[0032] In this disclosure, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Rather, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0033] In the embodiments of this disclosure, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0034] In the description of embodiments of this disclosure, the term "at least one" refers to one or more, and "more than one" refers to two or more. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of a single item or a plurality of items. For example, at least one of a, b, or c can represent: a, b, c, a, b, a, c, b, c, or a, b, c, where a, b, and c can be single or multiple.

[0035] In the description of embodiments of this disclosure, the term "and / or" refers to and covers any and all possible combinations of one or more of the associated listed items. The term "and / or" describes an association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " in this disclosure generally indicates that the preceding and following related objects have an "or" relationship.

[0036] In the description of the embodiments disclosed herein, unless otherwise expressly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, "linking" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0037] As used herein, "perpendicular" and "equal" include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "perpendicular" includes absolute perpendicularity and approximate perpendicularity, where the acceptable range of deviation for approximate perpendicularity could be, for example, a deviation within 10°. "Equal" includes absolute equality and approximate equality, where the acceptable range of deviation for approximate equality could be, for example, a difference between the two equalities less than or equal to 10% of either one.

[0038] Under the current technological system, when users operate cleaning equipment (such as floor scrubbers), they usually push the floor scrubber forward first, and then pull it backward. During the forward pushing process, the squeegee at the front of the floor scrubber is in a raised state, maintaining a certain distance from the ground; when the floor scrubber is pulled backward, the squeegee falls and contacts the ground, beginning to scrape away the accumulated water. During the backward pulling process, a certain amount of water scraped up will accumulate at the squeegee.

[0039] If the user pushes the scrubber forward again along the original path, the roller brush will cover the path the squeegee had taken, and the water splashed up will be absorbed and treated by the roller brush. However, if the user deviates from the path when pushing the scrubber forward again—that is, if the user attempts to turn the scrubber to a nearby uncleaned area—the movement trajectory of the roller brush will be inconsistent with the original path of the squeegee when pulling backward previously. Some of the water splashed up by the squeegee during the previous backward pull will be exposed (for example, when the scrubber turns right, some water stains will appear on its left side), thus forming a corner water stain. Furthermore, if the turning operation is performed on the first backward pull of the scrubber, a certain degree of corner water stains will also be generated.

[0040] According to the embodiments of the present disclosure, the floor brush assembly and the cleaning device having therein have a scraper movably disposed on the floor brush body in the vertical direction to switch between a first position and a second position. In the first position, the scraper is adapted to be spaced apart from the surface to be cleaned, and in the second position, the scraper is adapted to abut against the surface to be cleaned. A water-absorbing member is disposed on the floor brush body, and in the length direction of the scraper, the water-absorbing member is located at at least one end of the scraper. The water-absorbing member is configured to abut against the surface to be cleaned at least when the scraper is in the second position, thereby reducing the range of water accumulation in the length direction of the scraper, improving the water stain residue problem caused by path deviation or turning operation in the prior art, and improving the overall cleaning effect of the cleaning device and the user experience.

[0041] The specific structure according to embodiments of this disclosure is described below.

[0042] A cleaning device according to an embodiment of the present disclosure includes: a body and a floor brush assembly 10.

[0043] Specifically, refer to Figure 1 As shown, the floor brush assembly 10 is rotatably mounted on the lower end of the body.

[0044] like Figure 1 , Figure 2 , Figure 3 As shown, the floor brush assembly 10 according to an embodiment of the present disclosure includes: a floor brush body 1, a scraper 2, and a water-absorbing component 3.

[0045] Specifically, refer to Figure 1 As shown, the scraper 2 is movably mounted on the floor brush body 1 in the vertical direction to switch between a first position and a second position, as follows. Figure 2 and Figure 3 As shown, in the first position, the scraper 2 is adapted to be spaced apart from the surface being cleaned, such as... Figure 4 and Figure 5 As shown, in the second position, the scraper 2 is adapted to abut against the surface being cleaned. The height difference between the first and second positions can be 15-25 mm.

[0046] The surface to be cleaned can be the ground. The abutment between the scraper 2 and the surface to be cleaned can be achieved by an interference fit (e.g., 2-5mm). The scraper 2 can also be located at the front end of the brush body 1.

