Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a cleaning device and cleaning system. Background Technology

[0002] In daily home life, cleaning equipment such as vacuum cleaners play a vital role in maintaining a clean indoor environment. Vacuum cleaners can change the way people clean, improving cleaning efficiency. By using a vacuum cleaner, dust, hair, debris, and other pollutants can be sucked up, and fine particles can be filtered out, achieving highly efficient cleaning.

[0003] Currently, some vacuum cleaner models have their air outlets located close to the motor outlets in their air duct design, resulting in higher noise levels during operation and negatively impacting the user experience. Utility Model Content

[0004] The cleaning equipment and cleaning system provided in this application help reduce the noise generated during the operation of the cleaning equipment, thereby improving the user experience.

[0005] In a first aspect, this application provides a cleaning device, comprising: a floor brush device having an air inlet; and a main unit connected to the floor brush device. The main unit includes: a housing, a dust collection assembly, an airflow drive component, and a power supply device. The housing has an inner cavity communicating with the air inlet. The dust collection assembly, the airflow drive component, and the power supply device are sequentially arranged in the inner cavity along the airflow direction. The housing also has an air outlet communicating with the inner cavity and located downstream of the power supply device along the airflow direction. The airflow drive component is adapted to drive airflow from the air inlet sequentially through the dust collection assembly, the airflow drive component, the power supply device, and the air outlet.

[0006] Thus, the cleaning equipment of this application, through the orderly arrangement of the dust collection component, airflow drive component, and power supply device along the airflow direction, and by having the airflow sequentially pass through these components before being discharged from the cleaning equipment, ensures that the air outlet is farther from the airflow drive component. This effectively extends the air duct of the cleaning equipment, providing a wider buffer space for the airflow and avoiding the high noise caused by the close proximity of the vacuum cleaner and motor air outlets in existing technologies, thereby improving the user experience. Furthermore, as the airflow passes through the power supply device and is discharged from the cleaning equipment, the airflow effectively dissipates heat from the power supply device, providing strong support for its stable operation and extending the overall service life of the cleaning equipment.

[0007] In one possible implementation, the dust collection assembly, the airflow drive, and the power supply are arranged sequentially along the axial direction of the main unit and away from the floor brush device.

[0008] In this way, when the airflow enters the cleaning equipment, it first enters the dust collection component. This component intercepts and collects dust, debris, and other impurities, preventing them from entering the airflow drive component and power supply unit, thus preventing wear, blockage, or other damage. The airflow drive component is positioned between the dust collection component and the airflow drive component, allowing the purified airflow to continuously circulate within the cleaning equipment for efficient cleaning. Placing the power supply unit at the end furthest from the floor brush unit avoids direct contact with contaminated airflow, preventing malfunctions. Furthermore, keeping the power supply unit away from the floor brush unit reduces the risk of collisions due to the complexity of the cleaning environment, ensuring stable operation of the power supply unit.

[0009] In one possible implementation, the inner cavity includes a first accommodating space, a second accommodating space, and a third accommodating space arranged sequentially along the axial direction of the host, wherein the first accommodating space is connected to the air inlet, and the air outlet is connected to the third accommodating space; the dust collection assembly is disposed in the first accommodating space; the airflow driving component is disposed in the second accommodating space; and the power supply device is disposed in the third accommodating space.

[0010] This design allows for optimized functional zoning and layout of the cleaning equipment. The first intake space is directly connected to the air inlet, ensuring that inhaled dust, hair, and other contaminants can be quickly collected and processed by the dust collection components, preventing secondary pollution and airflow obstruction. The third intake space not only connects to the air outlet but also houses the power supply unit, allowing the airflow after passing through the airflow drive components to directly cool the power supply unit, effectively reducing its operating temperature and improving stability and lifespan. Furthermore, this segmented design extends the airflow path, increases the buffer zone, and reduces turbulence and noise.

[0011] In one possible implementation, the housing includes an inner shell and an outer shell, the inner shell defining the first accommodating space, the second accommodating space, and the third accommodating space.

[0012] Thus, by designing an inner and outer shell, the overall sealing of the casing is enhanced, reducing the possibility of airflow leakage and further optimizing the airflow path within the cleaning equipment. Furthermore, the inner shell confines the dust collection components, airflow drive components, and power supply device to different spaces, providing excellent physical isolation. This not only prevents the components from colliding and interfering with each other during operation but also effectively protects them from external impacts.

