Description

Technical Field

[0001] At least one embodiment of this disclosure relates to a housing module and a cleaning device. Background Technology

[0002] With the rapid development of modern technology, the concept of smart homes has gradually gained popularity. Through networked integrated intelligent control and management, smart homes are increasingly able to realize a new "people-oriented" home living experience. Among these, a wide variety of smart home appliances are emerging, including cleaning devices for home cleaning such as window cleaning robots and sweeping robots. Many cleaning devices typically use adsorption devices that employ vacuum adsorption. This involves using centrifugal fans or vacuum pumps as vacuum generators to create localized negative pressure between the robot body and the surface to be cleaned. Under the pressure difference, the robot adheres to the surface, thus enabling surface cleaning, especially for non-horizontal surfaces. To improve the cleaning performance of various cleaning devices, designing a solution that can increase the movement speed of the cleaning device while ensuring cleaning effectiveness has become a key research direction for the continuous advancement of next-generation cleaning devices.

[0110] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0111] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as “upper,” “lower,” “left,” and “right” are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described objects changes.

[0112] The components or structures in the accompanying drawings are not drawn to scale. For clarity, the dimensions of the components or structures may be exaggerated or reduced, but this should not be used to limit the scope of this disclosure. To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of known functions and known components may be omitted.

[0113] The inventors of this disclosure have discovered that cleaning devices on the market (e.g., window cleaners, robotic vacuum cleaners, etc.) can be broadly divided into two categories. One type uses a dual-disc twisting motion combination mode, where one disc rotates relative to the surface to be cleaned, thus performing a wiping action, while the other disc remains stationary relative to the surface. Its slow rotation drives the wiping disc to rotate around it until the next cycle, at which point the stationary disc and the wiping disc switch roles, thus twisting and moving. The other type of window cleaner uses a dual-track motion combination mode, where a wiping cloth can be fixed around the track. During movement, the wiping cloth slides relative to the surface to be cleaned, thus wiping it. In the dual-disc torsional movement combination mode, the cleaning device moves slowly and achieves movement and cleaning during the continuous switching of the two discs, resulting in low cleaning efficiency. In the dual-track movement combination mode, cleaning is only carried out by a ring of wiping cloth fixed around the track, which is less efficient than the mode in which the rotating wiping disc comes into contact with the cleaning surface. It usually cannot thoroughly clean the cleaning surface, resulting in poor cleaning effect.

[0114] Embodiments of this disclosure provide a housing module and a cleaning device. The housing module includes a lower housing assembly, an upper housing assembly, a first module, and a second module. The lower housing assembly includes a lower housing body and a middle cover, with the middle cover mounted on the lower housing assembly. The upper housing assembly cooperates with the lower housing assembly to form a receiving cavity. The lower housing body includes a bottom and a side portion. The bottom includes opposing first and second sides, and the side portion is disposed around the bottom to form a cavity on the first side of the bottom. The first module is mounted on the second side of the bottom. The second module is mounted on the second side of the bottom and spaced apart from the first module. The first module is configured to rotate about a rotation axis, and the second module is configured to rotate about an axis perpendicular to the rotation axis, which extends in a direction from the first side to the second side.

[0115] The housing module and cleaning device provided in this disclosure can combine the cleaning effect of the cleaning device with the travel speed. It includes both a module that enables the cleaning device to travel quickly in a straight line and a module that can clean by rotation. While ensuring the moving speed of the cleaning device, it significantly improves the cleaning efficiency of the cleaning device, thereby giving the cleaning device good cleaning performance.

By cooperating with each other, the cleaning device 1 can move in a straight line and turn. At the same time, the first module 630 can perform cleaning by rotating. That is, while ensuring the moving speed of the cleaning device 1, the cleaning efficiency of the cleaning device 1 is significantly improved, thus giving the cleaning device 1 good cleaning performance.

[0121] Figure 3A This is a schematic diagram of the structure of the lower shell body provided in an embodiment of the present disclosure. Figure 3B This is a structural schematic diagram of the lower shell body from another perspective, provided as an embodiment of the present disclosure.

[0122] refer to Figure 2 , Figure 3A and Figure 3B The bottom 600 includes a first mounting portion 631 and a second mounting portion 641. The first mounting portion 631 is the portion of the bottom 600 corresponding to the first module 630, and the second mounting portion 641 is the portion of the bottom 600 corresponding to the second module 640. The side portion 610 has a mating surface 611 away from the bottom 600. The distance L1 between the first mounting portion 631 and the mating surface 611 is less than the distance L2 between the second mounting portion 641 and the mating surface 611, so that there is a height difference ΔL between the first mounting portion 631 and the second mounting portion 641.

[0123] For example, the first module 630 can be mounted on the first mounting portion 631 by fasteners, while simultaneously allowing the first module 630 to rotate relative to the cleaning device 1. For example, in some embodiments of this disclosure, the first mounting portion 631 may include a rotating connecting shaft on which the first module 630 can be centrally fixed and rotate with the rotating connecting shaft. The fasteners are bolts or other elements that can rotate and fix the first module 630 to the first mounting portion 631; this is not limited.

[0124] For example, the second module 640 can be connected to the second mounting part 641 by means of snap-fit ​​or plug-in, and can move simultaneously with the cleaning device. This disclosure does not limit the connection method of the second module 640 and the second mounting part 641.

[0125] refer to Figure 2 , Figure 1C , Figure 3A and Figure 3B The mating surface 611 is located on the side of the side portion 610 away from the bottom 600. The mating surface 611 can be mated with the upper shell body 30 in the upper shell assembly 900, so that the mating surface 690 in the upper shell body 30 coincides with the mating surface 611, thereby providing cover and protection for the components in the cleaning device 1.

[0126] For example, when the distance L1 between the first mounting part 631 and the mating surface 611 is less than the distance L2 between the second mounting part 641 and the mating surface 611, and there is a height difference ΔL between the first mounting part 631 and the second mounting part 641, the second mounting part 641 is closer to the surface to be cleaned than the first mounting part 631, thus relatively reducing the exposed height Z of the second module 640. Furthermore, when a cleaning component, such as a cleaning cloth, is provided on the second module 640, the cleaning cloth can wrap around the second module 640, further reducing the exposed portion of the second module 640 and making the bottom of the cleaning device 1 more aesthetically pleasing.

[0127] refer to Figure 1A , Figure 2 and Figure 3A The lower housing assembly 10 also includes a cover portion 12. The second module 640 includes a cleaning frame 642 and a walking component 296. The bottom 600 includes a first opening 606 for mounting the walking component 296 and the cover portion 12. The cover portion 12 is mounted on the bottom 600 and configured to accommodate a portion of the walking component 296. The cleaning frame 642 has a second opening 607 to avoid the walking component 296 and to allow the walking component 296 to contact the surface to be cleaned, thereby enabling the cleaning device 1 to move on the surface to be cleaned.

[0128] For example, the housing portion 12 can be fixed to the first side 601 of the bottom 600 by fasteners, bolts, or other means of fixing, without limitation. For example, the housing portion 12 can accommodate a portion of the traveling member 296 and a drive member 297 of the traveling member 296. A portion of the traveling member 296 is disposed on the first side 601 of the bottom 600, and another portion extends through a first opening 606 to the second side 602 of the bottom 600. The drive member 297 is disposed on the first side 601 of the bottom 600, adjacent to the traveling member 296, and is configured to drive the traveling member 296 to move the cleaning device 1 along the traveling direction.

[0129] For example, the opening area of ​​the second opening 607 on the cleaning rack 642 is larger than the opening area of ​​the first opening 606 on the bottom 600. The second opening 607 can provide clearance for the traveling component 296 so that the traveling component 296 can rotate on the surface to be cleaned; the second opening 607 can also provide an air intake for the cleaning device 1 so that airflow can be drawn in from the bottom of the cleaning device 1 through the second opening 607.

[0130] Figure 4 for Figure 2 A partially enlarged schematic diagram of the second module in the cleaning device. (Reference) Figure 2 , Figure 3B and Figure 4The second module 640 includes a cleaning rack 642, which has double-layer ribs 648 and a bottom 600 with double-layer ribs 647. The double-layer ribs 648 on the cleaning rack 642 are all annular and form grooves 650 therebetween. The double-layer ribs 647 on the bottom 600 are all annular and form grooves 649 therebetween. The double-layer ribs 648 on the cleaning rack 642 and the double-layer ribs 647 on the bottom 600 are interlocked.

[0131] For example, the cleaning frame 642 and the bottom 600 are connected by double-layer ribs 648 and 647 through an interlocking method. This prevents the cleaning frame 642 from moving relative to the bottom 600 in a direction perpendicular to direction N, which would cause the cleaning frame 642 to shake and affect the control effect of the cleaning device. Direction N is the extension direction of the ribs in the double-layer ribs 647 or 648.

[0132] The number of ribs that interlock on the cleaning rack 642 and the bottom 600 can be the same or different, and there is no limitation on this. Furthermore, this disclosure does not limit the number of ribs that interlock on the cleaning rack 642 and the bottom 600. There can be one rib on the cleaning rack 642 and two ribs on the bottom 600, and they can also interlock. For example, the cleaning rack 642 or the bottom 600 can include multiple ribs, thereby increasing the strength of the interlocking joint.

[0133] refer to Figure 2 and Figure 4 The bottom 600 of the lower shell assembly 10 has an extended guide portion 651 on the second side 602. The height of the extended guide portion 651 is M1, and the height of each of the double-layer ribs 647 is M2. The height M1 of the extended guide portion 651 is less than the height M2 of each of the double-layer ribs 647 on the bottom 600, so that there is a moving space 652 between the cleaning rack 642 and the bottom 600 and the cleaning rack 642 has a moving amount M3 in the height direction N. The double-layer ribs 647 on the bottom 600 and the double-layer ribs 648 on the cleaning rack 642 provide guidance for the movement of the cleaning rack 642 in the height direction. The height direction N is the extension direction of the double-layer ribs 647 or 648, and the height of each rib is the height in the height direction N.

[0134] For example, the cleaning rack 642 has a movement amount M3 in the height direction N, which can reduce the assembly error of the cleaning device 1 and the matching error between it and the surface to be cleaned. When the cleaning device 1 performs a cleaning operation, the first module 630 and the second module 640 must maintain the same height as the matching surface of the surface to be cleaned, that is, there should be no height difference between the two and the matching surface of the cleaning surface to ensure sufficient contact with the cleaning surface. Therefore, when there is an assembly error or part design error in the cleaning device 1, resulting in the first module 630 and the second module 640 being inconsistent in height with the matching surface of the surface to be cleaned, the cleaning rack 642 can move in the direction N within the movement space 652 via the double-layer ribs 648. The value of the movement amount M3 can be determined according to the actual design requirements and is not limited thereto.

[0135] refer to Figure 2 and Figure 4 The extended guide portion 651 in the lower shell assembly 10 is located outside the double-layer ribs 647 on the bottom 600. The double-layer ribs 648 on the cleaning rack 642 include ribs 6481 and ribs 6482. Ribs 6481 are located in the groove 649 between the double-layer ribs 647 on the bottom 600. Ribs 6482 in the double-layer ribs 648 on the cleaning rack 642 are located in the groove 653 formed by the extended guide portion 651 and the ribs 6472 near the extended guide portion 651 on the bottom 600.

[0136] The extension direction of the extended guide 651 is consistent with that of the double-layer rib 647 or double-layer rib 648, thereby providing guidance in the N direction for the cleaning rack 642 to move in the moving space 652 via the double-layer rib 648, preventing the cleaning rack 642 from moving in the direction perpendicular to the N direction, so as to improve the adsorption effect.

[0137] refer to Figure 2 and Figure 4 The bottom 600 is also provided with a sealing rib 654 on the second side 602. The sealing rib 654 is located inside the double-layer rib 647 on the bottom 600. The sealing rib 654 and the rib 6471 of the double-layer rib 647 on the bottom 600 that is close to the sealing rib 654 form an accommodating space to accommodate the sealing member 655. The height M1 of the extended guide portion 651 is less than the height M4 of the sealing rib 654. The height M5 of the sealing member 655 is greater than the height of either the double-layer rib 647 or the double-layer rib 648 and is greater than the height M4 of the sealing rib 654.

[0138] For example, refer to Figure 2 and Figure 4The seal 655 is configured to be compressible. The seal 655 prevents airflow drawn in from the second opening 607 from leaking out through the gap between the double-layer ribs 647 and 648, thus providing a seal and ensuring the adsorption strength of the cleaning device 1. Simultaneously, the height M5 of the seal 655 is greater than the height of either the double-layer ribs 647 or 648; that is, the height M5 of the seal 655 is greater than the height M2 of the double-layer rib 647, greater than the height M6 of the double-layer rib 648, and greater than the height M4 of the sealing rib 654. This ensures that the cleaning rack 642 has a movement amount M3 in the height direction N. Furthermore, the seal 655 provides a buffer when the cleaning rack 642 moves towards the bottom 600, preventing impact or wear between the cleaning rack 642 and the bottom 600, thus avoiding damage to the device. The seal 655 may be made of foam or any material that can be squeezed and sealed, and this disclosure makes no limitation thereto.

[0139] Figure 5A for Figure 1D The cleaning device in the image is shown in a cross-sectional view along BB. (Reference) Figure 1A , Figure 2 and Figure 5A The bottom 600 has a limiting post 656 on the second side 602, and the cleaning rack 642 has a limiting hole 657. The limiting post 656 and the limiting hole 657 cooperate to connect the cleaning rack 642 and the bottom 600 by fasteners. The lower shell assembly 10 also includes a middle cover 20, which is located on the first side 601 of the bottom 600 and installed on the bottom 600. An air cavity 658 is provided between the middle cover 20 and the bottom 600. The second mounting part 642 of the bottom 600 has an adsorption hole 659. The mating part of the limiting post 656 and the limiting hole 657 communicates with the air cavity 658 through the adsorption hole 659 so that the mating part of the limiting post 656 and the limiting hole 657 serves as a leak detection hole.

