[0052] refer to Figure 1The following describes a cleaning brush head for a cleaning device provided by an embodiment of this application. The brush head includes: a base 1 with a suction port configured to suck up dirt from the surface to be cleaned; a roller brush 2 rotatably connected to the base 1; and a scraper assembly 3 including a first scraper assembly 31 and a second scraper assembly 32, which are respectively disposed on both sides of the roller brush 2 and are both connected to the base 1. When the cleaning brush head moves in a first direction, the first scraper assembly 31 moves to a first position and the second scraper assembly 32 moves to a second position. When the cleaning brush head moves in a second direction, the first scraper assembly 31 moves to a third position and the second scraper assembly 32 moves to a fourth position.

[0053] In one embodiment of this application, the suction port is disposed between the first scraper assembly 31 and the second scraper assembly 32.

[0054] In a specific embodiment of this application, the movement of the first scraper assembly 31 includes at least the first position and the third position described above; the movement of the second scraper assembly 32 includes at least the second position and the fourth position described above.

[0055] In one embodiment of this application, the first direction can be the forward direction of the cleaning device, and the second direction can be the backward direction of the cleaning device; the first direction can also be the front right direction of the cleaning device, that is, the cleaning device tilts to the right, for example, turning right; the second direction can also be the front left direction of the cleaning device, that is, the cleaning device tilts to the left, for example, turning left.

[0056] In one embodiment of this application, the first scraper assembly 31 moving to a first position indicates that the first scraper assembly 31 is separated from the cleaning surface; the second scraper assembly 32 moving to a second position indicates that the second scraper assembly 32 is in contact with the cleaning surface; the first scraper assembly 31 moving to a third position indicates that the first scraper assembly 31 is in contact with the cleaning surface; and the second scraper assembly 32 moving to a fourth position indicates that the second scraper assembly 32 is separated from the cleaning surface. In other words, in the first direction, the first scraper assembly 31 is not working, and the second scraper assembly 32 is working; in the second direction, the first scraper assembly 31 is working, and the second scraper assembly 32 is not working.

[0057] In one embodiment of this application, the first position is the position where the working end of the scraper in the first scraper assembly 31 is spaced apart from the cleaning surface by a first preset distance; the third position is the position where the working end of the scraper in the first scraper assembly 31 is spaced apart from the cleaning surface by a second preset distance; the second preset distance is less than the first preset distance; the second position is the position where the working end of the scraper in the second scraper assembly 32 is spaced apart from the cleaning surface by a third preset distance; the fourth position is the position where the working end of the scraper in the second scraper assembly 32 is spaced apart from the cleaning surface by a fourth preset distance; the fourth preset distance is greater than the third preset distance.

[0058] In one embodiment of this application, the first preset distance is 8-10 cm, the second preset distance is 0-2 cm, the third preset distance is 0-2 cm, and the fourth preset distance is 8-10 cm.

[0059] In one embodiment of this application, the first and third positions may also be the positions in which the scraper assembly 3 is housed inside the cleaning brush head housing to detach from the cleaning surface, and the second and fourth positions may also be the positions in which the scraper assembly 3 extends outside the cleaning brush head housing to press against or contact the cleaning surface.

[0060] In one embodiment of this application, the first direction is the forward direction of the cleaning device, and the second direction is the backward direction of the cleaning device. In this case, the first scraper assembly 31 is the front scraper assembly 31, and the second scraper assembly 32 is the rear scraper assembly 32. During the forward movement of the cleaning device, the front scraper assembly 31 moves to the first position to be stored and disengage from the cleaning surface, and the rear scraper assembly 32 moves to the second position to rise and contact the cleaning surface. Thus, during the forward movement of the cleaning device, the rear scraper assembly 32 pushes water stains forward to the roller brush 2 and the suction port. During the backward movement of the cleaning device, the front scraper assembly 31 moves to the third position to rise and contact the cleaning surface, and the rear scraper assembly 32 moves to the fourth position to disengage from the cleaning surface. Thus, during the backward movement of the cleaning device, the front scraper pushes water stains backward to the roller brush 2 and the suction port.

[0061] refer to Figure 1 A schematic diagram showing the positions of the first scraper assembly 31 and the second scraper assembly 32 as the cleaning equipment moves in the forward direction.

