Description

Technical Field

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

[0002] Vacuum cleaners, floor scrubbers and other cleaning equipment are widely used for environmental cleaning in various indoor and outdoor scenarios. Different cleaning equipment can perform various functions such as vacuuming and mopping, thereby maintaining a clean and tidy living and working environment.

[0003] In related technologies, vacuum cleaners typically include a suction head and an operating body connected to the suction head. The suction head can be dragged on the ground, and a handle is located on the top of the operating body. Users support and push or pull the operating body using the handle, thereby moving the suction head. The operating body is equipped with components such as a dust collection box and a fan. The fan generates negative pressure, causing the suction port on the suction head to produce suction, thus achieving the dust collection function.

[0004] However, current vacuum cleaners struggle to remove stubborn dust that adheres to the floor or deep within blankets, resulting in poor cleaning performance. Utility Model Content

[0005] This application provides a cleaning device to solve the technical problem that current vacuum cleaners have difficulty cleaning stubborn dust attached to the ground or deep in the carpet, resulting in poor cleaning effect.

[0006] This application provides a cleaning device, which includes a vacuuming device and a suction cup, the suction cup being movably connected to the vacuuming device; the suction cup is provided with an air intake and an air outlet, the vacuuming device is provided with a fan assembly, a vacuuming duct and an air blowing duct are provided between the suction cup and the vacuuming device, the vacuuming duct is connected to the air intake, the air inlet side of the fan assembly is connected to the vacuuming duct, the air outlet side of the fan assembly is connected to the air blowing duct, and the air blowing duct is connected to the air outlet.

[0007] The suction cup is equipped with a dust guide channel, which connects the air intake and the air outlet.

[0008] The cleaning equipment provided in this application is equipped with a dust suction duct that can generate negative pressure through a fan, and a blower duct that uses positive pressure from the fan to blow out airflow. This allows the cleaning equipment to disperse dust through the airflow blown out of the blower during the cleaning process. In this way, stubborn dust attached to the ground or deep in the carpet can be blown up and more easily sucked into the dust suction duct, thus achieving a better cleaning effect.

[0009] As an alternative implementation, both the air intake and the air outlet face downwards from the bottom of the suction cup.

[0010] With this setup, the air blower can more efficiently disperse dust, while the air intake can quickly suck away the dust, preventing it from overflowing and spreading into the air.

[0011] As an alternative implementation, the air outlet can be located in front of the suction port along the cleaning direction of the suction cup.

[0012] With this setup, during the cleaning process, the air intake can pass through the area where the air blower raises dust, ensuring that the dust raised is sucked into the dust extraction duct.

[0013] As an optional implementation, the air outlet has multiple air blowing zones, which are located at different positions around the air inlet.

[0014] This setup expands the cleaning range of the suction cup, making it easier to clean the corners and edges of the area to be cleaned.

[0015] As an optional implementation, a dust-collecting chamber is provided on the bottom side of the suction cup, with the opening of the dust-collecting chamber facing downwards from the suction cup, and the air outlet is located inside the dust-collecting chamber.

[0016] The suction port is located on the outside of the dust-generating chamber and is adjacent to the dust-generating chamber; the dust guide channel is located on the lower edge of the chamber wall on the side adjacent to the suction port and connects the dust-generating chamber and the suction port.

[0017] Alternatively, the suction port is located inside the dust collection chamber; the blowing port and the suction port are arranged opposite each other on both sides inside the dust collection chamber to form a dust guiding channel between the blowing port and the suction port.

[0018] This design provides space for dust blown up by the airflow, preventing it from overflowing from around the suction cup after being impacted by the airflow.

[0019] As an optional implementation, there can be multiple air outlets, which are spaced apart along the length of the dust-generating chamber.

[0020] This setting increases the amount of air blown onto the surface being cleaned.

[0021] As an optional implementation, the dust collection device may include a dust collection housing, a fan assembly connected to the dust collection housing, the dust collection housing forming a mutually isolated dust collection chamber and an exhaust chamber, the dust collection chamber being connected to a dust collection duct, the air inlet side of the fan assembly being connected to the dust collection chamber, the air outlet side of the fan assembly being connected to the exhaust chamber, and the exhaust chamber being connected to a blower duct.

[0022] This design allows the dust collection housing to form a cavity channel for the air intake and exhaust of the fan assembly, thereby reducing the size and weight of the dust collection device.

[0023] As an alternative implementation, the dust collection device may also include a filter disposed within the dust collection housing, located between the dust collection chamber and the air inlet side of the fan assembly.

[0024] This configuration filters the airflow drawn into the dust collection chamber, preventing dust from contaminating and damaging the fan components, while also preventing dust from mixing into the airflow when it is blown towards the air outlet under the positive pressure of the fan.

