Description

Technical Field

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

[0002] Cleaning equipment can be used in environments such as homes, offices, shopping malls, and factories. Taking a robotic vacuum cleaner as an example, the chassis of a robotic vacuum cleaner is usually equipped with a walking component and a cleaning component. When the walking component moves on the supporting surface, the cleaning component can clean the surface it passes over, including but not limited to mopping and vacuuming.

[0003] In related technologies, when a robotic vacuum cleaner encounters steps or carpets, it raises its cleaning components to maintain a distance from the surface. However, due to the limited lifting height of the cleaning components, taking a scenario where the walking component traverses steps as an example, the cleaning component may scrape against the step surface, scraping off dirty water from the cleaning component and contaminating the surface it traverses. Similarly, taking a scenario where the walking component traverses a long-pile carpet as another example, the cleaning component may come into contact with the carpet, wetting and contaminating the surface it traverses. Utility Model Content

[0004] The main purpose of this invention is to propose a cleaning module and cleaning equipment, which aims to solve the problem of contamination of the path surface by cleaning components in related technologies.

[0005] To achieve the above objectives, this utility model proposes a cleaning module, comprising:

[0006] Support section;

[0007] A cleaning assembly, including a cleaning element disposed on a support portion, for cleaning the pathway surface; and,

[0008] A shielding assembly is provided on the support portion. The shielding assembly includes two movably disposed shielding portions. The two shielding portions are located on the outside of the cleaning component and can move relative to each other. The two shielding portions have a shielding position and an open position during their movement stroke. In the shielding position, the two shielding portions are mated together and isolate the cleaning component from the path surface. In the open position, the two shielding portions are separated so that the cleaning component is exposed and comes into contact with the path surface.

[0009] Preferably, the shielding part can move around the circumference of the cleaning component, and the two shielding parts can be connected or separated along the circumference of the cleaning component.

[0010] Preferably, the shielding part includes a first baffle and a second baffle stacked radially on the cleaning component. The first baffle is movably disposed on the support part and can rotate around the cleaning component in the circumferential direction. The second baffle is movably disposed on the first baffle and can rotate around the cleaning component in the circumferential direction. During the movement of the second baffle, the second baffle has an unfolded state that is partially misaligned with the first baffle and a retracted state that is at least partially overlapped with the first baffle.

[0016] The first baffle and the second baffle are respectively provided with a first abutting part and a second abutting part. When the second baffle moves to the maximum unfolded position, the first abutting part and the second abutting part abut against each other. This is so that when the second baffle continues to move along the circumference of the cleaning part, it can drive the first baffle to move synchronously, so that the opposite sides of the two second baffles can move and connect.

[0017] Preferably, the shielding assembly further includes two limiting structures respectively provided for the two shielding parts, each limiting structure including a limiting part and a mating part;

[0018] The limiting part and the mating part are provided, one of which is provided on the first baffle and the other is provided on the support part. The limiting part is used to limit and cooperate with the mating part when the blocking part is in the blocking position, so as to limit and fix the first baffle and the support part.

[0019] Preferably, the cleaning module further includes a shielding drive assembly, which includes a shielding drive unit and a shielding transmission assembly, and the shielding transmission assembly drives the shielding drive unit and the two shielding units.

[0020] Preferably, the shielding part can move around the circumference of the cleaning part, and the two shielding parts can move relative to each other;

[0026] Preferably, the output section includes:

[0027] The second worm gear includes a second worm wheel and a second worm that mesh with each other. The second worm wheel is connected to the input part for transmission, and the second worm is arranged in the same direction as the output shaft of the first motor.

[0028] The first gear and rack assembly includes a first gear and a first rack that mesh with each other. The first gear is sleeved on the outside of the second worm and rotates coaxially with the second worm. The first rack is flexibly arranged and is connected to the shielding part for transmission.

