Description

Technical Field

[0001] This disclosure belongs to the field of cleaning equipment technology, specifically relating to a floor brush and cleaning equipment. Background Technology

[0002] As a mainstream indoor cleaning device, the cleaning range and efficiency of a vacuum cleaner's floor brush directly affect the overall cleaning effect. With the upgrading of cleaning needs, users are increasingly demanding cleaning of hard-to-reach areas, especially baseboards and other wall areas, which are often neglected and accumulate dust, hair, and other debris, seriously impacting indoor hygiene. Current floor brush designs are primarily for floor cleaning and cannot reach deep into areas close to the baseboards.

[0003] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a floor brush and cleaning device. Summary of the Invention

[0004] The purpose of this disclosure is to provide a floor brush and cleaning device that can solve the problem that floor brushes cannot efficiently clean wall surfaces and baseboard areas.

[0005] To achieve the above objectives, a specific embodiment of this disclosure provides a floor brush, comprising: a housing; a first dust collection channel disposed within the housing and communicatively connected to a negative pressure source, the first dust collection channel including a first air inlet facing the surface to be cleaned; a roller brush disposed near the first air inlet; a second dust collection channel disposed within the housing and communicatively connected to the negative pressure source, the second dust collection channel including a second air inlet formed on the side wall of the housing; and a sealing member movably disposed on the housing, the sealing member closing the second air inlet when moved to a first position and opening the second air inlet when moved to a second position.

[0006] In one or more embodiments of this disclosure, at least a portion of the plugging member protrudes from the sidewall, the plugging member being adapted to frictionally contact a target side surface to drive the plugging member to the second position, the target side surface being substantially parallel to the sidewall.

[0007] In one or more embodiments of this disclosure, the sealing member is driven to move to the second position while in the direction of travel of the ground brush and while the sealing member is in frictional contact with the target lateral surface.

[0008] In one or more embodiments of this disclosure, the floor brush further includes an elastic member that cooperates with the sealing member, the elastic member having an elastic potential energy to reset the sealing member to the first position.

[0009] In one or more embodiments of this disclosure, the housing includes a guide groove for mounting the sealing member, the guide groove extending at least partially parallel to the travel direction of the floor brush, the sealing member being movable along the guide groove between a first position and a second position.

[0010] In one or more embodiments of this disclosure, the sealing member is provided with bristles that can contact the target lateral surface.

[0011] In one or more embodiments of this disclosure, the bristles are evenly arranged on the side of the sealing member opposite to the housing; and / or, the bristles are flexible bristles; and / or, the length of the bristles is 5mm-10mm.

[0012] In one or more embodiments of this disclosure, the floor brush includes two second dust collection channels, and the second air inlets of the two second dust collection channels are formed on the two opposite sidewalls of the housing.

[0013] In one or more embodiments of this disclosure, the floor brush further includes an air intake shroud that can communicate with the dust collection pipe of the cleaning equipment, the cross-sectional dimensions of the air intake shroud gradually decreasing in the air intake direction, and a portion of the first dust collection channel is formed inside the air intake shroud.

[0014] The air intake hood has a side opening, and the second dust collection channel is connected to the first dust collection channel through the side opening.

[0015] In one or more embodiments of this disclosure, the floor brush further includes an airflow branch pipe extending laterally within the housing, one end of the airflow branch pipe forming the second air inlet and the other end being connected to the negative pressure source.

[0016] A specific embodiment of this disclosure also provides a cleaning device, including the floor brush described above.

[0017] The beneficial effects of this disclosure, which differ from existing technologies, include:

[0018] This disclosed floor brush, by incorporating a first dust collection channel, a second dust collection channel, and a sealing component that cooperates with the second air inlet, achieves automatic adaptation and efficient balance between floor cleaning and baseboard cleaning, effectively improving cleaning efficiency. Specifically, in floor cleaning mode, the sealing component is in the first position and the second air inlet is closed, ensuring that all suction power from the negative pressure source is concentrated in the first dust collection channel, forming a stable and strong negative pressure environment at the first air inlet. This ensures that the roller brush can efficiently collect dust and debris from the surface to be cleaned, avoiding the negative pressure dispersion problem caused by the side-mounted second air inlet, and maintaining high floor cleaning efficiency. When it is necessary to clean the side surfaces such as baseboards, the sealing component moves to the second position to open the second air inlet, extending the range of the negative pressure source to the second dust collection channel. This allows dust and debris located on the side wall of the casing to be effectively sucked in from the second air inlet, achieving thorough cleaning of hard-to-reach areas such as baseboards on walls. Therefore, the floor brush disclosed herein not only ensures the strength and efficiency of floor cleaning, but also solves the long-standing problem of ineffective cleaning of the baseboard area, significantly improving the overall cleaning effect and user experience of the cleaning equipment.

