Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, and in particular to a cleaning module and a cleaning robot. Background Technology

[0002] Robotic vacuum cleaner mop cleaning modules can be broadly categorized into disc-type, tracked type, and roller-type based on their form. Taking the roller-type as an example, its superior cleaning effect is achieved due to its greater pressure on the ground and closer proximity to edges. Current roller-type cleaning modules include multiple moving parts, such as the roller, flip cover, and brushes. However, typically, each cleaning module only has one motor, which, along with a transmission assembly, drives these multiple moving parts individually. This results in excessive motor load during operation, leading to severe overheating and difficulty in heat dissipation. Furthermore, when a single moving part fails, the entire cleaning module must be disassembled for replacement and repair; direct disassembly of the failed part is not possible. Utility Model Content

[0055] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0056] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure).

[0057] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0058] A cleaning robot is a self-propelled cleaning device that can move on surfaces such as floors, carpets, and tiles. Its cleaning module removes dirt, dust, hair, and other debris from the surface. However, in current technologies, the cleaning module typically uses only one motor, which, along with a transmission assembly, drives multiple moving parts. This leads to excessive motor load during operation, causing overheating and poor heat dissipation. Furthermore, when a single moving part fails, the entire cleaning module must be disassembled for replacement and repair, making direct disassembly of the failed part impossible.

[0059] To address the aforementioned issues, this application improves the structure of the cleaning module 100. The cleaning module 100 will be described below in conjunction with the accompanying drawings.

[0060] Please see Figure 1 and Figure 2 The cleaning module 100 includes a support part 1, a cleaning component 2, a fluffing component 3, and a flip-top component 4. The cleaning component 2 includes a cleaning element 21 and a first driving part 22. The cleaning element 21 is movably disposed on the support part 1 to clean the surface to be cleaned, and the first driving part 22 drives and connects to the cleaning element 21. The fluffing component 3 includes a fluffing element 31 and a second driving part 32. The fluffing element 31 is movably disposed on the support part 1 and is disposed corresponding to the cleaning element 21 to fluff the cleaning element 21, and the second driving part 32 drives and connects to the fluffing element 31. The flip-top component 4 includes a flip-top 41 and a third driving part 42. The flip-top 41 is movably disposed on the support part 1 and can be moved to cover or expose the cleaning element 21, and the third driving part 42 drives and connects to the flip-top 41.

[0061] The cleaning module 100 provided by this utility model includes a support part 1, a cleaning component 2, a fluffing component 3, and a flip-top component 4; the cleaning component 2 includes a cleaning element 21 and a first drive part 22, the first drive part 22 drives the cleaning element 21 to move, so as to clean the surface to be cleaned when the cleaning robot walks. The cleaning element 21 can be a flexible cloth or a roller brush, and there is no specific limitation here.

[0062] Understandably, after cleaning, the cleaning component 21 is flattened under the pressure of the cleaning robot and the surface to be cleaned. By providing a fluffing component 31 and a second drive unit 32, the second drive unit 32 drives the fluffing component 31 to move, thus fluffing the cleaning component 21. This allows the cleaning component 21 to maintain a fluffed state during the cleaning process of the cleaning robot, thereby reducing the cleaning frequency of the cleaning component 21. The fluffing component 31 can be a brush or a fluffing roller 311; no specific limitation is made here.

[0063] Furthermore, during the cleaning robot's movement, it will pass through surfaces that do not require cleaning or cannot be cleaned. When the cleaning robot is in wet cleaning mode, the cleaning component 21 is wet, and wastewater can easily fall from the cleaning component 21 onto the surfaces it passes through. By setting a flip cover 41 and a third drive unit 42, the third drive unit 42 can drive the flip cover 41 to move. When the cleaning robot passes through a surface to be cleaned, the flip cover 41 moves to expose the cleaning component 21 for cleaning; when the cleaning robot passes through a surface that does not require cleaning, the flip cover 41 moves to cover the cleaning component 21, thereby isolating the cleaning component 21 from the surface that does not require cleaning, so as to better protect the surface that does not require cleaning and improve the cleaning quality.

[0064] In the cleaning module 100 of this utility model, a first driving unit 22 drives the cleaning component 21, a second driving unit 32 drives the fluffing component 31, and a third driving unit 42 drives the flip cover 41. By using three driving units to drive the components separately, the load on each driving unit can be reduced, solving the problem of heat dissipation difficulties caused by severe heat generation and heat accumulation in the driving components. Furthermore, the cleaning component 21, fluffing component 31, and flip cover 41 are each driven by an independent driving unit. When some components fail, the failed component can be disassembled individually without affecting other components, facilitating user operation.

[0065] It should be noted that the support part 1 is the basic structure of the cleaning module 100 and can provide a supporting base for other components, such as supporting the cleaning component 21, the fluffing roller 311, and the flip cover 41. The support part 1 can be a bracket or a housing 11, and there is no specific limitation here.

[0066] This application does not impose specific restrictions on the location of the driving component; the driving component can be located at any position on the support part 1.