[0029] Preferably, the output section includes a second gear and rack assembly, which includes a second gear and a second rack that mesh with each other. The second gear is driven to the input section, and the second rack is arranged radially along the cleaning member and is driven to the shielding section.

[0034] This utility model also proposes a cleaning device, including the above-mentioned cleaning module.

[0035] The technical solution provided by this utility model has at least the following advantages:

[0036] The cleaning module provided by this utility model includes a support, a cleaning component, and a shielding component. The cleaning component includes a cleaning part for cleaning the surface to be cleaned. Two shielding parts are provided on the support, located on the outside of the cleaning part and movable relative to each other. When the cleaning device moves, if the cleaning part needs to clean the surface it passes through, the two shielding parts move relative to each other to the open position. At this time, the two shielding parts separate, exposing the cleaning part and allowing it to contact the surface, enabling the cleaning part to clean the surface smoothly. When the surface that the cleaning device passes through does not need to be cleaned, the two shielding parts move relative to each other to the shielding position. At this time, the two shielding parts are engaged, isolating the cleaning part from the surface, thus preventing the cleaning part from contacting the surface and avoiding wastewater from the cleaning part from contaminating the surface.

[0051] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0052] 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.

[0053] 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). If the specific posture changes, the directional indicators will also change accordingly.

[0054] 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.

[0055] Cleaning equipment can be used in environments such as homes, offices, shopping malls, and factories. Cleaning equipment can be handheld or self-propelled. Taking cleaning robots as an example, they can move across surfaces such as floors, carpets, and tiles. The cleaning module of the robot can clean the surface to be cleaned, removing dirt, dust, hair, and other debris. However, not all surfaces along the robot's path need to be cleaned during its movement.

[0056] To prevent wastewater from contaminating surfaces that do not require cleaning when the cleaning equipment passes over such surfaces, this invention improves the structure of the cleaning module 100, which will be described below with reference to the accompanying drawings.

[0057] Please see Figure 1 , Figure 2 and Figure 7 The cleaning module 100 includes a support portion 1, a cleaning component 2, and a shielding component 3. The cleaning component 2 includes a cleaning element 21 disposed on the support portion 1 for cleaning the path surface. The shielding component 3 is disposed on the support portion 1 and includes two movably disposed shielding portions 31 located outside the cleaning element 21 and movable relative to each other. The two shielding portions 31 have a shielding position and an open position during their travel. In the shielding position, the two shielding portions 31 are mated, isolating the cleaning element 21 from the path surface. In the open position, the two shielding portions 31 are separated, exposing the cleaning element 21 and allowing it to contact the path surface.

[0058] The cleaning module 100 provided by this utility model includes a support part 1, a cleaning component 2, and a shielding component 3. The cleaning component 2 includes a cleaning element 21 for cleaning the surface to be cleaned. Two shielding parts 31 are provided on the support part 1, and the two shielding parts 31 are located outside the cleaning element 21 and can move relative to each other.

[0059] When the cleaning equipment moves forward, the cleaning component 21 needs to clean the surface it passes through. The two blocking parts 31 move relative to each other to the open position. At this time, the two blocking parts 31 separate, so that the cleaning component 21 is exposed and comes into contact with the surface it passes through, and the cleaning component 21 can clean the surface it passes through smoothly.

[0060] When the surface that the cleaning equipment passes over does not need to be cleaned, the two blocking parts 31 move to the blocking position relative to each other. At this time, the two blocking parts 31 are connected and isolate the cleaning component 21 from the surface it passes over, so that the cleaning component 21 will not come into contact with the surface it passes over, thereby preventing the wastewater from the cleaning component 21 from contaminating the surface it passes over.

[0061] This disclosure does not impose specific limitations on the movement of the shielding part 31. In one embodiment, the shielding part 31 can move around the circumference F2 of the cleaning member 21, and the two shielding parts 31 can be moved to dock or separate along the circumference F2 of the cleaning member 21.