[0047] Furthermore, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the water-absorbing component 3 is located on the brush body 1, along the length of the scraper 2 (e.g., ...). Figure 1 In the direction shown (a), the absorbent 3 is located at at least one end of the scraper 2, and the absorbent 3 is configured to abut against the surface being cleaned at least when the scraper 2 is in the second position.

[0048] Understandably, during the process from the first position to the second position, the cleaning device moves backward. At this time, the scraper 2 falls down until it contacts the surface to be cleaned at the second position. At this time, the water-absorbing component 3 also contacts the surface to be cleaned and begins to scrape away the water on the ground. During the backward pulling process, a certain amount of water scraped up will accumulate at the scraper 2. Due to the presence of the water-absorbing component 3, the water at the end of the scraper 2 with the absorbent component along its length will be absorbed, thereby reducing the range of water accumulation along the length of the scraper 2.

[0049] Therefore, when the cleaning equipment turns or moves forward, even if the movement trajectory of the roller brush 9 deviates somewhat from the original path of the scraper 2, the area where water accumulates along the length of the scraper 2 has been reduced by the water-absorbing component 3. This makes it easier for the roller brush 9 to cover and absorb the remaining water, thus significantly reducing the probability and area of ​​water stains appearing at corners. This design, through the synergistic effect of the water-absorbing component 3 and the scraper 2, controls the distribution range of accumulated water from the source, effectively improving the problem of water stain residue caused by path deviation or cornering operations in existing technologies, and enhancing the overall cleaning effect of the cleaning equipment and the user experience.

[0050] Preferred, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the water-absorbing element 3 is located at both ends of the scraper 2 along its length, thereby further reducing the range of water accumulation along the length of the scraper 2, further improving the water stain residue problem caused by path deviation or turning operation in the prior art, and improving the overall cleaning effect of the cleaning equipment and the user experience.

[0051] It should be noted that the scraper 2 can move vertically up and down in the vertical direction, in which case the length direction of the scraper 2 is perpendicular to the vertical direction. However, the movement of the scraper 2 is not limited to this. In some other embodiments of this disclosure, the scraper 2 can also rotate about an axis extending in the vertical direction along its length (left and right direction) to achieve its movement in the vertical direction.

[0052] The absorbent component 3 can be a structural component with inherent water-absorbing properties, such as a sponge, foamed rubber, or microfiber. These materials ensure that when the absorbent component 3 comes into contact with the surface being cleaned, it can both tightly adhere to the surface to effectively absorb moisture without causing scratches or excessive wear. Furthermore, the shape of the absorbent component 3 can be designed, for example, with a slightly curved contact surface to increase the contact area with the surface being cleaned and improve water absorption efficiency. Alternatively, the absorbent component 3 can be designed with an interference fit (e.g., 2-5mm).

[0053] The absorbent component 3 can also be constructed as a structural component with a suction function. For example, a suction channel connected to the absorbent component 3 can be provided inside the brush body 1, and this suction channel is connected to the negative pressure source of the cleaning equipment. When the absorbent component 3 comes into contact with the surface being cleaned, the suction force generated by the negative pressure source acts on the absorbent component 3 through the suction channel, allowing the absorbent component 3 to absorb surface moisture while simultaneously drawing the moisture into the suction channel and discharging it into the wastewater tank of the cleaning equipment. This structure of the absorbent component 3 with a suction function is particularly suitable for cleaning scenarios involving a large amount of standing water or stubborn stains, significantly improving water absorption efficiency and cleaning effect. Simultaneously, to ensure the suction effect, the contact area between the absorbent component 3 and the surface being cleaned can be designed with an interference fit to ensure a tight seal against the surface under negative pressure, preventing suction leakage.

[0054] Furthermore, such as Figure 1 As shown, the floor brush assembly 10 also includes a roller brush 9. The floor brush body 1 is located at the lower end of the main body and is rotatably connected to the lower end of the main body. The material of the floor brush body 1 includes, but is not limited to, metal, plastic, and a combination of the two. The roller brush 9 is rotatably mounted on the floor brush body 1. The rotation center line of the roller brush 9 extends along the length direction of the scraper 2, wherein the length direction of the scraper 2 can be left and right, which facilitates the roller brush 9 to roll in the back-and-forth direction to clean the surface being cleaned.