[0067] Understandably, the cleaning robot has a body, which includes a chassis and a top cover. A receiving cavity is formed between the chassis and the top cover to house the cleaning module 100. A first opening is provided on the side of the chassis away from the top cover so that a partial cleaning component 21 can be exposed from the first opening so that the surface to be cleaned can be cleaned when the cleaning robot moves.

[0068] Meanwhile, a second opening is provided on the side wall of the chassis, allowing the cleaning module 100 to be movable within the body and able to extend to an outward-swinging position, at which point a portion of the cleaning module 100 protrudes from the second opening. When the cleaning robot encounters an obstacle and is unable to clean the surface to be cleaned, the cleaning module 100 moves to the outward-swinging position, and the cleaning module 100 extending from the second opening can clean hard-to-reach areas. The side of the cleaning module 100 that can extend from the second opening is designated as the outward-swinging side a, and the side opposite to the outward-swinging side a is designated as the non-outward-swinging side b.

[0069] To further enhance the cleaning effect, in one embodiment, please refer to... Figure 1 and Figure 2 The first drive unit 22 is located near the non-outward swing side b, and the second drive unit 32 and the third drive unit 42 are located on the non-outward swing side b. In this way, the first drive unit 22, the second drive unit 32 and the third drive unit 42 will not occupy the space of the cleaning module 100 on the outward swing side a. Therefore, when the cleaning module 100 cleans the dead corners, the outward swing side a of the cleaning module 100 can get closer to the corners and achieve a better edge-fitting effect, thereby improving the cleaning quality.

[0070] It is understandable that the first drive unit 22 is located closer to the non-outward swing side b, while the second drive unit 32 and the third drive unit 42 are located on the non-outward swing side b. In this case, the cleaning module 100 is heavier on the corresponding non-outward swing side b, which can cause the cleaning robot to become unbalanced. To solve this problem, in one embodiment, please refer to... Figure 1 The cleaning module 100 also includes a counterweight 5, which is located on the support 1 and close to the outward swing side a. By setting the counterweight 5, the weight of the drive unit is offset to a certain extent, thereby making the weight of the cleaning module 100 balanced on the outward swing side a and the non-outward swing side b, thus ensuring that the cleaning robot is more balanced during walking and improving the cleaning quality.

[0071] As mentioned above, the support part 1 can be either a bracket or a housing 11. The following explanation uses the example of "the support part 1 being a housing 11" to illustrate the specific installation position of the drive component.

[0072] Please refer to further information. Figure 1 and Figure 2 The support part 1 includes a columnar housing 11, on which an outward swing side a and a non-outward swing side b are respectively formed on both sides of the housing 11 in the axial direction. An inner cavity 12 is formed inside the housing 11, and one of its radial inner walls penetrates the housing 11 to form an opening 13 that connects to the inner cavity 12. A cleaning component 21 is movably disposed in the inner cavity 12 and partially exposed from the opening 13. A fluffing component 31 is movably disposed in the housing 11. A flip cover 41 is movably disposed in the housing 11. A first driving part 22 is disposed in the inner cavity 12, and a second driving part 32 and a third driving part 42 are both disposed on the outside of the housing 11.

[0073] Specifically, the cleaning component 21 is rotatably mounted in the inner cavity 12 along the central axis of the housing 11; the housing 11 has a first inner wall 14 on the non-outward swing side b; the first drive unit 22 includes a first motor 221; the output axis of the first motor 221 is arranged parallel to the central axis of the housing 11; the motor mount of the first motor 221 is located on the first inner wall 14; and the output shaft of the first motor 221 drives and connects to the cleaning component 21.

[0074] In other words, the cleaning component 21 is rotatably mounted in the inner cavity 12 along the central axis of the housing 11, and its part is exposed from the opening 13 of the housing 11 so that the cleaning component 21 can clean the surface to be cleaned during the walking of the cleaning robot; at the same time, the first motor 221 drives the cleaning component 21 to rotate. The first motor 221 is located in the inner cavity 12 and is provided on the first inner wall 14 near the non-outward swing side b, so that the structure of the cleaning component 2 is more compact.

[0075] Please see Figure 3In one embodiment, the fluffing member 31 is arranged parallel to and interference-fitted with the cleaning member 21, and the fluffing member 31 is rotatably mounted in the inner cavity 12 along its central axis; the housing 11 has a first outer wall 15 in the direction away from the opening 13 and a second outer wall 16 on the non-outward swing side b; the cleaning module 100 also includes a mounting plate 17, which is disposed on the outside of the housing 11 and is arranged parallel to the second outer wall 16. The mounting plate 17 has a first surface on the same side as the first outer wall 15, and a mounting groove is provided on the first surface; the second drive unit 32 includes a second motor 321 and a first gearbox 322; the second motor 321 is disposed in the mounting groove, and its output shaft is disposed facing the first outer wall 15 so that its output shaft is parallel to the central axis of the housing 11; the first gearbox 322 is disposed on the side of the mounting plate 17 facing the first outer wall 15, its input end is drivenly connected to the output shaft of the second motor 321, and its output end passes through the mounting plate 17 and is drivenly connected to the fluffing member 31.

