Description

Technical Field

DETAILED DESCRIPTION

[0067] To make the objectives, technical solutions, and advantages of the present disclosure more clear, the present disclosure will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only a portion of the embodiments of the present disclosure, rather than all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative effort are intended to fall within the scope of protection of the present disclosure.

[0068] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the present disclosure. The singular forms "a," "the," and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. "A variety of" generally includes at least two, and other quantifiers are similar.

[0069] It should be understood that although the terms "first," "second," "third," etc. may be used to describe in the present disclosure, these descriptions should not be limited to these terms. These terms are only used to distinguish the objects being described. For example, without departing from the scope of the present disclosure, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. In addition, the terms "first," "second," "third," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0070] In the description of this disclosure, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0071] It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or device. In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or device comprising the element.

[0072] When cleaning equipment is performing cleaning tasks, it is difficult to fully clean certain areas, such as corners or under the base of walls. When the roller brush reaches the base of the wall, the cylindrical roller brush contacts the wall surface and misses the dead corners under the base of the wall that cannot be reached, resulting in incomplete cleaning and affecting the cleaning effect.

[0073] Therefore, an embodiment of the present disclosure provides a cleaning brush head, comprising: an induction wheel assembly, arranged on the cleaning brush head, the induction wheel assembly being configured to obtain movement information of the cleaning brush head; a floating assembly, configured to perform a floating action according to the movement information, the floating assembly comprising a scraping bar assembly, when the cleaning brush head moves along a first direction, the scraping bar assembly moves to a first position in a linear motion; when the cleaning brush head moves along a second direction, the scraping bar assembly moves to a second position in a linear motion.

[0074] The cleaning brush head provided by the present disclosure uses a sensor wheel assembly to sense the movement of the cleaning brush head. The floating assembly then performs a floating action based on the motion information. When the cleaning brush head moves in a first direction, the scraping bar assembly moves to a first position to clean narrow spaces such as corners. When the cleaning brush head moves in a second direction, the scraping bar assembly moves to a second, retracted position. Therefore, the present disclosure can automatically control the scraping bar assembly to perform a scraping action through the sensor wheel assembly, thereby automatically cleaning narrow spaces such as corners.

[0075] Optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0076] To more clearly describe the behavior of cleaning the brush head, such as Figure 1As shown, the following directions are defined: the cleaning brush head can be calibrated along three mutually perpendicular axes: the transverse axis Y, the front-to-back axis X, and the central vertical axis Z. The direction of the arrow along the front-to-back axis X is designated as "rearward," and the direction opposite the arrow along the front-to-back axis X is designated as "forward." The direction of the arrow along the transverse axis Y represents the "right side" of the cleaning brush head, while the direction opposite the arrow along the transverse axis Y represents the "left side" of the cleaning brush head. The vertical axis Z extends upward along the bottom surface of the cleaning brush head. The direction of the arrow along the vertical axis Z represents the "upper side" of the cleaning brush head, while the direction opposite the arrow along the vertical axis Z represents the "lower side" of the cleaning brush head.

[0077] like Figure 1 As shown, an embodiment of the present application provides a cleaning brush head 100, which is applied to cleaning equipment such as floor scrubbers. The cleaning brush head includes: a sensing wheel assembly, which is configured to sense motion information of the cleaning brush head, wherein the motion information includes at least the motion state and one of the motion directions of the cleaning brush head; the motion direction includes a first direction and a second direction, wherein the first direction is movement from front to back, and the second direction is movement from back to front.

[0078] Figure 1 This is a schematic diagram of the structure of the floating component 120 in the cleaning brush head rising up. Figure 2 This is a schematic diagram of the structure of the floating component 120 falling in the cleaning brush head. Figure 1-Figure 2 As shown, the cleaning brush head 100 further includes a floating component 120, which performs a floating action according to the motion information. The floating component 120 includes a scraper component 121. When the cleaning brush head moves in a first direction, the scraper component 121 moves to a first position. For example, when the cleaning brush head reaches a corner position and is about to move in the first direction, the scraper component 121 moves to the first position. Figure 2 When the cleaning brush head 100 moves in the second direction, the scraper assembly 121 moves to the second position, as shown Figure 1 When the roller brush 110 of the cleaning brush head 100 reaches the corner, the roller brush 110 is a cylindrical structure and cannot reach the corner. At this time, the scraper assembly 121 automatically moves from the second position of the storage state (such as Figure 1 ) to a first position (as shown) where a scraping action can be performed Figure 2 As shown), at this time, as the cleaning brush head 100 moves along the first direction, the scraper assembly 121 can clean the corners of the wall.

