Description

Cleaning device

[0001] The present application claims priority from the international patent application No. PCT / CN2024 / 100765, filed on June 21, 2024, and entitled "Cleaning device", the content of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of liquid working, and in particular, to a cleaning device.

BACKGROUND

[0003] The cleaning device is used to run in a water body, and can realize automatic cleaning of a pool and the like. An existing part of a cleaning device is provided with a water suction port. Water in the vicinity of the water suction port enters the cleaning device through the water suction port under the action of the suction force of the cleaning device, so as to realize underwater cleaning and filtration. Because the water suction port is arranged at a distance from the surface to be cleaned, water enters the water suction port from all directions, the water inflow speed into the water suction port is small, and thus the cleaning efficiency of the cleaning device is low.

[0004]

SUMMARY

[0005] The present disclosure provides a cleaning device to solve the technical problem that the liquid inflow speed is small and the cleaning efficiency of the cleaning device is low during the cleaning process of the cleaning device.

[0006] To solve the above technical problems, the present disclosure provides a cleaning device for operating in a water body, comprising: a cleaning device main body; at least one filtering mechanism, the filtering mechanism comprising at least one dust box and at least one dust box inlet portion in communication with the dust box; at least one liquid outlet portion provided on the top surface of the cleaning device main body; at least one liquid inlet portion, comprising a first liquid inlet portion, the first liquid inlet portion being transversely provided on the bottom of the cleaning device main body; at least one driving mechanism provided inside the cleaning device main body, for generating water flow suction force between the at least one liquid inlet portion and the at least one liquid outlet portion; a mode switching member provided on the cleaning device main body, for switching the cleaning device between a first motion state and a third motion state, the first motion state comprising performing an underwater cleaning task or traveling on a to-be-cleaned surface, and the third motion state comprising performing a water surface cleaning task or floating on the water surface; further comprising a first scraping strip and a second scraping strip provided immediately adjacent to both sides of the first liquid inlet portion, in the first motion state, at least one of the first scraping strip and the second scraping strip is in contact with the to-be-cleaned surface. In this way, by providing the first scraping strip and the second scraping strip at the rear and front of the first liquid inlet portion respectively, a substantially sealed liquid inlet flow channel can be formed. The liquid inlet flow channel is substantially perpendicular to the traveling direction of the cleaning device. During the traveling process of the cleaning device, especially during the cleaning process of the target bottom wall, under the action of the driving mechanism, external fluid flows into the first liquid inlet portion from the openings at the left and right ends of the liquid inlet flow channel, increasing the liquid inlet flow rate into the filtering mechanism through the first liquid inlet portion, thereby further effectively improving the cleaning efficiency.

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present disclosure.

[0045] Reference to“an embodiment” herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the disclosure. The appearances of the phrase“in an embodiment” in various places in the specification are not necessarily referring to the same embodiment, nor are they necessarily mutually exclusive of one another. It is expressly understood that any of the embodiments described herein can be incorporated into any other embodiment.

[0046] The cleaning device provided by the present application will be described in detail below in combination with embodiments.

[0047] Please refer to FIG. 1 to FIG. 3. FIG. 1 is a schematic diagram of a partial structure of a first embodiment of the cleaning device of the present disclosure. FIG. 2 is a schematic diagram of a first cross section of the first embodiment of the cleaning device of the present disclosure. FIG. 3 is a schematic diagram of a cross section of a filtering mechanism and a second device housing of the cleaning device of the present disclosure. The present disclosure provides a cleaning device 100. The cleaning device 100 can be but is not limited to a pool cleaning robot, a swimming pool cleaning robot, an underwater cleaning device, etc. The cleaning device 100 is used to run in a target area 400. The target area 400 can be an area filled with liquid where the cleaning device 100 moves. The target area 400 can be but is not limited to a swimming pool, a pool, an oil well, a sewer, etc. The cleaning device 100 is used to run in a water body. The target area 400 can include a target bottom wall 410 and a target side wall 420. In the present disclosure, the longitudinal direction of the cleaning device 100 can be defined as the extension direction along the connecting line of the centers of the front and rear of the cleaning device 100; and the transverse direction of the cleaning device 100 can be defined as the extension direction along the connecting line of the centers of the left and right sides of the cleaning device 100.

[0048] In some embodiments, the cleaning device 100 includes a cleaning device main body 110, at least one filtering mechanism 120, at least one driving mechanism 130, a liquid outlet 111, a liquid inlet 112, at least one liquid inlet switching member 113, and a mode switching member 140, etc. The filtering mechanism 120 is at least partially arranged in the front space of the cleaning device main body 110, and is used to filter stains and suspended matters, etc. of the water flow entering the cleaning device main body 110 from the target area 400. The filtering mechanism 120 includes a dust box 121 and a dust box inlet 1211 in communication with the dust box 121. The number of the driving mechanism 130 can be but is not limited to one, two, etc. The driving mechanism 130 is used to generate suction force. The driving mechanism 130 can be but is not limited to a main water pump 131, etc. The liquid outlet 111 is arranged in the cleaning device main body 110, and is used to discharge the fluid in the cleaning device 100 into the target area 400.

[0049] The liquid inlet part 112 includes, but is not limited to, a first liquid inlet part 1121 and a second liquid inlet part 1122. The first liquid inlet part 1121 is located at the bottom of the cleaning device main body 110. The first liquid inlet part 1121 can be arranged at the bottom of the cleaning device main body 110 or the bottom of the filtering mechanism 120, etc. A first fluid passage a is formed between the first liquid inlet part 1121 and the dust box inlet part 1211. The first liquid inlet part 1121 provides an entrance for external fluid to flow into the first fluid passage a, and then enters the dust box 121 through the dust box inlet part 1211. The second liquid inlet part 1122 is arranged on a surface of the cleaning device main body 110 different from the surface on which the first liquid inlet part 1121 is arranged.

[0050] In an embodiment, the second liquid inlet part 1122 can be arranged on the side of the cleaning device main body 110 or the side of the filtering mechanism 120, etc., and is arranged separately from the first liquid inlet part 1121. A second fluid passage b is formed between the second liquid inlet part 1122 and the dust box inlet part 1211. The second liquid inlet part 1122 provides an entrance for external fluid to flow into the second fluid passage b, and then enters the dust box 121 through the dust box inlet part 1211. That is, external fluid flows into the dust box 121 through the first liquid inlet part 1121 and the first fluid passage a, or the second liquid inlet part 1122 and the second fluid passage b, and the garbage in the external fluid is filtered. The first dust box inlet 12111 of the dust box inlet part 1211 corresponding to the first liquid inlet part 1121 and the second liquid inlet part 1122 is communicated.

[0051] In an embodiment, the dust box inlet part 1211 corresponding to the first liquid inlet part 1121 and the second liquid inlet part 1122 is a different dust box inlet, i.e., the dust box inlet part 1211 includes at least a second dust box inlet 12112 and a third dust box inlet 12113. The first liquid inlet part 1121 is communicated with the second dust box inlet 12112 through the first fluid passage a, and the second liquid inlet part 1122 is communicated with the third dust box inlet 12113 through the second fluid passage b.

[0052] At least one liquid inlet switching member 113 is arranged in the first fluid passage a and / or the second fluid passage b. The number of liquid inlet switching members 113 can be, but is not limited to, one and two, etc. The at least one liquid inlet switching member 113 is used to selectively open the first fluid passage a and the second fluid passage b. When the number of liquid inlet switching members 113 is one, the liquid inlet switching member 113 is used to switch the first fluid passage a and the second fluid passage b to be opened or closed. For example, when the liquid inlet switching member 113 opens the first fluid passage a, the liquid inlet switching member 113 closes the second fluid passage b; when the liquid inlet switching member 113 closes the first fluid passage a, the liquid inlet switching member 113 opens the second fluid passage b. When the number of liquid inlet switching members 113 is two, one liquid inlet switching member 113 opens or closes the first fluid passage a, and the other liquid inlet switching member 113 opens or closes the second fluid passage b. That is, the first fluid passage a and the second fluid passage b are independently controlled by the two liquid inlet switching members 113.

[0053] It can be understood that when the liquid inlet switching member 113 controls the opening and / or closing of the first fluid passage a and / or the second fluid passage b, the liquid inlet switching member 113 can also include simultaneously opening the first fluid passage a and the second fluid passage b. For example, when the number of liquid inlet switching members 113 is one, it can be controlled to be located at a position that partially opens the first fluid passage a and partially opens the second fluid passage b; when the number of liquid inlet switching members 113 is two, the first fluid passage a and the second fluid passage b can be simultaneously opened.

[0054] The mode switching member 140 is arranged in the cleaning device main body 110. The mode switching member 140 is used to adjust the pose of the cleaning device 100 to enable the cleaning device 100 to perform switching between the first motion state and the third motion state. For example, the mode switching member 140 adjusts the force received by the cleaning device 100 in the vertical direction, so that the cleaning device 100 can move in the vertical direction to enable the cleaning device 100 to switch between the first motion state and the third motion state. The vertical direction can be the vertical direction of the target area 400, for example, the vertical direction of the swimming pool, i.e. the direction of gravity. The horizontal direction can be the horizontal direction of the target area 400. For example, the horizontal direction of the swimming pool, i.e. the direction perpendicular to the direction of gravity.

[0055] Please refer to FIG. 4 to FIG. 7, FIG. 4 is a schematic diagram of the first embodiment of the cleaning device of the present disclosure moving on a target bottom wall of a target area; FIG. 5 is a schematic diagram of the first embodiment of the cleaning device of the present disclosure moving on a target side wall of a target area; FIG. 6 is a schematic diagram of the first embodiment of the cleaning device of the present disclosure floating on the water surface; FIG. 7 is a schematic diagram of the first embodiment of the cleaning device of the present disclosure switching between the target bottom wall and the target side wall of the target area. In combination with FIG. 1 to FIG. 3, the cleaning device 100 is defined as the first motion state when it walks on the target bottom wall 410 or the overall direction of the cleaning device 100 is at an angle less than 90° with the target bottom wall 410 and away from the water surface 300, which can be understood as the cleaning device 100 performing pool bottom cleaning work, performing actions in the water, etc., as shown in FIG. 4. The cleaning device 100 is defined as the second motion state when it walks on the target side wall 420 or the overall direction of the cleaning device 100 is substantially parallel to the target side wall 420, as shown in FIG. 5. The cleaning device 100 is defined as the third motion state when it travels on the water surface 300, or at least part of the cleaning device 100 is exposed to the water surface 300, or the overall cleaning device 100 is located below the water surface 300 and close to the water surface 300, which can be understood as the distance between the cleaning device 100 and the water surface 300 is less than a threshold value, and the cleaning device 100 can perform water surface cleaning tasks, etc., as shown in FIG. 6. The plane of the cleaning device 100 in contact with the surface to be cleaned can be defined as the overall direction of the cleaning device 100. The cleaning device 100 switches between the first motion state and the third motion state, i.e. the cleaning device 100 switches between the position under the water and the water surface 300, which can or can not include the process of the second motion state, for example: when the cleaning device 100 is in the first motion state, it first converts to the second motion state until the cleaning device 100 is at least partially exposed to the water surface, and then switches to the third motion state, or directly switches from the first motion state to the third motion state; when the cleaning device 100 is in the third motion state, it first converts to the second motion state until it sinks to the target bottom wall 410, and then adjusts to the first motion state, or directly starts to sink to the first motion state from the third motion state. That is, the position of the cleaning device 100 under the water and the water surface 300 can be adjusted according to different water environments and needs, so that the cleaning device 100 can more flexibly perform corresponding operations at different positions in the water.