[0062] This disclosure does not impose specific limitations on the structure of the cleaning component 21. In one embodiment, the cleaning component 21 is configured as a roller brush. In another embodiment, the cleaning component 21 is configured as a tracked cloth.

[0063] It is understood that, regardless of whether the cleaning component 21 is configured as a roller brush or a conveyor belt wipe, the outer peripheral contour of the cleaning component 21 is at least partially arc-shaped. In one embodiment, please refer to... Figure 1 The shielding part 31 includes an arc-shaped baffle 311 movably disposed on the support part 1. The arc-shaped baffle 311 is located on the outside of the cleaning member 21 and can move around in a circumferential direction F2 along the cleaning member 21. The two arc-shaped baffles 311 can move relative to each other.

[0064] In the shielded position, the two opposing sides of the two arc-shaped baffles 311 meet and isolate the cleaning component 21 from the surface to be cleaned. In the open position, the opposing sides of the two arc-shaped baffles 311 separate, exposing the cleaning component 21 and allowing it to contact the surface to be cleaned. In this embodiment, by providing the arc-shaped baffles 311, the shielding portion 31 is adapted to the outer peripheral contour of the cleaning component 21, thereby making the shielding portion 31 and the cleaning component 21 fit together compactly and saving installation space.

[0065] Continuing from the previous statement that "the shielding part 31 can rotate around the circumference F2 of the cleaning component 21, and the two shielding parts 31 can be movably connected or separated along the circumference F2 of the cleaning component 21," when the size of the cleaning component 21 is large, such as a track rag, in order to completely isolate the track rag from the path surface at the shielding position, the radial dimension F3 of the shielding part 31 is much larger than the radial dimension F3 of the track rag roller, which increases the overall size of the cleaning module 100. To solve this problem, please refer to... Figure 2 and Figure 7 In one embodiment of the present invention, the shielding part 31 is configured as a first baffle 312 and a second baffle 313 stacked together.

[0066] Please see Figures 3 to 8 The shielding portion 31 includes a first baffle 312 and a second baffle 313 stacked radially F3 on the cleaning member 21. The first baffle 312 is movably disposed on the support portion 1 and can rotate around the cleaning member 21 in the circumferential direction F2. The second baffle 313 is movably disposed on the first baffle 312 and can rotate around the cleaning member 21 in the circumferential direction F2. During the movement of the second baffle 313, the second baffle 313 has an unfolded state that is partially misaligned with the first baffle 312, and a retracted state that at least partially overlaps with the first baffle 312.

[0067] In the obstructed position, the second baffle 313 is in an unfolded state, with its opposite sides joined together. In the open position, the second baffle 313 is in a retracted state, with its opposite sides separated.

[0068] In this embodiment, the shielding portion 31 includes a first baffle 312 and a second baffle 313 stacked together. The size of the coverage area of ​​the shielding portion 31 is adjusted by the relative movement of the first baffle 312 and the second baffle 313. For smaller cleaning components 21, the second baffle 313 can be moved and retracted relative to the first baffle 312, thereby reducing the overall size of the shielding portion 31 while ensuring the isolation of the cleaning components 21.

[0069] For the larger cleaning component 21, the second baffle 313 can be movably unfolded relative to the first baffle 312. At this time, the first baffle 312 and the second baffle 313 are joined to form a large-area shielding portion 31, achieving isolation of the cleaning component 21. Furthermore, since the first baffle 312 and the second baffle 313 unfold to form the shielding portion 31, the individual dimensions of the first baffle 312 and the second baffle 313 do not need to be designed to be large. The shapes of the first baffle 312 and the second baffle 313 can also be designed to fit the outer periphery of the cleaning component 21, further reducing the overall size of the cleaning module 100.

[0070] This disclosure does not impose specific limitations on the stacking arrangement of the first baffle 312 and the second baffle 313. In one embodiment, the first baffle 312 and the second baffle 313 are stacked side by side on the radial direction F3 of the cleaning member 21.

