Description

Technical Field

[0001] This application relates to the field of smart home device technology, and in particular to a floor brush and floor scrubber. Background Technology

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously drying wastewater and removing it from the site. It has advantages such as being environmentally friendly, energy-saving, and highly efficient.

[0003] In related technologies, floor scrubbers include a main body, floor brushes, and other structures. Due to the structural limitations of the floor brushes, when the floor scrubber moves forward along the surface being cleaned, less dirt (such as water stains) remains on the surface being cleaned, while when the floor scrubber moves backward along the surface being cleaned, more dirt remains on the surface being cleaned, resulting in poor cleaning performance and affecting the user experience. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application provides a floor brush and a floor scrubber. The floor brush can reduce the stains remaining on the surface being cleaned when the floor scrubber moves backward along the surface being cleaned, thereby improving the cleaning effect and enhancing the user experience.

[0005] Firstly, this application provides a ground brush, comprising:

[0006] The housing has a first end and a second end;

[0007] A roller brush is rotatably disposed on the housing and partially extends out of the housing, with the first end and the second end respectively located on both sides of the roller brush at a distance;

[0008] The smearing assembly includes a first scraper blade movably disposed at the first end and a second scraper blade disposed at the second end. The first scraper blade has a ground contact state that abuts against the surface being cleaned and a suspended state that is separated from the surface being cleaned.

[0009] Wherein, the first scraper is in the suspended state when the roller brush moves along the first direction, and in the ground state when the roller brush moves along the second direction opposite to the first direction, and the second scraper abuts against the surface being cleaned when the first scraper is in the suspended state, and the first direction is the direction from the second end to the first end.

[0010] The brush used according to the first aspect of this application has at least the following beneficial effects:

[0011] The floor brush of this application, through the coordinated arrangement of the housing, roller brush, and scraping component, allows the second scraper to remove stains remaining on the surface being cleaned due to the roller brush's friction when the floor brush moves forward along the surface being cleaned. Conversely, when the floor brush moves backward along the surface being cleaned, the first scraper removes stains remaining on the surface being cleaned due to the roller brush's friction. This reduces the amount of stains remaining on the surface being cleaned during the alternating forward and backward movements of the floor brush, improving the cleaning effect and enhancing the user experience.

[0012] In some embodiments, the smearing assembly further includes a first drive member and a linkage mechanism, wherein the first drive member drives the first smear blade to move up and down relative to the housing via the linkage mechanism, so that the first smear blade switches between the ground-contact state and the suspended state.

[0013] In some embodiments, the linkage mechanism includes a rotating rod and a lifting rod. The rotating rod is rotatably connected to the housing, and the lifting rod is rotatably connected to the rotating rod. The housing can restrict the lifting rod from moving horizontally. The first driving member is used to drive the rotating rod to rotate about the connection point with the housing, so as to drive the lifting rod to move vertically through the rotating rod. The first scraper is disposed at the bottom end of the lifting rod.

[0014] In some embodiments, a movable cavity is formed on the housing, and the rotating rod and the lifting rod are both installed in the movable cavity. The lifting rod and / or the first scraper are matched with the cavity wall of the movable cavity in the horizontal direction.

[0015] In some embodiments, the housing includes bent baffles spaced apart from the roller brush, the bent baffles covering at least a portion of the roller brush, the interior of the bent baffles forming the movable cavity, the extension trajectory of the movable cavity coinciding with the bending trajectory of the bent baffles.

[0016] In some embodiments, the movable cavity includes a vertical cavity extending along the vertical direction and a transition cavity communicating with the vertical cavity, the vertical cavity being bent relative to the transition cavity, the lifting rod being disposed in the vertical cavity, and the rotating rod being disposed in the transition cavity.

[0017] In some embodiments, the housing further includes a suction channel disposed adjacent to the second end, the inlet of the suction channel being opposite to a portion of the peripheral wall of the roller brush, and the suction channel being used to suck up dirt from the peripheral wall of the roller brush.

[0018] In some embodiments, the second scraper also abuts against the surface being cleaned when the first scraper is in the ground-contact state, and when the second scraper abuts against the surface being cleaned, it forms an arc-shaped inlet with a portion of the peripheral wall of the roller brush that communicates with the suction channel.

[0019] In some embodiments, the scraping assembly further includes a third scraper disposed adjacent to the suction channel, the third scraper being disposed within the housing and abutting against the peripheral wall of the roller brush, the third scraper being used to scrape off dirt from the roller brush.

[0020] In some embodiments, the floor brush further includes a roller rotatably mounted on the housing, the roller being used to drive the floor brush to move along the surface being cleaned toward the first direction or the second direction.

