Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a floor brush and cleaning equipment. Background Technology

[0002] In related technologies, the brush structure of floor scrubbers incorporates a squeegee to reduce water residue. This squeegee is typically fixed to the lower part of the brush and relies on its elasticity to maintain continuous contact with the floor. However, this fixed installation structure results in the squeegee being under constant pressure both in standby mode (brush placed on the floor) and during operation (continuous friction with the floor). Over time, this leads to decreased elasticity and reduced sealing between the squeegee and the floor, resulting in incomplete water removal and watermarks. Utility Model Content

[0003] In view of this, the present invention aims to provide a floor brush that can reduce the risk of scraper elastic failure and ensure its contact seal with the ground.

[0004] The first aspect of this utility model provides a floor brush for cleaning a surface to be cleaned, comprising: A floor brush body, wherein a roller brush is provided on the floor brush body; A scraper assembly is connected to the main body of the floor brush. In the forward direction of the floor brush body, the scraper assembly is located behind the roller brush. The scraper assembly includes a scraper component and a drive component, and the scraper component is connected to the main body of the floor brush. The driving component includes a driving plate, a transmission component, and a driver. The driving plate is in contact with the scraper component. The transmission component is located between the driving plate and the driver. The driver drives the driving plate and the scraper component to swing relative to the floor brush body through the transmission component so that the scraper component moves closer to or away from the surface to be cleaned.

[0005] This configuration, through a drive unit consisting of a driver, transmission components, and a drive plate, enables active control of the scraper's working state, transforming it from passively subjected to pressure to actively controlled. This allows the scraper to be lifted off the ground when not in use, fundamentally avoiding material fatigue and elasticity degradation caused by long-term static pressure, significantly extending the scraper's service life. The transmission components, as intermediate transmission mechanisms, ensure the controllability and switching of the driver's actions, providing the scraper with a reasonable downward pressure during operation. This pressure ensures effective sealing between the scraper and the ground to remove water stains while preventing abnormal scraper edge function due to excessive pressure, thus ensuring a continuous and stable cleaning effect and eliminating water residue. The drive plate, as the direct acting element, evenly transmits power to the scraper components, ensuring the overall stability of its force and movement, further improving the reliability and consistency of the scraping and sealing.

[0006] In some embodiments, the scraper component includes a scraper body and a connecting plate. The connecting plate is connected to the scraper body and is pivotally connected to the floor brush body at both ends in the width direction of the floor brush body. The pivot axis of the connecting plate is arranged along the width direction of the floor brush body, and the side of the connecting plate away from the scraper body is connected to the drive plate.

[0007] This configuration, with the connecting plate connected to the scraper body, separates the scraping function from the structural support function, ensuring a stable and efficient transmission path for the driving force and avoiding stress concentration. The connecting plate is pivotally connected to the brush body at both ends along its width, allowing the scraper component to swing around a single axis. This ensures the scraper body remains in parallel contact with the ground during lifting or pressing, achieving uniform scraping and effective sealing, eliminating localized water residue. Furthermore, the low-friction pivoting motion significantly improves the reliability of the action and the overall lifespan of the mechanism compared to relying solely on elastic deformation. The side of the connecting plate furthest from the scraper body is connected to the drive plate, allowing the force generated by the drive components to be efficiently applied to the scraper component through leverage, thus achieving stable and controllable oscillation with minimal driving force.

[0008] In some embodiments, a support portion is provided on one side of the scraper body adjacent to the connecting plate, the support portion extending along the width direction of the brush body, and the connecting plate contacting the support portion.

[0009] This design provides a support portion on the side of the scraper body adjacent to the connecting plate, offering a locally reinforced stress point for the flexible scraper body. This effectively prevents excessive local deformation caused by the pressure from the connecting plate, ensuring efficient transmission of driving force and stability of the scraping effect of the scraper body. The support portion extends along the width of the brush body, allowing it to evenly distribute the force applied by the connecting plate onto the scraper body, thereby ensuring uniformity of the contact pressure between the scraper working surface and the ground.