[0019] In this disclosed floor brush, at least a portion of the sealing element protrudes from the sidewall, allowing it to directly rub against a target side surface such as a baseboard. Therefore, when the floor brush performs cleaning operations near the target side surface, the physical contact between the two automatically triggers the displacement of the sealing element, thereby achieving cleaning of the baseboard area.

[0020] In the floor brush disclosed herein, the sealing element is driven to move to a second position when it is in the direction of travel of the floor brush and in frictional contact with the target side surface. This design is more in line with users' habits of using floor brushes, and the second air intake can be opened accordingly by the direction of travel of the floor brush, ensuring the smoothness and reliability of switching cleaning surfaces.

[0021] In the floor brush disclosed herein, after the floor brush leaves the target side surface such as the baseboard, the external friction force acting on the sealing element begins to disappear. At this time, the elastic potential energy accumulated in the elastic element is released, driving the sealing element to automatically and reliably return from the second position to the first position, closing the second air inlet. Therefore, it can automatically switch to cleaning the floor without requiring additional operation from the user, improving the convenience of switching. At the same time, closing the second air inlet by the sealing element ensures that the suction power is not dispersed by the second dust collection channel, thereby improving dust collection efficiency.

[0022] In the floor brush disclosed herein, the housing includes a guide groove for mounting a sealing element. The guide groove extends at least partially parallel to the travel direction of the floor brush, and the sealing element is movable along the guide groove between a first position and a second position. Therefore, the design of the guide groove provides precise guidance and stable support for the reciprocating movement of the sealing element between the first and second positions.

[0023] In this disclosed floor brush, the sealing component is provided with bristles that can contact the target side surface. The bristles on the sealing component have several advantages. First, as the part that contacts the target side surface, the bristles' flexibility effectively buffers the impact force upon contact, preventing scratches or damage to the wall or baseboard. Second, during cleaning, the bristles can penetrate deep into the fine irregularities of the baseboard surface, sweeping away dust accumulated in its crevices and guiding it to the vicinity of the second air inlet, where it works in conjunction with negative pressure suction to achieve deep cleaning. Furthermore, the bristles also increase the friction with the target side surface, ensuring that the sealing component can smoothly open the second air inlet.

[0024] The disclosed floor brush includes two second dust collection channels, and the second air inlets of the two second dust collection channels are formed on two opposite sidewalls of the housing. By providing two second dust collection channels, the floor brush can meet the cleaning needs of either the left or right side of the baseboard. Therefore, regardless of which side of the wall the floor brush travels along, the corresponding second air inlet can be opened and cleaned with the cooperation of the sealing component. This not only expands the product's applicable scenarios but also avoids the inconvenience of users having to repeatedly adjust the direction of the floor brush, further improving cleaning efficiency and convenience.

[0034] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0035] As a mainstream indoor cleaning device, the cleaning range and efficiency of the floor brush in a vacuum cleaner directly affect the overall cleaning effect. With the upgrading of cleaning needs, users are increasingly demanding cleaning of hard-to-reach areas, especially wall areas such as baseboards, which are often neglected and accumulate dust, hair, and other debris, seriously affecting indoor hygiene. Current floor brush designs are primarily for floor cleaning and cannot reach the baseboard area. To address this technical issue, some cleaning devices have attempted to optimize the edge-to-edge distance, such as by using longer nylon bristles and thinner edges to achieve closer edge cleaning. However, this only improves the cleaning effect on the floor edges and cannot clean the baseboard surface, leaving it constantly dirty and becoming a cleaning bottleneck.