[0079] In some embodiments, when the cleaning brush head is cleaning a non-corner cleaning surface, or when the cleaning brush head is detected to be moving in a first direction, the scraper assembly 121 may also move to the first position, such as Figure 2As shown, the clean surface is scraped to enhance the decontamination effect.

[0080] In some embodiments, when the cleaning brush head 100 moves along the second direction, the scraper assembly 121 moves to the second position, such as Figure 1 As shown, damage to the wiper strip assembly 121 due to reverse movement is avoided.

[0081] In some embodiments, the cleaning brush head 100 further includes an induction wheel assembly 130, such as Figure 3 As shown, the sensor wheel assembly 130 is disposed inside the cleaning brush head 100 and at least partially exposed from the cleaning brush head 100 to contact the cleaning surface. The sensor wheel assembly 130 is configured to obtain motion information of the cleaning brush head 100 .

[0082] In some embodiments, the induction wheel assembly 130 includes: a first roller 134, which is arranged at the bottom of the cleaning brush head 100, and at least partially exposed on the side of the cleaning brush head 100 that is adjacent to the cleaning surface and contacts the cleaning surface, and is configured to drive the cleaning brush head 100 to move.

[0083] In some embodiments, the sensing wheel assembly 130 further includes a transmission wheel assembly, at least a portion of which is connected to the first roller 134 and rotates synchronously. Specifically, the first roller 134 and the transmission wheel assembly are connected via a first transmission rod 1311. The transmission wheel assembly includes a first transmission wheel 131 and a second transmission wheel 132. The first transmission wheel 131 and the first roller 134 are fixedly connected via the first transmission rod 1311 and rotate synchronously. The second transmission wheel 132 is engaged with the first transmission wheel 131 and is configured to rotate under the drive of the first transmission wheel 131. That is, the second transmission wheel 132 is a driven wheel of the first transmission wheel 131.

[0084] In some embodiments, as Figure 4As shown, the first transmission wheel 131 has a greater number of teeth than the second transmission wheel 132. In response to the first roller 134 driving the first transmission wheel 131 to rotate, the second transmission wheel 132 rotates along with the rotation of the first transmission wheel 131. Because the first transmission wheel 131 has a greater number of teeth than the second transmission wheel 132, when the first transmission wheel 131 drives the second transmission wheel 132 to rotate, the second transmission wheel 132 rotates at a faster speed than the first transmission wheel 131. In other words, the second transmission wheel 132 rotates at a faster angular velocity than the first transmission wheel 131. Within a unit of time, the second transmission wheel 132 rotates at a greater angle than the first transmission wheel 131. Consequently, the second transmission wheel 132 amplifies even small rotations of the first transmission wheel 131, making even small rotations or rotational trends of the cleaning brush head 100 more easily detected by the sensing element 135 of the sensing wheel assembly 130.

[0085] In some embodiments, the gear ratio between the first transmission wheel 131 and the second transmission wheel 132 is 30 to 80. This amplifies even small rotations of the first transmission wheel 131, making the rotation angle of the second transmission wheel 132 easily detectable by the sensing element 135 of the sensing wheel. Preferably, the gear ratio between the first transmission wheel 131 and the second transmission wheel 132 is 50. In this case, the differential gear ratio between the first transmission wheel 131 and the second transmission wheel 132 is 50, allowing the second transmission wheel 132 to significantly amplify even small rotations of the first transmission wheel 131.

[0086] In some embodiments, the sensing wheel assembly 130 further includes a sensing element 135. The sensing element 135 is positioned adjacent to the second transmission wheel 132 and is configured to sense the movement and direction of the transmission wheel assembly and output a signal to the floating assembly. Specifically, the sensing element 135 can monitor the movement state and direction of the second transmission wheel 132 and output a signal to the floating assembly based on the movement information of the second transmission wheel 132.

[0087] In some embodiments, in response to the first roller 134 rotating relative to the cleaning surface, the first transmission wheel 131 rotates synchronously with the first roller 134. Due to the meshing of the first transmission wheel 131 and the second transmission wheel 132, the second transmission wheel 132 rotates forward or reversely under the drive of the first transmission wheel 131. In response to the cleaning brush head 100 exhibiting at least a tendency to move in the first direction, the second transmission wheel 132 rotates forward, and the sensing element 135 outputs a first signal. In response to the cleaning brush head 100 exhibiting at least a tendency to move in the second direction, the second transmission wheel 132 rotates reversely, and the sensing element 135 outputs a second signal. The first and second signals have different waveforms, and the first and second signals can be used to control the floating assembly to switch between the first and second positions.