[0013] In one possible implementation, the dust collection assembly includes: a dust cup having a separation chamber, and a first air inlet and a first exhaust port communicating with the separation chamber; a dust-air separator disposed within the separation chamber for separating impurities and air; and a first filter disposed at the first exhaust port.

[0014] Thus, the dust cup, by providing a separation chamber and a first air inlet and a first exhaust outlet connected to the separation chamber, can provide space for the separation of impurities from air. The dust-air separator, placed within the separation chamber, can efficiently separate impurities from the airflow. Furthermore, the first filter element located at the first exhaust outlet can perform secondary filtration on the air passing through the dust-air separator, further purifying the airflow and preventing it from clogging the airflow drive components.

[0015] In one possible implementation, the first exhaust port is located at one end of the dust cup facing the second accommodating space along the axial direction of the main unit.

[0016] In this way, the airflow can directly enter the second receiving space through the first exhaust port, which not only reduces the detour loss of the airflow inside the dust cup and improves the airflow transmission efficiency, but also enhances the airflow continuity inside the entire cleaning equipment and ensures the stable suction of the cleaning equipment.

[0017] In one possible implementation, the airflow drive has a second air inlet and a second exhaust outlet, the second air inlet being located at one end of the airflow drive along the axial direction of the host, and the second exhaust outlet being located on the periphery of the airflow drive.

[0018] In this way, the airflow drive unit can achieve axial air intake through the second air inlet and radial air exhaust through the second exhaust outlet. Axial air intake allows the airflow to maintain a relatively stable direction and speed when entering the airflow drive unit, reducing airflow turbulence and energy loss, providing stable suction for the cleaning equipment, and thus enhancing cleaning capabilities. Radial air exhaust allows the airflow to be distributed more evenly, avoiding sharp noise caused by concentrated airflow impacting a certain direction, creating a quieter cleaning environment for users.

[0019] In one possible implementation, the host further includes: a first air outlet noise reduction component, which is disposed at the second exhaust port.

[0020] In this way, the first air outlet noise reduction component can effectively buffer and silence the high-speed airflow, reduce the noise generated by the airflow impact, and further reduce the noise level generated during the operation of the cleaning equipment.

[0021] In one possible implementation, the sidewall of the second accommodating space is formed with a first grille opposite to the second exhaust port, and the sidewall of the third accommodating space is formed with a second grille; a connecting duct is defined between the inner shell and the outer shell, the connecting duct connecting the first grille and the second grille.

[0022] In this way, the airflow exiting from the second exhaust port can smoothly enter the connecting duct through the first grille, and then enter the third receiving space through the second grille. This airflow path design makes the airflow within the cleaning equipment more orderly, effectively avoiding airflow turbulence and localized pressure imbalances. Furthermore, the connecting duct can further extend the airflow distance, allowing the airflow to be more adequately buffered and slowed down within the cleaning equipment, thus improving noise reduction.

[0023] In one possible implementation, the connecting duct is a spiral duct surrounding the inner shell.

[0024] Thus, the spiral duct allows airflow to form a spiral upward or downward trajectory as it flows within it. This movement further increases the contact area and contact time between the airflow and the duct wall, allowing the airflow to be more fully buffered and decelerated, thereby improving noise reduction. Furthermore, the spiral duct's layout around the inner shell makes efficient use of the annular space between the inner and outer shells. Without occupying excessive additional space, it increases the duct length, optimizes the internal spatial structure of the cleaning equipment, and makes its structure more compact and rational.

[0025] In one possible implementation, the host unit further includes: sound-absorbing cotton, which is disposed within the connecting air duct.

[0026] Thus, when airflow moves within the connecting duct, the sound-absorbing cotton effectively absorbs noise generated by friction between the airflow and the duct wall, as well as noise generated by the turbulence of the airflow itself. Furthermore, the sound-absorbing cotton also reduces the transmission of noise to the outside through the inner and outer shells.

[0027] In one possible implementation, the host unit further includes a second air outlet noise reduction component, which is disposed on the second grille.

[0028] Thus, when the airflow flows from the second grille into the third receiving space through the connecting air duct, the second air outlet noise reduction component can further reduce the noise generated when the airflow flows in.

[0029] In one possible implementation, the first air outlet noise reduction component includes a sponge component; and / or, the second air outlet noise reduction component includes a sponge component.