[0036] To address the cleaning of baseboards and other wall surfaces, current designs involve attaching a scouring pad to the side of a floor brush, using the pad to rub and wipe away stains. However, this solution has significant drawbacks: firstly, the cleaning principle is "adhesive," failing to draw dirt into the vacuum cleaner; it merely transfers the stains to the scouring pad's surface, resulting in incomplete cleaning; secondly, the scouring pad easily becomes saturated with dirt, causing secondary contamination of clean baseboards and white walls during cleaning, thus reducing cleaning efficiency.

[0037] In addition, existing designs also achieve multi-directional cleaning by connecting the side nozzle to the floor brush, but this requires manually driving the side nozzle to rotate and switch, which is cumbersome. Furthermore, the side nozzle is always open, which causes the negative pressure at the bottom of the floor brush to disperse, affecting the vacuum level and dust removal efficiency of floor cleaning. It is impossible to achieve a balance between the performance of cleaning baseboards and normal floors.

[0038] Based on the existing design, the existing floor brushes are still unable to effectively clean wall areas such as baseboards, and cannot balance the cleaning power of normal floor cleaning with that of baseboard area cleaning, resulting in incomplete cleaning.

[0039] Based on the above technical issues, please refer to Figures 1 to 6 This disclosure provides a floor brush in one embodiment, which can effectively improve the cleaning efficiency of walls such as baseboards, and can also take into account the cleaning power of normal floors and baseboard areas. This disclosure provides a floor brush including a housing 1, a first dust collection channel 2, a roller brush 3, a second dust collection channel 4, and a sealing member 5. The first dust collection channel 2 is disposed within the housing 1 and can communicate with a negative pressure source. The first dust collection channel 2 includes a first air inlet 21 facing the surface to be cleaned. The roller brush 3 is disposed near the first air inlet 21. The second dust collection channel 4 is disposed within the housing 1 and can communicate with a negative pressure source. The second dust collection channel 4 includes a second air inlet 41 formed on the side wall of the housing 1. The sealing member 5 is movably disposed on the housing 1. When the sealing member 5 moves to a first position, it closes the second air inlet 41, and when it moves to a second position, it opens the second air inlet 41. In this embodiment, the side wall of the housing 1 is a side wall that is set approximately perpendicular to the axis of the roller brush 3. This side wall can contact the side surfaces such as the baseboard when the floor brush is moving.

[0040] When only the surface to be cleaned (such as the floor) needs to be cleaned, the sealing member 5 is in the first position and the second air inlet 41 is closed, ensuring that all the suction power of the negative pressure source is concentrated in the first dust collection channel 2. A stable and strong negative pressure environment is formed at the first air inlet 21, thereby ensuring that the roller brush 3 can efficiently collect dust and debris from the surface to be cleaned. This avoids the problem of negative pressure dispersion caused by the side-mounted second air inlet 41, maintaining high floor cleaning efficiency. When it is also necessary to clean side surfaces such as baseboards, the sealing member 5 moves to the second position to open the second air inlet 41. The range of the negative pressure source extends to the second dust collection channel 4, allowing dust and debris located on the side wall of the housing 1 to be effectively sucked in from the second air inlet 41, achieving thorough cleaning of hard-to-clean areas such as baseboards on the walls. It should be understood that side surfaces are not limited to baseboards, but include any surface at a certain angle to the surface to be cleaned, such as the hard-to-clean parts of ordinary side walls or furniture placed on the surface to be cleaned near the ground. Therefore, the floor brush disclosed herein not only ensures the strength and efficiency of floor cleaning, but also solves the long-standing problem of ineffective cleaning of the baseboard area, significantly improving the overall cleaning effect and user experience of the cleaning equipment.

[0041] Furthermore, in order to enable the sealing member 5 to adaptively open the second air inlet 41, in the floor brush of this disclosure, at least a portion of the sealing member 5 protrudes from the sidewall, and the sealing member 5 is adapted to make frictional contact with the target side surface to drive the sealing member 5 to move to a second position, where the target side surface is substantially parallel to the sidewall. Therefore, when the floor brush performs cleaning operations near the target side surface, the physical contact between the two can automatically trigger the displacement of the sealing member 5 to correspondingly achieve cleaning of the baseboard area.