[0140] For example, a fastener can be installed on the limiting post 656, but there is no connection between the fastener and the limiting hole 657. Under the limiting action of the fastener, the cleaning rack 642 is secured to the bottom 600 and will not fall away from the bottom 600. Simultaneously, after the fastener is installed on the limiting post 656, the cleaning rack 642 can be displaced at the limiting hole 657, and the displacement stroke can be Y. For example, the displacement stroke Y can be the same as the movement amount M3 of the cleaning rack 642. The fastener can be a bolt, or any part that meets the above assembly requirements; there are no restrictions on this.

[0141] For example, the size of the fastener will satisfy the requirement that there is a certain gap after the limiting post 656 and the limiting hole 657 are fitted together, so that airflow can pass through the gap.

[0142] refer to Figure 1A and Figure 5A The lower housing assembly 10 also includes a fan 21 and an air outlet hood 22. The middle cover 20 has a recess 660 with an air inlet 204. The fan 21 is located between the air outlet hood 22 and the recess 660 of the middle cover 20. The air outlet hood 22 is sealed to the periphery of the recess 660 of the middle cover 20. The space between the lower housing body 100 and the middle cover 20 forms an air cavity 658.

[0143] For example, when the fan 21 is running, the gas entering from the air inlet 204 will be directly discharged from the air outlet 22 due to the sealing structure of the air outlet 22 and the recess 660 of the middle cover 20, so as to prevent gas leakage and ensure the adsorption effect.

[0144] For example, there is a fitting gap between the limiting post 656 and the limiting hole 657. When the cleaning device 1 moves to an area outside the cleaning area, such as when part of the cleaning device 1 separates from the surface to be cleaned, the gap between the limiting post 656 and the limiting hole 657 can serve as a leak detection hole to change the air pressure of the air cavity 658, so that the cleaning device 1 can perform corresponding control operations to prevent the cleaning device 1 from separating from the surface to be cleaned and to ensure that the cleaning is carried out in an orderly manner.

[0145] For example, at least one air leak detection hole can be directly set in other locations in the cleaning device 1, such as at the edge of the second module, so as to more easily detect the movement status of the cleaning device 1, thereby providing a more timely and sensitive prompt to the cleaning device 1.

[0146] refer to Figure 2 and Figure 5A The air cavity 658 includes a first sub-air cavity 661 corresponding to the first module 630, a second sub-air cavity 662 corresponding to the second module 640, a first electronic control valve 663, and a second electronic control valve 664. The first electronic control valve 663 is configured to control the opening area of ​​the first sub-air cavity 661; the second electronic control valve 664 is configured to control the opening area of ​​the second sub-air cavity 662. The first and second sub-air cavities can be arranged independently of each other or connected to each other.

[0147] References 1 and 2 Figure 5A The lower shell assembly 10 includes a negative pressure mechanism 05, which includes at least one air cavity 658, an air inlet hood 203, at least one fan 21, and an air outlet hood 22. The air outlet hood 22 includes at least two air outlet channels, namely air outlet channel 666 and air outlet channel 667.

[0148] refer to Figure 1AThe upper housing assembly 900 in the cleaning device 1 includes an air outlet 372 and an air outlet 374. The air outlet shroud 22 includes a guide end 262 and a guide end 264, which are located above the surface 267 of the contour portion 26 of the middle cover 20 near the upper housing assembly 900. The guide end 262 communicates with the air outlet 372, and the guide end 264 communicates with the air outlet 374, thereby directing airflow through the air outlet shroud 22 and out through the air outlets 372 and 374 of the upper housing assembly 900. Sealing elements are provided at the connection points between the guide end 262 and the air outlet 372, and between the guide end 264 and the air outlet 374, to prevent airflow from flowing back into the air chamber 658.

[0149] Figure 5B This is a schematic diagram of the airflow path of a cleaning device provided in one embodiment of the present disclosure. (See reference) Figure 1A and Figure 5B The main airflow path in the cleaning device 1 may include: the fan 21 is running, and the airflow enters the fan 21 from the bottom of the cleaning device 1 through the air inlet 204 of the air inlet hood 203; the fan 21 includes multiple airflow holes 215, and the airflow entering the air inlet hood 203 flows through the fan 21 to the air outlet hood 22 in a direction away from the lower shell assembly 10 of the cleaning device 1; finally, the airflow can flow out from the guide end 262 and guide end 264 on the air outlet hood 22, and is discharged from the cleaning device 1 through the air outlet 372 and air outlet 374, ultimately forming a sealed chamber between the cleaning device 1 and the surface to be cleaned.

[0150] refer to Figure 2 and Figure 5A The first electronic control valve 663 is located at the air inlet channel of the first sub-air chamber 661, and the second electronic control valve 664 is located at the air inlet channel of the second sub-air chamber 662. For example, the first electronic control valve 663 and the second electronic control valve 664 can be controlled separately, that is, they can be selectively opened and closed, and controlled synchronously or asynchronously. By setting the first electronic control valve 663 and the second electronic control valve 664, the opening size of the first sub-air chamber 661 corresponding to the first module 630 and the opening size of the second sub-air chamber 662 corresponding to the second module 640 can also be adjusted, thereby adjusting the air intake volume so that the pressure between the first module 630 and the second module 640 and the surface to be cleaned is different, which facilitates better control of the movement of the cleaning device 1.

[0151] For example, in some embodiments, the negative pressure mechanism 05 may also be a combination of dual fans, a single air chamber and dual air outlet channels, or dual fans, dual air chambers and dual air outlet channels. This disclosure does not limit the number and design of the air chamber 658, the air inlet hood 203, the fan 21 and the air outlet hood 22.

[0152] This cleaning device 1 is suitable for surface cleaning in various situations. For example, when cleaning horizontal surfaces such as floors, tabletops, and carpets, the negative pressure mechanism 05 increases the pressure between the cleaning device 1 and the horizontal surface, increasing friction and improving cleaning effectiveness. When cleaning non-horizontal surfaces such as glass, walls, and cabinets, the negative pressure mechanism 05 allows the cleaning device 1 to adhere to the non-horizontal surface. In some examples, the cleaning device is a window cleaning robot, and the surfaces to be cleaned include windows or walls. For example, the windows can be framed or frameless. For example, framed windows can be residential windows, and frameless windows can be large floor-to-ceiling windows, etc.

[0153] Figure 6 A partial cross-sectional view of the connection between the auxiliary control board and the middle cover, provided in one embodiment of this disclosure. (See reference...) Figure 1A , Figure 5A and Figure 6 A pressure sensor 540 is installed inside the air cavity 658, and the pressure sensor 540 is configured to detect the air pressure inside the air cavity 658.

[0154] Figure 7 for Figure 1D A partial structural diagram of the second module in the cleaning device. (Reference) Figure 1A , Figure 2 and Figure 7 Wiper strips, namely wiper strips 670 and 671, are provided at both the front and rear of the traveling component 296 in the traveling direction. For example, when the second module 640 in the cleaning device 1 moves with the traveling component 296, the wiper strips 670 and 671 can remove dirt, such as water, from the traveling component 296 in the traveling direction, preventing the traveling component 296 from slipping when there is too much water, thus affecting the adsorption effect of the cleaning device 1. For example, when the cleaning device 1 is a window cleaning machine, the wiper strips 670 and 671 can prevent the window cleaning machine from slipping and falling.

[0155] refer to Figure 2 and Figure 7The traveling component 296 includes at least one roller 673, and a cleaning part 672 is provided on at least one side of the roller 673 to clean dirt from the roller. For example, the traveling component 296 may also include one or more rollers to meet different product design requirements. By providing the cleaning part 672, the traveling component 296 can be cleaned, ensuring that the traveling component 296 moves smoothly and normally in the direction of travel without jamming. There may be two cleaning parts 672, and the cleaning parts 672 may be located at opposite ends of the traveling component 296 in the direction of travel, or they may be located according to actual design requirements. This disclosure does not limit the location of the cleaning parts 672. The cleaning part 672 may be a cleaning brush; or, the cleaning part 672 may be any other component capable of cleaning the traveling component 296. This disclosure does not limit this.

[0156] For example, in some embodiments of this disclosure, the walking component 296 may be a track wheel assembly, and the cleaning unit 672 may be configured to clean impurities on the tracks and track wheels. For example, when the walking component 296 is a track wheel assembly, the number of track wheel assemblies is not limited to one; that is, it can be increased to multiple assemblies according to design requirements to increase the cleaning area and cleaning power of the cleaning device.

[0157] refer to Figure 2 and Figure 7 The cleaning rack 642 is provided with at least one sub-adsorption area 675, wherein each sub-adsorption area 675 includes at least one sub-adsorption hole 676, the at least one sub-adsorption hole 676 is arranged at intervals, and the cross-section of each sub-adsorption hole 676 is smaller than the opening cross-section of the second opening 607. There are two sub-adsorption areas 675, and the two sub-adsorption areas 675 are arranged on both sides of the second opening 607.

[0158] refer to Figure 1A , Figure 2 , Figure 5A and Figure 7Under the action of the negative pressure mechanism 05, airflow can enter the cleaning rack 642 near the fan 21 through the second opening 607, and then enter the air cavity 658 through the adsorption hole 659 of the second mounting part 641. Simultaneously, airflow can also enter the cleaning rack 642 near the fan 21 through the sub-adsorption area 675 and the sub-adsorption hole 676, and then enter the air cavity 658. For example, the opening area of ​​the second opening 607 can serve as the main adsorption area of ​​the cleaning device 1. The design combining the main adsorption area and the sub-adsorption area increases the area of ​​the negative pressure cavity in the cleaning device 1, improves the adsorption effect, and also ensures the strength of the cleaning rack. For example, when there is only one sub-adsorption hole 676, it is easier to manufacture and can reduce costs; when there are multiple sub-adsorption holes 676, it can ensure an increased air intake of the cleaning rack 642, thereby ensuring the strength of the cleaning rack during adsorption and reducing damage and deformation. This disclosure does not limit the number of sub-adsorption holes 676.

[0159] For example, in some embodiments of this disclosure, the number and positional relationship of the first module 630 and the second module 640 in the cleaning device 1 may include a variety of factors. Figure 8A This is a schematic diagram of a first module and a second module provided in an embodiment of the present disclosure. Figure 8B This is a schematic diagram of another first module and a second module provided in an embodiment of the present disclosure. Figure 8C A schematic diagram of another first module and a second module provided as an embodiment of this disclosure. (See reference...) Figure 2 and Figure 8A The first module 630 and the second module 640 are arranged side by side, and the rotation axis 678 of the first module 630 is within the first symmetry plane 679 of the second module 640. The first symmetry plane 679 is a plane that passes through the center of the second module 640 in a straight line direction perpendicular to the second module 640. The second module 640 is structurally symmetrical with respect to the first symmetry plane 679. Figure 2 The relative positional relationship between the first module 630 and the second module 640 in the middle and Figure 8A Same. For example... Figure 8A As shown, the first module 6308 and the second module 6408 are arranged side by side. The first module 6308 can rotate in the direction Y or the opposite direction of the direction Y, and the second module 6408 can travel in a straight line in the direction X or the opposite direction of the direction X.

[0160] For example, the first module 6308, under the action of the driving element (for example, the driving element can be connected with...), Figure 1AWhen the drive motor 14 shown rotates in the Y direction, the force corresponding to the first module 6308 is F4; conversely, the force corresponding to the first module 6308 is F3. For example, when the second module 6408 moves in the X direction, the driving force applied to it is F1, and conversely, the driving force applied to it is F2.

[0161] For example, one of the first module 6308 and the second module 6408 can be used as a drive wheel assembly. When the first module 6308 is used as the drive wheel assembly, and the driving force on the first module 6308 can be kept constant, the magnitude of the driving force F1 or driving force F2 on the second module 6408 can be adjusted to coordinate the movement of the second module 6408 with the first module 6308, enabling the cleaning device to move forward, backward, and turn. Similarly, the second module 6408 can also be used as the drive wheel assembly, and the driving force on the second module 6408 can be kept constant. The movement state of the cleaning device can be controlled by adjusting the magnitude of the driving force on the first module 6308.

[0162] For example, refer to Figure 2 In some embodiments of this disclosure, the lower shell assembly 10 may include a plurality of first modules 630 and a plurality of second modules 640, wherein the plurality of first modules 630 are spaced apart, the plurality of second modules 640 are arranged side by side and spaced apart, and the rotation center line of each first module does not overlap with the linear motion direction of each second module.

[0163] like Figure 8B As shown, the cleaning device may include a first module 6318 and a second module 6418, which are arranged side by side with a gap between them. The rotation center line L2 of the first module 6318 does not overlap with the linear motion direction L1 of the second module 6418, so as to ensure that the first module 6318 can move in coordination with the second module 6418.

[0164] Furthermore, the cleaning device can also have multiple first and second modules. For example... Figure 8C As shown, the lower shell assembly may include a first module 6328, a first module 6338, a second module 6428, a second module 6438, and a second module 6448. The first modules 6328 and 6338 are arranged side-by-side with intervals, as are the second modules 6428, 6438, and 6448. The rotation center line of each first module does not overlap with the linear motion direction of each second module. For example, the first modules 6328 and 6338 may also be arranged in a non-side-by-side configuration. By changing the number and relative position of at least one first module and at least one second module, the design of the actual product can be made more diverse, further improving the overall performance of the cleaning device.

[0165] Figure 10A This is a schematic diagram of the structure of an upper shell body provided for an embodiment of this disclosure. For example... Figure 1A As shown, the lower shell assembly 10 also includes a cover portion 12, and the cover portion 12 has a protrusion 120; the lower shell assembly 10, the middle cover 20, and the upper shell assembly 900 are arranged sequentially, with the protrusion 120 protruding towards the upper shell assembly 900; the middle cover 20 has a clearance portion 26 relative to the protrusion 120; the upper shell assembly 900 has a mating portion 38, and the mating portion 38 and the clearance portion 26 are arranged opposite to each other and cooperate to form a clearance structure relative to the protrusion 120. The upper shell body 30 and the middle cover 20 are detachably fixed, and the upper shell body 30 and the lower shell body 100 are mated and detachably fixed.