[0055] In some embodiments of this disclosure, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the floor brush assembly 10 includes: a wringer 4, which is disposed on the floor brush body 1. The wringer 4 and the absorber 3 are movable relative to each other in the horizontal direction. In the second position, in the length direction of the scraper 2, the wringer 4 is located on the side of the absorber 3 near the center line of the scraper 2 in the length direction. The wringer 4 is configured such that after the scraper 2 leaves the second position, the absorber 3 moves toward the wringer 4 to apply pressure to the absorber 3, and after the scraper 2 leaves the first position, the absorber 3 is released. It should be noted that the absorber 3 is a flexible component.

[0056] Specifically, the water-absorbing component 3 is movable relative to the water-squeezing component 4 along the length direction of the scraper 2 between a third position and a fourth position. When the scraper 2 is in the first position, the water-absorbing component 3 is in the third position. When the scraper 2 is in the second position, the water-absorbing component 3 is in the fourth position. The third position is located on the side of the fourth position closer to the center line of the scraper 2 along its length direction.

[0057] Understandably, when the scraper 2 is in the second position, the absorbent component 3 is in the fourth position. At this time, there is a certain gap between the squeezing component 4 and the absorbent component 3, allowing the absorbent component 3 to freely contact the surface being cleaned to perform the water absorption operation. When the scraper 2 disengages from the second position (e.g., during the transition from the second position to the first position), the absorbent component 3 moves towards the squeezing component 4 under the drive of the corresponding structure, i.e., from the fourth position to the third position. During this movement, the squeezing component 4 gradually comes into contact with the absorbent component 3 and applies pressure to it. Since the absorbent component 3 is usually made of a flexible material with water absorption properties, such as sponge or foam, the water absorbed inside the absorbent component 3 is squeezed out under the squeezing action of the squeezing component 4, thereby achieving dehydration of the absorbent component 3 so that it can complete the subsequent water absorption work.

[0058] When the scraper 2 disengages from the first position (e.g., when switching from the first position to the second position), the squeezing pressure is released, and the suction component 3 returns to its initial state, regaining its good water absorption capacity. It can also return to the fourth position with the movement of the scraper 2, ready for the next water absorption cycle. This design, which uses the position change of the scraper 2 to control the relative movement of the suction component 3 and the squeezing component 4 to achieve water squeezing and release, cleverly combines the working state of the scraper 2 with the maintenance state of the suction component 3. It can achieve automatic water squeezing of the suction component 3 without the need for additional complex drive devices, thereby improving the overall working efficiency and automation level of the floor brush assembly 10.

[0059] On the other hand, since the third position is located on the side of the fourth position near the center line of the scraper 2 along its length, that is, when the water-absorbing component 3 is at one end of the scraper 2 along its length, it can absorb water from the end of the scraper 2, and when it is near the center line along the length of the scraper 2, it can squeeze out water, and the squeezed-out water is concentrated in the middle area of ​​the scraper 2. When the floor brush assembly 10 moves forward, the roller brush 9 will preferentially contact and absorb this water in the middle of the scraper 2. Because the cleaning path of the roller brush 9 usually covers the middle of the scraper 2 and the main cleaning area, the squeezed-out water can be removed by the roller brush 9 in a timely and effective manner, and will not cause new, difficult-to-remove corner water stains on the ground when the cleaning equipment turns or changes direction due to water being located at the end of the scraper 2 and not being treated in time. This positional design makes the water absorption and squeezing process of the water-absorbing component 3 work well with the water absorption area of ​​the roller brush 9, further improving the cleaning effect of the floor brush assembly 10.

[0060] In some embodiments of this disclosure, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the squeezing member 4 is configured such that after the scraper 2 disengages from the second position, the suction member 3 moves a first preset distance toward the squeezing member 4 so that the squeezing member 4 applies a squeezing force to the suction member 3.

[0061] It is understandable that by moving the water-absorbing component 3 a first preset distance toward the water-squeezing component 4 so that the water-squeezing component 4 applies pressure to the water-absorbing component 3, the squeezed water can be better concentrated in the middle area of ​​the scraper 2, so that the squeezed water can be removed by the roller brush 9 in a timely and effective manner, further improving the cleaning effect of the floor brush assembly 10.