[0025] As an optional implementation, the cleaning equipment may also include an exhaust pipe; the dust collection device includes a dust collection housing, a fan assembly connected to the dust collection housing, the dust collection housing forming a dust collection chamber, the dust collection chamber communicating with a dust collection duct, and the air inlet side of the fan assembly communicating with the dust collection chamber; the exhaust pipe is located on the side of the dust collection housing, the first end of the exhaust pipe communicating with the air outlet side of the fan assembly, and the second end of the exhaust pipe communicating with a blower duct.

[0026] With this configuration, the airflow blown out by the positive pressure of the fan assembly can flow more smoothly, reducing wind noise and wind resistance.

[0027] As an optional implementation, the fan assembly may include a fan housing and a fan unit, with the fan unit disposed inside the fan housing; the fan housing has a first exhaust port and a second exhaust port, the first exhaust port being connected to a blowing duct, and the second exhaust port being connected to the external space of the fan housing.

[0028] The cleaning equipment may also include a switching unit disposed on the air outlet side of the fan unit within the fan housing; the switching unit is configured to connect the air outlet side of the fan unit to either the first exhaust port or the second exhaust port.

[0029] With this setting, you can choose whether to enable the dust-generating function based on the specific cleaning scenario.

[0030] This application provides a cleaning device, which includes a vacuuming device and a suction cup, with the suction cup movably connected to the vacuuming device. The suction cup is provided with an air intake and an air outlet. The vacuuming device is provided with a fan assembly. A vacuuming duct and an air blowing duct are provided between the suction cup and the vacuuming device. The vacuuming duct is connected to the air intake.

The air blowing duct is connected to the air outlet. The suction cup is provided with a dust guiding channel, which is connected to the air intake and the air blowing duct.

[0049] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0050] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0051] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0052] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such as a process, method, system, product, or maintenance tool that includes a series of steps or units, not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or maintenance tool.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] Vacuum cleaners typically consist of a nozzle and a main operating unit connected to the nozzle. The nozzle can be dragged on the ground, and a handle is located on the top of the main operating unit. Users move the nozzle by supporting and pushing the main operating unit with the handle. The main operating unit contains components such as a dust collection box and a fan. The fan generates negative pressure, which causes the suction port on the nozzle to produce suction, thus achieving the dust collection function.

[0055] However, the negative pressure suction generated by the suction nozzle of the vacuum cleaner is currently limited, making it difficult to clean stubborn dust attached to the ground or deep in the carpet, resulting in poor cleaning effect.

[0056] To address the aforementioned technical problems, this application provides a cleaning device that combines a suction duct that generates negative pressure using a fan with a blowing duct that utilizes positive pressure from the fan to blow airflow, thereby achieving both suction and dust dispersion functions. During the cleaning process, the device disperses dust through the airflow from the blowing nozzle, effectively lifting stubborn dust adhering to the ground or deep within blankets, making it easier to draw the dust into the suction duct and achieving a better cleaning effect.

[0057] To facilitate understanding, the application scenarios of the cleaning equipment provided in the embodiments of this application will be described first.

[0058] This application provides cleaning equipment with a dust collection function, including but not limited to vacuum cleaners, floor scrubbers, and vacuum and mop combos. The cleaning equipment can be used for household cleaning or for floor cleaning in other indoor or outdoor scenarios. This application does not limit the specific product type or application scenario of the cleaning equipment.

[0059] Figure 1 This is a schematic diagram of the structure of the cleaning equipment provided in the embodiments of this application; Figure 2 for Figure 1 A partial view of position A in the middle; Figure 3 This is a schematic diagram of the bottom of the suction cup in the cleaning device provided in the embodiments of this application.

[0060] See Figures 1 to 3 As shown, this application provides a cleaning device, which includes a vacuum cleaner 100 and a suction cup 200, with the suction cup 200 movably connected to the vacuum cleaner 100. The vacuum cleaner 100 serves as the main structure of the cleaning device and is used by the user to move the suction cup 200 across the surface to be cleaned, allowing the suction cup 200 to suck up dust and debris from the surface.

[0061] The suction cup 200 is provided with an air intake 201 and an air blowing port 202. The dust collection device 100 is provided with a fan assembly 120. A dust collection duct 203 and an air blowing duct 204 are provided between the suction cup 200 and the dust collection device 100. The dust collection duct 203 is connected to the air intake 201. The air inlet side of the fan assembly 120 is connected to the dust collection duct 203. The air outlet side of the fan assembly 120 is connected to the air blowing duct 204. The air blowing duct 204 is connected to the air blowing port 202.

[0062] Understandably, the fan assembly 120 on the vacuum cleaner 100 has a positive pressure side and a negative pressure side. The air inlet on the negative pressure side is connected to the vacuum duct 203, and the air outlet on the positive pressure side is connected to the blower duct 204. When the fan assembly 120 is started, the suction port 201 creates negative pressure to suck in dust and debris from the surface to be cleaned, and the blower port 202 creates positive pressure to blow airflow out onto the surface to be cleaned, thereby stirring up stubborn dust and debris adhering to corners and the ground.

