Technical Field
[0001] This utility model belongs to the field of cleaning technology, and more specifically, it relates to a cleaning device. Background Technology
[0002] In the field of cleaning appliances, floor scrubbers typically rely on rotating rollers combined with front and rear squeegees to clean stains and water from floors. However, existing floor scrubbers generally have a significant drawback when they stop working: the front and rear squeegees tend to leave two sections of water marks on the floor, which not only affects the cleaning effect but also reduces the user experience.
[0003] How to effectively remove water stains left on the front and rear squeegees after the floor scrubber has stopped, while avoiding wear and tear on the roller brush during operation, has become an urgent technical challenge. Utility Model Content
[0004] The purpose of this utility model embodiment is to provide a cleaning device that solves the technical problem in the related art of being unable to remove water marks left after the floor scrubber stops, while avoiding wear and tear caused by the roller brush during operation.
[0005] To achieve the above objectives, according to a first aspect of the present invention, a cleaning device is provided, the cleaning device comprising:
[0006] body;
[0007] A floor brush is connected to the lower end of the machine body. The floor brush is equipped with a movable first scraper, a second scraper, and a roller brush. The first scraper is located on the front side of the roller brush, and the second scraper is located on the rear side of the roller brush.
[0008] The floor brush is equipped with a water distributor, which is used to supply water to the roller brush to keep the roller brush wet when the cleaning equipment stops cleaning and moves to deal with water stains. When dealing with water stains, the water supply of the water distributor is less than the normal water supply during the cleaning operation.
[0009] In some implementation methods,
[0010] Floor brushes also include scraper strips;
[0011] The scraper bar, which comes into contact with the bristles of the roller brush, is used to squeeze out water from the bristles when the roller brush rotates forward and backward, and to comb the bristles when the roller brush rotates backward.
[0012] In some implementations, the water supply of the distributor when dealing with water stains includes:
[0013] When the roller brush rotates forward, the water distributor supplies water to the roller brush at the first water supply rate; when the roller brush rotates in reverse, the water distributor supplies water to the roller brush at the second water supply rate. The first water supply rate and the second water supply rate may be the same or different.
[0014] In some implementations, a water distributor is used to continuously supply water to the roller brush while the cleaning equipment stops cleaning and moves to handle water stains, or to supply water to the roller brush at predetermined time intervals.
[0015] In some implementations, a suction device is also installed inside the machine body to maintain a suction state during the cleaning process, so that the roller brush can absorb the water stains on the surface to be cleaned.
[0016] In some implementations, the cleaning equipment also includes:
[0017] The controller, connected to the first and second scrapers, is configured to execute:
[0018] In response to receiving a stop signal indicating to stop the cleaning operation, if the first scraper is in a first position in contact with the surface to be cleaned, the first scraper is controlled to be raised to a second position so that the first scraper is no longer in contact with the surface to be cleaned;
[0019] Control the cleaning equipment to move in the first direction, and stop moving when the moving distance reaches at least the first distance;
[0020] When the moving distance reaches the first distance, the cleaning equipment is controlled to move in the second direction, and stops moving when the moving distance reaches at least the second distance. The first direction and the second direction are opposite directions.
[0021] In some implementations, the cleaning equipment also includes:
[0022] As the cleaning equipment moves in the first direction, the roller brush rotates clockwise; as the cleaning equipment moves in the second direction, the roller brush rotates counterclockwise; or...
[0023] As the cleaning equipment moves in the first direction, the roller brush rotates in reverse; as the cleaning equipment moves in the second direction, the roller brush rotates in the forward direction.
[0024] In some implementations, the cleaning equipment also includes:
[0025] A water pump, connected to a distributor, is used to supply water to the distributor.
[0026] In some implementations, the cleaning equipment also includes:
[0027] The assist wheel is located on the floor brush and behind the roller brush.
[0028] In some implementations, the power-assisted wheel is also connected to a controller in the cleaning equipment, which controls the cleaning equipment to move in the first direction and is configured to perform:
[0029] Control the roller brush and / or booster wheel to rotate in a first direction so that the cleaning equipment moves in the first direction.