[0062] The first preset distance can be 6-10mm, such as 6mm, 7mm, 8mm or 10mm.

[0063] In some embodiments of this disclosure, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the dewatering component 4 includes a first extrusion section 41 and a second extrusion section 42, the first extrusion section 41 and the second extrusion section 42 being aligned along a first direction (e.g., Figure 1 and Figure 2 The compression space 43 is formed by spacing the space in the direction b shown, and the dimension of the compression space 43 along the first direction (as shown in the figure) is... Figure 5 K1 shown is smaller than the absorbent 3 along the first direction (e.g.) Figure 5 As shown in the figure (K2), after the scraper 2 leaves the second position, the water-absorbing member 3 moves toward the direction of the squeezing space 43, and after the scraper 2 leaves the first position, the water-absorbing member 3 moves toward the direction of the direction of the squeezing space 43.

[0064] It should be noted that the dimension of the compression space 43 along the first direction refers to the dimension between the two walls of the compression space 43 along the first direction, excluding the inlet.

[0065] It is understandable that the first squeezing part 41 and the second squeezing part 42 are configured to form a squeezing space 43, and the dimension of the squeezing space 43 along the first direction is smaller than the dimension of the absorbent 3 along that direction. When the absorbent 3 moves toward the squeezing space 43, it will be squeezed by the first squeezing part 41 and the second squeezing part 42, thereby fully squeezing out the water absorbed by the absorbent 3. This structural design can form a relatively uniform and effective squeezing force on the absorbent 3, avoiding the problem of water residue caused by incomplete local squeezing. After the scraper 2 is disengaged from the first position, the absorbent 3 moves toward the outside of the squeezing space 43. At this time, the squeezing force disappears, and the absorbent 3 can restore its deformation so that it can efficiently absorb water again in the next cleaning process.

[0066] In some embodiments of this disclosure, such as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the first extrusion section 41 and the second extrusion section 42 each have a guide slope 44 at one end facing each other. The guide slope 44 is located at the entrance of the extrusion space 43. Along the direction of relative movement between the water squeezing member 4 and the water suction member 3, and from outside the extrusion space 43 to inside the extrusion space 43, the guide slope 44 of the first extrusion section 41 and the guide slope 44 of the second extrusion section 42 extend inclined towards each other.

[0067] Understandably, the guide ramp 44 at the entrance of the squeezing space 43 guides the suction member 3 during its initial movement into the squeezing space 43. When the suction member 3 begins to enter the squeezing space 43, its edge first contacts the guide ramp 44. As the suction member 3 continues to move, the guide ramp 44 gradually guides it into the squeezing space 43. This design prevents the suction member 3 from getting stuck or colliding due to positional deviation when entering the squeezing space 43, ensuring that it enters the squeezing area smoothly and accurately, thus guaranteeing the stable operation of the squeezing process. Simultaneously, the inclined design of the guide ramp 44 allows the suction member 3 to gradually receive squeezing forces from the first squeezing section 41 and the second squeezing section 42 during its entry into the squeezing space 43, achieving a smooth transition of squeezing force and preventing damage to the suction member 3 or the squeezing section due to sudden large squeezing forces, further improving the reliability and service life of the entire squeezing structure.

[0068] In some embodiments of this disclosure, the floor brush body 1 has a water receiving tray (not shown) located below the squeezing member 4. The suction member 3 moves horizontally relative to the water receiving tray along the length of the scraper 2. On the one hand, the water receiving tray is used to receive water flowing out from the suction member 3 after it is squeezed. The water receiving tray has a drain outlet that is connected to the wastewater tank of the floor brush assembly 10. On the other hand, the water receiving tray can also isolate the suction member 3 from the surface to be cleaned, thereby preventing the suction member 3 from absorbing water from the surface to be cleaned and ensuring that it has good water absorption.

[0069] In some embodiments of this disclosure, such as Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the floor brush assembly 10 also includes: a lifting member 5, which is movably disposed on the floor brush body 1 in the vertical direction; a scraper 2 is disposed at the lower end of the lifting member 5; a squeezing member 4 is fixedly disposed on the lifting member 5; and a water-absorbing member 3 is movably disposed on the lifting member 5 in the horizontal direction, and the water-absorbing member 3 is configured to move synchronously with the lifting member 5 in the vertical direction.