[0056] Referring to FIG. 8, FIG. 8 is a structural schematic diagram of the first water flow path in the first embodiment of the cleaning device of the present disclosure. In combination with FIG. 1, FIG. 2, FIG. 3 and FIG. 4, the first motion state includes performing underwater cleaning work. When the cleaning device 100 needs to perform underwater cleaning work, the mode switching member 140 adjusts the posture of the cleaning device 100 to the first motion state, the first liquid inlet portion 1121 faces the surface to be cleaned, the liquid inlet switching member 113 opens the first fluid path a, at this time the first fluid path a is in a flow state. The driving mechanism 130 generates suction force, and the first water flow path c is formed by the first liquid inlet portion 1121, the dust box inlet portion 1211, the dust box 121 and the liquid outlet portion 111, so that the water flow carrying garbage is sucked into the filtering mechanism 120 through the first liquid inlet portion 1121, and flows out from the liquid outlet portion 111 after being filtered by the filtering mechanism 120, thereby completing the cleaning process of the target bottom wall 410.

[0057] Referring to FIG. 9, FIG. 9 is a structural schematic diagram of the second water flow path in the first embodiment of the cleaning device of the present disclosure. In combination with FIG. 1, FIG. 2, FIG. 3 and FIG. 6, the third motion state includes performing surface cleaning work. When the cleaning device 100 needs to perform surface cleaning work, the mode switching member 140 adjusts the posture of the cleaning device 100 to the third motion state, the second liquid inlet portion 1122 is at least partially located above the water surface 300, and the liquid inlet switching member 113 opens the second fluid path b, at this time the second fluid path b is in a flow state. When the cleaning device 100 performs work on the water surface 300, the second water flow path d is formed by the second liquid inlet portion 1122, the dust box inlet portion 1211, the dust box 121 and the liquid outlet portion 111, so that the water flow carrying the garbage floating on the water surface is sucked into the filtering mechanism 120 through the second liquid inlet portion 1122, thereby realizing the cleaning process of the water surface. Among them, the first water flow path c and the second water flow path d at least partially overlap.

[0058] Therefore, through the cooperation of the above-mentioned cleaning device main body 110, at least one filtering mechanism 120, at least one driving mechanism 130, liquid outlet portion 111, liquid inlet portion 112, at least one liquid inlet switching member 113 and mode switching member 140, not only can the cleaning device 100 switch between the first motion state and the third motion state, thereby changing the posture of the cleaning device 100 underwater cleaning work and surface cleaning work; but also forms at least two water flow paths to meet the cleaning needs of at least two working conditions of underwater cleaning and surface cleaning. That is, the cleaning device 100 can perform underwater cleaning work and surface cleaning work, which expands the use scene of the cleaning device 100, reduces the use cost, and improves the user experience.

[0059] The at least one liquid inlet switching member 113 can be arranged at any position of the first fluid passage a and / or the second fluid passage b. For example, the liquid inlet switching member 113 can be arranged at one end of the first fluid passage a close to the first liquid inlet portion 1121, or in the middle of the first fluid passage a, or at one end of the first fluid passage a close to the dust box inlet portion 1211, etc. Alternatively, the liquid inlet switching member 113 can be arranged at one end of the second fluid passage b close to the second liquid inlet portion 1122, or in the middle of the second fluid passage b, or at one end of the second fluid passage b close to the dust box inlet portion 1211, etc. The arrangement of the liquid inlet switching member 113 at the first liquid inlet portion 1121 and / or the second liquid inlet portion 1122 will be described in detail below.

[0060] Referring to FIGS. 10 and 11, FIG. 10 is a schematic structural view of the filtering mechanism and the second device housing in the first embodiment of the cleaning device of the present disclosure, and FIG. 11 is a schematic structural view of the filtering mechanism in the first embodiment of the cleaning device of the present disclosure. In one embodiment, when the cleaning device 100 comprises one liquid inlet switching member 113, the liquid inlet switching member 113 is arranged at the first liquid inlet portion 1121 or the second liquid inlet portion 1122, and is used to switch the first liquid inlet portion 1121 and the second liquid inlet portion 1122 to be opened or closed. When the cleaning device 100 performs underwater cleaning work, the liquid inlet switching member 113 opens the first liquid inlet portion 1121, and the liquid inlet switching member 113 closes the second liquid inlet portion 1122. At this time, the first fluid passage a is in an open state, and the second fluid passage b is in a closed state. When the cleaning device 100 performs surface cleaning work, the liquid inlet switching member 113 opens the second liquid inlet portion 1122, and the liquid inlet switching member 113 closes the first liquid inlet portion 1121. At this time, the second fluid passage b is in an open state, and the first fluid passage a is in a closed state.

[0061] In another embodiment, when the cleaning device 100 comprises two liquid inlet switching members 113, one liquid inlet switching member 113 can be arranged at the first liquid inlet portion 1121 in an openable and closable manner, i.e., the liquid inlet switching member 113 independently opens or closes the first liquid inlet portion 1121. Another liquid inlet switching member 113 can be arranged at the second liquid inlet portion 1122 in an openable and closable manner, i.e., the liquid inlet switching member 113 independently opens or closes the second liquid inlet portion 1122. When the cleaning device 100 performs underwater cleaning work, one liquid inlet switching member 113 opens the first liquid inlet portion 1121, and the first fluid passage a is opened. Another liquid inlet switching member 113 closes the second liquid inlet portion 1122, and the second fluid passage b is closed. When the cleaning device 100 performs surface cleaning work, one liquid inlet switching member 113 closes the first liquid inlet portion 1121, and the first fluid passage a is closed. Another liquid inlet switching member 113 opens the second liquid inlet portion 1122, and the second fluid passage b is opened.

[0062] By setting the liquid inlet switching member 113 at the first liquid inlet part 1121 and / or the second liquid inlet part 1122, not only the space occupation of the dust box 121 is reduced, but also the distance between the liquid inlet switching member 113 and the external fluid is shortened, so as to facilitate the water flow carrying garbage to enter the dust box 121. When the number of the liquid inlet switching member 113 is one, it is convenient to switch back and forth between the first liquid inlet part 1121 and the second liquid inlet part 1122, and the structure is simplified and the cost is reduced.

[0063] In some embodiments, the liquid inlet switching member 113 includes at least one baffle 1131 and a baffle driving member 1132. The baffle driving member 1132 is connected with the at least one baffle 1131. The baffle driving member 1132 drives the baffle 1131 to switch between at least a first state and a second state. In the first state, the baffle 1131 opens the first fluid passage a. In the second state, the baffle 1131 opens the second fluid passage b. The number of baffles 1131 can be but not limited to one and two, etc. The baffle driving member 1132 provides driving force to move the at least one baffle 1131 for opening or closing the first fluid passage a or the second fluid passage b. The baffle driving member 1132 can be but not limited to a baffle driving motor (not shown in the figure) and other driving members, etc. The baffle 1131 is used for opening or closing the first fluid passage a and the second fluid passage b. Through the cooperation of the above-mentioned baffle 1131 and the baffle driving member 1132, the structure is simple and easy to install and disassemble, etc. The above-mentioned baffle 1131 can be arranged at any position of the first fluid passage a and / or the second fluid passage b, which is not limited here.

[0064] The cleaning device 100 includes a liquid inlet switching member 113, which includes a baffle 1131 and a baffle driving member 1132. The baffle 1131 is used to switch the first liquid inlet part 1121 and the second liquid inlet part 1122 to open or close. The baffle 1131 has at least a first state and a second state. When the baffle 1131 is in the first state, the baffle 1131 opens the first liquid inlet part 1121, and at the same time the baffle 1131 closes the second liquid inlet part 1122. When the baffle 1131 is in the second state, the baffle 1131 closes the first liquid inlet part 1121, and at the same time the baffle 1131 opens the second liquid inlet part 1122.

[0065] The cleaning device 100 includes a liquid inlet switching member 113, which can include two baffles 1131 and a baffle driving member 1132.

[0066] The cleaning device 100 comprises two liquid inlet switching members 113, each of which comprises a baffle 1131 and a baffle driving member 1132. That is, one baffle 1131 opens the first liquid inlet portion 1121, and the other baffle 1131 closes the second liquid inlet portion 1122; or one baffle 1131 closes the first liquid inlet portion 1121, and the other baffle 1131 opens the second liquid inlet portion 1122.

[0067] In some embodiments, the dust box inlet portion 1211 comprises a first dust box inlet 12111. The first liquid inlet portion 1121 and the second liquid inlet portion 1122 are both in communication with the first dust box inlet 12111. The cleaning device 100 further comprises an auxiliary cavity 125. The auxiliary cavity 125 is located upstream of the first dust box inlet 12111; at the same time, the auxiliary cavity 125 is located downstream of the first liquid inlet portion 1121 and the second liquid inlet portion 1122. When the auxiliary cavity 125 is located upstream of the first dust box inlet 12111, the auxiliary cavity 125 can be at least partially located in the lower part of the dust box 121, or can be located on the side of the dust box 121. For example, the auxiliary cavity 125 can be partially located in the lower part of the dust box 121; or the auxiliary cavity 125 can be entirely located in the lower part of the dust box 121. The auxiliary cavity 125 is in communication with the first dust box inlet 12111, so that the auxiliary cavity 125 and the dust box 121 are in communication. The first liquid inlet portion 1121 is arranged at the bottom of the auxiliary cavity 125, and external fluid flows into the auxiliary cavity 125 through the first liquid inlet portion 1121 at the bottom of the auxiliary cavity 125, and then flows into the dust box 121 through the first dust box inlet 12111. The second liquid inlet portion 1122 is arranged on the side of the auxiliary cavity 125, and external fluid flows into the auxiliary cavity 125 through the second liquid inlet portion 1122 of the auxiliary cavity 125, and then flows into the dust box 121 through the first dust box inlet 12111. At least one liquid inlet switching member 113 is arranged in the auxiliary cavity 125.

[0068] The liquid inlet switching member 113 is located in the auxiliary cavity 125. The cleaning device 100 can provide installation positions for the at least one liquid inlet switching member 113 through the auxiliary cavity 125, thereby facilitating the installation, disassembly, etc. of the liquid inlet switching member 113. When the number of liquid inlet switching members 113 is one, the liquid inlet switching member 113 moves in the auxiliary cavity 125 to switch the first liquid inlet part 1121 and the second liquid inlet part 1122 to be opened or closed. When the number of liquid inlet switching members 113 is two, each liquid inlet switching member 113 independently opens or closes the corresponding first liquid inlet part 1121 and the second liquid inlet part 1122, etc. The auxiliary cavity 125 is used to form the first fluid passage a and the second fluid passage b. Alternatively, the first liquid inlet part 1121 and the first dust box inlet 12111 are connected through a pipe, and the pipe forms the first fluid passage a; the second liquid inlet part 1122 and the first dust box inlet 12111 are connected through another pipe, and the other pipe forms the second fluid passage b, wherein the two pipes are arranged in the auxiliary cavity 125.

[0069] In addition, the auxiliary cavity 125 and the dust box 121 can be an integrated structure or a split structure. When the auxiliary cavity 125 and the dust box 121 are an integrated structure, the auxiliary cavity 125 is taken out or put in together with the dust box 121. When the auxiliary cavity 125 and the dust box 121 are a split structure, the dust box 121 and the auxiliary cavity 125 can be taken out or put in separately; or the auxiliary cavity 125 is fixedly arranged in the dust box compartment 1152, and the dust box 121 can be taken out or put in the dust box compartment 1152 alone.

[0070] When the cleaning device 100 performs underwater cleaning work, the first liquid inlet part 1121 is opened, and the second liquid inlet part 1122 is closed, wherein the first liquid inlet part 1121, the auxiliary cavity 125, the first dust box inlet 12111, the dust box 121, the dust box outlet part, and the liquid outlet part 111 form the first water flow passage c. When the cleaning device 100 performs surface cleaning work, the first liquid inlet part 1121 is closed, and the second liquid inlet part 1122 is opened, wherein the second liquid inlet part 1122, the auxiliary cavity 125, the first dust box inlet 12111, the dust box 121, and / or the dust box outlet part and / or the liquid outlet part 111 form the second water flow passage d.

In some embodiments, the dust box inlet portion 1211 includes a second dust box inlet 12112 and a third dust box inlet 12113. The first liquid inlet portion 1121 is in openable and closable communication with the second dust box inlet 12112 through a liquid inlet switching member 113, which can open or close the communication between the first liquid inlet portion 1121 and the second dust box inlet 12112, thereby opening or closing the first fluid passage a. The second liquid inlet portion 1122 is in openable and closable communication with the third dust box inlet 12113 through the liquid inlet switching member 113, which can open or close the communication between the second liquid inlet portion 1122 and the third dust box inlet 12113, thereby opening or closing the second fluid passage b.