[0030] In some implementations, the power-assisted wheel is also connected to a controller in the cleaning equipment, which controls the cleaning equipment to move in a second direction and is configured to perform:
[0031] Control the roller brush and / or booster wheel to rotate in the second direction so that the cleaning equipment moves in the second direction.
[0032] This embodiment of the cleaning equipment provides a method where, during the cleaning process after the equipment stops cleaning and moves to handle water stains, a water distributor supplies water to the roller brush to keep it moist. The water supply during water stain handling is less than the normal water supply during cleaning. This works in conjunction with the movable first and second scrapers on the floor brush, as well as the coordinated operation of the machine body and the roller brush. On one hand, this effectively wipes away water stains after the cleaning equipment stops, solving the problem of water stains left on the floor after traditional floor scrubbers stop, which affects user experience. On the other hand, because the roller brush rotates in a moist state, the friction is significantly reduced, thus preventing abnormal increases in the roller brush gearbox current caused by excessive friction, extending the roller brush's lifespan. This improves cleaning effectiveness while enhancing the reliability and durability of the cleaning equipment, providing users with a higher quality, more efficient, and more economical cleaning experience.

[0041] As described in the background section, currently, in the field of cleaning appliances, floor scrubbers typically rely on the rotation of a roller brush combined with the wiping action of front and rear squeegees to clean stains and water from the floor. However, existing floor scrubbers generally have a significant drawback when they stop working: the front and rear squeegees tend to leave two sections of water marks on the floor, which not only affects the cleaning effect but also reduces the user experience.
[0042] In related technologies, after the floor scrubber stops working, it removes water stains by moving forward and backward. However, the water pump is stopped during this process, and the surface of the roller brush lacks moisture. As the roller brush reverses and changes direction, the friction increases and generates a large torque, which causes the current in the roller brush gearbox to rise sharply. This accelerates the wear of the gears inside the gearbox and the motor, significantly shortening the service life of the roller brush and gearbox. At the same time, the roller brush repeatedly scrapes the ground in a water-deficient state, which also aggravates its own wear.
[0043] How to effectively remove water stains left on the front and rear squeegees after the floor scrubber has stopped, while avoiding wear and tear on the roller brush during operation, has become an urgent technical challenge.
[0044] See Figure 1As shown, in order to solve the above problems, according to an embodiment of the present invention, a cleaning device is provided, the cleaning device comprising:
[0045] Fuselage 10.
[0046] A floor brush 11 is connected to the lower end of the body 10. The floor brush 11 is equipped with a movable first scraper 12, a second scraper 13 and a roller brush 14. The first scraper 12 is located on the front side of the roller brush 14 and the second scraper 13 is located on the rear side of the roller brush 14.
[0047] The floor brush 11 is equipped with a water distributor 111. The water distributor 111 is used to supply water to the roller brush 14 to keep the roller brush 14 wet when the cleaning equipment stops cleaning and moves to deal with water stains. The water supply of the water distributor 111 is less than the normal water supply during the cleaning operation when dealing with water stains.
[0048] In some embodiments, the cleaning equipment can be any type of floor scrubber, such as a cordless floor scrubber, a handheld floor scrubber, a household floor scrubber, an industrial floor scrubber, or a smart floor scrubber.
[0049] In some embodiments, taking the cleaning equipment described above as a floor scrubber as an example, the floor scrubber is equipped with a liftable front squeegee (first squeegee), a rear squeegee (second squeegee), and a roller brush. For example, the roller brush can be made of high-density pile material.
[0050] In some embodiments, the body is the main support structure of the cleaning equipment, and the lower end of the body is firmly connected to the floor brush, providing a foundation for the operation of the various components of the floor brush. The floor brush, as the core cleaning component, specifically includes a movable first scraper located at the front of the roller brush. During normal operation of the cleaning equipment, this first scraper can initially remove larger particles of dirt and accumulated water from the floor, reducing the burden on the subsequent cleaning work of the roller brush. A second scraper is located at the rear of the roller brush, and its main function is to further scrape away residual water stains and fine dirt from the floor after the roller brush has cleaned, ensuring the integrity of the cleaning effect.