[0062] refer to Figure 2 A schematic diagram showing the positions of the first scraper assembly 31 and the second scraper assembly 32 during the backward movement of the cleaning equipment.

[0063] In one embodiment of this application, the cleaning brush head may include a first driving device and a second driving device. The first driving device includes a first driving member 411 and a first transmission shaft 421. The first driving member 411 is communicatively connected to a control device and is configured to operate in response to a control signal from the control device. When the first driving member 411 is operating, the first transmission shaft 421 rotates. Specifically, refer to... Figure 3The non-contact end of the front wiper assembly 31 is sleeved on the first drive shaft 421 so that the front wiper assembly 31 switches between a first position and a third position when the first drive member 411 is running; the second drive device includes a second drive member 412 and a second drive shaft 422, the second drive member 412 is communicatively connected to the controller, and the second drive member 412 is configured to operate in response to the control signal of the control device; when the second drive member 412 is running, the second drive shaft 422 rotates; specifically, refer to Figure 4 A connecting plate is provided at the non-contact end of the rear scraper assembly 32. The connecting plate is sleeved on the second drive shaft 422 so that the rear scraper assembly 32 can switch between the second position and the fourth position when the second drive member 412 is running.

[0064] In one embodiment of this application, the driving component 41 can be directly driven to the transmission shaft, or it can be driven through a transmission component. Specifically, the transmission component can be a transmission structure such as a gear or a cam.

[0065] In one embodiment of this application, the cleaning brush head may include a third driving device, wherein the third driving device includes a third driving member 413, a third transmission shaft 423, and a linkage rod 43. The third driving member 413 is communicatively connected to a control device and is configured to operate in response to a control signal from the control device. When the third driving member 413 is operating, the third transmission shaft 423 rotates. Specifically, refer to... Figure 5 A connecting plate is provided on the non-contact end of the rear scraper assembly and sleeved on the third drive shaft 423. At the same time, the third drive shaft 423 is connected to the non-contact end of the front scraper assembly 31 through the linkage rod 43. The front scraper assembly 31 is connected to the cleaning brush head housing through the fourth drive shaft 424, so that when the third drive component 413 is running, the rear scraper assembly 32 and the front scraper assembly 31 switch synchronously. For example, when the front scraper assembly 31 is in the first position, the rear scraper assembly 32 is in the second position; when the front scraper assembly 31 is in the third position, the rear scraper assembly 32 is in the fourth position.

[0066] In one embodiment of this application, the first direction can be the right-turning direction of the cleaning device, which includes a right forward direction and a left backward direction. The second direction is the left-turning direction of the cleaning device, which includes a left forward direction and a right backward direction. In this case, the first scraper assembly 31 can be the left scraper assembly 31, and the second scraper assembly 32 can be the right scraper assembly 32. During the movement of the cleaning device in the right-turning direction, the left scraper assembly 31 moves to the first position to disengage from the cleaning surface, and the right scraper assembly 32 moves to the second position and rises to contact the cleaning surface. Thus, during the right-turning process of the cleaning device, the right scraper assembly 32 pushes water stains to the right onto the roller brush 2 and the suction port. During the movement of the cleaning device in the left-turning direction, the left scraper assembly 31 moves to the third position to contact the cleaning surface, and the right scraper assembly 32 moves to the fourth position and rises to disengage from the cleaning surface. Thus, during the left-turning process of the cleaning device, the left scraper assembly 31 pushes water stains to the left onto the roller brush 2 and the suction port.

[0067] In one embodiment of this application, the cleaning brush head of the cleaning device has a first scraper assembly 31 and a second scraper assembly 32 arranged on both sides of the roller brush 2. The movement direction of the first scraper assembly 31 and the second scraper assembly 32 changes with the movement direction of the cleaning brush head. Specifically, the first scraper assembly 31 moves to a first position, indicating that the first scraper assembly 31 is separated from the cleaning surface; the second scraper assembly 32 moves to a second position, indicating that the second scraper assembly 32 is in contact with the cleaning surface; the first scraper assembly 31 moves to a third position, indicating that the second scraper assembly 32 is in contact with the cleaning surface; and the second scraper assembly 32 moves to a fourth position, indicating that the second scraper assembly 32 is separated from the cleaning surface. In other words, in the first direction, the first scraper assembly 31 is not working, and the second scraper assembly 32 is working; in the second direction, the first scraper assembly 31 is working, and the second scraper assembly 32 is not working. By changing the working state of the first scraper assembly 31 and the second scraper assembly 32, the cleaning needs of the cleaning device in different directions are met, thereby reducing water stain residue and improving the user's comfort in using the cleaning device.