[0010] In some embodiments, the upper surface of the support portion is provided with a plurality of mounting protrusions, the plurality of mounting protrusions are arranged at intervals in the width direction of the floor brush body, the connecting plate is provided with a plurality of connecting holes, the mounting protrusions can be engaged in the connecting holes, and the plurality of mounting protrusions correspond one-to-one with the plurality of connecting holes.

[0011] This design, with multiple mounting protrusions on the upper surface of the support, provides clear positioning and force points for the connection. By arranging these mounting protrusions at intervals along the width of the brush body, the force is evenly distributed along the width of the scraper, effectively preventing the scraper body from twisting and deforming, and ensuring the uniformity of the wiping seal. By setting connecting holes that can mate with the mounting protrusions and locking the protrusions in the holes, a tool-free quick-assembly and disassembly structure is formed, greatly simplifying the scraper body replacement process and improving the product's maintainability. The precise design of multiple mounting protrusions corresponding one-to-one with multiple connecting holes eliminates assembly errors, ensures the uniqueness and consistency of the installation position, and thus stably maintains the product's design performance and cleaning effect.

[0012] In some embodiments, the transmission element is a transmission rod, one end of which is connected to the output shaft of the driver, and the other end of which is pivotally connected to the drive plate.

[0013] This configuration, by specifically designating the transmission component as a transmission rod, leverages its rigidity to achieve efficient, direct, and reliable power transmission from the driver to the drive plate. One end of the transmission rod is connected to the output shaft of the driver, establishing a shorter transmission chain and improving the system's response speed and control precision. By pivoting the other end of the transmission rod to the drive plate, the linear reciprocating motion of the transmission rod is cleverly converted into the oscillation required by the drive plate, while avoiding motion interference and ensuring the smoothness and durability of the entire mechanism's operation.

[0014] In some embodiments, the end of the transmission rod connected to the output shaft of the driver is provided with a sleeve portion, the sleeve portion is sleeved on the output shaft, and the sleeve portion is provided with a plurality of connecting grooves inside, the connecting grooves extend along the axial direction of the output shaft, and the plurality of connecting grooves are evenly spaced in the circumferential direction of the output shaft. The output shaft is provided with a plurality of connecting protrusions, the plurality of connecting protrusions are evenly spaced in the circumferential direction of the output shaft, and the plurality of connecting protrusions correspond one-to-one with the plurality of connecting grooves.

[0015] This configuration, by setting a sleeve at the end of the transmission rod and fitting it onto the output shaft, achieves the basic transmission and bearing of the drive's rotational motion. A connecting groove extending axially along the output shaft is set inside the sleeve, cooperating with a connecting protrusion on the output shaft, creating a floating connection that effectively transmits torque while allowing for slight axial sliding. This effectively compensates for manufacturing and assembly tolerances, preventing the mechanism from jamming. By arranging the connecting groove and connecting protrusion at even intervals around the output shaft, symmetrical and balanced torque transmission is achieved, avoiding uneven wear and improving the smoothness of motion and component lifespan. The one-to-one correspondence between multiple connecting protrusions and multiple connecting grooves ensures unique assembly correctness, guaranteeing the consistency and reliability of product performance.

[0016] In some embodiments, the drive plate has a first notch that extends along the width of the brush body and penetrates the drive plate vertically. The connecting plate has a second notch at a position corresponding to the first notch, and the first and second notches are interconnected. The driving component further includes a driving seat, which is mounted on the driving plate and located at the first notch. The driving seat is rotatable relative to the driving plate, and the rotation axis of the driving seat extends along the width direction of the floor brush body. The transmission rod is pivotally connected to the driving seat.

[0017] This design, with a notch extending along the width and running vertically through the drive plate, provides the necessary structural space for the installation and free rotation of the drive seat. By introducing the drive seat and installing it at the notch, an independent rotating component is added, realizing the decomposition of motion functions. The drive seat can rotate relative to the drive plate, and the rotation axis extends along the width direction, effectively absorbing and compensating for possible spatial alignment errors in the transmission chain, eliminating harmful internal stresses, and ensuring smooth transmission. By pivoting the transmission rod to the drive seat and combining it with the rotation function of the drive seat, the reliability, durability, and motion accuracy of the entire floating mechanism are improved.

