used to adjust the gas pressure in the storage chamber 403 to prevent the liquid in the storage chamber 403 from flowing back into the collection chamber 402 through the communication port 404, so that the liquid is stored in the storage chamber 403 as much as possible, thereby improving the phenomenon of liquid gushing out of the storage box 40. In some scenarios, the liquid is stored in the storage chamber 403 as much as possible, and then the liquid level in the storage chamber 403 will be higher than the liquid level in the collection chamber 402, thereby improving the storage capacity of the storage box 40. In some scenarios, the collection chamber 402 and the storage chamber 403 are arranged at intervals in the direction of travel, and when the liquid in the collection chamber 402 surges, the liquid in the storage chamber 403 is blocked from flowing into the collection chamber 402 from the communication port 404, and only the liquid in the collection chamber 402 surges, thereby improving the phenomenon of liquid gushing out of the storage box 40.

[0032] It can be understood that the garbage stored in the storage box 40 may include liquid stored in the cleaning device 100 and used for cleaning and / or liquid collected from the surface to be cleaned.

[0033] In other embodiments, the cleaning device 100, such as the cleaning body 101, may further include a scraper 30. The scraper 30 may be mounted on the main frame 10. The scraper 30 may clean the garbage on the cleaning module 20, so that the garbage falls off the cleaning module 20 and is further transported to the storage box 40. In some scenarios, the liquid may be scraped and squeezed by the scraper 30 and separated from the cleaning module 20 and enter the storage box 40.

[0034] The main frame 10 may include a base 11, a flip cover 12 and a wheel body 13. The flip cover 12 and the wheel body 13 may be disposed on the base 11. The base 11 may form an installation cavity 1001 for installing the cleaning module 20, the scraper 30, the storage box 40 and the liquid level adjustment control 50. The flip cover 12 is connected to the base 11. The wheel body 13 may enable the base 11 to move on the surface to be cleaned.

[0035] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0036] The base 11 can be a shell structure or a frame structure, or other structures, which will not be described in detail here. Figure 2 , Figure 3 and Figure 5 , Figure 5 for Figure 2 In the embodiment shown, the cleaning body 101 is a schematic cross-sectional view at line V-V, and the base 11 is provided with a conveying portion 14 inside the mounting cavity 1001. The conveying portion 14 can cooperate with the cleaning module 20 to pick up and / or transport garbage. In some embodiments, the conveying portion 14 can scrape the surface to be cleaned to collect garbage. In some embodiments, the conveying portion 14 can cooperate with the cleaning module 20 to pick up garbage on the surface to be cleaned. In some embodiments, the conveying portion 14 can cooperate with the cleaning module 20 to transport garbage to the storage box 40.

[0037] The conveying part 14 can divide the installation cavity 1001 into a placement cavity 1002 and a receiving cavity 1003. The placement cavity 1002 is located at the front side of the conveying part 14 and is used to receive the cleaning module 20. The receiving cavity 1003 is located at the rear side of the conveying part 14 and is used to receive the storage box 40. The conveying part 14 can cooperate with the cleaning module 20 to transport the garbage from the placement cavity 1002 to the receiving cavity 1003.

[0038] A conveying surface 141 is disposed at the front side of the conveying portion 14 . The conveying surface 141 can cooperate with the cleaning module 20 so that garbage can be transported from the lower end of the conveying surface 141 to the upper end of the conveying surface 141 .

[0039] The upper end of the conveying surface 141 is further back than the lower end of the conveying surface 141, and the lower end of the conveying surface 141 is further forward than the upper end of the conveying surface 141. The combination of the slope of the conveying surface 141 and the parameters of the upper end of the conveying surface 141 can ensure that the cleaning body 101 meets the garbage conveying capacity while ensuring the conveying height of the garbage, so that the storage box 40 has a deeper garbage cavity.

[0040] The base 11 is provided with a drop opening 1004. The drop opening 1004 is provided near the upper end of the conveying surface 141 and can communicate with the placement cavity 1002 and the accommodating cavity 1003, so that when the garbage is located at the upper end of the conveying surface 141, it can fall from the drop opening 1004 into the storage box 40 in the accommodating cavity 1003. That is, the accommodating cavity 1003 can be at least partially located at the rear side of the conveying surface 141.

[0041] See also Figure 2 , Figure 3 and Figure 5 The base 11 may be provided with an introduction portion 15 at the bottom of the conveying portion 14. The introduction portion 15 is located on one side of the conveying surface 141 extending toward the surface to be cleaned. In some embodiments, the introduction portion 15 may contact the surface to be cleaned, or may be slightly spaced from the surface to be cleaned.

[0042] The introduction portion 15 can be used to perform at least one of the following functions: scraping the garbage on the surface to be cleaned, picking up the garbage on the surface to be cleaned in cooperation with the cleaning module 20 , and transferring the garbage to the transfer surface 141 in cooperation with the cleaning module 20 .

[0043] The introduction part 15 can be arranged near the lower end of the conveying surface 141, and the surface of the introduction part 15 cooperating with the cleaning module 20 can be transitionally connected with the conveying surface 141. The introduction part 15 can cooperate with the cleaning module 20 to clean the garbage on the surface to be cleaned, and can transport the garbage to the conveying surface 141.

[0044] When the cleaning body 101 cleans the surface to be cleaned, the introduction part 15 scrapes the garbage on the surface to be cleaned, or gathers the garbage together. The introduction part 15 cooperates with the cleaning module 20 to pick up the garbage on the surface to be cleaned, and can transport the garbage to the conveying surface 141.