[0088] It should be noted that the cleaning brush head 100 has at least a tendency to move in the first direction or the second direction, which can be understood as the first roller 134 having a tendency to rotate forward or reverse, or the first roller 134 has already rotated forward or reverse. The forward rotation can be clockwise, and the reverse rotation can be counterclockwise.

[0089] In some embodiments, the sensing element 135 may be a Hall effect encoder, and the speed is measured by detecting the pulse signal output by the Hall effect encoder. By detecting the rising edge pulse and the falling edge pulse, it is determined whether the cleaning brush head 100 is moving in the first direction or the second direction. In response to the cleaning brush head 100 moving in the first direction, the scraper assembly 121 switches to the first position to perform a scraping action; in response to the cleaning brush head 100 moving in the second direction, the scraper assembly 121 switches to the second position and remains in the stored state.

[0090] In some embodiments, the motion information of the cleaning brush head 100 can also be determined by at least one of the following sensing elements 135: a stress sensor, a TOF component, a line laser component, a radar component, an IMU, and an encoder. For example, the stress sensor at the front end of the roller brush 110 can be used to determine whether the cleaning brush head 100 has collided with an obstacle, such as a wall, so as to detect that the front end of the cleaning brush head 100 has reached the edge of the obstacle. At this time, it can be determined that the corner between the obstacle and the surface to be cleaned can no longer be cleaned by the roller brush 110. The radar component can also be used to determine whether the cleaning brush head 100 has reached the edge of the wall corner. It can also be determined by other sensing wheel components 130, which will not be described in detail.

[0091] In some embodiments, the sensing wheel assembly 130 further includes a drive box, which is provided with a second transmission rod 1321, which is connected to the second transmission wheel 132. A third transmission wheel 133 is provided on the second transmission rod 1321, between the second transmission wheel 132 and the drive box. The third transmission wheel 133 rotates synchronously with the second transmission wheel 132, and is configured to make the rotation angle of the second transmission wheel 132 more easily recognized by the sensing element 135.

[0092] Specifically, since the number of teeth of the second transmission wheel 132 is smaller than the number of teeth of the first transmission wheel 131, and the second transmission wheel 132 is smaller as a whole, during the rotation process, the rotation angle of the second transmission wheel 132 is not easily recognized by the sensing element 135. Therefore, a third transmission wheel 133 is provided on the second transmission rod 1321. The third transmission wheel 133 is coaxially arranged with the second transmission wheel 132 and is configured to amplify the rotation angle of the second transmission wheel 132. At this time, the sensing element 135 can more easily identify the rotation angle of the third transmission wheel 133, and then quickly feed back the movement information of the cleaning brush head 100 to the drive assembly 122.

[0093] In some embodiments, the induction wheel assembly 130 further includes a shock-absorbing spring 136, which is disposed between the first roller 134 and the housing of the cleaning brush head 100 and is configured to absorb shock for the induction wheel assembly 130 when the brush head falls from a plane with a drop, thereby preventing the induction wheel assembly 130 from being damaged.

[0094] In other embodiments, the cleaning brush head 100 further includes a second roller, which is assembled with the bottom of the cleaning brush head 100. In response to the rotation of the first roller 134, the second roller assists the movement of the cleaning brush head 100, and the second roller is connected to the transmission wheel group, and at least a portion of the transmission wheel group rotates synchronously with the second roller. Specifically, the second roller is connected to the transmission wheel group through a first transmission rod 1311. The transmission wheel group includes a first transmission wheel 131 and a second transmission wheel 132, and the first transmission wheel 131 and the first roller 134 are fixedly connected and rotate synchronously through the first transmission rod 1311. The second transmission wheel 132 is engaged with the first transmission wheel 131 and is configured to rotate under the drive of the first transmission wheel 131, that is, the second transmission wheel 132 is the driven wheel of the first transmission wheel 131. Because the first transmission wheel 131 has a greater number of teeth than the second transmission wheel 132, when the first transmission wheel 131 drives the second transmission wheel 132 to rotate, the second transmission wheel 132 rotates at a faster speed than the first transmission wheel 131. Specifically, the second transmission wheel 132 rotates at a faster angular velocity than the first transmission wheel 131. Within a unit of time, the second transmission wheel 132 rotates at a greater angle than the first transmission wheel 131. Consequently, the second transmission wheel 132 amplifies even small rotations of the first transmission wheel 131, making even small rotations or rotational trends of the cleaning brush head 100 more easily detected by the sensing element 135 of the sensing wheel assembly 130. In this embodiment, the sensing wheel assembly 130 can be independently implemented as a set of wheels on the cleaning brush head 100. In response to movement of the cleaning brush head, the sensing wheel assembly detects the movement of the cleaning brush head through the movement of the second roller.

