[0002] In existing technologies, floor scrubbers typically have squeegees on the front and / or rear of the roller brush.

[0024] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0025] The following is for reference. Figures 1-11 Description of a scraper assembly 100 according to an embodiment of the present utility model.

[0026] Reference Figures 1-3 As shown, the scraper assembly 100 of the first aspect of the present invention includes: a scraper 20 and a lifting device 1. The lifting device 1 includes: a driving member 11 and a transmission assembly 12. The transmission assembly 12 is located between the driving member 11 and the scraper 20, and the transmission assembly 12 is connected to the driving member 11 and the scraper 20 respectively. The driving member 11 can selectively move in the forward direction and in the reverse direction, so that the scraper 20 can be driven to rise and fall by the transmission assembly 12.

[0027] Specifically, the lifting device 1 mainly consists of a driving component 11 and a transmission assembly 12. Since the transmission assembly 12 is located between the driving component 11 and the scraper 20, it is convenient for the driving component 11 to transmit force to the scraper 20 through the transmission assembly 12. The transmission assembly 12 is connected to both the driving component 11 and the scraper 20, so that the driving component 11 can provide power to the transmission assembly 12, enabling the transmission assembly 12 to drive the scraper 20 to move.

[0028] Furthermore, the driving component 11 can selectively move in the forward and reverse directions. That is, the driving component 11 can move in the forward direction or in the reverse direction. Forward movement means the driving component 11 can rotate in the forward direction (e.g., it can be a motor), or it can move linearly in the forward direction or oscillate in the forward direction. Similarly, reverse movement means the driving component 11 can rotate in the reverse direction, or it can move linearly in the reverse direction or oscillate in the reverse direction. When the driving component 11 moves in the forward direction, it can cause the transmission assembly 12 to drive the scraper blade 20 to move upward. When the driving component 11 moves in the reverse direction, it can cause the transmission assembly 12 to drive the scraper blade 20 to move downward, thereby achieving the raising and lowering of the scraper blade 20 and improving the cleaning effect.

[0029] Furthermore, instead of using multiple cooperating drive components, drive component 11 can be a single drive component, such as a single motor, thereby reducing costs.

[0030] Therefore, the drive component 11 in the scraper assembly 100 can selectively drive the transmission assembly 12 through forward and reverse movements, thereby enabling the scraper 20 to rise and fall, which can reduce costs and improve cleaning effect.

[0031] According to some embodiments of this utility model, such as Figure 4 As shown, the transmission assembly 12 includes: a first transmission mechanism 121 and a second transmission mechanism 122. One end of the first transmission mechanism 121 is connected to the drive member 11, and the first transmission mechanism 121 converts the rotational motion of the drive member 11 into linear motion. The second transmission mechanism 122 is connected to the other end of the first transmission mechanism 121 and the scraper 20, and the second transmission mechanism 122 converts the linear motion of the first transmission mechanism 121 into the lifting and lowering of the scraper 20.

[0032] One end of the first transmission mechanism 121 is connected to the driving member 11, so that the driving member 11 can drive one end of the first transmission mechanism 121 to move. For example, when the driving member 11 is a motor, the driving member 11 rotates. The driving member 11 is connected and cooperates with the reducer. Due to the setting of the first transmission mechanism 121, the first transmission mechanism 121 can convert the rotation of the driving member 11 into linear motion. That is to say, when the driving member 11 rotates, the first transmission mechanism 121 performs linear motion under the drive of the driving member 11.

[0033] Furthermore, when the first transmission mechanism 121 moves linearly, since the second transmission mechanism 122 is connected to the other end of the first transmission mechanism 121, the first transmission mechanism 121 can drive the second transmission mechanism 122 to move. Further, the second transmission mechanism 122 is also connected to the scraper 20, thus the second transmission mechanism 122 can drive the scraper 20 to move. The second transmission mechanism 122 converts the linear motion of the first transmission mechanism 121 into the raising and lowering of the scraper 20. That is, when the first transmission mechanism 121 moves linearly, the second transmission mechanism 122 rotates under the drive of the first transmission mechanism 121. The second transmission mechanism 122 can rise or fall by rotating. Since the scraper 20 is connected to the second transmission mechanism 122, the raising and lowering of the scraper 20 can be achieved.

[0034] According to some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the first transmission mechanism 121 includes a rotating component 1211 and a converting component 1212. The rotating component 1211 is disposed on the driving component 11, and the converting component 1212 is provided with a first sliding groove 12121. The rotating component 1211 is slidably disposed in the first sliding groove 12121. The converting component 1212 is connected to the second transmission mechanism 122 and is adapted to move linearly under the limit of the floor brush housing 9.