[0051] In some embodiments, the roller brush is the key component for cleaning the floor. The surface of the roller brush is usually covered with soft bristles that have good adsorption and wiping ability. Driven by a motor or other drive device, it rotates and, together with cleaning agent and water, performs a comprehensive wiping and cleaning of the floor.
[0052] In some embodiments, the water distributor installed inside the floor brush plays an indispensable regulatory role throughout the operation of the cleaning equipment. When the cleaning equipment is in normal cleaning operation, the water distributor evenly delivers clean water or prepared cleaning solution to the roller brush according to the preset normal water supply, keeping the roller brush sufficiently moist to meet the needs of efficiently cleaning various stubborn stains on the floor. After the cleaning equipment completes its cleaning task and stops cleaning operation, when faced with the situation of dealing with residual water stains on the scraper, the working mode of the water distributor changes.
[0053] At this time, the water supply of the distributor is controlled to be lower than the level during normal cleaning operations. The reason for this setting is that an appropriate water supply can ensure that the bristles remain moist during the reverse and movement of the roller brush, thereby reducing the friction between the roller brush and the ground as well as its internal rotating parts. This avoids abnormal increases in the current of the roller brush gearbox due to excessive friction, and thus effectively extends the service life of the roller brush and related transmission components. On the other hand, providing a smaller water supply when dealing with residual water stains can prevent secondary water stains or adverse effects on other electronic components and mechanical structures inside the cleaning equipment due to excessive water. At the same time, it can also save water and improve energy efficiency.
[0054] For example, taking a floor scrubber as an example of cleaning equipment, in actual application scenarios, after the floor scrubber has finished cleaning hard floors such as living rooms in homes, in response to the stop signal, the controller controls the water distributor to switch to water stain mode, supplying water to the roller brush for several seconds at a rate of about one-third less than during normal cleaning. This helps the roller brush easily wipe away the water stains remaining on the first and second scrapers during its movement, achieving efficient and precise treatment of water stains on the floor and significantly improving the user experience.
[0055] This embodiment of the cleaning equipment provides a method where, during the cleaning process after the equipment stops cleaning and moves to handle water stains, a water distributor supplies water to the roller brush to keep it moist. The water supply during water stain handling is less than the normal water supply during cleaning. This works in conjunction with the movable first and second scrapers on the floor brush, as well as the coordinated operation of the machine body and the roller brush. On one hand, this effectively wipes away water stains after the cleaning equipment stops, solving the problem of water stains left on the floor after traditional floor scrubbers stop, which affects user experience. On the other hand, because the roller brush rotates in a moist state, the friction is significantly reduced, thus preventing abnormal increases in the roller brush gearbox current caused by excessive friction, extending the roller brush's lifespan. This improves cleaning effectiveness while enhancing the reliability and durability of the cleaning equipment, providing users with a higher quality, more efficient, and more economical cleaning experience.
[0056] In some implementations, such as Figure 2As shown, the floor brush 11 also includes: a scraper 112; the scraper 112 is in contact with the bristles of the roller brush 40 and is used to squeeze water out of the bristles of the roller brush 40 when the roller brush 40 rotates forward and backward, respectively, and to comb the bristles of the roller brush 40 when the roller brush 40 rotates backward.
[0057] In some embodiments, in the practical application of this cleaning equipment, the scraper and roller brush inside the floor brush work together to greatly improve the cleaning effect and equipment performance. When the cleaning equipment performs normal cleaning operations, or when the cleaning equipment stops normal cleaning operations and the roller brush rotates forward to perform floor cleaning or water stain removal tasks, the scraper closely adheres to the bristles of the roller brush, and the contact between the scraper and the bristles forms a specific compression structure. At this time, the scraper effectively compresses the wastewater and stains adsorbed by the roller brush during the cleaning process, causing the wastewater to be squeezed out along the rotation direction of the roller brush and flow into the wastewater recycling channel inside the floor brush, preventing the wastewater from being brought back to the ground and causing secondary pollution.
