Description

[0001] This application is a divisional application of the patent application filed on April 3, 2025, with application number 2025206287102 and invention title "A Cleaning Component and Cleaning Equipment". Technical Field

[0002] This utility model relates to cleaning equipment, specifically to a cleaning component and a cleaning device. Background Technology

[0003] Existing cleaning equipment, such as robotic vacuum cleaners, robotic floor scrubbers, and robotic vacuum and mop combos, is typically equipped with cleaning components. These components contact the surfaces to be cleaned to perform the corresponding cleaning tasks. However, the cleaning components (such as mops and cleaning cloths) of traditional cleaning equipment are prone to horizontal displacement during the cleaning process, affecting cleaning efficiency and effectiveness, and significantly reducing the user experience. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a cleaning component and a cleaning device to improve the cleaning efficiency and cleaning effect of the cleaning component.

[0005] To achieve the above-mentioned objectives and other related objectives, the first aspect of this utility model provides a cleaning component, including: a first connector, a second connector, and a cleaning mechanism.

[0006] The first connector is used for detachable connection to the bottom of the cleaning equipment body; the second connector is slidably installed on the first connector; the cleaning mechanism is movably installed on the second connector; wherein, the second connector includes a cavity, the cavity being recessed on one side facing the cleaning mechanism, the cavity having a protruding structure inside, the protruding structure connecting one side wall of the cavity along its length direction to the bottom wall of the cavity, the bottom wall of the cavity having two first through slots, along the width direction of the cavity, the two first through slots being respectively located on both sides of the protruding structure, and both extending along the length direction of the cavity; along the height direction of the second connector, the first... The two connectors have a shielding part on the side of the first through groove away from the cleaning mechanism. The cleaning mechanism has two sets of connecting ends on the side facing the first connector. Each set of connecting ends includes two extensions. One end of the extension is connected to the side of the cleaning mechanism facing the first connector. One extension corresponds to one first through groove. The extension is slidably installed in the first through groove and extends at least partially into the cavity. The shielding part is used to shield the extension. The shielding part has a second groove on the side facing the extension. The extension has a protrusion on the side facing the shielding part that matches the second groove.

[0007] In one embodiment of the present invention, a second guide component is provided between the first connector and the second connector to guide the second connector to slide along the first connector.

[0008] In one embodiment of the present invention, the second guide component includes a sliding cavity and a second sliding part, the sliding cavity being disposed on the first connector and the second sliding part being disposed on the second connector.

[0009] In one embodiment of this utility model, the cleaning assembly includes a cleaning component and a support assembly. The support assembly includes a support body and a roller structure. The support body includes a first support and a second support. The roller structure includes a first roller and a second roller. The first roller is rotatably mounted on the outside of the first support, and the second roller is rotatably mounted on the outside of the second support. The second roller is arranged parallel to the first roller. The cleaning component is wound around and covers the outer peripheral surfaces of the first roller and the second roller. When the first roller and the second roller rotate, they drive the cleaning component to rotate.

[0010] In one embodiment of the present invention, at least a portion of the outer peripheral surfaces of the first roller and the second roller that come into contact with the cleaning component are made of rubber.

[0011] In one embodiment of the present invention, the cleaning component includes a pulling member disposed between a first support and a second support, and the pulling member has a pulling force that brings the first support and the second support closer to each other.

[0012] In one embodiment of the present invention, the cleaning component includes an external support component, which is slidably disposed between the first bracket and the second bracket. When the external support component slides between the first bracket and the second bracket, it pushes the first bracket and the second bracket apart to both sides.

[0013] In one embodiment of the present invention, the external support assembly has at least a first position and a second position on the sliding path. When the external support assembly is in the first position, the external support assembly causes the first bracket and the second bracket to have a first gap that tensions the cleaning component. When the external support assembly is in the second position, the traction force of the pulling member causes the first bracket and the second bracket to have a second gap that relaxes the cleaning component.

[0014] In one embodiment of the present invention, a first guide component is provided between the first support and the second support, the first guide component being used to guide the first support and the second support to slide along the direction of the tensile force.

[0015] The second aspect of this utility model provides a cleaning device, including the cleaning components described above.

[0016] The beneficial effects of this application are as follows: When the cleaning mechanism is in the mopping position, the ground reaction force will cause the cleaning component to tend to move upward. At this time, the blocking part can effectively limit the maximum upward movement of the cleaning component by contacting and cooperating with the extension part. This limiting mechanism can ensure that the cleaning component and the ground maintain a stable contact pressure, thereby ensuring the consistency of the cleaning effect. Furthermore, when the cleaning mechanism is in the mopping position, the extension part moves upward under the push of the ground reaction force, and the protrusion part will be correspondingly locked into the second groove. This design can limit the movement of the extension part along the outward expansion and inward contraction direction of the cleaning component, thereby improving the horizontal installation stability of the cleaning component relative to the machine body when in the mopping position. Therefore, it can reduce the probability of horizontal displacement of the cleaning component during the cleaning operation, further improving the cleaning effect and cleaning efficiency of the cleaning component.

Unless otherwise defined, all technical and scientific terms used in this invention, as well as the prior art known to those skilled in the art and the description of this invention, may be implemented using any prior art methods, equipment, and materials similar to or equivalent to those in the embodiments of this invention.

[0188] It should be noted that the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0189] Please see Figures 1 to 88 This utility model provides a cleaning component 100 and a cleaning device 1000. The cleaning component 100, through the coordinated design of the bracket component 120, the tensioning component 130 and the external support component 140, can realize the rapid switching between the cleaning component 110 and the slack state, thereby improving the replacement efficiency of the cleaning component 110 and the cleaning efficiency of the cleaning device 1000.

[0190] The cleaning device 1000 provided in the embodiments of this utility model can be a self-moving cleaning robot or a handheld floor scrubber. The self-moving cleaning robot can be a mopping robot or a sweeping and mopping robot, etc.

[0191] In the following embodiments, the cleaning device 1000 is a self-moving cleaning robot, and some of its components are described as an example. However, those skilled in the art will understand that other robots that include the cleaning component 100 of this utility model can also have the beneficial effects brought by the cleaning component 100 of this utility model.

[0192] Please see Figure 1 The cleaning equipment 1000 has a body 200, the interior of which can accommodate various components of the cleaning equipment 1000. The body 200 can be any shape, such as cylindrical, elliptical, or D-shaped.

[0193] The cleaning equipment 1000 also includes a walking system conventionally provided on existing cleaning equipment 1000, used to drive the machine body 200 to move independently, thereby achieving a self-moving walking function on the surface to be cleaned. The walking system includes at least a driver and drive wheels 240, which rotate under the action of the driver. There are generally two drive wheels 240, symmetrically arranged at the bottom of the machine body 200. The specific structure of the walking system and the connection structure between the walking system and the machine body 200 can be referred to the relevant structural descriptions in existing cleaning equipment 1000, and will not be repeated here.

[0194] To perform its cleaning function, the cleaning device 1000 includes at least a cleaning component 100. The cleaning component 100 is detachably connected to the main body 200, and the detachable connection method can be a snap-fit ​​connection, a bolt-fit connection, or the like. The cleaning component 100 can be configured for dry mopping or wet mopping. Optionally, in this embodiment, the cleaning component 100 is configured for wet mopping.

[0195] Alternatively, in one embodiment, please refer to Figures 1 to 3 The cleaning device 1000 may also include a side brush 210 and a roller brush 220, which are located at the bottom of the body 200. Along the direction of travel of the body 200... Figure 2 As shown by arrow W1, both the side brush 210 and the roller brush 220 are located in front of the cleaning assembly 100. The side brush 210 can be positioned at the edge of the body 200 and can rotate via a rotating mechanism, such as a combination of a motor and a reducer. When the side brush 210 rotates, it gathers debris from the edge of the body 200 towards the inside of the body 200, thereby increasing the cleaning range of the cleaning equipment 1000. The side brush 210 can be a rubber strip or a bristle brush, as long as it can clean the floor; there are no restrictions here. The roller brush 220 is rotatably mounted in a roller brush cavity at the bottom of the body 200. During its rotation, the roller brush 220 sweeps away debris from the floor. The number of roller brushes 220 can be set according to specific requirements; this embodiment does not limit the number.

[0196] Along the traveling direction of the machine body 200, the side brush 210 and the roller brush 220 are positioned in front of the cleaning component 100. This facilitates the cleaning operation of the cleaning equipment 1000, which involves dry sweeping followed by wet mopping, and also facilitates the layout of the internal space of the machine body 200.

[0197] In addition, the cleaning equipment 1000 may also include a sensing system and a control system. The sensing system and the control system are electrically connected. The sensing system includes an LDS located on top of the fuselage 200, a buffer and vision sensor located at the front of the fuselage 200, and an edge sensor located on the front side wall of the fuselage 200. Among them, the LDS, buffer, and edge sensor can all measure or sense distance to obtain the distance between the edge of the fuselage 200 and obstacles. The control system controls the cleaning equipment 1000 to perform corresponding actions based on this distance. For example, it controls the cleaning equipment 1000 to perform obstacle avoidance, edge cleaning, and return to the base station.

[0198] The cleaning component 100 can be implemented in various ways. Optionally, in this embodiment, please refer to... Figures 3 to 12 The cleaning component 100 includes: a cleaning component 110, a support component 120, a tension component 130, and an external support component 140.

[0199] The cleaning component 110 can be made of materials such as fiber cloth, sponge, or rubber, and is wound around the support assembly 120. The winding shape of the cleaning component 110 on the support assembly 120 can be planar, ring-shaped, or other shapes. For an example, please refer to [reference needed]. Figure 4 and with Figure 7 In this embodiment, the cleaning component 110 is wrapped around the outer periphery of the support assembly 120 in a shape similar to a circular racetrack to form a track-like structure.

[0200] Please see Figure 9 , Figure 10 and Figure 13The support assembly 120 includes a support body, which includes a first support 121 and a second support 122. A cleaning member 110 is wound around and supported by the first and second supports 121 and 122. A pulling member 130 is disposed between the first and second supports 121 and 122. The pulling member 130 has a pulling force that brings the first and second supports 121 and 122 closer together. Specifically, when the first and second supports 121 and 122 separate, the pulling member 130 is stretched, increasing its pulling force to provide a restoring pulling force that brings the first and second supports 121 and 122 closer together. When the first and second supports 121 and 122 approach each other, the pulling member 130 also has a pulling force, which is used to keep the first and second supports 121 and 122 in close contact and prevent them from separating. The pulling element 130 can be a tension spring, an elastic band, or a combination of rope and pulley structure, as long as it can generate a pulling force that brings the first support 121 and the second support 122 closer to each other.

[0201] In other embodiments, the pulling member 130 may only have a pulling force that brings the first support 121 and the second support 122 closer together when the first support 121 and the second support 122 are separated from each other, and the pulling member 130 does not deform and does not generate a pulling force when the first support 121 and the second support 122 are in contact with each other.

[0202] Under the condition of meeting the tension requirements between the first support 121 and the second support 122, one, two, or more tensioning members 130 may be provided. Optionally, in order to achieve uniformity of tension force between the first support 121 and the second support 122 in the length direction, in this embodiment, please refer to... Figure 9 and Figure 10 There are two tension members 130, which are respectively located near the two ends of the support assembly 120 along its length.

[0203] Please see Figure 13 , Figure 14 and Figure 17The outer support assembly 140 is slidably disposed between the first bracket 121 and the second bracket 122. When the outer support assembly 140 slides between the first bracket 121 and the second bracket 122, it expands the first bracket 121 and the second bracket 122 to both sides. The outer support assembly 140 can be a single integral piece, which is slidably inserted between the first bracket 121 and the second bracket 122, thereby expanding the first bracket 121 and the second bracket 122 to both sides. The outer support assembly 140 can also be multiple parts, with only some parts slidably inserted between the first bracket 121 and the second bracket 122 to achieve relative separation between the first bracket 121 and the second bracket 122. The sliding insertion path of the outer support assembly 140 can be a straight line, a curve, or other specific shape, and the outer support assembly 140 has at least a first position and a second position on the sliding path.

[0204] like Figure 15 As shown, when the external support assembly 140 is in the first position, the external support assembly 140 provides a first gap between the first bracket 121 and the second bracket 122, which tensions the cleaning member 110. Figure 17 As shown, when the external support assembly 140 is in the second position, the traction force of the pulling member 130 causes the first bracket 121 and the second bracket 122 to have a second gap that allows the cleaning member 110 to relax. The specific size of the first gap and the second gap is not limited, and needs to be determined according to the size of the cleaning member 110 during the actual design and production process.

[0205] An external support assembly 140 and a tensioning member 130 are provided between the first support 121 and the second support 122, with the tensioning member 130 having a pulling force that brings the first support 121 and the second support 122 closer together. The external support assembly 140 slides between a first position and a second position. With this configuration, when the cleaning component 110 needs to be tensioned, sliding the external support assembly 140 to the first position creates a first gap between the first support 121 and the second support 122, thereby achieving tension of the cleaning component 110. In the tensioned state, the cleaning component 110 can better conform to the surface to be cleaned, improving the cleaning effect. When the cleaning component needs to be switched to a relaxed state, sliding the external support assembly 140 to the second position causes the first support 121 and the second support 122 to move closer together under the pulling force, thus creating a second gap between the first support 121 and the second support 122, thereby achieving relaxation of the cleaning component 110. In the relaxed state, it is more convenient to store and replace the cleaning component 110. It should be noted that "closer to each other" here refers to the first support 121 and the second support 122 being able to fit together, or having other distances smaller than the first distance. That is, the distance between the first support 121 and the second support 122 is greater than or equal to zero and less than the first distance. The following related content is explained in the same way. Therefore, the cleaning component 100, through the synergistic action of the outer support component 140 and the tensioning component 130, can achieve rapid switching between the tensioned and relaxed states of the cleaning component 110, thereby simplifying the replacement operation steps of the cleaning component 100, shortening the replacement operation time, and thus improving the replacement efficiency of the cleaning component 100 and the cleaning efficiency of the cleaning equipment 1000. Furthermore, in the tensioned state, the cleaning component 100 of this utility model achieves rigid tension through the outer support component 140, which has higher tension stability than tension achieved through elastic components such as compression springs, and can prevent local torsion or misalignment of the cleaning component 110 due to inconsistent tension force.

[0206] To improve the sliding accuracy between the first support 121 and the second support 122 and reduce jamming during sliding, optionally, please refer to Figure 14 , Figure 18 and Figure 20In one embodiment of this utility model, a first guide component 150 is provided between the first support 121 and the second support 122. The first guide component 150 is used to guide the first support 121 and the second support 122 to slide in the direction of the tension force. The specific structure of the first guide component 150 can be varied, such as a guide rail and slider structure, a groove and slider structure, a guide rod and guide sleeve structure, or other structures with guiding functions. By providing the first guide component 150, the first guide component 150 can ensure that the first support 121 and the second support 122 slide in a predetermined direction, reducing the probability of mutual offset or wobbling during the sliding process. This improves the sliding accuracy between the first support 121 and the second support 122, reduces jamming during the sliding process, and enhances the smoothness of the sliding between the first support 121 and the second support 122. Simultaneously, the first guide component 150 can also provide additional support for the first support 121 and the second support 122, which helps to enhance the overall rigidity and stability of the support assembly 120.

[0207] Optionally, in one embodiment of this utility model, please refer to Figure 14 , Figure 18 and Figure 20 The first guide assembly 150 includes a plug-in portion 151 and a slot 152, which are respectively disposed on opposite sides of the first bracket 121 and the second bracket 122. During the process of the first bracket 121 and the second bracket 122 approaching or separating from each other, the plug-in portion 151 can be slidably inserted into the slot 152. In this embodiment, the plug-in portion 151 is disposed on the side of the second bracket 122 facing the first bracket 121, and the slot 152 is disposed on the side of the first bracket 121 facing the second bracket 122.

[0208] In another embodiment, the insertion portion 151 may be disposed on the side of the first bracket 121 facing the second bracket 122, and the slot 152 may be disposed on the side of the second bracket 122 facing the first bracket 121. In other embodiments, the insertion portion 151 may be partially disposed on the first bracket 121 and partially disposed on the second bracket 122. Correspondingly, the slot 152 is partially disposed on the second bracket 122 to cooperate with the portion of the insertion portion 151 disposed on the first bracket 121, and the other part of the slot 152 is disposed on the first bracket 121 to cooperate with the portion of the insertion portion 151 disposed on the second bracket 122.

[0209] The connector 151 may be along the length of the bracket assembly 120 (e.g., Figure 15 The structure can be an elongated block (as shown on the X-axis) or a series of protrusions spaced apart along the length of the support assembly 120. The slot 152 matches the shape of the insertion part 151 for insertion.

[0210] It should be noted that, due to the different mating structures of the insertion part 151 and the slot 152, when the insertion part 151 and the slot 152 are inserted, the first bracket 121 and the second bracket 122 can be aligned in the height direction of the bracket assembly 120 (e.g., ...). Figure 16 The mutual limiting of the bracket assembly 120 (as shown by the Z-axis) forms a guiding effect, or the mutual limiting of the bracket assembly 120 in the length direction forms a guiding effect, or the bracket assembly 120 in both the height and length directions forms a guiding effect.

[0211] Specifically, in this embodiment, please refer to Figure 15 , Figure 17 , Figure 18 and Figure 20 The insertion part 151 is an elongated block structure, extending along the length direction of the second bracket 122 and substantially covering its entire length. Correspondingly, the slot 152 extends along the length direction of the first bracket 121 and substantially covers its entire length. When the insertion part 151 engages with the slot 152, the upper and lower sides of the insertion part 151 respectively cooperate with the upper and lower sides of the slot 152 along the height direction of the bracket assembly 120 to form a contact relationship during engagement, thereby providing a guiding effect along the height direction of the bracket assembly 120 between the first bracket 121 and the second bracket 122. It should be noted that the aforementioned "upper and lower sides," i.e., the slot 152 or the insertion part 151 along the height direction of the second bracket 122, are... Figure 16 The two sides along the Z-axis.

[0212] By providing the insertion part 151 and the slot 152, the cooperation between the insertion part 151 and the slot 152 allows for smoother sliding between the first bracket 121 and the second bracket 122, thus serving as a sliding guide. Furthermore, the simple and easy-to-implement structural design of the insertion part 151 and the slot 152 helps reduce manufacturing costs.

[0213] Please see Figure 14 , Figure 18 , Figure 20 and Figure 21In one embodiment of this utility model, the first guide assembly 150 further includes a guide groove 153 and a guide rod 154. The guide groove 153 and the guide rod 154 are respectively disposed on the first bracket 121 and the second bracket 122. The guide rod 154 is inserted into the guide groove 153 and slides along the guide groove 153 during the process of the first bracket 121 and the second bracket 122 approaching or separating from each other. The guide groove 153 is an elongated groove structure extending along the sliding direction of the first bracket 121 and the second bracket 122. The cooperation between the guide groove 153 and the guide rod 154 defines the maximum distance between the first bracket 121 and the second bracket 122, which is greater than or equal to a first distance.

[0214] The number of guide grooves 153 and guide rods 154 is unlimited; one or more can be used. One guide groove 153 can correspond to one guide rod 154, or one guide groove 153 can correspond to multiple guide rods 154. Optionally, please refer to... Figure 13 In this embodiment, along the length of the bracket assembly 120, two guide grooves 153 and two guide rods 154 are provided at intervals, and one guide rod 154 is inserted into each guide groove 153.

[0215] Specifically, please refer to Figure 18 , Figure 20 and Figure 21 In this embodiment, two guide grooves 153 are disposed on the second bracket 122 and located on the insertion portion 151. Two guide rods 154 are disposed on the first bracket 121 and connected to the groove wall of the slot 152. In another embodiment, two guide grooves 153 may be disposed on the first bracket 121 and two guide rods 154 may be disposed on the second bracket 122. In other embodiments, two guide grooves 153 may be respectively disposed on the first bracket 121 and the second bracket 122, and two guide rods 154 may be respectively disposed on the first bracket 121 and the second bracket 122.

[0216] By setting the guide groove 153 and the guide rod 154, the guide rod 154 slides within the guide groove 153. On the one hand, it can limit the maximum separation distance (greater than or equal to the first gap) and the minimum approach distance (i.e., the second gap) between the first bracket 121 and the second bracket 122, ensuring the consistency of the tension of the bracket assembly 120 on the cleaning component 110. Simultaneously, it can also limit the movement distance of the insertion part 151 within the slot 152, thereby ensuring that at least a portion of the insertion part 151 is always located within the slot 152. That is, when the first bracket 121 and the second bracket 122 are at their maximum separation distance, at least a portion of the insertion part 151 is always located within the slot 152, which helps improve the smoothness of sliding between the first bracket 121 and the second bracket 122. On the other hand, the guide groove 153 and the guide rod 154, working together, can also guide the mutual movement of the first bracket 121 and the second bracket 122, further improving the guiding effect between the first bracket 121 and the second bracket 122 and ensuring sliding accuracy.

[0217] Considering the repeatability of the position when the first bracket 121 and the second bracket 122 are in contact with each other, optionally, please refer to Figure 14 and Figure 17 In one embodiment of this utility model, the side of the first support 121 facing the second support 122 includes a first mating portion 1211, and the side of the second support 122 facing the first support 121 includes a second mating portion 1221. When the first support 121 and the second support 122 are fitted together, the first mating portion 1211 and the second mating portion 1221 abut against each other to form a mating seam 123, which includes a bent section 1231. The mating seam 123 can be a continuous mating seam structure distributed along the length direction of the support assembly 120, or it can be multiple discontinuously distributed mating seam structures. Optionally, in this embodiment, the mating seam 123 is a continuous mating seam structure distributed along the length direction of the support assembly 120, and the length of the mating seam 123 approximately covers the entire length of the support assembly 120.

[0218] The bending segment 1231 can be a variety of bending structures, such as an arc bend, a V-shaped bend, or a wavy bend. One bending segment 1231 or multiple bending segments 1231 can be provided on the butt joint 123. Optionally, please refer to... Figure 14 In this embodiment, the butt joint 123 is provided with multiple approximately trapezoidal bent segments 1231. This arrangement facilitates the docking of the first and second supports and creates a limiting position between them. Compared to a straight seam butt joint structure, this structure has higher docking stability.

[0219] Specifically, in this embodiment, please refer to Figure 19 and Figure 20The insertion portion 151 has a boss structure formed on the side opposite to the slot 152. The boss structure includes multiple first protrusions 1511 protruding towards the slot 152 and multiple first recesses 1512 recessed on the side opposite to the slot 152. The slot 152 has multiple second recesses 1522 and multiple second protrusions 1521 correspondingly provided on the wall edge on the side opposite to the insertion portion 151. The second recesses 1522 correspond to and match the first protrusions 1511, and the second protrusions 1521 correspond to and match the first recesses 1512. When the first mating portion 1211 and the second mating portion 1221 are mated together, the first recesses 1512 and the second protrusions 1521 are aligned, and the first protrusions 1511 and the second recesses 1522 are aligned, thereby forming a mating seam 123 with a bent section 1231.

[0220] Because the joint 123 includes a bent section 1231, when the first mating portion 1211 and the second mating portion 1221 are mated, they can be connected in both the length and width directions of the bracket assembly 120 (e.g., ...). Figure 15 Positioning is achieved simultaneously on the Y-axis (as shown in the middle). This design ensures that the first bracket 121 and the second bracket 122 can be accurately aligned in a predetermined direction, reducing the possibility of misalignment or shaking of the first bracket 121 and the second bracket 122 during alignment, thereby improving the alignment accuracy when the first bracket 121 and the second bracket 122 are in contact with each other, and ensuring the repeatability accuracy of their alignment.

[0221] Although the tension member 130 can have various structures, considering the manufacturing cost and structural complexity of the tension member 130, optionally, in one embodiment of this utility model, please refer to... Figure 9 and Figure 10 The pulling component 130 is an elastic element, with its two ends connected to the first support 121 and the second support 122 respectively. The elastic force generated by the elastic element forms a pulling force. The elastic element can be any elastic element that can generate a pulling force when the first support 121 and the second support 122 approach each other, such as a tension spring, elastic band, or rubber rope. By making the pulling component 130 an elastic element, the elastic force of the elastic element automatically pulls the first support 121 and the second support 122 back to their approaching state, realizing automatic approach between the first support 121 and the second support 122. This reduces manual intervention and simplifies operation. At the same time, the presence of the elastic element also ensures that the first support 121 and the second support 122 maintain a certain elastic connection when they separate, preventing structural loosening or loss of control and improving the overall stability of the support assembly 120. In addition, the structure of the elastic element is relatively simple and does not require additional components, so installation is convenient and the procurement and manufacturing costs are correspondingly reduced.