[0166] refer to Figure 1A and Figure 10A This corresponds to the clearance portion 26 of the middle cover 20. For example, the docking portion 38 is arranged opposite to the clearance portion 26 to facilitate the cooperation between the docking portion 38 and the clearance portion 26, thereby forming a clearance structure. For example, the clearance structure includes at least a clearance portion and a docking portion.

[0167] Without a clearance structure, clearance heights are required between the protrusion 120 and the middle cover 20, and between the middle cover 20 and the upper shell body 30, resulting in a relatively large height at the protrusion 120. However, with a clearance structure, only clearance height between the protrusion 120 and the upper shell body 30 is required. Therefore, by providing a clearance structure, the height and volume of the shell module at the protrusion 120 can be reduced. The reduced height includes at least the thickness of the middle cover 20, and clearance height between the protrusion 120 and the middle cover 20, and between the middle cover 20 and the upper shell body 30.

[0168] Therefore, by setting up an air-proof structure, the height and volume of the cleaning device can be reduced, as well as the weight of the housing module, making it easier to store and carry, and more aesthetically pleasing. When the weight of the cleaning device is reduced, the risk of the cleaning device falling off during the adsorption process is reduced, resulting in good cleaning performance.

[0169] For example, the docking portion 38 may be part of the upper shell body 30. In some embodiments, the docking portion 38 includes a rib provided on the upper shell body 30 and a portion of the upper shell body 30 surrounded by the rib. Of course, the docking portion 38 may also exclude the rib and only include a portion of the upper shell body 30.

[0170] In embodiments of this disclosure, the clearance portion 26 includes clearance holes 27 and 28, and at least a portion of the protrusion 120 protrudes from the clearance portion 27 and clearance holes 28.

[0171] like Figure 1AAs shown, since the protrusion 120 has the most significant impact on the overall height of the lower shell assembly 10, the arrangement of the clearance hole 27 and clearance hole 28 can make the two ends of the protrusion 120 in the lower shell assembly 10 as close as possible to the middle cover 20, until it can protrude out of the clearance hole 27 and clearance hole 28, thereby reducing the assembly gap between the lower shell assembly 10 and the middle cover 20.

[0172] refer to Figure 1A and Figure 10A As shown, the upper shell body 30 is assembled on the lower shell assembly 10, and the upper shell body 30 has multiple mating structures with the middle cover 20 inside.

[0173] like Figure 1A As shown, the lower housing assembly 10, the middle cover 20, and the assembly 900 of the cleaning device 1 are arranged sequentially. For example, as... Figure 1A As shown, the middle cover 20 is fixed to the lower shell assembly 10, and the upper shell body 30 is fixed to the lower shell assembly 10. The upper shell body 30 and the lower shell body 100 cooperate to form a cavity 103 (see...). Figure 17 ).

[0174] For example, the lower housing assembly 10, the middle cover 20, and the upper housing body 30 of the cleaning device 1 can be made of plastic or any material that can provide strong support, without any limitation.

[0175] Figure 10B This is a partial structural diagram of an upper shell body provided for an embodiment of the present disclosure. Figure 10C This is a partial structural diagram of an upper shell body provided for an embodiment of the present disclosure. Figure 10D This is a partial structural diagram of an upper shell body provided for an embodiment of the present disclosure. Figure 11A This is a schematic diagram of the structure of a lower shell assembly provided in one embodiment of the present disclosure. Figure 11B A top view of a casing portion is provided in one embodiment of this disclosure. Figure 11C A side view of a housing portion provided for an embodiment of this disclosure.

[0176] For example, refer to Figure 1A , Figure 11A , Figure 11B and Figure 11C In the housing module 01, the protrusion 120 of the lower housing assembly 10 has a cavity 29 on the side opposite to the upper housing body 30. The structure and internal volume of the cavity 29 are defined by the cover portion 12. For example, a walking component 296 and a driving component 297 of the cleaning device can be provided in the cavity 29. The driving component 297 is configured to drive the walking component 296 to rotate, thereby causing the driving component 297 to drive the cleaning device 1 to move.

[0177] like Figure 11BAs shown, the housing 12 comprises three parts: a first housing 291, a second housing 292, and a third housing 293. The first housing 291 and the second housing 292 are joined together as a single unit and are respectively fixedly connected to the lower housing body 100. The first housing 291 is connected to the lower housing body 100 via a first connecting part 2941 and a second connecting part 2942; the second housing 292 is connected to the lower housing body 100 via a third connecting part 2943 and a fourth connecting part 2944. For example, the first housing 291 and the second housing 292 can be fixedly connected to the lower housing body 100 by bolts, or by any other suitable means of achieving a fixed connection, which is not limited in this disclosure.

[0178] refer to Figure 1A , Figure 11A , Figure 11B and Figure 11C The walking component 296 in the cleaning device is disposed within a cavity 29 on the side of the protrusion 120 of the lower housing assembly 10 opposite to the upper housing body 30, and the cavity 29 is defined by a portion of the first cover 291 and the second cover 292. The driving component 297 is disposed on the side of the lower housing 10 near the upper housing body 30, and the space in the protrusion 120 accommodating the driving component 297 is defined by another portion of the second cover 292 and the third cover 293. Figure 11C As shown, the second cover 292 and the third cover 293 are fixedly connected by the first fixing part 2951, the second fixing part 2952, the third fixing part 2953 and the fourth fixing part 2954 respectively. For example, bolt connection or any other suitable method to achieve fixed connection can be used, and this disclosure does not limit this.

[0179] refer to Figure 1A , Figure 11B as well as Figure 11C In the lower shell assembly 10, the protrusion 120 defined by the cover portion 12 has the greatest impact on the overall height of the lower shell assembly 10. Since the middle cover 20 is disposed on the lower shell assembly 10, the middle cover 20 needs to be provided with a corresponding clearance structure for the protrusion in the lower shell assembly 10 to ensure the necessary assembly clearance.

[0180] Figure 12 This is a partial structural schematic diagram of a cover provided for an embodiment of the present disclosure. Figure 13 This is a schematic diagram of a lower shell assembly and a middle cover according to an embodiment of the present disclosure. In the embodiment of the present disclosure, the clearance portion 26 includes clearance holes 27 and 28. Figure 1A The example described uses a clearance section 26 comprising two clearance holes. In other embodiments, the clearance section may include one or more clearance holes. (See reference...) Figure 1A , Figure 12 and Figure 13At least a portion of the protrusion 120 in the housing module 01 protrudes from the clearance holes 27 and 28. The clearance portion 26 of the middle cover 20 also includes a contour portion 270 and a contour portion 280, with the contour portion 270 configured to define the clearance hole 27 and the contour portion 280 configured to define the clearance hole 28. By providing the clearance portion 26 to the middle cover 20, structural avoidance of the protrusion 120 of the lower housing assembly 10 can be cleverly achieved, reducing the structural complexity of the middle cover 20 by reducing the conformal design based on the protrusion 120. For example, in at least one embodiment of this disclosure, the design scheme of providing clearance holes for the protrusion 120 allows the middle cover 20 to reduce its overall height by using the clearance portion 26 relative to the protrusion 120. This not only reduces the weight of the middle cover 20 but also makes the body of the cleaning device 1 thinner and lighter overall. Furthermore, when the adsorption capacity of the cleaning device 1 is constant, the risk of the cleaning device 1 falling during operation can be reduced.

[0181] refer to Figure 1A and Figure 10A The upper shell body 30 of the cleaning device 1 is disposed on the lower shell assembly 10, and the interior of the upper shell body 30 includes multiple structures that are fixed or cooperate with the lower shell assembly 10 and the middle cover 20. For the clearance portion 26 of the middle cover 20, the docking portion 38 of the upper shell body 30 may include a structural form.

[0182] For example, the clearance portion 26 and the docking portion 38 are the same size and shape, making them easy to dock and fit together. Alternatively, the clearance portion 26 and the docking portion 38 can be nested together.

[0183] For example, refer to Figure 1A and Figure 10A The mating portion 38 of the upper shell body 30 includes annular ribs 39 and 40, and the ribs 39 and 40 have the same shape as the outline portion 26 of the middle cover 20. For example, the rib 39 has the same shape as the outline portion 280, and the rib 40 has the same shape as the outline portion 270.

[0184] For example, refer to Figure 1A and Figure 10A The mating portion 38 of the upper shell body 30 includes annular ribs 39 and 40, and the ribs 39 and 40 may be the same size as the outline portion 26 of the middle cover 20. For example, the rib 39 is the same size as the outline portion 280, and the rib 40 is the same size as the outline portion 270.

[0185] For example, refer to Figure 1A , Figure 2 , Figure 10B and Figure 12The mating portions 38 of the upper shell body 30 are symmetrically distributed around the central plane 02. Similarly, the contour portions 270 and 280 in the corresponding middle cover 20 are also symmetrically distributed. When the upper shell body 30 and the middle cover 20 are positioned opposite each other and fitted together, the plane of symmetry for the contour portions 270 and 280 is the same central plane 02. The following explanation focuses on the alignment and fitting of the contour portion 270 in the middle cover 20 with the rib 40 on the upper shell body 30.

[0186] refer to Figure 1A , Figure 2 , Figure 10B and Figure 12 The rib 40 of the upper shell body 30 includes a mating surface 401, and the contour portion 270 of the middle cover 20 includes a contour surface 271. When the rib 40 of the upper shell body 30 mates with the clearance portion 26 of the middle cover 20, since the rib 40 and the contour portion 270 have the same shape and size, the mating surface 401 can coincide with the contour surface 271, thereby realizing the relative setting and cooperation of the rib 40 and the contour portion 270, and the clearance portion 26 is shielded by the mating portion 38 of the upper shell body 30, forming a clearance structure relative to the protrusion 120. For example, see reference. Figure 10A and Figure 10B The rib 40 of the mating portion 38 of the upper shell body 30 can be provided with a certain depth L6, so that the rib 40 can define a cavity 402. Therefore, when the rib 40 is positioned opposite and engaged with the contour portion 270, the portion of the protrusion 120 on the lower shell assembly 10 that protrudes beyond the contour portion 270 can be further defined and concealed in the cavity 402 by the rib 40. That is, the cavity 402 can further provide concealing space for the portion of the protrusion 120 that protrudes beyond the contour portion 270. For example, in some embodiments of this disclosure, the depth L6 of the rib 40 can be non-uniform, so that the rib 40 can be easily positioned opposite and engaged with the contour portion 270.

[0187] For example, in at least one embodiment provided in this disclosure, the rib of the mating portion 38 of the middle cover 30 of the housing module 01 may be different in size from the outline portion 26 of the middle cover 20, so that the mating portion 38 and the clearance portion 26 are nested together.

[0188] refer to Figure 1A , Figure 10A , Figure 10B , Figure 10C , Figure 10D and Figure 12 The dimensions of the rib 40 in the mating portion 38 of the upper shell body 30 may differ from the outline portion 270 of the middle cover 20. For example, the rib 40 includes a side 403 and a side 404, with the side 403 located on the side away from the recess 402 and the side 404 located on the side close to the recess 402.

[0189] For example, the opening defined by the intersection of side surface 403 and mating surface 401 is called opening 405, and opening 405 is a parallelogram. For example, if the assembly gap between mating part 38 and contour part 26 is M, then when the size L7 of opening 405 is less than L3, the size L8 is less than L4, and L3-L7=2M, L4-L8=2M, the rib 40 of mating part 38 of upper shell body 30 can be inserted into contour part 270 of middle cover 20 in an interlocking manner, and the insertion depth is determined by the depth L6 of rib 40. For example, when the depth of rib 40 is uneven, the depth to which rib 40 is inserted into contour part 270 is the minimum depth of rib 40.

[0190] For example, the opening defined by the intersection of side surface 404 and mating surface 401 is called opening 406, and opening 406 is a parallelogram. For example, the contour portion 270 has a certain height N relative to the middle cover 30, and the thickness is uniform and set to K. When the size L9 of opening 406 is greater than L3, the size L... 10 Greater than L4, and L9-L3=2K+2M, L 10 When -L4 = 2K + 2M, the contour portion 270 can be inserted into the rib position 40 of the upper shell body 30 in an interlocking manner, and the insertion depth is determined by the depth L6 of the rib position 40 or the height N of the contour portion 270. For example, when the depth L6 of the rib position 40 or the height N of the contour portion 270 is not uniform, the insertion depth is the minimum value of the depth L6 or the height N.

[0191] For example, in some embodiments provided in this disclosure, the contour portion in the housing module includes an annular flange. For example, one of the mating portion and the contour portion includes a flange, and the other of the mating portion and the contour portion includes a recess to allow the mating portion and the contour portion to interlock.

[0192] Figure 14 A schematic diagram of the external structure of a middle cover is provided for another embodiment of this disclosure. Figure 15 This is a schematic diagram of the internal structure of an upper shell body provided in an embodiment of the present disclosure. Figure 16 This is a partial schematic diagram of the interior of an upper shell body provided for an embodiment of the present disclosure.

[0193] refer to Figure 14 and Figure 15 The contour portions 570 and 580 include a plurality of annular flanges 50, each flange 50 being cylindrical and arranged sequentially at intervals along the contour portion 570. For example, the number and shape of the flanges 50 on the contour portion 570 or contour portion 580 can be determined according to the needs of actual engineering design, and this disclosure does not impose any limitations on this.

[0194] For example, in a housing module provided in at least one embodiment of this disclosure, one of the mating portion and the contour portion includes a flange, and the other of the mating portion and the contour portion includes a recess, so that the mating portion and the contour portion can be inserted into each other.

