Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a cleaning roller brush, a floor scrubber, and a control method thereof. Background Technology

[0002] As the core cleaning component of a floor scrubber, the roller brush primarily relies on high-speed rotation to generate friction with the floor, using water or cleaning solution to wipe away stains. It is a key structure ensuring the cleaning performance of the equipment. Currently, the roller brush cleaning method has a limited scope of application, only suitable for cleaning regular dust and light stains. For stubborn stains with strong adhesion and high penetration, such as dried coffee stains, stubborn oil stains, chewing gum residue, and hardened pet stains, it suffers from low cleaning efficiency and incomplete cleaning.

[0003] To overcome the limitations of cleaning stubborn stains, relevant technologies mainly employ three auxiliary cleaning solutions. The first is the repeated friction cleaning solution, which increases the frequency of friction on the stained area by extending the localized working time of the roller brush or relying on the user to manually push and pull the equipment repeatedly. This method not only significantly increases the user's workload but also results in inconsistent manual operation and unstable cleaning effects. The second is the chemical-assisted cleaning solution, which softens stains through the chemical decomposition of a specialized cleaning solution by adding a liquid storage and spray structure. This requires continuous consumption of cleaning consumables, leading to higher costs, and its softening and peeling effect on some stubborn, dried stains is limited. The third is the thermal-assisted cleaning solution, which integrates a heating module to heat the water, accelerating stain dissolution through heat. This solution requires supporting heating, temperature control, and leakage protection structures, significantly increasing equipment complexity and production costs. It also suffers from drawbacks such as water temperature decay, high energy consumption, and unstable cleaning effects.

[0004] Existing cleaning solutions do not alter the motion characteristics of the roller brush. During operation, the roller brush only generates shear friction parallel to the ground, lacking the impact and loosening force perpendicular to the ground. This makes it ineffective at removing dried, strongly adhered, and stubborn stains, failing to address the fundamental problem of cleaning stubborn stains at the mechanical motion level of the roller brush. Therefore, there is an urgent need to develop a simple roller brush technology for floor scrubbers that can improve the cleaning ability of stubborn stains by optimizing its mechanical motion characteristics. Summary of the Invention

[0005] This invention provides a cleaning roller brush, a floor scrubber, and a control method thereof to solve the problems of traditional roller brush cleaning methods being limited, having poor cleaning effect on stubborn stains, and existing auxiliary cleaning solutions being complex, costly, and dependent on manual operation. It effectively improves cleaning ability and efficiency, simplifies equipment structure, and optimizes user experience.

[0006] This invention provides a cleaning roller brush, comprising: a roller brush cylinder, wherein an installation cavity is formed inside the roller brush cylinder, and a cleaning component is provided on the outside of the roller brush cylinder; A drive motor is located at one end within the mounting cavity and is used to drive the roller brush to rotate and clean the surface to be cleaned. An eccentric drive mechanism is located at the end of the roller brush away from the drive motor, and is used to cause the end of the roller brush away from the drive motor to move eccentrically, thereby patting and cleaning the surface to be cleaned.

[0007] According to a cleaning roller brush provided by the present invention, the eccentric drive mechanism is disposed at the other end of the mounting cavity, including at least one electromagnet, a counterweight slider adapted to the electromagnet, and a power supply component for supplying power to the electromagnet. When the electromagnet is energized, it attracts the counterweight slider so that the center of gravity of the roller brush is located on the central axis of the roller brush. When the electromagnet is de-energized, it releases the counterweight slider, causing the center of gravity of the roller brush at the end away from the drive motor to deviate from the central axis.

[0008] According to a cleaning roller brush provided by the present invention, the mounting cavity is provided with a counterweight groove corresponding to the electromagnet for accommodating the counterweight slider.

[0009] According to a cleaning roller brush provided by the present invention, the counterweight slider has a U-shaped structure, the opening of the counterweight slider faces the electromagnet, and the counterweight groove is provided with a shape adapted to the counterweight slider.