[0222] With the tension member 130 being an elastic member, optionally, in one embodiment of this utility model, please refer to... Figure 9, Figure 10 , Figure 11 and Figure 70 The elastic element is a tension spring, with its two ends connected to the first bracket 121 and the second bracket 122, respectively. The spring force generated by the tension spring forms a pulling force. The position of the tension spring on the first bracket 121 and the second bracket 122 is not limited. For example, the tension spring can be placed in the area of ​​the first bracket 121 and the second bracket 122 where the insertion part 151 and the slot 152 are not provided, or it can be placed between the insertion part 151 and the slot 152. The extension and contraction direction of the tension spring is consistent with the sliding direction of the first bracket 121 and the second bracket 122. It should be noted that when the first bracket 121 and the second bracket 122 are in the contact position, the tension spring still needs to have a certain spring force to generate a certain pulling force on the first bracket 121 and the second bracket 122 at the contact position. Since tension springs are usually standard parts, they are easy to purchase, and there are many specifications and models to choose from, which is beneficial for design selection. Furthermore, tension springs are relatively easy to install, occupy little space, and are beneficial for compact structural design.

[0223] Please see Figure 21 , Figure 22 and Figure 25 In one embodiment of this utility model, a mounting cavity 124 is provided on the first bracket 121 and the second bracket 122, and the tension spring is disposed within the mounting cavity 124. The mounting cavity 124 may be partially disposed on the insertion portion 151 of the first bracket 121 and partially disposed within the slot 152 of the second bracket 122. The shape of the mounting cavity 124 may be a cuboid, cylinder, or other shapes capable of accommodating the tension spring. In another embodiment, the mounting cavity 124 may be disposed only on the insertion portion 151 of the first bracket 121. In other embodiments, the mounting cavity 124 may be disposed only within the slot 152 of the second bracket 122. By providing the mounting cavity 124, a protective effect can be provided for the tension spring, reducing the probability of impurities or particles falling onto the tension spring and causing it to become stuck during extension and contraction.

[0224] Specifically, please refer to Figure 21 , Figure 22 and Figure 25In this embodiment, the first bracket 121 is provided with a first mounting cavity 1241, the opening of which faces the second bracket 122. The second bracket 122 is provided with a second mounting cavity 1242, the opening of which faces the first bracket 121. The first mounting cavity 1241 and the second mounting cavity 1242 are coaxially arranged, and the outer diameter of the second mounting cavity 1242 is less than or equal to the inner diameter of the first mounting cavity 1241, so that the second mounting cavity 1242 can be inserted into the first mounting cavity 1241. The first bracket 121 is provided with a first connecting post 131, which penetrates the first mounting cavity 1241 radially. The second bracket 122 is provided with a second connecting post 132, which penetrates the second mounting cavity 1242 radially. One end of the tension spring is located in the first mounting cavity 1241 and hooked to the first connecting post 131, while the other end of the tension spring is located in the second mounting cavity 1242 and hooked to the second connecting post 132.

[0225] An external support assembly 140 is disposed between the first support 121 and the second support 122 to allow for variation in the spacing between the first support 121 and the second support 122. The external support assembly 140 can have various structural forms; for options, please refer to [reference needed]. Figure 14 and Figure 17 In one embodiment of this utility model, the external support assembly 140 includes a base 141 and a first external support member 142. Along the length direction of the support assembly 120, one end of the first support 121 and one end of the second support 122 are both inserted into the base 141. There are various insertion methods. For example, the ends of the first support 121 and the second support 122 may be provided with columnar protrusions, and the base 141 may be provided with corresponding insertion holes, allowing the columnar protrusions to be inserted into the insertion holes to achieve mutual insertion. Alternatively, the ends of the first support 121 and the second support 122 may be provided with insertion holes, and the base 141 may be provided with corresponding columnar protrusions, allowing the columnar protrusions to be inserted into the insertion holes, thus also achieving mutual insertion.

[0226] The first external support member 142 is disposed at the end of the first bracket 121 and the second bracket 122 away from the seat 141, and can be slidably inserted between the first bracket 121 and the second bracket 122 to separate the first bracket 121 and the second bracket 122, thereby forming a first gap between the first bracket and the second bracket to tension the cleaning component. Simultaneously, the first connecting post 131 and the second connecting post 132 move away from each other, the tension spring is stretched, stores energy, and generates a rebound force. Correspondingly, when the first external support member 142 slides out from between the first bracket 121 and the second bracket 122, under the action of the rebound force of the tension spring, the first connecting post 131 and the second connecting post 132 move closer together, thereby causing the first bracket 121 and the second bracket 122 to move closer together, forming a second gap between the first bracket 121 and the second bracket 122 to relax the cleaning component 110. The first external support 142 can be a wedge-shaped structure, a cylindrical shape, a strip shape, or other structures. As long as the first external support 142 can slide between the first support 121 and the second support 122, it can gradually expand the first support 121 and the second support 122, so that the distance between the first support 121 and the second support 122 gradually increases to the second distance.

[0227] By configuring the external support assembly 140 into two parts, a base 141 and a first external support member 142, a separate design for the supporting and movable parts of the external support assembly 140 can be achieved. Since one end of the first bracket 121 and one end of the second bracket 122 are both inserted into the base 141, the base 141 needs to support the first bracket 121 and the second bracket 122, essentially functioning as the supporting part of the external support assembly 140. Therefore, the base 141 needs to have high support strength to provide stable support for the first bracket 121 and the second bracket 122. However, since the first external support member 142 needs to slide between the first bracket 121 and the second bracket 122 to allow them to separate or move closer together, the first external support member 142 functions as the movable part of the external support assembly 140. Therefore, the design of the first external support member 142 needs to consider sliding factors more carefully to ensure smooth sliding between the first bracket 121 and the second bracket 122. Therefore, the separate design of the fixed part and the movable part allows for flexible design of each part and is more conducive to the structural optimization of the external support assembly 140.

[0228] To further enhance the support strength of the external support assembly 140 for the first bracket 121 and the second bracket 122, optionally, please refer to Figure 7 , Figure 8In one embodiment of this utility model, the outer support assembly 140 further includes a housing 180 disposed above the cleaning component 110. The housing 180 covers the cleaning component 110, one end of the housing 180 is connected to the base 141, and the other end of the housing 180 extends along the length direction of the support assembly 120 and covers the entire length of the cleaning component 110. The housing 180 and the base 141 form a receiving cavity 190. An opening 191 is provided at the end of the receiving cavity 190 away from the base 141. The support assembly 120 and the cleaning component 110 are installed into the receiving cavity 190 from the opening 191, and one end of the support assembly 120 is sealed at the opening 191.

[0229] Specifically, in this embodiment, please refer to Figure 17 and Figure 18 The first support 121 includes a housing connecting portion 1212 and a support body 1213. The support body 1213 is disposed opposite to the second support 122 and is used to cooperate with the second support 122 to support the winding cleaning component 110. The end of the second support 122 away from the seat 141 is slidably connected to the housing connecting portion 1212. The housing connecting portion 1212 seals the opening 191 of the receiving cavity 190 and is detachably connected to the housing 180. The detachable connection method includes snap-fit ​​connection, bolt detachable connection, etc. In this embodiment, in order to facilitate the assembly and disassembly between the support assembly 120 and the housing 180, the housing connecting portion 1212 is snap-fit ​​connected to the housing 180.

[0230] In another embodiment, the second bracket 122 may be provided with a housing connecting portion 1212, and the first bracket 121 may be slidably connected to the housing connecting portion 1212. The housing connecting portion 1212 is connected to the housing 180, which also achieves the connection between the first bracket 121 and the second bracket 122 and the housing 180. In other embodiments, the first bracket 121 and the second bracket 122 may each be provided with a housing connecting portion 1212, and the first bracket 121 and the second bracket 122 may each be connected to the housing 180 through their own housing connecting portion 1212, thereby achieving the connection between the first bracket 121 and the second bracket 122 and the housing 180.

[0231] By providing the housing 180, the receiving cavity 190 formed by the housing 180 and the base 141 can protect the cleaning component 110, preventing it from being damaged by external forces during operation and extending its service life. Simultaneously, since both ends of the housing 180 are connected to the base 141 and the first support 121 and second support 122 respectively, the supporting strength of the first support 121 and second support 122 can be effectively improved, thus enhancing the stability of the cleaning assembly 100 during cleaning operations.

[0232] Because there is a pulling force between the first support 121 and the second support 122, the first outer support 142 will also be subjected to the compressive force of the first support 121 and the second support 122 when it slides between them. To prevent the first outer support 142 from sliding out from between the first support 121 and the second support 122 under the compressive force, and to ensure the stability of the support assembly 120 in supporting the cleaning component 110, optionally, in one embodiment of this utility model, please refer to... Figures 32 to 36 The housing 180 has a first engaging portion 1801 at the end away from the base 141. The first engaging portion 1801 can be a slot structure, a protrusion structure, etc. The first outer support member 142 includes an inner support arm 1422, a second engaging portion 1423, and an end cap 1424. Both the inner support arm 1422 and the second engaging portion 1423 are connected to the end cap 1424. The second engaging portion 1423 can be an elastic snap-fit ​​structure that matches the first engaging portion 1801. The end of the inner support arm 1422 away from the end cap 1424 can be slidably inserted between the first bracket 121 and the second bracket 122 to achieve mutual separation between the first bracket 121 and the second bracket 122. When the distance between the first bracket 121 and the second bracket 122 is a second distance, the first engaging portion 1801 and the second engaging portion 1423 can be engaged and fixed to each other.

[0233] By setting the first snap-fit ​​part 1801 and the second snap-fit ​​part 1802, when the first snap-fit ​​part 1801 and the second snap-fit ​​part 1423 are snapped together and fixed, not only can the relative fixed installation between the first external support 142 and the housing connection part 1212 be realized, but also the fixed connection between the bracket assembly 120 and the housing 180 can be realized.

[0234] Specifically, in this embodiment, please refer to Figures 35 to 39The housing connecting portion 1212 is provided with a through-hole snap-fit ​​groove 1215. A baffle 1216 is provided inside the snap-fit ​​groove 1215, dividing the snap-fit ​​groove 1215 into a first hole 12151 and a second hole 12152. The first hole 12151 communicates with the receiving cavity 190. The housing 180 is provided with a relief groove 1802 on the side opposite to the cleaning component 110. The first snap-fit ​​portion 1801 is disposed in the relief groove 1802, and the second hole 12152 communicates with the relief groove 1802. When the first outer support 142 is inserted into the snap-fit ​​groove 1215, the inner support arm 1422 is inserted from the first hole 12151 between the first bracket 121 and the second bracket 122 to separate the first bracket 121 and the second bracket 122. The second engaging portion 1423 is inserted into the clearance groove 1802 through the second hole 12152, engaging with the first engaging portion 1801 within the clearance groove 1802, thereby restricting the first outer support member 142 from moving outwards from the latching groove 1215. The end cap 1424 is correspondingly engaged into the latching groove 1215, and the baffle 1216 stops the end cap 1424 along the depth direction of the latching groove 1215, thereby restricting the end cap 1424 from further entering the interior of the latching groove 1215, thus limiting the insertion depth of the first outer support member 142 between the first bracket 121 and the second bracket 122.

[0235] Under the condition that the engagement requirements of the first engaging portion 1801 and the second engaging portion 1423 are met, the specific engagement structure of the first engaging portion 1801 and the second engaging portion 1423 is not limited. For example, it can be a hook-and-loop engagement structure, where the first engaging portion 1801 is configured as a hook, and the second engaging portion 1423 is configured as a corresponding groove or hole, achieving engagement by the hook engaging into the groove or hole. Alternatively, it can be a protrusion and groove mating structure, where the first engaging portion 1802 is configured as a protrusion, and the second engaging portion 1423 is configured as a corresponding groove, achieving engagement by the mating of the protrusion and the groove. Optionally, please participate... Figures 33 to 36 In this embodiment, the first latching portion 1801 includes a first latch 18011, and the second latching portion 1423 includes a second latch 14231. Along the sliding direction of the first outer support member 142, the opening of the first latch 18011 faces away from the latch groove 1215, and the opening of the second latch 14231 faces towards the side close to the latch groove 1215. The end cap 1424 is movable within the latch groove 1215 along the direction in which the first bracket 121 and the second bracket 122 move relative to each other (e.g., ...). Figure 35(As shown in the W3 direction) Sliding. In this sliding direction, the end cap 1424 has a first mounting position and a second mounting position within the latching groove 1215. When the end cap 1424 is in the first mounting position, the first latch 18011 and the second latch 14231 disengage from each other in the direction in which the first bracket 121 and the second bracket 122 move relative to each other. At this time, the first outer support member 142 can move freely in the insertion direction. When the end cap 1424 is in the second mounting position, the first latch 18011 and the second latch 14231 engage with each other, thereby restricting the movement of the first outer support member 142 towards the outside of the latching groove 1215. At the same time, the baffle 1216 in the latching groove 1215 restricts the movement of the end cap 1424 towards the inside of the latching groove 1215, thereby limiting the movement of the first outer support member 142 in the sliding direction.

[0236] In other embodiments, please refer to Figures 157 to 160 The first outer support member 142 is further provided with a fifth latch 14203. Specifically, the fifth latch 14203 is provided on the inner support arm 1422 of the first outer support member 142. The housing connecting part 1212 is also provided with a fourth latch 12122 that cooperates with the fifth latch 14203 near the first hole 12151. The engagement direction between the fifth latch 14203 and the fourth latch 12122 is consistent with the sliding direction of the end cover 1424 in the latch groove 1215. When the end cover 1424 is in the first installation position, the fifth latch 14203 and the fourth latch 12122 are disengaged. When the end cap 1424 is in the second installation position, the fifth buckle 14203 and the fourth buckle 12122 engage with each other, thereby limiting the probability of the inner support arm 1422 coming out of the first hole 12151, so as to further improve the stability of the first outer support member 142 in supporting the first bracket 121 and the second bracket 122.

[0237] Using the above-described snap-fit ​​structure, when the first outer support 142 needs to be fixed between the first bracket 121 and the second bracket 122, the end cap 1424 in the snap-fit ​​groove 1215 is slid from the first installation position to the second installation position, so that the first snap 18011 and the second snap 14231 are engaged with each other. Conversely, when the first outer support 142 needs to slide out from between the first bracket 121 and the second bracket 122, the end cap 1424 is slid in the opposite direction, so that the end cap 1424 is slid from the second installation position to the first installation position, so that the first snap 18011 and the second snap 14231 are disengaged from each other, that is, the engagement relationship between the first snap 18011 and the second snap 14231 is released, and the first outer support 142 can move freely along the sliding direction.

[0238] It should be noted that the number of first buckles 18011 and second buckles 14231 can be one or more, as long as the buckle strength requirements are met. Optionally, in this embodiment, the number of first buckles 18011 and second buckles 14231 are both two, with one first buckle 18011 corresponding to one second buckle 14231. This arrangement forms two engagement points when the first engagement portion 1801 and the second engagement portion 1423 engage with each other, thereby improving the engagement stability of the first outer support member 142 within the buckle groove 1215.

[0239] Alternatively, in another embodiment, please refer to Figure 40 and Figure 41 The first outer support member 142 may further include a first connecting portion 14201 and a second connecting portion 14202, which are two independent separate structures. The first connecting portion 14201 includes an inner support arm 1422 and a first end cap 14241, and the second connecting portion 14202 includes a second snap-fit ​​portion 1423 and a second end cap 14242. The first end cap 14241 and the second end cap 14242 are combined to form the aforementioned end cap 1424. When the first outer support member 142 needs to be inserted into the snap-fit ​​groove 1215, the first connecting portion 14201 and the second connecting portion 14202 can be inserted into the snap-fit ​​groove 1215 separately. This arrangement can also achieve the snap-fit ​​connection between the first outer support member 142 and the housing 180, achieving the beneficial effects of the above embodiment.

[0240] Optionally, please refer to Figure 33 , Figure 35 and Figure 42 In one embodiment of this utility model, the housing 180 includes a guide wall 1803, which is disposed within the clearance groove 1802 and extends along the sliding direction of the first outer support member 142. The housing connecting portion 1212 also includes a guide member 12121, which is inserted into the clearance groove 1802 and abuts against the guide wall 1803. The number of guide walls 1803 is not limited; there can be one or two. Optionally, in this embodiment, two guide walls 1803 are provided, and the two guide walls 1803 are arranged opposite each other along the length direction of the clearance groove 1802. It should be noted that the length direction of the clearance groove 1803 is the same as the moving direction of the first support 121 and the second support 122, such as... Figure 33 As shown in the W4 direction.

[0241] By providing guide 12121 and guide wall 1803, and ensuring that guide 12121 and guide wall 1803 cooperate with each other, a guiding function can be provided when the housing connection 1212 is connected to the housing 180, facilitating the connection between the housing connection 1212 and the housing 180, thereby facilitating the installation between the bracket assembly 120 and the housing 120. Simultaneously, because guide 12121 and guide wall 1803 are in contact, friction is generated between them. This friction helps the bracket assembly 120 remain stationary relative to the housing 180, thereby further reducing the possibility of the first outer support 142 detaching from the first bracket 121 and the second bracket 122 along the sliding direction.

[0242] To improve the smoothness of sliding of the first outer support 142 between the first bracket 121 and the second bracket 122, optionally, in one embodiment of this utility model, please refer to... Figure 15 , Figure 20 , Figure 40 and Figure 43 The first outer support member 142 includes a first guide slope 1421 on the side facing the second support 122, and the first guide slope 1421 is disposed on the inner support arm 1422. The second support 121 includes a second guide slope 127, and the first guide slope 1421 slides along the second guide slope 127 to achieve mutual approach or separation of the first support 121 and the second support 122. In another embodiment, the first outer support member 142 may also include a first guide slope 1421 on the side facing the first support 121, and the first guide slope 1421 may be disposed on the inner support arm 1422. The first support 121 includes a second guide slope 127, and the first guide slope 1421 slides along the second guide slope 127. In other embodiments, the first outer support member 142 may have a first guide slope 1421 on both sides facing the first bracket 121 and the second bracket 122, and a second guide slope 127 on both the first bracket 121 and the second bracket 122. The first guide slope 1421 on both sides of the first outer support member 142 may slide with the second guide slope 127 on the corresponding side.

[0243] The coordinated design of the first guide slope 1421 and the second guide slope 127 not only guides the sliding of the first outer support 142 between the first bracket 121 and the second bracket 122, reducing the probability of offset or misalignment during sliding, but also improves the smoothness of the separation and approach of the first bracket 121 and the second bracket 122. Furthermore, the mutual contact between the first guide slope 1421 and the second guide slope 127 also creates a larger contact area between the first outer support 142 and the first bracket 121 and the second bracket 122 when the first bracket 121 and the second bracket 122 are in a separated state, which helps to reduce the probability of the first outer support 142 shifting or coming off.

[0244] Furthermore, when the first outer support 142 needs to slide out from between the first bracket 121 and the second bracket 122, the end cap 1424 slides in the opposite direction, causing the end cap 1424 to slide from the second mounting position to the first mounting position. At this time, the pulling force of the pulling member 130 will cause the first bracket 121 and the second bracket 122 to move closer to each other. Since the first guide slope 1421 and the second guide slope 127 are sloped together, the movement of the first bracket 121 and the second bracket 122 moving closer to each other will cause the first outer support 142 to be automatically squeezed from the first position to the second position, thereby improving the convenience of sliding the first outer support 142 out from between the first bracket 121 and the second bracket 122 and improving the user experience.

[0245] To further reduce the probability of the first outer support 142 skewing or shifting when sliding between the first bracket 121 and the second bracket 122, and to ensure smooth sliding, optionally, in one embodiment of this utility model, please refer to... Figure 18 , Figure 20 and Figure 44 The first guide slope 1421 is disposed on the side of the first outer support 142 facing the second bracket 122, and the second guide slope 127 is disposed on the second bracket 122. Figure 18 As shown, the first bracket 121 has a sliding groove 125 at the end away from the base 141, and the sliding groove 125 is disposed opposite to the first outer support member 142. The side of the first outer support member 142 facing away from the first guide slope 1421 is at least partially accommodated in the sliding groove 125. Along the height direction of the bracket assembly 120, the upper wall of the sliding groove 125 abuts against the upper side surface of the first outer support member 142, the lower wall of the sliding groove 125 abuts against the lower side surface of the first outer support member 142, and the bottom wall of the sliding groove 125 abuts against the side wall of the first outer support member 142 facing away from the first guide slope 1421.

[0246] In other embodiments, the first guide ramp 1421 may be disposed on the side of the first outer support 142 facing the first bracket 121, and the second guide ramp 127 may be disposed on the first bracket 121. The second bracket 122 may have a groove 125 at the end away from the seat 141, and the side of the first outer support 142 away from the first guide ramp 1421 may be at least partially accommodated in the groove 125.

[0247] By providing the slide groove 125, when the first outer support member 142 slides between the first bracket 121 and the second bracket 122, the side of the first outer support member 142 facing away from the first guide slope 1421 can slide along the slide groove 125. At the same time, the slide groove 125 can also provide guidance and limitation for the first outer support member 142 along the height direction of the bracket assembly 120, further reducing the probability of skewness and displacement during the sliding of the first outer support member 142, thereby further ensuring the smoothness of the sliding of the first outer support member 142 between the first bracket 121 and the second bracket 122.

[0248] Furthermore, to prevent the first outer support 142 from falling between the first bracket 121 and the second bracket 122 during sliding, optionally, in one embodiment of this utility model, please refer to... Figure 9 , Figure 36 , Figure 44 and Figure 45 A limiting rod 126 is provided on the first bracket 121, and the limiting rod 126 extends through the sliding groove 125 in the height direction. The limiting rod 126 can be inserted into the first bracket 121 or fixedly connected to the first bracket 121 by threads. A limiting groove 1425 is provided on the first outer support member 142, and the two ends of the limiting groove 1425 are closed ends in the length direction, and the length direction of the limiting groove 1425 is consistent with the sliding direction of the first outer support member 142. The limiting rod 126 passes through the limiting groove 1425 and can slide along the length direction of the limiting groove 1425. The dimension of the limiting groove 1425 along the width direction of the bracket assembly 120 is larger than the outer diameter of the limiting rod 126, so that the limiting rod 126 can slide along the width direction of the limiting groove 1425, thereby providing clearance space for the first bracket 121 and the second bracket 122 to approach and move away from each other.

[0249] Through the cooperation of the limiting groove 1425 and the limiting rod 126, on the one hand, the limiting rod 126 slides along the limiting groove 1425, which can guide the sliding of the first outer support member 142 between the first bracket 121 and the second bracket 122. On the other hand, the cooperation between the limiting rod 126 and the limiting groove 1425 can also prevent the first outer support member 142 from falling off after it comes out from between the first bracket 121 and the second bracket 122, thereby preventing the first outer support member 142 from being lost.

[0250] To enable the insertion between the bracket assembly 120 and the base 141, optionally, in one embodiment of this utility model, please refer to... Figure 15 and Figure 46The first bracket 121 has a first mounting portion 1217 connected to one end near the base 141, and the second bracket 122 has a second mounting portion 1222 connected to one end near the base 141. The base 141 is provided with a first pair of interfaces 1411 and a second pair of interfaces 1412. The first pair of interfaces 1411 is used for docking with the first docking portion 1217, and the second pair of interfaces 1412 is used for docking with the second docking portion 1222. The outer support assembly 140 also includes a second outer support member 143. One end of the second outer support member 143 is connected to the base 141, and the other end of the second outer support member 143 is slidably inserted between the first mounting portion 1217 and the second mounting portion 1222. When the second outer support 143 is inserted between the first mounting part 1217 and the second mounting part 1222, the first mounting part 1217 and the second mounting part 1222 separate along the width direction of the bracket assembly 120, so that the first mounting part 1217 is inserted into the first pair of interfaces 1411 and the second mounting part 1222 is inserted into the second pair of interfaces 1412, thereby realizing the insertion between the first bracket 121 and the second bracket 122 and the base 141.

[0251] By providing a second external support member 143 at one end of the base 141 and allowing the second external support member 143 to slide between the first mounting portion 1217 and the second mounting portion 1222, the first bracket 121 and the second bracket 122 can be separated at the end near the base 141, and the first bracket 121 and the second bracket 122 can be kept in a separated state, thus providing external support. This arrangement facilitates the insertion and connection between the first bracket 121 and the second bracket 122 and the base 141, which helps to improve the connection efficiency between the bracket assembly 120 and the base 141.

[0252] To improve the sliding connection accuracy of the second outer support member 143 relative to the bracket assembly 120, optionally, in one embodiment of this utility model, please refer to... Figure 17 , Figure 46 and Figure 47 The second outer support member 143 has an abutment portion 1431 at one end opposite to the seat body 141. The abutment portion 1431 includes two sets, one set of abutment portions 1431 is provided on the side wall of the second outer support member 143 facing the first mounting portion 1217, and the other set of abutment portions 1431 is provided on the side wall of the second outer support member 143 facing the second mounting portion 1222.