[0045] In some embodiments, when the delivery portion 14 can realize at least part of the capabilities of the introduction portion 15 , the introduction portion 15 may be omitted.

[0046] See also Figure 2 , Figure 3 and Figure 5 The flip cover 12 can be used to inspect, assemble and clean the cleaning body 101. The flip cover 12 can be connected to the base 11 at the front side of the base 11 by screwing, welding, bonding, rotating connection, card connection or plug connection.

[0047] The front side of the base 11 may form an assembly opening, and the flip cover 12 may be disposed on the assembly opening to cover the assembly opening. The assembly opening may be communicated with the placement cavity 1002 .

[0048] See also Figure 2 , the wheel body 13 can be arranged on the base 11. The wheel body 13 can roll, thereby realizing the movement of the cleaning body 101. In some embodiments, a motor can be arranged in the cleaning body 101 to drive the wheel body 13 to rotate.

[0049] The wheel body 13 can be arranged to form a support plane PL (such as Figure 5 As shown in the figure, the cleaning body 101 is supported on the surface to be cleaned by the wheel body 13. The number of the wheel body 13 can be one or more, and of course, it can also include at least three. In some embodiments, the forward direction of the wheel body 13 can be the traveling direction. In some embodiments, the wheel body 13 can form a support plane PL with the cooperation of the cleaning module 20. That is, the wheel body 13 can cooperate with the cleaning module 20 to form a support plane PL.

[0050] See also Figure 2 , Figure 3 and Figure 5The cleaning module 20 can be mounted on the base 11 and can be against the front side of the introduction portion 15 and / or the conveying surface 141. The cleaning module 20 can extend from the placement cavity 1002 from the assembly port to contact the surface to be cleaned to achieve garbage cleaning.

[0051] See also Figure 3 and Figure 5 The cleaning module 20 may include a first roller 21, a second roller 22, a connecting rod assembly 23 and a cleaning belt 24. One end of the first roller 21 and the connecting rod assembly 23 are rotatably supported on the base 11, and the second roller 22 is supported on the other end of the connecting rod assembly 23. The cleaning belt 24 is annularly arranged around the periphery of the first roller 21 and the second roller 22. When the first roller 21 and / or the second roller 22 rotates, the cleaning belt 24 is driven to rotate.

[0052] It is understood that the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0053] The first roller 21 may be rotatably connected to the base 11. In some embodiments, the first roller 21 may be disposed adjacent to the upper end of the conveying surface 141. In some embodiments, the first roller 21 may be located above the drop opening 1004.

[0054] The connecting rod assembly 23 can be rotatably connected to the base 11. It can be understood that when the connecting rod assembly 23 is rotatably connected to the base 11, the connecting rod assembly 23 can be made to swing when rotating.

[0055] In some embodiments, a motor may be provided in the connecting rod assembly 23, and the motor may be in transmission connection with the first roller 21 and / or the second roller 22, so as to drive the first roller 21 and / or the second roller 22 to rotate, thereby driving the cleaning belt 24 to rotate. In some embodiments, the motor may be provided on the base 11.

[0056] In some embodiments, the connecting rod assembly 23 may not be rotatably connected to the base 11, but may be rotatably connected to the first roller 21, so as to be indirectly rotatably connected to the base 11 through the first roller 21. In some embodiments, the first roller 21 may not be rotatably connected to the base 11, but may be rotatably connected to the connecting rod assembly 23, so as to be indirectly rotatably connected to the base 11 through the connecting rod assembly 23.

[0057] In some embodiments, the first roller 21 and the connecting rod assembly 23 can both rotate around a first axis. In some embodiments, the first roller 21 can rotate around the first axis, and the connecting rod assembly 23 can rotate around a second axis. The second axis is parallel to the first axis.

[0058] In some embodiments, the second axis may be coaxial with the first axis or may be non-coaxial with the first axis, that is, the second axis and the first axis are on the same line.

[0059] The second roller 22 can be rotatably connected to the connecting rod assembly 23 and can rotate around a third axis. In some embodiments, the third axis is arranged parallel to the first axis. In some embodiments, the second roller 22 is arranged adjacent to the lower end of the conveying surface 141. In some embodiments, the second roller 22 can cooperate with the wheel body 13 to form a support plane PL.

[0060] The cleaning belt 24 may abut against the front side of the introduction portion 15 and / or the conveying surface 141 , or may abut against the surface to be cleaned.

[0061] When the cleaning belt 24 rotates, it can clean the garbage on the surface to be cleaned, and can cooperate with the introduction part 15 to clean and pick up the garbage on the surface to be cleaned, and can transport the garbage to the conveying surface 141. The cleaning belt 24 cooperates with the conveying surface 141 to transport the garbage from the lower end of the conveying surface 141 to the upper end of the conveying surface 141, and further transport it to the storage box 40.

[0062] The cleaning belt 24 can be pressed against the surface to be cleaned by the second roller 22 to increase the pressure between the cleaning belt 24 and the surface to be cleaned and improve the cleaning effect. In some embodiments, when the cleaning body 101 is placed on the surface to be cleaned, the connecting rod assembly 23 can swing to support the cleaning module 20 as much as possible from the surface to be cleaned, so that the second roller 22 presses the cleaning belt 24 against the surface to be cleaned. In some embodiments, when the cleaning body 101 cleans the garbage on the surface to be cleaned, it will come into contact with the garbage and can be supported by the garbage, and then it can swing through the connecting rod assembly 23 to achieve the lifting of the second roller 22 and the cleaning belt 24, passing over the garbage on the surface to be cleaned. The cleaning belt 24 can be made of a water-absorbing material. Of course, in order to improve the cleaning effect, the cleaning belt 24 can also be provided with a multi-layer structure.