[0030] Thus, by using sponge components as the first and / or second air outlet noise reduction components, the sponge components with their rich porous structure can effectively capture and absorb noise carried by the airflow, thereby reducing noise propagation. Furthermore, sponge components are low-cost, easy to obtain and process, and can effectively control the production cost of the cleaning equipment while ensuring noise reduction effectiveness.

[0031] In one possible implementation, the second grille and the air outlet are located on opposite sides of the power supply device along the radial direction of the main unit.

[0032] Thus, the second grille is positioned opposite the air outlet, extending the airflow path within the third containment space and allowing for more effective buffering and deceleration of the airflow. Furthermore, the opposing arrangement of the second grille to the air outlet prolongs the residence time of the airflow within the third containment space, improving heat dissipation for the power supply unit.

[0033] In one possible implementation, the power supply device is spaced apart from the inner wall of the third accommodating space so that airflow flows from the second grille through the gap between the power supply device and the inner wall of the third accommodating space to the air outlet.

[0034] In this way, the gap between the power supply unit and the inner wall of the third enclosure provides a passage for airflow, allowing air to flow around the power supply unit and thus improving heat dissipation efficiency. Furthermore, the gap makes the airflow within the third enclosure more orderly, avoiding turbulence and localized blockages. In addition, the reasonable gap design reduces contact between the power supply unit and the inner wall of the third enclosure, lowering the risk of component damage due to vibration or friction and enhancing the overall stability and durability of the cleaning equipment.

[0035] In one possible implementation, the floor brush device further has a floor brush duct communicating with the air inlet; the housing is also provided with an inlet duct located upstream of the dust collection assembly; the floor brush duct and the inlet duct are connected by a flexible hose.

[0036] In this way, by connecting the floor brush unit and the dust collection component with a flexible hose, the floor brush unit can move freely to cope with various complex cleaning scenarios. At the same time, the flexibility of the hose effectively buffers the vibration and impact during airflow transmission, reducing noise generation.

[0037] Secondly, this application provides a cleaning system, including: a cleaning base station; and a cleaning device as described in the above possible implementations, wherein the cleaning base station is at least configured to clean the cleaning components of the floor brush device of the cleaning device.

[0038] Thus, by employing any of the above-mentioned possible implementation methods for the cleaning equipment, operating noise can be reduced, thereby improving the user experience. Furthermore, the power supply device can be effectively cooled as airflow exits through it, extending the overall lifespan of the cleaning equipment. Setting up cleaning base stations allows for efficient cleaning of the cleaning components, ensuring the floor brushes remain in good working order and improving the overall cleaning effect. This not only saves users time and effort but also extends the lifespan of the floor brush assembly and reduces maintenance costs. Attached Figure Description

[0057] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0058] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0059] As the background section describes, the internal airflow structure of existing vacuum cleaners is typically quite simple. For example, existing vacuum cleaners usually employ a straight airflow duct structure. Furthermore, the air outlet of the vacuum cleaner is relatively close to the air outlet of the motor. For instance, the air outlet of the vacuum cleaner and the air outlet of the motor are arranged opposite each other. In this design, the high-speed airflow generated by the motor is directly exhausted through the air outlet of the vacuum cleaner. Due to the short airflow duct, the high-speed airflow generated by the motor is directly exhausted from the vacuum cleaner, leaving insufficient buffer space and noise reduction path for the airflow. This results in high noise levels during operation of the cleaning equipment, severely impacting the user experience.

[0060] In view of this, this application provides a cleaning device and cleaning system. By arranging a dust collection component, an airflow drive component, and a power supply device in an orderly manner along the airflow direction, and ensuring that the airflow passes sequentially through these components before exiting the cleaning device, the distance between the air outlet and the airflow drive component is increased. This effectively extends the airflow duct of the cleaning device, providing a wider buffer space for the airflow and avoiding the high noise caused by the close proximity of the vacuum cleaner and motor air outlets in existing technologies, thereby improving the user experience. Furthermore, as the airflow exits the cleaning device through the power supply device, it effectively dissipates heat from the device, providing strong support for its stable operation and extending the overall service life of the cleaning device.