[0253] Please see Figure 15 , Figure 17 , Figure 23 , Figure 47 and Figure 48The first mounting portion 1217 and the second mounting portion 1222 are each provided with a third guide slope 1204 on their opposite side walls. The abutment portion 1431 on each side corresponds to a third guide slope 1204 on the same side. During the process of the second outer support 143 slidingly inserting into the first mounting portion 1217 and the second mounting portion 1222, the abutment portion 1431 slides along the third guide slope 1204 to realize the mutual separation or retraction of the first mounting portion 1217 and the second mounting portion 1222, thereby realizing the mutual retraction or separation of the first bracket 121 and the second bracket 122 near the end of the seat 141.

[0254] The abutment portion 1431 can be a sloped structure or a combination of a plane and a sloped structure. Optionally, please refer to... Figure 17 and Figure 48 In this embodiment, the abutment portion 1431 includes an inclined section 1434 and a flat section 1433 connected to each other, with the flat section 1433 connected to the end of the inclined section 1434 away from the seat 141. The first bracket 121 and the second bracket 122 each have a flat guide section 1205 on their oppositely arranged side walls. Figure 49 As shown, when the first bracket 121 and the second bracket 122 approach each other, the planar guide sections 1205 on both sides fit together to limit the fitting distance between the first bracket 121 and the second bracket 122. Figure 50 As shown, when the first bracket 121 and the second bracket 122 separate from each other, that is, when the second outer support 143 slides between the first mounting part 1217 and the second mounting part 1222, the planar guide sections 1205 on both sides gradually separate to form an insertion area 1206 for the abutment part 1431 to be inserted, and the planar sections 1433 on both sides abut against the planar guide sections 1205 on both sides respectively.

[0255] Please see Figure 48 and Figure 50 When the second outer support 143 is inserted between the first mounting part 1217 and the second mounting part 1222, the flat sections 1433 on both sides of the abutment part 1431 first slide along the corresponding third guide slopes 1204, and drive the sloped sections 1434 on both sides to gradually slide into the space between the two third guide slopes 1204. As the first bracket 121 and the second bracket 122 separate, the flat guide sections 1205 on both sides gradually separate to form the insertion area 1206. The abutment part 1431 continues to slide, the front flat section 1433 gradually enters the insertion area 1206 and abuts against the corresponding flat guide section 1205, and the rear sloped section 1434 gradually fits completely against the third guide slope 1204. At this time, it indicates that the second outer support 143 is inserted in place, and the insertion action stops.

[0256] Through the cooperation of the third guide ramp 1204 and the planar guide section 1205, the planar section 1433 and the ramp section 1434 of the abutment part 1431 can gradually slide in and be precisely positioned. This design reduces the probability of the second outer support member 143 deviating from the preset direction during sliding between the first bracket 121 and the second bracket 122, thereby improving the positioning accuracy of the second outer support member 143 and ensuring consistency in multiple insertions. Furthermore, after the second outer support member 143 is inserted, the contact between the planar section 1433 and the planar guide section 1205, and the fit between the ramp section 1434 and the third guide ramp 1204, effectively disperses the external load generated between the second outer support member 143 and the bracket assembly 120. This load dispersion mechanism enhances the overall stability and load-bearing capacity of the connection structure between the bracket assembly 120 and the base 141, while also reducing local stress concentration and extending the service life of the structure.

[0257] Given that the outer support assembly 140 includes a first outer support member 142 and a second outer support member 143, there are multiple ways to assemble and disassemble the bracket assembly 120 and the outer support assembly 140. In one embodiment, when the bracket assembly 120 needs to be installed on the outer support assembly 140, the first outer support member 142 can be inserted into one end of the first bracket 121 and the second bracket 122 outside the housing 180. Then, the bracket assembly 120 is moved into the receiving cavity 190, so that the second outer support member 143 is inserted between the first bracket 121 and the second bracket 122. This completes the connection between the bracket assembly 120 and the outer support assembly 143, and also achieves the tensioning of the cleaning member 110. Accordingly, when the support assembly 120 needs to be removed from the outer support assembly 140, the first outer support member 142 can be slid out from between the first support 121 and the second support 122, and then the support assembly 120 can be moved to the outside of the receiving cavity 190 so that the second outer support member 143 can slide out from between the first support 121 and the second support 122. This completes the removal of the support assembly 120 from the outer support assembly 140, and also relaxes the cleaning member 110.

[0258] In another embodiment, when the support assembly 120 needs to be installed onto the outer support assembly 140, the support assembly 120, together with the cleaning member 110 and the first support member 142, can be moved to the receiving cavity 190 first, so that the second outer support member 143 is inserted between the first support 121 and the second support 122, and then the first outer support member 142 is slidably inserted between the first support 121 and the second support 122. This also achieves the connection between the support assembly 120 and the outer support assembly 140, and also achieves the tensioning of the cleaning member 110. Correspondingly, when the support assembly 120 needs to be removed from the outer support assembly 140, the support assembly 120 can be moved outward of the receiving cavity 190 first, so that the second outer support member 143 slides out from between the first support 121 and the second support 122, and then the first outer support member 142 slides out from between the first support 121 and the second support 122. This also achieves the removal of the support assembly 120 from the outer support assembly 140, and also achieves the relaxation of the cleaning member 110. In actual use, users can choose according to their own operating habits.

[0259] To further improve the insertion and positioning accuracy between the second outer support 143 and the first bracket 121 and the second bracket 122, optionally, in one embodiment of this utility model, please refer to... Figure 27 , Figure 28 , Figure 47 and Figure 48 The second outer support member 143 also includes a insertion slot 1432. Two sets of insertion slots 1432 are provided, one set facing the first mounting portion 1217 and the other facing the second mounting portion 1222. Both the first mounting portion 1217 and the second mounting portion 1222 have corresponding locking blocks 128 on their opposite side walls. The locking blocks 128 are inserted into the insertion slots 1432 and can slide along them. Along the height direction of the bracket assembly 120, the upper wall of the insertion slot 1432 abuts against the upper side wall of the locking block 128, and the lower wall of the insertion slot 1432 abuts against the lower side wall of the locking block 128. By providing a insertion slot 1432 and a snap-fit ​​block 128, the insertion slot 1432 and the snap-fit ​​block 128 cooperate to achieve positioning of the second outer support member 143 along the height direction of the bracket assembly 120 when it is inserted between the first bracket 121 and the second bracket 122. Therefore, the insertion positioning accuracy between the second outer support member 143 and the first bracket 121 and the second bracket 122 can be further improved, and the insertion efficiency between the first bracket 121 and the second bracket 122 and the base 141 can be improved accordingly.

[0260] To improve the cleaning efficiency of the cleaning component 110 and reduce the frequency of replacement, optionally, in one embodiment of this utility model, please refer to... Figure 4 and Figure 31 The support assembly 120 also includes a roller structure rotatably mounted on the support body. The roller structure includes a roller body, and at least two sets of roller structures are provided on the support body. One set of roller structures has a first roller 1201 as its roller body, and the other set has a second roller 1202 as its roller body. Both the first roller 1201 and the second roller 1202 are rotatably connected to the support body. Specifically, the first roller 1201 is rotatably mounted on the outside of the first support 121, that is, on the side of the first support 121 opposite to the second support 122. The second roller 1202 is rotatably mounted on the outside of the second support 122, that is, on the side of the second support 122 opposite to the first support 121, and the second roller 1202 is arranged parallel to the first roller 1201.

[0261] The cleaning component 110 is wound around and covers the outer circumferential surface of the first roller 1201 and the second roller 1202. When the first roller 1201 and the second roller 1202 rotate, they can drive the cleaning component 110 to rotate. It should be noted that the first roller 1201 and the second roller 1202 can be unpowered rollers, that is, the rotation is achieved by the friction between the cleaning component 110 and the surface to be cleaned. One of the first roller 1201 and the second roller 1202 can also be a powered roller and the other is an unpowered driven roller. For example, a drive component can be provided at one end of the first roller 1201 or the second roller 1202. The drive component rotates, driving the first roller 1201 or the second roller 1202 to rotate, and in turn driving the cleaning component 100 to rotate.

[0262] By setting the first roller 1201 and the second roller 1202, the cleaning component 110 can be rotated, allowing the entire outer circumferential surface of the cleaning component 110 to contact the surface to be cleaned for cleaning. This increases the working area of ​​the cleaning component 110, thereby reducing the number of times the cleaning component 110 can be replaced and improving the cleaning efficiency of the cleaning component 110.

[0263] The roller body also includes a first end seat and a second end seat, which are detachably connected to the support body. The roller body is rotatably connected between the first end seat and the second end seat, and is detachably installed between the first end seat and the second end seat. This configuration allows the first end seat and / or the second end seat to be removed from the support body, enabling the roller body to be disassembled. This allows for replacement of the roller body in case of deformation or damage. It also facilitates the user's simultaneous removal of the roller body, the first end seat, and the second end seat from the support assembly, simplifying subsequent cleaning and maintenance.

[0264] In one embodiment, the first end seat is detachably connected to the support body, and the second end seat is fixedly connected to the support body; in another embodiment, the first end seat is fixedly connected to the support body, and the second end seat is detachably connected to the support body. This configuration allows one of the first and second end seats to be detached from the support body, while the other cannot, simplifying the alignment of the roller body and the installation of the first or second end seat. Furthermore, the non-detachable component reduces the possibility of loss, thereby improving the user experience.

[0265] First, the following embodiments will describe in detail the connection structure between the first roller 1201 and the support assembly 120, and between the first roller 1201 and the seat 141 when the roller body is the first roller 1201.

[0266] Please see Figure 52 and Figure 53 The support assembly 120 further includes a first support base 12011 and a second support base 12012. When the roller body is the first roller 1201, the first end seat is the first support base 12011, and the second end seat is the second support base 12012. The first support base 12011 and the second support base 12012 are respectively fixedly connected to both ends of the first support 121 along its length. Specifically, the first support base 12011 is fixedly connected to one end of the first support 121 near the housing connection portion 1212. This fixed connection can be an integral injection molding connection or a connection using fasteners such as bolts. Optionally, in this embodiment, please refer to... Figure 52 and Figure 60 The first support base 12011 is integrally formed and connected to the first bracket 121. The second support base 12012 is detachably connected to the end of the first bracket 121 near the base body 141. The detachable connection method can be a bolted detachable connection, a snap-fit ​​detachable connection, etc. Please refer to [link / reference]. Figure 60 , Figure 62 and Figure 63 The first support 12011 is provided with a first insertion hole 12017, and the second support 12012 is provided with a second insertion hole 12018. It should be noted that in this embodiment, the second support 12012 and the first mounting part 1217 in the aforementioned embodiment are the same component.

[0267] Please see Figures 53 to 55The first roller 1201 has a first shaft end 12014 at one end and a second shaft end 12015 at the other end. Both the first shaft end 12014 and the second shaft end 12015 are rotatably connected to the support body. The first shaft end 12014 is located near the housing connection portion 1212, and the second shaft end 12015 is located near the base 141. The cleaning assembly 100 also includes a drive structure 160, which is connected to the base 141. The second shaft end 12015 is drivenly connected to the drive structure 160, and the shaft diameter of the second shaft end 12015 is larger than that of the first shaft end 12014. With this configuration, the second shaft end 12015 can withstand greater torque, allowing the power of the drive structure 160 to be transmitted to the first roller 1201 more stably. In addition, since the shaft diameter of the second shaft end 12015 is larger than that of the first shaft end 12014, the different shaft diameters of the first shaft end 12014 and the second shaft end 12015 have a foolproof effect during the process of installing the bracket assembly 120 with the cleaning component 110 into the receiving cavity 190. This can prevent the user from installing the bracket assembly 120 with the cleaning component 110 backwards in the receiving cavity 190, thereby increasing the probability that the user can accurately install the bracket assembly 120.

[0268] Please see Figures 53 to 55 A first shaft end 12014 is rotatably connected to a first bearing 12005, and the first shaft end 12014 is rotatably connected to the bracket body via the first bearing 12005. A first snap-fit ​​member 12016 is provided on the first shaft end 12014, and the first snap-fit ​​member 12016 is sleeved outside the first bearing 12005, and is rotatably connected to the first shaft end 12014 via the first bearing 12005. A second shaft end 12015 is rotatably connected to a rotating sleeve 12019, and is rotatably connected to the bracket body via the rotating sleeve 12019. The wall thickness of the rotating sleeve 12019 is less than the wall thickness of the first bearing 12005, and the inner diameter of the rotating sleeve 12019 is larger than the inner diameter of the first bearing. The first snap-fit ​​member 12016 is inserted into a first insertion hole 12017, and the rotating sleeve 12019 is inserted into a second insertion hole 12018. Please refer to [link to relevant documentation]. Figure 56 The rotating sleeve 12019 and the second shaft end 12015 are rotatably connected by a shaft-hole fit, and the rotating sleeve 12019 is made of a self-lubricating material. The self-lubricating material can be polyoxymethylene-based material, polyamide-based material, metal-plastic composite self-lubricating material, etc. Specifically, the outer ring of the rotating sleeve 12019 is tightly fitted with the second insertion hole 12018 to achieve a fixed connection between the rotating sleeve 12019 and the second insertion hole 12018, and the inner ring of the rotating sleeve 12019 is clearance-fitted with the second shaft end 12015 to achieve a rotatable connection between the second shaft end 12015 and the rotating sleeve 12019.

[0269] In the prior art, the rotational connection between the second shaft end 12015 and the second insertion hole 12018 is usually achieved by bearings. However, since the shaft diameter of the first shaft end 12014 needs to be larger than the shaft diameter of the second shaft end 12015, and the internal space of the second insertion hole 12018 is limited, the current bearing manufacturing process cannot manufacture a bearing whose outer diameter is adapted to the second insertion hole 12018 and whose inner diameter is adapted to the second shaft end 12015. This is because bearings usually include an outer ring, an inner ring, and rolling elements. The rolling elements are located between the outer ring and the inner ring. Due to the limitation of the rolling elements, the minimum value of the bearing wall thickness is limited. In this embodiment, a rotating sleeve 12019 is used to achieve a rotatable connection between the second shaft end 12015 and the second insertion hole 12018. The structure of the rotating sleeve 12019 is simpler than that of a bearing. Current manufacturing processes are fully capable of producing a rotating sleeve 12019 with an outer diameter that matches the second insertion hole 12018 and an inner diameter that matches the second shaft end. This provides feasibility for the shaft diameter of the second shaft end 12015 to be greater than that of the first shaft end 12014, and for both the first shaft end 12014 and the second shaft end 12015 to be rotatably connected to the bracket body.

[0270] Please see Figure 55 The first roller 1201 includes a first inner core 120005, which is made of metal and is integrally formed between the first shaft end 12014 and the second shaft end 12015. The second roller 1202 includes a second inner core 120006, which is also made of metal. The shaft diameter of the first inner core 120005 is larger than that of the second inner core 120006. This configuration allows the first inner core 120005 to withstand greater torque, enabling a more stable transmission of power from the drive structure 160 to the first roller 1201.

[0271] To further improve the insertion efficiency between the first connector 12016 and the first support base 12011, optionally, in one embodiment, please refer to... Figure 55The first snap-fit ​​connector 12016 includes a cylindrical segment 12071 and a frustoconical segment 12072 connected to each other, with the frustoconical segment 12072 positioned at the end of the cylindrical segment 12071 facing the first insertion hole 12017. The first insertion hole 12017 includes a cylindrical hole 12081 and a frustoconical hole 12082 connected to each other, with the cylindrical hole 12081 matching the cylindrical segment 12071 and the frustoconical hole 12082 matching the frustoconical segment 12072. This configuration allows the frustoconical segment 12072 to provide initial centering and positioning when the first snap-fit ​​connector 12016 is inserted into the first insertion hole 12017, facilitating smooth insertion and improving insertion efficiency. On the other hand, when the first snap-fit ​​member 12016 is inserted into the first insertion hole 12017, it not only forms a conical surface fit between the frustum section 12072 and the frustum hole 12082, but also a cylindrical surface fit between the cylindrical section 12071 and the cylindrical hole 12081. Therefore, a double-fit positioning structure is formed, which helps improve the stability of the insertion between the two. It should be noted that, to facilitate the axial positioning between the first snap-fit ​​member 12016 and the first support base 12011, the first insertion hole 12017 on the first support base 12011 is a blind hole structure.

[0272] Alternatively, in one embodiment, please refer to Figure 55The first insertion hole 12017 includes a first bottom wall 12091, the first bottom wall 12091 is provided with a positioning protrusion 12092, and a first positioning hole 12093 is formed between the positioning protrusion 12092, the side wall of the frustoconical hole 12082, and the first bottom wall 12091. The first snap-fit ​​member 12016 is provided with a stepped section 120161 and a through hole section 120162, the through hole section 120162 being located at one end near the first bottom wall 12091. The stepped section 120161 is used to install the first bearing 12005. The first shaft end 12014 passes through the first bearing 12005 and extends at least partially into the through hole section 120162, and the extension length does not exceed the frustoconical section 12072 of the first snap-fit ​​member 12016. The frustoconical section 12072 of the first snap-fit ​​member 12016 is at least partially accommodated within the first positioning hole 12093, and the end face of the frustoconical section 12072 abuts against the first bottom wall 12091 in the axial direction. The positioning protrusion 12092 engages with the through-hole section 120162, correspondingly inserting into the through-hole section 120162 and forming an axial gap with the first shaft end 12014. This configuration allows the frustoconical section 12072 of the first snap-fit ​​member 12016 to be inserted into the first positioning hole 12093, while the positioning protrusion 12092 is correspondingly inserted into the through-hole section 120162. This structural design makes the insertion and positioning between the first snap-fit ​​member 12016 and the first insertion hole 12017 more precise, ensuring alignment accuracy during assembly. Meanwhile, due to the mutual cooperation between the frustum section 12072 and the first positioning hole 12093, and between the positioning protrusion 12092 and the through hole section 120162, the first snap-fit ​​part 12016 is easier to align when inserted into the first insertion hole 12017, which reduces the adjustment time and operation difficulty in the assembly process and improves the assembly efficiency.

[0273] To achieve the connection between the first roller 1201 and the base 141, optionally, in one embodiment of this utility model, please refer to... Figure 54 , Figure 63 , Figure 64 and Figure 67 The second insertion hole 12018, located on the second support base 12012, is a through hole structure. The second shaft end 12015 extends through the rotating sleeve 12019 and out of the second insertion hole 12018. The portion of the second shaft end passing through the second support base forms a driving section, which is drivenly connected to the driving structure. The base body 141 includes a first connecting shaft 12001, and the first mating interface 1411 includes a first mounting hole 14111. The first connecting shaft 12001 passes through the first mounting hole 14111. The first connecting shaft 12001 can be rotatably connected to the first mounting hole 14111 or fixedly connected to the first mounting hole 14111. Optionally, in this embodiment, please refer to... Figure 54 and Figure 64A second bearing 12003 is provided in the first mounting hole 14111. The first connecting shaft 12001 is rotatably connected to the first mounting hole 14111 through the second bearing 12003, so as to realize the rotatable connection of the first connecting shaft 12001 relative to the seat 141. A blind insertion hole 12002 is provided on the side of the first connecting shaft 12001 facing the second support seat 12012. The second shaft end 12015 is inserted into the blind insertion hole 12002. Specifically, the driving section of the second shaft end 12015 is inserted into the blind insertion hole 12002.

[0274] This design offers several advantages. First, it facilitates the insertion of the first roller 1201 into the base 141, simplifying the connection process and enabling rapid axial positioning and connection. It also reduces alignment difficulties during assembly, improving assembly efficiency. Second, by designing the second insertion hole 12018 as a through-hole structure, the second shaft end 12015 can penetrate the rotating sleeve 12019 and extend to the outside. This design provides greater flexibility in the connection between the first roller 1201 and the base 141. Furthermore, the connection method (rotational or fixed connection) between the first connecting shaft 12001 and the base 141 can be selected according to actual needs, further enhancing the structure's adaptability and stability.

[0275] Secondly, the following embodiments will describe in detail the connection between the second roller 1202 and the support assembly 120 when the roller body is the second roller 1202.

[0276] Alternatively, in one embodiment, please refer to Figure 52 and Figure 56 The support assembly 120 further includes a third support base 12023 and a fourth support base 12024. When the roller body is the second roller 1202, the first end seat is the third support base 12023, and the second end seat is the fourth support base 12024. The third support base 12023 and the fourth support base 12024 are respectively fixedly connected to both ends of the second support 122 along its length. Specifically, the third support base 12023 is fixedly connected to one end of the second support 122 near the housing connection portion 1212. This fixed connection can be an integral injection molding connection or a connection using bolts or other fasteners. Optionally, in this embodiment, please refer to... Figure 52 and Figure 60 The third support 12023 is integrally formed and connected to the second bracket 122. The third support 12023 is slidably connected to the housing connection part 1212, and the sliding direction is consistent with the direction of relative movement of the first bracket 121 and the second bracket 122. The fourth support 12024 is detachably connected to the end of the second bracket 122 near the base 141. The detachable connection method can be a bolted detachable connection, a snap-fit ​​detachable connection, etc. Please refer to [link / reference]. Figure 60 and Figure 61The third support 12023 is provided with a third insertion hole 12028, and the fourth support 12024 is provided with a fourth insertion hole 12029. It should be noted that in this embodiment, the fourth support 12024 is the same component as the second connecting part 1222 in the aforementioned embodiment.

[0277] It should be noted that there are multiple ways in which the third support 12023 can be slidably connected to the housing connection 1212. Optionally, in this embodiment, please refer to... Figure 59 and Figure 60 The housing connection portion 1212 is provided with a bracket slide groove 1214, which extends along the direction in which the first bracket 121 and the second bracket 122 move relative to each other. The third support base 12023 is engaged with the bracket slide groove 1214 and can slide along the bracket slide groove 1214 in the following direction: Figure 60 As shown in the W5 direction.

[0278] Please see Figures 56 to 58 The second roller 1202 has a third shaft end 12025 at one end and a fourth shaft end 12026 at the other end. The shaft diameters of the third shaft end 12025 and the fourth shaft end 12026 are smaller than the shaft diameter of the second shaft end 12015. The third shaft end 12025 is located near the housing connection portion 1212, and the fourth shaft end 12026 is located near the base 141. The third shaft end 12025 is rotatably connected to a third snap-fit ​​member 12027, and the fourth shaft end 12026 is rotatably connected to a fourth snap-fit ​​member 12022. The third snap-fit ​​member 12027 is inserted into a third insertion hole 12028, and the fourth snap-fit ​​member 12022 is inserted into a fourth insertion hole 12029. The rotatable connection between the third snap-fit ​​member 12027 and the third shaft end 12025, and between the fourth snap-fit ​​member 12022 and the fourth shaft end 12026, can be achieved through bearings or through shaft hole mating. Optionally, in this embodiment, the third snap-fit ​​member 12027 is rotatably connected to the third shaft end 12025 via the third bearing 12004, and the fourth snap-fit ​​member 12022 is rotatably connected to the fourth shaft end 12026 via the fourth bearing 12006. Both the third insertion hole 12028 and the fourth insertion hole 12029 are blind hole structures.

[0279] In one embodiment, the insertion structure between the third snap-fit ​​member 12027 and the third insertion hole 12028, and the insertion structure between the fourth snap-fit ​​member 12022 and the fourth insertion hole 12029, can both adopt the insertion method of the first snap-fit ​​member 12016 and the first insertion hole 12017 in the above embodiment.

[0280] Of course, in other embodiments, the insertion structure between the third snap-fit ​​member 12027 and the third insertion hole 12028, and the insertion structure between the fourth snap-fit ​​member 12022 and the fourth insertion hole 12029 can also adopt a connection method different from the insertion method between the first snap-fit ​​member 12016 and the first insertion hole 12017 in the above embodiments, as long as the insertion requirements can be met.

[0281] To achieve the connection between the second roller 1202 and the base 141, optionally, in one embodiment of this utility model, please refer to... Figure 57 , Figure 61 and Figure 67 The second pair of interfaces 1412 also includes a second mounting hole 14121. The side of the fourth support 12024 facing the base 141 also includes a mating end 120241 adapted to the second mounting hole 14121. The mating end 120241 is located at the end of the second roller 1202 facing the base 141 and is inserted into the second mounting hole 14121. By inserting the mating end 120241 of the fourth support 12024 into the second mounting hole 14121 along the axial direction of the second roller 1202, the fourth support 12024 and the base 141 can be connected. This connection method has a simple structure, high insertion positioning accuracy, and is more suitable for repeated connection conditions between the second roller 1202 and the base 141.