[0063] In some embodiments, the first roller 21 can be omitted, the connecting rod assembly 23 is rotatably connected to the base 11, and the cleaning belt 24 is only wound on the second roller 22 to form a cleaning roller. By adjusting the slope of the conveying surface 141 of the conveying portion 14 and the distance between the upper end and the lower end, the cleaning roller can be in contact with the surface to be cleaned and the conveying surface 141, and can be close to the drop port 1004. The cleaning roller can clean the garbage on the surface to be cleaned, and can be transported in cooperation with the conveying surface 141, and enter the garbage into the storage box 40 through the drop port 1004. Further in some scenarios, the scraper 30 can clean the garbage on the cleaning roller. Further in some scenarios, the connecting rod assembly 23 can also be omitted, and the second roller 22 is directly rotatably connected to the base 11.

[0064] In some embodiments, the cleaning module 20 may also be other common cleaning structures, which are not limited here.

[0065] See also Figure 3 and Figure 5 The scraper 30 can be disposed on the base 11 to press against the cleaning belt 24 to clean the garbage on the cleaning belt 24 so that the garbage falls off.

[0066] The scraper 30 may be disposed above the drop opening 1004 and may abut the cleaning belt 24 against the outer circumference of the first roller 21. The scraper 30 may clean the garbage on the cleaning belt 24, causing the garbage to fall and enter the accommodating chamber 1003 from the drop opening 1004.

[0067] The scraper 30 may be disposed at the rear side of the cleaning belt 24. In some embodiments, the scraper 30 may be used to clean the garbage on the cleaning belt 24 in a working mode or a self-cleaning mode.

[0068] See also Figure 3 and Figure 5 The storage box 40 can be partially placed in the accommodating cavity 1003 to accommodate garbage. When the garbage enters from the drop opening 1004, it can directly fall into the accommodating cavity 401 of the storage box 40. Of course, the storage box 40 can also be completely placed in the accommodating cavity 1003.

[0069] The storage box 40 may have a box opening 4001 , so that the garbage entering from the drop opening 1004 passes through the box opening 4001 and falls into the accommodating cavity 401 of the storage box 40 .

[0070] The rear side of the base 11 may form a placement opening, which may be connected to the accommodating cavity 1003. The storage box 40 may extend into the accommodating cavity 1003 from the placement opening, and the box opening 4001 and the drop opening 1004 may be relatively connected to form a garbage conveying channel.

[0071] In some embodiments, the lowermost end 4002 of the edge of the box opening 4001 may be located at the rear side of the upper end of the conveying surface 141 .

[0072] In some embodiments, the storage box 40 can be connected to the base 11 by screwing, welding, bonding, rotational connection, snap connection or plug-in connection.

[0073] In some embodiments, the storage box 40 may also be a part of the main frame 10. In some embodiments, the storage box 40 is a part of the base 11, and the accommodating cavity 1003 is formed in the storage box 40, that is, the accommodating cavity 401 may also be referred to as the accommodating cavity 1003. In some embodiments, the storage box 40 and the base 11 are an integrally formed structure.

[0074] See also Figure 5 , Figure 6 and Figure 7 , Figure 6 for Figure 5 The schematic diagram of the structure of the storage box 40 in some embodiments shown in the embodiment, Figure 7 for Figure 6 The storage box 40 in the embodiment shown is an exploded view of some embodiments. The storage box 40 may include a box body 41 and a partition wall 42. The box body 41 is provided with a box opening 4001 and a receiving chamber 401. The partition wall 42 can divide the receiving chamber 401 into a collecting chamber 402 and a storage chamber 403. The box opening 4001 is connected to the collecting chamber 402, and the collecting chamber 402 and the storage chamber 403 are connected through a connecting opening 404 (such as Figure 4 and Figure 5 shown) connected.

[0075] In some scenarios, the collecting chamber 402 and the storage chamber 403 are spaced apart in the direction of travel, and liquid can enter the containing chamber 401 from the box mouth 4001 and be stored in the collecting chamber 402. Liquid can flow from the collecting chamber 402 into the storage chamber 403 through the connecting port 404. The collecting chamber 402 and the storage chamber 403 are spaced apart, so compared with the liquid in the entire containing chamber 401, the liquid in the collecting chamber 402 is less. When the cleaning device 100 moves back and forth, the liquid in the storage chamber 403 will be blocked by the partition wall 42 when it surges due to inertia. Only the liquid in the collecting chamber 402 has the opportunity to surge out of the storage box 40 due to inertia. Compared with the solution that does not divide the containing chamber 401 into the collecting chamber 402 and the storage chamber 403, the solution that the collecting chamber 402 and the storage chamber 403 are spaced apart will improve the phenomenon of liquid surging out of the storage box 40.

[0076] In some scenarios, liquid can enter the receiving chamber 401 from the box opening 4001 and be stored in the collecting chamber 402. Liquid can flow from the collecting chamber 402 into the storage chamber 403 through the connecting port 404. The liquid level adjustment control 50 can adjust the gas pressure in the storage chamber 403 to prevent the liquid in the storage chamber 403 from flowing back into the collecting chamber 402 through the connecting port 404, so that the liquid is stored in the storage chamber 403 as much as possible. In some scenarios, the liquid is stored in the storage chamber 403 as much as possible, and then the liquid level in the storage chamber 403 will be higher than the liquid level in the collecting chamber 402, thereby improving the storage capacity of the storage box 40. In some scenarios, the collecting chamber 402 and the storage chamber 403 are arranged at intervals in the direction of travel, and when the liquid in the collecting chamber 402 surges, the liquid in the storage chamber 403 is blocked from flowing into the collecting chamber 402 from the connecting port 404, and only the liquid in the collecting chamber 402 surges, thereby improving the phenomenon of liquid surging out of the storage box 40.