[0021] In some embodiments, the floor brush further includes a detection component and a controller communicatively connected to the detection component. The detection component is configured to detect the rotation direction of the roller, and the controller is configured to acquire the detection signal of the detection component and determine, based on the detection signal, whether the roller brush moves along the first direction or the second direction, so as to control the first scraper to switch between the ground-contact state and the suspended state.

[0022] In some embodiments, the detection assembly includes a grid disk disposed on the roller and two signal sensor groups spaced apart from each other in the housing;

[0023] Each of the signal sensor groups includes a pair of mating signal transmitters and signal receivers, with the grid disk located between the signal transmitters and the signal receivers;

[0024] The grid disk includes a plurality of grid openings distributed circumferentially and a baffle strip disposed between two adjacent grid openings. The grid openings are used to connect the signal transmitter to the corresponding signal receiver, and the baffle strips are used to disconnect the signal transmitter from the corresponding signal receiver.

[0025] Secondly, this application provides a floor scrubbing machine, including the floor brush described above.

[0026] The floor scrubbing machine according to the second aspect of this application has at least the following beneficial effects:

[0027] The floor scrubber of this application, equipped with the aforementioned floor brush, also possesses the same technical effects as the aforementioned floor brush. Through the coordinated arrangement of the housing, roller brush, and scraping assembly, when the floor brush moves forward along the surface to be cleaned, the second scraper removes the dirt remaining on the surface due to the roller brush's friction. When the floor brush moves backward along the surface to be cleaned, the first scraper removes the dirt remaining on the surface due to the roller brush's friction. This reduces the amount of dirt remaining on the surface during the alternating forward and backward movements of the floor brush, improving the cleaning effect and enhancing the user experience.

[0028] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

Detailed Implementation

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0044] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0045] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0046] In related technologies, floor scrubbers include a main body, floor brushes, and other structures. Due to the structural limitations of the floor brushes, when the floor scrubber moves forward along the surface being cleaned, less dirt remains on the surface; when it moves backward, more dirt remains, resulting in poor cleaning performance and affecting the user experience.

[0047] Addressing the issue that existing floor scrubbers often leave significant dirt residue on the surface being cleaned when moving backward, resulting in poor cleaning performance and a negative user experience, this application provides one or more embodiments of a floor brush. Through the coordinated arrangement of a housing 100, a roller brush 200, and a scraping assembly 300, when the floor brush moves forward along the surface being cleaned 600, a second scraper 320 removes dirt residue left on the surface 600 due to friction from the roller brush 200. When the floor brush moves backward along the surface 600, a first scraper 310 removes dirt residue left on the surface 600 due to friction from the roller brush 200. This reduces the amount of dirt remaining on the surface 600 during the alternating forward and backward movements of the floor brush, improving the cleaning effect and enhancing the user experience.

[0048] See Figure 1 and Figure 2 This application provides a floor brush, which includes a housing 100, a roller brush 200, and a smearing assembly 300.

[0049] The housing 100 has a first end 110 and a second end 120.

[0050] The roller brush 200 is rotatably disposed on the housing 100 and partially extends out of the housing 100. The first end 110 and the second end 120 are respectively located on both sides of the roller brush 200 at intervals.

[0051] The smearing assembly 300 includes a first scraper 310 movably disposed at a first end 110 and a second scraper 320 disposed at a second end 120. The first scraper 310 has a ground-contact state that abuts against the surface 600 being cleaned and a suspended state that is separated from the surface 600 being cleaned.

[0052] The first scraper 310 is suspended when the roller brush 200 moves along the first direction X1, and is in contact with the ground when the roller brush 200 moves along the second direction X2 opposite to the first direction X1. The second scraper 320 is in contact with the surface to be cleaned 600 when the first scraper 310 is suspended. The first direction X1 is the direction from the second end 120 to the first end 110.

[0053] It should be noted that, see Figure 1 and Figure 2The housing 100 is a carrier that supports structures such as the roller brush 200 and the scraping assembly 300, and may be, but is not limited to, made of plastic. The housing 100 may be provided with a roller brush cavity 170, which is configured to be open on one side facing the surface to be cleaned 600 (such as the ground). The roller brush 200 is rotatably mounted in the roller brush cavity 170, and a portion of the roller brush 200 extends out of the housing 100 through the opening of the roller brush cavity 170 to contact the surface to be cleaned 600 and achieve cleaning of the surface to be cleaned 600.

[0054] The first end 110 and the second end 120 on the housing 100 can be disposed on the inner wall of the brush cavity 170. The first end 110 and the second end 120 are located on opposite sides of the brush 200, and neither of them is in contact with the brush 200. With the housing 100 as a reference, the first end 110 is located at the front end of the housing 100, and the second end 120 is located at the rear end of the first end 110.