[0035] The rotating component 1211 is disposed on the driving component 11, and the driving component 11 can drive the rotating component 1211 to rotate. The conversion component 1212 is provided with a first sliding groove 12121, and the rotating component 1211 can slide within the first sliding groove 12121. When the rotating component 1211 rotates, it can provide a certain force to the first sliding groove 12121. Part of the force will cause the conversion component 1212 containing the first sliding groove 12121 to move linearly along the front-back direction of the scraper assembly 100, and another part of the force will move along the length direction of the first sliding groove 12121, thereby realizing the linear movement of the conversion component 1212.

[0036] Since the conversion component 1212 is connected to the second transmission mechanism 122, for example, the conversion component 1212 can be snapped into the second transmission mechanism 122. When the conversion component 1212 moves in a straight line, the conversion component 1212 can transmit power to the second transmission mechanism 122, thereby driving the second transmission mechanism 122 to move.

[0037] Furthermore, the conversion element 1212 is adapted to move linearly under the constraint of the brush housing 9. In this way, the brush housing 9 can restrict the movement of the conversion element 1212 and provide it with a certain range of motion, thereby making the position of the rotating element more accurate. The brush housing 9 can be correspondingly provided with a groove to restrict the forward and backward linear movement of the conversion element 1212.

[0038] According to some embodiments of this utility model, such as Figure 6 As shown, the rotating component 1211 is one of a crank and an eccentric wheel.

[0039] When the rotating component 1211 is configured as a crank, the linear motion stroke of the conversion component 1212 can be determined by the radius of the crank. When the crank rotates, the circular motion can be decomposed into the forward and backward motion of the scraper assembly 100, or into the left and right motion of the scraper assembly 100, with the forward and backward direction perpendicular to the left and right direction. In this way, the crank can drive the conversion component 1212 to perform reciprocating linear motion.

[0040] Furthermore, when the rotating component 1211 is an eccentric wheel, since the rotation axis of the eccentric wheel does not coincide with its geometric center, the point of contact between the eccentric wheel and the first groove 12121 changes continuously as the eccentric wheel rotates. As the line connecting the rotation axis of the eccentric wheel and the geometric center gradually tilts, the outer edge of the eccentric wheel pushes the conversion component 1212 to reciprocate linearly along the front-back direction of the scraper assembly 100, thereby realizing the linear reciprocating motion of the conversion component 1212.

[0041] According to some embodiments of this utility model, such as Figure 4 As shown, the second transmission mechanism 122 includes: a first transmission member 1221 and a second transmission member 1222. The first transmission member 1221 is disposed on the conversion member 1212 to move linearly synchronously with the conversion member 1212. The second transmission member 1222 is connected to the first transmission member 1221 and the scraper 20 respectively, and the second transmission member 1222 converts the linear movement direction of the first transmission member 1221 into the lifting and lowering of the scraper 20.

[0042] Since the first transmission component 1221 is disposed on the conversion component 1212, for example, the first transmission component 1221 and the conversion component 1212 are snapped together, so the first transmission component 1221 and the conversion component 1212 form a whole. Thus, when the conversion component 1212 moves linearly, since the conversion component 1212 and the first transmission component 1221 form a whole, the first transmission component 1221 can move linearly synchronously with the conversion component 1212.

[0043] Furthermore, the second transmission member 1222 is connected to the first transmission member 1221 and the scraper 20 respectively. When the first transmission member 1221 moves linearly, the first transmission member 1221 can drive the second transmission member 1222 to perform upward and downward movements. Since the second transmission member 1222 is connected to the scraper 20, the upward and downward movements of the scraper 20 can be realized.

[0044] According to some embodiments of this utility model, such as Figure 4 and Figure 11 As shown, the second transmission member 1222 is constructed in an arc shape between the first transmission member 1221 and the scraper 20 to fit the roller brush cover of the floor brush housing 9. One of the first transmission member 1221 and the second transmission member 1222 is provided with a second sliding groove 2, and the other of the first transmission member 1221 and the second transmission member 1222 is provided with a rotating part 3. The rotating part 3 is located in the second sliding groove 2, and the rotating part 3 is in transmission cooperation with the second sliding groove 2.

[0045] The second transmission component 1222 is constructed in an arc shape. The arc-shaped second transmission component 1222 can provide a smoother and more continuous force transmission path. The arc-shaped second transmission component 1222 can reduce stress concentration points and sudden changes in direction during the movement process, making the transmission of power from the first transmission component 1221 to the scraper 20 smoother and reducing energy loss.