[0018] In some embodiments, the drive plate is provided with a connector, the connector is located around the first notch, the connector has an opening on the side facing the first notch, the drive plate is provided with a connecting pin, one end of the connecting pin passes through the opening and extends into the connector.

[0019] This configuration, by setting a connecting seat on the drive plate located around the first notch, concentrates the rotational support function on an independent and optimizable structure, enhancing local strength and simplifying manufacturing. By having an opening on the side of the connecting seat facing the first notch, a radially embedded channel is provided for the installation of the drive seat, enabling convenient lateral assembly. By setting a connecting pin on the drive seat, the rotation axis is clearly defined, providing a precise geometric reference for the rotation of the drive seat. By having one end of the connecting pin extend into the connecting seat through the opening, a stable bearing structure circumferentially enclosed is formed, ensuring that the drive seat can only rotate smoothly around the predetermined axis when bearing working loads, avoiding any unnecessary swaying. Thus, a highly reliable and high-precision rotary connection is achieved in a compact space.

[0020] In some embodiments, the number of connecting seats is two, and the two connecting seats are symmetrically arranged on both sides of the first notch in the width direction of the brush body. The drive seat is provided with two connecting pins, and the two connecting pins are respectively located in the two connecting seats.

[0021] This configuration, with two connecting seats, provides multi-point stability constraints for the drive seat, effectively preventing swaying and tilting during operation. By symmetrically positioning the two connecting seats on both sides of the first notch in the width direction of the brush body, absolute balance of support force and precise stability of the rotation axis are ensured, fundamentally avoiding uneven loading and unilateral wear. By correspondingly setting two connecting pins on the drive seat, precisely matching the two connecting seats, a unique rotation center is defined, and a high-rigidity, high-stability simply supported beam rotation support structure is constructed. This structure can efficiently resist overturning moments and evenly distribute the force, thereby greatly improving the motion accuracy, reliability, and service life of the entire transmission connection point.

[0022] In some embodiments, the drive seat is provided with a groove that extends along the width direction of the floor brush body, and the end of the transmission rod away from the driver is provided with a drive pin that extends into the groove, and the transmission rod is movable within the groove.

[0023] This configuration, by setting a groove on the drive seat that extends along the width of the brush body, provides a precise and constrained movement path for the end of the transmission rod. By setting a drive pin at the end of the transmission rod and having it extend into the groove, a simple and efficient force transmission interface is constructed, converting the linear thrust of the transmission rod into pressure on the groove wall of the drive seat, thereby generating rotational torque. The transmission rod can move within the groove and can automatically adapt to the dynamic changes in the effective distance between the transmission rod and the rotation center of the drive seat during operation, completely avoiding motion interference and jamming, and ensuring smooth power transmission.

[0024] In some embodiments, the drive pin is rotatable relative to the transmission rod.

[0025] This configuration, by allowing the drive pin to rotate relative to the transmission rod, transforms the contact friction between the drive pin and the slide wall from sliding friction to rolling friction, reducing motion resistance and component wear, and improving transmission efficiency and durability.

[0026] The second aspect of this utility model provides a cleaning device, including a floor brush as described in any one of the first aspects. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] It should be noted that the floor brush in this utility model can be applied to cleaning equipment such as floor scrubbers and vacuum cleaners.

[0038] An embodiment of the first aspect of this utility model provides a floor brush for cleaning a surface to be cleaned, including a floor brush body 100 and a scraper assembly 300. The floor brush body 100 is provided with a roller brush 200, and the scraper assembly 300 is connected to the floor brush body 100. In the forward direction of the floor brush body 100, the scraper assembly 300 is located behind the roller brush 200. The scraper assembly 300 includes a scraper component 2 and a driving component 1, and the scraper component 2 is connected to the floor brush body 100.

[0039] See Figure 1 As shown, the roller brush 200 is arranged on the floor brush body 100 in the left-right direction. The forward direction of the floor brush body 100 is the front, and the backward direction of the floor brush body 100 is the rear. The scraper assembly 300 is located on the rear side of the roller brush 200.