[0055] It should be understood that, see Figure 2 and Figure 3 The roller brush 200 is rotatably mounted on the housing 100 along its own axial direction, where the axial direction of the roller brush 200 refers to the direction of its central axis. The rotatable connection between the roller brush 200 and the housing 100 can be achieved, but is not limited to, by: a bearing being provided on the housing 100; the roller brush 200 having a rotating shaft; the roller brush 200 being mounted on the bearing via the rotating shaft; and a second driving member 160 being provided on the housing 100, which is drively connected to the rotating shaft on the roller brush 200 to drive the roller brush 200 to rotate around its own axial direction. The second driving member 160 can be, but is not limited to, a mechanism that combines a motor and a transmission structure. The motor is drively connected to the rotating shaft of the roller brush 200 via a transmission structure, which can be a belt drive structure, a chain and sprocket drive structure, etc.

[0056] The roller brush 200 has bristles on its peripheral wall. The bristles are shaped and easily deformed by external forces. The housing 100 may be equipped with a liquid supply mechanism (not shown in the figure) for spraying cleaning water onto the roller brush 200 and a suction channel 150 for sucking up dirt from the peripheral wall of the roller brush 200. When the roller brush is mopping along the surface 600 being cleaned, the liquid supply mechanism sprays cleaning water onto the peripheral wall of the roller brush 200, causing the bristles on the roller brush 200 to adhere to the cleaning water. As the roller brush 200 rolls along the surface 600 being cleaned, the bristles on the roller brush 200 rub against and are squeezed and bent, thereby picking up dirt (such as hair and fruit peels) from the surface 600 being cleaned. At the same time, the cleaning water adhering to the bristles washes the surface 600 being cleaned, and the suction channel 150 sucks up and removes the dirt from the bristles, thus achieving the cleaning of the surface 600 being cleaned.

[0057] It should also be noted that in the smudge-scraping assembly 300 of this application, the first scraper 310 and the second scraper 320 may be, but are not limited to, scraper blades, scraper brushes, etc. The first scraper 310 and the second scraper 320 are made of soft rubber material, which may be rubber, thermoplastic polyurethane rubber, polyvinyl chloride, etc.

[0058] When the first scraper 310 is in contact with the surface 600 being cleaned, it can remove stains from the surface 600. A small amount of remaining stain is spread out on the surface 600 in a thin layer, making it easier to evaporate. When the first scraper 310 is in a suspended state, separated from the surface 600, it does not contact the surface 600. The second scraper 320 works similarly and will not be described further.

[0059] The first scraper 310 can be movably disposed at the first end 110. The first scraper 310 can be movably disposed at the first end 110 of the housing 100. The first scraper 310 can reciprocate or reciprocate relative to the housing 100 to switch between the ground contact state and the suspended state.

[0060] The second scraper 320 can be directly fixed on the second end 120 of the housing 100. When the ground brush moves along the surface to be cleaned 600, the second scraper 320 is always in contact with the surface to be cleaned 600.

[0061] It should also be noted that, in this application, the direction in which the second end 120 points to the first end 110 is the direction in which the rear end of the housing 100 points to the front end, which also corresponds to the direction in which the entire floor brush works forward along the surface being cleaned 600. That is, the first direction X1 corresponds to the direction in which the entire floor brush works forward along the surface being cleaned 600. Conversely, the second direction X2 corresponds to the direction in which the entire floor brush works backward along the surface being cleaned 600.

[0062] The following combination Figure 3 and Figure 4 This application describes the floor brush operation in an embodiment:

[0063] See Figure 3When the entire floor brush moves along the first direction X1, that is, when the entire floor brush moves forward along the surface 600 to be cleaned, the first scraper 310 is in a suspended state separated from the surface 600 to be cleaned, while the second scraper 320 is in a state of contact with the surface 600 to be cleaned. As the entire floor brush moves forward, the roller brush 200 rolls forward along the surface 600 to perform the cleaning operation. Because the second scraper 320 is located behind the roller brush 200, it scrapes away stains (such as water stains) remaining on the surface 600 due to friction from the roller brush 200. A small amount of remaining stains are spread out on the surface 600 with a thinner layer, making them easier to evaporate. At the same time, because the first scraper 310 is in a suspended state, it will not scrape or push away the dirt on the surface 600 before the roller brush 200, allowing the roller brush 200 to effectively remove most of the dirt on the surface 600. This reduces the amount of dirt and stains remaining on the surface being cleaned 600, improves the cleaning effect of the floor brush on the surface being cleaned 600 when it moves forward along the surface being cleaned 600, and enhances the user experience.