[0061] The following is for reference. Figure 1This application provides a cleaning device 1, including a floor brush device 10 and a main unit 20. The cleaning device 1 can be a vacuum cleaner, mite remover, etc. The floor brush device 10 may be equipped with cleaning components such as a roller brush, mop, and bristle brush. The floor brush device 10 can directly act on the area to be cleaned to remove impurities. The floor brush device 10 has an air inlet 11. When the floor brush moves on the ground, it can suck in dust, debris, and other impurities raised during the cleaning process through the air inlet 11 into the cleaning device 1.

[0062] Optionally, the floor brush device 10 may include a housing, a roller brush, and an air inlet 11. The bottom of the floor brush device 10 may be equipped with a roller brush, which may be one, two, or more. The surface of the roller brush may be designed with bristles or rubber strips. These bristles or rubber strips can effectively contact the ground, sweeping up dust, hair, debris, and other contaminants from the ground and conveying them towards the air inlet 11 through rotational motion. Simultaneously, the bottom of the floor brush device 10 may also be equipped with an air inlet 11. The location of the air inlet 11 can be determined according to actual needs and is not limited in this application.

[0063] For example Figure 1 As shown, the floor brush device 10 has two roller brushes. Understandably, the dual-roller brush design allows the floor brush to perform two cleaning operations on the area to be cleaned in a single cleaning cycle, effectively improving cleaning efficiency. As a possible example, the rotation direction and bristle design of the two roller brushes can be optimized for specific purposes. For instance, one roller brush can gather large particles of debris on the area to be cleaned, while the other roller brush can sweep up the gathered debris and push it towards the air inlet 11. This collaborative working method ensures a more thorough cleaning of the area. Furthermore, the two air inlets 11 can each correspond to different areas, allowing for a more even distribution of suction power and avoiding cleaning dead zones. When dealing with a large area to be cleaned, the dual air inlets 11 can simultaneously suck in a large amount of dust and debris, improving cleaning efficiency. At the same time, the dual air inlets 11 can also reduce the risk of clogging to some extent.

[0064] Furthermore, the main unit 20 of the cleaning device 1 is connected to the floor brush device 10. Optionally, the main unit 20 of the cleaning device 1 can be movably connected to the floor brush device 10 so that the angle of the main unit 20 relative to the floor brush device 10 can be adjusted.

[0065] The main unit 20 may include a housing 21, a dust collection assembly 22, an airflow drive component 23, and a power supply device 24. The housing 21 has an inner cavity 211, which communicates with the air inlet 11. The dust collection assembly 22 may be a dust cup assembly or a dust bag assembly, etc., the airflow drive component 23 may be a fan, and the power supply device may be a battery pack.

[0066] The inner cavity 211 is used to accommodate the dust collection assembly 22, the airflow drive component 23, and the power supply device 24. The dust collection assembly 22, the airflow drive component 23, and the power supply device 24 can be arranged sequentially in the inner cavity 211 along the airflow direction. The housing 21 is also provided with an air outlet 212. The air outlet 212 can communicate with the inner cavity 211. Furthermore, the air outlet 212 is located downstream of the power supply device 24. When the cleaning equipment 1 is running, the airflow drive component 23 is adapted to drive the airflow from the air inlet 11 sequentially through the dust collection assembly 22, the airflow drive component 23, and the power supply device 24, and finally discharge through the air outlet 212 near the power supply device 24.

[0067] Understandably, through the coordinated operation of the floor brush device 10 and the main unit 20, the air inlet 11 can be smoothly connected to the inner cavity 211 of the main unit 20, ensuring a stable airflow. The orderly arrangement of the dust collection assembly 22, the airflow drive component 23, and the power supply device 24 along the airflow direction, and the sequential passage of airflow through these components before exiting the cleaning device 1, effectively extends the airflow duct of the cleaning device 1. This provides a wider buffer space for the airflow, avoiding the high noise caused by the close proximity of the vacuum cleaner's outlet and the motor's outlet in existing technologies, thus improving the user experience. Furthermore, as the airflow exits the cleaning device 1 through the power supply device 24, it effectively dissipates heat, providing strong support for the stable operation of the power supply device 24 and extending the overall service life of the cleaning device 1.

[0068] In one possible implementation, the dust collection assembly 22, the airflow drive 23, and the power supply device 24 can be arranged sequentially along the axial direction of the main unit 20. Furthermore, the dust collection assembly 22, the airflow drive 23, and the power supply device 24 are arranged in a manner that gradually moves away from the floor brush device 10.