[0070] Understandably, since the water-absorbing component 3 is constructed to move synchronously in the vertical direction with the lifting component 5, when the scraper 2 is in the second position, the water-absorbing component 3 is also in contact with the surface being cleaned in the fourth position, thus achieving water absorption at the end of the scraper 2 in the length direction. When the scraper 2 rises from the second position to the first position, the water-absorbing component 3 moves from the fourth position to the third position and gradually leaves the surface being cleaned. After the water-absorbing component 3 finishes squeezing out the water, it separates from the surface being cleaned, thus preventing the water-absorbing component 3 from absorbing water from the surface being cleaned at this time, ensuring that it has good water absorption, which is beneficial for the next water absorption at the end of the scraper 2 in the length direction.

[0071] In some embodiments of this disclosure, such as Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the lifting component 5 has one of a first sliding groove 51 and a first sliding pin 61; the floor brush assembly 10 also includes: a guide rail component 6; a water-absorbing component 3 is disposed at the lower end of the guide rail component 6, the other of the guide rail component 6 has a first sliding groove 51 and a first sliding pin 61, and the first sliding pin 61 is movably disposed in the first sliding groove 51 along the length direction of the first sliding groove 51.

[0072] It should be noted that the first sliding pin 61 can be elongated, cylindrical, etc. In this disclosure, the first sliding pin 61 is provided on the guide rail 6 and the first sliding groove 51 is provided on the lifting member 5. However, this disclosure is not limited to this. The first sliding pin 61 can be provided on the lifting member 5 and the first sliding groove 51 can be provided on the guide rail 6.

[0073] It is understandable that, since the first sliding pin 61 is located in the first sliding groove 51, when the lifting member 5 is raised or lowered, the upper and lower walls of the first sliding groove 51 limit the first sliding pin 61, thereby driving the guide rail member 6 to rise and fall synchronously with the lifting member 5, so as to realize the synchronous rise and fall of the water absorption member 3 and the lifting member 5. However, the method of realizing the synchronous rise and fall of the water absorption member 3 and the lifting member 5 in this disclosure is not limited to this.

[0074] The first sliding pin 61 is movably disposed in the first sliding groove 51 along the length direction of the first sliding groove 51, so that the water-absorbing component 3 can move relative to the lifting component 5 along the length direction of the scraper 2.

[0075] In some embodiments of this disclosure, such as Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the floor brush body 1 has one of a second sliding groove 11 and a second sliding pin 62; the floor brush assembly 10 also includes: a guide rail 6; the other of the guide rail 6 has a second sliding groove 11 and a second sliding pin 62, the water-absorbing member 3 is fixed to the lower end of the guide rail 6, and the guide rail 6 is movably disposed on the lifting member 5; along the length direction of the scraper 2, and from the center line of the length direction of the scraper 2 to the end of the scraper 2 with the water-absorbing member 3, the second sliding groove 11 extends downward at an angle, and the second sliding pin 62 is movably disposed in the second sliding groove 11 along the length direction of the second sliding groove 11.

[0076] It should be noted that the second sliding pin 62 can be elongated, cylindrical, etc. In this disclosure, the second sliding pin 62 is provided on the guide rail 6 and the second sliding groove 11 is provided on the floor brush body 1. However, this disclosure is not limited to this. The second sliding pin 62 can be provided on the floor brush body 1 and the second sliding groove 11 can be provided on the guide rail 6.

[0077] It is understandable that, through the cooperation of the second slide groove 11 and the second slide pin 62, when the guide rail 6 moves in the vertical direction, the guide rail 6 is driven to move in the length direction of the scraper 2 due to the limiting effect of the second slide groove 11 and the second slide pin 62, thereby realizing the movement of the water suction component 3 relative to the lifting component 5 in the length direction of the scraper 2. However, the method of realizing the movement of the water suction component 3 relative to the lifting component 5 in the length direction of the scraper 2 in this disclosure is not limited to this.