[0071] To further reduce the volume of the shielding portion 31, in one embodiment, please refer to... Figures 2 to 8 The first baffle 312 forms a receiving cavity 3121 with an opening 3122 on one side, and the opening 3122 is disposed away from the support part 1. The second baffle 313 is slidably installed in the receiving cavity 3121 so that the second baffle 313 extends at least partially from the opening 3122 in the unfolded state and is received into the receiving cavity 3121 from the opening 3122 in the retracted state.

[0072] In this embodiment, the first baffle 312 is designed to be hollow, forming a receiving cavity 3121 inside. A second baffle 313 is movably disposed within the receiving cavity 3121. During the movement of the second baffle 313, it can be retracted into the receiving cavity 3121 or extend from the opening 3122 of the receiving cavity 3121. Thus, while achieving movable retraction or expansion, the size of the shielding portion 31 in the radial direction F3 of the cleaning member 21 can be reduced, thereby further reducing the volume of the shielding portion 31.

[0073] When the blocking part 31 switches between the blocked position and the open position, the second baffle 313 moves relative to the first baffle 312. To ensure the stability of the movement of the second baffle 313, in one embodiment, please refer to... Figure 6 The shielding assembly 3 also includes two first guide structures 33 respectively provided for the two shielding parts 31. Each first guide structure 33 includes a guide groove 331 and a guide rib 332 for guiding cooperation, and both the guide groove 331 and the guide rib 332 extend along the circumferential direction F2 of the cleaning member 21. One of the guide groove 331 and the guide rib 332 is provided on the first baffle 312, and the other is provided on the support part 1. By providing the first guide structure 33, the second baffle 313 is guided, thereby making the movement of the second baffle 313 more stable.

[0074] It is understandable that when the second baffle 313 is in the unfolded state, it can extend partially relative to the first baffle 312, or it can extend relative to the first baffle 312 to be in the fully unfolded position.

[0075] For the smaller cleaning component 21, when the second baffle 313 is partially unfolded relative to the first baffle 312, the opposite sides of the two second baffles 313 can be joined together. At this time, the first baffle 312 does not need to move to complete the isolation of the cleaning component 21 and the surface it passes through.

[0076] For the larger cleaning component 21, when the second baffle 313 moves to its maximum open position relative to the first baffle 312, the opposite sides of the two second baffles 313 align. At this time, the first baffle 312 does not need to move, thus completing the isolation of the cleaning component 21 from the surface it passes through.

[0077] For a particularly large cleaning component 21, when the second baffle 313 is moved to its maximum open position relative to the first baffle 312, the opposite sides of the two second baffles 313 still cannot be aligned. At this time, the first baffle 312 needs to move relative to the support 1 so that the opposite sides of the two second baffles 313 can be aligned, thereby completing the isolation of the cleaning component 21 and the path surface.

[0078] To facilitate the linkage between the first baffle 312 and the second baffle 313, in one embodiment, please refer to... Figure 2 and Figure 7 The first baffle 312 and the second baffle 313 are respectively provided with a first abutting part 44 and abutting part 45. When the second baffle 313 moves to the maximum unfolded position, the first abutting part 44 and the second abutting part 45 abut against each other, so that when the second baffle 313 continues to move along the circumferential direction F2 of the cleaning member 21, it can drive the first baffle 312 to move synchronously, so that the opposite sides of the two second baffles 313 can move and connect.

[0079] In other words, the first baffle 312 and the second baffle 313 are respectively provided with a first abutting part 44 and abutting part 45. When the second baffle 313 moves to its maximum open position relative to the first baffle 312, the opposite sides of the two second baffles 313 still cannot be connected. At this time, the first abutting part 44 and the second abutting part 45 abut against each other. When the second baffle 313 continues to move along the circumferential direction F2 of the cleaning member 21, it drives the first baffle 312 to move relative to the support part 1, thereby enabling the opposite sides of the two second baffles 313 to move and connect.