[0064] See Figure 4 When the entire floor brush moves along the second direction X2, that is, when the entire floor brush works backward along the surface 600 being cleaned, the first scraper 310 is in a contact state with the surface 600 being cleaned. The entire floor brush moves backward, and the roller brush 200 rolls backward along the surface 600 being cleaned to perform the cleaning operation. Since the first scraper 310 is located behind the roller brush 200 along the second direction X2 at this time, the first scraper 310 scrapes away the stains remaining on the surface 600 being cleaned due to the friction of the roller brush 200. The small amount of stains remaining on the surface 600 being cleaned are spread out on the surface 600 with a thinner thickness, making them easier to evaporate. In this way, the dirt and stains remaining on the surface 600 being cleaned are reduced, improving the cleaning effect of the floor brush on the surface 600 being cleaned when working backward along the surface 600 being cleaned, and enhancing the user experience.

[0065] In addition, it should be noted that when the entire ground brush moves along the second direction X2, the second scraper 320 can be in a state of contact with the ground or in a state of suspension.

[0066] When actually using the floor brush, the user will operate the floor brush to alternately move forward and backward along the surface 600 to thoroughly clean the surface 600.

[0067] From the above description, it is easy to understand that the floor brush of this embodiment, through the cooperative arrangement of the housing 100, the roller brush 200, and the scraping component 300, allows the second scraper 320 to scrape away the stains remaining on the surface 600 after the roller brush 200 rubs against it when the floor brush moves forward along the surface 600 being cleaned. When the floor brush moves backward along the surface 600 being cleaned, the first scraper 310 scrapes away the stains remaining on the surface 600 after the roller brush 200 rubs against it. This reduces the amount of stains remaining on the surface 600 being cleaned during the alternating forward and backward movements of the floor brush, improves the cleaning effect on the surface 600 being cleaned, and enhances the user experience.

[0068] In some embodiments of this application, see Figure 3 and Figure 4 The scraping assembly 300 also includes a first drive member 330 and a linkage mechanism 340. The first drive member 330 drives the first scraper 310 to rise and fall relative to the housing 100 through the linkage mechanism 340, so that the first scraper 310 switches between a ground-contact state and a suspended state.

[0069] Specifically, a movable cavity 130 is formed on the housing 100, and the first driving member 330 and the linkage mechanism 340 are both installed in the movable cavity 130.

[0070] The linkage mechanism 340 may be, but is not limited to, a crank-slider mechanism, a crank-rocker structure, etc. In one embodiment, the linkage mechanism 340 is a crank-slider mechanism, the output end of the first drive member 330 is connected to the input end of the crank-slider mechanism, and the output end of the crank-slider mechanism is connected to the first scraper 310.

[0071] Thus, see Figure 3 and Figure 4 The first driving member 330 drives the first scraper 310 to move downward relative to the housing 100 through the linkage mechanism 340, so that the first scraper 310 comes into contact with the surface to be cleaned 600, thereby switching to the ground contact state. The first driving member 330 drives the first scraper 310 to move upward relative to the housing 100 through the linkage mechanism 340, so that the first scraper 310 separates from the surface to be cleaned 600, thereby switching to the suspended state. This achieves the effect of the first scraper 310 switching to the corresponding ground contact state or suspended state according to the overall movement direction of the floor brush.

[0072] Furthermore, the linkage mechanism 340 includes a rotating rod 341 and a lifting rod 342. The rotating rod 341 is rotatably connected to the housing 100, and the lifting rod 342 is rotatably connected to the rotating rod 341. The housing 100 can restrict the lifting rod 342 from moving in the horizontal direction X. The first driving member 330 is used to drive the rotating rod 341 to rotate around the connection point with the housing 100, so as to drive the lifting rod 342 to move in the vertical direction Z through the rotating rod 341. The first scraper 310 is provided at the bottom end of the lifting rod 342.

[0073] Specifically, the horizontal direction X refers to the length direction of the shell 100, and the vertical direction Z refers to the height direction of the shell 100.

[0074] The middle part of the rotating rod 341 is rotatably connected to the housing 100 via a first pin (not shown in the figure). One end of the rotating rod 341 is connected to the output end of the first driving member 330, and the other end of the rotating rod 341 is rotatably connected to the lifting rod 342 via a second pin (not shown in the figure). A vertical cavity 131 for the lifting rod 342 to move is formed on the housing 100. The lifting rod 342 is installed in the vertical cavity 131 along the vertical direction Z, and the two ends of the lifting rod 342 abut against the cavity wall of the vertical cavity 131 in the horizontal direction X. In this way, the housing 100 stops and limits the lifting rod 342 in the horizontal direction X, so that the lifting rod 342 only has the vertical direction Z degree of freedom of movement. The first scraper 310 is fixed to the bottom end of the lifting rod 342. The first driving member 330 can be configured as a linear drive structure such as a linear motor.