[0195] For example, such as Figure 15 As shown, the mating portions 58 of the upper shell body 35 are symmetrically distributed around the central plane 05, that is, the annular ribs 59 and ribs 60 are symmetrically distributed along the central plane 05. Below, the ribs 59 of the upper shell body 35 and the contour portion 570 on the middle cover (as shown) Figure 14 (As shown) Relative settings and related explanations.

[0196] refer to Figure 14 and Figure 16 On the rib 59, a plurality of recesses 51 are sequentially provided relative to a plurality of flanges 50 on the contour portion 570, so that when the rib 59 of the upper shell body 35 is positioned relative to and engaged with the contour portion 570, each flange 50 on the contour portion 570 can be inserted into the plurality of recesses 51 corresponding to the rib 59, thereby fixing the upper shell body 35 and the middle cover 25 when they are positioned relative to and engaged.

[0197] For example, in some embodiments provided in this disclosure, multiple flanges 50 may also be provided on the ribs 59, and multiple corresponding recesses 51 may be provided on the contour portion 570, so that when the ribs 59 of the upper shell body 35 and the contour portion 570 are relatively arranged and cooperate, each flange 50 on the ribs 59 can be inserted into the corresponding multiple recesses 51 in the contour portion 570, thereby fixing the upper shell body 35 and the middle cover 25 when they are relatively arranged and cooperate.

[0198] For example, refer to Figure 1A , Figure 10B and Figure 12 In the housing module, the surface of the contour portion 270 near the upper housing body 30 is called contour surface 271, and the surface of the contour portion 280 near the upper housing body 30 is called contour surface 281. Contour surfaces 271 and 281 are symmetrically distributed, and both contour surfaces 271 and 281 are planar. For example, taking the relative arrangement and cooperation between the rib 40 and the contour portion 270 as an example, the mating surface 401 of the rib 40 can coincide with the contour surface 271, allowing the rib 40 to completely cover and close the contour portion 270. Therefore, setting the contour surfaces 271 and 281 as planar structures facilitates the installation and matching of the rib 40 and the contour portion 270 in the upper housing body 30, and ensures good sealing between the mating surface 401 and the contour surface 271.

[0199] Of course, in some embodiments of this disclosure, each contour surface and the corresponding mating surface on the rib are set to be non-planar, that is, the mating and matching relationship between each contour surface and the corresponding mating surface can be satisfied. The embodiments of this disclosure do not limit this.

[0200] As can be seen from the above embodiments, when the shape and size of the clearance portion 26 of the middle cover 20 and the docking portion 38 of the upper shell body 30 are the same, the clearance portion 26 and the docking portion 38 are fitted together by surface overlap; when the shape of the clearance portion 26 of the middle cover 20 and the docking portion 38 of the upper shell body 30 are the same but the size is different, the clearance portion 26 and the docking portion 38 are fitted together by a plug-in type; when the shape and size of the clearance portion 56 of the middle cover 25 and the docking portion 58 of the upper shell body 35 are the same, the clearance portion 56 and the docking portion 58 can be fitted together by docking.

[0201] For example, in some other embodiments of this disclosure, when the shape and size of the clearance portion 56 of the middle cover 25 and the docking portion 58 of the upper shell body 35 are different, the clearance portion 56 and the docking portion 58 can also be docked together, so that multiple recesses 51 can be inserted into multiple flanges 50. The number and arrangement position of multiple recesses 51 and multiple flanges 50 can be designed according to the cooperation structure of the clearance portion 56 and the docking portion 58, and this disclosure does not limit this.

[0202] For example, the housing module provided in at least one embodiment of this disclosure may further include a sealing element. For example, see reference to Figure 1A , Figure 10A and Figure 13 The cleaning device 1 also includes a sealing element 251 and a sealing element (not shown), and the sealing element 251 and the sealing element (not shown) are located between the mating portion 38 and the contour portion 26, and are configured to seal the mating portion 38 and the contour portion 26.

[0203] For example, refer to Figure 10B , Figure 12 and Figure 13 The sealing element 251 can be disposed on the contour surface 271 of the contour portion 270. When the rib 40 in the upper shell body 30 is disposed opposite to and engaged with the contour surface 271 through the mating surface 401, the sealing element can play a good sealing role during the pressing process, so as to ensure that the contour portion 270 and the rib 40 have good sealing performance after being disposed opposite to and engaged, and prevent airflow from flowing from the side of the middle cover 20 near the lower shell 10 to the side of the middle cover 20 away from the lower shell 10 after the contour portion 270 is covered by the rib 40.

[0204] For example, in some embodiments of this disclosure, the sealing element may also be disposed on the mating surface of each rib, that is, the sealing element 251 may also be disposed on the rib 40 and the rib 39, so that each sealing element plays a sealing role when the contour portion 270 is disposed opposite to and engaged with the rib 40 or when the contour portion 280 is disposed opposite to and engaged with the rib 39.

[0205] For example, refer to Figure 14 and Figure 15 When multiple flanges are provided on the contour portions 570 and 580, and corresponding multiple recesses are provided on the rib positions 59 and 60, each sealing element can simply make an opening at the position of each flange or rib to avoid them. This disclosure does not limit the shape of the sealing elements. Each sealing element may include foam or rubber rings, as well as any other sealing elements that can perform a sealing function. The embodiments of this disclosure do not limit this.

[0206] For example, refer to Figure 1A and Figure 13 The protrusion 120 of the lower shell assembly 10 includes a first protruding end 1204 and a second protruding end 1205. Two clearance portions are provided, and these two clearance portions are configured to respectively clear the first protruding end 1204 and the second protruding end 1205, and are respectively located at the first protruding end 1204 and the second protruding end 1205. For example, the location of the clearance structure can be set according to the first protruding end 1204 and the second protruding end 1205 in the protrusion 120. For example, the first protruding end 1204 and the second protruding end 1205 can be set at positions where the matching structure of the protrusion 120 with the middle cover 30 is more demanding. For example, they can be set in the area where the height of the protrusion 120 relative to the lower shell 10 is the highest, so that when the middle cover 20 needs to make a conformal protrusion design for the protrusion 120, the arrangement of the clearance structure reduces the structural features of the middle cover 20 and lowers the height of the middle cover 20 and the upper shell body 30.

[0207] Figure 17 This is a cross-sectional view of a cleaning apparatus provided in one embodiment of the present disclosure. Figure 18 Another cross-sectional view of a cleaning apparatus provided according to an embodiment of this disclosure. (See also...) Figure 13 and Figure 17 When two clearance structures are provided according to the protrusion 120, the two clearance structures are symmetrically distributed with respect to a plane 06 between the two clearance structures. For example, when the two clearance structures are symmetrically arranged, it is beneficial to reduce the structural complexity of the middle cover 20 and the upper shell body 30, maintain the stability of the structure, and facilitate manufacturing and operation.

[0208] For example, refer to Figure 13 , Figure 17 and Figure 18The middle cover 20 has a connecting portion 275 located between two clearance holes in the two clearance structures. The connecting portion 275 includes a flat portion 276 near the upper shell body 30, and two contour portions in the two clearance structures, namely contour portion 270 and contour portion 280. Each contour portion is inclined relative to the flat portion 276, and the inclination angles between contour portion 270 and contour portion 280 and the flat portion 276 are the same. The inclination angle between contour portion 270 and flat portion 276 is α1, and the inclination angle between contour portion 280 and flat portion 276 is α2, and α1 and α2 are equal in magnitude.

[0209] For example, refer to Figure 1A , Figure 13 , Figure 17 and Figure 18 On the first protruding end 1204 and the second protruding end 1205, clearance portions 26 are provided on the middle cover 20, allowing the protruding portion of the first protruding end 1204 to be placed in the clearance hole 27 and the protruding portion of the second protruding end 1205 to be placed in the clearance hole 28. When the upper shell body 30 is engaged with the middle cover 20, recessed structures 305 and 306 close to the traveling component 296 can be provided on the clearance portions 26 corresponding to the middle cover 20. The recessed structures 305 and 306 of the upper shell body 30 allow the upper shell body 30 to be as close as possible to the middle cover 20 and the traveling component 296 while meeting the assembly clearance requirements, thereby reducing the distance between the upper shell body 30 and the traveling component 296 and lowering the overall height of the cleaning device 1, making it easier to store and carry.

[0210] Figure 19 This is a structural schematic diagram of the lower shell assembly and the middle cover in a shell module, provided for another embodiment of the present disclosure. Figure 20 for Figure 19 A cross-sectional view of the cleaning device provided. (Reference) Figure 19 and Figure 20The protrusion 120 of the lower shell assembly 10 includes a first protruding end 1201 and a second protruding end 1202. A clearance portion is provided, configured to provide clearance for the first and second protruding ends 1201 and extend from the first protruding end 1201 to the second protruding end 1202. At this time, a contour portion 290 and an opening 29 defined by the contour portion 290 are formed on the middle cover 20. The side of the protrusion 120 away from the lower shell 10 can protrude from the opening 29. Corresponding to the contour portion 290 on the middle cover 20, the upper shell body 30 is provided with a mating portion (not shown) that can be disposed opposite to and cooperate with the contour portion 290. This mating portion may include an annular rib 91, and a sealing element 291 is provided between the rib 91 and the contour portion 290 to enhance the airtightness between the middle cover 20 and the upper shell body 30. Regarding the relative arrangement and engagement between the rib 91 and the contour portion 290, and the arrangement of the sealing element 291, please refer to the methods in the above embodiments, which will not be repeated here.

[0211] For example, by providing a clearance structure 1203 for the protrusion 120, the clearance range for the protrusion 120 is further increased, and the assembly distance between the middle cover 20 and the lower shell 10 can be significantly reduced. Simultaneously, the upper shell body 30 can be structurally designed to be as close as possible to the protrusion 120 at the position corresponding to the protrusion 120. Therefore, this solution can further reduce the weight of the entire shell module and allow for a further reduction in the height of the cleaning device.

[0212] For example, refer to Figure 1A and Figure 17 In the housing module 01 provided in at least one embodiment of this disclosure, the middle cover 20 is located within the cavity 103 formed by the lower housing assembly 10 and the upper housing body 30. The middle cover 20 has a small volume, and its projection along the direction close to the lower housing 10 can completely fall into the lower housing 10. The upper housing body 30 includes multiple structures that cooperate with and are fixed to the middle cover 20 and the lower housing 10, and after the upper housing body 30 and the lower housing 10 are fixed, a cavity 103 can be formed. Multiple operating elements required by the cleaning device 1 can be arranged in the cavity 103. At the same time, the middle cover 20 is also arranged in the cavity 103 to facilitate the orderly arrangement of multiple operating elements at intervals, and to increase the strength and structural stability of the housing module 01 in the cleaning device 1.

[0213] refer to Figure 1A , Figure 11CThe walking component 296 is disposed on the side of the lower housing assembly 10 away from the upper housing body 30, wherein the side of the protrusion 120 opposite to the upper housing body 30 has a cavity 29, and at least a portion of the walking component 296 is located within the cavity 29. For example, the walking component 296 includes a track module, but is not limited thereto. In other embodiments, the walking component 296 may include a roller module, for example, the roller module includes two rollers, the rotation of which enables the cleaning device 1 to move in a straight line.

[0214] like Figure 17 As shown, during the airflow process, when the air-blocking part 26 is shielded by the docking part 38, the docking part 38 on the upper shell body 30 can seal the air-blocking part 26. Therefore, the airflow cannot leak into the air cavity 103 between the middle cover 20 and the upper shell body 30. As a result, the airflow in the main flow path will not be reduced, thereby ensuring the adsorption effect of the cleaning device 1 and reducing the risk of the cleaning device 1 falling during operation.

[0215] like Figure 21 , Figure 22 , Figure 23A As shown, the upper shell assembly 900 includes a decorative element 36 and an upper shell body 30. The upper shell body 30 is provided with an air outlet 910. The decorative element 36 is connected to the upper shell body 30. The air outlet 910 is located within the orthographic projection of the decorative element 36 onto the upper shell body 30, so that the air outlet 910 is located within the protective space 960 formed by the decorative element 36 and the upper shell body 30. Figure 23A As shown, the protective space 960 is formed by the decorative element 36 and the upper shell body 30 to protect the air outlet and prevent it from being blocked. Thus, the decorative element provides a certain degree of protection for the air outlet, preventing dust, sewage and other foreign objects from falling into the upper shell body through the air outlet, thus preventing blockage of the air outlet. At the same time, it facilitates the operation of the cleaning device and helps to extend the life of the cleaning device.

[0216] In some examples, such as Figure 22 and Figure 24 As shown, the upper shell body 30 has a protruding structure 901 protruding towards the decorative member 36. The protruding structure 901 forms a cavity 903 on the side away from the decorative member. An air outlet 910 is disposed in the sidewall 903a of the protruding structure 901 forming the cavity 903. The decorative member 36 and the upper shell body 30 cooperate to form an air outlet space 902 so that the air outlet 910 is not obstructed in the air outlet direction X. Therefore, within this air outlet space 902, the air outlet is protected by the decorative member, preventing dust, sewage, and other foreign objects from falling into the upper shell body through the air outlet; and the air outlet direction X is not obstructed, thus not affecting the air outlet performance. Figure 22 As shown, the air outlet space 902 is the area through which the air flows from the air outlet.

[0217] In some examples, such as Figure 23B As shown, in the air outlet space 902 formed by the decorative element 36 and the upper shell body 30, in the right view, the upper shell assembly 900 is located outside the air outlet 910. That is, both the decorative element 36 and the upper shell body 30 are configured to avoid the air outlet direction in order to form the air outlet space 902. Thus, the air outlet direction or air outlet position of the air outlet 910 is not blocked by the structure of the upper shell assembly 900.