[0077] The box body 41 may include a bottom wall 411, a first side wall 412, a second side wall 413, a third side wall 414, a fourth side wall 415, and a top wall 416. The first side wall 412, the third side wall 414, the second side wall 413, and the fourth side wall 415 may be connected in sequence, and may all be connected to the bottom wall 411, and may all be connected to the top wall 416, so as to form the box body 41 and the accommodating cavity 401. Among them, the first side wall 412 and the second side wall 413 are arranged oppositely, the third side wall 414 and the fourth side wall 415 are arranged oppositely, and the bottom wall 411 and the top wall 416 are arranged oppositely.

[0078] In some embodiments, the first side wall 412, the partition wall 42, and the second side wall 413 may be spaced apart along the traveling direction, so that the bottom wall 411, the first side wall 412, the third side wall 414, the fourth side wall 415, the top wall 416, and the partition wall 42 may be arranged to enclose the collection chamber 402, and the bottom wall 411, the second side wall 413, the third side wall 414, the fourth side wall 415, the top wall 416, and the partition wall 42 may be arranged to enclose the storage chamber 403. Of course, the formation of the collection chamber 402 and the storage chamber 403 is affected by the arrangement of the partition wall 42, but as long as the collection chamber 402 and the storage chamber 403 are spaced apart in a direction parallel to the support plane PL, the specific arrangement of the partition wall 42 may not be limited, nor is it limited by the embodiments listed here.

[0079] In some embodiments, the fourth side wall 415 can be detachably connected to the bottom wall 411, the first side wall 412, the second side wall 413 and the top wall 416. For example, the bottom wall 411, the first side wall 412, the second side wall 413 and the top wall 416 are connected to form a mounting opening at the connection of the fourth side wall 415, and the fourth side wall 415 can be used to block the mounting opening. Furthermore, the fourth side wall 415 can be called a "side end cover". In some embodiments, the fourth side wall 415 is inserted at the mounting opening, and of course, the detachable connection can also be achieved by other methods such as snap connection, plug connection or screw connection.

[0080] Optionally, when the fourth side wall 415 adopts a detachable connection design, it is convenient to clean the entire storage box 40.

[0081] See also Figure 7 The fourth side wall 415 is provided with a holding space 4101 on a side facing away from the third side wall 414 , so that a user can reach into the holding space 4101 and hold the fourth side wall 415 .

[0082] See also Figure 8 , Figure 8 for Figure 7Schematic diagram of the structure of the fourth side wall 415 in some embodiments. The fourth side wall 415 is provided with a first plug-in portion 4151 on the side facing the third side wall 414, so as to be plugged and fixed with the partition wall 42, reinforce the partition wall 42, and maintain the stability of the partition wall 42. In some embodiments, a groove is provided on the first plug-in portion 4151, so as to be plugged and fixed with the partition wall 42.

[0083] See also Fig. 9 , Fig. 9 for Figure 7 The schematic diagram of the partial structure of the box body 41 in some embodiments of the embodiment shown. The partition wall 42 can be connected to the top wall 416, and of course it can also be connected to the bottom wall 411. Furthermore, the partition wall 42 can also be connected to the third side wall 414 and the fourth side wall 415. In some embodiments, a second plug-in portion 421 is provided on the partition wall 42 to be plugged and fixed with the first plug-in portion 4151 to achieve the connection and fixation of the partition wall 42 and the fourth side wall 415. In some embodiments, the second plug-in portion 421 is a plug-in board so as to extend into the groove on the first plug-in portion 4151 to achieve the plug-in and fixation of the fourth side wall 415 and the partition wall 42. It can be understood that the plug-in and fixation method of the first plug-in portion 4151 and the second plug-in portion 421 is the matching method of the groove and the plug-in board, and of course other matching methods known to those skilled in the art can also be used for plug-in and fixation.

[0084] In some embodiments, the second plug-in portion 421 may connect the bottom wall 411 and the top wall 416 to reinforce the partition wall 42 and maintain the stability of the partition wall 42 .

[0085] In some embodiments, the partition wall 42 may be directly rigidly connected and fixed to the top wall 416 , the bottom wall 411 , the third side wall 414 , and the fourth side wall 415 .

[0086] See also Figure 6 , a connection port 4003 may be provided on the top wall 416 to cooperate with the liquid level control unit 50. In some embodiments, the connection port 4003 may be provided at a position of the top wall 416 corresponding to the storage cavity 403 to communicate with the storage cavity 403. In some embodiments, the connection port 4003 may not be limited to being provided on the top wall 416, but may also be provided at other positions on the box body 41 corresponding to the storage cavity 403 to communicate with the storage cavity 403, so that the liquid level control unit 50 may regulate the gas pressure in the storage cavity 403 to prevent the liquid in the storage cavity 403 from flowing back into the collection cavity 402 through the connection port 404. In some embodiments, the number of the connection ports 4003 may be multiple, and is not limited to one.

[0087] See also Figure 5 and Fig.10 , Fig.10 for Figure 5The embodiment shown is a schematic diagram of the structure of the box body 41 in some embodiments. The partition wall 42 can be spaced apart from the bottom wall 411 to form a communication port 404. It can be understood that in other embodiments, the communication port 404 can also be set on the partition wall 42 (such as Fig.11 As shown), it can of course also be set on the bottom wall 411.