[0095] In some embodiments, as Figure 5 As shown, Figure 5: is a schematic structural diagram of a floating assembly according to an exemplary embodiment. The floating assembly 120 includes a floating assembly housing 123, which is arranged at the front end of the cleaning brush head 100. The floating assembly housing 123 can accommodate a roller brush 110, etc. The floating assembly 120 also includes a driving assembly 122, which is located in the floating assembly housing 123. The driving assembly 122 is configured to drive the scraper assembly 121 to switch between the first position and the second position according to the sensing result of the sensing wheel assembly 130. Specifically, the driving assembly 122 is configured to receive the first signal or the second signal. In response to the driving assembly 122 receiving the first signal, the scraper assembly 121 moves to the first position; in response to the driving assembly 122 receiving the second signal, the scraper assembly 121 moves to the second position. The switching of the scraper assembly 121 between the first position and the second position includes the scraper assembly 121 moving up and down in the vertical direction and rotating. Compared with the rotational movement, the scraper body 1212 in the scraper assembly 121 can better fit the corner position of the obstacle when moving up and down in the vertical direction, thereby avoiding the scraper body 1212 from touching the obstacle during the rotational movement and damaging the scraper assembly 121.

[0096] In some embodiments, as Figure 5 As shown, the scraper bar assembly 121 includes a scraper bar support frame 1211, which is disposed below the lower surface 1231 of the floating assembly housing 123 and is connected to the drive assembly 122, capable of moving up and down under the drive of the drive assembly 122. The scraper bar assembly 121 also includes a scraper bar body 1212, which is connected to the scraper bar support frame 1211 and is configured to move between a first position and a second position as the scraper bar support frame 1211 moves. The scraper bar body 1212 has an arc-shaped structure, which is slightly downwardly curved in its natural state, and can clean some of the garbage on the ground when moving backward.

[0097] In some embodiments, the scraper support frame 1211 includes a guide portion or a guide groove; correspondingly, the scraper body 1212 includes a guide groove or a guide portion; the guide portion is inserted into the guide groove laterally, so that the scraper body 1212 and the scraper support frame 1211 are detachably connected through the cooperation of the guide portion and the guide groove.

[0098] In some embodiments, the scraper bar assembly 121 further includes a stopper 1213 disposed at at least one end of the scraper bar support frame 121, that is, at one or both ends of the scraper bar support frame 121. The stopper 1213 extends substantially perpendicular to the lower surface 1231 of the floating assembly housing 123 and moves up and down as the scraper bar support frame 1211 moves up and down, thereby preventing lateral movement of the scraper bar support frame 1211. Optionally, the lower surface 1231 of the floating assembly housing 123 has a groove at one end, and the stopper 1213 slides up and down within the groove, further limiting lateral and forward and backward movement of the scraper bar support frame 1211 and ensuring the stability of the scraper bar assembly 121 during cleaning.

[0099] In some embodiments, the stopper 1213 includes a stopper buckle 12131 disposed at the end of the stopper 1213 to prevent the stopper 1213 from falling off the lower surface 1231 of the floating assembly housing 123 when the stopper 1213 moves up and down. The stopper 1213 can be in the form of a hook or a cantilever, which is not limited to this.

[0100] In some embodiments, as Figure 5 As shown, the driving component 122 includes a power source 1221, which is, for example, a motor or a power output part of a motor, and realizes forward and reverse rotation according to the control of a driving signal to provide driving force in different directions; the driving component 122 also includes a driving part 1222, which is connected to the scraper support frame 1211, and the driving part 1222 is configured to drive the scraper support frame 1211 to move under the drive of the power source 1221.