[0218] For example, such as Figure 21 He Ru Figure 22 As shown, the protruding structure 901 is located within the orthographic projection of the decorative piece 36 onto the upper shell body 30. The decorative piece 36 protrudes from the air outlet 910 in the air outlet direction to protect the air outlet, and a notch 905 is provided on the side with the air outlet to avoid the air outlet direction. Figure 21 and Figure 22 As shown, the decorative piece 36 has a notch 905 in the air outlet 910 in the air outlet direction X to better avoid the air outlet's air outlet direction. Therefore, by setting the notch 905, the air outlet has a larger air outlet space. Figure 21 He Ru Figure 22 As shown, notch 905 refers to the part of the decorative piece 36 that is missing or removed near the air outlet.

[0219] For example, such as Figure 21 and Figure 22 As shown, the upper shell body 30 has an enclosure portion 904, and a protruding structure 901 protrudes towards the decorative member 36 relative to the enclosure portion 904. The portion of the enclosure portion 904 located on the side of the protruding structure 901 where the air outlet 910 is located is relatively lower than the air outlet; that is, the height of the portion of the enclosure portion 904 in the air outlet space 902 is lower than the height of the portion of the upper shell body 30 that forms the air outlet. Therefore, the structure of the enclosure portion on the air outlet side does not obstruct the air outlet direction, resulting in a better air outlet effect.

[0220] For example, such as Figure 21 and Figure 22 As shown, the decorative element 36 is provided with an extension 725, which connects the decorative element 36 to the upper housing body 30. The extension 725 near the air outlet 910 can be elongated. This allows for a wider air outlet space between the decorative element and the upper housing body, resulting in better airflow performance.

[0221] For example, the upper casing includes at least one air outlet 910. Figures 21 to 23B Taking the upper shell body 30 with two air outlets 910 as an example, the explanation is as follows. However, the number of air outlets 910 is not limited to two and can be set according to needs. In some examples, such as... Figure 22 and Figure 23A As shown, the upper shell body 30 is also provided with a wiring port 920. The wiring port 920 is disposed in the side wall 903a of the cavity 903 formed by the protruding structure 901, and the wiring port 920 is located within the orthographic projection of the decorative member 36 onto the upper shell body 30, so that the wiring port 920 is located within the protective space 960 formed by the decorative member 36 and the upper shell body 30. Thus, the wiring port can be disposed within the protective space formed by the decorative member and the upper shell body. In this air outlet space, the wiring port is protected by the decorative member, preventing dust, sewage and other foreign objects from falling into the upper shell body through the wiring port, thus protecting the wiring port and the wiring passing through the wiring port. At the same time, it facilitates the operation of the cleaning device and helps to extend the life of the cleaning device.

[0222] For example, the wiring port 920 is configured to allow wiring, such as power cables, to pass through it. Thus, the wiring, such as power cables, can enter the interior of the upper housing through the wiring port and connect to corresponding components such as circuit boards, batteries, drivers, etc., providing them with power. For example, the air vent and the wiring port can also be located on any side of the upper housing.

[0223] In some examples, such as Figure 22 and Figure 24 As shown, the upper shell body 30 has two air outlets 910. The two air outlets 910 and the wiring port 920 are all located on the same side of the cavity 903, and the two air outlets 910 are located on both sides of the wiring port 920. The air outlets 910 can be located on both sides of the wiring port 920, and are symmetrical about the wiring port 920.

[0224] Figure 25 for Figure 21 The top view of the upper shell body shown; Figure 26 for Figure 25 An exploded view of the upper shell body shown;

[0225] Figure 27 for Figure 26 A partially enlarged schematic diagram of the upper shell body is shown. (See attached image.) Figure 26 and Figure 27 As shown, the upper shell body 30 also includes a wiring channel 922. The wiring channel 922 is located on the side of the upper shell body 30 away from the decorative part 36. The wiring channel 922 has a first channel opening 922a and a second channel opening 922b, and the first channel opening 922a is arranged opposite to the wiring opening 920. Thus, after the wires enter the upper shell body through the wiring openings, they can be fixed in the wiring channel, which plays a role in fixing, supporting and protecting the wires, preventing the wires from shifting, and ensuring that the cleaning device can be used normally after being powered on.

[0226] In some examples, such as Figure 25 , Figure 26 and Figure 27As shown, an arc-shaped bend 921a is provided between the first channel opening 922a and the second channel opening 922b via the wiring channel 922. This arc-shaped bend provides better fixation, support, and protection for the wiring, preventing displacement and ensuring normal operation of the cleaning device after it is powered on. Multiple arc-shaped bends can be provided between the first channel opening 922a and the second channel opening 922b via the wiring channel 922.

[0227] In some examples, such as Figure 25 , Figure 26 and Figure 27 As shown, the upper housing assembly 900 also includes a wire clamping plate 923. The wiring channel 922 includes two wiring fixing parts 921. The two wiring fixing parts 921 and the wire clamping plate 923 form an "S-shaped" fixed wiring channel 922. The wire clamping plate 923 is connected to the upper housing body 30, and the orthographic projection of the wire clamping plate 923 onto the upper housing body 30 covers the wiring channel 922. Thus, the wire clamping plate secures the wires to the wiring channel, providing fixation, support, and protection for the wires, preventing wire displacement, and ensuring normal operation of the cleaning device after it is powered on.

[0228] like Figure 25 , Figure 26 and Figure 27 As shown, the wire clamping plate 923 is provided with an opening 923b, and the upper shell body 30 is provided with a mounting post 923c. Fasteners such as screws or bolts can be screwed onto the mounting post 923c through the opening 923b, thereby connecting the wire clamping plate to the upper shell body via fasteners. For example, there can be at least one pair of openings and corresponding mounting posts, and the number of them is not limited in this embodiment.

[0229] In some examples, such as Figure 26 and Figure 27 As shown, the wiring channel 922 is provided with a channel rib 922c. The channel rib 922c is located within the wiring channel 922, and the side of the channel rib 922c away from the upper shell body has a surface concave to the upper shell body. The axial direction of the surface of the channel rib 922c away from the upper shell body 30 points towards the first channel opening or the second channel opening. Therefore, the channel rib can fix and support the wiring passing through the wiring channel, preventing wire displacement and ensuring normal operation of the cleaning device after power-on. The surface of the channel rib away from the upper shell body can be adapted to the arc shape of the wiring passing through the wiring channel, thus providing better fixation and support for the wiring.

[0230] In some examples, such as Figure 26 and Figure 27As shown, the wire clamping plate 923 includes two wire clamping ribs 923a, which are located on both sides of the channel rib 922c in the orthographic projection of the upper shell body 30. Therefore, the two wire clamping ribs can be staggered with the channel rib, providing better fixation and support for the wires passing through the wiring channel.

[0231] For example, such as Figure 25 , Figure 26 and Figure 27 As shown, the upper housing body 30 is also provided with a wire-holding groove 925. After the wire passes through the wiring channel 922, it can be fixed by the wire-holding groove 925, which further fixes, supports and protects the wire, prevents the wire from shifting and ensures that the cleaning device can be used normally after being powered on. For example, there can be multiple wire-holding grooves, and the number is not limited in this embodiment.

[0232] In some examples, such as Figure 22 and Figure 23B As shown, the wiring port 920 also includes a wiring sleeve 924, which is nested within the wiring port 920. This provides further fixation, support, protection, and buffering for the wiring passing through the wiring port, preventing wire displacement, avoiding wear and tear on the wiring due to the edges of the wiring port, and preventing dust, sewage, and other foreign objects from falling into the upper housing through the wiring port. This ensures normal operation of the cleaning device after it is powered on, protecting the operation and lifespan of the cleaning device.

[0233] For example, the material of the cable sheath can be a soft material, such as rubber or silicone rubber. Of course, the material of the cable sheath is not limited to these, and the material of the cable sheath can also be other forms.

[0234] Figure 28 This is a schematic diagram of the structure of a wiring sheath in an upper shell assembly according to an embodiment of the present disclosure; Figure 29 for Figure 23B The diagram shows a cross-sectional view of the upper shell assembly along section line CB. (See diagram below.) Figure 28 and Figure 29 As shown, the outer ring of the cable sheath 924 includes a groove 924a, which is nested in the cable opening 920. Thus, the groove structure allows the cable sheath to be securely nested in the cable opening, preventing it from falling off due to cable movement.

[0235] In some examples, such as Figure 28 and Figure 29As shown, the groove 924a and the wiring opening 920 are configured with an interference fit along the radial direction of the wiring opening 920. This restricts the radial movement freedom of the wiring sleeve, allowing it to be more securely nested in the wiring opening. The decorative piece 36 and the wiring sleeve 924 are configured with an interference fit along the direction from the decorative piece 36 towards the wiring opening 920. Therefore, after the decorative piece is connected to the upper housing body, the interference fit between the decorative piece and the wiring sleeve can further press and fix the wiring sleeve, making it more securely nested in the wiring opening.

[0236] In some examples, such as Figure 22 and Figure 28 As shown, the decorative component 36 includes a first limiting rib 927, which is fitted or interference-fitted with the wiring sleeve 924 along the axial direction of the wiring opening 920. Thus, the first limiting rib can further compress and fix the wiring sleeve, making the wiring sleeve more securely nested in the wiring opening.

[0237] In some examples, Figure 30 for Figure 22 The diagram shows a partial structural schematic of the upper shell assembly. Figure 28 , Figure 29 and Figure 30 As shown, the upper shell body 30 includes a second limiting rib 926, and the cable routing sleeve 924 includes a limiting opening 924b. The second limiting rib 926 is embedded in the limiting opening 924b. Thus, the cable routing sleeve can be further compressed and fixed by the cooperation of the limiting opening and the second limiting rib, making the cable routing sleeve more securely nested on the cable routing opening.

[0238] Figure 9A This is a schematic diagram of the water outlet range of the nozzle and the air outlet range of the air outlet in a cleaning device provided as an embodiment of the present disclosure. Figure 9B This disclosure provides a schematic diagram of an air outlet according to one embodiment.

[0239] In some examples, such as Figure 9B As shown, the air outlet 910 includes a one-way section 911. The one-way section 911 is unidirectionally oriented along the air outlet's outlet direction; that is, when airflow exits the air outlet along the outlet's outlet direction, the one-way section opens; when airflow enters the air outlet against the outlet direction, the one-way section closes. By providing the one-way section, airflow can be restricted to exiting the air outlet only along the outlet direction. Simultaneously, the one-way section can also adjust the gas pressure inside the air chamber. For example, the one-way section can be a one-way valve or a one-way diaphragm; of course, the one-way section can also have other structural forms.

[0240] refer to Figure 1A , Figure 9A and Figure 9BThe water outlet area of ​​nozzle 31 is A1, and the air outlet range of air outlet 372 is A2. Because the air outlet 910 has a one-way section 911 inside, the airflow inside the cleaning device 1 is not disturbed by the external airflow near the air outlet 910, thus allowing it to flow in and out in an orderly manner in one direction. Furthermore, the water outlet area A1 and the air outlet range A2 do not overlap. Similarly, the air outlet range (not shown) of air outlet 374 also does not overlap with the water outlet area A1. Therefore, when the cleaning device 1 is operating, water sprayed from nozzle 31 can be prevented from entering the cleaning device 1 through air inlet 204.

[0241] In some examples, such as Figure 21 and Figure 22 As shown, the upper housing assembly 900 also includes a button 32, which is connected to the upper housing body 30. The air outlet 910 and the wiring port 920 are located on the side of the upper housing body 30 away from the button 32. Figure 21 and Figure 22 As shown, button 32 is located on the left side of the upper shell body 30, and air outlet 910 and wiring port 920 are located on the right side of the upper shell body 30. The air outlet 910 and wiring port 920 are set relatively far away from button 32.

[0242] One embodiment of this disclosure also provides a cleaning device. Figure 31 This is a schematic diagram of a cleaning device provided according to an embodiment of the present disclosure. Figure 31 As shown, the cleaning device 1 includes the aforementioned upper shell assembly 900. Therefore, the cleaning device has the same technical effects as the aforementioned upper shell assembly. For example, the air outlet of the cleaning device can be located within the protective space formed by the decorative element and the upper shell body. The decorative element protrudes from the air outlet along the air outlet direction and is configured to avoid the air outlet's air outlet direction. The air outlet's air outlet direction within this air outlet space is not obstructed, thus not affecting the air outlet effect. The air outlet is protected by the decorative element, preventing dust, sewage, and other foreign objects from falling into the upper shell body through the air outlet, thereby preventing blockage of the air outlet. This also facilitates the operation of the cleaning device and extends its lifespan.

[0243] Figure 32 for Figure 31 The disassembly diagram of the cleaning device is shown. Figure 31 and Figure 32As shown, the cleaning device 1 also includes a lower housing assembly 10 and a negative pressure mechanism 05. The negative pressure mechanism 05 includes an air inlet hood 203, a fan 21, and an air outlet hood 22. The upper housing assembly 900 is connected to the lower housing assembly 10, and the negative pressure mechanism 05 is also connected to the lower housing assembly 10. The fan 21 is located within the space enclosed by the air inlet hood 203 and the air outlet hood 22. The air inlet hood 203 and the air outlet hood 22 are sealed together. The air outlet hood 22 is provided with a guide channel 262a, which communicates with the air outlet 910. The guide channel 262a is located in the cavity 903. The negative pressure mechanism 05 is configured to draw airflow from the bottom of the lower housing assembly 10 through the air inlet hood 203 by operating the fan 21, and then discharge the airflow through the air outlet hood 22, the guide channel 262a, and the air outlet 910. Thus, the cleaning device can be adsorbed onto the surface to be cleaned by the negative pressure mechanism. After passing through the negative pressure mechanism, the airflow is discharged through the air outlet. Since the air outlet is not blocked in the air outlet space, the air outlet effect is not affected. In addition, the air outlet is protected by the decorative part in the direction of the decorative part pointing to the upper shell body, which prevents dust, sewage and other foreign objects from falling into the cleaning device through the air outlet, thereby avoiding clogging the air outlet and not affecting the operation of the negative pressure mechanism.

[0244] For example, such as Figure 24 and Figure 32 As shown, part of the air outlet hood 22 can be set inside the cavity 903, and the guide channel 262a on the air outlet hood 22 is sealed and connected to the air outlet 910 inside the cavity 903.