[0282] Because the first roller 1201 and the second roller 1202 are subjected to a large tension force when the cleaning component 110 is in a tensioned state, their support stability is affected. Therefore, in order to improve the stability of the support provided by the first roller 1201 and the second roller 1202 for the cleaning component 110, optionally, in one embodiment of this utility model, please refer to... Figure 52 and Figure 68 The first roller 1201 and the second roller 1202 are further provided with a retaining section 1203 at a position near the middle of their own length. The retaining section 1203 is a small-diameter shaft segment provided on the first roller 1201 or the second roller 1202. When the cleaning member 110 is wound on the first roller 1201 and the second roller 1202, the retaining section 1203 may or may not contact the cleaning member 110. Optionally, in this embodiment, please refer to... Figure 68The inner wall of the cleaning component 110 is provided with a protruding ring structure 111 corresponding to the abutment section 1203. The protruding ring structure 111 can engage with the abutment section 1203, thereby providing a positioning function for the cleaning component 110 in the length direction of the bracket assembly 120. The first bracket 121 and the second bracket 122 are respectively provided with support portions 129. The support portion 129 on the first bracket 121 extends toward the abutment section 1203 on the first roller 1201 and rotatably abuts against the corresponding abutment section 1203. The support portion 129 on the second bracket 122 extends toward the abutment section 1203 on the second roller 1202 and rotatably abuts against the corresponding abutment section 1203.

[0283] In other embodiments, a supporting section 1203 may be provided on one of the first roller 1201 and the second roller 1202, and a supporting portion 129 may be provided on the first bracket 121 or the second bracket 122 corresponding to the supporting section 1203. This can also improve the support stability of the first roller 1201 and the second roller 1202 on the cleaning member 110.

[0284] By setting the abutment section 1203 and the support part 129, the abutment section 1203 and the support part 129 are rotated to abut against each other. This can form an additional abutment force between the two ends of the first roller 1201 and the second roller 1202, which is opposite to the tension force of the cleaning component 110. This can offset part of the tension force generated by the cleaning component 110 on the first roller 1201 and the second roller 1202, reduce the probability of the first roller 1201 and the second roller 1202 bending and deforming under stress, and thus improve the support stability of the first roller 1201 and the second roller 1202 on the cleaning component 110.

[0285] To generate better friction between the cleaning component 110 and the first roller 1201 or the second roller 1202, and to reduce the probability of slippage during the rotation of the cleaning component 110, optionally, please refer to... Figure 53 and Figure 56In one embodiment of this utility model, at least a portion of the outer peripheral surfaces of the first roller 1201 and the second roller 1202 are made of rubber. Here, "at least a portion of the outer peripheral surfaces of the first roller 1201 and the second roller 1202 that contact the cleaning component 110 are made of rubber. In one embodiment, both the outer peripheral surfaces of the first roller 1201 and the second roller 1202 that contact the cleaning component 110 may be made of rubber. Alternatively, only one of the first roller 1201 and the second roller 1202 may have an outer peripheral surface made of rubber that contacts the cleaning component 110. Furthermore, the outer peripheral surfaces of the first roller 1201 and the second roller 1202 that contact the cleaning component 110 may be made of rubber. The rubber material may be a rubber ring structure covering the outer peripheral surface of the first roller 1201 or the second roller 1202, or it may be a structure with multiple dot-shaped rubber protrusions, strip-shaped rubber protrusions, etc., distributed on the first roller 1201 or the second roller 1202. In the actual design and production process, the actual rotational friction between the cleaning component 110 and the first roller 1201 and the second roller 1202 needs to be determined. The rubber material can be hard rubber or soft rubber, as long as it meets the transmission requirements between the first roller 1201 and the second roller 1202 and the cleaning component 110.

[0286] By applying rubber material to the outer circumferential surfaces of the first roller 1201 and the second roller 1202, the transmission friction between the cleaning component 110 and the first roller 1201 and the second roller 1202 can be increased, improving friction conditions and reducing the probability of slippage during rotation, thereby enhancing the cleaning effect of the cleaning component 110. Simultaneously, since the rubber material also has certain shock absorption and noise reduction properties, it can also reduce the noise generated during the operation of the cleaning assembly 100, improving the user experience.

[0287] Optionally, in one embodiment of this utility model, please refer to Figure 6 and Figure 31 The cleaning component 100 also includes a drive structure 160, which is disposed on the base 141 and drives the first roller 1201 to rotate. Specifically, the drive structure 160 is driven and connected to the second shaft end 12015. The drive structure 160 can be a direct-drive structure of a motor, a combination structure of a motor and a gear assembly, a combination structure of a motor and a transmission belt, etc., as long as it can realize the rotation of the first roller 1201, this embodiment is not limited to this. The fixed end of the drive structure 160 is disposed on the base 141, and the output end of the drive structure 160 is connected to the first roller 1201. When the output end of the drive structure 160 rotates, it drives the first roller 1201 to rotate.

[0288] By setting up a drive structure 160, the rotation of the drive structure 160 drives the first roller 1201 to rotate, and the rotation of the first roller 1201 drives the cleaning component 110 and the second roller 1202 to rotate. Since the drive structure 160 can provide stable power output, the cleaning component 110 can achieve a stable rotational speed, thereby ensuring the stability of cleaning efficiency and cleaning effect. At the same time, it is not limited by the friction of the surface to be cleaned, making it suitable for more cleaning scenarios.

[0289] Optionally, in one embodiment of this utility model, please refer to Figure 31 and Figure 69 One end of the first connecting shaft 12001 is drivenly connected to the drive structure 160, which drives the first connecting shaft 12001 to rotate. The other end of the first connecting shaft 12001 extends out of the seat 141 and is connected to the second shaft end 12015. The drive structure 160 includes a first driving member 161 and a gear assembly 162. The first driving member 161 can be any mechanism capable of rotational motion, such as a motor or a hydraulic pump. Optionally, in this embodiment, the first driving member 161 is a motor. The input end of the gear assembly 162 is connected to the output end of the first driving member 161. The gear assembly 162 includes a first output end 1621, which is connected to the first roller 1201 to drive the first roller 1201 to rotate. The gear assembly 162 can include multiple sets of gear transmission structures or only one set of gear transmission structures, depending on meeting the transmission connection requirements between the motor and the first roller 1201.

[0290] Because the gear assembly 162 can achieve a compact layout through reasonable design, it can save installation space on the base 141, making the overall structure of the cleaning component 100 lighter and more compact. At the same time, the gear assembly 162 also has high transmission efficiency, which helps to improve the rotational efficiency of the cleaning component 110 and reduce energy loss.

[0291] Specifically, in this embodiment, please refer to Figure 69The gear assembly 162 includes a first gear structure 1623 and a second gear structure 1624. A first driving member 161 drives the first gear structure 1623 to rotate. A double-layer gear structure is provided on the output shaft of the first gear structure 1623, which are respectively labeled as the first gear 16231 and the second gear 16232 for ease of description. The first gear 16231 is connected to the second gear structure 1624 to drive the first roller 1201 to rotate, thereby driving the cleaning member 110 to rotate. The output end of the second gear structure 1624 forms the first output end 1621 of the gear assembly 1622. The first output end 1621 is provided with a first output gear 16211, which is mounted on a first connecting shaft 12001. Rotation of the first output gear 16211 drives the first connecting shaft 12001 to rotate, thereby driving the first roller 1201 to rotate. The seat 141 has a receiving cavity 1413 on the side opposite to the second outer support member 143, and the gear assembly 162 is disposed in the receiving cavity 1413. The seat 141 also includes a gearbox cover 14131, which is located at the opening of the receiving cavity 1413 and is detachably connected to the seat 141. The first gear structure 1623 and the second gear structure 1624 are both gear train structures, which will not be described in detail here.

[0292] In one embodiment, please refer to Figure 5 , Figure 54 , Figure 69 The gearbox cover 14131 has a third mounting hole 14132 on the side facing the first output gear 16211. A fifth bearing 12007 is installed in the third mounting hole 14132. One end of the first connecting shaft 12001 extending out of the first output gear 16211 is connected to the fifth bearing 12007 to achieve rotational support of the first connecting shaft 12001 on the gearbox cover 14131. With this configuration, the first output gear 16211 has a second bearing 12003 and a fifth bearing 12007 at both ends, which improves the support stability of the first connecting shaft 12001 for the first output gear 16211 and also improves the stability of the first connecting shaft 12001 during rotation.

[0293] By providing a gearbox cover 14131, the gearbox cover 14131 can effectively block external dust, impurities, moisture and other contaminants from entering the receiving cavity 1413, preventing these foreign objects from mixing into the gear assembly 162, thereby reducing the wear of the gear assembly and the decrease in meshing accuracy, and thus reducing the maintenance and replacement costs of the equipment.

[0294] To improve the transmission accuracy between the first roller 1201 and the first connecting shaft 12001 and reduce the probability of slippage between them, optionally, in one embodiment, please refer to... Figure 71The insertion blind hole 12002 on the first connecting shaft 12001 is a polygonal hole structure, such as a quadrilateral hole, hexagonal hole, or octagonal hole. The second shaft end 12015 of the first roller 1201 is a polygonal structure corresponding to the polygonal hole 1415. This design, because the combination of the polygonal hole and the polygonal structure provides a larger contact area and a tighter mechanical connection, significantly increases the tightness of the fit between the second shaft end and the insertion blind hole compared to a traditional cylindrical hole structure, thereby improving the transmission accuracy between the second shaft end and the first connecting shaft. Simultaneously, the combination of the polygonal hole and the polygonal structure increases the friction between them, effectively reducing slippage caused by changes in axial or radial loads. Therefore, this connection structure is more suitable for high-torque or high-precision transmission scenarios.

[0295] Of course, in some other embodiments, the blind insertion hole 12002 can also be a regular cylindrical hole, and the second shaft end 12015 is a cylindrical structure that is inserted into the cylindrical hole. By controlling the tightness of the fit between the blind insertion hole 12002 and the second shaft end 12015, the transmission accuracy between the first connecting shaft 12001 and the second shaft end 12015 can also be achieved.

[0296] With the second shaft end 12015 and the first connecting shaft 12001 using a polygonal hole and a polygonal structure for insertion, in order to further improve the stability of power transmission between the first roller 1201 and the drive structure 160, optionally, in one embodiment, please refer to... Figures 77 to 79 Along the axial direction of the first roller 1201, the length of the second shaft end 12015 is greater than the length of the docking end 120241. Furthermore, the length of the driving section of the second shaft end 12015 is greater than the length of the docking end 120421. Let the length of the driving section be defined as A, and the length of the docking end 120421 as B. The ratio of the lengths A and B is 0 < B / A < 1. Preferably, B / A can be 1 / 2, 1 / 3, 1 / 4, etc. With this configuration, during the insertion of the mating end 120241 into the second mounting hole 14121 and the drive segment into the insertion blind hole 12002, because the length of the drive segment of the second shaft end 12015 is greater than the length of the mating end 120241, the drive segment first enters the insertion blind hole 12002 to achieve initial alignment. As the drive segment is about to fully enter the insertion blind hole 12002, the mating end 120241 can quickly enter the second mounting hole 14121 through the alignment of the drive segment, eliminating the need for the user to repeatedly align it. This initial alignment using the drive segment increases the difficulty of aligning the mating end 120241 and the second shaft end 12015 with the base 141, thereby improving installation convenience and enhancing the user experience.

[0297] Meanwhile, since the length of the drive section of the second shaft end 12015 is greater than the length of the docking end 120241, the different lengths of the drive section and docking end 120241 have a foolproof effect during the process of installing the bracket assembly 120 with the cleaning component 110 into the receiving cavity 190. This can prevent the user from installing the bracket assembly 120 with the cleaning component 110 backwards in the receiving cavity 190, thereby increasing the probability that the user can accurately install the bracket assembly 120.

[0298] Furthermore, the length ratio between A and B limits the axial fit length between the second shaft end 12015 and the first connecting shaft 12001. A longer dimension A indicates a larger insertion length of the second shaft end 12015 into the first connecting shaft 12001. Therefore, with the number of sides of the insertion blind hole 12002 remaining constant, a larger contact area between the second shaft end 12015 and the insertion blind hole 12002 on the first connecting shaft 12001 is more beneficial for improving the stability of power transmission between the second shaft end 12015 and the first connecting shaft 12001. Therefore, limiting dimension A prevents the insertion length between the second shaft end 12015 and the first connecting shaft 12001 from being too short, which would affect the stability of power transmission between the first roller 1201 and the first connecting shaft 12001.

[0299] Please see Figure 77 and Figure 78 When the length of the drive section is greater than the length of the docking end 120241, the inclined section 1434 of the abutment portion 1431 includes a first inclined section 14341 and a second inclined section 14342. The angle between the first inclined section 14341 and the vertical plane passing through the axis of the first roller 1201 is greater than the angle between the second inclined section 14342 and the vertical plane passing through the axis of the first roller 1201. The second support seat 12012 is provided with a first docking inclined surface 120126 corresponding to the first inclined section 14341, and the fourth support seat 12024 is provided with a second docking inclined surface 120242 corresponding to the second inclined section 14342. When the abutment portion 1431 is inserted between the second support seat 12012 and the fourth support seat 12024, the first docking inclined surface 120126 is in contact with the first inclined section 14341, and the second docking inclined surface 120242 is in contact with the second inclined section 14342. It should be noted that the first docking inclined surface 120126 and the third guide inclined surface 1204 of the second support 12012 are the same inclined surface, and the second docking inclined surface 120242 and the third guide inclined surface 1204 of the fourth support 12024 are the same inclined surface.

[0300] The length of the first inclined section is greater than the length of the second inclined section. Along the axial direction of the first roller 1201, the distance between the end of the first connecting shaft 12001 away from the base 141 and the end of the second outer support 143 away from the base 141 is less than the distance between the end of the second mounting hole away from the base 141 and the end of the second outer support 143 away from the base 141. The length of the first roller 1201 is less than the length of the second roller 1202, and the end faces of the first roller 1201 and the second roller 1202 away from the base 141 are flush. It should be noted that the first roller 1201 here refers to the roller body excluding the first shaft end 12014 and the second shaft end 12015, and the second roller 1202 refers to the roller body excluding the third shaft end 12025 and the fourth shaft end 12026.

[0301] With this configuration, along the axial direction of the first roller 1201, the width of the portion of the second outer support 143 corresponding to the second support seat 12012 is greater than the width of the portion of the second outer support 143 corresponding to the first support seat. This allows the end of the extended first connecting shaft 12001 away from the seat body 141 to be nearly flush with the end of the first inclined section near the seat body 141, thus providing space for the extension of the first connecting shaft 12001 and the drive section. It also allows for a clearance fit between the second support seat 12012 and the end face of the first connecting shaft 12001 away from the seat body 141, achieving a compact structure.

[0302] Considering the connection efficiency between the second support 12012 and the first bracket 121, optionally, in one embodiment, please refer to... Figure 72 The second support 12012 is snap-fitted to the first bracket 121. There are various snap-fit ​​connection methods, such as a slot and block snap-fit ​​structure. A slot is provided on one of the first bracket 121 and the second support 12012, and a matching block is provided on the other. The block is typically designed as a protrusion, while the slot is recessed; the two achieve snap-fit ​​through their shapes. Alternatively, it can be a snap-fit ​​structure using an elastic buckle and a snap-fit ​​boss or groove. An elastic buckle is provided on one of the first bracket 121 and the second support 12012, and a corresponding snap-fit ​​boss or groove is provided on the other. The elastic buckle deforms and snaps into the corresponding boss or groove, using elastic restoring force to achieve snap-fit ​​fixation. By snap-fitting the second support 12012 to the first bracket 121, the assembly process is simplified, eliminating the need for additional fasteners, thereby improving the connection efficiency between the second support 12012 and the first bracket 121, and reducing assembly time and operational complexity.

[0303] Specifically, in this embodiment, please refer to Figures 73 to 76The bracket body is provided with a first mating part 1218. Specifically, the first mating part 1218 is disposed on the first bracket 121 and extends along the length direction of the first bracket 121. The second support base 12012 is provided with a first mating groove 120121, which matches the shape of the first mating part 1218. The first mating part 1218 can be slidably inserted into the first mating groove 120121 along the length direction of the first bracket 121, and the first mating part 1218 and the first mating groove 120121 are connected in the length direction of the first bracket 121. The first mating groove 120121 includes two oppositely disposed groove sidewalls 120122 and a groove bottom wall 120123 connecting the two groove sidewalls 120122. When the first mating part 1218 is inserted into the first mating groove 120121, the two groove side walls 120122 abut against the two side surfaces of the first mating part 1218 respectively, and the groove bottom wall 120123 abuts against the bottom surface of the first mating part 1218, so as to achieve precise insertion and positioning of the second support 12012 in the width and height directions of the first bracket 121, ensuring the stability and reliability of the connection.

[0304] By setting a first mating part 1218 and a first mating groove 120121, and slidably inserting the first mating part 1218 into the first mating groove 120121, not only can the accuracy and stability of the assembly between the first bracket 121 and the second support base 12012 be ensured, but the connection efficiency can also be improved, facilitating the installation and disassembly of the second support base 12012 and the first bracket 121. Simultaneously, since the first mating part 1218 slides into the first mating groove 120121 along the length of the first bracket 121, when the first roller 1201 needs to be installed onto the first bracket 121, the first shaft end 12014 can be inserted into the first support base 12011 first, and then the second shaft end 12015 can be inserted into the second support base 12012 along the axial direction of the first roller 1201. Furthermore, during the insertion process, the insertion between the first mating groove 120121 and the first mating part 1218 can be completed simultaneously. This operation simplifies assembly steps, saves assembly time, and improves the overall assembly efficiency.

[0305] Alternatively, in one embodiment, please continue to refer to Figures 73 to 76The second support base 12012 also includes a second mating groove 120124, which penetrates the bottom wall 120123. A third buckle 120125 is provided on the side wall of the second mating groove 120124. It should be noted that the third buckle 120126 can be provided on only one side wall of the second mating groove 120124, or it can be provided on both side walls. Optionally, in this embodiment, the third buckle 120126 is provided on both side walls. The bracket body is also provided with a second mating part 1219. Specifically, the second mating part 1219 is provided on the first bracket 121 and is connected to the first mating part 1218. A first groove 12192 matching the third buckle 120126 is provided on the side wall of the second mating part 1219. When the second support 12012 is inserted into the first bracket 121, that is, when the first mating part 1218 is inserted into the first mating groove 120121, the third buckle 120126 on each side is correspondingly snapped into the first groove 12192 on the same side, so as to limit and fix the connection between the second support 12012 and the bracket body.

[0306] With this configuration, when the second support 12012 is inserted into the first bracket 121, the third buckle 120126 and the first groove 12192 engage with each other. This can further improve the positioning and connection of the second support 12012 in the length direction of the first bracket 121, which is beneficial to improving the stability of the insertion of the second support 12012 into the first bracket 121.

[0307] Optionally, in one embodiment of this utility model, please refer to Figures 73 to 76The first support 121 has a clearance arc surface 12193 on the side facing the first roller 1201, which is adapted to the outer peripheral surface of the first roller 1201. Two notches 12194 are provided at the end of the clearance arc surface 12193 near the second support base 12012, located on opposite sides of the clearance arc surface 12193 in the radial direction. Two transition arc surfaces 12195 are provided at the end of the second support base 12012 facing the first support 121, each matching one of the two notches 12194. When the second support base 12012 is inserted into the first support 121, the two transition arc surfaces 12195 fill the two notches 12194, forming an arc connection with the clearance arc surface 12193. This design, by avoiding the interaction of the curved surface 12193, the notch 12194, and the transition curved surface 12195, ensures that the first roller 1201 will not interfere with the second support 12012 and the first bracket 121 during rotation. Simultaneously, when the second support 12012 is inserted into the first bracket 121, the interaction between the transition curved surface 121965 and the notch 12194 allows for a smooth transition, improving the overall structural compactness and aesthetics.

[0308] It should be noted that the insertion structure between the fourth support 12024 and the second bracket 122 is the same as the insertion structure between the second support 12012 and the first bracket 121 in the above embodiment, and will not be described again here.

[0309] To improve the cleaning effect of the cleaning component 110 and reduce its replacement frequency, optionally, in one embodiment of this utility model, please refer to... Figure 30 and Figure 31 The cleaning assembly 100 also includes a fluffing roller 170, which is rotatably mounted within the receiving cavity 190 and makes interference contact with the outer surface of the cleaning component 110. The fluffing roller 170 is arranged parallel to the first roller 1201 and the second roller 1202. The fluffing roller 170 includes a roller shaft 171 and a fluffing hook 172. The connecting end of the fluffing hook 172 is fixed to the roller shaft 171, which is arranged along the length direction of the cleaning component 110. The free end of the fluffing hook 172 is curved. The curvature direction of the free end of the fluffing hook 172 is the same as the rotation of the roller shaft 171, which makes it easier to lift the lint on the surface of the rotating cleaning component 110, so that the cleaning component 110 remains fluffy during the cleaning process, thereby improving the cleaning effect.

[0310] Please see Figure 80 , Figure 81 , Figure 82 and Figure 87The roller shaft 171 of the fluffing roller 170 includes a first support end 173 and a second support end 174. The first support end 173 is disposed at the end of the roller shaft 171 facing away from the base 141 and is rotatably connected to the housing 180. The first support end 173 can be directly rotatably connected to the housing 180, or it can be indirectly rotatably connected to the housing 180 through other parts. Optionally, in this embodiment, please refer to... Figures 83 to 86 The fluffing stick 170 also includes a connector 175, which is disposed within the receiving cavity 190 and fixedly connected to the housing 180. The connector 175 has a mounting hole 1751, in which a sixth bearing 12008 is installed. The first support end 173 is a rotating shaft structure, and the first support end 173 is interference-fitted with the sixth bearing 12008, thereby realizing the rotational connection of the first support end 173 relative to the housing 180.

[0311] Please see Figure 88 The gear assembly 162 includes a third gear structure 1625. A second gear 16232 on the output shaft of the first gear structure 1623 is connected to the third gear structure 1625. When the first gear structure 1623 rotates, it not only drives the second gear structure 1624 to rotate, but also drives the third gear structure 1625 to rotate. The output end of the third gear structure 1625 forms the second output end 1622 of the gear assembly 1622, and the second output end 1622 is equipped with a second output gear 16221. The third gear structure 1625 is a gear train structure.

[0312] Please see Figure 87 The second support end 174 is located at one end of the roller 171 near the base 141 and is fixedly connected to the second output gear 16221. Specifically, the fluffing roller 170 also includes a transition shaft 176, and the base 141 also includes a third mounting hole 1410. The transition shaft 176 is rotatably connected to the third mounting hole 1410 via a seventh bearing 12009. One end of the transition shaft 176 extends to the outside of the receiving cavity 190 and is fixedly connected to the second output gear 16221. The other end of the transition shaft 176 extends to the inside of the receiving cavity 190 and is provided with a first blind hole 1761. The first blind hole 1761 is a polygonal hole structure, such as a quadrilateral hole, a hexagonal hole, an octagonal hole, etc. The second support end 174 is a polygonal structure corresponding to the first blind hole 1761. The second support end 174 is inserted into the first blind hole 1761 to achieve a fixed connection between the second support end 174 and the adapter shaft 176, thereby achieving a fixed connection between the roller shaft 171 and the second output gear 16221. When the first driving member 161 rotates, it drives the second output gear 16221 to rotate, and the rotation of the second output gear 16221 drives the second support end 174 to rotate, thereby driving the fluffing roller 170 to rotate relative to the housing 180.

[0313] The length of the fluffing roller 170 is greater than or equal to the length of the cleaning part 110, so that the fluffing roller 170 can cover the cleaning part 110 in the length direction of the cleaning part, so that the entire working area of ​​the cleaning part 110 can be fluffed by the fluffing roller 170.

[0314] Of course, in other embodiments, the length of the fluffing roller 170 may only cover a portion of the length of the cleaning component 110, which can also achieve the effect of local fluffing.

[0315] By incorporating the fluffing roller 170, the cleaning component 100 can be fluffed during cleaning operations, thereby ensuring the cleaning component 100 remains in a highly efficient cleaning state and improving its cleaning efficiency. Furthermore, by using the same motor to simultaneously drive both the cleaning component 100 and the fluffing roller 170, assembly space is saved, and the production cost of the cleaning component 100 is reduced.

[0316] To facilitate the assembly and disassembly of the fluffing roller 170 and the housing 180, alternatively, in another embodiment of this utility model, please refer to... Figures 83 to 86 The connector 175 is snapped into the housing 180. Specifically, the connector 175 includes a hook portion 1752 and a protrusion portion 1753, which are angled and positioned around the outer periphery of the mounting hole 1751. The housing 180 includes a hook groove 1804 and a recessed portion 1805. The hook groove 1804 extends along the rotation direction of the fluffing roller 170. The hook portion 1752 matches the hook groove 1804, and the protrusion portion 1753 matches the recessed portion 1805. When installing the connector 175, the hook portion 1752 is first snapped into the hook groove 1804, and then the connector 175 is rotated along the hook groove 1804 so that the protrusion portion 1753 is correspondingly snapped into the recessed portion 1805, thereby achieving a snap-fit ​​connection between the connector 175 and the housing 180. This configuration not only enables a stable and reliable snap-fit ​​connection between the connector 175 and the housing 180, but also simplifies the installation process and improves the assembly efficiency between the fluffing roller 170 and the housing 180, since no additional connecting parts are required.