[0063] In some embodiments, the suction cup 200 is provided with a dust guide channel 205, which connects the air intake 201 and the air blower 202. Dust blown by the air blower 202 can enter the air intake 201 through the dust guide channel 205.

[0064] It should be noted that, during the cleaning process, the cleaning device provided in this embodiment can disperse dust through the airflow blown from the air outlet 202. This can blow up stubborn dust adhering to the ground or deep within the blanket, making it easier for the dust to be drawn into the suction duct 203 through the air inlet 201 via the dust guide channel 205, thus expanding the cleanable area of ​​the cleaning device and achieving a better cleaning effect. Furthermore, because the dust guide channel 205 allows the dispersed dust to enter the suction inlet 201 more smoothly, it prevents the dispersed dust from overflowing from the bottom of the suction cup 200 to the outside.

[0065] In some embodiments, both the suction port 201 and the blowing port 202 are oriented towards the bottom of the suction cup 200, so that the blowing port 202 can more efficiently disperse dust, while the suction port 201 can quickly suck away the dust and prevent the dust from overflowing and drifting into the air.

[0066] It is understandable that the air intake 201 can be a long strip structure, and the air intake 201 can extend along the width direction of the suction cup 200, wherein the width direction of the suction cup 200 is perpendicular to the direction of movement of the suction cup 200 during cleaning.

[0067] For example, the blower 202 can be located in front of the suction port 201 along the cleaning direction of the suction cup 200. During the cleaning process, the suction port 201 can pass through the area where the dust is raised by the blower 202, ensuring that the raised dust is sucked into the suction duct 203.

[0068] Figure 4 This is a schematic diagram showing the partitioning of the bottom air outlet of the suction cup in the cleaning device provided in this application embodiment.

[0069] For example, please refer to Figure 4 The air outlet 202 has multiple air blowing zones 202a, which are located at different positions around the air inlet 201, thereby expanding the cleaning range of the suction cup 200 and making it easier to clean the corners of the scene to be cleaned.

[0070] It should be noted that the dust guide channel 205 is set between the air outlet 202 and the air intake 201. Multiple dust guide channels 205 are provided, and the multiple dust guide channels 205 can be distributed at different positions on the adjacent sides of the air intake 201 and the air outlet 202 to improve the efficiency of the dust being sucked into the air intake 201.

[0071] In one possible implementation, a dust-collecting chamber 206 is provided on the bottom side of the suction cup 200, with the opening of the dust-collecting chamber 206 facing downwards from the suction cup 200, and an air outlet 202 is disposed within the dust-collecting chamber 206. The dust-collecting chamber 206 provides a floating space for dust blown up by the air outlet 202.

[0072] It is understandable that the dust raised in the dust chamber 206 can enter the air intake 201 through the dust guide channel 205. The dust guide channel 205 can be an airflow channel set independently of the dust chamber 206, or it can be a gas flow path formed in the dust chamber 206.

[0073] Correspondingly, when the dust guide channel 205 is set independently of the dust chamber 206, the air intake 201 is located outside the dust chamber 206, while when the dust guide channel 205 is formed inside the dust chamber 206, the air intake 201 is located inside the dust chamber 206. This will be illustrated below with different examples.

[0074] Please refer to Figures 1 to 3In some embodiments, the air intake 201 is located outside the dust chamber 206 and is disposed adjacent to the dust chamber 206; the dust guide channel 205 is located on the lower edge of the cavity wall of the dust chamber 206 adjacent to the air intake 201 and connects the dust chamber 206 and the air intake 201.

[0075] It is understandable that the dust blown up by the airflow from the air outlet 202 is drawn into the dust-raising chamber 206 and then into the dust-guiding channel 205. The dust then enters the air intake 201 through the dust-guiding channel 205, thus preventing the dust from overflowing from the sides of the suction cup 200 after being impacted by the airflow.

[0076] For example, the air intake 201 is located on the rear side of the dust collection chamber 206 along the cleaning direction of the cleaning equipment. The air intake 201 faces downwards from the suction cup 200. The dust collection chamber 206 is open downwards from the suction cup 200.

[0077] Figure 9 This is another structural schematic diagram of the cleaning equipment provided in the embodiments of this application; Figure 10 This is a schematic diagram showing the connection between the adapter component and the suction cup in the cleaning equipment provided in the embodiments of this application; Figure 11 A cross-sectional view of the adapter assembly and suction cup in the cleaning equipment provided in the embodiments of this application; Figure 12 This is a schematic diagram of the air intake and air outlet in the cleaning equipment provided in the embodiments of this application.

[0078] Please refer to Figures 9 to 12 In some embodiments, the suction port 201 is located inside the dust collection chamber 206. The blowing port 202 and the suction port 201 are arranged opposite each other on both sides inside the dust collection chamber 206 to form a dust guiding channel 205 between the blowing port 202 and the suction port 201.