[0042] Furthermore, in order to ensure that the opening of the second air inlet 41 by the sealing component 5 is more in line with the user's usage habits, in the floor brush of this disclosure, when the sealing component 5 is in the direction of travel of the floor brush and when the sealing component 5 is in frictional contact with the target side surface, the sealing component 5 is driven to move to the second position.

[0043] Furthermore, in order to enable the sealing member 5 to adaptively close the second air inlet 41, the floor brush of this disclosure also includes an elastic member 6 that cooperates with the sealing member 5, the elastic member 6 having elastic potential energy to reset the sealing member 5 to the first position.

[0044] Furthermore, in order to enhance the movement stability of the sealing member 5 in the first and second positions, in the floor brush of this disclosure, the housing 1 includes a guide groove 71 for mounting the sealing member 5, the extension direction of the guide groove 71 being at least partially parallel to the travel direction of the floor brush, and the sealing member 5 being movable along the guide groove 71 between the first and second positions.

[0045] Furthermore, in order to improve the cleaning power on the target side surface, in the floor brush of this disclosure, the sealing member 5 is provided with bristles 8 that can contact the target side surface.

[0046] Furthermore, in order to expand the applicable scenarios of the floor brush, the floor brush disclosed herein includes two second dust collection channels 4, and the second air inlets 41 of the two second dust collection channels 4 are formed on two opposite side walls of the housing 1.

[0047] The technical solutions of this disclosure are further described in detail below with reference to specific embodiments and accompanying drawings.

[0048] Please refer to Figure 1 and Figure 2 In one embodiment of this disclosure, the floor brush includes a housing 1, a first dust collection channel 2, a roller brush 3, a second dust collection channel 4, and a sealing component 5.

[0049] Please refer to Figure 2 and Figure 3The first dust collection channel 2 is disposed within the housing 1 and can communicate with a negative pressure source. The first dust collection channel 2 includes a first air inlet 21 facing the surface to be cleaned, and a roller brush 3 is disposed near the first air inlet 21. Therefore, when cleaning a surface (such as a floor), the roller brush 3 can be used for floor cleaning operations. Combined with the negative pressure effect of the negative pressure source, dust and debris can enter the first dust collection channel 2 through the first air inlet 21, thereby achieving efficient cleaning of the floor. The aforementioned negative pressure source can be a fan within the cleaning equipment, which provides negative pressure to achieve the corresponding floor cleaning operation.

[0050] Please refer to Figure 2 and Figure 4 The second dust collection channel 4 is located inside the housing 1 and can be connected to a negative pressure source. The second dust collection channel 4 includes a second air inlet 41 formed on the side wall of the housing 1, and the side wall is approximately perpendicular to the axis of the roller brush 3; please refer to Figure 5 The sealing element 5 is movably mounted on the housing 1. When the sealing element 5 moves to the first position, it closes the second air inlet 41, and when it moves to the second position, it opens the second air inlet 41. Therefore, when cleaning wall areas such as baseboards, the sealing element 5 can be in the second position with the second air inlet 41 open. Similarly, combined with the negative pressure effect of the negative pressure source, dust and debris can enter the second dust collection channel 4 through the second air inlet 41, thereby achieving the cleaning operation of the target side surface.

[0051] In the floor brush disclosed herein, when only the surface to be cleaned (such as the floor) needs to be cleaned, the sealing member 5 can be in the first position and the second air inlet 41 can be closed. This ensures that all the suction power of the negative pressure source is concentrated in the first dust collection channel 2, forming a stable and strong negative pressure environment at the first air inlet 21. This ensures that the roller brush 3 can efficiently collect dust and debris from the surface to be cleaned, avoiding the negative pressure dispersion problem caused by the side-mounted second air inlet 41, and maintaining high floor cleaning efficiency. When it is also necessary to clean side surfaces such as baseboards, the sealing member 5 moves to the second position to open the second air inlet 41. The range of the negative pressure source extends to the second dust collection channel 4, allowing dust and debris located on the side wall of the housing 1 to be effectively sucked in from the second air inlet 41, achieving thorough cleaning of hard-to-reach areas such as baseboards on walls. Therefore, the floor brush of this disclosure not only ensures the strength and efficiency of floor cleaning but also solves the problem of the long-term difficulty in effectively cleaning the baseboard area, significantly improving the overall cleaning effect and user experience of the cleaning equipment.