[0080] When the first baffle 312 moves relative to the support 1, causing the opposite sides of the two second baffles 313 to engage, the blocking part 31 is in the blocking position. To limit the travel of the first baffle 312, in one embodiment, please refer to... Figure 4 and Figure 5 The shielding component 3 also includes two limiting structures 32 respectively provided for the two shielding parts 31, each limiting structure 32 including a limiting part 321 and a mating part 322.

[0081] The limiting part 321 and the mating part 322 are respectively provided on the first baffle 312 and the other on the support part 1. The limiting part 321 is used to limit and cooperate with the mating part 322 when the blocking part 31 is in the blocking position, so that the first baffle 312 and the support part 1 are limited and fixed.

[0082] It should be noted that at least two first abutment portions 44 are provided, and the two first abutment portions 44 are arranged side by side at intervals in the circumferential direction of the cleaning member 21. When the second baffle 313 moves relative to the first baffle 312 to its maximum open position, the second abutment portion 45 abuts against one of the first abutment portions 44. And when the second baffle 313 continues to move along the circumferential direction F2 of the cleaning member 21, it drives the first baffle 312 to move relative to the support portion 1, so that the two first baffles 312 move towards each other, thereby allowing the opposite sides of the two second baffles 313 to move and connect.

[0083] When the second baffle 313 moves relative to the first baffle 312 until it is completely housed within the receiving cavity 3121, the second abutting part 45 abuts against another first abutting part 44. Furthermore, as the second baffle 313 continues to move along the circumferential direction F2 of the cleaning member 21, it causes the first baffle 312 to move relative to the support part 1, so that the two first baffles 312 move in opposite directions, thereby allowing the opposing sides of the two second baffles 313 to move and separate.

[0084] Continuing from the previous section, "The first baffle 312 is designed to be hollow, forming a receiving cavity 3121. The second baffle 313 is movably disposed within the receiving cavity 3121." To facilitate the placement of the first abutment portion 44 and the second abutment portion 45, and to save installation space, in one embodiment, the first baffle 312 has a window communicating with the receiving cavity 3121 on its surface opposite to the cleaning member 21, and a portion of the second baffle 313 is exposed from the window. A second abutment portion 45 protrudes from the exposed position of the second baffle 313, and two first abutment portions 44 are respectively formed on the two opposite sides of the window in the circumferential direction of the cleaning member 21.

[0085] When the second baffle 313 moves to its maximum open position relative to the first baffle 312, the second abutting part 45 abuts against one side of the window. When the second baffle 313 moves to be fully retracted into the receiving cavity 3121 relative to the first baffle 312, the second abutting part 45 abuts against the other side of the window.

[0086] In one embodiment, please refer to Figure 9 and Figure 10 The cleaning module 100 also includes a shielding drive assembly 4, which includes a shielding drive part 41 and a shielding transmission assembly 42, which are movably configured to drive the shielding drive part 41 and the two shielding parts 31.

[0087] Specifically, the shielding part 31 can rotate around the circumference F2 of the cleaning member 21, and the two shielding parts 31 can move relative to each other. The shielding drive part 41 includes a first motor 411, and the output shaft of the first motor 411 is arranged along the axial direction F1 of the cleaning member 21.

[0088] The shielding transmission assembly 42 includes an input section 421 and two output sections 422 that are connected in a transmission connection. The input section 421 is drivenly connected to the output shaft of the first motor 411. The two output sections 422 are movable relative to each other, and each output section 422 is connected in a transmission connection to a shielding section 31.

[0089] In this embodiment, the blocking drive assembly 4 includes a first motor 411 and a blocking transmission assembly 42. The output shaft of the first motor 411 is driven to the input section 421 of the blocking transmission assembly 42, and the input section 421 is driven to the two blocking sections 31 through two output sections 422 respectively. In this way, the first motor 411 and the blocking transmission assembly 42 can achieve synchronous driving of the two blocking sections 31.