[0068] In one embodiment of this application, the cleaning brush head of the cleaning device further includes a sensing component disposed on the cleaning brush head, the sensing component being configured to acquire motion information of the cleaning brush head.

[0069] In one embodiment of this application, the motion information of the cleaning brush head includes information such as the direction of motion and the speed of motion.

[0070] In one embodiment of this application, the moving positions of the first scraper assembly 31 and the second scraper assembly 32 are determined based on the direction of movement; and the position switching speed of the first scraper assembly 31 and the second scraper assembly 32 is determined based on the movement speed.

[0071] refer to Figure 6 In one embodiment of this application, the sensing component includes a movable roller 51, which is disposed at the bottom of the cleaning brush head, and at least part of the cleaning brush head is exposed and in contact with the cleaning surface on the side that is close to the cleaning surface. The movable roller 51 is configured to drive the cleaning brush head to move.

[0072] In one embodiment of this application, the sensing component further includes a transmission wheel assembly. At least a portion of the transmission wheel assembly is connected to and rotates synchronously with the movable roller 51. Specifically, the movable roller 51 is connected to the transmission wheel assembly via a first transmission rod 52. The transmission wheel assembly includes a first transmission wheel 53 and a second transmission wheel 54. The first transmission wheel 53 is fixedly connected to the movable roller 51 via the first transmission rod 52 and rotates synchronously. The second transmission wheel 54 meshes with the first transmission wheel 53 and is configured to rotate under the drive of the first transmission wheel 53; that is, the second transmission wheel 54 is the driven wheel of the first transmission wheel 53.

[0073] In one embodiment of this application, the number of teeth on the first transmission wheel 53 is greater than the number of teeth on the second transmission wheel 54. In response to the movable roller 51 driving the first transmission wheel 53 to rotate, the second transmission wheel 54 rotates along with the first transmission wheel 53. Since the number of teeth on the first transmission wheel 53 is greater than the number of teeth on the second transmission wheel 54, when the first transmission wheel 53 drives the second transmission wheel 54 to rotate, the rotational speed angle of the second transmission wheel 54 is greater than the rotational angle of the first transmission wheel 53. Therefore, the rotation of the first transmission wheel 53 can be amplified by the second transmission wheel 54, thereby improving the sensing accuracy of minute rotations or rotational trends of the cleaning brush head.

[0074] In one embodiment of this application, the tooth ratio of the first transmission wheel 53 to the second transmission wheel 54 is 30-80; thereby, the minute rotation of the first transmission wheel 53 can be amplified, thereby improving the sensing accuracy of the minute rotation or rotation trend of the cleaning brush head; preferably, the tooth ratio of the first transmission wheel 53 to the second transmission wheel 54 can be 50, in which case the gear differential ratio of the first transmission wheel 53 to the second transmission wheel 54 is 50, thereby enabling the second transmission wheel 54 to amplify the minute rotation of the first transmission wheel 53.

[0075] In one embodiment of this application, the sensing component further includes a sensing element 55, which is disposed near the second transmission wheel 54. The sensing element 55 is configured to sense the movement and direction of the transmission wheel assembly and output movement information.

[0076] In one embodiment of this application, in response to the rotation of the movable roller 51 relative to the cleaning surface, the first transmission wheel 53 rotates synchronously with the movable roller 51. Since the first transmission wheel 53 meshes with the second transmission wheel 54, the second transmission wheel 54 rotates in either the forward or reverse direction under the transmission of the first transmission wheel 53. The rotation is in response to the cleaning brush head having at least a tendency to move in a first direction. The second transmission wheel 54 rotates in the forward direction, and the sensing element 55 outputs motion information characterizing the movement of the cleaning brush head in the first direction. The rotation is in response to the cleaning brush head having at least a tendency to move in a second direction. The second transmission wheel 54 rotates in the reverse direction, and the sensing element 55 outputs motion information characterizing the movement of the cleaning brush head in the second direction.

[0077] In one embodiment of this application, forward rotation can be clockwise rotation, and reverse rotation can be counterclockwise rotation.