[0052] Please refer to Figure 2 , Figure 3 and Figure 4The first dust collection channel 2 and the second dust collection channel 4 can be solid pipes to achieve the cleaning function of the floor or baseboard area. Specifically, in this embodiment, the floor brush also includes an airflow branch pipe extending laterally within the housing 1, one end of which forms a second air inlet 41, and the other end can be connected to a negative pressure source. The airflow branch pipe can be configured as the second dust collection channel 4 in this embodiment.

[0053] Please refer to Figure 3 and Figure 4 In this embodiment, the first dust collection channel 2 and the second dust collection channel 4 can be connected. Therefore, dust and debris entering the second dust collection channel 4 through the second air inlet 41 can flow into the first dust collection channel 2 and eventually be discharged. Specifically, the floor brush also includes an air intake cover 22 that can communicate with the dust collection pipe of the cleaning equipment. The cross-sectional dimension of the air intake cover 22 gradually decreases in the air intake direction, and part of the first dust collection channel 2 is formed inside the air intake cover 22. A side opening is provided on the air intake cover 22, and the second dust collection channel 4 communicates with the first dust collection channel 2 through the side opening. The opening design of the air intake cover 22 can be correspondingly formed into a funnel shape to ensure the cleaning coverage of the floor.

[0054] Please combine Figure 3 and Figure 4 In other embodiments, the first dust collection channel 2 and the second dust collection channel 4 may not be connected. For example, the second dust collection channel 4 may be directly connected to a negative pressure source. Through the negative pressure of the negative pressure source, dust and debris can directly enter the second dust collection channel 4 through the second air inlet 41, thus achieving the same cleaning operation on the side surface of the target. Since both the first dust collection channel 2 and the second dust collection channel 4 are connected to a negative pressure source, the second dust collection channel 4 may disperse the negative pressure. Therefore, in this disclosure, when cleaning the ground, the aforementioned sealing member 5 can effectively seal the second air inlet 41 to ensure a stable and strong negative pressure environment is formed at the first air inlet 21.

[0055] Please refer to Figure 1 and Figure 5 At least a portion of the sealing element 5 protrudes from the sidewall, and the sealing element 5 is adapted to make frictional contact with the target side surface to drive the sealing element 5 to move to a second position, where the target side surface is substantially parallel to the sidewall. Therefore, by having at least a portion of the sealing element 5 protrude from the sidewall, it is able to make direct frictional contact with the target side surface, such as the baseboard. Thus, when the ground brush performs cleaning operations near the target side surface, the physical contact between the two can automatically trigger the displacement of the sealing element 5 to correspondingly achieve cleaning of the baseboard area.

[0056] Please refer to Figure 1When the floor brush is traveling in the same direction and the sealing element 5 is in frictional contact with the target side surface, the sealing element 5 is driven to move to the second position. This design better suits users' habits when using the floor brush. The second air inlet 41 can be opened correspondingly by the direction of the floor brush's travel, ensuring smoothness and reliability in switching cleaning surfaces. This is because users usually drive the floor brush forward for cleaning, while the frictional contact between the sealing element 5 and the target side surface causes the sealing element 5 to move backward, opening the second air inlet 41 and facilitating a smooth switch to cleaning baseboards and other wall surfaces.

[0057] It's important to note that when the floor brush cleans wall areas such as baseboards, it doesn't mean the brush doesn't clean the floor. In fact, while cleaning wall areas like baseboards, the floor is also being cleaned. Compared to scenarios where only the floor is cleaned, the suction power is dispersed by the second dust collection channel 4. Understandably, when the user adjusts the direction of the floor brush to clean surfaces near the target side, the sidewall of the housing 1 can be kept away from the target side surface, while the front wall of the housing 1 in the direction of travel is closer to the target side surface, yet the suction power of the floor brush on the floor is still maintained.