[0317] It should be noted that the rotation direction of the fluffing roller 170 can be the same as or opposite to the rotation direction of the cleaning component 110. Optionally, in this embodiment, the rotation direction of the fluffing roller 170 is different from the rotation direction of the cleaning component 110. With this configuration, when the free end of the fluffing roller 170 moves relative to the cleaning component 110, it is easier to flip the cleaning component 110, which is beneficial to improving the fluffing effect of the cleaning component 110.

[0318] While satisfying the requirements of the transmission torque and transmission ratio of the second gear structure 1624 and the third gear structure 1625, the number of gears in the second gear structure 1624 and the third gear structure 1625 is not limited. Optionally, in one embodiment of this utility model, please refer to... Figure 88 The second gear structure 1624 has a greater number of gears than the third gear structure 1625. This configuration allows for different output speeds and torques at the first input end 1621 and the second output end 1622, thus better meeting the torque and speed requirements of the first roller 1201 and the fluffing roller 170.

[0319] To achieve a different rotation direction between the fluffing roller 170 and the cleaning component 110, optionally, in one embodiment, please refer to... Figure 88 In this configuration, one of the second gear structure 1624 and the third gear structure 1625 has an odd number of gears, while the other has an even number of gears. For example, the second gear structure 1624 can have an odd number of gears, and the third gear structure 1625 can have an even number of gears. Alternatively, the second gear structure 1624 can have an even number of gears, and the third gear structure 1625 can have an odd number of gears. This configuration allows for different rotation directions at the output ends of the second gear structure 1624 and the third gear structure 1625, i.e., different rotation directions at the first output end 1621 and the second output end 1622, thereby allowing for different rotation directions between the fluffing roller 170 and the cleaning component 110.

[0320] Under the condition that the drive structure 160 drives the first roller 1201 to rotate, optionally, in one embodiment of this utility model, please refer to... Figure 53 The outer circumferential surface of the first roller 1201 at the contact position with the cleaning component 110 is made of rubber. This design reduces slippage between the cleaning component 110 and the first roller 1201 due to the high coefficient of friction of the rubber material, ensuring that the cleaning component 110 can rotate stably with the first roller 1201, thereby improving the cleaning effect.

[0321] Optionally, please refer to Figure 53In one embodiment of this utility model, the first roller 1201 includes a first active roller 120001 and a second active roller 120002, which are respectively disposed at both ends of the supporting section 1203 of the first roller 1201. In one embodiment, the first active roller 120001 and the second active roller 120002 can be two independently disposed shaft segments, which can be detachably connected by couplings, bearing seats, etc. This allows for flexible preparation of the weight of the first active roller 120001 and the second active roller 120002 according to the requirements of gravity distribution, thus making the design more flexible. In another embodiment, the first active roller 120001 and the second active roller 120002 can also share a common inner core and be non-detachable from each other. This facilitates the assembly of the first roller 1201 and improves assembly efficiency.

[0322] Similarly, the second roller 1202 also includes a first driven roller 120003 and a second driven roller 120004, which are respectively disposed at both ends of the supporting section 1203 of the second roller 1202. In one embodiment, the first driven roller 120003 and the second driven roller 120004 can be two independently disposed shaft segments, which can be detachably connected by couplings, bearing seats, etc. This allows for flexible preparation of the weight of the first driven roller 120003 and the second driven roller 120004 according to the requirements of gravity distribution, thus making the design more flexible. In another embodiment, the first driven roller 120003 and the second driven roller 120004 can also share a common inner core and be non-detachable from each other. This facilitates the assembly of the second roller 1202 and improves assembly efficiency.

[0323] Optionally, in this embodiment, please refer to Figure 55The first roller 1201 includes a first inner core 120005, which is made of metal. The first inner core 120005 is covered by an outer layer, which includes a first outer layer 120051 and a second outer layer 120052. The first outer layer 120051 and the corresponding position of the first inner core 12005 form a first active roller 120001, and the second outer layer 120052 and the corresponding position of the first inner core 12005 form a second active roller 120002. Both the first outer layer 120051 and the second outer layer 120052 are made of a soft rubber material, such as silicone or rubber. It should be noted that, in order to facilitate the molding of the first outer layer 120051 and the second outer layer 120052 onto the first inner core 12005, shaping components (not shown in the figure) are provided at both ends of the first outer layer 120051 and both ends of the second outer layer 120052. These shaping components are made of hard rubber. The hard rubber material can be polyvinyl chloride, polypropylene, etc. This arrangement allows the first and second outer layers 120051 and 120052, made of soft rubber material, to have greater friction, improving the transmission stability between the cleaning component 110 and the first and second drive rollers 120001 and 120002. Furthermore, it also reduces the manufacturing cost and overall weight of the first roller 1201.

[0324] Of course, in other embodiments, the materials of the first outer layer 120051 and the second outer layer 120052 can also be hard plastic or metal, as long as they can drive the cleaning component 110 to rotate when the first roller 1201 rotates, so that the cleaning component 100 can perform normal cleaning operations.

[0325] Considering that the cleaning component 100 has a drive structure 160 and a base 141 at one end near the base 141, this will cause a weight deviation at both ends of the cleaning component 100 in the length direction. During cleaning operations, this will result in uneven cleaning forces between the cleaning component 110 and the surface to be cleaned, affecting the uniformity of the cleaning effect. Therefore, optionally, in one embodiment of this utility model, please refer to... Figure 31 and Figure 56The second roller 1202 includes a second inner core 12006, which is made of metal and is integrally formed between the third shaft end 12025 and the fourth shaft end 12026. The second inner core 120006 is covered with an outer layer, which includes a third outer layer 120061 and a fourth outer layer 120062. The fourth outer layer 120062 is located at the end of the second roller 1202 away from the base 141. The third outer layer 120061 and the corresponding position of the second inner core 12006 form a first driven roller 120003, and the fourth outer layer 120062 and the corresponding position of the second inner core 12006 form a second driven roller 120004. The third outer layer 120061 is made of a soft rubber material, such as silicone or rubber. The fourth outer cladding layer 120062 is made of metal. The fourth outer cladding layer 120062 can be made of the same metal as the second inner core 12006, or it can be made of a different type of metal. This embodiment does not limit this.

[0326] It should be noted that, to facilitate the molding of the third outer layer 120061 onto the second inner core 12006, shaping components are also provided at both ends of the third outer layer 120061. These shaping components are made of hard rubber. The hard rubber material can be polyvinyl chloride, polypropylene, etc. This design allows the third outer layer 120061, made of soft rubber material, to have greater friction, ensuring sufficient transmission friction between the second roller 1202 and the cleaning component 110, reducing the probability of slippage between them, and improving the stability of the cleaning component 110's transmission. On the other hand, since the fourth outer layer 120062 is made of metal, under the same diameter and length conditions, the mass of the second driven roller 120004 is greater than the mass of the first driven roller 120003. This can increase the weight of the second roller 1202 at the end away from the seat 141, which is beneficial to improve the weight deviation at both ends of the cleaning component 100 in the length direction, and improve the overall stability of the cleaning component 100 and the consistency of the cleaning effect.

[0327] In order to improve the stability of the first roller 1201 and the second roller 1202 when driving the cleaning component 110 to rotate, and in order to improve the flatness of the cleaning component 110 facing the ground, the outer diameter of the outer layer on the first inner core 120005 and the outer diameter of the outer layer on the second inner core 120006 are equal.

[0328] To further improve the weight deviation generated by the cleaning component 100, alternatively, in another embodiment of this invention, please refer to... Figure 89The cleaning assembly 100 also includes a counterweight 1806, which is disposed at the end of the housing 180 away from the drive mechanism 160. The counterweight 1806 may be disposed on the side of the housing 180 facing the cleaning component 110 or on the side of the housing 180 away from the cleaning component 110.

[0329] Optionally, in this embodiment, the counterweight 1806 is disposed on the side of the housing 180 away from the cleaning component 110, i.e., on the outer side of the housing 180. This arrangement facilitates the installation of the counterweight 1806 on the housing 180. The counterweight 1806 can be snap-fitted to the housing 180 or fixed to the housing 180 by bolts. Optionally, in this embodiment, the counterweight 1806 is fixed to the housing 180 by bolts. The counterweight 1806 can be made of metal or non-metal, as long as it meets the counterweight requirements, there is no limitation. By disposing of the counterweight 1806 at the end of the housing 180 away from the base 141, the weight of the cleaning component 100 at the end away from the drive mechanism 160 can be increased, thereby further improving the problem of uneven weight distribution caused by the installation of the drive structure 160 at the end of the base 141. Therefore, this design can balance the overall center of gravity of the cleaning component 100, reduce vibration and offset during operation, and further improve the overall stability of the cleaning component 100 and the consistency of the cleaning effect.

[0330] Provided that the counterweight requirements of counterweight 1806 are met, the specific location and quantity of counterweight 1806 are not limited. Optionally, please refer to [link / reference needed]. Figure 89 and Figure 164 In one embodiment, the counterweight 1806 includes a first counterweight 18061, which can be a plate-like structure, a block-like structure, a column-like structure, etc. In this embodiment, the first counterweight 18061 is a plate-like structure. The first counterweight 18061 is disposed at the end of the housing 180 away from the drive mechanism 160 and covers the clearance groove 1802 of the housing 180. With this arrangement, the first counterweight 18061 can not only play a good counterweight role, but also act as a cover plate to cover the clearance groove 1802 structure on the housing 180, thereby improving the aesthetics of the overall structure.

[0331] Please see Figure 165In another embodiment, the counterweight 1806 includes a first counterweight 18061, a second counterweight 18062, and a third counterweight 18063. The second and third counterweights 18062 and 18063 are disposed on the side of the first counterweight 18061 facing the drive mechanism 160, and are close to the first counterweight 18061. The second and third counterweights 18062 and 18063 are arranged along the width of the housing 180. The entire structure formed by the first, second, and third counterweights 18061 is located at the end of the housing 180 away from the drive mechanism 160. The mass of the second and third counterweights 18062 and 18063 can be the same or different; in actual design, this needs to be determined based on the overall mass balance requirements of the cleaning assembly 100.

[0332] By setting the first counterweight 18061, the second counterweight 18062, and the third counterweight 18063, a distributed layout of the counterweight mass on the housing 180 can be achieved, thereby more flexibly optimizing the overall counterweight performance of the cleaning component 100. Simultaneously, by precisely controlling the mass distribution of each counterweight 1806, various counterweight combination schemes can be formed, allowing for precise adjustment of vibration characteristics under different operating conditions, significantly improving the adjustability and optimization efficiency of the dynamic balance of the cleaning component 100.

[0333] Please see Figures 90 to 118 In one embodiment of the present invention, a cleaning component 100 is also provided, which includes a first connector 301, a second connector 302, and a cleaning mechanism 303.

[0334] The first connector 301 is detachably connected to the bottom of the body 200 to achieve a detachable connection between the cleaning component 100 and the body 200. The detachable connection method can be a bolt-on detachable connection or a snap-fit ​​detachable connection, etc. Specifically, in this embodiment, please refer to... Figures 90 to 93The body 200 includes a base 250, which has a cleaning component mounting cavity 260 for accommodating the cleaning component 100. The upper wall of the cleaning component mounting cavity 260 has multiple mounting slots 261 and multiple mounting through holes 262. The first connector 301 has multiple mounting screw holes 3016 and multiple mounting clips 3017 extending towards the base 250. The multiple mounting screw holes 3016 correspond one-to-one with the multiple mounting through holes 262 for mounting fasteners, such as bolts and screws, from the base 250. The multiple mounting slots 261 correspond one-to-one with the multiple mounting clips 3017, and the mounting clips 3017 engage with the mounting slots 261 to form a pre-installed relationship between the first connector 301 and the base 250, facilitating the subsequent installation of fasteners in the mounting through holes 262 and mounting screw holes 3016.

[0335] Please see Figure 94 The second connector 302 is slidably mounted on the first connector 301. There are several possible sliding mounting methods. For example, one of the first connector 301 and the second connector 302 can be provided with a sliding groove, and the other with a sliding block. The sliding connection between the second connector 302 and the first connector 301 is achieved through the cooperation of the sliding groove and the sliding block. Alternatively, one of the first connector 301 and the second connector 302 can be provided with a guide rod, and the other with a guide sleeve. The sliding connection between the second connector 302 and the first connector 301 is achieved through the cooperation of the guide rod and the guide sleeve.

[0336] Please see Figures 94 to 96 The cleaning mechanism 303 is movably mounted on the second connector 302, and has a raised position and a mopping position. It should be noted that the cleaning mechanism 303 may also include all the components on the cleaning assembly 100 in the above embodiments, such as the cleaning component 110, the support assembly 120, the pulling component 130, the external support assembly 140, and other components mounted on the external support assembly 140 and the support assembly 120. However, those skilled in the art will understand that in some other embodiments, the external support assembly 140 may not be present, and a conventional tensioning structure for the cleaning component 110 may be used instead.

[0337] Please see Figure 97 A lifting mechanism 304 is provided between the cleaning mechanism 303 and the second connecting member 302. During the sliding process of the second connecting member 302 relative to the first connecting member 301, the lifting mechanism 304 drives the cleaning mechanism 303 to perform lifting and lowering movements, so that the cleaning mechanism 303 is in a raised position or a mopping position. For example, as... Figure 40 As shown, when the cleaning component 100 is in the mopping state, the cleaning mechanism 303 descends and contacts the ground under the action of the lifting mechanism 304 to clean the ground; that is, the cleaning mechanism 303 is in the mopping position. Another example is... Figure 39 As shown, when the cleaning component 100 moves to the cleaning area, the cleaning mechanism 303 is raised by the lifting mechanism 304 and keeps a distance from the ground, that is, the cleaning mechanism 303 is in the raised position.

[0338] It should be noted that, in this embodiment, the sliding direction of the second connecting member 302 and the first connecting member 301 is a horizontal direction perpendicular to the lifting direction of the cleaning mechanism 303. The lifting direction of the cleaning mechanism 303 is the height direction of the cleaning assembly 100, such as... Figure 96 As shown on the Z1 axis. The specific sliding direction of the second connecting member 302 relative to the first connecting member 301 is not limited. For example, it can slide along the length direction of the cleaning mechanism 303 or along the width direction of the cleaning mechanism 303. Optionally, in this embodiment, the second connecting member 302 slides horizontally relative to the first connecting member 301 along the length direction of the cleaning mechanism 303. The sliding direction of the second connecting member 302 is as follows: Figure 96 As shown on the X1 axis. Simultaneously, the sliding direction of the second connector 302 is also along its length. This effectively utilizes the length of the cleaning mechanism 303, reducing the width of the cleaning component 100 occupied by the second connector 302 during sliding, thus promoting a more compact structural design.

[0339] The lifting mechanism 304 can be a sloped surface and slider structure. A sloped surface is provided on one of the second connecting member 302 and the cleaning mechanism 303, and a slider is provided on the other. During the sliding of the second connecting member 302 relative to the first connecting member 301, the slider slides along the sloped surface, thereby achieving the lifting and lowering of the cleaning mechanism 303 along the second connecting member 302. Alternatively, the lifting mechanism 304 can be a rope and pulley structure. A pulley is provided on the first connecting member 301, one end of the rope is connected to the cleaning mechanism 303 below the pulley, and the other end is connected to the second connecting member 302 via the pulley. During the horizontal sliding of the second connecting member 302 relative to the first connecting member 301, the second connecting member 302 pulls the rope up and down along the pulley, thereby driving the cleaning mechanism 303 connected to the rope to perform lifting and lowering movements.

[0340] The cleaning component 100 of this invention features a lifting mechanism 304. During the sliding motion of the second connecting member 302 relative to the first connecting member 301, the lifting mechanism 304 drives the cleaning mechanism 303 to move up and down, allowing the cleaning mechanism 303 to switch between a raised and mopping position. This design, on the one hand, allows the cleaning component 100 to better meet various application scenarios because the lifting mechanism 304 can drive the cleaning mechanism 303 to move up and down. For example, during cleaning operations, when the machine body 200 passes over a carpet, the cleaning mechanism 303 can be switched to the raised position to avoid wetting the carpet; or, in scenarios requiring obstacle crossing or returning to a base station, the cleaning mechanism 303 can also be switched to the raised position to prevent it from being stuck by obstacles and detaching from the machine body 200. On the other hand, since the lifting mechanism 304 can drive the cleaning mechanism 303 to move up and down during the sliding of the second connector 302 relative to the first connector 301, the lifting mechanism 304 can be directly driven to run by the sliding of the second connector 302 without the need for an additional independent lifting motor or hydraulic system. Therefore, the equipment structure can be simplified and the overall weight of the cleaning component 100 can be reduced.

[0341] Please see Figures 97 to 100 In one embodiment of this utility model, the lifting mechanism 304 includes a lifting surface 3041 and a supporting portion 3042. The lifting surface 3041 is disposed on the second connecting member 302, and the supporting portion 3042 is disposed on the side of the cleaning mechanism 303 facing the first connecting member 301. The lifting surface 3041 is supported below the supporting portion 3042, and the supporting portion 3042 is pressed against the lifting surface 3041 by the gravity of the cleaning mechanism 303. The supporting portion 1431 moves along the lifting surface 3041, driving the cleaning mechanism 303 to achieve lifting movement.

[0342] The number of lifting surfaces 3041 and supporting parts 3042 can be set according to actual needs, but in this embodiment, please refer to Figure 94 , Figure 97 and Figure 98 To improve the stability and lifting accuracy of the cleaning mechanism 303, two abutment portions 3042 are spaced apart in the middle area of ​​the cleaning mechanism 303 along its length. Two lifting surfaces 3041 are correspondingly provided on the second connecting member 302, and the inclination directions of the two lifting surfaces 3041 are consistent. To facilitate the forming and positioning of the two lifting surfaces 3041, in this embodiment, the two lifting surfaces 3041 are positioned along the second connecting member 302 (e.g., ...). Figure 102The cleaning mechanism 303 is arranged in a length-direction array (as shown by the X2 axis) on the second connector 302. Two abutment portions 3042 respectively abut against two lifting surfaces 3041, thus forming two lifting points along the length of the cleaning mechanism 303. This arrangement effectively distributes the weight of the cleaning mechanism 303 during lifting because the two lifting points work together, preventing tilting or swaying caused by single-point force, thereby significantly improving the stability of the lifting motion.

[0343] The lifting surface 3041 and the contact portion 1431 can have various design forms. For example, the lifting surface 3041 can be an inclined surface, an arc surface, or a combination of inclined and arc surfaces. The contact portion 3042 can be a structure such as an inclined block, an arc block, or a pin connected to the cleaning mechanism 303. When the contact portion 3042 moves along the lifting surface 3041, the contact between the contact portion 3042 and the lifting surface 3041 can be rolling contact or sliding contact; this embodiment is not limited to either.

[0344] By setting up a lifting surface 3041 and a supporting part 3042, the lifting function of the cleaning mechanism 303 can be realized through the abutting cooperation between the lifting surface 3041 and the supporting part 3042. This structure is simple in design and easy to manufacture. At the same time, since the supporting part 3042 is pressed against the lifting surface 3041 by the gravity of the cleaning mechanism 303, this design allows the lifting mechanism 304 to achieve self-locking by the gravity of the cleaning mechanism 303 in the non-driven state, preventing the cleaning mechanism 303 from accidentally sliding or falling, thereby improving the stability of the lifting operation of the cleaning mechanism 303. Furthermore, the gravity pressing design can also ensure a tight contact between the supporting part 3042 and the lifting surface 3041, maintaining a stable abutment even under changes in the load of the cleaning mechanism 303, avoiding slippage or vibration of the cleaning mechanism 303 due to poor contact, which would affect the cleaning operation.

[0345] Optionally, in one example of this utility model, please refer to Figure 97 and Figure 100 The second connector 302 includes a recess 3021, which is recessed on one side facing the cleaning mechanism 303. A protruding structure 3022 is provided inside the recess 3021, connecting one side wall of the recess 3021 along its length to the bottom wall of the recess 3021. The length direction of the recess 3021 is consistent with the length direction of the second connector 302. A lifting surface 3041 is formed on the outer surface of the protruding structure 3022.

[0346] Please see Figure 101 , Figure 102 and Figure 103The bottom wall of the recessed cavity 3021 is provided with two first through grooves 3023. Along the width direction of the recessed cavity 3021, the two first through grooves 3023 are respectively located on both sides of the protruding structure 3022, and both extend along the length direction of the recessed cavity 3021. The width direction of the recessed cavity 3021 is the same as the width direction of the second connecting member 302 (e.g., ...). Figure 102 (As shown on the Y2 axis). Please refer to [link / reference]. Figure 100 and Figure 103 The cleaning mechanism 303 has two sets of connecting ends 3015 on the side facing the first connector 301. Each set of connecting ends 3015 is connected to a supporting part 3042, and each set of connecting ends 3015 includes two extensions 3011. One end of each extension 3011 is connected to the side of the cleaning mechanism 303 facing the first connector 301. Specifically, both extensions 3011 are provided on the housing 180. Each extension 3011 corresponds to a first through groove 3023, and the extension 3011 is slidably installed in the first through groove 3023 and extends at least partially into the cavity 3021. The supporting part 3042 is installed above the lifting surface 3041. Along the width direction of the cavity 3021, both ends of the supporting part 3042 are connected to the extensions 3011 on both sides, thereby realizing the connection between the supporting part 3042 and the cleaning mechanism 303. When the supporting part 3042 moves along the lifting surface 3041, the two extension parts 3011 slide along the first through groove 3023 at the corresponding positions.

[0347] Since the protruding structure 3022 connects the sidewall and bottom wall of the recessed cavity 3021, and the lifting surface 3041 is formed on the outer surface of the protruding structure 3022, this structure can improve the local support strength and rigidity of the lifting surface 3041, thereby providing stable and reliable support for the supporting part 3042, ensuring that the lifting surface 3041 has good support stability during long-term use. Simultaneously, the two side extensions 3011 are connected to both ends of the supporting part 3042, forming a double-point connection structure that balances the force on the supporting part 3042, preventing stress concentration on one side and deformation, further improving the contact stability between the supporting part 3042 and the lifting surface 3041. Furthermore, the cooperation between the extensions 3011 and the first through groove 3023 can also provide initial guidance when the lifting surface 3041 and the supporting part 3042 move relative to each other, thus improving the smoothness of the lifting process of the cleaning mechanism 303 and reducing the probability of deviation or shaking.

[0348] Optionally, in one example of this utility model, please refer to Figure 100 , Figure 101 Figure 104The lifting surface 3041 includes an inclined surface 30411. Along the depth direction of the cavity 3021, the inclined surface 30411 slopes from the bottom wall of the cavity 3021 toward the opening side of the cavity 3021. The inclination angle of the inclined surface 30411 is determined by the lifting distance of the cleaning mechanism 303. See also... Figure 103 The supporting part 3042 is a pin, which is fixedly connected to the cleaning mechanism 303. Both extensions 3011 are provided with pin mounting holes 30111, and both ends of the pin are respectively installed in the corresponding pin mounting holes 30111. The pin and the pin mounting holes 30111 are fixedly connected, including but not limited to, through an interference fit between the pin and the hole. The outer circumferential surface of the pin abuts against the inclined surface 30411 and slides along the lifting surface 3041.

[0349] In this embodiment, a sloping lifting surface 3041 is used. This allows for adjustment of the lifting stroke of the cleaning mechanism 303 simply by adjusting the inclination angle of the sloping surface 30411, thus providing good design adaptability and making it easier to match various cleaning mechanisms 303 with different lifting stroke requirements. Simultaneously, the supporting part 3042 is configured as a pin and fixedly connected to the cleaning mechanism 303. This effectively reduces the frictional force generated when the pin and the lifting surface 3041 move relative to each other, facilitating sliding between them. Furthermore, since the pin does not need to rotate, the connection structure between it and the cleaning mechanism 303 is simpler, which helps reduce the assembly and manufacturing costs of the cleaning component 100.

[0350] In one embodiment, the pin can also be rotatably connected to the cleaning mechanism 303. For example, a bearing can be provided in the pin mounting hole 30111 of the extension 3011, and both ends of the pin can be connected to the pin mounting hole 30111 through the bearing, thereby realizing the rotatable connection between the pin and the cleaning mechanism 303. With this configuration, when the pin moves along the inclined surface 30411, there is rolling friction between them, which can reduce the friction between them and help reduce the energy consumption of the cleaning mechanism 303 during lifting and lowering, thus achieving energy saving. At the same time, it can also reduce the wear between the pin and the inclined surface 30411, which can help improve the service life of the pin and the inclined surface 30411.