[0046] Furthermore, the second transmission component 1222 is constructed in an arc shape, which can form a large-area contact or fit with the inner surface of the roller brush cover, providing a more uniform support force. This can effectively prevent the transmission component from twisting, shaking, or shifting during movement, thereby improving the accuracy and stability of the transmission.

[0047] Furthermore, one of the first transmission member 1221 and the second transmission member 1222 is provided with a second slide groove 2, and the other of the first transmission member 1221 and the second transmission member 1222 is provided with a rotating part 3. That is, when the first transmission member 1221 is provided with the second slide groove 2, the second transmission member 1222 is correspondingly provided with a rotating part 3. When the first transmission member 1221 moves linearly, the rotating part 3 is located in the second slide groove 2, and the second slide groove 2 of the first transmission member 1221 can push the rotating part 3 of the second transmission member 1222 to rotate, thereby realizing the rotation of the second transmission member 1222.

[0048] When the first transmission member 1221 is provided with a rotating part 3, the second transmission member 1222 is provided with a second sliding groove 2 accordingly. When the first transmission member 1221 moves linearly, the rotating part 3 is located in the second sliding groove 2. The rotating part 3 of the first transmission member 1221 can push the second sliding groove 2 of the second transmission member 1222. In this way, the rotating part 3 can rotate relative to the second sliding groove 2, thereby realizing the rotation of the second transmission member 1222.

[0049] According to some embodiments of this utility model, such as Figure 4 and Figure 11 As shown, the first transmission member 1221 moves in the horizontal direction, and the second slide 2 extends at an angle relative to the horizontal and vertical directions.

[0050] In this configuration, when the first transmission member 1221 is provided with a rotating part 3 and the second transmission member 1222 is provided with a second sliding groove 2, the rotating part 3 of the first transmission member 1221 is embedded in the inclined second sliding groove 2. When the first transmission member 1221 moves in the horizontal direction, which is the front-back direction of the scraper assembly 100, the component of the horizontal movement of the rotating part 3 will force the second rotating member to rotate around its rotation center because the second sliding groove 2 extends at an inclination relative to the horizontal and vertical directions. This allows the linear motion of the first transmission member 1221 to be converted into the rotational motion of the second transmission member 1222.

[0051] According to some embodiments of this utility model, such as Figures 2-4 As shown, the transmission assembly 12 further includes an elastic element 4. The first transmission component 1221 is provided with an elastic element mounting portion 41. One end of the elastic element 4 abuts against the elastic element mounting portion 41, and the other end of the elastic element 4 abuts against the floor brush housing 9.

[0052] The first transmission member 1221 has elastic element mounting portions 41 on both sides of its top. These mounting portions 41 not only provide mounting positions for the elastic element 4, facilitating its installation, but also provide support. When an external force drives the first transmission member 1221 to overcome the elastic force of the elastic element 4 and move to a certain position, the potential energy stored in the elastic element 4 is released once the external force disappears. This releases the potential energy, allowing the first transmission member 1221 to automatically return to its initial position, thus enabling the reciprocating linear motion of the first transmission member 1221.

[0053] Specifically, one end of the elastic element 4 abuts against the elastic element mounting portion 41, which provides support to one end of the elastic element 4. The other end of the elastic element 4 abuts against the brush housing 9. The elastic element 4 can be configured as a spring, so that the brush housing 9 can provide support to the other end of the elastic element 4, thereby facilitating deformation of the elastic element 4. When the first transmission member 1221 moves linearly forward of the scraper assembly 100, the elastic element mounting portion 41 can compress and deform the elastic element 4. When the first transmission member 1221 moves linearly backward of the scraper assembly 100, the elastic element 4 restores its elastic deformation, thereby pushing the first transmission member 1221 back to its initial position.

[0054] According to some embodiments of the present invention, it further includes: a control module 5, which is electrically connected to the drive component 11, thereby selectively controlling the drive component 11 to close based on the motion position information of the drive component 11 or the transmission assembly 12.

[0055] Since the control module 5 is electrically connected to the drive component 11, the control module 5 can accurately know the current position of the drive component 11 or the transmission component 12. When it reaches the preset position, the control module 5 immediately issues a command to shut down the drive component 11, thereby preventing the drive component 11 from "overshooting" due to inertia and avoiding impact damage to mechanical structures (such as the floor brush housing 9).