[0078] In one embodiment of this application, the sensing component further includes a second transmission rod 56 and a third transmission wheel 57, wherein the second transmission rod 56 is connected to the second transmission wheel; the second transmission wheel and the third transmission wheel 57 are coaxially arranged on the second transmission rod 56, and the third transmission wheel 57 is configured to make the rotation angle of the second transmission wheel easier to be identified by the sensing element 55.

[0079] In one embodiment of this application, the sensing component includes at least one of the following: a stress sensor, a TOF component, a line laser component, a radar component, an IMU, an encoder, and a Hall sensor.

[0080] In one embodiment of this application, the sensing element 55 is a Hall encoder, and the speed is measured by detecting the pulse signal output by the Hall encoder; specifically, the movement of the cleaning brush head toward the first direction or the second direction is determined by detecting the rising edge pulse and the falling edge pulse.

[0081] In one embodiment of this application, a stress sensor may be provided at the front end of the roller brush. The stress sensor is used to determine whether the cleaning brush head collides with an obstacle, thereby detecting the space at the front end of the cleaning brush head to determine corner cleaning. Other components in the sensing assembly can also be used for determination, which will not be elaborated upon here.

[0082] In one embodiment of this application, the cleaning brush head further includes a control component connected to the base 1, the control component being configured to control the movement of the scraper assembly 3.

[0083] In one embodiment of this application, the sensing component transmits the motion information of the cleaning brush head to the control component, and the control component controls the movement of the scraper assembly 3 based on the motion information; specifically, the control component determines the moving position of the scraper assembly 3 based on the direction of motion, and determines the moving speed of the scraper assembly 3 based on the speed of motion.

[0084] In one embodiment of this application, the control component includes: a control device, which is communicatively connected to the sensing element 55; and a drive device, which is communicatively connected to the control device and drively connected to the scraper assembly 3.

[0090] In one embodiment of this application, the drive component 41 is the power source of the scraper assembly 3. Specifically, the drive component 41 can be a drive motor or a drive servo motor.

[0091] In one embodiment of this application, when the drive shaft 42 rotates, the drive shaft 42 drives the scraper assembly 3 to rotate, thereby causing the first scraper assembly 31 to switch between a first position and a third position, and causing the second scraper assembly 32 to switch between a second position and a fourth position.

The control signal may be an electronic signal sent by a controller or a pressing action given by a mechanical structure. When the first driving member 411 is running, the first transmission shaft 421 rotates. Specifically, the non-contact end of the first scraper assembly 31 is sleeved on the first transmission shaft 421 so that when the first driving member 411 is running, the first scraper assembly 31 rotates accordingly. The first drive shaft 421 rotates, thereby switching between a first position and a third position; the second drive device includes a second drive member 412 and a second drive shaft 422, the second drive member 412 is communicatively connected to the controller, and the second drive member 412 is configured to operate in response to the control signal of the control device; when the second drive member 412 is running, the second drive shaft 422 rotates; specifically, a connecting plate is provided at the non-contact end of the second scraper assembly 32, and the connecting plate is sleeved on the second drive shaft 422 so that when the second drive member 412 is running, the second scraper assembly 32 rotates with the rotation of the second drive shaft 422, thereby switching between a second position and a fourth position.

[0100] In one embodiment of this application, the driving component 41 can be directly driven to the transmission shaft, or it can be driven through a transmission component. Specifically, the transmission component can be a transmission structure such as a gear or a cam.

[0101] In one embodiment of this application, the cleaning brush head may include a drive device and a linkage rod 43. The drive shaft 42 of the drive device is connected to any scraper assembly 3, and the drive shaft 42 is connected to another scraper assembly 3 via the linkage rod 43.

[0102] In one embodiment of this application, the cleaning brush head is provided with a driving device, which simultaneously drives the positional changes of the first scraper assembly 31 and the second scraper assembly 32, thereby reducing the space occupied by the driving device and improving the regularity of the internal structure of the cleaning equipment.

[0103] In one embodiment of this application, when the cleaning brush head uses a drive device, the drive device is a rotary drive device including a drive shaft 42.