[0075] It is easy to understand, see Figure 3 When the entire local brush is operating in the first direction X1 (moving forward along the surface being cleaned 600), the first scraper 310 is in a suspended state. See also Figure 4 When the entire ground brush operates along the second direction X2 (operating backward along the surface to be cleaned 600), the first drive member 330 drives the rotating rod 341 to rotate counterclockwise by a preset angle around the connection point with the housing 100, so that the rotating rod 341 drives the lifting rod 342 connected to it to move down a preset distance relative to the housing 100, so that the first scraper 310 at the bottom of the lifting rod 342 abuts against the surface to be cleaned 600, thereby switching to the ground contact state.

[0076] When the entire brush switches from operating along the second direction X2 to operating along the first direction X1, the first driving member 330 drives the rotating rod 341 to rotate clockwise around the connection point with the housing 100 by a preset angle, so that the rotating rod 341 drives the lifting rod 342 connected to it to move upward relative to the housing 100 by a preset distance, so that the first scraper 310 at the bottom of the lifting rod 342 is completely separated from the surface being cleaned 600, thereby switching to the suspended state.

[0077] The aforementioned preset angle and preset distance can be set according to actual site requirements. For example, if the preset angle is 60° and the preset distance is 15mm, when the first driving member 330 drives the rotating rod 341 to rotate 60°, the lifting rod 342 will cause the first scraper 310 on it to move up or down 15mm relative to the housing 100. That is, when the first scraper 310 is in a suspended state, the first scraper 310 is 15mm away from the surface to be cleaned 600.

[0078] Furthermore, a movable cavity 130 is formed on the housing 100, and the rotating rod 341 and the lifting rod 342 are both installed in the movable cavity 130. The lifting rod 342 and / or the first scraper 310 are in a horizontal X-limiting fit with the cavity wall of the movable cavity 130.

[0079] Specifically, see Figure 4 and Figure 5 The first scraper 310 has a limiting block 311 at one end away from the surface to be cleaned 600. The two ends of the limiting block 311 abut against the two opposite cavity walls of the movable cavity 130. The limiting block 311 has a slot 3111. The bottom end of the lifting rod 342 has a protrusion 3421, which engages with the slot 3111.

[0080] In this way, on the one hand, the cavity wall of the movable cavity 130 limits the lifting rod 342 in the horizontal direction X, so that the lifting rod 342 only has the vertical direction Z degree of freedom of movement, ensuring the linearity of the lifting rod 342 driving the first scraper 310 to move up and down, and avoiding movement interference between the lifting rod 342, the first scraper 310 and the housing 100. On the other hand, the snap-fit ​​engagement between the lifting rod 342 and the first scraper 310 facilitates the disassembly and replacement of the first scraper 310, providing convenience for users to maintain the floor brush.

[0081] In addition, by installing both the rotating rod 341 and the lifting rod 342 inside the movable cavity 130 formed by the housing 100, it is possible to avoid motion interference between the rotating rod 341 and the lifting rod 342 and the roller brush 200, so that the first scraper 310 can switch accurately and smoothly between the ground contact state and the suspended state.

[0082] Further, see Figure 3 and Figure 4 The housing 100 includes bent baffles 140 spaced apart from the roller brush 200. The bent baffles 140 cover at least a portion of the roller brush 200. The interior of the bent baffles 140 forms a movable cavity 130. The extension trajectory of the movable cavity 130 coincides with the bending trajectory of the bent baffles 140.

[0083] Specifically, a brush cavity 170 is formed below the bent area of ​​the bent baffle 140, and the brush cavity 170 is open to the side facing the surface 600 being cleaned, so that the bent baffle 140 covers part of the area of ​​the brush 200.

[0084] By setting a bent baffle 140 covering at least part of the roller brush 200, the bent baffle 140 can stop the dirt thrown off the roller brush 200 during the rolling cleaning of the surface 600, so that the dirt is basically attached to the roller brush 200, improving the cleaning effect on the surface 600. By forming a movable cavity 130 on the bent baffle 140, the rotating rod 341 and the lifting rod 342 are installed in the movable cavity 130. The space of the bent baffle 140 can be fully utilized, avoiding interference between the rotating rod 341 and the lifting rod 342 and other structures on the floor brush. At the same time, the space occupied by the rotating rod 341 and the lifting rod 342 is reduced, making the overall structure of the floor brush more beautiful and compact, reducing production costs, and improving the user experience.

[0085] Further, see Figure 3 and Figure 4 The movable cavity 130 includes a vertical cavity 131 extending along the vertical direction Z and a transition cavity 132 communicating with the vertical cavity 131. The vertical cavity 131 is bent relative to the transition cavity 132. The lifting rod 342 is located in the vertical cavity 131 and the rotating rod 341 is located in the transition cavity 132.