[0090] Please see Figure 9 and Figure 10 The input section 421 includes a first worm gear 4211 and a gear transmission structure 4212. The first worm gear 4211 includes a first worm wheel and a first worm that mesh with each other. The first worm is coaxially arranged with and driven by the output shaft of the first motor 411. The gear transmission structure 4212 includes a driving gear and a driven gear that are connected in a transmission relationship. The driving gear meshes with the first worm wheel. The driven gear is connected in a transmission relationship with the two output sections 422, so that the two output sections 422 can move relative to each other in the circumferential direction F2 of the cleaning component 21.

[0091] Understandably, in order to ensure normal transmission, the lead angle of the first worm gear, as the input tooth, must be greater than the friction angle. This is to ensure that the first worm gear 4211 can transmit normally without self-locking.

[0092] In one embodiment, please refer to Figure 9 The output section 422 includes a second worm gear 4221 and a first gear and rack assembly 4222. The second worm gear 4221 includes a second worm wheel and a second worm that mesh with each other. The second worm wheel is drive-connected to the input section 421. The second worm is arranged in the same direction as the output shaft of the first motor 411. The first gear and rack assembly 4222 includes a first gear and a first rack that mesh with each other. The first gear is sleeved on the outside of the second worm and rotates coaxially with the second worm. The first rack is flexibly arranged and drive-connected to the shielding section 31.

[0093] The system comprises two second worm gears, located on either side of the second worm wheel, both meshing with the second worm wheel. When the input unit 421 drives the second worm wheel to rotate, it simultaneously drives the two second worm gears to rotate in opposite directions.

[0094] Correspondingly, two first gear rack assemblies 4222 are also provided, each first gear rack assembly 4222 corresponding to a second worm gear. The two first racks move in opposite directions, so that the two second racks can respectively drive the two blocking parts 31 to move relative to each other.

[0095] Based on the structure of this embodiment, the movement of the blocking drive assembly 4 will be described in detail below. The blocking drive assembly 4 includes a first motor 411, a first worm gear 4211, a gear transmission structure 4212, a second worm gear 4221, and a first gear and rack assembly 4222.

[0096] The output shaft of the first motor 411 drives the first worm gear, thereby driving the first worm gear to rotate coaxially with the output shaft. The first worm wheel meshes with the first worm gear, and when the first worm gear rotates, it can drive the first worm wheel to rotate. The rotation axis of the first worm wheel is intersected with the rotation axis of the first worm gear.

[0097] The first worm gear meshes with the driving gear to drive the driving gear to rotate. The driven gear meshes with the driving gear to drive the driven gear to rotate when the driving gear rotates. Each output part 422 is connected to the driven gear and the corresponding blocking part 31, so that when the driven gear rotates, it drives the two blocking parts 31 to move synchronously.

[0098] The output section 422 includes a second worm gear 4221 and a first gear and rack assembly 4222. The driven gear meshes with the second worm gear, thereby driving the second worm gear to rotate. The second worm gear meshes with both second worms, thereby driving the two second worms to rotate in opposite directions. The rotation axis of the second worm is parallel to the rotation axis of the first worm.

[0099] Two first gear and rack assemblies 4222 are also provided, each corresponding to a second worm. The first gear of the first gear and rack assembly 4222 is sleeved on the outside of the second worm and rotates coaxially with the second worm, that is, the first gear and the second worm have the same axis of rotation. The first gear meshes with the first rack, thereby driving the first rack to move. The first rack is connected to the shielding part 31 so that the shielding part 31 can rotate around the circumference F2 of the cleaning member 21.

[0100] Understandably, when the cleaning component 21 is configured as a roller brush or a conveyor belt wipe, and the shielding part 31 moves in a circular motion along the circumferential direction F2 of the cleaning component 21, the movement trajectory of the shielding part 31 is arc-shaped. To ensure the stable movement of the shielding part 31, the first rack is flexibly designed. Therefore, when the first rack moves, its shape can change along the outer peripheral contour of the cleaning component 21 to adapt to the cleaning component 21, thereby improving the stability of the shielding part 31's movement.