[0010] According to a cleaning roller brush provided by the present invention, the eccentric drive mechanism includes a plurality of electromagnets and a plurality of counterweight sliders corresponding one-to-one with the plurality of electromagnets, and the plurality of electromagnets are independently powered.

[0011] According to a cleaning roller brush provided by the present invention, the power supply component is an electric slip ring, and a handle is provided at the end of the roller brush away from the drive motor. The power supply contact at the handle is used to supply power to the electric slip ring.

[0012] According to the present invention, a cleaning roller brush is provided, wherein the eccentric drive mechanism is disposed above the roller brush and includes an elastic cavity that abuts against the roller brush and a pipe communicating with the cavity. The pipe is used to fill the cavity with a gas or liquid medium so that the cavity squeezes and pushes the roller brush to pat and clean the surface to be cleaned.

[0013] The present invention also provides a floor scrubbing machine, including the cleaning roller brush as described above.

[0014] The present invention also provides a floor scrubber control method, comprising: in a conventional cleaning mode, controlling the roller brush to rotate to clean the surface to be cleaned; In the tapping cleaning mode, the roller brush is controlled to initiate an eccentric tapping motion while rotating for cleaning.

[0015] According to a floor scrubbing machine control method provided by the present invention, the floor scrubbing machine is equipped with a dirt detection module; The dirt detection module is used to detect dirt in the area to be cleaned. If the level of dirt detected meets the preset conditions, the floor scrubber enters the tapping cleaning mode.

[0016] The cleaning roller brush, floor scrubber, and control method provided by this invention, by adding an eccentric drive mechanism to the non-drive end of the roller brush, enables the roller brush to simultaneously generate an eccentric slapping motion perpendicular to the ground while rotating and cleaning as a whole. This forms a composite cleaning motion mode that combines rotational friction and high-frequency hammering, breaking the limitations of traditional roller brushes that operate only in a single rotational manner. It can efficiently loosen, break up, and peel off various stubborn stains such as dried oil stains, coffee stains, and adhesive residues on the ground, significantly improving the cleaning efficiency and thoroughness of stubborn stains.

[0017] Powerful stain removal is achieved through physical impact, effectively reducing reliance on auxiliary cleaning systems such as specialized cleaning solutions and hot water heating. This streamlined design reduces manufacturing and consumable costs, minimizes potential malfunctions, and enhances overall stability and lifespan. The composite cleaning motion automatically strengthens stain removal, eliminating the need for repeated pushing and pulling, thus reducing user workload and optimizing the human-machine interface. It caters to both quick cleaning of light stains and deep cleaning of stubborn dirt, making it suitable for various home floor cleaning scenarios. Attached Figure Description

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] The following is combined with Figures 2 to 7 The cleaning roller brush 100 of the present invention includes: a roller brush cylinder 110, which is a hollow cylindrical structure with an enclosed mounting cavity inside, providing a stable mounting space for various drive structures and effectively preventing cleaning wastewater, dust, and impurities from entering the interior, thus ensuring the stability of the structure's operation. Cleaning components are evenly arranged on the outer circumference of the roller brush cylinder 110, and each cleaning component is provided with brush bristles 111. The brush bristles 111 make full contact with the surface to be cleaned, achieving the wiping and sweeping of surface dust and stains.

[0026] The drive motor 120 is fixedly installed at one end of the mounting cavity of the roller brush cylinder 110, serving as the power source for the rotation and cleaning of the roller brush 100. The output end of the drive motor 120 is connected to the roller brush cylinder 110, which can drive the entire roller brush cylinder 110 to rotate at a constant speed around its own central axis. By relying on the continuous shearing friction between the roller brush bristles 111 and the ground, the routine cleaning operation of daily ground stains is completed.

[0027] An eccentric drive mechanism is located at the end of the roller brush 100 away from the drive motor 120. It is used to make the end of the roller brush 100 away from the drive motor 120 move eccentrically to beat and clean the surface to be cleaned. The roller brush bristles 111 are combined with a certain frequency of beating action perpendicular to the ground on the basis of rotational friction.