[0351] In another embodiment, the pin can also consist of a pin body and a bearing sleeved on the outer periphery of the pin body. The pin is fixedly connected to the pin mounting hole, and the bearing is rotatably connected to the pin body. The pin makes rolling contact with the inclined surface through the bearing. This can also achieve rolling friction between the pin and the inclined surface, reducing the frictional force between the pin and the inclined surface.

[0352] Alternatively, in one embodiment, please refer to Figure 107A raised slide bar 3043 is provided on the inclined surface 30411, and the outer peripheral surface of the pin abuts against the surface of the slide bar 3043. The number of slide bars 3043 is not limited; optionally, in this embodiment, two slide bars 3043 are provided on the inclined surface 30411, and the slide bars 3043 are located on both sides of the width direction of the inclined surface 30411. This arrangement reduces the contact area between the pin and the inclined surface 30411, thereby reducing the frictional resistance between them and making the sliding of the pin smoother.

[0353] To reduce the probability of the pin coming out of the pin mounting hole, optionally, please refer to Figure 108 In one embodiment of this utility model, a first mating hole 3018 is provided on the side wall of the first connector 301, and a second mating hole 3024 is provided on the side wall of the second connector 302. The first mating hole 3018 and the second mating hole 3024 are located on the same side in the width direction of the first connector 301. When the pin is located at a designated position on the inclined surface 30411, the first mating hole 3018, the second mating hole 3024, and the pin mounting hole 30111 are aligned and interconnected to enable the pin to be installed and removed along its own axial direction. When the pin is located at a designated position on the inclined surface 30411, the cleaning mechanism 303 is in a transition position between the rising position and the mopping position. With this configuration, during the operation of the cleaning assembly 100, since the cleaning mechanism 303 spends most of its time in the mopping position and the rising position, the time that the cleaning mechanism 303 spends in the transition position other than the mopping position and the rising position is short, so the pin will almost never stay in the designated position on the inclined surface 30411 for a long time. This design effectively reduces the probability of the pin coming out of the pin mounting hole 30111 during operation, thereby improving the stability and reliability of the overall structural connection.

[0354] Optionally, in one embodiment of this utility model, please refer to Figure 100 and Figure 104 The lifting surface 3041 also includes a first plane 30412 and a second plane 30413, which are respectively connected to the two ends of the inclined plane 30411 in the direction of inclination. The first plane 30412 and the second plane 30413 are arranged in parallel, and the first plane 30412 is located on the side of the inclined plane 30411 closer to the cleaning mechanism 303. The distance of the first plane 30412 from the ground is less than the distance of the second plane 30413 from the ground. When the cleaning mechanism 303 is in the raised position, the abutting part 3042 is held on the second plane 30413, and when the cleaning mechanism 303 is in the lowered position, the abutting part is held on the first plane 30412. Figure 100 As shown, when the cleaning mechanism 303 is in the mopping position, the supporting part 3042 abuts against the first plane 30412. Figure 98As shown, when the cleaning mechanism 303 is in the raised position, the supporting part 3042 abuts against the second plane 30413.

[0355] Specifically, please refer to Figure 104 The first plane 30412 is formed on the bottom wall of the cavity 3021. One end of the first plane 30412 is connected to one side of the wall of the cavity 3021 along its length, and the other end is connected to the end of the inclined plane 30411 near the cleaning mechanism 303 in the inclined direction. One end of the second plane 30413 is connected to the other end of the inclined plane 30411 in the inclined direction, and the other end of the second plane 30413 is connected to the other side wall of the cavity 3021 along its length.

[0356] It should be noted that, as Figure 100 As shown, when the abutting part 3042 abuts against the first plane 30412, the extension part 3011 connected to the abutting part 3042 stops at one end of the extension direction of the first through groove 3023, thus limiting one side of the abutting part 3042 in the sliding direction at the abutting position on the first plane 30412. Figure 98 As shown, when the supporting part 3042 abuts against the second plane 30413, the extension part 3011 stops at the other end of the extension direction of the first through groove 3023. Therefore, the supporting part 3042 can be limited on the other side of the sliding direction of the abutment position on the second plane 30413. This configuration can limit the sliding displacement of the second connector 302, reduce excessive displacement or positional deviation that may occur during the sliding of the second connector 302, and ensure that it moves smoothly and accurately within a predetermined range.

[0357] By providing a first plane 30412 and a second plane 30413 at both ends of the inclined surface 30411, the supporting part 3042 can abut against the first plane 30412 and the second plane 30413 respectively when the cleaning mechanism 303 is in the mopping position and the lifting position. This design utilizes the self-weight of the cleaning mechanism 303 to achieve self-locking between the supporting part 3042 and the lifting surface 3041. This improves the stability of the cleaning mechanism 303 in both working states and prevents accidental movement or positional changes caused by external forces or vibrations.

[0358] In some embodiments, please refer to Figures 161 to 163Along the height direction of the second connector 302, a blocking portion 3026 is provided on the side of the first through groove 3023 opposite to the cleaning mechanism 303, and the blocking portion 3026 is located above the first plane 30412 to block the extension portion 3011. When the cleaning mechanism 303 is in the mopping position (i.e., the holding portion 3042 abuts against the first plane 30412), the ground reaction force will cause the cleaning component 110 to tend to move upward. At this time, the blocking portion 3026 can effectively limit the maximum upward movement of the cleaning component 110 by contacting and cooperating with the extension portion 3011. This limiting mechanism can ensure that the cleaning component 110 maintains a stable contact pressure with the ground, thereby ensuring the consistency of the cleaning effect.

[0359] Please see Figure 166 In another embodiment, the shielding portion 3026 has a second groove 30261 on the side facing the extension portion 3011, and the extension portion 3011 has a protrusion 30112 that matches the second groove 30261 on the side facing the shielding portion 3026. When the cleaning mechanism 303 is in the mopping position, the extension portion 3011 moves upward under the push of the ground reaction force, and the protrusion 30112 will correspondingly engage in the second groove 30261. This design can limit the movement of the extension portion 3011 along the outward expansion and inward contraction direction of the cleaning component 110, thereby improving the horizontal installation stability of the cleaning component 110 relative to the body 200 when in the mopping position. Therefore, the probability of horizontal displacement of the cleaning component 110 during the cleaning operation can be reduced, further improving the cleaning effect of the cleaning component 110. It should be noted that even without the push of ground reaction force, the protrusion and the second groove will slightly engage. Slight engagement means that the protrusion 30112 and the second groove 30261 are not tightly engaged.

[0360] Please see Figure 166 The end of the shielding part 3026 facing the second plane 30413 is provided with a clearance slope. During the process of the supporting part 3042 moving from the first plane 30412 to the second plane 30413, the clearance slope can form a clearance space on the moving path of the extension part 3011 to ensure the smoothness of the extension part 3011 during the movement.

[0361] To improve the sliding accuracy of the second connector 302 relative to the first connector 301 and reduce the probability of lateral offset during sliding, optionally, in one embodiment of this utility model, please refer to... Figure 101 , Figure 105 , Figure 109 and Figure 110A second guide component 305 is provided between the first connector 301 and the second connector 302 to guide the second connector 302 to slide along the first connector 301. The second guide component 305 can be a guide rail and slider structure, with one of the guide rail and slider disposed on the first connector 301 and the other on the second connector 302. Sliding between the slider and the guide rail achieves sliding guidance between the second connector 302 and the first connector 301. Alternatively, the second guide component 305 can be a protrusion and groove structure, with one of the protrusion and the groove disposed on the first connector 301 and the other on the second connector 302. Sliding between the protrusion and the groove achieves sliding guidance between the second connector 302 and the first connector 301.

[0362] By setting the second guide component 305, the second guide component 305 can ensure that the second connector 302 slides relative to the first connector 301 in a predetermined direction, reducing the probability of offset or shaking between them during the sliding process, thereby reducing the jamming phenomenon during the sliding process and improving the smoothness of the sliding of the second connector 302.

[0363] Optionally, in one embodiment of this utility model, please refer to Figure 101 , Figure 105 , Figure 109 and Figure 110 The second guide component 305 includes a sliding cavity 3051 and a second sliding portion 3052. The sliding cavity 3051 is disposed on the first connector 301, and the second sliding portion 3052 is disposed on the second connector 302. The second connector 302 is disposed within the sliding cavity 3051 and is slidably connected to the sliding cavity 3051 via the second sliding portion 3052. The length direction of the sliding cavity 3051 is consistent with the sliding direction of the second connector 302. The two ends of the sliding cavity 3051 in the length direction can be closed or open, as long as the sliding stroke requirement of the second connector 302 relative to the first connector 301 is met. Optionally, in this embodiment, as... Figure 109 As shown, the sliding cavity 3051 is open at both ends in the extending direction, and the second connecting member 302 can move to the outside of the extending direction of the sliding cavity 3051 during the sliding process, such as... Figure 105 As shown. This design helps to reduce the length of the first connector 301 and lower the overall weight of the cleaning assembly 100.

[0364] Please see Figure 105 , Figure 108 and Figure 111The bottom wall of the second connector 302 slidably abuts against the bottom wall of the sliding cavity 3051. The bottom wall of the sliding cavity 3051 is provided with a second through groove 3053 for the extension 3011 to pass through, and the second through groove 3053 at least partially overlaps with the first through groove 3023. Along the height direction of the cleaning mechanism 303, the extension 3011 passes through the second through groove 3053 and the first through groove 3023 sequentially from bottom to top and then connects with the supporting part 3042. Please refer to [link / reference]. Figure 101 , Figure 105 and Figure 109 The second connector 302 has two second sliding portions 3052 formed on its two sidewalls in the width direction, and the two second sliding portions 3052 are respectively connected to the sliding cavity 3051 in the width direction (e.g., Figure 109 The two sidewalls on the Y3 axis slide against each other.

[0365] By providing a sliding cavity 3051 on the first connector 301, not only can the sliding of the second connector 302 be guided, but the sliding cavity 3051 can also increase the overall strength and rigidity of the first connector 301, thereby improving its load-bearing capacity. Furthermore, placing the second connector 302 within the sliding cavity 3051 further reduces the installation space of the cleaning assembly 100 in the height direction, improving the compactness of the structural design.

[0366] Alternatively, in one embodiment, please refer to Figure 90 , Figure 94 and Figure 101The cleaning component mounting cavity 260 includes an upper end wall, which is disposed on the side facing the cleaning mechanism 303. A first connector 301, with its end facing away from the cleaning mechanism 303, is connected to the upper end wall to connect the cleaning component 100 to the body 200. The upper end wall forms an upper shield for the sliding cavity 3051, and a second connector 302 is sandwiched between the first connector 301 and the upper end wall. A support strip 3025 is provided on the surface of the second connector 302 facing away from the cleaning mechanism 303. The support strip 3025 protrudes towards the upper end wall and extends along the moving direction of the second connector 302 relative to the first connector 301. One or more support strips 3025 can be provided. Optionally, in this embodiment, two support strips 3025 are provided, spaced apart along the width direction of the second connector 302. By providing the support strip 3025, firstly, the contact area between the second connector 302 and the cleaning component mounting cavity 260 can be reduced, decreasing the friction generated between the second connector 302 and the cleaning component mounting cavity 260 during movement, thus making the sliding of the second connector 302 smoother. Secondly, the support strip 3025 slides against the upper wall of the cleaning component mounting cavity 260, preventing the second connector 302 from moving upwards or bending and deforming, thereby improving the sliding stability of the second connector 302 between the upper wall and the first connector 301. Thirdly, the support strip 3025 can also increase the structural strength of the second connector 302, reducing the probability of the second connector 302 warping or deforming during use, thereby further improving the smoothness and stability of the sliding of the second connector 302 relative to the first connector 301.

[0367] Alternatively, in another embodiment, the support bar 3025 can be replaced with a bearing support. The bearing support includes a mounting base, a connecting shaft, and a bearing. The mounting base is fixedly connected to the side wall of the second connector 302 opposite to the cleaning mechanism 303. The bearing is sleeved on the connecting shaft, which is fixedly connected to the mounting base. The outer ring of the bearing makes rolling contact with the upper end wall of the cleaning component mounting cavity 260. Multiple bearing supports can be provided, and the bearings of these supports roll along the moving direction of the second connector 302. This arrangement can also reduce the contact friction between the second connector 302 and the cleaning component mounting cavity 260, thereby improving the smoothness of movement of the second connector 302.

[0368] When the second connector 302 slides relative to the first connector 301, it can be done by manually pushing the second connector 302. Alternatively, a driving component can be additionally provided between the first connector 301 and the second connector 302 to drive the second connector 302 to slide relative to the first connector 301. Optionally, in one embodiment of this invention, please refer to... Figure 94 and Figure 97 A drive assembly 306 is provided between the first connecting member 301 and the second connecting member 302. The fixed end of the drive assembly 306 is connected to the first connecting member 301, and the driving end of the drive assembly 306 is connected to the second connecting member 302. When the drive assembly 306 operates, it causes the second connecting member 302 to slide relative to the first connecting member 301. The drive assembly 306 can be any linear drive mechanism capable of enabling the second connecting member 302 to slide relative to the first connecting member 301, such as a motor and rack and pinion structure, a motor and ball screw structure, a cylinder or hydraulic cylinder, or a flexible rope structure.

[0369] By setting the drive component 306, the sliding movement of the second connector 302 relative to the first connector 301 can be automatically controlled, thereby improving operational efficiency and control precision. At the same time, since the drive component 306 can automatically control the sliding movement of the first connector 301, there is no need to reserve space for manual operation on the cleaning component 100, thereby improving the compactness of the internal structure of the cleaning component 100.

[0370] Please see Figure 99 , Figure 110 and Figure 113 Optionally, in one embodiment of the present invention, the drive assembly 306 includes a second drive member 3061, a gear transmission assembly 3062, and a gear and rack transmission assembly 3063. The gear transmission assembly 3062 includes a first gear 30621 and a second gear 30622. The gear and rack transmission assembly 3063 includes a drive shaft 30631, a third gear 30632, and a rack 30633. The second drive member 3061 is mounted on the first connecting member 301. The second drive member 3061 can be any mechanism capable of outputting rotary motion, such as a motor, a combination of a motor and a reducer, or a hydraulic pump. Optionally, in this embodiment, such as... Figure 111 As shown, the second driving component 3061 is a motor. A first gear 30621 is connected to the output shaft of the second driving component 3061. A second gear 30622 is mounted on one end of the transmission shaft 30631 and meshes with the first gear 30621. The transmission shaft 30631 extends along the width direction of the second connecting member 302 and at least partially extends into the sliding cavity 3051. A third gear 30632 is mounted on the transmission shaft 30631 and disposed inside the sliding cavity 3051, and is coaxially arranged with the second gear 30622.

[0371] Please see Figure 113 and Figure 116The rack 30633 is mounted on the side wall of the second connector 302 facing the bottom wall of the sliding cavity 3051, and the longitudinal direction of the rack 30633 is consistent with the longitudinal direction of the second connector 302. Along the height direction of the cleaning assembly 100, the rack 30633 meshes with the lower third gear 30632. The rack 30633 can be integrally formed with the second connector 302, or it can be a separate part, fixedly connected to the second connector 302 by bolts or other fasteners. Optionally, in this embodiment, please refer to... Figure 116 The rack 30633 is integrally formed on the second connector 302. This design eliminates the need for assembling the rack 30633 on the second connector 302, which helps improve the assembly efficiency of the cleaning component 100.

[0372] The second driving component 3061 drives the first gear 30621 to rotate. The first gear 30621, through meshing transmission, drives the second gear 30622 to rotate. The second gear 30622 drives the transmission shaft 30631 to rotate. The rotation of the transmission shaft 30631 drives the third gear 30632 to rotate. The third gear 30632 meshes with the rack 30633, thereby causing the rack 30633 to move horizontally along its own length. Through the horizontal movement of the rack 30633, the second connecting component 302 slides relative to the first connecting component 301.

[0373] It should be noted that, in other embodiments, the rack 30633 may be mounted on the side wall of the second connector 302 opposite to the cleaning mechanism 303, and the third gear 30632 may be disposed above the rack 30633 and mesh with it. This arrangement allows for horizontal movement of the rack during the operation of the second drive member 3061, thereby enabling the second connector 302 to slide relative to the first connector 301.

[0374] The second driving component 3061 provides rotational power, which is transmitted and converted through the gear transmission assembly 3062 and the gear and rack transmission assembly 3063. This transmission method results in a relatively smooth operation, which helps improve the smoothness of the sliding process of the second connecting component 302. At the same time, since the gear and rack transmission has high transmission efficiency and accuracy, it helps to reduce power loss during transmission and improve the control accuracy of the sliding speed and running position of the second connecting component 302.

[0375] Under the condition of meeting the transmission requirements of the drive assembly 306, the gear transmission assembly 3062 in the above embodiment can be a variety of gear structures such as two meshing spur gears, helical gears, and bevel gears. Optionally, in this embodiment, please refer to... Figure 111The gear transmission assembly 3062 includes two bevel gears, namely, the first gear 30621 and the second gear 30622 are both bevel gear structures. For details, please refer to [link to relevant documentation]. Figure 109 and Figure 111 The first connecting member 301 has a receiving cavity 3012 on one side of the sliding cavity 3051 in the width direction, and the receiving cavity 3012 communicates with the sliding cavity 3051. The second driving member 3061 is disposed within the receiving cavity 3012. Please refer to [link / reference]. Figure 94 A protective cover 309 can also be provided at the opening of the accommodating cavity 3012. The protective cover 309 is detachably connected to the first connecting member 301. The protective cover 309 can protect the second driving member 3061 inside the accommodating cavity 3012, thereby reducing the probability of the second driving member 3061 being damaged by bumps during use. Figure 111 As shown, the second driving member 3061 is installed along the length direction of the first connecting member 301 so that the output shaft of the second driving member 3061 is perpendicular to the transmission shaft 30631, thereby realizing the meshing between the first gear 30621 and the second gear 30622.

[0376] By configuring the first gear 30621 and the second gear 30622 as bevel gears, a perpendicular arrangement can be achieved between the output shaft of the second drive member 3061 and the transmission shaft 30631. This structural arrangement makes it easier to place the second drive member 3061 outside the sliding cavity 3051, reducing the probability of interference between the installation position of the second drive member 3061 and the sliding cavity 3051. It also helps to reduce the width of the first connecting member 301, improving the compactness of the structural design.

[0377] To facilitate the installation of the drive shaft 30631 on the first connecting member 301, optionally, in one embodiment of this utility model, please refer to... Figure 109 and Figure 111 The first connecting member 301 has a mounting shaft hole 3013 on one side and a locking interface 3014 on the other side. One end of the drive shaft 30631 is rotatably mounted in the mounting shaft hole 3013, and the other end of the drive shaft 30631 is engaged with the locking interface 3014. Along the width direction of the first connecting member 301, the mounting shaft hole 3013 can be located on the side of the first connecting member 301 away from the second driving member 3061, or it can be located on the side of the first connecting member 301 closer to the second driving member 3061. Optionally, in this embodiment, along the width direction of the first connecting member 301, the mounting shaft hole 3013 is located on the side of the first connecting member 301 away from the second driving member 3061. Specifically, it is located on the wall of the sliding cavity 3051 on the side away from the second driving member 3061. The locking interface 3014 is located on the side of the first connecting member 301 closer to the second driving member 3061, that is, on the wall of the accommodating cavity 3012 on the side away from the sliding cavity 3051.

[0378] The drive shaft 30631 and the mounting shaft hole 3013 can be rotatably connected via a shaft hole fit, or they can be rotatably connected via a bearing. Specifically, in this embodiment, please refer to... Figure 111 An eighth bearing 307 is provided in the mounting shaft hole 3013. The end of the transmission shaft 30631 away from the second driving member 3061 is connected to the eighth bearing 307, thereby realizing the rotational connection between the transmission shaft 30631 and the mounting shaft hole 3013.

[0379] The card interface 3014 can be a U-shaped bayonet, a semi-cylindrical bayonet, or other structures that mate with the shaft diameter of the drive shaft 30631. To facilitate the engagement between the drive shaft 30631 and the card interface 3014 and reduce the opening depth of the card interface 3014, optionally, in this embodiment, such as... Figure 109 and Figure 111 As shown, the card interface 3014 is a semi-cylindrical bayonet structure with the opening facing upwards.

[0380] Please see Figure 154 The protective cover 309 is provided with a snap-fit ​​opening 3091 corresponding to the snap-fit ​​interface 3014. After the protective cover 309 is installed above the receiving cavity 3012, the snap-fit ​​opening 3091 is snapped onto the top of the drive shaft 30631 and cooperates with the snap-fit ​​interface 3091 to restrict the installation position of the drive shaft 30631 in the radial direction at the snap-fit ​​interface 3014, thereby improving the transmission accuracy of the drive shaft 30631.

[0381] Since one end of the drive shaft 30631 is snapped into the slot 3014 and the other end is rotatably connected to the mounting hole 3013, during assembly, one end of the drive shaft 30631 can be snapped into the slot 3014 first. By pushing the drive shaft 30631 axially, the other end of the drive shaft 30631 can be inserted into the mounting hole 3013, thus achieving connection with the mounting hole 3013. With this structure, the gears mounted on the drive shaft 30631 do not need to be removed during installation, allowing the gears to be installed on the drive shaft 30631 in advance, improving the installation efficiency of the drive assembly 306. Simultaneously, the snap-fit ​​structure facilitates the assembly and disassembly of the drive shaft 30631 and the first connecting member 301, thereby simplifying assembly and disassembly.

[0382] To further simplify the assembly process of the drive component 306 and improve assembly efficiency, optionally, in one embodiment of this utility model, please refer to... Figure 111 and Figure 117The second gear 30622 and the third gear 30632 are integral components. The second gear 30622 and the third gear 30632 can be formed as an integral component through casting or welding. By making the second gear 30622 and the third gear 30632 as integral components, the number of parts and assembly steps in the assembly process can be reduced, simplifying the assembly process and thus improving the overall assembly efficiency of the drive assembly 306.

[0383] Optionally, in one embodiment of this utility model, please refer to Figure 100 , Figure 101 and Figure 109 A first positioning detection component 308 is provided between the first connector 301 and the second connector 302. The first positioning detection component 308 is used to detect whether the second connector 302 is in the first sliding position or the second sliding position. Figure 98 As shown, when the second connector 302 is in the first sliding position, the cleaning mechanism 303 is in the raised position, that is, the cleaning component 110 is no longer in contact with the ground. Figure 100 As shown, when the second connector 302 is in the second sliding position, the cleaning mechanism 303 is in the mopping position, that is, the cleaning component 110 is in contact with the ground to perform normal cleaning operations. The first positioning detection component 308 is electrically connected to the second driving component 3061. The first positioning detection component 308 includes a first detection switch 3081 and a first stop 3082. One of the first detection switch 3081 and the first stop 3082 is disposed on the first connector 301, and the other is disposed on the second connector 302. Optionally, in this embodiment, the first stop 3082 is disposed on the second connector 302, and the first detection switch 3081 is disposed on the first connector 301. Since the first connector 301 is a fixed component, this arrangement facilitates the wiring of the first detection switch 3081. The first detection switch 3081 can be any structure that can meet the positioning detection requirements, such as a mechanical positioning detection switch, a photoelectric positioning detection switch, or a Hall sensor detection switch. In this embodiment, the first detection switch 3081 is an optocoupler detection switch. Because optocoupler detection switches have many advantages such as strong anti-interference ability, fast response speed and high reliability, they can achieve better positioning detection accuracy and detection stability.

[0384] The number of first detection switches 3081 and first stops 3082 is unlimited. In this embodiment, please refer to... Figure 100 , Figure 101 , Figure 102 and Figure 109A first detection switch 3081 is provided on the first connecting member 301. Two first stops 3082 are provided on the second connecting member 302, and the two first stops 3082 are spaced apart along the length of the second connecting member 302. For ease of description, the two first stops 3082 are labeled as stop one 30821 and stop two 30822, respectively. Figure 98 As shown, when the first connector 301 slides relative to the second connector 302, when the first connector 301 is at one end of the sliding direction, the stop block 30821 triggers the first detection switch 3081, generating a first positioning electrical signal. The first positioning electrical signal corresponds to the first sliding position of the second connector 302. Figure 100 As shown, when the first connector 301 is at the other end of the sliding direction, the second stop 30822 triggers the first detection switch 3081, generating a second positioning electrical signal. The second positioning electrical signal corresponds to the second sliding position of the second connector 302. The first and second positioning electrical signals are electrically connected to the second drive unit 3061 through the control system on the cleaning device 1000. The second drive unit 3061 can control the first and second sliding positions of the second connector 302 according to the first and second positioning electrical signals, thereby realizing the automatic switching of the cleaning mechanism 303 between the rising position and the mopping position.

[0385] In other embodiments, two first detection switches 3081 and one first stop block 3082 may be provided. The first detection switches 3081 are spaced apart along the length of the first connector 301. When the first connector 301 is located at one end in the sliding direction, the first stop block 3082 triggers one of the first detection switches 3081 to generate a first positioning signal. When the first connector 301 is located at the other end in the sliding direction, the first stop block 3082 triggers the other first detection switch 3081 to generate a second positioning signal.