[0101] Based on the structure of the shielding part 31 described above, the movement of the shielding part 31 will be explained in detail. Please refer to [link / reference needed]. Figure 2 and Figure 7 Continuing from the previous statement, "The shielding part 31 includes a first baffle 312 and a second baffle 313 stacked together, and the second baffle 313 is connected by a first rack and pinion drive."

[0102] When the output shaft of the first motor 411 rotates forward, it drives the second baffle 313 to rotate around the cleaning member 21 in the circumferential direction F2 via the first worm gear 4211, the gear transmission structure 4212, the second worm gear 4221, and the first gear and rack assembly 4222. At this time, the second baffle 313 is movably extended relative to the first baffle 312. When the second baffle 313 is moved to the maximum extended position, the second abutting part 45 abuts against one of the first abutting parts 44.

[0103] If the two opposing sides of the two second baffles 313 are not yet aligned at this point, the first rack continues to drive the second baffles 313 to move. Since the first abutting part 44 and the second abutting part 45 are in contact, the second baffles 313 drive the first baffle 312 to move synchronously relative to the support part 1. The first baffles 312 and the second baffles 313 can move synchronously to the blocking position, thereby allowing the opposing sides of the two second baffles 313 to align and isolate the cleaning component 21 from the path surface.

[0104] When the output shaft of the first motor 411 reverses, it drives the second baffle 313 to rotate around the cleaning component 21 in the circumferential direction F2 via the first worm gear 4211, the gear transmission structure 4212, the second worm gear 4221, and the first gear and rack assembly 4222. At this time, the second baffle 313 moves closer to the first baffle 312, and the opposite sides of the two second baffles 313 move apart.

[0105] When the second baffle 313 is fully retracted into the receiving cavity 3121, the second abutting part 45 abuts against the other first abutting part 44. As the first rack continues to drive the second baffle 313 to move, since the second abutting part 45 abuts against the other first abutting part 44, the second baffle 313 drives the first baffle 312 to move synchronously in opposite directions. The first baffle 312 and the second baffle 313 can move synchronously to the open position, exposing the cleaning component 21 and making contact with the path surface.

[0106] In another embodiment, please refer to Figure 10 The output unit 422 includes a second gear and rack assembly 4223, which includes a second gear and a second rack that mesh with each other. The second gear is driven to the input unit 421. The second rack is arranged along the radial direction F3 of the cleaning member 21 and is driven to the shielding part 31.

[0107] It should be noted that there are two second racks, which are located on both sides of the second gear and mesh with it. The input unit 421 drives the second gear to rotate, and the second gear drives the two second racks to move synchronously in opposite directions, so that the two second racks can drive the two blocking parts 31 to move relative to each other.

[0108] Based on the structure of this embodiment, the movement of the blocking drive assembly 4 will be described in detail below. The blocking drive assembly 4 includes a first motor 411, a first worm gear 4211, a gear transmission structure 4212, and a second gear and rack assembly 4223.

[0109] The output shaft of the first motor 411 drives the first worm gear, thereby driving the first worm gear to rotate coaxially with the output shaft. The first worm wheel meshes with the first worm gear, and when the first worm gear rotates, it can drive the first worm wheel to rotate. The rotation axis of the first worm wheel is intersected with the rotation axis of the first worm gear.

[0110] The first worm gear meshes with the driving gear to drive the driving gear to rotate. The driven gear meshes with the driving gear to drive the driven gear to rotate when the driving gear rotates. Each output part 422 is connected to the driven gear and the corresponding blocking part 31, so that when the driven gear rotates, it drives the two blocking parts 31 to move synchronously.