[0028] This invention can switch between different cleaning modes according to the degree of dirt on the ground, adapting to diverse cleaning scenarios. In the normal cleaning mode, the eccentric drive mechanism is not activated, and the roller brush 100 is driven by the drive motor 120 to rotate at a constant speed around a fixed axis, completing the cleaning of ordinary dust and light stains through the sliding friction between the bristles and the ground. When heavy dirt such as dried stains, stubborn oil stains, and adhesive residue are detected on the ground, the device can switch to the tackling enhanced cleaning mode. At this time, the eccentric drive mechanism is activated, causing the non-drive end of the roller brush 100 to deviate from the central axis, so that the roller brush 100 produces controllable eccentric oscillation and vertical tackling motion. Through the composite cleaning method combining rotational friction and vertical high-frequency hammering, it can effectively loosen, break, and peel off stubborn stains firmly attached to the ground, overcoming the shortcomings of traditional single rotation cleaning in terms of insufficient stain removal ability. It can significantly improve the cleaning effect and efficiency of stubborn stains without relying on auxiliary structures such as chemical cleaning liquids and hot water heating.

[0029] In the first implementation, such as Figures 2 to 6 As shown, the eccentric drive mechanism is located at the other end of the mounting cavity, including at least one electromagnet 130, a counterweight slider 131 adapted to the electromagnet 130, and a power supply component for supplying power to the electromagnet 130. When energized, the electromagnet 130 attracts the counterweight slider 131, causing the center of gravity of the roller brush 100 to be located on its central axis. When de-energized, the electromagnet 130 releases the counterweight slider 131, causing the center of gravity of the roller brush 100 at the end away from the drive motor 120 to deviate from the central axis. By setting the electromagnet 130 and the metal counterweight slider 131 at the end of the roller brush 100 away from the drive motor 120, and by controlling the pulse current, the electromagnet 130 generates a periodic attracting and releasing force, which can drive the end of the roller brush 100 to produce a slapping vibration.

[0030] When the equipment is in normal cleaning mode, the power supply component is the electromagnet 130. The electromagnet 130 generates electromagnetic attraction to firmly attract and fix the metal counterweight slider 131, so that the center of gravity of the non-drive end of the roller brush 100 is kept on the central axis of the roller brush 100. The roller brush 100 is driven by the drive motor 120 to rotate smoothly and uniformly around the central axis, and the conventional ground friction cleaning operation is completed by the outer roller brush bristles 111.

[0031] When switching to the eccentric tapping mode for cleaning stubborn stains, the electromagnet 130 is de-energized, the electromagnetic attraction disappears, and the counterweight slider 131 is released. After the counterweight slider 131 is released from its limit position, it undergoes radial displacement under the centrifugal force generated by the high-speed rotation of the roller brush 100, causing the center of gravity of the end of the roller brush 100 away from the drive motor 120 to deviate from the central axis. Since the position of the end of the roller brush 100 near the drive motor 120 is fixed and the axis remains unchanged, the roller brush 100 as a whole forms a controllable eccentric oscillating motion, causing the outer roller brush bristles 111 to simultaneously generate a high-frequency tapping action perpendicular to the ground while rotating and sweeping. Relying on the combined action of rotational friction and mechanical hammering, it effectively removes dried and stubborn stains from the ground, achieving an enhanced cleaning effect.

[0032] Specifically, the mounting cavity is provided with a counterweight slot 132 corresponding to the electromagnet 130, for accommodating the counterweight slider 131. For example... Figure 2 As shown, the electromagnet 130 is fixedly mounted on the upper side inside the brush cylinder 110, and the counterweight groove 132 is arranged below the electromagnet 130 or around the electromagnet 130. The counterweight groove 132 has sufficient room for movement, allowing the counterweight slider 131 to slide in the up and down direction.