[0058] In some embodiments, when the cleaning device is handling water stains, the scraper's role is further expanded as the roller brush reverses its direction. It not only squeezes water out of the brush bristles again, removing any remaining moisture to prevent excess water from dripping during subsequent wiping and affecting cleaning effectiveness, but also acts as a combing tool. Using its specific shape and structure, the scraper combs the fluffy and potentially tangled bristles in the direction the roller brush reverses. The combed bristles regain their neat and orderly state, allowing for better absorption and wiping of residual water stains, enhancing the roller brush's cleaning ability, and reducing wear caused by tangling and knotting, thus extending the roller brush's lifespan.
[0059] In some embodiments, for example, when dealing with water stains after cleaning oil stains on a kitchen floor, the squeegee can squeeze out the water with oil stains and comb the bristles stuck to the oil stains during the reversal of the roller brush, so that the roller brush can complete the water stain cleaning work in the best condition, ensuring the efficient operation of the cleaning equipment and the cleaning quality.
[0060] In some implementations, the water supply of the distributor when dealing with water stains includes:
[0061] When the roller brush rotates forward, the water distributor supplies water to the roller brush at the first water supply rate; when the roller brush rotates in reverse, the water distributor supplies water to the roller brush at the second water supply rate. The first water supply rate and the second water supply rate may be the same or different.
[0062] In some embodiments, during the cleaning process, the water supply from the distributor changes according to the direction of the roller brush. The distributor has two water supply modes: a first water supply when the roller brush rotates clockwise and a second water supply when the roller brush rotates counterclockwise. The first and second water supply rates can be differentiated according to actual cleaning needs.
[0063] For example, when the cleaning equipment first starts moving to treat water stains and the roller brush rotates to wipe the first section of water marks, the water distributor can be set to provide the initial water supply. If there are many water stains remaining on the floor, the initial water supply can be appropriately increased to ensure the roller brush is adequately moistened, thus quickly diluting and softening stubborn water stains and improving cleaning efficiency. If there are few water stains remaining on the floor, the initial water supply can be reduced to avoid wasting water resources and leaving too much water behind.
[0064] As the roller brush continues to clean water stains and reverses to wipe the second section of watermarks, the water distributor provides a second water supply. If the roller brush remains highly moist after the first section of watermarks is cleaned, and the second section of water stains is relatively small, the second water supply can be set to be less than the first water supply to precisely control the water volume, maintain the appropriate moisture level of the roller brush, and reduce the rotational resistance caused by excessive water. Conversely, if the second section of water stains is larger or more stubborn, the second water supply can be the same as the first water supply, or even appropriately increased, to ensure that the roller brush has enough water for cleaning.
[0065] Of course, depending on the cleaning scenario and equipment operating conditions, the first and second water supply volumes can also be set to the same value. For example, on a relatively uniform cleaning surface, where water stains are distributed and their stubbornness is similar, to simplify the control process and maintain consistency in cleaning intensity, the water supply volume of the distributor can be set to the same value when the roller brush is rotating forward and backward to handle water stains. This allows the cleaning equipment to stably output cleaning power, efficiently complete the water stain removal work, reduce the complexity of control parameters, and improve the stability and reliability of the cleaning equipment operation.
[0066] Furthermore, by using a water distributor to supply water to the roller brush during forward and reverse rotation, the friction is significantly reduced when the roller brush is reversed or changed direction in a wet state. As a result, this embodiment of the invention can avoid abnormal increase in the roller brush gearbox current caused by excessive friction, effectively reduce the high torque generated when the roller brush reverses, and greatly extend the service life of core components such as the roller brush and gearbox.
[0067] In some implementations, a water distributor is used to continuously supply water to the roller brush while the cleaning equipment stops cleaning and moves to handle water stains, or to supply water to the roller brush at predetermined time intervals.