[0069] Understandably, when the airflow enters the cleaning device 1, it first enters the dust collection component 22. The dust collection component 22 can intercept and collect dust, debris, and other impurities to prevent them from entering the airflow drive component 23 and the power supply device 24, thus preventing wear, blockage, or other damage to these components. The airflow drive component 23 is positioned between the dust collection component 22 and the airflow drive component 24, allowing the purified airflow to continuously circulate within the cleaning device 1 for efficient cleaning. Positioning the power supply device 24 at the end furthest from the floor brush device 10 avoids direct contact between the power supply device 24 and the contaminated airflow, preventing malfunctions. Furthermore, the distance between the power supply device 24 and the floor brush device 10 reduces the risk of collisions due to the complexity of the cleaning environment, ensuring the stable operation of the power supply device 24.

[0070] In one possible implementation, refer to Figure 1 , Figure 3 , Figure 4The inner cavity 211 may include a first receiving space 2111, a second receiving space 2112, and a third receiving space 2113. The first receiving space 2111, the second receiving space 2112, and the third receiving space 2113 are also arranged sequentially along the axial direction of the main unit 20. The first receiving space 2111 is used to house the dust collection assembly 22. The second receiving space 2112 is used to house the airflow drive component 23. The third receiving space 2113 is used to house the power supply device 24. Further, the first receiving space 2111 may communicate with the air inlet 11. The air outlet 212 may communicate with the third receiving space 2113.

[0071] In the specific implementation process, airflow enters the first accommodating space 2111 of the main unit 20 through the air inlet 11. Within the first accommodating space 2111, the dust collection assembly 22 filters and collects impurities from the airflow. Since the airflow drive component 23 within the second accommodating space 2112 provides power to the airflow, the airflow can flow from the first accommodating space 2111 to the second accommodating space 2112, and is then propelled into the third accommodating space 2113. After purification by the dust collection assembly 22 and the action of the airflow drive component 23, the airflow can be discharged from the third accommodating space 2113, completing the entire airflow cycle.

[0072] Understandably, the above-described configuration allows for the functional zoning and layout optimization of the cleaning equipment 1. The first accommodating space 2111 is directly connected to the air inlet 11, ensuring that inhaled dust, hair, and other pollutants can quickly enter the dust collection component 22 for collection and treatment, avoiding secondary pollution and airflow obstruction. The third accommodating space 2113 not only connects to the air outlet 212 but also accommodates the power supply device 24, allowing the airflow after passing through the airflow drive component 23 to directly cool the power supply device 24, effectively reducing its operating temperature and improving stability and service life. Furthermore, this segmented design extends the airflow path, increases the buffer zone, and reduces turbulence and noise.

[0073] In one possible implementation, refer to Figure 1 , Figure 3 , Figure 4 The housing 21 includes an inner shell 213 and an outer shell 214. The inner shell 213 divides the internal space of the housing 21 into different functional areas: a first accommodating space 2111, a second accommodating space 2112, and a third accommodating space 2113. The inner shell 213 provides space for the dust collection assembly 22, the airflow drive component 23, and the power supply device 24, allowing each component to operate orderly within its respective space without interference, thus ensuring the overall stability of the cleaning equipment 1. The outer shell 214 surrounds the inner shell 213 to prevent dust, moisture, and other contaminants from entering the inner shell 213, avoiding damage or corrosion to the internal components.

[0074] Understandably, by setting the inner shell 213 and the outer shell 214, the overall sealing of the housing 21 can be enhanced, reducing the possibility of airflow leakage and further optimizing the airflow path inside the cleaning equipment 1. Furthermore, the inner shell 213 can confine the dust collection assembly 22, the airflow drive component 23, and the power supply device 24 to different spaces, providing excellent physical isolation. This not only prevents the components from colliding and interfering with each other during operation but also effectively protects each component from external impacts.