[0245] Figure 33 This is a schematic diagram of a decorative component provided in one embodiment of the present disclosure. Figure 34 for Figure 33 An exploded view of the decorative element shown. (As shown) Figure 33 and Figure 34 As shown, the decorative component 36 includes a decorative component body 720, a decorative component rib 721, and a water tank bottom shell 34. The decorative component rib 721 is located on the side of the decorative component body 720 near the water tank bottom shell 34. The water tank bottom shell 34 is connected to the decorative component rib 721 and is sealed to the decorative component rib 721. The water tank bottom shell 34, the decorative component rib 721, and the portion of the decorative component body 34 surrounded by the decorative component rib 721 form a water tank 701.

[0246] In the decorative component provided in this embodiment, the water tank can be formed by a water tank bottom shell, decorative component ribs, and a portion of the decorative component body surrounded by the decorative component ribs. The water tank and decorative component are integrated into a single design, eliminating the need for a separate water tank design, thus saving material quantity and cost, and improving the assembly efficiency of the cleaning device. The water tank can be used to store cleaning fluid. For example, the cleaning fluid can be water, detergent, etc.

[0247] In some examples, such as Figure 33 and Figure 34 As shown, the decorative rib 721 and the decorative body 720 are integrally formed. Therefore, except for the bottom shell, the rest of the water tank is integrally formed from the decorative part, increasing the degree of integration between the water tank and the decorative part, saving material quantity and cost, and improving the assembly efficiency of the cleaning device.

[0248] Figure 35 for Figure 34 The decorative element shown is a cross-sectional view along the section line RT. (See diagram below.) Figure 34 and Figure 35 As shown, a first snap-fit ​​part 712 is provided on one of the water tank bottom shell 34 and the decorative rib 721, and the other is fixed together by the first snap-fit ​​part 712.

[0249] For example, such as Figure 34 and Figure 35 As shown, the water tank bottom shell 34 is provided with a first snap-fit ​​portion 712, which is located on the side of the water tank bottom shell 34 near the decorative rib 721. The water tank bottom shell 34 is fixed to the decorative rib 721 by the first snap-fit ​​portion 712. The water tank bottom shell and the decorative rib are bonded or welded. For example, bonding can be done using UV adhesive, hot melt adhesive, structural adhesive, etc. For example, welding can be done using ultrasonic welding, high-frequency welding, infrared welding, laser welding, etc., to achieve a sealed connection between the water tank bottom shell and the decorative rib, preventing the liquid stored in the water tank from leaking out.

[0250] In some examples, such as Figure 33 , Figure 34 and Figure 35 As shown, the bottom shell 34 of the water tank is provided with a water outlet 711, and the bottom shell 34 is provided with a concave surface 713 that moves away from the decorative body 720, with the water outlet 711 located at the bottom of the concave surface 713. Thus, this concave surface can form a guide surface with the water outlet as the lowest point, preventing liquid residue in the water tank. For example, the bottom shell 34 of the water tank is provided with two water outlets 711, located on both sides of the bottom shell 34. Of course, the embodiments of this disclosure do not limit the number of water outlets 711. Figure 34 and Figure 35 As shown, the concave surface 713 is an inclined surface. For example, the concave surface 713 can also be an arc surface. Of course, embodiments of this disclosure include, but are not limited to, this, and the concave surface can also be in other forms.

[0251] For example, such as Figure 34 and Figure 35 As shown, the concave surface 713 is formed by making an inclined surface with the outlet 711 as the center, thus forming a centripetal inclined surface with the outlet 711 as the center. For example, the concave surface 713 can also be formed by making an arc surface with the outlet 711 as the center, thus forming a centripetal arc surface with the outlet 711 as the center. Figure 36 This is an exploded view of a decorative component according to an embodiment of the present disclosure. Figure 36 As shown, the decorative component 36 includes a water tank cover 35, and the decorative component body 720 is provided with a water inlet 722. The water inlet 722 is located in the part of the decorative component body 720 that constitutes the water tank 701. One end of the water tank cover 35 is sealed to the water inlet 722, and the other end of the water tank cover 35 is connected to the decorative component body 720.

[0252] like Figure 36 As shown, the water tank cover 35 includes a sealing end 730. The sealing end 730 is sealed to the water inlet 722, through which cleaning fluid or the like can be injected into the water tank. After the liquid is injected, the sealing end of the water tank cover seals the water inlet, preventing liquid from leaking out of the water tank through the inlet.

[0253] like Figure 36 As shown, the water tank cap 35 may also include a fixing end 731. The fixing end 731 is fixed in a groove 722a on the decorative part body 720. For example, the groove 722a may not be located in the part of the decorative part body 34 surrounded by the decorative part rib 721. Thus, the water tank cap can be fixed to the decorative part body by the fixing end 731, preventing the water tank cap from falling off or being lost.

[0254] In some examples, such as Figure 34 , Figure 35 and Figure 36 As shown, the decorative body 720, which forms part of the water tank 701, also includes a first transparent portion 723, which is configured to allow visibility of the water tank 701. This allows observation of the liquid level within the water tank through the first transparent portion, enabling timely replenishment of cleaning fluid.

[0255] For example, the decorative body 720 can be formed of a transparent material such as fiberglass or acrylic. Thus, the part of the decorative body 720 that constitutes the water tank 701 is also transparent, and the water tank can be seen through it.

[0256] For example, the first transparent portion 723 can be formed of a transparent material such as fiberglass or acrylic, and then fixed or snapped onto the decorative body and sealed to it. Of course, the material of the first transparent portion and the way the first transparent portion is joined to the decorative body can also be other forms.

[0257] In some examples, such as Figure 33 , Figure 34 and Figure 36 As shown, the decorative element body 720 also includes a gripping portion 724, which is configured to facilitate gripping of the decorative element 36. Both sides of the gripping portion 724 may have gripping spaces, thereby making it easier and more secure to grip. For example, the gripping portion may also have gripping spaces on only one side, thereby using the other side for the arrangement of other structures or the setting of functions.

[0258] Figure 37 for Figure 36 The decorative element shown is viewed from below. Figure 36 and Figure 37 As shown, the gripping portion 724 is provided with gripping reinforcing ribs 724a, which are located on the same side of the decorative part body as the decorative part ribs 721. Therefore, by providing gripping reinforcing ribs, the strength of the decorative part body and the reliability of the grip can be increased, thereby increasing the service life of the decorative part and the device composed of the decorative part. The gripping portion 724 may have multiple gripping reinforcing ribs 724a, each disposed along the edge of the gripping portion, thereby further increasing the strength of the gripping portion edges.

[0259] One embodiment of this disclosure provides an upper shell assembly. Figure 38 This is an exploded view of an upper shell assembly provided in one embodiment of this disclosure. Figure 38 As shown, the upper shell assembly 750 includes the aforementioned decorative element 36 and upper shell body 30, with the decorative element 36 connected to the upper shell body 30. Figure 39 for Figure 38 Top view of the upper shell assembly shown; Figure 40 for Figure 39 The diagram shows a cross-sectional view of the upper shell assembly along the section line WT. (See diagram below.) Figure 38 , Figure 39 and Figure 40 As shown, one of the decorative part body 720 and the upper shell body 30 is provided with a second snap-fit ​​portion 725a, and the other is fixed together by the second snap-fit ​​portion 725a. The decorative part body 720 is provided with the second snap-fit ​​portion 725a, and the decorative part body 720 is connected to the upper shell body 30 by the second snap-fit ​​portion 725a.

[0260] like Figure 38 , Figure 39 and Figure 40 As shown, the decorative body 720 also includes four extensions 725 extending from the four corners of the gripping portion 724, and each extension 725 is provided with a second snap-fit ​​portion 725a. Thus, the decorative body can be snapped onto the upper shell body via the four second snap-fit ​​portions on the four extensions. The extension length of each of the two extensions 725 closer to the water tank 701 can be less than the extension length of each of the two extensions 725 farther from the water tank 701.

[0261] like Figure 38As shown, the decorative element body 720 is provided with a first fixing part 726, which is located on the side of the decorative element body 720 near the upper shell body 30. The decorative element 36 is connected to the upper shell body 30 through the first fixing part 726 and the first fastener 726a. Thus, the decorative element body can be connected to the upper shell body, forming a stable structure. Simultaneously, the first fixing part also serves a positioning function, ensuring the decorative element is assembled to the upper shell body in the correct position. For example, the first fixing part 726 can also be provided on the upper shell body 30, located on the side of the upper shell body 30 near the decorative element body 720, with the decorative element 36 connected to the upper shell body 30 through the first fixing part 726 and the first fastener 726a.

[0262] Figure 41 for Figure 38 A cross-sectional view of the upper shell assembly along section line EF. (See attached image.) Figure 38 and Figure 41 As shown, the first fixing part 726 may have threads inside that match the first fastener 726a. Therefore, the first fastener 726a can be screwed onto the first fixing part 726 to achieve a fixed connection between the decorative part body 720 and the upper shell body 30. Of course, the connection between the first fixing part and the first fastener to the decorative part body and the upper shell body can also be in other forms. For example, the first fastener is not limited to screws; it can also be a clip or a self-tapping screw. For example, when the first fixing part 726 is provided on the upper shell body 30, the fixed connection between the decorative part body 720 and the upper shell body 30 is similar to that when the first fixing part 726 is provided on the decorative part body 720, and will not be repeated here. The first fixing part 726 can be located in part of the gripping part 724 to strengthen the connection between the gripping part and the upper shell body. There can be multiple first fixing parts 726.

[0263] Figure 38 Taking the first fixing part 726 as a fixing post as an example, the first fixing part 726 can also adopt other suitable forms. Figure 42 for Figure 39 The diagram shows a cross-sectional view of the upper shell assembly along section line GH. In some examples, the tank bottom shell 34 can be connected to the upper shell body 30. This allows the water tank, formed by the tank bottom shell, to be more stably connected to the upper shell body. Simultaneously, the water tank and decorative elements are integrated; the connection between the tank bottom shell and the upper shell body increases the fixing strength between the decorative elements and the upper shell body, thereby increasing the strength and service life of the entire structure. Figure 38 and Figure 42As shown, the water tank bottom shell 34 is provided with a second fixing part 714, which is located on the side of the water tank bottom shell 34 near the upper shell body 30. The water tank bottom shell 34 is connected to the upper shell body 30 through the second fixing part 714 and the second fastener 714a. Simultaneously, the second fixing part also serves a positioning function, ensuring that the water tank formed by the water tank bottom shell and the decorative parts are assembled onto the upper shell body in the correct positions. For example, the second fixing part 714 is also provided on the upper shell body 30, and the water tank bottom shell 34 is connected to the upper shell body 30 through the second fixing part 714 and the second fastener 714a. The second fixing part 714 may have threads inside that match the second fastener 714a, thereby allowing the second fastener 714a to be screwed onto the second fixing part 714, achieving a fixed connection between the water tank bottom shell 34 and the upper shell body 30. Of course, the connection method between the second fixing part and the second fastener for the decorative parts body and the upper shell body can also be other forms. For example, the second fastener is not limited to screws; it can also be a clip or a self-tapping screw, etc. For example, when the second fixing part 714 is provided on the upper shell body 30, the form in which the water tank bottom shell 34 is fixedly connected to the upper shell body 30 is similar to the form in which the second fixing part 714 is provided on the water tank bottom shell 34, and will not be described again here.

[0264] Figure 43 for Figure 38 The exploded top view of the upper shell assembly is shown. Figure 43 As shown, the upper shell body 30 is provided with a recessed area 740 that extends away from the decorative body 720, and the water tank 701 is disposed within the recessed area 740. Therefore, by placing the water tank 701 within the recessed area 740, the size of the upper shell assembly in the direction from the decorative body to the upper shell body can be reduced, thereby reducing the overall size of the upper shell assembly and the device composed of the upper shell assembly. The recessed area 40 may have a similar outline, boundary, or size to the water tank bottom shell 34 and the water tank 701 formed by the water tank bottom shell 34. Thus, the water tank 701 can be disposed within the recessed area 740 without the recessed area 740 occupying the structure and space of other areas of the upper shell assembly 30.

[0265] Figure 44 for Figure 43 The diagram shows a cross-sectional view of the upper shell assembly along section line IJ. (See diagram for reference.) Figure 43 and Figure 44 As shown, the upper housing assembly 750 also includes a button 32 and a seal 751. The button 32 is connected to the upper housing body 30, and the seal 751 is configured to seal the button 32 and the upper housing body 30. Thus, the seal prevents foreign objects such as water, cleaning fluid, or dust from entering the upper housing assembly through the gap between the button and the upper housing body, thereby preventing adverse effects on the upper housing assembly and the device composed of it.

[0266] Figure 45 for Figure 43The diagram shows a cross-sectional view of the upper shell assembly along section line KL. Figure 43 and Figure 44 As shown, the upper housing assembly 750 also includes an indicator light 33, which is connected to the upper housing body 30 and located within the orthographic projection of the decorative component body 720 onto the upper housing body 30. Thus, the decorative component body can protect the indicator light and prevent foreign objects such as water, cleaning fluid, or dust from entering the upper housing assembly through the gap between the indicator light and the upper housing body, thereby preventing adverse effects on the upper housing assembly and the device composed of it.

[0267] like Figure 43 As shown, the decorative component also includes a second transparent portion 727, which is configured as a transparent indicator light. Thus, the flashing of the indicator light can be observed through the second transparent portion to confirm the operating status of the device comprised of the decorative component. The second transparent portion 727 can be formed of a transparent material such as fiberglass or acrylic, and then fixed or snapped onto the decorative component body, forming a sealed connection. Of course, the material of the second transparent portion can also be other forms, and the way the second transparent portion is combined with the decorative component body can also be other forms. For example, the decorative component body 720 can be formed of a transparent material such as fiberglass or acrylic, thereby allowing the indicator light to be seen through the decorative component body.