[0040] Above the scraper assembly 300 is the air inlet of the floor brush body 100. It should be noted that when the floor brush body moves backward, the scraper assembly 300 lifts up to reduce the contact pressure with the bottom surface. Conversely, when the floor brush body moves forward, the scraper assembly 300 lowers to contact the bottom surface, pushing the water stains on the ground forward and drawing them into the air inlet in conjunction with the air inlet.

[0041] The drive component 1 includes a drive plate 11, a transmission component 12, and a driver 13. The drive plate 11 is in contact with the scraper component 2. The transmission component 12 is located between the drive plate 11 and the driver 13. The driver 13 drives the drive plate 11 and the scraper component 2 to swing relative to the floor brush body 100 through the transmission component 12 so that the scraper component 2 moves closer to or away from the surface to be cleaned.

[0042] See Figure 1 and Figure 2 As shown, the driver 13 is installed inside the brush body 100. The output shaft of the driver 13 faces the scraper component 2. The output shaft of the driver 13 is connected to the upper end of the transmission component 12. The lower end of the transmission component 12 is connected to the drive plate 11. The drive plate 11 is connected to the scraper component 2. For example, the drive plate 11 and the scraper component 2 are detachably connected by bolts, magnetic attraction or snap-fit.

[0043] This configuration, through the drive component 1 consisting of the driver 13, transmission component 12, and drive plate 11, enables active control of the working state of the scraper component 2, transforming it from passively subjected to pressure to actively controlled. This allows the scraper to be lifted off the ground when not in operation, fundamentally avoiding material fatigue and elasticity decay caused by long-term static pressure, and significantly extending the scraper's service life. The transmission component 12, as an intermediate transmission mechanism, ensures the controllability and switching of the driver 13's actions, enabling the scraper to obtain a reasonable downward pressure during operation. This pressure ensures effective sealing between the scraper and the ground to remove water stains, while also preventing abnormal scraper edge function due to excessive pressure, thus ensuring a continuous and stable cleaning effect and eliminating water stain residue. The drive plate 11, as a direct acting element, evenly transmits power to the scraper component 2, ensuring the overall stability of its force and movement, further improving the reliability and consistency of the scraping and sealing.

[0044] In some embodiments, the scraper component 2 includes a scraper body 21 and a connecting plate 22. The connecting plate 22 is connected to the scraper body 21. The two ends of the connecting plate 22 are pivotally connected to the floor brush body 100 in the width direction. The pivot axis of the connecting plate 22 is arranged along the width direction of the floor brush body 100. The side of the connecting plate 22 away from the scraper body 21 is connected to the drive plate 11.

[0045] See Figure 3 As shown, the connecting plate 22 is located at the rear end of the scraper body 21. The connecting plate 22 and the scraper body 21 can be detachably connected by bolts, magnetic attraction, or snap-fit. The connecting plate 22 extends in the left-right direction, and the left and right ends of the connecting plate 22 are pivotally connected to the floor brush body 100 via pivot shafts. In other words, the connecting plate 22 can swing back and forth around the pivot shafts. The dimensions of the connecting plate 22 in the left-right direction are the same as those of the drive plate 11 in the left-right direction, and the connecting plate 22 is located below the drive plate 11. The drive plate 11 and the connecting plate 22 are connected by bolts, magnetic attraction, or snap-fit.

[0046] This configuration, with the connecting plate 22 connected to the scraper body 21, separates the scraping function from the structural support function, ensuring a stable and efficient transmission path for the driving force and avoiding stress concentration. The connecting plate 22 is pivotally connected to the floor brush body 100 at both ends along its width, allowing the scraper component 2 to swing around a single axis. This ensures that the scraper body 21 remains in parallel contact with the ground during lifting or pressing, achieving uniform scraping and effective sealing, eliminating localized water residue, and significantly improving the reliability of the action and the overall service life of the mechanism compared to relying solely on elastic deformation. The side of the connecting plate 22 furthest from the scraper body 21 is connected to the drive plate 11, allowing the force generated by the drive component 1 to be efficiently applied to the scraper component 2 through leverage, thus achieving stable and controllable oscillation with minimal driving force.