[0068] When the cleaning equipment stops cleaning and enters the water stain treatment stage, the variety of water supply modes of the water distributor provides flexible options for optimizing cleaning effect and equipment performance.
[0069] In some embodiments, when the water distributor continuously supplies water to the roller brush, it continuously delivers water to the roller brush from the moment the cleaning equipment begins to move and treat water stains, ensuring that the roller brush remains consistently moist. This water supply mode is particularly suitable for scenarios with a large amount of water stains and complex floor residue, such as the large amount of mixed water stains remaining after cleaning a kitchen oily floor. Continuous water supply ensures that the roller brush always has sufficient moisture to dissolve and absorb stains during repeated wiping, preventing a decrease in the roller brush's cleaning ability due to insufficient moisture, and effectively ensuring the continuity and thoroughness of cleaning.
[0070] In some embodiments, under the predetermined time interval water supply mode, the water distributor periodically supplies water to the roller brush according to a pre-set time rhythm. For example, it is set to supply water once every 5 seconds, with each supply lasting 1 second. This mode can precisely control the water supply according to actual needs, ensuring that the roller brush is wet enough to meet cleaning requirements while maximizing water conservation. In scenarios with less water stains and relatively clean floors, such as cleaning water stains after cleaning a bedroom floor, the predetermined time interval water supply can maintain the necessary moisture level of the roller brush, reducing the resistance of the roller brush's reverse rotation, while also preventing excessive water supply that could cause secondary wetting or water accumulation on the floor, achieving the dual goals of efficient cleaning and energy saving. Through the flexible switching and application of these two water supply modes, the water distributor can adapt to different cleaning scenarios, improving the performance of cleaning equipment and the user experience.
[0071] In some implementations, a suction device is also installed inside the machine body to maintain a suction state during the cleaning process, so that the roller brush can absorb the water stains on the surface to be cleaned.
[0072] During the water stain removal process of the cleaning equipment, the suction device installed inside the machine can be a centrifugal fan suction device, a turbine suction device, or a vacuum negative pressure suction device. When the cleaning equipment stops normal cleaning operation and begins to move to treat the two sections of water stains remaining on the front and rear scrapers, the suction device remains operational. As the roller brush moves with the cleaning equipment, wiping and absorbing water stains on the floor, the suction device generates a continuous and stable suction force to quickly draw the water absorbed by the roller brush into the wastewater recovery chamber inside the cleaning equipment. This prevents the roller brush from becoming too wet and heavy due to excessive water absorption, which would affect its rotation efficiency and cleaning effect.
[0073] For example, when cleaning water stains on a living room tile floor, the roller brush rubs against the floor as it moves, absorbing residual water between the bristles. At this point, the suction device generates suction through the internal pipes of the brush, quickly drawing away the water from the roller brush. This ensures the brush maintains a suitable level of moisture and absorption capacity, allowing for continuous and effective wiping until both watermarks are completely removed. Simultaneously, the suction device prevents water from dripping back onto already cleaned areas during the cleaning process, ensuring efficient and clean water removal and significantly improving the user's cleaning experience.
[0074] In some implementations, the cleaning equipment also includes:
[0075] The controller, connected to the first and second scrapers, is configured to execute:
[0076] In response to receiving a stop signal indicating to stop the cleaning operation, if the first scraper is in a first position in contact with the surface to be cleaned, the first scraper is controlled to rise to a second position so that the first scraper is no longer in contact with the surface to be cleaned; the cleaning device is controlled to move in a first direction and stop moving when the moving distance reaches at least a first distance; when the moving distance reaches the first distance, the cleaning device is controlled to move in a second direction and stop moving when the moving distance reaches at least a second distance, wherein the first direction and the second direction are opposite directions.
[0077] In some embodiments, the controller coordinates the movement of the scraper and the cleaning device in the cleaning equipment to improve water stain removal efficiency. When the user issues a stop command via the control panel or remote control, the controller receives the stop signal and immediately detects the current position of the first scraper. If the first scraper is detected to be in the first position in contact with the surface to be cleaned (e.g., ...), the controller will detect the position of the first scraper. Figure 1 As shown), the controller sends a control signal to the drive device of the first scraper, such as a motor or hydraulic system, to drive the first scraper to rise to the second position (as shown). Figure 2 As shown), the first scraper is removed from contact with the surface to be cleaned (e.g., lifted 5-15mm off the ground) to avoid scratching the ground or leaving scratches during subsequent equipment movement.
