DETAILED DESCRIPTION

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] Therefore, an embodiment of the present disclosure provides a cleaning brush head, comprising: a sensing component configured to sense the posture information of the cleaning brush head, wherein the posture information includes at least one of the movement direction and the cleaning position of the cleaning brush head; a floating component configured to perform a floating action according to the posture information, the floating component comprising a scraping bar component, when the cleaning brush head reaches a preset cleaning position and / or moves in a first direction, the scraping bar component moves to the first position in a linear motion; when the cleaning brush head reaches outside the preset cleaning position and / or moves in a second direction, the scraping bar component moves to the second position in a linear motion.

[0058] The cleaning brush head provided by the present disclosure uses a sensing component to sense the position information of the cleaning brush head. The floating component then performs a floating action based on the position information. When the cleaning brush head reaches a preset cleaning position and / or 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 reaches outside the preset cleaning position and / or 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 sensing component, thereby automatically cleaning narrow spaces such as corners.

[0059] Optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0060] To more clearly describe the behavior of cleaning the brush head, such as Figure 1 As 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.

[0061] like Figure 1 As shown, an embodiment of the present application provides a cleaning brush head 100 for use in cleaning equipment such as floor scrubbers. The cleaning brush head includes a sensing component configured to sense the position information of the cleaning brush head, wherein the position information includes at least one of the movement direction of the cleaning brush head and the cleaning position. The movement direction includes a first direction and a second direction, wherein the first direction is front-to-back movement and the second direction is back-to-front movement. The cleaning position includes whether the cleaning brush head is located at the intersection of an obstacle and the cleaning surface or at a non-corner cleaning area of the cleaning surface. The position information of the cleaning brush head can be determined by at least one of the following sensing components: a stress sensor, a time-of-flight component, a line laser component, a radar component, an IMU, an encoder, or a Hall effect sensor. For example, a stress sensor at the front end of the roller brush 110 can determine whether the cleaning brush head 100 has collided with an obstacle, such as a wall, to detect that the front end of the cleaning brush head 100 has reached the edge of the obstacle. At this point, it can be determined that the corner between the obstacle and the surface to be cleaned is no longer accessible to 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 corner. Other sensing components can also be used for determination, which will not be described in detail.

[0062] 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 posture information. The floating component 120 includes a scraper component 121. When the cleaning brush head reaches a preset cleaning position and moves along a first direction, the scraper component 121 moves to the first position. For example, when the cleaning brush head reaches a corner position and is about to move along the first direction, the scraper component 121 moves to the first position. Figure 2When the cleaning brush head 100 reaches outside the preset cleaning position or 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.

[0063] 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 2 In some embodiments, when the cleaning brush head 100 reaches outside the preset cleaning position and moves in the second direction, the scraper assembly 121 moves to the second position, as shown in FIG. Figure 1 As shown, damage to the wiper strip assembly 121 due to reverse movement is avoided.

[0064] In some embodiments, as Figure 3 As shown, Figure 3 : This is a schematic diagram of the structure of a floating assembly according to an exemplary embodiment. The floating assembly 120 includes a floating assembly housing 123, which is disposed at the front end of the cleaning brush head 100. The floating assembly housing 123 can accommodate the roller brush 110, part of the sensing assembly, etc. The floating assembly 120 also includes a driving assembly 122, which is located within 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 based on the sensing result of the sensing assembly. 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 preventing the scraper body 1212 from contacting the obstacle during the rotational movement and damaging the scraper assembly 121.

[0065] In some embodiments, as Figure 3As 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] In some embodiments, as Figure 3 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.

[0070] 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.

[0071] 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.

[0072] In some embodiments, Figure 4 This is a structural diagram of the floating component in the falling state. Figure 4 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.

[0073] In some embodiments, as Figure 3-Figure 4 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.

[0074] In other embodiments, such as Figure 5 As shown, Figure 5This 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.

[0075] In some embodiments, the cleaning brush head further includes a switch, which may be a structural switch or an electronic switch. The switch is configured so that a user can manually control whether the floating component performs a floating action based on the posture 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 when the conditions for automatically controlling the floating component to perform a floating action are met. This increases the flexibility of user control and meets the different needs of users.

[0076] 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.

[0077] The cleaning device provided by the present disclosure senses the current position of the cleaning brush head and its direction of movement through a sensing component. When the cleaning brush head reaches a corner position such as a wall corner and moves backward, the scraper bar assembly moves to a position adjacent to the outside of the surface to be cleaned, and as the cleaning device moves backward, the narrow space such as the wall corner is cleaned. When the cleaning device is located in a narrow space other than a wall corner, the scraper bar assembly is not required to perform the corner cleaning task and can be located in a storage position. When the cleaning device is in a forward movement direction or a forward movement trend, the scraper bar assembly will push the garbage on the ground away from the cleaning device after it falls, which is not conducive to the cleaning of the garbage. Therefore, the scraper bar assembly will also be kept in the second storage position at this time. Therefore, the present disclosure can automatically control the lifting and lowering of the scraper bar assembly to perform the scraping action according to the posture information of the cleaning device through the sensing component, thereby automatically cleaning narrow spaces such as wall corners, improving the cleaning performance of the cleaning device, and also improving the intelligence and convenience of the cleaning device.

[0078] 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. References to the common and similar parts between the various embodiments will be sufficient. For the systems or devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, their descriptions are relatively simple; for relevant details, refer to the descriptions of the methods.

[0079] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