[0033] In some embodiments, the counterweight slider 131 adopts a U-shaped one-piece structure. The open end of the counterweight slider 131 is arranged facing the electromagnet 130. The internal contour of the counterweight groove 132 is formed to match the U-shaped counterweight slider 131, ensuring smooth sliding without jamming. Compared with a rectangular block counterweight structure, the U-shaped counterweight slider 131 used in this solution has a larger overall volume and higher overall counterweight mass, which can generate sufficient eccentric torque under centrifugal force, providing a sufficient power basis for the roller brush 100 to achieve stable and reliable eccentric tapping cleaning action.

[0034] Figure 2 An example illustrating a single electromagnet 130 and a counterweight slider 131 is shown, demonstrating a simple structure and lower cost. To further enhance the flexibility of cleaning mode adjustment, in a preferred embodiment, such as... Figure 3 As shown, the eccentric drive mechanism includes multiple electromagnets 130 and multiple counterweight sliders 131 corresponding to each of the multiple electromagnets 130. The multiple electromagnets 130 are arranged independently and are powered and controlled by independent circuits, and their working states do not interfere with each other.

[0035] In actual use, the number of counterweight sliders 131 deployed can be flexibly controlled according to the stubbornness of the stains and the required cleaning intensity. By selectively releasing different numbers of counterweight sliders 131, the overall eccentric force can be precisely adjusted, thereby adjusting the eccentric oscillation amplitude of the roller brush 100 to adapt to the patting cleaning intensity required for different scenarios. For example Figures 4 to 6As shown, this embodiment is equipped with two sets of electromagnets 130 and matching counterweight sliders 131. During operation, either side of the counterweight slider 131 can be released individually, or both sets of counterweight sliders 131 can be released from their magnetic limit at the same time, thereby outputting different levels of striking impact force to meet the needs of gentle cleaning of light stains and powerful removal of heavy stubborn stains.

[0036] Furthermore, such as Figure 2 As shown, the power supply component is an electric slip ring, which includes an electric slip ring stator 133 and an electric slip ring rotor 134. The end of the roller brush 100 away from the drive motor 120 is provided with a handle 135. The handle 135 integrates power supply contacts. By connecting to the circuit, the power is transferred and transmitted through the electric slip ring. Even if the roller brush 100 is in a continuous high-speed rotation state, it can stably supply power to each set of electromagnets 130 inside, ensuring smooth switching between the two working modes of magnetic attraction and power-off release, and continuous and stable power supply.

[0037] In the second implementation, such as Figure 7 As shown, the eccentric drive mechanism is located above the roller brush 100 and includes an elastic cavity 140 that abuts against the roller brush 100 and a pipe 141 communicating with the cavity 140. The pipe 141 can be connected to an external air source or liquid supply device, which can directionally introduce gaseous or liquid pressure media such as compressed air or pressurized oil into the cavity 140. By adjusting the amount and pressure of the medium, the filling degree and overall expansion deformation state of the cavity 140 are changed. When the medium is continuously filled into the cavity 140, the internal pressure of the cavity 140 gradually increases, causing the cavity 140 to expand and deform, thereby forming a continuous squeezing and pushing force on the outer wall of the roller brush 100 that is attached below.

[0038] Since one end of the roller brush 100 is limited and fixed by the drive motor 120, the other end of the roller brush 100 can be driven to deviate from the central rotation axis under the lateral and radial squeezing force of the upper cavity 140. This causes the end of the roller brush 100 away from the motor to produce a regular offset swing, so that the outer bristles of the roller brush 100, on the basis of the regular rotational friction cleaning, simultaneously form a reciprocating downward pressing and patting action towards the ground to be cleaned, and loosen the stubborn stains on the ground with the help of mechanical squeezing and patting force.

[0039] In actual use, the flow rate, pressure, and frequency of medium flow can be adjusted via pipe 141 to flexibly change the expansion amplitude and deformation frequency of cavity 140. This allows for precise adjustment of the eccentric oscillation amplitude, tapping force, and tapping frequency of roller brush 100, adapting to cleaning conditions with varying degrees of dirt. After intensive tapping cleaning, the medium inside cavity 140 can be discharged through pipe 141, relieving pressure and resetting cavity 140. No longer applying pressure to roller brush 100, roller brush 100 returns to its axial position, maintaining only uniform, fixed-axis rotation, resuming the normal cleaning mode.