[0088] In an optional embodiment, the partition wall 42 is entirely spaced apart from the bottom wall 411 , so that the length of the connecting hole 404 is consistent with that of the partition wall 42 .

[0089] In an optional embodiment, part of the partition wall 42 is spaced apart from the bottom wall 411 , and another part is directly connected to / abutted against the bottom wall 411 , so that the length of the through hole 404 thereof is smaller than that of the partition wall 42 .

[0090] See also Fig.11 , Fig.11 for Fig.10 The schematic diagram of the structure of the partition wall 42 in some embodiments shown in the embodiment. The communication port 404 can be set on the partition wall 42. And the communication port 404 can include multiple sub-ports 4041. It can be understood that when the aperture of the sub-port 4041 is small enough, it can play a role in filtering the liquid, so that the solid waste remains in the collection chamber 402, so as to prevent the liquid from surging through the solid waste. Of course, the portion of the partition wall 42 corresponding to the multiple sub-ports 4041 can form a filter portion.

[0091] See also Figure 4 The liquid level adjustment control 50 can be connected to the storage cavity 403 of the storage box 40, and the gas pressure in the storage cavity 403 can be adjusted to prevent the liquid in the storage cavity 403 from flowing back into the collection cavity 402 through the connecting port 404. Specifically, the liquid level adjustment control 50 can be directly installed at the connecting port 4003, or can be connected to the connecting port 4003 through a pipeline. Of course, the connection can also be achieved in other ways.

[0092] In some scenarios, the liquid level adjustment control 50 can control the liquid level in the storage chamber 403 to be higher than the liquid level in the collection chamber 402 .

[0093] In some scenarios, the liquid level adjustment control 50 can control the liquid level in the storage chamber 403 to be flush with the liquid level in the collection chamber 402 .

[0094] In some scenarios, the liquid level in the collection chamber 402 is higher than the uppermost end 4042 of the edge of the communication port 404 (e.g. Fig.10), the liquid level adjustment control 50 can control the liquid level in the storage chamber 403 to be flush with the liquid level in the collection chamber 402. Further, the liquid level in the storage chamber 403 can be higher than the uppermost end 4042 of the rim of the connecting port 404. Further, the liquid level in the storage chamber 403 can be higher than the uppermost end 4042 of the rim of the connecting port 404, and flush with the liquid level in the collection chamber 402. Further, the liquid level in the storage chamber 403 can be higher than the uppermost end 4042 of the rim of the connecting port 404, and higher than the liquid level in the collection chamber 402. In some embodiments, the uppermost end 4042 of the rim can be the lower end 4222 of the guide portion 422. In some embodiments, as Fig.11 As shown, the uppermost end 4042 of the rim may be the uppermost end of the rim of the sub-opening 4041 located at the highest position among the plurality of sub-openings 4041 .

[0095] In some embodiments, the liquid level control unit 50 may include a negative pressure source 51. The negative pressure source 51 can control the gas pressure in the storage chamber 403 by discharging the gas in the storage chamber 403 to the outside of the storage chamber 403. Furthermore, the negative pressure source 51 can discharge the gas in the storage chamber 403 to the collection chamber 402 or outside the storage box 40.

[0096] When the gas pressure in the storage chamber 403 decreases, the liquid in the collection chamber 402 is compressed by the atmospheric pressure and flows into the storage chamber 403 through the communication port 404 to balance the pressure difference between the inside and outside of the storage chamber 403 .

[0097] The negative pressure source 51 may use low-noise, low-power devices to reduce the impact on the user's life. In some scenarios, the negative pressure source 51 can work continuously to reduce the gas pressure in the storage chamber 403, so that the liquid level in the storage chamber 403 is higher than the liquid level in the collection chamber 402. In some scenarios, the negative pressure source 51 may work intermittently to reduce the gas pressure in the storage chamber 403, so that the liquid level in the storage chamber 403 is higher than the liquid level in the collection chamber 402. In some scenarios, the negative pressure source 51 may work intermittently to reduce the gas pressure in the storage chamber 403, so that the height difference between the liquid level in the storage chamber 403 and the liquid level in the collection chamber 402 is maintained within a preset height range. When the height difference is lower than the preset height range, the negative pressure source 51 can work.

[0098] The negative pressure source 51 can be directly installed at the connection port 4003, or it can be connected to the connection port 4003 through a pipeline. Of course, the connection can also be achieved in other ways. In some embodiments, the negative pressure source 51 may include a pump, a fan or other device capable of generating negative pressure. In some embodiments, the negative pressure source 51 can use a pump capable of suction, such as an air pump. In some scenarios, the negative pressure source 51 can control the liquid level in the storage chamber 403 to be higher than or flush with the liquid level in the collection chamber 402. In some scenarios, the negative pressure source 51 discharges the gas in the storage chamber 403 to the outside of the storage chamber 403, while achieving the suction of the liquid in the collection chamber 402 into the storage chamber 403.

[0099] In an optional embodiment, when the negative pressure source 51 is a pump, on the one hand, the noise can be effectively reduced, and on the other hand, since the pump itself has a closed effect, when the pump is not working, the air can be prevented from flowing back into the storage chamber 403 through the negative pressure source 51, so that the liquid level in the storage chamber 403 is higher than or flush with the liquid level in the collection chamber 402, that is, the negative pressure source 51 can work intermittently without worrying about water leakage.