[0072] By providing the second dust box inlet 12112 and the third dust box inlet 12113 on the dust box 121, the influence between the first fluid passage a and the second fluid passage b is reduced, thereby reducing the influence between the underwater cleaning work and the surface cleaning work, and improving the filtering efficiency of the cleaning device 100, etc.

By canceling the auxiliary cavity 125, the cleaning device 100 can increase the size of the dust box 121, thereby increasing the cleaning efficiency of the cleaning device 100. The number of the above-mentioned liquid inlet switching member 113 is not limited.

[0075] In another embodiment, the first liquid inlet 1121 is spaced apart from the second dust box inlet 12112. The second liquid inlet 1122 is spaced apart from the third dust box inlet 12113. The cleaning device 100 comprises an auxiliary cavity 125. The auxiliary cavity 125 is provided with the first liquid inlet 1121 and the second liquid inlet 1122. The auxiliary cavity 125 is in communication with the second dust box inlet 12112 and the third dust box inlet 12113, respectively. The auxiliary cavity 125 is formed with a first fluid passage a and a second fluid passage b, wherein the first fluid passage a and the second fluid passage b can at least partially overlap.

[0076] When the cleaning device 100 performs underwater cleaning work, the first liquid inlet 1121 is opened, and the second liquid inlet 1122 is closed. The first liquid inlet 1121, the auxiliary cavity 125, the second dust box inlet 12112, the dust box 121, the dust box outlet portion, and the liquid outlet portion 111 form a first water flow passage c. When the cleaning device 100 performs surface cleaning work, the first liquid inlet 1121 is closed, and the second liquid inlet 1122 is opened. The second liquid inlet 1122, the auxiliary cavity 125, the third dust box inlet 12113, the dust box 121, and / or the dust box outlet portion and / or the liquid outlet portion 111 form a second water flow passage d.

[0077] In other embodiments, the first liquid inlet 1121 is spaced apart from the second dust box inlet 12112. The second liquid inlet 1122 is spaced apart from the third dust box inlet 12113. The cleaning device 100 comprises two auxiliary cavities 125. One auxiliary cavity 125 is provided with the first liquid inlet 1121 at the bottom, and the auxiliary cavity 125 is in communication with the second dust box inlet 12112. The other auxiliary cavity 125 is provided with the second liquid inlet 1122 at the side, and the auxiliary cavity 125 is in communication with the third dust box inlet 12113. The two auxiliary cavities 125 are independently provided and not in communication with each other. At this time, the number of liquid inlet switching members 113 is two.

[0078] When the cleaning device 100 performs underwater cleaning work, the first liquid inlet 1121 is opened, and the second liquid inlet 1122 is closed. The first liquid inlet 1121, the auxiliary cavity 125, the second dust box inlet 12112, the dust box 121, the dust box outlet portion, and the liquid outlet portion 111 form a first water flow passage c. When the cleaning device 100 performs surface cleaning work, the first liquid inlet 1121 is closed, and the second liquid inlet 1122 is opened. The second liquid inlet 1122, the auxiliary cavity 125, the third dust box inlet 12113, the dust box 121, and / or the dust box outlet portion and / or the liquid outlet portion 111 form a second water flow passage d.

[0079] In the different embodiments described above, the first water flow passage c and the second water flow passage d can be formed in various forms. The first water flow passage c and the second water flow passage d can be related to the number of dust box inlets in the dust box inlet portion 1211 and the number of auxiliary cavities 125, and the like, which are not limited herein.

[0080] In some embodiments, the filtering mechanism 120 further comprises a bin door (not shown in the figures). The bin door is arranged on the dust box 121, for example, can be arranged on the outside or inside of the dust box 121; and the bin door can be arranged in an openable and closable manner on the dust box inlet portion 1211. By arranging the bin door on the dust box inlet portion 1211 of the dust box 121, the risk of leakage of garbage and the like in the dust box 121 can be reduced. The bin door can be pivotally connected to the dust box 121 and can be opened or closed relative to the dust box inlet portion 1211. For example, the pivoting manner can be, but is not limited to, rotation, and the like.

[0081] In a specific embodiment, the bin door comprises a first bin door 122 and a second bin door 123. The first bin door 122 and the second bin door 123 are arranged on the dust box 121. The second liquid inlet portion 1122 is provided with a liquid inlet switching member 113, wherein the action of the liquid inlet switching member 113 can open or close the second bin door 123. For example, the second bin door 123 is closed in the first position, and the second bin door 123 is opened in the second position, and when the liquid inlet switching member 113 is in the second position, the second bin door 123 is opened, and at the same time, the first bin door 122 is pressed to prevent the opening of the first bin door 122. The first bin door 122 is arranged in an openable and closable manner on the second dust box inlet 12112, and the second bin door 123 is arranged in an openable and closable manner on the third dust box inlet 12113.

[0082] When the cleaning device 100 performs the pool bottom cleaning task in the first motion state or performs the pool wall or water line cleaning task in the second motion state, the first fluid passage a is opened, and under the suction action of the driving mechanism 130, the first bin door 122 forms a negative pressure close to the inside of the dust box 121, so that the first bin door 122 rotates towards the inside of the dust box 121 and opens the second dust box inlet 12112. At this time, the liquid inlet switching member 113 is in the position shown in FIG. 14, and the second bin door 123 is in a normally closed state. When the cleaning device 100 is not working, the first fluid passage a is closed, and the first bin door 122 automatically returns to the original state, the first bin door 122 closes the second dust box inlet 12112, and reduces the risk of leakage of garbage and the like in the dust box 121 through the second dust box inlet 12112.

[0083] When the cleaning device 100 is in the third motion state and performs the water surface cleaning task, the second fluid passage b is open, the second liquid inlet part 1122 is at least partially above the water surface 300, the liquid inlet switching member 113 is rotated to the inside space of the dust box 121 under the action of the driving mechanism, thereby driving the second bin door 123 to also rotate to the inside space of the dust box 121, that is, the third dust box inlet 12113 is open. At this time, even under the suction action of the driving mechanism 130, the first bin door 122 still remains in the closed state.

[0084] When the cleaning device 100 is not working, the second fluid passage b is closed, the second bin door 123 automatically returns to the original state, the second bin door 123 closes the third dust box inlet 12113, reducing the risk of leakage of garbage and the like in the dust box 121 through the third dust box inlet 12113. Of course, the form of opening the second bin door 123 can also not be limited to the form of the liquid inlet switching member 113 described above, but also can be movement under the action of gravity or other driving forms. The first bin door 122 and the second bin door 123 can be flexible materials. The liquid inlet switching member 113 can be a baffle 1131.

[0085] Please refer back to FIG. 2 and FIG. 3, in another specific embodiment, the bin door includes a third bin door 124. The third bin door 124 is arranged in the dust box 121; at the same time, the third bin door 124 is arranged in the first dust box inlet 12111 in a closable manner. When the cleaning device 100 performs underwater cleaning work or water surface cleaning work, the first fluid passage a or the second fluid passage b is open, the third bin door 124 is opened and the first dust box inlet 12111 is opened under the action of the suction force of the driving mechanism 130. When the cleaning device 100 is not working, the third bin door 124 automatically returns to the original state and closes the first dust box inlet 12111, reducing the risk of leakage of garbage and the like in the dust box 121 through the first dust box inlet 12111.

[0086] In other specific embodiments, the first bin door 122 and the second bin door 123 or the third bin door 124 can also be arranged in the auxiliary cavity 125. That is, the arrangement positions of the above-mentioned first bin door 122, the second bin door 123 and the third bin door 124 can be determined according to actual needs, which are not limited here.

[0087] Please continue to refer to FIG. 2, FIG. 3, FIG. 8, FIG. 9 and FIG. 12, in some embodiments, the cleaning device 100 further comprises a cleaning mechanism 150. The cleaning mechanism 150 comprises at least one cleaning element 151. The number of cleaning elements 151 can be but is not limited to one, two, three or more. The cleaning element 151 can be but is not limited to a roller brush or the like. The cleaning element 151 can be used to clean the target bottom wall 410 and the target side wall 420 of the pool. The cleaning device 100 further comprises a cleaning bin 1141. The cleaning bin 1141 is arranged at the lower position of the front and / or rear of the cleaning device main body 110. The cleaning bin 1141 is used to accommodate at least one cleaning element 151. In addition to being arranged in the cleaning bin 1141, the cleaning element 151 can also be arranged at other positions of the cleaning device main body 110. As in the present embodiment, at least one cleaning element 151 can be arranged at the front and rear ends of the bottom of the cleaning device 100, respectively. When the cleaning device 100 moves on the target bottom wall 410 of the pool, the cleaning element 151 can clean the target bottom wall 410 of the pool, such as sweeping impurities or algae or the like. When the cleaning device 100 moves on the target side wall 420 of the pool, the cleaning element 151 can also clean the target side wall 420 of the pool.

[0088] In the length direction of the second liquid inlet portion 1122, at least part of the second liquid inlet portion 1122 is arranged laterally within the area of the cleaning bin 1141, which can increase the contact area between the second liquid inlet portion 1122 and the water surface 300 and improve the cleaning efficiency. In the width direction of the second liquid inlet portion 1122, at least part of the second liquid inlet portion 1122 is located within the area of the cleaning bin 1141, or at least part of the second liquid inlet portion 1122 is located at the bottom of the cleaning device main body 110. The second liquid inlet portion 1122 is arranged at the front position of the bottom of the cleaning device main body 110. The cleaning element 151 and the second liquid inlet portion 1122 are arranged closely, so that the cleaning element 151 can roll the garbage and the like into the vicinity of the second liquid inlet portion 1122; at the same time, the distance between the first liquid inlet portion 1121 and the second liquid inlet portion 1122 is shortened, thereby the flow distance of the water flow between the first liquid inlet portion 1121, the second liquid inlet portion 1122 and the filtering mechanism 120 is shortened, and the filtering efficiency is improved. That is, the cleaning device 100 can share the filtering mechanism 120 when performing underwater cleaning work and water surface cleaning work.

[0089] When the cleaning device 100 performs water surface cleaning work, the cleaning element 151 is at least partially located below the water surface 300, and the cleaning element 151 acts as a disturbing element and rotates counterclockwise, which can roll the water surface garbage and the like into the filtering mechanism 120 through the second liquid inlet portion 1122. By jointly defining that the cleaning element 151 is at least partially located below the water surface 300 and the second liquid inlet portion 1122 is at least partially located above the water surface 300, the garbage cleaning effect is best, thereby improving the cleaning effect of the cleaning device 100.

[0090] In some embodiments, the cleaning device body 110 comprises a first device housing 114. The first device housing 114 is provided with a cleaning bin 1141 at the front end. The cleaning element 151 is rotatably arranged in the cleaning bin 1141. The second liquid inlet portion 1122 is directly or indirectly communicated with the dust box inlet portion 1211 on the dust box 121. When the cleaning device 100 performs the water surface cleaning task, under the action of the cleaning element 151, the garbage and the like successively pass through the cleaning bin 1141, the second liquid inlet portion 1122, the dust box inlet portion 1211 and enter the dust box 121. The above-mentioned cleaning element 151 is spaced apart from the inner side wall of the cleaning bin 1141, which facilitates the water flow and the like to enter the cleaning bin 1141. At the same time, the cleaning element 151 is spaced apart from the second liquid inlet portion 1122, which facilitates the water flow to enter the dust box 121 through the second liquid inlet portion 1122. Through the above-mentioned arrangement, it is more convenient for the garbage and the like to enter the dust box 121. Of course, the cleaning element 151 can also be in contact with or at least partially interfere with the cleaning bin 1141. At this time, the driving mechanism 130 can form a negative pressure area with greater pressure in the cleaning bin 1141 area, which is beneficial to the water surface garbage near the cleaning bin 1141 to be sucked into the dust box 121.