[0075] In one possible implementation, refer to Figure 1 The dust collection assembly 22 includes a dust cup 221 and a dust-air separator 222. The dust cup 221 has a separation chamber 2211, a first air inlet 2212, and a first exhaust outlet 2213. The separation chamber 2211 can communicate with both the first air inlet 2212 and the first exhaust outlet 2213. Thus, the airflow containing dust and impurities from the air inlet 11 and the floor brush duct 12 can enter the separation chamber 2211 inside the dust cup 221 through the first air inlet 2212. The separation chamber 2211 can separate the dust, impurities, and other solid particles that enter the dust cup 221 with the airflow from the air. The airflow that has completed gas-solid separation in the separation chamber 2211 can flow out of the dust cup 221 through the first exhaust outlet 2213 and enter the second receiving space 2112. Specifically, a dust-air separator 222 can be installed inside the separation chamber 2211. The dust-air separator 222 can be used to separate impurities and air. The dust-air separator 222 can use centrifugal force, gravity, and other principles to separate dust and other solid materials from the air in the separation chamber 2211, allowing them to settle to the bottom of the dust cup 221 or be collected in a specific location. Furthermore, a first filter element 223 is also provided at the first exhaust port 2213.

[0076] It is understandable that the dust cup 221, by providing a separation chamber 2211 and a first air inlet 2212 and a first exhaust port 2213 connected to the separation chamber 2211, can provide space for the separation of impurities and air. The dust-air separator 222, placed inside the separation chamber 2211, can efficiently separate impurities in the airflow. In addition, the first filter element 223, located at the first exhaust port 2213, can perform secondary filtration on the air passing through the dust-air separator 222 to further purify the airflow and prevent the airflow from clogging the airflow drive element 23.

[0077] In one possible implementation, refer to Figure 1 , Figure 2 , Figure 4 The first exhaust port 2213 is located at one end of the dust cup 221. Specifically, the first exhaust port 2213 can be located at one end of the dust cup 221 along the axis of the main unit 20 and facing the second receiving space 2112.

[0078] Understandably, allowing airflow to directly enter the second accommodating space 2112 through the first exhaust port 2213 not only reduces the detour loss of airflow inside the dust cup 221 and improves airflow transmission efficiency, but also enhances the airflow continuity inside the entire cleaning device 1, ensuring the stable suction of the cleaning device 1.

[0079] In one possible implementation, refer to Figure 1 , Figure 2 , Figure 4 The airflow drive component 23 includes a second air inlet 231 and a second exhaust outlet 232.

[0080] The second air inlet 231 can be located at one end of the airflow drive 23 along the axial direction of the main unit 20. Further, the second air inlet 231 can be located at one end of the airflow drive 23 along the axial direction of the main unit 20 and close to the first exhaust port 2213. The second air inlet 231 can correspond to the first exhaust port 2213, so that airflow discharged from the first exhaust port 2213 can enter the airflow drive 23 through the second air inlet 231. The second exhaust port 232 can be located on the periphery of the airflow drive 23, so that airflow is discharged radially along the airflow drive 23.

[0081] Understandably, the airflow drive component 23 can achieve axial air intake through the second air inlet 231 and radial air exhaust through the second exhaust outlet 232. Axial air intake allows the airflow to maintain a relatively stable direction and speed when entering the airflow drive component 23, reducing airflow turbulence and energy loss, and providing stable suction for the cleaning device 1 to enhance cleaning ability. Radial air exhaust allows the airflow to be more evenly distributed and discharged, avoiding sharp noise caused by concentrated airflow impacting a certain direction, creating a quieter cleaning environment for the user.

[0082] In one possible implementation, refer to Figure 1 , Figure 5 The main unit 20 also includes a first air outlet noise reduction component 25. The first air outlet noise reduction component 25 can be disposed at the second exhaust port 232. The first air outlet noise reduction component 25 can be snapped, sleeved, or glued to the second exhaust port 232.

[0083] Understandably, the first air outlet noise reduction component 25 can effectively buffer and silence high-speed airflow, reduce the noise generated by airflow impact, and further reduce the noise level generated during the operation of the cleaning equipment 1.

[0084] In one possible implementation, refer to Figure 1 , Figure 2 , Figure 4 , Figure 5A first grille 2112a is formed on the sidewall of the second accommodating space 2112. The first grille 2112a can be disposed opposite to the second exhaust port 232. A first air outlet noise reduction component 25 can be disposed between the first grille 2112a and the second exhaust port 232. Optionally, the first air outlet noise reduction component 25 can adopt a multi-layer composite structure, with an outer layer of high-strength, impact-resistant plastic frame and an interior filled with porous sound-absorbing sponge. A second grille 2113a is formed on the sidewall of the third accommodating space 2113. Specifically, the first grille 2112a and the second grille 2113a can be arranged in a matrix, and their grids can be designed as rectangles. Further, a connecting air duct 215 can be defined between the inner shell 213 and the outer shell 214. The connecting duct 215 can connect the first grille 2112a and the second grille 2113a, so that the airflow after being processed by the airflow drive 23 can smoothly enter the connecting duct 215 from the second exhaust port 232 and finally be discharged from the cleaning equipment 1 through the second grille 2113a.