[0101] In some embodiments, the driving unit 1222 includes a rotating arm 12221, which is connected to the output shaft of the power source 1221 and is configured to rotate under the drive of the power source 1221. The rotating arm 12221 can be a swing arm or a cam, which periodically outputs a downward force under the drive of the power source 1221. The driving unit 1222 also includes a limit stopper 12222, which is detachably or non-detachably connected to the rotating arm 12221 and is configured to move up and down with the rotation of the rotating arm 12221.

[0102] In some embodiments, the driving portion 1222 further includes an elastic member 12223, such as a coil spring, configured to provide a restoring force to the stopper. When the downward force exerted by the rotating arm 12221 on the stopper 12222 is removed, the stopper 12222 is driven by the elastic member 12223 to return to its upward position, and the scraper assembly 121 then returns to its second position.

[0103] In some embodiments, Figure 6 This is a structural diagram of the floating component in the falling state. Figure 6 As shown, the driving unit 1222 further includes a guide rod 12224, one end of which is connected to the limiting baffle 12222, and the other end of which passes through the lower surface 1231 of the floating assembly housing 123 and is fixedly connected to the scraper support frame 1211. The guide rod 12224 is configured to drive the scraper support frame 1211 to move up and down under the drive of the driving unit 1222. The limiting baffle 12222 moves downward under the action of the rotating arm 12221, compressing the elastic member 12223 and driving the scraper support frame 1211 and the scraper body 1212 downward through the guide rod 12224 to clean the cleaning surface in the corner.

[0104] In some embodiments, as Figure 5-Figure 6 As shown, the driving portion 1222 drives the scraper support frame 1211 substantially in the vertical direction, and the scraper body 1212 moves substantially in the vertical direction between the first position and the second position, so that the scraper body 1212 can clean close to the corner of the wall.

[0105] In other embodiments, such as Figure 7 As shown, Figure 7 This is a schematic diagram of the structure of a floating assembly according to another embodiment. The drive unit 1222 includes a gear set 12225, one end of which is connected to the power source 1221 and the other end to the scraper support frame 1211. Driven by the power source 1221, the gear set 12225 is configured to rotate the scraper support frame 1211 within a preset angle. The number of gears in the gear set 12225 is not specifically limited; for example, 3-5 gears can be provided for multi-stage transmission. When the cleaning brush head reaches a corner, the power source 1221 outputs a driving force, which is then transmitted through the gear set 12225. The gear set 12225 drives the scraper support frame 1211 to rotate within a preset angle, thereby driving the scraper body 1212 to rotate within a preset angle. This preset angle allows the scraper body 1212 to rotate substantially close to the surface to be cleaned, thereby facilitating the scraper body 1212's cleaning of the corner.

[0106] In some embodiments, the cleaning brush head further includes a switch, which can be either a structural or electronic switch. The switch is configured to allow a user to manually control whether the floating component performs a floating action based on the motion information. When the switch is off, the cleaning brush head will not perform the corresponding action even if the conditions for automatically controlling the floating component to perform a floating action are met. Only when the switch is on will the cleaning brush head perform the corresponding action if the conditions for automatically controlling the floating component to perform a floating action are met. This increases user control flexibility and meets the diverse needs of users.

[0107] The present disclosure also provides a cleaning device comprising a cleaning brush head as described above. The cleaning device may be, for example, a floor scrubber or mop, and the cleaning brush head serves as the cleaning unit of the cleaning device to perform the corresponding cleaning task. Optionally, the cleaning device may further include a handle, a water tank, a control unit, and other structures or components, which are not described in detail here.

[0108] The cleaning device provided herein uses a sensor wheel assembly 130 to sense the current motion state and direction of the cleaning brush head. When the cleaning brush head moves backward, the scraper bar assembly moves to a position adjacent to the surface to be cleaned, allowing the cleaning device to clean narrow spaces such as corners. When the cleaning device moves forward, the scraper bar assembly 121 can be stored because it is no longer needed to clean corners. When the cleaning device is moving forward or tends to move forward, the scraper bar assembly 121 is also kept in its second, stored position because its fall pushes debris away from the device, hindering its removal. Therefore, the present invention uses the sensor wheel assembly 130 to automatically control the raising and lowering of the scraper bar assembly based on the device's motion information to perform a scraping action, thereby automatically cleaning narrow spaces such as corners. This improves the cleaning performance of the cleaning device and enhances its intelligence and convenience. Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Reference should be made to the corresponding similarities between the various embodiments. As for the systems or devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the description of the methods.