[0086] It is understandable that the contour of the cavity formed by the connection of the vertical cavity 131 and the transition cavity 132 roughly matches the bending contour of the bent baffle 140. The vertical cavity 131 provides installation space for the lifting rod 342, which needs to move in the vertical Z direction, and the transition cavity 132 provides installation space for the rotating rod 341, which needs to rotate relative to the housing 100. In this way, the space of the bent baffle 140 is fully utilized, further reducing the space occupied by the rotating rod 341 and the lifting rod 342, making the overall structure of the floor brush more beautiful and compact, reducing production costs, and improving the user experience.

[0087] Furthermore, based on the bending shape of the bent baffle 140, the aforementioned linkage mechanism 340 is configured as a cooperating structure of the rotating rod 341 and the lifting rod 342. This allows for the adaptive use of the bending cavity of the bent baffle 140, eliminating the need for additional structural space on the housing 100 for mounting the linkage mechanism 340. This reduces the overall space occupied by the linkage mechanism 340 in the housing 100, making the overall structure of the floor brush more aesthetically pleasing and compact, reducing production costs, and improving the user experience.

[0088] In some embodiments of this application, see Figure 3 and Figure 4 The housing 100 also includes a suction channel 150 disposed adjacent to the second end 120. The inlet of the suction channel 150 is opposite to a portion of the peripheral wall of the roller brush 200. The suction channel 150 is used to suck up dirt on the peripheral wall of the roller brush 200.

[0089] Specifically, the floor brush also includes a suction mechanism (not shown in the figure) and a wastewater tank (not shown in the figure). The wastewater tank is connected to the suction channel 150. The suction mechanism is configured to generate suction force within the suction channel 150. The suction mechanism can be a fan, etc.

[0090] It is easy to understand that when the brush is used for cleaning, the suction channel 150 forms an adsorption force, which sucks away the dirt attached to the circumference of the brush 200, thus preventing the dirt from accumulating on the circumference of the brush and affecting the cleaning effect.

[0091] Further, see Figure 3 and Figure 4 The second scraper 320 also abuts against the surface 600 being cleaned when the first scraper 310 is in the ground state. When the second scraper 320 abuts against the surface 600 being cleaned, it forms an arc-shaped inlet 360 with part of the peripheral wall of the roller brush 200, which is connected to the suction channel 150.

[0092] Specifically, the second scraper 320 is detachably fixed to the second end 120 of the housing 100 so as to facilitate the removal, installation and replacement of the second scraper 320.

[0093] Understandably, when the brush edge is alternately moving forward or backward on the surface 600 being cleaned, the second scraper 320 is always in a contact state with the surface 600 being cleaned, so as to form an arc-shaped inlet 360 that connects with the suction channel 150 by a portion of the peripheral wall of the roller brush 200. The arc-shaped trajectory of the inlet 360 matches a portion of the rotation trajectory of the roller brush 200.

[0094] Thus, when the floor brush is performing cleaning operations, the roller brush 200 rolls counterclockwise along the surface being cleaned 6000. The dirt adhering to the perimeter of the roller brush 200 can be thrown into the suction channel 150 along the arc-shaped inlet 360 under the action of centrifugal force, so that the dirt on the perimeter of the roller brush 200 can be more efficiently sucked away by the suction channel 150.

[0095] Further, see Figure 3 and Figure 4 The scraping assembly 300 also includes a third scraper 350 disposed adjacent to the suction channel 150. The third scraper 350 is disposed inside the housing 100 and abuts against the peripheral wall of the roller brush 200. The third scraper 350 is used to scrape off dirt from the roller brush 200.

[0096] Specifically, the third scraper 350 can be, but is not limited to, a scraper, a scraper brush, or other similar structures. The third scraper 350 is made of a soft rubber material, such as rubber, thermoplastic polyurethane rubber, or polyvinyl chloride. The third scraper 350 is detachably fixed to the housing 100, facilitating its disassembly, assembly, and replacement.

[0097] The third scraper 350 and the second scraper 320 are located at the upper and lower ends of the inlet of the suction channel 150, respectively.

[0098] Thus, when the floor brush is performing cleaning operations, the roller brush 200 rolls counterclockwise along the surface being cleaned 6000. The dirt adhering to the peripheral wall of the roller brush 200 can be thrown into the suction channel 150 along the arc-shaped inlet 360 under the action of centrifugal force. At the same time, the third scraper 350 abuts against the peripheral wall of the roller brush 200 when the roller brush 200 rotates, thereby scraping off the dirt on the peripheral wall of the roller brush 200. This reduces the dirt adhering and accumulating on the peripheral wall of the roller brush 200, allowing the dirt on the peripheral wall of the roller brush 200 to be more efficiently sucked away by the suction channel 150.