[0079] Understandably, the air pressure at the blower 202 is higher than the ambient air pressure. The airflow from the blower 202 enters the dust-collecting chamber 206 and is directed towards the surface to be cleaned, thus lifting up the stubborn dust adhering to the surface. The air pressure at the suction port 201 is lower than the ambient air pressure, allowing the suction port 201 to draw the dust from the dust-collecting chamber 206 into the equipment. The dust guide channel 205 can be a gas flow path formed within the dust-collecting chamber 206 by the pressure difference between the suction port 201 and the blower 202.

[0080] For example, the air outlet 202 is angled downwards from the base relative to the horizontal direction. This way, when the air outlet 202 blows air downwards into the dust collection chamber 206, the airflow direction is at a certain angle relative to the surface to be cleaned. Upon contact with the surface, the airflow more easily stirs up dust along the surface. Furthermore, the angled airflow direction of the air outlet 202 prevents the airflow from vertically impacting the surface and causing dust to overflow around the dust collection chamber 206, thus preventing dust from leaking out of the dust collection chamber 206.

[0081] For example, the air outlet 202 is tilted downwards from the base at an angle α relative to the horizontal direction. Specific values ​​for α include, but are not limited to, 5°, 10°, 30°, 45°, 60°, 75°, 80°, and 85°. This embodiment does not specifically limit this value. The air outlet 202's tilt angle towards the surface to be cleaned reduces airflow resistance, guides the airflow from the surface to be cleaned, and improves the smoothness of the airflow from the air outlet 202.

[0082] It should be noted that in the suction cup 200 provided in this application embodiment, airflow is blown into the dust-raising chamber 206 through the air outlet 202. The positive pressure airflow impacts the surface to be cleaned to achieve the function of dust raising. Dust can be raised in the dust-raising chamber 206, and the suction pipe 320 sucks in the raised dust through the air outlet 201. This can blow up stubborn dust attached to the ground or deep in the blanket, and make it easier to suck the dust into the suction pipe 320, thus having a highly efficient and good cleaning effect.

[0083] For example, there can be multiple air outlets 202, which are distributed at intervals along the length of the dust chamber 206, thereby increasing the amount of air blown onto the surface being cleaned.

[0084] For example, the air outlet 202 can be a perforated structure, which allows the airflow from the air outlet 202 to have a higher flow rate, so that the airflow impacts the surface to be cleaned downwards, which can remove stubborn dust and debris.

[0085] It should be noted that the airflow at the blower 202 is achieved by the positive pressure airflow of the fan assembly 120 on the vacuum cleaner 100. The airflow structure from the fan assembly 120 to the blower duct 204 can be achieved by the vacuum cleaner 100 itself or by an external pipe. The specific structure of the vacuum cleaner 100 will be described in detail below with different examples.

[0086] Figure 5 This is another structural schematic diagram of the cleaning equipment provided in an embodiment of this application.

[0087] Please refer to Figure 5In one possible implementation, the vacuuming device 100 may include a dust collection housing 112, a fan assembly 120 connected to the dust collection housing 112, the dust collection housing 112 enclosing mutually isolated dust collection chamber 111a and exhaust chamber 111b, the dust collection chamber 111a being connected to the vacuuming duct 203, the air inlet side of the fan assembly 120 being connected to the dust collection chamber 111a, the air outlet side of the fan assembly 120 being connected to the exhaust chamber 111b, and the exhaust chamber 111b being connected to the blowing duct 204.

[0088] It is understandable that the dust collection chamber 111a and the exhaust chamber 111b are two independent spaces. The dust collection housing 112 can be used to form the air inlet and outlet channels of the fan assembly 120, thereby reducing the volume and weight of the dust collection device 100.

[0089] For example, the dust collection chamber 111a and the exhaust chamber 111b can be arranged side by side, ensuring smooth airflow in the dust collection chamber 111a and the exhaust chamber 111b.

[0090] For example, the vacuuming device 100 may also include a filter 1145 disposed in the dust collection housing 112. The filter 1145 is located between the dust collection chamber 111a and the air inlet side of the fan assembly 120, thereby filtering the airflow drawn into the dust collection chamber 111a to prevent dust from contaminating and damaging the fan assembly 120, and at the same time preventing dust from being mixed in when the airflow is blown toward the air outlet 202 under the positive pressure of the fan.

[0091] Figure 6 This is a schematic diagram of the structure of the vacuuming device in the cleaning equipment provided in the embodiments of this application; Figure 7 An exploded view of the dust collection housing and air inlet pipe in the cleaning equipment provided in the embodiments of this application.

[0092] Please refer to Figure 6 and Figure 7 and combined Figures 1 to 3 In another possible implementation, the cleaning equipment may also include an exhaust duct 140. The vacuuming device 100 includes a dust collection housing 112, a fan assembly 120 connected to the dust collection housing 112, the dust collection housing 112 forming a dust collection chamber 111a, the dust collection chamber 111a communicating with the vacuuming duct 203, and the air inlet side of the fan assembly 120 communicating with the dust collection chamber 111a. The exhaust duct 140 is located to the side of the dust collection housing 112, with its first end communicating with the air outlet side of the fan assembly 120, and its second end communicating with the blowing duct 204.