[0078] In some embodiments of this disclosure, such as Figure 10 and Figure 11 As shown, the lifting member 5 has an installation space 52 at one end along the length of the scraper 2; the guide rail 6 is movably disposed in the installation space 52, and the bottom of the installation space 52 has an open opening; at least part of the water suction member 3 passes through the open opening, the peripheral wall of the installation space 52 has a through hole 53, the second sliding pin 62 passes through and is supported in the through hole 53; the top wall surface of the installation space 52 abuts against the top surface of the guide rail 6.

[0079] Understandably, the installation space 52 provides stable guidance and support for the guide rail 6. The open design allows the absorbent 3 to extend smoothly and contact the surface to be cleaned, ensuring effective water absorption. The through hole 53 positions and supports the second sliding pin 62. When the guide rail 6 moves up and down under the action of the lifting component 5, the second sliding pin 62 can slide stably within the through hole 53, while simultaneously engaging with the second sliding groove 11 on the brush body 1 to guide the guide rail 6 to move along the length of the scraper 2.

[0080] The top wall of the installation space 52 abuts against the top surface of the guide rail 6, so that the movement of the lifting component 5 in the vertical direction can synchronously drive the guide rail 6 to move in the vertical direction. This is also a way to achieve synchronous lifting of the water suction component 3 and the lifting component 5.

[0081] It should be noted that, for example Figure 10 and Figure 11 As shown, a cover plate 55 is provided on the side of the installation space 52 away from the open opening. The cover plate 55 covers the side of the installation space 52 away from the open opening, and the wall surface of the cover plate 55 facing the installation space 52 forms the top wall surface of the installation space 52. In some embodiments of this disclosure, such as Figure 3 and Figure 6 As shown, the floor brush assembly 10 also includes a first reset member 7, which is used to drive the water suction member 3 to move toward the water squeezing member 4, that is, the first reset member 7 is used to drive the water suction member 3 to move from the fourth position to the third position.

[0082] Understandably, the first reset member 7 is configured to provide a continuous reset driving force for the water-absorbing member 3, ensuring that during the cleaning process, the water-absorbing member 3 can automatically return to the third position that cooperates with the water-squeezing member 4, thereby ensuring the reliable execution of the water-squeezing function.

[0083] In some embodiments of this disclosure, such as Figure 6 , Figure 8 , Figure 10 and Figure 12 As shown, the floor brush assembly 10 also includes: a lifting component 5, a drive mechanism 81, a connecting rod 82, and a sliding plate 83.

[0084] The lifting component 5 is movably mounted on the floor brush body 1 in the vertical direction, and the scraper 2 is mounted on the lower end of the lifting component 5; the drive mechanism 81 is mounted on the floor brush body 1; the connecting rod 82 is connected to the drive mechanism 81, and the drive mechanism 81 is used to drive the connecting rod 82 to be rotatably mounted on the floor brush body 1. The rotation axis of the connecting rod 82 extends along the first direction, and the connecting rod 82 is fixedly provided with a connecting arm 821. The connecting arm 821 protrudes from the outer circumferential surface of the connecting rod 82 and rotates between the first rotation position and the second rotation position. The first rotation position and the second rotation position are spaced apart in the length direction of the scraper 2, and the first direction, the vertical direction and the length direction of the scraper 2 are perpendicular to each other; the slide plate 83 is connected to the lifting component 5 in a transmission manner; in the first rotation position, the scraper 2 is located in the first position, and in the second rotation position, the scraper 2 is located in the second position.

[0085] It is understandable that the drive mechanism 81 drives the connecting rod 82 to rotate around the axis in the first direction, which can drive the connecting arm 821 to switch between the first rotation position and the second rotation position in the length direction of the scraper 2. The rotation of the connecting arm 821 can be converted into the movement of the slide plate 83 along the length direction of the scraper 2, and the movement of the slide plate 83 along the length direction of the scraper 2 can be converted into the movement of the scraper 2 along the length direction of the scraper 2.

[0086] This transmission mechanism, through the linkage 82, connecting arm 821, and slide plate 83, cleverly transforms the rotational motion of the drive mechanism 81 into the up-and-down lifting motion of the scraper 2. It has a compact structure and reliable transmission, and can accurately control the switching of the scraper 2 between the working and non-working positions, effectively improving the cleaning efficiency and service life of the floor brush assembly 10.