[0078] Subsequently, the controller sends a command to the cleaning equipment's drive system, controlling the cleaning equipment to move in the first direction away from the user. During this movement, the roller brush continues to rotate and, in conjunction with the water distributor, supplies an appropriate amount of water to wipe away the first section of water marks remaining on the front scraper. The controller monitors the moving distance of the cleaning equipment in real time through a built-in distance sensor or encoder. When the moving distance reaches at least the preset first distance, it indicates that the first section of water marks has been effectively cleaned, and the controller then controls the cleaning equipment to stop moving.
[0079] Next, the controller sends another command to the cleaning equipment's drive system, changing the cleaning equipment's direction of movement so that it moves towards the user in a second direction. During this process, the roller brush reverses and continues to absorb and clean the second section of water marks remaining on the rear scraper. Similarly, the controller resumes continuous monitoring of the cleaning equipment's movement distance. When the movement distance reaches at least the preset second distance, it determines that the second section of water marks has been cleaned, controls the cleaning equipment to stop moving, and completes the water stain removal process.
[0080] It should be understood that the aforementioned first and second distances are not specifically limited, and can be set or modified according to the specific application scenario of the cleaning equipment. For example, in a home living room cleaning scenario, the first distance can be set to 50-70 cm, and the second distance can be set to 40-60 cm. There are no specific limitations. Through precise position control, the controller ensures that the cleaning equipment can efficiently and thoroughly clean the two sections of water marks left behind when the cleaning equipment stops, providing users with a high-quality cleaning experience.
[0081] In some implementations, the cleaning equipment also includes:
[0082] As the cleaning equipment moves in the first direction, the roller brush rotates clockwise; as the cleaning equipment moves in the second direction, the roller brush rotates counterclockwise. Alternatively, as the cleaning equipment moves in the first direction, the roller brush rotates counterclockwise; as the cleaning equipment moves in the second direction, the roller brush rotates clockwise.
[0083] During the process of cleaning equipment treating water stains, there are two coordinated control modes for the rotation direction of the roller brush and the movement direction of the cleaning equipment, in order to adapt to different cleaning scenarios and user needs.
[0084] In some embodiments, in the first collaborative mode, when the cleaning device moves in a first direction away from the user, the roller brush rotates forward. At this time, the brush bristles contact the ground in the designed conventional cleaning direction. With the appropriate water supply from the water distributor, the first section of water residue left by the front scraper can be efficiently absorbed into the bristles. Simultaneously, the scraper inside the floor brush squeezes water from the rotating roller brush, expelling the wastewater absorbed by the bristles and guiding it to the wastewater recycling channel, ensuring that the roller brush always maintains good adsorption capacity. When the cleaning device moves in a second direction closer to the user, the roller brush reverses. The reversed roller brush can change the contact angle and friction direction between the bristles and the ground, more effectively cleaning the second section of water residue left by the rear scraper. Moreover, the scraper combs the bristles when the roller brush reverses, restoring the fluffy bristles to neatness, further enhancing the roller brush's absorption and wiping effect on water stains.
[0085] In some embodiments, the second collaborative mode involves the roller brush reversing when the cleaning device moves in the first direction and rotating forward when moving in the second direction. This mode is suitable for certain special cleaning scenarios, such as when the water stains on the floor are unevenly distributed, or when the water stains left by the rear squeegee are more stubborn. When the cleaning device moves away from the user, the special wiping effect produced by the roller brush reversing can better handle stubborn water stains; while when moving closer to the user, the roller brush rotating forward utilizes its regular cleaning advantages to thoroughly clean the water stains left by the front squeegee.