[0268] like Figure 45 As shown, the upper housing assembly 750 also includes a light guide post 752, which is located on the side of the indicator light 33 near the upper housing body 30. Thus, the light guide post can focus the light emitted by the indicator light.

[0269] Figure 46 This is a schematic diagram of a cleaning device provided in one embodiment of the present disclosure. Figure 47 for Figure 46 An exploded view of the cleaning device shown. Figure 46 and Figure 47 As shown, the cleaning device 1 includes the aforementioned upper shell assembly 750 and lower shell assembly 10, with the upper shell assembly 750 connected to the lower shell assembly 10. Two extensions 725 of the decorative body 720 in the upper shell assembly 750 are snapped onto the upper shell body 30 via two second snap-fit ​​portions 725a. When the upper shell assembly 750 is connected to the lower shell assembly 10, the two second snap-fit ​​portions 725a are snapped between the upper shell body 30 and the lower shell assembly 10; that is, the two snap-fit ​​portions 725a are clamped and fixed by the upper shell body 30 and the lower shell assembly 10. Figure 47 The example given is that two second snap-fit ​​parts 725a are clamped and fixed by the upper shell body 30 and the lower shell assembly 10. Other numbers of second snap-fit ​​parts 725a can also be clamped and fixed, such as one, three or four.

[0270] like Figure 47As shown, the cleaning device 1 may further include a nozzle 31 and a driver 24, with the driver 24 connected to the nozzle 31 and the water tank 701 via pipes. For example, the driver could be a water pump. Thus, the driver can deliver cleaning fluid from the water tank to the nozzle, which sprays the cleaning fluid onto the surface to be cleaned, allowing the cleaning device to clean the surface using the cleaning fluid. Multiple nozzles can be present, each located on the side of the upper housing assembly, to increase the spraying efficiency of the cleaning fluid.

[0271] This disclosure also provides a cleaning device, including any of the lower shell modules described above. Figure 48 This is a partial structural schematic diagram of a cleaning device provided in one embodiment of the present disclosure. Figure 49 This is a cross-sectional schematic diagram of a cleaning device provided in one embodiment of the present disclosure. Figure 50 This is a schematic diagram of a lower shell assembly, a middle cover, and a negative pressure structure provided for an embodiment of this disclosure.

[0272] refer to Figure 48 and Figure 49 The main support structure of the cleaning device 1 is the shell module 01. The shell module 01 includes a lower shell assembly 10, an upper shell assembly 900, and a middle cover 20 located between the lower shell assembly 10 and the upper shell assembly 900. The upper shell assembly 900 includes an upper shell body 30. The lower shell assembly 10 and the upper shell body 30 cooperate to form a receiving cavity 103. The middle cover 20 is located in the receiving cavity 103 and is installed on the lower shell assembly 10. An air cavity is provided between the middle cover 20 and the bottom of the lower shell assembly 10.

[0273] like Figure 48 and Figure 50 As shown, the cleaning device 1 also includes a cleaning module 510, which is located outside the housing module 01 and mounted on the housing module 01. The cleaning module 510 is configured to perform cleaning operations. The cleaning module 510 includes a first module 630, a second module 640, and a drive module. The first module 630 includes a first cleaning frame and a cleaning cloth disposed on the first cleaning frame. The second module 640 includes a linear travel component and a second cleaning frame, and a cleaning cloth disposed on the second cleaning frame. The cleaning device 1 also includes a drive module, which is configured between the first module and the second module. The drive module includes a first drive component and a second drive component. The first drive component can drive the first module 630 to rotate, and the second drive component can drive the second module 640 to rotate, wherein the rotation axes of the first module 630 and the second module 640 are perpendicular to each other.

[0274] Figure 51 This is a structural diagram of a main control board and an auxiliary control board provided in an embodiment of the present disclosure. Figure 52 For public reference only Figure 48 , Figure 50and Figure 51 The cleaning device 1 also includes a control board 5212, which includes a main control board 521 and an auxiliary control board 522. (Reference) Figures 48 to 50 Both the main control board 521 and the auxiliary control board 522 are located within the housing module 01. The orthographic projection of the auxiliary control board 522 onto the lower housing assembly 10 does not overlap with the orthographic projection of the main control board 521 onto the lower housing assembly 10. The main control board 521 and the auxiliary control board 522 are adjacent to each other and spaced apart. The area of ​​the auxiliary control board 522 is smaller than that of the main control board 521. The auxiliary control board 522 is provided to isolate the pressure sensor 540. The auxiliary control board 522 has fewer components, thus having a relatively small area.

[0275] like Figure 51 As shown, the auxiliary control board 522 also includes a support portion 5222, which is used to support the auxiliary control board 522 on the middle cover 20. The support portion 5222 and the auxiliary control board 522 are an integral structure.

[0276] Figure 53 This is a diagram showing the internal structure of a cleaning device according to one embodiment of the present invention. Figure 54 for Figure 53 Enlarged view of the area at point A0 within the rectangular dashed frame. Figure 55 This is a structural diagram of the middle cover of a cleaning device provided in one embodiment. Figure 51 and Figure 53 As shown, the main control board 521 is equipped with a control module 530, which is configured to control the drive module to drive the cleaning module 510. The auxiliary control board 522 is equipped with an air pressure sensor 540, which is configured to detect the air pressure in the air chamber 500. (Reference) Figure 50 and Figure 51 The control module 530 includes a drive control module 5312, which in turn includes a first drive control module 5301 and a second drive control module 5302. (See reference) Figure 51 and Figure 52 The first drive control module 5301 is configured to control the first drive component 14 in the first module 630 to drive the first module 630, and the second drive control module 5302 is configured to control the second drive component 297 in the second module 640 to drive the second module 640. Figure 53As shown, the air cavity 500 is located between the lower housing assembly 10 and the middle cover 20. The control module 530 also includes a pressure sensor control module 5303. For example, the pressure sensor control module 5303 is connected to the pressure sensor 540 on the auxiliary control board 522 to control the pressure sensor 540. Of course, in some other embodiments, the pressure sensor control module 5303 may also be located on the auxiliary control board 522, which is electrically connected to the main control board 521. The control module 530 on the main control board 521 also includes a switch module 5311. The position of the switch module 5311 corresponds to the position of the button on the upper housing assembly 900. For example, the main control board 521 may also include a water pump control module, a step control module, a USB control module, a horn control module, a light control module, a charging control module, a battery control module, and a fan control module, etc. The main control board 521 is electrically connected to the auxiliary control board 522 to facilitate the control of the air pressure sensor 540 on the auxiliary control board 522 and / or to transmit the information sensed by the air pressure sensor 540 to the main control board 521.

[0277] like Figure 53 As shown, the cleaning device also includes a fan 21, an air inlet hood 203, and an air outlet hood 22. The fan 21, air inlet hood 203, and air outlet hood 22 constitute a negative pressure mechanism. (Reference) Figure 53 and Figure 55 The middle cover 20 has a recess with an air inlet 204. The fan 21 is located between the air outlet hood 22 and the recess of the middle cover 20. The air outlet hood 22 is sealed to the periphery of the recess of the middle cover 20. The space between the lower shell assembly 10 and the middle cover 20 forms an air cavity 500. For example, the recess of the middle cover 20 is the air inlet hood 203.

[0278] like Figure 53 , Figure 54 and Figure 55 As shown, the middle cover 20 has an annular rib 552, and a sealing support 561 is provided between the annular rib 552 and the auxiliary control plate 522. The middle cover 20 forms a cavity at the annular rib 552. The cleaning device 1 also includes the sealing support 561, which is located between the auxiliary control plate 522 and the annular rib 552 of the middle cover 20, so that the auxiliary control plate 522 and the middle cover 20 are sealed together. For example, the sealing support 561 can not only provide a sealing function, but also a shock absorption function, eliminating the need for additional shock absorbers and reducing the number of parts and the complexity of the device. For example, the sealing support 561 includes foam, but is not limited to this.

[0279] If the cleaning device includes a single control board, placing the pressure sensor 540 on this single control board would result in an excessively large area of ​​the board. During localized pressure detection, fasteners (e.g., screws) could cause localized deformation of the single control board, affecting its functionality. However, when the pressure sensor is independently mounted on an auxiliary control board 522, which is separate from the main control board 521, the smaller area of ​​the auxiliary control board 522 improves the sealing effect. Simultaneously, it reduces the number of connection points between the main control board 521 and the middle cover 20, preventing excessive localized deformation of the main control board 521 during installation and ensuring its functionality.

[0280] like Figure 53 and Figure 6 As shown, the cleaning device 1 also includes a detection chamber 550, and the middle cover 20 is provided with at least one detection hole 560. The detection chamber 550 and the air chamber 500 are connected through the detection hole 560. The detection hole 560 can balance the air pressure between the air chamber 500 and the detection chamber 550. The detection hole 560 can also reduce the contact of water vapor in the air chamber with the air pressure sensor 540, avoiding instability in the operation of the air pressure sensor and improving the accuracy of air pressure detection. For example, as... Figures 53 to 55 As shown, the detection hole 560 is located in the bottom wall of the concave cavity formed by the annular rib 552.

[0281] Figure 6 A method of mounting the auxiliary control board 522 is shown. For example, the auxiliary control board 522 is mounted on the middle cover 20. For example, see reference... Figure 55 and Figure 6 The auxiliary control board 522 is installed outside the detection cavity 550. For example... Figure 55 and Figure 6 As shown, the middle cover 20 is provided with a second fixing member 572, and the auxiliary control plate 522 is provided with a through hole 5220. Fasteners are fixed to the second fixing member 572 through the through hole 5220 so that the auxiliary control plate 522 is fixed to the middle cover 20. The auxiliary control plate 522 is pressed and fixed by the fasteners. For example, the second fixing member 572 can be a fixing post, and the fastener can be a screw. In one embodiment, the second fixing member is provided with an internal thread in the middle, so that the auxiliary control plate is connected to the middle cover 20 by screws.

[0282] Figure 56 This is a partial schematic diagram of the connection between the main control board and the lower housing assembly, provided for an embodiment of this disclosure. The main control board is mounted on at least one of the lower housing assembly 10 and the middle cover 20. Figure 56 A mounting method for the main control board 521 is shown. (Reference) Figure 48 , Figure 50 , Figure 51 and Figure 56The main control board 521 is mounted on the lower shell assembly 10 and the middle cover 20. The main control board 521 has a notch 5210. The lower shell assembly 10 is provided with a first fixing member 571 on the side closer to the upper shell assembly 900 and the middle cover 20 is provided with a side away from the lower shell assembly 10. The first fixing member 571 is provided with a snap-fit ​​member 5712, which snaps into the notch 5210 so that the main control board 521 is fixed on the lower shell assembly 10.

[0283] like Figure 50 As shown, at least three notches 5210 and at least three first fasteners 571 are provided. The number of notches 5210 is the same as the number of first fasteners 571, and at least three notches 5210 are distributed around the main control board 521. (Reference) Figure 50 and Figure 51 The lower housing assembly 10 is provided with two first fixing members 571, and the middle cover is provided with two first fixing members 571. Of course, the main control board 521 of this disclosure can also adopt other settings, not limited to those shown in the figure.

[0284] like Figure 56 As shown, the snap-fit ​​component 5710 has an annular retaining groove 5712. (Reference) Figure 51 and Figure 56 The fixing groove 5712 is engaged at the notch 5210. For example, the engaging member 5710 is a rubber ring. The engaging member 5710 can be made of various materials such as fluororubber, nitrile rubber, silicone, ethylene propylene rubber, and bisfluororubber, or it can adopt other shapes adapted to the notch 5210. The embodiments of this disclosure do not limit this. By providing the engaging member 5710, damage to the main control board 521 from vibration can be reduced or avoided.

[0285] For example, such as Figure 51 , Figure 55 and Figure 56 As shown, four circular notches 5210 are provided on the main control board, corresponding to the two first fixing parts 571 on the lower shell assembly and the two first fixing parts 571 on the middle cover 20, respectively.

[0286] Figure 57 A perspective view of a cleaning device provided in an embodiment of this disclosure; Figure 58 for Figure 57 A top view of the cleaning device shown; Figure 59 for Figure 58 The cleaning device shown is a cross-sectional view along the section line UV. (See diagram below.) Figure 57 , Figure 58 and Figure 59As shown, the cleaning device 1 includes a housing module 01, a first module 630, a second module 640, and a nozzle 31. The nozzle 31 is connected to the side 30a of the housing module 01 and is configured to spray cleaning liquid. The nozzle 31 is located between the first module 630 and the second module 640, and the spraying direction X of the nozzle 31 is biased towards the first module 630. The nozzle 31 is configured such that the spraying area 800 of the nozzle 31 is within the wiping area 630a of the first module 630. For example, as... Figure 57 and Figure 58 As shown, the nozzle 31, positioned between the first module 630 and the second module 640, divides the wiping area of ​​the cleaning device 1 into two regions: the wiping area 630a of the first module 630 and the wiping area 640a of the second module 640. Thus, the two sides of the nozzle 31 are respectively the wiping areas 630a and 640a of the first module 630. To ensure that the spraying area 800 of the nozzle 31 is within the wiping area 630a of the first module 630, the spray nozzle orifice can be biased towards the wiping area 630a of the first module 630. Simultaneously, the spraying area 800 of the nozzle 31 is not within the wiping area 640a of the second module 640. This embodiment uses a linear nozzle as an example, but is not limited to this; the nozzle shape can be configured as needed, for example, an L-shaped nozzle can also be used. The spraying area 800 of nozzle 31 can be considered as the spraying area 800 of cleaning device 1 when it is stationary or momentarily stationary. Similarly, the wiping areas 630a of the first module 630 and 640a of the second module 640 can be considered as the wiping areas 630a and 640a of the first module 630 and 640a of the second module 640 when the cleaning device is stationary or momentarily stationary. For example, momentary stationary refers to a specific moment during the movement of the cleaning device. By setting the spraying area of ​​the nozzle within the wiping area of ​​the first module, the cleaning device can achieve wet wiping by the first module and dry wiping by the second module. Thus, the cleaning device simultaneously possesses both wet and dry wiping functions. This allows the second module to first perform dry wiping to remove surface dust, followed by wet wiping of the dry-wiped area, avoiding problems such as dust clumping when wet. Alternatively, the first module can first use wet wiping to remove stubborn stains, followed by dry wiping of the wet-wiped area by the second module, preventing the leaving of streaks. Whether the first module or the second module is wiped first, the wiping effect of the cleaning device can be improved.