[0099] In some embodiments of this application, see Figure 1 , Figure 3 , Figure 4 , Figure 6 The floor brush also includes a roller 400, which is rotatably mounted on the housing 100. The roller 400 is used to drive the floor brush to move along the surface being cleaned 600 in a first direction X1 or a second direction X2.

[0100] Specifically, there may be two rollers 400, which are arranged opposite each other along the width direction of the housing 100. The rollers 400 are constructed of rubber to increase the friction with the surface 600 being cleaned. Parts of the rollers 400 extend from the bottom of the housing 100 to contact the surface 600 being cleaned, thereby providing support for the entire floor brush.

[0101] The floor brush also includes a third drive unit (not shown in the figure) disposed in the housing 100. The third drive unit is connected to the roller 400 for driving the roller 400 to rotate. The third drive unit can be in the form of a motor and a reducer.

[0102] It should be noted that in this application, when the roller 400 rotates clockwise, the roller 400 drives the entire floor brush to work forward along the surface being cleaned 600, and when the roller 400 rotates counterclockwise, the roller 400 drives the entire floor brush to work backward along the surface being cleaned 600.

[0103] The rotation of roller 400 and roller brush 200 are independent and complementary. In this application, when the floor brush is performing cleaning operations, roller brush 200 rotates counterclockwise around its own axis, so the movement of roller brush 200 does not interfere with the movement of roller 400.

[0104] It is easy to understand that, through the setting of the roller 400, the roller 400 provides support for the overall structure of the floor brush, and at the same time drives the entire floor brush to clean along the surface to be cleaned 600.

[0105] Further, see Figure 6 and Figure 7 The floor brush also includes a detection component 500 and a controller that is communicatively connected to the detection component 500. The detection component 500 is configured to detect the rotation direction of the roller 400. The controller is used to acquire the detection signal of the detection component 500 and determine the movement of the roller brush 200 along the first direction X1 or the second direction X2 based on the detection signal, so as to control the first scraper 310 to switch between the ground contact state and the suspended state.

[0106] Specifically, the roller 400 can rotate in two directions: clockwise and counterclockwise. When the roller 400 rotates clockwise, it drives the entire floor brush to move forward along the surface being cleaned 600, and the roller brush 200 moves in the first direction X1. When the roller 400 rotates counterclockwise, it drives the entire floor brush to move backward along the surface being cleaned 600, and the roller brush 200 moves in the second direction X2.

[0107] The detection component 500 can be configured as a grating encoder, the controller is configured as a microprocessor based on single-chip microcomputer program control, the detection component 500 and the aforementioned first drive component 330 are communicatively connected to the controller, the first drive component 330 is configured as a linear motor, and the linkage mechanism 340 is configured as a crank-slider structure.

[0108] It should be understood that when the roller 400 rotates clockwise, the roller 400 drives the entire floor brush to move along the first direction X1. At this time, the roller brush 200 works forward along the surface to be cleaned 600. The detection component 500 detects that the rotation direction of the roller 400 is clockwise. The controller obtains the detection signal from the detection component 500 and controls the first drive component 330 to move based on the detection signal. The first drive component 330 drives the first scraper 310 to move upward relative to the housing 100 through the linkage mechanism 340, so that the first scraper 310 moves to a suspended state. This prevents the first scraper 310 from scraping and pushing the dirt on the surface to be cleaned 600 before the roller brush 200, so that the dirt on the surface to be cleaned 600 can be basically adhered and removed by the roller brush 200.

[0109] Similarly, when the roller 400 rotates counterclockwise, the roller 400 drives the entire floor brush to move in the second direction X2. At this time, the roller brush 200 works backward along the surface to be cleaned 600. The detection component 500 detects that the rotation direction of the roller 400 is counterclockwise. The controller obtains the detection signal from the detection component 500 and controls the first drive component 330 to move based on the detection signal. The first drive component 330 drives the first scraper 310 to move downward relative to the housing 100 through the linkage mechanism 340, so that the first scraper 310 moves to the ground state, so that the first scraper 310 can scrape off the stains remaining on the surface to be cleaned 600, ensuring the cleaning effect.

[0110] It is easy to understand that the floor brush of this application, through the cooperation of the detection component 500 and the controller, enables the first scraper 310 to automatically switch to the corresponding suspended state or grounded state based on the movement of the roller brush 200 along the first direction X1 or the second direction X2, thereby improving the cleaning effect of the roller brush 200 on the surface 600 to be cleaned.