[0093] Understandably, the separately designed exhaust duct 140 allows for smoother airflow from the positive pressure blown out by the fan assembly 120, reducing wind noise and wind resistance.

[0094] For example, the exhaust duct 140 can be a flexible duct, such as a corrugated pipe or a rubber hose, etc., and this application embodiment does not specifically limit it.

[0095] In some embodiments, the vacuuming device 100 includes a dust collection housing 112, an air inlet pipe 113, and a flow guiding assembly 114. The air inlet pipe 113 is connected to the dust collection housing 112, and at least a portion of the air inlet pipe 113 is inserted into the dust collection housing 112. The outer wall of the air inlet pipe 113 and the inner wall of the dust collection housing 112 enclose a dust collection chamber 111a. The dust collection chamber 111a is used to store separated dust and debris.

[0096] The air inlet duct 113 is provided with an air inlet 1131 and a cyclone outlet 1132. The air inlet 1131 faces the outside of the dust collection housing 112, and the cyclone outlet 1132 faces the inside of the dust collection housing 112. The flow guiding assembly 114 is disposed inside the dust collection housing 112. The dust collection housing 112 has an air outlet 1121 on the side of the flow guiding assembly 114 away from the air inlet duct 113. The flow guiding assembly 114 is opposite to the cyclone outlet 1132 and at least part of its structure is located inside the air inlet duct 113, so that a cyclone flow channel is formed between the flow guiding assembly 114 and the inner wall of the air inlet duct 113.

[0097] It is understandable that external dust can enter the air inlet duct 113 through the air inlet 1131 and flow out through the cyclone outlet 1132. It will form a cyclone through the cyclone channel between the flow guide component 114 and the air inlet duct 113. The flow guide component 114 can guide the flow of dust, thereby using rotation and centrifugal motion to separate dust and debris.

[0098] It should be noted that in the vacuum cleaner 100 provided in this application embodiment, a dust collection chamber 111a is formed outside the air inlet pipe 113 by utilizing the inner wall of the dust collection housing 112, which makes full use of the space inside the dust collection housing 112. Furthermore, the flow guiding component 114 is set at the top cyclone outlet 1132 of the air inlet pipe 113, and dust and air separation is performed at the end of the air inlet pipe 113. While having a good dust and air separation effect, the volume of the entire vacuum cleaner 100 is reduced, forming a long cylindrical structure. Therefore, when applied to cleaning equipment, it can reduce the overall weight of the cleaning equipment, lower the center of gravity of the machine, avoid the weight being concentrated at the grip end of the cleaning equipment, and improve the user experience.

[0099] In some embodiments, the flow guiding assembly 114 may include a flow guiding blade 1141 disposed within the cyclone outlet 1132. The flow guiding blade 1141 is configured to guide the airflow passing through the cyclone outlet 1132 to form a cyclone, thereby allowing the airflow mixed with dust and debris to rotate and exit the cyclone outlet 1132, thereby using centrifugal force to separate dust and debris from the airflow and improve the efficiency of dust-air separation.

[0100] For example, the flow guiding component 114 may include multiple flow guiding blades 1141, which are spaced apart around the central axis of the air inlet pipe 113. The multiple flow guiding blades 1141 can form multiple flow channels, thereby improving the efficiency and velocity of the airflow forming a cyclone in the air inlet pipe 113, and thus increasing the centrifugal force of dust and debris thrown out during dust-gas separation, resulting in better dust-gas separation effect and efficiency.

[0101] For example, the number of guide vanes 1141 can be two, three, four or more, and this application embodiment does not specifically limit this.

[0102] For example, the guide vane 1141 can be welded to the inner wall of the cyclone outlet 1132. The surface of the guide vane 1141 can be arc-shaped to ensure the smoothness of the airflow when forming a cyclone and reduce wind resistance and wind noise.

[0103] In some embodiments, the flow guiding assembly 114 may include a flow guiding element 1142 and a filter 1145. The flow guiding element 1142 is disposed opposite to the cyclone outlet 1132. The dust collection housing 112 is provided with an air outlet 1121 at one end away from the air inlet pipe 113. The fan assembly 120 is connected to the air outlet 1121. The filter 1145 is disposed between the flow guiding element 1142 and the fan assembly 120.

[0104] Understandably, the cyclone airflow from the cyclone outlet 1132 can be thrown out to the inner wall of the dust collection housing 112 through the guide 1142, thereby achieving a better dust-air separation effect. Furthermore, the tiny dust particles remaining in the airflow can be filtered by the filter 1145 to ensure the cleanliness of the airflow entering the fan assembly 120 and the exhaust airflow.