[0386] By setting the first positioning detection component 308, the first positioning detection component 308 can automatically trigger the generation of a positioning electrical signal, reducing manual intervention and thus improving the timeliness and accuracy of the sliding process control of the first connector 301. At the same time, since the first positioning detection component 308 can accurately detect the position of the second connector 302, it can ensure that it can accurately reach the first sliding position and the second sliding position during the sliding process.

[0387] In the prior art, the cleaning component 110 on the cleaning equipment 1000 is usually fixed in position relative to the body 200. Due to the limitation of the body 200 of the cleaning equipment 1000, the cleaning component 110 has certain area limitations when performing cleaning work. For example, the cleaning component 110 cannot clean the corners of the surface to be cleaned, which affects the cleaning effect.

[0388] To resolve the above issues, please refer to Figures 118 to 120 In some embodiments, this utility model also provides a cleaning component 100, which is provided with a translation mechanism 400. The translation mechanism 400 can drive the cleaning mechanism 303 to move horizontally relative to the body 200, so that the cleaning mechanism 303 has an inward position or an outward position, thereby improving the cleaning effect of the cleaning equipment 1000.

[0389] Please see Figures 118 to 120 The cleaning component 100 includes a first connector 301, a second connector 302, and a cleaning mechanism 303.

[0390] The first connector 301 is detachably connected to the bottom of the body 200. The detachable connection method can be referred to the relevant structural description in the previous embodiment, and will not be repeated here.

[0391] To improve the sliding accuracy of the second connector 302 relative to the first connector 301 and reduce the probability of lateral offset during sliding, optionally, in one embodiment of this utility model, please refer to... Figure 101 , Figure 105 , Figure 109 and Figure 110 A second guide component 305 is provided between the first connector 301 and the second connector 302 to guide the second connector 302 to slide along the first connector 301. The specific structure of the second guide component 305 can be referred to the relevant description in the above embodiments, and will not be described in detail here.

[0392] Please see Figure 96 and Figure 119 The cleaning mechanism 303 is movably mounted on the first connector 301, and the cleaning mechanism 303 has an outwardly extended position relative to the first connector 301 (e.g., Figure 119 (as shown) and the inward position (as shown) Figure 96 (As shown). The specific structure of the cleaning mechanism 303 can be referred to the relevant description of the cleaning mechanism 303 in the above embodiments, and will not be repeated here. Figure 155 As shown, when the cleaning mechanism 303 is in the extended position, at least a portion of the edge of the cleaning component 110 lies outside the widest edge projection area of ​​the body 200. Figure 156 As shown, when the cleaning mechanism 303 is in the retracted position, the edge of the cleaning component 110 is located within the widest edge projection area of ​​the body 200.

[0393] Please see Figures 118 to 120A translation mechanism 400 is provided between the cleaning mechanism 303 and the second connecting member 302. During the sliding process of the second connecting member 302 relative to the first connecting member 301, the translation mechanism 400 drives the cleaning mechanism 303 to move horizontally, so that the cleaning mechanism 303 is in an expanded or retracted position. For ease of description, when the cleaning mechanism 303 is in the retracted position, the sliding position of the second connecting member 302 relative to the first connecting member 301 is defined as the third sliding position (e.g., ...). Figure 96 As shown), when the cleaning mechanism 303 is in the outward expansion position, the sliding position of the second connector 302 relative to the first connector 301 is positioned as the fourth sliding position (as shown). Figure 119 (As shown).

[0394] For example, when the cleaning component 100 needs to clean the corners of the floor, the translation mechanism 400 drives the cleaning mechanism 303 from the retracted position to the expanded position, so that at least a portion of the edge of the cleaning component 110 is outside the widest edge projection area of ​​the body 200, thereby completing the corner cleaning. In another example, when the cleaning component 100 needs to perform normal cleaning operations on the floor (without cleaning the corners), the translation mechanism 400 drives the cleaning mechanism 303 from the expanded position to the retracted position, so that the edge of the cleaning component 110 is within the widest edge projection area of ​​the body 200, thereby completing the normal floor cleaning operation.

[0395] It should be noted that when the translation mechanism 400 drives the cleaning mechanism 303 to move horizontally, the cleaning mechanism 303 can move horizontally along its own length or along its width. Optionally, please refer to... Figure 118 and Figure 119 In this embodiment, the cleaning mechanism 303 moves horizontally along its length to switch between an inward and outward position. This allows the cleaning mechanism 303 to switch between the inward and outward positions with a small amount of horizontal displacement, effectively improving switching efficiency and space utilization at the bottom of the body 200.

[0396] The translation mechanism 400 can be a structure of a chute and a sliding block. The chute is located on the first connecting member 301, and its extension direction is consistent with the horizontal movement direction of the cleaning mechanism 303. One end of the sliding block is connected to the cleaning mechanism 303, and the other end is connected to the second connecting member 302. When the second connecting member 302 slides relative to the first connecting member 301, the sliding block slides within the chute, thereby causing the cleaning mechanism 303 to move horizontally relative to the first connecting member 301. Alternatively, the translation mechanism 400 can be a structure of a guide rail and a slider. The guide rail is mounted on the first connecting member 301, and its length direction is consistent with the horizontal movement direction of the cleaning mechanism 303. Both the cleaning mechanism 303 and the second connecting member 302 are fixed to the slider, which is slidably mounted on the guide rail via a guide rail pair. When the second connecting member 302 slides relative to the first connecting member 301, the slider slides along the guide rail, thereby causing the cleaning mechanism 303 to move horizontally relative to the first connecting member 301.

[0397] The cleaning component 100 of this invention, by incorporating a translation mechanism 400, drives the cleaning mechanism 303 to move horizontally when the second connecting member 302 slides relative to the first connecting member 301, allowing the cleaning mechanism 303 to switch between an expanded position and a retracted position. With this configuration, during normal cleaning operations (when corners are not required), the cleaning component 110 can clean the surface only in the retracted position. This reduces the area of ​​the cleaning component 110 extending beyond the machine body, thereby reducing the probability of accidental damage to the cleaning mechanism 303 due to external collisions or friction. Therefore, it is more suitable for operation in complex environments, such as scenarios requiring frequent movement or cleaning operations in confined spaces. When the cleaning device 1000 needs to clean the corners of the surface, the cleaning component 110 can move from the retracted position to the expanded position, thereby achieving effective cleaning of the corner areas and improving the cleaning effect of the cleaning device 1000 on corners.

[0398] Optionally, in one embodiment of this utility model, the range of the outward and inward retraction stroke of the cleaning mechanism 303 is 40-50mm, that is, the horizontal stroke range of the cleaning mechanism 303 from the inward position to the outward position is 40-50mm. Preferably, the outward and inward retraction stroke of the cleaning mechanism 303 is 46.5mm. Limiting the outward and inward retraction stroke of the cleaning mechanism 303 to the range of 40-50mm ensures that the cleaning component 100 can cover the predetermined corner cleaning area when in the outward position, and also avoids the cleaning component 110 from excessively retracting inward, resulting in insufficient cleaning range, thereby helping to ensure the consistency of cleaning effect. At the same time, since excessive stroke may overload the translation mechanism (such as motor, cylinder, etc.) and shorten its service life, limiting the outward and inward retraction stroke of the cleaning mechanism 303 to the range of 40-50mm can avoid excessive stroke of the translation mechanism 400, thereby protecting the translation mechanism 400 and extending its service life.

[0399] Optionally, in one embodiment of this utility model, please refer to Figure 155 When the cleaning mechanism 303 is in the extended position, along the moving direction of the cleaning mechanism 303, the outer edge of the cleaning mechanism 303 extends beyond the outer edge of the body 200 by a dimension D of 7-9 mm, for example, 7 mm, 8 mm, or 9 mm, preferably D is 8.75 mm. The outer edge of the cleaning component 110 mounted on the cleaning mechanism 303 extends beyond the outer edge of the body 200 by a dimension C of 2-4 mm, for example, 2 mm, 3 mm, or 4 mm, preferably C is 3 mm. By limiting the dimension D of the outer edge of the cleaning mechanism 303 extending beyond the outer edge of the body 200 to between 7 and 9 mm, it is ensured that the extended position of the cleaning mechanism 303 can cover a larger cleaning area, ensuring that the cleaning component 110 can reach farther locations, especially hard-to-clean areas such as walls and corners, while also avoiding excessive load on the translation mechanism 400 due to excessive extension. By limiting the outer edge of the cleaning component 110 to extend beyond the outer edge of the body 200 by a dimension C of 2 to 4 mm, it is ensured that the cleaning component 110 can effectively cover the corner area outside the body 200, reducing the area of ​​blind spots in the cleaning operation, thereby improving the cleaning effect of the corner positions.

[0400] Optionally, in one embodiment of this utility model, please refer to Figure 105 , Figure 109 , Figure 118 and Figure 120The translation mechanism 400 includes a second through groove 3053 and a connecting assembly 320. The second through groove 3053 is disposed on the first connecting member 301, and the cleaning mechanism 303 is connected to the second connecting member 302 via the connecting assembly 320. The connecting assembly 320 is at least partially slidably connected to the second through groove 3053. The second through groove 3053 extends along the length direction of the cleaning mechanism 303, and one, two, or more second through grooves 3053 may be provided. Optionally, in this embodiment, please refer to... Figure 109 and Figure 111 Along the width direction of the first connector 301, two second through slots 3053 are arranged side by side. A portion of the connecting assembly 320 is slidably connected to one of the two second through slots 3053, and the other portion of the connecting assembly 320 is slidably connected to the other second through slot 3053. This improves the smoothness of the translation mechanism 400 driving the second connector 302 to move. One or more connecting assemblies 320 can be provided. Optionally, please refer to... Figure 118 In this embodiment, two connecting components 320 are provided along the length of the cleaning mechanism 303. This creates two lifting points along the length of the cleaning mechanism 303, effectively distributing its weight and preventing tilting or swaying caused by single-point force, thus further improving the stability of the translational movement of the cleaning mechanism 303.

[0401] Under the condition that the connection relationship between the second connector 302 and the cleaning mechanism 303 is satisfied, the specific structure of the connecting component 320 is not limited in this embodiment. For example, the connecting component 320 can be a combination of a connecting block and a fastener. One end of the connecting block is connected to the cleaning mechanism 303, and the other end of the connecting block passes through the second through groove 3053 and is fixedly connected to the bottom surface of the second connector 302 by fasteners (such as bolts, screws, etc.). The connecting component 320 can also be a combination of a connecting block and a snap-fit ​​structure. One end of the connecting block is connected to the cleaning mechanism 303, and the other end of the connecting block is engaged with the snap-fit ​​mechanism provided on the second connector 302 to realize the connection between the second connector 302 and the cleaning mechanism 303.

[0402] In this embodiment, through the cooperation of the second through groove 3053 and the connecting component 320, when the second connecting member 302 slides relative to the first connecting member 301, the connecting component 320 can drive the cleaning mechanism 303 to move horizontally, thereby realizing the switching between the inward and outward positions. This structural design can reduce the complex transmission components in the traditional translation mechanism 400 and simplify the overall mechanical structure. At the same time, due to the smaller number of parts and the simplified structure, it is beneficial to reduce the manufacturing cost of the cleaning equipment 1000.

[0403] Optionally, in one embodiment of this utility model, please refer to Figures 120 to 123The connecting assembly 320 includes a connecting end 3015, a supporting portion 3042, and a snap-fit ​​groove 321. The supporting portion 3042 is located on the side of the second connecting member 302 opposite to the cleaning mechanism 303, and the snap-fit ​​groove 321 is located on the same side of the second connecting member 302 opposite to the cleaning mechanism 303. The supporting portion 3042 snaps into the snap-fit ​​groove 321 and can limit its movement in the sliding direction of the second connecting member 302. (See also...) Figure 120 and Figure 123 One end of the connecting end 3015 is connected to the side of the cleaning mechanism 303 facing the first connector 301. The other end of the connecting end 3015 passes through the bottom wall of the second through groove 3053 and the second connector 302 along the height direction of the cleaning mechanism 303 from bottom to top, and then connects to the supporting part 3042. The snap-fit ​​groove 321 is supported below the supporting part 3042, and the supporting part 3042 is pressed against the bottom wall of the snap-fit ​​groove 321 by the gravity of the cleaning mechanism 303.

[0404] For ease of description, the specific structure of component 320 at either end will be used as an example for detailed explanation. Please refer to [link to documentation]. Figures 120 to 122 At one end of the second connector 302 along its length, the bottom wall of the second connector 302 is provided with two first through slots 3023. Along the width direction of the second connector 302, the two first through slots 3023 are respectively located on both sides of the snap-fit ​​slot 321. The shape of the first through slots 3023 is not limited, as long as the extension 3011 can pass through. Please refer to [link / reference]. Figure 120 and Figure 123 The connecting end 3015 includes two extensions 3011, each corresponding to a first through groove 3023. One end of the extension 3011 is connected to the cleaning mechanism 303, and the other end of the extension 3011 passes through the first through groove 3023 and extends at least partially to the side of the second connector 302 opposite to the cleaning mechanism 303. Both ends of the supporting portion 3042 are connected to the two extensions 3011 respectively, thereby achieving a snap-fit ​​connection between the supporting portion 3042 and the snap-fit ​​groove 321, thus achieving the connection between the second connector 302 and the cleaning mechanism 303. By pressing the supporting portion 3042 against the bottom wall of the snap-fit ​​groove 321, the connecting assembly 320 can form a relatively stable connection with the second connector 302 under the gravity of the cleaning mechanism 303. This connection not only reduces the risk of the cleaning mechanism 303 falling due to mechanical loosening but also improves the operational reliability of the cleaning equipment 1000.

[0405] To reduce the installation space occupied by the connection assembly 320 in the height direction of the cleaning device 1000, optionally, please refer to Figures 120 to 122In one embodiment of this utility model, the second connector 302 includes a recess 3021, which is recessed towards the side opposite to the cleaning mechanism 303, and the bottom wall of the recess 3021 slidably abuts against the bottom wall of the sliding cavity 3051. A snap-fit ​​groove 321 is disposed within the recess 3021. A second through groove 3053 is disposed on the bottom wall of the recess 3021, and the extension 3011 passes through the second through groove 3053 and is at least partially located within the recess 3021.

[0406] The recess 3021 allows at least a portion of the extension 3011 and the supporting portion 3042 to be accommodated inside the second connector 302, thereby reducing the installation space occupied by the connecting assembly 320 in the height direction of the cleaning device 1000, making the structure of the entire cleaning device 1000 more compact and helping to reduce the overall height dimension.

[0407] The forming method of the snap-fit ​​groove 321 within the cavity 3021 is not limited. For example, it can be formed by providing two protrusions on the bottom wall of the cavity 3021, with the snap-fit ​​groove 321 formed between the two protrusions and the bottom wall of the cavity 3021. Alternatively, a snap-fit ​​structure can be separately connected to the bottom wall of the cavity 3021. Optionally, in one embodiment of this utility model, please refer to... Figures 120 to 122 The cavity 3021 has a protruding structure 3022 inside. The protruding structure 3022 connects one side wall of the cavity 3021 along its length to the bottom wall of the cavity 3021. A snap-fit ​​groove 321 is formed between the protruding structure 3022, the bottom wall of the cavity 3021, and the side wall of the cavity 3021. It should be noted that the length direction of the cavity 3021 is consistent with the length direction of the second connector 302. For details, please refer to... Figure 122 Along the length of the cavity 3021, the wall of the cavity 3021 on the side away from the protruding structure 3022 is marked as the first sidewall 30211. The engagement groove 321 formed between the protruding structure 3022, the bottom wall of the cavity 3021, and the sidewall of the cavity 3021 refers to the engagement groove 321 formed between the protruding structure 3022, the bottom wall of the cavity 3021, and the first sidewall 30211. The protruding structure 3022 can be a cuboid protrusion, a wedge-shaped protrusion, a trapezoidal protrusion, or other structures; this embodiment does not limit this.

[0408] Since a protruding structure 3022 is provided inside the cavity 3021, and the protruding structure 3022 connects the side wall and the bottom wall of the cavity 3021, this arrangement can improve the connection support strength of the side wall of the snap-fit ​​groove 321, reduce the probability that the snap-fit ​​groove 321 will deform during long-term operation, causing the supporting part 3042 to shift within the snap-fit ​​groove 321, thereby improving the switching accuracy of the cleaning mechanism 303 between the inward and outward positions.

[0409] Optionally, in one embodiment of this utility model, please refer to... Figures 120 to 122 The protruding structure 3022 includes an inclined surface 30411. Along the depth direction of the cavity 3021, the inclined surface 30411 slopes from the bottom wall of the cavity 3021 toward the opening side of the cavity 3021. One end of the inclined surface 30411 is connected to the bottom wall of the cavity 3021. For ease of description, the bottom wall of the cavity 3021 connected to the inclined surface 30411 is marked as the first plane 30412, meaning one end of the inclined surface 30411 is connected to the first plane 30412. The other end of the inclined surface 30411 extends toward the opening side of the cavity 3021. Along the width direction of the cavity 3021, two first through grooves 3023 are respectively disposed on both sides of the inclined surface 30411, and the first through grooves 3023 are elongated groove structures extending along the length direction of the cavity 3021, with the extension portion 3011 slidably installed within the first through groove 3023. When the cleaning mechanism 303 is in the retracted position, under the sliding action of the second connector 302, the supporting part 3042 can slide along the inclined surface 30411 to drive the cleaning mechanism 303 to move up and down relative to the first connector 301.

[0410] The supporting part 3042 can be any structure capable of sliding along the inclined surface 30411, such as a wedge, an arc-shaped block, or a pin. Optionally, in this embodiment, please refer to... Figure 120 The supporting part 3042 is a pin, and each of the two extensions 3011 is provided with a pin mounting hole 30111. The two ends of the pin are respectively installed in the corresponding pin mounting holes 30111. This effectively reduces the frictional force generated when the supporting part 3042 and the inclined surface 30411 move relative to each other, facilitating the sliding of the supporting part 3042 along the inclined surface 30411. It should be noted that the pin and the pin mounting hole 30111 can be either a rotatable connection or a fixed connection; this embodiment is not limited to either.

[0411] For ease of description, in this embodiment, the sliding direction of the second connecting member 302 when the cleaning mechanism 303 moves from the retracted position to the expanded position is defined as the first direction, such as... Figure 96 As indicated by arrow S1. The sliding direction of the second connector 302 when the cleaning mechanism 303 is moved from the expanded position to the retracted position is defined as the second direction, as shown in the image. Figure 119 The direction of arrow S2 is shown in the middle.

[0412] Please see Figures 118 to 120 During the process of the cleaning mechanism 303 moving from the outward expansion position to the inward retraction position, that is, when the second connecting member 302 slides along the second direction, firstly, as Figure 120 and Figure 126As shown, in the initial state, one end of the extension 3011 stops at the end of the second through groove 3053 away from the drive structure 160, and the holding part 3042 engages with the snap-fit ​​groove 321. When the second connector 302 slides along the second direction, it drives the cleaning mechanism 303 to move horizontally synchronously until the cleaning mechanism 303 moves from... Figure 118 The outward expansion position shown has been moved to Figure 124 The inward position is shown. In Figure 124 At the recessed position shown, one end of the second through groove 3053 stops along the second direction on one side of the extension 3011, as shown. Figure 127 As shown, this restricts further horizontal movement of the cleaning mechanism 303 along the second direction. In this state, the cleaning mechanism 303 is in contact with the surface to be cleaned and is in the mopping position.

[0413] Please see Figure 96 and Figure 124 After the cleaning mechanism 303 retracts into place, the second connector 302 continues to slide along the second direction. Under the action of the second through groove 3053, the extension 3011 no longer moves relative to the first connector 301. Please refer to [link / reference]. Figure 120 At this point, the pin begins to slide upward along the inclined surface 30411, and the extension 3011 slides relative to the second connector 302 within the first through groove 3023, thereby driving the cleaning mechanism 303 to move upward relative to the first connector 301, causing the pin to move from... Figure 120 Move to the position shown Figure 98 The position shown enables the cleaning mechanism 303 to be positioned such that... Figure 96 The mopping position shown has been switched to Figure 95 The indicated rising position. Please refer to [link / reference]. Figure 98 When the other end of the first through groove 3023 stops at the other side of the extension 3011 along the second direction, it indicates that the cleaning mechanism 303 has risen to its position. At this time, the second connecting member 302 stops sliding, and the cleaning mechanism 303 stops rising and falling. At this point, the cleaning mechanism 303 is in... Figure 95 The inward-rising position is shown.

[0414] When the cleaning mechanism 303 needs to perform cleaning again, that is, when it needs to switch from the rising position to the mopping position, at this time, along... Figure 95 The second connector 302, which slides in the first direction, has no stop function between the first through groove 3023 and the extension 3011 in the first direction, as shown. Figure 98As shown, therefore, when the second connector 302 slides, it will not cause the extension 3011 to move horizontally in the first direction. At this time, under the action of gravity of the cleaning mechanism 303, the pin begins to slide downward along the inclined plane 30411, and the extension 3011 slides in the opposite direction relative to the second connector 302 in the first through groove 3023, thereby causing the cleaning mechanism 303 to move downward relative to the first connector 301, realizing the lowering action of the cleaning mechanism 303, as shown. Figure 100 As shown. At this time, the pin engages with the locking groove 321 again, that is, the pin contacts the first plane 30412, the cleaning mechanism 303 switches to the mopping position again, the second connecting piece 302 stops sliding, and the cleaning mechanism 303 stops descending. The cleaning mechanism is in... Figure 96 The inward-curving mopping position is shown.

[0415] When the cleaning mechanism needs to expand outwards for corner work, the cleaning mechanism 303 needs to move from the inward position to the outward position, that is, the second connecting member 302 needs to move along the first direction from... Figure 96 Slide the position to Figure 119 The location shown. First, as indicated. Figure 118 and Figure 127 As shown, in the initial state, one end of the extension 3011 stops at the end of the second through groove 3053 away from the drive structure 160, and the holding part 3042 engages with the snap-fit ​​groove 321. When the second connector 302 slides along the first direction, it drives the cleaning mechanism 303 to move horizontally synchronously until the cleaning mechanism 303 moves from... Figure 96 and Figure 99 The inward position shown has been moved to Figure 119 and Figure 124 The indicated outward expansion position. In Figure 124 At the outward expansion position shown, one end of the second through groove 3053 stops along the second direction on one side of the extension 3011, as shown. Figure 126 As shown, this restricts further horizontal movement of the cleaning mechanism 303 along the first direction. In this state, the cleaning mechanism 303 is in the outward mopping position.

[0416] By setting an inclined surface 30411, and with the cleaning mechanism 303 in the retracted position, the pin can slide along the inclined surface 30411 to drive the cleaning mechanism 303 to move up and down relative to the first connecting member 301. This configuration, through the sliding of the second connecting member 302, not only allows switching between the outward and inward positions of the cleaning mechanism 303, but also enables the up and down movement of the cleaning mechanism 303 relative to the first connecting member 301, allowing switching between the mopping position and the raised position. This better meets the cleaning needs of various application scenarios. For example, during cleaning, when the machine body 200 passes over a carpet, the cleaning mechanism 303 can be switched to the raised position to avoid wetting the carpet; or, in scenarios requiring obstacle crossing or returning to the base station, the cleaning mechanism 303 can also be switched to the raised position to prevent it from being stuck by obstacles and detaching from the machine body 200.

[0417] Optionally, in one embodiment of this utility model, please refer to Figures 120 to 122 The protruding structure 3022 also includes a second plane 30413, which is disposed on the side of the inclined plane 30411 away from the first plane 30412. Figure 122 As shown, along the length of the cavity 3021, one end of the second plane 30413 is connected to the side of the inclined plane 30411 away from the first plane 30412, and the other end of the second plane 30413 is connected to the side wall of the cavity 3021 away from the first side wall 30211, and the second plane 30413 and the first plane 30412 are arranged parallel to each other. Figure 98 As shown, when the cleaning mechanism 303 is in the raised position, the supporting part 3042 abuts against the second plane 30413. With this configuration, when the cleaning mechanism 303 is in the raised position, no additional braking force is required; the supporting part 3042 can achieve self-locking between itself and the second plane 30413 solely through the weight of the cleaning mechanism 303 itself. Therefore, this not only simplifies the overall structural design but also ensures the stability of the cleaning mechanism 303 in the raised position, preventing accidental movement or positional changes due to external forces or vibrations.