[0058] Please refer to Figure 1 and Figure 5 The floor brush also includes an elastic element 6 that cooperates with the sealing element 5. The elastic element 6 has elastic potential energy to reset the sealing element 5 to the first position. In this embodiment, after the floor brush leaves the target side surface such as the baseboard, the external friction force acting on the sealing element 5 begins to disappear. At this time, the elastic potential energy accumulated in the elastic element 6 is released, driving the sealing element 5 to automatically and reliably return from the second position to the first position of closing the second air inlet 41. Therefore, it can automatically switch to cleaning the floor without requiring additional operation from the user, improving the convenience of switching. At the same time, closing the second air inlet 41 by the sealing element 5 ensures that the suction power is not dispersed by the second dust collection channel 4, thereby improving dust collection efficiency. The elastic element 6 mentioned above can be a compression spring or an elastic element 6 made of other elastic materials such as a spring sheet.

[0059] Please refer to Figure 1 and Figure 5 It is understandable that the switching between the first and second positions of the sealing component 5 in this embodiment mainly utilizes its mechanical structure design, combined with the frictional force provided by the target side surface and the elastic potential energy of the elastic component 6, to adaptively switch positions according to the actual cleaning scenario. In other embodiments, the switching between the first and second positions of the sealing component 5 can also be driven by automated equipment such as cylinders or motors. Alternatively, the position of the sealing component 5 can be manually adjusted based on user needs, and this disclosure does not impose any limitations on this.

[0060] Please refer to Figure 4 and Figure 5 The housing 1 includes a guide groove 71 for mounting the sealing member 5. The extending direction of the guide groove 71 is at least partially parallel to the traveling direction of the floor brush. The sealing member 5 can move along the guide groove 71 between a first position and a second position. Specifically, the guide groove 71 can be formed by opening a groove in the side wall of the housing 1, or by providing opposing guide blocks 72 on the side wall of the housing 1, with the guide groove 71 formed between the two guide blocks 72. This disclosure does not limit the formation method. The extending direction of the guide groove 71 can be parallel to the traveling direction of the floor brush, or intersect with the traveling direction of the floor brush but have a parallel component (i.e., the two directions are not perpendicular to each other). The fact that the extending direction of the guide groove 71 is at least partially parallel to the traveling direction of the floor brush allows the sealing member 5 to move along the guide groove 71 by the friction between the sealing member 5 and the target side surface when the floor brush is traveling. The guide groove 71 is designed to provide precise guidance and stable support for the reciprocating movement of the sealing component 5 between the first and second positions.

[0061] Please refer to Figure 5 The sealing element 5 can be configured as a plate, which moves closer to or further away from the second air inlet 41 to open or close the second air inlet 41. Alternatively, the sealing element 5 can be configured as a plate with a specific opening. When the sealing element 5 is in the first position, the plate can close the second air inlet 41; when the sealing element 5 is in the second position, the opening of the plate exposes the second air inlet 41, thereby opening the second air inlet 41 accordingly. This disclosure does not limit its specific structural form.

[0062] Please refer to Figure 5 The sealing component 5 is equipped with bristles 8 that can contact the target side surface. The bristles 8 serve several purposes: firstly, as the part that contacts the target side surface, their flexibility effectively buffers the impact force upon contact, preventing scratches or damage to the wall or baseboard. Secondly, during cleaning, the bristles 8 can penetrate the fine irregularities of the baseboard surface, sweeping away dust accumulated in its crevices and guiding it to the vicinity of the second air inlet 41, where it works in conjunction with negative pressure suction to achieve deep cleaning. Furthermore, the bristles 8 also increase the friction with the target side surface, ensuring that the sealing component 5 can smoothly open the second air inlet 41.

[0063] Please refer to Figure 5 Specifically, the bristles 8 are evenly distributed on the side of the sealing member 5 facing away from the housing 1; and / or, the bristles 8 are flexible bristles; and / or, the length of the bristles 8 is 5mm-10mm. By optimizing the arrangement, material, and length of the bristles 8, the cleaning effect and user experience can be further improved.

[0064] Please refer to Figure 6In one optional embodiment, the floor brush may include two second dust collection channels 4, and the second air inlets 41 of the two second dust collection channels 4 are formed on two opposite sidewalls of the housing 1. Furthermore, a sealing member 5 corresponding to the second air inlet 41 may also be provided. By providing two second dust collection channels 4, the floor brush can meet the cleaning needs of the left or right baseboard. Therefore, regardless of which side of the wall the floor brush travels along, the corresponding second air inlet 41 can be opened and cleaned with the cooperation of the sealing member 5. This not only expands the product's applicable scenarios but also avoids the inconvenience of users needing to repeatedly adjust the direction of the floor brush, further improving cleaning efficiency and convenience.