[0111] Further, see Figure 6 , Figure 7 and Figure 8 The detection assembly 500 includes a grid disk 510 mounted on a roller 400 and two signal sensor groups 520 spaced apart from the housing 100. Each signal sensor group 520 includes a pair of cooperating signal transmitters 521 and signal receivers 522, with the grid disk 510 located between the signal transmitters 521 and the signal receivers 522. The grid disk 510 includes a plurality of grid openings 511 distributed circumferentially and baffles 512 disposed between adjacent grid openings 511. The grid openings 511 are used to connect the signal transmitters 521 and the corresponding signal receivers 522, and the baffles 512 are used to disconnect the signal transmitters 521 and the corresponding signal receivers 522.

[0112] Specifically, the grid disk 510 is constructed as a circular grating disk, and is mounted inside the rotating shaft of the roller 400 or inside the output shaft of the third drive unit. The signal transmitter 521 is an LED emitting light, and the signal receiver 522 is an LED receiving light used to receive the light emitted by the LED emitting light. The LED emitting light and the LED receiving light face each other in a direction parallel to the axis of the roller 400. Both the LED emitting light and the LED receiving light are fixed on the housing 100 and remain relatively stationary with the housing 100, and do not rotate with the roller 400.

[0113] It is easy to understand, see Figure 8 When the vertical projection of one group of LED transmitters and LED receivers relative to the grid disk 510 is within a grid opening 511 on the grid disk 510, the optical path between the group of LED transmitters and LED receivers is connected, and the group of LED transmitters and LED receivers forms a connection.

[0114] See Figure 8 When the vertical projection of one of the LED emitters or receivers relative to the grid disk 510 is on a baffle 512 on the grid disk 510, the light emitted by the LED emitter is blocked by the baffle 512. At this time, the light path between the LED emitter and receiver is broken, and the connection between the LED emitter and receiver is disconnected.

[0115] Thus, when the roller 400 rotates, the two sets of LED transmitters and receivers will generate two corresponding electrical signals. A disconnect signal is generated when one set of LED transmitters and receivers is disconnected, and a conduction signal is generated when both sets are connected. When the roller 400 rotates clockwise or counterclockwise, the multiple conduction and disconnection signals generated by the two sets of LED transmitters and receivers have corresponding phase differences, i.e., a specific sequence.

[0116] The controller determines the rotation direction of the roller 400 based on the phase difference between multiple on signals and multiple off signals, thereby accurately determining whether the roller brush 200 moves along the first direction X1 or the second direction X2. Then, by controlling the action of the first drive member 330 and the corresponding linkage mechanism 340, the first scraper 310 automatically switches to the corresponding suspended state or grounded state based on the movement of the roller brush 200 along the first direction X1 or the second direction X2, thereby improving the cleaning effect of the roller brush 200 on the surface 600 being cleaned.

[0117] It is easy to understand that, through the coordinated arrangement of the grid disc 510 and two pairs of signal sensor groups 520, the two pairs of signal sensor groups 520 can generate multiple on signals and multiple off signals during the rotation of the grid disc 510 driven by the roller 400. The controller can determine the rotation direction of the roller 400 based on the phase difference between the multiple on signals and the multiple off signals, and thus accurately determine whether the roller brush 200 moves along the first direction X1 or the second direction X2. Then, by controlling the action of the first driving member 330 and the corresponding linkage mechanism 340, the first scraper 310 automatically switches to the corresponding suspended state or grounded state based on the movement of the roller brush 200 along the first direction X1 or the second direction X2, thereby improving the cleaning effect of the roller brush 200 on the surface 600 being cleaned.

[0118] In addition, see Figure 9 This application also provides a floor scrubber, which includes the floor brush of any of the above embodiments. The floor scrubber also has a handle structure 700, which is rotatably connected to the housing 100. The handle structure 700 is designed to facilitate user operation and control of the overall movement direction of the floor brush, making it convenient for users to manually operate and use the floor scrubber.

[0119] It is easy to understand that the floor scrubber of this application embodiment, due to the configuration of the aforementioned floor brush, also has the same technical effect brought by the aforementioned floor brush. That is, through the cooperative arrangement of the housing 100, the roller brush 200 and the scraping component 300, when the floor brush works forward along the surface to be cleaned 600, the second scraper 320 scrapes away the stains remaining on the surface to be cleaned 600 due to the friction of the roller brush 200. When the floor brush works backward along the surface to be cleaned 600, the first scraper 310 scrapes away the stains remaining on the surface to be cleaned 600 due to the friction of the roller brush 200. This reduces the stains remaining on the surface to be cleaned 600 during the alternating forward and backward work of the floor brush, improves the cleaning effect on the surface to be cleaned 600, and enhances the user experience.

[0120] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0121] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