[0104] refer to Figure 5 In one embodiment of this application, the driving assembly may include a third driving device, wherein the third driving device includes a third driving member 413, a third transmission shaft 423, and a linkage rod 43. The third driving member 413 is communicatively connected to the control device and is configured to operate in response to the control signal of the control device. When the third driving member 413 is operating, the third transmission shaft 423 rotates. Specifically, a connecting plate is provided on the non-contact end of the second scraper assembly 32 and sleeved on the third transmission shaft 423. At the same time, the third transmission shaft 423 is connected to the first scraper through the linkage rod 43. The non-contact end of component 31 is connected. The first scraper assembly 31 is connected to the cleaning brush head housing via the fourth drive shaft 424. When the third drive member 413 is running, the third drive shaft 423 drives the second scraper assembly 32 to rotate, and the fourth drive shaft 424 drives the first scraper assembly 31 to rotate. Thus, the second scraper assembly 32 and the first scraper assembly 31 switch synchronously. Preferably, when the first scraper assembly 31 is in the first position, the second scraper assembly 32 is in the second position; when the first scraper assembly 31 is in the third position, the second scraper assembly 32 is in the fourth position.

[0105] In one embodiment of this application, the first scraper assembly 31 includes an arc-shaped scraper portion 311, which is bent toward the position of the roller brush 2; the second scraper assembly 32 includes a flat scraper portion 321, which is perpendicular to the cleaning surface.

[0106] In one embodiment of this application, by setting the scraper portion of the first scraper assembly 31 as an arc-shaped scraper portion 311 and the scraper portion of the second scraper assembly 32 as a flat scraper portion 321, the adaptability of different scraper portions to different application scenarios is ensured. For example, if the cleaning equipment is a floor scrubber, the backward pulling force is greater than the forward pushing force during the cleaning process. The first scraper assembly 31 can be the front scraper assembly 31, and the second scraper assembly 32 can be the rear scraper assembly 32. When the first scraper assembly 31 is working, the curved first scraper assembly 31 can avoid generating large friction with the ground to reduce the backward pulling force, while also pushing water stains towards the roller brush 2. When the second scraper assembly 32 is working, the vertical second scraper assembly 32 can push more water stains towards the roller brush 2, thereby improving the matching between the cleaning equipment and the application scenario.

[0107] In one embodiment of this application, the first scraper assembly 31 further includes a first fixing part 312, and the second scraper assembly 32 further includes a second fixing part 322. The first scraper assembly 31 connects the arc-shaped scraper part 311 to the driving device through the first fixing part 312, and the second scraper assembly 32 connects the flat scraper part 321 to the driving device through the second fixing part 322.

[0108] In one embodiment of this application, a first fixing part 321 is disposed at the non-contact end of the first scraper assembly 31; a second fixing part 322 is disposed at the non-contact end of the second scraper assembly 32.

[0109] In one embodiment of this application, the first fixing part 312 is sleeved on the transmission shaft 42, and the second fixing part 322 is sleeved on the transmission shaft 42.

[0110] In one embodiment of this application, the base 1 is provided with a first through hole and a second through hole, and the second fixing part 322 is provided with a third through hole. The drive shaft 42 passes through the first through hole, the third through hole and the second through hole in sequence, so that the drive device is connected to the base.

[0111] In one embodiment of this application, both the first fixing part 312 and the second fixing part 322 are provided with sliders.

[0112] The cleaning brush head in one embodiment of this application has the following beneficial effects:

[0113] The cleaning brush head provided in this application has a first scraper assembly 31 and a second scraper assembly 32 arranged on both sides of the roller brush 2. The movement direction of the first scraper assembly 31 and the second scraper assembly 32 changes with the movement direction of the cleaning brush head. Specifically, the first scraper assembly 31 moves to a first position, indicating that the first scraper assembly 31 is separated from the cleaning surface; the second scraper assembly 32 moves to a second position, indicating that the second scraper assembly 32 is in contact with the cleaning surface; the first scraper assembly 31 moves to a third position, indicating that the second scraper assembly 32 is in contact with the cleaning surface; and the second scraper assembly 32 moves to a fourth position, indicating that the second scraper assembly 32 is separated from the cleaning surface. In other words, in the first direction, the first scraper assembly 31 is not working, and the second scraper assembly 32 is working; in the second direction, the first scraper assembly 31 is working, and the second scraper assembly 32 is not working. By changing the working state of the first scraper assembly 31 and the second scraper assembly 32, the needs of the cleaning equipment for cleaning water stains in different directions can be met, thereby reducing water stain residue and improving the user's comfort in using the cleaning equipment.