[0086] Through these two flexible collaborative control modes, the cleaning equipment can optimize the coordination between the rotation direction of the roller brush and the movement direction of the cleaning equipment according to actual cleaning needs, thereby maximizing the efficiency of water stain removal and cleaning effect, and providing users with a more convenient and efficient cleaning experience.
[0087] In some implementations, the cleaning equipment also includes:
[0088] A water pump, connected to a distributor, is used to supply water to the distributor.
[0089] In the water supply system of the cleaning equipment, the water pump and the distributor work together. The water pump is closely connected to the distributor through pipes, forming a complete fluid delivery network. When the cleaning equipment is in normal cleaning mode, the controller sends a working command to the water pump according to preset cleaning parameters. After the water pump starts, it generates pressure and delivers water from the clean water tank to the distributor. The distributor sprays water evenly onto the roller brush according to a predetermined distribution strategy, ensuring that the roller brush remains moist during high-speed rotation to enhance its ability to adsorb and clean stains on the floor.
[0090] When the cleaning equipment stops cleaning and enters the water stain treatment stage, the water pump's operating mode is dynamically adjusted. When the roller brush rotates forward to treat the first stage of water stains, the controller adjusts the water pump's power or running time to ensure the distributor supplies water to the roller brush at the initial water volume. For example, if a large amount of residual water stains is detected, the water pump will increase its power, increasing the water supply per unit time to ensure the roller brush has sufficient water to soften and dilute stubborn stains. When the roller brush rotates in reverse to treat the second stage of water stains, the water pump precisely controls the water supply according to preset second water volume parameters. At this time, if the second stage of water stains is relatively small, the water pump will reduce its power or shorten the water supply time to avoid excessive water leaving residual stains on the ground.
[0091] In some embodiments, the operating state of the water pump is also closely related to the moving direction of the cleaning equipment and the rotation state of the roller brush. When the cleaning equipment moves in the first direction, the water pump provides a stable water flow to the distributor in a forward rotation water supply mode; while when the equipment moves in the opposite second direction, the water pump adjusts the water supply pressure and flow rate according to the roller brush's reverse rotation requirement, ensuring that the brush bristles still receive uniform moisture during the roller brush's reverse rotation, thus improving the water stain removal effect. Through the precise coordination of the water pump and the distributor, the water demand of different cleaning stages can be met, and water resources can be used efficiently, bringing users a more convenient and environmentally friendly cleaning experience.
[0092] In some implementations, such as Figure 3 As shown, the cleaning equipment also includes:
[0093] The assist wheel 21 is mounted on the floor brush 11 and is located on the rear side of the roller brush 14.
[0094] In some embodiments, the assist wheel is mounted on the floor brush and located behind the roller brush. It should be understood that the position of the assist wheel is designed with the center of gravity distribution and biomechanical principles of the cleaning equipment in mind. During normal cleaning operation, the assist wheel contacts the ground and provides forward or backward assist power to the cleaning equipment via a built-in drive device or a transmission mechanism linked to the roller brush. When the user pushes the cleaning equipment forward, the assist wheel automatically senses the direction and force of movement and outputs corresponding driving force, reducing the user's pushing burden. This is especially beneficial when cleaning large areas of flooring, significantly reducing labor costs.
[0095] In some embodiments, the assist wheel also plays a crucial role when the cleaning equipment stops cleaning and enters the water stain removal stage. When the cleaning equipment moves in a first or second direction to clean residual water stains on the front and rear scrapers, the assist wheel closely coordinates with the rotation of the roller brush and the movement of the cleaning equipment, ensuring smooth and stable movement through precise power output. For example, when the roller brush reverses to clean water stains on the rear scraper, the assist wheel can adjust its speed and torque in real time according to the movement of the cleaning equipment, preventing the cleaning equipment from jamming or becoming difficult to move due to the resistance generated by the roller brush reversal. Simultaneously, the assist wheel effectively enhances the stability of the cleaning equipment during movement, preventing tilting or wobbling caused by uneven ground, ensuring good contact between the roller brush and the ground, thus completing the water stain removal work more efficiently and comprehensively improving the user experience.