[0105] In some embodiments, the flow guide 1142 may include a flow guide bracket 1143 and a flow guide ball 1144. The flow guide bracket 1143 is connected to the inner wall of the dust collection housing 112, and the flow guide ball 1144 is connected to the flow guide bracket 1143. At least a portion of the structure of the flow guide ball 1144 is inserted into the cyclone outlet 1132. The airflow flowing out of the cyclone outlet 1132 can be accelerated and rotated and diffused towards the inner wall of the dust collection housing 112 under guidance, thereby improving the dust-air separation efficiency.

[0106] Understandably, the flow guide bracket 1143 serves two purposes: firstly, it fixes the flow guide ball 1144; secondly, when the dust and gas from the cyclone outlet 1132 are discharged, the airflow guided by the flow guide ball 1144 will continue to flow upward and spread outward. The flow guide bracket 1143 can block the airflow and cause the dust and debris separated under centrifugal force to settle downward.

[0107] For example, the guide ball 1144 is coaxially arranged with the air inlet pipe 113, which can ensure the smooth flow of air out of the cyclone outlet 1132 and avoid turbulence at the cyclone outlet 1132.

[0108] In some embodiments, the inner wall of the cyclone outlet 1132 is provided to form an air outlet area, the radial cross-sectional diameter of the air outlet area gradually increases in the direction toward the outside of the cyclone outlet 1132, and the end of the guide ball 1144 is inserted into the air outlet area.

[0109] Understandably, the cyclone outlet 1132 can form a funnel-shaped structure to increase the flow cross-sectional area of ​​the cyclone outlet 1132, which is beneficial for the airflow to diffuse outward from the cyclone outlet 1132, thereby achieving more efficient dust-gas separation. Since the guide ball 1144 is inserted in the air outlet area, the guide ball 1144 will compress the ventilation area of ​​the cyclone outlet 1132, which can increase the flow velocity while the airflow diffuses in all directions, thereby increasing the centrifugal force of dust and debris during dust-gas separation in the cyclone.

[0110] For example, the cross-sectional dimension of the guide ball 1144 along the radial direction of the dust collection housing 112 first increases and then decreases from the guide bracket 1143 towards the interior of the cyclone outlet 1132. Specifically, the cross-sectional dimension of the portion of the guide ball 1144 inserted into the cyclone outlet 1132 gradually decreases. The guide ball 1144 can control the outlet area of ​​the cyclone outlet 1132, thereby controlling the airflow speed and pressure, allowing the airflow to continue rotating after exiting the cyclone outlet 1132, maintaining the dust-air separation effect.

[0111] In some embodiments, the cyclone support is provided with ventilation holes, which connect the dust collection chamber 111a and the air outlet 1121. The ventilation holes are located near the connection point between the guide ball 1144 and the cyclone support. The ventilation holes are used for the airflow after dust and gas separation, and the ventilation holes are located near the root of the guide ball 1144, so that the ventilation holes are as close as possible to the center of the guide support 1143, which can prevent the airflow containing dust from directly entering the through hole when it is discharged from the cyclone outlet 1132.

[0112] It should be noted that the cyclone support can be connected to the inner wall of the dust collection housing 112 by welding, or the cyclone support can be fixed to the inner wall of the dust collection housing 112 by snap-fit ​​and limiting.

[0113] For example, filter 1145 may include a high-efficiency particulate air filter (HEPA filter) that can filter out micron-sized dust impurities, thereby ensuring the cleanliness of the air flowing out of vacuum cleaner 100.

[0114] It should be noted that the air inlet pipe 113 and the filter 1145 can be connected to the dust collection housing 112 in a detachable manner, including but not limited to threaded connection, snap-fit ​​connection, and elastic interference fit, etc. This application embodiment does not make specific limitations in this regard.

[0115] In some embodiments, the outer wall of the air inlet duct 113 is provided with a turbulence portion 1133, which extends toward the inner wall of the dust collection housing 112.

[0116] It is understandable that when the airflow enters the dust collection chamber 111a and rotates to throw out dust and debris, the turbulence part 1133 can block the airflow and dust and debris as the airflow rebounds and sinks, thereby accelerating the falling of dust and debris and preventing the already settled dust from being carried up by the airflow.

[0117] For example, the baffle 1133 can be disposed at the top or middle of the air inlet duct 113. The baffle 1133 can be welded to the outer wall of the air inlet duct 113.

[0118] In some embodiments, there may be multiple turbulence sections 1133, which are distributed circumferentially around the air inlet duct 113. The end of the turbulence section 1133 away from the air inlet duct 113 abuts against the inner wall of the dust collection housing 112, thereby achieving a better turbulence effect and further accelerating the falling of dust and debris into the dust collection chamber 111a.

[0119] It should be noted that when the air inlet pipe 113 is assembled with the dust collection housing 112, the air inlet pipe 113 is inserted into the dust collection housing 112, the lower end of the connecting part is threaded to the dust collection housing 112, and the upper end of the turbulence part 1133 abuts against the inner wall of the dust collection housing 112, thereby maintaining the stability of the air inlet pipe 113 in the dust collection housing 112 and preventing the air inlet pipe 113 from undergoing radial displacement or shaking.