[0111] The output unit 422 includes a second gear and rack assembly 4223. The driven wheel meshes with the second gear, thereby driving the second gear to rotate. The second gear meshes with two second racks, thereby driving the two second racks to move synchronously. The two second racks move in opposite directions, thereby driving the two blocking parts 31 to move relative to each other, and each blocking part 31 moves around the circumference F2 of the cleaning member 21.

[0112] To ensure the stability of the second rack's movement, in this embodiment, the shielding drive assembly 4 further includes a second guide structure 43, which includes two guide portions 431. The two guide portions 431 are respectively disposed corresponding to the two second racks and are located on opposite sides of the two second racks. Each guide portion 431 includes a plurality of guide pulleys spaced apart radially F3 along the cleaning member 21, and the guide pulleys are in contact with the sides of the second racks.

[0113] In this embodiment, multiple guide pulleys are provided on the side of the second rack, and the multiple guide pulleys are arranged at intervals along the radial direction F3 of the cleaning component 21, so as to play a guiding role in the movement of the second rack.

[0114] Meanwhile, guide portions 431 are respectively provided on the opposite sides of the two second racks. The two guide portions 431 limit the second gear rack assembly 4223 in the axial direction F1 of the cleaning member 21, thereby preventing the second gear from pushing the second rack to deviate in the axial direction F1 of the cleaning member 21 during the meshing process with the second rack, thus ensuring that the second rack moves according to the predetermined motion trajectory.

[0115] Following on from the previous statement, "a limiting part 321 and a mating part 322 are correspondingly provided between the first baffle 312 and the support part 1." When the blocking part 31 is in the blocking position, the limiting part 321 and the mating part 322 engage in a limiting fit to limit and fix the first baffle 312 and the support part 1, thereby preventing the first baffle 312 from moving excessively.

[0116] To further improve the motion accuracy of the blocking part 31, in one embodiment, please refer to Figure 3 The cleaning module 100 also includes a position detection component 5 and a control component (not shown in the figure). The position detection component 5 is disposed on the support part 1 and is used to detect the position of the blocking part 31. The control component is electrically connected to the position detection component 5 and the blocking drive component 4, so as to control the blocking drive component 4 to stop driving when the position detection component 5 detects that the blocking part 31 is in the blocking position.

[0117] By setting up a position detection component 5 and a control component, when the position detection component 5 detects that the blocking part 31 is in a blocking position, the control component controls the blocking drive component 4 to stop driving. This can further improve the movement accuracy of the blocking part 31.

[0118] This utility model also provides a cleaning device 1000. The cleaning device 1000 can be a vacuum cleaner, a robotic vacuum cleaner, or a combined vacuum and mop, etc. Please refer to [link / reference]. Figure 11 The cleaning device 1000 includes the cleaning module 100 in the above embodiments, and has all the technical features of the cleaning module 100 and the technical effects brought about by all the technical features. Here, the specific structure of the cleaning module 100 will not be described.

[0119] Please see Figure 11 The cleaning device 1000 may also include a cleaning body 200, and a cleaning module 100 may be disposed at the bottom of the cleaning body 200. The cleaning body 200 is equipped with a control circuit board or control switch to control the cleaning module 100 to perform cleaning operations. A shielding component 3 is provided on the cleaning module 100 of the cleaning device 1000.

[0120] When the cleaning device 1000 moves forward, the cleaning component 21 of the cleaning module 100 needs to clean the path surface. The two blocking parts 31 of the blocking component 3 move relative to each other to the open position. At this time, the two blocking parts 31 separate, so that the cleaning component 21 is exposed and in contact with the path surface, and the cleaning component 21 can clean the path surface smoothly.

[0121] When the surface that the cleaning device 1000 passes through does not require cleaning, the two blocking parts 31 of the blocking assembly 3 move relative to each other to the blocking position. At this time, the two blocking parts 31 are connected and isolate the cleaning component 21 from the path surface, so that the cleaning component 21 will not come into contact with the path surface, thereby avoiding the sewage from the cleaning component 21 from contaminating the path surface.

[0122] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