[0091] In some embodiments, the cleaning device body 110 further comprises a second device housing 115. The second device housing 115 is provided with a liquid inlet channel 1151 near one side of the second liquid inlet portion 1122. The liquid inlet channel 1151 is a channel for garbage and water flow and the like to enter the dust box inlet portion 1211. The liquid inlet channel 1151 is hollow inside. The liquid inlet channel 1151 is arranged to extend along the transverse direction of the cleaning device 100. Among them, the size of the first port 11511 of the liquid inlet channel 1151 away from the dust box inlet portion 1211 is greater than the size of the second port 11512 of the liquid inlet channel 1151 close to the dust box inlet portion 1211. The liquid inlet channel 1151 can include but is not limited to a hollow truncated cone, a trapezoidal body and the like structure, and the channel between the first port 11511 and the second port 11512 is smoothly transitioned.

[0092] Specifically, the port size of the first port 11511 and the port size of the second port 11512 can be proportionally arranged. By arranging the liquid inlet channel 1151, the garbage on the wider water surface 300 can be accumulated together and enter the dust box inlet portion 1211, avoiding the reduction of the water surface cleaning efficiency of the cleaning device 100 due to the dust box inlet portion 1211 being too small.

[0093] Further, the second device housing 115 forms a dust box bin 1152. The dust box bin 1152 is used to accommodate the dust box 121. The liquid inlet channel 1151 is in communication with the cleaning bin 1141 and the dust box bin 1152, respectively. Further, the first port 11511 of the liquid inlet channel 1151 is at least partially or entirely disposed on the bin wall of the cleaning bin 1141, and the second port 11512 is at least partially or entirely disposed on the bin wall of the dust box bin 1152. During installation of the dust box 121 in the dust box bin 1152, the dust box inlet portion 1211 is in sealing abutment and communication with the second port 11512 of the liquid inlet channel 1151. The outer periphery of the dust box inlet portion 1211 and the second port 11512 can be provided with a sealing structure. By the above sealing abutment method, the sealing performance is improved, and the liquid leakage phenomenon is reduced.

[0094] In addition to being disposed at the front lower portion of the cleaning device main body 110, the second liquid inlet portion 1122 can also be disposed at the lower rear portion of the cleaning device main body 110. It should be noted that the positions of the first liquid inlet portion 1121 and the second liquid inlet portion 1122 are related to the position of the filtering mechanism 120. In order to minimize the length of the water flow path and improve work efficiency, when the filtering mechanism 120 is disposed at the front portion of the cleaning device 100, the first liquid inlet portion 1121 and the second liquid inlet portion 1122 are disposed at the front portion of the cleaning device 100. When the filtering mechanism 120 is disposed at the rear portion of the cleaning device 100, the first liquid inlet portion 1121 and the second liquid inlet portion 1122 are disposed at the rear portion of the cleaning device 100.

[0095] Referring to FIG. 15 to FIG. 17, FIG. 15 is a structural schematic diagram of a third embodiment of the cleaning device of the present disclosure; FIG. 16 is a structural schematic diagram of A shown in FIG. 15; FIG. 17 is a structural schematic diagram of the first scraping strip and the second scraping strip in the third embodiment of the cleaning device of the present disclosure. In combination with FIG. 2 and FIG. 12, in some embodiments, the cleaning device 100 comprises a first scraping strip 116 and a second scraping strip 117. The first scraping strip 116 and the second scraping strip 117 are arranged close to both sides of the first liquid inlet part 1121. Among them, the first scraping strip 116 and the second scraping strip 117 are located at the bottom of the cleaning device main body 110. The first scraping strip 116 is located at the rear of the first liquid inlet part 1121. The second scraping strip 117 is located at the front of the first liquid inlet part 1121. When the cleaning device 100 is in the first motion state, the first scraping strip 116 and the second scraping strip 117 at least one of them forms a contact interference with the surface to be cleaned. The first scraping strip 116 and the second scraping strip 117 close to the two opposite edges of the first liquid inlet part 1121 form a liquid inlet flow channel 118 with both ends open. The first liquid inlet part 1121 is located in the liquid inlet flow channel 118. Among them, the first liquid inlet part 1121 can be located at the left end, the right end or the middle of the liquid inlet flow channel 118, etc.

[0096] By arranging the first scraping strip 116 and the second scraping strip 117 at the rear and front of the first liquid inlet part 1121 respectively, a roughly sealed liquid inlet flow channel 118 can be formed. As shown in FIG. 15 and FIG. 16, the liquid inlet flow channel 118 is roughly perpendicular to the direction of travel of the cleaning device 100. During the travel of the cleaning device 100, especially during the cleaning process of the target bottom wall 410, the external fluid flows into the first liquid inlet part 1121 from the openings at both ends of the liquid inlet flow channel 118 under the action of the driving mechanism 130.

[0097] In some embodiments, at least one of the first scraping strip 116 and the second scraping strip 117 is arranged to extend horizontally along the bottom of the cleaning device main body 110. That is, the first scraping strip 116, or the second scraping strip 117, or the first scraping strip 116 and the second scraping strip 117 are arranged to extend horizontally along the bottom of the cleaning device main body 110. Among them, one end of the first scraping strip 116 and one end of the second scraping strip 117 are close to one side of the cleaning device main body 110, and the other end of the first scraping strip 116 and the other end of the second scraping strip 117 are close to the other side of the cleaning device main body 110. By limiting the shape and position of the first scraping strip 116 and the second scraping strip 117, the length of the liquid inlet flow channel 118 is increased, and the cleaning efficiency is further improved, etc.

[0098] In one embodiment, the first scraping strip 116 is arranged to extend horizontally along the bottom of the cleaning device body 110, and the second scraping strip 117 can be of any shape as long as one end of the second scraping strip 117 is close to one side edge of the cleaning device body 110 and the other end of the second scraping strip 117 is close to the other side edge of the cleaning device body 110. For example, the second scraping strip 117 can be of a shape of a "flared" end, an arc, an inclined shape, a curved shape, or the like. When the second scraping strip 117 is of a "flared" end shape, the "flared" end can be directed towards the forward or backward direction of the cleaning device 100. When the second scraping strip 117 is of an arc shape, the arc top can be directed towards the forward or backward direction of the cleaning device 100.

[0099] In another embodiment, the second scraping strip 117 is arranged to extend horizontally along the bottom of the cleaning device body 110, and the first scraping strip 116 can be of any shape as long as one end of the first scraping strip 116 is close to one side edge of the cleaning device body 110 and the other end of the first scraping strip 116 is close to the other side edge of the cleaning device body 110. The structure of the first scraping strip 116 can be similar to that of the second scraping strip 117 in the above-mentioned embodiment, which will not be described herein.

[0100] In other embodiments, the first scraping strip 116 and the second scraping strip 117 are both arranged to extend horizontally along the bottom of the cleaning device body 110. At least one of the first scraping strip 116 and the second scraping strip 117 can be of a straight line shape, a wavy line shape, or the like, which will not be limited herein.

[0101] At least a portion of the second scraping strip 117 close to the surface to be cleaned or away from the bottom of the cleaning device 100 is of a flexible or soft material (not shown in the figure). For example, at least a portion of the second scraping strip 117 close to the surface to be cleaned is of a soft scraping strip, and the portion of the second scraping strip 117 away from the surface to be cleaned or close to the bottom of the cleaning device 100 is of a hard material (not shown in the figure); or, the second scraping strip 117 is entirely of a soft scraping strip. When the second scraping strip 117 is at least partially or entirely of a soft material, the soft material portion can be deformed to avoid large hard dirt and garbage into the working area of the first liquid inlet portion 1121 during the movement of the cleaning device 100. The first scraping strip 116 can be of a hard scraping strip; or, the first scraping strip 116 can be at least partially of a soft scraping strip; or, the first scraping strip 116 can be of a combination of a hard scraping strip and a soft scraping strip, or the like. The soft scraping strip material and the hard scraping strip material can be selected as needed, which will not be limited herein. By arranging the second scraping strip 117 to be of a soft scraping strip at least towards one side of the surface to be cleaned, sand and the like can be directly swept into the liquid inlet channel 118 and then into the first liquid inlet portion 1121, thereby improving the cleaning efficiency.

[0102] In another embodiment, the first and second blades 116 and 117 can be hard blades, and in the first or second motion state, the first and second blades 116 and 117 are in close contact with or slightly spaced apart from the surface to be cleaned. This arrangement is suitable for the case where the surface to be cleaned is relatively flat and has no large particles of garbage. The two blades can be understood as only providing boundaries for the liquid inlet channel 118.

[0103] Referring to FIGS. 18 and 19, FIG. 18 is a schematic cross-sectional view of a third embodiment of the cleaning device of the present disclosure, and FIG. 19 is a schematic view of structure B in FIG. 18. In combination with FIGS. 2, 12, 15 and 16, in some embodiments, the first liquid inlet portion 1121 gradually decreases in cross-sectional area parallel to the surface to be cleaned from close to the surface to be cleaned to far from the surface to be cleaned. That is, the first liquid inlet portion 1121 is arranged in a gradually decreasing shape, such as close to the surface to be cleaned, the first liquid inlet portion 1121 has a large cross-sectional area parallel to the surface to be cleaned, and far from the surface to be cleaned, the first liquid inlet portion 1121 has a small cross-sectional area parallel to the surface to be cleaned. Through the above arrangement, the driving mechanism 130 can generate a large suction force at the end of the first liquid inlet portion 1121 far from the surface to be cleaned, thereby improving the speed of the external fluid flowing into the first liquid inlet portion 1121 and improving the cleaning efficiency.

[0104] Specifically, the first liquid inlet portion 1121 includes a first liquid inlet port 11212 far from the surface to be cleaned and a second liquid inlet port 11213 close to the surface to be cleaned. The first liquid inlet port 11212 and the second liquid inlet port 11213 are connected by at least one smooth transition zone 11211. The port area of the first liquid inlet port 11212 is smaller than the port area of the second liquid inlet port 11213. The smooth transition zone 11211 helps the dust-carrying water flow to move transversely to the first liquid inlet portion 1121. The above-mentioned smooth transition zone 11211 can be but is not limited to one and two, etc. When the smooth transition zone 11211 is one, the smooth transition zone 11211 can be located on the left side or the right side of the first liquid inlet portion 1121, etc. When the smooth transition zone 11211 is two, the angles between the two smooth transition zones 11211 and the surface to be cleaned can be the same or different, depending on the arrangement position of the first liquid inlet portion 1121. For example, the angle between one smooth transition zone 11211 and the surface to be cleaned can be greater than 0 degrees and less than or equal to 45 degrees. The angle between the other smooth transition zone 11211 and the surface to be cleaned can be greater than or equal to 60 degrees and less than 90 degrees.

[0105] In one embodiment, the second dust box inlet 12112 is in communication with the first liquid inlet port 11212 of the first liquid inlet portion 1121. The first liquid inlet port 11212 can be disposed at a position offset from the lateral center. The second liquid inlet port 11213 of the first liquid inlet portion 1121 is located at the bottom of the cleaning device 100 and adjacent to the surface to be cleaned. Two smooth transition zones 11211 are formed from the second liquid inlet port 11213 to the first liquid inlet port 11212, with the two smooth transition zones 11211 being respectively located at the lateral sides of the first liquid inlet port 11212. That is, the first liquid inlet port 11212, the two smooth transition zones 11211, and the second liquid inlet port 11213 form an irregular horn-like configuration in the shape of a trapezoid. Of course, the first liquid inlet port 11212 can also be disposed at the approximate lateral center of the first liquid inlet portion 1121, and the first liquid inlet port 11212 and the second liquid inlet port 11213 can be connected by two smooth transition zones 11211 that are approximately symmetric in the lateral direction.

[0106] Thus, the approximately closed liquid inlet flow channel 118 and the first liquid inlet portion 1121 cooperate to gradually decrease the cross-sectional area in a direction away from the surface to be cleaned, and at least one smooth transition zone 11211, to further increase the liquid flow rate through the first liquid inlet portion 1121 into the filtering mechanism 120, thereby further effectively improving the cleaning effect.