[0120] In some embodiments, a dust collection chamber cover 115 is provided on the dust collection housing 112, and a dust discharge port is provided on the side wall of the dust collection housing 112, which communicates the dust collection chamber 111a with the outside of the dust collection housing 112. The dust collection chamber cover 115 is connected to the dust collection housing 112, and the dust collection chamber cover 115 is movably disposed relative to the dust discharge port to open or close the dust discharge port.

[0121] Understandably, when the cleaning equipment is in normal use, the dust collection chamber cover 115 closes the outlet to prevent dust from leaking out. When it is necessary to clean the dust collection chamber 111a, the dust collection chamber cover 115 can be opened to pour out the dust and debris inside the dust collection chamber 111a from the outlet.

[0122] It should be noted that in the dust collection device 100 provided in this application embodiment, a dust collection chamber 111a is formed by utilizing the space between the inside of the dust collection housing 112 and the air inlet pipe 113. Thus, when it is necessary to clean the dust and debris in the dust collection chamber 111a, it is only necessary to open the dust discharge port on the outer wall of the housing, without having to remove the relevant structure of the dust collection chamber 111a from the cleaning device, thereby improving the convenience of cleaning the dust collection chamber 111a.

[0123] In some embodiments, the cleaning device includes a dust collection housing 112, a fan assembly 120, and a battery assembly 130. The dust collection housing 112 has an air inlet 1131 and an air outlet 1121 at its two axial ends, respectively. The fan assembly 120 is detachably connected to the end of the dust collection housing 112 with the air outlet 1121, and the fan assembly 120 communicates with the air outlet 1121. The battery assembly 130 is detachably connected to the end of the fan assembly 120 opposite to the dust collection housing 112.

[0124] The dust collection housing 112 is used to allow dust and air to circulate and separate the dust and air, storing dust and debris inside. The fan assembly 120 is used to generate airflow, creating negative pressure at the air inlet 1131 of the dust collection housing 112, thereby achieving the dust collection function. The battery assembly 130 provides power to the fan assembly 120, allowing the vacuum cleaner 100 to be used in cleaning equipment either plugged in or unplugged.

[0125] In some embodiments, the dust collection housing 112, the fan assembly 120, and the battery assembly 130 are coaxially arranged. Thus, along the axial direction of the vacuuming device 100, the dust collection housing 112, the fan assembly 120, and the battery assembly 130 can be arranged sequentially to form a portion of the structure, so that the vacuuming device 100 as a whole forms a slender rod-shaped structure.

[0126] Understandably, the dust collection housing 112 provides a channel for dust and air circulation while utilizing its own structure to form a space for separating and storing dust and debris. The fan assembly 120 is located in the middle of the dust collection device 100. Compared to the prior art where the fan is located at the top, the dust collection device 100 in this embodiment is lighter at the end. The top of the dust collection device 100 is formed into a rod-like structure by the battery assembly 130, which makes it easier for the user to hold and operate with less effort.

[0127] It should be noted that the vacuum cleaner 100 provided in this application, when used in cleaning equipment, serves as the main operating component. The coaxially assembled dust collection housing 112, fan assembly 120, and battery assembly 130 form a rod-like structure for the user to hold during use. Because the three components are arranged sequentially, the axial weight distribution of the overall structure of the vacuum cleaner 100 is more even, resulting in a more compact and lightweight design. This reduces the weight on the hand gripping area during use and improves the user experience.

[0128] Please refer to Figures 9 to 11 In some embodiments, the cleaning device may also include an adapter 300 connected between the vacuum cleaner 100 and the suction cup 200, the adapter 300 being configured to allow the vacuum cleaner 100 and the suction cup 200 to move relative to each other.

[0129] The adapter assembly 300 includes an adapter bracket 310, a suction pipe 320, and a blower pipe 330. Both the suction pipe 320 and the blower pipe 330 are disposed in the adapter bracket 310, with the suction pipe 320 passing through the blower pipe 330. The suction pipe 320 and the blower pipe 330 are nested together, connecting the suction cup 200 and the vacuuming device 100 respectively, thereby forming a flow path for suction airflow and a flow path for blower airflow.

[0130] The suction cup 200 is provided with an air intake 201 and an air blowing port 202, and the dust collection device 100 is provided with a dust collection chamber 111a and an exhaust chamber 111b. The two ends of the suction pipe 320 are connected to the air intake 201 and the dust collection chamber 111a respectively, and the two ends of the air blowing pipe 330 are connected to the air blowing port 202 and the exhaust chamber 111b respectively.