[0100] In some embodiments, the liquid level control unit 50 may include a one-way valve 52. The one-way valve 52 is a device that allows air to flow only from its air inlet to its air outlet, but not from its air outlet back to its air inlet. The air inlet of the one-way valve 52 is connected to the storage chamber 403. The one-way valve 52 can control the gas pressure in the storage chamber 403 by discharging the gas in the storage chamber 403 from the air inlet to the air outlet to the outside of the storage chamber 403. Furthermore, the air outlet of the one-way valve 52 can be connected to the inside of the collection chamber 402 or the outside of the storage box 40, so that the gas in the storage chamber 403 can be discharged to the inside of the collection chamber 402 or the outside of the storage box 40. Optionally, when the cleaning device 10 is used to clean the floor to be cleaned, the cleaning device 10 is pushed and pulled back and forth, so that the liquid in the collection chamber 402 is surged back and forth and flows to the storage chamber 403 through the connecting port 404. At this time, since the volume of the gas in the storage chamber 403 becomes smaller (squeezed by the liquid), the gas pressure in the storage chamber 403 increases, so that the one-way valve 52 discharges the gas in the storage chamber 403 from the air inlet to the air outlet in a single direction to the outside of the storage chamber 403, so that the air pressure in the storage chamber 403 is reduced. In order to balance the air pressure, under the action of atmospheric pressure, the liquid can remain in the storage chamber 403 without flowing back to the collection chamber 40.

[0101] Optionally, during the process of pushing and pulling the cleaning device 10 back and forth, that is, when the cleaning device 10 moves forward and backward, the liquid in the collecting chamber 402 will flow to the storage chamber 403 through the connecting port 404, and due to the action of the one-way valve 52, the liquid in the storage chamber 403 will not flow to the collecting chamber 402, so that the liquid level in the storage chamber 403 will be higher than the collecting chamber 402. When the liquid volume of the entire containing box 40 is constant, the liquid level in the collecting chamber 402 can be lowered, thereby effectively improving the phenomenon of the liquid in the collecting chamber 402 gushing out from the drop port 1004.

[0102] The one-way valve 52 can be directly installed at the connection port 4003, or the air inlet and the connection port 4003 can be connected through a pipeline. Of course, the connection can also be achieved through other methods.

[0103] In some scenarios, the liquid in the collection chamber 402 surges as the cleaning device 100 moves forward and backward, and then enters the storage chamber 403 through the connecting port 404, causing the gas pressure in the storage chamber 403 to rise. In order to balance the pressure difference between the inside and outside of the storage chamber 403, the one-way valve 52 needs to discharge the gas in the storage chamber 403 in one direction to the outside of the storage chamber 403. The one-way valve 52 can discharge the gas in the storage chamber 403 to the inside of the collection chamber 402 or outside the storage box 40.

[0104] In some embodiments, the liquid level control unit 50 may include a negative pressure source 51 and a one-way valve 52. The one-way valve 52 is connected to the storage chamber 403, and the negative pressure source 51 may be connected to the one-way valve 52. The negative pressure source 51 may generate negative pressure, so that the gas in the storage chamber 403 is discharged to the outside of the storage chamber 403 through the one-way valve 52 in one direction under the negative pressure of the negative pressure source 51, so that the gas pressure in the storage chamber 403 decreases, and the liquid in the collection chamber 402 is compressed by the atmospheric pressure and flows to the storage chamber 403 through the connecting port 404 to balance the pressure difference between the inside and outside of the storage chamber 403.

[0105] In some embodiments, the liquid level control unit 50 may include a negative pressure source 51 and a one-way valve 52. The negative pressure source 51 may be directly installed at one connection port, or may be connected to one connection port through a pipeline, and of course, may be connected to the storage chamber 403 in other ways. The one-way valve 52 may be directly installed at another connection port, or may be connected to another connection port through a pipeline, and of course, may be connected to the storage chamber 403 in other ways. It can be understood that the respective functions of the negative pressure source 51 and the one-way valve 52 can refer to the description in the above embodiments, and will not be described in detail.

[0106] It is understandable that when the liquid level adjustment control unit 50 includes a negative pressure source 51 and a one-way valve 52, even if the negative pressure source 51 is disconnected from the one-way valve 52, the one-way valve 52 will maintain the liquid stored in the storage chamber 403 as much as possible. In addition, the negative pressure source 51 can also work intermittently without the need for the negative pressure source 51 to work all the time. In this case, the negative pressure source 51 can be a fan, etc., so that after the adjustment of the gas pressure in the storage chamber 403 is completed, the one-way valve 52 can be used to interrupt the work without continuous work. Further, the noise of the negative pressure source 51 during operation can be reduced, and the working noise of the negative pressure source 51 can be reduced.

[0107] Optionally, by setting a collecting chamber 402 and a storage chamber 403 in the containing box 40, and connecting the collecting chamber 402 and the storage chamber 403 through the connecting port 404, the storage chamber 403 is connected to the liquid level adjustment control unit 50. When garbage (including liquid) and the like enter the collecting chamber 402 through the box port 4001 and the liquid level is higher than the connecting port 404, the connecting port 404 of the storage chamber 403 will be sealed by the liquid, that is, the storage chamber 403 will become a better airtight system. At this time, the liquid level adjustment control unit 50 can regulate the gas pressure of its storage chamber 403 so that the liquid level of its storage chamber 403 can be higher than that of its collecting chamber 402. The connecting port 404 of the storage chamber 403 is airtight due to the liquid, so the liquid level adjustment control unit 50 can have a wide range of choices. On the one hand, it can work discontinuously (when the liquid level adjustment control unit 50 is not working, the gas pressure in the storage chamber 403 will remain constant due to the airtightness of the liquid in the connecting port 404, so that the liquid level will also remain constant), and on the other hand, its power can be greatly reduced (in an airtight system, only a small exhaust volume is required to achieve gas adjustment), thereby greatly reducing the cost of the liquid level adjustment control unit 50, such as a low-power pump or a low-power fan in combination with a one-way valve, or even an independent one-way valve, a structure that does not require power supply, thereby greatly saving the cost of the entire structure and effectively reducing noise.