[0087] It should be noted that the drive mechanism 81 can be a drive motor. The first rotation position and the second rotation position are at the same horizontal height, thereby avoiding additional torque or jamming caused by the height difference during the rotation of the connecting arm 821 driven by the drive mechanism 81, and ensuring the smoothness and stability of the transmission of the connecting rod 82.

[0088] The sliding plate 83 and the connecting arm 821 can be movably connected in the following ways: such as Figure 6 As shown, the slide plate 83 is movable along the length direction of the scraper 2. The slide plate 83 has a strip hole 831, and the connecting arm 821 has a transmission pin 822. The strip hole 831 extends in the vertical direction, and the transmission pin 822 is movably disposed in the strip hole 831 along the length direction of the strip hole 831.

[0089] Since the first and second rotation positions are at the same horizontal height, when moving from the first to the second rotation position, the transmission pin 822 will move downward first and then upward. Through the above-mentioned movable connection between the slide plate 83 and the connecting arm 821, the transmission between the slide plate 83 and the connecting arm 821 can be realized without the slide plate 83 moving up and down. This makes the movement trajectory of the slide plate 83 only in one direction, simplifies the transmission relationship between the slide plate 83, the connecting arm 821 and the lifting component 5, and reduces the design difficulties and movement jamming problems caused by the compound motion of the slide plate 83.

[0090] In some embodiments of this disclosure, such as Figure 12 As shown, the floor brush body 1 has a limiting groove, both ends of which are open in the vertical direction. The lifting member 5 is movably disposed in the limiting groove. The sliding plate 83 is provided with a third sliding pin 832, and the lifting member 5 has a third sliding groove 54. The third sliding groove 54 includes a first groove segment 541 and a second groove segment 542 that are interconnected. Along the length direction of the scraper 2 and from the first rotation position to the second rotation position, the first groove segment 541 extends upward at an angle, and the second groove segment 542 is disposed at the upper end of the first groove segment 541 and extends away from the first groove segment 541 along the length direction of the scraper 2.

[0091] Understandably, the first groove segment 541 is designed so that, during the initial stage of the connecting arm 821 rotating from the first rotational position to the second rotational position, when the sliding plate 83 is moved by the transmission pin 822, the relative sliding of the third sliding pin 832 within the first groove segment 541 forces the lifting member 5 to move downward within the limiting groove, thereby achieving the descent of the scraper 2. This allows it to better conform to the surface of the roller brush 9, enhancing the scraping effect on the dirt attached to the roller brush 9. When the connecting arm 821 rotates to a certain angle, the third sliding pin 832 enters the second groove segment 542. At this time, as the sliding plate 83 continues to move, the third sliding pin 832 slides along the length of the scraper 2 within the second groove segment 542, locking the lifting member 5 at this position and preventing it from moving upward. This keeps the scraper 2 in contact with the surface of the roller brush 9, ensuring the stability and continuity of the scraping process.

[0092] In some embodiments of this disclosure, such as Figure 10 As shown, the floor brush body 1 is provided with a second reset member 84, which is connected to the slide plate 83 and is used to drive the slide plate 83 to move so that the third sliding pin 832 moves from the second groove section 542 to the first groove section 541.

[0093] Understandably, the second reset member 84 provides a continuous driving force to the slide plate 83 when the connecting arm 821 resets from the second rotation position to the first rotation position, causing the slide plate 83 to move back to its initial position. When the connecting arm 821 begins to reset and rotate, the transmission pin 822 drives the slide plate 83 to move in the opposite direction. At this time, under the action of the second reset member 84, the third sliding pin 832 can smoothly exit from the second groove 542 and enter the first groove 541. As the slide plate 83 moves further, the third sliding pin 832 slides relative to the first groove 541. Due to the upward tilting structure of the first groove 541, it drives the lifting member 5 to move upward in the limiting groove, thereby moving the scraper 2 away from the surface of the roller brush 9. This avoids unnecessary wear caused by the scraper 2 continuously contacting the roller brush 9 when not in operation, and also provides sufficient space for the normal rotation of the roller brush 9 and subsequent cleaning work. For example, when the cleaning equipment completes the cleaning task or the roller brush 9 needs maintenance, the connecting arm 821 resets, the second reset component 84 drives the slide plate 83 to move, so that the scraper 2 is automatically lifted, effectively protecting the scraper 2.