[0056] According to some embodiments of this utility model, such as Figures 6-8 As shown, the transmission assembly 12 includes a rotating member 1211, which is disposed on the driving member 11. The rotating member 1211 is provided with a triggering part 6. The control module 5 includes a first limit switch 51 and a second limit switch 52. The first limit switch 51 is located on one side of the rotating member 1211, and the second limit switch 52 is located on the other side of the rotating member 1211. Both the first limit switch 51 and the second limit switch 52 are electrically connected to the driving member 11. The triggering part 6 selectively triggers the first limit switch 51 and the second limit switch 52.

[0057] The first limit switch 51 and the second limit switch 52 can be configured as Hall effect sensors or micro switches. The first limit switch 51 can detect one extreme position of the rotating part 1211 (when the scraper 20 is in the descending position), and the second limit switch 52 can detect another extreme position (when the scraper 20 is in the ascending position).

[0058] Specifically, when the driving component 11 is a motor, the rotating component 1211 moves forward of the scraper assembly 100 until the trigger part 6 of the rotating component 1211 triggers the first limit switch 51, the motor stops driving, and the scraper 20 descends to the lowest position. When resetting, the motor rotates in the opposite direction, and the rotating component 1211 moves backward of the scraper assembly 100. After the trigger part 6 of the rotating component 1211 triggers the second limit switch 52, it stops moving, and the scraper 20 rises to the highest position. In this way, the raising and lowering of the scraper 20 can be realized.

[0059] According to some embodiments of this utility model, such as Figures 6-8 As shown, the control module 5 also includes a housing 7 and a circuit board 8. The circuit board 8 is disposed inside the housing 7. The first limit switch 51 and the second limit switch 52 are disposed on the circuit board 8, and both the first limit switch 51 and the second limit switch 52 are partially exposed from the housing 7.

[0060] The circuit board 8 is housed within the housing 7, which protects the circuit board 8. The first limit switch 51 and the second limit switch 52 are mounted on the circuit board 8, providing mounting positions for them. Integrating the circuit board 8 with the first limit switch 51 and the second limit switch 52 forms a control module 5, which simplifies internal wiring and eliminates the need for additional connecting wires or plugs to transmit switch signals back to the circuit board 8.

[0061] Furthermore, the first limit switch 51 and the second limit switch 52 are partially exposed in the housing 7, which facilitates the contact connection between the first limit switch 51 and the second limit switch 52 and the trigger part 6 of the rotating member 1211, and facilitates the transmission of signals to the controller, thereby facilitating the controller to control the start and stop of the drive member 11.

[0062] According to some embodiments of this utility model, such as Figure 6 and Figure 7 As shown, the control module 5 is mounted on the surface of the drive component 11. In this way, the drive component 11 can provide a mounting position for the control module 5, which facilitates the installation of the control module 5 and shortens the distance between the drive component 11 and the control module 5, thereby making the signal transmission between the drive component 11 and the control module 5 more accurate.

[0063] like Figure 1 and Figure 2 As shown, the floor brush 200 according to the second aspect of the present invention includes: a floor brush housing 9, a scraper assembly 100 and a window assembly 10 as described above, a drive member 11 is disposed on the floor brush housing 9, a transmission assembly 12 is movably disposed on the floor brush housing 9, and the window assembly 10 is detachably disposed on the floor brush housing 9, and the window assembly 10 at least partially covers the scraper assembly 100.

[0064] The drive component 11 is disposed on the brush housing 9, which provides an installation position and housing space for the drive component 11, thereby facilitating its installation. The transmission assembly 12 is movably disposed on the brush housing 9, thus facilitating the drive component 11 to raise and lower the scraper blade 20 via the transmission assembly 12.

[0065] Furthermore, the viewing window assembly 10 is detachably mounted on the brush housing 9. The viewing window assembly 10 allows a clear view of the internal structure of the brush housing 9, facilitating observation of the operation of the brush 200. When the entire viewing window assembly 10 is detached from the brush housing 9, the conversion component 1212 separates from the rotating component 1211. The rotating component 1211 automatically resets to the position of the second limit switch 52 under the drive of the drive component 11. The second limit switch 52 is located behind the rotating component 1211, i.e., at its rearmost position. Simultaneously, the first transmission component 1221 resets to its rearmost position under the action of the elastic component 4, thus facilitating the docking of the conversion component and the rotating component 1211 when the viewing window assembly 10 is reinstalled.

[0066] The cleaning device 300 according to a third aspect of the present invention includes: the floor brush 200 described above.