[0047] In some embodiments, a support portion 211 is provided on one side of the scraper body 21 adjacent to the connecting plate 22. The support portion 211 extends along the width direction of the floor brush body 100, and the connecting plate 22 is in contact with the support portion 211.

[0048] See Figure 4 As shown, the support portion 211 extends in the left-right direction, and the dimension of the support portion 211 in the left-right direction is less than or equal to the dimension of the scraper body 21 in the left-right direction. The outer contour of the cross-section of the scraper body 21 is generally C-shaped, and the support portion 211 and the inner top surface of the scraper body 21 have a gap in the vertical direction, and the connecting plate 22 is located in the gap.

[0049] It should be noted that, for example, at the junction of the lower end face of the connecting plate 22 and the upper end face of the support portion 211, the connecting plate 22 and the support portion 211 can be detachably connected by means of magnetic attraction, bolt connection or snap-fit.

[0050] With this configuration, a support portion 211 is provided on the side of the scraper body 21 adjacent to the connecting plate 22, providing a locally reinforced stress point for the flexible scraper body 21. This effectively prevents excessive local deformation caused by the pressure of the connecting plate 22, ensuring efficient transmission of driving force and stability of the scraping effect of the scraper body 21. The support portion 211 extends along the width direction of the floor brush body 100, enabling it to evenly distribute the force applied by the connecting plate 22 onto the scraper body 21, thereby ensuring the uniformity of the contact pressure between the scraper working surface and the ground.

[0051] In some embodiments, the upper surface of the support portion 211 is provided with a plurality of mounting protrusions 212, the plurality of mounting protrusions 212 are arranged at intervals in the width direction of the floor brush body 100, the connecting plate 22 is provided with a plurality of connecting holes, the mounting protrusions 212 can be locked in the connecting holes, and the plurality of mounting protrusions 212 correspond one-to-one with the plurality of connecting holes.

[0052] See Figure 4 and Figure 5 As shown, multiple mounting protrusions 212 are located on the upper end face of the support portion 211, and the multiple mounting protrusions 212 are evenly spaced in the left and right directions. The connecting plate 22 is provided with multiple mounting holes 221, the inner contour of the mounting holes 221 is adapted to the outer contour of the mounting protrusions 212, and the multiple mounting holes 221 correspond one-to-one with the multiple mounting protrusions 212.

[0053] For example, multiple mounting protrusions 212 are integrally formed with the support portion 211. For instance, when the scraper body 21 is made of rubber, the mounting protrusions 212 and the support portion 211 are integrally injection molded. This improves the structural strength of the mounting protrusions 212, thereby ensuring the connection stability between the connecting plate 22 and the scraper body 21.

[0054] This design, with multiple mounting protrusions 212 on the upper surface of the support 211, provides clear positioning and force points for the connection. By arranging these mounting protrusions 212 at intervals along the width of the brush body 100, the force is evenly distributed along the width of the scraper, effectively preventing the scraper body 21 from twisting and deforming, and ensuring the uniformity of the wiping seal. By setting connecting holes that can mate with the mounting protrusions 212 and locking the protrusions in the holes, a tool-free quick disassembly and assembly structure is formed, which greatly simplifies the replacement process of the scraper body 21 and improves the maintainability of the product. The precise design of multiple mounting protrusions 212 corresponding to multiple connecting holes eliminates assembly errors, ensures the uniqueness and consistency of the installation position, and thus stably maintains the product's design performance and cleaning effect.

[0055] In some embodiments, the transmission member 12 is a transmission rod, one end of which is connected to the output shaft of the driver 13, and the other end of which is pivotally connected to the drive plate 11.