[0418] When the second connector 302 slides relative to the first connector 301, it can be done by manually pushing the second connector 302. Alternatively, a driving component 306 can be additionally provided between the first connector 301 and the second connector 302, driving the second connector 302 to slide relative to the first connector 301. Optionally, in one embodiment of this invention, please refer to... Figure 97 and Figure 99A drive assembly 306 is provided between the first connecting member 301 and the second connecting member 302. The fixed end of the drive assembly 306 is connected to the first connecting member 301, and the driving end of the drive assembly 306 is connected to the second connecting member 302. The drive assembly 306 drives the second connecting member 302 to slide relative to the first connecting member 301. The drive assembly 306 can be any linear drive mechanism capable of enabling the second connecting member 302 to slide relative to the first connecting member 301, such as a gear and rack structure, a motor and ball screw structure, a cylinder, or a hydraulic cylinder.

[0419] By setting the drive component 306, the sliding movement of the second connector 302 relative to the first connector 301 can be automatically controlled, thereby improving operational efficiency and control precision. At the same time, since the drive component 306 can automatically control the sliding movement of the first connector 301, there is no need to reserve space for manual operation on the cleaning component 100, thereby improving the compactness of the internal structure of the cleaning component 100.

[0420] It should be noted that the driving component 306 in this embodiment can adopt the structure of the driving component 306 in the above embodiments, and thus also have the beneficial effects of the driving component 306 in the above embodiments. Of course, it is understood that in this embodiment, other driving components can also be used to drive the sliding of the second connector 302, as long as the sliding performance requirements of the second connector 302 are met.

[0421] Optionally, in one embodiment of this utility model, please refer to Figure 98 and Figure 100 A first positioning detection component 308 is disposed between the first connector 301 and the second connector 302. The first positioning detection component 308 is used to detect whether the second connector 302 is located in the first sliding position or the second sliding position. The first positioning detection component 308 is electrically connected to the second driving component 3061. The specific structure and setting position of the first positioning detection component 308 can be referred to the relevant structural description in the above embodiments, and will not be repeated here.

[0422] Based on the provision of a first positioning detection component 308 between the first connector 301 and the second connector 302, optionally, in one embodiment of this utility model, please refer to 124 and Figure 125 A second positioning detection component 310 is further provided between the first connector 301 and the second connector 302. The second positioning detection component 310 is used to detect whether the second connector 302 is located in the third sliding position or the fourth sliding position. Figure 128 and Figure 129 As shown, when the second connector 302 is in the third sliding position, the cleaning mechanism 303 is in the retracted position. Figure 130 and Figure 131As shown, when the second connector 302 is in the fourth sliding position, the cleaning mechanism 303 is in the extended position. The second positioning detection component 310 is electrically connected to the second drive component 3061. Figure 125 As shown, the second positioning detection component 310 includes a second detection switch 311 and a second stop 312. One of the second detection switch 311 and the second stop 312 is disposed on the first connector 301, and the other is disposed on the second connector 302. Optionally, in this embodiment, the second stop 312 is disposed on the second connector 302, and the second detection switch 311 is disposed on the first connector 301. Since the first connector 301 is a fixed component, this arrangement facilitates the wiring of the second detection switch 311. The second detection switch 311 can be any structure that meets the positioning detection requirements, such as a mechanical positioning detection switch, a photoelectric positioning detection switch, or a Hall sensor detection switch. In this embodiment, the second detection switch 311 is an optocoupler detection switch. Since optocoupler detection switches have many advantages such as strong anti-interference ability, fast response speed, and high reliability, better positioning detection accuracy and detection stability can be obtained.

[0423] The number of second detection switches 311 and second stops 312 is unlimited. In this embodiment, please refer to... Figure 125 A second detection switch 311 is provided on the first connecting member 301. Two second stops 312 are provided on the second connecting member 302, and the two second stops 312 are spaced apart along the length of the second connecting member 302. For ease of description, the two second stops 312 are respectively labeled as stop three 3121 and stop four 3122. Figure 129 As shown, when the second connector 302 slides relative to the first connector 301, when the second connector 302 is at one end of the sliding direction, the stop block 3121 triggers the second detection switch 311 to generate a third position signal, which corresponds to the third sliding position of the second connector 302. When the second connector 302 is at the other end of the sliding direction, the stop block 4 3122 triggers the second detection switch 311 to generate a fourth position signal, which corresponds to the fourth sliding position of the second connector 302. The third and fourth position signals are electrically connected to the second drive unit 3061 through the controller on the cleaning device 1000. The second drive unit 3061 can control the third and fourth sliding positions of the second connector 302 according to the third and fourth position signals, thereby realizing the automatic switching of the cleaning mechanism between the inward and outward positions.

[0424] In other embodiments, two second detection switches 311 and one second stop block 312 may be provided. The second detection switches 311 are spaced apart along the length of the first connector 301. When the first connector 301 is located at one end in the sliding direction, the second stop block 312 triggers one of the second detection switches 311 to generate a third positioning signal. When the first connector 301 is located at the other end in the sliding direction, the second stop block 312 triggers the other second detection switch 311 to generate a fourth positioning signal.

[0425] By setting a second positioning detection component 310, the second positioning detection component 310 can automatically trigger the generation of a positioning electrical signal, reducing manual intervention and thus improving the timeliness and accuracy of the sliding process control of the second connector 302. At the same time, since the second positioning detection component 310 can accurately detect whether the second connector 302 is in the third or fourth sliding position, it can ensure the repeatability of the positioning accuracy of the cleaning mechanism 303 when switching between the inward and outward positions.

[0426] It should be noted that you should refer to [link / reference]. Figure 132 When the cleaning mechanism 303 is in the retracted, raised position, the stop block 30821 triggers the first detection switch 3081, generating a first positioning electrical signal, while the second detection switch remains in the inactive state. Please refer to [link / reference]. Figure 129 When the cleaning mechanism 303 is in the retracted mopping position, stop block 30822 triggers the first detection switch 3081, generating a second positioning signal. Simultaneously, stop block 3121 triggers the second detection switch 311, generating a third positioning signal. Please refer to [link / reference]. Figure 131 When the cleaning mechanism 303 is in the outward expansion position, the first detection switch remains in the non-triggered state, and the fourth stop 3122 triggers the second detection switch 311 to generate the fourth position electrical signal.

[0427] Please see Figure 133 and Figure 134 In one embodiment of this utility model, the cleaning device 1000 is further provided with a clean water tank 500 and a wastewater tank 600 on its body 200. The clean water tank 500 is used to replenish clean water to the cleaning component 110 so that the cleaning component 110 can remain moist during cleaning operations, achieving wet mopping of the surface to be cleaned and improving the cleaning effect. The wastewater tank 600 is used to store wastewater, and the wastewater generated by the cleaning component 110 after mopping is pumped into the wastewater tank 600.

[0428] Please see Figure 135 and Figure 136The cleaning component 100 has a clean water outlet 501, a sludge suction port 502, and a sludge collection chamber 503 on its housing 180. The sludge suction port 502 is connected to the sludge collection chamber 503. Sludge in the sludge collection chamber 503 is discharged through the sludge suction port 502. Multiple clean water outlets 501 are provided, spaced apart along the length of the housing 180. This arrangement improves the uniformity of water replenishment in the cleaning component 110.

[0429] Please see Figure 135 and Figure 137 The outer surface of the housing 180 is also provided with a clean water delivery pipe 504 and a sludge suction outlet 5021, which is connected to the sludge suction outlet 502. The clean water delivery pipe 504 connects the clean water tank 500 and the clean water outlet 501. The clean water tank 500 delivers clean water to the clean water outlet 501 through the clean water delivery pipe 504. The clean water is sprayed onto the surface of the cleaning component 110 through the clean water outlet 501, thereby immersing the cleaning component 110 in clean water.

[0430] Optionally, please refer to Figure 137 In one embodiment of this utility model, the clean water conveying pipe 504 is at least partially a heat-conducting pipe section 5041, the first driving component 161 is a motor, and the heat-conducting pipe section 5041 is coiled around the first driving component 161 and can conduct heat with the first driving component 161. With this configuration, the heat generated during the operation of the first driving component 161 can be conducted to the heat-conducting pipe section 5041 to heat the clean water in the clean water conveying pipe 504, thereby increasing the temperature of the clean water added to the cleaning component 110 and improving the cleaning effect of the cleaning component 110. Simultaneously, the heat generated during the operation of the first driving component 161 can also be carried away by the continuous flow of clean water in the clean water conveying pipe 504, thus cooling the first driving component 161.

[0431] Alternatively, in one embodiment, please refer to Figure 137 The clean water delivery pipe 504 also includes a transition pipe section 5042. A clean water inlet 505 is also provided on the side of the housing 180 opposite to the cleaning component 110. The clean water inlet 505 is located near the first driving component 161 and communicates with the clean water outlet 501 inside the receiving cavity 190. One end of the transition pipe section 5042 communicates with the outlet of the heat-conducting pipe section 5041, and the other end communicates with the clean water inlet 505. By providing the transition pipe section 5042, the connection between the clean water delivery pipe 504 and the clean water inlet 505 can be facilitated. Simultaneously, since the clean water inlet 505 is located near the first driving component 161, the probability of interference between the second connecting component 302 and the clean water delivery pipe 504 when the second connecting component 302 moves relative to the first connecting component 301 can be reduced, thereby improving the stability and reliability of the cleaning component 100 operation.

[0432] Please see Figure 135 and Figure 136 During the rotation of the cleaning component 110, it first passes through the clean water outlet 501 for clean water replenishment, and then passes through the wastewater collection chamber 503 for wastewater collection. Specifically, in this embodiment, the cleaning component 100 further includes a scraping structure 710, which includes a first scraper 701 and a second scraper 702. The first scraper 701 and the second scraper 702 are spaced apart in the rotation direction of the cleaning component 110 and both extend along the length direction of the cleaning component 110. The first scraper 701, the second scraper 702, and the inner wall of the housing 180 form the aforementioned wastewater collection chamber 503. During the cleaning operation, the cleaning component 110 first passes through the first scraper 701, then through the second scraper 702, and the wastewater on the cleaning component 110 is scraped into the wastewater collection chamber 503 by the squeezing action of the first scraper 701 and the second scraper 702. Please refer to [link to relevant documentation]. Figure 134 , Figure 135 and Figure 137 The sewage outlet 5021 is connected to the sewage tank 600 through a pipe. The sewage in the sewage collection chamber 503 is pumped into the sewage tank 600 through the sewage outlet 502, thereby realizing the collection of sewage on the cleaning component 110.

[0433] It should be noted that after the first squeegee 701 and the second squeegee 702 scrape away the water, the surface of the cleaning component 110 becomes flat under pressure, which affects the cleaning effect of the cleaning component 110. Therefore, please refer to [link / reference needed]. Figure 135 Along the travel direction of the cleaning equipment 1000, the fluffing roller 170 is located at the rear end of the squeegee structure 710, that is, at the rear end of the wastewater collection chamber 503. It can be understood that when the squeegee structure 710 has scraped away the wastewater from the cleaning component 110 and left it flat, the fluffing roller 170 acts on the cleaning component 110 and lifts the nap on its surface, causing the cleaning component 110 to fluff up again. This process reduces the decrease in cleaning effect caused by the squeegee structure 710 flattening the cleaning component 110.

[0434] To further improve the wiping effect of the wiping structure 710, optionally, in one embodiment of this utility model, please refer to... Figure 135 and Figure 136The first wiper 701 includes a plurality of spaced-apart first comb teeth 7011. One end of each first comb tooth 7011 is connected to the inner wall of the housing 180, and the other end extends toward the cleaning component 110. The second wiper 702 is a scraper strip structure, with one end connected to the inner wall of the housing 180 and the other end extending toward one side of the cleaning component 110. This arrangement serves two purposes: firstly, the multiple first comb teeth 7011 can prevent large particles from the cleaning component 110 from entering the wastewater collection chamber 503, significantly reducing the probability of large particles clogging the suction port 502. Secondly, it reduces the contact area between the first wiper 701 and the cleaning component 110, which helps reduce friction and wear during rotation of the cleaning component 110, extending its service life. Simultaneously, because the second wiper 702 uses a scraper strip structure, it can form a relatively tight compression contact surface with the cleaning component 110, thus helping to prevent wastewater from flowing out of the wastewater collection chamber 503 and contaminating the surface to be cleaned.

[0435] Alternatively, in another embodiment, please refer to Figure 135 and Figure 136 The inner wall of the housing 180 is also provided with a comb tooth 720, which is in interference contact with the cleaning component 110. Along the travel direction of the cleaning device 1000, the comb tooth 720 is located at the front end of the first squeegee 701. When the cleaning component 110 performs cleaning operations, it passes sequentially through the comb tooth 720, the first squeegee 701, and the second squeegee 702. The comb tooth 720 extends along the length of the cleaning component 110 and includes multiple second comb teeth 721. A gap is formed between adjacent second comb teeth 721, allowing the comb tooth 720 to prevent large particles from entering the interior of the housing 180, thereby reducing damage to the receiving cavity caused by large particles.

[0436] Please see Figure 133 and Figure 134 The clean water tank 500 is located at the rear edge of the housing 200, which facilitates the base station's replenishment of the clean water tank 500. Similarly, the wastewater tank 600 is typically located at the rear edge of the housing 200 for easy wastewater removal. To save installation space on the housing 200 for the wastewater tank 600 and the clean water tank 500, optionally, in this embodiment, please refer to... Figure 138 and Figure 139The clean water tank 500 includes a mounting cavity 506, the opening of which faces outwards from the body 200. The shape and size of the mounting cavity 506 match the shape and size of the wastewater tank 600, which is fitted into the mounting cavity 506. This not only allows for the integrated installation of the wastewater tank 600 and the clean water tank 500, facilitating their assembly and disassembly on the body 200, but also reduces the horizontal installation area occupied by the clean water tank 500 and the wastewater tank 600 on the body 200, thereby optimizing the spatial layout of the body 200 and improving the compactness of the equipment.

[0437] To improve the installation stability of the clean water tank 500 on the unit body 200, optionally, please refer to Figure 133 and Figure 134 In one embodiment, a water tank mounting cavity 270 is provided at the rear edge of the body 200, and a clean water tank 500 is accommodated within the water tank mounting cavity 270. The side walls of the clean water tank 500 are fixedly connected to the walls of the water tank mounting cavity 270 by bolts. Please refer to [link / reference]. Figure 134 and Figure 138 The bottom of the clean water tank 500 is also equipped with a support plate 507. One end of the support plate 507 is fixedly connected to the body 200, and the other end of the support plate 507 supports the bottom of the clean water tank 500 and is fixedly connected to the bottom wall of the clean water tank 500. This arrangement forms connection support points on both the side wall and the bottom wall of the clean water tank 500, thereby improving the connection strength between the clean water tank 500 and the body 200. At the same time, since the wastewater tank 600 is installed in the mounting cavity 506, the support plate 507 can also specifically enhance the support strength at the installation position of the wastewater tank 600, further improving the installation stability of the wastewater tank 600 and the clean water tank 500 on the body 200.

[0438] Optionally, in one embodiment, the clean water tank 500 is equipped with a first water level detection component (not shown in the figure), and the wastewater tank 600 is equipped with a second water level detection component (not shown in the figure). The first water level detection component can detect the water level in the clean water tank 500 in real time, so as to replenish water in the clean water tank 500 in a timely manner and ensure the degree of wetting of the cleaning component 110. The second water level detection component can detect the water level in the wastewater tank 600 in real time, so as to discharge the wastewater in the wastewater tank 600 in a timely manner and prevent wastewater from overflowing and polluting the ground. The structures of the first water level detection component and the second water level detection component can be the same or different. Optionally, in this embodiment, the structures of the first water level detection component and the second water level detection component are the same.

[0439] The following embodiments use the first water level detection component as an example to introduce its structure.

[0440] The first water level detection component includes a float, a magnet, and a Hall sensor. The float is suspended in the clean water tank 500 and floats up and down with the water level. The magnet is fixed inside the float and moves synchronously with the float's movement. The Hall sensor is fixed to the top or side wall of the clean water tank 500 and detects changes in the magnet's magnetic field. When the magnet moves near the Hall sensor with the float, the Hall sensor senses the change in the magnetic field and outputs a corresponding electrical signal. When the water level in the clean water tank 500 rises, the float rises with the water level, causing the magnet to move upwards. When the magnet approaches the Hall sensor, the Hall sensor detects an increase in magnetic field strength and outputs a high-level signal. When the water level drops, the float sinks with the water level, causing the magnet to move downwards. When the magnet moves away from the Hall sensor, the Hall sensor detects a decrease in magnetic field strength and outputs a low-level signal. By observing the high and low level changes in the Hall sensor's output signal, the water level in the clean water tank 500 can be determined, thus achieving real-time monitoring and control of the water level.

[0441] Of course, in other embodiments, the first water level detection component and the second water level detection component can also be any component capable of liquid level detection, such as an ultrasonic water level detection component or a capacitive water level detection component.

[0442] Please see Figure 137 , Figure 143 and Figure 145 The clean water tank 500 includes a clean water tank inlet 511 and a clean water tank outlet 512, with the outlet 512 connected to the inlet of the clean water delivery pipe 504. A water pump (not shown in the figure) is installed on the clean water delivery pipe 504, and the water pump is mounted on the body 200. The water pump connects the inlet of the heat transfer pipe section 5041 and the clean water tank outlet 512. Through the operation of the water pump, clean water in the clean water tank 500 can be drawn and delivered to the clean water outlet 501, thereby replenishing the cleaning water for the cleaning component 110 and ensuring the consistency and continuity of the cleaning effect.

[0443] Please see Figure 137 , Figure 142 and Figure 143The wastewater tank 600 includes a wastewater tank inlet 601 and a wastewater tank outlet 602. The wastewater tank outlet 602 is located at the bottom of the wastewater tank 600, and the wastewater tank inlet 601 is connected to the wastewater outlet 5021 via a suction pipe. The wastewater tank 600 also includes a negative pressure outlet 603, and a negative pressure pump (not shown in the figure) is installed on the machine body 200, connected to the negative pressure outlet 603. When the negative pressure pump operates, it creates a negative pressure inside the wastewater tank 600. Under the action of negative pressure, wastewater flows out from the wastewater collection chamber 503, passes sequentially through the suction port 502, the suction port outlet 5021, and the suction pipe, and finally enters the wastewater tank 600. This wastewater discharge method enables efficient wastewater collection, thereby improving the continuity of the cleaning process and the consistency of the cleaning effect.

[0444] Alternatively, in one embodiment, please refer to Figure 139 and Figure 149 The clean water tank 500 includes a first clean water tank 520, a second clean water tank 530, and a third clean water tank 540, whose internal cavities are interconnected. The second clean water tank 530 and the third clean water tank 540 are respectively located on opposite sides of the wastewater tank 600, and all three are mounted on a support plate 507, which supports the bottom of the tanks. The first clean water tank 520 is located above the mounting cavity, i.e., above the wastewater tank 600, and its two ends are connected to the second clean water tank 530 and the third clean water tank 540, respectively.

[0445] Please see Figure 142 and Figure 146 The bottom of the third clean water tank 540 is provided with a first balancing port 541, and the bottom of the second clean water tank 530 is provided with a second balancing port 531. A balancing pipe 550 connects the first balancing port 541 and the second balancing port 531. The third clean water tank 540 connects to the second clean water tank 530 via the first balancing port 541, the balancing pipe 550, and the second balancing port 531. This configuration enables real-time balance of water levels in the third clean water tank 540 and the second clean water tank 530, thereby ensuring the stability of the overall center of gravity of the clean water tank 500 and preventing equipment tilting or unstable operation due to uneven water levels.

[0446] Optionally, please refer to Figure 141 and Figure 145In one embodiment, the wastewater tank 600 is provided with a first clean water inlet 604 and a second clean water inlet 605. The first clean water inlet 604 is located on the side wall of the wastewater tank 600 facing the outside of the machine body 200, and the second clean water inlet 605 is located on the side wall of the wastewater tank 600 facing the inside of the machine body 200. The first clean water inlet 604 and the second clean water inlet 605 are connected by a clean water supply pipe 560, which is located inside the wastewater tank 600. The first clean water inlet 604, the second clean water inlet 605, and the clean water supply pipe 560 together form the clean water tank inlet 511.

[0447] Please see Figure 141 and Figure 149 The clean water tank 500 includes a first tank body 570 and a second tank body 580. The first tank body 570 is connected to a support plate 507, and a mounting cavity 506 is disposed in the first tank body 570. A second clean water tank 530 and a third clean water tank 540 are formed in the first tank body 570. The second tank body 580 covers the top of the first tank body 570 and mates with the first tank body 580 to form the first clean water tank 520. Please refer to [link / reference]. Figure 143 and Figure 148 A water supply pipe 508 is integrally formed on the side wall of the clean water tank 500 away from the sewage tank 600, and the water supply pipe 508 extends along the height direction of the clean water tank 500. The lower end of the water supply pipe 508 is connected to the second clean water supply port 605, and the upper end of the water supply pipe 508 is connected to the first clean water tank 520.

[0448] Specifically, please refer to Figure 148 The water supply pipe 508 includes a lower water supply pipe 5081 and an upper water supply pipe 5082. The lower water supply pipe 5081 is formed in the first housing 570, and the upper water supply pipe 5082 is formed in the second housing 580. After the first housing 570 and the second housing 580 are connected and installed, the lower water supply pipe 5081 and the upper water supply pipe 5082 are connected vertically to form a sealed connection. The lower end of the lower water supply pipe 5081 is connected to the second clean water inlet 605, and the upper end of the upper water supply pipe 5082 is connected to the first clean water tank 520, thereby realizing the connection between the second clean water inlet 605 and the clean water tank 500.

[0449] When the clean water in the clean water tank 500 is depleted and needs to be replenished, the cleaning equipment 1000 moves to the base station, aligning the first clean water inlet 604 on the clean water tank 500 with the water outlet on the base station or the water supply outlet of the municipal pipeline. The base station is equipped with a water pump. Under the suction of the water pump, clean water flows sequentially through the first clean water inlet 604, the clean water replenishment pipe 560, the second clean water inlet 605, the lower replenishment pipe 5081, and the upper replenishment pipe 5082, finally entering the clean water tank 500 to complete the water replenishment operation. By setting up the lower replenishment pipe 5081 and the upper replenishment pipe 5082 to replenish the clean water tank 500, compared with the structure using external pipes for water replenishment, this structure does not require the installation of additional replenishment pipes, thus simplifying the assembly process and improving installation efficiency. Meanwhile, since the lower water supply pipe 5081 is integrally formed in the first housing 570 and the upper water supply pipe 5082 is integrally formed in the second housing 580, there is no need to occupy additional installation space outside the clean water tank 500, which is conducive to optimizing the spatial layout on the body 200 and improving the overall compactness of the cleaning equipment 1000.

[0450] Optionally, in one embodiment of this utility model, please refer to Figure 137 The housing 180 is also provided with a dirt detection unit 800 for detecting the degree of dirt on the cleaning component 110 within the receiving cavity 190. The number of dirt detection units 800 is not limited; in this embodiment, one dirt detection unit 800 is provided. In other embodiments, multiple dirt detection units 800 may be provided, spaced apart along the length of the receiving cavity. This allows for multi-area detection of the cleaning component 110, thereby achieving higher dirt detection accuracy.

[0451] Please see Figures 150 to 153 The dirt detection unit 800 includes a color sensor 801 and a supplementary lighting element 802. The housing 180 includes a viewing window 1807 located between the clean water outlet 501 and the wastewater collection chamber 503. The color sensor 801 is mounted on the housing 180 and positioned above the viewing window 1807 to collect the color of the cleaning component 110 through the viewing window 1807, and to determine the degree of dirtiness of the cleaning component 110 based on its color. A certain height space exists between the color sensor 801 and the cleaning component 110 to allow the color sensor 801 to obtain a certain field of view, meeting the detection area requirements. The viewing window 1807 may also be covered with a transparent element, such as glass or quartz, to prevent wastewater from the cleaning component 110 from splashing onto the color sensor 801 and affecting the dirt detection accuracy. The supplementary lighting element 802 includes, but is not limited to, an LED light. The supplementary lighting element 802 is disposed above the transparent element and is used to illuminate the viewing window area 1807 to improve the detection accuracy of the color sensor 801.

[0452] Before the cleaning unit 110 begins operation, the color sensor 801 acquires a surface image of the cleaning unit 110 as a reference image. After the cleaning unit 110 has been operating for a period of time, the color sensor 801 acquires another surface image of the cleaning unit 110 and compares it with the reference image. By analyzing the comparison results, the degree of dirt on the surface of the cleaning unit 110 is determined. When the degree of dirt on the surface of the cleaning unit 110 exceeds a preset threshold, the control system controls the cleaning device 1000 to return to the base station to clean the cleaning unit 110. By setting up the dirt detection unit 800, the dirt status of the cleaning unit 110 can be monitored in real time, ensuring the consistency of the cleaning effect. At the same time, by monitoring the degree of dirt on the cleaning unit 110, unnecessary cleaning operations can be avoided, thereby saving water resources.

[0453] Of course, in the embodiments of this application, the detection of dirt on the cleaning component 110 is not limited to the color sensor 801.