[0108] See also Fig.12 , Fig.12 for Figure 6 The schematic diagram of the structure of the storage box 40 in other embodiments of the embodiment shown. Among them, the number of connection ports in the storage box 40 can be two, namely, the connection port 4003 and the connection port 4004. Among them, the negative pressure source 51 can be directly installed at the connection port 4003, or it can be connected to the negative pressure source 51 through a pipeline. The one-way valve 52 can be directly installed at the connection port 4004, or it can be connected to the one-way valve 52 through a pipeline.

[0109] See also Fig.10, the inner wall surface of the bottom wall 411 may include a guide surface 4111. The guide surface 4111 may guide the liquid to change the flow direction and / or flow velocity of the liquid. In some embodiments, at least part of the projection of the partition wall 42 in the normal direction of the support plane PL is located on the guide surface 4111, and then the guide surface 4111 may guide the liquid at the communication port 404 to change the flow direction and / or flow velocity of the liquid.

[0110] In some embodiments, on a cross section perpendicular to the support plane PL, the distance between the guide surface 4111 and the support plane PL gradually increases in the direction from the first side wall 412 to the second side wall 413, so that the guide surface 4111 is bent or inclined to the side away from the support plane PL, and can be extended into the storage chamber 403, or even into the storage chamber 403. Further, the guide surface 4111 guides the liquid upward into the storage chamber 403, so that the liquid in the collection chamber 402 can enter the storage chamber 403 to squeeze the gas in the storage chamber 403, and in the case where the liquid level adjustment control 50 includes a one-way valve 52, it is convenient for the air in the storage chamber 403 to be discharged from the storage chamber 403 in one direction. In some scenarios, the cross section can be perpendicular to the first axis, or have an angle of 0-20°. In some scenarios, the cross section can be parallel to the direction of travel, or have an angle of 0-20°.

[0111] In some scenarios, the liquid in the collection chamber 402 surges as the cleaning device 100 moves back and forth, and then enters the storage chamber 403 through the connecting port 404. The guide surface 4111 guides the liquid upward in the storage chamber 403, which makes it easier for the liquid in the collection chamber 402 to enter the storage chamber 403 and squeeze the gas in the storage chamber 403, causing the gas pressure in the storage chamber 403 to rise. In order to balance the pressure difference between the inside and outside of the storage chamber 403, the one-way valve 52 needs to discharge the gas in the storage chamber 403 in a single direction to the outside of the storage chamber 403.

[0112] In some embodiments, the curvature radius of the guide surface 4111 located between the partition wall 42 and the first side wall 412 is greater than the curvature radius of the guide surface 4111 located between the partition wall 42 and the second side wall 413, which facilitates the guide surface 4111 to guide the liquid upward into the storage cavity 403.

[0113] In some embodiments, on the cross section, the inner wall surface 4131 of the second side wall 413 is arranged in a curved shape protruding toward the side away from the first side wall 412, and the inner wall surface 4131 of the second side wall 413 is transitionally connected with the guide surface 4111, so that the inner wall surface 4131 of the second side wall 413 can guide the liquid to change the flow direction and / or flow rate of the liquid. The inner wall surface 4131 can guide the liquid upward in the storage cavity 403, and then facilitate the liquid in the collection cavity 402 to be guided into the storage cavity 403 through the guide surface 4111, and squeeze the gas in the storage cavity 403 again under the guidance of the inner wall surface 4131. In the case where the liquid level adjustment control 50 includes a one-way valve 52, it is convenient for the air in the storage cavity 403 to be discharged to the outside of the storage cavity 403 in one direction.

[0114] In some scenarios, the liquid in the collection chamber 402 surges as the cleaning device 100 moves back and forth, and then enters the storage chamber 403 through the connecting port 404. The guide surface 4111 guides the liquid upward in the storage chamber 403, and then guides the liquid upward in the storage chamber 403 again through the inner wall surface 4131, which makes it easy for the liquid in the collection chamber 402 to enter the storage chamber 403 and squeeze the gas in the storage chamber 403, causing the gas pressure in the storage chamber 403 to rise. In order to balance the pressure difference between the inside and outside of the storage chamber 403, the one-way valve 52 needs to discharge the gas in the storage chamber 403 in a single direction to the outside of the storage chamber 403.

[0115] In some embodiments, the curvature radius of the guide surface 4111 is greater than the curvature radius of the inner wall surface 4131 of the second side wall 413 , so that the guide surface 4111 cooperates with the inner wall surface 4131 of the second side wall 413 to guide the liquid upward into the storage cavity 403 .

[0116] In some embodiments, the inner wall surface of the first side wall 412 is arranged in a curved shape convex toward the side away from the second side wall 413. The liquid in the collection chamber 402 surges as the cleaning device 100 moves back and forth, and the inner wall surface of the first side wall 412 can provide buffering and shielding for the liquid, so that the liquid is not easy to surge out of the storage box 40 due to shaking, effectively improving the phenomenon of liquid spillage.

[0117] See also Fig.10 , the partition wall 42 may include a guide portion 422 disposed adjacent to the bottom wall 411. The guide portion 422 may guide the liquid, change the flow direction and / or flow rate of the liquid, facilitate the liquid to enter the storage chamber 403 from the collection chamber 402, and prevent the liquid from entering the collection chamber 402 from the storage chamber 403 in the reverse direction. In some embodiments, the guide portion 422 is inclined or curved toward the side where the second side wall 413 is located in the direction close to the bottom wall 411, and is spaced apart from the bottom wall 411 to form a communication port 404.