[0096] In some implementations, the assist wheel is also connected to a controller in the cleaning equipment, which controls the cleaning equipment to move in a first direction and is configured to perform: control the roller brush and / or the assist wheel to rotate in the first direction so that the cleaning equipment moves in the first direction.
[0097] In some embodiments, when the controller receives an instruction to stop the cleaning operation and handle water stains, it flexibly adjusts the rotation state of the roller brush and the assist wheel according to the actual working conditions while controlling the cleaning equipment to move away from the user. In some cleaning scenarios, the controller can independently control the assist wheel to rotate in a first direction (such as the direction away from the user), for example, clockwise. The friction between the assist wheel and the ground generates a forward thrust, enabling the cleaning equipment to move smoothly in the first direction. This mode is suitable for areas with relatively flat ground and evenly distributed water stains, fully utilizing the driving advantage of the assist wheel and reducing energy consumption.
[0098] In other embodiments, in areas with high ground resistance or stubborn water stains, the controller can simultaneously activate the roller brush and the booster wheel. The roller brush rotates in a first direction, providing additional forward momentum through the friction between the bristles and the ground, while simultaneously performing initial cleaning of residual water stains on the ground; the booster wheel rotates synchronously, forming a coordinated drive with the roller brush to ensure that the cleaning equipment has sufficient power to overcome resistance and successfully complete the first stage of water stain removal.
[0099] For example, in areas with heavy oil stains, such as kitchens, where floor friction is high, the controller can prioritize driving both the roller brush and the assist wheel simultaneously. The rotation of the roller brush softens stubborn oil stains and provides auxiliary power for the device to move forward; the assist wheel, through precise torque output, ensures that the cleaning equipment moves stably on oily floors, preventing slippage.
[0100] The cleaning equipment provided by this utility model adopts a flexible dual-drive control strategy, which allows the cleaning equipment to adapt to different cleaning scenarios and efficiently complete water stain removal tasks, providing users with a more intelligent and convenient cleaning experience.
[0101] In some implementations, the assist wheel is also connected to a controller in the cleaning equipment, which controls the cleaning equipment to move in a second direction and is configured to perform: control the roller brush and / or the assist wheel to rotate in the second direction so that the cleaning equipment moves in the second direction.
[0102] In some embodiments, when the controller receives a command to stop the cleaning operation and handle water stains, it flexibly adjusts the rotation state of the roller brush and the assist wheel according to the actual working conditions while controlling the cleaning equipment to move towards the user. In some cleaning scenarios, the controller can independently control the assist wheel to rotate in a second direction (such as the direction closer to the user), for example, counterclockwise. The friction between the assist wheel and the ground generates a backward thrust, allowing the cleaning equipment to move smoothly in the second direction. This mode is suitable for areas with relatively flat ground and evenly distributed water stains, fully utilizing the driving advantage of the assist wheel and reducing energy consumption.
[0103] In some embodiments, in areas with high ground resistance or stubborn water stains, the controller activates both the roller brush and the booster wheel simultaneously. The roller brush rotates in a second direction, providing additional backward momentum through the friction between the bristles and the ground, while simultaneously performing deep cleaning of residual water stains; the booster wheel rotates in reverse simultaneously, working in synergy with the roller brush to ensure that the cleaning equipment overcomes resistance and successfully completes the second stage of water stain removal.
[0104] For example, in areas prone to dust accumulation, such as the edges of living room carpets, where floor friction is high, the controller prioritizes simultaneously driving the roller brush and the assist wheels. The reverse rotation of the roller brush effectively absorbs stubborn dust and provides auxiliary power for the cleaning equipment to move backward; the assist wheels, through precise torque output, ensure stable movement of the cleaning equipment on complex terrains such as carpet edges, preventing jamming.
[0105] The cleaning equipment provided by this utility model adopts a flexible dual-drive control strategy, which allows the cleaning equipment to adapt to different cleaning scenarios and efficiently complete water stain removal tasks, providing users with a more intelligent and convenient cleaning experience.