[0085] Understandably, the airflow discharged from the second exhaust port 232 can smoothly enter the connecting duct 215 through the first grille 2112a, and then enter the third receiving space 2113 through the second grille 2113a. This airflow path design makes the airflow inside the cleaning device 1 more orderly, effectively avoiding airflow turbulence and local pressure imbalance. Furthermore, the connecting duct 215 can further extend the airflow distance, allowing the airflow to be more adequately buffered and slowed down inside the cleaning device 1, thus improving the noise reduction effect.

[0086] In one possible implementation, refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 The connecting duct 215 can be a spiral duct surrounding the inner shell 213. This spiral duct forms a circular path, allowing airflow to rise or fall in a spiral manner within it. Optionally, guide vanes can be provided on the outer surface of the inner shell 213. These guide vanes help guide the airflow, reduce turbulence, and improve airflow efficiency. The guide vanes can be fixed inside the connecting duct 215 and arranged at a certain angle to optimize the airflow direction.

[0087] Understandably, the spiral duct allows airflow to form a spiral upward or downward trajectory as it flows within it. This movement further increases the contact area and contact time between the airflow and the duct wall, allowing the airflow to be more fully buffered and decelerated, thus improving noise reduction. Furthermore, the spiral duct's layout around the inner shell 213 makes efficient use of the annular space between the inner shell 213 and the outer shell 214. Without occupying excessive additional space, it increases the duct length, optimizes the internal spatial structure of the cleaning equipment 1, and makes its structure more compact and rational.

[0088] In one possible implementation, refer to Figure 1 The main unit 20 also includes sound-absorbing cotton 26. The sound-absorbing cotton 26 can be installed inside the connecting duct 215. The sound-absorbing cotton 26 can be directly pasted or fixed to the inner wall of the connecting duct 215. Furthermore, strips or sheets of sound-absorbing cotton 26 can be used and laid along the spiral path of the connecting duct 215.

[0089] Understandably, when airflow flows within the connecting duct 215, the sound-absorbing cotton 26 can effectively absorb noise generated by friction between the airflow and the duct wall, as well as by the turbulence of the airflow itself. Furthermore, the sound-absorbing cotton 26 can also reduce the transmission of noise to the outside through the inner shell 213 and the outer shell 214.

[0090] In one possible implementation, refer to Figure 1 , Figure 6 The main unit 20 also includes a second air outlet noise reduction component 27. The second air outlet noise reduction component 27 can be disposed at the second grille 2113a. Furthermore, the second air outlet noise reduction component 27 can be disposed on the outside of the second grille 2113a. In this way, the airflow can first pass through the second grille 2113a, and then enter the third receiving space 2113 via the second grille 2113a.

[0091] Understandably, when airflow flows from the second grille 2113a into the third accommodating space 2113 via the connecting duct 215, the second air outlet noise reduction component 27 can further reduce the noise generated when the airflow flows in.

[0092] In one possible implementation, the first air outlet noise reduction component 25 includes a sponge component. Alternatively, the second air outlet noise reduction component 27 includes a sponge component. Or, both the first air outlet noise reduction component 25 and the second air outlet noise reduction component 27 include sponge components. Optionally, the first air outlet noise reduction component 25 and the second air outlet noise reduction component 27 may also include sound-absorbing rubber.

[0093] Understandably, by setting the first air outlet noise reduction component 25 and / or the second air outlet noise reduction component 27 as sponge components, the sponge components with rich pore structures can effectively capture and absorb noise carried by the airflow, thereby reducing noise propagation. Furthermore, sponge components are low-cost, easy to obtain and process, and can effectively control the production cost of the cleaning equipment 1 while ensuring noise reduction effects.

[0094] In one possible implementation, refer to Figure 1 , Figure 6 The second grille 2113a can be disposed opposite to the air outlet 212 on the third receiving space 2113. That is, the second grille 2113a and the air outlet 212 can be located on opposite sides of the power supply device 24 along the radial direction of the main unit 20.