[0287] Figure 60 for Figure 57 An exploded view of the cleaning device shown. Figure 60As shown, the cleaning device 1 also includes a nozzle bracket 820 and a nozzle bracket fixing base 821. The nozzle 31 is detachably connected to the nozzle bracket 820. The nozzle bracket fixing base 821 is connected to the housing module 01, and the nozzle bracket 820 is detachably connected to the nozzle bracket fixing base 821. The nozzle bracket 820 can be connected to the upper housing body 30 of the housing module 01. The nozzle 31 may include a nozzle mounting part 31a, and the nozzle bracket 820 may include a nozzle bracket mounting part 820a. The nozzle mounting part 31a is connected to the nozzle bracket mounting part 820a, thereby fixing the nozzle to the nozzle bracket. Furthermore, the nozzle 31 is detachably connected to the nozzle bracket 820. Therefore, when the nozzle is damaged or needs cleaning, the nozzle can be disassembled and installed directly from the outside of the cleaning device without disassembling the device, facilitating nozzle maintenance.

[0288] For example, such as Figure 60 As shown, the nozzle mounting part 31a and the nozzle bracket mounting part 820a can be threaded together, that is, the internal thread and the external thread of the nozzle 31 can be connected, so that the nozzle 31 can be installed and removed from the outside of the cleaning device 1. The nozzle installation and removal structure can also be a snap-fit ​​structure, etc.

[0289] In some examples, such as Figure 60 As shown, the nozzle support holder 821 is connected to the housing module 01, and the nozzle support 820 is connected to the nozzle support holder 821. Because the spraying direction X of the nozzle 31 is biased towards the first module 630, directly designing the fixing structure of the nozzle support 820 on the upper housing body 30 would increase the molding difficulty, mold processing cost, and molding time of the upper housing body 30. By separately setting the nozzle support holder 821, connecting the nozzle support 820 to the nozzle support holder 821, and then connecting the nozzle support holder 821 to the housing module 01, the molding difficulty of the housing module 01, mold processing cost, and molding time can be reduced. For example, the nozzle support holder 821 can be connected to the upper housing body 30 of the housing module 01, thereby reducing the molding difficulty of the upper housing body 30, mold processing cost, and molding time.

[0290] For example, such as Figure 60 As shown, the nozzle support mounting base 821 may include an opening 821a and a nozzle support mounting base mounting portion 821b. Correspondingly, the nozzle support 820 may also include a nozzle support mounting portion 820b. The nozzle mounting portion 31a passes through the opening 821a and connects to the nozzle support mounting portion 820a, thereby fixing the nozzle 31 to the nozzle support 820. The nozzle support mounting portion 820b is fixed to the nozzle support mounting base mounting portion 821b, thereby fixing the nozzle support 820 to the nozzle support mounting base 821.

[0291] Figure 61for Figure 58 The cleaning device shown is a cross-sectional view along section line LN. (See diagram below.) Figure 57 , Figure 2 , Figure 59 , Figure 60 and Figure 61 As shown, the upper shell body 30 has a symmetry axis UV, which points from the first module 630 to the second module 640. The angle α1 between the orthographic projection X1 of the nozzle 31 on the mating surface 811 of the upper shell body 30 and the lower shell body 100 and the plane 812 perpendicular to the symmetry axis UV of the upper shell body 30 (as shown in the figure) is as follows: Figure 58 (As shown) Between 25° and 75°, the angle α2 between the orthographic projection X2 of nozzle 31 on plane 812 perpendicular to the axis of symmetry UV of upper shell body 30 and the mating surface 811 of upper shell body 30 and lower shell body 100 (as shown) Figure 61 (As shown) the angle is between 15° and 65°. For example, to achieve better spraying and wet wiping results, the included angle a1 is between 30° and 45°, and the included angle a2 is between 25° and 45°.

[0292] like Figure 57 As shown, the mating surface 811 can be the plane containing the outline of the mating point of the upper shell body 30 and the lower shell body 100, or the plane containing the contact portion of the upper shell body 30 and the lower shell body 100.

[0293] It should be noted that, Figure 57 The spraying direction X of the middle nozzle 31 is the axis of the spraying port; Figure 58 The straight line UV in the diagram can represent either the axis of symmetry UV of the upper shell body 30 or the section line UV. Figure 58 The straight line LN in the figure can represent either the orthographic projection of the plane 812 of the nozzle 31 onto the cleaning device 1, or the cutting line LN. To more clearly represent the included angles a1 and a2, the orthographic projection of the nozzle 31 onto the mating surface 811 is represented by the orthographic projection X1 of the spraying direction X of the nozzle 31 onto the mating surface 811, and the orthographic projection of the nozzle 31 onto the plane 812 is represented by the orthographic projection X2 of the spraying direction X of the nozzle onto the plane 812.

[0294] Therefore, the spraying direction X of nozzle 31 is set within the aforementioned angles a1 and a2, and its spraying area 800 can better cover the wiping area 630a of the first module 630, thereby improving the spraying efficiency of the nozzle and the cleaning efficiency of the cleaning device. The spraying direction X of nozzle 31 can be fixed within the aforementioned angles a1 and a2, i.e., the spraying direction X is not adjustable. Alternatively, the spraying direction X of nozzle 31 can be adjustable within the aforementioned angles a1 and a2, for example, it can be manually adjusted or electrically adjusted by a driver. Therefore, the nozzle can have a more flexible spraying area, allowing the cleaning device to adapt to more cleaning scenarios.

[0295] In some examples, such as Figure 58 and Figure 61 As shown, there are two nozzles 31, which are respectively connected to two sides 30a of the housing module 01. For example, they can be connected to two sides 30a of the upper shell body 30 of the housing module 01. The number of nozzles 31 can also be other values.

[0296] Figure 62 for Figure 57 A bottom view of the upper housing body of the cleaning device shown; Figure 63 for Figure 57 The disassembly diagram of the cleaning device is shown. Figure 62 and Figure 63 As shown, the cleaning device 1 also includes a water tank 701 and a drive 24; the water tank 701 is configured to store cleaning fluid, and the drive 24 is configured to deliver the cleaning fluid from the water tank 701 to the nozzle 31. The upper housing 30 and the lower housing 100 cooperate to form a receiving space 810, within which the drive 24 is located. The drive 24 is connected to the water tank 701 via a pipe 823, and to the nozzle 31 via a pipe 822. Thus, when the water tank 701 contains cleaning fluid, the drive 24 can deliver the cleaning fluid from the water tank 701 to the nozzle 31. It should be noted that, to more clearly illustrate the connection between the drive 24 and the nozzle 31 via pipe 822, and the connection between the drive 24 and the water tank 701 via pipe 823, Figure 62 In the diagram, the actuator 24 on one side 30a of the upper shell 30 is only shown connected to the nozzle 31 via pipe 822, while the other actuator 24 on the other side 30a of the upper shell 30 is only shown connected to the water tank 701 via pipe 823. In practice, each actuator 24 is connected to the nozzle 31 via pipe 822 and to the water tank 701 via pipe 823. It should be noted that... Figure 63The water tank 701 is formed by the bottom shell 34 of the water tank, the decorative rib 721, and the portion of the decorative body 720 surrounded by the decorative rib 721. The bottom shell 34 of the water tank is connected to the decorative rib 721 and is sealed to the decorative rib 721. Of course, the water tank in the embodiments of this disclosure can also be of other forms, such as a freestanding water tank placed in a cleaning device.

[0297] For example, such as Figure 62 and Figure 63 As shown, the actuator 24 includes actuator interface 24a and actuator interface 24b. A actuator interface 24a is connected to a nozzle 31 via a pipe 822, and an actuator interface 24b is connected to a water tank 701 via a pipe 823. Thus, the actuator 24 can deliver cleaning fluid from the water tank 701 to the nozzle 31. The bottom shell 34 of the water tank may be provided with a water outlet 711, and the actuator 24 can be connected to the water outlet 711 of the water tank 701 via a pipe 823. Each actuator 24 is connected to one nozzle 31 via a pipe 822. The upper shell body 30 of the cleaning device 1 has a nozzle 31 on each of its two sides, each nozzle 31 is connected to one actuator 24, and the two actuators 24 are respectively connected to the two water outlets 711 of the water tank 701.

[0298] Figure 64 for Figure 58 The cleaning device shown is a cross-sectional view along the section line OP. Figure 62 and Figure 64 As shown, the upper shell body 30 is connected to the lower shell body 100. The upper shell body 30 includes an upper rib 24c, and the lower shell body 100 includes a lower rib 24d. The driver 24 is disposed between the upper rib 24c and the lower rib 24d. Therefore, the driver can be fixed by the upper rib 24c and the lower rib 24d, eliminating the need for additional structures such as screws, saving material quantity and cost, and improving the assembly efficiency of the cleaning device. Simultaneously, the added upper rib 24c and lower rib also increase the strength of the upper and lower shell bodies. The bottom of the upper rib 24c may also have a retaining claw 24cc. Therefore, the retaining claw 24cc of the upper rib 24c can limit the driver 24, further increasing the fixing strength of the driver.

[0299] In some examples, such as Figure 62 As shown, the upper shell body 30 also includes a snap-fit ​​part 822a and a snap-fit ​​part 823a. The pipe 822 is disposed on the snap-fit ​​part 822a, and the pipe 823 is disposed on the snap-fit ​​part 823a. This allows the pipes 822 and 823 to be securely connected to the upper shell body 30, preventing leaks and other malfunctions in the cleaning device caused by the pipe 822a becoming loose during use.

[0300] For example, the cleaning device provided in the embodiments of this disclosure further includes at least one trip switch, and / or at least one air leak detection hole, a first cleaning element, and a second cleaning element.

Air switch 680 is disposed at at least one end of the cleaning device 1 and is configured to detect the movement position information of the cleaning device 1 and feed the movement position information back to the cleaning device, thereby controlling the movement state of the cleaning device 1. For example, at least one end of the cleaning device 1 includes a first end 683, a second end 682, and a third end 684. Air switch 680 is disposed at the first end 683 of the cleaning device 1, and air switch 681 is disposed at the second end 682 of the cleaning device 1. For example, air switch 680 or air switch 681 may also be disposed at the third end 684 of the cleaning device 1. The first end 683, the second end 682, and the third end 684 of the cleaning device 1 can be located at any edge or corner on the lower housing body 100 of the cleaning device 1 to facilitate detection of the movement state of the cleaning device 1 and prevent the cleaning device 1 from moving outside the area to be cleaned.

[0302] refer to Figure 1A and Figure 2 At least one air leak detection hole may be provided at at least one end of the cleaning device 1, and is configured to detect the movement position information of the cleaning device and feed the movement position information back to the cleaning device, thereby controlling the movement state of the cleaning device.

[0303] For example, the vent detection hole 686 is located at the end of the second module 640 in the second region 687 near the second end 682, or at the end of the first region (not shown) near the first end 683. The first region and the second region 687 are symmetrical with respect to the first plane of symmetry 679. For example, the second region 687 may be the region near the trip switch 681, which facilitates timely detection of the air pressure in the air cavity 658 through the vent detection hole 686 when the cleaning device 1 moves beyond the surface to be cleaned, thus serving as a warning. The vent detection hole 686 and each trip switch can both perform the function of trip detection, providing double protection against falls for the cleaning device 1. For the working principle of the vent detection hole 686, please refer to the aforementioned description of the mating part of the limit post 656 and the limit hole 657 as a vent hole, which will not be repeated here.

[0304] For example, a first cleaning component (not shown) is connected to the side of the first module 630 away from the lower housing body, and a second cleaning component (not shown) is connected to the side of the second module 640 away from the lower housing body. The connection method can be adhesive or snap-fit. The first cleaning component can be connected to a corresponding snap-fit ​​on the first module 630 via a ring-shaped component; the second cleaning component can be connected to a corresponding snap-fit ​​on the second module 640 via a ring-shaped component. The method of fixing the first cleaning component to the first module 630 can be the same as or different from the method of fixing the second cleaning component to the second module 640, and there is no limitation in this regard. The first and second cleaning components can include cleaning cloths or cleaning brushes, as well as other components that can achieve a cleaning effect, and there are no limitations on the materials used.

[0305] For example, such as Figure 5A As shown, in the cleaning device 1, a rectifier structure 691 is provided at the air inlet hood 203 to guide the airflow entering the air chamber 658, so that the airflow can enter the fan 21 more smoothly.

[0306] For example, refer to Figure 1A and Figure 5B In the cleaning device 1, a fan 21 is connected to the middle cover 20. A shock-absorbing component is provided between the fan 21 and the middle cover 20, and another shock-absorbing component is provided between the fan 21 and the air outlet hood 22, so as to play a shock-absorbing role during the operation of the cleaning device 1, thereby protecting the device. The shock-absorbing component can be a silicone ring, or any other component that provides shock absorption and cushioning.

[0307] refer to Figure 1A , Figure 1B and Figure 1C The battery pack 15 is disposed between the upper housing assembly 30 and the lower housing assembly 10. The position of the battery pack 15 is fixed by the ribs 6152 on the upper housing assembly 30 and the ribs 6150 on the lower housing assembly 10. No other fixing elements are required, which can reduce the number of parts in the cleaning device 1. For example, in some embodiments of this disclosure, the battery pack 15 can also be externally mounted in the cleaning device 1 and electronically connected to a circuit board or other circuit board via wires, thereby reducing the weight of the cleaning device 1.