[0131] Understandably, the suction port 201 of the suction cup 200 can create negative pressure, allowing the intake airflow to enter the dust collection chamber 111a through the suction pipe 320. Dust and debris in the airflow can be separated from the airflow and collected in the dust collection chamber 111a. The airflow exiting the dust collection chamber 111a is clean air after dust-air separation, which can be recirculated through the exhaust chamber 111b. The airflow in the exhaust chamber 111b enters the suction cup 200 through the blower pipe 330 and is blown from the blower port 202 of the suction cup 200 onto the surface to be cleaned, thus achieving the dust-removing function. In this way, airflow circulation is formed, making it easier to clean the dust attached to the surface to be cleaned, improving cleaning efficiency and cleaning effect.

[0132] It should be noted that the suction pipe 320 and the blower pipe 330 in the cleaning equipment provided in this application embodiment are nested and connected between the vacuuming device 100 and the suction cup 200. The structure is more compact and occupies less space. Both the suction pipe 320 and the blower pipe 330 are flexible pipes. When the suction cup 200 and the vacuuming device 100 move relative to each other, the suction pipe 320 and the blower pipe 330 will not interfere with the turning of the suction cup 200, thus ensuring the flexibility of the cleaning equipment operation.

[0133] Furthermore, the return of clean airflow in the blower tube 330 utilizes the space between the outer wall of the suction tube 320 and the inner wall of the blower tube 330. The airflow blown out by the blower tube 330 will not affect the airflow in the suction tube 320. The positive pressure airflow blown out by the blower tube 330 can be directly blown onto the surface to be cleaned through the air outlet 202 of the suction cup 200. This can blow up stubborn dust attached to the ground or deep in the blanket, making it easier to suck the dust into the device, resulting in a highly efficient and effective cleaning effect.

[0134] In this embodiment, the cleaning device can have multiple working modes, including but not limited to ordinary vacuuming mode and dust-spraying mode. When the ordinary vacuuming mode is activated, dust can be sucked in from the suction port 201 while the blowing port 202 does not blow out airflow. When the dust-spraying mode is activated, the suction port 201 generates negative pressure to suck in dust while the blowing port 202 blows out airflow to disperse the dust, thereby improving the cleaning efficiency.

[0135] Users can switch between different working modes according to specific usage scenarios. For example, when cleaning floors with relatively little dust, the normal vacuuming mode can be used; when cleaning indoor corners or areas where chairs are placed, the dust-dispersing mode can be used. The structure of the fan assembly 120 that enables the switching of the above-mentioned functional modes is described in detail below.

[0136] Figure 8 This is a schematic diagram of the air outlet of the fan assembly in the cleaning equipment provided in the embodiments of this application.

[0137] Please refer to Figure 8 and combined Figures 1 to 3 In some embodiments, the fan assembly 120 may include a fan housing 121 and a fan unit 122. The fan unit 122 is disposed inside the fan housing 121. The fan housing 121 has a first exhaust port 1211 and a second exhaust port 1212. The first exhaust port 1211 is connected to the air blowing duct 204, and the second exhaust port 1212 is connected to the external space of the fan housing 121.

[0138] The cleaning equipment may also include a switching unit 123, which is disposed on the air outlet side of the fan unit 122 inside the fan housing 121. The switching unit 123 is configured to connect the air outlet side of the fan unit 122 with either the first exhaust port 1211 or the second exhaust port 1212.

[0139] Understandably, when the normal vacuuming mode is activated, the switching unit 123 can switch to connect the air outlet side of the fan unit 122 with the second exhaust port 1212. This allows the dust-laden air drawn in from the suction port 201 by the negative pressure of the fan unit 122 to be filtered and then discharged into the outside atmosphere. When the dust-spraying mode is activated, the switching unit 123 can switch to connect the air outlet side of the fan unit 122 with the first exhaust port 1211. This allows the dust-laden air drawn in from the suction port 201 by the negative pressure of the fan unit 122 to be filtered and then blown from the blowing port 202 through the blowing duct 204 towards the surface to be cleaned, achieving the dust-spraying function.

[0140] For example, the switching unit 123 may include a motor and a movable plate. The motor can drive the movable plate to rotate, change the airflow direction on the air outlet side of the fan unit 122, and realize that the air outlet side of the fan unit 122 can be selectively connected to the first exhaust port 1211 and the second exhaust port 1212.

[0141] This application provides a cleaning device, which includes a vacuuming device and a suction cup, with the suction cup movably connected to the vacuuming device. The suction cup has an air intake and an air outlet. The vacuuming device has a fan assembly. A vacuuming duct and an air blowing duct are provided between the suction cup and the vacuuming device. The vacuuming duct is connected to the air intake. The air inlet side of the fan assembly is connected to the vacuuming duct, and the air outlet side of the fan assembly is connected to the air blowing duct. The air blowing duct is connected to the air outlet. The suction cup has a dust guide channel, which is connected to the air intake and the air blowing duct. This dust can be blown up from corners or chair legs, making it easier for the dust to be drawn into the vacuuming duct through the air intake, thus expanding the cleanable area of ​​the cleaning device and achieving a better cleaning effect.

[0142] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