[0056] For example, see Figure 6 As shown, the transmission component 12 can be a transmission rod, with its upper end connected to the output shaft of the driver 13 and its lower end pivotally connected to the drive plate 11. In this way, by specifically designing the transmission component 12 as a transmission rod, and utilizing its characteristics as a rigid component, efficient, direct, and reliable power transmission from the driver 13 to the drive plate 11 is achieved. One end of the transmission rod is connected to the output shaft of the driver 13, establishing a shorter transmission chain and improving the system's response speed and control accuracy. By pivoting the other end of the transmission rod to the drive plate 11, the linear reciprocating motion of the transmission rod is cleverly converted into the oscillation required by the drive plate 11, while avoiding motion interference and ensuring the smoothness and durability of the entire mechanism's operation.

[0057] For example, see Figure 6As shown, the end of the transmission rod connected to the output shaft of the driver 13 is provided with a sleeve portion 121. The sleeve portion 121 is sleeved on the output shaft, and the sleeve portion 121 is provided with a plurality of connecting grooves 1211 inside. The connecting grooves 1211 extend along the axial direction of the output shaft, and the plurality of connecting grooves 1211 are evenly spaced in the circumferential direction of the output shaft. The output shaft is provided with a plurality of connecting protrusions, which are evenly spaced in the circumferential direction of the output shaft, and the plurality of connecting protrusions correspond one-to-one with the plurality of connecting grooves 1211.

[0058] It should be noted that multiple connecting protrusions are integrally formed with the output shaft of the driver 13, thereby improving the connection stability between the connecting protrusions and the sleeve portion 121.

[0059] Furthermore, by setting a sleeve portion 121 at the end of the transmission rod and fitting it onto the output shaft, the basic transmission and bearing of the rotational motion of the driver 13 are realized. By setting a connecting groove 1211 extending axially along the output shaft inside the sleeve portion 121 and cooperating with the connecting protrusion on the output shaft, a floating connection that can effectively transmit torque and allow for slight axial sliding is constructed, effectively compensating for manufacturing and assembly tolerances and preventing the mechanism from jamming. By arranging the connecting groove 1211 and the connecting protrusion at uniform intervals around the output shaft, symmetrical and balanced transmission of torque is achieved, avoiding uneven wear and improving the smoothness of motion and the life of components. The one-to-one correspondence between multiple connecting protrusions and multiple connecting grooves 1211 ensures the unique correctness of the assembly and guarantees the consistency and reliability of product performance.

[0060] In some embodiments, the drive plate 11 is provided with a first notch 111, which extends along the width direction of the brush body 100 and penetrates the drive plate 11 in the vertical direction. The drive component 1 also includes a drive seat 14, which is mounted on the drive plate 11 and located at the first notch 111. The drive seat 14 is rotatable relative to the drive plate 11, and the rotation axis of the drive seat 14 extends along the width direction of the brush body 100. The transmission rod is pivotally connected to the drive seat 14.

[0061] See Figure 7 As shown, the first notch 111 extends in the left-right direction and penetrates the drive plate 11 in the up-down direction. It should be noted that the connecting plate 22 has a second notch at a position corresponding to the first notch 111. The shape and size of the second notch are the same as those of the first notch 111. The first notch 111 and the second notch are interconnected. The drive seat 14 is located within the first notch 111 and the second notch; in other words, the drive seat 14 can rotate at the notch formed by the first notch 111 and the second notch.

[0062] This configuration, by providing a notch extending along the width direction and penetrating vertically on the drive plate 11, provides the necessary structural space for the installation and free rotation of the drive seat 14. By introducing the drive seat 14 and installing it at the notch, an independent rotating component is added, realizing the decomposition of motion functions. The drive seat 14 is rotatable relative to the drive plate 11, and the rotation axis extends along the width direction, effectively absorbing and compensating for possible spatial alignment errors in the transmission chain, eliminating harmful internal stresses, and ensuring smooth transmission. By pivoting the transmission rod to the drive seat 14 and combining it with the rotation function of the drive seat 14, the reliability, durability, and motion accuracy of the entire floating mechanism are improved.

[0063] In some embodiments, the drive plate 11 is provided with a connecting seat 15, which is located around the first notch 111. The connecting seat 15 has an opening on one side facing the first notch 111. The drive seat 14 is provided with a connecting pin 141, one end of which passes through the opening and extends into the connecting seat 15.