[0040] like Figure 1 As shown, the present invention also provides a floor scrubbing machine 200, including the cleaning roller brush 100 of the above embodiment. The roller brush 100 is mounted on the floor brush. The floor scrubbing machine 200 is also equipped with a water spraying structure and a dirt suction component. The water spraying structure is used to spray water onto the roller brush 100 to enhance the cleaning effect of the roller brush 100 on the surface to be cleaned. The dirt suction component is used to collect the wastewater and dirt after cleaning into the wastewater tank.

[0041] The present invention also provides a control method for a floor scrubber 200, comprising: In the normal cleaning mode, control the roller brush to rotate 100 degrees to clean the surface to be cleaned; In the tapping cleaning mode, the control roller brush 100 starts an eccentric tapping motion while rotating and cleaning.

[0042] Specifically, the device can switch between two core cleaning operation modes. In the normal cleaning mode, the device controls the drive motor 120 to operate normally, driving the cleaning roller brush 100 to rotate at a constant speed around its own central axis. The daily dust and light stain cleaning work is completed by relying on the friction between the roller brush bristles 111 and the ground. In this state, the eccentric drive mechanism is in standby locked state, the roller brush 100 runs smoothly and consumes less energy, which is suitable for daily whole-house routine cleaning.

[0043] In the tapping cleaning mode, while the roller brush 100 continues to rotate and clean, the device simultaneously controls the eccentric drive mechanism to start working, so that the roller brush 100 superimposed eccentric oscillation action, and completes high-frequency tapping operation while rotating and wiping, using compound motion to enhance the removal effect of stubborn stains.

[0044] In some embodiments, the floor scrubber 200 is equipped with a dirt detection module 210, which can be fixedly installed on the floor brush housing above the roller brush 100 to identify and collect data on the degree of dirt on the area to be cleaned in front of the machine in real time. The dirt detection module 210 can be an infrared photoelectric detection module, a visual image recognition module, a turbidity sensor detection module, etc. The device has a preset dirt level judgment threshold. When the detection module detects that the concentration and adhesion of dirt on the ground reach the preset judgment conditions, the main control system automatically triggers a mode switching command, so that the device automatically switches from the normal cleaning mode to the tapping cleaning mode, which can complete the powerful dirt removal operation without manual intervention. At the same time, the device retains manual operation rights. Users can manually turn the tapping cleaning mode on or off according to their own cleaning needs through the control components such as the machine buttons and touch panel, adapting to personalized cleaning habits.

[0045] Furthermore, the system can automatically match corresponding operating parameters based on the dirt level of the ground detected by the dirt detection module 210, achieving adaptive adjustment of the tapping function. For lightly stubborn stains, it automatically reduces the eccentric swing amplitude and tapping frequency; for severe cleaning conditions such as heavily dried stains and thick layers of oil, it automatically increases the eccentric offset and tapping frequency, thereby precisely adjusting the tapping force and frequency to achieve light tapping for light dirt and strong tapping for heavy dirt, ensuring cleaning effect while reducing unnecessary power consumption and avoiding damage to the ground material from excessive tapping.

[0046] In addition, this control method enables coordinated control of the tapping cleaning mode with the machine's water spraying and suction functions. When the equipment enters tapping cleaning mode, the main control system synchronously adjusts the water spray structure and negative pressure suction components, increasing the water spray flow rate to soften and moisten stains. This, combined with the 100° eccentric tapping action of the roller brush, accelerates stain removal from the ground. Simultaneously, the negative pressure suction is increased, quickly and efficiently sucking up and recovering the loosened wastewater and debris as the stains are loosened, preventing secondary adhesion and residue. When exiting tapping cleaning mode and returning to normal cleaning status, the system synchronously reduces the water spray flow rate and suction power, resuming normal cleaning operations. This coordinated operation of multiple cleaning functions comprehensively improves overall cleaning efficiency and floor cleanliness.