[0118] The guide portion 422 has an upper end 4221 and a lower end 4222 , wherein the distance between the upper end 4221 and the inner wall surface of the bottom wall 411 is greater than the distance between the lower end 4222 and the inner wall surface of the bottom wall 411 .

[0119] In some scenarios, when liquid enters the storage chamber 403 from the collection chamber 402, the guide portion 422 guides the liquid so that the pressure of the liquid between the upper end 4221 and the bottom wall 411 is less than the pressure of the liquid between the lower end 4222 and the bottom wall 411, and thus, the flow rate of the liquid between the lower end 4222 and the bottom wall 411 is greater than the flow rate of the liquid between the upper end 4221 and the bottom wall 411, thereby increasing the flow rate of the liquid at the connecting port 404, so that the liquid enters the storage chamber 403 at a higher flow rate, squeezing the liquid in the storage chamber 403.

[0120] In some scenarios, the liquid in the storage chamber 403 surges as the cleaning device 100 moves back and forth. In the process of the liquid entering the collection chamber 402 from the storage chamber 403, the guide portion 422 guides the liquid so that the liquid flows along the inner wall of the guide portion 422 in the storage chamber 403 toward the upper part of the storage chamber 403, thereby reducing the pressure on a small portion of the liquid located below the partition wall 42. Compared with the flow rate at the connecting port 404 when the liquid enters the storage chamber 403 from the collection chamber 402, the liquid flow rate is lower and flows into the collection chamber 402, thereby enabling the partition wall 42 to prevent the liquid from entering the collection chamber 402 from the storage chamber 403 in the opposite direction.

[0121] In some embodiments, on the cross section, the angle between the line between the upper end and the lower end of the guide portion 422 and the support plane PL can adjust the guiding effect of the guide portion 422 on the liquid.

[0122] In some embodiments, Fig. 9 As shown, the second plug-in portion 421 can be connected to the guide portion 422 , and the second plug-in portion 421 is inclined or bent toward the first side wall 412 in a direction close to the bottom wall 411 to improve the stability of the partition wall 42 .

[0123] In some embodiments, the inner wall surface of the storage box 40 has a lowest point. Specifically, the lowest point can be set on the bottom wall 411. In some embodiments, on this cross section, the ratio M / L of the distance M between the uppermost end 4042 of the edge of the communication port 404 and the lowest point in the direction perpendicular to the support plane PL and the distance L between the lowermost end 4002 of the edge of the box opening 4001 and the lowest point in the direction perpendicular to the support plane PL can control the capacity of the storage box 40, and even limit the working efficiency of the liquid level control unit 50 in controlling the liquid level.

[0124] In some embodiments, a distance M between the uppermost end 4042 of the communication opening 404 and the lowest point in a direction perpendicular to the support plane PL may be between 6 mm and 14 mm.

[0125] Optionally, by controlling the distance M between the uppermost end 4042 of the edge of the connecting port 404 and the lowest point in the direction perpendicular to the supporting plane PL to be between 6-14 mm, it is possible to prevent the connecting port 404 from being blocked by smaller garbage / liquid components due to being too small, and to prevent the connecting port 404 from being unable to be airtight / sealed by the liquid due to being too large.

[0126] In some embodiments, the distance L between the lowermost end 4002 of the edge of the box opening 4001 and the lowest point in the direction perpendicular to the supporting plane PL may be between 40 and 60 mm.

[0127] When the ratio M / L is large, the liquid in the storage chamber 403 is likely to surge as the cleaning device 100 moves back and forth, and the liquid level in the storage chamber 403 will be lower than the uppermost end 4042 of the edge of the connecting port 404, causing the liquid in the storage chamber 403 to flow back into the collecting chamber 402. It is therefore necessary to improve the efficiency of the liquid level control unit 50 in controlling the liquid level to prevent the liquid in the storage chamber 403 from flowing back into the collecting chamber 402.

[0128] When the ratio M / L is small, the liquid in the collection chamber 402 cannot flow quickly into the storage chamber 403, but is easy to flow out from the box mouth 4001. Therefore, it is necessary to improve the efficiency of the liquid level control unit 50 in controlling the liquid level to speed up the flow of the liquid in the collection chamber 402 into the storage chamber 403.

[0129] It can be understood that when the working efficiency of the liquid level control unit 50 in controlling the liquid level is certain, it is further necessary to control the ratio M / L.

[0130] The liquid in the collection chamber 402 surges as the cleaning device 100 moves forward and backward, and is easy to surge out from the box opening 4001. In order to further improve the phenomenon of surging from the storage box 40, please refer to Fig.13 , Fig.13 for Fig.10 In the schematic diagram of the structure of the box body 41 in some embodiments shown in the embodiment, the distance O between the lower end 4222 of the guide portion 422 and the first side wall 412 in the traveling direction is smaller than the distance P between the lower end 4222 and the second side wall 413, and the distance O is used to limit the space in the collection chamber 402 where liquid can flow, thereby improving the phenomenon of liquid flow, and thereby improving the phenomenon of liquid flowing out of the storage box 40. In some embodiments, the ratio between the distance O and the distance P is in the range of 0.2-0.8.

[0131] Optionally, the guide portion 422 may also be inclined toward the first side wall 412 , so that a distance O between a lower end 4222 of the guide portion 422 and the first side wall 412 in the traveling direction is smaller.