[0064] See Figure 7 As shown, the connector 15 is located above the drive plate 11, and the lower end of the connector 15 and the side facing the notch have openings. Connecting pins 141 are provided on the left and right sides of the drive plate 14, and the connecting pins 141 can be inserted into the connector 15.

[0065] It should be noted that when the drive plate 11 is connected to the connecting plate 22, the opening below the connecting seat 15 is closed by the connecting plate 22. In other words, when the drive plate 11 and the connecting plate 22 are connected, the connecting seat 15 only has an opening on the side facing the notch.

[0066] For example, see Figure 2 As shown, there are two connecting seats 15. The two connecting seats 15 are symmetrically arranged on both sides of the first notch 111 in the width direction, i.e., the left and right direction, of the brush body. The drive seat 14 has two connecting pins 141 on the left and right sides, and the two connecting pins 141 are located in the two connecting seats 15 respectively.

[0067] This configuration, by providing a connecting seat 15 on the drive plate 11 located around the first notch 111, concentrates the rotational support function on an independent and optimizable structure, enhancing local strength and simplifying manufacturing. By having an opening on the side of the connecting seat 15 facing the first notch 111, a radially embedded channel is provided for the installation of the drive seat 14, enabling convenient lateral assembly. By providing a connecting pin 141 on the drive seat 14, the rotation axis is clearly defined, providing a precise geometric reference for the rotation of the drive seat 14. By having one end of the connecting pin 141 extend into the connecting seat 15 through the opening, a stable bearing structure that is circumferentially wrapped is formed, ensuring that the drive seat 14 can only rotate smoothly around the predetermined axis when bearing working loads, avoiding any unnecessary shaking. Thus, a highly reliable and high-precision rotational connection is achieved in a compact space.

[0068] By setting the number of connecting seats 15 to two, a multi-point stable constraint is provided for the drive seat 14, effectively preventing it from shaking and tilting during operation. By symmetrically arranging the two connecting seats 15 on both sides of the first notch 111 in the width direction of the brush body, the absolute balance of the supporting force and the precise stability of the rotation axis are ensured, fundamentally avoiding uneven loading and unilateral wear. By setting two connecting pins 141 on the drive seat 14 to precisely match the two connecting seats 15, a unique rotation center is defined, and a high-rigidity, high-stability simply supported beam rotation support structure is constructed. This structure can efficiently resist overturning moment and evenly distribute the force, thereby greatly improving the motion accuracy, reliability, and service life of the entire transmission connection point.

[0069] In some embodiments, the drive base 14 is provided with a slide groove 142, which extends along the width direction of the floor brush body 100. The end of the transmission rod away from the driver 13 is provided with a drive pin 122, which extends into the slide groove 142 and the transmission rod is movable within the slide groove 142.

[0070] See Figure 8 As shown, the slide 142 is opened in the middle of the drive seat 14 and extends in the left and right direction. The lower end of the transmission rod is provided with a drive pin 122, which extends into the slide 142 and can move left and right in the slide 142.

[0071] Optionally, the drive pin 122 is rotatable relative to the transmission rod. By making the drive pin 122 rotatable relative to the transmission rod, the contact friction between the drive pin 122 and the wall of the groove 142 is changed from sliding friction to rolling friction, which reduces motion resistance and component wear, and improves transmission efficiency and durability.

[0072] This configuration, by providing a groove 142 extending along the width of the brush body 100 on the drive seat 14, provides a precise and constrained movement path for the end of the transmission rod. By providing a drive pin 122 at the end of the transmission rod and having it extend into the groove 142, a simple and efficient force transmission interface is constructed, converting the linear thrust of the transmission rod into pressure on the wall of the groove 142 of the drive seat 14, thereby generating rotational torque. The transmission rod can move within the groove 142 and can automatically adapt to the dynamic changes in the effective distance between the transmission rod and the rotation center of the drive seat 14 during operation, completely avoiding motion interference and jamming, and ensuring smooth power transmission.

[0073] The second aspect of this utility model provides a cleaning device, including a floor brush as described in any of the first aspects.

[0074] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications or equivalent substitutions made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