[0047] Furthermore, the 200 floor scrubber has a built-in floor material recognition sensor that can automatically identify different floor types such as wood flooring, ceramic tile, marble, and carpet. For soft and easily damaged wood floors, the system automatically limits the maximum patting amplitude and impact force; for hard ceramic tile and cement floors, it reduces the force limit and outputs high-intensity patting action, effectively protecting the floor surface from wear while powerfully removing dirt.

[0048] Furthermore, the floor scrubber 200 features multiple manual tapping settings, including gentle, standard, and powerful modes. Users can select the appropriate setting based on the actual dirt level, freely switching between different eccentric amplitudes and tapping frequencies to meet diverse manual operation needs such as fine cleaning and deep cleaning of heavy stains.

[0049] Furthermore, during the self-cleaning process of the roller brush 100, the system can initiate a short-term low-frequency tapping action. By using the eccentric oscillation of the roller brush 100 in conjunction with the rinsing with clean water, hair, mud, sand, and dried dirt embedded in the bristle gaps are quickly shaken off, greatly improving the self-cleaning cleanliness of the roller brush 100 and reducing the frequency of manual disassembly and cleaning.

[0050] The cleaning roller brush 100, floor scrubber 200, and control method provided by this invention, by adding an eccentric drive mechanism to the non-drive end of the roller brush 100, enables the roller brush 100 to simultaneously generate an eccentric slapping action perpendicular to the ground while rotating and cleaning as a whole. This forms a composite cleaning motion mode that combines rotational friction and high-frequency hammering, breaking the limitation of the traditional single rotation operation of the roller brush 100. It can efficiently loosen, break up, and peel off various stubborn stains such as dried oil stains, coffee stains, and adhesive residues on the ground, greatly improving the cleaning efficiency and thoroughness of stubborn stains.

[0051] Powerful stain removal is achieved through physical impact, effectively reducing reliance on auxiliary cleaning systems such as specialized cleaning solutions and hot water heating. This streamlined design reduces manufacturing and consumable costs, minimizes potential malfunctions, and enhances overall stability and lifespan. The composite cleaning motion automatically strengthens stain removal, eliminating the need for repeated pushing and pulling, thus reducing user workload and optimizing the human-machine interface. It caters to both quick cleaning of light stains and deep cleaning of stubborn dirt, making it suitable for various home floor cleaning scenarios.

[0052] The cleaning roller brush 100, floor scrubber 200, and control method provided by this invention can achieve the following beneficial effects: By introducing an active vertical tapping function, this tapping action generates instantaneous impact force, effectively loosening and breaking up stubborn stains (such as food residue, dirt, and grease) that are dried or firmly adhered, making them easier to be carried away by the rotating bristles. Its cleaning principle has been upgraded from simple friction and shearing to a composite mode of "impact breaking + friction removal," which is expected to improve the cleaning efficiency of stubborn stains by more than 50%.

[0053] The powerful physical cleaning ability reduces the reliance on high-concentration cleaning solutions or high-temperature hot water. In most cleaning scenarios, room temperature water alone can achieve or even surpass the effect of traditional solutions combined with cleaning solutions, reducing user costs and simplifying the product structure for greater reliability.

[0054] The eccentric drive mechanism can be started and stopped in a controlled manner. The floor scrubber 200 can automatically identify heavily soiled areas through dirt sensors (such as optical or conductivity sensors) and automatically start the tapping mode for focused cleaning. In ordinary cleaning areas, it only uses the rotation mode to save energy and reduce noise, realizing an intelligent cleaning strategy of "heavy dirt, heavy cleaning; light dirt, light cleaning", resulting in a better user experience.

[0055] The eccentric drive mechanism can be integrated inside the roller brush 100 without taking up too much extra space in the whole machine. It requires minimal modification to the existing floor scrubber 200 product structure, making it easy to quickly apply and promote in new models.

[0056] The patting motion helps to shake off fine particles and hair tangled at the base of the bristles, which can alleviate the hair tangling problem of the roller brush 100 to some extent and reduce the frequency of maintenance.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