[0107] In some embodiments, at least one of the first scraping strip 116 and the second scraping strip 117 is disposed at the bottom of the cleaning device body 110 or the bottom of the filtering mechanism 120. For example, both the first scraping strip 116 and the second scraping strip 117 are disposed at the bottom of the cleaning device body 110; or both the first scraping strip 116 and the second scraping strip 117 are disposed at the bottom of the filtering mechanism 120; or the first scraping strip 116 is disposed at the bottom of the cleaning device body 110 and the second scraping strip 117 is disposed at the bottom of the filtering mechanism 120; or the first scraping strip 116 is disposed at the bottom of the filtering mechanism 120 and the second scraping strip 117 is disposed at the bottom of the cleaning device body 110. The first liquid inlet portion 1121 is disposed at the bottom of the cleaning device body 110 or the bottom of the filtering mechanism 120. For example, the first liquid inlet portion 1121 is disposed at the bottom of the cleaning device body 110; or the first liquid inlet portion 1121 is disposed at the bottom of the filtering mechanism 120. The above-described positions of the first scraping strip 116, the second scraping strip 117, and the first liquid inlet portion 1121 can be selected according to actual needs, and are not limited herein.

[0108] In one embodiment, the first scraping strip 116 and / or the second scraping strip 117 can be detachably connected to the cleaning device body 110 or the bottom of the filtering mechanism 120, so as to facilitate replacement and disassembly, etc. Since the first scraping strip 116 and the second scraping strip 117 are both consumable parts, they need to be replaced after a period of use. If the first scraping strip 116 and / or the second scraping strip 117 are arranged at the bottom of the filtering mechanism 120, they can be conveniently disassembled by taking out the filtering mechanism 120. However, since the liquid inlet 112, the dust box inlet portion 1211, etc. on the filtering mechanism 120 need to meet certain sealing requirements, the contact and friction of the first scraping strip 116 and / or the second scraping strip 117 arranged on the filtering mechanism 120 with the surface to be cleaned can cause vibration of the filtering mechanism 120 relative to the cleaning device body 110, thereby reducing the sealing effect mentioned above.

[0109] If the first scraping strip 116 and / or the second scraping strip 117 are arranged on the bottom shell of the cleaning device body 110, although the above-mentioned sealing problems can be largely reduced, it can be inconvenient for the user to replace them, as the user needs to turn over the cleaning device body 110 which has a relatively large weight. Therefore, in actual application, the arrangement position of the first scraping strip 116 and the second scraping strip 117 can be comprehensively considered according to the material properties, replacement frequency, and influence on the sealing performance of the cleaning device 100, etc., and is not specifically limited here.

[0110] In one embodiment, the first scraping strip 116 and / or the second scraping strip 117 can be a continuous scraping strip, i.e. the scraping strip is integrally formed. The first scraping strip 116 and / or the second scraping strip 117 can also be discontinuous as shown in FIG. 15 and FIG. 16. The first scraping strip 116 and the second scraping strip 117 at least include two or more scraping pieces, and the adjacent scraping pieces are disconnected. When there is a large-size garbage or obstacle, each scraping piece can be deformed independently. The end of the scraping strip / scraping piece close to the surface to be cleaned is defined as the first end, and the end close to the bottom of the cleaning device 100 is defined as the second end. For the discontinuous scraping piece, the second end can be arranged on a continuous mounting portion (not shown in the figure). The mounting portion is used to detachably mount the scraping strip to the bottom of the cleaning device 100 or the bottom of the filtering mechanism 120.

[0111] In one embodiment, the bottom of the cleaning device 100 or the bottom of the filtering mechanism 120 is provided with a slot (not shown in the figure). The second end of the scraping strip or the scraping piece can be inserted transversely and fixed vertically in the slot. When it is necessary to replace the scraping strip or the scraping piece, it can be removed transversely from the slot.

[0112] When the cleaning device 100 is cleaning the target bottom wall 410 or the target side wall 420, i.e. the cleaning device 100 is cleaning the surface to be cleaned, at least one of the first wiper strip 116 and the second wiper strip 117 has a certain degree of contact interference with the surface to be cleaned, or at least one of the first wiper strip 116 and the second wiper strip 117 is in contact with the surface to be cleaned. That is, from the side of the cleaning device 100, at least one of the first wiper strip 116 and the second wiper strip 117 extends from the bottom of the cleaning device 100 to the surface to be cleaned beyond or substantially flush with the contact surface of the track 173 or the walking assembly 170 with the surface to be cleaned. That is, at least one of the first wiper strip 116 and the second wiper strip 117 extends beyond or substantially flush with the bottom profile of the cleaning device 100. In actual process, if the first ends of the first wiper strip 116 and the second wiper strip 117 are both soft material, they can both form contact interference with the surface to be cleaned, thereby generating a more optimal closed liquid inlet channel 118. If the first end of the second wiper strip 117 is soft material and the first end of the first wiper strip 116 is hard material, the second wiper strip 117 can be arranged to have contact interference with the surface to be cleaned, and the first wiper strip 116 can be arranged to just contact or have a small gap with the surface to be cleaned, so as to prevent the hard first wiper strip 116 from forming a hard contact with the surface to be cleaned, which can cause noise, damage the first wiper strip 116 or the surface to be cleaned.

[0113] Please refer to FIG. 20, which is a schematic diagram of different liquid inlet channels in the cleaning device of the present disclosure. In combination with FIG. 2, FIG. 12 and FIG. 15, the liquid inlet channel 118 can be formed in other ways in addition to being formed by the first scraping strip 116 and the second scraping strip 117. As shown in FIG. 20(2), a cleaning member 151 is arranged at the front of the first liquid inlet portion 1121, and the first scraping strip 116 is arranged at the back of the first liquid inlet portion 1121, i.e., the cleaning member 151 and the first scraping strip 116 form the liquid inlet channel 118, and the rotation of the cleaning member 151 can improve the external fluid suction efficiency. As shown in FIG. 20(3), one cleaning member 151 is arranged at the front of the first liquid inlet portion 1121, and another cleaning member 151 is arranged at the back of the first liquid inlet portion 1121, and both cleaning members 151 are arranged along the bottom of the main body 110 of the cleaning device, and the spacing between the two adjacent cleaning members 151 is small, thereby forming the liquid inlet channel 118. As shown in FIG. 20(4), the second scraping strip 117 is arranged at the front of the first liquid inlet portion 1121, and the first scraping strip 116 is arranged at the back of the first liquid inlet portion 1121, i.e., the second scraping strip 117 and the first scraping strip 116 form the liquid inlet channel 118, and a cleaning member 151 can also be arranged in front of the second scraping strip 117. As shown in FIG. 20(1), at least one second scraping strip 117 and one cleaning member 151 are arranged from front to back at the bottom of the cleaning device 100, wherein the second scraping strip 117 and the cleaning member 151 are arranged close to the front and back of the first liquid inlet portion 1121, thereby also forming the liquid inlet channel 118, and another cleaning member 151 can also be arranged in front of the second scraping strip 117. Thus, the projection of the first liquid inlet portion 1121 on the surface to be cleaned is at least partially located between at least two of the four cleaning members 151, the first scraping strip 116 and the second scraping strip 117.

[0114] When the existing cleaning device 100 needs to be docked to the shore after completing the work or in other situations, the bottom of the main body 110 of the cleaning device 100 is tightly attached to the target side wall 420, part of the cleaning device 100 is exposed to the water surface 300, and the driving mechanism 130 (such as the main water pump 131) continues to work, so that the cleaning device 100 remains in the wall-attached state. The above-mentioned mode requires the main water pump 131 to work continuously, which consumes a large amount of electric energy.

[0115] Please refer to FIG. 21, which is a partial diagram of the fifth embodiment of the cleaning device of the present disclosure. In combination with FIG. 2, FIG. 12 and FIG. 15, in some embodiments, the cleaning device 100 comprises a mode switching member 140. The mode switching member 140 is used to adjust the force received by the cleaning device 100 in the vertical direction, which can include the buoyancy of the cleaning device 100 in the vertical direction. The mode switching member 140 can comprise a buoyancy adjusting assembly (not shown in the figure). The buoyancy adjusting assembly can be used to adjust the size of the buoyancy of the cleaning device 100 in the vertical direction.

[0116] Specifically, the buoyancy adjusting assembly includes a buoyancy chamber 141 and a buoyancy chamber pump 142. The buoyancy chamber 141 can be used to contain liquid and / or gas. The buoyancy chamber pump 142 is connected with the buoyancy chamber 141. The buoyancy chamber pump 142 can be used to adjust the volume of the liquid and / or gas in the buoyancy chamber 141. By adjusting the volume of the liquid and / or gas in the buoyancy chamber 141 through the buoyancy chamber pump 142, the magnitude of the buoyancy force acting on the cleaning device 100 in the vertical direction is changed, so as to switch the cleaning device 100 between the first motion state and the third motion state.

[0117] Thus, for the cleaning device 100 that performs the cleaning work on the target bottom wall 410 and / or the target side wall 420, when the work is completed or other conditions requiring the cleaning device 100 to float to the water surface 300, the cleaning device 100 is drained through the buoyancy chamber 141, so that the cleaning device 100 floats to the water surface 300 and is in a floating state on the water surface 300, facilitating the user to fish the cleaning device 100 without the main water pump 131 continuously working, achieving the unpowered water surface 300 stoppage and saving energy consumption. The cleaning device 100 can float on the water surface 300 at the shore or at any position on the water surface 300, and the user does not need to search for and fish the cleaning device 100 under the water, but directly takes the cleaning device 100 from the water surface 300, which is convenient and fast.

[0118] In some embodiments, the front upper portion of the cleaning device body 110 is provided with a device air inlet 1191, so that the cleaning device 100 can quickly communicate with the atmosphere when the cleaning device 100 is exposed to the water surface 300. The device air inlet 1191 is used for air intake or air exhaust, etc. The bottom of the cleaning device body 110 is provided with a device water inlet 1192. The device water inlet 1192 is used for water intake or water exhaust, etc. Overall, the device water inlet 1192 is located below and behind the device air inlet 1191. The buoyancy chamber 141 is provided with a buoyancy chamber air inlet 1414 and a buoyancy chamber water inlet 1415. The buoyancy chamber air inlet 1414 is used for air intake or air exhaust, etc. The buoyancy chamber water inlet 1415 is used for water intake or water exhaust, etc. The device air inlet 1191, the buoyancy chamber 141, the buoyancy chamber pump 142, and the device water inlet 1192 are sequentially connected through connecting pipes.

[0119] When the cleaning device 100 is switched from the third motion state to the first motion state, the cleaning device 100 at least partially floats on the water surface 300, the device air inlet 1191 is also located above the water surface 300, the device water inlet 1192 is located below the water surface 300, and the buoyancy chamber pump 142 starts to suck water in the normal direction. The water from the device water inlet 1192 at the bottom of the cleaning device body 110 is sucked into the buoyancy chamber 141 through the connecting pipe and the buoyancy chamber water inlet 1415 by the buoyancy chamber pump 142, and the excess air in the buoyancy chamber 141 is discharged from the device air inlet 1191 of the cleaning device body 110 through the connecting pipe from the buoyancy chamber air inlet 1414.

[0120] When the cleaning device 100 is switched from the first motion state to the third motion state, the cleaning device 100 first moves to a position where the device air inlet 1191 is exposed to the water surface 300, such as a position where the pool target side wall 420 is close to the water surface, and the floating cavity pump 142 is reversed to start inhaling. Air is sucked into the floating cavity 141 by the floating cavity pump 142 from the device air inlet 1191 of the cleaning device main body 110 through the connecting pipe and the floating cavity air inlet 1414, and the water inside the floating cavity 141 is discharged from the device water inlet 1192 of the cleaning device main body 110 through the connecting pipe from the floating cavity water inlet 1415.