[0095] Understandably, the second grille 2113a is positioned opposite the air outlet 212, extending the airflow path within the third receiving space 2113, allowing for more adequate buffering and deceleration of the airflow. Furthermore, the opposing arrangement of the second grille 2113a with the air outlet 212 prolongs the airflow's residence time within the third receiving space 2113, thus improving the heat dissipation effect on the power supply device 24.

[0096] In one possible implementation, refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 The power supply device 24 is disposed within the third receiving space 2113. Furthermore, there is a gap between the power supply device 24 and the inner wall of the third receiving space 2113, so that the airflow flowing into the third receiving space 2113 via the second grille 2113a can flow between the power supply device 24 and the inner wall of the third receiving space 2113, circling the power supply device 24, and finally flowing out through the air outlet 212. During this process, the airflow can carry away the heat generated by the power supply device 24.

[0097] Understandably, the gap between the power supply device 24 and the inner wall of the third accommodating space 2113 provides a passage for airflow, allowing airflow to circulate around the power supply device 24, thereby improving heat dissipation efficiency. Furthermore, the gap makes the airflow within the third accommodating space 2113 more orderly, avoiding turbulence and localized blockages. In addition, the reasonable gap design reduces contact between the power supply device 24 and the inner wall of the third accommodating space 2113, reducing the risk of component damage due to vibration or friction, and enhancing the overall stability and durability of the cleaning equipment 1.

[0098] In one possible implementation, refer to Figure 1The floor brush unit 10 also includes a floor brush air duct 12. The floor brush air duct 12 can communicate with the air inlet 11. An inlet air duct 216 is also provided on the housing 21, which can communicate with the floor brush air duct 12. Specifically, the inlet air duct 216 can be located upstream of the dust collection assembly 22. Furthermore, the floor brush air duct 12 and the inlet air duct 216 can be connected via a flexible hose 30. Optionally, the flexible hose 30 can be made of a highly elastic, bend-resistant rubber material. A high-strength fiber reinforcement layer can also be embedded inside the flexible hose 30 to ensure sufficient strength while maintaining flexibility, enabling it to withstand a certain degree of tension and compression without breaking.

[0099] In the specific implementation process, the air inlet 11 is connected to the floor brush duct 12. A certain negative pressure environment is formed inside the floor brush duct 12. This negative pressure is generated by the airflow drive component 23 (such as a fan) inside the host 20, so that the air can carry pollutants from the air inlet 11 into the floor brush duct 12, and then be transported to the host 20 for subsequent filtration and dust collection.

[0100] Understandably, connecting the floor brush unit 10 and the dust collection assembly 22 via the flexible hose 30 allows the floor brush unit 10 to move freely to handle various complex cleaning scenarios. At the same time, the flexibility of the flexible hose 30 effectively buffers vibrations and impacts during airflow transmission, reducing noise generation.

[0101] Furthermore, this application embodiment provides a cleaning system including a cleaning base station and the aforementioned cleaning device 1. The cleaning base station is at least configured to clean the cleaning components of the floor brush device 10 of the cleaning device 1, wherein the cleaning components can be a roller brush, mop, bristle brush, or other cleaning components. Furthermore, the cleaning base station may also be equipped with a charging module, which can charge the cleaning device 1 when it returns to the cleaning base station. The cleaning base station may also be configured to collect impurities from the dust collection assembly 22 of the cleaning device 1. The cleaning base station can transfer the dust and debris collected by the cleaning device 1 during operation to a large-capacity dust collection bag or dust collection box assembled within itself. For example, after the cleaning device 1 returns to the cleaning base station, airflow or mechanical devices can be used to transfer the debris in the dust cup 221 to the dust collection bag or dust collection box of the cleaning base station, thereby reducing the frequency of manual cleaning of the dust cup 221 by the user.

[0102] Understandably, by adopting the aforementioned cleaning device 1, operating noise can be reduced, thereby improving the user experience. Furthermore, as airflow exits the cleaning device 1 via the power supply device 24, it effectively dissipates heat, thus extending the overall lifespan of the cleaning device 1. Setting up cleaning base stations allows for efficient cleaning of the floor brush device, ensuring it remains in good working order and improving the overall cleaning effect of the cleaning device 1. This not only saves users time and effort but also extends the lifespan of the floor brush device and reduces the maintenance costs of the cleaning device 1.