[0076] In this embodiment, the fluffing component 31 is rotatably mounted in the inner cavity 12 along its central axis and is interference-fitted with the cleaning component 21 so that the cleaning component 21 can be fluffed during the rotation of the fluffing component 31. At the same time, a mounting plate 17 is provided on the outer side of the housing 11. The mounting plate 17 is arranged parallel to the second outer wall 16. By integrating the second motor 321 and the first gearbox 322 on the mounting plate 17, the structure of the second drive unit 32 is compact and the layout is reasonable.

[0077] Furthermore, as mentioned above, the second drive unit 32 and the third drive unit 42 are arranged on the same side. Please refer to [link / reference]. Figure 8 and Figure 9 The flip cover 41 is rotatably mounted on the outside of the housing 11 around the central axis of the housing 11, and can rotate to close or open the opening 13; the third drive unit 42 includes a third motor 421 and a second gearbox 422; the third motor 421 is located on the first outer wall 15 and close to the second outer wall 16, the third motor 421 and the second motor 321 are arranged side by side, and its output shaft is arranged towards the second outer wall 16, so that the output axis of the third motor 421 is parallel to the output axis of the second motor 321; the second gearbox 422 is located on the second outer wall 16, the input end of the second gearbox 422 is drivenly connected to the output shaft of the third motor 421, and its output end is drivenly connected to the flip cover 41.

[0078] In this embodiment, the flip cover 41 is rotatably mounted on the outside of the housing 11 around the central axis of the housing 11, and can rotate to close or open the opening 13. Meanwhile, the third motor 421 is disposed on the first outer wall 15 and close to the second outer wall 16, with the third motor 421 and the second motor 321 arranged side-by-side and their output axes parallel. The second reduction gearbox 422 is disposed on the second outer wall 16 and is drively connected to the third motor 421 and the flip cover 41. Thus, the second drive unit 32 and the third drive unit 42 are integrated on the non-outward swing side b, making the cleaning module 100 structurally compact and reducing the space occupied by the cleaning module 100.

[0079] Specifically, please refer to Figure 8 The support part 1 also includes a decorative cover 18, which is disposed on the second outer wall 16 and covers the second gearbox 422, thereby improving the appearance of the cleaning module 100.

[0080] As mentioned above, the cleaning component 21 can be a flexible cloth or a roller brush. The following will provide a specific explanation using the example of "the cleaning component 21 being a flexible cloth".

[0081] Please see Figure 2 In one embodiment, the cleaning component 2 further includes a roller 23, which has an outward swing side a and a non-outward swing side b on both sides of its axial direction. The roller 23 is rotatably mounted on the support part 1 along its central axis. The cleaning component 21 is disposed on the outer periphery of the roller 23 and rotates coaxially with the roller 23. The roller 23 is hollow and has a connecting part 24 inside. The first drive part 22 is disposed near the non-outward swing side b. The first drive part 22 includes a first motor 221. The output axis of the first motor 221 coincides with the central axis of the roller 23. The motor mount of the first motor 221 is disposed on the support part 1 and is at least partially housed in the roller 23. The output shaft of the first motor 221 is near the connecting part 24 and is drivenly connected to the connecting part 24.

[0082] Please see Figure 3 In one embodiment, the fluffing component 31 includes a fluffing roller 311, which is parallel to and interference-fitted with the roller 23. The fluffing roller 311 is rotatably mounted on the support part 1 along its central axis. A second drive part 32 is located near the non-outward swing side b, and its drive axis is parallel to the drive axis of the first drive part 22. The second drive part 32 drives and connects to the fluffing roller 311. By providing the fluffing roller 311, the cloth on the outer periphery of the roller 23 can be fluffed during the rotation of the fluffing roller 311 along its central axis.

[0083] Specifically, the fluffing roller 311 includes a first roller shaft and a fluffing hook. The first roller shaft is arranged parallel to the roller 23 and is rotatably mounted on the support part 1 along its central axis. The fluffing hook covers the outer periphery of the first roller shaft so that the fluffing hook can lift the lint on the surface of the cloth during the rotation of the first roller shaft along its central axis, thereby achieving fluffing.

[0084] To ensure the fluffy effect of the fluffing roller 311, in one embodiment, the axial distance between the fluffing roller 311 and the roller 23 is greater than 0 mm and less than or equal to 6 mm. Preferably, the axial distance between the fluffing roller 311 and the roller 23 is greater than or equal to 0.5 mm and less than or equal to 2.5 mm; more preferably, the axial distance between the fluffing roller 311 and the roller 23 is 1 mm.

[0085] Furthermore, the fluffing roller 311 has a first end 3111 and a second end 3112 opposite each other in its axial direction, wherein:

[0086] In this application, please refer to Figure 4 and Figure 5 The support part 1 has a mounting block 33 at a position near the outer swing side a. The first end 3111 is rotatably mounted on the mounting block 33 through the first insertion structure 34. It can be understood that the fluffing roller 311 is rotatably mounted on the support part 1.