[0121] Generally, the cleaning device 100 can be switched from the first motion state to the third motion state through the second motion state, and the second motion state includes moving the cleaning device 100 along the pool wall to the waterline. When the cleaning device 100 moves upward from the bottom of the pool to the waterline, the floating cavity air inlet 1414 or the device air inlet 1191 connected with the floating cavity air inlet 1414 can be exposed to the water surface 300 first, so that external air can enter the floating cavity 141. During the above process, the floating cavity air inlet 1414 is above the water surface 300, and it is necessary to ensure that the floating cavity 141 is full of air or the air volume in the floating cavity 141 reaches a preset volume, so that the cleaning device 100 can be switched to the third motion state or the water surface cleaning posture and kept. During the inflation process of the floating cavity 141, the posture of the cleaning device 100 will change. During the inflation change process of the floating cavity 141, the setting position of the device air inlet 1191 needs to ensure that the inflation volume in the floating cavity 141 is always above the water surface 300 before reaching the preset inflation volume. For example, the device air inlet 1191 can be arranged near the intersection of the front side and the top of the cleaning device 100, or on the handle 1104 of the cleaning device 100, or on the left or right side of the cleaning device 100 close to the intersection of the front side and the top, etc.

[0122] Referring to FIG. 22 to FIG. 24, FIG. 22 is a first partial schematic view of a fifth embodiment of the cleaning device of the present disclosure; FIG. 23 is a partial bottom view of the fifth embodiment of the cleaning device of the present disclosure; and FIG. 24 is a structural schematic view of a floating cavity in the cleaning device of the present disclosure. In combination with FIG. 2, FIG. 12 and FIG. 15. In some embodiments, the cleaning device 100 comprises a control box 160. The control box 160 is arranged at a rear position of the cleaning device main body 110. The mode switching member 140 comprises a floating cavity 141 and a floating cavity pump 142 in communication with the floating cavity 141. The floating cavity 141 is arranged between the filtering mechanism 120 and the control box 160. The control box 160 is a sealed closed structure, and the floating cavity pump 142 is arranged in the control box 160, thereby reducing the influence of external fluid on the floating cavity pump 142 and improving the service life of the floating cavity pump 142. The control box 160 can also accommodate a main control board (not shown in the figure) and the like. By arranging the floating cavity 141 between the filtering mechanism 120 and the control box 160, the space occupation of the cleaning device 100 can be reduced, the space utilization can be improved, and the balance of the buoyancy of the entire cleaning device 100 can be adjusted.

[0123] In some embodiments, the floating cavity 141 can comprise a first floating cavity 1411, a second floating cavity 1412 and an intermediate floating cavity 1413. One end of the intermediate floating cavity 1413 is in communication with the first floating cavity 1411. The other end of the intermediate floating cavity 1413 is in communication with the second floating cavity 1412. At least a portion of the first floating cavity 1411 is located on the side of the filtering mechanism 120, and at least another portion of the first floating cavity 1411 is located on the side of the control box 160, wherein the first floating cavity 1411 at least longitudinally spans at least part of the filtering mechanism 120 and at least part of the control box 160 and the like. At least a portion of the second floating cavity 1412 is located on the side of the filtering mechanism 120, and at least another portion of the second floating cavity 1412 is located on the side of the control box 160, wherein the second floating cavity 1412 at least longitudinally spans at least part of the filtering mechanism 120 and at least part of the control box 160 and the like. The intermediate floating cavity 1413 is located between the filtering mechanism 120 and the control box 160.

[0124] In some embodiments, the first floating cavity 1411 and the second floating cavity 1412 are symmetrically arranged relative to the intermediate floating cavity 1413. The first floating cavity 1411 and the second floating cavity 1412 are respectively provided with a floating cavity air inlet 1414 at an upper position of a front end thereof. The first floating cavity 1411 and the second floating cavity 1412 are respectively provided with a floating cavity water inlet 1415 at a lower position of a rear end thereof. The floating cavity 141 is arranged in an H shape.

[0125] In some embodiments, the cleaning device 100 comprises a three-way pipe (not shown in the figure). The float chamber pump 142 has two connection ends (not shown in the figure). One connection end is connected with the device air inlet 1191, and the other connection end is connected with one communication port of the three-way pipe. The remaining two communication ports of the three-way pipe are respectively connected with the two float chamber air inlets 1414 of the float chamber 141. The device water inlet 1192 has two connection heads. The two connection heads of the device water inlet 1192 are respectively connected with the two float chamber water inlets 1415 of the float chamber 141.

[0126] When the cleaning device 100 sinks from the water surface 300 to the water bottom, i.e. when it is converted from the third motion state to the first motion state, the cleaning device 100 floats on the water surface 300, and the float chamber pump 142 rotates in the forward direction to start sucking water. The water from the device water inlet 1192 at the bottom of the cleaning device 100 is sucked into the float chamber 141 through the connecting pipe and the float chamber water inlet 1415 by the float chamber pump 142, and the excess air inside the float chamber 141 is discharged from the float chamber air inlet 1414 through the connecting pipe, the three-way pipe, and the device air inlet 1191 of the cleaning device 100.

[0127] When the cleaning device 100 starts to rise from the water bottom to the water surface 300, i.e. when it is converted from the first motion state to the third motion state, the cleaning device 100 first moves to a position where the device air inlet 1191 is exposed to the water surface 300, such as moving towards the water line on the side wall of the pool, until the device air inlet 1191 is exposed to the water surface 300. The float chamber pump 142 reverses to start sucking air. The air from the device air inlet 1191 at the top of the cleaning device 100 is sucked into the float chamber 141 through the connecting pipe, the three-way pipe, and the float chamber air inlet 1414 by the float chamber pump 142, and the excess water inside the float chamber 141 is discharged from the float chamber water inlet 1415 through the connecting pipe and the device water inlet 1192 of the cleaning device 100.

[0128] Referring to FIG. 25 and FIG. 26, FIG. 25 is a partial bottom view of a sixth embodiment of the cleaning apparatus of the present disclosure, and FIG. 26 is a partial bottom view of a seventh embodiment of the cleaning apparatus of the present disclosure. In some embodiments, the cleaning apparatus 100 further comprises a traveling assembly 170 and at least one cleaning element 151 disposed laterally on the bottom of the cleaning apparatus 100, in combination with FIG. 2, FIG. 12, FIG. 15 and FIG. 22. The traveling assembly 170 is disposed on the bottom of the cleaning apparatus body 110 for driving the cleaning apparatus body 110 to move along the target bottom wall 410 or the target side wall 420. The traveling assembly 170 can comprise a first traveling wheel 171 and a second traveling wheel 172 disposed on the front and back of the cleaning apparatus 100, and a track 173 sleeved on the first traveling wheel 171 and the second traveling wheel 172. The traveling assembly 170 is disposed in the longitudinal direction of the cleaning apparatus 100 as a whole. At least two cleaning elements 151 are disposed laterally on the front and back of the bottom of the cleaning apparatus body 110. For example, at least one cleaning element 151 is disposed laterally on the front end of the bottom of the cleaning apparatus body 110, at least one cleaning element 151 is disposed laterally on the back end of the bottom of the cleaning apparatus body 110, and the cleaning element 151 at least partially protrudes out of the profile of the cleaning apparatus body 110. When the cleaning apparatus 100 performs underwater cleaning work, the cleaning element 151 is in rotational contact with the surface to be cleaned for cleaning the surface to be cleaned. When the cleaning apparatus 100 performs work on the water surface 300, the at least one cleaning element 151 rotates and rolls the garbage on the water surface 300 into the second liquid inlet portion 1122.

[0129] In one embodiment, as shown in FIG. 25 and FIG. 26, the first traveling wheel 171 is the front wheel of the cleaning apparatus 100, and the second traveling wheel 172 is the back wheel of the cleaning apparatus 100, both of which are disposed on the two sides of the cleaning apparatus 100. The length of the cleaning element 151 on the front of the cleaning apparatus 100 covers at least 80%, or even 90%, of the lateral width of the bottom of the cleaning apparatus 100. And the cleaning element 151 on the front is located in front of the first traveling wheel 171 on the left and right sides of the cleaning apparatus 100 as a whole.

[0130] In another embodiment, the length of the cleaning element 151 on the back of the cleaning apparatus 100 covers at least 80%, or even 90%, of the lateral width of the bottom of the cleaning apparatus 100, and the cleaning element 151 on the back is located behind the second traveling wheel 172 on the left and right sides of the cleaning apparatus 100 as a whole.

[0131] From another perspective, along the longitudinal direction of the cleaning apparatus 100, the projection of the cleaning element 151 on the front of the cleaning apparatus 100 and / or the cleaning element 151 on the back of the cleaning apparatus 100 in the longitudinal direction does not coincide with the projection of the entire traveling assembly 170 in the longitudinal direction. Further, the projection of the rotational axis of the cleaning element 151 on the front of the cleaning apparatus 100 and / or the cleaning element 151 on the back of the cleaning apparatus 100 in the longitudinal direction does not coincide with the projection of the entire traveling assembly 170 in the longitudinal direction.

[0132] Through the above arrangement, the effective cleaning area of the cleaning member 151 is significantly increased during one trip of the cleaning device 100, and thus the increase of the single cleaning area can reduce the number of trips and improve the cleaning efficiency when the cleaning device 100 cleans along the planned path, such as the bow-shaped path or the inverted U-shaped path.

[0133] In some embodiments, the cleaning member 151 is flush with or protrudes from one side of the cleaning device body 110 at both ends, so that the cleaning member 151 can span as much as possible in the width direction of the bottom of the cleaning device body 110 or be greater than the width direction of the bottom of the cleaning device body 110, thereby effectively increasing the effective cleaning range of the cleaning member 151.

[0134] In one embodiment, the cleaning member 151 at the front end of the bottom of the cleaning device body 110 is flush with the two sides of the cleaning device body 110 at both ends. In another embodiment, the cleaning member 151 at the front end of the bottom of the cleaning device body 110 is flush with the two sides of the cleaning device body 110 at both ends; at the same time, the cleaning member 151 at the rear end of the bottom of the cleaning device body 110 is flush with the two sides of the cleaning device body 110 at both ends, and the walking assembly 170 is arranged between the at least two cleaning members 151.

[0135] The walking assembly 170 can be in driving connection with the cleaning member 151, that is, the cleaning member 151 moves with the walking assembly 170. Alternatively, the cleaning member 151 is powered by an independent driving assembly, so that the walking assembly 170 and the cleaning member 151 work independently.

[0136] The walking assembly 170 can drive the cleaning device 100 to move along the target bottom wall 410, along the target side wall 420, from the target bottom wall 410 to the target side wall 420, and from the target side wall 420 to the target bottom wall 410. Due to the arrangement of the at least two cleaning members 151, the length of the walking assembly 170 in the longitudinal direction of the cleaning device 100 is reduced. When the cleaning device 100 converts from the target bottom wall 410 to the target side wall 420, the walking assembly 170 with reduced length is in contact with the target side wall 420 later than the cleaning member 151, so that the walking assembly 170 cannot provide auxiliary power for the above conversion process, and the cleaning member 151 is always in a rotating state during the process, and the cleaning member 151 can act as a power member to assist the cleaning device 100 to convert from the target bottom wall 410 to the target side wall 420. The driving mechanism 130 can be turned on or off according to actual needs to enable the cleaning device 100 to smoothly complete the above position conversion. Similarly, when the cleaning device 100 converts from the target side wall 420 to the target bottom wall 410, the rotation of the cleaning member 151 and the control of the driving mechanism 130 can also be used to achieve the conversion.

[0137] In some embodiments, the cleaning member 151 comprises a roller brush shaft (not shown) and blades (not shown) extending radially outward from the roller brush shaft. The blades can be linear or non-linear. The blades can be arranged in segments along the length of the roller brush shaft. Adjacent blades can be arranged in a helical pattern along the length of the roller brush shaft. Alternatively, adjacent blades can be arranged in a circular pattern along the length of the roller brush shaft.

[0138] When the cleaning device 100 is performing pool floor or pool wall cleaning, all of the blades of the cleaning member 151 are submerged in water. The cleaning member 151 cleans the pool floor or pool wall and gathers the debris into the liquid inlet 112. When the cleaning device 100 is performing surface cleaning, at least some of the blades of the cleaning member 151 are submerged in the water surface 300. The at least some of the blades clean the water surface 300 and generate turbulence, and gather the debris into the second liquid inlet 1122.