[0065] Please combine Figures 1 to 5 The floor brush disclosed herein includes two cleaning modes: normal floor cleaning mode and baseboard cleaning mode.

[0066] When the floor brush is not close to the baseboard, it operates in normal floor cleaning mode. At this time, the elastic element 6 is in its naturally extended state, and the sealing element 5 is positioned in the first position under the elastic force of the elastic element 6, closing the second air inlet 41 and isolating the second dust collection channel 4 from the outside of the housing 1. After the floor brush is activated, the negative pressure provided by the negative pressure source creates a stable negative pressure environment only within the first dust collection channel 2, thus ensuring the dust removal efficiency of the first dust collection channel 2 on the floor, and its negative pressure vacuum degree meets the floor cleaning standards of mainstream household vacuum cleaners.

[0067] When the user pushes the floor brush close to the baseboard, the brush is in baseboard cleaning mode. At this time, as the user moves the brush, the bristles 8 contact the baseboard surface, and the bristles 8 experience a backward reaction force from the baseboard. This reaction force is transmitted through the bristles 8 to the sealing member 5. When the reaction force exceeds the forward elastic force of the elastic member 6, the sealing member 5 overcomes the elastic force and slides backward until it reaches the second position, opening the second air inlet 41 and connecting the second dust collection channel 4 to the outside of the housing 1. After the floor brush is activated, the negative pressure provided by the negative pressure source can also create a negative pressure environment within the second dust collection channel 4 to clean the baseboard. Simultaneously, as the bristles 8 move relative to the baseboard, they loosen and sweep away surface dust, hair, and other dirt. The loosened dirt, under the action of negative pressure, enters the second dust collection channel 4 through the second air inlet 41 and is ultimately collected and processed.

[0068] Please refer to Figure 1 In one embodiment of this disclosure, a cleaning device is also provided, including the aforementioned floor brush. It is understood that the cleaning device equipped with the aforementioned floor brush, due to integrating all the advantages of the floor brush, possesses the ability to automatically adapt to cleaning scenarios involving floors and baseboards, achieving deep cleaning of the entire house without dead angles, effectively improving cleaning efficiency and optimizing the user experience.

[0069] In summary, the floor brush and cleaning device disclosed herein have at least the following significant beneficial effects:

[0070] (1) Achieve efficient cleaning of baseboards and thorough collection of dirt: Through the synergistic effect of the second air inlet 41 and the brush bristles 8, it can not only clean dirt close to the target side areas such as baseboards, but also directly suck the dirt into the vacuum cleaner, avoiding the problem of incomplete "adhesive" cleaning of existing scouring pad solutions.

[0071] (2) Avoid secondary pollution: Dirt is collected and treated directly through the second dust collection channel 4 without the need for external cleaning components (such as scouring pads), which completely solves the defect of dirt carriers contaminating clean areas in the existing solution and ensures the cleanliness of the cleaning process.

[0072] (3) Adaptive scene switching and convenient operation: The second air inlet 41 is automatically opened and closed by balancing the friction between the sealing part 5 and the wall surface and the elasticity of the elastic part 6. Users do not need to manually switch the switch or adjust the floor brush structure, which conforms to the user's regular cleaning operation habits and reduces the threshold of use.

[0073] (4) Ensure the dust removal efficiency of the ground under normal conditions: Under normal conditions, the second air inlet 41 is completely blocked to ensure that the negative pressure vacuum of the first air inlet 21 at the bottom of the floor brush is not affected, thus avoiding the problem of reduced dust removal capacity caused by negative pressure dispersion, and balancing the skirting board cleaning function and the regular cleaning performance.

[0074] (5) Simple structure and strong compatibility: The core components only add a second dust collection channel 4, elastic part 6 and sealing part 5. The overall structure is compact and can be adapted to the installation size of the floor brush of existing cleaning equipment, which is convenient for mass production and upgrading of old products.