[0139] Referring to FIG. 27 and FIG. 28, FIG. 27 is a schematic diagram of the filtering mechanism of the eighth embodiment of the cleaning device of the present disclosure, and FIG. 28 is a cross-sectional view of the filtering mechanism of the eighth embodiment of the cleaning device of the present disclosure. In combination with FIG. 2, FIG. 12, FIG. 15 and FIG. 22, the dust box compartment 1152 is configured to accommodate the dust box 121. The dust box compartment 1152 comprises a plurality of compartment walls. The compartment wall close to the liquid outlet 111 or the driving mechanism 130 is defined as the water outlet wall. The water outlet wall can be provided with a grid-shaped or mesh-shaped water outlet wall opening for providing an open channel for water flow from the dust box compartment 1152 to the driving mechanism 130.

[0140] In some embodiments, the cleaning device 100 further comprises an auxiliary filtering member 126. The auxiliary filtering member 126 has the same function as the dust box 121, i.e. filtering. The auxiliary filtering member 126 can cover the water outlet wall opening to further filter the water flow after being filtered by the dust box 121. In some embodiments, the filter mesh of the auxiliary filtering member 126 has a smaller filter mesh size than the filter mesh of the dust box 121, i.e. the auxiliary filtering member 126 has a higher filtering efficiency. The filter mesh of the auxiliary filtering member 126 has a higher filtering level than the filter mesh of the dust box 121, and can filter finer debris, thereby improving the cleaning effect of the cleaning device 100.

[0141] In some embodiments, the auxiliary filter 126 comprises an auxiliary filter support 1261 and an auxiliary filter screen (not shown in the figures). The auxiliary filter screen is arranged on the auxiliary filter support 1261. The auxiliary filter screen is used to filter garbage and the like. The auxiliary filter support 1261 can have various arrangements. In a specific embodiment, the auxiliary filter support 1261 is detachably arranged on the side of the dust box 121 close to the opening of the water outlet wall, facilitating the installation and removal of the auxiliary filter 126 and the like, so that the user can install and remove the auxiliary filter 126 according to different needs of the filtering degree and the like. The detachable manner can be, but is not limited to, buckle connection, magnetic attraction connection, bolt connection and the like. In an embodiment, the dust box 121 comprises a frame forming a main body of the dust box and a filter screen covering the frame. The auxiliary filter support 1261 is fixedly or detachably arranged on the dust box frame. The auxiliary filter 126 can optionally cover the entire surface or at least part of the surface of the dust box 121 close to the driving mechanism 130 or close to the water outlet wall, and the projection of the at least part of the surface on the central plane α at least partially or entirely covers the projection of the opening of the water outlet wall on the central plane α. Of course, the auxiliary filter support 1261 can also be fixedly arranged on the dust box 121, and the auxiliary filter screen is detachably mounted on the auxiliary filter support 1261. The fixed manner can be, but is not limited to, welding, one-piece forming and the like.

[0142] In another embodiment, the auxiliary filter support 1261 is fixedly or detachably arranged on the water outlet wall of the dust box bin 1152, and the auxiliary filter screen is fixedly or detachably mounted on the auxiliary filter support 1261. The auxiliary filter support 1261 can be arranged on the side of the water outlet wall close to the dust box 121, i.e. arranged in the dust box bin 1152; or arranged on the side of the water outlet wall close to the driving mechanism 130, i.e. arranged outside the dust box bin 1152.

[0143] In some embodiments, the cleaning device 100 further comprises a wifi communication module (not shown in the figures). The wifi communication module is arranged on the upper part of the cleaning device 100. The specific position of the wifi communication module is not limited, and when the cleaning device 100 floats to the water surface 300, the wifi communication module can be located above the water surface 300. When the cleaning device 100 floats to the water surface 300, the wifi communication module is exposed above the water surface 300, so that the cleaning device 100 and the external terminal can communicate through the wifi communication module, and signal interaction with the external terminal can be realized. For example, the cleaning device 100 can send state information to the external terminal, and the state information can be work task completion, device abnormal information and the like. The cleaning device 100 can also receive signals from the external terminal, such as start signal, working mode information and the like. The external terminal can be a mobile phone terminal, a base station and the like.

[0144] Specifically, the WiFi communication module can be arranged at a front end position of the upper portion of the cleaning device 100, such as the handle 1104 of the cleaning device 100.

[0145] For the convenience of description, a plane in which the rotation shafts of the first and second traveling wheels 171 and 172 of the traveling assembly 170 of the cleaning device 100 are located is defined as a longitudinal plane of the cleaning device 100. A plane that is perpendicular to the longitudinal plane and parallel to the extension direction of the rotation shafts of the first and second traveling wheels 171 and 172 and has an equal distance to the rotation shafts of the first and second traveling wheels 171 and 172 is defined as a central plane of the cleaning device 100. The central plane α is arranged opposite to the front and rear portions of the cleaning device 100.

[0146] Referring to FIGS. 29 and 30, FIG. 29 is a structural schematic diagram of a ninth embodiment of the cleaning device of the present disclosure, and FIG. 30 is a cross-sectional schematic diagram of the ninth embodiment of the cleaning device of the present disclosure. In some embodiments, the cleaning device 100 includes a first sub-drainage pipeline 1101 and a second sub-drainage pipeline 1102. The first sub-drainage pipeline 1101 and the second sub-drainage pipeline 1102 are connected to the filter mechanism 120 through the main water pump inlet 132 of the main water pump 131. The outlet 111 further includes a first sub-drainage port 1111 and a second sub-drainage port 1112. The first sub-drainage pipeline 1101 forms the first sub-drainage port 1111 at the end thereof. The second sub-drainage pipeline 1102 forms the second sub-drainage port 1112 at the end thereof. The first sub-drainage pipeline 1101 and / or the second sub-drainage pipeline 1102 can be in openable and closable communication. That is, the first sub-drainage pipeline 1101 has two states of being open or closed. The second sub-drainage pipeline 1102 has two states of being open or closed. For example, the first sub-drainage pipeline 1101 is open, and the second sub-drainage pipeline 1102 is closed; or the first sub-drainage pipeline 1101 is closed, and the second sub-drainage pipeline 1102 is open; or both the first sub-drainage pipeline 1101 and the second sub-drainage pipeline 1102 are open.

[0147] In some embodiments, the first sub-drainage port 1111 is located closer to the front portion of the cleaning device 100 than the second sub-drainage port 1112. The second sub-drainage port 1112 is located closer to the rear portion of the cleaning device 100 than the first sub-drainage port 1111, but is not limited thereto. Alternatively, the first sub-drainage port 1111 and the second sub-drainage port 1112 can be arranged side by side. Alternatively, the second sub-drainage port 1112 is located closer to the front portion of the cleaning device 100 than the first sub-drainage port 1111, and the like, which can be adjusted according to the structure of the cleaning device 100.

[0148] As an embodiment, the first sub-drainage port 1111 is located between the central plane a and the front of the cleaning device 100, that is, the first sub-drainage port 1111 is located at the front of the center of the cleaning device 100; the second sub-drainage port 1112 is located between the central plane a and the rear of the cleaning device 100, that is, the second sub-drainage port 1112 is located at the rear of the center of the cleaning device 100. Through the above-mentioned relative position between the first sub-drainage port 1111 and the second sub-drainage port 1112 and the cleaning device 100, when the first sub-drainage port 1111 and the second sub-drainage port 1112 are both opened, the uniformity of the pressure of the cleaning device 100 on the surface to be cleaned can be improved, thereby improving the cleaning efficiency of the cleaning device 100.

[0149] The first sub-drainage port 1111 and / or the second sub-drainage port 1112 are opened according to the angle of the cleaning device 100 and / or the current state of the cleaning device 100 under different operating conditions of the cleaning device 100. The angle of the cleaning device 100 can be the inclination angle of the cleaning device 100 relative to the horizontal plane, which can be obtained by a single or multiple angle detection devices arranged in the cleaning device 100; the current state of the cleaning device 100 can be a water surface state or an underwater state, etc., which can be determined by the current environment of the cleaning device 100 by the liquid entry detection assembly, the liquid level detection assembly, and the topography detection assembly. The liquid entry detection assembly is used to detect whether the cleaning device 100 has entered the liquid in the target area 400. The liquid level detection assembly is used to detect the liquid level of the current position of the cleaning device 100 when the liquid entry detection assembly detects that the cleaning device 100 has currently entered the liquid in the target area 400. The topography detection assembly is used to detect the topography of the surface to be cleaned at the bottom of the cleaning device 100 to adjust the operating posture of the cleaning device 100.

[0150] When the cleaning device 100 performs water surface cleaning work, the second sub-drainage port 1112 is opened to form a cleaning water flow channel and / or provide part of the forward propulsion, and the first sub-drainage port 1111 is closed to avoid generating downward pressure to press the front of the cleaning device 100 into the water, affecting the normal work of the liquid inlet part 112.

[0151] When the cleaning device 100 performs underwater cleaning work, the first sub-drainage port 1111 is opened and the second sub-drainage port 1112 is closed or the water flow of the second sub-drainage port 1112 is reduced through the current action of the cleaning device 100. For example, when the cleaning device 100 runs on the pool bottom, the material of the pool bottom can be cement, ceramic tile, PVC, etc., and the topography of the pool bottom can include inclined uphill or downhill, transition from horizontal to inclined surface, and transition from inclined surface to horizontal surface, convex or concave obstacles, etc. When the cleaning device 100 performs arch or back-shaped path cruise cleaning on the pool bottom, travels along the inclined pool bottom, etc., as shown in FIG. 30, since the first sub-drainage port 1111 is located at the front of the cleaning device 100, it can provide sufficient downward pressure for various operations of the cleaning device 100, avoiding the cleaning device 100 tilting, affecting the normal walking and cleaning effect of the cleaning device 100.

[0152] As shown in FIG. 31, when the cleaning device 100 walks on the pool bottom and encounters a step and needs to clean the step surface, the cleaning device 100 can also open the first sub-drainage port 1111 when climbing the vertical surface of the step to provide stronger wall climbing ability, especially when the cleaning device 100 transitions from the vertical surface of the step to the horizontal surface, opening the first sub-drainage port 1111 located at the front of the cleaning device 100 can make the cleaning device 100 transition from the vertical state to the horizontal state faster, improving the operation efficiency. As shown in FIG. 32, when the cleaning device 100 runs from the horizontal surface to the downhill surface, opening the first sub-drainage port 1111 can avoid the cleaning device 100 from detaching from the downhill surface under the action of inertia and then tilting and turning over. When the cleaning device 100 runs from the horizontal surface to the uphill surface and runs on the uphill surface, opening the first sub-drainage port 1111 can avoid the cleaning device 100 from tilting and turning over on the uphill surface. As shown in FIG. 33, when the cleaning device 100 runs from the uphill surface to the horizontal surface, opening the first sub-drainage port 1111 can avoid the cleaning device 100 from detaching from the horizontal surface while still retaining the uphill inclined posture under the action of inertia, etc.

[0153] In some embodiments, the drainage direction of the first sub-drainage port 1111 is generally upward, for example, perpendicular to the longitudinal plane of the cleaning device 100, or has a certain degree of inclination angle with the central plane a of the cleaning device 100, such as within 30 degrees. In this embodiment, the reverse direction of the first sub-drainage port 1111 is generally parallel to the central plane a. The drainage direction of the second sub-drainage port 1112 is inclined to the direction opposite to the normal running direction of the cleaning device 100, for example, inclined backward to the central plane a of the cleaning device 100, and the inclination angle is between 25 degrees and 70 degrees.

[0154] In an embodiment, the first sub-drainage port 1111 can also be controlled to be opened according to that the inclination angle of the longitudinal plane of the cleaning device 100 relative to the horizontal plane is less than or equal to a predetermined angle threshold, where the predetermined angle threshold can be, for example, 60 degrees, but is not limited thereto. For example, when the cleaning device 100 is located on the target bottom wall 410, the horizontal plane is the target bottom wall 410, and the inclination angle of the longitudinal plane of the cleaning device 100 relative to the horizontal plane is less than or equal to the predetermined angle threshold, the opening of the first sub-drainage port 1111 can increase the acting force between the cleaning device 100 and the target bottom wall 410, so that the cleaning device 100 does not drift when moving or rotating on the target bottom wall 410 with small friction, improves the coverage rate of the movement of the cleaning device 100, and thus improves the cleaning effect and increases the cleaning efficiency; when the first sub-drainage port 1111 is located close to the front of the cleaning device 100, if the first sub-drainage port 1111 is opened, the front of the cleaning device 100 can also not be raised when the cleaning device 100 moves on the target bottom wall 410 with a slope, for example, uphill or downhill, so as to avoid the cleaning device 100 from turning over and improve the cleaning efficiency of the cleaning device 100.

[0155] When the inclination angle of the longitudinal plane of the cleaning device 100 relative to the horizontal plane is greater than or equal to the predetermined angle threshold, the second sub-drainage port 1112 can be opened. For example, when the cleaning device 100 is located on the target side wall 420, the horizontal plane is the target side wall 420, and the inclination angle of the longitudinal plane of the cleaning device 100 relative to the horizontal plane is greater than or equal to the predetermined angle threshold, the opening of the second sub-drainage port 1112 can not only increase the acting force between the cleaning device 100 and the target side wall 420, but also provide a horizontal thrust in the same direction as the running direction of the cleaning device 100. In the case that the filter mechanism 120 of the cleaning device 100 is blocked, resulting in a decrease in the drainage capacity of the second sub-drainage port 1112, the cleaning device 100 can still move upward on the target side wall 420 to climb near the waterline by relying on the thrust component in the same direction as the running direction of the cleaning device 100 provided by the second sub-drainage port 1112, thereby improving the success rate of the normal operation of the cleaning device 100 on the target side wall 420.

[0156] In some embodiments, when the inclination angle of the longitudinal plane of the cleaning device 100 relative to the horizontal plane is greater than or equal to the predetermined angle threshold, if it is detected that the cleaning device 100 has a tendency to turn over, the first sub-drainage port 1111 can be opened, for example, the second sub-drainage port 1112 can be switched to the first sub-drainage port 1111, or the water can be drained from the first sub-drainage port 1111 and the second sub-drainage port 1112 at the same time, etc. Whether the cleaning device 100 has a tendency to turn over can be identified by the topography detection assembly 196, or an acceleration sensor, a gyroscope, or other sensors provided on the cleaning device 100.

[0157] In some embodiments, the cleaning device 100 comprises a liquid discharge baffle 1103. The liquid discharge baffle 1103 can selectively close / open the first sub-liquid discharge pipe 1101 or the second sub-liquid discharge pipe 1102, thereby correspondingly closing / opening the first sub-liquid discharge port 1111 or the second sub-liquid discharge port 1112, i.e., the liquid discharge baffle 1103 can selectively open the first sub-liquid discharge port 1111 or the second sub-liquid discharge port 1112.

[0158] The liquid discharge baffle 1103 is arranged to be movable between a first position and a second position. In the first position, the liquid discharge baffle 1103 closes the first sub-liquid discharge port 1111 and opens the second sub-liquid discharge port 1112, and liquid is discharged out of the cleaning device 100 from the second sub-liquid discharge port 1112. In the second position, the liquid discharge baffle 1103 closes the second sub-liquid discharge port 1112 and opens the first sub-liquid discharge port 1111, and liquid is discharged out of the cleaning device 100 from the first sub-liquid discharge port 1111.

[0159] In an embodiment, a third position can be further included between the first position and the second position. When the liquid discharge baffle 1103 is in the third position, liquid discharged from the outlet of the main water pump 131 is partially discharged out of the cleaning device 100 from the first sub-liquid discharge port 1111 and partially discharged out of the cleaning device 100 from the second sub-liquid discharge port 1112. In this case, the first sub-liquid discharge port 1111 at the front of the cleaning device 100 and the second sub-liquid discharge port 1112 at the rear of the cleaning device 100 can both generate a downward pressure on the cleaning device 100 towards the surface to be cleaned, while the second sub-liquid discharge port 1112 can also generate a propelling force in the direction of travel of the cleaning device 100, facilitating smooth operation of the cleaning device 100 on the surface to be cleaned.

[0160] Specifically, the first sub-liquid discharge port 1111 is formed at the end of the first sub-liquid discharge pipe 1101, and the second sub-liquid discharge port 1112 is formed at the end of the second sub-liquid discharge pipe 1102. The rotation axis of the liquid discharge baffle 1103 can be arranged at the intersection of the first sub-liquid discharge pipe 1101 and the second sub-liquid discharge pipe 1102, and the liquid discharge baffle 1103 is driven by a baffle motor (not shown in the figure) to move between the first position, the third position and the first position. In other embodiments, the liquid discharge baffle 1103 can also be in the form of a sliding baffle or the like. The baffle motor is electrically connected to the control system of the cleaning device 100, so as to control the motor according to the operating conditions of the cleaning device 100.

[0161] Please refer to FIG. 34 and FIG. 35, FIG. 34 is a schematic cross-sectional view of the tenth embodiment of the cleaning device of the present disclosure; FIG. 35 is a schematic cross-sectional view of the eleventh embodiment of the cleaning device of the present disclosure. In combination with FIG. 29 to FIG. 33, in other embodiments, the first sub-drainage port 1111 and the second sub-drainage port 1112 are both arranged in a direction substantially parallel to the center plane a; or, the first sub-drainage port 1111 and the second sub-drainage port 1112 are both arranged in a direction inclined to the center plane a of the cleaning device 100 by an angle between 0 degree and 30 degrees. By arranging the first sub-drainage port 1111 and the second sub-drainage port 1112 in front of and behind each other and in a direction substantially parallel to the center plane a, the cleaning device 100 can press the target bottom wall 410 more uniformly, reducing the occurrence of head lifting and tail lifting, and thus improving the stability of the cleaning device 100.

[0162] The cleaning device further comprises a drainage baffle 1103. The drainage baffle 1103 can adjust the jet flow of the first sub-drainage port 1111 and the second sub-drainage port 1112, so that the cleaning device 100 can meet different working conditions. For example, when the cleaning device 100 is on the target bottom wall 410, the drainage baffle 1103 moves to the second sub-drainage pipe 1102, and the jet flow of the first sub-drainage port 1111 is greater than that of the second sub-drainage port 1112, so that the jet force at the first sub-drainage port 1111 is greater than that at the second sub-drainage port 1112. When the cleaning device 100 changes from running on a horizontal surface to running on a downhill surface, the cleaning device 100 can quickly adhere to the downhill surface, so that the cleaning device 100 runs more stably.

[0163] When the cleaning device 100 is on the target side wall 420, the drainage baffle 1103 moves to the first sub-drainage pipe 1101, and the jet flow of the first sub-drainage port 1111 is less than that of the second sub-drainage port 1112, so that the jet force at the first sub-drainage port 1111 is less than that at the second sub-drainage port 1112. When the cleaning device 100 runs on the target side wall 420, the running direction of the cleaning device 100 is more stable.

[0164] Thus, by partially opening or closing the first sub-drainage pipe 1101 and the second sub-drainage pipe 1102 through the drainage baffle 1103, the jet flow in the first sub-drainage pipe 1101 and the second sub-drainage pipe 1102 can be adjusted, and thus the stability of the cleaning device 100 under different working conditions can be realized.

[0165] In some embodiments, the cleaning device can include a first main water pump 1311 and a second main water pump 1312. The outlet of the first main water pump 1311 is connected to the first sub-drainage pipe 1101. The outlet of the second main water pump 1312 is connected to the second sub-drainage pipe 1102. The first main water pump 1311 and the second main water pump 1312 are both connected to the filtering mechanism 120. The first main water pump 1311 and the second main water pump 1312 are independently connected to the corresponding first sub-drainage pipe 1101 and second sub-drainage pipe 1102, respectively, forming two different jet channels. By adjusting the power of the first main water pump 1311 and the second main water pump 1312, the cleaning device 100 can meet different working conditions. In addition, in this embodiment, by adjusting only the operating power of the first main water pump 1311 and the second main water pump 1312, the control of the jet force can be realized, so that there is no need to set a drainage baffle.

[0166] When the cleaning device 100 is on the surface to be cleaned, and the power of the first main water pump 1311 and the second main water pump 1312 is the same, the jet flow of the first sub-drainage port 1111 and the second sub-drainage port 1112 is the same. At this time, the cleaning device 100 uniformly pressurizes the surface to be cleaned, reduces the occurrence of head and tail tilting, and thus improves the stability of the cleaning device 100.

[0167] When the cleaning device is on the target bottom wall 410, the power of the first main water pump 1311 is controlled to be greater than the power of the second main water pump 1312, and the jet flow of the first sub-drainage port 1111 is greater than the jet flow of the second sub-drainage port 1112, so that the jet force at the first sub-drainage port 1111 is greater than the jet force at the second sub-drainage port 1112. When the cleaning device 100 changes from horizontal surface operation to downhill surface operation, the cleaning device 100 can quickly adhere to the downhill surface, so that the cleaning device 100 walks more stably.

[0168] When the cleaning device 100 is on the target side wall 420, the power of the first main water pump 1311 is controlled to be less than the power of the second main water pump 1312, and the jet flow of the first sub-drainage port 1111 is less than the jet flow of the second sub-drainage port 1112, so that the jet force at the first sub-drainage port 1111 is less than the jet force at the second sub-drainage port 1112. When the cleaning device 100 walks on the target side wall 420, the running direction of the cleaning device 100 is more stable.

[0169] When the cleaning device 100 encounters a step or a wall while walking on the pool bottom and needs to climb the step or the wall, the first main water pump 1311 is controlled to reduce power to reduce the downward pressure on the front of the cleaning device 100, so that the cleaning device 100 can smoothly transition to a vertical posture by tilting the head. Subsequently, the first main water pump 1311 can be controlled to increase power to increase the downward pressure of the cleaning device 100 to provide stronger wall climbing capability. When the cleaning device 100 transitions from a vertical surface to a horizontal surface on the step, by controlling the first main water pump 1311 to increase the operating power, the discharge flow rate of the first sub discharge port 1111 is increased, so that the cleaning device 100 can transition from a vertical state to a horizontal state more quickly, thereby improving the operating efficiency.

[0170] Thus, by adjusting the operating power of the first main water pump 1311 and the second main water pump 1312 or closing at least one of the first main water pump 1311 and the second main water pump 1312, the jet flow rate in the first sub discharge pipe 1101 and the second sub discharge pipe 1102 is adjusted, thereby realizing the stability of the cleaning device 100 under different working conditions.

[0171] When the cleaning device 100 includes the first main water pump 1311 and the second main water pump 1312, the first main water pump 1311 and the second main water pump 1312 are arranged in close proximity. For example, the first main water pump 1311 and the second main water pump 1312 are arranged in close proximity in front and back or in close proximity in left and right along the cleaning device 100. Among them, the first main water pump 1311 and the second main water pump 1312 are arranged outside the filtering mechanism 120, and the first main water pump 1311 and the second main water pump 1312 are in communication with the filtering mechanism 120.

[0172] Alternatively, when the cleaning device 100 includes the first main water pump 1311 and the second main water pump 1312, the first main water pump 1311 and the second main water pump 1312 are arranged in close proximity. When the first main water pump 1311 and the second main water pump 1312 are arranged in close proximity, the first main water pump 1311 is arranged in the filtering mechanism 120, and the second main water pump 1312 is arranged outside the filtering mechanism 120. The first main water pump 1311 and the second main water pump 1312 are in communication with the filtering mechanism 120. When the first main water pump 1311 is arranged in the filtering mechanism 120, the main water pump inlet 132 of the first main water pump 1311 is arranged with a filter layer for filtering and reducing impurities in the filtering mechanism 120 from entering the first main water pump 1311.
